     will reflect all Advances, charges and payments made on the Line of
     Credit.

     be executed solely through Authorized Agents.  These are the only
     persons authorized to execute transactions for Borrower under this
     Agreement and Borrower shall cause these Authorized Agents to provide a
     specimen of their signatures.  Borrower shall revoke the authority of
     its Authorized Agents or appoint other Authorized Agents only upon

interest due for the preceding month on total outstanding Advances
from the Line of Credit.  Interest will be due in arrears and the
interest due must be paid to Bank on the due date shown on each billing
statement.  If payment is not received within ten (10) Business Days after the
due date shown on the billing statement, Borrower authorizes Bank to charge
the Line of Credit for the amount of the interest due for the preceding month
so long as such charge does not cause the outstanding principal balance to
exceed the Line of Credit Limit or the Borrowing Base, whichever is less. 
Bank, in failing to render an interest statement, does not waive its right to
receive or collect interest payments.

including outside attorneys' fees, to amend the Loan Agreement or any of the
Loan Documents.  A reasonable fee may also be charged for Bank's review of any
request by the Borrower to modify or waive any restrictive covenants.  A fee
charged to modify or waive a restrictive covenant does not imply that Bank
consented to the modification or waiver, but is only to reimburse Bank for its
time and effort in reviewing the request by Borrower.  Bank shall issue a
statement for these fees.  If the fees are not paid by the 15th day of the
following month, Borrower directs Bank to add the amount to the principal
balance of the Loan.  Failing to render a statement does not waive the right
to receive or collect these fees.

     This Strategic Alliance (herein referred to as the "AGREEMENT") is made
and entered into as of 18 September 1996 between SkyHook Technologies, Inc.
(herein referred to as "STI"), a Utah corporation, and Tracor Aerospace, Inc.
(herein referred to as "TRACOR'), a Texas corporation, who are the PARTIES
(each being a PARTY) to this AGREEMENT.  The companies desire to enter into a
long-term business relationship wherein TRACOR will manufacture STI's multi-
hook Cargo Management System (CMS) for delivery to domestic and foreign
customers.  In consideration of the mutual promises contained herein, the
parties agree as follows:

I . STRATEGIC TEAM RESPONSIBILITIES.

    (a)  STI has completed the design of the PRODUCT (as defined in
Paragraph 2 below) in its present, form and will continue to be responsible
for the engineering development of the PRODUCT to meet customer needs and to
respond to competitive considerations.  The engineering function will include
hardware and software development and configuration management.  STI will be
responsible for marketing the PRODUCT to foreign and domestic customers.

    (b)  TRACOR will be the manufacturer and installer of the PRODUCT and
will make its expertise in this area available to STI to optimize such
activities.  TRACOR may provide sales and marketing assistance to STI for
domestic and foreign sales.  Such assistance may include development of
strategic marketing plans, identification of potential customers, distribution
of sales literature, introduction of STI sales personnel to potential
customers and recommending other strategic sales and marketing activities.

     2.   PRODUCT DEFINED.
     
     The PRODUCT to be manufactured by TRACOR for STI is STI's proprietary,
patented Cargo Management System (CMS).  It is a multi-hook helicopter cargo 
transport device consisting of hardware, software and electronics.  The PRODUCT
is currently offered in three and six hook configurations.  TRACOR shall be
provided with updated engineering drawings, specifications and any other
pertinent information prior to commencing the manufacture of the PRODUCT.  STI
represents and warrants that such engineering drawings, specifications and
other pertinent information are sufficiently complete and accurate so as to
enable a reasonably skilled manufacturer of the type of equipment delineated
therein to manufacture the PRODUCT in accordance with the specifications
applicable thereto.  In the event any discrepancies or shortcomings in such
documents come to light STI will promptly take appropriate action to
<PAGE>
correct or supplement such documents; TRACOR will assist in such corrective
actions as required.  STI will maintain configuration control and shall be
responsible for configuration management of the PRODUCT.

3.   PROCUREMENT PROCEDURE.
      
     The PARTIES will develop a format for a purchase order to be issued by STI 
to TRACOR  for each batch of PRODUCT to be manufactured and/or installed.  Each
purchase order will provide all of the information required to manufacture 
and/or install the PRODUCT.

4.   PRICING.
    
     Initial prices will be those quoted by TRACOR in its "SkyHook CMS Pricing"
quote dated 8/2/96 at 3:36 PM (see Exhibit A), plus or minus any adjustments 
made for final design changes, test requirements and scope changes, as 
required.  Price adjustments will be made following the same pricing 
methodology used by TRACOR to price the original quote shown in Attachment A. 
The price for other PRODUCT configurations will be calculated by TRACOR 
following the same pricing methodology used by TRACOR to price the three-hook 
unit.  Once the prices have been adjusted as defined above and agreed to by 
the PARTIES, those prices shall remain in effect for a period of eighteen (I8) 
months.  Prices shall be renegotiated by the PARTIES from time to time 
thereafter in good faith, consistent with the original pricing methodology.

5.   LEAD TIME.
    
     TRACOR will make the first shipment of PRODUCT 90 days after receipt of 
order, but will use its best efforts to reduce this delivery time.  The 
PARTIES will mutually agree on the delivery rate for subsequent deliveries on 
each purchase order placed by STI.

6.   PAYMENT TERMS.
    
    During the first 18 month period of this AGREEMENT, STI will pay TRACOR the
net amount due ninety days ("Net 90") from the date TRACOR ships PRODUCT.  
Payment terms on subsequent deliveries will be determined by mutual agreement 
of the PARTIES, consistent with business conditions and customer payment terms.

7.   FOB POINT AND SHIPPING.
    
     The FOB point is TRACOR's plant.  On the day TRACOR ships PRODUCT, it win 
fax to STI the shipping information, including cost, and STI will bill 
the customer for shipping costs.  TRACOR will drop-ship PRODUCT to any non-
restricted country, per Purchase Order instructions.  STI will abide by any 
export restrictions placed upon it by any United States government entity with 
export jurisdiction.


                                        2
<PAGE>
8.   EXPORT/IMPORT.
     
     TRACOR will assist STI with all domestic and foreign export/import
requirements, with details to be worked out between the PARTIES as soon as 
possible.  As seller of the PRODUCT, STI will retain primary responsibility 
for export/import requirements.

9.   WARRANTY.
     
    As the manufacturer of the PRODUCT, TRACOR provides a one-year warranty 
on materials and workmanship.  The standard warranty is attached hereto as
Exhibit B.

10.  ADDITIONAL INSURED.
     
     TRACOR shall name STI as additional insured under its product liability
insurance with respect to that portion of the PRODUCT manufactured by TRACOR,
with liability limits per occurrence of $ 10 million.

11.  QTP AND ATP.
     
     TRACOR shall fabricate and test the PRODUCT in accordance with test 
procedures to be jointly developed and approved by STI and TRACOR.  The 
PARTIES anticipate that one standard QTP (to be defined by the PARTIES) 
will apply to all or most PRODUCT manufactured, and a standard ATP 
(to be defined by the PARTIES) will apply to each customer's order.  However, 
the PARTIES recognize that unique tests may be required by some customers, and 
that customer-specific ATP's will be developed in such circumstances.

12.  CONFIDENTIALITY.
     
     On 2 August 1996, the PARTIES hereto signed an "Agreement for Non-
Disclosure of Proprietary Information (Mutual Exchange)" which is made a part 
of this AGREEMENT by reference.  Terms of this Non-Disclosure Agreement shall 
remain in effect for two years after the termination of this AGREEMENT.

13.  ASSIGNMENT.
     
     The PARTIES shall not assign, contract, grant a license or otherwise

                                  Warranty
                                  --------

TRACOR warrants that each PRODUCT manufactured by TRACOR will be new and
unused and will be delivered free from defects in material and workmanship and
will satisfy the requirements specified in the PRODUCT specifications.  This
warranty will be effective for one year from the date of receipt by STI or
STI's customer, whichever occurs earlier.  If a defect appears in the PRODUCT
within one year from the date of delivery by TRACOR and STI notifies TRACOR
within such one year period plus 15 days and returns the defective equipment
or part thereof with transportation charges prepaid, TRACOR shall thereupon
correct any defect, including nonconformance with the specifications, at its
option, either by repairing or replacing any defective part or parts, and
shall deliver the repaired or replaced part to STI with transportation charges
prepaid.

The foregoing warranty shall not apply to any PRODUCT that has been subject to
misuse, neglect, accident, improper application, or exposure to an environment
beyond the limits described in the specification, nor to any product that has
been altered or repaired outside of TRACOR's factory without TRACOR's written
consent, nor to any product component that is consumed in ordinary use such
as, but not limited to, lamps, knobs, and gaskets.  Nor shall the warranty
extend to anyone other than STI and STI's immediate customer.

THE FOREGOING WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING WITHOUT LIMITATION, ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR
A PARTICULAR PURPOSE AND ANY WARRANTY AGAINST INFRINGEMENT, AND ALL SUCH OTHER
WARRANTIES ARE HEREBY DISCLAIMED AND EXCLUDED BY TRACOR.

All failures caused by and attributed to normal wear and tear or improper
maintenance, use or repairs by STI or third parties are not defects and are
excluded from the warranty.

In no event shall TRACOR be liable for consequential damages of any nature.
