other jurisdiction, or participate in the financing, operation,
management or control of, any firm, partnership, corporation,
entity or business that engages or participates in a "competing
business purpose."  The term "competing business purpose" shall
mean the design, development, marketing and sale of advanced cable
broadband solutions, including but not limited to, voice-over IP
technologies and circuit switched technologies.

   (b) During the Non-Compete Period, Employee shall not, directly or
indirectly, without the prior written consent of the Company or
Parent, solicit, encourage or take any other action which is
intended to induce or encourage, or has the effect of inducing or
encouraging, any employee or customer of the Parent, Company, or
any subsidiary of Company to terminate his or her employment with
or customer relationship with Parent, the Company, or any
subsidiary of the Company.

   (c) The Geographic Area shall mean anywhere in the world where the
Parent, Company or any subsidiary of the Company conducts business
including, without limitation, the United States and Israel.

   (d) "Good Cause" shall mean (i) a criminal conviction in respect
of a Felony (Pesha), (ii) material refusal to comply with
reasonable rules, regulations, policies directions and restrictions

repeated abuse (following at least one written warning from the
Company) of alcohol or any use of narcotics or other controlled
substances, (iv) conduct which the Company reasonably determines to
constitute insubordination, (v) conduct (A) involving dishonesty
against the Company or breach of fiduciary duty, or (B) materially

construed as a series of separate covenants, one for each county,
city, state, or any similar subdivision in any Geographic Area.
Except for geographic coverage, each such separate covenant shall
be deemed identical in terms to the covenant contained in the
preceding paragraphs.  If, in any judicial proceeding, a court
refuses to enforce any of such separate covenants (or any part
thereof), then such unenforceable covenant (or such part) shall be
eliminated from this Agreement to the extent necessary to permit
the remaining separate covenants (or portions thereof) to be
enforced.  In the event that the provisions of this Section are
deemed to exceed the time, geographic or scope limitations
permitted by applicable law, then such provisions shall be reformed
to the maximum time, geographic or scope limitations, as the case
may be, permitted by applicable laws.

   (f) Employee acknowledges that the nature of the Parent's and
Company's business is such that if Employee were to become employed
by, or substantially involved in, the business of a competitor of
the Parent or the Company soon following the termination of
Employee's employment with the Company, it might be difficult for
the Employee not to rely on or use the Parent's and Company's trade
secrets and confidential information.  The Employee has agreed to
enter into this Agreement to reduce the likelihood of disclosure of
the Parent's and the Company's trade secrets and confidential
information.

   (g) Employee also acknowledges that the limitations of time,
geography, and scope of activity agreed to in this Agreement are
reasonable because, among other things, (i) the Parent and Company
are engaged in a highly competitive industry, (ii) the Employee has
had unique access to, and acknowledges that he will continue to
have access to, the trade secrets and know how of the Parent and
Company, including without limitation the plans and strategy (and
in particular the competitive strategy) of the Parent and Company,
(iii) the Employee is receiving significant compensation in
connection with the Share Purchase and pursuant to this Agreement,
and (iv) the Employee believes that in the event the Employee's
employment with the Company ended, Employee would be able to obtain
suitable and satisfactory employment without violation of this
Agreement.

   (h) Employee agrees that it would be impossible or inadequate to
measure and calculate the Parent's or Company's damages from any
breach of the covenants set forth in this Section.  Accordingly,
Employee agrees that if he breaches any provision of this Section,
the Parent or Company will have available, in addition to any other
right or remedy otherwise available, the right to obtain an
injunction from a court of competent jurisdiction restraining such
breach or threatened breach and to specific performance of any such
provision of this Agreement.  Employee further agrees that no bond
or other security shall be required in obtaining such equitable
relief, nor will proof of actual damages be required for such
equitable relief.  Employee hereby expressly consents to the
issuance of such injunction and to the ordering of such specific
performance.

9. Assignment.  This Agreement will be binding upon and inure to
the benefit of (a) the heirs, executors and legal representatives
of Employee upon Employee's death and (b) any successor of the
Company.  Any such successor of the Company will be deemed
substituted for the Company under the terms of this Agreement for
purposes of enforcing the Company's rights hereunder.  The
provisions of this Agreement will thereafter apply only to the
business of the Company and Parent and not the business of such
successor.  For this purpose, "successor" means any person, firm,
corporation or other business entity which at any time, whether by
purchase, merger or otherwise, directly or indirectly acquires all
or substantially all of the assets or business of the Company.
None of the rights of Employee to receive any form of compensation
payable pursuant to this Agreement may be assigned or transferred
except by will or the laws of descent and distribution.  Any other
attempted assignment, transfer, conveyance or other disposition of
Employee's right to compensation or other benefits will be null and
void.

communications called for hereunder shall be in writing and shall
be deemed given (i) on the date of delivery if delivered
