Agreement, and Executive desires to be so employed.

                                     AGREEMENT

terminated by either party in accordance with Section 5 of this Agreement.

     3.   POSITION AND DUTIES.  During the Employment Period, Executive shall
serve as Senior Vice President, Corporate Communications and External Affairs of

consent of the Board of Directors of the Company (the "BOARD")

     4.   COMPENSATION AND RELATED MATTERS.

          (a)  EQUALIZATION PAYMENT.  To compensate Executive for certain
benefits that he may lose or forfeit as a result of his termination of
employment with his former employer, ICG Communications, Inc., and commencement

accordance with the Company's customary payroll schedule and practices.
Executive's Base Salary shall be subject to annual reviews commencing October

all purposes of this Agreement. All compensation paid to Executive shall be
subject to withholding and other employment taxes imposed by applicable law.


(c)  ANNUAL BONUS. The Board's compensation committee (the "COMPENSATION
COMMITTEE") shall review Executive's performance at least once annually during
each year of the Employment Period and, based on Executive's performance,
recommend whether the Company should award Executive a cash bonus ("BONUS") in
order to reward Executive for services rendered to the Company and/or as an
incentive for continued service to the Company.  The amount of Executive's
Bonus, if any, shall be determined in the reasonable discretion of the
Compensation Committee and shall be dependent upon, among other things, the
achievement of certain performance levels by the Company, including, without
limitation, (i) the nature, magnitude and quality of the services performed by
Executive for the Company, (ii) the condition (financial and other) and results
of operations of the Company and (iii) the compensation paid for positions of
comparable responsibility and authority within the telecommunications industry.

exercise price of $4.50 per share.  The Stock Option will be granted under one
of the Company's stock option plans and the terms and conditions of the Stock
Option will be determined in accordance with the applicable stock option plan.
          (e)  EXPENSES.  The Company shall promptly reimburse Executive for all
reasonable business expenses upon the presentation of reasonably itemized

procedures now in force or as such policies and procedures may be modified with
respect to all senior executive officers of the Company.

          (f)  WELFARE AND PENSION PLANS.  In addition to Executive's Base
Salary and any incentive compensation and bonuses awarded to Executive
hereunder, he (and his family) shall be entitled to participate, to the extent
that he is (and they are) eligible under the terms and conditions thereof, in
any pension, retirement, hospitalization, insurance, disability or medical
service plan generally available to the executive officers of the Company that
may be in effect from time to time during the Employment Period.  The Company
shall be under no obligation to institute or continue the existence of any such
employee benefit plan.

          (a)  DEATH.  Executive's employment hereunder shall terminate upon his
death.

          (b)  DISABILITY.  If, as a result of Executive's incapacity due to 
physical or mental illness, Executive shall have been substantially unable to 
perform his duties hereunder for an entire period of thirty (30) consecutive 
days, and within thirty (30) days after written Notice of Termination (as 
defined in Section 6(a)) is given after such thirty (30) day period, 
Executive shall not have returned to the substantial performance of his 
duties on a full-time basis, the Company shall have the right to terminate 
Executive's employment hereunder for "Disability," and such termination in 
and of itself shall not be, nor shall it be deemed to be, a breach of this 
Agreement.

          (c)  CAUSE.  The Company shall have the right to terminate Executive's
employment for Cause (as defined), and such termination in and of itself shall
not be, nor shall it be deemed to be, a breach of this Agreement.  For purposes
of this Agreement, the Company shall have "Cause" to terminate Executive's
employment upon Executive's:

               (i)   conviction of, or plea of guilty or nolo contendere to,
     any crime constituting a felony;

               (ii)  commission of a material act of dishonesty, fraud,
     misrepresentation or other act of moral turpitude that would, in the
     Board's reasonable judgment, prevent the effective performance of his
     duties hereunder;

               (iii) continued failure to substantially perform his duties
     hereunder to the reasonable satisfaction of the Board (other than such
     failure resulting from Executive's incapacity due to physical or mental
     illness or subsequent to the issuance of a Notice of Termination by
     Executive for Good Reason (as defined in Section 5(d)) after demand for
     substantial performance is delivered by the Board in writing that
     specifically identifies the manner in which the Board believes Executive
     has not used reasonable best efforts to substantially perform his duties;
     or

               (iv)  willful misconduct (including, but not limited to, a
     willful breach of the provisions of Section 8) that is, in the Board's
     reasonable judgment, injurious to the Company or to any entity in control
     of, controlled by or under common control with the Company ("AFFILIATE").

     For purposes of this Section 5(c), no act, or failure to act, by Executive
shall be considered "willful" unless committed in bad faith and without a
reasonable belief that the act or omission was in the best interests of the
Company or any Affiliates thereof; PROVIDED, HOWEVER, that the requirements
outlined in paragraphs (iii) or (iv) above shall be deemed to have occurred if
Executive's action or non-action continues for more than ten (10) days after
Executive has received written notice of the inappropriate action or non-action.
This Section 5(c) shall not prevent Executive from challenging the Board's
determination that Cause exists or that Executive has failed to cure any act (or
failure to act) that purportedly formed the basis for the Board's determination,
under the arbitration procedures set forth in Section 10 below.

                                      3

<PAGE>

Reason" within thirty (30) days after Executive has actual knowledge of the
occurrence, without the written consent of Executive, of one of the following
events that has not been cured within thirty (30) days after written notice
thereof has been given by Executive to the Company (PROVIDED, that with respect
to this Section 5(d), the Company shall have the right to challenge Executive's
determination that he has the right to terminate his employment for "Good
Reason" under the arbitration procedures set forth in Section 10 below):

               (i)   a reduction by the Company in Executive's Base Salary or a
     failure by the Company to pay any such amounts when due;

               (ii)  any purported termination of Executive's employment for
     Cause which is not effected pursuant to the procedures of Section 5(c) (and
     for purposes of this Agreement, no such purported termination shall be
     effective);

               (iii) the Company's failure to provide the Stock Option or the
     Company's material breach of one or more of the stock option agreements
     pursuant to which the Stock Option was issued to Executive;

               (iv)  the Company's failure to substantially provide any
     material employee benefits due to be provided to Executive; or

               (v)   the Company's failure to provide in all material respects
     the indemnification set forth in Section 9 of this Agreement.

     Executive's continued employment during the thirty (30) day period referred
to above in this paragraph (d) shall not constitute Executive's consent to, or a
waiver of rights with respect to, any act or failure to act constituting Good
Reason hereunder.

          (e)  WITHOUT GOOD REASON.  Executive shall have the right to terminate
his employment hereunder without Good Reason by providing the Company with a

by the Company or by Executive during the Employment Period (other than

               (ii)  the Company shall reimburse Executive pursuant to Section

drawings, documents, models, equipment, and the like relating to the Company's
business, which Executive has control over shall not be removed from the
Company's premises by Executive without the Board's written consent, unless such

Executive's carrying out his duties under this Agreement and, if so removed by
Executive, shall be returned to the Company promptly after termination of
Executive's employment hereunder, or otherwise promptly after removal if such
removal occurs following termination of employment.  Executive shall assign to
