Nayna Executes Definitive Agreement for the Acquisition of Abundance Networks


Santa Clara, Calif., - December 6, 2005 - Nayna Networks, Inc., (OTCBB: NAYN), a
provider of next generation network solutions headquartered in Santa Clara,
today announced it has entered into a definitive agreement to acquire
privately-held Abundance Networks headquartered in Shelton, Connecticut, with
regional sales and R&D offices in Mumbai, India. Founded in 2002, Abundance is a
recognized supplier of TDM/Ethernet over SONET/SDH optical Access solutions in
India. This acquisition is the latest step in Nayna's expansion into high-growth
markets such as India.

Pursuant to the terms of the definitive agreement, subject to various standard
closing conditions and approvals Nayna will acquire substantially all of the
assets of Abundance Networks, including its wholly owned subsidiary in India, in
an all-stock transaction that is anticipated to close within 30 days. At
closing, Nayna will issue Abundance Networks 900,000 shares of restricted Nayna
stock plus an additional number of shares of restricted Nayna stock equal to (i)
$1,000,000 divided by (ii) the average of the closing prices of its common stock
during the twenty consecutive trading days ending one day prior to the closing
date. The 900,000 shares of restricted Nayna stock to be issued at closing will
be subject to price protection at a value of $2.00 per share with any adjustment
to be made on the first anniversary of closing. In addition, 350,000 of the
shares to be issued at closing will be held in escrow for fifteen months to
satisfy any indemnification claims by Nayna. Abundance can earn up to an
additional 1,750,000 shares based on the achievement of certain revenue and
earnings based milestones through March 31, 2007. Any shares released from
escrow to Abundance or issued to Abundance upon achievement of any earn out
milestones will also be subject to price protection at a value of $2.00 per
share with any adjustments to be made at the time of delivery of the shares to
Abundance.

Abundance's popular AN series of multiplexers can be used in a wide range of
stand-alone, Point-of-Presence (POP), Add/Drop (ADM) and transmission
applications. The extensive feature set of the AN series enhances uptime and
optimizes bandwidth usage. AN multiplexers boast hot-swappable cards and
non-blocking bandwidth assignments that optimize bandwidth usage and reduce
maintenance costs. Abundance's products meet or exceed the latest general
requirements established by the Government of India and are approved for use in
the India Telecom Network. Standards compliance includes: Telcordia, ANSI, ITU,
FCC, EN, UL and NEBS.

"We are excited about the speedy pace of this acquisition and addition of the
synergies from both the companies," said Naveen Bisht, president and CEO, Nayna
Networks. "Early customer interest has been high and the feedback has been very
positive."
