$[______]
                                                              Irvine, California
                                                              September 30, 2004

         FOR VALUE RECEIVED, the undersigned, Telenetics Corporation, a
California corporation (the "COMPANY"), hereby promises to pay to
[________________] (together with its successors, representatives and assigns,
the "HOLDER") the principal sum of [_____________] Dollars and [______] Cents
($_______) together with simple interest as provided below on the unpaid
principal amount hereof at the rate of three and one-half percent (3.5%) per
annum. This is one of the "Notes" (the "UNSECURED NOTES") issued pursuant to the
letter agreement regarding the proposed offering of unsecured promissory notes,
common stock and warrants executed by the Company and the investors signatory
thereto (the "INVESTORS") dated September 30, 2004.

         1. PAYMENTS OF PRINCIPAL AND INTEREST. Interest on the unpaid principal
portion of this Note will accrue at a rate of three and one-half percent (3.5%)
per annum from the date hereof. Payments of principal and interest shall be
payable in cash as follows:

                  (a) Principal shall be paid by the Company to the Holder on
March 31, 2006 (the "MATURITY DATE"); and

                  (b) Interest payments hereunder shall be paid in equal
quarterly installments, in arrears, by the Company to the Holder on March 31,
June 30, September 30 and December 31 of each year so long as any balance of
principal and interest of this Note remains outstanding. The first interest
payment shall be due on December 31, 2004 (which payment shall represent all
accrued interest from September 30, 2004 through December 31, 2004); and

                  (c) Any remaining outstanding balance of principal and
interest of this Note shall be due and payable on the Maturity Date or at such
earlier time as provided herein. The undersigned may prepay all or part of the
outstanding principal balance of this Note, together with all accrued but unpaid
interest thereon, only in accordance with this Note. All payments of principal
of and interest on this Note shall be in such coin or currency of the United
States of America as at the time of payment shall be legal tender for payment of
public and private debts.

         If the Company defaults in the payment of any part of the principal of
or interest on this Note for more than three (3) days after the same shall
become due and payable ("PAYMENT DEFAULT"), then, to the extent permitted by
law, the Company will pay interest to the Holder, payable on demand, on the
outstanding principal balance of the Note from the date of the Payment Default
until such Payment Default is cured, at the rate of the lesser of twelve percent
(12%) per annum and the maximum applicable legal rate per annum, and the Company
will pay the Holder a penalty equal to two percent (2%) of the principal balance
outstanding at the date of the Payment Default.

         2. DEFAULT.

                  2.1 EVENTS OF DEFAULT. If any of the following events (herein
called "EVENTS OF DEFAULT") shall occur:

                  (a) a Payment Default occurs and is not cured within thirty
(30) days after the Payment Default occurs;

                  (b) the Company breaches or defaults (other than a Payment
Default) in the performance of any covenant or warranty of the Company in this
Note, and continuance of such breach for a period of ten (10) days after there
has been given, by registered or certified mail, to the Company by the Holder, a
written notice specifying such breach or default and requiring it to be
remedied;

                  (c) a court having jurisdiction in the premises shall enter a
decree or order for relief in respect of the Company in an involuntary case
under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, or appointing a receiver, liquidator, assignee, custodian,
trustee, sequestrator (or similar official) of the Company or for any
substantial part of its property, or ordering the winding-up or liquidation of
its affairs, and such decree or order shall remain unstayed and in effect for a
period of sixty (60) consecutive days; or

                  (d) the Company shall commence a voluntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, shall consent to the entry of an order for relief in an involuntary case
under any such law, or shall consent to the appointment of or taking possession
by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other
similar official) of the Company or for any substantial part of its property, or
shall make any general assignment for the benefit of creditors, or shall fail
generally to pay its debts as they become due, or shall take any corporate
action in furtherance of any of the foregoing;

then and in any such event the Holder may at any time (unless all defaults
theretofore or thereupon shall have been remedied) at its option, by written
notice to the Company, declare this Note to be due and payable, whereupon the
same shall forthwith mature and become due and payable without presentment,
demand, protest or other notice, all of which are hereby waived.

                  2.2 REMEDIES ON AND NOTICES OF DEFAULT. In case any one or
more Events of Default shall occur, the Holder may proceed to protect and
enforce the rights of Holder by a suit in equity, action at law or other
appropriate proceeding, whether for the specific performance of any agreement
contained in this Note, or for an injunction against a violation of any of the
terms or provisions hereof or thereof, or in aid of the exercise of any power
granted hereby or thereby or by law. No course of dealing and no delay on the
part of the Holder in exercising any right shall operate as a waiver thereof or
otherwise prejudice the Holder's rights. No remedy conferred by this Note upon
the Holder shall be exclusive of any other remedy referred to herein or now or
hereafter available at law, in equity, by statute or otherwise.

HOWEVER, that the Company shall not be required to preserve any right or

rate, extend the Maturity Date or modify any provision of this Section 5 without
the consent of the Holder of this Note.

with the laws of the State of California. Any dispute, action, litigation or
other proceeding concerning this Note shall be brought and maintained in the
state or federal courts having jurisdiction over the matter and located in
Orange County, California. If any one or more of the provisions contained in

be invalid, illegal or unenforceable in any respect, the parties agree that such

and enforceable. In any event, such provision shall be separable and shall not
limit or affect the validity, legality or enforceability of any other provision
hereunder.

                  (b) If this Note is collected by law or through an attorney
