          Re:  Assumption and Extension of Letter Agreement dated June 28, 1999
               between you and LISN Holdings, Inc. (the "Original Letter")

Dear Jack:

          As you know, Orius Corp. ("Orius") acquired LISN Holdings, Inc.
("LISN") in December 1999 (the "Acquisition"). By signing this letter agreement
in the space provided below, you hereby agree with LISN and Orius as follows:

1.   Assumption of Original Letter. Orius hereby assumes all of LISN's
     obligations under the Original Letter and succeeds to all of LISN's rights
     under the Original Letter. Effective for the period commencing at the
     closing of the Acquisition, Orius is hereby substituted for LISN in the
     Original Letter.

2.   Extension of Term. As you know, the term of the consulting arrangement
     under the Original Letter expired as of the end of November 30, 1999,
     subject to renewal upon mutual agreement of you and LISN for up to two
     additional, consecutive six month periods. Orius and you previously agreed
     to the first of such extensions, and Orius and you hereby agree to the
     second of such extensions, so that the Term (as defined in the Original
     Agreement) will now continue through November 30, 2000, subject to further
     renewal upon mutual written agreement of you and Orius for up to two
     additional, consecutive six month periods.

3.   Stock Options. LISN issued stock options to you and, upon closing of the
     Acquisition, those options converted into options to acquire Orius stock.
     Such options were issued in satisfaction of, and supercede, LISN's
     obligations under paragraph 2(c) of the Original Letter.

4.   D&O Insurance. In a letter to you dated [June 28, 1999], Willis Stein &
     Partners II, L.P. and Willis Stein & Partners Dutch, L.P. (collectively,
     "Willis Stein") provided certain assurances to relating to director's and
     officer's liability insurance. You agree that, effective automatically at
     such time as Orius obtains a director's and officer's liability insurance
     policy covering any period, Willis Stein shall automatically be released
     from all liability with respect to such period under that letter.

     a)   LISN will pay you compensation at the rate of $15,000 per month for
          up to five full days of consulting services for each month in which
          you provide consulting services in accordance with paragraph 1 above.
          Consulting in excess of five days per month will be compensated at the
          rate of $3,000 per day. Such payments for services rendered in any
          month shall be made within 15 days following the end of such month.

     b)   So long as you serve on LISN's board of directors, you will receive
          director's fees consistent with those paid by LISN to its other

     c)   At such time as this letter agreement becomes effective, LISN will
          grant to you, in accordance with the terms of its executive stock

          consultant to or director of LISN shall be the exclusive property of
          LISN, that you will not disclose any of such information to any third
          parties without LISN's prior written, and that you will use your
          reasonable best efforts to ensure that none of such information is

          confidentiality provisions with regard to information which was or
          came to be in the public domain through no fault of your own or of any
          of your agents. If you breach the provisions of this paragraph, the
