RANSOM LOVE:

         I welcome everyone to the Caldera Systems fourth quarter and fiscal
year 2000 call today, and thank you for joining us.

         While the company has continued its activities across several fronts,
including product development and education curriculum offerings, the primary
focus of


   2

management has been the consummation of the acquisition announced early in the
fourth quarter. As I'm sure you're aware, Caldera Systems and The Santa Cruz
Operation have reached a definitive agreement whereby Caldera will acquire SCO's
Server Software Division and Professional Services Division. This matter is now
in the S.E.C. process. We expect the S.E.C. will complete their final review
before the end of the year. Optimistically, we are then expecting to send out
proxy materials by early January, 2001. We anticipate that shareholders will
approve the acquisition, thereby allowing us to consummate the acquisition
during the latter part of February, 2001.

         I will reiterate that this acquisition is literally an
industry-changing event, vaulting Caldera into a global distribution presence
through more than 22,000 partners worldwide. With the acquisition, Caldera
International will have the largest reseller channel with UNIX/Linux skills in
the industry.

         We have been briefing SCO customers, partners, and channel partners
worldwide, and have had excellent feedback and response. We have recently begun
a global 40-city tour and have experienced record attendance consistently in
every city visited thus far.

         As we have briefed SCO customers such as McDonald's, BMW, and Deutch
Bahn, they enthusiastically endorse the technology base, and have agreed to
maintain their commitment to Caldera International. This education process with
customers and partners insures that Caldera International will acquire vibrant
and dynamic SCO divisions as we carry long-existing relationships with us into
the future. Although we are currently bearing the cost burden of this affiliate
education process as a stand-alone entity and the benefits of our efforts may
first be felt by the SCO Divisions, the results will ultimately accrue to the
Linux operations as well since synergies will mount for the combined group.

         In addition, the response from our strategic partners has been
outstanding. As a result of the acquisition, Compaq has indicated that Caldera
International (which is the new combined company following the acquisition) will
be its premier Linux/UNIX provider. Although both Caldera and SCO had
independent relationships with Compaq prior to the acquisition announcement, the
combination of the two companies is viewed as positive--even synergistic--by
Compaq and indeed strengthens the overall relationship. Since the acquisition
announcement, we have concluded a transaction that will make Caldera Linux
available on the full Proliant server line. The current plan is to formally
announce preload availability in January, 2001. Separately, Caldera will
promote/sell advanced clustering solutions that have been jointly developed by
both Caldera and SCO. Compaq and Caldera are engaging in joint sales
opportunities worldwide, and our future as partners looks bright.

         Caldera and SCO have already begun to join forces to produce
industry-evolving products. Caldera has been collaborating on the development of
the Linux kernel personality with the current SCO engineers in order to allow
Linux applications to run on a UNIX kernel. Oracle has run its full suite of
Linux certification tests and found it to be 100 percent compatible with Linux.
Caldera International expects to be able to release a



   3


platform that is Linux Standard Base and UNIX 98 compliant in the first quarter
of 2001. We will be the only alternative platform that scales from the client to
the enterprise on high volume hardware. The utilization of the Linux and Unix
platforms in concert provides users with robustness and scalability unavailable
elsewhere in the industry.

         I will summarize for you some of the other achievements the company has
made during this fourth quarter:

         We are in the final phase of successful open beta testing of our new
Linux management solution, Caldera Volution, which is a browser- and directory-
based management product for Linux systems. Using Volution, network
administrators can create policies and profiles to manage a half dozen or
thousands of Linux systems, without having to individually manage or touch each.
By consolidating management functions for labor-intensive tasks, Volution
dramatically reduces costs, saves time, and increases job efficiency. Initial
response to Volution has been very positive. The product will ship the first
week of January, 2001.

         IDC shows the market opportunity for management in our space to be $7
billion with Linux currently the number two OS platform. In addition, we believe
Caldera has a six-to-twelve-month lead on providing such a comprehensive
offering. Caldera will also be able to roll this out to the impressive installed
base of SCO customers which is the largest base of UNIX customers.

         Our education initiative has continued to advance. In October we
announced that the first three courses for our OpenLinux Solution Series are
complete. Three additional courses will be available before the end of the
calendar year 2000. The OpenLinux Solutions Series is designed to educate IT
professionals to deploy and manage specialized servers.

         A change in our management team has occurred with the recent addition
of Bob Bench as our Chief Financial Officer. Bob has over 27 years experience in
various senior executive positions including President, Chief Financial Officer,
and Chief Operating Officer. His business background includes IT services,
Computer Software, Computer Hardware, Semiconductors, Investment Banking, and an
international assignment in Business Development. With the wealth of experience
he brings, we are understandably happy to welcome him to Caldera Systems.

         I'll now turn the call over to Bob to discuss in more detail our
financial performance.

BOB BENCH:

         Thank you. I am pleased to announce that fourth quarter revenue for
Caldera Systems was $1.2 million, an increase of 34 percent over the same period
in the prior fiscal year, and a decrease of 1 percent from the third quarter of
fiscal 2000. Revenue for


   4


fiscal 2000 was $4.3 million compared to $3.1 million for fiscal 1999, an
increase of 38 percent.

         For fiscal year 2000, the net loss is $39.2 million or $(1.19) per
common share compared to a net loss of $9.4 million or $(0.51) per common share
in 1999. This increase in net loss represents the costs associated with a large
ramp up of worldwide operations, an increase in employees, our commitment to
developing Linux-based business solutions, and a substantial increase in
marketing.

         The net loss for the fourth quarter was $6.9 million or $(0.18) per
share versus a net loss of $4.5 million or $(0.17) per share in the same period
in the prior fiscal year and and net loss of $7.5 million or $(0.19) per share
in the third quarter of 2000.

         Revenue for the fourth quarter was split between software revenue and
service revenue.

         Our operating expenses for the quarter were $9.9 million comprised of
the following components:

         (1). Sales and marketing expenses of $4.3 million reflecting our
aggressive worldwide marketing and brand-building strategy.

         (2). Research and development expenses were $1.6 million, which was
also according to plan. This reflects the company's commitment to world-class
products and the aggressive introduction of new products.

         (3). General and administrative expenses were $1.9 million. This is
reflective of our ramp up in anticipation of closing the acquisition of the SCO
Divisions.

         (4). Amortization of deferred compensation was $1.2 million which was
higher than anticipated as a result of option modifications made during the
quarter.

         (5). A one-time, cost-sharing charge relating to the SCO acquisition of
$0.9 million. This relates to our agreement to retain a vibrant, worldwide sales
and service organization in anticipation of the completion of the SCO
acquisition. We will record the additional $600 thousand of the agreed-upon $1.5
million total cost-sharing charge during the first quarter of fiscal 2001.

         Other income of $3.4 million included $1.1 million of interest income
earned on cash balances, and a one-time gain of $2.3 million recognized on the
sale of certain non-strategic assets and intellectual property.

         Excluding the effects of the non-recurring charge to the Santa Cruz
Operation and the gain from the sale of the Electronic Linux Marketplace assets,
the net loss to common shareholders would have been ($0.21) per common share for
the fourth quarter of 2000.

         Our strong balance sheet reflects total cash and marketable securities
of $90.7 million, placing us in an extremely favorable position from which to
drive growth. We received a $15 million cash infusion during the quarter from
the sale of 40 percent of our holdings in Lineo, Inc. This strong cash position
will contribute to our capacity for rapid growth as we absorb the planned
acquisition of the two SCO Divisions.



   5

         Looking forward, we anticipate that in our next several quarters were
we a stand-alone company, our operating expenses would be similar to our most
recent quarterly trends. Upon completion of the SCO transaction, we will again
address our projections.

         Two strategic initiatives will impact revenues as we transition the
company:

         (1). Currently, most of our software revenue is coming from retail
sales. Strategically, we are moving to a more economical model of Business to
Business including corporate and OEM partnerships and strategic alliances. We
foresee this impacting our revenues for the next several quarters as retail
sales drop more rapidly than the ramp up of corporate sales. Corporate sales are
growing as we anticipated and we expect corporate and OEM sales to surpass
retail sales by the end of the second quarter of fiscal year 2001 returning us
to consecutive quarterly revenue growth trend.

         (2). Our focused attention on completing the acquisition of the two SCO
Divisions will also impact revenues since the magnitude of the transaction
itself demands a commensurate proportion of the time and resources of
management.

         Both of these initiatives are strategic decisions we have made to
position Caldera as the leading provider of e-based computing solutions.

         We will now be happy to answer any questions you may have. We do
request that you ask just one question for the first round, please. If time
permits we will return to you for additional questions. Thank you.

These statements are not guarantees of future performance and actual results
could differ materially from current expectations. Factors that could cause or
contribute to such differences include, but are not limited to 1) the potential
disruption of Caldera's and SCO's businesses that might result from employee or
customer uncertainty, and lack of focus following announcement of the
Acquisition in connection with integrating the operations of Caldera and SCO; 2)
product integration risk due to overlapping products and technologies; 3) the
possibility that the Acquisition might not be consummated; 4) the effects of the
public announcement of the Acquisition on Caldera's and SCO's stock prices,
their sales and operating results, their ability to attract and retain key
personnel and the progress of certain of their development projects; 5) the risk
that the announcement of the Acquisition could result in decisions by customers
to defer purchases of products of Caldera or SCO; 6) the risk that redundancy in
staffing and infrastructure could reduce efficiency and increase costs; 7) the
difficulties of managing geographically dispersed operations; and 8) the risk
that other benefits sought to be achieved by the Acquisition will not be
achieved. These and other factors are risks associated with Caldera's and SCO's
businesses that may affect their operating results and are discussed in SCO's
