AGREEMENT AND PLAN OF MERGER (this "Agreement") dated as of October 25, 2001, among NETRATINGS, INC., a Delaware corporation ("Parent"), SONOMA ACQUISITION CORP., LLC., a Delaware limited liability company of which Parent is the sole member ("Sub"), and JUPITER MEDIA METRIX, INC., a Delaware corporation (the "Company").

WHEREAS the respective Boards of Directors of Parent, Sub and the Company have approved, and the Boards of Directors of Sub and the Company have declared advisable, this Agreement and the merger of Sub with and into the Company (the "Merger"), upon the terms and subject to the conditions set forth in this Agreement, whereby each issued and outstanding share of common stock, par value $0.01 per share, of the Company (the "Company Common Stock"), other than shares owned by Parent, Sub or the Company, or any wholly owned subsidiary of Parent, Sub or the Company, will be converted into, at the option of the holder thereof (upon the terms and subject to the limitations set forth herein), either (i) the right to receive shares, par value $.01 per share, of Parent (the "Parent Shares"), or (ii) the right to receive cash;

WHEREAS simultaneously with the execution and delivery of this Agreement and as a condition and inducement to the willingness of Parent and Sub to enter into this Agreement, Parent and certain officers and directors of the Company (collectively, the "Signatory Stockholders") are entering into an agreement (the "Stockholder Agreement") pursuant to which the Signatory Stockholders will severally and not jointly agree to vote to adopt and approve this Agreement and to take certain other actions in furtherance of the Merger upon the terms and subject to the conditions set forth in the Stockholder Agreement; and

ARTICLE I

The Merger

SECTION 1.01. The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the Delaware General Corporation Law (the "DGCL") and the Delaware Limited Liability Company Act (the "LLC Act"), Sub shall be merged with and into the Company at the Effective Time (as defined in Section 1.03). At the Effective Time, the separate corporate existence of Sub shall cease and the Company shall continue as the surviving corporation (the "Surviving Corporation") and shall succeed to and assume all the rights and obligations of Sub in accordance with the DGCL and the LLC Act.

SECTION 1.02. Closing. The closing of the Merger (the "Closing") shall take place at 10:00 a.m., Pacific Standard Time, on the second business day after satisfaction or (to the extent permitted by applicable law) waiver of the conditions set forth in Article VII (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions), at the offices of ▇▇▇▇ ▇▇▇▇ ▇▇▇▇ & Freidenrich LLP, ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇, or at such other place, time and date as shall be agreed to in writing by Parent and the Company. The date on which the Closing occurs is referred to in this Agreement as the "Closing Date."

SECTION 1.03. Effective Time. Upon the terms and subject to the conditions set forth in this Agreement, as soon as practicable following the Closing, the Company shall prepare and file with the Secretary of State of the State of Delaware, a certificate of merger or other appropriate documents (in

any such case, the "Certificate of Merger") executed in accordance with the relevant provisions of the DGCL and the LLC Act. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware, or at such subsequent date or time as Parent and the Company shall agree and specify in the Certificate of Merger (the time the Merger becomes effective being referred to as the "Effective Time").

SECTION 1.04. Effects of the Merger. The Merger shall have the effects set forth in the applicable provisions of the DGCL and the LLC Act.

SECTION 1.07. Officers. The officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

ARTICLE II

Effect of the Merger on the Capital Stock of the
Constituent Corporations; Exchange of Certificates

SECTION 2.01. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Company Common Stock or the sole member of Sub:

(a) Capital Stock of Sub. The sole membership interest of Sub held by Parent shall be converted into one fully paid and nonassessable share of common stock of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. Each share of Company Common Stock that is owned by the Company, as treasury stock, Parent or Sub, or any wholly-owned subsidiary of the Company, Parent or Sub, immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist, and no consideration shall be delivered or deliverable in exchange therefor.

(c) Conversion of Company Common Stock. Except as otherwise provided in Section 2.05 and subject to Sections 2.01(d), 2.01(e) and 2.03(e), each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 2.01(b)) shall be converted into the right to receive, at the election of the holder thereof, one of the following (as adjusted pursuant to Section 2.05, the "Merger Consideration"):

(i) for each such share of Company Common Stock with respect to which an election to receive Parent Shares has been effectively made, and not revoked or lost, pursuant to Section 2.04 (a "Share Election") and for each share of Company Common Stock with respect to which a Share Election is deemed to have been made pursuant to Section 2.04(d), the right to receive consideration (the "Share Consideration") equal to .1490 fully paid and nonassessable Parent Shares (the "Exchange Ratio"); and

(ii) for each such share of Company Common Stock with respect to which an election to receive cash has been effectively made, and not revoked or lost, pursuant to Section 2.04 (a "Cash Election") and for each share of Company Common Stock with respect to which a Cash Election is deemed to have been made pursuant to Section 2.04(d), the right to receive $1.95 in cash (the "Cash Consideration").

At the Effective Time, all such shares of Company Common Stock converted as set forth above shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate or certificates that immediately prior to the Effective Time represented any such shares of Company Common Stock (the "Certificates") shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, certain dividends or other distributions in accordance with Section 2.03(c) and cash in lieu of any fractional share in accordance with Section 2.03(e) upon the surrender of such Certificate in accordance with Section 2.03(b), without interest.

(d) Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares ("Appraisal Shares") of Company Common Stock that are outstanding immediately prior to the Effective Time and that are held by any person who is entitled to demand and properly demands appraisal of such Appraisal Shares pursuant to, and who complies in all respects with, Section 262 of the DGCL ("Section 262") shall not be converted into Merger Consideration as provided in Section 2.01(c), but rather the holders of Appraisal Shares shall be entitled to payment of the fair market value of such Appraisal Shares in accordance with Section 262; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262, then the right of such holder to be paid the fair value of such holder's Appraisal Shares shall cease and such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive, the Merger Consideration as provided in Section 2.01(c). The Company shall serve prompt notice to Parent of any demands received by the Company for appraisal of any shares of Company Common Stock, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

(e) Adjustments to Merger Consideration. The Exchange Ratio and the Cash Consideration shall be subject to reduction if (i) the "JV Termination Expenses" shall exceed the "Permitted Amount" (as such terms are defined in Section 6.17) (such excess amount being referred to herein as the "Excess Expenses"), and/or (ii) the Company shall borrow funds from Parent pursuant to the provisions of the "Loan and Security Agreement" described in Section 6.18. Each of the Exchange Ratio and the Cash Consideration shall be adjusted as described, and in the amounts determined, as follows:

(i) The (A) Excess Expenses, if any, shall be added to (B) the aggregate principal amount of funds borrowed by the Company from Parent, plus any interest accrued thereon through the Adjustment Measurement Date (as such term is defined below) and any "Parent Loan Expenses" (but only to the extent unpaid at the Adjustment Measurement Date) as such term is described in the Loan and Security Agreement (but only to the extent that such aggregate amount shall exceed the lesser of (x) the JV Termination Expenses actually paid prior to the Adjustment Measurement Date, as such term is defined below, and (y) the Permitted Amount) through the third day immediately preceding the mailing of the Proxy Statement (as such term is defined in Section 3.04(b), with such date being referred to as the "Adjustment Measurement Date") to the Company's stockholders. The sum of the amounts in clauses (A) and (B) is defined as the "Aggregate Consideration Adjustment Amount".

(ii) The Cash Consideration shall be reduced by the "Per Share Cash Adjustment Amount." The Per Share Cash Consideration Adjustment Amount shall be equal to the quotient determined by dividing (A) the Aggregate Consideration Adjustment Amount by (B) the Company Common Stock Capitalization Number, rounding up to the nearest whole cent. For purposes of this calculation, the Company Common Stock Capitalization Number shall mean the number of shares of Company Common Stock outstanding on the Adjustment Measurement Date as certified to Parent by the Company's transfer agent.

(iii) The Exchange Ratio shall be recalculated and shall be equal to the amount determined as the product of (A) .1490 multiplied by (B) the quotient determined by dividing (x) the Cash Consideration as reduced pursuant to clause (ii) above by (y) $1.95.

SECTION 2.02. Anti-Dilution Provisions. In the event Parent changes (or establishes a record date for changing) the number of Parent Shares issued and outstanding prior to the Effective Time as a result of a stock split, stock dividend, recapitalization, subdivision, reclassification, combination, exchange of shares or similar transaction with respect to the outstanding Parent Shares and the record date therefor shall be prior to the Effective Time, the Exchange Ratio shall be proportionately adjusted to reflect such stock split, stock dividend, recapitalization, subdivision, reclassification, combination, exchange of shares or similar transaction.

SECTION 2.03. Exchange of Certificates.

(a) Exchange Agent. As of the Effective Time, Parent shall provide, or cause the Surviving Corporation to deposit with such bank or trust company as may be designated by Parent and reasonably acceptable to the Company (the "Exchange Agent"), for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Article II, through the Exchange Agent, the Parent Shares issuable pursuant to Section 2.01 in exchange for outstanding shares of Company Common Stock, and Parent shall take all steps necessary to enable and cause the Surviving Corporation to provide to the Exchange Agent, on a timely basis, as and when needed after the Effective Time, cash necessary to pay for the shares of Company Common Stock converted into the right to receive cash pursuant to Section 2.01 (such Parent Shares and cash, together with any dividends or other distributions with respect thereto in accordance with Section 2.03(c) and any cash in lieu of any fractional Parent Shares in accordance with Section 2.03(e), being hereinafter referred to as the "Exchange Fund"). At the time of such deposit, Parent shall irrevocably instruct the Exchange Agent to deliver the Exchange Fund to the Company's stockholders after the Effective Time in accordance with the procedures set forth in this Section 2.03, subject to Sections 2.03(f) and 2.03(g).

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a Certificate whose shares were converted into the right to receive the applicable Merger Consideration pursuant to Section 2.01, (i) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in customary form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in surrendering the Certificates in exchange for the applicable Merger Consideration with respect thereto. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor that number of whole Parent Shares (together with cash in lieu of any fractional Parent Shares in accordance with Section 2.03(e)), if any, and the amount of cash, if any, that the aggregate number of shares of Company Common Stock previously represented by such Certificate shall have been converted pursuant to Section 2.01, together with certain dividends or other distributions in accordance with Section 2.03(c), and the Certificate so surrendered shall forthwith be canceled. In the event of a

transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, a certificate evidencing the proper number of Parent Shares may be issued and/or the proper amount of cash may be paid, as appropriate, in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such issuance shall pay any transfer or other taxes required by reason of the issuance of Parent Shares to a person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.03(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration that the holder thereof has the right to receive pursuant to the provisions of this Article II, certain dividends or other distributions in accordance with Section 2.03(c) and cash in lieu of any fractional Parent Shares in accordance with Section 2.03(e). No interest shall be paid or will accrue on any cash payable upon surrender of any Certificate.

(c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made with respect to Parent Shares with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to Parent Shares represented thereby, if any, and all such dividends and other distributions shall be paid by Parent to the Exchange Agent and shall be included in the Exchange Fund, until the surrender of such Certificate in accordance with this Article II. Subject to the effect of applicable escheat or similar laws, following surrender of any such Certificate there shall be paid to the holder of whole Parent Shares issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole Parent Shares and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole Parent Shares.

(d) No Further Ownership Rights in Company Common Stock. All certificates evidencing Parent Shares issued and cash paid upon the surrender for exchange of Certificates in accordance with the terms of this Article II (including any dividends or other distributions paid pursuant to Section 2.03(c) and any cash in lieu of any fractional Parent Shares paid pursuant to Section 2.03(e)) shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to the shares of Company Common Stock formerly represented by such Certificates, subject, however, to the Surviving Corporation's obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been declared or made by the Company prior to the date of this Agreement with respect to such shares of Company Common Stock which remain unpaid at the Effective Time. At the close of business on the day on which the Effective Time occurs, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for transfer or any other reason, they shall be canceled and exchanged as provided in this Article II.

(e) No Fractional Shares.

(i) No certificates or scrip representing, or receipts evidencing, fractional Parent Shares shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to Parent Shares shall relate to such fractional shares interests and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a stockholder of Parent.

(ii) Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a Parent Share (after taking into account all such shares held by such holder) shall receive, in lieu thereof, cash (without interest) in an amount, less the amount of any withholding taxes that may be required thereon, equal to such fractional part of a Parent Share (rounded to the fourth decimal place) multiplied by the Cash Consideration.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of the Certificates for six months after the Effective Time shall be delivered to Parent, upon demand, and any holders of the Certificates who have not theretofore complied with this Article II shall thereafter look only to Parent for, and, subject to Section 2.03(g), Parent shall remain liable for payment of their claim for the Merger Consideration, certain dividends and other distributions in accordance with Section 2.03(c) and any cash in lieu of any fractional Parent Shares in accordance with Section 2.03(e).

(g) No Liability. None of Parent, Sub, the Company or the Exchange Agent shall be liable to any person in respect of any certificates evidencing Parent Shares (or any dividends or distributions with respect thereto) or cash from the Exchange Fund, in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to three years after the Effective Time (or immediately prior to such earlier date on which any amounts payable pursuant to this Article II would otherwise escheat to or become the property of any Governmental Entity), any such amounts shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(h) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Parent, on a daily basis; provided that no such investment or loss thereon shall affect the amounts payable to the Company's stockholders pursuant to this Article II. Any interest and other income resulting from such investments shall be the property of, and shall be paid to, Parent, and Parent shall be responsible for paying all taxes with respect to such interest and other income.

(i) Lost Certificates. If any Certificate shall have 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 and, if required by Parent, the posting by such person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto, certain dividends and other distributions in accordance with Section 2.03(c) and any cash in lieu of any fractional Parent Shares in accordance with Section 2.03(e).

(j) Withholding Rights. Parent, Sub or the Exchange Agent shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as Parent, Sub or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent, Sub or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by Parent, Sub or the Exchange Agent.

SECTION 2.04. Share Elections.

(a) Each person who, on or prior to the Election Date referred to in Section 2.04(b), is a record holder of shares of Company Common Stock shall be entitled, with respect to all or any

portion of such shares, to make an unconditional Share Election or an unconditional Cash Election, in each case specifying that number of shares of Company Common Stock such holder desires to have converted into the Share Consideration and that number of shares of Company Common Stock such holder desires to have converted into the Cash Consideration, as applicable, on or prior to such Election Date, on the basis hereinafter set forth.

(b) Parent shall prepare a form of election, which form shall be subject to the reasonable approval of the Company (the "Form of Election") and shall be mailed with the Proxy Statement to the record holders of Company Common Stock as of the record date for the Stockholders Meeting, which Form of Election shall be used by each record holder of shares of Company Common Stock who wishes to elect to receive the Share Consideration or the Cash Consideration, as applicable, for any or all shares of Company Common Stock held by such holder. The Company shall use all reasonable efforts to make the Form of Election and the Proxy Statement available to all persons who become record holders of Company Common Stock during the period between such record date and the Election Date. Any such holder's (and such authorized representative's) election to receive the Share Consideration or the Cash Consideration, as applicable, shall have been properly made only if the Exchange Agent shall have received a Form of Election, properly completed and signed, at its designated office, by 5:00 p.m., New York City time, on the business day immediately preceding the date of the Stockholders Meeting (the "Election Date").

(c) Any Form of Election may be revoked, by the stockholder who submitted such Form of Election to the Exchange Agent, only by written notice received by the Exchange Agent (i) prior to 5:00 p.m., New York City time, on the Election Date or (ii) after such time, if (and only to the extent that) the Exchange Agent is legally required to permit revocations and only if the Effective Time shall not have occurred prior to such date. In addition, all Forms of Election shall automatically be revoked if the Exchange Agent is notified in writing by Parent and the Company that the Merger has been abandoned. If a Form of Election is revoked, the Certificate or Certificates (or guarantees of delivery, as appropriate) for the shares of Company Common Stock to which such Form of Election relates shall be promptly returned to the stockholder that submitted the same to the Exchange Agent.

(d) The determination of the Exchange Agent in its sole discretion shall be binding as to whether or not elections to receive the Share Consideration or the Cash Consideration have been properly made or revoked pursuant to this Section 2.04 with respect to shares of Company Common Stock and when elections and revocations were received by it. If no Form of Election is received with respect to shares of Company Common Stock, or if the Exchange Agent determines that any election to receive the Merger Consideration was not properly made with respect to shares of Company Common Stock, the holder of such shares shall be treated by the Exchange Agent as having submitted a (i) a Share Election with respect to 50% of the shares held by such holder and (ii) Cash Election with respect to 50% of the shares held by such holder and, subject to Section 2.05, such shares shall be converted at the Effective Time into the right to receive the appropriate amount of Share Consideration and Cash Consideration. The Exchange Agent shall also make all computations as to the proration contemplated by Section 2.05, and absent manifest error any such computation shall be conclusive and binding on the holders of shares of Company Common Stock. The Exchange Agent may, with the mutual agreement of Parent and the Company, make such rules as are consistent with this Section 2.04 for the implementation of the elections provided for herein as shall be necessary or desirable fully to effect such elections and the provisions of this Section 2.04.

SECTION 2.05. Proration.

(a) For purposes of this Section 2.05:

(i) "Company Stock Number" shall mean the number of shares of Company Common Stock that are issued and outstanding at the Effective Time (excluding any shares of Company Common Stock to be canceled pursuant to Section 2.01(b)).

(ii) "Aggregate Transaction Value" shall mean the product of (x) the Company Stock Number, multiplied by (y) the Cash Consideration.

All outstanding shares of capital stock of the Company are, and all shares which may be issued prior to the Closing will be, when issued, duly authorized, validly issued, fully paid and nonassessable and will be delivered free and clear of all Liens (other than Liens created by or imposed upon the holders thereof) and not subject to preemptive rights or similar rights.

There is no condition or circumstances that would reasonably be expected to give rise to or provide a basis for the assertion of a claim by any person to the effect that such person is entitled to acquire or receive any shares of capital stock or other securities of the Company. The Company is not a party to any voting agreement with respect to the voting of any such securities. As of the date of this Agreement, the aggregate number of "Shares"

(as such term is defined in the Stockholder Agreement) held by Signatory Stockholders collectively represent approximately 22% of the shares of Company Common Stock outstanding. Section 3.03 of the Company Disclosure Schedule sets forth a complete and accurate list of all securities or other beneficial ownership interests in any other entity beneficially owned, directly or indirectly, by the Company, other than the capital stock of, or other equity interests in, its subsidiaries. All outstanding shares of Company Common Stock, all outstanding Stock Options, Warrants and all outstanding shares of capital stock of each subsidiary of the Company have been issued and granted in compliance with (i) all applicable securities laws and other applicable laws and (ii) all requirements set forth in applicable Contracts, except in each case where the failure to comply would not subject the Company to material liability.

(c) The Surviving Corporation shall, at its option, for a period of not less than six years after the Effective Time, either (i) maintain the Company's current directors' and officers' liability insurance covering acts or omissions occurring at or prior to the Effective Time ("D&O Insurance") with respect to those persons who are currently covered by the Company's directors' and officers' liability insurance policy on terms with respect to such coverage and amount no less favorable than those of such policy in effect on the date hereof or (ii) cause to be provided

coverage no less favorable to such directors or officers, as the case may be, than the D&O Insurance, in each case so long as the annual premium therefor would not be in excess of 150% of the last annual premium paid for the D&O Insurance prior to the date of this Agreement (such 150% amount the "Maximum Premium"); provided that if the annual premium for such coverage exceeds the Maximum Premium, Parent shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Premium.

Provisions of the JV Termination Agreements

1): The JV Termination Agreements shall provide for the termination of all obligations of the Company under any agreements between and among (a) the Company (including affiliates thereof), (b) such Joint Ventures and (c) any of the other investors (including their affiliates) in such Joint Venture, in each case relating solely to such Joint Venture and not to any other business relationships between any of the parties referred to in (a) and any of the parties referred to in (c) provided, however, that the registration rights agreement and the non-solicitation provisions and no hire provisions of Section 17(b) of the Shareholders' Agreement dated as of December 27, 2000, by and among Jupiter Media Metrix, Inc, and IPSOS S.A. ("IPSOS") with respect to JMXI Latin America as provided in the settlement agreement between the Company and IPSOS may remain in full force and effect pursuant to said agreements executed between the parties as previously provided to Parent. The JV Termination Agreements shall provide that the transactions contemplated by them shall be consummated by the Effective Time.

For the avoidance of doubt, the matters described in this Item 2 shall not be included in the definition of JV Termination Agreements for the purposes of determining JV Termination Expenses as such expenses are addressed below in Item 4, but the terms of the effectuation of such matters shall be subject to the same approval rights of Parent of the JV Termination Agreements as are provided in Section 6.17.
3): The JV Termination Agreements shall include, without limitation, the termination of any and all non-competition agreements between and among the entities described in subclauses (a), (b) and (c) of clause (1) above.
4): "Restructuring Costs" means all expenses (whether paid in cash, stock or other consideration or through the incurring of liabilities in any form), associated with termination of operations or the cancellation of any licenses (including without limitation severance payments to employees, lease termination, etc.) pertaining to (1) JMMJ (but only to the extent such Restructuring Costs for JMMJ, exceed $1,000,000) and (2) MMPL (each as described in Item 2) above.
