other hand,  do hereby release and discharge each other from all actions, causes
of action, suits, claims, demands, liabilities, rights, remedies, debts, dues,
sums of money, accounts, reckonings, bonds, bills, specialties, covenants,
contracts, controversies, agreements, promises, variances, trespasses, damages,
judgments, extents, executions, claims, and demands whatsoever, in law,
admiralty, or equity that the releasor or the releasor’s successors and assigns

reason of any matter, cause, or thing whatsoever from the beginning of the world
to the date of the execution of this Amendment, including, without limitation,
and claim that was or could have been brought in the Lawsuits.  This release
does not apply to obligations undertaken in this Amendment.

meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended,
shall not acquire or hold NMRX stock for five years from the date of execution
of this Amendment.

8.  
The Parties agree that the execution of this Amendment shall not be construed as
an admission of liability, fault, or wrongdoing by any Party with regard to the
claims asserted in the Lawsuits.  The Parties further agree that no Party shall
offer this Amendment, or any conduct or statements made in the negotiation
thereof, in any proceeding as evidence of liability.

9.  
The Parties represent to each other that the persons executing this Amendment on
their behalf, and those executing the Joint Instructions for submission to the
Escrow Agent and the Stipulation of Dismissal, have full authority to bind that
Party to the terms of this Amendment.

10.  
This Amendment may be executed in any number of counterparts, including those
transmitted to and among the Parties to this Amendment via facsimile or
electronic mail, with the same effect as if the signatures on each counterpart
were upon a single instrument.  All counterparts, taken together, shall
constitute the Amendment.

11.  
No change or waiver of any provision of this Amendment shall be valid unless the
same is in writing and signed by all Parties to this Amendment.  The invalidity,
illegality, or unenforceability of any provision or any part of any provision of
this Amendment shall not affect or impair the validity, legality, or
enforceability of any other provision or part of any provision of the Amendment
except as stated herein.  The Amendment supersedes all negotiations related to
the Amendment, whether oral or written, and statements made before or after its
acceptance.  This Amendment is the entire agreement among the Parties concerning
the subject matter hereof.  Each Party warrants that it has carefully read the
Amendment, knows and understands the contents and meaning hereof, that the terms
hereof are contractual and not a mere recital, and signs the same after
consultation with legal counsel and with the intent to be legally bound thereby.

12.  
The Parties each hereby warrant that none of them has assigned any rights or
claims in the Lawsuits to any third party.  The Parties each further agree that
none shall assign this Amendment or any of its rights or obligations under it
without the prior written consent of the other Parties, which consent may not be
unreasonably withheld.  Nothing herein shall preclude any Party to the Amendment
from assigning it to its parent, an affiliate, a subsidiary, or to an entity
that assumes any obligations of a Party under the Amendment by operation of law,
by providing written notice to the other Parties.

13.  
The Parties shall not make, repeat, or publish to any third party any false,
disparaging, defamatory, accusatory, or derogatory remarks or references about
one another, whether oral or in writing, relating to the subject matter of the
Lawsuits.  NMRX’s and Buyer’s obligations under this Paragraph are limited to
only those individuals who are Executive Officers (as defined in Rule 16a-1(f)
of the Securities Exchange Act of 1934, as amended) of NMRX who are acting in
their capacity as Executive Officers at the time they make a remark or reference
that allegedly violates this Paragraph.

14.  
Other than the covenants, releases, and agreements expressly set forth herein,
no Party shall have any continuing obligations to any other party under the APA
or its schedules or its exhibits, including, without limitation, the Severance
and Non-Competition Agreements between NMRX and David Ronsen, Scott Rosenzweig
and Gary Naden, the Intellectual Property and Confidentiality Agreements between
NMRX and David Ronsen, Scott Rosenzweig and Gary Naden, the Registration Rights
Agreement between NMRX and Seller, and the Guaranty executed by David Ronsen,
Scott Rosenzweig and Gary Naden in favor of NMRX; provided, however, that
nothing herein shall in any way impair the property interests of Buyer evidenced
by the APA and the Bill of Sale.

IN WITNESS WHEREOF, Numerex Corp., Orbit One Communications, LLC, Orbit One
Communications, Inc., Lava Lake Technologies, LLC, David Ronsen, Scott
Rosenzweig, and Gary Naden have caused this Amendment to the APA to be executed
