PART I
ITEM 1. BUSINESS

Introduction

Interphase Corporation and subsidiaries ("Interphase" or the "Company")
designs, develops, manufactures, markets and supports high-performance
connectivity products utilizing advanced technologies being used in next-
generation telecommunication networks and enterprise data/storage networks.
Interphase's products include telecom server communication controllers,
server-based adapter cards, network operating system device drivers,
software development tools and management software applications.

Key Terms and Definitions

Interphase is a technology company and many terms used by the Company may be
unfamiliar to those outside the industry. Following are some key terms that
may be useful in helping the reader understand the products, technologies
and markets relevant for the Company.

Adapter - Also called a host bus adapter (HBA) or network interface card
(NIC). An adapter is a device that connects a computer server to one or
more peripheral devices (such as switches, hubs, storage devices, etc.) or
other computers. An adapter card typically plugs into the expansion bus on
the motherboard of the computer and communicates with the operating system
controlling the system via the use of specific device drivers.

AIN - (Advanced Intelligent Network) The primary architecture of the public
switched telephone system (PSTN) in the 1990s, which provides enhanced
voice, video and data services and dynamic routing capabilities. It uses
digital switches known as Signal Switching Points (SSPs) that query
databases in computer systems known as Service Control Points (SCPs).

ATM - (Asynchronous Transfer Mode) A network technology for both LANs and
WANs that supports real time voice and video as well as data. The topology
uses switches that establish a logical circuit from end to end, which
guarantees a quality of service (QoS) for that transmission. However, unlike
telephone switches that dedicate circuits end to end, unused bandwidth in
ATM circuits can be appropriated whenever available. For example, idle
bandwidth in a videoconference circuit can be used to transfer data. ATM is
also highly scalable and supports transmission speeds of 1.5, 25, 100, 155,
622 and 2488 Mbps.

Broadband - A transmission facility (communications link) that has bandwidth
(capacity) greater than a voice grade line.

Communications Controller - Communications I/O adapter (similar to a network
interface card) designed specifically for carrier-grade computer systems
that often support signaling, switching and routing networks. Communication
controllers must conform to specifications that maintain overall system
compliance to the rigorous performance and reliability standards that apply
to telecom service provider equipment into which they are integrated.


CompactPCI - An industrial grade variation of the PCI bus standard that
utilizes the Eurocard (VME) form factor. CompactPCI has been widely adopted
by telecom equipment suppliers because of its high-density connectors,
support for front or rear I/O access and hot-swap capabilities important for
"Five 9's" (99.999%) reliability.

Device Drivers - A program routine that links an adapter card (or other
device) to the operating system. It is written by software engineers who
understand the detailed knowledge of the adapter's command language and
characteristics and contains the precise machine language necessary to
perform the functions requested by the application. When a new adapter is
added to the computer, its driver must be installed in order to run it. The
operating system calls the driver, and the driver "drives" the adapter.
Routines that perform internal functions, such as memory managers and disk
caches, are also called drivers.

DSL - A relatively new broadband technology that carries data signals up to
20 times faster than 56K dial-up modems on the high-frequency portions of
phone lines that also transmit voice. Unlike with dial-up services, DSL
users don't dial a phone number to log on to the Internet. Like cable-modem
service, a DSL line is continuously open. DSL requires two modems, one at
the customer end and one at the phone company end (called a DSLAN), which
communicate constantly with each other. DSL providers don't usually sell
their services directly to consumers - they typically resell them through
Internet service providers such as America Online and Mindspring.

Broadband telecom controllers System - As related to Interphase, an
Broadband telecom controllers system is a highly specialized computer server
that resides in an "industrial" environment requiring high-availability and
maximized "up-time." Typical uses for this type of server include military
applications such as on-board ship communications or avionics, or next-
generation telecommunication applications such as intelligent call routing,
call number portability or base station communications control for wireless
service.

Fast Ethernet - A variation of the Ethernet standard (10Base-T) that
provides 100 Mbps transmission bandwidth, and up to 200 Mbps total I/O
throughput with full duplex operation.

Fibre Channel - A high-speed transmission technology that can be used as a
front-end communications network, a back-end storage network, or both at the
same time. With Fibre Channel, servers can not only talk to the storage
system via SCSI (storage protocol, see below), but the hosts can talk to
each other via IP (Internet Protocol) over the same network. Fibre Channel
supports existing peripheral interfaces and communications protocols. Its
name is somewhat misleading, as Fibre Channel supports coaxial cable and
twisted pair copper wiring as well as single mode and multimode fiber
connections.

Frame Relay - A high-speed packet switching protocol used in wide area
networks (WANs). Providing a granular service of up to DS3 speed (45 Mbps),
it has become very popular for LAN-to-LAN connections across remote
distances. All the major telecommunications carriers offer frame relay
services. Frame relay is much faster than X.25 networks, the first packet-
switching WAN standard, because frame relay was designed for today's
reliable circuits and performs less rigorous error detection.


Gigabit Ethernet - An Ethernet technology that raises transmission speed to
one Gbps and is used primarily for backbone networks and high-speed server-
to-server connectivity.

ISDN - A system of digital connections that has been available for over a
decade and has gained increased use in the last few years for high-speed
data and video transmission.

LAN - (Local Area Network) A short distanced data communications network
that is contained within a building or complex. Its primary use is to link
computers and peripheral devices (such as printers) and to provide
individuals with access to databases and applications running on servers
attached to the network. Anyone connected to the LAN can send messages to
and work jointly with others on the network.

NAS - (Network Attached Storage) A network topology that provides a common
pool of storage that can be shared by multiple servers and clients,
regardless of their file system or operating system. Network Attached
Storage servers are self-contained, intelligent devices that attach directly
to an existing LAN. A file system is located and managed on the NAS server
and data is transferred to network clients over industry standard network
protocols such as IP (Ethernet).

Operating System - The master control program that runs the computer. It is
the first program loaded when the computer is turned on, and its main part,
called the kernel, resides in memory at all times. It may be developed by
the vendor of the computer it's running in or by a third party. It is an
important component of the computer system because it sets the operational
guidelines for all application programs that run on the system. All programs
must "talk to" the operating system. Popular network operating systems
today include Windows NT and 2000, HP-UX, AIX and Linux.

PCI - A bus standard (Peripheral Components Interconnect) that is currently
the main general-purpose bus in virtually every desktop computer and a
majority of servers throughout the world.

PCI-X - A high-performance extension to the PCI Local Bus that is designed
to meet the increased I/O demands of technologies such as Fibre Channel,
Gigabit Ethernet, and Ultra3 SCSI.

PMC - (PCI Mezzanine Card) a low profile mezzanine card that is
electronically equivalent to the Peripheral Component Interconnect (PCI)
specification. PMC cards are used as a quick and cost-effective method to
add modular I/O to other card formats such as VME and CompactPCI.

Remote Access Server - A remote access server is a computer that provides
access to remote users (such as telecommuters, road warriors and branch
office locations) via analog or digital modems and ISDN connections.

SAN - (Storage Area Network) A flexible "any-to-any" networking
infrastructure linking multiple servers to multiple storage devices. Based
on Fibre Channel technology, SANs have recently emerged as the highest
performance data communications environment available today to interconnect
servers and storage. Running at Gigabit speeds, SANs offer better
scalability, fault recovery and general manageability than current client-
server LAN-based approaches for real-time and data intensive applications.
Storage Area Networks are being widely deployed for video editing, prepress
and data mining applications throughout the general IT marketplace.


SCSI - (Small Computer System Interface) Pronounced "skuzzy," SCSI is a
widely used communications technology for connecting computer servers to
storage devices. The technology is especially popular in applications where
network servers are attached to numerous SCSI drives and configured as
fault-tolerant RAID clusters. In the event one drive fails, the system is
still operational. SCSI-based RAID is widely used in file servers, database
servers and other network servers. Interphase products utilize Ultra2 SCSI,
which provides up to 80 Mbps data throughput and Ultra3 SCSI, which doubles
the throughput to 160 Mbps.

Server - A computer in a network shared by multiple users. These are
typically more powerful than computers used by individuals (often referred
to as "desktops") and require advanced I/O connectivity. In enterprise
network environments, some computers may be dedicated to a single task. For
instance, an Internet server is a computer that provides World Wide Web
services on the Internet. If the Web server is used internally and not by
the public, it may be known as an "intranet server."

SS7 - (Signaling System 7) The protocols used in the U.S. telephone system
for setting up calls and providing modern transaction services such as
caller ID, automatic recall and call forwarding. When you dial "1" in front
of a number, SS7 routes the call to your long distance carrier. It also
routes local calls based on the first three digits of the phone number.

T1 - A digital transmission link with a capacity of 1.544 Mbps (1,544,000
bits per second). T1 links normally handle 24 voice conversations, but with
digital encoding can handle many more voice channels. T1 lines are also
used to connect networks across remote distances. The European equivalent
(E1) handles 30 voice channels.

T3 - A digital transmission link equivalent to 28 T1 lines. Providing a
capacity of 45 Mbps, a T3 link is capable of handling 672 voice
conversations.

WAN - (Wide Area Network) A communications network that covers a wide
geographic area, such as state or country. A WAN typically extends a LAN
(Local Area Network, see above) outside the building, over telephone common
carrier lines to link to other LANs in remote locations, such as branch
offices or at-home workers and telecommuters. WANs typically run over
leased phone lines, but are increasingly also employing the Internet for VPN
(virtual private network) connectivity.

this success has been due to the superior pre- and post-sale service the
Company delivers to customers. With a vertically integrated account
perspective, Interphase provides flexibility, timely response and other
customized account service features. Further, the Company's technical
support is divided into functional groups supporting either server I/O or
telecommunication product offerings, allowing Interphase to specifically
focus its support efforts for the different needs and requirements of its
customers in these differing market segments.

Expanding the company's base of quality channel partners.

In keeping with its efforts to expand the total available market for its
product offerings, Interphase continues to build a broad base of
distribution channel partners that provide cost-effective penetration into
the enterprise IT segment. Through its Gold Rush Partners Program, the
Company recruits high-end resellers (VARs) and systems integrators that are
building storage-centric solutions for their enterprise customers.


Developing strategic partnerships.

Interphase is an acknowledged leader in multi-vendor interoperability. The
Company leverages this leadership position into strategic partnerships with
its Diamond Developer Partners Program. Through this program, Interphase
builds synergistic marketing and technical relationships with other key
suppliers in its respective markets. Rigorous product testing and early
access to new partner product releases allows tighter product integration
and helps assure compatibility for the Company's end-user customers.

New Product Development

The markets for the Company's products are characterized by rapid
technological development, evolving industry standards, frequent new product
introductions and relatively short product life cycles. The Company's
success is substantially dependent upon its ability to anticipate and react
to these changes, maintain its technological expertise, expand and enhance
its product offerings in existing technologies, and develop, in a timely
manner, new products in emerging technologies that achieve market
acceptance. The Company believes it must offer products to the market that
not only meet ever-increasing performance and quality standards, but also
provide compatibility and interoperability with products and architectures
offered by various computer and network systems vendors. The continued
utility of the Company's products can be adversely affected by products or
technologies developed by others.

The Company has been engaged in the development of new products and the
refinement of its existing products since its inception. Interphase has
been active in the formulation of industry standards sanctioned by groups
such as the IEEE, ANSI, VME International Trade Association (VITA), Fibre
Channel Industry Association (FCIA), Infiniband Trade Association (ITA), PCI
Industrial Manufacturers Group (PICMG), Project UDI, Fast Ethernet Alliance,
SCSI Committee, the LADDIS Group, ONC/NFS Consortium, University of New
Hampshire FDDI Interoperability Lab, FC-Open (Fibre Channel) Consortium, and
ANTC Consortium for FDDI interoperability testing.


Marketing and Customers

The Company's standard products are sold to OEM's for inclusion in
scientific, industrial, medical, engineering workstations, printing, mini-
supercomputer, graphics and other computer applications. These purchasers
incorporate the Company's products in proprietary systems for resale to
distributors, system integrators and VAR's (which may add specially designed
software) prior to resale to end-users. Also, the Company sells products
directly to sophisticated end-users such as large corporations, universities
and scientific research organizations. During 2000, sales to Hewlett
Packard and Terayon Communication Systems accounted for $10 million or 18%
and $5.9 million or 11% of consolidated revenues, respectively, and were the
only customers accounting for more than 10% of consolidated revenues.
During 1999, sales to Hewlett Packard accounted for $36.9 million or 50% of
consolidated revenues, and was the only customer accounting for more than
10% of consolidated revenues. During 1998, sales to Hewlett Packard
accounted for $28.3 million or 41% of consolidated revenues, and was the
only customer accounting for more than 10% of consolidated revenues.

The Company markets its products through its own sales organization and, to
a lesser extent, through a network of independent sales representatives. In
addition to the Company's headquarters in Dallas, Texas, the Company has
sales offices located in or near Santa Clara, California; Boston,
Massachusetts; Minneapolis, Minnesota; Paris, France and Bangkok, Thailand.
The Company's sales personnel market products directly to key customers as
well as support the sales representative network. In addition, the Company
has entered into distribution agreements with key national and international
distribution partners, including Ingram Micro, Tech Data, Fuji-Xerox,
Gates/Arrow and Macnica.

Interphase emphasizes its extensive product support, training and field
support to its customers. The Company's products are generally sold with a
one to three-year warranty covering components and labor. After the
expiration of the warranty period, the Company generally provides support
services for a stated flat fee.

The Company and its customers generally enter into written agreements
specifying, among other items standard in commercial agreements, product
specifications, failure rates, shipping requirements, shipment rescheduling
terms, price/volume schedules and manufacturer warranties. Substantially all
of these agreements do not contain determinable purchase commitments of the
customers, providing instead that actual purchase and shipments of products
be made by specific purchase order. Accordingly, any shipment dates stated
in such contracts are subject to rescheduling and/or cancellation, and
therefore are not indicative of the future purchase orders to be submitted
by such customer. In addition, the actual terms of the contracts tend to be
modified in the ordinary course of business by means of subsequent purchase
order terms and by course of dealing.

The Company does not believe that the level of backlog of orders is either
material or indicative of future results, since its contracts are subject to
revision through subsequent purchase orders and its customers are generally
permitted to cancel purchase orders, within certain parameters, prior to
shipment without penalty.

The majority of the Company's sales are to OEMs with payment terms typically
being net 30-45 days from the date of invoice.


Manufacturing and Supplies

Manufacturing operations are currently conducted at the Company's
headquarters in Dallas, Texas. The Company's products consist primarily of
various integrated circuits, other electronic components and firmware
assembled onto an internally designed printed circuit board.

The Company uses internally designed applications specific integrated
circuits ("ASIC"), some of which are sole-sourced, on some of its products
as well as standard off-the shelf items presently available from two or more
suppliers. Historically, the Company has not experienced any significant
problems in maintaining an adequate supply of these parts sufficient to
satisfy customer demand. The Company believes that it has good relations
with its vendors.

The Company generally does not manufacture products to stock in finished
goods inventory, as substantially all of the Company's production is
dedicated to specific customer purchase orders. As a result, the Company
does not have any material requirements to maintain significant finished
goods inventories.

Intellectual Property and Patents

While the Company believes that its success is ultimately dependent upon the
innovative skills of its personnel and its ability to anticipate
technological changes, its ability to compete successfully will depend, in
part, upon its ability to protect proprietary technology contained in its
products. The Company does not currently hold any patents relative to its
current product lines. Instead, the Company relies upon a combination of
trade secret, copyright and trademark laws and contractual restrictions to
establish and protect proprietary rights in its products. The development
of alternative, proprietary and other technologies by third parties could
adversely affect the competitiveness of the Company's products. Further,
the laws of some countries do not provide the same degree of protection of
the Company's proprietary information, as do the laws of the United States.
Finally, the Company's adherence to industry-wide technical standards and
specifications may limit the Company's opportunities to provide proprietary
product features capable of protection.

The Company is also subject to the risk of litigation alleging infringement
of third party intellectual property rights. Infringement claims could
require the Company to expend significant time and money in litigation, pay
damages, develop noninfringing technology or acquire licenses to the
technology, which is the subject of asserted infringement.

The Company has entered into several nonexclusive software licensing
agreements that allow the Company to incorporate software into its product
line thereby increasing its functionality, performance and interoperability.


Employees

At December 31, 2000, the Company had 197 full-time employees, of which 70
were engaged in manufacturing and quality assurance, 71 in research and
development, 31 in sales, sales support, service and marketing and 25 in
general management and administration.


The Company's success to date has been significantly dependent on the
contributions of a number of its key technical and management employees.
The loss of the services of one or more of these key employees could have a
material adverse effect on the Company. In addition, the Company believes
that its future success will depend in large part upon its ability to
attract and retain highly skilled and motivated technical, managerial, sales
and marketing personnel. Competition for such personnel is intense.

None of the Company's employees are covered by a collective bargaining
agreement and there have been no work stoppages. Additionally, the Company
considers its relationship with its employees to be good.

Competition

The computer network industry is intensely competitive and is significantly
affected by product introductions and market activities of industry
participants. The Company expects substantial competition to continue. The
Company's competition includes vendors specifically dedicated to the storage
I/O and telecommunication product markets. Traditionally the Company's
major OEM customers have chosen not to manufacture adapters for their
products or do not manufacture sufficient quantities or types of controllers
to meet their needs. Increased competition could result in price
reductions, reduced margins and loss of market share.


ITEM 2. PROPERTIES.

The Company leases a 96,000-square foot facility located in Farmers Branch,
Texas, a suburb of Dallas. The facility includes approximately $2.9 million
in leasehold improvements that were made by the Company. The lease,
inclusive of renewal options, extends through 2002. In addition, the
Company leases a facility in Chaville, France (near Paris) that supports the
European markets. The Company believes that its facilities and equipment are
in good operating condition and are adequate for its operations. The
Company owns most of the equipment used in its operations. Such equipment
consists primarily of engineering equipment, manufacturing and test
equipment and fixtures.

The Company had approximately 4,800 beneficial owners of its common stock,
of which 64 are of record as of March 1, 2001.

The Company has not paid dividends on its common stock since its inception.
The Board of Directors does not anticipate payment of any dividends in the
foreseeable future and intends to continue its present policy of retaining
earnings for reinvestment in the operations of the Company.

The Board of Directors has adopted a Shareholder Rights Plan whereby each
holder of record as of December 29, 2000 received a right to purchase from
the Company one share of common stock of the Company at a price of $93 per
share for each share held. These rights can only be exercised after certain
events occur, such as if a person or entity acquires, or makes a tender or
exchange offer to acquire 15% or more of the Company's common stock and the
rights expire ten years from the record date. Upon acquisition of 15% or
more of the Company's common stock, each right not owned by the acquiring
person or group will be adjusted to allow the purchase for $93 of a number
of shares having a then market value of $186. These rights are intended to
provide the Company certain antitakeover protections. The Board of
Directors may terminate the Rights Plan, or redeem the rights for $0.01 per
right, at any time until the tenth business day following a public
announcement of a 15% or more stock acquisition. The Company has reserved
7,000,000 shares of common stock for this plan.

The rights were distributed to shareholders as of the record date as a non-
taxable dividend. The rights are attached to and trade with Interphase
common stock until the occurrence of one of the triggering events, at which
time the rights would become detached from the common stock.

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




RESULTS OF OPERATIONS

In September 1999, the Company completed the sale of its Voice Over Internet
Protocol ("VOIP") business. Accordingly, the Company's consolidated
financial statements and notes included herein, for all periods presented
reflect the VOIP business as a discontinued operation in accordance with
Accounting Principles Board Opinion No. 30.

Revenues consist of product revenues and are recognized in accordance with
SEC Staff Accounting Bulletin (SAB) 101, "Revenue Recognition." Product
revenues are recognized upon shipment, provided fees are fixed and
determinable, a customer order is obtained, and collection is probable.
Revenues from reseller agreements are typically recognized when the product
is sold through to the end customer. Deferred revenue consists of revenue
from reseller arrangements and certain arrangements with extended payment
terms.

Revenues: Total revenues for the years ended December 31, 2000, 1999 and
1998 were $55.7 million, $73.5 million and $68.7 million, respectively.

Revenues decreased 24% in 2000 compared to 1999. The decrease in revenue
was primarily attributable to the effects of the transitional period where
the Company is refocusing its efforts on its new Fibre Channel and Telecom
Communication Controller products. During this period, several of the new
Fibre Channel products experienced delays in the engineering phase. Due to
the intense competition in the industry, these delays had a significant
impact on sales during 2000. Additionally, 30% of the revenues in 1999 were
attributable to Hewlett Packard's purchases of a Fibre Channel product,
which ceased in the first quarter of 2000. The decrease in revenues during
2000 was partially offset by sales of products through an end-of-life
program instituted in 2000 for many of the Company's legacy products. The
Company began this program in an effort to focus its resources on its new
product lines.

The growth in revenues from 1998 to 1999 was 7%. The increase in revenue
was attributable to growth in the Company's Storage and Broadband telecom
controller product lines, partially offset by a decline in LAN and WAN
products. In 1999, Storage revenues, which consist of Fibre Channel and
SCSI technologies, accounted for approximately 48% of total revenues, LAN
revenues which consist of FDDI, Fast Ethernet, ATM and Ethernet, accounted
for 36% of total revenues, WAN accounted for 7% of total revenues and
Broadband telecom controllers accounted for 9% of total revenues. North
American revenues grew 14%, Pacific Rim revenues grew 78%, and European
revenues declined 26% compared to 1998. In 1999, sales to one OEM customer
accounted for approximately 50% of the Company's revenue.

Gross Profit: Gross profit as a percentage of sales was 53% for the year
ended December 31, 2000, 47% for the year ended December 31, 1999 and 49%
for the year ended December 31, 1998. The increase in the gross profit rate
is primarily the result of a change in product mix and product cost
improvements that began in late 1999, whereby the Company improved its
purchasing and production processes.


Research and Development: The Company's investment in the development of
new products through research and development was $10.4 million, $10.6
million and $10.8 million in 2000, 1999, and 1998, respectively. As a
percentage of revenue, research and development expenses were 19%, 14% and
16% for 2000, 1999 and 1998, respectively. Research and development costs
decreased slightly in 2000, primarily due to a reduction in variable
spending in response to decreased revenues for the year. However, the
research and development investment in 2000 resulted in new products that
will provide the foundation for the Company's product lines in 2001 and
beyond.

Sales and Marketing: Sales and marketing expenses were $10.7 million, $11
million, and $10.1 million in 2000, 1999 and 1998, respectively. As a
percentage of revenue, sales and marketing expenses were 19%, 15% and 15%
for 2000, 1999 and 1998, respectively. The decrease in sales and marketing
expenses in 2000 is primarily the result of decreased revenues, which
resulted in reduced sales commissions and bonuses for the year, partially
offset by increased marketing activity used to position the Company for
future product releases.

General and Administrative: General and administrative expenses were $4.8
million, $5.4 million, and $5.4 million in 2000, 1999 and 1998,
respectively. As a percentage of revenue, general and administrative
expenses were 9%, 7% and 8% for 2000, 1999 and 1998, respectively. General
and administrative costs have been relatively consistent in recent years.
However, the decrease in 2000 costs, relative to 1999, is primarily due to
lower headcount related expenses, as the number of employees in the general
and administrative function decreased from 33 as of December 31, 1999 to 25
as of December 31, 2000.

Interest Income: Interest income was $1.2 million, $481,000 and $338,000 in
2000, 1999 and 1998, respectively. The increase in interest income from year
to year is a reflection of the increase in the funds available for
investment.

Interest Expense: Interest expense was $587,000, $694,000 and $1 million in
2000, 1999 and 1998, respectively. The decrease in interest expense is due
to the reduction of the Company's credit facility.

Other Expense, Net: Other expense, net, was $266,000, $817,000 and $896,000
in 2000, 1999 and 1998, respectively. Other expense primarily reflects the
amortization of goodwill and acquired developed technologies related to a
1996 acquisition of Synaptel. However, the net decrease in 2000 is
primarily due to the increase in other income generated by hedging
transactions on certain marketable securities received in the sale of the
Company's VOIP business. For the year ended December 31, 2000, these
hedging transactions resulted in a gain of approximately $689,000.

Provision for Income Taxes: The Company's provision for taxes was $1.7
million, $2.4 million and $2.2 million in 2000, 1999 and 1998, respectively.

The effective income tax rates were 42% in 2000, 36% in 1999 and 39% in
1998. The Company's effective tax rate is greater than the statutory rate
primarily due to nondeductible goodwill amortization. The increase in the
Company's effective income tax rate, from 1999 to 2000, is primarily due to
the decrease in foreign earnings, which are offset by foreign loss carry
forwards.


Discontinued Operations: In 1999, the Company sold its VOIP business for
$2.4 million. However, due to the uncertainty of payment on the proceeds
that remained unpaid as of December 31, 1999, the Company recognized income
upon payment. In 2000, the remaining $830,000 due for the technology
license fee was collected and recorded as a gain on disposal of discontinued
operations. Additionally, in 2000, the Company sold its 20% interest in
Quescom for $400,000, resulting in a gain of $91,000. The total gain in
2000 was $571,000 net of $350,000 tax. There were no operating activities
during 2000 related to the VOIP business. Gain on disposal of assets was
$326,000, net of tax, in 1999. Operating losses, net of tax, for the VOIP
business were $1.2 million and $829,000 for 1999 and 1998, respectively.

Net Income (Loss): The Company reported net income of $3 million in 2000,
$3.4 million in 1999 and $2.7 million in 1998.


LIQUIDITY AND CAPITAL RESOURCES

The Company's cash, cash equivalents and marketable securities aggregated
$17.5 million and $16.3 million at December 31, 2000 and 1999. The growth
in cash, cash equivalents and marketable securities from 1999 to 2000 is
primarily attributable to cash generated by the Company's operations,
proceeds received from the exercise of stock options and cash received in
connection with the sale of its VOIP business.

Expenditures for equipment and purchased software were $1.1 million, $2
million and $2.9 million in 2000, 1999 and 1998, respectively. At December
31, 2000, the Company had no material commitments to purchase capital
assets. The Company's significant long-term obligations are its operating
lease on its Dallas facility, future debt payments and repurchase of
Interphase common stock from Motorola (described below).

The Company has a $16 million credit facility with a financial institution.
This credit facility includes an $8.5 million term loan, a $2.5 million
equipment loan and a $5 million revolving credit facility. The term and
equipment loans are due in quarterly installments, and expire in November
2001. The revolving credit facility expires in June 2002. In 2001,
maturities of this credit facility will be approximately $1.7 million. The
Company has not paid any dividends since its inception and does not
anticipate paying any dividends in 2001.

Effective October 1998, the Company approved a stock repurchase agreement
with Motorola, Inc. to purchase ratably from October 1998 to July 2002, all
of the shares owned by Motorola for $4.1 million at $6.25 per share. Under
the terms of the agreement, Motorola retains the right as an equity owner
and has assigned its voting rights to the Company. The Company cancels the
stock upon each repurchase. Prior to the repurchase agreement, Motorola
owned approximately 12% of the Company's outstanding common stock. The
future scheduled payments are classified as redeemable common stock in the
accompanying consolidated balance sheets. As of December 31, 2000, 375,336
shares have been repurchased for $2.3 million and retired; 284,664 shares
remain to be repurchased.

The Company expects that its cash, cash equivalents, marketable securities
and proceeds from its credit facility will be adequate to meet foreseeable
needs for at least the next 12 months.

Recently Issued Accounting Pronouncements


On January 1, 2001, the Company adopted SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities," as amended by SFAS 137 and SFAS 138.
SFAS 133 requires all derivatives to be recorded at fair value. Changes in
the fair values of derivatives are recorded in either the statement of
operations or as a component of comprehensive income, depending on whether
the derivative qualifies as a hedge, and depending on the type of hedging
relationship that exists. Adoption of this standard did not have a material
effect on the Company's financial statements.""


ITEM 7a. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Foreign currency risk - Revenues originating outside of the United States
totaled 15%, 17% and 22% of total revenues in 2000, 1999, and 1998. Due to
the fact that the Company conducts business on a global basis in various
foreign currencies, it is exposed to adverse movements in foreign currency
exchange rates. During the periods presented, the Company entered into
certain foreign currency forward exchange contracts to reduce the risk of
foreign exchange exposure. Neither the foreign currency transaction gains
and losses nor the gains and losses on the forward contracts were
significant. The Company has not used, nor do they expect to use, forward
contracts for trading purposes.

Interest Rate Risk - The Company is exposed to interest rate risk under its
Credit Facility, which currently bears interest at 8.5%. The Company does
not enter into hedging arrangements to mitigate this risk.

Market Price Risk - The Company maintains a minority equity investment in a
publicly traded Company and recorded a $925,000 net after tax unrealized
loss during 2000 on this investment. The Company's ability to sell certain
equity positions is restricted under contractual arrangements. During 2000
the Company entered into a hedge on a portion of this equity investment,
realizing a gain of $689,000 on the transaction. The Company has no equity
hedge contracts outstanding as of December 31, 2000.

MANAGEMENT'S REPORT ON FINANCIAL RESPONSIBILITY


Management is responsible for the preparation and fairness of the
consolidated financial statements of Interphase Corporation and all other
information contained in this annual report. The accompanying consolidated
financial statements have been prepared in accordance with accounting
principles generally accepted in the United States and reflect informed
judgments and estimates, which management believes to be reasonable.

The Company maintains an effective system of internal accounting controls,
which are modified periodically as the Company's operations change.
Additionally, the Company is receptive to suggestions made by Arthur
Andersen LLP, its independent public accountants, regarding enhancements and
changes to the Company's existing internal accounting controls. Overall,
management believes that its system of internal accounting controls is
adequate to provide reasonable assurance as to the integrity and reliability
of its financial statements, and the safeguarding of assets.

The Board of Directors, acting through its Audit Committee, monitors the
accounting affairs of the Company and has approved the accompanying
consolidated financial statements. The Audit Committee, consisting of three

the actions taken by management in discharging its responsibilities for
accounting and financial reporting. The Audit Committee meets periodically
and privately with management and the independent public accountants to
assure that each is carrying out its responsibilities.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Shareholders and Board of Directors of Interphase Corporation:

We have audited the accompanying consolidated balance sheets of Interphase
Corporation (a Texas corporation) and subsidiaries as of December 31, 2000
and 1999, and the related consolidated statements of operations,
shareholders' equity, and cash flows for each of the three years in the
period ended December 31, 2000. These financial statements are the
responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Interphase Corporation
and subsidiaries as of December 31, 2000 and 1999, and the results of their
operations and their cash flows for each of the three years in the period
ended December 31, 2000, in conformity with accounting principles generally
accepted in the United States.

INTERPHASE CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation: The consolidated
financial statements include the financial statements of Interphase
Corporation (the "Company") and its wholly owned subsidiaries. All
significant intercompany accounts and transactions have been eliminated.

In September 1999, the Company completed the sale of its VOIP business.
Accordingly, the Company's consolidated financial statements and notes
included herein, for all periods presented reflect the VOIP business as a
discontinued operation in accordance with Accounting Principles Board
Opinion No. 30. See further discussion of the sale in Note 7.

Cash and Cash Equivalents: The Company considers cash and temporary
investments with original maturities of less than three months, as well as
interest bearing money market accounts, to be cash equivalents.

Investments - Investments in debt and equity securities are classified as
available for sale with unrealized holding gains and losses reported
in other comprehensive income. Management determines the appropriate
classification of securities at the time of purchase. Earnings from debt
securities are calculated on a yield to maturity basis and recorded in the
results of operations.


Allowance for doubtful accounts: As of December 31, 2000, 1999 and 1998,
the allowance for doubtful accounts was $273,000, $260,000 and $164,000.
The activity in this account was as follows (in thousands):

Balance at Write-offs Balance
Beginning Charged to Net of at End
Year Ended: of Period Expense Recoveries of Period
--------------------------------------------------------------------

December 31, 2000 $ 260 $ 358 $ (345) $ 273
December 31, 1999 164 120 (24) 260
December 31, 1998 544 392 (772) 164



Inventories: Inventories are valued at the lower of cost or market and
include material, labor and manufacturing overhead. Cost is determined on a
first-in, first-out basis (in thousands):


Years ended December 31,
2000 1999
-------------------------
Raw Materials $ 9,439 $ 8,044
Work-in-process 3,280 3,352
Finished Goods 474 282
------- -------
Total $ 13,193 $ 11,678
======= =======


Property and Equipment: Property and equipment are recorded at cost.
Depreciation and amortization are provided over the estimated useful lives
of depreciable assets using the straight-line method. When property and
equipment are sold or otherwise retired, the cost and accumulated
depreciation applicable to such assets are eliminated from the accounts, and
any resulting gain or loss is reflected in current operations. Related
depreciation expense and accumulated depreciation were as follows (in
thousands):

Year ended Depreciation Accumulated
December 31: Expense Depreciation
------------ ------- ------------
2000 $ 1,370 $ 9,755
1999 2,035 10,334
1998 2,436 10,339

The depreciable lives of property and equipment are as follows:

Machinery and equipment 3-5 years
Leasehold improvements 3-10 years
Furniture and fixtures 5-7 years

Capitalized Software: Capitalized software represents various software
licenses purchased by the Company and utilized in connection with the
Company's network and mass storage products as well as the general
operations of the Company. Capitalized software is amortized over 3-5 years
utilizing the straight-line method. Related amortization expense and
accumulated amortization were as follows (in thousands):

Year ended Amortization Accumulated
December 31: Expense Amortization
------------ ------- ------------
2000 $ 345 $ 2,139
1999 280 1,875
1998 302 1,656


Research and Development Subsidy: Included in other assets at December 31,
2000 and 1999, is a receivable for a subsidy of $72,000 and $529,000,
respectively, due from the French government related to the research and
development activities of the Company's Paris based operation.

Long-Lived Assets: Intangibles and other long-lived assets are reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. Any impairment would be recognized
in operating results if a permanent reduction in value were to occur.

Revenue Recognition: Revenues consist of product revenues and are
recognized in accordance with SEC Staff Accounting Bulletin (SAB) 101,
"Revenue Recognition." Product revenues are recognized upon shipment,
provided fees are fixed and determinable, a customer order is obtained, and
collection is probable. Revenues from reseller agreements are typically
recognized when the product is sold through to the end customer. Deferred
revenue consists of revenue from reseller arrangements and certain
arrangements with extended payment terms.


Concentration of Credit Risk: Financial instruments which potentially
expose the Company to concentrations of credit risk consist primarily of
trade accounts receivable. The majority of the Company's sales have been to
original equipment manufacturers of computer systems.

The Company conducts credit evaluations of its customers' financial
condition and limits the amount of trade credit extended when necessary.
The Company establishes an allowance for doubtful accounts based upon
factors surrounding the credit risk of specific customers, historical trends
and other information.

Research and Development: Research and development costs are charged to
expense as incurred.

Foreign Currency Translation: Assets and liabilities of certain non-U.S.
subsidiaries are translated at current exchange rates, and related revenues
and expenses are translated at average exchange rates in effect during the
period. Resulting translation adjustments are reflected in shareholders'
equity as a component of comprehensive income (loss).

Income Taxes: The Company determines its deferred taxes using the liability
method. Deferred tax assets and liabilities are based on the estimated
future tax effects of differences between the financial statement and tax
basis of assets and liabilities given the provisions of enacted tax law.
The Company's consolidated financial statements include deferred income
taxes arising from the recognition of revenues and expenses in different
periods for income tax and financial reporting purposes.

Certain Reclassifications: Certain prior year amounts have been
reclassified to conform with the 2000 presentation.

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



2. ACQUISITION

As a result of the acquisition of Synaptel, S.A. ("Synaptel") and certain
product rights acquired from Cisco Systems, Inc. ("Cisco"), the Company
acquired intangible assets related to developed technologies, assembled
workforce and goodwill. Developed technology and assembled workforce are
amortized on a straight-line basis over a 7-year period. Goodwill is
amortized on a straight-line basis over a 15-year period. Acquired product
rights from Cisco are amortized ratably over the anticipated revenue stream
of such products sold. The December 31, 2000 intangible balances at
historical cost and related amortization expense and accumulated
amortization were as follows (in thousands):



Amortization Expense Accumulated Ending
Intangibles 2000 1999 1998 Amortization Balance

Acquired Product
Rights-Cisco 2,500 - 485 435 2,500 -




3. MARKETABLE SECURITIES

Marketable securities consist of investments in equity and debt securities.
As of December 31, 2000 and 1999, the fair market value of marketable
securities was $6.9 million and $5.3 million, respectively. During 2000,
the Company realized a gain of $689,000 from the sale of securities. The
Company had an unrealized loss of $887,000 (net of taxes) in 2000, and an
unrealized gain of $692,000 (net of taxes) in 1999, with respect to certain
available-for-sale securities.


4. DERIVATIVES AND HEDGINGS

The Company addresses certain financial exposures through a controlled
program of risk management that includes the use of derivative financial
instruments on a minimal basis. The Company does not utilize or expect to
utilize derivative financial instruments for trading or speculative
purposes.

During the periods presented, the Company entered into certain foreign
currency forward exchange contracts to reduce the risk of foreign exchange
exposure. Neither the foreign currency transaction gains and losses nor the
gains and losses on the forward contracts were significant. Additionally,
the Company entered into a hedge on a portion of an equity investment
realizing a gain of $689,000 on the transaction. The Company has no equity
hedge contracts outstanding as of December 31, 2000.


On January 1, 2001, the Company adopted SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities," as amended by SFAS 137 and SFAS 138.
SFAS 133 requires all derivatives to be recorded at fair value. Changes in
the fair values of derivatives are recorded in either the statement of
operations or as a component of comprehensive income, depending on whether
the derivative qualifies as a hedge, and depending on the type of hedging
relationship that exists. Adoption of this standard did not have a material
effect on the Company's financial statements.


5. ACCRUED LIABILITIES

Accrued liabilities consisted of the following (in thousands):

Years ended December 31,
2000 1999
-----------------------
Accrued outside commissions $ 300 $ 362

Accrued other 2,235 1,077
------ ------
$ 2,816 $ 1,586
====== ======


6. CREDIT FACILITY

The Company maintains a credit facility with a bank. The credit facility
consists of an $8.5 million acquisition term loan, a $2.5 million equipment
financing facility and a $5 million revolving credit facility. The
revolving credit facility matures June 30, 2002, and bears interest at the
bank's base rate (currently 8.5%). The term loan and equipment loan are
payable in equal quarterly installments totaling $548,000 plus accrued
interest with final payment due November 30, 2001. The Company has the
ability to satisfy the quarterly payments on the term notes through
borrowing under the revolving credit component of the credit facility. The
credit facility is collateralized by marketable securities, accounts
receivable and equipment. The credit facility includes certain restrictive
financial covenants including, among others, tangible net worth, total
liabilities to tangible net worth, interest coverage, quick ratio, debt
service coverage, and is subject to a borrowing base calculation. At
December 31, 2000, the Company was in compliance with all covenants. At
December 31, 2000, total availability under the revolving credit facility
was $1.5 million.



At December 31, 2000 and 1999, the Company's outstanding debt consisted of
the following (in thousands):
Year ended December 31,

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



The total scheduled debt principal payments are $1.7 million in 2001, $3.5
million in 2002 and zero thereafter.



7. DISPOSITION OF ASSETS

In June 1999, the Company sold an 80% interest in part of its VOIP business,
Quescom, for $1,172,000 to the former owner of Interphase's Paris Operation.
The sales proceeds consisted of $300,000 due at closing with a $830,000
technology license fee. In 2000, the remaining $830,000 due for the
technology license fee was collected and recorded as a gain on disposal of
discontinued operations. Additionally, in 2000, the Company sold its 20%
interest in Quescom for $400,000, resulting in a gain of $91,000. The total
gain in 2000 was $571,000 net of $350,000 tax.

In September 1999, the Company sold its other VOIP business, Zirca
Corporation ("Zirca"), along with the technologies developed by Zirca for
$300,000 cash and stock valued at $517,680 on the date of disposition, to
UniView Technologies, resulting in a gain of $140,000, net of $86,000 tax.
The UniView securities received as part of the agreement are included on the
Balance Sheet in Marketable Securities, and accounted for as available-for-
sale securities.

The Company has not recorded a valuation allowance with respect to the
various domestic deferred tax assets, as management believes it is more
likely than not that these assets will be realized. Management periodically
reviews the realizability of the Company's deferred tax assets, as
appropriate, when existing conditions change the probability of realization.

10. COMMON STOCK

Amended and Restated Stock Option Plan: In 2000, the Company amended and
restated its Stock Option Plan which, as amended, authorizes the issuance to
employees of up to 3,500,000 shares of common stock in incentive stock
options (as defined in section 422 of the Internal Revenue Code of 1986, as
amended) and nonqualified stock options. The exercise price of the
incentive stock options must be at least equal to the fair market value of
the Company's common stock on the date of the grant, while the exercise
price of nonqualified stock options may be less than fair market value on
the date of grant, as determined by the Board. The Board may provide for
the exercise of options in installments and upon such terms, conditions and
restrictions as it may determine. Options granted prior to January 1, 1999
generally vest ratably over a 5-year period from the date of grant. Options
granted since January 1, 1999 generally vest ratably over a 3-year period
from the date of grant. The term of option grants may be up to 10 years.
Options are canceled upon the lapse of three months following termination of
employment except in the event of death or disability, as defined.

United Kingdom Stock Option Sub-Plan: This plan was adopted in 1988 for the

Rights Agreement: The Board of Directors has adopted a Shareholder Rights
Plan whereby each holder of record as of December 29, 2000 received a right
to purchase from the Company one share of common stock of the Company at a
price of $93 per share for each share held. These rights can only be
exercised after certain events occur, such as if a person or entity
acquires, or makes a tender or exchange offer to acquire, 15% or more of the
Company's common stock and the rights expire ten years from the record date.
Upon acquisition of 15% or more of the Company's common stock, each right
not owned by the acquiring person or group will be adjusted to allow the
purchase for $93 of a number of shares having a then market value of $186.
These rights are intended to provide the Company certain antitakeover
protections. The Board of Directors may terminate the Rights Plan, or
redeem the rights for $0.01 per right, at any time until the tenth business
day following a public announcement of a 15% or more stock acquisition. The
Company had reserved 7,000,000 shares of common stock for this plan.

The rights were distributed to shareholders as of the record date as a non-
taxable dividend. The rights are attached to and trade with Interphase
common stock until the occurrence of one of the triggering events, at which
time the rights would become detached from the Company's common stock.

Pro-Forma Net Income (Loss): The Company's pro forma net income (loss) for
2000, 1999 and 1998 would have been $ (2.2 million), $1.5 million and $1.6
million respectively, resulting in diluted earnings per share of $(0.36),
$0.24 and $0.29, respectively. 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 options granted in
2000, 1999 and 1998: risk-free interest rate of 6% for each year 2000, 1999
and 1998, expected dividend yield of zero in each year, expected term of
3.88 in 2000, 4.83 years in 1999 and 4.41 years in 1998, and expected
volatility of 140% in 2000, 140.29% in 1999 and 117.31% in 1998. The
weighted average fair valuation per share was $12.63 in 2000, $14.25 in 1999
and $5.42 in 1998.

Because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro-forma
compensation cost may not be representative of that to be expected in future
years.


11. RELATED-PARTY TRANSACTIONS

The Company paid approximately $253,000, $366,000 and $425,000 for the years

with Motorola, Inc. to purchase all of the shares owned by Motorola for $4.1
million or $6.25 per share, ratably from October 1998 to July 2002. Under
the terms of the agreement, Motorola retains the right as an equity owner
and has assigned its voting rights to the Company. The Company cancels the
stock upon each purchase. The future scheduled payments are classified as
redeemable common stock in the accompanying consolidated Balance Sheet. As
of December 31, 2000, 375,336 shares have been purchased for $2.3 million
and retired.


13. EMPLOYEE BENEFIT PLAN

meet the plan's length of service requirements. Under the defined
contribution plan, employees may make voluntary contributions to the plan,
subject to certain limitations, and the Company matches employee's
contributions up to 3% of the employees' annual salary. The total expense
under this plan was $256,000, $232,000 and $240,000 for the years ended
