MANAGEMENT SERVICES AGREEMENT

THIS MANAGEMENT SERVICES AGREEMENT (this “Agreement”) is entered into as of
September 24, 2007 (the “Effective Date”) between Vivato Networks, Inc., a
Delaware corporation (the “Contractor”), and Catcher Holdings, Inc., a Delaware
corporation having a place of business at 44084 Riverside Parkway, Suite 320

1. Engagement of Services. Contractor agrees to provide to Company the services
specified on Exhibit A hereto (the “Services”).

2. Compensation; Timing. On the Effective Date, Company shall pay Contractor
$60,000, which shall be payment for the first 30 day period in which Contractor
shall provide the Services. After such 30 day period, the Company shall pay an
additional $60,000 for each subsequent 30 day period in which Contractor shall
provide the Services (the “Monthly Fee”). Company will not reimburse any
expenses of Contractor in connection with Contractor’s provision of the
Services. Upon termination of this Agreement for any reason, Contractor will
refund a pro rata amount of the Monthly Fee. Company shall have the right during
normal business hours to audit the documents, books, records and other
information of Contractor as reasonably necessary to determine compliance with
Section 1.

3. Independent Contractor Relationship. Contractor’s relationship with Company
is that of an independent contractor, and nothing in this Agreement is intended
to, or shall be construed to, create a partnership, agency, joint venture,
employment or similar relationship. Contractor will not be entitled to any of
the benefits that Company may make available to its employees, including, but
not limited to, group health or life insurance, profit-sharing or retirement
benefits. Contractor is not authorized to make any representation, contract or
commitment on behalf of Company unless specifically requested or authorized in
writing to do so by a Company manager. Contractor is solely responsible for, and
will file, on a timely basis, all tax returns and payments required to be filed
with, or made to, any federal, state or local tax authority with respect to the
performance of services and receipt of fees under this Agreement. Contractor is
solely responsible for, and must maintain adequate records of, expenses incurred
in the course of performing services under this Agreement. No part of
Contractor’s compensation will be subject to withholding by Company for the
payment of any social security, federal, state or any other employee payroll
taxes. Company will regularly report amounts paid to Contractor by filing Form
1099-MISC with the Internal Revenue Service as required by law.

4. Disclosure and Assignment of Work Resulting from the Services.

4.1 “Innovations” and “Company Innovations” Definitions. “Innovations” means all
discoveries, designs, developments, improvements, inventions (whether or not
protectable under patent laws), works of authorship, information fixed in any
tangible medium of expression (whether or not protectable under copyright laws),
trade secrets, know-how, ideas (whether or not protectable under trade secret
laws), mask works, trademarks, service marks, trade names and trade dress.
“Company Innovations” means Innovations that Contractor, solely or jointly with
others, conceives, develops or reduces to practice related to the Services

4.2 Disclosure and Assignment of Company Innovations. Contractor agrees to
maintain adequate and current records of all Company Innovations, which records
shall be and remain the property of Company. Contractor agrees to promptly
disclose and describe to Company all Company Innovations. Contractor hereby does
and will assign to Company or Company’s designee all of Contractor’s right,
title and interest in and to any and all Company Innovations and all associated
records. To the extent any of the rights, title and interest in and to Company
Innovations cannot be assigned by Contractor to

--------------------------------------------------------------------------------

Company, Contractor hereby grants to Company an exclusive, royalty-free,
transferable, irrevocable, worldwide license (with rights to sublicense through
multiple tiers of sublicensees) to practice such non-assignable rights, title
and interest. To the extent any of the rights, title and interest in and to the
Company Innovations can neither be assigned nor licensed by Contractor to
Company, Contractor hereby irrevocably waives and agrees never to assert such
non-assignable and non-licensable rights, title and interest against Company or
any of Company’s successors in interest.

4.3 Assistance. Contractor agrees to perform, during and after the term of this
Agreement, all acts that Company deems necessary or desirable to permit and
assist Company, at its expense, in obtaining, perfecting and enforcing the full
benefits, enjoyment, rights and title throughout the world in the Company
Innovations as provided to Company under this Agreement. If Company is unable
for any reason to secure Contractor’s signature to any document required to
file, prosecute, register or memorialize the assignment of any rights under any
Company Innovations as provided under this Agreement, Contractor hereby
irrevocably designates and appoints Company and Company’s duly authorized
officers and agents as Contractor’s agents and attorneys-in-fact to act for and
on Contractor’s behalf and instead of Contractor to take all lawfully permitted
acts to further the filing, prosecution, registration, memorialization of
assignment, issuance and enforcement of rights under such Company Innovations,
all with the same legal force and effect as if executed by Contractor. The
foregoing is deemed a power coupled with an interest and is irrevocable.

4.4 Out-of-Scope Innovations. If Contractor incorporates or permits to be
incorporated any Innovations relating in any way, at the time of conception,
reduction to practice, creation, derivation, development or making of such
Innovation, to Company’s business or actual or demonstrably anticipated research
or development but which were conceived, reduced to practice, created, derived,
developed or made by Contractor (solely or jointly) either unrelated to
Contractor’s work for Company under this Agreement or prior to the Effective
Date (collectively, the “Out-of-Scope Innovations”) into any of the Company
Innovations, then Contractor hereby grants to Company and Company’s designees a
non-exclusive, royalty-free, irrevocable, worldwide, fully paid-up license (with
rights to sublicense through multiple tiers of sublicensees) to practice all
patent, copyright, moral right, mask work, trade secret and other intellectual
property rights relating to such Out-of-Scope Innovations. Notwithstanding the
foregoing, Contractor agrees that Contractor will not incorporate, or permit to
be incorporated, any Innovations conceived, reduced to practice, created,
derived, developed or made by others or any Out-of-Scope Innovations into any
Company Innovations without Company’s prior written consent.

5. Confidentiality.

5.1 Definition of Confidential Information. “Confidential Information” means
(a) any technical and non-technical information related to the Company’s
business and current, future and proposed products and services of Company,
including for example and without limitation, Company Innovations, Company
Property (as defined in Section 6), and Company’s information concerning
research, development, design details and specifications, financial information,
procurement requirements, engineering and manufacturing information, customer
lists, business forecasts, sales information and marketing plans and (b) any
information that may be made known to Contractor and that Company has received
from others that Company is obligated to treat as confidential or proprietary.

5.2 Nondisclosure and Nonuse Obligations. Except as permitted in this Section,
Contractor shall not use, disseminate or in any way disclose the Confidential
Information. Contractor may use the Confidential Information solely to perform
the Services for the benefit of Company. Contractor shall treat all Confidential
Information with the same degree of care as Contractor accords to Contractor’s
own confidential information, but in no case shall Contractor use less than
reasonable care. Contractor shall disclose Confidential Information only to
those of Contractor’s employees who have a need to know such

--------------------------------------------------------------------------------

information. Contractor certifies that each such employee will have agreed,
either as a condition of employment or in order to obtain the Confidential
Information, to be bound by terms and conditions at least as protective as those
terms and conditions applicable to Contractor under this Agreement. Contractor
shall immediately give notice to Company of any unauthorized use or disclosure
of the Confidential Information. Contractor shall assist Company in remedying
any such unauthorized use or disclosure of the Confidential Information.
Contractor agrees not to communicate any information to Company in violation of
the proprietary rights of any third party.

5.3 Exclusions from Nondisclosure and Nonuse Obligations. Contractor’s
obligations under Section 5.2 shall not apply to any Confidential Information
that Contractor can demonstrate by written evidence (a) was in the public domain
at or subsequent to the time such Confidential Information was communicated to
Contractor by Company through no fault of Contractor; (b) was rightfully in
Contractor’s possession free of any obligation of confidence at or subsequent to
the time such Confidential Information was communicated to Contractor by
Company; or (c) was developed by employees of Contractor independently of and
without reference to any Confidential Information communicated to Contractor by
Company. A disclosure of any Confidential Information by Contractor (i) in
response to a valid order by a court or other governmental body or (ii) as
otherwise required by law shall not be considered to be a breach of this
Agreement or a waiver of confidentiality for other purposes; provided, however,
that Contractor shall provide prompt prior written notice thereof to Company to
enable Company to seek a protective order or otherwise prevent such disclosure.

6. Ownership and Return of Confidential Information and Company Property. All
Confidential Information and any materials (including, without limitation,
documents, drawings, papers, diskettes, tapes, models, apparatus, sketches,
designs and lists) furnished to Contractor by Company, whether delivered to
Contractor by Company or made by Contractor in the performance of services under
this Agreement and whether or not they contain or disclose Confidential
Information (collectively, the “Company Property”), are the sole and exclusive
property of Company or Company’s suppliers or customers. Contractor agrees to
keep all Company Property at Contractor’s premises unless otherwise permitted in
writing by Company. Within five (5) days after any request by Company,
Contractor shall destroy or deliver to Company, at Company’s option, (a) all
Company Property and (b) all materials in Contractor’s possession or control
that contain or disclose any Confidential Information. Contractor will provide
Company a written certification of Contractor’s compliance with Contractor’s
obligations under this Section.

7. Observance of Company Rules. At all times while on Company’s premises,
Contractor will observe Company’s rules and regulations with respect to conduct,
health, safety and protection of persons and property.

8. No Conflict of Interest. During the term of this Agreement, Contractor will
not accept work, enter into a contract or accept an obligation inconsistent or
incompatible with Contractor’s obligations, or the scope of services to be
rendered for Company, under this Agreement. Contractor warrants that, to the
best of Contractor’s knowledge, there is no other existing contract or duty on
Contractor’s part that conflicts with or is inconsistent with this Agreement.
Contractor agrees to indemnify Company from any and all loss or liability
incurred by reason of the alleged breach by Contractor of any services agreement
with any third party.

--------------------------------------------------------------------------------

of the Merger Agreement.

benefit of Company’s successors and assigns, and will be binding on Contractor’s
assignees.

11.2 Injunctive Relief. Contractor’s obligations under this Agreement are of a
unique character that gives them particular value; Contractor’s breach of any of
such obligations will result in irreparable and continuing damage to Company for
which money damages are insufficient, and Company shall be entitled to
injunctive relief and/or a decree for specific performance, and such other

the laws of the United States of America and by the laws of the State of

performed entirely within Virginia between Virginia residents. Each of the
parties irrevocably consents to the exclusive personal jurisdiction of the
federal and state courts located in Virginia, as applicable, for any matter
arising out of or relating to this Agreement, except that in actions seeking to
enforce any order or any judgment of such federal or state courts located in
Virginia, such personal jurisdiction shall be nonexclusive.

remaining provisions of this Agreement shall not be affected thereby.

--------------------------------------------------------------------------------

11.6 Waiver; Modification. If Company waives any term, provision or Contractor’s
breach of this Agreement, such waiver shall not be effective unless it is in
writing and signed by Company. No waiver by a party of a breach of this
Agreement shall constitute a waiver of any other or subsequent breach by
Contractor. This Agreement may be modified only by mutual written agreement of
authorized representatives of each of the parties.

11.7 Entire Agreement. This Agreement constitutes the entire agreement between
the parties relating to this subject matter and supersedes all prior or
contemporaneous agreements concerning such subject matter, written or oral.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the Effective
Date.
