  ITEM 1.      BUSINESS

  Sequoia Systems, Inc. ("Sequoia" or the "Company") designs, manufactures and
markets differentiated computer systems, servers, microcomputers and central
processor unit ("CPU") boards for critical information processing environments
that require the highest degree of data reliability and availability.  These
products are based on industry standard components from the Intel Corporation
("Intel"), Sun Microsystems, Inc. and Motorola Inc., with Sequoia-developed
technology added to provide fault tolerance and ruggedness as required by the
application or user environment.  The Company supports its customers with a full
range of services, including professional services and hardware and software
maintenance support.

  On March 31, 1995, the Company completed a merger and stock purchase pursuant
to which the Company acquired all of the common stock of SPCO, Inc., along with
its subsidiaries Texas Microsystems, Inc. and Texas Micro Electronics, Inc. and
their respective subsidiaries ("the TMI Group"). The Company issued 5,272,944
shares of its common stock in exchange for all the common stock and securities
to acquire the common stock of each of the members of the TMI Group. The
Transaction has been accounted for as a pooling of interests, and accordingly,
the consolidated financial statements for all comparative periods have been
restated to include the results of operations, the financial position and cash
flows of the TMI Group.

  Sequoia was incorporated in Delaware in September, 1981.  Sequoia's principal
executive offices are located at 400 Nickerson Road, Marlborough, Massachusetts
01752.  The Company's telephone number is (508) 480-0800.


  Industry Background

  In January 1995, the Standish Group, an industry research organization,
published a report on the need for computer system availability within MIS
operations in the United States.  Their results stated that the "... demand for
around the clock IT (information technology) operations is being fueled by the
need to meet customer requirements and meet or beat the competition."

  According to the Standish Group survey, 12.1% of Enterprise applications
currently run 24 hours a day.  This proportion will increase two fold by 1996 to
24.9%.  Nearly one-third of these applications will require almost constant
availability, i.e., a maximum allowable downtime of 0 to 3 seconds in any given
day.

                                       3

  Many of these computers must also operate in unusual environments -- somewhere
other than a desktop or a computer room. Today, computers are being used more
frequently in field environments and on factory floors -- places where
information is increasingly being put into digitized form onto computers.  The
need to quickly and accurately process information in these environments is
often no less pressing than within a traditional corporate MIS environment.
Therefore, the computers used in the field and on the factory floor must be
environmentally rugged enough to withstand the conditions that typically exist
in these environments  --  greater extremes of vibration, temperature, dust,
humidity, etc.

  Accordingly, the Company believes that continuous system availability and data
integrity is an increasingly important requirement to business enterprises of
all sizes.  Sequoia meets this need with fault-tolerant and high availability
products and ruggedized microcomputers.


  Company Strategy

  Sequoia operates in the computer hardware segment of the industry, while
specifically addressing expanding market requirements for greater system
availability.  Sequoia provides Motorola-based and Intel-based systems and
upgrade products for the on-line transaction processing market ("OLTP") and for
interactive computing environments.  With the acquisition of Texas Microsystems,
Inc., Sequoia's expanded business lines also include ruggedized, mission-
critical computers, both SPARC and Intel-based, for the industrial market, as
well as Bellcore Network Equipment Building Specifications ("NEBS") compliant
products specifically designed for the telecommunications market.  Sequoia also
makes its open systems technology available to global partners through licensing
agreements.  The objective of these licensing agreements is to take advantage of
the greater research and development capabilities of such partners to produce
expanded features that can broaden the market for Sequoia's computer products.

  Sequoia's business strategy incorporates the following key elements:

  Product Differentiation
  -----------------------

  Sequoia differentiates its products from commercial computers marketed by
larger competitors by focusing on market niches where highly available hardware
is required to meet the more rigorous demands of the application.  Sequoia has
applied fault-tolerant and ruggedization strategies to systems and desktop
personal computers ("PC"s) and has adapted SPARC workstations and PC's to the
NEBS central office telecommunications environment.

                                       4
<PAGE>
 
  Focus on Targeted Vertical Markets
  ----------------------------------

  Sequoia has focused on a limited number of vertical markets. In particular,
Sequoia has developed strong customer relationships through both Value Added
Reseller ("VAR") and Original Equipment Manufacturer ("OEM") channels in the
telecommunications, industrial, health care claims processing, retail
distribution and financial services markets.

  Technology Licensing and Strategic Partnerships
  -----------------------------------------------

  Sequoia licenses its patented fault-tolerant technology to companies in
computer-related industries. Prospective candidates for the licensing of
Sequoia's technology are companies that desire or need greater reliability in
their computer-related hardware or software products. These companies recognize
that a growing number of their customers depend on their products for continuous
access to accurate information. Sequoia's current licensing arrangements include
Toshiba Corporation, Samsung Electronics Co., Ltd. and Novell, Inc. Sequoia
intends to seek opportunities to form additional strategic alliances, including
potential acquisitions.

  Customer Support, Training and Professional Services
  ----------------------------------------------------

  Sequoia's Customer Service Operation has a 24-hour, seven-day a week,
worldwide telemaintenance and support capability whereby customer Enterprise
systems are continuously monitored by various support systems. Technical support
operations also provide telephone troubleshooting service for end user customers
and distributors.  Sequoia offers a broad array of training and other
professional services to assist its customers in maximizing the return on their
investment in Sequoia's products.


  Products

  Sequoia develops, markets, sells, manufactures, and services systems that meet
critical business requirements for Enterprise computing.  Sequoia also provides
ruggedized microcomputers and components that can withstand harsh conditions.
Today's products range from ruggedized microcomputers and components, primarily
Intel and SPARC-based, to larger Enterprise systems that are migrating from
Motorola 68040-based to Intel-based microprocessors. In fiscal 1996, Sequoia
will begin offering Intel-based, highly available Enterprise systems which are
designed to recover quickly from failures with a minimum loss of data.

  Enterprise Server Products
  --------------------------

  Sequoia's fault-tolerant and highly available systems are based on industry-
standard technologies combined with patented fault-tolerant techniques to
address the needs of the OLTP market. The requirement for immediate access to
data created the market for OLTP systems.  In order to address the needs of a
distributed computing environment, Sequoia is expanding its product line to
newer technologies based on Intel microprocessors. Intel-based Enterprise
systems, which can be used as a server in a client/server distributed 

                                       5
<PAGE>
 
computing network, will allow Sequoia to provide industry-standard products
compatible with all major databases and software applications, increasing
Sequoia's market opportunities. Sequoia's Enterprise systems include the
following features:

  Industry-Standard Compatibility
  -------------------------------

  By using industry-standard components (such as Motorola and Intel
microprocessors), operating systems (UNIX), database technologies (Pick),
communications and peripheral devices and protocols (X.25, Ethernet), Sequoia's
systems can be integrated easily into a wide variety of computing environments
and can support new technologies and services without significant system
redesign.

  System Architecture, Modularity and Expandability
  -------------------------------------------------

  The architecture of Sequoia's fault-tolerant systems is designed to provide
the user with continuous and reliable computer availability and to address the
high performance requirements of computer-intensive, on-line applications.
Sequoia's Series 500 and 440 systems achieve fault tolerance and high
performance with a tightly coupled symmetric multiprocessing architecture
consisting of multiple processors that share memory and are managed by a single
operating system, based on UNIX.  Through this design, tasks are automatically
and efficiently distributed over all available processors, which allows the
Sequoia platform to support a large number of users.  The Sequoia architecture
enables customers to expand incrementally the processing power and capacity of
their systems by adding processors, memory elements and peripheral devices as
needed. Sequoia's Intel-based systems can also be tailored to handle a large
number of users, simply by adding the appropriate disk capacity, memory and
terminals.

  Data Integrity
  --------------

  Sequoia's Series 500 and 440 fault-tolerant hardware design, coupled with
Sequoia's UNIX-compatible operating environment are designed to provide
continuous system availability and data integrity.  If a hardware fault is
detected, the faulty module is automatically taken out of service and the
operating system returns the system to normal operations without loss of data or
program continuity.  If the error was due to a transient fault, the module is
returned to service.  The detection, isolation and correction of the fault all
occur automatically without requiring the user's intervention.

  Operating Systems
  -----------------

  Sequoia's Series 500 and 440 are Motorola-based products based on TOPIX,
Sequoia's proprietary version of the UNIX operating system. Although UNIX was
originally developed to work with standard uniprocessor systems, Sequoia
designed TOPIX for high-performance OLTP applications in a symmetric
multiprocessor fault-tolerant environment, while still adhering to the industry
standards defined for UNIX.  Sequoia's SES100/110 Intel-based products will run
in SEQUOIApro, a native Pick mode operating environment.

                                       6
<PAGE>
 
  Product Line Models
  -------------------

  Sequoia's current computer system product lines include the fault-tolerant
Motorola-based Series 440, Series 500 and the high reliability Intel-based
Sequoia Enterprise Servers, models 100 and 110. In a fault-tolerant system, all
faults are detected, isolated and fully recovered, transparent to the end-user
applications.  Faults can range from transient power fluctuations to hardware
component failures; data storage device outages to communications line errors;
known software 'panics' to transient error conditions within the operating
system.  A fault-tolerant system will protect the end-user from an interruption
in application processing.. Sequoia currently addresses high reliability by
engineering robust systems with higher mean-time-between-failure ("MTBF")
characteristics and lower mean-time-to-repair ("MTTR") features.

  The Series 440 system is the successor to Sequoia's Series 100, Series 200,
Series 300 and Series 400 systems.  The Series 440 is a complete computer system
consisting of electronics, peripherals, communications interfaces and system
software.  The Series 440 is based on the Motorola 68040 microprocessor.  The
Series 500, a successor of the S40, and also based on the Motorola 68040
microprocessor, offers a lower priced entry to fault-tolerant systems, as well
as a number of new operating features.

  The Sequoia Enterprise Server SES/100, Intel-based, is a mini-tower computer
designed to maintain high reliability for critical applications.  It contains a
passive back-plane, allowing easy enhancements to the system performance and
upgradability.  The Sequoia Enterprise Server SES/110 tower computer, also
Intel-based, provides greater expansion capabilities over the SES/100.  It is
intended for  those sites requiring large disk capacity and flexibility in
peripheral selection.

  The end-user list price of a Series 440 ranges from approximately $300,000 to
more than $5,000,000, depending upon the configuration.  The Series 500 base
configuration starts at $86,000. The Sequoia Enterprise Servers, SES/100 and
SES/110, range from an entry level average list price of $17,500 to $70,000 at
the high end of the configuration. Sequoia typically offers discounts from its
list prices to resellers and customer in order to meet competitive conditions.


  Ruggedized Products
  --------------------

  Sequoia focuses its ruggedized products on critical applications in the
industrial and telecommunications markets. Characterized by rigorous
environments and the need for unattended, uninterrupted operations, Sequoia's
Intel and SPARC based microcomputers are designed to withstand wide temperature
ranges, shock, vibration, dirty air, moisture and electromagnetic and radio
frequency interference ("EMI/RFI").  Sequoia has adapted SPARC technology that
is NEBS compliant and is the leading supplier of SPARC based products to the
telephone central office  industry.  Sequoia has also developed ruggedized
mobile and vehicle mounted computers and has broadened its market opportunities
by 

                                       7
<PAGE>
 
developing a range of fault-tolerant features for the PC.  These ruggedized
products platforms feature:

  Industry Standard Compatibility
  -------------------------------

  The Company's passive backplane PC's are fully compatible with standard PC
operating systems, peripherals and application software.  SPARC based products
are also fully compliant with Sun Microsystems operating systems and
peripherals.

  Modularity
  ----------

  The Intel-based passive backplane systems provide for much greater
expandability than the generic motherboard.  These systems can be configured
with from 5 to 20 expansion slots depending on chassis selection, with a wide
range of supporting peripherals.

  Scaleable Growth
  ----------------

  Ruggedized products are available in industry standard rackmount configuration
with many options such as expansion chassis and disk farms.  Typical customers
will employ multiple rackmounted systems in a configuration where scalability is
achieved by adding additional modules as needed.

  High Reliability
  -----------------

  Sequoia addresses high reliability and availability by engineering robust
systems with higher mean-time-between-failure ("MTBF") characteristics and lower
mean-time-to-repair ("MTTR") features.  The Company is currently developing
technology that will provide sub-second failover capability to the ruggedized
microcomputer platform.

  Product Line Models
  -------------------

  Sequoia manufactures a broad line of ruggedized PC compatible products,
including rackmount system platforms and boards, for use in data acquisition,
process control, embedded control, and other applications requiring resistance
to shock, temperature extremes, dust, or humidity.

  Ruggedized system products for the industrial markets consist primarily of
rackmount platforms which offer different combinations of expansion slots, disk
capacity, alarming capability, power options, and a choice of processors.
Systems may also include various video, I/O, or communication expansion cards
which are sourced from outside vendors. These products are offered at a wide
range of price points depending on configurations.

  Rackmount platforms are also specially designed for the telecommunications
marketplace.  The 9610 and 9620 families are based on SPARC based boards
purchased from SUN Microsystems.  These platforms are designed and tested to
stringent NEBS specifications required for installation into telephone central
office facilities, and are often 

                                       8
<PAGE>
 
attached to telephone 'switches' as Intelligent Peripherals. These platforms
sell at prices from $12,000 to $80,000 depending on CPU speed, memory, and
storage configuration.

  Board level products include 386, 486, and Pentium based CPUs, with new
generations to be introduced in the future.  These CPUs are embedded into
manufactured system products and are also sold as components to be integrated
into specialized platforms by customers.  Depending on specifications, these
board level products sell at prices from $300 to $2500.

  On February 1, 1995, the Company acquired certain assets of Intel related to
Intel's OmniRACK and XpressRACK product lines. These systems are usually
configured with either manufactured system boards or  motherboards purchased
from Intel.


  Marketing, Sales and Customers

  Through June 30, 1995, Sequoia has collectively shipped more than 370
Enterprise level systems and 110,000 PC based systems or complements of chassis
and CPU boards, with additional components such as memory boards and processor
expansion units, to more than 5,000 customers worldwide.

  In recent years, for the Enterprise systems Motorola-based product line,
Sequoia has focused its sales and marketing efforts in three primary markets:
(i) health maintenance organizations which typically use Sequoia systems for
administrative services;  (ii) retail wholesalers and telemarketers which use
Sequoia  systems to support order processing and inventory control requirements;
and (iii) financial services organizations which typically use Sequoia systems
for customer applications such as credit card or mortgage processing.

  The Company's ruggedized products primarily serve two markets: industrial and
telecommunications. In these markets, the products are most frequently used in
"mission-critical" or "job-critical" applications where reliability,
availability and/or data integrity are essential to the enterprise. Sequoia
believes that the growing need for extremely dependable microcomputers will make
"mission-critical" applications one of the most rapidly expanding sectors of the
microcomputer industry.

  For the industrial PC market, Sequoia provides microcomputers that operate
reliably in harsh industrial environments, allowing them a significant role in
process control, discrete manufacturing and data acquisition. The systems and
board-level products are used in applications that often have government-
mandated requirements for up-to-the-minute reporting of data, such as
environmental safety information, financial data or transit monitoring.

                                       9
<PAGE>
 
  For the telecommunications market, the central office environment has very
rigorous standards for operating equipment. Telecommunications computer systems
in the U. S. must be NEBS compliant including 48-volt power, heat and dust
protection, earthquake resistance, alarming and remote monitoring features.
Because of its experience in designing and building reliable rack-mounted
systems that operate under harsh conditions, Sequoia believes that the
telecommunications industry presents significant opportunities for its products.

  The markets for NEBS compliant SPARC and Intel based products and ruggedized
Intel based products are characterized by rapidly changing technology and user
needs, requiring significant investment for product development.  Sequoia
believes that part of its success in the future will depend upon its ability to
develop, manufacture and market products which meet changing user needs in these
markets and which successfully respond to technological changes in architectural
standards in a cost-effective and timely basis.

  Sequoia markets its products through a combination of its direct sales
organization, distributors, Value Added Resellers (VAR's)/ Value Added
Distributors (VAD's), System Integrators (SI's), and Original Equipment
Manufacturers (OEM's).

  VAR's generally package Sequoia Enterprise Servers with other hardware or
applications programs for resale to end-users.  Sequoia generally appoints VAR's
and resellers which target particular applications or vertical markets, or cover
certain geographies.  At the end of fiscal 1995, over 25 VAR's Enterprise server
products  and over 1,000 resellers were under contract to sell ruggedized
products.

  Internationally, Sequoia sells through a combination of direct sales and
distributors.  Sequoia has approximately 40 distributors in over 25 countries
including the United Kingdom, the Netherlands, Germany, Israel and Australia.

  During fiscal 1995, sales to one customer, DSC Communications Corporation,
represented 13% of total revenues.  For the previous fiscal year, there were no
sales to any customer that represented over 10% of total revenues.  The Company
believes that certain VAR's in the healthcare market and a select number of
customers in the telecommunications market will continue to represent a
substantial portion of overall sales.  Changes in Sequoia's relationship with,
performance by or loss of such customers could have a significant effect on the
Company's revenues and operating results.

                                      10
<PAGE>
 
  Competition

  Competitors of Sequoia vary among the products offered by the Company.
Sequoia's Enterprise Systems and fault-tolerant products compete in the 10 to
2,000-plus user range of the on-line transaction processing, open systems
market.  Sequoia therefore competes against other fault-tolerant companies and
against a wide range of open systems non fault-tolerant companies which market
their products as achieving high availability.  The majority of Sequoia's
customers for the Enterprise Server business use the Pick database. For fault
tolerant  products, Sequoia's primary competitors are Tandem Computers
Incorporated and Stratus Computer, Inc.  Sequoia believes that it competes
effectively in the fault-tolerant market on the basis of its system
architecture, price/performance attributes, its version of the UNIX operating
system and use of industry standard hardware and software.  In the broader
general purpose non fault-tolerant marketplace, Sequoia's primary competitors
include Hewlett-Packard, Sequent, Data General, Digital Equipment Corporation
("Digital"), IBM and Siemens.

  Sequoia's ruggedized systems and board level products compete in the
industrial market with the products of Diversified Technology, Industrial
Computer Source and I-Bus and, to a lesser extent, IBM and others in the United
States and with Siemens A.G. and others in Europe.  In the telecommunications
market, the Company competes with Digital, Motorola, Tandem, Stratus and
Hewlett-Packard, as well as several smaller companies.

  Sequoia believes that it competes effectively based on its engineering
responsiveness to special needs and the price/performance characteristics and
hardware specialization  of its products. These attributes help offset the
greater recognition and broader service and support resources of the Company's
larger competitors.

  The computer marketplace is highly competitive and is characterized by rapid
changes and improvements in technology. Many of Sequoia's competitors have
significantly greater financial, marketing and technological resources than
Sequoia. There can be no assurance that Sequoia will have the resources
necessary to compete successfully in the future.


  Product Development

  Development efforts are focused on providing users with an open systems
environment and a broad range of fault tolerance and ruggedized features up to
and including total system availability.  Sequoia's engineering strategy is to
continue to develop fault-tolerant and ruggedized capabilities that can be added
to industry-standard technologies. Through this product development strategy
Sequoia is able to provide industry-standard products that are compatible with
all standard software and hardware environments, but provide a 

                                      11
<PAGE>
 
much greater degree of system availability to users by focusing on reliability,
availability and data integrity as core features.

   Product development at Sequoia will build on the portfolio of fault tolerant
patents developed by the Company since 1985.  Sequoia will continue to advance
new passive backplane technology, introducing the latest versions of Pentium and
next generation (P-6) Intel CPUs.  Projects for the coming year include the
introduction of a new ruggedized hand held PC; the development of a symmetric
multiprocessing version of Intel's P-6 CPU in a passive backplane architecture;
and the prototyping of a new telecommunications platform based on a SPARC
multiprocessor that will employ Sequoia's "memory check pointing" failover
technology.


  Technology Licensing and Strategic Alliances

  An element of Sequoia's strategy is to enter into strategic alliances to help
achieve important goals:  the licensing of Sequoia's technology; the acquisition
of additional technology for sale with its systems; and the development of
additional product and distribution capabilities. Sequoia currently has
strategic alliances with Samsung Electronics Co., Ltd. ("Samsung"), Toshiba
Corporation ("Toshiba") and Novell, Inc. ("Novell"). Sequoia intends to seek
opportunities to form additional strategic alliances, including potential
acquisitions.

  Sequoia's ability to achieve its goals will depend in part on the ability of
current licensees, and the willingness of future licensees, to develop products
that may be marketed and sold by Sequoia, or which will provide license fees or
royalty income for Sequoia. There can be no assurance that Sequoia will be
successful in obtaining new licensees or that any such licensees will
successfully develop products that achieve market acceptance.

  Samsung
  -------

  In September 1993, Sequoia and Samsung entered into new agreements that
expanded upon and superseded original OEM and product development and
technology license agreements which had been signed in 1990. These agreements
have a term of five years and may be extended by mutual agreement.

  Sequoia has granted Samsung rights to use certain Sequoia technology in the
development of an enhanced Series 40 system and future products. Samsung has
agreed to pay Sequoia royalties with respect to its sales of Series 40 systems
(other than sales to Sequoia), and sales of future products which are based on
Sequoia's Motorola-based technology, subject to a credit of up to $4,800,000 for
Samsung's initial manufacturing license fee and development costs.  Sequoia, at
its option, may act as Samsung's maintenance provider for Series 400 and Series
40 products worldwide, except in Korea.

                                      12
<PAGE>
 
  Toshiba
  -------

  Sequoia and Toshiba entered into a development, manufacturing and distribution
agreement in December 1991, subsequently amended in April 1994, under which
Sequoia and Toshiba agreed to use Sequoia technology to jointly develop a new
computer system based on SPARC. Sequoia granted Toshiba exclusive distribution
rights in Japan for this SPARC-based system and retained exclusive rights to
distribute this SPARC-based system outside of Japan.

  In October 1994, Toshiba informed Sequoia that it had modified its development
plans and would develop a new fault-tolerant computer system based on the Power
PC microprocessor instead of the SPARC microprocessor as had been planned.
Sequoia has granted Toshiba a non-exclusive license to use existing Sequoia
technology in the development of such systems in consideration of a non-
refundable license fee which was completely paid during the fiscal 1994 and
1995.   New technology developed in the course of the development of the systems
will be jointly owned by Sequoia and Toshiba. Sequoia has the option to
manufacture such jointly-developed products or to purchase them from Toshiba on
an OEM basis for distribution outside of Japan. The agreement has an initial
term of five years from January 1992, with an automatic renewal period of one
year unless terminated by either party.

  Novell
  ------

  In April 1994, Sequoia signed a software development cooperation agreement
with Novell's UNIX System Laboratories ("USL"). Under this agreement, Sequoia
will work with USL and other USL partners to incorporate certain of Sequoia's
fault-tolerant features into future releases of Novell's microkernel-based UNIX
operating system. When completed, these future UNIX releases will be compatible,
without further modification, with Sequoia's procedures for recovering from
detected hardware and software faults.  Subsequently, Sequoia believes that it
would be able to offer the latest UNIX releases on its products as soon as such
releases become available from Novell  This could potentially open new
opportunities to offer selected modules of its fault-tolerant technology to
other distributors and users of USL's UNIX products, including the industry
leading companies in the client server market.

  Novell has recently announced that it is selling its Unix business to the
Santa Cruz Operation, Inc. ("SCO") in a business relationship that also includes
Hewlett-Packard Company.  If Novell, or assuming the consummation of this
transfer, SCO, does not include Sequoia's fault-tolerant software in a future
release of the UNIX operating system, or if the Novell implementation of UNIX
containing the Sequoia fault-tolerant software fails to achieve significant
market acceptance, Sequoia's growth opportunities will be diminished.

  Customer Service and Support

  Sequoia provides service, training and technical support to its customers in
varying degrees depending both on the product line and on customer contractual
arrangements.

  Sequoia's Motorola-based fault tolerant systems provide immediate fault
detection, isolation and correction. These functions are designed to take place
automatically, without requiring the user's intervention and while the system
continues operating. When a faulty component is detected, the system removes the
component from service, ensuring that no corrupted data will affect the rest of
the system. An electronic message is automatically sent to Sequoia's customer
support center by the malfunctioning system to report the error condition. The
system tests the isolated component and, if the system determines that the fault
is transient, the component is added back into the system. System use is not
disrupted during the course of this activity. For permanent faults, either a
component is dispatched via overnight delivery for customer replaceable units or
a field service engineer is dispatched to the customer's site to install the
part. In either case, the system assesses the remaining resources, balances the
work load among them automatically and continues operating.

  The architecture of the Motorola-based systems and the recently-announced
Intel-based systems allow Sequoia to utilize telemaintenance to perform many of
the tasks that must be performed by on-site field service engineers for other
systems. Telemaintenance, which consists of hot-line support, system monitoring,
remote diagnosis, operating system support and downloading, is provided by
Sequoia's customer support center.  This enables Sequoia to minimize labor costs
by reducing the number of on-site visits.

  For the Intel and SPARC based product lines, the technical support operations
provide initial technical telephone troubleshooting service for end user
customers and distributors. These services include isolating and verifying
product failures, authorizing product returns, tracking completion of repaired
goods in support of customer requirements and maintaining a Bulletin Board.

  Sequoia generally provides end-user purchasers of its systems with a 90-day to
two year warranty depending on the product line. Sequoia customer service
maintains a spares inventory to support the customer base.   Sequoia offers a
variety of service agreements to its end-user customers and resellers for
ongoing system support. Customers whose systems are under warranty or service
agreements are entitled to receive telemaintenance services. Sequoia also
provides technology migration, system optimization, network services, and
training programs to customers on a fee basis.

  Manufacturing

  Sequoia manufactures in two locations:
     . Motorola-based products in Marlborough, Massachusetts
     . Intel and SPARC-based products in Houston, Texas

  At its headquarters in Marlborough, Massachusetts, Sequoia's manufacturing
process for its Motorola-based products consists primarily of assembly, testing
and quality control.  The production of printed circuit boards is subcontracted
and the boards are then incorporated into Sequoia's systems.  Sequoia produces
standard subsystems which are tailored to customers' specific configurations
when purchase orders are received.  This method of manufacturing enables Sequoia
to respond quickly to customer needs while maintaining a high level of quality.

  The Sequoia Enterprise Servers, the Intel-based models 100 and 110, as well as
its ruggedized low-volume Intel board-level and system products, are
manufactured in Houston, Texas.  High-volume component manufacturing is
subcontracted to independent manufacturers.

  Sequoia purchases from other manufacturers substantially all peripheral
devices and components used in its products.  Most of the components and
peripherals are available from a number of different suppliers, although certain
major items are procured from single sources.  The Company believes that
alternative sources could be developed for such single-source items, if
necessary; however certain peripheral or component shortages, should they occur,
could have an adverse affect on the Company's business.  Key components used in
Sequoia systems for which alternative sources are not readily available are the
Motorola and Intel microprocessors, SPARC-based CPUs, and power supply
components for certain products from Elgin E2, Inc.  Any delay or inability to
obtain these components at any time could adversely affect Sequoia's business.
Certain products are manufactured pursuant to a patent license from IBM under
which the Company pays specified royalties.

  The Company relies on several key contract manufacturers for the manufacture
of several high-volume components used in the assembly of its ruggedized
products.  Although such subcontracting arrangements offer cost advantages, and
would eliminate the need to incur certain capital expenditures associated with
manufacturing, reliance on third-party manufacturers gives the Company less
control over the manufacturing process for these components than if it undertook
such activities itself.  Any failure of such subcontractors to manufacture and
deliver components as planned, or any problems with the quality of such
components, could have a material adverse effect on the Company's operations.

  Proprietary Rights

  Sequoia owns nine United States patents and 53 foreign patents.  Other United
States and foreign patent applications are pending. While Sequoia believes that
its patents provide it with protection for its products and the processes
through which its systems achieve fault tolerance, Sequoia also believes that
such patents may be of less significance to its future success than such factors
as innovation, technical skill and management ability and experience. In
addition, Sequoia relies on copyright protection and its trade secret program to
protect aspects of its proprietary technology.


  Employees

  As of June 30, 1995, Sequoia employed 443 people, including 141 in sales,
marketing and administration, 120 in research and development and related
engineering activities, 52 in customer service and support, and 130 in
manufacturing.  Sequoia believes that its future success will depend in part
upon its continued ability to attract and retain highly qualified managerial,
technical, sales, marketing, support and manufacturing personnel.  Competition
in recruiting technical, marketing and sales personnel in the computer industry
is often intense.  None of Sequoia's employees is represented by a labor union,
and Sequoia considers its employee relations to be good.


  Backlog

  At June 30, 1995, the Company had an unfilled order backlog of approximately
$8.7 million, which was subject to shipment in the subsequent fiscal quarter, as
compared to $5.3 million at June 30, 1994.  This backlog consists primarily of
orders which were taken in the fourth quarter and are shipped according to
specific customer-scheduled requests.

  Seasonality

  Although the Company does not consider its business to be highly seasonal, the
Company in general experiences seasonally lower sales and earnings in the first
quarter of the fiscal year which is affected by the U.S. and Europe summer
slowdowns for business capital purchases.

  ITEM 2.   DESCRIPTION OF PROPERTIES

  The Company occupies two primary facilities in the U.S. for administrative,
manufacturing, marketing and sales, warehousing and research and development
functions consisting of approximately 85,000 square feet in Marlborough,
Massachusetts and 105,000 square feet in Houston, Texas.  The Company occupies
these premises under leases expiring in 1997 and 2000, respectively. The Company
leases ten additional offices, primarily for sales and services, in various
locations throughout the United States. The Company also leases space for sales
and service offices in the United Kingdom, the Netherlands, Germany, Australia
and Japan.  The Company's aggregate annual rental expense for these facilities
for the fiscal year ended June 30, 1995 was approximately $2,098,000. The
Company believes that its current facilities are adequate for its near term
requirements.  See Note 6 of Notes to Consolidated Financial Statements for
additional information regarding the Company's lease obligations.

  ITEM 3.   LEGAL PROCEEDINGS

     On May 8, 1992, the Securities and Exchange Commission notified the Company
that the Commission had begun an informal investigation with respect to the
Company's revenue recognition policies. On September 28, 1992, after receiving
certain documentation and information requested from the Company, the Commission
notified the Company that the Commission had entered a formal order of
investigation with respect to these matters. On February 16, 1995, the Company
and the Commission entered into a settlement agreement, subsequently approved by
the U.S. District Court for the District of Columbia, pursuant to which the
Company consented to the issuance of an injunction against it prohibiting future
violations of certain securities laws and regulations, and the Company was not
required to pay any fines or make any other payments.


  ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted to a vote of security holders of the Company,
through solicitation of proxies or otherwise, during the fourth quarter of the
fiscal year ended June 30, 1995.

  ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
          FINANCIAL CONDITION AND RESULTS OF OPERATIONS


  On March 31, 1995, the Company completed a merger and stock purchase (the
"Transaction") pursuant to which the Company acquired all of the common stock of
SPCO, Inc., along with its subsidiaries Texas Microsystems, Inc. and Texas Micro
Electronics, Inc. (collectively, the "TMI Group"). The Company issued 5,272,944
shares of its common stock in exchange for all the common stock and securities
to acquire the common stock of each of the members of the TMI Group. The
Transaction has been accounted for as a pooling of interests, and accordingly,
the consolidated financial statements for all comparative periods have been
restated to include the results of operations, the financial position and cash
flows of the TMI Group.

  The Company provides Motorola-based systems and upgrade products for on-line
transaction processing and other interactive applications in which system
availability, fast response times and data integrity are critical.  With the
acquisition of the TMI Group, the Company's expanded business lines also include
ruggedized, mission-critical computers, both SPARC and Intel based, for the
industrial market and Bellcore Network Equipment Building Specifications
("NEBS") compliant products specifically designed for the telecommunications
market. As a leading supplier of ruggedized and mission critical computers from
the desktop to the mainframe, the Company operates in one segment, computer
systems, and addresses expanding market requirements for greater system
availability.


  RESULTS OF OPERATIONS
  YEARS ENDED JUNE 30, 1995 AND 1994

  REVENUES
  --------

  The Company's revenues increased by 13% to $104,039,000 for fiscal 1995 from
$91,826,000 for fiscal 1994. This is attributable to a 15% increase in product
revenues and a 9% increase in service revenues.

  Product revenue growth of $11,620,000 was attributable to (i) sales, which
more than doubled, of NEBS compliant SPARC and Intel based products specifically
designed for the telecommunications market and (ii) a 5% increase in ruggedized
Intel based products for the industrial market. These gains were partially
offset by a 5% decrease in sales of Motorola-based products for the on-line
transaction processing market.

  The increased sales of NEBS compliant SPARC and Intel based products for the
telecommunications market were caused primarily by significantly higher demand
from one customer in the second half of fiscal 1995, from which such demand is
not expected to 

                                      22
<PAGE>
 
continue at this level for fiscal 1996. The increased revenues were comprised of
a 30% increase in units shipped and a significant increase in the average system
price which reflects higher functionality and performance. The Company expects
that sales of these products overall will increase although at a slower rate of
growth than in fiscal 1995.

  On February 1, 1995, the Company acquired certain assets of Intel Corporation
("Intel") related to Intel's OmniRACK and XpressRACK product lines. These
products, sold to Intel as well as other customers, contributed $2,523,000, the
significant proportion of the 5% increase in fiscal 1995 ruggedized product
revenues over fiscal 1994 revenues. This growth in ruggedized sales was
comprised of an 11% increase in units shipped offset by a slight decline in
average system price which reflects a more mature product life cycle.  Planned
product transitions during fiscal 1996 to the next performance level of CPU may
result in higher average system prices.  However, these are expected to be
offset by higher discounts expected as the Company plans, in fiscal 1996, to
derive a higher proportion of its revenues through an independent distribution
channel.

  During fiscal 1995 and fiscal 1994, approximately 70% and 65%, respectively,
of revenues from sales of ruggedized products and products designed for the
telecommunications markets were derived from the sale of computer systems and
peripherals and approximately 30% and 35%, respectively, were derived from the
sale of board-level products.

  The decline in Motorola-based products was attributable to a substantially
lower level of new systems shipped compared to fiscal 1994, as new system sales
were slower pending new product introductions and as overall market demand for
Motorola-based systems declined in the United States.  This decline in new
systems was partially offset by an increased level of upgrade and expansion
sales to the Company's installed base.

  On July 1, 1994 the Company purchased selected assets and the ongoing business
operations of its Australia joint venture with Tricom Group Pty Ltd. In fiscal
1995, this newly formed subsidiary contributed $5,798,000 in Motorola-based
products and related services revenues, as compared to $1,332,000 when operated
as a distributor in fiscal 1994.  Approximately 9% or $1,246,000 represents
increases in service revenues,  primarily a result of the service revenue stream
generated from this acquisition.

  Sales outside the United States comprised $23,445,000, or 22% of total
revenues for fiscal 1995, as compared to $19,305,000 or 21% of fiscal 1994
revenues. These increases were primarily attributable to the additional revenues
provided from the Company's Australian subsidiary.

  In the fourth quarter, fiscal 1995, the Company received $1,000,000 for
software license fees, as reported in Other Revenues, as the final payment from
Toshiba Corporation ("Toshiba") as part of a development and distribution
agreement.  In fiscal 1994, the Company received $1,500,000 for software license
fees from Toshiba.

                                      23
<PAGE>
 
  During fiscal 1995, sales to one customer, DSC Communications Corporation,
represented 13% of total revenues.  For fiscal 1994, there were no sales to any
customer that represented over 10% of total revenues.

  The Company believes that certain Value Added Resellers ("VAR's") in the
healthcare market and customers in the telecommunications market will continue
to represent a substantial portion of overall sales.  Changes in the Company's
relationship with, performance by or loss of such customers could have a
significant effect on the Company's revenues and operating results.

  During fiscal 1995, Motorola-based product revenues consisted primarily of
sales of expansion systems, or upgrades, to existing customers who have
increased information processing requirements, rather than systems sales to new
customers.  While sales of such expansion systems have provided a reliable
source of revenues during periods when sales to new customers have been
particularly slow, revenues from the sales of expansion systems and upgrades
will likely decline during fiscal 1996 since the Company intends to develop
limited upgrade or expansion features for these products that would be
attractive to existing customers. The Company began shipping in the fourth
quarter lower priced Motorola-based fault-tolerant systems designed to be sold
to new customers. The Company has announced, subsequent to the 1995 fiscal year,
the introduction of a new line of enterprise servers using Intel processors to
expand sales which is expected to offset the decline of Motorola-based products.

  The markets for NEBS compliant SPARC and Intel based products and ruggedized
Intel based products are characterized by rapidly changing technology and user
needs, requiring significant investment for product development.   The Company
believes that a large part of its ability to increase revenues in the future
will depend upon its ability to develop, manufacture and market new products
which meet changing user needs in these markets and which successfully respond
to technological changes in architectural standards in a cost-effective and
timely manner.

  The Company's future success will also depend in part on the market acceptance
of its recently announced new line of Intel servers for the on-line transaction
processing market and the ability of current and the willingness of future
licensees of the Company's proprietary technology to develop products and
technology that may be marketed and sold by the Company, or which provide
royalty income for the Company.

  GROSS MARGIN
  ------------

  Gross margin declined by 3% to 45% for fiscal 1995 from 48% for fiscal 1994.
The decrease in gross margin was due to decreases both in product margins to 44%
for fiscal 1995 as compared to 46% for fiscal 1994, and decreases in customer
service and other margins to 49% for fiscal 1995 as compared to 56% for fiscal
1994.

                                      24
<PAGE>
 
  Gross profits increased $3,143,000 to $46,960,000 for fiscal 1995 as compared
to $43,817,000 for fiscal 1994.  This increase resulted from the higher revenues
which were partially offset by the decline in margins.

  The decrease in product margin is primarily related to a 2% decline in the
margins for Motorola-based products due to the introduction of new systems sold
at the low end of the market.  Ruggedized product margins held relatively
constant for fiscal 1995 as compared to fiscal 1994. Sales of refurbished
equipment, acquired through upgrade programs, contributed 2% to 1995 product
gross margins.  Sales of refurbished equipment are expected to continue in
fiscal 1996. In addition, in fiscal 1994, sales of approximately $900,000 of
inventory previously written off had contributed 1% to fiscal 1994 product gross
margin.

  The decrease in service and other margin is caused by (i) lower service
pricing for higher reliability Motorola VME-based products; (ii) additional
costs due to increases in staffing within the product support group and the
professional services group, and (iii) lower technology license fees in fiscal
1995 as compared to fiscal 1994.

  The Company expects continued pressure on gross margins as the product revenue
mix shifts to a higher proportion of Intel and SPARC based ruggedized products
which carry lower margins than the Motorola-based systems, upgrades and
expansion products.   Fluctuations in margin levels may result from the mix of
product revenues and respective varying margin contributions from sales of
ruggedized products to the telecommunication and industrial markets and
Motorola-based products.


  RESEARCH AND DEVELOPMENT EXPENSES
  ---------------------------------

  The Company's research and development expenses increased 12% to $13,044,000
for fiscal 1995 from $11,621,000 in fiscal 1994.  These increases resulted
primarily from efforts made to support the continuing joint development program
with Novell,  to develop operating software programs for new open system
products,  to further expand  product offerings for the telecommunications
market and to continue to introduce hand held and mobile computer ruggedized
products.

  Research and development expenses as a percentage of revenues remained
relatively unchanged in fiscal 1995 as compared to fiscal 1994 at 13%, as
spending on research and development programs increased in proportion to the
revenue increases year over year.


  SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES
  ---------------------------------------------

  Selling, general and administrative expenses increased 27% to $28,052,000 for
fiscal 1995 as compared to $22,053,000 for fiscal 1994.  This increase   was
primarily the result of four factors: (i) expenses related to the acquisition
of the TMI Group; (ii) increased 

                                      25
<PAGE>
 
selling expenses related to the higher revenue volume; (iii) new advertising and
increased marketing programs; and (iv) additions in personnel.

  More specifically (i) the Company incurred expenses of $2,146,000 in
connection with the acquisition of the TMI Group, primarily for fees to
financial advisors and for legal, accounting and printing services;  (ii)
commissions and external VAR fees increased as a result of the increase in sales
volume; (iii) new corporate advertising was initiated and marketing promotion
programs increased related to new products and the expansion of sales channels;
and (iv) personnel additions were focused on expanding distribution channels in
the U.S. telecommunications market and staffing the Australian subsidiary which
commenced operation on July 1, 1994.


  OPERATING INCOME
  ----------------

  The Company reported operating profits of $5,864,000 during fiscal 1995, as
compared to $11,252,000 during fiscal 1994.  The decrease in operating profit
was primarily the result of reduced gross margins, the expenses related to the
completion of the acquisition of the TMI Group and other increases in operating
expenses.  In addition, fiscal 1994 operating profits reflect a restructuring
credit of $1,109,000 and the sales of previously written off inventory of
$900,000.


  INTEREST INCOME / (EXPENSE)
  ---------------------------

  The Company had interest income of $809,000 for fiscal 1995, as compared to
interest income of $345,000 for fiscal 1994.  The increase in interest income
resulted from higher average cash and short-term investment balances earning
higher interest rates as well as lower capital lease obligations during fiscal
1995.

  The Company had interest expense of $290,000 for fiscal 1995, as compared to
interest expense of $561,000 for fiscal 1994.  The decrease reflects the June 7,
1994 paydown  of a subordinated note, which carried a substantially higher
interest rate, to Keystone International, Inc. ("Keystone") using proceeds of a
three year term bank note and a revolving credit facility.


  OTHER INCOME / (EXPENSE)
  ------------------------

  Foreign currency translation and transaction gains and losses accounted for
substantially all of the other income (expense).  Fluctuation in these amounts
from fiscal 1994 to fiscal 1995 are  a result of currency fluctuations in the
countries in which the Company conducted its business.

                                      26
<PAGE>
 
  INCOME TAXES
  ------------

  The Company recorded provisions for income taxes of $960,000 for fiscal 1995
and $658,000 for fiscal 1994.   These tax provisions reflect the combination of
the Company's  pre-merger provisions for income taxes for federal alternative
minimum tax and state tax liabilities, and the pre-merger tax provisions of the
TMI Group.


  RESULTS OF OPERATIONS
  YEARS ENDED JUNE 30, 1994 AND 1993

  REVENUES
  --------

  The Company's revenues increased 13% to $91,826,000 for fiscal 1994 as
compared to $81,323,000 for fiscal 1993. The increase was primarily due to a 10%
increase in product revenues largely from increased volume of ruggedized product
sales, an 18% increase in customer service revenues from $11,571,000 to
$13,636,000 and the receipt of a $1,500,000 software license fee from Toshiba in
fiscal 1994.

  For the Motorola-based products, product revenues during fiscal 1994 consisted
primarily of sales of expansion systems and upgrades to existing customers
having increased information processing requirements rather than system sales to
new customers. Motorola product revenues increased slightly in fiscal 1994 as
compared to fiscal 1993, which reflected an increase in sales of expansion
systems and upgrades offset by a reduction in sales of new systems sold. During
the third quarter of fiscal 1994, the Company's VME technology was introduced.
VME based products accounted for 40% of fourth quarter total Motorola system and
system upgrade revenues and 23% of total Motorola system and system upgrade
revenues for the full fiscal year.

  Revenues for the ruggedized Intel and SPARC based products increased 16% for
fiscal 1994 as compared to fiscal 1993.  The increase in revenues was primarily
attributable to increased international sales resulting from the European
economic recovery and increased penetration of the United States
telecommunications market.  During fiscal 1994 and fiscal 1993, approximately
65% and 72%, respectively, of revenues from sales of ruggedized products and
products designed for the telecommunications markets were derived from the sale
of computer systems and peripherals and approximately 35% and 28%, respectively,
were derived from the sale of board-level products.


  The Company's sales outside the United States during fiscal 1994 and fiscal
1993 were $19,305,000 and $12,996,000 respectively, representing 21% and 16% of
revenues during such years. This increase reflects the receipt of a $1,500,000
software license fee from Toshiba  in Japan during fiscal 1994 compared to
minimal licenses fees from this region in fiscal 1993 and increased sales of
ruggedized products in Western Europe and Asia during fiscal 1994.

                                      27

     There were no sales to any one customer in fiscal 1994 or fiscal 1993 that
represented over 10% of total revenues.


  GROSS MARGIN
  ------------

  The Company's gross margin increased to 48% for fiscal 1994 as compared to 42%
for fiscal 1993 as a result of (i) an increase of 4% in fiscal 1994 product
margins as compared to fiscal 1993, (ii) an increase of 10% in fiscal 1994
service margins as compared to fiscal 1993, and (iii) the receipt of a
$1,500,000 software license fee from Toshiba  in fiscal 1994.

  Contributing to the favorable product margins, particularly in the Motorola-
based products, were significant overhead cost reductions in manufacturing,
including facility consolidations and the sale of approximately $900,000 of
previously written off inventory.  Partially offsetting these were slight
decreases in the ruggedized product line margins caused by a more competitive
pricing policy with respect to chassis products sold with Intel-based CPUs,
higher discounts to some high-volume customers and, to a lesser extent, a
general decline in margins in the microcomputer industry.

  The increase in services margin was primarily the result of an increase in
service revenues with services costs holding constant and partially associated
with the retroactive billing of $230,000 of maintenance charges for services
performed at a cost of approximately $105,000 prior to contract execution.


  RESEARCH AND DEVELOPMENT EXPENSES
  ---------------------------------

  The Company incurred research and development expenses of $11,621,000 and
$15,104,000 in fiscal 1994 and fiscal 1993, respectively.  The $3,483,000
reduction in expenses was the result of substantial reductions in personnel
related expenses and a reduction in depreciation expense resulting from the
write-off of idle assets associated with the Company's restructuring during the
second fiscal quarter ended December 27, 1992.  Research and development
expenses as a percentage of revenues decreased to 13% in fiscal 1994 as compared
to 19% in fiscal 1993.


  SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
  --------------------------------------------

  Selling, general and administrative expenses decreased 29% to $22,053,000 in
fiscal 1994 as compared to $31,187,000 in fiscal 1993.  The decrease was the
combined result of personnel reductions, vacated leased facilities and reduced
depreciation charges related to written off equipment resulting from the
Company's restructuring during the second fiscal quarter ended December 27,
1992, as well as decreases in certain expenses such as external 

                                      28
<PAGE>
 
commissions, bad debt provisions, and audit and legal fees associated with
shareholder lawsuits.

  As a percentage of revenues, selling, general and administrative expenses
decreased to 24% in fiscal 1994 from 38% in fiscal 1993.


  RESTRUCTURING CHARGE / (CREDIT)
  -------------------------------

  During fiscal 1993, the Company recorded a $13,990,000 restructuring charge to
reduce the carrying value of excess assets and to accrue costs for anticipated
liabilities arising from a restructuring and downsizing of the business in
December 1992.  As a result of the restructuring, the Company reduced its
personnel, leased facilities and equipment utilized in the business.  The impact
of these reductions in fiscal  1994 was to lower the associated operating
expenses by approximately $14,500,000.  During fiscal 1994, the Company
recognized a $900,000 gain from the sale of previously written-off inventory,
which was not expected to be sold at the time of the restructuring.

  By the end of fiscal 1994, substantially all of the restructuring activities
were completed and the utilization of the restructuring reserves had been
consistent with the original estimates and reflected actions planned and
implemented.  Excess reserves totaling $1,109,000 were reversed in fiscal 1994
as a result of the Company's ability, through successful negotiations with
lessors and vendors, to settle certain of its commitments for amounts lower than
its contractual obligations.  These excess reserves consisted principally of
amounts accrued for commitments for leases, software licenses and engineering
services. As of  June 30, 1994, the remaining accrued restructuring balance
amounted to $373,000 for contractual obligations.


  OPERATING INCOME
  ----------------

  The Company incurred an operating profit of $11,252,000 in fiscal 1994 versus
an operating loss of $25,825,000 in fiscal 1993.  Excluding the fiscal 1993
restructuring charges and class action settlement, the fiscal 1994 operating
profit resulted from higher revenues and gross profit, lower operating expenses,
the license fee from Toshiba of $1,500,000 and the reversal of a restructuring
reserve of $1,109,000.


  INTEREST INCOME / (EXPENSE)
  ---------------------------

  The Company had interest income of $345,000 in fiscal 1994 compared to
interest income of $222,000 in fiscal 1993.  This improvement was the combined
result of higher cash balances, the paydown of bank debt and reduction of
capital lease obligations in fiscal 1994.

                                      29
<PAGE>
 
  The Company had interest expense of $561,000 in fiscal 1994 compared to
$1,016,000 in fiscal  1993. This decrease was the result of the reduction of
outstanding debt and lower average interest rates.

  OTHER INCOME / (EXPENSE)

  Foreign currency translation and transaction gains and losses, accounted for
substantially all of the other income (expense). Fluctuation in these amounts
from fiscal 1993 to fiscal 1994 are a result of currency fluctuations in the
countries in which the Company conducted its business.


  INCOME TAXES
  ------------

  The Company recorded a provision for income taxes in the amount of $658,000 in
fiscal 1994 as compared to $512,000 in fiscal 1993.  This amount reflects
alternative minimum tax requirements and foreign withholding taxes. See Note 4
of the Notes to Consolidated Financial Statements.

  In addition, during fiscal 1993, the IRS disallowed certain of the TMI Group's
pre-acquisition deductions related to the acquisition of certain assets from
Keystone in May 1989. To cover this assessment, the fiscal 1993 income tax
provision included an additional $346,000. In fiscal 1994, the TMI Group reached
an agreement with the IRS, as a result of which the original assessment was
reduced by $215,000. Since the original assessment was expensed by the TMI Group
in fiscal 1993, the Company recorded a tax benefit of $215,000 in fiscal  1994
with respect to this matter.

  Effective July 1, 1992, the TMI Group adopted SFAS No.109, "Accounting for
Income Taxes," which replaces SFAS No. 96. The adoption of SFAS No. 109 resulted
in a benefit of $171,000 which was recorded as a cumulative effect of change in
accounting for income taxes in fiscal 1993.


  LIQUIDITY AND CAPITAL RESOURCES


  At June 30, 1995, the Company had cash and cash equivalents and working
capital of $15,317,000 and $29,885,000, respectively, compared to cash and cash
equivalents and working capital of $21,024,000 and $26,270,000, respectively, at
June 30, 1994. The reduction in cash and cash equivalents was largely due to the
acquisition of the net assets of the Company's Australian distributor on July 1,
1994 for $1,100,000 and the paydown of all bank and long term debt of Texas
Microsystems, Inc. during the fourth quarter totaling $5,229,000.

                                      30
<PAGE>
 
  In fiscal 1995 as in fiscal 1994, the Company funded its operations through
positive cash flow from operations.  Cash flows from operations reflected net
income offset by cash outflows for inventories.

  The Company generally ships systems within 30 days after receipt of specific
purchase orders from customers.  In order to do so, the Company typically
produces and maintains an inventory of subsystems in standard configurations.
Inventories including customer spares increased to $16,713,000 at June 30, 1995
from $9,698,000 at June 30, 1994, due to the purchase of inventory as part of
the acquisition of the Australian distributor and the procurement of inventories
associated with the introduction of new products, planned higher revenue levels
and backlog.  The Company expects that its inventory levels will grow in fiscal
1996, but at a slower pace in relationship to revenue growth, reflecting
management's objective to increase inventory turns.

  At June 30, 1995, the Company's net accounts receivable totaled $12,739,000
compared to $12,759,000 at June 30, 1994.  The Company's days sales outstanding
at June 30, 1995 was 44 days, a decrease from 50 days at June 30, 1994.

  Capital expenditures totaled $2,478,000 for fiscal 1995, and were comprised
primarily of computer equipment, including the capitalization of internally
manufactured systems, and software licenses.  This compared with fiscal 1994
capital expenditures of $2,254,000, also primarily comprised of computer
equipment.  The Company expects to slightly increase capital expenditures in
fiscal 1996 related to increased investment and development in the Intel and
SPARC-based product lines.

  During 1995, the Company through its subsidiary Texas Microsystems, Inc., had
a $2,000,000 term loan and a maximum $4,000,000 revolving line of credit with
Texas Commerce Bank, National Association and a note payable to Keystone
International, Inc. In the fourth quarter fiscal 1995, subsequent to the
Transaction, the Company paid down fully all bank and long term debt of Texas
Microsystems, Inc. totaling $5,229,000.

  The Company terminated its previous $10,000,000 credit line with State Street
Bank and Trust Company and in connection with the completion of the Transaction,
on March 31, 1995, the Company, State Street Bank and Trust Company and Texas
Commerce Bank, National Association, entered into a new credit agreement that
provides for maximum borrowings of $20,000,000 secured by substantially all the
assets of the Company.  At the Company's option, loans may be drawn down subject
to two interest rate alternatives:  (i) a prime rate option bearing interest at
the then current prime rate and (ii) a LIBOR option bearing interest at the
LIBOR rate plus 2%.   The Company is required to meet specific covenants
throughout the duration of this agreement. Available borrowings under this
agreement are subject to a borrowing base formula.  The agreement expires on
October 31, 1996. At June 30, 1995, no amounts were outstanding under this
agreement and the Company had $7,549,000 available under the borrowing base
formula.

                                      31

The Company believes that its present cash and cash equivalents, working capital
levels, and borrowing capacity are adequate for its operating needs through
fiscal 1996.

                       REPORT OF INDEPENDENT ACCOUNTANTS




To the Board of Directors and Stockholders of Sequoia Systems, Inc.:


We have audited the accompanying consolidated balance sheets of Sequoia Systems,
Inc. and subsidiaries as of June 30, 1994 and 1995 and the related consolidated 
statements of operations, cash flows and stockholders' equity for each of the 
three years in the period ending June 30, 1995. These financial statements give 
retroactive effect to the merger of Sequoia Systems, Inc. and the TMI Group on 
March 31, 1995, which has been accounted for using the pooling of interests 
method as described in Note 1 to the consolidated financial statements. 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 did not audit the financial statements of the TMI Group for any 
year prior to June 30, 1995 which statements reflect total assets constituting 
35% of consolidated total assets as of June 30, 1994, and which reflect total 
revenues constituting 51% and 19% of consolidated total revenues for each of the
years ending June 30, 1994 and 1993, respectively. Those statements were 
audited by other auditors whose report has been furnished to us, and our 
opinion, insofar as it relates to the amounts included for the TMI Group, is 
based solely on the report of the other auditors.

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

In our opinion, based on our audits and the report of other auditors, the 
consolidated financial statements referred to above present fairly, in all 
material respects, the consolidated financial position of Sequoia Systems, Inc. 
and subsidiaries at June 30, 1994 and 1995, and the consolidated results of 
their operations and their cash flows for each of the three years in the period 
ending June 30, 1995, in conformity with generally accepted accounting 
principles.

                                                     COOPERS & LYBRAND L.L.P.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Boards of Directors of the
  Texas Microsystems Group:

     We have audited the combined balance sheets of the Texas Microsystems
Group, as of June 30, 1994 and 1993, and the related combined statements of
operations, shareholders' equity and cash flows for the years then ended (not
presented separately herein). These combined financial statements are the
responsibility of the Group's management. Our responsibility is to express an
opinion on these combined financial statements based on our audits.

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

     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of the Texas 
Microsystems Group as of June 30, 1994 and 1993, and the results of their
operations and their cash flows for the years then ended in conformity with 
generally accepted accounting principles.

     Effective July 1, 1992, the Group adopted Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes."

 Note 1  Basis of Presentation
 ------                       

     The Company provides Motorola-based systems and upgrade products for on-
line  transaction processing and other interactive applications in which system
availability, fast response times and data integrity are critical.  With the
acquisition of the TMI Group, the Company's expanded business lines also include
ruggedized, mission-critical computers, both SPARC and Intel based, for the
industrial market and Bellcore Network Equipment Building Specifications
("NEBS") compliant products specifically designed for the telecommunications
market. As a leading supplier of ruggedized and mission critical computers from
the desktop to the mainframe, the Company operates in one segment, computer
systems, and addresses expanding market requirements for greater system
availability.



     A.   Merger and Stock Purchase

     On November 9, 1994, the Company and its acquisition subsidiary entered
into a definitive merger and stock purchase agreement with SPCO, Inc. and
Keystone International, Inc., by which the Company acquired all of the common
stock of SPCO, Inc., along with its subsidiaries Texas Microsystems, Inc. and
Texas Micro Electronics, Inc. and their respective subsidiaries (the "TMI
Group") (collectively the "Transaction").  On March 31, 1995, the Transaction
was consummated and the Company issued 5,272,944 shares of its common stock in
exchange for all the common stock and securities to acquire the common stock of
each of the members of the TMI Group.

     The Transaction has been accounted for as a pooling of interests, and
accordingly, the historical consolidated financial statements for all periods
prior to the acquisition have been restated to include the results of
operations, the financial position and cash flows of the TMI Group.  The terms
of the Transaction are fully described in the Company's Registration Statement
on Form S-4 (file No. 33-54777) under the Securities Act of 1933, filed with the
Securities and Exchange Commission on February 21, 1995 and amended on February
24, 1995.

     Total transaction costs of approximately $2,134,000 were expensed as
incurred in the first nine months of fiscal 1995.  These transaction costs
included fees to financial advisors and legal, accounting, printing and other
related expenses incurred in connection with the merger.

     B.   Restructuring Charge/Credit

The Company recorded a restructuring charge of $13,990,000 in fiscal 1992 as the
result of lower revenues and a downsizing of the operations based on anticipated
future revenue levels. The restructuring charge included: $4,022,000 for
provisions to reduce the carrying value of excess inventory, $3,077,000 for
provisions to write off idle equipment and improvements, and $3,242,000 for
provisions to reduce the carrying value of other current and long-term assets to
their estimated net realizable values. The restructuring charge also included
$2,494,000 of provisions for lease obligations for abandoned facilities, and
$1,155,000 for other contractual obligations and provisions.  During fiscal
1994, the Company settled the lease, contractual, and other obligations, and
determined that, as of June 30, 1994, $1,109,000 of restructuring charges was in
excess of the business requirements and recorded a restructuring credit.
Additionally, the Company realized a benefit in cost of revenues of $900,000 in
fiscal 1994 as a result of the sale of inventory which had been written-off as
part of the restructuring.  As of June 30, 1995, restructuring activities were
completed.

Note 2    Summary of Significant Accounting Policies
- ------                                              

The consolidated financial statements reflect the application of certain
accounting policies described in this and other notes to consolidated financial
statements.

     A.   Principles of Consolidation

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

     B.   Cash and Cash Equivalents

Cash and cash equivalents are stated at cost, which approximates market. Cash
equivalents consist of highly liquid investments with original maturities of 90
days or less.

     C.   Inventories

Inventories are stated at the lower of average cost (first-in, first-out) or
market which requires the periodic assessment of net realizable value. The
difference of cost and market is charged to income in the period the impairment
is determined. Inventory including materials, labor and manufacturing overhead
consists of the following:

                   -------------------------
</TABLE>

     D.   Depreciation and Amortization

The Company provides for depreciation and amortization by charges to operations
in amounts estimated to allocate the cost of equipment and leasehold
improvements over their estimated useful lives on a straight-line basis.
Computer equipment, machinery and equipment, equipment under capital lease and
furniture and fixtures are depreciated over three to ten years, and leasehold
improvements are amortized over the term of the associated leases.

The cost of improvements is charged to the property accounts, while maintenance
and repairs are charged to income as incurred. The Company periodically
evaluates its fixed assets to determine whether assets are impaired or continue
to be utilized.   Upon determination of an impairment, retirement or other
disposition of property and equipment, the cost and related depreciation are
removed from the accounts, and any resulting gain or loss is reflected in the
results of operations.

     E.   Software License Fees and Royalties

The Company has entered into license and royalty agreements for software to be
incorporated into certain computer systems held for resale. The initial fees
under such software license arrangements are capitalized in other assets and
amortized over the lesser of the term of the license agreement or on a straight-
line basis over three to five years. Royalty payments are expensed upon the sale
of computer systems that incorporate the licensed software.

     F.   Revenue Recognition

Revenues from product sales, which include revenues from software licenses are
recognized upon shipment unless significant uncertainties exist.  Service
revenues include maintenance, installation fees and professional services; other
revenues include rental revenue and technology license fees. Service revenues
related to maintenance agreements are recognized ratably over the period in
which the service is provided. All other service revenues are recognized as
earned.  Other revenue, primarily technology license fees, are recognized as
revenue upon receipt of non-refundable payments.

The Company entered into a development, manufacturing and distribution agreement
with Toshiba Corporation in December 1991 and amended such agreement in April
1994. Technology license fees due the Company, amounted to $1,000,000 and
$1,500,000, for the years ended June 30, 1995 and 1994, respectively.

     G.   Research and Development

Costs relating to research and development are expensed as incurred.

     H.   Net Income (Loss) per Share

Primary and fully diluted earnings per share are not separately stated as they
are substantially the same.  For the years ended June 30, 1995, 1994 and 1993,
net income/(loss) per share was based on the weighted average number of common
and common share equivalents outstanding during the year, computed in accordance
with the treasury stock method.  Under this method, common share equivalents are
not included in the calculation for fiscal 1993 as their impact would be
antidilutive.  The net income/(loss) per share calculations for all years
presented include shares issued to consummate the pooling transaction on March
31, 1995 (see Note 1 A).

     I.   Foreign Currency Translation

For foreign subsidiaries where the functional currency is the U.S. dollar, the
financial statements of the Company's foreign subsidiaries are translated using
rates of exchange in effect at the end of the fiscal year for monetary assets
and liabilities and historical rates for non-monetary assets and liabilities.
Income and expenses are translated at average exchange rates prevailing during
the fiscal year and the resulting gains or losses are reflected in results of
operations..  For foreign subsidiaries where the functional currency is the
local currency, the financial statements are translated as above except that
assets and liabilities are translated at current exchange rates and the
resulting gains or losses are recorded as a separate component of stockholders'
equity.

Transaction gains and (losses) recognized by the Company amounted to $(82,000),
$(9,000), and $1,000 for the years ended June 30, 1995, 1994, and 1993,
respectively.

     J.   Postretirement Benefits

The Company sponsors two defined contribution employee savings and retirement
plans (the Plans), which cover only U.S. employees.  Employees participate in
the Plans based on the subsidiary of their employment.  The Plans are
contributory for which contributions by the Company are made at the discretion
of management.  Employees may contribute up to 15% or 20% of their annual
compensation depending on their respective plan. The Company made contributions
of $231,000, $236,000 and $125,000 in fiscal 1995, 1994 and 1993 respectively.

     K.   Concentrations of Credit Risk

The Company's financial instruments that are exposed to concentrations of credit
risk consist primarily of cash equivalents and trade  receivables.  The
Company's cash equivalents are placed with high credit quality financial
institutions or invested in government securities.  The Company limits the
amount of credit exposure to any one institution.

Concentrations of credit risk with respect to trade receivables are limited due
to the varied customer base, comprised principally of distributors and
resellers, dispersed across various industries and geographic locations.  The
Company generally does not require collateral; however, in certain circumstances
the Company may require letters of credit from its customers.  The Company may
require deposits to be paid with an order or may negotiate added discounts in
exchange for payment at time of shipment.

     L.   Reclassifications

Certain prior year balances have been reclassified to conform to current year
presentation.

     M.   Income Taxes

The Company accounts for income taxes in accordance with Statement of Financial
Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes".  Under the
liability method specified by SFAS No. 109, deferred tax assets, net of any
valuation allowance, and deferred tax liabilities are determined based on the
temporary differences between the financial statement and tax basis of assets
and liabilities and net operating losses as measured using the enacted tax rates
which are expected to be in effect when these differences reverse.

     N.    Warranty Obligations

The Company generally provides its systems with a 90-day to two year warranty
from the date of installation depending on the product line.  Estimated warranty
obligations are evaluated and provided at the time of sale.

Note 3    Note Payable to Bank & Long-Term Debt
- ------                                         

The Company, through its subsidiary Texas Microsystems, Inc. had (i) a
$2,000,000 term loan, payable in equal monthly installments based on a three-
year amortization with the balance due on June 1, 1997, (ii) $4,000,000
revolving line of bank credit and (iii) a zero coupon note payable to Keystone

down all bank and long term debt of Texas Microsystems, Inc. totaling $5,229,000
and terminated these agreements.

On March 22, 1994, the Company and State Street Bank and Trust Company entered
into a credit agreement which provides for maximum borrowings of $10,000,000.
Borrowings under this agreement bear interest at the rate of prime to prime plus
1%, dependent on certain ratios.  At June 30, 1994, no amounts were outstanding
under this agreement and the Company had $3,060,000 available under the
borrowing base formula.

The Company terminated its previous credit line with State Street Bank and Trust
Company and in connection with the completion of the Transaction, on March 31,
1995, the Company, State Street Bank and Trust Company and Texas Commerce Bank,
National Association entered into a revolving credit agreement providing for
maximum borrowings of $20,000,000 secured by substantially all the assets of the
Company.  At the Company's option, loans may be drawn down subject to two
interest rate alternatives:  (i) a prime rate option bearing interest at the
then current prime rate and (ii) a LIBOR option bearing interest at the LIBOR
rate plus 2%.

The Company is required to meet specific covenants throughout the duration of
this agreement, the most restrictive of which is that the Company shall not have
a net loss (i) of greater than $1,000,000 for any fiscal quarter or (ii) nor in
any two consecutive fiscal quarters, or (iii) an annual loss in excess of
$1,800,000.  In addition, the Company may not declare cash dividends. This
agreement expires on October 31, 1996.  Available borrowings under this
agreement are subject to a borrowing base formula predicated on qualified
receivables as defined and are collateralized by substantially all assets of the
Company.  At June 30, 1995, no amounts were outstanding under this agreement and
the Company had $7,549,000 available under the borrowing base formula.

Long-term debt at June 30, 1994 and 1993, consisted of the following:

Effective July 1,  1992, the TMI Group adopted Statement of Financial Accounting
Standards (SFAS) No. 109, "Accounting for Income Taxes" (SFAS 109).  Effective
July 1, 1993, Sequoia Systems, Inc. adopted SFAS No. 109, "Accounting for Income
Taxes". For the TMI Group the benefit of adopting the statement, $171,000, was
recorded as a cumulative effect of change in accounting for income taxes in the
accompanying financial statements in fiscal 1993.  The impact of Sequoia
Systems, Inc. adoption was immaterial to the financial statements in fiscal
1994.

</TABLE>

The Tax Reform Act of 1986 (the Act), enacted in October 1986, limits the amount
of net operating loss carryforwards that companies may utilize in any one year
in the event of cumulative changes in ownership in excess of 50%, as defined in
the Act, which has limited the Company's ability to utilize in any one year the
net operating loss carryforwards incurred prior to the change in ownership
occurring upon the Company's initial public offering. The Company estimates that
the total net operating loss carryforward subject to this limitation is
approximately $23,000,000. The utilization of the available net operating loss
carryforwards and general business credit carryforwards generated prior to the
ownership change is limited to approximately $2,700,000 in each year subsequent
to the change in ownership until fiscal 2002, at which time the unused net
operating loss carryforwards will expire. These carryforwards are subject to
review and possible adjustment by the Internal Revenue Service. The Company's
net operating loss and general business credit carryforwards at June 30, 1995,
were approximately $44,500,000 ($21,500,000 unrestricted) and $2,800,000,
respectively.  Included with-in the net operating losses is approximately $4.6
million of Incentive Stock Option deductions.  This deduction when utilized will
be a direct credit to stockholders' equity and will not benefit the income
statement.

     A.  Common and Preferred Stock

The Company has 35,000,000 and 12,500,000 authorized shares of common and
preferred stock, respectively at June 30, 1995.  There were 25,000,000 and
12,500,000 authorized shares of common and preferred stock at June 30, 1994.  No
shares of preferred stock were issued or outstanding at June 30, 1995, or 1994.
The Company has reserved 3,700,000 authorized shares of common stock for
issuance under the Company's options plans, 750,000 authorized shares of common
stock for issuance under the 1993 employee stock purchase plan, 131,000 shares
for issuance under the 1991 outside directors' stock option plan, and 150,000
shares for issuance under the 1995 outside directors stock option plan.

On October 27, 1993, the Company issued 1,047,418 shares of Series A Convertible
Preferred Stock in settlement of the class action litigation.  Subsequently,
holders of 264,435 shares of preferred stock converted, at their option, such
shares into the same number of common shares.  The remaining 782,983 shares of
Series A Convertible Preferred Stock were automatically converted to the same
number of common shares on March 15, 1994, in accordance with a mandatory
conversion clause in the class action settlement agreement.


     B.  Stock Option Plans

The Company has two employee stock option plans: the 1986 Incentive Stock Option
Plan (the Incentive Plan) and the 1986 Supplemental Stock Option Plan (the
Supplemental Plan). The Incentive Plan provides for the grant of incentive stock
options to officers and employees of the Company at a price no less than the
fair market value on the date of the grant. The Supplemental Plan provides for
the grant of nonqualified stock options to employees and consultants at no less
than 85% of the fair market value on the date of grant. Options expire 10 years
from the date of grant or, if applicable, three months after termination of the
optionee's employment or other applicable relationship with the Company.

In fiscal 1990, the Company established the 1990 outside directors' stock option
plan (the 1990 Directors' Plan) which provides for the issuance of nonqualified
stock options at a price no less than the fair market value on the date of grant
to members of the Company's Board of Directors who are not employees of the
Company. An aggregate of 131,000 shares of common stock was reserved for
issuance under the 1990 Directors' Plan. The options expire upon the earlier of
10 years from the date of grant or six months after the director ceases to be a
director of the Company. This plan expired on June 7, 1995.  The 131,000 shares
allocated to the plan are available for allocation to other 1995 plans at the
Board of Directors discretion.

In fiscal 1995, the Company established the 1995 outside directors' stock option
plan (the 1995 Directors' Plan).  The terms of the 1995 Plan are identical to
the 1990 Directors' Plan.  An aggregate of 150,000 shares of common stock was
reserved for issuance under the 1995 Directors' Plan.  This plan expires on 
July 1, 1999.

During 1993, the Company canceled certain options to employees and directors and
reissued options, with similar terms, to employees and directors with an
exercise price of $2.25, the fair market value at the date of grant.

     B.   Legal Proceedings

In 1992 the Company was named a defendant to a class action suit brought in the
United States District Court of Massachusetts.   The plaintiffs purported to
represent a class of persons who purchased the common stock of the Company
between July 29, 1991 and December 11, 1992 and alleged that the Company
violated (S)10 (b) of the Securities and Exchange Act of 1934 and committed
common law fraud by materially overstating its revenue and income for the fiscal
quarter ended September 30, 1991, thereafter failing to disclose the alleged
need to restate the Company's revenue and income for that fiscal quarter and by
agreeing with certain revenue and earnings projections for the Company made by
financial analysts.   On July 30, 1993, the Company entered into a settlement by
which all claims asserted by the plaintiffs against the Company, Arthur Andersen
& Co., the Company's former auditors, and former executives of the Company were
settled.  The global settlement provided for a cash payment totaling $3,125,000,
of which $1,075,000 was paid by the Company and $2,050,000 was paid by the
Company's insurance carrier and the other defendants in the class action
litigation.  In addition, the Company issued to the plaintiffs $2,875,000 in
face amount of a new class of preferred stock, bearing dividends at a rate of 7%
per year, payable annually, and convertible into common stock at a conversion
price equal to 110% of the average trading price of the Company's common stock
during a specified period prior to the effective date.

The preferred stock was automatically converted to common stock according to its
terms on March 15, 1994 on which date the closing price of the Company's common
stock was $6.0625 per share. The agreement was approved by the District Court on
September 10, 1993.

On May 8, 1992, the Securities and Exchange Commission notified the Company that
the Commission had begun an informal investigation with respect to the Company's
revenue recognition policies. On September 28, 1992, after receiving certain
documentation and information requested from the Company, the Commission
notified the Company that the Commission had entered a formal order of
investigation with respect to these matters. On February 16, 1995, the Company
and the Commission entered into a settlement agreement, subsequently approved by
the U.S. District Court for the District of Columbia, pursuant to which the
Company consented to the issuance of an injunction against it prohibiting future
violations of certain securities laws and regulations, but the Company was not
required to pay any fines or make any other payments.

         notwithstanding, no Employee shall be granted an option to
         participate in the Plan:

              5.   Participation.
                   -------------

              All eligible Employees will become participants in an
         Offering on the applicable Offering Commencement Date.  Payroll
         deductions for a participant shall commence on the Offering
         Commencement Date applicable to the Offering (or as soon
         thereafter as may be determined by the Company in its discretion)
         and shall end on the Offering Termination Date applicable to such
         Offering, unless sooner terminated pursuant to Paragraph 10.

              6.   Payroll Deductions.
                   ------------------

                   (a)  Participants may elect to have amounts withheld
         from Monetary Compensation by completing an authorization for a
         payroll deduction (an "Authorization") on the form provided by the
         Company and delivering it to the Company.  At the time a
         participant files his or her Authorization for a payroll
         deduction, the participant shall elect to have deductions made
         from his or her pay on each payday during the time he or she is a
         participant in an Offering at the rate of 0, 1, 2, 3, 4, 5, or 6%,
         of his or her Monetary Compensation.  The aggregate amount of a
         participant's payroll deductions for any Offering Period is
         referred to herein as the "Authorized Deduction."  An
         Authorization filed with respect to any Offering shall also be
         deemed to be an Authorization with respect to any subsequent
         Offering; provided, that (i) the participant may amend his or her
         Authorization with respect to any subsequent Offering by filing a
         new Authorization at least seven days prior to the Offering
         Commencement Date of such subsequent Offering, and (ii) the
         participant may withdraw his or her payroll deductions from the
         Plan at any time pursuant to Section 8(b).  If a participant has
         not filed an Authorization with respect to an Offering (including
         an Authorization deemed to apply to any Offering pursuant to the
         preceding sentence) on or before the date(s) specified by the
         Company, he or she shall be deemed to have filed an Authorization
         election to withhold 0% of any Monetary Compensation.

                   (b)  All payroll deductions made for a participant shall
         be credited to his or her account under the Plan.  Except as
         provided in Section 6(d), a participant may not make any separate
         cash payment into such account.

                   (c)  Except as provided in Paragraph 8(b) or
         Paragraph 10, a participant may not make changes to the rate of
         deductions from his or her Monetary Compensation during an
         Offering Period.

                   (d)  Notwithstanding the foregoing, the Company may
         permit and/or require participants who are not residents of the
         United States to make one or more lump-sum contributions to the
         Plan in lieu of contributions through payroll deductions, such

                                         -3-
<PAGE>
 
         number of contributions and the manner of making such
         contributions required of any such participant shall be determined
         by the Committee (as defined in Section 13 hereof) or such other
         officer of the Company as the Committee shall designate.  No such
         employee shall participate in the Plan, however, unless such
         employee shall have filed an Authorization on or before the date
         on which other employees must file Authorizations.  Any lump-sum
         contributions shall be treated as payroll deductions for all
         purposes under the Plan.

              7.   Granting of Options.
                   -------------------

                   (a)  With respect to each Offering, a participating
         Employee shall be deemed to have been granted, on the applicable
         Offering Commencement Date, an option (the "Option") to purchase a
         maximum number of shares of Common Stock determined as follows:
         85% of the market value of a share of Common Stock on such
         Offering Commencement Date shall be divided into an amount equal
         to 6% of such Employee's Monetary Compensation for the period of
         such Offering, provided that in no event shall an Employee be
         granted an Option to purchase more than 500 shares of Common Stock
         with respect to each Offering.  The market value of the Common
         Stock shall be determined as provided in paragraph (b) below.

                   (b)  With respect to each Offering, the purchase price
         of a share of Common Stock purchased with the Authorized Deduction
         (the "Option Exercise Price") shall be the lower of:

                       (i)   85% of the composite closing price of the
                   Common Stock on the over the counter market as reported
                   by NASDAQ in "The Wall Street Journal" on the Offering
                   Commencement Date applicable to such Offering (or on the
                   next regular business day on which shares of the Common
                   Stock shall be traded in the event that no such shares
                   shall have been traded on the Offering Commencement
                   Date); or

                      (ii)   85% of the composite closing price of the
                   Common Stock on the over the counter market as reported
                   by NASDAQ in "The Wall Street Journal" on the Offering
                   Termination Date applicable to such Offering (or on the
                   next regular business day on which shares of the Common
                   Stock shall be traded in the event that no such shares
                   shall have been traded on the Offering Termination
                   Date).

              8.   Exercise of Options.
                   -------------------

              With respect to each Offering during the term of the Plan:

                   (a)  Unless a participant gives written notice of
         withdrawal to the Company as provided in Paragraph 10, his or her

                                         -4-
<PAGE>
 
         Option will be deemed to have been exercised automatically on the
         Offering Termination Date applicable to such Offering for the
         purchase of the number of whole shares of Common Stock which the
         Authorized Deduction in his or her account on such date will
         purchase at the applicable Option Exercise Price (but not in
         excess of the number of shares for which an Option has been
         granted the employee pursuant to Paragraph 7(a)).  No fractional
         shares will be issued.  Any excess in such participant's account
         on such date will either, (i) to the extent it is attributable to
         amounts that would have purchased fractional shares only, with the
         consent of such participant (and with the consent of the Company,
         which may be withheld in its sole discretion), remain in such
         participant's account under the Plan or under a successor plan, if
         any, or (ii) be returned to him or her; provided that any excess
         returned will not be credited with any interest.

                   (b)  By written notice to the Company at any time prior
         to the applicable Offering Termination Date, a participant may
         elect to withdraw all (but not less than all) of the accumulated
         payroll deductions in his or her account at such time.

              9.   Delivery of Share Certificates.
                   ------------------------------

              As promptly as practicable after the Offering Termination
         Date with respect to each Offering, the Company will deliver to
         each participant, as appropriate, a certificate or certificates
         representing the shares of Common Stock purchased upon the
         exercise of such participant's Option.

              10.  Withdrawal.
                   ----------

                   (a)  As indicated in Paragraph 8(b), a participant may
         withdraw payroll deductions credited to his or her account at any
         time prior to the applicable Offering Termination Date by giving
         written notice of withdrawal to the Company.  All of the
         participant's payroll deductions credited to his or her account
         will be paid to the participant promptly after receipt of such
         notice of withdrawal, and no further payroll deductions will be
         made with respect to such participant during such Offering.  The
         Company may, at its option, treat any attempt by an employee to
         borrow on the security of accumulated payroll deductions as an
         election to withdraw such deductions.

                   (b)  A participant's withdrawal from any Offering will
         not have any effect upon his or her eligibility to participate in
         any succeeding Offering or in any similar plan which may hereafter
         be adopted by the Company; provided, however, that an Employee who
         is subject to Section 16 of the Securities Exchange Act of 1934,
         as amended, who withdraws his or her payroll deductions prior to
         the end of an Offering Period may not participant in the Plan or
         in any similar successor plan for a period of at least six months
         from the date of such withdrawal.

                   (c)  Upon termination of the participant's employment
         for any reason, including retirement but excluding death or
         disability while in the employ of the Company, the payroll
         deductions credited to his or her account will be returned to the
         participant or, in the case of his or her death subsequent to the
         termination of employment, to the person or persons entitled
         thereto under Paragraph 14.

                   (d)  Upon termination of the participant's employment
         because of death or disability, the participant or his or her
         beneficiary (as defined in Paragraph 14) shall have the right to
         elect, by written notice given to the Company prior to the
         expiration of the period of 30 days commencing with the date of
         the death or disability of the participant, either:

                       (i)   to withdraw all of the payroll deductions
                   credited to the participant's account under the Plan; or

                      (ii)   to exercise the participant's option for the
                   purchase of Common Stock on the Offering Termination
                   Date next following the date of the participant's death
                   or disability for the purchase of the number of full
                   shares of Common Stock which the accumulated payroll
                   deductions in the participant's account at the date of
                   the participant's death or disability will purchase at
                   the applicable Option Exercise Price, and any excess in
                   such account will be returned to the participant or said
                   beneficiary.

              In the event that no such written notice of election shall be
         duly received by the Company, the participant or beneficiary shall
         automatically be deemed to have elected to withdraw the payroll
         deductions credited to the participant's account at the date of
         the participant's death or disability, and the same will be paid
         promptly to the participant or said beneficiary.

              11.  Interest.
                   --------

              No interest will be paid or allowed on any money paid into
         the Plan or credited to the account of any participant employee
         except as specifically set forth in this Plan.  

              12.  Stock.
                   -----

                   (a)  The maximum number of shares of Common Stock which
         shall be made available for sale under the Plan during any
         Offering under the Plan shall be 62,500 shares, subject in each
         case to adjustment upon changes in capitalization of the Company
         as provided in Paragraph 17.  If the total number of shares for
         which Options are exercised on any Offering Termination Date in
         accordance with Paragraph 8 exceeds 62,500, the Company shall make

                                         -6-
<PAGE>
 
         a pro rata allocation of the shares available for delivery and
         distribution in as nearly a uniform manner as shall be practicable
         and as it shall determine to be equitable, and the balance of
         payroll deductions credited to the account of each participant
         under the Plan shall be returned to him or her as promptly as
         possible.  If fewer than 62,500 shares are purchased during any
         given Offering under the Plan, the amount not purchased may be
         carried over to and made available during the next and other
         subsequent Offerings under the Plan.

                   (b)  No participant will have any interest in Common
         Stock covered by his or her Option until such Option has been
         exercised.

                   (c)  The Common Stock to be delivered to a participant
         under the Plan will be registered in the name of the participant,
         or, if the participant so directs, by written notice to the
         Company prior to the Offering Termination Date applicable thereto,
         in the names of the participant and one such other person as may
         be designated by the participant, as joint tenants with rights of
         survivorship, to the extent permitted by applicable law.

                   (d)  The Board of Directors of the Company may, in its
         discretion, require as conditions to the Exercise of any Option
         that the shares of Common Stock reserved for issuance upon the
         exercise of the Option shall have been duly listed, upon official
         notice of issuance, on the over the counter market as reported by
         NASDAQ, and that either:

                       (i)   a registration statement under the Securities
                   Act of 1933, as amended (the "Securities Act"), with
                   respect to said shares shall be effective; or

                      (ii)   the Company shall have received the opinion of
                   counsel acceptable to the Company to the effect that the
                   issuance of such shares is exempt from all registration
                   requirements under the Securities Act.

              13.  Administration.
                   --------------

              The Plan shall be administered by the Compensation Committee
         (the "Committee") appointed by the Board of Directors of the
         Company.  The officer of the Company charged by the Committee with
         day-to-day administration of the Plan shall, for matters involving
         the Plan, be an ex officio member of the Committee.  The
         interpretation and construction of any provision of the Plan and
         the adoption of all rules and regulations for administering the
         Plan shall be made by the Committee; provided, however, that any
         such interpretation, rule or regulation adopted by the Committee
         may be subsequently altered, amended or repealed by the Committee
         or the Board of Directors.  All such interpretations, rules and
         regulations made by the Committee and approved by the Board of

                                         -7-
<PAGE>
 
         Directors with respect to any matter or provision contained in the
         Plan shall be final, conclusive and binding upon the Company and
         upon all participants, their heirs or legal representatives.  The
         Company shall indemnify Committee members, to the fullest extent
         permitted by applicable statute, for any expenses incurred in
         defending a civil or criminal action or proceeding arising out of
         such member's actions with respect to the administration of the
         Plan, in advance of the final disposition of such action or
         proceeding, upon receipt of an undertaking by the member
         indemnified to repay such payment if such member shall be
         adjudicated not to have, acted in good faith in the reasonable
         belief that such members actions were in the best interests of the
         Company.

              14.  Designation of Beneficiary.
                   --------------------------

              A participant may file a written designation of a beneficiary
         who is to receive any shares of Common Stock and/or cash in the
         event of the death of the participant prior to the delivery of
         such shares or cash to the participant.  Such designation of
         beneficiary may be changed by the participant at any time by
         written notice to the Company.  Within 30 days after the
         participant's death, the beneficiary may, as provided in Paragraph
         l0(d), elect to exercise the participant's Option when it becomes
         exercisable on the Offering Termination Date of the then current
         Offering.  Upon the death of a participant and upon receipt by the
         Company of proof of the identity and existence at the
         participant's death of a beneficiary validly designated by the
         participant under the Plan, and notice of election of the
         beneficiary to exercise the Option, the Company shall deliver such
         stock and/or cash to such beneficiary.  In the event of the death
         of a participant and in the absence of a beneficiary validly
         designated under the Plan designated under the Plan who is living
         at the time of such participant's death, the Company shall deliver
         such stock and/or cash to the executor or administrator of the
         estate of the participant, or if no such executor or administrator
         has been appointed (to the knowledge of the Company), the Company,
         in its discretion, may deliver such stock and/or cash to the
         spouse or to any one or more dependents of the participant as the
         Company may designate.  No beneficiary shall prior to the death of
         the participant by whom he has been designated acquire any
         interest in the stock or cash credited to the participant under
         the Plan.

              15.  Transferability.
                   ---------------

              Neither payroll deductions credited to a participant's
         account nor any rights with regard to the exercise of an Option or
         to receive stock under the Plan may be assigned, transferred,
         pledged or otherwise disposed of in any way by the participant

                                         -8-
<PAGE>
 
         otherwise than by will or the laws of descent and distribution.
         Any such attempted assignment, transfer, pledge, or other
         disposition shall be without effect, except that the Company may
         treat such act as an election to withdraw funds in accordance with
         Paragraph 8(b).

              16.  Use of Funds.
                   ------------

              All payroll deductions received or held by the Company under
         this Plan may be used by the Company for any corporate purpose,
         and the Company shall not be obligated to segregate such payroll
         deductions.

              17.  Effect of Changes of Common Stock.
                   ---------------------------------

              In the event of any changes of outstanding shares of the
         Common Stock by reason of stock dividends, subdivisions,
         combinations and the like, the aggregate number and class of
         shares available under this Plan and the Option Exercise Price per
         share shall be appropriately adjusted by the Board of Directors of
         the Company, whose determination shall be conclusive.  Any such
         adjustments may provide for the elimination of any fractional
         shares which would otherwise become subject to any Option. 

              18.  Amendment or Termination.
                   ------------------------

              The Board of Directors of the Company may at any time
         terminate or amend the Plan.  Except as hereinafter provided,
         however, no such termination may affect Options previously
         granted, and no such amendment may make any change in any Option
         previously granted which would adversely affect the rights of any
         participant.  In addition, no amendment may be made without prior
         approval of the stockholders of the Company if such amendment
         would (a) materially increase the benefits accruing to
         participants under the Plan or (b) materially modify the
         requirements as to eligibility for participation under the Plan.

              19.  Notices.
                   -------

              All notices or other communications by a participant to the
         Company under or in connection with the Plan shall be deemed to
         have been duly given when received by the Company's Human
         Resources Department.

              20.  Merger or Consolidation.
                   -----------------------

              If the Company shall at any time merge into or consolidate
         with another corporation and the Company is the surviving entity,
         the holder of each Option then outstanding will thereafter be
         entitled to receive at the next Offering Termination Date upon the
         exercise of such Option for each share as to which such Option
         shall be exercised the securities or property to which a holder of

                                         -9-
<PAGE>
 
         one share of the Common Stock was entitled upon and at the time of
         such merger or consolidation, and the Board of Directors of the
         Company shall take such steps in connection with such merger or
         consolidation as the Board of Directors shall deem necessary to
         assure that the provisions of Paragraph 17 shall thereafter be
         applicable, as nearly as reasonably may be, in relation to the
         said securities or property as to which such holder of such Option
         might thereafter be entitled to receive thereunder.  In the event
         of a merger or consolidation in which the Company is not the
         surviving entity, or of a sale of all or substantially all of the
         assets of the Company, the Plan shall terminate, and all payroll
         deductions credited to participants' accounts shall be returned to 
         them.

              21.  Approval of Stockholders. 
                   ------------------------

              The Plan has been adopted by the Board of Directors of the
         Company, but shall be void and of no effect unless it is approved
         by the stockholders of the Company at the 1993 annual meeting.

              22.  Registration and Qualification of the Plan Under
                   ------------------------------------------------
                   Applicable Securities Laws.
                   --------------------------

              No Option shall be granted under the Plan until such time as
         the Company has qualified or registered the shares which are
         subject to the Options under the applicable state and federal
         securities laws to the extent required by such laws.


                         APPROVED BY THE BOARD OF DIRECTORS ON JUNE 11,

                      1995 OUTSIDE DIRECTORS' STOCK OPTION PLAN
                      -----------------------------------------

         1.   Purpose.
              -------

              The purpose of this 1995 Outside Directors' Stock Option Plan
         (the "Plan") of Sequoia Systems, Inc. (the "Company") is to
         encourage stock ownership in the Company by outside directors of
         the Company whose continued services are considered essential to
         the Company's future success and to provide them with a further
         incentive to remain as directors of the Company.

         2.   Administration.
              --------------

              The Board of Directors of Sequoia Systems (the "Board") shall
         supervise and administer the Plan.  Grants of stock options under
         the Plan and the amount and nature of the options to be granted
         shall be automatic in accordance with Section 5.  However, all
         questions concerning interpretation of the Plan or any options
         granted under it shall be resolved by the Board and such
         resolution shall be final and binding upon all persons having an
         interest in the Plan.

         3.   Participation in the Plan.
              -------------------------

              Directors of the Company who are not employees of the Company
         or any subsidiary of the Company ("outside directors") shall be
         eligible to receive options under the Plan.

         4.   Stock Subject to the Plan.
              -------------------------

              (a)  The maximum number of shares of the Company's Common
         Stock, par value $.40 per share ("Common Stock"), which may be
         issued under the Plan shall be 150,000 shares, subject to
         adjustment as provided in Section 7.

              (b)  If any outstanding option under the Plan for any reason
         expires or is terminated without having been exercised in full,
         the shares covered by the unexercised portion of such option shall
         again become available for issuance pursuant to the Plan.

              (c)  All options granted under the Plan shall be nonstatutory
         options not under Section 422 of the Internal Revenue Code of
         1986, as amended (the "Code").
<PAGE>
 
         5.   Terms, Conditions and Form of Options.
              -------------------------------------

              Each option granted under the Plan shall be evidenced by a
         written agreement in such form as the Chairman of the Board of
         Directors shall from time to time approve, which agreement shall
         comply with and be subject to the following terms and conditions:

              (a)  Option Grant Dates and Shares Subject to Option.
                   -----------------------------------------------

                   (i)  Initial Grants.  A fully vested option to purchase
                        --------------
         12,000 shares of Common Stock shall be granted automatically to
         each person who becomes an outside director of the Company after
         the date of the Board's adoption of the Plan.

                  (ii)  Subsequent Grants.  A fully vested option to
                        -----------------
         purchase 2,500 shares of the Common Stock shall be granted
         automatically to each outside director on each July 1 from July 1,
         1995 through and including July 1, 1999, provided, that he or she
         is an eligible director on the date of grant of such option.

              (b)  Option Exercise Price.  The option exercise price per
                   ---------------------
         share for each option granted under the Plan shall be equal to the
         fair market value per share of Common Stock on the date of grant,
         which shall be determined as follows:  (i) if the Common Stock is
         listed on the Nasdaq National Market or another nationally
         recognized exchange or trading system as of the date on which a
         determination of fair market value is to be made, the fair market
         value per share shall be deemed to be the last reported sale price
         per share of Common Stock thereon on such date (or, if no such
         price is reported on such date, such price on the nearest
         preceding date on which such a price is reported); and (ii) if the
         Common Stock is not listed on the Nasdaq National Market or
         another nationally recognized exchange or trading system as of the
         date on which a determination of fair market value is to be made,
         the fair market value per share shall be deemed to be the book
         value per share of the Common Stock as of the end of the most
         recent fiscal quarter preceding such date.

              (c)  Options Non-Transferable.  Each option granted under the
                   ------------------------
         Plan by its terms shall not be transferable by the optionee
         otherwise than by will or the laws of descent and distribution or
         pursuant to a qualified domestic relations order (as defined in
         the Code), and shall be exercised during the lifetime of the
         optionee only by the optionee or his or her legal representative.
         No option or interest therein may be transferred, assigned,
         pledged or hypothecated by the optionee during his or her

                                        -2-
<PAGE>
 
         lifetime, whether by operation of law or otherwise, or be made
         subject to execution, attachment or similar process.

              (d)  Exercise Period.  Each option may be exercised at any
                   ---------------
         time and from time to time, in whole or in part, prior to the
         tenth anniversary of the date of grant, except that no option may
         be exercised more than six months after the optionee ceases to
         serve as a director of the Company.

              (e)  Termination.  Each option shall terminate, and may no
                   -----------
         longer be exercised, on the earlier of (i) the date 10 years after
         the date of grant or (ii) the date one year after the optionee
         ceases to serve as a director of the Company for any reason,
         whether by death, resignation, removal or otherwise.

              (f)  Exercise Procedure.  An option may be exercised only by
                   ------------------
         written notice to the Company at its principal office accompanied
         by payment in cash of the full consideration for the shares as to
         which the option is exercised.

              (g)  Exercise by Representative Following Death of Director.
                   ------------------------------------------------------
         An optionee, by written notice to the Company, may designate one
         or more persons (and from time to time change such designation),
         including his or her legal representative, who, by reason of the
         optionee's death, shall acquire the right to exercise all or a
         portion of the option.  If the person or persons so designated
         wish to exercise any portion of the option, they must do so within
         the term of the option as provided herein.  Any exercise by a
         representative shall be subject to the provisions of the Plan.

         6.   Limitation of Rights.
              --------------------

              (a)  No Right to Continue as a Director.  Neither the Plan,
                   ----------------------------------
         nor the granting of an option nor any other action taken pursuant
         to the Plan, shall constitute or be evidence of any agreement or
         understanding, express or implied, that the optionee shall be
         entitled to continue as a director for any period of time.

              (b)  No Stockholder Rights for Options.  An optionee shall
                   ---------------------------------
         have no rights as a stockholder with respect to the shares covered
         by his or her option until the date of the issuance to him or her
         of a stock certificate therefor, and no adjustment will be made
         for dividends or other rights (except as provided in Section 7)
         for which the record date is prior to the date such certificate is
         issued.

              --------------------------------------------------------
              Related Transactions.
              --------------------

              If, through or as a result of any merger, consolidation,
         reorganization, recapitalization, reclassification, stock
         dividend, stock split, reverse stock split or other similar
         transaction, (i) the outstanding shares of Common Stock are
         exchanged for a different number or kind of securities of the
         Company or of another entity, or (ii) additional shares or new or
         different shares or other securities of the Company or of another
         entity are distributed with respect to such shares of Common
         Stock, the Board shall make an appropriate and proportionate
         adjustment in (x) the maximum number and kind of shares reserved
         for issuance under the Plan, (y) the number and kind of shares or
         other securities subject to then outstanding options under the
         Plan, and/or (z) the price for each share subject to any then
         outstanding options under the Plan (without changing the aggregate
         purchase price for such options), to the end that each option
         shall be exercisable, for the same aggregate exercise price, for
         such securities as such optionholder would have held immediately
         following such event if he or she had exercised such option
         immediately prior to such event.  No fractional shares will be
         issued under the Plan on account of any such adjustments.

         8.   Modification, Extension and Renewal of Options.
              ----------------------------------------------

              The Board shall have the power to modify or amend outstanding
         options; provided, however, that no modification or amendment may
         (i) have the effect of altering or impairing any rights or
         obligations of any option previously granted without the consent
         of the optionee, or (ii) modify the number of shares of Common
         Stock subject to the option (except as provided in Section 7).

         9.   Termination and Amendment of the Plan.
              -------------------------------------

              The Board may suspend, terminate or discontinue the Plan or
         amend it in any respect whatsoever; provided, however, that
         without approval of the stockholders of the Company, no amendment
         may (i) increase the number of shares subject to the Plan (except
         as provided in Section 7), (ii) materially modify the requirements
         as to eligibility to receive options under the Plan, or
         (iii) materially increase the benefits accruing to participants in
         the Plan; and provided further that the Board may not amend the
         provisions of Sections 3 or 5, insofar as they relate to the
         amount, price and timing of options to be granted hereunder, more
         frequently than once every six months, other than to comply with
         changes in the Code or the rules thereunder.

         options granted under the Plan shall be null and void if the Plan
         is not so approved by the Company's stockholders.

                       PICK - SEQUOIA LICENSE AGREEMENT

     This Second Amendment to the Pick - Sequoia Open Architecture License
Agreement is entered into effective 8-11-95, between Pick Systems ("Pick")
and Sequoia Systems, Inc. ("Sequoia").

                                   RECITALS


     A.  Pick and Concurrent Operating Systems Technology ("Concurrent
Operating") entered into an Open Architecture License Agreement (the "License
Agreement") on October 10, 1986. By virtue of its purchase of Concurrent
Operating, Sequoia Systems, Inc. assumed all of Concurrent Operating's rights
and duties under the License Agreement.

     B.  Pick and Sequoia now wish to enter into this Second Amendment to the
License Agreement.

     Now, therefore, for valuable consideration, the sufficiency of which is
acknowledged by the parties, Pick and Sequoia hereby amend the License
Agreement as follows:


1.   A new Section 25 is hereby added to the License Agreement, as follows:


     Operating Systems File Interface
     --------------------------------

     (a)  Pick hereby grants to Licensee non-exclusive license to use Pick's
Operating Systems File Interface, including both source and object code
therefor, and all revisions, enhancements and upgrades thereto developed by
Pick, (collectively, "OSFI") subject to the terms and conditions of this
Agreement, except as specified in this Section 25.

     (b)  For such license, Licensee shall pay Pick license fees based on the
aggregate number of Seats on which Licensee sub-licenses the use of OSFI to
its sub-licensees of Licensed Systems at the rate of $20.00 each for the first
5000 Seats, $10.00 for each of the next 5000 Seats and $5.00 for each Seat
over 10,000 Seats. Such payments shall be subject, however, to an aggregate
maximum of $225,000, beyond which no further license fees with respect to the
OSFI shall be due. No other license fees or royalties shall be due in respect of
OSFI. For purposes of licensing OSFI, "Seats" shall be defined as the number
of concurrently active users of OSFI software.

     (c)  Licensee and Pick agree to cooperate with each other in the continued
development of OSFI, to share the results of such efforts and to furnish each
other with all upgrades and other OSFI product developments each produces

                               FIRST AMENDMENT TO

                       PICK - SEQUOIA LICENSE AGREEMENT


          This First Amendment to the Pick - Sequoia Open Architecture License 
Agreement is entered into effective Feb. 2, 1995, between Pick Systems ("Pick") 
and Sequoia Systems, Inc. ("Sequoia").


                                   RECITALS
                                   --------


          A.  Pick and Concurrent Operating Systems Technology ("Concurrent
Operating") entered into an Open Architecture License Agreement (the "License
Agreement") on October 10, 1986. By virtue of its purchase of Concurrent
Operating, Sequoia Systems, Inc. assumed all of Concurrent Operating's rights
and duties under the License Agreement.


          B.  Pick and Sequoia now wish to enter into this First Amendment to 
the License Agreement.


          Now, therefore, for valuable consideration, the sufficiency of which
is acknowledged by the parties, Pick and Sequoia hereby amend the License
Agreement as follows:


                                  AMENDMENT
                                  ----------


          1.  Limitation on License. Subparagraph 4(b) which excludes the use
              ---------------------
and sub-licensing of the Pick Systems is deleted in its entirety. All recurring
references to "Excluded" systems are also deleted.


          2.  Qualified Configuration. The defined term "Qualified
              -----------------------
Configuration" set out in Paragraph 1.7 of the License Agreement is amended to
read as follows:
<PAGE>
 
          1.7  "Qualified Configuration" shall mean a Licensee hardware
          configuration which is based only on the microprocessor defined in
          Exhibit "A" hereto. The Qualified Configuration shall include not only
          the most current version of the microprocessor, but each subsequent
          version by the same manufacturer which incorporates or exhibits the
          same instruction set and is marketed by the manufacturer as a
          sequential upgrade to the current version. The Qualified Configuration
          shall include a central processing unit, random access memory, and a
          hard disk drive as inherent hardware components.


          3.  Licensed System. The term "Licensed System" as defined in
              ---------------
Paragraph 1.5 of the License Agreement is amended to read as follows:


          1.5 "Licensed System" shall mean a single copy of the Pick System, as
          modified by an Implementation, to be used, delivered or sub-licensed
          in object code form only, solely on, and bundled as an integral part
          of a single "Qualified Configuration" designated by location, type and
          serial number.


          4.  Effect of Amendment. Except as specifically modified hereby, the
              -------------------
License Agreement and its terms, conditions and definitions shall remain in full
force and effect, and shall govern this First Amendment.

                      maximum cumulative royalty of $1,000,000 U.S. Such royalty

                      incurred for the audit. If such audit reflects an over

               amounts received by Seller, after such deduction or withholding,

               authority on or with respect to this Agreement, the costs of such
               taxes or duties shall be borne by Buyer. In the event that such
               taxes or duties are legally imposed initially on Seller or Seller

               promptly reimbursed by Buyer for such taxes or duties plus any

               pay any taxes on income or profit recognized by Seller.

     1.  Defendant Sequoia Systems, Inc. ("Sequoia"), having been served with 
the Complaint for Permanent Injunction and Other Equitable Relief ("Complaint"),
and having entered a general appearance admits the service of the Complaint upon
it and consents to the jurisdiction of this Court over it and over the subject
matter of this action.

     2.  Sequoia, without admitting or denying any of the allegations of the
Complaint, except as to jurisdiction which it admits, hereby consents, solely
for the purposes of this action, to the entry of the Final Judgment of Permanent
Injunction as to Defendant Sequoia Systems, Inc. ("Final Judgment") in the form
annexed hereto and incorporated by reference herein, permanently restraining and
enjoining Sequoia from engaging in conduct violative of Sections 10(b), 13(a),

240.13a-13] thereunder.

     3.  As set forth above, Sequoia consents to the entry of the Final 
Judgment, without admitting or denying any of the allegations of the Complaint,
except as to jurisdiction which it admits. Sequoia understands that it is the
Commission's policy, set forth in 17 C.F.R. (S) 202.5(e), not to permit a
defendant to consent to entry of a judgment while denying the allegations in the
Complaint. Sequoia further understands that the Commission's acceptance of this
Consent in this matter is based upon its compliance with this policy.

     4.  Sequoia waives the filing of an answer and waives the entry of findings
of fact and conclusions of law pursuant to Rule 52 of the Federal Rules of Civil
Procedure.

     5.  Sequoia waives any right it may have to appeal from the entry of the
annexed Final Judgment.

     6.  Sequoia enters into this Consent and Undertakings ("Consent")
voluntarily and of its own accord and represents that no offers, promises,
inducements, or threats of any kind have been made by the Commission or any
member, officer, agent, employee, or representative thereof to induce it to
enter into this Consent.

     7.  Sequoia undertakes and agrees to cooperate with the Commission and to
provide to the Commission discovery, including documentary evidence, and to
provide truthful information at any interview, deposition, and any judicial or
investigative (whether

                                      2
<PAGE>
 
formal or informal) or administrative proceeding related to or in connection
with the matters alleged in, or arising out of, the Complaint, or any of the
other defendants in SEC v. Sequoia Systems, Inc., as the Commission may seek
                    ----------------------------
or require; and that it will do so at the request of the Commission or its
staff, upon reasonable request and upon service of a subpoena on either the
General Counsel or Corporate Secretary of Sequoia, by First Class Mail or any
other method the Commission may choose.

     8.  Sequoia agrees that this Consent shall be incorporated by reference in
the Final Judgment with the same force and effect as if fully set forth therein.

     9.  Sequoia agrees that it will not oppose the enforcement of the Final
Judgment on the ground, if any exists, that it fails to comply with Rule 65(d)
of the Federal Rules of Civil Procedure, and hereby waives any objection it may
have based thereon.

     10. Sequoia agrees that the Final Judgment may be presented by the
Commission to the Court for signature and entry without further notice.

     11. Sequoia waives service of the Final Judgment entered herein upon it and
agrees that entry of the Final Judgment by the Court and filing with the Clerk
in the District of Columbia will constitute notice to it of the terms and
conditions of the Final Judgment.

     12. Sequoia agrees that this Court shall retain jurisdiction over this
matter for the purpose of enforcing the terms and conditions of the Final
Judgment, for all purposes regarding the

                                      3

     THIS OFFICE LEASE AGREEMENT (this "Lease") dated as of December 11, 1992,
is made between CHEVRON U.S.A. INC., a Pennsylvania corporation ("Landlord"),
and TEXAS MICRO-SYSTEMS, INC., a Texas corporation ("Tenant").

                                   ARTICLE 1

                                   PREMISES


      Section 1.01. Landlord hereby leases to Tenant, and Tenant hereby leases
from Landlord for the Term (as defined below) and subject to the provisions
hereof, to each of which Landlord and Tenant mutually agree, the Premises (as
defined below) 83,428 square feet of Net Rentable Area (as defined below)
located on the first floor (such first floor space shall comprise 32,033 square
feet as shown on Exhibit A-1 hereto ("Existing Space") and 30,703 square feet as
shown on Exhibit A-2 hereto ("Improvement Space") plus 20,692 square feet of Net
Rentable Area in the basement as shown on Exhibit A-3 hereto ("Basement Space")
of the Building now known as 5959 Corporate Drive ("Building"), located in
Houston, Harris County, Texas ("Premises"), which Premises are more
particularly described in the floor plans in Exhibit A hereto, together with its
                                             ---------
appurtenances, including the right to use, in common with others, the lobbies,
entrances, stairs, passenger and freight elevators, offstreet loading areas (for
loading and unloading of materials and supplies), and other public portions of
the Building. Landlord covenants that the main floor lobby, atrium and common
area restrooms located on the first floor will not be unreasonably reduced or
the use thereof be otherwise unreasonably limited except as is necessary for
ordinary maintenance and repair. Landlord further covenants that a vending area
reasonably comparable to the vending area presently existing in the Building
will be maintained in the Building and be accessible to Tenant and Tenant's
employees, provided, however, that Landlord reserves the right to relocate such
vending area to another location in the Building and provided further that
Landlord may reduce the size of such vending area so long as such area continues
to be reasonably usable for its essential purpose by tenants in the Building,
including Tenant and Tenant's employees. The Building is situated on the real
property described in Exhibit B hereto (the "Land").
                      ---------

     Section 1.02. The term "Net Rentable Area", as used herein, shall be the
unit of measurement for space in the Building leased or held for lease to
tenants, and shall mean (a) in the case of a single tenancy floor, all floor
area, measured from the inside surface of the outer glass line of the Building
excluding only the areas ("service areas") used for Building stairs, fire
towers, elevator shafts, flues, vent stacks, pipe shafts, and vertical ducts
(which service areas shall be measured from the midpoint of walls enclosing such
service areas), but including any such service areas which are for the specific
use of the particular
<PAGE>
 
tenant such as special stairs or special elevators, plus an allocation of the
square footage of the Building's "support areas," (support areas defined as the
elevator and mechanical and electrical rooms, maintenance areas and public
areas, and (b) in the case of a floor to be occupied by more than one tenant,
all floor areas within the inside surface of the outer glass line enclosing the
Premises and measured to the midpoint of the walls separating areas leased by or
held for lease to other tenants, or "common areas," (common areas defined as
those areas devoted to corridors, elevator foyers, rest rooms, mechanical rooms,
janitor closets, vending areas and other similar facilities for the use of all
tenants on the particular floor, but including a proportionate part of the
common areas located on such floor, plus an allocation of the support areas of
the Building. No deductions from Net Rentable Area share be made for columns or
projections necessary to the Building. The Net Rentable Area of the Premises has
been calculated on the basis of the foregoing definition, includes the "add-on
factors" of fifteen percent (15%) for the Existing Space and ten percent (10%)
for the Improvement Space, and is stipulated for all purposes hereof to be the
amount stated in Section 1.01. The Net Rentable Area of the Building is to be
determined by Landlord in good faith and supplied to Tenant by Landlord in
writing on or before December 21, 1992; provided, however, that if the Net
Rentable Area is ever thereafter calculated by Landlord to be, or otherwise
established to be, more than such number, then the Net Rentable Area of the
Building shall be adjusted to such higher number for all purposes hereof.

                                   ARTICLE 2

                                     TERM


     Section 2.01. The term of this Lease (the "Term") is sixty six (66) months
beginning on the date of execution of this Lease by Landlord and Tenant (the
"Commencement Date") and, unless sooner terminated or renewed pursuant to the
provisions hereof, ending at midnight on June 11, 1998 (the "Expiration Date").
Regardless of whether construction of Leasehold Improvements (as defined in 
Article 3) in the Premises is completed by the Rental Commencement Date (as
defined in Article 3), the Term shall not be extended for any reason beyond the
Expiration Date. The period between the Commencement Date and the Expiration
Date is sometimes herein referred to as the it "original" Term, and that
portion, if any, of the Term resulting from the exercise of a renewal option
granted in Section 26.01 is sometimes referred to as a "original" Term.

     Section 2.02. Provided Tenant performs all of Tenant's obligations under
this Lease, including the payment of Rent (as defined below), Tenant shall,
during the Term, peaceably and quietly enjoy the Premises without disturbance
from Landlord or any other persons acting by, through or under Landlord;
subject, however, to the terms of this Lease. This covenant and all other
covenants of Landlord in this Lease shall be binding,

                                      -2-
<PAGE>
 
upon Landlord and its successors only with respect to breaches occurring during
its and their respective ownership of Landlord's interest hereunder.

                                   ARTICLE 3

                            LEASEHOLD IMPROVEMENTS

     Section 3.01. Leasehold Improvements from time to time designated by
Landlord as "Building Standard" are sometimes called in this Lease "Building
Standard Leasehold Improvements." Leasehold Improvements not designated as
Building Standard Leasehold Improvements are sometimes called in this Lease 
"Non-Building Standard Leasehold Improvements." Building Standard Leasehold
Improvements and Non-Building Standard Leasehold Improvements are collectively
called "Leasehold Improvements." If the Premises already contain Leasehold
Improvements from a prior occupancy, Tenant may, at its option, use such
improvements in connection with the construction of Leasehold Improvements in
the Premises, to the extent provided in the final plans and specifications for
the Leasehold Improvements approved by Landlord and Tenant. From and after the
Commencement Date, Tenant and Tenant's Contractor share be permitted to enter
the Premises and shall construct or cause to be constructed certain additional
Leasehold Improvements in accordance with the Tenant Space Plan and Working
Drawings prepared by Tenant subject to and in accordance with the terms and
provisions of the Work Letter executed simultaneously with this Lease, the form
of which Work Letter is attached hereto as Exhibit C. Landlord shall either
                                           ---------
approve or disapprove such Tenant Space Plan within seven (7) days after
Landlord's receipt thereof, which approval shall not be unreasonably withheld,
conditioned or delayed. Tenant and Tenant's Contractor may enter the Premises
for construction and demolition work and may occupy the Premises and conduct
business operations from the Premises, and regardless of such entry and
occupancy, Tenant shall not be required to pay Base Rent or Additional Rent
until the Rental Commencement Date. Subject to Section 5.02, the date on which
Tenant's Rent obligations shall be the date which is seventy (70) days after the
Commencement Date (the "Rental, Commencement Date"). If for any reason, Tenant
fails to complete construction of its additional Leasehold Improvements before
the Rental Commencement Date, then this Lease shall not be void or voidable, and
Tenant shall not be liable for any loss or damage resulting therefrom except
that Tenant's obligation to pay Base Rent and Additional Operating Expenses
shall commence as of the Rental Commencement Date, provided that Tenant shall
not be obligated to pay any Base Rent or Additional Operating Expenses for any
days (i.e. for the number of days) and the Rental Commencement Date shall be
postponed for the number of days that the completion of the construction is
delayed because of Events of Force Majeure (as defined in Section 27.06)
affecting Tenant or Tenant's Contractor or because of Landlord Delay (as defined

Improvement Space on or before December 14, 1992 or (ii) Tenant is not delivered
possession of the Basement Space on or before December 21, 1992, then Tenant
shall be entitled to terminate this Lease. However, without limiting the
foregoing right of Tenant, Landlord shall use reasonable efforts to deliver the
Premises to Tenant as soon as is practicable after the Commencement Date.

                               ACCEPTANCE OF THE
                       PREMISES AND BUILDING BY TENANT

       Section 4.01. Taking possession of the Premises by Tenant shall be
conclusive evidence that, except for any latent defects of which Tenant is not
aware after Tenant's exercise of a reasonable inspection period (but such
exception shall not include any latent defects in the work performed or
materials supplied by Tenant or Tenant's contractor) Tenant: (a) accepts the
Premises as suitable for the purposes for which they are leased; (b) accepts the
Building and every part and appurtenance thereof as being in good and
satisfactory condition; and (c) waives any claims against Landlord in respect of
defects in the Premises and its appurtenances, except for those defects not
discoverable by Tenant after conducting a reasonable inspection that are the
result of Landlord's negligence or willful misconduct.


                                   ARTICLE 5


                                     RENT


       Section 5.01. Base Rent; Additional Rent. Subject to any other applicable
provisions of this Lease, the Rent reserved by Landlord and payable by Tenant in
consideration of and under the terms of this Lease for each year of the Term
thereof (prorated on a daily basis for any period less than an entire year)
shall be and consist of:

              (a)    an annual base rent (sometimes herein called the "Base
Rent") in the amounts stated in Section 5.02 hereof, plus

              (b)    such other sums of money as shall become due and payable by
Tenant as Additional Rent (as hereinafter defined), which Additional Rent shall
be payable as hereinafter provided.

       Section 5.02. Base Rent. "Base Rent" shall, during the original Term
hereof, be at the per annum rate of $8.50 per square foot of Net Rentable Area
of Existing Space, $8.00 per square foot of Net Rentable Area of Improvement
Space, and $7.50 per square foot of Net Rentable Area of Basement Space. Tenant
covenants and agrees to pay Base

                                      -4-
<PAGE>
 
Rent in equal monthly installments of $56,091.21, in advance on the first day of
each and every calendar month during the Term of this Lease from and after the
Rental Commencement Date. Notwithstanding anything in this Lease to the
contrary, Tenant shall not be obligated to pay any Rent until the date that is
six (6) months after the Rental Commencement Date. The Base Rent payable during
any renewal period granted pursuant to Section 26.01 hereof shall be at the rate
therein provided. It is further understood that the rent for the seventh (7th)
full calendar month after the Rental Commencement Date has been paid in advance
upon the execution of this Lease and Landlord acknowledges receipt thereof.

       Section 5.03. Additional Rent. "Additional Rent" means all sums, other
than Base Rent, which Tenant is or becomes obligated to pay to Landlord under
this Lease, including, but not limited to, Additional Operating Expenses (as
hereinafter defined).

       Section 5.04. Additional Operating Expenses. "Additional Operating
Expenses" shall be computed separately for each square foot of Net Rentable Area
in the Premises for each calendar year or portion thereof which ensues after the
Commencement Date and prior to the end of the Term of this Lease and, for each
such calendar year or portion thereof, shall mean an amount (but not less than
zero) per square foot of Net Rentable Area in the Premises determined by
subtracting the amount described below in (b) from the amount described below in
(a), to wit:

       (a)   The arithmetic average of the Operating Expenses (as hereinafter
             defined) per square foot of Net Rentable Area in the Building
             incurred during such calendar year or portion thereof.

       (b)   The applicable Landlord's Expense Stop (as hereinafter defined) as
             to such square foot of Net Rentable Area in the Premises for such
             calendar year or portion thereof.

For all purposes under this Lease, the "arithmetic average" of the Operating
Expenses per square foot of Net Rentable Area in the Building for a calendar
year shall be determined by dividing the total amount of the Operating Expenses
incurred during such calendar year by the total number of square feet of Net
Rentable Area in the Building, and, likewise, the Operating Expenses for any
portion (less than all) of a calendar year for a square foot of Net Rentable
Area in the Building shall be determined by dividing the arithmetical average of
the Operating Expenses per square foot of Net Rentable Area in the Building for
such entire calendar year by the number of days in such year and by multiplying
the result obtained by the number of days in such portion of said calendar year.

as follows:


        (a)    For any full calendar year during the Term, "Landlord's Expense
Stop" shall mean $6.50.

        (b)    For any partial calendar year during the Term, "Landlord's
Expense Stop" means the product obtained by multiplying the amount in Section
5.05(a) by a fraction, the denominator of which is 365, and the numerator of
which is the number of days in such partial calendar year.

        Section 5.06. Operating Expenses.

        (a)    Subject to the provisions of subsection (b) hereof, "Operating
Expenses" as used herein means all expenses, costs, and disbursements of every
kind which Landlord shall be required to pay, in connection with the ownership,
operation, and maintenance of the Building and the Land, including, without
limitation, the following:

                      percent (3%) of the Base Rent and Additional Rent;
                      provided, however, that for the purpose of calculating the
                      Management Fee Allocation, Operating Expenses shall
                      exclude the Management Fee Allocation.


               (2)    Wages, salaries, and fees of all personnel at or below the

                      insurance, and benefits relating thereto; provided,
                      however, that if during the Term such personnel are also
                      working on other projects being periodically developed or
                      operated by Landlord, their wages, salaries, fees, and
                      related expenses shall be allocated by Landlord in good
                      faith among all of such projects, and only that portion of
                      such expenses allocable to the Building shall be included
                      as an Operating Expense.

               (3)    All supplies and materials directly used in the operation
                      and maintenance of the Building.

                      income attributable to the ownership and operation of the
                      Building and the cost of insurance against such perils and
                      occurrences as are commonly insured against by prudent

                      insurance premiums, surcharge, or ascribed cost thereof

                      Article 19 below as a result of any use by any tenant
                      (including Tenant) of such tenant's premises other than
                      for general office purposes shall not be a Operating
                      Expense, but shall instead be billed to and paid for by
                      such tenant separately and (B) if such insurance is
                      provided in the form of master insurance covering more
                      than the Building, then only an equitable portion of the
                      premiums therefor shall be included in Operating Expenses.

                      Section 14.02, the cost of insurance shall be Landlord's

                      attributable solely to tenants of the Building other than
                      Tenant).

              (8)     Amortization of the cost of capital investment items that
                      are installed primarily (and in good faith) to reduce
                      operating costs for the benefit of all the Building's

Year of the Term, an adjustment shall be made in computing the Operating
Expenses for that year so that those Operating Expenses that vary with occupancy

good faith judgment, would have been incurred had the total Net Rentable Area of
the Building been occupied during that year. All Operating Expenses shall be
computed according to generally accepted accounting principles, consistently
applied.

       Section 5.09. Failure to Pay; Interest. All past-due Rent shall bear
interest from and after the fifth (5th) day after it is due until paid at the
rate of interest per annum equal to the interest rate then being quoted by Bank
of America National Trust and Savings Association (or its successor) as its
"prime rate," plus two (2) points, or the maximum rate permitted under state or
federal law, if the aforesaid rate exceeds such maximum.

       Section 5.10. Additional Operating Expenses. As Additional Rent, Tenant
shall pay to Landlord an amount (if any) equal to the Additional Operating
Expenses for each square foot of Net Rentable Area included in the Premises
during any calendar year or portion thereof during the Term of this Lease;
provided that for any period of time which constitutes less than an entire
calendar year, the Additional Rent if any, payable by Tenant under this Section
5.10 for each square foot of Net Rentable Area in the Premises during such
portion of a calendar year shall be calculated on a proportionate per-day basis
as described in Sections 5.04 and 5.05 above. Notwithstanding the foregoing, if
the Consumer Price Index (as hereafter defined) on the first day of the calendar
month in which this Lease commences is less than the Consumer Price Index on the
first day of any calendar year during the original Term or any renewal Term
hereof, then Tenant shall not be obligated to pay Additional Operating Expenses
for each square foot of Net Rentable Area included in the Premises in any
calendar year in an amount greater than the product of (a) the Landlord's
Expense Stop multiplied by (b) a fraction the numerator of which is the Consumer
Price Index for the year for which the Additional Operating Expenses is being
computed and the denominator of which is the Consumer Price Index for the
calendar year 1992. Additionally, notwithstanding anything to the contrary
herein,

                                     -11-
<PAGE>
 
Tenant shall not be obligated to pay any Additional Operating Expenses for the
calendar year 1993. "Consumer Price Index" shall mean the Consumer Price Index
published by the Bureau of Labor Statistics, U.S. City Average, All Items for
Urban Wage Earners and Clerical Workers (1982-84=100).

       Section 5.11. Payment of Estimated Additional Rent in Respect of
Additional Operating Expenses. At least fifteen (15) days prior to the first day
of each calendar year during the Term of this Lease, Landlord shall notify 
Tenant of Landlord's good faith estimate of the amount, if any, of Additional
Rent which will become due by Tenant under Section 5.10 during the next calendar
year or part thereof. The amount of Additional Rent, if any, thus estimated by
Landlord to become due for any such period shall be divided into equal monthly
installments during such period (reduced proportionately for any partial month)
and shall be paid by Tenant in such equal monthly installments in advance on the
first day of each month during such period; provided that if Additional Rent is
estimated to accrue under Section 5.10 during a portion only of such period (as,
for example, a portion of a calendar year during which the Term hereof ends),
the entire amount of such estimated Additional Rent shall be payable in equal
monthly installments only during the portion of such period during which it is
estimated to accrue. If Landlord fails to give notice to Tenant of Landlord's
estimate of the amount of Additional Rent to become due by Tenant during any
period at least fifteen (15) days prior to commencement of such period as
required in the first sentence of this Section 5.11, Tenant shall not be
required to commence paying monthly installments of estimated Additional Rent 
for such period until the first day of the first calendar month which ensues at
least fifteen (15) days after notice of such estimate is given by Landlord to
Tenant, in which event the first monthly installment of estimated Additional
Rent to be paid by Tenant after receipt of such notice shall include all monthly
installments of estimated Additional Rent for such period which would have
become due through such installment payment date if Landlord had timely given
notice of estimated Additional Rent for such period as provided for in the first
sentence of this Section 5.11.

      Section 5.12. Correction of Estimated Payments. Within one hundred fifty
(150) days, or reasonably thereafter, after the end of each calendar year during
which any estimated Additional Rent has accrued under Section 5.11 above,
Landlord shall provide to Tenant a statement for such calendar year setting
forth, in reasonable detail, the Operating Expenses incurred during such
calendar year and the amount, if any, of Additional Rent due by Tenant under
Section 5.10 for such calendar year or any portion thereof. If the actual
Additional Rent, if any, due by Tenant under Section 5.10 for such calendar
year, or portion thereof, is greater than the estimated Additional Rent paid by
Tenant under Section 5.11 during such calendar year, or portion thereof, then
within thirty (30) days after receipt of such statement Tenant shall pay to
Landlord the amount of such excess. If the actual Additional Rent, if any, due
by Tenant under Section 5.10 for such calendar year, or portion thereof, is less
than the estimated Additional Rent paid by

                                     -12-
<PAGE>
 
Tenant under Section 5.11 during such calendar year, or portion thereof, then
Landlord shall allow a credit in the amount of such overpayment plus interest
thereon from the date of delivery of said statement from Landlord until the
credit is given, at the rate of interest per annum equal to the interest rate
being quoted by Bank of America National Trust and Savings Association (or its
successor) as its "prime rate" plus two (2) percent, or the maximum rate
permitted by state or federal law if the aforesaid rate exceeds such maximum,
against the aggregate payment of Base Rent and estimated Additional Rent
otherwise becoming due under Section 5.08(a) and Section 5.11 on the next
ensuing monthly payment of Rent due or dates, if any, after delivery of such
statement to Tenant; provided that if the Term of this Lease has ended or shall
end prior to utilization of such entire overpayment as a credit against Rent
hereunder, Landlord shall promptly refund such overpayment together with
applicable interest as provided pursuant to this Section 5.12 (to the extent not
credited against Rent otherwise becoming due hereunder) to Tenant.

       Section 5.13. Tenant's Right to Examine Records. Tenant shall have the
right at all reasonable times to audit and copy or reproduce at its own expense
Landlord's books and records relating to Additional Rent under this Lease for 
all or any part of the immediately preceding two (2) calendar years of the Term.
Landlord agrees that it will maintain complete and accurate records of all
costs, expenses and disbursements relating to Operating Expenses that shall be
paid or incurred by Landlord, its employees, agents or contractors, or any of
the foregoing. Landlord agrees to reimburse Tenant for the professional or
accounting costs or expenses incurred by Tenant in connection with any such
inspection or audit conducted by or for Tenant (including, without limitation,
the allocated cost of Tenant's internal accounting or auditing personnel, but in
no event shall such amounts exceed the amounts that would have been charged by
unaffiliated third parties of similar skill and competence and experience for
providing such services on a competitive basis), but only up to the amount of
$10,000 of such expenses, in the event said inspection or audit shall prove that
Operating Expenses or Additional Operating Expenses, or both, for the period of
time covered by such inspection or audit shall have been overstated by five
percent (5%) or more. Furthermore, Landlord agrees to adjust its computation of
Operating Expenses or Additional Operating Expenses, or both, to the extent that
inaccuracies or mistakes are discovered by Tenant or by other tenants of the
Building (to the extent such inaccuracies or mistakes detected are applicable to
Tenant pursuant to this Lease).

preference rights exercised by Tenant in the Building; and

       (l)  the services provided for in Sections 7.01 and 7.02 below.

                                   ARTICLE 7

                                   UTILITIES

       Section 7.01. While Tenant or a permitted sublessee or assignee is paying
Rent as required hereunder and has not abandoned the Premises, Landlord shall
furnish Tenant with the following services:

       (a)   hot and cold potable water at those points of supply provided
             periodically for normal lavatory use by tenants in the Building in
             such amounts and temperatures as may be customarily provided to
             tenants occupying

                                     -15-
<PAGE>
 
             comparable space in first-class office buildings in the suburban
             area of Houston, Texas; and

       (b)   heating, ventilating, and/or air conditioning in season during
             Normal Business Hours for the Building and at such temperatures and
             in such amounts as may customarily be provided to tenants occupying
             comparable space in first-class office buildings in the suburban
             area of Houston, Texas (such temperature ranges to be between 68'
             and 74' degrees fahrenheit).

        With respect to heating, ventilating, and/or air conditioning, if Tenant
requires air conditioning (heating and cooling) during any season outside the
hours and days specified above, Landlord shall furnish it only at Tenant's
request, and Tenant will bear the entire charge therefor.

       Section 7.02. While Tenant or a permitted sublessee or assignee is paying
Rent as required hereunder and has not abandoned the Premises, Landlord will
furnish sufficient power for lighting and for typewriters, voicewriters,
calculating machines, word processors, micro-computers, duplicating machines and
other machines of low electrical consumption, exclusive of electricity for (a)
special lighting which has electrical consumption in excess of Building Standard
lighting or (b) any item that consumes more than 0.5 kilowatts per square foot
of Net Rentable Area of the Premises per hour at rated capacity all of which
power shall be supplied by Landlord and paid for by Tenant as a part of the
Additional Rent.

       If Tenant's requirements for electricity exceed those described above,
Landlord, at Tenant's expense, will make reasonable efforts to supply such
service through the then-existing feeders servicing the Building and will bill
Tenant periodically for such additional service. Such additional consumption
shall be determined, at Landlord's election, either (i) by a survey performed by
a reputable consultant selected by Landlord and the reasonable cost of which is
to be paid for by Tenant, or, (ii) by a separate meter in the Premises to be
installed, maintained, and read by Landlord and the reasonable cost of
installation of such meter shall be paid for by Tenant.

       Except for the abatement of Rent as provided herein, Landlord will not be
liable in any way to Tenant for any failure or defect in the supply or character
of electric energy or any other utility service furnished to the Premises
because of any requirement, act, or omission of the public utility serving the
Building with electricity or any other utility service.

       All installations of electrical fixtures, appliances, and equipment
within the Premises will be subject to Landlord's prior written approval, such
approval not to be unreasonably withheld conditional, or delayed.

                                     -16-
<PAGE>
 
       Landlord's obligation to furnish electrical and other utility services as
described in this Article 7 will be subject to the rules and regulations of the
supplier of such electricity or other utility services and the rules and
regulations of any municipal or other governmental authority regulating the
business of providing electricity and other utility services.


       At all times Tenant's use of electrical current will never exceed the
capacity of existing feeders to the Building or the risers or wiring
installations; provided, however, that Landlord shall not reduce the capacity of
such existing feeders, risers and wiring installations to the Building and
Premises if such reduction would result in Tenant's not being able to use the
Premises for the uses permitted herein.

       Section 7.03. Failure to furnish, or any stoppage of, the services
provided for in Article 6 above and this Article 7 resulting from any cause
beyond Landlord's reasonable control will not make Landlord liable in any
respect for damages to either person, property, or business (other than the
abatement of Rent as provided herein), nor be construed as an eviction of Tenant
nor relieve Tenant of any of its obligations under this Lease, except as is
otherwise provided herein. Landlord shall use reasonable efforts to cause any
such services to be restored.

      Should stoppage of the services provided for in Article 6 above or this
Article 7 render the Premises untenantable (tenantability being presumed if
Tenant is using Premises in the usual manner for its intended purpose) for more
than three (3) consecutive days (or for more than five (5) days during any
calendar month) and be the result of the act or omission of Landlord, or its
employees, contractors or agents, then Tenant's rent shall abate during the
entire period of untenantability. Should stoppage of the services provided for
in Article 6 and this Article 7 render the Premises untenantable for more than
five (5) consecutive days (or for more than ten (10) days during any calendar
month) for any cause, Tenant's rent shall abate during the entire period of
untenantability. If the period of untenantability exceeds thirty (30)
consecutive days (or for more than forty-five (45) days in any sixty (60) day
period) for any cause, Tenant shall have the right to terminate the Lease after
the thirtieth consecutive day, or after forty-five (45) days of such
untenantability have elapsed in any sixty (60) day period, by giving written
notice to Landlord prior to full restoration of such services.

      Section 7.04. Landlord may require, at its option installation of a meter
or meters to monitor Tenant's use of electricity or the chilled water for
cooling purposes, the cost of installation of such meter or meters to be shared
equally by Landlord and Tenant.

                                      USE

       Section 8.01. The Premises shall be used only for general office purposes
and for no other purpose, with the only exception to the foregoing being those
light manufacturing activities described in Exhibit F to this Lease and the use
in connection therewith of those chemicals and in the quantities thereof
specified in Exhibit G to this Lease. Tenant agrees to use and maintain the
Premises in a clean, careful, safe, lawful, and proper manner consistent with
the foregoing.

       If a change in the use of the Premises by Tenant from that permitted
herein occurs (no implied consent of Landlord being hereby given therefor) and
such change results in a materially increased environmental risk to the
Premises or Building, then Landlord may (i) impose additional requirements upon
Tenant relating to the lessening of such additional environmental risk to the
Premises or Building or (ii) demand that Tenant cease such changed use giving
rise to the additional environmental risk to the Premises or Building.

                                   ARTICLE 9


           LAWS, ORDINANCES, AND REQUIREMENTS OF PUBLIC AUTHORITIES

       Section 9.01. Tenant shall, at its sole expense, comply with all laws,
orders, ordinances, and regulations of federal, state, county, and municipal
authorities, including the ADA, and with any directive of any public officer or
officers which shall, with respect to the use of the Premises or to any
abatement of nuisance, impose any violation, order or duty upon Landlord or
Tenant arising from Tenant's use of the Premises or from conditions which have
been created by or at the insistence of Tenant or required by reason of a breach
of any of Tenant's obligations hereunder.

       The foregoing obligations of Tenant under this Article 9 shall not apply
to any laws, orders, ordinances, regulations, or directives to which Landlord is
subject and which are applicable to the Building (but not the Premises), or
which generally relate to Landlord's leasing of space in the Building for
general office purposes. To the best of Landlord's knowledge, except as provided
below in Section 9.02, there are no Hazardous Substances used, stored, generated
or disposed of in the Building or the Land in violation of an applicable
environmental law, however, should there prove to be Hazardous Substances within
the Building or on the Land in violation of any environmental law, through no
fault of Tenant, Landlord shall except as otherwise provided below, promptly, at
its sole expense, take any and all necessary actions to cause the Building or
Land, or both, to be in compliance with all applicable environmental laws. As
used herein,

                                     -18-
<PAGE>
 
"Hazardous Substance" means any petroleum fuel, polychlorobiphenyls and any
hazardous or toxic substance, material or waste that is or becomes regulated by
any local government or authority, the State of Texas or the United States
Government, including, but not limited to, any material or substance defined as
a "hazardous waste", "extremely hazardous waste", "restricted hazardous waste",
"hazardous substances", "hazardous material" or "toxic pollutant" under the
Texas Statutes or under the Comprehensive Environmental Response, Compensation
and Liability Act, 42 U.S.C. (S)9601 et. seq.
                                     -------   

       If Tenant receives written notice of the violation of any law, order,
ordinance, or regulation, it shall promptly notify Landlord thereof.

       Section 9.02. (a) Landlord represents and warrants to Tenant that there
is no asbestos in the Building other than as set forth in that certain
Environmental Report dated October 16, 1989 prepared by Loflin Environmental
Services.

       (b) Landlord covenants that it has implemented, or if Landlord has not,
Landlord will promptly implement, at its sole cost and expense, an Operations
and Maintenance Plan ("Plan") during the duration of this Lease or until all
asbestos-containing materials ("ACM") are removed from the Property, whichever
comes first, to address the presence of all ACM on the Property. Such Plan shall
include (1) a regular program of inspections, to be conducted no less frequently
than annually, of all ACM known to be present on the Property to determine
whether ACM have deteriorated or otherwise become capable of releasing asbestos
fibers into the air; (2) a regular program of inspections to ensure that any
improvements or other activities of tenants of the Property have not and do not
disturb ACM; (3) documentation of all inspections; (4) the designation of a
representative of Landlord who will be responsible for all ACM-related
activities at the Property and who may be notified by Tenant in the event that
Tenant's proposed activities may result in the disturbance of ACM on the
Property; and (5) compliance with all applicable laws and regulations relating
to ACM.

      (c)    Landlord further covenants to notify Tenant promptly upon becoming
aware of any condition relating to ACM on the Property that may pose a threat to
the health of any of Tenant's employees, agents, or representatives.

      (d)    If (i) the representation and warranty contained in (a) above
proves to be incorrect and the presence of asbestos poses or may be reasonable
suspected of posing a threat to the health of Tenant's employees, agents, or
representatives, or (ii) if Landlord fails to perform any covenant contained in
(b) or (c) above, then Tenant may terminate this Lease upon thirty (30) days 
written notice to Landlord and thereupon Landlord shall reimburse Tenant for the
unamortized cost of Tenant's initial construction of Leasehold Improvements in
the same manner as if Landlord exercised its cancellation option pursuant to
Section 26.01.

                      OBSERVANCE OF RULES AND REGULATIONS

       Section 10.01.       Tenant and its servants, employees, agents,
visitors, and licensees shall observe faithfully and comply with the Rules and
Regulations attached hereto as Exhibit E; provided, however, in the event of a
                               ---------
conflict between the terms of this Lease and the Rules and Regulations (whether
now existing or hereafter created), then this Lease shall control.

       Landlord shall at all times have the right to make reasonable changes in
and additions to such Rules and Regulations, provided any changes in existing
rules or any new rules do not interfere with the lawful conduct of Tenant's
business in the Premises as permitted by this Lease and further provided that
such Rules and Regulations are applied uniformly to all tenants conducting
similar types of activities in the Building.

       Landlord shall have no responsibility or liability to Tenant and its
servants, employees, agents, visitors, and licensees with respect to any damages
or injuries to persons or property arising out of noncompliance with the Rules
and Regulations, or any of them, by any other tenant or person in the Building.

                                  ALTERATIONS


       Section 11.01.       Tenant shall not without Landlord's prior written
consent which consent shall not be unreasonably withheld, conditioned or
delayed, make any alterations to the Premises. Should Tenant desire to make any
such alterations, Tenant agrees to submit all plans and specifications for same
to Landlord for Landlord's written approval, which approval shall not be
unreasonably withheld, conditioned or delayed, before such work is begun.

       Upon Tenant's receipt of Landlord's written approval, and upon Tenant's
payment to Landlord of a Review Fee (as defined in this Section 11.01), if any,
as provided herein, Tenant may proceed with the construction of the approved
alterations, but only so long as the alterations are constructed in substantial
compliance with the approved plans and specifications and with the provisions
of this Article 11.

      All alterations shall be made at Tenant's expense, at Tenant's option,
either by Tenant's contractors which have been approved by Landlord, or by
Landlord's contractors on terms reasonably satisfactory to Tenant, including a
payment of the Review Fee, if any.

                                     -20-
<PAGE>
 
        All work in connection with such alterations shall:

        (a)    be performed in such a manner as to maintain harmonious labor
               relations;

        (b)    not alter the exterior appearance of the Building;

        (c)    not adversely affect the structure or safety of the Building;

        (d)    comply with all building, safety, fire, and other codes and
               governmental and insurance requirements;

        (e)    not result in any usage in excess of Building Standard of water,
               electricity, gas, heating, ventilating, or air-conditioning
               (either during or after such work) unless prior written
               arrangements satisfactory to Landlord are made with respect
               thereto; and

        (f)    be completed promptly and in a good and workmanlike manner.

        Tenant shall not obligated to pay to Landlord any fee or similar charge
for any alterations or additions to the Premises unless (i) such alterations or
additions affect the structural, mechanical, electrical or plumbing systems of
the Building and (ii) Landlord is incapable of reviewing and approving the plans
and specifications because Landlord does not have on its payroll any person or
persons qualified to review such plans and specifications (any such alteration
not satisfying (i) and (ii) above is herein called an "Exempt Alteration").
Tenant shall pay to Landlord, upon completion of any alteration or addition,
other than in connection with the initial Leasehold Improvements to the Premises
to be constructed and installed pursuant to the Tenant Space Plan (as such may
be amended in accordance with the Work Letter) a fee (the "Review Fee") equal to
all reasonable architectural and engineering fees and expenses paid by Landlord
in reviewing and approving the plans and specifications for any alteration that
is not an Exempt Alteration.

        Section 11.02.       All Leasehold Improvements, alterations, and
physical additions made or installed by or for Tenant in or to the Premises
other than Tenant's furniture, furnishings, personal property, equipment, and
removable trade fixtures shall be and remain Landlord's property, and shall not
be removed. Tenant agrees to remove, at Tenant's expense, all of its furniture,
furnishings, personal property, equipment, and removable trade fixtures by the
Expiration Date or the date of any earlier termination hereof, and shall
promptly repair all damage done to the Premises or the Building by such removal,
normal wear and tear excepted (or Tenant shall promptly reimburse Landlord for
the reasonable cost of repairing all damage done to the Premises or the Building
by

                                     -21-

such removal, normal wear and tear excepted). Notwithstanding the foregoing,
Tenant shall be entitled to remove the freight elevator at the expiration or
earlier termination of this Lease provided Tenant promptly repairs all damage
done to the Premises or the Building by such removal, normal wear and tear
excepted (or provided that Tenant promptly reimburses Landlord for the
reasonable cost of repairing an damage done to the Premises or the Building by
such removal, normal wear and tear excepted). If Tenant elects not to remove the
freight elevator, Tenant shall so notify Landlord in writing and Landlord may
request in writing that Tenant remove the freight elevator and thereupon Tenant
shall remove the freight elevator at Tenant's sole cost and expense and Tenant
shall promptly repair all damage done to the Premises or the Building by such
removal, normal wear and tear excepted (or Tenant shall promptly reimburse
Landlord for the reasonable cost of repairing all damage done to the Premises or
the Building by such removal, normal wear and tear excepted).

                                     LIENS

      Section 12.01.        Tenant shall keep the Premises free from any liens
arising from any work performed, materials furnished or obligations incurred by
or at the request of the Tenant. All persons either contracting with Tenant or
furnishing or rendering labor and materials to Tenant shall be notified in
writing by Tenant that they must look only to Tenant for payment for any labor
and materials. Nothing contained in this Lease shall be construed as Landlord's
consent to any contractor, subcontractor, laborer, or materialman for the
performance of any labor or the furnishing of any materials for any specific
improvement, alteration, or repair of, or to, the Premises, nor as giving Tenant
any right to contract for, or permit the performance of, any services or the
furnishing of any materials that would result in any liens against the Premises.

      If any lien is filed against the Premises or Tenant's leasehold interest
therein, Tenant shall discharge same within ten (10) days after Tenant learns
that the lien has been filed. If Tenant fails to discharge any lien within such
period, then, in addition to any other right or remedy of Landlord, Landlord
may, at its election, discharge the lien by either paying the amount claimed to
be due or obtaining the discharge by deposit with a court or a title company or
by bonding. Tenant shall pay on demand any amount paid by Landlord for the
discharge or satisfaction of any lien, and all reasonable attorneys' fees and
other legal expenses of Landlord incurred in defending any such action or in
obtaining the discharge of such lein, together with all necessary disbursements
in connection therewith.

      Notwithstanding the foregoing, Tenant may contest the amount or validity
of any such lien, provided that Tenant first posts with Landlord an indemnity
bond issued by a

                                     -22-
<PAGE>
 
corporate surety reasonably satisfactory to Landlord in an amount required by
law. This bond shall name Landlord and such other parties as Landlord may direct
as assignees thereunder.

                               ORDINARY REPAIRS

       Section 13.01.        Tenant shall, at all times during the Term hereof
and at Tenant's sole cost and expense, keep the Premises and every part thereof
(but excluding exterior glass or any structural elements, which Landlord shall
be obligated to repair) in good condition and repair.

       Tenant shall, at the end of the Term hereof, surrender to Landlord the
Premises and all alterations, additions, and improvements thereto in the same
condition as when received, ordinary wear and tear and damage by fire or other
casualty not required hereunder to be repaired by Tenant excepted.

       If Tenant fails to make such repairs promptly, Landlord may, at its
option, make the repairs, and Tenant shall pay Landlord on demand Landlord's
actual costs in making such repairs, plus the Review Fee, if any, as provided in
Section 11.01.

       Landlord has no obligation and has made no promise to alter, remodel,
improve, repair, decorate, or paint the Premises, or any part thereof, except as
specifically herein set forth. No representations respecting the condition of
the Premises or the Building have been made by Landlord to Tenant except as
specifically herein set forth.

                                   INSURANCE

       Section 14.01.       Tenant shall, during the Term and at its sole
expense, obtain and keep in force, with Tenant, Landlord, and the mortgagees of
Landlord named as insured therein (except with respect to the Workers'
Compensation coverage) as their respective interests may appear, the following
insurance:

       (a)    Fire insurance, including extended coverage, vandalism, and
              malicious mischief, upon property of every description and kind
              owned by Tenant and located in the Building or for which Tenant is
              legally liable or installed by, or on behalf of, Tenant including,
              without limitation, furniture, fittings, installations, fixtures,
              and any other personal property, Non-Building

                                     -23-
<PAGE>
 
               Standard Leasehold Improvements and alterations, in an amount not
               less than ninety percent (90%) of the full replacement cost
               thereof;

        (b)    Comprehensive General Liability Insurance Coverage, to include
               personal injury, bodily injury, broad form property damage,
               operations hazard, owner's protective coverage, contractual
               liability, and products and completed operations liability, in
               limits not less than $1,000,000, inclusive.

        (c)    Workers' Compensation and Employer's Liability insurance, in such
               form and amounts as are required by applicable law.

        (d)    Any other form or forms of insurance as Tenant or Landlord or the
               mortgagees of Landlord may reasonably require from time to time
               in form, in amounts, and for insurance risks against which a
               prudent tenant of a comparable size and in a comparable business
               would protect itself; provided, however, that as long as Landlord
               is Chevron U.S.A. Inc. or a related entity, the provisions of
               this Section 14.01(d) shall not apply.

All policies shall be taken out with insurers that are licensed in Texas and
have a Best's Rating of B+ or better in form reasonably satisfactory from time
to time to Landlord. Tenant agrees that certificates of insurance reasonably
acceptable to Landlord will be delivered to Landlord or the mortgagees of
Landlord as soon as practicable after the placing of the required insurance, but
not later than ten (10) days after Tenant takes possession of all or any part of
the Premises. All policies shall contain an undertaking by the insurers to
notify Landlord and the mortgagees of Landlord in writing not less than fifteen
(15) days before any material change, reduction in coverage, cancellation, or
other termination thereof. The insurance policies (if more than one) required in
(b) above shall name Landlord as an additional insured.


       Section 14.02.        During the Term, Landlord shall insure the Building
and the Building Standard Leasehold Improvements (excluding any property which
Tenant is obligated to insure under Section 14.01 thereof) against damage by
fire and standard extended coverage perils (including vandalism and malicious
mischief coverage) in amounts equal to one hundred percent (100%) of the
insurable value thereof (actual replacement value without deduction for physical
depreciation) and comprehensive general public liability and broad form property
damage insurance in such amounts as shall be appropriate for a first-class
office building project in the suburban area of Houston, Texas, but in no event
with limits less than a combined single limit of $1,000,000, with overlying
umbrella coverage (or a combination of primary and umbrella coverage) to a limit
of $5,000,000. Landlord shall also maintain employee's liability insurance with
a minimum limit of $1,000,000 for bodily injury; provided, however, that
Landlord shall have the right at its election, to maintain all such insurance
under a program of self-assumption of risk

                                     -24-
<PAGE>
 
in lieu of purchasing an insurance policy or policies pursuant to Chevron's 
Self-Adjusted Claims Program if it is Landlord's normal policy to self-assume
against such perils for its property. Landlord may, but shall not be obligated
to, take out and carry any other form or forms of insurance as it or Landlord's
mortgagees may reasonably determine advisable. Notwithstanding any contribution
by Tenant to the cost of insurance premiums, as provided herein, Tenant
acknowledges that such contribution in and of itself, shall not confer upon
Tenant the right to receive any proceeds from any such insurance policies
carried by Landlord for which such contribution by Tenant has been made, unless
said insurance covers any of Tenant's property required to be insured by Tenant
hereunder. Landlord will not have to carry insurance of any kind on any Non-
Building Standard Leasehold Improvements, on Tenant's furniture or furnishings,
or on any of Tenant's fixtures, equipment, improvements, or appurtenances under
this Lease; and Landlord shall not be obligated to repair any damage thereto or
replace the same.

      Section 14.03.       Landlord represents and warrants to Tenant that
Tenant's use of the Premises in accordance with Section 8.01 hereof will not
violate any insurance policy carried by Landlord. With respect to those
materials or substances set forth in Exhibit G, which are used by Tenant in
connection with Tenant's use of the Premises as permitted herein, Tenant shall
at all times comply with all applicable law regarding the storage and handling
of such materials or substances. Tenant shall not bring or keep or permit to be
brought to the Premises or kept therein, anything (or any quantity of such item)
not set forth on Exhibit G attached hereto that is prohibited by any insurance
policy carried by Landlord or Tenant periodically in force covering the
Building, the Leasehold Improvements, or the Premises. If Tenant's use of the
Premises does not comply with Section 8.01 hereof, and if such non-permitted use
is prohibited by any insurance policy carried by Landlord and such violation
could lead to a cancellation or reduction in the coverage afforded by such
policy, Tenant shall cease such non-permitted use giving rise to any such
cancellation or reduction, or threatened cancellation or reduction of coverage,
immediately after notice thereof and the failure of Tenant to do so shall
constitute an event of default hereunder, and Landlord may do any one or more of
the following without any notice or demand:

      (a)    Exercise any one or more of the remedies provided in Section 23.02
             hereof;

      (b)    Enter upon the Premises and attempt to remedy such condition, in
             which event Landlord shall not be liable for any damage or injury
             caused to any property of Tenant or of others located on the
             Premises resulting from such entry and Tenant shall promptly pay to
             Landlord as Additional Rent the cost to Landlord of remedying or
             attempting to remedy such condition.

In the case of an increase or threatened increase in insurance premiums in
connection with any use by Tenant of the Premises not permitted herein (no
implied consent of

                                     -25-
<PAGE>
 
Landlord hereby given to any such use), Tenant shall pay any actual increase in
premiums as Additional Rent within ten (10) days after being billed therefor by
Landlord. In determining whether increased premiums are a result of Tenant's use
of the Premises, a schedule issued by the organization computing the insurance
rate on the Building or the Leasehold Improvements showing the various
components of such rate shall be conclusive evidence of the several items and
charges which make up such rate. Provided Tenant's use of the Premises as herein
permitted is not materially impaired, Tenant shall promptly comply with all
reasonable requirements of the insurance authority or any present or future
insurer relating to the Premises.

       Section 14.04.       All policies of fire, extended coverage or similar
casualty insurance, which either party obtains for the Premises or the Building,
as applicable, shall include a clause or endorsement denying the insurer any
rights of subrogation against the other party to the extent rights have been
waived by the insured before the occurrence of injury or loss. Anything in this
Lease to the contrary notwithstanding, Landlord and Tenant each hereby waives
any and all rights of recovery, claim, action, or cause of action, against the
other and such party's agents, servants, partners, shareholders, officers, or
employees for injury or loss or damage that may occur to the Premises, the
Building or the Land, or any improvements thereto or thereon, or any property of
such party therein or thereon, by reason of fire, the elements, or any other
cause which is or is required to be insured against (whether by assumption of
the risk as permitted herein or policies of insurance obtained by insurance
carriers) under the terms of the fire and extended coverage insurance policies
referred to in this Article 14, regardless of the amount of proceeds payable
under the insurance policies (or whether such loss was assumed as permitted
herein by Landlord) and regardless of cause or origin, including the negligence
or other acts or omissions of the other party hereto, its agents, officers,
partners, shareholders, servants, or employees.

                                  ARTICLE 15


                         DAMAGE BY FIRE OR OTHER CAUSE

      Section 15.01.       Subject to Sections 15.02, 15.03, and 15.04 hereof,
if the Premises or the Building Standard Leasehold Improvements are damaged by
fire or other casualty against which Landlord is required to maintain a policy
of insurance under Section 14.02 or elects to assume the risk therefor as
permitted therein, Landlord shall, to the extent of the original Building
Standard Leasehold Improvements, diligently attempt to have the damage repaired
with reasonable speed at the expense of Landlord, subject to delays that may
arise by reason of adjustment of loss under insurance policies and for other
delays beyond Landlord's reasonable control.

                                     -26-
<PAGE>
 
       Section 15.02.       Notwithstanding anything to the contrary in this
Lease, if the Premises are damaged or destroyed by any cause whatsoever, and if,
in Landlord's reasonable opinion, (a) the Premises cannot be rebuilt or made fit
for Tenant's purposes within ninety (90) days of the damage or destruction (or
the Premises are not actually rebuilt or made fit again for Tenant's purposes
within one hundred twenty (120) days after the date of such damage or
destruction), or (b) the proceeds from insurance remaining after payment of any
such proceeds to Landlord's mortgagee are insufficient to repair or restore the
damage or destruction, then Landlord or Tenant may, at its option, terminate
this Lease by giving the other party notice of termination within sixty (60)
days after such damage or destruction, and thereupon, Rent and any other
payments for which Tenant is liable under this Lease shall be apportioned and
paid to the date of such damage, and Tenant shall as soon as reasonably
possible, but in no event longer than within sixty (60) days vacate the Premises
to Landlord, provided, however, that those provisions of this Lease which are
designated to cover matters of termination and the period thereafter shall
survive the termination hereof.

       Section 15.03.       If the Building is damaged or destroyed by any cause
whatsoever (a) not required to be covered by insurance (or the risk therefor is
elected by Landlord to be assumed as permitted herein against) hereunder and the
cost to repair such damage or destruction according to Landlord's reasonable
estimate will exceed $1,000,000, or (b) the cost of which to repair according to
Landlord's reasonable estimate exceeds $1,000,000 and which damage or
destruction is covered by insurance required hereunder but the proceeds are not
available for the repair of restoration of the Building through no fault of
Landlord or (c) and in Landlord's reasonable estimate after conferring with
Landlord's general contractor and insurance advisor, the damage or destruction
to the Building cannot or will not be repaired or restored by Landlord using
reasonable diligence within one hundred eighty (180) days after such damage or
destruction (or the Building is not actually rebuilt or made fit again within
two hundred ten (210) days after the date of such damage or destruction), then
in the event of either (a), (b), or (c) above, Landlord may, and in the event of
(c) above, Tenant may, at its option, terminate this Lease by giving the other
party written notice of termination within sixty (60) days after such damage,
and thereafter Tenant shall vacate the Premises sixty (60) days after delivery
of notice of termination, and thereupon, Rent and any other payments shall be
apportioned and paid to the date on which possession is relinquished, if Tenant
continues to occupy the Premises for said sixty (60) day period.

      Section 15.04.       If the Building, the Premises, or Building Standard
Leasehold Improvements are substantially damaged by fire or other cause at any
time during the last ten (10) months of the then current Term and Tenant has not
elected to exercise a renewal option, or if such damage occurs at any time
during the last two (2) years of the last renewal Term, then Landlord or Tenant
may terminate this Lease upon written notice to the other party given within
sixty (60) days of the date of such damage, and upon such

                                     -27-
<PAGE>
 
termination Tenant shall vacate the Premises sixty (60) days after delivery of
notice of termination, and thereupon Rent and any other payments shall be
apportioned and paid to the date on which possession is relinquished, if Tenant
continues to occupy the Premises for said sixty (60) day period, and Tenant
shall immediately vacate the Premises according to such notice of termination.

       Section  15.05.      Except for Tenant's right to abate rent as provided
in Sections 7.03 and 23.05 of this Lease, no damages, compensation, or claim
shall be payable by Landlord for inconvenience, loss of business, loss of
profits, or annoyance arising from any repair or restoration of any portion of
the Premises, the Building Standard Leasehold Improvements, or the Building.
Landlord shall use reasonable efforts to have such repairs made promptly so as
not unnecessarily to interfere with Tenant's occupancy.

       Section  15.06.      The provisions of this Article shall be considered
an express agreement governing any case of damage or destruction of the
Building, the Building Standard Leasehold Improvements, the Non-Building
Standard Leasehold Improvements, or the Premises by fire or other casualty.

       Section  15.07.      Tenant shall promptly notify Landlord if the
Premises or the Building Standard Leasehold Improvements are damaged by any
cause whatsoever. If the Building, Premises, or Building Standard Leasehold
Improvements shall be damaged by fire or other casualty so as to render any
portion of the Premises untenantable (i) through no neglect of Tenant, its
agents, employees or invitees or (ii) through the neglect of Tenant, its agents,
employees or invitees at a time when Landlord is carrying rent loss insurance,
then the Base Rent and Additional Operating Expenses hereunder shall abate as to
that portion of the Premises rendered untenantable by such damage from the date
of such casualty until such time as Landlord reasonably determines that such
damaged portion of the Premises has been made tenantable.

                                  ARTICLE 16


                                 CONDEMNATION

       Section  16.01.      If a material part of the Premises or the Building
shall be taken or condemned for any public purpose, whether such taking or
condemnation shall be temporary or permanent, Landlord or Tenant, may terminate
this Lease. If all of the Premises shall be taken or condemned for any public
purpose, this Lease shall automatically terminate. All proceeds from any taking
or condemnation shall belong to and be paid to Landlord; provided, however, that
any awards specifically identified and made payable to Tenant (i) for the taking
of personal property and fixtures belonging to and removable by Tenant hereunder
or (ii) for the interruption of, damage to, or

                                     -28-
<PAGE>
 
relocation of Tenant's business or (iii) the unamortized value of any
improvements, alterations or additions paid for by Tenant, shall be payable to
Tenant. Additionally, nothing contained herein shall preclude Tenant from
pursuing any claim in its own behalf in connection with any such taking or
condemnation.

                                  ARTICLE 17


                           ASSIGNMENT AND SUBLETTING

      Section 17.01.       Except as provided in Section 17.02, if Tenant should
desire to assign this Lease or sublet the Premises (or any part thereof), Tenant
shall give Landlord written notice at least thirty (30) days in advance of the
date on which Tenant desires to make such assignment or sublease. Landlord
shall then have a period of thirty (30) days following receipt of such notice
within which to notify Tenant in writing that Landlord elects either:

      (a)    to permit Tenant to assign or sublet such space, provided that if
             the rental rate (prorated to reflect the Base Rate allocable to
             that portion of the Premises subject to such assignment or sublease
             agreed upon between Tenant and its proposed assignee or subtenant
             is greater than the Base Rate that Tenant must pay Landlord
             hereunder, then such excess shall constitute "Excess Rent" for
             purposes hereof and fifty percent (50%) of such Excess Rent shall
             be payable by Tenant to Landlord as provided herein; provided,
             however, that prior to being required to pay such portion of Excess
             Rent to Landlord, Tenant shall deduct from the Excess Rent first
             becoming due and payable under such assignment or sublease and
             shall be entitled to retain its Reimbursable Expenses. For purposes
             hereof, "Reimbursable Expenses" shall mean and refer to Tenant's
             reasonable out-of-pocket expenses associated with such assignment
             or sublease including reasonable brokerage commissions and
             attorney's fees and other costs relating to permitted alterations
             or improvements to the Premises to accommodate such assignment or
             subletting. Upon request at any time, and from time to time, Tenant
             shall be obligated to provide Landlord an accounting of such
             Reimbursable Expenses incurred by Tenant and copies of invoices
             relating thereto. Such Excess Rent minus the Reimbursable Expense
             shall be considered Additional Rent owed by Tenant to Landlord, and
             shall be paid by Tenant to Landlord in the same manner that Tenant
             pays Base Rent; or

      (b)    to refuse to consent to Tenant's assignment or subleasing of such
             space and to continue this Lease in full force and effect as to the
             entire Premises; provided, however, that Landlord will not
             unreasonably withhold, delay or condition its approval or consent
             of any assignment or subletting.

                                     -29-
<PAGE>
 
If Landlord shall fail to notify Tenant in writing of such election within such
thirty (30) day period, Landlord shall be deemed to have elected option (b)
above. No assignment or subletting by Tenant, even if done by Tenant without
Landlord's consent pursuant to Section 17.02, shall relieve Tenant of Tenant's
obligations under this Lease. Any attempted assignment or sublease by Tenant in
violation of the terms and provisions of this Article 17 shall be void.

       Section 17.02.       Landlord may sell, transfer, assign, or convey, all
or any part of the Building and any and all of its rights under this Lease, and
in the event Landlord assigns its rights under this Lease, Landlord shall be
released from any obligations hereunder attributable to periods of time after
such assignment, and Tenant agrees to look solely to Landlord's successor in
interest for performance of such obligations.

                                  ARTICLE 18


                                INDEMNIFICATION


      Section 18.01.        Subject to the terms of Sections 4.01 and 14.04 of
this Lease, Tenant waives all claims against Landlord and its agents, employees,
and representatives (herein collectively referred to as "Landlord") arising out
of damage to any property or injury to, or death of, any person in, upon or
about the Premises demised hereby to Tenant arising at any time and from any
cause (other than the sole negligence [but including the contributory
negligence], gross negligence and willful misconduct of Landlord, its agents,
employees, representatives or contractors), including, without limitation, the
negligence of other tenants of the Building, or their agents, employees,
representatives, or contractors, and Tenant shall hold Landlord harmless from
all liabilities, claims, losses, damages and expenses, including environmental
remediation or clean-up charges, arising from any damage, injury or death
resulting from any breach or default on the part of Tenant in the performance of
any covenant or agreement of Tenant to be performed under this Lease, or from
any act or neglect of Tenant, its employees, agents or contractors, and shall
defend Landlord against any claim or suit arising therefrom. Landlord waives all
claims against Tenant arising out of damage to any property or injury to, or
death of, any person in, upon or about that portion of the Building other than
the Premises, arising at any time and from any cause (other than the negligence,
gross negligence or willful misconduct of Tenant, its agents, employees,
representatives, contractors), and Landlord shall hold Tenant harmless from all
liabilities, claims, losses, damages and expenses, including environmental
remediation or clean-up charges in respect of any damage, injury or death
resulting from any breach or default on the part of Landlord in the performance
of any covenant or agreement of Landlord to be performed in this Lease, or from
any act or neglect of Landlord, its employees, agents or contractors, and shall
defend Tenant against any claim or suit arising therefrom. Each party's

                                     -30-
<PAGE>
 
foregoing indemnity obligation shall include reasonable attorneys' fees,
investigation costs, and all other reasonable costs and expenses incurred by the
indemnified party from the first notice that any claim or demand has been made
or may be made, and shall not be limited in any way by any limitation on the
amount or type of damages, compensation or benefits payable under applicable
workers' compensation acts, disability benefit acts, or other employee benefit
acts. The provisions of this Article 18 shall survive the termination of this
Lease with respect to any damage, injury or death occurring before such
termination.


                                  ARTICLE 19


                           SURRENDER OF THE PREMISES


       Section 19.01.       Upon the expiration or other termination of this
Lease for any cause whatsoever, Tenant shall peacefully vacate the Premises in
as good order and condition as the same were at the beginning of the Term or as
may thereafter have been improved by Landlord or Tenant reasonable use and wear
thereof and damage from fire or casualty insured or required to be insured by
Landlord hereunder and damage by any other casualty not required to be repaired
by Tenant hereunder excepted. Should Tenant continue to hold the Premises after
the termination of this Lease, whether the termination occurs by lapse of time
or otherwise, such holding over shall, unless otherwise agreed to by Landlord in
writing, constitute and be construed as a tenancy at will at a daily Base Rent
equal to one-thirtieth (1/30th) of an amount equal to one and one-half (1-1/2)
times the monthly Base Rent hereunder, plus all Additional Rent that would have
been due hereunder for the period involved if such period had been included in
the Term, and subject to all of the other terms set forth herein except any
right to renew this Lease. Tenant shall be liable to Landlord for all damage
that Landlord suffers because of any wrongful holding over by Tenant for a
period of more than seven (7) days after the expiration of the Term of this
Lease, and Tenant shall indemnify Landlord against (i) all claims made by any
other tenant or prospective tenant against Landlord resulting from delay by
Landlord in delivering possession of the Premises to such other tenant or

                             ESTOPPEL CERTIFICATES

      Section 20.01.       Tenant agrees to furnish periodically, when requested
by Landlord or the holder of any deed of trust or mortgage covering the

business days of Tenant's receipt of such written request, a certificate signed
by Tenant certifying (i) that this Lease is in full

                                     -31-

force and effect and unmodified (or if there have been modifications, that the
same is in full force and effect as modified and stating the modifications, if
any); (ii) that the Term of this Lease has commenced and the full Rent is then
accruing hereunder; (in) that Tenant has accepted possession of the Premises and
that except as stated in the certificate, to Tenant's knowledge, any
improvements required by the terms of this Lease to be made by Landlord have
been completed to the satisfaction of Tenant; (iv) that except as stated in the
certificate, no Rent under this Lease has been paid more than thirty (30) days
in advance of its due date; (v) that the address for notices to be sent to
Tenant is as set forth in this Lease (or has been changed by notice duly given
and is as set forth in the certificate); (vi) that except as stated in the
certificate, Tenant, to Tenant's knowledge as of the date of such certificate,
has no charge, lien, or claim of offset under this Lease or otherwise against

stated in the certificate, to the knowledge of Tenant, Landlord is not then in
default under this Lease; and (viii) such other matters as may reasonably be

Landlord shall deliver within twenty (20) days of Landlord's receipt of such
written request, in reasonable form, an estoppel certificate to Tenant and any
party designated by Tenant certifying (if such be the case) that this Lease is
in full force and effect, the date of Tenant's most recent payment of Rent, and
to Landlord's knowledge, that Tenant is not in default under this Lease, or
stating in reasonable detail, the nature of such then continuing default and any

                                 SUBORDINATION


       Section 21.01.        This Lease is subject and subordinate to any deeds
of trust, mortgages, or, other security instruments which presently or may in
the future cover the Building and the Land, or any interest of Landlord therein,
and to any advances made on the security thereof, and to any increases,
renewals, modifications, consolidations, replacements, and extensions of any of
such deeds of trust, mortgages, or security instruments. Provided, however, that
any such contractual subordination by Tenant shall not become effective until
such deed of trust holder or mortgagee shall enter into a non-disturbance and
attornment agreement with Tenant (or Tenant's successors or assigns) agreeing
that notwithstanding such subordination, so long as no event of default is
occurring under this Lease, neither this Lease nor any of the rights of Tenant
hereunder shall be disturbed, terminated or subject to termination by any
trustee's sale, any action to enforce the security therefor or by any proceeding
or action in foreclosure. Contemporaneously with the execution of this Lease,
Landlord shall provide Tenant with

                                     -32-
<PAGE>
 
a non-disturbance agreement providing the terms set forth in the preceding
sentence and in a form reasonably acceptable to Tenant, executed by (i) any
ground lessor or ground lessee holding an interest in the Premises, the
Building, or the Land, or any part thereof superior to Landlord or Tenant and
(ii) Landlord's lender and any other holder of a mortgage or deed of trust
presently encumbering the Premises, the Building or the Land or any part 
thereof, provided that if no such non-disturbance agreements are provided to
Tenant the non-delivery of such instruments to Tenant shall constitute a
representation and warranty by Landlord to Tenant that no such lease, mortgage
or other encumbrance exists. Any subordination effected in accordance with this
Section 21.01 is declared by Landlord and Tenant to be self-operative and no
further instruments shall be required to effect such subordination of this
Lease. Tenant shall, however, upon demand execute, acknowledge and deliver to
Landlord any further instruments and certificates evidencing such subordination
as Landlord may reasonably require, provided Tenant is supplied the non-
disturbance and attornment agreement as required herein. This Lease is further
subject and subordinate to all applicable ordinances of the City of Houston or
relevant governmental authority; provided, however, if any such present or
future ordinance would serve to materially impair Tenant's use of the Premises
as permitted herein, then Tenant shall be entitled to terminate this Lease upon
sixty (60) days written notice to Landlord.

      Section 21.02.       At any time, before or after the institution of any
proceedings for the foreclosure of any such deeds of trust, mortgages, or other
security instruments, or the sale of the Building under any such deeds of trust,
mortgages, or other security instruments, provided Tenant has been supplied the
non-disturbance and attornment agreement referred to in Section 21.01, then
Tenant shall attorn to such Purchaser upon any sale or the grantee under any 
deed in lieu of such foreclosure and recognize such purchaser or grantee as
Landlord under this Lease. The agreement of Tenant to attorn contained in the
preceding sentence shall survive any such foreclosure sale, trustee's sale, or
conveyance in lieu thereof.

facilities ("Parking Facilities") in common with other tenants in the Building
during the Term to the extent, if any, so provided in Exhibit D hereto.

                             DEFAULT AND REMEDIES


      Section 23.01.       The occurrence of any one or more of the following
events shall constitute an "event of default" by Tenant under this Lease:

      (a)    if Tenant shall fail to pay any Rent or other sums payable by 
Tenant hereunder as and when such Rent or other sums become due and payable and
such failure continues for ten (10) days after written notice thereof from
Landlord;

      (b)    if Tenant shall fail to perform or observe any other term hereof
(other than the provisions of Section 14.03) or any of the Rules and Regulations
and such failure shall continue for more than fifteen (15) days after notice 
thereof from Landlord or for such longer period as reasonably necessary so long
as Tenant shall continuously and diligently pursue the remedy of such default at
all times until such default is cured, but in no event more than ninety (90)
days after Tenant is provided notice of such failure.

      (c)    if any petition is filed by or against Tenant under any section or
chapter of the present or any future federal Bankruptcy Code or under any
similar law or statute of the United States or any state thereof (and with
respect to any petition filed against Tenant, such petition is not dismissed
within ninety (90) days after the filing thereof, or Tenant shall be adjudged
bankrupt or insolvent in proceedings filed under any section or chapter of the
present or any future federal Bankruptcy Code or under any similar law or
statute of the United States or any state thereof;

      (d)    if Tenant becomes insolvent;

      (e)    if a receiver, custodian, or trustee is appointed for Tenant or for
any of the assets of Tenant which appointment is not vacated within ninety
(90) days of the date of such appointment; or

      (f)    any events that constitute an event of default under the terms of
Section 14.03 hereof.

      Section 23.02.       If an event of default occurs and at any time
thereafter while Tenant remains in default, Landlord may do any one or more of
the following without notice or demand, provided however, that Landlord shall
comply with the applicable provisions of the Texas Property Code, as amended 
from time to time:

                                     -34-
<PAGE>
 
      (a)    Terminate this Lease, and consider Tenant's event of default as an
anticipatory repudiation of this Lease and Tenant immediately shall become
liable for damages equal to the total of:

             (1)    the costs of recovering the Premises;

             (2)    the unpaid Rent earned as of the date of termination, plus
                    interest thereon at a rate per annum from the due date equal
                    to the lesser of (a) the prime rate plus two percent (2%) or
                    (b) the maximum rate of interest allowed by state or federal
                    law;

             (3)    the amount of the excess of (i) the total Rent and other
                    benefits which Landlord would have received under the Lease
                    for the remainder of the then current Term without regard to
                    any renewals thereof, at the rates then in effect, over (ii)
                    the fair market rental value of the balance of the then
                    current Term as of the time of such termination, each item
                    discounted at the rate of eight percent (8%) per annum to
                    the then present value; and

             (4)    all other sums of money and damages owing hereunder by
                    Tenant to Landlord;

      (b)    Enter upon and take possession of the Premises as Tenant's agent
without terminating this Lease and without being liable to prosecution or any
claim for damages therefor, and Landlord may relet the Premises as Tenant's
agent and receive the Rent therefor. Landlord shall use reasonable efforts to
relet the Premises; provided, however, that Landlord's failure to relet the
Premises shall not release or affect Tenant's liability for Rent or damages and
provided further that Landlord shall have the right to give preference to
leasing other premises in the Building over the reletting of the Premises. Any
rental received by Landlord from reletting the Premises as Tenant's agent shall
be applied first against the reasonable cost of renovating, repairing and
altering the Premises for such new tenant, and then against any sums due under
this Lease. Tenant shall pay to Landlord on demand any deficiency between the
sums due hereunder and that portion of any rental received from reletting
applied against such sums.

      (c)    Do whatever Tenant is obligated to do under this Lease and enter
the Premises without being liable to prosecution or any claim for damages
therefor, to accomplish this purpose. Tenant shall reimburse Landlord within ten
(10) days for any expenses which Landlord incurs in thus effecting compliance
with this Lease on Tenant's behalf, and Landlord shall not be liable for any
damages suffered by Tenant from such action.

                                     -35-
<PAGE>
 
      Section 23.03.       No act or thing, done by Landlord or its agents
during the Term shall constitute an acceptance of an attempted surrender of the
Premises, and no agreement to accept a surrender of the Premises shall be valid
unless made in writing and signed by Landlord. No reentry or taking possession
of the Premises by Landlord shall constitute an election by Landlord to
terminate this Lease, unless a written notice of such intention is given to
Tenant. Notwithstanding any such reletting, reentry or taking possession,
Landlord may at any time thereafter terminate this Lease for a previous default.
Landlord's acceptance of Rent following an event of default hereunder shall not
be construed as a waiver of such event of default. No waiver by Landlord of any
breach of this Lease shall constitute a waiver of any other violation or breach
of any of the terms hereof. Forbearance by Landlord to enforce one or more of
the remedies herein provided upon a breach hereof shall not constitute a waiver
of any other breach of the Lease.

      Section 23.04.       No provision of this Lease shall be deemed to have
been waived by Landlord unless such waiver is in writing and signed by Landlord.
Nor shall any custom or practice which may grow tip between the parties in the
administration of the terms of this Lease be construed to waive or lessen
Landlord's right to insist upon strict performance of the terms of this Lease.
The rights granted to Landlord in this Lease shall be cumulative of every other
right or remedy which Landlord may otherwise have at law or in equity or by
statute and the exercise of one or more rights or remedies shall not prejudice
or impair the concurrent or subsequent exercise of other rights or remedies.

      Section 23.05.       Notwithstanding any provision hereunder the contrary,
if Landlord is required to make a repair or perform an obligation hereunder,
Tenant shall provide written notice to Landlord specifying in reasonable detail
the nature of the repair or obligation. Thereafter, if Landlord fails to (i)
commence such repair or performance of such obligation within ten (10) days
after such notice (or of such repair or performance of such obligation cannot
with reasonable diligence be commenced within ten (10) days, such longer period
as is reasonably necessary to commence such repair or perform such obligation,
but in no event more than thirty (30) days after such notice, and (ii)
thereafter prosecute such repair or perform such obligation with due diligence
until such repair is completed or such obligation is performed, then Tenant
shall provide a further written notice to Landlord giving notice of Tenant's
intention to make such repairs or perform such obligations. Thereafter, if
Landlord fails to (i) commence such repair or perform such obligation within
five (5) days and (ii) thereafter prosecute such repair or perform such
obligation with due diligence until such repair or obligation is completed or
performed, then Tenant shall have the right to make such repair or perform such
obligation and deduct the reasonable expenses expended by Tenant in performing
such repair or obligation from the next installments of Base Rent due to
Landlord hereunder.

                  TENANT'S RENEWAL OPTIONS/EXPANSION OPTIONS


      Section 26.01.       Tenant's Renewal Options.
                           ------------------------

             (a)   The Options. Unless Landlord elects to cancel the Lease in
                   -----------
exercise of its cancellation right set forth below, and subject to the further
provisions of this Section and provided that no event of default by Tenant under
this Lease for which Landlord has provided Tenant notice of in writing has
occurred and is continuing under this Lease at the time of exercise of any
renewal option or at commencement of any renewal Term, Tenant shall have and is
hereby given the option to renew and extend this Lease for up to an additional
five (5) year period (Tenant has a one time opportunity to choose a renewal Term
of one (1), two (2), three (3), four (4), or five (5) year term) upon the terms,
covenants, conditions, and provisions herein contained that are in effect as of
the time of the renewal and extension, excepting Rent, to follow consecutively
upon the expiration of the original Term of this Lease. However, Tenant's one-
time opportunity to choose a first renewal Term described herein shall be
subject to and conditional upon the right of Landlord to cancel any renewal of
the original Lease Term. Such cancellation must be exercised by Landlord
providing Tenant with written notice of such exercise at least eighteen (18)
months prior to the expiration of the original Lease Term. If Landlord exercises
the foregoing cancellation right, Landlord shall reimburse Tenant, upon the
expiration of the original Lease Term, for all unamortized costs for remodeling
or other Tenant work in connection with the construction of the initial
Leasehold Improvements, excluding the cost of Tenant's demolition work, based on
a ten (10) year amortization schedule (commencing as of the Rental Commencement
Date) using a 10% interest factor. Tenant shall provide Landlord with a written
statement of such costs of remodeling or other Tenant work, as well as invoices
and other receipts

                                     -38-
<PAGE>
 
relating thereto, if available, as soon as such information is available. The
amortization computation described above will be analogous to the amortization
calculation depicted on Exhibit H (it being agreed, however, that the
calculation depicted on Exhibit H is intended solely to set forth the procedure
for the amortization and does not purport to accurately reflect or estimate the
cost of the Tenant work [excluding the cost of Tenant's demolition work] to be
reimbursable by Landlord as provided hereunder).

             (b)    Method of Exercise. The option contained in Section 26.01(a)
                    ------------------
may be exercised by Tenant's giving Landlord notice of its irrevocable exercise
of the same, and choice of length of renewal Term as provided above, not less
than ten (10) months prior to the expiration date of the original Term hereof.

             (c)    Premises Affected by Renewal. Tenant may renew this Lease
                    ----------------------------
and extend the Term hereof as to all (but not less than all) of the Premises and
the parking spaces that are, on the date of the exercise of the option, subject
to this Lease.

             (d)    Terms of the Renewal. The first renewal and extension of
                    --------------------
this Lease shall be on and under the same covenants, agreements, terms,
provisions, and conditions as are contained herein for the original Term, except
(1) that the Base Rent for purposes of calculating annual Base Rent per square
foot of (i) Net Rentable Area of Existing Space and (ii) Net Rentable Area of
Improvement Space in the Premises and (iii) Net Rentable Area of Basement Space
shall be Market Rental Rate (as defined in Section 26.05) for first-class office
buildings in the suburban area of Houston, whether such be higher or lower,
provided that such Market Rental Rate may not exceed the original Term Base Rent
for (i), (ii), and (iii) above by more than one dollar ($1.00) per square foot.
Any second or third five (5) year renewal Term shall be subject to the
foregoing, except that the one dollar ($1.00) per square foot cap or limitation
shall not apply.

             (e)    If Tenant exercises its one time option for a first renewal
Term, then Tenant shall have an option for a second renewal Term of five years,
and if such foregoing option for a second renewal Term is exercised, then Tenant
shall have an option for a third five year renewal Term. The method of exercise,
premises affected, and terms of renewal for any such second or third five year
renewals shall be as provided in (b) (except that the notice shall be given by
Tenant not less than ten (10) months prior to the expiration date of the
applicable renewal Term), (c), and (d) herein. Any right or option granted to
Tenant hereunder is conditional upon an event of default by Tenant under this
Lease for which Landlord has provided Tenant notice of in writing not having
occurred and being continuing at the time of commencement of any renewal Term.

             (f)    Further Assurances. If Tenant exercises its option to extend
                    ------------------
this Lease in accordance with all the provisions hereof, Landlord and Tenant,
upon request of either, will sign and acknowledge a written memorandum 
evidencing such facts, and

                                     -39-

setting out the date to which the renewal Term will extend, and the Base Rent
will apply during such renewal Term.

      Section 26.02.       Tenant's Expansion Options.
                           --------------------------

             (a)    The Options. So long as no event of default by Tenant under
                    -----------
this Lease for which Landlord has provided Tenant notice of in writing has
occurred and is continuing at the time of delivery of any expansion space, and
subject to the other provisions thereof, Tenant shall have one-time options to
include under this Lease as a part of the Premises certain basement space
designated by diagonal lines on Exhibit I attached hereto (the "B-2 Expansion
Space") (approximately 6,700 square feet) and certain basement space designated
by cross-hatching on Exhibit J (the "B-3 Expansion Space") (approximately 2,000
square feet).

             (b)    Method of Exercise. Tenant may exercise its option to
                    ------------------
include the B-2 Expansion Space effective two (2) years from the Commencement
Date (the "B-2 Expansion Date"), provided that Tenant shall have provided notice
to Landlord in writing of Tenant's exercise of such option six (6) months prior
to the B-2 Expansion Date. Tenant may exercise its option to include the B-3
Expansion Space effective four (4) years from the commencement of the Lease (the
"B-3 Expansion Date"), provided that Tenant shall have notified Landlord in
writing of Tenant's exercise of such option six (6) months prior to the B-3
Expansion Date.

             (c)    Terms of the Expansion. All covenants, terms, provisions, 
                    ----------------------
and conditions of this Lease (with the Base Rent for the B-2 Expansion Space
being the Base Rent per square foot of Net Rentable Area for the Basement Space)
shall apply to any B-2 Expansion Space and B-3 Expansion Space included under
Tenant's expansion options, except that the Base Rent for the B-3 Expansion
Space shall be the Market Rental Rate and the Rent payable for the B-2 Expansion
Space or the B-3 Expansion Space shall commence on the earlier of (i) the date
Tenant occupies and conducts normal business operations from the applicable
Expansion Space or (ii) the date that is thirty (30) days after the applicable
Expansion Date (the "Expansion Space Rental Commencement Date"); provided,
however, that if Tenant is not delivered the Expansion Space to begin any build-
out or remodeling Tenant may wish to do as of the applicable Expansion Date,
then Tenant shall not be obligated to begin paying Rent until the date which is
thirty (30) days after the date upon which Tenant is delivered such space.
Additionally, notwithstanding the foregoing, if Landlord does not deliver either
the B-2 Expansion Space or the B-3 Expansion Space within thirty (30) days after
the B-2 Expansion Date or the B-3 Expansion Date, respectively, then Tenant
shall not be obligated to pay any Rent for such Expansion Space after the
applicable Expansion Space Rental Commencement Date for the number of days that
Landlord was late in delivering such Expansion Space to Tenant beyond thirty
(30) days after the applicable Expansion Date.

                                     -40-
<PAGE>
 
             (d)    Condition of Expansion Space. Subject to all the other terms
                    ----------------------------
and provisions of this Lease, Tenant shall take any expansion space "as is,"
with all faults, except that all building systems shall function in accordance
with their original design intent.

             (e)    Construction of Leasehold Improvements. Any leasehold
                    --------------------------------------
improvements to such space shall be constructed in accordance with Section 3.02,
3.03, and 3.05 and Article 11 of this Lease.

      Section 26.03.       Tenant's Preferential Rights.
                           ----------------------------

             (a)    The Preferential Rights. During the Term of this Lease, so
                    -----------------------
long as no event of default by Tenant under this Lease for which Landlord has
provided Tenant notice of in writing shall have occurred and be continuing, and
subject to the other provisions and conditions of this Section 26.03, Tenant
shall have the preferential right to lease the northeast and northwest quadrants
of the first floor in the Building until such space is leased to another party.
A "quadrant" is approximately one-fourth of a floor calculated as if the floor
were bisected by two lines drawn from the mid-point of both sets of opposite
outer building walls, but excluding central floor service areas, which totals
approximately thirty-five thousand (35,000) square feet of Net Rentable Area.
During the first six (6) months of the Term of this Lease, so long as no event
of default by Tenant under this Lease for which Landlord has provided Tenant
notice of in writing shall have occurred and be continuing, and subject to the
other provisions and conditions of this Section 26-03, Tenant shall have the
preferential right to lease certain space designated by cross-hatching on
Exhibit K attached hereto, or any portion thereof, provided, however, that in
the event Tenant leases only a portion of the space indicated on the attached
Exhibit K, such portion leased by Tenant shall be reasonably configured such
that, based upon customary space planning standards and applicable law, the
remaining portion of space not leased by Tenant would be reasonably leasable to
a prospective tenant. Notwithstanding the foregoing provisions of this Section
26.03(a), it is herein agreed by Tenant that if any portion of the space over
which Tenant has preferential rights under this Section 26.03(a) is occupied by
Landlord (or a related entity of Landlord) as of the Commencement Date, then
such occupied space shall not be subject to Tenant's preferential rights
contained herein until such space becomes unoccupied or until such space is
proposed to be leased to a third-party tenant).

             (b)    Method of Exercise. If Tenant elects to exercise any
                    ------------------
preference right contained herein, then Tenant shall so notify Landlord in
writing and shall describe the space Tenant wishes to lease pursuant thereto.
Additionally, Landlord shall notify Tenant in writing of the material terms and
conditions of any proposed third-party lease before any such space is leased to
a third-party tenant, and Tenant shall have fifteen (15) days

                                     -41-
<PAGE>
 
thereafter to give Landlord notice of the exercise of its preferential right as
to all such space specified in the notice. Except as provided in Section
26.03(a), Tenant may not exercise any preferential rights as to a part only of
the space specified in the notice; provided, however, if the third party lease
covers more space than the northeast and northwest quadrants and Tenant
exercises its preferential right hereunder, if the number of square feet of Net
Rentable Area to be leased by the third party is less than twice the number of
square feet of Net Rentable Area to be leased by Tenant pursuant to its
preferential right herein contained, then Tenant shall only be obligated to (and
Tenant shall have the right to) lease only the northeast and northwest
quadrants.

             (c)    Effect of Non-Exercise. If Tenant elects not to, or fails
                    ----------------------
timely to, exercise any preferential rights as to any given space for which
Tenant has been notified in accordance with Section 26.03(b) hereof that such
space is proposed to be leased to a third-party tenant, then Tenant shall waive
any and all rights as to such space and Landlord shall be free for ten (10)
months to lease such space to such third party upon terms and conditions
substantially no less favorable to Landlord, taken as a whole, than the terms
and conditions stated in the notice. If Landlord fails to consummate such a
lease with such third party within such time period, then the provisions of this
Section 26.03 shall again become operative, and Tenant shall again have the
opportunity to lease such space or portion thereof as herein provided.

             (d)    Terms of Exercise. Landlord and Tenant shall execute an
                    -----------------
amendment to this Lease so that all covenants, terms, provision, and conditions
of this Lease shall apply to any space included under this Lease pursuant to
Tenant's preferential options set forth in this Section 26.03 (with the Base
Rent payable for such space being the Base Rent per square foot of the Net
Rentable Area of either the Existing Space or Improvement Space, depending upon
whether condition of option space to be absorbed into the Premises by Tenant, in
Landlord's and Tenant's reasonable opinion, more closely resembles the
condition, as of the Commencement Date of this Lease, of the Existing Space or
the Improvement Space, provided, however, that the Base Rent per square foot of
Net Rentable Area in the northeast quadrant shall be the Base Rent per square
foot of Net Rentable Area for the Improvement Space, and the Base Rent per
square foot of Net Rentable Area in the northwest quadrant shall be the Base
Rent per square foot of Net Rentable Area for the Existing Space).

      Section 26.04. Except as is otherwise provided in Section 26.03(a), the
expansion rights and preferential rights granted to Tenant pursuant to Sections
26.02 and 26.03 are subordinate only to the rights of Amoco to lease such
expansion space and preference space pursuant to the Amoco Lease as currently
existing; provided, however, that Landlord represents and warrants to Tenant
that Amoco is entitled to only fifteen (15) days after notice of a third-party
tenant's election to lease space in the Building during

                                     -42-
<PAGE>
 
which to decide whether Amoco wishes to exercise such preference right over all
such space.

      Section 26.05  Market Rental Rate. The term "Market Rental Rate" as used
                     ------------------
in this Lease, shall mean the rate (determined on a "net" lease basis in the
same manner as Base Rent is calculated for this Lease) charged to non-
renewing/non-extending tenants for space of comparable size, location and
condition in the Building and in comparable, first-class, low-rise office
buildings in the western suburban area of Houston, Texas that are located South
of Interstate Highway 10, north of Highway 59 and West of Gessner Road (giving

                  (ii)    the use, location, size and floor level(s) of the

             be provided);

                  (v)     abatements (including with respect to base rental,
             operating expenses and real estate taxes, and parking charges);

                  (vi)    the inclusion or exclusion of parking charges in
             rental;

                  (vii)   lease takeovers/assumptions;

                  (viii)  relocation/moving allowances;

                  (ix)    space planning allowances;

                  (x)     refurbishment and repainting allowances;

                  (xi)    club memberships;

                  (xii)   any other concessions or inducements such as rent
             discounts, build out or construction allowance;

                  (xiii)  extent of services provided or to be provided;

                                     -43-
<PAGE>
 
                  (xiv)   distinctions between "gross" and "net" lease (Market
             Rental Rate being calculated on a "net" lease basis);

                  (xv)    base year or dollar amount for escalation purposes of
             all operating expenses, including real estate taxes, and the method
             of calculation used in determining each tenant's share of
             operating expenses for any given period;

                  (xvi)   any other adjustments (including by way of indexes
             such as increases based upon increases of Consumer Price Index) to
             base rental;

                  (xvii)  the extent, if any, to which the credit standing and
             financial stature of the tenant and any guarantors would have an
             impact on operators of comparable buildings;

                  (xviii) term or length of lease;

                  (xix)   the time the particular rental rate under
             consideration was agreed upon and became or is to become effective;

                  (xx)    any leasing commissions and/or fees/bonuses to be paid
             in connection therewith; and

                  (xxi)   except as provided otherwise in this Lease to the
             contrary, any other relevant term or condition in making such
             Market Rental Rate determination.

      Within sixty (60) days of the date upon which Tenant exercises its option
to take on the B-3 Expansion Space, or exercise its second or third Renewal Term
options (if Tenant so elects), Tenant may give Landlord a written notice
requesting Landlord to set forth in writing to Tenant the amount of such Market
Rental Rate, and Landlord shall provide Tenant with such amount in writing
together with reasonable information setting forth how such Market Rental Rate
was determined, within thirty (30) days of Tenant's written request therefor.
Notwithstanding anything else herein to the contrary, Tenant shall not be
required to exercise any such expansion or renewal option until Tenant has
received Landlord's determination of the Market Rental Rate, if requested as
herein provided by Tenant. Any dispute by the parties as to the Market Rental
Rate for the B-3 Expansion Space or the Market Rental Rate applicable during the
second or third Renewal Term, upon written request by Tenant, shall be settled
by arbitration in accordance with this Section 26.05, and any determination as a
result thereof shall be binding upon the parties. Landlord and Tenant shall use
reasonable efforts to agree, within five (5) business days following Landlord's
receipt of a notice from Tenant that

                                     -44-
<PAGE>
 
Tenant disputes Landlord's calculation of Market Rental Rate for the space in
question, upon the appointment of one (1) arbitrator to resolve the matter. If
an agreement on a single arbitrator cannot be reached within such five (5)
business day period, Landlord and Tenant shall each appoint their respective
arbitrator within ten (10) days following the expiration of the five (5) 
business day period and shall specify the name and address of their respective
arbitrator to the other party prior to the expiration of such ten (10) day
period; provided, that if one party fails to specify the name and address of its
selected arbitrator within such ten (10) day period, the arbitrator selected by
the other party shall act as the single arbitrator as if both parties had agreed
to the appointment of such arbitrator as provided above. The selected
arbitrators shall then meet and if such arbitrators are unable to agree upon
such matter, they shall appoint a third arbitrator within ten (10) business days
following their appointment. If the two (2) arbitrators are unable to agree upon
a third arbitrator within such ten (10) business day period, the third
arbitrator shall be appointed as soon as reasonably possible by the American
Arbitration Association (or any successor organization, or if no successor
organization shall then exist, by a court of competent jurisdiction residing in
Harris County, Texas) subject to the qualification requirements set out below.
In the event of the failure, refusal or inability of any arbitrator to act, a
new arbitrator shall be appointed in his stead, which appointment shall be made
in the same manner as set forth above for the appointment of such resigning
arbitrator. Immediately following the selection of the final arbitrator(s), the
arbitrator(s) shall meet and, within fifteen (15) days following the complete
selection of the arbitrators, endeavor to resolve the matter, such fifteen (15)
day period may be extended only to the extent of delay caused by Events of Force
Majeure or if resolution within such fifteen (15) day period is not reasonable
under the circumstances. Within three (3) business days following the selection
of each arbitrator, each party shall submit to such arbitrator such party's
proposed resolution of the matter being arbitrated, together with reasonable
evidence supporting such proposed resolution. The arbitrator(s) shall select
either the proposed resolution of such matter submitted by Landlord or the
proposed resolution of such matter submitted by Tenant, whichever proposal such
arbitrator(s) deem to be the most correct according to the definitions, terms
and requirements set forth in this Lease, with no compromise. The power of the
arbitrators shall be exercised by the concurrence of at least two (2)
arbitrators, except that if only one arbitrator is required, the decision of
such arbitrator shall govern. The arbitrator(s) shall resolve the controversy
and shall execute and acknowledge their decision, together with a brief
statement describing the rationale for such decision, in writing and deliver a
copy thereof to each of the parties personally or by registered or certified
mail, return receipt requested. If the arbitrators fail to reach an agreement
during such fifteen (15) day period, they shall be discharged, and new
arbitration proceedings shall commence, which appointments shall be made in the
same manner as set forth above. By agreement in writing, Landlord and Tenant may
extend the time to reach agreement either before or after the expiration
thereof. The non-prevailing party shall be assessed with all of the costs and
expenses of the arbitration. Each arbitrator shall be a real estate broker

                                     -45-
<PAGE>
 
licensed under the laws of the State of Texas, shall be a member of the Society
of Office or Industrial Realtors (or any successor or equivalent organization
then existing), and shall have been actively and continuously engaged in leasing
transactions involving office space in Houston, Texas for the immediately
preceding ten (10) year period. Until the arbitration proceedings have
concluded, if the Tenant has begun to pay Base Rent for such space, the Base
Rent payable by Tenant shall be the Base Rent proposed by Landlord in its notice
to Tenant provided, however, that upon the final determination of the Market
Rental Rate by the arbitrators, the difference between the Base Rent paid by
Tenant and the correct Base Rent shall be refunded by Landlord to Tenant or paid
by Tenant to Landlord, as the case may be, within ten (10) days of the
determination of the correct Rent, together with interest thereon at the prime
rate from the date owed or paid, as the case may be, until paid or returned, as
the case may be.

to display its name (or their names as the case may be) on the Sign Monument.

      Section 27.18.       Notwithstanding anything to the contrary contained in
this Lease, Landlord does hereby waive, relinquish and discharge all liens and

Mr. J. Michael Stewart
Texas Microsystems, Inc.

Houston, TX 77242


Dear Michael:


On behalf of Sequoia Systems, Inc., it is my pleasure to offer you the position 
of Executive Vice President of Sequoia and President of the TMI/TME division 
based at TMI's headquarters in Houston, Texas, commencing with the closing of 
Sequoia's acquisition of TMI/TME. Your starting salary will be $7,211.54 (which 
calculates to $187,500 annually) paid bi-weekly. Your salary will be reviewed 
on an annual basis. This position reports directly to me.

You will be entitled to all employee benefits, including group insurance, 
employee stock purchase plan, 401(k) plan, etc., normally extended to new 
Sequoia employees. Additionally, as an officer of Sequoia, you will receive an 
additional executive life insurance policy of two times your base salary. You 
should understand and agree that your employment is governed by the employee 
policies and practices of Sequoia and that you will be an employee at will 
rather than for any fixed period of time.

You will be eligible to participate in Sequoia's Officer Incentive Compensation 
Plan targeted to provide additional earnings potential, dependent on achievement
of individual goals and the financial results of the new company, on the same 
basis as other Sequoia officers. For FY94, such incentive compensation was 
generally in the range of 30-60% of base salary.

This offer is contingent upon your completing and signing several documents, as 
well as the closing of Sequoia's acquisition of TMI/TME. You must sign a 
Proprietary Information and Inventions Agreement, and you should complete a 
Direct Deposit form. Additionally, we will provide you with a copy of Form I-9, 
which must be completed by all newly hired employees.

Please indicate your acceptance by signing and returning the copy of this letter
to me, together with the signed copy of the Proprietary Information and 
Inventions Agreement.

Please call me with any particular questions regarding this offer. You may 
contact Don Colanton, Director of Human Resources, for additional information 
concerning Sequoia benefits.

The Board of Directors and the management team at Sequoia join me in enthusiasm 
at the prospect of your joining Sequoia.



Sincerely,



Neil McMullan
President & CEO



I accept your offer of employment with Sequoia Systems, Inc.
