ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 317 of the California Corporations Code allows for indemnification
of officers, directors, and other corporate agents in terms sufficiently broad
to indemnify such persons under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Act"). Article IV of the Registrant's Restated Articles of
Incorporation (Exhibit 3.1 hereto) and Article VI of the Registrant's Bylaws
(Exhibit 3.2 hereto) provide for indemnification of the Registrant's directors,
officers, employees and other agents to the extent and under the circumstances
permitted by the California Corporations Code. The Registrant has also entered
into agreements with its directors and executive officers that will require the
Registrant, among other things, to indemnify them against certain liabilities
that may arise by reason of their status or service as directors and executive
officers to the fullest extent not prohibited by law.
 
    The Underwriting Agreement (Exhibit 1.1) provides for indemnification by the
Underwriters of the Registrant, its directors and officers, and by the
Registrant of the Underwriters, for certain liabilities, including liabilities
arising under the Act, and affords certain rights of contribution with respect
thereto.
 
    See also the undertakings set out in response to Item 17 herein.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
    Since May 31, 1994, Registrant has sold and issued the following securities
which were not registered under the Act:
 
        (a) Since May 31, 1994, Registrant has granted stock options to
    employees and directors under its 1986 Incentive Stock Plan and 1996 Stock
    Option Plan covering an aggregate of 730,000 shares of Registrant's Common
    Stock, at exercise prices ranging from $3.00 to $6.00 per share.
 
        (b) Since May 1994, the Registrant issued and sold 1,000 shares of
    Common Stock to employees at $3.00 per share upon exercise of stock options
    pursuant to the Registrant's 1983 Incentive Stock Plan.
 
                                      II-1
<PAGE>
        (c) Since May 1994, the Registrant issued 1,958 shares of Common Stock
    to terminated employees at $4.00 per share representing their vested
    interest in the Employee Stock Bonus Plan.
 
    The sales and issuances of securities in the transactions described above
were deemed to be exempt from registration under the Act by virtue of Rule 701
promulgated thereunder in that they were offered and sold either pursuant to
written compensatory benefit plans or pursuant to a written contract relating to
compensation, as provided by Rule 701.
 
    In all such transactions which relied upon the exemption set forth in
Section 4(2) of the Act, the recipients of securities represented their
intentions to acquire the securities for investment only and not with a view to
or for sale in connection with any distribution thereof and appropriate legends
were affixed to the securities issued in such transactions.

ITEM 17.  UNDERTAKINGS
 
    Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the provisions referenced in Item 14 of this Registration Statement
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act, and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer, or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered hereunder, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
    The undersigned Registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Act, the
    information omitted from the form of prospectus filed as part of this
    registration statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Act shall be deemed to be part of this registration
    statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Act, each
    post-effective amendment that contains a form of prospectus shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
 
    The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing, as specified in the Underwriting Agreement, certificates in such
denomination and registered in such names as required by the Underwriters to
permit prompt delivery to each Purchaser.

On behalf of the Several
Underwriters named on
Schedule I attached hereto.

Ladies and Gentlemen:

         Aehr Test Systems, a California corporation (the "Company"), proposes,
subject to the terms and conditions contained herein, to sell to you and the
other underwriters named on Schedule I to this Agreement (the "Underwriters"),
for whom you are acting as Representatives (the "Representatives"), an aggregate
of 2,200,000 shares of the Common Stock, $0.01 par value (the "Common Stock") of
the Company.  Certain shareholders of the Company named on Schedule II hereto
(the "Selling Shareholders") propose, subject to the terms and conditions
contained herein, to sell to the Underwriters an aggregate of 1,100,000 shares
of Common Stock, in the amounts set forth opposite the names of the respective
Selling Shareholders on Schedule II.  The aggregate of 3,300,000 shares to be
sold by the Company and the Selling Shareholders is herein called the "Firm
Shares."  The respective amounts of the Firm Shares to be purchased by each of
the several Underwriters are set forth opposite their names on Schedule I
hereto, and the respective amounts of Firm Shares to be sold by the Selling
Shareholders are set forth opposite their names on Schedule II.  The Company and
the Selling Shareholders are sometimes referred to herein collectively as the
"Sellers."  In addition, certain of the Selling Shareholders propose to grant to
the Underwriters an option to purchase up to an additional 495,000 shares (the
"Option Shares") of Common Stock from them for the purpose of covering
over-allotments in connection


                                          1

<PAGE>

with the sale of the Firm Shares.  The Firm Shares and the Option Shares are
together called the "Shares."

         1.   SALE AND PURCHASE OF THE SHARES.  On the basis of the
representations, warranties and covenants contained in, and subject to the terms
and conditions of, this Agreement:

                   (a)  The Company agrees to sell to each of the Underwriters,
    and each of the Underwriters agrees, severally and not jointly, to purchase
    from the Company, at a price of $______ per share (the "Initial Price"),
    the number of Firm Shares set forth opposite the name of such Underwriter
    under the column "Number of Firm Shares to be Purchased from the Company"
    on Schedule I to this Agreement, subject to adjustment in accordance with
    Section 11 hereof.  The Selling Shareholders agree to sell to each of the
    Underwriters, and each of the Underwriters agrees, severally and not
    jointly, to purchase from the Selling Shareholders, at the Initial Price,
    the number of Firm Shares set forth opposite the name of such Underwriter
    under the column "Number of Firm Shares to be Purchased from Selling
    Shareholders" on Schedule I to this Agreement, subject to adjustment in
    accordance with Section 11 hereof.

                   (b)  Certificates in negotiable form for the total number of
    the Firm Shares to be sold hereunder by each of the Selling Shareholders
    have been placed in custody with U.S. Stock Transfer Corporation as
    custodian (the "Custodian"), pursuant to the Custody Agreement and
    Irrevocable Power of Attorney (the "Custody Agreement") executed by each
    Selling Shareholder for delivery of all Firm Shares to be sold hereunder by
    such Selling Shareholder.  Each of the Selling Shareholders specifically
    agrees that the Firm Shares represented by the certificates held in custody
    for such Selling Shareholder under the Custody Agreement are subject to the
    interests of the Underwriters hereunder, that the arrangements made by such
    Selling Shareholder for such custody are to that extent irrevocable, and
    that the obligations of such Selling Shareholder hereunder shall, subject
    to applicable law, not be terminable by any act or deed of the Selling
    Shareholder (or by any other person, firm or corporation including the
    Company, the Custodian or the Underwriters) or by operation of law
    (including the death of such Selling Shareholder) or by the occurrence of
    any other event or events, except as set forth in the Custody Agreement.
    If any such event should occur prior to the delivery to the Underwriters of
    the Firm Shares to be sold by the Selling Shareholders hereunder,
    certificates for the Firm Shares shall, except as set forth herein or in
    the Custody Agreement, be delivered by the Custodian in accordance with the
    terms and conditions of this Agreement as if such event had not occurred.
    The Custodian is authorized to receive and acknowledge receipt of the
    proceeds of the sale of the Shares to be sold by the Selling Shareholders
    held by it against delivery of such Shares.

                   (c)  The Selling Shareholders identified on Schedule II
    hereto grant to the several Underwriters an option to purchase, severally
    and not jointly, all or any part of the Option Shares at the Initial Price.
    The number of Option Shares to be purchased by each Underwriter shall be
    the same percentage (adjusted by the Representatives to eliminate
    fractions) of the total number of Option Shares to be


                                          2
<PAGE>

    purchased by the Underwriters as such Underwriter is purchasing of the Firm
    Shares.  The number of Option Shares to be sold by each of the Selling
    Shareholders identified on Schedule II hereto shall be the same percentage
    (adjusted by the Representatives to eliminate fractions) of the number of
    Option Shares set forth opposite such Selling Shareholder's name on
    Schedule II hereof as the percentage of the total number of Option Shares
    being purchased by the Underwriters.  Such option may be exercised only to
    cover over-allotments in the sale of the Firm Shares by the Underwriters
    and may be exercised in whole or in part at any time on or before 12:00
    noon, New York City time, on the business day before the Firm Shares
    Closing Date (as defined below), and from time to time thereafter within 30
    days after the date of this Agreement, in each case upon written or
    telegraphic notice, or oral or telephonic notice confirmed by written or
    telegraphic notice, by the Representatives to the Company and the Custodian
    no later than 12:00 noon, New York City time, on the business day before
    the Firm Shares Closing Date or at least two business days before the
    Option Shares Closing Date (as defined below), as the case may be, setting
    forth the number of Option Shares to be purchased and the time and date (if
    other than the Firm Shares Closing Date) of such purchase.

         2.   DELIVERY AND PAYMENT.  Delivery by the Company and the Custodian
of the Firm Shares to the Representatives for the respective accounts of the
Underwriters, and payment of the purchase price by certified or official bank
check or checks payable in New York Clearing House (next day) funds drawn to the
order of the Company for the Shares purchased from the Company and to the
Custodian for the Shares purchased from the Selling Shareholders, against
delivery of the respective certificates therefor to the Representatives, shall
take place at the offices of Oppenheimer & Co., Inc. at Oppenheimer Tower, World
Financial Center, New York, New York  10281, at 10:00 a.m., New York City time,
(a) on the third full business day following the first day that the shares are
traded, (b) if this Agreement is executed and delivered after 4:30 p.m., New
York City time, on the fourth business day following the date of this Agreement,
or (c) at such time on such other date, not later than the fourth full business
day following the Effective Date (as hereinafter defined), as shall be agreed
upon by the Company, the Selling Shareholders and the Representatives (such time
and date of delivery and payment are called the "Firm Shares Closing Date").

         In the event the option with respect to the Option Shares is
exercised, delivery by the Custodian of the Option Shares to the Representatives
for the respective accounts of the Underwriters, and payment of the purchase
price by certified or official bank check or checks payable in New York Clearing
House (next day) funds to the Custodian shall take place at the offices of
Oppenheimer & Co., Inc. specified above at the time and on the date (which may
be the same date as, but in no event shall be earlier than, the Firm Shares
Closing Date) specified in the notice referred to in Section 1(c) (such time and
date of delivery and payment are called the "Option Shares Closing Date").  The
Firm Shares Closing Date and the Option Shares Closing Date are called,
individually, a "Closing Date" and, together, the "Closing Dates."

         Certificates evidencing the Shares shall be registered in such names
and shall be in such denominations as the Representatives shall request at least
two full business days before the Firm Shares Closing Date or, in the case of
Option Shares, on the day of notice of exercise of the option as described in
Section 1(c) and shall be made available to the Representatives for


                                          3
<PAGE>

checking and packaging, at such place as is designated by the Representatives,
one full business day before the Firm Shares Closing Date (or the Option Shares
Closing Date in the case of the Option Shares).

         3.   REGISTRATION STATEMENT AND PROSPECTUS; PUBLIC OFFERING.  The
Company has prepared in conformity with the requirements of the Securities Act
of 1933, as amended (the "Securities Act"), and the published rules and
regulations thereunder (the "Rules") adopted by the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-1 (No.
333-28987), including a preliminary prospectus relating to the Shares, and has
filed with the Commission such registration statement and such amendments
thereto as may have been required to the date of this Agreement.  Copies of such
registration statement (including all amendments thereof) and of the related
preliminary prospectus have heretofore been delivered by the Company to you.
The term "preliminary prospectus" means any preliminary prospectus (as described
in Rule 430 of the Rules) included at any time as part of the registration
statement or filed with the Commission by the Company with the consent of the
Representatives pursuant to Rule 424(a) of the Rules.  The registration
statement, as amended at the time and on the date it became effective (the
"Effective Date"), including all exhibits and information, if any, deemed to be
part of the registration statement pursuant to Rule 424(b), Rule 430A and
Rule 434 of the Rules, is called the "Registration Statement."  The term
"Prospectus" as used in this Agreement means the prospectus in the form included
in the Registration Statement or (A) if Rule 430(A) of the Rules is relied on,
the term "Prospectus" means the final prospectus filed with the Commission
pursuant to Rule 424(b) of the Rules and (B) if Rule 434 of the Rules is relied
on, then (i) the term "Prospectus" means the "prospectus subject to completion"
(as such term is defined in Rule 434(g) of the Rules) together with the term
sheet (the "Term Sheet") required under Rule 434(b) of the Rules and (ii) the
date of such Prospectus shall be deemed to be the date of the Term Sheet.  If
the Company files a registration statement to register a portion of the Shares
and relies on Rule 462(b) of the Rules for such registration statement to become
effective upon filing with the Commission (the "Rule 462(b) Registration
Statement"), then any reference to the "Registration Statement" herein shall be
deemed to include both the registration statement referred to above (No. 333-
28987) and the Rule 462(b) Registration Statement, as each such registration
statement may be amended pursuant to the Securities Act.

          The Company and each of the Selling Shareholders understand that the
Underwriters propose to make a public offering of the Shares, as set forth in
and pursuant to the Prospectus, as soon after the Effective Date and the date of
this Agreement as the Representatives deem advisable.  The Company and each of
the Selling Shareholders hereby confirm that the Underwriters and dealers have
been authorized to distribute or cause to be distributed each preliminary
prospectus and are authorized to distribute the Prospectus (as from time to time
amended or supplemented if the Company furnishes amendments or supplements
thereto to the Underwriters).

         4.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company
hereby represents and warrants to each Underwriter as follows:

                   (a)  On the Effective Date, the Registration Statement
    complied, and on the date of the Prospectus, on the date any post-effective
    amendment to the


                                          4
<PAGE>

    Registration Statement becomes effective, on the date any supplement or
    amendment to the Prospectus is filed with the Commission and on each
    Closing Date, the Registration Statement and the Prospectus (and any
    amendment thereof or supplement thereto) will comply, in all material
    respects, with the applicable provisions of the Securities Act and the
    Rules; the Registration Statement did not, as of the Effective Date,
    contain any untrue statement of a material fact or omit to state any
    material fact required to be stated therein or necessary in order to make
    the statements therein not misleading; and on the other dates referred to
    above neither the Registration Statement nor the Prospectus, nor any
    amendment thereof or supplement thereto, will contain any untrue statement
    of a material fact or will omit to state any material fact required to be
    stated therein or necessary in order to make the statements therein not
    misleading.  When any related preliminary prospectus was first filed with
    the Commission (whether filed as part of the Registration Statement or any
    amendment thereto or pursuant to Rule 424(a) of the Rules) and when any
    amendment thereof or supplement thereto was first filed with the
    Commission, such preliminary prospectus as amended or supplemented complied
    in all material respects with the applicable provisions of the Securities
    Act and the Rules and did not contain any untrue statement of a material
    fact or omit to state any material fact required to be stated therein or
    necessary in order to make the statements therein not misleading; provided,
    however, that none of the representations and warranties in this
    paragraph 4(a) shall apply to statements in, or omissions from, the
    Registration Statement or the Prospectus made in reliance upon, and in
    conformity with, information herein or otherwise furnished in writing to
    the Company by the Representatives on behalf of the several Underwriters
    for use in the Registration Statement or the Prospectus.  With respect to
    the preceding sentence, the Company acknowledges that the only information
    furnished in writing by the Representatives on behalf of the several
    Underwriters for use in the Registration Statement or the Prospectus is the
    paragraph with respect to stabilization on the inside front cover page of
    the Prospectus and the statements contained under the caption
    "Underwriting" in the Prospectus.

                   (b)  The Registration Statement is effective under the
    Securities Act, and no stop order suspending the effectiveness of the
    Registration Statement or suspending or preventing the use of the
    Prospectus has been issued and no proceedings for that purpose have been
    instituted or are threatened under the Securities Act; any required filing
    of the Prospectus and any supplement thereto pursuant to Rule 424(b) of the
    Rules has been or will be made in the manner and within the time period
    required by such Rule 424(b).

                   (c)  The consolidated financial statements of the Company
    (including all notes and schedules thereto) included in the Registration
    Statement and Prospectus present fairly the financial position, the results
    of the operations, the statements of cash flows and the statements of
    shareholders' equity and the other information purported to be shown
    therein of the Company and its consolidated subsidiaries at the respective
    dates and for the respective periods to which they apply; and such
    consolidated financial statements have been prepared in conformity with
    generally accepted accounting principles, consistently applied throughout
    the periods involved, are correct and complete and are in accordance with
    the books and records of the Company


                                          5
<PAGE>

    and its consolidated subsidiaries.  The summary and selected financial data
    included in the Prospectus present fairly the information shown therein as
    at the respective dates and for the respective periods specified, and the
    summary and selected financial data have been presented on a basis
    consistent with the consolidated financial statements so set forth in the
    Prospectus and such books and records.

                   (d)  Coopers & Lybrand L.L.P., whose report is filed with
    the Commission as a part of the Registration Statement, are and, during the
    periods covered by their reports, were independent public accountants as
    required by the Securities Act and the Rules.

                   (e)  The Company and each of it Subsidiaries (as hereinafter
    defined) is a corporation duly organized, validly existing and in good
    standing under their respective jurisdictions of organization.  The Company
    has no subsidiary or subsidiaries and does not control, directly or
    indirectly, any corporation, partnership, joint venture, association or
    other business organization, except for those set forth on SCHEDULE 4(e)
    hereto.  The Company and each such subsidiary or other entity
    (collectively, "Subsidiaries") is duly qualified to do business and in good
    standing as a foreign corporation in each jurisdiction in which the
    character or location of its assets or properties (owned, leased or
    licensed) or the nature of its business makes such qualification necessary
    except for such jurisdictions where the failure to so qualify would not
    have a material adverse effect on the assets or properties, business,
    results of operations, prospects or condition (financial or otherwise) of
    the Company and its Subsidiaries considered as a whole (a "Material Adverse
    Effect").  Except as disclosed in the Prospectus, neither the Company nor
    any Subsidiary owns, leases or licenses any asset or property or conducts
    any business outside the United States.  The Company and each of its
    Subsidiaries has all requisite corporate power and authority, and all
    necessary authorizations, approvals, consents, orders, licenses,
    certificates and permits of and from all governmental or regulatory bodies
    or any other person or entity, to own, lease and license its assets and
    properties and conduct its businesses as now being conducted and as
    described in the Prospectus except for such authorizations, approvals,
    consents, orders, licenses, certificates and permits the failure to so
    obtain would not have a Material Adverse Effect; no such authorization,
    approval, consent, order, license, certificate or permit contains a
    materially burdensome restriction other than as disclosed in the
    Prospectus; and the Company has all such corporate power and authority and
    such authorizations, approvals, consents, orders, licenses, certificates
    and permits to enter into, deliver and perform this Agreement and to issue
    and sell the Shares.

                   (f)  The Company and each of its Subsidiaries owns, or
    possesses adequate and enforceable rights, either as owner or licensee, to
    use all patents, trademarks, trademark applications, trade names, service
    marks, copyrights, copyright applications, licenses, know-how and other
    similar rights and proprietary knowledge (collectively, "Intangibles")
    necessary for the conduct of its business as described in the Prospectus.
    Neither the Company nor any of its Subsidiaries has received any notice of,
    or is aware of, any infringement of or conflict with asserted rights of
    others with respect to any Intangibles.  No Intangibles of the Company or
    any Subsidiary are in dispute or are in


                                          6
<PAGE>

    any conflict with the right of any other person or entity and the Company
    and each of its Subsidiaries (i) has or will have the right to use, free
    and clear of all liens, charges, claims, encumbrances, pledges, security
    interests, defects, restrictions or equities of any kind whatsoever all
    licenses and rights to the Intangibles used in the conduct of their
    business as now conducted or proposed to be conducted without infringing
    upon or otherwise acting adversely to the right or claimed right of any
    other person and (ii) is not or will not become, as the case may be,
    obligated or in any way liable for any payment by way of royalties, fees or
    otherwise to any owner or licensee of, or other claimant to, any
    Intangibles with respect to the use thereof or in connection with the
    conduct of their business or otherwise, except in each case as disclosed in
    the Prospectus and except for any such payments, claims, uses, liens,
    charges, encumbrances, pledges, security interests, defects, restrictions
    and equities which would not have a Material Adverse Effect.

                   (g)  The Company and each of its Subsidiaries has good and
    marketable title in fee simple to each of the items of property which are
    reflected in the consolidated financial statements referred to in
    Section 4(c) or are referred to in the Registration Statement or the
    Prospectus as being owned by it and valid and enforceable leasehold
    interests in each of the items of real and personal property which are
    referred to in the Registration Statement or the Prospectus as being leased
    by it, in each case free and clear of all liens, encumbrances, claims,
    security interests and defects, other than those described in the
    Prospectus and those which do not and will not have a Material Adverse
    Effect.

                   (h)  There is no action, suit or proceeding before or by any
    court or governmental agency or body, domestic or foreign, pending or, to
    the Company's knowledge, threatened (and the Company does not know of any
    basis therefor) against or involving the assets, properties or business of,
    the Company or any of its Subsidiaries or their respective directors or
    officers which is required to be disclosed in the Prospectus that is not so
    disclosed or which, if adversely determined, could be reasonably expected
    to have a Material Adverse Effect.

                   (i)  Subsequent to the respective dates as of which
    information is given in the Registration Statement and the Prospectus,
    except as described therein, (i) there has not been any material adverse
    change in the assets or properties, business, results of operations,
    prospects or condition (financial or otherwise), of the Company or any of
    its Subsidiaries, whether or not arising from transactions in the ordinary
    course of business; (ii) neither the Company nor any of its Subsidiaries
    has sustained any loss or interference with its assets, businesses or
    properties (whether owned or leased) from fire, explosion, earthquake,
    flood or other calamity, whether or not covered by insurance, or from any
    labor dispute or any court or legislative or other governmental action,
    order or decree which would have a Material Adverse Effect; and (iii) since
    the date of the latest balance sheet included in the Registration Statement
    and the Prospectus, except as reflected therein, neither the Company nor
    any of its Subsidiaries has (A) issued any securities, (other than shares
    issued pursuant to the exercise of options granted under stock option plans
    or agreements described in the Registration Statement and Prospectus), or
    incurred any liability or obligation, direct or contingent, for borrowed
    money, except


                                          7
<PAGE>

    for borrowings under its existing credit facilities in the ordinary course
    of business, (B) entered into any transaction not in the ordinary course of
    business or (C) declared or paid any dividend or made any distribution on
    any shares of its capital stock or redeemed, purchased or otherwise
    acquired or agreed to redeem, purchase or otherwise acquire any shares of
    its stock.

                   (j)  There is no document, contract or other agreement of a
    character required to be described in the Registration Statement or
    Prospectus or to be filed as an exhibit to the Registration Statement which
    is not described or filed as required by the Securities Act or the Rules.
    Each agreement described in the Registration Statement and the Prospectus
    or listed in the Exhibits to the Registration Statement is in full force
    and effect and is valid and enforceable by and against the Company or the
    Subsidiaries, as the case may be, in accordance with its terms.  Neither
    the Company, the Subsidiaries, nor to the Company's knowledge, any other
    party is in default in the observance or performance of any term or
    obligation to be performed by it under any such agreement, and no event has
    occurred which with notice or lapse of time or both would constitute such a
    default, in any such case which default or event would have a Material
    Adverse Effect.  No default exists, and no event has occurred which with
    notice or lapse of time or both would constitute a default, in the due
    performance and observance of any term, covenant or condition, by the
    Company or any of its Subsidiaries of any other agreement or instrument to
    which the Company or any of its Subsidiaries is a party or by which any of
    them or their respective properties or businesses may be bound or affected
    which default or event would have a Material Adverse Effect.

                   (k)  Neither the Company nor any of its Subsidiaries is in
    violation of (i) any term or provision of its charter or by-laws, in each
    case amended to the date hereof or (ii) any franchise, license, permit,
    judgment, decree, order, statute, rule or regulation, where the
    consequences of such violation would have a Material Adverse Effect.

                   (l)  Neither the execution, delivery and performance of this
    Agreement by the Company nor the consummation of any of the transactions
    contemplated hereby (including, without limitation, the issuance and sale
    by the Company of the Shares) will (i) give rise to a right to terminate or
    accelerate the due date of any payment due under, or conflict with or
    result in the breach of any term or provision of, or constitute a default
    (or an event which with notice or lapse of time or both would constitute a
    default) under, or require any consent or waiver under, or result in the
    execution or imposition of any lien, charge or encumbrance upon any
    properties or assets of the Company or any of its Subsidiaries pursuant to
    the terms of, any indenture, mortgage, deed of trust or other agreement or
    instrument to which the Company or any of its Subsidiaries is a party or by
    which it or any of its Subsidiaries or any of their properties or
    businesses is bound, or any franchise, license, permit, judgment, decree,
    order, statute, rule or regulation applicable to the Company or its
    Subsidiaries or (ii) violate any provision of the charter, by-laws or other
    organizational documents of the Company or any of its Subsidiaries, in each
    case as amended to the date hereof.  No consent, approval, authorization,
    order, registration or qualification of or with any court or governmental


                                          8

    agency or body is required for the issue and sale of the Shares or the
    consummation of the other transactions contemplated by this Agreement,
    except the registration under the Securities Act of the Shares, and such
    consents, approvals, authorizations, registrations or qualifications as may
    be required under state securities or Blue Sky laws in connection with the
    purchase and distribution of the Shares by the Underwriters.

                   (m)  The Company's authorized, issued and outstanding
    capital stock is on the date hereof, and will be on the Closing Date, as
    set forth under the caption "Capitalization" in the Prospectus (except for
    subsequent issuances pursuant to outstanding options described in the
    Registration Statement and Prospectus).  The certificates evidencing the
    Shares are in due and proper legal form and have been duly authorized for
    issuance by the Company.  All of the issued and outstanding shares of
    Common Stock have been duly and validly issued and are fully paid and
    nonassessable and none of them was issued in violation of any preemptive or
    other similar right or any state or Federal securities laws.  The Shares
    have been duly authorized and the Shares to be sold by the Company, when
    issued and sold pursuant to the Agreement, will be duly and validly issued,
    fully paid and nonassessable and the Underwriters will receive good title
    to such Shares, free and clear of all liens, security interests, pledges,
    changes, claims and encumbrances.  There are no statutory, preemptive or
    other similar rights to subscribe for or to purchase or acquire any shares
    of Common Stock of the Company or any of its Subsidiaries or any such
    rights pursuant to their respective charter or by-laws, in each case as
    amended to the date hereof, or any agreement or instrument to or by which
    the Company or any of its Subsidiaries is party or bound.  Except as
    disclosed in the Prospectus, there is no outstanding option, warrant or
    other right calling for the issuance of, and there is no commitment, plan
    or arrangement to issue, any share of stock of the Company or any of its
    Subsidiaries or any security convertible into, or exercisable or
    exchangeable for, such stock.  The Common Stock and the Shares conform in
    all material respects to all statements in relation thereto contained in
    the Registration Statement and the Prospectus.  As of the date hereof and
    as of the Closing Date, all outstanding shares of capital stock of each
    Subsidiary have been and will be duly authorized and validly issued, and
    are and will be fully paid and nonassessable and owned directly by the
    Company or by another wholly-owned subsidiary of the Company free and clear
    of any security interests, liens, encumbrances, equities or claims, other
    than those described in the Prospectus.  The Company has a sufficient
    number of authorized but unissued shares of Common Stock to enable the
    Company to issue, without further shareholder action, all the Shares to be
    sold by the Company.

                   (n)  No holder of securities of the Company has rights,
    which have not been waived, to the registration of shares of Common Stock
    or other securities, as a result of the filing of the Registration
    Statement by the Company or the offering contemplated thereby.  Each
    shareholder or optionholder, holding shares, or options to purchase shares,
    representing 1.0% or more of the Company's Common Stock and each director
    and executive officer of the Company has delivered to the Representatives
    its, his or her enforceable written agreement (each, a "Lock-Up Agreement")
    in the form attached to this Agreement.  To the knowledge of the Company,
    from June 11, 1997 through the date hereof, no such shareholder, director
    or executive officer has sold any of its Common


                                          9
<PAGE>

    Stock or reduced its, his or her risk through the use of any option, put,
    call or other derivative security relative to its Common Stock.

                   (o)  All necessary corporate action has been duly and
    validly taken by the Company to authorize the execution, delivery and
    performance of this Agreement and the issuance and sale of the Shares by
    the Company and the sale of the Shares by the Selling Shareholders.  This
    Agreement has been duly and validly executed and delivered by the Company
    and constitutes and will constitute a legal, valid and binding obligation
    of the Company enforceable against the Company in accordance with its
    terms, except (i) as the enforceability thereof may be limited by
    bankruptcy, insolvency, reorganization, moratorium or other similar laws
    affecting the enforcement of creditors' rights generally and by general
    equitable principles and (ii) to the extent that rights to indemnity or
    contribution under this Agreement may be limited by Federal and state
    securities laws or the public policy underlying such laws.

                   (p)  No labor dispute with the employees of the Company or
    any of its Subsidiaries exists or, to the knowledge of the Company is
    threatened; and the Company is not aware of any existing or imminent labor
    disturbance by the employees of any of its principal suppliers or
    contractors which could have a Material Adverse Effect.  Neither the
    Company nor any of its Subsidiaries has violated any applicable safety or
    similar law applicable to its business nor any Federal or state law
    relating to discrimination in the hiring, promotion or pay of employees,
    nor any applicable Federal or state wages and hours law, nor any provisions
    of the Employee Retirement Income Security Act or the rules and regulations
    promulgated thereunder, the violation of any of which could have a Material
    Adverse Effect.  The Company is not aware of any threatened or pending
    litigation between the Company or any of its Subsidiaries and any of its
    executive officers which, if adversely determined, could have a Material
    Adverse Effect and has no reason to believe that such officers will not
    remain in the employment of the Company.

                   (q)  No transaction has occurred between or among the
    Company or any of its Subsidiaries and any of their officers or directors
    or any affiliate or affiliates of any such officer or director that is
    required to be described in and is not described in the Prospectus.

                   (r)  Neither the Company nor any of its Subsidiaries has
    taken, nor will any of them take, directly or indirectly, any action
    designed to or which might reasonably be expected to cause or result in, or
    which has constituted or which might reasonably be expected to constitute,
    the stabilization or manipulation of the price of the Common Stock.

                   (s)  Neither the Company nor any of its Subsidiaries has
    ever been denied a license, permit or authorization and the operating
    practices and procedures of the Company and each of its Subsidiaries are in
    material compliance with all applicable Federal, state and local laws,
    rules and regulations and, with respect to the Subsidiaries, the applicable
    laws of Japan and Germany.

                   (t)  The Company and each of its Subsidiaries has timely
    filed all Federal, state, local and foreign tax returns which are required
    to be filed through the date hereof, or has received extensions thereof
    (and such returns are each true, correct and complete in all material
    respects) and has paid all taxes shown on such returns and all assessments
    received by it to the extent that the same are material and have become
    due. There are no tax audits or investigations pending which if adversely
    determined would have a Material Adverse Effect, and there is no further
    liability (whether or not disclosed in such returns) or assessment for any
    such tax, and no interest or penalties accrued or accruing with respect
    thereto, except as may be set forth or adequately reserved for in the
    financial statements included in the Registration Statement and the
    Prospectus; and the amounts currently set up as provisions for taxes or
    otherwise by the Company and each of its Subsidiaries on their books and
    records are sufficient for the payment of all their unpaid Federal,
    foreign, state, county and local taxes accrued through the dates as of
    which they speak, and for which the Company and each of its Subsidiaries
    may be liable in their own right, or as a transferee of the assets of, or
    as successor to any other corporation, association, partnership, joint
    venture or other entity.

                   (u)  The books, records and accounts of the Company and each
    of its Subsidiaries accurately and fairly reflect, in reasonable detail,
    the transactions in, and dispositions of, the assets of, and the results of
    operations of, the Company and its Subsidiaries, respectively.  The Company
    and each of its Subsidiaries maintains a system of internal accounting
    controls sufficient to provide reasonable assurances that (i) transactions
    are executed in accordance with management's general or specific
    authorizations, (ii) transactions are recorded as necessary to permit
    preparation of financial statements in accordance with generally accepted
    accounting principles and to maintain asset accountability, (iii) access to
    assets is permitted only in accordance with management's general or
    specific authorization and (iv) the recorded accountability for assets is
    compared with the existing assets at reasonable intervals and appropriate
    action is taken with respect to any differences.

                   (v)  The Company and each of its Subsidiaries are insured by
    insurers of recognized financial responsibility against such losses and
    risks and in such amounts as are customary in the business in which they
    are engaged or propose to engage after giving effect to the transactions
    described in the Prospectus; and neither the Company nor any Subsidiary has
    any reason to believe that it will not be able to renew its existing
    insurance coverage as and when such coverage expires or to obtain similar
    coverage from similar insurers as may be necessary to continue their
    business at a cost that would not have a Material Adverse Effect.

                   (w)  Each approval, consent, order, authorization,
    designation, declaration or filing of, by or with any regulatory,
    administrative or other governmental body necessary in connection with the
    execution and delivery by the Company of this Agreement and the
    consummation of the transactions herein contemplated required to be
    obtained or performed by the Company (except such additional steps as may
    be required by the National Association of Securities Dealers, Inc. (the
    "NASD") or may be necessary

                   (y)  The Company and each of its Subsidiaries have such
    licenses, permits and other approvals or authorizations of and from
    governmental or regulatory authorities ("Permits") as are necessary under
    applicable law to own their respective properties and to conduct their
    respective businesses in the manner now being conducted and as described in
    the Registration Statement and the Prospectus except where the failure to
    have such Permits, individually or in the aggregate, could not be
    reasonably expected to have a Material Adverse Effect; and the Company and
    each of its Subsidiaries has fulfilled and performed all of its respective
    obligations with respect to such Permits, and no event has occurred which
    allows, or after notice or lapse of time or both would allow, revocation or
    termination thereof or result in any other impairment of the rights of the
    holder of any such Permits except such Permits which individually or in the
    aggregate do not have a Material Adverse Effect.  Neither the Company nor
    any of its Subsidiaries has ever been denied a Permit of the type referred
    to in this subsection (y).

                   (z)  There are no affiliations with the NASD among the
    Company's officers, directors or, to the best knowledge of the Company, any
    five percent or greater shareholder of the Company, except as set forth in
    the Registration Statement or otherwise disclosed in writing to the
    Representatives of the Underwriters.

                   (aa) (i) The Company and each of its Subsidiaries is in

    and is in compliance with all terms and conditions of any such permit,
    license, approval or authorization; (iv) to the Company's knowledge, no
    facts currently exist that will require the Company or any of its
    Subsidiaries to make future material capital expenditures to comply with
    Environmental Laws; and (v) no property which is or has been owned, leased
    or occupied by the Company or any of its Subsidiaries has been designated

    and delivered by or on behalf of such Selling Shareholder and constitute
    the legal, valid and binding agreement of such Selling Shareholder,

    thereof may be limited by bankruptcy, insolvency, reorganization,
    moratorium or other similar laws affecting the enforcement of creditors'
    rights generally and by general equitable principles and (ii) to the extent
    that rights to indemnity or contribution under this Agreement may be
    limited by Federal or state securities laws or the public policy underlying

    instrument binding upon such Selling Shareholder or any judgment, order or
    decree of any governmental body, agency or court having jurisdiction over
    such Selling Shareholder, or (ii) give rise to a right to terminate or
    accelerate the due date of any payment due under, or conflict with or

    default) under, or require any consent or waiver under, or result in the
    imposition of any lien, charge or encumbrance upon any properties or assets
    of such Selling Shareholder pursuant to the terms of any indenture,
    mortgage, deed of trust or other agreement or instrument by which such
    Selling Shareholder is a party or by which such Selling Shareholder is
    bound.  No consent, approval, authorization or order of or qualification
    with any governmental body or agency is required for the performance by
    such Selling Shareholder of its obligations under this Agreement, except

    Selling Shareholder hereunder and valid and marketable title to the Shares

    material fact necessary to make such information not misleading.

    Statement and Prospectus and, although such Selling Shareholder has not
    independently verified the accuracy or completeness of all the information
    contained therein, nothing has come to the attention of such Selling
    Shareholder that would lead such Selling Shareholder to believe that (i) on
    the Effective Date, the Registration Statement contained any untrue
    statement of a material fact or omitted to state any material fact required
    to be stated therein in order to make the statements made therein not
    misleading or (ii) on the Effective Date, the Prospectus contained or, on
    any Closing Date contains, any untrue statement of a material fact or
    omitted or omits to state any material fact necessary in order to make the
    statements therein, in the light of the circumstances under which they were
    made, not misleading.

    Subsidiaries which is not set forth in the Prospectus.

                   (j)  Such Selling Shareholder has not taken and will not
    take, directly or indirectly, any action designed to or that might
    reasonably be expected to cause or result in, the stabilization or

    sale or resale of the Shares.

                   (k)  Such Selling Shareholder has no actual knowledge that

         included in the Registration Statement and the Prospectus audited and
         reported on by them comply as to form in all material respects with
         the applicable accounting requirements of the Securities Act and the
         Rules;

                        (ii)  they have performed the procedures set forth in
         Statement of Accounting Standards No. 71 ("SAS 71") for a review of
         interim financial information with respect to the quarters ended
         August 31 and November 30, 1995, February 19, August 31, and
         November 30, 1996 and February 28, 1997 and that, in the course of
         such review, nothing came to the attention of such firm that leads
         them to believe that any changes need to be made in the financial
         statements for such quarters for them to be in accordance with
         generally accepted accounting principles.

                        (iii) on the basis of a reading of the amounts included
         in Registration Statement and the Prospectus under the headings
         "Summary Consolidated Financial Information" and "Selected
         Consolidated Financial Data," carrying out certain procedures,
         including a reading of the latest available interim financial
         statements of the Company and each Subsidiary (but not an examination
         in accordance with generally accepted auditing standards) which would
         not necessarily reveal matters of significance with respect to the
         comments set forth in such letter, a reading of the minutes of the
         meetings of the shareholders and directors of the Company, and
         inquiries of certain officials of the Company who have responsibility
         for financial and accounting matters of  the Company as to
         transactions and events subsequent to the date of the latest audited
         financial statements, except as disclosed in the Registration
         Statement and the Prospectus, nothing came to their attention which
         caused them to believe that:  (A) the amounts in "Summary Consolidated
         Financial Information," and "Selected Consolidated Financial Data"
         included in the Registration Statement and the Prospectus do not agree
         with the corresponding amounts in the audited or unaudited
         consolidated financial statements from which such amounts were
         derived; or (B) during the period from May 31, 1997 to a specified
         date not more than five days prior to the date of such letter there
         was any change in the consolidated capital stock or consolidated debt
         of the Company and its Subsidiaries, or any decrease in the
         consolidated current assets or consolidated total assets or
         consolidated shareholders' equity of the Company and its Subsidiaries,
         each as compared with the amounts shown on the consolidation balance
         sheet as of May 31, 1997 included in the Registration Statement, or
         any decrease from June 1, 1997 to the specified date, on a
         proportional basis with the fiscal quarter ended May 31, 1997, in net
         sales, income from operations, income before income taxes, net income
         or net income per share, except in all instances for changes,
         decreases or increases which the Registration Statement and the
         Prospectus disclose have occurred or may occur and except for such
         other changes, decreases or increases which you shall in your sole
         discretion accept.

                        (iv)  they have performed certain other procedures as
         may be permitted under generally acceptable auditing standards as a
         result of which they determined that certain information of an
         accounting, financial or statistical nature (which is limited to
         accounting, financial or statistical information derived from the
         general accounting records of the Company) set forth in the
         Registration Statement and the Prospectus and specified by the
         Representatives agrees with the accounting records of the Company and
         the Subsidiaries; and

                        (v)   based upon the procedures set forth in
         clauses (ii) and (iii) above and a reading of the amounts included in
         the Registration Statement under the headings "Summary Consolidated
         Financial Information" and "Selected Consolidated Financial Data"
         included in the Registration Statement and Prospectus and a reading of
         the financial statements, from which certain of such data were
         derived, nothing has come to their attention that gives them reason to
         believe (A) that the "Summary Consolidated Financial Information" and
         "Selected


                                          17
<PAGE>

         Consolidated Financial Data" included in the Registration Statement
         and Prospectus do not comply as to form in all material respects with
         the applicable accounting requirements of the Securities Act and the
         Rules or (B) that the information set forth therein is not fairly
         stated in relation to the financial statements included in the
         Registration Statement or Prospectus from which certain of such data
         were derived or is not in conformity with generally accepted
         accounting principles applied on a basis substantially consistent with
         that of the audited financial statements included in the Registration
         Statement and Prospectus.

    References to the Registration Statement and the Prospectus in this
    paragraph (g) are to such documents as amended and supplemented at the date
    of the letter.

                   (h)  The Representatives shall have received on each Closing
    Date from Wilson, Sonsini, Goodrich & Rosati, counsel for the Company, an
    opinion, addressed to the Representatives and dated such Closing Date, and
    stating in effect that:

                        (i)   The Company has been duly organized and is
         validly existing as a corporation in good standing under the laws of
         the State of California.  The Company is duly qualified and in good
         standing as a foreign corporation in each jurisdiction in which it
         owns or leases properties, except for such jurisdictions where the
         failure to so qualify would not have a Material Adverse Effect.

                        (ii)  The Company has all requisite corporate power and
         authority to own, lease and license its assets and properties and
         conduct its business as now being conducted and as described in the
         Registration Statement and the Prospectus and to enter into, deliver
         and perform this Agreement and to issue and sell the Shares to be sold
         by the Company hereunder.

                        (iii) The Company has authorized, issued and
         outstanding capital stock as set forth in the Registration Statement
         and the Prospectus under the caption "Capitalization;" the
         certificates evidencing the Shares are in due and proper legal form
         and have been duly authorized for issuance by the Company; all of the
         issued and outstanding shares of Common Stock of the Company have been
         duly and validly authorized and issued and are fully paid and
         nonassessable.  There are no statutory preemptive or other similar
         rights to subscribe for or to purchase or acquire any shares of Common
         Stock of the Company or any such rights pursuant to the Company's
         Articles of Incorporation or by-laws, each as amended to date, or any
         agreement filed as an exhibit to the Registration Statement or, to
         such counsel's knowledge, any other agreement.  The Shares to be sold
         by the Company hereunder when issued and sold pursuant to this
         Agreement will be duly and validly authorized and issued, fully paid
         and nonassessable and, to such counsel's knowledge, free and clear of
         all security interests, liens, encumbrances, equities or claims.  To
         such counsel's knowledge, except as disclosed in the Registration
         Statement and the Prospectus and for subsequent employee option grants
         made in the ordinary course of business, there is no outstanding
         option, warrant or other right calling for the issuance of, and no


                                          18
<PAGE>

         commitment, plan or arrangement to issue, any share of stock of the
         Company or any of its Subsidiaries, or any security convertible into,
         exercisable for, or exchangeable for stock of the Company or any of
         its Subsidiaries.  The Common Stock and the Shares conform in all
         material respects to the descriptions thereof contained in the
         Registration Statement and the Prospectus.  The Company has a
         sufficient number of authorized but unissued shares of Common Stock to
         enable the Company to issue, without further shareholder action, all
         the Shares to be sold by the Company.

                        (iv)  Each of the Lock-Up Agreements executed by the
         Company's shareholders, optionholders, directors and executive
         officers has been duly and validly delivered by such persons and
         constitutes the legal, valid and binding obligation of each such
         person enforceable against each such person in accordance with its
         terms, except as the enforceability thereof may be limited by
         applicable bankruptcy, insolvency, reorganization, moratorium or other
         similar laws affecting the enforcement of creditors' rights generally
         and by general equitable principles.

                        (v)   To such counsel's knowledge, no holder of
         securities of the Company has rights, which have not been waived, to
         the registration of shares of Common Stock or other securities, as a
         result of the filing of the Registration Statement by the Company or
         the offering contemplated thereby.

                        (vi)  All necessary corporate action has been duly and
         validly taken by the Company to authorize the execution, delivery and
         performance of this Agreement and the issuance and sale of the Shares
         by the Company and the sale of the Shares by the Selling Shareholders.
         This Agreement has been duly and validly authorized, executed and
         delivered by the Company and this Agreement constitutes the legal,
         valid and binding obligation of the Company enforceable against the
         Company in accordance with its terms except (A) as enforceability may
         be limited by applicable bankruptcy, insolvency, reorganization,
         moratorium or other similar laws affecting the enforcement of
         creditors' rights generally and by general equitable principles and
         (B) to the extent that rights to indemnity or contribution under this
         Agreement may be limited by Federal or state securities laws or the
         public policy underlying the laws.

                        (vii) Neither the execution, delivery and performance
         of this Agreement by the Company nor the consummation of any of the
         transactions contemplated hereby (including, without limitation, the
         issuance and sale by the Company of the Shares) will (A) give rise to
         a right to terminate or accelerate the due date of any payment due
         under, or conflict with or result in the breach of any term or
         provision of, or constitute a default (or any event which with notice
         or lapse of time, or both, would constitute a default) under, or
         require consent or waiver under (except those which have been
         obtained), or result in the execution or imposition of any lien,
         charge or encumbrance upon any properties or assets of


                                          19
<PAGE>

         the Company pursuant to (i) the terms of any indenture, mortgage, deed
         of trust, note or other agreement or instrument of which such counsel
         is aware and to which the Company is a party or by which it or any of
         its properties or businesses is bound or (ii) any franchise, license,
         permit, judgment, decree, order, statute, rule or regulation of which
         such counsel is aware or (B) violate any provision of the Articles of
         Incorporation or by-laws of the Company, each as amended to date.

                        (viii) To such counsel's knowledge, no default exists,
         and no event has occurred which with notice or lapse of time, or both,
         would constitute a default, in the due performance and observance of
         any term, covenant or condition by the Company of any indenture,
         mortgage, deed of trust, note or any other agreement or instrument to
         which the Company is a party or by which it or any of its assets or
         properties or businesses may be bound or affected, where the
         consequences of such default could have a Material and Adverse Effect.

                        (ix)  To such counsel's knowledge, the Company is not
         in violation of any term or provision of its Articles of Incorporation
         or by-laws or any franchise, license, permit, judgment, decree, order,
         statute, rule or regulation, where the consequences of such violation
         could have a Material Adverse Effect.

                        (x)   No consent, approval, authorization or order of
         any court or governmental or regulatory agency or body is required for
         the execution, delivery or performance of this Agreement by the
         Company or the consummation of the transactions contemplated hereby or
         thereby, except such as have been obtained under the Securities Act
         and such as may be required under state securities or Blue Sky laws in
         connection with the purchase and distribution of the Shares by the
         several Underwriters.

                        (xi)  To such counsel's knowledge, there is no action,
         suit or other proceeding or investigation before any court or
         governmental agency or body, domestic or foreign, pending or
         threatened against, or involving the assets, properties or businesses
         of, the Company or its directors or officers which could have a
         Material Adverse Effect or which is required to be described in the
         Registration Statement which is not so described.

                        (xii) The statements in the Prospectus under the
         caption "Description of Capital Stock," insofar as such statements
         constitute a summary of documents referred to therein or matters of
         law, are fair summaries in all material respects and accurately
         present the information called for with respect to such documents and
         matters.  All documents, contracts and other agreements required to be
         filed as exhibits to, or described in, the Registration Statement have
         been so filed with the Commission or are fairly described in the
         Registration Statement, as the case may be.

                        (xiii) The Registration Statement, all preliminary
         prospectuses and the Prospectus and each amendment or supplement
         thereto


                                          20
<PAGE>

         (except for the financial statements and schedules and other financial
         and statistical data derived therefrom or included therein or omitted
         therefrom, as to which such counsel need express no opinion) comply as
         to form in all material respects with the requirements of the
         Securities Act and the Rules.

                        (xiv) The Registration Statement is effective under the
         Securities Act, and no stop order suspending the effectiveness of the
         Registration Statement of suspending or preventing the use of the
         Prospectus has been issued and to such counsel's knowledge, no
         proceedings for that purpose have been instituted or are threatened
         under the Securities Act; any required filing of the Prospectus and
         any supplement thereto pursuant to Rule 424(b) of the Rules has been
         made in the manner and within the time period required by such
         Rule 424(b).

                        (xv)  The registration of the Common Stock under
         Section 12(g) of the Exchange Act has become effective.

                        (xvi) The Common Stock, including the Shares, has been
         authorized for quotation on the Nasdaq National Market.

                        (xvii) The capital stock of the Company conforms in all
         material respects to the description thereof contained in the
         Prospectus under the caption "Description of Capital Stock."

                        (xviii) 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.

              To the extent deemed advisable by such counsel, they may rely as
    to matters of fact on certificates of responsible officers of the Company
    and public officials and on the opinions of other counsel satisfactory to
    the Representatives as to matters which are governed by laws other than the
    laws of the State of California or the Federal laws of the United States;
    provided that such counsel shall state that in their opinion the
    Underwriters and they are justified in relying on such other opinions.
    Copies of such certificates and other opinions shall be furnished to the
    Representatives and counsel for the Underwriters.

              In addition, such counsel shall state that such counsel has
    participated in conferences with officers and other representatives of the
    Company, representatives of the Representatives and representatives of the
    independent public accountants of the Company, at which conferences the
    contents of the Registration Statement and Prospectus and related matters
    were discussed and that, although such counsel has not undertaken to
    independently verify and does not assume any responsibility for the
    accuracy, completeness or fairness of the statements contained in the
    Registration Statement and the Prospectus (except as specified in the
    foregoing opinion), on the basis of the foregoing, no facts have come to
    the attention of such counsel which lead such counsel to believe that the
    Registration Statement at the time it became effective (except with respect
    to the


                                          21
<PAGE>

    financial statements and notes and schedules thereto and other financial
    data, as to which such counsel need express no belief) contained any 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 as amended or supplemented (except with
    respect to the financial statements and notes and schedules thereto and
    other financial data, as to which such counsel need make no statement) on
    the date thereof contained or at any Closing Date contains any untrue
    statement of a material fact or omitted 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.

                   (i)   The Representatives shall have received on each
    Closing Date from Wilson, Sonsini, Goodrich & Rosati, counsel for the
    Selling Shareholders, an opinion addressed to the Representatives and dated
    such Closing Date, and stating in effect that:

                        (i)   This Agreement has been duly and validly executed
         and delivered by or on behalf of each of the Selling Shareholders.

                        (ii)  This Agreement, the Custody Agreement, the Power
         of Attorney and the Lock-Up Agreement each constitute the legal, valid
         and binding obligation of each of the Selling Shareholders enforceable
         in accordance with their respective terms except (A) as such
         enforceability may be limited by applicable bankruptcy, insolvency,
         reorganization, moratorium or other similar laws affecting the
         enforcement of creditors' rights generally and by general equitable
         principles and (B) to the extent that rights to indemnity or
         contribution under this Agreement may be limited by Federal or state
         securities laws or the public policy underlying such laws; and each
         Selling Shareholder has full legal right, power and authority to enter
         into this Agreement and to sell, transfer and deliver in the manner
         provided in this Agreement, the Shares to be sold by such Selling
         Shareholder hereunder.

                        (iii) To such counsel's knowledge, the transfer and
         sale by each Selling Shareholder of the Shares to be sold by such
         Selling Shareholders as contemplated by this Agreement do not give
         rise to a right to terminate or accelerate the due date of any payment
         due under, or conflict with or result in the breach of any term or
         provision of, and will not conflict with, result in a breach of, or
         constitute a default under any agreement or instrument to which the
         Selling Shareholders are parties by which the Selling Shareholders or
         any of their properties may be bound, or any franchise, license,
         permit, judgment, decree, order, statute, rule or regulation.

                        (iv)  All of the Selling Shareholders' rights in the
         Shares to be sold by the Selling Shareholders pursuant to this
         Agreement, have been transferred to the Underwriters who have
         severally purchased such Shares pursuant to this Agreement, free and
         clear of adverse claims, assuming for purposes of this opinion that
         the Underwriters purchased the same in good faith


                                          22
<PAGE>

         without notice of any adverse claims.  All stock transfer and stamp
         taxes which are required to be paid in connection with the sale of the
         Shares by the Selling Shareholders have been paid.

                        (v)   No consent, approval, authorization, license,
         certificate, permit or order of any court, governmental or regulatory
         agency, authority or body or financial institution is required in
         connection with the performance of this Agreement by any of the
         Selling Shareholders or the consummation of the transactions
         contemplated hereby, including the delivery and sale of the Shares to
         be delivered and sold by the Selling Shareholders, except such as may
         be required under state securities or Blue Sky laws in connection with
         the purchase and distribution of the Shares by the several
         Underwriters.

              To the extent deemed advisable by such counsel, they may rely as
    to matters of fact on certificates of the Selling Shareholders and on the
    opinions of other counsel satisfactory to the Representatives as to matters
    which are governed by laws other than the laws of the State of California
    or the Federal laws of the United States; provided that such counsel shall
    state that in their opinion the Underwriters and they are justified in
    relying on such other opinions.  Copies of such certificates and other
    opinions shall be furnished to the Representatives and counsel for the
    Underwriters.

              In addition, such counsel shall state that such counsel has
    participated in conferences with officers and other representatives of the
    Company, representatives of the Representatives and representatives of the
    independent public accountants of the Company, at which conferences the
    contents of the Registration Statement and the Prospectus and related
    matters were discussed and that, although such counsel has not undertaken
    to independently verify and does not assume any responsibility for the
    accuracy, completeness or fairness of the statements contained in the
    Registration Statement and the Prospectus (except as specified in the
    foregoing opinion), on the basis of the foregoing, no facts have come to
    the attention of such counsel which lead such counsel to believe that the
    Registration Statement at the time it became effective (except with respect
    to the financial statements and notes and schedules thereto and other
    financial data, as to which such counsel need express no belief) contained
    any 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 as amended or supplemented (except
    with respect to the financial statements and notes and schedules thereto
    and other financial data, as to which such counsel need make no statement)
    on the date thereof contained or at any Closing Date contains any untrue
    statement of a material fact or omitted to state a material fact necessary
    in order to make the statements therein, in light of the circumstances

         and is validly existing as a corporation in good standing under the
         laws of Japan and is duly qualified and in good standing as a foreign
         corporation in each jurisdiction in which the character or location of
         its assets or properties (owned, leased or licensed) or the nature of
         its business makes such qualification necessary, except for such
         jurisdictions where the failure to so qualify would not have a
         material adverse effect on the assets, properties, business, results
         of operations, prospects or condition (financial or otherwise) of the
         Japanese Subsidiary.

                        (ii)  The Japanese Subsidiary has all requisite
         corporate power and authority to own, lease and license its assets and
         properties and to conduct its business as now being conducted and as

                        (iii) All of the outstanding shares of capital stock of
         the Japanese Subsidiary have been duly and validly authorized and
         issued and are fully paid and nonassessable and, except as otherwise
         described in the Registration Statement and Prospectus are owned by
         the Company (except for ____________________ shares which are held of
         record by _________________________) and, to the knowledge of such
         counsel, there is no outstanding option, warrant or other right
         calling for the issuance of, and there is no commitment, plan or
         arrangement to issue any shares of capital stock of the Japanese
         Subsidiary or any security, convertible or exchangeable or exercisable
         for capital stock of the Japanese Subsidiary.

                        (iv)  Neither the execution, delivery and performance
         of this Agreement by the Company nor the consummation of any of the
         transactions contemplated hereby (including, without limitation, the
         issuance and sale by the Company of the Shares) will (A) give rise to
         a  right to terminate or accelerate the due date of any payment due
         under, or conflict with or result in the breach of any term or
         provision of, or constitute a default (or any event which with notice
         or lapse of time, or both, would constitute a default) under, or
         require consent or waiver under (except those which have been
         obtained), or result in the execution or imposition of any lien,
         charge or encumbrance upon any property or assets of the Japanese
         Subsidiary pursuant to (i) the terms of any indenture, mortgage, deed
         of  trust, note or other agreement or instrument of which such counsel
         is aware and to which the Japanese Subsidiary is a party by which it
         or any of its properties or business is bound or (ii) any franchise,
         license, permit, judgment, decree, order, statute, rule or regulation
         of which such counsel is aware or (B) violate any provision of the
         charter or bylaws of the Japanese Subsidiary, each as amended to date.

                        (v)   To such counsel's knowledge, no default exists,
         and no event has occurred which with notice or lapse of time, or both,
         would constitute a default, in the due performance and observance of
         any term, covenant or condition by the Japanese Subsidiary of any
         indenture, mortgage, deed of trust,


                                          24
<PAGE>

         note or any other agreement or instrument to which the Japanese
         Subsidiary is a party or by which it or any of its assets or
         properties or businesses may be bound or effected, where the
         consequences of such default could have a material and adverse effect
         on the assets, properties, business, results of operations, prospects
         or condition (financial or otherwise) of the Japanese Subsidiary.

                        (vi)  To such counsel's knowledge, the Japanese
         Subsidiary is not in violation of any term or provision of its charter
         or bylaws or any franchise, license, permit, judgment, decree, order,

         could have a material and adverse effect on the assets, properties,
         business, results of operations, prospects or condition (financial or
         otherwise) of the Japanese Subsidiary.

                        (vii) To such counsel's knowledge, there is no action,
         suit or other proceeding or investigation before any court or
         governmental agency or body, domestic or foreign, pending or
         threatened against, or involving the assets, properties or businesses
         of  the Japanese Subsidiary or its directors or officers which could
         have a material adverse effect on the assets, properties, business,
         results of operations, prospects or condition (financial or otherwise)
         of the Japanese Subsidiary.

              To the extent deemed advisable by such counsel, they may rely as
    to matters of fact on certificates of responsible officers of the Japanese
    Subsidiary and public officials and on the opinions of other counsel
    satisfactory to the Representatives as to matters which are governed by
    laws other than the laws of Japan; provided that such counsel shall state
    that in their opinion the Underwriters and they are justified in relying on
    such opinions.  Copies of such certificates and other opinions shall be
    furnished to the Representatives and counsel for the Underwriters.

                   (a)  The Company covenants and agrees with the several
    Underwriters as follows:

                        (i)   The Company shall prepare the Prospectus in a
         form approved by the Representatives and file such Prospectus pursuant
         to Rule 424(b) under the Securities Act not later than the
         Commission's close of business on the second business day following
         the execution and delivery of this Agreement, or, if


                                          27
<PAGE>

         applicable, such earlier time as may be required by Rule 430(a)(3) or
         Rule 434 under Securities Act.

                        (ii)  The Company shall promptly advise the
         Representatives (A) when any amendment to the Registration Statement
         shall have become effective, (B) of any request by the Commission for
         any amendment of the Registration Statement or the Prospectus or for
         any additional information, (C) of the prevention or suspension of the
         use of any preliminary prospectus or the Prospectus or of the issuance
         by the Commission of any stop order suspending the effectiveness of
         the Registration Statement or the institution or threatening of any
         proceeding for that purpose and (D) of the receipt by the Company of
         any notification with respect to the suspension of the qualification
         of the Shares for sale in any jurisdiction or the initiation or
         threatening of any proceeding for such purpose.  The Company shall not
         file any amendment of the Registration Statement or supplement to the
         Prospectus unless the Company has furnished the Representatives a copy
         for its review prior to filing and shall not file any such proposed
         amendment or supplement to which the Representatives reasonably
         object.  The Company shall use its best efforts to prevent the

                        (iii) If, at any time when a Prospectus relating to the
         Shares is required to be delivered under the Securities Act and the
         Rules, any event occurs as a result of which the Prospectus as then
         amended or supplemented would include any untrue statement of material
         fact or omit to state any material fact necessary to make the
         statements therein in the light of the circumstances under which they
         were made not misleading, or if it shall be necessary to amend or
         supplement the Prospectus to comply with the Securities Act or the
         Rules, the Company promptly shall prepare and file with the
         Commission, subject to the second sentence of paragraph (ii) of this
         Section 7(a) an amendment or supplements which shall correct such
         statement or omission or an amendment which shall effect such
         compliance.

                        (iv)  The Company shall make generally available to its
         security holders and to the Representatives as soon as practicable,
         but not later than 45 days after the end of the 12-month period
         beginning at the end of the fiscal quarter of the Company during which
         the Effective Date occurs (or 90 days if such 12-month period
         coincides with the Company's fiscal year), an earning statement (which
         need not be audited) of the Company, covering such 12-month period,

         Act or Rule 158 of the Rules.

                        (v)   The Company shall make generally available to its
         security holders and to the Representatives as soon as practicable,
         but not later than 45 days after the end of each fiscal quarter in
         each fiscal year of the Company, a balance sheet of the Company as of
         the end of such fiscal quarter and statements of operations and cash
         flows of the Company for the portion of such fiscal year


                                          28

         ended the last day of such fiscal quarter, all in reasonable detail
         and stating in comparative form the figures as of the corresponding
         date and for the corresponding period in the previous fiscal year, all
         such material to be prepared and certified by an authorized financial
         officer of the Company.

                        (vi)  The Company shall furnish to the Representatives
         and counsel for the Underwriters, without charge, signed copies of the
         Registration Statement (including all exhibits thereto and amendments
         thereof) and to each other Underwriter a copy of the Registration
         Statement (without exhibits thereto) and all amendments thereof and,
         so long as delivery of a prospectus by an Underwriter or dealer may be
         required by the Securities Act or the Rules, as many copies of any
         preliminary prospectus and the Prospectus and amendments thereof and
         supplements thereto as the Representatives may reasonably request.

                        (vii) In the event it becomes necessary to qualify the
         Shares for sale in various states, the Company shall cooperate with
         the Representatives and their counsel in endeavoring to qualify the
         Shares for offer and sale in connection with this offering under the
         state Blue Sky laws of such jurisdictions as the Representatives may
         designate and shall maintain such qualifications in effect so long as
         required for the distribution of the Shares; provided, however, that
         the Company shall not be required in connection therewith, as a
         condition thereof, to qualify as a foreign corporation or to execute a
         general consent to service of process in any jurisdiction or subject
         itself to taxation as doing business in any jurisdiction.

                        (viii) For a period of five years after the date of
         this Agreement, the Company shall supply to the Representatives, and
         to each other Underwriter who may so request in writing, copies of
         such financial statements and other periodic and special reports as
         the Company may from time to time distribute generally to the holders
         of any class of its capital stock and to furnish to the
         Representatives a copy of each annual or other report it shall be
         required to file with the Commission (including the Report on Form SR
         required by Rule 463 of the Rules).

                        (ix)  Without the prior written consent of
         Oppenheimer & Co., Inc., for a period of 180 days after the date of
         this Agreement, the Company shall not issue, sell or register (other
         than on Form S-8 or on a successor form), or otherwise dispose of,

         (B) any registration is effected on Form S-8 or on any successor form
         relating to options that are exercisable during such 180-day period,

         prior written consent of Oppenheimer & Co., Inc., offer for sale,
         sell, distribute, grant any option for the sale of, or otherwise

         rights with respect to, any shares of Common Stock (or any securities
         convertible into, exercisable for, or exchangeable for any shares of
         Common Stock) owned by such person.

                        (x)   On or before completion of this offering, the
         Company shall make all filings required under applicable securities

    hereby are consummated or this Agreement is terminated, all costs and
    expenses incident to the performance of the obligations of the Underwriters
    under this Agreement not payable by the Company pursuant to the preceding
    sentence, including, without limitation, the fees and disbursements of
    counsel for the Underwriters.

                   (c)  Each Selling Shareholder covenants and agrees with the
    Company that:

                        (i)   In order to document the Underwriters' compliance
         with the reporting and withholding provisions of the Internal Revenue
         Code of 1986, as amended, such Selling Shareholder shall deliver to
         you on or prior to each Closing Date a properly completed and executed
         United States Treasury Department Form W-8 or Form W-9, as applicable
         (or other applicable statement specified by Treasury Department
         regulations in lieu thereof).

                        (ii)  Such Selling Shareholder will not take, directly
         or indirectly, any action designed to cause or result in the
         stabilization or manipulation of the price of the Common Stock of the
         Company.

                        (iii) Such Selling Shareholder will not, for a period
         of 180 days from the date of this Agreement, without the prior written
         consent of Oppenheimer & Co., Inc. on behalf of the Underwriters,
         sell, grant any option for the sale of, or otherwise dispose of,
         directly or indirectly, any shares of Common Stock (or any securities
         convertible into, exercisable for, or exchangeable for any shares of
         Common Stock) owned by such Selling Shareholder.

         8.   INDEMNIFICATION.

                   (a)  The Company and the Selling Shareholders agree, jointly
    and severally, to indemnify and hold harmless each Underwriter and each
    person, if any, who controls any Underwriter within the meaning of
    Section 15 of the Securities Act or Section 20 of the Exchange Act against
    any and all losses, claims, damages and liabilities, joint or several
    (including any reasonable investigation, legal or other expenses incurred
    in connection with, and any amount paid in settlement of, any action, suit
    or proceeding or any claim asserted), to which they, or any of them, may
    become subject under the Securities Act, the Exchange Act or other Federal
    or state law or regulation, at common law or otherwise, insofar as such
    losses, claims, damages or liabilities arise out of or are based upon
    (i) any untrue statement or alleged untrue statement of a material fact
    contained in any preliminary prospectus, the Registration Statement or the
    Prospectus or any amendment thereof or supplement thereof, or arise out of
    or are based upon any omission to state therein a material fact required to
    be stated therein or necessary to make the statements therein, in light of
    the circumstances under which they were made, not misleading; or (ii) any
    breach of the representations and warranties set forth in Section 4 hereof,
    provided, however, that such indemnity shall not inure to the benefit of
    any Underwriter (or any person controlling such Underwriter) on account of
    any losses, claims, damages, or liabilities arising from the sale of the
    Shares to any person by such


                                          31
<PAGE>

    Underwriter if such untrue statement or omission or alleged untrue
    statement or omission was made in such preliminary prospectus, the
    Registration Statement or the Prospectus, or such amendment or supplement,
    in reliance upon and in conformity with information furnished in writing to
    the Company by the Representatives on behalf of any Underwriter
    specifically for use therein.  Notwithstanding the foregoing, the liability
    of a Selling Shareholder pursuant to the provisions of this Section 8(a)
    shall be limited to an amount equal to the aggregate net proceeds received
    by such Selling Shareholder from the sale of the Shares sold by the Selling
    Shareholder hereunder.  This indemnity agreement will be in addition to any
    liability which the Company and the Selling Shareholders may otherwise
    have.

                   (b)  Each Underwriter agrees, severally and not jointly, to
    indemnify and hold harmless the Company, the Selling Shareholders, each
    person, if any, who controls the Company within the meaning of Section 15
    of the Securities Act or Section 20 of the Exchange Act, each director of
    the Company, and each officer of the Company who signs the Registration
    Statement, to the same extent as the foregoing indemnity from the Company
    or the Selling Shareholders to each Underwriter, but only insofar as such
    losses, claims, damages or liabilities arise out of or are based upon any
    untrue statement or omission or alleged untrue statement or omission which
    was made in any preliminary prospectus, the Registration Statement or the
    Prospectus, or any amendment thereof or supplement thereto, contained in
    the last paragraph of the cover page, in the paragraph relating to
    stabilization on the inside front cover page of the Prospectus and the
    statement contained under the caption "Underwriting" in the Prospectus;
    provided, however, that the obligation of each Underwriter to indemnify the
    Company or the Selling Shareholders (including any controlling person,
    director or officer thereof), as the case may be, shall be limited to an
    amount equal to the net proceeds received by the Company from such
    Underwriter.

                   (c)  Any party that proposes to assert the right to be
    indemnified under this Section will, promptly after receipt of notice of
    commencement of any action, suit or proceeding against such party in
    respect of which a claim is to be made against an indemnifying party or
    parties under this Section, notify each such indemnifying party of the
    commencement of such action, suit or proceeding, enclosing a copy of all
    papers served.  No indemnification provided for in Section 8(a) or 8(b)
    shall be available to any party who shall fail to give notice as provided
    in this Section 8(c) if the party to whom notice was not given was unaware
    of the proceeding to which such notice would have related and was
    prejudiced by the failure to give such notice but the omission so to notify
    such indemnifying party of any such action, suit or proceeding shall not
    relieve it from any liability that it may have to any indemnified party for
    contribution or otherwise than under this Section.  In case any such
    action, suit or proceeding shall be brought against any indemnified party,
    and it shall notify the indemnifying party of the commencement thereof, the
    indemnifying party shall be entitled to participate in, and, to the extent
    that it shall wish, jointly with any other indemnifying party similarly
    notified, to assume the defense thereof, with counsel reasonably
    satisfactory to such indemnified party, and after notice from the
    indemnifying party, to such indemnified party of its election so to assume
    the defense thereof and the approval by the indemnified party of such
    counsel, the


                                          32
<PAGE>

    indemnifying party shall not be liable to such indemnified party for any
    legal or other expenses, except as provided below and except for the
    reasonable costs of investigation subsequently incurred by such indemnified
    party in connection with the defense thereof.  The indemnified party shall
    have the right to employ its counsel in any such action, but the fees and
    expenses of such counsel shall be at the expense of such indemnified party
    unless (i) the employment of counsel by such indemnified party has been
    authorized in writing by the indemnifying parties, (ii) the indemnified
    party shall have reasonably concluded that there may be a conflict of
    interest between the indemnifying parties and the indemnified party in the
    conduct of the defense of such action (in which case the indemnifying
    parties shall not have the right to direct the defense of such action on
    behalf of the indemnified party) or (iii) the indemnifying parties shall
    not have employed counsel to assume the defense of such action within a
    reasonable time after notice of the commencement thereof, in each of which
    cases the fees and expenses of counsel shall be at the expense of the
    indemnifying parties.  An indemnifying party shall not be liable for any
    settlement of any action, suit, proceeding or claim effected without its
    written consent.

         9.   CONTRIBUTION.  In order to provide for just and equitable
contribution in circumstances in which the indemnification provided for in
Section 8(a) or 8(b) is due in accordance with its terms but for any reason is
held to be unavailable to or is insufficient to hold harmless an indemnified
party under Section 8(a) or 8(b), then each indemnifying party shall contribute
to the aggregate losses, claims, damages and liabilities (including any
investigation, legal and other expenses reasonably incurred in connection with,
and any amount paid in settlement of any action, suit or proceeding or any
claims asserted, but after deducting any contribution received by any person
entitled hereunder to contribution from any persons who may be liable for
contribution) to which the indemnified party may be subject in such proportion
as is appropriate to reflect the relative benefits received by the Company and
the Selling Shareholders on the one hand and the Underwriters on the other from
the offering of the Shares or, if such allocation is not permitted by applicable
law or indemnification is not available as a result of the indemnifying party
not having received notice as provide in Section 8 hereof, in such proportion as
is appropriate to reflect not only the relative benefits referred to above but
also the relative fault of the Company and the Selling Shareholders on the one
hand and the Underwriters on the other in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations.  The relative
benefits received by the Company, the Selling Shareholders and the Underwriters
shall be deemed to be in the same proportion as (1) the total proceeds from the
offering (net of underwriting discounts but before deducting expenses) received
by the Company or the Selling Shareholders, as set forth in the table on the
cover page of the Prospectus, bear to (2) the underwriting discounts received by
the Underwriters, as set forth in the table on the cover page of the Prospectus.
The relative fault of the Company, the Selling Shareholders or the Underwriters
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact related to information supplied by
the Company, the Selling Shareholders or 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 Shareholders and
the Underwriters agree that it would not be just and equitable if contribution
pursuant to this Section 9 were determined by pro rata allocation (even if the


                                          33
<PAGE>

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.  Notwithstanding the provisions of this Section 9, (i) in no
case shall any Underwriter (except as may be provided in the Agreement Among
Underwriters) be liable or responsible for any amount in excess of the
underwriting discount applicable to the Shares purchased by such Underwriter
hereunder; (ii) the Company shall be liable and responsible for any amount in
excess of such underwriting discount; and (iii) in no case shall a Selling
Shareholder be liable and responsible for any amount in excess of the aggregate
net proceeds of the sale of Shares received by the Selling Shareholder
hereunder; provided, however, that no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  For purposes of this Section 9, each person, if
any, who controls an Underwriter within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act shall have the same rights
to contribution as such Underwriter, and each person, if any, who controls the
Company within the meaning of the Section 15 of the Securities Act or
Section 20(a) of the Exchange Act, each officer of the Company who shall have
signed the Registration Statement and each director of the Company shall have
the same rights to contribution as the Company and the Selling Shareholders,
subject in each case to clauses (i) and (ii) in the immediately preceding
sentences of this Section 9.  Any party entitled to contribution will, promptly
after receipt of notice of commencement of any action, suit or proceeding
against such party in respect of which a claim for contribution may be made
against another party or parties under this Section, notify such party or
parties from whom contribution may be sought, but the omission so to notify such
party or parties from whom contribution may be sought shall not relieve the
party or parties from whom contribution may be sought from any other obligation
it or they may have hereunder or otherwise than under this Section.  No party
shall be liable for contribution with respect to any action, suit, proceeding or
claim settled without its written consent.  The Underwriters' obligations to
contribute pursuant to this Section 9 are several in proportion to their
respective underwriting commitments and not joint.

         10.  TERMINATION.  This Agreement may be terminated with respect to
the Shares to be purchased on a Closing Date by the Representatives by notifying
the Company and the Selling Shareholder at any time:

                   (a)  in the absolute discretion of the Representatives at or
    before any Closing Date:  (i) if on or prior to such date, any domestic or
    international event or act or occurrence has materially disrupted, or in
    the opinion of the Representatives will in the future materially disrupt,
    the securities markets; (ii) if there has occurred any new outbreak or
    material escalation of hostilities or other calamity or crisis the effect
    of which on the financial markets of the United States is such as to make
    it, in the judgment of the Representatives, inadvisable to proceed with the
    offering; (iii) if there shall be such a material adverse change in general
    financial, political or economic conditions or the effect of international
    conditions on the financial markets in the United States is such as to make
    it, in the judgment of the Representatives, inadvisable or impracticable to
    market the Shares; (iv) if trading in the Shares has been suspended by the
    Commission or trading generally on the New York Stock Exchange, Inc. or
    Nasdaq has been suspended or limited, or minimum or maximum ranges for
    prices for securities shall have been fixed, or maximum ranges for prices
    for securities have been required, by said exchanges or by


                                          34
<PAGE>

    order of the Commission, the NASD or any other governmental or regulatory
    authority; or (v) if a banking moratorium has been declared by any state or
    Federal authority, or

                   (b)  at or before any Closing Date, that any of the
    conditions specified in Section 6 shall not have been fulfilled when and as
    required by this Agreement.

         If this Agreement is terminated pursuant to any of its provisions,
neither the Company nor the Selling Shareholders shall be under any liability to
any Underwriter, and no Underwriter shall be under any liability to the Company
or the Selling Shareholders, except that (A) if this Agreement is terminated by
the Representatives or the Underwriters because of any failure, refusal or
inability on the part of the Company or a Selling Shareholder to comply with the
terms or to fulfill any of the conditions of this Agreement, the Company will
reimburse the Underwriters for all out-of-pocket expenses (including the
reasonable fees and disbursements of their counsel) incurred by them in
connection with the proposed purchase and sale of the Shares or in contemplation
of performing their obligations hereunder and (B) no Underwriter who shall have
failed or refused to purchase the Shares agreed to be purchased by it under this
Agreement, without some reason sufficient hereunder to justify cancellation or
termination of its obligations under this Agreement, shall be relieved of
liability to the Company, the Selling Shareholders or to the other Underwriters
for damages occasioned by its failure or refusal.

         11.  SUBSTITUTION OF UNDERWRITERS.  If one or more of the Underwriters
shall fail (other than for a reason sufficient to justify the cancellation or
termination of this Agreement under Section 10) to purchase on any Closing Date
the Shares agreed to be purchased on such Closing Date by such Underwriter or
Underwriters, the Representatives may find one or more substitute underwriters
to purchase such Shares or make such other arrangements as the Representatives
may deem advisable or one or more of the remaining Underwriters may agree to
purchase such Shares in such proportions as may be approved by the
Representatives, in each case upon the terms set forth in this Agreement.  If no
such arrangements have been made by the close of business on the business day
following such Closing Date,

                   (a)  if the number of Shares to be purchased by the
    defaulting Underwriters on such Closing Date shall not exceed 10% of the
    Shares that all the Underwriters are obligated to purchase on such Closing
    Date, then each of the nondefaulting Underwriters shall be obligated to
    purchase such Shares on the terms herein set forth in proportion to their
    respective obligations hereunder; provided, that in no event shall the
    maximum number of Shares that any Underwriter has agreed to purchase
    pursuant to Section 1 be increased pursuant to this Section 11 by more than
    one-ninth of such number of Shares without the written consent of such
    Underwriter, or

                   (b)  if the number of Shares to be purchase by the
    defaulting Underwriters on such Closing Date shall exceed 10% of the Shares
    that all the Underwriters are obligated to purchase on such Closing Date,
    then the Company shall be entitled to an additional business day within
    which it may, but is not obligated to, find one or more substitute
    underwriters reasonably satisfactory to the Representatives to purchase
    such Shares upon the terms set forth in this Agreement.


                                          35
<PAGE>

          In any such case, either the Representatives or the Company shall have
the right to postpone the applicable Closing Date for a period of not more than
five business days in order that necessary changes and arrangements (including
any necessary amendments or supplements to the Registration Statement or
Prospectus) may be effected by the Representatives and the Company.  If the
number of Shares to be purchased on such Closing Date by such defaulting
Underwriter or Underwriters shall exceed 10% of the Shares that all the
Underwriters are obligated to purchase on such Closing Date, and none of the
nondefaulting Underwriters or the Company shall make arrangements pursuant to
this Section within the period stated for the purchase of the Shares that the
defaulting Underwriters agreed to purchase, this Agreement shall terminate with
respect to the Shares to be purchased on such Closing Date without liability on
the part of any nondefaulting Underwriter to the Company or the Selling
Shareholders, and without liability on the part of the Company or the Selling
Shareholders, except in both cases as provided in Sections 7(b), 8, 9 and 10.
The provisions of this Section shall not in any way affect the liability of any
defaulting Underwriter to the Company, the Selling Shareholders or the
nondefaulting Underwriters arising out of such default.  A substitute
underwriter hereunder shall become an Underwriter for all purposes of this
Agreement.

         12.  MISCELLANEOUS.  The respective agreements, representations,
warranties, indemnities and other statements of the Company of its officers, of
the Selling Shareholders and of the Underwriters set forth in or made pursuant
to this Agreement shall remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or the
Selling Shareholders or any of the officers, directors or controlling persons
referred to in Sections 8 and 9 hereof, and shall survive delivery of and
payment for the Shares.  The provisions of Sections 7(b), 8, 9 and 10 shall
survive the termination or cancellation of this Agreement.

          This Agreement has been and is made for the benefit of the
Underwriters, the Company and the Selling Shareholders and their respective
successors and assigns, and, to the extent expressed herein, for the benefit of
persons controlling any of the Underwriters, or the Company, and directors and
officers of the Company, and their respective successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement.  The term "successors and assigns" shall not include any purchaser of
Shares from any Underwriter merely because of such purchase.

          All notices and communications hereunder shall be in writing and
mailed or delivered or by telephone or telegraph if subsequently confirmed in
writing, (a) if to the Representatives, c/o Oppenheimer & Co., Inc., Oppenheimer
Tower, World Financial Center, New York, New York 10281, Attention:  Syndicate

          This Agreement shall be governed by and construed in accordance with
the laws of the State of New York without regard to principles of conflict of
laws.
