EXHIBIT 10.2

                         Line of Credit Promissory Note
                                February 15, 2004

Pursuant to this Line of Credit Promissory Note (the "Note"), John R. Coghlan,
as lender, agrees to provide up to $2,500,000 in the fomr of a line of credit to
Temporary Financial Services, Inc., a Washington corporation ("TFS") as
borrower. This Line of Credit Promissory Note expires on December 31, 2004.
Advances against the line may be requested from time-to-time by TFS so long as
the aggregate outstanding advances against the line of credit do not exceed
$2,500,000, unless the line of credit limitation is waived by Mr. Coghaln. Mr.
Coghlan agrees to deliver the funds requested by TFS by suitable means such as
wire transfer, check or cashiers check. The line will expire and all outstanding
advances will be due and payable, with accrued interest, on December 31, 2004.

Interest on each outstanding advance will be calculated from the date of the
advance to the date of repayment at the rate of 8% per annum on the basis of
actual days elapsed and a year of 365 days. In the event payments are made prior
to maturity, the payments will be applied first to accrued interest then due on
all outstanding advances, and then to reduce the oldest advance first. Payments
toward accrued interest and any outstanding advance may be made at any time
without penalty. After maturity, if the outstanding advances are not repaid, the
outstanding balances, including accrued interest to the date of maturity, will
bear interest at the lower of a per annum rate of 18% or the maximum rate
authorized by the applicable law.

Mr. Coghlan and TFS acknowledge that the primary purpose of this line of credit
is to enable TFS to provide a $2,000,000 line of credit to Genesis Financial,
Inc., and an operating line of credit to Everyday Staffing. TFS agrees to pay
over to Mr. Coghlan, any origination fees and other loan fees received by TFS
from Genesis. The TFS/Genesis line of credit agreement is attached and
incorporated into this agreement by reference. This Note is unsecured and does
not create any priority or security interest in specific TFS loan receivables or
other assets.

No failure by Mr. Coghlan to exercise, and no delay in exercising any right or
remedy under this Note shall operate as a waiver against Mr. Coghlan, nor shall
any single or partial exercise by Mr. Coghlan of any right or remedy under this
Note preclude any other or further exercise of any right or remedy. The rights
and remedies of Mr. Coghlan are cumulative and not exclusive of any other rights
or remedies which Mr. Coghlan may otherwise have.

In any dispute with respect to this Agreement, the prevailing party shall be
entitled to reasonable attorney's fees and other costs and expenses incurred in
litigating or otherwise resolving or settling the dispute. This Note shall be
governed by and construed in accordance with the laws of the State of
Washington.

                   WAREHOUSING LINE OF CREDIT PROMISSORY NOTE
            Dated February 20, 2002 as amended February 15, 2003 and
                                  April 1, 2003

      On February 20, 2002, Temporary Financial Services, Inc. ("TFS") and
Genesis Financial, Inc. ("GENESIS") entered into a Warehousing Line of Credit
Promissory Note and related loan documents (collectively the "Line of Credit")
for a $2,000,000 secured line of credit. TFS was the lender and GENESIS was the
borrower under these documents. The Line was intended to provide GENESIS with
funds for the purchase of seller financed real estate contracts. The Warehousing
Line of Credit Promissory Note and applicable extensions is due March 31, 2004.
On February 15, 2004, TFS and GENESIS entered into an agreement to extend the
line of credit through December 31, 2004 in order to allow GENESIS additional
time to locate a new lender or negotiate new terms for the Line of Credit with
TFS.

      TFS and Genesis have agreed to new terms on the Line of Credit, as
follows:

1.    The due date of the Warehousing Line of Credit Promissory Note is extended
      to December 31, 2004.

2.    The interest rate (8%) and the Line of Credit limit ($2,000,000) set forth
      in the Warehousing Line of Credit Promissory Note, with extensions, are
      maintained for the extension period.

3.    In addition to the interest rate charged for the extension period, GENESIS
      will also pay a Commitment Fee for the Warehousing Line of Credit
      Promissory Note extension in the amount of $20,000 payable in cash. This
      additional Commitment Fee relates to the extension period.

      This February 15, 2004 Addendum supercedes and replaces the Addendum dated
April 1, 2003. Except as noted in Paragraphs 1 through 3, above, all other terms
of the Line of Credit remain in full force and effect, including the terms and
conditions described in "Advance and Repayment Procedures," the "Financial
Covenants and Reporting Obligations," the "Security Agreement," and the
"Guaranty."

      Dated this 15th day of February, 2004.

Dear Dr. Maglich:

Subject:  Proposal for Preliminary Manufacturing Facility Assessment Consulting
          Services Within the Framework of the DFW Homeland Security
          Alliance's Initiative Lockwood Greene Proposal No. DA-04-0052

Lockwood Greene is pleased to have this opportunity to provide assistance to
HiEnergy during this crucial period of development for your business. We propose
to provide a preliminary study and develop an understanding for the elements of
a facility to build your detection devices and meet your anticipated capacity
requirements.

BACKGROUND

HiEnergy Technologies, Inc. has developed Stoichiometer technology capable of
non-evasively detecting chemical formulas of explosives and other illicit
substances. This technology has allowed HiEnergy Technologies to create a family
of products for several markets and applications including: airport and customs
screening; biological weapons, landmine and bomb squad explosive detection; and
industrial quality control processing. HiEnergy Technologies has built and
successfully tested products around this technology and need to quickly define
the manufacturing, resources that will be needed to commercially produce these
products. Based on our initial assessments and understanding of the potential
market, we would propose evaluation of a manufacturing facility with a capacity
to produce up to 1,000 units per year.

Lockwood Greene proposes, as a first step in this process, to conduct a
preliminary manufacturing-needs assessment with HiEnergy Technologies around
this current family of products.

SCOPE OF WORK

Lockwood Greene will provide the following services under this proposal:

1.       Meet with HiEnergy Technologies' personnel for up to a two-day period
         in Irvine, California for the purpose of obtaining information on the
         physical make-up of the current HiEnergy Technologies family of
         products.

2.       Conduct analysis of manufacturing needs based on product information.

3.       Determine site requirements - size, containment, and other special
         needs identified by HiEnergy.

4.       Provide a report with preliminary layout and estimates of facility
         needs for commercial production of these products.

DELIVERABLE AND OUTPUT RESULTS

From the information obtained during the joint HiEnergy/Lockwood Greene meeting,
Lockwood Greene will conduct studies and assemble a report of estimated facility
and other resource needs required to manufacture HiEnergy's family of products
for commercial production. It is anticipated that the following topics will be
addressed in the report:

1.       Physical manufacturing facility with functional block area sizing and
         layout depicting fabrication, sub-assembly, and final assembly
         requirements.

2.       Warehousing requirements and layout

3.       Shielding requirements

4.       Security requirements

5.       Office and support area estimates and layout

6.       Quality and testing area requirements and layout

7.       Preliminary make/buy recommendations based on manufacturing needs

8.       Rough-order-of-magnitude capital cost requirement

9.       Estimated production headcount

10.      Estimated milestone facility design and construction schedule

11.      List of concept assumptions

It is understood that the information presented in this report will be a very
high-level view of the facility requirements for the manufacture of these
products and is intended to provide HiEnergy Technologies' management an
estimate only of these needs. The information within this report will provide a
good platform to enter the more detailed concept design activity of a
Visioneering Session.
