of incorporation and bylaws ("CHARTER DOCUMENTS") of CMG, in each case, as

reports and information statements required to be filed by each of them, which
returns, reports and statements are true, correct and complete in all material
respects, and paid all taxes required to be paid as shown on such returns,
reports and statements except for instances which would not have a material
adverse effect on CMG's Business Condition.  To the knowledge of CMG, all taxes
required to be paid in respect of the periods covered by such returns ("RETURN
PERIODS") have either been paid or fully accrued on the books of CMG except for
instances which would not have a material adverse effect on CMG's Business
Condition. To the knowledge of CMG, CMG and each of its Subsidiaries has fully
accrued all unpaid taxes in respect of all periods (or the portion of any such
periods) subsequent to the Return Periods except in instances which would not

instances which would not have a material adverse effect on CMG's Business
Condition.  To the knowledge of CMG, no deficiencies or adjustments for any tax
have been claimed, proposed or assessed, or threatened, except in instances
which would not have a material adverse effect on CMG's Business Condition.  To

years for which CMG's federal and state income tax returns, respectively, have
been audited and any years which are the subject of a pending audit by the
Internal Revenue Service and the applicable state agencies, except in instances
which would not have a material adverse effect on CMG's Business Condition.
Except as so disclosed, to the knowledge of CMG, CMG is not subject to any
pending or threatened, tax audit or examination and CMG has not waived any
statute of limitation with respect to the assessment of any tax, except in
instances which would not have a material adverse effect on CMG's Business
Condition.  To the knowledge of CMG, the CMG Financial Statements contain
adequate accruals for all unpaid taxes, except in instances which would not have
a material adverse effect on CMG's Business Condition.  For the purposes of this
Agreement, the terms "TAX" and "TAXES" will include all federal, state, local
and foreign taxes, assessments, duties, tariffs, registration fees, and other
governmental charges including without limitation all income, franchise,
property, production, sales, use, payroll, license, windfall profits, severance,
withholding, excise, gross receipts and other taxes, as well as any interest,
additions or penalties relating thereto and any interest in respect of such
additions or penalties.  To the knowledge of CMG, no consent or agreement has

            2.1.9.  ABSENCE OF CERTAIN CHANGES AND EVENTS.
                    -------------------------------------

     Since the filing date of CMG's last report with the SEC pursuant to the
reporting requirements of the Exchange Act, to the knowledge of CMG, none of the
following have occurred with respect to CMG which would be required to be
reported in a filing with the SEC:

                    2.1.9.1.  any damage, destruction or loss, whether or not
                              covered by insurance, materially and adversely
                              affecting the assets, properties, financial
                              condition, operating results, prospects or
                              business of CMG (as presently conducted and as
                              presently proposed to be conducted);

                    2.1.9.2.  any waiver by CMG of a valuable right or of a
                              material debt owed to it;

                    2.1.9.3.  any satisfaction or discharge of any lien, claim
                              or encumbrance or payment of any obligation by
                              CMG, except such a satisfaction, discharge or
                              payment made in the ordinary course of business
                              that is not material to the assets, properties,
                              financial condition, operating results or business
                              of CMG;

                    2.1.9.4.  any material change or amendment to a material
                              contract or arrangement by which CMG or any of its
                              assets or properties is bound or subject, except
                              for changes or amendments which are expressly
                              provided for or disclosed in this Agreement;

                    2.1.9.5.  any declaration of a dividend or other
                              distribution with respect to the capital stock of
                              CMG;

                    2.1.9.6.  any material change in any compensation
                              arrangement or agreement with any present or
                              prospective employee, contractor or director not
                              approved by CMG's board of directors and disclosed
                              to Microsoft; or

                    2.1.9.7.  any other event or condition of any character
                              which would materially and adversely affect the
                              assets, properties, financial condition, operating
                              results or business of CMG.

            2.2.4.  INVESTMENT CONSIDERATIONS.
                    -------------------------

                    2.2.4.1.  Microsoft is knowledgeable, sophisticated and
                              experienced in making, and is qualified to make,
                              decisions with respect to investments in shares
                              presenting an investment decision like that
                              involved in the purchase of the Purchased Shares,
                              including investments in securities issued by
                              companies comparable to CMG, and has requested,
                              received, reviewed and considered all information
                              it deems relevant in making an informed decision
                              to purchase the Purchased Shares.

                    2.2.4.2.  Microsoft is acquiring the number of Purchased
                              Shares set forth in Section 1.1 in the ordinary
                              course of its business and for its own account for
                              investment only and with no present intention of
                              distributing any of such Purchased Shares or any
                              arrangement or understanding with any other
                              persons regarding the distribution of such
                              Purchased Shares.

                    2.2.4.3.  Microsoft understands that the Purchased Shares
                              are "restricted securities" under the federal
                              securities laws inasmuch as they are being
                              acquired from CMG in a transaction not involving a
                              public offering and that under such laws and
                              applicable regulations such securities may be
                              resold without registration under the Securities
                              Act of 1933, as amended (the "Securities Act"),
                              only in certain limited circumstances. In this
                              connection Microsoft represents it is familiar
                              with SEC Rule 144, as presently in effect, and
                              understands the resale limitations imposed thereby
                              and by

                                       11
<PAGE>

                                the Securities Act.

                    2.2.4.4.    Microsoft will not, directly or indirectly,
                                offer, sell, pledge, transfer or otherwise
                                dispose of (or solicit any offers to buy,
                                purchase or otherwise acquire or take a pledge
                                of) any of the Purchased Shares except in
                                compliance with the Securities Act, and the
                                rules and regulations promulgated thereunder.

                    2.2.4.5.    Microsoft qualifies as an "accredited investor"
                                within the meaning of Rule 501 of Regulation D
                                promulgated under the Securities Act.

                    2.2.4.6.    It is understood that the certificates
                                evidencing the Purchased Shares will bear the
                                legend set forth below:

                                THE SECURITIES HAVE NOT BEEN
                                REGISTERED UNDER THE SECURITIES ACT OF
                                1933 MAY NOT BE SOLD, OFFERED FOR
                                SALE, PLEDGED OR HYPOTHECATED IN THE
                                ABSENCE OF A REGISTRATION STATEMENT IN
                                EFECT WITH RESPECT TO THE SECURITIES
                                UNDER THE ACT OR, IF REQUESTED BY CMG,
                                AN OPINION OF COUNSEL REASONABLY
                                SATISFACTORY TO CMG AND ITS COUNSEL,
                                THAT SUCH REGISTRATION IS NOT REQUIRED
                                UNDER SUCH ACT.

     The legend set forth above will be removed by CMG from any certificate
evidencing Purchased Shares upon delivery to CMG written verification that a
registration statement under the 1933 Act is at that time in effect with respect
to the legended security, an opinion by counsel, reasonably satisfactory to CMG
that such security can be freely transferred in a public sale without such a
registration statement being in effect, or verification, reasonably satisfactory
to CMG, that the Purchased Shares are being transferred in a transaction
permitted pursuant to Rule 144 or are exempt from Rule 144 pursuant to Rule
144(k).

                             3.  INVESTOR RIGHTS

     3.1.   TWELVE-MONTH HOLDING PERIOD.
            ---------------------------

     In consideration of the covenants herein, Microsoft agrees to not sell,
pledge, hypothecate or otherwise transfer any of the Purchased Shares prior to
the twelve- (12-) month anniversary of

                                       12

the closing of the Stock Purchase Agreement. Microsoft further agrees that the
certificates evidencing the Purchased Shares will bear the following legend:

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON
     TRANFER SET FORTH IN A STOCK PUCHASE AGREEMENT DATED DECEMBER 10, 1996 AND
     MAY NOT BE TRANSFERRED PRIOR TO ___________.

     3.2.   REGISTRATION RIGHTS.
            -------------------  

            3.2.1.  DEFINITIONS.
                    -----------

     For purposes of this Section 3.2:

                    3.2.1.1.    REGISTRATION.
                                ------------

     The terms "REGISTER," "REGISTERED," and "REGISTRATION" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Securities Act, and the declaration or ordering of
effectiveness of such registration statement.

                    3.2.1.2.    FORM S-3.
                                --------  

     The term "FORM S-3" means such form under the Securities Act as is in
effect on the date hereof or any successor registration form under the
Securities Act subsequently adopted by the SEC which permits inclusion or
incorporation of substantial information by reference to other documents filed
by CMG with the SEC.

                    3.2.1.3.    SEC.
                                ---         

     The term "SEC" or "COMMISSION" means the U.S. Securities and Exchange
Commission.

            3.2.2.  DEMAND REGISTRATION.
                    -------------------

                    3.2.2.1.    REQUEST BY HOLDERS.
                                ------------------  

     If CMG will receive at any time after the twelve- (12-) month anniversary
of the Closing Date, a written request from Microsoft that CMG file a
registration statement on Form S-3 for the registration of Purchased Shares
pursuant to this Section 3.2.2 specifying the number of Purchased Shares
proposed to be sold, then CMG will effect, as soon as practicable, the
registration under the Securities Act of all Purchased Shares which Microsoft
requests to be registered and included in such registration by written notice
given by Microsoft to CMG within twenty (20) calendar days after receipt of the
Request Notice, provided that the Purchased Shares requested by Microsoft to be
registered pursuant to such request must be at least fifty percent (50%) of the
Common Stock then owned by Microsoft and that CMG will not be obligated to
effect more than one such registration in any six- (6-) month period.

<PAGE>

                    3.2.2.2.    MAXIMUM NUMBER OF DEMAND REGISTRATIONS.
                                --------------------------------------  

     CMG is obligated to effect only two (2) such registrations pursuant to this
Section 3.2.2.

                    3.2.2.3.    DEFERRAL.
                                --------  

     If at the time of any request to register Shares pursuant to Section 3.2.2,
CMG is engaged or has fixed plans to engage within sixty (60) days of the date
of receipt of the request in a registered public offering, or is engaged in any
other activity which, in the good faith determination of CMG's Board of
Directors, would be adversely affected by the demand registration, then CMG may
at its option direct that such request be delayed for a period not in excess of
ninety (90) days from the closing of such offering or the date of CMG's Board of
Directors' determination, as the case may be.

            3.2.3.  PIGGYBACK REGISTRATIONS.
                    -----------------------

                    3.2.3.1.    NOTIFICATION.
                                ------------

     CMG will notify Microsoft in writing at least thirty (30) days prior to
filing any registration statement under the Securities Act for purposes of
effecting a public offering of securities of CMG (including, but not limited to,
registration statements relating to secondary offerings of securities of CMG,
but excluding registration statements relating to any registration under Section
3.2.2 or to any employee benefit plan or a corporate reorganization on Form S-8
or Form S-4, or their successors) and will afford Microsoft an opportunity to
include in such registration statement all or any part of the Purchased Shares
then held by Microsoft. Should Microsoft desire to include in any such
registration statement all or any part of the Purchased Shares held by
Microsoft, Microsoft will, within twenty (20) days after receipt of the above-
described notice from CMG, so notify CMG in writing, and in such notice will
inform CMG of the number of Purchased Shares Microsoft wishes to include in such
registration statement. If Microsoft decides not to include all of its Purchased
Shares in any registration statement thereafter filed by CMG, Microsoft will
nevertheless continue to have the right to include any Purchased Shares in any
subsequent registration statement or registration statements as may be filed by
CMG with respect to offerings of its securities, all upon the terms and
conditions set forth herein.

                    3.2.3.2.    DEFERRAL.
                                --------
  
     In connection with any offering under this Section 3.2.3 involving an
underwriting, if CMG will furnish to Microsoft, a certificate signed by the
President or Chief Executive Officer of CMG stating that in the good faith
judgment of the Board of Directors of CMG and in the opinion of the
underwriters, it would be seriously detrimental to CMG and its shareholders for
such registration statement to be filed and it is therefore essential to defer
the filing of such registration statement, then CMG will have the right to defer
such filing for a period of not more than 90 days

                                       14
<PAGE>

after receipt of the request of Microsoft; provided, however, that CMG may not
exercise this right more than once in any twelve- (12-) month period.

                    3.2.3.3.    UNDERWRITING.
                                ------------
  
     If a registration statement under which CMG gives notice under this Section
3.2.3 is for an underwritten offering, then CMG will so advise Microsoft. In
such event, the right of Microsoft to be included in a registration pursuant to
this Section 3.2.3 will be conditioned upon Microsoft's participation in such
underwriting and the inclusion of the Purchased Shares in the underwriting to
the extent provided herein. Should Microsoft propose to distribute its Purchased
Shares through such underwriting, it will enter into an underwriting agreement
in customary form with the managing underwriter or underwriter(s) selected for
such underwriting. Notwithstanding any other provision of this Agreement, if the
managing underwriter determine(s) in good faith that marketing factors require a
limitation of the number of shares to be underwritten, then the managing
underwriter(s) may exclude shares (including Purchased Shares) from the
registration and the underwriting, and the number of shares that may be included
in the registration and the underwriting will be allocated, first, to CMG, and
second, to Microsoft if Microsoft is requesting inclusion of its Purchased
Shares in such registration statement, provided however, that the right of the
underwriters to exclude shares (including Purchased Shares) from the
registration and underwriting as described above will be restricted so that the
number of Purchased Shares included in any such registration by Microsoft is not
reduced below fifteen (15%) of the shares included in the registration. If
Microsoft disapproves of the terms of any such underwriting, it may elect to
withdraw therefrom by written notice to CMG and the underwriter, delivered at
least ten (10) business days prior to the effective date of the registration
statement. Any Purchased Shares excluded or withdrawn from such underwriting
will be excluded and withdrawn from the registration.

                    3.2.3.4.    NO OTHER SECURITIES.
                                -------------------

     No other securities requested to be included in a registration pursuant to
this Section 3.2.3 for the account of anyone other than CMG or Microsoft will be
included in a registration unless either (i) all Purchased Shares requested by
Microsoft to be included in such registration are so included; or (ii) Microsoft
otherwise consents in writing.

                    3.2.3.5.    NOT DEMAND REGISTRATION.
                                -----------------------

     Registrations pursuant to this Section 3.2.3 will not be deemed to be
demand registrations as described in Section 3.2.2 above.

                                --------  

     All expenses incurred in connection with a registration pursuant to Section
3.2.2, or Section 3.2.2.3, including without limitation all registration and
qualification fees, printers' and

                                       15
<PAGE>

accounting fees, fees and disbursements of counsel for CMG, the underwriters and
Microsoft, (but excluding underwriters' and brokers' discounts and commissions),
will be borne by CMG. Microsoft, in a registration pursuant to Section 3.2.2 or
Section 3.2.3 will bear Microsoft's share of all discounts, commissions or other
amounts payable to underwriters or brokers in connection with such offering.
Notwithstanding the foregoing, CMG will not be required to pay for any expenses
of any registration proceeding begun pursuant to Section 3.2.2 if the
registration request is subsequently withdrawn at the request of Microsoft,
unless Microsoft agrees to forfeit their right to one (1) demand registration
pursuant to Section 3.2.2; provided, further, however, that if at the time of
such withdrawal, Microsoft has learned of a material adverse change in the
condition, business, or prospects of CMG not known to Microsoft at the time of
its request for such registration and have withdrawn their request for
registration with reasonable promptness after learning of such material adverse
change, then Microsoft will not be required to pay any of such expenses and will
retain its rights pursuant to Section 3.2.2.

                    3.2.4.2.    REGISTRATION.
                                ------------  

     Whenever required to effect the registration of any Purchased Shares under
Section 3.2.2, CMG will, as expeditiously as reasonably possible:

                         3.2.4.2.1.  Prepare and file with the SEC a
                                registration statement with respect to such
                                Purchased Shares and use its best efforts to
                                cause such registration statement to become
                                effective, and, upon the request of Microsoft,
                                keep such registration statement effective for
                                up to ninety (90) calendar days.

                         3.2.4.2.2.  Prepare and file with the SEC such
                                amendments and supplements to such registration
                                statement and the prospectus used in connection
                                with such registration statement as may be
                                necessary to comply with the provisions of the
                                Securities Act with respect to the disposition
                                of all securities covered by such registration
                                statement, which period will not be in excess of
                                nine (9) months from the effective date of such
                                registration statement.

                         3.2.4.2.3.  Furnish to Microsoft such number of copies
                                of a prospectus, including a preliminary
                                prospectus, in conformity with the requirements
                                of the Securities Act, and such other documents
                                as they may reasonably request in order to
                                facilitate the disposition of the Purchased
                                Shares owned by them that are included in such
                                registration.

                         3.2.4.2.4.  Register and qualify the securities covered
                                by such registration statement under such other
                                securities or Blue

                                writing by Microsoft, provided that CMG will not
                                be required in connection therewith or as a
                                condition thereto to qualify to do business or

                         3.2.4.2.5.  In the event of any underwritten public
                                offering, enter into and perform its obligations
                                under an underwriting agreement, in usual and
                                customary form, with the managing underwriter(s)
                                of such offering.

                         3.2.4.2.6.  Notify Microsoft at any time when a
                                prospectus relating thereto is required to be
                                delivered under the Securities Act of the
                                happening of any event as a result of which 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 not
                                misleading in the light of the circumstances
                                then existing.

                         3.2.4.2.7.  Furnish, at Microsoft's request, on the
                                date that Purchased Shares are delivered to the
                                underwriters for sale, if such securities are
                                being sold through underwriters, or, if such
                                securities are not being sold through
                                underwriters, on the date that the registration
                                statement with respect to such securities
                                becomes effective an opinion, dated as of such
                                date, of the counsel representing CMG for the
                                purposes of such registration, in form and
                                substance as is customarily given to
                                underwriters in an underwritten public offering
                                and reasonably satisfactory to Microsoft,
                                addressed to the underwriters, if any, and to
                                Microsoft.

                         3.2.4.2.8.  Use its best efforts to secure a "COMFORT"
                                letter dated as of such date, from the
                                independent certified public accountants of CMG,
                                in form and substance as is customarily given by
                                independent certified public accountants to
                                underwriters in an underwritten public offering
                                and reasonably satisfactory to Microsoft,
                                addressed to the underwriters, if any, and to
                                Microsoft.

            3.2.5.  FURNISH INFORMATION.
                    -------------------

     It will be a condition precedent to the obligations of CMG to take any
action pursuant to Section 3.2.2 or Section 3.2.2.3 that Microsoft will furnish
to CMG such information regarding

                                       17
<PAGE>

itself, its Purchased Shares held, and the intended method of disposition of
such securities as will be required to timely effect the registration of its
Purchased Shares.

            3.2.6.  INDEMNIFICATION.
                    ---------------

     In the event any Purchased Shares are included in a registration statement
under Section 3.2.2 or Section 3.2.3:

                    3.2.6.1.    BY CMG.
                                ------

     To the extent permitted by law, CMG will indemnify and hold harmless,
Microsoft, the officers and directors of Microsoft, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Securities Act, the 1934 Act or other federal or state law, insofar as
such losses, claims, damages, or liabilities (or actions in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations (collectively a "VIOLATION"):

                         3.2.6.1.1.  any untrue statement or alleged untrue
                                statement of a material fact contained in such
                                registration statement, including any
                                preliminary prospectus or final prospectus
                                contained therein or any amendments or
                                supplements thereto;

                         3.2.6.1.2.  the omission or alleged omission to state
                                therein a material fact required to be stated
                                therein, or necessary to make the statements
                                therein not misleading, or

                         3.2.6.1.3.  any violation or alleged violation by CMG
                                of the Securities Act, the 1934 Act, any federal
                                or state securities law or any role or
                                regulation promulgated under the Securities Act,
                                the 1934 Act or any federal or state securities
                                law in connection with the offering covered by
                                such registration statement;

and CMG will reimburse Microsoft, its officers or directors, for any legal or
other expenses reasonably incurred by them, as incurred, in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided however, that the indemnity agreement contained in this subsection
3.2.6.1 will not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of CMG (which consent will not be unreasonably withheld), nor will CMG be liable
in any such case for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by Microsoft, its officers, or
directors.

                    3.2.6.2.    BY MICROSOFT.
                                ------------

     To the extent permitted by law, Microsoft will indemnify and hold harmless
CMG, each of its directors, each of its officers who have signed the
registration statement, each person, if any, who controls CMG within the meaning
of the Securities Act, any underwriter and any other shareholder selling
securities under such registration statement or any of such other shareholder's
partners, directors or officers or any person who controls such shareholder
within the meaning of the Securities Act or the 1934 Act, against any losses,
claims, damages or liabilities (joint or several) to which CMG or any such
director, officer, controlling person, underwriter or other such shareholder,
partner or director, officer or controlling person of such other shareholder may
become subject under the Securities Act, the 1934 Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereto) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished by Microsoft expressly for
use in connection with such registration; and Microsoft will reimburse any legal
or other expenses reasonably incurred by CMG or any such director, officer,
controlling person, underwriter or other shareholder, partner, officer, director
or controlling person of such other shareholder in connection with investigating
or defending any such loss, claim, damage, liability or action; provided,
however, that the indemnity agreement contained in this subsection 3.2.6.2 will
not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of
Microsoft, which consent will not be unreasonably withheld; and provided
further, that the total amounts payable in indemnity by Microsoft under this
subsection 3.2.6.2 in respect of any Violation will not exceed the proceeds (net
of underwriters' and brokers' discounts and commissions) received by Microsoft
in the registered offering out of which such Violation arises.

                    3.2.6.3.    NOTICE.
                                ------

     Promptly after receipt by an indemnified party under this Section 3.2.6.3
of notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 3.2.6, deliver to the indemnifying
party a written notice of the commencement thereof and the indemnifying party
will have the right to participate in, and, to the extent the indemnifying party
so desires, jointly with any other indemnifying party similarly noticed, to
assume the defense thereof with counsel mutually satisfactory to the parties;
provided, however, that an indemnified party will have the right to retain its
own counsel, with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential conflict of
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, will relieve such
indemnifying party of any liability to the indemnified party under this Section
3.2.6, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 3.2.6. It is understood, however, that CMG
will, in connection with any one such action, suit or proceeding

                                       19
<PAGE>

or separate but substantially similar or related actions, suits, or proceedings
in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the reasonable fees and expenses of only one
separate firm of attorneys (in addition to any local counsel) at any time for
all such indemnified parties not having actual or potential differing interests
with CMG or among themselves.

                    3.2.6.4     CONTRIBUTION.
                                ------------

     In order to provide for just and equitable contribution to joint liability
under the Securities Act in any case in which either: (i) any shareholder,
including Microsoft (collectively "HOLDER") exercising rights under this
Agreement or another agreement providing similar rights, or any controlling
person of any such Holder, makes a claim for indemnification pursuant to this
Section 3.2.6 but it is judicially determined (by the entry of a final judgment
or decree by a court of competent jurisdiction and the expiration of time to
appeal or the denial of the last right of appeal) that such indemnification may
not be enforced in such case notwithstanding the fact that this Section 3.2.6
provides for indemnification in such case, or (ii) contribution under the
Securities Act may be required on the part of any such selling Holder or any
such controlling person in circumstances for which indemnification is provided
under this Section 3.2.6; then, and in each such case, CMG and such Holder will
contribute to the aggregate losses, claims, damages or liabilities to which they
may be subject (after contribution from others) in such proportion so that such
Holder is responsible for the portion represented by the percentage that the
public offering price of its Purchased Shares offered by and sold under the
registration statement bears to the public offering price of all securities
offered by and sold under such registration statement, and CMG and other selling
Holders are responsible for the remaining portion; provided, however, that, in
any such case, (A) no such Holder will be required to contribute any amount in
excess of the public offering price of all such Purchased Shares offered and
sold by such Holder pursuant to such registration statement; and (B) no person
or entity guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) will be entitled to contribution from any person or
entity who was not guilty of such fraudulent misrepresentation. CMG agrees to
require any other Holder participating as a selling shareholder to enter into an
agreement including provisions similar to this Section and will be solely
responsible for its failure to do so.

                    3.2.6.5.    SURVIVAL.
                                --------

     The obligations of CMG and Microsoft under this Section 3.2.6 will survive
the completion of any offering of Purchased Shares in a registration statement,
and otherwise.

            3.2.7.  TERMINATION OF CMG'S OBLIGATIONS.
                    --------------------------------

     CMG will have no obligations pursuant to Section 3.2.2 or Section 3.2.3
with respect to: (i) any request or requests for registration made by Microsoft
on a date more than three (3) years after the Closing Date; or (ii) any
Purchased Shares proposed to be sold by Microsoft in a registration pursuant to
Section 3.2.2 or Section 3.2.3 if, in the opinion of counsel to CMG, all such
Purchased Shares proposed to be sold by Microsoft may be sold in a three- (3-)
month period without registration under the Securities Act pursuant to Rule 144
under the Securities Act

                                       20
<PAGE>

without, in the judgment of Microsoft which will be concurred in writing by a
reputable investment banking firm selected by Microsoft, adversely affecting the
price at which the Purchased Shares may be sold.

     3.3.   SELL-BACK RIGHT.
            ---------------  

     The parties acknowledge and agree that Microsoft may wish to maintain its
ownership interest in CMG at a level lower than five percent (5%) of the total
equity of CMG and therefore agree as follows:

            3.3.1.  If for any reason, other than as a direct result of
                    purchases or other voluntary acquisitions of Purchased
                    Shares by Microsoft and its Subsidiaries, Microsoft and its
                    Subsidiaries owns or will own five percent (5%) or more of
                    the outstanding shares of the Common Stock,

                    3.3.1.1.    Microsoft will have the right to sell back and
                                CMG will be obligated to purchase that number of
                                shares of Common Stock at Current Market Value
                                (as defined below) as is necessary to reduce, or
                                in anticipation of a proposed action by CMG that
                                would result in increasing Microsoft's ownership
                                of Common Stock above five percent (5%) to
                                maintain Microsoft's beneficial ownership
                                interest below five percent (5%);

                    3.3.1.2.    In the event CMG does not have sufficient funds
                                to permit Microsoft to fully exercise its rights
                                under 3.3.1.1, or is restricted under applicable
                                corporate law from purchasing sufficient shares
                                of Common Stock (i) Microsoft will have the
                                right to sell, and CMG will be obligated to
                                purchase, the maximum number of shares of Common

     Microsoft agrees that, unless it has obtained the prior written consent of
CMG, it will not:

            4.2.1.  directly or indirectly (a) acquire beneficial ownership of
                    any Voting Stock, any securities convertible into or
                    exchangeable for Voting Stock, or any other right to acquire
                    Voting Stock (except, in any case, by way of stock dividends
                    or other distributions or offerings made available to
                    holders of any Voting Stock generally), (b) authorize or
                    make a tender, exchange or other offer which would result in
                    such an acquisition, or (c) engage in any solicitation of
                    proxies (within the meaning of the federal securities laws)
                    for the purpose of obtaining shareholder approval for any
                    transaction that would result in such an acquisition,
                    without (in any such case) the written consent of a majority
                    of CMG's Board of Directors (excluding directors, if any,
                    who are affiliated with Microsoft), if the effect of
                    such acquisition would be to increase the Voting Power of
                    all Voting Stock then beneficially owned by Microsoft, or
                    which Microsoft has a right to acquire, to an aggregate
                    number of shares exceeding the Maximum Percentage of the
                    total Voting Power of CMG at the time in effect; provided
                    that Microsoft will not be obligated to dispose of any
                    Voting Stock if the aggregate percentage of the total Voting
                    Power of CMG represented by Voting Stock beneficially owned
                    by Microsoft or which Microsoft has a right to acquire is

                    the date of this Agreement or any other action taken by CMG
                    or its affiliates. In the event that Microsoft owns in the
                    aggregate more than the Maximum Percentage of the total
                    Voting Power of CMG due to a repurchase by CMG of any of its
                    Common Stock, CMG will, at Microsoft's option, repurchase
                    that number of shares of its Common Stock from Microsoft
                    necessary to reduce Microsoft's ownership of CMG's Common
                    Stock below the Maximum Percentage, at the current market
                    price (provided, however, that the foregoing will not be
                    deemed to limit CMG's remedies in the event that the excess
                    Voting Stock were acquired in violation of this Section);

            4.2.2.  "SOLICIT" proxies with respect to Voting Stock under any

                    CONTEST" relating to the election of directors of CMG, as
                    such terms are defined in Regulation 14A under the Exchange

                    effect;

            4.2.3.  initiate, propose or otherwise solicit stockholders for the
                    approval of one or more stockholder proposals at any time,
                    or induce or attempt to induce any other person to initiate
                    any stockholder proposal; or
                   
            4.2.4.  take any action individually or jointly with any
                    partnership, limited partnership, syndicate, or other group
                    or assist any other person, corporation, entity or group in

                    propose a business combination or similar transaction with,
                    or a change of control of, CMG or to make a tender offer for
                    shares of CMG's Common Stock or other Voting Stock; or

            4.3.2.  directly or indirectly, without the prior approval of CMG's
                    Board of Directors, publicly (or in a manner requiring CMG
                    to disclose publicly) (i) propose any business combination
                    or similar transaction with, or a change of control of, CMG;
                    (ii) make or propose a tender offer for shares of Common
                    Stock or other Voting Stock of CMG; (iii) otherwise act to
                    seek control of or influence CMG's Board of Directors or the
                    management, policies or affairs of CMG; or (iv) propose any
                    amendment to or waiver under this Section which would permit
                    Microsoft to acquire additional Common Stock or other Voting

                    Section.

     4.4.   NOTICE OF PURCHASES.

     Without limiting the restrictions in Section 4.2 herein, Microsoft will
notify CMG as to Microsoft's acquisition of additional shares of Voting Stock,
or rights thereto within two (2) days after such acquisitions, regardless of
whether such transaction is otherwise required to be reported under law. Such
notice will be made by telecopy and U.S. mail in accordance with Section 8.3
herein.

     4.5.   NO VOTING ARRANGEMENTS.
            ----------------------

     Without CMG's prior written consent, Microsoft will not deposit any shares
of Voting Stock in a voting trust or subject any Voting Stock to any arrangement

     4.7.   RESTRICTIONS ON TRANSFERS.

Affiliate) any shares of CMG's capital stock that would represent at the time of
such transfer (and together with all prior such purchases) more than two percent
(2%) of the then issued and outstanding Voting Power of CMG's capital stock,
except for sales made in the public market in accordance with Rule 144 or sales
made pursuant to a registration statement filed by CMG under the Securities Act
of 1933, Microsoft agrees to first offer to sell such shares to CMG on the same
terms and conditions offered by such third party. If CMG does not complete the
purchase of such shares within ten (10) business days, then Microsoft may sell
such shares on the same terms and conditions for a period of thirty (30)
calendar days after the expiration of such ten-(10-) day period.

     4.8.   PROHIBITED TRANSFER.
            -------------------
     
     Any purchase which causes Microsoft to be in violation of the terms of
Section 4.2 above ("PROHIBITED TRANSFER") will not be affected by CMG and will
be voidable at the option of CMG by its giving written notice to the transferor,
the transferee and Microsoft. In the event of a Prohibited Transfer and without
limitation of the foregoing, CMG will (in addition to all other rights hereunder
and under law) have the option (but not the obligation) to purchase from
Microsoft up to that number of shares of Common Stock equal to the total number
of shares subject to the Prohibited Transfer upon the following conditions:

            4.8.1.  The price per share at which the shares are to be sold to
                    CMG will be equal to the price per share paid by Microsoft;
                    and
         
            4.8.2.  Such option will be exercisable by CMG for a period of sixty
                    (60) days after CMG has received notice or otherwise become
                    aware of the Prohibited Transfer by delivery by CMG to
                    Microsoft the full purchase price therefor, by certified
                    check or bank draft made payable to Microsoft. Upon such
                    delivery, CMG will cancel the number of shares of stock
                    purchased from Microsoft.

     4.9.   SUBSIDIARIES OF MICROSOFT.
            -------------------------

Voting Stock of CMG. Microsoft covenants to CMG that, if at

promulgated by the Commission, of any Common Stock or Voting Stock of CMG, or

practicable after such ownership, cause such Subsidiary to agree to be bound by
Section 4 of this Agreement.

     4.10.  EQUITABLE REMEDIES.
            ------------------

     Microsoft agrees that irreparable damage would occur if any provision of
this Section 4 were not performed in accordance with its specific terms or were
otherwise breached. It is accordingly agreed that CMG will be entitled to an
injunction or injunctions to prevent breaches of this Section 4 and to enforce

which it may be entitled at law or equity. Microsoft agrees to waive and hereby
waives any requirement for the securing or posting of any bond in connection
with the obtaining of any such injunctive or other equitable relief.

or transferees thereof, will bear the following legends:

counsel, and it will have received all such counterpart originals and certified
or other copies of such documents as they may reasonably request. Such documents
will include (but not be limited to) a copy of the resolutions of the Board of
Directors and, if required, the shareholders of CMG evidencing the approval of
this Agreement, the issuance of the Purchased Shares and the other matters
contemplated hereby.

     There will not be overtly threatened or pending any action, proceeding or
other application before any court or Government Entity brought by any person or
Governmental Entity (i) challenging or seeking to restrain or prohibit the
consummation of the transactions contemplated by this Agreement, or seeking to

limitations on Microsoft's ownership or the Purchased Shares, or to compel CMG
or Microsoft to dispose of or hold separate all or any material portion of CMG's
business or assets as a result of the transactions contemplated by the
Agreement, which in any event, in the reasonable judgment of Microsoft, will
probably have a material adverse effect on the Business Condition of CMG.
Further, there will not be threatened or pending any action, proceeding or other
application before any court or Governmental Entity brought by any Governmental
Entity or person which, in any event, in the reasonable judgment of Microsoft
will probably have a material adverse effect on the Business Condition of CMG.

     8.4.   SEVERABILITY.
            ------------

     If any provision of this Agreement is held to be unenforceable for any
reason, such provision and all other related provisions will be modified rather
than voided, if possible, in order to achieve the intent of the parties to this
Agreement to the extent possible. In any event, all other unrelated provisions
of this Agreement will be deemed valid and enforceable to the full extent.

     8.5.   SURVIVAL OF WARRANTIES.
            ----------------------

     All representations and warranties contained in this Agreement, including
the exhibits and schedules delivered pursuant to this Agreement, will not
survive the Closing, provided, however, that the representations and warranties
in Section 2.1.6 and Section 2.1.11 will survive until twenty (20) calendar days
after CMG has filed with the SEC its Form 10K Annual Report for the year ended
July 31, 1997.

     8.6.   ASSIGNMENT.
            ----------

     No party to this Agreement may assign, by operation of law or otherwise,
all or any portion of its rights, obligations, or liabilities under this
Agreement without the prior written consent of the other party to this
Agreement, which consent may be withheld in the absolute discretion of the party
asked to grant such consent. Any attempted assignment in violation of this
Section 8.6 will be voidable and will entitle the other party to this Agreement
to terminate this Agreement at its option.

     8.7.   COUNTERPARTS.
            ------------

     This Agreement may be executed in any number of counterparts and by
facsimile signatures, each of which will be deemed to be an original and all of
which together will be deemed to be one and the same instrument, it being
understood that all parties need not sign the same counterpart. All such
counterparts together will constitute but one agreement.

     8.8.   AMENDMENT.
            ---------

     This Agreement may not be amended except by an instrument in writing signed
on behalf of each of the parties hereto.

     8.9.   EXTENSION, WAIVER.
            -----------------

     At any time prior to the Closing, any party hereto may, to the extent
legally allowed, (i) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (ii) waive any
inaccuracies in the representations and warranties made to such party contained
herein or in any document delivered pursuant hereto, and (iii) waive compliance
with any of the agreements, covenants or conditions for the benefit of such
party contained herein. Any agreement on the part of a party hereto to any such
extension or waiver will be valid only if set forth in an instrument in writing
signed on behalf of such party.

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

     When a reference is made in this Agreement to Sections, Exhibits, or
Schedules, such reference will be to a Section, Exhibit, or Schedule to this
Agreement unless otherwise indicated. The words "include," "includes," and
"including" when used therein will be deemed in each case to be
followed by the words "without limitation." The table of contents, index
of defined terms, and headings contained in this Agreement are for reference
purposes only and will not affect in any way the meaning or interpretation of
this Agreement.

     8.11.  ARBITRATION.
            -----------

     The parties will endeavor to resolve all disputes by agreement and to that
end will each provide the other with sufficient descriptions and information
regarding its position to permit informed assessments and decisions. Any
disagreement, claim, demand, controversy, or dispute which arises after the
Closing (collectively "DISPUTE") in any way relating to this Agreement and the
performance or alleged breach by the parties, whether involving questions of law
or fact or both and regardless of the nature thereof or the remedy therefor,
which is not settled by agreement of the parties will be resolved pursuant to
the arbitration provisions in this Section. Any dispute between CMG and
Microsoft arising out of this Agreement, or any of the other agreements, to be
executed as a condition of the Closing, will be settled by final and binding
arbitration by three arbitrators, one selected by CMG, a second selected by
Microsoft, and a third arbitrator selected by the two other arbitrators. The
arbitration will take place in Seattle, Washington. The arbitration shall be
conducted in accordance with the rules and procedures established by the
American Arbitration Association. If any action or proceeding shall be commenced
to enforce this Agreement or any right arising in connection with this
Agreement, the prevailing party in such action or proceeding will be entitled to
recover from the other party, the reasonable attorneys' and arbitration fees,
costs and expenses incurred by such prevailing party in connection with such
action or proceeding, or negotiation. In addition, the prevailing party will be
entitled in such action or proceeding to recover from the other party reasonable
interest on any amounts awarded by the arbitral tribunal from the first day any
such amounts become payable to the prevailing party under this Agreement.

     8.12.  CONFIDENTIALITY.
            ---------------

     CMG and Microsoft agree to keep confidential and not to disclose any of the
terms and conditions of this Agreement, except to the extent such terms and
conditions otherwise become public through no fault of CMG or Microsoft, as
applicable, and to advise and require adherence by all of each of its officers,
directors, stockholders, employees, counsel, agents and representatives of this
obligation.

     8.13.  ATTORNEYS' FEES.
            ---------------

     If any action at law or in equity is necessary to enforce or interpret the
terms of this Agreement, the prevailing party will be entitled to recover its
reasonable attorneys' fees, experts'

                                       33
<PAGE>

fees and costs, including those for pretrial, trial, on appeal, in arbitration
and in bankruptcy and all other costs and necessary disbursements associated
with any such actions, in addition to any other relief to which such party may
be entitled.

     8.14.  THIRD PARTIES.
            -------------

     Nothing in this Agreement, express or implied, is intended to confer upon
any person, other than the parties hereto and their successors and assigns, any
rights or remedies under or by reason of this Agreement.

     8.15.  FURTHER ASSURANCES.
            ------------------

     From and after the date of this Agreement, upon the request of Microsoft or
CMG, CMG and Microsoft will execute and deliver such instruments, documents or
other writings as may be reasonably necessary or desirable to confirm and carry
out and to effectuate fully the intent and purposes of this Agreement.
