PART I.  INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS

         The information required by Part I of Form S-8 is included in documents
sent or given to participants in the Cambridge Energy Research Associates,
Inc. LLC Unit Grant Plan, the Cambridge Energy Research Associates, Inc. LLC
Unit Option Plan, the MCM Group, Inc. LLC Unit Option Plan, and the MCM Group,
Inc. Stock Option Plan pursuant to Rule 428(b)(1) of the Securities Act of
1933, as amended (the "Securities Act").  Cambridge Energy Research
Associates, Inc. ("CERA") and MCM Group, Inc. ("MGI") are wholly owned
subsidiaries of Global Decisions Group LLC (the "Registrant").

PART II.  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

         Item 3.  INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

         The following documents, which are filed with the Securities and
Exchange Commission (the "Commission"), are incorporated in this Registration
Statement by reference:

         (1) The Registrant's Prospectus filed with Commission pursuant to Rule
424(b)(3) of the Securities Act, dated January 29, 1998, which contains audited
financial statements for the Registrant's latest fiscal year.

         (2) All other reports filed pursuant to Sections 13(a) or 15(d) of the
Exchange Act since the end of the fiscal year covered by the Prospectus referred
to in (1) above.

         All other documents subsequently filed by the Registrant pursuant to
Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of
a post-effective amendment which indicates that all units of capital
representing limited liability company interests in the Registrant ("Units")
offered hereby have been sold or which deregisters all Units then remaining
unsold, shall be deemed to be incorporated by reference herein and to be part
hereof from the date of the filing of such documents.

         Item 4.  DESCRIPTION OF SECURITIES

         The following summary of certain provisions of the Units does not
purport to be complete and is subject to, and qualified in its entirety by the
provisions of, applicable law and the provisions of the Registrant's Amended and
Restated Limited Liability Company Agreement (the "LLC Agreement") which is
filed herewith as Exhibit 4.2. Capitalized terms used in this Registration
Statement and not defined herein have the meaning ascribed to them in the
Registrant's Prospectus filed with Commission pursuant to Rule 424(b)(3) of the
Securities Act, dated January 29, 1998.

         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 of the Registrant (the "Board")
in its sole discretion without approval of the members of the Registrant (the
"Members"). Members (i) will be entitled to receive, to the extent of available
cash and cash equivalent assets of the Registrant, 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 Registrant as may be determined by the Board in its sole discretion, (iii)
will be allocated income, gains, losses, credits and deductions of the
Registrant 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 Internal Revenue Code and regulations promulgated thereunder,
and (iv) will be entitled on a pro rata basis, upon dissolution and liquidation
of the Registrant, to

                                       -1-

<PAGE>   4



all remaining assets after satisfaction of the Registrant'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 Registrant 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, (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 Registrant 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 Registrant's
chief executive officer, or shall be called by the chairman or secretary 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, except as otherwise required by law, 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 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 Registrant, (ii) dissolution of the Registrant and (iii) the sale or other
disposition of all or substantially all of the assets of the Registrant or the
sale or other disposition of all of the capital stock of MGI or CERA owned by
the Registrant, other than in a spin-off of all of the capital stock of MGI or
CERA. Pursuant to the LLC Agreement, 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 in the Registrant's Prospectus filed with Commission
pursuant to Rule 424(b)(3) of the Securities Act, dated January 29, 1998.

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

         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

                                       -2-

<PAGE>   5



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 the LLC Agreement and under the heading "--Take-Along Rights,"
below, or (B) pursuant to a merger, conversion, consolidation or reorganization
of the Registrant, other than in a transaction described in the following clause
(ii), (ii) pursuant to certain transactions where the organizational form of the
Registrant 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
Registrant or any subsidiary of the Registrant.

         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 the LLC Agreement and under the headings
"--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 Registrant and/or any of the Registrant'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, be admitted as a substitute Member only upon (a) execution
by the transferee and the transferor of such instruments as the Board or any
officer of the Registrant 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
Registrant 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 Registrant may request from time to time, (ii) it is
a condition to any transfer of Units that (x) the Board determines that the
proposed transfer will not cause the Registrant to violate applicable law or the
terms of any then outstanding indebtedness of the Registrant, guarantees of
indebtedness or related documents, result in the Registrant 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
Registrant (A) an opinion of counsel reasonably satisfactory to the Registrant
relating to certain

                                       -3-

<PAGE>   6



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 with respect to such
admission, and (C) is named as a Member in the Registrant's membership register,
and (iv) transfers of Units prior to the IPO Date are subject to certain further
restrictions designed to ensure that the Registrant is not treated as a publicly
traded partnership for tax purposes.

         SECURITIES LAWS. The issuance of the Units pursuant to the Merger and
the Units issuable upon the exercise of the Brera Options and the Jordan Options
will be registered under the Securities Act and such Units (other than Units
issued to "affiliates" of MGI or the Registrant) will be freely transferable
under the Securities Act. However, there is no public trading market for the
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 Registrant) 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 Registrant (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
Registrant (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 under the heading "--Restrictions on
Transfer," above, such holder must first make an offer to sell such Units to the
Registrant and, if the Registrant 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 Registrant. 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

                                       -4-

<PAGE>   7



Registrant (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 Registrant 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 Registrant 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 Registrant agrees 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 Registrant 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, the largest unitholder,
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
Registrant is 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
Registrant otherwise undertaken by the Registrant.

         Item 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Not applicable.

         Item 6.  INDEMNIFICATION

         Section 18-108 of the Delaware Limited Liability Company Act (the
"Delaware Act") provides that, subject to such standards and restrictions, if
any, as are set forth in its limited liability company agreement, a limited
liability company may, and shall have the power to, indemnify and hold harmless
any member or manager or other person from and against any and all claims and
demands whatsoever.

         Section 11.2 of the LLC Agreement provides that no Covered Person (as
defined in the LLC Agreement) shall be liable to the Registrant 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
Registrant and in the manner believed to be within the scope of authority
conferred on such Covered Person by or pursuant to the LLC Agreement, except

                                       -5-

<PAGE>   8



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

         Section 11.4 of the LLC Agreement provides that the Registrant shall
indemnify any person who was or is a party or who 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 Registrant, or is or was serving or has agreed to serve at the request of
the Registrant 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 Registrant, 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 Registrant to
procure a judgment in its favor (1) such indemnification shall be limited to
expenses (including attorney's 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 Registrant 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 Section 11.4 shall be provided out of and to
the extent of Registrant assets only, and no Member or Director, Officer,
employee or agent of the Registrant shall have any personal liabilities with
respect to such indemnity.

         Section 11.4 of the LLC Agreement further provides that to the extent
that a Director, Officer, employee or agent of the Registrant has been
successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Section 11.4 thereof or in defense of any claim, issue
or matter therein, he shall be indemnified by the Registrant against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

         Section 11.4 of the LLC Agreement further provides that the Registrant
may purchase and maintain insurance, to the extent and in the 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 Registrant or such
indemnities, regardless of whether the Registrant would have the power to
indemnify such Person against such liability under the provisions of the LLC
Agreement. The Registrant 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 the relevant provisions of the LLC
Agreement and containing such other procedures regarding indemnification as are
appropriate.

         Section 10.5 of the CERA LLC Unit Option Plan, Section 10.5 of the MGI
LLC Unit Option Plan, and Section 10.5 of the MGI Stock Option Plan each
provides as follows (all capitalized terms in this paragraph not defined herein
have the meaning ascribed to them in the relevant Plan): each person who is or
shall have been a member of the Board or the LLC Board or any committee of the
Board or the LLC Board shall be indemnified and held harmless by CERA or MGI, as
the case may be (the relevant entity hereinafter referred to as the "Company"),
and its Subsidiaries to the fullest extent permitted by

                                       -6-

law from and against any and all losses, costs, liabilities and expenses
(including any related attorneys' fees and advances thereof) in connection with,
based upon or arising or resulting from any claim, action, suit or proceeding to
which he may be made a party or in which he may be involved by reason of any
action taken or failure to act under the Plan and from and against any and all
amounts paid by him in settlement thereof, with the Company's approval, or paid
by him in satisfaction of any judgment in any such action, suit or proceeding
against him, provided that he shall give the Company or, with the consent of the
Company, another member of the MGI/CERA Group an opportunity, at its own
expense, to defend the same before he undertakes to defend it on his own behalf.
The foregoing right of indemnification shall not be exclusive and shall be
independent of any other rights of indemnification to which such persons may be
entitled under the Company's or any such Subsidiary's certificate of
incorporation or by-laws, by contract, as a matter of law, or otherwise.

         The Registrant carries a general liability insurance policy which
covers certain liabilities of Directors and Officers of the Registrant arising
out of claims based on acts or omissions in their capacity as Directors or
Officers.

         Item 7.  EXEMPTION FROM REGISTRATION CLAIMED

         Not applicable.

         Item 8.  EXHIBITS

         The Exhibit Index immediately preceding the exhibits is incorporated
herein by reference.

         Item 9.  UNDERTAKINGS

         1.       The Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

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

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

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

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

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

                                       -7-

<PAGE>   10




         2. The Registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference
in the Registration Statement shall be deemed to be a new Registration Statement
relating to the Units offered therein, and the offering of such Units at that
time shall be deemed to be the initial bona fide offering thereof.

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

         Section 4.1. Powers of Members. The Members shall have the power to
exercise any and all rights or powers granted to the Members pursuant to the
express terms of this Agreement. Except as otherwise required by law, on all
matters submitted to the Members for a vote, the holders of Non-Voting LLC Units
shall have no right to vote with respect to such LLC Units. The approval or
consent of the Members shall not be required in order to authorize the taking of
any action by the Company unless and only to the extent that (i) this Agreement
shall expressly provide therefor, (ii) such approval or consent shall be
required by non-waivable provisions of the Delaware Act or (iii) the Board shall
determine that obtaining such approval or consent would be appropriate or
desirable. The Members shall have no power to bind the Company.

         Section 4.2. Partition. Each Member waives, until termination of the
Company, any and all rights that such Member may have to maintain an action for

whether before or after the meeting. Neither the business to be transacted at,
nor the purpose of, any regular or special meeting of the Members need be
specified in a written waiver of notice. The attendance of any Member at a
meeting of Members shall constitute a waiver of notice of such meeting, except
when the Member attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business on the ground that
the meeting is not lawfully called or convened. Notice of any such meeting shall
be given to all Members not less than five (5) Business Days nor more than

on which notice of the meeting is given or the first such consent in respect of
the applicable action is executed and delivered to the Company, or, if notice is
waived, at the close of business on the day next preceding the day on which the
meeting is held. In the event that the action to be considered by the Members
shall have been determined by the Board to constitute a 


                                       28
<PAGE>   35
Sale (as defined in the Merger and Exchange Agreement) of the Company, MGI or
CERA Inc., solely for the purposes of determining the number of votes to which
each holder of record of Voting LLC Units shall be entitled in respect of any
action to be taken by the Members to approve such a Sale, such number of
Contingent LLC Units shall be deemed to be outstanding on the applicable record
date or day next preceding the day on which such notice is given or the first
such consent is so executed and delivered, as the case may be, and in such
names, as the Board shall determine would be issuable pursuant to Sections 1.3,

     Company, other than a Conversion Transaction;

         (ii)     the dissolution of the Company pursuant to Section 14.1(a);
     and

Member by proxy on all matters in which a Member is entitled to participate,
including waiving notice of any meeting, or voting or participating at a
meeting. Every proxy must be signed by the Member or such Member's
attorney-in-fact. No proxy shall be valid after the expiration of three years
from the date thereof unless otherwise provided in the proxy. Every proxy shall
be revocable at the pleasure of the Member executing it unless otherwise
provided in such proxy, such revocation shall 


                                       29
<PAGE>   36
not invalidate or otherwise affect actions taken under such proxy prior to such
revocation.

         (h) Organization. Each meeting of Members shall be conducted by the
Chairman or by such other Person as the Board may designate.

         (i) Action Without a Meeting. Unless otherwise provided in this

in writing, setting forth the action so taken, shall be signed by Members having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all Members entitled to vote were
present. Prompt notice of the taking of the action without a meeting by less
than unanimous written consent shall be given to those Members who have not
consented in writing.

         Section 4.5. Business Transactions of a Member with the Company. A
Member may lend money to, borrow money from, act as surety or endorser for,
guaranty or assume one or more specific obligations of, provide collateral for,
or transact any other business with the Company, provided that any such
transaction pursuant to any agreement entered into after the date hereof shall
be either (i) on terms not less favorable to the Company than those obtainable
from third parties or (ii) approved by a majority of Directors not affiliated
with, or related to, the interested Member.

         Section 4.6. No Cessation of Membership upon Bankruptcy. A Person shall
not cease to be a Member of the Company upon the happening, with respect to such
Person, of any of the events specified in section 18-304 of the Delaware Act.

<PAGE>   37

         (b) Voting Agreement.

consummation of the Transactions, the Directors will be [list names of initial
Directors], and Mr. Cribiore shall be the Chairman and Mr. Yergin shall be the
Vice Chairman. Except as provided in the preceding sentence, the Directors shall

naming or election, as the case may be, shall be deemed to have been designated
as a Manager 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 


                                       31
<PAGE>   38
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 Stanislaw shall be the CERA Nominees, Mr. David D. Nixon shall be the
MCM Nominee, Messrs. Cribiore, Gordon McMahon and Donald J. Gogel shall be the
Fund IV Nominees and Messrs. Peter Derow, Edward Jordan, Martin D. Payson,

and the Vice Chairman shall always be a CERA Nominee.

         (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 


                                       32

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.

waivers of notice of such meetings. Special meetings of the Board may be called
on 24 hours' notice, if notice is given to each Director personally or by
telephone or telegram, or on at least three days' notice, if notice is mailed to
each Director, addressed to him at his usual place of business. Notice of any
special meeting need not be given to any Director who attends such meeting
without protesting the lack of notice to him, prior to or at the commencement of
such meeting, or to any Director who submits a signed waiver of notice, whether
before or after such meeting, and any business may be transacted thereat.

the presence of a majority of the Directors then in office shall constitute a
quorum for the transaction of business and, except as otherwise provided in this
Agreement, the vote of a majority of the Directors present at any meeting at
which there is a quorum shall be the act of the Board. If a quorum shall not be
present at any meeting of the Board, the Directors present thereat may adjourn
the meeting to another time or place, without notice other than announcement at
the meeting, until a quorum shall be present. Any action required or permitted
to be taken at any meeting of the Board or of any committee thereof may be taken

committee designated by the Board, may participate in a meeting of the Board, or
any committee, by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and such participation in a meeting shall constitute presence in
person at the meeting.

designate one or more committees of the Board, which resolution shall specify
the duties, members and quorum requirements of such committee, each such
committee to consist of one or more of the Directors, provided that the
Consenting CERA Principal shall be entitled to be a member of any committee of
the Board having substantially the same powers as the Board or the Executive
Committee that has a member who is not an Independent Nominee. The Board may
designate one or more Directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member or alternate member of a committee,
the member or members thereof present at any meeting and not disqualified from
voting, whether or not such members constitute a quorum, may unanimously appoint
another member of the Board to act at the meeting in the place of any such
absent or disqualified member. Any such committee, to the extent provided in the
resolution of the Board, shall have and may exercise all the powers and
authority of the Board in the management of the property, business and affairs
of the Company, but no such committee shall have the power or authority to take
any action hereunder requiring (i) a vote greater than a majority of Directors
present as set forth in Section 5.4 or (ii) the consent or approval of the
Consenting CERA Principal or any one or more of the Fund IV Nominees, or

committees shall have such name or names as may be determined from time to time
by resolution adopted by the Board. Each committee shall keep regular minutes of
its meetings and report the same to the Board when required.

Executive Committee, which shall consist of the Chairman, the Consenting CERA
Principal, the CEO Nominee (if any), the MCM Nominee (if any) and such other
Directors as may be designated by the Board. During the intervals between
meetings of the Board, the Executive Committee shall have and may exercise all
the powers and authority of the Board in the management of the property,
business and affairs of the Company, except that the Executive Committee shall
not have the power or authority to take any action hereunder requiring (i) a
vote greater than a majority of Directors present as set forth in Section 5.4 or
(ii) the consent or approval of the Consenting CERA Principal or any one or more
of the Fund IV Nominees listed in Section 5.1(b)(iv) or authorizing any
distribution by the Company to Members.

         Section 5.8. Compensation of Directors. The Board shall have the
authority to fix the compensation of Directors. The Directors may be paid their
expenses, if any, of attendance at such meeting of the Board and may be paid a
fixed sum for attendance at each meeting of the Board or a stated salary as
Director. No such payment shall preclude any Director from serving the Company
in any other 


                                       36

his duties, be fully protected in relying in good faith upon the records of the
Company and upon information, opinions, reports or statements presented to the
Company by any of the Company's Officers or employees, or Committees designated
by the Board, or by any other person as to the matters the member reasonably
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.

         Section 5.10. Resignation. Any Director may resign at any time by
delivering a written notice of resignation to the Chief Executive Officer or the
Secretary. The resignation of any Director shall take effect upon receipt of
such notice or at such later time as shall be specified in the notice; and,
unless otherwise specified in the notice, the acceptance of the resignation by
the Company, the Members or the remaining Directors shall not be necessary to
make such resignation effective.

         Section 5.11. Directors as Agents. The Directors, to the extent of
their powers set forth in this Agreement, are agents of the Company for the
purpose of the Company's business, and the actions of the Directors taken in
accordance with such powers shall bind the Company. Except as otherwise provided
in this Agreement, no single Director shall have the power to bind the Company,

specified herein.

                                  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 


                                       42
<PAGE>   49
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.

         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 


                                       43
<PAGE>   50
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
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.


                                       44
<PAGE>   51
         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 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 


                                       45
<PAGE>   52
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 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 


                                       46
<PAGE>   53
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 


                                       47
<PAGE>   54
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 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 


                                       48
<PAGE>   55
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 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.


                                       49
<PAGE>   56
         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.

with the operation of the Company business in accordance with generally accepted
accounting principles consistently applied, and, to the extent inconsistent

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.

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 


                                       50
<PAGE>   57
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.

         (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 


                                       51
<PAGE>   58
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 by a
report of such accountants containing their opinion. The cost of such audits
will be an expense of the Company. A copy of any such audited financial
statements and accountant's report will be made available for inspection by the
Members.

         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 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.


                                       53
<PAGE>   60
         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
judgment 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 


                                       54
<PAGE>   61
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.

         (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


                                       55
<PAGE>   62
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.

         (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


                                       56
<PAGE>   63
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

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

         (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

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


                                       59
<PAGE>   66
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 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.

<PAGE>   67
         (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 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


                                       61
<PAGE>   68
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 contemplated 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, 


                                       62
<PAGE>   69
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 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


                                       63
<PAGE>   70
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).

         (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


                                       64
<PAGE>   71
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 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


                                       65
<PAGE>   72
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 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

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


                                       66
<PAGE>   73
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 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

                                       67


<PAGE>   74
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
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 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


                                       69
<PAGE>   76
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 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


                                       70
<PAGE>   77
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;

                  (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.

                    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.

         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;


                                       72
<PAGE>   79
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 winding
up of the Company's affairs has been completed, all of the assets of the Company
have been distributed and the Certificate has been canceled, all in accordance
with the Delaware Act.

         Section 14.4. Claims of the Members. The Members and former Members
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.

         RESTRICTIONS, HOLDBACK AND OTHER PROVISIONS OF THE AMENDED AND RESTATED

         CERTIFICATE NOR THE LLC UNITS REPRESENTED BY IT ARE ASSIGNABLE OR
         OTHERWISE TRANSFERABLE EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH
         LLC AGREEMENT, A COPY OF WHICH AGREEMENT IS ON FILE WITH THE SECRETARY

<PAGE>   82

         Each certificate representing LLC Units that are issued subsequent to
the date hereof (other than the Contingent LLC Units and LLC Units issued upon
exercise of the Contingent Options) shall bear a legend substantially to the
following effect in place of the legend set forth above:

         "THE LLC UNITS REPRESENTED HEREBY ARE ENTITLED TO THE BENEFITS OF AND
         ARE BOUND BY THE OBLIGATIONS, AND ARE SUBJECT TO THE TRANSFER

         ARE ON FILE WITH THE SECRETARY OF THE COMPANY."

         AN OPINION OF COUNSEL, WHICH OPINION AND COUNSEL SHALL BE REASONABLY
         SATISFACTORY TO THE COMPANY, TO THE EFFECT THAT SUCH DISPOSITION IS
         EXEMPT FROM THE PROVISIONS OF SECTION 5 OF SUCH ACT, OR (C) A NO-ACTION
         LETTER FROM THE SECURITIES AND EXCHANGE COMMISSION, REASONABLY
         SATISFACTORY TO COUNSEL FOR THE COMPANY, SHALL HAVE BEEN OBTAINED WITH

         THEREFROM."

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.

         In the event of any merger, consolidation, reorganization, exchange 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 February 12, 1998,
(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>   94
                  (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>   95
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>   96
         (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 re quested 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 determined, 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>   97
                  (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>   98
                  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>   99
         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>   100
                           (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>   101
         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>   102

         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>   103
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.

         (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>   105
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 amendment 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>   107
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 trans fer 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.


                                       15
<PAGE>   108
         (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>   109
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.

         Re:      Global Decisions Group LLC

Ladies and Gentlemen:

         We have acted as special Delaware counsel for Global Decisions Group
LLC, a Delaware limited liability company (the "Company"), in connection with
the matters set forth herein.

         For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of executed or
conformed counterparts, or copies otherwise proved to our satisfaction, of the
following:

         (a) The Certificate of Formation of the Company, dated as of June 30,
1997 (the "Certificate"), as filed in the office of the Secretary of State of
the State of Delaware (the "Secretary of State") on June 30, 1997;

         (b) The Limited Liability Company Agreement of the Company, dated as of
June 30, 1997;

         (c) The Registration Statement (the "Registration Statement") on Form
S-8 relating to limited liability company interests in the Company to be issued

Company with the Securities and Exchange Commission on February 12, 1998;

         (d) A form of Amended and Restated Limited Liability Company Agreement
of the Company, without exhibits (the "Agreement"), attached as an exhibit to
the Registration Statement;

         (e) A form of Cambridge Energy Research Associates, Inc. LLC Unit Grant
Agreement;

         (f) A form of Management LLC Unit Subscription Agreement relating to
the Cambridge Energy Research Associates, Inc. LLC Unit Option Plan;

         (g) A form of Management LLC Unit Subscription Agreement relating to
the MCM Group, Inc. LLC Unit Option Plan;

         (h) A form of Management LLC Unit Subscription Agreement relating to
the MCM Group, Inc. Stock Option Plan; and

         (i) A Certificate of Good Standing for the Company, dated February 12,
1998, obtained from the Secretary of State.

         Initially capitalized terms used herein and not otherwise defined are
used as defined in the Agreement. The documents listed in paragraphs (e) through
(h) above are hereinafter referred to each as an "LLC Unit Subscription
Agreement" and collectively as the "LLC Unit Subscription Agreements."

         For purposes of this opinion, we have not reviewed any documents other
than the documents listed in paragraphs (a) through (i) above. In particular, we
have not reviewed any document (other than the documents listed in paragraphs
(a) through (i) above) that is referred to in or incorporated by reference into
any document reviewed by us. We have assumed that there exists no provision in
any document that we have not reviewed that is inconsistent with the opinions
stated herein. We have conducted no independent factual investigation of our own
but rather have relied solely upon the foregoing documents, the statements and
information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

         With respect to all documents examined by us, we have assumed that (i)
all signatures on documents examined by us are genuine, (ii) all documents
submitted to us as originals are authentic, and (iii) all documents submitted to
us as copies conform with the original copies of those documents.

         For purposes of this opinion, we have assumed (i) that the Agreement
constitutes the entire agreement among the parties thereto with respect to the
subject matter

thereof, including with respect to the admission of members to, and the
creation, operation, management and termination of, the Company, and that the
Agreement and the Certificate are in full force and effect, have not been
amended and no amendment of the Agreement or the Certificate is pending or has
been proposed, (ii) that there are no proceedings pending or contemplated for
the merger, consolidation, conversion, liquidation, dissolution or termination
of the Company, (iii) except to the extent provided in paragraph 1 below, the
due organization or due formation, as the case may be, and valid existence in
good standing of each party to the documents examined by us under the laws of
the jurisdiction governing its organization or formation, (iv) the legal
capacity of natural persons who are signatories to the documents examined by us,
(v) that each of the parties to the documents examined by us has the power and
authority to execute and deliver, and to perform its obligations under, such
documents, (vi) the due authorization, execution and delivery by all parties
thereto (other than the Company) of all documents examined by us, including the
Agreement by each Person acquiring LLC Units pursuant to the LLC Unit
Subscription Agreements (each, a "Member" and collectively, the "Members"),
(vii) that the LLC Units are issued, transferred and paid for, and the Members
are admitted to the Company as members of the Company, all in accordance with
the Agreement, the LLC Unit Subscription Agreements and the Registration
Statement, (viii) that Schedule A to the Agreement, the Membership Register and
the books and records of the Company set forth all information required by the
Agreement and the Delaware Limited Liability Company Act (6 Del.C.
Section18-101, et seq.) (the "Act"), including all information with respect to
all Persons to be admitted as Members and their contributions to the Company,
and (ix) that the Members will not engage in tortious or wrongful conduct and
will fulfill all of their obligations as set forth in the Agreement and the LLC
Unit Subscription Agreements.

         We have not participated in the preparation of any offering material
relating to the Company (including the Registration Statement) and assume no
responsibility for the contents of any such material.

         This opinion is limited to the laws of the State of Delaware (excluding
the securities laws of the State of Delaware), and we have not considered and
express no opinion on the laws of any other jurisdiction, including federal laws
and rules and regulations relating thereto. Our opinions are rendered only with
respect to Delaware laws and rules, regulations and orders thereunder that are
currently in effect.

         Based upon the foregoing, and upon our examination of such questions of
law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

         1. The Company has been duly formed and is validly existing in good
standing as a limited liability company under the Act.
<PAGE>   4
  Global Decisions Group LLC
  February 12, 1998
  Page 4


         2. The LLC Units to be issued to the Members will be validly issued
and, subject to the qualifications set forth in paragraph 3 below, fully paid
and nonassessable limited liability company interests in the Company.

         3. A Member shall not be obligated personally for any of the debts,
obligations or liabilities of the Company, whether arising in contract, tort or
otherwise, solely by reason of being a member of the Company, except as a Member
may be obligated to make contributions to the Company and to repay any funds
wrongfully distributed to it.

         We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement. In giving the
foregoing consent, we do not thereby admit that we come within the category of
Persons whose consent is required under Section 7 of the Securities Act of 1933,
as amended, or the rules and regulations of the Securities and Exchange
Commission thereunder.

                                            Very truly yours,

                                            /s/ Richards, Layton & Finger, P.A.
