                           to Asset Purchase Agreement
                                 PROMISSORY NOTE
                                  U.S. $400,000

FOR VALUE RECEIVED, ERF Wireless, Inc., a Nevada corporation, ("Maker"), hereby
promises to pay to SkyvueUSA East Central Texas, Inc. ("Payee" or "Holder") the
principal sum of Four Hundred Thousand Dollars ($400,000) plus interest at the
rate of six percent (6%) per annum on the unpaid balance. This Secured
Promissory Note ("Note") shall be repaid by the maker in quarterly installments
of principal and interests totaling $43,175.06 commencing on _________________,
2005 and continuing the first day of each calendar quarter thereafter until the
entire outstanding balance has been repaid with cash or Freely Tradable shares
of Maker's common stock, as set forth below. The Note shall be secured by 100%
of the issued and outstanding capital stock of ERF Enterprise Network Services,
Inc., a Texas corporation and a newly formed subsidiary of Maker organized for
the purpose of purchasing substantially all of the assets of Payee, under a
Pledge Agreement executed concurrent with this Note. The Maker may prepay the
Note at any time. Furthermore, the Maker has made certain affirmative principal
reduction covenants based upon future events, as set forth below. "Freely
Tradable stock" shall mean fully registered securities which are not subject to
any contractual, regulatory or other legal restrictions on their transfer, are
free and clear of all liens and encumbrances and are freely tradable to members
of the general public.

This Note was delivered as partial consideration for the Purchase Price under an
Asset Purchase Agreement between Maker and Holder dated August 8, 2005.
Accordingly, $25,000 of the quarterly payments on the Note shall be subject to
offset by Maker (if consented to in writing by Seller Representative, such
consent not to be unreasonably withheld or delayed) to address any post-closing
Purchase Price adjustments and potential indemnification claims provided in
writing to Seller.

All documents and instruments now or hereafter evidencing and/or securing the
indebtedness evidenced hereby or any part thereof, including but not limited to
this Note and the Pledge Agreement of even date, are sometimes collectively
referred to herein as the "Security Documents."

USURY SAVING CLAUSE. All agreements in this Note and all other Security
Documents are expressly limited so that in no contingency or event whatsoever,
whether by reason of acceleration of maturity of the indebtedness evidenced
hereby or otherwise, shall the amount agreed to be paid hereunder for the use,
forbearance or detention of money exceed the highest lawful rate permitted under
applicable usury laws. If, for any circumstance whatsoever, fulfillment of any
provision of this Note or any other Security Document at the time performance of
such provision shall be due shall involve exceeding any usury limit prescribed
by law which a court of competent jurisdiction may deem applicable hereto, then,
IPSO FACTO, the obligations to be fulfilled shall be reduced to allow compliance
with such limit, and if, from any circumstance whatsoever, Payee shall ever
receive as interest an amount which would exceed the highest lawful rate, the

                                      -1-
<PAGE>

receipt of such excess shall be deemed a mistake and shall be canceled
automatically or, if theretofore paid, such excess shall be credited against the
principal amount of the indebtedness evidenced hereby to which the same may
lawfully be credited, and any portion of such excess not capable of being so
credited shall be refunded immediately to Maker.

COLLATERAL CLAUSE. To secure the payment of this Note, Maker hereby grants to
the Holder pursuant to a Pledge Agreement dated of even date between Maker and
Holder a security interest in certain investment securities that shall consist
of not less than all of the issued and outstanding shares of the capital stock
of ERF Enterprise Network Services, Inc., a Texas corporation (the "Collateral")
that are owned by and registered in the name of Maker.

PAYMENT IN SHARES INSTEAD OF CASH. Provided a registration statement has been
declared effective covering not less than 200,000 shares of Maker's $.001 par
value common stock underlying this Note, the Maker can deliver its shares in
lieu of cash for any quarterly payment obligation to the Holder of the Note.
Maker agreed to file a registration statement at its own expense covering shares
of its common stock to allow Maker the option of using its stock in lieu of cash
for any quarterly payments due on the Note. In this regard, Maker guarantees the
Holder that the underlying value of the common stock used to discharge any
quarterly payment shall maintain or exceed the cash value of the quarterly
payment for a period of 60 days from the payment date. Otherwise, Maker shall
promptly deliver additional shares or cash for any difference between the value
of the common stock delivered as a quarterly payment and the value of said
shares 60 days thereafter. Valuation of the shares shall be based upon the same
method and will initially be based upon the average of the closing bid and ask
price of Maker's common stock on the OTCBB as quoted under the symbol "ERFW."
Any common stock delivered to Holder as a quarterly payment shall be fully
registered securities that are not subject to any contractual, regulatory, or
other legal restrictions on their transfer, are free and clear of all liens and
encumbrances and are freely tradable to members of the general public.

AFFIRMATIVE COVENANTS BASED ON FUTURE EVENTS. Notwithstanding the payments terms
set forth above, Maker agrees to make accelerated payments to discharge the Note
based upon the occurrence of future events. In this regard, Maker agrees to
prepay the Note in the event that the Holder or its designated representatives
causes to be closed and made available to the Maker at least $1,000,000 in
proceeds from the Maker's securities offering pursuant to its Private Placement
Memorandum, ("PPM"), dated June 25, 2005 or as hereafter modified. In the event
that the Holder or its designated representatives close less than $1,000,000
against Maker's PPM; then the Maker will be obligated to prepay the Note at the
rate of $1.00 in principal reduction for every $2.00 in funds received by Maker
from the efforts of the Holder or its designated representatives in securing
funds for Maker under the PPM.

DEFAULT. Upon default, the Holder may resort to any remedy, including immediate
sale of the Collateral, available to a secured party under the Uniform
Commercial Code. Each of the following events or occurrences shall constitute an
"Event of Default" hereunder: (a) if default is made in the payment of any
monetary amount payable hereunder or under the terms of any Security Document,
within ten (10) business days following the date the same is due; (b) if default
is made in the performance of any other promise or obligation described herein,
in any Security Document, or in any other document evidencing or securing any
indebtedness of Maker to Payee following thirty (30) days prior written notice

                                      -2-
<PAGE>

to Maker of such default and the failure of Maker to cure such default within
said thirty (30) day period; (c) if Maker shall execute an assignment of any of
its property for the benefit of creditors, fail to meet any obligations herein
described, be unable to meet its debts as they mature, or be declared insolvent
by any court, suffer a receiver to be appointed for any of its property, or
voluntarily seek relief or have involuntary proceedings brought against it under
any provision now in force or hereinafter enacted of any law relating to
bankruptcy; (d) if any writ of attachment, garnishment or execution shall be
issued against Maker and not quashed within thirty (30) days; (e) if any tax
lien be assessed or filed against Maker and remain unsatisfied for forty-five
(45) days; and (f) failure to make the principal reduction payments within ten
(10) business days under the affirmative covenants based upon future events.

Upon the occurrence of any Event of Default, which is not cured within the time
set forth above after written notice of such default is given by Payee or at any
time thereafter when any Event of Default may continue, Payee may, at its option
and in its sole discretion, declare the entire balance of this Note to be
immediately due and payable, and upon such declaration all sums outstanding and
unpaid under this Note shall become and be in default, matured and immediately
due and payable, without presentment, demand, protest or notice of any kind to
Maker or any other person, all of which are hereby expressly waived, anything in
this Note or any other Security Document to the contrary notwithstanding.

WAIVER OF JURY TRIAL. Payee and Maker hereby agree to trial by court and
irrevocably agree to waive jury trial in any action or proceeding (including but
not limited to any counterclaim) arising out of or in any way related to or
connected with this Note or any other Security Document, the relationship
created thereby, or the origination, administration or enforcement of the
indebtedness evidenced and/or secured by this Note or any other Security
Document.

APPLICABLE LAW. This Note has been delivered to Payee and accepted by Payee in
the State of Texas and shall be governed and construed generally according to
the laws of said State, except to the extent that creation, validity, perfection
or enforcement of any liens or security interests securing this Note are
governed by the laws of another jurisdiction. Venue of any action brought
pursuant to this Note or any other Security Document, or relating to the
indebtedness evidenced hereby or the relationships created by or under the
Security Documents shall, at the election of the party bringing the action, be
brought in a State or United States federal court in Williamson County, Texas.
Maker and Payee each waives any objection to the jurisdiction of or venue in
such court and to the service of process issued by such court and agrees that
each may be served by any method of process described in the State of Texas or
United States Federal Rules of Civil Procedure. Maker and Payee each waive the
right to claim that such court is an inconvenient forum or any similar defense.

If, in any jurisdiction, any provision of this Note shall, for any reason, be
held to be invalid, illegal, or unenforceable in any respect, such holding shall
not affect any other provisions of this Note, and this Note shall be construed,
to the extent of such invalidity, illegality or unenforceability (and only to
such extent) as if any such provision had never been contained herein. Any such
holding of invalidity, illegality or unenforceability in one jurisdiction shall
not prevent valid enforcement of any affected provision if allowed under the
laws of another relevant jurisdiction.

No waiver by the holder of any payment or other right under this Note shall

                                  EXHIBIT 10.15

               SERIES A PREFERRED CONVERSION RESTRICTION AGREEMENT

         THIS SERIES A CONVERSION RESTRICTION AGREEMENT (the "Agreement") is
made and entered into as of the date set forth on the signature page below,
between ERF WIRELESS, INC., a Nevada corporation (the "Company"), and the holder
identified on the signature page ("Holder").

         WHEREAS, the Holder owns shares of the Company's Series A Preferred
Stock, as identified on the signature page, which are convertible into shares of
Company's common stock at the Holder's discretion;

         WHEREAS, the Holder desires to enter into this Agreement to restrict
the amount of shares of Series A Preferred Stock that can be converted provided
that contemporaneously herewith the Company shall grant Holder the Right of
First Refusal (as herein defined); and

         WHEREAS, the Holder has agreed to accept the Right of First Refusal and
to enter into this Agreement and to restrict the conversion of the shares of the
Company's Series A Preferred Stock, all on the terms set forth below.

         NOW, THEREFORE, in consideration of the foregoing premises and the
mutual covenants contained herein, and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

         1. Each Holder agrees to restrict the amount of Series A Preferred
Stock that can be converted into common stock of the Company per calendar
quarter to an amount equal to the lesser of (i) 5% of their shares of the
Company's Series A Preferred Stock or (ii) 1% of the common stock then
outstanding determined on the first day of the calendar quarter. Amounts
remaining unconverted by one Holder may be assigned to another Holder as long as
the group doesn't exceed this limitation. The Holder acknowledges that the
certificates issued upon the conversion of the Series A Preferred Stock into the
Company's common stock will be subject to Rule 144 restrictive legend and will
also contain a restrictive legend reflecting this resale restriction.

        2. The Holder agrees that it will not engage in any short selling of the
Company's common stock during the term of this Agreement.

        3. Beginning January 1, 2006 and ending December 31, 2006, prior to the
Company selling any of its Series A Preferred Stock ("Future Series A
Financing"), the Company will send the terms of any proposed offering by written
notice to the Holders (the "Offer"). Each Holder will have the right to
participate pro rata (as defined below) in the Future Series A Financing by
providing the Company written notice of its acceptance of the Offer within five
(5) days after the Offer is sent (the "Right of First Refusal"). If any Holder

                                      -1-
<PAGE>

accepts the Offer, the Holder must fund the purchase price as described in the
Offer. If any Holder fails to either accept or fund the Offer, as provided for
herein, such Holder shall have waived its rights to participate in that Future
Series A Financing. For the purposes of any Offer under this Section 3, the "pro
rata" of any accepting Holder shall equal the ratio of (i) the aggregate number
of shares of Series A Preferred Stock held of record by such accepting Holder
prior to such Offer divided by (ii) the aggregate number of shares of Series A
Preferred Stock outstanding of record prior to such Offer. The Right of First
Refusal is not transferable or assignable.

         4. Notwithstanding anything contained in this Agreement, a Holder may
transfer his/her/its shares of the Company's Series A Preferred Stock provided
that the transferee executes an agreement to be bound by all of the terms and
conditions of this Agreement and such transfer otherwise complies with
applicable securities laws.

         5. Except as otherwise provided in this Agreement or any other
agreements between the parties, this Agreement shall not effect the Holder's
right to their respective beneficial rights of ownership of the Company's Series
A Preferred Stock or common stock, including the right to vote the Company's
Series A Preferred Stock and common stock for any and all purposes.

         6. The Company's per share price restrictions of the common stock
covered by this Agreement shall be appropriately adjusted should the Company
undergo a forward split or a reverse split or otherwise reclassify its shares of
the Company's common stock.

         7. The conversion restrictions on the Company's Series A Preferred
Stock set forth in this Agreement shall be in addition to all other restrictions
on transfer imposed by applicable United States and state securities laws, rules
and regulations.

         8. The Company or each Holder who fails to fully adhere to the terms
and conditions of this Agreement shall be liable to every other party for any
damages suffered by any party by reason of any such breach of the terms and
conditions hereof. Each Holder agrees that in the event of a breach of any of
the terms and conditions of this Agreement by any such Holder, that in addition
to all other remedies that may be available in law or in equity to the
non-defaulting parties, a preliminary and permanent injunction and an order of a
court requiring such defaulting Holder to cease and desist from violating the
terms and conditions of this Agreement and specifically requiring such Holder to
perform his/her/its obligations hereunder is fair and reasonable by reason of
the inability of the parties to this Agreement to presently determine the type,
extent or amount of damages that the Company or the non-defaulting Holder may
suffer as a result of any breach or continuation thereof. In the event of
default hereunder, the non-defaulting parties shall be entitled to recover
reasonable attorney's fees incurred in the enforcement of this Agreement.

         9. This Agreement sets forth the entire understanding of the parties
hereto with respect to the subject matter hereof, and may not be amended except
by a written instrument executed by the parties hereto.

         10. The Company will be the transfer agent for all Series A Preferred
Stock and any Holder desiring to convert Series A Preferred must submit their
Series A stock certificate along with written instructions as to the number of
Series A shares they wish to convert directly to the Director of Investor

                                      -2-
<PAGE>

Relations, 2911 South Shore Blvd. League City Texas, 77573. The Holder will
receive a new Series A Preferred certificate as well as a common stock
certificate reflecting the transfer directly back from the Company. Holders
should anticipate that the conversion process will require approximately 75 days
from the point the request is received by the Company due to the 65 day
pre-notification requirement of the Series A Preferred designation as well as
the processing time for the new Series A Preferred and common stock
certificates.

         11. This Agreement shall be governed by and construed in accordance
with the laws of the State of Texas applicable to contracts entered into and to
be performed wholly within said State; and the Company and the Holder agree that
any action based upon this Agreement may be brought in the United States and
state courts of Harris County, Texas only, and each submits
himself/herself/itself to the jurisdiction of such courts for all purposes
hereunder.

        IN WITNESS WHEREOF, the undersigned have duly executed and delivered
this Agreement as of the day and year first above written.

Date: December 8, 2005                ERF WIRELESS, INC.
