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

       GLOBAL DECISIONS GROUP LLC                     MCM GROUP, INC.

         This Information Statement/Prospectus is being furnished, among certain
other persons and entities, to holders of Class A Common Stock, par value $.01
per share (the "Class A Common Stock"), Class B Common Stock, par value $.01 per
share (the "Class B Common Stock"), and Class C Common Stock, par value $.01 per
share (the "Class C Common Stock", and together with the Class A Common Stock
and Class B Common Stock, the "MGI Common Stock"), of MCM Group, Inc., a
Delaware corporation ("MGI"), and relates to the merger (the "Merger") of GDG
Merger Corporation, a Delaware corporation ("Sub"), with and into MGI, pursuant
to the Plan of Merger and Exchange Agreement dated as of August 1, 1997 (the
"Merger Agreement") by and among MGI, Global Decisions Group LLC, a Delaware
limited liability company (the "Parent"), Sub, a wholly owned subsidiary of the
Parent, the stockholders (the "CERA Stockholders") of Cambridge Energy Research
Associates, Inc., a Massachusetts corporation ("CERA"), and The Goldman Sachs
Group, L.P., a Delaware limited partnership ("Goldman"). The Clayton & Dubilier
Private Equity Fund IV Limited Partnership ("C&D Fund IV"), which holds
approximately 83% of the outstanding MGI Common Stock, has approved the Merger,
thereby providing the requisite stockholder approval therefor.

         On the day immediately preceding the closing of the Merger and the
Exchange (as defined below), McCarthy, Crisanti & Maffei, Inc., a New York
corporation and a wholly owned subsidiary of MGI ("MCM"), intends to lend up to
$25,000,000 to CERA (the "CERA Distribution Loan"), and CERA will apply a
portion of such funds, together with CERA's available cash, to the extent
necessary, to make a distribution in cash to the CERA Stockholders in an
aggregate amount equal to $21,510,000 and will apply the remainder of such funds
and available cash to purchase a portion of the limited partnership interest in
Cambridge Energy Research Associates Limited Partnership ("CERA LP") held by
Goldman for a purchase price of $2,390,000 (collectively, the "CERA Cash
Distribution").

         Pursuant to the Merger Agreement, among other things, (a) Sub will be
merged with and into MGI, which will be the surviving corporation, MGI will
become a wholly owned subsidiary of the Parent, and each outstanding share of
MGI Common Stock (excluding treasury shares and shares held by stockholders who
perfect their dissenters' rights) shall be converted into the right to receive
9.55555 units of capital of the Parent ("Units") representing limited liability
company interests in the Parent, (b) the CERA Stockholders will exchange each
outstanding share of Common Stock, par value $.01 per share, and Non-Voting
Common Stock, par value $.01 per share, of CERA (collectively, the "CERA Common
Stock") owned by them for 5.17956 Units, the right to receive from 0.49875 to
2.94851 additional Units upon the attainment of certain revenue growth rates by
CERA and a contingent option to purchase 0.37028 additional Units, at a per Unit
exercise price equal to $34.53, upon the attainment of certain revenue growth
rates by CERA (the "CERA Exchange") and (c) Goldman will exchange the portion of
the limited partnership interest in CERA LP owned by it after the CERA Cash
Distribution for 150,000 Units, the right to receive from 14,444 to 85,389
additional Units upon the attainment of certain revenue growth rates by CERA and
a contingent option to purchase 9,874 additional Units, at a per Unit exercise
price equal to $34.53, upon the attainment of certain revenue growth rates by
CERA (the "Goldman Exchange"). Such numbers of Units are subject to adjustment
as provided in the Merger Agreement and described herein. The CERA Exchange and
the Goldman Exchange are referred to collectively as the "Exchange" and the
Merger and the Exchange are referred to collectively as the "Transactions." See
"Summary -- The Merger and the Exchange," "The Limited Liability Company
Agreement," Annex A and Annex B.

         Each stockholder of MGI has the right to dissent from the Merger and
demand payment of the fair value of his shares. The right of any stockholder to
receive such payment is contingent upon strict compliance with the requirements
of Section 262 of the Delaware General Corporation Law. The full text of Section
262 of the Delaware General Corporation Law is set forth in Annex C to this
Information Statement/Prospectus. See also "The Merger and the Exchange --
Appraisal Rights" for a summary of the requirements of such Section 262.

         Immediately after the consummation of the Merger and the Exchange, it
is currently anticipated that a total of 4,731,835 Units will be outstanding.

         Promptly after the date the Merger and the Exchange are consummated,
the Parent will sell to CERA, for a purchase price per Unit equal to the value
of a Unit on the Closing Date (as defined herein) as determined pursuant to the
Merger Agreement, and CERA will grant to certain employees of or consultants to
CERA (the "CERA Employees"), pursuant to the Cambridge Energy Research
Associates, Inc. LLC Unit Grant Plan (the "CERA Unit Grant Plan"), (i) an
aggregate of 106,875 Units and (ii) a right to receive an aggregate of from
10,291 to 60,840 additional Units (the "CERA Employee Contingent Units") upon
the attainment of certain revenue growth rates by CERA. After the grant of such
106,875 Units to the CERA Employees, it is currently anticipated that a total of
4,838,710 Units will be outstanding.
<PAGE>   2
         After consummation of the Merger and the Exchange and the issuance of
Units to the CERA Employees, and assuming the exercise of all Contingent Options
and the grant of all contingent Units to the CERA Stockholders, all contingent
Units to Goldman and all CERA Employee Contingent Units, it is currently
anticipated that a total of 5,791,344 Units would be outstanding.

         Promptly after the date the Merger and the Exchange are consummated,
CERA will also grant options to purchase an aggregate of 231,500 Units, at an
exercise price of $18.31 per Unit, to certain employees of and consultants to
CERA pursuant to the Cambridge Energy Research Associates, Inc. LLC Unit Option
Plan (the "CERA Option Plan"). In addition, each outstanding option to purchase
MGI Common Stock granted under the MCM Group, Inc. Special Stock Option Plan
(collectively, the "MGI Special Options") and each outstanding option to
purchase MGI Common Stock granted under the MCM Group, Inc. Stock Option Plan
(collectively, the "MGI Employee Options" and together with the MGI Special
Options, the "Existing MGI Options") shall automatically be converted into an
equivalent option to purchase 9.55555 Units from MGI at an exercise price of
either $10.47 per Unit or $15.03 per Unit. As a result, Existing MGI Options to
purchase an aggregate of 867,912 Units will be outstanding after such
conversion.

         In addition, on the date the Merger and the Exchange are consummated,
MGI will grant options (the "Brera Options") to purchase an aggregate of 33,444
Units to Brera Capital Partners, LLC ("Brera") or its designees, at an exercise
price of $23.55 per Unit, and CERA will grant options (the "Jordan Options") to
purchase an aggregate of 11,132 Units to Mr. Edward G. Jordan ("Jordan"), at an
exercise price of $23.55 per Unit.

         The number of Units to be issued in connection with the Merger and the
Exchange and the other transactions contemplated by the Merger Agreement may be
adjusted so that the per Unit value as of the date the Merger and the Exchange
are consummated will be equal to ten dollars.

         This Information Statement/Prospectus also constitutes a Prospectus of
the Parent relating to the issuance of 3,338,710 Units to MGI stockholders in
the Merger. Other securities to be issued in connection with the transactions
described in this Information Statement/Prospectus will be issued in private
placements or registered on separate registration statements.

             THE UNITS OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK.

RECOMMENDATION OF THE MGI BOARD OF DIRECTORS

         The Board of Directors of MGI has approved the Merger Agreement, and
the Board of Directors believes the Merger and the Exchange and the consummation
of the other transactions contemplated by the Merger Agreement are in the best
interest of MGI and its stockholders. C&D Fund IV, which holds 287,038 shares of
MGI Common Stock as of the date hereof, or approximately 83% of the outstanding
MGI Common Stock, has voted all of such shares in favor of the Merger, thereby
providing the requisite stockholder approval therefor.

THE MERGER AND THE EXCHANGE

         General. 
         The Merger Agreement provides that on the day of the closing of the
Merger and the Exchange (the "Closing Date"), Sub, a wholly owned subsidiary of
the Parent, shall merge with and into MGI. At the time the Merger becomes
effective, each share of MGI Common Stock (excluding treasury shares and shares
held by stockholders who perfect their dissenters' rights) shall cease to be
outstanding and shall be converted into the right to receive Units, as provided
in the Merger Agreement. MGI shall be the surviving corporation of the Merger
and as a result shall become a wholly owned subsidiary of the Parent. MCM's
existence will not be affected by the Merger and the Exchange. Following the
Merger, MGI shall continue to be governed by the laws of the State of Delaware.

         Simultaneously with the Merger, the Parent will acquire all of the
outstanding equity interests in CERA through the Exchange. The cash portion of
the consideration to be paid to the CERA Stockholders and Goldman for such
equity interests will be paid through the CERA Cash Distribution. In order to
take advantage of certain tax benefits arising from CERA's current status as an
S corporation, the portion of the CERA Cash Distribution to be paid to the CERA
Stockholders (in an aggregate amount equal to $21,510,000) will not be paid
directly by the Parent or MGI, but instead will be paid by CERA through the
mechanism of a cash distribution by CERA to its stockholders on the day
immediately preceding the Closing Date. The remainder of the CERA Cash
Distribution will be paid through the purchase by CERA, for a purchase price of
$2,390,000, of a portion of the limited partnership interest in CERA LP held by
Goldman. Pursuant to the Merger Agreement, MGI has agreed to cause MCM to make
the CERA Distribution Loan to CERA in order to provide CERA with the funds to
make the CERA Cash Distribution. MCM intends to make the CERA Distribution Loan
to CERA on the day immediately preceding the Closing Date. The CERA Stockholders
have agreed in the Merger Agreement to cause CERA to apply a portion of the
proceeds from such loan, together with CERA's available cash, to the extent
necessary, to make the CERA Cash Distribution. The Parent expects that the CERA
Distribution Loan will be financed through MCM's available cash and borrowings
by MCM under a senior bank Credit Agreement (the "Credit Agreement") to be
entered into shortly before the CERA Distribution Loan is made. Such borrowings
under the Credit Agreement will be made by MCM rather than by the Parent
because, as a holding company with no substantial business operations, the
Parent would be able to meet loan payment obligations only through transfers of
funds from its subsidiaries and, because the Parent will be treated as a
partnership for tax purposes, the holders of Units would be taxed on any
dividends paid to the Parent by its subsidiaries to fund such obligations.

                                       9
<PAGE>   12
         The Merger Agreement also provides that on the Closing Date, the CERA
Stockholders will exchange the shares of CERA Common Stock owned by them for
Units, the right to receive the CERA Contingent Units (as defined herein) and
Contingent Options to purchase Units, and that Goldman will exchange the
portion of the limited partnership interest in CERA LP owned by it after the
CERA Cash Distribution for Units, the right to receive the Goldman Contingent
Units (as defined herein) and Contingent Options to purchase Units. As a
result, CERA will become a wholly owned subsidiary of the Parent. Following the
Exchange, CERA shall continue to be governed by the laws of the Commonwealth of
Massachusetts. Immediately upon completion of the Goldman Exchange, the Parent
will transfer or cause to be transferred to CERA the limited partnership
interest in CERA LP acquired from Goldman in the Goldman Exchange. Upon such
transfer, CERA will become the sole partner of CERA LP and CERA LP will be
dissolved by operation of law (the "CERA Roll-up").

         Upon consummation of the Merger and the Exchange, the anticipated
ownership structure of the Parent and its subsidiaries will be as follows:

</TABLE>

         The Merger and the Exchange have been structured to combine the
economic interests in MGI and CERA of the MGI stockholders, the CERA
stockholders and Goldman through an entity that is not subject to tax. One of
the primary benefits of having a limited liability company (rather than a
corporation) be the holding company for MGI and CERA will be that no corporate
income tax will be payable if the Parent decides to sell either MGI or
CERA. If the Parent were structured as a corporation, upon the sale of MGI or
CERA, the Parent would be subject to tax on any gain, and the stockholders of
the Parent also would be subject to tax upon the distribution of the after-tax
sales proceeds. Because the Parent intends to be treated for federal income tax
purposes as a partnership rather than a corporation, it will not be a taxable
entity. Accordingly, any gain from any sale of the Parent's interest in either
MGI or CERA would not be taxed at the Parent level, but instead would be passed
through to Unitholders and taxed only to them.

         Upon consummation of the Merger and the Exchange, the Parent will own
two principal assets, its interest in CERA and its interest in MGI. Accordingly,
the Parent's results of operations will be dependent on the successful and
continued operation of both CERA and MGI (instead of MGI only, as is currently
the case). In particular, if either CERA or MGI experiences decreased demand for
its services or increased competition or otherwise suffers a material adverse
change in its business, the Parent's results of operations may be materially
adversely affected.


                                       10
<PAGE>   13
         On the Closing Date, MGI will also grant the Brera Options to Brera or
its designees, and CERA will grant the Jordan Options to Jordan. In addition,
each Existing MGI Option shall automatically be converted into an equivalent
option to purchase Units. The Merger Agreement also provides that promptly after
the Closing Date, the Parent will sell to CERA, and CERA will grant to the CERA
Employees, pursuant to the CERA Unit Grant Plan, Units and rights to receive
CERA Employee Contingent Units. CERA will also grant options to purchase an
aggregate of 231,500 Units to certain employees of or consultants to CERA,
pursuant to the CERA Option Plan.

         A copy of the Merger Agreement is set forth as Annex A of this 
Information Statement/Prospectus.

         Immediately after the consummation of the Merger and the Exchange, it
is currently anticipated that a total of 4,731,835 Units will be outstanding.
The number of Units to be issued in connection with the Merger and the Exchange
and the other transactions contemplated by the Merger Agreement will be subject
to adjustment such that the per Unit value as of the Closing Date will be equal
to ten dollars. See "The Merger and the Exchange--Structure and Terms of the
Merger and the Exchange."

         Consideration to be Received by Holders of MGI Common Stock.

         The Merger Agreement provides that, at the effective time of the
Merger, each outstanding share of MGI Common Stock (excluding treasury shares
and shares held by stockholders who perfect their dissenters' rights) shall be
converted into the right to receive 9.55555 Units.

         Consideration to be Received by the CERA Stockholders.

         The Merger Agreement provides that at the closing of the CERA Exchange,
the CERA Stockholders shall exchange each outstanding share of CERA Common Stock
for:

         (1)  5.17956 Units;

         (2)  a right to receive, in the event that CERA attains a sixteen
              percent or higher compound annual revenue growth rate over a
              three-year period ending June 30, 2000 (subject to acceleration on
              the occurrence of certain events), from 0.49875 to 2.94851
              additional Units (the "CERA Contingent Units"); and  

         (3)  an option, contingent upon the attainment of at least a twenty
              percent compound annual revenue growth rate over a three-year
              period ending June 30, 2000 (subject to termination prior to the
              end of such three-year period upon the occurrence of certain
              events) (a "Contingent Option"), to purchase 0.37028 Units at a
              per Unit exercise price equal to $34.53

(collectively, the "CERA Consideration").

         Consideration to be Received by Goldman.

         The Merger Agreement provides that at the closing of the Goldman
Exchange, Goldman shall exchange the portion of the limited partnership interest
in CERA LP owned by it following the CERA Cash Distribution for:

         (1)  150,000 Units;      

         (2)  a right to receive, in the event that CERA attains a sixteen
              percent or higher compound annual revenue growth rate over a
              three-year period ending June 30, 2000 (subject to acceleration on
              the occurrence of certain events), from 14,444 to 85,389
              additional Units (the "Goldman Contingent Units" and together with
              the CERA Contingent Units and the CERA Employee Contingent Units,
              the "Contingent Units"); and

         (3)  a Contingent Option to purchase 9,874 Units

(collectively, the "Goldman Consideration").

         Certain Transactions After the Merger and the Exchange.


         Promptly after the Closing Date, the Parent will sell to CERA, and CERA
will grant to the CERA Employees, pursuant to the CERA Unit Grant Plan, (i) an
aggregate of 106,875 Units and (ii) the right to receive an aggregate of from
10,291 to 60,840 CERA Employee Contingent Units.

         After consummation of the Merger and the Exchange and the issuance of
Units to the CERA Employees, it is currently anticipated that 4,838,710 Units
will be outstanding (or 5,791,344 Units assuming the exercise of all Contingent
Options and the receipt of all CERA Contingent Units, all Goldman Contingent
Units and all CERA Employee Contingent Units). See "The Merger and the
Exchange--Structure and Terms of the Merger and the Exchange."

         Ownership of Units. 

         The following table sets forth the expected ownership of the Units upon
consummation of the Merger and the Exchange both on a primary and fully-diluted
basis, including the grant of Units to the CERA Employees and assuming the
exercise of all Contingent Options and options to purchase Units granted to
employees of or consultants to CERA and MGI or to Brera or Jordan (whether
vested or unvested), and the receipt of all Contingent Units:

         Accounting Treatment.

         The Merger will be accounted for at historical cost. The Exchange
will be accounted for under the purchase method of accounting.

         Effective Time. 

         If all required consents and approvals are obtained, and the other
conditions to the obligations of the parties to consummate the Merger and the
Exchange are either satisfied or waived (as permitted), the Merger will be
consummated and will become effective on the date and at the time that a
Certificate of Merger, reflecting the Merger, is filed with the Secretary of
State of the State of Delaware (the "Effective Time"), and the Exchange will be
consummated and will become effective on the date and at the time that the CERA
Stockholders exchange their shares of CERA Common Stock for Units, the CERA
Contingent Units and Contingent Options, and Goldman exchanges the portion of
the limited partnership interest in CERA LP owned by it following the CERA Cash
Distribution for Units, the Goldman Contingent Units and a Contingent Option.
See "The Merger and the Exchange--Effective Time."

         Comparative Rights of Stockholders of MGI and Holders of Units.

         The rights of the holders of MGI Common Stock are currently governed by
the Delaware General Corporation Law ("DGCL") and by the MGI Certificate of
Incorporation and By-Laws. The rights of holders of MGI Class C Common Stock are
also governed in part by the management stock subscription agreements that each
such holder has entered into with MGI. As a result of the Merger, the holders of
MGI Common Stock (other than stockholders exercising dissenters' rights) will
become holders of Units and as such their rights will be governed by the
Delaware Limited Liability Company Act (the "Delaware Act") and by the Parent's
Certificate of Formation and the Amended and Restated Limited Liability Company
Agreement of the Parent (the "LLC Agreement"), the form of which is attached as
Annex B to this Information Statement/Prospectus. As a result, certain rights
with respect to holders of MGI Common Stock will differ considerably from their
respective rights as Unit holders following the Merger. See "The Limited
Liability Company Agreement" and "Comparison of Stockholder and Unit Holder
Rights." In particular, the rights of holders of Units will be subject to
certain requirements not currently imposed upon holders of MGI Common Stock,
such as requirements with respect to the election of directors, the vote
required in order to authorize certain actions to be taken by the Parent and the
parties whose consent will be required in order to amend particular provisions
of the LLC Agreement. The existence of such requirements, while providing for
desirable efficiency in connection with Parent's operations and for other
corporate purposes, may make it more difficult for a holder of Units (other than
C&D Fund IV) to influence or affect the Parent's actions. However, because C&D
Fund IV holds over 80% of the outstanding shares of MGI Common Stock, other
holders of MGI Common Stock currently do not have a significant ability to
influence or affect MGI's actions. See "Comparison of Stockholder and Unit
Holder Rights" and "The Limited Liability Company Agreement."

         Unit holders will also not be entitled to appraisal rights. The right
of a Member (as defined herein) to receive distributions from the Parent will
also be somewhat different than the right of a holder of MGI Common Stock to
receive dividends and distributions from MGI. Holders of MGI Common Stock are
currently entitled to receive equivalent per share dividends


                                       13


<PAGE>   16
and other distributions from MGI if, as and when declared by the Board of
Directors of MGI. Members will also generally be entitled to receive equivalent
per Unit distributions from the Parent, except that in the case of certain
extraordinary distributions as a result of events such as a sale or spin-off of
MGI or CERA, certain adjustments will be made in respect of the rights to
receive Contingent Units if such Units have not yet been issued. Distributions
will be paid to Members at the discretion of the Board of Directors of the
Parent, except that the Parent will make distributions, to the extent of
available cash, necessary for holders of Units to pay tax liabilities.

         The shares of Class A Common Stock and Class B Common Stock and the
Units will be subject to substantially similar restrictions on transfer,
including rights of first offer and take-along rights, except that prior to the
first underwritten public offering of Units after the Closing Date, the Units
will be subject to certain additional restrictions on transfer, which attempt to
prevent the Parent's being treated as a publicly traded partnership under the
Internal Revenue Code of 1986, as amended. While the shares of Class C Common
Stock are not currently subject to the same restrictions on transfer that are
imposed upon the shares of Class A Common Stock and Class B Common Stock
pursuant to MGI's Certificate of Incorporation, all of the outstanding shares of
Class C Common Stock are subject to substantial restrictions on transfer as a
result of the terms of the management stock subscription agreements between MGI
and each of the holders of such shares, and these restrictions, including
certain MGI and C&D Fund IV repurchase rights in the event of the termination of
the applicable holder's employment with MGI, will continue to apply to the Units
that are issued upon conversion of the shares of Class C Common Stock in the
Merger. In addition, such Units will be subject to the same restrictions on
transfer imposed on all Units pursuant to the LLC Agreement. Holders of MGI
Common Stock and holders of Units also will be entitled to substantially similar
participation and registration rights.

         In addition, though not generally required by law, the LLC Agreement
will impose certain fiduciary duties of care and loyalty on the Members,
Directors and Officers of the Parent that will generally be the same as those of
a stockholder, director or officer of a Delaware corporation, except that no
Member or Director of the Parent who is not also an employee of the Parent or
any of its subsidiaries will be required to present any particular investment
opportunity to the Parent even if such opportunity is of a character that, if
presented to the Parent, could be taken by the Parent.

         Reasons for the Merger and Exchange.

         Benefits to the Combined Companies. The Board of Directors of MGI and
the management of CERA believe that the Merger and the Exchange will better
position the combined companies to compete with larger information providers in
the global marketplace served by both companies, by creating an organization
with the critical mass and resources necessary to sustain rapid growth and
through the development of world-wide name recognition for the combined
companies that may further enhance the reputation of the individual businesses.
The transactions may also improve the ability of the combined companies to
access the financial and equity markets as a larger, more diversified and
credit-worthy entity. The Transactions will also present each company with
opportunities to further expand their respective worldwide client bases through
the cross-marketing of services and the leveraging of each company's familiarity
with and expertise in specific markets. In addition, through the planned
introduction of management at the Parent level to focus on and guide the
strategic development of MGI's and CERA's respective businesses, the companies
anticipate that they will be in a better position to manage their growth and
drive expansion and acquisition initiatives.

         Benefits to MGI. The Board of Directors of MGI believes the Merger and
the Exchange, and the other transactions contemplated by the Merger Agreement,
will position MGI to serve new markets and develop new products. In particular,
MGI believes that affiliation with CERA will present MGI with opportunities to
develop and offer electronically delivered information services, similar to the
electronically delivered services currently provided by MGI, to existing CERA
clients within a variety of energy industries, such as the electricity industry.

         Benefits to CERA. Management of CERA believes the Merger and the
Exchange, and the other transactions contemplated by the Merger Agreement, will
provide CERA with access to sophisticated electronic distribution and delivery
technology and methods and will enable CERA to meet the expanding needs of its
clients by bringing together CERA's experience and expertise in the energy
business with MCM's knowledge of economic and financial markets.

         Operation of MGI and CERA Following the Merger and the Exchange.
Following the Closing, MGI and CERA will each be wholly owned subsidiaries of
the Parent and will continue to be operated as separate though affiliated
businesses. As a result, although certain corporate services or assets (such as
leased premises outside of the United States) may be shared following the
Closing Date, it is not expected that significant cost savings from the
integration or elimination of overlapping operations will be realized from the
Merger and the Exchange. Instead, the success of the Transactions will be
dependent largely upon each company's ability to derive benefits from its
affiliation with the other company and from the additional managerial attention
at the Parent level that will be provided following the consummation of the
Transactions. While the future operating results of MGI or CERA could be
adversely affected by any significant diversion of attention by the applicable
company's management to the development or operation of the businesses of the
other company, the Parent intends to engage a chief executive officer at the
Parent level following the Closing Date, who will be responsible for, among
other matters, coordinating activities between the two companies. In addition,
the Parent expects that in order to finance the CERA Distribution Loan, to pay
certain fees and expenses relating to the Transactions and, following the
consummation of the Transactions, to fund MGI's and CERA's working capital needs
and other business requirements, including in respect of any future business
acquisitions, MCM will incur indebtedness under the Credit Agreement. While the
incurrence of such indebtedness will cause MGI to become more leveraged, MGI's
management believes that MGI will have sufficient cash flow to meet its
obligations, including payments under the Credit Agreement. See "The Merger and
the Exchange -- The Financing." Although there can be no assurance that the
potential benefits of the Transactions will be either partially or fully
realized, a failure to achieve these benefits would be unlikely to have a
material adverse impact on the financial position or results of operations of
either company.

         Governing Law and Management After the Merger and the Exchange.

         After the Merger and the Exchange, MGI shall continue to be governed by
the laws of the State of Delaware, and CERA shall continue to be governed by the
laws of the Commonwealth of Massachusetts. MCM's existence will not be affected
by the Merger and the Exchange. Alberto Cribiore, Gordon McMahon, Donald Gogel,
David Nixon, Daniel Yergin, Joseph Stanislaw and up to seven additional
directors will be named to the Board of Directors of the Parent at the time of
or shortly after the consummation of the Merger and the Exchange. In addition,
Messrs. Cribiore and Yergin will be appointed Chairman and Vice-Chairman of the
Parent, respectively. The LLC Agreement provides for an executive committee of
the Board of Directors of the Parent which, during the intervals between
meetings of the Board, generally will have the powers and authority of the Board
in the management of the Parent. Upon consummation of the Merger and the
Exchange, such executive committee shall be composed of Messrs. Cribiore,
Yergin, Nixon and such other directors as may be designated by the Board. The
persons named as directors of the Parent will also be required to be named as
the directors of CERA and MGI.

         Upon completion of the transactions contemplated by the Merger
Agreement, C&D Fund IV will beneficially own approximately 57% of the then
outstanding Units (or approximately 40% on a fully diluted basis assuming the
grant of the CERA Contingent Units, Goldman Contingent Units and CERA Employee
Contingent Units, and the exercise of all outstanding options (whether vested or
unvested and including all Contingent Options)). In addition, the present
executive officers and directors of CERA and of MGI (including those directors
and executive officers of CERA (and affiliated trusts) and of MGI who are
identified herein as persons who will become directors of the Parent) will own
or control approximately 29% of the outstanding Units (or approximately 36% on a
fully diluted basis assuming the grant of the maximum number of CERA Contingent
Units, Goldman Contingent Units and CERA Employee Contingent Units, and the
exercise of all outstanding options (whether vested or unvested and including
all Contingent Options)). Under the LLC Agreement, the favorable vote of at
least two-thirds of the holders of Units will be required in order to approve
any merger, consolidation, conversion or reorganization of the Parent (other
than certain conversions that will require the approval only of the Board of
Directors of the Parent), the dissolution of the Parent or a sale of all the
capital stock of MGI or CERA. The holders of Units generally will not have any
right to vote on any other action to be taken by the Parent. In addition, until
the first underwritten public offering of Units after the Closing Date, each
holder of Units will be required to vote its Units in favor of the election as
directors of the Parent of two of Messrs. Yergin, Rosenfield and Stanislaw
(collectively "the Founding Stockholders"), three nominees of C&D Fund IV, the
chief executive officer of the Parent, the chief executive officer of MCM and
up to six independent nominees selected by C&D Fund IV with Mr. Yergin's
consent, and the Boards of Directors of MGI and CERA will be required to be
the same as that of the Parent. 

         Conditions to Consummation. 
         Consummation of the Merger and the Exchange is subject to various
conditions, including, among other matters: (i) receipt of all consents and
approvals from governmental authorities necessary to permit consummation of the
Merger and the Exchange; (ii) receipt of all consents and approvals from third
parties, other than consents and approvals, which, if not obtained, would not
have a CERA Material Adverse Effect (as defined below) or a MGI Material Adverse
Effect (as defined below), as the case may be; (iii) the receipt by MCM of funds
sufficient to finance the CERA Distribution Loan; (iv) the absence of any change
since the date of the Merger Agreement that has had or would be reasonably
likely to have a CERA Material Adverse Effect or an MGI Material Adverse Effect,
as the case may be; and (v) satisfaction of certain other conditions. See "The
Merger and the Exchange--Conditions to Obligations of the Parties" and
"--Amendment, Waiver and Termination." The Parent expects that the CERA
Distribution Loan will be financed through MCM's available cash and borrowings
by MCM under the Credit Agreement. See "The Merger and the Exchange--The
Financing."

         Amendment, Waiver and Termination. 

         The Merger Agreement may be terminated at any time prior to the Closing
Date by the written agreement of the Founding Stockholders and MGI. In addition,
the Merger Agreement may be terminated at any time prior to the Closing Date by
MGI, on the one hand, or the Founding Stockholders, on the other hand, by
written notice to the other after 5:00 p.m., New York City time, on December 22,
1997 if the Closing Date shall not have occurred by such date (unless the
failure of the Closing Date to occur shall be due to, in the case of any
termination by MGI, any material breach of the Merger Agreement by MGI, the
Parent or Sub or, in the case of any termination by the Founding Stockholders,
any material breach of the Merger Agreement by the CERA Stockholders or
Goldman), unless such date is extended by the mutual written consent of MGI and
the Founding Stockholders. The Merger Agreement may also be terminated at any
time prior to the Closing Date for certain other reasons. See "The Merger and
the Exchange--Amendment, Waiver and Termination."

         Federal Income Tax Considerations. 

         MGI has received an opinion from Debevoise & Plimpton, special counsel
to MGI, to the effect that, for federal income tax purposes, in general, holders
of MGI Common Stock will not recognize gain or loss upon the receipt of Units in
exchange for MGI Common Stock pursuant to the Merger. See "The Merger and the
Exchange--Federal Income Tax Considerations."

         Procedure for Exchange of Certificates. 

         The Merger Agreement provides that, after the Effective Time, each
holder of a certificate or certificates that, immediately prior to the Merger,
represented shares of MGI Common Stock ("MGI Stock Certificates") who surrenders
such certificate or certificates, together with a completed and signed MGI
Holder Information Form (a copy of which has been enclosed with this Information
Statement/Prospectus), to the person or entity appointed by the Parent (the
"Exchange Agent") will be entitled to receive a certificate or certificates
("Unit Certificates") representing the Units into which such shares of MGI
Common Stock shall have been converted in the Merger. The Parent currently
intends to appoint MGI as the Exchange Agent. Substantially all of the MGI Stock
Certificates currently are held by MCM, as bailee (the "MGI Bailee") pursuant to
a Master Bailment Agreement, dated as of August 31, 1996 (the "MGI Bailment
Agreement"), among certain holders of MGI Common Stock and the MGI Bailee. Each
holder of shares of MGI Common Stock who wants the MGI Bailee to surrender such
holder's MGI Stock Certificates to the Exchange Agent on such holder's behalf
must complete, execute and deliver to the MGI Bailee a Holder Information Form
and a Letter of Instruction (a copy of which has been enclosed with this
Information Statement/Prospectus), which will authorize the MGI Bailee to so
surrender the applicable MGI Stock Certificates. Promptly after the receipt of
such documents, the MGI Bailee will deliver the applicable MGI Stock
Certificates and Holder Information Forms to the Exchange Agent.

         Pursuant to the LLC Agreement, all of the Unit Certificates will be
required to be held by the Parent, as bailee (the "Unit Bailee") under a Master
Bailment Agreement, to be dated the Closing Date (the "Unit Bailment
Agreement"), among certain holders of Units and the Unit Bailee. Accordingly,
the Unit Certificates to be issued in the name of those former holders of MGI
Common Stock whose MGI Stock Certificates, together with completed and signed
Holder Information Forms, shall have been surrendered to the Exchange Agent,
shall be delivered to the Unit Bailee in accordance with the Unit Bailment
Agreement. The Unit Bailee will hold such Unit Certificates for safekeeping in a
safe deposit box at a financial institution chosen by the Unit Bailee, and each
such former holder of MGI Common Stock will receive a receipt from the Unit
Bailee for the applicable Unit Certificate and a photocopy of such Certificate.
See "The Limited Liability Company Agreement--The Units--Bailment Agreement."

         Rights of Dissenting Stockholders. 

         Holders of MGI Common Stock are entitled to assert dissenters' rights
under Section 262 of the DGCL with respect to the proposed Merger and, subject
to the consummation of the Merger, to receive the "fair value" of their shares
by complying with the procedures set forth in Section 262 of the DGCL. See "The
Merger and the Exchange--Appraisal Rights" and the text of Section 262 of the
DGCL, a copy of which is attached as Annex C hereto. Holders of Units will not
be entitled to assert dissenters' rights under the Delaware Act or the LLC 
Agreement. 

         Regulatory Matters. 

         Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"), and the rules promulgated thereunder, the Merger and
the Exchange may not be consummated until certain information is provided to the
Federal Trade Commission ("FTC") and to the Antitrust Division of the United
States Department of Justice ("DOJ"), and a thirty-day waiting period is
observed. C&D Fund IV, the ultimate parent entity of MGI, and Daniel H. Yergin,
the ultimate parent entity of CERA, each filed a Notification and Report Form
pursuant to the HSR Act with the DOJ and FTC on August 21, 1997. Early
termination of the waiting period was granted on August 29, 1997. See "The
Merger and the Exchange--Regulatory Matters."


INTERESTS OF CERTAIN PERSONS IN THE MERGER AND THE EXCHANGE; CONFLICTS OF 
INTEREST


                                       17

<PAGE>   20
         MGI.
         Certain directors of MGI have interests in the Merger and the Exchange
that present them with potential conflicts of interest. In connection with the
Merger and the Exchange, Messrs. Cribiore, McMahon and Gogel will continue to be
directors of the Parent, and Mr. Nixon also will be named as a director of the
Parent and will be a member of the executive committee of the Board of Directors
of the Parent. In addition, Mr. Nixon will continue to be the President and
Chief Executive Officer of MGI. Pursuant to his existing employment agreement
with MGI, in his capacity as such President and Chief Executive Officer, Mr.
Nixon will receive in 1998 a base salary of $275,000 and other customary
benefits. 
         CD&R.

         Clayton, Dubilier & Rice, Inc. ("CD&R"), the manager of C&D Fund IV,
provides managerial and financial advisory services to MGI, and, after the
Merger and the Exchange, will also provide such services to CERA, pursuant to a
Consulting Agreement, dated as of August 31, 1996 (as amended, the "Consulting
Agreement"), among CD&R, MGI, MCM and, after the Merger and the Exchange, CERA.
Under the Consulting Agreement, CD&R is entitled to receive an annual fee of
$150,000, together with reimbursement of out-of-pocket expenses. CD&R will not
be paid any additional amounts in respect of the Merger and the Exchange. Mr.
Gogel is President and a principal of CD&R and a general partner of the general
partner of CD&R Fund IV.

         Brera.

         Pursuant to a Services Agreement, dated as of March 31, 1997 (the
"Cribiore Services Agreement"), between CD&R and Brera, in exchange for a fee
equal to the sum of the amount of any management fee paid to CD&R under the
Consulting Agreement (for so long as Mr. Cribiore serves as the Chairman of the
Board of each of MGI and MCM) and certain other amounts, Brera has been
providing the services of Mr. Cribiore to assist CD&R in providing managerial
and financial advisory services pursuant to the Consulting Agreement, among
other matters. Brera has made and may continue to make other employees,
including Mr. McMahon, available to assist Mr. Cribiore in providing such
services. In addition to the assistance provided pursuant to the Cribiore
Services Agreement, Brera has provided financial advisory services to MGI with
respect to the structuring and negotiation of the Merger, the Exchange and
related transactions, including the financing thereof and certain executive
compensation arrangements. The Brera Options will be granted to Brera or its
designees in return for such financial advisory services. Mr. Cribiore is
managing principal of Brera, and Mr. McMahon is a principal of Brera.

         CERA.

         Certain directors and officers of CERA have interests in the Merger and
the Exchange that present them with potential conflicts of interest. Mr. David
Leuschen, a director of CERA until June 1997, is an employee of Goldman. In
connection with the Merger and the Exchange, Messrs. Yergin, Rosenfield,
Stanislaw, Bupp and Aldrich (and affiliated trusts) will each receive Units, a
right to receive CERA Contingent Units, Contingent Options, and a pro rata
portion of the CERA Cash Distribution. In addition, Messrs. Yergin, Rosenfield
and Stanislaw will enter into employment agreements with CERA, pursuant to which
they will receive a base salary of $265,000, $255,000 and $255,000 per year,
respectively, and other customary benefits. Further, Messrs. Yergin and
Stanislaw will become directors of the Parent, effective immediately upon
consummation of the Merger and the Exchange. Finally, Jordan, a director of CERA
until June 1997, will receive the Jordan Options.

         The issuance of the Contingent Units and the exercisability of the
Contingent Options depend solely upon the rate of growth in CERA's revenues (and
not those of the combined companies) from June 30, 1997 to June 30, 2000
(subject to acceleration, in the case of the Contingent Units, on the occurrence
of certain events). See "The Merger and the Exchange -- Structure and Terms of
the Merger and the Exchange -- Terms of the Contingent Units and Contingent
Options." As a result, during the period in which such rate of growth is being
measured, the Founding Stockholders, each of whom will hold rights to receive
Contingent Units and Contingent Options and two of whom will serve as directors
of each of the Parent, MGI and CERA, may make decisions and take actions in
respect of the Parent, MGI and CERA based upon a desire to maximize CERA's
revenue growth instead of a desire to advance the interests of the combined
companies.


                                       18
<PAGE>   21
         Goldman.

         Goldman Sachs & Co. ("Goldman Sachs"), an affiliate of Goldman,
provided financial advisory services to MGI in respect of the transactions
contemplated by the Merger Agreement, for which Goldman Sachs will receive a
fee of $750,000 on the Closing Date. Additionally, Goldman owns a limited
partnership interest in CERA LP which is the subject of the Goldman Exchange
described herein. In the Goldman Exchange, Goldman will receive Units, the
right to receive the Goldman Contingent Units and Contingent Options. In
addition, a portion of the limited partnership interest in CERA LP owned by
Goldman will be purchased by CERA as part of the CERA Cash Distribution for a
purchase price of $2.39 million. CERA and Goldman are also parties to an
agreement, which by its terms expired on October 31, 1997, pursuant to which
CERA provided certain advisory services to Goldman. CERA and Goldman are
currently discussing the terms upon which CERA may provide services to Goldman
in the future. Consistent with standard practices in the investment banking
industry, Goldman Sachs implemented ethical procedures in connection with its
advisory services to MGI, including ensuring that persons assigned to advise
MGI did not include persons who were simultaneously involved in either the
management of Goldman's ownership interest in CERA LP or in the purchase of
advisory services from CERA under the contract referred to above and
appropriately segregating information received in connection with the
Transactions. 

         Jordan.

         Mr. Jordan, a director of CERA until June 1997, was retained by CERA in
1993 to assist CERA in its review of potential strategic partners. In connection
with his engagement, Mr. Jordan assisted CERA by preparing materials to be
delivered to potential strategic partners, consulted with senior management of
CERA, and advised CERA regarding negotiations with third parties. Pursuant to a
consulting agreement, Mr. Jordan received $35,000 in 1996 for such services. In
addition, CERA agreed to pay Mr. Jordan a fee in respect of the transactions
contemplated by the Merger Agreement. In lieu of such payment, Mr. Jordan has
agreed to accept the Jordan Options.

         See "The Merger and The Exchange -- Interests of Certain Persons in The
Merger and The Exchange; Conflicts of Interest" and "Management -- Certain
Relationships and Related Transactions."

ABSENCE OF PUBLIC MARKET FOR UNITS; RESTRICTIONS ON TRANSFER

         The Units issued in the Merger to holders of MGI Common Stock will be
freely transferable under the Securities Act, except for Units issued to a
holder of MGI Common Stock who, for purposes of Rule 145 under the Securities
Act, may be deemed to be an affiliate of MGI as of August 1, 1997, and Units
held by an affiliate of the Parent for purposes of Rule 144 under the Securities
Act. However, there has been no public trading market for Units prior to the
Merger and the Exchange, and it is not expected that there will be a public
market for the Units in the foreseeable future. In addition, transfers of the
Units will be substantially restricted (i) under the LLC Agreement, (ii)
pursuant to grant, subscription and/or option agreements to be executed in
connection with the acquisition of Units or options to acquire Units by certain
employees of or consultants to CERA or MGI and (iii) pursuant to existing
subscription and/or option agreements executed by certain employees of MGI. See
"Risk Factors--No Public Market for Units; Restrictions on Transfer; Illiquid
Investment" and "The Limited Liability Company Agreement--Resales of Units."
The Units also will be subject to a holdback provision, the right of first offer
and "take-along" rights described below in "The Limited Liability Company
Agreement -- Rights of First Offer" and "The Limited Liability Company Agreement
- -- Take-Along Rights" and participation rights set forth in the LLC Agreement. 

         Under Rule 145 under the Securities Act, affiliates of MGI may not sell
Units issued to them in the Merger except pursuant to an effective registration
statement under the Securities Act or other applicable exemption from the
registration requirements of the Securities Act, including (in the case of such
affiliates who are not affiliates of the Parent) pursuant to Rule 145 under the
Securities Act. The provisions of Rule 145 require that, among other things, the
Units be sold in "brokers' transactions" or in transactions directly with a
"market maker." It is unlikely that an affiliate would be able to comply with
the provisions of Rule 145 to effect a resale of Units.

NUMBER OF STOCKHOLDERS AND HOLDERS OF INTERESTS OF CERA LP
         As of December 31, 1997, there were 206 stockholders of record who held
shares of MGI Common Stock, as shown on the records of MGI for such shares. As
of December 31, 1997, there were nine stockholders of record who held shares of
CERA Common Stock, as shown on the records of CERA for such shares.

As of December 31, 1997, there were two holders of record who held partnership
interests in CERA LP, as shown on the records of CERA LP for such partnership
interests.

DISTRIBUTIONS AND DIVIDENDS

         Parent.
 
         It is the policy of the Parent's Board of Directors to retain earnings
to support operations and to finance continued growth of the Parent's and its
subsidiaries' businesses rather than to make distributions, provided, however,
that the Parent will make distributions, to the extent of available cash,
necessary for holders of Units to pay tax liabilities. The Parent has never made
any distributions on its limited liability company interests. The amount of any
future distributions will be determined by the Board of Directors of the Parent
in light of circumstances then existing, including the Parent's growth,
profitability, financial condition, results of operations, and such other
factors as the Board deems relevant. The Parent does not expect to make any
distributions in the foreseeable future, other than distributions to holders of
Units to pay their taxes, as required by the LLC Agreement. See "The Merger and
the Exchange--Federal Income Tax Considerations" and "The Limited Liability
Company Agreement--The Units--Rights to Distributions and Allocations." There
can be no assurance that the Parent will have sufficient available cash to make
such distributions. The Parent is and, following the Merger and the Exchange,
will continue to be a holding company with no substantial business operations,
and, accordingly, the Parent's ability to make any distributions will be limited
by the ability of the Parent's subsidiaries to transfer funds to the Parent in
the form of cash, loans or advances. See "MGI Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "CERA
Management's Discussion and Analysis of Financial Condition and Results of
Operations."

         MGI. 

         It is the policy of MGI's Board of Directors to retain earnings to
support operations and to finance continued growth of MGI's business rather than
to pay dividends. MGI has never declared or paid any cash dividends or
distributions on its capital stock. MGI may transfer funds to the Parent to
enable the Parent to pay its expenses and to enable the Parent to make
distributions to holders of Units, as required by the LLC Agreement. MGI's
ability to declare and pay dividends and to transfer funds to the Parent in the
form of cash, loans or advances is expected to be limited by certain covenants
to be contained in its loan agreements with financial institutions. See "MGI
Management's Discussion and Analysis of Financial Condition and Results of
Operations."

         CERA. 
   
         It has been the policy of CERA's Board of Directors to distribute
substantially all of its earnings in the form of bonuses. Since June 30, 1995,
CERA has not declared or paid any cash dividends or distributions on its capital
stock, other than the CERA Cash Distribution. CERA may transfer funds to the
Parent to enable the Parent to pay its expenses and to enable the Parent to make
distributions to holders of Units, as required by the LLC Agreement. CERA's
ability to declare and pay dividends and to transfer funds to the Parent in the
form of cash, loans or advances is expected to be limited by certain covenants
to be contained in its loan agreements with MCM or with financial institutions.
See "CERA Management's Discussion and Analysis of Financial Condition and
Results of Operations."

                                  RISK FACTORS

         An investment in the Units offered hereby involves a high degree of
risk. The following factors, in addition to the other information contained in
this Information Statement/Prospectus, should be carefully considered by holders
of MGI Common Stock. Certain of the following risk factors apply to MGI and its
business and operations and certain others apply to CERA and its business and
operations. If the Merger and the Exchange are consummated, these risk factors
will apply equally to the Parent, in that following the Merger and the Exchange
the Parent's primary assets will be the equity of MGI and CERA.

RISKS RELATING TO THE OWNERSHIP OF UNITS

         Concentration of Control; Lack of Ability to Influence Company
         --------------------------------------------------------------
         Actions; Certain Conflicts of Interest. 
         ---------------------------------------

         The following table sets forth the expected ownership of the Units upon
consummation of the Merger and the Exchange both on a primary and fully-diluted
basis, including the grant of Units to the CERA Employees and assuming the
exercise of all Contingent Options and options to purchase Units granted to
employees of or consultants to CERA and MGI or to Brera or Jordan (whether
vested or unvested), and the receipt of all CERA Contingent Units, all Goldman
Contingent Units and all CERA Employee Contingent Units:

<PAGE>   24

         Upon completion of the transactions contemplated by the Merger
Agreement, C&D Fund IV will beneficially own approximately 57% of the then
outstanding Units (or approximately 40% on a fully diluted basis assuming the
grant of the CERA Contingent Units, Goldman Contingent Units and CERA Employee
Contingent Units, and the exercise of all outstanding options (whether vested or
unvested and including all Contingent Options)). In addition, the present
executive officers and directors of CERA and of MGI (including those directors
and executive officers of CERA (and affiliated trusts) and of MGI who are
identified herein as persons who will become directors of the Parent) will own
or control approximately 29% of the outstanding Units (or approximately 36% on a
fully diluted basis assuming the grant of the maximum number of CERA Contingent
Units, Goldman Contingent Units and CERA Employee Contingent Units, and the
exercise of all outstanding options (whether vested or unvested and including
all Contingent Options)). Under the LLC Agreement, the favorable vote of at
least two-thirds of the holders of Units will be required in order to approve
any merger, consolidation, conversion or reorganization of the Parent (other
than certain conversions that will require the approval only of the Board of
Directors of the Parent), the dissolution of the Parent or a sale of all the
capital stock of MGI or CERA. The holders of Units generally will not have any
right to vote on any other action to be taken by the Parent. In addition, until
the first underwritten public offering of Units after the Closing Date, each
holder of Units will be required to vote its Units in favor of the election as
directors of the Parent of two of the Founding Stockholders, three nominees of
C&D Fund IV, the chief executive officer of the Parent, the chief executive
officer of MCM and up to six independent nominees selected by C&D Fund IV with
Mr. Yergin's consent, and the Boards of Directors of MGI and CERA will be
required to be the same as that of the Parent. As a result of these LLC
Agreement provisions, the ability of holders of Units (other than C&D Fund IV
and the Founding Stockholders) to influence or affect the Parent's actions will
be severely limited. These provisions may also have the effect of discouraging a
third party from attempting to acquire the Units of such holders, or may limit
the price that a third party would be willing to pay for such Units.

         Certain Conflicts of Interest--MGI 

         Certain persons have interests in the Merger and the Exchange that
present them with potential conflicts of interest. In connection with the Merger
and the Exchange, Messrs. Cribiore, McMahon and Gogel, all of whom are currently
directors of MGI, will continue to be directors of the Parent, and Mr. Nixon
also will be named as a director of the Parent and will be a member of the
executive committee of the Board of Directors of the Parent. In addition, Mr.
Nixon will continue to be the President and Chief Executive Officer of MGI.
Pursuant to his existing employment agreement with MGI, in his capacity as such
President and Chief Executive Officer, Mr. Nixon will receive in 1998 a base
salary of $275,000 and other customary benefits. 

         Certain Conflicts of Interest--CD&R

         CD&R, the manager of C&D Fund IV, provides managerial and financial
advisory services to MGI, and, after the Merger and the Exchange, will also
provide such services to CERA, pursuant to the Consulting Agreement. Under the
Consulting Agreement, CD&R is entitled to receive an annual fee of $150,000,
together with reimbursement of out-of-pocket expenses. CD&R will not be paid any
additional amounts in respect of the Merger and the Exchange. Mr. Gogel is
President and a principal of CD&R and a general partner of the general partner
of C&D Fund IV.

         No Public Market for Units; Restrictions on Transfer; Illiquid 
         --------------------------------------------------------------
         Investment. 
         -----------
         
         Although the Units to be issued in connection with the Merger or upon
exercise of the Brera Options or the Jordan Options (other than Units issued to
"affiliates" of MGI and Units held by "affiliates" of the Parent) will be
freely transferable under the Securities Act, there is no public market for the
Units and it is not expected that there will be a public market for the Units
in the foreseeable future. The Units to be issued to the CERA Stockholders and
Goldman in the Exchange, the Cera Contingent Units, the Goldman Contingent
Units, the Contingent Options and the Units issuable upon exercise of
Contingent Options will not be registered under the Securities Act, or under
any state securities or "blue-sky" laws or foreign securities laws. As a
result, such Units and Contingent Options will be "restricted securities" for
purposes of the federal securities laws and may be resold only in compliance
with the federal and state securities laws governing "restricted securities."
In addition, transfer of Units to be issued in connection with the Merger and
the Exchange and the other transactions contemplated by the Merger Agreement,
including the CERA Contingent Units, the Goldman Contingent Units, the Units
issuable upon exercise of Contingent Options, the Brera Options and the Jordan
Options, will be substantially restricted under the LLC Agreement and other
agreements pursuant to which shares of MGI Common Stock or MGI Employee Options
have been issued or granted to certain employees of MGI or pursuant to which
Units or options to purchase Units will be or may be issued or granted to
certain employees of or consultants to CERA or MGI and other persons. The Units
also will be subject to a holdback provision, the right of first offer and
"take-along" rights described below in "The Limited Liability Company Agreement
- -- Rights of First Offer" and "The Limited Liability Company Agreement --
Take-Along Rights" and participation rights set forth in the LLC Agreement. The
restrictions on transfer could limit the price that certain investors might be
willing to pay in the future for Units, and could have the effect of making it
more difficult for a third party to acquire, or of discouraging a third party
from attempting to acquire, control of the Parent. 

         Effect of Rights of First Offer and "Take-Along" Rights.
         --------------------------------------------------------

         Until the first underwritten public offering of Units after the Closing
Date, C&D Fund IV and the Founding Stockholders, as the holders of more than 5%
of the outstanding Units on the Closing Date, will possess certain rights of
first offer under the LLC Agreement that may have the effect of preventing a
third party from acquiring Units without the consent of C&D Fund IV and the
Founding Stockholders. In addition, under the LLC Agreement, until the first
underwritten public offering of Units after the Closing Date, in the event that
the holders of a majority of the Units desire to sell all of their Units to a
third party, such holders will have the right to require all other holders of
Units to participate in such sale.

         Risks Associated with Ownership of Additional Assets. 
         -----------------------------------------------------

         Upon consummation of the Merger and the Exchange, the Parent will own
two principal assets, its interest in CERA and its interest in MGI. Accordingly,
the Parent's results of operations will be dependent on the successful and
continued operation of both CERA and MGI (instead of MGI only, as is currently
the case). In particular, if either CERA or MGI experiences decreased demand for
its services or increased competition or otherwise suffers a material adverse
change in its business, the Parent's results of operations may be materially
adversely affected.



                                       23
<PAGE>   26
         Certain Conflicts of Interest--Brera
    
         Pursuant to the Cribiore Services Agreement, in exchange for a fee
equal to the sum of the amount of any management fee paid to CD&R under the
Consulting Agreement (for so long as Mr. Cribiore serves as the Chairman of the
Board of each of MGI and MCM) and certain other amounts, Brera has been
providing the services of Mr. Cribiore to assist CD&R in providing managerial
and financial advisory services pursuant to the Consulting Agreement, among
other matters. Brera has made and may continue to make other employees,
including Mr. McMahon, available to assist Mr. Cribiore in providing such
services. In addition to the assistance provided pursuant to the Cribiore
Services Agreement, Brera has provided financial advisory services to MGI with
respect to the structuring and negotiation of the Merger, the Exchange and
related transactions, including the financing thereof and certain executive
compensation arrangements. The Brera Options will be granted to Brera or its
designees in return for such financial advisory services. Mr. Cribiore is
managing principal of Brera, and Mr. McMahon is a principal of Brera.

         Certain Conflicts of Interest--CERA

         Certain directors and officers of CERA also have interests in the
Merger and the Exchange that present them with potential conflicts of interest.
Mr. David Leuschen, a director of CERA until June 1997, is an employee of
Goldman. In connection with the Merger and the Exchange, Messrs. Yergin,
Rosenfield, Stanislaw, Bupp and Aldrich (and affiliated trusts) will each
receive Units, a right to receive CERA Contingent Units, Contingent Options,
and a pro rata portion of the CERA Cash Distribution. In addition, Messrs.
Yergin, Rosenfield and Stanislaw will enter into employment agreements with
CERA, pursuant to which they will receive a base salary of $265,000, $255,000
and $255,000 per year, respectively, and other customary benefits. Further,
Messrs. Yergin and Stanislaw will become directors of the Parent, effective
immediately upon consummation of the Merger and the Exchange. Finally, Jordan,
a director of CERA until June 1997, will receive the Jordan Options.

         The issuance of the Contingent Units and the exercisability of the
Contingent Options depend solely upon the rate of growth in CERA's revenues (and
not those of the combined companies) from June 30, 1997 to June 30, 2000
(subject to acceleration, in the case of the Contingent Units, on the occurrence
of certain events). See "The Merger and the Exchange -- Structure and Terms of
the Merger and the Exchange -- Terms of the Contingent Units and Contingent
Options." As a result, during the period in which such rate of growth is being
measured, the Founding Stockholders, each of whom will hold rights to receive
Contingent Units and Contingent Options and two of whom will serve as directors
of each of the Parent, MGI and CERA, may make decisions and take actions in
respect of the Parent, MGI and CERA based upon a desire to maximize CERA's
revenue growth instead of a desire to advance the interests of the combined
companies.

         Certain Conflicts of Interest--Goldman

         Goldman Sachs, an affiliate of Goldman, provided financial advisory
services to MGI in respect of the transactions contemplated by the Merger
Agreement, for which Goldman Sachs will receive a fee of $750,000 on the
Closing Date. Additionally, Goldman owns a limited partnership interest in CERA
LP which is the subject of the Goldman Exchange described herein. In the
Goldman Exchange, Goldman will receive Units, the right to receive the Goldman
Contingent Units and Contingent Options. In addition, a portion of the limited
partnership interest in CERA LP owned by Goldman will be purchased by CERA as
part of the CERA Cash Distribution for a purchase price of $2.39 million. CERA
and Goldman are also parties to an agreement, which by its terms expired on
October 31, 1997, pursuant to which CERA provided certain advisory services to
Goldman. CERA and Goldman are currently discussing the terms upon which CERA
may provide services to Goldman in the future. Consistent with standard
practices in the investment banking industry, Goldman Sachs implemented ethical
procedures in connection with its advisory services to MGI, including ensuring
that persons assigned to advise MGI did not include persons who were
simultaneously involved in either the management of Goldman's ownership
interest in CERA LP or in the purchase of advisory services from CERA under the
contract referred to above and appropriately segregating information received
in connection with the Transactions.

         Certain Conflicts of Interest--Jordan

         Mr. Jordan, a director of CERA until June 1997, was retained by CERA
in 1993 to assist CERA in its review of potential strategic partners. In
connection with his engagement, Mr. Jordan assisted CERA by preparing materials
to be delivered to potential strategic partners, consulted with senior
management of CERA, and advised CERA regarding negotiations with third parties.
Pursuant to a consulting agreement, Mr. Jordan received $35,000 in 1996 for
such services. In addition, CERA agreed to pay Mr. Jordan a fee in respect of
the transactions contemplated by the Merger Agreement. In lieu of such payment,
Mr. Jordan has agreed to accept the Jordan Options.



                                       24
<PAGE>   27
         Risks Relating to the Merger and the Exchange. 
         ----------------------------------------------

         Consummation of the Merger and the Exchange is subject to various
conditions, including, without limitation, the receipt by MCM of funds
sufficient to finance the CERA Distribution Loan and the absence of any change
since the date of the Merger Agreement that has had or would be reasonably
likely to have a CERA Material Adverse Effect or a MGI Material Adverse Effect,
and there can be no assurance that the Merger and the Exchange will ever be
consummated. See "The Merger and the Exchange--Conditions to Obligations of the
Parties." The success of the Merger and the Exchange will be determined by
various factors, including the ability of each company to derive significant
benefits from its affiliation with the other company and from the additional
managerial attention at the Parent level that will be provided following the
consummation of the Transactions. See "Summary -- The Merger and the Exchange -
- - Reasons for the Merger and the Exchange." While the future operating results
of MGI or CERA could be adversely affected by any significant diversion of
attention by the applicable company's management to the development or operation
of the businesses of the other company, the Parent intends to engage a chief
executive officer at the Parent level following the Closing Date, who will be
responsible for, among other matters, coordinating activities between the two
companies.

         Risks Associated With Changes in Shareholder Rights.
         ----------------------------------------------------
 
         The rights of the holders of Units will be subject to, and may be
adversely affected by, certain requirements not currently imposed upon holders
of MGI Common Stock, such as requirements with respect to the election of
directors, the vote required in order to authorize certain actions to be taken
by the Parent and the parties whose consent will be required in order to amend
particular provisions of the LLC Agreement. See " -- Concentration of Control;
Lack of Ability to Influence Company Actions; Certain Conflicts of Interest" and
"Comparison of Stockholder and Unit Holder Rights." The existence of such
requirements, while providing for desirable efficiency in connection with
Parent's operations and for other corporate purposes, may make it more difficult
for a holder of Units (other than C&D Fund IV) to influence or affect the
Parent's actions. However, because C&D Fund IV holds over 80% of the outstanding
shares of MGI Common Stock, other holders of MGI Common Stock currently do not
have a significant ability to influence or affect MGI's actions. See "Comparison
of Stockholder and Unit Holder Rights" and "The Limited Liability Company
Agreement."

         Dilution. 
         ---------
 
         The Units will be subject to dilution upon future issuances of Units,
including any issuance of Units upon the exercise of options under the CERA
Option Plan and the MCM Group, Inc. LLC Unit Option Plan (the "MGI Option
Plan"), any issuance of CERA Contingent Units, any issuance of Goldman
Contingent Units, any issuance of CERA Employee Contingent Units and any
issuance of Units upon the exercise of Contingent Options, Existing MGI Options,
the Brera Options or the Jordan Options. On or prior to the Closing Date, CERA
will adopt the CERA Option Plan and MGI will adopt the MGI Option Plan, pursuant
to which options to purchase an aggregate of up to 462,699 Units may be granted.
In connection with the Merger and the Exchange, Existing MGI Options will
automatically be converted into options to purchase an aggregate of 867,912
Units. Shortly following the Merger and the Exchange, options to purchase an
aggregate of 231,500 Units will be granted by CERA under the CERA Option Plan to
certain employees of or consultants to CERA. In connection with the Merger and
the Exchange, CERA will grant to the CERA Stockholders and to Goldman,
Contingent Options to purchase an aggregate of 98,744 Units, based on the
attainment by CERA of certain revenue growth rates. The Merger Agreement also
provides that if CERA achieves certain revenue growth rates, the CERA
Stockholders will receive an aggregate of from 119,704 additional Units to
707,661 additional Units, Goldman will receive from 14,444 additional Units to
85,389 additional Units and the CERA Employees will receive an aggregate from
10,291 additional Units to 60,840 additional Units. Additionally, in connection
with the Merger and the Exchange, Brera will receive options to purchase an
aggregate of 33,444 Units and Jordan will receive options to purchase 11,132
Units. See "Interests of Certain Persons in the Merger and the Exchange;
Conflicts of Interest," "Concentration of Control; Lack of Ability to Influence
Company Actions; Certain Conflicts of Interest," and "The Merger and the
Exchange--Structure and Terms of the Merger and the Exchange."

<PAGE>   28
         Dividend Policy; Inability to Declare Dividends. 
         ------------------------------------------------

         The Parent does not expect to declare or pay any dividends or
distributions in the foreseeable future, other than distributions to holders of
Units to pay their taxes, as required by the LLC Agreement. The Parent's ability
to declare and pay dividends or distributions is limited by the ability of the
Parent's subsidiaries to transfer funds to the Parent in the form of cash, loans
or advances. It is expected that MGI's and CERA's ability to transfer funds to
the Parent will be limited by certain covenants to be contained in their
respective loan agreements. The inability of MGI and CERA to transfer funds to
the Parent in the form of cash, loans or advances may prevent the Parent from
making the distributions required by the LLC Agreement.

         Fraudulent Conveyance Considerations.
         -------------------------------------

         In connection with the CERA Distribution Loan, MCM will incur (and the
Parent and MGI will guarantee the incurrence of) substantial indebtedness under
the Credit Agreement. MCM will then make the CERA Distribution Loan to CERA and
CERA will apply a portion of such funds, together with CERA's available cash, to
the extent necessary, to make a distribution to the CERA Stockholders and will
apply the remainder of such funds and available cash to purchase a portion of
the limited partnership interest in CERA LP held by Goldman.

         If, under relevant federal or state fraudulent conveyance statutes in a
bankruptcy, reorganization or rehabilitation case or similar proceeding or a
lawsuit by or on behalf of unpaid creditors of CERA, a court were to find that,
at the time that CERA incurred the indebtedness under the CERA Distribution Loan
in order to make the CERA Cash Distribution: (i) CERA incurred such indebtedness
and made the CERA Cash Distribution with the intent of hindering, delaying or
defrauding current or future creditors; or (ii) (A) CERA received less than
reasonably equivalent value or fair consideration for incurring such
indebtedness and (B) CERA (w) was insolvent or was rendered insolvent by reason
of the Transactions and/or such incurrence of indebtedness, (x) was engaged, or
was about to engage, in a business, transaction or distribution for which its
assets constituted unreasonably small capital, (y) intended to incur, or
believed that it would incur, debts beyond its ability to pay such debts as they
matured or (z) was a defendant in an action for money damages, or had a judgment
for money damages docketed against it (if, in either case, after final judgment
the judgment is unsatisfied), such court could (1) find that the CERA Cash
Distribution constituted a fraudulent transfer or conveyance, void it and
require that the CERA Stockholders and Goldman return the CERA Cash Distribution
to a fund for the benefit of the creditors of CERA, and (2) avoid or subordinate
the indebtedness of CERA under the CERA Distribution Loan to other presently
existing and future indebtedness of CERA.

         In addition, having concluded that CERA was insolvent and having voided
the CERA Distribution Loan, if, under relevant federal or state fraudulent
conveyance statutes in a bankruptcy, reorganization or rehabilitation case or
similar proceeding or a lawsuit by or on behalf of unpaid creditors of MCM, a
court were to find that, at the time MCM incurred the indebtedness under the
Credit Agreement to finance the CERA Distribution Loan, (i) MCM incurred the
indebtedness with the intent of hindering, delaying or defrauding current or
future creditors; or (ii)(A) MCM received less than reasonably equivalent value
or fair consideration for incurring such indebtedness and (B) MCM (w) was
insolvent or was rendered insolvent by reason of the Transactions and/or such
incurrence of indebtedness, (x) was engaged, or was about to engage, in a
business, transaction or distribution for which its assets constituted
unreasonably small capital, (y) intended to incur, or believed that it would
incur, debts beyond its ability to pay such debts as they matured or (z) was a
defendant in an action for money damages, or had a judgment for money damages
docketed against it (if, in either case, after final judgment the judgment is
unsatisfied), such court could find that the CERA Distribution Loan constituted
a fraudulent transfer or conveyance as to MCM's creditors and that the Parent
was an entity for whose benefit the transfer or conveyance was made, in which
event MCM could become entitled to recover the value of the CERA Distribution
Loan from the Parent for the benefit of creditors of MCM.

<PAGE>   29
         The measure of insolvency for purposes of the foregoing will vary
depending upon the law of the jurisdiction which is being applied. Generally,
however, CERA or MCM, as the case may be, would be considered insolvent if, at
the time that the indebtedness is incurred by CERA under the CERA Distribution
Loan or by MCM under the Credit Agreement, as the case may be, either (i) the
fair market value (or fair saleable value) of its assets is less than the amount
required to pay the probable liability on its total existing debts and
liabilities (including contingent liabilities) as they become absolute and
matured or (ii) it is incurring debt beyond its ability to pay as such debt
matures. No assurance can be given as to what method a court would use in order
to determine whether CERA or MCM, as the case may be, was "insolvent" at the
time of the incurrence of such indebtedness or that, regardless of the method of
valuation, a court would not determine that CERA or MCM, as the case may be, was
insolvent at that time. The avoidance of the CERA Cash Distribution to the CERA
Stockholders and Goldman as described above could result in the CERA
Stockholders and Goldman being required to return all or a portion of the CERA
Cash Distribution received by them, and the characterization of the CERA
Distribution Loan as a fraudulent conveyance as to MCM as described above could
result in the Parent being required to return to MCM the value of the CERA
Distribution Loan.

         With respect to CERA, CERA's management believes that at the time CERA
incurs indebtedness under the CERA Distribution Loan, and with respect to MCM,
MCM's management believes that at the time MCM incurs indebtedness under the
Credit Agreement to finance the CERA Distribution Loan, CERA or MCM, as the case
may be, (i) will be (A) neither insolvent nor rendered insolvent thereby, (B) in
possession of sufficient capital to run its business effectively and (C)
incurring debts within its ability to pay as the same mature or become due and
(ii) will have sufficient assets to satisfy any probable money judgment against
it in any pending action. In reaching the foregoing conclusions, CERA has
relied, in part, upon the fact that prior to June 30, 2000, CERA will be
required to make cash payments in respect of principal or interest under the
CERA Distribution Loan only to the extent required by the board of directors of
the Parent. There can be no assurance, however, that a court passing on such
questions would reach the same conclusions.


         Federal Income Tax Risks. 
         -------------------------
 
         The Parent is expected to be classified as a partnership for federal
income tax purposes. As such, the Parent will not be subject to federal income
tax. Instead, each holder of Units will be required to include its allocable
share of the Parent's items of income, gain, loss, deduction and credit in
computing the Unit holder's own taxable income for federal income tax purposes.
Accordingly, a Unit holder may be required to pay federal income tax on its
allocable share of the Parent's income for a year even though no distributions
are made to the Unit holder with respect to such income. The LLC Agreement
requires that the Parent make distributions, to the extent of available cash, to
Unit holders in order to pay their taxes. However, there can be no assurance
that the Parent will have sufficient available cash to make distributions in the
full amount of the Unit holders' tax liabilities. Because a Unit holder's tax
liability may exceed the cash distributed to it from the Parent in a particular
period, a Unit holder may be required to satisfy such tax liability from other 
sources. See "The Merger and the Exchange--Federal Income Tax Considerations."


                                      27
<PAGE>   30
         The Parent will be classified as a partnership for federal income tax
purposes unless it is treated as a "publicly traded partnership". Although it
is not expected that the Parent will be treated as a publicly traded
partnership, because determination of such status will depend in large part
upon facts existing in the future, there can be no assurance that such
characterization will not occur, and Debevoise & Plimpton, special counsel to
MGI, cannot provide an opinion on this issue. If the Parent were treated as a
publicly traded partnership, it would be classified as an association taxable
as a corporation for federal income tax purposes. As a result, the Parent would
be subject to federal income tax at the rates applicable to corporations, and
the Parent's items of income, gain, loss, deduction and credit would be
reflected only on its own tax return. The holders of Units would not be
required to take such items into account in computing the holders' own taxable
income. Instead, the holders of Units would be taxable in the same manner as
shareholders of a corporation. In general, a holder of Units receiving a
distribution from the Parent would recognize ordinary dividend income to the
extent of the Parent's current and accumulated earnings and profits. The
imposition of tax on the Parent would reduce the amount of distributions that
could be made to the holders of Units. See "The Merger and the
Exchange--Federal Income Tax Considerations."

         Liability for Certain Distributions.
         ------------------------------------

         The members of the Parent generally will not be obligated personally
for any of the debts, obligations or liabilities of the Parent, whether arising
in contract, tort or otherwise, solely by reason of being a member of the
Parent. A member who receives a distribution from the Parent, however, at a time
when, after giving effect to the distribution, the liabilities of the Parent
(other than certain liabilities specified in the Delaware Act) exceed the fair
value of the assets of the Parent will be liable to the Parent for the amount
of such distribution if such member knows at the time such distribution is made
that such liabilities then exceed the fair value of such assets.

RISKS RELATING TO CERA

         Dependence on Renewals of Retainer-Based Research Services. 
         ----------------------------------------------------------

         CERA's success depends in part upon renewals of subscriptions for its
research products. Approximately 50% and 53% of CERA's revenues for the years
ended June 30, 1996 and 1997, respectively, were derived from CERA's
subscription-based research products. CERA has historically experienced high
subscription renewal rates for these products. However, there can be no
assurance that CERA will be able to sustain such high renewal rates. A
significant portion of the growth of CERA's consulting and advisory services in
any given year has historically been generated in the last quarter of the fiscal
year. Accordingly, any deterioration in CERA's ability to generate revenue
growth might not be apparent until late in CERA's fiscal year. A decline in
renewal rates for CERA's research products or a decline in demand for consulting
and advisory services could have a material adverse effect on CERA's business,
financial condition, and results of operations.

         Dependence on Limited Number of Customers. 
         -----------------------------------------

         CERA's revenues during a given fiscal year are typically dependent in
part on certain significant customers who, in the aggregate, accounted for
approximately 28% and 20% of its total revenues for the years ended June 30,
1996 and 1997, respectively. Historically, CERA has been able to replace the
loss of such customers. The inability to replace these customers could
materially and adversely affect the financial performance of CERA.

         Potential Fluctuations in Operating Results. 
         -------------------------------------------

         CERA's operating results have fluctuated in the past and may fluctuate
significantly in the future due to various factors, including the level and
timing of renewals of subscriptions to CERA's services, the timing and amount of
new business generated by CERA, the timing of revenue-generating events
sponsored by CERA, the mix of domestic versus international business, the
development, introduction and marketing of new products and services, the hiring
and training of research analysts and sales personnel, the utilization of its
advisory services, changes in the spending patterns of CERA's target clients,
CERA's accounts receivable collection experience, changes in market demand for
energy research and analysis and competitive conditions in the energy industry.
Due to these factors, CERA believes period-to-period comparisons of results of
operations are not necessarily meaningful and should not be relied upon as an
indication of future results of operations.

         Risks Associated with Loss of Key Personnel. 
         -------------------------------------------

         CERA's ability to conduct and expand its business is related to its
ability to hire and retain the highly qualified personnel needed to maintain and
enhance the presentation, quality and breadth of coverage of CERA's research and
applications. CERA's key assets are the product line research directors and
research analysts who are responsible for the compilation, analysis and
dissemination of CERA's research and application services. A loss of key
personnel, particularly Daniel Yergin, CERA's founder and President, James
Rosenfield, a Managing Director and Head of Business Development, Joseph
Stanislaw, a Managing Director and Head of Global Research, Philippe A.
Michelon, Managing Director, Operations, and the research directors for major
product lines, could have a material adverse effect on CERA. In connection with
the Merger and the Exchange, Messrs. Yergin, Rosenfield and Stanislaw will enter
into new employment agreements with CERA. See "Management--Employment
Agreements.


                                       29
<PAGE>   32
         Need to Attract and Retain Professional Staff. 
         ---------------------------------------------

         CERA's future success will depend in large measure upon the continued
contributions of its senior management team, research analysts, and experienced
sales and marketing personnel. Accordingly, future operating results will be
largely dependent upon CERA's ability to retain the services of these
individuals and to attract additional qualified personnel from a limited pool of
qualified candidates. CERA experiences intense competition in hiring and
retaining professional personnel from, among others, other research firms,
management consulting firms, and financial services companies. Many of these
firms have substantially greater financial resources than CERA to attract and
compensate qualified personnel. The loss of the services of key management and
professional personnel or the inability to attract such personnel could have a
material adverse effect on the CERA's business, financial condition, and results
of operations.

         International Operations; Political and Economic Conditions in Foreign
         ----------------------------------------------------------------------
         Jurisdictions.
         -------------

         Revenues attributable to customers outside the United States
represented approximately 30% and 33% of CERA's total revenues for the years
ended June 30, 1996 and 1997, respectively. CERA expects that international
revenues will continue to account for a substantial portion of total revenues
and intends to continue to expand its international operations. Expansion into
new geographic territories requires considerable management and financial
resources and may negatively impact CERA's near-term results of operations. In
addition, CERA's operating results are subject to the risks inherent in
international sales, including political and economic conditions in various
jurisdictions, tariffs and other barriers, longer accounts receivable collection
cycles, difficulties in protecting intellectual property rights in international
jurisdictions, changes in market demand as a result of exchange rate
fluctuations, difficulties in staffing and managing foreign sales operations,
and higher levels of taxation on foreign income than domestic income. There can
be no assurance that such factors will not have a material adverse effect on
CERA's business, financial condition, and results of operations.

         Cyclical Industry Customer Base; Fluctuation of Revenues and Earnings. 
         ---------------------------------------------------------------------

         CERA's research products and services target customers in the global
energy market. CERA's ability to attract and retain customers in this market is
dependent on risks inherent in the global energy market. A decline in energy
price volatility could result in reduced demand for CERA's products and
services. Many of the end users of CERA's products typically experience cyclical
fluctuations in revenues and earnings. Accordingly, there can be no assurance
that CERA will not experience declining revenues in the future.

         Competition; Pricing Pressure; Loss of Market Share. 
         ---------------------------------------------------

         CERA competes in the market for research products and services with
other independent providers of similar services including Petroleum Economics
Limited, Petroleum Finance Company and PIRA Energy Group. Some of CERA's
competitors have substantially greater financial, information-gathering, and
marketing resources than CERA. In addition, CERA's indirect competitors include
other information providers such as electronic and print publishing companies,
survey-based general market research firms, brokerage firms and general business
consulting firms. CERA's indirect competitors may choose to compete directly
against CERA in the future. In addition, there are relatively few barriers to
entry into CERA's market and new competitors could readily seek to compete
against CERA in one or more market segments addressed by CERA's products and
services. Increased competition could adversely affect CERA's operating results
through pricing pressure and loss of market share. There can be no assurance
that CERA will be able to continue to compete successfully against existing or
new competitors.

<PAGE>   33

         Management of Growth; Lack of Technology Infrastructure. 
         -------------------------------------------------------

         Since inception, CERA has experienced substantial changes in its
operations as a result of the expansion and growth of CERA's business, which
have placed significant demands on CERA's management, administrative,
operational and financial resources. CERA's ability to manage growth, should it
continue to occur, will require CERA to continue to implement and improve its
operational, financial and management information systems and to motivate and
effectively manage an evolving workforce. If CERA's management is unable to
effectively manage a changing and growing business, the quality of CERA's
products, its ability to retain key personnel and its results of operations
could be materially adversely affected.

         Management of Planned Expansion. 
         -------------------------------

         Any significant expansion by CERA is expected to place a strain on
CERA's financial, operational and managerial resources. To manage its expansion,
CERA must continue to implement and improve its operations and financial systems
and to increase, train and manage its personnel. There can be no assurance that
CERA's systems, procedures or controls currently in place will be adequate to
support CERA's operations or that CERA will be able to implement additional
systems successfully and in a timely manner if required. If CERA continues to
grow, it will be required to expand its research staff, expand its sales and
marketing force, recruit additional key management personnel, improve its
operational and financial systems and train, motivate and manage additional
employees. There can be no assurance that CERA will be able to manage these
changes successfully. Any inability of CERA to manage its growth successfully
could have a material adverse effect on CERA's business, financial condition and
results of operations.

         Risks Associated With New Product Development. 
         ----------------------------------------------

         CERA's future success will depend in part on its ability to develop or
acquire new products and services that address specific industry and business
organization sectors, changes in client requirements and technological changes
in the energy industry. The process of internally researching, developing,
launching and gaining client acceptance of a new product or service, or
assimilating and marketing an acquired product or service, is inherently risky
and costly. There can be no assurance that its efforts to introduce new, or
assimilate acquired, products or services, will be successful.

         Pricing Strategy; Limitation on Potential CERA Market
         -----------------------------------------------------
 
         CERA's pricing strategy, like those of its competitors, may limit the
potential market for CERA's services to substantial commercial and governmental
users of its research products and applications and consulting services. As a
result, CERA may be required to reduce prices for its services or to introduce
new products with lower prices in order to expand its market share. These
actions could have a material adverse effect on CERA's business and results of
operations.

         Uncertainties Relating to Proprietary Rights. 
         ---------------------------------------------

         CERA's success and ability to compete is dependent in part upon its
proprietary information and technology. CERA relies on a combination of
copyright, trademark and trade secret laws, employee and third-party
nondisclosure agreements and contractual provisions and other methods to protect
its proprietary information and technology. There can be no assurance that the
measures taken by CERA to protect its proprietary information and technology
will be adequate to prevent misappropriation or that others will not develop
independently similar proprietary information or technology. Furthermore, there
can be no assurance that competitors will not develop similar or superior
proprietary information or technologies.

         CERA licenses certain content from third parties. There can be no 
assurance CERA will not be involved in expensive and time consuming litigation
with respect to claims based on the third-party content that it distributes. Any
such litigation, whether or not resulting in a ruling requiring the payment of
damages, could have a material adverse effect on CERA's business, financial
condition and results of operations.

RISKS RELATING TO MGI

         Risks Relating to MGI's Industry and Competition.
         ------------------------------------------------
         
         MGI competes in the high-value-added segment of the financial
information services industry against both well-established and smaller
companies, some of which may have substantially greater resources than MGI and
offer a broader array of services. Currently, MGI's primary competitors are MMS
International, owned by McGraw-Hill, and Technical Data Corporation, owned by
Thomson Corporation and a strategic partner of Dow Jones Markets, Inc. (formerly
known as Dow Jones Telerate, Inc., "DJM"). MGI distributes almost all of its
services through screens provided by DJM, Bloomberg L.P. ("Bloomberg"), Bridge
Information Systems, Inc. (formerly known as Knight-Ridder Financial, Inc.,
"Bridge"), Reuters Limited ("Reuters"), ADP Financial Information Services, Inc.
("ADP") and Kabushiki Kaisha Quick ("Quick") (collectively, the "Vendor
Distribution Firms"). Ongoing access by MGI to the Vendor Distribution Firms is
critical to future performance.

         Competition is based on various factors, including the breadth of
coverage, availability of both fundamental and technical analyses, the frequency
and number of intra-day updates, the range, quality, timeliness and accuracy of
information, the ability to filter, retrieve, manipulate and store information,
the level of fees charged, customer service, the success of marketing and sales
efforts and the subscribers' preference among the Vendor Distribution Firms.
Currently, there are relatively few barriers to entry by new on-line service
providers, although the lack of name recognition and access to the distribution
network provided by the Vendor Distribution Firms may make entering the business
more difficult for potential competitors. The Vendor Distribution Firms also
distribute numerous competing services, including their own or their affiliates'
proprietary services and the services offered by MGI's primary competitors.

         Competition is expected to increase as technological advancements
improve the speed and reliability of delivery and retrieval of information
supplied over the Internet, which could emerge as an inexpensive distribution
alternative to the high-cost, proprietary networks offered by the Vendor
Distribution Firms. At present, the relatively slow rate of transmission of data
over the Internet, questions about the reliability of Internet service
providers' systems and concerns over the security and integrity of data
delivered over the Internet serve as technological impediments to the
effectiveness of the Internet as a distribution channel for services such as
those provided by MGI. If technological advancements enabling faster, more
reliable and secure delivery of digital data occur, the Internet could emerge as
a significant distribution channel for financial information, including
high-value-added services such as those provided by MGI. Because access to the
Internet is inexpensive and requires relatively inexpensive equipment and
software, such technological advancements could allow the Internet to emerge as
an alternative to the Vendor Distribution Firms and therefore reduce one of the
most significant entry barriers to start-up--i.e., access to the Vendor
Distribution Firms. While MGI is taking steps to respond to developments in
Internet- related technologies and industries, there can be no assurance that
increased competition resulting from the emergence of the Internet as an
effective, low-cost distribution channel would not have a material adverse
effect on MGI. See "Business of MGI--Competition."

         Effect of Changes in Economic or Market Conditions on Demand for
         ----------------------------------------------------------------
         Services. 
         ---------
         
         Changes in economic and market conditions may adversely affect the
demand for MGI's services and, therefore, revenue and profitability. Virtually
all of MGI's revenue is derived from subscriptions, and the subscribers of MGI's
services are primarily the trading and sales desks of institutional participants
in the global financial markets. Consequently, a significant decrease in the
volume of activity in the global financial markets resulting from general


                                       32
<PAGE>   35
economic factors or a decrease in the number of trading and sales desks in such
institutional participants could affect materially the level of demand for MGI's
services, which in turn could lead to termination of subscriptions representing
a material portion of MGI's revenues.

         Risks Associated with Loss of Key Personnel. 
         -------------------------------------------

         MGI's ability to conduct and expand its business is related to its
ability to hire and retain the highly qualified personnel needed to maintain and
enhance the presentation, quality and breadth of coverage of MGI's research
services. MGI's key assets are the economists, market analysts and technical
analysts who are responsible for the compilation, analysis and dissemination of
MGI's financial information services on a daily, real-time basis. A loss of key
personnel, particularly David D. Nixon, the President and Chief Executive
Officer of MGI, Malcolm Cook, Anthony Napolitano and Lauretta Gell, each a
Senior Vice President of MGI, and the senior analysts and managers responsible
for MGI's major product lines, could have a material adverse effect on MGI. Each
of Messrs. Nixon, Cook and Napolitano and Ms. Gell have entered into employment
agreements with MGI. See "Management--Employment Agreements."

         Dependence on Technology; Third Party Proprietary Software
         ----------------------------------------------------------
         Applications.
         -------------

         MGI depends on computer equipment and software technology to provide
its services to its customers. MGI must continue to maintain and upgrade its
equipment and software to remain competitive, adapt to technological
developments in the distribution and presentation of electronic financial
information and ensure the quality, delivery, timeliness and accuracy of its
services. Generally, MGI's economists and analysts in its various offices
prepare and transmit information and analyses over MGI's wide area network to
MGI's central computer processing and data storage center in New York (the "Data
Center"), which packages that information in specific presentation formats and
sends the final products to the Vendor Distribution Firms virtually
instantaneously, which is a critical factor in providing real-time financial
information. There can be no assurance that physical damage or other disruption
to the Data Center through fire, flood or other event outside the control of MGI
would not have a material adverse effect on MGI.

         The Data Center runs on an operating system that uses, among other
software, certain source codes and proprietary software applications (the
"Licensed Software") originally developed by Key Information Systems, Inc.
("KIS") and licensed exclusively to MGI. MGI and KIS have entered into
agreements covering the provision of services relating to the Data Center and
the Licensed Software and certain option rights of MGI with respect to the
Licensed Software. The services agreement between MGI and KIS will expire on
December 31, 1997, and, after such date, such agreement may be terminated by
either party upon 90 days' prior notice. MGI may replace the operating system
for its Data Center and develop or procure new software applications to run on
the new system. If MGI does not replace its existing operating system and the
service agreement between KIS and MGI were to be terminated by KIS or KIS were
not otherwise available to perform its duties under the service agreement, MGI
would be required to secure a replacement vendor to perform such duties or
acquire some other means of maintaining MGI's Data Center. There can be no
assurance that an adequate replacement vendor could be timely located by MGI or
that the termination of such service agreement would not have a material adverse
effect on MGI's business.

<PAGE>   36
         Risks Associated With New Product Development. 
         ---------------------------------------------

         MGI's future success will depend in part on its ability to develop or
acquire new products and services that address specific industry and business
organization sectors, changes in client requirements and technological changes
in the financial markets. The process of internally researching, developing,
launching and gaining client acceptance of a new product or service, or
assimilating and marketing an acquired product or service, is inherently risky
and costly. There can be no assurance that its efforts to introduce new, or
assimilate acquired, products or services, will be successful.

         Termination Provisions of Subscription Agreements. 
         -------------------------------------------------

         Virtually all of MGI's revenues are derived from subscription
agreements with its customers. Subscription agreements with U.S.-based customers
are generally made directly between those customers and MGI and may be either
oral or written agreements. Oral agreements with U.S.-based clients are
generally terminable upon ninety (90) days' notice without penalty. Written
agreements, which represented approximately 18.7% of MGI's U.S. revenues in
1996, typically have a one-year term but are not subject to early termination.

         Non-U.S.-based clients subscribe by means of service agreements entered
into with the Vendor Distribution Firms, pursuant to which a subscriber can
elect to subscribe for various optional services, including MGI's services. With
certain exceptions, such agreements are written and typically have one- or
two-year terms that renew automatically unless the subscriber provides 90 days'
prior notice of non-renewal.

         Dependence on Dow Jones Telerate, Inc.; Risk of Termination. 
         -----------------------------------------------------------

         Historically, MGI provided its services, with limited exceptions,
exclusively through screens provided by DJM. In late 1993 MGI exercised its
option under its contract with DJM to deliver its services on a non-exclusive
basis through other Vendor Distribution Firms. Following MGI's exercise of its
option under the DJM contract to distribute its services on a non-exclusive
basis, the royalty fee payable to DJM thereunder increased substantially, which
has required MGI to generate substantial incremental volume in order to offset
that increase. See "MGI Management's Discussion and Analysis of Financial
Condition and Results of Operations." MGI believes that its decision to
distribute MGI's services on a non-exclusive basis will continue to enable MGI
to generate such incremental volume, but there can be no assurance in this
regard.

         The agreement with DJM also provides that in the event of a "change of
control" of either party, the other party has the right to terminate the
agreement upon at least 20 days' prior notice. A "change of control" is defined
in the agreement as a change in the possession of the ultimate power to,
directly or indirectly, direct or cause the direction of the management or the
policies of such party, whether through the ownership of voting securities, by
contract or otherwise. MGI does not believe that the Merger will constitute a
change of control of MGI. Termination of MGI's agreement with DJM would have a
material adverse impact on MGI's results of operations and financial condition.

         Significant International Operations; Impact of Foreign Laws and
         ----------------------------------------------------------------
         Currency Fluctuations.
         ---------------------

         MGI provides services to institutional clients in 57 countries and
derived a substantial portion of its revenue in 1996 from the sale of its
services in countries outside the United States. International operations
generally are subject to various risks that are not present in domestic
operations. Various foreign jurisdictions have laws and regulations that
regulate MGI's business, which are in addition to U.S. federal and state
regulation. Also, various foreign jurisdictions have laws limiting the right and
ability of foreign subsidiaries to pay dividends and remit earnings to
affiliated companies unless specified conditions are met. Further, sales in
foreign jurisdictions typically are made in local currencies, and transactions
with foreign affiliates customarily are accounted for in foreign currencies. To
the extent MGI does not take steps to mitigate the effect of changes in the
relative value of the U.S. dollar and these foreign currencies, MGI's results of
operations and financial condition (which are reported in U.S. dollars) could be
affected adversely by negative changes in these relative values. MGI does not
presently intend to take any steps to mitigate such effects of possible changes
in the relative value of the U.S. dollar and these foreign currencies.

         Regulation. 
         ----------

         MGI's business is subject to regulation under various federal and state
laws and regulations, as well as the laws and regulations of certain foreign
jurisdictions where MGI or its subsidiaries have offices and/or where its
services are sold. MCM and its subsidiary, McCarthy, Crisanti & Maffei, S.A.
("MCM S.A."), are both registered commodity trading advisers with the
Commodities Futures Trading Commission. In addition, MCM Asia Pacific Co., Ltd.
("MCM Asia Pacific") has recently been advised by the Monetary Authority of
Singapore that it will be required to register as a futures trading adviser and
investment adviser in Singapore. These laws and regulations are primarily
intended to benefit or protect MGI's clients and generally grant supervisory
agencies and bodies broad administrative powers, including the power to limit or
restrict MGI's ability to carry on its business if it fails to comply with such
laws and regulations. In such event, the possible sanctions that may be imposed
include suspension of individual employees, limitations on engaging in certain
types of business for specified periods of time, revocation of MCM's and MCM
S.A.'s commodity trading adviser and other registrations, censures and fines,
any of which could have a material adverse effect on MGI's business. MGI
believes that it is currently in substantial compliance with all applicable laws
and regulations, other than the requirement to register in Singapore (which MGI
is in the process of satisfying).

                           THE MERGER AND THE EXCHANGE

         The following description summarizes the material terms of the Merger
and the Exchange. This description does not purport to be complete and is
qualified in its entirety by reference to the Merger Agreement, a copy of which
is set forth as Annex A to this Information Statement/Prospectus and is
incorporated herein by reference. All holders of MGI Common Stock are urged to
read Annex A in its entirety.

GENERAL

         This Information Statement/Prospectus serves as a Prospectus of the
Parent with respect to the Units to be issued pursuant to the proposed Merger to
the holders of MGI Common Stock, which Prospectus is part of a Registration
Statement on Form S-4 filed by the Parent with the Commission under the
Securities Act.
         The Merger Agreement provides that on the Closing Date, Sub, a wholly
owned subsidiary of the Parent, shall merge with and into MGI. MGI shall be the
surviving corporation of the Merger and as a result shall become a wholly owned
subsidiary of the Parent. MCM's existence will not be affected by the Merger and
Exchange. Following the Merger, MGI shall continue to be governed by the laws of
the State of Delaware. At the time the Merger becomes effective, each share of
MGI Common Stock (excluding treasury shares and shares held by stockholders who
perfect their dissenters' rights) shall cease to be outstanding and shall be
converted into the right to receive Units, as provided in the Merger Agreement.
         Simultaneously with the Merger, the Parent will acquire all of the
outstanding equity interests in CERA through the Exchange. The cash portion of
the consideration to be paid to the CERA Stockholders and Goldman for such
equity interests will be paid through the CERA Cash Distribution. In order to
take advantage of certain tax benefits arising from CERA's current status as an
S corporation, the portion of the CERA Cash Distribution to be paid to the CERA
Stockholders (in an aggregate amount equal to $21,510,000) will not be paid
directly by the Parent or MGI, but instead will be paid by CERA through the
mechanism of a cash distribution by CERA to its stockholders on the day
immediately preceding the Closing Date. The remainder of the CERA Cash
Distribution will be paid through the purchase by CERA, for a purchase price of
$2,390,000, of a portion of the limited partnership interest in CERA LP held by
Goldman. Pursuant to the Merger Agreement, MGI has agreed to cause MCM to make
the CERA Distribution Loan to CERA in order to provide CERA with the funds to
make the CERA Cash Distribution. MCM intends to make the CERA Distribution Loan
to CERA on the day immediately preceding the Closing Date. The CERA Stockholders
have agreed in the Merger Agreement to cause CERA to apply a portion of the
proceeds from such loan, together with CERA's available cash, to the extent
necessary, to make the CERA Cash Distribution. The Parent expects that the CERA
Distribution Loan will be financed through MCM's available cash and borrowings
by MCM under a senior bank Credit Agreement (the "Credit Agreement") to be
entered into shortly before the CERA Distribution Loan is made. Such borrowings
under the Credit Agreement will be made by MCM rather than by the Parent
because, as a holding company with no substantial operations, the Parent would
be able to meet loan payment obligations only through transfers of funds from
its subsidiaries and, because the Parent will be treated as a partnership for
tax purposes, the holders of Units would be taxed on any dividends paid to the
Parent by its subsidiaries to fund such obligations.
         The Merger Agreement also provides that the CERA Stockholders will
exchange the shares of CERA Common Stock owned by them for Units, the right to
receive the CERA Contingent Units and Contingent Options to purchase Units, and
that Goldman will exchange the remaining limited partnership interest in CERA LP
owned by it after the CERA Cash Distribution for Units, the right to receive the
Goldman Contingent Units and a Contingent Option to purchase Units. As a result,
CERA will become a wholly owned subsidiary of the Parent. Following the
Exchange, CERA shall continue to be governed by the laws of the Commonwealth of
Massachusetts. Immediately upon completion of the Goldman Exchange, the Parent
will transfer or cause to be transferred to CERA the limited partnership
interest in CERA LP acquired from Goldman in the Goldman Exchange. Upon such
transfer, CERA will become the sole partner of CERA LP and CERA LP will be
dissolved by operation of law.

         The Merger Agreement also provides that promptly after the Closing
Date, the Parent will sell to CERA, and CERA will grant to the CERA Employees,
pursuant to the CERA Unit Grant Plan, Units and rights to receive the CERA
Employee Contingent Units. CERA will also grant options to purchase an aggregate
of 231,500 Units to certain employees of and consultants to CERA, pursuant to
the CERA Option Plan. In addition, each Existing MGI Option shall automatically
be converted into an equivalent option to purchase Units. On the Closing Date,
MGI will also grant the Brera Options to Brera, and CERA will grant the Jordan
Options to Jordan.

         If all conditions to the obligations of the parties to consummate the
Merger and the Exchange are either satisfied or waived (as permitted), the
Merger will be consummated. See "--Conditions to Obligations of the Parties." A
copy of the Merger Agreement is set forth as Annex A of this Information
Statement/Prospectus.

BACKGROUND OF THE MERGER AND THE EXCHANGE

         During the summer of 1996, the Board of Directors of CERA directed its
financial advisor, Wm. Sword & Co. ("Sword"), to investigate corporate finance
alternatives, including soliciting acquisition and business combination offers
from several third parties. As a result of these efforts, CERA actively
analyzed, with the assistance of Sword, several acquisition proposals for CERA,
including a proposal for an equity investment in CERA, proposals for an outright
acquisition of CERA and a proposed transaction with MGI. As part of its strategy
to expand its business through identifying and developing opportunities to serve
new markets and launch new services, from time to time MGI has explored
acquisitions of or strategic alliances with a number of companies whose
businesses complemented those of MGI. During the fall of 1996, MGI was informed
by Goldman Sachs that CERA was soliciting acquisition proposals, and MGI became
interested in the opportunities to strengthen and extend both MGI's and CERA's
existing businesses and to improve the ability of the combined companies to
access the financial and equity markets.

         CERA considered the strategic attractiveness of the proposals of each
of these third parties in areas including the structure and terms of the
proposed consideration, the complimentary nature of each third party's business
and the ability of each third party to expand CERA's customer base and
strengthen its product offerings and product distribution methods.

         Discussions between CERA and MGI were initiated by their respective
financial advisors during November and December of 1996 in an effort to explore
the possibility of a strategic transaction between the two parties. On December
2, 1996, representatives of CERA, MGI and Goldman Sachs met at the offices of
CD&R to discuss the two companies, their financial results and the objectives of
their respective owners, and these parties met again on December 10, 1996 at the
offices of CD&R to discuss possible transaction structures and relative
valuation criteria.

         On December 18, 1996, a meeting was held at the offices of CERA in
Cambridge, Massachusetts, at which Messrs. Yergin, Stanislaw, Rosenfield,
Cribiore and McMahon discussed the business of CERA, specific ways in which CERA
could work with MGI and the ways in which a transaction structure might be
developed that met the goals of all of the parties. Throughout the remainder of
December 1996 and January 1997, the parties discussed the potential terms of a
transaction, including the amount and nature of the consideration to be paid to
the CERA Stockholders and Goldman for their interests in CERA and the general
structure of and governance arrangements for the combined companies following
the consummation of the transaction.

         At a meeting on January 30, 1997, Sword reviewed with the CERA Board of
Directors proposals relating to possible business combinations that had been
submitted to Sword, as CERA's financial advisor, from several investors,
including MGI.

         At meetings held at MGI's offices in New York City on February 10 and
February 21, 1997 and at CERA's offices in Cambridge on February 18, 1997,
representatives of MGI and CERA and their respective financial advisors met to
conduct financial and business due diligence and to discuss further the
feasibility of a business combination of MGI and CERA.

         At meetings held at CD&R's offices in New York City on February 25,
1997 and March 6, 1997 and in a number of telephone conferences during this
period, the outline of the basic terms of a combination of MGI and CERA were
negotiated and tentatively agreed upon by representatives of MGI and CERA,
including the aggregate amount of cash consideration to be paid to the CERA
Stockholders and Goldman for their equity interests in CERA (which consideration
will be paid in the form of the CERA Cash Distribution), the percentage of the
equity in the combined companies to be initially allocated to them and the
aggregate amount of the contingent consideration (in the form of the Contingent
Units and the Contingent Options) that would be earned by the CERA Stockholders
and Goldman upon the achievement by CERA of specified revenue growth rates. In
arriving at these terms, the respective parties considered, among other factors,
the historical and projected financial performance of MGI and CERA, including
the growth rates of their respective revenues and earnings, and the amounts that
had been paid (as a multiple of revenues and earnings) for comparable companies.
Over the past several years, MGI's operating performance had been very strong
and stable, and it had benefited from the growth in the securities and financial
markets during this period. CERA's operating performance during this same period
had been more uneven. As a result, MGI believed that MGI was a more valuable
company than CERA. However, MGI also believed that, due in part to the ongoing
deregulation of the energy industry in developed countries, CERA had a greater
potential for growth over the next few years. MGI recognized this potential by
including contingent consideration, based upon the achievement by CERA of
certain revenue growth targets, in the acquisition price for CERA. MGI also
considered the potential impact that a combination with CERA would have on MGI's
projected financial results, taking into account the expected borrowings that
would be incurred in order to finance such combination, and the importance of
requiring that the Founding Stockholders maintain a significant equity interest
in the combined companies and enter into employment agreements with CERA. MGI
expected that the cash portion of the consideration to be paid to the CERA
Stockholders and Goldman for their equity interests in CERA would be financed
through MCM's and CERA's available cash and bank borrowings.

         At a meeting held on March 13, 1997 at the offices of MGI's New York
counsel, Debevoise & Plimpton, business, legal, tax, accounting and financial
representatives of CERA and MGI met to discuss the parameters of a transaction
and structural issues.

         At a meeting of the Board of Directors of MGI held on April 7, 1997,
the Board was advised of the status of the negotiations with CERA, and the
potential benefits of the proposed transaction with CERA were discussed,
including the opportunity to further expand MGI's client base through the
cross-marketing of services and the leveraging of each company's familiarity
with and expertise in specific markets, and the improved access to the financial
and equity markets that might result from a combination of the two companies.
Mr. Yergin, who attended the meeting at the invitation of the Board, also
reviewed for the Board the historical development of CERA's business and its
current business strategies, operations and management structure.

         At a CERA Board of Directors meeting on April 8, 1997, Sword reviewed
with the Board the status of the negotiations with MGI and the Board authorized
management to proceed to negotiate a definitive transaction. Additional meetings
between representatives of MGI and CERA were held on April 11, May 14 and May 29
at the offices of Brera in New York; in each case, specific elements of the
proposed transaction were discussed and refined.

         Meetings with CERA and its legal advisors took place on May 16 at the
offices of Hale and Dorr LLP in Boston and meetings with MGI and its legal
advisors took place on June 20 at the offices of Debevoise & Plimpton in New
York City. Numerous telephone conferences among legal and financial
representatives of each company also took place.

         In early May of 1997, draft documentation was circulated to the parties
by Debevoise & Plimpton, and during May, June and July, the parties negotiated
and finalized the Plan of Merger and Exchange Agreement, Amended and Restated
Limited Liability Company Agreement and related documentation.

         On July 30, 1997, the Boards of Directors of each of CERA and MGI met
in Cambridge and New York City, respectively, to review and approve the merger
agreement. The Merger Agreement was executed by the parties on August 1, 1997.

REASONS FOR THE MERGER AND THE EXCHANGE; FACTORS CONSIDERED BY THE BOARD OF
DIRECTORS OF MGI

         Factors Considered by MGI's Board.

         The Board of Directors of MGI has carefully considered the terms of the
Merger and the Exchange and believes that the Merger and the Exchange are in the
best interests of MGI and its stockholders. The MGI Board has approved the
Merger and the related transactions, and believes that the Merger and the
Exchange will enhance the values of the combined companies.

                                       38
<PAGE>   41
         The material factors that were considered by the Board in reaching its
decision are described below:

         CERA's Business.  The Board considered the nature of CERA's business
and the potential strategic advantages and growth opportunities presented by the
proposed transactions, including the opportunity to further expand MGI's client
base through the cross-marketing of services and the leveraging of each
company's familiarity with and expertise in specific markets, and the improved
access to the financial and equity markets that might result from a combination
of the two companies.

         The Terms of the Exchange.  The Board considered the respective
percentages of the outstanding equity interests in the Parent that would be
held by the MGI stockholders and by the CERA Stockholders, Goldman and the CERA
Employees as a group as a result of the Exchange and the grant of Units to the
CERA Employees. The Board also considered the amount and anticipated value of
the consideration to be paid to the CERA Stockholders and Goldman, including
the amount of cash that the CERA Stockholders and Goldman would receive in the
CERA Cash Distribution and the amount, terms and consequences of the issuance
of the rights to receive the Contingent Units and the Contingent Options,
including the dilution that would result from the issuance of the Contingent
Units and the Units subject to the Contingent Options and the fact that the
issuance of the Contingent Units and the exercisability of the Contingent
Options would be based upon the attainment by CERA of certain compound annual
growth rates in its revenues.

         Financial Analyses of the Transactions.  The Board was presented with
information analyzing the consideration (including the CERA Cash Distribution)
to be paid in the Exchange, as a multiple of CERA's historical and projected
revenues and earnings before interest, taxes, depreciation and amortization, as
adjusted to take into account certain changes in the Founding Stockholders'
salaries and in employee bonuses that were expected to occur following the
consummation of the Transactions ("EBITDA"). The historical multiples of
revenues and EBITDA were then compared to the multiples paid in comparable
merger transactions. Based upon the financial information that had been provided
to MGI by CERA's management, including CERA's preliminary historical financial
results for the fiscal year ended June 30, 1997, the Board was informed that the
value of the consideration to be paid to the CERA Stockholders, Goldman and the
CERA Employees, excluding the Contingent Units, as multiples of CERA's
historical revenues and EBITDA, were generally within the same range as the mean
and median multiples of historical revenue and earnings before interest and
taxes ("EBIT") paid in recent acquisitions of companies in the information and
research services business. Taking into account the Contingent Units, CERA's
historical revenue multiple would be between the mean and median historical
revenue multiples for such comparable acquisitions, and CERA's historical EBITDA
multiple would be somewhat higher than the corresponding mean and median EBIT
multiples for such comparable acquisitions. CERA's EBITDA was considered to be
comparable to the EBITs of these companies due to the immaterial amount of
CERA's historical depreciation and amortization. It was noted that the
individual multiples for each such acquisition varied widely, and that the
amount of the acquisition price paid in any particular transaction tended to be
highly dependent upon the specific circumstances of the transaction.

         The multiples for CERA's projected EBITDA for the fiscal year ending
June 30, 1998 were also compared to the public trading values of four companies
in the information services industry, which were of a similar size to CERA. The
projected EBITDA multiples for these four companies were significantly higher
than CERA's projected EBITDA multiple, while CERA's average projected EBITDA
growth rate for its 1998 and 1999 fiscal years was only somewhat lower than the
average projected EBITDA growth rate for the 1997 and 1998 fiscal years of three
of these four companies. CERA's projected EBITDA multiple was found to be
comparable to the projected EBITDA multiples of a number of more traditional
publishing companies. The Board discussed the fact that, while MGI's historical
earnings growth rate had been higher than CERA's, CERA had a very high
historical revenue growth rate and high future revenue and EBITDA growth
expectations. It was noted that CERA's average projected revenue and EBITDA
growth rates for its 1998 and 1999 fiscal years were significantly higher than
MGI's corresponding growth rates for its 1998 and 1999 fiscal years (and on a
combined basis, the Parent's revenue and EBITDA growth rates would surpass the
rates anticipated for MGI on a stand-alone basis).


                                       39

<PAGE>   42
         Corporate Governance and Management Matters.  The Board considered the
anticipated organizational structure of the combined companies, including the
fact that the Parent was a limited liability company and therefore would not be
a taxable entity. The Board discussed the advantages and disadvantages of the
limited liability company structure. It was noted that the companies would be
operated as independent subsidiaries of the Parent. The Board also considered
certain corporate governance arrangements that would become effective following
the consummation of the Merger and the Exchange. It was noted that because a
significant portion of the consideration that would be paid to the Founding
Stockholders for their equity interests in CERA would be paid in the form of
equity interests, including contingent interests, in the combined companies, the
Founding Stockholders had negotiated a number of corporate governance provisions
that would give them significant decision-making powers. For example, following
the Transactions, two of the Founding Stockholders would sit on each of MGI's
and CERA's board of directors. As a result, given the expected mix of affiliated
and independent directors, it would be necessary to build consensus with respect
to the management of the companies. It was also noted that each of the Founding
Stockholders had agreed to enter into a three-year employment agreement with
CERA.

         Ability to Support Financing.  The Board considered the amount that it
was expected that MGI would need to borrow in order to finance the CERA
Distribution Loan. The Board was informed that MGI's management was confident
that the companies would be more than able to support the increased leverage
that would result from such financing.

         Analysis of Factors.  In view of the variety of factors considered in
connection with its evaluation of the Merger and the Exchange, the MGI Board did
not quantify or otherwise assign relative weights to the specific factors
considered in reaching its determination. The Board also did not discuss whether
any particular factor weighed in favor of or against approving the Transactions.


         Benefits to the Combined Companies.

         The Board of Directors of MGI and the management of CERA believe that
the Merger and the Exchange will better position the combined companies to
compete with larger information providers in the global marketplace served by
both companies, by creating an organization with the critical mass and resources
necessary to sustain rapid growth and through the development of world-wide name
recognition for the combined companies that may further enhance the reputation
of the individual businesses. The transactions may also improve the ability of
the combined companies to access the financial and equity markets as a larger,
more diversified and credit-worthy entity. The Transactions will also present
each company with opportunities to further expand their respective worldwide
client bases through the cross- marketing of services and the leveraging of each
company's familiarity with and expertise in specific markets. In addition,
through the planned introduction of management at the Parent level to focus on
and guide the strategic development of MGI's and CERA's respective businesses,
the companies anticipate that they will be in a better position to manage their
growth and drive expansion and acquisition initiatives.

         Benefits to MGI.

         The Board of Directors of MGI believes the Merger and the Exchange, and
the other transactions contemplated by the Merger Agreement, will position MGI
to serve new markets and develop new products. In particular, MGI believes that
affiliation with CERA will present MGI with opportunities to develop and offer
electronically delivered information services, similar to the electronically
delivered services currently provided by MGI, to existing CERA clients within a
variety of energy industries, such as the electricity industry.


                                      40
<PAGE>   43
         Benefits to CERA.

         Management of CERA believes the Merger and the Exchange, and the other
transactions contemplated by the Merger Agreement, will provide CERA with access
to sophisticated electronic distribution and delivery technology and methods and
will enable CERA to meet the expanding needs of its clients by bringing together
CERA's experience and expertise in the energy business with MCM's knowledge of
economic and financial markets.

         Operation of MGI and CERA Following the Merger and the Exchange.

         Following the Closing, MGI and CERA will each be wholly owned
subsidiaries of the Parent and will continue to be operated as separate though
affiliated businesses. As a result, although certain corporate services or
assets (such as leased premises outside the United States) may be shared
following the Closing Date, it is not expected that significant cost savings
from the integration or elimination of overlapping operations will be realized
from the Merger and the Exchange. Instead, the success of the Transactions will
be dependent largely upon each company's ability to derive benefits from its
affiliation with the other company and from the additional managerial attention
at the Parent level that will be provided following the consummation of the
Transactions. While the future operating results of MGI or CERA could be
adversely affected by any significant diversion of attention by the applicable
company's management to the development or operation of the businesses of the
other company, the Parent intends to engage a chief executive officer at the
Parent level following the Closing Date, who will be responsible for, among
other matters, coordinating activities between the two companies. In addition,
the Parent expects that in order to finance the CERA Distribution Loan, to pay
certain fees and expenses relating to the Transactions and, following the
consummation of the Transactions, to fund MGI's and CERA's working capital needs
and other business requirements, including in respect of any future business
acquisitions, MCM will incur indebtedness under the Credit Agreement. While the
incurrence of such indebtedness will cause MGI to become more leveraged, MGI's
management believes that MGI will have sufficient cash flow to meet its
obligations, including payments under the Credit Agreement. See "The Merger and
the Exchange--The Financing." Although there can be no assurance that the
potential benefits of the Transactions will be either partially or fully
realized, a failure to achieve these benefits would be unlikely to have a
material adverse impact on the financial position or results of operations of
either company.

VALUATION OF CERA

         Houlihan Valuation Advisors ("Houlihan") has delivered a valuation
report, dated July 9, 1997 (the "Houlihan Report"), to MGI, with respect to CERA
LP. The Houlihan Report was commissioned by MGI and its representatives to
determine the aggregate fair market value of the general and limited partnership
interests in CERA LP in order to assist MGI in analyzing the financial impact of
alternate transaction structures for the Merger and the Exchange. In the
Houlihan Report, Houlihan concluded that as of June 26, 1997, based upon the
valuation methodologies described below, the aggregate market value, on an
enterprise basis, of 100% of the general and limited partnership interests in
CERA LP was stated reasonably at $40 million.

         Houlihan regularly provides securities valuation and corporate advisory
services to parties requiring an expert's opinion on pricing, structure,
fairness or solvency in connection with mergers, acquisitions, buyouts,
partnerships, employee stock ownership plans, intangible assets, corporate
finance and other matters. Houlihan was selected by MGI, at the recommendation
of CD&R, based upon Houlihan's national reputation as a valuation firm. Houlihan
had not previously provided valuation services to MGI or its affiliates.

         In the Houlihan Report, Houlihan defined fair market value as the
amount at which interests would change hands between a willing buyer and a
willing seller, each having reasonable knowledge of all relevant facts and
neither being under any compulsion to act. Houlihan based its analysis upon
information provided to it by CERA, Sword and other parties, including CERA's
financial statements for the period of four fiscal years ended June 30, 1996 and
the nine months ended March 31, 1997, its pro forma financial statements for the
quarter ending June 30, 1997 and the fiscal years ending June 30, 1998 and 1999
and other information with respect to CERA's historical and projected
operations, financial condition and operating results. CERA LP's historical and
projected financial information was adjusted to assume that employee bonuses
were 30% of pre-bonus earnings, that no bonuses were paid to the CERA
Stockholders and that CERA LP was taxed at a 40% corporate tax rate. In its
report, Houlihan also assumed that the information provided to it was reasonably
complete and accurate and presented fairly the financial position, prospects and
related facts of CERA LP. Houlihan's conclusions in the Houlihan Report and its
underlying analysis conformed to the appraisal guidelines enumerated in the
Uniform Standards of Professional Appraisal Practice Standard 9 and in Revenue
Ruling 59-60.

         In performing its valuation, Houlihan considered two valuation
methodologies: the market approach, including the guideline company method and
the transaction method, and the income approach. In applying the market
approach, Houlihan compared CERA to seven publicly traded companies that were
deemed to be impacted by similar economic conditions and market factors and
viewed as possible alternative investments by risk-averse investors. Houlihan
analyzed the comparable companies' financial information as of March 31, 1997
and used one month average stock prices, with June 26, 1997 as the last trading
date. The Houlihan Report stated that the transaction method did not yield any
useful value indications. In the Houlihan Report, Houlihan concluded that, using
the guideline company method, the value of the CERA LP partnership interests was
$39.5 million, and that, using the income approach, such value was $40 million.

         The Houlihan Report is available for inspection and copying at the
principal offices of MCM, located at One Chase Manhattan Plaza, New York, New
York, during regular business hours, by any interested stockholder of MGI or his
representative who has been so designated in writing.

         right to receive from 14,444 to 85,389 Goldman Contingent Units, and
         (iii) a Contingent Option to purchase 9,874 Units at a per Unit
         exercise price equal to $34.53.

Immediately after the consummation of the Merger, the CERA Exchange and the
Goldman Exchange, it is currently anticipated that a total of 4,731,835 Units
will be outstanding. The number of Units to be issued in connection with the
Merger and the Exchange and the other transactions contemplated by the Merger
Agreement may be adjusted so that the per Unit value as of the Closing Date will
be equal to ten dollars.

         Terms of the Contingent Units and Contingent Options.

         The Contingent Units shall be issued if, and only if, CERA achieves a
compound annual growth rate of revenue (excluding certain types of revenue) from
its current businesses (the "CERA CAGR") of at least 16% during the three-year
period ending June 30, 2000 or, if (A) an acquisition of 50% or more of the
voting power of the Parent's or CERA's outstanding voting equity interests, a
merger, consolidation or similar combination in which 50% or more of the
Parent's or CERA's outstanding voting equity interests are acquired, or a sale
of all or substantially all of the assets of the Parent or CERA, in each case
other than by or to persons or entities who were owners of the Parent's or
CERA's equity interests, or affiliates of such owners, prior to such transaction
(each, a "Sale of the Parent or CERA"), (B) a distribution to holders of Units
of all of the capital stock of CERA, or (C) an underwritten public offering of
equity securities of the Parent or CERA (each, a "Termination Event") shall have
occurred prior to June 30, 2000, during the period from June 30, 1997 to shortly
before the closing of such Termination Event. In the event that the CERA CAGR
for the applicable period shall be

         (A) less than 16%, then the right to receive Contingent Units shall
terminate and no Contingent Units shall be issued,

         (B) at least 16%, then the holders of rights to receive the CERA
Contingent Units, Goldman and the holders of rights to receive the CERA Employee
Contingent Units shall receive an aggregate of 119,204 Units, 14,444 Units and
10,291 Units, respectively,

         (C) at least 20%, then the holders of rights to receive the CERA
Contingent Units, Goldman and the holders of rights to receive the CERA Employee
Contingent Units shall receive an aggregate of 707,661 Units, 85,389 Units and
60,840 Units, respectively, or

         (D) between 16% and 20%, then the holders of rights to receive CERA
Contingent Units, Goldman and the holders of rights to receive the CERA Employee
Contingent Units shall receive a pro rata portion of the number of Units such
holders would have received had the CERA CAGR been 20%;

provided, that if a Termination Event occurs prior to June 30, 2000 that is (x)
a Sale of the Parent or CERA, in which the aggregate value of the consideration
paid for the equity interests in the Parent or CERA, as the case may be, is at
least $225,000,000 in the case of the Parent, or at least $90,000,000 in the
case of CERA, (y) a distribution to holders of Units of all of the capital stock
of CERA, in which the aggregate value of the capital stock of CERA at the time
of such distribution is at least $90,000,000 (an event described in clause (x)
above or this clause (y), a "Qualifying Sale"), or (z) an underwritten public
offering of equity securities of the Parent or CERA, then the CERA CAGR shall be
deemed to be 20%.

         The CERA CAGR will be based on revenues from the businesses engaged in 
by CERA on the date of the Merger Agreement (but excluding all revenues from the
advisory agreement with Goldman or any other agreement which (i) imposes an
exclusivity obligation on CERA or (ii) provides for compensation of CERA in the
form of contingent transaction fees), determined in accordance with generally
accepted accounting principles. See Annex A.

         If a CERA Employee's employment with CERA is terminated, such CERA
Employee's right to receive CERA Employee Contingent Units shall also terminate
and, under certain circumstances, such CERA Employee may be entitled to receive
a cash payment in lieu of receiving such Units.

         Contingent Options shall become exercisable if, and only if, (i) CERA
achieves a CERA CAGR of at least 20% during the three-year period ending June
30, 2000, and (ii) no Termination Event shall have occurred prior to June 30,
2000. Contingent Options shall remain exercisable for five years after the date
such options became exercisable. If a Termination Event occurs prior to June 30,
2000, Contingent Options shall not be exercisable for any Units and all
Contingent Options shall terminate as of the date of the closing of such
Termination Event. 

                                       44
<PAGE>   47
         The rights to receive Contingent Units and the Contingent Options to be
issued to the CERA Stockholders and the CERA Employees shall be transferable
only (i) by will or the laws of descent or distribution upon the death of a CERA
Stockholder or CERA Employee who is a natural person, (ii) in the case of a CERA
Employee of a CERA Stockholder who is a natural person, to a trust the only
actual beneficiaries under which are such CERA Employee or CERA Stockholder
and/or one or more of such CERA Employee's or CERA Stockholder's brothers and
sisters (whether by whole or half blood), spouse, ancestors and lineal
descendants and (iii) in the case of a CERA Stockholder that is a trust, to the
beneficiaries of such trust). The right to receive Contingent Units and the
Contingent Option to be issued to Goldman shall not be transferable.

         Certain Transactions After the Merger and the Exchange.

         On the Closing Date, MGI will grant the Brera Options to Brera or its
designees, which will entitle Brera or such designees to purchase an aggregate
of 33,444 Units at an exercise price of $23.55 per Unit, and CERA will grant the
Jordan Options to Jordan, which will entitle Jordan to purchase 11,132 Units at
an exercise price of $23.55 per Unit.

         Promptly after the Closing Date, the Parent will sell to CERA, for a
purchase price per Unit equal to the value of a Unit on the Closing Date (as
defined herein) as determined pursuant to the Merger Agreement, and CERA will
grant to the CERA Employees, pursuant to the CERA Unit Grant Plan, (i) an
aggregate of 106,875 Units and (ii) rights to receive an aggregate of from
10,291 to 60,840 CERA Employee Contingent Units. After the grant of such 106,875
Units to the CERA Employees, it is currently anticipated that a total of
4,838,710 Units will be outstanding.

         CERA will also pay to the CERA Employees, within thirty days after the
due date for filing the U.S. federal income tax return of CERA for each taxable
year ending after the Closing Date during which any deduction with respect to
the distribution of Units to such employees pursuant to the CERA Unit Grant Plan
is actually utilized by CERA for U.S. federal income tax purposes, an aggregate
amount equal to the amount of any such deduction so utilized by CERA during such
taxable year multiplied by the highest corporate tax rate applicable for federal
income tax purposes for such taxable year.

         After consummation of the Merger and the Exchange and the issuance of
Units to the CERA Employees, and assuming the exercise of all Contingent Options
and the receipt of all CERA Contingent Units, all Goldman Contingent Units and
all CERA Employee Contingent Units, it is currently anticipated that a total of
5,791,344 Units will be outstanding.

         Promptly after the Closing Date, CERA will also grant options to
purchase an aggregate of 231,500 Units, at an exercise price of $18.31 per Unit,
to certain employees of or consultants to CERA pursuant to the CERA Option
Plan. In addition, each outstanding Existing MGI Option shall automatically be
converted into an equivalent option to purchase 9.55555 Units from MGI at an
exercise price of either $10.47 per Unit or $15.03 per Unit. As a result,
Existing MGI Options to purchase an aggregate of 867,912 Units will be
outstanding after such conversion.

ACCOUNTING TREATMENT

         The Merger will be accounted for at historical cost because the merged
entities were under common control. The Exchange will be accounted for under
the purchase method of accounting.

EFFECTIVE TIME

         If all required consents and approvals are obtained, and the other
conditions to the obligations of the parties to consummate the Merger and the
Exchange are either satisfied or waived (as permitted), the Merger will be
consummated and will become effective on the date and at the time that a
Certificate of Merger, reflecting the Merger, is filed with the Secretary of
State of the State of Delaware, the CERA Exchange will be consummated and will
become effective on the date and at the time that the CERA Stockholders exchange
their shares of CERA Common Stock and the Goldman Exchange will be consummated
and will become effective on the date and at the time that Goldman exchanges its
limited partnership interest in CERA LP. See "--Conditions to Obligations of the
Parties."

PROCEDURE FOR EXCHANGE OF CERTIFICATES

         The Merger Agreement provides that, after the Effective Time, each
holder of an MGI Stock Certificate or MGI Stock Certificates who surrenders such
certificate or certificates, together with a completed and signed MGI Holder
Information Form (a copy of which has been enclosed with this Information
Statement/Prospectus), to the Exchange Agent will be entitled to receive a Unit
Certificate or Unit Certificates represented the Units into which such holder's
shares of MGI Common Stock shall have been converted in the Merger. The Parent
currently intends to appoint MGI as the Exchange Agent. Substantially all of the
MGI Stock Certificates currently are held by the MGI Bailee pursuant to the MGI
Bailment Agreement. Each holder of share of MGI Common Stock who wants to MGI
Bailee to surrender such holder's MGI Stock Certificates to the Exchange Agent
on such holder's behalf must complete, execute and deliver to the MGI Bailee a
Holder Information Form and a Letter of Instruction (a copy of which has been
enclosed with this Information Statement/Prospectus), which will authorize the
MGI Bailee to so surrender the applicable MGI Stock Certificates. Promptly after
the receipt of such documents, the MGI Bailee will deliver the applicable MGI
Stock Certificates and Holder Information Forms to the Exchange Agent.

         If any issuance of Units in exchange for shares of MGI Common Stock is
to be made to a person or entity other than the MGI stockholder in whose name
such shares of MGI Common Stock are registered at the Effective Time, it will be
a condition to such exchange that the applicable MGI Stock Certificate
surrendered to the Exchange Agent be properly endorsed or accompanied by an
appropriate instrument of transfer and that the MGI stockholder requesting such
issuance either pay any transfer or other tax required or establish to the
satisfaction of the Parent that such tax has been paid or is not payable.

         Pursuant to the LLC Agreement, all of the Unit Certificates will be
required to be held by the Unit Bailee under the Unit Bailment Agreement.
Accordingly, the Unit Certificates to be issued in the name of those former
holders of MGI Common Stock whose MGI Stock Certificates, together with
completed and signed Holder Information Forms, shall have been surrendered to
the Exchange Agent shall be delivered to the Unit Bailee in accordance with the
Unit Bailment Agreement. The Unit Bailee will hold such Unit Certificates for
safekeeping in a safe deposit box at a financial institution chosen by the Unit
Bailee, and each such former holder of MGI Common Stock will receive a receipt
from the Unit Bailee for the applicable Unit Certificate and a photocopy of such
Certificate. See "The Limited Liability Company Agreement--The Units--Bailment
Agreement."


                                       46

<PAGE>   49
         After the Effective Time, there will be no further transfers of MGI
Common Stock on the stock transfer books of MGI. If an MGI Stock Certificate is
presented for transfer, it will be cancelled and, subject to the receipt of a
completed and signed MGI Holder Information Form and any other required
documentation, a Unit Certificate representing the appropriate number of Units
will be issued in exchange therefor. After the Effective Time and until
surrendered to the Exchange Agent, MGI Stock Certificates will be deemed for all
purposes, other than the payment of distributions, to evidence ownership of the
number of full Units into which the shares of the MGI Common Stock formerly
represented thereby were converted at the Effective Time. No distributions, if
any, payable to holders of Units will be paid to the holders of MGI Stock
Certificates until such certificates are surrendered. Upon surrender of each
such MGI Stock Certificate, all distributions that, after the Effective Time,
shall have become payable with respect to the applicable Units will be paid to
the holder of the Units issued in exchange for such MGI Stock Certificate,
without interest.

FEDERAL INCOME TAX CONSIDERATIONS

         The following summary sets forth the material United States federal
income tax consequences of the receipt of Units in exchange for MGI Common Stock
pursuant to the Merger (or the receipt of cash by holders of MGI Common Stock
exercising appraisal rights) and the ownership and disposition of such Units by
holders of MGI Common Stock who receive Units pursuant to the Merger (the "MGI
Unitholders"). To the extent that this summary contains statements or
conclusions of law, the summary is supported by, and provides a complete
description of the statements and conclusions of law contained in, the opinion
(the "Tax Opinion") of Debevoise & Plimpton, special counsel to MGI ("Tax
Counsel"), a copy of which has been filed as an exhibit to the Registration
Statement of which this Information Statement/Prospectus is a part. The Tax
Opinion is based in part upon facts described in the Registration Statement,
upon facts that MGI and the Parent have represented to Tax Counsel, and upon
certain factual assumptions set forth in the Tax Opinion. Any alteration of such
facts could adversely affect the Tax Opinion rendered.

  
         Neither MGI nor the Parent has applied, and neither intends to apply,
for a ruling from the Internal Revenue Service (the "IRS") concerning any of the
matters set forth in the following summary. Unlike a ruling from the IRS, an
opinion of counsel has no binding effect on the IRS. The authorities on which
the Tax Opinion and this summary are based are subject to various
interpretations, and there can be no assurance that the IRS will not challenge
the conclusions set forth in the Tax Opinion and this summary or that a court
would sustain such conclusions if challenged by the IRS.

        The Tax Opinion and this summary are based on the United States
Internal Revenue Code of 1986, as amended (the "Code"), existing and proposed
Treasury regulations promulgated thereunder (the "Treasury Regulations") and
administrative and judicial interpretations thereof, all as of the date hereof
and all of which are subject to change, possibly on a retroactive basis.

        Neither the Tax Opinion nor this summary addresses the tax
consequences to any holders of Units other than the MGI Unitholders. The tax
treatment of a particular holder of MGI Common Stock may vary depending on the
holder's particular circumstances. The Tax Opinion and this summary are based on
principles of general applicability, and neither the Tax Opinion nor this
summary purports to address all the tax consequences that may be relevant to a
particular holder or to holders who may be subject to special tax treatment
(such as those who received their MGI Common Stock in connection with the
performance of services, banks and other financial institutions, real estate
investment trusts, regulated investment companies, insurance companies,
tax-exempt organizations, dealers in securities, foreign corporations, foreign
partnerships, other foreign entities and individuals who are not citizens or
residents of the United States). In addition, neither the Tax Opinion nor this
summary includes any description of the tax laws of any state, local or foreign
government that may be applicable to a particular holder of MGI Common Stock.

         HOLDERS OF MGI COMMON STOCK ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE RECEIPT OF UNITS
IN EXCHANGE FOR MGI COMMON STOCK PURSUANT TO THE MERGER (OR THE RECEIPT OF CASH
BY HOLDERS OF MGI COMMON STOCK EXERCISING APPRAISAL RIGHTS) AND THE OWNERSHIP
AND DISPOSITION OF SUCH UNITS, INCLUDING THE TAX CONSEQUENCES UNDER STATE,
LOCAL, FOREIGN AND OTHER UNITED STATES FEDERAL TAX LAWS AND THE POSSIBLE EFFECTS
OF CHANGES IN TAX LAWS.

         Classification Of Parent.

         Under the provisions of the LLC Agreement, the Parent will not elect to
be treated as an association taxable as a corporation for federal income tax
purposes. Accordingly, the Parent will be classified as a partnership for
federal income tax purposes unless it is a "publicly traded partnership". The
LLC Agreement contains certain restrictions on transfers of Units and other
limitations, which attempt to prevent the Parent's being treated as a publicly
traded partnership prior to the IPO Date. See "The Limited Liability Company
Agreement--Resales of Units--Restrictions on Transfer" for a description of the
activities of the Members and the Parent that could result in the Parent's being
treated as a publicly traded partnership. Although it is not expected that the
Parent will be treated as a publicly traded partnership, because determination
of such status will depend in large part upon facts existing in the future,
there can be no assurance that such characterization will not occur, and Tax
Counsel cannot provide an opinion on this issue. If the Parent were treated as a
publicly traded partnership, it would be classified as an association taxable as
a corporation, rather than as a partnership, for federal income tax purposes.

         The Tax Opinion and this summary are based generally on the assumption
that the Parent will not be treated as a publicly traded partnership, and will
thus be classified as a partnership for federal income tax purposes. See
"--Ownership of Units-- If Parent Classified as Association Taxable as
Corporation" for a description of certain federal income tax consequences of the
Parent's being classified as an association taxable as a corporation for federal
income tax purposes.



                                       48
<PAGE>   51
         Receipt Of Units In Exchange For MGI Common Stock.

         Sub was formed for the sole purpose of effectuating the Parent's
acquisition of all of the outstanding MGI Common Stock and has conducted no
activities other than those required for the Merger. Accordingly, by analogy to
the conclusions of law set forth in certain Treasury Regulations and IRS
administrative interpretations in which a corporate parent formed a subsidiary
for the purpose of effectuating the parent's acquisition of the stock of another
corporation, the existence of Sub will be disregarded for federal income tax
purposes, and the Parent will be treated as acquiring all of the outstanding MGI
Common Stock directly from the MGI Unitholders in exchange for Units.

         As a result, the conversion of MGI Common Stock into Units, and the
conversion of common stock of Sub into common stock of MGI as the surviving
corporation, in each case pursuant to the Merger, will be treated as a
contribution of such MGI Common Stock by the MGI Unitholders to the Parent in
exchange for such Units.

         Accordingly, for federal income tax purposes, in general, an MGI
Unitholder will not recognize gain or loss upon the receipt of Units in exchange
for MGI Common Stock pursuant to the Merger (the "Merger Exchange"). If,
however, any MGI Unitholder were to receive a related direct or indirect
transfer of cash or other property from the Parent, the Merger Exchange and such
transfer could be recharacterized as a taxable sale or exchange of the holder's
MGI Common Stock under section 707(a)(2)(B) of the Code. Management of the
Parent does not anticipate that the Parent will make any transfer of cash or
other property to any MGI Unitholder that would be treated as directly or
indirectly related to the Merger Exchange. Because the determination of whether
there has been such a related direct or indirect transfer will depend in large
part upon facts existing in the future, there can be no assurance that such a
transfer will not occur, and Tax Counsel cannot provide an opinion on this
issue.

         If an MGI Unitholder does not recognize any gain or loss for federal
income tax purposes upon the receipt of Units in exchange for MGI Common Stock
pursuant to the Merger Exchange, the initial tax basis of such Units will be
equal to the holder's adjusted tax basis in such MGI Common Stock at the time of
the Merger Exchange. See "--Ownership of Units--Adjusted Tax Basis of Units" for
a discussion of adjustments to the tax basis of Units. If such MGI Common Stock
is a capital asset in the hands of the holder at the time of the Merger
Exchange, the holding period for such Units will include the holder's holding
period for such MGI Common Stock.

         Receipt Of Cash By Holders Exercising Appraisal Rights.

         For federal income tax purposes, any holder of MGI Common Stock who
exercises appraisal rights under the DGCL and receives cash equal to the fair
value of such MGI Common Stock from MGI as the surviving corporation of the
Merger will be treated as having had such MGI Common Stock redeemed by MGI as
the issuer of such stock. If the holder exercises or causes to be exercised
appraisal rights for all of the MGI Common Stock actually and constructively
owned, the holder will be treated as having sold MGI Common Stock in exchange
for the cash received. If the holder exercises or causes to be exercised
appraisal rights for only a part of the MGI Common Stock actually and
constructively owned, the holder will be treated either as having sold MGI
Common Stock in exchange for the cash received or as having received the cash as
a distribution possibly taxable as a dividend, depending on whether or not the
holder meets certain requirements set forth in section 302 of the Code.

         Ownership Of Units.

         Allocation of Parent's Income, Gain, Loss, Deduction and Credit.
Assuming that the Parent is not treated as a publicly traded partnership, and
will thus be classified as a partnership for federal income tax purposes (see
"--Classification of Parent"), the Parent will not be subject to federal income
tax. Instead, each MGI Unitholder will be required to take into account, in
computing the holder's own taxable income, the holder's distributive share of
the Parent's items of income, gain, loss, deduction and credit for each of the
Parent's taxable years that end within or with the taxable year of the holder.
Pursuant to the provisions of the LLC Agreement, the taxable year of the Parent
will end on December 31 of each year. The character of such items of income,
gain, loss, deduction and credit in the hands of each MGI Unitholder will be
determined as if each such item were realized directly from the source from
which realized by the Parent or incurred in the same manner as incurred by the
Parent.


                                       49
<PAGE>   52
         Since the activities of the Parent are expected to be limited to the
holding of the MGI Common Stock and the CERA Common Stock, the only types of
income and loss that the Parent is expected to realize are dividend income from
actual or constructive dividend distributions from MGI or CERA, if any, and gain
or loss, if any, upon the sale or other disposition of the MGI Common Stock or
the CERA Common Stock, which is expected to be treated as capital gain or loss.

         In any given taxable year, an MGI Unitholder's distributive share of
the Parent's income and gains net of the holder's distributive share of the
Parent's losses and deductions could exceed the amount of cash or other
property, if any, distributed to the holder during such taxable year.
Accordingly, an MGI Unitholder could be required to pay federal income tax on
amounts not actually distributed.

         Each MGI Unitholder's distributive share of the Parent's items of
income, gain, loss, deduction and credit for federal income tax purposes will
generally be determined in accordance with the provisions of the LLC Agreement.
The LLC Agreement provides that, except for items with respect to any property
contributed to the capital of the Parent by a holder of Units, such items will
be allocated, to the extent permitted under the Code and the Treasury
Regulations, among the holders of Units in accordance with the respective number
of Units owned (and, in the case of items arising out of certain sales or other
dispositions with respect to which certain holders may be treated as owning
Contingent Units, the number of Contingent Units deemed owned). Under section
706(d) of the Code, if in any taxable year there is a change in any MGI
Unitholder's number of Units owned, the holder's distributive share must take
into account the varying numbers of Units held by each holder of Units during
such taxable year.

         The LLC Agreement provides that, in accordance with section 704(c) of
the Code and the Treasury Regulations, items of income, gain, loss, deduction
and credit with respect to any property contributed to the capital of the Parent
by a holder of Units (which would include the MGI Common Stock received pursuant
to the Merger Exchange) will be allocated, for federal income tax purposes,
among the holders of Units so as to take into account any variation between the
holder's adjusted tax basis in such property at the time of its contribution and
its initial book value as reflected on the books and records of the Parent. (See
also "--Ownership of Units--Distributions by Parent".) The LLC Agreement sets
forth the method for allocating such items among the holders of Units. The LLC
Agreement further provides that the initial book value of the MGI Common Stock
received by the Parent pursuant to the Merger will be equal to the number of
Units received in exchange therefor multiplied by the value per Unit as of the
date of the Merger.

         Management of the Parent believes that the allocations of the Parent's
items of income, gain, loss, deduction and credit provided for under the LLC
Agreement should be respected in all material respects under the Code and the
Treasury Regulations. Because determination of such allocations will depend in
large part upon facts existing in the future, there can be no assurance that
such allocations will be so respected, and Tax Counsel cannot provide an opinion
on this issue.

         The LLC Agreement provides that the Parent will use its reasonable best
efforts to send, no later than 60 days after the end of each taxable year, to
each person who held Units at any time during such taxable year, a schedule
showing such person's distributive share of the Parent's items of income, gain,
loss, deduction and credit and such additional information as may be necessary
for the filing of such person's federal income tax return, including the
Schedule K-1 for such person filed with the IRS with the Parent's federal income
tax return. Under section 6222 of the Code, each MGI Unitholder will be required
to treat each such item in a manner that is consistent with the treatment of
such item on the Parent's return or to file with the holder's own federal income
tax return a statement identifying each inconsistency.

         Under section 704(d) of the Code, an MGI Unitholder's distributive
share of any loss of the Parent will be allowed as a deduction only to the
extent of the adjusted tax basis of the holder's Units at the end of the
Parent's taxable year in which the loss occurred (see "--Ownership of
Units--Adjusted Tax Basis of Units"). Any excess of such loss over such basis
will be carried over and allowed as a deduction when the holder has sufficient
basis to deduct such excess.


                                       50
<PAGE>   53
         Distributions by the Parent.  In general, assuming that the Parent is
not treated as a publicly traded partnership, and will thus be classified as a
partnership for federal income tax purposes (see "--Classification of Parent"),
an MGI Unitholder who receives a distribution from the Parent will not recognize
gain upon the distribution, except to the extent that the sum of any cash
distributed and any decrease in the holder's share of the Parent's liabilities
under section 752 of the Code exceeds the adjusted tax basis of the holder's
Units immediately before the distribution (see "--Ownership of Units--Adjusted
Tax Basis of Units"). Under certain circumstances, the distribution of
"marketable securities" is treated as a distribution of cash under section
731(c) of the Code. An MGI Unitholder who receives a distribution from the
Parent will not recognize loss upon the distribution, except that upon a
distribution in complete redemption of the holder's Units where no property
other than cash, unrealized receivables and inventory (within the meaning of
section 751 of the Code) is distributed to the holder, the holder will recognize
loss to the extent of the excess of the adjusted tax basis of the holder's Units
immediately before the distribution over the sum of any cash distributed, any
decrease in the holder's share of the Parent's liabilities under section 752 of
the Code and the adjusted tax basis of any unrealized receivables and any
inventory distributed. Management of the Parent does not expect the Parent to
have any unrealized receivables or inventory. Any gain or loss recognized will
be treated as gain or loss from the sale or exchange of the holder's Units (see
"--Disposition of Units").

         Certain exceptions to the general rule that an MGI Unitholder will not
recognize gain or loss upon a distribution from the Parent exist. If a holder
were to perform services for the Parent or transfer property to the Parent, and
if the distribution were treated as directly or indirectly related to such
performance of services or such transfer of property, then the amount
distributed could be recharacterized as having been paid as compensation for
such services or in exchange for such property under section 707(a)(2)(A) of the
Code.

         In addition, if a holder contributes any property to the capital of the
Parent (which would include the MGI Common Stock received pursuant to the Merger
Exchange), and the holder's adjusted tax basis in such property at the time of
its contribution is not equal to its initial book value as reflected on the
books and records of the Parent (see "--Ownership of Units--Allocation of
Parent's Income, Gain, Loss, Deduction and Credit"), then (i) under section
704(c)(1)(B) of the Code, the holder may recognize gain or loss if the Parent
distributes the contributed property to one or more other holders of Units
within 7 years of the date of contribution, and (ii) under section 737 of the
Code, the holder may recognize gain (but not loss) if the Parent distributes
other property to the holder within 7 years of the date of contribution.

         Adjusted Tax Basis of Units. Assuming that the Parent is not treated
as a publicly traded partnership, and will thus be classified as a
partnership for federal income tax purposes (see "--Classification of Parent"),
the adjusted tax basis of the Units in the hands of an MGI Unitholder will equal
the initial tax basis of such Units (see "--Receipt of Units in Exchange for MGI
Common Stock"), (i) increased by any additional cash or the adjusted tax basis
of any additional property contributed to the Parent by the holder (including
any increase in the holder's share of the Parent's liabilities under section 752
of the Code) and the sum of the holder's distributive share of the Parent's
income and gains and any income of the Parent that is exempt from tax, and (ii)
decreased by any distributions made to the holder by the Parent (including any
decrease in the holder's share of the Parent's liabilities under section 752 of
the Code, except for any such decrease occurring in connection with the
disposition of Units) and the sum of the holder's distributive share of the
Parent's losses and deductions and any expenditures of the Parent that are
neither deductible nor properly capitalizable. Management of the Parent does not
expect the Parent to have any significant liabilities.

         If the Parent Were Classified as Association Taxable as Corporation. If
the Parent were treated as a publicly traded partnership, the Parent would be
classified as an association taxable as a corporation for federal income tax
purposes (see "--Classification of Parent"), and would be subject to federal
income tax at the rates applicable to corporations. As a result, the Parent's
items of income, gain, loss, deduction and credit would be reflected only on its
own tax return. The MGI Unitholders would not be required to take such items
into account in computing the holders' own taxable income, and neither such
items nor the liabilities of the Parent would affect the tax basis of the Units.
Instead, the holders of Units would be taxable in the same manner as
shareholders of a corporation. In general, an MGI Unitholder receiving a
distribution from the Parent would recognize ordinary dividend income to the
extent of the Parent's current and accumulated earnings and profits.
Distributions in excess of the Parent's current and accumulated earnings and
profits would first be treated as a nontaxable return of capital to the extent
of the adjusted tax basis of the holder's Units and then as gain from the sale
or exchange of the Units. The imposition of tax on the Parent would reduce the
amount of distributions that could be made to the holders of Units.

         Disposition Of Units.

         An MGI Unitholder will recognize gain or loss on the sale or exchange
of Units equal to the difference between the amount realized (which will include
any decrease in the holder's share of the Parent's liabilities under section 752
of the Code, assuming that the Parent is not treated as a publicly traded
partnership, and will thus be classified as a partnership for federal income tax
purposes (see "-- Classification of Parent")) and the adjusted tax basis of the
holder's Units disposed of. See "--Ownership of Units-- Adjusted Tax Basis of
Units; --If the Parent Were Classified as Association Taxable as Corporation".

         If the Units are a capital asset in the hands of the holder at the time
of the sale or exchange, the gain or loss will be treated as capital gain or
loss, except, if the Parent is classified as a partnership for federal income
tax purposes (see "--Classification of Parent"), to the extent attributable to
unrealized receivables or inventory of the Parent, within the meaning of section
751 of the Code. Management of the Parent does not expect the Parent to have any
unrealized receivables or inventory. Such capital gain or loss will be treated
as long-term capital gain or loss if the holding period for such Units is more
than one year. In the case of a holder who is an individual, the rate of tax
applicable to any such gain will be reduced if the holding period for such Units
is more than 18 months.

MANAGEMENT AND OPERATIONS AFTER THE MERGER AND THE EXCHANGE

         After the Merger and the Exchange, MGI and CERA will each be wholly
owned subsidiaries of the Parent and will continue to be operated on a
stand-alone basis. MCM's existence will not be affected by the Merger and
Exchange. MGI shall continue to be governed by the laws of the State of
Delaware. As part of the Merger, MGI's existing Certificate of Incorporation
will be amended in its entirety to read as set forth in Exhibit G to the Merger
Agreement. Following the Merger, MGI shall operate in accordance with the
By-laws of Sub as in effect immediately prior to the Effective Time, except that
certain amendments thereto will be effected in connection with the Merger and
the Exchange. CERA shall continue to be governed by the laws of the Commonwealth
of Massachusetts and shall operate in accordance with its Articles of
Organization and By-laws as in effect on the date of the Merger Agreement until
otherwise amended or repealed after the Effective Time, except that certain
amendments thereto will be effected in connection with the Merger and the
Exchange.

         In connection with the Merger and the Exchange, Messrs. Cribiore,
McMahon, Gogel, Nixon, Yergin and Stanislaw and up to seven additional directors
will be named to the Board of Directors of the Parent at the time of or shortly
after the consummation of the Merger and the Exchange. In addition, Messrs.
Cribiore and Yergin will be appointed Chairman and Vice-Chairman, respectively,
of the Board of Directors of the Parent. The LLC Agreement provides for an
executive committee of the Board of Directors of the Parent which, during the
intervals between meetings of the Board, generally will have the powers and
authority of the Board in the management of the Parent. Upon consummation of the
Merger and the Exchange, such executive committee shall be composed of Messrs.
Cribiore, Yergin, Nixon and such other directors as may be designated by the
Board. The persons named as directors of the Parent will also be required to be
named as the directors of CERA and MGI. See "Management."

INTERESTS OF CERTAIN PERSONS IN THE MERGER AND THE EXCHANGE; CONFLICTS OF 
INTEREST
         MGI.

         Certain directors of MGI have interests in the Merger and the Exchange
that present them with potential conflicts of interest. In connection with the
Merger and the Exchange, Messrs. Cribiore, McMahon, Gogel, and Nixon will
continue to be directors of the Parent and Mr. Nixon also will be named as a
director of the Parent. In addition, Mr. Nixon will continue to be the President
and Chief Executive Officer of MGI. Pursuant to his existing employment
agreement with MGI, in his capacity as such President and Chief Executive
Officer, Mr. Nixon will receive in 1998 a base salary of $275,000 and other
customary benefits.

         CD&R.

         CD&R, the manager of C&D Fund IV, provides managerial and financial
advisory services to MGI, and, after the Merger and the Exchange, will also
provide such services to CERA, pursuant to a Consulting Agreement, dated as of
August 31, 1996 (as amended, the "Consulting Agreement"), among CD&R, MGI, MCM
and, after the Merger and the Exchange, CERA. Under the Consulting Agreement,
CD&R is entitled to receive an annual fee of $150,000, together with
reimbursement of out-of-pocket expenses. CD&R will not be paid any additional
amounts in respect of the Merger and the Exchange. Mr. Gogel is President and a
principal of CD&R and a general partner of the general partner of CD&R Fund IV.

         Brera.

         Pursuant to the Cribiore Services Agreement, in exchange for a fee
equal to the sum of the amount of any management fee paid to CD&R under the
Consulting Agreement (for so long as Mr. Cribiore serves as the Chairman of the
Board of each of MGI and MCM) and certain other amounts, Brera has been
providing the services of Mr. Cribiore to assist CD&R in providing managerial
and financial advisory services pursuant to the Consulting Agreement, among
other matters. Brera has made and may continue to make other employees,
including Mr. McMahon, available to assist Mr. Cribiore in providing such
services. In addition to the assistance provided pursuant to the Cribiore
Services Agreement, Brera has provided financial advisory services to MGI with
respect to the structuring and negotiation of the Merger, the Exchange and
related transactions, including the financing thereof and certain executive
compensation arrangements. The Brera Options will be granted to Brera or its
designees in return for such financial advisory services. Mr. Cribiore is
managing principal of Brera, and Mr. McMahon is a principal of Brera.

         CERA.

         Certain directors of CERA have interests in the Merger and the Exchange
that present them with potential conflicts of interest. Mr. David Leuschen, a
director of CERA until June 1997, is an employee of Goldman. In connection with
the Merger and the Exchange, Messrs. Yergin, Rosenfield and Stanislaw (and
affiliated trusts) will each receive Units, a right to receive CERA Contingent
Units, Contingent Options, and a pro rata portion of the CERA Cash 
Distribution. In addition, Messrs. Yergin, Rosenfield and Stanislaw will enter
into employment agreements with CERA, pursuant to which they will receive a
base salary of $265,000, $255,000 and $255,000 per year, respectively. Further,
Messrs. Yergin and Stanislaw will be named as directors of the Parent after the
Merger and the Exchange. Finally, Jordan, a director of CERA until June 1997,
will receive the Jordan Options.  

         Goldman.

         Goldman Sachs, an affiliate of Goldman, provided financial advisory
services to MGI in respect of the transactions contemplated by the Merger
Agreement, for which Goldman Sachs will receive a fee of $750,000 on the
Closing Date. Additionally, Goldman owns a limited partnership interest in CERA
LP which is the subject of the Goldman Exchange described herein. In the
Goldman Exchange, Goldman will receive Units, the right to receive the Goldman
Contingent Units and Contingent Options. In addition, a portion of the limited
partnership interest in CERA LP owned by Goldman will be purchased by CERA as
part of the CERA Cash Distribution for a purchase price of $2.39 million. CERA

                                       54
<PAGE>   57

and Goldman are also parties to an agreement, which by its terms expired on
October 31, 1997, pursuant to which CERA provided certain advisory services to
Goldman. CERA and Goldman are currently discussing the terms upon which CERA
may provide services to Goldman in the future. Consistent with standard
practices in the investment banking industry, Goldman Sachs implemented ethical
procedures in connection with its advisory services to MGI, including ensuring
that persons assigned to advise MGI did not include persons who were
simultaneously involved in either the management of Goldman's ownership interest
in CERA LP or in the purchase of advisory services from CERA under the contract
referred to above and appropriately segregating information received in
connection with the Transactions.


         Jordan.

         Mr. Jordan, a director of CERA until June 1997, was retained by CERA in
1993 to assist CERA in its review of potential strategic partners. In
connection with his engagement, Mr. Jordan assisted CERA by preparing materials
to be delivered to potential strategic partners, consulted with senior
management of CERA, and advised CERA regarding negotiations with third parties.
Pursuant to a consulting agreement, Mr. Jordan received $35,000 in 1996 for such
services. In addition, CERA agreed to pay Mr. Jordan a fee in respect of the
transactions contemplated by the Merger Agreement. In lieu of such payment, Mr.
Jordan has agreed to accept the Jordan Options. See "Management -- Certain
Relationships and Related Transactions."

         As of the date of the Merger Agreement, MGI's directors, executive
officers, certain entities affiliated with MGI's directors and executive
officers and C&D Fund IV in the aggregate held, directly or indirectly, 306,438
shares of MGI Common Stock or approximately 88% of the shares of MGI Common
Stock outstanding as of such date, and CERA's directors, executive officers,
certain entities affiliated with CERA's directors and executive officers in the
aggregate held, directly or indirectly, 235,850 shares of CERA Common Stock or
approximately 98% of the shares of CERA Common Stock outstanding as of such
date.

written notice to the other after 5:00 p.m., New York City time, on December 22,
1997 if the Closing Date shall not have occurred by such date (unless the
failure of the Closing Date to occur shall be due to, in the case of any
termination by MGI, any material breach of the Merger Agreement by MGI, the
Parent or Sub or, in the case of any termination by the Founding Stockholders,
any material breach of the Merger Agreement by the CERA Stockholders or
Goldman), unless such date is extended by the mutual written consent of MGI and

without limitation through the use of diligent efforts to cure such breaches or
failure) be satisfied on or prior to December 22, 1997; or (d) by any of the
Founding Stockholders, if there has been a breach on the part of MGI, the Parent
or Sub of any of their covenants set forth in the Merger Agreement, or any
failure on the part of MGI, the Parent or Sub to perform their obligations under
the Merger Agreement (provided that the CERA Stockholders and Goldman shall have
performed and complied with, in all material respects, all agreements and
covenants required by the Merger Agreement to have been performed or complied
with by them) prior to such time, such that, in any such case, any of the
conditions to the effectiveness of the Merger and the Exchange set

failure) be satisfied on or prior to December 22, 1997.

liability to any person in respect of the Merger Agreement or of the
transactions contemplated by the Merger Agreement on the part of any party to
the Merger Agreement, or any of its directors, officers, employees, agents,
consultants, representatives, advisers, stockholders, partners or affiliates,
except for any liability resulting from any party's breach of the Merger
Agreement. See "The Merger and the Exchange--Expenses and Fees."

         CERA Cash Distribution.

         MGI agreed to cause MCM to make the CERA Distribution Loan to CERA,
subject to MCM being able to obtain the necessary financing to fund such loan,
on the day immediately preceding the Closing Date, pursuant to a loan agreement
substantially in the form and substance reasonably satisfactory to MGI and CERA,
which shall provide that CERA will be required to make cash payments in respect
of principal or interest thereunder prior to June 30, 2000 only to the extent
such payments are required to be made by the board of directors of the Parent.
Each of the CERA Stockholders agreed to cause CERA to apply the proceeds from
the CERA Distribution Loan, immediately upon the receipt thereof, to pay the
CERA Cash Distribution. Each of the CERA Stockholders released CERA and its
directors and officers from all actions and liabilities arising out of the CERA
Cash Distribution.

         Access and Information.

         From the date of the Merger Agreement to the Closing Date, the
Stockholders will, and will cause CERA and CERA LP to, give to MGI, the Parent
and Sub and MGI's, the Parent's and Sub's accountants, counsel and other
representatives reasonable access during normal business hours to such of CERA
and CERA LP's offices, properties, books, contracts, commitments, reports and
records relating to CERA or CERA LP, and to furnish them or provide them with
access to all such documents, financial data, records and information with
respect to the properties and businesses of CERA or CERA LP, as MGI or the
Parent shall from time to time reasonably request. In addition, from the date of
the Merger Agreement to the Closing Date, the Stockholders will, and will cause
CERA and CERA LP to, permit MGI, the Parent or Sub and MGI's, the Parent's or
Sub's accountants, counsel and other representatives reasonable access to such
personnel of CERA and CERA LP during normal business hours as may be reasonably
requested by MGI, the Parent or Sub in its review of the properties of CERA and
CERA LP, the business affairs of CERA and CERA LP and the above-mentioned
documents and records. MGI has similarly agreed to permit CERA, CERA's
accountants, counsel and other representatives access to MGI's offices and to
such personnel of MGI, and to furnish them or provide them with access to
information with respect to the business of MGI, as may be reasonably requested.

         Financial Information.

         From the date of the Merger Agreement to the Closing Date, the CERA
Stockholders will cause CERA LP to make available to MGI, the Parent and Sub,
promptly after the same become available, copies of such monthly management
reports, if any, for CERA LP as may be furnished to senior management of CERA
LP, together with such monthly financial statements as may be furnished to such
management, and MGI will make available to the Founding Stockholders, promptly
after the same become available, copies of such monthly reports, if any, for MGI
as may be furnished to senior management of MGI, together with such monthly
financial statements as may be furnished to such management.

         No Solicitation.

         From the date of the Merger Agreement to the earlier of the closing of
the transactions contemplated by the Merger Agreement and the termination of the
Merger Agreement, none of the CERA Stockholders or Goldman, any of their

encourage any inquiries or proposals for, or enter into any discussions with
respect to, the sale of CERA, CERA LP, the assets of CERA and/or CERA LP, any
equity interest in CERA or any 

                                       61

partnership interest in CERA LP (any such inquiry or proposal, a "CERA
Acquisition Transaction") or (ii) furnish or cause to be furnished any
non-public information concerning CERA or CERA LP to any person (other than MGI,
the Parent, Goldman and their respective representatives, and the professional
advisors to CERA LP, CERA, the CERA Stockholders and Goldman) in connection with
any such inquiries or proposals. The CERA Stockholders shall promptly notify MGI
of any inquiry or proposal received by the CERA Stockholders or any of their
affiliates with respect to any such CERA Acquisition Transaction and will keep
MGI fully informed of the nature, details and status of any such inquiry or
proposal. Similarly, from the date of the Merger Agreement to the earlier of the
Closing and the termination of the Merger Agreement, neither MGI nor any of its
affiliates or any person acting on its behalf shall (i) solicit, initiate or
encourage any inquiries or proposals for, or enter into any discussions with
respect to, the sale of MGI, MCM, the assets of MGI and/or MCM or, other than
pursuant to the existing MGI stock options, any equity interest in MGI or MCM
(any such inquiry or proposal, an "MGI Acquisition Transaction") or (ii) furnish
or cause to be furnished any non-public information concerning MGI or its
subsidiaries to any person (other than CERA, CERA LP, the CERA Stockholders,
Goldman and their respective representatives, and the professional advisors to
MGI, the Parent and Sub) in connection with any such inquiries or proposals. MGI
shall promptly notify the Founding Stockholders of any inquiry or proposal
received by MGI or any of its affiliates with respect to any such MGI
Acquisition Transaction and will keep the Founding Stockholders fully informed
of the nature, details and status of any such inquiry or proposal.

ADDITIONAL AGREEMENTS

         Pursuant to the Merger Agreement, MGI, the CERA Stockholders, the
Parent and Sub have covenanted and agreed, among other things, to the following:

         Noncompetition.

         Each of the Founding Stockholders agreed that during the period
commencing on the Closing Date and ending on the fourth anniversary of the
Closing Date, he would not, directly or indirectly, (A) as an individual
proprietor, partner, member, principal, officer, employee, agent, consultant or
stockholder, develop, produce, market, sell or render (or assist any other
person in developing, producing, marketing, selling or rendering) products or
services competitive anywhere in the United States or elsewhere in the world
with, or (B) engage in business with, serve as an agent or consultant to, or
become an individual proprietor, partner, member, principal or stockholder
(other than a holder of less than 1% of the outstanding voting shares of any
publicly held company) of or become employed in an executive capacity by, any
person, firm or other entity ("Competitor") a substantial portion of whose
business competes anywhere in the United States or elsewhere in the world with,
a substantial portion of the business of the Parent, CERA, MGI or any of their
respective subsidiaries (collectively, the "MGI/CERA Group") that relates to the
financial information, financial analysis, energy information and analysis or
any other business then engaged in by any member of the MGI/CERA Group;
provided, however, that this agreement not to compete will not be deemed to
prohibit any of the Founding Stockholders from teaching courses at educational
institutions or writing books or articles for public sale or making appearances
on television or preparing or otherwise participating in television programs;
and provided, further, that if the employment of a Founding Stockholder with
CERA is terminated after the Closing Date without cause or for good reason (as
defined in the applicable employment agreement between CERA and such Founding
Stockholder), the noncompetition period shall terminate with respect to such
Founding Stockholder on the earlier of (x) the fourth anniversary of the Closing
Date and (y) the first anniversary of the date of termination of such Founding
Stockholder's employment. For the preceding sentence, a "substantial portion"
(x) in the case of the business of Competitor shall mean a line or lines of
business that account for more than 50% of the consolidated revenues of
Competitor and (y) in the case of the MGI/CERA Group shall mean a line or lines
of business that account for more than 25% of the consolidated revenues of the
MGI/CERA Group, in each case for the fiscal year ended immediately prior to the
date on which the Founding Stockholder first proposes to engage in any of the
activities described in clause (B) of the immediately preceding sentence,
provided, however, that in the case of a Competitor that has had less than three
full years of operations, "substantial portion" shall mean a line or lines of



                                       62
<PAGE>   65
business accounting for more than 50% of the projected consolidated revenues of
such Competitor for the two fiscal years next succeeding the date on which the
Founding Stockholder first proposes to engage in any of the activities described
in clause (B) of the immediately preceding sentence.

         Confidentiality.

         Except as otherwise provided in the Merger Agreement, (x) the CERA
Stockholders, Goldman, CERA and CERA LP, agreed to, and agreed to cause their
representatives to, keep confidential all information which, prior to the date
of the Merger Agreement, was or, from and after the date of the Merger
Agreement, is furnished to any of them by MGI or any of its representatives, or
to which the CERA Stockholders, Goldman, CERA or CERA LP, prior to the date of
the Merger Agreement, were or, from and after the date of the Merger Agreement,
are given access, that in any way relates to the business of MGI and (y) MGI
agreed to, and agreed to cause its representatives to, keep confidential all
information which, prior to the date of the Merger Agreement, was or, from and
after the date of the Merger Agreement, is furnished to MGI, or to which MGI,
prior to the date of the Merger Agreement, was or, from and after the date of
the Merger Agreement, is given access, that in any way relates to the business
of CERA or CERA LP. The parties agreed that the restrictions described in the
preceding sentence do not apply to the disclosure of any information, documents
or materials (i) which are or become generally available to the public other
than as a result of a disclosure by the receiving party or any affiliate or
representative of the receiving party in violation of the restriction, (ii)
received from a third party on a non-confidential basis from a source other than
the providing party or its representatives, which source, to the knowledge of
the receiving party after due inquiry, is not prohibited from disclosing such
information to the receiving party by a legal, contractual or fiduciary
obligation to the providing party, (iii) required by applicable law to be
disclosed by such party, or (iv) necessary to establish such party's rights
under the Merger Agreement or any related agreement, provided that, in the case
of clauses (iii) and (iv), the person intending to make disclosure of
confidential information will promptly notify in writing the party to whom it is
obliged to keep such information confidential and, to the extent practicable,
provide such party a reasonable opportunity to prevent public disclosure of such
information or, if appropriate, waive compliance with the restriction. The
parties agreed that these agreements and undertakings shall (x) continue until
the earliest of (i) five (5) years from the date of the Merger Agreement or (ii)
the closing of the transactions contemplated by the Merger Agreement and (y)
survive the termination of the Merger Agreement.

         Registration Statement.

         Each of the parties agreed, and agreed to cause their respective
subsidiaries, controlled affiliates, directors, officers, employees and
representatives to, assist the Parent in the preparation and filing of this

on or prior to the Closing Date, any event with respect to the CERA
Stockholders, Goldman, CERA, CERA LP, MGI or any of their respective affiliates
should occur which is required to be described in an amendment of or supplement
to this Registration Statement, the party or parties to the Merger Agreement
that are familiar with such event agreed to provide the Parent with a
description of such event that will be sufficient to enable the Parent or its
representatives to prepare such amendment or supplement and to otherwise assist
the Parent in the preparation and filing of such amendment or supplement. The
parties agreed that the Parent would prepare this Registration Statement (or
cause it to be prepared), file it with the Commission promptly after the date of
the Merger Agreement, use its commercially reasonable efforts to cause it to be
declared effective and to remain effective through the Closing Date and, if at
any time on or prior to the Closing Date, any event with respect to the CERA
Stockholders, Goldman, CERA, CERA LP, MGI or any of their respective affiliates
shall occur which is required to be described in an amendment of or supplement
to this Registration Statement, prepare such amendment or supplement (or cause
it to be prepared) and promptly file it with the Commission.

         Public Announcements.

         From the date of the Merger Agreement to the Closing Date, except as
required by applicable law, each of the parties agreed not to, and not to permit
any of their affiliates or representatives to, make any public announcement in
respect of the Merger Agreement or the transactions contemplated thereby without
the prior consent of MGI and the Founding Stockholders.

         Further Actions.

reasonable best efforts to take all actions to make effective the transactions

notifications and obtain all consents that may be required in connection with
the Merger Agreement, and the consummation of the transactions contemplated
thereby.

         Notice of Certain Events.

         From the date of the Merger Agreement to the Closing Date, each of the
CERA Stockholders and Goldman, on the one hand, agreed to promptly notify MGI,
and MGI, the Parent and Sub, on the other, agreed to promptly notify the
Founding Stockholders, of: (i) any fact, condition, event or occurrence known to
any of them that will or reasonably may be expected to result in the failure of
any of the conditions contained in Article IV of the Merger Agreement to be
satisfied; and (ii) any actions, suits, claims, investigations or proceedings
commenced or, to the knowledge of the CERA Stockholders, CERA, CERA LP or
Goldman, on the one hand, or MGI, any of its subsidiaries, the Parent or Sub, on
the other, threatened against, relating to or involving or otherwise affecting
CERA or CERA LP, on the one hand, or MGI and its subsidiaries, on the other, or

affairs would have been conducted if the Merger Agreement had not been entered
into.

EXPENSES AND FEES

         The Merger Agreement provides that each party shall be responsible for

<PAGE>   67

APPRAISAL RIGHTS

         Holders of Units are not entitled to dissenters' appraisal rights under
the Delaware Act in connection with the Merger because the Parent is not a
constituent corporation in the Merger.

         MGI stockholders are entitled to rights of appraisal under Section 262
of the DGCL, a copy of which is attached hereto as Annex C, in connection with
the Merger. If the Merger is consummated, each stockholder who has not voted in
favor of the Merger or consented thereto in writing and who otherwise complies
with such Section 262 will be entitled to such rights. The following discussion
summarizes all material provisions of law relating to appraisal rights. The
discussion does not purport to be a complete statement of laws relating to
appraisal rights and is qualified in its entirety by reference to Section 262 of
the DGCL, a copy of which is attached hereto as Exhibit C. This discussion and
Annex C should be reviewed carefully by any holder of shares of MGI Common Stock
who wishes to exercise statutory appraisal rights or who wishes to preserve the
right to do so, as failure to timely and properly comply with the procedures set
forth therein will result in the loss of appraisal rights. Moreover, because of
the complexity of the procedures for exercising appraisal rights, MGI believes
that holders who consider exercising such rights should seek the advice of
counsel. All references in Section 262 and in this discussion to "holder" or
"stockholder" are to the record holder of the shares of MGI Common Stock as to
which appraisal rights are asserted.

         Under the DGCL, in order to exercise their appraisal rights, MGI
stockholders must satisfy all of the following conditions. A written demand for
appraisal of the applicable holder's shares of MGI Common Stock must be
delivered to MGI on or before the twentieth day after the mailing to the MGI
stockholders of an appraisal right notice. (An appraisal right notice is being
sent to each stockholder with this Information Statement/Prospectus.)

         Stockholders electing to exercise their appraisal rights under the DGCL
must not vote for approval of the Merger or consent thereto in writing pursuant
to Section 228 of the DGCL.

         A stockholder who elects to exercise appraisal rights should deliver
the written demand to MGI. The written demand for appraisal must specify the
stockholder's name and that the stockholder is thereby demanding appraisal of
his shares, and should specify the stockholder's mailing address and the number
of shares of MGI Common Stock owned.

         Only the stockholder of record may make a demand for appraisal. If
stock is owned of record in a fiduciary capacity, such as by a trustee,
guardian, or custodian, such demand must be executed by the fiduciary. If MGI
Common Stock is owned of record by more than one person, as in a joint tenancy
or tenancy in common, such demand must be executed by all joint owners. An
authorized agent, including an agent for two or more joint owners, may execute
the demand for appraisal for a stockholder of record; however, the agent must
identify the record owner and expressly disclose the fact that, in exercising
the demand, such person is acting as agent for the record owner.


                                       65
<PAGE>   68
         Delaware law is unclear as to whether a record holder who also is the
beneficial owner of the shares held (or a record holder acting on behalf of a
beneficial owner) may exercise appraisal rights with respect to less than all of
the shares beneficially owned by such beneficial owner. It is MGI's position
that if a record holder who also is the beneficial owner of the shares held (or
a record holder acting on behalf of a beneficial owner) exercises appraisal
rights, the exercise must be with respect to all of the shares beneficially
owned by such beneficial owner. Where the number of shares is not expressly
stated, the demand will be presumed to cover all shares of MGI Common Stock
outstanding in the name of such record owner. Beneficial owners who are not
record owners and who intend to exercise appraisal rights should instruct the
record owner to comply strictly with the statutory requirements with respect to
the exercise of appraisal rights before the expiration of the applicable
twenty-day period.

         Within 10 days after the Effective Time, MGI must provide notice of the
Effective Time to holders of MGI Common Stock, except that if such notice is
sent more than twenty days following the date the initial appraisal rights
notice was sent, such second notice need only be sent to each stockholder who
provided on a timely basis the written demand required under the DGCL and did
not vote for approval of the Merger or consent thereto in writing. Within 120
days after the Effective Time, either MGI or any stockholder who has provided on
a timely basis the written demand required under the DGCL may file a petition in
the Delaware Court of Chancery demanding a determination of the fair value of
the shares of all dissenting stockholders. In connection therewith, such Court
may require that a stockholder who has demanded an appraisal for such
stockholder's shares submit the certificates representing such shares for
notation thereon, and failure by such stockholder to do so may result in
dismissal of the proceedings. Notwithstanding the foregoing, at any time within
60 days after the Effective Time, any such stockholder will have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the Merger. Within 120 days after the Effective Time, any stockholder who
has complied with the requirements of Section 262 of the DGCL, upon written
request, will be entitled to receive from MGI a statement setting forth the
aggregate number of shares not voted in favor of the Merger and with respect to
which demands for appraisal have been received and the aggregate number of
holders of such shares.

         If a petition for an appraisal is timely filed, after a hearing on such
petition, the Delaware Court of Chancery will determine which stockholders are
entitled to appraisal rights and will appraise the "fair value" of the shares
owned by such stockholders, exclusive of any element of value arising from the
accomplishment or expectation of the Merger, together with a fair rate of
interest, if any, to be paid upon the amount determined to be the fair value.
Any such judicial determination of the fair value of such shares could be based
upon considerations other than or in addition to the consideration received in
the Merger, including asset values and the investment value of the MGI Common
Stock. The per share value so determined could be more than, the same as, or
less than the consideration received per share in the Merger. If a petition is
not filed within 120 days after the Effective Time, the appraisal rights of
dissenting stockholders will terminate.

         Failure to strictly follow the steps required by Section 262 of the
DGCL for perfecting appraisal rights may result in the loss of such rights, in
which event an MGI stockholder will be entitled to receive the consideration to
be provided to MGI stockholders pursuant to the Merger for each share of MGI
Common Stock held by such stockholder.

THE FINANCING

         The Parent expects that in order to finance the CERA Distribution Loan,
to pay certain fees and expenses relating to the Transactions and, following the
consummation of the Transactions, to fund MGI's and CERA's working capital needs
and other business requirements, including in respect of any future business
acquisitions, MCM will enter into the Credit Agreement with The Chase Manhattan
Bank and Bank of America N.T. & S.A. (together, the "Lenders"). MCM has received
a commitment letter from the Lenders with respect to $30 million in aggregate
principal amount of loans, subject to various conditions, and is in the process
of negotiating with the Lenders the definitive terms of the Credit Agreement.
Because such terms have not yet been fully agreed upon, the definitive Credit
Agreement may contain provisions that are more or less restrictive than those
described below.

                                       66
<PAGE>   69
         The Parent anticipates that the Credit Agreement will provide for
borrowings in an aggregate principal amount of up to $30 million, under a $15
million term loan facility (the "Term Loan Facility"), a $10 million delayed
draw term loan facility (the "Delayed Draw Term Loan Facility") and a $5 million
revolving credit facility (the "Revolving Credit Facility" and, together with
the Term Loan Facility and the Delayed Draw Term Loan Facility, the
"Facilities"). MCM will be required to use the proceeds from the loans made
under the Term Loan Facility to fund the CERA Distribution Loan. The Delayed
Draw Term Loan Facility will be available, for a period of 18 months following
the Closing Date, to finance future acquisitions of businesses principally
engaged in providing consulting services or providing information or analytic
services (including the distribution of information through any medium). Up to
$1 million of the Revolving Credit Facility availability may be used for standby
and commercial letters of credit, and a portion of such availability also may be
used for certain short-term "swing line" loans. The proceeds from the initial
borrowings under the Credit Agreement will be loaned to CERA pursuant to a loan
agreement between MCM and CERA (the "CERA Intercompany Note") which will
provide, among other things, that prior to June 30, 2000, CERA will be required
to make cash payments in respect of principal or interest thereunder only to the
extent required by the board of directors of the Parent. CERA will be required
to use such proceeds to make the CERA Cash Distribution.

         The loans under the Facilities will bear interest, at the option of
MCM, at a rate equal to either (i) the rate (the "alternate base rate") that is
the highest of the administrative agent's prime rate, the secondary market rate
for three-month certificates of deposit plus 1.0% and the federal funds rate
plus 0.5%, in each case plus up to 0.50% per annum, or (ii) the rate at which
certain Eurodollar deposits are offered in the interbank Eurodollar market plus
up to 1.50% per annum. Swing line loans will bear interest at the alternate base
rate.

         The loans under the Term Loan Facility will be required to be repaid in
16 quarterly installments, beginning on March 31, 1999 and ending on December
31, 2002. Each loan under the Delayed Draw Term Loan Facility will be required
to be repaid in quarterly installments equal to one-twentieth of such loan,
beginning on the quarterly installment date for the Term Loan Facility which is
closest to the date twelve months after the date such loan is made, and the then
outstanding principal amount of each such loan will mature on the fifth
anniversary of the Closing Date. All of the loans then outstanding under the
Revolving Credit Facility also will become due on the fifth anniversary of the
Closing Date.

         Each of the Parent and MGI will guarantee the obligations of MCM under
the Facilities, and such obligations and guarantees will be secured by pledges
of all of the outstanding capital stock of MGI, MCM and CERA and of 65% of the
outstanding capital stock of MCM's foreign subsidiaries, and by security
interests in substantially all of the personal property of the Parent, MGI and
MCM. In addition, CERA's obligations under the CERA Intercompany Note will be
secured by security interests in substantially all of CERA's personal property,
and the CERA Intercompany Note will be pledged to the Lenders.

         In addition, the Credit Agreement will contain (i) customary closing
conditions, (ii) customary or otherwise appropriate default provisions,
including provisions for default in the event that the Merger and the Exchange
are not consummated on the day following the date the initial loans under the
Credit Agreement are made, or upon certain changes in control, and (iii)
customary or otherwise appropriate affirmative and negative covenants, including
restrictions on the ability of the Parent and its subsidiaries, including MGI
and CERA, to incur indebtedness, incur liens, become liable on guarantees and
other contingent obligations, enter into mergers, consolidations or certain
other similar transactions, sell or transfer assets, make distributions to
holders of Units or certain other restricted payments, make capital
expenditures, make investments, enter into transactions with affiliates, engage
in businesses other than providing consulting services or providing information
or analytic services (including the distribution of information through any
medium), or amend the CERA Intercompany Note. The Credit Agreement also will
contain financial covenants with respect to compliance with certain financial
ratio and net worth and earnings requirements.

REGULATORY MATTERS

         Under the HSR Act, and the rules promulgated thereunder, the Merger and
the Exchange may not be consummated until certain information is provided to the
FTC and to the DOJ, and a thirty-day waiting period is observed. C&D Fund IV,
the ultimate parent entity of MGI, and Daniel H. Yergin, the ultimate parent
entity of CERA, each filed a Notification and Report Form pursuant to the HSR
Act with the DOJ and FTC on August 21, 1997. Early termination of the waiting
period was granted on August 29, 1997. At any time before or after the
consummation of the Merger and the Exchange either agency, as well as the
individual states' attorneys general and private parties, could take action to
enjoin the consummation of the Merger and the Exchange, seeking divestiture of
substantial assets of MGI or CERA, or other substantive relief.

                     THE LIMITED LIABILITY COMPANY AGREEMENT

         The following description summarizes the material terms of the LLC
Agreement of the Parent. This description does not purport to be complete and is
qualified in its entirety by reference to the LLC Agreement, a copy of which is
set forth as Annex B to this Information Statement/Prospectus and is
incorporated herein by reference. All holders of MGI Common Stock are urged to
read Annex B in its entirety.
 
ORGANIZATION AND DURATION

         The Parent was recently organized as a limited liability company under
the Delaware Act. Pursuant to the LLC Agreement, which will become effective as
of the Closing Date, limited liability company interests in the Parent will be
represented by Units. The Parent will have perpetual existence unless sooner
dissolved pursuant to the terms of the LLC Agreement. See "Termination and
Dissolution," below.

PURPOSE

         The purposes of the Parent are, and the Parent shall have the power and
authority, to acquire, hold, vote, sell or otherwise dispose of, to receive,
allocate and distribute distributions on and other proceeds of, and to manage,
investments in accordance with the terms of the LLC Agreement, to engage in all
acts or activities as the Parent deems necessary, advisable, convenient or
incidental to the furtherance and accomplishment of the foregoing, and to engage
in any other lawful act or activity for which limited liability companies may be
formed under the Delaware Act. Immediately after the Closing Date, the Parent's
activities will consist solely of ownership of all of the outstanding capital
stock of CERA and MGI and the exercise of rights and performance of obligations
in connection therewith.

MANAGEMENT

         Board of Directors.

         Generally, the business of the Parent will be managed by or under the
direction of a committee of the Parent (the "Board" or the "Board of
Directors"), each member of which (a "Director") will serve until a successor is
elected as provided in the LLC Agreement or until his earlier death, resignation
or removal. The LLC Agreement provides that the Board will consist of at least
three persons, and further requires all members ("Members") of the Parent, at
all times after the Closing Date and until the settlement date of the first
underwritten public offering of equity securities of the Parent or a successor
entity (the "IPO Date"), to vote their respective Units in such manner as may be
necessary to ensure that (A) the Board at all times consists of (i) two of the
Founding Stockholders nominated by the Founding Stockholders, (ii) the chief
executive officer of MCM ("MCM Nominee"), (iii) the chief executive officer (if
any) of the Parent ("CEO Nominee"), (iv) three nominees of C&D Fund IV who are
employees of CD&R, Brera or other affiliates of C&D Fund IV (the "C&D Fund IV
Nominees"), and (v) up to six additional persons not affiliated with CD&R, C&D
Fund IV, Brera or any of the Founding Stockholders, who are nominated by C&D
Fund IV with the consent of Mr. Yergin, or in the event of Mr. Yergin's death,
legal incapacity or termination of employment for cause or disability, Mr.
Rosenfield or Mr. Stanislaw (the "Consenting CERA Principal"), which consent
will not be unreasonably withheld, and (B) all such persons are elected to serve
as Directors. Until the IPO Date, Directors may not be removed without cause
without the consent of the Member or Members that nominated such Director, and
the Member or Members who nominated or appointed any Director whose position has
become vacant due to such Director's resignation, removal or inability to serve
for any reason will be entitled to appoint a replacement Director to fill such
vacancy. A majority of the Members (by number of Units held) or of the Directors
may remove a Director for cause. For the identity of the initial directors, see
"Management," below.

                                       68
<PAGE>   71
         An election of Directors will be held, and new Directors will be
elected (or existing Directors will be reelected), at each annual meeting of
Members, which will be held on the third Tuesday of October of each year
(starting in 1998) or at such other time as the Board of Directors shall
determine. At each election of Directors, each Member will be entitled to one
vote per Unit held of record (other than non-voting Units), and the presence, in
person or by proxy, of the holders of a majority of the Units entitled to vote
will constitute a quorum. Since, as described above, the LLC Agreement requires
all Members to vote their respective Units, at all times prior to the IPO Date,
for the election to the Board of Directors of persons nominated as described in
the preceding paragraph, election of such nominees at all times prior to the IPO
Date is assured absent amendment of the LLC Agreement.

         Until the earlier of (a) the IPO Date and (b) the issuance of the CERA
Contingent Units, the Goldman Contingent Units and the CERA Employee Contingent
Units (collectively, the "Contingent Units"), any (i) acquisition or disposition
of a business or assets having a value in excess of $15,000,000, (ii) a capital
expenditure involving more than $15,000,000, (iii) issuance of Units (or
securities convertible into or exchangeable for Units, or options, warrants or
other rights to acquire Units or such securities) for aggregate consideration in
excess of $15,000,000, other than the Contingent Units, the Contingent Options,
Existing MGI Options, the options granted under the CERA Option Plan or the MGI
Option Plan, and the Units issuable upon exercise thereof, (iv) entry into new
lines of business, (v) dissolution, (vi) public offering of equity securities of
the Parent or a successor entity, and (vi) with certain exceptions, incurrence
of indebtedness or guarantees in respect thereof in excess of $15,000,000, will
require approval of at least 75% of the Directors then in office. In addition,
until the earlier of (a) the IPO Date and (b) the issuance of the Contingent
Units, the sale of 50% or more of CERA or the spin-off to Members of all of
CERA's capital stock will require the approval of the Consenting CERA Principal.

         The LLC Agreement requires that until the IPO Date, the Board of
Directors of CERA and of MGI shall be composed of the same individuals as the
Board of Directors of the Parent.

         Executive Committee.

         The LLC Agreement provides for the establishment of a committee of the
Board of Directors to be designated as the Executive Committee and to be
composed of the Chairman, the Consenting CERA Principal, the CEO Nominee (if
any), the MCM Nominee and such other Directors as may be designated by the
Board. During the intervals between meetings of the Board, the Executive
Committee will have all the powers and authority of the Board in the management
of the Parent, except that the Executive Committee will not have the authority
to take any action requiring (i) a vote greater than a majority of Directors
present as described above or (ii) the consent or approval of the Consenting
CERA Principal or any one or more of the C&D Fund IV Nominees, or authorizing
any distribution by the Parent to the Members.

         Officers.

         The Board of Directors may select certain individuals to be designated
as officers ("Officers") of the Parent, with such titles as the Board may
determine. The Board may appoint a Chief Executive Officer, a President, a Chief
Financial Officer, a Secretary and a Treasurer, and one or more Vice Presidents,
Assistant Secretaries and Assistant Treasurers, provided that until the IPO
Date, the Chief Executive Officer will be appointed by the C&D Fund IV Nominees
with the consent of the Consenting CERA Principal, whose consent will not be
unreasonably withheld. Each Officer will have certain authority by virtue of
being appointed an Officer and may be further authorized from time to time by
the Board of Directors to take any action that the Board of Directors delegates
to such Officer.


                                       69

THE UNITS

         Rights to Distributions and Allocations.

         The LLC Agreement authorizes the issuance of Units for such
consideration and on such terms and conditions as shall be established by the
Board of Directors in its sole discretion without approval of the Members.
Members (i) will be entitled to receive, to the extent of available cash and
cash equivalent assets of the Parent, cash distributions in amounts intended to
enable Members and certain other persons or entities to discharge their United
States federal, state and local income tax liabilities arising from certain
allocations made with respect to the Units as described below, (ii) other than
with respect to certain distributions relating to specified disposition
transactions (as described below), will be entitled on a pro rata basis to such
distributions, if any, prior to the dissolution and liquidation of the Parent as
may be determined by the Board of Directors of the Parent in its sole
discretion, (iii) will be allocated income, gains, losses, credits and
deductions of the Parent in accordance with the respective Units owned by the
Members, subject to certain variations for income tax purposes called for by
applicable provisions of the Code and regulations promulgated thereunder, and
(iv) will be entitled on a pro rata basis, upon dissolution and liquidation of
the Parent, to all remaining assets after satisfaction of the Parent's
liabilities to creditors.

         With respect to distributions to Members (i) of any capital stock of
MGI or less than all of the capital stock of CERA prior to the earlier of the
issuance of the Contingent Units and June 30, 2000, or (ii) of the net proceeds
of any sale or other disposition (other than in a distribution to Members of
capital stock of MGI or CERA), prior to the earlier of the issuance of the
Contingent Units and June 30, 2000, of capital stock of MGI, more than 50% of
the assets of MGI, or capital stock or assets of CERA in a transaction that does
not constitute a Termination Event, Members will be entitled to receive each
such distribution on a pro rata basis, except that each Member who, at the time
of determination, has a right to receive Contingent Units will be treated,
solely for the purposes of such distribution, as if such Member owned the number
of Contingent Units that would have been issuable to such Member if the closing
of a Termination Event (other than an underwritten public offering) that did not
constitute a Qualifying Sale had occurred at such time of determination.

         Voting and Certain Other Rights.

         Except with respect to non-voting Units (the "Non-Voting Units"), which
will be issuable by the Parent only in limited circumstances and only to those
holders of Units subject to certain legal or regulatory constraints on their
ability to possess voting power with respect to any single entity in excess of
certain thresholds, and except with respect to certain rights and obligations
applicable, pursuant to the LLC Agreement, to certain holders of Units with
respect to (i) nomination, election and/or appointment of members of the Board
of Directors, (ii) rights and obligations relating to transferability of Units
and rights to request registration of Units under the applicable securities
laws, (iii) Contingent Units, and (iv) certain other matters, each Unit will be
identical in all respects to each other Unit. Units other than Non-Voting Units
("Voting Units") will be the only class of equity interests in the Parent
outstanding immediately following the closing of the Merger and the Exchange.

         Holders of record of Voting Units will be entitled to notice of, and to
vote at, meetings of the Members and to act with respect to matters as to which
approval of the Members may be solicited. There will be an annual meeting of the
Members starting in 1998, and special meetings of the Members may be called by
the Board, the Chairman or the Vice Chairman of the Board, the Parent's chief
executive officer, or upon written request of Members holding not less than 20%
of the outstanding Units. Holders of Voting Units will be entitled to one vote
per Voting Unit on matters submitted to a vote or consent of holders of Units.
The LLC Agreement provides that the vote of a majority of Voting Units
represented at a meeting of Members at which a quorum is present will be
sufficient for the transaction of business at such meeting, except that, upon
the recommendation of the Board of Directors that the Members give such
approval, the approval of at least two-thirds of the Members (by number of
Units) then entitled to vote at a meeting of Members will be required for (i)
with certain limited exceptions, any merger, consolidation, conversion or
reorganization of the Parent, (ii) dissolution of the Parent and (iii) the sale
or other disposition of all or substantially all of the assets of the Parent or
the sale or other disposition of all of the capital stock of MGI or CERA owned
by the Parent, other than in a spin-off of all of the capital stock of MGI or
CERA. Pursuant to the LLC Agreement, as described above, prior to the IPO Date,
the Members will be required to vote all of their respective Units for the
election as directors of the nominees described under "--Management--Board of
Directors" above.


                                       70
<PAGE>   73
         Appraisal Rights.

         Pursuant to the terms of the LLC Agreement, holders of Units will not
be entitled to any appraisal or dissenters' rights.

         Bailment Agreement.

         Pursuant to the LLC Agreement, all of the Unit Certificates will be
held by the Parent, as the Unit Bailee under the Unit Bailment Agreement. The
Unit Bailee will hold the Unit Certificates for safekeeping in a safe deposit
box at a financial institution chosen by the Unit Bailee, and each Member will
receive a receipt from the Unit Bailee for the applicable Unit Certificate and a
photocopy of such Certificate. During the time the Unit Bailee has possession of
the Unit Certificates of each Member, each such Member will retain all rights of
ownership of the Units represented by such Unit Certificates, including but not
limited to the right to receive and retain distributions, to vote such Units, to
transfer title to such Units (subject to the terms of the LLC Agreement and any
other applicable agreements) and to execute consents, waivers or releases and
otherwise to act in respect of such Units in all matters acted upon by the
Members. Pursuant to the Unit Bailment Agreement, the Unit Bailee will have no
security or ownership interest in the Unit Certificates and each Member will be
entitled to regain possession of such Member's Unit Certificates at any time
upon five days' prior notice and upon compliance with certain other
requirements.

RESALES OF UNITS

         Restrictions on Transfer.

         The LLC Agreement will provide that, during the period ending on the
earlier of three years after the Closing Date and one year after the IPO Date,
each Member who, together with certain related trusts, if any, owned, as of the
Closing Date, 5% or more of the then outstanding Units (each such Member, a
"Restricted Holder"), each such trust and each of such Restricted Holder's and
such trust's Permitted Transferees (as defined below) may transfer Units only
(i) to an unaffiliated third party (A) in a sale of all of the Units pursuant to
an exercise of the take-along rights described in "--Take-Along Rights" below or
(B) pursuant to a merger, conversion, consolidation or reorganization of the
Parent, other than in a transaction described in the following clause (ii), (ii)
pursuant to certain transactions where the organizational form of the Parent is
changed (for example, from a limited liability company to a corporation) but the
owners and proportional ownership of voting securities or other equity interests
before and after such change generally are unchanged, (iii) in a public offering
of Units pursuant to an effective registration statement under the Securities
Act, (iv) to a Permitted Transferee or (v) to the Parent or any subsidiary of
the Parent.

         In addition, prior to the IPO Date, each Member other than a Member
subject to the transfer restrictions described in the immediately preceding
paragraph, and, after the expiration of the period described in the immediately
preceding paragraph, each Member, may transfer such Member's Units only (i) in
any of the transactions described in clause (i) through (v) of the immediately
preceding paragraph, (ii) to a Member who was a Member as of the Closing Date or
(iii) subject to compliance with the participation rights, rights of first offer
and take-along rights described in "--Participation Rights," "--Rights of First
Offer" and "--Take-Along Rights" below, to Restricted Holders or third parties
who are "accredited investors," for cash in transactions that are exempt from
the registration requirements of the Securities Act pursuant to Section 4(2)
thereof. After the IPO Date, in addition to transfers in any of the transactions
described in the immediately preceding sentence, each such Member will also be
entitled to transfer such Member's Units to any third party, subject to
compliance with such participation rights and with Rule 144 or Rule 145 under
the Securities Act, if applicable.

         A "Permitted Transferee" will be defined in the LLC Agreement to mean
(i) any transferee by bequest or the laws of descent or distribution, (ii) any
trust for employees of the Parent and/or any of the Parent's subsidiaries
established under a qualified employee benefit plan, (iii) in the case of any
Member that is a trust, the trust beneficiaries of such trust, (iv) as to any
Member that is a corporation, company, partnership or other entity, certain
affiliates of such Member and (v) in the case of any Member that is an
individual, any trust the only actual beneficiaries under which are such
individual and/or one or more of his brothers and sisters (whether by whole or
half blood), spouse, ancestors and lineal descendants, provided, in each case,
that the Permitted Transferee agrees in writing to be bound by the terms of the
LLC Agreement and complies with certain additional requirements.

                                       71
<PAGE>   74
         Further, (i) any transferee of Units will, unless such requirements are
waived by the Board of Directors of the Parent, be admitted as a substitute
Member only upon (a) execution by the transferee and the transferor of such
instruments as the Board of Directors or any officer of the Parent deems
reasonably necessary or desirable to effect the substitution, (b) the agreement
in writing by the transferee to be bound by the LLC Agreement, and (c) the
agreement in writing by the transferee to provide the Parent with such
information (including the transferee's employer identification number or social
security number, as applicable, and the amount paid for the Units) as the Parent
may request from time to time, (ii) it is a condition to any transfer of Units
that (x) the Board of Directors of the Parent determine that the proposed
transfer will not cause the Parent to violate applicable law or the terms of any
then outstanding indebtedness of the Parent, guarantees of indebtedness or
related documents, result in the Parent becoming subject to certain securities,
employee benefits, investment company and other specified legal requirements, or
otherwise constitute a Prohibited Transaction (as defined in the LLC Agreement),
and (y) in the case of a transfer to a Permitted Transferee (or in a transaction
described in clause (ii) or (iii) of the first sentence of the second preceding
paragraph), the transferor deliver to the Parent (A) an opinion of counsel
reasonably satisfactory to the Parent relating to certain matters specified in
the LLC Agreement, and (B) a certificate concerning compliance with the
restrictions on transfer set forth in the LLC Agreement and certain related
matters, and certain other documentation, and (iii) each person or entity
obtaining Units, other than the persons and entities admitted as Members
pursuant to the Merger, the Exchange or the transfer of Units and Contingent
Units pursuant to the CERA Unit Grant Plan or exercising options to purchase
Units (provided that each such person or entity who exercised such options
executes a subscription agreement and tenders full payment of the exercise price
of such options), will be admitted as an additional Member at the time such
person or entity (A) executes a counterpart of the LLC Agreement, (B) complies
with the applicable resolution, if any, of the Board of Directors of the Parent
with respect to such admission, and (C) is named as a Member in the Parent's
membership register.

         In addition, the LLC Agreement provides certain further restrictions,
which attempt to prevent the Parent's being treated as a "publicly traded
partnership" for tax purposes prior to the IPO Date. Certain of these
restrictions apply directly to the activities of the Members, and others apply
directly to the activities of the Parent (and, thus, indirectly to the Members).
If any Member or the Parent were to engage in any such activities, the Parent
could, as a result, be treated as a publicly traded partnership for tax
purposes. See "The Merger and the Exchange--Federal Income Tax Considerations"
for a discussion of the tax consequences of the Parent's being treated as a
publicly traded partnership. The restrictions on the activities of the Members
provide that Members shall not, through a securities exchange, an interdealer
quotation system such as NASDAQ, or certain types of secondary market
transactions (other than through certain types of transfers treated as private
transfers under the Treasury Regulations), (i) transfer in any manner any
interest in the capital or profits of the Parent, including but not limited to a
Unit and an option to acquire a Unit, or (ii) transfer in any manner, or enter
into, any financial instrument or contract the value of which is determined by
reference to the Parent, other than such an instrument or contract treated as
debt for federal income tax purposes that is neither convertible into nor
exchangeable for an interest in the capital or profits of the Parent and that
does not provide for a payment of equivalent value (any such interest in capital
or profits of the Parent or financial instrument or contract, an "LLC
Interest"). The restrictions on the activities of the Parent provide that the
Parent shall not (i) allow any LLC interest to be listed or traded on a
securities exchange or interdealer quotation system such as NASDAQ, (ii)
participate in the inclusion of any LLC Interest in certain types of secondary
markets or (iii) recognize any transfer of LLC Interests (other than certain
types of transfers treated as private transfers under the Treasury Regulations),
including but not limited to any person's entering into such a financial
instrument or contract, if such transfer is made through such a securities
market, interdealer quotation system or secondary market. In particular, the LLC
Agreement provides that, under such circumstances, the Parent may not redeem the
transferring Member's LLC Interest or admit the transferee as a Member or
otherwise recognize any rights of the transferee with respect to the Parent.

                                       72
<PAGE>   75
         Securities Laws.

         The issuance of the Units pursuant to the Merger will be registered
under the Securities Act and such Units (other than Units issued to "affiliates"
of MGI or the Parent) will be freely transferable under the Securities Act.
However, there is no public trading market for Units, and it is not expected
that there will be a public trading market for the Units in the foreseeable
future. Units issued to affiliates of MGI as of August 1, 1997 may not be sold
except pursuant to an effective registration statement under the Securities Act
or other applicable exemption from the registration requirements of the
Securities Act, including (in the case of such affiliates who are not also
affiliates of the Parent) Rule 145 under the Securities Act.

         Holdback Agreement.

         Under the LLC Agreement, the Units will be subject to a holdback
provision under which such Units may not be transferred in any public sale or
distribution, including sales pursuant to Rule 144 or Rule 144A under the
Securities Act, during the 20-day period prior to and the one-year period after
the effective date of any registration statement for a public offering filed in
respect of any equity securities of the Parent (other than as part of such
public offering).

         Participation Rights.

         Each Member will be entitled, prior to such time as 30% of the then
outstanding Units have been sold to the public pursuant to an effective
registration statement under the Securities Act or pursuant to Rule 144 under
the Securities Act (the "Establishment of a Public Market"), to participate
proportionately in certain "qualifying sales" of Units by a Restricted Holder,
certain related trusts, if any, and/or any of their Permitted Transferees.
Subject to certain qualifications, "qualifying sales" generally will be any
sales by a Restricted Holder, such trusts and/or such Permitted Transferees to a
third party in transactions not involving a distribution and/or sale to the
public (whether pursuant to a public offering registered under the Securities
Act, Rule 144, broker's transactions or otherwise, but not pursuant to Rule
144A or any successor provision) after such Restricted Holder, trusts and/or
Permitted Transferees have sold an aggregate of 5% of the Units held by such
Restricted Holder, trusts and/or Permitted Transferees.

         Rights of First Offer.

         Under the LLC Agreement, prior to the IPO Date, the Units will be
subject to certain rights of first offer in favor of the Parent (whose right may
be assigned to MGI or CERA) and each Restricted Holder. If a holder of Units
desires, prior to the IPO Date, to offer or to sell Units owned by such holder
in a transaction described in clause (iii) of the first sentence of the second
paragraph of "--Restrictions on Transfer" above, such holder must first make an
offer to sell such Units to the Parent and, if the Parent does not accept such
offer within a twenty-day period, to each Restricted Holder at a price and on
the other terms specified by such holder of Units in a notice to the Parent.
Each Restricted Holder shall have the right during the two successive twenty-day
periods following the expiration of the first twenty-day period to purchase such
Restricted Holder's pro rata portion of the number of such Units that the Parent
(or, with respect to the second such twenty-day period, the other Restricted
Holders) shall not have elected to purchase, which right may be exercised
subject to such Restricted Holder securing financing for such purchase. If the
Parent and the Restricted Holders do not elect to exercise such rights with
respect to all the Units so being offered, the holder may sell such Units to a
third party at no less than 90% of the price and on the other terms initially
offered to the Parent and the Restricted Holders.

         Take-Along Rights.

         Under the LLC Agreement, prior to the IPO Date the Units will be
subject to certain "take-along" rights of the holders of more than 50% of the
outstanding Units (the "Majority Holders"). In the event that the Majority
Holders elect to sell all of their Units to a third party, each other holder of
Units will, if requested to do so by the Majority Holders, have an obligation to
sell such holder's Units to such third party on the same terms and at the same
price as the Majority Holders.

         Registration Rights.

         Under the LLC Agreement and subject to the limitations described
therein, the Parent will agree to grant to (i) the holder or holders (other than
the Founding Stockholders and certain related trusts) of 30% of the Registrable
Securities (as such term is defined in the LLC Agreement and which will
generally include all of the Units to be issued in connection with the
transactions contemplated by the Merger Agreement) with respect to the initial
request and 10% of the Registrable Securities with respect to any subsequent
requests, and (ii) with respect to two requests only after the third anniversary
of the Closing Date, the Founding Stockholders holding a specified percentage of
Units, the right to require the Parent to register for resale (subject to
certain minimum registration requirements), under the Securities Act and
applicable state securities laws, Units that such holders or certain of their
affiliates propose to sell. Since the requests for registration under clause (i)
of the immediately preceding sentence exclude the Founding Stockholders and the
initial request thereunder must be made by the holders of at least 30% of the
Registrable Securities, C&D Fund IV will effectively control the initial
registration of the Units if such registration occurs pursuant to the exercise
of registration rights granted under the LLC Agreement prior to the third
anniversary of the Closing Date. The Parent will be obligated to pay all
expenses incidental to the first two registrations requested pursuant to clause
(i) of the first sentence of this paragraph and each of the two registrations
requested pursuant to clause (ii) of such first sentence, in each case,
excluding underwriting discounts and commissions. Subject to certain limitations
set forth in the LLC Agreement, all holders of Units as of the Closing Date will
be entitled to participate in any such registration for resale, or in any
registration of equity securities of the Parent otherwise undertaken by the
Parent.

         Registration Statement on Form S-8.

         The Parent intends to file a registration statement on Form S-8 under
the Securities Act to register all Units issuable under the CERA Unit Grant
Plan, the CERA Option Plan and the MGI Option Plan or upon exercise of the MGI
Employee Options. This registration statement is expected to be filed promptly
following the effective date of the Registration Statement of which this
Information Statement/Prospectus is a part and will be effective upon filing.
The resale of such Units generally will be subject to the restrictions
applicable to Units described above and to certain additional restrictions
contained in or to be contained in the option, grant and subscription agreements
entered into or to be entered into pursuant to such plans or in connection with
such options.

         Certificate Legend. Each certificate representing Units issued to the
holders of MGI Common Stock will bear a legend indicating that such Units are
subject to the restrictions on transfer contained in the LLC Agreement and any
other applicable agreement. Each holder of Units should read carefully the
provisions regarding restrictions on transfer applicable to the Units as set
forth in the LLC Agreement, a copy of which is attached as Annex B to this
Information Statement/Prospectus.

ISSUANCE OF ADDITIONAL SECURITIES

         The LLC Agreement, subject to the requirements of the Delaware Act and
other applicable law, and subject to certain limitations set forth in the LLC
Agreement, grants the Board of Directors the authority to issue and sell
additional Units and other securities of the Parent, at any time and on such
terms and conditions as the Board may determine, and without the approval of the
holders of Units.

         If the Parent proposes to issue or sell, prior to the Establishment of
a Public Market, any additional Units to a Restricted Holder or any affiliate
thereof (subject to certain exceptions), the Parent will be required to offer to
each holder of Registrable Securities who is an "accredited investor," on the
same terms and conditions as will be applicable to the sale to such Restricted
Holder or such affiliate, the right to purchase the number of additional Units
such that such holder of Registrable Securities would have the opportunity to
hold the same percentage of Units, after giving effect to the sale to such
Restricted Holder or such affiliate, as such holder of Registrable Securities
held immediately prior to such sale.

LIMITED LIABILITY

         Generally, the liability of an owner of an equity interest in a
Delaware limited liability company is limited, under the Delaware Act, to the
amount of capital such owner contributes to the company in respect of such
owner's interest in the company plus such owner's share of any undistributed
profits and assets of the company.

CAPITAL CONTRIBUTIONS

         The securities and assets exchanged for Units pursuant to the Merger,
the CERA Exchange and the Goldman Exchange will constitute capital contributions
to the Parent by the persons or entities receiving such Units in connection
therewith. No holder of Units will be required to make subsequent capital
contributions to the Parent.

AMENDMENT OF LLC AGREEMENT

         The LLC Agreement may not be amended except by a written agreement
signed by the Parent and a majority of the Members (by number of Voting Units),
except that (i) any amendment of any provision of the LLC Agreement requiring
the affirmative vote of more than a majority of the Directors then in office, or
the consent or approval of the Consenting CERA Principal or one or more of the
C&D Fund IV Nominees, will also require the corresponding vote of such
percentage of the Directors or the consent or approval of such other person or
entity, as the case may be, (ii) any amendment of any provision of the LLC
Agreement requiring the affirmative vote of a specified percentage or proportion
of the Members or holders of Units will require the affirmative vote of such
percentage or proportion of such Members or holders, (iii) any amendment or
modification of any provision of the LLC Agreement providing for, or resulting
in, the direct reduction or elimination of any right, preference or benefit
granted to any particular person or entity or group of persons or entities will
require the consent of such person or entity or group of persons or entities,
and (iv) any amendment of any other provision of the LLC Agreement (A) to
satisfy any requirements, conditions, guidelines or opinions contained in any
opinion, directive, order, ruling or regulation of the Commission, the IRS or
any other United States federal or state agency, or in any United States federal
or state statute, compliance with which the Board

                                       75
<PAGE>   78
deems in good faith to be in the best interests of the Parent and (B) to cure
any ambiguity or mistake or correct or supplement any provision of the LLC
Agreement that may be incomplete or inconsistent with any other provision
contained therein, may be signed by the Parent only, without any approval of the
Members being required, if such modification or amendment is authorized by the
Board.

FIDUCIARY AND OTHER DUTIES

         The fiduciary obligations of officers, directors, members and
affiliates of limited liability companies is a developing area of the law. In an
effort to create more certainty regarding the duties of the officers and
directors of the Parent to the Parent and the Members, the LLC Agreement
specifies certain standards of behavior required of such persons, sets forth
procedures that may be used for resolution of conflicts of interest and
describes certain activities that will not be deemed to violate fiduciary or
other duties.

         The LLC Agreement provides that, except as otherwise specifically
provided therein, the duties and obligations of Officers, Directors and Members
to the Parent will be the same as the duties owed by officers, directors and
stockholders, respectively, of a corporation organized under the DGCL to such
corporation. The Parent believes that there is more certainty under the DGCL
regarding duties owed by such persons than under the Delaware Act, primarily
because there are many judicial decisions under the DGCL and comparable
corporate statutes. Other provisions of the LLC Agreement contain language that
limits the liability of Officers, Directors, Members, their respective
affiliates and certain other persons (collectively, "Covered Persons") to the
Parent or the holders of Units. Such provisions are intended to permit Covered
Persons to act in good faith reliance on the provisions of the LLC Agreement;
with certain limitations, to allow certain Covered Persons to engage in outside
businesses and activities (including those competitive with the business of the
Parent) and to take for their respective own accounts investment opportunities
without first presenting such investment opportunities to the Parent; and to
permit the Officers and Directors to perform their duties to the Parent, without
undue uncertainty regarding the standards by which they will be judged or undue
risk of liability. The Parent believes that such provisions are necessary to
provide certainty and fairness with respect to the relationships between Covered
Persons and the Parent, some of which may potentially involve conflicts of
interest. See "The Merger and the Exchange--Interest of Certain Persons in the
Merger and the Exchange; Conflicts of Interest." The LLC Agreement provides,
among other things, that a Covered Person will not be liable for any act or
omission if such person acted in the good faith belief that such action was in,
or was not opposed to, the best interests of the Parent and in a manner believed
to be within the scope of authority conferred on such Covered Person by or
pursuant to the LLC Agreement.

INDEMNIFICATION

         The LLC Agreement provides that the Parent will indemnify any person
who is or was or has agreed to become a Director, Officer, employee or agent of
the Parent, or is or was serving or has agreed to serve at the request of the
Parent as a director, officer, employee or agent of another entity or other
enterprise, against liabilities arising in the course of such person's service,
provided that the indemnitee acted in good faith and in a manner reasonably
believed to be in or not opposed to the best interests of the Parent, provided
that with respect to any criminal proceeding, the indemnitee had no reasonable
cause to believe his conduct was unlawful. Such liabilities include all expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement.
The Members will not be personally liable for such indemnification.

RIGHT TO INFORMATION

         In addition to other rights specifically listed in the LLC Agreement,
and subject to such reasonable standards as may be established by the Parent,
each Member is entitled to all information to which a 


                                       76
<PAGE>   79
member of a Delaware limited liability company is entitled to have access
pursuant to Section 18-305 of the Delaware Act under the circumstances and
subject to the conditions therein stated.

TERMINATION AND DISSOLUTION

         The Parent will have perpetual existence, unless sooner terminated
pursuant to the Agreement. The LLC Agreement provides that the Parent will be
dissolved upon (i) the consent of the Board of Directors and two-thirds of the
Members (by number of Units), or (ii) any event which, under the Delaware Act or
other applicable law, would cause the dissolution of the Parent, provided that,
unless required by law, the Parent will not be wound up as a result of any such
event and the business of the Parent will be continued. Notwithstanding the
foregoing, the death, retirement, resignation, bankruptcy or dissolution of any
Member or the occurrence of any other event that terminates the continued
membership of any Member in the Parent under the Delaware Act will not, in and
of itself, cause the dissolution of the Parent.

LIQUIDATION AND DISTRIBUTION OF PROCEEDS

         Upon dissolution of the Parent, the Board of Directors will direct the
liquidation of the Parent's assets and apply the proceeds of liquidation in the
order of priority set forth in the LLC Agreement. Generally, after discharging
the debts and liabilities of the Parent, any remaining proceeds will be
distributed to the Members in accordance with the respective Units owned by
them.

                       SELECTED HISTORICAL FINANCIAL DATA

         The following tables set forth selected historical financial data of
MGI for the four years ended December 31, 1996 and for the nine month period
ended September 30, 1997 and of CERA for the five fiscal years ended June 30,
1997 and for the three month period ended September 30, 1997. The selected
historical financial data of MGI for the four years ended December 31, 1996 and
of CERA for the five fiscal years ended June 30, 1997 were derived from the
audited Consolidated Financial Statements of MGI and CERA, respectively. The
selected historical financial data of MGI for the nine month period ended
September 30, 1997 and of CERA for the three months ended September 30, 1997
were derived from the unaudited Consolidated Financial Statements of MGI and
CERA, respectively, and include, in the opinion of the respective managements,
all adjustments, consisting only of normal recurring adjustments, necessary to
present fairly the data for such periods. The unaudited results of MGI for the
nine month period ended September 30, 1997 and the unaudited results of CERA for
the three month period ended September 30, 1997 are not necessarily indicative
of the results of MGI to be expected for the full year ended December 31, 1997,
or of CERA for the full year ended June 30, 1998, respectively, or for any
future periods. The following tables should also be read in conjunction with
"MGI Management's Discussion and Analysis of Financial Condition and Results of
Operations," "CERA Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the Consolidated Financial Statements of MGI and
of CERA and accompanying notes thereto included elsewhere in this Information
Statement/Prospectus.

                   NOTES TO SELECTED HISTORICAL FINANCIAL DATA

(a)      Two periods have been presented for 1993 to reflect the acquisition of
         MGI's former parent, The Van Kampen Merritt Companies, Inc. ("the VKM
         Acquisition") on February 17, 1993. As a result of the VKM Acquisition,
         the consolidated financial data for the period after the VKM
         Acquisition is presented on a different cost basis than that for the
         period prior to the VKM Acquisition and therefore is not comparable.

(b)      MGI has agreed to redeem certain common stock at fair market value
         under certain defined conditions.

(c)      During these periods, CERA elected S Corporation status under the
         Internal Revenue Code whereby it did not incur any federal and most
         state taxes at the corporate level, as they were borne by CERA's
         stockholders.

                   PRO FORMA CONDENSED COMBINED FINANCIAL DATA
                                   (UNAUDITED)

         The following unaudited Pro Forma Condensed Combined Financial Data are
based on the Consolidated Financial Statements of MGI and CERA included
elsewhere in this Information Statement/Prospectus, as adjusted to give effect
to the Merger and the Exchange and related transactions.

         The unaudited Pro Forma Condensed Combined Statements of Operations of
the Parent are derived from the Consolidated Statements of Income of CERA for
the fiscal year ended June 30, 1996, the fiscal year ended June 30, 1997, and
for the three months ended September 30, 1997, included elsewhere in this
Information Statement/Prospectus, and the Consolidated Statement of Income of
MGI for the year ended December 31, 1996 and the nine months ended September 30,
1997, included elsewhere in this Information Statement/Prospectus, and assumes
that the Merger and the Exchange were consummated as of January 1, 1996. The
unaudited Pro Forma Condensed Combined Balance Sheet of the Parent is derived
from the Consolidated Balance Sheets of CERA and of MGI as of September 30,
1997, included elsewhere in this Information Statement/Prospectus, and the
Balance Sheet of the Parent, included elsewhere in this Information
Statement/Prospectus. The unaudited Pro Forma Condensed Combined Financial Data
should be read in conjunction with the Consolidated Financial Statements of the
Parent, of MGI and of CERA, included elsewhere in this Information
Statement/Prospectus.

         The unaudited Pro Forma Condensed Combined Financial Data of the Parent
do not purport to be indicative of the results that would actually have been
obtained if the Merger and the Exchange had occurred on the dates indicated or
of the results that may be obtained in the future. The unaudited Pro Forma
Condensed Combined Financial Data are presented for comparative purposes only.
The pro forma adjustments, as described in the accompanying data and notes, are
based on available information and certain assumptions that management believes
are reasonable.

         The unaudited pro forma information is based on the historical
Consolidated Financial Statements of the Parent, of MGI and of CERA. The Merger
has been accounted for at historical cost as the merged entities were under
common control. For pro forma presentation purposes it has been assumed that all
shares of MGI Common Stock will be exchanged for Units. The Exchange has been
accounted for under the purchase method of accounting. The purchase price,
including related fees and expenses, has been allocated to the tangible and
identifiable intangible assets and liabilities of CERA with the remainder
allocated to goodwill. The allocation of the purchase price is subject to
revision when additional information concerning asset and liability valuation
becomes available. The pro forma adjustments include adjustments to reflect the
CERA Distribution Loan, the assumed incurrence of $23.9 million of indebtedness
under the Credit Agreement to finance such loan and the CERA Cash Distribution,
changes in amortization of intangible assets relating to the allocation of the
purchase price, the elimination of non-recurring charges for various fees and
costs associated with the Exchange, the change in CERA's tax status, and the
related tax effects of the various pro forma adjustments.

          NOTES TO PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS
                             (Dollars In Thousands)

         The Pro Forma Condensed Combined Statements of Operations (unaudited)
for the year ended December 31, 1996 and the nine months ended September 30,
1997 assume that the Merger and the Exchange and related transactions occurred
on January 1, 1996.

(a)      The Parent was formed on June 30, 1997.

(b)      The Condensed Combined Statement of Operations, for the year ended
         December 31, 1996 of CERA was derived from combining the results of
         operations for the six months ended June 30, 1996 as derived from the
         Consolidated Statement of Income of CERA for the year ended June 30,
         1996, included elsewhere in this Information Statement/Prospectus, with
         the six months ended December 31, 1996, as derived from the
         Consolidated Statement of Income of CERA for the year ended June 30,
         1997, included elsewhere in this Information Statement/Prospectus. The
         Condensed Combined Statement of Operations of CERA for the nine month
         period ended September 30, 1997 was derived from combining the results
         of operations for the six months ended June 30, 1997, as derived from
         the Consolidated Statement of Income of CERA for the year ended June
         30, 1997, included elsewhere in this Information Statement/Prospectus,
         with the three months ended September 30, 1997, included elsewhere in
         this Information Statement/Prospectus.

(c)      The adjustment reflects an increase in interest expense resulting from
         the incurrence of indebtedness under the Credit Agreement, to finance
         the CERA Distribution Loan, in an assumed aggregate principal amount of
         $23,900, assuming an interest rate of 8.5%.

(d)      The adjustment reflects an increase in amortization expense resulting
         from the increase in CERA's intangible assets, including capitalized
         transaction costs, amortized over their useful lives ranging from 5 to
         25 years.

(e)      The adjustment reflects an increase in income tax expense resulting
         from the assumed change in tax status of CERA as a result of the CERA
         Exchange and a net decrease in the provision for income taxes as a
         result of the pro forma adjustments, all assuming an effective tax rate
         of 42%.

(f)      The adjustment reflects the elimination of professional fees of $675
         incurred by CERA during the nine months ended September 30, 1997 that
         were associated with the Exchange.

               NOTES TO PRO FORMA CONDENSED COMBINED BALANCE SHEET
                             (Dollars In Thousands)

         The Pro Forma Condensed Combined Balance Sheet (unaudited) assumes that
the Merger and the Exchange and related transactions occurred on September 30,
1997.

(a)      The Parent was formed on June 30, 1997 with subscribed capital of one
         hundred dollars.

(b)      The acquisition of CERA by the Parent will be accounted for as a
         purchase in accordance with Accounting Principles Board Opinion No. 16,
         "Business Combinations." The purchase price is being allocated first to
         the tangible and identifiable intangible assets and liabilities of CERA
         based upon preliminary estimates of their fair market values, with the
         remainder allocated to goodwill. The total purchase price is as
         follows:

(c)      This adjustment reflects unpaid transaction expenses as of September
         30, 1997 of $2,012.

(d)      The $40,000 cost to acquire 100% of the outstanding CERA Common Stock
         includes cash of $23,900 (incurrence of indebtedness under the Credit
         Agreement to finance the CERA Distribution Loan) and an exchange of
         CERA stock for Units. The value of $40,000 was determined based upon an
         independent third party appraisal. The indebtedness under the Credit
         Agreement will be incurred by MCM, a wholly owned subsidiary of MGI.
         The loan proceeds in turn will be loaned by MCM to CERA, which will use
         such funds to acquire a portion of the limited partnership interest in
         CERA LP, held by Goldman, for $2,390, and to make a distribution of
         $21,510 to the CERA Stockholders. All of the outstanding CERA Common
         Stock (and Goldman's remaining interest in CERA LP), then will be
         exchanged for Units.

(e)      The adjustment reflects the deferred tax asset arising from the change
         in CERA's tax status, resulting from the Exchange.

(f)      Eliminates historical equity.

(g)      This adjustment reflects amounts incurred by CERA in relation to the
         issuance of new equity.

                    MGI MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


GENERAL

         The following is a discussion and analysis of the historical results of
operations and financial condition of MGI and factors affecting MGI's financial
resources. This discussion should be read in conjunction with MGI's Consolidated
Financial Statements, including the notes thereto, appearing elsewhere in this
Information Statement/Prospectus. As used in this MGI Management's Discussion
and Analysis of Financial Condition and Results of Operations, "MGI" refers to
(i) MGI and its subsidiaries for periods from and after the August 1996 spin-off
of MGI by VK/AC Holding, Inc. ("VK/AC") to the holders of its common stock (the
"Spin-Off"), (ii) MCM and its subsidiaries for periods prior to the Spin-Off or
(iii) if the context requires, MCM.

         MCM and its subsidiaries, MCM S.A., MCM Asia Pacific and McCarthy,
Crisanti & Maffei (Europe) Limited ("MCM Europe"), provide specialized on-line
financial information and analysis relating to developments in the U.S. and
international corporate securities, fixed income and currency markets. MGI
distributes its services primarily through on-line telecommunications
information networks to subscribers in 57 countries. Subscribers to MGI's
electronic information services consist almost exclusively of institutional
clients (e.g., major banks, brokers, dealers, government bond and financial
futures trading operations, foreign exchange trading operations, and treasury
departments of major corporations). In addition to MGI's headquarters in New
York, MGI maintains offices in Boston, London, Paris, Tokyo, Hong Kong and
Singapore.

         For the year ended December 31, 1996, nearly half of MGI's total
revenues were attributable to customers located in the United States.
European-based customers accounted for approximately one third of total revenue
and customers based in Asia accounted for the balance. The CorporateWatch(R)
service is responsible for a substantial portion of MGI's revenue earned in the
United States, while the CurrencyWatch(R) service is responsible for a
substantial portion of the revenue earned in the European and Asian markets.

         Revenue from MGI's services has grown substantially since 1992,
principally as a result of investments made by MGI to expand its distribution
and marketing capabilities and enhance its service offerings throughout the
global financial markets. See "Business of MGI--Overview" below. The substantial
increases in revenues have been offset to some extent by (i) increases in vendor
royalties resulting from MGI's decision in late 1993 to distribute its services
on a non-exclusive basis over various Vendor Distribution Firms and (ii)
increases in compensation and benefits resulting from MGI's hiring of personnel
to expand the services offered by its product lines.

         Vendor royalties currently represent MGI's largest item of expense.
Vendor royalties are commissions paid to Vendor Distribution Firms, mainly DJM.
Historically, MGI provided its services, with limited exceptions, exclusively
through screens provided by DJM. In late 1993 MGI exercised its option under its
contract with DJM to deliver its services on a non-exclusive basis through other
Vendor Distribution Firms. As a result of the discontinuation of the exclusive
distribution agreement with DJM, DJM's royalty increased to a level
substantially greater than that in effect while distribution of MGI's services
was made exclusively through DJM. MGI renegotiated the agreement with DJM and
reached agreement in November 1996 with DJM on a reduction in the royalty fee in
respect of subscription revenues above a specified base amount. Since moving to
a multi-vendor distribution system, MGI has increased its sales volume and
believes that this strategy will continue to increase revenues to more than


                                       86
<PAGE>   89
offset the additional vendor royalty costs. However, there can be no assurance
that MGI's strategy will continue to be successful.

         Compensation and benefits costs also have increased as MGI has invested
in additional professional staff to enhance certain product lines, particularly
CurrencyWatch(R) and YieldWatch(R), MGI's two fastest growing services in terms
of revenues. While revenues for these two services have grown substantially, the
additional investment in personnel has kept profit margins on these services
relatively low. MGI believes that as CurrencyWatch(R) and YieldWatch(R) revenues
continue to grow, profit margins will significantly improve, although there can
be no assurance in this regard.

         Historically, MGI has not had any material interest expense. MGI
expects to incur interest expense following the Merger and the Exchange in
connection with the financing of the CERA Distribution Loan.

RESULTS OF OPERATIONS

         Nine Months Ended September 30, 1997 versus 1996

Revenues

         Revenue from research services grew from $26.7 million during the first
nine months of 1996 to $29.8 million during the same period of 1997, an increase
of 11.6%. Revenues for all of MGI's major product lines continue to grow, due
primarily to the expansion of MGI's international customer base and the delivery
of research services through multiple Vendor Distribution Firms to MGI's
customers.

Expenses

         Total expenses in the first nine months of 1997 were $24.2 million, or
$1.7 million more than the same period in 1996, an increase of 7.6%. Sales,
distribution and administrative expense for the first nine months of 1997 was
$23.6 million, an increase of 7.6% over the same period in 1996. This increase
resulted from substantially higher compensation and benefits costs, reflecting
the hiring of additional analysts and research assistants to enhance MGI's
product lines, as well as from increases in occupancy expense and in expenses
associated with the hiring of additional personnel and investments in computer
system enhancements.

         These increased costs were partially offset by overall lower vendor
royalties, reflecting the continuing success of MGI in increasing revenues
through multiple Vendor Distribution Firms.

Net Income

         Net income for the nine months ended September 30, 1997 was $3.2
million, an increase of $0.9 million or 40.1% over the same period in 1996. Net
income grew as a result of increased revenue realized on all of MGI's major
product lines and lower expenses for vendor royalties.

Recent Accounting Pronouncements

         In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income" ("SFAS 130"). SFAS 130 establishes standards for reporting and display
of comprehensive income and its components in a full set of general-purpose
financial statements. SFAS No. 130 is effective for fiscal years beginning after
December 15, 1997. Reclassification of financial statements for earlier periods
provided for comparative purposes is required. The adoption of SFAS No. 130 will
have no impact on MGI's consolidated results of operations, financial position
or cash flows.

         In June 1997, the FASB issued SFAS No. 131, "Disclosure about Segments
of an Enterprise and Related Information" ("SFAS 131"). SFAS No. 131 establishes
standards for the way that public business enterprises report information about
operating segments in annual financial statements and requires that those
enterprises report selected information about operating segments in interim
financial reports issued to shareholders. It also establishes standards for
related disclosures about products and services, geographic areas, and major
customers. SFAS No. 131 is effective for financial statements for fiscal years
beginning after December 15, 1997. The adoption of SFAS No. 131 will have no
impact on MGI's consolidated results of operations, financial position or cash
flows.

         Year Ended December 31, 1996 versus 1995

Revenues

         Revenue from research services grew from $31.1 million in 1995 to $35.8
million in 1996, an increase of 15.1%. Revenues for all of MGI's major product
lines continued to grow, due primarily to the expansion of MGI's international
customer base and the delivery of research services through multiple Vendor
Distribution Firms to MGI's customers.

Expenses

         Total expenses in 1996 were $30.4 million, or $1.3 million more than in
1995, an increase of 4.5%. Sales, distribution and administrative expenses
totaled $29.6 million, an increase of 4.6% over 1995. This increase resulted
from substantially higher compensation and benefits costs, reflecting the hiring
of additional analysts and research assistants to enhance MGI's product lines,
as well as from increases in occupancy expense and in expenses associated with
the hiring of additional personnel and investments in computer system
enhancements.

         These increased costs were partially offset by lower vendor royalties,
reflecting the continuing success of MGI in increasing revenues through multiple
Vendor Distribution Firms.

Net Income

         Net income for 1996 was $3.0 million, an increase of $1.4 or 87.5% over
1995. Net income grew as a result of increased revenue realized on all of MGI's
major product lines and lower expenses for vendor royalties.

         Year Ended December 31, 1995 versus 1994

Revenues

         Research services revenue grew from $26.0 million in 1994 to $31.1
million in 1995, an increase of 19.6%, which was attributable to growth in all
of MGI's major product lines.

Expenses

         Total expenses in 1995 were $29.1 million, or $3.9 million more than in
1994, an increase of 15.5%. Sales, distribution and administrative expense
totaled $28.3 million, an increase of 16.0% over 1994 due to an increase in
compensation and benefits, which in turn reflected additions in personnel as
part of MGI's investment in the CurrencyWatch(R) and YieldWatch(R) product
lines, an increase in occupancy expense associated with MGI's relocation to a
new headquarters in 1994 and an increase in professional fees incurred resulting
from higher outside consulting and computer programming costs in 1995 associated
with MGI's expansion of its computer technology capabilities.


                                       88
<PAGE>   91
         In addition, vendor royalties increased slightly in 1995 over 1994, but
declined as a percentage of total sales, reflecting MGI's ongoing efforts to
distribute its services through multiple Vendor Distribution Firms.

Net Income

          Net income for 1995 was $1.6 million, an increase of $0.9 million or
128.6% over 1994. Net income growth was primarily due to higher revenues for
each of MCM's major services and decreased distribution costs as a percentage of
revenue.

LIQUIDITY AND CAPITAL RESOURCES

         MGI generated cash from operations in the amounts of $5.5 million, $8.4
million and $0.7 million for the nine months ended September 30, 1997 and the
years ended December 31, 1996 and 1995, respectively. Prior to the Spin-Off, Van
Kampen American Capital, Inc., a former affiliate of MGI ("VKAC, Inc."),
provided treasury functions for MGI. All cash was transferred to VK/AC and
applied to pay MGI's costs of operations. MGI did not have any material,
independent sources of credit and did not receive interest credit in respect of
excess cash balances nor was it charged interest for negative cash balances. MGI
continues to receive treasury services (including cash management) from VK/AC
and its affiliates under a services agreement but MGI maintains its own bank
accounts. MGI's principal operating expense is for compensation and benefits,
which it funds with cash from operations. MGI may make significant technology
related capital expenditures in the near future, but MGI believes that its cash
from operations will be sufficient to meet its operating costs and, following
the Merger and the Exchange, any increased debt service costs.

INCOME TAXES

         MCM was a member of the VK/AC group for purposes of filing federal and
certain state and local consolidated, combined or unitary income tax returns
before the Spin-Off. MGI was included in the VK/AC group's 1996 federal and
certain state and local consolidated, combined or unitary income tax returns for
the period beginning August 22, 1996 and ending on the date of the Spin-Off. As
a result of the Spin-Off, MGI and MCM can no longer be included as members of
the VK/AC group for purposes of filing federal, state or local consolidated,
combined or unitary income tax returns. Instead, MCM will be included in federal
and certain state and local consolidated, combined or unitary income tax returns
to be filed by MGI for the period beginning after the Spin-Off. For taxes other
than consolidated, combined or unitary taxes, MCM has historically filed returns
with respect to such taxes on a stand-alone basis and has continued to file such
returns on a stand-alone basis after the Spin-Off.

                    CERA MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


GENERAL

         The explanations and comments on the following pages relate to CERA's
financial performance in different fiscal periods. They should be read in
conjunction with CERA's Consolidated Financial Statements, and the notes
thereto, included elsewhere in this Information Statement/Prospectus.

         CERA's core business is research, analysis and strategic information on
energy industry developments and trends, which is sold, primarily, on a
continuous, renewable retainer basis. CERA offers a number of different retainer
advisory services (see "Business of CERA," below) which are sold, principally,
as annual, renewable contracts. These contracts can vary in price depending on
the level of service and/or the number of advisory services purchased. The
majority of CERA's retainer clients purchase more than one service. The contract
price is billed at the inception of the contract and revenue is recognized
ratably over the contract term. Upon expiration of the contract, revenue does
not continue to be recognized unless and until the contract has been renewed and
billed. In the fiscal years ended June 30, 1997, 1996 and 1995, revenue from
retainer advisory services has increased over the prior fiscal year by 26%, 25%
and 32%, respectively. Revenue from retainer advisory services represented 53%,
of total revenue in the fiscal year ended June 30, 1997, up from 50% of total
revenue in each of the prior two fiscal years.

         The balance of CERA's revenue is derived from custom projects, and
several different activities collectively called "retainer related."

         Custom projects (also described as retainer applications and
consulting) are, generally, client-specific applications of research, data and
knowledge derived from the retainer advisory business. Most projects are priced
on a fixed-fee basis, plus expenses, with a limited number of projects priced on
a per-diem rate basis. The majority of project clients are also (or become)
retainer advisory clients. The revenue is less predictable than retainer
advisory revenue. It also can be more affected, year-to-year, by singular,
non-recurring large projects. The revenue is recognized, on a
percentage-of-completion basis, over the course of the project. In the fiscal
year ended June 30, 1997 ("Fiscal 1997") revenue from applications and
consulting projects decreased 7%, compared to increases of 10% and 66%,
respectively, in the prior two fiscal years. Project revenue was 27%, 34% and
39% of total revenue in the fiscal years ended June 30, 1997, 1996 and 1995,
respectively.

         Retainer-related revenue encompasses several activities, including
separately-charged presentations and consulting days, individual sales of
research reports, fees for attending CERA events, and major, multi-client
sponsored research studies. Revenue from these activities, which are all,
generally, connected to the retainer advisory business (with respect to content,
staffing and clients) increased 48%, 93% and 23% in the fiscal years ended June
30, 1997, 1996 and 1995, respectively. This revenue, which has increased
principally as a result of higher sales of multi-client research and scenarios
reports, represented 20%, 16% and 11% of total revenue in the fiscal years ended
June 30, 1997, 1996 and 1995, respectively.

         CERA has, historically, distributed all of its earnings in the form of
bonuses to its directors, employees and consultants. CERA has had S-corporation
status under the Code whereby CERA's earnings, if any, are passed through to
CERA's stockholders and taxed on an individual, rather than corporate, basis. It
is a fairly common practice for service companies (which, generally, may not
require large amounts of working capital) that are S-corporations to operate in
this manner (i.e., to have minimal amounts of reported net earnings).


                                       90
<PAGE>   93
         Staff compensation and benefits, including employee and consultant
bonuses (but excluding the bonuses distributed to CERA's stockholders) have
represented approximately two-thirds of operating expenses in each of the last
three fiscal years ended June 30, 1997, 1996, and 1995. These staff-related
expenses have increased at annual rates of 21%, 30% and 39% in each of the
fiscal years ended June 30, 1997, 1996 and 1995, respectively. The higher
expense has been largely the result of staff expansion over the past three
years, during which period the number of employees increased from 72 at the
beginning of the fiscal year ended June 30, 1995 ("Fiscal 1995") to 158 at the
end of fiscal 1997. The rate of staff expansion is expected to moderate in the
next fiscal year. The other one-third of operating expenses consists mainly of
travel costs, rent and other occupancy expenses, printing and communications.
These expenses have increased at annual rates similar to the staff expenses.

RESULTS OF OPERATIONS

         Three Months Ended September 30, 1997 versus 1996

Revenues

         Revenue increased 41%, from $5.8 million in the three months ended
September 30, 1996 to $8.2 million in the three months ended September 30,
1997. Retainer services revenue increased 37%, from $3.3 million to $4.6
million, due, primarily, to the recognition of revenue from new services sold
in Fiscal 1997. Revenue from applications projects increased 26%, from $1.7
million to $2.2 million, a result, primarily, of a larger backlog of sold, but
unfinished, projects, at June 30, 1997 compared to June 30, 1996.
Retainer-related revenue increased 95%, from $0.7 million to $1.7 million. This
is mainly because of increased revenue from special reports and multi-client
studies, up 53% from $0.5 million to $0.8 million, and a significant increase
in revenue from presentations and small consulting engagements, which are up
from $0.2 million in the three months ended September 30, 1996 to $0.6 million
in the three months ended September 30, 1997.

Expenses

         Total expenses increased 27% or $1.6 million, from $5.9 million to
$7.5 million, in the three months ended September 30, 1997 compared to the
three months ended September 30, 1996. More than half of the increase was due
to merger-related expenses and an interim charge to accrue for employee bonuses
(which are not paid until after the end of the fiscal year). Merger-related
expenses, up $0.35 million from $0.1 million to $0.45 million are included in
Other Income (expense), net, in the Consolidated Statements of Income. The
bonus expense was $0.5 million in the three months ended September 30, 1997.
There was no bonus expense in the prior year's first quarter. All other expenses
are up 13% or $0.7 million in the quarter, from $5.8 million to $6.5 million
because of higher staff expenses, up 17% or $0.5 million from $3.2 million to
$3.7 million, plus increased communications and depreciation expenses.

Net Income

         Net income for the three months ended September 30, 1997 was $0.6
million compared to a loss of $0.1 million in the three months ended September
30, 1996. Income from operations was $1.1 million in the three months ended
September 30, 1997, up from $21,000 in the  same period in the prior year. The
improved results are, essentially, due to revenue growth of 41%, which exceeded
the rate of increase, 27%, with expenses. As indicated, expenses other than
merger-related expenses or the provision for bonuses, increased 13%. This
reflects a reduction in the rate of increase in staff expenses, as well as the
absence in the three months ended September 30, 1997 of $0.2 million in
expenses for a client-service event which was incurred in the first quarter in
the prior year.

         Fiscal Year Ended June 30, 1997 versus 1996

Revenues

         Total revenue increased 18%, from $25.4 million in the fiscal year
ended June 30, 1996 ("Fiscal 1996") to $30.0 million in Fiscal 1997. Retainer
services revenue increased 26%, due, in part, to new advisory services covering
Asia Pacific Energy, Global Electric Power, and Oil and Gas Information
Technology Strategy. Revenue from applications and custom consulting projects
decreased 7%, primarily because Fiscal 1996 included revenue from a large,
multi-year applications project in Europe which was completed in Fiscal 1996.
This decrease was offset by increased sales of special reports (up 42%), and
increased revenue from the CERA Executive Conference and other client-service
events (up 115%).

                                       91
<PAGE>   94
Expenses

         As in prior periods, CERA distributed substantially all of its earnings
to its directors and employees in the form of bonuses. For Fiscal 1997, bonuses
were $3.7 million compared to $4.7 million in Fiscal 1996. Included in the $3.7
million in Fiscal 1997 is $1.9 million in bonuses related to the Merger and the
Exchange. Total expenses, excluding bonuses, increased 27% in Fiscal 1997
compared to Fiscal 1996. The increase in expenses was largely due to personnel
costs, up 27%, because of staff additions and increased use of Senior Associates
(contract research and consulting professionals) to generate and support
increased revenues. Expenses also increased because of a significant increase in
non-operating, merger-related expenses. Operating expenses, excluding bonuses,
for Fiscal 1997 are up 25%. Expenses also rose as a result of increased
international travel, particularly to Asia (CERA introduced a new Asia service
during this period), higher telecommunications expense, and increased rent due
to office expansion.

         Other expenses (non-operating) of $1.0 million were incurred by CERA in
Fiscal 1997 in connection, primarily, with the Merger and Exchange. In Fiscal
1996, $0.4 million was incurred in connection with CERA's review of potential
strategic merger partners.

Net Income

         Net income for Fiscal 1997 and Fiscal 1996, $2,744 and $7,523,
respectively, is nominal and has no particular significance because CERA has
distributed substantially all of its earnings in the form of bonuses. Income
before bonuses was $3.7 million in Fiscal 1997 compared to $4.7 million in
Fiscal 1996; the decrease due, primarily, to the merger-related expenses noted
above and increased staff expenses.



                                      92
<PAGE>   95
         Fiscal Year Ended June 30, 1996 versus 1995

Revenues

         Total revenue increased 27%, from $20.1 million in Fiscal 1995 to $25.4
million in Fiscal 1996. Revenue increased in all of CERA's product lines with
particularly high growth in the World Oil, and Latin America (which was
introduced in Fiscal 1995) services. Retainer services revenue increased 25%.
Revenue from applications and custom consulting projects increased 10%. Report
sales (scenarios, multi-client studies) increased significantly, from $0.7
million in Fiscal 1995 to $2.3 million in Fiscal 1996. A large applications
project in Europe, which began in 1994, continued through Fiscal 1996, and a
new, major (multi-year) applications project was begun in Fiscal 1996.

Expenses

         CERA has historically distributed substantially all of its net earnings
each year to its directors, employees and consultants in the form of bonuses. In
Fiscal 1996, these bonuses, which are included in operating expenses (in cost of
revenues, and selling, general and administrative expenses) were $4.7 million,
compared to $4.0 million in Fiscal 1995. Operating expenses, excluding bonuses,
increased 31% in Fiscal 1996 over Fiscal 1995, to $20.3 million from $15.5
million in Fiscal 1995. The increase in operating expenses was due, primarily,
to a 29% increase in personnel expenses (compensation and benefits), which,
generally, comprise approximately 60% of CERA's operating expenses (excluding
bonuses). The increased personnel expenses were due to a significant staff
expansion in Fiscal 1996 (to 143 employees, up from 98 at the end of Fiscal
1995). The staff additions were primarily in research, consulting and marketing,
and were needed to support CERA's continued revenue growth and in anticipation
of several new services planned for introduction in Fiscal 1997. Other operating
expense (non-personnel) increased 35%, primarily due to higher travel and
communications (network) expenses, and a major expansion of CERA's annual
Executive Conference and client Roundtables.

         Other expenses (non-operating) of $0.4 million were incurred for CERA's
ongoing review of potential strategic merger partners.

Net Income

         Net income decreased to $7,523 in Fiscal 1996 from $34,104 in Fiscal
1995. This decrease is not significant in that CERA had distributed
substantially all of its earnings in the form of bonuses. Net income before
bonuses increased to $4.7 million in Fiscal 1996 from $4.0 million in Fiscal
1995 due, primarily, to increased revenues in Fiscal 1996.



                                       93
<PAGE>   96


LIQUIDITY AND CAPITAL RESOURCES

         Net cash flow from operating activities was a negative $0.7 million
for the three months ended September 30, 1997, due, primarily, to the payment
of $1.8 million in employee bonuses related to the Fiscal 1997. CERA,
historically, has had negative or minimal net cash flow in its fiscal first
quarters because the annual payments of employee bonuses have been made during
these periods. Capital expenditures of $0.2 million, consisting, primarily, of
computer systems and equipment, were made in the three months ended September
30, 1997 compared to $0.3 million in the same period in the prior year. CERA
did not borrow any amounts under its $1.75 million line of credit with a bank
in the three months ended September 30, 1997, and there were no borrowings
outstanding to the bank (or to any other lender). CERA's cash balance at
September 30, 1997 was $4.0 million, and included $1.9 million reserved for the
payment of bonuses related to the Merger and the Exchange.

         In Fiscal 1996 and Fiscal 1995, CERA's cash flows from operations were
$0.4 million, and ($0.5) million, respectively. As indicated above, CERA has,
essentially, distributed all of its income in the form of bonuses to its
directors, employees and consultants. Operating cash flows, without bonuses
(which are all discretionary) in Fiscal 1996 and Fiscal 1995 were $4.5 million
and $3.2 million, respectively.

         In Fiscal 1997 and Fiscal 1996, CERA's cash flows from operations were
$5.4 million and $0.4 million, respectively. Operating cash flows, without
bonuses, in Fiscal 1997 and Fiscal 1996 were $7.5 million and $4.5 million,
respectively.

         In Fiscal 1995, CERA paid a special dividend of $0.2 million to
stockholders, to reimburse them for income taxes they had incurred on behalf of
CERA (because of CERA's S-corporation status under the Code). Also, in Fiscal
1995, CERA received $2.8 million in connection with a transaction in which
Goldman acquired a ten percent ownership interest in CERA LP. The $2.8 million
was distributed, as a special dividend, to CERA's stockholders.

         Capital expenditures were $1.1 million, $0.5 million and $0.4 million
in Fiscal 1997, Fiscal 1996 and Fiscal 1995, respectively. CERA's capital
spending is, primarily, for computer equipment, systems and software.
Expenditures increased in Fiscal 1997 because of purchase and development costs
of new research and marketing database systems which totaled $0.5 million.
Capital expenditures have been funded from operations.

         CERA has a $1.75 million, secured line of credit with a commercial
bank. In Fiscal 1997, Fiscal 1996 and Fiscal 1995, there were no borrowings
under this line of credit (or from any other sources). CERA's operating costs,
primarily staff compensation and benefits, are funded from operating cash flow.
CERA believes that it will continue to be able to fund its operating costs and
capital expenditures adequately from cash generated by operations.

         CERA has not had significant foreign exchange exposure. It invoices
substantially all of its clients in U.S. dollars, and incurs the majority of its
expenses in U.S. dollars. CERA does not have significant assets or liabilities
denominated in foreign currencies.

         All of CERA's cash, and cash equivalent, balances are maintained in
accounts with commercial banks or in a money market account at a large financial
institution.

                             BUSINESS OF THE PARENT

         Upon consummation of the Merger and the Exchange, the Parent's primary
assets will be the equity of MGI and CERA. As a result, the business of the
Parent will consist of the business of MGI and the business of CERA.


                                 BUSINESS OF MGI

OVERVIEW

         The Company

         MGI provides up-to-the-minute information and analysis relating to
developments in the U.S. and international corporate securities, fixed income
and currency markets to over 2,400 institutional clients in over 57 countries.
MGI's primary services include CorporateWatch(R), which is a leading provider of
up-to-the-minute information regarding the new issue corporate securities
market; MoneyWatch(R), which provides on-going analysis of developments in the
U.S. Treasury, agency and money markets; CurrencyWatch(R), which provides
analysis of intraday developments in the foreign exchange markets; and
YieldWatch(R), which analyzes intraday developments in the European and Asia
Pacific government bond and money markets. MGI recently introduced three other
services: FX OptionWatch(TM), which provides fundamental and technical analysis
of global currency option markets; TradeWatch(R), which provides longer term
trading recommendations for government securities, currencies, equities,
commodities and other financial instruments; and KinriWatch(TM), a Japanese
language service that provides fundamental and technical analysis of the
Japanese government bond and money markets.

         MCM was established in New York in 1975 and acquired in 1985 by VK/AC's
predecessor. In 1980, MCM entered into an agreement with DJM to distribute
MoneyWatch(R) on-line, a decision that reflected the market demand for quicker
updates on, and analysis of, Federal Reserve Board policy bearing on U.S.
Treasury, agency and money markets. In 1982, MCM launched its second
screen-based service, CorporateWatch(R), which covered new issues of corporate
debt and equity in the United States.

         MCM established an office in London in 1986 as the first step in a
strategy to expand its coverage of the integrating global financial markets.
Also in 1986, MCM launched its third screen-based service, YieldWatch(R), which
provides technical analysis and trading recommendations on some of the major
non-U.S. fixed-income markets. In 1987, MCM launched CurrencyWatch(R), which
proved very popular in large dealing rooms in London and continental Europe. In
1988, MCM and Fuji Xerox Co., Limited, established MCM Asia Pacific, 85% of
which is owned by MCM, to cover the principal financial markets in East Asia. In
1991, MCM sold its credit analysis and ratings division to Duff & Phelps
Investment Research Co. to concentrate on its electronic research services
business, and in 1992 MCM purchased Fintrend, S.A. (whose name has been changed
to McCarthy, Crisanti and Maffei, S.A.), further expanding its coverage of the
currency markets in Europe. Finally, in recognition of the increasing importance
of its London office, MCM established MCM Europe in early 1996, where
CurrencyWatch(R), YieldWatch(R) and FX OptionWatch(TM) are managed.

         Having offices staffed with analysts in the major financial centers
around the world has been an essential part of MGI's strategy for the last
decade. Currently, MCM and its subsidiaries produce and distribute electronic
information services worldwide, with offices in New York, Boston, London, Paris,
Tokyo, Hong Kong and Singapore.

         MGI believes there are attractive growth opportunities in the financial
information services sector of the foreign exchange and global fixed income
markets and that it is well positioned to take advantage of these opportunities.

         The Electronic Financial Information Services Industry

         The electronic financial information services industry encompasses
providers of a range of real-time financial information delivered through
digital feeds to computer workstation screens of financial market participants
that subscribe for those services. This financial information includes basic
data such as market quotes, financial news and historical information, as well
as high-value-added information such as market and technical analyses, research,
commentary and forecasts. Providers of such high-value-added financial
information first emerged in the late 1970s and early 1980s, primarily in
response to the strong demand for analysis and interpretation of the monetary
policy of the Federal Reserve Board. Because of their independence from
underwriters and brokerage firms and the quality of their services, a small
number of these providers established credibility with the markets in the
volatile interest rate environment of the early 1980s. Their services became,
for many clients, the functional equivalent of a high-quality, inexpensive,
in-house research department. The customers for these higher-value-added
services were primarily the trading and sales desks of institutional
participants in the U.S. fixed-income markets.

         Until the mid-1980s, the financial markets were focused primarily on
the U.S. fixed-income markets and Federal Reserve Board policy. Following the
peak in the relative value of the U.S. Dollar in 1985, however, the financial
markets became increasingly interested in non-U.S.-Dollar-denominated assets, a
trend which has increased with time. Providers of high-value-added services
responded by offering services to meet this demand. The customer base for these
services are now primarily the trading and sales desks of institutional
participants in the global markets.

         Business Strategy

         Subscription revenues for MGI's services have grown at a compound
annual rate of 20.5% from December 31, 1993 to December 31, 1996, which MGI
attributes to the quality of its research services, the expansion of its
coverage of global fixed income and foreign exchange markets, a shift to a
multi-vendor distribution system and a general increase in demand for financial
information services resulting from increased activity in the global financial
markets.

         MGI intends to maintain its strong growth in subscription revenues by
strengthening relationships with its Vendor Distribution Firms, increasing
market share for its existing services, identifying new services to market on
the strength of its brand recognition and reputation and preparing for
distribution through the Internet.

- -        Strengthen Relationships with Vendor Distribution Firms. Historically,
         MGI distributed its research services almost exclusively through DJM.
         Beginning in late 1993, MGI has pursued a non- exclusive distribution
         strategy with DJM and the other Vendor Distribution Firms, including
         Reuters, Bloomberg, Bridge, ADP and Quick. MGI believes that
         maintaining its historical relationship with DJM and strengthening its
         relationship with the other Vendor Distribution Firms is a key
         component in expanding revenues and market share. See "MGI Management's
         Discussion and Analysis of Financial Condition and Results of
         Operations" above and "--Distribution of Services" below. However,
         there can be no assurance that MGI's strategy will continue to be
         successful.

- -        Increase Market Share of Existing Services. In conjunction with its
         strategy of increasing market penetration by strengthening its
         relationships with Vendor Distribution Firms, MGI will continue to
         pursue an aggressive global marketing strategy that includes using
         analysts in marketing efforts

 
                                       98
<PAGE>   101
         and sharpening the design and content of its services. However, there
         can be no assurance that MGI's efforts to increase the market share of
         its primary existing services will be successful.

- -        Identify Market Opportunities and Launch New Services. To capitalize on
         MGI's global distribution system and coverage, MGI has actively
         explored, and intends to continue to identify and develop, new market
         opportunities in the continuously evolving global financial markets and
         the design and launch of services that build on MGI's success and
         reputation in the marketplace. The proposed combination with CERA is
         one of the results of this strategy. MGI may consider further strategic
         acquisitions or further hiring of key personnel as it continues to
         pursue opportunities to expand its business.

- -        Prepare to Expand through the Internet. In preparation for developments
         in Internet-related technologies, MGI is evaluating the distribution of
         MGI's existing services over the Internet and the development of new
         services specifically designed for distribution over the Internet.
         However, any such delivery of services over the Internet will depend on
         technological developments in the speed, reliability and security of
         data transmission and the emergence of demand for such services.

SERVICES

         MGI's primary services are as follows:

- -        CorporateWatch(R)is the leading provider of up-to-the-minute
         information relating to new issues in the corporate securities market.
         It is marketed to corporate sales departments, trading personnel and
         portfolio managers of financial institutions, primarily in the United
         States. CorporateWatch(R) covers the U.S. fixed income markets (fixed
         income filings, high-yield markets, preferred stock issuances, U.S.
         agencies, fixed-income deals, private placements, Yankee bonds),
         structured finance markets (asset-backed, whole loan issues,
         collateralized mortgage obligations and commercial mortgages) and
         international new issues, and provides commentary and analysis on a
         number of segments of these various markets.

- -        CurrencyWatch(R)is a research service that provides fundamental and
         technical analysis of intraday developments in the global foreign
         exchange markets and is marketed to foreign exchange dealing operations
         worldwide. CurrencyWatch(R)covers the market 24 hours a day, providing
         foreign exchange dealers with trading recommendations for the U.S.
         Dollar versus eight other currencies and nine key cross-rates, which
         are placed in context by a series of technical indicators and
         explanatory text. In addition, CurrencyWatch(R)covers the European
         Monetary System with commentary and data (including each EMS currency's
         cross rate against the Deutsche Mark, the cross-rate band limits for
         each currency and percentage movement of allowable divergence against
         the ECU), provides regional market briefings and recaps and other
         services.

- -        YieldWatch(R) is a research service that analyzes intraday developments
         in the global government securities markets and is marketed primarily
         to dealers in non-U.S. government bonds, primarily in Europe.
         YieldWatch(R) provides live commentary and technical analysis of short-
         and long-term yield curve spreads in the major fixed-income markets
         around the world.

- -        MoneyWatch(R) is a research service that provides ongoing fundamental
         and technical analysis of developments in the U.S. Treasury, agency and
         money markets, including analysis of economic data and Federal Reserve
         Board policies bearing on these markets. MoneyWatch(R) is marketed to
         traders, portfolio managers and certain credit analysts and foreign
         exchange traders in the United States and abroad.


                                       99
<PAGE>   102
         Recently MGI launched three new services that target participants in
identifiable market niches. FX OptionWatch(TM), which provides fundamental and
technical analysis of global foreign exchange option markets, was launched in
the first quarter of 1996. FX OptionWatch(TM) targets participants in the
options segment of the foreign exchange markets and was designed to complement
CurrencyWatch(R). FX OptionWatch(TM) provides trading recommendations,
strategies, moving averages and technical chartpoints that identify the key
issues bearing on volatility in different currencies. KinriWatch(TM), a Japanese
language service that provides fundamental and technical analysis of Japanese
government bond and money markets, was launched in the first quarter of 1996 and
was designed to be responsive to the preferences of the Japanese markets.
Originally available only through Quick, MGI expanded the distribution of
KinriWatch(TM) recently through Reuters and intends to expand the distribution
of KinriWatch(TM) in the near term through other Vendor Distribution Firms,
including Bloomberg and DJM. TradeWatch(R), which provides longer term trading
recommendations for government securities, foreign exchange, equities,
commodities and other financial instruments, was launched in the fourth quarter
of 1995 and was designed to take advantage of one of MGI's greatest
strengths--the quality and reputation of MGI's economists and analysts. MGI has
targeted portfolio managers in the existing base of institutional clients for
this service, who generally have not subscribed for real-time research services
such as those provided by MGI because of their longer term, investment-oriented
objectives. New service launches are inherently uncertain of success, and there
can be no assurance that MGI's strategy to identify new market segments and
design and launch new services will be successful. MGI does not expect to expend
material resources in promoting the launch of these services.

DISTRIBUTION OF SERVICES

         The traditional distribution channels for financial information are the
Vendor Distribution Firms, which charge a basic site fee and additional fees
based on the services subscribed for and delivered to each computer screen in a
financial institutional client. For many years most financial information
relating to U.S. dollar-denominated assets was distributed over DJM, which was
the first Vendor Distribution Firm to carry services provided by MGI and its
major competitors, MMS International and Technical Data Corporation. In late
1993, MGI made the strategic decision to develop non-exclusive distribution
relationships with every major Vendor Distribution Firm. The following chart
demonstrates the number of screens available to it through the Vendor
Distribution Firms.

         MGI is also monitoring developments in the Internet-related industries,
a potentially significant distribution channel in the future that could allow
dial-up retrieval of MGI's services. See "--Overview--Business Strategy" above.

SUBSCRIPTION AGREEMENTS

         Virtually all of MGI's revenues are derived from subscription
agreements with its customers. Subscription agreements with U.S.-based customers
are generally made directly between those customers and MGI and may be either
oral or written agreements. Oral agreements with U.S.-based clients are
generally terminable upon 90 days' notice without penalty. Written agreements,
which represented approximately 18.7% of MGI's U.S. revenues in 1996, typically
have a one-year term but are not subject to early termination.

         Non-U.S.-based clients subscribe by means of service agreements entered
into with the Vendor Distribution Firms, pursuant to which a subscriber can
elect to subscribe for various optional services, including MGI's services. With
certain exceptions, such agreements are written and typically have one- or
two-year terms that renew automatically unless the subscriber provides 90 days'
prior notice of non-renewal.

MARKETING

         MGI has an experienced team of marketing, sales and client support
personnel. The staff of 33 professionals in the United States, Europe and Asia
Pacific is responsible for securing, expanding and maintaining client
relationships, pricing, promotions and identifying new product opportunities.

CUSTOMERS

         No subscriber accounts for more than 2% of MGI's revenues. Subscribers
to MCM's electronic information services consist almost exclusively of
institutional clientele (e.g., major banks, brokers, dealers, government bond
and financial futures trading operations, foreign exchange trading operations,
and treasury departments of major corporations).

EMPLOYEES

         At September 30, 1997, MGI had 103 full-time employees (including both
professional and support staff). None of these employees is a member of a union.

COMPETITION

         MGI competes in the high-value-added segment of the financial
information services industry against both well-established and smaller
companies, some of which may have substantially greater resources than MGI and
offer a broader array of services. The Vendor Distribution Firms distribute
numerous competing services, including their own or their affiliates'
proprietary services and the services offered by MGI's primary competitors.
Currently, MGI's primary competitors are MMS International, owned by
McGraw-Hill, and Technical Data Corporation, owned by Thomson Corporation.

         Competition is based on various factors, including the breadth of
coverage, availability of both fundamental and technical analyses, the frequency
and number of intra-day updates, the range, quality, timeliness and accuracy of
information, the ability to filter, retrieve, manipulate and store information,
the level of fees charged, customer service, the success of marketing and sales
efforts and the subscribers' preference among the Vendor Distribution Firms.
Currently, there are relatively few barriers to entry by


                                       101
<PAGE>   104
new on-line service providers, although the lack of name recognition and access
to a Vendor Distribution Firm may make entering the business more difficult for
potential competitors.

         Competition is expected to increase as technological advancements
improve the speed and reliability of delivery and retrieval of information
supplied over the Internet, which could emerge as an inexpensive distribution
alternative to the high-cost, proprietary networks offered by the Vendor
Distribution Firms. At present, the relatively slow rate of transmission of data
over the Internet, questions about the reliability of Internet service
providers' systems and concerns over the security and integrity of data
delivered over the Internet serve as technological impediments to the
effectiveness of the Internet as a distribution channel for services such as
those provided by MGI. If technological advancements enabling faster, more
reliable and secure delivery of digital data occur, the Internet could emerge as
a significant distribution channel for financial information, including the
high-value-added services such as those provided by MGI. Because access to the
Internet is inexpensive and requires relatively inexpensive equipment and
software, such technological advancements could allow the Internet to emerge as
an alternative to the Vendor Distribution Firms and therefore reduce one of the
most significant entry barriers to start-up--i.e., access to the Vendor
Distribution Firms. While MGI is taking preliminary steps to respond to
developments in Internet-related technologies and industries, there can be no
assurance that increased competition resulting from the emergence of the
Internet as an effective, low-cost distribution channel would not have a
material adverse effect on MGI.

FACILITIES

         MGI, which is headquartered in New York, New York, conducts its
business through leased office space there and in Boston, London, Paris, Tokyo,
Hong Kong and Singapore. MCM's lease for approximately 29,000 square feet in its
New York (the "New York Office Lease") headquarters expires in year 2009. MGI
also leases over 14,000 square feet for additional office space for its
operations. MGI also intends to enter into a lease for an additional 3,000
square feet of office space in London. MGI believes that these facilities are
adequate to serve its currently anticipated business needs.

         Van Kampen American Capital Distributors, Inc., a wholly owned

amount of tax liabilities or benefits attributable to MGI, MCM or any of its
subsidiaries is to be determined as if MGI, MCM and its subsidiaries had filed
their income tax returns on a stand-alone basis. The Tax Sharing Agreement will
not have any effect on the payment of taxes with respect to which MGI, MCM and
its subsidiaries have historically filed returns on a stand-alone basis.

LEGAL AND RELATED MATTERS

         MGI is not involved in any material proceeding, other than routine
litigation incidental to its business.

                                BUSINESS OF CERA

OVERVIEW

         CERA is a leading international advisory and consulting firm that
focuses on the energy industries, including markets, geopolitics, structure and
strategy. CERA's independent expertise and perspective assist its clients in
making informed strategic, investment and market decisions in the energy
industry. CERA's expertise covers major global and regional energy sectors--oil,
refined products, natural gas and electricity. CERA delivers services through
retainer advisory services, a series of subscription-based continuous retainer
advisory services, consulting, applications, and related services that draw upon
its unique industry expertise.

         CERA's family of retainer advisory services provide a continuous
analysis of energy markets, industry trends and strategies. Each retainer
advisory service focuses on a key energy segment or region, including World Oil,
Refined Products, North American Natural Gas, North American Electric Power,
European Natural Gas, European Electric Power, Former Soviet Union Energy, Latin
American Energy, California Energy and Asia Pacific Energy. CERA also offers
membership services aimed at specific professional communities. These include
the Global Power Forum and the Oil and Gas Information Technology Strategy
Forum, which provide clients with dialog, interaction and collaboration in
matters affecting the power and oil and gas industries, respectively.

         CERA applies its strategic knowledge and in-depth analysis expertise in
the energy industry to provide consulting and advisory services, including
strategic and scenario planning, organizational and market studies, and other
focused consulting activities. In addition, CERA multiclient studies provide
assessments of major energy developments and specific markets.

INDUSTRY BACKGROUND

         The energy industry is one of the world's largest industries and is
essentially a global industry. CERA believes that the global energy industry is
of important strategic significance to the international economy and is subject
to significant change and influence relating to, among other things, political
forces, globalization, privatization, environmentalism and competitive
pressures. The industry, including its oil, gas and electric power segments, is
subject to considerable volatility. In addition, CERA expects vast amounts of
capital to be expended in the energy industry, including, for example,
expenditures related to the rehabilitation of the Russian oil industry, ensuring
sufficient energy supplies and infrastructure in Asia to support economic
growth, restructuring the electric power business in the U.S. and overseas, new
technologies and compliance by oil refiners with existing and new environmental
regulations.

         The pace of change around the world in both developed and developing
countries and economies makes strategic information of significant value to
decision makers. The increasingly global nature of these trends requires
extensive capabilities and expertise to obtain, assimilate and analyze critical
information and data and to develop insights into the industry's future. In
addition, CERA believes that the ability to integrate economic and political
analyses with global energy expertise is particularly useful.

         CERA also believes that there is a need for the efficient development
of energy resources in an environmentally-sensitive manner to support economic
growth, which has been highlighted by the transition of the world's energy
industry from the public to the private sector in formerly state-run economies.
The emerging global private power business is an example, as is the transition
in the former Soviet Union. The trend toward privatization began in Europe in
the 1980's with the deregulation of energy markets and privatization of formerly
state- controlled enterprises. Privatization has also commenced in Latin America
as a source for financial resources and as the need for operating efficiencies
has become apparent. This is creating new companies requiring objective
information and analysis on energy. It is also creating a need among existing
industry

                                       104
<PAGE>   107
participants for enhanced strategic knowledge and information on global and
regional energy markets. CERA believes that the growth of economic activity in
developing countries can only be sustained with access to additional energy
sources.

         CERA believes that these circumstances create a market for strategic
information that will allow businesses to make short- and long-term decisions
relating to the energy industry.

CERA SOLUTION

         CERA's products and services provide a continuous analysis of energy
markets, industry trends and strategies. This analysis creates a framework that
allows clients to identify key forces, uncertainties and price movements that
may affect certain fundamentals in key energy sectors and markets around the
world. CERA provides an assessment of the economic and geopolitical factors, as
well as key governmental policies and changes in political attitudes, affecting
supply and demand, prices and investment opportunities in the energy industry.

         CERA's retainer advisory membership services provide clients with
continuous analysis of energy markets, industry trends and strategies, covering
the key energy segments and regions around the world. In addition, CERA's
applications and consulting services provide solutions to client specific needs
by utilizing strategic knowledge and in-depth analysis of the energy industry
and the factors affecting such industry. Through its membership forums, CERA
promotes dialogue, interaction and collaboration concerning developments in the
energy industry. CERA's multiclient studies provide assessments of major energy
developments and specific markets. Scenarios developed by CERA's research
retainer service provide clients with an overall framework for anticipating and
understanding change in global and regional business environments.

CERA STRATEGY

         CERA's strategy is to become a leading provider of insights and
strategic knowledge on the global energy market. CERA seeks to do the following:

         -        Maintain Research and Analysis Excellence. The quality of its
                  research organization is critical to CERA's ability to provide
                  value to its customers. CERA seeks to attract, develop and
                  retain outstanding research professionals with expertise in a
                  broad range of energy industry disciplines. In order to
                  capture a worldwide energy industry perspective, CERA has
                  developed a global network of research analysts.

         -        Expand Client Base and Maintain High Retention Rates. CERA
                  seeks to increase the number of retainer advisory memberships.
                  CERA believes that its current offerings of products and
                  services, and anticipated new products and services, can
                  continue to be successfully marketed and sold to new clients,
                  as well as new constituencies within existing client
                  companies. CERA also seeks to maintain or improve its 90%
                  client retention rate through continued implementation of
                  additional retainer advisory services and broad research
                  coverage. In addition, CERA's research is available via the
                  World Wide Web. CERA believes that improvements in
                  distribution technology will enable it to expand
                  constituencies within existing client organizations as well as
                  to expand its client base. However, there can be no assurance
                  that CERA will be able to sustain such a high client retention
                  rate or that CERA's strategy will continue to be successful.
                  In addition, CERA's pricing strategy may limit the potential
                  market for CERA's services.

         -        Identify and Define New Products. CERA seeks to position
                  itself ahead of other research and advisory firms by
                  delivering strategic research and analysis on new and emerging
                  trends in the global energy industry, including in-depth
                  analysis of key fuels and all


                                       105
<PAGE>   108
                  geographical markets for energy. CERA believes that its
                  methodology and culture allow it to focus on the key fuels and
                  developments in the energy markets and enable it to expand its
                  product and service offerings to address these new
                  developments. However, there can be no assurance that CERA's
                  strategy will be successful.

         -        Leverage Core Research and Applications. CERA seeks to employ
                  expertise gained from the research that supports retainer
                  services to assist clients in specific applications. In
                  addition, CERA intends to continue to introduce new retainer
                  advisory membership services that build upon its expertise and
                  an understanding of needs of the industry. However, there can
                  be no assurance that CERA's strategy will be successful.

<PAGE>   109
         -        On-Site Presentations and Workshops--one-on-one interactive
                  sessions to present CERA analysis and discuss the implications
                  for the client company.

         Retainer advisory service members also receive CERA's global overview
research, which is intended to provide a broad, integrative framework concerning
economic and geopolitical trends affecting the energy industries. This global
research includes Global Energy Watch, a semiannual assessment of key strategic
energy trends and interfuel interactions, and reports on the changing dynamic of
the energy business. CERA members may also attend the CERA Executive
Conference--The Global Energy Forum, which is an annual gathering of senior
energy decision makers.

         MEMBERSHIP FORUMS. CERA has established two forums designed to promote
dialogue, interaction and collaboration based on a research agenda, which
includes specific research papers, that is managed and implemented by CERA.
These two forums are as follows:

                  The Global Power Forum. This forum brings senior decision
makers and ministers from business, government and financial communities
together for regular conferences. These conferences are designed to promote
dialogue and the exchange of views and help participants to understand
developments in the international power industry as well as regional
opportunities and related strategic implications.

                  The Oil and Gas Information Technology Strategy Forum. This
forum provides a strategic framework for assessing and benchmarking challenges
and opportunities created by information technology. Sessions also address the
potential impact of information technology on the structure of oil and gas
companies as well as competitive implications.

         APPLICATIONS AND CONSULTING SERVICES. CERA provides strategic and
scenario planning services, organizational and market studies, and other focused
consulting activities. Through specific client projects, referred to as
applications, CERA applies its strategic knowledge and in-depth analysis in the
energy industry to assist individual clients with particular needs. Assignments
typically focus on the following areas: scenario planning process and
facilitation; strategy development and implementation; corporate and business
segment strategy options; future skills and competencies; market analysis
(regional or industry); organizational analysis; restructuring and deregulation;
asset valuation; value chain analysis; strategic alliance/partnership
development; company profiling; post-merger strategic alignment and integration;
privatization; country assessment; business environment and scenario
development; implications for the client; expert witness; due diligence and
critical review of strategy and plans; and executive presentations and corporate
facilitation.

         MULTICLIENT STUDIES. Multiclient studies provide assessment of major
energy developments and specific markets. Clients are provided with a
cost-effective, high-value, decision-oriented analysis and a framework for
assessing critical issues. CERA offers these studies as written in-depth
reports, participant workshops and one-on-one company sessions. Examples of
multiclient studies include the following: The Race to Capture Value: The Future
of US Northeast Gas Markets; Transportation Dynamics: Understanding the Future
of Oil Flows in the Former Soviet Union; Natural Gas in Southeast Asia:
Scenarios for the Future of Gas Investment, Infrastructure Development, and the
Competitive Dynamics of the Energy Marketplace; The Future of Central European
Energy; and The New Energy Frontier: The Future of the Western Gas & Power
Markets.

         Most of CERA's retainer services develop multi-client scenario studies
to provide a long-term framework for anticipating and understanding change in
its focus area. Scenarios assist clients in anticipating and responding to
uncertainties and change in the global and regional business environment. CERA
believes that this approach allows decision makers to explore trends and forces
that will affect their business and to incorporate new ideas and information
into their thinking and strategic processes. Current CERA multiclient scenario
studies include the following: The Future of World Oil Markets: Scenarios to
2010;

RESEARCH AND ANALYSIS

         CERA's research and analysis group consists of approximately 68
full-time employees who provide ongoing research and analysis on the
developments, information and activities in the energy industry. Each of the
energy products and geographical regions covered by CERA is staffed by a team of
research analysts and associates with substantial experience and/or expertise in
the industry area covered by such products or regions.

         CERA employs a consistent, disciplined research and analysis
methodology across CERA's full product line, and issues printed or
electronically distributes material using a consistent presentation format. Each
energy product and geographical region has a product line research director who
is responsible for implementing CERA's research and analysis methodology in that
product area or geographical region. The development methodology consists of an
iterative process of research, analysis, hypothesis and testing. Analysts
conduct extensive primary research, working with CERA's client base and
contacting other sources. These activities are supplemented with searches of
numerous trade, financial and other third party source materials. From this
research, analysts identify significant patterns and trends, develop
assumptions, test hypotheses and arrive at concrete recommendations and
conclusions to provide to clients. CERA conducts its research and analysis on an
ongoing basis, continually retests its underlying assumptions and projected
scenarios as developments occur and highlights to clients material changes to
the assumptions, projections, recommendations and conclusions.

         The knowledge and experience of CERA's analysts is critical to the
quality of CERA's products and services. To ensure consistency of positions and
analysis across service and research disciplines, all CERA's distributed
research is reviewed by CERA's Head of Global Research. While varying opinions,
debate and philosophical contention among services and research disciplines are
encouraged, final positions and conclusions are consistent. This practice
ensures that the analytical structure and recommendations presented in CERA's
products are not inconsistent and better enables the various elements of client
organizations to formulate integrated strategies based on coherent information
and analysis.

SALES AND MARKETING

         As of December 31, 1997, CERA had 46 full-time employees in sales and
marketing in various locations worldwide. CERA's strategy is to optimize and
grow resources and coordinate sales and marketing across product lines and
geographical regions. Responsibilities among CERA's sales and marketing staff
are allocated as follows: sales staff have account-driven responsibility for
renewals, new retainer and application consulting sales within designated
industry segments and regions; marketing and product management staff have
accountability for product planning, development, pricing, promotion, quality
control, commercial database management, sales staff support and other
initiatives such as electronic distribution; and administrative and client
services staff handle processing of new clients, assistance with incoming
information requests, distribution of reports and other literature, written
research to clients and the delivery of corporate marketing materials. Three of
CERA's customers accounted, in the aggregate, for 28% and 20% of its total
revenues for the fiscal years ended June 30, 1996 and 1997, respectively.

CUSTOMERS

         As of December 31, 1997, CERA had a total retainer base of 
approximately 485 retainer contracts with various client organizations. Among
the client organizations that CERA serves are the following: integrated oil


                                      108
<PAGE>   111
companies and national oil companies; independent producers and refiners;
pipelines, tanker and transportation companies; electric and gas utilities and
independent power generators; banks, pension funds, institutional investors and
other financial institutions; manufacturing firms and large energy end-users;
government and regulatory agencies; trading, marketing and distribution firms;
oil services and supply companies; engineering and construction companies; and
legal and accounting firms servicing the energy industry. Three of CERA's
customers accounted, in the aggregate, for approximately 28% and 20% of its
total revenues for the years ended June 30, 1996 and 1997, respectively.

COMPETITION

         CERA believes that the principal competitive factors in its industry
include independence and quality of research, breadth of product offering, depth
of expertise, relevance and timeliness of information and its efficient
delivery, attention to customer service, effectiveness of sales and marketing,
credibility and reputation, global perspective and orientation, and adaptability
to the evolving information needs of clients. CERA believes that it competes
favorably with respect to each of these factors.

         CERA competes in the market for research and information on the global
energy industry. The Parent believes that the principal competitors for CERA's
business are the energy practices of the major management consulting firms,
independent energy consulting firms and information providers (such as brokerage
firms, consulting firms, publishing firms and smaller boutique firms
specializing in a particular energy industry sector or region). CERA's
competitors include Petroleum Economics Limited, Petroleum Finance Company and
PIRA Energy Group. There can be no assurance that CERA will be able to continue
to compete successfully against existing or new competitors.

EMPLOYEES

         As of December 31, 1997, CERA had 170 full-time employees (including 
both professional and support staff). None of these employees is a member of a
union.

FACILITIES

         CERA, which is headquartered in Cambridge, Massachusetts, conducts its
business through leased office space there and in Paris, France, Oakland,
California, Moscow, Russia, and Washington, D.C. CERA's lease for approximately
22,600 square feet in its Cambridge headquarters expires on June 3, 2000. CERA
also leases over 10,000 square feet for additional office space for its
operations. CERA has entered into a non-binding letter agreement with the
landlord of its Cambridge headquarters with respect to the leasing of additional
space by CERA for a period of five years beginning on January 1, 1998.

INTELLECTUAL PROPERTY

         CERA owns a number of trademarks and service marks associated with its
products and services, including the "CERA" mark.

LEGAL AND RELATED MATTERS

         CERA is not involved in any material proceeding, other than routine
litigation incidental to its business.

EMPLOYMENT AND OTHER AGREEMENTS

         In connection with the Spin-Off, MGI entered into employment agreements
with Mr. Nixon, Mr. Cook, Mr. Napolitano and Ms. Gell. The employment agreements
generally provide for a three-year term, and for compensation and benefit
arrangements that are consistent with the current compensation and benefit
arrangements of MGI. The employment agreements also provide that, in the event
of a termination of any such key employee's employment during the term of the
agreement by MGI other than for "Cause" (as defined in the employment
agreements) or by such key employee for "Good Reason" (as so defined), the key
employee will be entitled to special termination benefits consisting of (i)
continued salary generally for a period equal to the greater of (x) one year and
(y) the remaining term under the employment agreement, (ii) a pro rata incentive
bonus for the year of termination and (iii) continued welfare benefits,
generally for six months. The agreements also contain customary indemnification,
confidentiality, noncompetition and nonsolicitation provisions.

         CERA will enter into employment agreements with Daniel H. Yergin, James
P. Rosenfield and Joseph A. Stanislaw, which will replace the existing

anniversary of the Closing Date, for base compensation of $265,000, $255,000,
and $255,000 to Mr. Yergin, Rosenfield and Stanislaw, respectively, and for a
bonus based on the performance of CERA and MGI and the achievement of individual
goals. The employment agreements also provide that in the event of a termination
of the applicable employee's employment during the term of the agreement by CERA
"Without Cause" (as defined in the employment agreements) or by such employee
for "Good Reason" (as so defined), the employee will be entitled to special

The agreements also contain customary indemnification, confidentiality,
noncompetition and nonsolicitation provisions.

         Mr. Michelon serves as Managing Director, Operations of CERA pursuant
to the terms of a letter agreement regarding his employment with CERA dated July
2, 1993, as amended by a letter agreement dated February 24, 1995. The agreement
provides for a term of employment through September 1, 1998, provided that, such
term will be extended for additional two-year terms, unless either Mr. Michelon
or CERA provides twelve months' notice prior to the expiration of the current
term. If a controlling portion of CERA is merged or sold and Mr. Michelon's
employment is terminated by CERA without cause, the agreement provides for a
severance payment to Mr. Michelon in an amount equal to two times his then
current annual salary.

         CERA has entered into an agreement with Mr. Lucking which provides that
if, on or prior to December 31, 1998, his employment with CERA is terminated in
connection with the merger or sale of all or a controlling portion of CERA or
without cause subsequent to the merger or sale of all or a controlling portion
of CERA, he will receive a severance payment in an amount equal to his then
current annual base salary.

         MGI and CERA have entered into a Consulting Agreement, dated October
1, 1997, with Peter Derow. Pursuant to this Consulting Agreement, Mr. Derow has
agreed to provide general consulting, financial and managerial advisory
services to both MGI and CERA, as and when reasonably requested to do so by
either MGI or CERA. Mr. Derow will be paid a monthly fee of $50,000 in respect
of these services, with MGI and CERA each responsible for one-half of such fee.
The Consulting Agreement is terminable by any party upon 10 days prior written
notice.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         C&D Fund IV, which is MGI's largest stockholder and, following the
consummation of the Merger and the Exchange will be the Parent's largest
Unit holder, is a private investment fund managed by CD&R. Amounts contributed
to C&D Fund IV by its limited partners are invested at the discretion of
Associates IV, in equity or equity-related securities of entities formed to
effect leveraged buy-out transactions and in the equity of corporations and
other entities where the infusion of capital coupled with the provision of
managerial assistance by CD&R can be expected to generate returns on the
investments comparable to returns historically achieved in leveraged buy-out
transactions. Associates IV is the general partner of C&D Fund IV. Donald J.
Gogel, President and a shareholder of CD&R and a general partner of Associates
IV, serves as a director of MGI, MCM and the Parent.

         Pursuant to the Consulting Agreement, MGI pays CD&R an annual fee of
$150,000 for management and financial consulting services provided to MGI,
together with reimbursement of out-of-pocket expenses. Such services include
helping MGI to establish effective banking, legal and other business
relationships, and assisting management in developing and implementing
strategies for improving the operational, marketing and financial performance of
MGI. Such consulting fees are reviewed on an annual basis and will be calculated
with reference to the size and complexity of MGI's business, the type and
magnitude of the advisory and management consulting services being provided, the
fees being paid to CD&R by other companies for which it provides such services
and the fees charged by other managers with comparable organizations for similar
services provided to companies in which investment funds managed by such
managers have been invested. In connection with the consummation of the Merger
and the Exchange, CERA will become a party to the Consulting Agreement and CERA
and MGI will share the obligation to pay the fees and other amounts payable
thereunder.

         Pursuant to the Cribiore Services Agreement,in exchange for a fee equal
to the sum of the amount of any management fee paid to CD&R under the Consulting
Agreement (for so long as Mr. Cribiore serves as the Chairman of the Board of
each of MGI and MCM) and certain other amounts, Brera has been providing the
services of Mr. Cribiore to assist CD&R in providing managerial and financial
consulting services under the Consulting Agreement, among other matters. Brera
has made and may continue to make other Brera employees, including Mr. McMahon,
available to assist Mr. Cribiore in providing such services. In addition to the
assistance provided pursuant to the Cribiore Services Agreement, Brera has
provided financial advisory services to MGI with respect to the structuring and
negotiation of the Merger, the Exchange and related transactions, including the
financing thereof and certain executive compensation arrangements. The Brera
Options will be granted to Brera or its designees in return for such financial
advisory services. Mr. Cribiore is managing principal of Brera and Mr. McMahon
is principal of Brera.

         CD&R, C&D Fund IV and MGI are parties to an indemnification agreement,
pursuant to which MGI has agreed to indemnify CD&R, C&D Fund IV, Associates IV
and their respective directors, officers, partners, employees, agents and
controlling persons against certain liabilities arising under the federal
securities laws, other laws regulating the business of MGI and certain other
claims and liabilities. In connection with the Merger and the Exchange, CERA
will become a party to such indemnification agreement and will agree to
indemnify such persons and entities to the same extent as they are indemnified
by MGI.

         Messrs. Yergin, Rosenfield, Stanislaw and I. C. Bupp and Mr. Raymond
Vernon, a director of CERA until June 1997, entered into an indemnification
agreement, pursuant to which Messrs. Yergin, Rosenfield, Stanislaw and Bupp
agreed to indemnify Mr. Vernon against all expenses, judgments, fines and
penalties incurred by Mr. Vernon in the event that he was or is a party, or is
threatened to be made a party, to certain actions by reason of the fact that he
is or was a director or officer of CERA or any its affiliates. The agreement
also contains certain provisions which set forth the procedures for obtaining
indemnification. The term of the agreement shall terminate no earlier than three
years after the date on which Mr. Vernon ceased to be a director or officer of
CERA and any of its affiliates.

         Messrs. Yergin, Rosenfield, Stanislaw and Bupp and Mr. Edward G.
Jordan, a director of CERA until June 1997, entered into an indemnification
agreement, pursuant to which Messrs. Yergin, Rosenfield, Stanislaw and Bupp
agreed to indemnify Mr. Jordan against all expenses, judgments, fines and
penalties incurred by Mr. Jordan in the event that he was or is a party, or is
threatened to be made a party, to certain actions by reason of the fact that he
is or was a director or officer of CERA or any its affiliates. The agreement
also contains certain provisions which set forth the procedures for obtaining
indemnification. The term of the agreement shall terminate no earlier than three
years after the date on which Mr. Jordan ceased to be a director or officer of
CERA and any of its affiliates.

         In January 1995, CERA entered into a consulting arrangement with Mr.
Jordan, a director of CERA until June 1997. The arrangement provided for payment
to Mr. Jordan of $17,500, $35,000 and $35,000 in the fiscal years ended June 30,
1995, 1996 and 1997, respectively. In addition, CERA agreed to pay Mr. Jordan a
fee in respect of the transactions contemplated by the Merger Agreement. Mr.
Jordan has agreed to accept the Jordan Options in full payment of such fee.

         CERA has made loans to certain of its executive officers in amounts in
excess of $60,000 since the beginning of CERA's last fiscal year. In December
1997, CERA made loans to Messrs. Yergin, Rosenfield and Stanislaw in the amount
of $150,000, $50,000 and $150,000, respectively. In January 1998, CERA made
loans to Messrs. Yergin, Rosenfield and Stanislaw in the amount of $375,000,
$250,000 and $292,000, respectively. Each of Messrs. Yergin, Rosenfield and
Stanislaw is an executive officer of CERA. The largest aggregate amount of
indebtedness to CERA outstanding at any time since the beginning of CERA's last
fiscal year was $525,000, $300,000 and $442,000 for Messrs. Yergin, Rosenfield
and Stanislaw, respectively. These loans were made by CERA to these executive
officers in order to provide such individuals with the funds necessary to
satisfy their income tax liabilities. Each of the loans is evidenced by a
short-term demand note and bears interest at the rate of the lowest short-term
applicable federal rate as determined under Section 1274 of the Code. The amount
of indebtedness to CERA for Messrs. Yergin, Rosenfield and Stanislaw outstanding
as of January 15, 1998 was $525,000, $300,000 and $442,000, respectively.

                COMPARISON OF STOCKHOLDER AND UNIT HOLDER RIGHTS

         The rights of the holders of MGI Common Stock are currently governed by
the DGCL and by the MGI Certificate of Incorporation and By-Laws. The rights of
holders of MGI Class C Common Stock are also governed in part by the management
stock subscription agreements that each such holder has entered into with MGI.
As a result of the Merger, stockholders of MGI not exercising dissenters' rights
will become holders of units of capital representing limited liability interests
in the Parent, a Delaware limited liability company, and as such their rights
will be governed by the Delaware Act and by the Parent's Certificate of
Formation and the LLC Agreement. Certain differences arise from this change in
governing law as well as from distinctions between MGI's Certificate of
Incorporation and By-Laws and the Parent's Certificate of Formation and LLC
Agreement.


         The following summary does not purport to be a complete description of
the rights of holders of Units or the rights of holders of MGI Common Stock, or
a comprehensive comparison of such rights, and is qualified in its entirety by
reference to the DGCL, MGI's Certificate of Incorporation and By-Laws, and the
Parent's Certificate of Formation and the LLC Agreement.

GENERAL

         As a result of the Merger, the holders of MGI Common Stock (other than
stockholders exercising dissenters' rights) will become holders of Units and as
such their rights will be governed by the Delaware Act and by the Parent's
Certificate of Formation and the LLC Agreement, the form of which is attached as
Annex B to this Information Statement/Prospectus. As a result, certain rights
with respect to holders of MGI Common Stock will differ considerably from their
respective rights as Unit holders following the Merger. See "The Limited
Liability Company Agreement." In particular, the rights of holders of Units
will be subject to certain requirements not currently imposed upon holders of
MGI Common Stock, such as requirements with respect to the election of
directors, the vote required in order to authorize certain actions to be taken
by the Parent and the parties whose consent will be required in order to amend
particular provisions of the LLC Agreement. Also, Unit holders will not be
entitled to appraisal rights. The right of a Member (as defined herein) to
receive distributions from the Parent will also be somewhat different than the
right of a holder of MGI Common Stock to receive dividends and distributions
from MGI. Holders of MGI Common Stock are currently entitled to receive
equivalent per share dividends and other distributions from MGI if, as and when
declared by the Board of Directors of MGI. Members will also generally be
entitled to receive equivalent per Unit distributions from the Parent, except
that in the case of certain extraordinary distributions as a result of events
such as a sale or spin-off of MGI or CERA, certain adjustments will be made in
respect of the rights to receive Contingent Units if such Units have not yet
been issued. Distributions will be paid to Members at the discretion of the
Board of Directors of the Parent, except that the Parent will make
distributions, to the extent of available cash, necessary for holders of Units
to pay tax liabilities.

         The shares of Class A Common Stock and Class B Common Stock and the
Units will be subject to substantially similar restrictions on transfer,
including rights of first offer and take-along rights, except that prior to the
first underwritten public offering of Units after the Closing Date, the Units
will be subject to certain additional restrictions on transfer, which attempt to
prevent the Parent's being treated as a publicly traded partnership under the
Code. While the shares of Class C Common Stock are not currently subject to the
same restrictions on transfer that are imposed upon the shares of Class A Common
Stock and Class B Common Stock pursuant to MGI's Certificate of Incorporation,
all of the outstanding shares of Class C Common Stock are subject to substantial
restrictions on transfer as a result of the terms of the management stock
subscription agreements between MGI and each of the holders of such shares, and
these restrictions, including certain MGI and C&D Fund IV repurchase rights in
the event of the termination of the applicable holder's employment with MGI,
will continue to apply to the Units that are issued upon conversion of the
shares of Class C Common Stock in the Merger. In addition, such Units will be
subject to the same restrictions on transfer imposed on all Units pursuant to
the LLC Agreement. Holders of MGI Common Stock and holders of Units also will be
entitled to substantially similar participation and registration rights.

                                      121
<PAGE>   124
         In addition, although not generally required by law, the LLC Agreement
will impose certain fiduciary duties of care and loyalty on the Members,
Directors and Officers of the Parent that will generally be the same as those of
a stockholder, director or officer of a Delaware corporation, except that no
Member or Director of the Parent who is not also an employee of the Parent or
any of its subsidiaries will be required to present any particular investment
opportunity to the Parent even if such opportunity is of a character that, if
presented to the Parent, could be taken by the Parent.

MGI COMMON STOCK

         Voting Rights.

         Each holder of shares of Class A Common Stock and Class C Common Stock
is entitled to one vote per share on all matters to be voted on by stockholders.
Holders of Class A Common Stock and Class C Common Stock are not entitled to
cumulative votes in the election of directors. Any director may be removed at
any time, either for or without cause, upon the affirmative vote of the holders
of a majority of the outstanding shares of MGI's capital stock entitled to vote
for the election of such director, cast at a special meeting of stockholders
called for that purpose. C&D Fund IV, therefore, is able to effect the removal
of any director so long as C&D Fund IV holds a majority of the outstanding
shares of MGI's capital stock entitled to vote.

         Dividend Rights.

         The holders of MGI Common Stock are entitled to receive equivalent per
share dividends and other distributions if, as and when declared by the MGI
Board of Directors out of assets legally available therefor.

MGI CLASS A AND CLASS B COMMON STOCK

         Certificate of Incorporation.

         The Certificate of Incorporation of MGI provides that the shares of the
Class A Common Stock and Class B Common Stock may not be transferred until such
time as MGI has registered the Class A Common Stock and Class B Common Stock
under Section 12 of the Exchange Act, except in the case of "permitted
transfers". The term "permitted transfers" is defined as transfers or
assignments: (i) by VK/AC to its common stockholders in the Spin-Off; (ii) to
MGI or its affiliates; (iii) to existing stockholders of MGI who were
stockholders of VK/AC and received Class A Common Stock and Class B Common Stock
in the Spin-Off; (iv) by bequest or the laws of descent or distribution; (v) in
connection with a transfer to an unaffiliated third party pursuant to a merger,
consolidation, stock for stock exchange, tender offer or similar transaction
involving MGI; (vi) to a trust for employees of MGI and its subsidiaries
established under a qualified employee benefit plan; (vii) by a trust to the
trust's beneficiaries; (viii) for cash only in transactions which would be
exempt from the


                                      122
<PAGE>   125
registration requirements of Section 5 of the Securities Act, by virtue of the
exemption provided by Section 4(2) of the Securities Act if the transferor were
the issuer of the shares, provided that the transferee is an "accredited
investor" within the meaning of Rule 501(a) under the Securities Act and
subject, in certain cases, to compliance with a right of first offer in favor of
MGI and C&D Fund IV, and to certain "take-along" rights of C&D Fund IV; or (ix)
pursuant to an effective registration statement under the Securities Act
simultaneously with a registration of the Class A Common Stock and Class B
Common Stock under Section 12 of the Exchange Act. Transfers under clauses (ii)
(other than to MGI), (iii), (iv), (v), (vi), (vii) and (viii) are subject to the
transferee agreeing to be bound by the same restrictions on transfer, provided
that transferees under clause (v) shall not be required to agree that in order
for any subsequent transfer by them to qualify as a "permitted transfer" of the
type contemplated by clause (viii) such transfer must be for cash or to agree
that such transfers would be subject to compliance with the rights of first
offer and "take along" rights referred to in clause (viii).

         Rights of First Offer.

         Under the MGI Certificate of Incorporation, the Class A Common Stock
and Class B Common Stock are subject to certain rights of first offer in favor
of MGI and C&D Fund IV. If a holder of Class A Common Stock or Class B Common
Stock desires to offer or to sell shares of Class A Common Stock or Class B
Common Stock owned by such holder in a transaction permitted under clause (viii)
of the definition of "permitted transfers", such holder must first make an offer
to sell such shares to MGI and C&D Fund IV at a price specified by such holder
in a notice to MGI and C&D Fund IV. MGI and C&D Fund IV, respectively, have the
right during successive 30-day periods following receipt of such notice to
purchase all (but not less than all) of such shares at the price and on the
terms offered. If MGI and C&D Fund IV elect not to exercise such rights, the
holder may sell shares to a third party at no less than 90% of the price and on
the terms initially offered to MGI and C&D Fund IV. The rights of first offer in
favor of MGI and C&D Fund IV terminate upon the registration of the Class A
Common Stock and Class B Common Stock under Section 12 of the Exchange Act.

         Take-Along Rights.

         Under the MGI Certificate of Incorporation, the Class A Common Stock
and Class B Common Stock is subject to certain "take-along" rights of C&D Fund
IV. In the event that C&D Fund IV elects to sell all of its shares of Class A
Common Stock and Class B Common Stock to a third party, each holder of Class A
Common Stock and Class B Common Stock has an obligation to sell its shares to
such third party on the same terms and at the same price as C&D Fund IV. The
"take-along" rights of C&D Fund IV terminate upon the registration of the Class
A Common Stock and Class B Common Stock under Section 12 of the Exchange Act.

         Registration and Participation Rights.

         All holders of outstanding shares of MGI Common Stock are entitled to
the benefits of and bound by the obligations set forth in the Registration and
Participation Agreement dated as of August 31, 1996 among MGI and each of the
holders of MGI Common Stock (the "Existing Registration and Participation
Agreement"). Pursuant to the Existing Registration and Participation Agreement,
the holder or holders of certain percentages of the MGI Common Stock at the time
outstanding, that is registrable thereunder, have the right to initiate one or
more of all or part of such holder's or holders' registrable MGI Common Stock.
Since the initial request must be made by the holder or holders of 50% of the
outstanding shares, C&D Fund IV effectively control the initial registration of
the MGI Common Stock. Subsequent requests may be made by the holders of 10% of
the outstanding shares, provided that the holders of at least 20% of the
outstanding shares participate in the registration. The Existing Registration
and Participation Agreement requires MGI to pay the expenses of three such
registrations. In addition, holders of MGI Common Stock have rights to
participate in certain registered public offerings initiated by MGI, for which
the registration expenses will also be borne by MGI.

                                      123
<PAGE>   126
         Under the Existing Registration and Participation Agreement any such
stockholders who are "accredited investors," as such term is defined in Rule 501
of Regulation D under the Securities Act, also have the right to purchase
proportionately additional shares of capital stock proposed to be issued by MGI
to C&D Fund IV or its affiliates.

         Additionally, under the Existing Registration and Participation
Agreement (and under the MGI Certificate of Incorporation), the Class A Common
Stock and Class B Common Stock will be subject to a holdback provision under
which such shares may not be transferred in any public sale or distribution,
including sales pursuant to Rule 144 and Rule 144A under the Securities Act,
during the 20-day period prior to and the 180-day period after the effective
date of any registration statement for a public offering filed in respect of
MGI's equity securities (other than as part of such public offering).

MGI CLASS C COMMON STOCK

         Pursuant to the terms of the existing management stock subscription
agreements between MGI and each of the holders of the outstanding shares of
Class C Common Stock, such holder's right to sell or otherwise transfer or
pledge the outstanding shares of Class C Common Stock is limited as described
below and, generally, such outstanding shares of Class C Common Stock may be
transferred only to the estate of such holder or his or her beneficiary under
the holder's will upon the death of the holder. Upon issuance of shares of
Class C Common Stock to the holders of the MGI Employee Options upon their
exercise (the "Exercise Shares") such Exercise Shares will be subject to
substantially the same contractual restrictions on transferability as the
outstanding shares of Class C Common Stock. These contractual transfer
restrictions terminate automatically upon the occurrence of an initial public
offering of the Class A Common Stock and/or Class B Common Stock led by one or
more underwriters, at least one of which is of nationally recognized standing
(a "Public Offering"). In addition, pursuant to the management stock option
agreements, holders of the MGI Employee Options are not be permitted to sell or
otherwise transfer the Employee Options at any time, other than pursuant to the
laws of descent and distribution upon the death of the holder. The restrictions
on transferability applicable to the Exercise Shares under the MGI management
stock subscription agreements, discussed above, will continue to apply to the
Units exchanged for the Class C Common Stock and to the Units that will be
issuable upon the exercise of the MGI Employee Options.

         Right of First Refusal.

         The outstanding shares of Class C Common Stock and the Exercise Shares
are subject to substantial restrictions on transferability, including a right of
first refusal of MGI and C&D Fund IV, which make it virtually impossible for
such outstanding shares of Class C Common Stock or Exercise Shares to be
transferred without the consent of MGI and C&D Fund IV. Each certificate
representing outstanding shares of Class C Common Stock or Exercise Shares bears
a legend indicating that the transferability of such outstanding shares of Class
C Common Stock and Exercise Shares is restricted by the applicable management
stock subscription agreement.

         Repurchase Rights.

         In the event that the employment of the holder of outstanding shares of
Class C Common Stock or of MGI Employee Options with MGI terminates for any
reason whatsoever, MGI and C&D Fund IV have successive rights (but not the
obligation) to repurchase all or a portion of the outstanding shares of Class C
Common Stock, exercisable MGI Employee Options and Exercise Shares then held by
the holder. In addition, such holder has the right to require MGI to repurchase
such holder's outstanding shares of Class C Common Stock and Exercise Shares
(but not MGI Employee Options) if such holder's employment (x) is terminated by
MGI other than for "Cause" (as defined in the applicable management stock
subscription agreements) or, in the case of a holder who, as of the effective
date of such termination, is a party to an effective employment agreement with
MGI, for "good reason" (as defined in such employment agreement) or (y)
terminates by reason of his death, permanent disability (as defined in the
applicable management stock subscription agreements) or retirement at or after
age 60 (any such termination described under clause (x) or (y), a "Special
Termination").

         The repurchase price will, in general, be equal to the fair market
value of the outstanding shares of Class C Common Stock or Exercise Shares, as
determined by the Board of Directors of MGI (the "Board") in accordance with
the terms of the applicable management stock subscription agreements as of the
date (the "Determination Date") of the holder's termination of employment,
reduced int he case of the MGI Employee Options by the option exercise price,
and could be higher or lower than the cost of such outstanding shares of Class
C Common Stock or Exercise Shares to the holder. Payment of the repurchase
price for the outstanding shares of Class C Common Stock, Exercise Shares and
exercisable MGI Employee

                                      124
<PAGE>   127
Options will generally be made at the closing of such repurchase shortly
following receipt by the holder of the notice of election to repurchase from
MGI and/or C&D Fund IV, as the case may be, or, solely in the case of a
repurchase of outstanding shares of Class C Common Stock and/or Exercise Shares
following a Special Termination, receipt by MGI of the holder's notice
requiring MGI to repurchase such outstanding shares of Class C Common Stock
and/or Exercise Shares. However, if the Determination Date occurs during the
first or fourth fiscal quarter of any fiscal year of MGI, payment of a portion
of the repurchase price may be deferred until receipt by MGI of an annual
valuation of the outstanding shares of Class C Common Stock as of the last day
of the fiscal year of MGI ending immediately prior to such first fiscal quarter
or coincident with the end of such fourth fiscal quarter. Notwithstanding the
foregoing, if the holder's employment is terminated for Cause, all MGI Employee
Options will be forfeited and the purchase price for the outstanding shares of
Class C Common Stock and Exercise Shares will be the lesser of the initial
purchase price for such outstanding shares of Class C Common Stock or Exercise
Shares, as applicable, and the fair market value of such outstanding shares of
Class C Common Stock or Exercise Shares as of the date of termination.

         The closing of any such repurchase by MGI from a holder of such
outstanding shares of Class C Common Stock, exercisable MGI Employee Options or
Exercise Shares will be deferred, if such repurchase would result in a
violation of, or default under, any of MGI's financing agreements, would
violate the MGI Certificate of Incorporation or would be prohibited by
applicable law. In the event such a deferral is required, the repurchase price
for the outstanding shares of Class C Common Stock, exercisable MGI Employee
Options or Exercise Shares, as applicable, is generally determined as of the
Determination Date for such repurchase and, except as described below, will
include interest for the period from such Determination Date until the deferred
closing of such repurchase. Solely in the case of a deferred repurchase of
outstanding shares of Class C Common Stock or Exercise Shares pursuant to a
holder's election to require MGI to repurchase such outstanding shares of Class
C Common Stock or Exercise Shares following a Special Termination, the
repurchase price for the outstanding shares of Class C Common Stock or Exercise
Shares is determined as of the deferred closing date that such repurchase
actually takes place and will not include interest.

         Upon the termination of a holder of such outstanding shares of
Class C Common Stock's employment for any reason and the expiration of the
period during which MGI and C&D Fund IV may elect to repurchase such holder's
outstanding shares of Class C Common Stock and, in the case of a Special
Termination, the period during which such holder may require MGI to repurchase
such outstanding shares of Class C Common Stock, the outstanding principal and
interest balance on any loan provided to such holder by MGI to finance the
purchase of the outstanding shares of Class C Common Stock will become due in
full. Pursuant to the applicable management stock subscription agreement and
the promissory note evidencing such loan, each holder is required to apply the
repurchase price, if any, received from MGI and/or C&D Fund IV to the
prepayment of such outstanding principal and interest balance. Such mandatory
prepayment is for an amount equal to the entire principal balance and accrued
interest then outstanding under such loan. Except in the case of a Special
Termination as described above, such holder does not have the right to require
MGI or C&D Fund IV to repurchase any outstanding shares of Class C Common
Stock, MGI Employee Options or Exercise Shares in the event MGI and C&D Fund IV
do not exercise their respective repurchase rights. As a result, if MGI and C&D
Fund IV do not exercise their repurchase rights, a holder who has chosen to
finance the purchase of the outstanding shares of Class C Common Stock in part
under the loan program may be required to obtain funds from an alternative
source to prepay such loan in the event of his termination of employment.

         Registration and Participation Rights.

         All holders of outstanding shares of Class C Common Stock are entitled
to the benefits of and bound by the obligations set forth in the Existing
Registration and Participation Agreement. See "--MGI Class A and Class B Common
Stock--Registration and Participation Rights" above.

         Pursuant to the applicable management stock subscription agreements,
each holder of such outstanding shares of Class C Common Stock has agreed that
if MGI files a registration statement under the Securities Act with respect to
an underwritten public offering of any shares of its capital stock, the holder
will not effect any public resale or distribution of any shares of MGI Common
Stock (other than as part of such underwritten public offering), including, but
not limited to, pursuant to

                                      125
<PAGE>   128
Rule 144 or Rule 144A under the Securities Act, during the 20 days prior to and
180 days after the effective date of such registration statement. This holdback
restriction impairs such holder's ability to sell his outstanding shares of
Class C Common Stock and Exercise Shares in the public market if MGI becomes a
public company.

RIGHTS AND OBLIGATIONS OF THE UNIT HOLDERS

         Pursuant to the Merger, MGI Common Stock will be converted into Units. 
As noted above, the rights and obligations of Unit holders will be governed by 
the Delaware Act, the Parent's Certificate of Formation and the LLC Agreement. 
Therefore, in contrast to the rights and obligations of MGI stockholders
described above, Unit holders will have the following rights.

MANAGEMENT OF THE PARENT UNDER THE LLC AGREEMENT

         Board of Directors.

         Generally, the business of the Parent will be managed by or under the
direction of a committee of the Parent (the "Board" or the "Board of
Directors"), each member of which (a "Director") will serve until a successor is
elected as provided in the LLC Agreement or until his earlier death, resignation
or removal. The LLC Agreement provides that the Board will consist of at least
three persons, and further requires all members ("Members") of the Parent, at
all times after the Closing Date and until the settlement date of the first
underwritten public offering of equity securities of the Parent or a successor
entity (the "IPO Date"), to vote their respective Units in such manner as may be
necessary to ensure that (A) the Board at all times consists of (i) two of the
Founding Stockholders nominated by the Founding Stockholders, (ii) the chief
executive officer of MCM ("MCM Nominee"), (iii) the chief executive officer (if
any) of the Parent ("CEO Nominee"), (iv) three nominees of C&D Fund IV who are
employees of CD&R, Brera or other affiliates of C&D Fund IV (the "C&D Fund IV
Nominees"), and (v) up to six additional persons not affiliated with CD&R, C&D
Fund IV, Brera or any of the Founding Stockholders, who are nominated by C&D
Fund IV with the consent of Mr. Yergin, or in the event of Mr. Yergin's death,
legal incapacity or termination of employment for cause or disability, Mr.
Rosenfield or Mr. Stanislaw (the "Consenting CERA Principal"), which consent
will not be unreasonably withheld, and (B) all such persons are elected to serve
as Directors. Until the IPO Date, Directors may not be removed without cause
without the consent of the Member or Members that nominated such Director, and
the Member or Members who nominated or appointed any Director whose position has
become vacant due to such Director's resignation, removal or inability to serve
for any reason will be entitled to appoint a replacement Director to fill such
vacancy. A majority of the Members (by number of Units held) or of the Directors
may remove a Director for cause. For the identity of the initial directors, see
"Management," above.

         An election of Directors will be held, and new Directors will be
elected (or existing Directors will be reelected), at each annual meeting of
Members, which will be held on the third Tuesday of October of each year
(starting in 1998) or at such other time as the Board of Directors shall
determine. At each election of Directors, each Member will be entitled to one
vote per Unit held of record (other than non-voting Units), and the presence, in
person or by proxy, of the holders of a majority of the Units entitled to vote
will constitute a quorum. Since, as described above, the LLC Agreement requires
all Members to vote their respective Units, at all times prior to the IPO Date,
for the election to the Board of Directors of persons nominated as described in
the preceding paragraph, election of such nominees at all times prior to the IPO
Date is assured absent amendment of the LLC Agreement.


                                      126
<PAGE>   129
         Until the earlier of (a) the IPO Date and (b) the issuance of the CERA
Contingent Units, the Goldman Contingent Units and the CERA Employee Contingent
Units (collectively, the "Contingent Units"), any (i) acquisition or disposition
of a business or assets having a value in excess of $15,000,000, (ii) a capital
expenditure involving more than $15,000,000, (iii) issuance of Units (or
securities convertible into or exchangeable for Units, or options, warrants or
other rights to acquire Units or such securities) for aggregate consideration in
excess of $15,000,000, other than the Contingent Units, the Contingent Options,
Existing MGI Options, the options granted under the CERA Option Plan or the MGI
Option Plan, and the Units issuable upon exercise thereof, (iv) entry into new
lines of business, (v) dissolution, (vi) public offering of equity securities of
the Parent or a successor entity, and (vi) with certain exceptions, incurrence
of indebtedness or guarantees in respect thereof in excess of $15,000,000, will
require approval of at least 75% of the Directors then in office. In addition,
until the earlier of (a) the IPO Date and (b) the issuance of the Contingent
Units, the sale of 50% or more of CERA or the spin-off to Members of all of
CERA's capital stock will require the approval of the Consenting CERA Principal.

         The LLC Agreement requires that until the IPO Date, the Board of
Directors of CERA and of MGI shall be composed of the same individuals as the
Board of Directors of the Parent.

         Executive Committee.

         The LLC Agreement provides for the establishment of a committee of the
Board of Directors to be designated as the Executive Committee and to be
composed of the Chairman, the Consenting CERA Principal, the CEO Nominee (if
any), the MCM Nominee and such other Directors as may be designated by the
Board. During the intervals between meetings of the Board, the Executive
Committee will have all the powers and authority of the Board in the management
of the Parent, except that the Executive Committee will not have the authority
to take any action requiring (i) a vote greater than a majority of Directors
present as described above or (ii) the consent or approval of the Consenting
CERA Principal or any one or more of the C&D Fund IV Nominees, or authorizing
any distribution by the Parent to the Members.

         Officers.

         The Board of Directors may select certain individuals to be designated
as officers ("Officers") of the Parent, with such titles as the Board may
determine. The Board may appoint a Chief Executive Officer, a President, a Chief
Financial Officer, a Secretary and a Treasurer, and one or more Vice Presidents,
Assistant Secretaries and Assistant Treasurers, provided that until the IPO
Date, the Chief Executive Officer will be appointed by the C&D Fund IV Nominees
with the consent of the Consenting CERA Principal, whose consent will not be
unreasonably withheld. Each Officer will have certain authority by virtue of
being appointed an Officer and may be further authorized from time to time by
the Board of Directors to take any action that the Board of Directors delegates
to such Officer.

         Rights to Distributions and Allocations.

         The LLC Agreement authorizes the issuance of Units for such
consideration and on such terms and conditions as shall be established by the
Board of Directors in its sole discretion without approval of the Members.
Members (i) will be entitled to receive, to the extent of available cash and
cash equivalent assets of the Parent, cash distributions in amounts intended to
enable Members and certain other persons or entities to discharge their United
States federal, state and local income tax liabilities arising from certain
allocations made with respect to the Units as described below, (ii) other than
with respect to certain distributions relating to specified disposition
transactions (as described below), will be entitled on a pro rata basis to such
distributions, if any, prior to the dissolution and liquidation of the Parent as
may be determined by the Board of Directors of the Parent in its sole
discretion, (iii) will be allocated income, gains, losses, credits and
deductions of the Parent in accordance with the respective Units owned by the
Members, subject to certain variations for income tax purposes called for by
applicable provisions of the Code and regulations promulgated thereunder, and
(iv) will be entitled on a pro rata basis, upon dissolution and liquidation of
the Parent, to all remaining assets after satisfaction of the Parent's
liabilities to creditors.

         With respect to distributions to Members (i) of any capital stock of
MGI or less than all of the capital stock of CERA prior to the earlier of the
issuance of the Contingent Units and June 30, 2000, or (ii) of the net proceeds
of any sale or other disposition (other than in a distribution to Members of
capital stock of MGI or CERA), prior to the earlier of the issuance of the
Contingent Units and June 30, 2000, of capital stock of MGI, more than 50% of
the assets of MGI, or capital stock or assets or CERA in a transaction that does
not constitute a Termination Event, Members will be entitled to receive each
such distribution on a pro rata basis, except that each Member who, at the time
of determination, has a right to receive Contingent Units will be treated,
solely for the purposes of such distribution, as if such Member owned the number
of Contingent Units that would have been issuable to such Member if the closing
of a Termination Event (other than an underwritten public offering) that did not
constitute a Qualifying Sale had occurred at such time of determination.

         Voting and Certain Other Rights.

         Except with respect to non-voting Units (the "Non-Voting Units"), which
will be issuable by the Parent only in limited circumstances and only to those
holders of Units subject to certain legal or regulatory constraints on their
ability to possess voting power with respect to any single entity in excess of
certain thresholds, and except with respect to certain rights and obligations
applicable, pursuant to the LLC Agreement, to certain holders of Units with
respect to (i) nomination, election and/or appointment of members of the Board
of Directors, (ii) rights and obligations relating to transferability of Units
and rights to request registration of Units under the applicable securities
laws, (iii) Contingent Units, and (iv) certain other matters, each Unit will be
identical in all respects to each other Unit. Units other than Non-Voting Units
("Voting Units") will be the only class of equity interests in the Parent
outstanding immediately following the closing of the Merger and the Exchange.

         Holders of record of Voting Units will be entitled to notice of, and to
vote at, meetings of the Members and to act with respect to matters as to which
approval of the Members may be solicited. There will be an annual meeting of the
Members starting in 1998, and special meetings of the Members may be called by
the Board, the Chairman or the Vice Chairman of the Board, the Parent's chief
executive officer, or upon written request of Members holding not less than 20%
of the outstanding Units. Holders of Voting Units will be entitled to one vote
per Voting Unit on matters submitted to a vote or consent of holders of Units.
The LLC Agreement provides that the vote of a majority of Voting Units
represented at a meeting of Members at which a quorum is present will be
sufficient for the transaction of business at such meeting, except that, upon
the recommendation of the Board of Directors that the Members give such
approval, the approval of at least two-thirds of the Members (by number of
Units) then entitled to vote at a meeting of Members will be required for (i)
with certain limited exceptions, any merger, consolidation, conversion or
reorganization of the Parent, (ii) dissolution of the Parent and (iii) the sale
 other disposition of all or substantially all of the assets of the Parent or
the sale or other disposition of all of the capital stock of MGI or CERA owned
by the Parent, other than in a spin-off of all of the capital stock of MGI or
CERA. Pursuant to the LLC Agreement, as described above, prior to the IPO Date,
the Members will be required to vote all of their respective Units for the
election as directors of the nominees described under "The Limited Liability
Company Agreement--Management--Board of Directors" above.

         Appraisal Rights.

         Pursuant to the terms of the LLC Agreement, holders of Units will not
be entitled to any appraisal or dissenters' rights.

<PAGE>   131
         Bailment Agreement.

         Pursuant to the LLC Agreement, all of the Unit Certificates will be
held by the Parent, as the Unit Bailee under the Unit Bailment Agreement. The
Unit Bailee will hold the Unit Certificates for safekeeping in a safe deposit
box at a financial institution chosen by the Unit Bailee, and each Member will
receive a receipt from the Unit Bailee for the applicable Unit Certificate and a
photocopy of such Certificate. During the time the Unit Bailee has possession of
the Unit Certificates of each Member, each such Member will retain all rights of
ownership of the Units represented by such Unit Certificates, including but not
limited to the right to receive and retain distributions, to vote such Units, to
transfer title to such Units (subject to the terms of the LLC Agreement and any
other applicable agreements) and to execute consents, waivers or releases and
otherwise to act in respect of such Units in all matters acted upon by the
Members. Pursuant to the Unit Bailment Agreement, the Unit Bailee will have no
security or ownership interest in the Unit Certificates and each Member will be
entitled to regain possession of such Member's Unit Certificates at any time
upon five days' prior notice and upon compliance with certain other
requirements.

RESALES OF UNITS

         Restrictions on Transfer.

         The LLC Agreement will provide that, during the period ending on the
earlier of three years after the Closing Date and one year after the IPO Date,
each Member who, together with certain related trusts, if any, owned, as of the
Closing Date, 5% or more of the then outstanding Units (each such Member, a
"Restricted Holder"), each such trust and each of such Restricted Holder's and
such trust's Permitted Transferees (as defined below) may transfer Units only
(i) to an unaffiliated third party (A) in a sale of all of the Units pursuant to
an exercise of the take-along rights described in "--Take-Along Rights" below or
(B) pursuant to a merger, conversion, consolidation or reorganization of the
Parent, other than in a transaction described in the following clause (ii), (ii)
pursuant to certain transactions where the organizational form of the Parent is
changed (for example, from a limited liability company to a corporation) but the
owners and proportional ownership of voting securities or other equity interests
before and after such change generally are unchanged, (iii) in a public offering
of Units pursuant to an effective registration statement under the Securities
Act, (iv) to a Permitted Transferee or (v) to the Parent or any subsidiary of
the Parent.

         In addition, prior to the IPO Date, each Member other than a Member
subject to the transfer restrictions described in the immediately preceding
paragraph, and, after the expiration of the period described in the immediately
preceding paragraph, each Member, may transfer such Member's Units only (i) in
any of the transactions described in clause (i) through (v) of the immediately
preceding paragraph, (ii) to a Member who was a Member as of the Closing Date or
(iii) subject to compliance with the participation rights, rights of first offer
and take-along rights described in "--Participation Rights," "--Rights of First
Offer" and "--Take-Along Rights" below, to Restricted Holders or third parties
who are "accredited investors," for cash in transactions that are exempt from
the registration requirements of the Securities Act pursuant to Section 4(2)
thereof. After the IPO Date, in addition to transfers in any of the transactions
described in the immediately preceding sentence, each such Member will also be
entitled to transfer such Member's Units to any third party, subject to
compliance with such participation rights and with Rule 144 or Rule 145 under
the Securities Act, if applicable.



                                      129
<PAGE>   132

         A "Permitted Transferee" will be defined in the LLC Agreement to mean
(i) any transferee by bequest or the laws of descent or distribution, (ii) any
trust for employees of the Parent and/or any of the Parent's subsidiaries
established under a qualified employee benefit plan, (iii) in the case of any
Member that is a trust, the trust beneficiaries of such trust, (iv) as to any
Member that is a corporation, company, partnership or other entity, certain
affiliates of such Member and (v) in the case of any Member that is an
individual, any trust the only actual beneficiaries under which are such
individual and/or one or more of his brothers and sisters (whether by whole or
half blood), spouse, ancestors and lineal descendants, provided, in each case,
that the Permitted Transferee agrees in writing to be bound by the terms of the
LLC Agreement and complies with certain additional requirements.

         Further, (i) any transferee of Units will, unless such requirements are
waived by the Board of Directors of the Parent, be admitted as a substitute
Member only upon (a) execution by the transferee and the transferor of such
instruments as the Board of Directors or any officer of the Parent deems
reasonably necessary or desirable to effect the substitution, (b) the agreement
in writing by the transferee to be bound by the LLC Agreement, and (c) the
agreement in writing by the transferee to provide the Parent with such
information (including the transferee's employer identification number or social
security number, as applicable, and the amount paid for the Units) as the Parent
may request from time to time, (ii) it is a condition to any transfer of Units
that (x) the Board of Directors of the Parent determine that the proposed
transfer will not cause the Parent to violate applicable law or the terms of any
then outstanding indebtedness of the Parent, guarantees of indebtedness or
related documents, result in the Parent becoming subject to certain securities,
employee benefits, investment company and other specified legal requirements, or
otherwise constitute a Prohibited Transaction (as defined in the LLC Agreement),
and (y) in the case of a transfer to a Permitted Transferee (or in a transaction
described in clause (ii) or (iii) of the first sentence of the second preceding
paragraph), the transferor deliver to the Parent (A) an opinion of counsel
reasonably satisfactory to the Parent relating to certain matters specified in
the LLC Agreement, and (B) a certificate concerning compliance with the
restrictions on transfer set forth in the LLC Agreement and certain related
matters, and certain other documentation, (iii) each person or entity obtaining
Units, other than the persons and entities admitted as Members pursuant to the
Merger, the Exchange or the transfer of Units and Contingent Units pursuant to
the CERA Unit Grant Plan or exercising options to purchase Units (provided that
each such person or entity who exercised such options executes a subscription
agreement and tenders full payment of the exercise price of such options), will
be admitted as an additional Member at the time such person or entity (A)
executes a counterpart of the LLC Agreement, (B) complies with the applicable
resolution, if any, of the Board of Directors of the Parent with respect to such
admission, and (C) is named as a Member in the Parent's membership register, and
(iv) transfers of Units prior to the IPO Date are subject to certain further
restrictions, which attempt to prevent the Parent's being treated as a publicly
traded partnership for tax purposes. See "The Limited Liability Company 
Agreement--Resales of Units--Restrictions on Transfer" for a description of such
further restrictions; see "The Merger and the Exchange--Federal Income Tax
Considerations" for a discussion of the tax consequences of the Parent's being
treated as a "publicly traded partnership."

         Holdback Agreement.

         Under the LLC Agreement, the Units will be subject to a holdback
provision under which such Units may not be transferred in any public sale or
distribution, including sales pursuant to Rule 144 or Rule 144A under the
Securities Act, during the 20-day period prior to and the one-year period after
the effective date of any registration statement for a public offering filed in
respect of any equity securities of the Parent (other than as part of such
public offering).



                                      130
<PAGE>   133

         Participation Rights.

         Each Member will be entitled, prior to such time as 30% of the then
outstanding Units have been sold to the public pursuant to an effective
registration statement under the Securities Act or pursuant to Rule 144 under
the Securities Act (the "Establishment of a Public Market"), to participate
proportionately in certain "qualifying sales" of Units by a Restricted Holder,
certain related trusts, if any, and/or any of their Permitted Transferees.
Subject to certain qualifications, "qualifying sales" generally will be any
sales by a Restricted Holder, such trusts and/or such Permitted Transferees to a
third party in transactions not involving a distribution and/or sale to the
public (whether pursuant to a public offering registered under the Securities
Act, Rule 144, brokers' transactions or otherwise, but not pursuant to Rule 144A
or any successor provision) after such Restricted Holder, trusts and/or
Permitted Transferees have sold an aggregate of 5% of the Units held by such
Restricted Holder, trusts and/or Permitted Transferees.

         Rights of First Offer.

         Under the LLC Agreement, prior to the IPO Date, the Units will be
subject to certain rights of first offer in favor of the Parent (whose right may
be assigned to MGI or CERA) and each Restricted Holder. If a holder of Units
desires, prior to the IPO Date, to offer or to sell Units owned by such holder
in a transaction described in clause (iii) of the first sentence of the second
paragraph of "--Restrictions on Transfer" above, such holder must first make an
offer to sell such Units to the Parent and, if the Parent does not accept such
offer within a twenty-day period, to each Restricted Holder at a price and on
the other terms specified by such holder of Units in a notice to the Parent.
Each Restricted Holder shall have the right during the two successive twenty-day
periods following the expiration of the first twenty-day period to purchase such
Restricted Holder's pro rata portion of the number of such Units that the Parent
(or, with respect to the second such twenty-day period, the other Restricted
Holders) shall not have elected to purchase, which right may be exercised
subject to such Restricted Holder securing financing for such purchase. If the
Parent and the Restricted Holders do not elect to exercise such rights with
respect to all the Units so being offered, the holder may sell such Units to a
third party at no less than 90% of the price and on the other terms initially
offered to the Parent and the Restricted Holders.

         Take-Along Rights.

         Under the LLC Agreement, prior to the IPO Date, the Units will be
subject to certain "take-along" rights of the holders of more than 50% of the
outstanding Units (the "Majority Holders"). In the event that the Majority
Holders elect to sell all of their Units to a third party, each other holder of
Units will, if requested to do so by the Majority Holders, have an obligation to
sell such holder's Units to such third party on the same terms and at the same
price as the Majority Holders.

         Registration Rights.

         Under the LLC Agreement and subject to the limitations described
therein, the Parent will agree to grant to (i) the holder or holders (other than
the Founding Stockholders and certain related trusts) of 30% of the Registrable
Securities (as such term is defined in the LLC Agreement and which will
generally include all of the Units to be issued in connection with the
transactions contemplated by the Merger Agreement) with respect to the initial
request and 10% of the Registrable Securities with respect to any subsequent
requests, and (ii) with respect to two requests only after the third anniversary
of the Closing Date, the Founding Stockholders holding a specified percentage of
Units, the right to require the Parent to register for resale (subject to
certain minimum registration requirements), under the Securities Act and
applicable state securities laws, Units that such holders or certain of their
affiliates propose to sell. Since the requests for registration under clause (i)
of the immediately preceding sentence exclude the Founding Stockholders and the
initial request thereunder must be made by the holders of at least 30% of the



                                      131
<PAGE>   134
Registrable Securities, C&D Fund IV will effectively control the initial
registration of the Units if such registration occurs pursuant to the exercise
of registration rights granted under the LLC Agreement prior to the third
anniversary of the Closing Date. The Parent will be obligated to pay all
expenses incidental to the first two registrations requested pursuant to clause
(i) of the first sentence of this paragraph and each of the two registrations
requested pursuant to clause (ii) of such first sentence, in each case,
excluding underwriting discounts and commissions. Subject to certain limitations
set forth in the LLC Agreement, all holders of Units as of the Closing Date will
be entitled to participate in any such registration for resale, or in any
registration of equity securities of the Parent otherwise undertaken by the
Parent.

ISSUANCE OF ADDITIONAL SECURITIES UNDER THE LLC AGREEMENT

         The LLC Agreement, subject to the requirements of the Delaware Act and
other applicable law, and subject to certain limitations set forth in the LLC
Agreement, grants the Board of Directors the authority to issue and sell
additional Units and other securities of the Parent, at any time and on such
terms and conditions as the Board may determine, and without the approval of the
holders of Units.

         If the Parent proposes to issue or sell, prior to the Establishment of
a Public Market, any additional Units to a Restricted Holder or any affiliate
thereof (subject to certain exceptions), the Parent will be required to offer to
each holder of Registrable Securities who is an "accredited investor," on the
same terms and conditions as will be applicable to the sale to such Restricted
Holder or such affiliate, the right to purchase the number of additional Units
such that such holder of Registrable Securities would have the opportunity to
hold the same percentage of Units, after giving effect to the sale to such
Restricted Holder or such affiliate, as such holder of Registrable Securities
held immediately prior to such sale.

AMENDMENT OF LLC AGREEMENT

         The LLC Agreement may not be amended except by a written agreement
signed by the Parent and a majority of the Members (by number of Voting Units),
except that (i) any amendment of any provision of the LLC Agreement requiring
the affirmative vote of more than a majority of the Directors then in office, or
the consent or approval of the Consenting CERA Principal or one or more of the
C&D Fund IV Nominees, will also require the corresponding vote of such
percentage of the Directors or the consent or approval of such other person or
entity, as the case may be, (ii) any amendment of any provision of the LLC
Agreement requiring the affirmative vote of a specified percentage or proportion
of the Members or holders of Units will require the affirmative vote of such
percentage or proportion of such Members or holders, (iii) any amendment or
modification of any provision of the LLC Agreement providing for, or resulting
in, the direct reduction or elimination of any right, preference or benefit
granted to any particular person or entity or group of persons or entities will
require the consent of such person or entity or group of persons or entities,
and (iv) any amendment of any other provision of the LLC Agreement (A) to
satisfy any requirements, conditions, guidelines or opinions contained in any
opinion, directive, order, ruling or regulation of the Commission, the IRS or
any other United States federal or state agency, or in any United States federal
or state statute, compliance with which the Board deems in good faith to be in
the best interests of the Parent and (B) to cure any ambiguity or mistake or
correct or supplement any provision of the LLC Agreement that may be incomplete
or inconsistent with any other provision contained therein, may be signed by the
Parent only, without any approval of the Members being required, if such
modification or amendment is authorized by the Board.

FIDUCIARY AND OTHER DUTIES UNDER THE LLC AGREEMENT

         The fiduciary obligations of officers, directors, members and
affiliates of limited liability companies is a developing area of the law. In an
effort to create more certainty regarding the duties of the officers and
directors of the Parent to the Parent and the Members, the LLC Agreement
specifies certain standards of behavior required of such persons, sets forth
procedures that may be used for resolution of conflicts of interest and
describes certain activities that will not be deemed to violate fiduciary or
other duties.

         The LLC Agreement provides that, except as otherwise specifically
provided therein, the duties and obligations of Officers, Directors and Members
to the Parent will be the same as the duties owed by officers, directors and
stockholders, respectively, of a corporation organized under the DGCL to such
corporation. The Parent believes that there is more certainty under the DGCL
regarding duties owed by such persons than under the Delaware Act, primarily
because there are many judicial decisions under the DGCL and comparable
corporate statutes. Other provisions of the LLC Agreement contain language that
limits the liability of Officers, Directors, Members, their respective
affiliates and certain other persons (collectively, "Covered Persons") to the
Parent or the holders of Units. Such provisions are intended to permit Covered
Persons to act in good faith reliance on the provisions of the LLC Agreement;
with certain limitations, to allow certain Covered Persons to engage in outside
businesses and activities (including those competitive with the business of the
Parent) and to take for their respective own accounts investment opportunities
without first presenting such investment opportunities to the Parent; and to
permit the Officers and Directors to perform their duties to the Parent, without
undue uncertainty regarding the standards by which they will be judged or undue
risk of liability. The Parent believes that such provisions are necessary to
provide certainty and fairness with respect to the relationships between Covered
Persons and the Parent, some of which may potentially involve conflicts of
interest. See "The Merger and the Exchange--Interest of Certain Persons in the
Merger and the Exchange; Conflicts of Interest." The LLC Agreement provides,
among other things, that a Covered Person will not be liable for any act or
omission if such person acted in the good faith belief that such action was in,
or was not opposed to, the best interests of the Parent and in a manner believed
to be within the scope of authority conferred on such Covered Person by or
pursuant to the LLC Agreement.

                             AS OF SEPTEMBER 30, 1997




1.       Formation of Global Decisions Group LLC:

         On June 30, 1997, Global Decisions Group LLC (the "Company"), was
formed as a Delaware Limited Liability Company for the purpose of effectuating
the transaction described below.

         The members of the Company are MCM Group, Inc. ("MGI") and McCarthy
Crisanti & Maffei, Inc., ("MCM").

2.       Merger:

         On July 2, 1997, GDG Merger Corporation ("Merger Corp."), a Delaware
corporation, was incorporated as a wholly owned subsidiary of the Company.

         On August 1, 1997, the Company entered into an agreement and, as a
result, Merger Corp. will merge with MGI. The outstanding common stock of MGI
will be converted into units of the Company. As part of the agreement, the
stockholders of Cambridge Energy Research Associates, Inc. ("CERA") and the
limited partners of Cambridge Energy Research Associates Limited Partnership
("CERA LP") also agreed to exchange their outstanding stock of CERA and its
limited partnership interest in CERA LP, respectively, for units of capital of
the Company. MGI and CERA will be wholly owned subsidiaries of the Company
following the merger and exchanges. As a result of the completion of the merger
and the exchanges, each outstanding option to purchase common stock of MGI
under MGI's existing stock option plans will automatically be converted, based
on the exchange ratio, into equivalent options to purchase units in the Company.

         Closing of the transaction is anticipated by the end of January 1998.

MCM GROUP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years ended December 31, 1996, 1995 and 1994


1.       ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

         BASIS OF PRESENTATION
         MCM Group, Inc. ("MGI"), a Delaware corporation, was incorporated on
         August 21, 1996 as a wholly owned subsidiary of VK/AC Holding, Inc.
         ("Holding"). On that date, Holding was a majority owned subsidiary of
         The Clayton & Dubilier Private Equity Fund IV Limited Partnership ("C&D
         Fund IV"), which is managed by Clayton Dubilier & Rice, Inc. Prior to
         August 31, 1996, McCarthy, Crisanti & Maffei, Inc. ("MCM") was a wholly
         owned subsidiary of Holding. On August 31, 1996, Holding's ownership
         interest in MCM was transferred to MGI. On August 31, 1996, 100% of the
         outstanding Class A Common Stock of MGI was distributed to the
         stockholders of record of Holding as a dividend on their shares of
         Holding's common stock. Upon the distribution, MGI became a majority
         owned subsidiary of C&D Fund IV. The transfer of 100% of the MCM Common
         Stock to MGI has been accounted for in a manner similar to the
         pooling-of-interests method due to the common ownership of MGI and
         Holding by C&D Fund IV following the distribution. On October 31, 1996,
         C&D Fund IV sold its ownership interest in Holding, which then ceased
         to be an affiliate of MGI.

         These financial statements have been prepared in accordance with
         generally accepted accounting principles. The statements include the
         accounts of MGI and MCM and its subsidiaries McCarthy, Crisanti &
         Maffei, S.A. a 99.73% owned French subsidiary, and MCM Asia Pacific
         Company Limited an 85% owned subsidiary (collectively, "the Company").
         The 1995 financial statements and related amounts presented in the
         report represent those of MCM. All material intercompany accounts and
         transactions have been eliminated in consolidation. The preparation of
         financial statements in conformity with generally accepted accounting
         principles requires management to make estimates and assumptions that
         affect the reported amounts of assets and liabilities and disclosure of
         contingent assets and liabilities at the date of the consolidated
         financial statements and the reported amounts of revenues and expenses
         during the reporting period. Actual results could differ from those
         estimates.

         MCM and its subsidiaries are providers of specialized on-line financial
         information and analysis relating to domestic and international debt
         and currency markets. MCM distributes its products primarily through
         on-line telecommunications information networks to institutional
         clients in 57 countries. In addition to its headquarters in New York,
         MCM has offices in Boston, London, Paris, Tokyo, Hong Kong and
         Singapore.

         CASH AND CASH EQUIVALENTS
         The Company considers all highly liquid investments with maturities of
         three months or less to be cash equivalents.

         RESEARCH SERVICES
         Revenue from Research Services results from the Company producing and
         distributing electronic information services worldwide and is
         recognized when the services are provided. The life of the customers'
         contract period is generally one year. Amounts billed or collected
         relating to future periods are classified as unearned revenue and
         recognized as the services are provided.

         VENDOR COMMISSIONS
         Vendor commissions are royalties paid to distributors of the Company's
         on-line services.

<PAGE>   148
         RECEIVABLE FROM AFFILIATES
         Receivable from Affiliates represents amounts due from Holding's
         affiliates which arose from daily operations.

         DEPRECIATION
         The Company provides for depreciation of equipment using the straight
         line method over three years. Leasehold improvements and furniture are
         amortized over the lesser of the remaining lives of the leases or their
         estimated useful lives using the straight-line method. All fixed assets
         are stated at cost and related repair and maintenance charges are
         expensed as incurred. When assets are sold, retired or otherwise
         disposed of, the applicable costs and accumulated depreciation are
         removed from the accounts and the resulting gain or loss is included in
         the consolidated statement of income. Accumulated depreciation at
         December 31, 1996 and 1995 was approximately $1,027,000 and $745,000,
         respectively.

         AMORTIZATION
         The estimated life of Excess of Cost Over Fair Value of Net Assets
         Acquired was determined by an independent study. The Company assesses
         impairment of this asset based on several factors, including probable
         fair market value, cash flows, and the aggregate value of the business
         as a whole. Excess of Cost Over Fair Value of Net Assets Acquired is
         being amortized over twenty-five years on a straight line basis.
         Accumulated amortization of Excess of Cost Over Fair Value of Net
         Assets Acquired at December 31, 1996 and 1995 was approximately
         $3,015,000 and $2,235,000, respectively.

         TRANSLATION OF FOREIGN CURRENCIES
         The monetary assets and liabilities of foreign operations that are
         denominated in foreign currencies are translated into U.S. dollars at
         year end or historical exchange rates. Income and expense items are
         converted into U.S. dollars at average rates of exchange prevailing
         during the year. Foreign exchange gains and losses are not material to
         the consolidated financial statements.

         RECLASSIFICATIONS
         Certain 1995 and 1994 amounts have been reclassified to conform to the
         1996 presentation.

2.       INCOME TAXES:

         For periods prior to August 31, 1996, MCM joined with Holding in the
         filing of consolidated federal tax returns but filed separate local and
         state income and franchise tax returns. Pursuant to a tax sharing
         agreement, MCM paid federal income taxes to Holding as if MCM filed
         separate federal tax returns. For periods subsequent to August 31,
         1996, the Company will file its own consolidated federal and other tax
         returns.

         The Company accounts for income taxes in accordance with the provisions
         of Statement of Financial Accounting Standards (SFAS) No. 109,
         "Accounting for Income Taxes". Under this standard, deferred tax assets
         and liabilities are recognized for the estimated future tax
         consequences attributable to differences between the financial
         statement carrying amounts of existing assets and liabilities and their
         respective tax basis. Deferred tax assets and liabilities are measured
         using enacted tax rates in effect for the year in which those temporary
         differences are expected to be recovered or settled.

</TABLE>

         The deferred income tax liability shown on the consolidated balance
         sheets at December 31, 1996 and 1995 is due primarily to temporary
         differences between tax and book amortization of excess of cost over
         fair value of net assets acquired.

         The provision for income taxes is different from that which would be
         computed by applying the statutory federal income tax rate to income
         before taxes. The principal reasons for the differences are set forth
         in the table below.

3.       PROFIT SHARING:

         Prior to November 1, 1996, VKAC, an affiliated corporation of Holding,
         provided a defined contribution profit sharing plan (the "Plan")
         covering all eligible employees of MCM and was reimbursed by MCM for
         expenses under the Plan. VKAC contributed to a trust, that was
         qualified under the Internal Revenue Code, an amount which did not
         exceed the amount allowable as a deduction for federal income tax
         purposes. On November 1, 1996, MCM implemented its own defined
         contribution profit sharing plan as a continuation of and successor to
         the Plan. MCM's allocated portion of the contribution to the plans was
         approximately $273,000, $196,000 and $162,000, for the years ended
         December 31, 1996, 1995 and 1994, respectively.

4.       POSTRETIREMENT BENEFITS:

         Prior to August 31, 1996, Holding provided a postretirement health care
         plan for all eligible retired employees of MCM. The Company no longer
         provides such a plan for its employees.

5.       COMMITMENTS AND CONTINGENCIES:

         Rent expense for office space was approximately $1,387,000, $1,290,000
         and $1,122,000, net of sublease income of approximately $216,000,
         $227,000 and $133,000 from an affiliate of Holding, for the years ended
         December 31, 1996, 1995 and 1994, respectively. Future minimum lease
         commitments under non- cancelable long-term leases are as follows:

</TABLE>

         In the ordinary course of business, certain claims arise against the
         Company. Management believes such claims are without merit and will
         vigorously defend its position. In the opinion of management, based on
         the information currently available, the ultimate resolution of these
         claims will not have a material adverse affect on the Company's
         financial position or the results of its operations.

6.       FOREIGN OPERATIONS:

         The Company provides research services to various customers in foreign
         countries. For the years ended December 31, 1996, 1995 and 1994, such
         revenues amounted to approximately $17,388,000, $15,612,000 and
         $11,982,000, respectively.

7.       REDEEMABLE COMMON STOCK:

         The Company has sold 17,400 shares of its Class C Common Stock, par
         value $.01 per share, to members of management, other key employees and
         directors of the Company ("Management Investors"). The Company has
         agreed to repurchase 15,650 of these shares at fair market value under
         certain defined conditions, such as death, disability, retirement at
         normal retirement age, or termination of employment without cause. Fair
         market value will be periodically estimated by the Company's board of
         directors considering, among other factors, the value as determined by
         an independent appraisal. The shares of redeemable Class C Common Stock
         held by Management Investors have been presented as redeemable common
         stock and excluded from stockholders' equity.

         The shares of redeemable common stock are reported on the balance sheet
         at redemption value at issuance, which exceeds the estimated fair
         market value of the stock at December 31, 1996, less notes receivable
         of $765,000 from Class C stockholders. The remaining 1,750 shares ("non
         redeemable shares") are not required to be repurchased by the Company
         as described previously.

8.       STOCK OPTION PLANS:

         OPTIONS ISSUED UNDER THE STOCK OPTION PLAN
         Options to purchase 37,878 shares of Class C Common Stock were granted
         to the Management Investors pursuant to the MCM Group, Inc. Stock
         Option Plan (the "Stock Option Plan"). One half of the options issued
         under the Stock Option Plan were Service Options which will vest over a
         period of time up to five years, 20% on each anniversary of the option
         grant date subject to continued employment with the Company or a
         subsidiary and accelerated vesting in the event of death or a change in
         control of the Company. The Service Options expire on the tenth
         anniversary of the grant date. The other options issued under the Stock
         Option Plan were Performance Options which will vest three years from
         the date of grant subject to continued employment with the Company and
         the achievement of certain financial performance objectives by the
         Company and vesting in the event of death or change in control of the
         Company. All of the Performance Options become exercisable nine years
         from the grant date regardless of the achievement of the financial
         performance objectives.

         The following summarizes activity in the Stock Option Plan for the
         period ended December 31, 1996:

         At December 31, 1996, no options were exercisable and 11,122 shares
         were available for future grants.

         OPTIONS ISSUED UNDER THE SPECIAL STOCK OPTION PLAN:
         The Company's Special Stock Option Plan (the "Plan") provided for the
         grant of stock options on August 31, 1996 to certain current and former
         employees of Holding. The options were awarded in connection with the
         transfer of the ownership of MCM from Holding to the Company. As of
         December 31, 1996, options to purchase an aggregate of 48,110 shares of
         Class A Common Stock were outstanding under the Plan. The options are
         fully vested and are exercisable subsequent to the registration of the
         related Class A Common Stock.

         (a)    Average contractual life remaining in years.

         At December 31, 1996, no shares were available for future grants.

         With respect to both plans, the fair market value of the stock at the
         dates of grant of the stock options and at December 31, 1996, was less
         than the exercise price of the options, and, accordingly, there was no
         related compensation expense for the year ended December 31, 1996. In
         addition, there would not have been any compensation expense in
         accordance with SFAS No.
         123.

9.       DIVIDEND REQUIREMENT:

         Pursuant to a stock purchase agreement dated October 13, 1992, Van
         Kampen American Capital, Inc. ("VKAC"), a wholly owned subsidiary of
         Holding, purchased from Xerox Financial Services, Inc. all of the
         outstanding capital stock of The Van Kampen Merritt Companies, Inc. and
         its subsidiaries, including the Company. In connection with the
         acquisition, VKAC incurred substantial debt. Debt covenants required
         that the subsidiaries of VKAC pay dividends to VKAC equal to the
         subsidiaries' net income as long as the dividend did not put the
         subsidiary in noncompliance with any regulatory requirements. MCM paid
         such dividends to VKAC until December 20, 1994, at which time it was
         acquired by Holding and was no longer a subsidiary of VKAC.

10.      BANK LOANS

         A subsidiary maintains credit facilities in Japanese Yen which provide
         financing availability approximating $700,000, of which $657,000 was
         utilized as of December 31, 1996, with variable interest rates. The
         average interest rate during the year ended December 31, 1996 was
         1.875%. The Company is not required to pay any commitment fees.

MCM GROUP, INC., AND SUBSIDIARIES

Notes to Consolidated Condensed Financial Statements

(Unaudited)


1.   Organization and Basis of Presentation:

     MCM Group, Inc. ("MGI" or the "Company"), a Delaware corporation, was
     incorporated on August 21, 1996 as a wholly owned subsidiary of VK/AC
     Holding, Inc. ("Holding"). On that date, Holding was a majority owned
     subsidiary of The Clayton & Dubilier Private Equity Fund IV Limited
     Partnership ("C&D Fund IV"), which is managed by Clayton Dubilier & Rice,
     Inc. Prior to August 31, 1996, McCarthy, Crisanti & Maffei, Inc. ("MCM")
     was a wholly owned subsidiary of Holding. On August 31, 1996, 100% of the
     outstanding Class A Common Stock of MGI was distributed to the stockholders
     of record of Holding as a dividend on their shares of Holding's common
     stock. Upon the distribution, MGI became a majority owned subsidiary of C&D
     Fund IV. The transfer of 100% of the MCM Common Stock to MGI has been
     accounted for in a manner similar to the pooling-of-interests method due to
     the common ownership of MGI and Holding by C&D Fund IV following the
     distribution. On October 31, 1996, C&D Fund IV sold its ownership interest
     in Holding, which then ceased to be an affiliate of MGI.

     The Company believes that the accompanying consolidated condensed financial
     statements contain all adjustments (consisting of normal recurring
     accruals) necessary to present fairly the Company's consolidated financial
     position as of September 30, 1997 and 1996, its consolidated results of
     operations for the nine months ended September 30, 1997 and 1996, and its
     consolidated cash flows for the nine months ended September 30, 1997 and
     1996. The statements include the accounts of MGI and MCM and its
     subsidiaries McCarthy, Crisanti & Maffei, S.A., a 99.73% owned French
     subsidiary, and MCM Asia Pacific Company Limited, an 85% owned subsidiary.
     The 1996 financial statements and related amounts presented in the report
     represent those of MCM. All material intercompany accounts and transactions
     have been eliminated in consolidation. Certain information and note
     disclosure normally included in financial statements prepared in accordance
     with generally accepted accounting principles have been condensed or
     omitted. However, the Company's consolidated condensed financial statements
     for the year ended December 31, 1996 include the information and note
     disclosures normally included in financial statements prepared in
     accordance with generally accepted accounting principles and should be
     referred to for further information.

2.   Subsequent Events

     On August 1, 1997, MGI entered into an agreement to merge with a wholly
     owned subsidiary of Global Decisions Group LLC (the "Parent"). The
     outstanding common stock of MGI will be converted into units of capital of
     the Parent in the merger. As part of the agreements the stockholders of
     Cambridge Energy Research Associates, Inc. ("CERA") and the limited
     partners of Cambridge Energy Research Associates Limited Partnership ("CERA
     LP") have also agreed to exchange their outstanding stock of CERA and its
     limited partnership interest in CERA LP, respectively, for units of capital
     of the Parent. MGI and CERA will be wholly owned subsidiaries of the Parent
     following the merger and exchanges. Under the terms of the agreement, MCM
     will lend CERA up to $25,000,000, and CERA will use such funds and its
     available cash to make a distribution to CERA stockholders and to purchase
     a portion of the limited partnership interests in CERA LP. MCM anticipates
     generating the funds to be loaned to CERA from long-term third party
     borrowings and from MCM's available cash.

                          Independent Auditors' Report


The Board of Directors
Cambridge Energy Research Associates, Inc.:


         We have audited the accompanying consolidated balance sheets of
Cambridge Energy Research Associates, Inc. and subsidiary as of June 30, 1997
and 1996, and the related consolidated statements of income, stockholders'
deficit, and cash flows for each of the years in the three-year period ended
June 30, 1997. These consolidated financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

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

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Cambridge
Energy Research Associates, Inc. and subsidiary as of June 30, 1997 and 1996,
and the results of their operations and their cash flows for each of the years
in the three-year period ended June 30, 1997 in conformity with generally
accepted accounting principles.

(2)  Summary of Significant Accounting Policies

          (a)  Principles of Consolidation 
               The consolidated financial statements include the accounts of
                    the Company and its subsidiary, Cambridge Energy Research
                    Associates, L.P., which is 90 percent owned by the Company.
                    All significant intercompany accounts are eliminated upon
                    consolidation. The consolidated entity will hereafter be
                    referred to as the "Company."

          (b)  Use of Estimates
               The preparation of consolidated financial statements in
                    conformity with generally accepted accounting principles
                    requires management to make estimates and assumptions that
                    affect the reported amounts of assets and liabilities and
                    disclosure of contingent assets and liabilities at the date
                    of the financial statements and the reported amounts of
                    revenues and expenses. Actual results could differ from
                    those estimates.

          (c)  Fair Value of Financial Instruments
               Financial instruments of the Company consist of cash, accounts
                    receivable, accounts payable and accrued liabilities. The
                    carrying value of these financial instruments approximates
                    their fair value because of the short maturity of these
                    instruments.

          (d)  Property and Equipment
               Property and equipment are stated at cost and depreciated using
                    the straight-line method over periods ranging from two to
                    five years. Leasehold improvements are amortized over the
                    remaining lease term using the straight-line method.

          (e)  Revenue Recognition
               Retainer-service fees are billed at the inception of the contract
                    and revenue is recognized ratably over the contract term.
                    Revenues from consulting services are recognized on the
                    percentage-of-completion method. Losses are recognized when
                    they are known.

          (f)  Income Taxes
               The Company has elected S corporation status under the Internal
                    Revenue Code whereby it does not incur federal or most state
                    income taxes at the corporate level, as they are borne by
                    the Company's stockholders. The

                   Notes to Consolidated Financial Statements


                    Company does provide for French taxes on the income of its
                    Paris branch office.

               The Company uses the asset and liability method of accounting
                    for income taxes. Under the asset and liability method,
                    deferred tax assets and liabilities are recognized for the
                    future tax consequences attributable to differences between
                    the financial statement carrying amounts of existing assets
                    and liabilities and their respective tax bases. Deferred tax
                    assets and liabilities are measured using enacted tax rates
                    expected to apply to taxable income in the years in which
                    those temporary differences are expected to be recovered or
                    settled. The effect on deferred tax assets and liabilities
                    of a change in tax rates is recognized in income in the
                    period that includes the enactment date.

          (g)  Foreign Currency Translation
               Assets and liabilities of the foreign branch are translated at
                    the exchange rate as of the balance sheet date. For revenues
                    and expenses, the weighted average exchange rate for the
                    period has been used. Translation adjustments that result
                    from the translation of the foreign branch are reported as a
                    component of stockholders' deficit.

          (h)  Cash and Cash Equivalents
               For purposes of the statement of cash flows, the Company
                    considers all highly liquid debt instruments (purchased with
                    an original maturity of three months or less) to be cash
                    equivalents.

          (i)  Major Customers
               The Company's three largest customers accounted for
                    approximately 20%, 27% and 23% of total revenues for the
                    years ended June 30, 1997, 1996 and 1995, respectively.
                    Accounts receivable from these three customers represented
                    approximately 9% and 21% of the total accounts receivable
                    balance at June 30, 1997 and 1996, respectively. The Company
                    estimates an allowance for doubtful accounts based on the
                    creditworthiness of its customers, as well as general
                    economic conditions. Consequently, an adverse change in
                    those factors could affect the Company's estimate of its
                    allowance.

          (j)  Foreign Sales
               Foreign sales represented approximately 40%, 30% and 40% of
                    revenue for the years ended June 30, 1997, 1996 and 1995,
                    respectively.

          (k)  Company Bonuses
               For the years ended June 30, 1997, 1996 and 1995, the Company
                    distributed substantially all of its net earnings to
                    directors and employees of the Company in the form of a
                    bonus. This expense has been allocated between cost of
                    revenues and selling, general and administrative expenses.

(6)  Line of Credit

     At June 30,1997, the Company has a $1,750,000 line of credit agreement with
          a bank, with interest at prime plus 2%. The line of credit is secured 
          by the Company's accounts receivable and is guaranteed by the
          principal stockholders of the Company.

     As of June 30, 1997 and 1996, there were no amounts outstanding under the
          agreement.

(7)  Other Expense

     Other expenses include approximately $969,000, $436,000 and $529,000 in
          1997, 1996 and 1995 respectively, incurred in connection with the
          Company's ongoing review of potential strategic merger partners. 

(8)  Agreement with Investor

     In 1994, the Company entered into an agreement (the "Agreement") with
          another company (the "Investor") whereby the Investor acquired a 10
          percent ownership interest in newly formed Cambridge Energy Research
          Associates Limited Partnership ("CERA, L.P.") (a Delaware limited
          partnership) and the Company acquired a 90 percent ownership interest.
          The Company is the sole general partner of CERA, L.P. The Investor is
          the only limited partner. CERA, L.P. became the operating entity. At
          June 30, 1997 and 1996, the Company's only significant asset is its 90
          percent ownership interest in CERA, L.P.

     The Company contributed all of its assets to, and all of its liabilities
          were assumed by, CERA, L.P. in exchange for its 90 percent ownership
          interest. The Investor purchased its 10 percent interest from CERA,
          L.P. for $2,800,000 which was distributed by CERA, L.P. to the Company
          and then paid to the Company's stockholders as a special dividend.

     In conjunction with the Agreement, CERA, L.P. entered into an advisory
          agreement with the Investor under which CERA, L.P. is to provide
          professional services to the Investor over an initial three-year term
          (subject to early-termination rights of both parties).

     Until October 31, 1998, under certain provisions of the Agreement, CERA,
          L.P. could be obligated to repurchase, at fair market value, the
          Investor's ten percent interest.

(9)  Commitment

     Common Stock Redemption
     The Company is obligated to purchase terminated employees' shares of
          common stock of the Company, generally at appraised fair market value.
          In the event of a stockholder's death, the redemption price is funded
          in part by company-owned life insurance policies on the lives of
          certain stockholders.

(10) Subsequent Event 

     On August 1, 1997, the Company entered into an agreement with Global
          Decisions Group LLC (the Parent) in which the stockholders of the
          Company will exchange their outstanding stock of the Company for units
          of capital of the Parent. The Company will be a wholly owned
          subsidiary of the Parent following the exchange. In addition, the
          limited partner of CERA, L.P. also agreed to exchange its limited
          partnership interest in CERA, L.P. for units of capital of the Parent.
          Closing of this transaction is anticipated by the end of calendar
          year 1997.

of a completed and duly executed MGI Holder Information Form, substantially in
the form attached hereto as Exhibit H, be entitled to receive a certificate or
certificates representing the aggregate number of LLC Units (each, an "LLC
Certificate") into which the aggregate number of shares of MGI Common Stock
previously represented by such MGI Certificate or Certificates surrendered shall
have been converted pursuant to this Agreement. The Exchange Agent shall deliver
all LLC Certificates which each holder of MGI Common Stock is entitled to
receive pursuant to this Section 1.2.6(a) within ten Business Days following

theft or destruction of any such MGI Certificate or the delivery of such LLC
Certificates.

            (b) Endorsement of MGI Certificates; Transfer Taxes. If an LLC
Certificate is to be delivered to a Person other than the Person in whose name
the MGI Certificate surrendered in exchange therefor is registered, it shall be
a condition to delivery of such LLC Certificate that the MGI Certificate so
surrendered shall be properly endorsed or otherwise in proper form for transfer,
and that the Person requesting such LLC Certificate shall pay any transfer or
other Taxes required by reason of the payment to a Person other than the
registered holder of the MGI Certificate surrendered or establish to the
satisfaction of the Surviving Corporation that such Tax has been paid or is not
applicable.

            (c) Status of Certificates. Until surrendered in accordance with the
provisions of this Section 1.2.6, from and after the Effective Time, each MGI
Certificate (other than (i) MGI Certificates representing shares of MGI Common
Stock held in the treasury of the Surviving Corporation and (ii) Dissenting
Shares in respect of which appraisal rights are perfected) shall represent for
all purposes only the right to receive such number of LLC Units as determined in
the manner set forth in this Agreement and shall not itself represent an equity
interest in the Parent, which shall be represented only by LLC Units.

transfers on the stock transfer books of the Surviving Corporation of the shares
of MGI Common Stock that were outstanding immediately prior to the Effective

Stockholder in the CERA Stock Exchange.

            1.4 Exchange of GS LP Interest. At the Closing, the portion of the
GS Partnership Interest owned by GS LP immediately prior to the Closing shall be

Parent to GS LP, pursuant to a Contingent Option Agreement to be entered into at
the Closing by and between the Parent and GS LP, of an option (such option, the
"GS Contingent Option" and, together with the CERA Contingent Options, the
"Contingent Options") to purchase at a per LLC Unit price equal to $34.53 in the
event that the CERA CAGR shall be equal to or greater than 20%, 9,874 LLC Units,
as such number may adjusted pursuant to Section 1.8 (as so adjusted, the "GS

2000 or, in the event of the first to occur, prior to June 30, 2000, of a Sale
of the Parent or CERA Inc., a Spin-Off of CERA Inc. or a Public Offering, as of
the closing date of such Sale, Spin-Off or Public Offering, as the case may be,
10% of the Contingent LLC Units.

            1.5 Grant of LLC Units and Contingent LLC Units to CERA Management
Members. Promptly after the Closing Date, (i) (A) the Parent shall issue to CERA
Inc., for a purchase price per LLC Unit equal to the value per LLC Unit as of

Section 1.8, which purchase price shall be payable in cash or, at CERA Inc.'s
option, by delivery of an interest-bearing promissory note (which interest will
be payable in cash no less frequently than semi-annually) for such amount that
will be payable at any time upon demand by the Parent, and (B) CERA Inc.,
pursuant 


                                       11

as is set forth opposite such CERA Management Member's name on Exhibit A hereto,
and (ii) the Parent shall issue to CERA Inc. the right to purchase additional
LLC Units, for a purchase price per LLC Unit equal to its fair market value (as
determined in good faith by the Board of the Parent) at the time such Contingent

CERA Inc. shall grant to each such CERA Management Member, pursuant to a CERA
LLC Unit Grant Agreement, a right to receive such additional LLC Units, as
follows: in the event that the CERA CAGR shall be equal to or greater than 16%,
CERA Inc. shall be entitled to purchase up to 7.125% of the Contingent LLC
Units, and each such CERA Management Member shall be entitled to receive, as of
June 30, 2000 or, in the event of the first to occur, prior to June 30, 2000, of
a Sale of the Parent or CERA Inc., a Spin-Off of CERA Inc. or a Public Offering,
as of the closing date of such Sale, Spin-Off or Public Offering, as the case
may be, a number of Contingent LLC Units equal to the product of (x) (A) 7.125%
of the Contingent LLC Units divided by (B) the aggregate number of LLC Units
granted to the CERA Management Members pursuant to clause (i) of this Section
1.5 and (y) the number of LLC Units so granted to such CERA Management Member.
If the employment of such CERA Management Member with (or, if such CERA
Management Member is a consultant to rather than an employee of CERA Inc. or any
of its Subsidiaries, the provision of services by such CERA Management Member
to) CERA Inc. or any of its Subsidiaries is terminated prior to June 30, 2000
or, in the event that, prior to June 30, 2000, a Sale of the Parent or CERA
Inc., a Spin-Off of CERA Inc. or a Public Offering occurs, prior to the closing
date of such Sale, Spin-Off or Public Offering, and (i) such employment or
provision of services was terminated voluntarily by such CERA Management Member
or by CERA Inc. or such Subsidiary for Cause (as defined in the CERA Option

services, the right of such CERA Management Member to receive Contingent LLC
Units shall terminate, and such CERA Management Member shall not be entitled to
any payment in respect thereof, or (ii) such employment or provision of services
was terminated for any other reason, then the right of such CERA Management
Member to receive Contingent LLC Units shall terminate and, in lieu thereof,
CERA Inc. shall pay to such CERA Management Member (or his or her permitted
transferees as provided below), promptly 


                                       12
<PAGE>   189

after such termination of employment or provision of services, an amount in cash
equal to the fair market value (as determined in good faith by the Board of the
Parent), as of the date of such termination of employment or provision of
services, of the number, if any, of Contingent LLC Units that would have been
issuable to such CERA Management Member, based on the CERA CAGR as of such date
(as determined in good faith by CERA Inc.), if the closing of a Nonqualifying
Sale had occurred on such date. The right of each CERA Management Member to
receive Contingent LLC Units pursuant to this Section 1.5 shall be transferable
only (1) by will or the laws of descent or distribution upon the death of such
CERA Management Member or (2) to a trust the only actual beneficiaries under
which are such CERA Management Member and/or one or more of such CERA Management
Member's brothers and sisters (whether by whole or half blood), spouse,
ancestors and lineal descendants, provided that the Parent shall only be
required to treat any such transferee as a permitted transferee for purposes of
this Article I if it shall have received notice of such transfer.

            1.6 Calculation of CERA CAGR. (a) Not later than (x) 15 days after
the audited financial statements of CERA Inc. for the fiscal year ended June 30,
2000 shall have been completed and delivered to the Parent or (y) if a Sale of
the Parent or CERA Inc., a Spin-Off of CERA Inc. or a Public Offering shall be
contemplated, five days prior to the scheduled closing date of such Sale,
Spin-Off or Public Offering, the Board of the Parent shall determine, reasonably
and in good faith, the CERA CAGR, and the Parent shall send a written notice to
each Stockholder who participated in the CERA Stock Exchange, to GS LP and to
each CERA Management Member who, as of the date of such notice, shall still have
a right to receive Contingent LLC Units pursuant to Section 1.5 (or any
permitted transferees of any of the foregoing), setting forth (i) the revenues
of CERA Inc. for such fiscal year or, in the case of such Sale, Spin-Off or
Public Offering, for the applicable period prior to such scheduled closing date,
in each case as determined for purposes of calculating the CERA CAGR, (ii) the
CERA CAGR and (iii) the number of Contingent LLC Units, if any, which each
Stockholder, GS LP and each such CERA Management Member who shall still have a
right to receive Contingent LLC Units pursuant to Section 1.5 (or any permitted
transferees of any of the foregoing) have become entitled to receive (subject,
in the case of such CERA Management Members, to the payment by CERA Inc. of the
purchase price for the Contingent LLC Units to be issued to such CERA Management
Members) pursuant to Sections 1.3, 1.4 and 1.5.


                                       13
<PAGE>   190

The determination by the Parent, as set forth in such notice, of the CERA CAGR
and the number of Contingent LLC Units to be issued shall, in the absence of
fraud, be final, conclusive and binding on the Stockholders, GS LP and the CERA
Management Members.

            (b) In the case of clause (x) of Section 1.6(a), effective
immediately upon the transmittal of the notice referred to in Section 1.6(a),
or, in the case of clause (y) of Section 1.6(a), effective immediately prior to
the closing of the Sale, Spin-Off or Public Offering referred to in such Section
1.6(a), each such Stockholder (or any permitted transferees of any of the
foregoing) and GS LP shall be deemed, without any further action on the part of
the Parent or any such Stockholder (or any permitted transferees of any of the
foregoing) or GS LP, to be the owner, as of June 30, 2000 or immediately prior
to the closing of such Sale, Spin-Off or Public Offering, as the case may be, of
the respective number of Contingent LLC Units set forth in such notice. In the
case of clause (x) of Section 1.6(a), effective immediately upon the later of
(i) the transmittal of the notice referred to in Section 1.6(a) and (ii) the
payment by CERA Inc. of the purchase price for the Contingent LLC Units to be
issued to CERA Management Members, or, in the case of clause (y) of Section
1.6(a), effective immediately prior to the closing of the Sale, Spin-off or
Public Offering referred to in such Section 1.6(a) (provided that CERA Inc.
shall have paid the purchase price for such Contingent LLC Units), each CERA
Management Member who shall still have a right to receive Contingent LLC Units
pursuant to Section 1.5 (or each of his or her permitted transferees) shall be
deemed, without any further action on the part of the Parent, CERA Inc. or such
CERA Management Member or permitted transferee, to be the owner, as of June 30,
2000 or immediately prior to the closing of such Sale, Spin-Off or Public
Offering, as the case may be, of the respective number of Contingent LLC Units
set forth in such notice. The Parent shall send to each such Stockholder, GS LP,
each such CERA Management Member and each such permitted transferee a
certificate or certificates representing such Contingent LLC Units promptly
after delivery of the notice referred to in Section 1.6(a).

            (c) The Parent recognizes and understands that a significant portion
of the consideration to be received by the Stockholders and GS LP in the CERA
Stock Exchange and the GS Partnership Interest Exchange, respectively, is
contingent and based upon the level of growth in revenues achieved by CERA Inc.
during the three-year period between 


                                       14
<PAGE>   191

June 30, 1997 and June 30, 2000. Accordingly, the Parent agrees to cooperate
with CERA Inc. in CERA Inc.'s efforts to achieve the requisite level of revenue
growth, principally by providing CERA Inc.'s management with the authority to
manage and operate CERA Inc.'s business, subject to the reasonable oversight of
CERA Inc.'s Board of Directors.

            1.7 No Fractional LLC Units. No certificates for fractions of LLC
Units shall be issued pursuant to Section 1.2, 1.3, 1.4, 1.5 or 1.6. If the
conversion of a Person's aggregate holdings of MGI Common Stock, or the
aggregate number of LLC Units issuable to a Person at any time pursuant to the
CERA Stock Exchange, the GS Partnership Interest Exchange or a Contingent Option
or in connection with the Contingent LLC Units, results in a fractional LLC
Unit, the aggregate number of LLC Units that such Person shall be entitled to
receive shall be rounded to the nearest whole LLC Unit and, in the event that
such aggregate number of LLC Units shall be rounded down, such Person shall not
be entitled to any payment in respect of such fractional LLC Unit.

            1.8 Adjustments to Per Share MGI Allocated LLC Units, etc. The
number of Per Share MGI Allocated LLC Units, CERA Allocated LLC Units, CERA
Contingent Option LLC Units, Contingent LLC Units, GS Allocated LLC Units and GS
Contingent Option LLC Units set forth in this Agreement represents the
respective numbers of LLC Units initially agreed upon by the parties hereto.
Prior to the Closing, MGI, the Founding Stockholders and GS LP may agree upon
revised numbers of such LLC Units, such that the agreed-upon value per LLC Unit
at the time of the Closing shall be equal to $10.00. In such case, the
respective numbers of Per Share MGI Allocated LLC Units, CERA Allocated LLC
Units, CERA Contingent Option LLC Units, Contingent LLC Units, GS Allocated LLC
Units and GS Contingent Option LLC Units shall be adjusted by multiplying each
such number by the quotient obtained by dividing (i) the value per LLC Unit at
the time of the Closing that would result if the initial numbers of LLC Units
referred to above were not to be so revised by (ii) $10.00. In the event that
the numbers of such LLC Units are not so revised prior to the Closing pursuant
to this Section 1.8, the value per LLC Unit at the time of the Closing shall be
deemed to be equal to (A) the fair market value of the partnership interests in
CERA LP as of the Closing Date (as determined by Houlihan Valuation Associates
in the valuation report with respect to CERA LP to be prepared and delivered by
it at or prior to the Closing) 


                                       15

minus the amount of the CERA Cash Distribution divided by (B) 1,500,000.

            1.9 Treatment of the Transactions for Income Tax Purposes. The
parties hereto agree that:

            (a) For Income Tax purposes, the conversion of MGI Common Stock into
      LLC Units, and the conversion of common stock of Merger Sub into common
      stock of the Surviving Corporation, in each case pursuant to the Merger,
      shall be treated as a contribution of such MGI Common Stock to the Parent
      in exchange for such LLC Units pursuant to section 721(a) of the Code.

            (b) For Income Tax purposes, the exchange of CERA Common Stock for
      LLC Units, Contingent LLC Units and CERA Contingent Options pursuant to
      the CERA Stock Exchange shall be treated as a contribution of such CERA
      Common Stock to the Parent in exchange for such LLC Units, such Contingent
      LLC Units and the right to acquire LLC Units upon exercise of the CERA
      Contingent Options pursuant to section 721(a) of the Code.

            (c) For Income Tax purposes, the exchange of the GS Partnership
      Interest owned by GS LP following the CERA Cash Distribution for LLC
      Units, Contingent LLC Units and GS Contingent Options pursuant to the GS
      Partnership Interest Exchange shall be treated as a contribution of such
      GS Partnership Interest to the Parent in exchange for such LLC Units, such
      Contingent LLC Units and the right to acquire LLC Units upon exercise of
      the GS Contingent Options pursuant to section 721(a) of the Code.

            (d) For Income Tax purposes, the fair market value of such MGI
      Common Stock, CERA Common Stock and GS Partnership Interest at the time of
      the contribution thereof for Income Tax purposes set forth in paragraphs
      (a), (b) and (c), respectively, of this Section 1.8 shall be equal to the
      values set forth therefor on Schedule B to the Amended and Restated
      Limited Liability Company Agreement of the Parent, to be dated as of the
      Closing Date (the "LLC Agreement").

            (i) Disclosure. Each subsection of Section 2.1.6 of the CERA
Disclosure Letter sets forth, for each relevant item set forth in such
subsection thereof, the name of the entity, the taxing jurisdiction, the type of
Tax and the taxable period or periods involved.

            2.1.7. Properties and Assets. (a) Except insofar as would not have,
or reasonably be expected to have, a CERA Material Adverse Effect, each of CERA
LP and CERA Inc. has good and valid title to, or otherwise has sufficient and
legally enforceable right to use, all of the properties and assets (real,
personal or mixed, tangible or intangible, including Intellectual Property),
used or held for use in connection with, necessary for the conduct of, or
otherwise material to, the businesses conducted by it (the "CERA Assets").
Except as set forth in Section 2.1.7(a) of the CERA Disclosure Letter, the CERA
Assets that are owned by CERA Inc. or CERA LP are owned free and clear of any
Liens other than (i) liens for Taxes not yet due and payable or that are being
contested in good faith and by appropriate proceedings, (ii) statutory liens
incurred in the ordinary course of business that, individually and in the
aggregate, have not had and would not reasonably be expected to have a CERA
Material Adverse Effect, and (iii) encumbrances and easements that do not
materially detract from the value or materially interfere with the use of the
properties affected thereby (the exceptions described in the foregoing clauses
(i), (ii) and (iii) being referred to as "Permitted CERA Liens").

            (b) Neither CERA Inc. nor CERA LP owns any real property. Section
2.1.7(b) of the CERA Disclosure Letter contains a complete and correct list of
all real property leases, subleases and occupancy agreements to which either
CERA LP or CERA Inc. is a party (each, a "CERA Lease") setting forth the
address, landlord and tenant for each CERA Lease. CERA Inc. and CERA LP have
delivered to MGI and the Parent correct and complete copies of the CERA Leases.
Except insofar as would not have, or reasonably be expected to have, a CERA
Material Adverse Effect, (i) each CERA Lease, other than the CERA Lease with
respect to CERA LP's principal offices in Cambridge, Massachusetts, is legal,
valid, binding, in full force and effect and enforceable against CERA Inc. or
CERA LP, as the case may be, and, to the knowledge of any Stockholder, GS LP,
CERA Inc. or CERA LP, against the other parties thereto, (ii) neither CERA LP
nor CERA Inc. is in default, violation or breach under any such CERA Lease, and
no event has occurred and is continuing that constitutes or, with notice or the
passage of time or 


                                       24
<PAGE>   201

both, would constitute a default, violation or breach under any such CERA Lease
and (iii) each such CERA Lease grants the tenant under such CERA Lease the right
to use and occupy the premises and rights demised and intended to be demised
thereunder, which right is sufficient for the purposes for which such premises
and rights are or are contemplated to be used or occupied by such tenant. The
CERA Lease with respect to CERA LP's principal offices in Cambridge,
Massachusetts (the "CERA Headquarters Lease") is legal, valid, binding, in full
force and effect and enforceable against CERA Inc. or CERA LP, as the case may
be, and, to the knowledge of any Stockholder, GS LP, CERA Inc. or CERA LP, the
other parties thereto. Neither CERA LP nor CERA Inc. is in default, violation or
breach in any material respect under the CERA Headquarters Lease, and no event
has occurred and is continuing that constitutes or, with notice or the passage
of time or both, would constitute a default, violation or breach under the CERA
Headquarters Lease that would reasonably be expected to have a CERA Material
Adverse Effect. The CERA Headquarters Lease grants the tenant thereunder the
right to use and occupy the premises and rights demised and intended to be
demised thereunder, which right is sufficient for the purposes for which such
premises and rights are or are contemplated to be used or occupied by such
tenant.

            2.1.8. Contracts. Section 2.1.8 of the CERA Disclosure Letter sets

(or will receive) payments or other benefits even if not a party to such
agreement: (a) each client party to any contract or group of contracts,

bonus, change in control and other similar agreements or arrangements involving,
during the 10-month period ended April 30, 1997 (or reasonably expected as of
the date hereof to involve in any fiscal year of CERA Inc. commencing after June
30, 1997), accruals (for financial reporting purposes) by CERA Inc. or CERA LP
in excess of $25,000 with respect to any particular such agreement or
arrangement or in excess of $100,000 with respect to all such agreements and
arrangements in the aggregate, (d) any contracts or other documents that on or
after the Closing Date substantially limit or will limit the freedom of CERA LP
or CERA Inc. to compete in any line of business and (e) any other contract or
commitment that is material to CERA LP, CERA Inc. or their respective businesses
or not made in the ordinary course of business. Neither CERA LP, CERA Inc., any
Stockholder, GS LP nor, to the knowledge of any Stockholder, GS LP, CERA LP or
CERA Inc., any other party, is in breach or default in any material respect
under any of the agreements, contracts or commitments set forth in Section 2.1.8
of the CERA Disclosure Letter and, except as set forth in Section 2.1.8 of the
CERA Disclosure Letter, there exists no event or condition (including the
Transactions) which has resulted or would result in a material breach or default
thereunder upon the giving of notice, the passage of time or both. All the
agreements, contracts and commitments set forth in Section 2.1.8 of the CERA
Disclosure Letter are legal, valid, binding, in full force and effect and
enforceable against CERA LP, CERA Inc. or the applicable Founding Stockholder,
as the case may be, except for such agreements, contracts and commitments as
would not reasonably be expected to result in a CERA Material Adverse Effect.

            2.1.9. Intellectual Property. (a) Schedule of Intellectual Property.

all other material Intellectual Property (other than unregistered copyrights)
used or held for use in connection with, necessary for the conduct of, or
otherwise material to the business and operations of CERA Inc. and CERA LP (the
"CERA Intellectual Property") and sets forth the owner and nature of the
interest of CERA LP or CERA Inc. therein. All of the material copyrights used or
held for use in connection with, necessary for the conduct of, or otherwise
material to the business and operations of CERA Inc. and CERA LP have been duly
registered. Section 2.1.9(a) of the CERA Disclosure Letter sets forth a correct
and complete list of all material licenses, sublicenses or other similar
material agreements (including any amendments thereto) to which CERA Inc. or
CERA LP is a party, by which either of them is bound or under which either of
them receives any benefits, relating to any CERA Intellectual Property (the
"CERA Licenses"). Each CERA License is legal, valid, binding, in full force and
effect and enforceable against CERA LP or CERA Inc., as applicable, and neither
CERA Inc., CERA LP nor, to the knowledge of any Stockholder, GS LP, CERA LP or
CERA Inc., any other party thereto is in breach or default in any material
respect under any CERA License and there exists no event or condition (including

the CERA Disclosure Letter, the business and operations of CERA Inc. and CERA LP
as currently conducted do not infringe or otherwise conflict with any rights of
any Person in respect of any Intellectual Property, and neither CERA Inc., CERA
LP nor any of their Affiliates has received notice or has actual knowledge of
any such infringement or conflict, except such infringements and conflicts as,
individually and in the aggregate, have not had and would not reasonably be
expected to have a CERA Material Adverse Effect. To the knowledge of any of the
Stockholders, GS LP, CERA Inc. or CERA LP, none of the CERA Intellectual
Property owned by CERA Inc. or CERA LP is being materially infringed or, other
than pursuant to license agreements in the ordinary course of business,
otherwise materially used or available for use by any Person other 


                                       27
<PAGE>   204

than CERA Inc. or CERA LP. No CERA Intellectual Property owned by CERA Inc. or
CERA LP is subject to any outstanding Order or agreement restricting the use
thereof by CERA Inc. or CERA LP with respect to its business or restricting the
licensing thereof by CERA Inc. or CERA LP to any Person. Each trademark, trade
dress or service mark and any registration or application therefor, mask work,
copyright registration or application therefor included in any CERA Intellectual
Property owned by CERA Inc. or CERA LP is in proper form and has been properly
maintained in all material respects and has otherwise been duly registered with,
filed in or issued by, as the case may be, the United States Patent and
Trademark Office, the United States Copyright Office or such other applicable
filing offices, domestic or foreign, and CERA Inc. or CERA LP has taken
reasonable actions to ensure protection under any applicable laws, and such
registrations, filings, issuances and other actions remain in full force and
effect. Except as set forth in Section 2.1.9(b) of the CERA Disclosure Letter,
neither CERA Inc. nor CERA LP has entered into any agreement to indemnify any
other Person against any charge of infringement, dilution or violation of
Intellectual Property rights, other than pursuant to any such agreements entered
into in connection with the use of commercially available information systems
applications or entered into in the ordinary course of business in connection
with the provision to clients of reports by CERA Inc. or CERA LP.

Disclosure Letter is a complete and correct list of all of the insurance
policies, including, without limitation, key man insurance policies, which are

businesses conducted by CERA Inc. or CERA LP, the CERA Assets or both, together
with a description with respect to each policy of the amount and types of
coverage, limits and deductibles, inception and expiration dates and insurance
carrier. CERA Inc. and CERA LP have made available to MGI complete and correct
copies of all such policies together with all riders and amendments thereto.
Such policies are in full force and effect and all premiums due thereon have

and limitations as to deductibles and self-insured retentions, are, to the
knowledge of any of the Stockholders, GS LP, CERA Inc. or CERA LP, adequate and
customary to insure against risks to which CERA Inc., CERA LP or the CERA Assets
are normally exposed in the operation of the businesses conducted by CERA Inc.

            2.1.16. ERISA. (a) Section 2.1.16(a) of the CERA Disclosure Letter
sets forth a complete and correct list of each "employee benefit plan," as such

compensation, severance, termination, retention, change of control,
equity-based, performance or other employee or retiree benefit or compensation
plan, program, arrangement, agreement, policy or understanding, whether written
or unwritten, maintained, sponsored or contributed to by CERA Inc. or with
respect to which CERA Inc. is obligated to contribute or is a party
(collectively, the "CERA Plans"). CERA LP does not maintain, sponsor, contribute
to or have an obligation to contribute to, and is not a party to, any such
employee benefit plan or employee or retiree benefit or compensation plan,
program, arrangement, agreement, policy or understanding. With respect to each
CERA Plan, CERA Inc. or CERA LP have provided MGI complete and correct copies of

written, and (ii) to the extent applicable to such CERA Plan, all trust
agreements, insurance contracts or other funding agreements or arrangements, the
most recent actuarial and trust report, the most recent Form 5500 required to
have been filed with the IRS and all schedules thereto, the most recent IRS
determination letter, all current summary plan descriptions and any and all
amendments to any such document. No other trade or business, whether or not
incorporated, is currently or, within the preceding six years, has been required
to be treated as a "single employer" together with CERA LP or CERA Inc. pursuant
to clause (b), (c) or (m) of section 414 of the Code.

            (b) Each CERA Plan intended to be qualified under section 401(a) of
the Code, and the trust (if any) forming a part thereof, has received a
favorable determination letter from the IRS as to its qualification under the
Code and to the effect that each such trust is exempt from taxation under
section 501(a) of the Code, and nothing has occurred since the date of such
determination letter that could reasonably be expected to adversely affect such
qualification or tax-exempt status.

            (c) No CERA Plan is (i) subject to section 412 of the Code or
section 302 or Title IV of ERISA, (ii) a "multiemployer plan" within the meaning
of section 4001(a) of ERISA or (iii) a "multiple employer plan" within the
meaning of section 4064 of ERISA.

            (d) Neither CERA Inc. nor CERA LP has incurred (either directly or
indirectly, including as a result of an indemnification obligation) any material
liability under or pursuant to Title I or IV of ERISA or the penalty, excise Tax
or joint and several liability provisions of the Code relating to employee
benefit plans and, to the knowledge of any of the Stockholders, GS LP, CERA Inc.
or CERA LP, no event, transaction or condition has occurred or exists that could
result in any such liability to CERA Inc. or CERA LP or, following the Closing,
the Parent or any of its Affiliates. All contributions and premiums required to
have been paid by CERA Inc. to any CERA Plan under the terms of any such CERA
Plan or its related trust, insurance contract or other funding arrangement, or
pursuant to any applicable law (including ERISA and the Code) or collective
bargaining agreement have been paid when due and, and to the extent not yet due,
have been properly and adequately reflected on the CERA Financial Statements.

            (e) Each of the CERA Plans has been operated and administered in all
respects in compliance with its terms and all applicable laws except for any
failure so to comply that, individually and in the aggregate, has not had and
would not reasonably be expected to have or result in a CERA Material Adverse
Effect. There are no material pending or, to the knowledge of any of the
Stockholders, GS LP, CERA LP or CERA Inc., threatened claims by or on behalf of
any of the CERA Plans, by any current or former director, officer or employee of
CERA Inc. or CERA LP or otherwise involving any such CERA Plan or the assets of
any CERA Plan (other than routine claims for benefits, all of which have been
fully reserved for on the CERA Financial Statements).

            (f) The consummation of the transactions contemplated by this
Agreement will not result in an increase in the amount of compensation or
benefits or the acceleration of the vesting or timing of payment of any
compensation or benefits payable to or in respect of or accrued on behalf of any
current or former director, officer or employee of CERA Inc. or CERA LP or
entitle any such director, officer or employee to any severance or similar
compensation or benefits.

            2.1.17. Brokers. There is no agreement that obligates any party to
pay any broker's or finder's fee or commission or similar compensation to any
Person acting on behalf of the Stockholders, GS LP, CERA Inc. or CERA LP with
respect to any sale of CERA Inc., of CERA LP, the assets of CERA Inc. and/or
CERA LP or any equity interest or part-


                                       32

nership interest in either of them, other than to Wm. Sword & Co. and Mr. Edward

respectively.

GS LP, CERA LP or CERA Inc., threatened to cancel, terminate or reduce, a

reorganization or similar proceeding pending against any of the MCM Companies.
MCM is a corporation duly organized, validly existing and in good standing under
the laws of the State of New York. Each of the MCM Companies is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation, formation or organization (as the case may be), has all necessary
corporate power and authority to own, lease or license the property owned or
used by it, and to conduct its business as and in the places where its business
is now being conducted. Section 2.4.4(ii) of the MGI Disclosure Letter sets
forth a description (including the name of each party thereto and of each
written agreement relating thereto or, if no such written agreement exists, a
description of the material terms thereof) of each joint venture or partnership,
or similar agreement or arrangement involving a sharing of profits or expenses
during the year ended December 31, 1996 in excess of $10,000 in the case of any
such agreement or arrangement or $25,000 in the aggregate in the case of all
such agreements or arrangements, to which any MCM Company is a party or by which
any of them may be bound. Each MCM Company is duly qualified or licensed to do
business and is in good standing in each of the jurisdictions in which the
nature of its business or the properties owned or leased by it makes such
qualification or licensing necessary, except for such jurisdictions where the
failure to so qualify or be licensed does not have and would not reasonably be
expected to have an MGI Material Adverse Effect.

            2.4.5. Capitalization; Ownership. (a) The authorized capital stock
of MGI consists of (i) 500,000 shares of MGI Class A Common Stock, of which
330,000 shares are issued and outstanding as of the date hereof, (ii) 60,000
shares of MGI Class B Common Stock, of which no shares are issued and
outstanding as of the date hereof and (iii) 80,000 shares of MGI Class C Common
Stock, of which 17,400 shares are issued and outstanding as of the date hereof.
All of the outstanding shares of MGI Common Stock have been duly authorized and
validly issued and are fully paid and nonassessable.

            (b) Section 2.4.5(b) of the MGI Disclosure Letter sets forth a
complete and correct (i) list of all members of the MCM Group other than MGI and
(ii) description of the authorized stock or other equity interests of each
member of the MCM Group (other than MGI) and the amount of such stock or other
equity interests that are issued and outstanding as of the date hereof. All of
such outstanding shares of stock 


                                       38
<PAGE>   215

or other equity interests of each member of the MCM Group (other than MGI) have

All of such outstanding shares of capital stock or other equity interests of
each member of the MCM Group (other than MGI) are owned, beneficially and of
record, by the Person listed in Section 2.4.5(b) of the MGI Disclosure Letter as
being the owner of such shares or other equity interests. None of the MCM
Companies holds, beneficially or of record, any capital stock or other equity
interests of any Person that is not an MCM Company, except for publicly traded
equity securities not exceeding 10% of the outstanding equity securities of such
Person or in connection with short-term instruments or cash management.

            (c) Other than as set forth in the Registration and Participation
Agreement and as set forth in Section 2.4.5(c) of the MGI Disclosure Letter,
there are no preemptive or similar rights with respect to the MGI Common Stock
or any other equity securities of any MCM Company. Except for this Agreement and
the Existing MGI Options, no (i) subscriptions, options, warrants, conversion or
other rights, agreements, commitments, arrangements or understandings of any
kind obligating any MCM Company to issue or sell any shares of capital stock of
any MCM Company or any other equity interests therein or (ii) securities
convertible into or exchangeable for any such shares or interests are
outstanding, and no authorization therefor has been given. Section 2.4.3 of the
MGI Disclosure Letter sets forth, as of the date hereof, a correct and complete
list of all holders of Existing MGI Options, setting forth with respect to each
such holder (x) the number and class of shares of MGI Common Stock subject to
the Existing MGI Options held by such holder and (y) the exercise price of the
Existing MGI Options held by such holder. Except for the MGI Management Stock
Subscription Agreements, there are no outstanding contractual obligations of any
MCM Company to repurchase, redeem or otherwise acquire any MGI Common Stock or
any other equity securities of any MCM Company.

            2.4.6. Financial Statements. MGI has delivered to the Founding
Stockholders and GS LP complete and correct copies of the audited consolidated

            The MGI Financial Statements present fairly in all material respects
the financial position of the MCM Group as at the respective dates or for the
respective periods thereof, and have been prepared in accordance with GAAP
applied on a consistent basis throughout the periods presented in the MGI

(c) for liabilities and obligations that are incurred in the ordinary course of

obligations that are expressly contemplated by this Agreement and (e) for
liabilities and obligations that, individually or in the aggregate, are not and

other MCM Company, in the case of clause (A), other than in the ordinary course
of business consistent with past practices, (iv) no MCM Company has entered into
any agreement, contract or commitment (other than this Agreement) for the sale

a whole, the assets of any such MCM Company or any equity interests in any such
MCM Company, and (v) none of the applicable MCM Companies has taken any action

duly and timely paid: (i) all Taxes shown to be due on the MCM Returns and (ii)
all material Taxes due and payable on or before the Closing Date that are or may

Taxes required to be paid or withheld by or on behalf of any MCM Company or for

            (b) Extensions, etc. Except as set forth in Section 2.4.9(b) of the
MGI Disclosure Letter, no written agreement or other document extending, or
having the effect of extending, the period of assessment or collection of any

effect to all valid extensions of time for filing) on or before the Closing
Date. Except as set forth in Section 2.4.9(d) of 


                                       42
<PAGE>   219

the MGI Disclosure Letter, (i) no MCM Taxes or MCM Employment and Withholding
Taxes have been asserted by any Governmental Authority since January 1, 1994 to
be due, (ii) no revenue agent's report or written assessment for Taxes has been
issued by any Governmental Authority in the course of any audit that has been
completed since July 1, 1993 with respect to MCM Taxes or MCM Employment and
Withholding Taxes and (iii) no issue has been raised by any Governmental
Authority in the course of any audit that has not been completed with respect to

            (e) Section 1445(a) of the Code. No amount will be required to be

subsection thereof, the name of the MCM Company, the taxing jurisdiction, the
type of Tax and the taxable period or periods involved.

            2.4.10. Properties and Assets. (a) Except insofar as would not have,
or reasonably be expected to have, an MGI Material Adverse Effect, each MCM
Company has good and valid title to, or otherwise has sufficient and legally
enforceable right to use, all of the properties and assets (real, personal or
mixed, tangible or intangible, including Intellectual Property), used or held
for use in connection with, necessary for the conduct of, or otherwise material
to, the businesses conducted by it (the "MGI Assets"). The MGI Assets that are
owned by any MCM Company are owned free and clear of any Liens other than (i)
liens 


                                       43
<PAGE>   220

for Taxes not yet due and payable or that are being contested in good faith and
by appropriate proceedings, (ii) statutory liens incurred in the ordinary course
of business that, individually and in the aggregate, have not had and would not
reasonably be expected to have an MGI Material Adverse Effect, and (iii)
encumbrances and easements that do not materially detract from the value or
materially interfere with the use of the properties affected thereby (the
exceptions described in the foregoing clauses (i), (ii) and (iii) being referred
to as "Permitted MCM Liens").

            (b) None of the MCM Companies owns any real property. Section
2.4.10(b) of the MGI Disclosure Letter contains a complete and correct list of
all real property leases, subleases and occupancy agreements to which any MCM
Company is a party (each, an "MGI Lease") setting forth the address, landlord
and tenant for each MGI Lease. MGI has delivered to the Founding Stockholders
and GS LP correct and complete copies of the MGI Leases. Except insofar as would
not have, or reasonably be expected to have, an MGI Material Adverse Effect, (i)
each MGI Lease, other than the MGI Lease with respect to MCM's principal offices
in New York, New York, is legal, valid, binding, in full force and effect and
enforceable against the applicable MCM Company and, to the knowledge of MGI,
against the other parties thereto, (ii) the applicable MCM Company is not in
default, violation or breach under any such MGI Lease, and no event has occurred
and is continuing that constitutes or, with notice or the passage of time or
both, would constitute a default, violation or breach under any such MGI Lease,
and (iii) each such MGI Lease grants the tenant under such MGI Lease the right
to use and occupy the premises and rights demised and intended to be demised
thereunder, which right is sufficient for the purposes for which such premises
and rights are or are contemplated to be used or occupied by such tenant. The
MGI Lease with respect to MCM's principal offices in New York, New York (the
"MCM Headquarters Lease") is legal, valid, binding, in full force and effect and
enforceable against MCM and, to the knowledge of MGI, the other parties thereto.
MCM is not in default, violation or breach in any material respect under the MCM
Headquarters Lease, and no event has occurred and is continuing that constitutes
or, with notice or the passage of time or both, would constitute a default,
violation or breach under the MCM Headquarters Lease that would reasonably be
expected to have an MGI Material Adverse Effect. The MCM Headquarters Lease
grants the tenant thereunder the right to use and occupy the premises and rights
demised and intended to be demised thereunder, which right is sufficient for the
purposes for 


                                       44
<PAGE>   221

which such premises and rights are or are contemplated to be used or occupied by
such tenant.

            2.4.11. Contracts. Section 2.4.11 of the MGI Disclosure Letter sets
forth a correct and complete list, as of the date hereof, of all agreements,
contracts and commitments (including the names of each party thereto), or, in
the case of clause (b) below, of all customers party to all agreements,
contracts and commitments, of the following types (taking into account any
specified dollar thresholds) to which any MCM Company is a party or by or
pursuant to which any MCM Company is bound or is receiving (or will receive)
payments or other benefits even if not a party to such agreement: (a) all
contracts with vendor distribution firms, including any oral arrangements
relating thereto or extensions thereof, (b) each customer party to any contract
or group of contracts, including any oral arrangements relating thereto or
extensions thereof, with respect to which customer any MCM Company expects, as
of the date hereof, to receive, during the year ending December 31, 1997,
revenues in excess of $200,000 in the aggregate, (c) loan agreements and other
agreements relating to indebtedness for borrowed money, promissory notes, bonds,
guaranties, letters of credit, credit facilities, mortgages, security
agreements, pledge agreements, deferred purchase price agreements, sale and
leaseback agreements or similar agreements, (d) (i) employment, consulting and
agency agreements or arrangements involving, during the twelve-month period
ended March 31, 1997, accruals (for financial reporting purposes) by any MCM
Company in excess of $25,000 with respect to any particular such agreement or
arrangement, other than any employment or consulting agreement or arrangement
involving accruals during such period of less than $90,000 that is terminable at
will or subject to such limitations on termination as may be imposed by
Applicable Law, by the applicable employer or entity being provided with
consulting services, without the payment of any amount in excess of such amount
as may be required by Applicable Law, or (ii) severance, retention, bonus,
change in control and other similar agreements or arrangements involving, during
the twelve-month period ended March 31, 1997 (or reasonably expected as of the
date hereof to involve in any calendar year commencing on or after January 1,
1997), accruals (for financial reporting purposes) by any MCM Company in excess
of $25,000 with respect to any particular such agreement or arrangement or in
excess of $100,000 with respect to all such agreements and arrangements in the
aggregate, (e) any contracts or other documents that on or after the Closing
Date substantially limit or will limit the


                                       45
<PAGE>   222

freedom of any MCM Company to compete in any line of business and (f) any other
contract or commitment that is material to any MCM Company or its business or
not made in the ordinary course of business. Neither the applicable MCM Company
nor, to the knowledge of MGI, any other party, is in breach or default in any
material respect under any of the agreements, contracts or commitments set forth
in Section 2.4.11 of the MGI Disclosure Letter and, except as set forth in
Section 2.4.11 of the MGI Disclosure Letter, there exists no event or condition
(including the Transactions) which has resulted or would result in a material
breach or default thereunder upon the giving of notice, the passage of time or
both. All the agreements, contracts and commitments set forth in Section 2.4.11
of the MGI Disclosure Letter are legal, valid, binding, in full force and effect
and enforceable against the applicable MCM Company, except for such agreements,
contracts and commitments as would not reasonably be expected to result in an
MGI Material Adverse Effect.

            2.4.12. Intellectual Property. (a) Schedule of Intellectual
Property. Section 2.4.12(a) of the MGI Disclosure Letter sets forth a correct
and complete list of all of the material trade or service marks, registered
copyrights and all other material Intellectual Property (other than unregistered
copyrights) used or held for use in connection with, necessary for the conduct
of, or otherwise material to the business and operations of the MCM Companies
(the "MGI Intellectual Property") and sets forth the owner and nature of the
interest of the applicable MCM Company therein. All of the material copyrights
used or held for use in connection with, necessary for the conduct of, or
otherwise material to the business and operations of the MCM Companies have been
duly registered. Section 2.4.12(a) of the MGI Disclosure Letter sets forth a
correct and complete list of all material licenses, sublicenses or other similar
material agreements (including any amendments thereto) to which any MCM Company
is a party by which it is bound or under which it receives any benefits,
relating to any MGI Intellectual Property (the "MCM Licenses"). Each MCM License
is legal, valid, binding, in full force and effect and enforceable against the
MCM Company party thereto, and neither such MCM Company nor, to the knowledge of
MGI, any other party thereto is in breach or default in any material respect
under any MCM License and there exists no event or condition (including the
Transactions) which has resulted or would result in a material breach or default
thereunder upon the giving of notice, the passage of time or both. Except as set
forth in Section 2.4.12(a) of the MGI Disclosure 


                                       46
<PAGE>   223

Letter, the applicable MCM Company has and immediately after the Closing will
have the legal right to use the MGI Intellectual Property in connection with the
business as currently conducted or contemplated to be conducted by the MCM
Companies.

            (b) No Infringement, etc. Except as disclosed in Section 2.4.12(b)
of the MGI Disclosure Letter, the business and operations of the MCM Companies
as currently conducted do not infringe or otherwise conflict with any rights of
any Person in respect of any Intellectual Property, and none of the MCM
Companies has received notice or has actual knowledge of any such infringement
or conflict, except such infringements and conflicts as, individually and in the
aggregate, have not had and would not reasonably be expected to have an MGI
Material Adverse Effect. To the knowledge of MGI, none of the MGI Intellectual
Property owned by any MCM Company is being materially infringed or, other than
pursuant to license agreements in the ordinary course of business, otherwise
materially used or available for use by any Person other than the MCM Companies.
No MGI Intellectual Property owned by any MCM Company is subject to any
outstanding Order or agreement restricting the use thereof by any MCM Company
with respect to its business or restricting the licensing thereof by the MCM
Companies to any Person. Each trademark, trade dress or service mark and any
registration or application therefor, mask work, copyright registration or
application therefor included in any MGI Intellectual Property owned by any MCM
Company is in proper form and has been properly maintained in all material
respects and has otherwise been duly registered with, filed in or issued by, as
the case may be, the United States Patent and Trademark Office, the United
States Copyright Office or such other applicable filing offices, domestic or
foreign, and the applicable MCM Company has taken reasonable actions to ensure
protection under any applicable laws, and such registrations, filings, issuances
and other actions remain in full force and effect. Except as set forth in
Section 2.4.12(b) of the MGI Disclosure Letter, none of the MCM Companies has
entered into any agreement to indemnify any other Person against any charge of
infringement, dilution or violation of Intellectual Property rights, other than
pursuant to any such agreements entered into in connection with the use of
commercially available information systems applications.

            2.4.13. Insurance. Set forth in Section 2.4.13 of the MGI Disclosure
Letter is a complete and correct list of all of the insurance policies,
including, without limi-


                                       47
<PAGE>   224

tation, key man insurance policies, which are maintained for the benefit of any
MCM Company or with respect to the businesses conducted by the MCM Companies,
the MGI Assets or both, together with a description with respect to each policy
of the amount and types of coverage, limits and deductibles, inception and
expiration dates and insurance carrier. MGI has made available to the Founding
Stockholders and GS LP complete and correct copies of all such policies together
with all riders and amendments thereto. Such policies are in full force and
effect and all premiums due thereon have been paid. Such policies, with respect
to their amounts and types of coverage and limitations as to deductibles and
self-insured retentions, are, to the knowledge of MGI, adequate and customary to
insure against risks to which the MCM Companies or the MGI Assets are normally
exposed in the operation of the businesses conducted by the MCM Companies.

            2.4.14. Litigation. Except as set forth in Section 2.4.14 of the MGI
Disclosure Letter, there is no Litigation by or before any governmental or other
instrumentality or agency, pending (in the case of pending investigations only,
to the knowledge of MGI, and in the case of all other pending Litigation,
without regard to knowledge), or, to the knowledge of MGI, threatened, (i)
against or affecting the MCM Companies, the MGI Common Stock, the MGI Assets or
the businesses conducted by the MCM Companies, that would reasonably be expected
to result in liability on the part of the MCM Companies in an amount in excess
of $100,000 in the aggregate or (ii) seeking to prevent or challenging the
transactions contemplated by this Agreement. There are no outstanding Orders
issued by any federal, state or local governmental authority, agency, board,
commission, judicial, regulatory or administrative body, to which any MCM
Company is a party or against any MCM Company, or that, to the knowledge of MGI,
have or would reasonably be expected to have an MGI Material Adverse Effect.

            2.4.15. Compliance with Laws and Other Instruments. The MCM
Companies have at all times operated their respective businesses in compliance
with all laws, ordinances, rules and regulations (including all Environmental
Laws and the respective Organizational Documents of each of the MCM Companies)
and Orders applicable to any MCM Company, such business, any of the MGI Assets
or the use, ownership and operation thereof, except to the extent that failures
to be in such compliance would not, individually or in the aggregate, reasonably
be expected to 


                                       48
<PAGE>   225

result in an MGI Material Adverse Effect.

            2.4.16. Affiliate Relationships. Except as set forth in Section
2.4.16 of the MGI Disclosure Letter and other than the Fund IV Indemnification
Agreement, the CD&R Consulting Agreement and agreements listed in Section
2.4.11(d) of the MGI Disclosure Letter, none of the MCM Companies has entered
into any agreement, arrangement or other commitment or transaction with any
Affiliate (other than another MCM Company) which involved, during the
twelve-month period ended March 31, 1997 (or is reasonably expected, during the
calendar year ending December 31, 1998, to involve) payments or receipts in
excess of $25,000 in any individual case or, in the aggregate, $100,000.

            2.4.17. Information in Registration Statement and Offer Documents.
None of the information supplied by any MCM Company regarding any MCM Company
for inclusion or incorporation by reference in the Registration Statement or
Offer Documents will, in the case of the Registration Statement, at the date of
the effectiveness of the Registration Statement, and, in the case of the Offer
Documents, at the date such materials are mailed to the holders of MGI Common
Stock, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading.

            2.4.18. Employees, Labor Matters, etc. None of the MCM Companies is
a party to or bound by any collective bargaining or other labor agreement, and
there are no labor unions or similar organizations representing, or, to the
knowledge of MGI, purporting to represent or attempting to represent any
employees employed by any MCM Companies. Since June 30, 1994, there has not
occurred or, to the knowledge of MGI, been threatened any slowdown, work
stoppage, concerted refusal to work overtime or other similar labor activity
with respect to any employees of any MCM Company, in any such case, that has had
or would reasonably be expected to have or result in an MGI Material Adverse
Effect, or a material change in their relations with employees. There are no
material labor disputes currently subject to any grievance procedure,
arbitration or litigation and there is no representation petition pending or, to
the knowledge of MGI, threatened with respect to any employee of any MCM
Company. The MCM Companies have complied with all applicable laws pertaining to
the employment or termination of employment of their respective employees 


                                       49
<PAGE>   226

except for any failure so to comply that, individually and in the aggregate,
have not had and would not reasonably be expected to have or result in an MGI
Material Adverse Effect.

            2.4.19. ERISA. (a) Section 2.4.19(a) of the MGI Disclosure Letter
sets forth a complete and correct list of each "employee benefit plan," as such
term is defined in section 3(3) of ERISA, and each bonus, incentive or deferred
compensation, severance, termination, retention, change of control,
equity-based, performance or other employee or retiree benefit or compensation
plan, program, arrangement, agreement, policy or understanding, whether written
or unwritten, maintained, sponsored or contributed to or established by any MCM
Company or with respect to which any MCM Company is obligated to contribute or
is a party (collectively, the "MGI Plans"). With respect to each MGI Plan, MGI
has provided the Founding Stockholders and GS LP complete and correct copies of
(i) such MGI Plan, if written or a description of such MGI Plan if not written
and (ii) to the extent applicable to such MGI Plan, all trust agreements,
insurance contracts or other funding agreements or arrangements, the most recent
actuarial and trust reports, the most recent Form 5500 required to have been
filed with the IRS and all schedules thereto, the most recent IRS determination
letter, all current summary plan descriptions, and any and all amendments to any
such document.

            (b) Except as disclosed in Section 2.4.19(b) of the MGI Disclosure
Letter, each MGI Plan intended to be qualified under section 401(a) of the Code,
and the trust (if any) forming a part thereof, has received a favorable
determination letter from the IRS as to its qualification under the Code and to
the effect that each such trust is exempt from taxation under section 501(a) of
the Code, and nothing has occurred since the date of such determination letter
that could reasonably be expected to adversely affect such qualification or
tax-exempt status.

            (c) No MGI Plan is (i) subject to section 412 of the Code or section
302 or Title IV of ERISA, (ii) a "multiemployer plan" within the meaning of
section 4001(a) of ERISA or (iii) a "multiple employer plan" within the meaning
of section 4064 of ERISA.

            (d) None of the MCM Companies has incurred (either directly or
indirectly, including as a result of an indemnification obligation) any material
liability under or pursuant to Title I or IV of ERISA or the penalty, excise 


                                       50
<PAGE>   227

Tax or joint and several liability provisions of the Code relating to employee
benefit plans and, to the knowledge of MGI, no event, transaction or condition
has occurred or exists that could result in any such liability to any of the MCM
Companies or, following the Closing, the Parent or any of its Affiliates. All
contributions and premiums required to have been paid by any MCM Company to any
MGI Plan under the terms of any such MGI Plan or its related trust, insurance
contract or other funding arrangement, or pursuant to any applicable law
(including ERISA and the Code) or collective bargaining agreement have been paid
when due, and to the extent not yet due, have been properly and adequately
reflected on the MGI Financial Statements.

            (e) Each of the MGI Plans has been operated and administered in all
respects in compliance with its terms and all applicable laws except for any
failure so to comply that, individually and in the aggregate, has not had and
would not reasonably be expected to have or result in an MGI Material Adverse
Effect. There are no material pending or, to the knowledge of MGI, threatened
claims by or on behalf of any of the MGI Plans, by any current or former
director, officer or employee of any MCM Company or otherwise involving any such
MGI Plan or the assets of any MGI Plan (other than routine claims for benefits,
all of which have been fully reserved for on the MGI Financial Statements).

            (f) The consummation of the transactions contemplated by this
Agreement will not result in an increase in the amount of compensation or
benefits or the acceleration of the vesting or timing of payment of any
compensation or benefits payable to or in respect of or accrued on behalf of any
current or former director, officer or employee of MGI or entitle any such

or another date prior to the Closing Date shall be determined solely as of the
date hereof or such other date, as the case may be. MGI, the Parent and Merger
Sub shall have duly performed and complied in all material respects with all
agreements and conditions required by this Agreement to be performed or complied
with by them prior to or on the Closing Date.

resulted in, or would be reasonably likely to have or result in, an MGI Material
Adverse Effect.

and performance of this Agreement or the consummation of the transactions
contemplated hereby listed in Section 2.4.2 of the MGI Disclosure Letter, except

individually and in the aggregate, would not have an MGI Material Adverse Effect
and would not adversely affect the ability of MGI to perform its obligations
hereunder.

                                OTHER AGREEMENTS

            5.1 Noncompetition. Each of Daniel H. Yergin, James P. Rosenfield
and Joseph A. Stanislaw (collectively, the "Founding Stockholders") hereby
agrees that during the period commencing on the Closing Date and ending on the
fourth anniversary of the Closing Date, he shall not, directly or indirectly,
(A) as an individual proprietor, partner, member, principal, officer, employee,
agent, consultant or stockholder, develop, produce, market, sell or render (or
assist any other person in developing, producing, marketing, selling or
rendering) products or services competitive anywhere in the United States or
elsewhere in the world with, or (B) engage in business with, serve as an agent
or consultant to, or become an individual proprietor, partner, member, principal
or stockholder (other than a holder of less than 1% of the outstanding voting
shares of any publicly held company) of or become employed in an executive
capacity by, any person, firm or other entity ("Competitor") a substantial
portion of whose business competes anywhere in the United States or elsewhere in
the world with a substantial portion of the business of the Parent, CERA Inc.,
MGI or any of their respective Subsidiaries (collectively, the "MGI/CERA Group")
that relates to the financial information, financial analysis, energy
information and analysis or any other business then engaged in by any member of
the MGI/CERA Group; provided that this Section 5.1 shall not be deemed to
prohibit any of the Founding Stockholders from teaching courses at educational
institutions or writing books or articles for public sale or making appearances
on television or preparing or otherwise participating in television programs;
and provided, further, that if the employment of a Founding Stockholder with
CERA Inc. shall be terminated after the Closing Without Cause (as such term
shall be defined in the applicable Employment Agreement between CERA Inc. and
such Founding Stockholder) or for Good Reason (also as shall be defined in such
Employment Agreement), the noncompetition period set forth in this Section 5.1
shall terminate with respect to such Founding Stockholder on the earlier of (x)
the fourth anniversary of the Closing Date and (y) the first anniversary of the
date of termination of such Founding Stockholder's employment. For the purposes
of this Section 5.1, a "substantial portion" (x) in the case of the business of
Competitor shall mean a line or lines of business that account for more than 50%
of the consolidated revenue of Competitor 


                                       76
<PAGE>   253

and (y) in the case of the MGI/CERA Group shall mean a line or lines of business
that account for more than 25% of the consolidated revenues of the MGI/CERA
Group, in each case for the fiscal year ended immediately prior to the date on
which the Founding Stockholder first proposes to engage in any of the activities
described in clause (B) of the immediately preceding sentence, provided,
however, that in the case of a Competitor that has had less than three full
years of operations, "substantial portion" shall mean a line or lines of
business accounting for more than 50% of the projected consolidated revenues of
such Competitor for the two fiscal years next succeeding the date on which
Founding Stockholder first proposes to engage in any of the activities described
in clause (B) of the immediately preceding sentence. Whether any such person,
firm or entity so competes shall be determined in good faith by Employer's Board
(as such term is defined in the applicable Employment Agreement). For purposes
of this Section 5.1, the phrase employment "in an executive capacity" shall mean
employment in any position in connection with which the applicable Founding
Stockholder has or reasonably would be viewed as having powers and authorities
with respect to any other person, firm or other entity or any part of the
business thereof that are substantially similar, with respect thereto, to the
powers and authorities assigned to any executive officer of CERA Inc. as
described in the By-Laws of CERA Inc. as in effect on the date hereof.

            5.2 Enforceability of Covenants. The provisions of Sections 3.4.1
and 5.1 were negotiated in good faith by the parties hereto, and the parties
hereto agree that such provisions are reasonable and are not more restrictive
than necessary to protect the legitimate interests of the parties hereto. If any
provision contained in Section 3.4.1 or Section 5.1 shall for any reason be held
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision of Section 3.4.1 or
Section 5.1. It is the intention of the parties hereto that if any of the
restrictions or covenants contained herein is held to cover a geographic area or
to be for a length of time that is not permitted by applicable law, or is any
way construed to be too broad or to any extent invalid, such provision shall not
be construed to be null, void and of no effect, but to the extent such provision
would be valid or enforceable under applicable law, a court of competent
jurisdiction shall construe and interpret or reform such provision to provide
for a restriction or covenant having the maximum enforceable geographic area,
time period and other provisions (not greater than those 


                                       77
<PAGE>   254

contained herein) as shall be valid and enforceable under applicable law.

            5.3 Further Actions and Events. In connection with the Closing:

Closing:

            (a) CERA Stock Restriction Agreements. Each of the Stockholders

restriction agreements and documents listed in Section 2.1.2(c) of the CERA
Disclosure Letter, including, without limitation, the Cambridge Energy Research
Associates, Inc. 1985 Restricted Stock Plan, as amended, shall terminate and
have no further force or effect (except to the extent that any provision thereof
shall expressly provide that such provision shall survive the termination of
such agreement or document), and that from and after the Closing, all of the
parties thereto shall be released from all of their liabilities and obligations
thereunder (other than any such liabilities or obligations that arose prior to
the Closing).

            (b) Existing Arrangements with GS LP. Each of the Stockholders and
GS LP hereby agrees that, effective simultaneously with the Closing, each of the

and instruments executed or delivered in connection with the acquisition by GS
LP of the GS Partnership Interest (other than the Existing Partnership
Agreement, which shall be terminated by operation of law, and the GS Advisory
Agreement) shall terminate and have no further force or effect (except to the
extent that any provision thereof shall expressly provide that such provision
shall survive the termination of such agreement or document), and that from and
after the Closing, all of the parties thereto shall be released from all of
their liabilities and obligations thereunder (other than any such liabilities or
obligations that arose prior to the Closing).

            (c) MGI and CERA LLC Unit Option Plans. MGI shall, and each of the
Stockholders shall cause CERA Inc. to, adopt the MCM Group, Inc. Management LLC

            (d) CERA Inc. Bonus Plan. Each of the Stockholders shall cause CERA
Inc. to adopt a performance bonus program (the "CERA Bonus Plan"), in form and
substance mutually satisfactory to MGI and the Founding Stockholders, pursuant
to which the participants in the CERA Bonus Plan shall be entitled to receive
annual incentive awards based upon the annual operating targets and other
performance goals established, pursuant to the CERA Bonus Plan, by CERA Inc.'s
board of directors from time to time.

            5.4 Certain Payments to CERA Management Members. The Parent hereby
agrees to cause CERA Inc. to pay to each CERA Management Member who shall have
received LLC Units pursuant to the distribution to CERA Management Members

after the due date (after taking into account any applicable extension) for
filing the U.S. federal Income Tax Return of CERA Inc. for each taxable year
ending after the Closing Date during which any deduction with respect to such
distribution is actually utilized by CERA Inc. for U.S. federal Income Tax
purposes (whether as a current deduction or as a deduction for a net operating
loss carryover resulting from any such deduction), cash (subject to applicable
withholding) in an amount equal to the product of (i) the quotient of (x) the
number of LLC Units received by such CERA Management Member pursuant to such
distribution divided by (y) the total number of LLC Units distributed by CERA
Inc. pursuant to such distribution and (ii) an amount equal to (x) the amount of
any such deduction so utilized by CERA Inc. during such taxable year (in the
case of any such loss carryover, net of any related gain included in the gross
income of CERA Inc. as a result of any examination of any U.S. federal Income
Tax Return of CERA Inc. for any such taxable year prior to such taxable year)
multiplied by (y) the highest corporate tax rate applicable for U.S. federal
Income Tax purposes for such taxable year, provided that the amount set forth in
subclause (ii)(x) shall not exceed CERA Inc.'s taxable income for such taxable
year after taking into account all available deductions, losses and net
operating loss carryovers but before taking into account the deduction described
in subclause (ii)(x).

            5.5 Grants of Options to Purchase LLC Units. (i) On the Closing
Date, (a) MGI shall grant options to purchase an aggregate of 33,444 LLC Units

                                   TERMINATION

            6.1 Termination. This Agreement may be terminated at any time prior
to the Closing Date:

            (a) by the written agreement of the Founding Stockholders and MGI;

            (b) by MGI, on the one hand, or the Founding Stockholders, on the
      other hand, by written notice to the other after 5:00 p.m., New York City
      time, on November 30, 1997 if the Closing Date shall not have occurred by
      such date (unless the failure of the Closing Date to occur shall be due
      to, in the case of any termination by MGI, any material breach of this
      Agreement by MGI, the Parent or Merger Sub or, in the case of any
      termination by the Founding Stockholders, any material breach of this
      Agreement by the Stockholders or GS LP), unless such date is extended by
      the mutual written consent of MGI and the Founding Stockholders;

            (c) by MGI if there has been a breach on the part of the
      Stockholders or GS LP of any of their covenants set forth herein, or any
      failure on the part of the Stockholders or GS LP to perform their
      obligations hereunder (provided that MGI, the Parent and Merger Sub shall
      have performed and complied with, in all material respects, all agreements
      and covenants required by this Agreement to have been performed or
      complied with by them) prior to such time, such that, in any such case,
      any of the conditions to the effectiveness of the Transactions set forth
      in Section 4.1 or 4.2 could not 


                                       80
<PAGE>   257

      (including without limitation through the use of diligent efforts to cure
      such breach or failure) be satisfied on or prior to the termination date
      contemplated by Section 6.1(b); or

            (d) by any of the Founding Stockholders, if there has been a breach
      on the part of MGI, the Parent or Merger Sub of any of their covenants set
      forth herein, or any failure on the part of MGI, the Parent or Merger Sub
      to perform their obligations hereunder (provided that the Stockholders and
      GS LP shall have performed and complied with, in all material respects,
      all agreements and covenants required by this Agreement to have been
      performed or complied with by them) prior to such time, such that, in any
      such case, any of the conditions to the effectiveness of the Transactions
      set forth in Section 4.1 or 4.3 could not (including without limitation
      through the use of diligent efforts to cure such breach or failure) be
      satisfied on or prior to the termination date contemplated by Section
      6.1(b).

            6.2 Effect of Termination. In the event of the termination of this
Agreement pursuant to Section 6.1, this Agreement shall become void and have no
effect, without any liability to any Person in respect hereof or of the
transactions contemplated hereby on the part of any party hereto, or any of its
directors, officers, employees, agents, consultants, representatives, advisers,
stockholders, partners or Affiliates, except for any liability resulting from
any party's breach of this Agreement and except that the provisions of Sections
3.4.1(b) and (c), 8.2, 8.5.4, 8.5.7 and 8.5.8 shall survive any such
termination.

                                   ARTICLE VII

                                 INDEMNIFICATION

            7.1 Indemnification by the Stockholders and GS LP. To the fullest
extent permitted by applicable law, each of the Stockholders, severally and not
jointly, and GS LP covenants and agrees to defend, indemnify and hold harmless
each of the Parent, the Surviving Corporation, such of the other members of the
MCM Group (without duplication) as are, directly or indirectly, wholly owned by
the Parent and the respective officers, directors and employees of the Parent,
the Surviving Corporation and any such other member of the


                                       81
<PAGE>   258

MCM Group (collectively, the "MGI Indemnitees") from and against, and pay or
reimburse the MGI Indemnitees for, any and all claims, demands, liabilities,
obligations, losses, fines, costs, expenses, Litigation, deficiencies or damages
(whether absolute, accrued, conditional or otherwise and whether or not
resulting from third party claims), including interest and penalties with
respect thereto and out-of-pocket expenses and reasonable attorneys' and
accountants' fees and expenses incurred in the investigation or defense of any
of the same or in asserting, preserving or enforcing any of their respective
rights hereunder (collectively, "Losses"), incurred or suffered by any MGI
Indemnitee (provided that any Loss incurred or suffered by any member of the MCM
Group that is not, directly or indirectly, wholly owned by the Parent shall be
deemed to be a Loss incurred or suffered by the Parent in an amount equal to the
amount of such Loss incurred or suffered by such member of the MCM Group
multiplied by a fraction, the numerator of which shall be the portion of the
outstanding common equity interests of such member of the MCM Group that,
directly or indirectly, is held by any wholly owned member of the MCM Group and
the denominator of which shall be all of the outstanding common equity interests
of such non-wholly owned member of the MCM Group) with respect to, resulting
from or arising out of:

            (a) any inaccuracy of any representation or warranty by the
      Stockholders or GS LP made in or pursuant to this Agreement or in any
      certificate delivered by any Stockholder or GS LP in connection with the
      Closing; or

            (b) any failure by any of the Stockholders or GS LP to perform any
      of their covenants or agreements hereunder or fulfill any other of their
      obligations in respect hereof;

provided, that (i) in the case of any representation and warranty set forth in
Section 2.1, GS LP shall indemnify and hold harmless under this Section 7.1 for
only 10%, and each of the Stockholders shall indemnify and hold harmless under
this Section 7.1 for their respective percentages (as calculated pursuant to
Section 7.4(b)) of 90%, of each Loss incurred or suffered with respect to,
resulting from or arising out of such representation and warranty; (ii) GS LP
shall not indemnify and hold harmless under this Section 7.1 for Losses incurred
or suffered with respect to, resulting from or arising out of any representation
and warranty set forth in Section 2.2 or any breach or nonfulfillment by the
Stockholders of any covenant, agreement or obligation 


                                       82
<PAGE>   259

described in Section 7.1(b); and (iii) the Stockholders shall not indemnify and
hold harmless under this Section 7.1 for Losses incurred or suffered with
respect to, resulting from or arising out of any representation and warranty set
forth in Section 2.3 or any breach or nonfulfillment by GS LP of any covenant,
agreement or obligation described in Section 7.1(b).

            7.2 Indemnification by MGI. To the fullest extent permitted by
applicable law, MGI covenants and agrees to defend, indemnify and hold harmless
each of the Stockholders and GS LP from and against, and pay or reimburse them
for, any and all Losses incurred or suffered by any of them with respect to,
resulting from or arising out of:

            (a) any inaccuracy of any representation or warranty by MGI, the
      Parent or Merger Sub made in or pursuant to this Agreement or in any
      certificate delivered by MGI, the Parent or Merger Sub in connection with
      the Closing; or

            (b) any failure by MGI, the Parent or Merger Sub to perform any of
      their covenants or agreements hereunder or fulfill any other of their
      obligations in respect hereof.

            7.3 Further Indemnification by GS LP. GS LP covenants and agrees to
defend, indemnify and hold harmless each of the Stockholders from and against,
and pay or reimburse them for, any and all Losses incurred or suffered by any of
them with respect to, resulting from or arising out of:

            (a) any inaccuracy of any representation or warranty by GS LP made
      in or pursuant to Section 2.3 of this Agreement or in any certificate
      delivered by GS LP in connection with the Closing relating to any such
      representation or warranty; or

            (b) any failure by GS LP to perform any of its covenants or
      agreements hereunder or fulfill any of its obligations in respect hereof.

            7.4 Payment Adjustments, etc. Any indemnity payment made by any
Stockholder or GS LP to the MGI Indemnitees, on the one hand, or by MGI to the
Stockholders or GS LP, on the other hand, pursuant to this Article VII in
respect of any claim (i) shall be net of an amount equal to 


                                       83
<PAGE>   260

(x) any insurance proceeds realized by and paid to the Indemnified Party minus
(y) any related costs and expenses, including the aggregate cost of pursuing any
related insurance claims plus any correspondent increases in insurance premiums
or other chargebacks and (ii) shall be (a) reduced by an amount equal to the
Income Tax benefits, if any, attributable to such claim and (b) increased by an
amount equal to the Income Taxes, if any, attributable to the receipt of such
indemnity payment, but only to the extent that such Tax benefits are actually
realized, or such Income Taxes are actually paid, as the case may be, by the
Indemnified Party or any consolidated, combined or unitary group of which any
Indemnified Party is a member.

            7.5 Indemnification Procedures; Limitations. (a) In the case of any
claim asserted by a third party against a party entitled to indemnification
under this Article VII (the "Indemnified Party"), notice shall be given by the
Indemnified Party to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual knowledge
of any claim as to which indemnity may be sought, and the Indemnified Party
shall permit the Indemnifying Party (at the expense of such Indemnifying Party)
to assume the defense of any claim or any litigation resulting therefrom,
provided, that (i) counsel for the Indemnifying Party who shall conduct the
defense of such claim or litigation shall be reasonably satisfactory to the
Indemnified Party, and the Indemnified Party may participate in such defense at
such Indemnified Party's expense and (ii) the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its indemnification obligation under this Agreement except to the extent that
such failure results in a lack of actual notice to the Indemnifying Party and
such Indemnifying Party is materially prejudiced as a result of such failure to
give notice. Except with the prior written consent of the Indemnified Party, no
Indemnifying Party, in the defense of any such claim or litigation, shall
consent to entry of any judgment or enter into any settlement that provides for
injunctive or other non-monetary relief affecting the Indemnified Party or that
does not include as an unconditional term thereof the giving by each claimant or
plaintiff to such Indemnified Party of a release from all liability with respect
to such claim or litigation. In the event that the Indemnified Party shall in
good faith determine that the conduct of the defense of any claim subject to
indemnification hereunder or any proposed settlement of any such claim by the
Indemnifying Party might be expected to affect adversely the Indemnified 


                                       84
<PAGE>   261

Party's Tax liability or (in the case of an Indemnified Party that is an MGI
Indemnitee) the ability of any member of the MCM Group to conduct, in any
material respect, its business, or that the Indemnified Party may have available
to it one or more defenses or counterclaims that are inconsistent with one or
more of those that may be available to the Indemnifying Party in respect of such
claim or any litigation relating thereto, the Indemnified Party shall have the
right at all times to participate in the defense, settlement, negotiations or
litigation relating to any such claim with counsel of its own choosing, with all
of the fees and expenses of one (but not more than one) such counsel payable by
the Indemnifying Party, provided that if the Indemnified Party does so exercise
its right to participate, the Indemnified Party shall not settle such claim or
litigation without the written consent of the Indemnifying Party, such consent
not to be unreasonably withheld. In the event that the Indemnifying Party does
not accept the defense of any matter as above provided, the Indemnified Party
shall have the full right to defend against any such claim or demand, and shall
be entitled to settle or agree to pay in full such claim or demand.

            (b) Notwithstanding anything to the contrary in the foregoing, (i)
the aggregate indemnification obligations hereunder of the Stockholders and GS
LP for Losses with respect to, resulting from or arising out of Section 7.1(a)
and (b) shall not exceed $5,000,000 and (ii) each of the Stockholders and GS LP
shall be required to indemnify and hold harmless under Section 7.1(a) and (b)
(x) only for each claim in respect of which the aggregate Losses exceed $50,000
and (y) only to the extent that the aggregate amount (without duplication and
without regard to the indemnification threshold set forth in clause (x) above)
of Losses incurred or suffered with respect to or in connection with the matters
described in such Sections exceeds $250,000. For purposes of calculating the
percentage of any Losses that any Stockholder shall be responsible for, the
percentage shall be based on the ratio on the date hereof of (i) the number of
shares of CERA Common Stock owned by such Stockholder to (ii) the aggregate
number of shares of CERA Common Stock owned by all the Stockholders; provided
that in the event that any Stockholder that is a trust for the benefit of any
other Stockholder and/or the family members of or other persons affiliated with
such other Stockholder shall fail to pay any or all of its pro rata portion of
any Losses of an Indemnified Party subject to indemnification under Section 7.1
promptly after a request therefor is made, such Indemnified Party shall be
entitled to recover, without 


                                       85
<PAGE>   262

duplication, the amount of such unpaid Losses in accordance with the provisions
hereof directly from such other Stockholder (in addition to any other payment in
respect of such Losses that may be due hereunder from such other Stockholder).

and to take all such actions as it deems necessary or appropriate to accomplish

for purposes of the Delaware Act. Subject to this Section 5.1(b), the number of
Directors may be modified from time to time by resolution of the Board. Each
Director shall hold office until a successor is elected as provided herein or
until such Director's earlier death, resignation or removal. Except as otherwise
provided in this Section 5.1(b), at each meeting of the Members for the election
of Directors, provided a quorum is present, the Directors shall be elected by a
majority of the votes validly cast in such election. If any vacancies shall
occur in the Board, by reason of death, resignation, removal or otherwise, the
Directors then in office shall continue to act, and such vacancies may be filled
by the Members, subject to the provisions of paragraph (b)(ii) of this Section
5.1, or, following the settlement date of the first Underwritten Public Offering
after the date hereof, by a majority vote of the Directors then in office (even
if less than a quorum). If the authorized number of Directors shall be
increased, newly created directorships may be elected at a meeting of the
Members, subject to this Section 5.1(b).

            Directors need not be Members. Each of the Members agrees that such
Member will, at all times after the date of this Agreement and until the
settlement date of the first Underwritten Public Offering after the date hereof,
vote all LLC Units now or hereafter owned by such Member at any meeting of
Members and in whatever other manner is necessary to ensure that (x) the Board

affiliated with CD&R, Fund IV, Brera or any of the CERA Principals, as may be
nominated by Fund IV with the written consent of the Consenting CERA Principal,
whose consent shall not be unreasonably withheld (the "Independent Nominees"
and, together with the CERA Nominees, the MCM Nominee, the CEO Nominee and the
Fund IV Nominees, the "Nominees") and (y) all such Nominees shall be duly
elected. Of the Directors on the date hereof, Messrs. Yergin and _______ shall
be the CERA Nominees, Mr. David D. Nixon shall be the MCM Nominee, Messrs.

            (ii) Replacement Nominees. If, prior to his or her election to the
Board pursuant to Section 5.1(b)(i), any Nominee shall be unable or unwilling to
serve as a Director, the Member or Members who nominated such Nominee in
accordance with Section 5.1(b)(i) or, following the settlement date of the first
Underwritten Public Offering after the date hereof, the Board shall be entitled
to nominate a replacement who shall then be a Nominee for purposes of this
Section 5.1. If, following election to the Board pursuant to Section 5.1(b)(i),
any Nominee shall resign or be removed or be unable to serve for any reason
prior to the expiration of his or her term as a Director (a "Withdrawing
Director"), the Member or Members who nominated such Withdrawing Director shall
appoint a replacement Nominee (a "Substitute Director") to fill the unexpired
term of the Withdrawing Director whom such Substitute Director is replacing,
provided that any Independent Nominee shall be replaced with the written consent
of the Consenting CERA Principal, whose consent shall not be unreasonably
withheld. If a Member or Members shall fail to so appoint a Substitute Director
in the manner provided above, the seat of such Substitute Director shall remain
vacant. Notwithstanding the preceding sentences of this paragraph (ii), if,
following the settlement date of the first Underwritten Public Offering after
the date hereof, any vacancies shall occur in the Board or if the authorized
number of Directors shall be increased, the Directors then in office shall
continue to act, and such vacancies and newly created directorships may be
filled by a majority of the Directors then in office, although less than a
quorum, and any such vacancy or newly created directorship may also be filled at
any time by vote of the Members.

            (iii) Removal. Members shall have the right to remove any Director
at any time for cause upon the affirmative vote of the holders of a majority of
outstanding LLC Units entitled to vote for the election of such Director. The
Member or Members that nominate any Director pursuant to Section 5.1(b) or,
following the settlement date of the first Underwritten Public Offering after
the date hereof, the holders of a majority of the outstanding LLC Units entitled
to vote for the election of Directors shall have the right to remove such
Director at any time, with or without cause, by delivery of written notice to
the Board or by action taken at any meeting of Members, and shall, upon any such
removal, appoint a Substitute Director, in accordance with Section 5.1(b)(ii). A
majority of the Directors then in office shall have the right to remove a
Director for cause. Upon taking such action, the Director shall cease to be a
Director. In the event that a Director is removed by the Board for cause, until
the settlement date of the first Underwritten Public Offering after the date
hereof, only the Member or Members who nominated or appointed such removed
Director shall be entitled to appoint his replacement. Until the settlement date
of the first Underwritten Public Offering after the date hereof, no Director
shall be removed without cause without the consent of the Member or Members that
nominated or appointed such Director.

            (b) the existence or non-existence of any fact or facts which
      constitute a condition precedent to acts by the Chief Executive Officer,
      the President or in any other manner germane to the affairs of the
      Company;

            (c) the Persons who are authorized to execute and deliver any
      instrument or document of or on behalf of the Company; or

            (d) any act or failure to act by the Company or as to any other
      matter whatsoever involving the Company or any Member.

                                  ARTICLE VIII

                       CAPITAL CONTRIBUTIONS AND INTERESTS

            Section 8.1. Capital Units. The limited liability company interests
of the Company shall be represented by two classes of units of capital of the
Company, which shall consist of voting limited liability company interests
("Voting LLC Units") and non-voting limited liability company interests
("Non-Voting LLC Units" and, together with Voting LLC Units, the "LLC Units").
The Company shall have authority to issue (a) LLC Units to the Members (other
than the CERA Management Members) listed on Schedule A hereto, in the amounts
set forth thereon, and to CERA Inc. for transfer to the CERA Management Members,
in accordance with Section 2.1(b), (b) the Contingent LLC Units, (c) the LLC
Units issuable upon the exercise of CERA Contingent Options and GS Contingent
Options, (d) the LLC Units to be transferred upon the exercise of Existing MGI
Options and MGI/CERA Additional Options and (e) such additional LLC Units as may
be authorized from time to time by the Board.

            Section 8.2. Capital Contributions of Property. On the Closing Date,
each Member listed on Schedule A hereto other than the CERA Management Members
shall be deemed to have contributed to the capital of the Company property
having the value set forth opposite such Member's name as such Member's capital
contribution on Schedule A hereto. Any contributions of property after the
Closing Date (including contributions in exchange for the issuance of LLC Units
by the Company) shall have the value determined by the Board.


                                       42
<PAGE>   334

            Section 8.3. Additional Capital Contributions. No Member shall be
required to make any additional capital contribution to the Company in respect
of the LLC Units then owned by such Member. However, a Member may make such
additional capital contributions to the Company, but only with the written
consent of the Board. The provisions of this Section 8.3 are intended solely to
benefit the Members and, to the fullest extent permitted by applicable law,
shall not be construed as conferring any benefit upon any creditor of the
Company (and no such creditor shall be a third party beneficiary of this
Agreement), and no Member shall have any duty or obligation to any creditor of
the Company to make any additional capital contributions or to cause the Board
to consent to the making of additional capital contributions. Members shall be
deemed to have contributed such additional capital upon issuance of additional
LLC Units equal to the cash purchase price for such LLC Units or, if no cash is
paid or there is non-cash consideration, in the amount of the fair market value
of such non-cash consideration as determined by the Board in good faith at or
prior to issuance of such LLC Units.

            Section 8.4. Member's Interest. A Member's LLC Units shall for all
purposes be personal property. A Member has no interest in specific Company
property.

            Section 8.5. Certificates of LLC Units. The LLC Units shall be
represented by certificates, provided that the Board may provide by resolution
or resolutions that some or all of any or all classes or groups of the LLC Units
shall be uncertificated LLC Units. Any such resolution shall not apply to LLC
Units represented by a certificate until such certificate is surrendered to the
Company. Notwithstanding the adoption of such a resolution by the Board, upon
request a holder of uncertificated LLC Units shall be entitled to have a
certificate signed by or in the name of the Company, by the Chief Executive
Officer or a Vice President, and by the Treasurer, an Assistant Treasurer, the
Secretary or an Assistant Secretary, representing the number of LLC Units held
by such holder. Such certificate shall be in such form as the Board may
determine, to the extent consistent with applicable law, the Certificate and
this Agreement.

            Section 8.6. Issuance of Non-Voting LLC Units. The Company shall not
issue or sell any Non-Voting LLC Units except in connection with an exchange of
Voting LLC Units as provided in Section 8.7.

            Section 8.7. Conversion and Exchange. (a) Special Exchange of Voting
LLC Units for Non-Voting LLC Units. Voting LLC Units held by Fund IV may be
exchanged for the same number of Non-Voting LLC Units for the sole purpose of a
distribution by Fund IV to one or more of its limited partners which is a


                                       43
<PAGE>   335

Regulated Holder, provided that the number of Voting LLC Units so exchanged does
not exceed the number of Regulated Securities required for any such Regulated
Holder. The subsequent transfer of any Non-Voting LLC Units by any such
Regulated Holder shall be subject to the provisions of Section 8.7(b)(ii), and
such Regulated Holder shall be permitted to convert Non-Voting LLC Units into
Voting LLC Units to the extent set forth in Section 8.7(b)(i).

            (b) Conversion of Non-Voting LLC Units into Voting LLC Units. (i)
Optional Conversion of Non-Voting LLC Units. Each record holder of Non-Voting
LLC Units shall be entitled to convert any or all of such holder's Non-Voting
LLC Units into the same number of Voting LLC Units, provided that no holder of
Non-Voting LLC Units shall be entitled to convert any Non-Voting LLC Units to
the extent that, as a result of such conversion, such holder or the Affiliates
thereof would directly or indirectly own, control or have power to vote a
greater quantity of securities of any kind issued by the Company than such
holder and the Affiliates thereof permitted to own, control or have power to
vote under any law, regulation, order, rule or other requirement of any
governmental authority at any time applicable to such holder and the Affiliates
thereof.

            (ii) Automatic Conversion of Non-Voting LLC Units. Upon the sale or
transfer of any Non-Voting LLC Units by the holder thereof to any Person who is
not an Affiliate of such holder (but including, without limitation, any sale or
transfer to an underwriter in connection with a Public Offering of Voting LLC
Units regardless of whether such underwriter is an Affiliate of such holder),
such Non-Voting LLC Units shall automatically be converted without further
action (an "Automatic Conversion") into an equal number of Voting LLC Units,
provided that a distribution of Non-Voting LLC Units by Fund IV to a Regulated
Holder shall not result in an Automatic Conversion.

            Section 8.8. Certain Conversion and Exchange Procedures. (a) Each
conversion of Non-Voting LLC Units into Voting LLC Units (other than an
Automatic Conversion contemplated by Section 8.7(b)(ii)) and each exchange of
Voting LLC Units for Non-Voting LLC Units will be effected by the surrender of
the certificate or certificates representing the LLC Units to be converted or
exchanged, as the case may be, at the principal office of the Company or the
transfer agent designated by the Company, if any, at any time during normal
business hours, together with a written notice by the holder of such LLC Units
stating either (i) the number of Non-Voting LLC Units that such holder desires
to convert into Voting LLC Units (and such statement will obligate the Company
to issue such Voting LLC Units), or (ii) the number of Voting LLC Units that
such holder desires to exchange for Non-Voting LLC Units and that such exchange
is required in order for such holder to make a 


                                       44
<PAGE>   336

distribution of LLC Units to a proposed distributee that is a Regulated Holder
(and such statement will obligate the Company to issue such Non-Voting LLC
Units). Such conversion or exchange will be deemed to have been effected as of
the close of business on the date on which such certificate or certificates have
been surrendered and such notice has been received, and at such time the rights
of any such holder with respect to the converted Non-Voting LLC Units or
exchanged Voting LLC Units, as the case may be, will cease and the person or
persons in whose name or names the certificate or certificates for Voting LLC
Units or Non-Voting LLC Units, as the case may be, are to be issued upon such
conversion or exchange will be deemed to have become the holder or holders of
record of the Voting LLC Units or Non-Voting LLC Units, as the case may be,
represented thereby.

            (b) Promptly after such surrender and the receipt of the written
notice referred to in Section 8.8(a), the Company will issue and deliver in
accordance with the surrendering holder's instructions the certificate or
certificates for the Voting LLC Units or Non-Voting LLC Units, as the case may
be, issuable upon such conversion or exchange and a certificate representing any
Voting LLC Units or Non-Voting LLC Units, as the case may be, which was
represented by the certificate or certificates delivered to the Company in
connection with such conversion or exchange but which was not converted or
exchanged. The Company shall be entitled to rely upon any written notice
delivered pursuant to Section 8.8(a) and such notice shall, in the absence of
manifest error, be binding and conclusive upon the Company.

            (c) From and after an Automatic Conversion pursuant to Section
8.7(b)(ii), (i) each certificate formerly representing Non-Voting LLC Units
which NonVoting LLC Units were held by the holder thereof or any Affiliate
thereof and which were converted pursuant to such Automatic Conversion shall
thereafter be deemed to represent (A) only the like number of Voting LLC Units
into which such Non-Voting LLC Units have been converted pursuant to such
Automatic Conversion (and no Person shall thereafter have any rights in respect
of such Non-Voting LLC Units), plus (B) if all the Non-Voting LLC Units
represented by such certificate were not converted pursuant to such Automatic
Conversion, such number of Non-Voting LLC Units which were not so converted and
(ii) upon any surrender for transfer of any such certificate accompanied by a
written notice certifying that an Automatic Conversion has occurred and
specifying the number of LLC Units so converted, the Company will issue and
deliver (A) a certificate or certificates representing the Voting LLC Units into
which such Non-Voting LLC Units have been converted pursuant to such Automatic
Conversion and (B) if all the Non-Voting LLC Units represented by such
certificate or certificates were not converted pursuant to such Automatic
Conversion, a certificate or certificates representing such number of Non-Voting
LLC Units which were not so converted. The Company shall be entitled to rely on
any written notice 


                                       45
<PAGE>   337

delivered to the effect that an Automatic Conversion has occurred and such
notice shall, in the absence of manifest error, be binding and conclusive upon
the Company.

            Section 8.9. Signatures; Facsimile. Any or all of such signatures on
the certificate representing LLC Units may be a facsimile, engraved or printed,
to the extent permitted by law. In case any Officer, transfer or exchange agent
or registrar who has signed, or whose facsimile signature has been placed upon,
such a certificate shall have ceased to be such officer, transfer or exchange
agent or registrar before such certificate is issued, it may be issued by the
Company with the same effect as if he were such Officer, transfer agent or
registrar at the date of issue.

            Section 8.10. Lost, Stolen or Destroyed Certificates. The Board may
direct that a new certificate representing LLC Units be issued in place of any
certificate theretofore issued by the Company alleged to have been lost, stolen
or destroyed, upon delivery to the Board of an affidavit of the owner or owners
of such certificate, setting forth such allegation. The Board may require the
owner of such lost, stolen or destroyed certificate, or his legal
representative, to give the Company a bond sufficient to indemnify it against
any claim that may be made against it on account of the alleged loss, theft or
destruction of any such certificate or the issuance of any such new certificate.

            Section 8.11. Registration and Transfer of LLC Units. Upon surrender
to the Company or the transfer agent of the Company, if any, of a certificate
for LLC Units, duly endorsed or accompanied by appropriate evidence of
succession, assignment or authority to transfer, in compliance with the
provisions hereof, the Company shall issue a new certificate representing LLC
Units to the person entitled thereto, cancel the old certificate and record the
transaction upon its books. Subject to the provisions of the Certificate and
this Agreement, the Board may prescribe such additional rules and regulations as
it may deem appropriate relating to the issue, transfer and registration of LLC
Units.

            Section 8.12. Transfer Agent, Exchange Agent and Registrar. The
Board may appoint one or more transfer agents, one or more exchange agents and
one or more registrars, and may require all certificates representing LLC Units
to bear the signature of any such transfer agents, exchange agents or
registrars.

                                   ARTICLE IX

                           ALLOCATIONS; DISTRIBUTIONS

            Section 9.1. Allocations. (a) Except as provided in Section 9.1(b),
the income, gains, losses, credits and deductions of the Company for each
Allocation Period shall be determined as of the end of such Allocation Period
and shall be allocated for federal, state and local income tax purposes, to the
extent permitted under the Code and the Treasury Regulations, among the Members
in accordance with the respective LLC Units owned by the Members (as set forth
on the Membership Register) during such Allocation Period, or, in the case of
any such income, gains, losses, credits and deductions arising out of any sale
or other disposition described in clause (i) of the definition of Special
Distribution, in accordance with such LLC Units and the number of Contingent LLC
Units treated as owned by the Members pursuant to the second sentence of Section
9.2. Allocations of income, gains, losses and expenses of the Company for all
other purposes shall be made consistently with the allocations made pursuant to
the immediately preceding sentence.

            (b) In accordance with section 704(c) of the Code and the Treasury
Regulations thereunder, any income, gain, loss, credit and deduction with
respect to any asset contributed to the capital of the Company by any Member
shall, solely for income tax purposes, be allocated among the Members so as to
take account of any variation between the adjusted basis of such asset to the
Company for income tax purposes and its initial Book Value (determined in
accordance with the definition of Book Value set forth in Article I). The method
of allocating such income, gain, loss, credit and deduction shall be such method
set forth in section 1.704-3(b) of the Treasury Regulations. In the event the
Book Value of any asset of the Company is subsequently adjusted in accordance
with the last sentence of such definition of Book Value, subsequent allocations
of any income, gain, loss, credit and deduction with respect to such asset shall
be determined using the principles specified in section 1.704-1(b)(2)(iv)(g) of
the Treasury Regulations and shall take account of any variation between the
adjusted basis of the asset to the Company for income tax purposes and its Book
Value (excluding any portion of such variation subject to the first sentence of
this Section 9.1(b)) in the manner required under section 1.704-1(b)(4)(i) of
the Treasury Regulations, using the method set forth in section 1.704-3(b) of
the Treasury Regulations.

            Section 9.2. Distributions. Any distribution by the Company, whether
in kind or in cash, other than a Special Distribution, shall be made in
accordance with the respective LLC Units owned by the Members (as set forth on
the Membership Register) at the time of such distribution (except that cash
payments may be made 


                                       47
<PAGE>   339

upon the occurrence of a Spin-Off in lieu of distributing fractional interests
in the Subsidiary that is the subject of such Spin-Off). Any Special
Distribution by the Company, whether in kind or in cash, shall be made in
accordance with the respective LLC Units owned by the Members (as set forth on
the Membership Register) (i) at the time of the applicable sale or other
disposition in the case of a sale or other disposition described in clause (i)
of the definition of Special Distribution, and (ii) at the time of the
applicable distribution in the case of a distribution described in clause (ii)
of the definition of Special Distribution (the applicable time described in
clause (i) or (ii) above, the "Measurement Time") (except that cash payments may
be made upon the occurrence of a distribution described in clause (ii) of the
definition of Special Distribution in lieu of distributing fractional interests
in MGI or CERA Inc., as applicable); provided that each Member who, at the
Measurement Time, had a right to receive, under certain circumstances,
Contingent LLC Units pursuant to Section 1.3, 1.4 or 1.5 of the Merger and
Exchange Agreement, shall be treated, solely for the purposes of the applicable
Special Distribution, as if such Member owned the number of Contingent LLC Units
that would have been issuable to such Member, based on the CERA CAGR (as such
term is defined in the Merger and Exchange Agreement) as of the Measurement Time
(as determined in good faith by the Board), if the closing of a Non-qualifying
Sale (as defined in the Merger and Exchange Agreement) had occurred at the
Measurement Time. The Board shall determine in good faith whether a distribution
is a Special Distribution. The Board shall, in its sole discretion, determine
the time and the amount of any distribution, provided that, for each Taxable
Year, the Company shall make a cash distribution to the Members to the extent of
Available Assets in amounts intended to enable the Members (or any Person whose
tax liability is determined by reference to the income of a Member) to discharge
their United States federal, state and local income tax liabilities arising from
the allocations made pursuant to Section 9.1 (the "Tax Liability Distribution"),
except for any such allocations arising out of any variation between the
adjusted tax basis of any asset and its Book Value, and except to the extent
that cash distributions shall have theretofore been made during such Taxable
Year. The amount of any such Tax Liability Distribution shall be determined by
the Board in its sole discretion, taking into account (a) the greater of (i) the
maximum combined tax rate for United States federal, New York State and New York
City income tax purposes, (ii) the maximum combined tax rate for United States
federal and Massachusetts income tax purposes and (iii) the maximum combined tax
rate for United States federal income tax purposes and for purposes of any
income tax imposed by the jurisdiction in which the principal office of the
Company is located, in each case applicable to individuals or corporations
(whichever is higher) on ordinary income and net short-term capital gain or on
net long-term capital gain, as applicable, and taking into account the
deductibility of state and local income taxes for United States federal income
tax purposes and the deductibility of local income taxes for state income tax
purposes (and the assumptions 


                                       48
<PAGE>   340

described in this clause (a) shall be applied equally to each Member regardless
of such Member's place of residence or tax status), and (b) the amounts of
ordinary income, net short-term capital gain and net long-term capital gain so
allocated to the Members, and otherwise based on such reasonable assumptions as
the Board determines in good faith to be appropriate.

            Section 9.3. Withholding. The Company shall withhold and pay over,
or otherwise pay, any withholding or other taxes payable by the Company with
respect to such Member or as a result of such Member's participation in the
Company pursuant to any applicable tax law. If and to the extent that the
Company shall be required to with hold or pay any such taxes, such Member shall
be deemed for all purposes of this Agreement to have received a payment from the
Company as of the time such with holding or tax is required to be paid, which
payment shall be deemed to be a distribution to the extent that such Member is
then entitled to receive a distribution and shall reduce the amount of
distributions otherwise to be made to such Member pursuant to Section 9.2. To
the extent that the aggregate of such payments to a Member for any period
exceeds the distributions to which such Member is entitled for such period, the
amount of such excess shall be considered a loan from the Company to such Member
with interest at the Prime Rate (or the Applicable Federal Rate if the Prime
Rate is less than the Applicable Federal Rate) until discharged by such Member
by repayment, which may be made out of distributions to which such Member would
otherwise be subsequently entitled. The withholdings referred to in this Section
9.3 shall be made at the maximum applicable statutory rate under the applicable
tax law unless the Company shall have received an opinion of counsel or other
evidence, satisfactory to the Company, to the effect that a lower rate is
applicable, or that no withholding is applicable.

            Section 9.4. Restricted Distributions. Notwithstanding any provision
to the contrary contained in this Agreement, the Company shall not make a
distribution to any Member on account of such Member's interest in the Company
if such distribution would violate section 18-607 of the Delaware Act or other
applicable law.


                                    ARTICLE X

                         BOOKS AND RECORDS; TAX MATTERS

            Section 10.1. Books, Records and Financial Statements. (a) At all
times during the continuance of the Company, the Company shall maintain, at its
principal place of business, separate books of account for the Company that
shall show a true and accurate record of all costs and expenses incurred, all
charges made, all 


                                       49
<PAGE>   341

credits made and received and all income derived in connection with the
operation of the Company business in accordance with generally accepted
accounting principles consistently applied, and, to the extent inconsistent
therewith, in accordance with this Agreement. Such books of account, together
with an executed copy of this Agreement and of the Certificate, shall at all
times be maintained at the principal place of business of the Company, and such
books of account and such other materials as may be required to be provided to
any Member pursuant to section 18-305(a) of the Delaware Act shall be open to
inspection and examination at reasonable times during business hours by each
Member and the duly authorized representatives thereof upon reasonable written
notice for any purpose reasonably related to such Member's interest in the
Company, provided that the Directors shall have the right to withhold any such
information pursuant to section 18- 305(c) of the Delaware Act and otherwise
establish such lawful conditions for disclosure of information to the Members as
the Board may deem necessary or appropriate.

            (b) The Treasurer shall prepare and maintain, or cause to be
prepared and maintained, the books of account of the Company.

            (c) The Secretary shall cause to be maintained the Membership
Register.

            Section 10.2. Filings of Returns and Other Writings; Tax Matters
Partner. (a) The Treasurer shall cause the preparation and timely filing of all
Company tax returns and shall, on behalf of the Company, timely file all other
writings required by any governmental authority having jurisdiction to require
such filing. The Company shall use its reasonable best efforts to send, no later
than 60 days after the end of each Taxable Year, to each Person that was a
Member at any time during such Taxable Year copies of (i) United States Internal
Revenue Service Form 1065, "U.S. Partnership Return of Income," or any successor
form, required to be filed by the Company, together with all schedules and
exhibits to such return (including Schedule K-1, "Partner's Share of Income,
Credits, Deductions, Etc.," or any successor schedule or form, for such Person),
together with such additional information (including information with respect to
unrelated business taxable income, if any, within the meaning of section 512 of
the Code, of the Company) as may be necessary for such Person (or any other
Person whose tax liability is determined by reference to the income of such
Person that was a Member and who is identified in writing by such Person that
was a Member to the Company) to file such Person's United States federal income
tax returns and (ii) such similar returns as are required to be filed by the
Company for United States state and local income tax purposes.


                                       50
<PAGE>   342

            (b) Each Member shall provide such information to the Company as may
be reasonably necessary for purposes of the Company's preparing any required tax
return or information return.

            (c) The Board shall appoint a Member who is a Manager as the tax
matters partner (the "Tax Matters Partner") for the Company, who shall meet the
requirements set forth in section 301.6231(a)(7)-2 of the Treasury Regulations
and who shall serve as the Tax Matters Partner until such time as such Member
shall notify the Board that he, she or it is resigning as the Tax Matters
Partner or the Board shall appoint another such Member as the Tax Matters
Partner in accordance with this Section 10.2(c). Each Member hereby consents to
such designation and agrees that upon the request of the Tax Matters Partner,
such Member will execute, certify, acknowledge, deliver, swear to, file and
record at the appropriate public offices such documents as may be necessary or
appropriate to evidence such consent.

            (d) Promptly following the written request of the Tax Matters
Partner, the Company shall, to the fullest extent permitted by law, reimburse
and indemnify the Tax Matters Partner for all reasonable expenses, including
reasonable legal and accounting fees, claims, liabilities, losses and damages
incurred by the Tax Matters Partner in connection with any administrative or
judicial proceeding with respect to the tax liability of the Company or the
Members, except to the extent arising from the bad faith, gross negligence,
willful violation of law, fraud or breach of this Agreement by such Tax Matters
Partner.

            (e) The provisions of this Section 10.2 shall survive the
termination of the Company or the termination of any Member's interest in the
Company and shall remain binding on the Members for as long a period of time as
is necessary to resolve with the Internal Revenue Service any and all matters
regarding the federal income taxation of the Company or the Members.

            Section 10.3. Accounting Method. For both financial and tax
reporting purposes, the books and records of the Company shall be kept on the
accrual method of accounting applied in a consistent manner and shall reflect
all Company transactions.

            Section 10.4. Audits. At any time at the Board's sole discretion,
but at least annually, the financial statements of the Company may be audited by
the independent certified public accountants, with such audit to be accompanied

audits will be an expense of the Company. A copy of any such audited financial

            Section 10.5. Other Tax Matters. (a) The Company shall not elect to
be treated as an association taxable as a corporation for United States federal,
state or local income tax purposes under Treasury Regulations section 301.7701-3
or under any corresponding provision of state or local law.

            (b) The Company shall use its best efforts to structure its
investments and activities so as to avoid the incurrence of any income which is
in the hands of any Member (or any other Person whose tax liability is
determined by reference to the income of a Member) "unrelated business taxable
income" (as such term is defined in section 512 of the Code). The Company will
generally not invest in partnership interests in partnerships or in interests in
other entities treated as partnerships for federal income tax purposes if such
investment would cause any non-United States Person that is a Member (or any
other non-United States Person whose U.S. federal income tax liability is
determined by reference to the income of a Member) to be deemed to be engaged in
a trade or business within the United States pursuant to section 875 of the Code
or any Member (or any other Person whose U.S. federal income tax liability is
determined by reference to the income of a Member) to incur unrelated business
taxable income pursuant to section 512(c) of the Code.

            Section 10.6. Section 754 Election. The Company shall elect,
pursuant to section 754 of the Code, to adjust the basis of the property of the
Company as permitted and provided in sections 734 and 743 of the Code.


                                   ARTICLE XI

                   LIABILITY, EXCULPATION AND INDEMNIFICATION

            Section 11.1. Liability. Except as otherwise provided by the
Delaware Act, the debts, obligations and liabilities of the Company, whether
arising in contract, tort or otherwise, shall be solely the debts, obligations
and liabilities of the Company, and no Covered Person shall be obligated
personally for any such debt, obligation or liability of the Company solely by
reason of being a Covered Person.

            Section 11.2. Exculpation. (a) No Covered Person shall be liable to
the Company or any other Covered Person for any loss, damage or claim incurred
by reason of any act or omission performed or omitted by such Covered Person in
the good faith belief that such action was in, or was not opposed to, the best
interests of the Company and in a manner believed to be within the scope of
authority conferred on such Covered Person by or pursuant to this Agreement,
except that a Covered 


                                       52
<PAGE>   344

Person shall be liable for any such loss, damage or claim incurred by reason of
such Covered Person's gross negligence or willful misconduct.

            (b) A Covered Person shall be fully protected in relying in good
faith upon the records of the Company and upon such information, opinions,
reports or statements presented to the Company by any Person as to matters the
Covered Person believes are within such other Person's professional or expert
competence and who has been selected with reasonable care by or on behalf of the
Company, including information, opinions, reports or statements as to the value
and amount of the assets, liabilities, profits or losses or any other facts
pertinent to the existence and amount of assets from which distributions to
Members might properly be paid.

            Section 11.3. Fiduciary Duty. Subject to the provisions of Section
11.2 and Section 11.6, each Director, Officer and Member of the Company shall be
subject to the fiduciary duties of care and loyalty to the full extent that such
duties would be imposed on, or applicable to, a director, an officer or a
stockholder, respectively, of a corporation organized and existing pursuant to
the General Corporation Law of the State of Delaware (including legislative
history and judicial interpretations and applications thereof); provided that no
Covered Person acting under this Agreement shall be liable to the Company or,
with respect to any matter relating to the Company or its business, to any other
Covered Person for such Person's good faith reliance on the provisions of this
Agreement. The provisions of this Agreement, to the extent that they restrict or
modify the duties and liabilities of a Covered Person otherwise existing at law
or in equity, are agreed by the parties hereto to replace such other duties and
liabilities of such Covered Person.

            Section 11.4. Indemnification. (a) Nature of Indemnity. The Company
shall indemnify any person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of the fact
that he is or was or has agreed to become a Director, Officer, employee or agent
of the Company, or is or was serving or has agreed to serve at the request of
the Company as a director, officer, employee or agent, of another company,
partnership, joint venture, trust or other enterprise, or by reason of any
action alleged to have been taken or omitted in such capacity, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him or on his behalf in connection with such
action, suit or proceeding and any appeal therefrom, if he acted in good faith
and in a manner he reasonably believed to be in or not opposed to the best
interests of the Company, and, with respect to any criminal action or proceeding
had no reasonable cause to believe his conduct was unlawful; except that in the
case of an action or suit by or in the right of the Company to procure a
judg-


                                       53
<PAGE>   345

ment in its favor (1) such indemnification shall be limited to expenses
(including attorneys' fees) actually and reasonably incurred by such person in
the defense or settlement of such action or suit, and (2) no indemnification
shall be made in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the Company unless and only to the
extent that the Delaware Court of Chancery or the court in which such action or
suit was brought shall determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Delaware
Court of Chancery or such other court shall deem proper; provided that any
indemnity under this Section 11.4 shall be provided out of and to the extent of
Company assets only, and no Member or Director, Officer, employee or agent of
the Company shall have any personal liabilities with respect to such indemnity.

            The termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the Company, and, with respect to any criminal
action or proceeding, had reasonable cause to believe that his conduct was
unlawful.

            (b) Successful Defense. To the extent that a Director, Officer,
employee or agent of the Company has been successful on the merits or otherwise
in defense of any action, suit or proceeding referred to in Section 11.4(a)
hereof or in defense of any claim, issue or matter therein, he shall be
indemnified by the Company against expenses (including attorneys' fees) actually
and reasonably incurred by him in connection therewith.

            (c) Determination That Indemnification Is Proper. Any
indemnification under Section 11.4(a) hereof (unless ordered by a court) shall
be made by the Company unless a determination is made that indemnification of
the director, officer, employee or agent is not proper in the circumstances
because he has not met the applicable standard of conduct set forth in Section
11.4(a) hereof. Any such determination shall be made (1) by a majority vote of
the Directors who are not parties to such action, suit or proceeding, even
though less than a quorum, or (2) if there are no such Directors, or, if such
Directors so direct, by independent legal counsel in a written opinion, or (3)
by Members holding at least 66 2/3% of the LLC Units.


                                       54
<PAGE>   346

            (d) Advance Payment of Expenses. To the fullest extent permitted by
Applicable Law, expenses (including attorneys' fees) incurred by a Covered
Person in defending any civil, criminal, administrative or investigative claim,
demand, action, suit or proceeding shall, from time to time, be paid by the
Company in advance of the final disposition of such claim, demand, action, suit
or proceeding upon receipt by the Company of an undertaking by or on behalf of
the Covered Person to repay such amount if it shall ultimately be determined
that the Covered Person is not entitled to be indemnified by the Company as
authorized in this Section 11.4. Such expenses (including attorneys' fees)
incurred by other employees and agents may be so paid upon such terms and
conditions, if any, as the Board deems appropriate. The Board may authorize the
Company's counsel to represent such director, officer, employee or agent in any
action, suit or proceeding, whether or not the Company is a party to such
action, suit or proceeding.

            (e) Procedure for Indemnification of Directors and Officers. Any
indemnification of a person seeking indemnification under Sections 11.4(a) and
11.4(b), or advance of costs, charges and expenses to such person under Section
11.4(d) hereof, shall be made promptly, and in any event within 30 days, upon
the written request of such person. If a determination by the Company that such
person is entitled to indemnification pursuant to this Section 11.4 is required,
and the Company fails to respond within 60 days to a written request for
indemnity, the Company shall be deemed to have approved such request. If the
Company denies a written request for indemnity or advancement of expenses, in
whole or in part, or if payment in full pursuant to such request is not made
within 30 days, the right to indemnification or advances as granted by this
Section 11.4 shall be enforceable by the indemnified person in any court of
competent jurisdiction. Such person's costs and expenses incurred in connection
with successfully establishing his right to indemnification, in whole or in
part, in any such action shall also be indemnified by the Company. It shall be a
defense to any such action (other than an action brought to enforce a claim for
the advance of costs, charges and expenses under Section 11.4(d) where the
required undertaking, if any, has been received by the Company) that the
claimant has not met the standard of conduct set forth in Section 11.4(a) of
this Section 11.4, but the burden of proving such defense shall be on the
Company. Neither the failure of the Company (including its Board and its
independent legal counsel) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he has met the applicable standard of conduct set
forth in Section 11.4(a) hereof, nor the fact that there has been an actual
determination by the Company (including its Board, its independent legal
counsel, or Members holding at least 66 2/3% of the LLC Units) that the claimant
has not met such applicable standard of conduct, shall be a defense to the
action or create a presumption that the claimant has not met the applicable
standard of conduct.


                                       55
<PAGE>   347

            (f) Survival; Preservation of Other Rights. The foregoing
indemnification provisions shall be deemed to be a contract between the Company
and each director, officer, employee and agent who serves in any such capacity
at any time while these provisions are in effect and any modification thereof
shall not affect any right or obligation then existing with respect to any state
of facts then or previously existing or any action, suit or proceeding
previously or thereafter brought or threatened based in whole or in part upon
any such state of facts. Such a "contract right" may not be modified
retroactively without the consent of such director, officer, employee or agent.

            The indemnification and advancement of expenses provided by this
Section 11.4 shall not be deemed exclusive of any other rights to which those
indemnified may be entitled under any provision of this Agreement, vote of
disinterested Directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding such office, and shall
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of the heirs, executors and administrators
of such a person.

            (g) Insurance. The Company may purchase and maintain insurance, to
the extent and in such amounts as the Board shall, in its sole discretion, deem
reasonable, on behalf of Covered Persons and such other Persons as the Board
shall determine, against any liability that may be asserted against or expenses
that may be incurred by any such Person in connection with the activities of the
Company or such indemnities, regardless of whether the Company would have the
power to indemnify such Person against such liability under the provisions of
this Agreement. The Company may enter into indemnity contracts with Covered
Persons and such other Persons as the Board shall determine and adopt written
procedures pursuant to which arrangements are made for the advancement of
expenses and the funding of obligations under Section 11.4(d) hereof and
containing such other procedures regarding indemnification as are appropriate.

            Section 11.5. Severability. To the fullest extent permitted by
applicable law, if any portion of this Article shall be invalidated on any
ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify each person who is or was serving or has agreed to serve
at the request of the Company as a Director, Officer, employee or agent of the
Company, or who is or was serving or has agreed to serve at the request of the
Company as a director, officer, employee or agent of another company,
partnership, joint venture, trust or other enterprise, as to costs, charges and
expenses (including reasonable attorneys' fees), judgments, fines and amounts
paid in settlement with respect to any action, suit or proceeding, whether
civil, criminal, administrative or investigative, including an action by or in
the right of 


                                       56
<PAGE>   348

the Company, to the fullest extent permitted by any applicable portion of this
Article that shall not have been invalidated.

            Section 11.6. Outside Businesses. Any Member or Affiliate thereof
may engage in or possess an interest in other business ventures of any nature or
description, independently or with others, similar or dissimilar to the business
of the Company, and the Company, the Directors and the Members shall have no
rights by virtue of this Agreement in and to such independent ventures or the
income or profits derived therefrom, and the pursuit of any such venture, even
if competitive with the business of the Company, shall not be deemed wrongful or
improper. No Member, Director or Affiliate thereof shall be obligated to present
any particular investment opportunity to the Company even if such opportunity is
of a character that, if presented to the Company, could be taken by the Company,
and any Member, Director or Affiliate thereof shall have the right to take for
such Person's own account (individually or as a partner or fiduciary) or to
recommend to others any such particular investment opportunity, provided that
this Section 11.6 shall not apply to Members who are employees of the Company or
any of its Subsidiaries.


                                   ARTICLE XII

                               ADDITIONAL MEMBERS

            Section 12.1. Admission. By approval of the Board, the Company is
authorized to admit any Person as an additional member of the Company (each, an
"Additional Member" and collectively, the "Additional Members"), subject to
compliance with the provisions of Article XIII of this Agreement. With respect
to the Persons exercising options to purchase LLC Units, each such Person shall
be deemed admitted as a Member upon execution of an LLC Unit Subscription
Agreement and such other documents as may be required pursuant to such LLC Unit
Subscription Agreement and as the Board may reasonably require, and the payment
of the applicable option exercise price, if any. Each Person other than a Person
admitted pursuant to Section 2.1(b) or a Person exercising options to purchase
LLC Units shall be admitted as an Additional Member at the time such Person (i)
executes a counterpart to this Agreement, (ii) complies with the applicable
Board resolution, if any, with respect to such admission and (iii) is named as a
Member in the Membership Register.

                    TRANSFER OF INTERESTS; SUBSTITUTE MEMBERS

            Section 13.1. Restrictions on LLC Unit Transfers. (a) Initial
Holding Period for Restricted Holders. No Member who, together with such
Member's Existing CERA Trusts (if any), owns, as of the date hereof, 5% or more
of the then outstanding LLC Units (any such Member, a "Restricted Holder"), no
Existing CERA Trust and none of such Member's or such trust's Permitted
Transferees who shall have become owners of LLC Units after the date hereof
shall, for a period ending on the earlier of three years after the Closing Date
(the "Initial Holding Period") and one year after the first Underwritten Public
Offering after the date hereof, Transfer any LLC Units (including any Transfer
pursuant to Section 13.2) except, subject to Section 13.1(c), (i) to an
unaffiliated third party (x) in a sale of all of the LLC Units pursuant to
Section 13.4, or (y) pursuant to a merger, conversion, consolidation or
reorganization of the Company, other than a Conversion Transaction (any such
sale, merger, conversion, consolidation or reorganization, a "Fundamental
Transaction"), (ii) in any Conversion Transaction, (iii) in a Public Offering,
(iv) Transfers to a Permitted Transferee or (v) Transfers to the Company or any
Subsidiary of the Company. This Section 13.1(a) shall not apply to Transfers by
MGI or CERA Inc. to the extent such Transfers are otherwise covered in Section
13.1(g).

            (b) Restrictions on Other Transfers. No Member other than a
Restricted Holder, any Existing CERA Trust and any of such Restricted Holder's
or such trust's Permitted Transferees who shall have become owners of LLC Units
after the date hereof, and, after the earlier of the expiration of the Initial
Holding Period and one year after the first Underwritten Public Offering after
the date hereof, no Member, shall Transfer any LLC Units except, subject to
Section 13.1(c), (i) in a Fundamental Transaction, (ii) in a Conversion
Transaction, (iii) in a Public Offering, (iv) for Transfers to a Permitted
Transferee or to any Member who was a Member as of the Closing Date, (v) for
Transfers to the Company or any Subsidiary of the Company, (vi) subject to
compliance with Sections 13.2, 13.3 and 13.4, as applicable, for Transfers to
Restricted Holders or third parties for cash only in transactions which would be
exempt from the registration requirements of section 5 of the Securities Act by
virtue of the exemption provided by section 4(2) of the Securities Act if the
transferor were the issuer of the LLC Units, provided that, for purposes of this
clause (vi), the transferee is an "accredited investor" within the meaning of
Rule 501(a) under the Securities Act or (vii) following the first Underwritten
Public Offering after the date hereof and subject to compliance with Section
13.2 and Rule 144 or Rule 145 (or any successor provision) under the Securities
Act, if applicable, for any other Transfers to third parties. This Section
13.1(b) shall not apply to Transfers made by 


                                       58
<PAGE>   350

MGI or CERA Inc. to the extent such Transfers are covered in Section 13.1(g).

            (c) Transfer Conditions. No Member shall Transfer any LLC Units if
such Transfer would constitute a Prohibited Transaction. The Board shall
evaluate each Transfer request, and the proposed transferor shall furnish such
information as may be requested by the Board, to determine if such Transfer
would constitute a Prohibited Transaction, which determination shall be
conclusive and binding absent manifest error. The Board shall promptly notify
the proposed transferor of the Board's determination. In addition, it shall be a
further condition of any LLC Unit Transfer pursuant to Section 13.1(a)(iv),
13.1(b)(iv) or 13.1(b)(vi) (other than pursuant to Section 13.4) that (i) the
transferee agrees in writing to be bound by the obligations and restrictions
applicable to Members and/or LLC Units under this Agreement, (ii) the
transferring Member and the transferee shall have complied with all requirements
of any applicable LLC Unit Subscription Agreement, (iii) the proposed transferee
provides to the Company the information required pursuant to Section 13.7(c),
and (iv) such transferring Member delivers to the Company (A) an opinion of
counsel, which opinion and counsel shall be reasonably satisfactory to the
Company, to the effect that (1) the Transfer does not violate and will not cause
the Company to be in violation of any Specified Laws, (2) the transferor and the
Specified Affiliate (in the case of a Transfer to a Permitted Transferee
described in clause (iv) of the definition of such term) have made all filings
and obtained all consents of any governmental entity and any other Person
required to be made or obtained by the transferor and the Specified Affiliate,
and have complied with all applicable requirements of Specified Laws in
connection with the Transfer of such LLC Units and (3) the transferring Member
and the transferee have complied with all requirements of this Agreement and any
applicable LLC Unit Subscription Agreement and (B) a certificate setting forth
the basis on which such Transfer is permitted under Section 13.1(a) or 13.1(b),
as the case may be, and, in the case of a Transfer of the type specified in
Section 13.1(b)(vi), describing compliance with Sections 13.2, 13.3 and 13.4, as
applicable.

            (d) Restrictions to Avoid Publicly Traded Partnership Status. (i)
Notwithstanding any other provision to the contrary in this Agreement, until the
settlement date of the first Underwritten Public Offering, no Member shall
Transfer any LLC Interest (other than in a Private Transfer) in any form,
including but not limited to by entering into an Indirect LLC Interest, if such
transfer is made on an Established Securities Market or a Secondary Market.
Except for Transfers of LLC Units pursuant to Section 13.1(a)(i), (ii), (iii) or
(v) or Section 13.1(b)(i), (ii), (iii) or (v), the Member proposing to make any
Transfer of an LLC Interest prior to the settlement date of the first
Underwritten Public Offering shall (A) deliver to the Company a certificate
setting forth the basis on which such Member purports that such Transfer is not
prohibited under the immediately preceding sentence and (B) furnish 


                                       59
<PAGE>   351

such information as may be requested by the Board to determine if such Transfer
would be so prohibited.

            (ii) Until the settlement date of the first Underwritten Public
Offering, the Company shall not (A) allow any LLC Interests to be listed or
traded on an Established Securities Market, (B) participate in the inclusion of
any LLC Interests on any Secondary Market or (C) recognize any Transfer of LLC
Interests (other than a Private Transfer) in any form, including but not limited
to the entering into of an Indirect LLC Interest, if such Transfer is made on an
Established Securities Market or a Secondary Market, including but not limited
to (1) by redeeming the transferor Member (in the case of a redemption or
repurchase by the Company) or (2) by admitting the transferee as a Member or
otherwise recognizing any rights of the transferee, including but not limited to
the right to receive distributions from the Company (directly or indirectly) or
to acquire an interest in the capital or profits of the Company.

            (e) Custody of the LLC Unit Certificates. Unless otherwise agreed to
in writing by the Company, until the settlement date of the first Underwritten
Public Offering after the date hereof, each Member shall maintain such Member's
LLC Unit certificates in custody, pursuant to the Bailment Agreement, dated as
of the date hereof, between the Company, as bailee thereunder, Fund IV, the CERA
Principals and GS LP, substantially in the form of Exhibit B attached hereto,
the terms of which (including any amendments and supplements to such agreement
adopted in accordance with the terms thereof) are hereby acknowledged and agreed
to by, and shall be binding upon, each Member.

            (f) Distributions Following Transfers. The Company shall, from the
effective date of any Transfer permitted under this Section 13.1, thereafter pay
all further distributions on account of the LLC Units (or part thereof) so
transferred to the transferee of such LLC Units (or part thereof). Any Transfer
of LLC Units in violation of this Section 13.1 shall be null and void ab
initio, and the Company shall not register, recognize or give effect to any such
Transfer, nor shall the intended transferee acquire any rights in such LLC Units
for any purposes of this Agreement. All Transfers permitted hereunder are
subject to Section 13.7.

            (g) Transfers Involving MGI or CERA. The Transfer restrictions set
forth in Sections 13.1(a) and (b) shall not apply to transfers by MGI or CERA
Inc. to any Person to whom MGI or CERA Inc., as the case may be, may be
obligated to Transfer LLC Units pursuant to any agreement existing on the date
hereof, the Merger and Exchange Agreement (including the exhibits thereto), any
of the agreements entered into in connection with the transactions contemplated
thereby, or as 


                                       60
<PAGE>   352

contemplated by this Agreement, including (but not limited to) the following
types of Transfers: the grant of LLC Units to the CERA Management Members, the
transfer of the Contingent LLC Units to the CERA Management Members, the
transfer of LLC Units in connection with the exercise of Existing MGI Options,
MGI/CERA Additional Options or any other options granted pursuant to an LLC Unit
Subscription Agreement and transfers to Restricted Holders in connection with
the purchase by MGI or CERA Inc., as the case may be, of LLC Units pursuant to
any LLC Unit Subscription Agreement.

            13.2. Participation Rights. So long as any Registrable Securities
remain outstanding and a Public Market has not been established with respect to
the LLC Units, no Restricted Holder, no Existing CERA Trust and no Permitted
Transferee of any Restricted Holder or any such trust shall make any sale or
transfer of LLC Units owned by such Member, trust or Permitted Transferee which
would constitute a Qualifying Sale, except pursuant to Section 13.4 or the
following provisions of this Section 13.2:

            (a) Procedures for Qualifying Sales. At least 30 days prior to
making any Qualifying Sale, the applicable Restricted Holder, Existing CERA
Trust and/or such Restricted Holder's or such trust's Permitted Transferee will
send a written notice (the "Sale Notice") to the Company and the other holders
of Registrable Securities. The Sale Notice will disclose the identity of the
prospective transferee and the material terms and conditions of the proposed
Qualifying Sale, including the number of LLC Units that the prospective
transferee is willing to purchase and the intended consummation date of such
Qualifying Sale. The Restricted Holder, each of such Restricted Holder's
Existing CERA Trusts and each of such Restricted Holder's and such trusts'
Permitted Transferees that owns any LLC Units agrees not to consummate any
Qualifying Sale until at least 30 days after the related Sale Notice has been
sent to each holder of Registrable Securities, unless the Restricted Holder,
Existing CERA Trust or such Restricted Holder's and/or such trust's Permitted
Transferee, as the case may be, shall have received a notice from each holder of
Registrable Securities indicating whether or not such holder has elected to
participate in such Qualifying Sale and the number of LLC Units to be sold by
each such holder so electing to participate has been finally determined pursuant
hereto prior to the expiration of such 30-day period. Each holder of Registrable
Securities may elect to participate in the contemplated Qualifying Sale by
giving written notice to the applicable Restricted Holder, Existing CERA Trust
and/or such Restricted Holder's or such trust's Permitted Transferee and the
Company within 30 days after such Restricted Holder, Existing CERA Trust or such
Restricted Holder's and/or such trust's Permitted Transferee, as the case may
be, has sent the related Sale Notice to such holder. If a holder of Registrable
Securities elects to participate, such holder will be entitled to sell in the
contem-


                                       61
<PAGE>   353

plated Qualifying Sale, at the same price and on the same terms and conditions
as set forth in the related Sale Notice, an amount of Registrable Securities
equal to the product of (i) the quotient determined by dividing (A) the
percentage of Registrable Securities then held by such holder of Registrable
Securities so electing to participate by (B) the aggregate percentage of
Registrable Securities represented by the Registrable Securities then held by
the selling Restricted Holder, such Restricted Holder's Existing CERA Trusts and
such Restricted Holder's and such trusts' Permitted Transferees and all holders
of Registrable Securities so electing to participate (in each case under this
clause (i) on a partially diluted basis taking into account only such options to
purchase LLC Units as are then exercisable and held by the selling Restricted
Holder, such Existing CERA Trusts, such Permitted Transferees or the holders of
Registrable Securities so electing to participate, as applicable) and (ii) the
number of Registrable Securities such transferee has agreed to purchase in the
contemplated sale (or in the case of a "Qualifying Sale" within the meaning of
clause (ii) of Section 13.2(b), the Excess Number of shares which such
transferee has agreed to purchase). If such right to participate in a Qualifying
Sale shall not have been exercised prior to the expiration of the 30-day period,
then at any time during the 90 days following the expiration of the 30- day
period, subject to extension for not more than an additional 90 days to the
extent reasonably required to comply with Applicable Laws in connection with
such purchase, the Restricted Holder, such Restricted Holder's Existing CERA
Trusts and such Restricted Holder's and such trusts' Permitted Transferees, as
applicable, may sell to the prospective transferee the number of LLC Units and
at the price and on the terms and conditions indicated in the Sale Notice. Upon
request of the Restricted Holder, Existing CERA Trust or such Restricted
Holder's and/or such trust's Permitted Transferee, as the case may be, in
connection with any contemplated Sale Notice, the Company will provide the
Restricted Holder, Existing CERA Trust or such Restricted Holder's and/or such
trust's Permitted Transferee, as the case may be, with a current list of holders
of Registrable Securities and their addresses.

            (b) Qualifying Sale Defined. The term "Qualifying Sale" shall mean
(i) any sale or transfer of LLC Units proposed to be made by a Restricted
Holder, or any of such Restricted Holder's Existing CERA Trusts or such
Restricted Holder's or such trust's Permitted Transferees, pursuant to Section
13.1(b)(vi) or 13.1(b)(vii) (other than any sales or transfers to other
Restricted Holders pursuant to Section 13.3 following compliance with the right
of first offer procedures set forth in Section 13.3), at any time after the
Restricted Holder and/or such Restricted Holder's Existing CERA Trusts or such
Restricted Holder's or such trust's Permitted Transferees have sold or
transferred pursuant to Section 13.1(b)(vi) or 13.1(b)(vii) in the aggregate 5%
of the LLC Units owned by such Restricted Holder and such Restricted Holder's
Existing CERA Trusts, if any, at the time of the Closing and any LLC Units
acquired by such 


                                       62
<PAGE>   354

Restricted Holder, such Existing CERA Trust or any of such Restricted Holder's
or such trust's Permitted Transferees thereafter (the "Qualifying Number") or
(ii) in the event that prior to the sale or transfer by such Restricted Holder,
such Existing CERA Trust and/or such Permitted Transferees of an aggregate of
the Qualifying Number of LLC Units, the Restricted Holder, such Existing CERA
Trust or any of such Restricted Holder's or such trust's Permitted Transferees
proposes to sell or transfer pursuant to Section 13.1(b)(vi) or 13.1(b)(vii) a
number of LLC Units which when combined with any prior such sales or transfers
of LLC Units by such Restricted Holder, such Existing CERA Trust and/or such
Permitted Transferees exceeds the Qualifying Number, the sale or transfer
pursuant to Section 13.1(b)(vi) or 13.1(b)(vii) of a number of LLC Units (the
"Excess Number") equal to the excess of (A) the sum of any LLC Units previously
so sold or transferred by such Restricted Holder, such Existing CERA Trust
and/or such Restricted Holder's or such trust's Permitted Transferees and the
aggregate number of LLC Units proposed to be sold or transferred in such
contemplated sale, over (B) the Qualifying Number of LLC Units. In determining
whether there is a "Qualifying Sale," equitable adjustments shall be made to
reflect any LLC Unit split or combination, distribution of LLC Units,
recapitalization or similar transaction.

            (c) Exclusion from Qualifying Sale. The obligations of a Restricted
Holder, an Existing CERA Trust and such Restricted Holder's and such trust's
Permitted Transferees and the rights of the holders of Registrable Securities
pursuant to this Section 13.2 will not apply to any sale or transfer by the
Restricted Holder, an Existing CERA Trust or any such Permitted Transferee
pursuant to a distribution and/or sale to the public (whether pursuant to a
registered Public Offering, Rule 144, broker's transactions or otherwise (but
not pursuant to Rule 144A under the Securities Act or any successor provision)).
Any LLC Units referred to, or covered by any sale or transfer referred to, in
the preceding sentence shall not be included in the computation of "Qualifying
Sale."

            Section 13.3. First Offer Rights. In the event that any Member (such
Member, an "Offering Member") shall determine to offer to sell or to sell, prior
to the settlement date of the first Underwritten Public Offering after the date
hereof, for cash pursuant to Section 13.1(b)(vi) LLC Units owned by such
Offering Member (the "First Offer LLC Units"):

            (a) Offer Required. The Offering Member shall make an offer (the
"Member Offer") of the First Offer LLC Units, in accordance with this Section
13.3, to the Company (or to MGI or CERA Inc., as applicable, if the Company
shall have assigned its right to accept the applicable Member Offer to MGI or
CERA Inc.) and (if applicable) each Restricted Holder (other than the Offering
Member if the Offering Member is a Restricted Holder).


                                       63
<PAGE>   355

            (b) First Offer Rights; Procedures. If the Offering Member is
required to make a Member Offer pursuant to this Section 13.3, the Offering
Member shall deliver to the Company a written notice (a "Member Offering
Notice") setting forth the number of LLC Units to be offered or sold, the
proposed date of offer or sale (which shall be not less than 70 days after the
date of delivery of the Member Offering Notice), and the terms and conditions of
the proposed offer or sale. The Member Offering Notice shall include an offer to
sell the First Offer LLC Units at the price and on the terms and conditions as
set forth in the Member Offering Notice, which offer by its terms shall remain
open for a period of 60 days from the date of the Company's receipt of the
Member Offering Notice. The Company may assign to MGI or CERA Inc. its right to
accept any Member Offer by delivery of written notice of such assignment to the
Offering Member and MGI or CERA Inc., as applicable, at any time prior to the
21st day after the delivery of the Member Offering Notice to the Company. In the
event of any such assignment, each reference to the Company in this Section
13.3(b) shall be deemed to refer to MGI or CERA Inc., as the case may be, unless
the context otherwise requires. Prior to the 21st day after the delivery of the
Member Offering Notice to the Company, the Company may accept the offer of First
Offer LLC Units in whole or in part by delivering to the Offering Member a
written notice of acceptance setting forth the number of First Offer LLC Units
which the Company shall elect to purchase. If the Company does not elect to
purchase all of the First Offer LLC Units included in the Member Offer, the
Company shall forward the Member Offering Notice to each Restricted Holder,
together with written notice of the number of First Offer LLC Units the Company
shall have elected not to purchase (the "Remaining LLC Units"). In accordance
with the procedures set forth in this Section 13.3 and for a second successive
period of 20 days, each such Restricted Holder shall have the right to elect to
purchase such Restricted Holder's pro rata portion (determined as of the date of
the Member Offering Notice and on a partially diluted basis taking into account
only such options to purchase LLC Units as are then exercisable and held by the
applicable Restricted Holder, and including any LLC Units held by such
Restricted Holder's CERA Trusts) of the Remaining LLC Units by delivering
written notice to the Company setting forth the number of the Remaining LLC
Units such Restricted Holder has so elected to purchase. If such Restricted
Holders in the aggregate do not elect to purchase all of the Remaining LLC
Units, then the Company shall send a written notice to each Restricted Holder
who had elected to purchase all of such Restricted Holder's pro rata portion of
the Remaining LLC Units during such 20-day period, which notice shall state the
number of Remaining LLC Units as to which elections have not been made, and for
a third successive period of 20 days (the "Third Round"), each such Restricted
Holder shall have the right to purchase additional Remaining LLC Units, in an
amount equal to either (i) the product of (x) the number of such Remaining LLC
Units in respect of 


                                       64
<PAGE>   356

which offers to purchase had not been accepted in the prior offering period and
(y) a fraction, the numerator of which shall be the number of LLC Units held by
such Restricted Holder (on a partially diluted basis taking into account only
such options to purchase LLC Units as are then exercisable and held by such
Restricted Holder, and including any LLC Units held by such Restricted Holder's
CERA Trusts) as of the date of the Member Offering Notice and the denominator of
which shall be the aggregate number of LLC Units then held by each Restricted
Holder that had subscribed for all of the Remaining LLC Units offered to such
Restricted Holder in the prior offering period (on a partially diluted basis
taking into account only such options to purchase LLC Units as are then
exercisable and held by any such Restricted Holder, and including any LLC Units
held by such Restricted Holder's CERA Trusts) or (ii) such other amount as shall
be agreed upon by all such Restricted Holders. Upon expiration of the Third
Round in accordance with the procedures set forth above, (x) if the Company and
the Restricted Holders in the aggregate have not accepted the Member Offer with
respect to all of the First Offer LLC Units, the Offering Member may proceed
with the proposed offer and sale of, and sell, all of the First Offer LLC Units
(and the Company and the Restricted Holders shall not be entitled to purchase
any of the First Offer LLC Units), at a price equal to no less than 90% of the
price set forth in the Member Offering Notice and on other terms and conditions
substantially the same as those set forth in the Member Offering Notice, at any
time during a period of 30 days after the last day of the Third Round or (y) if
the Company and the Restricted Holders in the aggregate have accepted the Member
Offer with respect to all of the First Offer LLC Units, the Company and (as
applicable) such Restricted Holders shall purchase from the Offering Member, and
the Offering Member shall sell to the Company and (as applicable) such
Restricted Holders, the First Offer LLC Units, on the terms and conditions
specified in the Member Offering Notice; provided that any Restricted Holder may
revoke such Restricted Holder's acceptance of any Member Offering Notice by
written notice to the Company and the Offering Member at any time within 20 days
following delivery of such Restricted Holder's initial acceptance thereof if
such Restricted Holder is unable to secure financing for such purchase in an
amount and on such terms and conditions as are reasonably acceptable to such
Restricted Holder, in which event the LLC Units covered by such revoked
acceptance shall thereupon be deemed Remaining LLC Units and reoffered, for a
period of 14 days, to each other Restricted Holder that elected to purchase all
of the Remaining LLC Units offered to such Restricted Holder in any offering
period, with such reoffering to be conducted as if such LLC Units were Remaining
LLC Units subject to a Third Round offering, as provided above.

            Section 13.4. Take-Along Rights. (a) Take-Along Notice. Subject to
the prior application of the provisions of Section 13.3, if, prior to the
settlement date of the first Underwritten Public Offering after the date hereof,
the holders of more than 50% (a "Controlling Group") of the LLC Units (including
LLC Units issuable upon exercise 


                                       65
<PAGE>   357

of then exercisable options to purchase LLC Units and such number of Contingent
LLC Units as the Board shall determine would be issuable immediately prior to
the Section 13.4 Closing (as defined below) pursuant to Sections 1.3, 1.4, 1.5
and 1.6 of the Merger and Exchange Agreement based upon the CERA CAGR (as such
term is defined in the Merger and Exchange Agreement) as of the most recent
available date prior to such determination), acting jointly, intend to effect a
sale of all of their LLC Units (including such Contingent LLC Units and, if
applicable, their Contingent Options) to an unaffiliated third party (a "100%
Buyer") and elect to exercise their rights under this Section 13.4, such
Controlling Group shall deliver written notice (a "Take-Along Notice") to the
Company and the other Members (collectively, the "Other LLC Unitholders"), which
notice shall (a) state (i) that the Controlling Group wishes to exercise its
rights under this Section 13.4 with respect to such transfer, (ii) the name and
address of the 100% Buyer, (iii) the per LLC Unit amount and form of
consideration the Controlling Group proposes to receive for its LLC Units and
(iv) drafts of purchase and sale documentation setting forth the terms and
conditions of payment of such consideration and all other material terms and
conditions of such transfer (the "Draft Sale Agreement"), (b) contain an offer
(the "Take-Along Offer") by the 100% Buyer to purchase from the Other LLC
Unitholders all of their LLC Units, Contingent LLC Units and, if applicable,
their Contingent Options, on and subject to the same price, terms and conditions
offered to the Controlling Group and (c) state the anticipated time and place of
the closing of such transfer (a "Section 13.4 Closing"), which (subject to such
terms and conditions) shall occur not fewer than five days nor more than 90 days
after the date such Take-Along Notice is delivered, provided that if such
Section 13.4 Closing shall not occur prior to the expiration of such 90-day
period, the Controlling Group shall be entitled to deliver another Take-Along
Notice with respect to such Take-Along Offer. Upon request of a
Controlling Group, the Company shall provide the Controlling Group with a
current list of the names and addresses of the Other LLC Unitholders.

            (b) Conditions to Take-Along. Upon delivery of a Take-Along Notice,
each of the Other LLC Unitholders shall have the obligation to transfer all of
such LLC Unitholder's LLC Units and Contingent LLC Units and, if applicable,
such LLC Unitholder's Contingent Options pursuant to the Take-Along Offer, as
such offer may be modified from time to time, provided that the Controlling
Group transfers all of its LLC Units and Contingent LLC Units and, if
applicable, its Contingent Options to the 100% Buyer at the Section 13.4 Closing
and that all LLC Units held by the Controlling Group and the Other LLC
Unitholders are sold to the 100% Buyer at the same price, and on the same terms
and conditions. In the event that any such Other LLC Unitholder shall determine
that the transfer of such LLC Unitholder's LLC Units, Contingent LLC Units or
Contingent Options to the 100% Buyer would constitute a prohibited transaction
under ERISA or the Code, such Other LLC Unitholder shall use 


                                       66
<PAGE>   358

reasonable best efforts to structure the transfer in a manner that would not
constitute a non-exempt prohibited transaction, including requesting an
individual exemption from the Department of Labor with respect to such transfer
and any other reasonable action. Within 10 days of receipt of the Take-Along
Notice, each of the Other LLC Unitholders shall (i) deliver or cause to be
delivered to the member or an Affiliate of the member of the Controlling Group
designated in the Take-Along Notice (the "Custodian") certificates representing
such Other LLC Unitholder's LLC Units, duly endorsed for transfer or accompanied
by duly executed instruments of transfer, and/or such agreements or other
instruments as shall be requested by the 100% Buyer to effect the transfer of
the Contingent LLC Units, and (ii) execute and deliver to the Custodian a power
of attorney and a letter of transmittal and custody agreement in favor of the
Custodian, and in form and substance reasonably satisfactory to the Controlling
Group, appointing the Custodian as the true and lawful attorney-in-fact and
custodian for such Other LLC Unitholder, with full power of substitution, and
authorizing the Custodian to execute and deliver a purchase and sale agreement
substantially in the form of the Draft Sale Agreement and to take such actions
as the Custodian may deem necessary or appropriate to effect the sale and
transfer of the LLC Units to the 100% Buyer, upon receipt of the purchase price
therefor set forth in the Take-Along Notice at the Section 13.4 Closing, free
and clear of all security interests, liens, claims, encumbrances, charges,
options, restrictions on transfer, proxies and voting and other agreements of
whatever nature, together with all other documents delivered with such Notice
and required to be executed in connection with the sale thereof pursuant to the
Take-Along Offer. The Custodian shall hold such LLC Units and other documents in
trust for such Other LLC Unitholder pending completion or abandonment of such
sale. If, within 90 days after the Controlling Group delivers the Take-Along
Notice, the Controlling Group has not completed the sale of all of the LLC Units
owned by the Controlling Group and the Other LLC Unitholders to the 100% Buyer
and another Take- Along Notice with respect to such Take-Along Offer has not
been sent to the Other LLC Unitholders, the Custodian shall return to each Other
LLC Unitholder all certificates representing the LLC Units and all other
documents that such Other LLC Unitholder delivered in connection with such sale.
The Controlling Group shall be permitted to send only two Take-Along Notices
with respect to any one Take-Along Offer. Promptly after the Section 13.4
Closing, the Custodian shall give notice thereof to the Other LLC Unitholders,
shall remit to each of the Other LLC Unitholders the total consideration for the
LLC Units of such Other LLC Unitholders sold pursuant thereto, and shall furnish
such other evidence of the completion and time of completion of such sale and
the terms thereof as may reasonably be requested by any of the Other LLC
Unitholders.

            (c) Remedies. Each of the Other LLC Unitholders acknowledges that
the Controlling Group would be irreparably damaged in the event of a breach or a


                                       67
<PAGE>   359

threatened breach by such Other LLC Unitholder of any of such LLC Unitholder's
obligations under this Section 13.4 and each of the Other LLC Unitholders agrees
that, in the event of a breach or a threatened breach by such Other LLC
Unitholder of any such obligation, the Controlling Group shall, in addition to
any other rights and remedies available to it in respect of such breach, be
entitled to an injunction from a court of competent jurisdiction (without any
requirement to post bond) granting it specific performance by such Other LLC
Unitholder of such LLC Unitholder's obligations under this Section 13.4. In the
event that the Controlling Group shall file suit to enforce the covenants
contained in this Section 13.4 (or obtain any other remedy in respect of any
breach thereof), the prevailing party in the suit shall be entitled to recover,
in addition to all other damages to which such party may be entitled, the costs
incurred by such party in conducting the suit, including reasonable attorneys'
fees and expenses. In the event that, following a breach by any Other LLC
Unitholder of the provisions of this Section 13.4, the Controlling Group does
not obtain an injunction granting it specific performance of such LLC
Unitholder's obligations under this Section 13.4 in connection with any proposed
sale prior to the time the Controlling Group completes the sale of its LLC Units
or the Controlling Group, in its sole discretion, abandons such sale, then the
Company shall have the option to purchase the LLC Units from such Other LLC
Unitholder at a purchase price per LLC Unit equal to the price per LLC Unit at
which such LLC Units were originally purchased from the Company or, if such LLC
Units were obtained by such Other LLC Unitholder pursuant to the Transactions,
equal to the amount of such Other LLC Unitholder's deemed capital contribution
per LLC Unit pursuant to Section 8.2.

            Section 13.5. Members' Rights to Purchase Additional LLC Units. (a)
Restricted Holder Sale. If at any time after the date of this Agreement and
prior to the establishment of a Public Market with respect to the LLC Units, the
Company shall propose to issue or sell any additional LLC Units to any
Restricted Holder or any Affiliate (other than such officers or employees of or
consultants to the Company or any of its Subsidiaries who are not Restricted
Holders) of any Restricted Holder (a "Restricted Holder Sale"), the Company
shall offer to each holder of Registrable Securities that is an accredited
investor (as such term is defined in Rule 501 of Regulation D under the
Securities Act) the right to purchase that number of additional LLC Units, on
the same terms and conditions as the proposed Restricted Holder Sale, such that
such holder would have the opportunity to hold the same percentage of LLC Units
(on a partially diluted basis taking into account only such options to purchase
LLC Units as are then exercisable) after giving effect to the Restricted Holder
Sale, as such holder held immediately prior thereto (an "Offer").
Notwithstanding the foregoing, none of the following transactions shall
constitute a Restricted Holder Sale: the issuance by the Company of (x) any
Contingent LLC Units or (y) any LLC Units (A) pursuant to the Transactions, (B)
in connection with the transfer to the CERA 


                                       68
<PAGE>   360

Management Members promptly following the date hereof as described in the tenth
recital hereof, (C) in exchange for Voting LLC Units, (D) upon conversion of
Non-Voting LLC Units pursuant to Section 8.7 hereof, (E) upon or in connection
with exercise of Existing MGI Options or MGI/CERA Additional Options, (F) upon
or in connection with exercise of options granted pursuant to an LLC Unit
Subscription Agreement or (G) upon exercise of the CERA Contingent Options or
the GS Contingent Options.

            (b) Offer Procedures. The Company shall make an Offer by delivering
to each holder of Registrable Securities at least 30 Business Days' prior
written notice of the proposed Restricted Holder Sale. Such notice will identify
the class and number of LLC Units (the "Offered Securities"), the proposed date
of issuance and the price and other terms of the issuance. Such notice will also
include an offer to sell to each such holder that number of the Offered
Securities such that such holder would have the opportunity to hold the same
percentage of LLC Units (on a partially diluted basis taking into account only
such options to purchase LLC Units as are then exercisable) after giving effect
to the Restricted Holder Sale, as such holder held immediately prior thereto
(such holder's "Proportionate Share"), at the same price and on the same other
terms as are proposed for such Restricted Holder Sale, which offer by its terms
shall remain open for a period of 15 Business Days from the date of receipt of
such notice, provided that in the event that the Offered Securities are
Non-Voting LLC Units, any holder not required by law to hold non-voting
securities of the Company may purchase such holder's Proportionate Share in
shares of Voting LLC Units. Each such holder shall give notice to the Company of
such holder's intention to accept an Offer prior to the end of the 15-Business
Day period of such Offer, setting forth such portion of the Offered Securities
which such holder elects to purchase. If any holder fails to subscribe in full
for such holder's Proportionate Share of the Offered Securities, the other
subscribing holders shall be entitled to purchase such Offered Securities as are
not subscribed for by such holder in such proportion of the Offered Securities
as they shall have theretofore agreed to purchase until there are no unmet
demands of subscribing holders or all Offered Securities shall have been
subscribed for. The Company shall notify each holder five (5) Business Days
following the expiration of the 15-Business Day period described above of the
amount of Offered Securities which each such holder may purchase pursuant to the
foregoing sentence, and each such holder shall then have 10 Business Days from
the delivery of such notice to indicate such additional amount, if any, that
such holder wishes to purchase. Upon the closing of the Restricted Holder Sale
as to which the Company has given notice, such holder shall purchase from the
Company, and the Company shall sell to such holders, the Offered Securities
subscribed for by such holders on the terms specified in the Offer, which shall
be the same terms at which all other Persons acquire such securities in
connection with such sale or issuance. In the event that 


                                       69
<PAGE>   361

such holders do not subscribe for all of the Offered Securities, the Company
shall have 30 Business Days from the end of the foregoing 15-Business Day or
30-Business Day period, whichever is applicable, to sell all or any part of such
Offered Securities as to which such holders have not accepted an Offer to any
other Persons, in all material respects on terms and conditions that are no more
favorable to such other Persons or less favorable to the Company than those set
forth in the Offer. Any Offered Securities not purchased by such holders or
other Persons in accordance with this Section 13.5 may not be sold or otherwise
disposed of by the Company until they are again offered to such holders under
the procedures specified in this Section 13.5.

            Section 13.6.  Registration Rights. (a) The Members shall have the 
registration rights set forth in Schedule C hereto.

            (b) In the event of a determination by the Company, made in
accordance with the provisions of this Agreement, to cause (i) a Transfer of all
or substantially all of (x) the assets of the Company or (y) the LLC Units to a
newly organized stock corporation or other business entity ("Newco"), (ii) a
merger of the Company into a Newco by merger or consolidation as provided under
section 18-209 of the Delaware Act or otherwise or (iii) any other restructuring
of the LLC Units, in any case in anticipation of a Public Offering, each Member
shall take such steps to effect such Transfer, merger, consolidation or other
restructuring as may be requested by the Company, including, without limitation,
Transferring such Member's LLC Units to Newco in exchange for capital stock of
Newco; provided that no Member shall be required to take any action or omit to
take any action to the extent such action or omission violates Applicable Law.
In addition or alternatively, subject to Section 7.1, the terms and provisions
of this Agreement may be amended at any time by the Company to permit the
Company to register LLC Units under the Securities Act, which amendments may
include, without limitation, any changes in form and structure as may be deemed
by the Company to be necessary, convenient, desirable or incidental to
facilitate the public offering of LLC Units and may cause, among other things,
the Company or its successor to be taxed as a corporation.

            Section 13.7. Substitute Members. In the event any Member Transfers
such Member's LLC Units in compliance with the other provisions of this Article
XIII, the transferee thereof shall become a Substitute Member of the Company
only upon satisfaction of the following:

            (a) such Member and such transferee shall execute such instruments
      as the Board or any Officer deems reasonably necessary or desirable to
      effect such substitution;


                                       70
<PAGE>   362

            (b) the transferee of such Member's LLC Units accepts and agrees in
      writing to be bound by all of the terms and provisions of this Agreement;
      and

            (c) the transferee of such Member's LLC Units accepts and agrees in
      writing to provide the Company with such information, including its
      employer identification number or social security number, as applicable,
      and the amount paid for the LLC Units, as the Company may in its
      discretion request from time to time.

The Board in its sole discretion may agree to waive any or all of the conditions
set forth in subparagraphs (a) through (c) of this Section 13.7.

            Section 13.8. Release of Liability. In the event any Member shall
sell or otherwise dispose of (other than by a pledge or collateral assignment)
all the LLC Units which such Member owns, in compliance with the provisions of
this Agreement without retaining any interest therein, then the selling Member
shall cease to be a Member, and shall be relieved of any further liability
arising hereunder for events occurring from and after the date of such Transfer.

                                   ARTICLE XIV

                    DISSOLUTION, LIQUIDATION AND TERMINATION

            Section 14.1. Dissolving Events. The Company shall be dissolved in
the manner hereinafter provided upon the happening of any of the following
events:

            (a) the Board and the Members shall vote or agree in writing to
      dissolve the Company pursuant to Section 5.1(b)(iv) or 4.4(f), as
      applicable; or

            (b) any event which under Applicable Law would cause the dissolution
      of the Company, provided that, unless required by law, the Company shall
      not be wound up as a result of any such event and the business of the
      Company shall be continued.

Notwithstanding the foregoing, the death, retirement, resignation, expulsion,
bankruptcy or dissolution of any Member or the occurrence of any other event
that terminates the continued membership of any Member in the Company under the
Delaware Act shall not, in and of itself, cause the dissolution of the Company.
In such event, the remaining Member(s) shall continue the business of the
Company without dissolution.


                                       71

            Section 14.2. Dissolution and Winding-Up. Upon the dissolution of
the Company, the assets of the Company shall be liquidated or distributed under
the direction of and to the extent determined by the Board and the business of
the Company wound up, provided that this Agreement shall remain in full force
and effect, notwithstanding any prior dissolution of the Company, until
termination of the Company in accordance with Section 14.3. Within a reasonable
time after the effective date of dissolution of the Company, the Company's
assets shall be distributed in the following manner and order:

            (a) to all creditors of the Company, to the extent otherwise
      permitted by law, in satisfaction of liabilities of the Company, including
      any amounts the Company may owe under the indemnity provided in Section
      11.4 hereof (whether by payment or the making of reasonable provision for
      payment thereof); and

            (b) with respect to any remaining proceeds, to make distributions to
      the Members in accordance with Section 9.2;

provided that no payment or distribution in any of the foregoing categories
shall be made until all obligations in each prior category shall have been
satisfied in full, and provided, further, that if the payments due to be made in
any of the foregoing categories exceed the remaining assets available for such
purpose, such payments shall be made to the Persons within such categories
entitled to receive the same pro rata in accordance with the respective amounts
due to them.

            Section 14.3. Termination. The Company shall terminate when the

Company have been distributed and the Certificate has been canceled, all in
accordance with the Delaware Act.

shall look solely to the Company's assets for the return of their capital
contributions, and if the assets of the Company remaining after payment of or
due provision for all debts, liabilities and obligations of the Company are
insufficient to return such capital contributions, the Members and former
Members shall not be entitled to have such capital contributions returned to
them and shall have no recourse against the Company or any other Member.

the following effect in place of the legend set forth above:

Any LLC Unit certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon the
completion of a public distribution of securities of the Company represented
thereby or otherwise if the holder of the LLC Units represented by such
certificate shall have delivered to the Company an opinion of counsel, which
opinion and counsel shall be reasonably satisfactory to the Company, that the
Securities Act permits such certificate to be issued without such legend or with
a legend modified as set forth in such opinion) shall also bear such legend. The
provisions of this Agreement shall be binding upon, and shall inure to the
benefit of, the Members and all subsequent holders of LLC Units who acquired the
same directly or indirectly from a Member to the extent set forth herein. The
Company agrees that it will not transfer on its books any certificate
representing LLC Units in violation of the provisions of this Agreement.

of securities, recapitalization, liquidation or similar transaction where the
LLC Units are converted into or exchanged for other securities, all references
in this Agreement (including the Schedules hereto) to LLC Units shall be deemed
to refer to such securities into which the LLC Units shall have been converted
or for which the LLC Units shall have been exchanged.

                                   SCHEDULE C

            This Schedule C describes certain registration rights of the holders
of Registrable Securities (collectively, the "LLC Unitholders"). Capitalized
terms used herein without definition shall have the meanings set forth in the
Amended and Restated Limited Liability Company Agreement, dated as of
______________, 1997 (the "Agreement"), of Global Decisions Group LLC, a
Delaware limited liability company (the "Company"). In the event that, at the
time any rights under Section 13.6 of the Agreement are exercised, the equity
securities of the Company or its successor are not comprised of limited
liability company interests of a limited liability company, all references
herein to LLC Units shall be deemed to refer to such equity securities and the
other provisions of this Schedule C shall be appropriately applied, with such
adjustment as shall be necessary to give effect to the intent of such
provisions. The words "hereby," "herein," "hereof," "hereunder" and words of
similar import refer to this Schedule C as a whole and not merely to the
specific section, paragraph or clause in which such word appears. All references
herein to Sections shall be deemed references to this Schedule C unless the
context shall otherwise require.

            1.1   Registration Upon Request.

            (a) Requests. Subject to the provisions of Section 1.6, at any time
or from time to time (i) the Requisite Percentage of LLC Unitholders shall have
the right to make one or more written requests, and (ii) the Requisite
Percentage of CERA Principals shall have the right to make two (2) written
requests, that the Company effect the registration under the Securities Act of
all or part of the Registrable Securities of the holder or holders of such
securities and their trusts making such request, which requests shall specify
the intended method of disposition thereof by such holder or holders of such
securities and their trusts.

            (b) Obligation to Effect Registration. Upon receipt by the Company
of any request for registration pursuant to Section 1.1(a), the Company will
promptly give written notice of such requested registration to all holders of
Registrable Securities, and thereupon will use its best efforts to effect the
registration under the Securities Act of

            (i) the Registrable Securities which the Company has been so
      requested to register pursuant to Section 1.1(a), and
<PAGE>   377

            (ii) all other Registrable Securities which the Company has been
      requested to register by the holders thereof by written request given to
      the Company within 30 days after the Company has given such written notice
      (which request shall specify the intended method of disposition of such
      Registrable Securities),

all to the extent required to permit the disposition (in accordance with the
intended methods thereof as aforesaid) of the Registrable Securities so to be
registered. Notwithstanding the preceding sentence:

            (x) the Company shall not be required to effect a registration
      requested (a) pursuant to Section 1.1(a)(i) if the aggregate number of
      Registrable Securities referred to in clauses (i) and (ii) of this Section
      1.1(b) included in such registration shall be less than 20% of the
      Registrable Securities at the time outstanding and (b) pursuant to Section
      1.1(a)(ii) if the aggregate number of Registrable Securities referred to
      in clauses (i) and (ii) of this Section 1.1(b) included in such
      registration shall be, in the case of the first request, less than 50%,
      and in the case of the second request, less than one-third, of the LLC
      Units held by the CERA Principals (including LLC Units held by CERA
      Trusts) on the Closing Date; and

            (y) if the Board determines in its good faith judgment, after
      consultation with a firm of nationally recognized underwriters, that there
      will be an adverse effect on a then contemplated initial Underwritten
      Public Offering of LLC Units, then the Requisite Percentage of LLC
      Unitholders or the Requisite Percentage of CERA Principals, as the case
      may be, shall be given notice of such fact and shall be deemed to have
      withdrawn such request and such registration shall not be deemed to have
      been effected or requested pursuant to this Section 1.1.

            (c) Registration Statement Form. Each registration requested
pursuant to this Section 1.1 shall be effected by the filing of a registration
statement on Form S-1, Form S-2 or Form S-3 (or any other form which includes
substantially the same information as would be required to be included in a
registration statement on such forms as presently constituted), unless the use
of a different form is (i) required by law or (ii) permitted by law and agreed
to in writing by holders holding at least a majority (by number of LLC Units) of
the Registrable Securities as to which registration has been requested pursuant
to this Section 1.1. At any time after the date hereof that the Company shall
have issued and sold any LLC Units registered under an effective registration
statement under the Securities Act, or after the Company shall have registered
any class of equity securities pursuant to Section 12 of the Exchange 


                                       2
<PAGE>   378

Act, it will use its best efforts to qualify for registration on Form S-2 or
Form S-3 (or any other comparable form hereinafter adopted).

            (d) Expenses. The Company will pay all Registration Expenses in
connection with the first two registrations which are effected as requested
under Section 1.1(a) (i) and each of the two registrations which are effected as
requested under Section 1.1(a)(ii). The Registration Expenses in connection with
each other registration, if any, requested under this Section 1.1 shall be
apportioned among the holders whose Registrable Securities are then being
registered, on the basis of the respective amounts (by number of LLC Units) of
Registrable Securities then being registered by them or on their behalf.
However, in the case of all registrations requested under Section 1.1(a), the
Company shall pay all amounts in respect of (i) any allocation of salaries of
personnel of the Company and its Subsidiaries or other general overhead expenses
of the Company and its Subsidiaries or other expenses for the preparation of
financial statements or other data normally prepared by the Company and its
Subsidiaries in the ordinary course of its business, (ii) the expenses of any
officers' and directors' liability insurance, (iii) the expenses and fees for
listing the securities to be registered on each exchange on which similar
securities issued by the Company are then listed or, if no such securities are
then listed on an exchange selected by the Company and (iv) all fees associated
with filings required to be made with the NASD (including, if applicable, the
fees and expenses of any "qualified independent underwriter" and its counsel as
may be required by the rules and regulations of the NASD).

            (e) Inclusion of Other Securities. The Company shall not register
securities (other than Registrable Securities) for sale for the account of any
Person other than the Company in any registration requested pursuant to Section
1.1(a) unless permitted to do so by the written consent of holders holding at
least a majority (by number of LLC Units) of the Registrable Securities
proposed to be sold in such registration.

            (f) Effective Registration Statement. A registration requested
pursuant to Section 1.1(a) will not be deemed to have been effected unless it
has become effective for the period specified in Section 1.3(b). Notwithstanding
the preceding sentence, a registration requested pursuant to Section 1.1(a)
which does not become effective after the Company has filed a registration
statement with respect thereto solely by reason of the refusal to proceed of the
holder or holders of Registrable Securities requesting the registration shall be
deemed to have been effected by the Company at the request of such holder or
holders.


                                       3
<PAGE>   379

            (g) Pro Rata Allocation. If the holders of a majority (by number of
LLC Units) of the Registrable Securities for which registration is being
requested pursuant to Section 1.1(a) determine, based on consultation with the
managing underwriters or, in an offering which is not underwritten, with an
investment banker, that the number of securities to be sold in any such
offering should be limited due to market conditions or otherwise, all holders of
Registrable Securities proposing to sell their securities in such registration
shall share pro rata in the number of securities being offered (as determined by
the holders holding a majority (by number of LLC Units) of the Registrable
Securities for which registration is being requested in consultation with the
managing underwriters or investment banker, as the case may be) and registered
for their account, such sharing to be based on the number of Registrable
Securities as to which registration was requested by such holders, and any
securities that the Company shall have proposed to sell for its own account in
such offering shall be included only if all Registrable Securities as to which
registration was requested are included therein.

            1.2. Incidental Registration. If the Company at any time proposes to
register any of its equity securities (as defined in the Exchange Act) under the
Securities Act (other than pursuant to Section 1.1 or pursuant to a Special
Registration), whether or not for sale for its own account, and the registration
form to be used may be used for the registration of Registrable Securities, it
will each such time give prompt written notice to all holders of Registrable
Securities of its intention to do so and of such holders' rights under this
Section and, upon the written request of any holder of Registrable Securities
given to the Company within 30 days after the Company has given any such notice
(which request shall specify the Registrable Securities intended to be disposed
of by such holder and the intended method of disposition thereof), the Company
will use its best efforts to effect the registration under the Securities Act of
all Registrable Securities which the Company has been so requested to register
by the holders thereof, to the extent required to permit the disposition (in
accordance with the intended methods thereof as aforesaid) of the Registrable
Securities so to be registered, provided that:

            (a) if such registration shall be in connection with the
      Underwritten Public Offering of the Common Stock, the Company shall not
      include any Registrable Securities in such proposed registration if the
      Board shall have deter mined, after consultation with the managing
      underwriters for such offering, that it is not in the best interests of
      the Company to include any Registrable Securities in such registration,
      provided that, if the Board makes such a determination, the Company shall
      not include in such registration any securities not being sold for the
      account of the Company;


                                       4
<PAGE>   380

            (b) if, at any time after giving written notice of its intention to
      register any securities and prior to the effective date of the
      registration statement filed in connection with such registration, the
      Company shall determine for any reason not to register such securities,
      the Company may, at its election, give written notice of such
      determination to each holder of Registrable Securities or other securities
      that was previously notified of such registration and, thereupon, shall
      not register any Registrable Securities in connection with such
      registration (but shall nevertheless pay the Registration Expenses in
      connection therewith), without prejudice, however, to the rights of any
      holder or holders of Registrable Securities to request that a registration
      be effected under Section 1.1;

            (c) if the Company shall be advised in writing by the managing
      underwriters (or, in connection with an offering which is not
      underwritten, by an investment banker) (and the Company shall so advise
      each holder of Registrable Securities requesting registration of such
      advice) that in their or its opinion the number of securities requested to
      be included in such registration (whether by the Company, pursuant to this
      Section 1.2 or pursuant to any other rights granted by the Company to a
      holder or holders of its securities to request or demand such registration
      or inclusion of any such securities in any such registration) exceeds the
      number of such securities which can be sold in such offering,

                  (i) the Company shall include in such registration the number
            (if any) of Registrable Securities so requested to be included which
            in the opinion of such underwriters or investment banker, as the
            case may be, can be sold and shall not include in such registration
            any securities (other than securities being sold by the Company,
            which shall have priority in being included in such registration) so
            requested to be included other than Registrable Securities unless
            all Registrable Securities requested to be so included are included
            therein, and

                  (ii) if in the opinion of such underwriters or investment
            banker, as the case may be, some but not all of the Registrable
            Securities may be so included, all holders of Registrable Securities
            requested to be included therein shall share pro rata in the number
            of Registrable Securities included in such Underwritten Public
            Offering on the basis of the number of Registrable Securities
            requested to be included therein by such holders, provided that, in
            the case of a registration initially requested or demanded by a
            holder or holders of securities other than Registrable Securities,
            the holders of the Registrable Securities 


                                       5
<PAGE>   381

            requested to be included therein and the holders of such other
            securities shall share pro rata (based on the number of LLC Units if
            the requested or demanded registration is to cover only LLC Units
            and, if not, based on the proposed offering price of the total
            number of securities included in such Underwritten Public Offering
            requested to be included therein),

      and the Company shall so provide in any registration agreement hereinafter
      entered into with respect to any of its securities; and

            (d) if prior to the effective date of the registration statement
      filed in connection with such registration, the Company is informed by the
      managing underwriter (or, in connection with an offering which is not
      underwritten, by an investment banker) that the price at which such
      securities are to be sold is a price below that price which the requesting
      holders shall have indicated to be acceptable, the Company shall promptly
      notify the requesting holders of such fact, and each such requesting
      holder shall have the right to withdraw its request to have its
      Registrable Securities included in such registration statement.

            The Company will pay all Registration Expenses in connection with
each registration of Registrable Securities requested pursuant to this Section
1.2. No registration effected under this Section 1.2 shall relieve the Company
from its obligation to effect registrations upon request under Section 1.1.

            1.3. Registration Procedures. If and whenever the Company is
required to use its best efforts to effect the registration of any Registrable
Securities under the Securities Act as provided in Sections 1.1 and 1.2, the
Company will promptly:

            (a) subject to clauses (x) and (y) of Section 1.1(b), prepare and
      file with the Commission a registration statement with respect to such
      securities, make all required filings with the NASD and use best efforts
      to cause such registration statement to become effective;

            (b) prepare and file with the Commission such amendments and
      supplements to such registration statement and the prospectus used in
      connection therewith and such other documents as may be necessary to keep
      such registration statement effective and to comply with the provisions of
      the Securities Act with respect to the disposition of all securities
      covered by such registration statement until such time as all of such
      securities have been disposed of in accordance with the intended methods
      of disposition by the seller or sellers thereof set forth in such
      registration statement, but in no event 


                                       6
<PAGE>   382

      for a period of more than six months after such registration statement 
      becomes effective;

            (c) furnish to counsel (if any) selected by the holders of a
      majority (by number of LLC Units) of the Registrable Securities covered by
      such registration statement copies of all documents proposed to be filed
      with the Commission in connection with such registration, which documents
      will be subject to the review of such counsel;

            (d) furnish to each seller of such securities, without charge, such
      number of conformed copies of such registration statement and of each such
      amendment and supplement thereto (in each case, including all exhibits and
      documents filed therewith (other than those filed on a confidential
      basis), except that the Company shall not be obligated to furnish any
      seller of securities with more than two copies of such exhibits and
      documents), such number of copies of the prospectus included in such
      registration statement (including each preliminary prospectus and any
      summary prospectus) in conformity with the requirements of the Securities
      Act, and such other documents, as such seller may reasonably request in
      order to facilitate the disposition of the securities owned by such
      seller;

            (e) use its best efforts (x) to register or qualify the securities
      covered by such registration statement under such other securities or blue
      sky laws of such jurisdictions as each seller shall request, (y) to keep
      such registration or qualification in effect for so long as such
      registration statement remains in effect and (z) to do any and all other
      acts and things which may be necessary or advisable to enable such seller
      to consummate the disposition in such jurisdictions of the securities
      owned by such seller, except that the Company shall not for any such
      purpose be required to qualify generally to do business as a foreign
      corporation in any jurisdiction wherein it is not so qualified, subject
      itself to taxation in any jurisdiction wherein it is not so subject, or
      take any action which would subject it to general service of process in
      any jurisdiction wherein it is not so subject;

            (f) in connection with an Underwritten Public Offering only, furnish
      to each seller a signed counterpart, addressed to the sellers, of

                  (i)  an opinion of counsel for the Company experienced in
            securities law matters, dated the effective date of the registration
            statement, and


                                       7
<PAGE>   383

                  (ii) a "comfort" letter signed by the independent public
            accountants who have issued an audit report on the Company's
            financial statements included in the registration statement, subject
            to such seller having executed and delivered to the independent
            public accountants such certificates and documents as such
            accountants shall reasonably request and provided that such
            accountants shall be permitted by the standards applicable to
            certified public accountants to deliver a "comfort" letter to such
            seller,

      covering substantially the same matters with respect to the registration
      statement (and the prospectus included therein) and, in the case of such
      accountants' letter, with respect to events subsequent to the date of such
      financial statements, as are customarily covered in opinions of issuer's
      counsel and in accountants' letters delivered to the underwriters in
      Underwritten Public Offerings of securities;

            (g) (i) notify each holder of Registrable Securities covered by such
      registration statement if such registration statement, at the time it or
      any amendment thereto became effective, (x) contained an untrue statement
      of a material fact or omitted to state a material fact required to be
      stated therein or necessary to make the statements therein not misleading
      upon discovery by the Company of such material misstatement or omission or
      (y) upon discovery by the Company of the happening of any event as a
      result of which the Company believes there would be such a material
      misstatement or omission, and, as promptly as practicable, prepare and
      file with the Commission a post-effective amendment to such registration
      statement and use best efforts to cause such post-effective amendment to
      become effective such that such registration statement, as so amended,
      shall not contain an untrue statement of a material fact or omit to state
      a material fact required to be stated therein or necessary to make the
      statements therein not misleading, and (ii) notify each holder of
      Registrable Securities covered by such registration statement, at any time
      when a prospectus relating thereto is required to be delivered under the
      Securities Act, if the prospectus included in such registration
      statement, as then in effect, includes an untrue statement of a material
      fact or omits to state a material fact required to be stated therein or
      necessary to make the statements therein, in light of the circumstances
      under which they were made, not misleading upon discovery by the Company
      of such material misstatement or omission or upon discovery by the Company
      of the happening of any event as a result of which the Company believes
      there would be a material misstatement or omission, and, as promptly as is
      practicable, prepare and furnish to such holder a reasonable number of
      copies of a supplement to or an amendment of such prospectus as 


                                       8
<PAGE>   384

      may be necessary so that, as thereafter delivered to the purchasers of
      such securities, such prospectus shall not include an untrue statement of
      a material fact or omit to state a material fact required to be stated
      therein or necessary to make the statements therein, in light of the
      circumstances under which they were made, not misleading;

            (h) otherwise use its best efforts to comply with all applicable
      rules and regulations of the Commission, and make available to its
      security holders, as soon as reasonably practicable, an earnings statement
      of the Company complying with the provisions of Section 11(a) of the
      Securities Act and Rule 158 under the Securities Act;

            (i) notify each seller of any securities covered by such
      registration statement (i) when such registration statement, or any
      post-effective amendment to such registration statement, shall have become
      effective, or any amendment of or supplement to the prospectus used in
      connection therewith shall have been filed, (ii) of any request by the
      Commission to amend such registration statement or to amend or supplement
      such prospectus or for additional information, (iii) of the issuance by
      the Commission of any stop order suspending the effectiveness of such
      registration statement or of any order preventing or suspending the use of
      any preliminary prospectus, and (iv) of the suspension of the
      qualification of such securities for offering or sale in any jurisdiction,
      or of the institution of any proceedings for any of such purposes;

            (j) use its best efforts (i) (A) to list such securities on any
      securities exchange on which the LLC Units are then listed or, if no LLC
      Units are then listed, on an exchange selected by the Company, if such
      listing is then permitted under the rules of such exchange or (B) if such
      listing is not practicable or the Board determines that quotation as a
      NASDAQ security is preferable, to secure designation of such securities as
      a NASDAQ "national market system security" within the meaning of Rule
      11Aa2-1 under the Exchange Act and (ii) to provide and cause to be
      maintained a transfer agent and registrar for such Registrable Securities
      not later than the effective date of such registration statement; and

            (k) use every reasonable effort to obtain the lifting of any stop
      order that might be issued suspending the effectiveness of such
      registration statement or of any order preventing or suspending the use of
      any preliminary prospectus, provided that if the Company is unable to
      obtain the lifting of any such stop order in connection with a
      registration pursuant to Section 1.1(a), the request for registration
      shall not be deemed exercised for purposes of determining 


                                       9
<PAGE>   385

      whether such registration has been effected for purposes of Section 1.1(a)
      or (d).

            The Company may require each seller of any securities as to which
any registration is being effected to furnish to the Company such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing and as shall be required by law
in connection therewith. Each such holder agrees to furnish promptly to the
Company all information required to be disclosed in order to make the
information previously furnished to the Company by such holder not materially
misleading.

            The Company agrees not to file or make any amendment to any
registration statement with respect to any Registrable Securities, or any
amendment of or supplement to the prospectus used in connection therewith, which
refers to any seller of any securities covered thereby by name, or otherwise
identifies such seller as the holder of any securities of the Company, without
the consent of such seller, such consent not to be unreasonably withheld, except
that no such consent shall be required for any disclosure that is required by
law.

            By acquisition of Registrable Securities, each holder of such
Registrable Securities shall be deemed to have agreed that upon receipt of any
notice from the Company pursuant to Section 1.3(g), such holder will promptly
discontinue such holder's disposition of Registrable Securities pursuant to the
registration statement covering such Registrable Securities until such holder
shall have received, in the case of clause (i) of Section 1.3(g), notice from
the Company that such registration statement has been amended, as contemplated
by Section 1.3(g), and, in the case of clause (ii) of Section 1.3(g), copies of
the supplemented or amended prospectus contemplated by Section 1.3(g). If so
directed by the Company, each holder of Registrable Securities will deliver to
the Company (at the Company's expense) all copies, other than permanent file
copies, in such holder's possession of the prospectus covering such Registrable
Securities at the time of receipt of such notice. In the event that the Company
shall give any such notice, the period mentioned in Section 1.3(b) shall be
extended by the number of days during the period from and including the date of
the giving of such notice to and including the date when each seller of any
Registrable Securities covered by such registration statement shall have
received the copies of the supplemented or amended prospectus contemplated by
Section 1.3(g).

            Although Voting LLC Units, Non-Voting LLC Units and LLC Units issued
upon the exercise of options are included in the definition of Registrable
Securities, the Company shall, in respect of any such Registrable Securities
requested to be


                                       10
<PAGE>   386

registered pursuant hereto, be required to include in any registration statement
only Voting LLC Units.

            1.4. Underwritten Offerings. The provisions of this Section 1.4 do
not establish additional registration rights but instead set forth procedures
applicable, in addition to those set forth in Sections 1.1 through 1.3, to any
registration which is an underwritten offering.

            (a) Underwritten Offerings Exclusive. Whenever a registration
requested pursuant to Section 1.1 is for an underwritten offering, only
securities which are to be distributed by the underwriters may be included in
the registration.

            (b) Underwriting Agreement. If requested by the underwriters for any
underwritten offering by holders of Registrable Securities pursuant to a
registration requested under Section 1.1(a), the Company shall enter into an
underwriting agreement with such underwriters for such offering, such agreement
to be reasonably satisfactory in substance and form to the holders of a majority
(by number of LLC Units) of the Registrable Securities to be covered by such
registration and to the underwriters and to contain such representations and
warranties by the Company and such other terms and provisions as are customarily
contained in agreements of this type, including, but not limited to, indemnities
to the effect and to the extent provided in Section 1.7, provisions for the
delivery of officers' certificates, opinions of counsel and accountants'
"comfort" letters and hold-back arrangements. The holders of Registrable
Securities to be distributed by such underwriters shall be parties to such
underwriting agreement and may, at their option, require that any or all of the
representations and warranties by, and the agreements on the part of, the
Company to and for the benefit of such underwriters be made to and for the
benefit of such holders of Registrable Securities and that any or all of the
conditions precedent to the obligations of such underwriters under such
underwriting agreement shall also be conditions precedent to the obligations of
such holders of Registrable Securities. In the event that any condition to the
obligations under any such underwriting agreement are not met or waived, and
such failure to be met or waived is not attributable to the fault of the selling
LLC Unitholders requesting a demand registration pursuant to Section 1.1(a),
such request for registration shall not be deemed exercised for purposes of
determining whether such registration has been effected for purposes of Section
1.1(a) or (d). No holder of Registrable Securities shall be required by the
Company to make any representations or warranties to, or agreements with, the
Company or the underwriters other than as set forth in Sections 1.4(e) and
1.7(b), representations, warranties or agreements regarding such holder and such
holder's intended method of distribution and any other representations required
by applicable law.

<PAGE>   387

            (c) Selection of Underwriters. Whenever a registration requested
pursuant to Section 1.1(a) is for an underwritten offering, the Company will
have the right to select the managing underwriters to administer the offering
(subject to the consent (not to be unreasonably withheld) of the holders of a
majority of the LLC Units requested to be registered by CERA Principals
(including the CERA Trusts) in the case of a registration requested pursuant to
Section 1.1(a)(ii)), which managing underwriters shall be underwriters of
nationally recognized standing. If the Company at any time pro poses to register
any of its securities under the Securities Act for sale for its own account and
such securities are to be distributed by or through one or more underwriters,
the Company will have the right to select the managing underwriters to
administer the offering at least one of which shall be an underwriter of
nationally recognized standing.

            (d) Incidental Underwritten Offerings. Subject to the provisions of
the proviso to the first sentence of Section 1.2, if the Company at any time
proposes to register any of its equity securities under the Securities Act
(other than pursuant to Section 1.1 or pursuant to a Special Registration),
whether or not for its own account, and such securities are to be distributed by
or through one or more underwriters, the Company will give prompt written notice
to all holders of Registrable Securities of its intention to do so and, if
requested by any holder of Registrable Securities, will use its best efforts to
arrange for such underwriters to include the Registrable Securities to be
offered and sold by such holder among those to be distributed by such
underwriters. The holders of Registrable Securities to be distributed by such
underwriters shall be parties to the under writing agreement between the Company
and such underwriters and may, at their option, require that any or all of the
representations and warranties by, and the other agreements on the part of, the
Company to and for the benefit of such underwriters shall also be made to and
for the benefit of such holders of Registrable Securities and that any or all of
the conditions precedent to the obligations of the underwriters under such
underwriting agreement shall also be conditions precedent to the obligations of
such holders of Registrable Securities. No such holder of Registrable
Securities shall be required by the Company to make any representations or
warranties to, or agreements with, the Company or the underwriters other than as
set forth in Sections 1.4(e) and 1.7(b), representations, warranties or
agreements regarding such holder and such holder's intended method of
distribution and any other representations required by applicable law.

            (e) Hold Back Agreements. If and whenever the Company proposes to
register any of its equity securities under the Securities Act, whether or not
for its own account (other than pursuant to a Special Registration), or is
required to use its best efforts to effect the registration of any Registrable
Securities under the Securities Act pursuant to Section 1.1 or 1.2, each holder
of Registrable Securities agrees by acquisi-


                                       12
<PAGE>   388

tion of such Registrable Securities not to effect (other than pursuant to such
registration) any public sale or distribution, including, but not limited to,
any sale pursuant to Rule 144 or Rule 144A, of any Registrable Securities, any
other equity securities of the Company or any securities convertible into or
exchangeable or exercisable for any equity securities of the Company for one
year after, and during the 20 days prior to, the effective date of such
registration and the Company agrees to cause each holder of any equity security,
or of any security convertible into or exchangeable or exercisable for any
equity security, of the Company purchased from the Company at any time other
than in a Public Offering to enter into a similar agreement with the Company.
The Company further agrees not to effect (other than pursuant to such
registration or pursuant to a Special Registration) any public sale or
distribution, or to file any registration statement (other than such
registration or a Special Registration) covering any, of its equity securities,
or any securities convertible into or exchangeable or exercisable for such
securities, during the 20 days prior to, and for one year after, the effective
date of such registration if required by the managing underwriter.

            1.5. Preparation; Reasonable Investigation. In connection with the
preparation and filing of each registration statement registering Registrable
Securities under the Securities Act, the Company will give the holders of such
Registrable Securities so to be registered and their underwriters, if any, and
their respective counsel and accountants the opportunity to participate in the
preparation of such registration statement, each prospectus included therein or
filed with the Commission, and each amendment thereof or supplement thereto, and
will give each of them such access to its books and records and such
opportunities to discuss the business of the Company with its officers and the
independent public accountants who have issued audit reports on its financial
statements as shall be necessary, in the opinion of such holders' and such
underwriters' respective counsel, to conduct a reasonable investigation within
the meaning of the Securities Act.

            1.6. Other Registrations. If and whenever the Company is required to
use its best efforts to effect the registration of any Registrable Securities
under the Securities Act pursuant to Section 1.1 or 1.2, and if such
registration shall not have been withdrawn or abandoned, the Company shall not
be obligated to and shall not file any registration statement with respect to
any of its securities (including Registrable Securities) under the Securities
Act (other than a Special Registration), whether of its own accord or at the
request or demand of any holder or holders of such securities, until a period of
six months shall have elapsed from the effective date of such previous
registration; and the Company shall so provide in any registration rights
agreement with respect to any of its equity securities.

            1.7.  Indemnification.

            (a) Indemnification by the Company. In the event of any registration
of any Registrable Securities under the Securities Act pursuant to Section 1.1
or 1.2, the Company will and hereby does indemnify and hold harmless each seller
of such securities, its directors, officers, and employees, each other person
who participates as an underwriter, broker or dealer in the offering or sale of
such securities and each other person, if any, who controls such seller or any
such participating person within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act, against any and all losses,
claims, damages or liabilities, joint or several, to which such seller or any
such director, officer, employee, participating person or controlling person may
become subject under the Securities Act or otherwise (including, without
limitation, the reasonable fees and expenses of legal counsel incurred in
connection with any claim for indemnity hereunder), insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue
statement of a fact contained in any registration statement under which such
securities were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained therein or related thereto, or
any amend ment or supplement thereto, or (ii) any omission or alleged omission
to state a fact required to be stated in any such registration statement,
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement or necessary to make the statements therein not misleading; and the
Company will reimburse such seller and each such director, officer, employee,
participating person and controlling person for any legal or any other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, liability, action or proceeding, provided that the Company
shall not be liable in any such case to the extent that any such loss, claim,
dam age, liability or expense arises out of or is based upon an untrue statement
or omission made in such registration statement, any such preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by such seller or participating person expressly for use in the
preparation thereof and provided, further, that the Company shall not be liable
in any such case to the extent that any such loss, claim, damage, liability or
expense arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission in the prospectus, if such untrue
statement or alleged untrue statement or omission or alleged omission is
completely corrected in an amendment or supplement to the prospectus and the
seller of Registrable Securities thereafter fails to deliver such prospectus as
so amended or supplemented prior to or concurrently with the sale of Registrable
Securities to the person asserting such loss, claim, damage, liability or
expense after the Company had furnished such seller with a sufficient number of
copies of the same or if the seller received notice from the Company 


                                       14
<PAGE>   390

of the existence of such untrue statement or alleged untrue statement or
omission or alleged omission and the seller continued to dispose of Registrable
Securities prior to the time of the receipt of either (A) an amended or
supplemented prospectus which completely corrected such untrue statement or
omission or (B) a notice from the Company that the use of the existing
prospectus may be resumed. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller or any such
director, officer, employee, participating person or controlling person and
shall survive the transfer of such securities by such seller.

            (b) Indemnification by the Sellers. In the event of any registration
of any Registrable Securities under the Securities Act pursuant to Section 1.1
or 1.2, each of the prospective sellers of such securities will indemnify and
hold harmless the Company, each director of the Company, each officer of the
Company who shall sign such registration statement, each other person who
participates as an underwriter, broker or dealer in the offering or sale of such
securities and each other person, if any, who controls the Company or any such
participating person within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act, against any and all losses, claims, damages or
liabilities, joint or several, to which the Company or any such director,
officer, employee, participating person or controlling person may become subject
under the Securities Act or otherwise (including, without limitation, the
reasonable fees and expenses of legal counsel incurred in connection with any
claim for indemnity hereunder), insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of or are
based upon any untrue statement or alleged untrue statement of a fact contained
in, or any omission or alleged omission to state a fact with respect to such
seller required to be stated in, any registration statement under which such
securities were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained therein or related thereto, or
any amendment or supplement thereto, if such statement or omission was made in
reliance upon and in conformity with written information furnished to the
Company by such seller expressly for use in the preparation of such registration
statement, preliminary prospectus, final prospectus, summary prospectus,
amendment or supplement; and the seller will reimburse the Company and each such
director, officer, employee, participating person and controlling person for
any legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding, provided that the liability of each such seller will be in
proportion to and limited to the net amount received by such seller (after
deducting any underwriting discount and expenses) from the sale of Registrable
Securities pursuant to such registration statement. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
the Company or any such director, officer, participating person or controlling
person and shall survive the transfer of such securities by such seller.

<PAGE>   391

            (c) Notices of Claims, etc. Promptly after receipt by an indemnified
party of notice of the commencement of any action or proceeding involving a
claim referred to in the preceding paragraphs of this Section 1.7, such
indemnified party will, if a claim in respect thereof is to be made against an
indemnifying party hereunder, give written notice to the latter of the
commencement of such action, provided that the failure of any indemnified party
to give notice as provided therein shall not relieve the indemnifying party of
its obligations under the preceding paragraphs of this Section 1.7. In case any
such action is brought against an indemnified party, the indemnifying party will
be entitled to participate therein and to assume the defense thereof, jointly
with any other indemnifying party similarly notified to the extent that it may
wish, with counsel reasonably satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party will not be liable to such
indemnified party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof, provided that if such indemnified
party and the indemnifying party reasonably determine, based upon advice of
their respective independent counsel, that a conflict of interest may exist
between the indemnified party and the indemnifying party with respect to such
action and that it is advisable for such indemnified party to be represented by
separate counsel, such indemnified party may retain other counsel, reasonably
satisfactory to the indemnifying party, to represent such indemnified party, and
the indemnifying party shall pay all reasonable fees and expenses of such
counsel. No indemnifying party, in the defense of any such claim or litigation,
shall, except with the consent of such indemnified party, which consent shall
not be unreasonably withheld, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such indemnified party of a release from all
liability in respect to such claim or litigation.

            (d) Other Indemnification. Indemnification similar to that specified
in the preceding paragraphs of this Section 1.7 (with appropriate modifications)
shall be given by the Company and each seller of Registrable Securities with
respect to any required registration or other qualification of such Registrable
Securities under any Federal or state law or regulation of governmental
authority other than the Securities Act.

            (e) Other Remedies. If for any reason the foregoing indemnity under
Section 1.7(a) or (b) is unavailable, or is insufficient to hold harmless an
indemnified party, other than by reason of the exceptions provided therein, then
the indemnifying party and the indemnified party under Section 1.7(a) or (b)
shall contribute to the amount paid or payable by the indemnified party as a
result of such losses, claims, damages, liabilities or expenses (i) in such
proportion as is appropriate to reflect the 


                                       16
<PAGE>   392

relative fault of the indemnifying party on the one hand and the indemnified
party on the other or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, or provides a lesser sum to the indemnified party
than the amount hereinafter calculated, in such proportion as is appropriate to
reflect not only the relative fault of the indemnifying party on the one hand
and the indemnified party on the other but also the relative benefits received
by the indemnifying party and the indemnified party from the offering of
Registrable Securities (taking into account the portion of the proceeds of the
offering realized by each such party) as well as any other relevant equitable
considerations. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. Any party's obligation to contribute pursuant to this Section
1.7(e) is several (in proportion to the relative value of their Registrable
Securities covered by a registration statement) and not joint with the
obligations of any other party. No party shall be liable for contribution under
this Section 1.7(e) except to the extent and under such circumstances as such
party would have been liable to indemnify under this Section 1.7 if such
indemnification were enforceable under applicable law.

            (f) Officers and Directors. As used in this Section 1.7, the terms
"officers" and "directors" shall include the partners of the holders of
Registrable Securities which are partnerships and the trustees of CERA trusts.

            (g) Indemnification Payments. The indemnification and contribution
required by this Section 1.7 shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, as and when bills are
received or expense, loss, damage or liability is incurred; provided that in the
event it is ultimately determined that any amounts so paid were not subject to
indemnification or contribution hereunder, the recipient thereof shall promptly
return such amounts to payor thereof.

Section 262. Appraisal rights

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to [sec.] 228
of this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to [sec.] 251 (other than a merger effected pursuant to [sec.]
251(g) of this title), [sec.] 252, [sec.] 254, [sec.] 257, [sec.] 258, [sec.]
263 or [sec.] 264 of this title:

     (1) Provided, however, that no appraisal rights under this section shall be
available for the shares of any class or series of stock, which stock, or
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did not
require for its approval the vote of the stockholders of the surviving
corporation as provided in subsection (f) of [sec.] 251 of this title.

     (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series of
stock of a constituent corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation pursuant to [secs.] 251, 252,
254, 257, 258, 263 and 264 of this title to accept for such stock anything
except:

          a. Shares of stock of the corporation surviving or resulting from such
merger or consolidation, or depository receipts in respect thereof;

          b. Shares of stock of any other corporation, or depository receipts in
respect thereof, which shares of stock (or depository receipts in respect
thereof) or depository receipts at the effective date of the merger or
consolidation will be either listed on a national securities exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or held of record
by more than 2,000 holders;

          c. Cash in lieu of fractional shares or fractional depository receipts
described in the foregoing subparagraphs a. and b. of this paragraph; or

          d. Any combination of the shares of stock, depository receipts and
cash in lieu of fractional shares or fractional depository receipts described in
the foregoing subparagraphs a., b. and c. of this paragraph.

<PAGE>   396

     (3) In the event all of the stock of a subsidiary Delaware corporation
party to a merger effected under [sec.] 253 of this title is not owned by the
parent corporation immediately prior to the merger, appraisal rights shall be
available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

     (1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with respect to shares for which appraisal rights are available pursuant to
subsection (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations, and shall include in such notice
a copy of this section. Each stockholder electing to demand the appraisal of his
shares shall deliver to the corporation, before the taking of the vote on the
merger or consolidation, a written demand for appraisal of his shares. Such
demand will be sufficient if it reasonably informs the corporation of the
identity of the stockholder and that the stockholder intends thereby to demand
the appraisal of his shares. A proxy or vote against the merger or consolidation
shall not constitute such a demand. A stockholder electing to take such action
must do so by a separate written demand as herein provided. Within 10 days after
the effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with this subsection and has not voted in favor of or consented to
the merger or consolidation of the date that the merger or consolidation has
become effective; or

     (2) If the merger or consolidation was approved pursuant to [sec.] 228 or
[sec.] 253 of this title, each constituent corporation, either before the
effective date of the merger or consolidation or within ten days thereafter,
shall notify each of the holders of any class or series of stock of such
constituent corporation who are entitled to appraisal rights of the approval of
the merger or consolidation and that appraisal rights are available for any or
all shares of such class or series of stock of such constituent corporation, and
shall include in such notice a copy of this section; provided that, if the
notice is given on or after the effective date of the merger or consolidation,
such notice shall be given by the surviving or resulting corporation to all such
holders of any class or series of stock of a constituent corporation that are
entitled to appraisal rights. Such notice may, and, if given on or after the
effective date of the merger or consolidation, shall, also notify such
stockholders of the effective date of the merger or consolidation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of such notice, demand in writing from the surviving or resulting
corporation the appraisal of such holder's shares. Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
such holder's shares. If such notice did not notify stockholders of the
effective date of the merger or consolidation, either (i) each such constituent
corporation shall send a second notice before the effective date of the merger
or consolidation notifying each of the holders of any class or series of stock
of such constituent corporation that are entitled to appraisal rights of the
effective date of the merger or consolidation or (ii) the surviving or resulting
corporation shall send such a second notice to all such holders on or within 10
days after such effective date; provided, however, that if such second notice is
sent more than 20 days following the sending of the first notice, such second
notice need only be sent to each stockholder who is entitled to appraisal rights
and who has demanded appraisal of such holder's shares in accordance with this
subsection. An affidavit of the secretary or assistant secretary or of the
transfer agent of the corporation that is required 





                                       2

to give either notice that such notice has been given shall, in the absence of
fraud, be prima facie evidence of the facts stated therein. For purposes of
determining the stockholders entitled to receive either notice, each constituent
corporation may fix, in advance, a record date that shall be not more than 10
days prior to the date the notice is given, provided, that if the notice is
given on or after the effective date of the merger or consolidation, the record
date shall be such effective date. If no record date is fixed and the notice is
given prior to the effective date, the record date shall be the close of
business on the day next preceding the day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting

                                       3

corporation or by any stockholder entitled to participate in the appraisal
proceeding, the Court may, in its discretion, permit discovery or other pretrial
proceedings and may proceed to trial upon the appraisal prior to the final
determination of the stockholder entitled to an appraisal. Any stockholder whose
name appears on the list filed by the surviving or resulting corporation
pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
