                                     PART I

ITEM 1.  BUSINESS

     ADC Telecommunications, Inc. designs, manufactures and markets a broad
range of transmission and networking systems and physical connectivity products
for broadband telecommunications networks utilizing copper and fiber optic
transmission media.  The Company markets its products worldwide through its own
direct sales force, as well as through distributors, dealer organizations and
original equipment manufacturers (OEMs). The Company's products are designed for
use in the public telecommunications networks maintained by telephone operating
companies, interexchange carriers, other telecommunications common carriers and
broadcast and cable TV networks, and for use in private telecommunications
networks maintained by large businesses, government agencies, and educational
and other non-profit institutions.

     The Company was incorporated in 1953 as a Minnesota corporation under the
name Magnetic Controls Company.  In 1961, Magnetic Controls Company was merged
with ADC Incorporated, a Minnesota corporation incorporated in 1935.  In 1984,
the Company sold substantially all of the assets of its magnetics operations.
In 1985, Magnetic Controls Company changed its corporate name to ADC
Telecommunications, Inc. in order to better reflect the Company's commitment to
the telecommunications market and to identify the Company more closely with its
ADC trademark.

     In July 1989, ADC acquired Kentrox Industries, Inc. (Kentrox), a
manufacturer of public network service access equipment for private
telecommunications networks, located in Portland, Oregon.  In June 1990, the
Company acquired technology and other assets of TELINQ Systems Incorporated,
located in Richardson, Texas.  The ADC TELINQ Development Center-SM- (TELINQ) is
an advanced development center for ADC and is responsible for developing high
speed digital transmission products.  In July 1990, ADC acquired American
Lightwave Systems, Inc. (ALS).  ALS, located in Meriden, Connecticut, designs,
manufactures and markets fiber optic video transmission equipment for the
telephone, cable television, broadcast and government

<PAGE>

markets.  In May 1991, the Company acquired Fibermux Corporation (Fibermux),
located in Chatsworth, California.  Fibermux designs, manufactures, markets, and
installs enterprise-wide communication systems for the interconnection and
transport of Local Area Network (LAN) and other voice, data and video traffic,
primarily in private telecommunications networks.  As used herein, the terms
"Company" and "ADC" refer to ADC Telecommunications, Inc. and its wholly-owned
subsidiaries unless the context requires otherwise.

THE TELECOMMUNICATIONS MARKET

     The largest market for the Company's broad range of telecommunications
products consists of companies providing service in the public
telecommunications networks and the OEMs which supply such companies.  The
Company's transmission and physical connectivity products for the public network
market are primarily located in central transmission facilities (i.e., in
telephone company networks, central office and outside plant facilities which
contain the equipment used in switching and transmitting incoming and outgoing
telephone circuits to complete local and long distance telephone connections).

     Another market for the Company's products consists of rapidly growing
private voice, data and video telecommunications networks maintained by
businesses, government agencies, and educational and other non-profit
institutions.  The Company's customers in this market primarily include large
businesses and government agencies with their own communications networks and
the OEMs and Value Added Resellers (VARs) which supply such networks.  The
Company's products for private networks are located on the private network
customers' premises and consist of enterprise-wide communication systems and
public network service access equipment.

     The market for the Company's products has grown in large part due to the
effects of three ongoing developments in the telecommunications industry.
First, rapid technological change has created a demand for new products
employing advanced technologies.  Second, the shift to data and video network
traffic has resulted in increasing demand for voice, data and video networking



                                        2

<PAGE>

capabilities within private networks and, more recently, over the public
networks as well.  Third, the policy of deregulation being followed by the
Federal Communications Commission and other similar regulatory agencies
throughout the world has increased opportunities for independent companies to
supply products and services within public telephone system markets and within
private voice, data and video communications markets.

     The Company believes that for the foreseeable future technological change
will be the most important development in the continuing evolution of the
telecommunications market.  One important technological change in the past
decade has been the increasing replacement of analog technology with digital
technology in transmission networks.  In analog technology, information is
converted to a voltage or current wave form for processing or transmission.  In
digital technology, information is converted to digital bits and then processed
or transmitted using computer-based components.

     A second important change in transmission technology has been the
introduction of fiber optic systems, which are based on a physical property of
light that allows transmission of light pulses in a coded analog or digital
format through a glass fiber approximately the size of a human hair.  Fiber
optic systems are increasingly replacing copper-based transmission systems
because of their capacity to carry large volumes of information at high speeds,
their small size and their insensitivity to electromagnetic interference.

     A third important technological change in the telecommunications
marketplace is in the use of integrated circuits and miniaturization, which has
facilitated the transfer of certain telecommunications functions from central
switching and transmission locations to locations closer to the business or
residential end-user.  In addition, because of the increased use of integrated
circuits in both public and private telecommunications, networks have become
significantly more complex.  Increasingly, high speed switching, network
performance monitoring, information compression, and data translation functions
are being performed by network equipment.  The Company believes that over the
long term, the majority of new equipment purchased by telephone operating



                                        3

<PAGE>

companies and private network customers will employ digital technology and that
a significant portion of such equipment will utilize the fiber optic
transmission medium.

PRODUCTS

     The Company categorizes its products into the following groups:

     TRANSMISSION PRODUCTS:  Transmission products permit and enhance the
generation of electronic and optical signals over a telecommunications circuit.
Certain of the transmission products also provide access in order to monitor,
test and reroute circuits within telecommunications transmission systems.  ADC's
transmission products are designed for use in copper-based and fiber optic
transmission systems.

     NETWORKING PRODUCTS:  Networking products provide interconnection and
transportation of voice, data and video signals within a single customer
building or campus as well as network access to the public network.  The
Company's networking products are designed for use in copper-based and fiber
optic networks.

     BROADBAND CONNECTIVITY PRODUCTS:  Broadband connectivity products provide
the physical connectivity (contact points) for connecting different
telecommunications system components and gaining access to telecommunications
system circuits by electromechanical means for the purpose of testing,
monitoring or reconfiguring such circuits.  A majority of the Company's
broadband connectivity products are designed for use in copper-based
transmission systems, with the remainder designed for use in fiber optic
transmission systems.

     Historically, most of the Company's products have been used in connection
with copper-based telecommunications systems, reflecting the historical
installed base of equipment utilizing copper cable in domestic and international
telecommunications networks.  As a direct result of this large installed base,
the Company expects that, for the foreseeable future, a substantial portion of
its existing and new products will be sold to maintain and improve the
functionality of copper-based telecommunications systems.  Although the Company
expects to continue to allocate considerable resources to improving existing and
developing new products for these systems, it will also devote significant
resources to the development of fiber optic products because the



                                        4

<PAGE>

Company believes that such products represent an increasing source of future
growth of broadband connectivity product revenues.

     The percentages of total consolidated net sales attributable to each of the
Company's product groups and to fiber optic products in total for the past three
fiscal years are set forth in Part II, Item 7 hereof.  As used herein, "copper
products" refer to products used in copper-based telecommunications systems,

Technologies, Inc., Northern Telecom, Inc., Alcatel Alsthom Compagnie Generale
D'Electricite, NEC America, Inc., Fujitsu Limited and Tellabs Operations,
Inc.).  The Company sells its products to most of the major providers and OEMs.

     The private network market includes predominantly large businesses and
state and federal government agencies which own and operate their own voice and
data networks for internal use.  The major OEMs in this market include
International Business Machines Corporation (IBM), AT&T Paradyne Corporation,
Digital Equipment Corporation, Northern Telecom, Inc., Codex Corporation and
Racal Corporation.

     The Company's products are sold in the United States by approximately 112
field sales representatives located in 24 sales offices throughout the country,
and by several dealer organizations and distributors.  The Company also has a
customer service group, which supports field sales personnel and is responsible
for application engineering, customer training, entering orders and supplying
delivery status information, and a field service engineering group, which
provides on-site service to customers.

     The foreign markets with the greatest potential for sales of the Company's
products consist of the telephone operating companies in the public
telecommunications networks of Canada, Western Europe, Australia, New Zealand,
Mexico and the Asian region.  The Company sells its products to foreign
customers through 23 Company-employed field salespersons, eight foreign
independent sales representatives and 81 foreign distributors.  On October 31,
1993, the Company's foreign distribution network was selling products in 61

     Consolidated export sales to unaffiliated customers for fiscal years 1993,
1992 and 1991 were $58,919,000, $49,347,000 and $37,960,000, respectively
(approximately 16.1%, 15.6% and 12.9%, respectively, of consolidated net sales).

     The Company warrants most of its products against defects in materials and
workmanship under normal use and service for periods of up to 15 years.  To
date, the Company's warranty experience has been favorable, with a low rate of
product return.

COMPETITION

     Competition in the telecommunications products market is intense.  The
Company manufactures, markets and sells products similar to those manufactured
by numerous other companies, some of which, such as AT&T Technologies, Inc. and
Switchcraft, Inc., a subsidiary of Raytheon Company, have greater resources than
those available to the Company.  The Company faces increasing competition from a
number of other smaller competitors.  The Company believes its success in
competing with other manufacturers of telecommunications products depends
primarily on its engineering, manufacturing and marketing skills, the price,
quality and reliability of its products, and its delivery and service
capabilities.

     The Company's Fibermux subsidiary competes with a number of other
companies, none of which is dominant, and faces both strong price competition
and pressure from alternative distribution strategies utilized by these other
companies.  The Company's Kentrox and ALS subsidiaries have various competitors,
none of which is dominant.

     The Company believes that technological change, the shift in network
traffic to data and video and continuing industry deregulation will continue to
cause rapid evolution in the competitive environment of the telecommunications
market, the full scope and nature of which is impossible to predict at this
time.  The Company believes the most significant competitive effect of
continuing



                                       14

<PAGE>

industry deregulation has been, and will continue for the immediate future to
be, the creation of new opportunities for suppliers of telecommunications
products like the Company.  The Company expects, however, that such
opportunities will attract increased competition from others as well.  In
addition, the Company expects that AT&T Technologies, Inc. will continue to be a
major supplier to the Bell Operating Companies, and is competing more
extensively outside the Bell system.  The Company also believes that the rapid
technological changes which characterize the telecommunications industry will
continue to make the markets in which the Company competes attractive to new
entrants.

MANUFACTURING AND SUPPLIES

     The manufacturing process for the Company's electronic products consists
primarily of assembly and test of electronic systems built from fabricated
parts, printed circuit boards and electronic components.  The manufacturing
process for the Company's electromechanical products consists primarily of
fabrication of jacks, plugs, and other basic components from raw materials,
assembly of components and testing.  The Company's sheet metal, plastic molding,
stamping and machining capabilities permit the Company to configure components
to customer demand.

     The Company purchases raw materials and component parts, consisting
primarily of copper wire, optical fiber, steel, brass, nickel-steel alloys,
gold, plastics, printed circuit boards, solid state components, discrete
electronic components and similar items, from several suppliers.  Although a
number of components used by the Company are single sourced, the Company has
experienced no significant difficulties to date in obtaining adequate quantities
of these raw materials and component parts.  The Company believes that
alternative sources of supply exist, or can be developed without causing
significant delays, for all of its raw materials and component parts.

     The 1993 and 1992 increases in net sales of transmission products are
primarily attributable to sales of new products and, in 1993, increased sales of
fiber video delivery systems to public



                                       22

<PAGE>

telecommunications network providers.  The Company intends to continue
introducing new transmission products in 1994.  If such new products meet with
reasonable market acceptance, the Company anticipates that net sales of all
transmission products will grow as a percentage of the Company's total net
sales.

     The 1993 increase in net sales of networking products primarily represents
increased sales of public network access equipment to private network customers.
The 1992 increase in net sales of networking products primarily reflects the
acquisition of Fibermux in May 1991.  Due to the timing of the acquisition,
Fibermux product revenues were included in net sales of networking products
for all of 1993 and 1992 and for six months in 1991.

     Although the Fibermux acquisition contributed to increased net sales and
orders during all of 1992 and the last six months of 1991, net sales and orders
for the Company as a whole were lower than anticipated during that 18-month
period due to the effects of recession in the public network market.  These
effects are reflected in the 1992 decrease in net sales of broadband
connectivity products.  The Company began experiencing improvement in its public
network market business during the second quarter of 1992 which continued
throughout the remainder of 1992 and 1993.

     Within the broadband connectivity product group, net sales of ADC's copper
products utilizing telephone jacks have declined as a percentage of total net
sales during the last three years as shown in the following table:
<TABLE>

                                                 ------------------------------

<S>                                               <C>       <C>       <C>
DSX products                                       28.7%     29.0%     35.5%

  component products                                4.5       5.7       7.0

</TABLE>

     Although these products currently account for a substantial portion of the
Company's revenues, management believes that future sales of copper products
utilizing telephone jacks will continue gradually to decline as a percentage of
total net sales primarily due to the ongoing evolution of technologies within
the telecommunications marketplace (see Item 1 Business -- The
Telecommunications Market) and the addition of new products to the ADC product
portfolio.

     Net sales of fiber optic products represented 34.2%, 29.9% and 20.9% of
total net sales in 1993, 1992 and 1991, respectively.  These year-to-year
increases reflect the Company's increasing emphasis on development and marketing
of fiber optic products.  Management anticipates increasing the Company's fiber
optic product offerings which should expand total sales of such products.



                                       23

<PAGE>

     GROSS PROFIT:  The 1993 and 1992 increases in gross profit percentage to
51.2% and 51.0% of net sales, respectively, from 49.4% of net sales in 1991
primarily reflect more favorable product sales mix, successful manufacturing
cost reduction efforts and higher net sales volumes.

     OPERATING EXPENSES:  Total operating expenses represented 36.7%, 38.8% and
36.3% of net sales in 1993, 1992 and 1991, respectively.  The 1992 increase
primarily reflects the first full year of Fibermux operating expenses, and a
$3,800,000 personnel reduction charge ($.09 per share after taxes) recorded in
the Company's first quarter 1992.  This charge represented employee separation
costs related to the elimination of positions during that quarter.

     The 14.8% and 14.5% increases in selling expenses in 1993 and 1992,
respectively, also reflect increased marketing and selling activities associated
with new product introductions and expansion of markets.


     The 13.7% and 11.6% increases in development and product engineering
expenses in 1993 and 1992, respectively, also reflect significant investments
in product development and introduction.  The Company has been able to maintain
its development and product engineering expenses as a relatively constant
percentage of net sales during the 1991 to 1993 period by planning for and
controlling such expenditures.

     The 5.7% and 4.1% increases in administration expenses in 1993 and 1992,
respectively, primarily reflect the growth of the Company.  Due to effective
management of expenditures, the Company has decreased its ratio of
administration expenses as a percentage of net sales over the three-year period.



     The major technological changes underway in the telecommunications industry
(see Item 1 Business -- The Telecommunications Market) will require the Company
to continue investing significantly in product development.  Company management
recognizes the need to balance the cost of product development with expense
control and remains committed to minimizing the rate of increase of such
expenses.

     OTHER INCOME (EXPENSE), NET:  The interest income (expense) category
reflected net interest income earned on cash balances during 1993 and the
Company's first two quarters of 1991. In May 1991, the Company borrowed $40
million to acquire Fibermux, resulting in net interest expense from that date
through 1992. (See "Liquidity and Capital Resources" below for a discussion of
the Company's borrowings.)

                                       24

<PAGE>

     Other expense primarily represented amortization of the goodwill portions
of the Fibermux, Kentrox and ALS acquisition prices, beginning at their
respective acquisition dates.

     INCOME TAXES:  See Note 6 to the Consolidated Financial Statements
included in Part II, Item 8 of this report for a reconciliation of the federal
statutory tax rate to effective tax rates of 36%, 39% and 40% in 1993, 1992 and
1991, respectively.  In addition to the non-deductible goodwill amortization
amounts discussed above which impact all three years, the 1993 rate reflects a
1% higher federal statutory rate as well as the beneficial impact of tax
credits.

     In February 1992 the Financial Accounting Standards Board issued Statement
No. 109, "Accounting for Income Taxes" (FASB 109), which the Company intends to
implement in the first quarter of 1994.  Management has determined that the
impact of adopting FASB 109 will not be significant to the Company in fiscal
1994.

     NET INCOME:  For the year ended October 31, 1993, net income of
$31,636,000, or $1.15 per share, represented a 50.5% increase over net income
for the year ended October 31, 1992 of $21,026,000, or $.78 per share.  Net
income for 1992 represented a 4.5% decrease from 1991 net income of $22,025,000,
or $.82 per share.

LIQUIDITY AND CAPITAL RESOURCES

     Cash and cash equivalents, primarily short-term investments in commercial
paper with maturities of less than 90 days, decreased $4,160,000 and $9,625,000
during 1993 and 1992, respectively, and increased $4,131,000 during 1991.  In
1993 and 1992, property and equipment additions and long-term debt repayments,
offset by cash generated from operating activities, represented the majority of
the decreases.  The Company's Fibermux acquisition utilized approximately $10
million of cash generated by operating activities and $39 million of long-term
debt in 1991.  Repayment of the Fibermux and other long-term debt consumed
approximately $13 million and $31 million of cash during 1993 and 1992,
respectively.  The other major use of cash generated by operating activities was
property and equipment additions which expenditures approximated $21 million,
$16 million and $25 million in 1993, 1992 and 1991, respectively.

     The Company may borrow up to $40 million under revolving credit agreements.
Borrowings under these agreements bear interest at floating short-term market
rates, can be repaid any time without penalty and can be converted to term loans
bearing interest principally at the prime rate, payable in annual installments
through December 2000.  In May 1991, the Company's



                                       25

<PAGE>


acquisition of Fibermux was partially financed by borrowing the total $40
million.  The full $40 million was outstanding until April 1992, when the
Company began repaying the debt.  At October 31, 1993, all revolving credit
borrowings had been repaid, $40 million of revolving borrowing remained
available to the Company and its long-term debt to total capitalization ratio
was .4%.  The long-term debt to total capitalization ratio was 7.2% at October
31, 1992.

     Management expects that cash generated from operating activities plus
borrowings available under revolving credit agreements will be adequate to fund
operating requirements and property and equipment expenditures in 1994.
However, management recognizes the dynamic nature of the telecommunications
industry and the possibility that one or more of the Company's product
initiatives may achieve strong market acceptance during the year.  In such
event, the Company would consider appropriate financing alternatives.  Total
property and equipment additions for 1994 are expected to be approximately $25
million.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To ADC Telecommunications, Inc.:

     We have audited the accompanying consolidated balance sheets of ADC
TELECOMMUNICATIONS, INC. AND SUBSIDIARIES as of October 31, 1993 and 1992, and
the related consolidated statements of income, changes in stockholders'
investment and cash flows for each of the three years in the period ended
October 31, 1993.  These financial statements and the schedules referred to
below are the responsibility of the Company's management.  Our responsibility is
to express an opinion on these financial statements and schedules 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 financial statements referred to above present fairly,
in all material respects, the financial position of ADC Telecommunications, Inc.
and Subsidiaries as of October 31, 1993 and 1992, and the results of their
operations and their cash flows for each of the three years in the period ended
October 31, 1993, in conformity with generally accepted accounting principles.

     Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedules to
consolidated financial statements are presented for purposes of complying with
the Securities and Exchange Commission's rules and are not part of the basic
consolidated financial statements.  These schedules have been subjected to the
auditing procedures applied in the audits of the basic consolidated financial
statements and, in our opinion, fairly state in all material respects the
financial data required to be set forth therein in relation to the basic
consolidated financial statements taken as a whole.

(2)  ACQUISITIONS:

Effective May 6, 1991, the Company acquired Fibermux Corporation (Fibermux).
During the third quarter of 1990, the Company acquired technology and other
assets of TELINQ Systems Incorporated and the stock of American Lightwave
Systems, Inc. (ALS). Payments and accruals related to these acquisitions through
October 31, 1993, totalled  $74,463,000.

These acquisitions have been accounted for as purchases, and, accordingly, the
total purchase prices were allocated to the net assets acquired based on
estimated fair values at the dates of the acquisitions.  The excess of cost over
the net assets has been recorded as goodwill.  The results of operations have
been included in the Consolidated Statements of Income from the respective
acquisition dates.  The inclusion of financial data for these acquisitions prior
to the dates of acquisition would not have materially affected reported
results.

(3) DEBT:

Under revolving credit agreements, the Company has credit arrangements which
permit borrowing, on an unsecured basis, up to $40,000,000 through December
1996, principally at prevailing market rates of interest.  The agreements
require, among other matters, that the Company meet certain defined net worth,
interest coverage and liability to equity ratios, and restrict cash dividends.
The Company was in compliance with these covenants at October 31, 1993.  The
revolving credit borrowings can be repaid at any time prior to maturity without
penalty.  At maturity, the Company will have an option to convert any
outstanding revolving credit loan balances to term loans bearing interest
principally at the prime rate, payable  in annual installments through December
2000.  The Company is required to pay commitment fees based upon the average
unused amounts of the commitments.  There are no compensating balance
requirements.

In May 1991, the Company borrowed $40,000,000 under the revolving credit
agreements to partially finance the acquisition of Fibermux.  The debt
outstanding under such agreements was repaid during 1993 and 1992.  The weighted
average annual interest rates during the period borrowings were outstanding were
4.9%, 5.3% and 6.6% for 1993, 1992 and 1991, respectively.

At October 31, 1993 and 1992, the Company had a mortgage note payable of
$1,100,000 and $1,434,000 respectively, collateralized by certain land,
buildings and equipment.  The note is payable in annual installments of
approximately $300,000 through 1996 and bears interest at a rate of 7.55%.

knowledgeable outside directors.  The plan provides for granting of a maximum of
110,000 nonqualified stock options at the fair market value.


During 1993, 1992, and 1991, the Company issued shares of common stock to
certain employees which are restricted as to their transferability through
October 31, 1996.  The market value of such stock at the date of issuance is
being amortized to income over the restricted period.  The unamortized amount of
the resulting deferred compensation is recorded as a reduction of shareholders'
investment.  In addition, the Company awarded stock retention bonuses which
provide for cash payments to offset the personal income taxes incurred upon the
lapsing of stock restrictions.  The compensation expense associated with this
plan was $1,938,000, $1,008,000 and $970,000 in 1993, 1992 and 1991,
respectively.

</TABLE>


(5)  CAPITAL STOCK:

     AUTHORIZED STOCK - The Company is authorized to issue 50,000,000 shares of
     common stock at 20 cents par value and 10,000,000 shares of preferred
     stock, no par value.  The Board of Directors has the power to determine the
     dividend, voting, conversion and redemption rights of each series of
     preferred stock which they may create.  There are no preferred shares
     issued.

     STOCK SPLIT - On May 26, 1993, the Company declared a two-for-one stock
     split effected in the form of a 100% stock dividend paid June 28, 1993 to
     shareholders of record as of June 15, 1993.  The share and per share
     information in this report (except balance sheet data) have been adjusted
     to reflect the effect of the dividend.

     SHAREHOLDER RIGHTS PLAN - The Company has a Shareholder Rights Plan which
     provides that if any person or group acquires 20% or more of the Company's
     common stock, each Right not owned by such person or group will entitle its
     holder to purchase, at the Right's then-current purchase price ($16 2/3 at
     October 31, 1993), common stock of the Company having a value of twice the
     Right's purchase price.  The Rights would not be triggered, however, if the
     acquisition of 20% or more of the Company's common stock is pursuant to a
     tender offer or exchange for all outstanding shares of the Company's common
     stock which is determined by the Board of Directors to be fair and in the
     best interests of the Company and its shareholders.  If the Board of
     Directors determines that a 10% shareholder's interest is likely to have an
     adverse effect on the long-term interests of the Company and its
     shareholders, the Rights may also become exercisable.  The Rights are
     redeemable at 1 2/3 cents any time prior to the time they become
     exercisable.  The Rights will expire on October 6, 1996 if not previously
     redeemed or exercised.

     The components of the provision for income taxes are as follows:

</TABLE>

The Company records a reduction in income taxes payable for qualifying tax
credits in the year in which they occur.

The benefit for deferred taxes is primarily due to timing differences in the tax
deductibility of employee benefit plan costs, depreciation and certain accrued
expenses and reserves which are not yet deductible for income tax purposes.

The effective income tax rate differs from the Federal statutory rate as
follows:

</TABLE>

In February 1992 the Financial Accounting Standards Board issued Statement
No. 109, "Accounting for Income Taxes" (FASB 109), which the Company intends to
implement in the first quarter of 1994.  Management has determined that the
impact of adopting FASB 109 will not be significant to the Company in fiscal
1994.

The Company's United States income tax returns for the years 1990 and 1991 are
currently under examination.  Management believes that adequate provision for
income taxes has been made for all years through 1993.

(7)  COMMITMENTS AND CONTINGENCIES:

     OPERATING LEASES - A portion of the Company's operations are conducted

</TABLE>


     CONTINGENCIES - The Company is exposed to a number of asserted and
     unasserted potential claims encountered in the normal course of business.
     In the opinion of management, the resolution of these matters will not have
     a material adverse effect on the Company's financial position or results of
     operations.

     CHANGE OF CONTROL - The Board of Directors has approved the extension of
     certain employee benefits, including salary continuation to key employees,
     in the event of a change of control of the Company.  The Board has retained
     the flexibility to cancel such provisions under certain circumstances.

(8)  PERSONNEL REDUCTION:

     During the first quarter of 1992, the Company recorded a one-time charge
     associated with a workforce reduction program designed to reduce payroll
     costs.

Committee is authorized to make all decisions as required in administration of
the Plan and to exercise its discretion to define, interpret, construe, apply,
and make any exceptions to the terms of the Plan.

IV.  ELIGIBILITY

The Committee will establish rules of eligibility for participation in the Plan
and determine eligibility in accordance with those rules.  Participation will be
effective as of the date approved by the Committee and will be communicated to
the participant by an incentive opportunity statement ("Participant Form")

   Corporate Revenue                                 40%

   Management                                        20%

   Business Unit Operating Income                                   35%

*  Business Unit Customer Service/Inventory

</TABLE>

The goals relevant to you are specified on the attached Participant Form.


*    CORPORATE AND BUSINESS UNIT CUSTOMER SERVICE/INVENTORY TURN MANAGEMENT
goals measure the company's ability to deliver products to meet customer's
request dates while also effectively managing inventories.  Customer
service/inventory turn management is measured by average inventory turns (the
direct cost of goods sold divided by average direct inventory cost) and by
shipping performance (relative to meeting customer request dates).  A single
numerical representation of customer service/inventory management is derived by
multiplying the average inventory turn by the percentage of customer request
dates met by ADC.

     For example, if ADC's average annual inventory turns is 3.4 and the
percentage of customer request dates met is 78%, the result is a customer
service/inventory turn management achievement of 2.65.

                    Average inventory turns           3.4
                    % customer request dates met       .78

                    Result                            2.65

VII. COMPANY PERFORMANCE MINIMUM PAYOUT REQUIREMENTS

The following minimum Company performance goals must be met to assure protection
of shareholder interest before an incentive payout can be generated.

A.   Incentive payments will be made only if net profits are in excess of a
     threshold rate of return on stockholders' equity.  This rate has been
     established at 10%, after tax, based on stockholders' equity at the
     beginning of the fiscal year.

B.   CORPORATE PARTICIPANTS must meet threshold corporate revenue OR corporate
     operating income goals.  BUSINESS UNIT PARTICIPANTS must meet threshold
     business unit revenue OR business unit operating income OR corporate
     operating income goals.

<PAGE>

VIII.  CALCULATION OF PAYMENTS

A.   DETERMINATION OF ACHIEVEMENT AGAINST GOALS AND OBLIGATION TO MAKE PAYMENTS.
The obligation to make payments under the Plan will be determined by achievement
of Corporate and Business Unit goals determined by the Board of Directors.

B.   CALCULATION OF INDIVIDUAL PAYMENTS UNDER THIS PLAN IS A FUNCTION OF:

1.   Target incentive opportunity - expressed as a percentage of an individual's
     FY 1993 earnings.  The target % for each participant is designated on the
     "Participant Form".

2.   Participant's 1993 fiscal year base salary earnings

3.   Corporate performance against the established goals (Corporate Participant)
     Corporate and Business unit performance against the established goals
     (Business Unit Participant)

4.   Individual performance may or may not be used to adjust incentive awards.
     An individual award can be factored plus or minus 50% in increments of 1%
     to account for individual performance.

C.   HOW INDIVIDUAL AWARDS ARE DETERMINED IS SHOWN BY THE FOLLOWING EXAMPLES:

Assume we have a Plan participant with the following facts:

Grade:                                       15
Target Payout:                               11% of base salary earnings
Base Salary Earnings:                        50,0000

<PAGE>

D.   LIMITATION OF RIGHT PRIOR TO RECEIPT OF PAYMENT.  No participant entitled
to receive payment under the calculation determined by this Section VII and VIII
will have any right to pledge, assign, or otherwise dispose of any unpaid
portion of such payment.

IX.  EFFECT OF CHANGE IN EMPLOYMENT STATUS

A.   VOLUNTARY RESIGNATION.  A participant who voluntarily resigns full-time
employment prior to the end of the Fiscal year will relinquish all right to any
payment under the Plan.

B.   CHANGE BASED UPON UNSATISFACTORY JOB PERFORMANCE.  A participant who is
involuntarily terminated or transferred to a non-eligible position for reasons
of unsatisfactory job performance will relinquish all right to any payment under
this plan.

C.   CHANGE BASED UPON JOB ELIMINATION.  Subject to the approval of the
Committee, a participant who is involuntarily terminated or transferred to a
non-eligible position because of a job elimination may retain the right to a
pro-rata payment based upon the time served in the eligible position during the
fiscal year.

D.   CHANGE BASED UPON A PROMOTION / DEMOTION.  A current participant who is
promoted or demoted from an incentive eligible position to another incentive
eligible position during the fiscal year will have a pro rata calculation of
payment based upon the time served in each position during FY 93.

E.   CHANGE BASED UPON TRANSFER BETWEEN CORPORATE AND BUSINESS UNIT PARTICIPANT
CATEGORIES.  A current participant who transfers between Corporate and Business
Unit or between different Business Units with different goals during FY 93 will
have a pro rata calculation based on the goals and length of time spent in the
respective participant categories.

X.   AMENDMENT OR TERMINATION OF PLAN

The Board of Directors reserves and retains the right to modify, rescind or
terminate this plan in whole or in part, at its sole discretion, and nothing in
this Plan limits this right in any way or creates any rights in any employee of
future participation in this Plan or any other plan, or constitutes any
guarantee of compensation or employment with ADC.  Further, neither the Board of
Directors nor the Company has any obligation under this Plan or otherwise to
adopt this or any other plan in any future fiscal year.

                                FISCAL YEAR 1993



<PAGE>

I.    PLAN NAME AND EFFECTIVE DATE

The name of this Plan is the FITL Management Incentive Plan of ADC
Telecommunications, Inc. ("Company") - Fiscal Year ("FY") 1993, effective
November 1, 1992 through October 31, 1993.

II.   PURPOSE

The purpose of the Plan is to provide, with full regard to the protection of
shareholders' investments, a direct financial incentive for eligible full-time
management employees to strive continually to perform an effective leadership
role and make a significant contribution to the FITL (Fiber in the Loop)
Division and the Company's established goals.

III.  ADMINISTRATION

This Plan will be administered by a Management Incentive Plan Committee
("Committee") appointed and authorized by the Company's Board of Directors.
Subject to the complete and full discretion of the Board of Directors, the
Committee is authorized to make all decisions as required in administration of
the Plan and to exercise its discretion to define, interpret, construe, apply,
and make any exceptions to the terms of the Plan.

IV.   ELIGIBILITY

The Committee will establish rules of eligibility for participation in the Plan
and determine eligibility in accordance with those rules.  Participation will be
effective as of the date approved by the Committee and will be communicated to
the participant by an incentive opportunity statement ("Participant Form")
specifying the target incentive level for the position held by the participant.
No part-time employee will be eligible for the Plan, and no employee will become
a participant in the Plan after May 1, 1993.

V.    TIME OF PAYMENT

Payments which become due under this Plan will be made as soon as
administratively feasible following the  close of the Company's fiscal year.

VI.   PLAN GOALS

The Plan reinforces annual goals which support the FITL Division's and the
Company's  long-term strategic plan.  The FY 1993 goal categories and weights
for FITL Management Incentive Plan participants are as follows:

      Corporate Operating Income             20%
      FITL Market Development                40%
      FITL System Development                40%

VII.  OVERALL PLAN OPERATION

As stated in Section VI above, 20% of the weight for each participant's
incentive is based on the Company's operating income results.  The corporate
operating income goals appear on an Attachment to this document.

Achievement on each of the two FITL components of this Plan, i.e., Market
Development and System Development, is expressed in terms of point values.  For
each of these two components, the points associated with threshold, target and
maximum achievement and their corresponding payout percentages are as follows:

      Threshold                    3 points       30% of target
      Target                       6 points       100% of target
      Maximum                      10 points      200% of target

<PAGE>

Payouts for point totals between threshold and target, or between target and
maximum, will be interpolated on a straight-line basis.  Fractions of points
will be counted.

A description of the Market Development and System Development components in
this Plan appears in Sections VIII and IX.

VIII. FITL MARKET DEVELOPMENT COMPONENT

Points for this component are awarded for accounts which are signed up and/or
"turned up" (equipment connected and operational) during FY 1993, and for which
general product approval is obtained during FY 1993.

For purposes of this Plan, accounts are designated as either "major" or "other."
Major accounts are limited to the following 13 organizations:

      GTE
      United Telephone System
      Pentagon

For each major account that is signed up within FY 1993 for a lab trial, field
trial, or first office application (FOA), 1 point will be awarded.  For an
account to be considered signed up, the following documentation must exist:

      Lab trial          Formal letter of intent

                           on the account
      FOA                Purchase order

Although the account must be signed up during FY 1993 for the above 1 point to
be awarded, the actual lab trial,  field trial, and/or FOA does not have to
occur during FY 1993.

For each major account that is successfully "turned up" in FY 1993, 2 additional
points will be awarded for a successful lab trial.  If a field trial and/or FOA
is successfully completed, 3 points will be awarded.  The maximum number of
points per major account for this turn-up phase is 3 points.  The success of any
such turn-up operation must be documented in writing by the Manager of Technical
Support - Customer Services Division.

For each major account for whom general product approval is obtained during FY
1993, 1 additional point will be awarded.  General product approval must be
confirmed by written notification of Approved Supplier status or similar
documentation from the account.

A maximum of 5 points will be awarded for any one major account.

For accounts other than those identified as major, point credit will be one-half
of the major accounts.  A MAXIMUM OF TWO POINTS MAY BE AWARDED FOR ALL MARKET
DEVELOPMENT ACTIVITIES FOR THOSE ACCOUNTS THAT ARE NOT CLASSIFIED AS A MAJOR
ACCOUNT.

</TABLE>

The above points apply to a full FITL system as specified on the attached
"Addendum 1" based on the System Engineering Specification.  The points do not
apply to any special partially operational systems.  However, in the event that
trial of a partial system leads to additional trials of or approval for a full
system during FY 1993, the above point schedule will be applied to that account.

In the event that an account is signed up during FY 1993 but subsequently during
the Fiscal Year cancels plans to turn the system up, the sign-up point will not
be awarded for that account.

IX.   FITL SYSTEM DEVELOPMENT COMPONENT

Points for this component are awarded for achieving any or all of 4 technical
hurdles or milestones during FY 1993 based on the Type A ONU system:

<TABLE>
<CAPTION>

      MILESTONE                                             DEADLINE        POINTS

      Software System Design Verification Testing           7/31/93         1.5 points
      ("DVT") is completed per written plan

      Hardware B-Release is ready,                          9/30/93        1.5 points
      including preparation of all drawings
      and bills-of-material


      System Software B-Release is ready,                   9/30/93        1.5 points
      including preparation of all drawings
      or other documentation and bill-of-material

</TABLE>

For purposes of this Plan, DVT will be considered completed when all tests and
steps have been executed according to the written DVT plan and a complete
listing of all problems identified during the testing phase has been prepared.

In the event that any of the above four milestones is achieved ahead of
schedule, an additional 0.05 point per standard business week day will be
awarded for that milestone, i.e., added to the original 1.5 points.  Conversely,
in the event that any of the above 4 milestones is behind schedule, 0.025 points
per standard business week day up to and including October 31, 1993 will be
subtracted for that milestone, i.e., subtracted from the original 1.5 points.
Zero points will be awarded for any milestone that is not achieved by October
31, 1993.  However, the Chief Executive Officer of the Company may at his
discretion authorize milestone deadline changes for the purpose of this Plan if
they are the result of customer-driven product development modifications and
constitute a strategic redirection in product development.  Any such changes
must be authorized prior to the occurrence of the new milestone deadlines.

<PAGE>

In addition to the points awarded for the above 4 milestones, 1 point may be
awarded for each major new product development successfully achieved to customer
evaluation during FY 1993 that is beyond the FITL business plan for FY 1993.
The definition of "major new product development successfully achieved to
customer evaluation" will be determined at the end of FY 1993 for purposes of
this Plan at the discretion of the Chief Executive Officer of the Company.

X.    COMPANY PERFORMANCE MINIMUM PAYOUT REQUIREMENTS

No portion of the incentive payout will be made to any participant under this
Plan unless the Company's corporate net profits are in excess of a threshold
rate of return on stockholders' equity ("ROE").  This rate has been established
at 10%, after tax, based on stockholders' equity at the beginning of the Fiscal
Year.

XI.   CALCULATION OF PAYMENTS

A.    DETERMINATION OF ACHIEVEMENT AGAINST GOALS AND OBLIGATION TO MAKE
      PAYMENTS.  The obligation to make payments under the Plan will be
      determined by achievement of Corporate and Business Unit goals determined
      by the Board of Directors.

B.    CALCULATION OF INDIVIDUAL PAYMENTS UNDER THIS PLAN IS A FUNCTION OF:

1.    Target incentive opportunity - expressed as a percentage of an
      individual's FY 1993 earnings.  The target % for each participant is
      designated on the "Participant Form".

2.    Participant's 1993 fiscal year base salary earnings

3.    Corporate and FITL performance against the established goals

4.    Individual performance may or may not be used to adjust incentive awards.
      An individual award can be factored plus or minus 50% in increments of 1%
      to account for individual performance.

C.    LIMITATION OF RIGHT PRIOR TO RECEIPT OF PAYMENT.  No participant entitled
      to receive payment under the calculation determined by this Section VII
      and VIII will have any right to pledge, assign, or otherwise dispose of
      any unpaid portion of such payment.

XII.  SAMPLE INCENTIVE CALCULATION

To illustrate how incentive awards are calculated, assume a Plan participant has
a target payout of 11% of base salary earnings of $60,000, or $6,600.

For the CORPORATE OPERATING INCOME GOAL, assume that the Company achieved its
target operating income level.

For the FITL MARKET DEVELOPMENT COMPONENT, assume that:

- -     One major account was signed up in FY 1993 but did not complete any trials
      during the fiscal year.  Only 1 point would be awarded.

- -     A second major account signed up and completed a field trial and FOA
      during FY 1993, plus gave general product approval during FY 1993.  One
      point would be awarded for being signed up, plus 3 points for the FOA,
      plus 1 point for general product approval, for a total of 5 points.

- -     One other account (non-major) was signed up for 0.5 point.

A total of 6.5 points would be achieved for this component.

<PAGE>

For the FITL SYSTEM DEVELOPMENT COMPONENT, assume that:

- -     Hardware DVT was completed on 7/31/93, so 1.5 points would be awarded.

- -     System Software DVT was completed on 8/14/93 (10 days late).  One-quarter
      of a point or 0.25 (0.025 x 10) would be subtracted from the target of 1.5
      points for a final point value of 1.25 points.

- -     Hardware B-release was completed 5 days ahead of schedule.  One-quarter of
      a point or 0.25 (0.05 x 5) would be added to the target of 1.5 points for
      a final point value of 1.75 points.

- -     System Software B-release was completed on 9/30/93, so 1.5 points would be
      awarded.

A total of 6 points would be awarded for this component.

The following calculations illustrate how the incentive award would be
determined:

achievement) +
($60,000 x 11% Target x 40% FITL System Development weight x 100% achievement) =

                                        $6,930.00

XIII. EFFECT OF CHANGE IN EMPLOYMENT STATUS

VOLUNTARY RESIGNATION:  A participant who voluntarily resigns full-time
employment prior to the end of the Fiscal Year will relinquish all rights to any
payment under the Plan.

CHANGE BASED UPON UNSATISFACTORY JOB PERFORMANCE:  A participant who is
involuntarily terminated or transferred to a non-eligible position for reasons
of unsatisfactory job performance will relinquish all rights to any payment
under this Plan.

CHANGE BASED UPON JOB ELIMINATION:  Subject to the approval of the Committee, a
participant who is involuntarily terminated or transferred to a non-eligible
position because of a job elimination may retain the right to a pro-rata payment
based upon the time served in the eligible position during the Fiscal Year.


CHANGE BASED UPON A PROMOTION/DEMOTION:  A current participant who is promoted
or demoted from an incentive eligible position to another incentive eligible
position during the Fiscal Year will have a pro-rata calculation of payment
based upon the time served in each position during the Fiscal Year.

CHANGE BASED UPON TRANSFER BETWEEN CORPORATE AND BUSINESS UNIT PARTICIPANT
CATEGORIES:  A current participant who transfers between the Corporate staff and
FITL Business Unit or between different Business Units with different goals
during FY 1993 will have a pro-rata calculation based on the goals and length of
time spent in the respective participant categories.

VI.  PLAN GOALS

The Plan reinforces the annual financial goals which support ADC's long-term
strategic plans.  The FY 1993 goal categories and weights are as follows:

<TABLE>
   <S>                                                    <C>
     Domestic Revenue                                       50%

     Corporate Operating Income                             30%

   * Corporate Customer Service/Inventory Turn
     Management                                             20%

        TOTAL                                              100%

<FN>
*  CORPORATE CUSTOMER SERVICE/INVENTORY TURN MANAGEMENT goals measure the
company's ability to deliver products to meet customer's request dates while
also effectively managing inventories.  Customer service/inventory turn
management is measured by average inventory turns (the direct cost of goods sold
divided by average direct inventory cost) and by shipping performance (relative
to meeting customer request dates).  A single numerical representation of
customer service/inventory management is derived by  multiplying the average
inventory turn by the percentage of customer request dates met by ADC.

</TABLE>

     For example, if ADC's average annual inventory turns is 3.4 and the
percentage of customer request dates met is 78%, the result is a customer
service/inventory turn management achievement of 2.65.

<TABLE>

                    <S>                            <C>
                    Average inventory turns        3.4
                    % customer request dates met   .78
                                                  ----
                    Result                        2.65
</TABLE>

VII. COMPANY PERFORMANCE MINIMUM PAYOUT REQUIREMENTS

The following minimum Company performance goals must be met to assure protection
of shareholder interest before an incentive payout can be generated.

A.   Incentive payments will be made only if net profits are in excess of a
     threshold rate of return on stockholders' equity.  This rate has been
     established at 10%, after tax, based on stockholders' equity at the
     beginning of the fiscal year.

B.   Participants must meet threshold domestic revenue OR corporate operating
     income goals.

VIII.  CALCULATION OF PAYMENTS

A.   DETERMINATION OF ACHIEVEMENT AGAINST GOALS AND OBLIGATION TO MAKE PAYMENTS.
     The obligation to make payments under the Plan will be determined by
     achievement of Corporate and Business Unit goals determined by the Board of
     Directors.

B.   CALCULATION OF INDIVIDUAL PAYMENTS UNDER THIS PLAN IS A FUNCTION OF:

1.   Target incentive opportunity - expressed as a percentage of an individual's
     FY 1993 earnings.  The target % for each participant is designated on the
     "Participant Form".

2.   Participant's 1993 fiscal year base salary earnings

3.   Performance against the established goals


<PAGE>

4.   Individual performance may or may not be used to adjust incentive awards.
     An individual award can be factored plus or minus 50% in increments of 1%
     to account for individual performance.

C.   HOW INDIVIDUAL AWARDS ARE DETERMINED IS SHOWN BY THE FOLLOWING EXAMPLE:
Assume we have a Plan participant with the following facts:

<TABLE>


<S>                                <C>

D.   LIMITATION OF RIGHT PRIOR TO RECEIPT OF PAYMENT.  No participant entitled
     to receive payment under the calculation determined by this Section VII and
     VIII will have any right to pledge, assign, or otherwise dispose of any
     unpaid portion of such payment.

IX.  EFFECT OF CHANGE IN EMPLOYMENT STATUS

A.   VOLUNTARY RESIGNATION.  A participant who voluntarily resigns full-time
     employment prior to the end of the Fiscal year will relinquish all right to
     any payment under the Plan.

B.   CHANGE BASED UPON UNSATISFACTORY JOB PERFORMANCE.  A participant who is
     involuntarily terminated or transferred to a non-eligible position for
     reasons of unsatisfactory job performance will relinquish all right to any
     payment under this plan.

C.   CHANGE BASED UPON JOB ELIMINATION.  Subject to the approval of the
     Committee, a participant who is involuntarily terminated or transferred to
     a non-eligible position because of a job elimination may retain the right
     to a pro-rata payment based upon the time served in the eligible position
     during the fiscal year.

D.   CHANGE BASED UPON A PROMOTION / DEMOTION.  A current participant who is
     promoted or demoted from an incentive eligible position to another
     incentive eligible position during the fiscal year will have a pro rata
     calculation of payment based upon the time served in each position during
     FY 93.

E.   CHANGE BASED UPON TRANSFER BETWEEN DOMESTIC SALES AND OTHER ADC DIVISIONS.
     A current participant who transfers between Corporate and Business Unit or
     between different Business Units with different goals during FY 93 will
     have a pro rata calculation based on the goals and length of time spent in
     the respective participant categories.

X.   AMENDMENT OR TERMINATION OF PLAN

The Board of Directors reserves and retains the right to modify, rescind or
terminate this plan in whole or in part, at its sole discretion, and nothing in
this Plan limits this right in any way or creates any rights in any employee of
future participation in this Plan or any other plan, or constitutes any
guarantee of compensation or employment with ADC.  Further, neither the Board of
Directors nor the Company has any obligation under this Plan or otherwise to
adopt this or any other plan in any future fiscal year.

                       FIBERMUX MANAGEMENT INCENTIVE PLAN
                                FISCAL YEAR 1993


INTRODUCTION

- -     The Board of Directors of Fibermux Corporation has authorized a Management
      Incentive Plan ("The Plan") to be administered by the Company President
      and the Human Resources Department.

- -     The Plan provides you with an opportunity to share in the Financial and
      Objective results achieved by the Company and you.  This document
      describes that opportunity, which becomes effective beginning Fiscal 1993.
      (June 29, 1992 through June 30, 1993)

PLAN SUMMARY

- -     The purpose of the Management Incentive Plan is to provide incentive
      compensation to key employees of Fibermux who are major contributors to
      the revenue growth, profitability, and management of the Company.

- -     Two principles are primary to the Plan design:

      1.   THE PLAN REINFORCES THE ANNUAL FINANCIAL GOALS which are part of our
           long-term plans.  The goals featured in the plan relate to Fibermux'
           revenue and earnings before interest and taxes ("EBIT").

      2.   THE PLAN PLACES EMPHASIS ON INDIVIDUAL PERFORMANCE AND GROUP
           ACHIEVEMENTS as a basis for compensation.  Measurable Performance
           Objectives will be mutually established by each participant and their
           immediate manager.  Accomplishing these objectives will determine the
           amount of incentive payout on the Objectives section of the Plan.  An
           example form for Performance Objectives is included as Attachment E
           to this document.

ELIGIBILITY

- -     Participation in the Plan is determined by position title and job
      responsibility.  Your eligibility is communicated through an Incentive
      Plan Agreement.

- -     No employee, not previously designated as a participant, will be included
      in the Management Incentive Plan after December 31 of the current fiscal
      year.

- -     A participant in the Management Incentive Plan who voluntarily resigns
      full-time employment prior to the end of the fiscal year will not be
      eligible for any payout from the Plan.  Part-time and/or temporary
      employees are not eligible for participation.

                                  FISCAL 1993


- -     Employees participating in a Sales Compensation Plan are not eligible to
      participate in the Management Incentive Plan.


PLAN GUIDELINES

The operation of the Plan can best be explained by considering the following:

1.    WHAT ARE THE INCENTIVE OPPORTUNITIES FOR EACH PERFORMANCE GOAL?

      The incentive opportunity for each performance measure (Financial Goals
      and individual Performance Objectives) will be weighted by the following
      percentages:

<TABLE>
<CAPTION>

                                      Vice President
                                And Assoc. Vice President  Director  Manager
                                -------------------------  --------  -------
      <S>                       <C>                        <C>       <C>
      Financial Goals                    60%                  55%       50%

      Performance Objectives             40%                  45%       50%

</TABLE>

2.    WHAT ARE THE FINANCIAL GOALS AND HOW ARE THEY MEASURED?

      The incentive compensation earned for Financial Goals will be based upon
      the Participants Base Salary, the actual revenue and the actual earnings
      before interest and taxes as a percent ("%") of revenue ("EBIT %") as
      compared to the Companys target revenue and EBIT% set forth in its Annual
      Operating Plan ("AOP") approved by the Fibermux Board of Directors.

      The Company's Fiscal 1993 AOP Financial Goals are:

                    Revenue             $  65,700,000
                    EBIT                $  13,131,000
                    EBIT%                  19.99%

      The incentive compensation earned for a fiscal year shall be determined by
      calculating the percent of plan ("POP") for each of the actual revenue and
      actual EBIT% for such fiscal year.  The POP shall be calculated as
      follows:

      POPR =   Actual Revenue Dollars        POPP =   Actual EBIT%
               ----------------------                 ------------
                AOP Revenue Dollars                    AOP EBIT%

      As used herein, "POPR" means the POP determined for the actual revenue and
      "POPP" means the POP determined for the actual EBIT%.

      The financial goals will be weighted at 75% for EBIT achievement and 25%
      for revenue achievement.



                                      - 2 -

                            MANAGEMENT INCENTIVE PLAN
                                  FISCAL 1993

      No incentive compensation on financial goals will be paid if either the
      actual revenue or the actual EBIT% falls below 80% of the respective AOP
      amount (I.E., the POP is less than 80%).  The maximum POP is 120%.

      The incentive compensation bonus will be based on the participant's base
      salary as of July 1, 1992.  For eligible employees hired after June 29,
      but before December 31, the base salary at their time of hire will be used
      to calculate their pro-rated incentive compensation bonus.


3.    WHAT ARE THE PERFORMANCE OBJECTIVES AND HOW ARE THEY MEASURED?

      Each participant in the Plan will be required to establish three key
      measurable Performance Objectives for each six-month period in Fiscal 1993
      (Attachment E).  The objectives may be set in the following ways:

      -    Three measurable objectives that have a completion date by the end of
      the  six-month period;

      -    Three measurable objectives that will take the entire year to achieve
      but measurable milestones will be achieved at the end of the six-month
      period;

      -    A combination of the above.

      These objectives will be mutually established and agreed upon by the
      participant and their immediate manager.  Objectives must be approved by
      the Department Vice President, and in some cases, the President.
      Participant attainment of these objectives will determine incentive
      payments for this part of the Plan.

      The review of the objective attainment will be assessed by the participant
      and their immediate manager.  The manager will then recommend to the
      Department Vice President, the Director, Human Resources, and President
      the performance appraisal against these objectives and the incentive
      payment on the Objective section of the Plan.

      If a Participant's job title and/or responsibilities change, Fibermux
      reserves the right to change a Participant's objectives.


4.    WHAT IF MY OBJECTIVES CHANGE?

      A participant can change their Performance Objectives up to forty-five
      (45) days into the six (6) month period.  After that time, no changes will
      be accepted.

      If a Participant's objectives change, the new Performance Objectives must
      be approved by the participant's immediate manager, the Department Vice
      President, the Director, Human Resources, and the President.

                                  FISCAL 1993

5.    HOW ARE INDIVIDUAL INCENTIVE PAYMENTS DETERMINED?

      A participant's incentive payment is determined by the following:

      -    The participant's incentive target opportunity.  The target
           opportunity is expressed as a percentage of the participant's base
           salary as of July 1 of the fiscal year and varies by job level.  The
           target percentage for each position will be noted on the Incentive
           Plan Agreement which will be sent to each participant;

      -    How well Fibermux performs against its established annual financial
           goals;

      -    How well participants perform relative to their individual
           Performance Objectives.


6.    WHEN AND HOW ARE INCENTIVE PAYMENTS MADE?

      1.   Financial Goals Payment

           Payment will be made annually, within two and one-half months  after
           the end of the fiscal year.  The calculations of the incentive
           payouts will be made after the company financial results have been
           audited.

      2.   Performance Objectives Payment

           Payment will be made semi-annually.  The first payment will be within
           forty-five days after the first six-month period.  The second payment
           will be made in conjunction with the financial goals payment made
           within two and one-half months after the end of the fiscal year.


The Plan does not constitute or provide any guarantee of employment or
compensation to participants, and Fibermux has no commitment to adopt this
specific Plan in any future fiscal year.  The President and the Board of
Directors of Fibermux will retain full discretion in the administration of the
Plan, and their decisions will be final.

      An individual award can be factored plus or minus 50% in increments of 1%
      to account for individual performance.

C.    HOW INDIVIDUAL AWARDS ARE DETERMINED IS SHOWN BY THE FOLLOWING EXAMPLE:

Assume we have a Plan participant with the following facts:

Grade:                                  38
Target Payout:                          11% of base salary earnings
Base Salary Earnings:                   50,0000

      to receive payment under the calculation determined by this Section VII
      and VIII will have any right to pledge, assign, or otherwise dispose of

IX.   EFFECT OF CHANGE IN EMPLOYMENT STATUS


A.    VOLUNTARY RESIGNATION.  A participant who voluntarily resigns full-time
      employment prior to the end of the Fiscal year will relinquish all right
      to any payment under the Plan.

B.    CHANGE BASED UPON UNSATISFACTORY JOB PERFORMANCE.  A participant who is
      involuntarily terminated or transferred to a non-eligible position for
      reasons of unsatisfactory job performance will relinquish all right to any
      payment under this plan.

C.    CHANGE BASED UPON JOB ELIMINATION.  Subject to the approval of the
      Committee, a participant who is involuntarily terminated or transferred to
      a non-eligible position because of a job elimination may retain the right
      to a pro-rata payment based upon the time served in the eligible position
      during the fiscal year.

D.    CHANGE BASED UPON A PROMOTION / DEMOTION  A current participant who is
      promoted or demoted from an incentive eligible position to another
      incentive eligible position during the fiscal year will have a pro rata
      calculation of payment based upon the time served in each position during
      FY 93.

E.    CHANGE BASED UPON TRANSFER BETWEEN ADC MINNESOTA AND KENTROX.  A current
      participant who transfers between Corporate and Business Unit or between
      different Business Units with different goals during FY 93 will have a pro
      rata calculation based on the goals and length of time spent in the
      respective participant categories.


X.    AMENDMENT OR TERMINATION OF PLAN

The Board of Directors reserves and retains the right to modify, rescind or
terminate this plan in whole or in part, at its sole discretion, and nothing in
this Plan limits this right in any way or creates any rights in any employee of
future participation in this Plan or any other plan, or constitutes any
guarantee of compensation or employment with ADC.  Further, neither the Board of
Directors nor the Company has any obligation under this Plan or otherwise to
adopt this or any other plan in any future fiscal year.

conditions.

          1.   LEASE OF PREMISES AND DEFINITIONS.

          (a)  Landlord hereby leases to Tenant, and Tenant hereby leases from
Landlord, on an as-is basis except as herein otherwise specifically provided,
that certain building commonly known as 21415 Plummer Street, Los Angeles,
California depicted on the attached EXHIBIT A (hereinafter referred to as the

with, the easements, restrictions and other matters of record and access which
is disclosed by inspection.

          (b)  The term "Property" shall mean that certain real property, of
which the Premises is a part, legally described on the attached Exhibit B, on
which Property are located the Building and the building commonly known as 21605
Plummer Street ("Rockwell Building").

          (c)  The term "Tenant's Proportionate Share" shall mean the percentage
from time to time obtained by dividing the rentable area of the Premises
(including any space added to the Premises as provided in this Lease) by the sum
of the rentable area of the Building and the rentable area of the Rockwell
Building. Such rentable areas shall be initially measured, not later than the
Commencement Date, by Tenant's space planner, at Tenant's expense, in accordance
with the National Standard Method for Measuring Floor Area in Office Buildings,
ANSI Z65.1-1980 ("BOMA Standard"), which space planner shall submit such
measurements to Landlord for Landlord's approval (which approval shall be given
or withheld in writing, shall not be unreasonably withheld and shall be deemed
to be not given if not given or withheld in writing within 10 days after a
written request for such approval has been received by Landlord from Tenant).
If the rentable area of the Building, as so measured and approved, is within 1%
of 97,104 square feet, then the rentable area of the Building shall, for
purposes of this Lease, be deemed to be 97,104 square feet.  If the rentable
area of the Rockwell Building, as so measured and approved, is within 1% of
130,572 square feet, then the rentable area of the Rockwell Building shall, for
purposes of this Lease, be deemed to be 130,572 square feet.  If the Building

altered building(s) to be remeasured by a qualified party in accordance with



<PAGE>

the BOMA Standard, which remeasurements shall be submitted top Tenant for
Tenant's approval (which approval shall be given or withheld in writing, shall
not be unreasonably withheld and shall be deemed to be not given if not given or
withheld in writing within 10 days after a written request for such approval has
been received by Tenant from Landlord).  If the rentable area of the Building or
of the Rockwell Building, as so remeasured and approved, is within 1% of the
actual or deemed rentable area of the Building or Rockwell Building applicable
under this Lease immediately prior to the alteration(s), then the rentable area
of the Building or of the Rockwell Building shall, for the purposes of this
Lease, be deemed to be the actual or deemed rentable area of the Building or of
the Rockwell Building applicable under this Lease immediately prior to the
alteration(s).  If less than all of the Rockwell Building is added to the
Premises pursuant to this Lease, Landlord shall, at Landlord's expense, cause
the added space to be measured by a qualified party in accordance with the BOMA
Standard, which measurement shall be submitted to Tenant for Tenant's approval
(which approval shall be given or withheld in writing, shall not be unreasonably
withheld and shall be deemed to be not given if not given or withheld in writing
within 10 days after a written request for such approval has been received by
Tenant from Landlord). The parties to this Lease shall execute an amendment to
this Lease establishing Tenant's Proportionate Share and the rentable areas of
the Premises, the Building and/or the Rockwell Building, if necessary, at the
time of the initial measurement and each subsequent measurement.

          (d)  "Appraisal" shall mean an appraisal of Market Rent (as defined in
this Lease below) conducted in accordance with the procedures set forth in
attached Exhibit D.

          (e)  "Market Rent" shall mean the annual Base Rent (expressed as an

the commencement date of the term in question if it were to lease the space in
question pursuant to the terms of this Lease (except to the extent that this
Lease is inconsistent with the assumptions and requirements set forth below) to
a tenant with a credit standing comparable to that of Tenant; with parking
rights as provided in this Lease; for a term equal to the period in question;
with a commencement date of the date in question; and in an "as is" condition,
except to the extent that Landlord is required under this Lease to make
improvements.  In determining the "Market Rent", current conditions in the
marketplace for comparable transactions shall be considered, including without
limitation, tenant inducements, if and to the extent then a part of market
conditions, such as, but not limited to, buildout allowances or work, free rent,
financial inducements and credits for moving expenses.  For purposes of
determining Market Rent it shall be assumed that Landlord and Tenant are each
ready, willing and able to enter into such a lease but are under no compulsion
to do so.

          (f)  The term "Consumer Price Index" shall mean the Consumer Price
Index issued by the U.S. Department of Labor, Bureau of Labor
Statistics for Urban Wage Earners and Clerical Workers, U.S. City Average
(1982-1984=100), or its successor index

          2.   TERM.  The initial term of this Lease shall commence on the
Commencement Date (defined below) and shall end on the last day of the 72nd
month thereafter.

          Landlord agrees to use its best efforts (including appropriate legal
proceedings, if reasonably required) to enforce that certain Agreement dated
December 1, 1992, between Landlord and Symbolics, Inc. and that certain letter
agreement dated November 6, 1992, among Landlord, Rockwell International
Corporation ("Rockwell") and Symbolics, Inc., copies of which have been provided
to Tenant.  The Commencement Date shall be the earlier of the date that Tenant
commences business operations in the Premises or the date 180 days following the
date of this Lease, unless Rockwell's vacation of the Premises is delayed beyond
February 28, 1993, in which case the Commencement Date shall be extended by the
number of days (not to exceed 30 days) of such delay.  If such delay exceeds 30
days, Tenant shall have the option to (a) terminate this Lease or (b) continue
with the extension of the Commencement Date for such period (not to exceed 30
days) as Tenant shall determine, such option to be exercised by Tenant by
written notice given to Landlord within 10 days after the expiration of the
initial 30-day period of delay referred to above.  Tenant shall have full
occupancy of the Premises immediately following Rockwell's vacation of the
Premises until the Commencement Date in order to construct the Tenant
Improvements and move into the Building. Such occupancy shall be subject to each
and every provision of this Lease except that Tenant shall not be obligated to
pay any Base Rent or Impositions applicable to the period prior to the
Commencement Date. Upon determination of the Commencement Date, Landlord and
Tenant will execute an agreement confirming the Commencement Date.

          3.   RENT.  Tenant shall pay to Landlord, in advance, on the
Commencement Date and on the 1st day of each calendar month thereafter during
the initial term of this Lease, the following net monthly rental ("Base Rent"),
over and above the other and additional payments to be made by Tenant as
hereinafter provided, as follows:

                                          Base Rent to
       Months                           be paid per month
- ----------------------                  -----------------
<S>                                     <C>
1st month                               $77,000.00
2nd through 5th month                   $        0
6th through 9th month                   $38,500.00
10th through 36th month                 $77,000.00
37th through 72nd month                 $77,000.00, subject to the following
                                                    increase.

</TABLE>
; provided, however, that the Base Rent payable for the first month shall be
reduced by $2,531.50 for each day that Tenant's commencement of business
operations in the Premises is later than the date 150 days after the date of
this Lease (but such reduction shall in no event exceed $77,000). Commencing
with the first day of the 37th month of the initial term hereof, the Base Rent
shall be increased based upon the percentage increase in the Consumer Price
Index, as such Index for the 36th month of the initial term hereof bears to such
Index for the month preceding the first full month of the initial term;
provided, however, that in no event shall the monthly Base Rent commencing on
the 37th month of the initial term be more than $88,550.00 or less than
$83,930.00.

          Notwithstanding the foregoing, if the rentable area of the Premises is
deemed, pursuant to paragraph 1(c) of this Lease, to be an amount other than
97,104 square feet, then Tenant shall pay to Landlord, in advance, on the
Commencement Date and on the 1st day of each month thereafter during the initial
term of this Lease, the following Base Rental, rather than the Base Rental set
forth in the immediately preceding grammatical paragraph:

<TABLE>
<CAPTION>

                                          Base Rent to

- ----------------------                  -----------------
<S>                                     <C>
1st month                               $.793  per rentable square foot
2nd through 5th month                   $   0
6th through 9th month                   $.3965 per rentable square foot
10th through 36th month                 $.793  per rentable square foot
37th through 72nd month                 $.793  per rentable square foot, subject
                                               to the following increase.
</TABLE>

; provided, however, that the Base Rent payable for the first month shall be
reduced by $.02607 per rentable square foot for each day that Tenant's
commencement of business operations in the Premises is later than the date 150
days after the date of this Lease (but such reduction shall in no event exceed
$.793 per rentable square foot for one month). In such case, commencing with the
first day of the 37th month of



                                       - 4 -
<PAGE>

the initial term hereof, the Base Rent shall be increased based upon the
percentage increase in the Consumer Price Index, as such Index for the 36th
month of the initial term hereof bears to such Index for the month preceding the
first full month of the initial term; provided, however, that in no event shall
the monthly Base Rent commencing on the 37th month of the initial term be more
than $.9120 per rentable square foot or less than $.8644 per rentable square
foot.

          The foregoing Base Rent schedules refer to calendar months beginning
with the first full calendar month of the initial term of this Lease.
Accordingly, if the Commencement Date is other than the first day of a calendar
month, the Base Rent for the partial month preceding the first full calendar
month of the initial term of this Lease, which is payable on the Commencement
Date, shall be determinated on a prorated basis, using for such determination
the monthly Base Rent stated above with respect to the 10th calendar month.

          The term "rent" as used in this Lease shall refer collectively to the
Base Rent and to all additional rent, charges and other sums payable hereunder.
Tenant hereby acknowledges that late payment by Tenant to Landlord of rent and
other sums due hereunder after the expiration of any applicable grace period
will cause Landlord to incur costs not contemplated by this Lease, the exact
amount of which will be difficult to ascertain.  Such costs include, but are not
limited to, processing and accounting charges, and late charges which may be
imposed on Landlord by the terms of any trust deed covering the Premises.
ACCORDINGLY, IF ANY INSTALLMENT OF RENT OR ANY OTHER SUMS DUE FROM TENANT SHALL
NOT BE RECEIVED BY LANDLORD WHEN DUE OR IF A GRACE PERIOD IS APPLICABLE, PRIOR
TO THE EXPIRATION OF THE GRACE PERIOD, TENANT SHALL PAY TO LANDLORD A LATE
CHARGE EQUAL TO 5% OF SUCH OVERDUE AMOUNT.  THE PARTIES HEREBY AGREE THAT SUCH
LATE CHARGE REPRESENTS A FAIR AND REASONABLE ESTIMATE OF THE COSTS LANDLORD WILL
INCUR BY REASON OF LATE PAYMENT BY TENANT BASED UPON THE CIRCUMSTANCES EXISTING
AS OF THE DATE OF THIS LEASE. [INITIALS OF THE PARTIES AS TO THE TWO SENTENCES
SHOWN IN BOLD: _______________________]

          4.   PARKING.  Tenant shall have the right to use 215 parking spaces
on the Property in the Fibermux Area shown on the attached EXHIBIT A ("Fibermux
Area").  Landlord, using reasonable efforts, shall also attempt to obtain
parking for an additional 173 vehicles (the "Additional Parking Spaces").  Any
Additional Parking Spaces not provided within the Fibermux Area shall be
provided first (a) in the Rockwell Area shown on the attached EXHIBIT A
("Rockwell Area"), and (b) then at 21540 Plummer Street (across the street from
the Premises).  All Additional Parking Spaces to be provided by Landlord shall
meet applicable governmental requirements and shall be approximately the same
size as the existing spaces in the Fibermux and Rockwell Areas shown on the
attached EXHIBIT A.  All parking spaces to be provided by Landlord in the
Fibermux Area and the other areas shall be identified and controlled in a manner
reasonably acceptable to Landlord and Tenant. Such parking spaces shall also be
non-tandem and shall be on the basis of the



                                       - 5 -
<PAGE>

existing stall striping; provided, however, that Tenant may, in its sole
discretion, elect to permit Landlord to provide some or all of the Additional
Parking Spaces on a tandem basis; and provided further, however, that Tenant may
restripe the delivery area of the Premises and/or the parking spaces on any
parking area provided by Landlord for Tenant's use, at Tenant's sole expense,
and in such event the number of additional parking spaces yielded by such areas
after such restriping by Tenant shall be deemed to be "Additional Parking
Spaces" for purposes of this Lease.

          For each month after the Commencement Date and continuing through the
initial term of this Lease, so long as 173 Additional Parking Spaces are not so
provided, Landlord shall pay to Tenant on the first day of each such month a sum
equal to $45.00 times the number of such Additional Parking Spaces not so
provided for that month; provided, however, that for the first seven months
following the Commencement Date, the sum due from Landlord for each such
Additional Parking Space not provided shall only be $22.50; and provided
further, however, that, if Tenant adds Additional Parking Spaces as a result of
its restriping of the Fibermux Area as provided above, Landlord shall have no
obligation to make such payments with respect to such added spaces from and
after the date that they are added to the Fibermux Area. Tenant shall deduct
such amounts due for each month of the initial Lease term from the monthly
rental payment for such month; provided, however, that, as to the 1st through
5th full calendar months following the Commencement Date, the sums due from
Landlord shall be deducted by Tenant from the payment of Base Rent due for the
6th full calendar month following the Commencement Date (and, if necessary, the
Base Rent payments due in subsequent months) under this Lease.

          From and after the date Tenant has more than 215 parking spaces on the
Property (except to the extent that such excess parking spaces are leased to
Tenant as a result of Tenant's exercise of the Expansion Option), such payments
of $45.00 per month or $22.50 per month, as the case may be, shall cease with
respect to each such space in excess of 215 spaces. For each Additional Parking
Space provided by Landlord in the locations described in subparagraphs (a) and
(b) above after the date of this Lease, the amount otherwise payable by Landlord
hereunder shall be reduced by $30.00 per month for each such Additional Parking
Space so provided.

          Tenant may enter into a lease or leases for parking at other than the
sites described in subparagraphs (a) and (b) above for: those Additional Parking
Spaces which Landlord does not commit by a written notice delivered to Tenant by
February 1, 1993 to provide to Tenant as of the Commencement Date; or any
Additional Parking Spaces that are provided by Landlord at any time during the
initial term of this Lease and are thereafter, during such initial term,
terminated by any landlord(s) thereof.  Landlord shall provide at least 75 days'
prior written notice to Tenant if Landlord will be providing Additional Parking
Spaces after the



                                       - 6 -
<PAGE>

Commencement Date.  Landlord shall provide at least 75 days' prior written
notice to Tenant if Landlord will cease to provide any Additional Parking
Spaces, in which case Tenant shall be entitled to enter into parking leases to
replace such Additional Parking, as provided above.  Notwithstanding the
foregoing, notices from Landlord to Tenant of either the provision or cessation
of Additional Parking Spaces which result from the elimination of any parking
permitted by the City of Los Angeles upon its easement area shall be the 75 days
notice specified above or the number of days of notice of elimination of parking
Landlord receives from the City of Los Angeles, whichever is less. Within ten
(10) days after entering into any parking lease, Tenant shall provide a copy
thereof to Landlord.  If Landlord thereafter provides to Tenant the Additional
Parking Spaces required on either of the sites described in subparagraphs (a) or
(b) above, and Tenant consequently cancels its parking lease(s), Landlord shall,
at Landlord's election made by written notice to Tenant at the time such
Additional Parking Spaces are delivered to Tenant, either reimburse Tenant for
the lease cancellation charge for each such canceled parking space or pay Tenant
$15 per month for the remainder of the initial term of this Lease for each
parking space as to which Landlord has elected not to pay the such cancellation
charge.  Such reimbursement by Landlord to Tenant for lease cancellation charges
shall include Tenant's unamortized costs of improving such parking site, based
on a six-year amortization period.

          Notwithstanding the foregoing provisions of this paragraph 4, if
Rockwell ceases to lease all or any portion of the Rockwell Building, then the
following shall apply:

          (1) If Rockwell at any time no longer leases any space in the Rockwell
Building, then a portion of the parking spaces in the Rockwell Area will be
added, at no cost to Tenant, to the parking spaces already available to Tenant,
which portion shall be determined by adding together the parking spaces then in
the Rockwell Area and the Fibermux Area, dividing such sum by the total rentable
square footage of the Rockwell Building and of the Building, multiplying such
dividend (the "Dividend") by the rentable area of the Building and subtracting
the number of parking spaces in the Fibermux Area from the result.  The
resulting figure will be rounded to the nearest whole number. If Tenant has then
exercised or subsequently exercises the Expansion Option, then another portion
of the parking spaces in the Rockwell Area will be provided to Tenant, at no
cost to Tenant, which portion shall be determined by multiplying the Dividend by
the rentable area of the Expansion Space, the resulting figure to be rounded to
the nearest whole number.

          (2) If Rockwell continues to lease a part of the Rockwell Building,
then a portion of the parking spaces in the Rockwell Area will be added, at no
cost to Tenant, to the parking spaces available to Tenant in the Fibermux Area,
which portion shall be determined as follows:



                                       - 7 -
<PAGE>

               [total parking spaces in the Rockwell Area] - [(total parking
               spaces in the Rockwell Area) x (rentable area of the portion of
               Rockwell Building being leased by Rockwell) divided by rentable
               area of Rockwell Building] - [(total parking spaces on the
               Property) x (rentable area of the portion of the Rockwell
               Building that is not being leased by Rockwell) divided by (total
               rentable area of the Building and the Rockwell Building)],
               rounded to the nearest whole number

                    PLUS, IF TENANT HAS THEN EXERCISED OR
               SUBSEQUENTLY EXERCISES THE EXPANSION OPTION:

               [total parking spaces on the Property x (rentable area of the
               Expansion Space) divided by (total rentable area of the Building
               and the Rockwell Building)], rounded to the nearest whole number

If Rockwell at any time no longer leases any portion of the Rockwell Building,
spaces shall be reallocated as provided in subparagraph (1) above,
notwithstanding that parking spaces may have been previously allocated pursuant
to subparagraph (2) above. The parking spaces made available to Tenant under
subparagraphs (1) and (2) above shall be as close as possible to the space
leased by Tenant and served by such parking. Such added parking spaces shall be
deemed to be Additional Parking Spaces as follows:

               (A)  if Tenant does not elect to lease any Expansion Space
              pursuant to paragraph 55 of this Lease, then all such added
              parking spaces shall be deemed to be Additional Parking Spaces; or

               (B)  if Tenant elects to lease any Expansion Space pursuant to
          paragraph 55 of this Lease, then all such added parking spaces shall
          be deemed to be Additional Parking Spaces, except for the portion of
          such added parking spaces leased to Tenant with respect to the
          Expansion Space as provided above.

If any of the approximately 97 parking spaces in the Rockwell Area that are
located upon an easement granted by the City of Los Angeles are eliminated
because such easement is revoked in whole or in part by the City of Los Angeles,
and if such elimination results in a reduction in the number of parking spaces
that would otherwise have been provided to Tenant as set forth above, then
Landlord shall for the remainder of the initial term of this Lease pay to
Tenant, on the first day of each month during which such parking spaces would
otherwise have been provided to Tenant as set forth above, a sum equal to $45.00
times the number of parking spaces that would otherwise have been provided to
Tenant as set forth above.

          5.   FULL NET LEASE.  Landlord shall receive the rent free and clear
of any and all other impositions, taxes, liens, charges, or expenses of any
nature whatsoever in connection with the ownership and operation of the
Premises, except as herein expressly provided.  In addition to the rent reserved
above, Tenant shall pay to the parties respectively entitled thereto all
impositions, insurance premiums, operating charges, maintenance charges,
construction costs, and any other charges, costs, and expenses that arise or may
be contemplated under any provisions of this Lease during the term hereof. It is
the intention of the parties that this Lease shall not be terminable for any
reason by Tenant, and that Tenant shall in no event be entitled to any set-off
against, abatement of, or reduction in rent payable under this Lease, except as
herein otherwise expressly provided (including, without limitation, the
provisions of paragraph 43 of this Lease).

          6.   USE.  The Premises shall be used and occupied only for the
businesses of testing, assembly, fabrication, warehousing and/or shipping of
electronic components, circuit boards and/or cabinets, and for sales and/or
general office uses related to such types of businesses and for other uses
incidental to the foregoing and for no other use or purpose.

          7.    QUIET ENJOYMENT.  Provided Tenant performs its obligations
hereunder, Tenant shall lawfully and quietly occupy the Premises during the term
of this Lease without hindrance or molestation by Landlord, subject, however, to
the matters herein set forth; provided, however, that, if Tenant is dispossessed
of all or part of the Premises by any party who or which does not claim such
possession through Tenant, Tenant shall be entitled to an equitable abatement of
Base Rent, Impositions, Insurance Costs and other charges under this Lease from
the date of Tenant's dispossession until Tenant's possession is restored and, if
Tenant's possession is not restored within 60 days after Tenant was
dispossessed, Tenant may terminate this lease by written notice given to
Landlord within ten (10) days after the expiration of such 60-day period and
before Tenant's possession is restored.

          8.   PAYMENT OF IMPOSITIONS.  Tenant covenants and agrees to pay to
Landlord Tenant's Proportionate Share (as defined in paragraph 1(c) of this
Lease) of all "Impositions" upon or with respect to the Property.  As used
herein, the term "Impositions" shall include any form of real estate tax,
assessment, license fee, commercial rental tax, improvement bond or bonds, levy,
or other tax, general and special, ordinary and extraordinary, foreseen as well
as unforeseen, of any kind or nature whatsoever, imposed by any authority having
the power to tax (including any city, state, or federal government, or any
school, agricultural, sanitary, water, fire, street, drainage, or other
improvement district thereof ) against any legal or equitable interest of
Landlord in the Premises or in the Property, against Landlord's right to rent or
other income therefrom, and against Landlord's business of leasing the Premises
or the Property; provided, however, that "Impositions" shall not include
inheritance, personal or corporate income, or estate taxes.  The term



                                       - 9 -
<PAGE>

"Impositions" shall also include any tax, fee, levy, assessments, or charge: (a)
in substitution of, partially or totally, any of the above-listed Impositions,
or (b) that is imposed by reason of this transaction, any modifications or
changes hereto, or any transfers hereof. Except as otherwise provided in this
Lease, all such payments shall be made at least fifteen (15) days prior to the
delinquency date. Tenant shall have the right to contest Impositions if there
are reasonable grounds to do so or, if Tenant may not legally do so, to cause
Landlord to do so at Tenant's expense.

          9.   PERSONAL PROPERTY TAXES.  Tenant shall pay prior to delinquency
all taxes assessed against and levied upon trade fixtures, furnishings,
equipment, and all other personal property of Tenant contained in the Premises
or elsewhere.

          10.  UTILITIES.  Tenant shall pay all utility deposits and fees, and
all monthly service charges for heat, water, gas, electricity, sewer service,
elevator (if there be any) and cleaning service, telephone service, and any
other utilities or services whatsoever furnished to the Premises during the term
of this Lease.

          11.  PROPERTY INSURANCE.  Landlord shall procure and maintain
throughout the terms of this Lease all-risk property and liability insurance
insuring the Property (including improvements and betterments, boilers and
machinery owned by Landlord, but excluding all equipment, trade fixtures,
inventory, machinery and other personal property of the Tenant); provided,
however, that Tenant shall maintain builder's risk insurance reasonably
satisfactory to Landlord effective from the commencement of construction of the
Tenant Improvements until the Commencement Date and Landlord's all-risk
insurance shall insure the Tenant Improvements from and after the Commencement
Date. Landlord's all-risk insurance shall insure the Property against risk of
direct physical loss (including loss caused by the perils of earthquake and, if
the Property is in an officially designated flood hazardous area, flood).
Landlord's insurance shall be in an amount equal to the actual replacement cost
of the Property (exclusive of foundations and excavations) without deduction for
physical depreciation, without a coinsurance clause and with a deductible not in
excess of $50,000.  The property insurance carrier shall have an A. M. Best
Company rating of A:VII or better.  Tenant agrees not to do, or fail to do,
anything which will violate the reasonable and customary terms of any such
insurance to the extent such terms are set forth in policies, copies of which
are delivered to Tenant, or otherwise disclosed to Tenant, increase the cost of
such insurance beyond a reasonable level (unless Tenant agrees to pay such
increase) or prevent Landlord from procuring policies reasonably satisfactory to
Landlord. Within ten days of billing by Landlord, Tenant will reimburse Landlord
for Tenant's Proportionate Share of the lesser of (a) all costs of such property
insurance carried by Landlord with respect to the Property, and (b) all costs
which would have been charged by an identically rated carrier (other than
Landlord's carrier) for the same coverage ("Insurance Costs"). Certificates
evidencing all such insurance coverages shall be delivered to Tenant by the date
of this Lease.  Such certificates of insurance



                                       - 10 -
<PAGE>

will provide for thirty (30) days advance notice to Tenant and Landlord in the
event of cancellation or nonrenewal of such insurance.

          12.  OTHER INSURANCE.  Tenant agrees to maintain in full force and
from the Date of this Lease and in effect at all times during the term of this
Lease, at no expense to Landlord, for the protection of Tenant and Landlord, as
their interest may appear, policies of insurance issued by a responsible carrier
or carriers reasonably acceptable to Landlord which afford the following

               (a)  Worker's Compensation - Statutory limits;

               (b)  Employer's liability - Not less than:

                    Bodily Injury by Disease - $250,000 each employee; and

               (c)  Commercial General Liability Insurance on a coverage form at
least as broad as the most recent edition of Commercial General Liability

the Landlord as Additional Insured using an endorsement form at least as broad
as the most recent edition of Additional Insured-Managers or Lessors of Premises

The limits of such insurance shall be no less than:

</TABLE>

Such Commercial General Liability Insurance shall cover Bodily Injury, Personal
Injury and Property Damage Liability occasioned by or arising out of or in
connection with the use, operation and occupancy of the Premises. Such
Commercial General Liability Insurance policy must cover events that occur
during the policy period regardless of when the claim is made.  Such insurance
shall be primary insurance to any other insurance that may be available to
Landlord.  Any other insurance available to Landlord shall be non-contributing
with and excess to this insurance.



                                       - 11 -
<PAGE>

          Certificates evidencing all such insurance coverages shall be
delivered to Landlord by the date of this Lease.  Such certificates of insurance
will provide for thirty (30) days advance notice to Tenant and Landlord in the
event of cancellation or nonrenewal of such insurance.

          13.  LOSS PAYABLE REQUIREMENTS.  All policies of insurance required
hereunder shall provide that the proceeds thereof shall be payable to Tenant and
Landlord, as their respective interests may appear, and, if Landlord so elects,
the policies referenced in paragraph 11 may be payable also to the holder of any
mortgage or deed of trust on the Premises as the interest of such holder may
appear, pursuant to a standard mortgagee clause or a loss payable clause.

          14.  WAIVER OF CLAIMS.  Each party to this Lease hereby releases the
other from any and all claims, and waives its entire right of recovery against
the other, for loss or damage arising out of or incident to the perils insured
against under the policies specified in paragraphs 11 and 12 above to the extent
such loss or damage is insured against under such policies, whether due to the
negligence of such parties or the agents, employees, contractors, or invitees of
either of them. Tenant also waives all claims against Landlord with respect to
Tenant's personal property in the Premises.

          15.  LANDLORD'S RIGHT TO PERFORM TENANT'S COVENANTS. Tenant agrees
that, if Tenant shall at any time fail to make any payment or perform any other
act to be made or performed by it under this Lease, Landlord may, but shall not
be obligated to, make such payment or perform such other act to the extent
Landlord may deem desirable, with full rights of offset, and without waiving or
releasing Tenant from any obligation under this Lease.  All sums so paid by
Landlord and all expenses paid in connection therewith, including without
limitation attorneys' fees, together with interest thereon at the Default
Interest Rate (defined in the paragraph of this Lease entitled "Miscellaneous")
from the date of such payment, shall be paid by Tenant to Landlord on demand.

          16.  MAINTENANCE AND REPAIR.  Except as otherwise set forth in this
Lease, Tenant shall, at Tenant's sole cost and expense, keep the entire Premises
(and every part thereof, including, without limitation, the roof membrane)
secure, clean and in good order, condition, and repair, and shall make promptly
all necessary repairs, interior and exterior, ordinary as well as extraordinary,
foreseen as well as unforeseen, casualty and condemnation excepted; provided,
however, that Landlord shall be responsible for maintaining and repairing the
foundation, the structure of the exterior walls and of the roof and the other
structural members of the Building in accordance with prudent property
management standards, unless the need for such maintenance and repair results
from Tenant's failure to satisfy its maintenance and repair obligations with
respect to the remainder of the Premises or (subject to



                                       - 12 -
<PAGE>

the provisions of paragraphs 11 and 14 of this Lease) the negligence or
intentional acts of Tenant, its employees, agents, contractors or invitees.
Tenant shall also, at Tenant's sole cost and expense, keep the entire Fibermux
Area and any portions of the Rockwell Area provided by Landlord to Tenant for
parking pursuant to paragraph 4 of this Lease or any other provision of this
Lease (including, but not limited to, all paving, striping, landscaping and
attendant driveways, entrances, walkways, curbs, gutters, drains and the like)
clean and in good order, condition and repair, and shall make promptly all
necessary repairs, ordinary as well as extraordinary, foreseen as well as
unforeseen.  When used in this paragraph, the term "repair(s)" shall include
alterations, replacements, and renewals.  All repairs shall be equal in quality
and class to the original work.  Landlord shall have no obligation, in any
manner whatsoever, to repair or maintain the Premises, except as specifically
otherwise provided in this Lease.  Landlord may, at its option, perform Tenant's
repair obligations under this Lease at Tenant's expense if Tenant does not do so
within the applicable cure period provided for in this Lease.

          17.  SURRENDER OF PREMISES.  Upon expiration or any sooner termination
of this Lease, Tenant shall surrender to Landlord the entire Premises, together
with all Alterations (as defined in paragraph 25 of this Lease), in the same
condition as when received or installed (unless such Alterations are to be
removed pursuant to paragraph 24 of this Lease), ordinary wear and tear and
casualty and condemnation excepted, and clean and free of debris and free of any
liens created or suffered to be created by Tenant and (b) Tenant shall properly
remove from the Premises all Hazardous Materials for which it has responsibility
under this Lease. Tenant may, and upon Landlord's request shall, remove any
Trade Fixtures or personal property belonging to Tenant, provided that Tenant
shall perform prior to expiration of the term of this Lease all restoration made
necessary by such removal. Landlord may, at Tenant's expense, retain or dispose
of in any manner any Trade Fixtures or personal property of Tenant that Tenant
does not remove from the Premises upon expiration or termination of the term of
this Lease, in which case title thereto shall vest in Landlord. The term "Trade
Fixtures" as used herein shall mean all fixtures, equipment, and personal
property owned by Tenant and used in connection with the operation of any
business on the Premises, whether or not affixed to the Premises.

          18.  SERVICE CONTRACTS.  Tenant shall, at Tenant's sole cost and
expense, either (a) enter into a regularly scheduled preventive
maintenance/service contract with a maintenance contractor for servicing all hot
water, heating, and air conditioning systems, elevators (if there be any) and
building equipment within the Premises or (b) provide similar services through
the use of its own qualified employees.  The maintenance contractor and the
contract, or the employees of Tenant, as the case may be, shall be subject to
the approval of Landlord (which approval shall be given or withheld in writing,
shall not be unreasonably withheld and shall be deemed to be not given if not
given or withheld in writing within 10



                                       - 13 -
<PAGE>

days after a written request for such approval has been received by Landlord
from Tenant).  The contract or employee-provided services shall include all
services suggested by the equipment manufacturers and shall become effective,
and a copy thereof shall be delivered to Landlord, within thirty (30) days of
the date Tenant takes possession of the Premises. Landlord shall deliver to
Tenant the service manuals for the items to be serviced as provided in this
paragraph and shall deliver and assign to Tenant all warranties covering such
items.

          19.  WASTE.  Tenant shall not do or suffer any waste or damage,
disfigurement, or injury to the Premises or permit or suffer any overloading of
the floors of the Premises.

          20.  ADA.  During the construction of the Tenant Improvements
specified in paragraph 53 of this Lease, Tenant shall also alter and renovate
the Premises to meet the standards established under the provisions of the
Americans With Disabilities Act ("ADA"), and, for such alterations and
additions, Landlord will pay Tenant the sum of $38,000.00 ("ADA Payment"),
regardless of the actual cost of such alterations and renovations. During the
full term of this Lease, Tenant shall also promptly, at its expense (except for
the ADA Payment), comply with the requirements of the ADA applicable to the
Premises, to the construction of the Tenant Improvements, to all other
alterations of the Premises by Tenant and to Tenant's use of the Premises.

          21.  WAIVER OF REPAIR AND DEDUCT.  Tenant hereby waives any and all
rights it may have to make repairs at Landlord's expense or in lieu thereof to
vacate the Premises as provided in California Civil Code Section 1942 or any
other law, statute, or ordinance now or hereafter in effect; provided, however,
that such waiver does not constitute a waiver of any of Tenant's specific
self-help or setoff rights expressly set forth in this Lease.

          22.  COMPLIANCE WITH LAWS.  Tenant shall, at Tenant's sole cost and
expense, comply promptly with all laws, ordinances, orders, regulations, and
requirements of all federal, state, and local governmental agencies, and with
the reasonable recommendations of any insurer under any policies required under
this Lease, that may be applicable to the Premises or the use thereof; provided,
however, that: (a) Tenant shall not be obligated to make any repairs,
alterations or improvements to the Premises that are required by governmental
authorities pursuant to requirements that were in effect on the date of this
Lease to the extent that the Building was not in compliance with such
requirements on the date of this Lease, except for ADA requirements; and (b)
Tenant shall not be responsible for any matters for which Landlord is
responsible under paragraph 23 of this Lease. Landlord shall be responsible for
the costs of compliance described in subparagraphs (a) and (b) of this paragraph
22.  Tenant shall be obligated to make any repairs, alterations or improvements
to the Premises that are required by governmental



                                       - 14 -
<PAGE>

authorities to comply with requirements enacted after the day of this Lease;
provided, however, that, with respect to such requirements that apply generally
to buildings similar to the Building, (1) Tenant will be obligated to cause such
compliance to occur and to pay the cost of such compliance only to the extent
such the cost of such compliance is equal to or less than $25,000 in any
calendar year and (2) Landlord will be obligated to cause such compliance to
occur and to pay the cost of such compliance only to the extent that the cost of
such compliance is in excess of $25,000 per calendar year. If Landlord pays any
cost under subparagraph (2) of this paragraph 22, then monthly Base Rent shall
be increased thereafter by an amount equal to the monthly amortization of such
cost paid by Landlord, determined using an interest rate equal to the Reference
Rate and a period equal to the manufacturer's estimated useful life of the
improvement, alteration and/or replacement to which such cost relates.

          23.  HAZARDOUS MATERIALS.  Tenant agrees not to cause or permit the
presence, use, generation, release, discharge, storage, disposal, or
transportation of any Hazardous Materials (as defined below) on, under, in,
above, to, or from the Property other than presence, use, storage and
transportation which is both (a) required for and solely incidental to Tenant's
principal use and operation of the Premises, and (b) in strict compliance with
all applicable federal, state, and local laws, regulations, and orders (such
obligations of Tenant being referred to below as "Tenant's Environmental
Obligations"). For the purposes of this Lease the term "Hazardous Materials"
shall refer to any substances, materials, and wastes that are or become
regulated as hazardous or toxic substances under any applicable local, state, or
federal law, regulation, or order ("Environmental Laws"). Tenant shall
indemnify, defend, and hold Landlord harmless from and reimburse Landlord for
any breach of Tenant's Environmental Obligations and all of the following which
may result from such a breach: (1) any loss, cost, expense, claim, or liability
arising out of any investigation, reporting, monitoring, clean-up, containment,
removal, storage, or restoration work required by any applicable federal, state,
or local law, governmental agency, or political subdivision or prudent standards
of real estate ownership and management; and (2) any claims of third parties for
loss, injury, expense, or damage arising out of the presence, release, or
discharge of any Hazardous Materials on, under, in, above, to, or from the
Premises during the term of this Lease.

          Landlord shall indemnify, defend, and hold Tenant harmless from and
reimburse Tenant as to the presence, use, generation, release, discharge,
storage, disposal, or transportation of any Hazardous Materials on, under, in,
above, to, or from the Property prior to the Commencement Date, other than as a
result of the breach of Tenant's Environmental Obligations, and all of the
following which may result therefrom: (A) any loss, cost, expense, claim, or
liability arising out of any investigation, reporting, monitoring, clean-up,
containment, removal, storage, or restoration work required by any applicable
federal, state, or local law (which



                                       - 15 -
<PAGE>

requirements Landlord agrees to satisfy at its sole expense), governmental
agency, or political subdivision or prudent standards of real estate ownership
and management; and (B) any claims of third parties for loss, injury, expense,
or damage arising out of such presence, release, or discharge of any Hazardous
Materials on, under, in, above, to, or from the Premises ("Landlord's
Environmental Indemnity"). Landlord will deliver to Tenant, not later than the
date required by paragraph 59 of this Lease, an irrevocable Standby Letter of
Credit ("Letter of Credit") in the initial amount of $2,000,000, issued to
Tenant (but not its assigns) by The Development Bank of Singapore Ltd. (New York
Agency), or another bank of Landlord's selection which is reasonably
satisfactory to Tenant, as security for the performance of Landlord's
Environmental Indemnity.  Such Letter of Credit shall be in substantially the
form attached to this Lease as EXHIBIT E.

          If Landlord defaults at any time during the initial term in the
performance of Landlord's Environmental Indemnity and such default continues
uncured for 30 days after written notice to Landlord, Tenant may draw upon the
Letter of Credit for the full amount paid by Tenant to cure a breach of
Landlord's Environmental Indemnity. Landlord will, at Landlord's expense, keep
the Letter of Credit in effect in the initial amount, less such draws, until the
31st day after the end of the initial term of this Lease (or, if Hazardous
Materials as to which Landlord has indemnified the Tenant pursuant to this Lease
are present or have been used, generated, released, discharged, stored, disposed
of or transported on, in, above, to or from the Property during the initial term
of this Lease, then until such later date as (i) all governmental agencies
having jurisdiction under Environmental Laws make final determinations that all
of the proper actions have been taken or that no actions are required with
respect to such Hazardous Materials and such determinations have been delivered
to Tenant or (ii) a court having jurisdiction over such matters determines that
Landlord has no indemnification responsibilities to Tenant regarding such
Hazardous Materials under the terms of this Lease and all appeals or the time
periods therefor have been exhausted with no change in such determination);
provided, however, that Tenant may waive such requirement at any time by express
written notice.

          Tenant will have the right to draw on the Letter of Credit for the
then full amount of the Letter of Credit if Landlord fails to renew the Letter
of Credit in an amount equal to the original amount thereof, less any amounts
drawn by Tenant to date, and for a period equal to the shorter of (x) 1 year or
more or (y) the remaining portion of the period with respect to which Landlord
is required to maintain the Letter of Credit, if such period can be determined
with certainty, and accomplish such renewal and deliver the renewed Letter of
Credit to Tenant at least 15 days before any expiration date, time being of the
essence. If Tenant draws upon the Letter of Credit because Landlord has failed
to renew the Letter of Credit as required above, Tenant shall hold the proceeds
of such draw in a separate interest-



                                       - 16 -
<PAGE>

bearing account (in Tenant's name) of Tenant's choosing.  The proceeds and
interest in such account shall be paid to Tenant or Landlord as follows:

          (AA)  to Landlord, upon receipt by Tenant of a renewed Letter of
Credit conforming to the requirements of this Lease;

          (BB)  to Tenant, if and to the extent that Tenant would have been
entitled to draw upon the Letter of Credit if it had been renewed; and/or

          (CC)  to Landlord, if and when Landlord is no longer required to
provide the Letter of Credit under the terms of this Lease.

          Tenant agrees that, upon termination of Landlord's obligation to
provide the Letter of Credit, Tenant will surrender the Letter of Credit to
Landlord and will execute all such certificates as Landlord reasonably requests
in connection with the termination of the Letter of Credit.

          Landlord represents and warrants to Tenant that Landlord has no
knowledge of the presence of any Hazardous Materials on, in, or under the
Property in violation of an Environmental Law or of the escape, seepage,
leakage, spillage, discharge, deposit, disposal, emission or release of any
Hazardous Materials on, in, under or from the Premises in violation of an
Environmental Law, except if set forth in (a) that certain Environmental
Assessment for 21605 Plummer Street, Chatsworth (Symbolic II), prepared by
Rockwell, or (b) that certain draft soil and groundwater assessment report for
21415 and 21605 Plummer Street, Chatsworth, California, dated November 23, 1992,
prepared by Groundwater Technology, or (c) that certain letter prepared by
Clayton Environmental Consultants dated November 10, 1992 (collectively, the
"Environmental Assessments"). Tenant represents and warrants to Landlord that
Tenant has no knowledge of the presence of any Hazardous Materials on, in, or
under the Property in violation of an Environmental Law or of the escape,
seepage, leakage, spillage, discharge, deposit, disposal, emission or release of
any Hazardous Materials on, in, under or from the Premises in violation of an
Environmental Law, except if set forth in the Environmental Assessments.

          Tenant agrees to provide to Landlord, within 10 days of receipt, a
copy of any notice regarding violation of any Environmental Law on or about the
Premises arising out of Tenant's operations on the Premises, a copy of any
report required by an Environmental Law regarding violation of the Environmental
Law on or about the Premises arising out of Tenant's operations on the Premises
and a copy of any notice of the emission or release of Hazardous Materials in
violation of an Environmental Law or arising out of Tenant's operations on the
Premises. Each Party agrees to provide to the other, within 10 days of receipt,
a copy of all test reports and correspondence associated with the investigation,
monitoring and



                                       - 17 -
<PAGE>

remediation of soil and groundwater on, in or under the Property and a copy of
any notice regarding the presence of any Hazardous Materials on, in, or under
the Property or the escape, seepage, leakage, spillage, discharge, deposit,
disposal, emission or release of any Hazardous Materials on, in, under or from
the Property in violation of any Environmental Law.

          If  (aa) there is any Hazardous Material on, in, or under the Premises
in violation of an Environmental Law (other than those arising out of a breach
of Tenant's Environmental Obligations) and (bb) as a result thereof, there is,
in the reasonable opinion of Tenant, a danger of harm to the employees or
invitees of Tenant, and a governmental agency having jurisdiction orders Tenant
to vacate the Premises or any affected portion of the Premises and Tenant does
so, then all Base Rent, Impositions, Insurance Costs and other amounts due under
this Lease will abate from the date of such vacation, in proportion to the space
vacated, until the governmental agency which ordered the vacation rescinds or
terminates its order.   If such governmental order is not rescinded or
terminated within ninety (90) days after such vacation of all or part of the
Premises by Tenant, either Landlord or Tenant may, within 30 days after the
expiration of such 90 day period, terminate this Lease by written notice to the
other party.

          Tenant shall have the right during the term of this Lease to conduct
such environmental testing and monitoring of the Premises as Tenant deems
appropriate, including the installation of ground water monitoring wells and/or
such other testing and monitoring as might be included in a Phase II
environmental assessment. Such testing and monitoring shall be conducted in
accordance with applicable laws and regulations and only after not less than
thirty (30) days prior written notice to Landlord.

          The obligations of Landlord and Tenant under this paragraph shall
survive the assignment, termination or cancellation of this Lease.  The rights
of Landlord and Tenant under this paragraph shall be in addition to any other
rights and remedies which Landlord or Tenant may have against the Property, each
other or any other person under any other document or any Environmental Law.

          24.  ALTERATIONS.  Except for non-structural alterations costing less
than $25,000, Tenant shall not alter the Premises or any part of the Property
without the prior written consent of Landlord (which consent shall be given or
withheld in writing, shall not be unreasonably withheld and shall be deemed to
be not given if not given or withheld in writing within 10 days after a written
request for such consent has been received by Landlord from Tenant), which
consent may be granted upon the condition that such alterations be removed (and
the affected portion of the Premises restored), at Tenant's expense, at the
expiration or earlier termination of this Lease. Each written request for such
consent shall contain a paragraph to be



                                       - 18 -
<PAGE>

signed by Landlord indicating whether or not the alteration in question must be
removed by Tenant at the expiration or earlier termination of this Lease.

          25.  PROPERTY OF LANDLORD.   Unless otherwise provided in this Lease,
all repairs, improvements, changes, alterations, and building equipment and
machinery (other than Trade Fixtures, Tenant's telephone switch and equipment,
air compressors and auxiliary air conditioners) made or installed by Tenant
(collectively, "Alterations") shall immediately upon completion or installation
thereof be and become the property of Landlord without payment therefor by
Landlord.

          26.  DAMAGE OR DESTRUCTION.  Subject to the other provisions of this
Lease, if the Premises or any portion thereof becomes damaged or wholly or
partially untenantable because of fire, earthquake, act of God, the elements or
other casualty, Landlord shall repair such damage with and to the extent of the
insurance proceeds made available to Landlord for such purpose.  However, if in
Landlord's opinion such repairs cannot be made within one hundred eighty (180)
days, Landlord shall so notify Tenant in writing within thirty (30) days of the
date of such damage.  In such event, either Tenant or Landlord may terminate
this Lease within thirty (30) days after Landlord's notice.  Termination shall
be effected by written notice delivered to the other party within said thirty
(30) day period.  If this Lease is not so terminated, it shall remain in full
force and effect except that an abatement of Base Rent, Impositions, Insurance
Costs and other amounts due under this Lease shall be allowed Tenant for such
part of the Premises as shall be rendered unusable by Tenant in the conduct of
its business during the time such part is so unusable.

          27.  WAIVER.  Tenant hereby waives California Civil Code Sections
1932, 1933, 1941 and 1942, and the provisions of any other law now or hereafter
in effect that would relieve Tenant from any obligation to pay rent under this
Lease except to the extent expressly provided in this Lease.

          28.  CONDEMNATION.  If the Premises or any portion thereof is taken
under the power of eminent domain (hereinafter referred to as "Condemnation"),
this Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever occurs first. If more than 10% of
the floor area of the Premises is taken by Condemnation, then at Tenant's
option, exercisable only in writing and within ten (10) days after Landlord
shall have given Tenant written notice of such taking (or, in the absence of
such notice, within ten (10) days after the condemning authority shall have
taken possession), and provided that Tenant is not in default under this Lease,
Tenant may terminate this Lease as of the date the condemning authority takes
possession.  If Tenant does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the Basic Rent shall be



                                       - 19 -
<PAGE>

reduced in the proportion that the floor area of the portions of the Premises
taken bears to the total floor area of the Premises.

          29.  CONDEMNATION AWARD.  In the event any portion of the Premises is
taken by Condemnation, Landlord shall be entitled to and shall receive the total
award made in such Condemnation, which award Tenant hereby assigns to Landlord,
except that Tenant shall be entitled to receive such portion of the award as may
be specifically allocated in such proceedings to compensation for Tenant's Trade
Fixtures, for improvements paid for by Tenant and not reimbursed out of the
Tenant Improvement Allowance and for Tenant's relocation expenses.

          30.  RESTORATION.  If less than the entire Premises shall be taken by
Condemnation, and this Lease is not terminated pursuant to paragraph 28, with
the net amount of any award received by Landlord in any proceeding for physical
damage to the Premises after deducting all of Landlord's costs and expenses of
collection, including without limitation attorneys' fees, Landlord shall
promptly restore that portion of the Premises not so taken to a complete
architectural unit.

          31.  TENANT'S WORK.  All work done by Tenant, its agents and
contractors, in or about the Premises or the Property (hereinafter called the
"Work") shall be done in all cases subject to the following conditions, each of
which Tenant covenants to observe and perform:

               (a)  No Work involving any structural change and no Work
involving any alteration, restoration, or rebuilding costing more than $25,000
shall be undertaken until detailed plans and specifications have first been
submitted to and approved in writing by Landlord (which approval shall be given
or withheld in writing, shall not be unreasonably withheld and shall be deemed
to be not given if not given or withheld in writing within 10 days after a
written request for such approval has been received by Landlord from Tenant).

               (b)  No Work involving a cost, as reasonably estimated by Tenant,
of more than $25,000 shall be undertaken except under the supervision of an
architect or engineer approved in writing by Landlord (unless such requirement
is waived by Landlord in writing).

               (c)  All Work shall be (i) commenced only after Landlord has
received 10 days' prior notice of such Work or Landlord has approved such Work
and only after all required local and other governmental permits and
authorizations have been obtained, (ii) done in a good and workmanlike manner,
(iii) performed in compliance with the building and zoning laws and with all
other laws, ordinances, regulations, and requirements of all federal, state, and
local governmental agencies, and in accordance with the recommendations of any
insurer under any policies required by this Lease, and (iv) completed promptly
and



                                       - 20 -
<PAGE>

free of liens.  Approval of any Work by Landlord shall not imply or be construed
to indicate compliance with above requirements.

          32.  MECHANICS' LIENS.  Tenant shall not suffer or permit any
mechanics' or other liens (or claims thereof) to be filed against the Premises
(or Tenant's leasehold interest therein or hereunder) or the Property by reason
of work, labor, services, or materials supplied or claimed to have been supplied
to Tenant or anyone holding the Premises or any part thereof through or under
Tenant; provided, however, that Tenant shall have the right to contest any such
liens so long as Tenant provides Landlord with reasonable security (by bond,
escrow or otherwise) during such contest. Landlord shall have the right at all
reasonable times to post and keep posted on the Premises any notices that
Landlord may deem necessary or advisable for the protection of Landlord, the
Premises and the Property from mechanics' liens.  If any such liens (or claims
thereof) shall at any time be filed against the Premises or the Property, Tenant
shall contest the liens or claims as provided above or shall cause the same to
be discharged of record within forty-five (45) days after the date of filing.

          33.  FINANCIAL STATEMENTS.  Upon the request of Landlord, Tenant shall
provide to Landlord, at no expense to Landlord, copies of the most recent
quarterly and annual financial reports with respect to Tenant as have been made
available by Tenant to its shareholders.

          34.  LANDLORD'S ENTRY.  Tenant agrees to permit Landlord and any
authorized representatives of Landlord, upon reasonable prior notice to Tenant,
to enter the Premises with reasonable frequency during usual business hours, or
at any other time in case of emergency, (a) to inspect (which may include
environmental audits) the Premises and, if Landlord so desires, but without
implying any obligation of Landlord to do so, to make any repairs deemed
necessary or desirable by Landlord and to perform any work in the Premises
deemed necessary by Landlord to comply with any laws or the recommendations of
any insurer, and (b) during the final twelve months of the term of this Lease,
for the purpose of leasing the Premises, during which twelve-month period
Landlord may display on the Premises, in such manner as not to interfere
unreasonably with Tenant's business, usual "For Sale" or "To Let" signs.

          35.  ASSIGNMENT AND SUBLETTING.

               (a)  Tenant shall not, without the prior consent of Landlord
(which consent shall be given or withheld in writing, shall not be unreasonably
withheld and shall be deemed to be not given if not given or withheld in writing
within 10 days after a written request for such consent has been received by
Landlord from Tenant), assign this Lease or any interest herein, sublet the
Premises or any part thereof, or permit the use of the Premises by any party
other than Tenant.  This



                                       - 21 -
<PAGE>

Lease shall not, nor shall any interest herein, be assignable as to the interest
of Tenant by operation of law except as herein otherwise provided. Any of the
foregoing acts without such consent shall be void and shall, at the option of
Landlord, terminate this Lease.  In connection with each consent requested by
Tenant, Tenant shall submit to Landlord the terms of the proposed transaction,
the identity of the parties to the transaction, the proposed documentation for
the transaction, and all other information reasonably requested by Landlord
concerning the proposed transaction and the parties involved.

               (b)  If the Tenant is a privately held corporation, the transfer
(except pursuant to a public offering), assignment, or hypothecation of any
stock or interest in such corporation in excess of fifty percent (50%) in the
aggregate of the voting stock or interest in Tenant shall be deemed an
assignment or transfer within the meaning and provisions of this paragraph. If
Tenant is a publicly held corporation, the public offering or trading of stock
in Tenant shall not be deemed an assignment or transfer within the meaning of
this paragraph.

               (c)  Without limiting the other instances in which it may be
reasonable for Landlord to withhold its consent to an assignment or subletting,
Landlord and Tenant acknowledge that it shall be reasonable for Landlord to
withhold its consent in the following instances:

                    (1)  if at the time consent is requested or at any time
prior to the granting of consent, Tenant is in default under this Lease or would
be in default under this Lease but for the pendency of any grace or cure period
specified in this Lease; or

                    (2)  if the proposed assignee or sublessee is a governmental
agency; or

                    (3)  if, in Landlord's reasonable judgment, the use of the
Premises by the proposed assignee or sublessee would involve occupancy in
violation of this Lease.

               (d)  If at any time during the term of this Lease Tenant desires
to assign its interest in this Lease or sublet all or any part of the Premises,
Tenant shall give notice to Landlord setting forth the terms of the proposed
assignment or subletting ("Tenant's Request").  If the consummation of the
assignment or sublease would cause Tenant to occupy less than 50% of the
rentable area of the Premises, Landlord shall have the option, exercisable by
written notice given to Tenant within thirty (30) days after Tenant's Request is
given ("Landlord's Option Period"), either (1) to consent to the assignment
(which consent shall not be unreasonably withheld and shall be deemed to be not
given if not given or withheld in writing within such 30-day period), in which
event the provisions of subparagraph (g) shall be applicable,



                                       - 22 -
<PAGE>

or to consent to the subletting in which event the provisions of subparagraph
(h) shall be applicable; (2) to become the assignee or sublessee of Tenant
(instead of the entity specified in Tenant's Request) upon the terms set forth
in Tenant's Notice; (3) in the event of (A) a proposed assignment, or (B) a
proposed subletting of the entire Premises, or a portion of the Premises for all
or substantially all of the remainder of the term, to terminate this Lease with
respect to, and to retake possession of, the space in question, together with,
if only a portion of the Premises is involved, such rights of access to and from
such portion as may be reasonably required for its use and enjoyment. If the
foregoing sentence is applicable and Landlord does not exercise one of such
options, or if  Landlord consents or is deemed to consent to the proposed
assignment or sublease, Tenant shall be free for a period of one hundred twenty
(120) days after giving Tenant's Request, or one hundred twenty (120) days after
the date Landlord's consent (if such consent is required) is given to Tenant, or
one hundred twenty (120) days after the expiration of Landlord's Option Period
(if applicable), to assign its entire interest in this Lease or to sublet such
space to the entity specified in Tenant's Request upon the terms set forth
therein or to any third party upon the same terms set forth in Tenant's Request,
subject to obtaining Landlord's prior consent as hereinabove provided.

               (e)  Notwithstanding the provisions of subparagraphs (a) and (b)
above, Tenant may assign this Lease or sublet the Premises or any portion
thereof, with prior notice to Landlord but without the necessity of Landlord's
consent and without extending any option to Landlord pursuant to subparagraph
(d) above, to any corporation which controls, is controlled by or is under
common control with Tenant, or to any corporation resulting from the merger or
consolidation with Tenant ("Affiliate").

               (f)  No sublease, once consented to by Landlord, shall be
modified or terminated by Tenant without Landlord's prior consent (which consent
shall be given or withheld in writing, shall not be unreasonably withheld and
shall be deemed to be not given if not given or withheld in writing within 10
days after a written request for such consent has been received by Landlord from
Tenant).

               (g)  In the case of an assignment to an entity other than
Landlord or an Affiliate, 50% of all sums and other economic consideration
received by Tenant as a result of such assignment shall be paid to Landlord
after first deducting 50% of: (1) the unamortized cost of leasehold improvements
paid for by Tenant, (2) the cost of any concessions and inducements given to the
assignee by Tenant and (3) the cost of any real estate commissions and other
marketing costs incurred by Tenant in connection with such assignment.

               (h)  In the case of a subletting to an entity other than Landlord
or an Affiliate, 50% of all sums and economic consideration received by Tenant
as a result of such subletting shall be paid to Landlord after first deducting
50% of (1) the



                                       - 23 -
<PAGE>

rental due hereunder, prorated to reflect only rental allocable to the sublet
portion of the Premises, (2) the cost of leasehold improvements made to the
sublet portion of the Premises at Tenant's cost, amortized over the term of this
Lease except for leasehold improvements made for the specific benefit of the
sublessee, and the cost of any concessions and inducements given to the
subtenant by Tenant, all of which shall be amortized over the term of the
sublease, and (3) the cost of any real estate commissions and other marketing
costs incurred by Tenant in connection with such subletting, amortized over the
term of the sublease.

               (i)  Regardless of Landlord's consent, no subletting or
assignment (except to Landlord pursuant to the provisions of subparagraph (d)
above) shall release Tenant of Tenant's obligation or alter the primary
liability of Tenant to pay the rent and to perform all other obligations to be
performed by Tenant hereunder.  The acceptance of rent by Landlord from any
other person shall not be deemed to be a waiver by Landlord of any provision
hereof.  Consent to one assignment or subletting shall not be deemed consent to
any subsequent assignment or subletting.  In the event of default by any
assignee of Tenant or any successor of Tenant in the performance of any of the
terms hereof, Landlord may proceed directly against Tenant without the necessity
of exhausting remedies against such assignee or successor.  Landlord may consent
to subsequent assignments or subletting of this Lease or amendments or
modifications to this Lease with assignees of Tenant, without notifying Tenant,
or any successor of Tenant, and without obtaining its or their consent thereto,
and such action shall not relieve Tenant of liability under this Lease.

               (j)  In the event Tenant shall once request the consent of
Landlord to any assignment or subletting, then as to each request for consent to
a further assignment or subletting Tenant shall pay Landlord's then reasonable
and standard processing fee and Landlord's reasonable attorneys' fees incurred
in connection therewith; provided, however, that Tenant shall not be required to
pay Landlord in excess of $500 for Landlord's processing fee or attorney's fees
in connection with any such request.

               (k)  In the event of an assignment of this Lease by Tenant to an
Affiliate, if Tenant returns the Letter of Credit to Landlord and requests
Landlord to do so in writing, Landlord shall promptly cause the Letter of Credit
to be reissued in the name of the assignee as Beneficiary. In the event of any
other assignment of this Lease by Tenant, the Letter of Credit will not be
issued in the name of the assignee and the assignee will have no right to draw
upon or have the benefits of the Letter of Credit.

               (l)  If the initial Tenant assigns this Lease to an Affiliate and
does not request that the Letter of Credit be reissued in the name of the
Affiliate as Beneficiary pursuant to subparagraph 35(k) above, the Letter of
Credit shall be



                                       - 24 -
<PAGE>

maintained by Landlord as required by this Lease for the remainder of the
initial term of this Lease and the initial Tenant shall be entitled to draw upon
the Letter of Credit on its own behalf or on behalf of such Affiliate.

          36.  SUBORDINATION.  At Landlord's option, this Lease shall be
subordinate to any ground lease, mortgage, deed of trust, or any other
hypothecation or security now or hereafter placed upon the Premises and to any
and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements, and extensions thereof.
Notwithstanding such subordination, Tenant's right to a quiet possession of the
Premises shall not be disturbed if Tenant is not in default and so long as
Tenant shall pay the rent and observe and perform all of the provisions of this
Lease, unless this Lease is otherwise terminated pursuant to its terms. If any
mortgagee, trustee, or ground lessor shall elect to have this Lease prior to the
lien of its mortgage, deed of trust, or ground lease, and shall give written
notice thereof to Tenant, this Lease shall be deemed prior to such mortgage,
deed of trust, or ground lease, whether this Lease is dated prior or subsequent
to the date of such mortgage, deed of trust, or ground lease or the date of the
recording thereof.

          37.  ATTORNMENT.  In the event any proceedings are brought for the
foreclosure of, or in the event of exercise of the power of sale under, any
mortgage or deed of trust now or hereafter on the Premises or any part thereof,
Tenant shall, if so requested by the purchaser upon such foreclosure or sale or
the grantee under a deed in lieu of foreclosure, attorn to such purchaser or
grantee and recognize such purchaser or grantee as the Landlord under this
Lease.

          38.  INDEMNIFICATION.  Tenant agrees to indemnify, defend, and save
Landlord harmless from and to reimburse Landlord for any and all claims arising
from (a) the conduct or management of, or any work or thing whatsoever done by
or for Tenant in or about the Premises or the Property during the term of this
Lease, (b) any condition existing during the term of this Lease of (i) the
Premises, (ii) any street, curb, or sidewalk adjoining the Premises, or (iii)
any vaults, passageways, or spaces therein or appurtenant thereto, (c) any
breach or default on the part of Tenant in the performance of any covenant or
agreement on the part of Tenant to be performed pursuant to the terms of this
Lease, (d) any act or negligence of Tenant or any of its agents, contractors,
servants, employees, or licensees occurring about the Premises, (e) any
accident, injury, or damage whatsoever caused to any person, firm, or
corporation occurring during the term of this Lease in or about the Premises or
upon or under the sidewalks or the land adjacent thereto, and (f) any and all
costs, counsel fees, expenses, and liabilities reasonably incurred in connection
with the such claim or action or proceeding brought thereon, except to the
extent that any of the above-described claims arise out of the negligence or
willful misconduct of Landlord, in which case Landlord agrees to indemnify,
defend, and save Tenant harmless from and to reimburse Tenant for any and all
claims arising from such



                                       - 25 -
<PAGE>

negligence or wilful misconduct.  In case any action or proceedings be brought
against an indemnified party by reason of an indemnified claim, the indemnifying
party, upon notice from the indemnified party, covenants to resist or defend
such action or proceeding by counsel satisfactory to the indemnified party.

          39.  ATTORNEYS' FEES.  If any action arising out of this Lease is
brought by either party hereto against the other, then and in that event the
unsuccessful party to such action shall pay to the prevailing party all costs
and expenses, including reasonable attorneys' fees, incurred by such prevailing
party, and if the prevailing party shall recover judgment in such action, such
costs, expenses and attorneys' fees (at trial and on appeal) shall be included
in and as part of such judgment.

          40.  LANDLORD'S CORRECTION OF DEFECTS; REPRESENTATIONS. Tenant shall,
within 30 days after commencing construction of the Tenant Improvements, provide
Landlord with a written list of operating defects, if any, observed by Tenant in
the Building's systems or the portions of the Premises for which Landlord has
maintenance responsibility under paragraph 16 of this Lease. Landlord will, not
later than the Commencement Date (or such earlier date as may be reasonably
required by Tenant in order for Tenant to complete the Tenant Improvements on or
before the Commencement Date),  correct such defects. Except as otherwise
expressly provided in this Lease, Landlord has made no representations of any
nature whatsoever in connection with the condition of the Premises or the
Property or any part thereof, and Landlord shall not be liable for any defects
therein.

          41.  EVENTS OF DEFAULT.  The following events shall be deemed to be
events of default by Tenant under this Lease:

               (a)  The failure of Tenant to pay any installments of Base Rent
or additional rent when due, or any other payment or reimbursement to Landlord
required herein when due, where such failure shall continue for a period of five
(5) days after written notice of such failure.

               (b)  (i)  The application by Tenant for, or Tenant's consent to
the appointment of, a receiver, trustee, or liquidator of Tenant or of all or a
substantial part of Tenant's assets, (ii) the making by Tenant of any general
arrangement or assignment for the benefit of creditors, (iii) Tenant becoming a
"debtor" as defined in 11 U.S.C. Section 101 or any successor statute thereto
(unless, in the case of a petition filed against Tenant, the same is dismissed
within sixty (60) days), (iv) the appointment of a trustee or receiver to take
possession of all or substantially all of Tenant's assets located at the
Premises or of Tenant's interest in this Lease (unless possession is restored to
Tenant within ninety (90) days) or (v) the attachment, execution, or other
judicial seizure of all or substantially all of Tenant's



                                       - 26 -
<PAGE>

assets located at the Premises or of Tenant's interest in this Lease (unless
such seizure is discharged within ninety (90) days).

               (c)  Tenant shall fail to comply with any other term, provision,
or covenant of this Lease, where such failure shall continue for a period of
twenty (20) days after written notice thereof to Tenant, provided, however, that
if such failure cannot reasonably be cured within twenty (20) days, Tenant shall
not be deemed in default with respect to such failure if Tenant commences to
cure such default within said twenty (20) day period and thereafter diligently
and continuously prosecutes such cure to a prompt completion. In the event
Landlord serves Tenant with a "Notice to Perform or Quit" pursuant to applicable
unlawful detainer statutes, such notice shall also constitute the notice
required by this subparagraph, provided that such notice gives Tenant at least
twenty (20) days in which to perform or quit.

          42.  LANDLORD'S REMEDIES.  Upon the occurrence of any event of default
by Tenant, Landlord may, at its option and without any further notice or demand
(in addition to any other rights and remedies under this Lease, at law or in
equity) do any of the following:

               (a)  Landlord shall have the right, so long as such default
continues, to give notice of termination to Tenant.  On the date specified in
such notice (which shall not be less than three (3) days after the giving of
such notice) this Lease shall terminate.

               (b)  In the event of any such termination of this Lease, Landlord
may then or at any time thereafter re-enter the Premises and remove therefrom
all persons and property and again repossess and enjoy the Premises, without
prejudice to any other remedies that Landlord may have by reason of Tenant's
default or of such termination.

               (c)  The amount of damages that Landlord may recover in the event
of such termination shall include, without limitation:  (1) the amount at the
time of award (computed by discounting such amount at the discount rate of the
Federal Reserve Bank of San Francisco at the time of award plus one percent) of
(A) unpaid rent earned at the time of termination, (B) the amount by which the
unpaid rent that would have been earned during the period from termination until
the award exceeds the amount of such rent loss that Tenant proves could have
been reasonably avoided, and (C) the amount by which the unpaid rent for the
balance of the term after the time of award exceeds the amount of such rent loss
that Tenant proves could be reasonably avoided; (2) all legal expenses and other
related costs incurred by Landlord following Tenant's default; (3) all costs
incurred by Landlord in restoring the Premises to good order and condition, or,
to the extent reasonably necessary to accomplish such reletting, in remodeling,
renovating, or otherwise



                                       - 27 -
<PAGE>

preparing the Premises for reletting; and (4) all other costs (including without
limitation any brokerage commissions) incurred by Landlord in
reletting the Premises.

               (d)  Following the termination of this Lease (or upon Tenant's
failure to remove its personal property from the Premises after the expiration
of the term of this Lease), Landlord may remove any and all personal property
located in the Premises and sell or place such property in a public or private
warehouse or elsewhere at the sole cost and expense of Tenant in accordance with
applicable law. Tenant waives all claims for damages that may be caused by
Landlord's removing, storing, or selling the property as herein provided.

               (e)  Landlord shall have the right to cause a receiver to be
appointed in any action against Tenant to take possession of the Premises and to
collect the rents or profits derived therefrom.  The appointment of such
receiver shall not constitute an election on the part of Landlord to terminate
this Lease unless notice of such intention is given to Tenant.

               (f)  Landlord shall have the remedy described in California Civil
Code Section 1951.4 (i.e. Landlord may continue this Lease in effect after
Tenant's abandonment and recover rent as it becomes due, because Tenant has the
right to sublet or assign, subject only to reasonable limitations). Even though
Tenant has breached this Lease and abandoned the Premises, this Lease shall
continue in effect for so long as Landlord does not terminate Tenant's right to
possession, and Landlord may enforce all its rights and remedies under this
Lease, including the right to recover rent in periodic actions as it becomes due
under this Lease.  In such event, Landlord may re-enter the Premises and remove
all persons and property if the Premises have not been vacated, using any
available summary proceedings, without such re-entry or removal being deemed a
termination or acceptance of surrender of this Lease. Landlord may then elect to
relet the Premises for the account of Tenant for a period that may extend beyond
the term hereof, and upon such other terms as Landlord may reasonably deem
appropriate.  Tenant shall reimburse Landlord upon demand for all costs incurred
by Landlord in connection with such reletting, including without limitation
necessary restoration, renovation, or improvement costs, attorneys' fees, and
brokerage commissions.  The proceeds of such reletting shall be applied first to
any sums then due and payable to Landlord from Tenant, including the
reimbursement described above.  The balance, if any, shall be applied to the
payment of future rent as it becomes due hereunder.

          43.  TENANT'S SETOFF RIGHTS.  If (a) Landlord fails to perform any
repair or maintenance obligation of Landlord under this Lease, and fails to cure
such default within 30 days after receipt of notice of such default from Tenant
(or, if Landlord's repair or maintenance obligation cannot be reasonably
performed within 30 days, Landlord fails to commence to perform it within such
30-day period and to



                                       - 28 -

thereafter diligently prosecute it to a prompt conclusion), or (b) Landlord
fails to pay Tenant the Tenant Improvement Allowance when required to do so
under this Lease, and fails to cure such default within one year after receipt
of notice of such default from Tenant, Tenant may cure such default and charge
the costs to Landlord (plus interest on such charges from the date the charges
are incurred by Tenant, at the Default Interest Rate), and may set off such
costs and interest, and/or any portion of the Tenant Improvement Allowance that
has not been made to Tenant by Landlord (plus interest on such portion from the
date it was due to Tenant, at the Default Interest Rate), against installments
of Base Rent due under this Lease; provided, however, that Tenant shall not
set-off against more than 25% of the Base Rent due in any month (but such
limitation shall not apply to the final 6 months of this Lease).  Tenant shall
be permitted to continue to set off against succeeding installments of Base Rent
due under this Lease until the total amount of such costs or payment and
interest thereon have been recovered by Tenant.

          44.  CUMULATIVE REMEDIES.  The specified remedies to which Landlord
may resort under the terms of this Lease are cumulative and are not intended to
be exclusive of any other remedies or means of redress to which Landlord may be
entitled, either at law or in equity, in case of any breach or threatened breach
by Tenant of any covenant, agreement, or condition of this Lease.

          45.  NO WAIVERS.  The failure of Landlord to insist in any one or more
instances upon the strict performance or observance of any of the covenants,
agreements, or conditions of this Lease or to exercise any option herein
contained shall not be construed as a waiver or a relinquishment of future
performance or observance of such covenant, agreement, or condition or exercise
of such option.

          46.  HOLDING OVER.  Tenant covenants that it will vacate the Premises
immediately upon the expiration or sooner termination of this Lease.  If, with
Landlord's consent, Tenant retains possession of the Premises or any part
thereof after the expiration or termination hereof, Tenant shall pay Landlord
200% of the Base Rent due under this Lease immediately before such expiration or
termination, for the time Tenant thus remains in possession.  The provisions of
this paragraph do not exclude Landlord's rights of re-entry or any other right
hereunder, including without limitation the right to refuse 200% Base Rent and
instead to remove Tenant through summary proceedings for holding over beyond the
expiration of the term of this Lease.

          47.  NOTICES.  All notices, demands, and requests that may or are
required to be given by either party to the other shall be in writing and shall
be deemed given when sent by United States Certified Mail, postage prepaid, (a)
if for Tenant, addressed to Tenant (Attn: Chief Financial Officer), prior to
Commencement Date at 9310 Topanga Canyon Boulevard, Chatsworth, California 91311
and after the Commencement Date at the address of the Premises, in either



                                       - 29 -
<PAGE>

case with a copy to ADC Telecommunications, Inc., 12501 Whitewater Drive,
Minnetonka, Minnesota 55343 (Attn: Chief Financial Officer and Attn: General
Counsel),  or at such other address or addresses as Tenant may from time to time
designate by written notice to Landlord, or (b) if for Landlord, addressed to
Landlord, c/o GSIC Realty Corporation, 255 Shoreline Drive, Suite 600, Redwood
City, California 94065 or at such other places as Landlord may from time to time
designate by written notice to Tenant.

          48.  LIMITATION OF LANDLORD'S LIABILITY.  In the event of a sale or
transfer by Landlord of its interest in the Premises or this Lease, such sale or
transfer shall operate to release the transferor from all liability for the
performance of the obligations of Landlord hereunder, expressed or implied, from
and after the date of such transfer, and Tenant agrees thereafter to look solely
to the successor in interest of Landlord in and to this Lease for the
performance of Landlord's obligations hereunder accruing after the date of such
transfer (including the return of the Security Deposit) and thereupon Landlord
shall be discharged from any further liability with respect thereto.

          49.  ESTOPPEL CERTIFICATES.  At any time and from time to time upon
not less than ten (10) days' prior request by Landlord, Tenant agrees to
execute, acknowledge, and deliver to Landlord a statement in writing certifying
(a) that this Lease is unmodified and in full force and effect (or if there have
been modifications, that the same is in full force and effect as modified and
identifying the modifications), (b) the dates to which Base Rent, Impositions,
Insurance Costs and other amounts due under this Lease have been paid, and (c)
whether there is then existing any claim by Tenant of default hereunder by
Landlord and, if so, specifying the nature thereof. It is intended that any such
statement may be relied upon by any person proposing to acquire Landlord's
interest in this Lease or any prospective mortgagee of, or assignee of any
mortgage upon, such interest. At any time and from time to time upon not less
than ten (10) days' prior request by Tenant, Landlord agrees to execute,
acknowledge, and deliver to Tenant a statement in writing certifying (a) that
this Lease is unmodified and in full force and effect (or if there have been
modifications, that the same is in full force and effect as modified and
identifying the modifications), (b) the dates to which Base Rent, Impositions,
Insurance Costs and other amounts due under this Lease have been paid, and (c)
whether there is then existing any claim by Landlord of default hereunder by
Tenant and, if so, specifying the nature thereof. It is intended that any such
statement by Landlord may be relied upon by any person proposing to receive a
mortgage or assignment of Tenant's interest in this Lease or to enter into any
sublease of all or part of the Premises.

          50.  BROKERAGE.  Each party represents and warrants to the other that
it has not dealt with any broker, agent, or other person in connection with this
transaction and that no other broker, agent, or other person brought about this



                                       - 30 -
<PAGE>

transaction through it, other than CB Commercial Real Estate, Mel Goldstein, Bob
Shafer, The Johnston Group and Cal Johnston (whose commissions shall be paid by
Landlord), and each party agrees to indemnify and hold the other party harmless
from and to reimburse the other party for any and all claims by any other
broker, agent, or person claiming a commission or other form of compensation by
virtue of having dealt with it with respect to this leasing transaction.  The
provisions of this paragraph shall survive the termination of this Lease.

          51.  SECURITY DEPOSIT.  Tenant shall, upon execution of this Lease,
deposit with Landlord the sum of $77,000.00 as security for the full and
faithful performance of every provision of this Lease to be performed by Tenant
during the full term of this Lease (the "Security Deposit").  If Tenant defaults
with respect to any provision of this Lease during the term of this Lease and
such default continues beyond the applicable grace period, Landlord may use,
apply, or retain all or any part of the Security Deposit for the payment of Base
Rent or any other sum in default, for the payment of any other amount that
Landlord may spend or become obligated to spend by reason of Tenant's default,
or to compensate Landlord for any other loss, cost, or damage that Landlord may
suffer by reason of Tenant's default. If any portion of the Security Deposit is
so used or applied, Tenant shall, within five (5) days after written demand
therefor, deposit cash with Landlord in an amount sufficient to restore the
Security Deposit to its original amount. Landlord shall not be required to keep
the Security Deposit separate from its general funds and Tenant shall not be
entitled to interest on such deposit. Landlord shall refund the Security Deposit
to Tenant within 10 days after the expiration of the term of this Lease. If (a)
Tenant has reasonable grounds, valid as of a date not more than 30 days prior to
the date that the final full monthly Base Rent payment is due under this Lease,
to believe that the then Landlord is unlikely to be in a financial position to
return the Security Deposit during the required refund period (the then pendency
of bankruptcy proceedings with regard to such Landlord or any general partner
thereof being absolute and unrebuttable evidence of reasonable grounds for such
belief), and/or (b) the then Landlord is a successor to the initial Landlord
under this Lease and has failed to enter into a written agreement running to the
benefit of and enforceable by Tenant whereby the then Landlord unconditionally
assumes all of the Landlord's obligations under this Lease with respect to the
Security Deposit or an original copy of such agreement has not been delivered to
Tenant (provided, however, that the then Landlord may in the alternative provide
Tenant with an opinion of counsel reasonably satisfactory to Tenant that, under
California law then in effect, Tenant shall have the same rights with respect to
the then Landlord without such a written agreement that it would have had if
such a written agreement were executed and delivered to Tenant) and/or (c) if
Landlord is a lender who shall have acquired title to the Premises without
personal obligation to refund the Security Deposit to Tenant within the required
refund period, Tenant shall give notice of such fact(s) to Landlord on or before
the date 15 days prior to the date that the final full monthly Base Rent payment
is due under this Lease. If Landlord



                                       - 31 -
<PAGE>

receives such notice and does not, prior to the date 5 days before the date that
the final full monthly Base Rent payment is due under this Lease, (i) if
subparagraph (a) above applies, provide Tenant with reasonable security for the
performance of Landlord's obligation to refund the Security Deposit and/or (ii)
if subparagraph (b) above applies, provide Tenant with the written agreement or
opinion described in such subparagraph (b) and/or (iii) if subparagraph (c)
above applies, provide to Tenant the lender-Landlord's written personal
commitment to Tenant to refund the Security Deposit during the required refund
period, Tenant may setoff such Security Deposit against the payment of Base Rent
and any other sums due Landlord under this Lease that are due on such payment
date or any subsequent date.

          52.  SIGNAGE.  Tenant shall not place or permit on the exterior or
roof of the Premises or on the balance of the real property constituting the
Premises or on the balance of the Property any sign, advertisement,
illumination, projection, or similar thing (a "Sign"), unless (a) Landlord has
given its prior written consent thereto (which consent shall be given or
withheld in writing, shall not be unreasonably withheld and shall be deemed to
be not given if not given or withheld in writing within 10 days after a written
request for such consent has been received by Landlord from Tenant), and (b)
such Sign complies with applicable law.  Subject to the foregoing, Tenant may
place a monument sign in front of the Premises, Tenant may place a directional
delivery sign at the delivery driveway shown on the attached EXHIBIT A, and may
place a sign or signs on the exterior of the Premises.

          53.  TENANT IMPROVEMENTS.

               (a)  Tenant shall construct the improvements to the Premises
described on the attached EXHIBIT C (collectively, the "Tenant Improvements").
Tenant shall promptly commence the work for Tenant Improvements and shall
diligently pursue such work to completion, as described in subparagraph (e)
below.

               (b)  Tenant shall submit to Landlord complete, finished drawings
and specifications (the "Plans") for the Tenant Improvements.  The Plans shall
be subject to Landlord's approval (which approval shall be given or withheld in
writing, shall not be unreasonably withheld and shall be deemed to be not given
if not given or withheld in writing within 10 days after a written request for
such approval has been received by Landlord from Tenant). Within ten (10)
business days after its receipt of the Plans, Landlord shall notify Tenant of
its approval or disapproval of the Plans, and if Landlord disapproves the Plans,
the revisions that Landlord requires in order to obtain such approval.  Tenant
and Tenant's architect or engineer shall meet with Landlord and its agents
within a reasonable period of time after any request for such meeting by
Landlord to answer questions or provide additional information with respect to
the Plans.  As promptly as reasonably possible thereafter, Tenant shall submit
to Landlord modified Plans incorporating the revisions required by Landlord.
The modified Plans shall be subject to



                                       - 32 -
<PAGE>

Landlord's approval (which approval shall be given or withheld in writing, shall
not be unreasonably withheld and shall be deemed to be not given if not given or
withheld in writing within 10 days after a written request for such approval has
been received by Landlord from Tenant).  The final Plans and specifications
approved by Landlord are hereinafter referred to as the "Final Plans."  If
appropriate, Tenant shall cause two sets of reproducible Final Plans, marked for
pricing and construction to be delivered to Landlord within 5 days after
Landlord's approval of the Final Plans.  Tenant shall engage an architectural
firm, duly licensed in the State of California, for preparation of the Plans and
supervision of the construction of the Tenant Improvements. Such firm shall be
subject to Landlord's approval (which approval shall be given or withheld in
writing, shall not be unreasonably withheld and shall be deemed to be not given
if not given or withheld in writing within 10 days after a written request for
such approval has been received by Landlord from Tenant).  Tenant shall not
commence any work in the Premises until Landlord has finally approved the Plans
(which approval shall be given or withheld in writing, shall not be unreasonably
withheld and shall be deemed to be not given if not given or withheld in writing
within 10 days after a written request for such approval has been received by
Landlord from Tenant).

               (c)  Tenant shall pay all the Tenant Improvement Costs (as
defined below) and, provided there are no events of default by Tenant, Landlord
will provide the Tenant Improvement Allowance specified in subparagraph (e)
below. Tenant Improvement Costs shall include, but not be limited to, the cost
of the work described on the attached EXHIBIT C to the extent included in the
Final Plans, and the following with respect to the Final Plans: hard costs of
construction (including builder's risk insurance and the Performance and Payment
Bonds hereinafter specified), permitting fees and the fees of Tenant's architect
and engineer, and of Tenant's construction manager, if any. Tenant Improvement
Costs shall not include any of Tenant's equipment or other personal property or
trade fixtures.

               (d)  Tenant shall employ a general contractor for the Tenant
Improvements duly licensed in the State of California and approved by Landlord
(which approval shall be given or withheld in writing, shall not be unreasonably
withheld and shall be deemed to be not given if not given or withheld in writing
within 10 days after a written request for such approval has been received by
Landlord from Tenant). Upon request by Landlord, Tenant shall deliver to
Landlord a copy of the construction contract entered into by Tenant and the
general contractor.  Before any work commences, the general contractor shall
obtain and deliver to Landlord Performance and Payment Bonds in form and amount
approved by Landlord (which approval shall be given or withheld in writing,
shall not be unreasonably withheld and shall be deemed to be not given if not
given or withheld in writing within 10 days after a written request for such
approval has been received by Landlord from Tenant). Such Bonds shall name
Landlord as the



                                       - 33 -
<PAGE>

obligee and shall be written by surety companies which have been approved by
Landlord (which approval shall be given or withheld in writing, shall not be
unreasonably withheld and shall be deemed to be not given if not given or
withheld in writing within 10 days after a written request for such approval has
been received by Landlord from Tenant) and are either on the United States
Department of the Treasury's list of sureties acceptable to the United States
Government or have at least a BB+ rating by Bests.  The Tenant Improvements
shall be constructed in a good and workmanlike manner and shall comply with all
laws, codes and ordinances applicable to the Premises.  Not less than five (5)
days prior to the date Tenant desires to commence the Tenant Improvements,
Tenant shall give written notice to Landlord setting forth or accompanied by all
of the following:

                    (i)       A description and schedule for the work to be
performed;

                    (ii)      The names and addresses of all contractors,
subcontractors and material suppliers who have then been engaged to construct or
supply the Tenant Improvements;

                    (iii)     Copies of all licenses and permits which may be
required in connection with the Tenant Improvements and which can then be
obtained; and

                    (iv)      Certificates of builder's risk insurance
reasonably satisfactory to Landlord.

As additional rent under this Lease, Tenant shall make, at its expense, any
repairs to the Premises and any corrections to the Tenant Improvements, the need
for which arise from the actions or omissions of anyone constructing the Tenant
Improvements.  During the progress of the work to be done by Tenant, such work
shall be subject to inspection by representatives of Landlord who shall be
permitted access and the opportunity to inspect, at all reasonable times upon
reasonable advance notice, in compliance with any safety and work rules then
imposed at the Premises by Tenant or its contractors, but this provision shall
not in any way whatsoever create any obligation on Landlord to conduct any such
inspection.

               (e)  Upon completion of the Tenant Improvements in accordance
with the Final Plans and the requirements of the ADA, Landlord shall pay to
Tenant an amount (the "Tenant Improvement Allowance") equal to the sum of (1)
the lesser of the Tenant Improvement Costs or $600,000, plus (2) the ADA
Payment, upon receipt of all of the following: (i) unconditional lien waivers
from all contractors, subcontractors and suppliers of materials and equipment,
(ii) an affidavit executed by the general contractor certifying the cost of the
Tenant Improvements and stating that it has delivered to Landlord lien waivers
from all



                                       - 34 -
<PAGE>

subcontractors and suppliers and that the contractor has paid all debts or
settled all claims for labor and materials in connection with the Tenant
Improvements, (iii) an affidavit executed by Tenant that it accepts and is
satisfied with the Tenant Improvements and that all contractors and suppliers in
connection with the Tenant Improvements have been paid, (iv) a certification of
completion executed by the Tenant's architect confirming that the Tenant
Improvements have been completed in accordance with the Final Plans and that, if
required, a Certificate of Occupancy (temporary or permanent) has been issued
with respect to the Premises by the local authority having jurisdiction thereof,
and (v) if required by Landlord, a complete set of "as-built" plans and
specifications for the Tenant Improvements.  The Tenant Improvements shall be
deemed completed upon satisfaction of all of the foregoing. Tenant's obligation
to pay the rent under this Lease shall not be postponed due to delay of any
nature, however arising, in completion of the Tenant Improvements, except for
delays caused by Landlord's failure to perform its repair and maintenance
obligations under paragraphs 16 and 40 of this Lease, in which case the
Commencement Date shall, at Tenant's option to be exercised by written notice to
Landlord, be extended by the number of days of delay so caused by Landlord.

               (f)  Tenant agrees to expend at least $400,000 in excess of the
Tenant Improvement Allowance for the Tenant Improvements, including costs of
Tenant's internal space planners and internal environmental review.

          54.  OPTIONS TO EXTEND TERM.  Tenant shall have two options
(collectively the "Options" and individually an "Option") to extend the term of
this Lease for two additional consecutive six (6) year periods, the first of
which shall commence on the expiration of the initial term of this Lease (the
"First Renewal Option") and the second of which shall commence six (6) years
thereafter (the "Second Renewal Option"), provided that:

               (a)  The First Renewal Option shall be exercised by written
notice of exercise delivered to Landlord no later than nine (9) months before
the expiration of the initial term of this Lease, and the Second Renewal Option
shall be exercised by written notice of exercise delivered to Landlord no later
than nine (9) months before the expiration of the term of the First Renewal
Option.  If Tenant fails to so exercise the First Renewal Option, both of the
Options shall terminate.  If Tenant so exercises the First Renewal Option but
fails to so exercise the Second Renewal Option, the Second Renewal Option shall
terminate;

               (b)  At the time each Option is exercised and at the commencement
of the term of each Option, this Lease must be in full force and effect and
Tenant must not then be in default under this Lease. The foregoing conditions
are for the benefit of and may be waived by Landlord; and



                                       - 35 -
<PAGE>

               (c)  All of the terms, covenants and conditions of this Lease
shall remain in effect during the term of each Option except that (i) the Base
Rent commencing with the first day of the first month for each month of the
first thirty-six (36) months of the First Renewal Option shall be increased
based upon the percentage increase in the Consumer Price Index as such Index for
the 37th month of the initial term of this Lease bears to such Index for the
last month of the initial term; provided, however, that in no event shall the
Base Rent commencing with the first month of such term be more than 115% or less
than 109% of the Base Rent payable for the last month of the initial term of
this Lease; and (ii) commencing with the first day of the 37th month of the term
of the First Renewal Option, the Base Rent shall be increased based upon the
percentage increase in the Consumer Price Index as such Index for the 36th month
of such term bears to such Index for the last month of the initial term;
provided, however, that in no event shall the Base Rent commencing with the 37th
month of such term be more than 115% or less than 109% of the Base Rent payable
for the 36th month of the term of the First Renewal Option, and (iii) the Base
Rent for each month of the term of the Second Renewal Option shall be the Market
Rent for the Premises for the term of the Second Renewal Option (determined by
Appraisal if the parties cannot agree upon the Market Rent within 30 days after
Tenant's exercise of the Second Renewal Option); except that commencing with the
first day of the 37th month of the term of the Second Renewal Option, the Base
Rent shall be increased based upon the percentage increase in the Consumer Price
Index as such Index for the 36th month of such term bears to such Index for the
last month of the term of the First Renewal Option; provided, however, that in
no event shall the Base Rent commencing with the 37th month of such term be more
than 115% or less than 109% of the Base Rent payable for the 36th month of the
term of the Second Renewal Option.

          55.  EXPANSION SPACE.  Rockwell presently occupies that portion of the
Property commonly known as 21605 Plummer Street (the "Rockwell Building") which
contains approximately 130,572 rentable square feet of space. Rockwell has the
right to park 410 cars in the Rockwell Area. The term of the lease agreement for
the Rockwell Building expires on June 30, 1997, but Rockwell has the option to
cancel on one-year's prior written notice.  If Rockwell cancels its tenancy and
Landlord determines not to grant Rockwell rights to occupy the Rockwell Building
(or any portion thereof in excess of 105,000 square feet of rentable area) on
some basis, then, subject to the terms of this paragraph, Tenant shall have one
option (the "Expansion Option") to add to the Premises demised under this Lease,
the "Expansion Space" which shall be (i) the Rockwell Building, or (ii) a
portion thereof which shall consist of not less than 25,000 rentable square feet
and shall be configured (as mutually agreed upon by Landlord and Tenant in
writing) in such a manner as to meet Tenant's reasonable requirements and
applicable codes and any reasonable objections of Landlord set forth in written
notice to Tenant within ten (10) days after Landlord's receipt of Tenant's
Notice (as hereinafter defined), as follows:



                                       - 36 -
<PAGE>

               (a)  Tenant agrees to accept the Expansion Space in its "as is"
condition on the Availability Date (hereinafter defined) except as in this
paragraph otherwise provided;

               (b)  Landlord shall give Tenant written notice ("Landlord's
Notice") of the date upon which the Expansion Space shall be available (the
"Availability Date") and of the location and size of the Expansion Space. Tenant
shall have one option to have the Expansion Space added to the Premises demised
under this Lease on the Availability Date upon all the terms, covenants and
conditions contained in this Lease except that (i) the Base Rent for the
Expansion Space for the balance of the term of this Lease shall be Market Rent
with an $8.00 per net rentable square foot improvement allowance and without
reduction for the cost of creating all demising walls and related improvements
necessary for the Expansion Space to function separately from the remainder of
the Rockwell Building, which demising walls and related improvements Tenant
shall cause to be constructed and the costs of which shall be paid one-half by
Tenant and one-half by Landlord (which improvement allowance and other Landlord
reimbursements shall be paid to Tenant in accordance with disbursing procedures
similar to those provided for in paragraph 53 of this Lease), (ii) Tenant shall
be permitted to take occupancy of the Expansion Space on the Availability Date
in order to construct improvements therein, subject to each and every provision
of this Lease except that Tenant shall not be obligated to pay Base Rent with
respect to the Expansion Space until the "Rent Start Date" (defined below), and
(iii) the Rent Start Date shall be the 180th day after the Availability Date or
the date Tenant substantially completes its improvements in and occupies the
Expansion Space for business purposes, whichever is the earlier;

               (c)  The Expansion Option shall be exercised, if at all, by
written notice ("Tenant's Notice") of exercise given to Landlord not later than
twenty (20) days after Tenant's receipt of the Landlord's Notice.  If Tenant
fails to so exercise the Expansion Option it shall terminate;

               (d)  If Landlord and Tenant cannot agree upon the determination
of Market Rent on or before the date that Tenant is required to give Landlord
Tenant's Notice, and Tenant nonetheless elects to give Tenant's Notice, the
determination of Market Rent as to such Expansion Space will be submitted to
Appraisal in accordance with attached EXHIBIT D.  If on the date Base Rent as to
such Expansion Space is scheduled to commence pursuant to this Lease the
Appraisal has not been completed, Tenant will pay Base Rent based on Landlord's
reasonable estimate of Market Rent.  Upon determination of Market Rent by
Appraisal, Landlord will pay to Tenant or Tenant will pay to Landlord, as
appropriate, the amount equal to the overpayment or underpayment of Base Rent
from such commencement until the determination of Market Rent by Appraisal,
together with interest accrued thereon during such period at the Default
Interest Rate. Upon



                                       - 37 -
<PAGE>

establishment of the Base Rent for the Expansion Space, the parties agree to
execute an appropriate amendment to this Lease to reflect, as of the
Availability Date (i) the increase in the net rentable area of the Premises,
(ii) the increase in the Base Rent, and (iii) the increased Tenant's
Proportionate Share;

               (e)  As conditions precedent to Tenant's right to the Expansion
Option, at the time the Expansion Option is exercised and on the Availability
Date, this Lease must be in full force and effect, Tenant must not then be in
default thereunder and Tenant's interest under this Lease must not have been
assigned by operation of law or otherwise (except pursuant to an assignment with
respect to which Landlord has agreed in this Lease to give its consent or as to
which Landlord's consent is not required under this Lease). The foregoing
conditions are for the benefit of and may be waived by Landlord; and

               (f)  Landlord shall not be liable to Tenant for any loss or
damage for any failure to deliver possession of the Expansion Space to Tenant by
reason of the holding over or retention of possession by a tenant or occupant of
the Expansion Space and no such failure shall impair the validity of this Lease
or extend its term. Landlord will, however, exert reasonable efforts (including
legal proceedings to the full extent permitted under applicable laws) to cause
the other tenant to deliver possession of the Expansion Space.

               (g)  Tenant shall have the right to receive additional parking
with respect to the Expansion Space, at no cost to Tenant, as provided in
paragraph 4 of this Lease.

          56.  RIGHTS OF FIRST OFFER.  Tenant will have rights of first offer to
lease additional space in the Rockwell Building in accordance with the following
provisions:

               (a)  ANNUAL NOTICES.  No earlier than August 1 and no later than
October 1 of each calendar year during the term, Landlord will notify Tenant in
writing ("Annual Notice") of any rentable space within the Rockwell Building
that Landlord does not intend to warehouse, use or occupy and that is then
unleased or that will become unleased during the following calendar year in the
absence of the exercise of a Superior Right (as defined below).  The Annual
Notice will include the following:

               (1)  identification of the configurations of such space that
                    Landlord intends to use in marketing such space
                    "Configurations");

               (2)  the date on which each such Configuration that is then
                    leased will become unleased if no Superior Right (as defined
                    below) is exercised;



                                       - 38 -

                    to right of first offer, right of first refusal, renewal,
                    extension or expansion provisions in their leases ("Superior
                    Rights"), together with identification of the date on which

               (4)  Landlord's reasonable determination of Market Rent as to
                    each Configuration.

Landlord will not be required to give an Annual Notice (or any Interim Notices
or Reconfiguration Notices, as provided below, as to the calendar year to be
covered by the Annual Notice) unless, on or before July 1 of the year in which
such Annual Notice is to be given, Tenant has notified Landlord in writing of
Tenant's request that Landlord do so.

               (b)  INTERIM NOTICES.  If any rentable space within the Rockwell
Building that was not required to be included in the previous Annual Notice,
subject to the exercise of a Superior Right, becomes unleased during the
calendar year following the date that the previous Annual Notice was given to
Tenant, Landlord will notify Tenant in writing ("Interim Notice") of such fact
within 20 days after Landlord first has knowledge of such fact.  The Interim
Notice will include the following:

               (1)  the Configurations for such space;

               (2)  the date on which each such Configuration that is then
                    leased will become unleased if no Superior Right is
                    exercised;

            (3)     identification of each Superior Right applicable to each
                    such Configuration and the date on which each such Superior
                    Right terminates; and

            (4)     Landlord's reasonable determination of Market Rent as to
                    each Configuration.

               (c)  RECONFIGURATION NOTICES.  If Tenant has failed to exercise
its rights of first offer with respect to a particular Configuration identified
in an Annual Notice, as provided in this paragraph, and if Landlord subsequently
reconfigures such Configuration so that the area of such Configuration increases
or decreases by 20% or more, Landlord will, prior to such reconfiguration,
notify Tenant of such reconfiguration ("Reconfiguration Notice").  The
Reconfiguration Notice will include the following:



                                       - 39 -
<PAGE>

               (1)  the new Configurations resulting from such reconfiguration;

               (2)  the date on which each such new Configuration that is then
                    leased will become unleased if no Superior Right is
                    exercised;

               (3)  identification of each Superior Right applicable to each
                    such new Configuration and the date on which each such
                    Superior Right terminates; and

               (4)  Landlord's reasonable determination of Market Rent as to
                    each such new Configuration.

               (d)  TENANT'S ELECTION TO LEASE.  Tenant may elect to lease all
                    (and not part) of any Configuration set forth in an Annual
                    Notice, an Interim Notice or a Reconfiguration Notice as
                    follows:

               (1)  Tenant's election to lease such Configuration must be made,
                    if at all, by written notice to Landlord ("Election Notice")
                    not later than (A) the November 1 following an Annual Notice
                    and (B) 15 days after an Interim Notice or Reconfiguration
                    Notice is given to Tenant. Tenant will be deemed to have
                    elected not to lease such Configuration if the Election
                    Notice is not given to Landlord within the applicable
                    response period.

               (2)  Tenant must have first elected to lease all Configurations
                    that are then unleased before Tenant may elect to lease any
                    Configurations that are then leased.

               (3)  Tenant may not elect to lease any space under this paragraph
                    during the last two years of the initial term of this Lease
                    or any Extended Term, unless Tenant has then exercised its
                    next available option to extend the term of this Lease.

               (e)  SUPERIOR RIGHTS.  Any election by Tenant to lease a
                    Configuration will be subject to the rights of other
                    tenants having applicable Superior Rights as identified
                    in the Annual Notice, Interim Notice or Reconfiguration
                    Notice.

               (f)  COMMENCEMENT OF LEASE REGARDING CONFIGURATION.  A
                    Configuration will become a part of the Premises, upon the
                    same terms and conditions as are provided in this Lease
                    (except as expressly modified in this paragraph), upon
                    the later of (1) the date that all holders of Superior
                    Rights applicable to such Configuration have relinquished
                    their rights or the date all of such Superior Rights have
                    terminated in accordance with their terms, whichever is



                                       - 40 -
<PAGE>

earlier, or (2) the date such Configuration is delivered to Tenant, free from
rights of others.

          (g)  RENT. Base Rent for any space added to the Premises under this
paragraph will be equal to the Market Rent, determined as of the date of the
commencement of the term of this Lease with respect to such space.  If Landlord
and Tenant cannot agree upon the determination of Market Rent on or before the
date that Tenant is required to give Landlord an Election Notice, and Tenant
nonetheless elects to lease such space, the determination of Market Rent as to
such space will be submitted to Appraisal in accordance with attached EXHIBIT D.
If on the date Base Rent as to such space is scheduled to commence pursuant to
this Lease the Appraisal has not been completed, Tenant will pay Base Rent based
on Landlord's reasonable estimate of Market Rent.  Upon determination of Market
Rent by Appraisal, Landlord will pay to Tenant or Tenant will pay to Landlord,
as appropriate, the amount equal to the overpayment or underpayment of Base Rent
from such commencement until the determination of Market Rent by Appraisal,
together with interest accrued thereon during such period at the Default
Interest Rate.

          (h)  CONDITION OF SPACE.  Any space leased by Tenant under this
paragraph will be delivered to Tenant in its "as is" condition as of the
commencement of the term of this Lease as applied to such space.

          (i)  AMENDMENT TO LEASE AND MEMORANDUM OF LEASE.  Within ten (10) days
after request by Landlord or Tenant, the parties shall execute an amendment to
this Lease and to any Memorandum of Lease adding to the Premises any space which
Tenant has elected to lease pursuant to this paragraph, as of the commencement
date specified in this paragraph with respect to such space, and upon the terms
and conditions of this Lease.

          (j)  EFFECT OF DEFAULT.  If any default exists by Tenant under this
Lease that has not been cured or is being cured by Tenant within the applicable
grace period at the time the Election Notice is given or at the commencement of
the term of this Lease as to the space in question, Tenant will have no right to
exercise its option as to the applicable space and/or to lease such space.

          The time limitations with respect to Tenant's election to lease space
under this paragraph set forth in subparagraph (d) above and the condition set
forth in subparagraph (j) above are solely for the benefit of Landlord, and
Landlord may at its option waive any such limitation or condition.

          57.  ADDITIONAL ENVIRONMENTAL ASSESSMENTS; ASBESTOS REMOVAL. Landlord
will promptly obtain and provide to Tenant, in sufficient time to allow Tenant
to prepare for construction of the Tenant Improvements, the additional
environmental investigation and assessment work requested by Dana Wagner of



                                       - 41 -
<PAGE>

December 1, 1992 and a letter to Che Hsien Chang dated November 20, 1992, and
Landlord shall complete such governmental environmental reporting as shall be
required by applicable laws. Tenant will pay Landlord 50% of the reasonable cost
of such work, within 10 days of written demand. Landlord agrees that Landlord
will, at Landlord's sole expense, remove, encapsulate or otherwise address any
asbestos situated in any space leased by Tenant pursuant to this Lease when such
space is first made available by Landlord to Tenant in accordance with
applicable laws and in such a time frame (to the extent reasonably possible) as
not to interfere with the timely completion of improvements to be constructed in
such space by Tenant.

          58.  ROOF ANTENNAS.  Subject to the terms of paragraph 31 of this
Lease, Tenant may install on the roof of the Premises antenna and satellite
dishes for use in connection with its business, so long as such installation
does not interfere with the use and operation of (a) any television, radio,
communications or other equipment in any adjoining structure, or (b) any
electronic control system or elevators in any adjoining structure, or (c) any
other transmitting, receiving or master TV antenna on any adjoining structure.

          59.  CONTINGENCIES.  Tenant's obligations under this Lease shall be
contingent upon the following occurring or being satisfied on or before the
dates set forth below:

               (a)  Tenant shall receive the Letter of Credit on or before the

holder of any deed of trust that has priority over this Lease (which agreements
Landlord agrees to use its best efforts to provide to Tenant on or before the
date 25 business days after the date of this Lease and which agreements Landlord
and Tenant agree to execute).

          Tenant may waive such contingencies by written notice given to
Landlord on or before the applicable contingency date.  Tenant's failure to so
waive any such contingency on or before the applicable contingency date shall be
deemed to be an exercise of Tenant's right to terminate this Agreement based
upon the failure of such contingency.

          60.  MEMORANDUM OF LEASE; RECORDABLE TERMINATION.  Either party will,
upon the written request of the other party, execute a short form lease
("Memorandum of Lease") regarding this Lease, in a form suitable for recording

<PAGE>

the date of this Lease and will disclose the parties; the term of this Lease,
descriptions of the Premises, Tenant's extension and expansion rights and rights
of first refusal and such other terms and conditions as the parties agree upon.
The party requesting the execution of such Memorandum of Lease will bear all
costs of the Memorandum of Lease, including any recording fees. Upon the
determination of the Commencement Date and the written request of either party,
the parties will execute an amendment to the Memorandum of Lease setting forth
the Commencement Date, with the party requesting the execution of such amendment
bearing all costs of the amendment, including any recording fees. Upon the
execution of a pertinent amendment to this Lease and the written request of
either party, the parties will execute a corresponding amendment to the
Memorandum of Lease, with the party requesting the execution of such amendment
bearing all costs of the amendment, including any recording fees.  Either party
will, following any termination of this Lease and upon the written request of
the other party, execute a document setting forth the date of such termination,
in a form suitable for recording in the Los Angeles County Records.  Failure of
a party to execute such a document will not affect the termination, and in such
event the party requesting the document may execute and file an affidavit
setting forth the date of termination.  The party requesting the execution of
such document will bear all costs thereof, including any recording fees.

          61.  MISCELLANEOUS.  This Lease cannot be changed orally, but only by
agreement in writing signed by the party against whom, or against whose
successors and assigns, enforcement of the change is sought.  The voluntary or
other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall
not work a merger as to any existing subtenancies and shall, at the option of
Landlord, terminate any and all such existing subtenancies or, at Landlord 's
option, operate as an assignment to it of any and all such subtenancies.  The
words "Landlord" and "Tenant" as used herein shall include the plural as well as
the singular.  If there is more than one tenant, the obligations hereunder
imposed upon the Tenant shall be joint and several.  Time is of the essence of
this Lease and each and all of its provisions.  This Lease shall be construed
and enforced in accordance with the laws of the State of California.  The term
"Default Interest Rate" shall mean an annual rate equal to the reference or
prime rate of Bank of America ("Reference Rate"), or the successor to such rate,
plus 2 percentage points per annum, or the maximum interest rate permitted by
law, whichever is less.  Any amount due from Tenant, if not paid when first due,
shall bear interest at the Default Interest Rate from the date due until paid.
If any covenant, agreement, or condition of this Lease or the application
thereof to any person, firm, corporation, or circumstance is or becomes to any
extent invalid or unenforceable, the remainder of this Lease, or the application
of such covenant, agreement, or condition to persons, firms, corporations, or
circumstances other than.those as to which it is invalid or unenforceable, shall
not be affected thereby, and in lieu of each clause or provision of this Lease
that is illegal, invalid, or unenforceable, there shall be added as a part of
this Lease a clause or provision as



                                       - 43 -
<PAGE>

similar in terms to such clause or provision as is possible and as may be legal,
valid, and enforceable.  If any excavation or other building operation shall be
made, or is about to be made, upon any adjoining property or streets, upon the
request of Landlord, Tenant shall permit the owner or lessee of such adjoining
property and their respective representatives to enter the Premises and shore
the foundations and walls thereof, and to do any other act or thing reasonably
necessary, in Landlord's opinion, for the safety or preservation of the
Premises.  Landlord's acceptance of a partial rent payment shall not constitute
a waiver of any rights of Tenant or Landlord, including, without limitation, any
right Landlord may have to recover possession of the Premises, in unlawful
detainer, or otherwise.  The parties agree that, except as in this Lease
otherwise provided, and subject to the provisions of paragraph 35 of this Lease,
the covenants and agreements herein contained shall bind and inure to the
benefit of the successors and assigns of the parties.

          Exhibits A through F are attached hereto and become part of
this Lease.

                              APPRAISAL PROCEDURES


          The parties to this Lease will initially attempt to agree upon the
Market Rent.  If they have been unable to so agree within the period that they
are required to agree as to such matter under the Lease,  then either party may
request by written notice to the other party ("Appraisal Request") that the
matter be determined by an appraisal board consisting of three appraisers who
are members of the Appraisers Institute (or a successor or similar organization,
if such organization no longer exists) and have at least five (5) years'
experience appraising commercial real estate in the Chatsworth, California area.
One appraiser will be appointed by each party, and each such appraiser will have
no material financial or other business interest in common with the party
selecting such appraiser.  If a party fails to appoint an appraiser and notify
the other party of such appointment within 30 days after the Appraisal Request
is made, then the appraiser that was appointed by such other party within such
30 day period will be the sole appraiser.  If two appraisers are properly
appointed and such first two appraisers are unable to agree on a third appraiser
within thirty (30) days after the appointment of the second appraiser, then such
third appraiser will be appointed by the presiding judge of the Los Angeles
County Superior Court, or by any person to whom such presiding judge formally
delegates the matter, or, if such methods of appointment fail, by the American
Arbitration Association.

          The parties will submit a copy of this Lease to the sole appraiser or
the three appraisers, as the case may be.  If the appraisal is conducted by a
sole appraiser, such sole appraiser will render to Landlord and Tenant his or
her determination of the Market Rent applicable during the period in question to
the parties by the 60th day after the Appraisal Request was made. If the
appraisal is conducted by three appraisers, each appraiser will submit his or
her determination(s) of the Market Rent applicable during the period in question
in a sealed envelope by the 30th day following appointment of the last
appraiser, and any determinations not submitted by such time shall be
disregarded.  In such cases, the parties will meet on such 30th day (or if it is
not a business day, on the first business day thereafter) at 11:00 a.m. at the
office of Landlord, or such other place as the parties may agree, and
simultaneously deliver the determinations.  If the determinations of at least
two of the appraisers are identical in amount, such amount will be deemed the
decision of the appraisers.  If the determination of the three appraisers are
different in amount, the decision as to the Market Rent will be independently
determined as follows:

               (a)  If neither the highest nor lowest determination differs from
          the middle determination by more than 15% of such middle
          determination, then the decision will be deemed to be the average of
          the three determinations; and



<PAGE>

               (b)  If clause (a) does not apply, then the decision will be
          deemed to be the average of the middle determination and the
          determination closest in amount to such middle determination.


          The decision of the appraisers, determined as above set forth, will be
final and non-appealable.  The fees and expenses of the appraiser or appraisers
will be shared equally by Landlord and Tenant.

          During the period of time that any appraisal is pending under this
Lease, Tenant shall pay Base Rent at the rate that was last in effect under the
Lease and the appropriate retroactive adjustment shall be made between the
parties within 10 days after the appraisers have made their determination.

Attn:  Letter of Credit Department

Gentlemen:

          The undersigned are, collectively, the "Beneficiary" of the captioned
IRREVOCABLE STANDBY LETTER OF CREDIT (the "Standby Letter").  As the "Issuer,"
you established the Standby Letter in Beneficiary's favor for the account of the
"Customer," GREENVILLE DALLAS DELAWARE, INC.  Beneficiary hereby draws on the
Standby Letter in the amount of________________________________________________
Dollars (US$________________________).

          In support of this drawing, Beneficiary hereby certifies and warrants:

     1.   The Standby Letter was issued to back up certain of Customer's
obligations under a lease (the "Lease"), as more particularly described in the
Standby Letter.

     2.   The Customer has defaulted on one or both of the following obligations
(Beneficiary must so indicate below) imposed upon Customer by the Lease:

          (a)  Customer has failed to keep the Standby Letter in effect for the
               period of time required by paragraph 23 of the Lease [yes ____];
               or

          (b)  Customer has defaulted in the performance of Landlord's
               Environmental Indemnity in a manner and as defined in paragraph
               23 of the Lease [yes ____].

accompanying Draft:

           (i)    is an officer of the Beneficiary for which such individual

                  concerning the Standby Letter.

          IN WITNESS WHEREOF, the undersigned Beneficiary executed, attested
or otherwise officially sealed (as applicable), delivered, and presented this

interest under the Lease pursuant to the taking of a deed or assignment in lieu
of foreclosure (or similar device), nor shall Beneficiary interfere with
Tenant's use or possession of the Demised Premises unless the holder of the
landlord's interest under the Lease (the "Landlord") would have had the right to
do so if the Deed of Trust had not been made, provided that the Person (as
defined in the Deed of Trust) acquiring, or succeeding to, the interests of the
Landlord as a result of any such action or proceeding, and such Person's
successors and assigns (any of the foregoing being hereinafter referred to as
the "Successor"), shall not be:

     (a)  subject to any credits, offsets, defenses or claims which Tenant may
          have against any prior Landlord, except as permitted by the Lease or
          by statute; or

     (b)  bound by base rent which Tenant might have paid for more than the
          current month to any prior Landlord, unless such prepayment shall have
          been made with Beneficiary's prior written consent; or

     (c)  liable for any act or omission of any prior Landlord; or

     (d)  bound by any covenant to undertake or complete any improvement to the
          Demised Premises or the building forming a part of the Property except
          as expressly required of the Landlord pursuant to the Lease; or

     (e)  required to account for any security deposit other than any security
          deposit actually delivered to the Successor; or

     (f)  liable for any payment to Tenant of any sums, or the granting to
          Tenant of any credit, in the nature of a contribution towards the cost
          of preparing, furnishing or moving into the Demised Premises or any
          portion thereof except as expressly required of the Landlord pursuant
          to the Lease.

     4.   If the interest of the Landlord under the Lease shall be transferred
by reason of foreclosure or other proceedings for enforcement of the Deed of
Trust or pursuant to a taking of a deed in lieu of foreclosure (or similar
device), Tenant shall be bound to the Successor under all of the terms,
covenants and conditions of the Lease for the balance of the term thereof
remaining, with the same force and effect as if the Successor were the Landlord,
and Tenant hereby does (a) agree to attorn to



<PAGE>


the Successor, including Beneficiary if it be the Successor, as its Landlord,
(b) affirm its obligations under the Lease, and (c) agree to make payments of
all sums due under the Lease to the Successor, said attornment, affirmation and
agreement to be effective and self-operative without the execution of any
further instruments, upon the Successor succeeding to the interest of the
Landlord under the Lease.  Tenant waives the provisions of any statute or rule
of law now or hereafter in effect that may give or purport to give it any right
or election to terminate or otherwise adversely affect the Lease or the
obligations of Tenant thereunder by reason of any foreclosure or similar
proceeding.

     5.   Tenant shall not change the terms, covenants, conditions and
agreements of the Lease in a manner which materially reduces the rent or other
charges payable or space demised thereunder or has a material adverse effect
upon the value of the landlord's interest thereunder without the express consent
in writing of the Beneficiary.

     6.   Tenant shall notify Beneficiary of any default of the Landlord under
the Lease which would entitle Tenant to cancel the Lease or abate the rent or
any additional rent payable thereunder, and agrees that Beneficiary shall have
the same rights to cure any such default as are afforded to the Landlord under
the Lease.

     7.    Anything herein or in the Lease to the contrary notwithstanding, in
the event that Beneficiary shall acquire title to the Property, Beneficiary
shall have no obligation, nor incur any liability, beyond Beneficiary's then
interest, if any, in the Property and Tenant shall look exclusively to such
interest of Beneficiary, if any, in the Property for the payment and discharge
of any obligations imposed upon Beneficiary hereunder or under the Lease and
Beneficiary is hereby released or relieved of any other liability hereunder and
under the Lease.  Tenant agrees that with respect to any money judgment which
may be obtained or secured by Tenant against Beneficiary, Tenant shall look
solely to the estate or interest owned by Beneficiary in the Property and Tenant
will not collect or attempt to collect any such judgment but of any other assets
of Beneficiary.

     8.   Tenant acknowledges that it has notice that Landlord's interest under
the Lease and the rent and all other sums due thereunder have been assigned to
Beneficiary as part of the security for the note secured by the Deed of Trust.
In the event that Beneficiary notifies Tenant of a default under the Deed of
Trust and demands that Tenant pay its rent and all other sums due under the
Lease to Beneficiary, Tenant and Landlord agree that Tenant shall pay its rent
and all other sums due under the Lease to Beneficiary.

     9.   This Agreement may not be modified except by an agreement in writing
signed by the parties or their respective successors in interest. This Agreement
shall inure to the benefit of and be binding upon the parties hereto and their
respective legal representatives, successors and assigns.

     10.  Nothing contained in this Agreement shall in any way impair or affect

     11.  The Tenant agrees that this Agreement satisfied any condition or
requirement in the Lease relating to the granting of a non-disturbance agreement
by Beneficiary.  Tenant further agrees that in the event there is any
inconsistency between the terms and provisions hereof and the terms and
provisions of the Lease dealing with non-disturbance by Beneficiary, the terms
and provisions hereof shall be controlling.

buildings located at 21415 and 21605 Plummer Street, Los Angeles, California,
and more particularly described therein (the "Property").

           WHEREAS, Tenant and Landlord have entered into a certain Lease dated
December 18, 1992 (such Lease, as it may be hereafter amended from time to time
with the Beneficiary's consent, being referred to as the "Lease"), covering
certain premises (the "Demised Premises") in the Property.

           NOW, THEREFORE, in consideration of the mutual agreements herein
contained and other good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, the parties hereto agree as follows:

      1.   Tenant covenants and agrees that the Lease now is and shall at all
times continue to be subject and subordinate in each and every respect to the
Deed of Trust.  Tenant, upon request, shall execute and deliver any certificate
or other instrument which the Beneficiary may reasonably request to confirm said
subordination.

      2.   Tenant certifies that the Lease is presently in full force and effect
and unmodified and no base rent payable thereunder has been paid more than 1
(one) month in advance of its due date, and that no material default by Tenant
exists under the Lease which has continued beyond the expiration of any
applicable grace period.

<PAGE>

      3.   As long as Tenant is in compliance with the terms of this Agreement
and no default exists under the Lease which has continued beyond the expiration
of any applicable grace period, Beneficiary shall not name Tenant as a party
defendant to any action for foreclosure or other enforcement of the Deed of
Trust (unless required by law), nor shall the Lease be terminated by Beneficiary
in connection with, or by reason of, foreclosure or other proceedings for the
enforcement of the Deed of Trust, or by reason of a transfer of the landlord's
interest under the Lease pursuant to the taking of a deed or assignment in lieu
of foreclosure (or similar device), nor shall Beneficiary interfere with
Tenant's use or possession of the Demised Premises unless the holder of the
landlord's interest under the Lease (the "Landlord") would have had the right to
do so if the Deed of Trust had not been made, provided that the Person (as
defined in the Deed of Trust) acquiring, or succeeding to, the interests of the
Landlord as a result of any such action or proceeding, and such Person's
successors and assigns (any of the foregoing being hereinafter referred to as
the "Successor"), shall not be:

      (a)  subject to any credits, offsets, defenses or claims which Tenant may
           have against any prior Landlord, except as permitted by the Lease or
           by statute; or

      (b)  bound by base rent which Tenant might have paid for more than the
           current month to any prior Landlord, unless such prepayment shall
           have been made with Beneficiary's prior written consent; or

      (c)  liable for any act or omission of any prior Landlord; or

      (d)  bound by any covenant to undertake or complete any improvement to the
           Demised Premises or the building forming a part of the Property
           except as expressly required of the Landlord pursuant to the Lease;
           or

      (e)  required to account for any security deposit other than any security
           deposit actually delivered to the Successor; or

      (f)  liable for any payment to Tenant of any sums, or the granting to
           Tenant of any credit, in the nature of a contribution towards the
           cost of preparing, furnishing or moving into the Demised Premises or
           any portion thereof except as expressly required of the Landlord
           pursuant to the Lease.

      4.   If the interest of the Landlord under the Lease shall be transferred
by reason of foreclosure or other proceedings for enforcement of the Deed of
Trust or pursuant to a taking of a deed in lieu of foreclosure (or similar
device), Tenant shall be bound to the Successor under all of the terms,
covenants and conditions of the Lease for the balance of the term thereof
remaining, with the same force and effect as if the Successor were the Landlord,
and Tenant hereby does (a) agree to attorn to the Successor, including
Beneficiary if it be the Successor, as its Landlord, (b) affirm

<PAGE>

its obligations under the Lease, and (c) agree to make payments of all sums due
under the Lease to the Successor, said attornment, affirmation and agreement to
be effective and self-operative without the execution of any further
instruments, upon the Successor succeeding to the interest of the Landlord under
the Lease.  Tenant waives the provisions of any statute or rule of law now or
hereafter in effect that may give or purport to give it any right or election to
terminate or otherwise adversely affect the Lease or the obligations of Tenant
thereunder by reason of any foreclosure or similar proceeding.

      5.   Tenant shall not change the terms, covenants, conditions and
agreements of the Lease in a manner which materially reduces the rent or other
charges payable or space demised thereunder or has a material adverse effect
upon the value of the landlord's interest thereunder without the express consent
in writing of the Beneficiary.

      6.   Tenant shall notify Beneficiary of any default of the Landlord under
the Lease which would entitle Tenant to cancel the Lease or abate the rent or
any additional rent payable thereunder, and agrees that Beneficiary shall have
the same rights to cure any such default as are afforded to the Landlord under
the Lease.

      7.   Anything herein or in the Lease to the contrary notwithstanding, in
the event that Beneficiary shall acquire title to the Property, Beneficiary
shall have no obligation, nor incur any liability, beyond Beneficiary's then
interest, if any, in the Property and Tenant shall look exclusively to such
interest of Beneficiary, if any, in the Property for the payment and discharge
of any obligations imposed upon Beneficiary hereunder or under the Lease and
Beneficiary is hereby released or relieved of any other liability hereunder and
under the Lease.  Tenant agrees that with respect to any money judgment which
may be obtained or secured by Tenant against Beneficiary, Tenant shall look
solely to the estate or interest owned by Beneficiary in the Property and Tenant
will not collect or attempt to collect any such judgment but of any other assets
of Beneficiary.

      8.   Tenant acknowledges that it has notice that Landlord's interest under
the Lease and the rent and all other sums due thereunder have been assigned to
Beneficiary as part of the security for the note secured by the Deed of Trust.
In the event that Beneficiary notifies Tenant of a default under the Deed of
Trust and demands that Tenant pay its rent and all other sums due under the
Lease to Beneficiary, Tenant and Landlord agree that Tenant shall pay its rent
and all other sums due under the Lease to Beneficiary.

      9.   This Agreement may not be modified except by an agreement in writing
signed by the parties or their respective successors in interest.  This
Agreement shall inure to the benefit of and be binding upon the parties hereto
and their respective legal representatives, successors and assigns.

<PAGE>

     10.   Nothing contained in this Agreement shall in any way impair or affect
the lien created by the Deed of Trust except as specifically set forth herein.

     11.   The Tenant agrees that this Agreement satisfied any condition or
requirement in the Lease relating to the granting of a non-disturbance agreement
by Beneficiary.  Tenant further agrees that in the event there is any
inconsistency between the terms and provisions hereof and the terms and
provisions of the Lease dealing with non-disturbance by Beneficiary, the terms
and provisions hereof shall be controlling.

     12.   All notices, demands or requests made pursuant to, under, or by
virtue of this Agreement, must be in writing and mailed to the party to whom the
notice, demand or request is being made by certified or registered mail.  For

                            AND ATTORNMENT AGREEMENT



           THIS AGREEMENT, dated as of     JANUARY 4        , 1993 among
                                       ---------------------    --
GOVERNMENT OF SINGAPORE INVESTMENT CORPORATION (REALTY) PTE. LTD., a Singapore
corporation ("Beneficiary"), GREENVILLE DALLAS DELAWARE, INC., a Delaware
corporation ("Landlord"), ADC TELECOMMUNICATIONS, INC., a Minnesota corporation,
and FIBERMUX CORPORATION, a California corporation (collectively, "Tenant").

           WITNESSETH:

           WHEREAS, Beneficiary is the beneficiary under that certain deed of
trust dated as of October 3, 1986, recorded January 26, 1988 as Instrument No.
88-109752, Official Records, Office of the County Recorder of Los Angeles, State
of California (said deed of trust, as it may be amended, increased, renewed,
modified, consolidated, replaced, combined, substituted, severed, split, spread
or extended, being hereinafter referred to as the "Deed of Trust"), between
Beneficiary and the trustor described therein (predecessor in interest to the
Landlord described above), which encumbers the land and the buildings located at
21415 and 21605 Plummer Street, Los Angeles, California, and more particularly
described therein (the "Property").

           WHEREAS, Tenant and Landlord have entered into a certain Lease dated
December 18, 1992 (such Lease, as it may be hereafter amended from time to time
with the Beneficiary's consent, being referred to as the "Lease"), covering
certain premises (the "Demised Premises") in the Property.


           NOW, THEREFORE, in consideration of the mutual agreements herein
contained and other good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, the parties hereto agree as follows:

      1.   Tenant covenants and agrees that the Lease now is and shall at all
times continue to be subject and subordinate in each and every respect to the
Deed of Trust.  Tenant, upon request, shall execute and deliver any certificate
or other instrument which the Beneficiary may reasonably request to confirm said
subordination.

      2.   Tenant certifies that the Lease is presently in full force and effect
and unmodified and no base rent payable thereunder has been paid more than 1
(one) month in advance of its due date, and that no material default by Tenant
exists under the Lease which has continued beyond the expiration of any
applicable grace period.

<PAGE>

      3.   As long as Tenant is in compliance with the terms of this Agreement
and no default exists under the Lease which has continued beyond the expiration
of any applicable grace period, Beneficiary shall not name Tenant as a party
defendant to any action for foreclosure or other enforcement of the Deed of
Trust (unless required by law), nor shall the Lease be terminated by Beneficiary
in connection with, or by reason of, foreclosure or other proceedings for the
enforcement of the Deed of Trust, or by reason of a transfer of the landlord's
interest under the Lease pursuant to the taking of a deed or assignment in lieu
of foreclosure (or similar device), nor shall Beneficiary interfere with
Tenant's use or possession of the Demised Premises unless the holder of the
landlord's interest under the Lease (the "Landlord") would have had the right to
do so if the Deed of Trust had not been made, provided that the Person (as
defined in the Deed of Trust) acquiring, or succeeding to, the interests of the
Landlord as a result of any such action or proceeding, and such Person's
successors and assigns (any of the foregoing being hereinafter referred to as
the "Successor"), shall not be:

      (a)  subject to any credits, offsets, defenses or claims which Tenant may
           have against any prior Landlord, except as permitted by the Lease or
           by statute; or

      (b)  bound by base rent which Tenant might have paid for more than the
           current month to any prior Landlord, unless such prepayment shall
           have been made with Beneficiary's prior written consent; or

      (c)  liable for any act or omission of any prior Landlord; or

      (d)  bound by any covenant to undertake or complete any improvement to the
           Demised Premises or the building forming a part of the Property
           except as expressly required of the Landlord pursuant to the Lease;
           or

      (e)  required to account for any security deposit other than any security
           deposit actually delivered to the Successor; or

      (f)  liable for any payment to Tenant of any sums, or the granting to
           Tenant of any credit, in the nature of a contribution towards the
           cost of preparing, furnishing or moving into the Demised Premises or
           any portion thereof except as expressly required of the Landlord
           pursuant to the Lease.

      4.   If the interest of the Landlord under the Lease shall be transferred
by reason of foreclosure or other proceedings for enforcement of the Deed of
Trust or pursuant to a taking of a deed in lieu of foreclosure (or similar
device), Tenant shall be bound to the Successor under all of the terms,
covenants and conditions of the Lease for the balance of the term thereof
remaining, with the same force and effect as if the Successor were the Landlord,
and Tenant hereby does (a) agree to attorn to

<PAGE>

the Successor, including Beneficiary if it be the Successor, as its Landlord,
(b) affirm its obligations under the Lease, and (c) agree to make payments of
all sums due under the Lease to the Successor, said attornment, affirmation and
agreement to be effective and self-operative without the execution of any
further instruments, upon the Successor succeeding to the interest of the
Landlord under the Lease.  Tenant waives the provisions of any statute or rule
of law now or hereafter in effect that may give or purport to give it any right
or election to terminate or otherwise adversely affect the Lease or the
obligations of Tenant thereunder by reason of any foreclosure or similar
proceeding.

      5.   Tenant shall not change the terms, covenants, conditions and
agreements of the Lease in a manner which materially reduces the rent or other
charges payable or space demised thereunder or has a material adverse effect
upon the value of the landlord's interest thereunder without the express consent
in writing of the Beneficiary.

      6.   Tenant shall notify Beneficiary of any default of the Landlord under
the Lease which would entitle Tenant to cancel the Lease or abate the rent or
any additional rent payable thereunder, and agrees that Beneficiary shall have
the same rights to cure any such default as are afforded to the Landlord under
the Lease.

      7.   Anything herein or in the Lease to the contrary notwithstanding, in
the event that Beneficiary shall acquire title to the Property, Beneficiary
shall have no obligation, nor incur any liability, beyond Beneficiary's then
interest, if any, in the Property and Tenant shall look exclusively to such
interest of Beneficiary, if any, in the Property for the payment and discharge
of any obligations imposed upon Beneficiary hereunder or under the Lease and
Beneficiary is hereby released or relieved of any other liability hereunder and
under the Lease.  Tenant agrees that with respect to any money judgment which
may be obtained or secured by Tenant against Beneficiary, Tenant shall look
solely to the estate or interest owned by Beneficiary in the Property and Tenant
will not collect or attempt to collect any such judgment but of any other assets
of Beneficiary.


      8.   Tenant acknowledges that it has notice that Landlord's interest under
the Lease and the rent and all other sums due thereunder have been assigned to
Beneficiary as part of the security for the note secured by the Deed of Trust.
In the event that Beneficiary notifies Tenant of a default under the Deed of
Trust and demands that Tenant pay its rent and all other sums due under the
Lease to Beneficiary, Tenant and Landlord agree that Tenant shall pay its rent
and all other sums due under the Lease to Beneficiary.

      9.   This Agreement may not be modified except by an agreement in writing
signed by the parties or their respective successors in interest.  This
Agreement shall inure to the benefit of and be binding upon the parties hereto
and their respective legal representatives, successors and assigns.

<PAGE>

     10.   Nothing contained in this Agreement shall in any way impair or affect
the lien created by the Deed of Trust except as specifically set forth herein.

     11.   The Tenant agrees that this Agreement satisfied any condition or
requirement in the Lease relating to the granting of a non-disturbance agreement
by Beneficiary.  Tenant further agrees that in the event there is any
inconsistency between the terms and provisions hereof and the terms and
provisions of the Lease dealing with non-disturbance by Beneficiary, the terms
and provisions hereof shall be controlling.

     12.   All notices, demands or requests made pursuant to, under, or by
virtue of this Agreement, must be in writing and mailed to the party to whom the
notice, demand or request is being made by certified or registered mail.  For
such purposes, the addresses of the parties shall be as follows:

                LANDLORD, TENANT and all tenants of LANDLORD, and their
                employees, customers, and invitees to the extent of the
                adjoining landowners' contract rights.

                SECTION 3. LANDLORD agrees to manage, operate and maintain all
                common areas and common facilities within the common areas of
                the shopping center. The manner in which such areas and
                facilities shall be maintained and the expenditures therefor
                shall be at the sole discretion of LANDLORD, who shall have the
                right to adopt and promulgate reasonable nondiscriminatory rules
                and regulations, from time to time, including the right to
                designate parking areas for the use of employees of tenants of
                the shopping center and to restrict such employees from parking
                areas designated exclusively for customers. Upon reasonable
                request by LANDLORD, TENANT shall furnish a complete list of the
                name of the TENANT's employees at the leased premises who have
                automobiles and of the

                license numbers of their automobiles and the license numbers of
                all motor vehicles operated by TENANT. LANDLORD shall have the
                right to use portions of the common areas for the purpose of
                displays, promotions, programs, games, or other uses which may
                be of interest to all or part of the general public. LANDLORD
                shall have the right to close portions of the common areas from
                time to time for repairs, to prevent accruing of public rights
                therein and for any other legitimate purpose.

                SECTION 4. TENANT agrees to pay as additional rent TENANT's
                proportionate share of all expenditures incurred by LANDLORD in
                managing, maintaining, repairing, replacing, operating,
                insuring, securing, lighting and cleaning the common areas
                including, but not limited to, the cost of snow removal, line
                and exterior painting, insurance of employees, traffic
                regulation, security patrols and security guards for the entire
                shopping center, replacement of paving, curbs, sidewalks,
                landscaping, drainage, roof and lighting facilities, and
                including the cost of heating and air conditioning the shopping
                center enclosed mall and walkway areas, if any, (plus fifteen
                percent (15%) of the total of the foregoing for overhead) in
                monthly payments with the monthly rent payments. TENANT's
                proportionate share of such costs shall be based on the
                proportion the total square foot area on the ground floor in the
                leased premises bears to the total square foot rentable area on
                the ground floor in the shopping center. The monthly payments
                may be based on LANDLORD's reasonable estimate of the costs
                subject hereto made at the beginning of each lease year. At the
                end of each lease year, LANDLORD shall furnish a statement of
                all costs subject hereto and TENANT's share thereof certified to
                by LANDLORD. If, at the end of any lease year, the amount paid
                by TENANT is greater than its share as shown on said statement,
                the excess shall be credited against the next rent payments due
                hereunder. If at the end of any lease year, the amount paid by
                TENANT is less than its share as shown on said statement, the
                deficiency shall be payable with the next monthly minimum rent
                payment due hereunder.

                SECTION 3. (text deleted)

                SECTION 4. LANDLORD reserves the right, without liability to
                TENANT, to refuse admission to the shopping center and the
                leased premises outside ordinary business hours to any person
                who is not known to any watchman in charge, or who is not
                properly identified, to eject any person from the shopping
                center whose conduct may be harmful to the safety and interest
                of shopping center tenants or to close any part of the shopping
                center during any riot or other commotion where person or
                property may be imperiled.

                advertised address when referring to its business in the leased
                premises in newspaper and other advertising. The right to use
                such name for such purpose for the term of this lease is hereby
                licensed by LANDLORD to TENANT. LANDLORD retains all property

UTILITIES:      SECTION 1. TENANT shall pay for all heating, air conditioning,
                electricity, gas, water and sewer charges used in the leased
                premises throughout the term of this lease.

                SECTION 2. If TENANT receives utilities through a meter which
                utilities are also supplied to other tenants of the shopping
                center, then TENANT shall pay to LANDLORD as additional rent a
                sum equivalent to its proportionate share of the total utility
                meter charge as TENANT'S portion thereof. TENANT shall pay
                LANDLORD, as additional rent, along with TENANT'S payment of
                monthly rent a sum equivalent to TENANT'S consumption of said
                services as computed by LANDLORD.

                SECTION 3. TENANT agrees to keep the air conditioning and
                heating systems operating during business hours at levels
                sufficient to satisfy the requirements of the leased premises
                and that it will not at any time obtain or seek to obtain any
                such conditioned or heated air by methods or means which would
                draw such conditioned or heated air from the air conditioned and
                heated shopping center enclosed mall and walkway areas, if any.

                SECTION 4. LANDLORD shall not be liable in damages or otherwise
                if the furnishings by LANDLORD or by any other supplier of any
                utility or other service to the leased premises shall be
                interrupted or impaired by fire, repairs, accident, or by any
                causes beyond LANDLORD's reasonable control.

                SECTION 5. In compliance with the Federal Energy Policy and
                Conservation Act of 1975, LANDLORD has provided within the
                leased premises a heating and air conditioning system capable of
                maintaining a summer indoor condition of 78 DEG. F, and a winter

                                    ARTICLE 9

TAXES:          SECTION 1.  LANDLORD shall pay all real property taxes and
                installments of special assessments payable therewith on the
                shopping center land and improvements payable during the lease
                term and rental taxes on rentals levied during the term hereof
                upon the rentals from the leased premises. TENANT shall
                reimburse LANDLORD for TENANT's share of such payments of real
                property taxes and installments of special assessments. TENANT's
                share of such costs shall be based on the ratio that the total
                square foot floor area on the ground floor in the leased
                premises bears to the total square foot rentable floor area on
                the ground floor in the shopping center except buildings
                separately taxed or assessed for which such taxes and
                assessments are directly allocated to their tenants. TENANT
                shall also reimburse LANDLORD for rental taxes, and gross
                receipts taxes, if any, paid by LANDLORD on rentals from the
                leased premises. One-twelfth of a full year's taxes,
                installments of which are next payable, shall be payable on the
                first day of each month and added to the monthly rental. This
                amount may be based on LANDLORD's reasonable estimate until the
                actual tax amounts are available and when available an
                adjustment shall be made and any difference shall be payable
                based on TENANT's actual share as determined. TENANT's share of
                such taxes payable in the first and last calendar year of the
                lease term shall be equitably prorated based on the portion of
                the year included in the lease term. TENANT shall pay all
                personal property and similar taxes on its property in the
                leased premises.

                materials used in structural portions, and any interior and
                exterior windows and doors in the leased premises. If
                specifically required by LANDLORD, TENANT shall maintain a
                policy or policies in acceptable companies insuring LANDLORD and
                TENANT, as their interests may appear, against breakage of all
                such glass in the leased premises.

                delivering to LANDLORD the plans and specifications and copies
                of the proposed contracts and necessary permits, and shall
                furnish indemnification against liens, costs, damages and
                expenses as LANDLORD may require. All alterations, additions,
                improvements and fixtures, other than trade fixtures, which may
                be made or installed by either of the parties hereto upon the
                leased premises and which in any manner are attached to the
                floors, walls or ceiling shall, at the termination of the lease,
                become the property of LANDLORD, and shall remain upon and be

                TENANT shall bond against or discharge the same within ten (10)
                days after written request by LANDLORD. Nothing in this lease
                contained shall be construed as a consent on the part of the
                LANDLORD so as to subject the LANDLORD's estate in the leased
                premises to any lien or liability under the lien laws of the
                State in which the leased premises are located.

                claims for damages to person or property sustained by TENANT or
                TENANT's employees, agents, servants, contractors, sublessees,
                concessionaires, invitees, and customers resulting from the
                building in which the leased premises are located or by reason
                of the leased premises or any equipment or appurtenances
                thereunto appertaining becoming out of repair, or resulting from
                any accident in or about the leased premises, the building in
                which the same are situated or resulting directly or indirectly
                from any act or neglect of any other tenant in the shopping
                center. This shall apply especially, but not exclusively, to the
                flooding of the leased premises, and to damage caused by steam,
                excessive heat or cold, falling plaster, broken glass, sewage,
                gas, odors or noise, or the bursting or leaking of pipes or
                plumbing fixtures. All property belonging to TENANT or any
                occupant of the leased premises or the shopping center shall be
                there at the risk of TENANT or such person only, and LANDLORD
                shall not be liable for damage thereto or theft or
                misappropriation thereof.

                                   ARTICLE 13

INSURANCE:      SECTION 1. TENANT shall not carry any stock of goods or do
                anything in or about the leased premises which shall in any way
                tend to increase insurance rates on the leased premises or the
                building in which the same are located without the consent of
                LANDLORD. If LANDLORD shall consent to such use, TENANT agrees
                to pay as additional rental any increase in premiums for
                insurance resulting from the business carried on in the leased
                premises by TENANT. If TENANT installs any electrical equipment
                that overloads the power lines to the building, TENANT shall, at
                its own expense, make whatever changes are necessary to avoid
                such overload and to comply with the requirements of insurance
                underwriters and insurance rating bureaus and governmental
                authorities having jurisdiction.

                SECTION 2. TENANT agrees to procure and maintain a policy or
                policies of liability insurance, at its own cost and expense,
                insuring LANDLORD and TENANT from all claims, demands, or
                actions for injury or death sustained by one or more persons as
                a result of any one occurrence in the amount of One Million
                Dollars ($1,000,000), and for damage to property in an amount of
                not less than One Hundred Thousand Dollars ($100,000) made by or
                on behalf of any person or persons, firm or corporation arising
                from, related to or connected with, the conduct and operation of
                TENANT's business in the leased premises. Said insurance shall
                not be subject to cancellation except after at least ten
                (10) days' prior written notice to LANDLORD, and the policy or
                policies, or duly executed certificate or certificates for the
                same, shall be deposited with LANDLORD at the commencement of
                the term and upon any renewal of said insurance not less than
                thirty (30) days prior to the expiration of the term of such
                coverage.

                SECTION 3. LANDLORD may procure fire and extended coverage
                (including coverage for rental loss in connection with damage
                and destruction covered by the said fire and extended coverage
                insurance) and other reasonably necessary insurance on the
                shopping center. Such insurance shall be for the benefit of
                LANDLORD and TENANT shall have no interest therein. TENANT shall
                reimburse LANDLORD, monthly with its rental payments, for its
                share of the actual net cost and expense to LANDLORD of such
                insurance. TENANT's share of such costs shall be that fractional
                part of the total of such costs as the total area of the leased
                premises bears to the total rentable area of all buildings and
                structures constituting part of this shopping center.
                One-twelfth of the amount due shall be payable on the first day
                of each month and added to the monthly rental. This amount may
                be based on an estimate until the actual premiums are available
                and when available an adjustment shall be made and any
                difference shall be payable based on TENANT's actual share as
                determined.

                SECTION 4. TENANT shall maintain at its own cost and expense,
                fire and extended coverage, vandalism, malicious mischief and
                special extended coverage insurance in an amount adequate to
                cover the cost of replacement of all alterations, changes, wall
                coverings, floors, furnishings, decorations, additions, fixtures
                and improvements in the leased premises in the event of a loss,
                in companies and in form acceptable to LANDLORD. The insurance
                which the TENANT agrees to carry in this Section shall insure
                the full insurable value of the improvements and betterments
                installed by the TENANT in the leased premises, whether the same
                have been paid for entirely or partially by TENANT. TENANT will
                further deposit the certificate thereof with LANDLORD.

                SECTION 5. If TENANT fails to comply with the requirements of
                this Article 13, LANDLORD may obtain such insurance and keep the
                same in effect and TENANT shall pay LANDLORD the premium costs
                thereof on demand.

                                   ARTICLE 14

FIRE OR         SECTION 1. In case the shopping center shall be partially or
OTHER           totally destroyed by any fire or other casualty so as to become
CASUALTY:       partially or totally untenantable, the same shall be repaired at
                the expense of LANDLORD, (unless LANDLORD shall elect not to
                rebuild, as hereinafter provided), and the rent shall abate
                until the leased premises are repaired and the extent to which
                the leased premises are untenantable. SEE EXHIBIT D.

                SECTION 2. In case the shopping center buildings, including
                common areas, shall be destroyed or so damaged by fire or other
                casualty as to render more than fifty percent (50%) thereof
                untenantable, or if the unexpired term of this lease is two (2)
                years or less on the date of any substantial destruction or
                damage, then LANDLORD may, if it so elects by notice in writing
                within thirty (30) days after such destruction or damage,
                terminate this lease. The above shall apply whether or not any
                part of the leased premises is damaged or destroyed. LANDLORD's
                obligation to repair or rebuild pursuant to this Article shall
                be limited to a basic building and the replacement of any
                interior work which may have originally been installed at
                LANDLORD's cost. In no event in the case of any such destruction
                shall LANDLORD be required to repair or replace TENANT's stock
                in trade, leasehold improvements, fixtures, furniture,
                furnishings or floor coverings and equipment. TENANT covenants
                to make such repairs and replacements and to furnish LANDLORD,
                on demand, evidence of insurance assuring its ability to do so.

                                   ARTICLE 15

EMINENT         SECTION 1. If the whole of the leased premises shall be taken
DOMAIN:         under the power of eminent domain, then the term of this lease
                shall cease as of the day possession shall be taken and the rent
                shall be paid up to that date.

                SECTION 2. In the event more than ten percent (10%) of the land
                area in the shopping center is so taken, the LANDLORD shall have
                the right to terminate this lease at the time and with the rent
                adjustment as provided in Section 1 by giving TENANT written
                notice of termination within sixty (60) days after the taking of
                possession by such public authority.

                SECTION 3. If any of the floor area of the leased premises or
                forty percent (40%) or more of the parking area shall be so
                taken, then LANDLORD or TENANT shall have the right either to
                terminate this lease, or, subject, in the case of TENANT, to
                LANDLORD's rights of termination as set forth in this Article,
                to continue in possession of the remainder of the leased
                premises upon notice in writing to the other party hereto within
                thirty (30) days after such taking of possession. In the event
                this lease is not terminated, all of the terms herein provided
                shall continue in effect except that the rent shall be equitably
                abated as to any portion of the leased premises so taken and
                LANDLORD shall make all necessary repairs or alterations to the
                extent provided in Article 14, Section 2 of this lease.

                SECTION 4. All damages awarded for such taking under the power
                of eminent domain, whether for the whole or a part of the leased
                premises, shall be the property of LANDLORD, whether such
                damages shall be awarded as compensation for diminution in value
                of the leasehold or to the fee of the leased premises; provided,
                however, that LANDLORD shall not be entitled to any separate
                award made to TENANT for loss of business, depreciation of or
                cost of removal of stock and fixtures.

ASSIGNMENT      SECTION 1. TENANT shall not assign or in any manner transfer
AND SUBLETTING: this lease or any interest therein, nor sublet said leased
                premises or any part or parts thereof, nor permit occupancy by
                anyone without the prior written consent of LANDLORD. Consent by
                LANDLORD to one or more assignments of this lease or to one or
                more sublettings of the leased premises shall not operate as a
                waiver of LANDLORD's rights under this Article. No assignment
                shall release TENANT of any of its obligations under this lease
                or be construed or taken as a waiver of any of LANDLORD's rights
                hereunder. For the purposes hereof, if TENANT is a corporation
                or partnership or other entity, any change in the ownership of
                TENANT shall be deemed to be an assignment which shall require
                LANDLORD's consent as above set forth. The acceptance of rent
                from someone other than TENANT shall not be deemed to be a
                waiver of any of the provisions of this lease or consent to any
                assignment or subletting of the leased premises. SEE EXHIBIT D.

                SECTION 2. TENANT agrees not to change the advertised name of
                the place of business operated in the leased premises, which
                name shall be ADC Kentrox without prior consent of LANDLORD.
                              -----------

                SECTION 3. Neither this lease nor any interest therein, shall
                pass to any trustees or receiver in bankruptcy, or any assignee
                for the benefit of creditors, or by operation of law.

                                   ARTICLE 17

ACCESS TO       SECTION 1. LANDLORD shall have the right to enter upon the
PREMISES:       leased premises during all business hours for the purpose of
                inspecting the same or of making repairs, additions or
                alterations thereto or to the building in which the same are
                located, or for the purpose of exhibiting the same to
                prospective tenants, purchasers or others.  LANDLORD's exercise
                of such right shall not be deemed an eviction or disturbance of
                TENANT's use or possession.

                                   ARTICLE 18

REMEDIES:       SECTION 1. LANDLORD may terminate TENANT's estate herein demised
                and TENANT's right to possession hereunder upon the failure of
                TENANT to pay an installment of rent when due or to perform any
                other of its covenants under this lease and the continuance of
                such default for thirty (30) days (ten (10) days in the case of
                the payment of rent or other monetary obligations of TENANT
                hereunder) after written notice to TENANT.

                SECTION 2. If, at any time during the term of this lease (a) the
                TENANT shall file in any court a petition in bankruptcy or
                insolvency or for reorganization, or for arrangement or for the
                appointment of a receiver or trustee of all or a portion of the
                TENANT's property, or (b) an involuntary petition of any kind
                referred to in Subdivision (a) of this Section shall be filed
                against the TENANT, and such petition shall not be vacated or
                withdrawn within thirty (30) days after the date of filing
                thereof, or (c) if the TENANT shall make an assignment for the
                benefit of creditors, or (d) if the TENANT shall be adjudicated
                a bankrupt, or (e) a receiver shall be appointed for the
                property of the TENANT by order of a court of competent
                jurisdiction (except where such receiver shall be appointed in
                an involuntary proceeding, if he shall not be withdrawn within
                thirty (30) days from the date of appointment), TENANT's estate
                and right to possession hereunder shall terminate ipso facto
                upon the happening of any one of such events, and the TENANT
                shall then quit and surrender the leased premises to the
                LANDLORD, but the TENANT shall remain liable as hereinafter
                provided.

                SECTION 3. Upon the termination of the estate as aforesaid, the
                LANDLORD may re-enter the leased premises by any lawful means,
                and remove all persons and chattels therefrom and LANDLORD shall
                not be liable for damages or otherwise by reason of lawful
                re-entry or termination. Notwithstanding such termination, the
                liability of TENANT for the rent provided for hereinabove shall
                not be extinguished for the balance of the term remaining after
                said termination.

                Should termination of TENANT's estate as herein provided, or
                should LANDLORD take possession pursuant to legal proceedings or
                pursuant to any notice provided for by law, it may either
                terminate this lease or it may from time to time without
                terminating this lease, make such alterations and repairs as may
                be necessary in order to relet the premises, and relet said
                premises or any part thereof for such term or terms (which may
                be for a term extending beyond the term of this lease) and at
                such rental or rentals and upon such other terms and conditions
                as LANDLORD in its sole discretion may deem advisable; upon each
                such reletting all rentals received by the

                                        9

<PAGE>

                LANDLORD from such reletting shall be applied, first, to the
                payment of any indebtedness other than rent due hereunder from
                TENANT to LANDLORD; second, to the payment of any costs and
                expenses of such reletting, including brokerage fees and
                attorneys' fees and of costs of such alterations and repairs;
                third, to the payment of rent due and unpaid hereunder, and the
                residue, if any, shall be held by LANDLORD and applied in
                payment of future rent as the same may become due and payable
                hereunder.

                If such rentals received from such reletting during any month be
                less than that to be paid during that month by TENANT hereunder,
                TENANT shall pay any such deficiency to LANDLORD. Such
                deficiency shall be calculated and paid monthly. No such
                re-entry or taking possession of said premises by LANDLORD shall
                be construed as an election on its part to terminate this lease
                unless a written notice of such intention be given to TENANT or
                unless the termination thereof be decreed by a court of
                competent jurisdiction.

                Notwithstanding any such reletting without termination, LANDLORD
                may at any time thereafter elect to terminate this lease for
                such previous breach. Should LANDLORD at any time terminate this
                lease for any breach, in addition to any other remedies it may
                have, it may recover from TENANT all damages it may incur by
                reason of such breach, including the cost of recovering the
                leased premises, reasonable attorneys' fees, and including the
                worth at the time of such termination of the excess, if any, of
                the amount of rent and charges equivalent to rent reserved in
                this lease for the remainder of the stated term over the then
                reasonable rental value of the leased premises for the remainder
                of the stated term, all of which amounts shall be immediately
                due and payable from TENANT to LANDLORD.

                SECTION 4. In the event of any breach hereunder by TENANT,
                LANDLORD may immediately or at any time thereafter, without
                notice, cure such breach for the account and at the expense of
                TENANT. If LANDLORD at any time by reason of such breach, is
                compelled to pay, or elects to pay, any sum of money or do any
                act which will require the payment of any sum of money, or is
                compelled to incur any expense, including reasonable attorneys'
                fees, the sum or sums so paid by LANDLORD, with interest thereon
                at the rate of eighteen percent (18%) per annum or the highest
                rate permitted by law, whichever is less, from the date of
                payment thereof, shall be deemed to be due from TENANT to
                LANDLORD on the first day of the month following the payment of
                such respective sums or expenses.

                SECTION 5. LANDLORD is hereby given a lien upon all property of
                TENANT which shall come in or be placed upon the leased premises
                and whether acquired by TENANT before or after the date hereof
                to secure the payment of rent and the performance of each and
                every covenant herein contained to be performed by TENANT. Upon
                default by TENANT, and failure to cure as provided in Section 1
                of this Article, LANDLORD, with notice or demand, may take
                possession of and sell such property with legal process at
                public or private sale after one publication of a notice thereof
                in a daily newspaper published in the county where the leased
                premises are situated, not less than ten (10) days before such
                sale or by giving minimum notices required by law. The proceeds
                of any such sale shall be applied first to the payment of
                expenses thereof, second to the discharge of the rent or other

                SECTION 7. TENANT hereby expressly waives, to the full extent
                waivable, any and all rights or redemption granted by or under
                any present or future laws in the event of TENANT being evicted
                or dispossessed for any cause, or in the event of LANDLORD
                obtaining possession of the leased premises, by reason of the
                violation by TENANT of any of the covenants or conditions of
                this lease, or otherwise.

                excepted. If the leased premises are not surrendered at the end
                of the term or the sooner termination thereof, TENANT shall
                indemnify LANDLORD against loss or liability resulting from

                hereunder with the consent of LANDLORD and without execution of
                a new lease, it shall be deemed to be occupying the leased

                pay LANDLORD the cost thereof, with interest at the rate of

                proceedings are brought for the foreclosure of, or in the event
                of an exercise of power of sale under any mortgage, trust deed,
                or other financing investment, made by the LANDLORD covering the

                or stating those claimed by TENANT and certifying to such other
                matters as such party shall reasonably require. In the event
                TENANT should refuse to execute and deliver said statement
                and/or certificate, LANDLORD shall have the right to, as
                attorney-in-fact for TENANT, make such a statement, TENANT
                hereby constituting and irrevocably appointing LANDLORD its

TITLE:          SECTION 1. LANDLORD covenants that it has full right and
                authority to enter into this lease for the full term hereof.
                LANDLORD further covenants that TENANT, upon performing the
                covenants and agreements of this lease to be performed by said
                TENANT, will have, hold and enjoy quiet possession of the leased
                premises.

                                   ARTICLE 26

GENERAL:        SECTION 1. RELATIONSHIP OF PARTIES. Nothing contained herein
                shall be deemed or construed by anyone as creating the
                relationship of principal and agent or of partnership or of
                joint venture between the parties hereto.

                SECTION 2. CUMULATIVE REMEDIES AND NON-WAIVER. The various
                rights and remedies contained in this lease shall not be
                considered as exclusive of any other right or remedy, but shall
                be construed as cumulative and shall be in addition to every
                other remedy now or hereafter existing at law, in equity, or by
                statute. No delay or omission of the right to exercise any power
                by either party shall impair any such right or power, or shall
                be construed as a waiver of any default or as acquiescence
                therein. One or more waivers of any covenant, term or condition
                of this lease by either party shall not be construed by the
                other party as a waiver of a subsequent breach of the same
                covenant, term or condition. The consent or approval by either
                party to or of any act by the other party of a nature requiring
                consent or approval shall not be deemed to waive or render
                unnecessary consent to approval of any subsequent similar act.

                SECTION 3. HEADINGS. The headings of the several articles
                contained herein are for convenience only and do not define,
                limit or construe the contents of such articles.

                SECTION 4. BINDING EFFECT OF LEASE. The covenants, agreements
                and obligations herein contained, except as herein otherwise
                specifically provided, shall extend to, bind and inure to the
                benefit of the parties hereto and their respective personal
                representatives, heirs, successors and assigns. LANDLORD, at any
                time and from time to time may make an assignment of its

                receipt by LANDLORD of a lesser amount than the amount then due
                under this lease shall be deemed to be other than on account of
                the earliest portion thereof due, nor shall any endorsement or
                statement on any check or any letter accompanying any check or
                payment be deemed an accord and satisfaction, and LANDLORD may
                accept such check or payment without prejudice to LANDLORD's
                right to recover the balance due or pursue any other remedy in
                this lease provided.

                SECTION 8. NO BROKERAGE. Each of the parties represents and
                warrants that there are no claims for brokerage commissions or
                finder's fees in connection with the execution of this lease,
                except as listed below, and each of the parties agrees to
                indemnify the other against, hold it harmless from, all
                liabilities arising from any such claim for which such party is
                responsible (including, without limitation, the cost of counsel
                fees in connection therewith) except as follows.

                SECTION 9. UNENFORCEABILITY. Unenforceability of any provision
                contained in this lease shall not affect or impair the validity
                of any other provision of this lease.

                SECTION 10. GOVERNING LAW. The laws of the state in which the
                shopping center is located shall govern the validity,
                performance and enforcement of this lease.

                SECTION 11. ADDITIONAL PROVISIONS. Additional provisions, if
                any, are set forth on the attached Exhibit D, which is by
                reference made a part hereof.

                SECTION 12. EXHIBITS ATTACHED. The following exhibits are part
                of this lease agreement: Exhibit A, Shopping Center Site Plan;

                entities (or any combination of two or more thereof) shall sign
                this lease agreement as TENANT, the liability of each such
                individual, corporation, partnership or other entity to perform
                all obligations hereunder shall be deemed to be joint and
                several. In like manner, in the event that the TENANT named in
                this lease agreement shall be a partnership or other business
                association, the members of which are, by virtue of statute, or
                general law, subject to personal liability, then and in that
                event, the liability of each such member shall be deemed to be
                joint and several.

                SECTION 14. RIGHT TO REPAIR. LANDLORD shall have the right to
                install, maintain, use, repair and replace pipes, ducts,
                conduits, and wires leading through the leased premises and
                serving other parts of the building in locations which will not
                materially interfere with the TENANT's use thereof.

                SECTION 15. TENANT'S CONFLICTS. TENANT hereby covenants,
                warrants and represents that by executing this lease and by the
                operation of the leased premises under this lease, it is not
                violating, has not violated and will not be violating any
                restrictive covenant or agreement contained in any other lease
                or contract affecting the TENANT or any affiliate, associate or
                any other person or entity with whom or with which TENANT is
                related or

                                       13

<PAGE>

                connected financially or otherwise. TENANT hereby covenants and
                agrees to indemnify and save harmless LANDLORD any future owner
                of the fee or any part thereof, and any mortgagee thereof
                against and from all liabilities, obligations, damages,
                penalties, claims, costs and expenses, including attorneys'
                fees, paid, suffered or incurred by them or any of them as a
                result of any breach of the foregoing covenant. TENANT's
                liability under this covenant extends to the acts and omissions
                of any sub-tenant, and any agent, servant, employee or licensee
                of any sub-tenant of TENANT.

                SECTION 16. WAIVER OF SUBROGATION. 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, its agents (including
                partners, both general and limited), officers, directors,
                shareholders or employees, for any loss or damage that may occur
                to the leased premises, or any improvements thereto, or said
                shopping center of which the leased premises are a part, or any
                improvements thereto, or any property of such party therein, by
                reason of fire, the elements, or any other cause which could be
                insured against under the terms of standard fire and extended
                coverage insurance policies, regardless of cause or origin,
                including negligence of the other party hereto, its agents,
                officers or employees, and covenants that no insurer shall hold
                any right of subrogation against such other party.

                SECTION 17. EXECUTION OF LEASE BY LANDLORD AND LANDLORD'S
                EXCULPATION. The submission of this document for examination and
                negotiation does not constitute an offer to lease, or a
                reservation of, or option for, the leased premises and this
                document becomes effective and binding only upon the execution
                and delivery hereof by LANDLORD and TENANT. All negotiations,
                considerations, representations and understandings between
                LANDLORD and TENANT are incorporated herein and may be modified
                or altered only by agreement in writing between LANDLORD and
                TENANT and no act or omission of any employee or agent of
                LANDLORD or of LANDLORD's broker shall alter, change, or modify
                any of the provisions hereof. Further, if the LANDLORD or any
                successor in interest shall be an individual, joint venture,
                tenancy in common, firm, or partnership, general or limited,
                there shall be no personal liability on such individual or on
                the members of such joint venture, tenancy in common, firm, or
                partnership or on such joint venture, tenancy in common, firm,
                or partnership, in respect to any of the covenants or conditions
                of this lease, and in the event of any default or breach by
                LANDLORD with respect to any of the terms, covenants and
                conditions of this lease to be observed, honored or performed by
                LANDLORD, TENANT shall look solely to the estate and property of

LANDLORD'S AND TENANT'S CONSTRUCTION:

Tenant hereby acknowledges and agrees that it is aware of the requirements set
forth in the Americans with Disabilities Act 42 U.S.C. Secs. 12101-12213 (the
"ADA") and warrants that all construction done by Tenant in connection with the
terms and conditions of this lease, both in the first instance and subsequently
throughout the term of this Lease, shall be in compliance with the requirements
of the ADA.  If the Landlord grants its consent to proposed changes to be made
by the Tenant in the leased premises, the granting of such consent by the
Landlord will not mean that the Tenant's proposed changes necessarily comply
with the ADA; the question of compliance is the Tenant's responsibility.

Tenant shall hold Landlord harmless and shall protect and defend Landlord in any
cause of action brought against Landlord or to which Landlord is a defendant,
arising out of alleged violations of the ADA., wherein, by the provisions of
this Lease, Tenant was obligated to and failed to comply with any provision of
the ADA.

                              ADDITIONAL PROVISIONS



ARTICLE 1, SECTION 2 - TERM: The term of this lease shall commence upon the
earlier of (i) the date upon which Tenant opens the leased premises for
business, or (ii) September 1, 1993, and the lease term shall be three years,
plus that period of time, if any, prior to September 1, 1993 that Tenant is open
for business in the leased premises.

Tenant shall have the right to use and occupy the leased premises for the period
from the date upon which the leased premises are turned over to Tenant until the
commencement of the lease term (the "construction period") for purposes of
adapting the premises to Tenant's use under this lease.  Tenant's use and
occupancy of the leased premises during the construction period shall be
governed by all the terms and conditions of this lease, including, but not
limited to, the payment by Tenant of all charges for utility services furnished
to the leased premises; provided, however, that Tenant shall not owe or pay
Landlord any sums for minimum rent, real estate taxes, insurance, or common area
maintenance associated with the leased premises during said construction period.

ARTICLE 11, SECTION 2 - INSTALLATIONS AND ALTERATIONS BY TENANT: If Tenant uses
non-union workers to construct installations or alterations to the leased
premises pursuant to this Section 2, and any labor disputes arise as a result
thereof, Tenant shall (i) promptly resolve such dispute; and (ii) indemnify
Landlord from any and all damages suffered by Landlord as a result of Tenant's
use of said non-union labor.  Notwithstanding anything in this Section 2 to the
contrary, Tenant shall not be required to obtain Landlord's consent before
Tenant makes repairs, alterations or additions to the leased premises ("Tenant
Changes") if such Tenant Changes do not cost more than $3,000 and do not affect
or change the roof or structure of the building.

ARTICLE 12, INDEMNITY - SECTION 1:

     A.   TENANT agrees to indemnify and save LANDLORD harmless against any and
all claims, demands, damages, costs and expenses, including reasonable
attorneys' fees, arising from the conduct or management of the business
conducted by TENANT or from any breach or default on the part of TENANT in the
performance of any covenant or agreement on the part of TENANT to be performed
pursuant to the terms of this lease, or from any act or negligence of TENANT,
its agents, contractors, servants, employees, sublessees, concessionaires or
licensees, in or about the leased premises and the loading platform area
allocated to the use of TENANT.  TENANT's general liability insurance described
in Article 13, Section 2 hereof insuring LANDLORD and TENANT shall be primary
insurance coverage with no right of contribution as to all claims for damage to
person or property sustained by TENANT's employees, agents, servants,
contractors, sublessees, concessionaires, invitees, and customers resulting from
the building in which the leased premises are located or by reason of the leased
premises or any equipment or

<PAGE>

appurtenances thereunto appertaining becoming out of repair, or resulting from
any accident in or about the leased premises, or resulting directly or
indirectly from any act or neglect of any other tenant in the shopping center.
The terms of the foregoing sentence shall apply especially, but not
exclusively, to the flooding of the leased premises, and to damage caused by
steam, excessive heat or cold, falling plaster, broken glass, sewage, gas, odors
or noise, or the bursting or leaking of pipes or plumbing fixtures.  All
property belonging to TENANT or any occupant of the leased premises or the
shopping center shall be there at the risk of TENANT or such person only, and
LANDLORD shall not be liable for damage thereto or theft or misappropriation
thereof.

     B.   LANDLORD agrees to indemnify and save harmless TENANT from and against
all claims, demands, damages, costs and expenses, including reasonable
attorneys' fees, arising from any property damage or personal injury caused by
the negligent act or misconduct of LANDLORD or LANDLORD's agents, servants, or
employees, where such property damage or personal injury occurs outside of the
leased premises but within the shopping center.

ARTICLE 14, SECTION 1 - FIRE OR OTHER CASUALTY:  If Landlord fails to restore
the leased premises to tenantable condition as described in this Article within
ninety (90) days after the date of destruction, then Tenant may elect to
terminate this lease by providing Landlord with ten (10) days' prior written
notice of termination.

ARTICLE 16, SECTION 1 - ASSIGNMENT AND SUBLETTING:  Notwithstanding anything
herein to the contrary, Tenant shall have the right, without the consent of
Landlord first obtained, to assign this lease to its parent company, if any, or
to any affiliate or subsidiary corporation, or a corporation into which Tenant
shall be merged or sold, provided, however, that Tenant shall remain liable for
the performance of all Tenant obligations under this lease, and provided further
that such assignee shall agree in writing to assume all of Tenant's obligations
hereunder.

ARTICLE 26, SECTION 5 - FORCE MAJEURE:  Whenever a period of time is herein
provided for either party to do or perform any act or thing, that party shall
not be liable or responsible for any delays, and applicable periods for
performance shall be extended accordingly, due to strikes, lockouts, riots, acts
of God, shortages of labor or materials, national emergency, acts of a public
enemy, governmental restrictions, laws or regulations, or any other cause or
causes, whether similar or dissimilar to those enumerated, beyond its reasonable
control, provided the party prevented from performing gives the other party
written notice of such cause promptly after its commencement; however, either
party may terminate this lease by giving the other party written notice thereof
if such cause continues for a period of 45 days, except in the case of the
Landlord's obligation to deliver the leased premises to the Tenant at the
commencement of the initial term of this lease, in which case such right shall
arise after the expiration of 15 days after the commencement of such a cause.
The provisions of this Section 5 shall not operate to excuse TENANT

                                        2

<PAGE>

from prompt payment of rent, percentage rent, additional rent, or other monetary
payments required by the terms of this lease.

ARTICLE 26, SECTION 6 - RECORDING OF LEASE:  Either party will, upon the written
request of the other party, execute a short-form lease ("Memorandum of Lease")
regarding this lease, in a form suitable for recording.  Such Memorandum of
Lease will be dated as of the date of this lease and will disclose the parties,
the term of the lease, descriptions of the leased premises, Tenant's expansion
and extension rights, if any, and any such other terms and conditions as the
parties agree upon.  The party requesting the execution of such Memorandum of
Lease will bear all costs of the Memorandum of Lease, including any recording
fees.  Upon the execution of a pertinent amendment to this lease and the written
request of either party, the parties will execute a corresponding amendment to
the Memorandum of Lease, with the party requesting the execution of such
amendment bearing all costs of the amendment, including any recording fees.
Either party will, following any termination of this lease and upon the written
request of the other party, execute a document setting forth the date of such
termination, in a form suitable for recording.  Failure of a party to execute
such a document will not affect the termination, and in such event the party
requesting the document may execute and file an affidavit setting forth the date
of termination.  The party requesting the execution of such document will bear
all costs thereof, including any recording fees.

ENVIRONMENTAL AUDIT:  Tenant shall have the right, at Tenant's sole cost and
expense, to conduct a phase-I environmental audit of the leased premises.
Tenant may terminate this lease before the commencement of the lease term, with
ten (10) days' prior written notice to Landlord, if such audit reveals any
environmental contamination in the leased premises; provided, however, that if
Tenant terminates the lease pursuant to this provision, then (i) Tenant shall,
at Landlord's request, restore the leased premises to the condition existing at
the time of delivery of said premises to Landlord, and (ii) Tenant shall provide
Landlord with a copy of such environmental audit.

RIGHT OF FIRST REFUSAL:  If Landlord intends to lease Bay 8 (outlined in green
upon Exhibit "A" attached to this lease) to another lessee during the term of
this lease, Tenant shall have the right to lease said Bay 8 from Landlord
subject to the following terms and conditions:

     (a)  Landlord shall provide Tenant with written notice of Landlord's intent
          to lease Bay 8 to a third-party ("Prospect"), and Tenant shall have
          two business days to exercise its rights to lease Bay 8 by written
          notice to Landlord.  If Tenant fails to deliver written notice of
          Tenant's exercise of its right to lease within said two business days,
          then Landlord shall have the right to lease Bay 8 to said Prospect,
          without any further consent or act by Tenant.

                                        3

<PAGE>


     (b)  If Tenant exercises its right to lease the Bay 8 as aforesaid, Tenant
          shall lease the Bay 8 from Landlord upon the same terms and conditions
          as were offered to the Prospect, and said lease shall commence no
          later than thirty (30) days after Tenant's written notice to Landlord
          exercising Tenant's right to lease.

     (c)  Notwithstanding anything herein to the contrary, if Landlord leases
          Bay 8 to a Prospect pursuant to this Paragraph, Landlord shall have
          the right to renew or extend Landlord's lease to said Prospect or that
          Prospect's assignee or sublessee without first offering Bay 8 to
          Tenant.

RENEWAL OPTION:  Tenant shall have the option to renew the term of this lease
for one (1) period of three (3) years upon the same terms and conditions as are
provided herein except that the fixed minimum rent during said renewal term
shall be determined in the manner hereinafter provided, and there shall be no
further options to renew.

The said option shall be exercised by Tenant giving notice by certified mail to
Landlord, return receipt requested, at least one hundred eighty (180) days
before the expiration of the then existing term and not more than 365 days
before the expiration of the then existing term.  It shall be a condition of the
exercise of the foregoing option that at the time of the exercise of said
option, Tenant shall not be in default hereunder.

Within thirty (30) days after the receipt by Landlord of Tenant's exercise of
the option herein granted, the Landlord and Tenant shall commence negotiations
with regard to the fixed minimum rent to be paid by Tenant to Landlord during
the option term.  Provided, however, that in the event that Landlord and Tenant
are unable to agree on said fixed minimum rent within ninety (90) days from the
date of exercise of the option, then it shall be deemed that Tenant did not
exercise its option and the lease will terminate at the end of the then existing
term.

Notwithstanding the foregoing, Tenant's option to renew this lease may be
terminated by Landlord at any time after receipt of notice of Tenant's exercise
of the option, by notice from Landlord that it is Landlord's intention to no
longer continue to operate the shopping center as a retail shopping center.
Landlord's notice to Tenant must be given to Tenant by certified mail, return
receipt requested, not less than ninety (90) days prior to the end of the then
existing term of this lease.

                                   EXPLANATION

1.   It is intended that the signing of the stores at the Northridge Shopping
     Center shall be developed in an imaginative and varied manner.  This
     criteria shall govern for all Tenant signing at Northridge.

2.   Although previous and current signing practices of the Tenant will be
     considered, they will not govern signs to be installed at Northridge.

3.   Approval of store design drawings or working drawings and specifications
     for Tenant's leased premises does not constitute approval of any sign work.
     Landlord's written approval of Tenant's sign drawing and specifications is
     required.

4.   The furnishing and installation of a sign and the costs incurred shall be
     the responsibility of the Tenant. Sign construction is to be completed in
     compliance with the instructions contained within this criteria.

5.   Each Tenant will be required to identify its premises by a sign.

                         EXTERIOR SIGN CRITERIA-LIGHTING

     drawings will be required by our Sign Consultants.  The drawings shall
     clearly show location of sign on designated sign area, including graphics,
     color, construction, and attachment details.  Full information regarding
     electrical load requirements and brightness in foot lamberts is also to be
     included.

2.   The Sign Consultant shall return one (1) set of the sign drawings, as soon
     as possible, to the Tenant.  The drawing will either be marked "Approved,"
     "Approved Based on Landlord's Modifications," or "Disapproved." Sign
     drawings that have been "Approved Based on Landlord's Modifications" are to
     be returned to the Landlord bearing Tenant's approval, or are to be
     redesigned and resubmitted for Landlord's approval within seven (7) days of
     receipt by Tenant.  Sign drawings that have been "Disapproved" are to be
     redesigned and resubmitted to Landlord's Sign Consultant for approval, also
     within seven (7) days of receipt by Tenant.

conditions.

          1.   LEASE OF PREMISES AND DEFINITIONS.

          (b)  The term "Property" shall mean that certain real property, of
which the Premises is a part, legally described on the attached Exhibit B, on
which Property are located the Building and the building commonly known as 21605
Plummer Street ("Rockwell Building").

          (c)  The term "Tenant's Proportionate Share" shall mean the percentage
from time to time obtained by dividing the rentable area of the Premises
(including any space added to the Premises as provided in this Lease) by the sum
of the rentable area of the Building and the rentable area of the Rockwell
Building. Such rentable areas shall be initially measured, not later than the
Commencement Date, by Tenant's space planner, at Tenant's expense, in accordance
with the National Standard Method for Measuring Floor Area in Office Buildings,
ANSI Z65.1-1980 ("BOMA Standard"), which space planner shall submit such
measurements to Landlord for Landlord's approval (which approval shall be given
or withheld in writing, shall not be unreasonably withheld and shall be deemed
to be not given if not given or withheld in writing within 10 days after a
written request for such approval has been received by Landlord from Tenant).
If the rentable area of the Building, as so measured and approved, is within 1%
of 97,104 square feet, then the rentable area of the Building shall, for
purposes of this Lease, be deemed to be 97,104 square feet.  If the rentable
area of the Rockwell Building, as so measured and approved, is within 1% of
130,572 square feet, then the rentable area of the Rockwell Building shall, for
purposes of this Lease, be deemed to be 130,572 square feet.  If the Building

altered building(s) to be remeasured by a qualified party in accordance with



<PAGE>

the BOMA Standard, which remeasurements shall be submitted top Tenant for
Tenant's approval (which approval shall be given or withheld in writing, shall
not be unreasonably withheld and shall be deemed to be not given if not given or
withheld in writing within 10 days after a written request for such approval has
been received by Tenant from Landlord).  If the rentable area of the Building or
of the Rockwell Building, as so remeasured and approved, is within 1% of the
actual or deemed rentable area of the Building or Rockwell Building applicable

Lease, be deemed to be the actual or deemed rentable area of the Building or of
the Rockwell Building applicable under this Lease immediately prior to the
alteration(s).  If less than all of the Rockwell Building is added to the
Premises pursuant to this Lease, Landlord shall, at Landlord's expense, cause
the added space to be measured by a qualified party in accordance with the BOMA
Standard, which measurement shall be submitted to Tenant for Tenant's approval
(which approval shall be given or withheld in writing, shall not be unreasonably
withheld and shall be deemed to be not given if not given or withheld in writing
within 10 days after a written request for such approval has been received by
Tenant from Landlord). The parties to this Lease shall execute an amendment to
this Lease establishing Tenant's Proportionate Share and the rentable areas of
the Premises, the Building and/or the Rockwell Building, if necessary, at the
time of the initial measurement and each subsequent measurement.

          (d)  "Appraisal" shall mean an appraisal of Market Rent (as defined in
this Lease below) conducted in accordance with the procedures set forth in

the commencement date of the term in question if it were to lease the space in
question pursuant to the terms of this Lease (except to the extent that this
Lease is inconsistent with the assumptions and requirements set forth below) to
a tenant with a credit standing comparable to that of Tenant; with parking
rights as provided in this Lease; for a term equal to the period in question;
with a commencement date of the date in question; and in an "as is" condition,
except to the extent that Landlord is required under this Lease to make
improvements.  In determining the "Market Rent", current conditions in the
marketplace for comparable transactions shall be considered, including without
limitation, tenant inducements, if and to the extent then a part of market
conditions, such as, but not limited to, buildout allowances or work, free rent,
financial inducements and credits for moving expenses.  For purposes of
determining Market Rent it shall be assumed that Landlord and Tenant are each
ready, willing and able to enter into such a lease but are under no compulsion
to do so.

Index issued by the U.S. Department of Labor, Bureau of Labor
Statistics for Urban Wage Earners and Clerical Workers, U.S. City Average
(1982-1984=100), or its successor index

          2.   TERM.  The initial term of this Lease shall commence on the
Commencement Date (defined below) and shall end on the last day of the 72nd
month thereafter.

          Landlord agrees to use its best efforts (including appropriate legal
proceedings, if reasonably required) to enforce that certain Agreement dated
December 1, 1992, between Landlord and Symbolics, Inc. and that certain letter
agreement dated November 6, 1992, among Landlord, Rockwell International
Corporation ("Rockwell") and Symbolics, Inc., copies of which have been provided
to Tenant.  The Commencement Date shall be the earlier of the date that Tenant
commences business operations in the Premises or the date 180 days following the
date of this Lease, unless Rockwell's vacation of the Premises is delayed beyond
February 28, 1993, in which case the Commencement Date shall be extended by the
number of days (not to exceed 30 days) of such delay.  If such delay exceeds 30
days, Tenant shall have the option to (a) terminate this Lease or (b) continue
with the extension of the Commencement Date for such period (not to exceed 30
days) as Tenant shall determine, such option to be exercised by Tenant by
written notice given to Landlord within 10 days after the expiration of the
initial 30-day period of delay referred to above.  Tenant shall have full
occupancy of the Premises immediately following Rockwell's vacation of the
Premises until the Commencement Date in order to construct the Tenant
Improvements and move into the Building. Such occupancy shall be subject to each
and every provision of this Lease except that Tenant shall not be obligated to
pay any Base Rent or Impositions applicable to the period prior to the
Commencement Date. Upon determination of the Commencement Date, Landlord and
Tenant will execute an agreement confirming the Commencement Date.

          3.   RENT.  Tenant shall pay to Landlord, in advance, on the
Commencement Date and on the 1st day of each calendar month thereafter during
the initial term of this Lease, the following net monthly rental ("Base Rent"),
over and above the other and additional payments to be made by Tenant as
hereinafter provided, as follows:




                                       - 3 -

<TABLE>
<CAPTION>

                                          Base Rent to
       Months                           be paid per month
- ----------------------                  -----------------
<S>                                     <C>
1st month                               $77,000.00
2nd through 5th month                   $        0
6th through 9th month                   $38,500.00
10th through 36th month                 $77,000.00
37th through 72nd month                 $77,000.00, subject to the following
                                                    increase.

</TABLE>
; provided, however, that the Base Rent payable for the first month shall be
reduced by $2,531.50 for each day that Tenant's commencement of business
operations in the Premises is later than the date 150 days after the date of
this Lease (but such reduction shall in no event exceed $77,000). Commencing
with the first day of the 37th month of the initial term hereof, the Base Rent
shall be increased based upon the percentage increase in the Consumer Price
Index, as such Index for the 36th month of the initial term hereof bears to such
Index for the month preceding the first full month of the initial term;
provided, however, that in no event shall the monthly Base Rent commencing on
the 37th month of the initial term be more than $88,550.00 or less than
$83,930.00.

          Notwithstanding the foregoing, if the rentable area of the Premises is
deemed, pursuant to paragraph 1(c) of this Lease, to be an amount other than
97,104 square feet, then Tenant shall pay to Landlord, in advance, on the
Commencement Date and on the 1st day of each month thereafter during the initial
term of this Lease, the following Base Rental, rather than the Base Rental set
forth in the immediately preceding grammatical paragraph:

<TABLE>
<CAPTION>

                                          Base Rent to
       Months                           be paid per month
- ----------------------                  -----------------
<S>                                     <C>
1st month                               $.793  per rentable square foot
2nd through 5th month                   $   0
6th through 9th month                   $.3965 per rentable square foot
10th through 36th month                 $.793  per rentable square foot
37th through 72nd month                 $.793  per rentable square foot, subject
                                               to the following increase.
</TABLE>

; provided, however, that the Base Rent payable for the first month shall be
reduced by $.02607 per rentable square foot for each day that Tenant's
commencement of business operations in the Premises is later than the date 150
days after the date of this Lease (but such reduction shall in no event exceed
$.793 per rentable square foot for one month). In such case, commencing with the
first day of the 37th month of



                                       - 4 -
<PAGE>

the initial term hereof, the Base Rent shall be increased based upon the
percentage increase in the Consumer Price Index, as such Index for the 36th
month of the initial term hereof bears to such Index for the month preceding the
first full month of the initial term; provided, however, that in no event shall
the monthly Base Rent commencing on the 37th month of the initial term be more
than $.9120 per rentable square foot or less than $.8644 per rentable square
foot.

          The foregoing Base Rent schedules refer to calendar months beginning
with the first full calendar month of the initial term of this Lease.
Accordingly, if the Commencement Date is other than the first day of a calendar
month, the Base Rent for the partial month preceding the first full calendar
month of the initial term of this Lease, which is payable on the Commencement
Date, shall be determinated on a prorated basis, using for such determination
the monthly Base Rent stated above with respect to the 10th calendar month.

          The term "rent" as used in this Lease shall refer collectively to the
Base Rent and to all additional rent, charges and other sums payable hereunder.
Tenant hereby acknowledges that late payment by Tenant to Landlord of rent and
other sums due hereunder after the expiration of any applicable grace period
will cause Landlord to incur costs not contemplated by this Lease, the exact
amount of which will be difficult to ascertain.  Such costs include, but are not
limited to, processing and accounting charges, and late charges which may be
imposed on Landlord by the terms of any trust deed covering the Premises.
ACCORDINGLY, IF ANY INSTALLMENT OF RENT OR ANY OTHER SUMS DUE FROM TENANT SHALL
NOT BE RECEIVED BY LANDLORD WHEN DUE OR IF A GRACE PERIOD IS APPLICABLE, PRIOR
TO THE EXPIRATION OF THE GRACE PERIOD, TENANT SHALL PAY TO LANDLORD A LATE
CHARGE EQUAL TO 5% OF SUCH OVERDUE AMOUNT.  THE PARTIES HEREBY AGREE THAT SUCH
LATE CHARGE REPRESENTS A FAIR AND REASONABLE ESTIMATE OF THE COSTS LANDLORD WILL
INCUR BY REASON OF LATE PAYMENT BY TENANT BASED UPON THE CIRCUMSTANCES EXISTING
AS OF THE DATE OF THIS LEASE. [INITIALS OF THE PARTIES AS TO THE TWO SENTENCES
SHOWN IN BOLD: _______________________]

          4.   PARKING.  Tenant shall have the right to use 215 parking spaces
on the Property in the Fibermux Area shown on the attached EXHIBIT A ("Fibermux
Area").  Landlord, using reasonable efforts, shall also attempt to obtain
parking for an additional 173 vehicles (the "Additional Parking Spaces").  Any
Additional Parking Spaces not provided within the Fibermux Area shall be
provided first (a) in the Rockwell Area shown on the attached EXHIBIT A
("Rockwell Area"), and (b) then at 21540 Plummer Street (across the street from
the Premises).  All Additional Parking Spaces to be provided by Landlord shall
meet applicable governmental requirements and shall be approximately the same
size as the existing spaces in the Fibermux and Rockwell Areas shown on the
attached EXHIBIT A.  All parking spaces to be provided by Landlord in the
Fibermux Area and the other areas shall be identified and controlled in a manner
reasonably acceptable to Landlord and Tenant. Such parking spaces shall also be
non-tandem and shall be on the basis of the



                                       - 5 -
<PAGE>

existing stall striping; provided, however, that Tenant may, in its sole
discretion, elect to permit Landlord to provide some or all of the Additional
Parking Spaces on a tandem basis; and provided further, however, that Tenant may
restripe the delivery area of the Premises and/or the parking spaces on any
parking area provided by Landlord for Tenant's use, at Tenant's sole expense,
and in such event the number of additional parking spaces yielded by such areas
after such restriping by Tenant shall be deemed to be "Additional Parking
Spaces" for purposes of this Lease.

          For each month after the Commencement Date and continuing through the
initial term of this Lease, so long as 173 Additional Parking Spaces are not so
provided, Landlord shall pay to Tenant on the first day of each such month a sum
equal to $45.00 times the number of such Additional Parking Spaces not so
provided for that month; provided, however, that for the first seven months
following the Commencement Date, the sum due from Landlord for each such
Additional Parking Space not provided shall only be $22.50; and provided
further, however, that, if Tenant adds Additional Parking Spaces as a result of
its restriping of the Fibermux Area as provided above, Landlord shall have no
obligation to make such payments with respect to such added spaces from and
after the date that they are added to the Fibermux Area. Tenant shall deduct
such amounts due for each month of the initial Lease term from the monthly
rental payment for such month; provided, however, that, as to the 1st through
5th full calendar months following the Commencement Date, the sums due from
Landlord shall be deducted by Tenant from the payment of Base Rent due for the
6th full calendar month following the Commencement Date (and, if necessary, the
Base Rent payments due in subsequent months) under this Lease.

          From and after the date Tenant has more than 215 parking spaces on the
Property (except to the extent that such excess parking spaces are leased to
Tenant as a result of Tenant's exercise of the Expansion Option), such payments
of $45.00 per month or $22.50 per month, as the case may be, shall cease with
respect to each such space in excess of 215 spaces. For each Additional Parking
Space provided by Landlord in the locations described in subparagraphs (a) and
(b) above after the date of this Lease, the amount otherwise payable by Landlord
hereunder shall be reduced by $30.00 per month for each such Additional Parking
Space so provided.

          Tenant may enter into a lease or leases for parking at other than the
sites described in subparagraphs (a) and (b) above for: those Additional Parking
Spaces which Landlord does not commit by a written notice delivered to Tenant by
February 1, 1993 to provide to Tenant as of the Commencement Date; or any
Additional Parking Spaces that are provided by Landlord at any time during the
initial term of this Lease and are thereafter, during such initial term,
terminated by any landlord(s) thereof.  Landlord shall provide at least 75 days'
prior written notice to Tenant if Landlord will be providing Additional Parking
Spaces after the



                                       - 6 -
<PAGE>

Commencement Date.  Landlord shall provide at least 75 days' prior written
notice to Tenant if Landlord will cease to provide any Additional Parking
Spaces, in which case Tenant shall be entitled to enter into parking leases to
replace such Additional Parking, as provided above.  Notwithstanding the
foregoing, notices from Landlord to Tenant of either the provision or cessation
of Additional Parking Spaces which result from the elimination of any parking
permitted by the City of Los Angeles upon its easement area shall be the 75 days
notice specified above or the number of days of notice of elimination of parking
Landlord receives from the City of Los Angeles, whichever is less. Within ten
(10) days after entering into any parking lease, Tenant shall provide a copy
thereof to Landlord.  If Landlord thereafter provides to Tenant the Additional
Parking Spaces required on either of the sites described in subparagraphs (a) or
(b) above, and Tenant consequently cancels its parking lease(s), Landlord shall,
at Landlord's election made by written notice to Tenant at the time such
Additional Parking Spaces are delivered to Tenant, either reimburse Tenant for
the lease cancellation charge for each such canceled parking space or pay Tenant
$15 per month for the remainder of the initial term of this Lease for each
parking space as to which Landlord has elected not to pay the such cancellation
charge.  Such reimbursement by Landlord to Tenant for lease cancellation charges
shall include Tenant's unamortized costs of improving such parking site, based
on a six-year amortization period.

          Notwithstanding the foregoing provisions of this paragraph 4, if
Rockwell ceases to lease all or any portion of the Rockwell Building, then the
following shall apply:

          (1) If Rockwell at any time no longer leases any space in the Rockwell
Building, then a portion of the parking spaces in the Rockwell Area will be
added, at no cost to Tenant, to the parking spaces already available to Tenant,
which portion shall be determined by adding together the parking spaces then in
the Rockwell Area and the Fibermux Area, dividing such sum by the total rentable
square footage of the Rockwell Building and of the Building, multiplying such
dividend (the "Dividend") by the rentable area of the Building and subtracting
the number of parking spaces in the Fibermux Area from the result.  The
resulting figure will be rounded to the nearest whole number. If Tenant has then
exercised or subsequently exercises the Expansion Option, then another portion
of the parking spaces in the Rockwell Area will be provided to Tenant, at no
cost to Tenant, which portion shall be determined by multiplying the Dividend by
the rentable area of the Expansion Space, the resulting figure to be rounded to
the nearest whole number.

          (2) If Rockwell continues to lease a part of the Rockwell Building,
then a portion of the parking spaces in the Rockwell Area will be added, at no
cost to Tenant, to the parking spaces available to Tenant in the Fibermux Area,
which portion shall be determined as follows:



                                       - 7 -
<PAGE>

               [total parking spaces in the Rockwell Area] - [(total parking
               spaces in the Rockwell Area) x (rentable area of the portion of
               Rockwell Building being leased by Rockwell) divided by rentable
               area of Rockwell Building] - [(total parking spaces on the
               Property) x (rentable area of the portion of the Rockwell
               Building that is not being leased by Rockwell) divided by (total
               rentable area of the Building and the Rockwell Building)],
               rounded to the nearest whole number

                    PLUS, IF TENANT HAS THEN EXERCISED OR
               SUBSEQUENTLY EXERCISES THE EXPANSION OPTION:

               [total parking spaces on the Property x (rentable area of the
               Expansion Space) divided by (total rentable area of the Building
               and the Rockwell Building)], rounded to the nearest whole number

If Rockwell at any time no longer leases any portion of the Rockwell Building,
spaces shall be reallocated as provided in subparagraph (1) above,
notwithstanding that parking spaces may have been previously allocated pursuant
to subparagraph (2) above. The parking spaces made available to Tenant under
subparagraphs (1) and (2) above shall be as close as possible to the space
leased by Tenant and served by such parking. Such added parking spaces shall be
deemed to be Additional Parking Spaces as follows:

               (A)  if Tenant does not elect to lease any Expansion Space
              pursuant to paragraph 55 of this Lease, then all such added
              parking spaces shall be deemed to be Additional Parking Spaces; or

               (B)  if Tenant elects to lease any Expansion Space pursuant to
          paragraph 55 of this Lease, then all such added parking spaces shall
          be deemed to be Additional Parking Spaces, except for the portion of
          such added parking spaces leased to Tenant with respect to the
          Expansion Space as provided above.

If any of the approximately 97 parking spaces in the Rockwell Area that are
located upon an easement granted by the City of Los Angeles are eliminated
because such easement is revoked in whole or in part by the City of Los Angeles,
and if such elimination results in a reduction in the number of parking spaces
that would otherwise have been provided to Tenant as set forth above, then
Landlord shall for the remainder of the initial term of this Lease pay to
Tenant, on the first day of each month during which such parking spaces would
otherwise have been provided to Tenant as set forth above, a sum equal to $45.00
times the number of parking spaces that would otherwise have been provided to
Tenant as set forth above.

          5.   FULL NET LEASE.  Landlord shall receive the rent free and clear
of any and all other impositions, taxes, liens, charges, or expenses of any
nature whatsoever in connection with the ownership and operation of the
Premises, except as herein expressly provided.  In addition to the rent reserved
above, Tenant shall pay to the parties respectively entitled thereto all
impositions, insurance premiums, operating charges, maintenance charges,
construction costs, and any other charges, costs, and expenses that arise or may
be contemplated under any provisions of this Lease during the term hereof. It is
the intention of the parties that this Lease shall not be terminable for any
reason by Tenant, and that Tenant shall in no event be entitled to any set-off
against, abatement of, or reduction in rent payable under this Lease, except as
herein otherwise expressly provided (including, without limitation, the
provisions of paragraph 43 of this Lease).

          6.   USE.  The Premises shall be used and occupied only for the
businesses of testing, assembly, fabrication, warehousing and/or shipping of
electronic components, circuit boards and/or cabinets, and for sales and/or
general office uses related to such types of businesses and for other uses
incidental to the foregoing and for no other use or purpose.

          7.    QUIET ENJOYMENT.  Provided Tenant performs its obligations
hereunder, Tenant shall lawfully and quietly occupy the Premises during the term
of this Lease without hindrance or molestation by Landlord, subject, however, to
the matters herein set forth; provided, however, that, if Tenant is dispossessed
of all or part of the Premises by any party who or which does not claim such
possession through Tenant, Tenant shall be entitled to an equitable abatement of
Base Rent, Impositions, Insurance Costs and other charges under this Lease from
the date of Tenant's dispossession until Tenant's possession is restored and, if
Tenant's possession is not restored within 60 days after Tenant was
dispossessed, Tenant may terminate this lease by written notice given to
Landlord within ten (10) days after the expiration of such 60-day period and
before Tenant's possession is restored.

          8.   PAYMENT OF IMPOSITIONS.  Tenant covenants and agrees to pay to
Landlord Tenant's Proportionate Share (as defined in paragraph 1(c) of this
Lease) of all "Impositions" upon or with respect to the Property.  As used
herein, the term "Impositions" shall include any form of real estate tax,
assessment, license fee, commercial rental tax, improvement bond or bonds, levy,
or other tax, general and special, ordinary and extraordinary, foreseen as well
as unforeseen, of any kind or nature whatsoever, imposed by any authority having
the power to tax (including any city, state, or federal government, or any
school, agricultural, sanitary, water, fire, street, drainage, or other
improvement district thereof ) against any legal or equitable interest of
Landlord in the Premises or in the Property, against Landlord's right to rent or
other income therefrom, and against Landlord's business of leasing the Premises
or the Property; provided, however, that "Impositions" shall not include
inheritance, personal or corporate income, or estate taxes.  The term



                                       - 9 -
<PAGE>

"Impositions" shall also include any tax, fee, levy, assessments, or charge: (a)
in substitution of, partially or totally, any of the above-listed Impositions,
or (b) that is imposed by reason of this transaction, any modifications or
changes hereto, or any transfers hereof. Except as otherwise provided in this
Lease, all such payments shall be made at least fifteen (15) days prior to the
delinquency date. Tenant shall have the right to contest Impositions if there
are reasonable grounds to do so or, if Tenant may not legally do so, to cause
Landlord to do so at Tenant's expense.

          9.   PERSONAL PROPERTY TAXES.  Tenant shall pay prior to delinquency
all taxes assessed against and levied upon trade fixtures, furnishings,
equipment, and all other personal property of Tenant contained in the Premises
or elsewhere.

          10.  UTILITIES.  Tenant shall pay all utility deposits and fees, and
all monthly service charges for heat, water, gas, electricity, sewer service,
elevator (if there be any) and cleaning service, telephone service, and any
other utilities or services whatsoever furnished to the Premises during the term
of this Lease.

          11.  PROPERTY INSURANCE.  Landlord shall procure and maintain
throughout the terms of this Lease all-risk property and liability insurance
insuring the Property (including improvements and betterments, boilers and
machinery owned by Landlord, but excluding all equipment, trade fixtures,
inventory, machinery and other personal property of the Tenant); provided,
however, that Tenant shall maintain builder's risk insurance reasonably
satisfactory to Landlord effective from the commencement of construction of the
Tenant Improvements until the Commencement Date and Landlord's all-risk
insurance shall insure the Tenant Improvements from and after the Commencement
Date. Landlord's all-risk insurance shall insure the Property against risk of
direct physical loss (including loss caused by the perils of earthquake and, if
the Property is in an officially designated flood hazardous area, flood).
Landlord's insurance shall be in an amount equal to the actual replacement cost
of the Property (exclusive of foundations and excavations) without deduction for
physical depreciation, without a coinsurance clause and with a deductible not in
excess of $50,000.  The property insurance carrier shall have an A. M. Best
Company rating of A:VII or better.  Tenant agrees not to do, or fail to do,
anything which will violate the reasonable and customary terms of any such
insurance to the extent such terms are set forth in policies, copies of which
are delivered to Tenant, or otherwise disclosed to Tenant, increase the cost of
such insurance beyond a reasonable level (unless Tenant agrees to pay such
increase) or prevent Landlord from procuring policies reasonably satisfactory to
Landlord. Within ten days of billing by Landlord, Tenant will reimburse Landlord
for Tenant's Proportionate Share of the lesser of (a) all costs of such property
insurance carried by Landlord with respect to the Property, and (b) all costs
which would have been charged by an identically rated carrier (other than
Landlord's carrier) for the same coverage ("Insurance Costs"). Certificates
evidencing all such insurance coverages shall be delivered to Tenant by the date
of this Lease.  Such certificates of insurance



                                       - 10 -
<PAGE>

will provide for thirty (30) days advance notice to Tenant and Landlord in the
event of cancellation or nonrenewal of such insurance.

          12.  OTHER INSURANCE.  Tenant agrees to maintain in full force and
from the Date of this Lease and in effect at all times during the term of this
Lease, at no expense to Landlord, for the protection of Tenant and Landlord, as
their interest may appear, policies of insurance issued by a responsible carrier
or carriers reasonably acceptable to Landlord which afford the following

               (a)  Worker's Compensation - Statutory limits;

               (b)  Employer's liability - Not less than:

                    Bodily Injury by Disease - $250,000 each employee; and

               (c)  Commercial General Liability Insurance on a coverage form at

the Landlord as Additional Insured using an endorsement form at least as broad

</TABLE>

Such Commercial General Liability Insurance shall cover Bodily Injury, Personal
Injury and Property Damage Liability occasioned by or arising out of or in
connection with the use, operation and occupancy of the Premises. Such
Commercial General Liability Insurance policy must cover events that occur
during the policy period regardless of when the claim is made.  Such insurance
shall be primary insurance to any other insurance that may be available to
Landlord.  Any other insurance available to Landlord shall be non-contributing
with and excess to this insurance.



                                       - 11 -
<PAGE>

          Certificates evidencing all such insurance coverages shall be
delivered to Landlord by the date of this Lease.  Such certificates of insurance
will provide for thirty (30) days advance notice to Tenant and Landlord in the
event of cancellation or nonrenewal of such insurance.

          13.  LOSS PAYABLE REQUIREMENTS.  All policies of insurance required
hereunder shall provide that the proceeds thereof shall be payable to Tenant and
Landlord, as their respective interests may appear, and, if Landlord so elects,
the policies referenced in paragraph 11 may be payable also to the holder of any
mortgage or deed of trust on the Premises as the interest of such holder may
appear, pursuant to a standard mortgagee clause or a loss payable clause.

          14.  WAIVER OF CLAIMS.  Each party to this Lease hereby releases the
other from any and all claims, and waives its entire right of recovery against
the other, for loss or damage arising out of or incident to the perils insured
against under the policies specified in paragraphs 11 and 12 above to the extent
such loss or damage is insured against under such policies, whether due to the
negligence of such parties or the agents, employees, contractors, or invitees of
either of them. Tenant also waives all claims against Landlord with respect to
Tenant's personal property in the Premises.

          15.  LANDLORD'S RIGHT TO PERFORM TENANT'S COVENANTS. Tenant agrees
that, if Tenant shall at any time fail to make any payment or perform any other
act to be made or performed by it under this Lease, Landlord may, but shall not
be obligated to, make such payment or perform such other act to the extent
Landlord may deem desirable, with full rights of offset, and without waiving or
releasing Tenant from any obligation under this Lease.  All sums so paid by
Landlord and all expenses paid in connection therewith, including without
limitation attorneys' fees, together with interest thereon at the Default
Interest Rate (defined in the paragraph of this Lease entitled "Miscellaneous")
from the date of such payment, shall be paid by Tenant to Landlord on demand.

          16.  MAINTENANCE AND REPAIR.  Except as otherwise set forth in this
Lease, Tenant shall, at Tenant's sole cost and expense, keep the entire Premises
(and every part thereof, including, without limitation, the roof membrane)
secure, clean and in good order, condition, and repair, and shall make promptly
all necessary repairs, interior and exterior, ordinary as well as extraordinary,
foreseen as well as unforeseen, casualty and condemnation excepted; provided,
however, that Landlord shall be responsible for maintaining and repairing the
foundation, the structure of the exterior walls and of the roof and the other
structural members of the Building in accordance with prudent property
management standards, unless the need for such maintenance and repair results
from Tenant's failure to satisfy its maintenance and repair obligations with
respect to the remainder of the Premises or (subject to



                                       - 12 -
<PAGE>

the provisions of paragraphs 11 and 14 of this Lease) the negligence or
intentional acts of Tenant, its employees, agents, contractors or invitees.
Tenant shall also, at Tenant's sole cost and expense, keep the entire Fibermux
Area and any portions of the Rockwell Area provided by Landlord to Tenant for
parking pursuant to paragraph 4 of this Lease or any other provision of this
Lease (including, but not limited to, all paving, striping, landscaping and
attendant driveways, entrances, walkways, curbs, gutters, drains and the like)
clean and in good order, condition and repair, and shall make promptly all
necessary repairs, ordinary as well as extraordinary, foreseen as well as
unforeseen.  When used in this paragraph, the term "repair(s)" shall include
alterations, replacements, and renewals.  All repairs shall be equal in quality
and class to the original work.  Landlord shall have no obligation, in any
manner whatsoever, to repair or maintain the Premises, except as specifically
otherwise provided in this Lease.  Landlord may, at its option, perform Tenant's
repair obligations under this Lease at Tenant's expense if Tenant does not do so
within the applicable cure period provided for in this Lease.

          17.  SURRENDER OF PREMISES.  Upon expiration or any sooner termination
of this Lease, Tenant shall surrender to Landlord the entire Premises, together
with all Alterations (as defined in paragraph 25 of this Lease), in the same
condition as when received or installed (unless such Alterations are to be
removed pursuant to paragraph 24 of this Lease), ordinary wear and tear and
casualty and condemnation excepted, and clean and free of debris and free of any
liens created or suffered to be created by Tenant and (b) Tenant shall properly
remove from the Premises all Hazardous Materials for which it has responsibility
under this Lease. Tenant may, and upon Landlord's request shall, remove any
Trade Fixtures or personal property belonging to Tenant, provided that Tenant
shall perform prior to expiration of the term of this Lease all restoration made
necessary by such removal. Landlord may, at Tenant's expense, retain or dispose
of in any manner any Trade Fixtures or personal property of Tenant that Tenant
does not remove from the Premises upon expiration or termination of the term of
this Lease, in which case title thereto shall vest in Landlord. The term "Trade
Fixtures" as used herein shall mean all fixtures, equipment, and personal
property owned by Tenant and used in connection with the operation of any
business on the Premises, whether or not affixed to the Premises.

          18.  SERVICE CONTRACTS.  Tenant shall, at Tenant's sole cost and
expense, either (a) enter into a regularly scheduled preventive
maintenance/service contract with a maintenance contractor for servicing all hot
water, heating, and air conditioning systems, elevators (if there be any) and
building equipment within the Premises or (b) provide similar services through
the use of its own qualified employees.  The maintenance contractor and the
contract, or the employees of Tenant, as the case may be, shall be subject to
the approval of Landlord (which approval shall be given or withheld in writing,
shall not be unreasonably withheld and shall be deemed to be not given if not
given or withheld in writing within 10



                                       - 13 -
<PAGE>

days after a written request for such approval has been received by Landlord
from Tenant).  The contract or employee-provided services shall include all
services suggested by the equipment manufacturers and shall become effective,
and a copy thereof shall be delivered to Landlord, within thirty (30) days of
the date Tenant takes possession of the Premises. Landlord shall deliver to
Tenant the service manuals for the items to be serviced as provided in this
paragraph and shall deliver and assign to Tenant all warranties covering such
items.

          19.  WASTE.  Tenant shall not do or suffer any waste or damage,
disfigurement, or injury to the Premises or permit or suffer any overloading of
the floors of the Premises.

          20.  ADA.  During the construction of the Tenant Improvements
specified in paragraph 53 of this Lease, Tenant shall also alter and renovate
the Premises to meet the standards established under the provisions of the
Americans With Disabilities Act ("ADA"), and, for such alterations and
additions, Landlord will pay Tenant the sum of $38,000.00 ("ADA Payment"),
regardless of the actual cost of such alterations and renovations. During the
full term of this Lease, Tenant shall also promptly, at its expense (except for
the ADA Payment), comply with the requirements of the ADA applicable to the
Premises, to the construction of the Tenant Improvements, to all other
alterations of the Premises by Tenant and to Tenant's use of the Premises.

          21.  WAIVER OF REPAIR AND DEDUCT.  Tenant hereby waives any and all
rights it may have to make repairs at Landlord's expense or in lieu thereof to
vacate the Premises as provided in California Civil Code Section 1942 or any
other law, statute, or ordinance now or hereafter in effect; provided, however,
that such waiver does not constitute a waiver of any of Tenant's specific
self-help or setoff rights expressly set forth in this Lease.

          22.  COMPLIANCE WITH LAWS.  Tenant shall, at Tenant's sole cost and
expense, comply promptly with all laws, ordinances, orders, regulations, and
requirements of all federal, state, and local governmental agencies, and with
the reasonable recommendations of any insurer under any policies required under
this Lease, that may be applicable to the Premises or the use thereof; provided,
however, that: (a) Tenant shall not be obligated to make any repairs,
alterations or improvements to the Premises that are required by governmental
authorities pursuant to requirements that were in effect on the date of this
Lease to the extent that the Building was not in compliance with such
requirements on the date of this Lease, except for ADA requirements; and (b)
Tenant shall not be responsible for any matters for which Landlord is
responsible under paragraph 23 of this Lease. Landlord shall be responsible for
the costs of compliance described in subparagraphs (a) and (b) of this paragraph
22.  Tenant shall be obligated to make any repairs, alterations or improvements
to the Premises that are required by governmental



                                       - 14 -
<PAGE>

authorities to comply with requirements enacted after the day of this Lease;
provided, however, that, with respect to such requirements that apply generally
to buildings similar to the Building, (1) Tenant will be obligated to cause such
compliance to occur and to pay the cost of such compliance only to the extent
such the cost of such compliance is equal to or less than $25,000 in any
calendar year and (2) Landlord will be obligated to cause such compliance to
occur and to pay the cost of such compliance only to the extent that the cost of
such compliance is in excess of $25,000 per calendar year. If Landlord pays any
cost under subparagraph (2) of this paragraph 22, then monthly Base Rent shall
be increased thereafter by an amount equal to the monthly amortization of such
cost paid by Landlord, determined using an interest rate equal to the Reference
Rate and a period equal to the manufacturer's estimated useful life of the
improvement, alteration and/or replacement to which such cost relates.

          23.  HAZARDOUS MATERIALS.  Tenant agrees not to cause or permit the
presence, use, generation, release, discharge, storage, disposal, or
transportation of any Hazardous Materials (as defined below) on, under, in,
above, to, or from the Property other than presence, use, storage and
transportation which is both (a) required for and solely incidental to Tenant's
principal use and operation of the Premises, and (b) in strict compliance with
all applicable federal, state, and local laws, regulations, and orders (such
obligations of Tenant being referred to below as "Tenant's Environmental
Obligations"). For the purposes of this Lease the term "Hazardous Materials"
shall refer to any substances, materials, and wastes that are or become
regulated as hazardous or toxic substances under any applicable local, state, or
federal law, regulation, or order ("Environmental Laws"). Tenant shall
indemnify, defend, and hold Landlord harmless from and reimburse Landlord for
any breach of Tenant's Environmental Obligations and all of the following which
may result from such a breach: (1) any loss, cost, expense, claim, or liability
arising out of any investigation, reporting, monitoring, clean-up, containment,
removal, storage, or restoration work required by any applicable federal, state,
or local law, governmental agency, or political subdivision or prudent standards
of real estate ownership and management; and (2) any claims of third parties for
loss, injury, expense, or damage arising out of the presence, release, or
discharge of any Hazardous Materials on, under, in, above, to, or from the
Premises during the term of this Lease.

          Landlord shall indemnify, defend, and hold Tenant harmless from and
reimburse Tenant as to the presence, use, generation, release, discharge,
storage, disposal, or transportation of any Hazardous Materials on, under, in,
above, to, or from the Property prior to the Commencement Date, other than as a
result of the breach of Tenant's Environmental Obligations, and all of the
following which may result therefrom: (A) any loss, cost, expense, claim, or
liability arising out of any investigation, reporting, monitoring, clean-up,
containment, removal, storage, or restoration work required by any applicable
federal, state, or local law (which



                                       - 15 -
<PAGE>

requirements Landlord agrees to satisfy at its sole expense), governmental
agency, or political subdivision or prudent standards of real estate ownership
and management; and (B) any claims of third parties for loss, injury, expense,
or damage arising out of such presence, release, or discharge of any Hazardous
Materials on, under, in, above, to, or from the Premises ("Landlord's
Environmental Indemnity"). Landlord will deliver to Tenant, not later than the
date required by paragraph 59 of this Lease, an irrevocable Standby Letter of
Credit ("Letter of Credit") in the initial amount of $2,000,000, issued to
Tenant (but not its assigns) by The Development Bank of Singapore Ltd. (New York
Agency), or another bank of Landlord's selection which is reasonably
satisfactory to Tenant, as security for the performance of Landlord's
Environmental Indemnity.  Such Letter of Credit shall be in substantially the
form attached to this Lease as EXHIBIT E.


          If Landlord defaults at any time during the initial term in the
performance of Landlord's Environmental Indemnity and such default continues
uncured for 30 days after written notice to Landlord, Tenant may draw upon the
Letter of Credit for the full amount paid by Tenant to cure a breach of
Landlord's Environmental Indemnity. Landlord will, at Landlord's expense, keep
the Letter of Credit in effect in the initial amount, less such draws, until the
31st day after the end of the initial term of this Lease (or, if Hazardous
Materials as to which Landlord has indemnified the Tenant pursuant to this Lease
are present or have been used, generated, released, discharged, stored, disposed
of or transported on, in, above, to or from the Property during the initial term
of this Lease, then until such later date as (i) all governmental agencies
having jurisdiction under Environmental Laws make final determinations that all
of the proper actions have been taken or that no actions are required with
respect to such Hazardous Materials and such determinations have been delivered
to Tenant or (ii) a court having jurisdiction over such matters determines that
Landlord has no indemnification responsibilities to Tenant regarding such
Hazardous Materials under the terms of this Lease and all appeals or the time
periods therefor have been exhausted with no change in such determination);
provided, however, that Tenant may waive such requirement at any time by express
written notice.

          Tenant will have the right to draw on the Letter of Credit for the
then full amount of the Letter of Credit if Landlord fails to renew the Letter
of Credit in an amount equal to the original amount thereof, less any amounts
drawn by Tenant to date, and for a period equal to the shorter of (x) 1 year or
more or (y) the remaining portion of the period with respect to which Landlord
is required to maintain the Letter of Credit, if such period can be determined
with certainty, and accomplish such renewal and deliver the renewed Letter of
Credit to Tenant at least 15 days before any expiration date, time being of the
essence. If Tenant draws upon the Letter of Credit because Landlord has failed
to renew the Letter of Credit as required above, Tenant shall hold the proceeds
of such draw in a separate interest-



                                       - 16 -
<PAGE>

bearing account (in Tenant's name) of Tenant's choosing.  The proceeds and
interest in such account shall be paid to Tenant or Landlord as follows:

          (AA)  to Landlord, upon receipt by Tenant of a renewed Letter of
Credit conforming to the requirements of this Lease;

          (BB)  to Tenant, if and to the extent that Tenant would have been
entitled to draw upon the Letter of Credit if it had been renewed; and/or

          (CC)  to Landlord, if and when Landlord is no longer required to
provide the Letter of Credit under the terms of this Lease.

          Tenant agrees that, upon termination of Landlord's obligation to
provide the Letter of Credit, Tenant will surrender the Letter of Credit to
Landlord and will execute all such certificates as Landlord reasonably requests
in connection with the termination of the Letter of Credit.

          Landlord represents and warrants to Tenant that Landlord has no
knowledge of the presence of any Hazardous Materials on, in, or under the
Property in violation of an Environmental Law or of the escape, seepage,
leakage, spillage, discharge, deposit, disposal, emission or release of any
Hazardous Materials on, in, under or from the Premises in violation of an
Environmental Law, except if set forth in (a) that certain Environmental
Assessment for 21605 Plummer Street, Chatsworth (Symbolic II), prepared by
Rockwell, or (b) that certain draft soil and groundwater assessment report for
21415 and 21605 Plummer Street, Chatsworth, California, dated November 23, 1992,
prepared by Groundwater Technology, or (c) that certain letter prepared by
Clayton Environmental Consultants dated November 10, 1992 (collectively, the
"Environmental Assessments"). Tenant represents and warrants to Landlord that
Tenant has no knowledge of the presence of any Hazardous Materials on, in, or
under the Property in violation of an Environmental Law or of the escape,
seepage, leakage, spillage, discharge, deposit, disposal, emission or release of
any Hazardous Materials on, in, under or from the Premises in violation of an
Environmental Law, except if set forth in the Environmental Assessments.

          Tenant agrees to provide to Landlord, within 10 days of receipt, a
copy of any notice regarding violation of any Environmental Law on or about the
Premises arising out of Tenant's operations on the Premises, a copy of any
report required by an Environmental Law regarding violation of the Environmental
Law on or about the Premises arising out of Tenant's operations on the Premises
and a copy of any notice of the emission or release of Hazardous Materials in
violation of an Environmental Law or arising out of Tenant's operations on the
Premises. Each Party agrees to provide to the other, within 10 days of receipt,
a copy of all test reports and correspondence associated with the investigation,
monitoring and



                                       - 17 -
<PAGE>

remediation of soil and groundwater on, in or under the Property and a copy of
any notice regarding the presence of any Hazardous Materials on, in, or under
the Property or the escape, seepage, leakage, spillage, discharge, deposit,
disposal, emission or release of any Hazardous Materials on, in, under or from
the Property in violation of any Environmental Law.

          If  (aa) there is any Hazardous Material on, in, or under the Premises
in violation of an Environmental Law (other than those arising out of a breach
of Tenant's Environmental Obligations) and (bb) as a result thereof, there is,
in the reasonable opinion of Tenant, a danger of harm to the employees or
invitees of Tenant, and a governmental agency having jurisdiction orders Tenant
to vacate the Premises or any affected portion of the Premises and Tenant does
so, then all Base Rent, Impositions, Insurance Costs and other amounts due under
this Lease will abate from the date of such vacation, in proportion to the space
vacated, until the governmental agency which ordered the vacation rescinds or
terminates its order.   If such governmental order is not rescinded or
terminated within ninety (90) days after such vacation of all or part of the
Premises by Tenant, either Landlord or Tenant may, within 30 days after the
expiration of such 90 day period, terminate this Lease by written notice to the
other party.

          Tenant shall have the right during the term of this Lease to conduct
such environmental testing and monitoring of the Premises as Tenant deems
appropriate, including the installation of ground water monitoring wells and/or
such other testing and monitoring as might be included in a Phase II
environmental assessment. Such testing and monitoring shall be conducted in
accordance with applicable laws and regulations and only after not less than
thirty (30) days prior written notice to Landlord.

          The obligations of Landlord and Tenant under this paragraph shall
survive the assignment, termination or cancellation of this Lease.  The rights
of Landlord and Tenant under this paragraph shall be in addition to any other
rights and remedies which Landlord or Tenant may have against the Property, each
other or any other person under any other document or any Environmental Law.

          24.  ALTERATIONS.  Except for non-structural alterations costing less
than $25,000, Tenant shall not alter the Premises or any part of the Property
without the prior written consent of Landlord (which consent shall be given or
withheld in writing, shall not be unreasonably withheld and shall be deemed to
be not given if not given or withheld in writing within 10 days after a written
request for such consent has been received by Landlord from Tenant), which
consent may be granted upon the condition that such alterations be removed (and
the affected portion of the Premises restored), at Tenant's expense, at the
expiration or earlier termination of this Lease. Each written request for such
consent shall contain a paragraph to be



                                       - 18 -
<PAGE>

signed by Landlord indicating whether or not the alteration in question must be
removed by Tenant at the expiration or earlier termination of this Lease.

          25.  PROPERTY OF LANDLORD.   Unless otherwise provided in this Lease,
all repairs, improvements, changes, alterations, and building equipment and
machinery (other than Trade Fixtures, Tenant's telephone switch and equipment,
air compressors and auxiliary air conditioners) made or installed by Tenant
(collectively, "Alterations") shall immediately upon completion or installation
thereof be and become the property of Landlord without payment therefor by
Landlord.

          26.  DAMAGE OR DESTRUCTION.  Subject to the other provisions of this
Lease, if the Premises or any portion thereof becomes damaged or wholly or
partially untenantable because of fire, earthquake, act of God, the elements or
other casualty, Landlord shall repair such damage with and to the extent of the
insurance proceeds made available to Landlord for such purpose.  However, if in
Landlord's opinion such repairs cannot be made within one hundred eighty (180)
days, Landlord shall so notify Tenant in writing within thirty (30) days of the
date of such damage.  In such event, either Tenant or Landlord may terminate
this Lease within thirty (30) days after Landlord's notice.  Termination shall
be effected by written notice delivered to the other party within said thirty
(30) day period.  If this Lease is not so terminated, it shall remain in full
force and effect except that an abatement of Base Rent, Impositions, Insurance
Costs and other amounts due under this Lease shall be allowed Tenant for such
part of the Premises as shall be rendered unusable by Tenant in the conduct of
its business during the time such part is so unusable.

          27.  WAIVER.  Tenant hereby waives California Civil Code Sections
1932, 1933, 1941 and 1942, and the provisions of any other law now or hereafter
in effect that would relieve Tenant from any obligation to pay rent under this
Lease except to the extent expressly provided in this Lease.

          28.  CONDEMNATION.  If the Premises or any portion thereof is taken
under the power of eminent domain (hereinafter referred to as "Condemnation"),
this Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever occurs first. If more than 10% of
the floor area of the Premises is taken by Condemnation, then at Tenant's
option, exercisable only in writing and within ten (10) days after Landlord
shall have given Tenant written notice of such taking (or, in the absence of
such notice, within ten (10) days after the condemning authority shall have
taken possession), and provided that Tenant is not in default under this Lease,
Tenant may terminate this Lease as of the date the condemning authority takes
possession.  If Tenant does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the Basic Rent shall be




                                       - 19 -
<PAGE>

reduced in the proportion that the floor area of the portions of the Premises
taken bears to the total floor area of the Premises.

          29.  CONDEMNATION AWARD.  In the event any portion of the Premises is
taken by Condemnation, Landlord shall be entitled to and shall receive the total
award made in such Condemnation, which award Tenant hereby assigns to Landlord,
except that Tenant shall be entitled to receive such portion of the award as may
be specifically allocated in such proceedings to compensation for Tenant's Trade
Fixtures, for improvements paid for by Tenant and not reimbursed out of the
Tenant Improvement Allowance and for Tenant's relocation expenses.

          30.  RESTORATION.  If less than the entire Premises shall be taken by
Condemnation, and this Lease is not terminated pursuant to paragraph 28, with
the net amount of any award received by Landlord in any proceeding for physical
damage to the Premises after deducting all of Landlord's costs and expenses of
collection, including without limitation attorneys' fees, Landlord shall
promptly restore that portion of the Premises not so taken to a complete
architectural unit.

          31.  TENANT'S WORK.  All work done by Tenant, its agents and
contractors, in or about the Premises or the Property (hereinafter called the
"Work") shall be done in all cases subject to the following conditions, each of
which Tenant covenants to observe and perform:

               (a)  No Work involving any structural change and no Work
involving any alteration, restoration, or rebuilding costing more than $25,000
shall be undertaken until detailed plans and specifications have first been
submitted to and approved in writing by Landlord (which approval shall be given
or withheld in writing, shall not be unreasonably withheld and shall be deemed
to be not given if not given or withheld in writing within 10 days after a
written request for such approval has been received by Landlord from Tenant).

               (b)  No Work involving a cost, as reasonably estimated by Tenant,
of more than $25,000 shall be undertaken except under the supervision of an
architect or engineer approved in writing by Landlord (unless such requirement
is waived by Landlord in writing).

               (c)  All Work shall be (i) commenced only after Landlord has
received 10 days' prior notice of such Work or Landlord has approved such Work
and only after all required local and other governmental permits and
authorizations have been obtained, (ii) done in a good and workmanlike manner,
(iii) performed in compliance with the building and zoning laws and with all
other laws, ordinances, regulations, and requirements of all federal, state, and
local governmental agencies, and in accordance with the recommendations of any
insurer under any policies required by this Lease, and (iv) completed promptly
and



                                       - 20 -
<PAGE>

free of liens.  Approval of any Work by Landlord shall not imply or be construed
to indicate compliance with above requirements.

          32.  MECHANICS' LIENS.  Tenant shall not suffer or permit any
mechanics' or other liens (or claims thereof) to be filed against the Premises
(or Tenant's leasehold interest therein or hereunder) or the Property by reason
of work, labor, services, or materials supplied or claimed to have been supplied
to Tenant or anyone holding the Premises or any part thereof through or under
Tenant; provided, however, that Tenant shall have the right to contest any such
liens so long as Tenant provides Landlord with reasonable security (by bond,
escrow or otherwise) during such contest. Landlord shall have the right at all
reasonable times to post and keep posted on the Premises any notices that
Landlord may deem necessary or advisable for the protection of Landlord, the
Premises and the Property from mechanics' liens.  If any such liens (or claims
thereof) shall at any time be filed against the Premises or the Property, Tenant
shall contest the liens or claims as provided above or shall cause the same to
be discharged of record within forty-five (45) days after the date of filing.

          33.  FINANCIAL STATEMENTS.  Upon the request of Landlord, Tenant shall
provide to Landlord, at no expense to Landlord, copies of the most recent
quarterly and annual financial reports with respect to Tenant as have been made
available by Tenant to its shareholders.

          34.  LANDLORD'S ENTRY.  Tenant agrees to permit Landlord and any
authorized representatives of Landlord, upon reasonable prior notice to Tenant,
to enter the Premises with reasonable frequency during usual business hours, or
at any other time in case of emergency, (a) to inspect (which may include
environmental audits) the Premises and, if Landlord so desires, but without
implying any obligation of Landlord to do so, to make any repairs deemed
necessary or desirable by Landlord and to perform any work in the Premises
deemed necessary by Landlord to comply with any laws or the recommendations of
any insurer, and (b) during the final twelve months of the term of this Lease,
for the purpose of leasing the Premises, during which twelve-month period
Landlord may display on the Premises, in such manner as not to interfere
unreasonably with Tenant's business, usual "For Sale" or "To Let" signs.

          35.  ASSIGNMENT AND SUBLETTING.

               (a)  Tenant shall not, without the prior consent of Landlord
(which consent shall be given or withheld in writing, shall not be unreasonably
withheld and shall be deemed to be not given if not given or withheld in writing
within 10 days after a written request for such consent has been received by
Landlord from Tenant), assign this Lease or any interest herein, sublet the
Premises or any part thereof, or permit the use of the Premises by any party
other than Tenant.  This



                                       - 21 -
<PAGE>

Lease shall not, nor shall any interest herein, be assignable as to the interest
of Tenant by operation of law except as herein otherwise provided. Any of the
foregoing acts without such consent shall be void and shall, at the option of
Landlord, terminate this Lease.  In connection with each consent requested by
Tenant, Tenant shall submit to Landlord the terms of the proposed transaction,
the identity of the parties to the transaction, the proposed documentation for
the transaction, and all other information reasonably requested by Landlord
concerning the proposed transaction and the parties involved.


               (b)  If the Tenant is a privately held corporation, the transfer
(except pursuant to a public offering), assignment, or hypothecation of any
stock or interest in such corporation in excess of fifty percent (50%) in the
aggregate of the voting stock or interest in Tenant shall be deemed an
assignment or transfer within the meaning and provisions of this paragraph. If
Tenant is a publicly held corporation, the public offering or trading of stock
in Tenant shall not be deemed an assignment or transfer within the meaning of
this paragraph.

               (c)  Without limiting the other instances in which it may be
reasonable for Landlord to withhold its consent to an assignment or subletting,
Landlord and Tenant acknowledge that it shall be reasonable for Landlord to
withhold its consent in the following instances:

                    (1)  if at the time consent is requested or at any time
prior to the granting of consent, Tenant is in default under this Lease or would
be in default under this Lease but for the pendency of any grace or cure period
specified in this Lease; or

                    (2)  if the proposed assignee or sublessee is a governmental
agency; or

                    (3)  if, in Landlord's reasonable judgment, the use of the
Premises by the proposed assignee or sublessee would involve occupancy in
violation of this Lease.

               (d)  If at any time during the term of this Lease Tenant desires
to assign its interest in this Lease or sublet all or any part of the Premises,
Tenant shall give notice to Landlord setting forth the terms of the proposed
assignment or subletting ("Tenant's Request").  If the consummation of the
assignment or sublease would cause Tenant to occupy less than 50% of the
rentable area of the Premises, Landlord shall have the option, exercisable by
written notice given to Tenant within thirty (30) days after Tenant's Request is
given ("Landlord's Option Period"), either (1) to consent to the assignment
(which consent shall not be unreasonably withheld and shall be deemed to be not
given if not given or withheld in writing within such 30-day period), in which
event the provisions of subparagraph (g) shall be applicable,



                                       - 22 -
<PAGE>

or to consent to the subletting in which event the provisions of subparagraph
(h) shall be applicable; (2) to become the assignee or sublessee of Tenant
(instead of the entity specified in Tenant's Request) upon the terms set forth
in Tenant's Notice; (3) in the event of (A) a proposed assignment, or (B) a
proposed subletting of the entire Premises, or a portion of the Premises for all
or substantially all of the remainder of the term, to terminate this Lease with
respect to, and to retake possession of, the space in question, together with,
if only a portion of the Premises is involved, such rights of access to and from
such portion as may be reasonably required for its use and enjoyment. If the
foregoing sentence is applicable and Landlord does not exercise one of such
options, or if  Landlord consents or is deemed to consent to the proposed
assignment or sublease, Tenant shall be free for a period of one hundred twenty
(120) days after giving Tenant's Request, or one hundred twenty (120) days after
the date Landlord's consent (if such consent is required) is given to Tenant, or
one hundred twenty (120) days after the expiration of Landlord's Option Period
(if applicable), to assign its entire interest in this Lease or to sublet such
space to the entity specified in Tenant's Request upon the terms set forth
therein or to any third party upon the same terms set forth in Tenant's Request,
subject to obtaining Landlord's prior consent as hereinabove provided.

               (e)  Notwithstanding the provisions of subparagraphs (a) and (b)
above, Tenant may assign this Lease or sublet the Premises or any portion
thereof, with prior notice to Landlord but without the necessity of Landlord's
consent and without extending any option to Landlord pursuant to subparagraph
(d) above, to any corporation which controls, is controlled by or is under
common control with Tenant, or to any corporation resulting from the merger or
consolidation with Tenant ("Affiliate").

               (f)  No sublease, once consented to by Landlord, shall be
modified or terminated by Tenant without Landlord's prior consent (which consent
shall be given or withheld in writing, shall not be unreasonably withheld and
shall be deemed to be not given if not given or withheld in writing within 10
days after a written request for such consent has been received by Landlord from
Tenant).

               (g)  In the case of an assignment to an entity other than
Landlord or an Affiliate, 50% of all sums and other economic consideration
received by Tenant as a result of such assignment shall be paid to Landlord
after first deducting 50% of: (1) the unamortized cost of leasehold improvements
paid for by Tenant, (2) the cost of any concessions and inducements given to the
assignee by Tenant and (3) the cost of any real estate commissions and other
marketing costs incurred by Tenant in connection with such assignment.

               (h)  In the case of a subletting to an entity other than Landlord
or an Affiliate, 50% of all sums and economic consideration received by Tenant
as a result of such subletting shall be paid to Landlord after first deducting
50% of (1) the



                                       - 23 -
<PAGE>

rental due hereunder, prorated to reflect only rental allocable to the sublet
portion of the Premises, (2) the cost of leasehold improvements made to the
sublet portion of the Premises at Tenant's cost, amortized over the term of this
Lease except for leasehold improvements made for the specific benefit of the
sublessee, and the cost of any concessions and inducements given to the
subtenant by Tenant, all of which shall be amortized over the term of the
sublease, and (3) the cost of any real estate commissions and other marketing
costs incurred by Tenant in connection with such subletting, amortized over the
term of the sublease.

               (i)  Regardless of Landlord's consent, no subletting or
assignment (except to Landlord pursuant to the provisions of subparagraph (d)
above) shall release Tenant of Tenant's obligation or alter the primary
liability of Tenant to pay the rent and to perform all other obligations to be
performed by Tenant hereunder.  The acceptance of rent by Landlord from any
other person shall not be deemed to be a waiver by Landlord of any provision
hereof.  Consent to one assignment or subletting shall not be deemed consent to
any subsequent assignment or subletting.  In the event of default by any
assignee of Tenant or any successor of Tenant in the performance of any of the
terms hereof, Landlord may proceed directly against Tenant without the necessity
of exhausting remedies against such assignee or successor.  Landlord may consent
to subsequent assignments or subletting of this Lease or amendments or
modifications to this Lease with assignees of Tenant, without notifying Tenant,
or any successor of Tenant, and without obtaining its or their consent thereto,
and such action shall not relieve Tenant of liability under this Lease.

               (j)  In the event Tenant shall once request the consent of
Landlord to any assignment or subletting, then as to each request for consent to
a further assignment or subletting Tenant shall pay Landlord's then reasonable
and standard processing fee and Landlord's reasonable attorneys' fees incurred
in connection therewith; provided, however, that Tenant shall not be required to
pay Landlord in excess of $500 for Landlord's processing fee or attorney's fees
in connection with any such request.

               (k)  In the event of an assignment of this Lease by Tenant to an
Affiliate, if Tenant returns the Letter of Credit to Landlord and requests
Landlord to do so in writing, Landlord shall promptly cause the Letter of Credit
to be reissued in the name of the assignee as Beneficiary. In the event of any
other assignment of this Lease by Tenant, the Letter of Credit will not be
issued in the name of the assignee and the assignee will have no right to draw
upon or have the benefits of the Letter of Credit.

               (l)  If the initial Tenant assigns this Lease to an Affiliate and
does not request that the Letter of Credit be reissued in the name of the
Affiliate as Beneficiary pursuant to subparagraph 35(k) above, the Letter of
Credit shall be



                                       - 24 -
<PAGE>

maintained by Landlord as required by this Lease for the remainder of the
initial term of this Lease and the initial Tenant shall be entitled to draw upon
the Letter of Credit on its own behalf or on behalf of such Affiliate.

          36.  SUBORDINATION.  At Landlord's option, this Lease shall be
subordinate to any ground lease, mortgage, deed of trust, or any other
hypothecation or security now or hereafter placed upon the Premises and to any
and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements, and extensions thereof.
Notwithstanding such subordination, Tenant's right to a quiet possession of the
Premises shall not be disturbed if Tenant is not in default and so long as
Tenant shall pay the rent and observe and perform all of the provisions of this
Lease, unless this Lease is otherwise terminated pursuant to its terms. If any
mortgagee, trustee, or ground lessor shall elect to have this Lease prior to the
lien of its mortgage, deed of trust, or ground lease, and shall give written
notice thereof to Tenant, this Lease shall be deemed prior to such mortgage,
deed of trust, or ground lease, whether this Lease is dated prior or subsequent
to the date of such mortgage, deed of trust, or ground lease or the date of the
recording thereof.

          37.  ATTORNMENT.  In the event any proceedings are brought for the
foreclosure of, or in the event of exercise of the power of sale under, any
mortgage or deed of trust now or hereafter on the Premises or any part thereof,
Tenant shall, if so requested by the purchaser upon such foreclosure or sale or
the grantee under a deed in lieu of foreclosure, attorn to such purchaser or
grantee and recognize such purchaser or grantee as the Landlord under this
Lease.

          38.  INDEMNIFICATION.  Tenant agrees to indemnify, defend, and save
Landlord harmless from and to reimburse Landlord for any and all claims arising
from (a) the conduct or management of, or any work or thing whatsoever done by
or for Tenant in or about the Premises or the Property during the term of this
Lease, (b) any condition existing during the term of this Lease of (i) the
Premises, (ii) any street, curb, or sidewalk adjoining the Premises, or (iii)
any vaults, passageways, or spaces therein or appurtenant thereto, (c) any
breach or default on the part of Tenant in the performance of any covenant or
agreement on the part of Tenant to be performed pursuant to the terms of this
Lease, (d) any act or negligence of Tenant or any of its agents, contractors,
servants, employees, or licensees occurring about the Premises, (e) any
accident, injury, or damage whatsoever caused to any person, firm, or
corporation occurring during the term of this Lease in or about the Premises or
upon or under the sidewalks or the land adjacent thereto, and (f) any and all
costs, counsel fees, expenses, and liabilities reasonably incurred in connection
with the such claim or action or proceeding brought thereon, except to the
extent that any of the above-described claims arise out of the negligence or
willful misconduct of Landlord, in which case Landlord agrees to indemnify,
defend, and save Tenant harmless from and to reimburse Tenant for any and all
claims arising from such



                                       - 25 -
<PAGE>

negligence or wilful misconduct.  In case any action or proceedings be brought
against an indemnified party by reason of an indemnified claim, the indemnifying
party, upon notice from the indemnified party, covenants to resist or defend
such action or proceeding by counsel satisfactory to the indemnified party.

          39.  ATTORNEYS' FEES.  If any action arising out of this Lease is
brought by either party hereto against the other, then and in that event the
unsuccessful party to such action shall pay to the prevailing party all costs
and expenses, including reasonable attorneys' fees, incurred by such prevailing
party, and if the prevailing party shall recover judgment in such action, such
costs, expenses and attorneys' fees (at trial and on appeal) shall be included
in and as part of such judgment.

          40.  LANDLORD'S CORRECTION OF DEFECTS; REPRESENTATIONS. Tenant shall,
within 30 days after commencing construction of the Tenant Improvements, provide
Landlord with a written list of operating defects, if any, observed by Tenant in
the Building's systems or the portions of the Premises for which Landlord has
maintenance responsibility under paragraph 16 of this Lease. Landlord will, not
later than the Commencement Date (or such earlier date as may be reasonably
required by Tenant in order for Tenant to complete the Tenant Improvements on or
before the Commencement Date),  correct such defects. Except as otherwise
expressly provided in this Lease, Landlord has made no representations of any
nature whatsoever in connection with the condition of the Premises or the
Property or any part thereof, and Landlord shall not be liable for any defects
therein.

          41.  EVENTS OF DEFAULT.  The following events shall be deemed to be
events of default by Tenant under this Lease:

               (a)  The failure of Tenant to pay any installments of Base Rent
or additional rent when due, or any other payment or reimbursement to Landlord
required herein when due, where such failure shall continue for a period of five
(5) days after written notice of such failure.

               (b)  (i)  The application by Tenant for, or Tenant's consent to
the appointment of, a receiver, trustee, or liquidator of Tenant or of all or a
substantial part of Tenant's assets, (ii) the making by Tenant of any general
arrangement or assignment for the benefit of creditors, (iii) Tenant becoming a
"debtor" as defined in 11 U.S.C. Section 101 or any successor statute thereto
(unless, in the case of a petition filed against Tenant, the same is dismissed
within sixty (60) days), (iv) the appointment of a trustee or receiver to take
possession of all or substantially all of Tenant's assets located at the
Premises or of Tenant's interest in this Lease (unless possession is restored to
Tenant within ninety (90) days) or (v) the attachment, execution, or other
judicial seizure of all or substantially all of Tenant's



                                       - 26 -
<PAGE>

assets located at the Premises or of Tenant's interest in this Lease (unless
such seizure is discharged within ninety (90) days).

               (c)  Tenant shall fail to comply with any other term, provision,
or covenant of this Lease, where such failure shall continue for a period of
twenty (20) days after written notice thereof to Tenant, provided, however, that
if such failure cannot reasonably be cured within twenty (20) days, Tenant shall
not be deemed in default with respect to such failure if Tenant commences to
cure such default within said twenty (20) day period and thereafter diligently
and continuously prosecutes such cure to a prompt completion. In the event
Landlord serves Tenant with a "Notice to Perform or Quit" pursuant to applicable
unlawful detainer statutes, such notice shall also constitute the notice
required by this subparagraph, provided that such notice gives Tenant at least
twenty (20) days in which to perform or quit.

          42.  LANDLORD'S REMEDIES.  Upon the occurrence of any event of default
by Tenant, Landlord may, at its option and without any further notice or demand
(in addition to any other rights and remedies under this Lease, at law or in
equity) do any of the following:

               (a)  Landlord shall have the right, so long as such default
continues, to give notice of termination to Tenant.  On the date specified in
such notice (which shall not be less than three (3) days after the giving of
such notice) this Lease shall terminate.

               (b)  In the event of any such termination of this Lease, Landlord
may then or at any time thereafter re-enter the Premises and remove therefrom
all persons and property and again repossess and enjoy the Premises, without
prejudice to any other remedies that Landlord may have by reason of Tenant's
default or of such termination.

               (c)  The amount of damages that Landlord may recover in the event
of such termination shall include, without limitation:  (1) the amount at the
time of award (computed by discounting such amount at the discount rate of the
Federal Reserve Bank of San Francisco at the time of award plus one percent) of
(A) unpaid rent earned at the time of termination, (B) the amount by which the
unpaid rent that would have been earned during the period from termination until
the award exceeds the amount of such rent loss that Tenant proves could have
been reasonably avoided, and (C) the amount by which the unpaid rent for the
balance of the term after the time of award exceeds the amount of such rent loss
that Tenant proves could be reasonably avoided; (2) all legal expenses and other
related costs incurred by Landlord following Tenant's default; (3) all costs
incurred by Landlord in restoring the Premises to good order and condition, or,
to the extent reasonably necessary to accomplish such reletting, in remodeling,
renovating, or otherwise



                                       - 27 -
<PAGE>

preparing the Premises for reletting; and (4) all other costs (including without
limitation any brokerage commissions) incurred by Landlord in
reletting the Premises.

               (d)  Following the termination of this Lease (or upon Tenant's
failure to remove its personal property from the Premises after the expiration
of the term of this Lease), Landlord may remove any and all personal property
located in the Premises and sell or place such property in a public or private
warehouse or elsewhere at the sole cost and expense of Tenant in accordance with
applicable law. Tenant waives all claims for damages that may be caused by
Landlord's removing, storing, or selling the property as herein provided.

               (e)  Landlord shall have the right to cause a receiver to be
appointed in any action against Tenant to take possession of the Premises and to
collect the rents or profits derived therefrom.  The appointment of such
receiver shall not constitute an election on the part of Landlord to terminate
this Lease unless notice of such intention is given to Tenant.

               (f)  Landlord shall have the remedy described in California Civil
Code Section 1951.4 (i.e. Landlord may continue this Lease in effect after
Tenant's abandonment and recover rent as it becomes due, because Tenant has the
right to sublet or assign, subject only to reasonable limitations). Even though
Tenant has breached this Lease and abandoned the Premises, this Lease shall
continue in effect for so long as Landlord does not terminate Tenant's right to
possession, and Landlord may enforce all its rights and remedies under this
Lease, including the right to recover rent in periodic actions as it becomes due
under this Lease.  In such event, Landlord may re-enter the Premises and remove
all persons and property if the Premises have not been vacated, using any
available summary proceedings, without such re-entry or removal being deemed a
termination or acceptance of surrender of this Lease. Landlord may then elect to
relet the Premises for the account of Tenant for a period that may extend beyond
the term hereof, and upon such other terms as Landlord may reasonably deem
appropriate.  Tenant shall reimburse Landlord upon demand for all costs incurred
by Landlord in connection with such reletting, including without limitation
necessary restoration, renovation, or improvement costs, attorneys' fees, and
brokerage commissions.  The proceeds of such reletting shall be applied first to
any sums then due and payable to Landlord from Tenant, including the
reimbursement described above.  The balance, if any, shall be applied to the
payment of future rent as it becomes due hereunder.

          43.  TENANT'S SETOFF RIGHTS.  If (a) Landlord fails to perform any
repair or maintenance obligation of Landlord under this Lease, and fails to cure
such default within 30 days after receipt of notice of such default from Tenant
(or, if Landlord's repair or maintenance obligation cannot be reasonably
performed within 30 days, Landlord fails to commence to perform it within such
30-day period and to



                                       - 28 -
<PAGE>

thereafter diligently prosecute it to a prompt conclusion), or (b) Landlord
fails to pay Tenant the Tenant Improvement Allowance when required to do so
under this Lease, and fails to cure such default within one year after receipt
of notice of such default from Tenant, Tenant may cure such default and charge
the costs to Landlord (plus interest on such charges from the date the charges
are incurred by Tenant, at the Default Interest Rate), and may set off such
costs and interest, and/or any portion of the Tenant Improvement Allowance that
has not been made to Tenant by Landlord (plus interest on such portion from the
date it was due to Tenant, at the Default Interest Rate), against installments
of Base Rent due under this Lease; provided, however, that Tenant shall not
set-off against more than 25% of the Base Rent due in any month (but such
limitation shall not apply to the final 6 months of this Lease).  Tenant shall
be permitted to continue to set off against succeeding installments of Base Rent
due under this Lease until the total amount of such costs or payment and
interest thereon have been recovered by Tenant.

          44.  CUMULATIVE REMEDIES.  The specified remedies to which Landlord
may resort under the terms of this Lease are cumulative and are not intended to
be exclusive of any other remedies or means of redress to which Landlord may be
entitled, either at law or in equity, in case of any breach or threatened breach
by Tenant of any covenant, agreement, or condition of this Lease.

          45.  NO WAIVERS.  The failure of Landlord to insist in any one or more
instances upon the strict performance or observance of any of the covenants,
agreements, or conditions of this Lease or to exercise any option herein
contained shall not be construed as a waiver or a relinquishment of future
performance or observance of such covenant, agreement, or condition or exercise
of such option.

          46.  HOLDING OVER.  Tenant covenants that it will vacate the Premises
immediately upon the expiration or sooner termination of this Lease.  If, with
Landlord's consent, Tenant retains possession of the Premises or any part
thereof after the expiration or termination hereof, Tenant shall pay Landlord
200% of the Base Rent due under this Lease immediately before such expiration or
termination, for the time Tenant thus remains in possession.  The provisions of
this paragraph do not exclude Landlord's rights of re-entry or any other right
hereunder, including without limitation the right to refuse 200% Base Rent and
instead to remove Tenant through summary proceedings for holding over beyond the
expiration of the term of this Lease.

          47.  NOTICES.  All notices, demands, and requests that may or are
required to be given by either party to the other shall be in writing and shall
be deemed given when sent by United States Certified Mail, postage prepaid, (a)
if for Tenant, addressed to Tenant (Attn: Chief Financial Officer), prior to
Commencement Date at 9310 Topanga Canyon Boulevard, Chatsworth, California 91311
and after the Commencement Date at the address of the Premises, in either



                                       - 29 -
<PAGE>

case with a copy to ADC Telecommunications, Inc., 12501 Whitewater Drive,
Minnetonka, Minnesota 55343 (Attn: Chief Financial Officer and Attn: General
Counsel),  or at such other address or addresses as Tenant may from time to time
designate by written notice to Landlord, or (b) if for Landlord, addressed to
Landlord, c/o GSIC Realty Corporation, 255 Shoreline Drive, Suite 600, Redwood
City, California 94065 or at such other places as Landlord may from time to time
designate by written notice to Tenant.

          48.  LIMITATION OF LANDLORD'S LIABILITY.  In the event of a sale or
transfer by Landlord of its interest in the Premises or this Lease, such sale or
transfer shall operate to release the transferor from all liability for the
performance of the obligations of Landlord hereunder, expressed or implied, from
and after the date of such transfer, and Tenant agrees thereafter to look solely
to the successor in interest of Landlord in and to this Lease for the
performance of Landlord's obligations hereunder accruing after the date of such
transfer (including the return of the Security Deposit) and thereupon Landlord
shall be discharged from any further liability with respect thereto.

          49.  ESTOPPEL CERTIFICATES.  At any time and from time to time upon
not less than ten (10) days' prior request by Landlord, Tenant agrees to
execute, acknowledge, and deliver to Landlord a statement in writing certifying
(a) that this Lease is unmodified and in full force and effect (or if there have
been modifications, that the same is in full force and effect as modified and
identifying the modifications), (b) the dates to which Base Rent, Impositions,
Insurance Costs and other amounts due under this Lease have been paid, and (c)
whether there is then existing any claim by Tenant of default hereunder by
Landlord and, if so, specifying the nature thereof. It is intended that any such
statement may be relied upon by any person proposing to acquire Landlord's
interest in this Lease or any prospective mortgagee of, or assignee of any
mortgage upon, such interest. At any time and from time to time upon not less
than ten (10) days' prior request by Tenant, Landlord agrees to execute,
acknowledge, and deliver to Tenant a statement in writing certifying (a) that
this Lease is unmodified and in full force and effect (or if there have been
modifications, that the same is in full force and effect as modified and
identifying the modifications), (b) the dates to which Base Rent, Impositions,
Insurance Costs and other amounts due under this Lease have been paid, and (c)
whether there is then existing any claim by Landlord of default hereunder by
Tenant and, if so, specifying the nature thereof. It is intended that any such
statement by Landlord may be relied upon by any person proposing to receive a
mortgage or assignment of Tenant's interest in this Lease or to enter into any
sublease of all or part of the Premises.

          50.  BROKERAGE.  Each party represents and warrants to the other that
it has not dealt with any broker, agent, or other person in connection with this
transaction and that no other broker, agent, or other person brought about this



                                       - 30 -
<PAGE>

transaction through it, other than CB Commercial Real Estate, Mel Goldstein, Bob
Shafer, The Johnston Group and Cal Johnston (whose commissions shall be paid by
Landlord), and each party agrees to indemnify and hold the other party harmless
from and to reimburse the other party for any and all claims by any other
broker, agent, or person claiming a commission or other form of compensation by
virtue of having dealt with it with respect to this leasing transaction.  The
provisions of this paragraph shall survive the termination of this Lease.

          51.  SECURITY DEPOSIT.  Tenant shall, upon execution of this Lease,
deposit with Landlord the sum of $77,000.00 as security for the full and
faithful performance of every provision of this Lease to be performed by Tenant
during the full term of this Lease (the "Security Deposit").  If Tenant defaults
with respect to any provision of this Lease during the term of this Lease and
such default continues beyond the applicable grace period, Landlord may use,
apply, or retain all or any part of the Security Deposit for the payment of Base
Rent or any other sum in default, for the payment of any other amount that
Landlord may spend or become obligated to spend by reason of Tenant's default,
or to compensate Landlord for any other loss, cost, or damage that Landlord may
suffer by reason of Tenant's default. If any portion of the Security Deposit is
so used or applied, Tenant shall, within five (5) days after written demand
therefor, deposit cash with Landlord in an amount sufficient to restore the
Security Deposit to its original amount. Landlord shall not be required to keep
the Security Deposit separate from its general funds and Tenant shall not be
entitled to interest on such deposit. Landlord shall refund the Security Deposit
to Tenant within 10 days after the expiration of the term of this Lease. If (a)
Tenant has reasonable grounds, valid as of a date not more than 30 days prior to
the date that the final full monthly Base Rent payment is due under this Lease,
to believe that the then Landlord is unlikely to be in a financial position to
return the Security Deposit during the required refund period (the then pendency
of bankruptcy proceedings with regard to such Landlord or any general partner
thereof being absolute and unrebuttable evidence of reasonable grounds for such
belief), and/or (b) the then Landlord is a successor to the initial Landlord
under this Lease and has failed to enter into a written agreement running to the
benefit of and enforceable by Tenant whereby the then Landlord unconditionally
assumes all of the Landlord's obligations under this Lease with respect to the
Security Deposit or an original copy of such agreement has not been delivered to
Tenant (provided, however, that the then Landlord may in the alternative provide
Tenant with an opinion of counsel reasonably satisfactory to Tenant that, under
California law then in effect, Tenant shall have the same rights with respect to
the then Landlord without such a written agreement that it would have had if
such a written agreement were executed and delivered to Tenant) and/or (c) if
Landlord is a lender who shall have acquired title to the Premises without
personal obligation to refund the Security Deposit to Tenant within the required
refund period, Tenant shall give notice of such fact(s) to Landlord on or before
the date 15 days prior to the date that the final full monthly Base Rent payment
is due under this Lease. If Landlord



                                       - 31 -
<PAGE>

receives such notice and does not, prior to the date 5 days before the date that
the final full monthly Base Rent payment is due under this Lease, (i) if
subparagraph (a) above applies, provide Tenant with reasonable security for the
performance of Landlord's obligation to refund the Security Deposit and/or (ii)
if subparagraph (b) above applies, provide Tenant with the written agreement or
opinion described in such subparagraph (b) and/or (iii) if subparagraph (c)
above applies, provide to Tenant the lender-Landlord's written personal
commitment to Tenant to refund the Security Deposit during the required refund
period, Tenant may setoff such Security Deposit against the payment of Base Rent
and any other sums due Landlord under this Lease that are due on such payment
date or any subsequent date.

          52.  SIGNAGE.  Tenant shall not place or permit on the exterior or
roof of the Premises or on the balance of the real property constituting the
Premises or on the balance of the Property any sign, advertisement,
illumination, projection, or similar thing (a "Sign"), unless (a) Landlord has
given its prior written consent thereto (which consent shall be given or
withheld in writing, shall not be unreasonably withheld and shall be deemed to
be not given if not given or withheld in writing within 10 days after a written
request for such consent has been received by Landlord from Tenant), and (b)
such Sign complies with applicable law.  Subject to the foregoing, Tenant may
place a monument sign in front of the Premises, Tenant may place a directional
delivery sign at the delivery driveway shown on the attached EXHIBIT A, and may
place a sign or signs on the exterior of the Premises.

          53.  TENANT IMPROVEMENTS.

               (a)  Tenant shall construct the improvements to the Premises
described on the attached EXHIBIT C (collectively, the "Tenant Improvements").
Tenant shall promptly commence the work for Tenant Improvements and shall
diligently pursue such work to completion, as described in subparagraph (e)
below.

               (b)  Tenant shall submit to Landlord complete, finished drawings
and specifications (the "Plans") for the Tenant Improvements.  The Plans shall
be subject to Landlord's approval (which approval shall be given or withheld in
writing, shall not be unreasonably withheld and shall be deemed to be not given
if not given or withheld in writing within 10 days after a written request for
such approval has been received by Landlord from Tenant). Within ten (10)
business days after its receipt of the Plans, Landlord shall notify Tenant of
its approval or disapproval of the Plans, and if Landlord disapproves the Plans,
the revisions that Landlord requires in order to obtain such approval.  Tenant
and Tenant's architect or engineer shall meet with Landlord and its agents
within a reasonable period of time after any request for such meeting by
Landlord to answer questions or provide additional information with respect to
the Plans.  As promptly as reasonably possible thereafter, Tenant shall submit
to Landlord modified Plans incorporating the revisions required by Landlord.
The modified Plans shall be subject to



                                       - 32 -
<PAGE>

Landlord's approval (which approval shall be given or withheld in writing, shall
not be unreasonably withheld and shall be deemed to be not given if not given or
withheld in writing within 10 days after a written request for such approval has
been received by Landlord from Tenant).  The final Plans and specifications
approved by Landlord are hereinafter referred to as the "Final Plans."  If
appropriate, Tenant shall cause two sets of reproducible Final Plans, marked for
pricing and construction to be delivered to Landlord within 5 days after
Landlord's approval of the Final Plans.  Tenant shall engage an architectural
firm, duly licensed in the State of California, for preparation of the Plans and
supervision of the construction of the Tenant Improvements. Such firm shall be
subject to Landlord's approval (which approval shall be given or withheld in
writing, shall not be unreasonably withheld and shall be deemed to be not given
if not given or withheld in writing within 10 days after a written request for
such approval has been received by Landlord from Tenant).  Tenant shall not
commence any work in the Premises until Landlord has finally approved the Plans
(which approval shall be given or withheld in writing, shall not be unreasonably
withheld and shall be deemed to be not given if not given or withheld in writing
within 10 days after a written request for such approval has been received by
Landlord from Tenant).

               (c)  Tenant shall pay all the Tenant Improvement Costs (as
defined below) and, provided there are no events of default by Tenant, Landlord
will provide the Tenant Improvement Allowance specified in subparagraph (e)
below. Tenant Improvement Costs shall include, but not be limited to, the cost
of the work described on the attached EXHIBIT C to the extent included in the
Final Plans, and the following with respect to the Final Plans: hard costs of
construction (including builder's risk insurance and the Performance and Payment
Bonds hereinafter specified), permitting fees and the fees of Tenant's architect
and engineer, and of Tenant's construction manager, if any. Tenant Improvement
Costs shall not include any of Tenant's equipment or other personal property or
trade fixtures.

               (d)  Tenant shall employ a general contractor for the Tenant
Improvements duly licensed in the State of California and approved by Landlord
(which approval shall be given or withheld in writing, shall not be unreasonably
withheld and shall be deemed to be not given if not given or withheld in writing
within 10 days after a written request for such approval has been received by
Landlord from Tenant). Upon request by Landlord, Tenant shall deliver to
Landlord a copy of the construction contract entered into by Tenant and the
general contractor.  Before any work commences, the general contractor shall
obtain and deliver to Landlord Performance and Payment Bonds in form and amount
approved by Landlord (which approval shall be given or withheld in writing,
shall not be unreasonably withheld and shall be deemed to be not given if not
given or withheld in writing within 10 days after a written request for such
approval has been received by Landlord from Tenant). Such Bonds shall name
Landlord as the



                                       - 33 -
<PAGE>

obligee and shall be written by surety companies which have been approved by
Landlord (which approval shall be given or withheld in writing, shall not be
unreasonably withheld and shall be deemed to be not given if not given or
withheld in writing within 10 days after a written request for such approval has
been received by Landlord from Tenant) and are either on the United States
Department of the Treasury's list of sureties acceptable to the United States
Government or have at least a BB+ rating by Bests.  The Tenant Improvements
shall be constructed in a good and workmanlike manner and shall comply with all
laws, codes and ordinances applicable to the Premises.  Not less than five (5)
days prior to the date Tenant desires to commence the Tenant Improvements,
Tenant shall give written notice to Landlord setting forth or accompanied by all
of the following:

                    (i)       A description and schedule for the work to be
performed;

                    (ii)      The names and addresses of all contractors,
subcontractors and material suppliers who have then been engaged to construct or
supply the Tenant Improvements;

                    (iii)     Copies of all licenses and permits which may be
required in connection with the Tenant Improvements and which can then be
obtained; and

                    (iv)      Certificates of builder's risk insurance
reasonably satisfactory to Landlord.

As additional rent under this Lease, Tenant shall make, at its expense, any
repairs to the Premises and any corrections to the Tenant Improvements, the need
for which arise from the actions or omissions of anyone constructing the Tenant
Improvements.  During the progress of the work to be done by Tenant, such work
shall be subject to inspection by representatives of Landlord who shall be
permitted access and the opportunity to inspect, at all reasonable times upon
reasonable advance notice, in compliance with any safety and work rules then
imposed at the Premises by Tenant or its contractors, but this provision shall
not in any way whatsoever create any obligation on Landlord to conduct any such
inspection.

               (e)  Upon completion of the Tenant Improvements in accordance
with the Final Plans and the requirements of the ADA, Landlord shall pay to
Tenant an amount (the "Tenant Improvement Allowance") equal to the sum of (1)
the lesser of the Tenant Improvement Costs or $600,000, plus (2) the ADA
Payment, upon receipt of all of the following: (i) unconditional lien waivers
from all contractors, subcontractors and suppliers of materials and equipment,
(ii) an affidavit executed by the general contractor certifying the cost of the
Tenant Improvements and stating that it has delivered to Landlord lien waivers
from all



                                       - 34 -
<PAGE>

subcontractors and suppliers and that the contractor has paid all debts or
settled all claims for labor and materials in connection with the Tenant
Improvements, (iii) an affidavit executed by Tenant that it accepts and is
satisfied with the Tenant Improvements and that all contractors and suppliers in
connection with the Tenant Improvements have been paid, (iv) a certification of
completion executed by the Tenant's architect confirming that the Tenant
Improvements have been completed in accordance with the Final Plans and that, if
required, a Certificate of Occupancy (temporary or permanent) has been issued
with respect to the Premises by the local authority having jurisdiction thereof,
and (v) if required by Landlord, a complete set of "as-built" plans and
specifications for the Tenant Improvements.  The Tenant Improvements shall be
deemed completed upon satisfaction of all of the foregoing. Tenant's obligation
to pay the rent under this Lease shall not be postponed due to delay of any
nature, however arising, in completion of the Tenant Improvements, except for
delays caused by Landlord's failure to perform its repair and maintenance
obligations under paragraphs 16 and 40 of this Lease, in which case the
Commencement Date shall, at Tenant's option to be exercised by written notice to
Landlord, be extended by the number of days of delay so caused by Landlord.

               (f)  Tenant agrees to expend at least $400,000 in excess of the
Tenant Improvement Allowance for the Tenant Improvements, including costs of
Tenant's internal space planners and internal environmental review.

          54.  OPTIONS TO EXTEND TERM.  Tenant shall have two options
(collectively the "Options" and individually an "Option") to extend the term of
this Lease for two additional consecutive six (6) year periods, the first of
which shall commence on the expiration of the initial term of this Lease (the
"First Renewal Option") and the second of which shall commence six (6) years
thereafter (the "Second Renewal Option"), provided that:

               (a)  The First Renewal Option shall be exercised by written
notice of exercise delivered to Landlord no later than nine (9) months before
the expiration of the initial term of this Lease, and the Second Renewal Option
shall be exercised by written notice of exercise delivered to Landlord no later
than nine (9) months before the expiration of the term of the First Renewal
Option.  If Tenant fails to so exercise the First Renewal Option, both of the
Options shall terminate.  If Tenant so exercises the First Renewal Option but
fails to so exercise the Second Renewal Option, the Second Renewal Option shall
terminate;

               (b)  At the time each Option is exercised and at the commencement
of the term of each Option, this Lease must be in full force and effect and
Tenant must not then be in default under this Lease. The foregoing conditions
are for the benefit of and may be waived by Landlord; and



                                       - 35 -
<PAGE>

               (c)  All of the terms, covenants and conditions of this Lease
shall remain in effect during the term of each Option except that (i) the Base
Rent commencing with the first day of the first month for each month of the
first thirty-six (36) months of the First Renewal Option shall be increased
based upon the percentage increase in the Consumer Price Index as such Index for
the 37th month of the initial term of this Lease bears to such Index for the
last month of the initial term; provided, however, that in no event shall the
Base Rent commencing with the first month of such term be more than 115% or less
than 109% of the Base Rent payable for the last month of the initial term of
this Lease; and (ii) commencing with the first day of the 37th month of the term
of the First Renewal Option, the Base Rent shall be increased based upon the
percentage increase in the Consumer Price Index as such Index for the 36th month
of such term bears to such Index for the last month of the initial term;
provided, however, that in no event shall the Base Rent commencing with the 37th
month of such term be more than 115% or less than 109% of the Base Rent payable
for the 36th month of the term of the First Renewal Option, and (iii) the Base
Rent for each month of the term of the Second Renewal Option shall be the Market
Rent for the Premises for the term of the Second Renewal Option (determined by
Appraisal if the parties cannot agree upon the Market Rent within 30 days after
Tenant's exercise of the Second Renewal Option); except that commencing with the
first day of the 37th month of the term of the Second Renewal Option, the Base
Rent shall be increased based upon the percentage increase in the Consumer Price
Index as such Index for the 36th month of such term bears to such Index for the
last month of the term of the First Renewal Option; provided, however, that in
no event shall the Base Rent commencing with the 37th month of such term be more
than 115% or less than 109% of the Base Rent payable for the 36th month of the
term of the Second Renewal Option.

          55.  EXPANSION SPACE.  Rockwell presently occupies that portion of the
Property commonly known as 21605 Plummer Street (the "Rockwell Building") which
contains approximately 130,572 rentable square feet of space. Rockwell has the
right to park 410 cars in the Rockwell Area. The term of the lease agreement for
the Rockwell Building expires on June 30, 1997, but Rockwell has the option to
cancel on one-year's prior written notice.  If Rockwell cancels its tenancy and
Landlord determines not to grant Rockwell rights to occupy the Rockwell Building
(or any portion thereof in excess of 105,000 square feet of rentable area) on
some basis, then, subject to the terms of this paragraph, Tenant shall have one
option (the "Expansion Option") to add to the Premises demised under this Lease,
the "Expansion Space" which shall be (i) the Rockwell Building, or (ii) a
portion thereof which shall consist of not less than 25,000 rentable square feet
and shall be configured (as mutually agreed upon by Landlord and Tenant in
writing) in such a manner as to meet Tenant's reasonable requirements and
applicable codes and any reasonable objections of Landlord set forth in written
notice to Tenant within ten (10) days after Landlord's receipt of Tenant's
Notice (as hereinafter defined), as follows:



                                       - 36 -
<PAGE>

               (a)  Tenant agrees to accept the Expansion Space in its "as is"
condition on the Availability Date (hereinafter defined) except as in this
paragraph otherwise provided;

               (b)  Landlord shall give Tenant written notice ("Landlord's
Notice") of the date upon which the Expansion Space shall be available (the
"Availability Date") and of the location and size of the Expansion Space. Tenant
shall have one option to have the Expansion Space added to the Premises demised
under this Lease on the Availability Date upon all the terms, covenants and
conditions contained in this Lease except that (i) the Base Rent for the
Expansion Space for the balance of the term of this Lease shall be Market Rent
with an $8.00 per net rentable square foot improvement allowance and without
reduction for the cost of creating all demising walls and related improvements
necessary for the Expansion Space to function separately from the remainder of
the Rockwell Building, which demising walls and related improvements Tenant
shall cause to be constructed and the costs of which shall be paid one-half by
Tenant and one-half by Landlord (which improvement allowance and other Landlord
reimbursements shall be paid to Tenant in accordance with disbursing procedures
similar to those provided for in paragraph 53 of this Lease), (ii) Tenant shall
be permitted to take occupancy of the Expansion Space on the Availability Date
in order to construct improvements therein, subject to each and every provision
of this Lease except that Tenant shall not be obligated to pay Base Rent with
respect to the Expansion Space until the "Rent Start Date" (defined below), and
(iii) the Rent Start Date shall be the 180th day after the Availability Date or
the date Tenant substantially completes its improvements in and occupies the
Expansion Space for business purposes, whichever is the earlier;

               (c)  The Expansion Option shall be exercised, if at all, by
written notice ("Tenant's Notice") of exercise given to Landlord not later than
twenty (20) days after Tenant's receipt of the Landlord's Notice.  If Tenant
fails to so exercise the Expansion Option it shall terminate;

               (d)  If Landlord and Tenant cannot agree upon the determination
of Market Rent on or before the date that Tenant is required to give Landlord
Tenant's Notice, and Tenant nonetheless elects to give Tenant's Notice, the
determination of Market Rent as to such Expansion Space will be submitted to
Appraisal in accordance with attached EXHIBIT D.  If on the date Base Rent as to
such Expansion Space is scheduled to commence pursuant to this Lease the
Appraisal has not been completed, Tenant will pay Base Rent based on Landlord's
reasonable estimate of Market Rent.  Upon determination of Market Rent by
Appraisal, Landlord will pay to Tenant or Tenant will pay to Landlord, as
appropriate, the amount equal to the overpayment or underpayment of Base Rent
from such commencement until the determination of Market Rent by Appraisal,
together with interest accrued thereon during such period at the Default
Interest Rate. Upon



                                       - 37 -
<PAGE>

establishment of the Base Rent for the Expansion Space, the parties agree to
execute an appropriate amendment to this Lease to reflect, as of the
Availability Date (i) the increase in the net rentable area of the Premises,
(ii) the increase in the Base Rent, and (iii) the increased Tenant's
Proportionate Share;

               (e)  As conditions precedent to Tenant's right to the Expansion
Option, at the time the Expansion Option is exercised and on the Availability
Date, this Lease must be in full force and effect, Tenant must not then be in
default thereunder and Tenant's interest under this Lease must not have been
assigned by operation of law or otherwise (except pursuant to an assignment with
respect to which Landlord has agreed in this Lease to give its consent or as to
which Landlord's consent is not required under this Lease). The foregoing
conditions are for the benefit of and may be waived by Landlord; and

               (f)  Landlord shall not be liable to Tenant for any loss or
damage for any failure to deliver possession of the Expansion Space to Tenant by
reason of the holding over or retention of possession by a tenant or occupant of
the Expansion Space and no such failure shall impair the validity of this Lease
or extend its term. Landlord will, however, exert reasonable efforts (including
legal proceedings to the full extent permitted under applicable laws) to cause
the other tenant to deliver possession of the Expansion Space.

               (g)  Tenant shall have the right to receive additional parking
with respect to the Expansion Space, at no cost to Tenant, as provided in
paragraph 4 of this Lease.

          56.  RIGHTS OF FIRST OFFER.  Tenant will have rights of first offer to
lease additional space in the Rockwell Building in accordance with the following
provisions:

               (a)  ANNUAL NOTICES.  No earlier than August 1 and no later than
October 1 of each calendar year during the term, Landlord will notify Tenant in
writing ("Annual Notice") of any rentable space within the Rockwell Building
that Landlord does not intend to warehouse, use or occupy and that is then
unleased or that will become unleased during the following calendar year in the
absence of the exercise of a Superior Right (as defined below).  The Annual
Notice will include the following:

               (1)  identification of the configurations of such space that
                    Landlord intends to use in marketing such space
                    "Configurations");

               (2)  the date on which each such Configuration that is then
                    leased will become unleased if no Superior Right (as defined
                    below) is exercised;



                                       - 38 -
<PAGE>

               (3)  identification of the rights of other tenants in the
                    Rockwell Building to lease any such Configuration pursuant
                    to right of first offer, right of first refusal, renewal,
                    extension or expansion provisions in their leases ("Superior
                    Rights"), together with identification of the date on which
                    each such Superior Right terminates; and

               (4)  Landlord's reasonable determination of Market Rent as to
                    each Configuration.

Landlord will not be required to give an Annual Notice (or any Interim Notices
or Reconfiguration Notices, as provided below, as to the calendar year to be
covered by the Annual Notice) unless, on or before July 1 of the year in which
such Annual Notice is to be given, Tenant has notified Landlord in writing of
Tenant's request that Landlord do so.

               (b)  INTERIM NOTICES.  If any rentable space within the Rockwell
Building that was not required to be included in the previous Annual Notice,
subject to the exercise of a Superior Right, becomes unleased during the
calendar year following the date that the previous Annual Notice was given to
Tenant, Landlord will notify Tenant in writing ("Interim Notice") of such fact
within 20 days after Landlord first has knowledge of such fact.  The Interim
Notice will include the following:

               (1)  the Configurations for such space;

               (2)  the date on which each such Configuration that is then
                    leased will become unleased if no Superior Right is
                    exercised;

            (3)     identification of each Superior Right applicable to each
                    such Configuration and the date on which each such Superior
                    Right terminates; and

            (4)     Landlord's reasonable determination of Market Rent as to
                    each Configuration.

               (c)  RECONFIGURATION NOTICES.  If Tenant has failed to exercise
its rights of first offer with respect to a particular Configuration identified
in an Annual Notice, as provided in this paragraph, and if Landlord subsequently
reconfigures such Configuration so that the area of such Configuration increases
or decreases by 20% or more, Landlord will, prior to such reconfiguration,
notify Tenant of such reconfiguration ("Reconfiguration Notice").  The
Reconfiguration Notice will include the following:



                                       - 39 -
<PAGE>

               (1)  the new Configurations resulting from such reconfiguration;

               (2)  the date on which each such new Configuration that is then
                    leased will become unleased if no Superior Right is
                    exercised;

               (3)  identification of each Superior Right applicable to each
                    such new Configuration and the date on which each such
                    Superior Right terminates; and

               (1)  Tenant's election to lease such Configuration must be made,
                    if at all, by written notice to Landlord ("Election Notice")
                    not later than (A) the November 1 following an Annual Notice
                    and (B) 15 days after an Interim Notice or Reconfiguration
                    Notice is given to Tenant. Tenant will be deemed to have
                    elected not to lease such Configuration if the Election
                    Notice is not given to Landlord within the applicable
                    response period.

               (2)  Tenant must have first elected to lease all Configurations
                    that are then unleased before Tenant may elect to lease any
                    Configurations that are then leased.

               (3)  Tenant may not elect to lease any space under this paragraph
                    during the last two years of the initial term of this Lease
                    or any Extended Term, unless Tenant has then exercised its
                    next available option to extend the term of this Lease.

               (e)  SUPERIOR RIGHTS.  Any election by Tenant to lease a
                    Configuration will be subject to the rights of other
                    tenants having applicable Superior Rights as identified
                    in the Annual Notice, Interim Notice or Reconfiguration
                    Notice.

rights of others.

          (g)  RENT. Base Rent for any space added to the Premises under this
paragraph will be equal to the Market Rent, determined as of the date of the
commencement of the term of this Lease with respect to such space.  If Landlord
and Tenant cannot agree upon the determination of Market Rent on or before the
date that Tenant is required to give Landlord an Election Notice, and Tenant
nonetheless elects to lease such space, the determination of Market Rent as to
such space will be submitted to Appraisal in accordance with attached EXHIBIT D.

this Lease the Appraisal has not been completed, Tenant will pay Base Rent based
on Landlord's reasonable estimate of Market Rent.  Upon determination of Market
Rent by Appraisal, Landlord will pay to Tenant or Tenant will pay to Landlord,

this Lease and to any Memorandum of Lease adding to the Premises any space which
Tenant has elected to lease pursuant to this paragraph, as of the commencement
date specified in this paragraph with respect to such space, and upon the terms
and conditions of this Lease.

          (j)  EFFECT OF DEFAULT.  If any default exists by Tenant under this
Lease that has not been cured or is being cured by Tenant within the applicable
grace period at the time the Election Notice is given or at the commencement of
the term of this Lease as to the space in question, Tenant will have no right to
exercise its option as to the applicable space and/or to lease such space.

          The time limitations with respect to Tenant's election to lease space
under this paragraph set forth in subparagraph (d) above and the condition set
forth in subparagraph (j) above are solely for the benefit of Landlord, and
Landlord may at its option waive any such limitation or condition.

not to interfere with the timely completion of improvements to be constructed in
such space by Tenant.

          58.  ROOF ANTENNAS.  Subject to the terms of paragraph 31 of this
Lease, Tenant may install on the roof of the Premises antenna and satellite

communications or other equipment in any adjoining structure, or (b) any
electronic control system or elevators in any adjoining structure, or (c) any
other transmitting, receiving or master TV antenna on any adjoining structure.

          59.  CONTINGENCIES.  Tenant's obligations under this Lease shall be
contingent upon the following occurring or being satisfied on or before the

and Tenant agree to execute).

          Tenant may waive such contingencies by written notice given to

a party to execute such a document will not affect the termination, and in such
event the party requesting the document may execute and file an affidavit
setting forth the date of termination.  The party requesting the execution of
such document will bear all costs thereof, including any recording fees.

          61.  MISCELLANEOUS.  This Lease cannot be changed orally, but only by
agreement in writing signed by the party against whom, or against whose
successors and assigns, enforcement of the change is sought.  The voluntary or
other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall
not work a merger as to any existing subtenancies and shall, at the option of

option, operate as an assignment to it of any and all such subtenancies.  The
words "Landlord" and "Tenant" as used herein shall include the plural as well as
the singular.  If there is more than one tenant, the obligations hereunder
imposed upon the Tenant shall be joint and several.  Time is of the essence of
this Lease and each and all of its provisions.  This Lease shall be construed
and enforced in accordance with the laws of the State of California.  The term
"Default Interest Rate" shall mean an annual rate equal to the reference or
prime rate of Bank of America ("Reference Rate"), or the successor to such rate,

thereof to any person, firm, corporation, or circumstance is or becomes to any
extent invalid or unenforceable, the remainder of this Lease, or the application
of such covenant, agreement, or condition to persons, firms, corporations, or
circumstances other than.those as to which it is invalid or unenforceable, shall
not be affected thereby, and in lieu of each clause or provision of this Lease
that is illegal, invalid, or unenforceable, there shall be added as a part of
this Lease a clause or provision as



                                       - 43 -
<PAGE>

similar in terms to such clause or provision as is possible and as may be legal,
valid, and enforceable.  If any excavation or other building operation shall be
made, or is about to be made, upon any adjoining property or streets, upon the
request of Landlord, Tenant shall permit the owner or lessee of such adjoining
property and their respective representatives to enter the Premises and shore
the foundations and walls thereof, and to do any other act or thing reasonably
necessary, in Landlord's opinion, for the safety or preservation of the
Premises.  Landlord's acceptance of a partial rent payment shall not constitute
a waiver of any rights of Tenant or Landlord, including, without limitation, any
right Landlord may have to recover possession of the Premises, in unlawful
detainer, or otherwise.  The parties agree that, except as in this Lease
otherwise provided, and subject to the provisions of paragraph 35 of this Lease,
the covenants and agreements herein contained shall bind and inure to the
benefit of the successors and assigns of the parties.

          Exhibits A through F are attached hereto and become part of
this Lease.

                              APPRAISAL PROCEDURES


          The parties to this Lease will initially attempt to agree upon the
Market Rent.  If they have been unable to so agree within the period that they
are required to agree as to such matter under the Lease,  then either party may
request by written notice to the other party ("Appraisal Request") that the
matter be determined by an appraisal board consisting of three appraisers who
are members of the Appraisers Institute (or a successor or similar organization,
if such organization no longer exists) and have at least five (5) years'
experience appraising commercial real estate in the Chatsworth, California area.
One appraiser will be appointed by each party, and each such appraiser will have
no material financial or other business interest in common with the party
selecting such appraiser.  If a party fails to appoint an appraiser and notify
the other party of such appointment within 30 days after the Appraisal Request
is made, then the appraiser that was appointed by such other party within such
30 day period will be the sole appraiser.  If two appraisers are properly
appointed and such first two appraisers are unable to agree on a third appraiser
within thirty (30) days after the appointment of the second appraiser, then such
third appraiser will be appointed by the presiding judge of the Los Angeles
County Superior Court, or by any person to whom such presiding judge formally
delegates the matter, or, if such methods of appointment fail, by the American
Arbitration Association.

          The parties will submit a copy of this Lease to the sole appraiser or
the three appraisers, as the case may be.  If the appraisal is conducted by a
sole appraiser, such sole appraiser will render to Landlord and Tenant his or
her determination of the Market Rent applicable during the period in question to
the parties by the 60th day after the Appraisal Request was made. If the
appraisal is conducted by three appraisers, each appraiser will submit his or
her determination(s) of the Market Rent applicable during the period in question
in a sealed envelope by the 30th day following appointment of the last
appraiser, and any determinations not submitted by such time shall be
disregarded.  In such cases, the parties will meet on such 30th day (or if it is
not a business day, on the first business day thereafter) at 11:00 a.m. at the
office of Landlord, or such other place as the parties may agree, and
simultaneously deliver the determinations.  If the determinations of at least
two of the appraisers are identical in amount, such amount will be deemed the
decision of the appraisers.  If the determination of the three appraisers are
different in amount, the decision as to the Market Rent will be independently
determined as follows:

               (a)  If neither the highest nor lowest determination differs from
          the middle determination by more than 15% of such middle
          determination, then the decision will be deemed to be the average of
          the three determinations; and



<PAGE>

               (b)  If clause (a) does not apply, then the decision will be
          deemed to be the average of the middle determination and the
          determination closest in amount to such middle determination.


          The decision of the appraisers, determined as above set forth, will be
final and non-appealable.  The fees and expenses of the appraiser or appraisers
will be shared equally by Landlord and Tenant.

          During the period of time that any appraisal is pending under this
Lease, Tenant shall pay Base Rent at the rate that was last in effect under the
Lease and the appropriate retroactive adjustment shall be made between the
parties within 10 days after the appraisers have made their determination.

To Issuer:
The Development Bank of Singapore, Ltd. (New York Agency)
[Address of Bank]
Attn:  Letter of Credit Department

Gentlemen:

          The undersigned are, collectively, the "Beneficiary" of the captioned
IRREVOCABLE STANDBY LETTER OF CREDIT (the "Standby Letter").  As the "Issuer,"
you established the Standby Letter in Beneficiary's favor for the account of the
"Customer," GREENVILLE DALLAS DELAWARE, INC.  Beneficiary hereby draws on the
Standby Letter in the amount of________________________________________________
Dollars (US$________________________).

          In support of this drawing, Beneficiary hereby certifies and warrants:

     1.   The Standby Letter was issued to back up certain of Customer's
obligations under a lease (the "Lease"), as more particularly described in the
Standby Letter.

     2.   The Customer has defaulted on one or both of the following obligations
(Beneficiary must so indicate below) imposed upon Customer by the Lease:

          (a)  Customer has failed to keep the Standby Letter in effect for the
               period of time required by paragraph 23 of the Lease [yes ____];
               or

          (b)  Customer has defaulted in the performance of Landlord's
               Environmental Indemnity in a manner and as defined in paragraph
               23 of the Lease [yes ____].

Such default(s) have not only occurred but are continuing without cure.
Beneficiary has not transferred or otherwise assigned, in whole or in part, its
rights under the Lease.



<PAGE>

     3.   This Request For Payment is attached to a Draft for the sum of
________________________________________________________________Dollars
(US$________________).  That Draft, this Request For Payment and the original
copy of the Standby Letter constitute the "Required Documents" referred to in
paragraph (4) in the Standby Letter.

     4.   If paragraph 2 (b) of this Request for Payment is applicable, under
the terms of the Lease the sum of such Draft is presently due and payable from
Customer to Beneficiary, but Customer has wrongfully failed to pay such sum.
Beneficiary served upon Customer and other parties all demands, notices, and the
like as required (if any) under the Lease.

     5.   The terms of the Lease presently entitle Beneficiary to draw upon the
Standby Letter for the full sum of the Draft to which this Request For Payment
is attached.

     6.   Each individual who has signed this Request for Payment and
accompanying Draft:

           (i)    is an officer of the Beneficiary for which such individual
                  signed, and

          (ii)    has authority to bind such Beneficiary in all matters
                  concerning the Standby Letter.

          IN WITNESS WHEREOF, the undersigned Beneficiary executed, attested
or otherwise officially sealed (as applicable), delivered, and presented this
Request (for Payment, attached to the undersigned Beneficiary's Draft, this
day of _____________________________, 19__.

          THIS AGREEMENT, dated as of ___________________________ , 199__, among
GOVERNMENT OF SINGAPORE INVESTMENT CORPORATION (REALTY) PTE. LTD., a Singapore
corporation ("Beneficiary"), GREENVILLE DALLAS DELAWARE, INC., a Delaware
corporation ("Landlord"), ADC TELECOMMUNICATIONS, INC., a Minnesota corporation,
and FIBERMUX CORPORATION, a California corporation (collectively, "Tenant").

          WITNESSETH:

          WHEREAS, Beneficiary is the beneficiary under that certain deed of
trust dated as of October 3, 1986, recorded January 26, 1988 as Instrument No.
88-109752, Official Records, Office of the County Recorder of Los Angeles, State
of California (said deed of trust, as it may be amended, increased, renewed,
modified, consolidated, replaced, combined, substituted, severed, split, spread
or extended, being hereinafter referred to as the "Deed of Trust"), between
Beneficiary and the trustor described therein (predecessor in interest to the
Landlord described above), which encumbers the land and the buildings located at
21415 and 21605 Plummer Street, Los Angeles, California, and more particularly
described therein (the "Property").

          WHEREAS, Tenant and Landlord have entered into a certain agreement
of lease dated December 18, 1992 (such Lease, as it may be hereafter amended
from time to time with the Beneficiary's consent, being referred to as the
"Lease") covering certain premises (the "Demised Premises") in the Property.

          NOW, THEREFORE, in consideration of the mutual agreements herein
contained and other good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, the parties hereto agree as follows:

     1.   Tenant covenants and agrees that the Lease now is and shall at all
times continue to be subject and subordinate in each and every respect to the
Deed of Trust. Tenant, upon request, shall execute and deliver any certificate
or other instrument which the Beneficiary may reasonably request to confirm said
subordination.

     2.   Tenant certifies that the Lease is presently in full force and effect
and unmodified and no base rent payable thereunder has been paid more than 1
(one) month in advance of its due date, and that no material default by Tenant
exists under the Lease which has continued beyond the expiration of any
applicable grace period.



<PAGE>

     3.   As long as Tenant is in compliance with the terms of this Agreement
and no default exists under the Lease which has continued beyond the expiration
of any applicable grace period, Beneficiary shall not name Tenant as a party
defendant to any action for foreclosure or other enforcement of the Deed of
Trust (unless required by law), nor shall the Lease be terminated by Beneficiary
in connection with, or by reason of, foreclosure or other proceedings for the
enforcement of the Deed of Trust, or by reason of a transfer of the landlord's
interest under the Lease pursuant to the taking of a deed or assignment in lieu
of foreclosure (or similar device), nor shall Beneficiary interfere with
Tenant's use or possession of the Demised Premises unless the holder of the
landlord's interest under the Lease (the "Landlord") would have had the right to
do so if the Deed of Trust had not been made, provided that the Person (as
defined in the Deed of Trust) acquiring, or succeeding to, the interests of the
Landlord as a result of any such action or proceeding, and such Person's
successors and assigns (any of the foregoing being hereinafter referred to as
the "Successor"), shall not be:

     (a)  subject to any credits, offsets, defenses or claims which Tenant may
          have against any prior Landlord, except as permitted by the Lease or
          by statute; or

     (b)  bound by base rent which Tenant might have paid for more than the
          current month to any prior Landlord, unless such prepayment shall have
          been made with Beneficiary's prior written consent; or

     (c)  liable for any act or omission of any prior Landlord; or

     (d)  bound by any covenant to undertake or complete any improvement to the
          Demised Premises or the building forming a part of the Property except
          as expressly required of the Landlord pursuant to the Lease; or

     (e)  required to account for any security deposit other than any security
          deposit actually delivered to the Successor; or

     (f)  liable for any payment to Tenant of any sums, or the granting to
          Tenant of any credit, in the nature of a contribution towards the cost
          of preparing, furnishing or moving into the Demised Premises or any
          portion thereof except as expressly required of the Landlord pursuant
          to the Lease.

     4.   If the interest of the Landlord under the Lease shall be transferred
by reason of foreclosure or other proceedings for enforcement of the Deed of
Trust or pursuant to a taking of a deed in lieu of foreclosure (or similar
device), Tenant shall be bound to the Successor under all of the terms,
covenants and conditions of the Lease for the balance of the term thereof
remaining, with the same force and effect as if the Successor were the Landlord,
and Tenant hereby does (a) agree to attorn to



<PAGE>


the Successor, including Beneficiary if it be the Successor, as its Landlord,
(b) affirm its obligations under the Lease, and (c) agree to make payments of
all sums due under the Lease to the Successor, said attornment, affirmation and
agreement to be effective and self-operative without the execution of any
further instruments, upon the Successor succeeding to the interest of the
Landlord under the Lease.  Tenant waives the provisions of any statute or rule
of law now or hereafter in effect that may give or purport to give it any right
or election to terminate or otherwise adversely affect the Lease or the
obligations of Tenant thereunder by reason of any foreclosure or similar
proceeding.

     5.   Tenant shall not change the terms, covenants, conditions and
agreements of the Lease in a manner which materially reduces the rent or other
charges payable or space demised thereunder or has a material adverse effect
upon the value of the landlord's interest thereunder without the express consent
in writing of the Beneficiary.

     6.   Tenant shall notify Beneficiary of any default of the Landlord under
the Lease which would entitle Tenant to cancel the Lease or abate the rent or
any additional rent payable thereunder, and agrees that Beneficiary shall have
the same rights to cure any such default as are afforded to the Landlord under
the Lease.

     7.    Anything herein or in the Lease to the contrary notwithstanding, in
the event that Beneficiary shall acquire title to the Property, Beneficiary
shall have no obligation, nor incur any liability, beyond Beneficiary's then
interest, if any, in the Property and Tenant shall look exclusively to such

                                 WILLIAM J. CADOGAN

          This Agreement made and entered into as of November 1, 1990 by and
between WILLIAM J. CADOGAN and ADC TELECOMMUNICATIONS, INC., a Minnesota
corporation, (hereinafter the "Employer").


                                    SECTION 1

                                  INTRODUCTION

1.1  BASIS OF AGREEMENT.  In consideration of the services performed by WILLIAM
J. CADOGAN for the Employer in the past and to be performed in the future, the
Employer hereby agrees to pay, in addition to other consideration to be provided
by the Employer, deferred compensation to him under the terms and conditions
hereinafter set forth.  This Agreement creates an unfunded, nonqualified plan
maintained primarily for the purpose of providing deferred compensation for a
select group of management or highly compensated employees as contemplated by
the Employee Retirement Income Security Act of 1974 ("ERISA") and shall be
construed and administered accordingly.

1.2. DEFINITIONS.  When used herein with initial capital letters, the following
words have the following meanings:

     1.2.1.    ACCRUED BENEFIT - the dollar amount determined for WILLIAM J.
CADOGAN as of the date of his Termination of Employment (and payable monthly to
him in the Single Life Annuity form, beginning on the first day of the calendar
month following his Termination of Employment or age sixty (60) years, if later)
equal to the product of (a) multiplied by (b):

     (a)  FULL SUPPLEMENT.  A dollar amount equal to:

          (i)  Fifty percent (50%) of his Average Monthly Compensation
               determined as of the date of his Termination of Employment, minus

          (ii) The sum of:  (A) his Qualified Plans Benefit determined as of one
               day before the date of his Termination of Employment, and (B)
               fifty percent (50%) of the monthly amount of his Social Security
               Benefit determined as of one day before the date of his
               Termination of Employment.

     (b)  SERVICE RATIO.  A fraction, not greater than one (1):

          (i)  The numerator of which is the total years and fractions of years
               of his service with the Employer from the Effective Date through
               and including the date of his Termination of Employment, and

          (ii) The denominator of which is eight (8).

     1.2.2.    ACTUARIAL EQUIVALENT - a benefit of equivalent value computed on
the basis of actuarial tables, factors and assumptions set forth in this
Agreement (including the Appendix A to this Agreement).




<PAGE>

     1.2.3.    AVERAGE MONTHLY COMPENSATION - one-sixtieth (1/60th) of the total
dollar amount of Compensation attributable to the sixty (60) consecutive
calendar months ending immediately before WILLIAM J. CADOGAN'S Termination of
Employment subject, however, to the following:

     (a)  LESS THAN 5 YEARS.  If he shall have received Compensation
          attributable to less than all of the sixty (60) consecutive calendar
          months ending immediately before the Termination of Employment, his
          Average Monthly Compensation shall be equal to the total of all the
          Compensation attributable to all calendar months to which any of his
          Compensation is attributable divided by the greatest number of
          consecutive calendar months to which any of his Compensation is
          attributable.

     (b)  FIVE-YEAR LIMIT.  In determining his Average Monthly Compensation,
          there shall be disregarded all Compensation attributable any calendar
          months other than the sixty (60) consecutive calendar months ending
          immediately before the Termination of Employment.

     (c)  NO COMPENSATION.  The absence of Compensation in any calendar month
          shall not affect the requirement that only sixty (60) consecutive
          calendar months ending immediately before the Termination of
          Employment be considered in determining Average Monthly Compensation.

     1.2.4.    BOARD OF DIRECTORS - the Board of Directors of the Employer or a
duly authorized committee of less than all the Directors.

     1.2.5.    CHANGE IN CONTROL - an event defined as a Change in Control in
section 7.6.2 of the ADC TELECOMMUNICATIONS, INC. PENSION PLAN (1885
Restatement), as that document and that definition may exist from time to time.

     1.2.6.    COMPENSATION - amounts paid to WILLIAM J. CADOGAN by the Employer
and all affiliates for services rendered, reported as income subject to federal
income taxes on Treasury Form W-2 for the applicable year; subject, however, to
the following:

     (a)  EXCLUDED ITEMS.  In determining his Compensation, there shall be
          (i) all discretionary bonuses not paid pursuant to a formal plan, and
          (ii) all foreign service allowances, foreign tax equalization
          payments, expense reimbursements, moving expense payments or other
          similar extra compensation, and (iii) all noncash remuneration and
          (iv) all deferred compensation (except as provided in (b) below),
          excess life insurance premiums, the value of stock options (whether or
          not exercised), and (iv) the value of restricted stock or similar
          awards and any cash payments made in connection with any such
          restricted stock award.

     (b)  ADDED ITEMS.  Remuneration which would have been paid by the Employer
          or an affiliate but which was not paid because he entered into an
          agreement to reduce earnings as a condition of participation in a plan
          established under section 125 or section 401(k) of the Internal
          Revenue Code, shall be considered to have been paid at the time when
          it would have been paid but for such agreement to reduce earnings.
          Remuneration which would have been paid by the Employer or an
          Affiliate but which was not paid because he entered into an agreement
          to defer compensation under a nonqualified plan of deferred
          compensation shall be considered to have been paid at the time it
          would have been paid but for such agreement to defer earnings.

     (c)  ATTRIBUTION TO PERIODS.  His Compensation shall be considered
          attributable to the calendar month in which it is actually paid (and
          not when earned or accrued) except that annual incentive payments
          shall be considered attributable

                                       -2-

          to the last day of the last calendar month in the fiscal period with
          respect to which they are paid.

     (d)  EXCLUDED PERIODS.  Amounts attributable to calendar months commencing
          after the earliest of the date he became Disabled or had a Termination
          of Employment shall not be taken into account in determining his
          Compensation.

     (e)  FINAL PAYMENTS.  Final payments on account of Termination of
          Employment (I.E., severance payments) and settlement for accrued but
          unused vacation and sick leave shall not be taken into account in
          determining his Compensation.

     1.2.7.    DISABILITY, DISABLED - a medically determinable physical or
mental impairment which constitutes disability under the Employer's separate
long term disability plan.

     1.2.9.    EMPLOYER - ADC TELECOMMUNICATIONS, INC., a Minnesota corporation,
and any successor thereof that adopts this Agreement.

     1.2.10.   QUALIFIED PLANS BENEFIT - a dollar amount determined for WILLIAM
J. CADOGAN as of the last day of the calendar month in which his Termination of
Employment occurs or, if later, the last day of the calendar month in which he
would attain age sixty (60) years (and expressed in terms of a monthly annuity
payable to him in the Single Life Annuity form beginning on the first day of the
calendar month following his Termination of Employment or, if later, the first
day of the calendar month following the date he would attain age sixty years)
which is the sum of the:

     (a)  accrued benefit developed for him as of the date of his Termination of
          Employment under all qualified defined benefit pension plans
          maintained by the Employer when expressed in the form of a Single Life
          Annuity first payable on the first day of the first calendar month
          following his Termination of Employment or, if later, the first day of
          the calendar month following the date he would attain age sixty (60)
          years; and

     (b)  the Actuarial Equivalent monthly amount of annuity payable to him when

          benefits are attributable to contributions of the Employer (and

          indirectly made by him) under all qualified defined contribution

     1.2.11.   SINGLE LIFE ANNUITY - a form of annuity that is payable monthly
to and for the lifetime of WILLIAM J. CADOGAN, the first such payment to be due

first day of the calendar month in which his death occurs.

     1.2.12.   SOCIAL SECURITY BENEFIT - the monthly amount available for the
benefit of WILLIAM J. CADOGAN at:

     (a)  at age sixty-two (62) years if his Termination of Employment is before
          age sixty-two (62) years (calculated on the assumption that he will
          have no additional earnings from his Termination of Employment until
          age sixty-two (62) years); or

     (b)  the date of his Termination of Employment if his Termination of
          Employment is after age sixty-two (62) years but before age sixty-five
          (65) years; or

     (c)  age sixty-five (65) years, if his Termination of Employment is at or
          after age sixty-five (65) years;

(excluding amounts available for spouse and dependents) as an old age benefit
under the provisions of Title II of the federal Social Security Act in effect on
the date of the Termination of Employment (or age sixty-five, if earlier),
whether or not payment of such amount is delayed, suspended or forfeited because
of failure to apply, acceptance of other work, or any other similar reason
within his control. For this purpose, unless he shall have furnished verified
proof of wages before his Termination of Employment, he shall be deemed to have
had taxable wages at or above the taxable wage base in all years prior to the
year of his Termination of Employment.

     1.2.13.   SUPPLEMENTAL RETIREMENT BENEFIT - the benefit payable under this
Plan upon the Termination of Employment of WILLIAM J. CADOGAN, subject to the
conditions and limitations set forth in this Plan Statement.

     1.2.14.   TERMINATION OF EMPLOYMENT - a complete severance of WILLIAM J.
CADOGAN'S employment relationship with the Employer and its subsidiaries or
affiliates, if any, for any reason other than his death.  A transfer from
employment with the Employer to employment with an affiliate of the Employer
shall not constitute a Termination of Employment.

1.3. RULES OF INTERPRETATION.  An individual shall be considered to have
attained a given age on his birthday for that age (and not on the day before).
The birthday of any individual born on a February 29 shall be deemed to be
February 28 in any year that is not a leap year.  Notwithstanding any other
provision of this Agreement or any election or designation made under this
Agreement, any individual who feloniously and intentionally kills WILLIAM J.
CADOGAN or any surviving spouse shall be deemed for all purposes of this
Agreement and all elections and designations made under this Agreement to have
died before him or his surviving spouse.  A final judgment of conviction of
felonious and intentional killing is conclusive for the purposes of this
Section.  In the absence of a conviction of felonious and intentional killing,
the Board of Directors shall determine whether the killing was felonious and
intentional for the purposes of this Section.  Whenever appropriate, words used
herein in the singular may be read in the plural, or words used herein in the
plural may be read in the singular; the masculine may include the feminine; and
the words "hereof," "herein" or "hereunder" or other similar compounds of the
word "here" shall mean and refer to the entire Agreement and not to any
particular paragraph or section of this Agreement unless the context clearly
indicates to the contrary.  The titles given to the various sections of this
Agreement are inserted for convenience of reference only and are not part of
this Agreement, and they shall not be considered in determining the purpose,
meaning or intent of any provision hereof.  Any reference in this Agreement to a
statute or regulation shall be considered also to mean and refer to any
subsequent amendment or replacement of that statute or regulation.  This
instrument has been executed and delivered in the State of Minnesota and has
been drawn in

                                       -4-

conformity to the laws of that State and shall, except to the extent that
federal law is controlling, be construed and enforced in accordance with the
laws of the State of Minnesota.


                                    SECTION 2

                     SUPPLEMENTAL RETIREMENT INCOME BENEFIT

2.1. SUPPLEMENTAL RETIREMENT BENEFIT.

     2.1.1.    WHEN AVAILABLE.  Upon the Termination of Employment of
               WILLIAM J. CADOGAN:

     (a)  at or after his attainment of age fifty (50) years; or

     (b)  at the written request of the Board of Directors; or

     (c)  within six (6) months after a Change in Control; or

     (d)  after, and on account of, his Disability.

and upon the filing of a written application with the Board of Directors, he
shall receive a Supplemental Retirement Benefit.

     2.1.2.    AMOUNT.  The amount of WILLIAM J. CADOGAN'S Supplemental
Retirement Benefit shall be the Actuarial Equivalent single lump sum of his
Accrued Benefit determined as of his Termination of Employment reduced, however,
five-twelfths of one percent (5/12%) for each month by which the payment of the
Supplemental Retirement Benefit precedes the last day of the calendar month in
which he attains age sixty (60) years.

     2.1.3.    FORM OF PENSION.  For the purpose of defining the amount of the
Supplemental Retirement Benefit in Section 2.1.2, the benefit is derived from a
Single Life Annuity, the first payment of which is due on the first day of the
calendar month which follows his Termination of Employment or, if later, the
first day of the calendar month which follows the date he would attain age sixty
(60) years.  Notwithstanding the foregoing, this annuity shall be, in all cases,
converted to and paid in the form of an Actuarial Equivalent single lump sum
benefit on the first day of the calendar month following his Termination of
Employment. Such payment shall be in full and complete discharge of all benefits
payable to, or with respect to him under this Agreement including, but not
limited to, all survivor benefits and all optional forms of benefit to which he
or his spouse might otherwise have been entitled.  The consent of a spouse,
joint annuitant or beneficiary shall not be required before making the single
lump sum payment herein described.

2.2. NO OTHER BENEFITS.  No benefits are available under this Plan upon the
Termination of Employment of WILLIAM J. CADOGAN before he is entitled to the
Supplemental Retirement Benefit specifically enumerated herein.

2.3. FACILITY OF PAYMENT.  In case of the legal disability, including minority,
of WILLIAM J. CADOGAN, joint annuitant or beneficiary entitled to receive any
distribution under the Agreement, payment shall be made, if the Board of
Directors shall be advised of the existence of such condition:

     (a)  to his or her duly appointed guardian, conservator or other legal
          representative, or

     (b)  to a person or institution entrusted with the care or maintenance of
          the incompetent or disabled person, provided such person or
          institution has satisfied the Board of Directors that the payment will
          be used for the best

                                       -5-


<PAGE>

          interest and assist in the care of such person, and provided further,
          that no prior claim for said payment has been made by a duly appointed
          guardian, conservator or other legal representative of such person.

Any payment made in accordance with the foregoing provisions of this section
shall constitute a complete discharge of any liability or obligation of the
Employer and the Board of Directors.

2.4. FORFEITURE OF BENEFITS.  All unpaid benefits under this Plan payable to or
with respect to WILLIAM J. CADOGAN, including without limiting the generality of
the foregoing, undistributed commuted values, shall be immediately and
permanently forfeited upon the determination by the Board of Directors that he,
either before or after Termination of Employment:

              (i)   engaged in a felonious or fraudulent conduct resulting in
                    material harm to the Employer or an affiliate; or

             (ii)   made an unauthorized disclosure to a competitor of any
                    material confidential information, trade information, or
                    trade secrets of the Employer or an affiliate; or

            (iii)   provided the Employer or an affiliate with materially false
                    reports concerning his business interests or employment; or

            (iv)    made materially false representations which are relied upon
                    by the Employer or an affiliate in furnishing information to
                    shareholders, accountants, a stock exchange, the Securities
                    and Exchange Commission or public or private regulatory
                    body; or

             (v)    maintained an undisclosed, unauthorized and material
                    conflict of interest in the discharge of the duties owed by
                    him to the Employer or an affiliate; or

            (vi)    engaged in conduct causing a serious violation of state or
                    federal law by the Employer or an affiliate; or

           (vii)    engaged in the theft of assets or funds of the Employer or
                    an affiliate; or

          (viii)    has been convicted of any crime which directly or indirectly
                    arose out of his employment relationship with the Employer
                    or an affiliate or materially affected his ability to
                    discharge the duties of his employment with the Employer or
                    an affiliate; or

            (ix)    engaged during his employment in any employment or
                    self-employment with a competitor of the Employer or an
                    affiliate; or

             (x)    engaged during a period of two (2) years after his voluntary
                    termination of employment with the Employer in any
                    employment or self-employment with a competitor of the
                    Employer or an affiliate within the geographical area which
                    is then served by the Employer or the affiliate.

He shall be notified within thirty (30) days of any such decision by the Board
of Directors.  He may contest such action by filing a claim as prescribed in
Section 6.4.

     3.1.2.    AMOUNT.  The amount of the lump sum survivor benefit shall be:

     (a)  If he had not Terminated Employment at the date of his death, the

          which he would have received if he had Terminated Employment on the
          date of his death at the written request of the Board of Directors
          (and not by reason of his death).

     (b)  If he had Terminated Employment at the date of his death and had not
          received the payment to which he was entitled under Section 2.1, the

Agreement.  The rights of WILLIAM J. CADOGAN under this Agreement (or of any
surviving spouse with respect to him) shall be solely those of an unsecured
general creditor of the Employer.  If, for its own internal purposes, the
Employer elects to purchase life insurance policies on his life or any other

beneficiary of such policies or assets (all such rights being retained by the
Employer) and shall not have any preferred claim or interest in any such
policies, assets or the proceeds thereof.  The Employer makes no representation
that it will actually use any life insurance policies, other assets or proceeds

this Agreement.

Employer or the Board of Directors recognize any assignment thereof, either in
whole or in part, nor shall it be subject to attachment, garnishment, execution
following judgment or other legal process.

                            AMENDMENT AND TERMINATION

                      DETERMINATION OF ACTUARIAL EQUIVALENT
                             TO SINGLE LIFE ANNUITY


     Section 1.  LUMP SUM SETTLEMENTS.  When converting benefits to a single
lump sum for payment to WILLIAM J. CADOGAN, the benefit to be converted is the
Single Life Annuity form payable at the latest date such benefit may commence.
When converting benefits to a single lump sum for payment to any other person,
the benefit to be converted shall be the benefit payable to such other person at
the latest date such benefit may commence.  The factors to be used to convert
the Single Life Annuity form to a lump sum benefit shall be:

INTEREST ASSUMPTION:  One hundred twenty percent (120%) of the interest rate
used by the Pension Benefit Guaranty Corporation to value immediate annuities in
the event of plan terminations occurring on the first day of the calendar year
in which occurs the date as of which the Actuarial Equivalent amount of benefit
is being determined

MORTALITY ASSUMPTION:  The 1983 Group Annuity Mortality Table (male lives) or a
later table adopted by the State of Minnesota Insurance Department as a reserve
basis for group annuities issued by life insurance companies doing business in
Minnesota


     Section 2.  DEFINED CONTRIBUTION PLAN ACCRUAL.  To determine the Actuarial
Equivalent annuity value of WILLIAM J. CADOGAN'S account balances attributable
to contributions of the Employer in defined contribution plans as of a specified
date (expressed in the Single Life Annuity form beginning on the first day of
the calendar month following his Normal Retirement Age) the following steps
shall be followed:

     (a)  Determine the value of all such defined contribution plan accounts as
of the valuation date under each defined contribution plan which is coincident
with or immediately preceding such specified date;

     (b)  Increase such account balances from such valuation dates to the last
day of the calendar month in which his Termination of Employment occurs or, if
later, the last day of the calendar month in which he would attain age sixty
(60) years at an assumed rate of earnings equal to eight percent (8%),
compounded annually;

     (c)  Convert the resulting total to an Actuarial Equivalent amount of
monthly annuity in the Single Life Annuity form commencing on the last day of
the calendar month in which his Termination of Employment occurs or, if later,
the last day of the calendar month in which he would attain age sixty (60) years
by applying the interest and mortality factors set forth in Section 1 above.

     Section 3.  GENERAL FACTORS.  Except to the extent otherwise specified in
the Agreement, the following interest and mortality factors shall be used in
determining the Actuarial Equivalent amount of any benefit:

INTEREST ASSUMPTION:  One hundred twenty percent (120%) of the interest rate
used by the Pension Benefit Guaranty Corporation to value immediate annuities in
the event of plan terminations occurring on the first day of the calendar year
in which occurs the date as of which the Actuarial Equivalent amount of benefit
is being determined

MORTALITY ASSUMPTION:  The 1983 Group Annuity Mortality Table (male lives) or a
later table adopted by the State of Minnesota Insurance Department as a reserve
basis for group annuities issued by life insurance companies doing business in
Minnesota
