Item 1.  Description of Business

General

         Digital Power  ("Digital  Power" or the "Company")  designs,  develops,
manufactures,  and sells 50 watt to 750 watt switching  power supplies and DC/DC
converters  to original  equipment  manufacturers  (OEMs) of computers and other
electronic  equipment.  Power  supplies are critical  components  of  electronic
equipment that supply, convert,  distribute,  and regulate electrical power. The
various subsystems within electronic equipment require a steady supply of direct
current (DC)  electrical  power,  usually at different  voltage  levels from the
other subsystems within the equipment.  In addition,  the electronic  components
and  subsystems  require  protection  from  the  harmful  surges  and  drops  in
electrical  power that commonly occur over power lines.  Power supplies  satisfy
these requirements by converting alternating current (AC) electricity into DC by
dividing a single input voltage into distinct and isolated output voltages,  and
by regulating  and  maintaining  such output  voltages  within a narrow range of
values.

        Products  which  convert  AC from a  primary  power  source  into DC are
generally  referred to as "power supplies."  Products which convert one level of
DC voltage into a higher or lower level of DC voltage are generally  referred to
as  "DC/DC  converters."  "Switching"  power  supplies  are  distinguished  from
"linear" power supplies by the manner and efficiency with which the power supply
"steps down" voltage  levels.  A linear power supply  converts an unregulated DC
voltage to a lower regulated  voltage by "throwing away" the difference  between
the two voltages as heat.  Consequently,  the linear power supply is  inherently
inefficient-typically only 45% efficient for a 5V output regulator. By contrast,
a switching power supply converts an unregulated DC voltage to a lower regulated
voltage by storing the difference in a magnetic  field.  When the magnetic field
grows to a  pre-determined  level,  the  unregulated  DC is switched off and the
output power is provided by the energy  stored in the magnetic  field.  When the
field is  sufficiently  depleted,  the  unregulated  DC is  switched on again to
deliver  power to the  output  while the excess  voltage is again  stored in the
magnetic   field.   As  a   result,   the   switching   power   supply  is  more
efficient-typically 75% efficient for a 5V output regulator.

<PAGE>3

        One of the great advantages of switching power supplies,  in addition to
their high efficiency,  is their high power density,  or power-to-volume  ratio.
This  density  is  the  result  of the  reduction  in the  size  of the  various
components.  Because the Company's  switching  power supply products have a high
power  density,  they are  generally  smaller  than  those of  competitors.  For
example, to the Company's knowledge its US100 series of power supplies, on a 3"x
5" printed  circuit  board,  is the smallest 100 watt  off-line (AC input) power
supply available in the industry.

        Another  advantage  of the  Company's  power  supply  products  is their
extreme flexibility of design. The Company has purposely designed its base model
power supply products so that they can be quickly and inexpensively modified and
adapted  to the  specific  power  supply  needs of any OEM.  This  "flexibility"
approach has allowed the Company to provide  samples of modified  power supplies
to OEM  customers in only a few days after  initial  consultation,  an important
capability  given the emphasis  placed by OEMs on "time to market." In addition,
this "flexibility" approach results in very low non-recurring  engineering (NRE)
expenses.  Because of its reduced NRE expenses,  the Company does not charge its
OEM  customers  for NRE  related to  tailoring  a power  supply to a  customer's
specific  requirements.  This gives the  Company a distinct  advantage  over its
competitors,  many of whom do  charge  their  customers  for NRE  expenses.  The
Company's  marketing  strategy  is to  exploit  this  combination  of high power
density, design flexibility, and short time-to-market to win an increasing share
of the growing power supply market.

        In addition to the line of proprietary products offered, and in response
to requests from OEMs, the Company also provides  "value-added  services"  along
with its  products.  The term  "value-added  services"  refers to the  Company's
incorporation of an OEM's selected electronic components,  enclosures, and cable
assemblies  with  the  Company's  power  supply  products  to  produce  a  power
subassembly  that is compatible with the OEM's own equipment and is specifically
tailored to meet the OEM's needs. The Company purchases the parts and components
that the OEM itself would  otherwise  attach to or integrate  with the Company's
power  supply,  and the  Company  provides  the OEM with  that  integration  and
installation  service,  thus saving the OEM time and money. The Company believes
that this  value-added  service is  well-suited to those OEMs who wish to reduce
their vendor base and minimize  their  investment  in fixed costs since the OEMs
are not required to manufacture  their own power  subassemblies and thus are not
required  to  purchase  individual  parts from many  vendors  or build  assembly
facilities.

        Digital Power Corporation is a California  corporation originally formed
in 1969  through a  predecessor.  Unless the context  indicates  otherwise,  any
reference to "Digital Power" or the "Company" herein includes its majority-owned
Mexican  subsidiary,   Poder  Digital  S.A.  de  C.V.  and  its  United  Kingdom
subsidiary,  Digital  Power  Limited,  dba Gresham Power  Electronics.  Further,
unless  otherwise  indicated,  reference to dollars in this Annual  Report shall
mean United States dollars.

1998 Activity

        At the end of calendar  year 1997,  the Company was informed by its then
largest customer that it would cease making purchases of power supplies from the
Company.  That customer accounted for approximately 24.4% of the Company's total
sales during 1997.  Further,  during calendar year 1998, there was a softness in
the overall  market for power  supplies.  As a result  during 1998,  the Company
experienced a substantial  decrease in revenues of approximately $7 million from
its United States operations.  The decrease in revenues,  however, was offset by
revenues  acquired  through the  acquisition  of certain assets of Gresham Power
Electronics  in January 1998 discussed below. The Company is conducting business

<PAGE>4

in Europe through its wholly-owned subsidiary Digital Power Limited, dba Gresham
Power  Electronics  ("Gresham  Power").  In  addition,  the  Company had certain
adverse  adjustments  to its cost of goods  sold due to  obsolescence  and price
erosion of the Company's inventory.  Finally, during 1998, the Company increased
its research and development expenditures to develop new products. Due to all of
these factors, the Company incurred a net loss of $570,588 during 1998.

Gresham Power

        Pursuant to an Asset Sale  Agreement (the  "Agreement"),  on January 22,
1998,  Digital  Power  acquired  the assets of Gresham  Power  Electronics  from
Gresham Lion Technology Limited,  an English  corporation  ("Gresham Lion"). The
consideration paid for the acquisition was $2.7 million, which amount is subject
to adjustment  depending upon the net asset value (accounts  receivables,  fixed
assets  and  inventory  less  liabilities)  ("NAV")  as  of  the  closing  date.
Specifically,  pursuant  to the  Agreement,  the  acquisition  amount  shall  be
increased  by $1.6284 for each United  Kingdom  pound that  Gresham  Power's NAV
exceeds  UK(pound)1,100,000  as of the  closing  date,  and shall be  reduced by
$1.6284   for  each   United   Kingdom   pound   that  the  NAV  is  less   than
UK(pound)1,100,000 as of the closing date. In addition to the foregoing,  if the
NAV as of March 31,  1998,  equals or exceeds  UK(pound)1,606,000,  Gresham Lion
shall be paid an additional $300,000 subject to a reduction of $1.6284 for every
United Kingdom pound NAV is less than UK(pound)1,606,000. Further, Digital Power
shall pay Gresham Lion an  additional  $1.15 for every United  Kingdom  pound of
earnings  before  interest  and taxes which  exceeds  UK(pound)250,000,  up to a
maximum additional payment of $300,000. As a result of primarily Gresham Power's
NAV as of the closing date,  and, to a lesser  extent,  Gresham Power  achieving
certain earnings,  Digital Power paid an additional $371,978 in the aggregate to
Gresham Lion.

        Headquartered   in   Salisbury,    England,   Gresham   Power   designs,
manufactures,  and distributes  switching power supplies,  uninterruptible power
supplies,  and frequency  converters for the  commercial  and military  markets.
Uninterruptible  power  supplies  (UPS) are devices that are inserted  between a
primary power source and the primary power input of the electronic  equipment to
be protected for the purpose of eliminating  the effects of transient  anomalies
or temporary outages. A UPS consists of an inverter that is powered by a battery
that is kept trickle-charged by rectified AC from an incoming power line. In the
event of a power interruption, the battery takes over without the loss of even a
fraction  of a cycle in the AC  output of the UPS.  The  battery  also  provides
protection against  transients.  A frequency converter is an electronic unit for
speed control of a phase induction motor. The frequency  converter  controls the
motor speed by  converting  the frequency and voltage of the power main's supply
from fixed to variable  values.  This is the most efficient means of varying the
fixed speed of an  induction  motor,  since other  methods  involve  great power
losses or great investments. The acquisition of Gresham Power will diversify the
Company's  product  line,  provide  greater  access to the  United  Kingdom  and
European markets, and strengthen Digital's engineering and technical resources.

The Market

        Since all  electronic  equipment  requires power  supplies,  the overall
market for power supplies is very large. The growth of the power supply industry
has paralleled that of the general electronics industry.  Since 1994, growth has
escalated  at  an  even  faster  pace,  fueled  by  the  demand  for  networking
communications  equipment and computing  equipment and its  peripherals.  Future
growth  is  expected  tocome  from  the  same  markets, as internet and intranet

<PAGE>5

networking and cellular and digital telephones continue to become popular around
the world.

        The electronic power supply market is typically split into "captive" and
"merchant"  market  segments.  The captive  segment of the market,  that portion
represented by OEMs who design and  manufacture  power supplies for use in their
own  products.  The remaining  power supply  market is served by merchant  power
supply  manufacturers,  such as Digital Power, that design and manufacture power
supplies for sale to OEMs.

        The Company  believes  that the merchant  market is the fastest  growing
segment of the power supply  market,  as OEMs continue to outsource  their power
supply requirements. The Company believes that this increase is due, in part, to
the fact that power supplies are becoming an increasingly  complex  component in
the eyes of OEMs, with  constantly  changing  requirements  such as power factor
correction  (PFC)  and  filtering  specifications  to  minimize  electromagnetic
interference (EMI).

        The  power  supply  market  can also be  divided  between  "custom"  and
"standard"  power supplies.  Custom power supplies are those that are customized
in design and manufactured with a specific application in mind, whereas standard
power supplies are sold  off-the-shelf to customers whose  electronic  equipment
can operate from  standard  output  voltages  such as 5, 12, or 24 volts.  Power
supplies in the captive market that are designed and  manufactured by an OEM for
use in its own  equipment are an example of a custom  design,  as the product is
not intended for resale.  However,  custom power supplies are also common in the
merchant  market,  as certain OEMs contract with power supply  manufacturers  to
design a product that meets the form,  fit, and  function  requirements  of that
OEM's specific  application.  A subset of the standard segment of the market has
evolved, commonly known as "modified standard" segment,  comprising power supply
products that have the performance  characteristics  of a standard power supply,
but require certain, usually minor, modifications. These modifications typically
involve an adjustment  to one of the standard  output  voltages,  such as from 5
volts to 7 volts, or from 15 volts to 18.5 volts.

        The power supply industry is highly fragmented.  There are approximately
300 domestic merchant power supply  competitors in the United States,  with over
200 that generate less than $5 million in revenues.  No one  manufacturer  holds
more than five percent of the total market.  The merchant market segment is also
highly  fragmented  according  to the power  level,  technology,  packaging,  or
application of a merchant's particular power supply. Most merchant manufacturers
concentrate on niche markets, whether power ranges or industry segments.

        With no industry  standards for power supplies,  it is very difficult to
design out an existing power supply  component  which  prevents large  companies
from quickly gaining market share. The key to being a profitable manufacturer is
to have  long-term  expertise  in power  electronics  and to be able to  provide
products needed by customers. The Company has targeted and serves the industrial
and  office  automation,  industrial  and  portable  computing,  and  networking
applications  niches of the merchant market. The Company believes that its focus
on  high-efficiency,  high-density,  design-flexible  power  supplies is ideally
suited to the rapid growth opportunities existing in this market segment.

        Geographically,  Digital Power primarily serves the North American power
electronics  market with AC/DC power supplies and DC/DC converters  ranging from
50 watts to 750 watts of total output power.

<PAGE>6

Gresham Power serves the United Kingdom  marketplace  with AC/DC power supplies,
uninterruptible  power supplies,  and frequency  inverters.  Both commercial and
government (Ministry of Defense) markets are served by Gresham Power.

Customers

        Digital Power's  products are sold  domestically and in Canada through a
network of 14 manufacturers' representatives. Digital Power also has 23 stocking
distributors  in the United  States and  Europe.  In  addition,  the Company has
formed strategic  relationships with three of its customers to private label its
products.  Digital  Power's  customers can generally be grouped into three broad
industries,  consisting  of  the  computer,  telecommunication,  and  instrument
industries.  The  Company  has a  current  base of over  150  active  customers,
including companies such as Ascend  Communications,  Telex,  Storage Dimensions,
Motorola,  Stanford  Telecommunications,  Extreme Network,  Ericsson and British
Telecom.

Strategy

        Digital  Power's  strategy  is to be the  supplier  of  choice  to  OEMs
requiring a  high-quality  power solution where size,  rapid  modification,  and
time-to-market are critical to business success.  Target market segments include
telecommunications,  networking,  switching,  mass storage,  and  industrial and
office automation products.  While many of these segments would be characterized
as  computer-related,  the Company does not participate in the personal computer
(PC) power  supply  market  because of the low  margins  arising out of the high
volume and extremely competitive nature of that market.

        The  Company  intends  to  continue  its  sales  primarily  to  existing
customers while simultaneously  targeting sales primarily to new customers.  The
Company believes that its "flexibility" concept allows customers a unique choice
between its  products and  products  offered by other power supply  competitors.
OEMs have  typically  had to settle for a standard  power  supply  product  with
output  voltages  and  other  features   predetermined   by  the   manufacturer.
Alternatively,  if the OEM's  product  required a different  set of power supply
parameters,  the OEM was forced to design this modification  in-house,  or pay a
power supply  manufacturer  for a custom product.  Since  custom-designed  power
supplies are development-  intensive and require a great deal of time to design,
develop,  and manufacture,  only OEMs with significant  volume  requirements can
economically  justify the expense and delay  associated  with their  production.
Furthermore,  since virtually every power conversion product intended for use in
commercial  applications  requires certain  independent safety agency testing at
considerable  expense,  such  as by  Underwriters  Laboratories,  an  additional
barrier is  presented  to the smaller  OEM. By offering  the OEM  customer a new
choice with the Digital Power "flexibility"  series, the Company believes it has
an  advantage  over its  competitors.  The  Company's  "flexibility"  series  is
designed  around a  standardized  power  platform,  but allows the  customer  to
specify  output  voltages  tailored to its exact  requirements  within  specific
parameters.  Furthermore,  OEMs are seeking  power  supplies  with greater power
density. Digital Power's strategy in responding to this demand has been to offer
increasingly smaller power supply units or packages.

Product Strategy and Products

        Digital  Power has nine series of base designs  from which  thousands of
individual models can be produced. Each series has its own printed circuit board
(PCB) layout that is common to all models  within the series  regardless  of the
number  of  output  voltages  (typically  one  to  four)  or the  rating  of the

<PAGE>7

individual output voltages.  A broad range of output ratings,  from 3.3 volts to
48 volts, can be produced by simply changing the power transformer  construction
and a small number of output  components.  Designers of  electronic  systems can
determine  their  total power  requirements  only after they have  designed  the
system's  electronic  circuitry  and selected the  components  to be used in the
system.  Since the designer has a finite  amount of space for the system and may
be under competitive  pressure to further reduce its size, a burden is placed on
the power supply manufacturer to maximize the power density of the power supply.
A  typical  power  supply  consists  of a PCB,  electronic  components,  a power
transformer and other electromagnetic components, and a sheet metal chassis. The
larger   components   are   typically   installed   on  the  PCB  by   means  of
pin-through-hole  assembly where the  components  are inserted into  pre-drilled
holes and soldered to electrical  circuits on the PCB.  Other  components can be
attached  to the PCB by surface  mount  interconnection  technology  (SMT) which
allows  for a  reduction  in board  size  since  the holes  are  eliminated  and
components can be placed on both sides of the board.  The Company's US100 series
is an example of a product using this manufacturing technology.

        Digital  Power's  "flexibility"  concept applies to all of the Company's
US, UP/SP,  and DP product  series.  A common printed circuit board is shared by
each model in a particular  family,  resulting in a reduction in parts inventory
while allowing for rapid modifiability into thousands of output combinations.
The following is a description of the Company's products.

        The US50 series of power supplies consists of compact,  economical, high
efficiency,  open frame  switchers  that  deliver  up to 50 watts of  continuous
power,  or 60 watts of peak  power,  from one to four  outputs.  The  90-264 VAC
universal  input  allows them to be used  worldwide  without  jumper  selection.
Flexibility options include chassis and cover, power good signal, an isolated V4
output,  and UL544  (medical)  safety  approval.  All US50 series units are also
available in 12VDC,  24VDC,  or 48VDC inputs.  This optional DC input unit (DP50
series) maintains the same pin-out, size, and mounting as the US50 series.

        The US70  series of power  supplies  is  similar to the US50  series,  a
compact,  economical,  highly efficient, open frame switcher that delivers up to
65 watts with a 70 watt peak.  This unit is offered with one to four outputs,  a
universal  input rated from 90 to 264 VAC, and is only slightly  larger than the
US50 series.  The US70 series is  differentiated  from competitive  offerings by
virtue of its smaller  size,  providing  up to four  outputs  while  competitors
typically are limited to three outputs. Flexibility options include cover, power
good signal,  an isolated V4 output,  and UL544 (medical) safety  approval.  The
DP70 is the same as the US70 except the input is 48 volts DC. The  Company  also
offers 12 & 24VDC DC input on this series where the model series changes to DN &
DM. This type of product is ideal for low profile systems, with the power supply
measuring 3.2" x 5" x 1.5".

        The US100/DP100 is the industry's smallest 100 watt switcher.  Measuring
only 5" x 3.3" x 1.5", this series delivers up to 100 watts of continuous power,
or 120 watt peak power, from one to four outputs.  The 90-264VAC universal input
allows them to be used worldwide.  This product is ideal in  applications  where
OEMs have upgraded their systems,  requiring an additional 30-40 watts of output
power but being unable to  accommodate a larger unit. The US100 fits in the same
form factor and does not require any tooling or  mechanical  changes by the OEM.
Flexibility  options include a cover and adjustable post regulators on V3 and/or
V4 outputs.  Fully customized models are also available.  All US100 series units
are also available with 12VDC,  24VDC, or 48 VDC inputs.  This optional DC input
unit (DP100) maintains the same pin-out, size, and mounting as the US100 series.

<PAGE>8

        The UP300 series  consists of economical,  high  efficiency,  open frame
switchers  that  deliver  up to 300  watts of  continuous,  or 325 watts of peak
power,  from one to two outputs.  The 115/230VAC  auto-  selectable input allows
them to be  used  worldwide.  On-board  EMI  filtering  is a  standard  feature.
Flexibility  options  include a cover,  power  fail/power  good  signal,  and an
isolated 2nd output.  The UP300 is also available as the SP300 series,  which is
jumper  selectable  between  115 and  230VAC and  provides  the OEM an even more
economical  solution.  This product can be used in network  switching systems or
other  electronic  systems where a lot of single output current,  such as 5, 12,
24, or 48 volt current might be required.

        The US250 series  consists of economical,  high  efficiency,  open frame
switchers that deliver up to 250 watts of continuous power, or 300 watts of peak
power,  from one to four outputs.  The 115/230VAC  auto-selectable  input allows
them to be used worldwide.  Flexibility  options include cover, power fail/power
good signal,  enable/inhibit,  and an isolated V3 output. All US250 series units
are also available with 12VDC,  24VDC,  or 48VDC inputs.  This optional DC input
unit (DP250) maintains the same pin-out, size, and mounting as the US250 series.

        The US350  series is a  full-featured  unit that has active power factor
correction  and  was  designed  to  be   field-configurable   by  the  Company's
international  and domestic  sales  channels.  This feature  allows the stocking
distributor  to lower its inventory  costs but still maintain the required stock
to rapidly provide power supplies with the unique combination of output voltages
required by an OEM. This unit delivers 350 watts from one to four output modules
and  meets  the  total  harmonic  distortion  spec IEC  555.2.  The US350 has an
on-board EMI filter and operates from 90-264 VAC input.  This unit measures 9" x
5" x 2.5". It can operate without any minimum loads and has an optional internal
fan and power fail/power good signal.

        The newest product  developed by the Company is the UPF 150 series.  The
UPF 150 is an open- frame  switcher  that  delivers up to 150watts of continuous
power  from  one to four  outputs.  The UPF 150 is  endowed  with  power  factor
correction and a Class B EMI filter, making the series particularly  well-suited
for those customers selling into the international market place.

        The Company also produces two products  designated as the KD series in a
150 watt and 200 watt product.  These designs were licensed in 1987, and amended
in 1990,  under a  licensing  agreement  with KDK  Electronics.  They are  still
offered for sale but are  expected to  continue  to decline as a  percentage  of
Digital  Power's  revenues.  The licensing  agreement with KDK  Electronics,  as
amended, provides that KDK Electronics will be paid a royalty equal to 5% on the
first  $20  million  total  sales of the KD  series  products  with the  royalty
decreasing  on sales over that amount.  Further,  in the event total  historical
sales of KD products reach $20 million,  then KDK Electronics  will be granted a
stock  option to purchase  100,000  shares of Digital  Power's  common stock for
$3.50 per share with Digital Power paying the exercise price.

         In  connection  with  litigation  involving  KDK  Electronics  and  the
Company,  on September 3, 1998, the Company  entered into a Technology  Transfer
Agreement  with KDK  Electronics.  Under  the terms of the  Technology  Transfer
Agreement, the Company acquired from KDK Electronics the technology and right to
sell in the  future  products  that may be  derived  under  the  1987  licensing
agreement,  as  amended,  between  KDK  Electronics  and  the  Company.  For the
acquisition  of  the  technology  and  future  sales  rights  and  settlement of

<PAGE>9

litigation,  the Company  issued  35,000 shares of its common stock and will pay
$150,000 in $7,000  monthly  payments,  beginning in October 1998.  "See Item 3.
Legal Proceedings."

        Digital  Power  offers  its  customers   various  types  of  value-added
services,  which may include the  following  additions to its  standard  product
offerings:

        Electrical (power):  Paralleled power supplies for (N+1) redundancy, hot
swapability,  output OR'ing diodes, AC input receptacle with fuse,  external EMI
filter, on/off switch, cabling and connectors, and battery backup with charger.

        Electrical  (control and  monitoring):  AC power fail detect signal,  DC
output(s) OK signal,  inhibit,  output voltage  margining,  and digital  control
interface.

        Mechanical:  Custom  hot-plug  chassis  for  (N+1)  redundant operation,
locking handle, cover, and fan.

        These services incorporate one of the Company's base products along with
additional  enclosures,  cable  assemblies,  and other electronic  components to
arrive at a power subassembly.  This strategy matches with those OEMS wishing to
reduce  their  vendor  base,  as the turnkey  sub-assembly  allows  customers to
eliminate other vendors.

        Other than certain  fabricated  parts such as printed circuit boards and
sheet metal chassis which are readily available from many suppliers, the Company
uses no custom  components.  Typically,  two  suppliers  are qualified for every
component,  with the  exception  being  one  line  transformer  manufactured  by
Spitznagel.  This  transformer  is designed into one of the Company's  products,
which accounted for less than 10% of the Company's total sales in 1998.

Manufacturing Strategy

        Consistent with its product  flexibility  strategy,  the Company aims to
maintain a high degree of flexibility in its manufacturing processes in order to
respond  to  rapidly  changing  market  conditions.  With  few  exceptions,  the
competitive  nature of the power supply industry has placed  continual  downward
pressure on selling prices.  In order to achieve low cost  manufacturing  with a
labor-intensive product, manufacturers have the option of automating much of the
labor out of their  product,  or  producing  their  product  in a low labor cost
environment.  Given the high fixed costs of automation and the  resistance  this
places on making major product changes, Digital Power believes that its flexible
manufacturing  strategy  is best  achieved  through  a highly  variable  cost of
operation.  In 1986,  the  Company  established  a  wholly-owned  subsidiary  in
Guadalajara,  Mexico to  assemble  its  products.  This  manufacturing  facility
performs materials management,  sub-assembly, final assembly, and test functions
for the majority of the Company's power supply products.  Currently,  almost all
of the Company's manufacturing, including its value-added services, is done at a
16,000 square foot facility operated by the Company's  wholly-owned  subsidiary,
Poder  Digital,  S.A. de C.V.,  located in  Guadalajara,  Mexico.  In  addition,
Digital  Power has  entered  into an  agreement  with  Fortron/Source  Corp.  to
manufacture Digital Power's products at a facility located in China on a turnkey
basis.  Purchases from  Fortron/Source  will be made pursuant to purchase orders
and the  agreement  may be  terminated  upon 120 days  notice.  The  Company  is
manufacturing   approximately   15%  of   its   product   requirements   through
Fortron/Source  and  expects  to  increase  these production levels due to  cost

<PAGE>10

advantages achieved through Chinese  procurement.  The Company believes that the
facility in China complements its manufacturing facility in Guadalajara,  Mexico
since the facility in China allows the Company to produce  power  supplies  with
sufficient  lead  time at lower  costs,  while  the  Guadalajara  facility  will
continue  to  manufacture  power  supplies  that  need  a  quick  turnaround  or
modification.

Sales, Marketing and Customers

        During 1998, the Company had revenues of  $18,733,470  and a net loss of
$570,588 compared to revenues of $18,884,259 and net income of $1,400,790 during
fiscal year 1997.

        Digital  Power  markets  its  products  through  a network  of  thirteen
domestic  and one  Canadian  independent  manufacturers'  representatives.  Each
representative  organization  is responsible  for managing sales in a particular
geographic territory.  Generally, the representative has exclusive access to all
potential  customers in the assigned territory and is compensated by commissions
at 5% of net sales after the product is shipped,  received,  and paid for by the
customer.  Typically,  either the Company or the representative organization may
terminate the agreement with 30 days' written notice.

        In certain territories,  the Company has entered into agreements with 23
stocking distributors who buy and resell the Company's products.  For the fiscal
years ended December 31, 1998 and 1997,  distributor  sales accounted for 26.07%
and 44.3%,  respectively,  of the Company's total sales.  Over this same period,
one distributor  accounted for 13% and 24.9%,  respectively,  of total sales. In
addition,  international sales through stocking distributors  accounted for less
than 5% of the  Company's  sales.  In  general,  the  agreements  with  stocking
distributors  are subject to annual renewal and may be terminated  upon 90 days'
written notice.  Although these  agreements may be terminated by either party in
the event a stocking  distributor  decides to terminate its  agreement  with the
Company,  the Company believes that it would be able to continue the sale of its
products  through  direct sales to the  customers  of the stocking  distributor.
Further,  and in general,  stocking  distributors  are eligible to return 25% of
their previous six- months' sales for stock rotation.  For the past three years,
stock rotations have not exceeded one percent of total sales.

        The Company has also entered into agreements  with three  private  label
customers who buy and resell the Company's products. Under these agreements, the
Company  sells its  products to the private  label  company who then resells the
products  with its label to its  customers.  The  Company  believes  that  these
private  label  agreements  expand its market by offering  the customer a second
source  for  the  Company's  products.  The  private  label  agreements  may  be
terminated by either party.  Further,  the private label agreement requires that
any product  subject to a private  label be  available  for five years.  For the
years ended December 31, 1998 and 1997,  private label sales  accounted for 8.0%
and 13.9%, respectively, of total sales.

        The Company's  promotional  efforts to date have  included  product data
sheets,  feature articles in trade  periodicals,  and trade shows. The Company's
future   promotional   activities  will  likely  include  space  advertising  in
industry-specific  publications, a full-line product catalog, application notes,
and direct mail to an industry-specific mail list.

<PAGE>11

        The Company's  products are warranted to be free of defects for a period
ranging from one to two years from date of  shipment.  No  significant  warranty
returns  were  experienced in either 1998 or 1997.  As of December 31, 1998, the
Company's warranty reserve was $305,000.

Competition

        The merchant power supply  manufacturing  industry is highly  fragmented
and characterized by intense  competition.  The Company's  competition  includes
over 500 companies  located  throughout the world,  some of whom have advantages
over the  Company in terms of labor and  component  costs,  and some of whom may
offer  products  comparable  in quality to those of the Company.  Certain of the
Company's  competitors,  including Artesyn  Technologies,  Inc. (now merged with
Zytec Corporation),  ASTEC America,  and Lambda Electronics,  have substantially
greater  fiscal and marketing  resources and  geographic  presence than does the
Company.  If the Company  continues to be successful in increasing its revenues,
competitors may notice and increase competition for the Company's customers. The
Company also faces  competition  from current and prospective  customers who may
decide to design and manufacture  internally the power supplies needed for their
products.  Furthermore,  certain  larger OEMs tend to contract  only with larger
power supply  manufacturers.  This factor could become more  problematic  to the
Company if consolidation trends in the electronics industry continue and some of
the OEMs to whom the Company  sells its products are acquired by larger OEMs. To
remain  competitive,  management  believes  that the  Company  must  continue to
compete  favorably  on the basis of value by  providing  advanced  manufacturing
technology,  offering superior customer service and design engineering services,
continuously improving quality and reliability levels, and offering flexible and
reliable delivery schedules.  The Company believes it has a competitive position
with its targeted  customers who need a high-quality,  compact product which can
be readily modified to meet the customer's unique requirements.  However,  there
can be no assurance  that the Company will continue to compete  successfully  in
the power supply market.

Research and Development

        The Company's  research and development  efforts are primarily  directed
toward the  development  of new  standard  power supply  platforms  which may be
readily modified to provide a broad array of individual models. Improvements are
constantly  sought in power density,  modifiability,  and efficiency,  while the
Company   attempts  to  anticipate   changing   market   demands  for  increased
functionality,  such as PFC and improved  EMI  filtering.  Internal  research is
supplemented  through the  utilization of consultants  who specialize in various
areas,  including component and materials engineering and electromagnetic design
enhancements  to improve  efficiency,  while  reducing  the cost and size of the
Company's  products.   Product  development  is  performed  at  Digital  Power's
headquarters  in California by three engineers who are supported and assisted by
five technicians.  The Company's total expenditures for research and development
were  $1,397,816  and $866,787  for the years ended  December 31, 1998 and 1997,
respectively,  and  represented  7.46% and 4.59% of the Company's total revenues
for the corresponding periods.

Employees

        As of December 31, 1998,  the Company had  approximately  340  full-time
employees,  with 255 of these  employed  at its  wholly-owned  subsidiary  Poder
Digital located in Guadalajara,  Mexico,  and 50 employed by Gresham Power.  The
employees  of  Digital Power's Mexican operation are members of a national labor

<PAGE>12

union,  as are  most  employees  of  Mexican  companies.  The  Company  has  not
experienced  any work  stoppages  at either of its  facilities  and believes its
employee relations are good.

Guadalajara, Mexico Facility and Foreign Currency Fluctuations

        The Company  produces  substantially  all of its  products at its 16,000
square foot  facility  located in  Guadalajara,  Mexico.  The  products are then
delivered  to Fremont,  California  for testing  and  distribution.  The Company
believes  that  it  has a  good  working  relationship  with  its  employees  in
Guadalajara,  Mexico and has recently signed a five-year contract with the union
representing  the  employees.  In 1997,  the  Company  entered  into a "turnkey"
manufacturing  contract  with a  manufacturer  located in China to  produce  its
products in an attempt to reduce its dependence on its Mexican facility. At this
time the purchase of products from the  manufacturer  located in China  accounts
for approximately 15% of revenues and requires advance  scheduling which affects
the Company's  ability to produce products  quickly.  However,  if the Company's
revenues grow as  anticipated,  the Company  intends to manufacture  more of its
products  utilizing  the  Chinese  manufacturer.  In the event  that there is an
unforeseen  disruption at the Guadalajara  production  plant or with the Chinese
manufacturer,  such  disruption  may have an  adverse  effect  on the  Company's
ability to deliver its products and may adversely affect the Company's financial
operations.

        Further,  the  Guadalajara,   Mexico  facility  conducts  its  financial
operations  using the Mexican  peso and Gresham  Power  conducts  its  financial
operation using the United Kingdom pound. Therefore, due to financial conditions
beyond  the  control  of  the  Company,  the  Company  is  subject  to  monetary
fluctuations  between the U.S.  dollar,  Mexican peso, and United Kingdom pound.
During  fiscal  1998,   the  Company  lost  $37,771  as  a  result  of  currency
fluctuations.

                             CERTAIN CONSIDERATIONS

        In addition  to the other  information  presented  in this  report,  the
following  should be  considered  carefully  in  evaluating  the Company and its
business. This report contains various  forward-looking  statements that involve
risks and uncertainties. The Company's actual results may differ materially from
the results  discussed  in the  forward-looking  statements.  Factors that might
cause such a difference  include,  but are not limited to, those discussed below
and elsewhere in this report.

Customer Concentration

        Traditionally,  the Company has relied on a limited  number of customers
for growth and increase in sales.  For the fiscal year ended  December 31, 1997,
one OEM accounted for 24.9% of the Company's  total revenues which  subsequently
ceased purchases during the fourth quarter of 1997. See "Management's Discussion
and Analysis or Plan of  Operation."  For the year ended  December 31, 1998, one
OEM customer  accounted for 13% of the Company's total revenue.  The loss of any
major OEM customers may have an adverse effect on the Company's revenues.

$3 Million Credit Facility

        The Company has entered into a $3 million credit  facility with San Jose
National  Bank.  As  of  December  31,  1998,  approximately  $1.6  million  was
outstanding.  The  credit  facility bears interest based upon the lender's prime

<PAGE>13

rate, is due June 15, 1999, and is secured by all of the Company's assets. Under
terms of the loan agreement,  the Company is in technical default requiring that
the Company be  profitable  on a quarterly  basis and  maintain  certain debt to
tangible net worth  ratios.  The Company has obtained a wavier of the  covenants
from the bank.  However,  in the event the Company continues to be unprofitable,
no assurance  can be given that the bank will continue to waive the covenants or
renew the Company's loan.

Dependence on Computer and Other  Electronic  Equipment  Industries;  Customers'
Product Obsolescence

        Substantially  all  of  the  Company's  existing  customers  are  in the
computer and other  electronic  equipment  industries and produce products which
are subject to rapid technological change, obsolescence,  and large fluctuations
in product demand. These industries are characterized by intense competition and
a demand on OEMs serving  these markets for increased  product  performance  and
lower product  prices.  Given this industry  environment  in which they operate,
OEMs make similar demands on their suppliers, such as the Company, for increased
product  performance and lower product prices.  Thus, in order to be successful,
the  Company  must  properly  assess  developments  in the  computer  and  other
electronic  equipment  industries and identify product groups and customers with
the potential for continued and future  growth.  Factors  affecting the computer
and other electronic equipment  industries,  in general, or any of the Company's
major customers or their products, in particular,  could have a material adverse
effect on the  Company's  results  of  operations.  In  addition,  the  computer
industry is inherently volatile.  Recently, certain segments of the computer and
other  electronic  industries  have  experienced a softening in demand for their
products.  Although this has not materially affected the Company's customers, in
the event that it affects all  segments  of the  computer  and other  electronic
industries, the growth of the Company could be adversely affected.

Dependence on Guadalajara, Mexico Facility; Foreign Currency Fluctuations

        The Company produces  substantially  all of its products at its facility
located in  Guadalajara,  Mexico.  The products  are then  delivered to Fremont,
California for testing and distribution. The Company believes that it has a good
working relationship with its employees in Guadalajara,  Mexico and has signed a
five-year  contract with the union  representing the employees.  The Company has
also entered into a "turnkey" manufacturing contract with a manufacturer located
in China to produce its products in an attempt to reduce its  dependence  on its
Mexican  facility.  At this time the purchase of products from the  manufacturer
located in China accounts for approximately 15% of revenues and requires advance
scheduling  which affects the  Company's  ability to produce  products  quickly.
However,  the Company may manufacture more of its products utilizing the Chinese
manufacturer.  In the  event  that  there  is an  unforeseen  disruption  at the
Guadalajara  production plant or with the Chinese manufacturer,  such disruption
may have an adverse effect on the Company's  ability to deliver its products and
may adversely affect the Company's financial operations.

Dependence Upon Key Personnel

        The Company's performance is substantially  dependent on the performance
of its executive  officers and key  personnel,  and on its ability to retain and
motivate  such  personnel.  The  loss  of any of the  Company's  key  personnel,
particularly  Robert O. Smith,  Chief Executive  Officer,  could have a material
adverse effect on the Company's  business,  financial  condition,  and operating
results.  The  Company  has "key person" life insurance policies on Mr. Smith in

<PAGE>14

the aggregate amount of $2 million. The Company also has an employment agreement
with Mr. Smith.

Dependence on Suppliers

        In order to reduce dependence on any one supplier,  the Company attempts
to obtain two suppliers for each  component of its  products.  However,  for one
line transformer in its product,  the Company is dependent on a single supplier.
Currently, this product accounts for less than 10% of the Company's total sales.
Although the Company will seek to find other  manufacturers  of transformers for
this  product,  unanticipated  shortages  or delays  in these  parts may have an
adverse effect on the Company's results of operations.

No Patents

        The Company's  products are not subject to any U.S. or foreign  patents.
The Company believes that because its products are being continually updated and
revised,  obtaining patents would not be beneficial.  Therefore, there can be no
assurance  that  other  competitors  or former  employees  will not  obtain  the
Company's proprietary information and develop it.

Item 2.  Description of Properties.

        The Company's  headquarters  are located in  approximately  9,500 square
feet of leased office,  research and development  space in Fremont,  California.
The Company pays $5,890 per month, subject to adjustment,  and the lease expires
on January 31, 2001. The Company's  manufacturing  facility is located in 16,000
square  feet  of  leased  space  in  Guadalajara,   Mexico.   The  Company  pays
approximately $3,500 per month, subject to adjustment,  and the lease expires in
February  2001.  Gresham Power leases  approximately  25,000 square feet for its
location  in  Salisbury,  England.  Gresham  Power  pays  rent of  approximately
(pound)17,500 per quarter, and the lease will expire September 26, 2009. Gresham
Power is currently negotiating to enter into a new lease with the landlord.  The
Company  believes that its existing  facilities are adequate for the foreseeable
future and has no plans to expand them.

Item 3.  Legal Proceedings.

        On April 20,  1998,  the  Company  was served  with a  complaint  in the
Superior  Court of  California  in and for the County of Santa  Clara  (Case No.
CV773108) by KDK  Electronics,  Inc. In its complaint,  KDK Electronics  alleged
breach of contract,  misappropriation  of trade  secrets,  fraud,  and negligent
misrepresentation  in connection with, among other things, the Company's alleged
failure  to pay KDK  Electronics  royalties  on  sales  of  products  that  were
allegedly  derived  from KDK  Electronic's  designs,  and for  failure  to issue
100,000  shares of the  Company's  Common  Stock  based on  revenues  from those
products.  KDK  Electronic's  complaint seeks economic  damages of approximately
$300,000, punitive and exemplary damages, injunctive relief, attorneys' fees and
costs.

         In  connection  with  litigation  involving  KDK  Electronics  and  the
Company,  on September 3, 1998, the Company  entered into a Technology  Transfer
Agreement  with KDK  Electronics.  Under  the terms of the  Technology  Transfer
Agreement, the Company acquired from KDK Electronics the technology and right to
sell in the  future  products  that may be  derived  under  the  1987  licensing
agreement,  as  amended,  between  KDK  Electronics  and  the  Company.  For the

<PAGE>15

acquisition  of the  technology  and  future  sales  rights  and  settlement  of
litigation,  the Company  issued  35,000 shares of its common stock and will pay
$150,000 in $7,000 monthly payments,  beginning in October 1998. Further,  under
the terms of the settlement agreement, each party bore its own expenses.

        On March 17, 1998, a lawsuit was filed by Ignacio  Valencia  against the
Company in the  Superior  Court of Santa Clara  County (No.  CV772665)  alleging
deceit and breach of contract.  In the complaint,  Mr. Valencia  alleged that in
1986, Mr. Valencia moved his family to  Guadalajara,  Mexico on reliance that he
would become  president of Poder Digital S.A. de C.V.  ("Poder"),  the Company's
wholly-owned subsidiary and would receive forty percent of the profits of Poder.
Mr.  Valencia  claimed lost wages of $52,000 and lost stock  options of $350,000
and punitive damages.

        On February 12, 1999, the Company settled the lawsuit with Mr. Valencia.
Under the terms of the  settlement,  the Company paid Mr.  Valencia  $16,110 and
will  provide  Mr.  Valencia  employment  for six months at the  hourly  rate of
$18.50,  40 hours per week. Mr Valencia's  term of employment will end on August
13, 1999. In connection  with the settlement,  Mr. Valencia  dismissed his claim
with prejudice.

        Digital  Power's  Common  Stock and  Redeemable  Common  Stock  Purchase
Warrants are listed and traded on the American Stock Exchange ("AMEX") under the
symbols DPW and DPW+,  respectively.  Prior to being  listed and traded on AMEX,
Digital Power's Common Stock and Redeemable  Common Stock Purchase Warrants were
traded on the NASDAQ SmallCap  Market.  The following  tables set forth the high

Item 6.  Management's Discussion and Analysis or Plan of Operation.

Overview

        The Company  designs,  develops,  manufactures,  and markets  electronic
power supplies for use in converting electric power into a form suitable for the
operation  of  electronic circuitry. Revenues are generated from the sale of the

<PAGE>17

Company's power supplies to OEMs in the computer and other electronic  equipment
industries.

        In January 1998, the Company  acquired  certain assets of Gresham Power.
Similar to Digital Power,  Gresham Power designs,  manufactures  and distributes
switching   power  supplies,   uninterruptible   power  supplies  and  frequency
converters  for  the  commercial  and  military  markets.  As a  result  of  the
acquisition  of  Gresham  Power,  the  Company's   Consolidated  Balance  Sheet,
Consolidated  Statements  of Income,  Consolidated  Statement  of  Stockholders'
Equity and Consolidated Statements of Cash Flows for the year ended December 31,
1998,  include the financial  statements of Gresham Power from January 22, 1998,
the date of acquisition.

the Company's  Consolidated Financial Statements and the notes thereto and other
financial information included elsewhere in this report.

<PAGE>18


Year Ended December 31, 1998, Compared to Year Ended December 31, 1997

Revenues

        Revenues for the fiscal year ended December 31, 1998,  were  $18,733,470
which represented a decrease of $150,789,  or approximately 1%, from revenues of
$18,884,259  for the year ended  December 31, 1997. The decrease in revenues was
due primarily to the loss of the Company's  largest customer which accounted for
approximately  24.4% of the  Company's  revenues  during 1997.  This decrease in
total revenues was offset by an increase in revenues of $7,002,041  from Gresham
Power which was acquired in January 1998.

Gross Margins

        Gross margins were 21.11% for the year ended  December 31, 1998 compared
to 26.10% for the fiscal year ended  December 31, 1997.  This  decrease in gross
margins can be primarily  attributed to an increase in cost of goods sold due to
price erosion of inventory, the write off certain slow moving inventory, and the
increase in warranty reserves.

Selling, General and Administrative

        Selling,  general and  administrative  expenses  increased by $1,540,446
to  $3,134,211  for the year ended  December 31, 1998, from  $1,593,765  for the
fiscal year ended  December 31, 1997. Of the increase,  $1,289,006 is attributed
to Gresham  Power.  The other  additional  increase is  primarily  related to an
increase in provision of bad debts and for professional fees.

Engineering and Product Development

        Engineering  and product  development  expenses were  $1,397,816 for the
year ended  December  31,  1998,  as  compared  to  $866,787  for the year ended
December 31, 1997. Of the increase, $280,514 is attributed to Gresham Power. The
other  additional  increase  can  be  attributed  to  expenses  related  to  the
development  of the UPF 150 and another new  product  and to the  settlement  of
litigation involving KDK Electronics.

Interest Expense

        Net interest  expense was $220,894 for the year ended December 31, 1998,
compared to $21,542  for the year ended  December  31,  1997.  This  increase in
interest  expense is primarily  due to  increased  borrowings  of  approximately
$1,700,000 to acquire Gresham Power in January 1998.

Translation Loss

        The primary currency of the Company's subsidiary,  Poder Digital, is the
Mexican peso and for Gresham Power,  the United Kingdom pound.  During 1998, the
Company  experienced a translation  loss of $37,771  primarily  related to Poder
Digital's  operations  using Mexican pesos,  compared with a translation loss of
$19,846 in 1997.

<PAGE>19

(Loss) Income Before Income Taxes

        The Company  incurred a loss of  ($828,588)  before  income taxes during
1998  compared  to  income  before  income  taxes of  $2,426,790  in 1997.  This
substantial decrease, as  discussed  above was due to the loss of the  Company's
largest  customer  during the end of 1997,  softness in the power supply market,
and  erosion  of  the  Company's  gross  margin,   and  increased  research  and
developments expenses.

Income Tax

        For the year ended  December  31,  1998,  the  Company had an income tax
benefit  of  $258,000  due to its 1998  net  loss  compared  to tax  expense  of
$1,026,000 for the year ended December 31, 1997.

Net (Loss) Income

        Net loss was  ($570,588) in 1998 compared to net income of $1,400,790 in
1997.

        The Company does not believe that its business is seasonal.

Liquidity and Capital Resources

        Through  December 31, 1998, the Company funded its operations  primarily
through revenues generated from operations,  and bank borrowings. As of December
31,  1998,  the Company had cash and cash  equivalents  of $867,607  and working
capital  of  $5,001,316.  This  compares  with  cash  and  cash  equivalents  of
$2,205,299 and working  capital of $7,050,144 at December 31, 1997. The decrease
in working capital for the year ended December 31, 1998, is primarily due to the
Company's loss and borrowings to acquire  Gresham Power.  Cash provided by (used
in) operating  activities for the Company  totaled $10,066 and $(80,252) for the
year ended  December  31, 1998 and 1997,  respectively.  Cash used in  investing
activities of $3,500,586 during 1998 consisted of primarily expenditures for the
purchase of the assets of Gresham  Power.  During  1997,  cash used in investing
activities  amounted to $388,825  from the  purchase of  production  and testing
equipment.  For the year  ended  December  31,  1998,  cash flow from  financing
activities included proceeds from borrowings of $2,366,846 offset by proceeds of
$95,350 from the exercise of warrants and stock options and payments of $300,505
on  borrowings.  During the year ended  December 31, 1997, the Company's line of
credit and bank loans, other than the ESOP, were paid in full.

        The  Company  is a  guarantor  of a  $500,000  term loan  granted to the
Company's  employee stock  ownership plan ("ESOP").  The balance  outstanding of
$184,919  related  to this term  loan is  included  in the  total  amount of the
Company's  bank  borrowings  as of December  31, 1998,  stated in the  preceding
paragraph.  The  loan is due in June 2001, and bears interest at 8.5% per annum.
Proceeds  from  the  loan were used to acquire the Company's common stock by the
ESOP.  Principal  and  interest  on  the  loan  will be paid by the ESOP through
contributions  made by the  Company to the ESOP in the  amount of  approximately
$8,852 per month. This amount will be a monthly charge to expense.

        Impact of the Year 2000  Issue.  The Year  2000  Issue is the  result of
computer  programs being written using two digits rather than four to define the
applicable year. Any of the Company's, or its suppliers' and customers' computer
programs  that have  date-sensitive  software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in system failures or

<PAGE>20

miscalculations causing disruptions of operations including, among other things,
a temporary  inability  to process  transactions,  send  invoices,  or engage in
similar normal business activities.

        The Company upgraded its software at a cost of less than $10,000 and has
been informed by its suppliers  that such software is Year 2000  compliant.  The
software from these suppliers is used in major areas of the Company's operations
such as for financial,  sales,  warehousing  and  administrative  purposes.  The
Company has no internally  generated software.  The Company believes that all of
its hardware is Year 2000  compliant.  In  connection  with the  acquisition  of
Gresham Power, the Company has determined that Gresham Power's existing software
will not be Year 2000  compliant,  and has acquired new hardware and software to
address the Year 2000 issue at a cost of approximately  $150,000 to make Gresham
Power Year 2000  compliant.  The Company  anticipates  that  Gresham  Power will
complete the  installation  of hardware  and  software  during the first part of
1999. Other than Gresham Power, and after reasonable investigation,  the Company
has not yet  identified any other Year 2000 problem but will continue to monitor
the issue.  However,  there can be no assurances that the Year 2000 problem will
not occur with respect to the Company's computer systems.

        The Company and its  subsidiaries  intend,  but have not yet,  initiated
formal   communications  with  significant  suppliers  and  large  customers  to
determine the extent to which those third  parties'  failure to remedy their own
Year 2000 Issues would materially  effect the Company and its  subsidiaries.  In
the event that the Company  receives  indications  from its  suppliers and large
customers  that the Year 2000  Issue may  materially  effect  their  ability  to
conduct business,  the Company will seek contingency plans such as finding other
vendors that are Year 2000  compliant  or increase its  inventory of supplies or
parts in an attempt to ensure smooth operations until such vendor can remedy the
problem.

Impact of Recently Issued Standards

        In June 1998, the Financial  Accounting Standards Board issued Statement
of Financial Accounting Standards No. 133 (FASB133),  "Accounting for Derivative
Instruments  and Hedging  Activities."  This  statement is effective  for fiscal
years beginning after June 15, 1999. Earlier application is encouraged; however,
the Company does not anticipate adopting FASB133 until the fiscal year beginning
January 1, 2000.  FASB133  requires that an entity  recognize all derivatives as
assets or liabilities  in the statement of financial  position and measure those
instruments at fair value.  The Company does not believe the adoption of FASB133
will have a material  impact on assets,  liabilities or equity.  The Company has
not yet determined  the impact of FASB133 on the income  statement or the impact
on comprehensive income.

        FASB132, "Employers' Disclosures About Pensions and Other Postretirement
Benefits" and FASB134, "Accounting for Mortgage-Backed Securities Retained After
the  Securitization  of  Mortgage  Loans  Held  for Sale by a  Mortgage  Banking
Enterprise"  were issued in 1998 and are not  expected  to impact the  Company's
future  financial  statement  disclosures,  results of operations  and financial
position.

                          INDEPENDENT AUDITOR'S REPORT


To the Stockholders and Board of Directors
Digital Power Corporation and Subsidiaries
Fremont, California


We have audited the  accompanying  consolidated  balance  sheet of Digital Power
Corporation  and   Subsidiaries  as  of  December  31,  1998,  and  the  related
consolidated   statements   of   operations,    comprehensive   income   (loss),
stockholders'  equity,  and cash flows for the years ended December 31, 1998 and
1997.  These  financial  statements  are  the  responsibility  of the  Company's
management.  Our  responsibility is to express an opinion on these  consolidated
financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly,  in all  material  respects,  the  financial  position of Digital  Power
Corporation  and  Subsidiaries as of December 31, 1998, and the results of their
operations  and their cash flows for the years ended December 31, 1998 and 1997,
in conformity with generally accepted accounting principles.

                   DIGITAL POWER CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   ORGANIZATION AND NATURE OF OPERATIONS:

Digital  Power  Corporation  ("DPC"),  and one of its wholly owned  subsidiaries
Poder Digital, S.A. de C.V. ("PD"), which is located in Guadalajara, Mexico, are
engaged in the design, manufacture and sale of switching power supplies.

On January 26, 1998, DPC acquired the assets and assumed certain  liabilities of
Gresham  Power  Electronics,  a division  of Gresham  Lion  Technology  Ltd.,  a
European  corporation,  through a newly-formed  subsidiary Digital Power Limited
("DPL"). (See Note 3.) DPL is also engaged in the design, manufacture,  and sale
of switching power supplies.

DPC, PD, and DPL are collectively referred to as the "Company".


2.   SIGNIFICANT ACCOUNTING POLICIES:

Principles of Consolidation - The consolidated  financial statements include the
accounts of the  Company  and its wholly  owned  subsidiaries.  All  significant
intercompany accounts and transactions have been eliminated in consolidation.

Statements  of Cash Flows - For purposes of the  statements  of cash flows,  the
Company considers all highly liquid debt instruments  purchased with an original
maturity of three months or less to be cash equivalents.

Inventories - Inventories are stated at the lower of cost (first-in,  first-out)
or market.

Property and Equipment - Property and equipment are stated at cost. Depreciation
of equipment and furniture is calculated using the straight-line method over the
estimated  useful lives (ranging from 5 to 10 years) of the  respective  assets.
Leasehold  improvements are amortized over the shorter of their estimated useful
life or the term of the lease.  The cost of normal  maintenance  and  repairs is
charged to operations as incurred. Material expenditures which increase the life
of an asset are capitalized and depreciated over the estimated  remaining useful
life of the asset. The cost of fixed assets sold, or otherwise  disposed of, and
the related  accumulated  depreciation  or  amortization  are  removed  from the
accounts, and any resulting gains or losses are reflected in current operations.

Excess of Purchase  Price Over Net Assets  Acquired - Excess of  purchase  price
over net assets acquired ("Goodwill") represents the purchase price in excess of
the fair value of the net assets of the acquired business and is being amortized
using the straight-line  method over its estimated useful life of ten years. The
carrying value is evaluated at least  annually.  The Company  considers  current
facts and  circumstances,  including  expected future  operating income and cash
flows to determine whether it is probable that impairment has occurred.

Income Taxes - The Company accounts for income taxes under the liability method,
which  requires  recognition  of  deferred  tax assets and  liabilities  for the
expected  future  tax  consequences  of events  that have been  included  in the
financial statements or tax returns. Under this method,  deferred tax assets and
liabilities  are  determined  based  on the  difference  between  the  financial
statements  and tax basis of assets and  liabilities  using enacted tax rates in
effect for the year in which the differences are expected to reverse.

Revenue  Recognition - Sales revenue is recognized when the products are shipped
to  customers,  including  distributors.  Customers  receive  a one or  two-year
product  warranty  and certain  sales to  distributors  are subject to a limited
right of return. The Company provides a reserve for estimated warranty costs and
a reserve for estimated product returns.

Foreign Currency  Translation - Assets and liabilities of the Company's  foreign
subsidiaries are translated into U.S. dollars at year-end exchange rates. Income
and expense items are translated at average exchange rates prevailing during the
year.  The resulting  translation  adjustment for DPL is recorded as accumulated
other  comprehensive  income,  a component of  stockholders  equity.  Because PD
operates  in a  country  with a highly  inflationary  economy,  any  translation
adjustment is included in the results of operations.

Earnings Per Share - Basic earnings per share excludes  dilution and is computed
by dividing  income  (loss)  available  to common  stockholders  by the weighted
average number of common shares outstanding for the period. Diluted earnings per
share  reflects the  potential  dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock or
resulted in the issuance of common stock that then shared in the earnings of the
entity.  Common  stock  equivalents  for the year ending  December 31, 1998 were
anti-dilutive and excluded in the earnings per share computation.

Accounting  Estimates - The  preparation  of financial  statements in conformity
with  generally  accepted  accounting  principles  requires  management  to make
estimates  and  assumptions  that affect the amounts  reported in the  financial
statements  and the  accompanying  notes.  The actual  results could differ from
those estimates.

The  Company's  financial  statements  are based  upon a number  of  significant
estimates   including  the  allowance  for  doubtful   accounts,   technological
obsolescence  of inventories,  the estimated  useful lives selected for property
and equipment and goodwill,  realizability of deferred tax assets, allowance for
sales returns,  and warranty reserve.  Due to the uncertainties  inherent in the
estimation process, it is at least reasonably possible that these estimates will
be further revised in the near term and such revisions could be material.

Impairment  of  Long-Lived  Assets - In the event that  facts and  circumstances
indicate  that the cost of long-lived  assets may be impaired,  an evaluation of
recoverability would be performed.  If an evaluation is required,  the estimated
future  undiscounted  cash flows  associated with the asset would be compared to
the asset's  carrying  amount to determine  if a  write-down  to market value or
discounted cash flow value is required.

Stock-Based  Compensation  -  The  Company  has  elected  to  follow  Accounting
Principles  Board  Opinion No. 25,  "Accounting  for Stock Issued to  Employees"
(APB25)  and  related  interpretations  in  accounting  for its  employee  stock
options.  In accordance  with FASB Statement No. 123 "Accounting For Stock-Based
Compensation"  (FASB123),  the Company will  disclose the impact of adopting the
fair  value  accounting  of  employee  stock  options.  Transactions  in  equity
instruments  with  non-employees  for goods or services have been  accounted for
using the fair value method prescribed by FASB123.

Concentrations  of Credit Risk - Credit risk represents the accounting loss that
would be recognized at the reporting date if counterparties failed completely to
perform as contracted.  Concentrations of credit risk (whether on or off balance
sheet) that arise from  financial  instruments  exist for groups of customers or
groups of counterparties  when they have similar economic  characteristics  that
would  cause  their  ability to meet  contractual  obligations  to be  similarly
effected by changes in economic or other  conditions.  In  accordance  with FASB
Statement No. 105,  "Disclosure of Information about Financial  Instruments with
Off-Balance-Sheet  Risk and Financial  Instruments With Concentrations of Credit
Risk," the credit risk amounts  shown,  in Note 13, do not take into account the
value of any collateral or security.

Fair Value of Financial  Instruments - The  estimated  fair values for financial
instruments  under FASB  Statement  No.  107,  "Disclosures  about Fair Value of
Financial  Instruments,"  are  determined  at  discrete  points in time based on
relevant market information. These estimates involve uncertainties and cannot be
determined with precision.

The following methods and assumptions were used in estimating the indicated fair
values of the Company's financial instruments:

     Cash and cash  equivalents:  The carrying  amount  approximates  fair
     value because of the short maturity of those instruments.

     Long-term  and other debt:  The fair value of the  Company's  debt is
     estimated  based on current  rates offered to the Company for similar
     debt and approximates carrying value.

Comprehensive  Income  -  The  Company  has  adopted  the  Financial  Accounting
Standards Board Statement of Financial  Accounting Standards No. 130, "Reporting
Comprehensive  Income" (FASB130).  FASB130 defines  comprehensive  income as all
changes in stockholders'  equity exclusive of transactions with owners,  such as
capital  investments.  Comprehensive  income  includes  net  income  or loss and
changes in certain assets and liabilities that are reported  directly in equity,
such  as,  translation  adjustments  on  investments  in  foreign  subsidiaries,
difference in the recognition of  compensation  expense for books versus tax for
employee stock options, and certain changes in minimum pension liabilities.

Impact of Recently  Issued  Standards - In June 1998,  the Financial  Accounting
Standards  Board  issued  Statement of Financial  Accounting  Standards  No. 133
(FASB133),  "Accounting for Derivative Instruments and Hedging Activities". This
statement is effective for fiscal years beginning  after June 15, 1999.  Earlier
application is  encouraged;  however,  the Company does not anticipate  adopting
FASB133 until the fiscal year beginning  January 1, 2000.  FASB133 requires that
an entity recognize all derivatives as assets or liabilities in the statement of
financial position and measure those instruments at fair value. The Company does
not  believe  the  adoption  of FASB133  will have a material  impact on assets,
liabilities or equity.  The Company has not yet determined the impact of FASB133
on the income statement or the impact on comprehensive income.

FASB132,   "Employers'  Disclosures  about  Pensions  and  Other  Postretirement
Benefits" and FASB134, "Accounting for Mortgage-Backed Securities Retained after
the  Securitization  of  Mortgage  Loans  Held  for Sale by a  Mortgage  Banking
Enterprise"  were issued in 1998 and are not  expected  to impact the  Company's
future  financial  statement  disclosures,  results of operations  and financial
position.

Reclassifications - Certain reclassifications have been made to the prior year's
consolidated financial statements to conform with the current presentation. Such
reclassifications had no effect on net income (loss).

3.   ACQUISITION:

In January 1998, the Company entered into an agreement to acquire certain assets
and assume  certain  liabilities  of Gresham  Power  Electronics,  a division of
Gresham Lion Technology Ltd., a European  Corporation.  The total purchase price
including  acquisition  costs was $3,370,293 with $1,452,190  being allocated to
excess of purchase price over net assets acquired.

Gresham  Power  Electronics  had no  material  activity  for  1998  prior to the
acquisition,  therefore the statements presented for the year ended December 31,
1998 resemble those that would be shown in a pro forma.  The following  presents
unaudited pro forma information as if the acquisitions  described above occurred
on January 1, 1997:

As part of the public  offering,  the  underwriter  was  allocated an additional
150,000  shares at $4.00 per share and 75,000  warrants  at $.125 per warrant to
cover over-allotments, if any. On January 8, 1997, the underwriter exercised and
sold the over allotment shares and warrants for net proceeds of $492,378.

                                 PREFERRED STOCK

The  preferred  stock  has one  series  authorized,  500,000  shares of Series A
cumulative   redeemable   convertible  preferred  stock  ("Series  A"),  and  an
additional  1,500,000  shares of preferred  stock has been  authorized,  but the
rights,  preferences,  privileges and  restrictions on these shares has not been
determined.  DPC's  Board of  Directors  is  authorized  to create new series of
preferred stock and fix the number of shares as well as the rights, preferences,
privileges and  restrictions  granted to or imposed upon any series of preferred
stock.

                                  STOCK OPTIONS

The Company has issued non-qualified options covering 104,922 shares exercisable
at $.50 per share. Upon issuance,  the Company recorded compensation expense for
the  difference  between the  exercise  price and the fair  market  value of the
underlying  common  stock of $1.80 per share.  Such options  expire in 2003.  At
December 31, 1998, 86,900 of such options were outstanding.

In May 1993, the Company issued options to purchase 237,500 shares of its common
stock at $1.80 per share.  Such options are subject to a four-year vesting plan.
The exercise price of $1.80 per share  approximated the fair market value at the
date of grant.  During the years ended  December  31, 1998 and 1997,  12,500 and
55,500,  respectively,  of such options were exercised. 167,000 of these options
are  outstanding at December 31, 1998.  During the year ended December 31, 1997,
2,500 of such options were forfeited.

In May 1996,  the Company  adopted the 1996 Stock Option Plan  covering  513,000
shares.  Under the plan, the Company can issue either incentive or non-statutory
stock options. The price of the options granted pursuant to the plan will not be
less than 100% of the fair market value of the shares on the date of grant.  The
board of directors will decide the vesting period of the options, if any, and no
option will be  exercisable  after ten years from the date granted.  Immediately
thereafter,  the Company issued options to purchase 275,500 shares of its common
stock at $1.80 per share.  Such  options  become  100%  vested  two years  after
issuance.  The  exercise  price was  based  upon  their  terms,  conditions  and
restrictions.  During the years  ended  December  31,  1998 and 1997,  1,000 and

Compensation  cost related to the warrants granted for outside services amounted
to  $46,033  and  $35,903  for the  years  ended  December  31,  1998 and  1997,
respectively. The warrants expire three years after the grant date.


                              PROFORMA INFORMATION

As stated in Note 2, the  Company  has not  adopted  the fair  value  accounting
prescribed by FASB123 for employees.  Had compensation cost for stock options or
warrants  issued to employees been  determined  based on the fair value at grant
date for awards in 1998 and 1997, consistent with the provisions of FASB123, the
Company's  net income  (loss) and net  income  (loss) per share  would have been
reduced to the proforma amounts indicated below:

                                              1998               1997

                                        ==============     ================


The fair value of each option or warrant is estimated on the date of grant using
the present value of the exercise price and is pro-rated based on the percent of
time from the grant date to the end of the vesting period. The  weighted-average
fair  value of the  options  on the grant date was $2.74 and $5.80 per share for
1998 and 1997,  respectively.  The following assumptions were used for grants in
1998 and 1997: average risk-free interest rates of 5.6% and 5.8%,  respectively;
expected lives of five years and two years, respectively;  dividend yield of 0%;
and expected volatility of 69.3% and 56.8%, respectively.

issued upon the close of the  agreement.  The  $150,000  is due in  installments

<PAGE>

        Subject to the express provisions of this Plan, the Administrator  shall
have the  authority  to  construe  and  interpret  this Plan and any  agreements
defining  the rights and  obligations  of the Company and  Optionees  under this
Plan; to further  define the terms used in this Plan; to prescribe,  amend,  and
rescind rules and regulations  relating to the  administration  of this Plan; to
determine the duration and purposes of leaves of absence which may be granted to
Optionees without constituting a termination of their employment for purposes of
this Plan; and to make all other  determinations  necessary or advisable for the
administration of this Plan.

        Any decision or action of the Administrator in connection with this Plan
or Options  granted or shares of Stock  purchased under this Plan shall be final
and binding. The Administrator shall not be liable for any division,  action, or
omission  respecting  this Plan, or any Options  granted or shares of Stock sold
under this Plan.  The Board at any time may abolish the  Compensation  Committee
and revest in the Board the administration of the Plan.

        To the extent  permitted by applicable  law in effect from time to time,
no member of the  Compensation  Committee  or the  Board of  Directors  shall be
liable  for any  action  or  omission  of any other  member of the  Compensation
Committee or the Board of Directors  nor for any act or omission on the member's
own  part,   excepting  only  the  member's  own  willful  misconduct  or  gross
negligence,  arising  out of or  related  to the  Plan.  The  Company  shall pay
expenses incurred by, and satisfy a judgment or fine rendered or levied against,
a present or former director or member of the Compensation Committee or Board in
any action against such person  (whether or not the Company is joined as a party
defendant) to impose liability or a penalty on such person for an act alleged to
have  been  committed  by  such  person  while  a  director  or  member  of  the
Compensation   Committee   or  Board   arising  with  respect  to  the  Plan  or
administration  thereof,  or out of membership on the Compensation  Committee or
Board, or by the Company, or all or any combination of the preceding;  provided,
the director or Compensation  Committee member was acting in good faith,  within
what such director or Compensation  Committee member reasonably believed to have
been within the scope of his or her  employment or authority,  and for a purpose
which he or she  reasonably  believed to be in the best interests of the Company
or its  shareholders.  Payments  authorized  hereunder  include amounts paid and
expenses  incurred  in  settling  any such  action  or  threatened  action.  The
provisions of this section shall apply to the estate,  executor,  administrator,
heirs, legatees, or devisees of a director or Compensation Committee member, and
the term "person" as used in this section  shall  include the estate,  executor,
administrator, heirs, legatees, or devisees of such person.

5.      GRANT OF OPTIONS; TERMS AND CONDITIONS OF GRANT.

        5.1 Grant Of Options. One or more Options may be granted to any Eligible
Person.  Subject to the express provisions of the Plan, the Administrator  shall
determine from the Eligible Persons those  individuals to whom Options under the
Plan  may be  granted.  Each  Option  so  granted  shall  be  designated  by the
Administrator  as either a  Non-qualified  Stock  Option or an  Incentive  Stock
Option.

        Subject to the express provisions of this Plan, the Administrator  shall
specify the Grant Date, the number of shares of Stock covered by the Option, the
exercise price, and the terms and conditions for exercise of the Options. If the
Administrator  fails to specify the Grant Date, the Grant Date shall be the date
of the  action  taken by the  Administrator  to  grant  the  Option.  As soon as
practicable  after the Grant Date, the Company shall provide the Optionee with a
written  Option Agreement in the form approved by the Administrator,  which sets

<PAGE>


out the Grant Date,  the number of shares of Stock  covered by the  Option,  the
exercise price, and the terms and conditions for exercise of the Option.

        The Administrator may, in its absolute  discretion,  grant Options under
this Plan to an  Eligible  Person at any time and from time to time  before  the
expiration of ten (10) years from the Effective Date.

        5.2 General Terms And Conditions.  Except as otherwise  provided herein,
the Options  shall be subject to the  following  terms and  conditions  and such
other terms and conditions not inconsistent  with this Plan as the Administrator
may impose.

        5.3  Exercise Of Option.  In order to exercise all or any portion of any
Option granted under this Plan, an Optionee must remain as an officer, employee,
consultant, or director of the Company, until the Vesting Date. The Option shall
be  exercisable  on or after each Vesting Date in accordance  with the terms set
forth in the Option Agreement.

        5.4 Option Term.  Each Option and all rights or  obligations  thereunder
shall expire on such date as shall be determined by the  Administrator,  but not
later than ten (10) years  after the grant of the Option  (five (5) years in the
case of an Incentive  Stock  Option when the Optionee  owns more than 10% of the
total combined  voting power of all classes of Stock of the Company),  and shall
be subject to earlier termination as hereinafter provided.

        5.5 Exercise Price. The Exercise Price of any Option shall be determined
by the  Administrator,  but in the case of Incentive  Stock Options shall not be
less than 100%  (110% in the case of an  Optionee  who owns more than 10% of the
total combined  voting power of all classes of stock of the Company) of the Fair
Market Value of the Stock on the date the Incentive Stock Option is granted, and
100% of the Fair Market Value of the Stock on the date the  Non-qualified  Stock
Option is granted.

        5.6 Method Of  Exercise.  To the extent the right to purchase  shares of
Stock has accrued,  Options may be exercised,  in whole or in part, from time to
time in accordance  with their terms by written  notice from the Optionee to the
Company  stating the number of shares of Stock with  respect to which the Option
is being  exercised,  and  accompanied by payment in full of the exercise price.
Payment may be made in cash or check.

        5.7  Restrictions  On  Stock;  Option  Agreement.  At the time it grants
Options under this Plan, the Company may retain, for itself or others, rights to
repurchase  the  shares of Stock  acquired  under the  Option,  or impose  other
restrictions  on such  shares.  The terms and  conditions  of any such rights or
other  restrictions  shall be set forth in the Option  Agreement  evidencing the
Option.  No Option  shall be  exercisable  until after  execution  of the Option
Agreement by the Company and the Optionee.

        5.8  Non-Assignability Of Option Rights. No Option shall be transferable
other  than by will or by the  laws of  descent  and  distribution.  During  the
lifetime of an Optionee, only the Optionee may exercise an Option.

<PAGE>

        5.9    Exercise After Certain Events.

               5.9.1 Termination as an employee, director, or consultant. If for
any reason other than permanent and total disability or death (as defined below)
an Optionee  ceases to be employed by or to be a  consultant  or director of the
Company,  Options  held at the  date of such  termination  (to the  extent  then
exercisable) may be exercised, in whole or in part, at any time within three (3)
months after the date of such termination or such lesser period specified in the
Option  Agreement (but in no event after the earlier of (i) the expiration  date
of the Option as set forth in the Option Agreement,  and (ii) ten years from the
Grant Date).

               If an  Optionee  granted an  Incentive  Stock  Option  terminates
employment but continues as a consultant,  advisor,  or in a similar capacity to
the  Company,  Optionee  need not  exercise  the Option  within  three months of
termination of employment but shall be entitled to exercise  within three months
of  termination  of  services  to the  Company  (one  (1)  year in the  event of
permanent  disability or death).  However,  if Optionee does not exercise within
three (3) months of termination of employment, the Option will not qualify as an
Incentive Stock Option.

               5.9.2  Permanent  disability  and death.  If an Optionee  becomes
permanently and totally  disabled (within the meaning of section 22(e)(3) of the
Code),  or dies while  employed by the  Company,  or while acting as an officer,
consultant,  or director of the  Company,(or,  if the  Optionee  dies within the
period that the Option remains  exercisable  after  termination of employment or
affiliation),  Options  then  held  (to  the  extent  then  exercisable)  may be
exercised by the Optionee,  the Optionee's  personal  representative,  or by the
person to whom the  Option is  transferred  by will or the laws of  descent  and
distribution,  in whole or in part,  at any time  within  one (1) year after the
disability or death or any lesser period  specified in the Option Agreement (but
in no event  after the earlier of (i) the  expiration  date of the Option as set
forth in the Option Agreement, and (ii) ten (10) years from the Grant Date).

        5.10 Compliance With Securities Laws. The Company shall not be obligated
to issue any shares of Stock upon  exercise of an Option  unless such shares are
at that time  effectively  registered  or  exempt  from  registration  under the
federal  securities  laws and the  offer  and sale of the  shares  of Stock  are
otherwise in compliance with all applicable securities laws. Upon exercising all
or  any  portion  of  an  Option,   an  Optionee  may  be  required  to  furnish
representations or undertakings  deemed appropriate by the Company to enable the
offer and sale of the shares of Stock or subsequent transfers of any interest in
such shares to comply with applicable securities laws. Evidences of ownership of
shares of Stock acquired upon exercise of Options shall bear any legend required
by, or useful for purposes of compliance with,  applicable securities laws, this
Plan, or the Option Agreement evidencing the Option.

6.      LIMITATIONS ON GRANT OF INCENTIVE STOCK OPTIONS.

        6.1 One Hundred  Thousand  Dollars Rule. The aggregate Fair Market Value
(determined as of the Grant Date) of the Stock for which Incentive Stock Options
may first become exercisable by any Optionee during any calendar year under this
Plan,  together  with that of Stock  subject to Incentive  Stock  Options  first
exercisable  (other than as a result of  acceleration  pursuant to Section 9) by
such  Optionee  under  any other plan of the Company, shall not exceed $100,000.

<PAGE>

        6.2 Option  Agreements.  There shall be imposed in the Option  Agreement
relating to Incentive Stock Options such terms and conditions as are required in
order that the Option be an "incentive  stock option" as that term is defined in
section 422 of the Code.

        6.3 Ten Percent  Rule.  No Incentive  Stock Option may be granted to any
person who, at the time the  Incentive  Stock Option is granted,  owns shares of
outstanding Stock possessing more than 10% of the total combined voting power of
all classes of Stock of the Company, unless the exercise price of such Option is
at least 110% of the Fair Market Value of the Stock  (determined as of the Grant
Date)  subject to the Option,  and such  Option by its terms is not  exercisable
after the expiration of five (5) years from the Grant Date.

        6.4  Non-Employees.  No  Incentive  Stock  Option  may be granted to any
person who is not an employee of the Company.

7.      PAYMENT OF TAXES.

        Upon the  disposition  by an  Optionee  or other  person of shares of an
Option prior to satisfaction  of the holding period  requirements of Section 422
of the Code, or upon the exercise of a Non-qualified  Stock Option,  the Company
shall have the right to require  such  Optionee  or such other  person to pay by
cash, or check payable to the Company, the amount of any taxes which the Company
may be required to withhold with respect to such transactions.  Any such payment
must be made promptly when the amount of such obligation  becomes  determinable.
The  Administrator  may, in lieu of such cash  payment,  withhold that number of
shares sufficient to satisfy such withholding.

8.      ADJUSTMENT FOR CHANGES IN CAPITALIZATION.

        The  existence of  outstanding  Options  shall not affect the  Company's
right  to  effect  adjustments,  recapitalizations,  reorganizations,  or  other
changes in its or any other  corporation's  capital  structure or business,  any
merger or consolidation,  any issuance of bonds, debentures,  preferred or prior
preference stock ahead of or affecting the Stock, the dissolution or liquidation
of the  Company's or any other  corporation's  assets or business,  or any other
corporate  act,  whether  similar to the events  described  above or  otherwise.
Subject to Section 9, if the  outstanding  shares of the Stock are  increased or
decreased in number or changed into or exchanged for a different  number or kind
of  securities  of  the  Company  or  any  other  corporation  by  reason  of  a
recapitalization,  reclassification,  stock split,  combination of shares, stock
dividend,  or other event,  an appropriate  adjustment of the number and kind of
securities  with respect to which  Options may be granted  under this Plan,  the
number and kind of securities as to which outstanding  Options may be exercised,
and the exercise price at which  outstanding  Options may be exercised,  will be
made.

9.      DISSOLUTION, LIQUIDATION, OR MERGER.

        9.1  Company  Not  The  Survivor.  In  the  event  of a  dissolution  or
liquidation  of  the  Company,   a  merger,   consolidation,   combination,   or
reorganization in which the Company is not the surviving corporation,  or a sale
of substantially all of the assets of the Company,  any outstanding Option shall
become fully vested  immediately upon the Company's  public  announcement of any
one of the foregoing.  The Board of Directors shall  determine,  in its sole and
absolute  discretion, when the Company shall be deemed to survive  for  purposes

<PAGE>

of this  paragraph.  If the Optionee  does not exercise the entire Option within
ninety (90) days, the Administrator,  in its sole and absolute discretion,  may,
with respect to the unexercised portion of the Option:

               9.1.1 cancel the Option upon payment to the Optionee of an amount
equal to the  difference  between the closing price of the Stock  underlying the
Option   quoted  the  day  before   such   liquidation,   dissolution,   merger,
consolidation,  combination,  or  reorganization,  and the exercise price of the
Option; or

               9.1.2 assign the Option and all rights and  obligations  under it
to the successor  entity,  with all such rights and obligations being assumed by
the successor entity.

        9.2 Company Is The  Survivor.  In the event of a merger,  consolidation,
combination,   or   reorganization   in  which  the  Company  is  the  surviving
corporation,  the Board of Directors shall determine the appropriate  adjustment
of the number and kind of securities with respect to which  outstanding  Options
may be exercised,  and the exercise  price at which  outstanding  Options may be
exercised.  The Board of  Directors  shall  determine,  in its sole and absolute
discretion,  when the Company  shall be deemed to survive  for  purposes of this
Plan.

10.     CHANGE OF CONTROL.

        If there is a  "change  of  control"  in the  Company,  all  outstanding
Options shall fully vest immediately  upon the Company's public  announcement of
such a  change.  A  "change  of  control"  shall  mean an  event  involving  one
transaction or a related series of transactions, in which (i) the Company issues
securities equal to 25% or more of the Company's  issued and outstanding  voting

11.     SUSPENSION AND TERMINATION.

        In the event  the  Board or the  Administrator  reasonably  believes  an
Optionee has  committed  an act of  misconduct,  including,  but not limited to,
those specified  below,  the  Administrator  may suspend the Optionee's right to
exercise any Option granted hereunder  pending final  determination by the Board
or the Administrator.  If the Board or Administrator determines that an Optionee
has committed an act of misconduct,  including,  without  limitation,  an act of
embezzlement,  fraud,  breach of fiduciary duty, or deliberate  disregard of the
Company rules, or if an Optionee makes an unauthorized disclosure of any Company
trade secret or confidential  information,  engages in any conduct  constituting
unfair  competition,  induces any Company customer to breach a contract with the

proceeds from the sale of Company  assets upon  liquidation  until such Optionee
has  effectively  exercised  the Option and fully paid for such shares of Stock.
Subject to Sections 8 and 9, no adjustment  shall be made for dividends or other
rights  for which the  record  date is prior to the date  title to the shares of
Stock has been acquired by the Optionee.  The grant of an Option shall in no way
be construed so as to confer on any Optionee the rights to continued  employment
by the Company.

13.     TERMINATION; AMENDMENT.

        The Board may amend, suspend, or terminate this Plan at any time and for
any reason,  but no amendment,  suspension,  or termination  shall be made which
would impair the right of any person under any outstanding  Options without such
person's  consent  not  unreasonably  withheld.  Further,  any  amendment  which
materially increases the benefits accruing to participants under this Plan shall
be subject to the approval of the Company's shareholders.

14.     GOVERNING LAW.

        This  Plan and the  rights  of all  persons  under  this  Plan  shall be
construed in accordance with and under applicable  provisions of the laws of the
State of California.

Principal Amount: $3,000,000.00    Initial Rate: 8.500%    Date of Note: June 15, 1998

</TABLE>


PROMISE TO PAY. DIGITAL POWER  CORPORATION  ("Borrower")  promises to pay to SAN
JOSE NATIONAL BANK ("Lender"), or order, in lawful money of the United States of
America, the principal amount of Three Million & 00/100 Dollars  ($3,000,000.00)
or so  much  as  may be  outstanding,  together  with  interest  on  the  unpaid
outstanding principal balance of each advance. Interest shall be calculated from
the date of each advance until repayment of each advance.

PAYMENT.  Borrower will pay this loan on demand, or if no demand is made, in one
payment of all  outstanding  principal plus all accrued unpaid  interest on June
15, 1999.  In addition,  Borrower will pay regular  monthly  payments of accrued
unpaid interest  beginning July 15, 1998, and all subsequent  interest  payments
are due on the same day of each month after that.  The annual  interest rate for
this Note is computed on a 365/360 basis;  that is, by applying the ratio of the
annual  interest  rate over a year of 360 days,  multiplied  by the  outstanding
principal balance, multiplied by the actual number of days the principal balance
is outstanding.  Borrower will pay Lender at Lender's  address shown above or at
such other place as Lender may designate in writing.  Unless otherwise agreed or
required by applicable  law,  payments  will be applied first to accrued  unpaid
interest,  then to principal,  and any remaining amount to any unpaid collection
costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time  based on changes in the index  which is  Lender's  Prime Rate (the
"Index").  This is the rate Lender charges, or would charge, on 90-day unsecured
loans to the most creditworthy corporate customers.  This rate may or may not be
the lowest  rate  available  from  Lender at any given  time.  Lender  will tell
Borrower the current Index rate upon Borrower's  request.  Borrower  understands
that  Lender may make loans  based on other  rates as well.  The  interest  rate
change will not occur more often than each DAY.  The Index  currently is 8.500%.
The  interest  rate to be applied to the unpaid  principal  balance of this Note
will be at a rate equal to the Index,  resulting  in an initial  rate of 8.500%.
NOTICE:  Under no circumstances will the interest rate on this Note be more than
the maximum rate allowed by applicable law.

PREPAYMENT;  MINIMUM  INTEREST  CHARGE.  Borrower  agrees that all loan fees and
other  prepaid  finance  charges are earned fully as of the date of the loan and
will not be subject to refund  upon early  payment  (whether  voluntary  or as a
result of default), except as otherwise required by law. In any event, even upon
full prepayment of this Note, Borrower  understands that Lender is entitled to a
minimum interest charge of $100.00.  Other than Borrower's obligation to pay any
minimum  interest  charge,  Borrower may pay without penalty all or a portion of
the amount owed earlier than it is due. Early  payments will not,  unless agreed
to by Lender in writing,  relieve Borrower of Borrower's  obligation to continue
to make  payments  of accrued  unpaid  interest.  Rather,  they will  reduce the
principal balance due.

LATE  CHARGE.  If a payment  is 10 days or more late,  Borrower  will be charged
5.000% of the regularly scheduled payment or $25.00, whichever is greater.

DEFAULT.  Borrower  will be in  default  if any of the  following  happens:  (a)
Borrower  fails to make any payment when due.  (b)  Borrower  breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement  related to this Note, or in any other  agreement or loan Borrower
has with Lender. (c) Any representation or statement made or furnished to Lender
by Borrower  or on  Borrower's  behalf is false or  misleading  in any  material
respect  either  now or at the time  made or  furnished.  (d)  Borrower  becomes
insolvent, a receiver is appointed for any part of Borrower's property, Borrower
makes an assignment for the benefit of creditors, or any proceeding is commenced
either by Borrower or against  Borrower under any bankruptcy or insolvency laws.
(e) Any creditor tries to take any of Borrower's  property on or in which Lender
has a  lien  or  security  interest.  This  includes  a  garnishment  of  any of
Borrower's  accounts  with Lender.  (f) Any  guarantor  dies or any of the other
events described in this default section occurs with respect to any guarantor of
this  Note.  (g) A  material  adverse  change  occurs  in  Borrower's  financial
condition,  or Lender  believes  the prospect of payment or  performance  of the
indebtedness is impaired.

If any default,  other than a default in payment, is curable and if Borrower has
not been given a notice of a breach of the same  provision  of this Note  within
the preceding twelve (12) months,  it may be cured (and no event of default will
have occurred) if Borrower, after receiving written notice from Lender demanding
cure of such default:  (a) cures the default within fifteen (15) days; or (b) if
the cure requires more than fifteen (15) days, immediately initiates steps which
Lender deems in Lender's  sole  discretion  to be sufficient to cure the default
and  thereafter  continues  and  completes all  reasonable  and necessary  steps
sufficient to produce compliance as soon as reasonably practical.

<PAGE>


LENDER'S  RIGHTS.  Upon default,  Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest  immediately  due,  without
notice,  and then Borrower will pay that amount.  Upon Borrower's failure to pay
all amounts declared due pursuant to this section, including failure to pay upon
final maturity,  Lender, at its option, may also , if permitted under applicable
law, do one or both of the following: (a) increase the variable interest rate on
this Note to 5.000  percentage  points  over the  Index,  and (b) add any unpaid
accrued  interest to principal and such sum will bear interest  therefrom  until
paid at the rate provided in this Note  (including any increased  rate).  Lender
may hire or pay someone else to help collect this Note if Borrower does not pay.
Borrower also will pay Lender that amount. This includes,  subject to any limits
under  applicable  law,  Lender's  attorneys'  fees and Lender's  legal expenses
whether or not there is a lawsuit,  including attorneys' fees and legal expenses
for bankruptcy  proceedings (including efforts to modify or vacate any automatic
stay or  injunction),  appeals,  and any  anticipated  post-judgment  collection
services.  Borrower also will pay any court costs, in addition to all other sums
provided by law.  This Note has been  delivered to Lender and accepted by Lender
in the State of California. If there is a lawsuit, Borrower agrees upon Lender's
request to submit to the  jurisdiction of the courts of SANTA CLARA County,  the
State of  California.  Lender and  Borrower  hereby  waive the right to any jury
trial in any action,  proceeding,  or  counterclaim  brought by either Lender or
Borrower  against the other.  This Note shall be governed  by and  construed  in
accordance with the laws of the State of California.

DISHONORED  ITEM FEE.  Borrower  will pay a fee to Lender of $15.00 if  Borrower
makes a payment on Borrower's  loan and the check or  preauthorized  charge with
which Borrower pays is later dishonored.

RIGHT OF SETOFF.  Borrower grants to Lender a contractual  security interest in,
and hereby  assigns,  conveys,  delivers,  pledges,  and transfers to Lender all
Borrower's right, title and interest in and to, Borrower's  accounts with Lender
(whether checking, savings, or some other account), including without limitation
all accounts  held jointly with someone else and all accounts  Borrower may open
in the  future,  excluding  however  all IRA and Keogh  accounts,  and all trust
accounts for which the grant of a security  interest would be prohibited by law.
Borrower authorizes Lender, to the extent permitted by applicable law, to charge
or setoff all sums owing on this Note against any and all such accounts.

COLLATERAL.  This Note is secured by a SECURITY AGREEMENT DATED JANUARY 20, 1998
AND A UCC FILING DATED APRIL 28, 1994,  RECORDED AS INSTRUMENT  #94106664 ON MAY
27, 1994, WITH THE SECRETARY OF STATE IN SACRAMENTO.

LINE OF CREDIT.  This Note evidences a revolving line of credit.  Advances under
this Note may be requested orally by Borrower or by an authorized person. Lender
may, but need not,  require that all oral requests be confirmed in writing.  All
communications,  instructions, or directions by telephone or otherwise to Lender
are to be  directed to Lender's  office  shown  above.  The  following  party or
parties are authorized to request advances under the line of credit until Lender
receives  from  Borrower  at Lender's  address  shown  above  written  notice of
revocation  of their  authority:  ROBERT  SMITH,  PRESIDENT;  PHILIP  G.  SWANY,
SECRETARY; and JOSEPHINE JACKEWICZ, CONTROLLER. Borrower agrees to be liable for
all  sums  either:  (a)  advanced  in  accordance  with the  instructions  of an
authorized person or (b) credited to any of Borrower's accounts with Lender. The
unpaid  principal  balance  owing on this Note at any time may be  evidenced  by
endorsements  on this Note or by  Lender's  internal  records,  including  daily
computer  printouts.  Lender will have no obligation to advance funds under this
Note if: (a)  Borrower or any  guarantor  is in default  under the terms of this
Note or any agreement that Borrower or any guarantor has with Lender,  including
any agreement made in connection  with the signing of this Note; (b) Borrower or
any guarantor  ceases doing business or is insolvent;  (c) any guarantor  seeks,
claims or  otherwise  attempts  to limit,  modify  or  revoke  such  guarantor's
guarantee  of this  Note or any other  loan with  Lender;  or (d)  Borrower  has
applied  funds  provided  pursuant  to this Note for  purposes  other than those
authorized by Lender.

LETTER  AGREEMENT.  THIS NOTE IS SUBJECT TO, AND SHALL BE  GOVERNED  BY, ALL THE
TERMS AND CONDITIONS OF THE LETTER  AGREEMENT  DATED JUNE 11, 1996,  BETWEEN THE
BORROWER(S) AND SAN JOSE NATIONAL BANK,  WHICH LETTER  AGREEMENT IS INCORPORATED
HEREIN BY REFERENCE.

GENERAL  PROVISIONS.  This Note is payable on demand.  The inclusion of specific
default  provisions  or rights of Lender  shall not preclude  Lender's  right to
declare payment of this Note on its demand.  Lender may delay or forgo enforcing
any of its rights or remedies under this Note without losing them.  Borrower and
any other  person who signs,  guarantees  or endorses  this Note,  to the extent
allowed by law, waive any applicable statute of limitations, presentment, demand
for  payment,  protest and notice of  dishonor.  Upon any change in the terms of
this Note, and unless otherwise  expressly stated in writing, no party who signs
this Note, whether as maker, guarantor,  accommodation maker or endorser,  shall
be released  from  liability.  All such  parties  agree that Lender may renew or
extend  (repeatedly  and for any length of time) this loan, or release any party
or guarantor or collateral;  or impair, fail to realize upon or perfect Lender's
security interest in the collateral;  and take any other action deemed necessary
by Lender  without the  consent of or notice to anyone.  All such  parties  also
agree that  Lender  may modify  this loan  without  the  consent of or notice to
anyone other than the party with whom the modification is made.

PRIOR TO SIGNING THIS NOTE,  BORROWER READ AND  UNDERSTOOD ALL THE PROVISIONS OF
THIS NOTE,  INCLUDING THE VARIABLE INTEREST RATE PROVISIONS.  BORROWER AGREES TO
THE TERMS OF THE NOTE AND ACKNOWLEDGES RECEIPT OF A COMPLETED COPY OF THE NOTE.
