ITEM 1. BUSINESS
 
GENERAL
 
     Plantronics, Inc. (the "Company" or "Registrant") is a leading designer,
manufacturer and marketer of lightweight communication headsets and headset
accessories and services. In addition, the Company manufactures and markets
specialty telephone products, such as amplified telephone handsets and specialty
telephones for hearing-impaired users, and noise-canceling handsets for use in
high-noise environments.
 
     The Company's headsets, which can be worn over the head or on either ear,
are recognized in the industry for their safety, quality and reliability. The
Company has well-developed distribution channels in North America and Europe,
where growth of telemarketing activities and deregulation of the telephone
companies have led to more widespread use of telephone headsets. The Company's
headsets are also becoming more widely used in the Middle East, Africa,
Australia, the Far East and Latin America.
 
     The Company's headset products are used worldwide by call center users,
such as telemarketing personnel, reservation agents, telephone operators and air
traffic controllers, whose occupations involve the constant use of a telephone
or communications console. In North America and Europe, the number of call
center users has grown significantly over the last 10 years. The use of headsets
by call center users has become an industry standard. While the Company believes
that the number of call center users in these geographic markets will continue
to grow, it expects that the primary source of future sales growth in such
markets will result from repeat sales to existing customers, including the
replacement of products presently in use with new and improved products.
 
     The Company believes that the demand for headsets in the rest of the world
offers more significant growth opportunities for the Company. To date, the
Company's most significant penetration of foreign market segments has been the
call center user market segment in Europe. The potential for growth in the
foreign market segments is the result of such developments as the rapid
expansion of the telecommunications infrastructure and increasing worldwide use
of telemarketing techniques.
 
     The Company also sells headsets in the business and home office user market
segment, which the Company has identified as an area of long-term growth
potential. Users in this market segment consist of business executives, agents,
brokers, lawyers, accountants, home office business people and other
professionals whose occupations may require intensive (but not constant) use of
a telephone. The business and home office user market segment can be divided
into users who attach their headsets to telephones, cellular telephones or to
computers. The use of headsets for mobile communications and as computer
peripherals is a significant growth area for headset sales. Potential
applications in this market segment include mobile communications, personal
computer conferencing, computer telephony integration ("CTI"), voice recognition
and multimedia applications.
 
     The Company sells its headsets to a broad and diverse group of end-user
customers worldwide, including regional telephone operating companies, operators
of private telephone networks, and governmental agencies. The Company
distributes its products through large electronics wholesalers, specialized
headset distributors, directly to original equipment manufacturers ("OEMs"), and
through retail channels, such as office supply and consumer electronics stores,
mail order catalogs, warehouse clubs and office supply distributors.
 
PRODUCTS
 
     The Company's product line consists of communication headsets, headset
accessories and services, and specialty telephone products. None of the
Company's products or business is considered seasonal.
<PAGE>   4
 
     HEADSETS
 
     Communication headsets allow users who must perform other tasks while using
a telephone to work more effectively, efficiently and comfortably than with a
telephone handset, while providing greater communications clarity and security
than a speaker phone.
 
     Headsets consist of two distinct units. The "top," which is the portion
that the user wears and which is comprised of the receiver capsule and voice
tube, and the "bottom," or adapter which interfaces with the telephone or other
equipment. Both units are currently required in most applications. In some
circumstances, however, the interface is built into the telephone, computer or
other equipment with which the headset is being used, allowing use of the "top"
alone.
 
     There are four basic headset "top" styles:
 
     - Headsets that rest in the outer portion of the ear. The FreeHand headset,
     introduced during fiscal year 1995, offers a functional and lightweight
     design that allows it to be easily and quickly placed on or removed from
     its position in the outer portion of the ear with one hand. Its adjustable
     microphone boom may be rotated for optimum transmit performance. The CAT-72
     miniature headset, introduced during fiscal year 1994 for use with personal
     computers, is lightweight, unobtrusive and different in appearance from
     other models with its small solid shape containing both a receiver and a
     microphone without a separate voice tube. It is the Company's smallest
     headset, weighing less than 6 grams and measuring only 2-1/2 inches in
     length.
 
     - Over-the-head headsets with ear cushions. The Supra headset is an
     over-the-head model available with sound reception in one or both ears, and
     the unit's dual ear cushions help block out background noise. The Company
     introduced a new product in this category in fiscal year 1996, the Encore
     headset, with a design developed from data in the Company's human factors
     database. The Encore headset features all of the qualities of the Supra
     headset, plus user-controllable tone adjustment.
 
     - Behind-the-ear headsets with an ear tip. The StarSet headset is the
     distinctive Plantronics headset that uses a small capsule that fits behind
     and in the outer portion of the ear. Sound is delivered to the ear by an
     acoustic ear tip. The headset is extremely lightweight, requiring no
     headband, and the ear tip's acoustic coupling provides exceptional sound
     quality. The TriStar headset, the industry's lightest commercial headset,
     was introduced during fiscal year 1996. This product features maximum user
     adjustments for excellent stability, comfort and sound quality.
 
     - Behind-the-ear headsets with a receiver that rests on either ear. The
     Mirage headset uses a miniaturized behind-the-ear capsule. Attached to it
     is a small disc-shaped receiver that rotates to fit against either ear. The
     receiver rests gently on the ear, not in it.
 
     All basic telephone-based headset tops are designed for use with the
multitude of different phone systems currently available. Basic models offer
features such as user volume control, a mute switch and quick-disconnect, which
allows users to leave the phone without removing their headsets or disconnecting
the line. Supra NC, StarSet NC, Mirage NC, TriStar NC and Encore NC headset tops
are special versions of the Supra, StarSet, Mirage, TriStar and Encore headsets
featuring boom-mounted noise-canceling microphones instead of voice tubes.
 
     The Company's Vista headset bottoms feature a universal modular adapter and
interchangeable headset tops. The universal adapter eliminates compatibility
problems with almost all telephones and incorporates the SoundGuard Plus system,
which provides volume control for improved audio comfort and clarity. The
interchangeability feature of the Vista product allows a user to connect any one
of the available Plantronics headset tops to any telephone or console equipped
with the Vista adapter or the Company's Starbase headset telephone.
 
     In fiscal year 1997, the Company introduced a new bottom or adapter called
the Headset Switcher adapter for use with a telephone and a computer equipped
with a soundcard. The Headset Switcher allows the user to switch back and forth
from the telephone and computer audio applications by simply flipping a switch.
 
                                        2
<PAGE>   5
 
     In addition to its traditional corded products, the Company introduced
during fiscal year 1996 the CT-460, a cordless headset telephone aimed at the
home office market segment. This product is comprised of a headset and remote
transceiver/dial pack, and a base unit which plugs into a wall jack. The product
is sold principally through retail channels. In fiscal year 1997 the Company
introduced the CHS132 and CLA132 products specifically designed for the mobile
telephone market segment. The CHS132 is a lightweight corded headset which is
designed to be used with some of the largest mobile telephone manufacturers'
products which incorporate a telephone headset port. The CLA132 is a CHS132
product with a cigarette lighter adapter which allows a headset to be used with
mobile telephones which do not have a telephone headset port.
 
     HEADSET ACCESSORIES AND SERVICES
 
     The Company offers a complete line of headset accessories, including voice
tubes, ear cushions, ear tips and background noise suppressors. The Company's
Service Center provides customers with a sophisticated service and refurbishment
program including headset repair and remanufacturing.
 
     SPECIALTY TELEPHONE PRODUCTS
 
     The Company's Walker Equipment Division (the "Walker Division") is a
designer and distributor of specialty telephone products. Specialty telephone
products sold under the Walker Division name include amplified handsets,
amplified telephones and telephone amplifier accessories for the
hearing-impaired user. The Walker Division Clarity telephone is a full-featured
single-line telephone designed for hearing-impaired users and was redesigned in
fiscal year 1996. It features volume control circuitry, oversized buttons, a
ringer volume control and a light that flashes when the phone rings. In
addition, the Walker Division sells special noise-canceling handsets for
high-noise environments, as well as for entry and elevator phones. The Walker
Division also offers a device that will amplify the receive volume of
conventional handsets and recently introduced a portable version of that
product. The Walker Division products are currently distributed through the same
commercial and retail distribution channels as the Company's products.
 
     In fiscal year 1997, the Walker Division introduced a new product for home
use, the Personal Paging System. This is a personal notification system that
alerts people to important sounds, such as the telephone, doorbell or crying
baby, when the remote unit vibrates to alert the individual.
 
     In Europe, where modular telephone handsets are not currently the norm, the
Company developed the Starbase headset telephone, which is a full-featured
single-line telephone to which nearly all of the Company's headsets may be
attached. This product enables many more businesses to use headsets for
non-operator functions.
 
     In addition, the specialty telephone products operation provides headsets
for special applications that are not served by the Company's standard product
lines.
 
PRODUCT DEVELOPMENT
 
     Since the introduction of the original lightweight headset in 1962, the
user has been the primary focus of the Company's design efforts. The Company's
concern for "human engineering" and its efforts to "design-in" comfort and
safety have resulted in such product innovations as a behind-the-ear capsule
(containing both microphone and receiver) designed to fit all users comfortably
and the SoundGuard Plus system, which provides volume control and improved audio
comfort and quality.
 
     The Company has a number of product development programs currently
underway, including a new generation of headset systems, computer and mobile
products, a wireless product family and several core technology programs. The
Company supplements its in-house engineering capabilities through selected
outside contracting arrangements.
 
     Research, development and engineering expenditures were $11.6 million,
$13.7 million, and $14.5 million for the fiscal years ended April 1, 1995, March
30, 1996, and March 29, 1997, respectively. The Company's management believes
that substantial investment in research and development is important for the
Company
 
                                        3
<PAGE>   6
 
to maintain its position in the industry and, therefore, intends to increase its
spending for research, development and engineering in subsequent fiscal years.
 
     Historically, substantially all of the Company's product development
efforts have primarily been directed toward incremental enhancements of existing
products. In the future, the Company intends both to enhance its existing
products and to develop new products that capitalize on its core technology and
expand the Company's product offerings to new user market segments. The success
of new product introductions is dependent on several factors, including proper
new product selection, timely completion and introduction of new product
designs, quality of new products and market acceptance. Although the Company has
attempted to determine the specific needs of the telephone, mobile telephone and
computer segments of the business and home office user segments of the market,
there can be no assurance that the market niches identified will in fact
materialize or that the Company's existing and future products designed for
these market segments will gain substantial market acceptance.
 
     The technology of telephone headsets, both "tops" and "bottoms," has
traditionally evolved slowly. Products are currently exhibiting life cycles of
three to five years before introduction of the next generation of products,
which usually include stylistic changes and quality improvements but are based
on similar technology. The Company believes that future changes in technology
may come at a faster pace, particularly in the telephone, cellular telephone and
computer segments of the business and home office user parts of the market. The
Company's future success will be dependent in part on its ability to develop
products that utilize new technologies and to introduce them to the marketplace
successfully. In addition, in order to avoid product obsolescence, the Company
will have to monitor technological changes in telephony, as well as users'
demands for new technologies. Failure by the Company to keep pace with future
technological changes could materially adversely affect the Company's revenues
and operating results.
 
SALES AND DISTRIBUTION
 
     The Company distributes its products worldwide through large electronics
wholesalers, specialized headset distributors, OEMs, and retail channels.
 
     Electronics wholesalers, which are often national organizations offering
hundreds of products, including headsets, to both resellers and end users,
represent the single largest channel of distribution for the Company's products.
The Company's products are currently sold in North America through electronics
distributors, including Graybar Electric Company, Anixter Brothers and Sprint
North Supply. Additional distributors handle the Company's products in overseas
market segments.
 
     Specialized headset distributors represent a second major distribution
channel for the Company's products. These distributors, which sell on a national
basis, are generally smaller companies with total annual revenues of under $10
million, the majority of which are generated by their sales of headsets.
 
     OEMs supply automatic call distributor systems and other telecommunications
and computer equipment that utilize headsets. Depending on their marketing
strategies, OEMs may purchase the Company's headsets on a private label basis.
The Company believes that it is currently the predominant supplier of headsets
to Lucent Technologies (formerly part of AT&T). For the computer segment of the
business and home office user part of the market, the Company supplies products
to Intel Corporation and other OEMs for use in their personal computer systems.
 
     Retail channels, including office supply and consumer electronics
retailers, warehouse clubs, consumer products and office supply distributors,
and catalog and mail order companies. These retailers sell headsets to many
small businesses, small offices and home offices.
 
     Direct sales are made in a limited number of cases by the Company to
government agencies, including NASA, the FAA, and under the Company's General
Service Administration schedule contract. Direct sales tend to be more customary
in Europe than in North America.
 
     Financial Information about Industry Segments and Foreign Operations. The
Company operates in one industry segment. Financial information about foreign
and domestic operations and export sales, included in
 
                                        4
<PAGE>   7
 
Note 9 to the Company's Consolidated Financial Statements, appearing at page 13
of the Company's 1997 Annual Report to Stockholders is incorporated herein by
this reference.
 
     Approximately 30.5%, 26.8%, and 24.5% of the Company's net sales in fiscal
1997, fiscal 1996 and fiscal 1995, respectively, were derived from sales to
foreign customers. Sales to foreign customers are generally subject to such
risks as increased tariffs and the imposition of other trade barriers. Although
the Company generally transacts business internationally in United States
currency, declines in the values of local currencies relative to the United
States dollar in countries in which the Company does business could adversely
affect the Company by resulting in less competitive pricing for the Company's
products. The Company does not currently engage in any hedging activities to
mitigate exchange rate risks and to date has not been adversely affected by
fluctuating currencies. To the extent that the Company is successful in
increasing its sales to foreign customers, or to the extent that the Company
increases its transactions in foreign currencies, the Company's results of
operations could be adversely affected by exchange rate fluctuations.
 
     In fiscal 1996, the Company established a new wholly-owned subsidiary in
the Netherlands. The new subsidiary serves as a strategic logistics center as
well as the headquarters for international administration.
 
BACKLOG
 
     The Company's backlog of unfilled orders was $17.0 million on March 29,
1997, compared to $11.8 million on March 30, 1996. The Company includes in
backlog all purchase orders scheduled for delivery over the next 12 months. As
part of its commitment to customer service, however, the Company generally ships
products within two to four weeks from receipt of an order. The Company's
backlog is generally subject to cancellation or rescheduling by the customer on
short notice with little or no penalty. While the Company has not experienced
any significant cancellations in the past, the Company's backlog as of any
particular date may not be indicative of actual sales for any future period and
therefore should not be used as a measure of future revenue.
 
COMPETITION
 
     The Company believes the principal competitive factors in its business are
product reliability, product features, customer service and support, reputation,
distribution, ability to meet delivery schedules, warranty terms, product life
and price. The Company believes that its brand name recognition, distribution
network, large user base and large number of product variations, together with
its extensive experience in designing safe and reliable products, dealing with
regulatory agencies and servicing and repairing headsets, are the key factors
for the Company to maintain its position as a leading supplier of lightweight
communication headsets.
 
     In the call center user segment of the market, the Company faces different
competitors depending on the channel of distribution and the geographic
location. The Company anticipates that it may face additional indirect
competition in this market segment from technological advances such as
interactive voice response systems which require no human interface for certain
applications, such as account balance inquiries or airplane arrival and
departure schedules. The Company believes that this trend will be more than
offset by the expansion of telemarketing and catalog sales.
 
     In the business and home office user segment of the market, the same
competitors who are the Company's competitors in the call center user market
currently sell headsets to users within the telephone, cellular telephone and
computer segments of the business and home office user part of the market,
primarily through commercial distribution channels. As the Company develops new
generations of products and enters new market segments, including the developing
business and home office user segment of the market, the Company anticipates
that it may face additional competition from companies which currently do not
offer communication headsets. Such companies may be larger, offer broader
product lines and have substantially greater financial and other resources than
the Company. Such competition could negatively affect pricing and gross margins.
Although the Company has historically competed very successfully in the call
center user segment of the market, there can be no assurance that it will be
able to continue its leadership position in that segment of the market or that
the Company will be able to compete successfully in new market segments.

MANUFACTURING
 
     Production of the Company's headsets and other products consists of light
manufacturing and assembly operations conducted in California, Georgia, Mexico
(the predominant manufacturing site) and the United Kingdom. A few of the
Company's other products are manufactured in whole or in part on a contract
basis by third parties.
 
     The Company purchases the components for its headset products, including
proprietary semi-custom integrated circuits, amplifier boards and other
electrical components, from suppliers in the United States, Mexico, Asia and
Europe. Although most components and subassemblies used in the Company's
manufacturing operations are obtained, or are reasonably available, from
numerous sources, certain of its products and components are currently procured
only from single suppliers in order to obtain volume pricing. In the past, the
Company has experienced only minor interruptions in the supply of these
components, none of which has adversely affected its operations. However, an
interruption in supply from any of the Company's single source suppliers in the
future could temporarily result in the Company's inability to deliver products
on a timely basis, which in turn could adversely affect its operations. In
addition, manufacturing and assembly of the Company's products could be
adversely affected by political or economic conditions in the United States or
abroad.
 
     In order to meet the requirements of its customers for timely delivery of
products, the Company manufactures finished goods to meet forecasted customer
requirements. Since such manufacturing occurs prior to the receipt of purchase
orders, the Company maintains an inventory of finished goods in addition to raw
materials, work in process and subassemblies. Inventories were valued at $20.0
million as of March 29, 1997.
 
     In fiscal 1996, the Company began the implementation of a new worldwide
management information system and is training its personnel to operate such
system to improve service to its customers, to control its assets and to enhance
management information. Any difficulty in the operation of such new systems or
the training of personnel, or any disruptions in the transition to such new
systems, could adversely affect the Company's ability to accurately forecast
sales demand and calibrate manufacturing to such demand, to calibrate purchasing
levels, to accurately record and control inventory levels, and to record and
report financial and management information on a timely and accurate basis. The
occurrence of any of these events in the future could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
ENVIRONMENTAL MATTERS
 
     The Company is subject to various federal, state, local and foreign
environmental laws and regulations, including those governing the use, discharge
and disposal of hazardous substances in the ordinary course of its manufacturing
process. Although management believes that its current manufacturing operations
comply in all material respects with applicable environmental laws and
regulations, environmental legislation has been enacted and in the future may be
enacted or interpreted to create environmental liability with respect to the
Company's facilities or operations. The Company has included in its financial
statements a reserve of $1.0 million for possible environmental remediation
related to one of its discontinued businesses. While no claims have been
asserted against the Company in connection with this matter, there can be no
assurance that such claims will not be asserted in the future or that any
resulting liability will not exceed the amount of the reserve.
 
PATENTS AND TRADEMARKS
 
     The Company maintains a program of seeking patent protection for its
technology. Significant product features for which the Company has, or is
currently seeking, patent protection include the Company's StarSet II capsule
design, SoundGuard receiver gain compression integrated circuit, Mirage headset,
Clarity frequency enhancing telephone, battery-powered in-line amplifier with an
automatic by-pass feature to provide continuous receive signal when battery
power gets low, integrated circuit implementation for an audio amplifier
operating at extremely low power with an expander function for noise reduction
in telephony applications, headset receiver mechanical-acoustical tone control
devices, earbud receiver positioning mecha-
 
                                        6

nisms, voice tube assemblies and various other products, features including
certain wireless technology and electronic components. The existing patents
expire from 2000 to 2013.
 
     The Company's success will depend in part on its ability to obtain patents
and preserve other intellectual property rights covering the design and
operation of its products. The Company intends to continue to seek patents on
its inventions when appropriate. The process of seeking patent protection can be
lengthy and expensive, and there can be no assurance that patents will issue
from currently pending or future applications or that the Company's existing
patents or any new patents issued will be of sufficient scope or strength or
provide meaningful protection or any commercial advantage to the Company. The
Company may be subjected to, or may initiate, litigation or patent office
interference proceedings, which may require significant financial and management
resources. The failure to obtain necessary licenses or other rights or the
advent of litigation arising out of any such claims could have a material
adverse effect on the Company's operations.
 
     The Company owns registered trademarks with respect to many of its
products, including its StarSet, Supra and Mirage products and currently has
several trademark applications pending in connection with new products. The
Company also attempts to protect its trade secrets and other proprietary
information through comprehensive security measures, including agreements with
customers and suppliers, and proprietary information agreements with employees
and consultants.
 
EMPLOYEES
 
     On March 29, 1997, there were 1,515 persons employed by the Company. No
employees are currently covered by collective bargaining agreements or are
members of any labor organization as far as the Company is aware. The Company
has not experienced any work stoppages and believes that its employee relations
are good.

                 The applicable Performance Level as of any day shall be
         determined by reference to the Net Funded Debt to EBITDA Ratio as of
         the last day of the fiscal quarter most recently ended on or prior to
         such day, and any change in the Performance Level shall become
         effective upon the delivery to the Bank of the Compliance Certificate
         required to accompany the financial statements delivered pursuant to
         Section 7.01 upon which such change is based, which Compliance
         Certificate shall set forth in reasonable detail the calculation of
         the Net Funded Debt to EBITDA Ratio.

                 Each change in the Applicable Rate shall apply during the
         period commencing on the effective date of such change and ending on
         the date immediately preceding the effective date of the next such
         change.  Notwithstanding the foregoing, at any time prior to the time
         the first delivery of financial statements under Section 7.01 after
         the Closing Date, the Applicable Rate shall be determined as if the
         Net Funded Debt to EBITDA Ratio were at Performance Level 1.

         as constituted at the beginning of any relevant period or by a
         Permitted Holder or (ii) any director of the Company that has been

         director, together with any directors referred to in the preceding
         clause (i) or previously approved in accordance with this clause (ii),
         or by a Permitted Holder.

         transfer, lease or other disposition to any Person other than the

         of related transactions, of (i) any Capital Stock of any Subsidiary of

                                       9
<PAGE>   16
       the need to calculate the Consolidated Fixed Charge Coverage Ratio (such

       occurred on the first day of the Reference Period, but excluding
       Indebtedness incurred or repaid under any revolving credit or similar
       facility pursuant to which amounts incurred may be repaid and reborrowed
       for working capital purposes (it being understood that such incurrences

       actual basis), unless a permanent reduction in the commitments is
       effected by such repayment and (b) any Asset Sales or Acquisitions
       (including, without limitation, any Acquisition giving rise to the need
       to make such calculation as a result of such person or one of its
       Subsidiaries (including any person who becomes a Subsidiary as a result
       of the Acquisition) incurring, assuming or otherwise being liable for
       Acquired Indebtedness) occurring during the Reference Period, as if such
       Asset Sale or Acquisition occurred on the first day of the Reference
       Period.  Without limiting the generality of the foregoing, in making any
       calculation of the Consolidated Fixed Charge Coverage Ratio for any
       period commencing prior to January 26, 1994, the recapitalization which
       took effect on such date shall be deemed to have occurred on the first
       day of the Reference Period.  Furthermore, in calculating "Consolidated
       Interest Expense" and "Consolidated Fixed Charges" for purposes of
       determining the denominator (but not the numerator) of this
       "Consolidated Fixed Charge Coverage Ratio," (i) interest on outstanding
       Indebtedness determined on a fluctuating basis as of the Transaction
       Date and which will continue to be so determined thereafter shall be
       deemed to have accrued at a fixed rate per annum equal to the rate of
       interest on such Indebtedness in effect on the Transaction Date; (ii) if
       interest on any Indebtedness actually incurred on the Transaction Date
       may optionally be





                                       10
<PAGE>   17
       determined at an interest rate based upon a factor of a prime or similar
       rate, a eurocurrency interbank offered rate, or other rates, then the
       interest rate in effect on the Transaction Date will be deemed to have
       been in effect during the Reference Period; and (iii) notwithstanding
       clause (i) and (ii) above, interest on Indebtedness determined on a
       fluctuating basis, to the extent such interest is covered by agreements
       relating to Interest Rate Protection Obligations, shall be deemed to
       have accrued at the rate per annum resulting after giving effect to such
       agreements.  If such Person or any of its Subsidiaries directly or
       indirectly enters into a Guaranty Obligation with respect to
       Indebtedness of a third person (other than Indebtedness of a
       consolidated Subsidiary of such person or with respect to a consolidated
       Subsidiary of the Company other than Indebtedness of the Company), the

       Disqualified Capital Stock of such Person and its Subsidiaries on a
       consolidated basis; provided that if, during such period, such Person or
       any of its Subsidiaries shall have made any Asset Sales or Acquisitions,
       Consolidated Fixed Charges for such Person and its Subsidiaries for such
       period shall be adjusted to give pro forma effect to the Consolidated
       Fixed Charges directly attributable to the assets which are the subject
       of such Asset Sales or Acquisitions during such period.

               "Consolidated Interest Expense" means, with respect to any

       one-third of the amount of all lease





                                       11
<PAGE>   18
       payments (other than Capitalized Lease Obligations) paid, accrued and/or
       scheduled to be paid or accrued by such person and its Subsidiaries

       or as to which that Person is otherwise liable for reimbursement of

subfacility to the Company within the Commitment, in accordance with the terms
and conditions of Article III and as otherwise provided herein.

               (c)  As of the Closing Date, all Prior Credit shall be deemed to
be credit extended hereunder (i.e. loans thereunder shall be deemed to be Loans
hereunder and letters of credit issued thereunder shall be deemed to be Letters
of Credit issued

hereunder) and shall be subject to the terms and conditions of this Agreement
and shall be a utilization of the Commitment.

       2.02  Loan Accounts.  The Loans and the L/C Obligations shall be
evidenced by one or more accounts maintained by the Bank in the ordinary course
of business.  The accounts or records maintained by the Bank shall be prima
facie evidence of the amount of the Loans and L/C Obligations made by the Bank
to or for the account of the Company and the interest and payments thereon.
Any failure so to record or any error in doing so shall not, however, limit or
otherwise affect the obligation of the Company hereunder to pay any amount
owing with respect to the Loans or L/C Obligations.

       2.03  Procedure for Borrowing.

               (a)      Each Loan shall be made upon the irrevocable written
notice of the Company in the form of a Notice of Borrowing (which notice must
be received by the Bank prior to 9:00 a.m. (San Francisco time) (i) three
Business Days prior to the requested Borrowing date, in the case of Offshore
Rate Loans and CD Rate Loans, and (ii) on the requested Borrowing date, in the
case of Base Rate Loans, specifying:

                                (A)  the amount of the Loan, which shall be in
               an aggregate minimum principal amount of $500,000, in the case
               of Offshore Rate Loans and CD Rate Loans, or $100,000 for Base
               Rate Loans (provided that if there shall have been a partial
               assignment to an Assignee pursuant to Section 10.07, the minimum
               principal amount for Base Rate Loans shall be $500,000), or any
               integral multiple of $100,000 in excess thereof;

                                (B)  the requested Borrowing date, which shall 
               be a Business Day;

                                (C)  whether the Loan is to be an Offshore Rate
               Loan, a Base Rate Loan or a CD Rate Loan; and

                                (D)  the duration of the Interest Period
               applicable to the Loan included in such notice.  If the Notice
               of Borrowing shall fail to specify the duration of the Interest
               Period for any CD Rate Loan or Offshore Rate Loan, such Interest
               Period shall be 90 days or three months, respectively;

               (b)      After giving effect to any Loan, there shall not be
more than five different Interest Periods in effect.

       2.04  Conversion and Continuation Elections.

               (a)      The Company may upon irrevocable written notice to the
Bank in accordance with subsection 2.04(b):

                        (i)  elect to convert on any Business Day, any Base
       Rate Loan or Loans (or any part thereof in an aggregate amount not less
       than $500,000, or that is in an integral multiple of $100,000 in excess
       thereof) into an Offshore Rate Loan or CD Rate Loan or;

                        (ii)  elect to convert on the last day of the
       applicable Interest Period any Offshore Rate Loan or CD Rate Loan having
       an Interest Period maturing on such day (or any part thereof in an
       amount not less than $100,000, or that is in an integral multiple of
       $100,000 in excess thereof) into a Base Rate Loan; provided that if
       there shall have been a partial assignment to an Assignee pursuant to
       Section 10.07, the minimum principal amount which may be converted into
       Base Rate Loans shall be $500,000 or any integral multiple of $100,000
       in excess thereof; and provided, further, that after giving effect to
       any partial conversion of an Offshore Rate Loan or CD Rate Loan into a
       Base Rate Loan, the principal balance of such Offshore Rate Loan or CD
       Rate Loan not so converted shall be not less than $500,000; or

                        (iii)  elect to renew on the last day of the applicable
       Interest Period any Offshore Rate Loan or CD Rate Loan having an
       Interest Period maturing on such day (or any part thereof in an amount
       not less than $500,000, or that is in an integral multiple of $100,000
       in excess thereof);

provided, that if the amount of any CD Rate Loan or Offshore Rate Loan shall
have been reduced by payment, prepayment, or conversion of part thereof to be
less than $500,000, such CD Rate Loan or Offshore Rate Loan shall automatically
convert into a Base Rate Loan, and on and after such date the right of the
Company to convert such Loan into, an Offshore Rate Loan or a CD Rate Loan, as
the case may be, shall terminate.

               (b)      The Company shall deliver in writing a Notice of
Conversion/Continuation to be received by the Bank not later than 9:00 a.m.
(San Francisco time) at least (i) three Business Days in advance of the
Conversion Date or continuation date, if the Loans are to be converted into or
continued as Offshore Rate Loans or CD Rate Loans; and (ii) on the Conversion
Date or continuation date, if the Loans are to be converted into or renewed as
Base Rate Loans, specifying:





                                       32
<PAGE>   39
                                (A)      the proposed Conversion Date or
               continuation date;

                                (B)      the aggregate amount of Loans to be
               converted or renewed;

                                (C)      the nature of the proposed conversion
               or continuation; and

                                (D)      the duration of the requested Interest
               Period.

               (c)      If upon the expiration of any Interest Period
applicable to any CD Rate Loan or Offshore Rate Loan, the Company has failed to
select timely a new Interest Period to be applicable to such CD Rate Loan or
Offshore Rate Loan, as the case may be, or if any Default or Event of Default
shall then exist, the Company shall be deemed to have elected to convert such
CD Rate Loan or Offshore Rate Loan into a Base Rate Loan effective as of the
expiration date of such current Interest Period.

               (d)      Unless the Bank shall otherwise agree, during the
existence of a Default or Event of Default, the Company may not elect to have a
Loan converted into or continued beyond the end of the applicable Interest
Period as an Offshore Rate Loan or a CD Rate Loan.

               (e)      Notwithstanding any other provision contained in this
Agreement, after giving effect to any conversion or continuation of any Loans,
there shall not be more than five different Interest Periods in effect.

       2.05  Voluntary Termination or Reduction of Commitment.  The Company
may, upon not less than five Business Days' prior written notice to the Bank,
terminate the Commitment or permanently reduce the Commitment by an aggregate
minimum amount of $1,000,000 or any multiple of $100,000 in excess thereof (or
of the balance of the Commitment, if less); provided that no such reduction or
termination shall be permitted if, after giving effect thereto and to any
prepayments of the Loans made on the effective date thereof, the (i)
then-Effective Amount of the Loans plus L/C Obligations would exceed the amount
of the Commitment then in effect; or (ii) then-Effective Amount in respect of
L/C Obligations would exceed the L/C Commitment; provided, further, that once
reduced in accordance with this Section 2.05, the Commitment may not be
increased.  All accrued commitment fees to, but not including the effective
date of any reduction or termination of Commitment with respect to the portion
thereof being so reduced or terminated, shall be paid on





                                       33
<PAGE>   40
the effective date of such reduction or termination.  Any notice of commitment
reduction or termination shall specify to what extent (if any) to which any
such reduction shall be applied to reduce as well the L/C Commitment. Any
termination of all of the Commitment shall terminate as well the L/C
Commitment.

       2.06  Optional Prepayments. Subject to Section 4.04, the Company may, at
any time or from time to time, upon at least three Business Days' written
notice to the Bank in the case of Offshore Rate Loans or CD Rate Loans, or
notice given no later than 10:00 a.m. on the date of prepayment in the case of
Base Rate Loans, prepay Loans in whole or in part, in amounts of $500,000 or
any multiple of $100,000 in excess thereof in the case of Offshore Rate Loans
or CD Rate Loans, or in amounts of $100,000 or any multiple in excess of
$100,000 thereof in the case of Base Rate Loans.  Such notice of prepayment
shall specify the date and amount of such prepayment and whether such
prepayment is of Base Rate Loans, CD Rate Loans or Offshore Rate Loans, or any
combination thereof.  Such notice shall not thereafter be revocable by the
Company.  If such notice is given by the Company, the Company shall make such
prepayment and the payment amount specified in such notice shall be due and
payable on the date specified therein, together with accrued interest to each
such date on the amount prepaid and any amounts required pursuant to Section
4.04.

       2.07  Mandatory Prepayments; Mandatory Reductions.

               (a)      Change of Control.  No later than 45 days after the
Bank has received notice of a Change of Control pursuant to subsection 7.03(i)
(or upon and at any time after the occurrence of any Change of Control if the
Company is in default of its obligations to deliver such a notice), the Bank
may by notice to such effect to the Company (i) declare the Commitment
(including the L/C Commitment) to be terminated, whereupon the Commitment shall
forthwith be terminated, and (ii) declare an amount equal to the maximum
aggregate amount that is or at any time thereafter may become available for
drawing under any outstanding Letters of Credit (whether or not any beneficiary
shall have presented, or shall be entitled at such time to present, the drafts
or other documents required to draw under such Letters of Credit) to be
immediately due and payable, or demand that the Company Cash Collateralize the
L/C Obligations to the extent of outstanding and wholly or partially undrawn
Letters of Credit, whereupon the Company shall so Cash Collateralize the L/C
Obligations; and declare the unpaid principal amount of all outstanding Loans,
all interest accrued and unpaid thereon, and all other amounts owing or payable
hereunder or under any other Loan Document to be immediately due





                                       34
<PAGE>   41
and payable; without presentment, demand or protest, all of which are hereby
expressly waived by the Company.

               (b)      General.  Any prepayments pursuant to this Section 2.07
shall be applied first to any Base Rate Loans then outstanding and then to CD
Rate Loans and Offshore Rate Loans with the shortest Interest Periods
remaining.  All prepayments of Loans pursuant to this Section 2.07 shall be
made together with accrued interest to the date of such payment on the
principal amount repaid, together with any amounts payable under Section 4.04;
provided, that if any such prepayment would cause the Company to incur
Obligations pursuant to Section 4.04 with respect to CD Rate Loans or Offshore
Rate Loans, the Company may Cash Collateralize such CD Rate Loans or Offshore
Rate Loans until the last day of the Interest Period related thereto, at which
time such Cash Collateral shall be applied by the Bank to pay such Loans.

       2.08  Repayment.  The Company shall repay to the Bank in full on the
Revolving Termination Date the aggregate principal amount of the Loans
outstanding on such date.

       2.09  Interest.

               (a)      Subject to subsection 2.09(c), each Loan shall bear
interest on the outstanding principal amount thereof from the date when made at
a rate per annum equal to the Offshore Rate, the Base Rate or the CD Rate, as
the case may be, plus the Applicable Rate.

               (b)      Interest on each Loan shall be payable in arrears on
each Interest Payment Date.  Interest shall also be payable on the date of any
prepayment of Loans pursuant to Section 2.06 or 2.07 for the portion of the
Loans so prepaid and upon payment (including prepayment) in full thereof and,
during the existence of any Event of Default, interest shall be payable on
demand.

               (c)      While any Event of Default exists or after
acceleration, the Company shall pay interest (after as well as before entry of
judgment thereon to the extent permitted by law) on the principal amount of all
Obligations due and unpaid, at a rate per annum which is determined by adding
2% per annum to the Applicable Rate then in effect for such Loans and, in the
case of Obligations not subject to an Applicable Rate, at a rate per annum
equal to the Base Rate plus 2%; provided, however, that, on and after the
expiration of any Interest Period applicable to any Offshore Rate Loan or CD
Rate Loan outstanding on the date of occurrence of such Event of Default or
acceleration, the principal amount of such Loan shall, during the continuation
of





                                       35
<PAGE>   42
such Event of Default or after acceleration, bear interest at a rate per annum
equal to the Base Rate plus 2%.

       2.10  Commitment Fee.  The Company shall pay to the Bank a commitment
fee equal to the Applicable Rate per annum times the average daily unused
amount of the Commitment.  Such fee shall accrue from the Closing Date to the
later of (i) the Revolving Termination Date or (ii) the date that all Loans and
L/C Obligations outstanding on the Revolving Termination Date are paid in full,
and shall be due and payable quarterly in arrears on the last Business Day of
each calendar quarter commencing on the last day of the calendar quarter within
which the Closing Date occurs through the later of the dates referred to in
clauses (i) and (ii) above, with the final payment to be made on the later of
such dates.

       2.11  Computation of Fees and Interest.

               (a)      All computations of interest payable in respect of Base
Rate Loans at all times as the Base Rate is determined by the Bank's "reference
rate" shall be made on the basis of a year of 365 or 366 days, as the case may
be, and actual days elapsed.  All other computations of fees and interest under
this Agreement shall be made on the basis of a 360-day year and actual days
elapsed, which results in more interest being paid than if computed on the
basis of a 365-day year.  Interest and fees shall accrue during each period
during which interest or such fees are computed from the first day thereof to
the last day thereof.

               (b)      Any change in the interest rate on a Loan resulting
from a change in the Applicable Rate, Reserve Percentage, Eurocurrency Reserve
Percentage, or the Assessment Rate shall become effective as of the opening of
business on the day on which such change in the Applicable Rate, Reserve
Percentage, Eurocurrency Reserve Percentage, or the Assessment Rate becomes
effective.

               (c)      Each determination of an interest rate by the Bank
pursuant to any provision of this Agreement shall be conclusive and binding on
the Company in the absence of manifest error.

       2.12  Payments by the Company.

               (a)      All payments (including prepayments) to be made by the
Company on account of principal, interest, fees and other amounts required
hereunder shall be made without set-off or counterclaim; shall, except as
otherwise expressly provided herein, be made to the Bank at the Bank's Payment
Office, and shall be made in dollars and in immediately available funds, no





                                       36
<PAGE>   43
later than 11:00 a.m. (San Francisco time) on the date specified herein.  Any
payment which is received by the Bank later than 11:00 a.m. (San Francisco
time) shall be deemed to have been received on the immediately succeeding
Business Day and any applicable interest or fee shall continue to accrue.

               (b)      Whenever any payment hereunder shall be stated to be
due on a day other than a Business Day, such payment shall instead be due and
made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of interest or fees, as the case may
be; subject to the provisions set forth in the definition of "Interest Period"
herein.


                                  ARTICLE III

                             THE LETTERS OF CREDIT

       3.01  The Letter of Credit Subfacility.

               (a)      On the terms and conditions set forth herein, the Bank
agrees (i) from time to time on any Business Day during the period from the
Closing Date to the Revolving Termination Date to issue Letters of Credit for
the account of the Company (or for the account of any Subsidiary of the
Company, provided, that the applicable L/C Application shall be submitted
jointly and severally by the Company and its Subsidiary and the Company shall
be liable for all L/C Obligations with respect to such Letter of Credit, which
shall be deemed for all purposes hereof to be a Letter of Credit issued for the
account of such Company), and to amend or renew Letters of Credit previously
issued by it, in accordance with subsection 3.02(b), and (ii) to honor drafts
under the Letters of Credit; provided, that the Bank shall not be obligated to
Issue any Letter of Credit if as of the date of Issuance of such Letter of
Credit (A) the Effective Amount of all L/C Obligations plus the Effective
Amount of all Loans shall exceed the Commitment, or (B) the Effective Amount of
all L/C Obligations shall exceed the L/C Commitment.  Within the foregoing
limits, and subject to the other terms and conditions hereof, the Company's
ability to obtain Letters of Credit shall be fully revolving, and, accordingly,
the Company may, during the foregoing period, obtain Letters of Credit to
replace Letters of Credit which have expired or which have been drawn upon and
reimbursed.

               (b)      The Bank shall be under no obligation to Issue any
Letter of Credit if:





                                       37
<PAGE>   44
                        (i)  any order, judgment or decree of any Governmental
       Authority or arbitrator shall by its terms purport to enjoin or restrain
       the Bank from Issuing such Letter of Credit, or any Requirement of Law
       applicable to the Bank or any request or directive (whether or not
       having the force of law) from any Governmental Authority with
       jurisdiction over the Bank shall prohibit, or request that the Bank
       refrain from, the Issuance of letters of credit generally or such Letter
       of Credit in particular or shall impose upon the Bank with respect to
       such Letter of Credit any restriction, reserve or capital requirement
       (for which the Bank is not otherwise compensated hereunder) not in
       effect on the Closing Date, or shall impose upon the Bank any
       unreimbursed loss, cost or expense which was not applicable on the
       Closing Date and which the Bank in good faith deems material to it;

                        (ii)  the expiry date of any requested Letter of Credit
       is (A) more than 360 days after the date of Issuance, or (B) more than
       180 days after the Revolving Termination Date; provided, that any such
       Letter of Credit may contain an automatic renewal clause satisfactory to
       the Bank in its sole discretion;

                        (iii)  any requested Letter of Credit does not provide
       for drafts, or is not otherwise in form and substance acceptable to the
       Bank, or the Issuance of a Letter of Credit shall violate any applicable
       policies of the Bank; or

                        (iv)  any Letter of Credit is for the purpose of
       supporting the issuance of any letter of credit by any other Person or
       for the purpose of supporting any borrowed money debt.

       3.02  Issuance, Amendment and Renewal of Letters of Credit.

               (a)      Each Letter of Credit shall be issued upon the
irrevocable written request of the Company received by the Bank at least three
Business Days prior to the proposed date of issuance.  Each such request for
issuance of a Letter of Credit shall be by facsimile, confirmed promptly in an
original writing, in the form of an L/C Application, and shall specify in form
and detail satisfactory to the Bank: (i) the proposed date of issuance of the
Letter of Credit (which shall be a Business Day); (ii) the face amount of the
Letter of Credit; (iii) the expiry date of the Letter of Credit; (iv) the name
and address of the beneficiary thereof; (v) the documents to be presented by
the beneficiary of the Letter of Credit in case of any drawing thereunder; (vi)
the full text of any certificate to be





                                       38
<PAGE>   45
presented by the beneficiary in case of any drawing thereunder; and (vii) such
other matters relating to such Letter of Credit as the Bank may reasonably
require.

               (b)      From time to time while a Letter of Credit is
outstanding and prior to the Revolving Termination Date, the Bank will, upon
the written request of the Company received by the Bank at least three Business
Days prior to the proposed date of amendment, amend any Letter of Credit issued
by it.  Each such request for amendment of a Letter of Credit shall be made by
facsimile, confirmed promptly in an original writing, made in the form of an
L/C Amendment Application and shall specify in form and detail satisfactory to
the Bank:  (i) the Letter of Credit to be amended; (ii) the proposed date of
amendment of the Letter of Credit (which shall be a Business Day); (iii) the
nature of the proposed amendment; and (iv) such other matters relating to such
proposed amendment as the Bank may reasonably require.  The Bank shall be under
no obligation to amend any Letter of Credit if:  (A) the Bank would have no
obligation at such time to issue such Letter of Credit in its amended form
under the terms of this Agreement; or (B) the beneficiary of any such Letter of
Credit does not accept the proposed amendment to the Letter of Credit.

               (c)      This Agreement shall control in the event of any
conflict with any L/C-Related Document (other than any Letter of Credit).

       3.03  Drawings and Reimbursements.  In the event of any request for a
drawing under a Letter of Credit by the beneficiary or transferee thereof, the
Bank will promptly notify the Company.  The Company may, subject to
satisfaction of all conditions to borrowing set forth in this Agreement,
convert the amount of each drawing into Loans consisting of Base Rate Loans
(which conversion shall be deemed to be a new Credit Extension) in accordance
with the procedures for borrowing set forth in Section 2.03.  With respect to
any unreimbursed drawing which is not converted into Loans consisting of Base
Rate Loans to the Company in whole or in part, because of the Company's failure
to satisfy the conditions set forth in Section 5.03 or for any other reason,
the Company shall reimburse the Bank prior to 11:00 a.m. (San Francisco time),
on each date that any amount is paid by the Bank under any Letter of Credit, in
an amount equal to the amount so paid by the Bank.  Such reimbursement
obligations in respect of drawings, if not paid when due, shall accrue interest
at the Base Rate plus 2%.

       3.04  Obligations Absolute.  The obligations of the Company under this
Agreement and any L/C-Related Document to reimburse the Bank for a drawing
under a Letter of Credit, shall be





                                       39
<PAGE>   46
unconditional and irrevocable, and shall be paid strictly in accordance with
the terms of this Agreement and each such other L/C-Related Document under all
circumstances, including the following:

                        (i)  any lack of validity or enforceability of this
       Agreement or any L/C-Related Document;

                        (ii)  any change in the time, manner or place of
       payment of, or in any other term of, all or any of the obligations of
       the Company or any Subsidiary of the Company in respect of any Letter of
       Credit or any other amendment or waiver of or any consent to departure
       from all or any of the L/C-Related Documents;

                        (iii)  the existence of any claim, set-off, defense or
       other right that the Company or any Subsidiary of the Company may have
       at any time against any beneficiary or any transferee of any Letter of
       Credit (or any Person for whom any such beneficiary or any such
       transferee may be acting), the Bank or any other Person, whether in
       connection with this Agreement, the transactions contemplated hereby or
       by the L/C-Related Documents or any unrelated transaction;

                        (iv)  any draft, demand, certificate or other document
       presented under any Letter of Credit proving to be forged, fraudulent,
       invalid or insufficient in any respect or any statement therein being
       untrue or inaccurate or inaccurate in any respect; or any loss or delay
       in the transmission or otherwise of any document required in order to
       make a drawing under any Letter of Credit;

                        (v)  any payment by the Bank under any Letter of Credit
       against presentation of a draft or certificate that does not strictly
       comply with the terms of any Letter of Credit (provided that the

       any of the obligations of the Company or any Subsidiary of the Company
       in respect of any Letter of Credit; or

                        (vii)  to the extent permitted by applicable law, any
       other circumstance or happening whatsoever, whether or not similar to
       any of the foregoing, including any other circumstance that might
       otherwise constitute a defense available to, or a discharge of, the
       Company or a guarantor.

       3.05  Cash Collateral Pledge.  Upon (i) the request of the Bank, if, as
of the Revolving Termination Date, any Letters of Credit may for any reason

annum of the average daily maximum amount available to be drawn on the
outstanding standby Letters of Credit, computed on a quarterly basis in arrears
on the last Business Day of each calendar quarter based upon standby Letters of
Credit outstanding for that quarter, as calculated by the Bank.  Such letter of
credit fee shall be due and payable quarterly in arrears on the last Business
Day of each calendar quarter during which standby Letters of Credit are
outstanding, commencing on the first such quarterly date to occur after the
Closing Date, through the Revolving Termination Date (or such later date upon
which the outstanding standby Letters of Credit shall expire), with the final
payment to be made on the Revolving Termination Date (or such later expiration
date).

               (b)  The Company shall pay to the Bank upon the issuance of each
commercial Letter of Credit or such other times as the Bank may advise, such
fees as the Bank may customarily impose with respect to commercial letters of
credit similar to such commercial Letter of Credit.

               (c)  The Company shall pay to the Bank from time to time on
demand the normal issuance, presentation, amendment and other processing fees,
and other standard costs and charges, of the Bank relating to letters of credit
as from time to time in effect.

                                   ARTICLE IV

                     TAXES, YIELD PROTECTION AND ILLEGALITY

       4.01  Taxes.

               (a)      (i)  If any taxes (other than taxes on net income (A)
       imposed by the country or any subdivision of the country in which the
       Bank's principal office or actual lending office is located and (B)
       measured by the United States taxable income the Bank would have
       received if all payments under or in respect of this Agreement and any
       instrument or agreement required hereunder were exempt from taxes levied
       by the Company's country) are at any time after the Closing Date imposed
       on any payments under or in respect of this Agreement or any instrument
       or agreement required hereunder including, but not limited to, payments
       made pursuant to this Section 4.01, the Company shall pay all such taxes
       and shall also pay to the Bank, at the time interest is paid, all
       additional amounts which the Bank specifies as necessary to preserve the
       after-tax yield the Bank would have received if such taxes had not been
       imposed.

                        (ii)  The additional amounts necessary to preserve the
       after-tax yield the Bank would have received if such taxes had not been
       imposed shall be calculated pursuant to the formula:

                                               (w)(t)(i)
                                         y = ----------------
                                                 1-w-t

       where the terms are defined as follows:

               y =      additional payment to be made to Bank
               w =      withholding tax rate levied by foreign government
               t =      the Bank's combined Federal and state tax rate
               i =      stated interest to be paid on credit (base rate
                        plus quoted spread)

               1 =      one





                                       42
<PAGE>   49
       (b)     The Company will provide the Bank with original tax receipts,
notarized copies of tax receipts, or such other documentation as will prove
payment of tax in a court of law applying the United States Federal Rules of
Evidence, for all taxes paid by the Company pursuant to subsection 4.01(a)
above.  The Company will deliver receipts to the Bank within 30 days after the
due date for the related tax.

       (c)     If the Company is required to pay additional amounts to the Bank
pursuant to subsection 4.01(a), then the Bank shall use its reasonable best
efforts (consistent with legal and regulatory restrictions) to change the
jurisdiction of its Lending Office so as to eliminate any such additional
payment by the Company which may thereafter accrue if such change in the
judgment of the Bank is not otherwise disadvantageous to the Bank.

       4.02  Illegality.

               (a)      If the Bank shall determine that the introduction of
any Requirement of Law, or any change after the Closing Date in any Requirement
of Law or in the interpretation or administration thereof, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for the Bank or its Lending Office to make Offshore Rate
Loans, then, on notice thereof by the Bank to the Company, the obligation of
the Bank to make Offshore Rate Loans shall be suspended until the Bank shall
have notified the Company that the circumstances giving rise to such
determination no longer exists.

               (b)      If the Bank shall determine that it is unlawful to
maintain any Offshore Rate Loan, the Company shall prepay in full all Offshore
Rate Loans of the Bank then outstanding, together with interest accrued
thereon, either on the last day of the Interest Period thereof if the Bank may
lawfully continue to maintain such Offshore Rate Loans to such day, or
immediately, if the Bank may not lawfully continue to maintain such Offshore
Rate Loans, together with any amounts required to be paid in connection
therewith pursuant to Section 4.04.

       4.03  Increased Costs and Reduction of Return.

               (a)      If the Bank shall determine that, due to either (i) the
introduction of or any change (other than any change by way of imposition of or
increase in reserve requirements included in the calculation of the CD Rate or
the Offshore Rate) in or in the interpretation of any law or regulation after
the Closing Date or (ii) the compliance with any guideline or request from any
central bank or other Governmental Authority





                                       43
<PAGE>   50
after the Closing Date (whether or not having the force of law), there shall be
any increase in the cost to the Bank of agreeing to make or making, funding or
maintaining any Offshore Rate Loans or CD Rate Loans, then the Company shall be
liable for, and shall from time to time, upon demand therefor by the Bank pay
to the Bank additional amounts as are sufficient to compensate the Bank for
such increased costs, not later than 30 days following demand therefor.

               (b)      If the Bank shall have determined that (i) the
introduction of any Capital Adequacy Regulation, (ii) any change in any Capital
Adequacy Regulation, (iii) any change in the interpretation or administration
of any Capital Adequacy Regulation by any central bank or other Governmental
Authority charged with the interpretation or administration thereof, or (iv)
compliance by the Bank (or its Lending Office) or any corporation controlling
the Bank, with any Capital Adequacy Regulation, in each case, after the Closing
Date; affects or would affect the amount of capital required or expected to be
maintained by the Bank or any corporation controlling the Bank and (taking into
consideration the Bank's or such corporation's policies with respect to capital
adequacy and the Bank's desired return on capital) determines that the amount
of such capital is increased as a consequence of its loans, credits or
obligations under this Agreement, then, upon demand of the Bank the Company
shall upon demand pay to the Bank, from time to time as specified by the Bank,
additional amounts sufficient to compensate the Bank for such increase, not
later than 30 days following demand therefor.

       4.04  Funding Losses.  The Company agrees to reimburse the Bank and to
hold the Bank harmless from any actual loss or expense which the Bank may
sustain or incur as a consequence of:

               (a)      the failure of the Company to make any payment or
mandatory prepayment of principal of any Offshore Rate Loan or CD Rate Loan
(including payments made after any acceleration thereof);

               (b)      the failure of the Company to borrow, continue or
convert a Loan after the Company has given (or is deemed to have given) a
Notice of Borrowing or a Notice of Conversion/ Continuation;

               (c)      the failure of the Company to make any prepayment after
the Company has given a notice in accordance with Section 2.06 or 2.07;

               (d)      the prepayment (including pursuant to Section 2.07) by
the Company of an Offshore Rate Loan or a CD





                                       44
<PAGE>   51
Rate Loan on a day which is not the last day of the Interest Period with
respect thereto; or

               (e)      the conversion by the Company pursuant to Section 2.04
of any Offshore Rate Loan or CD Rate Loan to a Base Rate Loan on a day that is
not the last day of the respective Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Loans or CD Rate Loans
hereunder or from fees payable to terminate the deposits from which such funds
were obtained.  Solely for purposes of calculating amounts payable by the
Company to the Bank under this Section 4.04 and under subsection 4.03(a), (i)
each Offshore Rate Loan (and each related reserve, special deposit or similar
requirement) shall be conclusively deemed to have been funded at the IBOR used
in determining the Offshore Rate for such Offshore Rate Loan by a matching
deposit or other borrowing in the interbank eurodollar market for a comparable
amount and for a comparable period, whether or not such Offshore Rate Loan is
in fact so funded, and (ii) each CD Rate Loan made (and each related reserve,
special deposit or similar requirement) shall be conclusively deemed to have
been funded at the Certificate of Deposit Rate used in determining the CD Rate
for such CD Rate Loan by the issuance of its certificate of deposit in a
comparable amount and for a comparable period, whether or not such CD Rate Loan
is in fact so funded.

       4.05  Inability to Determine Rates.  If the Bank shall have determined
that for any reason adequate and reasonable means do not exist for ascertaining
the Offshore Rate or the CD Rate for any requested Interest Period with respect
to a proposed Offshore Rate Loan or CD Rate Loan or that the Offshore Rate or
the CD Rate applicable pursuant to subsection 2.09(a) for any requested
Interest Period with respect to a proposed Offshore Rate Loan or CD Rate Loan
does not adequately and fairly reflect the cost to the Bank of funding such
Loan, the Bank will forthwith give notice of such determination to the Company.
Thereafter, the obligation of the Bank to make or maintain CD Rate Loans or
Offshore Rate Loans, as the case may be, hereunder shall be suspended until the
Bank revokes such notice in writing.  Upon receipt of such notice, the Company
may revoke any Notice of Borrowing or Notice of Conversion/Continuation then
submitted by it.  If the Company does not revoke such notice, the Bank shall
make, convert or continue the Loans, as proposed by the Company, in the amount
specified in the applicable notice submitted by the Company, but such Loans
shall be made, converted or continued as Base Rate Loans instead of CD Rate
Loans or Offshore Rate Loans, as the case may be.





                                       45

         4.06  Certificate of Bank.  The Bank, if claiming reimbursement or
compensation pursuant to this Article IV, shall deliver to the Company a
certificate setting forth in reasonable detail the amount payable to the Bank
hereunder and such certificate shall be prima facie evidence of such amount.
If the Bank fails to notify the Company that the Bank intends to claim any such
reimbursement or compensation within one year after the Bank has knowledge of
its claim therefor, the Company shall not be obligated to compensate the Bank
for the amount of the Bank's claim accruing prior to the date which is one year
before the date on which the Bank first notifies the Company that it intends to
make such claim; it being understood that the calculation of the actual amounts
may not be possible within such period and the Bank may provide such
calculation as soon as reasonably practicable thereafter without affecting or
limiting the Company's payment obligations hereunder.

         4.07  Survival.  The agreements and obligations of the Company in this
Article IV shall survive the payment of all other Obligations.


                                   ARTICLE V

Company Document to which the Company is party, have been duly authorized by

requirements for qualification may be satisfied by adopting retroactive
amendments under Section 401(b) of the Code and the regulations thereunder or

the Company, nothing has occurred which would cause the loss of such

specifically disclosed in Schedule 6.15, the Company or its Subsidiaries own or
are licensed or otherwise have the right to use (or could obtain ownership of,

trademarks, service marks, trade names, copyrights, and other intellectual
property rights and licenses to the foregoing that are reasonably necessary for

statements furnished by any Responsible Officer to the Bank pursuant to any
provision of this Agreement, taken together with all such documents,
certificates and written statements, do not contain any untrue statement of a

payable by the Company hereunder shall be determined as if the Bank had not
sold such participation, except that if amounts outstanding under this
Agreement are due and unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each Participant
shall be deemed to have the right of set-off in respect of its participating
interest in amounts owing under this Agreement to the same extent as if the
amount of its participating interest were owing directly to it as the Bank
under this Agreement.  The Company shall not be required to incur any expense
in connection with any such participation.

                 (c)      The Bank agrees to take normal and reasonable
precautions and exercise due care to maintain the confidentiality of all
non-public information provided to it by the Company or any Subsidiary of the
Company in connection with this Agreement or any other Loan Document, and
neither it nor any of its Affiliates shall use any such information for any
purpose or in any manner other than as contemplated by this Agreement; except
to the extent such information (i) was or





                                       83
<PAGE>   90

becomes generally available to the public other than as a result of a
disclosure by the Bank, or (ii) was or becomes available on a non-confidential
basis from a source other than the Company, provided that such source is not
bound by a confidentiality agreement with the Company known to the Bank;
provided, that the Bank may disclose such information (A) at the request or
pursuant to any requirement of any Governmental Authority to which the Bank is
subject or in connection with an examination of the Bank by any such authority;
(B) pursuant to subpoena or other court process; (C) when required to do so in
accordance with the provisions of any applicable Requirement of Law; (D) to the
Bank's independent auditors and other professional advisors; (E) to the extent
reasonably required in connection with any litigation or proceeding to which
the Bank or any of its Affiliates may be party; and (F) to the extent
reasonably required in connection with the exercise of any remedy hereunder or
under any other Loan Document; and provided, further that in the event of a
disclosure pursuant to clause (B), (C) or (E) of this subsection, the Bank
shall, unless prohibited from doing so by any applicable Requirement of Law,
give notice to the Company prior to any such disclosure and shall use
commercially reasonable efforts to cooperate with the Company (at no cost to
the Bank) to seek a protective order with respect to the information requested
to be disclosed.  Notwithstanding the foregoing, the Company authorizes the
Bank to disclose to any Participant or Assignee and to any prospective
Participant or Assignee, such financial and other information in the Bank's
possession concerning the Company or its Subsidiaries which has been delivered
to the Bank pursuant to this Agreement or which has been delivered to the Bank
by the Company in connection with the Bank's credit evaluation of the Company
prior to entering into this Agreement; provided that, unless otherwise agreed
by the Company, such Participant or Transferee agrees in writing to the Bank to
keep such information confidential to the same extent required of the Bank
hereunder.

         10.08  Set-off.  In addition to any rights and remedies of the Bank
provided by law, if an Event of Default exists, the Bank is authorized at any
time and from time to time, without prior notice to the Company, any such
notice being waived by the Company to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held by, and other indebtedness at any time
owing to, the Bank to or for the credit or the account of the Company against
any and all Obligations of the Company owing to the Bank, now or hereafter
existing, irrespective of whether or not the Bank shall have made demand under
this Agreement or any Loan Document.  The Bank agrees promptly to notify the
Company after any such set-off and application made by the Bank; provided,
however, that the





                                       84
<PAGE>   91

failure to give such notice shall not affect the validity of such set-off and
application.  The rights of the Bank under this Section 10.08 are in addition
to the other rights and remedies (including other rights of set-off) which the
Bank may have.

         10.09  Automatic Debits of Fees.  With respect to any facility fee or
other regularly scheduled fee or cost, due and payable to the Bank hereunder by
the Company, the Company hereby authorizes the Bank, until such authorization
is revoked by the Company in writing, to debit any deposit account of the
Company with the Bank in an amount such that the aggregate amount debited from
all such deposit accounts does not exceed such fee or cost due from the
Company.  If there are insufficient funds in such deposit accounts to cover the
amount of the fee or other cost or expense then due, such debits will be
reversed (in whole or in part, in the Bank's sole discretion) and such amount
not debited shall be deemed to be unpaid.  No such debit under this Section
10.09 shall be deemed a setoff.

         10.10  Counterparts.  This Agreement may be executed by one or more of
the parties to this Agreement in any number of separate counterparts, each of
which, when so executed, shall be deemed an original, and all of said
counterparts taken together shall be deemed to constitute but one and the same
instrument.

         10.11  Severability.  The illegality or unenforceability of any
provision of this Agreement or any instrument or agreement required hereunder
shall not in any way affect or impair the legality or enforceability of the
remaining provisions of this Agreement or any instrument or agreement required
hereunder.

         10.12  No Third Parties Benefited.  This Agreement is made and entered
into for the sole protection and legal benefit of the Company and the Bank and
their permitted successors and assigns, and no other Person shall be a direct
or indirect legal beneficiary of, or have any direct or indirect cause of
action or claim in connection with, this Agreement or any of the other Loan
Documents.  Neither the Bank nor, except to the extent expressly set forth
herein, the Company (or any of its Subsidiaries) shall have any obligation to
any Person not a party to this Agreement or other Loan Documents.

         10.13  Time.  Time is of the essence as to each term or provision of
this Agreement and each of the other Loan Documents.

         10.14   Governing Law and Jurisdiction.

                 (a)      THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA; PROVIDED THAT THE BANK
SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.


                 (b)      SUBJECT TO SECTION 10.15, ANY LEGAL ACTION OR
PROCEEDING WITH RESPECT TO THIS AGREEMENT AND ANY OTHER LOAN DOCUMENTS MAY BE
BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE UNITED STATES FOR
THE NORTHERN DISTRICT OF CALIFORNIA, AND BY EXECUTION AND DELIVERY OF THIS
AGREEMENT, EACH OF THE COMPANY AND THE BANK CONSENTS, FOR ITSELF AND IN RESPECT
OF ITS PROPERTY, TO THE JURISDICTION OF THOSE COURTS.  SUBJECT TO SECTION
10.15, EACH OF THE COMPANY AND THE BANK IRREVOCABLY WAIVES ANY OBJECTION,
INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM
NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY
ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY
DOCUMENT RELATED HERETO.  THE COMPANY AND THE BANK EACH WAIVE PERSONAL SERVICE
OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER
MEANS PERMITTED BY CALIFORNIA LAW.

         10.15   Arbitration; Reference.

                 (a)      Mandatory Arbitration.  Any controversy or claim
between or among the parties, including but not limited to those arising out of
or relating to this Agreement or any agreements or instruments relating hereto
or delivered in connection herewith and any claim based on or arising from an
alleged tort, shall at the request of any party be determined by arbitration.
The arbitration shall be conducted in accordance with the United States
Arbitration Act (Title 9, U.S. Code), notwithstanding any choice of law
provision in this Agreement, and under the Commercial Rules of the American
Arbitration Association ("AAA").  The arbitrator(s) shall give effect to
statutes of limitation in determining any claim.  Any controversy concerning
whether an issue is arbitrable shall be determined by the arbitrator(s).
Judgment upon the arbitration award may be entered in any court having
jurisdiction.  The institution and maintenance of an action for judicial relief
or pursuit of a provisional or ancillary remedy shall not constitute a waiver
of the right of any party, including the plaintiff, to submit the controversy
or claim to arbitration if any other party contests such action for judicial
relief.

                 (b)      Judicial Reference.  At the request of any party a
controversy or claim which is not submitted to arbitration as provided and
limited in subsection (a) of this Section shall be determined by a reference in
accordance with California Code of





                                       86
<PAGE>   93
Civil Procedure Section 638 et seq.  If such an election is made, the parties
shall designate to the court a referee or referees selected under the auspices
of the AAA in the same manner as arbitrators are selected in AAA-sponsored
proceedings.  The presiding referee of the panel, or the referee if there is a
single referee, shall be an active attorney or retired judge.  Judgment upon
the award rendered by such referee or referees shall be entered in the court in
which such proceeding was commenced in accordance with California Code of Civil
Procedure Sections 644 and 645.

                 (c)      Provisional Remedies and Setoff.  No provision of
this Section shall limit the right of any party to this Agreement to exercise
the right of setoff, or to seek or obtain provisional or ancillary remedies
from a court of competent jurisdiction before, after, or during the pendency of
any arbitration or other proceeding.  The exercise of a remedy does not waive
the right of either party to resort to arbitration or reference.

         10.16  Entire Agreement.  This Agreement, together with the other Loan
Documents, embodies the entire agreement and understanding between the Company
and the Bank, and supersedes all prior or contemporaneous Agreements and
understandings of such Persons, verbal or written, relating to the subject
matter hereof and thereof.

                                   LITIGATION


1.      In May, 1996, the Company received notice from the Bureau of
        Competition of the Federal Trade Commission ("FTC") that the FTC staff
        is conducting a non-public investigation to determine whether certain
        manufacturers of lightweight telephone headsets may be engaged in
        anticompetitive practices in violation of Section 5 of the Federal Trade
        Commission Act. The Company has not been notified that it is a
        particularized subject of the investigation. There can be no assurance
        that the Company will not become a particularized subject of the
        investigation, that the FTC staff or the FTC itself will not proceed to
        a full public investigation in this matter, or that the outcome of any
        public investigation will not have a Material Adverse Effect.

To Bank of America National Trust
  and Savings Association
555 California Street, 41st Floor
San Francisco, CA  94104

         RE:     PLANTRONICS, INC. CREDIT AGREEMENT


Ladies and Gentlemen:

         We have acted as special counsel for Plantronics, Inc., a Delaware
corporation (the "Company"), in connection with the execution and delivery of
(i) the Credit Agreement, dated as of February 19, 1997 (the "Credit
Agreement"), between the Company and Bank of America National Trust and Savings
Association (the "Bank") and (ii) forms of the Application and Agreement for
Commercial Letter of Credit, Application for Amendment to Commercial Letter of
Credit, Application and Agreement for Standby Letter of Credit, and Application
for Amendment to Standby Letter of Credit (collectively, the "L/C
Applications," and, together with the Credit Agreement, the "Loan Documents").

         This opinion is provided to the Bank as required pursuant to Section
5.01(f) of the Credit Agreement.  Terms defined in the Credit Agreement and
used without other definition herein shall have the respective meanings
assigned, directly or indirectly by reference, to such terms in the Credit
Agreement, and terms used herein and not defined herein or in the Credit
Agreement shall have the respective meanings assigned to such terms in the
Uniform Commercial Code as in effect in the State of California on the date
hereof (the "UCC").

         In connection with this opinion, we have examined:

          (i)    executed copies of the Credit Agreement;

         (ii)    unexecuted forms of the L/C Applications, excluding the terms
and conditions interlined on the reverse side thereof, as delivered to us for
review;

Bank of America National Trust
  and Savings Association
As of February 19, 1997
Page 2



        (iii)    the Certificate of Incorporation and Bylaws of the Company, as
amended to date;

         (iv)    records of proceedings, consisting of draft minutes of a
meeting of the Board of Directors of the Company, during or by which
resolutions were adopted relating to matters covered by this opinion not yet
approved by the Board;

          (v)    the respective certificates of the Secretary and certain
officers of the Company as to certain factual matters (copies of which have
been delivered to the Bank pursuant to Sections 5.01(b), (c) and (e) of the
Credit Agreement); and

         (vi)    each of the agreements listed on Annex A hereto (the "Reviewed
Agreements").

         In addition, we have made such other investigations as we have deemed
necessary to enable us to render the opinions hereinafter set forth.  We advise
you that, as to all matters of fact, we have relied upon such examination and
investigation, and the representations and warranties of the Company contained
in the aforedescribed certificates, Article VI of the Credit Agreement (but
only to the extent such representations and warranties address factual matters)
and the Certificate appended hereto as Annex B (but only to the extent such
Certificate addresses factual matters).  We have assumed (a) the genuineness of
all signatures of persons (other than representatives of the Company) signing
the Loan Documents; (b) the authenticity of all documents submitted to us as
originals (c) the conformity to authentic original documents of all documents
submitted to us as certified, conformed or photostatic copies, and (d) except
as specifically covered in the opinions set forth below, the due authorization,
execution, and delivery on behalf of the respective parties thereto of
documents referred to herein and the legal, valid and binding effect thereof on
such parties.

         As used in this opinion, the expression "to our knowledge" or "known
to us" with reference to matters of fact means that during the course of our
representation of the Company in connection with the Loan Documents no
information has come to the attention of the attorneys of our firm involved in
this engagement which would give the actual knowledge of the existence or
absence of such facts; however, except to the extent expressly set forth
herein, we have made no independent investigation to determine the existence or
absence of such facts, and any limited inquiry undertaken by us during the
preparation of this opinion should not be regarded as such an investigation.
No inference as to our knowledge of the existence or absence of such facts
should be drawn from the fact of our representation of the Company.

         Based upon the foregoing, and further subject to the exceptions,
limitations, qualifications and assumptions, set forth below, we hereby advise
you that in our opinion:





<PAGE>   120
Bank of America National Trust
  and Savings Association
As of February 19, 1997
Page 3




                 1.       The Company has been duly incorporated and is validly
         existing and in good standing under the laws of its jurisdiction of
         incorporation.  The Company has the corporate power and authority to
         own and operate (or lease, as the case may be) its properties, to
         conduct the business in which it is currently engaged and to execute,
         deliver and perform its obligations under the Loan Documents.  The
         Company is qualified to do business as a foreign corporation in each
         jurisdiction wherein the ownership or leasing of properties or the
         conduct of its business renders such qualification necessary, except
         insofar as the failure to be so qualified would not have a Material
         Adverse Effect.  The jurisdictions in which the Company is qualified
         to do business are listed on Schedule 1 to Annex B hereto.

                 2.       The Loan Documents and the Credit Extensions pursuant
         to the Credit Agreement have been duly authorized by the Company and
         no further corporate action is required in connection therewith.  The
         execution and delivery of the Loan Documents by the Company and the
         due performance by the Company of its obligations thereunder do not
         and will not (i) violate or be in conflict with the Company's Articles
         of Incorporation or Bylaws or any law or regulation having
         applicability to the Company, or (ii) to our knowledge, violate,
         contravene or result in the creation of a Lien upon any of the assets
         or properties of the Company under, any material judgment, decree,
         injunction, writ or order of any court, or any arbitrator or other
         Governmental Authority, having jurisdiction over the Company or its
         properties or by which the Company may be bound.  No material consent,
         approval, authorization, registration or filing with any Governmental
         Authority which has not been obtained is required in connection with
         the execution, delivery or performance by the Company of the Loan
         Documents, except as contemplated thereby.

                 3.       The Loan Documents (except the unexecuted L/C
         Applications) have been duly executed and delivered by the Company.
         Each of the Loan Documents (other than the unexecuted L/C
         Applications) constitutes the legal, valid and binding obligation of
         the Company, enforceable against the Company in accordance with their
         respective terms.  The unexecuted L/C Applications, when duly executed
         and delivered, will constitute the legal, valid and binding
         obligations of the Company, enforceable against the Company in
         accordance with their respective terms.

                 4.       To our knowledge, there are no actions, suits, or
         proceedings pending, or,  threatened, against the Company before any
         court, regulatory agency or administrative agency, at law or in
         equity, in arbitration or before any Governmental Authority which seek
         to restrain





<PAGE>   121
Bank of America National Trust
  and Savings Association
As of February 19, 1997
Page 4



         the Company's performance of its obligations under the Loan Documents
         or which would reasonably be expected to have a Material Adverse
         Effect.

                 5.       To our knowledge, there are no governmental licenses,
         authorizations, consents or approvals required in order for the
         Company to own its assets and carry on its business as presently
         conducted, the failure to obtain which would reasonably be expected to
         have a Material Adverse Effect, which the Company has not obtained.

                 6.       The Credit Agreement, the Credit Extensions proposed
         to be made thereunder, the other Loan Documents and the performance by
         the Company of its obligations thereunder do not and will not violate
         or conflict with, constitute a default under or result in the
         termination of, accelerate the performance required by, or result in
         the creation of any Lien upon the assets or properties of the Company
         (except as contemplated by the Loan Documents) under, any Reviewed
         Agreement.

                 7.       The Company is not (a) an "investment company,"
         within the meaning of the Investment Company Act of 1940, as amended,
         nor (b) subject to the regulation under the Public Utility Holding
         Company Act of 1935, the Federal Power Act or any California public
         utilities code.

                 8.       To our knowledge, the Company does not intend to use
         the proceeds of any extension of credit under the Credit Agreement for
         the purpose of purchasing "margin stock" within the meaning of
         Regulations G, T, U and X of the Board of Governors of the Federal
         Reserve System.

         The foregoing opinions are subject to the exceptions, limitations,
qualifications and assumptions set forth below.

         A.      We are admitted to practice law only in the State of
                 California.  We express no opinion as to any matter relating
                 to laws of any jurisdiction other than the laws of the State
                 of California, the statutes comprising the General Corporation
                 Laws of the State of Delaware and the federal laws of the
                 United States, as such are in effect on the date hereof.  For
                 purposes of our review of the Reviewed Agreements, we have
                 assumed that the laws governing such Reviewed Agreements
                 (including the effect and appropriate interpretation thereof)
                 are identical in all relevant respects to the laws of the
                 State of California.

         B.      We express no opinion as to (i) the effect of any bankruptcy,
                 insolvency, reorganization, arrangement, moratorium or other
                 similar laws relating to or affecting the rights of creditors
                 generally including, without limitation, the effect of
                 statutory or other laws regarding fraudulent transfers or
                 conveyances or preferential transfers, or (ii) the effect of
                 general principles of equity, including without limitation,
                 concepts of materiality, reasonableness, good faith and fair
                 dealing, and the possible unavailability of specific
                 performance, injunctive relief or other equitable relief,
                 whether considered in a proceeding in equity or at law.

         C.      We express no opinion (i) regarding the rights or remedies
                 available to any party for violations or breaches of any
                 provisions which are immaterial or for violations or breaches
                 of any provisions the enforcement of which a court determines
                 would be unreasonable under the then existing circumstances,
                 (ii) regarding the rights or remedies available to any party
                 insofar as such party may take discretionary action which is
                 arbitrary, unreasonable or capricious, or is not taken in good
                 faith or in a commercially reasonable manner, whether or not
                 such action is permitted under the Credit Agreement, or (iii)
                 as to the effect of the exercise of judicial discretion,
                 whether in a proceeding in equity or at law.

         D.      We express no opinion as to the legality, validity, binding
                 nature or enforceability of (i) provisions in any Loan
                 Document providing for the payment or reimbursement of costs
                 or expenses or indemnifying a party, to the extent such
                 provisions may be held to be unreasonable in amount,
                 unenforceable as contrary to public policy, (ii) provisions
                 regarding the Bank's ability to collect attorneys' fees and
                 costs in an action involving any Loan Document, if the Bank is
                 not the prevailing party in such action (we call your
                 attention to the effect of Section 1717 of the California
                 Civil Code, which provides that, where a contract permits one
                 party thereto to recover attorneys' fees, the prevailing party
                 in any action to enforce any provision of the contract shall
                 be entitled to recover its reasonable attorneys' fees) or
                 (iii) provisions of any Loan Document imposing penalties or
                 forfeitures, late payment charges or any increase in interest
                 rate, upon delinquency in payment or the occurrence of a
                 default to the extent they constitute a penalty or forfeiture
                 or are otherwise contrary to public policy.

         E.      We express no opinion with respect to the legality, validity,
                 binding nature or enforceability of (i) any vague or broadly
                 stated waivers including, without limitation, the waivers of
                 diligence, presentment, demand, protest or notice, (ii) any
                 waivers or

Bank of America National Trust
  and Savings Association
As of February 19, 1997
Page 6



                 consents (whether or not characterized as a waiver or consent
                 in the relevant Loan Document) relating to the rights of the
                 Company or duties owing to it existing as a matter of law,
                 including, without limitation, waivers of the benefits of
                 statutory or constitutional provisions, to the extent such
                 waivers or consents are found by California courts to be
                 against public policy or which are ineffective pursuant to
                 California statutes and judicial decisions or (iii) any
                 waivers of any statute of limitations to the extent such
                 waivers are in excess of four years beyond the statutory
                 period.

         F.      We express no opinion as to the effect of judicial decisions
                 and statutes limiting the enforceability of provisions
                 requiring payment of additional consideration or a higher rate
                 of interest upon prepayment, late payment, maturity, default
                 or a lender's election to accelerate a loan, or as a
                 consequence of the imposition of governmental charges on a
                 lender as a result of the taking, or failure to take, of any
                 action by such lender, particularly in cases where (i) the
                 additional amount bears no reasonable relation to the damage
                 suffered by the lender or is otherwise held to be a penalty
                 (see, e.g., Lazzarechi Inv.  Co. v. San Francisco Federal
                 Savings and Loan Assoc., 22 Cal. App. 3d 303 (1971), and
                 Hellenbaum v. Lytton Savings & Loan Association, 274 Cal. App.
                 2d 456 (1969)), or (ii) such increases constitute penalties or
                 forfeitures or are otherwise contrary to public policy.

         G.      We express no opinion with respect to the legality, validity,
                 binding nature or enforceability of any provision of any Loan
                 Document to the effect that rights or remedies are cumulative
                 or are not exclusive, that the election of some particular
                 remedy or remedies does not preclude recourse to one or more
                 other remedies or that failure to exercise or delay in
                 exercising rights or remedies will not operate as a waiver of
                 any such right or remedy.

         H.      We express no opinion as to any provision of any Loan Document
                 requiring written amendments or waivers of such documents
                 insofar as it suggests that oral or other modifications,
                 amendments or waivers could not be effectively agreed upon by
                 the parties or that the doctrine of promissory estoppel might
                 not apply.

         I.      We have assumed that there are no agreements or understandings
                 between or among the Company, the Bank, or any third parties
                 which would expand, modify or otherwise affect the terms of
                 any Loan Document or the respective rights or obligations of
                 the





<PAGE>   124
Bank of America National Trust
  and Savings Association
As of February 19, 1997
Page 7



                 parties thereunder and that each of the Loan Documents
                 correctly and completely set forth the intent of all parties
                 thereto.

         J.      We have assumed that all parties to the Loan Documents have
                 filed all required franchise tax returns, if any, and paid all
                 required taxes, if any, under the California Revenue &
                 Taxation Code.

         K.      We have assumed that the Credit Agreement has been duly
                 authorized, executed and delivered by the Bank and that the
                 Bank has full power, authority and legal right to enter into
                 and perform the terms and conditions of the Credit Agreement
                 on its part to be performed and that the Credit Agreement
                 constitutes the legal, valid and binding obligation of the
                 Bank, enforceable against it in accordance with its terms.

         L.      We express no opinion as to the applicability or effect of
                 compliance or non-compliance by the Bank with any state,
                 federal or other laws applicable to the Bank or to the
                 transactions contemplated by the Loan Documents because of the
                 nature of its business, including its legal or regulatory
                 status.

         M.      We have assumed that the Bank is either (i) a "Bank" as
                 defined in and operating under that certain act known as the
                 "Bank Act" approved March 1, 1909, as amended, (ii) a bank
                 created and operating under and pursuant to the laws of the
                 State of California or of the United States or (iii) a foreign
                 bank complying with the criteria set forth in Section 1716 of
                 the California Financial Code, as amended, and is therefore
                 exempt from the provisions of Article XV of the California
                 Constitution and related statutes.

         N.      We express no opinion regarding compliance or non-compliance
                 (or the effect thereof) with applicable anti-fraud provisions
                 of federal or state securities laws, or with respect to the
                 "Blue Sky" laws of any state other than the State of

         O.      This opinion speaks only at and as of its date and is based
                 solely on the facts and circumstances existing as of such
                 date.  We express no opinion as to the effect on the Bank's
                 rights under the Loan Documents of any statute, rule,
                 regulation or other law which is enacted or becomes effective
                 after, or of any court decision which changes the law relevant
                 to such rights which is rendered after, the date of this
                 opinion or the conduct of the parties following the closing of
                 the contemplated transaction.  In addition, in rendering this
                 opinion, we assume no obligation to revise or supplement

                 this opinion should the present laws of the jurisdictions
                 mentioned herein be changed by legislative action, judicial
                 decision or otherwise.

         P.      We express no opinion as to any provision of any Loan Document
                 purporting to exculpate from liability an issuing bank which
                 makes payments against a presentment under any letter of
                 credit, to the extent the documents presented do not strictly
                 comply with the terms of such letter of credit.

         Q.      Without limitation of clause (i) of paragraph B above, we
                 express no opinion as to the effect of Sections 544 and 548 of
                 the Bankruptcy Code, Sections 3439 et. seq. of the California
                 Civil Code, or any other applicable federal or state,
                 statutory or common law relating to fraudulent transfers.

         R.      We express no opinion as to the effect of any provision of any
                 Loan Document purporting to relieve a secured party of any
                 duty it may have to preserve the value of collateral in its
                 possession (see California UCC Section 9207; see, also, e.g.
                 Citibank, N.A. v. Data Lease Financial Corporation 828 F.2d
                 686 (11th Cir. 1987)).

         S.      Our opinions set forth in paragraph 2 above is intended to
                 express our opinion that the execution, delivery and
                 performance by the Company of the respective Loan Documents to
                 which each is a party are neither prohibited by, nor subject
                 to the Company to a fine, penalty or similar sanction that
                 would be materially adverse to the Company under, any statute
                 or regulation of the State of California, the statutes
                 comprising the Delaware Corporation Laws or federal law that a
                 lawyer exercising customary professional diligence would
                 reasonably recognize as applicable to the Company or the Loan
                 Documents and the transactions contemplated thereby.

         This opinion is made with the knowledge and understanding that you
(but no other Person) may rely thereon in entering into the Credit Agreement
and is solely for your benefit.  This opinion may not be quoted to or relied
upon by any Person other than you without our prior written consent; provided,
that (i) this opinion may be disclosed to bank regulatory authorities having
jurisdiction over you requesting (or requiring) such disclosure and (ii) this
opinion may be disclosed to and relied upon by assignees of the Credit
Extensions if (a) such assignments are permitted under and made in accordance
with the Credit Agreement and (b) such assignees come within paragraph M above;
provided that in no event does this opinion extend to any issue or matter
related to any such assignment or arising from or out of any such assignment
(as distinct from the subject transaction).

         RE:     CREDIT AGREEMENT WITH BANK OF AMERICA
                 NATIONAL TRUST & SAVINGS ASSOCIATION

Ladies and Gentlemen:

         Reference is made to the Credit Agreement, dated as of the date hereof
(the "Credit Agreement") by and between the undersigned (the "Company"), and
Bank of America National Trust & Savings Association (the "Bank").  We have
requested you to render the legal opinion required by Section 5.01(f) of the
Credit Agreement (the "WSGR Opinion"; capitalized terms defined in the WSGR
Opinion, whether directly or indirectly by reference, and used without
definition herein to have the respective meanings herein assigned to such terms
in the WSGR Opinion).  With the understanding you will rely on the statements
of fact contained in this Certificate and Declaration (the "Certificate") in
delivering the WSGR Opinion, after due investigation, the Company hereby
certifies as follows:

         1.      Representations and Warranties.  The Company confirms to
Wilson Sonsini Goodrich & Rosati, P.C. ("WSGR") the accuracy and completeness
of the representations and warranties of the Company contained in Article VI of
the Credit Agreement, and acknowledges and agrees that WSGR is entitled to rely
thereon in connection with the WSGR Opinion.

         2.      Board Presentation.  The material terms and conditions of the
original credit facility refinanced by the Credit Agreement and the other Loan
Documents were fairly and accurately presented to the Board of Directors of the
Company and approved by the Board prior to their execution and delivery in
January 1994.  Prior to the approval of the minutes of the January, 1997
meeting of the Board, the Directors will have an opportunity to discuss and
review the terms of the Credit Agreement and the other Loan Documents,
particularly those material terms which have been modified from the prior
credit facility.

                 Duly Incorporated; Good Standing.  The Company has been duly
incorporated and is in good standing under the laws of its jurisdiction of
incorporation, with power and authority

(corporate and other) to own its properties and carry on its business as

into by and between PLANTRONICS, INC., a Delaware corporation (the "Company")

         A.  The Company and the Bank are parties to a Credit Agreement dated
as of February 19, 1997 (the "Credit Agreement") pursuant to which the Bank has

         B.  The Company and the Bank desire to amend the Credit Agreement to
correct an error therein, subject to the terms and conditions of this
Amendment.

         NOW, THEREFORE, for valuable consideration, the receipt and adequacy
of which are hereby acknowledged, the parties hereto hereby agree as follows:

         1.  Defined Terms.  Unless otherwise defined herein, capitalized terms
used herein shall have the meanings, if any, assigned to them in the Credit
Agreement.

         2.  Amendments to Credit Agreement.

                 (a)  Section 8.12 of the Credit Agreement is hereby amended
and restated in its entirety to read as follows:

                 8.12  Net Funded Debt to EBITDA Ratio.  The Company shall not
         permit as of the last day of any fiscal quarter the Net Funded Debt to
         EBITDA Ratio to be more than 3.00:1.00.

                 (b)   Schedule 2 to Exhibit C to the Credit Agreement (the

         3.  Representations and Warranties.  The Company hereby represents and
warrants to the Bank that the execution, delivery and performance by the

<PAGE>   144
         4.      Reservation of Rights.  The Company and the Bank acknowledge
and agree that the execution and delivery by the parties of this Amendment
shall not be deemed to create a course of dealing or otherwise obligate the
Bank or the Company to execute similar amendments under the same or similar
circumstances in the future.

         5.      Miscellaneous.

                 (a)  Except as herein expressly amended, all terms, covenants
and provisions of the Credit Agreement are and shall remain in full force and
effect and all references therein to such Credit Agreement shall henceforth
refer to the Credit Agreement as amended by this Amendment.  This Amendment
shall be deemed incorporated into, and a part of, the Credit Agreement.

                 (b)  This Amendment shall be binding upon and inure to the
benefit of the parties hereto and thereto and their respective successors and
assigns.  No third party beneficiaries are intended in connection with this
Amendment.

accordance with the law of the State of California.

                 (d)  This Amendment may be executed in any number of
counterparts, each of which shall be deemed an original, but all such
counterparts together shall constitute but one and the same instrument.

                 (e)  This Amendment, together with the Credit Agreement,
contains the entire and exclusive agreement of the parties hereto with
reference to the matters discussed herein and therein.  This Amendment
supersedes all prior drafts and communications with respect thereto.  This
Amendment may not be amended except in accordance with the provisions of
Section 10.01 of the Credit Agreement.

                 (f)  If any term or provision of this Amendment shall be
deemed prohibited by or invalid under any applicable law, such provision shall
be invalidated without affecting the remaining provisions of this Amendment or
the Credit Agreement, respectively.

Dear Shareholder:

FOCUS ON GROWTH In fiscal 1997 we grew sales 6.7% to $195.3 million while
earnings outpaced this, growing 16.5% to $29.7 million, our fifth consecutive
record year. The good news is that our major market segments are growing and
should provide a platform for continuing growth well into the future. We have
seen the continued expansion of call centers in the U.S., many of which are
upgrading to our newer products, accelerating international demand, and
increasing requirements from office professionals, the small office/home office
market segment, and the mobile professional market segment. These latter
emerging markets are potentially larger than our core call center business.

THE NEW MARKETS VALUE MOBILITY Therefore, we are focusing our growing R&D effort
on wireless products to serve these market segments. In June we announced the
AirSet(TM) Cordless Adapter - a wireless headset for the office market segment -
which we believe represents a major advancement in acoustics, convenience and
affordability and early market reaction is encouraging. During the past year we
also introduced our first headsets for mobile phones.

PERFORMANCE To grow a successful profitable business, we must deliver value to
our customers. In fiscal 97, a survey of our channel partners ranked Plantronics
#1 in 46 of 51 major business areas, 2nd in the other 5, and 1st overall. In
addition, we were honored by the decisions of Deutsche Telekom and Telstra, the
giant German and Australian telecommunication providers, both of whom selected
Plantronics as their main headset supplier for the first time.

Internal performance is improving as well with gross margin increasing from
52.5% to 53.6% and return on sales increasing from 13.9% to 15.2%. Productivity,
as measured by both revenue per person and operating income per person, also
improved. Based on higher operating income and a 10% improvement in accounts
receivable turnover, Plantronics generated $34.6 million of cash flow from
operations, of which $12.8 million was used to repurchase stock. In total, our
cash position increased by over $15 million to $42.3 million.

For shareholders, both absolute and relative performance are crucial metrics.
Since Plantronics' IPO in January of 1994, the stock price has increased at a
46.5% compound annual rate, exceeding our peer groups. We realize your focus is
the return we have to generate tomorrow and this is ours as well. To spread this
incentive throughout the team, we have implemented an incentive stock purchase
plan for all of our associates worldwide.

Internal growth is not our only avenue for expansion. We recently brought on
board a Senior Vice President of Corporate Development and a new CFO to help us
evaluate other avenues for growth and added capability to achieve our goal of
being a thriving global competitor in the next century. We turn to fiscal 1998
stronger than we were a year ago and are very appreciative of the continuing
support of our customers, distribution partners, suppliers, shareholders, and
associates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



NOTE 1 -- THE COMPANY:

Plantronics, Inc. (the Company), which introduced the first lightweight headset
in 1962, is the world's largest designer, manufacturer and marketer of
lightweight communications headsets. In addition, Plantronics manufactures and
markets specialty telephone products, such as amplified telephone handsets and
specialty telephones for hearing-impaired users and noise-canceling handsets for
use in high-noise environments.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

MANAGEMENT'S USE OF ESTIMATES AND ASSUMPTIONS

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of
contingent assets and liabilities at the date of financial statements and the
reported amounts of sales and expenses during the reporting period. Actual
results could differ from those estimates.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of Plantronics and
its subsidiary companies. Intercompany transactions and balances have been
eliminated in consolidation.

FISCAL YEAR

The Company's fiscal year end is the Saturday closest to March 31. For purposes
of presentation, the Company has indicated its accounting year ending on March
31 or the month-end for interim quarterly periods. Results of operations for
fiscal years 1997, 1996 and 1995 each included 52 weeks.

CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

The Company considers all highly liquid investments with a maturity of 90 days
or less at the date of purchase to be cash equivalents. Management determines
the appropriate classification of debt and equity securities at the time of
purchase, and reassesses the classification at each reporting date. At March 31,
1997, all of the Company's short-term investments, consisting primarily of fixed
maturity debt securities, have been classified as "held to maturity". Under this
classification, the investments are recorded at amortized cost. At March 31,
1997 the average maturity of the Company's short-term investments was
approximately seven days. The Company's cash and cash equivalents consist of the
following:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



DEPRECIATION AND AMORTIZATION

Depreciation and amortization of property, plant and equipment are principally
calculated using the straight-line method over the estimated useful lives of the
respective assets.

DEFERRED DEBT ISSUANCE COSTS

Debt issuance costs are assigned to the various debt instruments and amortized
over the shorter of: the terms of the respective debt agreements or an estimated
period the debt will be outstanding.

REVENUE RECOGNITION

Revenue is recognized when products are shipped. Provision is made for estimated
potential customer returns and warranty costs at the time of shipment.

CONCENTRATION OF CREDIT RISK

Financial instruments which potentially subject the Company to concentrations of
credit risk consist principally of cash equivalents and trade receivables. The
Company's cash investment policies limit investments to those that are
short-term and low risk. Concentrations of credit risk with respect to trade
receivables are generally limited due to the large number of customers
comprising the Company's customer base, and their dispersion across many
different geographic areas. The Company performs ongoing credit evaluations of
its customers' financial condition and, generally, requires no collateral from
its customers. The Company maintains an allowance for uncollectible accounts
receivable based upon expected collectibility of all accounts receivable.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying value of the Company's financial instruments, including cash, cash
equivalents, accounts receivable, accrued expenses and liabilities, approximate
fair value due to their short maturities. The fair value of long-term debt,
including the current portion, was estimated by management based on current
rates offered to the Company for debt of the same remaining maturities. The fair
value of the long-term debt was not materially different from the carrying value
of $65.1 million at March 31, 1997.

INCOME TAXES

The Company accounts for income taxes under the liability method, which
recognizes deferred tax assets and liabilities for the expected future tax
consequences of temporary differences between the tax basis of assets and
liabilities and their financial statement reported amounts.

FOREIGN OPERATIONS AND CURRENCY TRANSLATION

The Company has foreign assembly and manufacturing operations in Mexico, light
assembly, research and development and sales and marketing in the United
Kingdom, an international finance, customer service and logistics headquarters
in the Netherlands, and sales offices in Canada, Asia, Europe and South America.
For fiscal 1997, the functional currency of all foreign operations was the US
dollar. For fiscal 1996 and 1995, the functional currency of all foreign
operations was the US dollar, with the exception of the operation located in the
United Kingdom. Accordingly, gains or losses arising from the translation of
foreign currency statements and transactions, except for the operation in the
United Kingdom in fiscal 1996 and 1995, are included in determining consolidated
results of operations. Aggregate exchange gains for fiscal 1997, 1996 and 1995
were $0.4 million, $0.3 million and $0.1 million, respectively. Gains or losses
arising from the translation of the United Kingdom statements prior to fiscal
1997 were recorded as a separate component of stockholders' equity.

STOCK BASED COMPENSATION

Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation," ("FAS 123"), encourages, but does not require, companies to
record compensation cost for stock-based employee compensation plans based on
the fair value of options granted. The Company has elected to continue to
account for stock-based compensation using the intrinsic value method prescribed
in Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" and related interpretations, and to provide additional disclosures
with respect to the pro forma effects of adoption had the company recorded
compensation expense as provided in FAS 123, (see Note 10.)

NET INCOME PER COMMON SHARE

Net income per share is computed using the weighted average number of common and
dilutive common equivalent shares outstanding. Common equivalent shares consist
of stock options computed using the treasury stock method.

RECENT ACCOUNTING PRONOUNCEMENT (UNAUDITED)

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings per Share." The statement is
effective for the Company's fiscal year ending March 31, 1998. This statement
amends the calculation of earnings per share as prescribed by generally accepted
accounting principles. Under the new standard, primary earnings per share is
replaced by basic earnings per share and fully diluted earnings per share is
replaced by diluted earnings per share.

The following pro-forma information presents per share information as if the
Company had adopted the standard for the fiscal year, ended March 31, 1997 and
1996.

NOTE 4 -- DEBT:

Long-term debt, consisting of Senior Notes, was $65.1 million at the end of
fiscal 1997, 1996 and 1995. The Senior Notes are general unsecured obligations
of the Company with an original aggregate principal amount of $85.0 million that
bear interest, payable semiannually, at a rate of 10% per annum and will mature
on January 15, 2001. The Senior Notes are redeemable, at the Company's option,
in whole or in part, at any time on or after January 15, 1999. Redemption prior
to January 15, 2001 will be at a premium. During fiscal 1995, the Company
repurchased Senior Notes with face values of $19.9 million in principal for
$19.8 million, resulting in a gain of $0.1 million.

The Senior Note Indenture contains certain covenants that, among other things,
limit the ability of the Company and its subsidiaries to incur indebtedness, pay
dividends, issue preferred stock of subsidiaries, engage in transactions with
affiliates, create liens, engage in mergers and consolidations, or make certain
asset sales and investments. The Senior Note Indenture also provides that
holders of the Senior Notes have the right to require that the Company
repurchase their Senior Notes in the event of a "change in control" and contain
various customary events of default.

During fiscal 1995, the Company expanded its previous $20.0 million revolving
credit facility, including a $4.0 million letter of credit facility, with Bank
of America National Trust and Savings Association ("Bank of America") by $9.0
million to partially fund the repurchase of Senior Notes. The $9.0 million
expanded facility was terminated by the Company in fiscal 1996. The remaining
$20.0 million facility expired in fiscal 1997.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Through fiscal 1996, obligations of the Company under the remaining facility
were secured by liens on inventory and accounts receivable of the Company and
certain related assets.


During fiscal 1997, the Company entered into a new, one-year $20.0 million
revolving unsecured credit facility with Bank of America. The facility includes
a $10.0 million letter of credit subfacility. Combined borrowings and
commitments under both facilities cannot exceed $20.0 million. Principal
outstanding bears interest at the Company's choice of the Bank of America base
rate, the offshore rate or a CD rate plus a margin ranging from 0.000% to
1.375%, depending on the rate choice and performance level ratios. There were no
borrowings outstanding under the facility at March 31, 1997, however, at that
date $3.4 million, associated with inventory purchases and other matters, was
committed under the letter of credit subfacility. The new revolving credit
facility includes covenants relating to, among other things, the maintenance of
a maximum net funded debt ratio, a minimum tangible net worth ratio and a
maximum interest coverage ratio. The Company was in compliance with the terms of
the covenants as of March 31, 1997.

The new revolving credit facility also expressly restricts the ability of the
Company to incur additional indebtedness (including contingent liabilities and
guarantees), grant additional liens, redeem stock, dispose of and acquire
assets, incur lease obligations, and make investments, including loans, joint
ventures, and acquisitions of other businesses. The Company is permitted to pay
cash dividends on shares of its capital stock in an amount not to exceed 50% of
the Company's cumulative net income (net of cumulative losses) for the period
commencing February 19, 1997 through the date of declaration.


NOTE 5 -- TREASURY STOCK:

During fiscal 1997 the Company purchased 350,613 shares of its Common Stock in
the open market at a total cost of $12.8 million. The shares were repurchased
primarily to provide shares for the Company's employee stock plans. A total of
2,542 shares were reissued during fiscal 1997.

NOTE 7 -- EMPLOYEE BENEFIT PLANS:

Subject to eligibility requirements, substantially all domestic employees are
covered by quarterly cash and annual deferred profit sharing plans. Employees
also have the option of participating in a salary deferral plan qualified under
Section 401(k) of the Internal Revenue Service Code. The Quarterly Profit
Sharing Plan benefits are paid on the basis of profitability and the
relationship of each participating employee's base salary as a percent of all
participants' base salaries. The Annual Profit Sharing Plan benefits are based
on 10% of the Company's results of operations before interest and taxes,
adjusted for other items, minus quarterly profit sharing cash distributions and
administrative expenses, and are allocated to employees based on the
relationship of each participating employee's base salary as a percent of all
participants' base salaries. The Annual Profit Sharing Plan distributions
include a cash distribution and a tax deferred distribution made to individual
accounts of participants held in trust. The deferred portion is subject to a two
year vesting schedule. Total annual and quarterly profit sharing contributions
were $5.5 million, $5.4 million and $4.6 million for fiscal 1997, 1996 and 1995,
respectively.

stock splits, reverse stock splits, recapitalization or certain corporate
reorganizations) are reserved for issuance to employees and consultants of the
Company, as approved from time to time by the Compensation Committee of the
Board of Directors. The reserved shares include 490,000 shares which were
authorized by the Board of Directors and approved by the stockholders for
issuance in 1997. The 1993 Stock Plan, which has a term of ten years, provides
for incentive as well as nonqualified stock options to purchase shares of Common
Stock. The Board of Directors may terminate the 1993 Stock Plan at any time at
its discretion.


Incentive stock options may not be granted at less than 100 percent of the
estimated fair market value, as determined by the Board of Directors, of the
Company's Common Stock at the date of grant and the option term may not exceed
10 years. For holders of 10 percent or more of the total combined voting power
of all classes of the Company's stock, incentive stock options may not be
granted at less than 110 percent of the estimated fair market

value of the Common Stock at the date of grant and the option term may not
exceed five years. Nonqualified stock options may be granted at less than fair
market value. Options generally vest over 4 years.

In September 1993 the Compensation Committee of the Board of Directors approved
nonqualified options to certain executive officers to purchase 127,896 shares of
Common Stock at an exercise price of $5.47 per share that were granted upon the
completion of the Company's initial public offering. Compensation related to
these options of $0.9 million based on the $12.50 per share offering price is
being charged to expense over a four year-vesting period commencing January 1994
as the options were granted for future services. Options to purchase an
additional 144,626 shares were granted during fiscal 1994 to certain executive
officers at exercise prices ranging from $5.47 and $15.25 per share.
Compensation related to these options of $0.8 million is being charged to
expense over a four-year vesting period. As of March 31, 1997, the unamortized
portion of the total compensation expense, after considering canceled options,
amounted to $0.2 million.

DIRECTORS' STOCK OPTION PLAN

In September 1993, the Board of Directors adopted a Directors' Stock Option Plan
(the "Directors' Option Plan") and reserved 20,000 shares of Common Stock for
issuance to non-employee directors of the Company. An additional 10,000 shares
were authorized for issuance in 1997 under the Directors' Option Plan, pursuant
to Board of Directors' and stockholder approval. The Directors' Option Plan
provides that each non-employee director shall be granted an option to purchase
2,000 shares of Common Stock on the later of the effective date of the Company's
initial public offering or the date on which the person becomes a director.
Accordingly, each of the Company's three current outside directors was granted
an option to purchase 2,000 shares of Common Stock upon the effective date of
the offering. In addition, three additional persons who became directors of the
Company upon completion of this offering were granted options to purchase 2,000
shares of Common Stock. Thereafter, each non-employee director shall be granted
an option to purchase 500 shares of Common Stock each year. At the end of fiscal
1997, options for 21,000 shares of Common Stock were outstanding under the
Directors' Option Plan. All options were granted at fair market value and
accordingly, had no compensatory impact. Options vest generally over a four-year
period.

Stock option activity under the 1993 Stock Plan and the Directors' Stock Option
Plan are as follows:

EMPLOYEE STOCK PURCHASE PLAN

On April 23, 1996 the Board of Directors of the Company approved the 1996
Employee Stock Purchase Plan, (the "ESPP") which was approved by the
stockholders on August 6, 1996, to provide certain employees with an opportunity
to purchase Common Stock through payroll deductions. The plan is a qualified
plan under applicable IRS guidelines and highly compensated employees are
excluded from participation. Under the ESPP, the purchase price of the Common
Stock will equal 95% of the market price of the Common Stock immediately before
the beginning of the applicable participation period. Each participation period
is 6 months long. Once purchased the shares are restricted for 6 months. During
1997, 581 shares were issued under the plan. The fair value of the employee's
purchase rights was estimated using the Black-Scholes model with the following
assumptions for 1997; dividend yield of 0%, an expected life of 6 months,
expected volatility of 17%, and risk free interest rates of 5.5%. The
weighted-average fair value of these purchase rights granted in fiscal 1997 was
$2.27.


SENIOR EXECUTIVE STOCK OWNERSHIP PLAN

In November, 1996 the Board of Directors approved a Senior Executive Stock
Purchase Plan, effective January 1, 1997, to encourage ownership of the
company's Common Stock by senior executives. This is a voluntary plan in which
executives are encouraged to participate and achieve a target ownership over a 5
year period in annual increments of 20% or more. The target ownership is equal
to two times the Chief Executive Officer's base salary and one times the
individual Vice Presidents' base salary. To encourage participation, the
Company's Treasury Stock will be sold by the Company to executives under this
voluntary purchase program. The price will be equal to the greater of: 95% of
the price set by the Board of Directors on an annual basis or 85% of the fair
market value of the stock on the date of transaction. The various vehicles that
are available to executives to obtain ownership of the company's stock are as
follows: 401 (K) Plan contributions, personal IRA account purchases, Deferred
Compensation Plan contributions, outright purchase of stock or exercising and
holding vested stock options. The discounted price is not applicable to
exercising and holding of vested stock options.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS


ANNUAL RESULTS OF OPERATIONS

NET SALES. Net sales increased 6.7% to $195.3 million in fiscal 1997 from $183.0
million in fiscal 1996. Net sales for fiscal 1996 had increased 7.7% from $169.9
million in fiscal 1995. Over these periods, there were no significant price
increases. Domestic revenue growth occurred despite an anticipated decline in
total sales to Lucent Technologies (formerly a subsidiary of AT&T). Total sales
in fiscal 1997 to this customer were down $2.0 million from fiscal 1996 levels.
The fiscal 1997 decline reflected the customer's desire to lower its stocking
levels as well as to close certain retail outlets. International revenue grew
22% in fiscal 1997 as compared to fiscal 1996 resulting primarily from expansion
of sales in new geographic markets and investment in customer focused marketing
programs. The Company's net sales to customers outside the United States,
predominantly in Europe, were $59.6 million, $49.0 million and $41.7 million in
fiscal 1997, 1996 and 1995, respectively, and accounted for 30.5%, 26.8% and
24.5%, respectively, of net sales in those periods. Revenue levels in fiscal
1997 were not impacted in either direction by changes in prices or by shipping
levels of Walker Equipment (a division of the Company) specialty products.

GROSS PROFIT. The Company's gross profit increased over the past three years to
$104.7 million in fiscal 1997 from $96.1 million in fiscal 1996 and $85.7
million in fiscal 1995. Gross profit as a percent of net sales was 53.6% in
fiscal 1997, 52.5% in fiscal 1996 and 50.4% in fiscal 1995. The $19.0 million
improvement in gross profit over the three year period primarily reflects the
impact of additional revenues ($25.4 million) with the balance consisting of
benefits from improved manufacturing efficiencies and from material and
logistics cost reduction programs. In addition, the warranty provision as a
percent of revenue has declined since fiscal 1995.

OPERATING EXPENSES. Operating expenses for the Company were $54.4 million or
27.9% of net sales in fiscal 1997, $48.6 million or 26.5% of net sales in fiscal
1996 and $42.5 million or 25.0% of net sales in fiscal 1995. Research,
development and engineering expenses increased $0.8 million in fiscal 1997 as
compared to fiscal 1996 due to the creation of an engineering development team
in Europe. The Company believes it will be better able to develop products for
the European and other international markets with an R&D presence in the United
Kingdom. Sales, general and administrative expenses increased $5.1 million in
fiscal 1997 primarily due to additional staffing in sales and marketing
worldwide and increased spending on international marketing communication
programs.

INTEREST EXPENSE. Interest expense was $7.1 million in fiscal 1997, $7.1 million
in fiscal 1996 and $8.0 million in fiscal 1995. Included in interest expense in
fiscal 1997, fiscal 1996, and fiscal 1995 was $0.5 million , $0.5 million, and
$0.6 million, respectively, in non-cash deferred debt issuance costs related to
the Senior Notes and revolving credit facility. Unamortized deferred debt costs
related to the revolving credit facility and Senior Notes at March 31, 1997 were
$1.4 million which are being amortized over the remaining terms of the debt.


FOREIGN CURRENCY. The Company's cash flows are substantially US dollar
denominated. However, the Company is exposed to certain foreign currency
fluctuations, primarily in Europe and Mexico. The source of currency risk in
Europe is due to receivables denominated in local currency, although this has
been largely offset by payables denominated in local currency. This natural
hedging approach has substantially limited the Company's net exposure to the
effect of currency fluctuations and management believes additional hedging has
not been merited. As the Company's sales in Europe grow, this strategy will
require review and the Company may experience greater exposure to currency
fluctuations as a result of its increasing international activities. In the
fourth quarter of fiscal 1996, the company formed a wholly owned subsidiary
incorporated in the Netherlands. The establishment of Plantronics B.V. entailed,
among other things, a transfer of a substantial number of functions and the
associated positions and expenses from the United Kingdom to the Netherlands.
The Company now incurs local expenses in Dutch guilders and a smaller proportion
of expenses in pound sterling, while recording no revenue in Dutch guilders.

<PAGE>   28
                      MANAGEMENT'S DISCUSSION AND ANALYSIS


The Company's peso transaction exposure at its manufacturing subsidiary in
Tijuana, Mexico is limited mostly to payroll. The favorable effects to the
Company on the devaluation of the peso in the years reported was somewhat offset
by local currency pay raises to its employees in Mexico. Because of these
factors, management does not believe the devaluation has had a material effect
on the Company.

In fiscal 1997, the impact of foreign currency on operations was a favorable
$0.4 million compared to a favorable $0.3 million in fiscal 1996.

INCOME TAX EXPENSE. In fiscal 1997, fiscal 1996 and fiscal 1995 income tax
expense was $15.3 million, $16.3 million and $14.5 million, respectively,
representing an effective tax rate of 34%, 39% and 41%, respectively. As a
result of the incorporation of the Netherlands subsidiary, the Company's
effective tax rate was lower in fiscal 1997, compared to the rate in fiscal 1996
and fiscal 1995, and may continue to be reduced. The Netherlands subsidiary was
formed to be a strategic logistics center for international sales and the
headquarters for its international operations.

FACTORS AFFECTING FUTURE OPERATING RESULTS

The statements in the paragraphs captioned "Interest Expense" and "Income Tax
Expense" include forward looking statements which involve risk and
uncertainties. In addition, the Company may from time to time make oral forward
looking statements. The Company's actual results could differ materially from
those anticipated in these forward looking statements as a result of the
following factors and other factors identified in the Company's Securities and
Exchange Commission filings.

NEED TO SUCCESSFULLY DEVELOP NEW PRODUCTS AND MARKETS. The Company's net sales
to date have been derived principally from the sale of lightweight
communications headsets ("tops") and associated bases ("bottoms"). Historically,
a substantial portion of the Company's sales have been made through distributors
to call center users and its product development efforts have primarily been
directed toward incremental enhancements of existing products. In the future,
the Company intends to both enhance its existing products and to develop new
products that capitalize on its core technology and expand the Company's product
offerings to new user market segments. The success of new product introductions
is dependent on several factors, including proper new product selection, timely
completion and introduction of new product designs, quality of new products and
market acceptance. The Company has recently expanded its marketing efforts to
sell lightweight headsets to the business, home office, computer and mobile user
market segments. Although the Company has attempted to determine the specific
needs of these new market segments there can be no assurance that the market
niches identified will in fact materialize or that the Company's existing and
future products designed for these segments will gain substantial market
acceptance.

COMPETITION. As the Company develops new generations of products and enters new
market segments, including the developing business, home office, computer and
mobile user market segments, the Company anticipates that it may face additional
competition from companies which currently do not offer communications headsets.
Such companies may be larger, offer broader product lines and have substantially
greater financial and other resources than the Company. Such competition could
negatively affect pricing and gross margins. Although the Company has
historically competed very successfully in the call center user segment of the
market, there can be no assurance that it will be able to continue its
leadership position in that segment of the market or that the Company will be
able to compete successfully in new market segments.


DEMAND OF CHANGING TECHNOLOGIES. The technology of telephone headsets, both
"tops" and "bottoms," has traditionally evolved slowly. Products are currently
exhibiting life cycles of three to five years before introduction of the next
generation of products. Historically, new product offerings included stylistic
changes and quality improvements but have usually been based on similar
technology.

<PAGE>   29
                      MANAGEMENT'S DISCUSSION AND ANALYSIS



The Company believes that future changes in technology may come at a faster
pace, particularly in the telephone, cellular telephone and computer segments of
the business and home office user portions of the market.The Company's future
success will be dependent in part on its ability to develop products that
utilize new technologies and to introduce them successfully to the marketplace.
In addition, in order to avoid product obsolescence, the Company will have to
monitor technological changes in telephony, as well as users' demands for new
technologies. Failure by the Company to keep pace with future technological
changes could materially adversely affect the Company's revenues and operating
results.

UTILIZATION OF SINGLE SOURCE SUPPLIERS. The Company's manufacturing operations
primarily consist of assembly of components and subassemblies that Plantronics
manufactures or purchases from a variety of sources. Although most components
and subassemblies used in the Company's manufacturing operations are obtained,
or are reasonably available, from numerous sources, certain of its products and
components (including semicustom integrated circuits that are key components of
the Company's products) are currently obtained only from single suppliers. The
Company currently purchases such components on a purchase order basis and has no
present intention to enter into master purchase agreements with any of its
single source suppliers. The Company has to date experienced only minor
interruptions in the supply of these components, none of which has adversely
affected its operations. However, an interruption in supply from any of the
Company's single source suppliers could temporarily result in the Company's
inability to deliver products on a timely basis, which in turn could adversely
affect its operations.

IMPORTANCE OF PATENTS AND OTHER INTELLECTUAL PROPERTY RIGHTS. The Company's
success will depend in part on its ability to obtain patents and preserve other
intellectual property rights covering the design and operation of its products.
The Company currently holds certain patents and intends to continue to seek
patents on its inventions when appropriate. The process of seeking patent
protection can be lengthy and expensive, and there can be no assurance that
patents will issue from currently pending or future applications or that the
Company's existing patents or any new patents issued will be of sufficient scope
or strength or provide meaningful protection or any commercial advantage to the
Company. The Company may be subjected to, or may initiate, litigation or patent
office interference proceedings, which may require significant financial and
management resources. Any such claims or litigation, unless promptly and
favorably resolved, could have a material adverse effect on the Company's
operations.

RISK ASSOCIATED WITH FOREIGN OPERATIONS AND SALES. Approximately 30.5% of the
Company's net sales in fiscal 1997 were derived from sales to foreign customers.
In addition, the Company conducts approximately 93% of its headset assembly
operations in Mexico, and obtains components from various foreign suppliers.
Manufacturing and sales of the Company's products could be adversely affected by
political or economic conditions in the United States or abroad, particularly in
Mexico. Sales to foreign customers are also generally subject to such risks as
increased tariffs and the imposition of other trade barriers.

The Company transacts business internationally in multiple currencies. Declines
in the values of local currencies relative to the United States dollar in
countries in which the Company does business could adversely affect the Company
by resulting in less competitive pricing for the Company's products. The Company
does not currently engage in any hedging activities to mitigate exchange rate
risks and to date has not been adversely affected by fluctuating currencies. To
the extent that the Company is successful in increasing its sales to foreign
customers, or to the extent that the Company increases its transactions in
foreign currencies, the Company's results of operations could be adversely
affected by exchange rate fluctuations.

DEPENDENCE UPON SENIOR MANAGEMENT. The Company believes that it has benefited
substantially from the leadership of Robert S. Cecil, the Chairman of the Board,
President and Chief Executive Officer of the Company, and the other current
members of senior management, and that the loss of their services could have a
material adverse effect on the Company's business and future operations.
Although the Company has an employment agreement with Mr. Cecil, such agreement
permits him to voluntarily terminate his employment at any time. In addition,
although Mr. Cecil's agreement contains a five-year non-compete covenant which
takes effect upon termination of his employment, such covenants are generally
not enforceable under California law.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS



LIQUIDITY AND CAPITAL RESOURCES

The Company's principal source of liquidity in fiscal 1997 was $34.6 million of
cash generated from operating activities. In fiscal 1996, liquidity was provided
by $26.9 million from operating activities. Cash and cash equivalents increased
to $42.3 million at March 31, 1997 from $26.8 million at March 31, 1996.

The Company has a $20.0 million credit facility, including a $10.0 million
letter of credit subfacility, with a major bank. In the quarter ended March 31,
1997, the Company renegotiated the terms of its credit facility so that
borrowings are no longer secured and ongoing fees and costs are substantially
reduced. As of March 31, 1997, the Company had no cash borrowings under the
revolving credit facility and had $3.4 million outstanding under the letter of
credit subfacility.

OPERATING ACTIVITIES. In fiscal 1997 the $34.6 million in net cash generated
from operating activities primarily resulted from $29.7 million in net income.
Also contributing to the increase in net cash were decreases in accounts
receivable and income taxes of $1.6 million and $1.0 million, respectively, and
an increase in accounts payable of $1.2 million, partially offset by an increase
in inventories of $2.0 million, and a decrease in income taxes payable of $1.8
million.

INVESTING ACTIVITIES. Capital expenditures were $8.2 million in fiscal 1997,
$3.9 million in fiscal 1996 and $3.6 million in fiscal 1995. The increase in
fiscal 1997 from fiscal 1996 principally consisted of investment in a
significant upgrade to the Company's business information systems. The Company
expects to invest an additional $1.0 million to $2.0 million in the information
systems upgrade by the middle of fiscal 1998.

FINANCING ACTIVITIES. In fiscal 1997 the Company repurchased 350,613 shares of
its Common Stock for $12.9 million, received $1.8 million in proceeds from the
exercise of stock options, and realized $0.1 million from the sale of 2,542
shares of Treasury Stock. The Company's financing activities during fiscal 1996
were limited to the receipt of $0.8 million in stock option exercise proceeds.
During fiscal 1995, financing activities consisted principally of borrowings
under the revolving credit facility and the repurchases at a discount of the
Company's outstanding 10% Senior Notes due 2001 with face value of $19.9 million
in principal for $19.8 million in cash. Management believed the debt repurchase
at or below par to be an efficient use of cash resources. For fiscal 1997, 1996
and 1995, aggregate interest expense (including current interest payable in
cash, deferred interest payable in cash and amortization of debt issuance costs)
was $7.1 million, $7.1 million and $8.0 million, respectively.

The remaining balance of the Senior Notes that were issued during fiscal 1994 in
the principal amount of $65.1 million bear interest, payable semiannually, at a
rate of 10% per annum and mature on January 15, 2001. The Senior Notes are
redeemable, at the Company's option, in whole or in part, any time after January
15, 1999. The Senior Note Indenture contains certain covenants that, among other
things, limit the ability of the Company and its subsidiaries to incur
indebtedness, pay dividends, issue preferred stock of subsidiaries, engage in
transactions with affiliates, create liens, engage in mergers and
consolidations, make certain asset sales or make certain investments. The Senior
Note Indenture also provides that holders of the Senior Notes have the right to
require the Company to repurchase their Senior Notes in the event of a "change
in control" and certain various customary events of default.

The Company believes that its current cash balance and cash to be provided by
operations, together with available borrowing capacity under the revolving
credit facility, will be sufficient to make required interest payments under the
Senior Notes and to fund operations at least through the next 12 months. Subject
to the terms and conditions of the 10% Senior Note Indenture and the Company's
revolving credit facility, the Company may use cash for such purposes as
repurchasing Senior Notes, repurchasing the Company's Common Stock or acquiring
complementary businesses, products or technologies.
