PART I


ITEM 1 - Business

Performance Technologies,  Incorporated designs, manufactures and markets a wide
variety of high reliability,  high performance  communications products that are
in one product segment and are grouped into five product  categories:  Wide Area
Networking products, LAN interface products, Mass Storage Interface products and
Inter-system   Connectivity  products.  Most  recently,  the  Company  has  been
developing its second generation family of high performance Network Switches for
Local  Area  Networks.   The  Company's   products  are  targeted   toward  high
performance,  mission  critical  applications  found in the  telecommunications,
financial services,  defense and public safety industries.  Applications include
network  interfaces  for  cellular  telephone  communications,  fiber optic data
communications products used aboard navy vessels, communications servers used in
air traffic control centers and enterprise Ethernet network switching products.

Since its inception in 1981, the Company has  consistently  produced  innovative
networking  solutions  for a wide  variety of computer  architectures  and has a
history of being able to adapt its products to a continually changing technology
driven  marketplace.  The Company has  focused  its  efforts on  providing  high
performance,   unique   application   solutions   where  hardware  and  software
reliability  are a key concern to the end user.  This  strategy  has enabled the
Company to increase both sales and income over the last five years.

As the Company  enters  1999,  management  is focusing  on the  development  and
delivery of new  products  for two distinct  communications  markets:  Wide Area
Networking communications and Local Area Network Switching.

Industry Overview

The need to collect,  store,  analyze and  distribute  information  in a secure,
timely and efficient  manner has become an integral part of the global  economy.
The  acceleration  of  developments  in both computer  technology  and telephony
technology  is  driving  the  convergence  of these  two areas  and  opening  up
substantial opportunities to supply infrastructure related products that address
these evolving technologies. Despite the recent rapid changes in the information
revolution,  there has been a clear distinction between the traditional computer
systems and the telephone  communications networks that connect to the computer.
Another  distinction  is between the network in which  computers  are  connected
within a business office,  Local Area Network (LAN) and the communications  link
to outside the business  office,  Wide Area Network  (WAN).  Recently,  computer
systems used for information processing and the telephone communication networks
are rapidly converging into one unified, but often  geographically  distributed,
architecture  where the  boundaries  between  the two  traditional  systems  are
blurred.  As  a  result,   there  have  been  many  new  hardware  and  software
opportunities   emerging  that  are  directly   related  to  implementing   this
convergence.  There is little doubt that computer  technology,  integrated  with
communication  technology,  is a convincing example of the "sum of the two being
greater than the whole."

Over the past decade, the computer systems used in many enterprises evolved from
large and expensive mainframes connected to numerous unintelligent terminals, to
a client/server  computing model. This contemporary model replaces the mainframe
with  one  or  more  powerful  servers  interconnected  to  intelligent  desktop
computers  through high bandwidth local area networks.  The growing  paradigm of
Client/Server  computer systems has been an ideal model to foster convergence of
data  communications and  telecommunications.  The integration of computers into
the  telecommunication  systems has already provided  enhanced  services such as
800/900 numbers,  call waiting,  caller ID, greater cellular  coverage,  reduced
cell and long  distance  rates,  and faster,  more  expansive  Internet  access.
Similarly,  data  communication  systems have  benefited from  integration  with
telecommunication  systems as individual  computers located throughout the world
are connected to vast communication  facilities with enormous information access
capability.

As a result of this rapid convergence, the market opportunity for networking and
communication  products is rapidly  expanding.  According  to a recent  industry
study, the Ethernet LAN switching market is forecasted to reach over $15 billion
in 1999 and has  been  growing  at over 35% per  year.  The  Wide  Area  Network
communication  arena is expected to grow from $750  million in 1998 to over $4.0
billion by the year 2003. These impressive growth estimates, combined with other
market trends, are expected to cause the computer networking  equipment industry
to  experience  a  substantial  increase  in  demand  as  they  enter  the  next
millennium.  The next rapidly  growing  phase of this  convergence  is likely to
center  around the use of data  communication  networks to also carry  real-time
voice and video  traffic,  in many  instances  bypassing the older voice centric
telecommunications  infrastructure.  The Company's WAN  Communications and Local
Area  Network  Switching  products  address  product  segments  of these  larger
markets.

Strategy

The Company's  strategies are directed at ensuring its products and services are
correctly  positioned to take advantage of the many  opportunities  presented by
the changing  technologies  and  convergence  phenomena.  Major  elements of the
Company's operational strategy include:

Focus on High Performance Mission Critical  Solutions.  The Company continues to
focus its development  efforts on addressing specific needs for high performance
Wide Area and Local Area  Networking.  The  Company's  products  provide  unique
mission  critical  solutions  where  reliability and performance are the primary
concerns  of the  user.  Typical  applications  that  demonstrate  this  mission
critical focus include  network  interfaces for cellular  telephone  transmitter
sites,  fault-tolerant Fiber Digital Data Interface (FDDI) adapter products used
aboard Navy vessels and terrestrial military vehicles,  network adapters used in
the control and billing systems of traditional  telecommunications  networks and
communications  servers  used in both rail and air traffic  control.  To a large
degree, the Company has avoided networking and communication products that would
be  sold  into  the  commodity  desktop  office  or  home   environment,   often
characterized by low price, large volumes and fierce competition.

Exploit  Technological  Competencies.  Since  its  inception,  the  Company  has
pioneered many innovations in networking and computer technologies including the
VME64  industry  standard,  proprietary  ASICs  and  innovative  "hot  swap" and
"failover"  techniques  to  enhance  equipment   availability  and  reliability.
Building on a strong base of technological competency has allowed the Company to
develop  innovative  products that improve data  communications  performance and
reliability.  Management  intends to continue to leverage  its  competencies  to
position  the Company as a  technological  leader in high  performance  and high
availability WAN and LAN hardware and software products.

Continue to Develop Advanced  Networking  Products.  The Company  recognizes the
need to  continually  upgrade the  performance  of its existing  products and to
develop new  products  which  address the changing  requirements  of WAN and LAN
applications.  Over the past 12 months,  the Company has introduced a variety of
WAN and LAN products  designed for the PCIBus and the new  "industrialized"  PCI
standard   called   CompactPCI   (cPCI)   which   is  being   embraced   by  the
telecommunications and defense industries for next generation equipment. Several
of these products have been early and unique  entrants into the growth  oriented
PCIBus and cPCI arena aimed at supporting complex  communications  protocols and
network  requirements  associated with such  applications as air traffic control
radar systems, Signaling System #7 (SS7) network control systems and channelized
T1/E1 high speed network  interfaces.  These new products have been  responsible
for a variety of potentially significant OEM and partnering  relationships.  The
Company has also  developed a family of switching  products  for  Ethernet  LANs
directed at specific applications requiring high availability. Delivery of these
LAN products  began in 1998 with a unique fault  tolerant model due for shipment
in 1999.

Expand  International  Markets.  The data  communication  markets  served by the
Company are international in scope. Global demand for network products is driven
by the  increasing  need of all societies to be able to  successfully  implement
advanced  networking  and  communications  infrastructures.   Outside  of  North
America,  the Company  markets its products  primarily in Western Europe and the
Asia  Pacific.  In an ongoing  effort to  increase  international  revenue,  the
Company has been investing in the expansion of its marketing,  sales and support
operations in these specific  geographic areas. In 1998, the Company reorganized
its direct sales and support in the European  Economic  Community  (E.E.C).  The
Company now operates a sales and support office in the United Kingdom  providing
coverage  to the Western  European  markets.  In addition to the direct  Company
presence in the E.E.C., the Company continues to employ a variety of third party
organizations to assist in establishing  both OEM and  distribution  accounts in
Europe and the Asia Pacific regions.  In 1998,  international  revenue increased
substantially  over the previous year and represented 23% of annual sales.  This
growth was directly  attributable  to several  successful OEM  relationships  in
Europe.  As corporate  revenue grows in the Pacific Asia area, the Company would
anticipate opening a direct sales and service center in this area of the world.

                                       2

Leverage  Software   Expertise.   The  Company  has  a  growing   competency  in
communications, networking and high availability software expertise. The Company
has significantly expanded its ability for offering communication  protocols for
Wide Area  Networks by combining  its east and west coast  software  engineering
organizations. In addition, the Company has invested substantially in developing
fault tolerant and hardened  software  implementations  used in both WAN and LAN
products.  Management  believes  focusing  on  increasing  software  content  in
products  emphasizing high availability and reliability features is an important
element of the Company's future product strategy.

Capitalize  on Internal  Manufacturing  Expertise.  Unlike many of its  industry
competitors,   the  Company  does  not  rely  upon  third  party   manufacturing
subcontractors for assembly, test and quality control of its products.  Instead,
the Company operates a  state-of-the-art  manufacturing  facility that gives the
Company the  flexibility  to meet  customer  requirements,  produce high quality
products  and  make  timely  shipments.  The  Company's  manufacturing  facility
operates under an integrated MRP system that significantly reduces lead-time and
inventory investment and facilitates effective demand forecasting. This in-house
manufacturing  capability  provides  the  Company  with  the  means  to  quickly
manufacture new products without the delays normally  associated with the use of
manufacturing  subcontractors.  During 1998,  additional surface mount equipment
was installed to assure continued high quality assembly with sufficient capacity
to meet expected  delivery  requirements  for the Company's  expanding  customer
base.  The  Company's  manufacturing  process  is  certified  under the ISO 9002
quality program.

Products

The  Company's  products  include  a  wide  variety  of   fault-tolerant,   high
performance  solutions  for  WAN  communications,   LAN  connectivity  and  mass
storage/retrieval applications. The Company historically has addressed the needs
of the  client/server  computing  environment  with a  family  of  hardware  and
software  products which operate on a number of open standards and allow ease of
use with a variety of popular high performance computer platforms. The Company's
products   have   traditionally   been   grouped  into  five   categories:   WAN
Communications  products,  LAN  Interface  Adapter  products,   Network  Systems
products,   Mass  Storage  Interface  products  and  Inter-system   Connectivity
products.  The Company has also been developing its second generation of network
switches for Local Area  Networks.  As the Company  enters 1999,  management  is
focusing on the  development  and  delivery  of new  products  for two  distinct
communications  markets:  Wide Area  Networking  communications  and Local  Area
Network Switching.

WAN Communications  Products. The Company's WAN Communications  products provide
customers with hardware and software  solutions  which support a variety of open
system platforms. These open systems include VMEbus, SBus, PCIBus, CompactPCIbus
(cPCI) and PMCbus. The Company offers software support for its products across a
variety of commonly used operating systems including Microsoft's WindowsNTJ, Sun
Microsystems'  SolarisJ,  Wind  River's  VxWorks,  and QNX.  In  addition to the
advanced  hardware network interface  products,  the Company offers an extensive
suite of advanced  communication  software such as X.25, Frame Relay, High Level
Data Link Control (HDLC)  variants,  Signaling System #7 (SS7), and a variety of
protocols to facilitate high and low speed  communications.  The  communications
software  content is further expanded by the Company's  channelized  support for
T1/E1  data  rates and  software  protocol  tool kits for  specialized  customer
development.  The growth in the Wide Area Networking (WAN) communications market
is being driven by the expansion of the Internet,  cellular  communications  and
the convergence  occurring between data  communications and  telecommunications.
WAN Communications product customers include Lucent Technologies, Compaq/Digital
Equipment Corporation, QualComm Inc., Alcatel Inc., Motorola Corporation and ADC
NewNet.  Product  applications  cover a variety  of uses  including:  High speed
Internet  connections for server products,  T1/E1 products used for SS7 products
and communications for rail and subway signaling.

During 1998, the Company released three new Wide Area Network interface adapters
for the cPCIbus  architecture.  These products were designed  specifically  with
features  that  are  required  in  advanced   telecommunications   applications,
including  the  necessary  capability  for "hot  swap  replacement."  Management
believes  that  the  Company's  cPCI  products  are some of the  first  products
available to cPCI users for high speed WAN communications.  All of the Company's
WAN  Communications  products are designed  for  applications  that require high
performance  and  high  speed  communications   capability.   To  support  these
applications,  the Company's  products are  "intelligent,"  containing their own
microprocessors  and memory.  This  architecture  allows these network interface
products  to perform  many of the  lower-level  communications  tasks that would
typically be performed by the host platform,  greatly  improving  overall system
performance and capability. During 1998, the Company also expanded its family of
WAN software protocol products with emphasis on enhancing speed and reliability.
WAN product sales  represented 58% of total sales for 1998,  compared to 47% for
1997 and has been the highest  growth product area for the Company over the past
three years .

Local  Area  Network  Switching.  The  Company  has  been  developing  a  second
generation family of high performance 100Mbit/Gigabit Network Switches for Local
Area Networks which offer a variety of unique technical  features.  During 1998,
the Company  completed  development of its new Nebula (TM) 4000 workgroup switch
and its new Nebula 6000 high density departmental switch. The centerpiece of the
Company's  Local Area Network switch  strategy is the Nebula 8000 Fault Tolerant
Backbone  Switch.  This 100/1000  Ethernet switch is the first network switch to
offer true fault tolerance at an affordable  price.  The Nebula 8000's redundant
switch fabric has been  engineered for maximum  availability  and its innovative
design ensures that no single point of failure will shutdown a network.

The market  demands  for fault  tolerant  computing  and  networking  are rising
rapidly.  Server  manufacturers  including  Compaq  Computer  Corp.  and  Tandem
Computers have developed server clusters to meet their customers' fault tolerant
server  requirements.  Networking  companies,  including  Novell,  are  actively
promoting and selling  networking  solutions for mission critical  applications.
Management  believes that  deployment of its fault tolerant  technologies in the
new Nebula 8000 Backbone Switch differentiates PTI from the other vendors in the
network switching marketplace. This new product is being positioned for Ethernet
based  business  and  mission   critical   applications  in  enterprises   where
"round-the-clock"  operations demand highly resilient  network  infrastructures.
Prospective  customers in the banking,  brokerage,  medical  imaging and defense
industries are expressing serious interest in this product.

As of March 1999, the Nebula 8000 was operating in a number of early beta sites,
including the Company's communications network.  Additional beta sites have been
selected and units are expected to be installed in these  locations in April and
May. Shipments to customers are expected to commence in the second quarter 1999.

LAN Interface  Adapter  Products.  The Company's LAN Interface  Adapter products
consist primarily of products often referred to as Network Interface Controllers
(NICs) for a variety of LANs and computer platforms.  These products represented
20% of sales in 1998 and 1997. These products  currently  operate on the PCIBus,
SBus and VMEbus computer  platforms and include  connections for a popular range
of Ethernet  and FDDI  standards  and a unique FDDI  concentrator  product  that
operates on the VMEbus. Applications for the Company's Ethernet and FDDI network
adapter products include a convenient  interface between computer  platforms and
LANs used in commercial, educational or industrial organizations and a shipboard
FDDI  LAN  used  by  the  U.S.  Department  of  Defense  to  integrate  tactical
workstations  onboard Navy vessels. All of these NICs permit easy integration of
SBus,  PCIBus or VMEbus  computer  systems to an FDDI or Ethernet  LAN. The FDDI
adapters  support the  Company's  alternate  path FDDI  topology,  ensuring  the
highest available levels of resiliency and data integrity for fault-tolerant and
mission critical  markets.  The Company actively supports software supplied with
its newest  PCI-based  FDDI  adapters to be compatible  with computer  platforms
utilizing both the Sun Microsystems' Solaris and WindowsNT operating systems. It
is  management's  belief that the FDDI  technology  as a LAN  technology  is not
growing  and the  Company's  FDDI  products  are in the  harvest  phase of their
product life cycle and a decline can be predicted over the next 18-24 months.

Network Systems  Products.  The Company's  Network Systems  products  consist of
system level  equipment  used in the  construction  and  deployment  of computer
networks.  These  products  represented  6% of sales in 1998,  compared to 9% in
1997. The engineering  staff supporting this product group was reassigned at the
beginning of 1998 to develop software for WAN Communications products.
Traditionally this group has included:

                                       4

Communications  Servers.  Communications  servers  are  multipurpose  LAN-to-WAN
bridging  systems  supported  by  software  from the  Company's  San Diego based
communication protocol engineering center. The products in this category include
a low cost, limited server solution for installations  requiring from one to six
WAN connections and up to two Ethernet LAN  connections.  Using unique software,
the  communications  servers can be  configured to provide a variety of protocol
packages  and  supporting   protocols  including   bisynchronous,   asynchronous
communications  financial  market feeds and radar receivers.  The  communication
server  products from the Company can be found in data  collection  applications
including  NASA's  deep  space  network,  in air  traffic  control  centers  for
retrieving  radar data from  remote  radar  antenna  sites and in the US Weather
Service  infrastructure  for  retrieving  weather  satellite  and radar  images.
Management  believes this product  offering  will see continued  growth in 1999.
Since  communications  servers are directly aligned with the Company's Wide Area
Network  communications  products,  these  products  will  be  reported  in that
grouping in 1999.

Communications   Subsystems.   The  Company's   "front-end"  I/O  communications
subsystem  product supports  multiple disk storage  controllers or communication
interface modules.  This product was co-developed by the Company and a large OEM
customer and is used as a  communications  nexus for high powered  workstations.
Since this is a very specialized  product offering with a limited customer base,
management expects revenue from this product to decline in 1999.

Mass Storage Interface  Products.  The Company's Mass Storage Interface products
consist of adapters and  software  that connect  various  external  disk storage
systems,  such as  Redundant  Array of  Inexpensive  Disks  (RAIDs) to  computer
servers using the SCSI, UltraSCSI and Fibre Channel  technologies.  During 1998,
the Company  introduced new products  designed to operate on the PCIBus standard
using Fibre  Channel.  As the  technologies  have  changed in this  market,  the
products have increasingly become "commoditized"  thereby reducing the Company's
ability to achieve  value-added  pricing.  While the Company is  supporting  the
current  customer base in their transition from older  technologies,  it expects
revenue to decline in 1999 and beyond.  This  product  group  represented  9% of
sales in 1998, compared to 14% in 1997.

Inter-system  Connectivity  Products.  The Company's  Inter-system  Connectivity
products permit dissimilar  computer  standards to be connected.  These products
are typically used by OEMs and systems  integrators for custom  applications and
allow  their  customer's  to maintain  their  investment  in existing  installed
equipment.  These products  represented 7% of sales in 1998,  compared to 10% in
1997.  Management does not believe these products are strategic to the Company's
future growth and is not investing in this business segment. Management believes
there will be further declines in this revenue during 1999.

Sales, Marketing and Distribution

The Company  markets its  products  worldwide  to a broad  spectrum of customers
through  various  channels  including  OEMs,  VARs,   distributors  and  systems
integrators.  Greater than 85% of the Company's North American  business is sold
through the Company's  direct sales force to OEMs and systems  integrators.  The
remainder is sold to end users through distributors and VARs.

Due to the  technical  nature  of the  Company's  products  sold to OEMs,  it is
essential  that the  Company's  salespeople  are  technically  oriented  and are
knowledgeable in the network and communications fields.

In North America,  the Company operates four direct sales offices located in San
Diego  California,  Rochester New York,  Old Saybrook  Connecticut,  and Houston
Texas.  The Company  also  maintains  its European  sales and support  office in
London.  Currently, 22 sales, marketing and support personnel sell the Company's
products.  In addition,  independent  sales  representatives  covering  selected
geographic  areas, and distributors or integrators  handling  selected  products
supplement the Company's direct sales team on a worldwide basis.

The Company also sells products,  including mass storage interface  products and
certain LAN interface products,  to distributors.  In addition,  a small, highly
focused group of distributors,  VARs and integrators are involved in selling the
Company's network and fault tolerant switching  products.  The "vertical market"
business  focus of these  VARs  and  integrators  is  targeted  toward  specific
applications  which are considered  mission  critical such as "7 day by 24 hour"
operations in the following industries:  airline, trading floor applications for
the financial industry and medical systems in hospitals.  Distributors, VARs and
integrators who sell the Company's  products are managed by the Company's direct
sales force.  Several marketing strategies are used to support these third party
organizations  including advertising in trade publications,  sponsoring customer
training  sessions and  participating  in trade shows  throughout North America,
Western Europe and the Pacific Rim.

                                       5

OEM customers  typically  provide the Company with a rolling forecast for orders
placed  two to three  months in  advance  of  shipment.  VARs,  integrators  and
distributors typically provide the Company with orders placed 30 days in advance
of shipment.  Sales of the Company's  products to OEM customers are subject to a
number of factors outside the Company's control, including pricing, availability
and acceptance of these products by the OEM's customers and potential customers.

The Company executes various ongoing  marketing  strategies  designed to attract
new OEM customers and to stimulate additional purchases from existing customers.
These  strategies  include  direct mail  campaigns and  catalogue  distribution,
direct  telemarketing,   special  pricing  programs,   active  participation  in
technical  standards groups,  participation in national and regional trade shows
and selected  trade press  advertisements  and technical  articles and an active
campaign to direct potential customers to the corporate web site.

International  sales  represented  23% of the  Company's  net  sales in 1998 (as
compared  to  10%  and  11%  for  1997  and  1996,  respectively).   While  1998
international revenue represents a substantial increase over previous years, the
Company continues to believe that the international  markets represent important
untapped opportunities for its products. Management believes that it can develop
expanded sales channels and marketing alliances with respect to new and existing
international  markets  and  is  actively  pursuing  these  relationships.   The
Company's   products  are  currently  sold  by  approximately  25  international
distributors  throughout  the major  industrialized  countries in Europe and the
Asia  Pacific.  The Company also  operates a sales and  marketing  office in the
United Kingdom to better support its Western  European  customers.  In addition,
the Company  continues to engage two  international  marketing  organizations to
assist in more aggressive  development of the Pacific Rim and other  territories
across all of its product offerings.  Use of these third party  organizations is
primarily viewed as an interim step that will to lead to additional direct sales
offices in Europe and the  Pacific  Rim,  assuming  the Asian  economic  climate
improves.  International  sales are  subject  to  import  and  export  controls,
transportation  delays and  interruptions,  foreign currency exchange rates, and
foreign governmental regulations.  All payments for shipments outside the United
States are made in U.S. dollars.

Customers

The Company has over 300 active customers worldwide, including major OEMs, Value
Added Resellers,  systems integrators,  and educational/research  organizations.
Many of the Company's  major  customers are Fortune 500 companies.  In 1998, the
largest single customer  represented 13% of sales (Compaq Computer  Corp.),  and
the top five customers accounted for 39% of 1998 revenue.

Generally, the Company's customers can be grouped into two categories. The first
category includes customers that are technically oriented and assemble a product
or system for a specific end use, using components and subassemblies supplied by
vendors such as the Company.  These  products or systems are  typically  sold on
either a repetitive  basis or on a lower volume,  purpose-built  basis.  End use
equipment  or  systems  sold by OEMs on a  repetitive  basis  incorporating  the
Company's products often include  applications such as sophisticated  enterprise
servers  with  high  speed  WAN  interconnections  to the  Internet  or  private
communication  facilitates  specialized  Signaling  System  #7  server  clusters
installed  worldwide by many  telecommunications  organizations  for 800 and 900
number implementations. Examples of lower volume purpose-built end use equipment
incorporating  the Company's  products  include FDDI networks used by the United
States Navy for shipboard use, communication servers for deep space network used
by space research  organizations  and data  collection  network  systems for air
traffic control and radar installations.

The second category are customers  requiring products to be self-installing  and
require limited knowledge of the products'  internal  operation.  These products
are  often  referred  to as  "plug  n' play" or  "shrink  wrapped,"  implying  a
readiness  to  simply  install  the end  application  without  the  need to have
extensive  technical  knowledge.  The  Company's  products  that fit  into  this
category are the SBus and PCIBus Mass Storage Interface, the SBus and PCIBus LAN
products  (Ethernet  and  FDDI  Niches)  and  selected  WAN  Interface  products
operating on the SBus and PCIBus standards.

Backlog

At March 7, 1999, the backlog of scheduled orders was $7.7 million,  compared to
$4.7 million at March 2, 1998.  Although  orders are subject to  cancellation in
the normal course of business,  historically  the Company has filled most of its
firm orders. (See Management's  Discussion & Analysis included elsewhere in this
report).

Seasonality

The  Company's  business is  generally  not  considered  to have large  seasonal
swings,  but some of the business  (primarily LAN Interface products and Network
Systems products) is project-related, driven by customer demand, which can cause
quarterly fluctuations in revenues.

Environmental Matters

The Company does not believe that compliance  with federal,  state or local laws
or regulations  relating to the protection of the  environment  has any material
effect on its capital expenditures, earnings or competitive position.

Competition

The market for communications, networking and mass storage interface products is
intensely  competitive and  characterized  by rapid  technological  innovations,
resulting   in   new   product    introductions   and   frequent   advances   in
price/performance  ratios.  Competitive factors in this industry include product
performance and functionality, product quality and reliability, customer service
and support,  marketing capability,  corporate reputation and brand recognition,
and increases in relative  price/performance  ratios. In the WAN  communications
market, the Company's products compete with products from SBE Incorporated, Adax
Incorporated and Digi  International  Incorporated.  In the emerging cPCI arena,
the Company's competition is less well-defined,  although early entrants include
Force Computers, a division of Solectron Corporation, and SBS Technologies, Inc.
In  the  LAN  Interface  product  market,  the  Company  competes  with  Network
Peripherals Inc., Osicom Technologies,  Incorporated and Interphase Corporation.
In the Mass Storage  Interface  product market,  the Company  competes with such
companies as Interphase Corporation,  MacroLink Incorporated,  Sun Microsystems,
Emulex Corporation, Qlogic Corporation and Adpatec, Incorporated.

In the Local Area Network Switching  market,  the Company is focusing on a niche
application,  fault  tolerance.  However,  many of the  companies in this market
focus on broad  applications  products  and have greater  technical  and capital
resources, more marketing experience, larger research and development staffs and
better production facilities than the Company. In recent years the local network
switching   market  has  become   increasingly   concentrated  as  a  result  of
consolidations in the industry. Cisco Systems Inc., the industry routing leader,
has acquired companies that have historically  competed with the Company.  These
consolidations are likely to permit Cisco and other of the Company's competitors
such as Cabletron  Systems,  3Com Corp and Xylan Corp,  to devote  significantly
greater resources to the development and marketing of new competitive networking
products  and  the   marketing  of  existing   products   through  their  larger
distribution  networks to their larger  installed  customer  bases.  The Company
expects that  competition  will increase  substantially as a result of these and
other industry  consolidations,  as well as the emergence of new competitors and
new  technologies.  Increased  competition  could  result  in price  reductions,
reduced  margins and loss of market  share,  all of which would  materially  and
adversely  affect  the  Company's  business,  operating  results  and  financial
condition.

Research and Development

The Company's research and development expenses,  plus costs attributable to the
development  of  software,  for  1998,  1997 and 1996  were  approximately  $4.2
million,  $3.7 million and $3.0 million,  respectively.  These expenses  consist
primarily of employee  costs and material  consumed in developing  and designing
new products.  To a lesser degree,  there have been limited  expenses devoted to
technology acquisition, software license/tools and contract product development.

                                       7
<PAGE>

The Company  has, as a result of prior  research and  development  expenditures,
developed  significant core  competencies  applicable to high speed  fiber-optic
local area networking,  wide area networking,  and fault tolerant switching. The
Company expects that research and development  funding will continue to increase
significantly in 1999. This funding will be directed at further leveraging these
competencies  and carrying out  additional  product  development in the areas of
communications and network  switching.  In carrying out this focused effort, the
Company has increased its internal  capability to design and implement ASICs and
has invested  substantially in integrating and expanding its  communication  and
networking  software  competency.   These  competencies  will  be  an  important
cornerstone for continued  future  enhancements of WAN network products and high
performance  fault  tolerant  switching  architectures  to support the  emerging
Gigabit Ethernet LAN technology.

Proprietary Technology

The Company's  success  depends upon the Company's  proprietary  technology.  To
date, the Company has relied  principally  upon  trademark,  copyright and trade
secret laws to protect its proprietary technology.  The Company generally enters
into confidentiality or license agreements with its distributors,  customers and
potential  customers and limits access to and distribution of the source code to
its software and other  proprietary  information.  The  Company's  employees are
subject  to the  Company's  employment  policy  regarding  confidentiality.  The
Company's  software  products and  accessories  are provided to customers  under
license,  generally in the form of object code,  which provides a high degree of
confidentiality  with respect to the  intellectual  property value.  Much of the
Company's proprietary  technology is found in the Company's source code which is
embedded in silicon chips,  making it extremely  difficult to  misappropriate or
reverse engineer.  Such methods may not afford complete protection and there can
be no assurance that the  confidentiality  agreements  will not be breached,  or
that such agreements will be enforceable, or that the Company will have adequate
remedies for any breach,  or that the Company's trade secrets will not otherwise
become  known  to  or   independently   developed  by  competitors.   If  patent
applications  are filed by the Company in the future,  there can be no assurance
that any patents can be granted, or that, if granted, such patents would provide
the Company with meaningful  protection from competition.  The Company currently
has  an  outstanding  patent  application  pending  for  a  variety  of  aspects
associated  with its  fault  tolerant  network  switching  products.  Management
expects the U.S. Patent office to render a ruling on this application in 1999.

There can be no  assurance  that  third  parties  will not  assert  intellectual
property infringement claims against the Company.  Although no written claims or
litigation  relating  to any such  matters  are  currently  pending  against the
Company,  the Company has not  conducted  any searches or obtained an opinion of
counsel with respect to its  proprietary  rights.  Accordingly,  there can be no
assurance  that no claims will be  initiated,  that the Company would prevail in
any such  litigation  seeking  damages or an injunction  against the sale of the
Company's  products,  or if necessary,  that the Company would be able to obtain
any necessary  licenses on reasonable terms or at all. Any such litigation could
be  protracted  and  costly  and could  have a  material  adverse  affect on the
Company's results of operations regardless of the outcome of the litigation.

Suppliers

Certain  components  used in the  Company's  products,  such as specific  single
source  microprocessors,  custom ASICs,  FDDI  interface  components  and highly
integrated PCIBus and VMEbus interface components,  are only currently available
to the Company from limited sources.  Technology oriented markets are especially
subject  to rapid  change.  As a  result,  over  the  course  of short  periods,
components  utilized by the Company face  ongoing "End of Life" risks.  To date,
the Company has generally been able to obtain adequate supplies of components or
has redesigned specific products when adequate components are not available. The
Company obtains components on a purchase order basis and does not generally have
long-term contracts with any of these suppliers.  In addition,  shortages of raw
materials could negatively  affect the Company's  ability to meet its production
obligations  and result in increased  prices to the Company for affected  parts.
The  Company's  inability  in the  future  to obtain  sufficient  limited-source
components, or to develop alternative sources, could result in delays in product
introductions  or shipments,  premature  End of Life of the Company's  products,
and/or increased component prices could negatively affect gross margins,  any of
which  could  have a  material  adverse  effect  on  the  Company's  results  of
operations.  The  Company  would  also be  negatively  affected  if it does  not
maintain adequate capital resources to fund component purchases.

                                       8
<PAGE>

Manufacturing

The Company  maintains a  state-of-the-art  product  assembly and  manufacturing
facility in Rochester,  New York. This facility operates under an integrated MRP
system that  significantly  reduces  lead-time  and  inventory  investments  and
facilitates  effective demand  forecast.  In December 1997, the Company received
ISO 9002  certification of its manufacturing  facilities and quality  management
systems.  By  maintaining  an  in-house  manufacturing  capability,   management
believes that the Company has, to a certain  extent,  insulated  itself from the
risks inherent in dealing with independent  subcontractors.  These risks include
timing  delays  that often  result  when  subcontractors  are unable to meet the
manufacturing requirements of their customers. In addition, through its in-house
manufacturing  capability,  the Company is able to oversee  directly its quality
control process and the timeliness of product delivery.  The Company has limited
alternative  capabilities  through  third  parties,  however,  to  perform  such
manufacturing  activities.  In the event of an interruption of production at its
manufacturing  facility,  the Company's  ability to deliver products in a timely
fashion would be compromised,  which would have a material adverse effect on the
Company's results of operations.

Employees

As of March 1, 1999, the Company had 140 full-time  employees,  10 part time and
contract employees and 3 Engineering Cooperative employees.  Management believes
its  relations  with its employees  are good.  The  Company's  employees are not
subject to collective bargaining agreements.

 These employees work in the following areas:

                  Research and Development                    53
                  Marketing and Sales                         22
                  Manufacturing                               59
                  General and Administrative                  19

Competition  for technical  personnel in the Company's  marketplace  is intense.
Management believes that the Company's future success will depend on its ability
to continue to attract and retain qualified personnel.

Risk Factors

Technological Change and New Product Introductions. The market for the Company's
products  is   characterized   by  rapid   technological   change  and  frequent
introduction  of  products  based on new  technologies.  As these  products  are
introduced,  the  standards of the industry  change.  Additionally,  the overall
computer networking industry is volatile as the effects of new technologies, new
standards,  new  products  and short life  cycles  contribute  to changes in the
industry and the  performance  of industry  participants.  The Company's  future
revenue  will  depend upon the  Company's  ability to  anticipate  technological
change and to develop  and  introduce  enhanced  products of its own on a timely
basis that meet or exceed new  industry  standards.  New  product  introductions
could  contribute to quarterly  fluctuations in operating  results as orders for
new  products  commence  and orders for  existing  products  decline.  Moreover,
significant  delays can occur between a product's  introduction and commencement
of volume production. The inability to develop and manufacture new products in a
timely manner, the existence of reliability, quality or availability problems in
the  products  or their  component  parts,  or the  failure  to  achieve  market
acceptance  would have a material  adverse  effect on the Company's  revenue and
operating results.

Competition. The computer communications,  networking and mass storage interface
business is  extremely  competitive  and the Company  faces  competition  from a
number of established and emerging computer  communications and inter-networking
device companies.  Many of the Company's principal  competitors have established
brand name  recognition  and market  positions  and have  substantially  greater
experience and financial resources to spend for promotion, advertising, research
and product  development  than the Company.  Several of these  competitors  have
recently  introduced or announced their  intentions to introduce new competitive
products.  In addition,  as the Company broadens its product  offerings,  it may
face competition from new competitors.  Companies in related markets could offer
products with functionality similar or superior to that offered by the Company's
products.  Increased  competition  could  result  in price  reductions,  reduced
margins and loss of market share,  all of which would  materially  and adversely
affect the  Company's  revenue and operating  results.  Several of the Company's
competitors  have recently been acquired by major  networking  companies.  These
acquisitions   are  likely  to  permit  the  Company's   competition  to  devote
significantly  greater  resources  to  the  development  and  marketing  of  new
competitive products and the marketing of existing competitive products to their
larger  installed  bases.  The Company  expects that  competition  will increase
substantially  as a result  of  these  and  other  industry  consolidations  and
alliances,  as  well  as the  emergence  of  new  competitors.  There  can be no
assurance  that  the  Company  will be able to  compete  successfully  with  its
existing or new competitors or that  competitive  pressures faced by the Company
will not have a material  adverse effect on the Company's  revenue and operating
results.

                                       9
<PAGE>

Dependence  on Key  Customers.  There  can be no  assurance  that the  Company's
principal  customers  will  continue  to purchase  products  from the Company at
current levels.  Customers typically do not enter into long-term volume purchase
contracts  with the Company and customers have certain rights to extend or delay
the shipment of their  orders.  The loss of one or more of the  Company's  major
customers,  and the  reduction,  delay or  cancellation  of orders or a delay in
shipment  of the  Company's  products  to such  customers  would have a material
adverse effect on the Company's revenue and operating results. (See Management's
Discussion & Analysis included elsewhere in this report).

Potential Fluctuations in Annual and Quarterly Results. The Company's annual and
quarterly  operating results may in the future vary  significantly  depending on
factors  such as the timing and  shipment  of  significant  orders,  new product
introductions by the Company and its competitors,  market  acceptance of new and
enhanced versions of the Company's products,  changes in pricing policies by the
Company and its competitors,  the mix of distribution channels through which the
Company's products are sold,  inability to obtain sufficient supplies of sole or
limited  source  components  for the  Company's  products,  seasonal and general
economic  conditions.  The Company's  expense levels are based,  in part, on the
Company's  expectations as to future revenue. Since a substantial portion of the
Company's  revenue in each quarter result from orders shipped in the final month
of that quarter,  revenue levels are extremely  difficult to predict. If revenue
levels are below  expectations,  revenue and operating results will be adversely
affected.  Net income  would be  disproportionately  affected by a reduction  in
revenue  because only a small portion of the Company's net expenses  varies with
its revenue.  (See Management's  Discussion and Analysis  included  elsewhere in
this report).

Dependence on Third Party Component  Suppliers.  Certain  components used in the
Company's products are currently  available to the Company from one or a limited
number of sources.  Although to date,  the  Company has  generally  been able to
obtain  adequate  supplies of these  components,  there can be no assurance that
future supplies will be adequate for the Company's needs or will be available on
prices and terms  acceptable  to the  Company.  The  Company's  inability in the
future to obtain sufficient limited-source components, or to develop alternative
sources,  could  result in delays in  product  introduction  or  shipments,  and
increased  component prices could negatively affect the Company's gross margins,
either of which will have a material adverse effect on the Company's revenue and
operating results.

Dependence  on  Internal  Manufacturing.  In order to avoid  relying  on outside
contract  manufacturers,  the Company  manufactures  all of its  products at its
Rochester,   New  York   facility.   The  Company  does  not  have   alternative
manufacturing  capabilities,  either  internally  or through third  parties,  to
perform those manufacturing functions. Even if the Company were able to identify
alternative third-party contract  manufacturers,  there can be no assurance that
the  Company  would be able to retain  their  services  on terms and  conditions
acceptable to the Company.  In the event of an interruption  in production,  the
Company may not be able to deliver products on a timely basis, which will have a
material adverse effect on the Company's revenue and operating results. Although
the Company currently has business interruption  insurance, no assurances can be
given that such insurance will adequately cover the Company's lost business as a
result of such an interruption.

Dependence on Proprietary  Technology.  The Company's  success  depends upon the
Company's proprietary technologies.  To date, the Company has relied principally
upon  trademark,  copyright  and trade  secret laws to protect  its  proprietary
technologies.  The  Company  generally  enters into  confidentiality  or license
agreements with its distributors,  customers and potential  customers and limits
access  to and  distribution  of the  source  code  to its  software  and  other
proprietary  information.  The Company's  employees are subject to the Company's
employment policy regarding confidentiality.  There can be no assurance that the
steps  taken  by the  Company  in  this  regard  will  be  adequate  to  prevent
misappropriation  of its  technologies or to provide an effective  remedy in the
event  of a  misappropriation  by  others.  The  Company  holds no  patents  but
currently  has a patent  review  pending.  There  can be no  assurance  that any
patents will be granted,  or that,  if granted,  such patents  would provide the
Company with meaningful protection from competition.

                                       10
<PAGE>

Although  management believes that the Company's products do not infringe on the
proprietary rights of third parties, there can be no assurance that infringement
claims will not be asserted, resulting in costly litigation in which the Company
may not ultimately  prevail.  Adverse  determinations  in such litigation  could
result in the loss of the Company's  proprietary rights,  subject the Company to
significant liabilities, require the Company to seek licenses from third parties
or prevent the Company from manufacturing or selling its products,  any of which
will have a material  adverse  effect on the  Company's  revenue  and  operating
results.

Because of the existence of a large number of patents in the computer networking
industry  and the rapid rate of issuance of new patents or new  standards  or to
obtain  important new  technology,  it may be necessary for the Company to enter
into technology licenses from others. There can be no assurance that these third
party  technology  licenses  will be  available  to the Company on  commercially
reasonable  terms.  The loss of or inability  to obtain any of these  technology
licenses  could result in delays or  reductions in product  shipments.  Any such
delays or reductions in product shipments will have a material adverse effect on
the Company's revenue and operating results.

Dependence  on  Personnel.  The  Company's  success  depends  on  the  continued
contributions of its personnel,  many of whom would be difficult to replace.  It
will also  depend on its  ability  to  attract  and  retain  skilled  employees.
Although the Company's employees are subject to the Company's  employment policy
regarding  confidentiality  and  ownership  of  inventions,  employees  are  not
otherwise subject to employment agreements or non-competition covenants. Changes
in personnel could adversely affect the Company's operating results.


ITEM 2 - Properties

The Company's principal executive offices, manufacturing and the majority of its
research and development  personnel are located in a 30,000 square foot building
in Rochester,  New York.  The lease for this facility  expires in the year 2001.
The Company has an option to renew the lease for two successive five-year terms.
There is  currently  no excess  office  capacity  at this  facility.  Management
believes  additional  office space will be needed to  accommodate  the Company's
growth in the near  term and that  adequate  office  space is  available  in and
around the Rochester  area. The Company also leases  approximately  6,800 square
feet of office space in San Diego,  California pursuant to a lease which expires
in  November  1999.  This  facility  houses  part  of  the  Company's   software
engineering and sales operations. The Company also leases sales offices at three
other locations.


ITEM 3 - Legal Proceedings

In the normal course of business, the Company is involved in litigation relating
to claims arising out of its operations.  The Company is not a party to any such
legal  proceedings,  the  adverse  outcome  of  which,  individually  or in  the
aggregate,  would have a material  adverse  effect on the  Company's  results of
operations, financial condition or cash flows.


ITEM 4 -  Submission  of Matters to a Vote of Security  Holders 

No  matters  were  submitted  to a vote of  security  holders  during the fourth
quarter of the year ended December 31, 1998.

ITEM 7 - Management's Discussion and Analysis of Financial Condition and Results
of Operations

The  Company's  annual  operating  performance  is subject to various  risks and
uncertainties.  The following  discussion should be read in conjunction with the
Consolidated Financial Statements and related notes included elsewhere herein as
well as the  section  appearing  in Item 1 of this Form 10-K  under the  heading
"Risk  Factors."  The  Company's  future  operating  results  may be affected by
various  trends  and  factors  which are  beyond the  Company's  control.  These
include, among other factors, general business and economic conditions, rapid or
unexpected  changes in  technologies,  cancellation or delay of customer orders,
changes  in  the  product  or  customer  mix of  sales,  delays  in new  product
development,  customer  acceptance  of  new  products  and  customer  delays  in
qualification of products.

Matters discussed in Management's Discussion and Analysis of Financial Condition
and  Results of  Operations  and  elsewhere  in this Form 10-K  include  forward
looking  statements  within the meaning of Section 27A of the  Securities Act of
1933, as amended, and Section 21E of the Securities Act of 1934, as amended, and
are subject to the safe  harbor  provisions  of those  sections.  The  Company's
actual  results  could  differ  materially  from those  discussed in the forward
looking statements.

Overview

The Company achieved record earnings for the fifth  consecutive year in 1998 and
the third  consecutive  year as a publicly  traded  company.  Net income in 1998
amounted  to $5.8  million,  19% of sales,  compared  to $5.1  million  in 1997.
Revenue  was $30.2  million in 1998,  compared  to $30.3  million  in 1997.  The
Company did not meet management's revenue expectations in 1998 primarily because
the award of a  follow-on  Department  of Defense  contract  was  delayed  until
September 1998 and because  completion of the Nebula 8000 fault tolerant network
switch  has been  delayed  until  the  second  quarter  of 1999.  The  Company's
financial  performance  improved  significantly  during the second half of 1998:
Sales  during the second half of the year were 25% higher than in the first half
and  diluted  earnings  per share were $.46,  compared to $.29,  58% higher.  At
year-end  1998,  the  Company  had $25.6  million  in cash and cash  equivalents
($3.38/per  share) and virtually no debt. For 1998, the Company generated income
from  operations,  excluding  depreciation  and  amortization  (EBITDA)  of $8.6
million and cash from operating activities amounted to $6.5 million, compared to
$5.8  million  for 1997.  Return on equity for 1998 was 19% and return on assets
was 17%. During 1998,  international  sales increased to $7.2 million, or 23% of
sales, compared to $3.0 million, or 10% of sales in 1997.

As the Company  enters  1999,  management  is focusing  on the  development  and
delivery of new  products  for two distinct  communications  markets:  Wide Area
Networking communications and Local Area Network Switching.

Wide Area Networking:  The Company's overall Wide Area Networking strategy is to
provide  customers with hardware and software product  solutions which support a
variety of open system platforms and operating  systems.  The growth in the Wide
Area Networking (WAN) communications  market is being driven by the expansion of
the Internet, cellular communications and the convergence occurring between data
communications  and  telecommunications.  At the same time, the technologies for
Wide Area Networking products are changing  dramatically.  Server,  workstation,
and telecommunications  providers are migrating their platforms and applications
from older bus standards such as VMEbus and SBus, to the newer standard hardware
bus  architectures;  PCIBus and  CompactPCI.  These  technology  changes offer a
significant opportunity for the Company. PTI began developing WAN communications
products for the PCIBus market in 1995.  In 1996,  PCIBus  products  represented
less than 7% of the  Company's WAN revenue.  Through a  combination  of internal
development,   licensing  and  strategic  partnering,   the  Company  created  a
comprehensive  group of Wide Area  Networking  communications  products for this
market.  During 1997 and 1998,  PTI WAN  product  revenue  increased  by 90% and
PCIBus  products  represented 48% of the Company's WAN revenue in 1998. The next
emerging WAN market the Company is addressing is  CompactPCI  (cPCI).  cPCI is a
new standard  hardware bus  architecture  that  combines the  attributes  of the
VMEbus and PCIBus into a ruggedized  industrial hardware system for the embedded
OEM marketplace.  The  telecommunications  and defense industries are expressing
great  interest in the cPCI system  architecture  for meeting their  application
requirements. Currently, the Company's cPCI WAN products are being evaluated for
numerous  potential  integration  opportunities  and we expect shipments of cPCI
products in the second half of 1999.

To  complement  the  Company's  hardware  development,   communication  software
protocols have been  developed for the PCIBus and cPCI product lines  including:
Frame  Relay,  Signaling  System #7 (SS7),  X.25,  High-Level  Data Link Control
(HDLC) and a variety of protocols to facilitate high and low speed
communications.

The  markets and  applications  for Wide Area  Network  products  are  expanding
rapidly.  In order to gain broader market  penetration,  the Company established
strategic  partnering  relationships with a number of major server,  workstation
and  telecommunications  equipment suppliers including Sun Microsystems,  Compaq
Computers, Nortel Networks and ADC NewNet, as well as several leading CompactPCI
platform manufacturers.

Local  Area  Network  Switching:  The  Company  has been  developing  its second
generation family of high performance 100Mbit/Gigabit Network Switches for Local
Area  Networks.  During  1998,  the  Company  completed  development  of its new
Nebula(TM)  4000  workgroup   switch  and  its  new  Nebula  6000  high  density
departmental  switch. The centerpiece of the Company's Local Area Network switch
strategy  is the Nebula  8000 Fault  Tolerant  Backbone  Switch.  This  100/1000
Ethernet  switch is the first network switch to offer true fault tolerance at an
affordable  price. The Nebula 8000's redundant switch fabric has been engineered
for maximum  availability and its innovative design ensures that no single point
of failure will shutdown a network.

The market  demands  for fault  tolerant  computing  and  networking  are rising
rapidly.  Server  manufacturers  including Compaq Computers and Tandem Computers
have developed  server clusters to meet their  customers'  fault tolerant server
requirements.  Networking  companies including Novell are actively promoting and
selling  networking  solutions  for mission  critical  applications.  Management
believes that  deployment of its fault tolerant  technologies  in the new Nebula
8000 Backbone  Switch  differentiates  PTI from the other vendors in the network
switching  marketplace.  This new product is being positioned for Ethernet based
business   and   mission    critical    applications   in   enterprises    where
"round-the-clock"  operations demand highly resilient  network  infrastructures.
Prospective  customers in the banking,  brokerage,  medical  imaging and defense
industries are expressing serious interest in this product.

As of March 1999, the Nebula 8000 was operating in a number of early beta sites,
including the Company's communications network.  Additional beta sites have been
selected and units are expected to be installed in these  locations in April and
May. Shipments to customers are expected to commence in the second quarter.

</TABLE>

Year Ended December 31, 1998, compared with the Year Ended December 31, 1997

Sales.  Sales for 1998 were  $30,202,000,  compared to  $30,336,000 in 1997. The
Company's  sales are in one product  segment and are grouped  into five  product
categories: WAN communications products, LAN interface products, Network Systems
products,   Mass  Storage  Interface  products  and  Inter-system   Connectivity
products. Beginning in 1999, sales will be grouped into four product categories:
WAN communications products, LAN interface products, Network Switching and Other
(combining  Network  Systems  products,  Mass  Storage  Interface  products  and
Inter-system Connectivity products).

Shipments of WAN communications  products  represented 58% of sales during 1998,
compared to 47% in 1997. The increase in WAN sales is primarily  attributable to
the development of several new PCIBus products being sold to customers including
Sun  Microsystems,  Compaq  Computers and ADC NewNet.  During 1998,  the Company
experienced  a decline in VMEbus and SBus  revenue as  customers  moved to newer
technologies.  The  Company  has  developed  several  new WAN  products  for the
CompactPCI   market  and  these   products   are  in   evaluation   by  numerous
telecommunications   and  defense  suppliers.   Management  expects  PCIBus  and
CompactPCI  revenue  to  increase  in 1999  while the  VMEbus  and SBus  revenue
declines as these technologies become less prevalent.

Shipments of LAN interface  products  amounted to 20% of sales in 1998 and 1997.
The largest share of the Company's LAN interface  product  business is generated
from Commercial  Off-the-Shelf  (COTS) Department of Defense  projects.  Defense
project  revenue  declined  in 1998 by 13%  because  the award of a  significant
multi-year  contract was delayed until mid-September and interim orders were not
received  during  the  delay  period.  Also in the  third  quarter  of  1998,  a
significant  contract  was  received  from a new OEM  customer  for  PCIBus  LAN
products.  PCIBus products represented almost 13% of LAN revenue in 1998, versus
0% in 1997. Revenue from this OEM customer could approach $1.0 million in 1999.

Shipments of Network Systems products  represented 6% of sales in 1998, compared
to 9% in 1997.  Network  Systems are  primarily  comprised  of  shipments of I/O
subsystems  to an OEM customer  and sales of  specialized  communication  server
hardware and protocol software for specialty WAN  applications.  As anticipated,
shipments to the OEM customer  declined by  approximately $1 million in 1998 and
sales  of  specialized   communication   servers  also  declined  in  1998.  The
engineering staff supporting the server business was reassigned at the beginning
of 1998 to develop software for WAN communications  products.  A further decline
in Network Systems product revenue is expected in 1999 and beyond.

                                       15
<PAGE>

Shipments of Mass Storage  Interface  products for 1998 amounted to 9% of sales,
compared to 14% in 1997.  The  technologies  used in this market are moving from
SBus to PCIBus and from SCSI to Fibre  Channel.  The PCIBus  market has become a
commodity market with greater  competition and lower pricing.  While this market
was also  moving to the  Fibre  Channel  technology,  there  were  delays in the
adoption of standards.  As a result of these factors,  the Company's  PCIBus and
Fibre Channel  products do not effectively  compete in today's market. A further
decline in mass storage product revenue is forecasted in 1999 and beyond.

Shipments of Inter-system  Connectivity products represented 7% of sales in 1998
compared to 10% of sales in 1997.  The Company is not investing in this group of
products and a declining trend for this revenue is expected.

Gross Profit.  Gross profit consists of sales, less cost of goods sold including
materials costs, manufacturing expenses and amortization of software development
costs.  Gross  profit  in  1998  increased  by  $222,000  to  $17,863,000,  from
$17,641,000 in 1997.  Gross margin improved to 59% of sales in 1998, from 58% in
1997. While gross margin for the Company's WAN, LAN interface and Other products
is expected to average 59% or 60% in 1999,  the gross  margin on the new network
switching  products  is  forecasted  to average  approximately  45% for the year
because the Company intends to aggressively price these products in the market.

Total Operating Expenses.  Total operating expenses remained relatively constant
at 34% of sales in 1998 and  1997.  The  Company  increased  its  investment  in
research and development  during 1998, while  controlling  selling and marketing
expenses and reducing its general and administrative expenses.

Selling and marketing  expenses increased to $4,023,000 in 1998, from $3,988,000
in 1997, 13% of sales in 1998 and 1997. During 1998, the Company delayed certain
planned marketing and promotional  activities associated with the Nebula 8000 in
order to coordinate spending with the product's availability.  During the second
half of 1998,  the sales and  marketing  staff for the network  switch group was
increased in order to have a greater impact on sales in 1999. Management intends
to market its new products  aggressively in 1999 and expects sales and marketing
expenses to increase as a percentage of sales.

Research and development  expenses  increased by 12.0% to $4,165,000,  or 14% of
sales in 1998, compared to $3,720,000,  or 12% of sales in 1997.  Recruiting and
hiring engineers continues to be one of the Company's greatest challenges. While
a number of engineers were hired during 1998, the Company  continues to actively
recruit to fill open positions and has engaged outside  engineering  consultants
to assist on new product  development  projects.  The  increase in research  and
development  expenses in 1998 was primarily  the result of new engineers  hired,
outside engineering consultants,  and higher development costs for new products.
Management  believes research and development  expenses can fluctuate  quarterly
during 1999 but will only  increase  modestly as a  percentage  of sales for the
year.

General and administrative  expenses decreased to $2,035,000,  or 7% of sales in
1998,  compared  to  $2,711,000,  or 9% of  sales  in 1997.  While  the  Company
maintains tight control over its general and administrative  expenses, more than
one-half  of the 1998  expense  reduction  was  associated  with the Company not
achieving the internal growth goals and objectives  established in the Company's
1998 annual  incentive  plan.  Management  believes  general and  administrative
expenses should decline as a percentage of sales in 1999.

Other income,  net. Other income consists primarily of interest income from cash
equivalents and marketable securities.  The funds are primarily invested in high
quality Municipal and U.S. Treasury  securities with maturities of less than one
year.

Income Taxes. The provision for income taxes for 1998 is based upon the combined
federal and state effective tax rate of 35%, compared to 38% in 1997.

Year Ended December 31, 1997, compared with the Year Ended December 31, 1996

Sales.  Sales  for 1997  increased  by  $5,493,000  (22%) to  $30,336,000,  from
$24,843,000 for 1996. The Company's  products are grouped into five  categories:
WAN Interface Adapter products, LAN Interface Adapter products,  Network Systems
products,   Mass  Storage  Interface  products  and  Inter-system   Connectivity
products.

Shipments  of WAN  Interface  Adapter  products  amounted to 47% of sales during
1997,  compared to 42% for 1996. This increase is attributable to  introductions
over the last twelve to eighteen  months of several new WAN products and several
new OEM customers  integrating  these products into their product  applications.
Shipments of LAN Interface  Adapter  products for 1997 amounted to 20% of sales,
compared to 21% for 1996.  The largest  share of the  Company's  LAN business is
generated from Commercial  Off-the-Shelf  (COTS) Defense  applications  which is
project-oriented and is difficult to predict on a quarterly basis.  Combined WAN
and LAN sales grew by 30% in 1997 and represented 77% of the Company's  business
in the fourth quarter of 1997.

Shipments of Network Systems products  represented 9% of total sales in 1997 and
11% for 1996.  Network  Systems are  primarily  comprised  of  shipments  of I/O
subsystems to a major OEM customer and specialty protocol software business sold
by the Company's subsidiary, UconX Corporation.  During the first nine months of
1997,  shipments of the I/O subsystem to this customer  represented $1.6 million
of revenue.  Due to what  appears to be a slowdown in orders for the  customer's
product that  incorporates  the Company's I/O subsystem  product,  this customer
requested delays of its fourth quarter  deliveries and has not placed any orders
for  product  deliveries  for the first  half of 1998.  The  specialty  software
protocol   business   is   typically   project-oriented   which  can  result  in
fluctuations.  The  volume of this  business  in 1997 was less  than  originally
forecasted and at the end of 1997, the Company integrated the UconX organization
into its corporate  structure.  The products and services of UconX will continue
to be sold but  future  engineering  efforts  will be more  focused on PTI's WAN
projects.

Shipments of Mass Storage Interface  products for 1997 amounted to 14% of sales,
compared  to 16% in  1996.  The  decrease  in sales  volume  is  believed  to be
attributable to a slow down in the RAID/disk drive market  primarily  associated
with the  Pacific  Rim  economic  issues in the fourth  quarter  and  technology
changes occurring in this market. These changes include customers  transitioning
from SBus to PCIBus  applications  and from the slower  SCSI  adapters to faster
Fibre  Channel  adapters.  The Company has been  transitioning  its products and
customers into these new technologies; however, the decline in the SBus business
has been greater than the increase in the PCI business.

Shipments of Inter-system  Connectivity  products  represented 10% of sales 1997
and 10% of total  sales  1996.  The  Company is not  investing  in this group of
products and a declining trend in these revenues is expected.

Gross Profit.  Gross profit consists of sales, less cost of goods sold including
materials costs, manufacturing expenses and amortization of software development
costs.  Gross  profit for 1997  increased by  $3,647,000  to  $17,641,000,  from
$13,994,000  for 1996 due to increased  sales volumes.  Gross margin  percentage
improved to 58.2% of sales for 1997,  from 56.3% in 1996. The improved margin is
attributable  to  favorable  product mix along with  manufacturing  efficiencies
associated with higher sales volumes.

Total Operating Expenses.  Total operating expenses increased to $10,419,000 for
1997, from $8,907,000 for 1996, but declined as a percentage of sales from 35.8%
in 1996 to 34.3% in 1997.  The Company made  significant  investments  in sales,
marketing,  research and development  during 1997 while reducing its general and
administrative expenses as a percentage of sales.

Selling and marketing  expenses  increased by 24.2% to  $3,988,000,  or 13.1% of
sales for 1997, from  $3,210,000,  or 12.9% of sales for 1996. The Company added
staff to the  sales  and  marketing  departments  resulting  in an  increase  of
compensation-related  expenses  in an effort to promote the  Company's  products
more  extensively  and increase market  penetration.  Spending for marketing and
promotion  increased  in 1997 as  compared to 1996,  primarily  due to the costs
incurred to introduce  the new  switching  products and to improve the Company's
presence in the marketplace.

                                       17

Research and development expenses increased by 25.7% to $3,720,000,  or 12.3% of
sales for 1997, compared to $2,960,000, or 11.9% of sales for 1996. Research and
development  expenses consist primarily of employee salaries and benefits costs,
cost of materials  consumed in  developing  and designing new products and, to a
lesser extent,  contract  development.  Certain engineering  expenses associated
with the  development of software are capitalized and amortized to cost of goods
sold.  The increase in research and  development  expenses in 1997 was primarily
attributable to the hiring of eight additional  engineers and the development of
the new ASIC for the new switching  products.  The Company needs to  continually
invest in new product  development to stay abreast of  technological  changes in
its markets.

General and  administrative  expenses  decreased  to 8.9% of sales for 1997,  or
$2,711,000,  compared to $2,737,000, or 11.0% of sales for 1996. The decrease as
a  percentage  of sales is  primarily  attributable  to  maintaining  control of
administrative expenses.

Other income,  net. Other income consists primarily of interest income from cash
equivalents and marketable securities. The funds are primarily invested in money
market  funds,  high  quality  short  term  commercial  paper and U.S.  Treasury
securities maturing in less than 12 months.

Income Taxes. The provision for income taxes for 1997 is based upon the combined
federal and state  effective  tax rate of 38%,  compared  to 35.6% in 1996.  The
primary  reasons  for the  increase  in the  combined  tax rate  are the  higher
research and  development  tax credits  generated in 1996 and a lower benefit of
state income taxes in 1997.


Liquidity and Capital Resources

At December 31, 1998, the Company's  primary  source of liquidity  included cash
and cash equivalents of $25,627,000 and available borrowings of $5,000,000 under
a revolving credit facility with a bank. No amounts were outstanding  under this
credit  facility as of December  31,  1998.  The Company had working  capital of
$31,790,000 at December 31, 1998, compared to $26,584,000 at December 31, 1997.

Cash generated by operating activities was $6,503,000, $5,821,000 and $3,642,000
in 1998,  1997 and 1996,  respectively.  The  increase  in cash  generated  from
operating  activities in 1998 is attributable to greater net income and non-cash
adjustments offset by a net increase in operating assets and liabilities.

Cash provided by investing  activities was  $10,960,000 in 1998 and cash used in
investing   activities   was   $7,093,000  and  $7,469,000  in  1997  and  1996,
respectively.  During  1998,  investing  activities  included  the  purchase  of
marketable  securities of $6,000,000,  the maturity of marketable  securities of
$18,010,000,  and capital  equipment  purchases of $429,000.  Capital  equipment
purchases  consist  primarily of manufacturing  equipment,  office equipment and
computer and related  equipment used in  engineering.  In addition,  the Company
capitalizes  certain  software   development  costs.  Amounts  capitalized  were
$621,000, $704,000 and $380,000 in 1998, 1997 and 1996, respectively.

In March 1998,  the Board of Directors  authorized  the repurchase of up to $5.0
million of the Company's  Common Stock. As of December 31, 1998, the Company had
repurchased  a total of 78,437  shares at total cost of  $736,000.  The  program
authorized in 1998 is still in effect. Cash provided by financing  activities of
$67,000 and $78,000 for 1998 and 1997, respectively,  was principally the result
of the  exercise of stock  options.  During  1996,  cash  provided by  financing
activities was principally  the result of the Company's  initial public offering
of its Common Stock in January 1996.

Impact of the Year 2000 Issue

Many companies are facing a potential issue regarding the ability of information
systems to  accommodate  the coming year 2000. The Year 2000 issue is the result
of computer  programs  using only the last two digits to indicate  the year.  If
uncorrected, such computer programs will be unable to interpret dates beyond the
year 1999,  which could cause computer  system failure or other computer  errors
disrupting  operations.  The Company  recognizes the importance of the Year 2000
issue and has been giving it high priority. The Company created a corporate-wide
Year 2000  project team and the team's  objective is to ensure an  uninterrupted
transition  into the Year  2000.  The  scope of the Year 2000  readiness  effort
includes (i) information  technology ("IT") such as software and hardware;  (ii)
non-IT systems or embedded technology; and (iii) readiness of key third parties,
including suppliers and customers.  If needed  modifications and conversions are
not made on a timely  basis,  the Year 2000 issue could have a material  adverse
effect on the Company's results of operations or financial condition.

The Company has completed  phase I of its readiness  plan for its IT systems and
non-IT  systems.  This phase  consisted of evaluating  its systems and equipment
based on the current status and normal scheduled upgrade and replacement of such
system  components.  The Company is in the process of completing  Phase II which
consists  of  testing IT system and  non-IT  system  components  whose Year 2000
status  cannot be  determined  by research and has begun  certain parts of Phase
III,  upgrading  its IT system.  The  remaining  parts of Phase III are  planned
during the third quarter 1999, and will consist of upgrading and/or  replacement
of non-IT system components specifically required for Year 2000 readiness. Phase
IV,  planned  during the  fourth  quarter of 1999,  will  consist of  finalizing
contingency plans for temporary operation should unexpected difficulties with IT
systems and non-IT systems occur.  The  development of these  contingency  plans
began in conjunction with upgrading its IT system.

In addition  to internal  Year 2000 IT and non-IT  remediation  activities,  the
Company  has  contacted  key  suppliers  to  assure  no   interruption   in  the
relationship between the Company and these important third parties from the Year
2000 issue.  The Company is waiting for responses from these suppliers to assess
if such third  parties have any known Year 2000 issues.  If third parties do not
convert their  systems in a timely  manner and in a way that is compatible  with
the Company's systems,  the Year 2000 issue could have a material adverse effect
on Company  operations.  The Company believes that its diligent actions with key
suppliers will minimize these risks.

The vast majority of the Company's products are not date sensitive.  The Company
has of  summarized  information  on its products and this  information  has been
available to customers since November 1998.

While the  Company  expects its  internal IT and non-IT  systems to be Year 2000
compliant  by the dates  specified  within its  internal  plan,  the  Company is
working on a  contingency  plan  specifying  what the  Company  will do if it or
important third parties are not Year 2000 compliant by the required  dates.  The
Company expects to have such a contingency  plan finalized by the second half of
1999.

Through  December  1998,  the Company has not incurred  significant  incremental
costs related to the Year 2000 issue.  The total projected  incremental  cost is
estimated to be $150,000. The Company is expensing as incurred all costs related
to the  assessment  and  remediation of the Year 2000 issue unless the nature of
the item is an upgrade or  replacement of a system with a useful life that meets
the capitalization  policy of the Company.  These costs are being funded through
operating cash flows.  The Company's total cost for the Year 2000 issue includes
estimated costs and time associated  with  interfacing  with third parties' Year
2000 issues. These estimates are based on current information.

The  Company's  current  estimates of the amount of time and costs  necessary to
remediate and test its computer systems are based on the facts and circumstances
existing  at this time.  The  estimates  were made using  assumptions  of future
events  including the continued  availability  of certain  resources,  Year 2000
modification  plans,  implementation  success  by key  third-parties,  and other
factors. New developments may occur that could affect the Company's estimates of
the  amount of time and costs  necessary  to modify  and test its IT and  non-IT
systems  for Year  2000  compliance.  These  developments  include,  but are not
limited to: (i) the  availability  and cost of  personnel  trained in this area;
(ii) the  ability  to  locate  and  correct  all  relevant  computer  codes  and
equipment,  and (iii) the  planning  and Year 2000  compliance  success that key
customers and suppliers  attain. 


                                       19
<PAGE>

Year 2000  compliance is an issue for virtually all  businesses,  whose computer
systems and applications may require significant  hardware and software upgrades
or modifications. Companies owning and operating such systems may plan to devote
a  substantial  portion  of their  information  systems'  spending  to fund such
upgrades and  modifications.  It is the Company's  intention to fulfill its plan
and  become  Year  2000  compliant;  however,   uncertainties  exist  about  the
thoroughness  of how other  companies,  vendors,  customers  and  other  service
providers,  that the  Company  does  business  with will be  successful  at also
becoming Year 2000 compliant.  These other  companies,  regardless of the dollar
volume transacted with the Company,  may significantly affect either directly or
indirectly the operations of the Company.  Where  practicable,  the Company will
attempt to mitigate  its risks with  respect to the failure of  suppliers  to be
Year 2000  compliant.  In the event that suppliers are not Year 2000  compliant,
the Company will seek alternative  sources of supplies.  However,  such failures
remain a possibility  and could have an adverse impact on the Company's  results
of operations or financial condition.

ITEM 7A - Quantitative and Qualitative Disclosures About Market Risk 

The Company is exposed to various market risks in the normal course of business,
primarily interest rate risk and changes in the market value of its investments,
and believes its exposure to such risk is minimal. The Company's investments are
made in accordance with the Company's  investment policy and primarily  consists
of U.S. Treasury securities, municipal securities and corporate obligations. The
Company  does  not  participate  in  the  investment  of  derivative   financial
instruments.

             PERFORMANCE TECHNOLOGIES, INCORPORATED AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note A - Nature of Business and Summary of Significant Accounting Policies

The Company: Performance Technologies, Incorporated was formed in 1981 under the
laws of the State of Delaware and maintains its corporate  offices in Rochester,
New  York.  The  Company  designs,  develops,   manufactures  and  markets  high
reliability,  and high availability  network switching and other  communications
solutions.

Segment Data,  Geographic  Information  and Significant  Customers:  The Company
operates in one industry  segment.  Export sales to customers outside the United
States  represent  23%, 10% and 11% of the  Company's  sales for the years ended
December 31, 1998,  1997 and 1996,  respectively.  For 1998, 1997 and 1996, four
customers  accounted for approximately  35%, 28% and 30%,  respectively,  of the
Company's sales, with no single customer  representing  greater than 13%, 8% and
12%, respectively, of the Company's sales.

Principles of Consolidation:  The consolidated  financial statements include the
accounts of the  Company  and its  wholly-owned  subsidiaries.  All  significant
intercompany transactions have been eliminated (Note E).

Use of Estimates:  The  preparation of financial  statements in conformity  with
generally accepted  accounting  principles requires management to make estimates
and assumptions  that affect the reported  amounts of assets and liabilities and
disclosure of  contingent  assets and  liabilities  at year-end and the reported
amounts of revenue and expenses  during the  reporting  period.  Actual  results
could differ from those estimates.

Concentration of Credit Risk: Financial instruments which potentially expose the
Company to significant concentrations of credit risk consist principally of bank
deposits,  marketable securities and accounts receivable.  Marketable securities
consist of high quality short-term interest bearing financial  instruments.  The
Company  performs  ongoing  credit  evaluations  of  its  customers'   financial
condition  and the Company  maintains an allowance  for  uncollectible  accounts
receivable based upon the expected collectibility of all accounts receivable.

Fair Value of  Financial  Instruments:  The  carrying  amounts of the  Company's
financial instruments, including cash and cash equivalents, accounts receivable,
accounts payable,  accrued expenses and loans approximate fair value at December
31, 1998, as the maturity of these  instruments are generally short term. Due to
differences  in the interest  rates on the long term debt compared to prevailing
rates,  the fair  value of these  instruments  does  vary  from  their  carrying
amounts, however, such differences are immaterial.

Cash Equivalents:  The Company considers all highly liquid investments purchased
with an original maturity of three months or less to be cash equivalents.

Marketable  Securities:  The Company has classified  all of its marketable  debt
securities  as held to  maturity  and has  accounted  for these  investments  at
amortized  cost.  Accordingly,  no adjustment  for  unrealized  holding gains or
losses has been  reflected in the  Company's  financial  statements.  Marketable
securities  classified as held to maturity are high credit quality securities in
accordance with the Company's investment policy.

Inventories:  Inventories  are  valued at the lower of cost or market  using the
first-in, first-out method.

Revenue  Recognition:  Revenue from hardware  sales is  recognized  upon product
shipment.

Note A - Nature of  Business  and  Summary of  Significant  Accounting  Policies
(continued)

Equipment and Improvements:  Equipment and improvement purchases are recorded at
cost. Depreciation is computed using the straight-line method over the following
useful lives:

     Machinery and equipment            3-10 years
     Office furniture and equipment     3-5 years
     Leasehold improvements             The lesser of 10 years or the lease term

Upon retirement or disposal of an asset,  the asset and the related  accumulated
depreciation  are eliminated  from the accounts with gains or losses recorded in
the Consolidated Statements of Income.

Research  and  Development:  Research  and  development  costs are  expensed  as
incurred.

Software  Development Costs:  Software  development costs incurred subsequent to
the  establishment of technological  feasibility and prior to general release of
the product are  capitalized  and amortized on a  product-by-product  basis over
their  estimated  remaining  economic life,  generally three years, or using the
ratio of  current  revenues  to  current  and  anticipated  revenues  from  such
software, whichever provides greater amortization.

Income  Taxes:  The  Company  accounts  for  income  taxes  using  the asset and
liability  approach which requires  recognition of deferred tax  liabilities and
assets for the expected future tax consequences of temporary differences between
the  carrying  amounts  and the tax basis of such assets and  liabilities.  This
method utilizes enacted  statutory tax rates in effect for the year in which the
temporary  differences  are  expected to reverse and gives  immediate  effect to
changes in income tax rates upon enactment.  Deferred tax assets are recognized,
net of any valuation  allowance,  for deductible  temporary  differences and tax
credit  carryforwards.  Deferred  income tax expense  (benefit)  represents  the
change in net deferred tax asset and liability balances.

Note G - Long Term Debt and Credit Agreement

During 1998, the Company signed a new two-year  revolving  credit loan agreement
with  a  bank  increasing  the  available  borrowing  capacity  to  $5  million.
Borrowings  bear  interest  ranging  between the bank's  prime rate or one month
LIBOR plus applicable basis points as outlined in the agreement.  Borrowings are
collateralized  by trade accounts  receivable,  inventory,  equipment,  contract
rights and  intangibles.  The  agreement  requires  the Company to meet  certain
financial and non-financial  covenants.  The Company was in compliance with such
covenants at December 31, 1998.  There were no balances  outstanding  under this
agreement at December 31, 1998 and 1997.

In June  1993,  the  Company  borrowed  $80,000  from the City of  Rochester  to
purchase equipment.  The seven year loan bears interest at 2%. The loan is fully
collateralized  by an irrevocable  letter of credit.  This agreement  contains a
covenant  requiring the Company to maintain  substantially all of its operations
located within the  boundaries of the  municipality.  The amount  outstanding at
December 31, 1998 and 1997 was $18,000 and $30,000,  respectively,  and the long
term amount  outstanding  at December  31, 1998 and 1997 was $6,000 and $18,000,
respectively.  As of December 31, 1998,  the  aggregate  maturities  of the loan
payable for the years ending  December 31, 1999 and 2000 are $12,000 and $6,000,
respectively.

Note H - Commitments

The Company leases  facilities and equipment under operating  leases.  Under the
terms of the facility lease for its primary operations which expires in the year
2001,  the Company agrees to pay an annual rental of $270,000 with an adjustment
each year based upon the Consumer  Price Index.  The Company is also required to
pay their pro rata share of the real property  taxes and  assessments,  expenses
and other charges  associated with this facility.  The Company has the option to
renew the lease  for two  successive  periods  of five  years  each at an annual
rental in accordance with the provisions of the lease agreement.

Future minimum lease  payments for all operating  leases having a remaining term
in excess of one year at December 31, 1998 are as follows:

Note I - Stockholders'  Equity

In March 1998,  the Board of Directors  authorized  the repurchase of up to $5.0
million of the Company's  Common Stock.  During 1998, the Company  repurchased a
total of 78,437 shares at a total cost of $736,000.

On July 31, 1997, the Board of Directors declared a three-for-two stock split of
the  Company's  common stock  effected in the form of a stock  dividend  paid on
September  15,  1997.  All  agreements   concerning   stock  options  and  other
commitments  payable in shares of the  Company's  common stock  provided for the
issuance of  additional  shares due to the  declaration  of the stock split.  An
amount equal to the par value of the common shares issued was  transferred  from
capital in excess of par value to the common stock  account.  All  references to
number of shares  and to per share  information  in the  consolidated  financial
statements,  except shares authorized and 1996 common shares, have been adjusted
to reflect the stock split on a retroactive basis.

On January 24, 1996,  the Company  completed the issuance of an  additional  1.6
million shares of its common stock through an initial public offering, resulting
in net proceeds of $11.4 million.

Under the Incentive  Stock Option Plan  established  in 1986, 1.8 million common
shares were reserved for grant by the Board of Directors. Options may be granted
to any officer,  director or employee at not less than the fair market values at
the date of grant  (not less than 110% of the fair  market  value in the case of
holders of more than 10% of the Company's  common stock).  Options granted under
the plan  generally  expire five years from the date of grant and generally vest
20% after one year, 50% after two years and 100% after three years.

With respect to non-qualified options, the Company recognizes a tax benefit upon
exercise  in an amount  equal to the tax effect of the  difference  between  the
option price and the fair market value of the common stock. Tax benefits related
to such non-qualified  stock options are credited to additional paid-in capital.

</TABLE>

At December  31,  1998,  430,267  options  were vested and 704,687  options were
available  for future grant under the stock  option plan.  At December 31, 1998,
75,000 warrants are held by two of the Company's  directors at an exercise price
of $1.83 per share and expire in the year 2000. During 1996, 3,750 warrants were
exercised by an outside director and a consultant.

The Company has adopted the disclosure only provisions of Statement of Financial
Accounting  Standards  No.  123,  "Accounting  for  Stock-Based   Compensation."
Accordingly, no compensation cost has been recognized for the stock option plan.
Had compensation  cost for the Company's stock option plan been determined based
on the fair value at the grant date for awards in 1998 and 1997  consistent with
the provisions of SFAS No. 123, the Company's net income would have been reduced
to the pro forma  amounts of  $4,617,000  and  $4,371,000,  respectively.  Basic
earnings per share would have been reduced to the pro forma  amounts of $.63 and
$.60,  respectively.  Diluted  earnings per share would have been reduced to the
pro forma amounts of $.61 and $.58, respectively.

The assumption  regarding the stock options issued in 1998 and 1997 was that 33%
of such  options  vested  annually.  The  fair  value  of each  option  grant is
estimated on the date of grant using the Black-Scholes option-pricing model with
the  following  weighted-average  assumptions  used for grants in 1998 and 1997:
dividend yield of 0%;  expected  volatility of 62% and 61%;  risk-free  interest
rate of 5.5% and 6.5%; and expected lives of five years.

Note L  - Earnings Per Share

Basic  earnings per share (EPS) is computed by dividing net income  available to
common  stockholders by the weighted average number of common shares outstanding
for the period.  Diluted EPS is computed giving effect to all dilutive potential
common shares that were outstanding during the period. Dilutive potential common
equivalent  shares  consist  of the  incremental  common  shares  issuable  upon
exercise of stock options and  warrants.  The following  table  illustrates  the
calculation of both basic and diluted EPS:

statements  alone,  respectively,  but  shall  remain  applicable  in all  other
respects.

                             ARTICLE 2. THE CREDIT.

         Section 2.01.  Loans. The Bank agrees,  on the terms of this Agreement,
to make one or more  revolving  credit loans and issue  Letters of Credit to the
Borrower  during the period from and  including the date hereof to and including
the  Revolving  Credit  Termination  Date in  amounts  which,  when added to the
aggregate  amount of all Letter of Credit  Exposure and the principal  amount of
all Loans  outstanding  hereunder  shall not  exceed  the  amount of the  Bank's
Commitment  as then in effect.  Subject to the terms of this  Agreement,  during
such period the Borrower may borrow,  repay and reborrow up to the amount of the
Commitment. The Loans may be Prime Loans or Libor Loans (each a "type" of Loan).
The Borrower  shall give the Bank notice of each borrowing to be made under this
ss. 2.01 (other than Loans created as a Reimbursement Obligation) as provided in
ss.  4.03  hereof.  The  Loans  made by the Bank  (including  Loans  created  as
Reimbursement  Obligations)  shall be  evidenced by the  promissory  note of the
Borrower in substantially the form of Exhibit A hereto,  dated as of the Closing
Date, payable to the order of the Bank in a principal amount of $5,000,000,  and
otherwise  duly  completed.  The amount,  type and date of each Loan made by the
Bank,  and all  payments  made on account  of the  principal  thereof,  shall be
recorded  by the Bank on its  books  and,  prior to any  transfer  of the  Note,
endorsed by the Bank on the  schedule  attached to the Note or any  continuation
thereof, provided, however, that the failure of the Bank to endorse the schedule
shall not  affect or impair the  Borrower's  obligation  to repay  Loans and any
interest thereon or other amounts due hereunder. The proceeds of the Loans to be
made by the Bank (other than Loans created as Reimbursement  Obligations) shall,
subject to the terms and conditions of this Agreement,  be made available to the
Borrower by  depositing  such amount,  in  immediately  available  funds,  in an
account of the Borrower maintained with the Bank.

         Section 2.02. Purpose.  The Borrower will use the proceeds of the Loans
as working  capital for its general  corporate  purposes and the  acquisition of
assets in the ordinary course of the Borrower's business.

         Section 2.03. Changes of Commitment.  The Borrower shall have the right
to terminate or reduce the amount of the  Commitment at any time or from time to
time  upon  not  less  than 30  days'  prior  notice  to the  Bank of each  such
termination or reduction,  which notice shall specify the effective date thereof
(which shall be a Banking Day) and the amount of any such reduction and shall be
irrevocable  and effective only upon receipt by the Bank.  The  Commitment  once
terminated or reduced may not be reinstated.

         Section  2.04.  Extension of Revolving  Credit  Termination  Date.  The
Borrower may, by written  request to the Bank not less than 60 and not more than
90 days prior to the Current Termination Date, request that the Revolving Credit
Termination  Date be extended to the Annual Date next subsequent to such Current
Termination Date. Within 30 days following receipt of such request the Bank will
advise the  Borrower in writing  whether it agrees to or denies such  extension,
provided that if the Bank shall fail to so advise the Borrower it will be deemed
to have denied such request.  If the Bank shall agree  thereto,  such  extension
shall  become   effective  as  of  such  Current   Termination  Date  only  upon
satisfaction of the following conditions as of such Current Termination Date, in
form and substance  satisfactory  to the Bank,  unless  expressly  waived by the
Bank:  (a)  no  Default  shall  have  occurred  and  be   continuing;   (b)  the
representations  and  warranties  made by the  Borrower in ss. 7 hereof shall be
true on and as of such date with the same  force and effect as if made on and as
of such date;  (c) the Bank and the  Borrower  shall have  executed an extension
agreement;  and (d) the Borrower shall have furnished to the Bank such corporate
documents and/or opinions of counsel with respect to such extension, as the Bank
may reasonably  request.  Each extension  request by the Borrower under this ss.
2.04 shall constitute a certification by the Borrower to the effect set forth in
clauses  (a) and (b) of the  preceding  sentence  (both  as of the  date of such
notice and, unless the Borrower otherwise notifies the Bank prior to the Current
Termination Date, as of the Current Termination Date).

<PAGE>

         Section 2.05. Letters of Credit. Subject to the terms and conditions of
this Agreement,  Bank shall, upon the request of the Borrower and payment of the
Bank's  customary  fees and expenses in connection  therewith,  issue Letters of
Credit from time to time from and including the date hereof to but excluding the
Revolving Credit  Termination Date up to but not exceeding the lesser of (i) the
aggregate  unused  amount of the  Commitment  (after  subtracting  the Letter of
Credit Exposure),  or (ii) the difference  between  $1,000,000 and the amount of
the Letter of Credit Exposure which exists  immediately prior to the issuance of
such Letter of Credit.  The Borrower agrees that each  Reimbursement  Obligation
shall, immediately upon its creation, be and become a Prime Loan hereunder.

         Section 2.06.  Facility Fee.  Borrower  shall pay to Bank in advance on
each Annual Date a yearly Facility Fee of $7,500 if the Facility is to remain in
effect, in whole,  subsequent to such Annual Date;  provided however that if the
Facility shall be modified or restructured  prior to the occurrence of a Default
or an Event of Default and if the Bank remains the lender under such modified or
restructured  credit facility,  the Bank shall refund to the Borrower a pro rata
portion of the facility  fee which the Borrower has paid in advance  pursuant to
this ss. 2.06 for the following  year based upon the  remaining  portion of such
year for which the Facility shall not remain in effect. Nothing in this ss. 2.06
shall be deemed to prevent the Bank from  charging a fee which is similar to the
Facility Fee and which is mutually  agreed to in writing by the  Borrower  under
any modified or restructured credit facility.

            ARTICLE 3. REPAYMENTS; INTEREST; LATE FEES, PREPAYMENTS.

         Section 3.01. Repayment of Loans. All Loans shall be due and payable in
full,  principal and  interest,  on the Revolving  Credit  Termination  Date. In
addition,  at the end of each Interest Period,  the Borrower will either (i) pay
to the Bank the  principal  of each Loan which is a Libor Loan,  or (ii) convert
the principal  amount of such Libor Loan to another Loan hereunder as continuing
and subsisting indebtedness.

         Section 3.02.  Interest.  The Borrower will pay to the Bank interest on
the  unpaid  principal  amount  of each  Loan  made by the Bank  for the  period
commencing on the date of such Loan to but excluding the date such Loan shall be
paid in full, at the following rates per annum:

         (a) During such periods such Loan is a Prime Loan,  the Prime Rate plus
the Applicable Margin; and

         (b) During such  periods such Loan is a Libor Loan,  for each  Interest
Period relating thereto, the Libor Rate plus the Applicable Margin.

Notwithstanding the foregoing, after an Event of Default and upon written demand
by the  Bank,  the  Borrower  will pay to the Bank  interest  at the  applicable
Default Rate on any principal of any Loan made by the Bank,  and (to the fullest
extent  permitted by law) on any other amount (other than  interest)  payable to
the Bank by the Borrower hereunder or under the Note, which shall not be paid in
full when due (whether at stated  maturity,  by acceleration or otherwise),  for
the period commencing on the date of such written demand, until the same is paid
in full. Accrued interest on each Loan shall be payable monthly on the first day
of each  month  and upon the  payment  or  prepayment  thereof  (but only on the
principal so paid or prepaid),  except that interest payable at the Default Rate
shall be  payable  from time to time  when due on  demand of the Bank.  Promptly
after the  determination  of any interest rate provided for herein or any change
therein, the Bank shall notify the Borrower thereof.

         Section 3.03. Late Fees. If any payment of principal or interest on any
Loan is not received by the Bank within five days after the due date thereof,  a
late fee shall be imposed on such  payment.  The amount of the late fee shall be
(i) in respect of payments of  interest,  1% of the amount of the payment  which
was due, and (ii) in respect of payments of  principal,  4% of the amount of the
payment which was due,  provided further that in either case such late fee shall
not be less than $25 nor more than $100.

         Section 3.04.  Prepayments.

         (a) The  Borrower  shall prepay upon demand by the Bank that portion of
the  outstanding  principal  balance of the Loans,  if any,  which  exceeds  the
Commitment.

         (b) The Borrower shall have the right to prepay Loans, without penalty,
at any time or from time to time, provided that: (i) the Borrower shall give the
Bank notice of each such prepayment as provided in ss. 4.03 hereof;  and (ii) no
Libor  Loan may be  prepaid  on any day other  than the last day of an  Interest
Period  for such  Libor  Loan  except  upon  payment  of a penalty  computed  in
accordance with ss. 5.05 hereof.

                       ARTICLE 4. PAYMENTS; COMPUTATIONS.

         Section 4.01. Payments. Except to the extent otherwise provided herein,
all payments of principal, interest and other amounts to be made by the Borrower
under this  Agreement  and the Note  shall be made in  Dollars,  in  immediately
available  funds,  to the Bank at the Payment  Office for account of the Lending
Office, not later than 2:30 p.m. New York time on the date on which such payment
shall  become due (each such payment made after such time on such due date to be
deemed to have been  made on the next  succeeding  Banking  Day).  The  Borrower
shall,  at the time of making each  payment  under this  Agreement  or the Note,
specify to the Bank the Loans or other amounts payable by the Borrower hereunder
to which such payment is to be applied,  and if the Borrower fails to so specify
or if an Event of Default has  occurred  and is  continuing,  the Bank may apply
such payment in such manner as it may determine to be appropriate, provided that
the Bank shall apply such  payments  first to the principal of Prime Rate loans,
then to the  principal of any other Loans and then to interest on any Loans.  If
the due date of any payment  under this  Agreement  or the Note would  otherwise
fall on a day which is not a Banking  Day,  such date shall be  extended  to the
next  succeeding  Banking Day and interest shall be payable for any principal so
extended for the period of such extension.

         Section 4.02.  Computations.  Interest on Libor Loans shall be computed
on the basis of a year of 360 days and actual days elapsed  (including the first
day but excluding the last day) occurring in the period for which  payable,  and
interest  on Prime  Loans shall be computed on the basis of a year of 365 or 366
days, as the case may be, and actual days elapsed  (including  the first day but
excluding the last day)  occurring in the period for which  payable.  Changes in
interest rate on Prime Loans  resulting  from changes in the Prime Rate shall be
effective for the full day which  constitutes the effective date for such change
in the Prime Rate.

         Section 4.03.  Certain Notices.  Notices by the Borrower to the Bank of
the  termination  or  reduction  of  the  Commitment,   and  of  borrowings  and
prepayments  of Loans  shall be  irrevocable  and  shall  be  effective  only if
received by the Bank not later than 12:00 noon New York time on the date, or the
number  of days  prior to the  date,  of the  relevant  termination,  reduction,
borrowing  or  prepayment  or the first day of such  Interest  Period  specified
below:

    -------------------------------------- -------------------------------------
               Type of Notice                    Date or Number of Days Prior
    -------------------------------------- -------------------------------------
    Termination or reduction                                30 days
    of Commitment
    -------------------------------------- -------------------------------------
    -------------------------------------- -------------------------------------
    Borrowing or prepayment of                         Same Banking Day
    Prime Loans
    -------------------------------------- -------------------------------------
    -------------------------------------- -------------------------------------
    Borrowing or prepayment of                          3 Banking Days
    Libor Loans
    -------------------------------------- -------------------------------------

Each such notice of  termination  or reduction  shall  specify the amount of the
Commitment  to be  terminated  or  reduced.  Each such  notice of  borrowing  or
prepayment  shall  specify  the Loans to be  borrowed  or prepaid and the amount
(subject  to ss.  4.04  hereof) and type of the Loans to be borrowed or prepaid,
the date of borrowing or  prepayment  (which  shall be a Banking  Day),  and the
duration of the Interest  Period.  Each notice  required  hereunder  shall be in
writing,  except that a notice of borrowing may be given orally on the telephone
provided it is confirmed in writing  within two Banking  Days. In the event that
the Borrower  fails to notify the Bank in a timely  manner as set forth above of
any Libor Loan  borrowing to replace any Libor Loan having an expiring  Interest
Period, such Libor Loan will be automatically converted into a Prime Loan on the
last day of the then current Interest Period for such Libor Loan.

<PAGE>

         Section 4.04.  Minimum Amounts.  Except conversions or prepayments made
pursuant to ss. 5 hereof,  each  borrowing  of principal of Loans shall be in an
amount at least equal to $25,000,  and each  prepayment  of  principal  of Loans
shall be in an amount at least equal to $25,000  (borrowings  or  prepayments in
the case of Libor Loans having  different  Interest  Periods  outstanding at the
same time  hereunder  to be  deemed  separate  borrowings  and  prepayments  for
purposes of the foregoing,  one for each distinct Interest Period).  Anything in
this Agreement to the contrary  notwithstanding,  the aggregate principal amount
of Libor Loans of each type having the same  Interest  Period  shall be at least
equal to  $300,000  and,  if any  Libor  Loans  would  otherwise  be in a lesser
principal  amount for any period,  such Libor Loans shall be Prime Loans  during
such period.

                   ARTICLE 5. YIELD PROTECTION AND ILLEGALITY.

         Section 5.01.  Additional Costs.

         (a) The Borrower  shall pay directly to the Bank from time to time such
amounts as the Bank may  reasonably  determine to be necessary to  compensate it
for any costs  which  the Bank  determines  are  attributable  to its  making or
maintaining of any Libor Loans or its obligation to make any Libor Loans, or any
reduction in any amount receivable by the Bank hereunder in respect of any Libor
Loans or such  obligation  (such  increases in costs and  reductions  in amounts
receivable  being  herein  called  "Additional   Costs"),   resulting  from  any
Regulatory  Change  which:  (i)  changes  the basis of  taxation  of any amounts
payable  to the Bank under  this  Agreement  or the Note in respect of any Libor
Loans (other than taxes  imposed on the overall net income of the Bank or of its
Lending Office for any Libor Loans by the jurisdiction in which the Bank has its
principal  office or such  Lending  Office);  or (ii)  imposes or  modifies  any
reserve,  special deposit or similar requirements  relating to any extensions of
credit or other assets of, or any  deposits  with or other  liabilities  of, the
Bank (including any of such Loans or any deposits  referred to in the definition
of "Libor Base Rate" in ss. 1.01 hereof,  but excluding any reserve  requirement
or deposit insurance assessment already included in the calculation of the Libor
Rate); or (iii) imposes any other condition affecting this Agreement or the Note
(or any of such extensions of credit or liabilities)  other than such portion of
the Agreement and the Note which  pertains to Prime Loans.  If the Bank requests
compensation  from the Borrower  under this ss.  5.01(a),  the Borrower  may, by
notice to the Bank,  require  that the Loans of the type with  respect  to which
such  compensation is requested be converted into Prime Loans in accordance with
the provisions of ss. 5.04 hereof.

         (b)  Without  limiting  the  effect of the  provisions  of ss.  5.01(a)
hereof, in the event that, by reason of any Regulatory  Change,  the Bank either
(i) incurs Additional Costs based on or measured by the excess above a specified
level of the amount of a category of deposits or other  liabilities  of the Bank
which  includes  deposits by reference to which the interest rate on Libor Loans
is  determined  as provided in this  Agreement  or a category of  extensions  of
credit or other  assets of the Bank which  includes  Libor Loans or (ii) becomes
subject  to  restrictions  on the amount of such a category  of  liabilities  or
assets which it may hold, then, if the Bank so elects by notice to the Borrower,
the obligation of the Bank to make further Libor Loans shall be suspended  until
such Regulatory Change ceases to be in effect.

         (c) Without limiting the effect of the foregoing provisions of this ss.
5.01 (but without duplication), the Borrower shall pay directly to the Bank from
time to time on request such amounts as the Bank may reasonably  determine to be
necessary  to  compensate  the  Bank  for any  costs  which  it  determines  are
attributable to the maintenance by the Bank (or any Lending Office)  pursuant to
any law or regulation or any  interpretation,  directive or request  (whether or
not having the force of law) of any court or governmental or monetary  authority
following  any  Regulatory  Change,  of capital in respect of its  Commitment or
Loans (such compensation to include, without limitation,  an amount equal to any
reduction  of the rate of return on assets or equity of the Bank (or any Lending
Office)  which  the Bank  could  have  achieved  but for such  law,  regulation,
interpretation, directive or request).

                                      E-12
<PAGE>

         (d) The Bank will notify the Borrower of any event  occurring after the
date of this  Agreement  that  will  entitle  the  Bank  to  compensation  under
paragraph  (a) or (c) of this ss.  5.01 or to convert  Loans  under ss.  5.04 as
promptly as practicable,  but in any event within 30 days after the Bank obtains
actual knowledge thereof; provided, however, that if the Bank fails to give such
notice within 30 days after it obtains  actual  knowledge of such an event,  the
Bank shall,  with respect to compensation  payable  pursuant to this ss. 5.01 in
respect of any costs  resulting  from such  event,  only be  entitled to payment
under this ss. 5.01 or ss. 5.04 for costs  incurred from and after the date that
the Bank  does  give  such  notice;  and  provided  further,  that the Bank will
designate a different  Lending Office for the Loans of the Bank affected by such
event if such designation will avoid the need for, or reduce the amount of, such
compensation  and will not, in the sole opinion of the Bank, be  disadvantageous
to the Bank,  except  that the Bank  shall have no  obligation  to  designate  a
Lending Office located in the United States of America. The Bank will furnish to
the Borrower a certificate setting forth the basis and amount of each request by
the Bank for  compensation  under  paragraph (a) or (c) of this ss. 5.01,  which
amount  will be  determined  in good  faith on an  equitable  basis  such as, if
appropriate,  an  allocation  measured by the  principal  amount of Loans to the
Borrower,  or  commitments  to make Loans to the Borrower,  then  outstanding in
relation to the total amount of loans, or commitments to make loans, made by the
Bank of the type or  character  which has given  rise to the  Additional  Costs.
Determinations  and allocations by the Bank for purposes of this ss. 5.01 of the
effect of any Regulatory Change pursuant to ss. 5.01(a) or (b) hereof, or of the
effect of capital  maintained  pursuant to ss. 5.01(c)  hereof,  on its costs or
rate of return of  maintaining  Loans or its  obligation  to make  Loans,  or on
amounts  receivable  by it in respect of Loans,  and of the amounts  required to
compensate the Bank under this ss. 5.01, shall be conclusive, provided that such
determinations and allocations are made on a reasonable basis.

         Section  5.02.  Limitation  on Types of Loans.  Anything  herein to the
contrary notwithstanding, if the Bank reasonably determines (which determination
shall be conclusive) that interest rates for the relevant  deposits  referred to
in the definition of "Libor Base Rate" in ss. 1.01 hereof are not being provided
in  the  relevant  amounts  or for  the  relevant  maturities  for  purposes  of
determining rates of interest for Libor Loans as provided herein,  then the Bank
shall give the Borrower  prompt notice  thereof,  and so long as such  condition
remains in effect the Bank shall be under no  obligation  to make further  Libor
Loans.

         Section 5.03.  Illegality.  Notwithstanding any other provision of this
Agreement,  in the event that it becomes  unlawful  for the Bank or its  Lending
Office to honor its obligation to make or maintain Libor Loans  hereunder,  then
the Bank shall promptly notify the Borrower thereof and the Bank's obligation to
make Libor Loans shall be  suspended  until such time as the Bank may again make
and  maintain  Libor  Loans and the  Bank's  outstanding  Libor  Loans  shall be
converted into Prime Loans in accordance with ss. 5.04 hereof.

         Section 5.04. Certain Conversions  Pursuant to ss.ss. 5.01 and 5.03. If
the Loans of the Bank of a  particular  type  (Loans of such type  being  herein
called  "Affected  Loans" and such type being herein called the "Affected Type")
are to be  converted  pursuant to ss. 5.01 or 5.03 hereof,  the  Affected  Loans
shall be automatically converted into Prime Loans on the last day(s) of the then
current  Interest  Period(s)  for  the  Affected  Loans  (or,  in the  case of a
conversion  required by ss. 5.01(b) or 5.03 hereof,  on such earlier date as the
Bank may specify to the Borrower) and, unless and until the Bank gives notice as
provided below that the circumstances specified in ss. 5.01 or 5.03 hereof which
gave rise to such conversion no longer exist:  (a) to the extent that the Bank's
Affected Loans have been so converted, all payments and prepayments of principal
which would otherwise be applied to such Affected Loans shall be applied instead
to its Prime Loans;  and (b) all Loans which would otherwise be made by the Bank
as  Loans of the  Affected  Type  shall  be made  instead  as  Prime  Loans.  No
conversion  pursuant  to this ss.  5.04  shall be deemed to be a  prepayment  in
respect of which any  prepayment  premium or  penalty  shall be due,  other than
compensation   which  may  be  payable  under  ss.ss.  5.01  and  5.05  (without
duplication of compensation).

         Section  5.05.  Compensation.  The Borrower  shall pay to the Bank upon
request such amount or amounts as shall be sufficient (in the reasonable opinion
of the Bank) to  compensate  it for any  loss,  cost or  expense  which the Bank
determines are attributable to:

         (a) any  payment or  prepayment  of a Libor  Loan made by the Bank,  or
conversion  of a Libor Loan  pursuant to ss. 5.04, on a date other than the last
day of the Interest Period for such Loan; or

         (b) any failure by the Borrower to borrow a Libor Loan from the Bank on
the date for such borrowing  specified in the relevant notice of borrowing given
pursuant to ss. 4.03 hereof.

Without limiting the effect of the preceding  sentence,  such compensation shall
include an amount  equal to the  excess,  if any,  of (i) the amount of interest
which otherwise would have accrued on the principal  amount so paid,  prepaid or
converted  or not  borrowed  for the  period  from  the  date  of such  payment,
prepayment,  conversion  or  failure  to borrow to the last day of the  Interest
Period  for such Loan (or,  in the case of a failure  to  borrow,  the  Interest
Period for such Loan which would have  commenced on the date  specified for such
borrowing) at the applicable  rate of interest for such Loan provided for herein
over (ii) the  interest  component  of the amount the Bank would have bid in the
London  interbank  market  for  Dollar  deposits  of  leading  banks in  amounts
comparable  to such  principal  amount and with  maturities  comparable  to such
period (as reasonably determined by the Bank). A determination of the Bank as to
the  amounts  payable  pursuant  to this ss.  5.05  shall be  conclusive  absent
manifest error.

         Section 5.06.  Survival.  The  obligations  of the Borrower  under this
Article 5 shall survive the repayment of the Loans.


                        ARTICLE 6. CONDITIONS PRECEDENT.

         Section 6.01.  Initial  Conditions.  The obligation of the Bank to make

organizational documents as the Bank may reasonably require;

other documents,  certificates,  statements, opinions of counsel and information
with respect to the  transactions  contemplated by this Agreement as the Bank or
its counsel may reasonably request.

         Section 6.02. Additional  Conditions  Precedent.  The obligation of the
Bank to make the Loans shall be subject to the further conditions precedent that
on the  date of each  Loan the  following  statements  shall  be  true:  (i) the
representations and warranties contained in Article 7 of this Agreement are true

The Borrower hereby represents and warrants that:

         Section 7.01. Incorporation,  Good Standing and Due Qualification.  The
Borrower  is a  corporation  duly  incorporated,  validly  existing  and in good
standing  under  the  laws of the  jurisdiction  of its  incorporation,  has the
corporate  power and authority to own its assets and to transact the business in
which it is now engaged or proposed to be engaged,  and is duly  qualified  as a
foreign  corporation  and  in  good  standing  under  the  laws  of  each  other
jurisdiction where failure to qualify could have a Material Adverse Effect.

         Section  7.02.  Corporate  Power  and  Authority;  No  Conflicts.   The
execution,  delivery and  performance by the Borrower of the Facility  Documents
have been duly authorized by all necessary  corporate action and do not and will
not: (a) require any consent or approval of its stockholders; (b) contravene its
charter or  by-laws;  (c)  violate  any  provision  of, or require  any  filing,
registration,  consent or approval under, any law, rule, regulation  (including,
without limitation,  Regulation U), order, writ, judgment,  injunction,  decree,
determination or award presently in effect having applicability to the Borrower;
(d) result in a breach of or  constitute a default or require any consent  under
any  indenture  or loan or credit  agreement  or any other  agreement,  lease or
instrument to which the Borrower is a party or by which it or its properties may
be bound or affected;  (e) result in, or require,  the creation or imposition of
any Lien upon or with  respect to any of the  properties  now owned or hereafter
acquired by the  Borrower;  or (f) cause the Borrower to be in default under any
such  law,  rule,  regulation,  order,  writ,  judgment,   injunction,   decree,
determination or award or any such indenture, agreement, lease or instrument.

         Section 7.03. Legally  Enforceable  Agreements.  Each Facility Document
is, or when delivered  under this Agreement will be, a legal,  valid and binding
obligation  of the Borrower or the  Guarantor,  as the case may be,  enforceable
against the Borrower or the  Guarantor in accordance  with its terms,  except to
the  extent  that such  enforcement  may be limited  by  applicable  bankruptcy,
insolvency and other similar laws affecting creditors' rights generally.

         Section 7.04.  Litigation.  Except as disclosed to the Bank, there are,
as of the Closing  Date,  no actions,  suits or  proceedings  pending or, to the
knowledge of any officer of the Borrower,  threatened,  against or affecting the
Borrower  directly before any court,  governmental  agency or arbitrator,  which
have a reasonable likelihood that they may, in any one case or in the aggregate,
have a Material Adverse Effect or materially  impair the ability of the Borrower
to perform its obligations under the Facility Documents.

         Section 7.05. Financial Statements.  The consolidated balance sheets of
the Borrower and its  Consolidated  Subsidiaries as at December 31, 1997 for the
fiscal year then ended and as at  September  30, 1998 for the nine month  period
then ended,  copies of which have been  furnished to the Bank,  are complete and
correct and fairly  present the  financial  condition  of the  Borrower  and its
Consolidated  Subsidiaries as at such dates and the results of the operations of
the Borrower and its  Consolidated  Subsidiaries for the periods covered by such
statements,  all in accordance with GAAP  consistently  applied (subject to year
end adjustments in the case of the interim financial  statements).  There are no
liabilities of the Borrower or any of its  Consolidated  Subsidiaries,  fixed or
contingent,  which are material as to the Borrower and its Subsidiaries taken as
a whole  but are not  reflected  in the  financial  statements  or in the  notes
thereto, other than liabilities arising in the ordinary course of business since
September  30,  1998 to the  Closing  Date.  No  information,  exhibit or report
furnished by the Borrower to the Bank in connection with the negotiation of this
Agreement  contained  any  material  misstatement  of fact or omitted to state a
material fact or any fact necessary to make the statement  contained therein not
materially  misleading.  Since September 30, 1998 to the Closing Date, there has
been no material  adverse  change in the  condition  (financial  or  otherwise),
business or operations of the Borrower and its Subsidiaries taken as a whole.

         Section 7.06.  ERISA. Each of the Borrower and the ERISA Affiliates has
fulfilled its obligations  under the minimum funding  standards of ERISA and the
Code with respect to each Plan and is in  compliance  in all  material  respects
with the presently applicable provisions of ERISA and the Code, has not incurred
any liability to the PBGC or any Plan aggregating in excess of $100,000 which it
has failed to pay when due, and does not have  Unfunded  Vested  Liabilities  in
excess of $100,000.

         Section 7.07.  Subsidiaries and Ownership of Stock. Schedule 1 is as of
the  Closing  Date a  complete  and  accurate  list of the  Subsidiaries  of the
Borrower,  showing the  jurisdiction  of  incorporation  of each and showing the
percentage of the  Borrower's  ownership of the  outstanding  stock of each such
Subsidiary,  together with all other investments, loans, advances, guaranties or
other liabilities undertaken by the Borrower in respect of such Subsidiary.  All
of the  outstanding  capital  stock of each  such  Subsidiary  has been  validly
issued,  is fully paid and  nonassessable  and is owned by the Borrower free and
clear of all Liens.

         Section 7.08. Existing Credit Arrangements and Existing Liens. Schedule
2 is as of  the  Closing  Date  a  complete  and  correct  list  of  all  credit
agreements,  indentures,  guaranties  and  other  investments,   agreements  and
arrangements  presently in effect  providing  for or relating to  extensions  of
credit in respect of which the Borrower or any of its  Subsidiaries is or may be
in any manner directly or contingently  obligated;  and the maximum principal or
face  amounts  of  the  credit  in  question,   outstanding  and  which  can  be
outstanding,  are correctly stated,  and all Liens of any nature given or agreed
to be given as security  therefor are  correctly  described or indicated in such
Schedule. Schedule 2 is also a complete list as of the Closing Date of all Liens
pertaining  to  any  and  all  property  or  assets  of  the  Borrower  and  its
Subsidiaries.

         Section  7.09.  Regulation  U. The Borrower  warrants as of the date of
this Agreement  that it does not own,  directly or indirectly any "margin stock"
(as defined in  Regulation U of the Board of  Governors  of the Federal  Reserve
System),  as supplemented from time to time, and the Borrower warrants as of the
date of each  Loan  that it does not own  "margin  stock" as of the date of such
Loan having an  aggregate  fair market value equal to or greater than 25% of the
fair market value of all of the  Borrower's  assets,  unless the Borrower  shall
have executed a Form FR U-1 (OMB No.  7100-1115) prior to obtaining the proceeds
of the Loan and, in such case, the Borrower  further  warrants that the proceeds
of such Loan are not used for the  purpose,  whether  immediate,  incidental  or
ultimate, of buying or carrying any "margin stock".

         Section  7.10.  Compliance  With  Laws.  Each of the  Borrower  and its
Subsidiaries  have complied in all respects  with all  applicable  laws,  rules,
regulations, and orders, including without limitation,  compliance with all laws
related to the disposal or handling of toxic waste,  and paying  before the same
became delinquent all taxes,  assessments and governmental  charges imposed upon
it or its  property,  except (a) in the case of taxes,  where  contested in good
faith and by proper  proceedings  if appropriate  reserves are  maintained  with
respect  thereto,  or (b) where the failure to comply with a law  (including the
failure to pay taxes,  assessments  and  governmental  charges) would not have a
Material Adverse Effect.

         Section  7.11.  Operation  of  Business.  Each of the  Borrower and its
Subsidiaries possesses all licenses, permits,  franchises,  patents, copyrights,
trademarks and trade names,  or rights  thereto  (collectively,  "Permits"),  to
conduct its business substantially as now conducted and as presently proposed to
be  conducted,  except where the absence of any Permit would not have a Material
Adverse  Effect and, to the best of Borrower's  knowledge,  neither the Borrower
nor any of its  Subsidiaries  is in violation of any valid rights of others with
respect to any of the foregoing.

         Section 7.12.  Hazardous  Materials.  Except as set forth on Schedule 3
hereto:

         (a) Borrower is in substantial  compliance with all Environmental  Laws
applicable  to  Borrower  and has not  received  any  written  notice  from  any
government  alleging  that  Borrower  is  not  so in  compliance,  except  where
noncompliance would not have a Material Adverse Effect;

         (b)  Borrower  possesses  all  licenses,  permits,   registrations  and
authorizations  required  by  applicable  Environmental  Laws  for  the  current
operation of Borrower's  business and is in  substantial  compliance  therewith,
except where the failure to possess same or to comply therewith would not have a
Material Adverse Effect; and

         (c) To the best of Borrower's  knowledge,  the Borrower's assets do not
contain  asbestos  containing   materials,   polychlorinated   biphenyls,   urea
formaldehyde,  underground storage tanks, or hazardous materials,  as defined by

Borrower in a quantity  and manner  requiring  that  notice  thereof be given by
Borrower to any government, except where such notice has been given.

         Section 7.13. No Default on  Outstanding  Judgments or Orders.  Each of
the Borrower and its  Subsidiaries  has  satisfied all judgments and neither the
Borrower nor any of its Subsidiaries is in default with respect to any judgment,
writ, injunction,  decree, or order of any court,  arbitrator or federal, state,
municipal or other governmental authority,  commission, board, bureau, agency or
instrumentality,  domestic or foreign,  except  where such  non-satisfaction  or
default is not likely to have a Material Adverse Effect.

         Section 7.14. No Defaults on Other Agreements. Neither the Borrower nor
any  of its  Subsidiaries  is in  default  in any  respect  in the  performance,
observance or  fulfillment  of any of the  obligations,  covenants or conditions
contained in any agreement or instrument material to its business to which it is
a party,  except  where such  default  is not likely to have a Material  Adverse
Effect.

         Section 7.15.  Labor Disputes and Acts of God. Neither the business nor
the properties of the Borrower or of any of its Subsidiaries,  has been affected
during the  previous  two years by any strike,  lockout or other labor  dispute,
materially and adversely  affecting such business or properties or the operation
of the Borrower or such Subsidiary.

         Section 7.16. Governmental Regulation.  Neither the Borrower nor any of
its  Subsidiaries  is subject to  regulation  under the Public  Utility  Holding
Company Act of 1935, the Investment Company Act of 1940, the Interstate Commerce
Act,  the Federal  Power Act or any other  statute or  regulation  limiting  its
ability to incur indebtedness for money borrowed as contemplated hereby.

         Section 7.17.  Partnerships.  Except as disclosed on Schedule 4 hereto,
neither  the  Borrower  nor  any  of  its  Subsidiaries  is  a  partner  in  any
partnership.

         Section  7.18.  No  Forfeiture.  Neither  the  Borrower  nor any of its
Subsidiaries  or  Affiliates  is  engaged  in or  proposes  to be engaged in the
conduct  of  any  business  or  activity  which  could  result  in a  Forfeiture
Proceeding  and, to the best  knowledge of Borrower,  no  Forfeiture  Proceeding
against any of them is pending or threatened.

         Section 7.19.  Solvency.

         (a) The present  fair market  value of the assets of the Borrower (as a
going concern) after giving effect to all the  transactions  contemplated by the
Facility  Documents  and the funding of all  Commitments  hereunder  exceeds the
amount that will be required to be paid on or in respect of the  existing  debts
and other liabilities, as recorded on the Borrower's consolidated balance sheets
described in ss. 7.05, of the Borrower and its Subsidiaries as they mature.

         (b) To the best knowledge of the Borrower, the Property of the Borrower
does not constitute unreasonably small capital for the Borrower to carry out its
business  as now  conducted  and as proposed to be  conducted  in the  immediate
future including the capital needs of the Borrower.

         (c) The Borrower  does not intend to, nor does it believe that it will,
incur debts  beyond its ability to pay such debts as they  mature  (taking  into
account the timing and amounts of cash to be  received by the  Borrower,  and of
amounts  to be  payable  on or in  respect  of debt of the  Borrower).  The cash
available to the Borrower after taking into account all other  anticipated  uses
of the cash of the  Borrower,  is  anticipated  to be sufficient to pay all such
amounts on or in  respect  of debt of the  Borrower  presently  recorded  on the
Borrower's consolidated balance sheet when such amounts are required to be paid.

         (d) The Borrower  does not believe that final  judgments  against it in
actions  for money  damages  that are  currently  pending  could  reasonably  be
expected to be rendered at a time when, or in an amount such that,  the Borrower
will be unable to satisfy any such judgments  promptly in accordance  with their
terms (taking into account the maximum  reasonable  amount of such  judgments in
any such actions and the earliest  reasonable time at which such judgments might
be rendered).  The cash  available to the Borrower after taking into account all
other anticipated uses of the cash of the Borrower (including the payments on or
in  respect  of  debt  referred  to in  paragraph  (c) of  this  ss.  7.19),  is
anticipated  to be sufficient to pay all such  judgments  promptly in accordance
with their terms.

         Section  7.20.  Year  2000.  Attached  hereto  as  Schedule  5  is  the
Borrower's  statement  regarding  Borrower's  assessment  of  any  reprogramming
required to permit the proper  functioning,  in and  following the year 2000, of
(i) the Borrower's  computer  systems,  and (ii) equipment  containing  embedded
microchips  (including  systems and  equipment  supplied by others or with which
Borrower's systems interface) and the testing of all such systems and equipment.
To the extent such testing is scheduled  for  completion  after January 1, 1999,
the Borrower will use its best efforts to adhere to that  schedule.  The cost to
the Borrower of such reprogramming and testing and of the reasonably foreseeable
consequences  of  year  2000 to the  Borrower  (including,  without  limitation,
reprogramming  errors and the failure of others'  systems or equipment) will not
result  in a  Default  or a  Material  Adverse  Effect.  Except  for such of the
reprogramming  referred to in the preceding  sentence as may be  necessary,  the
computer and management information systems of the Borrower and its Subsidiaries
are and, with ordinary course upgrading and  maintenance,  will continue for the
term of this  Agreement to be,  sufficient to permit the Borrower to conduct its
business without Material Adverse Effect.


                        ARTICLE 8. AFFIRMATIVE COVENANTS.

         So long as any  portion  of the Note  shall  remain  unpaid or the Bank
shall have any Commitment under this Agreement, the Borrower shall:

         Section  8.01.  Maintenance  of  Existence.  Preserve  and maintain its
corporate  existence and good standing in the jurisdiction of its  incorporation
(which may be any state of the United  States of America and may be changed from
time to time), and qualify and remain qualified as a foreign corporation in each
jurisdiction where failure to qualify could have a Material Adverse Effect.

         Section  8.02.  Conduct of  Business.  Continue,  and cause each of its
Subsidiaries to continue,  to engage in an efficient and economical  manner in a
business  of the  same  general  type  as  conducted  by it on the  date of this
Agreement,  provided,  however,  that nothing in this ss. 8.02 shall prevent the
abandonment  or  termination  of a line of business or of any  Subsidiary if the
Borrower  or a  Subsidiary  determines  that the  preservation  of such  line of
business is no longer  desirable  in the conduct of the business of the Borrower
or such Subsidiary.

         Section 8.03.  Maintenance  of Insurance.  The Borrower  shall maintain
insurance  against risk of loss on its inventory in amounts,  under policies and
with insurers reasonably acceptable to the Bank. In addition, to the extent that
other  insurance is available to the Borrower and each of its  Subsidiaries at a
price comparable to the price paid by other Persons in the same or similar types
of business conducted by the Borrower and each Subsidiary,  maintain,  and cause
each of its  Subsidiaries  to maintain,  insurance  with  financially  sound and
reputable  insurance companies or associations in such amounts and covering such
risks as are  usually  carried  by  companies  engaged  in the same or a similar
business and similarly  situated,  which  insurance  may provide for  reasonable
deductibility  from coverage thereof.  To the extent such other insurance is not
obtained,  adopt, in lieu of or supplemental to such insurance,  such other plan
or method of protection,  whether by the  establishment  of an insurance fund or
reserve  to be held  and  applied  to  make  good  losses  from  casualties,  or
otherwise,  and conforming to the practices of similar corporations  maintaining
systems of self-insurance.

         Section  8.04.  Compliance  with  Laws.  Comply,  and cause each of its
Subsidiaries  to  comply,  in all  respects  with all  applicable  laws,  rules,
regulations  and  orders,   such  compliance  to  include  without   limitation,
compliance with all laws related to the disposal or handling of toxic waste, and
paying before the same become delinquent all taxes, assessments and governmental
charges  imposed upon it or upon its property,  except (a) in the case of taxes,
where contested in good faith and by proper proceedings if appropriate  reserves
are maintained with respect  thereto,  or (b) where the failure to comply with a
law would not have a Material Adverse Effect.

         Section 8.05.  Right of Inspection.  Upon reasonable  notice and during
normal business hours,  permit the Bank or any agent or representative  thereof,
to examine and make copies of and abstracts  from the financial  records of, and
visit the  properties  of,  the  Borrower  and any of its  Subsidiaries,  and to
discuss  the  affairs,  finances  and  accounts  of the  Borrower  and any  such
Subsidiary  with  any  of  their  respective  officers  and  directors  and  the
Borrower's  independent  accountants,  provided that the Borrower  shall receive
reasonable  notice  of  any  such  meetings  with  the  Borrower's   independent
accountants  and the  Borrower  shall  have  the  right  to be  present  at such
meetings.

this  Agreement,  the  Note,  or any other  documents  referred  to herein  (the
participant's  rights  against the Bank in respect of such  participation  to be
those  set  forth  in  the  agreement  executed  by the  Bank  in  favor  of the
participant  relating  thereto) and all amounts  payable by the  Borrower  under

objection to venue in such State and any objection to an action or proceeding in
such State on the basis of forum non  conveniens.  The Borrower  further  agrees
that any action or proceeding  brought against the Bank shall be brought only in
New York State or United States Federal court sitting in Monroe County.

         (b)  Nothing in this ss.  12.08  shall  affect the right of the Bank to

the Bank to bring any action or proceeding  against the Borrower or its property
in the courts of any other jurisdictions.

         (c) To the extent that the Borrower  has or  hereafter  may acquire any
immunity  from  jurisdiction  of any  court or from any legal  process  (whether
through service or notice,  attachment  prior to judgment,  attachment in aid of
execution,  execution or otherwise) with respect to itself or its property,  the
Borrower hereby  irrevocably  waives such immunity in respect of its obligations
under this Agreement and the Note.

such invalidity or unenforceability without in any manner affecting the validity
or enforceability  thereof in any other jurisdiction or the remaining provisions
hereof in any jurisdiction.
