                                   Demand Note
                                   -----------

Date: June 19, 2002

For Value Received, the undersigned agrees to pay to the order of FASTNET
Corporation, at 3864 Courtney St. Suite 130 Bethlehem, PA 18107, the principal
sum of AMOUNT, plus accrued interest, on the date ninety (90) days after FASTNET
Corporation delivers written notice of demand for payment to the undersigned (at
the undersigned's address set forth below or such other address for the
undersigned then appearing on the books and records of FASTNET Corporation),
provided such notice of demand will not be delivered to the undersigned prior to
November 1, 2003. Interest will accrue from the date hereof on the unpaid
principal balance at a rate of 3.75% per annum, simple interest, which shall be
payable upon pro-rate repayment of the principal. Notwithstanding the foregoing,
by written notice delivered to FASTNET Corporation, the undersigned may elect to
repay any or all of the principal and accrued interest, by direct payment or by
payroll withholding in equal monthly installments of principal and interest over
a period not to exceed sixty (60) months. There shall be no penalty for
prepayment. If installment prepayment is elected, interest at the above rate
will continue to accrue on the unpaid balance over the repayment period.

Failure to make any payment within three business days after receipt of written
notice from FASTNET Corporation that such payment is overdue, or institution of
any bankruptcy or insolvency proceedings by or against the undersigned, will be
an event of default, entitling FASTNET Corporation to immediately accelerate and
collect all unpaid amounts under this Note and to pursue all additional remedies
available at law or in equity. Upon any such event of default, the undersigned
agrees to pay all reasonable legal fees and collection costs incurred by FASTNET
Corporation in collecting this Note, and the interest rate on this Note will be
increased to 5.75% from the date due until the date paid.

Should any part but not the whole of this Note for any reason be declared
invalid or unenforceable, such decision shall not affect the validity or
enforceability of any remaining portion, which remaining portion shall remain in
force and effect as if this Note had been executed with the invalid or
unenforceable portion eliminated. This Note shall be governed by the laws of the
State of Pennsylvania and the parties consent to the exclusive jurisdiction of
the federal and state courts located in Pennsylvania.

This Demand Note is issued in replacement of a Promissory Note dated August 9,
2001, which prior Promissory Note is hereby cancelled.

IN WITNESS WHEREOF and intending to be legally bound the undersigned has
executed this Note.

Corlund Electronics ______________________ REPAYMENT AGREEMENT
It is hereby Stipulated by and between Corlund Electronics, Tustin (hereinafter
"Creditor") and Telenetics Corporation (hereinafter "Debtor"), that Debtor is
indebted to Creditor for the payment of a term loan to Debtor in the principal
sum of One Million, Two Hundred Thousand Dollars ($1,200,000.00) together with
interest thereon at the rate of nine percent (9%) per annum from August 30,
2002. As a result, Debtor promises to pay to Creditor the above referenced sum
in one (1) installment of Sixty Thousand Dollars ($60,000.00) on November 30,
2002 and the remaining balance of principle and interest in twelve (12) equal
monthly installments commencing February 28, 2003 and continuing on the last day
of each calendar month and all due and payable on or before January 31, 2004.

         All installments hereunder shall be applied first to the payment of all
interest accrued to the date of such payments, and the balance, if any, shall be
applied to the payment of principal.

         The occurrence of any of the following shall be deemed to be an event
of defaults ("Event of Default") hereunder:

         (a)      Failure to pay any installment of principal and/or interest
                  when due pursuant to terms hereof;
         (b)      Institution of proceedings to be adjudicated a bankrupt or
                  having insolvency proceedings against it; filing a petition,
                  answer of consent seeking reorganization or relief under the
                  federal bankruptcy laws or any other applicable federal or
                  state law (whether now in effect or enacted in the future);
                  consenting to the filing of any such petition or to the
                  appointment of a receiver, liquidator, assignee, trustee, or
                  other similar official for any business owned by the
                  Undersigned or of substantially all of its assets; making a
                  general assignment benefit of creditors or admitting in
                  writing its liability to pay its debts generally as they come
                  due.

         Upon the occurrence of and Event of Default hereunder, which Debtor
         fails to cure within fifteen (15) days, Creditor shall have the
         option to declare the entire unpaid principal balance hereof,
         together with all accrued interest thereon to be immediately due and
         payable, to demand payment thereof and to exercise all rights and
         remedies then available to Creditor hereunder or under any other
         document or instrument securing this Note or under applicable law. No
         delay or omission on the part of the Creditor in exercising any right
         under this Note or under any of the agreements referred to in this
         Note shall operate as a waiver of such right.
                   Creditor and Debtor shall stipulate and agree that none of
         the terms and provisions contained in this Note or in any other
         document or payment of interest at a rate in excess of the maximum
         interest rate permitted to be charged by the laws of the State of
         California. In the event Creditor shall collect monies which are
         deemed to constitute interest which would otherwise increase the
         effective interest rate on this Note to a rate in excess of that
         permitted to be charged by the laws of the State of California, all
         such sums deemed to constitute interest in excess of the maximum rate
         shall, at the option of Creditor be credited to the payment of
         principal or returned to the Undersigned.

                   The unpaid principal balance of this Note outstanding from
         time to time, together with all accrued but unpaid interest thereon,
         may be prepaid at any time at the option of the Undersigned, in whole
         or in part, without permission or penalty. The Undersigned hereby
         waives diligence, presentment, protest, dishonor and nonpayment of
         this Note, and expressly agree that, without in any way affecting the
         liability of the Undersigned hereunder, Creditor may extend the
         maturity date or the time for payment of any installment due
         hereunder, accept additional security, release any party liable
         hereunder and release any party liable hereunder and release any
         security now or hereafter securing this Note. The Undersigned further
         waives, to the full extent permitted by law, the right to plead any

                   If balance due under this agreement is not paid when due or
         if any Event of Default occurs, the Undersigned promises to pay all
         costs of enforcement and collection, including but not limited to
         reasonable attorney's fees whether or not such enforcement and
         collection includes the filing of a lawsuit.
                   Every provision of this agreement is intended to be
         severable. In the event any term or provision hereof is declared to
         be illegal or invalid for any reason whatsoever by a Court of
         competent jurisdiction, the remaining terms and provisions shall
         remain binding and enforceable.
                   This Note shall be governed and construed in accordance
         with the laws of the State of California and shall be deemed to have
         been entered into in Irvine, California.
