              Re:      Note Extension
Dear                :

         We are writing in regard to the note payable to you by Telenetics
Corporation ("Telenetics"). As you are aware, Telenetics has not been able to
repay the note payable to you at the original due date. We had, as of May 31,
2001, offered two options in an attempt to resolve this matter to our mutual
benefit. You have not yet responded to accept either of those options prior to
the expiration of the offer on June 15th. We have however been advised that you
have an interest in resolving this matter on terms that are a variation of our
original offer. Accordingly, by this letter, Telenetics desires to offer you the
opportunity to take advantage of either of the following in lieu of repayment of
the Note under its current terms:

                  a.       The maturity date of the Note would be extended to
                           January 2, 2003;

                  b.       The interest rate of the Note would be increased by
                           two percentage points per annum;

                  c.       You would receive a three-year warrant to purchase
                           one share of common stock for each $5.00 of the
                           current principal amount of the Note. The warrant
                           would have an initial exercise price of $1.00 per
                           share, would be subject to adjustment for stock
                           splits, recapitalizations, mergers and consolidations
                           and would carry piggyback registration rights,
                           subject to certain restrictions;

                  d.       The Note would be convertible into common stock of
                           Telenetics at the rate of $0.70 per share until March
                           31, 2002. The conversion right would be subject to
                           adjustment for stock splits, recapitalizations,
                           mergers and consolidations and would carry piggyback
                           registration rights, subject to certain restrictions;

                  e.       The Note would be callable if the shares of the
                           Telenetics common stock are traded at or above $1.40
                           for ten consecutive; and

                  f.       The Note would be fully transferable.
