interests in the Merger that are in addition to their interests as stockholders
of the Company generally. The Company's Board of Directors (the "Board") was

<PAGE>   3
 
discussed these interests in connection with its consideration and approval of
the Merger Agreement. In considering the recommendation of the Board with
respect to the Offer and the Merger, the stockholders of the Company should be
aware of these interests which may present actual or potential conflicts of
interest.
 
     Pursuant to the Merger Agreement, the Company has agreed to use all
reasonable efforts to provide that, upon consummation of the Merger, each then
outstanding option or warrant to purchase Shares, whether or not then
exercisable or vested, will be acquired by the Company for cancellation in
consideration for payment to the holders of such options and warrants of an
amount in respect thereof equal to the excess of the Per Share Amount over the
exercise price thereof multiplied by the number of Shares subject thereto. The
amounts to be received by Mr. Meckler, Christopher S. Cardell, Carl S. Pugh and
Christopher J. Baudouin, the executive officers of the Company, in respect of
such options are $5,071,650, $861,470, $442,500 and $85,310, respectively.
 
     Pursuant to the Merger Agreement, Parent has agreed to cause the Surviving

effective time of the Merger (the "Effective Time") to the fullest extent

equivalent to the current policies of the Company, subject to certain
limitations, for six years after the Effective Time.
 
     Pursuant to the Merger Agreement, Parent has agreed to (A) contribute all
assets (the "iWorld Assets") of iWorld Corporation, a Delaware corporation and
wholly owned subsidiary of the Company, to a newly formed Delaware limited
liability company ("iWorld") and (B) the acquisition by Mr. Meckler and/or one
or more persons under his control of 80.1% of the equity interests in iWorld for
an aggregate purchase price of $18.0 million (the "iWorld Transaction"). At the
Effective Time, Parent, the Purchaser and iWorld have agreed to enter into
certain agreements with respect to the operation of iWorld. See "The Merger
Agreement -- The iWorld Agreements" in Section 10 of the Offer to Purchase and

consulting services to Parent and the Surviving Corporation and will abide by a
covenant not to compete with the business of Parent, the Surviving Corporation
or any entities controlled by either in exchange for an annual fee of $100,000
payable monthly during such period. See "Consulting Agreement" in Section 10 of
the Offer to Purchase, which section is incorporated herein by reference.

certain non-public information furnished by the other. The foregoing description
is qualified by reference to the text of the Confidentiality Agreement, a copy
of which is filed as Exhibit 11 hereto.
 
ITEM 4. THE SOLICITATION OR RECOMMENDATION.
 
     (a) RECOMMENDATION OF THE BOARD OF DIRECTORS
 
     AT A MEETING HELD ON OCTOBER 7, 1998, THE BOARD UNANIMOUSLY APPROVED THE
OFFER AND ADOPTED THE MERGER AGREEMENT AND DETERMINED THAT THE TERMS OF THE
OFFER, THE MERGER AND THE IWORLD TRANSACTION ARE FAIR TO, AND IN THE BEST
INTERESTS OF, THE COMPANY AND ITS STOCKHOLDERS, AND UNANIMOUSLY RECOMMENDED THAT
THE COMPANY'S STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO
THE OFFER.
 
     A letter to the Company's stockholders communicating the Board's
recommendation and the press releases announcing the Merger Agreement and
related transactions are filed herewith as Exhibits 8, 9 and 10, respectively,
and are incorporated herein by reference.
 
     (b)(i) BACKGROUND OF THE OFFER; CONTACTS WITH PARENT
 
     During the spring of 1997 and the spring and summer of 1998, Allen &
Company Incorporated ("Allen & Company") had discussions on behalf of the
Company with the management of several companies which had
                                        2
<PAGE>   4
 
approached the Company, and two companies which Allen & Company had approached
with the approval of the Company, regarding the possibility of various strategic
transactions involving the Company. Confidentiality agreements were entered into
with two companies in 1997; however, none of the discussions with such companies
advanced beyond a preliminary stage. In the spring and summer of 1998, Allen &
Company had preliminary discussions, pursuant to confidentiality agreements,
with several companies regarding a potential strategic combination with the
Company and discussions with one company regarding a potential strategic
transaction involving some, but not all, of the assets of the Company. The
Company reached an oral understanding regarding an approximate three week period
of exclusivity with one of the companies interested in a potential strategic
combination; however, the period of exclusivity expired prior to a letter of
intent being executed with such company.
 
     Thereafter, on September 16, 1998, at the instructions of Thomas L. Kemp,
Chief Executive Officer of Parent, representatives of Donaldson, Lufkin &
Jenrette Securities Corporation ("DLJ") called Alan M. Meckler, Chief Executive
Officer of the Company, to discuss a possible acquisition of the Company by
Parent. Prior to making this call, there had been no contacts between Parent or
its representatives and the Company with respect to any possible combination
between them. Mr. Meckler informed DLJ that he had been contacted by other
parties interested in a strategic transaction with the Company and requested
that they contact Allen & Company. Between September 17, 1998 and September 21,
1998, representatives of DLJ and Allen & Company spoke periodically and
discussed issues related to Parent's ability to complete an acquisition of the
Company. Legal counsel to the Company delivered a draft confidentiality
agreement to DLJ on September 21, 1998. On September 21, 1998, Mr. Meckler and
Mr. Kemp had a conversation in which Mr. Meckler informed Mr. Kemp that the
Company was considering potential strategic transactions, including a possible
sale of the Company, and agreed to meet with Mr. Kemp and representatives of
Purchaser and the Company at DLJ's offices in New York, New York on September
24, 1998.
 
     On September 23, 1998, Parent and the Company entered into the
Confidentiality Agreement. At their meeting on September 24, 1998, Mr. Kemp
presented a draft letter of intent to Mr. Meckler that provided, among other
things, for Parent to acquire the Company at a price of $29.00 per Share.
 
     Between the afternoon of September 24, 1998 and the evening of September
25, 1998, representatives of the Company and representatives of Parent
negotiated the terms of a letter agreement between the Company and Parent. In
the evening on September 25, 1998, Parent, the Company and Mr. Meckler executed
a letter of intent that (a) outlined the general terms of (i) a potential
acquisition of the Company by Parent at a price of $29.00 per Share and (ii)
concurrently with such acquisition, the sale to Mr. Meckler for $15.0 million of
a 50% economic interest in the Internet web site business currently operated by
the Company, the proceeds of which would partially fund Parent's acquisition of
the Company, and (b) provided for exclusive negotiations between the Company and
Parent through October 7, 1998, with respect to executing definitive
documentation regarding these transactions. The letter of intent expressly
provided that the transactions outlined in such letter were subject to a
satisfactory due diligence review by Parent, the approval of such transactions
by the boards of directors of Parent and the Company and the execution of
definitive documentation.
 
     Following a due diligence review by Parent of the Company, negotiations of
the Merger Agreement and the related agreements commenced on September 27, 1998,
when the Company furnished Parent with a draft of a merger agreement. During the
course of negotiations, Parent and Mr. Meckler agreed that Parent would increase
the percentage ownership it would sell to Mr. Meckler in the Internet web site
business to 80.1% in exchange for an increase in the sales price to $18 million.
The price per Share offered remained at $29.00.
 
     On October 1, 1998, the Company, Parent and their respective
representatives met again, at the offices of Jones, Day, Reavis & Pogue in New
York, New York, to discuss and resolve certain issues relating to the proposed
transaction. The Board met on October 3, 1998 to discuss various aspects of the
proposed transaction. That meeting was adjourned and was reconvened on October
6, 1998, at which time (i) Allen & Company presented to the Board its opinion
that the consideration to be received pursuant to the Merger Agreement by the
holders of the Company's common stock, options and warrants to purchase common
stock is fair to such holders from a financial point of view and that the
Proposed Transactions (as defined in Allen & Company's fairness opinion included
as Schedule I hereto) are fair to the Company from a financial point of view and
(ii) the
 
                                        3
<PAGE>   5
 
Company's outside legal counsel summarized for the Board the terms of the Offer,
the Merger, the Merger Agreement, the iWorld Transaction and the documentation
related thereto, including provisions relating to the fee which would become
payable by the Company to Parent in the event that the Company were to accept a
Superior Proposal (as defined in the Merger Agreement). The meeting was again
adjourned pending the negotiation of final documentation, and was reconvened on
October 7, 1998 following the completion of such negotiation. During the
Company's October 7, 1998 Board meeting, Mr. Meckler offered to leave the
meeting during the Board's discussion and consideration of the Merger and the
iWorld Transaction, but the Board declined Mr. Meckler's offer and engaged in
such discussions with Mr. Meckler present. During such Board meeting, the Board
unanimously approved the Offer, the Merger, the Merger Agreement, the iWorld
Transaction and the transactions contemplated thereby for the reasons described
below. The board of directors of Parent had unanimously approved (with two
directors absent) the Merger Agreement, contingent upon the negotiation of final
documentation, at a meeting held on October 6, 1998. The parties executed the
Merger Agreement in the evening on October 7, 1998, and publicly announced the
transaction on the morning of October 8, 1998.
 
     (b)(ii) REASONS FOR THE RECOMMENDATION BY THE BOARD OF DIRECTORS
 
     In reaching its conclusions and recommendation described above, the Board
considered a number of factors, including, without limitation, the following:
 
     (a) The financial and other terms and conditions of (i) the Offer, (ii) the
Merger, (iii) the Merger Agreement and (iv) the iWorld Transaction.
 
     (b) The historical market price of, and recent trading activity in, the
Shares, particularly the fact that the Offer and the Merger will enable the
stockholders of the Company to realize a premium of approximately 44% over the
closing price of the Shares on the last trading day prior to the public
announcement on October 8, 1998 of the Merger Agreement.
 
     (c) Conversations conducted by Allen & Company on behalf of the Company
with other parties interested in a potential strategic transaction with the
Company.
 
     (d) The presentation of Allen & Company. In evaluating the financial and
other terms of the Offer, the Company's Board of Directors took into account the
presentation of Allen & Company at the meeting of the Board on October 6, 1998,
at which meeting Allen & Company delivered its oral opinion, subsequently
confirmed in writing, to the effect that, as of such date, (a) the consideration
to be received pursuant to the Merger by the holders of the Common Stock and
options and warrants to purchase Common Stock is fair to such holders from a
financial point of view, and (b) the terms of the Merger and the iWorld
Transaction (collectively, the "Proposed Transactions") are fair to the Company
from a financial point of view. In arriving at its opinion, Allen & Company
informed the Board that it (i) reviewed the terms and conditions of the Proposed
Transactions, including the draft Merger Agreement and the draft agreements
ancillary thereto, including the draft agreements relating to the iWorld
Transaction (none of which prior to the delivery of Allen & Company's opinion
had been executed by the parties), as well as draft commitment letters
summarizing certain of Parent's proposed financing arrangements; (ii) analyzed
publicly available historical business and financial information relating to the
Company and Parent, as presented in documents filed with the Securities and
Exchange Commission; (iii) reviewed certain financial, operating and budgetary
data provided to Allen & Company by the Company relating to its businesses; (iv)
conducted discussions with certain members of the senior management of the
Company with respect to the financial condition, business, operations, strategic
objectives and prospects of the Company, as well as industry trends prevailing
in the Company's business; (v) reviewed and analyzed public information,
including certain stock market data and financial information relating to
selected public companies in lines of business which Allen & Company believed to
be comparable to the Company's, as well as analysts' reports and estimates for
the Company; (vi) reviewed the trading history of the Company's Common Stock and
Parent's common stock, including their performance in comparison to market
indices and to selected companies in comparable businesses; (vii) reviewed
public financial and transaction information relating to business combinations
which Allen & Company deemed to be comparable to the Proposed Transactions;
(viii) considered premiums and multiples paid in recent transactions which Allen
& Company deemed comparable to the Merger; and (ix) conducted such other
financial analyses and investigations as Allen & Company deemed necessary or
appropriate for the purposes of the opinion expressed therein.
                                        4
<PAGE>   6
 
     The full text of the written opinion of Allen & Company, dated October 7,
1998, which is set forth as Schedule I hereto and is incorporated herein by
reference, describes the assumptions made, matters considered and limits on the
review undertaken. The Company's stockholders are urged to read the opinion
carefully and in its entirety. Allen & Company's opinion does not constitute a
recommendation that the Company pursue the Proposed Transactions or that any
stockholder of the Company accept the Offer or vote to approve the Proposed
Transactions. In considering such opinion, the Company's Board was aware that
Allen & Company is entitled to certain fees described elsewhere herein in
connection with Allen & Company's engagement by the Company.
 
     (e) The fact that the structure of the acquisition of the Company by Parent
as provided for in the Merger Agreement involves a cash tender offer for all
outstanding Shares to be commenced within five business days of the public
announcement of the Merger Agreement to be followed as promptly as practicable
by a merger for the same consideration, thereby enabling the Company's
stockholders to obtain cash for their Shares at the earliest possible time.
 
     (f) The fact that the Merger Agreement, which prohibits the Company, its
subsidiaries and their respective officers, directors, employees,
representatives or agents from soliciting, initiating or encouraging any
competing Acquisition Transaction (as defined in the Merger Agreement) or
participating in any discussion regarding any Acquisition Transaction, does
permit the Company to furnish non-public information to, and participate in
negotiations with, any person that makes an unsolicited Superior Proposal (as
defined in the Merger Agreement) if the Board, based upon the advice of the
Company's financial advisor and outside counsel, determines in good faith and
reasonable judgment that failing to take such action would create a reasonable
possibility of a breach of the fiduciary duties of the Board under applicable
law.
 
     (g) The fact that in the event that the Board decides to accept an
Acquisition Transaction with a third party, the Board may terminate the Merger
Agreement following the expiration of the Offer and pay Parent a termination fee
of $10,000,000 plus up to $6,000,000 in fees and expenses. The Board did not
believe that such termination provision would be a significant deterrent to a
higher offer by a third party interested in acquiring the Company.
 
     (h) The fact that Mr. Meckler, the beneficial owner of approximately 26% of
the outstanding Shares, was willing to enter into the Tender, Voting and Option
Agreement pursuant to which Mr. Meckler agreed to tender all of his Shares
pursuant to the Offer and, in the event a stockholder vote is required, to vote
his Shares in favor of the Merger.
 
     (i) The familiarity of the Board with the business, results of operations,
properties and financial condition of the Company, the competitive nature of the
industry in which it operates and the prospects of the Company, including its
prospects if it were to remain independent.
 
     (j) The regulatory approvals required to consummate the Merger, including,
among others, antitrust approvals, and the prospects for receiving such
approvals.
 
     The foregoing discussion of the information and factors considered and
given weight by the Board is not intended to be exhaustive. The Board did not
quantify or otherwise assign relative weights to the specific factors considered
in reaching its determination.
 
ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED.
 
     The Company has retained Allen & Company to render financial advisory
services to the Company with respect to the Offer and the Company's strategic
alternatives. Pursuant to an engagement letter, dated April 10, 1998, the
Company agreed to pay Allen & Company a cash fee equal to 1% of the
consideration received in connection with consummation of the Offer. The Company
also agreed to pay Allen & Company a cash fee in the amount of $750,000 in the
event Allen & Company has provided a fairness opinion to the Board in connection
with a transaction which is ultimately not consummated. The Company also has
agreed to reimburse Allen & Company's reasonable out-of-pocket expenses
including the fees and expenses of Allen & Company's counsel, and indemnify and
defend Allen & Company and certain related persons against certain liabilities
in connection with the engagement.
 
                                        5
<PAGE>   7
 
     Except as disclosed herein, neither the Company nor any person acting on
its behalf currently intends to employ, retain or compensate any other person to
make solicitations or recommendations to security holders on its behalf
concerning the Offer or the Merger.
 
ITEM 6. RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES.
 
     (a) Except for the issuance of Shares upon exercise of outstanding options,
no transactions in Shares have been effected during the past 60 days by the
Company or, to the best of the Company's knowledge, by an executive officer,
director, subsidiary or affiliate of the Company.
 
     (b) To the best of the Company's knowledge, each executive officer,
director and affiliate of the Company currently intends to tender all Shares to
Purchaser over which he or she has sole dispositive power as of the expiration
date of the Offer.
 
ITEM 7. CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY.
 
     (a) Except as set forth above or in this Schedule 14D-9, no negotiation is
being undertaken or is underway by the Company in response to the Offer which
relates to or would result in: (1) an extraordinary transaction such as a merger
or reorganization involving the Company or any subsidiary of the Company; (2) a
purchase, sale or transfer of a material amount of assets by the Company or any
subsidiary of the Company; (3) a tender offer for or other acquisition of
securities by or of the Company; or (4) any material change in the present
capitalization or dividend policy of the Company.
 
     (b) Except as described in Item 3(b) or 4 above (the provisions of which
are hereby incorporated by reference), there are no transactions, Board
resolutions, agreements in principle or signed contracts in response to the
Offer that relate to or would result in one or more of the events referred to in
Item 7(a) above.
 
ITEM 8. ADDITIONAL INFORMATION TO BE FURNISHED.
 
     (a) Information Statement
 
     The Information Statement attached as Schedule II hereto is being furnished
in connection with the possible designation by Purchaser, pursuant to the Merger
Agreement, of certain persons to be appointed to the Board other than at a
meeting of the Company's stockholders as described in Item 3 above.
 
     (b) Section 203 of the Delaware General Corporation Law
 
     As a Delaware corporation, the Company is subject to Section 203 ("Section
203") of the Delaware General Corporation Law. Under Section 203, certain
"business combinations" between a Delaware corporation whose stock is publicly
traded or held of record by more than 2,000 stockholders and an "interested
stockholder" are prohibited for a three-year period following the date that such
a stockholder became an interested stockholder, unless (i) the corporation has
elected in its original certificate of incorporation not to be governed by
Section 203 (the Company did not make such an election), (ii) the transaction in
which the stockholder became an interested stockholder or the business
combination was approved by the Board of Directors of the corporation before the
other party to the business combination became an interested stockholder, (iii)
upon consummation of the transaction that made it an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation
outstanding at the commencement of the transaction (excluding voting stock owned
by directors who are also officers or held in employee benefit plans in which
the employees do not have a confidential right to tender or vote stock held by
the plan) or (iv) the business combination was approved by the Board of
Directors of the corporation and ratified by 66 2/3% of the voting stock which
the interested stockholder did not own. The term "business combination" is
defined generally to include mergers or consolidations between a Delaware
corporation and an "interested stockholder," transactions with an "interested
stockholder" involving the assets or stock of the corporation or its
majority-owned subsidiaries and transactions which increase an "interested
stockholder's" percentage ownership of stock. The term "interested stockholder"
is defined generally as a stockholder who, together with affiliates and
associates, owns (or, within three years prior, did own) 15% or more of a
Delaware corporation's voting stock.

     In accordance with the Merger Agreement and Section 203, the Board approved
the Offer, the Merger, the iWorld Transaction, the Tender, Voting and Option
Agreement and the other transactions contemplated by the Merger Agreement and,
therefore, the restrictions of Section 203 are inapplicable to the Offer, the
Merger and the related transactions.
 
     (c) Antitrust
 
     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act") and the rules that have been promulgated thereunder by the
Federal Trade Commission ("FTC"), certain acquisition transactions may not be
consummated unless certain information has been furnished to the Antitrust
Division of the Department of Justice (the "Antitrust Division") and the FTC and
certain waiting period requirements have been satisfied. The acquisition of
Shares pursuant to the Offer is subject to such requirements. There may be
similar antitrust requirements in other jurisdictions.
 
     On October 15, 1998, Parent filed with the FTC and the Antitrust Division a
Premerger Notification and Report Form in connection with the purchase of Shares
pursuant to the Offer. Under the provisions of the HSR Act applicable to the
Offer, the purchase of Shares pursuant to the Offer may not be consummated until
the expiration of a 15-calendar day waiting period following the filing by
Parent, unless both the Antitrust Division and the FTC terminate the waiting
period prior thereto. If, within such 15-calendar day waiting period, either the
Antitrust Division or the FTC requests additional information or documentary
material from Parent, the waiting period would be extended for an additional 10
calendar days following substantial compliance by Parent with such request.
Thereafter, the waiting period could be extended only by court order. Only one
extension of such waiting period pursuant to a request for additional
information is authorized by the HSR Act and the rules promulgated thereunder,
except by court order. Any such extension of the waiting period will not give
rise to any withdrawal rights not otherwise provided for by applicable law.
 
     The October 15, 1998 Premerger Notification and Report Form filing
described above was also applicable to the Option granted to Purchaser pursuant
to the Tender, Voting and Option Agreement. Under the provisions of the HSR Act
applicable to the Option, the purchase of Shares pursuant to the Option may not
be consummated until the expiration of a 30-calendar day waiting period
following the filing by Parent, unless both the Antitrust Division and the FTC
terminate the waiting period thereto. If, within such 30-calendar day waiting
period, either the Antitrust Division or the FTC requests additional information
or documentary material from Parent, the waiting period would be extended for an
additional 20 calendar days following substantial compliance by Parent with such
request. Thereafter, the waiting period could be extended only by court order.
Only one extension of such waiting period pursuant to a request for additional
information is authorized by the HSR Act and the rules promulgated thereunder,
except by court order. Pursuant to the Tender, Voting and Option Agreement, if
the Option becomes exercisable, it would continue to be exercisable until 10
days after the waiting period (including as extended) under the HSR Act has
expired.
 
     The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed acquisition of Shares by
Purchaser pursuant to the Offer. At any time before or after the purchase by
Purchaser of Shares pursuant to the Offer, either of the FTC or the Antitrust
Division could take such action under the antitrust laws as it deems necessary
or desirable in the public interest, including seeking to enjoin the purchase of
Shares pursuant to the Offer or seeking the divestiture of Shares purchased by
Purchaser or the divestiture of substantial assets of Parent, its subsidiaries
or the Company. Private parties and state attorneys general may also bring legal
action under federal or state antitrust laws under certain circumstances.
 
     Based upon an examination of publicly available information, and
information provided to the Company by Parent, relating to the businesses in
which Parent and its subsidiaries are engaged, the Company has determined that
the Company and Parent both provide similar services in certain geographic
areas. Although the Company believes that the Purchaser's acquisition of Shares
pursuant to the Offer would not violate the antitrust laws, there can be no
assurance that a challenge to the Offer on antitrust grounds will not be made
or, if such challenge is made, what the outcome will be. See Item 3(b) for
certain conditions to the Offer, including conditions with respect to litigation
and certain government actions.

                                October 7, 1998
 
Members of the Board of Directors
Mecklermedia Corp.
20 Ketchum Street
Westport, Connecticut 06880
 
To the Board of Directors
 
     We are pleased to confirm in writing our presentation to a meeting of the
Board of Directors on Wednesday, October 6, 1998, of our opinion, as of this
date, as to (a) the fairness, from a financial point of view, of the
consideration to be received by the holders of the outstanding shares of Common
Stock, .01 par value per share (the "Common Stock"), and options and warrants to
purchase Company Common Stock of Mecklermedia Corp., a Delaware corporation (the
"Company"), and (b) the fairness, from a financial point of view, to the Company
of the terms of the Proposed Transactions referred to hereinafter.
 
     Pursuant to the proposed Agreement and Plan of Merger (the "Merger
Agreement"), to be entered into by and among the Company, Penton Media Inc., a
Delaware corporation, (the "Purchaser"), and a wholly-owned subsidiary of the
Purchaser (the "Merger Sub"), the Company will enter into a business combination
transaction effected by a cash tender offer made by Purchaser and Merger Sub for
Company Common Stock and options and warrants to purchase Company Common Stock,
to be followed by a merger of Merger Sub with and into the Company (the "Merger
Transaction"). In connection with the Merger Transaction, Purchaser at the
Effective Time will cause the organization of a limited liability company under
Delaware law ("Newco"), to which Purchaser is to contribute the Company's
internet business assets in consideration for Newco's issuance to Purchaser of
19.9% of Newco's equity interest. At the Effective Time, in consideration of the
payment of $18 million, Newco is to issue 80.1% of its equity interest to Alan
M. Meckler, the Company's founder, principal stockholder and Chief Executive
Officer, which equity interest is subject to dilution pursuant to an option
granted by Mr. Meckler to Purchaser (the "Newco Transaction" and, collectively
with the Merger Transaction, the "Proposed Transactions"). In connection with
the Proposed Transactions, Mr. Meckler has granted Purchaser the option to
purchase for cash and without interest his Common Stock at the same price per
share offered to other Company stockholders in the Merger Transaction. Unless
otherwise specifically defined herein, all capitalized terms used herein shall
have the meanings ascribed to such terms in the Merger Agreement.
 
     Pursuant to the terms, and subject to the conditions contained in, the
documentation relating to the Proposed Transactions, among other things, (i)
Purchaser will make a tender offer to purchase all shares of Company Common
Stock for a purchase price of $29 in cash, without interest, subject to certain
terms and conditions; (ii) Purchaser will offer to purchase Company issued
warrants and options to purchase Common Stock in cash without interest for a
price equal to the difference between $29 and the exercise price of such
warrants and options; and (iii) Mr. Meckler will acquire an 80.1% equity
interest in the Company's internet business assets held by Newco for an
aggregate purchase price of $18 million in cash (subject to dilution by
Purchaser's option to purchase from Mr. Meckler 10% of Newco), and the remaining
19.9% equity interest in Newco will be issued to Purchaser or one of its
affiliates. As part of the Proposed Transactions, Newco and Purchaser are to
enter into license and service agreements, and Mr. Meckler will enter into a
non-competition and consulting agreement with Purchaser.
 
     We understand that all approvals required for the consummation of the
Proposed Transactions have been or, prior to consummation of the Proposed
Transactions, will be obtained. We understand Purchaser has obtained financing
commitments subject to certain terms and conditions which commitments, when
funded and combined with the existing working capital of the Purchaser and the
Company, will be sufficient to timely meet Purchaser's obligations under the
Merger Agreement. We note the Proposed Transactions are conditioned on the
funding of such financing commitments.

     As you know Allen & Company Incorporated ("Allen") will receive a fee for
preparing and rendering this opinion pursuant to the engagement letter agreement
by and between the Company and Allen. We note that Allen beneficially owns
30,000 shares of the Company's Common Stock.
 
     In arriving at our opinion, we have among other things:
 
          (i) reviewed the terms and conditions of the Proposed Transactions,
     including the draft Merger Agreement and the draft agreements ancillary
     thereto, including the draft Newco Agreement between Newco and the
     Purchaser (none of which prior to the delivery of our opinion has been
     executed by the parties), as well as commitment letters summarizing certain
     of Purchaser's financing arrangements;
 
          (ii) analyzed publicly available historical business and financial
     information relating to the Company and the Purchaser, as presented in
     documents filed with the Securities and Exchange Commission;
 
          (iii) reviewed certain financial, operating and budgetary data
     provided to us by the Company relating to its businesses;
 
          (iv) conducted discussions with certain members of the senior
     management of the Company with respect to the financial condition,
     business, operations, strategic objectives and prospects of the Company, as
     well as industry trends prevailing in the Company's business;
 
          (v) reviewed and analyzed public information, including certain stock
     market data and financial information relating to selected public companies
     in lines of business which we believe to be comparable to the Company's, as
     well as analysts' reports and estimates for the Company;
 
          (vi) reviewed the trading history of the Company's and the Purchaser's
     Common Stock, including their performance in comparison to market indices
     and to selected companies in comparable businesses;
 
          (vii) reviewed public financial and transaction information relating
     to business combinations we deemed to be comparable to the Proposed
     Transactions;
 
          (viii) considered premiums and multiples paid in recent transactions
     we deemed comparable to the Merger Transaction;
 
          (ix) conducted such other financial analyses and investigations as we
     deemed necessary or appropriate for the purposes of the opinion expressed
     herein.
 
     In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of the financial and other information respecting the Company and
the Purchaser and any other information provided to us, and we have not assumed
any responsibility for any independent verification of such information or any
independent valuation or appraisal of any of the assets of the Company. With
respect to the business plans referred to above, we have assumed that they have
been reasonably prepared on a basis reflecting the best currently available
information and the good faith estimates and judgments of the management of the
Company as to the future financial performance of the Company's business.
 
     In addition to our review and analysis of the specific information set
forth above, our opinion herein reflects and gives effect to our knowledge of
the industry and our assessment of general economic, monetary and market
conditions existing as of the date hereof as they may affect the business and
prospects of the Company.
 
     We have prepared this opinion at the request and for the benefit of the
Board of Directors of the Company, and consent to its inclusion in filings the
Company may be required to make with the Securities and Exchange Commission. The
opinion rendered herein does not constitute a recommendation that the Company
pursue the Proposed Transactions or that any stockholder of the Company vote to
approve the Proposed Transactions.

     Based on and subject to the foregoing, we are of the opinion that, as of
this date, (a) the consideration to be received pursuant to the Merger
Transaction by the holders of the Company's Common Stock and options and
warrants to purchase Common Stock is fair to such holders from a financial point
of view, and (b) the terms of the Proposed Transactions are fair to the Company
from a financial point of view.
 
                                             Very truly yours,

                     INFORMATION PURSUANT TO SECTION 14(f)
                     OF THE SECURITIES EXCHANGE ACT OF 1934
                           AND RULE 14f-1 THEREUNDER
 
     The following information is being furnished to holders of the common
stock, par value $0.01 per share ("Common Stock" or the "Shares"), of
Mecklermedia Corporation, a Delaware corporation (the "Company"), in connection
with the possible designation by Penton Media, Inc., a Delaware corporation
("Parent"), of at least a majority of the board of directors of the Company
pursuant to the terms of an Agreement and Plan of Merger, dated as of October 7,
1998 (the "Merger Agreement"), by and among the Company, Parent, Internet World
Media, Inc., a Delaware corporation and wholly owned subsidiary of Parent
("Purchaser") and Alan M. Meckler. THIS INFORMATION IS BEING PROVIDED SOLELY FOR
INFORMATIONAL PURPOSES AND NOT IN CONNECTION WITH A VOTE OF THE COMPANY'S
STOCKHOLDERS.
 
     The Merger Agreement provides that promptly following the purchase by
Purchaser of any Shares pursuant to the Offer, Parent may request that the
Company take all actions necessary to cause persons designated by Parent to
become directors of the Company (the "Parent Designees") so that the total
number of directorships held by such persons is proportionate to the percentage
calculated by dividing (i) the number of Shares accepted for payment pursuant to
the Offer plus Shares beneficially owned by Purchaser by (ii) the total number
of Shares outstanding at the time of acceptance of the Shares for payment
pursuant to the Offer; provided that prior to the consummation of the Merger,
the board of directors of the Company (the "Board") shall always have at least
one member who is neither an officer, designee, shareholder or affiliate of
Parent. The Company has also agreed to increase the size of the Board or
exercise its best efforts to secure the resignation of existing directors to
ensure that it has complied with this provision of the Merger Agreement.
 
     The information contained in this Schedule II concerning Purchaser has been
furnished to the Company by Purchaser, and the Company assumes no responsibility
for the accuracy or completeness of any such information.
 
                        VOTING SECURITIES OF THE COMPANY
 
     As of October 14, 1998, there were issued and outstanding 9,109,742 shares

BOARD COMMITTEES AND MEETINGS
 
     The Board held four meetings during fiscal 1998. Each Director (other than
Charles R. Ellis, who joined the Board in April 1998) attended at least 75% of
the aggregate of (i) the total number of meetings of the Board and (ii) the
total number of meetings held by all Committees of the Board on which such
Director served.
 
     The Audit Committee is composed of three directors who are not officers or
employees of the Company. The Audit Committee held one meeting during fiscal
1998. The Audit Committee recommends to the Board the appointment of the
independent auditors, subject to approval by the stockholders of the Company;
reviews the independent auditor's report and management letters and reports to
the Board with respect thereto; reviews with management the Company's accounting
policies and procedures, including its internal accounting controls; determines
whether there are any conflicts of interest in financial or business matters
between the Company and any of its officers or employees; and reviews the
recommendations of the independent auditors. The Audit Committee also performs
such other tasks as are assigned to it from time to time by the Board.
 
     The Compensation Committee reviews and approves or recommends to the Board
the compensation and terms of employment of the Chief Executive Officer and the
President and Chief Operating Officer of the Company. The Compensation Committee
held one meeting during fiscal 1998.
 
     The Company does not have a nominating committee.
 
     After the consummation of the Merger, it is expected that the Company's
Board will act to appoint new members to the Audit and Compensation committees.
To the Company's knowledge, no decision has been made by the Purchaser Designees
regarding the membership of any such committees of the Board.
 
COMPENSATION OF DIRECTORS
 
     Directors of the Company who are also employees of the Company do not
receive any compensation specifically relating to their duties as directors.
 
     The Company's 1995 Stock Option Plan provides a non-discretionary formula
(the "Non-discretionary Formula") for Non-Employee Directors (as such term is
defined in Rule 16b-3 promulgated under the Exchange Act) which automatically
provides for a one-time grant to each Non-Employee Director of non-qualified
options to acquire 10,000 shares of Common Stock. With respect to Wayne A.
Martino, such grant occurred on March 16, 1995, after the stockholders approved
the 1995 Stock Option Plan. These options vested on the date of the grant. With
respect to Messrs. Davies and Lippincott, such grant, which vests equally over a
three-year period, occurred on January 25, 1996, the date on which both became
members of the Board of Directors. With respect to Mr. Bach, such grant, which
vests equally over a three-year period, occurred on February 14, 1997, the date
on which Mr. Bach became a Director. With respect to Ms. Chell, such grant,
which vests equally over a three-year period, occurred on December 15, 1997, the
date on which Ms. Chell became a Director. With respect to Mr. Ellis, such
grant, which vests equally over a three-year period, occurred on April 8, 1998,
the date on which Mr. Ellis became a Director. In addition, the
Non-discretionary Formula provides for an automatic grant, on the date of the
annual meeting of stockholders of the Company for each fiscal year, to each
Non-Employee Director, of options to acquire 1,000 shares of Common Stock
provided that such director has been a director for more than six months. The
grant of options to purchase 1,000 shares of Common Stock vests equally over a
three-year period. The purchase price of the option shares purchasable pursuant
to an option granted under the Non-discretionary Formula is 100% of the "fair
market value" of the Common Stock on the date the option is granted under the
1995 Stock Option Plan.
 
     During the fiscal year ended September 30, 1998, Gilbert F. Bach, Wayne A.
Martino, Michael J. Davies and Walter H. Lippincott were each granted options to
acquire 1,000 shares of Common Stock. Options to acquire 10,000 shares of Common
Stock were issued to Charles R. Ellis and Beverly C. Chell, as described above.
In addition, Non-Employee Directors receive an annual retainer of $4,000 and
$1,000 for each Board of Directors meeting attended. Wayne A. Martino, Michael
J. Davies, Walter H. Lippincott, Gilbert F. Bach and Beverly C. Chell each
earned $8,000 from the annual retainer for serving on the Board and for
attending Board of Directors meetings in fiscal 1998. Charles R. Ellis earned
$2,000 in fiscal 1998.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     The Compensation Committee of the Board of Directors ("Compensation
Committee") determines and reviews the compensation of the Company's Chief
Executive Officer and the President and Chief Operating Officer. It also reviews
and approves any employment, severance or similar agreements for those
individuals. The Compensation Committee is charged with fixing, on an annual
basis, the compensation of the Chief Executive Officer and the President and
Chief Operating Officer, subject to the approval of the Board, and reviewing and
recommending to the Board any employment, severance or similar agreements for
these individuals. The entire Board determines the amount, if any, of the
Company's contributions pursuant to its 401(k) Plan. While other compensation
decisions generally are not submitted to the Board, the Board has the ultimate
power and authority with respect to compensation matters.
 
     The members of the Compensation Committee reviewed salaries paid to the
Named Executive Officers in fiscal 1998 and approved salary increases for fiscal
1999 and intends to approve bonuses payable in fiscal 1999 with respect to
fiscal 1998 to the Named Executive Officers of the Company.
 
     The Compensation Committee seeks to compensate executive officers at levels
competitive with other companies comparable in size in the same industry and to
provide short-term rewards and long-term incentives for superior individual and
corporate performance. In making compensation decisions, the Compensation
Committee periodically reviews information about the compensation paid or
payable to officers of comparably sized public companies and the compensation
recommendations of Mr. Meckler, the Chairman of the Board and Chief Executive
Officer of the Company. The Compensation Committee does not have target amounts
of stock ownership for the Company's executive officers.
 
     The key components of executive officer compensation are base salary,
bonuses and stock options. The Compensation Committee attempts to combine these
components in such a way as to attract, motivate and retain key executives
critical to the long-term success of the Company. A discussion of the various
components of the executives' compensation for fiscal 1998 follows.
 
     Base Salary. Each executive officer received a base salary and has the
potential for annual salary increases largely determined by such individual's
performance, the Company's performance and reference to the salaries of
executive officers holding comparable positions in companies of comparable size
and complexity.
 
                                       12
<PAGE>   26
 
     Bonuses. Each executive officer was eligible for an annual bonus based upon
both his individual performance and the Company's performance. Bonuses will be
awarded to executive officers with respect to fiscal 1998 taking into account
their performance and the Company's performance.
 
     Stock Options. The Company's 1993 and 1995 Stock Option Plans are intended
to provide executives with the promise of longer term rewards which appreciate
in value with the favorable future performance of the Company. Stock options are
generally granted when an executive joins the Company, with additional options
granted from time to time for promotions and performance. The Compensation
Committee believes that the stock option participation provides a method of
retention and motivation for the executives of the Company and also aligns
senior management's objectives with long-term stock price appreciation.
 
     Other Compensation. The executive officers also participate in the
Company's 401(k) plan as well as the medical, life and disability insurance
plans available to all employees of the Company.
 
CHIEF EXECUTIVE OFFICER COMPENSATION
 
     The compensation of Mr. Meckler, Chairman of the Board and Chief Executive
Officer of the Company, and proposals for additional compensation to him are
based on the policies described above. As part of its evaluation, the
Compensation Committee considered Mr. Meckler's performance, the Company's
performance, the accomplishment of goals for the Company set by the Board of
Directors at the beginning of fiscal 1998, and the compensation earned by other
chief executive officers of companies of comparable size during the previous
year.

                                          Beverly C. Chell
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During the last completed fiscal year, Messrs. Martino and Davies and Ms.
Chell served as members of the Compensation Committee. None of such members of
the Compensation Committee are or have been officers or employees of the
Company.

                     CERTAIN RELATIONSHIPS AND TRANSACTIONS
 
     Pursuant to the terms of an August 1993 stock purchase agreement ( the
"Stock Purchase Agreement"), the Company has granted certain "piggyback"
registration rights (that is, rights to include shares in a registration
statement otherwise filed by the Company, at the Company's expense) to (i) James
S. Mulholland, Jr., James S. Mulholland III, certain other existing stockholders
who received their stock in transfers from either of them and certain classes of
future transferees of Common Stock originally purchased by the Mulhollands on
August 2, 1993, pursuant to the Stock Purchase Agreement (together with Messrs.
Mulholland Jr. and Mulholland III, the "Mulholland Family") and (ii) Alan M.
Meckler, certain other existing stockholders who received their Common Stock in
transfers from Mr. Meckler and certain classes of future transferees of Common
Stock owned by Mr. Meckler on the date of the Stock Purchase Agreement (together
with Mr. Meckler, the "Meckler Family"). Pursuant to an exercise of the
"piggyback" registration rights provided by the Stock Purchase Agreement,
Messrs. Meckler and Mulholland III and certain other stockholders, included in
the aggregate, 448,750 shares of Common Stock (prior to adjustment for the
two-for-one stock split of the Company's Common Stock on September 19, 1995) in
a registration statement filed by the Company with respect to a public offering
in August 1995.
 
     The Stock Purchase Agreement also provides that if the Meckler Family
transfers not less than 40% of the aggregate amount of Common Stock held by
them, then Mr. Meckler, the Meckler Family or the acquirer of such Common Stock
has the right (the "take-along right") to require the Mulholland Family to
transfer a like percentage of Common Stock held by them on the same terms and
subject to the same conditions. The take-along
 
                                       14
<PAGE>   28
 
right will terminate upon the earlier of February 11, 1999, or the date upon
which the aggregate amount of Common Stock held by the Meckler Family is less
than that held by the Mulholland Family.
 
     Wayne A. Martino, a director of the Company since December 1993, is a
principal in the law firm of Brenner, Saltzman, counsel to the Company. The
Company paid legal fees and expenses of approximately $12,000, $36,000 and
$74,000 to Brenner, Saltzman for its services in fiscal 1998, fiscal 1997 and
fiscal 1996, respectively.
 
                      COMPLIANCE WITH SECTION 16(a) OF THE
                        SECURITIES EXCHANGE ACT OF 1934
 
     Section 16 (a) of the Securities Exchange Act of 1934, as amended, requires
the Company's executive officers and directors, and greater than 10%
stockholders to file reports of ownership and changes in ownership of the
Company's securities with the Securities and Exchange Commission ("SEC").
Specific due dates for these reports have been established by the SEC, and the
Company is required to disclose in this Proxy Statement any failure by such
persons to file these reports in a timely manner during the 1997 fiscal year.
Copies of the reports are required by SEC regulation to be furnished to the
Company. Based on its review of such reports furnished to it, the Company
believes that there were no late filings during the fiscal year ended September
30, 1998.

                  AGREEMENT AND PLAN OF MERGER, dated as of October 7, 1998
(this "AGREEMENT"), among Mecklermedia Corporation, a Delaware corporation (the
"COMPANY"), Penton Media, Inc., a Delaware corporation (the "PURCHASER"),
Internet World Media, Inc., a Delaware corporation and a wholly owned subsidiary
of the Purchaser ("MERGER SUB") and Alan M. Meckler, an individual (the
"Stockholder").

                               W I T N E S S E T H

                  WHEREAS, the Boards of Directors of the Company and the
Purchaser have each determined that it is in the best interests of their
respective stockholders for the Purchaser to acquire the Company upon the terms
and subject to the conditions set forth herein; and

                  WHEREAS, in furtherance thereof, it is proposed that the
Purchaser will make a cash tender offer (the "OFFER") to purchase all of the
issued and outstanding shares of common stock, $.01 par value, of the Company
(the "SHARES"), for $29.00 per Share (the "PER SHARE AMOUNT"), or such higher
price as may be paid in the Offer, net to the seller in cash; and

                  WHEREAS, also in furtherance thereof, the Boards of Directors
of the Company, the Purchaser and Merger Sub have each approved the merger (the
"MERGER") of Merger Sub with and into the Company following the Offer in
accordance with the General Corporation Law of the State of Delaware ("DELAWARE
LAW") and upon the terms and subject to the conditions set forth herein; and

                  WHEREAS, the Board of Directors of the Company (the "BOARD OF
DIRECTORS") has unanimously resolved to recommend acceptance of the Offer and
the Merger to the holders of Shares and has determined that the consideration to
be paid for each Share in the Offer and the Merger is fair to the holders of
such Shares and to recommend that the holders of such Shares accept the Offer
and approve the Merger, this Agreement and the transactions contemplated hereby;
and

                  WHEREAS, in order to induce Purchaser and Merger Sub to enter
into this Agreement, concurrently with the execution and delivery hereof,

and Option Agreement dated the date hereof (the "Voting and Option Agreement").

                  NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements herein contained, and 






<PAGE>   7

intending to be legally bound hereby, the Company, the Purchaser and Merger Sub
hereby agree as follows:


                                   ARTICLE I.

                                THE TENDER OFFER

                  SECTION 1.1.  THE OFFER.

                  (a) Provided that this Agreement shall not have been
terminated in accordance with Section 8.1 hereof and none of the events set
forth in Annex I hereto shall have occurred and be continuing, the Purchaser or
Merger Sub shall commence (within the meaning of Rule 14d-2 under the Securities
Exchange Act of 1934, as amended (the "EXCHANGE ACT") the Offer as promptly as
practicable, but in no event later than five business days following the
execution of this Agreement, and, subject to the conditions of the Offer, shall
use all reasonable efforts to consummate the Offer. The obligation of the
Purchaser to consummate the Offer and to accept for payment any Shares tendered
pursuant thereto shall be subject to the satisfaction of only those conditions
set forth in Annex I. The Purchaser expressly reserves the right to waive any
such condition or to increase the Per Share Amount. The Per Share Amount shall
be net to the seller in cash, subject to reduction only for any applicable
Federal back-up withholding or stock transfer taxes payable by the seller. The
Company agrees that no Shares held by the Company will be tendered pursuant to
the Offer.

                  (b) Without the prior written consent of the Company, the
Purchaser shall not (i) decrease the Per Share Amount or change the form of
consideration payable in the Offer, (ii) decrease the number of Shares sought,
(iii) amend or waive satisfaction of the Minimum Condition (as defined in Annex
I) or (iv) impose additional conditions to the Offer or amend any other term of
the Offer in any manner adverse to the holders of Shares; PROVIDED HOWEVER, that
if on the initial expiration date of the Offer, which shall be November 18,
1998 (together with any extensions thereof, if any, the "EXPIRATION DATE"), all
conditions to the Offer shall not have been satisfied or waived, the Purchaser
may extend the Expiration Date up to an additional six (6) business days to the
extent necessary to permit such condition to be satisfied; provided, further, 
however, that the Expiration Date may not be extended beyond November 27, 1998,
except with the written consent of the Company. The Purchaser shall, on the 
terms and subject to the prior satisfaction or waiver of the conditions of the 
Offer, accept for payment and purchase, as soon as permitted under the terms of
the Offer, all Shares validly tendered and not withdrawn prior to the 
expiration of the Offer.


                  (c) The Offer shall be made by means of an offer to purchase
(the "OFFER TO PURCHASE") having only the conditions set forth in Annex I
hereto. As soon as practicable on the date the Offer is commenced, the Purchaser
shall file with the Securities 

                                      (2)
<PAGE>   8



and Exchange Commission (the "SEC") a Tender Offer Statement on Schedule 14D-1
(together with all amendments and supplements thereto, the "SCHEDULE 14D-1")
with respect to the Offer that will comply in all material respects with the
provisions of, and satisfy in all material respects the requirements of, such
Schedule 14D-1 and all applicable Federal securities laws, and will contain
(including as an exhibit) or incorporate by reference the Offer to Purchase and
forms of the related letter of transmittal and summary advertisement (which
documents, together with any supplements or amendments thereto, and any other
SEC schedule or form which is filed in connection with the Offer and related
transactions, are referred to collectively herein as the "OFFER DOCUMENTS").
Each of the Purchaser, Merger Sub and the Company agrees promptly to correct any
information provided by it for use in the Schedule 14D-1 or the Offer Documents
if and to the extent that it shall have become false or misleading in any
material respect and to supplement the information provided by it specifically
for use in the Schedule 14D-1 or the Offer Documents to include any information
that shall become necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading, and the Purchaser
further agrees to take all steps necessary to cause the Schedule 14D-1, as so
corrected or supplemented, to be filed with the SEC and the Offer Documents, as
so corrected or supplemented, to be disseminated to holders of Shares, in each
case as and to the extent required by applicable Federal securities laws. The
Company and its counsel shall be given a reasonable opportunity to review and
comment on any Offer Documents before they are filed with the SEC.


                  SECTION 1.2.  COMPANY ACTION.

                  (a) The Company hereby approves of and consents to the Offer
and represents and warrants that (i) the Board of Directors, at a meeting duly
called and held on October 7, 1998, at which a majority of the Directors were
present, unanimously and duly approved and adopted this Agreement and the
transactions contemplated hereby, including the Offer and the Merger (such
approval being sufficient to render Section 203 of Delaware Law inapplicable to
this Agreement and the transactions contemplated hereby, including the Offer and
the Merger), recommended that the stockholders of the Company accept the Offer,
tender their Shares pursuant to the Offer and approve this Agreement and the
transactions contemplated hereby, including the Merger, and determined that this
Agreement and the transactions contemplated hereby, including the Offer and the
Merger, are fair to and in the best interests of the stockholders of the Company
and (ii) Allen & Company, Inc., the Company's financial advisor, has rendered to
the Board of Directors its opinion that the consideration to be received by the
holders of Shares, Options and Warrants of the Company pursuant to the Offer and
the Merger is fair to such holders from a financial point of view.

                                      (3)
<PAGE>   9


                  (b) The Company shall file with the SEC, simultaneously with
(or at such later date as may be mutually agreed between the Company and
Purchaser) the filing by the Purchaser of the Schedule 14D-1 with respect to the
Offer, a Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9
(together with any amendments or supplements thereto, the "SCHEDULE 14D-9") that
will comply in all material respects with the provisions of all applicable
Federal securities laws. The Company shall mail such Schedule 14D-9 to the
stockholders of the Company along with the Offer Documents promptly after the
commencement of the Offer. The Schedule 14D-9 and the Offer Documents shall
contain the recommendations of the Board of Directors described in Section
1.2(a) hereof. The Company agrees promptly to correct the Schedule 14D-9 if and
to the extent that it shall become false or misleading in any material respect
(and each of the Purchaser and Merger Sub, with respect to written information
supplied by it specifically for use in the Schedule 14D-9, shall promptly notify
the Company of any required corrections of such information and cooperate with
the Company with respect to correcting such information) and to supplement the
information contained in the Schedule 14D-9 to include any information that
shall become necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, and the Company shall
take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed
with the SEC and disseminated to the Company's stockholders to the extent
required by applicable Federal securities laws. The Purchaser and its counsel
shall be given a reasonable opportunity to review and comment on the Schedule
14D-9 before it is filed with the SEC.

                  (c) In connection with the Offer, the Company shall promptly
upon execution of this Agreement furnish the Purchaser with mailing labels
containing the names and addresses of all record holders of Shares and security
position listings of Shares held in stock depositories, each as of a recent
date, and shall promptly furnish the Purchaser with such additional information,
including updated lists of stockholders, mailing labels and security position
listings, and such other information and assistance as the Purchaser or its
agents may reasonably request for the purpose of communicating the Offer to the
record and beneficial holders of Shares.

                  SECTION 1.3. DIRECTORS.

                  (a) Promptly upon the purchase by the Purchaser of any Shares
pursuant to the Offer, and from time to time thereafter as Shares are acquired
by the Purchaser, the Purchaser shall be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors as
will give the Purchaser, subject to compliance with Section 14(f) of the
Exchange Act, representation on the Board of Directors equal to at least that
number of directors which equals the product of the total number of directors on
the Board of Directors (giving 


                                      (4)

<PAGE>   10

effect to the directors appointed or elected pursuant to this sentence and
including current directors serving as officers of the Company) multiplied by
the percentage that the aggregate number of Shares beneficially owned by the
Purchaser or any affiliate of the Purchaser (including for purposes of this
Section 1.3 such Shares as are accepted for payment pursuant to the Offer, but
excluding Shares held by the Company) bears to the number of Shares outstanding.
At such times, if requested by the Purchaser, the Company will also cause each
committee of the Board of Directors to include persons designated by the
Purchaser constituting the same percentage of each such committee as the
Purchaser's designees are of the Board of Directors. The Company shall, upon
request by the Purchaser, promptly increase the size of the Board of Directors
or exercise its best efforts to secure the resignations of such number of
directors as is necessary to enable the Purchaser designees to be elected to the
Board of Directors in accordance with the terms of this Section 1.3 and shall
cause the Purchaser's designees to be so elected; PROVIDED, HOWEVER, that, in
the event that the Purchaser's designees are appointed or elected to the Board
of Directors, until the Effective Time (as defined in Section 2.2 hereof) the
Board of Directors shall have at least one director who is a director on the
date hereof and who is neither an officer of the Company nor a designee,
stockholder, affiliate or associate (within the meaning of the Federal
securities laws) of the Purchaser (one or more of such directors, the
"INDEPENDENT DIRECTORS"); PROVIDED FURTHER, that if no Independent Directors
remain, the other directors shall designate one person to fill one of the
vacancies who shall not be either an officer of the Company or a designee,
shareholder, affiliate or associate of the Purchaser, and such person shall be
deemed to be an Independent Director for purposes of this Agreement.

                  (b) Subject to applicable law, the Company shall promptly take
all action necessary pursuant to Section 14(f) of the Exchange Act and Rule
14f-1 promulgated thereunder in order to fulfill its obligations under this
Section 1.3 and shall include in the Schedule 14D-9 mailed to stockholders
promptly after the commencement of the Offer (or an amendment thereof or an
information statement pursuant to Rule 14f-1 if the Purchaser has not
theretofore designated directors) such information with respect to the Company
and its officers and directors as is required under Section 14(f) and Rule 14f-1
in order to fulfill its obligations under this Section 1.3. The Purchaser will
supply the Company and be solely responsible for any information with respect to
itself and its nominees, officers, directors and affiliates required by Section
14(f) and Rule 14f-1. Notwithstanding anything in this Agreement to the
contrary, prior to the Effective Time, the affirmative vote of a majority of the
Independent Directors shall be required to (i) amend or terminate this Agreement
on behalf of the Company, (ii) exercise or waive any of the Company's rights or
remedies hereunder, (iii) extend the time for performance of the Purchaser's
obligations hereunder 


                                      (5)
<PAGE>   11

or (iv) take any other action by the Company in connection with this Agreement
required to be taken by the Board of Directors.


                                   ARTICLE II.

Surviving Corporation its right, title or interest in, to or under any of the
rights, properties or assets of either of the Company or Merger Sub acquired or
to be acquired by the Surviving Corporation as a result of, or in connection
with, the Merger or otherwise to carry out this Agreement, the

<PAGE>   12

officers and directors of the Surviving Corporation shall be authorized to
execute and deliver, in the name and on behalf of either the Company or Merger
Sub, all such deeds, bills of sale, assignments and assurances and to take and

Agreement.

                  SECTION 2.5. CERTIFICATE OF INCORPORATION; BY-LAWS; DIRECTORS
AND OFFICERS.

                  (a) Unless otherwise determined by the Purchaser before the

Certificate of Incorporation of the Surviving Corporation (as the same may be

Company, including any such amendment as shall be required for Purchaser to

provided by law and such Certificate of Incorporation.

any office of the Surviving Corporation, such vacancy may thereafter be filled

<PAGE>   13


and retired and will cease to exist, and each holder of a certificate formerly
representing any such Share will cease to have any rights with respect thereto,

common stock, par value $.Ol per share, of the Surviving Corporation.

                  SECTION 2.7.  DISSENTING SHARES.

                  (a) Notwithstanding any provision of this Agreement to the
contrary, any Shares held by a holder who has demanded and perfected his demand
for appraisal of his Shares in accordance with Delaware Law (including but not
limited to ss.262 thereof) and as of the Effective Time has neither effectively
withdrawn nor lost his right to such appraisal ("DISSENTING SHARES"), shall not
be converted into or represent a right to receive cash pursuant to Section 2.6,
but the holder thereof shall be entitled to only such rights as are granted by
Delaware Law.

                  (b) Notwithstanding the provisions of Section 2.7(a), if any
holder of Shares who demands appraisal of his Shares under Delaware Law shall
effectively withdraw or lose (through failure to perfect or otherwise) his right
to appraisal, then as of the Effective Time or the occurrence of such event,
whichever later occurs, such holder's Shares shall automatically be converted
into and represent only the right to receive cash as provided in Section 2.6(a),
without interest thereon, upon surrender of the certificate or certificates
formerly representing such Shares.

                  (c) The Company shall give the Purchaser (i) prompt notice of
any written demands for appraisal or payment of the fair value of any Shares,
withdrawals of such demands, and any other instruments served pursuant to
Delaware Law received by the Company and (ii) the opportunity to direct all
negotiations and proceedings with respect to demands for appraisal under
Delaware Law. The Company shall not voluntarily make any payment with respect to
any demands for appraisal and shall not, except with the prior written consent
of the Purchaser, settle or offer to settle any such demands.

                  (a) Before the Effective Time, the Purchaser shall designate a
bank or trust company reasonably acceptable to the Company to act as agent for

the Effective Time, the Purchaser shall deposit, or cause to be deposited, in
trust with the Exchange Agent for the benefit of holders of Shares the aggregate
consideration to which such holders shall be entitled at the Effective Time
pursuant to Section 2.6.

                  (b) Each holder of a certificate or certificates representing
any Shares canceled upon the Merger pursuant to Section 2.6(a) (the
"CERTIFICATE(S)") may thereafter surrender such certificate or certificates to
the Exchange Agent, as agent for such holder, to effect the surrender of such
Certificate or Certificates on such holder's behalf for a period ending one year
after the Effective Time. The Purchaser agrees that promptly after the Effective
Time it shall cause the distribution to holders of record of Shares as of the
Effective Time of appropriate materials to facilitate such surrender. Upon the
surrender of Certificates for cancellation, together with such materials, the
Purchaser shall cause the Exchange Agent to pay the holder of such Certificates
in exchange therefor cash in an amount equal to the Per Share Amount multiplied
by the number of Shares represented by such Certificate. Until so surrendered,
each such Certificate (other than Certificates representing Dissenting Shares
and Certificates representing Shares held by the Purchaser or in the treasury of
the Company) shall represent solely the right to receive the aggregate Per Share
Amount relating thereto.

                  (c) If payment of cash in respect of canceled Shares is to be
made to a Person other than the Person in whose name a surrendered Certificate
or instrument is registered, it shall be a condition to such payment that the
Certificate or instrument so surrendered shall be properly endorsed or shall be
otherwise in proper form for transfer and that the Person requesting such
payment shall have paid any transfer and other taxes required by reason of such
payment in a name other than that of the registered holder of the Certificate or
instrument surrendered or shall have established to the satisfaction of the
Purchaser or the Exchange Agent that such tax either has been paid or is not
payable.

                  (d) At the Effective Time, the stock transfer books of the
Company shall be closed and there shall not be any further registration of
transfers of shares of any shares of capital stock thereafter on the records of
the Company. If, after the Effective Time, Certificates are presented to the
Surviving Corporation, they shall be canceled and exchanged for cash as 

                                      (9)
<PAGE>   15



provided in Section 2.6(a). No interest shall accrue or be paid on any cash
payable upon the surrender of a Certificate or Certificates which immediately
before the Effective Time represented outstanding Shares.

                  (e) Promptly following the date which is one year after the
Effective Time, the Exchange Agent shall deliver to the Purchaser all cash,
certificates and other documents in its possession relating to the transactions
contemplated hereby, and the Exchange Agent's duties shall terminate.
Thereafter, each holder of a Certificate (other than Certificates representing
Dissenting Shares and Certificates representing Shares held by the Purchaser or
in the treasury of the Company) may surrender such Certificate to the Purchaser
and (subject to applicable abandoned property, escheat and similar laws) receive
in consideration thereof the aggregate Per Share Amount relating thereto,
without any interest or dividends thereon.

                  (f) The Per Share Amount paid in the Merger shall be net to
the holder of Shares in cash, subject to reduction only for any applicable
federal back-up withholding or, as set forth in Section 2.8(c), stock transfer
taxes payable by such holder.

                  (g) In the event any Certificate has been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the Person claiming
such Certificate to be lost, stolen or destroyed, the Exchange Agent will issue
in exchange for such lost, stolen or destroyed Certificate the Per Share Amount
deliverable in respect thereof as determined in accordance with Section 2.6;
provided that the Person to whom the Per Share Amount is paid shall, as a
condition precedent to the payment thereof, give the Surviving Corporation a
bond in such sum as the Surviving Corporation may direct or otherwise indemnify
the Surviving Corporation in a manner satisfactory to it against any claim that
may be made against the Surviving Corporation with respect to the Certificate
claimed to have been lost, stolen or destroyed.

                  SECTION 2.9.  STOCK PLANS AND WARRANT AGREEMENTS.

                  (a) The Company shall use all reasonable efforts (which
include, but are not limited to, satisfying the requirements of Rule 16b-3(e)
which is promulgated under Section 16 of the Exchange Act, without incurring any
liability in connection therewith) to provide that, upon consummation of the
Merger, (i) each then outstanding option to purchase Shares (the "OPTIONS")
granted under any of the Company's stock option plans referred to in Section
4.2, each as amended (collectively, the "OPTION PLANS"), and (ii) each then
outstanding warrant to purchase Shares (the "WARRANTS") granted under any of the
warrant agreements referred to in Section 4.2, each as amended (collectively,
the "WARRANT AGREEMENTS"), whether or not then exercisable or vested, shall be
acquired by the Company for cancellation in consideration of payment to the
holders of such Options and Warrants of an amount in respect thereof equal to
the 

                                      (10)
<PAGE>   16


product of (A) the excess, if any, of the Per Share Amount over the per share
exercise price thereof and (B) the number of Shares subject thereto (such
payment to be net of applicable withholding taxes); provided that the Company
shall obtain any consents required of holders of Options and Warrants to effect
the foregoing. As promptly as practicable following the consummation of the
Offer, the Purchaser shall provide the Company with the funds necessary to pay
in full the consideration payable to holders of Options and Warrants under this
Section 2.9(a).

                  (b) Except as provided herein or as otherwise agreed to by the
parties, (i) the Company shall cause the Option Plans and Warrant Agreements to
terminate as of the Effective Time and (ii) the Company shall ensure that
following the Effective Time no person, including any holder of Options or
Warrants or any participant in the Option Plans, shall have any right to acquire
any equity securities of the Company, the Surviving Corporation or any
subsidiary thereof.


                                  ARTICLE III.

                      REPRESENTATIONS AND WARRANTIES OF THE

                            PURCHASER AND MERGER SUB

                  The Purchaser and Merger Sub represent and warrant to the
Company as follows:

                  SECTION 3.1. CORPORATE ORGANIZATION. Each of the Purchaser and
Merger Sub is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and has the corporate power and
authority and any necessary governmental authority to own, operate or lease the
properties that it purports to own, operate or lease and to carry on its
business as it is now being conducted.

                  SECTION 3.2. AUTHORITY RELATIVE TO THIS AGREEMENT. The
execution and delivery of this Agreement by the Purchaser and Merger Sub and the
consummation by the Purchaser and Merger Sub of the transactions contemplated
hereby have been duly authorized by all necessary corporate action on the part
of the Purchaser and Merger Sub and no other corporate proceeding is necessary
for the execution and delivery of this Agreement by the Purchaser or Merger Sub,
the performance by the Purchaser or Merger Sub of their respective obligations
hereunder and the consummation by the Purchaser or Merger Sub of the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by the Purchaser and Merger Sub and, assuming due authorization,
execution and delivery of this Agreement by the Company, constitutes a legal,
valid and binding obligation of each such corporation, enforceable against each
of them in accordance with its terms, except that (i) the enforceability hereof
may be subject to applicable bankruptcy, insolvency or other similar 

                                      (11)
<PAGE>   17



laws, now or hereinafter in effect, affecting creditors' rights generally, and
(ii) the availability of the remedy of specific performance or injunctive or
other forms of equitable relief may be subject to equitable defenses and would
be subject to the discretion of the court before which any proceeding therefor
may be brought.

                  SECTION 3.3.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

                  (a) The execution and delivery of this Agreement by the
Purchaser and Merger Sub do not, and the performance of this Agreement by the
Purchaser and Merger Sub will not, (i) conflict with or violate any law,
regulation, court order, judgment or decree applicable to the Purchaser or
Merger Sub or by which any of their property is bound or affected, (ii) violate
or conflict with either the Certificate of Incorporation or By-Laws of either
the Purchaser or Merger Sub, or (iii) result in any breach of or constitute a
default (or an event which with notice or lapse of time or both would become a
default) under, or give to others any rights of termination or cancellation of,
or result in the creation of a lien or encumbrance on any of the property or
assets of the Purchaser or Merger Sub pursuant to, any contract, instrument,
permit, license or franchise to which the Purchaser or Merger Sub is a party or
by which the Purchaser or Merger Sub or any of their property is bound or
affected; except in the case of clauses (i) and (iii) for conflicts, violations,
breaches or defaults that individually and in the aggregate would not have or
result in a material adverse effect on the business, results of operations or
financial condition of Purchaser and its Subsidiaries, taken as a whole, or be
reasonably expected to prevent or materially impair or delay the consummation by
Purchaser or Merger Sub of the transactions contemplated hereby (each a
"Purchaser Material Adverse Effect").

                  (b) Except for applicable requirements, if any, of the
Exchange Act, under Competition Laws (as defined below), and filing and
recordation of appropriate merger documents as required by Delaware Law, neither
the Purchaser nor Merger Sub is required to submit any notice, report or other
filing with any governmental authority, domestic or foreign, in connection with
the execution, delivery or performance of this Agreement or the consummation of
the transactions contemplated hereby, the failure of which to submit would have
a Purchaser Material Adverse Effect. No waiver, consent, approval or
authorization of any governmental or regulatory authority, domestic or foreign,
is required to be obtained or made by either the Purchaser or Merger Sub in
connection with its execution, delivery or performance of this Agreement the
failure of which to obtain or make would have a Purchaser Material Adverse
Effect. "Competition Laws" means statutes, rules, regulations, orders, decrees,
administrative and judicial doctrines, and other laws that are designed or
intended to prohibit, restrict or regulate actions having the purpose or effect
of monopolization, lessening of competition or restraint 


                                      (12)

of trade, and includes the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR Act") and, to the extent applicable, equivalent laws of the
European Union or the Member States thereof, Canada and any other country in
which the Company or its Subsidiaries has operations or derives revenue.

                  SECTION 3.4. FINANCING ARRANGEMENTS. The Purchaser has
received a commitment letter (the "Commitment Letter") from DLJ Capital Funding,
Inc., DLJ Bridge Finance, Inc. and Donaldson Lufkin & Jenrette Securities
Corporation (collectively, "DLJ") dated October 7, 1998, whereby DLJ has
committed, upon the terms and subject to the conditions set forth therein, to
provide debt financing to Purchaser in the amount of up to $325.0 million (the
"Financing"). Purchaser has delivered a complete and correct copy of such letter
as in effect on the date hereof to the Company. As of the date hereof, Purchaser
believes that the aggregate proceeds of the Financing will be sufficient to (i)
pay the Per Share Amount with respect to all outstanding Shares, Options (less
the exercise price thereof) and Warrants (less the exercise price thereof) and
to perform the obligations of Purchaser and Merger Sub hereunder and (ii)
together with cash available to the Surviving Corporation, perform the
obligations of the Surviving Corporation under this Agreement. Neither Purchaser
nor Merger Sub knows of any fact or circumstance that it believes will prevent
it from obtaining the Financing. In addition, Purchaser and Merger Sub represent
and warrant to the Company that the Information (as defined in the Commitment
Letter but excluding Information provided in writing to Purchaser or Merger Sub
by the Company), as supplemented as contemplated by the Commitment Letter, is
(or will be, in the case of Information made available after the date hereof)
complete and correct in all material respects and does not (or will not, as the
case may be) contain any untrue statement of a material fact or omit to state a
material fact necessary to make the statements contained therein not materially
misleading in light of the circumstances under which such statements were or are
made.

                  SECTION 3.5. NO PRIOR ACTIVITIES. Except for obligations or
liabilities incurred in connection with its incorporation or organization or the
negotiation and consummation of this Agreement and the transactions contemplated
hereby (including any financing), Merger Sub has not incurred any obligations or
liabilities, and has not engaged in any business or activities of any type or
kind whatsoever or entered into any agreements or arrangements with any Person
or entity.

                  SECTION 3.6. BROKERS. Except for DLJ, no broker, finder or
investment banker is entitled to any brokerage, finder's or other fee or
commission in connection with the transactions contemplated by this Agreement
based upon arrangements made by and on behalf of the Purchaser or Merger Sub
that is or will be payable by the Company or any of its Subsidiaries. Purchaser
and Merger Sub are solely responsible for the fees and expenses of DLJ.

                                      (13)
<PAGE>   19


                  SECTION 3.7. OFFER DOCUMENTS; PROXY STATEMENTS. (a) None of
the information supplied by the Purchaser, Merger Sub, their respective
officers, directors, representatives, agents or employees (the "PURCHASER
INFORMATION"), for inclusion in the Proxy Statement (as defined in Section 4.9),
or in any amendments thereof or supplements thereto, will, on the date the Proxy
Statement is first mailed to stockholders of the Company or at the time of the
Company Stockholders' Meeting (as defined in Section 4.9), contain any statement
which, at such time and in light of the circumstances under which it will be
made, will be false or misleading with respect to any material fact, or will
omit to state any material fact necessary in order to make the statements
therein not false or misleading or necessary to correct any statement in any
earlier communication with respect to the solicitation of proxies for the
Company Stockholders' Meeting which has become false or misleading. Neither the
Offer Documents nor any amendments thereof or supplements thereto will, at any
time the Offer Documents or any such amendments or supplements are filed with
the SEC or first published, sent or given to the Company's stockholders, contain
any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading. Notwithstanding the foregoing, the
Purchaser and Merger Sub do not make any representation or warranty with respect
to any information that has been supplied by the Company or its accountants,
counsel or other authorized representatives for use in any of the foregoing
documents. The Offer Documents and any amendments or supplements thereto will
comply as to form in all material respects with the provisions of the Exchange
Act and the rules and regulations thereunder.

                           (b) If required, the Rule 13e-3 Transaction Statement
on Schedule 13E-3 to be filed with the SEC under the Exchange Act and/or mailed
to the stockholders of the Company in connection with the Offer and the Merger
(including any amendment or supplement thereto, the "Schedule 13E-3") (i) will
not, at the date such Schedule 13E-3 is filed with the SEC and/or mailed to the
stockholders of the Company contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading and (ii) will comply in all material respects
with the provisions of the Exchange Act and the rules and regulations
thereunder; except that no representation is made by Purchaser or Merger Sub
with respect to statements made in the Schedule 13E-3 based on information
supplied by the Company specifically for inclusion therein.


                                   ARTICLE IV.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                                      (14)
<PAGE>   20


                  Except as set forth on the Disclosure Schedule to this
Agreement (the "DISCLOSURE SCHEDULE"), the Company hereby represents and
warrants to the Purchaser and the Merger Sub as follows:

                  SECTION 4.1. ORGANIZATION AND QUALIFICATION; SUBSIDIARIES. The
Company (i) is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and has the requisite corporate
power and authority and any necessary governmental authority to own, operate or
lease the properties that it purports to own, operate or lease and to carry on
its business as it is now being conducted, and (ii) is duly qualified as a
foreign corporation to do business, and is in good standing, in each other
jurisdiction where the character of its properties owned, operated or leased or
the nature of its activities makes such qualification necessary, except in the
case of clause (ii) for failures which, when taken together with all other such
failures, would not have a Company Material Adverse Effect (as defined below in
this Section 4.1). Section 4.1 of the Disclosure Schedule lists each of the
Company's Subsidiaries and their respective jurisdictions of incorporation or
organization. The term "SUBSIDIARY" means any corporation or other legal entity
of which the Company (either alone or through or together with any other
Subsidiary) owns, directly or indirectly, more than 50% of the stock or other
equity interests the holders of which are generally entitled to vote for the
election of the board of directors or other governing body of such corporation
or other legal entity. The term "COMPANY MATERIAL ADVERSE EFFECT" means any
change in or effect on the business of the Company that is or can be reasonably
expected to be materially adverse to the business, assets, properties (including
intangible properties), condition (financial or otherwise), results of
operations, prospects (other than changes in general economic conditions but
including changes in the industry in which the Company operates), liabilities or
regulatory status of the Company and the Subsidiaries taken as a whole. The
Company has previously delivered to Purchaser a complete and correct copy of
each of its Certificate of Incorporation and By-Laws, as currently in effect.

                  SECTION 4.2. CAPITALIZATION. (a) The authorized capital stock
of the Company consists of 35,000,000 shares of common stock, $.01 par value, of
the Company (the "Company Common Stock") and 1,000,000 shares of preferred
stock, $.01 par value, of the Company (the "COMPANY PREFERRED STOCK"). As of the
close of business on the date one business day prior to the date hereof, (i)
9,109,542 shares of Company Common Stock were issued and outstanding, all of
which were duly authorized, validly issued, fully paid and nonassessable, (ii)
260,000 shares of Company Common Stock were held in the treasury of the Company,
(iii) no shares of Company Preferred Stock were issued or outstanding, (iv)
1,200,000 shares of Company Common Stock were reserved for issuance under the
Company's employee stock option plans listed on Schedule 4.2(a) of the
Disclosure Schedule in the 

                                      (15)
<PAGE>   21


amounts stated in such schedule and (v) 4,500 shares of Company Common Stock
were reserved for issuance upon the exercise of currently outstanding warrants
issued under the warrant agreements listed on Schedule 4.2(a) of the Disclosure
Schedule. Except as disclosed in the SEC Reports (as defined below) or on
Schedule 4.2(a) of the Disclosure Schedule, there are no existing (i) options,
warrants, calls, preemptive rights, subscriptions or other rights, convertible
securities, agreements or commitments of any character obligating the Company or
any of its Subsidiaries to issue, transfer or sell any shares of capital stock
or other equity interest in, the Company or any of its Subsidiaries or
securities convertible into or exchangeable for such shares or equity interests,
(ii) contractual obligations of the Company or any of its Subsidiaries to
repurchase, redeem or otherwise acquire any capital stock of the Company or any
Subsidiary of the Company or (iii) voting trusts or similar agreements to which
the Company or any of its Subsidiaries is a party with respect to the voting of
the capital stock of the Company or any of its Subsidiaries.

                           (b) Except as set forth on Schedule 4.2(b) of the
Disclosure Schedule and except for directors' qualifying shares (i) all of the
outstanding shares of capital stock (or equivalent equity interests of entities
other than corporations) of each of the Company's Subsidiaries are beneficially
owned, directly or indirectly, by the Company and (ii) neither the Company nor
any of its Subsidiaries owns any shares of capital stock or other securities of,
or interest in, any other Person, or is obligated to make any capital
contribution to or other investment in any other Person.


                  SECTION 4.3. AUTHORITY RELATIVE TO THIS AGREEMENT. The Company
has the necessary corporate power and authority to enter into this Agreement
and, subject to obtaining any necessary stockholder approval of the Merger, to
carry out its obligations hereunder. The execution and delivery of this
Agreement by the Company and the consummation by the Company of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of the Company, subject to the approval of the Merger by the
Company's stockholders in accordance with Delaware Law. This Agreement has been
duly executed and delivered by the Company and, assuming the due authorization,
execution and delivery of this Agreement by Purchaser and Merger Sub,
constitutes a legal, valid and binding obligation of the Company, enforceable
against it in accordance with its terms, except that (i) the enforceability
hereof may be subject to applicable bankruptcy, insolvency or other similar
laws, now or hereinafter in effect, affecting creditors' rights generally, and
(ii) the availability of the remedy of specific performance or injunctive or
other forms of equitable relief may be subject to equitable defenses and would
be subject to the discretion of the court before which any proceeding therefor
may be brought..

<PAGE>   22


                  SECTION 4.4.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

                           (a) The execution and delivery of this Agreement by
the Company do not, and the performance of this Agreement by the Company will
not, (i) conflict with or violate any law, regulation, court order, judgment or
decree applicable to the Company or by which its property is bound or affected,
(ii) violate or conflict with the Certificate of Incorporation or By-Laws of the
Company, or (iii) except as set forth on Exhibit F, result in any breach of or
constitute a default (or an event which with notice or lapse of time of both
would become a default) under, or give to others any rights of termination or
cancellation of, or result in the creation of a lien or encumbrance on any of
the properties or assets of the Company pursuant to, any contract, instrument,
permit, license or franchise to which the Company is a party or by which the
Company or its property is bound or affected, except in the case of clauses (i)
and (iii) for conflicts, violations, breaches or defaults which, individually or
in the aggregate, would not have a Company Material Adverse Effect.

                           (b) Except for applicable requirements, if any, of
the Exchange Act, under Competition Laws, and filing and recordation of
appropriate merger or other documents as required by Delaware Law, "takeover" or
"blue sky" laws of various states, the Company is not required to submit any
notice, report or other filing with any governmental authority, domestic or
foreign, in connection with the execution, delivery or performance of this
Agreement or the consummation of the transactions contemplated hereby the
failure of which to submit would have a Company Material Adverse Effect. No
waiver, consent, approval or authorization of any governmental or regulatory
authority, domestic or foreign, is required to be obtained or made by the
Company in connection with its execution, delivery or performance of this
Agreement the failure of which to obtain or make would have a Company Material
Adverse Effect.

                  SECTION 4.5.  SEC FILINGS; FINANCIAL STATEMENTS.

                           (a) The Company has filed all forms, reports and
documents required to be filed with the Securities and Exchange Commission
("SEC") since January 1, 1995, and has heretofore delivered or made available to
the Purchaser, in the form filed with the SEC, its (i) Annual Reports on Form
10-K SB for the fiscal years ended September 30, 1995, 1996 and 1997, (ii)
Quarterly Reports on Form 10-Q for the quarters ended December 31, 1997, March
31, 1998 and June 30, 1998, (iii) all proxy statements relating to the Company's
meetings of stockholders (whether annual or special) held since October 1, 1995
and (iv) all other forms, reports or registration statements (other than reports
on Form 10-Q not referred to in clause (ii) above) filed by the Company with the
SEC pursuant to the Exchange Act since October 1, 1995 (collectively, whether
filed before, on or after 


                                      (17)
<PAGE>   23


the date hereof, the "SEC REPORTS"). The SEC Reports (i) were prepared in
accordance with the requirements of the Exchange Act and the Securities Act of
1933 (the "Securities Act"), as the case may be, and the applicable rules and
regulations of the SEC thereunder and (ii) did not at the time they were filed
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

                           (b) The consolidated financial statements contained
in the SEC Reports were prepared in accordance with United States generally
accepted accounting principles ("GAAP") applied on a consistent basis throughout
the periods involved (except as may be indicated in the notes thereto) and
fairly presented the consolidated financial position of the Company and its
Subsidiaries as at the respective dates thereof and the consolidated results of
operations and changes in financial position of the Company and its Subsidiaries
for the periods indicated, except that the unaudited interim financial
statements were or are subject to normal and recurring year-end adjustments
which should not be materially adverse to the Company and its Subsidiaries taken
as a whole.

                           (c) Except as reflected or reserved against in the
consolidated financial statements contained in the SEC Reports filed prior to
the date hereof or otherwise disclosed in the SEC Reports filed prior to the
date hereof, neither the Company nor any of its Subsidiaries has any liabilities
or obligations of any nature (whether accrued, absolute, contingent or
otherwise) which in the aggregate would have a Company Material Adverse Effect
or which would be required to be set forth in consolidated financial statements
in accordance with GAAP.

                  SECTION 4.6.  ABSENCE OF CERTAIN CHANGES OR EVENTS.

                  Since September 30, 1997, except as contemplated by this
Agreement or as set forth in the SEC Reports filed prior to the date hereof, (i)
the Company and its Subsidiaries have conducted their respective operations only
in the ordinary course consistent with past practices; (ii) there has not been:

                  (a) any change which would have a Company Material Adverse
Effect;

                  (b) any strike, picketing, work slowdown or other labor
disturbance having a Company Material Adverse Effect;

                  (c) any damage, destruction or loss (whether or not covered by
insurance) with respect to any of the assets of the Company having a Company
Material Adverse Effect;

                  (d) any redemption or other acquisition of Company Common
Stock by the Company or any declaration or payment of any 

                                      (18)
<PAGE>   24


dividend or other distribution in cash, stock or property with respect to
Company Common Stock, except for purchases heretofore made pursuant to the terms
of the Company's employee benefit plans before the date hereof;

                  (e) any change by the Company in accounting principles except
insofar as may have been required by a change in generally accepted accounting
principles and disclosed in the SEC Reports; and

                  (iii) the Company and its Subsidiaries have not taken action
that if taken after the date hereof would constitute a violation of Section 5.1
hereof.

                  SECTION 4.7. LITIGATION. Except as disclosed in the SEC
Reports filed prior to the date hereof, there are no claims, actions, suits,
proceedings or investigations of any nature pending or, to the knowledge of the

Employee Plans are and have been at all times in compliance in all respects with

nor would there be any such liability if such insurance policy was terminated on
the date hereof, and (B) no insurance company issuing any such policy is in
receivership, conservatorship, liquidation or similar proceeding and, to the
knowledge of the Company, no such proceedings with respect to any insurer are
imminent; (viii) no Employee Plan provides benefits, including, without
limitation, death or medical benefits, beyond termination of service or
retirement other than (A) coverage mandated by law, (B) death or retirement
benefits under any qualified Employee Plan, or (C) deferred compensation
benefits reflected on the books of the Company; (ix) except as disclosed in

employee (or dependents of such employee), or (B) accelerate the time of payment
or vesting, or increase the amount of compensation due to any employee, officer
or director of the Company; (x) except as disclosed in Schedule 4.8(b), any
amount that could be received (whether in cash or property or the vesting of

is a "disqualified individual" (as such term is defined in proposed Treasury
Regulation Section 1.280G-1) under any employment, severance or termination
agreement, other compensation arrangement or Employee Plan currently in effect
would not be characterized as an "excess parachute payment" (as such term is
defined in Section 280G(b)(1) of the Code); (xi) except as disclosed in Schedule
4.8(b), the disallowance of a deduction under Section 162(m) of the Code for
employee remuneration will not apply to any amount paid or payable by the

program, arrangement or understanding currently in effect; (xii) neither the
Company nor any ERISA Affiliate has any current or future liability with respect
to any "employee benefit plans" (within the meaning of Section 3(3) of ERISA),
other than the Employee Plans, previously maintained or contributed to by the

Purchaser pursuant to the Offer and prior to such time as Purchaser shall have
nominated and the Company shall have caused Purchaser's nominees to constitute a
majority of the Board of Directors (provided that the Company has complied with
the requirements set forth in Section 1.3 of this Agreement), the Company may,
in response to an unsolicited written proposal with respect to an Acquisition
Transaction from a third party that the Board of Directors determines, in its
good faith and reasonable judgment, after consultation with and the receipt of
the advice of its financial advisor and outside counsel, is a Superior Proposal,
(i) furnish information to, and negotiate, explore or otherwise engage in
substantive discussions with such third party, only if the Board of Directors
determines, in good faith and reasonable judgment after consultation with its
financial advisors and outside legal counsel, that failing to take such action
would create a reasonable possibility of a breach of the fiduciary duties of the
Board of Directors under applicable law and (ii) take and disclose to the
Company's stockholders a position with respect to the Merger or another
Acquisition Transaction proposal, or amend or withdraw such position, pursuant
to Rules 14d-9 and 14e-2 under the Exchange Act.

to the Offer and prior to such time as Purchaser shall have nominated and the
Company shall have caused Purchaser's nominees to constitute a majority of the
Board of Directors (provided that the Company has complied with the requirements
set forth in Section 1.3 of this Agreement), in response to an unsolicited
Acquisition Transaction proposal, if the Board of Directors determines, in its
good faith, reasonable judgment, after consultation with and the receipt of the
advice of its financial advisor and outside counsel, that such proposal is a
Superior Proposal and that failure to do any of the actions set forth in clauses
(i), (ii) or (iii) above would create a reasonable possibility of a breach of
the fiduciary duties of the Board of Directors under applicable law, the Board
of Directors may withdraw or modify its approval or recommendation of the Offer,
the Merger or this Agreement, approve or recommend an Acquisition Transaction,
cause the Company to enter into an Acquisition Agreement or terminate this
Agreement pursuant to Section 8.1(d)(iii); PROVIDED, however, that the Merger
Agreement may not be terminated until after the expiration of the Offer.

Acquisition Transaction and any actions taken pursuant to Section 5.2(a),
specifying the material terms and conditions of such proposed Acquisition
Transaction and (ii) keep Purchaser reasonably informed of the status of any
such request or proposed Acquisition Transaction. If any such inquiry or
proposal is in writing, the Company shall promptly deliver to Purchaser a copy
of such inquiry or proposal.

                  (d) For purposes of this Agreement, (i) "ACQUISITION
TRANSACTION" means (other than the transactions contemplated by this Agreement)
(x) a merger, consolidation or other business combination, share exchange, sale
of shares of capital stock, tender offer or exchange offer or similar
transaction involving the Company or any of its Subsidiaries, (y) acquisition in
any manner, directly or indirectly, of a material interest in any voting
securities of, or a material equity interest in a substantial portion of the
assets of, the Company or any of its Subsidiaries, including any single or
multi-step transaction or series of related transactions which is structured to
permit a third party to acquire beneficial ownership of a majority or greater
equity interest in the Company, or (z) the acquisition in any manner, directly

business or assets held for sale) of the Company and (ii) "SUPERIOR PROPOSAL"

capital stock or a material portion of the assets of 


                                      (35)

                              ADDITIONAL AGREEMENTS

                  SECTION 6.1. PROXY STATEMENT. (a) If required by applicable

stockholders, the Proxy Statement. The Proxy Statement shall contain the
recommendation of the Board of Directors that stockholders of the Company
approve and adopt this Agreement and approve the Merger and the other

Company Stockholders Meeting any event or circumstance relating to the Company
or any of its Subsidiaries or affiliates, or its or their respective officers or
directors, should be discovered by the Company that is required to be set forth
in a supplement to the Proxy Statement, the Company shall promptly inform

receipt of comments of, or any requests by, the SEC with respect to the Schedule

correspondence between such party (or its representatives) and the SEC (or its
staff) relating thereto. The Company, Purchaser and Merger Sub each agrees to
correct any information provided by it for use in the Schedule 13E-3 which shall
have become, or is false or misleading..

                  SECTION 6.2. MEETING OF STOCKHOLDERS OF THE COMPANY. (a) If
required by applicable law in order to consummate the Merger, following the
purchase of and payment for Shares by Purchaser pursuant to the Offer, the
Company shall promptly take all action necessary in accordance with Delaware Law
and its Certificate of Incorporation and By-Laws to convene the Company
Stockholders Meeting. The Company shall use its best efforts to 

                                      (36)
<PAGE>   42



solicit from stockholders of the Company proxies in favor of the Merger and
shall take all other action necessary or, in the reasonable opinion of the
Purchaser, advisable to secure any vote or consent of stockholders required by
Delaware Law to effect the Merger. The Purchaser agrees that it shall vote, or
cause to be voted, in favor of the Merger all Shares directly or indirectly
beneficially owned by it.

                  (b) Notwithstanding Section 6.2(a) hereof, in the event that
Purchaser, the Merger Sub or any other Subsidiary of Purchaser acquires at least
90% of the outstanding Shares pursuant to the Offer or otherwise, the parties
hereto agree, at the request of Purchaser or Merger Sub, to take all necessary
and appropriate action to cause the Merger to become effective in accordance
with Section 253 of Delaware Law without a meeting of stockholders of the
Company as soon as practicable after the acceptance for payment and purchase of
Shares by Purchaser pursuant to the Offer.

                  SECTION 6.3. ADDITIONAL AGREEMENTS. The Company, the Purchaser
and Merger Sub will each comply in all material respects with all applicable
laws and with all applicable rules and regulations of any governmental authority
in connection with its execution, delivery and performance of this Agreement and
the transactions contemplated hereby. Each of the parties hereto agrees to use
all reasonable efforts to obtain in a timely manner all necessary waivers,
consents and approvals and to effect all necessary registrations and filings,
and to use all reasonable efforts to take, or cause to be taken, all other
actions and to do, or cause to be done, all other things necessary, proper or
advisable to consummate and make effective as promptly as practicable the
transactions contemplated by this Agreement.

                  SECTION 6.4. NOTIFICATION OF CERTAIN MATTERS. The Company
shall give prompt notice to the Purchaser, and the Purchaser shall give prompt
notice to the Company, of (i) the occurrence or non-occurrence of any event
whose occurrence or non-occurrence would be likely to cause either (A) any
representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at any time from the date hereof to the
Effective Time or (B) any condition set forth in Annex I to be unsatisfied in
any material respect at any time from the date hereof to the date the Purchaser
purchases Shares pursuant to the Offer and (ii) any material failure of the
Company, the Purchaser or Merger Sub, as the case may be, or any officer,
director, employee or agent thereof, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder;
provided, however, that the delivery of any notice pursuant to this Section 6.4
shall not limit or otherwise affect the remedies available hereunder to the
party receiving such notice.

financial, operating and other data and information as the Purchaser or Merger
Sub, through the Purchaser Representatives, may reasonably request.

                  (b) The Purchaser agrees that it shall, and shall cause its
affiliates and each of their respective officers, directors, employees,
financial advisors, agents and other authorized representatives (the "PURCHASER
REPRESENTATIVES"), to hold in strict confidence all data and information
obtained by them from the Company (unless such information is or becomes
publicly available without the fault of any of the Purchaser Representatives or
public disclosure of such information is required by law in the opinion of
counsel to the Purchaser) and shall insure that the Purchaser Representatives do
not disclose such information to others without the prior written consent of the
Company. Notwithstanding anything herein to the contrary, the terms of the
Confidentiality Agreement, dated September 23, 1998 (the "CONFIDENTIALITY
AGREEMENT"), executed by the Purchaser shall remain in full force and effect.

                  (c) In the event of the termination of this Agreement, the
Purchaser shall, and shall cause its affiliates to, return promptly every
document furnished to them by the Company or any of its representatives in

defend and hold harmless, each Indemnified Party against any costs or expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages, liabilities and amounts paid in settlement in connection with any
claim, action, suit, proceeding or investigation, including without limitation
liabilities arising out of this transaction, to the extent that it was based on
the fact that such Indemnified Party is or was a director, officer or employee
of the Company and arising out of actions or omissions or alleged actions or
omissions occurring at or prior to the Effective Time, and in the event of any
such claim, action, suit, proceeding or investigation (whether arising before or
after the Effective Time), (i) the Company or the Surviving Corporation, as
applicable, shall pay the reasonable fees and expenses of counsel selected by
the Indemnified Parties, which counsel shall be reasonably satisfactory to the
Company or the Surviving Corporation, promptly as statements therefor are
received and (ii) the Company and the Surviving Corporation will cooperate in
the defense of any such matter; PROVIDED, HOWEVER, that neither the Company nor
the Surviving Corporation shall be liable for any settlement effected without
its written consent (which consent shall not be unreasonably withheld); and
FURTHER, PROVIDED, that neither the Company nor the Surviving Corporation shall
be obliged pursuant to this Section 6.8 to pay the fees and disbursements of
more than one counsel for all Indemnified Parties in any single action except to
the extent that, in the opinion of counsel for the Indemnified Parties, two or
more of such Indemnified Parties have conflicting interests in the 


                                      (39)

outcome of such action. For six years after the Effective Time, the Surviving
Corporation shall be required to maintain or obtain officers' and directors'
liability insurance covering the Indemnified Parties who are currently covered
by the Company's officers and directors liability insurance policy on terms not
less favorable than those in effect on the date hereof in terms of coverage and
amounts; provided, however, that the Surviving Corporation will not be required
to expend in any year an amount in excess of 200% of the annual aggregate
premiums currently paid by the Company for such insurance; and provided,
further, that if the annual premiums of such insurance coverage exceed such
amount, the Surviving Corporation will be obligated to obtain a policy with the
best coverage available, in the reasonable judgment of its Board of Directors,
for a cost not exceeding such amount. This Section 6.8 shall survive the
consummation of the Merger. The Purchaser shall cause Surviving Corporation to
reimburse all expenses, including reasonable attorney's fees and expenses,
incurred by any person to enforce the obligations of the Purchaser and the
Surviving Corporation under this Section 6.8. Notwithstanding Section 9.7
hereof, this Section 6.8 is intended to be for the benefit of and to grant third
party rights to Indemnified Parties whether or not parties to this Agreement,

contained herein.

assigns (i) consolidates with or merges into any other Person and shall not be
the continuing or surviving corporation or entity of such consolidation or
merger or (ii) transfers all or substantially all of its properties and assets
to any Person, then and in each such case, proper provision shall be made so

obligations set forth in this Section 6.8.

employer-provided benefits for nonunion employees under the Employee Plans as in
effect as of the Effective Time shall be continued under the same or an
equivalent plan and shall not be reduced for at least one year following the
Effective Time, except (i) to the extent provided in Section 2.9 hereof or (ii)
as required by applicable law (including as required to preserve any favorable
tax treatment afforded such benefits as of the Effective Time). Thereafter, such
participants shall in any event be credited with their service with the Company
in determining their right to participate and vesting under any successor
Employee Plans.

                  Section 6.10. RELATED AGREEMENTS. At the Effective Time, (i)
Purchaser shall cause (A) all assets (the "iWorld Assets") of iWorld

(B) the acquisition by the Stockholder and/or one or more Persons under his
control (such acquisition to be structured by the parties hereto so as to comply
with the Securities Act) of 80.1% of the equity interests in iWorld for an
aggregate purchase price of $18.0 million and (ii) (A) the agreement in
substantially the form attached hereto as Exhibit A (the "iWORLD AGREEMENT"),
(B) the Services Agreement between iWorld and Purchaser in substantially the
form attached hereto as Exhibit B, (C) the Trademark Licensing Agreement between
iWorld and Purchaser in substantially the form attached hereto as Exhibit C, (D)

substantially the form attached hereto as Exhibit D and (E) the Consulting
Agreement between Purchaser and the Stockholder in substantially the form
attached hereto as Exhibit E shall each be duly executed and delivered by the
parties thereto. Schedule 6.10 sets forth a substantially complete list of the
iWorld Assets. The Purchaser and the Company shall each use their best efforts
to reach a definitive agreement regarding which of the Company's assets shall
constitute all of the iWorld Assets.

                   Section 6.11. TRANSFER TAXES. The Purchaser and the Company
shall cooperate in the preparation, execution and filing of all returns,
applications or other documents regarding any real property transfer, stamp,
recording, documentary or other taxes (including, without limitation, any New
York State Real Estate Transfer Tax) and any other fees and similar taxes which
become payable in connection with the Merger (collectively, "TRANSFER TAXES").
From and after the Effective Date, the Purchaser shall pay or cause to be paid,
without deduction or withholding from any amounts payable to the holders of
Shares, all Transfer Taxes.

                   Section 6.12. FINANCIAL STATEMENTS; FINANCING. (a) The
Company shall provide to the Purchaser, no later than October 20, 1998,
unaudited financial statements (without accompanying notes) for the Company's

accompanying notes) for such fiscal year.

of this Agreement, the Company shall provide to the Purchaser or its
representatives such documentation and information as may reasonably be required
in connection with the Purchaser obtaining the Financing (including, if DLJ
deems it necessary, participation in road show presentations).

                  Section 6.13. Tax Indemnity. The Stockholder agrees to pay and
indemnify Purchaser for any liabilities arising from the Company's failure to
withhold amounts in respect of income taxes due as a result of the Stockholder's
exercise of options to purchase Company Common Stock.

granting such waiver in any other respect or at any other time. Neither the
waiver by any of the parties hereto of a breach of or a default under any of the
provisions of this Agreement, nor the failure by any of the parties, on one or
more occasions, to enforce any of the provisions of this Agreement or to
exercise any right or privilege hereunder, shall be construed as a waiver of any
other breach or default of a similar nature, or as a waiver of any of such
provisions, rights or privileges hereunder. The rights and remedies herein
provided are cumulative 

                                      (48)

                  (a) (i) Net Profits shall first be allocated in the order of,
in proportion to, and to the extent of, the excess of prior allocations of Net
Losses under SECTION 2.4(b)(ii) below over prior allocations of Net Profits
under this SECTION 2.4(a)(i) and, then, (ii) among the Members in proportion to
their Ownership Percentages.

                  (b) (i) Net Losses shall first be allocated among the Members

<PAGE>   65

                  (e) Notwithstanding the foregoing, allocations of Net Profit
and Net Loss in the taxable year of the Company in which winding up of the
Company commences, and in all subsequent years, shall be made to make the
Adjusted Capital Accounts of the Members stand in proportion to their respective
Ownership Percentages.

                  Section 2.5. SPECIAL ALLOCATIONS. Notwithstanding the general
allocation rules set forth in SECTION 2.4, the following special allocation
rules (the "Regulatory Allocations") shall apply under the circumstances
described therein:

                  (a) DEFICIT CAPITAL ACCOUNT AND NONRECOURSE DEBT RULES. The
special rules in this SECTION 2.5(a) apply, in the following order, to take into
account the possibility of Members having deficit Capital Account balances for
which they are not economically responsible and the effect of the Company or any
entity taxed as a partnership in which the Company has an ownership interest
incurring nonrecourse debt.

                  (i) PARTNERSHIP MINIMUM GAIN CHARGEBACK. If there is a net
decrease in "partnership minimum gain" during any year, to be determined in
accordance with Treasury Regulations ss. 1.704-2, including the tiered
partnership rules of Treasury Regulations ss. l.704-2(k), each Member shall be
allocated items of income and gain for such year equal to such Member's share of
the net decrease in partnership minimum gain within the meaning of Treasury
Regulations ss. l.704-2(g)(2), except to the extent not required by Treasury
Regulations ss. 1.704-2(f). To the extent that this SECTION 2.5(a)(i) is
inconsistent with Treasury Regulations ss. l.704-2(f) or 1.704-2(k) or
incomplete with respect to such regulations, the minimum gain chargeback
provided for herein shall be applied and interpreted in accordance with such
regulations.

                  (ii) PARTNERSHIP MINIMUM GAIN CHARGEBACK. If there is a net
decrease in "partner nonrecourse debt minimum gain" during any year, within the
meaning of Treasury Regulations ss. 1.704-2(i)(2), each Member who has a share
of the partner nonrecourse debt minimum gain attributable to such partner
nonrecourse debt, determined in accordance with Treasury Regulations ss.
1.704-2(i)(5), shall be allocated items of income and gain for such year (and,
if necessary, subsequent years) equal to such Member's share of the net decrease
in partner nonrecourse debt minimum gain. This allocation will be made in
accordance with Treasury Regulations ss. 1.704-2(i)(4) and 1.704-2(f)(5). To the
extent that this SECTION 2.5(a)(ii) is inconsistent with Treasury Regulations
ss. 1.704-2(i) or 1.704-2(k) or incomplete with respect to such regulations, the
partner nonrecourse debt minimum gain chargeback provided for herein shall be
applied and interpreted in accordance with such regulations.

<PAGE>   66

                  (iii) DEFICIT CAPITAL ACCOUNT CHARGEBACK AND QUALIFIED INCOME
OFFSET. If any Member has a deficit balance in its Capital Account at the end of
any year, including a deficit balance for such Member caused or increased by an
adjustment, allocation or distribution described in Treasury Regulations ss.
1.704-1(b)(2)(ii)(d)(4), (5) or (6), such Member shall be allocated items of
income and gain (consisting of a pro rata portion of each item of Company
income, including gross income and gain) in an amount and manner sufficient to
eliminate such deficit balance in its Capital Account as quickly as possible to
the extent required by Treasury Regulations ss. 1.704-1(b)(2)(ii). This SECTION
2.5(a)(iii) is intended to constitute a "qualified income offset" pursuant to
Treasury Regulations ss. 1.704-1(b)(2)(ii)(d) and shall be interpreted
consistently therewith.

                  (iv) PARTNER NONRECOURSE DEDUCTIONS. Any partner nonrecourse
deductions for any year or other period shall be allocated to the Member who
bears the economic risk of loss with respect to the partner nonrecourse debt to
which such partner nonrecourse deductions are attributable in accordance with
Treasury Regulations ss. 1.704-2(i) or 1.704-2(k).

                  (v) CURATIVE ALLOCATIONS. The Regulatory Allocations described
in this SECTION 2.5(a) may not be consistent with the manner in which the
Members intend to divide Net Profits, Net Losses and similar items. Accordingly,
Net Profits, Net Losses and other items will be reallocated among the Members
(in the same year and to the extent necessary, in subsequent years) in a manner
consistent with Treasury Regulations ss. 1.704-1(b) and 1.704-2 so as to prevent
the Regulatory Allocations from distorting the manner in which Net Profits, Net
Losses and other items are intended to be allocated among the Members pursuant
to SECTION 2.4 and in making such reallocations, account shall be taken of
future Regulatory Allocations that will in all likelihood occur.

                  (vi) SECTION 754 ADJUSTMENTS. To the extent an adjustment to
the adjusted tax basis of any Company asset pursuant to Section 734(b) or 743(b)
of the Code is required, pursuant to Treasury Regulations ss.
1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts,
the amount of such adjustment to the Capital Accounts shall be treated as an
item of profit (if the adjustment increases the basis of the asset) or loss (if
the adjustment decreases such basis) and such profit or loss shall be specially
allocated to the Member in a manner consistent with the manner in which their
Capital Accounts are required to be adjusted pursuant to such section of the
Treasury Regulations.

                  (b) CHANGE IN MEMBER'S INTEREST. If there is a change in any
Member's share of the Company's Net Profits, Net Losses or other items during
any year, allocations among the Members shall be made in accordance with their
interests in the Company from time to time during such year in accordance with

                                       7
<PAGE>   67

Section 706 of the Code, using the closing-of-the-books method, except that
depreciation, amortization and similar items shall be deemed to accrue ratably
on a daily basis over the entire year during which the corresponding asset is
owned by the Company for the entire year, and over the portion of a year after
such asset is placed in service by the Company if such asset is placed in
service during the year.

                  (c) NONRECOURSE DEBT SHARING. For purposes of this Agreement,
the Members shall be deemed to be allocated nonrecourse deductions, within the
meaning of Treasury Regulations ss. 1.704-2(b)(1), in accordance with their
proportionate number of Units. Solely for purposes of determining an Member's
proportionate share of the "excess nonrecourse liabilities" of the Company
within the meaning of Treasury Regulations ss. 1.752-3(a)(3), each Member's
interest in the Company profits is equal to the number of Units owned by such
Member divided by the number of outstanding Units.

                  Section 2.6.  RESTRICTIONS ON TRANSFERS.

                  (a) TRANSFER OF UNITS. (i) Except as expressly provided in
this Agreement, a Member may not sell, exchange, transfer, assign, pledge,
hypothecate or otherwise dispose of all or any portion of any of such Member's
Units or any interest therein (a "Transfer") (except for a Transfer by Internet
World to any Person or by any Member to a Permitted Transferee) without the
written consent of the Board, which consent may be withheld for any reason. The
Company shall not register any Transfer of a Member's Units or any interest
therein, and any such Transfer or registration of Transfer shall be null and
void, without the written consent of the Board. An assignee who has not been
admitted as a Member shall be entitled only to allocations and distributions
with respect to such interest in accordance with this Agreement, and shall have
no right to any information or, to the fullest extent permitted by law,
accounting of the affairs of the Company, shall not be entitled to inspect the
books or records of the Company and shall not have any of the rights of a Member
under the Act or this Agreement, but shall otherwise assume in writing prior to
such Transfer, other than a pledge (in respect of which such compliance shall be
required after sale or foreclosure), all obligations of the assignor hereunder
as if such assignee were the assignor; no such assignment shall be valid unless
the assumption of obligations described in this sentence has been executed.
Neither a Transfer of Units nor the admission of the Transferee thereof as a
Member shall discharge the transferor from any obligation hereunder.

                  (ii) The restrictions contained in this SECTION 2.6(a) shall
not apply with respect to any Transfer of Units or any part thereof by any
Member (a) among its Affiliates, (b) to any lender to whom a Member's Units or
any part thereof are assigned or pledged pursuant to a loan agreement, (c) to
any Member's spouse or children or to a trust or the trustee or 


                                       8
<PAGE>   68


trustees of a trust directly or indirectly for the benefit of the Member's
spouse, children or a charitable organization, (d) to the Member's executors,
administrator, testamentary trustee, legatees or beneficiaries upon the Member's
death, or (e) by gift (all such transferees shall be collectively referred to as
the "Permitted Transferees"); PROVIDED, that the Permitted Transferee shall
execute a counterpart of this Agreement; and PROVIDED, FURTHER that the
restrictions contained in this Agreement shall continue to apply to the Units
after such Transfer by reference to the original Member; and PROVIDED, FURTHER,
that the transferor shall remain liable for all of its obligations under this
Agreement that survive.

                  (b) RIGHTS OF FIRST REFUSAL. (i) In addition to the
restrictions contained in SECTION 2.6(A), no Member shall Transfer its Units or
any part thereof (other than to a Permitted Transferee) or exercise any
Drag-Along Right unless the Member desiring to make the Transfer or exercise
such Drag-Along Right (hereinafter referred to as the "Transferor") shall have
first made the offers to sell to the other Members (the "Other Members") as
contemplated by SECTION 2.6(b)(ii) through 2.5(b)(vii), and such offers shall
not have been accepted.

                  (ii) OFFER BY TRANSFEROR. Copies of the Transferor's offer
shall be given to all Other Members and shall consist of an offer to sell to
such Other Members all of the Units then proposed to be transferred by the
Transferor (the "Subject Units") pursuant to a bona fide offer of a third party,
other than an Affiliate of the Transferor, to which copies shall be attached a
statement of intention to Transfer to such third party, the name and address of
the prospective third party transferee, the portion of the Units involved in the
proposed Transfer, and terms of such Transfer which must include (A) all
consideration payable at closing and (B) that the offer is not contingent on any
event other than the non-acceptance of the Transferor's offer by the Other
Members.

                  (iii) ACCEPTANCE OF OFFER. Within 20 days after the receipt of
the offer described in SECTION 2.6(b)(ii), one or more of the Other Members (the
"Participating Other Members") may, at their option, elect to purchase all, but
not less than all, of the Subject Units, in such proportion per Participating
Other Member as shall be determined by the Participating Other Members;
PROVIDED, that should the Participating Other Members be unable to determine the
proportion of the Subject Units to be purchased by each within 20 days after the
receipt of the offer, each Participating Other Member which has not withdrawn
its election to purchase shall purchase a proportion of the Subject Units equal
to the Subject Units multiplied by the Ownership Percentage of such
Participating Other Member. The Participating Other Members shall exercise such
option by giving notice thereof to the Transferor within such 20-day period. The
notice required to be given by the Participating Other Members (the
"Purchasers") shall specify a date for the closing of the purchase which shall

                                       9
<PAGE>   69


not be more than 30 days after the date of the giving of such notice. In the
event that any party shall initiate an appraisal procedure pursuant to SECTION
2.6(b)(v) and (vi), such 20-day period shall be suspended as of (and including)
the date immediately following the date on which notice of such appraisal
procedure is given pursuant to SECTION 2.6(b)(v) and shall resume on (and
including) the date on which the appraisal procedure is completed pursuant to
SECTION 2.6(b)(vi).

                  (iv) PURCHASE PRICE. The purchase price for the Subject Units
shall be the price for the Subject Units offered to be paid by the prospective
transferee described in the offer, which price shall be paid in cash or, if
described in the offer of the prospective transferee, cash plus deferred
payments of cash in the same proportions, and with the same terms of deferred
payments, as therein set forth.

                  (v) CONSIDERATION OTHER THAN CASH. If the offer of a Subject
Units under this SECTION 2.6(b) is for consideration other than cash or cash
plus deferred payments of cash, the Purchaser shall pay the cash equivalent of
such other consideration. If the Transferor and the Purchaser cannot agree on
the amount of such cash equivalent within 10 days after the beginning of the
20-day period under SECTION 2.6(b)(iii), any of such parties may, by three days'
written notice to the other, initiate appraisal proceedings under SECTION
2.6(b)(vi) for determination of the cash equivalent. The Purchaser may give
written notice to the Transferor revoking an election to purchase the Subject
Units within 10 days after determination of the appraised value, if it chooses
not to purchase the Subject Units.

                  (vi) APPRAISAL PROCEDURE. If any party shall initiate an
appraisal procedure to determine the amount of the cash equivalent of any
consideration for a Subject Units under SECTION 2.6(b)(v), then the Transferor,
on the one hand, and the Purchaser, on the other hand, shall each promptly, but
in no event later than 10 days following written notice of such appraisal
procedure pursuant to SECTION 2.6(b)(v), appoint as an appraiser an individual
who shall be a member of a nationally-recognized investment banking firm. Each
appraiser shall, within 30 days of appointment, separately investigate the value
of the consideration for the Subject Units as of the proposed transfer date and
shall submit a notice of an appraisal of that value to each party. Each
appraiser shall be instructed to determine such value without regard to income
tax consequences to the Transferor as a result of receiving cash rather than
other consideration. If the appraised values of such consideration (the "Earlier
Appraisals") vary by less than 10%, the average of the two appraisals shall be
controlling as the amount of the cash equivalent. If the appraised values vary
by more than 10%, the appraisers, within 10 days of the submission of the last
appraisal, shall appoint a third appraiser who shall be a member of a nationally
recognized investment banking firm. The third appraiser shall, within 30 days of
his appointment, appraise the 

                                       10
<PAGE>   70



value of the consideration for the Subject Units (without regard to the income
tax consequences to the Transferor as a result of receiving cash rather than
other consideration) as of the proposed transfer date and submit notice of his
appraisal to each party. The value determined by the third appraiser shall be
controlling as the amount of the cash equivalent unless the value is greater
than the two Earlier Appraisals, in which case the higher of the two Earlier
Appraisals will control, and unless that value is lower than the two Earlier
Appraisals, in which case the lower of the two Earlier Appraisals will control.
If any party fails to appoint an appraiser or if one of the two initial
appraisers fails after appointment to submit his appraisal within the required
period, the appraisal submitted by the remaining appraiser shall be controlling.
The cost of the foregoing appraisals shall be shared one-half by the Transferor
and one-half by the Purchaser.

                  (vii) CLOSING OF PURCHASE. The closing of the purchase shall
take place at the office of the Company or such other location as shall be
mutually agreeable and the purchase price, in cash, shall be paid at the
closing. At the closing, the Transferor shall deliver to the Purchaser or
Purchasers documentation reasonably satisfactory to the Purchaser or Purchasers
evidencing the transfer of ownership of the Subject Units from the Transferor to
the Purchaser or Purchasers.

                  (c) RIGHT OF CO-SALE. In the event Meckler intends to Transfer
(i) all or part of his equity interest in the Company pursuant to an offering
registered under the Securities Act of 1933, as amended (the "Securities Act")
or (ii) Transfer at least 30% of his Units in any other transaction, other than
to a Permitted Transferee, Meckler shall notify each other Member, in writing,
of such Transfer and its terms and conditions. Within twenty (20) days of the
date of such notice, each Member shall notify Meckler if it elects to
participate in such Transfer. Each Member that so notifies Meckler shall have
the right to sell, at the same price and on the same terms as Meckler, a
percentage of such Member's Units equal to the percentage of Meckler's Units
that the third party actually proposes to purchase. For purposes of this SECTION
2.6(c) only, the term "Meckler" shall include Meckler and/or his Permitted
Transferees or Affiliates and/or their Permitted Transferees or Affiliates, as
the case may be, and the term "Member" shall not include Meckler or his
Affiliates.

                  (d) DRAG ALONG RIGHT. (i) Subject to SECTION 2.6(b), if, at
any time and from time to time after the date of this Agreement, Meckler wishes
to Transfer in a bona fide arms' length sale (for purposes of this SECTION
2.6(d), the "Proposed Transfer") 30% or more of his Units to any Person or
Persons who are not Affiliates of Meckler (for purposes of this SECTION 2.6(d),
the "Proposed Transferee"), Meckler shall have the right (for purposes of this
SECTION 2.6(d), the "Drag-Along Right") to require each Member to sell to the
Proposed Transferee all or a 


                                       11
<PAGE>   71


ratable portion of each such Member's Units, as the case may be, (for the same
proportional consideration received by Meckler, taking into account all
consideration received by Meckler under related agreements) then owned by such
Member. Each Member agrees to take all steps necessary to enable him or it to
comply with the provisions of this SECTION 2.6(d). For purposes of this SECTION
2.6(d) only, the term "Meckler" shall include Meckler and/or his Permitted
Transferees or Affiliates and/or their Permitted Transferees or Affiliates, as
the case may be, and the term "Member" shall not include Meckler or his
Affiliates, but only to the extent that Meckler or his Affiliates do not
participate in the Proposed Transfer.

                  (ii) To exercise a Drag-Along Right, Meckler shall comply with
SECTION 2.6(b) and, if the Other Members do not exercise their rights
thereunder, give each Member a written notice (for purposes of this SECTION
2.6(d), a "Drag-Along Notice") containing (i) the name and address of the
Proposed Transferee and (ii) the proposed purchase price, terms of payment and
other material terms and conditions of the Proposed Transferee's offer. Subject
to SECTION 2.6(b), each Member shall thereafter be obligated to sell its Units
subject to such Drag-Along Notice, PROVIDED, THAT the sale to the Proposed
Transferee is consummated within ninety (90) days of delivery of the Drag-Along
Notice. If the sale is not consummated within such 90-day period, then each
Member shall no longer be obligated to sell such Member's shares pursuant to
that specific Drag-Along Right but shall remain subject to the provisions of
this SECTION 2.6(d).

                  (iii) Notwithstanding anything contained in this SECTION
2.6(d), in the event that all or a portion of the purchase price consists of
securities and the sale of such securities to the Members would require either a
registration under the Securities Act or the preparation of a disclosure
document pursuant to Regulation D under the Securities Act (or any successor
regulation) or a similar provision of any state securities law, then, at the
Managing Member's option, the Members may receive, in lieu of such securities,
the fair market value of such securities in cash, as determined in good faith by
the Board.

                  Section 2.7. MANAGEMENT UNIT INCENTIVES. The Company may
authorize Units for grant or sale to key employees of the Company other than
Meckler (the "Option Units"), in such amounts and in such manner -- including
incentive and non-qualified Unit options, restricted Unit grants, Unit bonuses
or other option or incentive programs -- as the Managing Member shall determine
from time to time; PROVIDED, HOWEVER, that in no event shall the outstanding
Option Units exceed 4% of the Units outstanding on a fully diluted basis; and
provided, FURTHER, that it shall be a condition to the issuance of any Option
Units that the employee or other recipient, as the case may be, execute and
deliver to the Company and each party hereto a counterpart of this 

                                       12
<PAGE>   72


Agreement. Upon such execution and delivery, Exhibit A hereto shall be deemed to
be amended to include the name of such employee or other recipient, as the case
may be, and such employee or other recipient, as the case may be, shall be
deemed to be a Member for all purposes hereof. In the event a Member ceases to
own beneficially Option Units, such Member shall no longer be deemed a Member
for any purpose hereunder. The Ownership Percentage of each Member shall be
diluted proportionally by the issuance of any additional Units pursuant to this
SECTION 2.7.


                                  ARTICLE III.

                                   MANAGEMENT

                  Section 3.1.  MANAGEMENT BY THE MEMBERS.

                  (a) GENERAL PROVISIONS. The management of the Company shall be
vested in the Managing Member. Except as otherwise provided in this Agreement,
the Managing Member shall have all authority, rights and powers in the
management of the Company business to do any and all acts and things necessary,
proper, appropriate, advisable, incidental or convenient to effectuate the
purposes of this Agreement. Any action taken by the Managing Member on behalf of
the Company in accordance with the foregoing provisions shall constitute the act
of and shall serve to bind the Company.

                  (b) BOARD. (i) Certain actions by the Company, as further set
forth herein, shall be taken by the Company only upon approval by the Managing
Board (the "Board"), which shall be composed of three persons, consisting of (A)
two Persons (one of whom may be Meckler, and neither of whom need be Members)
designated by Meckler and (B) one Person (who need not be a Member) designated
by Internet World (collectively, "Board Members"). Each of Meckler and Internet
World shall reserve the right to remove and replace at any time any Board Member
that they have designated to sit on the Board pursuant to this SECTION
3.1(b)(i).

                  (ii) Meetings of the Board shall be held either within or
without the State of Delaware at such times and locations as may be determined
by the Managing Member. Notice of each meeting shall be given by the Managing
Member to each Board Member and shall state the place, date and time of the
meeting. Notice of such meeting shall be mailed, postage prepaid, to each Board
Member addressed to him at his address or usual place of business by first class
mail, at least two (2) days before the day on which such meeting is to be held,
or shall be sent addressed to such Board Member at such place by facsimile,
overnight courier, telex, or be delivered to him personally or by telephone, at

<PAGE>   73


                  (iii) A majority of the Board Members shall constitute a
quorum for the transaction of business. If a quorum shall not be present at any
meeting of the Board, the Board Members present thereat may adjourn the meeting
to another time and place. Notice of such time and place of the adjourned
meeting shall be given to all of the Board Members unless such time and place
were announced at the meeting at which the adjournment was taken, in which case
such notice shall only be given to the Board Members who were not present
thereat. At such adjourned meeting at which a quorum is present, any business
may be transacted which might have been transacted at the meeting as originally
called. Wherever approval by the Board is required by this Agreement, such
approval shall, except as otherwise set forth herein, consist of the affirmative
vote of a majority of the Board Members.

                  (iv) (A) Any action required or permitted to be taken by the
Board may be taken without a meeting if all the Board Members consent in
writing, and (B) one or more Board Members may participate in any meeting of the
Board by means of conference telephone or similar communications equipment by
means of which all persons participating in the meeting can hear each other, and
such participation in the meeting pursuant to this SECTION 3.1(b)(iv)(b) shall
constitute presence in person at the meeting.

                  (c) DELEGATION OF POWERS. The Managing Member may by
instrument in writing delegate its powers, but not its responsibilities, to
officers or agents or employees of the Company or of any Member or to any other
Person; PROVIDED, HOWEVER, that no Person shall be entitled to rely on such
delegation unless presented with a copy of such written instrument.

                  (d) BANK ACCOUNTS. The Managing Member shall cause the Company
to open and maintain bank accounts, and all funds of every kind and nature
received by the Company shall be deposited in such accounts. Signatories for
such accounts shall be authorized from time to time by the Managing Member.

                  Section 3.2. ADMISSION OF NEW MEMBERS; SALE OF ADDITIONAL
UNITS.

                  (a) Subject to SECTION 3.2(b), the Company may sell additional
Units on such terms and conditions as the Board shall from time to time
determine. The Ownership Percentage of each Member shall be diluted
proportionally by the issuance of any additional Units. All persons to whom
additional Units are sold shall be admitted as Members. In the event of the
admission of new or additional Members, EXHIBITS A and B hereto shall be amended
accordingly.

                  (b) In the event that the Company determines to issue any
Units, other than (i) pursuant to SECTION 2.7, (ii) the 

                                       14
<PAGE>   74



issuance of additional Units and admittance of additional Members in connection
with any acquisition, merger, reorganization or other business combination by or
involving the Company or (iii) in connection with any initial public offering of
the securities of the Company pursuant to a registration statement filed under
the Securities Act, the Company shall first offer to each Member the right to
subscribe for a portion of such Units in an amount equal to the product of (i)
the total number of Units to be issued by the Company pursuant to this SECTION
3.2(b) and (ii) a fraction, the numerator of which is the number of Units held
by such Member prior to such issuance, and the denominator of which is the total
number of Units held prior to such issuance by all Members other than Members
that acquired their interest pursuant to SECTION 2.7. For a period of 30 days
after such offer, each Member shall have the right, but not the obligation, to
acquire such Units. After the expiration of such 30 day period, the Company
shall have the right, during the 90 days after the expiration of the 30 day
period, to sell the unsubscribed portion of such Units to any third party on
terms (including payment terms) not less favorable to the Company than those on
which the Units were offered to the Members. If the Company is able to sell the
unsubscribed Units to third parties, or if all of the offered Units are
subscribed by Members, then each subscribing Member shall be obligated to, and
shall, purchase its subscribed portion of the offered Units. If the Company is
not able to sell the unsubscribed Units to third parties, or if all of the
offered Units are not subscribed by Members, respectively, then each subscribing
Member shall have the right, but not the obligation, to purchase its subscribed
portion of the offered Units on the terms of its subscription.

                  (c) Internet World may exercise its rights under the [Warrant
Agreement] dated ____, 1998 by and among Internet World, Meckler and the Company
(the "Warrant Agreement"). SECTION 3.2(b) shall not apply to any interest
acquired by Internet World pursuant to the Warrant Agreement.

                  Section 3.3. INDEMNIFICATION. Any Person made, or threatened
to be made, a party to any action or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that such Person is or
was (i) a Member, or (ii) an employee, officer, director, shareholder or partner
of a Member, or (iii) such other persons (including employees of the Company) as
the Board may designate from time to time, in its sole and absolute discretion
(collectively, the "INDEMNIFIED PERSONS"), shall be indemnified by the Company
for any losses or damage sustained with respect to such action or proceeding,
and the Company shall advance such Indemnified Person's reasonable related
expenses to the fullest extent permitted by law. The Company shall have the
power to purchase and maintain insurance on behalf of the Indemnified Persons
against any liability asserted against or incurred by them. The duty of the
Company to indemnify the Indemnified Persons under this SECTION 3.3 shall not
extend to actions or omissions of any Indemnified Person 


                                       15
<PAGE>   75

which are grossly negligent or which involve fraud, misrepresentation, bad
faith, or other willful misconduct by such Indemnified Person or which are in
material breach or violation by such Indemnified Person of this Agreement, in
each case as determined by a court of competent jurisdiction. No Indemnified
Person shall be liable to the Company or any other Member for actions taken in
good faith. The Company may indemnify other Persons of the Company. The duty of
the Company to indemnify the Indemnified Persons under this SECTION 3.3 shall be
limited to the assets of the Company, and no recourse shall be available against
any Member for satisfaction of such indemnification obligations of the Company.


                                   ARTICLE IV.

                           BOOKS; ELECTIONS; BUDGETS; FISCAL YEAR

                  Section 4.1. ADMINISTRATIVE SERVICES, BOOKS, RECORDS AND
REPORTS. The Managing Member shall cause to be performed all general and
administrative services on behalf of the Company in order to assure that
complete and accurate books and records of the Company are maintained at the
Company's principal place of business showing the names, addresses and number of
Units of each of the Members, all receipts and expenditures, assets and
liabilities, profits and losses, and all other records necessary for recording
the Company's business and affairs, including a capital account for each Member
(a "CAPITAL ACCOUNT"). Each Member's Capital Account shall be increased by:

                                    (i) the amount of any money contributed by
                  the Member to the Company;

                                    (ii) the fair market value of any property
                  contributed by the Member to the Company;

                                    (iii) the amount of Net Profits allocated to
                  the Member; and

                                    (iv) the amount of any Company liabilities
                  assumed by such Member (or taken subject to) if property is
                  distributed to the Member by the Company;

and shall be decreased by:

                                    (v) the amount of any money distributed to
                  the Member by the Company;

in the current and all preceding taxable years of the Company, equals the
product of (A) the highest combined federal, state and local marginal income tax
rate hypothetically applicable to any Member and (B) the excess, if any, of (i)

                  (b) The death, retirement, resignation, expulsion, bankruptcy
or dissolution of any Member or the occurrence of any other event that

                  (a) Upon a winding up of the Company, the Managing Member
shall be the liquidating Member (the "Liquidating Member") and shall proceed to
wind up the affairs of the Company, liquidate the remaining property and assets
of the Company and wind-up and terminate the business of the Company. The
Liquidating Member shall cause a full accounting of the assets and liabilities
of the Company to be taken and shall cause the assets to be liquidated and the
business to be wound up as promptly as possible by either or both of the
following methods: (1) selling the Company assets and distributing the net
proceeds therefrom (after the payment of Company liabilities) to each Member in
satisfaction of its Capital Account; or (2) distributing the Company assets to
the Members in kind and 

                                       18
<PAGE>   78


debiting the Capital Account of each Member with the fair market value of such
assets, each Member accepting an undivided interest in the partnership assets
(subject to their liabilities) in proportion to and to the extent of each
Member's positive Capital Account balance after allocating and crediting to the
Capital Accounts the unrealized gain or loss to the Members as if such gain or
loss had been recognized and allocated pursuant to SECTION 2.4.

                  (b) If the Company shall employ method (1) as set forth in
SECTION 7.2(A) in whole or part as a means of liquidation, then the proceeds of
such liquidation shall be applied in the following order of priority: (i) first,
to the expenses of such liquidation; (ii) second, to the debts and liabilities
of the Company to third parties, if any, in the order of priority provided by
law; (iii) third, a reasonable reserve shall be set up to provide for any
contingent or unforeseen liabilities or obligations of the Company to third
parties (to be held and disbursed, at the discretion of the Liquidating Member,
by an escrow agent selected by the Liquidating Member) and at the expiration of
such period as the Liquidating Member may deem advisable, the balance remaining
in such reserve shall be distributed as provided herein; (iv) fourth, to debts
of the Company to the Members or their Affiliates and any fees and
reimbursements payable under this Agreement; and (v) fifth, to the Members in
proportion to their respective positive Capital Account balances determined
after all allocations of Net Profit and Net Loss have been made.

                  (c) In connection with the liquidation of the Company, the
Members severally, jointly, or in any combination upon which they may agree,
shall have the first opportunity to make bids or tenders for all or any portion
of the assets of the Company, and such assets shall not be sold to an outsider
except only for a price higher than the highest and best bid of a single Member,
the Members jointly, or a combination of Members. Any bid made by a Member or
Members for all or any portion of the assets shall be made, if at all, within
thirty (30) days after the Liquidating Member or any other Member shall have
requested such bids. A copy of each bid shall be delivered by the Liquidating
Member to each Member. Unless otherwise agreed by all Members, no Member shall
be entitled to raise its bid after submission thereof, whether in response to a
bid received by the Company from any other Member or third party, or otherwise.

Agreement shall be construed as creating a partnership, joint venture, agency,

shall not be construed to be a waiver of such provision or the right of such
party thereafter to enforce such provision or any other provision of this
Agreement.

                  Section 10. SEVERABILITY. The illegality, invalidity or
unenforceability of any part of this Agreement shall not affect the legality,
validity or enforceability of the remainder of this Agreement. If any part of

6.  REGISTRATION AND ENFORCEMENT.

         6.1 REGISTRATION. Registration and any other form of protection for the
Trademarks shall only be obtained by Licensor in its name and at its expense. In
those jurisdictions where registration of a user of trademarks or registration
of trademark licenses is required by law, Licensor and Licensee shall make a

jurisdiction, for the registration of Licensee as a registered user of the
Trademarks or for the registration of this Agreement, as required. Licensee
shall furnish Licensor with all reasonably requested information (including
specimens and samples illustrative of the manner of use of the Trademarks) and

Licensor) to assist Licensor in obtaining and maintaining such trademark
protection and registrations.

of the Trademarks by third parties. Licensor shall have the sole discretion to
take action against such infringers or misusers or suspected infringers or
misusers, and any and all recoveries resulting from such actions initiated by
Licensor shall be retained by Licensor, except to the extent Licensee suffers
actual damages, in which event Licensee will be entitled to a portion of such
recovery equal to its percentage damage after deducting from the total amount of

shall not take any action with respect to any third party in an attempt to
enforce any rights regarding the Trademarks without the prior written approval

without the posting of bond or other security except as required by law. Such
remedy shall not be deemed to be the exclusive remedy for any such breach but
shall be in addition to all other remedies available at law or in equity.

its affiliates or any third party for any direct damages or for any special,
consequential, exemplary or incidental damages (including lost or anticipated
revenues or profits relating to the same), arising from any claim relating to
this Agreement or the Trademarks, whether such claim is based on warranty,
contract, tort (including negligence or strict liability) or otherwise, even if
an authorized representative of Licensor is advised of the possibility or
likelihood of same, unless Licensor is in breach of this Agreement.

         8.3 INDEMNIFICATION. Licensee agrees to indemnify and hold harmless
Licensor, its affiliates, and its and their stockholders, directors, officer,
employees, agents and assignees harmless and shall pay all losses, damages,
fees, expenses or costs (including reasonable attorneys' fees) incurred by them
based upon any claim, demand, suit or proceeding alleging that Licensee's
actions except as specifically permitted under this Agreement violate any rights
of any third party or alleging any breach by Licensee of any of its obligations
herein.

                  Licensor shall promptly notify Licensee of any such claim,
demand, suit or proceeding, and Licensee, upon written request by Licensor,
shall promptly defend and continue the defense of such claim, demand, suit or
proceeding at Licensee's expense. If Licensee fails to undertake and continue
such defense, Licensor shall have the right (but not the obligation) to make and
continue such defense as it considers appropriate, and the expenses and costs
thereof, including but not limited to reasonable attorneys' fees, out-of-pocket
costs and the costs of an appeal and bond thereof, together with the amounts of
any judgment rendered against Licensor shall be paid by Licensee upon demand.

                  Nothing herein shall prevent Licensor from defending, if it so
desires in its own discretion, any such claim, demand, suit or proceeding at its
own expense through its own counsel, notwithstanding that the defense thereof
may have been undertaken by Licensee.

                                    an independent contractor, Consultant is

                                    fees paid to Consultant.

Term. Consultant specifically acknowledges that: (i) the Confidential
Information, whether reduced to writing, maintained on any form of electronic

put forth by the Company to maintain the secrecy of such information; (iii) such
information is and will remain the sole property of the Company; and (iv) any

agrees that any Confidential Information gained by Consultant during his
association with the Company has been developed by the Company through
substantial expenditures of time and money and constitutes valuable and unique
property of the Company. Consultant further understands and agrees that the
foregoing makes it necessary for the protection of the Meckler Business and the
Company's Business that Consultant not compete with the Company during the term
of the Agreement, as further provided in the following sections.

         7. NONCOMPETITION DURING TERM. For three years from the Effective Date,

of the Company (other than employees, representatives, agents or consultants of
iWorld) to terminate his, her or its employment, representation or other
association with the Company.

         9. NONCOMPETITION - DIRECT OR INDIRECT. Consultant will be in violation
of SECTIONS 7, 8 and 10 if he engages in any or all of the activities set forth
in those sections directly as an individual on his own account, or indirectly
for any other Person and whether as partner, joint venturer, employee, agent,
salesperson, consultant, officer or director of any Person or as an equity
holder of any Person in which Consultant or Consultant's spouse, child or parent

prior written consent of the Company.

         13.      TERM AND TERMINATION.

                  (a) TERM. Unless earlier terminated pursuant to SECTION 15(b),

                  (b) BREACH. In the event that Consultant breaches, or fails to
comply with, any of the provisions of this Agreement, the Company, upon 10 days
prior written notice to Consultant specifying the nature of the breach or
failure to comply, has the right to terminate this Agreement (i) if Consultant
fails to cure such breach or fails to comply, if curable, within 10 days after
the giving of such written notice or (ii) within 10 days after the giving of
such written notice to Consultant, if such breach or failure to comply cannot be
cured.

                  (c) RETURN OR DESTRUCTION. Upon termination of this Agreement,
Consultant shall return, in good condition, all property of the Company,
including, without limitation, all tangible embodiments of the Confidential
Information.

                  (d) SURVIVAL. The obligations of the Company and Consultant
set forth in this Agreement that by their terms extend beyond or survive the
termination of this Agreement will not be affected or diminished in any way by
the termination of this Agreement.

         14.      GENERAL.

                  (a) NO LICENSE. This Agreement may not be construed to grant
and does not grant to Consultant any right or license with respect to any
know-how, Confidential Information, trademarks or other proprietary right of the
Company (apart from the right to make necessary use of the same in rendering
Consulting Services under this Agreement).

                   (b) REMEDIES. Consultant acknowledges that his failure to
comply with SECTIONS 5 THROUGH 14 of this Agreement will irreparably harm the
Meckler Business and the Company's Business and that the Company will not have
an adequate remedy at law in the event of such non-compliance. Therefore,
Consultant acknowledges that the Company will be entitled to injunctive relief
or specific performance without the posting of bond or other security, except as
required by law, in addition to whatever other remedies it may have, at law or
in equity, in any court of competent jurisdiction against any acts of
non-compliance by Consultant under this Agreement.

                   (c) LACK OF AGENCY. Neither party will be responsible, either
directly or indirectly, for any liability of the other party. Neither party is
deemed an agent of the other party and no actions of either party will be
inferred to create an agency relationship by third parties. Consultant shall not
have the authority to bind or obligate the Company in any way and Consultant
does not represent that he has such authority.

                   (d) SEVERABILITY. Should any provisions of this Agreement be
held illegal, invalid or unenforceable by any court or regulatory agency of
competent jurisdiction, such provision is to be modified by such court or
regulatory agency in compliance with the law and, as modified, enforced. All
other terms and conditions of this Agreement will remain in full force and
effect and are to be construed in accordance with the modified provision as if
such illegal, invalid or unenforceable provision had not been contained in this
Agreement.

                   (f) NO WAIVER. None of the terms of this Agreement is deemed
waived or amended by either party unless such a waiver or amendment specifically
references this Agreement and is in writing signed by an authorized
representative of the party to be bound. Any such signed waiver is effective
only in the specific instance and for the specific purpose for which it was made

                  (g) ASSIGNMENT. This Agreement is binding upon and inures to

                                    EXHIBIT F

                            LIST OF CONSENTS REQUIRED

1.       Denver West Office Park Lease by and between Denver West Office
         Building no. 1 Venture LLP and Board Watch Magazine, Inc. dated as of
         June 6, 1998.

                  Section 15.1 of the lease requires written consent from the
                  landlord prior to any transfer of the lease by Board Watch
                  Magazine, Inc. The section provides that a merger of a tenant
                  with another corporation is considered a transfer. Therefore,
                  consent must be acquired from the landlord prior to the merger
                  in order to avoid defaulting under the lease.

2.       Lease Agreement by and between Fifty East Forty Second Company and
         Mecklermedia Corporation dated as of November 5, 1997.

                  Section 11 of the lease requires written consent from the
                  landlord prior to any assignment of the lease by Mecklermedia
                  Corporation. The section provides that the transfer of the
                  majority of stock of a corporate tenant is considered an
                  assignment. Therefore, consent must be acquired from the
                  landlord prior to the merger in order to avoid defaulting
                  under the lease.

3.       Lease Agreement by and between Flying Dutchman Management, Inc. and
         Mecklermedia, Corp. dated as of November 25, 1997.

                  Section 7 of the lease requires written consent from the
                  landlord prior to any assignment of the lease by Mecklermedia,
                  Corp. The section provides that the sale, issuance or transfer
                  of any voting capital stock of the tenant (if tenant is a
                  non-public corporation), which results in a change in the
                  voting control of tenant, is considered an assignment.

4.       Agreement by and between New York Convention Center Operating
         Corporation ("Licensor") and Mecklermedia Corporation ("Licensee")
         dated as of July 23, 1998 (not yet executed)

                  Section 26 of the agreement requires Licensee to obtain
                  approval from Licensor in order to assign the agreement. The
                  section provides that a transfer by operation of law or the
                  transfer of a fifty percent interest in Licensee is considered
                  an assignment. Therefore, consent must be acquired from
                  Licensor prior to the merger in order to avoid defaulting
                  under the agreement.

5.       Agreement between Los Angeles Convention Center ("LACC") and
         Mecklermedia Corporation (currently out for execution) for Internet
         World Spring 1999.

Stock"), of the Company, and holds stock options (the "Options") to acquire an
aggregate of 271,000 shares of Common Stock granted pursuant to the Company's
1993 Stock Option Plan and the Company's 1995 Stock Option Plan; and

                  WHEREAS, Parent, Purchaser and the Company have entered into
an Agreement and Plan of Merger, dated as of the date hereof (as amended from
time to time, the "Merger Agreement"), which provides, among other things, that,
upon the terms and subject to the conditions therein, Purchaser will merge (the
"Merger") with and into the Company and each issued and outstanding share of
Common Stock will be converted into the right to receive $29.00 in cash; and

                  WHEREAS, as a condition to the willingness of Parent and
Purchaser to enter into the Merger Agreement, Parent and Purchaser have
requested that the Stockholder agree, and in order to induce Parent and
Purchaser to enter into the Merger Agreement, the Stockholder has agreed, to
enter into this Agreement.

                  NOW, THEREFORE, in consideration of the foregoing premises and
the representations, warranties, covenants and agreements set forth herein, and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, and subject to the terms and conditions set forth herein,
the parties hereto hereby agree as follows:

                                    ARTICLE I

                  Section 1. CERTAIN DEFINITIONS. Capitalized terms used but not
otherwise defined herein have the meanings ascribed to such terms in the Merger
Agreement.

                  Section 2. REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDER.
The Stockholder represents and warrants to Parent and Purchaser, as of the date
hereof and as of the Closing Date, as follows:

                          (a)      The Stockholder is the beneficial owner 
(as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), which meaning will apply for all purposes of this
Agreement) of, and has good title to, all of the Shares, free and clear of any

charge or similar restriction or limitation (each, a "Lien") (including any
restriction on the right to vote, sell or otherwise dispose of the Shares),
except as set forth in this Agreement.

                  (b) Other than the Options and the Warrant, the Shares
constitute all of the securities (as defined in Section 3(10) of the Exchange
Act, which definition will apply for all purposes of this Agreement) of the
Company beneficially owned, directly or indirectly, by the Stockholder
(excluding any securities beneficially owned by any of his affiliates or
associates (as such terms are defined in Rule 12b-2 under the Exchange Act,
which definition will apply for all purposes of this Agreement) as to which he
does not have voting or investment power).

                  (c) Except for the Shares, the Options and the Warrant, the
Stockholder does not, directly or indirectly, beneficially own or have any
option, warrant or other right to acquire any securities of the Company that are
or may by their terms become entitled to vote or any securities that are
convertible or exchangeable into or exercisable for any securities of the
Company that are or may by their terms become entitled to vote, nor is the
Stockholder subject to any contract, commitment, arrangement, understanding or
relationship (whether or not legally enforceable), other than this Agreement,
that allows or obligates him to vote or acquire any securities of the Company.
The Stockholder holds exclusive power to vote the Shares and has not granted a
proxy to any other Person to vote the Shares, subject to the limitations set
forth in this Agreement.

                  (d) This Agreement has been duly executed and delivered by the
Stockholder and, assuming due authorization, execution and delivery of this
Agreement by Parent and Purchaser, is a valid and binding obligation of the
Stockholder enforceable against the Stockholder in accordance with its terms,
except that (i) the enforceability hereof may be subject to applicable
bankruptcy, insolvency or other similar laws, now or hereinafter in effect,
affecting creditors' rights generally, and (ii) the availability of the remedy
of specific performance or injunctive or other forms of equitable relief may be
subject to equitable defenses and would be subject to the discretion of the
court before which any proceeding therefor may be brought.

                  (e) Neither the execution and delivery of this Agreement nor
the performance by the Stockholder of his obligations hereunder will conflict
with, result in a violation or breach of, or constitute a default (or an event
that, with notice or lapse of time or both, would result in a default) or give
rise to any right of termination, amendment, cancellation, or acceleration or
result in the creation of any Lien on any Shares under, (i) any contract,
commitment, agreement, understanding, arrangement or restriction of any kind to
which Stockholder is a party or by which the Stockholder is bound or (ii) any
injunction, judgment, writ, decree, order or ruling applicable to the
Stockholder; except for conflicts, violations, breaches or defaults that would
not individually or in the aggregate be reasonably expected to prevent or
materially impair or delay the consummation by Stockholder of the transactions
contemplated hereby.

<PAGE>   6



                  (f) To the knowledge of the Stockholder, neither the execution
and delivery of this Agreement nor the performance by the Stockholder of his
obligations hereunder will violate any law, decree, statute, rule or regulation
applicable to the Stockholder or require any order, consent, authorization or
approval of, filing or registration with, or declaration or notice to, any
court, administrative agency or other governmental body or authority, other than
any required notices or filings pursuant to the Hart-Scott-Rodino Antitrust

            Section 6. ADJUSTMENTS.

                  (a) In the event (i) of any stock dividend, stock split,
recapitalization, reclassification, combination or exchange of shares of capital
stock or other securities of the Company on, of or affecting the Shares or the
like or any other action that would have the effect of changing the
Stockholder's ownership of the Company's capital stock or other securities or
(ii) the Stockholder becomes the beneficial owner of any additional shares of

Agreement will apply to the shares of capital stock held by the Stockholder
immediately following the effectiveness of the events described in clause (i) or
the Stockholder becoming the beneficial owner thereof, as described in clause
(ii), as though they were Shares hereunder.

                  (b) The Stockholder hereby agrees, while this Agreement is in
effect, to promptly notify Parent of the number of any new shares of the Common
Stock acquired by the Stockholder, if any, after the date hereof.

                                   ARTICLE III

            Section 7. TENDER OF SHARES. The Stockholder will validly
tender (or cause the record owner of such shares to validly tender) and sell
(and not withdraw) pursuant to and in accordance with the terms of the Offer not
later than the fifteenth business day after commencement of the Offer all of the
Shares. Upon the purchase of all the Shares by Purchaser pursuant to the Offer
in accordance with this Section 7, this Agreement will terminate. In the event,
notwithstanding the provisions of the first sentence of this Section 7, any
Shares are for any reason withdrawn from the Offer or are not purchased pursuant
to the Offer, such Shares will remain subject to the terms of this Agreement.
The Stockholder acknowledges that Purchaser's obligation to accept for payment
and pay for the Shares in the Offer is subject to all the terms and conditions
of the Offer.

            Section 8. VOTING AGREEMENT.  The Stockholder, by this Agreement, 
does hereby constitute and appoint Parent and Purchaser, or any nominee thereof,
with full power of substitution, during and for the term of this Agreement, as
his true and lawful attorney and proxy for and in his name, place and stead, to
vote all the Shares Stockholder beneficially owns at the time of such vote, at
any annual, special or adjourned meeting of the stockholders of the Company (and
this appointment will include the right to sign his name (as stockholder) to any
consent, certificate or other document relating to the Company that laws of the
State of Delaware may require or permit) (x) in favor of approval and adoption
of the Merger Agreement and approval of the Merger and the other transactions
contemplated thereby and (y) against (a) any Acquisition Transaction, (b) any
action or agreement that would result in a breach in any respect of any
covenant, agreement, representation or warranty of the Company under the Merger
Agreement and (c) the following actions (other than the Merger and the other
transactions contemplated by the Merger Agreement): (i) any extraordinary
corporate transaction, such as a

                                        6


<PAGE>   10



merger, consolidation or other business combination involving the Company or its
Subsidiaries; (ii) a sale, lease or transfer of a material amount of assets of
the Company or one of its Subsidiaries, or a reorganization, recapitalization,
dissolution or liquidation of the Company or its Subsidiaries; (iii) (A) any
change in a majority of the persons who constitute the board of directors of the
Company as of the date hereof; (B) any change in the present capitalization of
the Company or any amendment of the Company's certificate of incorporation or
bylaws, as amended to date; (C) any other material change in the Company's
corporate structure or business; or (D) any other action that, in the case of
each of the matters referred to in clauses (iii)(A), (B) and (C) is intended, or
could reasonably be expected, to impede, interfere with, delay, postpone, or
adversely affect the Merger and the other transactions contemplated by this
Agreement and the Merger Agreement. This proxy and power of attorney is a proxy
and power coupled with an interest, and the Stockholder declares that it is
irrevocable. The Stockholder hereby revokes all and any other proxies with
respect to the Shares that he may have heretofore made or granted. For Shares as
to which the Stockholder is the beneficial but not the record owner, the
Stockholder shall use his best efforts to cause any record owner of such Shares
to grant to Parent a proxy to the same effect as that contained herein.

            Section 9. NO SOLICITATION. The Stockholder will not, directly
or indirectly, through any agent, financial advisor, attorney, accountant or
other representative or otherwise, (i) solicit, initiate or encourage submission
of proposals or offers from any Person relating to, or that could reasonably be
expected to lead to, an Acquisition Transaction or (ii) participate in any
negotiations or discussions regarding, or furnish to any other Person any
information with respect to, or otherwise cooperate in any way with, or assist
or participate in, facilitate or encourage, any effort or attempt by any other
Person to do or seek an Acquisition Transaction. The Stockholder shall
immediately advise Parent in writing of the receipt of request for information
or any inquiries or proposals relating to an Acquisition Transaction.

                                   ARTICLE IV

            Section 10. GRANT OF OPTION. The Stockholder hereby grants
Parent an irrevocable option (the "Parent Option") to purchase for cash, in a
manner set forth below, any or all of the Shares beneficially owned by the
Stockholder at a price (the "Exercise Price") per Share equal to the Per Share
Amount. In the event of any stock dividends, stock splits, recapitalizations,
combinations, exchanges of shares or the like, the Per Share Amount will be
appropriately adjusted for the purpose of this Section 10.

            Section 11. EXERCISE OF OPTION.

                  (a) Subject to the conditions set forth in Section 13 hereof,
the Parent Option may be exercised by Parent, in whole or in part, at any time
or from time to time after the occurrence of any Trigger Event (as defined
below). The Company and the Stockholder shall notify Parent promptly in writing
of the occurrence of any Trigger Event, it being understood that

                                        7


<PAGE>   11



the giving of such notice by the Company or the Stockholder is not a condition
to the right of Parent to exercise the Option. In the event Parent wishes to
exercise the Option, Parent shall deliver to the Stockholder a written notice
(an "Exercise Notice") specifying the total number of Shares it wishes to
purchase. Each closing of a purchase of Shares (a "Closing") will occur at a
place, on a date and at a time designated by Parent in an Exercise Notice
delivered at least two business days prior to the date of the Closing.

                  (b) A "Trigger Event" means any one of the following: (a) the
Merger Agreement becomes terminable under circumstances that could entitle
Parent to termination fees under Section 8.2(b)(i)(B) or Section 8.2(b)(ii) of
the Merger Agreement (regardless of whether the Merger Agreement is actually
terminated and whether such fees are then actually payable), (b) the Offer is
consummated but, due to the failure of the Stockholder to validly tender and not
withdraw, the Purchaser has not accepted for payment or paid for all of the
Shares, (c) a tender or exchange offer for some or all of the shares of Company
Common Stock shall have been publicly proposed to be made or shall have been
made by another person, or (d) it shall have been publicly disclosed or Parent
or Purchaser shall have otherwise learned that (i) any person or "group" (as
defined in Section 13(d)(3) of the Exchange Act) (other than Parent or
Purchaser) shall have acquired or proposed to acquire beneficial ownership of
more than 25% of any class or series of capital stock of the Company (including
the Common Stock), through the acquisition of stock, the formation of a group or
otherwise, or shall have been granted any option, right or warrant, conditional
or otherwise, to acquire beneficial ownership of more than 25% of any class or
series of capital stock of the Company other than acquisitions for bona fide
arbitrage purposes only and other than as disclosed in a Schedule 13D or 13G on
file with the SEC on September 1, 1998, (ii) any such person or group which,
prior to September 1, 1998, had filed such a Schedule with the SEC shall have
acquired or proposed to acquire beneficial ownership of additional shares of any
class or series of capital stock of the Company, through the acquisition of
stock, the formation of a group or otherwise, constituting 5% or more of any
such class or series, or shall have been granted any option, right or warrant,
conditional or otherwise, to acquire beneficial ownership of additional shares
of any class or series of capital stock of the Company (including the Common
Stock) constituting 5% or more of any such class or series, (iii) any person
(other than Parent or Purchaser) shall have filed a Notification and Report Form
under the HSR Act, or made a public announcement reflecting an intent to acquire
the Company or any assets or securities of the Company; or (iv) any person or
group (other than Parent and Purchaser) shall have entered into or offered to
enter into a definitive agreement or an agreement in principle with respect to a
merger, consolidation or other business combination with the Company.

            Section 12. TERMINATION OF OPTION. The Parent Option will
terminate (a) if this Agreement terminates pursuant to Section 7 or (b) upon the
earliest of: (i) the Effective Time; (ii) termination of the Merger Agreement
other than upon or during the continuance of a Trigger Event; or (iii) 180 days
following any termination of the Merger Agreement upon or during the continuance
of a Trigger Event (or if, at the expiration of such 180 day period the Parent
Option cannot be exercised by reason of any applicable judgment, decree, order,
law or regulation, 10

                                        8


<PAGE>   12

business days after such impediment to exercise has been removed or has become
final and not subject to appeal). Upon the giving by Parent to the Stockholder
of the Exercise Notice and the tender of the aggregate Exercise Price, Parent
will be deemed to be the holder of record of the Shares transferrable upon such
exercise, notwithstanding that the stock transfer books of the Company are then
closed or that certificates representing such Shares have not been actually
delivered to Parent.

            Section 13. CONDITIONS TO CLOSING. The obligation of the
Stockholder to sell the Shares to Parent hereunder is subject to the conditions
that (i) all waiting periods, if any, under the HSR Act, applicable to the sale
of the Shares or the acquisition of the Shares by Parent hereunder have expired
or have been terminated; (ii) all consents, approvals, orders or authorizations
of, or registrations, declarations or filings with, any court, administrative
agency or other governmental body or authority, if any, required in connection
with sale of the Shares or the acquisition of the Shares by Parent hereunder
have been obtained or made; and (iii) no preliminary or permanent injunction or
other order by any court of competent jurisdiction prohibiting or otherwise
restraining such sale or acquisition is in effect.

            Section 14. CLOSING. At any Closing, (a) the Stockholder will
deliver to Parent or its designee a certificate or certificates in definitive
form representing the number of the Shares designated by Parent in its Exercise
Notice, such certificate to be registered in the name of Parent or its designee
and (b) Parent will deliver to the Stockholder the aggregate Exercise Price for
the Shares so designated and being purchased by wire transfer of immediately
available funds. The Stockholder will pay all expenses, and any and all United
States federal, state and local taxes and other charges that may be payable in
connection with the preparation, issue and delivery of stock certificates under
this Section 14 in the name of Parent or its designee.

            Section 15. REGISTRATION RIGHTS.

                  (a) (i) Following termination of the Merger Agreement, Parent
     may by written notice (the "Registration Notice") to the Company, which
     Registration Notice the Parent shall concurrently send to the Stockholder,
     request the Company to register under the Securities Act all or any part of
     the shares of Common Stock acquired under the Parent Option (the "Parent
     Owned Shares" and such Parent Owned Shares requested to be registered for
     sale, the "Registrable Securities") pursuant to a bona fide firm commitment
     underwritten public offering in which Parent and the underwriters shall
     effect as wide a distribution of such Registrable Securities as is
     reasonably practicable and shall use their best efforts to prevent any
     person (including any Group (as used in Rule l3d-5 under the Exchange Act))
     and its affiliates from purchasing through such offering shares
     representing more than 1% of the outstanding shares of Common Stock on a
     fully diluted basis (a "Permitted Offering"). The Registration Notice will
     include a certificate executed by Parent and its proposed managing
     underwriter, which underwriter will be an investment banking firm of
     nationally recognized standing (the "Manager"), stating that 

                                        9


<PAGE>   13

     (A) they have a good faith intention to commence promptly a
     Permitted Offering and (B) the Manager in good faith believes that, based
     on the then prevailing market conditions, it will be able to sell the
     Registrable Securities at a per share price equal to at least 80% of the
     then Fair Market Value of such shares.

                  (ii) Upon receipt of the Registration Notice, the Stockholder
     will have the option exercisable by written notice delivered to Parent and
     the Company within nine business days after receipt of the Registration
     Notice, irrevocably to agree to purchase for cash at a price (the
     "Stockholder Option Price") equal to the product of (i) the number of
     Registrable Securities to be so purchased by the Stockholder and (ii) the
     then Fair Market Value of such shares all or any part of the Registrable
     Securities proposed to be so sold .

                  (iii) Upon receipt of the Registration Notice, the Company
     (and/or any person designated by the Company) will have the option
     exercisable by written notice delivered to Parent within ten business days
     after the receipt of the Registration Notice, irrevocably to agree to
     purchase for cash at a price (the "Company Option Price" and, together with
     the Stockholder Option Price, the "Option Price") equal to the product of
     (i) the number of Registrable Securities to be so purchased by the Company
     and (ii) the then Fair Market Value of such shares all or any part of the
     Registrable Securities proposed to be so sold and not purchased by the
     Stockholder pursuant to clause (ii) above.

                  (iv) Any such purchase of Registrable Securities by the
     Stockholder or the Company (or its designee) hereunder will take place at a
     closing to be held at the principal executive offices of the Company or at
     the offices of its counsel at any reasonable date and time designated by
     the Stockholder, the Company and/or such designee in such notice within 20
     business days after delivery of such notice. Any payment for the shares to
     be purchased will be made by delivery at the time of such closing of the
     Option Price in immediately available funds. As used herein, "Fair Market
     Value" means the average of the daily closing sales price for such share
     during the ten trading days prior to the fifth trading day preceding the
     date such Fair Market Value is to be determined.

                  (b) If the Stockholder and the Company, collectively, do not
elect to exercise their respective options pursuant to Section 15(a) with
respect to all Registrable Securities, the Company shall use commercially
reasonable efforts to effect, as promptly as practicable, the registration under
the Securities Act of the unpurchased Registrable Securities proposed to be so
sold; provided, however, that (i) Parent will be entitled to no more than an
aggregate of two effective registration statements hereunder and (ii) the
Company will not be required to file any such registration statement during any
period of time (not to exceed 40 days after such request in the case of clause
(A) below or 90 days in the case of clauses (B) and (C) below) when (A) the
Company is in possession of material non-public information that it reasonably
believes would be detrimental to be disclosed at such time and, in the opinion
of 

                                      10


<PAGE>   14


outside counsel to the Company, such information would have to be disclosed if a
registration statement were filed at that time; (B) the Company is required
under the Securities Act to include audited financial statements for any period
in such registration statement and such financial statements are not yet
available for inclusion in such registration statement; or (C) the Company
determines, in its reasonable judgment, that such registration would interfere
with any proposed financing, acquisition or other material transaction involving
the Company or any of its affiliates. The Company shall use its reasonable best
efforts to cause any Registrable Securities registered pursuant to this Section
15 to be qualified for sale under the securities or Blue-Sky laws of such
jurisdictions and Parent may reasonably request and shall continue such
registration or qualification in effect in such jurisdiction; provided, however,
that the Company will not be required to qualify to do business in, or to
consent to general service of process in, any jurisdiction by reason of this
provision.

                  (c) The registration rights set forth in this Section 15 are
subject to the condition that Parent shall provide the Company with such
information with respect to Parent's Registrable Securities, the plans for the
distribution thereof, and such other information with respect to such holder as,
in the reasonable judgment of counsel for the Company, is necessary to enable
the Company to include in such registration statement all material facts
required to be disclosed with respect to a registration thereunder.

                  (d) A registration effected under this Section 15 will be
effected at the Company 's expense, except for underwriting discounts and
commissions and the fees and the expenses of counsel to Parent (which will be
paid by Parent), and the Company shall provide to the underwriters such
documentation (including certificates, opinions of counsel and "comfort" letters
from auditors) as are customary in connection with unwritten public offerings as
such underwriters may reasonably require. In connection with any such
registration, the parties agree (i) to indemnify each other and the underwriters
in the customary manner, (ii) to enter into an underwriting agreement in form
and substance customary for transactions of such type with the Manager and the
other underwriters participating in such offering and (iii) to take all further
actions that will be reasonably necessary to effect such registration and sale
(including, if the Manager deems it necessary, participating in road-show
presentations).

                  (e) The Company will be entitled to include (at its expense)
additional shares of Common Stock in a registration effected pursuant to this
Section 15 only if and to the extent the Manager determines that such inclusion
will not adversely affect the prospects for success of such offering.

                                    ARTICLE V

            Section 16. PROFIT SHARING WITH PARENT. If (a) the Parent
Option becomes exercisable pursuant to Section 11 hereof, (b) Parent has not
exercised the Parent Option for all the Shares, and (c) not later than thirteen
months from the date of termination of the Merger 

                                       11


<PAGE>   15


Agreement, (i) the Company consummates a merger, acquisition, consolidation,
recapitalization, liquidation, dissolution or similar transaction involving, or
any purchase of all or a substantial portion of the assets or equity securities
of, the Company (a "Business Combination"), (ii) Stockholder disposes of any or
all of his Shares to any person not an affiliate or an associate of Parent or
Purchaser or to the Company or any affiliate thereof in connection with a
Business Combination or (iii) Stockholder realizes cash proceeds in respect of
such Shares as a result of a distribution to the Stockholder by the Company
following the sale of a material amount of the Company's assets in connection
with a Business Combination (each, a "Subsequent Transaction"), in each case at
a per share price or with equivalent per share proceeds (including, in the case
of clause (iii), the remaining value of the Shares), as the case may be (the
"Subsequent Price"), with a value in excess of the Per Share Amount, then the
Stockholder will promptly pay to Parent an amount equal to one-half of the
product of (x) the excess of the Subsequent Price over the Per Share Amount and
(y) the greatest number of Shares beneficially owned by the Stockholder between
the date hereof and the time a Business Combination is consummated (assuming for
this purpose that the Parent Option has not been exercised for any Shares) less
the number of Shares, if any, acquired by Parent upon exercise of the Parent
Option. In the event of any stock dividends, stock splits, recapitalizations,
combinations, exchanges of shares or the like or any other action that would
have the effect of changing the Stockholder's ownership of the Company's capital
stock or other securities, the Per Share Amount will be appropriately adjusted
for the purpose of this Section 16.

            Section 17. PROFIT SHARING WITH STOCKHOLDER.

                  (a) If (x) Parent exercises the Parent Option and (y) on or
after the earliest date of such exercise and not later than thirteen months from
the date of termination of the Merger Agreement, (i) the Company consummates a
Business Combination, (ii) Parent disposes of any or all of the Parent Owned
Shares to any person not an affiliate or an associate of Parent or Purchaser or
to the Company or any affiliate thereof in connection with a Business
Combination or (iii) Parent realizes cash proceeds in respect of the Parent
Owned Shares as a result of a distribution to Parent by the Company following
the sale of a material amount of the Company's assets in connection with a
Business Combination (each, a "Third Party Subsequent Transaction"), in each
case at a per share price or with equivalent per share proceeds (including, in
the case of clause (iii), the remaining value of the Parent Owned Shares), as
the case may be (the "Third Party Subsequent Price"), with a value in excess of
$31.00 (the "Threshold Price"), then Parent will promptly pay to the Stockholder
an amount equal to one-half of the product of (x) the excess of the Third Party
Subsequent Price over the Threshold Price and (y) the number of Parent Owned
Shares held by Parent at the time a Business Combination is consummated less
one-half of any amounts subject to recovery by the Company pursuant to Section
16(b) of the Exchange Act. In the event of any stock dividends, stock splits,
recapitalizations, combinations, exchanges of shares or the like or any other
action that would have the effect of changing Parent's ownership of the
Company's capital stock or other securities, the Threshold Price will be
appropriately adjusted for the purpose of this Section 17(a).

                  (b) If (x) Parent exercises the Parent Option granted in
Section 10 and (y) on or after the earliest date of such exercise and not later
than thirteen months from the date of termination of the Merger Agreement,
Parent, Purchaser or any affiliate or associate of Parent or Purchaser
consummates a Business Combination involving the Company at a per share price or
with equivalent per share proceeds (the "Parent Subsequent Price") with a value
in excess of the Per Share Amount, then Parent will promptly pay to the
Stockholder an amount equal to the product of (x) the excess of the Parent
Subsequent Price over the Per Share Amount and (y) the number of Parent Owned
Shares. In the event of any stock dividends, stock splits, recapitalizations,
combinations, exchanges of shares or the like or any other action that would
have the effect of changing Parent's ownership of the Company's capital stock or
other securities, the Per Share Amount will be appropriately adjusted for the
purpose of this Section 17(b).

Mecklermedia
THE INTERNET MEDIA COMPANY
 
                                October 15, 1998
 
Dear Fellow Stockholders:
 
     We are pleased to inform you that on October 7, 1998, Mecklermedia
Corporation (the "Company") entered into an Agreement and Plan of Merger (the
"Merger Agreement") with Penton Media, Inc. ("Parent") and Internet World Media,
Inc., a wholly owned subsidiary of Parent ("Purchaser"), pursuant to which
Purchaser has commenced a tender offer (the "Offer") to purchase all of the
outstanding shares of the Company's common stock, par value $0.01 per share (the
"Shares"), for a cash price of $29.00 per Share. The Offer is conditioned upon,
among other things, there being validly tendered prior to the expiration of the
Offer and not properly withdrawn a number of Shares which, together with the
Shares to be acquired pursuant to the Tender, Voting and Option Agreement, as
defined below, represents at least a majority of the total number of outstanding
Shares on a fully diluted basis. The Offer is also subject to certain other
terms and conditions as set forth in the accompanying Offer to Purchase. The
Merger Agreement provides that following consummation of the Offer, Purchaser
will be merged (the "Merger") with and into the Company and those Shares that
are not acquired in the Offer will be converted into the right to receive $29.00
per Share in cash.
 
     THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE OFFER AND ADOPTED THE
MERGER AGREEMENT AND DETERMINED THAT THE TERMS OF THE OFFER, THE MERGER AND THE
IWORLD TRANSACTION (AS DEFINED IN THE ENCLOSED SCHEDULE 14D-9) ARE FAIR TO, AND
IN THE BEST INTERESTS OF, THE COMPANY AND ITS STOCKHOLDERS, AND UNANIMOUSLY
RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR
SHARES PURSUANT TO THE OFFER. In arriving at its recommendation, the Board of
Directors considered the factors described in the accompanying Schedule 14D-9,
including the opinion of the Company's financial advisor, Allen & Company
Incorporated ("Allen & Company"), to the effect that the consideration to be
received by the stockholders of the Company pursuant to the Offer and the Merger
is fair to the holders of Shares, options and warrants from a financial point of
view. A copy of Allen & Company's written opinion, which sets forth the
assumptions made, procedures followed and matters considered in, and the
limitation on, the review by Allen & Company in rendering its opinion is
attached to the Schedule 14D-9 as Schedule I.
 
     The accompanying Offer to Purchase sets forth all of the terms of the
Offer. Additionally, the enclosed Schedule 14D-9 sets forth additional
information regarding the Offer and the Merger relevant to making an informed
decision. We urge you to read these materials carefully and in their entirety.
 
                                          Very truly yours,
 
                                          /s/ Alan M. Meckler

                   BY PENTON MEDIA IN AN ALL CASH TENDER OFFER
                   -------------------------------------------


         Mecklermedia Corporation (NASDAQ: Meck) today announced that it has
entered into a definitive agreement to be acquired by Penton Media (NYSE: PME)
for $29.00 per share in an all cash tender offer. The boards of directors of
Penton Media and Mecklermedia have approved the transaction and Alan Meckler,
Chairman of the Board and Chief Executive Officer, has agreed to tender
approximately 30% of the shares he beneficially owns. Mr. Meckler has also
granted an option to Penton Media to purchase such shares.

         The tender offer will be made promptly, and will be subject to certain
terms and conditions, including a minimum tender of a majority of the fully
diluted shares. The offer will be conditioned on Penton funding its financing.
Penton has entered into commitments with affiliates of Donaldson, Lufkin &
Jenrette Securities Corporation to provide the financing necessary for the
acquisition. Any shares not purchased in the offer will be acquired for $29.00
in cash in a subsequent merger. It is anticipated that the transaction could be
completed as early as November 1998.

               MECKLERMEDIA CORPORATION IN ALL-CASH TENDER OFFER;
                 TRANSACTION ACCELERATES PENTON GROWTH STRATEGY

CLEVELAND, OH -- October 8, 1998 -- Penton Media, Inc. (NYSE: PME) today
announced it has entered into a definitive merger agreement to acquire
Mecklermedia Corporation (NASDAQ: MECK) for approximately $274 million. Penton
Media will soon commence a tender offer to acquire all outstanding shares of
Mecklermedia's common stock for $29 per share, which represents a premium of
43.7% over Mecklermedia's closing price yesterday of $20.19. The transaction is
subject to certain terms and conditions, including the valid tender of at least
a majority of the shares outstanding on a fully diluted basis, the financing
referred to below, and normal regulatory approvals. Any shares not purchased in
the tender will be acquired for the same price in cash in a second-step merger.

Alan Meckler, chairman and CEO of Mecklermedia, who controls approximately 30%
of the outstanding shares of Mecklermedia common stock, has entered into an
agreement with Penton in which he has agreed, among other things, to tender his
shares into the offer and to give Penton an option to purchase his shares in the
case of a third party offer for Mecklermedia. Both companies anticipate that the
tender offer will close in November 1998.

The Boards of Directors of Penton Media and Mecklermedia have each unanimously
approved the acquisition by the vote of all directors present.

Penton said the transaction will be financed primarily through additional
borrowings. Donaldson, Lufkin & Jenrette, which initiated the transaction, and
its affiliates have committed to provide the financing necessary for Penton to
consummate the tender offer and the merger, refinance existing Penton
indebtedness, and pay related expenses. DLJ has acted as Penton's financial
advisor in connection with the transaction and is acting as dealer manager for
the tender.

Chief Executive Officer
Penton Media Inc.
1100 Superior Avenue
Cleveland, OH  44144


Dear Mr. Kemp:

         You have requested information from Mecklermedia Corporation (the
"Company") in connection with your consideration of a possible transaction with
the Company (a "Possible Transaction"). As a condition to our furnishing such
information to you, we are requiring that you agree, as set forth below, to
treat confidentially such information and any other information that the
Company, its agents or its representatives (including attorneys and financial
advisors) furnishes to you or your directors, officers, employees, agents,
advisors, prospective bank or institutional lenders, affiliates or
representatives of your agents, advisors or prospective lenders (all of the
foregoing collectively referred to as "your Representatives") who need to know
such information for the purpose of evaluating a Possible Transaction (it being
understood that your Representatives shall be informed by you of the
confidential nature of such information and shall be directed by you, and shall
each expressly agree, to treat such information confidentially in accordance
with this Agreement), whether furnished before or after the date of this letter,
and all notes, analyses, compilations, studies or other documents, whether
prepared by you or others, which contain or otherwise reflect such information
(collectively, the "Evaluation Material").

         The term "Evaluation Material" does not include information which (i)
becomes generally available to the public other than as a result of a disclosure
by you or your Representatives, (ii) was available to you on a non-confidential
basis prior to its disclosure to you by the Company, its representatives or its
agents, or (iii) becomes available to you on a non-confidential basis from a
source other than the Company, its representatives or its agents, provided that
such source is not bound by a contractual, legal or fiduciary obligation with
the Company, its

representatives or its agents or otherwise prohibited from transmitting the
information to you or your Representatives by a contractual, legal or fiduciary
obligation with the Company, its representatives or its agents.

         It is understood that you may disclose any of the Evaluation Material
to those of your Representatives who require such material for the purpose of
evaluating a Possible Transaction, subject to the terms of this Agreement. You
agree that the Evaluation Material will be kept confidential by you and your
Representatives and, except with the specific prior written consent of the
Company or as expressly otherwise permitted by the terms hereof, will not be
disclosed by you or your Representatives. You further agree that you and your
Representatives will not use any of the Evaluation Material for any reason or
purpose other than to evaluate a Possible Transaction. You shall agree to be
responsible for any breach of this Agreement by any of your Representatives.

         Without the prior written consent of the other party to this Agreement,
neither you and your Representatives nor the Company and its Representatives
will disclose to any person (other than their respective Representatives) (1)
the fact that the Evaluation Material has been made available to you or that you
have inspected any portion of the Evaluation Material, (2) the fact that any
discussions or negotiations are taking place concerning a Possible Transaction,
or (3) any of the terms, conditions or other facts with respect to any Possible
Transaction, including the status thereof, unless and only to the extent that
such disclosure (after using best efforts to avoid such disclosure and after
advising and consulting with the other party to this Agreement about such
party's intention to make, and the proposed contents of, such disclosure) is,
based on the advice of counsel reasonably acceptable to the Company, required by
applicable United States securities laws or by the New York Stock Exchange, in
your case, or the Nasdaq Stock Market, in the case of the Company. The term
"person" as used in this letter shall be broadly interpreted to include without
limitation any corporation, company, partnership and individual.

         In the event that you or any of your Representatives are requested or
required (by oral questions, interrogatories, requests for information or
documents, subpoena, Civil Investigative Demand or similar process) to disclose
any of the Evaluation Material, it is agreed that you or such Representative, as
the case may be, will provide the Company with prompt notice of such request(s)
so that it may seek an appropriate protective order or other appropriate remedy
and/or waive your or such Representative's compliance with the provisions of
this Agreement. You agree to assist the Company in taking any such steps to
protect the confidentiality of the Evaluation Material. In the event that such
protective order or 

                                     -2-

other remedy is not obtained, or that the Company grants a waiver hereunder, you
or such Representative may furnish that portion (and only that portion) of the
Evaluation Material which, based on the advice of your counsel reasonably
acceptable to the Company, you are legally compelled to disclose and will
exercise your best efforts to obtain reliable assurance that confidential
treatment will be accorded any Evaluation Material so furnished.

         In addition, you hereby acknowledge that you are aware (and that your
Representatives who are apprised of this matter have been or will be advised)
that the United States securities laws restrict persons with material non-public
information about a company obtained directly or indirectly from that company
from purchasing or selling securities of such company, or from communicating
such information to any other person under circumstances in which it is
reasonably foreseeable that such person is likely to purchase or sell such
securities.

         In view of the fact that the Evaluation Material consists of
confidential and non-public information, you agree that for a period of three
years from the date of this letter agreement, neither you nor any of your
affiliates, alone or with others, will in any manner acquire, agree to acquire,
or make any proposal (or request permission to make any proposal) to acquire any
securities (or direct or indirect rights, warrants or options to acquire any
securities) or property of the Company (other than property transferred in the
ordinary course of the Company's business), unless such acquisition, agreement
or making of a proposal shall have been expressly first approved (or in the case
of a proposal, expressly first invited) by the Company's Board of Directors,
solicit proxies from shareholders of the Company or otherwise seek to influence
or control the management or policies of the Company or any of its affiliates or
participate with or assist (including by knowingly providing or arranging
financing for that purpose) any other person in doing any of the foregoing. You
hereby represent that neither you nor any of your officers, directors or
subsidiaries (whether wholly owned or otherwise) beneficially own any shares of
the Common Stock of the Company.

         Without the prior written consent of the Company, (1) neither you nor
those of your Representatives who are aware of the Evaluation Material and/or
the possibility of a Possible Transaction will initiate or cause to be initiated
(other than through Allen & Company) any communications with any employee or
representative of the Company concerning the Evaluation Material or any Possible
Transaction and (2) none of your directors, officers or employees who are aware
of the Evaluation Material and/or the possibility of a Possible Transaction
will, for the two-year period from the date of this letter Agreement, solicit or
cause to be solicited the employment or hire of any employee of the Company with
whom you or any of your Representatives have had or subsequently have any
contact, whether in person or 

                                     -3-

otherwise, during the course of your consideration of a Possible Transaction.

         You will promptly upon the written request of the Company deliver to
the Company all documents or other matter furnished by the Company to you or
your Representatives constituting Evaluation Material, together with all copies
thereof in the possession of you or your Representatives. In the event of such
request, all other documents or other matter constituting Evaluation Material
and any other written materials (whatever the form or storage medium) in the
possession of you or your Representatives will be destroyed, with any such
destruction confirmed by you in writing to the Company.

         Although you understand that the Company has endeavored to include in
the Evaluation Material information known to it which it believes to be relevant
for the purpose of your investigation, you further understand that neither the
Company nor its agents or its representatives makes any representation or
warranty as to the accuracy or completeness of the Evaluation Material. You
agree that neither the Company nor its agents or its representatives shall have
any liability to you or any of your Representatives resulting from the use of
the Evaluation Material by you or such Representatives. Only those
representations and warranties that may be made to you or your affiliates in a
definitive written agreement for a transaction, when, as and if executed and
subject to such limitations and restrictions as may be specified therein, shall
have any legal effect, and you agree that if you determine to engage in a
transaction such determination will be based solely on the terms of such written
agreement and on your own investigation, analysis and assessment of the business
to be acquired. Moreover, unless and until such a definitive written agreement
is entered into, none of the Company, its affiliates or you will be under any
legal obligation of any kind whatsoever with respect to such a transaction or
any Possible Transaction except for the matters specifically agreed to in this
Agreement. The agreements set forth in this Agreement may be modified or waived
only by a separate writing signed by the Company and you expressly so modifying
or waiving such agreements.

         You hereby agree to indemnify and hold harmless the Company from any
damage, loss, cost or liability (including legal fees and the cost of enforcing
this indemnity) arising out of or resulting from any unauthorized use or
disclosure by you or your Representatives of the Evaluation Material. You also
acknowledge that money damages would be both incalculable and an insufficient
remedy for any breach of this Agreement by you or your Representatives and that
any such breach would cause the Company irreparable harm. Accordingly, you also
agree that in the event of any breach or threatened breach of this Agreement,
the Company, in addition to any other remedies at law or in equity it 

                                     -4-

may have, shall be entitled, without the requirement of posting a bond or other
security, to equitable relief, including injunctive relief and specific
performance.

         You further understand and agree that (i) the Company and Allen &
Company shall be free to conduct the process for a Possible Transaction as they
in their sole discretion shall determine without notice to you, (ii) any
procedures relating to such Possible Transaction may be changed at any time
without notice to you or any other person and (iii) you shall not have any claim
whatsoever against the Company, Allen & Company and/or any of their respective
directors, officers, employees, stockholders, affiliates, agents or
representatives arising out of any Possible Transaction.

         It is understood and agreed that no failure or delay by the Company in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any right, power or privilege
hereunder.

         The invalidity or unenforceability of any provision of this Agreement
shall not affect the validity or enforceability of any other provisions of this
letter agreement, which shall remain in full force and effect.

         You agree and consent to personal jurisdiction and service and venue in
any federal or state court within the State of New York having subject matter
jurisdiction, for the purposes of any action, suit or proceeding arising out of
or relating to this Agreement. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York, without regard to the
conflicts of law principles thereof.

                                October 7, 1998
 
Members of the Board of Directors
Mecklermedia Corp.
20 Ketchum Street
Westport, Connecticut 06880
 
To the Board of Directors
 
     We are pleased to confirm in writing our presentation to a meeting of the
Board of Directors on Wednesday, October 6, 1998, of our opinion, as of this
date, as to (a) the fairness, from a financial point of view, of the
consideration to be received by the holders of the outstanding shares of Common
Stock, .01 par value per share (the "Common Stock"), and options and warrants to
purchase Company Common Stock of Mecklermedia Corp., a Delaware corporation (the
"Company"), and (b) the fairness, from a financial point of view, to the Company
of the terms of the Proposed Transactions referred to hereinafter.
 
     Pursuant to the proposed Agreement and Plan of Merger (the "Merger
Agreement"), to be entered into by and among the Company, Penton Media Inc., a
Delaware corporation, (the "Purchaser"), and a wholly-owned subsidiary of the
Purchaser (the "Merger Sub"), the Company will enter into a business combination
transaction effected by a cash tender offer made by Purchaser and Merger Sub for
Company Common Stock and options and warrants to purchase Company Common Stock,
to be followed by a merger of Merger Sub with and into the Company (the "Merger
Transaction"). In connection with the Merger Transaction, Purchaser at the
Effective Time will cause the organization of a limited liability company under
Delaware law ("Newco"), to which Purchaser is to contribute the Company's
internet business assets in consideration for Newco's issuance to Purchaser of
19.9% of Newco's equity

Page 2

interest. At the Effective Time, in consideration of the payment of $18
million, Newco is to issue 80.1% of its equity interest to Alan M. Meckler, the
Company's founder, principal stockholder and Chief Executive Officer, which
equity interest is subject to dilution pursuant to an option granted by Mr.
Meckler to Purchaser (the "Newco Transaction" and, collectively with the Merger
Transaction, the "Proposed Transactions"). In connection with the Proposed
Transactions, Mr. Meckler has granted Purchaser the option to purchase for cash
and without interest his Common Stock at the same price per share offered to
other Company stockholders in the Merger Transaction. Unless otherwise
specifically defined herein, all capitalized terms used herein shall have the 
meanings ascribed to such terms in the Merger Agreement.
 
     Pursuant to the terms, and subject to the conditions contained in, the
documentation relating to the Proposed Transactions, among other things, (i)
Purchaser will make a tender offer to purchase all shares of Company Common
Stock for a purchase price of $29 in cash, without interest, subject to certain
terms and conditions; (ii) Purchaser will offer to purchase Company issued
warrants and options to purchase Common Stock in cash without interest for a
price equal to the difference between $29 and the exercise price of such
warrants and options; and (iii) Mr. Meckler will acquire an 80.1% equity
interest in the Company's internet business assets held by Newco for an
aggregate purchase price of $18 million in cash (subject to dilution by
Purchaser's option to purchase from Mr. Meckler 10% of Newco), and the remaining
19.9% equity interest in Newco will be issued to Purchaser or one of its
affiliates. As part of the Proposed Transactions, Newco and Purchaser are to
enter into license and service agreements, and Mr. Meckler will enter into a
non-competition and consulting agreement with Purchaser.

     We understand that all approvals required for the consummation of the
Proposed Transactions have been or, prior to consummation of the Proposed
Transactions, will be obtained. We understand Purchaser has obtained financing
commitments subject to certain terms and conditions which commitments, when
funded and combined with the existing working capital of the Purchaser and the
Company, will be sufficient to timely meet Purchaser's obligations under the
Merger Agreement. We note the Proposed Transactions are conditioned on the
funding of such financing commitments.

 
     As you know Allen & Company Incorporated ("Allen") will receive a fee for
preparing and rendering this opinion pursuant to the engagement letter agreement
by and between the Company and Allen. We note that Allen beneficially owns
30,000 shares of the Company's Common Stock.
 
     In arriving at our opinion, we have among other things:
 
          (i) reviewed the terms and conditions of the Proposed Transactions,
     including the draft Merger Agreement and the draft agreements ancillary
     thereto, including the draft Newco Agreement between Newco and the
     Purchaser (none of which prior to the delivery of our opinion has been
     executed by the parties), as well as commitment letters summarizing certain
     of Purchaser's financing arrangements;

<PAGE>   4


Members of the Board of Directors
Mecklermedia Corp.

Page 4
 
          (ii) analyzed publicly available historical business and financial
     information relating to the Company and the Purchaser, as presented in
     documents filed with the Securities and Exchange Commission;
 
          (iii) reviewed certain financial, operating and budgetary data
     provided to us by the Company relating to its businesses;
 
          (iv) conducted discussions with certain members of the senior
     management of the Company with respect to the financial condition,
     business, operations, strategic objectives and prospects of the Company, as
     well as industry trends prevailing in the Company's business;
 
          (v) reviewed and analyzed public information, including certain stock
     market data and financial information relating to selected public companies
     in lines of business which we believe to be comparable to the Company's, as
     well as analysts' reports and estimates for the Company;
 
          (vi) reviewed the trading history of the Company's and the Purchaser's
     Common Stock, including their performance in comparison to market indices
     and to selected companies in comparable businesses;
 
          (vii) reviewed public financial and transaction information relating
     to business combinations we deemed to be comparable to the Proposed
     Transactions;
 

<PAGE>   5

Members of the Board of Directors
Mecklermedia Corp.

Page 5
 
          (viii) considered premiums and multiples paid in recent transactions
     we deemed comparable to the Merger Transaction;

          (ix) conducted such other financial analyses and investigations as we
     deemed necessary or appropriate for the purposes of the opinion expressed
     herein.
 
     In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of the financial and other information respecting the Company and
the Purchaser and any other information provided to us, and we have not assumed
any responsibility for any independent verification of such information or any
independent valuation or appraisal of any of the assets of the Company. With
respect to the business plans referred to above, we have assumed that they have
been reasonably prepared on a basis reflecting the best currently available
information and the good faith estimates and judgments of the management of the
Company as to the future financial performance of the Company's business.
 
     In addition to our review and analysis of the specific information set
forth above, our opinion herein reflects and gives effect to our knowledge of
the industry and our assessment of general economic, monetary and market
conditions existing as of the date hereof as they may affect the business and
prospects of the Company.
 
     We have prepared this opinion at the request and for the benefit of the
Board of Directors of the Company, and consent to its inclusion in filings the
Company may be required to make with the Securities and Exchange Commission. The
opinion rendered herein does not constitute a recommendation that the Company
pursue the Proposed Transactions or that any stockholder of the Company vote to
approve the Proposed Transactions.

     Based on and subject to the foregoing, we are of the opinion that, as of
this date, (a) the consideration to be received pursuant to the Merger
Transaction by the holders of the Company's Common Stock and options and
warrants to purchase Common Stock is fair to such holders from a financial point
of view, and (b) the terms of the Proposed Transactions are fair to the Company
from a financial point of view.
