EXHIBIT 10.2

Letter of Agreement Between National Scientific Corp. & E4World
Regarding Electronic Component Logistics Services (ECLS)

January 4, 2001

The parties agree on a common language basis as follows;



| | 1. |  | Purpose: To cooperate on the importing and immediate reselling of
up to $10M worth of PC/electronic components from a set of Korean
Manufacturers (Manufacturers, listed below) to a set of U.S.
Distributors (Distributors, listed below) over the next 12 months,
starting January 4, 2001. These transactions will be engineered with
no material inventory carrying risk or obsolesce risk for either party,
because these transactions will be designed so that no Manufacturer
purchase order will be released from NSC before NSC has in-hand
non-cancelable POs with Net 30 terms or better from Distributors,
which E4 shall facilitate and secure for NSC.

|
| | 2. |  | Start-up: E4 will assist NSC in establish the necessary
contractual relationships in the next 30 days with known set of Korean
Manufacturers and a known set of U.S. Distributors in order to support
this business. E4 will assist NSC in establishing the necessary
facilities and contractual relations in L.A. to manage the logistics
for these transactions on a fully outsourced and insurance basis, whose
performance E4 shall oversee and assure during this course of this
agreement.

Net 60) FOB L.A. terms or better from the Manufacturers. NSC shall use
its good faith and credit to secure these terms from the Manufacturers.
All goods will be delivered to pre-determined locations in LA, where
NSC will briefly assume title. The goods will be stored using bonded

|
| | 9.  |  | Indemnification: Because of its unique relationships between E4
and the Manufacturers and Distributors in this transaction, E4 agrees
to indemnify NSC and its officers and directors against the following
items: inventory loss, inventory obsolesce, failure of Manufacturers
to deliver on accepted Purchase Orders, illegal acts or Bankruptcy by
Manufactures or E4, failure of Distributors to make promised payments
in such as fashion that Manufacturer terms are violated.
Indemnification shall be limited to working with all parties using all
best efforts to complete the transactions as originally designed and
documented in the associated Purchase Orders. This shall include but
not be limited to buying at Landed Cost any Inventory held for longer
than 90 days by NSC, should NSC request such a remedy. This clause
does not include clerical error or other error by NSC, for which E4 is
not liable.
|
| | 10. |  | Initial Payment:NSC will pre-pay $100,000 to E4 as advance upon
commissions upon execution of this agreement, which shall be treated as
a secured loan until earned, at 12% per annum interest and secured by
the attached note. E4 shall provide best efforts to help NSC perfect
its security interest in this loan. If E4 has failed to generate at
least $500,000 in non-cancelable POs from Distributors for reasonably
available product by March 31, 2001, then the remainder of this advance
shall be refunded on that date to NSC along with a cash penalty of
$10,000. NSC may also request repayment of this $100,000 at any time
if NSC has reason to believe that this agreement has been breached, and
E4 will remit such funds to NSC within 30 business days. Each party
will be responsible for its own expenses.
