                                   A. PARTIES

         This agreement is entered into this ____ day of _____________, 2005, by
and between INGEN TECHNOLOGIES, INC., a Georgia corporation and
__________________, a resident or entity of ________________ ("subscriber").


                             B. RECITALS AND SUMMARY

         Ingen Technologies, Inc. ("COMPANY") intends to raise up to $1 million
utilizing Rule 504 of Regulation D of the SEC in states that have adopted (at
least in substantial form) the Model Accredited Investor Exemption ("MAIE"),
plus California - under Corp. Code section 25102(n). Common shares purchased
hereunder will be unrestricted shares. Management has no current plans to pay
commissions or finders fees, but is not prohibited from so doing.

         The COMPANY is a "development stage enterprise" with no significant
operating history and no sales of its products to date. Mr. Scott R. Sand is CEO
and Chairman of the COMPANY and should be contacted by prospective investors
desiring more information concerning this investment opportunity.

         The COMPANY is competing in the electronic medical monitoring device
industry against competitors with superior track records and resources. 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.

         Those persons or entities domiciled in the following states are
eligible to participate in this AGREEMENT: Alaska, Arizona, California,
Colorado, Connecticut, Delaware, District of Columbia, Indiana, Kansas,
Kentucky, Maine, Maryland, Nevada, New Jersey, New Mexico, North Dakota,
Oklahoma, Pennsylvania, Rhode Island, South Dakota, Tennessee, Texas, Utah,
Vermont, Virginia, Washington, West Virginia, Wisconsin.

         The amount of investment in this AGREEMENT is $_______________, for the
purchase of __________________ shares of unrestricted COMPANY common shares (to
be issued by the COMPANY'S Transfer Agent ASAP upon receipt of funds). Payment
must be received within five business days of the date first written above.

                         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.


                                      -1-


         There is no impound amount in this offering. All proceeds from this
stock offer and purchase hereunder will go directly into the COMPANY's bank
account to be utilized as contained below. Prospective investors should realize
that additional investment may be required 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 developmental stage of operation.

                       D. COMPLIANCE WITH SECURITIES LAWS

         The parties understand that this Agreement is in the nature of 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 common stock, 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 OxyAlert and for general and
administrative expenses. Management should be contacted directly for more
specific information regarding OxyAlert and the COMPANY's operation.

                     F. ALLOCATIONS AND PROFIT PARTICIPATION

         The COMPANY has no current dividend policy in place. The COMPANY is a
development stage COMPANY 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. Sand is attached hereto. Other officers and directors

                     I. SALE OF COMPANY STOCK BY MANAGEMENT

         Management will market the unrestricted common stock offered hereby.

no current plans to pay commissions or finders fees to third parties regarding
