Ladies and Gentlemen:

       Plantronics, Inc., a Delaware corporation (the "Company"), and Citicorp
Venture Capital, Ltd. (the "Selling Stockholder"), confirm their respective
agreements with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") and each of the other Underwriters named in
Schedule A hereto (collectively, the "Underwriters", which term shall also
include any underwriter substituted as hereinafter provided in Section 10
hereof), with respect to (i) the sale by the Selling Stockholder and the
purchase by the Underwriters, acting severally and not jointly, of the
respective numbers of shares of Common Stock, par value $.01 per share, of the
Company ("Common Stock") set forth in Schedules A and B hereto and (ii) the
grant by the Selling Stockholder to the Underwriters, acting severally and not
jointly, of the option described in Section 2(b) hereof to purchase all or any
part of 150,000 additional shares of Common Stock to cover over-allotments, if
any. The aforesaid 1,000,000 shares of Common Stock (the "Initial Securities")
to be purchased by the Underwriters and all or any part of the 150,000 shares of
Common Stock subject to the option described in Section 2(b) hereof (the "Option
Securities") are hereinafter called, collectively, the "Securities."

       The Company and the Selling Stockholder understand that the Underwriters
propose to make a public offering of the Securities as soon as the Underwriters
deem advisable after this Agreement has been executed and delivered.



<PAGE>   4

       The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-37876) covering the
registration of the Securities under the Securities Act of 1933, as amended (the
"1933 Act"), including the related preliminary prospectus or prospectuses.
Promptly after execution and delivery of this Agreement, the Company will
prepare and file a prospectus in accordance with the provisions of Rule 430A
("Rule 430A") of the rules and regulations of the Commission under the 1933 Act
(the "1933 Act Regulations") and paragraph (b) of Rule 424 ("Rule 424(b)") of
the 1933 Act Regulations. The information included in such prospectus that was
omitted from such registration statement at the time it became effective but
that is deemed to be part of such registration statement at the time it became
effective pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A
Information". Each prospectus used before such registration statement became
effective, and any prospectus that omitted the Rule 430A Information that was
used after such effectiveness and prior to the execution and delivery of this
Agreement, is herein called a "preliminary prospectus." Such registration
statement, including the exhibits thereto, schedules thereto, if any, and the
documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the 1933 Act, at the time it became effective and including the Rule 430A
Information is herein called the "Registration Statement." Any registration
statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein
referred to as the "Rule 462(b) Registration Statement," and after such filing
the term "Registration Statement" shall include the Rule 462(b) Registration
Statement. The final prospectus, including the documents incorporated by
reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, in the
form first furnished to the Underwriters for use in connection with the offering
of the Securities is herein called the "Prospectus." For purposes of this
Agreement, all references to the Registration Statement, any preliminary
prospectus, the Prospectus or any amendment or supplement to any of the
foregoing shall be deemed to include the copy filed with the Commission pursuant
to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

       All references in this Agreement to financial statements and schedules
and other information which is "contained," "included" or "stated" in the
Registration Statement, any preliminary prospectus or the Prospectus (or other
references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which is incorporated
by reference in the Registration Statement, any preliminary prospectus or the
Prospectus, as the case may be; and all references in this Agreement to
amendments or supplements to the Registration Statement, any preliminary
prospectus or the Prospectus shall be deemed to mean and include the filing of
any document under the Securities Exchange Act of 1934 (the "1934 Act") which is
incorporated by reference in the Registration Statement, such preliminary
prospectus or the Prospectus, as the case may be.

       Section 1. Representations and Warranties.

       (a) Representations and Warranties by the Company. The Company represents
and warrants to each Underwriter as of the date hereof, as of the Closing Time
referred to in Section 2(c) hereof, and as of each Date of Delivery (if any)
referred to in Section 2(b) hereof, as follows:

              (i) Compliance with Registration Requirements. The Company meets
       the requirements for use of Form S-3 under the 1933 Act. Each of the
       Registration Statement and any Rule 462(b) Registration Statement has
       become effective under the 1933 Act and



                                        2
<PAGE>   5

       no stop order suspending the effectiveness of the Registration Statement
       or any Rule 462(b) Registration Statement has been issued under the 1933
       Act and no proceedings for that purpose have been instituted or are
       pending or, to the knowledge of the Company, are contemplated by the
       Commission, and any request on the part of the Commission for additional
       information has been complied with.

       At the respective times the Registration Statement, any Rule 462(b)
Registration Statement and any post-effective amendments thereto became
effective and at the Closing Time (and, if any Option Securities are purchased,
at the Date of Delivery), the Registration Statement, the Rule 462(b)
Registration Statement and any amendments and supplements thereto complied and
will comply in all material respects with the requirements of the 1933 Act and
the 1933 Act Regulations and did not and will not contain an untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein not misleading. Neither the
Prospectus nor any amendments or supplements thereto, at the time the Prospectus
or any such amendment or supplement was issued and at the Closing Time (and, if
any Option Securities are purchased, at the Date of Delivery), included or will
include an untrue statement of a material fact or omitted or will omit to state
a material fact necessary in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading. The
representations and warranties in this subsection shall not apply to statements
in or omissions from the Registration Statement or Prospectus made in reliance
upon and in conformity with information furnished to the Company in writing by
any Underwriter through Merrill Lynch expressly for use in the Registration
Statement or Prospectus.

       Each preliminary prospectus and the prospectus filed as part of the
Registration Statement as originally filed or as part of any amendment thereto,
or filed pursuant to Rule 424 under the 1933 Act, complied when so filed in all
material respects with the 1933 Act Regulations and each preliminary prospectus
and the Prospectus delivered to the Underwriters for use in connection with this
offering was identical in all material respects to the electronically
transmitted copies thereof filed with the Commission pursuant to EDGAR, except
to the extent permitted by Regulation S-T.

              (ii) Incorporated Documents. The documents incorporated or deemed
       to be incorporated by reference in the Registration Statement and the
       Prospectus, when they became effective or at the time they were or
       hereafter are filed with the Commission, complied and will comply in all
       material respects with the requirements of the 1933 Act and the 1933 Act
       Regulations or the 1934 Act and the rules and regulations of the
       Commission thereunder (the "1934 Act Regulations"), as applicable, and,
       when read together with the other information in the Prospectus, at the
       time the Registration Statement became effective, at the time the
       Prospectus was issued and at the Closing Time (and, if any Option
       Securities are purchased, at the Date of Delivery), did not and will not
       contain an untrue statement of a material fact or omit to state a
       material fact required to be stated therein or necessary to make the
       statements therein not misleading.

              (iii) Independent Accountants. The accountants who certified the
       financial statements and supporting schedules included in the
       Registration Statement are independent public accountants as required by
       the 1933 Act and the 1933 Act Regulations.



                                        3
<PAGE>   6

              (iv) Financial Statements. The financial statements included in
       the Registration Statement and the Prospectus, together with the related
       schedules and notes, present fairly the financial position of the Company
       and its consolidated subsidiaries at the dates indicated and the
       statements of operations, stockholders' equity and cash flows of the
       Company and its consolidated subsidiaries for the periods specified; said
       financial statements have been prepared in conformity with generally
       accepted accounting principles ("GAAP") applied on a consistent basis
       throughout the periods involved. The supporting schedules, if any,
       included in the Registration Statement present fairly in accordance with
       GAAP the information required to be stated therein. The selected
       financial data and the summary financial information included in the
       Prospectus present fairly the information shown therein and have been
       compiled on a basis consistent with that of the audited financial
       statements included in the Registration Statement.

              (v) No Material Adverse Change in Business. Since the respective
       dates as of which information is given in the Registration Statement and
       the Prospectus, except as otherwise stated therein, (A) there has been no
       material adverse change in the condition, financial or otherwise, or in
       the earnings or business affairs or business prospects of the Company and
       its subsidiaries considered as one enterprise, whether or not arising in
       the ordinary course of business (a "Material Adverse Effect"), (B) there
       have been no transactions entered into by the Company or any of its
       subsidiaries, other than those in the ordinary course of business, which
       are material with respect to the Company and its subsidiaries considered
       as one enterprise, and (C) there has been no dividend or distribution of
       any kind declared, paid or made by the Company on any class of its
       capital stock, except for repurchases by the Company of its Common Stock
       in the open market.

              (vi) Good Standing of the Company. The Company has been duly
       organized and is validly existing as a corporation in good standing under
       the laws of the State of Delaware and has corporate power and authority
       to own, lease and operate its properties and to conduct its business as
       described in the Prospectus and to enter into and perform its obligations
       under this Agreement; and the Company is duly qualified as a foreign
       corporation to transact business and is in good standing in each other
       jurisdiction in which such qualification is required, whether by reason
       of the ownership or leasing of property or the conduct of business,
       except where the failure so to qualify or to be in good standing would
       not result in a Material Adverse Effect.

              (vii) Good Standing of Subsidiaries. Each "significant subsidiary"
       of the Company (as such term is defined in Rule 1-02 of Regulation S-X)
       (each a "Subsidiary" and, collectively, the "Subsidiaries") has been duly
       organized and is validly existing as a corporation in good standing under
       the laws of the jurisdiction of its incorporation, has corporate power
       and authority to own, lease and operate its properties and to conduct its
       business as described in the Prospectus and is duly qualified as a
       foreign corporation to transact business and is in good standing in each
       jurisdiction in which such qualification is required, whether by reason
       of the ownership or leasing of property or the conduct of business,
       except where the failure so to qualify or to be in good standing would
       not result in a Material Adverse Effect; except as otherwise disclosed in
       the Registration Statement, all of the issued and outstanding capital
       stock of each such Subsidiary has been duly authorized and validly
       issued, is fully paid and non-assessable and is owned by the



                                        4
<PAGE>   7

       Company (other than directors' qualifying shares), directly or through
       subsidiaries, free and clear of any security interest, mortgage, pledge,
       lien, encumbrance, claim or equity; none of the outstanding shares of
       capital stock of any Subsidiary was issued in violation of the preemptive
       or similar rights of any securityholder of such Subsidiary. The only
       subsidiaries of the Company are (a) the Subsidiaries listed on Schedule D
       hereto and (b) certain other subsidiaries which, considered in the
       aggregate as a single Subsidiary, do not constitute a "significant
       subsidiary" as defined in Rule 1-02 of Regulation S-X.

              (viii) Capitalization. The authorized, issued and outstanding
       capital stock of the Company is as set forth in the Prospectus under the
       caption "Capitalization" (except for subsequent issuances, if any,
       pursuant to reservations, agreements or employee or director stock or
       benefit plans referred to in the Prospectus or pursuant to the exercise
       of convertible securities or options referred to in the Prospectus, or
       subsequent repurchases of Common Stock by the Company in the open
       market). The shares of issued and outstanding capital stock, including
       the Securities to be purchased by the Underwriters from the Selling
       Stockholder, are duly authorized and validly issued, fully paid and
       non-assessable. None of the outstanding shares of capital stock,
       including the Securities to be purchased by the Underwriters from the
       Selling Stockholder, was issued in violation of the preemptive or other
       similar rights of any securityholder of the Company.

              (ix) Authorization of Agreement. This Agreement has been duly
       authorized, executed and delivered by the Company.

              (x) Authorization and Description of Securities. The Common Stock
       conforms to all statements relating thereto contained in the Prospectus
       and such description conforms to the rights set forth in the instruments
       defining the same; no holder of the Securities will be subject to
       personal liability by reason of being such a holder; and the issuance of
       the Securities is not subject to the preemptive or other similar rights
       of any securityholder of the Company.

              (xi) Absence of Defaults and Conflicts. Neither the Company nor
       any of its subsidiaries is in violation of its charter or by-laws or in
       default in the performance or observance of any obligation, agreement,
       covenant or condition contained in any contract, indenture, mortgage,
       deed of trust, loan or credit agreement, note, lease or other agreement
       or instrument to which the Company or any of its subsidiaries is a party
       or by which it or any of them may be bound, or to which any of the
       property or assets of the Company or any subsidiary is subject
       (collectively, "Agreements and Instruments") except for such defaults or
       violations of the by-laws of the Subsidiaries that would not result in a
       Material Adverse Effect; and the execution, delivery and performance of
       this Agreement and the consummation of the transactions contemplated
       herein and in the Registration Statement and compliance by the Company
       with its obligations hereunder have been duly authorized by all necessary
       corporate action and do not and will not, whether with or without the
       giving of notice or passage of time or both, conflict with or constitute
       a breach of, or default or Repayment Event (as defined below) under, or
       result in the creation or imposition of any lien, charge or encumbrance
       upon any property or assets of the Company or any subsidiary pursuant to,
       the Agreements and Instruments (except for such conflicts, breaches or
       defaults or liens, charges or encumbrances that



                                        5
<PAGE>   8

       would not result in a Material Adverse Effect), nor will such action
       result in any violation of the provisions of the charter or by-laws of
       the Company or any subsidiary or, except for violations that would not
       result in a Material Adverse Effect, any applicable law, statute, rule,
       regulation, judgment, order, writ or decree of any government, government
       instrumentality or court, domestic or foreign, having jurisdiction over
       the Company or any subsidiary or any of their assets, properties or
       operations. As used herein, a "Repayment Event" means any event or
       condition which gives the holder of any note, debenture or other evidence
       of indebtedness (or any person acting on such holder's behalf) the right
       to require the repurchase, redemption or repayment of all or a portion of
       such indebtedness by the Company or any subsidiary.

              (xii) Absence of Labor Dispute. No labor dispute with the
       employees of the Company or any subsidiary exists or, to the knowledge of
       the Company, is imminent, and the Company is not aware of any existing or
       imminent labor disturbance by the employees of any of its or any
       subsidiary's principal suppliers, manufacturers, customers or
       contractors, which, in either case, may reasonably be expected to result
       in a Material Adverse Effect.

              (xiii) Absence of Proceedings. There is no action, suit,
       proceeding, inquiry or investigation before or brought by any court or
       governmental agency or body, domestic or foreign, now pending, or, to the
       knowledge of the Company, threatened, against or affecting the Company or
       any subsidiary, which is required to be disclosed in the Registration
       Statement (other than as disclosed therein), or which might reasonably be
       expected to result in a Material Adverse Effect, or which might
       reasonably be expected to materially and adversely affect the properties
       or assets thereof or the consummation of the transactions contemplated in
       this Agreement or the performance by the Company of its obligations
       hereunder; the aggregate of all pending legal or governmental proceedings
       to which the Company or any subsidiary is a party or of which any of
       their respective property or assets is the subject which are not
       described in the Registration Statement, including ordinary routine
       litigation incidental to the business, could not reasonably be expected
       to result in a Material Adverse Effect.

              (xiv) Accuracy of Exhibits. There are no contracts or documents
       which are required to be described in the Registration Statement, the
       Prospectus or the documents incorporated by reference therein or to be
       filed as exhibits thereto which have not been so described and filed as
       required.

              (xv) Possession of Intellectual Property. The Company and its
       subsidiaries own or possess, or can acquire on reasonable terms, adequate
       patents, patent rights, licenses, inventions, copyrights, know-how
       (including trade secrets and other unpatented and/or unpatentable
       proprietary or confidential information, systems or procedures),
       trademarks, service marks, trade names or other intellectual property
       (collectively, "Intellectual Property") necessary to carry on the
       business now operated by them in all material respects, and neither the
       Company nor any of its subsidiaries has received any notice or is
       otherwise aware of any infringement of or conflict with asserted rights
       of others with respect to any Intellectual Property or of any facts or
       circumstances which would render any Intellectual Property invalid or
       inadequate to protect the interest of the



                                        6
<PAGE>   9

       Company or any of its subsidiaries therein, and which infringement or
       conflict (if the subject of any unfavorable decision, ruling or finding)
       or invalidity or inadequacy, singly or in the aggregate, would result in
       a Material Adverse Effect.

              (xvi) Absence of Further Requirements. No filing with, or
       authorization, approval, consent, license, order, registration,
       qualification or decree of, any court or governmental authority or agency
       is necessary or required for the performance by the Company of its
       obligations hereunder, in connection with the offering or sale of the
       Securities hereunder or the consummation of the transactions contemplated
       by this Agreement, except such as have been already obtained or as may be
       required under the 1933 Act or the 1933 Act Regulations or state
       securities laws.

              (xvii) Possession of Licenses and Permits. The Company and its
       subsidiaries possess such permits, licenses, approvals, consents and
       other authorizations (collectively, "Governmental Licenses") issued by
       the appropriate federal, state, local or foreign regulatory agencies or
       bodies necessary to conduct the business now operated by them except
       where the failure to possess such Governmental Licenses would not, singly
       or in the aggregate, have a Material Adverse Effect; the Company and its
       subsidiaries are in compliance with the terms and conditions of all such
       Governmental Licenses, except where the failure so to comply would not,
       singly or in the aggregate, have a Material Adverse Effect; all of the
       Governmental Licenses are valid and in full force and effect, except when
       the invalidity of such Governmental Licenses or the failure of such
       Governmental Licenses to be in full force and effect would not have a
       Material Adverse Effect; and neither the Company nor any of its
       subsidiaries has received any notice of proceedings relating to the
       revocation or modification of any such Governmental Licenses which,

       (b)   Representations and Warranties by the Selling Stockholder.
The Selling Stockholder represents and warrants to each Underwriter as of the
date hereof, as of the Closing Time, and as of each Date of Delivery, and agrees
with each Underwriter, as follows:

              (i) Accurate Disclosure. The Selling Stockholder has reviewed and
       is familiar with the Registration Statement and the Prospectus and none
       of the information provided in writing by the Selling Stockholder for use
       in the Prospectus or any amendments or supplements thereto that is
       contained in the Prospectus or any amendments or supplements thereto
       includes any untrue statement of a material fact or omits to state a
       material fact necessary in order to make the statements therein, in light
       of the circumstances under which they were made, not misleading. The
       Selling Stockholder is not prompted to sell the Securities by any
       information concerning the Company or any subsidiary of the Company which
       is not set forth in the Prospectus.

              (ii) Authorization of Agreements. The Selling Stockholder has the
       full right, power and authority to enter into this Agreement and a Power
       of Attorney and Custody Agreement (the "Power of Attorney and Custody
       Agreement") and to sell, transfer and deliver the Securities to be sold
       by the Selling Stockholder hereunder. The execution and delivery of this
       Agreement and the Power of Attorney and Custody Agreement and the sale
       and delivery of the Securities by the Selling Stockholder and the
       consummation of



                                        8
<PAGE>   11

       the transactions contemplated herein and compliance by the Selling
       Stockholder with its obligations hereunder have been duly authorized by
       the Selling Stockholder and do not and will not, whether with or without
       the giving of notice or passage of time or both, conflict with or
       constitute a breach of, or default under, or result in the creation or
       imposition of any tax, lien, charge or encumbrance upon the Securities or
       any property or assets of the Selling Stockholder pursuant to any
       contract, indenture, mortgage, deed of trust, loan or credit agreement,
       note, license, lease or other agreement or instrument to which the
       Selling Stockholder is a party or by which the Selling Stockholder may be
       bound, or to which any of the property or assets of the Selling
       Stockholder is subject, nor will such action result in any violation of
       the provisions of the charter or by-laws or other organizational
       instrument of the Selling Stockholder, if applicable, or any applicable
       treaty, law, statute, rule, regulation, judgment, order, writ or decree
       of any government, government instrumentality or court, domestic or
       foreign, having jurisdiction over the Selling Stockholder or any of its
       properties.

              (iii) Good and Marketable Title. The Selling Stockholder has and
       will at the Closing Time and, if any Option Securities are purchased, on
       the Date of Delivery have good and marketable title to the Securities,
       free and clear of any security interest, mortgage, pledge, lien, charge,
       claim, equity or encumbrance of any kind, other than pursuant to this
       Agreement. Upon delivery of the Securities and payment of the purchase
       price therefor as herein contemplated, assuming each such Underwriter has
       no notice of any adverse claim, each of the Underwriters will receive
       good and marketable title to the Securities purchased by it from the
       Selling Stockholder, free and clear of any security interest, mortgage,
       pledge, lien, charge, claim, equity or encumbrance of any kind.

              (iv) Due Execution of Power of Attorney and Custody Agreement. The
       Selling Stockholder has duly executed and delivered, in the form
       heretofore furnished to the Underwriters, the Power of Attorney and
       Custody Agreement with S. Kenneth Kannappan and Barbara V. Scherer, or
       any of them, as attorney(s)-in-fact (the "Attorney(s)-in-Fact") and
       BankBoston, as custodian (the "Custodian"); the Custodian is authorized
       to deliver the Securities to be sold by the Selling Stockholder hereunder
       and to accept payment therefor; and each Attorney-in-Fact is authorized
       to execute and deliver this Agreement and the certificate referred to in
       Section 5(f) or that may be required pursuant to Sections 5(l) and 5(m)
       on behalf of the Selling Stockholder, to sell, assign and transfer to the
       Underwriters the Securities to be sold by the Selling Stockholder
       hereunder, to determine the purchase price to be paid by the Underwriters
       to the Selling Stockholder, as provided in Section 2(a) hereof, to
       authorize the delivery of the Securities to be sold by the Selling
       Stockholder hereunder, to accept payment therefor, and otherwise to act
       on behalf of the Selling Stockholder in connection with this Agreement.

              (v) Absence of Manipulation. The Selling Stockholder has not
       taken, and will not take, directly or indirectly, any action which is
       designed to or which has constituted or which might reasonably be
       expected to cause or result in stabilization or manipulation of the price
       of any security of the Company to facilitate the sale or resale of the
       Securities.

<PAGE>   12

              (vi) Absence of Further Requirements. To the best knowledge of the
       Selling Stockholder, no filing with, or consent, approval, authorization,
       order, registration, qualification or decree of, any court or
       governmental authority or agency, domestic or foreign, is necessary or
       required for the performance by the Selling Stockholder of its
       obligations hereunder or in the Power of Attorney and Custody Agreement,
       or in connection with the sale and delivery of the Securities hereunder
       or the consummation of the transactions contemplated by this Agreement,
       except such as may have previously been made or obtained or as may be
       required under the 1933 Act or the 1933 Act Regulations or state
       securities laws.

              (vii) Restriction on Sale of Securities. During a period of 90
       days from the date of the this Agreement, the Selling Stockholder will
       not, without the prior written consent of Merrill Lynch, (i) offer,
       pledge, sell, contract to sell, sell any option or contract to purchase,
       purchase any option or contract to sell, grant any option, right or
       warrant to purchase or otherwise transfer or dispose of, directly or
       indirectly, any share of Common Stock or any securities convertible into
       or exercisable or exchangeable for Common Stock or file any registration
       statement under the 1933 Act with respect to any of the foregoing or (ii)
       enter into any swap or any other agreement or any transaction that
       transfers, in whole or in part, directly or indirectly, the economic
       consequence of ownership of the Common Stock, whether any such swap or
       transaction described in clause (i) or (ii) above is to be settled by
       delivery of Common Stock or such other securities, in cash or otherwise.
       The foregoing sentence shall not apply to the Securities to be sold
       hereunder.

              (viii) Certificates Suitable for Transfer. Certificates for all of
       the Securities to be sold by the Selling Stockholder pursuant to this
       Agreement, in suitable form for transfer by delivery or accompanied by
       duly executed instruments of transfer or assignment in blank with
       signatures guaranteed, have been placed in custody with the Custodian
       with irrevocable conditional instructions to deliver such Securities to
       the Underwriters pursuant to this Agreement.

              (ix) No Association with NASD. Except with respect to the
       affiliation between Salomon Smith Barney Inc. and the Selling
       Stockholder, neither the Selling Stockholder nor any of its affiliates
       directly, or indirectly through one or more intermediaries, controls, or
       is controlled by, or is under common control with, or has any other
       association with (within the meaning of Article I (e)(e) of the By-laws
       of the National Association of Securities Dealers, Inc. (the "NASD")),
       any member firm of the NASD.

       (c) Officer's Certificates. Any certificate signed by any officer of the
Company or any of its subsidiaries delivered to the Underwriters or to counsel
for the Underwriters shall be deemed a representation and warranty by the
Company to each Underwriter as to the matters covered thereby; and any
certificate signed by or on behalf of the Selling Stockholder as such and
delivered to the Underwriters or to counsel for the Underwriters pursuant to the
terms of this Agreement shall be deemed a representation and warranty by the
Selling Stockholder to the Underwriters as to the matters covered thereby.

       Section 2. Sale and Delivery to Underwriters; Closing.

       (a)     Initial Securities. On the basis of the representations and
warranties herein contained and subject to the terms and conditions herein set
forth, the Selling Stockholder agrees to sell to each Underwriter, severally and
not jointly, and each Underwriter, severally and not jointly, agrees to purchase
from the Selling Stockholder, at the price per share set forth in Schedule C,
the number of Initial Securities set forth in Schedule A opposite the name of
such Underwriter, plus any additional number of Initial Securities which such
Underwriter may become obligated to purchase pursuant to the provisions of
Section 10 hereof.

       (b)     Option Securities. In addition, on the basis of the
representations and warranties herein contained and subject to the terms and
conditions herein set forth, the Selling Stockholder hereby grants an option to
the Underwriters, severally and not jointly, to purchase up to an additional
150,000 shares of Common Stock, as set forth in Schedule B, at the price per
share set forth in Schedule C, less an amount per share equal to any dividends
or distributions declared by the Company and payable on the Initial Securities
but not payable on the Option Securities. The option hereby granted will expire
30 days after the date hereof and may be exercised in whole or in part from time
to time only for the purpose of covering over-allotments which may be made in
connection with the offering and distribution of the Initial Securities upon
notice by the Underwriters to the Selling Stockholder setting forth the number
of Option Securities as to which the several Underwriters are then exercising
the option and the time and date of payment and delivery for such Option
Securities. Any such time and date of delivery (a "Date of Delivery") shall be
determined by the Underwriters, but shall not be earlier than three full
business days nor later than seven full business days after the exercise of said
option, nor in any event prior to the Closing Time, as hereinafter defined. If
the option is exercised as to all or any portion of the Option Securities, each
of the Underwriters, acting severally and not jointly, will purchase from the
Selling Stockholder on a pro rata basis, as necessary, that proportion of the
total number of Option Securities then being purchased which the number of
Initial Securities set forth in Schedule A opposite the name of such Underwriter
bears to the total number of Initial Securities, subject in each case to such
adjustments as the Underwriters in their discretion shall make to eliminate any
sales or purchases of fractional shares.

       (c)     Payment. Payment of the purchase price for, and delivery of
certificates for, the Initial Securities shall be made at the offices of Wilson
Sonsini Goodrich & Rosati, 650 Page Mill Road, Palo Alto, California 94304, or
at such other place as shall be agreed upon by the Underwriters and the Company
and the Selling Stockholder, at 7:00 A.M. (California time) on the third
(fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day)
business day after the date hereof (unless postponed in accordance with the
provisions of Section 10), or such other time not later than ten business days
after such date as shall be agreed upon by the Underwriters, the Company and the
Selling Stockholder (such time and date of payment and delivery being herein
called "Closing Time").

       In addition, in the event that any or all of the Option Securities are
purchased by the Underwriters, payment of the purchase price for, and delivery
of certificates for, such Option Securities shall be made at the above-mentioned
offices, or at such other place as shall be agreed upon by the Underwriters, the
Company and the Selling Stockholder, on each Date of Delivery as specified in
the notice from the Underwriters to the Company and the Selling Stockholder.



                                       11
<PAGE>   14

       Payment shall be made to the Selling Stockholder by wire transfer of
immediately available funds to a bank account designated by the Custodian
pursuant to the Selling Stockholder's Power of Attorney and Custody Agreement
against delivery to the Underwriters of certificates for the Securities to be
purchased by them. It is understood that each Underwriter has authorized Merrill
Lynch, for its account, to accept delivery of, receipt for, and make payment of
the purchase price for, the Initial Securities and the Option Securities, if
any, which it has agreed to purchase. Merrill Lynch, individually and not as
representative of the Underwriters, may (but shall not be obligated to) make
payment of the purchase price for the Initial Securities or the Option
Securities, if any, to be purchased by any Underwriter whose funds have not been
received by the Closing Time or the relevant Date of Delivery, as the case may
be, but such payment shall not relieve such Underwriter from its obligations
hereunder.

       (d) Denominations; Registration. Certificates for the Initial Securities
and the Option Securities, if any, shall be in such denominations and registered
in such names as the Underwriters may request in writing at least one full
business day before the Closing Time or the relevant Date of Delivery, as the
case may be. The certificates for the Initial Securities and the Option
Securities, if any, will be made available for examination and packaging by the
Underwriters in The City of New York not later than 10:00 A.M. (Eastern time) on
the business day prior to the Closing Time or the relevant Date of Delivery, as
the case may be.

       Section 3. Covenants of the Company. The Company covenants with each
Underwriter as follows:

              (a) Compliance with Securities Regulations and Commission
       Requests. The Company, subject to Section 3(b), will comply with the
       requirements of Rule 430A and will notify the Underwriters immediately,
       and confirm the notice in writing, (i) when any post-effective amendment
       to the Registration Statement shall become effective, or any supplement
       to the Prospectus or any amended Prospectus shall have been filed, (ii)
       of the receipt of any comments from the Commission, (iii) of any request
       by the Commission for any amendment to the Registration Statement or any
       amendment or supplement to the Prospectus or for additional information,
       and (iv) of the issuance by the Commission of any stop order suspending
       the effectiveness of the Registration Statement or of any order
       preventing or suspending the use of any preliminary prospectus, or of the
       suspension of the qualification of the Securities for offering or sale in
       any jurisdiction, or of the initiation or threatening of any proceedings
       for any of such purposes. The Company will promptly effect the filings
       necessary pursuant to Rule 424(b) and will take such steps as it deems
       necessary to ascertain promptly whether the form of prospectus
       transmitted for filing under Rule 424(b) was received for filing by the
       Commission and, in the event that it was not, it will promptly file such
       prospectus. The Company will make every reasonable effort to prevent the
       issuance of any stop order and, if any stop order is issued, to obtain
       the lifting thereof at the earliest possible moment.

              (b) Filing of Amendments. The Company will give the Underwriters
       notice of its intention to file or prepare any amendment to the
       Registration Statement (including any filing under Rule 462(b)), or any
       amendment, supplement or revision to either the prospectus included in
       the Registration Statement at the time it became effective or to the
       Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise,
       will furnish the



                                       12
<PAGE>   15

       Underwriters with copies of any such documents a reasonable amount of
       time prior to such proposed filing or use, as the case may be, and will
       not file or use any such document to which the Underwriters or counsel
       for the Underwriters shall reasonably object.

              (c) Delivery of Registration Statements. The Company has furnished
       or will deliver to the Underwriters and counsel for the Underwriters,
       without charge, signed copies of the Registration Statement as originally
       filed and of each amendment thereto (including exhibits filed therewith
       or incorporated by reference therein and documents incorporated or deemed
       to be incorporated by reference therein) and signed copies of all
       consents and certificates of experts, and will also deliver to the
       Underwriters, without charge, a conformed copy of the Registration
       Statement as originally filed and of each amendment thereto (without
       exhibits) for each of the Underwriters. The copies of the Registration
       Statement and each amendment thereto furnished to the Underwriters will
       be identical to the electronically transmitted copies thereof filed with
       the Commission pursuant to EDGAR, except to the extent permitted by
       Regulation S-T.

              (d) Delivery of Prospectuses. The Company has delivered to each
       Underwriter, without charge, as many copies of each preliminary
       prospectus as such Underwriter reasonably requested, and the Company
       hereby consents to the use of such copies for purposes permitted by the
       1933 Act. The Company will furnish to each Underwriter, without charge,
       during the period when the Prospectus is required to be delivered under
       the 1933 Act or the 1934 Act, such number of copies of the Prospectus (as
       amended or supplemented) as such Underwriter may reasonably request. The
       Prospectus and any amendments or supplements thereto furnished to the
       Underwriters will be identical in all material respects to the
       electronically transmitted copies thereof filed with the Commission
       pursuant to EDGAR, except to the extent permitted by Regulation S-T.

              (e) Continued Compliance with Securities Laws. The Company will
       comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act
       and the 1934 Act Regulations so as to permit the completion of the
       distribution of the Securities as contemplated in this Agreement and in
       the Prospectus. If at any time when a prospectus is required by the 1933
       Act to be delivered in connection with sales of the Securities, any event
       shall occur or condition shall exist as a result of which it is
       necessary, in the opinion of counsel for the Underwriters or for the
       Company, to amend the Registration Statement or amend or supplement the
       Prospectus in order that the Prospectus will not include any untrue
       statements of a material fact or omit to state a material fact necessary
       in order to make the statements therein not misleading in the light of
       the circumstances existing at the time it is delivered to a purchaser, or
       if it shall be necessary, in the opinion of such counsel, at any such
       time to amend the Registration Statement or amend or supplement the
       Prospectus in order to comply with the requirements of the 1933 Act or
       the 1933 Act Regulations, the Company will promptly prepare and file with
       the Commission, subject to Section 3(b), such amendment or supplement as
       may be necessary to correct such statement or omission or to make the
       Registration Statement or the Prospectus comply with such requirements,
       and the Company will furnish to the Underwriters such number of copies of
       such amendment or supplement as the Underwriters may reasonably request.



                                       13
<PAGE>   16

              (f) Blue Sky Qualifications. The Company will use its best
       efforts, in cooperation with the Underwriters, to qualify the Securities
       for offering and sale under the applicable securities laws of such states
       and other jurisdictions as the Underwriters may designate and to maintain
       such qualifications in effect for a period of not less than one year from
       the later of the effective date of the Registration Statement and any
       Rule 462(b) Registration Statement; provided, however, that the Company
       shall not be obligated to file any general consent to service of process
       or to qualify as a foreign corporation or as a dealer in securities in
       any jurisdiction in which it is not so qualified or to subject itself to
       taxation in respect of doing business in any jurisdiction in which it is
       not otherwise so subject. In each jurisdiction in which the Securities
       have been so qualified, the Company will file such statements and reports
       as may be required by the laws of such jurisdiction to continue such
       qualification in effect for a period of not less than one year from the
       effective date of the Registration Statement and any Rule 462(b)
       Registration Statement.

              (g) Rule 158. The Company will timely file such reports pursuant
       to the 1934 Act as are necessary in order to make generally available to
       its securityholders as soon as practicable an earnings statement for the
       purposes of, and to provide the benefits contemplated by, the last
       paragraph of Section 11(a) of the 1933 Act.

              (h) Listing. The Company will use its best efforts to effect the
       listing of the Securities on the New York Stock Exchange.

              (i) Restriction on Sale of Securities. During a period of 90 days
       from the date of this Agreement, the Company will not, without the prior
       written consent of Merrill Lynch, (i) directly or indirectly, offer,
       pledge, sell, contract to sell, sell any option or contract to purchase,
       purchase any option or contract to sell, grant any option, right or
       warrant to purchase or otherwise transfer or dispose of any share of
       Common Stock or any securities convertible into or exercisable or
       exchangeable for Common Stock or file any registration statement under
       the 1933 Act with respect to any of the foregoing or (ii) enter into any
       swap or any other agreement or any transaction that transfers, in whole
       or in part, directly or indirectly, the economic consequence of ownership
       of the Common Stock, whether any such swap or transaction described in

       Company within the meaning of Section 15 of the 1933 Act or Section 20 of

       (c) Actions against Parties; Notification. Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement. In the case of parties indemnified pursuant to Section 6(a)(1) above,
counsel to the indemnified parties shall be selected by Merrill Lynch, and, in
the case of parties indemnified pursuant to Section 6(b) above, counsel to the
indemnified parties shall be selected by the Company. In case any such action is
brought against any indemnified party, and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel
satisfactory to such indemnified party; provided, however, that if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be one or more legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnifying party shall not have the right to
direct the defense of such action on behalf of such indemnified party or parties
and such indemnified party or parties shall have the right to select separate
counsel to defend such action on behalf of such indemnified party or parties.
After notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof and approval by such indemnified party
of counsel appointed to defend such action, the indemnifying party will not be



                                       21
<PAGE>   24

liable to such indemnified party under this Section 6 for legal or other
expenses, other than reasonable costs of investigation, subsequently incurred by
such indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that in
connection with such action the indemnifying party shall not be liable for the
expenses of more than one separate counsel (in addition to local counsel) in any
one action or separate but substantially similar actions in the same
jurisdiction arising out of the same general allegations or circumstances,
designated by Merrill Lynch in the case of indemnification pursuant to Section
6(a)(1) or by the Company in the case of indemnification pursuant to Section
6(b), representing the indemnified parties under Section 6 who are parties to
such action or actions) or (ii) the indemnifying party does not promptly retain
counsel satisfactory to the indemnified party, or (iii) the indemnifying party
has authorized the employment of counsel for the indemnified party at the
expense of the indemnifying party. No indemnifying party shall, without the
prior written consent of the indemnified parties, settle or compromise or
consent to the entry of any judgment with respect to any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever in respect of which indemnification or
contribution could be sought under this Section 6 or Section 7 hereof (whether
or not the indemnified parties are actual or potential parties thereto), unless
such settlement, compromise or consent (i) includes an unconditional release of
each indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

       (d) Settlement without Consent if Failure to Reimburse. If at any time an
indemnified party shall have requested in writing an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as permitted by
this Agreement, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 6(a)(1)(ii) effected without
its written consent if (i) such settlement is entered into more than 45 days
after receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.

       (e) Other Agreements with Respect to Indemnification. The provisions of
this Section shall not affect any agreement among the Company and the Selling
Stockholder with respect to indemnification.

       (f) Limitation on Liability. The liability of the Selling Stockholder
under the indemnity provisions contained in this Section 6, the contribution
provisions contained in Section 7 and for any breach of warranty set forth in
Section 1 shall be limited to an amount equal to the proceeds received by the
Selling Stockholder from the Underwriters in the offering.

       Section 7. Contribution. If the indemnification provided for in Section 6
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect



                                       22
<PAGE>   25

the relative benefits received by the Company and the Selling Stockholder on the
one hand and the Underwriters on the other hand from the offering of the
Securities pursuant to this Agreement or (ii) if the allocation provided by
clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company and the Selling Stockholder on
the one hand and of the Underwriters on the other hand in connection with the
statements or omissions which resulted in such losses, liabilities, claims,
damages or expenses, as well as any other relevant equitable considerations.

       The relative benefits received by the Company and the Selling Stockholder
on the one hand and the Underwriters on the other hand in connection with the
offering of the Securities pursuant to this Agreement shall be deemed to be in
the same respective proportions as the total net proceeds from the offering of
the Securities pursuant to this Agreement (before deducting expenses) received
by the Selling Stockholder and the total underwriting discount received by the
Underwriters, in each case as set forth on the cover of the Prospectus.

       The relative fault of the Company and the Selling Stockholder on the one
hand and the Underwriters on the other hand shall be determined by reference to,
among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or the Selling Stockholder or by the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission

       The Company, the Selling Stockholder and the Underwriters agree that it
would not be just and equitable if contribution pursuant to this Section 7 were
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this Section
7. The aggregate amount of losses, liabilities, claims, damages and expenses
incurred by an indemnified party and referred to above in this Section 7 shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

       Notwithstanding the provisions of this Section 7, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of any such untrue or
alleged untrue statement or omission or alleged omission.

       No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

       For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each director of the Company, each officer of the



                                       23
<PAGE>   26

Company who signed the Registration Statement, and each person, if any, who
controls the Company or the Selling Stockholder within the meaning of Section 15
of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as the Company or the Selling Stockholder, as the case may be. The
Underwriters' respective obligations to contribute pursuant to this Section 7
are several in proportion to the number of Initial Securities set forth opposite
their respective names in Schedule A hereto and not joint.

       The provisions of this Section shall not affect any agreement among the
Company and the Selling Stockholder with respect to contribution.

       Section 8. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company or any of its
subsidiaries or the Selling Stockholder submitted pursuant hereto, shall remain
operative and in full force and effect, regardless of any investigation made by
or on behalf of any Underwriter or controlling person, or by or on behalf of the
Company or the Selling Stockholder, and shall survive delivery of the Securities
to the Underwriters.

       Section 9. Termination of Agreement.

       (a) Termination; General. The Underwriters may terminate this Agreement,
by notice to the Company and the Selling Stockholder, at any time at or prior to
Closing Time (i) if there has been, since the time of execution of this
Agreement or since the respective dates as of which information is given in the
Prospectus, any material adverse change in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the
Company and its subsidiaries considered as one enterprise, whether or not
arising in the ordinary course of business, or (ii) if there has occurred any
material adverse change in the financial markets in the United States or the
international financial markets, any outbreak of hostilities or escalation
thereof or other calamity or crisis or any change or development involving a
prospective change in national or international political, financial or economic
conditions, in each case the effect of which is such as to make it, in the
judgment of the Underwriters, impracticable to market the Securities or to
enforce contracts for the sale of the Securities, or (iii) if trading in any
securities of the Company has been suspended or materially limited by the
Commission or the New York Stock Exchange, or if trading generally on the
American Stock Exchange or the New York Stock Exchange or in the Nasdaq National
Market has been suspended or materially limited, or minimum or maximum prices
for trading have been fixed, or maximum ranges for prices have been required, by
any of said exchanges or by such system or by order of the Commission, the NASD
or any other governmental authority, or (iv) if a banking moratorium has been
declared by either Federal or New York authorities.

       (b) Liabilities. If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 6, 7 and 8 shall survive such termination and remain in full force and
effect.

       Section 10. Default by One or More of the Underwriters. If one or more of
the Underwriters shall fail at Closing Time or a Date of Delivery to purchase
the Securities which it or they are obligated to purchase under this Agreement
(the "Defaulted Securities"), the non-



                                       24
<PAGE>   27

defaulting Underwriters shall have the right, but not the obligation, within 24
hours thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the Defaulted Securities in such amounts as may be agreed upon and upon the
terms herein set forth; if, however, the non-defaulting Underwriters shall not
have completed such arrangements within such 24-hour period, then this Agreement
shall terminate without liability on the part of any non-defaulting Underwriter.

       No action pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

       In the event of any such default which does not result in a termination
of this Agreement, either (i) the non-defaulting Underwriters or (ii) the
Company and the Selling Stockholder shall have the right to postpone the Closing
Time or a Date of Delivery for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or Prospectus or in
any other documents or arrangement.

       Section 11. Default by the Selling Stockholder. If the Selling
Stockholder shall fail at Closing Time or at a Date of Delivery to sell and
deliver the number of Securities which the Selling Stockholder is obligated to
sell hereunder, then the Underwriters may, by notice from the Underwriters to
the Company and the Selling Stockholder, either (i) terminate this Agreement
without any liability on the fault of any non-defaulting party except that the
provisions of Sections 1, 4, 6, 7 and 8 shall remain in full force and effect or
(ii) elect to purchase the Securities which the Selling Stockholder has agreed
to sell hereunder. No action taken pursuant to this Section 11 shall relieve the
Selling Stockholder from liability, if any, in respect of such default; but the
Selling Stockholder shall in no event be liable to any of the several
Underwriters for damages on account of loss of anticipated profits from the sale
of the Securities. In the event of a default by the Selling Stockholder as
referred to in this Section 11, the Underwriters shall have the right to
postpone Closing Time or Date of Delivery for a period not exceeding seven days
in order to effect any required change in the Registration Statement or
Prospectus or in any other documents or arrangements.

       Section 12. Notices. All notices and other communications hereunder shall
be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication. Notices to the
Underwriters shall be directed to Merrill Lynch at 4 World Financial Center
Floor __, New York, New York 10080 and 3300 Hillview Avenue, Suite 150, Palo
Alto, California 94304, attention of Mathew M. Pendo; notices to the Company

                                       25

Stockholder and their respective successors. Nothing expressed or mentioned in
this Agreement is intended or shall be construed to give any person, firm or
corporation, other than the Underwriters, the Company and the Selling
Stockholder and their respective successors and the controlling persons and
officers and directors referred to in Sections 6 and 7 and their heirs and legal
representatives, any legal or equitable right, remedy or claim under or in
respect of this Agreement or any provision herein contained. This Agreement and
all conditions and provisions hereof are intended to be for the sole and
exclusive benefit of the Underwriters, the Company and the Selling Stockholder
and their respective successors, and said controlling persons and officers and
directors and their heirs and legal representatives, and for the benefit of no
other person, firm or corporation. No purchaser of Securities from any
Underwriter shall be deemed to be a successor by reason merely of such purchase.

AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. EXCEPT AS
OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

                      FORM OF OPINION OF COMPANY'S COUNSEL
                    TO BE DELIVERED PURSUANT TO SECTION 5(b)


               (i) The Company has been duly incorporated and is validly
existing as a corporation in good standing under the laws of the State of
Delaware.

               (ii) The Company has corporate power and authority to own, lease
and operate its properties and to conduct its business as described in the
Prospectus and to enter into and perform its obligations under the Purchase
Agreement.

               (iii) The Company is duly qualified as a foreign corporation to
transact business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or leasing of
property or the conduct of business, except where the failure so to qualify or
to be in good standing would not result in a Material Adverse Effect.

               (iv) The authorized, issued and outstanding capital stock of the
Company is as set forth in the Prospectus under the caption "Capitalization"
(except for subsequent issuances, if any, pursuant to reservations, agreements
or employee stock or benefit plans referred to in the Prospectus or pursuant to
the exercise of convertible securities or options referred to in the
Prospectus); the shares of issued and outstanding capital stock of the Company,
including the Securities to be purchased by the Underwriters from the Selling
Stockholder, have been duly authorized and validly issued and are fully paid and
non-assessable; and none of the outstanding shares of capital stock of the
Company was issued in violation of the preemptive or other similar rights of any
securityholder of the Company.

               (v) The sale of the Securities by the Selling Stockholder is not
subject to the preemptive or other similar rights of any securityholder of the
Company.

               (vi) Each Subsidiary has been duly incorporated and is validly
existing as a corporation in good standing under the laws of the jurisdiction of
its incorporation, has corporate power and authority to own, lease and operate
its properties and to conduct its business as described in the Prospectus and is
duly qualified as a foreign corporation to transact business and is in good
standing in each jurisdiction in which such qualification is required, whether
by reason of the ownership or leasing of property or the conduct of business,
except where the failure so to qualify or to be in good standing would not
result in a Material Adverse Effect; except as otherwise disclosed in the
Registration Statement, all of the issued and outstanding capital stock of each
Subsidiary has been duly authorized and validly issued, is fully paid and
non-assessable and, except for directors' qualifying shares, to the best of our
knowledge , is owned by the Company, directly or through subsidiaries, free and
clear of any security interest, mortgage, pledge, lien, encumbrance, claim or
equity; none of the outstanding shares of capital stock of any Subsidiary was
issued in violation of the preemptive or similar rights of any securityholder of
such Subsidiary.

               (vii) The Purchase Agreement has been duly authorized, executed
and delivered by the Company.

               (viii) The Registration Statement, including any Rule 462(b)
Registration Statement, has been declared effective under the 1933 Act; any
required filing of the Prospectus pursuant to Rule 424(b) has been made in the
manner and within the time period required by Rule 424(b); and, to the best of
our knowledge, no stop order suspending the effectiveness of the Registration
Statement or any Rule 462(b) Registration Statement has been issued under the
1933 Act and no proceedings for that purpose have been instituted or are pending
or threatened by the Commission.

               (ix) The Registration Statement, including any Rule 462(b)
Registration Statement, the Rule 430A Information, the Prospectus, excluding the
documents incorporated by reference therein, and each amendment or supplement to
the Registration Statement and Prospectus, excluding the documents incorporated
by reference therein, as of their respective effective or issue dates (other
than the financial statements and supporting schedules included therein or
omitted therefrom, as to which we need express no opinion) complied as to form
in all material respects with the requirements of the 1933 Act and the 1933 Act
Regulations.

               (x) The documents incorporated by reference in the Prospectus
(other than the financial statements and supporting schedules included therein
or omitted therefrom, as to which we need express no opinion), when they became
effective or were filed with the Commission, as the case may be, complied as to
form in all material respects with the requirements of the 1933 Act or the 1934
Act, as applicable, and the rules and regulations of the Commission thereunder.

               (xi) The form of certificate used to evidence the Common Stock
complies in all material respects with all applicable statutory requirements,
with any applicable requirements of the charter and by-laws of the Company and
the requirements of the New York Stock Exchange.

               (xii) To the best of our knowledge, there is not pending or
threatened any action, suit, proceeding, inquiry or investigation, to which the
Company or any subsidiary is a party, or to which the property of the Company or
any subsidiary is subject, before or brought by any court or governmental agency
or body, domestic or foreign, which might reasonably be expected to result in a
Material Adverse Effect, or which might reasonably be expected to materially and
adversely affect the properties or assets thereof or the consummation of the
transactions contemplated in the Purchase Agreement or the performance by the
Company of its obligations thereunder.


               (xiii) The information in the Prospectus under "Risk Factors - We
have several significant stockholders and, given the low trading volume of our
stock, if they sell their shares in a short period of time, we could see an
adverse affect on the market prices of our stock" and in the Registration
Statement under Item 15, to the extent that it constitutes (a) matters of law,
(b) summaries of legal matters, the Company's charter and bylaws or legal
proceedings, or (c) legal conclusions, has been reviewed by us and is correct in
all material respects.

<PAGE>   37

               (xiv) To the best of our knowledge, there are no statutes or
regulations that are required to be described in the Prospectus that are not
described as required.

               (xv) All contracts and other documents to which the Company or
its Subsidiaries are a party and that are summarized or referenced in the
Registration Statement are, in all material respects, fairly summarized and
accurately referenced; to the best of our knowledge, there are no franchises,
contracts, indentures, mortgages, loan agreements, notes, leases or other
instruments required to be described or referred to in the Registration
Statement or to be filed as exhibits thereto other than those described or
referred to therein or filed or incorporated by reference as exhibits thereto,
and the summaries thereof or references thereto are correct in all material
respects.

               (xvi) To the best of our knowledge, neither the Company nor any
Subsidiary is in violation of its charter or by-laws and no default by the
Company or any subsidiary exists in the due performance or observance of any
material obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease or other agreement or
instrument that is described or referred to in the Registration Statement or the
Prospectus or filed or incorporated by reference as an exhibit to the
Registration Statement.


               (xvii) No filing with, or authorization, approval, consent,
license, order, registration, qualification or decree of, any court or
governmental authority or agency, domestic or foreign (other than under the 1933
Act and the 1933 Act Regulations, which have been obtained, or as may be
required under the securities or blue sky laws of the various states, as to
which we need express no opinion) is necessary or required in connection with
the due authorization, execution and delivery of the Purchase Agreement or for
the offering, issuance, sale or delivery of the Securities.

               (xviii) The execution, delivery and performance of the Purchase
Agreement and the consummation of the transactions contemplated in the Purchase
Agreement and in the Registration Statement and compliance by the Company with
its obligations under the Purchase Agreement do not and will not, whether with
or without the giving of notice or lapse of time or both, conflict with or
constitute a breach of, or default or Repayment Event (as defined in Section
1(a)(xi) of the Purchase Agreement) under or result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of the
Company or any subsidiary pursuant to any contract, indenture, mortgage, deed of
trust, loan or credit agreement, note, lease or any other agreement or
instrument, known to us, to which the Company or any subsidiary is a party or by
which it or any of them may be bound, or to which any of the property or assets
of the Company or any subsidiary is subject (except for such conflicts, breaches
or defaults or liens, charges or encumbrances that would not have a Material
Adverse Effect), nor will such action result in any violation of the provisions
of the charter or by-laws of the Company or any subsidiary, or any applicable
law, statute, rule, regulation, judgment, order, writ or decree, known to us of
any government, government instrumentality or court, domestic or foreign, having
jurisdiction over the Company or any subsidiary or any of their respective
properties, assets or operations.

               (xix) The Company is not an "investment company" or an entity
"controlled" by an "investment company," as such terms are defined in the
Investment Company Act of 1940, as amended.

            Nothing has come to our attention that would lead us to believe that
the Registration Statement or any amendment thereto, including the Rule 430A
Information (except for financial statements and schedules and other financial
data included or incorporated by reference therein or omitted therefrom, as to
which we need make no statement), at the time such Registration Statement or any
such amendment became effective, contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein not misleading or that the Prospectus
or any amendment or supplement thereto (except for financial statements and
schedules and other financial data included or incorporated by reference therein
or omitted therefrom, as to which we need make no statement), at the time the
Prospectus was issued, at the time any such amended or supplemented prospectus
was issued or at the Closing Time, included or includes an untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

            In rendering such opinion, such counsel may rely as to matters of
fact (but not as to legal conclusions), to the extent they deem proper, on
certificates of responsible officers of the Company and public officials. Such
opinion shall not state that it is to be governed or qualified by, or that it is
otherwise subject to, any treatise, written policy or other document relating to
legal opinions, including, without limitation, the Legal Opinion Accord of the
ABA Section of Business Law (1991).

             FORM OF OPINION OF COUNSEL FOR THE SELLING STOCKHOLDER
                    TO BE DELIVERED PURSUANT TO SECTION 5(c)

               (i) No filing with, or consent, approval, authorization, license,
order, registration, qualification or decree of, any court or governmental
authority or agency, domestic or foreign, (other than the issuance of the order
of the Commission declaring the Registration Statement effective and such
authorizations, approvals or consents as may be necessary under state securities
laws, as to which we need express no opinion) is necessary or required to be
obtained by the Selling Stockholder for the performance by the Selling
Stockholder of its obligations under the Purchase Agreement or in the Power of
Attorney and Custody Agreement, or in connection with the offer, sale or
delivery of the Securities.

               (ii) The Power of Attorney and Custody Agreement has been duly
executed and delivered by the Selling Stockholder and constitutes the legal,
valid and binding agreement of the Selling Stockholder.

               (iii) The Purchase Agreement has been duly authorized, executed
and delivered by or on behalf of the Selling Stockholder.

               (iv) Each Attorney-in-Fact has been duly authorized by the
Selling Stockholder to deliver the Securities on behalf of the Selling
Stockholder in accordance with the terms of the Purchase Agreement.

               (v) The execution, delivery and performance of the Purchase
Agreement and the Power of Attorney and Custody Agreement and the sale and
delivery of the Securities and the consummation of the transactions contemplated
in the Purchase Agreement and in the Registration Statement and compliance by
the Selling Stockholder with its obligations under the Purchase Agreement have
been duly authorized by all necessary action on the part of the Selling
Stockholder and do not and will not, whether with or without the giving of
notice or passage of time or both, conflict with or constitute a breach of, or
default under or result in the creation or imposition of any tax, lien, charge
or encumbrance upon the Securities or any property or assets of the Selling
Stockholder pursuant to, any contract, indenture, mortgage, deed of trust, loan
or credit agreement, note, license, lease or other instrument or agreement to
which the Selling Stockholder is a party or by which the Selling Stockholder may
be bound, or to which any of the property or assets of the Selling Stockholder
may be subject nor will such action result in any violation of the provisions of
the charter or by-laws of the Selling Stockholder, if applicable, or any law,
administrative regulation, judgment or order of any governmental agency or body
or any administrative or court decree having jurisdiction over the Selling
Stockholder or any of its properties.

               (vi) To the best of our knowledge, the Selling Stockholder has
valid and marketable title to the Securities to be sold by the Selling
Stockholder pursuant to the Purchase Agreement, free and clear of any pledge,
lien, security interest, charge, claim, equity or encumbrance of any kind, and
has full right, power and authority to sell, transfer and deliver such
Securities pursuant


                                      B-1
<PAGE>   40

to the Purchase Agreement. By delivery of a certificate or certificates therefor
the Selling Stockholder will transfer to the Underwriters who have purchased
such Securities pursuant to the Purchase Agreement (without notice of any defect
in the title of the Selling Stockholder and who are otherwise bona fide
purchasers for purposes of the Uniform Commercial Code) valid and marketable
title to such Securities, free and clear of any pledge, lien, security interest,
charge, claim, equity or encumbrance of any kind.

               Nothing has come to our attention that would lead us to believe
that the Registration Statement or any amendment thereto, including the Rule
430A Information (except for financial statements and schedules and other
financial data included or incorporated by reference therein or omitted
therefrom, as to which we need make no statement), at the time such Registration
Statement or any such amendment became effective, contained an untrue statement
of a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading or that the
Prospectus or any amendment or supplement thereto (except for financial
statements and schedules and other financial data included or incorporated by
reference therein or omitted therefrom, as to which we need make no statement),
at the time the Prospectus was issued, at the time any such amended or
supplemented prospectus was issued or at the Closing Time, included or includes
an untrue statement of a material fact or omitted or omits to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.
