I am pleased to extend to you an offer of employment for the position of
President and CEO of Verilink Corporation. The terms and conditions of your
employment will be as follows:

1.    Your employment will commence not later than April 12, 1999. You will
      report to the Company's Board of Directors.

2.    Your base compensation will initially be $11,538.47 paid bi-weekly
      (annualized salary of $300,000.00). Executive compensation is reviewed
      annually after the end of Verilink's June 30 fiscal year end. Any increase
      in salary is at the sole discretion of the Board of Directors.

3.    You will receive such benefits as are customarily granted to officers of
      Verilink. Attachment 1 sets forth the benefits currently available to
      Verilink employees generally and to Verilink executive officers, except
      that your automobile allowance will be $1,000.00 per month. Please note
      that officers do not participate in the profit sharing plan. These
      benefits are subject to review from time-to-time by the Compensation
      Committee of the Board of Directors.

4.    Contingent upon your acceptance of this offer of employment, and subject
      to the Board of Directors' approval, Verilink will grant you a
      Non-Qualified Stock Option which gives you the right to purchase, under
      terms stated in your Stock Option Agreement, 400,000 shares of Verilink
      Common Stock at the fair market value as determined by the Board of
      Directors on the date of the grant. Vesting will occur over 4 years at the
      rate of 2.08% (1/48th) at the end of each month, assuming continuous
      employment.

5.    You will be eligible for participation in Verilink's Management Incentive
      Plan for fiscal 2000 (July 1, 1999 - June 30, 2000) and thereafter. The
      Plan will provide for a target potential payout to you of 50% of your base
      salary upon achievement of

      your objectives under the Plan, but in no event less than a guaranteed
      payment to you for fiscal 2000 of one-half of your target bonus (25% of
      base salary), which guaranteed payment is subject to completion and
      approval by the Board of a corporate business plan prior to the end of
      fiscal 1999 and to your still being employed by Verilink at the end of
      fiscal 2000.

6.    During the first year of employment, if your employment is terminated by
      Verilink other than for cause, whether or not a change of control has
      occurred, you will receive two years' base salary, including applicable
      benefits, with vested options available to execute for up to a period of
      twelve additional months. If your employment is terminated by Verilink
      other than for cause during the second year of employment, you will
      receive one year's base salary, including applicable benefits, with vested
      options available to execute for up to a period of twelve additional
      months. If such termination occurs after a change in control, you will
      also receive such additional benefits as are provided in the Verilink
      Change of Control Severance Benefits Agreement (Attachment 2). At
      Verilink's option, the foregoing severance may be paid as salary
      continuation or as a lump sum. After two years of employment, any
      severance benefits will be subject to the Change of Control Severance
      Benefits Agreement and other then existing practices applicable to
      Verilink's executive officers. For purposes of this paragraph, "cause"
      shall be defined as any act or failure to act involving dishonesty towards
      Verilink; unethical business practices; embezzlement or misappropriation
      of corporate funds, property or proprietary information; unreasonable and
      willful refusal to perform the duties required by Verilink; willful breach
      of this Agreement or habitual neglect of duties and responsibilities,
      other than due to illness or disability; aiding and abetting a competitor;
      or participation in any fraud or any criminal activities.

7.    For a period of up to 180 days after the commencement of your employment,
      Verilink will provide you with temporary housing. In addition, Verilink
      shall reimburse you for your moving costs, travel associated with your
      move, and other relocation costs. Attachment 3 sets forth Verilink's
      standard relocation policies. You and Verilink's Human - Resources
      Department will mutually agree upon the application of those policies to
      your situation. The total relocation assistance shall not exceed $125,000.
      If you voluntarily terminate your employment within 12 months after
      commencement of employment, you will repay Verilink the amount of the
      foregoing relocation payments. If you voluntarily terminate your
      employment between 12 months and 18 months after commencement of
      employment, you will repay Verilink a pro-rata portion of the relocation
      payment based upon the number of months remaining to 18 months divided by
      six. Please understand this offer of relocation is a confidential,
      one-time offer for you only. It is not Verilink's intention for this
      relocation package to become permanent policy.

      employment and you make a written offer that is accepted to purchase a new
      home in California, which purchase is scheduled to close prior to the sale
      of your existing home, Verilink shall loan you an amount equal to the
      "equity" in your existing home (fair market value less encumbrances). That
      loan will be interest-free and shall be repaid by you on the earlier of
      the closing sale of your existing home or twelve months after the
      commencement of your employment. You agree to use your best efforts to
      sell your existing home as soon as possible. During the first six months
      of your employment, Verilink will also reimburse you for any mortgage
      payments upon your existing home made by you after you purchase a new home
      in California.

      employment with Verilink is voluntarily entered into and is for no
      specific period. As a result, you are free to resign at any time, for any
      reason or for no reason. Similarly, Verilink is free to conclude its
      at-will employment relationship with you at any time, with or without
      cause.

11.   In the event of any dispute or claims relating to or arising out of our
      employment relationship, you and Verilink agree that all such disputes
      shall be fully and finally resolved by binding arbitration conducted by
      the American Arbitration Association in San Jose, California. However, we
      agree that this arbitration provision shall not --- apply to any dispute
      or claims relating to or arising out of the misuse or misappropriation of
      the Company's trade secrets or proprietary or confidential information or
      to enforcement of your rights under the Change of Control Severance
      Benefits Agreement.
