              GENERAL RELEASE, COVENANT NOT TO SUE AND AGREEMENT

         This GENERAL RELEASE, COVENANT NOT TO SUE AND AGREEMENT (this
"Agreement") is by and between ICG COMMUNICATIONS, INC., a Delaware corporation
(which entity, together with its parents, subsidiaries and affiliates is
referred to herein as the "Company"), and Douglas A. Falk ("Employee").

         WHEREAS, the Company and Employee agree to terminate the employment
relationship between them; and

         WHEREAS, the Company and Employee agree to settle and release all
actual and potential claims they may have against one another arising out of or
in connection with the employment of Employee by the Company, the terms and
conditions of Employee's employment, the termination of such employment and any
other action, event or matter prior to the date of this Agreement; and

         WHEREAS, Employee has substantial knowledge of the Company's
operations, customers, vendors, suppliers and other proprietary and confidential
information, and the Company desires for Employee to agree to protect such
confidential information from disclosure and to make certain other covenants and
agreements with the Company.

         NOW, THEREFORE, in consideration of the mutual promises, covenants and
agreements contained herein and for other good and valuable consideration, the
parties agree as follows:

         1.  TERMINATION OF EMPLOYMENT RELATIONSHIP. This Agreement evidences
the termination of the employment relationship between Employee and the Company

         4.   PAYMENT TO EMPLOYEE.

              4.1   Conditioned upon the full execution of this Agreement, and
the lapse of the seven (7) day period described in Section 12 below, the Company
shall pay Employee on or before January 25, 2000 the total sum of Four Hundred
Sixty-Eight Thousand Two Hundred Sixty-Five and 07/100 Dollars ($468,265.07),
less applicable withholding taxes and other governmental obligations. This
amount represents severance in the amount of $68,265.07, less applicable
withholding taxes and other governmental obligations, and a bonus in the amount
of $400,000.00, less applicable withholding taxes and other governmental
obligations, for his services in connection with the sale of ICG Satellite

              4.2   The Company will permit Employee to continue participation
in the Company's Medical/Dental/Vision benefit plans at Employee's present level
through and including January 31, 2000, at which time all such benefits shall be
terminated. At that time, Employee may be eligible to continue appropriate
coverage pursuant to COBRA, subject to COBRA rules and provisions. Conditioned
upon the full execution of this Agreement, and the lapse of the seven (7) day
period described in Section 12 below, the Company shall pay Employee the net sum
of Three Thousand One Hundred Seventy-Five Dollars and 92/100 Dollars
($3,175.92) on or before January 25, 2000, which represents the approximate
equivalent of 12 months' payments for coverage under COBRA. It is Employee's
responsibility to pay these amounts and to obtain the appropriate coverage if
the Employee so desires.

              4.3   No additional time for vacation or sick leave or personal
time shall accrue after Termination Date. Employee's participation in the 401(k)
and, if applicable, 401(k) Wrap, and Employee Stock Purchase Plan shall cease as
of the Termination Date. Employee's participation in the Company benefit
programs for Basic Life Insurance, Accidental Death and Dismemberment Insurance
("AD&D"), Dependent Life Insurance, Short Term Disability benefits, Long Term
Disability Insurance, and any participation in the Flexible Spending Cafeteria
Plan, Voluntary Life Insurance, Voluntary AD&D, Pre-Paid Legal Insurance and
Employee Assistance Program, and all other Company programs and benefits will
terminate as of the Termination Date, subject to continuation rights, if any,
required by law. Notwithstanding the foregoing, the Company will, if Employee
requests it to do so in writing, transfer to Employee the life insurance policy
it has taken out on his life to the extent permitted by the terms of the policy.
Employee shall be solely responsible for making premium payments on such policy.

              4.4   Conditioned upon the full execution of this Agreement and
the lapse of the seven (7) day period described in Section 12 below, the Company
will fully vest all stock options granted to Employee under the Company's Stock
Option Plans that are unvested as of the Termination Date. A summary of such
unvested options and all other options granted to Employee is set forth on the
Personnel Option Status attached as Exhibit A hereto. Employee will be entitled
to exercise existing stock options for a period of six (6) months after the
Termination Date in accordance with the plans and agreements relating to such
options. Any

                                       2
<PAGE>

options not exercised prior to July 17, 2000 shall terminate and Employee shall
have no rights as to options not exercised prior to such date.

              4.5   On the first anniversary of the Termination Date, the
Company will make a determination as to whether Employee has fully complied with
all of the terms and conditions of this Agreement. If Employee has fully
complied, the Company shall pay Employee within five (5) business days of the
first anniversary of the Termination Date, the sum of Two Hundred Fifty Thousand
and 00/100 Dollars ($250,000.00), less applicable withholding taxes and other
governmental obligations.

              4.6   No other amounts except those specified in Sections 4 and 5
will be owing to or paid to Employee, including, without limitation, any bonus
payments earned or to be earned prior to or after the Termination Date.

         5.    OTHER PAYMENTS. The consideration described above in Section 4 is
separate from the payment by the Company to Employee of accrued and unused
vacation pay in the amount of Twenty-Eight Thousand Five Hundred Fifty-Nine and
01/100 Dollars ($28,559.01) and regular salary or wages for work performed
through the Termination Date, less applicable withholding taxes and other
governmental obligations ("Other Payments"). Employee's receipt of the Other
Payments is not conditioned upon signing this Agreement. Employee shall receive
all Other Payments to which Employee is entitled regardless of whether Employee
signs this Agreement.

         6.    COOPERATION CLAUSE. Upon reasonable request, the Employee shall
make himself available to the Company to furnish full and truthful information
concerning any event which took place during Employee's employment. Upon
reasonable request, as deemed necessary by the Company, the Employee shall make
himself available to the Company to furnish full and truthful consultations
concerning any potential or actual litigation. Employee shall furnish the
information as soon as is practical after a request from the Company is
received. The Company shall reimburse Employee for the reasonable cost of all
Employee's travel, lodging, meals and any loss of compensation suffered by
Employee from his current employer as a result of time spent furnishing
information under this clause.

         7.    NON-COMPETE AND NON-INTERFERENCE.

               7.1  For a period of twelve (12) months after the Termination
Date, Employee shall not, directly or indirectly, own, manage, operate, control,
be employed by, or participate in the ownership, management, operation or
control of, a business that is engaged in the same business as the Company

time Employee's employment is terminated, a Relevant Area. A "Relevant Area"
shall be defined for the purposes of this Agreement as any area located within,
or within fifty (50) miles of, the legal boundaries or limits of any city within

purposes of this Agreement, "constructive dismissal" includes, without limiting
the generality of any action by the Company which constitutes constructive
dismissal, unless consented to by Employee in writing, any of the following
actions by the Company:

          (i)   any material reduction in Employee's positions, duties,
                responsibilities, powers or reporting relationships;

          (ii)  any reduction in the annual salary of Employee;

          (iii) any requirement to relocate to another city, state or country;
                and

          (iv)  any material reduction in the value of Employee's benefits plans
                and programs, including, without limiting the generality of the
                foregoing, bonus arrangements.

          5.5   The Company may terminate this Agreement immediately for gross
negligence, intentional misconduct or the commission of a felony by the
Employee, in which case all rights under this Agreement shall end as of the date
of such termination.

          5.6   If this Agreement is terminated by the Company under Section 4
or Section 5.3, the Company shall pay Employee a termination fee in an amount
equal to the aggregate amount of her annual base salary plus her targeted annual
bonus. Such termination fee will be paid in a lump sum within fifteen (15) days
from the date of termination. If this Agreement is terminated by Employee under
Section 5.4, the Company will pay Employee a termination fee equal to the
aggregate amount of her annual base salary plus her targeted annual bonus. Such
termination fee will be paid in a lump sum within fifteen (15) days from the
date of termination. In addition, if the Company terminates this Agreement under
Section 4 or Employee terminates this Agreement under Section 5.4, all options
to purchase shares of the Company that have been granted to Employee pursuant to
the Company's long-term incentive plans, but not yet vested, will immediately
vest on the date of termination and Employee will be entitled to exercise such
options after the date of termination in accordance with the plans and
agreements relating to such options. If the terms of this Section 5.6 and the
terms of the plans and/or agreements relating to such stock options conflict,
the terms of the option plans and/or agreements shall control.

provisions herein, Employee or her legal representative shall deliver to the
Company all originals and all duplicates and/or copies of all documents,
