business plan; (ii) take away or interfere or attempt to interfere with any
custom, trade, business, patronage or other business relation of the Company, or
induce, or attempt to induce, any employees, agents or consultants of or to the
Company Group to do anything from which Executive is restricted by reason of
this Section 5; or (iii) induce or aid others to induce employees, agents or
consultants of the Company Group to terminate their employment with the Company
Group, or interfere or attempt to interfere with any employees, agents or
consultants of the Company Group.

                  5.04     EXTENSION OF RESTRICTED PERIOD. The Restricted Period
shall be extended by the length of any period during which Executive is in
breach of any of the terms of Section 5 hereof.

                  5.05     ASSIGNMENT OF DEVELOPMENTS. During the Term, all
Developments that are at any time made, conceived or suggested by Executive,
whether acting alone or in conjunction with others, shall be the sole and
absolute property of the Company, free of any reserved or other rights of any
kind on Executive's part. During the Term, if such Developments were made,

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, or of
Executive's right and title, if any, to such Developments. Executive
acknowledges and agrees that any invention, concept, design or discovery that
concretely relates to or is associated with

<PAGE>

Executive's work for the Company that is described in a patent application or is
disclosed to a third party directly or indirectly by Executive during the

disclosure by patent application or otherwise shall constitute a breach of
Section 5.01 above.

                  5.06     APPLICATION OF COVENANTS. The activities described in
this Section 5 shall be prohibited regardless of whether undertaken by Executive

partnership, firm, corporation or other business organization (other than the
Company Group).

                  5.07     INJUNCTIVE RELIEF. Without limiting the remedies
available to the Company, Executive acknowledges that a breach of any of the
covenants contained in this Section 5 may result in material irreparable injury
to the Company for which there is no adequate remedy at law, that it will not be
possible to measure damages for such injuries precisely and that, in the event
of such a breach or threat thereof, the Company shall be entitled to seek a
temporary restraining order or a preliminary or permanent injunction restraining
Executive from engaging in activities prohibited by this Section 5 or such other
relief as may be required to specifically enforce any of the covenants in this
Section 5.

                  5.08     REASONABLENESS OF COVENANTS. If, at the time of
enforcement of the covenants set forth in this Section 5, a court holds that the
restrictions stated herein are unreasonable under circumstances then existing,

reasonable under such circumstances shall be substituted for the stated period,
scope or area.

                  5.09     VIOLATION AND REMEDY. If the Company reasonably
determines that Executive has breached any of the provisions of this Section 5,
in addition to any other remedies available to the Company in law or equity, the
Company shall be entitled to immediately suspend as of the date of such breach
the provision to Executive of any payments or benefits under this Agreement,
including without limitation, the Severance Benefit outlined in Section 4 of
this Agreement, and any Severance Benefits already paid shall be immediately
returned to the Company. In addition, should the Company breach any of its
obligations under this Agreement, including without limitation, the Severance

Cause.

                  9.02     EXECUTIVE'S REPRESENTATION. Executive hereby
represents and warrants to the Company that the execution and delivery by
Executive of this Agreement to the Company will not breach the terms of any
contract, agreement or understanding to which Executive is party. Executive

                  9.03     SUCCESSORS. This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the parties hereto and their
respective heirs, legal representatives, successors and, in the case of the
Company, business successors (whether direct

<PAGE>

or indirect, by purchase, merger, consolidation or otherwise), but no other

and the obligations of Executive under this Agreement may not be assigned or
delegated.

                  9.04     SEVERABILITY. Whenever possible, each provision of
this Agreement will be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement is held to be
invalid, illegal or unenforceable in any respect under any applicable law or
rule in any jurisdiction, such invalidity, illegality or unenforceability will
not affect any other provision or any other jurisdiction, but this Agreement
will be reformed, construed and enforced in such jurisdiction as if such
invalid, illegal or unenforceable provision had never been contained herein.

                  9.05     WITHHOLDING. Amounts paid to Executive's hereunder
shall be subject to all applicable federal, state and local tax withholdings.

                  9.10     ENTIRE AGREEMENT; MODIFICATION; WAIVER;
INTERPRETATION. This Agreement contains the entire agreement and understanding
between the parties with respect to the subject matter hereof and supersedes all
prior negotiations and oral understandings concerning the subject matter hereof;
provided, however, that, (1) the Indemnity Agreement dated September 20, 2002,
attached hereto as Appendix C and incorporated herein by reference, and (2)
Section 2 (entitled "Retention Bonus") of the Retention and Severance Agreement
dated October 11, 2001, attached hereto as Appendix D and incorporated herein by

supercedes the remaining terms and conditions of said Retention and Severance
Agreement; provided, however, that it is the intention of the parties hereto
that if this Agreement is void, becomes voidable, or otherwise is or becomes
unenforceable as drafted, then the Retention and Severance Agreement shall
continue in full force and effect, in accordance with the terms and conditions

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

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,

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

and regulations promulgated thereunder ("ADEA").

                  3. Release of Unknown Claims. I understand that I am releasing

succeeding business day. 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 by a representative of the Company prior
to the expiration of the Revocation Period.

                  My signature below indicates my agreement with the terms and
         provisions described above.

devote his full business time, attention and energies to the positions of
Executive Vice President and Chief Financial Officer of the Company; provided,
however, that Executive may devote reasonable amounts of time to (i) passive

denominator of which is 365.

                  3.05     BENEFITS. Executive and his eligible dependents shall

benefit (the "SEVERANCE BENEFIT") equal to two times the Fixed Salary and the

Severance Benefit shall be paid by the Company in twenty-four (24) equal monthly
installments beginning on the date that is one (1) month after the date of his
termination of employment. Payment of the Severance Benefit shall be contingent
upon Executive's execution of a waiver and release of claims in favor of the

acknowledges that in the course of Executive's employment with the Company,
Executive has become familiar, and will become familiar, with the trade secrets
of the Company Group and with other confidential information concerning the

unique and extraordinary value to the Company Group. Therefore, Executive hereby
agrees that for the duration of the Restricted Period, Executive shall not,
unless Executive receives the prior written consent of the Board of Directors of
the Company (the "BOARD"), directly or indirectly, knowingly own an interest in,
manage, operate, join, control, lend money or render financial or other
assistance to or participate in or be connected with, as an officer, employee,
partner, stockholder, consultant or otherwise, any individual, partnership,
firm, corporation or other business organization or entity that competes with
the business of the Company as such businesses exist or are in the process of
being formed or acquired as of the Termination Date, within any geographical

Company, or that to Executive's knowledge is contemplated from time to time
during the period of Executive's employment with the Company by the Company's
business plan; (ii) take away or interfere or attempt to interfere with any
custom, trade, business, patronage or other business relation of the Company, or
induce, or attempt to induce, any employees, agents or consultants of or to the
Company Group to do anything from which Executive is restricted by reason of
this Section 5; or (iii) induce or aid others to induce employees, agents or
consultants of the Company Group to terminate their employment with the Company
Group, or interfere or attempt to interfere with any employees, agents or
consultants of the Company Group.

                  5.04     EXTENSION OF RESTRICTED PERIOD. The Restricted Period

<PAGE>

                  5.05     ASSIGNMENT OF DEVELOPMENTS. During the Term, all
Developments that are at any time made, conceived or suggested by Executive,
whether acting alone or in conjunction with others, shall be the sole and
absolute property of the Company, free of any reserved or other rights of any
kind on Executive's part. During the Term, if such Developments were made,
conceived or suggested by Executive during or as a result of Executive's
employment relationship with the Company, thereafter, Executive shall promptly
make full disclosure of any such Developments to the Company and, at the
Company's cost and expense, do all acts and things (including, among others, 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, or of
Executive's right and title, if any, to such Developments. Executive
acknowledges and agrees that any invention, concept, design or discovery that
concretely relates to or is associated with Executive's work for the Company
that is described in a patent application or is disclosed to a third party
directly or indirectly by Executive during the Restricted Period shall be the
property of and owned by the Company and such disclosure by patent application
or otherwise shall constitute a breach of Section 5.01 above.

                  5.06     APPLICATION OF COVENANTS. The activities described in
this Section 5 shall be prohibited regardless of whether undertaken by Executive
in an individual or representative capacity, and regardless of whether performed

partnership, firm, corporation or other business organization (other than the
Company Group).

                  5.07     INJUNCTIVE RELIEF. Without limiting the remedies
available to the Company, Executive acknowledges that a breach of any of the
covenants contained in this Section 5 may result in material irreparable injury
to the Company for which there is no adequate remedy at law, that it will not be
possible to measure damages for such injuries precisely and that, in the event
of such a breach or threat thereof, the Company shall be entitled to seek a
temporary restraining order or a preliminary or permanent injunction restraining
Executive from engaging in activities prohibited by this Section 5 or such other
relief as may be required to specifically enforce any of the covenants in this
Section 5.

                  5.08     REASONABLENESS OF COVENANTS. If, at the time of
enforcement of the covenants set forth in this Section 5, a court holds that the
restrictions stated herein are unreasonable under circumstances then existing,
the parties hereto agree that the maximum period, scope or geographical area
reasonable under such circumstances shall be substituted for the stated period,
scope or area.

                  5.09     VIOLATION AND REMEDY. If the Company reasonably
determines that Executive has breached any of the provisions of this Section 5,
in addition to any other remedies available to the Company in law or equity, the
Company shall be entitled to immediately suspend as of the date of such breach
the provision to Executive of any payments or benefits under this Agreement,
including without limitation, the Severance Benefit outlined in Section 4 of
this Agreement, and any Severance Benefits already paid shall be immediately
returned to the Company. In addition, should the Company breach any of its
obligations under this Agreement, including without limitation, the Severance
Benefit outlined in Section 4, Executive will not be bound by the provisions of
Sections 5.02 and 5.03.

controversy or claim between the parties arising from or relating to this
Agreement, its breach or any matter addressed by the Agreement shall be resolved
through binding confidential arbitration in Rochester, New York, to be conducted
by an arbitrator that is mutually agreeable to both Executive and the Company,
all in accordance with the rules of the American Arbitration Association then in
effect. If Executive and the Company cannot agree upon an arbitrator, the
arbitration shall be settled before a panel of three arbitrators, one to be
selected by the Company, one by Executive and the other by the two persons so
selected, all in accordance with the rules of the American Arbitration
Association then in effect. Judgment upon the award rendered by the
arbitrator(s) may be entered by any court having jurisdiction over the matter.
Costs and fees of the arbitration will be divided equitably by the arbitrator
between both parties; provided, however, that, in the event that either party
prevails over the other party in connection with an arbitration arising out of a
breach of this Agreement, the non-prevailing party shall be liable for all
reasonable attorney's fees and expenses incurred in connection with any action
for damages or the enforcement of any provision of this Agreement brought by the
other party.

                  9.       MISCELLANEOUS.

                  9.01     NO RIGHTS TO CONTINUED EMPLOYMENT. Neither this
Agreement nor any of the rights or benefits evidenced hereby shall confer upon
Executive any right to continuance of employment by the Company or interfere in
any way with the right of the Company to terminate Executive's employment,
subject to the provisions of Section 4 above, for any reason, with or without
Cause.

                  9.02     EXECUTIVE'S REPRESENTATION. Executive hereby
represent and warrant to the Company that the execution and delivery by
Executive of this Agreement to the Company will not breach the terms of any
contract, agreement or understanding to which Executive is party. Executive
further acknowledges and agrees that a breach of this representation by
Executive shall render this Agreement void ab initio and of no further force and
effect.

                  9.03     SUCCESSORS. This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the parties hereto and their
respective heirs, legal representatives, successors and, in the case of the
Company, business successors (whether direct or indirect, by purchase, merger,
consolidation or otherwise), but no other person shall acquire or have any
rights under or by virtue of this Agreement, and the obligations of Executive
under this Agreement may not be assigned or delegated.

                  9.04.    SEVERABILITY. Whenever possible, each provision of
this Agreement will be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement is held to be
invalid, illegal or unenforceable in any respect under any applicable law or
rule in any jurisdiction, such invalidity, illegality or unenforceability will
not affect any other provision or any other jurisdiction, but this Agreement
will be reformed, construed and enforced in such jurisdiction as if such
invalid, illegal or unenforceable provision had never been contained herein.

                  9.05     WITHHOLDING. Amounts paid to Executive's hereunder
shall be subject to all applicable federal, state and local tax withholdings.

                  9.06     HEADINGS. The headings contained in this Agreement
are intended solely for convenience of reference and shall not affect the rights
of the parties to this Agreement.

                  9.07     SURVIVAL. All of the provisions and restrictions set
forth in Section 5 shall survive and continue in full force in accordance with
their terms notwithstanding any termination of the Term.

                  9.08     COUNTERPARTS. This Agreement may be executed in
separate counterparts, each of which is deemed to be an original and all of
which taken together constitute one and the same agreement.

                  9.09     GOVERNING LAW. This Agreement shall be governed by
and construed and enforced in accordance with the laws and decisions of the

without giving effect to the principles of conflict of laws.

                  9.10     ENTIRE AGREEMENT; MODIFICATION; WAIVER;
INTERPRETATION. This Agreement contains the entire agreement and understanding
between the parties with respect to the subject matter hereof and supersedes all
prior negotiations and oral understandings concerning the subject matter hereof;
provided, however, (1) the Indemnity Agreement dated July 15, 2002, attached
hereto as Appendix C and incorporated herein by reference, shall be enforceable
and binding on the parties; and (2) Section 2 (entitled "Retention Bonus") of
the Retention and Severance Agreement dated October 11, 2001, attached hereto as
Appendix D and incorporated herein by reference, shall be enforceable and
binding on the parties. This Agreement supercedes the remaining terms and
conditions of said Retention and Severance Agreement. Neither this Agreement nor
any of its provisions may be modified, amended, waived, discharged or
terminated, in whole or in part, except in writing signed by the party to be
charged. No waiver of any such provision or any breach of or default under this
Agreement shall be deemed or shall constitute a waiver of any other provision,
breach or default. All pronouns and words used in this Agreement shall be read
in the appropriate number and gender, the masculine, feminine and neuter shall
be interpreted interchangeably and the singular shall include the plural and
vice versa, as the circumstances may require.

Mpower Communications Corp.
175 Sully's Trail, Suite 300
Pittsford, NY 14534

                                     RELEASE

                  I, S. Gregory Clevenger, am a party to an Employment Agreement
(the "AGREEMENT"), dated April 25, 2002, 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 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;
PROVIDED, HOWEVER, that notwithstanding anything to the contrary in this
Release, the rights and obligations established by the Indemnity Agreement dated
July 15, 2002 shall be enforceable and binding on the Released Parties.

                  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
assigns.

                  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.

                                      A-1

<PAGE>

                  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.

                  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.

                  1.7. Revocation. I have the right to revoke this Release
during the seven-day period (the "REVOCATION PERIOD") commencing immediately
following the date I sign and deliver this Release to the Company. The
Revocation Period shall expire at 5:00 p.m., New York time, on the last day of
the Revocation Period; PROVIDED, HOWEVER, that if such seventh day is not a
business day, the Revocation Period shall extend to 5:00 p.m. on the next
succeeding business day. 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 by a representative of the Company prior
to the expiration of the Revocation Period.

         My signature below indicates my agreement with the terms and provisions
described above.
