[REVERSE SIDE OF NOTE]

COVAD COMMUNICATIONS GROUP, INC.
COVAD COMMUNICATIONS COMPANY

12% Senior Secured Convertible Note due 2011

Section 1.               Principal and Interest.

(a)               Subject to Section 1(d), the Company will pay the principal of this Note on March  15, 2011 (the “Final Maturity”). The Company, jointly and severally, promises to pay interest on the principal amount of this Note on each Interest Payment Date, as set forth below, at the rate per annum shown above.

(b)              Interest will be payable semiannually (to the holders of record of the Notes at the close of business on the March  1 or September 1 immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing September 15, 2006. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from March      , 2006 (the “Issue Date”). Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. The Company shall pay interest on overdue principal and premium, if any, and interest on overdue installments of interest, to the extent lawful, at a rate per annum that is 2% in excess of the rate otherwise payable.

(c)               The Company will have the option to pay interest in cash or through the issuance of notes, other than the notes comprising the first $40,000,000.00 principal amount of Notes issued on the date hereof (the “Initial Notes”), which shall be issued as part of the same series as the Initial Notes (the “Additional Notes” and, together with the Initial Notes, the “Notes”). The Additional Notes will be identical to the Initial Notes, except that interest will begin to accrue from the date they are issued rather than the Issue Date. The Company shall provide written or oral notice to the Holders five Business Days prior to an Interest Payment Date of whether such interest payment will be made in cash, by the issuance of Additional Notes or by a combination thereof. If the Company fails to deliver such notice in such time period, interest for the period for which the notice was not properly given shall be paid by the issuance of Additional Notes. Any cash interest payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

(d)              Notwithstanding, the first sentence of Section 1(a), in the event that: (i) (A) Operating elects under Section 9.2.4 of that certain Agreement for XGDSL Services, dated of even date herewith, between Operating and EarthLink, Inc. (“EarthLink”) (the “Services Agreement”) not to proceed with the Phase II Build Out (as defined in the Services Agreement) by written notice to EarthLink (“Phase II Notice”), or (B) Operating receives from EarthLink notice of a Substantial Performance Failure, as defined in and in accordance with the terms of, Section 4.5 of the Services Agreement and Exhibit 2 of the Services Agreement (the “Substantial Performance Notice’) and (ii) with respect to subsection (d)(i)(A), on the date of the Phase II Notice EarthLink holds at least two-thirds of the outstanding aggregate principal amount of the Notes and of the Primary Shares, then EarthLink may, in either case and at its option, at any time

3

during the 30-day period following receipt of the Phase II Notice or the Substantial Performance Notice, as applicable, by written notice to the Company (the “Election Notice”), require the Company to pay the remaining principal amount of the Notes held by EarthLink on the date of the Election Notice (“Amortized Notes”) in four equal annual installments due March 15 of each year, commencing on March 15, 2007 and ending on March 15, 2010 (the “Principal Installments”); provided, however, that if such Election Notice is made after any of such dates the principal on the Amortized Notes will be paid ratably on the remaining dates. Accrued interest, if any, on the Principal Installments shall be paid in accordance with Section 1(b). From and after the date of the Election Notice, the Amortized Notes shall continue to be governed by this Section 1(d), regardless of any subsequent transfer by EarthLink of all or any portion of the Amortized Notes.

Section 2.               Method of Payment. The Company will pay interest (except defaulted interest) on the principal amount of the Notes as provided above on each March  15 and September 15, commencing September  15, 2006, to each person in whose names the Notes are registered (a “Holder”) on the March 1 or September 1 immediately preceding the Interest Payment Date, in each case, even if the Note is cancelled on registration of transfer or registration of exchange after such record date. If a payment date is a date other than a Business Day, payment may be made on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period. “Business Day” shall mean any day except Saturday, Sunday or any other day on which commercial banks in the State of California are authorized by law or other governmental action to close.

Section 3.               Limitations. The Notes are general secured obligations of each of Group and Operating, will rank pari passu in right of payment with all existing and future secured, unsubordinated indebtedness of each of Group and Operating and will be senior in right of payment to all unsecured indebtedness and subordinated indebtedness of each of Group and Operating.

Section 4.               Conversion of Note by Holder.

(a)               Subject to the further provisions of this Section 4(a), a Holder of a Note may convert such Note (or portion thereof) at any time beginning March 15, 2008, through the close of business on the Final Maturity at the Conversion Price then in effect into shares of the common stock of Group (the “Common Stock”); provided however, that in the event of a Change in Control, a Holder may convert such Note immediately prior to the Change of Control irrespective of whether conversion were to occur prior to March 15, 2008. For purposes of this Section 4, the Company shall mail notice to the Holders not less than five Business Days prior to the occurrence of any Change of Control, provided that the Company has knowledge of such Change in Control. The number of shares of Group’s Common Stock issuable upon conversion of a Note shall be determined by dividing the outstanding principal amount (excluding accrued and unpaid interest) of the Note (or portion thereof) surrendered for conversion by the Conversion Price in effect on the Conversion Date (as defined in Section 4(b)). In connection with any such conversion, such Holder also shall have the right to receive a payment (each, a “Conversion Interest Payment”), at the time and in the manner provided in Section 4(b), of the accrued and unpaid interest with respect to the outstanding principal amount of the Note (or portion thereof) so converted, which payment shall be made, at the election of the Company, in cash, Common

4

Stock, or a combination thereof. Subject to adjustment or voluntary reduction as provided in this Section 4, the Conversion Price initially shall be $1.86 per share of Group’s Common Stock.

A Holder of Notes is not entitled to any rights of a holder of Group’s Common Stock until such Holder has converted its Notes to Group’s Common Stock.

(b)              Conversion Procedure. To convert a Note, a Holder must (i) complete and manually sign the conversion notice on the back of the Note (or complete and manually sign a facsimile of such notice) and deliver such notice to the Company, (ii) surrender the Note to the Company, (iii) have satisfied any necessary filing requirements under the Hart-Scott-Rodino Act of 1976, as amended (the “HSR Act”), in respect of its acquisition of the shares of Group’s Common Stock upon such conversion and the waiting period under such HSR Act shall have expired or been terminated without objection to such acquisition, (iv) have received any other necessary regulatory consents to its acquisition of the shares of Group’s Common Stock upon such conversion and (v) pay any transfer or similar tax if required pursuant to Section 4(d) hereof. The date on which the Holder satisfies all of those requirements is the “Conversion Date.”  The notice of conversion shall state that the Holder has satisfied or will have satisfied prior to the issuance of shares of the Group’s Common Stock upon conversion of such principal amount, and prior to the payment of the Conversion Interest Payment, any and all legal or regulatory requirements for conversion, including compliance with the Securities Act, the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the HSR Act. The Company shall use its reasonable best efforts in cooperating in a timely manner with such Holder to obtain such legal or regulatory approvals to the extent its cooperation is necessary.

As soon as practicable after the Conversion Date and in no event later than five Business Days following the Conversion Date, Group shall deliver to the Holder (i) a certificate for the number of whole shares of Group’s Common Stock issuable upon the conversion of the Note or portion thereof as determined in accordance with this Section 4, (ii) cash in lieu of any fractional shares pursuant to Section 4(c) hereof and (iii) cash, Common Stock, or a combination thereof, in an amount equal to the Conversion Interest Payment.

The individual, corporation, partnership, limited liability company, joint venture, association, joint-stock company, trust or other entity organization, including a government or political subdivision or an agency or instrumentality thereof (each a “Person” or “Persons”) in whose name the certificate is registered shall be deemed to be a stockholder of record on and after the Conversion Date, as the case may be; provided that no surrender of a Note on any date when the stock transfer books of Group shall be closed shall be effective to constitute the Person or Persons entitled to receive the shares of Group’s Common Stock upon such conversion as the record holder or holders of such shares of Group’s Common Stock on such date, but such surrender shall be effective to constitute the Person or Persons entitled to receive such shares of Group’s Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; and provided further, that such conversion shall be at the Conversion Price in effect on the Conversion Date as if the stock transfer books of Group had not been closed. Upon conversion of a Note (in whole and not in part), such Person shall no longer be a Holder of such Note.

5

If any Holder surrenders a Note for conversion after the close of business on the Regular Record Date for the payment of an installment of interest and before the close of business on the related Interest Payment Date, the Company shall pay accrued interest, if any, through the Conversion Date to the Holder of such Note on such Regular Record Date.

Upon surrender of a Note that is converted in part, as soon as practicable after the Conversion Date and in no event later than five Business Days following the Conversion Date, the Company shall execute and deliver to the Holder, a new Note equal in principal amount to the unconverted portion of the Note surrendered.

If the last day on which a Note may be converted is not a Business Day, the Note may be surrendered to the Company on the next succeeding day that is a Business Day.

(c)               Fractional Shares. Group shall not issue fractional shares of its Common Stock upon conversion of any Notes. In lieu thereof, the Company shall, at the Company’s option, pay an amount in cash based upon the Current Market Price on the Business Day immediately prior to the Conversion Date or round up the number of shares of Group’s Common Stock issuable upon such conversion to the next highest whole number of shares.

(d)              Taxes on Conversion. If a Holder converts a Note, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of its Common Stock upon such conversion. However, the Holder shall pay any such tax that is due because the Holder requests the shares to be issued in a name other than the Holder’s name. Group may refuse to deliver the certificate representing the shares of Group’s Common Stock being issued in a name other than the Holder’s name until the Company receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

(e)               Adjustment of Conversion Price. The Conversion Price shall be adjusted from time to time by the Company as follows:

(i)            In case Group shall (A) pay a dividend in shares of its Common Stock to all holders of its Common Stock, (B) make a distribution in shares of its Common Stock to all holders of its Common Stock, (C) subdivide or split its outstanding Common Stock into a larger number of shares, or (D) combine its outstanding Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior thereto shall be adjusted so that the Holder of any Note thereafter surrendered for conversion shall be entitled to receive that number of shares of Group’s Common Stock that it would have owned or been entitled to receive had such Note been converted immediately prior to the happening of such event. An adjustment made pursuant to this Section 4(e)(i) shall become effective as of the close of business on the record date fixed for the determination of stockholders entitled to receive such dividend or distribution in the case of a dividend in shares or distribution in shares and shall become effective as of the close of business on the effective date in the case of a subdivision, split or combination. If any dividend or distribution of the type described in this Section 4(e)(i) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price that would then be in effect if such dividend or distribution had not been declared.

6

(ii)           In case (A) Group shall issue rights, options or warrants to all or substantially all holders of its Common Stock entitling them (for a period commencing no earlier than the record date described below and expiring not more than 60 days after such record date) to subscribe for or purchase shares of its Common Stock (or securities convertible into its Common Stock) at a price per share less than the Current Market Price at the record date fixed for the determination of stockholders entitled to receive such rights or warrants or (B) Group shall sell or issue any shares of its Common Stock and the consideration per share of Group’s Common Stock to be paid upon such sale or issuance is less than the Current Market Price or Group shall sell or issue warrants, options, rights or other convertible securities to subscribe for or purchase shares of its Common Stock at a price per share less than the Current Market Price on the date of such sale or issuance, the Conversion Price in effect immediately prior to the close of business on the record date or issue date thereto shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such record date or issue date (as the case may be) by a fraction, the numerator of which shall be the number of shares of Group’s Common Stock outstanding at the close of business on such record date or issue date (as the case may be), plus the number of shares that the aggregate offering price of the total number of shares of Group’s Common Stock so offered (or the aggregate conversion price of the convertible securities so offered) would purchase at such Current Market Price, and the denominator of which shall be the number of shares of Group’s Common Stock outstanding at the close of business on such record date or issue date (as the case may be) plus the number of additional shares of Group’s Common Stock offered (or into which the convertible securities so offered are convertible). Such adjustment shall be made successively whenever any such rights, options, warrants or convertible securities are issued, and shall become effective as of the close of business on such record date or issue date (as the case may be). To the extent that shares of Group’s Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Price shall be adjusted to the Conversion Price that would then be in effect had the reduction made upon the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Group’s Common Stock actually delivered. In the event that such rights, options or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such record date had not been fixed. In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Group’s Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Group’s Common Stock, there shall be taken into account the fair market value of any consideration received by Group for such rights, options or warrants and any amount payable on exercise or conversion thereof.

(iii)          In case Group shall, by dividend or otherwise, distribute to all holders of its Common Stock, cash, then, in such case, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the record date fixed for the determination of stockholders entitled to receive such distribution by a fraction, the numerator of which shall be Current Market Price on such record date less the amount of cash so distributed (and not excluded as provided above) applicable to one share of Group’s Common Stock and the denominator shall be the Current Market Price on such record date. Such reduction shall become effective as of the close of business on such record date; provided that, in the event the portion of the cash so distributed applicable to one share of Group’s Common Stock is equal to

7

or greater than the Current Market Price on such record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion, in addition to the shares of Group’s Common Stock issuable upon such conversion, the amount of cash such Holder would have received had such Holder converted such Note on such record date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such dividend or distribution had not been declared. If any adjustment is required to be made as set forth in this Section 4(e)(iii) as a result of a distribution that is a regular dividend, such adjustment shall be based upon the amount by which such distribution exceeds the amount of the regular cash dividend permitted to be excluded pursuant hereto. If an adjustment is required to be made as set forth in this Section 4(e)(iii) as a result of a distribution that is not a regular dividend, such adjustment shall be based upon the full amount of the distribution.

(iv)          In case Group shall distribute to all or substantially all holders of its Common Stock any of Group’s shares, interests, participations or other equivalents (however designated, whether voting or non-voting) in equity, whether outstanding on the Issue Date or issued thereafter, including all preferred stock of Group (the “Capital Stock”) (other than Group’s Common Stock), evidences of indebtedness or other non-cash assets (including securities of any Person), or shall distribute to all holders of its Common Stock rights, options or warrants to subscribe for or purchase any of its securities (excluding those referred to in Section 4(e)(ii)) (any of the foregoing hereinafter referred to as the “Distributed Securities”), then in each such case the Conversion Price in effect immediately prior to the close of business on the record date for the determination of stockholders entitled to receive such Distributed Securities shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect as of the close of business on such record date by a fraction, the numerator of which shall be the Current Market Price on such record date less the fair market value on such record date of the portion of the Distributed Securities applicable to one share of Group’s Common Stock (determined on the basis of the number of shares of Group’s Common Stock outstanding on the record date), and the denominator of which shall be the Current Market Price on such record date. Such reduction shall become effective as of the close of business on such record date; provided, that the then fair market value of the portion of the Distributable Securities so distributed applicable to one share of Group’s Common Stock is equal to or greater than the Current Market Price on such record date, in lieu of making the foregoing reduction, adequate provision shall be made so that each Holder of a Note receives at such time, or shall have the right to receive upon such conversion, in addition to the shares of Group’s Common Stock issuable upon such conversion, the amount of Distributed Securities such Holder would have received had such Holder converted such Note on such record date. In the event that such distribution is not so made, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 4(e)(iv) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price.

Rights, options or warrants distributed by Group to all holders of Group’s Common Stock entitling the holders thereof to subscribe for or purchase shares of Group’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a

8

specified event or events (each a “Trigger Event”):  (A) are deemed to be transferred with such shares of Group’s Common Stock, (B) are not immediately exercisable and (C) are also issued in respect of future issuances of Group’s Common Stock, shall be deemed not to have been distributed for purposes of this Section 4(e) (and no adjustment to the Conversion Price under this Section 4(e) shall be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Price shall be made under this Section 4(e)(iv).

If any such right, option or warrant, including any such existing right, option or warrant distributed prior to the Issue Date, is subject to events, upon the occurrence of which such right, option or warrant becomes exercisable to purchase different securities, evidences of indebtedness or other non-cash assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price under this Section 4(e) was made, (A) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Group’s Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Group’s Common Stock as of the date of such redemption or repurchase and (B) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Price shall be readjusted as if such rights, options and warrants had not been issued.

No adjustment of the Conversion Price shall be made pursuant to this Section 4(e)(iv) in respect of rights, options or warrants distributed or deemed distributed on any Trigger Event to the extent that such rights, options or warrants are actually distributed, or reserved by Group for distribution, to any Holder upon conversion by such Holder of a Note to shares of Group’s Common Stock. For purposes of this Section 4(e)(iv) and Sections 4(e)(i) and (ii), any dividend or distribution to which this Section 4(e)(iv) is applicable that also includes shares of Group’s Common Stock, or rights, options or warrants to subscribe for or purchase shares of Group’s Common Stock (or both), shall be deemed instead to be (A) a dividend or distribution of the evidences of indebtedness, non-cash assets or shares of Group’s Capital Stock other than such shares of Group’s Common Stock (and any Conversion Price reduction required by this Section 4(e)(iv) with respect to such dividend or distribution shall then be made) immediately followed by (B) a dividend or distribution of such shares of Group’s Common Stock or such rights, options or warrants (and any further Conversion Price reduction required by Sections 4(e)(i) and (ii) with respect to such dividend or distribution shall then be made), except “the record date for the determination of stockholders entitled to receive such Distributed Securities” shall be substituted as “the record date fixed for the determination of stockholders entitled to receive such dividend or distribution” and “the record date fixed for the determination of

9

stockholders entitled to receive such rights, options or warrants” within the meaning of Sections 4(e)(i) and (ii).

(v)           In case a tender or exchange offer made by Group or any subsidiary of Group for all or any portion of Group’s Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall involve the payment by Group or such subsidiary to stockholders of consideration per share of Group’s Common Stock having a fair market value (at the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended)) that exceeds the Current Market Price on the Trading Day next succeeding the Expiration Time, the Conversion Price shall be reduced so that the same shall equal the Conversion Price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction, the numerator of which shall be the number of shares of Group’s Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time multiplied by the Current Market Price on the Trading Day next succeeding the Expiration Time, and the denominator of which shall be the sum of (A) the fair market value of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to any such maximum, being referred to as the “Purchased Shares”) and (B) the product of the number of shares of Group’s Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Current Market Price on the Trading Day next succeeding the Expiration Time, such reduction to become effective immediately prior to the opening of business on the Trading Day next succeeding the Expiration Time. In the event that Group or such subsidiary is obligated to purchase shares of Group’s Common Stock pursuant to any such tender or exchange offer, but Group or such subsidiary is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price that would then be effect if such tender or exchange offer had not been made.

(vi)          The following terms shall have the meaning indicated:

“Closing Price” means, with respect to any securities on any date, the closing sale price, regular way, on such day or, in case no such sale takes place on such day, the average of the reported closing bid and asked prices, regular way, in each case on the New York Stock Exchange, or, if such security is not listed or admitted to trading on such Exchange, on the principal security exchange or automated quotation system in the United States on which such security is quoted or listed or admitted to trading, or, the average of the closing bid and asked prices of such security on the over the counter market on the day in question as reported by The Nasdaq National Market or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose.

“Current Market Price” means the average of the daily Closing Prices per share of Group’s Common Stock for the ten consecutive Trading Days immediately prior to the date in question or, if Group’s Common Stock is not listed or quoted or admitted to trading on any

10

national security exchange or automated quotation system in the United States, the fair market value of Group’s Common Stock immediately prior to the date in question.

“fair market value” means the price that would be paid in an arm’s-length transaction between an informed and willing seller under no compulsion to sell and an informed and willing buyer under no compulsion to buy, as determined in good faith by the Board of Directors; provided that with respect to any transaction or series of related transactions having a value in excess of $10 million, such determination is made by disinterested members of the Board of Directors (it being acknowledged and agreed that no such member shall be deemed interested in any such transaction by reason of the fact that such member or any of its affiliates owns or controls securities of Group).

“Trading Day” means a day on which the principal national securities exchange or automated quotation system in the United States on which Group’s Common Stock is listed or quoted or admitted to trading is open for the transaction of business or, if Group’s Common Stock is not listed or quoted or admitted to trading on any national securities exchange or automated quotation system in the United States, any Business Day.

(vii)         In any case in which this Section 4(e) shall require that an adjustment be made on a record date established for purposes of this Section 4(e), the Company may elect to defer (but only until five Business Days following the mailing by the Company to the Holders of the certificate described in Section 4(i) hereof) issuing to the Holder of any Note converted after such record date but prior to the issue date, the shares of Group’s Common Stock and other Capital Stock of Group issuable upon such conversion over and above the shares of Group’s Common Stock and other Capital Stock of Group issuable upon such conversion only on the basis of the Conversion Price prior to adjustment and, in lieu of the shares the issuance of which is so deferred, Group shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by Group of the right to receive such shares.

(viii)        If any of the following shall occur, namely:  (A) any reclassification or change of shares of Group’s Common Stock issuable upon conversion of the Notes (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination, or any other change for which an adjustment is provided in this Section 4(e)); (B) any consolidation, merger or combination to which Group is a party other than a merger in which Group is the continuing corporation and which does not result in any reclassification of, or change (other than a change in name, or in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of Group’s Common Stock; or (C) any sale, transfer or conveyance of all or substantially all of the property and assets of Group to any Person, then Group, or such successor or purchasing corporation or, if applicable, the parent entity of such successor or purchasing corporation, as the case may be, shall, as a condition precedent to such reclassification, change, consolidation, merger, combination, sale, transfer or conveyance, execute and deliver to the Holders an amendment to the Notes providing that the Holder of each Note then outstanding shall have the right to convert such Note into the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale, transfer or conveyance by a holder of the number of shares of Group’s Common Stock deliverable upon conversion of

11

such Note immediately prior to such reclassification, change, consolidation, merger, sale, transfer or conveyance.

(f)               No Adjustment. No adjustment in the Conversion Price shall be required unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price as last adjusted; provided that any adjustments which by reason of this Section 4(f) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 4 shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be. No adjustment need be made for (i) the issuance of options or rights to purchase Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by Group or any subsidiary so long as the exercise price of such options or rights is not less than the Current Market Price per share of Common Stock on such issue date, (ii) the issuance of Common Stock pursuant to and in accordance with the terms of Group’s Employee Stock Purchase Plan, or (iii) the issuance of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the Issue Date. No adjustment need be made for a change in the par value or a change to no par value of Group’s Common Stock. To the extent that the Notes become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. Notwithstanding anything to the contrary herein or in any Additional Note, in no event shall the conversion of this Note and any Additional Notes (as defined in this Note and in the Registration Rights Agreement of even date herewith between Group and EarthLink), taking into account all prior conversions, be converted in an aggregate number of shares of Common Stock which in the aggregate exceeds 19.9% of the then outstanding shares of Common Stock.

(g)              Adjustment for Tax Purposes.

Such assignment shall be effective upon acceptance by such Holder and such Holder shall become the “Collateral Agent” for all purposes under this Note and the Security Agreement.
