CUSIP NUMBER 344067103 Page 3 of 8 Pages Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by CMGI, Inc. that it is the beneficial owner of any of the Common Stock referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Act"), or for any other purpose, and such beneficial ownership is expressly disclaimed. Item 1. Security and Issuer. ------------------- This statement on Schedule 13D relates to the Common Stock of Flycast Communications Corporation, a Delaware corporation ("Flycast" or "Issuer"). The principal executive offices of Flycast are located at 181 Fremont Street, San Francisco, California 94105. Item 2. Identity and Background. ----------------------- The name of the corporation filing this statement is CMGI, Inc., a Delaware corporation ("CMGI"). CMGI's principal business is developing and operating Internet and direct marketing companies and funding synergistic Internet companies through its affiliated venture funds. The address of the principal executive offices of CMGI is 100 Brickstone Square, Andover, Massachusetts 01810. Set forth on Schedule -------- A is the name, residence or business address, present principal - occupation or employment and the name, principal business and address of any corporation or other organization in which such employment is conducted and citizenship of each of CMGI's directors and executive officers, as of the date hereof. Neither CMGI nor, to CMGI's best knowledge, any person named on Schedule A hereto is required to disclose legal proceedings pursuant ---------- to Items 2(d) or 2(e). Item 3. Source and Amount of Funds or Other Consideration. ------------------------------------------------- Pursuant to an Agreement and Plan of Merger, dated as of September 29, 1999 (the "Merger Agreement"), among CMGI, Freemont Corporation, a Delaware corporation and a wholly owned subsidiary of CMGI ("Merger Sub"), and Flycast and, subject to the conditions set forth therein (including approval by stockholders of Flycast), Merger Sub will merge with and into Flycast and Flycast will become a wholly owned subsidiary of CMGI (such events constituting the "Merger"). Once the Merger is consummated, Merger Sub will cease to exist as a corporation and all of the business, assets, liabilities and obligations of Merger Sub will be merged into Flycast with Flycast remaining as the surviving corporation (the "Surviving Corporation"). As a result of the Merger, each outstanding share of Flycast Common Stock, other than shares owned by CMGI, will be converted into

CUSIP NUMBER 344067103 Page 4 of 8 Pages the right to receive 0.4738 of a share (the "Exchange Ratio") of CMGI Common Stock, and each outstanding option to purchase Flycast Common Stock under Flycast's stock option plans (each a "Flycast Common Stock Option") will be assumed by CMGI (each an "Assumed Option") and will become an option to purchase that number of shares of CMGI Common Stock as is equal (subject to rounding) to the number of shares of Flycast Common Stock that was subject to such option immediately prior to the Merger, multiplied by the Exchange Ratio. The exercise price of each Assumed Option will be equal to the quotient determined by dividing the aggregate exercise price for the shares of Flycast Common Stock purchasable pursuant to the Flycast Stock Option immediately prior to the effective time of the Merger by the number of full shares of CMGI Common Stock deemed purchasable pursuant to the Flycast Stock Option in accordance with the foregoing, rounded up to the nearest whole cent. The foregoing summary of the Merger is qualified in its entirety by reference to the copy of the Merger Agreement included as Exhibit 1 to this Schedule 13D and incorporated herein in its entirety by this reference. In connection with the Merger Agreement, CMGI and the Issuer entered into a Stock Option Agreement, dated as of September 29, 1999 (the "Option Agreement"). The Option Agreement grants CMGI the right, under certain circumstances, to purchase up to 3,036,750 shares of Issuer Common Stock at a price of $47.53 per share (subject to adjustment); provided, however, that the number of shares issuable to CMGI pursuant to the Option Agreement shall not exceed 19.9% of the outstanding shares of the Flycast Common Stock (the "Option"). The foregoing summary of the Option Agreement and the Option is qualified in its entirety by reference to the copy of the Option Agreement included as Exhibit 2 to this Schedule 13D and incorporated herein in its entirety by this reference. Item 4. Purpose of Transaction. ---------------------- (a)-(b) As described in Item 3 above, this statement relates to the Merger of Merger Sub with and into Flycast in a statutory merger pursuant to the Delaware General Corporation Law and to the transactions contemplated by the Option Agreement. At the effective time of the Merger, the separate existence of Merger Sub will cease to exist and Flycast will continue as the Surviving Corporation and as a wholly owned subsidiary of CMGI. Holders of outstanding Flycast Common Stock will receive, in exchange for each share of Flycast Common Stock held by them, 0.4738 shares of CMGI Common Stock. CMGI will assume the outstanding options issued under Flycast stock option plans.

CUSIP NUMBER 344067103 Page 5 of 8 Pages As an inducement to CMGI to enter into the Merger Agreement, each of the individuals and the entities set forth on Schedule B, each a ---------- stockholder of Flycast (collectively, the "Stockholders"), has executed a Stockholder Agreement, dated as of September 29, 1999, with CMGI (the "Stockholder Agreement"), and, by doing so, has irrevocably appointed CMGI as such stockholder's lawful attorney and proxy. Such proxy gives CMGI the limited right to vote each of the 7,371,107 shares of Flycast Common Stock beneficially owned by the Stockholders in all matters related to the Merger. The shared voting power with the Stockholders relates to the same 7,371,107 shares of Issuer Common Stock (the "Shares"). The foregoing summary of the Stockholder Agreement is qualified in its entirety by reference to the copy of the Stockholder Agreement included as Exhibit 3 to this Schedule 13D and incorporated herein in its entirety by reference. In exercising its right to vote the Shares as lawful attorney and proxy of the Stockholders, CMGI (or any nominee of CMGI) will be limited, at every Flycast stockholders meeting and every written consent in lieu of such meeting, to vote the shares in favor of approval of the Merger and the Merger Agreement. The Stockholders may vote the Shares on all other matters. The Stockholder Agreement terminates upon the earlier to occur of (i) such date and time as the Merger shall become effective in accordance with the terms and provisions of the Merger Agreement and (ii) the date of termination of the Merger Agreement. (c) Not applicable. (d) It is anticipated that, upon consummation of the Merger, the directors of the Surviving Corporation shall be the current directors of Merger Sub. It is anticipated that the initial officers of the Surviving Corporation shall be the officers of Merger Sub, until their respective successors are duly elected or appointed and qualified. (e) Other than as a result of the Merger described in Item 3 above, not applicable. (f) Not applicable. (g) Upon consummation of the Merger, the Certificate of Incorporation of Flycast, as in effect immediately prior to the Merger, shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended as provided by Delaware Law and such Certificate of Incorporation; provided, however, that Article IV of the Certificate of Incorporation of the Surviving Corporation shall be amended to read as follows: "The total number of shares of all classes of stock which the Corporation shall have authority to issue is 1,000, all of which shall

CUSIP NUMBER 344067103 Page 6 of 8 Pages consist of Common Stock, $.01 par value per share." Upon consummation of the Merger, the By-laws of Merger Sub, as in effect immediately prior to the Merger shall be the By-laws of the Surviving Corporation until hereafter amended; provided, however, that the name of the corporation set forth in the By-laws shall be changed to the name of the Issuer. In addition, each of the Merger Agreement and the Option Agreement may have the effect of impeding the acquisition of control of Issuer by any person other than CMGI. (h)-(i) If the Merger is consummated as planned, the Flycast Common Stock will be deregistered under the Act and delisted from the Nasdaq National Market. (j) Other than as described above, CMGI currently has no plan or proposals which relate to, or may result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D (although CMGI reserves the right to develop such plans). Item 5. Interest in Securities of the Issuer. ------------------------------------ (a)-(b) As a result of the Stockholder Agreement, CMGI may be deemed to be the beneficial owner of at least 10,407,857 shares of Issuer Common Stock. Such Issuer Common Stock constitutes approximately 68.20% of the issued and outstanding shares of Issuer Common Stock. Schedule B sets forth the applicable information required by Item 2 with respect to each of the Stockholders with whom the power to vote is shared. (c)-(e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect --------------------------------------------------------------------- to Securities of the Issuer. --------------------------- Other than the Merger Agreement, the Option Agreement and the Stockholder Agreement, to the best knowledge of CMGI, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons or entities listed in Item 2 and between such persons or entities and any person or entity with respect to any securities of Flycast, including but not limited to transfer of voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.

As soon as reasonably practicable after the ------------------- Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of the Company Common Stock (the "Certificates") whose shares were converted pursuant to Section 2.1 into the right to receive shares of Buyer Common Stock (i) a 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 such form and have such other provisions as the Buyer may reasonably specify) and (ii) instructions for effecting the surrender of the Certificates in exchange for certificates representing shares of Buyer Common Stock (plus cash in lieu of fractional shares, if any, of Buyer Common Stock and any dividends or distributions as provided below). Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by the Buyer, together with such letter of transmittal, duly 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 a certificate representing that number of whole shares of Buyer Common Stock which such holder has the right to receive pursuant to the provisions of this Article II plus cash in lieu of fractional shares pursuant to Section 2.2(e) and any dividends or distributions pursuant to Section 2.2(c), and the Certificate so surrendered shall immediately be canceled. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, a certificate representing the proper number of shares of Buyer Common Stock plus cash in lieu of fractional shares pursuant to Section 2.2(e) and any dividends or distributions pursuant to Section 2.2(c) may be issued and paid to a person other than the person in whose name the Certificate so surrender is registered, if such Certificate is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the certificate representing shares of Buyer Common Stock plus cash in lieu of fractional shares pursuant to Section 2.2(e) and any dividends or distributions pursuant to Section 2.2(c) as contemplated by this Section 2.2. (c) Distributions with Respect to Unexchanged Shares. No dividends ------------------------------------------------ or other distributions declared or made after the Effective Time with respect to Buyer Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Buyer Common Stock represented thereby and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.2(e) until the holder of record of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be issued and paid to the record holder of the Certificate, (i) certificates representing whole shares of Buyer Common Stock issued -6-

in exchange therefor, without interest, (ii) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of Buyer Common Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole shares of Buyer Common Stock, and (iii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Buyer Common Stock. (d) No Further Ownership Rights in Company Common Stock. All shares --------------------------------------------------- of Buyer Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms hereof (including any cash or other distributions paid pursuant to Sections 2.2(c) or 2.2(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Common Stock, and from and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock which 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 any reason, they shall be canceled and exchanged as provided in this Article II. (e) No Fractional Shares. No certificate or scrip representing -------------------- fractional shares of Buyer Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a stockholder of the Buyer. 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 share of Buyer Common Stock (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of Buyer Common Stock multiplied by the average of the last reported sales prices of the Buyer Common Stock on the Nasdaq National Market during the ten (10) consecutive trading days ending on and including the last trading day prior to the Effective Time. (f) Termination of Exchange Fund. Any portion of the Exchange Fund ---------------------------- which remains undistributed to the holders of Company Common Stock for 180 days after the Effective Time shall be delivered to the Buyer, upon demand, and any holder of Company Common Stock who has not previously complied with this Section 2.2 shall thereafter look only to the Buyer for payment of its claim for Buyer Common Stock, any cash in lieu of fractional shares of Buyer Common Stock and any dividends or distributions with respect to Buyer Common Stock. -7-

(g) No Liability. To the extent permitted by applicable law, none of ------------ the Buyer, the Transitory Subsidiary, the Company, the Surviving Corporation or the Exchange Agent shall be liable to any holder of shares of Company Common Stock or Buyer Common Stock, as the case may be, for such shares (or dividends or distributions with respect thereto) 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 one year after the Effective Time (or immediately prior to such earlier date on which any shares of Buyer Common Stock, and any cash payable to the holder of such Certificate pursuant to this Article II or any dividends or distributions payable to the holder of such Certificate would otherwise escheat to or become the property of any Governmental Entity (as defined in Section 3.3(c))), any such shares of Buyer Common Stock or cash, dividends or distributions in respect of such Certificate 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) Withholding Rights. Each of the Buyer and the Surviving ------------------ Corporation shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any other applicable provision of law. To the extent that amounts are so withheld by the Surviving Corporation or the Buyer, as the case may be, 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 the Surviving Corporation or the Buyer, as the case may be. (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 the Surviving Corporation, the posting by such person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Buyer Common Stock and any cash in lieu of fractional shares, and unpaid dividends and distributions on shares of Buyer Common Stock deliverable in respect thereof pursuant to this Agreement.

(b) Notwithstanding any other provision of this Agreement, the Option may not be exercised for a number of Shares as would, as of the date of the Exercise Notice, result in a Notional Total Profit (as defined below) of more than the Profit Limit and, if exercise of the Option otherwise would exceed the Profit Limit, the Grantee, at its -58-

discretion, may increase the Purchase Price for that number of Shares set forth in the Exercise Notice so that the Notional Total Profit shall not exceed the Profit Limit; provided, that nothing in this sentence shall restrict any -------- exercise of the Option permitted hereby on any subsequent date at the Purchase Price set forth in Section 1(a) hereof. (c) As used herein, the term "Total Profit" shall mean the aggregate amount (before taxes) of the following: (i) the amount of cash received by Grantee pursuant to Section 8.3(c) of the Merger Agreement, and (ii) (x) the cash amounts (net of customary brokerage commissions paid in connection with the transaction) received by Grantee pursuant to the sale of Shares (or any other securities into which such Shares are converted or exchanged) to any unaffiliated party, less (y) the Grantee's purchase price for such Shares. (d) As used herein, the term "Notional Total Profit" with respect to any number of Shares as to which Grantee may propose to exercise the Option shall be the Total Profit determined as of the date of the Exercise Notice assuming that the Option were exercised on such date for such number of Shares and assuming that such Shares, together with all other Shares held by Grantee and its affiliates as of such date, were sold for cash at the closing market price for the Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions). 9. Put. --- (a) At any time during which the Option is exercisable under this Agreement (the "Repurchase Period"), upon demand by the Grantee, the Grantee shall have the right to sell to the Grantor (or any successor entity thereof) and Grantor (or such successor entity, shall be obligated to repurchase from the Grantee (the "Put"), all or any portion of the Option, to the extent not previously exercised, at the price set forth in subparagraph (i) below, and/or all or any portion of the Shares purchased by the Grantee pursuant thereto, at a price set forth in subparagraph (ii) below: (i) the difference between the "Market/Tender Offer Price" for shares of Common Stock as of the date (the "Notice Date") notice of exercise of the Put is given to the other party (defined as the greater of (A) the price per share offered as of the Notice Date pursuant to any tender or exchange offer or other Acquisition Proposal which was made prior to the Notice Date and not terminated or withdrawn as of the Notice Date (the "Tender Price") or (B) the average of the closing prices of shares of Common Stock on the Nasdaq National Market for the ten (10) trading days immediately preceding the Notice Date (the "Market Price")), and the Purchase Price multiplied by the number of Shares purchasable pursuant to the Option (or portion thereof with respect to which the Grantee is exercising its rights under this Section 9), but only if the Market/Tender Offer Price is greater than the Purchase Price; -59-

(ii) the Purchase Price paid by the Grantee for the Shares acquired pursuant to the Option plus the difference between the Market/Tender Offer Price and the Purchase Price, but only if the Market/Tender Offer Price is greater than the Purchase Price, multiplied by the number of Shares so purchased; (b) In the event Grantee exercises its rights under this Section 9, the Grantor shall, within ten business days of the Notice Date, pay the required amount (the "Repurchase Price") to the Grantee in immediately available funds and the Grantee shall surrender to the Grantor the Option or the certificates evidencing the Shares purchased by the Grantee pursuant thereto, and the Grantee shall represent and warrant that it owns such shares and that such shares are then free and clear of all liens, claims, charges and encumbrances of any kind or nature whatsoever, other than any of the same created by the Grantor or its affiliates. (c) To the extent that the Grantor is prohibited under applicable law or regulation, or as a consequence of administrative policy, from repurchasing the Option and/or Shares in full, the Grantor shall immediately so notify the Grantee and thereafter deliver or cause to be delivered, from time to time, to the Grantee the portion of the Repurchase Price that it is no longer prohibited from delivering within five business days after the date on which the Grantor is no longer so prohibited; provided that, if the Grantor at any time after delivery of a notice of exercise of the Put pursuant to Section 9(a) is prohibited under applicable law or regulation, or as a consequence of administrative policy, from delivering to the Grantee the Repurchase Price in full (and the Grantor hereby undertakes to use its best efforts to obtain all required regulatory and legal approvals and to file any required notices as promptly as practicable in order to accomplish such repurchase), the Grantee may revoke its notice of the exercise of the Put whether in whole or to the extent of the prohibition, whereupon, in the latter case, the Grantor shall promptly (1) deliver to the Grantee that portion of the Repurchase Price that the Grantor is not prohibited from delivering and (2) deliver to the Grantee as appropriate, (A) a new Agreement evidencing the right of the Grantee to purchase that number of shares of Common Stock obtained by multiplying the number of shares of Common Stock for which the surrendered Agreement was exercisable at the time of delivery of the notice of exercise of the Put by a fraction, the numerator of which is the Repurchase Price less the portion of the Repurchase Price previously delivered to the Grantee and the denominator of which is the Repurchase Price, and/or (B), a certificate for the Shares the Grantor is then so prohibited from repurchasing. 10. Expenses. Each party hereto shall pay its own expenses incurred in -------- connection with this Agreement, except as otherwise specifically provided herein. 11. Specific Performance. The Grantor acknowledges that if the Grantor -------------------- fails to perform any of its obligations under this Agreement, immediate and irreparable harm or injury would be caused to the Grantee for which money damages would not be an -60-

adequate remedy. In such event, the Grantor agrees that the Grantee shall have the right, in addition to any other rights it may have, to specific performance of this Agreement. Accordingly, if the Grantee should institute an action or proceeding seeking specific enforcement of the provisions hereof, the Grantor hereby waives the claim or defense that the Grantee has an adequate remedy at law and hereby agrees not to assert in any such action or proceeding the claim or defense that such a remedy at law exists. The Grantor further agrees to waive any requirements for the securing or posting of any bond in connection with obtaining any such equitable relief. 12. Notice.

Pursuant to the terms of the Agreement and Plan of Merger, dated as of __________ ___, 1999 (the "Agreement"), between [Buyer], a Delaware corporation ("Acquiror"), a subsidiary of Acquiror ("Sub") and the Company, Sub will be merged with and into the Company (the "Merger") and the Company will be the surviving corporation. As a result of the Merger, I may receive shares of common stock, par value $.01 per share, of Acquiror (the "Acquiror Common Stock") in exchange for shares owned by me of common stock of the Company ("Company Common Stock"). 1. Compliance with the Act. I represent, warrant and covenant to ----------------------- Acquiror that in the event I receive any Acquiror Common Stock as a result of the Merger: (a) I shall not make any sale, transfer or other disposition of the Acquiror Common Stock in violation of the Act or the Rules and Regulations. (b) I have carefully read this letter and the Agreement and discussed the requirements of such documents and other applicable limitations upon my ability to sell, transfer or otherwise dispose of the Acquiror Common Stock to the extent I felt necessary, with my counsel or counsel for the Company. (c) I have been advised that the issuance of Acquiror Common Stock to me pursuant to the Merger will be registered with the Commission under the Act on a Registration Statement on Form S-4. However, I have also been advised that, since at the time the Merger is submitted for a vote of the stockholders of the Company, I may be deemed to have been an affiliate of the Company and the distribution by me of the Acquiror Common Stock has not been registered under the Act, I may not sell, transfer or otherwise dispose of the Acquiror Common Stock issued to me in the Merger unless (i) such sale, transfer or other disposition as been registered under the Act, (ii) such sale, transfer or disposition is made in conformity with Rule 145 promulgated by the -75-

Commission under the Act, or (iii) in the opinion of counsel reasonably acceptable to Acquiror, or pursuant to a "no action" letter obtained by the undersigned from the staff of the Commission, such sale, transfer or other disposition is otherwise exempt from registration under the Act. (d) I understand that Acquiror is under no obligation to register the sale, transfer or disposition of the Acquiror Common Stock by me or on my behalf under the Act. (e) I also understand that stop transfer instructions will be given to the Acquiror's transfer agent with respect to the Acquiror Common Stock and that there will be placed on the Certificates for the Acquiror Common Stock issued to me, or any substitutions therefor, a legend stating in substance: "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT, DATED _________ ___, 1999 BETWEEN THE REGISTERED HOLDER HEREOF AND [Buyer], A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF __________." (f) I also understand that unless the transfer by me of my Acquiror Common Stock has been registered under the Act or is a sale made in conformity with the provisions of Rule 145, Acquiror reserves the right to put the following legend on the certificates issued to my transferee: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933." -76-

It is understood and agreed that the legends set forth in paragraphs E and F above shall be removed by delivery of substitute certificates without such legend if such legend is not required for purposes of the Act or this Agreement. It is understood and agreed that such legends and the stop orders referred to above will be removed if (i) one year shall have elapsed from the date the undersigned acquired the Acquiror Common Stock received in the Merger and the provisions of Rule 145(d)(2) are then available to the undersigned, (ii) two years shall have elapsed from the date the undersigned acquired Acquiror Common Stock received in the Merger and the provisions of Rule 145(d)(3) are then available to the undersigned, or (iii) Acquiror has received either an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to Acquiror, or a "no action" letter obtained by the undersigned from the staff of the Commission, to the effect that the restrictions imposed by Rule 145 under the Act no longer apply to the undersigned. 2. Certain Tax Matters. The undersigned does not intend to take a ------------------- position on any federal or state income tax return that is inconsistent with the treatment of the Merger as a tax-free reorganization for federal or state income tax purposes. Very truly yours, _____________________________________ Signature _____________________________________ Print Name Accepted this ___ day of _____________ ___, 1999 by [Buyer] By:______________________________ Name:____________________________ Title:___________________________ -77-

Conditions to Delivery of Shares. The Grantor's obligation to deliver -------------------------------- Shares upon exercise of the Option is subject only to the conditions that: (a) No preliminary or permanent injunction or other order issued by any federal or state court of competent jurisdiction in the United States prohibiting the delivery of the Shares shall be in effect; and (b) Any applicable waiting periods under the HSR Act shall have expired or been terminated. 3.

On the Closing Date, the Grantor will deliver to the Grantee a certificate or certificates, duly endorsed (or accompanied by duly executed stock -2-

powers), representing the Shares in the denominations designated by the Grantee in its Exercise Notice and the Grantee will purchase such Shares from the Grantor at the price per Share equal to the Purchase Price.

Each of the parties hereto will use its best efforts to obtain consents of all third parties and governmental authorities, if any, necessary to the consummation of the transactions contemplated. 7. Registration Rights. ------------------- (a) In the event that the Grantee shall desire to sell any of the Shares within two years after the purchase of such Shares pursuant hereto, and such sale requires, in the opinion of counsel to the Grantee, which opinion shall be reasonably satisfactory to the Grantor and its counsel, registration of such Shares under the Securities Act, the Grantor will cooperate with the Grantee and any underwriters in registering such Shares for resale, including, without limitation, promptly filing a registration statement which complies with the requirements of applicable federal and state securities laws and entering into an underwriting agreement with such underwriters upon such terms and conditions as are customarily contained in underwriting agreements with respect to secondary distributions; provided that the Grantor shall not be required to have declared effective more than two registration statements hereunder and shall be entitled to delay the filing or effectiveness of any registration statement for up to 120 days if the offering would, in the judgment of the Board of Directors of the Grantor, require premature disclosure of any material corporate development or otherwise interfere with or adversely affect any pending or proposed offering of securities of the Grantor or any other material transaction involving the Grantor. (b) If the Common Stock is registered pursuant to the provisions of this Section 7, the Grantor agrees (i) to furnish copies of the registration statement and the -4-

prospectus relating to the Shares covered thereby in such numbers as the Grantee may from time to time reasonably request and (ii) if any event shall occur as a result of which it becomes necessary to amend or supplement any registration statement or prospectus, to prepare and file under the applicable securities laws such amendments and supplements as may be necessary to keep available for at least 90 days a prospectus covering the Common Stock meeting the requirements of such securities laws, and to furnish to the Grantee such numbers of copies of the registration statement and prospectus as amended or supplemented as may reasonably be requested. The Grantor shall bear the cost of the registration, including, but not limited to, all registration and filing fees, printing expenses, and fees and disbursements of counsel and accountants for the Grantor, except that the Grantee shall pay the fees and disbursements of its counsel and the underwriting fees and selling commissions applicable to the Shares sold by the Grantee. The Grantor shall indemnify and hold harmless Grantee, its affiliates and its officers and directors from and against any and all losses, claims, damages, liabilities and expenses arising out of or based upon any statements contained in, omissions or alleged omissions from, each registration statement filed pursuant to this paragraph; provided, however, that this -------- ------- provision does not apply to any loss, liability, claim, damage or expense to the extent it arises out of any statement or omission made in reliance upon and in conformity with written information furnished to the Grantor by the Grantee, its affiliates or its officers expressly for use in any registration statement (or any amendment thereto) or any preliminary prospectus filed pursuant to this paragraph. The Grantor shall also indemnify and hold harmless each underwriter and each person who controls any underwriter within the meaning of either the Securities Act or the Securities Exchange Act of 1934 against any and all losses, claims, damages, liabilities and expenses arising out of or based upon any statements contained in, omissions or alleged omissions from, each registration statement filed pursuant to this paragraph; provided, however, that -------- ------- this provision does not apply to any loss, liability, claim, damage or expense to the extent it arises out of any statement or omission made in reliance upon and in conformity with written information furnished to the Grantor by the underwriters expressly for use in any registration statement (or any amendment thereto) or any preliminary prospectus filed pursuant to this paragraph. 8. Profit Limitation. ----------------- (a) Notwithstanding any other provision of this Agreement, in no event shall the Grantee's Total Profit (as hereinafter defined) exceed $30 million (the "Profit Limit") and, if it otherwise would exceed such amount, the Grantee, at its sole election, shall either (i) deliver to the Grantor for cancellation Shares previously purchased by Grantee, (ii) pay cash to the Grantor, (iii) receive a smaller termination fee under Section 8.3 of the Merger Agreement or (iv) undertake any combination thereof, so that Grantee's Total Profit shall not exceed the Profit Limit after taking into account the foregoing actions. -5-

(b) Notwithstanding any other provision of this Agreement, the Option may not be exercised for a number of Shares as would, as of the date of the Exercise Notice, result in a Notional Total Profit (as defined below) of more than the Profit Limit and, if exercise of the Option otherwise would exceed the Profit Limit, the Grantee, at its discretion, may increase the Purchase Price for that number of Shares set forth in the Exercise Notice so that the Notional Total Profit shall not exceed the Profit Limit; provided, that nothing in this -------- sentence shall restrict any exercise of the Option permitted hereby on any subsequent date at the Purchase Price set forth in Section 1(a) hereof. (c) As used herein, the term "Total Profit" shall mean the aggregate amount (before taxes) of the following: (i) the amount of cash received by Grantee pursuant to Section 8.3(c) of the Merger Agreement, and (ii) (x) the cash amounts (net of customary brokerage commissions paid in connection with the transaction) received by Grantee pursuant to the sale of Shares (or any other securities into which such Shares are converted or exchanged) to any unaffiliated party, less (y) the Grantee's purchase price for such Shares. (d) As used herein, the term "Notional Total Profit" with respect to any number of Shares as to which Grantee may propose to exercise the Option shall be the Total Profit determined as of the date of the Exercise Notice assuming that the Option were exercised on such date for such number of Shares and assuming that such Shares, together with all other Shares held by Grantee and its affiliates as of such date, were sold for cash at the closing market price for the Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions). 9. Put. --- (a) At any time during which the Option is exercisable under this Agreement (the "Repurchase Period"), upon demand by the Grantee, the Grantee shall have the right to sell to the Grantor (or any successor entity thereof) and Grantor (or such successor entity, shall be obligated to repurchase from the Grantee (the "Put"), all or any portion of the Option, to the extent not previously exercised, at the price set forth in subparagraph (i) below, and/or all or any portion of the Shares purchased by the Grantee pursuant thereto, at a price set forth in subparagraph (ii) below: (i) the difference between the "Market/Tender Offer Price" for shares of Common Stock as of the date (the "Notice Date") notice of exercise of the Put is given to the other party (defined as the greater of (A) the price per share offered as of the Notice Date pursuant to any tender or exchange offer or other Acquisition Proposal which was made prior to the Notice Date and not terminated or withdrawn as of the Notice Date (the "Tender Price") or (B) the average of the closing prices of shares of -6-

Common Stock on the Nasdaq National Market for the ten (10) trading days immediately preceding the Notice Date (the "Market Price")), and the Purchase Price multiplied by the number of Shares purchasable pursuant to the Option (or portion thereof with respect to which the Grantee is exercising its rights under this Section 9), but only if the Market/Tender Offer Price is greater than the Purchase Price; (ii) the Purchase Price paid by the Grantee for the Shares acquired pursuant to the Option plus the difference between the Market/Tender Offer Price and the Purchase Price, but only if the Market/Tender Offer Price is greater than the Purchase Price, multiplied by the number of Shares so purchased; (b) In the event Grantee exercises its rights under this Section 9, the Grantor shall, within ten business days of the Notice Date, pay the required amount (the "Repurchase Price") to the Grantee in immediately available funds and the Grantee shall surrender to the Grantor the Option or the certificates evidencing the Shares purchased by the Grantee pursuant thereto, and the Grantee shall represent and warrant that it owns such shares and that such shares are then free and clear of all liens, claims, charges and encumbrances of any kind or nature whatsoever, other than any of the same created by the Grantor or its affiliates. (c) To the extent that the Grantor is prohibited under applicable law or regulation, or as a consequence of administrative policy, from repurchasing the Option and/or Shares in full, the Grantor shall immediately so notify the Grantee and thereafter deliver or cause to be delivered, from time to time, to the Grantee the portion of the Repurchase Price that it is no longer prohibited from delivering within five business days after the date on which the Grantor is no longer so prohibited; provided that, if the Grantor at any time after delivery of a notice of exercise of the Put pursuant to Section 9(a) is prohibited under applicable law or regulation, or as a consequence of administrative policy, from delivering to the Grantee the Repurchase Price in full (and the Grantor hereby undertakes to use its best efforts to obtain all required regulatory and legal approvals and to file any required notices as promptly as practicable in order to accomplish such repurchase), the Grantee may revoke its notice of the exercise of the Put whether in whole or to the extent of the prohibition, whereupon, in the latter case, the Grantor shall promptly (1) deliver to the Grantee that portion of the Repurchase Price that the Grantor is not prohibited from delivering and (2) deliver to the Grantee as appropriate, (A) a new Agreement evidencing the right of the Grantee to purchase that number of shares of Common Stock obtained by multiplying the number of shares of Common Stock for which the surrendered Agreement was exercisable at the time of delivery of the notice of exercise of the Put by a fraction, the numerator of which is the Repurchase Price less the portion of the Repurchase Price previously delivered to the Grantee and the denominator of which is the Repurchase Price, and/or (B), a certificate for the Shares the Grantor is then so prohibited from repurchasing. -7-

10. Expenses. Each party hereto shall pay its own expenses incurred in -------- connection with this Agreement, except as otherwise specifically provided herein. 11. Specific Performance.

Accordingly, if the Grantee should institute an action or proceeding seeking specific enforcement of the provisions hereof, the Grantor hereby waives the claim or defense that the Grantee has an adequate remedy at law and hereby agrees not to assert in any such action or proceeding the claim or defense that such a remedy at law exists. The Grantor further agrees to waive any requirements for the securing or posting of any bond in connection with obtaining any such equitable relief. 12. Notice.

Capitalized terms used and not otherwise defined herein shall have the respective meanings assigned to them in the Merger Agreement referred to below. WHEREAS, as of the date hereof, the Stockholders collectively own of record and beneficially shares of capital stock of Flycast Communications Corporation, a Delaware corporation (the "Company"), as set forth on Schedule I hereto (such shares or any other voting or equity of securities of the Company, hereafter acquired by any Stockholder prior to the termination of this Agreement, being referred to herein collectively as the "Shares"); WHEREAS, concurrently with the execution of this Agreement, Acquiror and the Company are entering into an Agreement and Plan of Merger, dated as of the date hereof (the "Merger Agreement"), pursuant to which, upon the terms and subject to the conditions thereof, a subsidiary of Buyer will be merged with and into the Company, and the Company will be the surviving corporation (the "Merger"); and WHEREAS, as a condition to the willingness of the Company and Acquiror to enter into the Merger Agreement, Acquiror has requested that the Stockholders agree, and in order to induce Acquiror to enter into the Merger Agreement, the Stockholders are willing to agree to vote in favor of adopting the Merger Agreement and approving the Merger, upon the terms and subject to the conditions set forth herein.
