-- Hubs will be configured in Motorola's desired polarization configuration, the
   polarization will be identified when Motorola "issues releases" to Millitech.
-- When "releases are issued" to Millitech new line items will be added to this
   Purchase Order and the quantities will be reduced on line item 1 and 2.
-- Warranty is [***] from the date of shipment from Millitech for all items
   shipped against this Purchase Order.
-- Motorola will provide Millitech with a delivery forecast (forecast will be
   for [***] Hubs and [***] CPE's spread out by month until 12-31-01) with the
   release of this Purchase Order and it will be updated on a monthly basis.
-- Motorola will finalize hand delivery requirements 16 weeks prior to delivery.
   This firm release will identify the quantities and delivery dates as well as
   the part numbers and/or technical requirements for the hardware. Once a
   month, Motorola will "issue revised releases" to reflect the new forecast
   (hard deliveries).

NOTE 2: -- Millitech will execute advance procurement and planning to meet our
           delivery forecast. With this, Millitech may commit to procure up to
           20 weeks of material (per our schedule). In the event that Motorola's
           sales do not develop as planned for the LMDS Program, Motorola will
           be liable to Millitech for material procured by Millitech within the
           20-week window. If hardware has not been assembled, Motorola's
           maximum liability will not exceed [***] per CPE and [***] per Hub.
           Motorola will be 100% responsible for all hard commits within the 16-
           week delivery window and has the option to change the quantities in
           weeks 12-16 by 33% with no charge.
        -- In the event that Motorola's LMDS sales do not develop as planned,
           Motorola will be liable to Millitech for 20-weeks of production as
           stated above only. The unit prices as shown on this P.O. will remain
           the same (Hubs [***] each and [***] each for the CPE's) in the event
           that sales are not as high as projected.
        -- Program reviews will be held monthly between Millitech and Motorola,
           we will rotate facilities.
        -- Millitech has the rights to convert the (Release 2 CPE's) to the
           (Release 3 CPE's) any time after written acceptance by Motorola.

1.  DEFINITIONS.  As used throughout this contract, including, if any,
provisions incorporated by reference the following terms shall have the meaning
set forth below:

(a)  The term "Seller" means the person, firm or corporation executing this
     contract with Motorola and who will furnish the work or services provided
     for herein.

(b)  The term "Motorola" unless otherwise defined shall mean the Space and
     Systems Technology Group of Motorola, Inc.

(c)  The term "prime contract" means the contract with the customer.

(d)  The word "contract" unless otherwise modified shall mean the agreement.

(e)  Except as otherwise provided in this contract, the term "subcontract"
     includes purchase orders placed by the Seller under this contract and all
     references to "supplies" shall include "services", if the contract wholly
     or in party provides for the furnishing of services.

2.  ORDER OF PRECEDENCE.  The rights and obligations of the parties to this
contract shall be subject to and governed by the Statement of Work, these Terms
and Conditions, and any proposals, specifications or other documents or
provisions which are made a part of this contract by reference or otherwise. To
the extent of any inconsistency between (i) the Statement of Work and these
Terms and Conditions and (ii) proposals, specifications or other documents or
provisions which are made a part of this contract by reference or otherwise, the
Statement of Work and these Terms and Conditions shall control. To the extent of
any inconsistency between (i) the Statement of Work and (ii) these Terms and
Conditions, the Statement of Work shall control.



3.   CHANGES.

(a)  Motorola may at any time, without notice to the sureties of any, through
     written directions, require reduction or addition or work, issue additional
     restrictions, or extend the performance of the work all within the general
     scope of this contract.

(b)  If any such direction causes an increase or decrease in the cost of, or the
     time required or the performance of, this contract, or otherwise affects
     any other provision of this contract, whether changes or not changed by any
     such direction, an equitable adjustment shall be made (1) in the contract
     price or time of performance or both, and (2) in such other provisions of
     the contract as may be so affected, and the contract shall be modified in
     writing accordingly.

(c)  Any claim by the Seller for adjustment under this article must be asserted
     in writing within 30 days from the date of receipt by the Seller of the
     notification of change provided, however, that Motorola, if it decides that
     the facts justify such action, may receive and act upon any such claim
     asserted at any time prior to final payment

<PAGE>

     under this contract. Nothing in this article shall excuse the Seller from
     proceeding with the contract as changed. Failure to agree to any adjustment
     shall be a dispute concerning a question of fact within the meaning of the
     article of this contract entitled "Disputes".

(d)  Where the full cost, or substantially the full cost, of property made
     obsolete or excess as a result of a change is included in the Seller's
     claim for adjustment, Motorola shall have the right to prescribe the manner
     of disposition of such property.

(e)  Motorola engineering and technical personnel may from time to time render
     assistance or give technical advice to, or discuss or effect and exchange
     of information with the Seller's personnel concerning the work hereunder.
     Such actions shall not be deemed to be a change under this article and
     shall not vest Seller with authority to change the work hereunder.  In the
     event Seller receives an instruction, order or advice that he deems to be a
     change from anyone other than Motorola's Supply Management Department, he
     shall immediately advise Motorola's Purchasing Department of that
     instruction, order or advice, Seller shall not be entitled to any
     adjustment of the contract price, delivery schedule or other contract
     provisions because of actions taken by the Seller pursuant to said
     instruction, order or advice unless and until and only to the extent such
     instruction, order or advice shall be included in a Purchase Order Revision
     or Change Order or Supplemental Agreement to this contract issued by
     Motorola's Supply Management Department, in writing, whenever any change
     received from any representative of Motorola affects specifications,
     quantities, delivery, prices or other conditions of this contract.

(f)  The Seller shall not make any changes in the work or end items (including
     assemblies, subassemblies, parts and components thereof) which do not
     conform to the requirements of this contract without the prior written
     consent of Motorola.  Motorola may present as a procedure for the reporting
     and approval of changes initiated by the Seller.

4.  NOTICES.  All notices required or permitted to be sent by either party
hereto shall be deemed sufficiently given if sent by prepaid certified mail to
the address shown on the first page of this contract for each party and to the
attention of the individual who executes this contract on behalf of the party to
whom the notice is sent.  All notices shall be deemed given when they are sent
by certified mail and deposited in the mail addressed in the aforesaid manner.
Either party may designate, in writing, a different manner of address for
notices under this contract.

5.  INSURANCE AND INDEMNIFICATION.  In the event the Seller, its employees,
agent, subcontractors, or lower-tier subcontractors enter premises occupied by
or under the control of Motorola in the performance of this contract, the Seller
agrees that it will be responsible to Motorola for, and indemnify and hold
harmless Motorola, its officers and employees, from any loss, cost, damage,
expense or liability by reason of property damage or personal injury of
whatsoever kind or character arising out of, as a result of, or in connection
with such performance occasioned by the negligence or other fault, act or
<PAGE>

omission, of the Seller, its employees, agents, subcontractors, or lower-tier
subcontractors and the Seller agrees that it and its subcontractors will
maintain public liability and property damage insurance in reasonable limits
covering the obligations set forth above and will maintain Worker's Compensation
Insurance covering all employees performing this contract on premises occupied
or under the control of Motorola provided, however, that the Seller may maintain
a self-insurance program in lieu of Worker's Compensation Insurance if
authorized and qualified to do so pursuant to statutory authority.  Seller shall
provide certificates of such insurance upon request.

6.  INSPECTION.

(a)  All services and supplies (which term throughout this article includes the
     Seller without limitation raw material, components, intermediate assemblies
     and end products) may be subject to inspection and test by Motorola, to the
     extent practicable at all reasonable times and places including the period
     of manufacture and, in any event, prior to final acceptance.

(b)  In case any supplies or lots of supplies are defective in material or
     workmanship or otherwise not in conformity with the requirements of this
     contract, Motorola shall have the right either to reject them (with or
     without instructions as to their disposition) or to require their
     correction.  Supplies or lots of supplies which have been rejected or
     required to be corrected shall be removed or, if permitted or required by
     Motorola, corrected in place by and at the expense of the Seller promptly
     after notice, and shall not thereafter be tendered for acceptance unless
     the former rejection or requirement for correction is disclosed.  If the
     Seller fails to promptly remove such supplies or lots of supplies which are
     required to be removed or promptly to replace or correct such supplies or
     lots of supplies, Motorola (i) may, by contract or otherwise, replace or
     correct such supplies and charge to the Seller the cost occasioned to
     Motorola, or (ii) may terminate this contract for default as provide din
     the article of this contract entitled "Default".  Unless the Seller
     corrects or replaces such supplies within the delivery schedule, Motorola
     may require the delivery of such supplies at a reduction in price which is
     equitable under the circumstances.  Failure to agree to such reduction in
     price shall be a dispute concerning a question of fact within the meaning
     of the article of this contract entitled "Disputes."

(c)  If any inspection or test is made by Motorola on the premises of the Seller
     without additional charge shall provide all reasonable facilities and
     assistance for the safety and convenience of inspectors in the performance
     of their duties.  If the Motorola inspection or test is made at a point
     other than the premises of the Seller, it shall be at the expense of
     Motorola except as otherwise provided in this contract, provided that, in
     case of rejection, Motorola shall not be liable for any reduction in value
     of samples used in such inspection or test.  All inspections and tests
     shall be performed in such a manner as not to unduly delay the work.
     Motorola reserves the right to charge to the Seller any additional cost of
     inspection or test when supplies are not ready at the time such inspection
     or test is requested by the Seller or when reinspection or retest is
     necessitated
<PAGE>

     by a prior rejection. Acceptance or rejection of the supplies shall be made
     as promptly as practicable after delivery except as otherwise provided in
     this contract, but failure to inspect and accept or reject supplies shall
     neither relieve the Seller from responsibility for such supplies as are not
     in accordance with the contract requirements nor impose liability to
     Motorola therefore.

(d)  The inspection and test by Motorola of any supplies or lots thereof does
     not relieve the Seller from any responsibility regarding defects or other
     failures to meet the contract requirements which may be discovered prior to
     acceptance.  Unless otherwise provided in this contract, acceptance shall
     be conclusive except with respect to latent defects, fraud, such gross
     mistakes amounting to fraud, and the Seller's warranty obligations.

(e)  The Seller shall provide and maintain a quality and inspection system
     acceptable to Motorola covering the supplies hereunder.  Records of all
     inspection work by the Seller shall be kept complete and available to
     Motorola during the performance of this contract and for such longer
     periods as may be specified in this contract.

(f)  Seller hereby certifies that all supplies in the quantities so called for
     on the face of this contract will conform with all requirements, drawings,
     and related documents referenced by or in this contract. The required test
     and inspection reports resulting from compliance with this contract will be
     maintained on file and be made available for review by Motorola's
     representative, at any reasonable time.

7.  TITLE AND RISK OF LOSS.

(a)  Unless this contract specifically provides for earlier passage of title,
     title to supplies covered by this contract shall pass to Motorola upon
     final acceptance by Motorola or the Government, regardless of when Motorola
     takes physical possession.

(b)  Unless this contract specifically provides otherwise, the transportation of
     supplies to be delivered by Seller to Motorola shall be F.O.B. destination
     and all risk of loss of or damage to the supplies covered by this contract
     shall remain with the Seller until final acceptance by Motorola or receipt
     of the supplies by Motorola at the destination specified in this contract,
     whichever is later.

(c)  If the contract specifies the transportation of supplies to be delivered by
     Seller to Motorola as F.O.B. origin (i.e. Seller's facility), all risk or
     loss of or damage to the supplies covered by this contract shall remain
     with the Seller until Seller delivers the supplies to an authorized carrier
     for shipment to Motorola.

(d)  Notwithstanding (b) and (c) above, risk of loss of or damage to supplies
     which fail to conform to the requirements of this contract as to give a
     right or rejection shall remain with Seller until cure by Seller or final
     acceptance by Motorola, whichever is later, at which time (b) or (c) above
     shall apply.
<PAGE>

8.  PAYMENTS.

(a)  Payment of the contract price or any portion thereof for supplies delivered
     or services rendered shall not constitute acceptance.  The Seller shall be
     paid, upon admission of property certified invoices or vouchers, the prices
     stipulated herein for supplies delivered or services rendered less
     deductions, if any, as herein provided.

(b)  If more than one article of this contract authorizes the temporary
     withholding of amounts otherwise payable to the Seller for supplies
     delivered or services performed, the total of the amounts so withheld at
     any one time shall not exceed the greatest amount which may be withheld
     under any one such article at that time, provided that this limitation
     shall not apply to (i) withholdings pursuant to any article relating to
     wages or hours of employees; (ii) withholdings not specifically provided
     for by this contract, and (iii) the recovery of overpayments.

(c)  It is understood that the efficient use by Motorola of the supplies called
     for hereunder require that the data called for by this contract be
     delivered not later than the time or respective times herein specified.  If
     such data is not delivered at said time or times, Motorola may at its
     election, so long as such data remains undelivered, unless the delay in
     delivery thereof arises out of causes beyond the control and without the
     fault or negligence of the Seller within the meaning of the article hereof
     entitled "Default," withhold payment to the Seller for any of the amounts

15.  DEFAULT.

(a)  Motorola may, subject to the previsions of paragraph (c) below, by written
     Notice of Default to the Seller terminate the whole or any part of this

     negligence of either of them, the Seller shall not be liable for any
<PAGE>

     materials") as the Seller has specifically produced or specifically
     acquired for the performance of any part of this contract which has been
     terminated.  Seller shall protect and preserve property in possession of
     the Seller in which Motorola has an interest.  Payment for completed
     supplies delivered to and accepted by Motorola shall be at the contract
     price.  Payment for manufacturing materials delivered to and accepted by
     Motorola and for its protection and preservation of property shall be an
     amount agreed upon by the parties.  Failure to agree shall be a dispute
     concerning a question of fact within the meaning of the article of this
     contract entitled "Disputes."

(e)  If, after notice of termination of this contract under the provisions of
     paragraph (a) of this article, it is determined that the failure to perform
     is due to causes beyond the control and without the fault or negligence of
     the Seller or subcontractor pursuant to the provisions of paragraph(c) of
     this article, such Notice of Default shall be deemed to have been issued
     pursuant to the articles of this contract entitled "Termination" and the
     rights and obligations of the parties hereto shall in such an event be

     terminated for reasons other than default, reasonable costs resulting from
     the Stop Work Order shall be allowed in arriving at the termination
     settlement.

     terminated for default, the reasonable costs resulting from the Stop Work
     Order shall be allowed by equitable adjustment or otherwise.
