ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify directors and officers as well as other employees and
individuals against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with any threatened, pending or completed actions, suits or
proceedings in which such person is made a party by reason of such person being
or having been a director, officer, employee or agent to the Registrant. The
Delaware General Corporation Law provides that Section 145 is not exclusive of
other rights to which those seeking indemnification may be entitled under any
bylaw, agreement, vote of stockholders or disinterested directors or otherwise.
Section 6.1 of the Registrant's Bylaws provides for indemnification by the
Registrant of its directors, officers and employees to the fullest extent
permitted by the Delaware General Corporation Law.
 
     Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) for
unlawful payments of dividends or unlawful stock repurchases, redemptions or
other distributions, or (iv) for any transaction from which the director derived
an improper personal benefit. The Registrant's Certificate of Incorporation
provides for such limitation of liability.
 
     The Registrant intends to obtain directors, and officers, insurance
providing indemnification for certain of the Registrant's directors, officers
and employees for certain liabilities.
 
     Reference is also made to Section 7 of the Underwriting Agreement to be
filed as Exhibit 1.1 to the Registration Statement for information concerning
the underwriters' obligation to indemnify the Registrant and its officers and
directors in certain circumstances.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     On March 30, 1998, the Registrant issued 11,100,000 shares of its common
stock to IDG Enterprises, Inc., an indirect, wholly-owned subsidiary of
International Data Group, Inc., in return for all of the issued and
 
                                      II-1

outstanding capital stock of IDG Books Worldwide, Inc., a Massachusetts company

ITEM 17. UNDERTAKINGS
 
     (a) The undersigned hereby undertakes to provide to the underwriters at the
closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
     (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the provisions referenced in Item 14 of this
Registration Statement or otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act, and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered hereunder, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
     (c) The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Act, the
     information omitted from the form of prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act shall be deemed to be part of this Registration
     Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Act, each
     post-effective amendment that contains a form of prospectus 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.

        RE:    REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

        We have examined the Registration Statement on Form S-1 filed by you
with the Securities and Exchange Commission on May 22, 1998 (Registration No.
333-53433), as amended (the "Registration Statement"), in connection with the
registration under the Securities Act of 1933, as amended, of up to 3,657,000
shares of your Class A Common Stock (the "Shares"), including an over-allotment
option granted to the underwriters of the offering to purchase up to 477,000
shares. We understand that you are selling the Shares to the underwriters for
resale to the public as described in the Registration Statement. As your legal
counsel, we have examined the proceedings taken, and are familiar with the
proceedings proposed to be taken, by you in connection with the sale and
issuance of the Shares.

        It is our opinion that, upon completion of the proceedings being taken
or proposed to be taken by us, as your legal counsel, prior to the issuance of
the Shares, the Shares will be legally issued, fully paid and non-assessable
when sold in the manner described in the Registration Statement.

        We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and any amendments thereto.


                                    Very truly yours,

                                    WILSON SONSINI GOODRICH & ROSATI

                            IDG BOOKS WORLDWIDE, INC.

                            INDEMNIFICATION AGREEMENT


        This Indemnification Agreement ("Agreement") is made as of this ___ day
of ____, 1998, by and between IDG Books Worldwide, Inc., a Delaware corporation
(the "Company"), and _________________________ ("Indemnitee").

        WHEREAS the Company and Indemnitee recognize the increasing difficulty
in obtaining directors' and officers' liability insurance, the significant
increases in the cost of such insurance and the general reductions in the
coverage of such insurance;

        WHEREAS the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting officers and directors
to expensive litigation risks at the same time as the availability and coverage
of liability insurance has been severely limited; and

        WHEREAS the Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve as officers and directors of
the Company and to indemnify its officers and directors so as to provide them
with the maximum protection permitted by law.

        NOW, THEREFORE, in consideration for Indemnitee's services as an officer
or director of the Company, the Company and Indemnitee hereby agree as follows:

        1.     Indemnification.

               (a) Third Party Proceedings. The Company shall indemnify
Indemnitee if Indemnitee is or was a party or is threatened to be made a party
to any threatened, pending or completed action, suit, proceeding or any
alternative dispute resolution mechanism, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the
Company) by reason of the fact that Indemnitee is or was a director, officer,
employee or agent of the Company, or any subsidiary of the Company, by reason of
any action or inaction on the part of Indemnitee while an officer or director or
by reason of the fact that Indemnitee is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement (if
such settlement is approved in advance by the Company, which approval shall not
be unreasonably withheld) actually and reasonably incurred by Indemnitee in
connection with such action, suit or proceeding if Indemnitee acted in good
faith and in a manner Indemnitee 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 Indemnitee's conduct was
unlawful. 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 Indemnitee did not act in good
faith and in a manner which Indemnitee 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 Indemnitee's conduct
was unlawful.
<PAGE>   2
               (b) Proceedings By or in the Right of the Company. The Company
shall indemnify Indemnitee if Indemnitee was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the Company or any subsidiary of the Company to procure a judgment
in its favor by reason of the fact that Indemnitee is or was a director,
officer, employee or agent of the Company, or any subsidiary of the Company, by
reason of any action or inaction on the part of Indemnitee while an officer or
director or by reason of the fact that Indemnitee is or was serving at the
request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees) and, to the fullest extent permitted by
law, amounts paid in settlement actually and reasonably incurred by Indemnitee
in connection with the defense or settlement of such action or suit if
Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to
be in or not opposed to the best interests of the Company, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which Indemnitee shall have been adjudged to be liable to the Company unless and
only to the extent that the Court of Chancery of the State of Delaware 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, Indemnitee is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery of the State of Delaware or such other
court shall deem proper.

               (c) Mandatory Payment of Expenses. To the extent that Indemnitee
has been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Subsections (a) and (b) of this Section 1, or in
defense of any claim, issue or matter therein, Indemnitee shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
Indemnitee in connection therewith.

        2. Agreement to Serve. In consideration of the protection afforded by
this Agreement, if Indemnitee is a director of the Company he agrees to serve at
least for the six months after the effective date of this Agreement as a
director and not to resign voluntarily during such period without the written
consent of a majority of the Board of Directors. If Indemnitee is an officer of
the Company not serving under an employment contract, he agrees to serve in such
capacity at least for the balance of the current fiscal year of the Company and
not to resign voluntarily during such period without the written consent of a
majority of the Board of Directors. Following the applicable period set forth
above, Indemnitee agrees to continue to serve in such capacity at the will of
the Company (or under separate agreement, if such agreement exists) so long as
he is duly appointed or elected and qualified in accordance with the applicable
provisions of the Bylaws of the Company or any subsidiary of the Company or
until such time as he tenders his resignation in writing. Nothing contained in
this Agreement is intended to create in Indemnitee any right to continued
employment.

        3.     Expenses; Indemnification Procedure.

               (a) Advancement of Expenses. The Company shall advance all
expenses incurred by Indemnitee in connection with the investigation, defense,
settlement or appeal of any civil or criminal action, suit or proceeding
referenced in Section 1(a) or (b) hereof (but not amounts actually

                                       -2-

<PAGE>   3
paid in settlement of any such action, suit or proceeding). Indemnitee hereby
undertakes to repay such amounts advanced only if, and to the extent that, it
shall ultimately be determined that Indemnitee is not entitled to be indemnified
by the Company as authorized hereby. The advances to be made hereunder shall be
paid by the Company to Indemnitee within thirty (30) days following delivery of
a written request therefor by Indemnitee to the Company.

               (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a
condition precedent to his right to be indemnified under this Agreement, give
the Company notice in writing as soon as practicable of any claim made against
Indemnitee for which indemnification will or could be sought under this
Agreement. Notice to the Company shall be directed to the President of the
Company at the address shown on the signature page of this Agreement (or such
other address as the Company shall designate in writing to Indemnitee). Notice
shall be deemed received three business days after the date postmarked if sent
by domestic certified or registered mail, properly addressed, five business days
if sent by airmail to a country outside of North America; otherwise notice shall
be deemed received when such notice shall actually be received by the Company.
In addition, Indemnitee shall give the Company such information and cooperation
as it may reasonably require and as shall be within Indemnitee's power.

               (c) Procedure. Any indemnification and advances provided for in
Section 1 and this Section 3 shall be made no later than thirty (30) days after
receipt of the written request of Indemnitee. If a claim under this Agreement,
under any statute, or under any provision of the Company's Certificate of
Incorporation or Bylaws providing for indemnification, is not paid in full by
the Company within thirty (30) days after a written request for payment thereof
has first been received by the Company, Indemnitee may, but need not, at any
time thereafter bring an action against the Company to recover the unpaid amount
of the claim and, subject to Section 14 of this Agreement, Indemnitee shall also
be entitled to be paid for the expenses (including attorneys' fees) of bringing
such action. It shall be a defense to any such action (other than an action
brought to enforce a claim for expenses incurred in connection with any action,
suit or proceeding in advance of its final disposition) that Indemnitee has not
met the standards of conduct which make it permissible under applicable law for
the Company to indemnify Indemnitee for the amount claimed. However, Indemnitee
shall be entitled to receive interim payments of expenses pursuant to Subsection
3(a) unless and until such defense may be finally adjudicated by court order or
judgment from which no further right of appeal exists. It is the parties'
intention that if the Company contests Indemnitee's right to indemnification,
the question of Indemnitee's right to indemnification shall be for the court to
decide, and neither the failure of the Company (including its Board of
Directors, any committee or subgroup of the Board of Directors, independent
legal counsel, or its stockholders) to have made a determination that
indemnification of Indemnitee is proper in the circumstances because Indemnitee
has met the applicable standard of conduct required by applicable law, nor an
actual determination by the Company (including it Board of Directors, any
committee or subgroup of the Board of Directors, independent legal counsel, or
its stockholders) that Indemnitee has not met such applicable standard of
conduct, shall create a presumption that Indemnitee has or has not met the
applicable standard of conduct.

                                       -3-

<PAGE>   4
               (d) Notice to Insurers. If, at the time of the receipt of a
notice of a claim pursuant to Section 3(b) hereof, the Company has director and
officer liability insurance in effect, the Company shall give prompt notice of
the commencement of such proceeding to the insurers in accordance with the
procedures set forth in the respective policies. The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies.

               (e) Selection of Counsel. In the event the Company shall be
obligated under Section 3(a) hereof to pay the expenses of any proceeding
against Indemnitee, the Company, if appropriate, shall be entitled to assume the
defense of such proceeding, with counsel approved by Indemnitee, upon the
delivery to Indemnitee of written notice of its election to do so. After
delivery of such notice, approval of such counsel by Indemnitee and the
retention of such counsel by the Company, the Company will not be liable to
Indemnitee under this Agreement for any fees of counsel subsequently incurred by
Indemnitee with respect to the same proceeding, provided that (i) Indemnitee
shall have the right to employ his counsel in any such proceeding at
Indemnitee's expense; and (ii) if (A) the employment of counsel by Indemnitee
has been previously authorized by the Company, (B) Indemnitee shall have
reasonably concluded that there may be a conflict of interest between the
Company and Indemnitee in the conduct of any such defense, or (C) the Company
shall not, in fact, have employed counsel to assume the defense of such
proceeding, then the fees and expenses of Indemnitee's counsel shall be at the
expense of the Company.

        4.     Additional Indemnification Rights; Nonexclusivity.

               (a) Scope. Notwithstanding any other provision of this Agreement,
the Company hereby agrees to indemnify the Indemnitee to the fullest extent
permitted by law, notwithstanding that such indemnification is not specifically
authorized by the other provisions of this Agreement, the Company's Certificate
of Incorporation, the Company's Bylaws or by statute. In the event of any
change, after the date of this Agreement, in any applicable law, statute, or
rule which expands the right of a Delaware corporation to indemnify a member of
its board of directors or an officer, such changes shall be, ipso facto, within
the purview of Indemnitee's rights and Company's obligations, under this
Agreement. In the event of any change in any applicable law, statute or rule
which narrows the right of a Delaware corporation to indemnify a member of its
board of directors or an officer, such changes, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement shall have
no effect on this Agreement or the parties' rights and obligations hereunder.

               (b) Nonexclusivity. The indemnification provided by this
Agreement shall not be deemed exclusive of any rights to which Indemnitee may be
entitled under the Company's Certificate of Incorporation, its Bylaws, any
agreement, any vote of stockholders or disinterested Directors, the General
Corporation Law of the State of Delaware, or otherwise, both as to action in
Indemnitee's official capacity and as to action in another capacity while
holding such office. The indemnification provided under this Agreement shall
continue as to Indemnitee for any action taken or not taken

                                       -4-

<PAGE>   5
while serving in an indemnified capacity even though he may have ceased to serve
in such capacity at the time of any action, suit or other covered proceeding.

        5. Partial Indemnification. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of the expenses, judgments, fines or penalties actually or reasonably
incurred by him in the investigation, defense, appeal or settlement of any civil
or criminal action, suit or proceeding, but not, however, for the total amount
thereof, the Company shall nevertheless indemnify Indemnitee for the portion of
such expenses, judgments, fines or penalties to which Indemnitee is entitled.

        6. Mutual Acknowledgement. Both the Company and Indemnitee acknowledge
that in certain instances, Federal law or applicable public policy may prohibit
the Company from indemnifying its directors and officers under this Agreement or
otherwise. Indemnitee understands and acknowledges that the Company has
undertaken or may be required in the future to undertake with the Securities and
Exchange Commission to submit the question of indemnification to a court in
certain circumstances for a determination of the Company's right under public
policy to indemnify Indemnitee.

        7. Officer and Director Liability Insurance. The Company shall, from
time to time, make the good faith determination whether or not it is practicable
for the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the officers and directors of the
Company with coverage for losses from wrongful acts, or to ensure the Company's
performance of its indemnification obligations under this Agreement. Among other
considerations, the Company will weigh the costs of obtaining such insurance
coverage against the protection afforded by such coverage. In all policies of
director and officer liability insurance, Indemnitee shall be named as an
insured in such a manner as to provide Indemnitee the same rights and benefits
as are accorded to the most favorably insured of the Company's directors, if
Indemnitee is a director; or of the Company's officers, if Indemnitee is not a
director of the Company but is an officer. Notwithstanding the foregoing, the
Company shall have no obligation to obtain or maintain such insurance if the
Company determines in good faith that such insurance is not reasonably
available, if the premium costs for such insurance are disproportionate to the
amount of coverage provided, if the coverage provided by such insurance is
limited by exclusions so as to provide an insufficient benefit, or if Indemnitee
is covered by similar insurance maintained by a subsidiary or parent of the
Company.

        8. Severability. Nothing in this Agreement is intended to require or
shall be construed as requiring the Company to do or fail to do any act in
violation of applicable law. The Company's inability, pursuant to court order,
to perform its obligations under this Agreement shall not constitute a breach of
this Agreement. The provisions of this Agreement shall be severable as provided
in this Section 8. If this Agreement or any portion hereof shall be invalidated
on any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any applicable
portion of this Agreement that shall not have been invalidated, and the balance
of this Agreement not so invalidated shall be enforceable in accordance with its
terms.

                                       -5-

<PAGE>   6
        9. Exceptions. Any other provision herein to the contrary
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

               (a) Claims Initiated by Indemnitee. To indemnify or advance
expenses to Indemnitee with respect to proceedings or claims initiated or
brought voluntarily by Indemnitee and not by way of defense, except with respect
to proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law, but such indemnification or
advancement of expenses may be provided by the Company in specific cases if the
Board of Directors has approved the initiation or bringing of such suit; or

               (b) Lack of Good Faith. To indemnify Indemnitee for any expenses
incurred by the Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous; or

               (c) Insured Claims. To indemnify Indemnitee for expenses or
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes or penalties, and amounts paid in settlement) which
have been paid directly to Indemnitee by an insurance carrier under a policy of
officers' and directors' liability insurance maintained by the Company.

               (d) Claims Under Section 16(b). To indemnify Indemnitee for
expenses and the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of Section 16(b) of the Securities
Exchange Act of 1934, as amended, or any similar successor statute.

        10.    Construction of Certain Phrases.

               (a) For purposes of this Agreement, references to the "Company"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that if Indemnitee is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
Indemnitee shall stand in the same position under the provisions of this
Agreement with respect to the resulting or surviving corporation as Indemnitee
would have with respect to such constituent corporation if its separate
existence had continued.

               (b) For purposes of this Agreement, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on Indemnitee with respect to an employee
benefit plan; and references to "serving at the request of the Company" shall
include any service as a director, officer, employee or agent of the Company
which imposes duties on, or involves services by, such director, officer,
employee or agent with respect to an

                                       -6-

<PAGE>   7
employee benefit plan, its participants, or beneficiaries; and if Indemnitee
acted in good faith and in a manner Indemnitee reasonably believed to be in the
interest of the participants and beneficiaries of an employee benefit plan,
Indemnitee shall be deemed to have acted in a manner "not opposed to the best
interests of the Company" as referred to in this Agreement.

        11. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall constitute an original.

        12. Successors and Assigns. This Agreement shall be binding upon the
Company and its successors and assigns, and shall inure to the benefit of
Indemnitee and Indemnitee's estate, heirs, legal representatives and assigns.

        13. Attorneys' Fees. In the event that any action is instituted by
Indemnitee under this Agreement to enforce or interpret any of the terms hereof,
Indemnitee shall be entitled to be paid all court costs and expenses, including
reasonable attorneys' fees, incurred by Indemnitee with respect to such action,
unless as a part of such action, the court of competent jurisdiction determines
that each of the material assertions made by Indemnitee as a basis for such
action were not made in good faith or were frivolous. In the event of an action
instituted by or in the name of the Company under this Agreement or to enforce
or interpret any of the terms of this Agreement, Indemnitee shall be entitled to
be paid all court costs and expenses, including attorneys' fees, incurred by
Indemnitee in defense of such action (including with respect to Indemnitee's
counterclaims and cross-claims made in such action), unless as a part of such
action the court determines that each of Indemnitee's material defenses to such
action were made in bad faith or were frivolous.

        14. Notice. All notices, requests, demands and other communications
under this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and receipted for by the party addressee, on the date of such
receipt, or (ii) if mailed by domestic certified or registered mail with postage
prepaid, on the third business day after the date postmarked. Addresses for
notice to either party are as shown on the signature page of this Agreement, or
as subsequently modified by written notice.

        15. Consent to Jurisdiction. The Company and Indemnitee each hereby
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be brought only in the state courts of the State of Delaware.

        16. Choice of Law. This Agreement shall be governed by and its
provisions construed in accordance with the laws of the State of Delaware, as
applied to contracts between Delaware residents entered into and to be performed
entirely within Delaware without regard to the conflict of law principles
thereof.

        17. Period of Limitations. No legal action shall be brought and no cause
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs,

                                       -7-

<PAGE>   8
executors or personal or legal representatives after the expiration of two years
from the date of accrual of such cause of action, and any claim or cause of
action of the Company shall be extinguished and deemed released unless asserted
by the timely filing of a legal action within such two-year period; provided,
however, that if any shorter period of limitations is otherwise applicable to
any such cause of action, such shorter period shall govern.

        18. Subrogation. In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

        19. Amendment and Termination. No amendment, modification, termination
or cancellation of this Agreement shall be effective unless it is in writing
signed by both the parties hereto. No waiver of any of the provisions of this
Agreement shall be deemed or shall constitute a waiver of any other provisions
hereof (whether or not similar) nor shall such waiver constitute a continuing

so registered, as soon as practicable after any such request, or, in the event
of the failure or refusal of the Company so to register such Company Shares as

     (a) EXCLUSIVE BENEFIT. This Plan is created for the sole purpose of
providing benefits to the Participants and enabling them to share in the growth
of the Company, and is designed to invest primarily in Employer Securities.
Except as otherwise permitted by law, in no event shall any part of the
principal or income of the Trust be paid to or reinvested in any Employer or be
used for or diverted to any purpose whatsoever other than for the exclusive
benefit of the Participants and their beneficiaries.

     (b) RETURN OF CONTRIBUTIONS. Notwithstanding the foregoing provisions of
paragraph (a), any contribution made by an Employer to this Plan by a mistake of
fact may be returned to the Employer within one year after the payment of the
contribution; and any contribution made by an Employer that is conditioned upon
the deductibility of the contribution under Section 404 of the Code (each
contribution shall be presumed to be so conditioned unless the Employer
specifies otherwise) may be returned to the Employer if the deduction is
disallowed and the contribution is returned (to the extent disallowed) within
one year after the disallowance of the deduction.

     (c) PARTICIPANTS' RIGHTS. The establishment of this Plan shall not be
considered as giving any Employee, or any other person, any legal or equitable
right against any Employer, any Affiliate, the Plan Administrator, the Trustee
or the principal or the income of the Trust, except to the extent otherwise
provided by law. The establishment of this Plan shall not be considered as
giving any Employee, or any other person, the right to be retained in the employ
of any Employer or any Affiliate.

     (d) QUALIFIED PLAN. This Plan and the Trust are intended to qualify under
the Code as a tax-free employees' plan and trust, and particularly as an
employee stock ownership plan within the meaning of Section 4975(e)(7) of the
Code, and the provisions of this Plan and the Trust should be interpreted
accordingly.

the Agreement and Declaration of Trust shall control.

     (g) NONDISCRIMINATION. The Administrator shall not take any action or

<PAGE>   15

          (l) Claims for benefits under the Plan may be made by a Participant or
     a beneficiary of a Participant on forms supplied by the Plan Administrator.
     Written notice of the disposition of a claim shall be furnished to the
     claimant by the Administrator within ninety (90) days after the application
     is filed with the Administrator, unless special circumstances require an
     extension of time for processing, in which event action shall be taken as
     soon as possible, but not later than one hundred eighty (180) days after
     the application is filed with the Administrator; and in the event that no
     action has been taken within such ninety (90) or one hundred eighty (180)
     day period, the claim shall be deemed to be denied for the purposes of
     subparagraph (2). In the event that the claim is denied, the denial shall
     be written in a manner calculated to be understood by the claimant and
     shall include the specific reasons for the denial, specific references to
     pertinent Plan provisions on which the denial is based, a description of
     the material information, if any, necessary for the claimant to perfect the
     claim, an explanation of why such material information is necessary and an
     explanation of the claim review procedure.

          (2) If a claim is denied (either in the form of a written denial or by
     the failure of the Plan Administrator, within the required time period, to
     notify the claimant of the action taken), a claimant or his duly authorized
     representative shall have sixty (60) days after the receipt of such denial
     to petition the Plan Administrator in writing for a full and fair review of
     the denial, during which time the claimant or his duly authorized
     representative shall have the right to review pertinent documents and to
     submit issues and comments in writing. The Plan Administrator shall
     promptly review the claim and shall make a decision not later than sixty
     (60) days after receipt of the request for review, unless special
     circumstances require an extension of time for processing, in which event a
     decision shall be rendered as soon as possible, but not later than one
     hundred twenty (120) days after the receipt of the request for review. If
     such an extension is required because of special circumstances, written
     notice of the extension shall be furnished to the claimant prior to the
     commencement of the extension. The decision of the review shall be in
     writing and shall include specific reasons for the decision, written in a
     manner calculated to be understood by the claimant, with specific
     references to the Plan provisions on which the decision is based.

     (k) APPOINTMENT OF ADVISORS. The Administrator may appoint such
accountants, counsel (who may be counsel for an Employer), specialists and other
persons that it deems necessary and desirable in connection with the
administration of this Plan. The Administrator, by action of its Board of
Directors, may designate one or more of its employees to perform the duties
required of the Administrator hereunder.

                                    ARTICLE V

                          ELIGIBILITY AND PARTICIPATION

     (a) CURRENT PARTICIPANTS IN THE IDG ESOP. Any Employee of the Company on
the Transfer Date, who is then a Participant in the IDG ESOP, shall become a
Participant in this Plan as of the Effective Date of this Plan.

     (b) ELIGIBILITY AND PARTICIPATION. Thereafter, any other Employee of an
Employer shall become a Participant in the Plan upon completing one Hour of
Service for an Employer.

     (c) REHIRED PARTICIPANTS. An Employee who ceases to be a Participant and
who subsequently reenters the employ of an Employer shall again become a
Participant on the date of his reemployment.

     (d) FORMER EMPLOYEES. Any former Employee of the Company, whose termination
of employment occurred prior to the Transfer Date, but who continues to have an
account balance under the IDG ESOP, shall continue to have all the rights
provided to him under the IDG ESOP but shall not become a Participant of this
Plan unless and until he performs an Hour of Service for an Employer under this
Plan on or after the Transfer Date.

                                   ARTICLE VI

                           CONTRIBUTIONS TO THE TRUST

     (a) EMPLOYER CONTRIBUTIONS. The amount, if any, to be contributed to the
Trust by an Employer for each Plan Year shall be determined by its Board of
Directors.

          (1) It is the present intention of each Employer to make recurring and
     substantial contributions to the Trust for each Plan Year, but in no event
     shall such contribution for any corresponding taxable year of an Employer
     exceed the maximum amount deductible from the Employer's income for such
     taxable year under Section 404(a) of the Code.

          (2) Each Employer shall continue to have discretion as to the amount
     of its contributions, if any, in the event a loan used to purchase Employer
     Securities remains outstanding, even if failure to make a contribution
     places the ESOP in default on such loan.

     (b) FORM AND TIMING OF CONTRIBUTIONS. Payments on account of the
contributions due from an Employer for any Plan Year shall be made in cash,
qualifying employer real property, and/or Employer Securities. Such payments may
be made by a contributing Employer at any time, but payment of the contribution
for any Plan Year shall be completed on or before the time prescribed by 



                                      16.
<PAGE>   17

law, including extensions thereof, for filing such Employer's federal income tax
return for its corresponding taxable year.

     (c) VOLUNTARY CONTRIBUTIONS. The Administrator shall not accept any
voluntary Employee contributions designated by the Participant as nondeductible
Employee contributions (subject to the provisions of Code Section 72(e)).

     (d) NO DUTY TO INQUIRE. The Trustee shall have no right or duty to inquire
into the amount of any contribution made by an Employer or the method used in
determining the amount of any such contribution, or to collect the same, but the
Trustee shall be accountable only for funds actually received by it.


                                   ARTICLE VII

             PARTICIPANTS' ACCOUNTS AND ALLOCATION OF CONTRIBUTIONS

     (a) COMMON FUND. The assets of the Trust shall constitute a common fund in
which each Participant shall have an undivided interest.

     (b) ESTABLISHMENT OF ACCOUNTS. The Plan Administrator shall establish and
maintain with respect to each Participant at least two accounts, designated as
an Employer Securities Account and an Other Investments Account, that shall
reflect the Participant's interest in the Trust Fund with respect to
contributions made by his Employer. A Participant's Employer Securities Account
and Other Investments Account shall be deemed to be a single account for
purposes of determining forfeitures under paragraph (c)(3) of Article VIII.

     (c) SUSPENSE ACCOUNTS. The Plan Administrator shall establish and maintain
a suspense account to which shall be credited any units of Employer Securities
purchased by the Trustee with borrowed funds (such term including, for all
purposes of this Plan, purchase-money transactions). A separate suspense account
shall be maintained for each such purchase. The shares released from a suspense
account each year, if any, shall be allocated as of each Valuation Date to the
Participants' Employer Securities Accounts under the provisions of paragraph (e)
of this Article VII as Employer Securities attributable to Employer
contributions. The number of units of Employer Securities to be released from a
suspense account each Plan Year shall be determined under one of the following
methods, as selected by the Plan Administrator with respect to a particular
suspense account:

          (1) The number of units to be released for each Employer shall equal
     the number of units held in the suspense account immediately before the
     release for the current Plan Year multiplied by a fraction, the numerator
     of which is the amount of principal and interest paid by the Trustee on
     behalf of the Employer for the Plan Year with respect to the loan in
     question and the denominator of which is the sum of the amount of principal
     and interest paid on behalf of all Employers with respect to such loan for
     the current Plan Year plus the amount 



                                      17.
<PAGE>   18

     of principal and interest to be paid on behalf of all Employers with
     respect to such loan for all future Plan Years; or

          (2) The number of units to be released for each Employer shall equal
     the number of units held in the suspense account immediately before the
     release for the current Plan Year multiplied by a fraction, the numerator
     of which is the amount of principal paid by the Trustee on behalf of the
     Employer for the Plan Year with respect to the loan in question and the
     denominator of which is the sum of the amount of principal paid on behalf
     of all Employers with respect to such loan for the current Plan Year plus
     the amount of principal to be paid on behalf of all Employers with respect
     to such loan for all future Plan Years; provided, however, that:

               (A) The loan must provide for annual payments of principal and
          interest at a cumulative rate that is not less rapid at any time than
          level annual payments of such amounts for ten years (this requirement
          is not satisfied from the time that, by reason of a renewal, extension
          or refinancing, the sum of the expired duration of the loan, the
          renewal period, the extension period and the duration of a new exempt
          loan (used to refinance) exceeds ten years); and

               (B) Interest included in any repayment may be disregarded for
          release purposes only to the extent that it would be determined to be
          interest under standard loan amortization tables.

     (d) INTEREST OF PARTICIPANT. The interest of a Participant in the Trust
Fund shall be the combined balances remaining from time to time in his Employer
Securities Account and his Other Investments Account after making the
adjustments required in paragraph (e).

     (e) ADJUSTMENTS TO ACCOUNTS. Subject to the provisions of paragraph (f) the
Employer Securities Account and Other Investments Account of a Participant shall
be adjusted from time to time as follows:

          (1) STOCK DIVIDENDS. As of each Valuation Date, the Participant's
     Employer Securities Account shall be credited with any stock dividends for
     the Valuation Period ending with such current Valuation Date that are
     received on Employer Securities that are allocated to his Employer
     Securities Account (and that are not used, pursuant to paragraph (e)(6), to
     repay a loan).

          (2) EARNINGS FACTOR. As of each Valuation Date, the Participant's
     Other Investments Account shall be credited or charged, as the case may be,
     with a share of the Other Investments Account "earnings factor" for the
     Valuation Period ending with such current Valuation Date; provided,
     however, that such Participant was also a Participant as of the immediately
     preceding Valuation Date. The Other Investments Account earnings factor and
     a Participant's share thereof are to be determined as follows:



                                      18.
<PAGE>   19

               (A) The Other Investments Account earnings factor for any
          Valuation Period shall consist of

                    (i) the aggregate of the unrealized appreciation or
               depreciation occurring in the value of the portion of the Trust
               Fund invested in assets other than Employer Securities during
               such period that are attributable to contributions theretofore
               made by an Employer,

                    (ii) that portion of the income earned or the loss sustained
               by the portion of the Trust Fund invested in assets other than
               Employer Securities during such period (whether from investments
               or from the sale or exchange of assets) that are attributable to
               contributions theretofore made by an Employer,

                    (iii) cash dividends received on Employer Securities not
               allocated to any Participant's Employer Securities Account (to
               the extent such cash dividends are not used, pursuant to
               paragraph (e)(6), to repay a loan), and

                    (iv) cash dividends received on Employer Securities
               allocated to Participant's Employer Securities Accounts (to the
               extent such cash dividends are not used, pursuant to paragraph
               (e)(6), to repay a loan).

               (B) A Participant's share of the Other Investments Account
          earnings factor for any Valuation Period shall be that amount that
          shall bear the same ratio to such earnings factor as the balance in
          such Participant's Other Investments Account as of the end of the
          immediately preceding Valuation Period (less any amounts distributed
          from such Account to the Participant, or debited to such Account for
          any payments made with the assets of such Account for the purchase of
          Employer Securities, during the Valuation Period ending with the
          current Valuation Date) bears to the aggregate of the balances in the
          Other Investments Accounts as of the end of the immediately preceding
          Valuation Period of all Participants who are entitled to share in such
          earnings factor (less the aggregate amounts distributed from such
          Accounts to such Participants, or debited to such Accounts for any
          payments made with the assets of such Accounts for the purchase of
          Employer Securities, during the Valuation Period ending with the
          current Valuation Date).

               (C) Under no circumstances shall the Other Investments Account
          earnings factor, or a Participant's share thereof, include any
          appreciation, depreciation, income or loss attributable to the Plan's
          investment in Employer Securities.

          (3) EMPLOYER CONTRIBUTIONS AND FORFEITURES.

               (A) As of each Valuation Date, the Employer Securities Account of
          a Participant shall be credited with his allocable share of:



                                      19.
<PAGE>   20

                    (i) Employer Securities attributable to contributions by his
               Employer (including any Employer Securities that are released
               during such Plan Year from a suspense account maintained pursuant
               to paragraph (c));

                    (ii) Forfeitures of Employer Securities; and

                    (iii) Employer Securities purchased, directly or indirectly,
               with the assets of the Participant's Other Investments Account.

          The Employer Securities Account of a Participant shall be debited for
          any payments made with the assets of such Account for the purchase,
          directly or indirectly, of Employer Securities.

               (B) As of each Valuation Date, the Other Investments Account of a
          Participant shall be credited with his allocable share of

                    (i) contributions by his Employer in a form other than
               Employer Securities (except for Employer contributions used to
               pay principal or interest on any outstanding debts or liabilities
               incurred by the Trustee in connection with the purchase of
               Employer Securities); and

                    (ii) forfeitures of assets other than Employer Securities.

          The Other Investments Account of a Participant shall be debited for
          any payments made with the assets of such Account for the purchase,
          directly or indirectly, of Employer Securities.

               (C) The adjustments called for by sections (A) and (B) shall be
          made as follows:

                    (i) Each Employer's contributions, represented by Employer
               Securities and contributions of assets other than Employer
               Securities, shall be allocated, as of each Valuation Date that is
               the last day of a Plan Year, among the Employer Securities
               Accounts and the Other Investments Accounts, as the case may be,
               of the Participants employed by such Employer on the last day of
               the Plan Year (regardless of whether such Plan Year constitutes a
               Year of Service) based on the ratio that the Compensation of each
               Participant bears to the aggregate Compensation of all
               Participants employed by such Employer on the last day of the
               Plan Year. For each Plan Year in which this Plan is a Top Heavy
               Plan, a Participant who is employed by an Employer on the last
               day of such Plan Year and who is a Non-Key Employee shall be
               entitled to share in the contribution (as described in this
               subsection) to the extent such allocation, together with any
               amount allocated to the Non-Key Employee as a forfeiture 



                                      20.
<PAGE>   21

               pursuant to subsection (ii), does not exceed three percent (3%)
               of such Non-Key Employee's Section 415 Compensation (or, if less,
               the highest percentage of such Section 415 compensation allocated
               a Key Employee's Accounts hereunder, as well as the Key
               Employee's employer contribution accounts under any other defined
               contribution plan maintained by such Employer or an Affiliate,
               and including any Key Employee's elective contribution to any
               plan subject to Code Section 401(k)). To the extent provided in
               the previous sentence, such contribution shall be required
               regardless of whether the Non-Key Employee has completed a Year
               of Service. 

                    (ii) Forfeitures of Employer Securities and of assets other
               than Employer Securities occurring during a Plan Year (to the
               extent such forfeitures are not used to reinstate the account
               balances of reemployed Participants pursuant to paragraph (c)(4)
               of Article VIII) shall be allocated among the Employer Securities
               Accounts and the Other Investments Accounts, as the case may be,
               of all Participants in the Plan who are employed by any Employer
               on the last day of the Plan Year (regardless of whether such Plan
               Year constitutes a Year of Service) based on the ratio that the
               Compensation of each Participant bears to the aggregate
               Compensation of all Participants employed by all Employers on the
               last day of the Plan Year.

          (4) DISTRIBUTIONS. As of each Valuation Date, a Participant's Employer
     Securities Account and his Other Investments Account shall be charged with
     the amount of any distributions made to the Participant or his beneficiary
     from such Accounts pursuant to Article IX during the Valuation Period
     ending with the current Valuation Date.

          (5) TRANSFER FOR DIVERSIFICATION. In the event that a Participant
     elects to receive a diversification distribution from his Employer
     Securities Account pursuant to Article XI, the Participant's Employer
     Securities Account shall be charged with the amount of the Employer
     Securities that are distributed during the Valuation Period ending with the
     current Valuation Date.

          (6) DIVIDENDS. Dividends attributable to Employer Securities that are
     credited to Participants' Employer Securities Accounts, as well as to the
     suspense account established pursuant to paragraph (c) shall be used, to
     the extent required by the terms of the Agreement of Trust, to repay any
     loan used to purchase the Employer Securities on account of which the
     dividends were paid.

          (7) ACCOUNTING AND VALUATION METHODS. Except as otherwise required in
     any Agreement and Declaration of Trust, for purposes of all computations
     required by this Article VII, the accrual method of accounting shall be
     used, and the Trust Fund, each separate portion of the Trust Fund and the
     assets thereof shall be valued at their Fair Market Value as of each
     Valuation Date. Employer Securities shall be accounted for as provided in
     Treas. Reg. Section 1.402(a)-1(b)(2)(ii), as amended, or any successor
     regulation or statute.

          (8) ACCOUNTING PROCEDURES. The Plan Administrator may adopt such
     additional accounting procedures as are necessary to accurately reflect
     each Participant's interest in the Trust Fund or in any Fund, which
     procedures shall be effective upon approval by the Company. All such
     procedures shall be applied in a consistent, nondiscriminatory manner.

     (f) LIMITATION ON ANNUAL ADDITIONS.

          (1) Notwithstanding anything contained in this Plan to the contrary,
     the aggregate Annual Additions to a Participant's Accounts under this Plan
     and under any other defined contribution plans maintained by an Employer or
     an Affiliate for any Limitation Year shall not exceed the lesser of:

               (A) $30,000 (adjusted under such regulations as may be issued by
          the Secretary of the Treasury), or

               (B) 25% of the Participant's Section 415 Compensation for the
          Plan Year.

          (2) In the event that the Annual Additions, under the normal
     administration of the Plan, would otherwise exceed the limits set forth
     above for any Participant, or in the event that any Participant
     participates in both a defined benefit plan and a defined contribution plan
     maintained by any Employer or any Affiliate and the aggregate Annual
     Additions to and projected benefits under all of such plans, under the
     normal administration of such plans, would otherwise exceed the limits
     provided by law, then the Plan Administrator shall take such actions,
     applied in a uniform and nondiscriminatory manner, as will keep the Annual
     Additions and projected benefits for such Participant from exceeding the
     applicable limits provided by law. Excess Annual Additions shall be
     disposed of as provided in subparagraph (3). Adjustments shall be made to
     all other plans, if necessary to comply with such limits, before any
     adjustments shall be required to this Plan.

          (3) If as a result of the allocation of forfeitures, a reasonable
     error in estimating a Participant's Section 415 Compensation or other
     circumstances permitted under Section 415 of the Code, the Annual Additions
     attributable to Employer contributions for a particular Participant would
     cause the limitations set forth in this paragraph (f) to be exceeded, the
     excess amount shall be held unallocated in a suspense account for the
     Limitation Year and reallocated among the Participants as of the end of the
     next Plan Year to all of the Participants in the Plan in the same manner as
     an Employer contribution under the terms of paragraph (e) of this Article
     VII before any further Employer contributions are allocated to the Accounts
     of the Participants, and such allocations shall be treated as Annual
     Additions to the Accounts of the Participants. In the event that the limits
     on Annual Additions for any Participant would be exceeded before all of the
     amounts in the suspense account are allocated among the Participants, then
     such excess amounts shall be retained in the suspense account to be
     reallocated as of the end of the next Plan Year and any succeeding Plan
     Years until all amounts in the



                                      22.
<PAGE>   23

     suspense account are exhausted. The suspense account shall be credited or
     charged, as the case may be, with a share of the "earnings factor" for each
     Valuation Period during which it is in existence as if it were an Account
     of a Participant.

          (4) In the event that any Participant participates in both a defined
     benefit plan and a defined contribution plan maintained by his Employer or
     an Affiliate thereof, then, for Limitation Years beginning before January
     1, 2000, the sum of the Defined Benefit Plan Fraction and the Defined
     Contribution Plan Fraction for any Limitation Year shall not exceed 1.0.
     For these purposes,

               (A) The Defined Benefit Plan Fraction is a fraction, the
          numerator of which is the projected annual benefit of the Participant
          under the defined benefit plan determined as of the close of the
          Limitation Year and the denominator of which is the lesser of (1) the
          product of 1.25 times the dollar limitation in effect under Section
          415(b)(1)(A) of the Code for such Limitation Year or (2) the product
          of 1.4 times the amount that may be taken into account under Section
          415(b)(1)(B) of the Code with respect to such Participant for such
          Limitation Year.

               (B) The Defined Contribution Plan Fraction is a fraction, the
          numerator of which is the sum of the Annual Additions to the
          Participant's Accounts as of the close of the Limitation Year (less
          any amount that may be subtracted from the numerator so that the sum
          of the Defined Benefit Plan Fraction and the Defined Contribution Plan
          Fraction does not exceed 1.0 for the last Limitation Year beginning
          before January 1, 1983) and the denominator of which is the sum of the
          lesser of the following amounts determined for such year and for each
          prior Year of Service with the Employer: (1) the product of 1.25 times
          the dollar limitation in effect under Section 415(c)(1)(A) of the Code
          for such Limitation Year (determined without regard to Section
          415(c)(6) of the Code) or (2) the product of 1.4 times the amount that
          may be taken into account under Section 415(c)(1)(B) of the Code with
          respect to such Participant for such Limitation Year.

               (C) The figure "1.0" shall be substituted for the figure "1.25"
          set forth in sections (A) and (B) for each year in which this Plan is
          a Top Heavy Plan unless (1) the defined benefit plan provides a
          minimum benefit equal to 3% of each Participant's Compensation times
          the number of years (not exceeding 10) the Plan is a Top Heavy Plan or
          the defined contribution plan provides a minimum contribution equal to
          4% (7-1/2% if the Participant participates in both the defined benefit
          plan and the defined contribution plan) of each Participant's Section
          415 Compensation, and (2) the present value of the cumulative accrued
          benefits (not including rollover contributions made after December 31,
          1983) of the Key Employees for such year does not exceed 90% of the
          present value of the accrued benefits (not including rollover
          contributions made after December 31, 1983) under all plans. Such
          values shall be determined in the same manner as described in the "Top
          Heavy" definition in Article I.

               (D) At the election of the Administrator, the denominator under
          section (B) may be determined with respect to all Limitation Years
          ending before January 1, 1983, by multiplying (1) the denominator, as
          calculated under section (B) (as in effect for the Plan Year ending in
          1982), for the Limitation Year ending in 1982 by (2) the transition
          fraction. For these purposes, the term transition fraction' means a
          fraction with a numerator equal to the lesser of (1) $51,875 or (2)
          1.4 multiplied by 25% of the Compensation of the Participant for the
          Limitation Year ending in 1981 and with a denominator equal to the
          lesser of (1) $41,500 or (2) 25% of the Compensation of the
          Participant for the Plan Year ending in 1981. The transition fraction
          shall be applied by substituting the figure $41,500 for the figure
          $51,875 if this Plan is a Top Heavy Plan.


                                  ARTICLE VIII

                             BENEFITS UNDER THE PLAN

     (a) RETIREMENT BENEFIT.

          (1) A Participant shall be entitled to retire from the employ of his
     Employer upon such Participant's Early or Normal Retirement Date. Until a
     Participant actually retires from the employ of his Employer, no retirement
     benefits shall be payable to him, and he shall continue to be treated in
     all respects as a Participant; provided, however, that a Participant who
     attains age 70-1/2 shall begin receiving payment of his retirement benefit
     no later than the April 1 after the end of the calendar year in which he
     attains age 70-1/2 or retires, whichever is later; provided, further, that
     an Employee who is a 5% owner (as defined in Section 416 of the Code) shall
     begin receiving payment of his retirement benefit no later than the April 1
     after the end of the calendar year in which he attains age 70-1/2, even if
     he has not actually retired from the employ of his Employer at that time.
     Notwithstanding the preceding provisions of this subparagraph (1), nothing
     contained herein shall affect the Participants rights to begin receiving
     the benefit in accordance with the minimum distribution requirements under
     Section 401(a)(9) of the Code.

          (2) Upon the retirement of a Participant as provided in subparagraph
     (1), such Participant shall be entitled to a retirement benefit in an
     amount equal to 100% of the balance in his Accounts as of the Valuation
     Date immediately preceding or concurring with the date of his retirement
     reduced by any amount distributed subsequent to such Valuation Date and
     prior to the date of his retirement.

     (b) DISABILITY BENEFIT. In the event a Participant's employment with his
Employer is terminated by reason of his Disability and subject to adjustment as
provided in paragraph (e) of Article IX, such Participant shall be entitled to a
disability benefit in an amount equal to 100% of the balance in his Accounts as
of the Valuation Date immediately preceding or concurring with the date of the



                                      24.
<PAGE>   25

termination of his employment, reduced by any amount distributed subsequent to
such Valuation Date and prior to his termination of employment.

     (c) SEVERANCE OF EMPLOYMENT BENEFIT.

          (1) In the event a Participant's employment with his Employer is
     terminated for reasons other than retirement, Disability or death, and
     subject to adjustment as provided in paragraph (e) of Article IX, such
     Participant shall be entitled to a severance of employment benefit in an
     amount equal to his vested interest in the balance in his Accounts as of
     the Valuation Date immediately preceding or concurring with the date of the
     termination of his employment, reduced by any amount distributed subsequent
     to such Valuation Date and prior to his termination of employment.

          (2) (A) The vested interest in the Employer Securities Account and
          Other Investments Account of each Participant shall be a percentage of
          the balance of such Accounts as of the applicable Valuation Date,
          based upon such Participant's Years of Service as of the date of the
          termination of his employment, as follows:

          Notwithstanding the foregoing, on the Effective Date each Participant
          shall have a vesting percentage that is no less than his vesting
          percentage as of such date under the IDG ESOP.

               (B) Notwithstanding the provisions of subparagraph (2)(A), for
          any Plan Year in which this Plan is a Top Heavy Plan, the vested
          interest in the Employer Securities Account and Other Investments
          Account of each Participant performing at least one Hour of Service on
          or after the first day of such Plan Year shall be a percentage of the

          upon such Participant's Years of Service as of the date of the
          termination of his employment, as follows:

          being a Top Heavy Plan shall be treated as if it were an amendment to
          the Plan's vesting schedule for purposes of paragraphs (a)(3) and
          (a)(5) of Article XIV of this Plan.

               (D) Notwithstanding the foregoing, a Participant shall be 100%
          vested in his Employer Securities Account and Other Investments
          Account upon attaining his Early or Normal Retirement Date.

          (3)  (A) If the termination of employment results in five consecutive
          One Year Breaks in Service, then upon the occurrence of such five
          consecutive One Year Breaks in Service, the non-vested interest of the
          Participant in his Accounts as of the Valuation Date immediately
          preceding or concurring with the date of his termination of employment
          shall be deemed to be forfeited and such forfeited amount shall be
          reallocated, pursuant to the provisions of paragraph (e) of Article
          VII, at the end of the Plan Year concurring with the date the fifth
          such consecutive One Year Break in Service occurs. If the Participant
          is later reemployed by an Employer or an Affiliate, the unforfeited
          balance, if any, in his Employer Securities Account and Other
          Investments Account that has not been distributed to such Participant
          shall be set aside in separate accounts, and such Participant's Years
          of Service after any five consecutive One Year Breaks in Service
          resulting from such termination of employment shall not be taken into
          account for the purpose of determining the vested interest of such
          Participant in the balance of his Accounts that accrued before such
          five consecutive One Year Breaks in Service. If any portion of a
          Participant's Accounts is forfeited, his Employer Securities Account
          and his Other Investments Account shall be treated as a single account
          for purposes of this subparagraph and Employer Securities that were
          purchased with borrowed funds and allocated to such Participant's
          Employer Securities Account after release from a suspense account
          shall be forfeited only after all other assets in such Participant's
          Employer Securities and Other Investments Accounts. If interests in
          more than one class of Employer Securities have been so allocated to
          such Participant's Accounts, the Participant shall forfeit the same
          proportion of each such class. Except as otherwise required, whenever
          forfeitures are required for any Employer Securities the Participant
          shall forfeit specific Employer Securities on a last-in-first-out
          basis.

               (B) Notwithstanding any other provision of this paragraph (c), if
          a Participant is reemployed by an Employer or an Affiliate and, as a
          result, no five consecutive One Year Breaks in Service occur, the
          Participant shall not be entitled to any severance of employment
          benefit as a result of such termination of employment; provided,
          however, that nothing contained herein shall require or permit the
          Participant to return or otherwise have restored to his Accounts any
          funds distributed to him prior to his reemployment and the
          determination that no five consecutive One Year Breaks in Service
          would occur.

               (C) If a Participant is less than 100% vested in his Accounts and
          he receives all or a part of his severance of employment benefit,
          then, if the Participant resumes employment with an Employer or an
          Affiliate before the occurrence of five consecutive One Year Breaks in
          Service, until such time as there is a fifth consecutive One Year
          Break in Service, the Participant's vested portion of the balance in
          his Accounts at any time shall be equal to an amount ("X") determined
          by the formula X = P(AB + D) - D, where "P" is the vested percentage
          of the Participant at such time, "AB" is the balance in the
          Participant's Accounts at such time and "D" is the amount distributed
          as a severance of employment benefit.

<PAGE>   28

          (4)  (A) Notwithstanding any other provision of this paragraph (c), if
          at any time a Participant is less than 100% vested in his Accounts
          and, as a result of his severance of employment, he receives his
          entire vested severance of employment benefit pursuant to the
          provisions of Article IX, and the distribution of such benefit is made
          not later than the close of the fifth Plan Year following the Plan
          Year in which such termination occurs (or such longer period as may be
          permitted by the Secretary of the Treasury, through regulations or
          otherwise), then upon the occurrence of such distribution, the
          non-vested interest of the Participant in his Accounts shall be deemed
          to be forfeited and such forfeited amount shall be reallocated,
          pursuant to the provisions of paragraph (e) of Article VII, at the end
          of the Plan Year immediately following or concurring with the date
          such distribution occurs.

               (B) If a Participant is not vested as to any portion of his
          Employer Securities Account and Other Investments Account, he will be
          deemed to have received a distribution immediately following his
          severance of employment. Upon the occurrence of such deemed
          distribution, the nonvested interest of the Participant in his
          Employer Securities Account and Other Investments Account shall be
          deemed to be forfeited and such forfeited amount shall be reallocated,
          pursuant to the provisions of paragraph (e) of Article VII, at the end
          of the Plan Year immediately following or concurring with the date
          such distribution occurs.

               (C) If a Participant whose interest is forfeited under this
          subparagraph (4) is reemployed by an Employer or an Affiliate prior to
          the occurrence of five consecutive One Year Breaks in Service, then
          such Participant shall have the right to repay to the Trust, within
          five years after the Participant's resumption of employment, or, if
          earlier, no later than the date of completion of the Participant's
          fifth consecutive One Year Break in Service commencing after his
          distribution, the full amount of the severance of employment benefit
          previously distributed to him. A Participant who was subject to the
          provisions of section (B) and who is reemployed prior to the
          occurrence of five consecutive One Year Breaks in Service shall be
          deemed to have repaid his distribution as of the date of his
          reemployment by an Employer. If the Participant elects to repay (or is
          deemed to repay) such amount to the Trust within the time periods
          prescribed herein, the non-vested interest of the Participant
          previously forfeited pursuant to the provisions of section (A) shall
          be restored to the Accounts of the Participant, such restoration to be
          made from forfeitures of non-vested interests and, if necessary, by
          contributions of his Employer, so that the aggregate of the amounts
          repaid by the Participant and restored by the Employer shall not be
          less than the Accounts balance of the Participant at the time of
          forfeiture unadjusted by any subsequent gains or losses.



                                      28.

     (d) DEATH BENEFIT.

          (1) In the event of the death of a Participant and subject to
     adjustment as provided in paragraph (e) of Article IX, his beneficiary
     shall be entitled to a death benefit in an amount equal to 100% of the
     balance in his Accounts as of the Valuation Date immediately preceding or
     concurring with the date of his death, reduced by any amount distributed
     subsequent to such Valuation Date and prior to his date of death.

          (2) Subject to the provisions of subparagraph (3), at any time and
     from time to time, each Participant shall have the unrestricted right to
     designate a beneficiary to receive his death benefit and to revoke any such
     designation. Each designation or revocation shall be evidenced by written
     instrument signed by the Participant and filed with the Plan Administrator.
     In the event that a Participant has not designated a beneficiary or
     beneficiaries, or if for any reason such designation shall be legally
     ineffective, or if such beneficiary or beneficiaries shall predecease the
     Participant, then the Participant's surviving spouse, and if none, his
     issue, per stirpes, and if none, the personal representative of the estate
     of such Participant shall be deemed to be the beneficiary designated to
     receive such death benefit, or if no personal representative is appointed
     for the estate of such Participant, then his next of kin under the statute
     of descent and distribution of the state of such Participant's domicile at
     the date of his death shall be deemed to be the beneficiary or
     beneficiaries to receive such death benefit.

          (3) Notwithstanding the foregoing, if the Participant is married as of
     the date of his death, the Participant's surviving spouse shall be deemed
     to be his designated beneficiary and shall receive the full amount of the
     death benefit attributable to the Participant unless the spouse consents or
     has consented to the Participant's designation of another beneficiary. Any
     such consent to the designation of another beneficiary must acknowledge the
     effect of the consent, must be witnessed by a Plan representative or by a
     notary public and shall be effective only with respect to that spouse. A
     spouse's consent shall be a restricted consent (which may not be changed as
     to the beneficiary unless the spouse consents to such change in the manner
     described herein).


                                   ARTICLE IX

                              PAYMENTS OF BENEFITS

     (a)  (1) Except as otherwise provided under this Article IX, the amount of
     the benefit to which a Participant is entitled under paragraphs (a), (b) or
     (d) of Article VIII shall be paid to him (or, in the case of a death
     benefit, shall be paid to said Participant's beneficiary or beneficiaries)
     in accordance with one of the following options:

               (A) As a lump sum payment in cash as soon as practicable
          following the Participant's retirement, Disability (Social Security)
          or death, as the case may be; or



                                      29.
<PAGE>   30

               (B) If the aggregate vested interest in a Participant's Accounts
          exceeds $65,000, his benefit shall be paid to him in annual cash
          installments of $65,000 (or such lesser amount as may remain the
          Participant's vested Accounts for the final Plan Year in which an
          installment is paid); provided, however, that any amount that has not
          been distributed before the commencement of the eighth Plan Year
          following the first Plan Year in which distributions are made to the
          Participant shall be distributed as a final, ninth payment in such
          Plan Year; and provided, further, that any amount attributable to the
          Participant's Employer Securities Account and distributed as a final,
          ninth payment shall be paid to such Participant, to the extent
          possible, in units of Employer Securities, except that no fractional
          shares shall be issued and the value of any fractional shares to which
          a Participant would otherwise be entitled, as well as amounts
          attributable to any other Accounts, shall be paid in cash.
          Distributions made pursuant to this section B shall commence as soon
          as practicable following the Participant's retirement, Disability
          (Social Security) or death, as the case may be. Throughout the
          distribution period, the Trustee shall liquidate sufficient shares of
          Employer Securities annually to fund the installment payment for the
          Plan Year. The Trustee shall continue to invest the remainder of the
          Participant's vested Accounts in Employer Securities and such other
          investments as it shall determine to be appropriate.

          (2) Notwithstanding the foregoing, once a Participant reaches his
     Early Retirement Date, he may elect to receive his benefit as follows:

               (A) STANDARD EARLY RETIREMENT OPTION - Such amount shall be paid,
          beginning on the Participant's Early Retirement Date (Standard) (or,
          if later, the date that is three months following the date the
          Participant gave written notice to the Plan Administrator of his
          intention to take early retirement), in annual cash installments not
          exceeding $155,000, or such greater amount as may be permitted to be
          distributed without imposition of a penalty tax pursuant to Section
          4980A of the Code; provided, however, that any amount that has not
          been distributed before the date the Participant reaches age 59-1/2
          shall be distributed in cash in a lump sum as soon as practicable
          following the date the Participant reaches such age. The Trustee shall
          continue to invest the undistributed portion of the Participant's
          vested Accounts in Employer Securities and such other investments as
          it shall determine to be appropriate.

               (B) RULE OF 75 EARLY RETIREMENT OPTION - If the Participant's
          Account balance is less than or equal to $650,000, and he has reached
          his Early Retirement Date (Rule of 75), such amount shall be paid in
          annual installments of $65,000, subject to the limitations of this
          subparagraph. If the Participant's Account balance is greater than
          $650,000, and he has reached his Early Retirement Date (Rule of 75),
          such amount shall be paid in annual installments of 10% of his Account
          balance each year, subject to the limitations of this subparagraph;
          provided, however, that such Participant may elect to limit any given
          annual installment to $155,000 or such greater 



                                      30.
<PAGE>   31

          amount as may be permitted to be distributed without imposition of a
          penalty tax pursuant to Section 4980A of the Code.

                    (i) If the Participant elects to receive his benefit under
               one of the foregoing options, such installment shall be paid
               beginning on the Participant's Early Retirement Date (Rule of 75)
               (or, if later, the date that is three months following the date
               he gave written notice to the Plan Administrator of his intention
               to take early retirement).

                    (ii) Notwithstanding anything contained in this section (B)
               to the contrary, any amount that has not been distributed before
               the commencement of the eighth Plan Year following the first Plan
               Year in which distributions are made to the Participant shall be
               distributed as a final, ninth payment in such Plan Year.

          The Trustee shall continue to invest the undistributed portion of the
          Participant's vested Accounts in Employer Securities and such other
          investments as it shall determine to be appropriate.

     (b) Except as otherwise provided under this Article IX, the amount of the
Disability (Standard) benefit or the severance of employment benefit to which a
Participant is entitled under paragraph (c) of Article VIII, shall be paid to
him as follows:

          (1) If the aggregate vested interest in a Participant's Accounts does
     not exceed $5,000, his benefit shall be paid to him as a lump sum payment
     in cash as soon as practicable following the Participant's severance of
     employment or Disability (Standard).

          (2) If the aggregate vested interest in a Participant's Accounts
     exceeds $5,000 but does not exceed $65,000, his benefit shall be paid to
     him as a lump sum payment in cash, at the election of the Participant,
     either:

               (A) as soon as practicable following the Participant's severance
          of employment or Disability (Standard); or

               (B) as soon as practicable following the Participant's Early or
          Normal Retirement Date, whichever is earlier.

     Within a reasonable period of time after the Participant's severance of
     employment or Disability (Standard), the Plan Administrator shall provide
     the Participant with a form for the purpose of selecting a payment date
     under the foregoing provisions of this subparagraph (2). Accompanying such
     election form shall be a written explanation of the terms and conditions of
     the election. The Participant shall be permitted to submit his election to
     the Administrator in writing within a reasonable period after receiving
     notice from the Administrator. If the Participant fails during the election
     period to select either payment date, the Participant shall 



                                      31.
<PAGE>   32

     be deemed to have elected to receive his benefits as soon as practicable
     following his Normal Retirement Date, and such deemed election shall be
     irrevocable. If the Participant selects either payment date during the
     election period, his election shall be irrevocable.

          (3) If the aggregate vested interest in a Participant's Accounts
     exceeds $65,000, his benefit shall be paid to him in accordance with one of
     the following options:

               (A) Option A - Such amount shall be paid in annual cash
          installments of $65,000 (or such lesser amount as may remain the
          Participant's vested Accounts for the final Plan Year in which an
          installment is paid); provided, however, that any amount that has not
          been distributed before the commencement of the eighth Plan Year
          following the first Plan Year in which distributions are made to the
          Participant shall be distributed as a final, ninth payment in such
          Plan Year; and provided, further, that any amount attributable to the
          Participant's Employer Securities Account and distributed as a final,
          ninth payment shall be paid to such Participant, to the extent
          possible, in units of Employer Securities, except that no fractional
          shares shall be issued and the value of any fractional shares to which
          a Participant would otherwise be entitled, as well as amounts
          attributable to any other Accounts, shall be paid in cash.
          Distributions made pursuant to this Option A shall commence as soon as
          practicable following the Participant's severance of employment or
          Disability (Standard), as the case may be. Throughout the distribution
          period, the Trustee shall liquidate sufficient shares of Employer
          Securities annually to fund the installment payment for the Plan Year.
          The Trustee shall continue to invest the remainder of the
          Participant's vested Accounts in Employer Securities and such other
          investments as it shall determine to be appropriate.

               (B) Option B - Such amount shall be paid at the election of the
          Participant pursuant to the options outlined in paragraph (a) of this
          Article IX as either a lump sum payment or in annual cash
          installments, and such election may be made as soon as practicable
          following either the Participant's Early Retirement Date or his Normal
          Retirement Date.

               (C) Option C - If the Participant has reached his Early
          Retirement Date (Standard), such amount shall be paid in accordance
          with subparagraph (a)(1) of this Article IX.

               (D) Option D - If the Participant has reached his Early
          Retirement Date (Rule of 75), such amount shall be paid in accordance
          with subparagraph (a)(2) of this Article IX.

     Within a reasonable period of time after the Participant's severance of
     employment or Disability (Standard), the Plan Administrator shall provide
     the Participant with a form for the purpose of selecting one of the
     foregoing options. Accompanying such election form shall be a written
     explanation of the terms and conditions of the election. The Participant
     shall be permitted to submit his election to the Administrator in writing
     within a reasonable period after receiving 



                                      32.
<PAGE>   33

     notice from the Administrator. If the Participant fails during the election
     period to select an option, the Participant shall be deemed to have elected
     to receive his benefits under Option B, and such deemed election shall be
     irrevocable. If the Participant selects an option during the election
     period, his election shall be irrevocable.

          (4) In the event that the Participant's distribution of benefits is
     deferred pursuant to subparagraph (2) or (3), the portion of each vested
     Account balance of the Participant that is not needed to make annual
     payments during the then current Plan Year shall remain a part of the Trust
     Fund under Article VII. In the event of the Participant's death or
     Disability (Social Security), before receiving his entire vested Account
     balance, his remaining vested interest shall be paid to him (or, in the
     event of his death, to his beneficiary or beneficiaries) as a lump sum
     payment in cash as soon as practicable after notice is provided to the Plan
     Administrator of the Participant's Disability (Social Security) or death.
     In the event that the Participant has attained the age of 55 years and
     incurs a qualifying Hardship before receiving his entire vested Account
     balance, all or any portion of his remaining vested interest may be paid to
     him pursuant to paragraph (a) of Article X.

          (5) Any units of Employer Securities paid to the Participant pursuant
     to Option A described in subparagraph (3) shall be distributed subject to a
     requirement that such units be immediately resold to the Company. The
     Company shall purchase such units at their Fair Market Value as of the
     Valuation Date coincident with or most recently preceding the date of
     redemption. Payment of the purchase price shall be made by the Company, at
     the election of the Company, either in cash on the date of redemption or by
     an installment purchase. Any installment purchase shall provide for
     adequate security, a reasonable interest rate and a payment schedule
     providing for cumulative payments at any time not less than the payments
     that would be made if made in substantially equal annual installments
     beginning within 30 days and ending not more than five years after the date
     of redemption. The Plan shall have the right, at the discretion of the
     Trustee, to assume the rights and obligations of the Company to purchase
     any such Employer Securities.

     (c) Notwithstanding the foregoing, no distribution shall be made of any
Participant's benefit payable pursuant to paragraph (a), (b), or (c) of Article
VIII prior to his Normal Retirement Date unless the value of his benefit does
not exceed $5,000, or unless the Participant consents to the distribution. The
Plan Administrator shall provide each Participant entitled to a distribution of
more than $5,000 with a written notice of his rights, which shall include an
explanation of the alternative dates for distribution of benefits and the
optional forms of benefit available to the Participant. The Participant may
elect to exercise such rights, no less than 30 days and no more than 90 days
before the first date upon which distribution of the Participant's vested
account balances may be made; provided, however, that such distribution may
commence less than 30 days after the notice if the Plan Administrator clearly
informs the Participant that the Participant has a right to a period of at least
30 days after receiving the notice to consider the decision of whether or not to
elect a distribution (and, if applicable, a particular distribution option), and
if the Participant, after receiving the notice affirmatively elects a
distribution. In the event that a Participant does not consent to a distribution
of a benefit in excess of $5,000 to which he is entitled under paragraph (a),
(b) or (c) of Article VIII, the 



                                      33.
<PAGE>   34

amount of his benefit shall be paid to the Participant not later than sixty (60)
days after the last day of the Plan Year in which the Participant reaches his
Normal Retirement Date. In addition, payments under any of the options described
in paragraphs (a) and (b) shall satisfy the incidental death benefit
requirements and all other applicable provisions of Section 401(a)(9) of the
Code, the regulations issued thereunder (including Prop. Reg. Section
1.401(a)(9)-2), and such other rules thereunder as may be prescribed by the
Commissioner.

     (d) In no event shall the amount of the Participant's benefit payable
pursuant to Article VIII be paid later than the earlier of:

          (1) the 60th day after the last day of the Plan Year in which the
     Participant's employment is terminated as a result of his retirement,
     Disability or death or, if later, in which occurs the Participant's Normal
     Retirement Date; or

          (2) April 1 of the calendar year immediately following the calendar
     year in which he attains age 70-1/2 or retires, whichever is later;
     provided, however, that an Employee who is a 5% owner (as defined in
     Section 416 of the Code) shall begin receiving payment of his retirement
     benefit no later than the April 1 immediately following the calendar year
     in which he attains age 70-1/2, even if he has not actually retired from
     the employ of his Employer at that time. Notwithstanding the foregoing,
     nothing contained herein shall effect a Participant's right to begin
     receiving his benefit in accordance with the minimum distribution
     requirements under Section 401(a)(9) of the Code.

     (e) Notwithstanding the foregoing, payments under any of the options
described in paragraphs (a) and (b) of this Article IX shall satisfy the
requirements of Section 409(o) of the Code, the regulations issued thereunder
and such other rules thereunder as may be prescribed by the Commissioner, but
only with respect to stock acquired by the Plan after December 31, 1986, as
follows:

          (1) Payments of any benefit to which a Participant is entitled under
     paragraph (a) or (b) of Article VIII shall begin no later than one year
     after the close of the Plan Year in which the Participant retires or
     becomes Disabled.

          (2) Payment of any severance of employment benefit to which a
     Participant is entitled under paragraph (c) of Article VIII shall begin not
     later than one year after the close of the Plan Year in which the
     Participant incurs his fifth consecutive One Year Break in Service.

          (3) Payment of any benefit to which a Participant's beneficiary or
     beneficiaries are entitled under paragraph (d) of Article VIII shall begin
     not later than one year after the close of the Plan Year of the
     Participant's death.

          (4) Unless the Participant (or his beneficiary) elects otherwise,
     payments made under subparagraphs (1), (2) and (3) of this paragraph (e),
     during any Plan Year, shall not be 



                                      34.
<PAGE>   35

     less than the amount that would be paid if the Participant's vested
     Accounts were distributed in substantially equal periodic payments (not
     less frequently than annually) over a period not longer than the greater of

               (A) 5 years, or

               (B) in the case of a Participant with an account balance in
          excess of $500,000, five years plus one additional year (but not more
          than five additional years) for each $100,000 or fraction thereof by
          which such balance exceeds $500,000 (such amounts to be adjusted under
          such regulations as may be issued by the Secretary of the Treasury).

          (5) Notwithstanding the foregoing, any portion of a Participant's
     account attributable to shares of Employer Securities that were purchased
     with a loan described in Section 404(a)(9) of the Code, shall not be
     required to be distributed until the close of the Plan Year in which such
     loan is repaid in full.

     (f) PERIODIC ADJUSTMENTS. To the extent that the balance of a Participant's
Accounts has not been distributed and remains in the Plan, and notwithstanding
anything contained in the Plan to the contrary, the value of such remaining
balance shall be subject to adjustment from time to time pursuant to the
provisions of Article VII.

     (g) DIRECT ROLLOVER DISTRIBUTIONS. Notwithstanding any provision of the
Plan to the contrary, a Distributee may elect, at the time and in the manner
prescribed by the Plan Administrator, to have all or any portion of an Eligible
Rollover Distribution paid directly to an Eligible Retirement Plan specified by
the Distributee in a Direct Rollover. In the event that a Distributee elects to
have only a portion of an Eligible Rollover Distribution paid directly to an
Eligible Retirement Plan, the portion must not be valued at less than $500
(adjusted under such regulations as may be issued from time to time by the
Secretary of the Treasury).

     (h) NO DISTRIBUTIONS BEFORE OCTOBER 1, 1998. Notwithstanding the foregoing,
no distribution from this Plan shall be permitted during the period beginning
with the date shares of International Data Group, Inc. are converted into shares
of IDG Books Worldwide, Inc. and ending September 30, 1998.



                                      35.

                                    ARTICLE X

                        HARDSHIP DISTRIBUTIONS AND LOANS

     (a)  (1) A Participant who has attained the age of 55 years, has terminated
     his employment with his Employer for reasons other than retirement,
     Disability, or death, and whose vested benefits will be distributed
     pursuant to paragraph (b)(2)(B) or (b)(3) of Article IX, shall be eligible
     to receive an accelerated distribution on account of Hardship. Upon receipt
     of a request for a Hardship distribution, the Administrator shall determine
     whether an immediate and heavy financial need exists and the amount
     necessary to meet the need in a uniform and nondiscriminatory manner.

          (2) The determination of whether a Participant has an immediate and
     heavy financial need shall be made on the basis of all relative facts and
     circumstances. Each Participant requesting an accelerated distribution
     shall provide the Plan Administrator with a financial statement, in the
     form required by the Administrator.

          (3) If the Plan Administrator determines that the Participant is
     entitled to an accelerated distribution pursuant to this paragraph (a), the
     portion of the Participant's remaining vested benefit determined to be
     necessary to satisfy his financial need shall be paid to the Participant as
     soon as practicable after the existence of a Hardship has been determined.
     The Participant's remaining vested benefit, if any, shall be distributed in
     accordance with the terms of paragraphs (b)(2)(B) and (b)(3) of Article IX.

          (4) The Plan Administrator shall not make any distribution to a
     Participant on account of Hardship unless such Participant has terminated
     his employment with his Employer and has met all other requirements of this
     paragraph (a).

     (b)  (1) Upon application of a Participant who is actively employed by an
     Employer, based on Hardship, the Plan Administrator, in accordance with its
     uniform nondiscriminatory policy, may direct the Trustee to make a loan to
     the Participant.

               (A) The Administrator, in its absolute discretion, shall
          determine whether such Participant has incurred a Hardship (as defined
          in paragraph (y) of Article I) and shall determine the amount of such
          Hardship loan, pursuant to the terms of this paragraph (b); provided,
          however, that no loan shall be approved in an amount less than $1,000.

               (B) Until otherwise directed by the Administrator, the Company's
          Benefits Manager shall be designated as the person authorized to
          administer the loan program set forth herein. Applications shall be
          submitted to such person on forms obtained from such person.

          (2) The amount advanced may not exceed the lesser of:



                                      36.
<PAGE>   37

               (A) $50,000, reduced by the excess, if any, of:

                    (i) the Participant's highest aggregate outstanding balance
               of all loans from the Plan during the 12-month period ending on
               the day before the date on which the loan is made, over

                    (ii) the aggregate outstanding balance of all loans from the
               Plan on the date on which the loan is made; or

               (B) 50% of the vested balance of the Participant's Employer
          Securities Account and Other Investments Account.

     Notwithstanding the foregoing, no Participant shall be entitled to borrow
     an amount that the Plan Administrator determines could not be adequately
     secured by the portion of such Participant's Accounts that is permitted to
     be held as security pursuant to applicable Department of Labor Regulations.

          (3) TIME AND MANNER OF REPAYMENT. Any loan made under this paragraph
     (b) shall be repayable to the Trust at such times and in such manner as may
     be provided by the Administrator, subject to the following limitations:

               (A) Each loan shall be secured by 50% of the vested interest of
          the Participant in his Accounts. The Administrator shall not accept
          any other form of security. Each Participant shall agree to have each
          required loan payment deducted from his pay and remitted to the
          Trustee.

               (B) Each loan shall bear interest at a reasonable rate and shall
          provide for substantially level amortization of principal and interest
          no less frequently than quarterly. The interest rate charged shall be
          comparable to the rate charged by the Bank of Boston (or a similar
          institution selected by the Plan Administrator) for comparable loans
          as determined at the time the loan is approved by the Plan
          Administrator.

               (C) Each loan shall be repaid within a specified period of time
          not to exceed five (5) years, unless used to acquire the principal
          residence of the Participant.

               (D) Each Participant shall agree that, notwithstanding any other
          provision of his loan agreement, all outstanding principal and
          interest attributable to his loan will become immediately due and
          payable as of the date of commencement of his distribution of
          benefits.

          (4) DEFAULT. If the loan is not paid on the due date, the Trustee, at
     the direction of the Administrator, may proceed to collect said loan with
     any legal remedy available, including reducing the amount of any
     distribution permitted under Article VIII by the amount of any such loan
     that may be due and owing as of the date of distribution or any other
     action that may be permitted by law.

          (5) PRIOR LOANS. Notwithstanding the foregoing, this Amendment and
     Restatement, in and of itself, does not require the early repayment of any
     loan outstanding and not otherwise due on the date of this Amendment and
     Restatement.

                                   ARTICLE XI

                          DIVERSIFICATION DISTRIBUTIONS

     (a) DIVERSIFICATION DISTRIBUTIONS (REQUIRED) . For Plan Years beginning
after December 31, 1986 and with respect to Employer Securities acquired after
December 31, 1986, any Participant who has attained age 55 and completed ten
(10) years of participation in the Plan (disregarding any years of participation
beginning prior to January 1, 1986) shall have the right to direct the Trustee
to distribute a portion of his Employer Securities Account before his
retirement, death, Disability, or severance of employment as a diversification
distribution.

          (1) Such a Participant may elect, within ninety (90) days after the
     close of the first Plan Year in the Diversification Election Period
     (Required), to receive a distribution of cash in an amount not exceeding
     25% of the portion of the balance of his Employer Securities Account
     attributable to Employer Securities acquired by, or contributed to, the
     Plan after December 31, 1986, determined as of the last day of such Plan
     Year.

          (2) Within ninety (90) days after the close of the second, third,
     fourth and fifth Plan Years in the Diversification Election Period
     (Required), such a Participant may elect to receive a distribution of cash
     in an amount equal to the difference between

               (A) 25% of the portion of the balance of his Employer Securities
          Account attributable to Employer Securities acquired by, or
          contributed to, the Plan after December 31, 1986, determined as of the
          last day of such Plan Year, and

               (B) the amount with respect to which a diversification
          distribution was previously elected;

          (3) In the final Plan Year of the Diversification Election Period
     (Required), the Participant may elect to receive a distribution in cash in
     an amount equal to the difference between



                                      38.
<PAGE>   39

               (A) 50% of the portion of the balance of his Employer Securities
          Account attributable to Employer Securities acquired by, or
          contributed to, the Plan after December 31, 1986, determined as of the
          last day of such Plan Year, and

               (B) the amount with respect to which a diversification
          distribution was previously elected.

          (4) Notwithstanding the foregoing, if the annual valuation of Employer
     Securities has not been made by the close of any Plan Year in the
     Diversification Election Period (Required), the applicable ninety (90) day
     election period shall not close until ninety (90) days after such valuation
     has been made.

          (5) If any Participant elects to receive a diversification
     distribution in any year in the Diversification Election Period (Required),
     the Trustee shall sell Employer Securities that are allocated to the
     Account of the Participant with a value equal to the amount to be
     distributed. The proceeds of such sale shall be distributed to the
     Participant no later than ninety (90) days after the Participant's election
     is made.

     (b) DIVERSIFICATION DISTRIBUTIONS (IDG BOOKS). For Plan Years ending no
earlier than ninety (90) days before the Internal Revenue Service issues a
determination letter with respect to the tax qualified status of this Plan, any
Participant whose attained age and years of participation in the Plan total 60
or more shall have the right to direct the Trustee to distribute a portion of
his Employer Securities Account before his retirement, death, Disability, or
severance of employment as a diversification distribution.

          (1) Such a Participant may elect, within ninety (90) days after the
     close of each Plan Year in the Diversification Election Period (IDG Books),
     to make a diversification election of an amount not exceeding the lesser of
     $65,000 or 10% of his Employer Securities Account, determined as of the
     last day of such Plan Year. 

          (2) If a Participant makes a diversification election under this
     paragraph (b) of Article XI, the Trustee shall transfer the amount elected
     by the Participant in subparagraph (1) to the International Data Group
     401(k) Plan.

          (3) Notwithstanding the foregoing, if the annual valuation of Employer
     Securities has not been made by the close of any Plan Year in the
     Diversification Election Period (IDG Books), the applicable ninety (90) day
     election period shall not close until ninety (90) days after such valuation
     has been made.

          (4) If any Participant elects to make a diversification election in
     any year in the Diversification Election Period (IDG Books), the Trustee
     shall sell Employer Securities that are allocated to the Account of the
     Participant with a value equal to the amount to be transferred to the
     International Data Group 401(k) Plan. The proceeds of such sale shall be
     diversified on behalf of the Participant no later than ninety (90) days
     after the Participant's election is made.

     (c) ELECTION. An eligible Participant's diversification election shall be
made in writing on such forms as may be approved by the Plan Administrator, with
the Participant's designating the amount to be distributed as a percentage of
the portion of his Employer Securities Account that is available for
distribution as described in paragraphs (a) and (b).

     (d) MINIMUM DISTRIBUTION. Notwithstanding any other provision of this
Article XI, no diversification distribution shall be made to any Participant
unless the value of the Employer Securities acquired by or contributed to this
Plan, and allocated to the Participant's Employer Securities Account, exceeds
$500 as of the Valuation Date immediately preceding the first day on which the
Participant may elect a diversification distribution.


                                   ARTICLE XII

                                   TRUST FUND

     The Trust Fund shall be held by State Street Bank and Trust Company, as
Trustee, or by a successor trustee or trustees, for use in accordance with the

Similarly, the Trustee may be changed from time to time in the manner provided
in the Agreement and Declaration of Trust.

                                  ARTICLE XIII

            EXPENSES OF ADMINISTRATION OF THE PLAN AND THE TRUST FUND

     The Company shall bear all expenses of implementing this Plan and the
Trust. For its services, any corporate trustee shall be entitled to receive
reasonable compensation in accordance with its rate schedule in effect from time
to time for the handling of a retirement trust. Any individual Trustee shall be
entitled to such compensation as shall be arranged between the Company and the
Trustee by separate instrument; provided, however, that no person who is already
receiving full-time pay from any Employer or any Affiliate shall receive
compensation from the Trust Fund (except for the reimbursement of expenses
properly and actually incurred). The Company may pay all expenses of the
administration of the Trust Fund, including the Trustee's compensation, the
compensation of any investment manager, the expense incurred by the Plan
Administrator in discharging its duties, all income or other taxes of any kind
whatsoever that may be levied or assessed under existing or future laws upon or
in respect of the Trust Fund, and any interest that may be payable on money
borrowed by the Trustee for the purpose of the Trust and any Employer may pay
such expenses as relate to Participants employed by such Employer. Any such
payment by the Company or an Employer shall not be deemed a contribution to this
Plan. Such expenses shall be paid out of the assets of the Trust Fund unless
paid or provided for by the Company or another Employer. Notwithstanding
anything contained herein to the contrary, no excise tax or other liability
imposed upon the Trustee, the Plan Administrator or any other person for failure
to comply with the provisions of any federal law shall be subject to payment or
reimbursement from the assets of the Trust.


                                   ARTICLE XIV

                            AMENDMENT AND TERMINATION

     (a) RESTRICTIONS ON AMENDMENT AND TERMINATION. It is the present intention
of the Company to maintain the Plan set forth herein indefinitely. Nevertheless,
the Company specifically reserves to itself the right at any time, and from time
to time, to amend or terminate this Plan in whole or in part; provided, however,
that no such amendment:

          (1) shall have the effect of vesting in any Employer, directly or
     indirectly, any interest, ownership or control in any of the present or
     subsequent funds held subject to the terms of the Trust;

          (2) shall cause or permit any property held subject to the terms of
     the Trust to be diverted to purposes other than the exclusive benefit of
     the Participants and their beneficiaries or for the administrative expenses
     of the Plan Administrator and the Trust;

          (3) shall reduce any vested interest of a Participant on the later of
     the date the amendment is adopted or the date the amendment is effective,
     except as permitted by law; 

          (4) shall reduce the Accounts of any Participant;



                                      41.
<PAGE>   42

          (5) shall amend any vesting schedule with respect to any Participant
     who has at least three Years of Service at the end of the election period
     described below, except as permitted by law, unless each such Participant
     shall have the right to elect to have the vesting schedule in effect prior
     to such amendment apply with respect to him, such election, if any, to be
     made during the period beginning not later than the date the amendment is
     adopted and ending no earlier than sixty (60) days after the latest of the
     date the amendment is adopted, the amendment becomes effective or the
     Participant is issued written notice of the amendment by his Employer or
     the Plan Administrator; or

          (6) shall increase the duties or liabilities of the Trustee without
     its written consent.

     (b) AMENDMENT OF PLAN. Subject to the limitations stated in paragraph (a),
the Company shall have the power to amend this Plan in any manner that it deems
desirable, and, not in limitation but in amplification of the foregoing, it
shall have the right to change or modify the method of allocation of
contributions hereunder, to change any provision relating to the administration
of this Plan and to change any provision relating to the distribution or
payment, or both, of any of the assets of the Trust.

     (c) TERMINATION OF PLAN. Any Employer, in its sole and absolute discretion,
may permanently discontinue making contributions under this Plan or may
terminate this Plan and the Trust (with respect to all Employers if it is the
Company, or with respect to itself alone if it is an Employer other than the
Company), completely or partially, at any time without any liability whatsoever
for such permanent discontinuance or complete or partial termination. In any of
such events whether or not initiated by the Employer, the affected Participants,
notwithstanding any other provisions of this Plan, shall have fully vested
interests in the amounts credited to their respective Accounts at the time of
such complete or partial termination of this Plan and the Trust or permanent
discontinuance of contributions. All such vested interests shall be
nonforfeitable.

     (d) METHOD OF DISCONTINUANCE. In the event an Employer decides to
permanently discontinue making contributions, such decision shall be evidenced
by an appropriate resolution of its Board and a certified copy of such
resolution shall be delivered to the Plan Administrator and the Trustee. All of
the assets in the Trust Fund belonging to the affected Participants on the date
of discontinuance specified in such resolutions shall, aside from becoming fully
vested as provided in paragraph (c), be held, administered and distributed by
the Trustee in the manner provided under this Plan. In the event of a permanent
discontinuance of contributions without such formal documentation, full vesting
of the interests of the affected Participants in the amounts credited to their
respective Accounts will occur on the last day of the year in which a
substantial contribution is made to the Trust.

     (e) METHOD OF TERMINATION.



                                      42.
<PAGE>   43

          (1) In the event an Employer decides to terminate this Plan and the
     Trust, such decision shall be evidenced by an appropriate resolution of its
     Board and a certified copy of such resolution shall be delivered to the
     Plan Administrator and the Trustee. After payment of all expenses and
     proportional adjustments of individual accounts to reflect such expenses
     and other changes in the value of the Trust Fund as of the date of
     termination, each affected Participant or the beneficiary of any such
     Participant shall be entitled to receive, in a lump sum, any amount then
     credited to his Accounts.

          (2) At the election of the Participant, the Plan Administrator may
     transfer the amount of any Participant's distribution under this paragraph
     (e) to the trustee of another qualified plan or the trustee of an
     individual retirement account or individual retirement annuity instead of
     distributing such amount to the Participant. Any such election by a
     Participant shall be in writing and filed with the Plan Administrator.

     (f) INVOLUNTARY TERMINATION. Notwithstanding the provisions of paragraph
(a), if it is finally determined that the Plan and the Trust do not qualify
initially as a tax-free employees plan and trust under the Code, then, in that
event, at the election of the Company, the Plan and Trust may terminate as of
the date of such final determination, in which event the Plan Administrator
shall direct the Trustee to return Accounts transferred from the IDG ESOP to the
IDG ESOP (to the extent that the Trustee of the IDG ESOP agrees to such return),
and to pay the then aggregate of any remaining balances in the Employer
contribution accounts to the appropriate Employer.

               (1) The Participants and their beneficiaries shall have no
          further right under this Plan or the Trust; and

               (2) The Trustee shall be discharged of all obligations and duties
          under the Trust.


                                   ARTICLE XV

                                  MISCELLANEOUS

     (a) MERGER OR CONSOLIDATION. This Plan and the Trust may not be merged or
consolidated with, and the assets or liabilities of this Plan and the Trust may
not be transferred to, any other plan or trust unless each Participant would
receive a benefit immediately after the merger, consolidation or transfer, if
the plan and trust then terminated, that is equal to or greater than the benefit
the Participant would have received immediately before the merger, consolidation
or transfer if this Plan and the Trust had then terminated.

     (b)  (1) PROHIBITION ON ALIENATION. Except as provided in paragraphs (b)(2)
     and (b)(3), no Participant or beneficiary of a Participant shall have any
     right to assign, transfer, appropriate, encumber, commute, anticipate or
     otherwise alienate his interest in this Plan or 



                                      43.
<PAGE>   44

     the Trust or any payments to be made thereunder; no benefits, payments,
     rights or interests of a Participant or beneficiary of a Participant of any
     kind or nature shall be in any way subject to legal process to levy upon,
     garnish or attach the same for payment of any claim against the Participant
     or beneficiary of a Participant; and no Participant or beneficiary of a
     Participant shall have any right of any kind whatsoever with respect to the
     Trust, or any estate or interest therein, or with respect to any other
     property or right, other than the right to receive such distributions as
     are lawfully made out of the Trust, as and when the same respectively are
     due and payable under the terms of this Plan.

          (2) QUALIFIED DOMESTIC RELATIONS ORDERS. Notwithstanding the
     provisions of paragraph (b)(1), the Plan Administrator shall direct the
     Trustee to make payments pursuant to a Qualified Domestic Relations Order
     as defined in Section 414(p) of the Code and as determined by the
     Administrator pursuant to this subparagraph (2).

               (A) DETERMINATION. The Plan Administrator shall determine whether
          a court order purporting to qualify under Section 414(p) of the Code
          actually meets such requirements as soon as practicable following
          receipt of such order. The Administrator shall establish procedures
          for making such determination.

                    (i) The Administrator shall refuse to approve any order
               which, in its opinion, does not comply strictly with the
               requirements of Section 414(p) of the Code. No order may be
               approved if the Administrator determines that it contains any
               ambiguity, or if any provision is inconsistent with any other
               requirement of applicable law.

                    (ii) The Administrator may require an order to include
               provisions that it deems necessary to properly administer the
               order under the terms of this Plan, including (without
               limitation):

                         a. the amount or percentage of the Participant's
                    benefits to be paid to the alternate payee, such amount or
                    percentage to be determined as of a specified Plan Valuation
                    Date.

                         b. clear provisions specifying the disposition of
                    unpaid benefits of the alternate payee in the event of the
                    death of either the Participant or the alternate payee:

                               1. A qualified domestic relations order may
                          provide that the unpaid balance of an alternate
                          payee's benefits be paid to the alternate payee's
                          estate or personal representative. An alternate payee
                          may not designate an individual death beneficiary.



                                      44.
<PAGE>   45

                               2. If the alternate payee is to receive any
                          unpaid benefits provided under the order
                          notwithstanding the prior death of the Participant,
                          the order must clearly so provide in full compliance
                          with the provisions of ERISA and the Code.

                         c. clear provisions allocating any applicable annual
                    distribution limitation between (or among) the Participant
                    and any alternate payee(s).

               (B) NOTIFICATION. The Administrator shall notify the Participant
          and the alternate payee of receipt of such order as soon as
          practicable following such receipt. The Administrator shall notify the
          Participant and the alternate payee of the Plan Administrator's
          determination as to whether such order is qualified as soon as
          practicable following such determination. If the Plan Administrator is
          able to determine whether an order is qualified promptly upon receipt
          of such order, the Administrator may send one notice which informs the
          Participant and the alternate payee both of the receipt of the order
          and of the Administrator's determination.

               (C) SUSPENSE ACCOUNT WHILE ORDER IS BEING EVALUATED. During the
          time that the Plan Administrator is considering whether such an order
          is qualified, any amount to which the Administrator reasonably
          believes that the order purports to apply shall not be paid to the
          Participant, even if the Participant would otherwise be entitled to
          receive such amount.

                    (i) If an amount would otherwise be paid to the Participant
               while the Plan Administrator is considering such an order, such
               amount shall be credited to a separate suspense account. The
               Participant shall retain any right he may have to direct
               diversification of the investments of such suspense account to
               the same extent as if no order had been received.

                    (ii) If the Administrator determines that the order is
               qualified, the amounts in the suspense account shall be paid to
               the alternate payee to the extent provided in the order. Any
               remaining amounts in the suspense account shall be paid to the
               Participant. If the Administrator determines that the order is
               not qualified, the amounts in the suspense account shall be paid
               to the Participant.

                    (iii) The Plan Administrator shall determine the date
               following its determination as of which the amounts in the
               suspense account are to be released to the Participant and/or the
               alternate payee. The Administrator may allow a reasonable period
               during which either party may appeal its determination as to the
               status of the order before releasing the amounts from the
               suspense account. If either party appeals such determination, the



                                      45.
<PAGE>   46

               Administrator shall not release the amounts from the suspense
               account until the Administrator makes its decision on appeal. If
               a substitute order is received during the appeal period, the
               Administrator shall not release any amounts from the suspense
               account that the Administrator reasonably believes to be covered
               by the substitute order until after it has determined whether the
               substitute order is qualified.

                    (iv) No amount shall remain in a suspense account longer
               than 18 months, except that the receipt of a substitute order
               with respect to funds already held in a suspense account shall
               extend such period until 18 months following receipt by the
               Administrator of such substitute order. If, at the end of such
               period, the Administrator still has not determined whether the
               order (or substitute order) is qualified, the amounts in the
               suspense account shall be distributed to the Participant.

               (D) FREEZE ON ACCOUNT IN ANTICIPATION OF ORDER.

                    (i) If the Plan Administrator is informed that a person who
               would qualify as an alternate payee intends to obtain a qualified
               domestic relations order with respect to the Accounts of a
               Participant, the Administrator may refuse, for a reasonable
               period, to permit the distribution to the Participant from such
               Accounts of any amount which the Administrator reasonably
               believes such alternate payee will claim.

                    (ii) Even in the absence of specific information that a
               potential alternate payee is seeking a qualified domestic
               relations order, the Plan Administrator may refuse to permit the
               distribution to the Participant from his Accounts of any amount
               if the Administrator reasonably believes that distribution of
               such amount to the Participant would result in a violation of the
               community property rights of the Participant's spouse or former
               spouse.

                    (iii) In the event the Administrator refuses to permit a
               distribution in accordance with subsection (i) or (ii) of this
               section (D), the Participant shall retain any right he may have
               to direct diversification of the investments to the same extent
               as if the Administrator had not received such information or
               formed such belief.

               (E) TIME OF DISTRIBUTION TO ALTERNATE PAYEE. An alternate payee
          who is entitled to benefits under a qualified domestic relations order
          may begin to receive a distribution of benefits, to the extent
          permitted by such order, as soon as practicable following the Plan
          Administrator's determination that the order is qualified but not
          before the participant either terminates employment or reaches age 50,
          whichever is earlier.
