                              EMPLOYMENT AGREEMENT

     This Employment Agreement is made and entered into by and between
Telocity, Inc. (the "Company") and Edward J. Hayes, Jr. (the "Employee") on
December 10th, 1999.

1.   POSITION AND DUTIES: The Employee shall be employed by the Company as its
     Executive Vice President and Chief Financial Officer reporting only to the
     Company's Chief Executive Officer (CEO) beginning no later than January
     3rd, 2000 (the "Effective Date"). Employee agrees to devote his full
     business time, energy and skill to his duties at the Company. These duties
     shall include those duties customarily performed by the Chief Financial
     Officer, as well as those duties that may be assigned by the CEO from time
     to time.

2.   TERM OF EMPLOYMENT. The Employee's employment with the Company will be for
     no specified term, and may be terminated by the Employee or the Company at
     any time, for any reason, with or without cause, and neither the Employee
     nor the Company shall have any further obligation or liability whatsoever
     under this Employment Agreement to the other, except as may be
     specifically set forth herein.

3.   COMPENSATION: The Employee shall be compensated by the Company for his
     services as follows:

     A.   Base Salary. The Employee shall be paid a monthly Base Salary of
          $20,833.33 per month ($250,000.00 [Two Hundred and Fifty Thousand
          U.S. Dollars] on an annualized basis), subject to applicable
          withholding, in accordance with the Company's normal payroll
          procedures. The Employee's base salary shall be reviewed on at least
          an annual basis and may be increased as appropriate. In the event of
          such an increase, the new amount shall become the Employee's Base
          Salary.

     B.   Benefits: The Employee shall have the right, on the same basis as
          other members of the Company's senior management, to participate in
          and receive benefits under any of the Company's Employee Benefit
          Plans (broadly structured in Attachment A), as such plans may be
          modified from time to time. The Employee shall be entitled to the
          benefits afforded to other members of senior management under the
          Company's vacation, holiday and business expense reimbursement
          policies. The Employee will be entitled to five (5) weeks vacation.
          To the extent the Employee is unable in the execution of his duties
          and responsibilities to take the allotted (and any previously-
          carried-over) vacation in any given year, the Employee will be
          eligible to roll-over up to five (5) weeks of vacation annually.

     C.   Annual Incentive Bonus: By way of description and not limitation, the
          Employee shall be entitled to the benefits afforded to other members
          of senior management under the Company's Bonus Program (broadly
          structured in Attachment B regarding components based upon company
          performance and individual performance in any given fiscal year). The
          Bonus Program shall be defined within thirty (30) days of the
          Effective Date and which shall, in any case, contain a target bonus
          amount of 50% of the Employee's base salary. The range of this annual
          incentive bonus shall be determined by senior management as it
          formulates the mechanics of the Company's management incentive
          compensation plan.

     D. Hiring Bonus: In order to incent the Employee to join the Company and
        address certain forfeitures, including forfeited stock options, prompted
        by leaving the Employee's current employer, and to reimburse the
        Employee for certain relocation expenses, the Company will provide a
        one-time Hiring Bonus award of $325,000.00 (Three Hundred and
        Twenty-Five Thousand U.S. Dollars), payable within thirty (30) days of
        the Effective Date.

4.   STOCK OPTIONS: The Employee shall be granted the option to purchase 370,000
     (Three Hundred and Seventy Thousand) shares of the Company's Common stock
     (the "Stock Options"), at an exercise price per share equal to the fair
     market value of the Company's Common Stock on the date of grant as
     determined by the Board in its sole discretion. Such grant and
     determination shall be made no later than thirty (30) days after the
     Effective Date. To the extent possible, such Option will be an incentive
     stock option. The Stock Options shall vest monthly at the rate of 1/48 per
     month; however there shall be a twelve (12) month cliff vesting period,
     upon which the first 1/4th of the Stock Options shall vest. Upon the
     termination of the Employee's employment in accordance with the provision
     of Paragraph 6 below, the Stock Options shall vest as described in such
     provisions. Except as provided herein and in Paragraph 6 below, the Stock
     Options shall be subject to the terms of the Company's Stock Option Plan
     and the Company's standard incentive and non-statutory Stock Option
     Purchase Agreements (the "Standard Agreements" described in Attachment D),
     provided pursuant tot he Company's Stock Option Plan. The Employee will be
     permitted to exercise the option in full prior to vesting in the underlying
     shares, subject to the Company's right to repurchase any unvested shares
     (subject to Paragraph 6 below) at the Employee's original cost upon his
     termination of employment, as provided in the Standard Agreements. In
     addition, the Company shall permit the Employee to pay the option exercise
     price with a full recourse loan (secured by the shares acquired with the
     loan) at the lowest interest rate available to avoid the imposition of
     imputed income under the tax laws to assist the Employee to exercise the
     Stock Options. Such loan shall be repayable upon the earlier of: (i) the
     fifth year anniversary of the Effective Date; (ii) the date six (6) months
     after termination of the Employee's employment for any reason; or (iii) the
     date twelve (12) months after the Employee is first eligible to sell shares
     of the Company's stock that he holds following an initial public offering
     of the Company's shares; provided however that in the event of termination
     of the Employee Without Cause or the employee's Resignation for Good
     Reason, such loan shall be repayable upon the earlier of the events stated
     in clauses (i) or (iii) immediately preceding. Going forward, the Employee
     will be eligible to receive additional Stock Options at amounts and
     exercise prices then prevailing, but consistent with the proportional
     amounts of the original grant vis-a-vis other senior manager's original
     grant allotments.

5.   DEFINITIONS APPLICABLE TO TERMINATIONS: For the purposes of "terminations"
     as described in Paragraph 6, the following definitions shall apply:

          iii. an immediate vesting of all Stock Options granted and unvested as
               of the date of death or disability. These Stock Options would be

               the duration of the exercise period originally granted under the
               Company's Stock Option Plan.

     D.   Termination Without Cause and/or Resignation for Good Reason: If the
          Employee's employment is terminated by the Company without Cause, or

          (provided that the underlying conditions persist for fifteen (15)
          business days after written notice to the Company), then the Employee
          shall be entitled, on such date, to all of the following:

          i.   all accrued compensation, benefits and vesting earned through the
               date of termination or resignation;

          iii. the removal of any "cliff date" in calculating the number of
               Stock Options vested upon such date; and

          iv.  The greater of: an immediate six (6) month acceleration in the
               vesting schedule, or fifty percent (50%) of any unvested Stock
               Options, shall be deemed to vest immediately on the date of
               termination or resignation. These vested, and all previously
               vested and unexercised, Stock Options would be then deemed
               immediately exercisable and remain exercisable for the duration
               of the exercise period originally granted under the Company's
               Stock Option Plan.

7.   EMPLOYEE INVENTIONS AND PROPRIETARY RIGHTS ASSIGNMENT AGREEMENT: The

     standard Employee Inventions and Proprietary Rights Assignment Agreement
     (as described in Attachment E).

     as may be signed by the Company's other officers and directors from time to
     time. The Employee will be covered under the Company-provided Directors'
     and Officers' Liability Insurance Policies, which protections shall be
     commensurate with the duties, responsibilities and risks of the Chief
     Financial Officer position.

10.  DISPUTE RESOLUTION: In the event of any dispute or claim relating to or
     arising out of this Employment Agreement (including, but not limited to,
     and claims of breach of contract, wrongful termination or age, sex, race or
     other discrimination), the Employee and the Company agree that all such
     disputes shall be fully and finally resolved by binding arbitration
     conducted by the

     incurred by the Employee; (ii) if the action brought by the Employee
     prevails in the arbitration, the Company shall be liable to reimburse the
     Employee his incurred attorney's fees, arbitration costs and/or other costs
     associated with the action or actions.

     or transfer any of his rights, obligations or benefits under the Employment
     Agreement, except as otherwise noted herein. This agreement may be assigned

     terms and conditions of his employment with the Company. To the extent that
     there is any inconsistency between this Employment Agreement and any other

     Employment Agreement will govern. This Employment Agreement supersedes all
     prior negotiations, representations or agreements between the Employee and
     the Company, whether written or oral, concerning the Employee's employment
     by the Company.

15.  VALIDITY: If any one or more of the provisions (or any part thereof) of
