                             SECURED PROMISSORY NOTE


$139,000                                                 Lake Forest, California
March 21, 2002

         For value received, the undersigned Michael A. Armani, an individual
(herein, together with his successors and assigns, collectively called "Maker"),
promises to pay to the order of Telenetics Corporation, a California corporation
(herein, together with its successors and assigns who become holders of this
Note, called "Holder") at its offices set forth on the signature page hereof, or
such other place as Holder may designate in writing, the principal sum of One
Hundred Thirty-Nine Thousand Dollars ($139,000) together with interest on the
unpaid principal amount from time to time owing hereunder, commencing on the
above date, at the rate of 6.75% per annum, simple interest. Interest and
principal payments on this Note shall be payable as follows:

         Two (2) years following the date of this Note, Maker shall pay Holder
the entire outstanding principal amount and all accrued and unpaid interest
thereon.

         This Note is secured by a stock pledge agreement ("Stock Pledge
Agreement") of even date herewith by and between Maker and Holder, covering
certain specified shares of common stock of Telenetics Corporation issued in the
name of Maker.

         Maker acknowledges that late payment to the Holder of the principal and
interest due under this Note will cause the Holder to incur costs not
contemplated herein. Such costs are anticipated to include, without limitation,
reasonable processing and accounting charges. The parties hereto agree that it
would be impractical or extremely difficult to fix the actual damages resulting
from such late payment. Therefore, in the event that principal and interest is
not paid within ten (10) days after the same becomes due under this Note, Maker
agrees to pay Holder an amount equal to five percent (5%) of such overdue
principal and interest payment as a late charge. The parties hereto agree that
this late charge represents a reasonable sum considering all the circumstances
existing as of the date of this Note and represents a fair and reasonable
estimate of the costs that Holder hereof will incur by reason of said late
payment. Acceptance of any late charge by the Holder hereof shall not constitute
a waiver or settlement with respect to any rights which the Holder may have with
respect to the default related thereto, and shall not prevent the Holder from
exercising any other rights and remedies otherwise available to Holder.

         All payments required hereunder shall be calculated on the basis of a
360-day year, divided into twelve 30-day months.

         This Note may be prepaid in whole or in part at any time without
penalty or bonus.

         Both principal and interest shall be paid by Maker in lawful money of
the United States of America in the form of a cashier's or certified check or
wire transfer of immediately available federal funds to Holder's account. The
rights and remedies of Holder provided in this Note shall be cumulative and
concurrent, and may be pursued singularly, successively or together. This Note

<PAGE>

has been executed under and shall be construed and enforced in accordance with
the laws of the State of California from time to time in effect, except to the
extent that the United States federal laws preempt or otherwise control the laws
of the State of California, including without limitation, the extent to which
the United States federal law permits Holder to contract for, charge or receive
a greater amount of interest than do the laws of the State of California.

         Time is of the essence of this Note. Upon an Event of Default (as
defined below) under this Note, the entire unpaid principal and all accrued
interest, at the option of Holder, shall at once become due and payable.

         The following events shall be considered Events of Default with respect
to this Note:

                  (1) An Event of Default shall have occurred under the Stock
                  Pledge Agreement;

                  (2) Maker shall default in the payment of any part of the
                  principal or accrued and unpaid interest on this Note for more
                  than ten (10) days after it shall become due and payable,
                  whether at maturity or at a date fixed for prepayment or by
                  acceleration or otherwise;

                  (3) Maker shall make an assignment for the benefit of
                  creditors, or shall file a voluntary petition for bankruptcy,
                  or shall seek or consent to or acquiesce in the appointment of
                  any trustee, receiver or liquidator of Maker's assets, or of
                  any substantial part of the assets of Maker; or

                  (4) Within thirty (30) days after the commencement of any
                  proceeding against the Maker seeking liquidation of Maker's
                  assets or similar relief under any present or future statute,
                  law or regulation, such proceeding shall not have been
                  dismissed or, within thirty (30) days after the appointment
                  without the consent or acquiescence of Maker of any trustee,
                  receiver or liquidator of Maker's assets or of any substantial
                  part of the assets of Maker, such appointment shall not have
                  been vacated.

         Whenever used herein, the words "Maker" and "Holder" shall be deemed to
include their respective heirs, personal representatives, successors and
assigns.

         This Note shall be assignable by Holder only in connection with a sale
of all or substantially all of the assets or capital stock of Telenetics
Corporation, which shall include a merger after which the holders of the capital
stock of Telenetics Corporation own less than a majority of the outstanding
capital stock of the surviving corporation in that merger; provided, that Holder
shall provide Maker with twenty (20) days' advance written notice of its
intention so to assign this Note, which notice shall identify the proposed
assignee.

         Maker hereby agrees, subject only to any limitation imposed by
applicable law, to pay all expenses, including reasonable attorneys' fees and
legal expenses, incurred by Holder ("Costs") in endeavoring to collect any
amounts payable hereunder which are not paid when due, whether by declaration or
otherwise. Maker agrees that any delay on the part of Holder in exercising any


                                      -2-

rights hereunder will not operate as a waiver of such rights. Holder shall not
by any act, delay, omission or otherwise be deemed to have waived any of its
rights or remedies, and neither this Note nor any term hereof may be waived,
amended, discharged, modified, changed, or terminated orally, nor shall any
waiver of any provision hereof be effective except by an instrument in writing
signed by Maker and Holder.

receipt by the addressee or, if mailed, upon the expiration of forty-eight (48)
hours after deposit in the United States Postal Service, certified mail, postage
prepaid, addressed to the address of Maker or Holder as hereinafter set forth:
