1.02     Termination of a Material Definitive Agreement

         Ingen Technologies, Inc. ("Company") has reviewed the sales progress of
Invacare Supply Group, Inc. ("ISG") between August 1, 2007 and March 15, 2008;
and as such it has been determined that due to the oxygen providers
reimbursements cuts, equipment ownership transfers to patients and competitive
bidding with home oxygen therapy, that it would be in the best interest of the
Company to sell direct to the patients through hospital respiratory therapy,
pulmonology facilities and COPD (coronary pulmonary disease) support
organizations. The Company has requested ISG to terminate its Oxyview(TM)
distribution contract and ISG complied by letter dated March 25, 2008. This
agreement was entered into in August of 2007 and reported by the registrant in a
Form 8-K filed on August 22, 2007. The termination letter invokes Section 1(b)
of the contract, setting a final termination date of June 30, 2008 (unless moved
forward by mutual consent). The letter also states that ISG will not be
purchasing any further "Ingen Oxyview product."

         Re:  Ninety (90) Day Notice of Termination August 2007 Medical Supply
              Master Distributor Agreement

Dear Scott,

As a follow up to our recent conversations, Invacare Supply Group, Inc. ("ISG")
hereby terminates the August 2007 Medical Supply Master Distributor Agreement
(including all amendments and exhibits) between ISG and Ingen Technologies, Inc.
("Ingen").

We are terminating under our rights in Section 1(b) by giving the required
ninety (90) day notice of termination: the last day of the Agreement will be
June 30, 2008 unless we mutually agree with you in writing to move up that date
of termination.

Before that date, we will be in contact with you to settle any outstanding
invoices (if any) and other miscellaneous matters. Please also note that ISG
will not be making any further purchases of the Ingen Oxyview product and so
there is no need for you to stock any product on our behalf.

If you have any questions, please contact me.

Sincerely,


/s/ Doug Harper
