MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS


NOTE:  To the extent any statements in this Form 10-Q may be deemed to be
forward-looking, such statements should be evaluated in the context of the
risks and uncertainties inherent in the Company's business, including the
Company's continuing dependence on certain major customers, the anticipated
seasonality of its business, the timing of or rescheduling of customer orders
and other risks and uncertainties set forth in the Company's Annual Report on
Form 10-K for the fiscal year ended April 30, 1996.

Sales to the Company's largest customer are seasonal and may cause the
Company's quarterly revenues and earnings to fluctuate significantly.

RESULTS OF OPERATIONS:

Net sales increased from $20,118,444 for the three month period ended January
31, 1996 to $21,910,286 for the three month period ended January 31, 1997.  For
the first nine months of fiscal 1997 net sales increased to $70,086,628 from
$48,225,397 for the comparable period of the prior year.  The increase in net
sales was due primarily to sales to Nighthawk Systems, Inc. (NSI), which
contributed $23,726,822 in net sales for the nine months ended January 31, 1997
and $11,763,300 for the comparable period in the prior year.  The Company began
manufacturing for NSI in August 1995, and NSI's market is an emerging market
which could lead to volatility in the forecast.  The Company anticipates NSI
will account for a significant percentage of the Company's net sales in fiscal
1997.  Sales to NSI are seasonal due to the nature of the product and generally
are greater in the Company's second and third quarter.

Gross profit decreased during the three month period ended January 31, 1997 to
$2,859,221 from $2,927,383 for the same period of the prior fiscal year.  For
the nine months ended January 31, 1997 gross profit increased to $10,225,410 as
compared to $7,196,498 for the same period in 1996.  The increase in absolute
dollars is due to a higher sales volume.  Gross profit decreased as a percent
of net sales for the nine months ended January 31, 1997 to 14.6% from 14.9% for
the same period in the prior year, which is primarily due to product mix.

Selling and administrative expenses decreased for the three month period ended
1/31/96 from $1,360,591 to $1,185,831 for the three months ended January 31,
1997.  Selling and administrative expenses as a percentage of net sales for the
nine months ended January 31, 1997 were 6.5% or $4,546,409 compared to 6.6% or
$3,192,486 in the same period in the prior year.  The increase in absolute
dollars for the nine months ended January 31, 1997 was primarily due to an
increase in commission expense related to the higher sales volume.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

- - cont'd

Interest expense for bank debt and capital lease obligations for the
three month period ended January 31, 1997 was $483,980 compared to $487,358 for
the same period in the prior year.  For the nine months ended January 31, 1997
interest expense increased to $1,399,110 from $1,169,979 in the same period for
the prior fiscal year.  This increase is primarily attributable to a higher
outstanding balance on the line of credit and interest expense associated with
increased capital lease obligations.

As a result of the foregoing, income before taxes increased from
$1,182,297 in the three month period ended January 31, 1996 to $1,261,730 for
the same period in fiscal year 1997.  Net income increased from $709,378 for
the three month period ended January 31, 1996 to $757,038 for the three month
period ended January 31, 1997.  Earnings per share were $ .26 and $ .25 for the
three months ended January 31, 1996 and 1997, respectively. For the nine months
ended January 31, 1997 primary earnings per share were $ .93 compared to $ .64
for the same period in the prior year.

LIQUIDITY AND CAPITAL RESOURCES:

The Company's primary source of liquidity has been cash provided by net income
and borrowings from its secured lender.  The Company had working capital of
$21,247,057 at January 31, 1997 and $20,622,238 at January 31, 1996.  This
represents a current ratio of 2.75 and 3.34 for these periods, respectively.

For the nine month period ended January 31, 1997, the primary use of cash from
operations was an increase in inventories.  The net cash used for investing
activities for the same period was $2,126,696, which was primarily attributable
to machinery and equipment purchases.

To the extent that the Company provides the funds necessary to operate its
Mexican operations, the amount of funds available for use in the Company's
domestic operations may be depleted.  The funds, which ordinarily derive from
the Company's cash from operations and borrowings under its revolving credit
facility, equal approximately $1,649,500 for the three month period ended
January 31, 1997 and $4,387,500 for the nine month period ended January 31,
1997.

Net cash provided by financing activities totaled $1,136,570 for the nine
months ended January 31, 1997 compared to $5,744,378 in the prior year.  Net
proceeds under the line of credit decreased from $6,701,898 for the nine months
ended January 31, 1996 to $1,545,336 for the nine months ended January 31,
1997.

                         TERMS AND CONDITIONS OF LEASE

1. LEASE.  LESSOR hereby leases to LESSEE and LESSEE hereby hires and takes
from LESSOR, the personal property set forth on the EQUIPMENT Schedule above
and any Schedule attached hereto with all accessories incorporated therein
and/or affixed thereto, hereinafter referred to as EQUIPMENT.
2. RENTALS.  During and for the original term hereof LESSEE hereby agrees to
pay LESSOR as and for rental of the EQUIPMENT the amounts specified above as
monthly or other calendar period rental multiplied by the number of months or
periods specified above.  The first rental payment shall be made on the
effective date as set forth above.  In the event the effective date is omitted
when the LEASE is executed by the LESSEE, the LESSOR is authorized to and shall
insert the effective date of this LEASE which shall be the date of delivery of
EQUIPMENT.  Subsequent monthly or other period rental payments shall be due on
the same day of subsequent months or other calendar periods as the effective
date of this LEASE.  All payments shall be made at the office of the LESSOR at
1113 S. Milwaukee Avenue, Libertyville, IL  60048, or as otherwise directed by
the LESSOR or assignee in writing.
3. TERM.  The original term of this LEASE shall commence on the date that the
EQUIPMENT is delivered to LESSEE and shall terminate upon the  expiration of
the number of months, or other calendar periods, set forth above from said
date.  Said rent shall be payable monthly in advance.
4. EQUIPMENT AND LIABILITY.  LESSOR, at the request of LESSEE, has ordered or
shall order the EQUIPMENT described above from a supplier selected by LESSEE.
LESSOR shall not be liable for specific performance of this LEASE or for
damages, if , for any reason, supplier fails to accept such order or delays or
fails to fill the order.  LESSEE agrees to accept such EQUIPMENT and to
complete the acceptance notice provided by LESSOR.
5. PLACE OF USE; INSPECTION.  LESSEE shall keep the EQUIPMENT at its place of
business as specified above.  LESSEE covenants and agrees not to allow the use
of EQUIPMENT by other than the employees of the LESSEE and covenants and agrees
not to rent or sublet the EQUIPMENT or any part thereof to others for their own
use.  Whenever requested by LESSOR, LESSEE shall promptly advise LESSOR as to
the exact location of the EQUIPMENT.  LESSOR, from time to time, may enter the
premises where the EQUIPMENT is located and inspect same upon 1 business day's
notice and subject to LESSEE's security rules.
6. ADVANCE RENTALS.  At the LESSOR'S option any advance rentals made hereunder
may be applied by LESSOR to cure any default of LESSEE.  LESSEE will from time
to time promptly provide any additional credit or financial information that
the LESSOR deems necessary to this transaction.
7. DISCLAIMER OF WARRANTY.   LESSOR not being the manufacturer or the supplier
of the EQUIPMENT, nor a dealer in similar equipment, has not made and does not
make any representation warranty or covenant, express or implied, with respect
to the design, condition, durability, suitability, fitness for use or
merchantability of the EQUIPMENT in any respect.  As between LESSOR and LESSEE,
the EQUIPMENT shall be accepted and leased by LESSEE "AS IS" and "WITH ALL
FAULTS".  LESSEE agrees to settle all such claims directly with the supplier
and will not assert any such claims or defenses against LESSOR or LESSOR'S
assignee.  LESSOR assigns to, authorizes and appoints LESSEE to enforce, in its
own name and at its own expense, any claim, warranty, agreement or
representation which may be made against the supplier, but LESSOR assumes no
obligation as to the extent or enforceability thereof. LESSOR agrees to
cooperate with LESSEE in the enforcement of any manufacturer warranty to the
extent LESSOR'S cooperation is necessary under the terms of any such warranty.
No defect or unfitness of the EQUIPMENT, loss or damage thereto or any other
circumstances shall relieve LESSEE of its obligations under this LEASE which
are absolute and unconditional. In no event shall LESSOR or LESSEE be liable
for any consequential damages.  Supplier is not an agent of LESSOR and no
employee of supplier is authorized to waive, supplement or otherwise alter, any
provision of this LEASE.
8. ERRORS IN ESTIMATED COST.  The amount of each rent payment and the advance
rental initially set forth above are based upon the estimated total cost of the
EQUIPMENT (excluding taxes, transportation and any other charges) which is an
estimate, and each shall be adjusted proportionally if the actual cost of the
EQUIPMENT differs from said estimate.  LESSEE hereby authorizes LESSOR to
correct the figures set forth above when the actual cost is  known.  If the
actual cost of the EQUIPMENT differs from the estimated cost by more than ten
percent (10%) thereof, however, either party at its option may terminate this
LEASE by giving written notice to the other party within fifteen (15) days
after receiving notice of the actual cost or the corrected rent.
9. USE AND RETURN OF EQUIPMENT.  The LESSEE shall exercise due and proper care
in the use, repair and servicing of the EQUIPMENT and at all times and at its
expense shall keep and maintain the leased property in good working condition,
order, and repair.  LESSEE may alter and upgrade the EQUIPMENT provided that
such alteration or upgrade does not reduce the value or impair the capability
of the EQUIPMENT.  LESSEE shall have the right to remove any such alteration or
upgrade before returning the EQUIPMENT to LESSOR so long as the removal does
not damage the EQUIPMENT.  LESSEE shall bear all costs associated with the
acquisition, installation and removal of any such alteration or upgrade.  Upon
the expiration or termination of this LEASE, LESSEE at its sole expense shall
forthwith properly pack and return the EQUIPMENT to LESSOR, or to such place
designated by LESSOR within 30 miles of EQUIPMENT location, in the same
condition as when received by LESSEE, reasonable wear and tear alone excepted.
All replacement parts, incorporated in or affixed to the EQUIPMENT after the
commencement of this LEASE shall become the property of LESSOR.
10. TITLE; LIENS; TAXES.   The Equipment is, and shall at all times be and
remain (i) the sole and exclusive property of LESSOR; and the LESSEE shall have
no right, title or interest therein or thereto  except as expressly set forth
in this LEASE; (ii) personal property notwithstanding that the EQUIPMENT or any
part thereof may now be or hereafter become, in  any manner affixed or attached
to or imbedded in, or permanently resting upon, real property or any building
thereon.  LESSEE agrees to affix nameplates or decals to the EQUIPMENT
indicating LESSOR'S ownership thereof if requested and supplied by LESSOR.

LESSEE shall keep the EQUIPMENT free and clear of levies, liens and
encumbrances and shall pay all license and registration fees, assessments,
filing or recording fees, documentary stamp tax, sale/use taxes, personal
property taxes, gross receipt taxes, excise taxes including value added taxes
and all other taxes (local, state and federal) which may now or hereafter be
imposed upon the ownership, leasing, rental, sale, purchase, possession or use
of the EQUIPMENT whether assessed to LESSOR or LESSEE excluding, however, all
taxes on or measured by LESSOR'S net income.
     If such taxes are levied against the LESSOR, the LESSOR shall have the
right, subject to the following paragraph, but not the obligation, to pay any
such taxes, whether levied against the LESSOR or the LESSEE.  In such event the
LESSEE shall reimburse the LESSOR therefor within five (5) days after receipt
of invoice and for the failure to make such reimbursement when due the LESSOR
shall have all remedies provided herein with respect to the nonpayment of the
rental hereunder.  LESSEE shall give LESSOR immediate notice of any attachment
or other judicial process, liens or encumbrances affecting the EQUIPMENT and
shall indemnify and save LESSOR harmless from any loss or damage caused
thereby.
     Notwithstanding the foregoing, LESSEE shall have the right, at its expense
and by appropriate legal proceedings, to contest the validity, applicability or
amount of any fees, assessments or taxes imposed upon the EQUIPMENT provided
that LESSEE shall not cause a tax lien to be levied against the EQUIPMENT or
LESSOR.  LESSOR agrees to cooperate with LESSEE in any such contest and will
permit LESSEE to contest the same in the name of LESSOR (if required by law) or
in the name of LESSEE, all at LESSEE'S cost and expense.  The non-payment of
any fee, tax or assessment by LESSEE in connection with such contest shall not
be deemed a default hereunder until final determination of such contest and
expiration of any due date established therein.
11. FILING.  LESSEE hereby authorizes LESSOR to file financing statements with
respect to the EQUIPMENT or any collateral provided by LESSEE to LESSOR prior
to or following LESSOR's acceptance of this LEASE, in any State of the United
States in which the EQUIPMENT is located.  LESSEE shall execute such
supplemental instruments and financing statements if LESSOR  deems such to be
necessary or advisable and shall otherwise cooperate to defend the title of the
LESSOR by filing or  otherwise.  LESSEE, upon demand, shall promptly pay to
LESSOR all filing costs and fees incurred or paid by LESSOR.
12. INSURANCE.  Commencing on the date risk passes to LESSOR from the supplier
and continuing until LESSEE has redelivered possession of the EQUIPMENT to
LESSOR, LESSEE, at its expense, shall keep the EQUIPMENT insured against all
risks of loss or damage from every cause whatsoever for the greater of the
total rent for the full term of this LEASE or the full undepreciated
replacement value (new) of the EQUIPMENT, and shall carry public liability
insurance, both personal injury and property damage, covering the EQUIPMENT and
its use.  All insurance shall be of a type, form, in amounts, with companies
and contain terms and conditions reasonably satisfactory to LESSOR.
Certificates of insurance or other evidence satisfactory to LESSOR, including
the original or certified copies of the actual policies showing the existence
of insurance in accordance herewith, and the terms, conditions and payments
therefor shall be delivered to LESSOR upon LESSOR's request.  Said insurance
shall provide for loss, if any, payable to LESSOR and LESSEE as their interests
may appear and shall name LESSOR as an additional insured for purposes of
liability insurance.  The proceeds of insurance payable as a result of loss of
or damage to EQUIPMENT shall be applied, at the option of LESSEE: (a) toward
the replacement, restoration or repair of EQUIPMENT which may be lost, stolen,
destroyed or damaged; or (b) toward payment of the obligations of LESSEE
hereunder.  In the event the LESSEE elects to apply insurance proceeds to the
repair or to the replacement of the damaged EQUIPMENT, this LEASE shall
continue in full force and effect.  In the event LESSEE elects to apply
insurance proceeds to the payment of LESSEE'S obligations for rent hereunder,
the LESSEE's obligations for the rent hereunder shall be reduced by the amount
of such insurance proceeds, but the LESSEE shall be liable for any additional
rents due.  Such reduction of rents shall be allocated solely to the item or
items lost, stolen, damaged or destroyed.
13. LOSS; DAMAGE.  LESSEE assumes and shall bear the risk of loss and damage to
the EQUIPMENT from every cause whatsoever, whether or not insured.  In the
event of any loss or damage to the EQUIPMENT, LESSEE, at the option of LESSEE,
shall (a) place the same in good repair, condition and working order; or (b)
replace the same with new EQUIPMENT; or (c) immediately pay to LESSOR the
following amount:  the greater of (x) the total unpaid rentals for the entire
term hereof (discounted to present value at the rate of six (6) percent per
annum plus any amount due LESSOR pursuant to Section 18 hereof or (y) the fair
market value of the EQUIPMENT immediately prior to the loss or damage.  Upon
such payment, together with payment of all other sums owing on said LEASE to
and including such payment date, LESSOR will transfer title to the affected
EQUIPMENT to LESSEE "as is", "where is", and without warranty, express or
implied but including the warranty of good and marketable title.
14. INDEMNITY.  Lessee does hereby assume liability for and does agree to
indemnify, protect, save and keep harmless LESSOR, and any assignee of LESSOR
from and against any and all liabilities, losses, damages, penalties, claims,
actions, suits, costs, expenses and disbursements, including court costs and
reasonable legal expenses, of whatever kind and nature, imposed on, incurred by
or asserted against LESSOR, and any assignee of LESSOR (whether or not also
indemnified against by any other person) in any way relating to or arising out
of this LEASE or the manufacture, purchase, ownership, delivery, lease,
possession, use, operation, condition, return or other disposition of the
EQUIPMENT by LESSEE, including without limitation any claim alleging latent or
other defects, whether or not discoverable by LESSOR or LESSEE; any claim for
patent, trademark or copyright infringement; any claim arising out of strict
liability in tort; and any taxes for which LESSEE is responsible pursuant to
this LEASE, but excluding any such claims arising from acts or omissions of
LESSOR or its assignees.
15. DEFAULT.  Any of the following events or conditions shall constitute an
event of default hereunder; (a) LESSEE'S failure to pay when due any rent or
other amount due hereunder within 30 days after receipt by LESSEE of notice of
default: (b) LESSEE'S default in performing any other term, covenant or
condition hereof if such default is not cured within 30 days after receipt by
LESSEE of notice of default; (c) seizure of any EQUIPMENT under legal process;
(d) the filing by or against LESSEE of a petition for reorganization or
liquidation under the Bankruptcy Code or any amendment thereto or under any
other insolvency law providing for the relief of debtors; (e) the voluntary or
involuntary making of an assignment of a substantial portion of its assets by
LESSEE for the benefit of creditors, appointment of a receiver or trustee for
LESSEE or for any of LESSEE'S asset institution by or against LESSEE of any
formal or informal proceeding for dissolution, liquidation, settlement of
claims against or winding up of the affairs of LESSEE, or the making by LESSEE
of a transfer of all or a material portion of LESSEE's assets or inventory not
in the ordinary course of business and not for equivalent consideration.
16. REMEDIES.  Upon LESSEE'S default, LESSOR shall have the right to exercise
any one or more of the following remedies; (a) without affecting LESSOR'S title
or right to possession of the EQUIPMENT, declare due, sue for and recover all
rents and other amounts then accrued or thereafter accruing for the entire
lease term, discounted to present value at 8% per annum or the sum calculated
per paragraph 27 below, whichever is greater, (b) require LESSEE to promptly
redeliver the EQUIPMENT in the manner specified in Section 9 hereof; or (c)
repossess the EQUIPMENT without notice, legal process, prior judicial hearing
or liability for trespass (which rights LESSEE hereby voluntarily,
intelligently and knowingly waives).  Such return or repossession of EQUIPMENT
shall not terminate this LEASE unless LESSOR so notifies LESSEE in writing.
LESSOR, at its option may sell or re-lease the EQUIPMENT upon such terms as it
reasonably determines and apply the proceeds to LESSEE's obligations hereunder,
after deducting from such proceeds all costs and expenses of repossession and
disposition, reasonable attorney's fees, plus any amounts due LESSOR pursuant
to Section 18 hereof.  LESSEE shall promptly pay any resulting deficiency,
together with interest at the lesser of sixteen (16%) percent and LESSOR's
reasonable attorneys' fees if legal action is required to collect such
deficiency.  If LESSOR is unable to repossess the EQUIPMENT for any reason, the
EQUIPMENT shall be deemed a total loss and LESSEE shall pay to LESSOR the
amount due pursuant to Section 13 (c).  All such remedies are cumulative and
may be enforced separately or concurrently and are in addition to any other
rights or remedies available to LESSOR at law or in equity.  The foregoing
provisions of this Section 16 are subject to any mandatory requirement of
applicable law then in effect.
17. ASSIGNMENT.  Without the prior written consent of LESSOR, LESSEE shall not
assign, transfer, pledge or hypothecate this LEASE and EQUIPMENT or any
interest in this LEASE or in and to the EQUIPMENT or permit its rights under
this LEASE to be subject to any lien, charge or encumbrance of any nature.
Notwithstanding the foregoing, LESSEE may assign the LEASE, the EQUIPMENT and
its interest in this LEASE and the EQUIPMENT to an affiliate or in connection
with a sale of all or substantially all of its assets to, or consolidation with
or merger of LESSEE into, any entity so long as such entity assumes the
obligations of LESSEE hereunder and immediately following such event is, in the
reasonable opinion of LESSOR, no less creditworthy than was LESSEE immediately
prior to such event.  LESSOR shall have the right to assign this LEASE or any
part thereof.  If LESSOR assigns the rents reserved herein or all or any  of
the LESSOR's other rights hereunder, or amounts equal thereto, the right of the
assignee to receive the rentals as well as any other right of the assignee
shall not be subject to any defense, setoff, counterclaim or recoupment which
may arise out of any breach or obligation of LESSOR or by reason of any other
indebtedness or liability at any time owing by LESSOR to LESSEE.  All rentals
due hereunder shall be payable to assignee by LESSEE in accordance with the
terms hereof.  On receipt of notification of such assignment,  LESSEE, subject
to its rights hereunder, shall become the pledgeholder of the EQUIPMENT for and
on behalf of the assignee and will relinquish possession thereof only to the
assignee or pursuant to its written order subject to LESSEE's rights hereunder.
LESSEE, on receiving notice of any such assignment, shall make payments as may
therein be directed.  Following such assignments, the term "LESSOR"  shall be
deemed to include or refer to LESSOR'S assignee, provided that no such assignee
shall be deemed to assume any obligation or duty imposed upon LESSOR hereunder
and LESSEE shall look only to LESSOR for performance thereof.  There shall be
only one executed counterpart of this LEASE marked "Original" and all other
counterparts shall be marked "Duplicate".  To the extent that LEASE constitutes
chattel paper (as defined in the Uniform Commercial Code) no security interest
in this lease may be created through the transfer or possession of any
counterpart other than the original.
18. DEPRECIATION AND INVESTMENT TAX CREDIT INDEMNITY.  (THIS SECTION DOES NOT
APPLY IF LESSOR HAS AGREED IN WRITING TO PASS THE INVESTMENT TAX CREDIT (ITC)
TO LESSEE.)  If, as to any EQUIPMENT, under any circumstances and for any
reason whatsoever, except through the fault of the LESSOR, LESSOR shall lose or
shall not have the right to claim, or there shall be disallowed or recaptured
(collectively a "loss") (1) any portion of the maximum ITC, allowable under the
Internal Revenue Code of 1954, as amended, for new property with a useful life
equivalent to the lease term for such EQUIPMENT; or (2) any prortion of the
claimed depreciation deductions for such EQUIPMENT, based on the cost thereof,
LESSEE agrees to pay LESSOR upon demand an amount which, in the reasonable
opinion of LESSOR, will cause LESSOR's after tax net yield in respect of such
equipment to equal the net yield that LESSOR would have received if LESSOR had
not suffered such loss.

GENTLEMEN:

As Lessee under the lease referred to above with International Financial
Services Corporation, the undersigned hereby acknowledges the Lessor's right to
assign its interest under the Lease and that Assignee does not assume any of
the obligations of the Lessor thereunder, consents to any such assignment and,
in consideration of the assignee having advanced funds to the Lessor to finance
the equipment described in the Lease, and in consideration of Assignee's
covenant with Lessee that so long as Lessee is not in default under the Lease,
Lessee will quietly possess the Equipment, free of interference from third
parties, agrees as follows: (a) that its obligation to pay directly to the
Assignee the amounts (whether designated as rentals or otherwise) which become
due from the Lessee as set forth in the Lease so assigned shall be absolutely
unconditional and shall be payable in strict accordance with the Lease, and it
promises so to pay the same notwithstanding any defense, set-off or
counterclaim whatsoever, whether by reason of breach of the Lease, the exercise
of any right or option thereunder, or otherwise, which it may or might now or
hereafter have as against the Lessor (the Lessee reserving its right to have
recourse directly against the Lessor on account of any such defense, set-off or
counterclaim); and (b) that, subject to and without impairment of the Lessee's
leasehold rights in and to the Equipment described in said Lease, Lessee holds
said Equipment and the possession thereof for the Assignee to the extent of the
Assignee's rights therein.  There shall be only one executed counterpart of
this lease marked "Original" and all other counterparts shall be marked

rental initially set forth above are based upon the estimated total cost of the
EQUIPMENT (excluding taxes, transportation and any other charges) which is an
estimate, and each shall be adjusted proportionally if the actual cost of the
EQUIPMENT differs from said estimate.  LESSEE hereby authorizes LESSOR to
correct the figures set forth above when the actual cost is  known.  If the
actual cost of the EQUIPMENT differs from the estimated cost by more than ten
percent (10%)thereof, however, either party at its option may terminate this
LEASE by giving written notice to the other party within fifteen (15) days
after receiving notice of the actual cost or the corrected rent.

LESSEE shall keep the EQUIPMENT free and clear of levies, liens and
encumbrances and shall pay all license and registration fees, assessments,
filing or recording fees, documentary stamp tax, sale/use taxes, personal
property taxes, gross receipt taxes, excise taxes including value added taxes
and all other taxes (local, state and federal) which may now or hereafter be
imposed upon the ownership, leasing, rental, sale, purchase, possession or use
of the EQUIPMENT whether assessed to LESSOR or LESSEE excluding, however, all
taxes on or measured by LESSOR'S net income.
     If such taxes are levied against the LESSOR, the LESSOR shall have the
right, subject to the following paragraph, but not the obligation, to pay any
such taxes, whether levied against the LESSOR or the LESSEE.  In such event the
LESSEE shall reimburse the LESSOR therefor within five (5) days after receipt
of invoice and for the failure to make such reimbursement when due the LESSOR
shall have all remedies provided herein with respect to the nonpayment of the
rental hereunder.  LESSEE shall give LESSOR immediate notice of any attachment
or other judicial process, liens or encumbrances affecting the EQUIPMENT and
shall indemnify and save LESSOR harmless from any loss or damage caused
thereby.
     Notwithstanding the foregoing, LESSEE shall have the right, at its expense
and by appropriate legal proceedings, to contest the validity, applicability or
amount of any fees, assessments or taxes imposed upon the EQUIPMENT provided
that LESSEE shall not cause a tax lien to be levied against the EQUIPMENT or
LESSOR.  LESSOR agrees to cooperate with LESSEE in any such contest and will
permit LESSEE to contest the same in the name of LESSOR (if required by law) or
in the name of LESSEE, all at LESSEE'S cost and expense.  The non-payment of
any fee, tax or assessment by LESSEE in connection with such contest shall not
be deemed a default hereunder until final determination of such contest and
expiration of any due date established therein.
11. FILING.  LESSEE hereby authorizes LESSOR to file financing statements with
respect to the EQUIPMENT or any collateral provided by LESSEE to LESSOR prior
to or following LESSOR's acceptance of this LEASE, in any State of the United
States in which the EQUIPMENT is located.  LESSEE shall execute such
supplemental instruments and financing statements if LESSOR  deems such to be
necessary or advisable and shall otherwise cooperate to defend the title of the
LESSOR by filing or  otherwise.  LESSEE, upon demand, shall promptly pay to
LESSOR all filing costs and fees incurred or paid by LESSOR.
12. INSURANCE.  Commencing on the date risk passes to LESSOR from the supplier
and continuing until LESSEE has redelivered possession of the EQUIPMENT to
LESSOR, LESSEE, at its expense, shall keep the EQUIPMENT insured against all
risks of loss or damage from every cause whatsoever for the greater of the
total rent for the full term of this LEASE or the full undepreciated
replacement value (new) of the EQUIPMENT, and shall carry public liability
insurance, both personal injury and property damage, covering the EQUIPMENT and
its use.  All insurance shall be of a type, form, in amounts, with companies
and contain terms and conditions reasonably satisfactory to LESSOR.
Certificates of insurance or other evidence satisfactory to LESSOR, including
the original or certified copies of the actual policies showing the existence
of insurance in accordance herewith, and the terms, conditions and payments
therefor shall be delivered to LESSOR upon LESSOR's request.  Said insurance
shall provide for loss, if any, payable to LESSOR and LESSEE as their interests
may appear and shall name LESSOR as an additional insured for purposes of
liability insurance.  The proceeds of insurance payable as a result of loss of
or damage to EQUIPMENT shall be applied, at the option of LESSEE: (a) toward
the replacement, restoration or repair of EQUIPMENT which may be lost, stolen,
destroyed or damaged; or (b) toward payment of the obligations of LESSEE
hereunder.  In the event the LESSEE elects to apply insurance proceeds to the
repair or to the replacement of the damaged EQUIPMENT, this LEASE shall
continue in full force and effect.  In the event LESSEE elects to apply
insurance proceeds to the payment of LESSEE'S obligations for rent hereunder,
the LESSEE's obligations for the rent hereunder shall be reduced by the amount
of such insurance proceeds, but the LESSEE shall be liable for any additional
rents due.  Such reduction of rents shall be allocated solely to the item or
items lost, stolen, damaged or destroyed.
13. LOSS; DAMAGE.  LESSEE assumes and shall bear the risk of loss and damage to
the EQUIPMENT from every cause whatsoever, whether or not insured.  In the
event of any loss or damage to the EQUIPMENT, LESSEE, at the option of LESSEE,
shall (a) place the same in good repair, condition and working order; or (b)
replace the same with new EQUIPMENT; or (c) immediately pay to LESSOR the
following amount:  the greater of (x) the total unpaid rentals for the entire
term hereof (discounted to present value at the rate of six (6) percent per
annum plus any amount due LESSOR pursuant to Section 18 hereof or (y) the fair
market value of the EQUIPMENT immediately prior to the loss or damage.  Upon
such payment, together with payment of all other sums owing on said LEASE to
and including such payment date, LESSOR will transfer title to the affected
EQUIPMENT to LESSEE "as is", "where is", and without warranty, express or
implied but including the warranty of good and marketable title.
14. INDEMNITY.  Lessee does hereby assume liability for and does agree to
indemnify, protect, save and keep harmless LESSOR, and any assignee of LESSOR
from and against any and all liabilities, losses, damages, penalties, claims,
actions, suits, costs, expenses and disbursements, including court costs and
reasonable legal expenses, of whatever kind and nature, imposed on, incurred by
or asserted against LESSOR, and any assignee of LESSOR (whether or not also
indemnified against by any other person) in any way relating to or arising out
of this LEASE or the manufacture, purchase, ownership, delivery, lease,
possession, use, operation, condition, return or other disposition of the
EQUIPMENT by LESSEE, including without limitation any claim alleging latent or
other defects, whether or not discoverable by LESSOR or LESSEE; any claim for
patent, trademark or copyright infringement; any claim arising out of strict
liability in tort; and any taxes for which LESSEE is responsible pursuant to
this LEASE, but excluding any such claims arising from acts or omissions of
LESSOR or its assignees.
15. DEFAULT.  Any of the following events or conditions shall constitute an
event of default hereunder; (a) LESSEE'S failure to pay when due any rent or
other amount due hereunder within 30 days after receipt by LESSEE of notice of
default: (b) LESSEE'S default in performing any other term, covenant or
condition hereof if such default is not cured within 30 days after receipt by
LESSEE of notice of default; (c) seizure of any EQUIPMENT under legal process;
(d) the filing by or against LESSEE of a petition for reorganization or
liquidation under the Bankruptcy Code or any amendment thereto or under any
other insolvency law providing for the relief of debtors; (e) the voluntary or
involuntary making of an assignment of a substantial portion of its assets by
LESSEE for the benefit of creditors, appointment of a receiver or trustee for
LESSEE or for any of LESSEE'S asset institution by or against LESSEE of any
formal or informal proceeding for dissolution, liquidation, settlement of
claims against or winding up of the affairs of LESSEE, or the making by LESSEE
of a transfer of all or a material portion of LESSEE's assets or inventory not
in the ordinary course of business and not for equivalent consideration.
16. REMEDIES.  Upon LESSEE'S default, LESSOR shall have the right to exercise
any one or more of the following remedies; (a) without affecting LESSOR'S title
or right to possession of the EQUIPMENT, declare due, sue for and recover all
rents and other amounts then accrued or thereafter accruing for the entire
lease term, discounted to present value at 8% per annum or the sum calculated
per paragraph 27 below, whichever is greater, (b) require LESSEE to promptly
redeliver the EQUIPMENT in the manner specified in Section 9 hereof; or (c)
repossess the EQUIPMENT without notice, legal process, prior judicial hearing
or liability for trespass (which rights LESSEE hereby voluntarily,
intelligently and knowingly waives).  Such return or repossession of EQUIPMENT
shall not terminate this LEASE unless LESSOR so notifies LESSEE in writing.
LESSOR, at its option may sell or re-lease the EQUIPMENT upon such terms as it
reasonably determines and apply the proceeds to LESSEE's obligations hereunder,
after deducting from such proceeds all costs and expenses of repossession and
disposition, reasonable attorney's fees, plus any amounts due LESSOR pursuant
to Section 18 hereof.  LESSEE shall promptly pay any resulting deficiency,
together with interest at the lesser of sixteen (16%) percent and LESSOR's
reasonable attorneys' fees if legal action is required to collect such
deficiency.  If LESSOR is unable to repossess the EQUIPMENT for any reason, the
EQUIPMENT shall be deemed a total loss and LESSEE shall pay to LESSOR the
amount due pursuant to Section 13 (c).  All such remedies are cumulative and
may be enforced separately or concurrently and are in addition to any other
rights or remedies available to LESSOR at law or in equity.  The foregoing
provisions of this Section 16 are subject to any mandatory requirement of
applicable law then in effect.
17. ASSIGNMENT.  Without the prior written consent of LESSOR, LESSEE shall not
assign, transfer, pledge or hypothecate this LEASE and EQUIPMENT or any
interest in this LEASE or in and to the EQUIPMENT or permit its rights under
this LEASE to be subject to any lien, charge or encumbrance of any nature.
Notwithstanding the foregoing, LESSEE may assign the LEASE, the EQUIPMENT and
its interest in this LEASE and the EQUIPMENT to an affiliate or in connection
with a sale of all or substantially all of its assets to, or consolidation with
or merger of LESSEE into, any entity so long as such entity assumes the
obligations of LESSEE hereunder and immediately following such event is, in the
reasonable opinion of LESSOR, no less creditworthy than was LESSEE immediately
prior to such event.  LESSOR shall have the right to assign this LEASE or any
part thereof.  If LESSOR assigns the rents reserved herein or all or any  of
the LESSOR's other rights hereunder, or amounts equal thereto, the right of the
assignee to receive the rentals as well as any other right of the assignee
shall not be subject to any defense, setoff, counterclaim or recoupment which
may arise out of any breach or obligation of LESSOR or by reason of any other
indebtedness or liability at any time owing by LESSOR to LESSEE.  All rentals
due hereunder shall be payable to assignee by LESSEE in accordance with the
terms hereof.  On receipt of notification of such assignment,  LESSEE, subject
to its rights hereunder, shall become the pledgeholder of the EQUIPMENT for and
on behalf of the assignee and will relinquish possession thereof only to the
assignee or pursuant to its written order subject to LESSEE's rights hereunder.
LESSEE, on receiving notice of any such assignment, shall make payments as may
therein be directed.  Following such assignments, the term "LESSOR"  shall be
deemed to include or refer to LESSOR'S assignee, provided that no such assignee
shall be deemed to assume any obligation or duty imposed upon LESSOR hereunder
and LESSEE shall look only to LESSOR for performance thereof.  There shall be
only one executed counterpart of this LEASE marked "Original" and all other
counterparts shall be marked "Duplicate".  To the extent that LEASE constitutes
chattel paper (as defined in the Uniform Commercial Code) no security interest
in this lease may be created through the transfer or possession of any
counterpart other than the original.
18. DEPRECIATION AND INVESTMENT TAX CREDIT INDEMNITY.  (THIS SECTION DOES NOT
APPLY IF LESSOR HAS AGREED IN WRITING TO PASS THE INVESTMENT TAX CREDIT (ITC)
TO LESSEE.)  If, as to any EQUIPMENT, under any circumstances and for any
reason whatsoever, except through the fault of the LESSOR, LESSOR shall lose or
shall not have the right to claim, or there shall be disallowed or recaptured
(collectively a "loss") (1) any portion of the maximum ITC, allowable under the
Internal Revenue Code of 1954, as amended, for new property with a useful life
equivalent to the lease term for such EQUIPMENT; or (2) any prortion of the
claimed depreciation deductions for such EQUIPMENT, based on the cost thereof,
LESSEE agrees to pay LESSOR upon demand an amount which, in the reasonable
opinion of LESSOR, will cause LESSOR's after tax net yield in respect of such
equipment to equal the net yield that LESSOR would have received if LESSOR had
not suffered such loss.

of the EQUIPMENT against all claims and liens of LESSOR'S creditors.  Upon
expiration of the term of this LEASE and exercise by LESSEE of its purchase
option, LESSOR shall transfer title to the EQUIPMENT to LESSEE pursuant to a

INTERNATIONAL FINANCIAL SERVICES CORPORATION
1113 Milwaukee Avenue
Libertyville, IL  60048


GENTLEMEN:

As Lessee under the lease referred to above with International Financial
Services Corporation, the undersigned hereby acknowledges the Lessor's right to
assign its interest under the Lease and that Assignee does not assume any of
the obligations of the Lessor thereunder, consents to any such assignment and,
in consideration of the assignee having advanced funds to the Lessor to finance
the equipment described in the Lease, and in consideration of Assignee's
covenant with Lessee that so long as Lessee is not in default under the Lease,
Lessee will quietly possess the Equipment, free of interference from third
parties, agrees as follows: (a) that its obligation to pay directly to the
Assignee the amounts (whether designated as rentals or otherwise) which become
due from the Lessee as set forth in the Lease so assigned shall be absolutely
unconditional and shall be payable in strict accordance with the Lease, and it
promises so to pay the same notwithstanding any defense, set-off or
counterclaim whatsoever, whether by reason of breach of the Lease, the exercise
of any right or option thereunder, or otherwise, which it may or might now or
hereafter have as against the Lessor (the Lessee reserving its right to have
recourse directly against the Lessor on account of any such defense, set-off or
counterclaim); and (b) that, subject to and without impairment of the Lessee's
leasehold rights in and to the Equipment described in said Lease, Lessee holds
said Equipment and the possession thereof for the Assignee to the extent of the
Assignee's rights therein.  There shall be only one executed counterpart of
this lease marked "Original" and all other counterparts shall be marked

Mebane, North Carolina, wishes to guarantee unconditionally all of NSI's
obligations under the restated and amended agreement.

         NOW, THEREFORE, for and in consideration of the premises and the
mutual covenants and agreements hereinafter set forth, the sufficiency of which
is hereby acknowledged, NSI and SigmaTron agree to amend and restate the 1995
Agreement in its entirety as follows:

1.       DEFINITION OF CO DETECTORS; TERM OF AGREEMENT:

         (a)     This Amended and Restated Agreement provides for the
                 manufacture and assembly by SigmaTron of the models of devices
                 that detect indoor levels of carbon monoxide gas set forth on
                 Exhibit A to this Agreement and all comparable or replacement
                 models now and hereafter designed, manufactured or sold by NSI
                 (all such models and products shall be referred to
                 collectively as "CO DETECTORS" and singly as a "CO DETECTOR").
                 A comparable or replacement model is defined as a CO detector
                 that utilizes similar sensing technology, assembly equipment
                 and tooling to
<PAGE>   2
                 manufacture as the models listed on Exhibit A.  NSI
                 shall amend Exhibit A as comparable and replacement models are
                 released and obsolete models discontinued.  If at any time
                 during the Term, NSI plans to design, manufacture or sell a CO
                 detector that is not a replacement of or comparable to CO
                 Detectors, SigmaTron shall have the right to submit to NSI a
                 bid to manufacture and assemble such CO detector and to match
                 any competing bid received by NSI for the manufacture and
                 assembly of such CO detector.  NSI shall provide SigmaTron
                 with such information as necessary to enable SigmaTron to
                 formulate its bids and a reasonable time in which to respond
                 to any competing bid.  Should NSI determine that SigmaTron is
                 unable to match such bid, then NSI shall be free to accept the
                 competing bid, free of claim by SigmaTron hereunder.  If NSI
                 accepts SigmaTron's bid for said CO detector, said CO detector
                 shall be added to Exhibit A to this Agreement and shall be
                 considered "CO Detectors" hereunder.

         (b)     Subject to termination pursuant to Sections 1(c) and 13 below
                 and subject to the last sentence of this subparagraph, this
                 Agreement shall be for an initial period which shall expire on
                 June 9, 1998.  Each party shall give the other party a notice
                 of its desire regarding renewal or nonrenewal at least 6
                 months before the expiration of the initial period (or a
                 renewal period), whereupon the parties shall negotiate the
                 terms and conditions applicable during the renewal period, to
                 be effective upon expiration of the current period.  (The
                 initial and any renewal period shall be referred to as the
                 "TERM").  If after such negotiations, the terms and conditions
                 are not acceptable to a party, then the party for whom the
                 terms and conditions are not acceptable, in its sole
                 discretion, may cause the Agreement to terminate (without
                 liability by reason of such termination) by delivery of a
                 written notice to that effect, in which case the initial
                 period or renewal period shall not expire until six months
                 after receipt by the other party of such notice.

         (c)     The parties acknowledge that, during the course of their
                 relationship, issues may arise as to the terms and conditions
                 of this Agreement and other aspects of their working
                 relationship.  The parties agree to meet, upon ten days' prior
                 written notice, no less often than once per quarter to discuss
                 their business relationship.  At the meeting, either party may
                 give to the other party written notice of an unresolved
                 concern relating to this Agreement, which notice shall specify
                 the nature of the concern and the notifying party's suggested
                 resolution.  The recipient of such notice shall provide the
                 notifying party a written response within 15 days of





                                      2
<PAGE>   3
                 receipt of the notice.  If the response is not
                 acceptable to the notifying party in its sole discretion, the
                 notifying party shall have the right to terminate this
                 Agreement upon no less than 6 months' prior written notice, by
                 giving written notice of termination within 15 days after
                 receipt of the recipient's written response.

2.       PURCHASE AND DELIVERY OF CO DETECTORS:

         (a)     NSI shall order CO Detectors from SigmaTron by executing and
                 delivering to SigmaTron a Master Production Schedule ("MPS").
                 On or before the first day of each month during the Term, NSI
                 will deliver to SigmaTron a MPS specifying NSI's requirements
                 and schedule for Delivery (as defined in Section 2(c)) for the
                 next succeeding three-month period (the "FIRM ORDER PERIOD")
                 and a forecast of orders for the nine-month period following
                 the Firm Order Period provided on a monthly basis (the
                 "FORECAST PERIOD").  Within thirty days thereafter, SigmaTron
                 will deliver to NSI a written acknowledgement of receipt and
                 approval of the MPS.  Subject to Section 2(b), the quantities
                 and schedule for Delivery during the Firm Order Period may not
                 be amended by NSI without the prior written consent of
                 SigmaTron.  Upon SigmaTron's receipt and approval of a MPS,
                 SigmaTron agrees to manufacture and Deliver and NSI shall be
                 obligated to accept Delivery and pay the Price (as defined in
                 Section 5) for the CO Detectors to be Delivered during the
                 Firm Order Period.  Further, NSI shall be obligated, every
                 Monday, to accept Delivery of and pay the Price pursuant to
                 Section 5 for, at a minimum, all units of CO Detectors
                 completed during the prior calendar week in accordance with
                 the MPS.

         (b)     NSI may reschedule the quantity of CO Detectors to be
                 Delivered during each month of a Firm Order Period only as
                 follows:

                       Month in                 Permitted
                      Firm Order                 Variance
                        Period 
                                              (+)       (-)
                     -------------           ----------------
                         [S]                 [C]       [C]

                         2nd                   0        15%
                 
                         3rd                  10%       30%

                 Any variations beyond the permitted variances shall be subject
                 to written acceptance by each of the parties.  Neither party
                 will be





                                      3
<PAGE>   4
                 obligated to accept a variance beyond a permitted variance.

         (c)     Delivery shall be deemed to occur upon the delivery by
                 SigmaTron to NSI's designated common carrier of finished CO
                 Detectors packaged for sale to the ultimate user, F.O.B.
                 SigmaTron's Del Rio, Texas warehouse ("DELIVERY").  NSI will
                 provide shipping instructions to SigmaTron in advance.  Except
                 for Deliveries either made to satisfy NSI's obligations
                 described in the last sentence of Section 2(a) or otherwise
                 directed by NSI, SigmaTron will ship in full truck quantities
                 only.

         (d)     All NSI owned machinery and equipment, tooling, test chambers
                 and fixtures to be utilized in SigmaTron's manufacture and
                 assembly of CO Detectors (the "NSI EQUIPMENT") shall be
                 delivered to Del Rio, Texas by NSI at NSI's expense.  Where
                 practicable, NSI will conspicuously mark each item of NSI
                 Equipment prior to delivery to SigmaTron with the following
                 statement:  "This equipment is owned by Nighthawk Systems,
                 Incorporated."  SigmaTron agrees it shall not remove, modify
                 or cover any such statement.  NSI shall be responsible to
                 insure the NSI Equipment against property damage in an amount
                 not less than the replacement cost thereof, which insurance
                 shall comply with the terms of the second and third sentences
                 of Section 12 hereof.  Said insurance shall cover the NSI
                 Equipment whether located in the United States or Mexico and
                 whether located at the facilities of SigmaTron or a third
                 party, such as an approved vendor.  All non-recurring charges
                 for tooling, testing and agency certification shall be paid
                 for by NSI.

3.       EXCLUSIVITY:

         (a)     Subject to Sections 3(b) and 3(c) below, NSI shall purchase
                 from SigmaTron all of NSI's requirements for CO Detectors for
                 resale in North America.

         (b)     If at any time during the Term, NSI's anticipated demand for
                 any month during the Firm Order Period or the Forecast Period
                 is greater than 300,000 CO Detectors, or if NSI's aggregate
                 purchases for the Firm Order Period and Forecast Period (taken
                 together) is greater than 2,000,000 CO Detectors, NSI may
                 request that SigmaTron provide assurances that it has the
                 capacity to meet NSI's requirements.  If SigmaTron's
                 assurances to NSI do not satisfy NSI in NSI's reasonable
                 discretion that SigmaTron has the capacity to meet NSI's
                 requirements, NSI may obtain a second supplier to provide to
                 NSI CO Detectors to meet the excess





                                      4
<PAGE>   5
                 demand only for the period of such excess demand.

         (c)     NSI's obligation to purchase CO Detectors from SigmaTron shall
                 not apply to indoor carbon monoxide gas detectors manufactured
                 by a third party that is acquired by NSI, Guarantor or
                 Williams Holding P.L.C.  during the Term.

4.       STORAGE AND RISK OF LOSS:

         SigmaTron shall store all CO Detectors in its Del Rio, Texas
         warehouse.  The risk of loss for CO Detectors shall be the
         responsibility of SigmaTron until Delivery to NSI's carrier has been
         completed.  SigmaTron agrees to provide security for the CO Detectors
         stored in its Del Rio, Texas warehouse consistent with SigmaTron's
         past practices.

5.       PRICE; PAYMENT:

         (a)     NSI agrees to pay SigmaTron for each CO Detector Delivered to
                 NSI hereunder a purchase price ("PRICE") determined in
                 accordance with a separate agreement (the "Side Agreement")
                 dated November 15, 1996, the terms of which have been agreed
                 upon between the parties.

         (b)     Prices in the Side Agreement are quoted in U.S. dollars F.O.B.
                 SigmaTron's warehouse Del Rio, Texas.

                 customs duties relating to the transfer of property from
                 Mexico to the United States are the responsibility of
                 SigmaTron and that all other property, sales, use or other
                 taxes assessed on the manufacture, storage or sale of CO
                 Detectors are the responsibility of NSI; provided, however,
                 that SigmaTron is responsible for taxes assessed on its
                 manufacturing operation in Mexico.  The party responsible for
                 any such duties or taxes shall cause to be filed all returns
                 and reports required in connection with such duties or taxes
                 and shall indemnify and hold the other party harmless with
                 respect to such duties or taxes, as the case may be.

         (d)     Payment shall be received by SigmaTron on or before 60 days
                 after the date of SigmaTron's delivery of invoices to NSI.

                 1/2% per month on any sum not received by SigmaTron on or
                 before 60 days after the date of delivery of SigmaTron's
                 invoice.

6.       CHANGE NOTICES; OBSOLETE INVENTORY:

         (a)     NSI may request changes of the models or to specifications for
                 CO Detectors by delivering to SigmaTron a change notice
                 ("Change Notice") describing the changes and the proposed
                 effective date of such changes.  Any increase or decrease in
                 the Bill of Material Cost of, or direct labor time required

7.       APPROVED VENDOR LIST:

         (a)     SigmaTron shall procure all components, materials and supplies
                 necessary for the assembly and manufacture of CO Detectors
                 from such third parties as have been approved in advance by
                 NSI as described on NSI's approved vendor list ("AVL").
                 SigmaTron will not procure any components, materials or
                 supplies for any model of CO Detector prior to receiving NSI's
                 final bill of material, including AVL, for that model.  NSI
                 may change the AVL in its sole discretion and such changes
                 shall be effective as directed by NSI.  SigmaTron and NSI
                 agree that any such changes that result in a change of model
                 or specification shall be treated as a Change Notice in
                 accordance with Section 6.

         (b)     SigmaTron shall not substitute any component, material or
                 supply without NSI's prior written consent, which consent may
                 be withheld in the exercise of NSI's sole discretion. Should
                 SigmaTron become aware of opportunities for the realization of
                 savings in component costs or direct labor costs, SigmaTron
                 shall inform NSI in writing.  NSI shall conduct such
                 investigation as it may desire and shall decide, in the
                 exercise of its sole discretion, whether or not to proceed so
                 as to take advantage of the





                                      7

                 suggestion.  Any cost savings realized because of changes
                 initially suggested to NSI by SigmaTron shall be shared by NSI
                 and SigmaTron on a 50/50 basis for the first 12 months after
                 the commencement of the cost savings realization.  Thereafter,
                 the benefit of all such cost savings shall be enjoyed by NSI
                 solely.

         (c)     SigmaTron shall invoice NSI for SigmaTron's share of such cost
                 savings within 5 days after the end of each month for which
                 SigmaTron is entitled to share in cost savings.

         (d)     Any effect that cost savings may have on Price shall be
                 processed in a Change Notice under Section 6.

         (e)     NSI may inspect SigmaTron's accounting and purchasing records
                 related to SigmaTron's purchase of components, materials and
                 supplies necessary for the assembly and manufacture of CO
                 Detectors, during SigmaTron's regular business hours, at
                 SigmaTron's Elk Grove Village offices, upon two (2) business
                 days notice to SigmaTron.  All such records are SigmaTron's
                 Confidential Information subject to the provisions of Section
                 11 of this Agreement.

8.       ACCEPTANCE, TESTING AND REJECTION:

         (a)     The basic acceptance criteria shall be conformance to the
                 drawings, specifications and test criteria specified by  NSI.

         (b)     SigmaTron shall conduct all quality assurance, burn-in and
                 tests required by NSI for each CO Detector and conform each CO
                 Detector to requirements of Underwriters' Laboratories ("UL")
                 as specified by NSI.  All tests shall be conducted by
                 SigmaTron at its plant that has been dedicated to the final
                 assembly and testing of CO Detectors.  SigmaTron further
                 agrees that said plant and its warehouse in Del Rio, Texas
                 shall be available for inspection by NSI and UL as desired.
                 Such inspections shall be conducted only during regular
                 business hours and subject to compliance with SigmaTron's
                 reasonable security requirements.

         (c)     NSI may reject lots of CO Detectors based on its reasonable
                 quality control methods of testing individual units.  In the
                 event of such rejection, SigmaTron shall be responsible for
                 the freight cost for shipping the rejected units back to
                 SigmaTron and for the cost of retesting any lots so rejected.

         (d)     SigmaTron agrees that its Mexican manufacturing operations
                 will





                                      8

                 obtain ISO 9000 certification no later than July 1, 1997.

9.       WARRANTY:

         (a)     The parties acknowledge that NSI is solely responsible for the
                 design and specifications of CO Detectors.  SigmaTron warrants
                 to NSI that each CO Detector will meet NSI's applicable
                 specifications and will function in accordance with those
                 specifications when Delivered. SigmaTron further warrants to
                 NSI that each CO Detector will be free from defects in
                 workmanship for a period of five years from the date of
                 manufacture.  SigmaTron will stamp a manufacture date code on
                 each CO Detector in order to create a reference date for such
                 purpose.  SigmaTron does not warrant the functionality of the
                 design or specifications of any CO Detector, and does not
                 warrant any components, materials or supplies against defects
                 unless the defects are readily discoverable upon inspection.
                 These warranties shall not apply and SigmaTron is not
                 responsible for defects in any CO Detector that has been
                 subject to improper handling, misuse, accident, negligence,
                 exposure to casualty or the elements, has been operated in
                 excess of conditions specified for the CO Detector or has been
                 altered or repaired in an unauthorized manner.  These
                 warranties are not assignable by NSI.

         (b)     The parties agree that NSI shall be solely responsible for any
                 warranty service of CO Detectors.  To the extent that a CO
                 Detector is returned to NSI by its customer because it is
                 defective and the defect resulted from a breach by SigmaTron
                 of its warranty as set forth in Section 9(a) above or
                 SigmaTron's failure to use components, materials or supplies
                 from the AVL, NSI shall be credited with the full Price paid
                 to SigmaTron for the defective CO Detector plus NSI's
                 reasonable out-of-pocket costs associated with the return and
                 handling of the defective CO Detector not to exceed $3.00 per
                 returned CO Detector.  A CO Detector shall not be considered
                 defective for purposes of this credit unless NSI has returned
                 it to SigmaTron for inspection and verification.  No defective
                 CO Detector so returned to SigmaTron shall be resold to NSI as
                 a new unit.

         (c)     Unless the claim is primarily attributable to SigmaTron within
                 the meaning of the following sentence, NSI shall indemnify and
                 hold SigmaTron harmless from any losses, claims (including
                 product liability claims) and costs, including court costs and
                 attorneys' fees, which arise from claims of third parties
                 based upon the use, sale, design, specifications, or operation
                 of CO Detectors.

                 SigmaTron shall indemnify and hold harmless NSI from any
                 losses, claims, liabilities and costs, including court costs
                 and attorneys' fees, which arise from claims of third parties
                 which are primarily attributable to SigmaTron, namely arising
                 out of a breach by SigmaTron of its warranty as set forth in
                 Section 9(a) above or a failure by SigmaTron to use
                 components, materials or supplies from the AVL.  The foregoing
                 indemnities shall be limited to $5,000,000 per claim.  In the
                 event a third party proceeds against both SigmaTron and NSI in
                 an action that may result in indemnification rights under
                 either of the first two sentences of this Section 9(c), each
                 of SigmaTron and NSI shall defend itself in that action and
                 cooperate in the defense to the fullest extent possible
                 without adversely affecting its interests, and SigmaTron and
                 NSI agree not to assert cross-claims in the resulting
                 arbitration, mediation or litigation.  The preceding sentence
                 shall not be construed as a waiver of the right to assert any
                 claim against the other in a different action.  If NSI and
                 SigmaTron cannot agree as to which indemnification applies,
                 that question shall be resolved by arbitration pursuant to
                 Section 17(h).

         (d)     NOTWITHSTANDING SECTION 13(e) BELOW, NSI'S REMEDIES UNDER
                 SECTION 9(b) FOR SIGMATRON'S BREACH OF WARRANTY ARE EXCLUSIVE
                 OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, AND SIGMATRON
                 HEREBY SPECIFICALLY DISCLAIMS ANY EXPRESS OR IMPLIED WARRANTY
                 OF ANY TYPE, INCLUDING WITHOUT LIMITATION THE WARRANTY OF
                 MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR USE OR PURPOSE.

10.      SAFETY STOCK:

         (a)     In recognition of the potential for unexpected fluctuations in
                 NSI's customers' demands for CO Detectors, when requested in
                 writing by NSI to do so, SigmaTron agrees to keep in its Del
                 Rio, Texas, warehouse an inventory equal to 20,000 units of
                 finished CO Detectors and 30,000 complete raw material CO
                 Detector kits (collectively, "SAFETY STOCK").  Prior to
                 Delivery, the Safety Stock shall be owned by SigmaTron.
                 SigmaTron shall bear the risk of loss with respect to Safety
                 Stock prior to Delivery.  NSI may request delivery of Safety
                 Stock as follows:

                 (i)      finished CO Detectors may be requested at any time
                          with no lead time constraints.  SigmaTron shall
                          Deliver the requested CO Detectors within 48 hours
                          after SigmaTron's receipt of NSI's request;





                                      10
<PAGE>   11
                 (ii)     finished CO Detectors assembled from the raw material
                          kits shall be Delivered by SigmaTron to NSI within 5
                          weeks of NSI's request.

         (b)     NSI shall pay SigmaTron the Price for CO Detectors Delivered
                 from Safety Stock.

         (c)     Any depletion in required levels of Safety Stock shall be
                 replenished by SigmaTron as soon as reasonably possible.
                 Deliveries of CO Detectors from Safety Stock are in addition
                 to Deliveries scheduled for any Firm Order Period.

11.      CONFIDENTIALITY:

         (a)     During the course of their business relationship described in
                 this Agreement and for three years thereafter, each party
                 shall disclose to the other party confidential and proprietary
                 information, including without limitation financial
                 information, (all of such information being referred to herein
                 as "Confidential Information"), the unauthorized disclosure of
                 which may adversely affect the competitive advantage of the
                 disclosing party.  Therefore, each of NSI and SigmaTron hereby
                 agrees that it shall maintain the Confidential Information of
                 the other party in strictest confidence and use such
                 Confidential Information only to fulfill its obligations to
                 the other party under this Agreement or as otherwise permitted
                 under this Agreement and shall not disclose Confidential
                 Information to any third party without the prior written
                 consent of the owner; provided however, that either party may
                 disclose Confidential Information of the other to lenders,
                 accountants, counsel, and other third parties with a duty of
                 confidentiality to the disclosing party, as long as such
                 disclosing party takes reasonable efforts to require such
                 third parties to keep such information confidential.  Upon the
                 termination of this Agreement, each party shall return or
                 destroy any Confidential Information received from the other
                 party upon request.

         (b)     Confidential Information does not include matters:

                 (i)      which are or become generally known to the public;

                 (ii)     independently developed by the recipient (provided
                          that the recipient has not used the Confidential
                          Information of the disclosing party);

                 (iii)    independently developed by a third party without
                          breach of





                                      11
<PAGE>   12
                          a confidentiality obligation to the disclosing party;
                          or

                 (iv)     required to be disclosed pursuant to order of court
                          or other governmental authority so long as the party
                          being required to make the disclosure gives prompt
                          notice thereof to the other party prior to such
                          disclosure (if possible).

         (c)     Each party acknowledges that a breach or threatened breach of
                 its obligations hereunder may cause irreparable damage to the
                 other party not adequately compensated by monetary damages.
                 Therefore, each party agrees that the non-breaching party
                 shall have the right to obtain, without the necessity of bond,
                 equitable remedies including without limitation specific
                 performance and injunctive relief, upon application.

         (d)     SigmaTron's Confidential Information may constitute material
                 non-public information which may be important to an investor
                 in making a decision to purchase or sell securities in
                 SigmaTron.  Until such time as Confidential Information is
                 made public, NSI agrees not to utilize such information in
                 purchasing or selling securities of SigmaTron and to use
                 reasonable efforts not to disclose any portion of such
                 information to a third party who might trade on the
                 Confidential Information or disclose it to others.

12.      INSURANCE:

         Each party agrees that at all times during the Term of this Agreement
         it shall carry property damage and general liability insurance
         (including without limitation product liability and business
         liability) coverage in an amount no less than $5,000,000 per
         occurrence and $5,000,000 overall.  Each party shall name the other
         party as additional insured under such policy and shall deliver to the
         other party a Certificate of Insurance as proof of such coverage
         status within ten days of the effective date of this Agreement and
         within ten days of the renewal date of any such insurance coverage.
         Each policy will also provide that no change or cancellation will be
         effective without 30 days' written notice to such additional insured.

13.      DEFAULT AND REMEDIES; TERMINATION:

         (a)     Either party may declare the other party in default:

                 (i)      if the defaulting party defaults in any payment to
                          the non-defaulting party and such failure continues
                          unremedied for a period of twenty (20) days after the
                          date of receipt by the defaulting party of written
                          notice specifying the default in reasonable detail;
                          or

                 (ii)     if the defaulting party defaults in its performance
                          of any other material term or condition of this
                          Agreement, or of any MPS issued pursuant to this
                          Agreement, and such default continues unremedied for
                          a period of thirty (30) days after the date of
                          receipt by the defaulting party of written notice
                          specifying the default in reasonable detail; or

                 (iii)    if the defaulting party files a petition in
                          bankruptcy, has a petition in bankruptcy filed
                          against it and such petition is not dismissed within
                          90 days, makes an assignment for the benefit of
                          creditors, suffers foreclosure of all or
                          substantially all of its assets or seeks the
                          appointment of a receiver for all or substantially
                          all of its assets.

         (b)     In the event of a default hereunder, the non-defaulting party
                 may, by thirty (30) days prior written notice to the
                 defaulting party, terminate this Agreement and all or any of
                 the privileges, permissions and rights granted to the
                 defaulting party hereunder or in connection herewith in whole
                 or in part.  The effective date of termination will be the
                 date therefor stated in any termination notice given
                 hereunder, which date will not be before the expiration of any
                 applicable cure period provided for herein.  Any such
                 termination will not effect the liability of either party for
                 any breach arising prior to such termination.

         (c)     Upon expiration of the Term or in the event of an unremedied
                 event of default by NSI (and the expiration of any cure
                 periods), SigmaTron may exercise any one or more of the
                 following remedies, in addition to any other remedies
                 available to it hereunder:

                 (i)      all inventory, components and materials (including
                          the Safety Stock), either in stock, on order and not
                          cancelable by SigmaTron without penalty, or not
                          useable by SigmaTron in the ordinary course of its
                          business, may be

                 (ii)     treated by SigmaTron as Obsolete Inventory 
                          under Section 6;

                          SigmaTron may terminate its obligations to
                          manufacture and assemble CO Detectors
                          exclusively for NSI;

                 (iii)    SigmaTron may sell to third parties any inventory,

                 by a merger, consolidation, reorganization, or a sale of
                 capital stock of SigmaTron, SigmaTron shall give notice to NSI
                 of such pending event.  Upon occurrence of such pending event,

                          right of any third party to the extent that such
                          infringement is based on SigmaTron's production for
                          NSI of CO Detectors in accordance with specifications
                          provided by NSI to SigmaTron under this Agreement.

                 to minimize the effect of any failure to perform or to
                 minimize the period of any delay.

                                  provide Contract Manufacturing Services.

                 Notwithstanding the foregoing, SigmaTron shall be immediately
                 released from its obligations under this subsection (i) if
                 SigmaTron terminates this Agreement as a direct result of an

                 (ii)     Each of SigmaTron and NSI agrees, for itself and its

                          a period of two years following any expiration or

                          each of the foregoing restrictions are reasonable.
                          In light of the fact that damages for a breach of any
                          such restrictions might be difficult to ascertain,

                          be entitled to injunctive relief in the event of an

                          remedies at law may be available to the non-breaching

                 incidental, or consequential damages.

         (n)     Right of Set-Off:  Each party is entitled to set off against
                 amounts it may owe to the other party amounts owed to it by
                 the other party in connection with this Agreement or any other
                 agreement between them.

agents, employees, representatives, or visitors, the Lessee shall continue to
pay the rent as if it were using said Building, and the Lessor will rebuild the
Leased Building within a commercially reasonable time after having received the
applicable insurance proceeds, including any deductible amount from those

or destroyed by any of the aforesaid causes or damaged or destroyed to an
extent rendering the same substantially unusable in Lessor's and Lessee's
judgment, then this Lease shall forthwith cease and terminate, in which event,

advance shall be refunded to Lessee within ten (10) days of said termination.

8.05 If the Leased Premises are destroyed or damaged more than Fifty percent
(50%) within One Hundred Eighty (180) days from the expiration of the initial
Lease term or extended term, Lessor is not required to rebuild or repair the

term of the Lease as provided under this Lease Agreement through the next
option period and Lessee is not in violation of any provisions contained in
this Lease Agreement including Lessee being current with all Lease payments.
If the extended term falls under these circumstances described in this section,

to cover repairs and the rebuilding of the damaged property.

or Lessee shall not preclude pursuit of any of the other remedies provided in
this Lease or at law or inequity.  Pursuit of any remedies provided in this
Lease or by law by either party shall not constitute a forfeiture or waiver of
any of the damages accruing to either party by reason of violation of any of
the terms, provisions, and covenants contained in this Lease, nor shall pursuit
of any remedies provided in this Lease by Lessor constitute a waiver, or
forfeiture or waiver of any rent due to Lessor under this Lease.

Leased Premises, Lessor has the right to waive the applicability of this
section so that this Lease will not be subject and subordinate to any such Deed
of Trust or mortgage.  Notwithstanding such subordination, Lessee's right to

in default and so long as Lessee shall pay the rent and observe and perform all
of the provisions of this Lease, unless this Lease is otherwise terminated
pursuant to its term.
