                           INVESTMENT CONTRACT (DEBT)
                           --------------------------
                   ACCREDITED INVESTORS ONLY (SALVATORE AMATO)

                                   A. PARTIES

         This agreement is entered into this 31st day of May, 2006, by and
between INGEN TECHNOLOGIES, INC., a Georgia corporation and Salvatore Amato, an
accredited investor of New Jersey ("subscriber" or "undersigned").

                             B. RECITALS AND SUMMARY

         Ingen Technologies, Inc. ("COMPANY") intends to raise up to $5 million
or more utilizing Regulation S-B of the SEC ("S-B offering"). The purpose of
this Agreement is for subscriber to supply $ 75,000 in interim financing to the
COMPANY.

         Subscriber will be issued a convertible debenture (see Exhibit "A"
hereto) for 3,750,000 shares of COMPANY restricted common shares at a price of
$0.02 per share. These shares will be registered by the COMPANY in the S-B
offering. The COMPANY states that it will file the S-B registration statement
with the SEC and applicable states (Blue Sky registration) as soon as is
practical.

         The purchase price is payable on or before June 7, 2006. Upon receipt
of payment, COMPANY will deliver the convertible debenture.

         The COMPANY's common stock trades on the Pink Sheets under the symbol
"IGTG." The COMPANY is delinquent in its periodic reporting to the SEC under the
Securities Exchange Act of 1934. The COMPANY did not report from 1998 until it
resumed reporting in November of 2005. The COMPANY is in the process of tracking
down and gathering information for the unreported time periods. COMPANY counsel
is in regular contact with the SEC Enforcement Staff, supplying information
regarding back filing plans. The COMPANY has also pledged to stay current with
new reporting filings as they become due.

         This is a HIGH RISK INVESTMENT that should be undertaken only by
accredited, sophisticated people with the means to risk loss of the entire
investment.

                         C. OTHER TERMS OF THE CONTRACT

         This offering is limited to qualified persons and entities who are
accredited as defined by federal law (Regulation D of the Securities and
Exchange Commission). Subscribers must have the experience, knowledge and
sophistication to ascertain the suitability of this investment opportunity in
relation to their own needs and/or have a pre-existing personal, family or
business relationship with management and/or its officials.

         There is no impound amount in this offering. All proceeds from this
stock debenture Agreement will go directly into the COMPANY's bank account to be
utilized as contained below. Prospective investors should realize that
additional investment is needed before the COMPANY is able to begin the
manufacture and sale of its proprietary products. There is no guarantee the
COMPANY will be able to raise enough funds in this or some other offering
enabling it to progress beyond its current stage of operation.

<PAGE>

                       D. COMPLIANCE WITH SECURITIES LAWS

         The parties understand that this Agreement is a "security" as defined
under applicable state and federal law. This is primarily because the investment
provided for herein is in the nature of a "passive investment" wherein
subscriber is providing funds for the COMPANY through purchase of a convertible
debenture, but not participating in the active management of the funds.

         It is understood that this Agreement will not be registered with any
state or federal securities regulatory authority and that the parties are
relying upon exemptions from registration under state and federal law, or, the
parties are relying on a federal law "private placement" exemption that
pre-empts state law. No state or federal securities regulator has read or passed
upon the merits or adequacy of this Agreement.

                          E. ESTIMATED USE OF PROCEEDS

          Funds will be utilized for engineering, tooling, marketing and
inventory production of the COMPANY's product OxyView and for general and
administrative expenses. Management should be contacted directly for more
specific information regarding OxyView and the COMPANY's operation. In addition,
the COMPANY's EDGAR filings contain information regarding its operation.

                     F. ALLOCATIONS AND PROFIT PARTICIPATION

         The COMPANY has no current dividend policy in place. The COMPANY is a
"going concern" and there are no plans to pay shareholder dividends until and if
the COMPANY progresses to the point of generating sales revenues beyond that
needed to operate and grow the COMPANY.

                                  G. MANAGEMENT

         The resume of Mr. Scott R. Sand, CEO and Chairman, is contained within
