STATEMENT OF FAIR PRESENTATION

The financial information included herein is unaudited. In addition, the
financial information does not include all disclosures required under generally
accepted accounting principles because certain note information included in the
Company's annual report to shareholders has been omitted and such information
should be read in conjunction with the prior year's annual report. However, the
financial information reflects all adjustments (consisting solely of normal
recurring adjustments) which are, in the opinion of management, necessary to a
fair statement of the results for the interim periods. The Company considers
the disclosures adequate to make the information presented not misleading.

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


RESULTS OF OPERATIONS

Sales for the first six months of fiscal 1997 totaled $40.2 million compared
with sales of $46.2 million for the same period last year. Sales for the second
quarter of fiscal 1997 totaled $20.1 million, compared with $23.7 million for
the comparable period last year. New orders received for the first half of
fiscal 1997 were $35.8 million compared with $52.5 million for the same period
last year. New orders received in the second quarter totaled $20.5 million,
compared with $26.2 million for the same period last year. The decrease in
sales and orders for the quarter was due to the slower than expected receipt of
new orders for ceramic products and millimeter wave digital radio components.
Year-to-date sales and orders were impacted by the above as well as a softening
in the wireless telecommunications industry, the delayed rollout of the
Personal Communication System (PCS) and by the decision to exit certain
non-strategic activities.  

Gross profit for the first half of fiscal 1997 totaled $6.6 million compared
with $15.3 million for the comparable period last year. Gross profit for the
second quarter was $2.8 million compared with $7.9 million for the same period
last year. Lower margins are the result of lower sales volumes, rising costs
due to manufacturing capacity added during fiscal 1996, reserves for excess
inventory and a loss on a filter order. The inventory write-down of $1.5
million resulted from shifts in demand away from certain ceramic products at
Trans-Tech, Inc., the Company's subsidiary. A loss on a filter order of $500
thousand occurred when a customer redesigned the end product, requiring the
Company to scrap certain finished parts and materials and to issue credits for
returned product that was no longer required by the customer. In anticipation
of the demand for wireless communication products increasing over the second
half of fiscal 1997, the Company has decided to maintain or increase its
current levels of manufacturing capacity for MMICs, discrete semiconductors and
ceramic products in its U.S. facilities. In particular, the Company is
expanding its GaAs MMIC capacity to handle four inch wafers and is in the
process of adding a third shift to the GaAs fab.

Research and development expenses increased 27% for the first six months of
fiscal 1997 to $5.0 million, or 12% of sales, as compared with $3.9 million or
9% of sales for the same period last year. For the second quarter ended
September 29, 1996 research and development increased 16% to $2.5 million, or
12% of sales as compared to $2.1 million or 9% of sales. The increase in
research and development reflects the continued investment by the Company in the
GaAs MMIC and ceramic product lines.

Selling and administrative expenses increased 13% to $9.8 million or 25% of
sales for the first half of fiscal 1997, as compared with the same period last
year of $8.7 million or 19% of sales. For the second quarter ended September
29, 1996, selling and administrative expenses increased 3% to $4.5 million, or
22% of sales, as compared to $4.3 million or 18% of sales. The year-to-date
increase in selling and administrative expenses is primarily the result of
recognizing severance costs related to various corporate executives. The
increase in selling and administrative expenses for the second quarter reflects
an increase in sales and marketing activities directed toward expanded customer
service and market penetration.

Interest expense for the first six months and quarter ended September 29,
1996 decreased $194 thousand and $102 thousand, respectively, over the
comparable periods last year.  Interest income for the first six months and
quarter ended September 29,1996 increased $246 thousand and $89 thousand,
respectively, over the same periods last year. Funds received from the
secondary stock offering that was completed during the third quarter of fiscal
1996, were used to reduce debt and increase short-term investments thereby
resulting in decreased interest expense and increased interest income.   

                                       7

ALPHA INDUSTRIES, INC. AND SUBSIDIARIES

The Company reversed the income tax benefit of $604 thousand recorded in the
first quarter of fiscal 1997 because the Company no longer anticipates that
fiscal 1997 operations will be profitable.

For the first half of fiscal 1997, the Company reported a net loss of $8.2
million or $0.83 per share compared with a net income of $2.2 million or $0.27
per share for the comparable period last year. For the second quarter ended,
the Company reported a net loss of $4.7 million or $0.48 per share, compared
with net income of $1.1 million or $0.13 per share for the comparable period
last year. 

The Company announced on November 4, 1996 that it intends to divest its
European ceramics manufacturing operation, Trans Tech Europe, and its digital
radio subsystem product line. The Trans Tech Europe manufacturing operation has
provided ceramic manufacturing capacity at a higher cost than our U.S.
operation, which, coupled with improved efficiencies in Maryland, have made the
European operation unnecessary. Similarly, the divestiture of the digital radio
subsystem product line will remove the disproportionate risk and cost
associated with the manufacture of these highly complex and low-volume,
low-margin subsystems, which have led to some past unpredictability in the
Company's operating results. The Company expects to take any associated charges
related to these divestitures in the third quarter of fiscal 1997. The Company
is working to achieve favorable terms for the divestitures, but these charges
are not expected to exceed $2.6 million or $0.26 per share for the least
favorable outcome. 

FINANCIAL CONDITION

At September 29, 1996, working capital totaled $26.2 million and included
$10.2 million in cash, cash equivalents, and short-term investments, compared
with $32.6 million of working capital at the end of fiscal 1996. Cash decreased
$4.2 million during the first half of fiscal 1997 as a result of an $8.2
million loss, further investments in inventories and capital expenditures, as
well as, decreasing accounts payable. Capital expenditures were primarily for
continued automation of the semiconductor wafer fab operations and the MMIC and
discrete semiconductor assembly and test areas, as well as, for the improved
manufacturing capabilities of the ceramic manufacturing facilities. The Company
remains committed to adding the required capacity needed to service the
wireless markets as demand begins to return and therefore is expanding its GaAs
Fab to handle four inch wafer capability.  During the quarter, the Company
funded its capital expenditures by drawing down $4 million against its
equipment line of credit. The equipment line of credit was converted to a three
year term loan and at September 29, 1996, the total outstanding balance was
$4.8 million. 

With cash, cash equivalents and short-term investments of $10.2 million and
a $7.5 million line of credit available, the Company believes it has adequate
funds to support its current operating needs. The Company will continue to
evaluate other available financing such as low interest financing for the
capital expansion of its ceramic manufacturing business and any other sources
that may become available. 

Safe Harbor Statement - Except for the historical information contained
herein, this Form 10-Q contains forward-looking statements that are inherently
subject to risks and uncertainties. The Company's results could differ
materially based on various factors, including without limitation: cancellation
or deferral of customer orders, difficulties in the timely development and
market acceptance of new products, market developments that vary from the
current public expectations concerning the growth of wireless communications
(including PCS), difficulty in divesting the above-mentioned business
operations (including the possibility that the Company may be unable to
structure acceptable transactions), difficulties in manufacturing new or
existing products in sufficient quantity or quality, increased competitive
pressures, or changes in economic conditions. Further information on factors
that could affect the Company's financial results is included in the Company's
periodic reports filed with the S.E.C., including the most recent Form 10-K and
subsequent Form 10-Qs.

ITEM 1  LEGAL PROCEEDINGS

The Company does not have any material pending legal proceedings other than
routine litigation incidental to its business.

The Company has been notified by federal and state environmental agencies of
its potential liability with respect to the following two sites: the Spectron,
Inc. Superfund site in Elkton, Maryland; and the Seaboard Chemical Corporation
site in Jamestown, North Carolina. In each case several hundred other companies
have also been notified about their potential liability regarding these sites.
The Company continues to deny that it has any responsibility with respect to
these sites other than as a de minimis party. Management is of the opinion that
the outcome of the aforementioned environmental matters will not have a
material effect on the Company's operations or financial position.

3.   To use and occupy the leased premises solely for the following purposes

     Manufacture of ceramic components.
     ----------------------------------

Tenant shall have, as appurtenant to the Premises, rights to use in common,
subject to reasonable rules of general applicability to all tenants of the
Building from time to time made by Landlord and applied without

discrimination of which Tenant is given notice: common walkways and driveways,
and common parking areas serving the Building.  The Landlord shall diligently
pursue the construction of the building shell and use its best efforts to
complete such shell and Landlord supplied tenant improvements by July 31, 1996.
Landlord will cooperate with Tenant to allow Tenant early access to Premises for
its own improvements provided such early access does not delay Landlord work or
result in additional costs.

     UTILITIES

     4.   Tenant shall apply for and pay all costs of electricity, gas,
telephone and other utilities used or consumed on the premises, together with
all taxes, levies or other charges on such utilities.  Tenant agrees to pay as
additional rent Tenant's prorata share of the water and sewer service charges,
or when applicable, the cost of maintaining and operating the well water and/or
septic system chargeable to the total building in which the premises are
located, based upon the number of tenants occupying the same.  However, if in
Landlord's sole judgment, the water and sewer charges for the premises are
substantially higher than normal due to Tenant's water usage, then Tenant agrees
that it will, upon written notice from Landlord, install a water meter at
Tenant's expense and thereafter pay all water charges for the premises based on
such meter readings.

     MUNICIPAL REGULATING

     5.   Landlord and Tenant agree to observe, comply with and execute at its
expense, all laws, orders, rules, requirements, and regulations of the United
States, State, City or County of the said State, in which the leased premises
are located, and of any and all governmental authorities or agencies and of any
board of the fire underwriters or other similar organization, respecting the
premises hereby leased and the manner in which said premises are or should be
used by the Tenant.

     ASSIGNMENT AND SUBLET

     6.   Except for an assignment or sublease to the subsidiary, affiliate,
parent or successor by merger or consolidation of the within Tenant, not to
assign this lease, in whole or in part, or sublet the leased premises, or any
part or portion thereof, without the prior written consent of the Landlord.  If
such assignment or subletting is permitted, Tenant shall not be relieved from
any liability whatsoever under this lease.  The Landlord shall be entitled to
any additional considerations over and above those stated in this lease, which
are obtained in or for the sublease and/or assignment.  No option rights can be
assigned or transferred by the Tenant to an assignee or subtenant without the
prior written consent of the Landlord.

     INSURANCE

     7.   That the Tenant will not do anything in or about said premises that
will contravene or affect any policy of insurance against loss by fire or other
hazards, including, but not limited to, public liability now existing or which
the Landlord may hereafter place thereon, or that will prevent Landlord from
procuring such policies in companies acceptable to Landlord.  Tenant will
cooperate consistent with the conduct of Tenant's business to obtain the
greatest possible reduction in the insurance rates on the premises hereby
leased, or for the building of which the premises hereby leased are a part.  The
Tenant further agrees to pay, as part of and in addition to the next due monthly
rental:

<PAGE>
 
     a.   its prorata share (approximately 33% - exact percentage to be set
forth in amendment) of the premium of any insurance on the premises hereby
leased or for the building of which the premises hereby leased are apart;

     b.   any increase in premium on the amount of such insurance that may be
carried by Landlord on all or any part of the premises or the property resulting
from the activities carried on by Tenant in or at the Premises, regardless of
whether Landlord has consented to the same.

     ALTERATIONS

     8.   (a)  That the Tenant will not make any alterations costing more than
$50,000 in any one instance (in addition to original improvements) to said
premises without the prior written consent of the Landlord.  If the Tenant shall
desire to make any such alterations, plans for the same shall first be submitted
to and approved by the Landlord, such approval not to be unreasonably withheld
and the same shall be done by the Tenant at its own expense, and the Tenant
agrees that all such work shall be done in a good and workmanlike manner, that
the structural integrity of the building shall not be impaired, and that no
liens shall attach to the premises by reason thereof.  In all cases, regardless
of cost, Tenant will notify Landlord fourteen (14) days prior to commencement of
improvements and provide as built drawings.

          (b)  The Tenant agrees to obtain at the Tenant's expense all permits
pertaining to the alterations.  The Tenant also agrees to obtain, prior to
beginning to make such alterations, and to keep in full force and effect at all
times while such alterations are being made, all at the Tenant's sole cost and
expense, such policies of insurance pertaining to such alterations and/or to the
making thereof as the Landlord reasonably may request or require the Tenant to
obtain, including, but not limited to, public liability and property damage
insurance, and to furnish the Landlord evidence satisfactory to the Landlord of
the existence of such insurance prior to the Tenant's beginning to make such
alterations.

          (c)  Any such alterations shall become the property of the Landlord as
soon as they are affixed to the premises and all rights, title and interest
therein of the Tenant shall immediately cease, unless otherwise agreed to in
writing.  The Landlord shall have the sole right to collect any insurance
proceeds from any policy carried by Landlord for any damage of any kind to any
of the improvements placed upon the said premises by the Tenant.  If the making
of any such alterations, or the obtaining of permits or franchise therefore
shall directly or indirectly result in a franchise, minor privilege or any other
or any tax or increase in tax, assessment or increase in assessment, such tax or
assessment shall be paid, immediately upon  its levy and subsequent levy, by the
Tenant.

          (d)  Unless the Landlord shall elect that all or part of any
alterations installed by Tenant shall remain, the premises shall be restored to
their original condition by the Tenant, at its own expense, before the
expiration of its tenancy. Such restoration shall not be required except to the
extent reasonably necessary to allow the premises to be used as shell warehouse
space.

     MAINTENANCE

     9.   The Tenant will, during the term of this lease, keep said demised
premises and appurtenances (including interior and exterior windows, interior
and exterior doors, interior plumbing, all heating and air conditioning, and
interior electrical works thereof) in good order and condition and will make all
necessary repairs including painting thereto at its own expense.  Tenant will be
responsible for all exterminating services, except termites, required in said
demised premise.  The Landlord does, however, give a 90 day warranty on all of
the above mentioned items.  If the Tenant does not commence necessary repairs 30
days after receiving written notice from the Landlord of the need to make a
repair, the Landlord will proceed to make said repair and the cost of said
repair will become part of and in addition to the next due monthly rental.  The
Landlord will make all necessary structural repairs to the exterior masonry
walls, structural columns and roof of the demised premises, after being notified
of the need for such repairs.  The Tenant will, at the expiration of the term or
at the sooner termination thereof by forfeiture or otherwise, deliver up the

<PAGE>
 
demised premises in the same good order and condition as they were at the
beginning of the tenancy, reasonable wear and tear excepted.  Tenant agrees to
furnish to Landlord at Tenant's expense within 30 days of occupancy a copy of an
executed maintenance contract on all heating & air conditioning equipment with a
reputable company and said contract  will be kept in effect during the term of
this Lease.



     COMMON AREA EXPENSES

     10.  For each full or partial calendar year during the Lease Term, Tenant
shall pay to Landlord as Additional Rent "Tenant's Proportionate Share" of the
Common Area Expenses (Tenant's proportionate share will be approximately 33% -
exact percentage to be set forth in amendment).  For the purposes of this
section, Common Area Expenses shall be defined as one hundred percent (100%) of
the total cost and expense incurred by or on behalf of Landlord in each calendar
year in operating, maintaining, and repairing (which includes replacements,
additions, and alterations) of Common Areas of the building.  These include,
without limitation, a) the cost of maintaining, repairing, or replacing all
service pipes, electric gas and waterlines and sewer mains leading to and from
the Premises; b) all costs incurred in painting, resurfacing, and landscaping;
c) all costs for repairs and improvements, line painting and striping, lighting,
removal of snow, grass cutting, cleaning of parking areas; d) all costs incurred
in maintaining, repairing and replacing the paving, parking areas, curbs,
gutters, sidewalks, and steps; and e) management fees equal to 4% of rent.

     Landlord shall also perform the following work at the Tenant's pro-rata
expense:

          Roof Maintenance & Repair
          Exterior Glass Maintenance & Repair
          Landscape Maintenance
          Snow Removal
          Exterior Lighting Maintenance & Repair
          Parking Lot Maintenance & Repair items
          Miscellaneous Maintenance & Repair items relative to the Building
          Landlord will pay on behalf of Tenant and bill Tenant its pro-rata
           share of:
               Real Estate Taxes
               Insurance
               Water & Sewer

     Landlord reserves the right to estimate those expenses each fiscal year and
invoice tenant on a monthly or quarterly basis for the fractional share due as a
prepayment towards common  area, maintenance costs, insurance and real estate
taxes.  After the end of each fiscal year, Landlord will tabulate the actual
cost of Common Area Maintenance, Real Estate Taxes and Insurance and bill Tenant
for the balance due or refund any overpayment.  Tenant may audit such costs
within 30 days of fiscal year end.  If such costs are more than 10% in error,
Landlord will pay the reasonable cost of such audit.  Landlord will provide 240
parking spaces for the initial 60,000 square foot occupancy and an additional
150 parking spaces should Tenant exercise its option to expand to an additional
40,000 square feet.

     TAXES

     11.  The premises covered by this lease form approximately 33% - (exact
percentage to be set forth in amendment) of the total premises owned by the
Landlord at this location.  The Tenant shall pay, as additional rent, the
Tenant's percentage of the Real Estate taxes as the same may be abated that may
be levied or assessed by lawful taxing authorities against the land, buildings
and improvements on the property.  If this lease shall be in effect for less
than a full fiscal year, the Tenant shall pay a pro-rata share of the increased
taxes based upon the number of months that this lease is in effect.  Said taxes
shall include, but not by way of limitation, all paving taxes, and any and all
benefits or assessments which may be levied on 

<PAGE>
 
the premises hereby leased but shall not include the United States Income Tax,
or any State or other income tax upon the income or rent payable hereunder.

     DEFAULT

     12.  If the Tenant shall fail to pay said rental or any other sum required
by the terms, agreements, or addenda of this lease when the same shall be due,
and within five (5) days after written notice (Landlord shall only be obligated
to provide such written notice two times in any year),  the Landlord shall have
along with any and all other legal remedies the immediate right to make distress
therefore, and upon such distress, in the Landlord's discretion, this tenancy
shall terminate.  In case the Tenant shall fail to comply with any of the other
provisions, covenants, or conditions of this lease, on its part to be kept and
performed, and such default shall continue for a period of thirty days after
written notice thereof shall have been given to the Tenant by the Landlord,
and/or if the Tenant shall fail to pay said rental or any other sum required by
the terms of this lease to be paid by the Tenant when due and within five (5)
days after written notice (Landlord shall only be obligated to provide such
written notice two times in any year), then, upon the happening of any such
event, and in addition to any and all other remedies that may thereby accrue to
the Landlord, the Landlord may elect to either:

     1.   Landlord's Election to Retake possession without Termination of Lease.
          --------------------------------------------------------------------- 
Landlord may retake possession of the leased premises and shall have the right,
but not the obligation, without being deemed to have accepted a surrender
thereof, and without terminating this Lease, to relet the same for the remainder
of the lease term upon terms and conditions satisfactory to Landlord; and if the
rent received from such reletting does not at least equal the rent payable by
Tenant hereunder, Tenant shall pay and satisfy on a monthly basis and without
acceleration  the deficiency between the amount of rent so provided in this
Lease and the rent received through reletting the leased premises; and, in
addition, Tenant shall pay reasonable expenses in connection with any such
reletting, including, but not limited to, leasing commissions paid to any real
estate broker or agent, and reasonable attorney's fees incurred.

     2.   Landlord's Election to Terminate Lease.  Landlord may terminate the
          ---------------------------------------                            
Lease and forthwith repossess the leased premises and be entitled to recover as
damages a sum of money equal to the net present value of the following amounts:

     a.   any unpaid rent or any other outstanding monetary obligation of Tenant
to Landlord under the Lease;

     b.   the balance of the rent for the remainder of the lease term less the
reasonable rental value of the leased premises;

     c.   damages for the wrongful withholding of the leased premises by Tenant;

     d.   all legal expenses, including reasonable attorney's fees, expert and
witness fees, court costs and other costs incurred in exercising its rights
under the Lease;

     e.   all costs incurred in recovering the leased premises, restoring the
leased premises to good order and condition, and all commissions incurred by
Landlord in reletting the leased premises.

     DAMAGE

     13.  In the case of the total destruction of said leased premises by fire,
other casualties, the elements or other cause, or of such damage thereto as
shall render the same totally unfit for occupancy by the Tenant for more than 60
days, this lease, shall terminate and be at an end.  If the leased premises are
rendered partly untenantable by any cause mentioned in the preceding sentence,
the Landlord shall, at its own expense, restore said leased premises with all
reasonable diligence, and the rent shall be abated

<PAGE>
 
proportionately for the period of said partial untenantability and until the
leased premises shall have been fully restored by the Landlord.

     BANKRUPTCY

     14.  In the event of the appointment of a receiver or trustee for the
Tenant by any court, Federal and State, in any legal proceedings under any
provisions of the Bankruptcy Act, if the appointment of such receiver or such
trustee is not vacated within 60 days, or if said Tenant be adjudicated bankrupt
or insolvent, or shall make an assignment for the benefit of its creditors, then
and in any of said events, the Landlord may, at its option, terminate this
tenancy by ten days written notice, and re-enter upon said premises.


     POSSESSION

     15.  The Landlord covenants and agrees that possession of said premises
shall be given to the Tenant as soon as said premises are ready for occupancy by
the said Tenant.  In case possession, in whole or in part, cannot be given to

abate the rent proportionately until possession is given to said Tenant, and the
Tenant agrees to accept such pro rata abatement as liquidated damages for the
failure to obtain possession.

portion of said premises for ninety (90) days prior to termination of this lease
and to place a "For Sale" sign thereon at any time.

     OUTSIDE

     17.  The Tenant further covenants and agrees not to put any items on the
sidewalk or parking lot in the front, rear, or sides of said building or block

properties, to determine market rate as herein defined.  Such third arbitrator
and the first two chosen shall hear the parties and their evidence and render
their decision within thirty (30) days following the conclusion of such hearing
and notify Landlord and Tenant thereof.  Landlord and Tenant shall share equally
the expense of the third arbitrator (if any).  If the dispute between the
parties as to a market rate has not been resolved before the commencement of

then Tenant shall pay Rent and Addition Rent under the Lease based upon the then
current rate until either the agreement of the parties as to the market rate, or
the decision of the arbitrators, as the case may be, at which time Tenant shall
pay any underpayment of Rent and Additional Rent to Landlord, or Landlord shall
refund any overpayment of Fixed Rent and Additional Rent to Tenant.

     a.   If the option to extend the term of this Lease is not timely
exercised, the unexercised option to extend shall automatically become null and
void.
