          Business, except for Licenses the failure of which to obtain would not
          be reasonably expected to have a Material Adverse Effect. Except as
          set forth on Schedule 6.4, all Covad Licenses are currently in full
          force and effect and there are no pending or, to the Knowledge of
          Covad, threatened revocation proceedings which would have a Material

          occurred which, with or without the giving of notice or the lapse of

          cancellation or nonrenewal of any of the Covad


                                       14







<PAGE>

          Governmental Authority, nor, to the Knowledge of Covad, is there any

     SBC will use commercially reasonable efforts and cooperate with Covad to
     secure promptly all necessary Consents and to prepare and file promptly all
     notifications under the HSR Act in connection with this Agreement and to
     respond as promptly as practicable to any inquiries received from the
     Federal Trade Commission and the Antitrust Division of the Department of

<PAGE>


     shall not be unreasonably withheld, and SBC shall furnish to Covad advance
     copies of any release which it proposes to make public concerning this
     Agreement or the transactions contemplated by this Agreement and the date
     upon which SBC proposes to make such press release. This provision shall
     not, however, be construed to prohibit SBC from making any disclosures to
     any Governmental Authority or other Person which it is required to make
     under any Legal Requirement or to obtain any Consents.

7.4  LOCK-UP PERIOD.

     Notwithstanding anything to the contrary in this Agreement, for a period of
     one year from the Closing Date, SBC shall not, without Covad's prior
     written consent, directly or indirectly, sell, pledge, contract to sell,
     transfer or otherwise dispose of any of the Shares or any interest therein,
     unless there has been a Covad Change in Control Event. Any attempted sale,
     pledge, transfer or other disposition by SBC which is not in compliance
     with this Section 7.4 shall be null and void.

7.5  FURTHER ASSURANCES.

     At any time or from time to time after the Closing Date, SBC shall execute
     and deliver any further instruments or documents, and take all such further
     action as Covad may reasonably request, in order to effect this Agreement
     and issue and deliver the Shares to SBC free and clear of all Liens.

7.6  RIGHTS OF FIRST OFFER AND REFUSAL.

     7.6.1 Prior to any sale, transfer or other disposition of Shares (a
          "Sale"), SBC shall first give written notice (a "First Offer Notice")
          to Covad stating the intention of SBC to cause such a Sale, the name
          and address of the proposed transferee, if any, the consideration
          which SBC propose to have paid by a transferee (the "First Offer
          Price") and the other material terms upon which such Sale is proposed.
          If the consideration specified in the First Offer Notice is other than
          cash, the First Offer Price shall be the fair market value of the
          non-cash consideration.

     7.6.2 Upon receipt of the First Offer Notice, Covad shall have an
          irrevocable non-transferable option (the "First Offer") to purchase
          the Shares that are the subject of the First Offer Notice at the First
          Offer Price in cash and upon the same terms and conditions as those
          proposed by SBC. The First Offer Notice shall specify that the closing
          of the purchase by Covad shall occur not later than ten (10) Business
          Days after the offer is accepted (or, if any Consents are required,
          the later of ten (10) Business Days after the offer is accepted and
          five (5) Business Days after the receipt of any such Consents). Covad
          shall have ten (10) Business Days to accept or reject the First Offer.
          If Covad accepts the First Offer, Covad shall send written notice of
          such acceptance to SBC (the "Acceptance Notice") and shall be
          obligated to purchase the Shares subject to the First Offer on the
          terms and conditions set forth in the First Offer Notice.


                                       19







<PAGE>


     7.6.3 Upon exercise by Covad of its right of First Offer, Covad and SBC
          shall be legally obligated to consummate the purchase contemplated
          thereby and shall use their reasonable commercial efforts to secure
          any Government Approvals required, to comply as soon as reasonably
          practicable with all Applicable Law and to take all such other actions
          and to execute such additional documents as are reasonably necessary
          or appropriate in connection therewith.

     7.6.4 If the First Offer is not accepted, or if Covad has exercised its
          right of First Offer but the transaction fails to close, then SBC
          shall be free, for a period of one hundred twenty (120) days from the
          earlier of (i) the expiration of the acceptance period with respect to
          such First Offer pursuant to Section 7.6.2 of this Agreement and (ii)
          the date SBC shall have received written notice from Covad stating
          that Covad does not intend to accept the First Offer to sell the
          Shares subject to the First Offer to one or more third parties for
          consideration equal to or greater than the First Offer Price on no
          more favorable terms to the third party than were contained in the
          First Offer Notice.

     7.6.5 If the third party to whom SBC proposes to sell the Shares is a
          Significant Competitor of Covad, SBC shall give written notice (a
          "First Refusal Notice") to Covad stating the intention of SBC to cause
          such a Sale, the name and address of the proposed transferee, the
          consideration which SBC propose to have paid by a transferee (the
          "First Refusal Price") and the other material terms upon which such
          Sale is proposed. If the consideration specified in the First Refusal
          Notice is other than cash, then the First Refusal Price shall be the
          fair market value of the non-cash consideration. SBC shall comply with
          Sections 7.6.5 to 7.6.8 of this Agreement even if SBC already has
          complied with Sections 7.6.1 to 7.6.4 of this Agreement with respect
          to the same Shares.

     7.6.6 Upon receipt of the First Refusal Notice, Covad shall have an
          irrevocable non-transferable option (the "First Refusal") to purchase
          the Shares that are the subject of the First Refusal Notice at the
          First Refusal Price in cash and upon the same terms and conditions as
          those proposed by SBC. The First Refusal Notice shall specify that the
          closing of the purchase shall occur not later than ten (10) Business
          Days after the offer is accepted (or, if any Government Approvals are
          required, the later of ten (10) Business Days after the offer is
          accepted and five (5) Business Days after the receipt of any such
          Government Approvals). Covad shall have ten (10) Business Days to
          accept or reject the First Refusal. If Covad accepts the First
          Refusal, Covad shall send written notice of such acceptance to SBC and
          shall be obligated to purchase the Shares subject to the First Refusal
          on the terms and conditions set forth in the First Refusal Notice.

     7.6.7 Upon exercise by Covad of its right of First Refusal, Covad and SBC
          shall be legally obligated to consummate the purchase contemplated
          thereby and shall use their reasonable commercial efforts to secure
          any Government Approvals required, to comply as soon as reasonably
          practicable with all Applicable Law and to take all such other actions
          and to execute such additional documents as are


                                       20







<PAGE>


          reasonably necessary or appropriate in connection therewith.

     7.6.8 If the First Refusal is not accepted, then SBC shall be free, for a
          period of sixty (60) days from the earlier of (i) the expiration of
          the acceptance period with respect to such First Refusal pursuant to
          Section 7.6.6 of this Agreement and (ii) the date SBC shall have
          received written notice from Covad stating that Covad does not intend
          to accept the First Refusal to sell the Shares to the third party
          identified in the First Refusal Notice for the First Refusal Price.

7.7  BOARD OF DIRECTORS.

     7.7.1 From and after the date of this Agreement and until the fifth
          anniversary of the Closing Date, SBC will vote, or cause to be voted
          (or grant consents to vote in any action to be taken by written
          consent), the Shares and any other shares of Common Stock that SBC or
          its Affiliates may acquire or Beneficially Own (collectively, the
          Shares and any such other shares shall be referred to as the "SBC
          Shares") for nominees to Covad's Board of Directors either (i) as
          recommended by Covad's Board of Directors or (ii) in proportion to the
          votes cast by other holders of Voting Securities of Covad, at SBC's
          choice.

     7.7.2 SBC agrees that all SBC Shares will be represented, in person or by
          proxy, at all meetings of holders of Voting Securities of which SBC
          has actual notice, so that all SBC Shares may be counted for the
          purpose of determining the presence of a quorum at such meetings (it
          being acknowledged that even if SBC has chosen to vote in proportion
          to the votes cast by other holders of Voting Securities of Covad with
          respect to the election of directors, all SBC Shares (as opposed to
          simply a portion of the SBC Shares corresponding to the proportion of
          the other shares of Common Stock represented in such vote) will be
          voted with respect to the election of directors in proportion to votes
          cast by the other holders of Voting Securities). Whenever stockholders
          act by written consent with respect to the election of directors, if
          SBC chooses to act in proportion to the consents of other stockholders
          it shall consent to such action with respect to a percentage of the
          SBC Shares equal to the percentage of outstanding shares other than
          SBC Shares that consent to such action.

     7.7.3 SBC hereby revokes any and all previous proxies granted with respect
          to the SBC Shares that are inconsistent with the voting agreement set
          forth in this Section 7.7. By entering into this Agreement, SBC hereby
          grants a proxy appointing Robert E. Knowling, Jr. (or if he ceases to
          be Chief Executive Officer of Covad, the person holding the office of
          Chief Executive Officer of Covad from time to time) as SBC's
          attorney-in-fact and proxy, with full power of substitution, for and
          in SBC's name, to be represented at meetings of holders of Voting
          Securities and to vote or consent or otherwise to utilize such voting
          power solely in the manner contemplated by this Section 7.7. The proxy
          granted by SBC pursuant to this Section 7.7.3 is irrevocable until the
          fifth anniversary of the Closing Date, except in the case of a Sale,
          and is coupled with an interest and is granted in


                                       21







<PAGE>


          consideration of Covad entering into this Agreement and consummating
          the Closing under this Agreement and as security for the obligations
          of SBC herein.

     7.7.4 If SBC is not the record owner of any SBC Shares as to which it or
          any of its Affiliates is the Beneficial Owner, SBC agrees to cause or
          direct the record holder to act in respect of such SBC Shares in
          accordance with the terms of this Agreement or, to the extent
          permitted by law, to provide a proxy to Covad with respect thereto.

     7.7.5 SBC hereby covenants and agrees that it shall not, nor shall it
          permit its Affiliates to, enter into any voting agreement or grant a
          proxy or power of attorney or take any other action with respect to
          the SBC Shares which is inconsistent with this Agreement.

     7.7.6 SBC hereby covenants and agrees that SBC will not, nor shall it
          permit its Affiliates to, sell, transfer, pledge or otherwise dispose
          of any of the SBC Shares or any interest therein to a Significant
          Competitor unless (i) such sale, transfer, pledge or disposition is
          permitted under this Agreement and (ii) such sale, transfer, pledge or
          disposition is to a Significant Competitor (other than a Significant
          Competitor who, without prearranging such purchase with SBC or its
          Affiliates, purchases SBC Shares in the public markets pursuant to and
          in compliance with the restrictions of Section 7.8) that agrees in
          writing to be bound by the terms and conditions of this Agreement on
          terms satisfactory to Covad in its reasonable discretion.

     7.7.7 SBC will execute and deliver, or cause to be executed and delivered,
          all further documents and instruments and use all reasonable efforts
          to take, or cause to be taken, all actions and to do, or cause to be
          done, all things necessary, proper or advisable to take the actions
          required to be taken by SBC under this Agreement. SBC agrees, at the
          request of Covad, to enter into such other arrangement, agreement or
          proxy with respect to the voting of the SBC Shares to effect the
          intent of this Section 7.7.

7.8  DISPOSITION.

     SBC shall seek to effect any transfer of Shares (other than through a
     private resale in a transaction exempt from the registration requirements
     of the Securities Act) in a manner that will avoid material harm to the
     market price of the Common Stock. SBC and Covad shall negotiate in good
     faith reasonable restrictions, including volume limitations, on such
     transfers to seek to avoid material harm to the market price of the Common
     Stock.

     to the voting thereof, (f) form, join or participate in a "group" (as
     defined in the Securities Exchange Act) with respect to Covad with respect
     to the matters set forth in (a) to (h), (g) seek or cause any other Person
     to seek representation on the Covad Board of Directors or seek or cause
     other Persons to seek the removal of any member of the Covad Board of
     Directors, or (h) take any action which would reasonably be expected to
     force Covad to make a public announcement regarding any of the types of
     matters set forth in (a) to (c) above; provided, however, that nothing this
     Section 7.9 shall be construed to prohibit SBC from discussing, with
     Covad's consent, any of the matters set forth in (a) to (e) or (g) with
     Covad, its Subsidiaries and their representatives so long as such
     discussions are not proposed or disclosed by SBC or its Affiliates in a
     public manner or conducted in a manner which would reasonably be expected
     to force Covad to make a public announcement of such discussions or
     proposal; provided, further, that once a Person (without the participation
     or assistance of SBC or its Affiliates) initiates or proposes to initiate
     matters set forth in (b), (c), (d) or (g) which, if consummated, would
     constitute a Covad Change in Control Event, SBC shall have no further
     obligations under this Section 7.9 unless such a matter set forth in such
     clauses is not consummated, in which case this Section 7.9 shall become
     applicable for the remainder of the period until the fifth anniversary of
     the Closing Date.

                                  ARTICLE VIII

     auditors to furnish to SBC such financial and other data and information

     make public concerning this Agreement or the transactions contemplated by
     this Agreement and the date upon which Covad proposes to make such press

     from making any disclosures to any Governmental Authority or other Person
     which it is required to make under any Legal Requirement, or to obtain any
     Consents or from making any public disclosures as may be required to comply
     with Applicable Law or the rules and regulations of any stock exchange or

8.6  REGISTRATION RIGHTS.

     8.6.1 (a) At any time in the five (5) years after the Permitted
               Registration Date, any Holder or Holders holding, in the
               aggregate, at least 51 percent of the Shares eligible for
               registration pursuant to Section 8.6.7 of this Agreement shall
               have the right, on one occasion only, by written request of one
               or more Holders (the "Selling Shareholders") to Covad, to require
               Covad to prepare a registration statement (the "Registration
               Statement") on the appropriate form under the Securities Act with
               respect to some or all of the Shares then owned by such Selling
               Shareholders.

          (b)  If the Selling Shareholders so elect, the offering of such Shares
               pursuant to such Registration Statement shall be in the form of
               an underwritten offering. A majority in interest of the Selling
               Shareholders shall have the right to select the managing
               underwriters and any additional investment bankers and managers
               to be used in connection with such offering, subject to Covad's
               approval, which approval shall not be unreasonably withheld.

          (c)  The Selling Shareholders will inform Covad of the time and manner
               of any disposition of Shares, and agree to reasonably cooperate
               with Covad in effecting the disposition of the Shares in a manner
               that does not unreasonably disrupt the public trading market for
               the Common Stock.

          (d)  Covad will have the right to preempt any Registration Statement
               with a primary registration by delivering written notice (within
               ten (10) business days after Covad has received a request for
               such Registration Statement) of such intention to SBC indicating
               that Covad intends to file a registration statement with respect
               to such a primary registration within 90 days of such notice and
               complete the sale as soon as practicable thereafter. In the
               ensuing primary registration, the Holders will have such
               piggyback registration rights as are set forth in Section 8.6.2
               of this Agreement. Upon Covad's preemption of a requested
               Registration Statement, such requested registration will not
               count as the one demand registration pursuant to this Section
               8.6.1; PROVIDED that the demand registration will not be deemed
               preempted if the Holders are permitted to sell all requested
               securities in connection with the ensuing primary offering by
               exercising their piggyback registration rights as set forth in
               Section 8.6.2 of this Agreement. Covad may exercise the right to
               preempt only twice in any 360-day period; PROVIDED, that
               notwithstanding this Section 8.6.1(d) or Section 8.6.4(a) of this
               Agreement during any 360-day period there shall be at least two
               periods of at least 90 consecutive days during which the Selling
               Shareholders may effect a demand registration under this Section
               8.6.1.

     8.6.2 If, at any time in the five (5) years after the Permitted
          Registration Date, Covad shall propose to prepare on its own behalf or
          on behalf of any holders of any of its


                                       25







<PAGE>


          Common Stock a registration statement in connection with an
          underwritten public offering of any shares of such Common Stock (other
          than a registration statement on Form S-4 or S-8 or such other form as
          shall be prescribed under the Securities Act for the same purposes),
          then Covad shall give each Holder written notice at least twenty (20)
          or, in case of a registration statement proposed to be filed pursuant
          to Rule 415 of the Securities Act (other than a registration statement
          covering shares issued in acquisitions pursuant to Section 4(2) under
          the Securities Act or covering shares pursuant to the exercise of
          demand registration rights of other holders of securities of Covad),
          ten (10) Business Days before the anticipated filing date of such
          registration statement. Should any Holder desire to have any Shares
          included in such registration statement, such Holder shall so notify
          Covad in writing no later than ten (10) or, in the case of a
          registration statement proposed to be filed pursuant to Rule 415 of
          the Securities Act, five (5) Business Days after Covad's notice is
          given, setting forth the number of Shares which such Holder requests
          to be included in the registration statement and providing any other
          information requested by Covad in its original notice relating to
          inclusion in the registration statement. Any such registration
          statement that includes Shares is hereinafter included in the term
          "Registration Statement," and each Holder who owns Shares included in
          a Registration Statement shall be a Selling Shareholder with respect
          to such Registration Statement. If Covad shall determine in its sole
          discretion not to register or to delay the proposed offering, Covad
          may, at its election, provide written notice of such determination to
          the Holders and (i) in the case of a determination not to effect the
          proposed offering, shall thereupon be relieved of the obligation to
          register such Shares in connection therewith, and (ii) in the case of
          a determination to delay a proposed offering, shall thereupon be
          permitted to delay registering such Shares for the same period as the
          delay in respect of the proposed offering. As between Covad and the
          Selling Shareholders, Covad shall be entitled to select the
          underwriters in connection with any piggyback registration under this
          Section 8.6.2. The Holders' exercise of their piggyback registration
          rights under this Section 8.6.2 shall not extinguish their demand
          registration rights under Section 8.1.1(a) of this Agreement.

     8.6.3 In connection with a Holder's request for registration of Shares
          pursuant to Section 8.6.2 of this Agreement, Covad may refuse to
          include Shares in a registration statement if in Covad's reasonable
          judgment, based on the advice of its investment banker, inclusion of
          such Shares would have a material adverse effect on Covad's ability to
          complete such underwritten public offering or on the price, timing or
          distribution of the offering (a "Cutback"). In the event of a Cutback,
          Covad will include in such registration statement, to the extent of
          the number which Covad is so advised can be sold in such offering
          without having a material adverse effect on the ability of Covad to
          complete such offering or on the price, timing or distribution of the
          offering, first, shares of Common Stock requested to be included in
          such registration by shareholders exercising demand registration
          rights, second securities Covad proposes to sell for its own account,


                                       26







<PAGE>


          and, subject to the rights existing as of the date of this Agreement
          of holders of registration rights with respect to securities of Covad,
          third Shares and fourth other securities of Covad included in such
          registration by the holders thereof. Prior to any Cutback, Covad shall
          provide to the Holders that have requested that Shares be included in
          the registration statement pursuant to Section 8.6.2 of this Agreement
          a letter from Covad's investment banker explaining why inclusion of
          such Shares would have a material adverse effect on Covad's ability to
          complete such underwritten public offering. If the Holders' investment
          banker believes that the Shares can be included in the registration
          statement without having a material adverse effect on Covad's ability
          to complete such underwritten public offering, Covad's investment
          banker and the Holders' investment banker shall within ten (10) days
          appoint a third investment banker who shall determine within ten (10)
          days whether such Shares can be included in the registration statement
          without having a material adverse effect on Covad's ability to
          complete such underwritten public offering.

     8.6.4 With respect to any Registration Statement under this Section 8.6 of
          this Agreement, Covad will:

          (a)  prepare and file with the SEC the Registration Statement within
               120 days after a Selling Shareholder's notice requesting
               registration or inclusion in a proposed registration, and use its
               reasonable efforts to cause the securities covered by such
               Registration Statement to become registered and such Registration
               Statement to be declared effective as expeditiously as possible
               under the Securities Act or other applicable federal law and
               regulations (and cause to be prepared and file any amendments or
               supplements thereto as may be necessary to comply with applicable
               federal law and regulations); PROVIDED, that if Covad shall
               furnish to SBC a certificate signed by Covad's Chairman,
               President or any Vice-President stating that in his or her good
               faith judgment it would be materially detrimental or otherwise
               materially disadvantageous to Covad or its stockholders for any
               Registration Statement under this Section 8.6 to be filed
               (because, for example, the sale of Shares covered by such
               Registration Statement or the disclosure of information in any
               related prospectus or prospectus supplement would materially
               interfere with any acquisition, financing or other material event
               or transaction which is then prejudicial to Covad), Covad may
               postpone the filing or postpone or suspend the effectiveness of a
               Registration Statement for a period of not more than 120 days;
               PROVIDED, that notwithstanding this Section 8.6.4(a) or Section
               8.6.1(d) of this Agreement during any 360-day period there shall
               be two periods of at least 90 consecutive days during which Covad
               will make the Registration Statement available for Holders; and
               PROVIDED FURTHER, that if (i) the effective date of any
               Registration Statement filed pursuant to Section 8.6.1 of this
               Agreement would otherwise be at least 45 calendar days, but fewer
               than 90 calendar days, after the end of Covad's fiscal year, and
               (ii) the Securities Act requires Covad to include audited

                                       27







<PAGE>


               financials as to the end of such fiscal year, Covad may delay the
               effectiveness of such registration statement for such period as
               is reasonably necessary to include therein its audited financial
               statements for such fiscal year;

          (b)  use its reasonable efforts to cause to be registered or qualified
               the securities covered by such Registration Statement under such
               securities or Blue Sky laws in such jurisdictions within the
               United States as any Selling Shareholder may reasonably request;
               provided, however, that Covad reserves the right, in its sole
               discretion, not to cause to be registered or qualified such
               securities in any jurisdiction where Covad would be required in
               connection therewith to execute a general consent to service or
               to qualify as a foreign corporation or to subject itself to
               taxation;

          (c)  maintain the effectiveness of any Registration Statement for a
               period of at least 30 days;

          (d)  promptly notify each Selling Shareholder of the happening of any
               event as a result of which any preliminary or final prospectus or
               prospectuses included in any Registration Statement includes an
               untrue statement of a material fact or omits to state any
               material fact required to be stated therein or necessary to make
               the statements not misleading in light of the circumstances then
               existing;

          (e)  furnish, at the request of any underwriter or other third party,
               an opinion, dated the date the Registration Statement became
               effective, of counsel representing Covad (which may be in-house
               counsel) for the purposes of such registration, addressed to the
               underwriter or third party and to such Selling Shareholder as to
               such customary legal matters as such underwriter or third party
               shall reasonably request; and

          (f)  furnish, at the request of any underwriter or other third party,
               a letter, dated the date the Registration Statement became
               effective, of independent certified public accountants of Covad,
               addressed to the underwriter or other third party and to such
               Selling Shareholder as to such customary accounting matters as
               such Selling Shareholder shall reasonably request.

     8.6.5 The obligations of Covad to cause a Registration Statement to be
          prepared pursuant to the provisions of this Section 8.6 and each
          Selling Shareholder's right to have shares of Common Stock included in
          any Registration Statement pursuant to the provisions of this Section
          8.6 shall be subject to the following conditions:

          (a)  Each Selling Shareholder shall furnish to Covad in writing such
               information and documents as, in the opinion of Covad's counsel,
               may be reasonably required to properly cause to be prepared such
               Registration Statement in accordance with applicable provisions
               of the Securities Act


                                       28







<PAGE>


               and the SEC's regulations thereunder or federal or state
               securities or Blue Sky laws and regulations then in effect;

          (b)  If a Selling Shareholder desires to sell and distribute Shares
               over a period of time, or from time to time, pursuant to a
               Registration Statement prepared pursuant to the provisions of
               this Section 8.6, then such Selling Shareholder shall execute and
               deliver to Covad such written undertakings as Covad and its
               counsel may reasonably require in order to assure full compliance
               with the relevant provisions of the Securities Act and the SEC's
               regulations thereunder or other federal or state securities or
               Blue Sky laws and regulations as then in effect; and

          (c)  Upon receipt of any notice from Covad of the occurrence of any
               event of the kind described in Section 8.6.4(d) of this
               Agreement, the Selling Shareholders will forthwith discontinue
               the offer and sale of Shares pursuant to the Registration
               Statement covering such Shares until receipt by the Selling
               Shareholders and any underwriters of the offering of a notice
               from the Company that the use of the Registration Statement may
               be resumed and, if applicable, such persons have received copies
               of any supplemented or amended prospectus and, if so directed by
               Covad, the Selling Shareholders will deliver to Covad all copies,
               other than permanent file copies then in the possession of
               Selling Shareholders, of the most recent prospectus covering such
               Shares at the time of receipt of such notice. In the event Covad
               shall give such notice described in Section 8.6.4(d) of this
               Agreement and such Registration Statement is already effective,
               Covad shall extend the period during which such Registration
               Statement shall be maintained effective as provided in Section
               8.6.4(c) of this Agreement by the number of days during the
               period from and including the date of the delivering of such
               certificate or giving of such notice to the date when Covad shall
               notify the Selling Shareholders that sales under the Registration
               Statement may be resumed and make available to the Selling
               Shareholders any such supplemented or amended prospectus.

     8.6.6 The Selling Shareholder will pay or cause to be paid all fees and
          expenses (including all Blue Sky and National Association of
          Securities Dealers, Inc. filing and registration fees, accounting fees
          and disbursements, printing costs, attorneys' fees and disbursements)
          arising out of the preparation, filing, amending and supplementing of
          a Registration Statement pursuant to Section 8.6.1 of this Agreement
          in which only the Selling Shareholder participates, or a proportionate
          portion thereof if Covad or other holders participate in such
          Registration Statement filed pursuant to Section 8.6.1 of this
          Agreement. Covad shall pay all fees and expenses (including all Blue
          Sky and National Association of Securities Dealers, Inc. filing and
          registration fees, accounting fees and disbursements, printing costs,
          attorneys' fees and disbursements) arising out of the preparation,
          filing, amending and supplementing of a Registration Statement
          pursuant to


                                       29







<PAGE>


          Section 8.6.2 of this Agreement. Notwithstanding the foregoing, the
          Selling Shareholders shall pay (i) any underwriting fees, discounts or
          commissions attributable to the sale of the Shares, (ii) fees and
          expenses of counsel for the Selling Shareholders and (iii) any
          out-of-pocket expenses of the Selling Shareholders.

     8.6.7 Particular shares shall no longer be eligible for registration under
          this Section 8.6 as soon as they (i) have been sold or otherwise
          disposed of pursuant to a registration statement that was filed with
          the SEC and declared effective under the Securities Act, (ii) have
          been sold or otherwise disposed of pursuant to Rule 144 under the
          Securities Act, or (iii) have been otherwise sold, transferred or
          disposed of by a Holder to any Person that is not a Holder.

     8.6.8 Notwithstanding anything in this Section 8.6 to the contrary, the
          registration rights granted by Covad to SBC and the obligations of
          Covad under this Section 8.6 shall be subject to, and, to the extent
          inconsistent with, shall be deemed modified to the minimum extent
          necessary so as not to be inconsistent with, any registration rights
          of holders of Covad securities in existence as of the date of this
          Agreement.

8.7  LISTING.

     Upon SBC's request, Covad will use its best efforts, and diligently take
     all steps necessary, to list the Shares for trading on the Nasdaq or any
     other securities exchange on which the Common Stock is traded.

8.8  FURTHER ASSURANCES.

     At any time or from time to time after the Closing Date, Covad shall
     execute and deliver any further instruments or documents, and take all such
     further action as SBC may reasonably request, in order to effect this
     Agreement and to issue to SBC the Shares free and clear of all Liens,
     except for Liens as SBC may cause to attach to the Shares.

                                   ARTICLE IX

                                   TERMINATION

9.1  TERMINATING EVENTS.

     This Agreement may be terminated prior to Closing:

     9.1.1 By the mutual written consent of Covad and SBC; or

     9.1.2 By Covad, by ten (10) Business Days written notice to SBC (if Covad
          is not then materially in default or breach of this Agreement), if SBC
          shall default in any material respect in the performance of any of its
          obligations under this Agreement


                                       30






<PAGE>


          or the Ancillary Agreements, and such default or breach has not been
          cured by SBC within seven (7) Business Days following receipt of
          written notice from Covad of Covad's intention to terminate this
          Agreement; or

     9.1.3 By SBC, by ten (10) Business Days written notice to Covad (if SBC is
          not then materially in default or breach of this Agreement), if Covad
          shall default in any material respect in the performance of any of its
          obligations under this Agreement or the Ancillary Agreements, and such
          default or breach has not been cured by Covad within seven (7)
          Business Days following receipt of written notice from SBC of SBC's
          intention to terminate this Agreement; or

     9.1.4 By either SBC or Covad if the Closing has not occurred on or before
          December 31, 2000, provided that such date shall be extended in
          monthly increments (but not beyond February 28, 2001) at the election
          of either party if the conditions specified in Sections 3.1 and 4.1 of
          this Agreement are the only conditions that would not be satisfied if
          the Closing were to occur on the date such election is made (provided
          further that the right to terminate this Agreement under this Section
          9.1.4 shall not be available to any Party whose breach of any
          obligation under this Agreement has been a cause of or resulted in the
          failure of the Closing to occur on or before such date); or

     9.1.5 By either SBC or Covad, in the event that SBC or Covad receives a
          final and nonappealable written statement from any Governmental
          Authority that states that such Governmental Authority has disapproved
          or will not give approval to this Agreement, which disapproval would
          cause the Parties to be unable to consummate the transactions
          contemplated by this Agreement or would make a condition to the
          terminating Party's obligation to consummate this transaction
          impossible to satisfy; PROVIDED, that no Party may terminate this
          Agreement pursuant to the terms of this Section 9.1.5 if such Party is
          in material breach of this Agreement.

9.2  EFFECT ON OBLIGATIONS. In the event of any termination of this Agreement
     pursuant to Section 9.1.1, 9.1.4 or 9.1.5 of this Agreement, neither SBC
     nor Covad shall have any further liability under this Agreement, except
     with respect to the confidentiality provisions of this Agreement. In the
     event of a termination under Section 9.1.2 or 9.1.3 of this Agreement, both
     Parties shall retain all their rights at law or in equity.

                                 INDEMNIFICATION

10.1 INDEMNIFICATION BY COVAD.

     10.1.1 Covad hereby agrees to indemnify SBC and its Affiliates and their
          respective officers and directors against and hold them harmless from
          any Losses suffered or


                                       31







<PAGE>


          incurred by any such Indemnified Party for or on account of or arising
          from or in connection with any breach of any representation, warranty
          or covenant of Covad contained in this Agreement, without regard to
          any materiality qualifiers contained therein, provided, however, that
          Covad shall not have any liability under this Section 10.1 unless the
          aggregate of all Losses relating thereto exceed on a cumulative basis
          Six Million Dollars ($6,000,000). Covad's maximum liability under this
          Section 10.1.1 shall not exceed One Hundred Fifty Million Dollars
          ($150,000,000).

     10.1.2 Covad agrees to indemnify and hold harmless each Selling Shareholder
          and each Person, if any, who controls (within the meaning of Section
          15 of the Securities Act and Section 20 of the Securities Exchange
          Act) such Selling Shareholder (a "Control Person") against any Losses
          to which such Selling Shareholder or any such Control Person may
          become subject, insofar as such Losses arise out of or are based upon
          any untrue statement or alleged untrue statement of any material fact
          contained in any preliminary or final Registration Statement prepared
          pursuant to Section 8.6 of this Agreement or prospectus with respect
          thereto, or any amendment or supplement thereto, or arise out of or
          are based upon the omission or alleged omission to state therein a
          material fact required to be stated therein or necessary to make the
          statements therein not misleading; provided, however, that Covad will
          not be liable in any case (i) to the extent that any such Losses arise
          out of or are based upon an untrue statement or alleged untrue
          statement or omission or alleged omission from any of such documents
          in reliance upon and in conformity with written information furnished
          by or on behalf of such Selling Shareholder or any such Control Person
          specifically for use in the preparation thereof, or (ii) insofar as
          Covad has notified such Holder of a suspension period, as described in
          Section 8.6.5(c) of this Agreement, and the Holder has sold Shares
          notwithstanding receipt of such notice; PROVIDED, HOWEVER, that Covad
          shall not be liable in any such case to the extent that any such loss,
          claim, damage, liability or expense arises out of or is based upon an
          untrue statement or alleged untrue statement or omission or alleged
          omission in the Registration Statement, the prospectus included
          therein, or any document incorporated therein by reference (the
          "Prospectus"), if such untrue statement or alleged untrue statement,
          omission or alleged omission is corrected in an amendment or
          supplement to the Prospectus and if, having previously been furnished
          by or on behalf of Covad with copies of the Prospectus as so amended
          or supplemented it required to be delivered, such Holder thereafter
          fails to deliver such Prospectus as so amended or supplemented, prior
          to or concurrently with the sale of a Prospectus to the Person
          asserting such loss, claim, damage, liability or expense who purchased
          such Prospectus which is the subject thereof from such Holder.

10.2 INDEMNIFICATION BY SBC.

     10.2.1 SBC hereby agrees to indemnify Covad and its Affiliates and their
          respective officers and directors against and hold them harmless from
          any Losses suffered or


                                       32





<PAGE>


          incurred by any such Indemnified Party for or on account of or arising
          from or in connection with any breach of any representation, warranty
          or covenant of SBC contained in this Agreement, without regard to any
          materiality qualifiers contained therein, provided, however, that SBC
          shall not have any liability under this Section 10.2 unless the
          aggregate of all Losses relating thereto exceed on a cumulative basis
          Six Million Dollars ($6,000,000) (but such limitation shall not apply
          to Losses suffered or incurred for or on account of any breach of
          SBC's obligation under this Agreement to pay the Purchase Price).
          SBC's maximum liability under this Section 10.2.1 shall not exceed One
          Hundred Fifty Million Dollars ($150,000,000).

     10.2.2 SBC and any other Selling Shareholder to whom SBC's rights under
          this Agreement have been transferred will, severally and not jointly,
          indemnify and hold harmless Covad and each of its directors, officers
          and each Person, if any, who controls (within the meaning of Section
          15 of the Securities Act and Section 20 of the Securities Exchange
          Act) Covad (a "Company Control Person") to the same extent as set
          forth in the foregoing indemnity from Covad to each Selling
          Shareholder set forth in Section 10.1.2 of this Agreement, but only
          with reference to written information included in any preliminary or
          final Registration Statement prepared pursuant to Section 8.6 of this
          Agreement or prospectus with respect thereto, or amendment or
          supplement thereto, furnished by or on behalf of such Selling
          Shareholder specifically for use in the preparation of such documents.

10.3 LOSSES.

     The amount of any Losses for which indemnification is provided under this
     Article X shall be net of any amounts recovered or recoverable by the
     Indemnified Party under insurance policies with respect to such Losses and
     shall be increased to take account of any Tax cost to the Indemnified Party
     and reduced to take account of any Tax benefit to the Indemnified Party
     arising from the incurrence or payment of any Losses.

10.4 SURVIVAL.

     The representations and warranties made by Covad contained in Article VI of
     this Agreement, and the obligation of Covad to indemnify SBC pursuant to
     Section 10.1 of this Agreement, shall survive the execution and delivery of
     this Agreement, any examination or due diligence inquiry by SBC and the
     Closing until the date which is 18 months after the Closing Date, except
     that the representations and warranties made by Covad in Section 6.8 of
     this Agreement (Title to Shares; Absence of Liens) shall survive for the
     applicable statute of limitations. The representations and warranties made
     by SBC contained in Article V of this Agreement, and the obligation of SBC
     to indemnify SBC pursuant to Section 10.2 of this Agreement, shall survive
     the execution and delivery of this Agreement, any examination or due
     diligence inquiry by Covad and the Closing until the date which is 18
     months after the Closing Date. The obligations to indemnify and hold
     harmless a Party, pursuant to Section 10.1 and Section 10.2 of this
     Agreement, shall


                                       33







<PAGE>


     survive only until the expiration of the applicable survival period for the
     representation and warranty or covenant under which the claim for
     indemnification is being made; provided, however, that such obligations to
     indemnify and hold harmless shall not terminate with respect to any item as
     to which the Person to be indemnified shall have, before the expiration of
     the applicable period, previously made a claim by delivering a notice
     (stating in reasonable detail the basis of such claim) to the Party to be
     providing the indemnification.

10.5 PROCEDURES RELATING TO THIRD PARTY CLAIMS

     10.5.1 In order for a party (the "Indemnified Party") to be entitled to any
          indemnification provided for under this Agreement in respect of,
          arising out of or involving a claim or demand made by any Person
          against the Indemnified Party (a "Third Party Claim"), such
          Indemnified Party must notify the indemnifying party in writing of the
          Third Party Claim within ten (10) Business Days after receipt by such
          Indemnified Party of written notice of the Third Party Claim;
          provided, however, that failure to give such notification shall not
          affect the indemnification provided under this Agreement except to the
          extent the indemnifying party shall have been actually prejudiced as a
          result of such failure (except that the indemnifying party shall not
          be liable for any expenses incurred during the period in which the
          Indemnified Party failed to give such notice). Thereafter, the
          Indemnified Party shall deliver to the indemnifying party, within five
          (5) Business Days after the Indemnified Party's receipt thereof copies
          of all notices and documents (including court papers) received by the
          Indemnified Party relating to the Third Party Claim.

     10.5.2 If a Third Party Claim is made against an Indemnified Party, the
          indemnifying party will be entitled to participate in the defense
          thereof and upon notice to the Indemnified Party to assume the defense
          thereof provided that (i) the indemnifying party's counsel is
          reasonably satisfactory to the Indemnified Party and (ii) the
          indemnifying party shall thereafter consult with the Indemnified Party
          upon the Indemnified Party's request for such consultation from time
          to time with respect to such suit, action or proceeding. If the
          indemnifying party assumes such defense, the Indemnified Party shall
          have the right (but not the duty) to participate in the defense
          thereof and to employ counsel, at its own expense, separate from the
          counsel employed by the indemnifying party. The indemnifying party
          shall be liable for the fees and expenses of counsel employed by the
          Indemnified Party for any period during which the indemnifying party
          has not assumed the defense thereof. Should the indemnifying party so
          elect to assume the defense of a Third Party Claim, the indemnifying
          party will not be liable to the Indemnified Party for any legal
          expenses subsequently incurred by the Indemnified Party in connection
          with the defense thereof. Whether or not the indemnifying party
          chooses to defend or prosecute any Third Party Claim, the Parties
          shall cooperate in the defense or prosecution thereof. Such
          cooperation shall include the retention and (upon the indemnifying
          party's request) the provision to the indemnifying party of records
          and information which are reasonably relevant to such Third Party
          Claim,


                                       34







<PAGE>


          and making employees available on a mutually convenient basis to
          provide additional information and explanation of any material
          provided under this Agreement. Whether or not the indemnifying party
          shall have assumed the defense of a Third Party Claim, the Indemnified
          Party shall not admit any liability with respect to, or settle,
          compromise or discharge, such Third Party Claim without the
          indemnifying party's prior written consent. The indemnifying party
          will not be subject to any liability for any settlement made without
          its consent, but such consent will not be unreasonably withheld.

     10.5.3 Any payment pursuant to this Section 10.5 shall be made not later
          than fifteen (15) days after receipt by the indemnifying party of
          written notice from the Indemnified Party stating that any Third Party
          Claim has been paid by any Indemnified Party and the amount thereof
          and the indemnity payment requested.

10.6 EXCLUSIVITY.

     Except as specifically set forth in this Agreement, and except in the case
     of fraud, effective as of the Closing, SBC waives any rights and claims SBC
     may have against Covad, whether in law or equity, relating to the
     investment in the Shares. The rights and claims waived by SBC include,
     without limitation, claims for breach of contract, breach of representation
     or warranty, negligent misrepresentation and all other claims for breach of
     duty. After the Closing, Section 10.1 of this Agreement will provide the
     exclusive remedy for any misrepresentation, breach of warranty, covenant or
     other agreement or other claim arising out of this Agreement, except in the
     case of fraud.

                                   ARTICLE XI

                                  MISCELLANEOUS

11.1 DISPUTE RESOLUTION.

     Any disputes between the Parties arising under this Agreement shall be
     resolved in accordance with the procedures set forth in the Dispute
     Resolution Agreement entered into by Covad and SBC on the same date as this
     Agreement.

11.2 ENTIRE AGREEMENT; AMENDMENT.

     This Agreement (including the attached Schedules and Exhibits) constitutes
     the sole understanding of the parties with respect to the subject matter of
     this Agreement, and supersedes all prior oral or written agreements,
     commitments or understandings with respect to such matters. No amendment,
     modification or alteration of the terms or provisions of this Agreement
     shall be binding unless the same shall be in writing and duly executed by
     the Parties.


                                       35

11.3 SUCCESSORS AND ASSIGNS.

     This Agreement may not be assigned by either Covad or SBC without the
     consent of the other Party (which consent shall not be unreasonably
     withheld) except to any Wholly-Owned Subsidiary of either Covad or SBC that
     agrees to be bound by all of the terms of this Agreement, and provided that
     no such permitted assignment shall relieve the Parties of any liability for
     a breach of this Agreement by such Party or its assignee. This Agreement
     shall be binding upon and shall inure to the benefit of the Parties and
     their respective heirs or successors in interest. A Wholly-Owned Subsidiary
     of Covad shall have the right to perform all or a part of the obligation
     under this Agreement to sell the Shares to SBC provided that Covad receives
     the prior written consent (which shall not be unreasonably withheld) of SBC
     (it being recognized that SBC shall have the right to withhold its consent
     if it determines in its reasonable discretion that the rights afforded it
     under such alternative sale would be less than those afforded it absent
     such alternative sale or if such alternative sale would delay or adversely
     affect the consummation of the transactions contemplated by this
     Agreement).

11.4 RIGHTS AND REMEDIES.

     Unless otherwise provided in this Agreement, the rights and remedies of the
     Parties under this Agreement shall not be mutually exclusive, and the
     exercise of one or more provisions of this Agreement shall not preclude the
     exercise of any other provisions. Each of the Parties confirms that damages
     at law may be an inadequate remedy for a breach or threatened breach of any
     provision of this Agreement. The respective rights and obligations under
     this Agreement shall be enforceable by specific performance, injunction or
     other suitable remedy, it being the intention of this Section 11.4 to make
     clear the agreement of the Parties that their respective rights and
     obligations under this Agreement shall be enforceable in equity as well as
     at law or otherwise.

11.5 COUNTERPARTS.

     This Agreement may be executed in one or more counterparts, each of which
     shall for all purposes be deemed to be an original and all of which shall
     constitute the same instrument.

11.6 MODIFICATION AND WAIVER.

     At any time on or prior to the Closing Date, the Parties by mutual
     agreement may (a) extend the time for the performance of any of the
     obligations or other acts of the other Parties, (b) waive any inaccuracies
     in the representations and warranties contained in this Agreement or in any
     document delivered pursuant to this Agreement, or (c) waive compliance with
     any of the agreements or conditions contained in this Agreement. Any
     agreement on the part of a Party to any such extension or waiver shall only
     be valid if set forth in an instrument in writing signed on behalf of such
     Party.

11.7 EXPENSES.

     Except as specifically provided in this Agreement, SBC and Covad shall each
     pay all costs and expenses incurred by it or on its behalf in connection
     with this Agreement and the transactions contemplated by this Agreement,
     including, without limiting the generality of the foregoing, fees and
     expenses of its own consultants, accountants and counsel.

11.8 NOTICES.

     Any notice, request, instruction or other document to be given under this
     Agreement by any Party to the other Party shall be in writing and shall be
     deemed given upon receipt if delivered personally or by telex or facsimile,
     the next day if by express mail or three days after being sent by
     registered or certified mail, return receipt requested, postage prepaid to
     the following addresses (or at such other address for a party as shall be

11.9 SEVERABILITY.

     In case any one or more of the provisions contained in this Agreement shall
     for any reason be held to be invalid, illegal or unenforceable in any
     respect by a court or other authority of competent jurisdiction, such
     invalidity, illegality or unenforceability shall not affect any other
     provision of this Agreement, and this Agreement shall be construed as if
     such invalid, illegal or unenforceable provision had never been contained
     in this Agreement and, in lieu of each such illegal, invalid or
     unenforceable provision, there shall be added automatically as a provision
     of this Agreement as similar in terms to such illegal, invalid or
     unenforceable provision as may be possible and be legal, valid and
     enforceable, it being the intent of the parties to maintain the benefit of
     the bargain for all Parties.

SBC Communications Inc.
175 East Houston Street
San Antonio, TX 78205

Ladies and Gentlemen:

     We have acted as counsel for Covad Communications Group, Inc., a
Delaware corporation, ("Covad") in connection with a Stock Purchase Agreement
(the "Agreement"), dated as of September __, 2000, by and between SBC
Communications Inc. ("SBC") and Covad.

     This opinion letter is furnished pursuant to Section 2.7.4 of the
Agreement. Capitalized terms used but not defined herein shall have the meanings
ascribed to such terms in the Agreement. In rendering our opinion, we have
examined the following:

     1.        the Restated Certificate of Incorporation of Covad,
          filed January 27, 1999, and the Certificate of Amendment, as filed
          with the Secretary of State of the State of Delaware on July 14, 2000,
          as certified by the Secretary of State of the State of Delaware on
          ____________ (collectively, the "Certificate of Incorporation");

     2.       the By-Laws of Covad, as in effect on the date hereof, as
          certified by the Secretary of Covad as of the date hereof (the
          "By-Laws");

     3.        photocopies of executed originals or counterparts of the
          Agreement;

     4.        resolutions of the Board of Directors of Covad adopted at a
          meeting held on _____________, 2000 and resolutions of the Pricing
          Committee of the Board of Directors of Covad by unanimous written
          consent dated as of September __, 2000, as in effect as of the date
          hereof (collectively, the "Resolutions");

     5.        the certificate of an officer of Covad dated as of the date
          hereof as to certain factual matters, a copy of which is attached
          hereto as EXHIBIT A (the "Officer's Certificate");

     6.        the certificate of the Secretary of Covad dated as of the date
          hereof certifying as to (A) the Certificate of Incorporation, (B) the
          By-Laws, (C) the Resolutions and (D) a specimen of the certificate
          representing the Shares (the "Secretary's Certificate"), a copy of
          which is attached hereto as EXHIBIT B; and

<PAGE>

     7.        the certificates, statements and representations made by officers
          of Covad in the closing documents delivered pursuant to the Agreement
          (the "Closing Certificates").

In our examination of the foregoing, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as certified,
photostatic or facsimile copies and the authenticity of the originals of such
latter documents, and the legal capacity of natural persons. We have also
assumed the absence of any agreement or understanding or document that would
modify, supplement or amend any of the documents reviewed by us.

     As to any facts material to the opinions expressed herein, and as to the
materiality of certain facts, we have relied without independent verification,
among other things, upon the representations made by Covad and SBC in the
Agreement, certificates of public officials, the Closing Certificates, the
Officer's Certificate and the Secretary's Certificate. Our opinion in paragraph
1 as to the good standing of Covad in Delaware and the qualification of Covad as
a foreign corporation is based upon certificates from the appropriate officials
of the states listed on Schedule 1 concerning such status and qualification. Our
opinion in paragraph 5 as to the authorized capital stock of Covad is based upon
the Certificate of Incorporation. All of the opinions referenced in this
paragraph are rendered as of the respective dates of such certificates. We also
have made such inquiry of officers and representatives of Covad as we determined
to be necessary in order to give such opinions.

     In rendering this opinion, we have assumed that each party (other than
Covad) that has executed or will execute an agreement to which Covad is a party
has all requisite power and authority and has taken all necessary action to
execute and deliver such agreement and to perform the transactions contemplated
thereby, and that each such agreement is the legal, valid and binding obligation
of such party (other than Covad) enforceable against such party in accordance
with its terms.

     In basing our opinions and other matters set forth herein on "our
knowledge" or matters "known to us," the words "our knowledge" or "known to us,"
or other words to that effect, signify that, in the course of our representation
of Covad in connection with the Agreement, no information has come to the
attention of the individual attorneys at the firm providing such representation
that would give them actual knowledge that any such opinions or other matters
are not accurate or that any of the information on which we have relied is not
accurate and complete. Except as otherwise stated herein, we have undertaken no
investigation or verification of such matters. No inference as to our knowledge
of such matters should be drawn from our representation of Covad in this or any
other instance.

     Based upon the foregoing and subject to the limitations and qualifications
hereinafter set forth, we are of the opinion that:

     1.   Covad is a corporation validly existing and in good standing under the
          laws of the State of Delaware with all requisite corporate power and
          authority to own its properties and conduct its business as it is now
          being conducted, and is duly qualified to do business as a foreign
          corporation and is in good standing in each jurisdiction

                                        2

<PAGE>

          where the ownership of its properties or the conduct of its business
          makes such qualification necessary, except in those jurisdictions
          where failure to be so qualified or in good standing would not, in our
          judgment, be expected to have a Material Adverse Effect.

     2.   Covad has all requisite corporate power and authority to execute,
          deliver and perform its obligations under the Agreement. Covad has
          taken all corporate action necessary to authorize the Agreement and
          the issue, sale and delivery of the Shares.

     3.   The Shares are duly authorized and, when issued and delivered to SBC
          pursuant to the Agreement, will be duly and validly issued and fully
          paid and nonassessable. To our knowledge, the Shares are not and will
          not at the time of issuance be subject to any preemptive or
          subscription or similar rights of any shareholder contained in the
          Certificate of Incorporation, the Bylaws, or any agreement identified
          to us by the Company as containing any such rights. To our knowledge
          based on agreements identified to us by the Company, there are no
          outstanding options or rights of any kind to acquire or subscribe for
          any Shares to be issued and sold pursuant to the Agreement nor to our
          knowledge are there any obligations to issue, sell or otherwise cause
          to become outstanding any such options or rights. To our knowledge
          based on agreements identified to us by the Company, Covad is not a
          party to any voting trusts, proxies, voting agreements or other
          agreements with respect to the voting of the capital stock of Covad.

     4.   Neither the execution and delivery by Covad of the Agreement, nor the
          consummation of the purchase and sale of the Shares contemplated
          thereby, nor compliance by Covad with its obligations thereunder,
          will, with or without the giving of notice or the lapse of time, or
          both: (i) conflict with, or result in a breach or violation of, or
          constitute a default under, any provision of the Certificate of
          Incorporation or By-Laws or, to our knowledge, any law, rule or
          regulation customarily applicable to transactions of the type
          contemplated by the Agreement, order, injunction or decree of any
          court, administrative authority or arbitrator applicable to Covad or,
          to our knowledge, any property or Assets of Covad, or will conflict
          with, or result in a breach or violation of or constitute a default in
          the performance, observance or fulfillment of any obligation under, or
          constitute, or, with the giving of notice or lapse of time or both,
          would constitute, an event of default by Covad, or result in the
          acceleration of any obligation, or require any consent or approval,
          under, any agreement or instrument identified on Schedule 2 hereto to
          which Covad is a party or by which it or any of its properties or
          Assets are bound, except where such conflicts, breaches, violations,
          defaults or events of default or the absence of such required consents
          or approvals (other than with respect to the Certificate of
          Incorporation and Bylaws) would not, in our judgment, be expected to
          have a Material Adverse Effect; or (ii) require any action, consent or
          approval of, or filing with, any Governmental Authority customarily
          applicable to transactions of the type contemplated by the Agreement,
          except for the filing required by the HSR Act and the expiration of
          the waiting periods associated with such filing and for such actions,
          consents, approvals or filings that have been made prior to the
          Closing or

                                        3

<PAGE>

          with respect to which the failure to make would not, in our judgment,
          be expected to have a Material Adverse Effect.

     5.   The authorized capital stock of Covad as of the date hereof is as set
          forth on Schedule ____ of the Agreement.

     6.   Based solely on the representations, warranties and agreements of
          Covad and SBC, and on the truth and accuracy of the representations
          and agreements deemed to be made by Covad and SBC, in the Agreement,
          it is not necessary in connection with the offer, sale and delivery of
          the Shares to SBC under the Agreement to register the Shares under the
          Securities Act or register or qualify the Shares under state
          securities laws; provided, however, that we express no opinion with
          respect to the conditions under which the Shares may be further
          resold.


     The foregoing opinions are, with your concurrence, predicated upon and
qualified by the following:

     1.   The foregoing opinions are based upon and are limited to the \
          published compilations of the General Corporation Law of the State of
          Delaware and the relevant laws of the United States of America,
          excluding in all cases (i) all regulatory laws, regulations, orders,
          rules, pronouncements and other matters relating to compliance with
          regulatory matters, including without limitation the Communications
          Act of 1934, as amended (including amendments made by the
          Telecommunications Act of 1996), 47 U.S.C.ss151 ET SEQ., as well as
          the regulations, rules, policies and published decisions of the
          Federal Communications Commission, and any court's interpretation of
          same, and the statutory laws, regulations, rules, policies and
          published decisions of the public utilities commissions and similar
          regulatory agencies and any court's interpretation of same of any of
          the United States of America and (ii) all matters relating to
          antitrust laws. We render no opinion with respect to the laws of any
          other jurisdiction.

     2.   Our opinions are limited to the matters set forth in this letter, and
          no other opinions should be inferred beyond the matters expressly
          stated.

     This opinion letter is solely for the benefit of the addressee shown on the

                                     (Date)

SBC Communications Inc.
175 East Houston Street
San Antonio, TX  78205


Ladies and Gentlemen:

     You have requested our opinion as to the enforceability under Delaware law
of the obligations of Covad Communications Group, Inc., a Delaware corporation
(the "Company"), under the Stock Purchase Agreement dated__________, 2000 (the
"Agreement") between the Company and SBC Communications Inc., a Delaware
corporation ("SBC"). Capitalized terms not defined herein shall have the
meanings given them in the Agreement.

     For purposes of rendering our opinion, Irell & Manella, counsel to the
Company, has provided to us and we have reviewed the Agreement. We have not
reviewed any other documents in connection with rendering our opinion and have
assumed that there are none that are contrary to or inconsistent with our
opinion. We have also assumed that each of the Company and SBC is duly
organized, validly existing and in good standing under the laws of Delaware;
that the issuance of the Shares pursuant to the Agreement has been duly
authorized by all necessary corporate action; that the Company will have a
sufficient number of shares of Common Stock authorized by its certificate of
incorporation that have not been issued, subscribed for, or otherwise committed
to be issued, in order to permit the Company to issue the Shares pursuant to the
terms of the Agreement; that the purchase price per share of the Shares

SBC Communications Inc.
[Date]
Page 2

is greater than the par value per share of Common Stock; that each party to the
Agreement has the corporate power to execute, deliver and perform its
obligations under the Agreement; that the Agreement has been duly authorized,
executed and delivered by each party thereto; and that the Agreement constitutes
the legal, valid and binding obligation of SBC, enforceable against SBC in
accordance with its terms. We express no opinion with respect to the Delaware
Securities Act, 6 DELAWARE CODE Section 7301 ET SEQ., or any rules or
regulations promulgated thereunder, or to any agreements, exhibits, schedules or
other documents referred to or incorporated by reference in the Agreement other
than the Agreement itself.

     Based upon and subject to the foregoing and to the qualifications set forth
below, and limited in all respects to matters of Delaware law, it is our opinion
that the Agreement constitutes the legal, valid and binding obligation of the
Company, enforceable against it in accordance with its terms, except as such
enforceability may be limited by (i) bankruptcy, insolvency, moratorium,
fraudulent conveyance, receivership and other laws affecting the rights and
remedies of creditors generally, (ii) the application of equitable principles
(whether in a proceeding at law, at equity or otherwise), and (iii) standards of
good faith, fair dealing, course of dealing, materiality and reasonableness that
may be applied by a court to the exercise of rights and remedies generally.

     Our opinion is subject to the following qualifications:

     1. We express no opinion as to the Company's obligations with respect to
indemnification, or any waivers by the Company, except to the extent permitted
by applicable law.

     2. We express no opinion as to any obligation of the Company to repurchase
the Shares, as set forth in Section 7.6 of the Agreement, to the extent it lacks
sufficient surplus, as defined under Delaware law, to make such repurchase.

     3. We express no opinion with respect to Section 10.4 of the Agreement to
the extent it purports to extend any otherwise applicable statute of
limitations.

     The opinions set forth above are solely for your benefit in connection with
the entry into the Agreement by the

Company and may not be relied upon for any other purpose or by any other person
or entity without our prior written consent.
