executors, administrators, successors, heirs, distributees, devisees and
legatees. If you should die while any amount would still be payable to you
hereunder if you had continued to live, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Agreement to
your devisee, legatee or other designee or, if there is no such designee, to
your estate.

            7. PROTECTION OF THE COMPANY'S INTERESTS.

Company, or otherwise interfere with the relationship of the Company with, any
person or entity who is, or was within the then most recent twelve-month period,
(A) employed by, or otherwise engaged to perform services for, the Company, or
(B) a customer or client of the Company or (ii) otherwise interfere with the
business of the Company.

during the period beginning on the date hereof and continuing in perpetuity
thereafter, you shall keep confidential and shall not directly or indirectly
disclose any such Proprietary Information to any third party, except as required
to fulfill your duties in connection with your employment by the Company, and
shall not misuse, misappropriate or exploit such Proprietary Information in any
way. The restrictions contained herein shall not apply to any information which
you can demonstrate (i) was already available to the public at the time of
disclosure, or subsequently became available to the public, otherwise than by

the execution and delivery under oath of patent and copyright applications and
instruments of assignment) deemed by the Company to be necessary or desirable at
any time in order to effect the full assignment to the Company, of your right
and title, if any, to such Developments. You acknowledge and agree that any
invention, concept, design or discovery that concretely relates to or is
associated with your work for the Company that is described in a patent
application or is disclosed to a third party directly or indirectly by you

                                     RELEASE

            I, Michele D Sadwick, am a party to a Retention Agreement (the
"AGREEMENT"), dated October 11, 2001, with Mpower Communications Corp., a Nevada
corporation (the "COMPANY"). The Agreement contemplates that, in consideration
for my receipt of the Severance Benefit (as such term is defined in the
Agreement), I will deliver a Release in the form set forth below, and I now
desire to deliver such Release to the Company in the manner contemplated by the
Agreement.

            1. General Release. In consideration of the Severance Benefit, I
hereby release and forever discharge the Released Parties (as defined below)
from any and all claims, actions, causes of action, suits, costs controversies,
judgments, decrees, verdicts, damages, liabilities, attorney's fees, covenants,
contracts and agreements (collectively, including claims, actions and causes of
action set forth in Section 2 below, "CLAIMS") that I may have against the
Released Parties based on or arising out of (i) my employment relationship with
and service as an employee, officer or director of the Company, and the
termination of such relationship or service, or (ii) any event, condition,
circumstance or obligation that occurred, existed or arose on or prior to the
date hereof, including, without limitation, any Claims arising under any
applicable federal, state or local law, or any law of any foreign jurisdiction,
whether such Claim arises under statute, common law or in equity, and whether or
not I am presently aware of such claim. I further agree that the payments and
benefits described in the Agreement are in full satisfaction of any and all
Claims for payments or benefits that I may have against the Company arising out
of my employment relationship, my service as an employee, officer or director of
the Company and the termination thereof. I also do forever release, discharge
and waive any rights that I may have to recover in any proceedings brought by
any federal, state or local agency against the Released Parties to enforce any
laws.

            For purposes of this release, the "RELEASED PARTIES" means,
individually and collectively, the Company, its present, former and future
shareholders, partners, limited partners, affiliates, parents, subsidiaries,
successors, directors, officers, employees, agents, attorneys, successors and

            2. Specific Release of ADEA Claims. In further consideration of the
Severance Benefit, I hereby release and forever discharge the Company and its
employees, officers and directors from any and all Claims that I may have as of
the date of my signing of this Release arising under the FEDERAL AGE
DISCRIMINATION IN EMPLOYMENT ACT OF 1967, AS AMENDED, and the applicable rules
and regulations promulgated thereunder ("ADEA").

            3. Release of Unknown Claims. I understand that I am releasing
Claims pursuant to this Agreement that I may not know about, and that is my
intent. I expressly waive all rights that I might have under any law that is
intended to prevent unknown Claims from being released and I understand the
significance of doing so. In addition, I expressly acknowledge that the Release
under this Agreement is intended to include and does include in its effect,
without limitation, all Claims which I do not know or suspect to exist in my
favor at the time of execution of this Release and that this Release expressly
contemplates the extinguishment of all such Claims.

            4. No Pending Litigation. I hereby represent and agree that I have
not filed, and will not file, any action, complaint, charge, grievance or
arbitration against any Released Party.

            5. No Right to Commence any Legal Action. I will not commence or
join any legal action, which term includes, without limitation, any demand for
arbitration proceedings and any complaint to any federal, state or local agency,
court or other tribunal, to assert any Claim released by me under this Agreement
against a Released Party. If I commence or join any such legal action against a
Released Party, I will promptly indemnify such
<PAGE>
Released Party for its reasonable costs and attorneys' fees incurred in
defending such action as well as any monetary judgment obtained by me against
any Released Party in such action.

            6. Acknowledgment. By signing this Release, I hereby acknowledge and
confirm the following:

            (a) Consultation with an Attorney. I was advised in writing by the
     Company in connection with my termination of employment to consult with an
     attorney of my choice prior to signing the Agreement and this Release and
     to have such attorney explain to me the terms of the Agreement and this
     Release, including, without limitation, the terms relating to my release of
     claims arising under ADEA.

            (b) Understand this Agreement. I have read the Agreement and this
     Release carefully and completely and understand each of the terms thereof.

            (c) Twenty-One Days to Consider. I was given not less than
     twenty-one days to consider the terms of the Agreement and this Release and
     to consult with an attorney of my choosing with respect thereto, and that
     for a period of seven days following my signing of this Release, I have the
     option to revoke this Release in accordance with the terms set forth below.

            (d) Consideration. By signing this Release, I hereby acknowledge and
     confirm that I am providing the Release and discharge set forth herein only
     in exchange for consideration in addition to anything of value to which I
     am already entitled.

            7. Revocation. I have the right to revoke this Release during the

In the event of any such revocation by me, the obligations of the Company to pay
the Severance Benefit pursuant to the Agreement shall terminate and be of no
further force and effect as of the date of such revocation. No such revocation
by me shall be effective unless it is in writing and signed by me and received

                                     RELEASE

            I, Roger J Pachuta, am a party to a Severance Agreement (the
"AGREEMENT"), dated October 10, 2001, with Mpower Communications Corp., a Nevada
corporation (the "COMPANY"). The Agreement contemplates that, in consideration
for my receipt of the Severance Benefit (as such term is defined in the
Agreement), I will deliver a Release in the form set forth below, and I now
desire to deliver such Release to the Company in the manner contemplated by the
Agreement.

            1. General Release. In consideration of the Severance Benefit, I
hereby release and forever discharge the Released Parties (as defined below)
from any and all claims, actions, causes of action, suits, costs controversies,
judgments, decrees, verdicts, damages, liabilities, attorney's fees, covenants,
contracts and agreements (collectively, including claims, actions and causes of
action set forth in Section 2 below, "CLAIMS") that I may have against the
Released Parties based on or arising out of (i) my employment relationship with
and service as an employee, officer or director of the Company, and the
termination of such relationship or service, or (ii) any event, condition,
circumstance or obligation that occurred, existed or arose on or prior to the
date hereof, including, without limitation, any Claims arising under any
applicable federal, state or local law, or any law of any foreign jurisdiction,
whether such Claim arises under statute, common law or in equity, and whether or
not I am presently aware of such claim. I further agree that the payments and
benefits described in the Agreement are in full satisfaction of any and all
Claims for payments or benefits that I may have against the Company arising out
of my employment relationship, my service as an employee, officer or director of
the Company and the termination thereof. I also do forever release, discharge
and waive any rights that I may have to recover in any proceedings brought by
any federal stat or local agency against the Released Parties to enforce any
laws.

            For purposes of this release, the "RELEASED PARTIES" means,

            2. Specific Release of ADEA Claims. In further consideration of the
Severance Benefit, I hereby release and forever discharge the Company and its

the date of my signing of this Release arising under the FEDERAL AGE
DISCRIMINATION IN EMPLOYMENT ACT OF 1967, AS AMENDED, and the applicable rules
and regulations promulgated thereunder ("ADEA").

            3. Release of Unknown Claims. I understand that I am releasing
Claims pursuant to this Agreement that I may not know about, and that is my
intent. I expressly waive all rights that I might have under any law that is
intended to prevent unknown Claims from being released and I understand the
significance of doing so. In addition, I expressly acknowledge that the Release
under this Agreement is intended to include and does include in its effect,
without limitation, all Claims which I do not know or suspect to exist in my
favor at the time of execution of this Release and that this Release expressly
contemplates the extinguishment of all such Claims.

            4. No Pending Litigation. I hereby represent and agree that I have
not filed, and will not file, any action, complaint, charge, grievance or
arbitration against any Released Party.

            5. No Right to Commence any Legal Action. I will not commence or
join any legal action, which term includes, without limitation, any demand for
arbitration proceedings and any complaint to any federal, state or local agency,
court or other tribunal, to assert any Claim released by me under this Agreement
against a Released Party. If I commence or join any such legal action against a
Released Party, I will promptly indemnify such
<PAGE>
Released Party for its reasonable costs and attorneys' fees incurred in
defending such action as well as any monetary judgment obtained by me against
any Released Party in such action.

            6. Acknowledgment. By signing this Release, I hereby acknowledge and
confirm the following:

            (a) Consultation with an Attorney. I was advised in writing by the

     to have such attorney explain to me the terms of the Agreement and this
     Release, including, without limitation, the terms relating to my release of

     to consult with an attorney of my choosing with respect thereto, and that
     for a period of seven days following my signing of this Release, I have the
     option to revoke this Release in accordance with the terms set forth below.

            (d) Consideration. By signing this Release, I hereby acknowledge and
     confirm that I am providing the Release and discharge set forth herein only
     in exchange for consideration in addition to anything of value to which I

further force and effect as of the date of such revocation. No such revocation
