      (the “Amendment Effective Date”) by and between Qwest

    WHEREAS,
      Pac-West and Customer entered into that certain Dial Access Services Agreement
      effective as of January 31, 2002 (the “Agreement”);

    NOW,
      THEREFORE,
      in
      consideration of the foregoing and other good and valuable consideration, the
      receipt and sufficiency of which are hereby acknowledged, the Parties agree
      as
      follows:

     

    
      	
              1.

            	
               
                Section 4 of the Agreement shall be deleted in its entirety and replaced
                by the following Section 4:

            


    

     

    “4. Minimum
      Service Commitment

     

    Except
      as
      otherwise provided herein, Customer agrees to maintain the Ports set forth
      below
      for the duration of the respective Service Terms (“Port Commitment”). The
      Parties agree to work cooperatively to complete a deployment plan within thirty
      (30) days after the Effective Date that will result in the fastest reasonable
      delivery and activation for the entirety of the Port Commitment.

     

    Phase
      1 Port Commitment:
      Minimum
      of [**] Ports activated within 45 days of the Effective Date, at the locations
      set forth in Exhibit 4.

     

    Phase
      2 Port Commitment:
      Minimum
      of [**] additional Ports activated on or before June 30, 2002, at the locations
      set forth in Exhibit 4.

     

    Phase

      Minimum
      of [**] additional Ports activated the later of January 1, 2003 or the date
      the
      Ports are accepted by Qwest in accordance with Section 11 of the Agreement,
      at
      the locations set forth in Exhibit 4.

     

    In
      the
      event that Qwest desires early activation of any Ports, Pac-West agrees to
      exercise its commercially reasonable efforts, subject to resource and personnel
      constraints, to accommodate Qwest’s request.”

     

    
      	2.	
               
                All other terms and conditions in the Agreement shall remain in full
                force
                and effect and be binding upon the Parties. This Amendment and the
                Agreement set forth the entire understanding between the Parties
                as to the
                subject matter herein, and in the event there are any inconsistencies
                between the two documents, the terms of this Amendment shall
                control.
