                     THIRD AMENDMENT TO EMPLOYMENT AGREEMENT

This is the third amendment (the "Third Amended Agreement") to that certain
Amended Employment Agreement dated as of the 8th day of August, 2000 (the
"Agreement"), the First Amended Agreement dated as of September 20, 2002 (the
"First Amended Agreement"), and the Second Amended Agreement dated as of March
19, 2003 (the "Second Amended Agreement") between Mpower Communications Corp., a
Nevada corporation (the "Company") and Joseph M. Wetzel ("Executive").

The Company and Executive, for and in consideration of the promises, terms and
conditions contained herein, do hereby agree to make the following amendments to
the Agreement.

1. Section 1(a) of the First Amended Agreement is deleted in its entirety and
replaced by the following:

"EMPLOYMENT TERM. Subject to earlier termination in accordance with the
provisions of this Agreement, the Agreement shall become effective as of the
date hereof (the "EFFECTIVE DATE") and the term of Executive's employment with
the Company pursuant to this Agreement (the "TERM") shall continue until either
party terminates Executive's employment, subject to Executive's rights and the
Company's obligations contained in Section 4 of this Agreement."

2. Section 2(b) of the First Amended Agreement, as amended by the Second Amended
Agreement, is hereby deleted in its entirety and replaced by the following:

"4.02 TERMINATION WITHOUT CAUSE; RESIGNATION FOR GOOD REASON. In the event of
(A) the Company's termination of Executive's employment hereunder without Cause,
(B) Executive's resignation for Good Reason, (C) Executive's death, or (D)
Executive's Disability, he shall be entitled to the following: (i) the payments
and benefits described immediately above in sub-section (a) and (ii) a severance
benefit (the "SEVERANCE BENEFIT") equal to two times (a) the higher of the Fixed
Salary paid immediately preceding the Termination Date or the Fixed Salary on
March 18, 2003 and (b) the "HIGHEST BONUS", where the Highest Bonus equals the
greater of the Annual Bonus paid by the Company to Executive (x) during the
period from twelve (12) months immediately preceding the Effective Date through
the Termination Date, or (y) if the reduction in Executive's Fixed Salary is not
restored in whole or part, the amount the Annual Bonus would have been from the
date of this Agreement through the Termination Date, calculated as if all
reductions had been restored, but only to the extent that any such Annual Bonus
paid during this period utilized the amount of Executive's Fixed Salary in
calculating said Annual Bonus; provided, however, that Executive shall have no
right to have paid or payable from the Trust adopted by Company on October 23,
2001 pursuant to a Trust Agreement with HSBC Bank USA as trustee (the "OLD
TRUST"), any portion of the Severance Benefit (i) attributable to any increase
in his Fixed Salary after March 31, 2002, or (ii) otherwise in excess of the
Severance Benefit or other severance payment that Executive would have been
eligible to receive if his employment with the Company had terminated as of
March 31, 2002 under circumstances entitling him to a Severance Benefit or other
severance payment. Payment of the Severance Benefit shall be contingent upon
Executive's execution of a waiver and release of claims (a "RELEASE") in favor
of the Company and its affiliates and their respective employees and agents,
substantially in the form set forth in Appendix A. The Severance Benefit shall
be paid by the Company in a lump sum, no later than two (2) business days after
the expiration of the Revocation Period, as defined in the Release."

3. Section 2(c) of the First Amended Agreement is hereby deleted in its
entirety, and replaced by the following:

"TERMINATION DUE TO DEATH OR DISABILITY. In the event of Executive's death or
Disability, the Fixed Salary shall immediately cease. Neither Executive, nor his
estate, as the case may be, shall be entitled to continue to receive any
benefits other than the Severance Benefit, proceeds from insurance per the terms
of any applicable policy and reimbursement of expenses. In addition, all further
vesting of options shall cease on the Termination Date."

                    FOURTH AMENDMENT TO EMPLOYMENT AGREEMENT

This is the fourth amendment (the "Fourth Amended Agreement") to that certain
Amended Employment Agreement dated as of the 8th day of August, 2000 (the
"Agreement"), the First Amended Agreement dated as of September 20, 2002 (the
"First Amended Agreement"), the Second Amended Agreement dated as of March 19,
2003 (the "Second Amended Agreement"), and the Third Amended Agreement dated as
of June, 2003 (the "Third Amended Agreement") between Mpower Communications
Corp., a Nevada corporation (the "Company") and Joseph M. Wetzel ("Executive")
(collectively, the "Agreements").

The Company and Executive, for and in consideration of the promises, terms and
conditions contained herein, do hereby agree to make the following amendments to
the Agreements.

1. Notwithstanding anything contained in the Agreements to the contrary, the
Company shall pay to the Executive, on or before December 31, 2003, the amount
of $14,405.63, less customary withholdings, representing all income taxes the
Executive will have to pay on any relocation/housing/travel monies paid by the
Company to the Executive for both himself and his wife, Sharon Wetzel, in 2003.
Adjustments will be made immediately if in fact the taxes paid are greater or
less than $14,405.63.

2. Notwithstanding anything contained in the Agreements to the contrary, the
Company shall pay to the Executive an additional sum of $15,735.64, less
customary withholdings, representing reimbursement to the Executive for any and
all expenses related to his rental residence in Las Vegas, Nevada through the
expiration of his present lease, with the parties recognizing that this sum has
already been grossed up for taxes. Adjustments will be made immediately if in
fact the taxes paid are greater or less than $5,735.64.

3. Notwithstanding anything contained in the Agreements to the contrary, the
parties agree that except as set forth herein, and pursuant to the Company's
existing reimbursement policies with respect to the Executive's travel in the
ordinary course of business, no additional amounts will be paid to the Executive
in 2004 for either his travel or the travel of his wife, Sharon Scott.

4. At the expiration of his present lease of his rental residence, the security
deposit of $2,000, less any deductions made by the landlord, shall be returned
to the Company.

5. Notwithstanding anything contained in the Agreements to the contrary, in the
event the Executive purchases a residence in Las Vegas, Nevada when his lease
expires, the Company shall pay all closing costs with respect to the purchase of
that property, and all reasonable and customary moving expenses with respect to
any furniture or other personal belongings moved by the Executive at that time
from Denver, Colorado to Las Vegas, Nevada. The parties agree that this
provision is in lieu of all other rights the Executive has with respect to any
and all Company relocation policies presently in effect.

6. Notwithstanding anything contained in the Agreements to the contrary, if the
Executive's employment with the Company is terminated pursuant to 4.02 of the
Third Amended Agreement, and a result of that termination of employment, the
Executive notifies the Company within six (6) months of the termination that the
residential property referred to in paragraph 5 above has been listed for sale,
the Company will pay reasonable closing costs with respect to any such sale
completed pursuant to that initial listing or any subsequent but continuous
listing at commercially reasonable offering prices. The parties agree that this
provision is in lieu of all other rights the Executive has with respect to any
and all Company relocation policies presently in effect as regards a sale
resulting from a termination pursuant to 4.02. The Company's customary
relocation policies shall apply to any other move made by the Executive from Las
Vegas agreed to by all parties.

7. Notwithstanding anything contained in the Agreements to the contrary, the
Executive unequivocally waives his right to assert that his business or
residential relocation to Las Vegas, Nevada triggered any rights under any
existing agreement between the Company and the Executive, including but not
limited to the aforesaid Agreements and any and all stock option agreements
presently in existence between the Company and the Executive.
