                             Underwriting Agreement

                                                                          [Date]

BANC OF AMERICA SECURITIES LLC
BEAR, STEARNS & CO. INC.
MORGAN KEEGAN & COMPANY, INC.
JOHN G. KINNARD AND COMPANY, INCORPORATED
As Representatives of the several Underwriters
c/o BANC OF AMERICA SECURITIES LLC
600 Montgomery Street
San Francisco, California  94111

Ladies and Gentlemen:

        Introductory.  Ancor Communications, Incorporated, a Minnesota
corporation (the "Company), proposes to issue and sell to the several
underwriters named in Schedule A (the "Underwriters") an aggregate of 2,500,000
shares (the "Firm Common Shares") of its Common Stock, par value $.01 per share
(the "Common Stock").  In addition, the Company has granted to the Underwriters
an option to purchase up to an additional 375,000 shares (the "Optional Common
Shares") of Common Stock, as provided in Section 2.  The Firm Common Shares and,
if and to the extent such option is exercised, the Optional Common Shares are
collectively called the "Common Shares".  Banc of America Securities LLC
("BAS"), Bear, Stearns & Co. Inc., Morgan Keegan & Company, Inc. and John G.
Kinnard and Company, Incorporated have agreed to act as representatives of the
several Underwriters (in such capacity, the "Representatives") in connection
with the offering and sale of the Common Shares.

        The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-3 (File No.
333-82947), which contains a form of prospectus to be used in connection with
the public offering and sale of the Common Shares.  Such registration statement,
as amended, including the financial statements, exhibits and schedules thereto,
in the form in which it was declared effective by the Commission under the
Securities Act of 1933 and the rules and regulations promulgated thereunder
(collectively, the "Securities Act"), including all documents incorporated or
deemed to be incorporated by reference therein and any information deemed to be
a part thereof under the Securities Act or the Securities Exchange Act of 1934
and the rules and regulations promulgated thereunder (collectively, the
"Exchange Act") at the time of effectiveness pursuant to Rule 430A or Rule 434
under the Securities Act, is called the "Registration Statement".  Any
registration statement filed by the Company pursuant to Rule 462(b) under the
Securities Act is called the "Rule

                                      -1-


462(b) Registration Statement", and from and after the date and time of filing
of the Rule 462(b) Registration Statement the term "Registration Statement"
shall include the Rule 462(b) Registration Statement. Such prospectus, in the
form first used by the Underwriters to confirm sales of the Common Shares, is
called the "Prospectus"; provided, however, if the Company has, with the consent
of BAS, elected to rely upon Rule 434 under the Securities Act, the term
"Prospectus" shall mean the Company's prospectus subject to completion (each, a
"preliminary prospectus") dated [___] (such preliminary prospectus is called the
"Rule 434 preliminary prospectus"), together with the applicable term sheet (the
"Term Sheet") prepared and filed by the Company with the Commission under Rules
434 and 424(b) under the Securities Act and all references in this Agreement to
the date of the Prospectus shall mean the date of the Term Sheet. All references
in this Agreement to the Registration Statement, the Rule 462(b) Registration
Statement, a preliminary prospectus, the Prospectus or the Term Sheet, or any
amendments or supplements to any of the foregoing, shall include any copy
thereof filed with the Commission pursuant to its Electronic Data Gathering,
Analysis and Retrieval System ("EDGAR").

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

        The Company hereby confirms its agreement with the Underwriters as
follows:

   Section 1.  Representations and Warranties of the Company.

        The Company hereby represents, warrants and covenants to each
Underwriter as follows:

        (a) Compliance with Registration Requirements. The Registration
    Statement and any Rule 462(b) Registration Statement have been declared
    effective by the Commission under the Securities Act. The Company has
    complied to the Commission's satisfaction with all requests of the
    Commission for additional or supplemental information. No stop order
    suspending the effectiveness of the Registration Statement or any Rule

                                      -2-


    462(b) Registration Statement is in effect and no proceedings for such
    purpose have been instituted or are pending or, to the best knowledge of
    the Company, are contemplated or threatened by the Commission.

        Each preliminary prospectus and the Prospectus when filed complied in
    all material respects with the Securities Act and (except as may be
    permitted by Regulation S-T under the Securities Act), was identical in
    content to the copy thereof delivered to the Underwriters for use in
    connection with the offer and sale of the Common Shares.  Each of the
    Registration Statement, any Rule 462(b) Registration Statement and any post-
    effective amendment thereto, at the time it became effective and at all
    subsequent times, complied and will comply in all material respects with the
    Securities Act and did not and will not contain any untrue statement of a
    material fact or omit to state a material fact required to be stated therein
    or necessary to make the statements therein not misleading.  The Prospectus,
    as amended or supplemented, as of its date and at all subsequent times, did
    not and will not contain any untrue statement of a material fact or omit to
    state a material fact necessary in order to make the statements therein, in
    the light of the circumstances under which they were made, not misleading.
    The representations and warranties set forth in the two immediately
    preceding sentences do not apply to statements in or omissions from the
    Registration Statement, any Rule 462(b) Registration Statement, or any post-
    effective amendment thereto, or the Prospectus, or any amendments or
    supplements thereto, made in reliance upon and in conformity with
    information relating to any Underwriter furnished to the Company in writing
    by the Representatives expressly for use therein as set forth in Section
    8(b).  There are no contracts or other documents required to be described in
    the Prospectus or to be filed as exhibits to the Registration Statement
    which have not been described or filed as required.

        (b) Offering Materials Furnished to Underwriters. The Company has
    delivered to the Representatives four complete manually signed copies of the
    Registration Statement and of each consent and certificate of experts filed
    as a part thereof, and conformed copies of the Registration Statement
    (without exhibits) and preliminary prospectuses and the Prospectus, as
    amended or supplemented, in such quantities and at such places as the
    Representatives have reasonably requested for each of the Underwriters.

        (c) Distribution of Offering Material By the Company. The Company has
    not distributed and will not distribute, prior to the later of the Second
    Closing Date (as defined below) and the completion of the Underwriters'
    distribution of the Common Shares, any offering material in

                                      -3-


    connection with the offering and sale of the Common Shares other than a
    preliminary prospectus, the Prospectus or the Registration Statement.

        (d) The Underwriting Agreement. This Agreement has been duly authorized,
    executed and delivered by, and is a valid and binding agreement of, the
    Company, enforceable in accordance with its terms, except as rights to
    indemnification hereunder may be limited by applicable law and except as the
    enforcement hereof may be limited by bankruptcy, insolvency, reorganization,
    moratorium or other similar laws relating to or affecting the rights and
    remedies of creditors or by general equitable principles.

        (e) Authorization of the Common Shares. The Common Shares to be
    purchased by the Underwriters from the Company have been duly authorized for
    issuance and sale pursuant to this Agreement and, when issued and delivered
    by the Company pursuant to this Agreement, will be validly issued, fully
    paid and nonassessable.

        (f) No Applicable Registration or Other Similar Rights. There are no
    persons with registration or other similar rights to have any equity or debt
    securities registered for sale under the Registration Statement or included
    in the offering contemplated by this Agreement.

        (g) No Material Adverse Change. Except as otherwise disclosed in the
    Prospectus, subsequent to the respective dates as of which information is
    given in the Prospectus: (i) there has been no material adverse change, or
    any development that could reasonably be expected to result in a material
    adverse change, in the condition, financial or otherwise, or in the
    earnings, business, operations or prospects, whether or not arising from
    transactions in the ordinary course of business of the Company (any such
    change is called a "Material Adverse Change"); (ii) the Company has not
    incurred any material liability or obligation, indirect, direct or
    contingent, not in the ordinary course of business nor entered into any
    material transaction or agreement not in the ordinary course of business;
    and (iii) there has been no dividend or distribution of any kind declared,
    paid or made by the Company on any class of capital stock or repurchase or
    redemption by the Company of any class of capital stock.

        (h) Independent Accountants. KPMG Peat Marwick LLP and McGladrey &
    Pullen, LLP, who have expressed their opinion with respect to the financial
    statements (which term as used in this Agreement includes the related notes
    thereto) and supporting schedules filed with the Commission as a part of the
    Registration Statement and included in the Prospectus, are

                                      -4-


    independent public or certified public accountants as required by the
    Securities Act and the Exchange Act.

        (i) Preparation of the Financial Statements. The financial statements
    filed with the Commission as a part of the Registration Statement and
    included in the Prospectus present fairly the financial position of the
    Company as of and at the dates indicated and the results of their operations
    and cash flows for the periods specified. The supporting schedules included
    in the Registration Statement present fairly the information required to be
    stated therein. Such financial statements and supporting schedules have been
    prepared in conformity with generally accepted accounting principles as
    applied in the United States, applied on a consistent basis throughout the
    periods involved, except as may be expressly stated in the related notes
    thereto. No other financial statements or supporting schedules are required
    to be included in the Registration Statement. The financial data set forth
    in the Prospectus under the captions "Prospectus Summary--Summary Financial
    Data", "Selected Financial Data" and "Capitalization" fairly present the
    information set forth therein on a basis consistent with that of the audited
    financial statements contained in the Registration Statement.

        (j) Incorporation and Good Standing of the Company and its Subsidiaries.
    The Company has been duly incorporated and is validly existing as a
    corporation in good standing under the laws of the jurisdiction of its
    incorporation and has corporate power and authority to own, lease and
    operate its properties and to conduct its business as described in the
    Prospectus and to enter into and perform its obligations under this
    Agreement. The Company is duly qualified as a foreign corporation to
    transact business and is in good standing in each other jurisdiction in
    which such qualification is required, whether by reason of the ownership or
    leasing of property or the conduct of business, except for such
    jurisdictions where the failure to so qualify or to be in good standing
    would not, individually or in the aggregate, result in a Material Adverse
    Change. The Company has no subsidiaries.

        (k) Capitalization and Other Capital Stock Matters. The authorized,
    issued and outstanding capital stock of the Company is as set forth in the
    Prospectus under the caption "Capitalization" (other than for subsequent
    issuances, if any, pursuant to employee benefit plans or upon exercise of
    outstanding options or warrants). The Common Stock (including the Common
    Shares) conforms in all material respects to the description thereof
    contained in the Prospectus. All of the issued and outstanding shares of
    Common Stock have been duly authorized and validly issued, are fully paid

                                      -5-


    and nonassessable and have been issued in compliance with federal and state
    securities laws. None of the outstanding shares of Common Stock were issued
    in violation of any preemptive rights, rights of first refusal or other
    similar rights to subscribe for or purchase securities of the Company. There
    are no authorized or outstanding options, warrants, preemptive rights,
    rights of first refusal or other rights to purchase, or equity or debt
    securities convertible into or exchangeable or exercisable for, any capital
    stock of the Company or any of its subsidiaries other than those set forth
    in the Prospectus.

        (l) Stock Exchange Listing. The Common Stock (including the Common
    Shares) is registered pursuant to Section 12(b) of the Securities Exchange
    Act of 1934 (the "Exchange Act") and is listed on the Nasdaq National Market
    and the Pacific Stock Exchange and the Company has taken no action designed
    to, or likely to have the effect of, terminating the registration of the
    Common Stock under the Exchange Act or delisting the Common Stock from the
    Nasdaq National Market nor has the Company received any notification that
    the Commission or the National Association of Securities Dealers, LLC (the
    "NASD") or the Pacific Stock Exchange is contemplating terminating such
    registration or listing.

        (m) Non-Contravention of Existing Instruments; No Further Authorizations
    or Approvals Required. The Company is not in violation of its charter or by-
    laws or in default (or, with the giving of notice or lapse of time, would be
    in default) ("Default") under any indenture, mortgage, loan or credit
    agreement, note, contract, franchise, lease or other instrument to which the
    Company is a party or by which it may be bound, or to which any of the
    property or assets of the Company is subject (each, an "Existing
    Instrument"), except for such Defaults as would not, individually or in the
    aggregate, result in a Material Adverse Change. The Company's execution,
    delivery and performance of this Agreement and consummation of the
    transactions contemplated hereby and by the Prospectus (i) have been duly
    authorized by all necessary corporate action and will not result in any
    violation of the provisions of the charter or by-laws of the Company, (ii)
    will not conflict with or constitute a breach of, or Default under, or
    result in the creation or imposition of any lien, charge or encumbrance upon
    any property or assets of the Company pursuant to, or require the consent of
    any other party to, any Existing Instrument, except for such conflicts,
    breaches, Defaults, liens, charges or encumbrances as would not,
    individually or in the aggregate, result in a Material Adverse Change and
    (iii) will not result in any violation of any law, administrative regulation
    or administrative or court decree applicable to the Company. No consent,
    approval, authorization or

                                      -6-


    other order of, or registration or filing with, any court or other
    governmental or regulatory authority or agency is required for the Company's
    execution, delivery and performance of this Agreement and consummation of
    the transactions contemplated hereby and by the Prospectus, except such as
    have been obtained or made by the Company and are in full force and effect
    under the Securities Act, applicable state securities or blue sky laws and
    from the National Association of Securities Dealers, Inc. (the "NASD").

        (n) No Material Actions or Proceedings. Except as otherwise disclosed in
    the Prospectus, there are no legal or governmental actions, suits or
    proceedings pending or, to the best of the Company's knowledge, threatened
    (i) against or affecting the Company, (ii) which has as the subject thereof
    any officer or director of, or property owned or leased by, the Company or
    (iii) relating to environmental or discrimination matters, where in any such
    case (A) there is a reasonable possibility that such action, suit or
    proceeding might be determined adversely to the Company and (B) any such
    action, suit or proceeding, if so determined adversely, would reasonably be
    expected to result in a Material Adverse Change or adversely affect the
    consummation of the transactions contemplated by this Agreement. No material
    labor dispute with the employees of the Company exists or, to the best of
    the Company's knowledge, is threatened or imminent.

        (o) Intellectual Property Rights. The Company owns or possesses
    sufficient trademarks, trade names, patent rights, copyrights, licenses,
    approvals, trade secrets and other similar rights (collectively,
    "Intellectual Property Rights") reasonably necessary to conduct its business
    as now conducted; and the expected expiration of any of such Intellectual
    Property Rights would not result in a Material Adverse Change. The Company
    has not received any notice of infringement or conflict with asserted
    Intellectual Property Rights of others, which infringement or conflict, if
    the subject of an unfavorable decision, would result in a Material Adverse
    Change.

        (p) All Necessary Permits, etc. The Company possesses such valid and
    current certificates, authorizations or permits issued by the appropriate
    state, federal or foreign regulatory agencies or bodies necessary to conduct
    its business, and the Company has not received any notice of proceedings
    relating to the revocation or modification of, or non-compliance with, any
    such certificate, authorization or permit which, singly or in the aggregate,
    if the subject of an unfavorable decision, ruling or finding, could result
    in a Material Adverse Change.

                                      -7-


        (q) Title to Properties. The Company has good and marketable title to
    all the properties and assets reflected as owned in the financial statements
    referred to in Section 1(i) above, in each case free and clear of any
    security interests, mortgages, liens, encumbrances, equities, claims and
    other defects, except such as do not materially and adversely affect the
    value of such property and do not materially interfere with the use made or
    proposed to be made of such property by the Company. The real property,
    improvements, equipment and personal property held under lease by the
    Company are held under valid and enforceable leases, with such exceptions as
    are not material and do not materially interfere with the use made or
    proposed to be made of such real property, improvements, equipment or
    personal property by the Company.

        (r) Tax Law Compliance. The Company has filed all necessary federal,
    state and foreign income and franchise tax returns and paid all taxes
    required to be paid by it and, if due and payable, any related or similar
    assessment, fine or penalty. The Company has made adequate charges, accruals
    and reserves in the applicable financial statements referred to in Section
    1(i) above in respect of all federal, state and foreign income and franchise
    taxes for all periods as to which the tax liability of the Company has not
    been finally determined.

        (s) Company Not an "Investment Company". The Company has been advised of
    the rules and requirements under the Investment Company Act of 1940, as
    amended (the "Investment Company Act"). The Company is not, and after
    receipt of payment for the Common Shares will not be, an "investment
    company" within the meaning of Investment Company Act and will conduct its
    business in a manner so that it will not become subject to the Investment
    Company Act.

        (t) Insurance. The Company is insured by recognized, financially sound
    and reputable institutions with policies in such amounts and with such
    deductibles and covering such risks as are generally deemed adequate and
    customary for its businesses including, but not limited to, policies
    covering real and personal property owned or leased by the Company against
    theft, damage, destruction, and acts of vandalism. The Company has no reason
    to believe that it will not be able (i) to renew its existing insurance
    coverage as and when such policies expire or (ii) to obtain comparable
    coverage from similar institutions as may be necessary or appropriate to
    conduct its business as now conducted and at a cost that would not result in
    a Material Adverse Change. The Company has not been denied any insurance
    coverage which it has sought or for which it has applied.

                                      -8-


        (u) No Price Stabilization or Manipulation. The Company has not taken
    and will not take, directly or indirectly, any action designed to or that
    might be reasonably expected to cause or result in stabilization or
    manipulation of the price of the Common Stock or any other security of the
    Company to facilitate the sale or resale of the Common Shares.

        (v) Related Party Transactions. There are no business relationships or
    related-party transactions involving the Company or any other person (i)
    required to be described in the Prospectus which have not been described as
    required, or (ii) would have been required to be disclosed in the Company's
    Proxy Statement for its 1999 Annual Meeting except that such relationship or
    transaction arose or occurred after the date of the Proxy Statement for such
    Annual Meeting.

        (w) No Unlawful Contributions or Other Payments. Neither the Company
    nor, to the best of the Company's knowledge, any employee or agent of the
    Company, has made any contribution or other payment to any official of, or
    candidate for, any federal, state or foreign office in violation of any law
    or of the character required to be disclosed in the Prospectus.

        (x) Company's Accounting System. The Company maintains a system of
    accounting controls sufficient to provide reasonable assurances that (i)
    transactions are executed in accordance with management's general or
    specific authorization; (ii) transactions are recorded as necessary to
    permit preparation of financial statements in conformity with generally
    accepted accounting principles as applied in the United States and to
    maintain accountability for assets; (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 existing assets at
    reasonable intervals and appropriate action is taken with respect to any
    differences.

        (y) Compliance with Environmental Laws. Except as would not,
    individually or in the aggregate, result in a Material Adverse Change (i)
    the Company is not in violation of any federal, state, local or foreign law
    or regulation relating to pollution or protection of human health or the
    environment (including, without limitation, ambient air, surface water,
    groundwater, land surface or subsurface strata) or wildlife, including
    without limitation, laws and regulations relating to emissions, discharges,
    releases or threatened releases of chemicals, pollutants, contaminants,
    wastes, toxic substances, hazardous substances, petroleum and petroleum
    products (collectively, "Materials of Environmental Concern"), or otherwise
    relating

                                      -9-


    to the manufacture, processing, distribution, use, treatment,
    storage, disposal, transport or handling of Materials of Environment Concern
    (collectively, "Environmental Laws"), which violation includes, but is not
    limited to, noncompliance with any permits or other governmental
    authorizations required for the operation of the business of the Company
    under applicable Environmental Laws, or noncompliance with the terms and
    conditions thereof, nor has the Company received any written communication,
    whether from a governmental authority, citizens group, employee or
    otherwise, that alleges that the Company is in violation of any
    Environmental Law; (ii) there is no claim, action or cause of action filed
    with a court or governmental authority, no investigation with respect to
    which the Company has received written notice, and no written notice by any
    person or entity alleging potential liability for investigatory costs,
    cleanup costs, governmental responses costs, natural resources damages,
    property damages, personal injuries, attorneys' fees or penalties arising
    out of, based on or resulting from the presence, or release into the
    environment, of any Material of Environmental Concern at any location owned,
    leased or operated by the Company, now or in the past (collectively,
    "Environmental Claims"), pending or, to the best of the Company's knowledge,
    threatened against the Company or any person or entity whose liability for
    any Environmental Claim the Company has retained or assumed either
    contractually or by operation of law; and (iii) to the best of the Company's
    knowledge, there are no past or present actions, activities, circumstances,
    conditions, events or incidents, including, without limitation, the release,
    emission, discharge, presence or disposal of any Material of Environmental
    Concern, that reasonably could result in a violation of any Environmental
    Law or form the basis of a potential Environmental Claim against the Company
    or against any person or entity whose liability for any Environmental Claim
    the Company has retained or assumed either contractually or by operation of
    law.

        (z) ERISA Compliance. The Company and its subsidiaries and any "employee
    benefit plan" (as defined under the Employee Retirement Income Security Act
    of 1974, as amended, and the regulations and published interpretations
    thereunder (collectively, "ERISA")) established or maintained by the
    Company, or its "ERISA Affiliates" (as defined below) are in compliance in
    all material respects with ERISA. "ERISA Affiliate" means, with respect to
    the Company, any member of any group of organizations described in Sections
    414(b),(c),(m) or (o) of the Internal Revenue Code of 1986, as amended, and
    the regulations and published interpretations thereunder (the "Code") of
    which the Company is a member. No "reportable event" (as defined under
    ERISA) has occurred or is reasonably expected to occur with respect to any
    "employee benefit plan" established or maintained

                                      -10-


    by the Company or any of its ERISA Affiliates. No "employee benefit plan"
    established or maintained by the Company or any of its ERISA Affiliates, if
    such "employee benefit plan" were terminated, would have any "amount of
    unfunded benefit liabilities" (as defined under ERISA). Neither the Company
    nor any of its ERISA Affiliates has incurred or reasonably expects to incur
    any liability under (i) Title IV of ERISA with respect to termination of, or
    withdrawal from, any "employee benefit plan" or (ii) Sections 412, 4971,
    4975 or 4980B of the Code. Each "employee benefit plan" established or
    maintained by the Company or any of their ERISA Affiliates that is intended
    to be qualified under Section 401(a) of the Code is so qualified and nothing
    has occurred, whether by action or failure to act, which would cause the
    loss of such qualification.

        (aa) Year 2000. All disclosure regarding year 2000 compliance that is
    required to be described under the Securities Act (including disclosures
    required by Staff Legal Bulletin No. 5) has been included in the Prospectus.
    The Company believes that it will not incur significant operating expenses
    or costs to ensure that its information systems will be year 2000 complaint.

        (bb) Exchange Act Compliance. The documents incorporated or deemed to be
    incorporated by reference in the Prospectus, at the time they were or
    hereafter are filed with the Commission, complied and will comply in all
    material respects with the requirements of the Exchange Act, and, when read
    together with the other information in the Prospectus, at the time the
    Registration Statement and any amendments thereto become effective and at
    the First Closing Date and the Second Closing Date, as the case may be, will
    not contain an untrue statement of a material fact or omit to state a
    material fact required to be stated therein or necessary to make the facts
    required to be stated therein or necessary to make the statements therein,
    in the light of the circumstances under which they were made, not
    misleading.

        Any certificate signed by an officer of the Company and delivered to the
Representatives or to counsel for the Underwriters shall be deemed to be a
representation and warranty by the Company to each Underwriter as to the matters
set forth therein.

   Section 2.  Purchase, Sale and Delivery of the Common Shares.

        The Firm Common Shares.  The Company agrees to issue and sell to the
several Underwriters the Firm Common Shares upon the terms herein set forth.  On
the basis of the representations, warranties and agreements herein contained,
and upon the terms but subject to the conditions herein set forth, the
Underwriters agree, severally and not jointly, to purchase from the Company the
respective

                                      -11-


number of Firm Common Shares set forth opposite their names on Schedule A. The
purchase price per Firm Common Share to be paid by the several Underwriters to
the Company shall be $[___] per share.

        The First Closing Date.  Delivery of certificates for the Firm Common
Shares to be purchased by the Underwriters and payment therefor shall be made at
the offices of BAS, 600 Montgomery Street, San Francisco, California  (or such
other place as may be agreed to by the Company and the Representatives) at 6:00
a.m. San Francisco time, on [___],or such other time and date not later than
10:30 a.m. San Francisco time, on the tenth business day following the
originally contemplated First Closing Date as the Representatives shall
designate by notice to the Company (the time and date of such closing are called
the "First Closing Date").  The Company hereby acknowledges that circumstances
under which the Representatives may provide notice to postpone the First Closing
Date as originally scheduled include, but are in no way limited to, any
determination by the Company or the Representatives to recirculate to the public
copies of an amended or supplemented Prospectus or a delay as contemplated by
the provisions of Section 10.

        The Optional Common Shares; the Second Closing Date.  In addition, on
the basis of the representations, warranties and agreements herein contained,
and upon the terms but subject to the conditions herein set forth, the Company
hereby grants an option to the several Underwriters to purchase, severally and
not jointly, up to an aggregate of 375,000 Optional Common Shares from the
Company at the purchase price per share to be paid by the Underwriters for the
Firm Common Shares.  The option granted hereunder is for use by the Underwriters
solely in covering any over-allotments in connection with the sale and
distribution of the Firm Common Shares.  The option granted hereunder may be
exercised at any time (but not more than once) upon notice by the
Representatives to the Company, which notice may be given at any time within 30
days from the date of this Agreement.  Such notice shall set forth (i) the
aggregate number of Optional Common Shares as to which the Underwriters are
exercising the option, (ii) the names and denominations in which the
certificates for the Optional Common Shares are to be registered and (iii) the
time, date and place at which such certificates will be delivered (which time
and date may be simultaneous with, but not earlier than, the First Closing Date;
and in such case the term "First Closing Date" shall refer to the time and date
of delivery of certificates for the Firm Common Shares and the Optional Common
Shares).  Such time and date of delivery, if subsequent to the First Closing
Date, is called the "Second Closing Date" and shall be determined by the
Representatives and shall not be earlier than three nor later than five full
business days after delivery of such notice of exercise.  If any Optional Common
Shares are to be purchased, each

                                      -12-


Underwriter agrees, severally and not jointly, to purchase the number of
Optional Common Shares (subject to such adjustments to eliminate fractional
shares as the Representatives may determine) that bears the same proportion to
the total number of Optional Common Shares to be purchased as the number of Firm
Common Shares set forth on Schedule A opposite the name of such Underwriter
bears to the total number of Firm Common Shares. The Representatives may cancel
the option at any time prior to its expiration by giving written notice of such
cancellation to the Company.

        Public Offering of the Common Shares.  The Representatives hereby advise
the Company that the Underwriters intend to offer for sale to the public, as
described in the Prospectus, their respective portions of the Common Shares as
soon after this Agreement has been executed and the Registration Statement has
been declared effective as the Representatives, in their sole judgment, have
determined is advisable and practicable.

        Payment for the Common Shares.  Payment for the Common Shares shall be
made at the First Closing Date (and, if applicable, at the Second Closing Date)
by wire transfer of immediately available funds to the order of the Company.

        It is understood that the Representatives have been authorized, for
their own account and the accounts of the several Underwriters, to accept
delivery of and receipt for, and make payment of the purchase price for, the
Firm Common Shares and any Optional Common Shares the Underwriters have agreed
to purchase.  The Representatives individually and not as the Representatives of
the Underwriters, may (but shall not be obligated to) make payment for any
Common Shares to be purchased by any Underwriter whose funds shall not have been
received by the Representatives by the First Closing Date or the Second Closing
Date, as the case may be, for the account of such Underwriter, but any such
payment shall not relieve such Underwriter from any of its obligations under
this Agreement.

        Delivery of the Common Shares.  The Company shall deliver, or cause to
be delivered, to the Representatives for the accounts of the several
Underwriters certificates for the Firm Common Shares at the First Closing Date,
against the receipt of satisfactory evidence of the irrevocable release of a
wire transfer of immediately available funds for the amount of the purchase
price therefor.  The Company shall also deliver, or cause to be delivered, to
the Representatives for the accounts of the several Underwriters, certificates
for the Optional Common Shares the Underwriters have agreed to purchase at the
First Closing Date or the Second Closing Date, as the case may be, against the
receipt of satisfactory evidence of

                                      -13-


the irrevocable release of a wire transfer of immediately available funds for
the amount of the purchase price therefor. The certificates for the Common
Shares shall be in definitive form and registered in such names and
denominations as the Representatives shall have requested at least two full
business days prior to the First Closing Date (or the Second Closing Date, as
the case may be) and shall be made available for inspection on the business day
preceding the First Closing Date (or the Second Closing Date, as the case may
be) at a location in New York City as the Representatives may designate. Time
shall be of the essence, and delivery at the time and place specified in this
Agreement is a further condition to the obligations of the Underwriters.

        Delivery of Prospectus to the Underwriters.  Not later than 12:00 p.m.
on the second business day following the date the Common Shares are first
released by the Underwriters for sale to the public, the Company shall deliver
or cause to be delivered, copies of the Prospectus in such quantities and at
such places as the Representatives shall request.

   Section 3.  Additional Covenants of the Company.  The Company further
               covenants and agrees with each Underwriter as follows:

          (a) Representatives' Review of Proposed Amendments and Supplements.
    During such period beginning on the date hereof and ending on the later of
    the First Closing Date or such date, as in the opinion of counsel for the
    Underwriters, the Prospectus is no longer required by law to be delivered in
    connection with sales by an Underwriter or dealer (the "Prospectus Delivery
    Period"), prior to amending or supplementing the Registration Statement
    (including any registration statement filed under Rule 462(b) under the
    Securities Act) or the Prospectus (including any amendment or supplement
    through incorporation by reference of any report filed under the Exchange
    Act), the Company shall furnish to the Representatives for review a copy of
    each such proposed amendment or supplement, and the Company shall not file
    any such proposed amendment or supplement to which the Representatives
    reasonably objects.

        (b) Securities Act Compliance. After the date of this Agreement, the
    Company shall promptly advise the Representatives in writing (i) of the
    receipt of any comments of, or requests for additional or supplemental
    information from, the Commission relating to the Registration Statement,
    (ii) of the time and date of any filing of any post-effective amendment to
    the Registration Statement or any amendment or supplement to any preliminary
    prospectus or the Prospectus, (iii) of the time and date that any post-
    effective amendment to the Registration Statement becomes effective and (iv)
    of the

                                      -14-


    issuance by the Commission of any stop order suspending the effectiveness of
    the Registration Statement or any post-effective amendment thereto or of any
    order preventing or suspending the use of any preliminary prospectus or the
    Prospectus, or of any proceedings within one (1) year of the date of this
    Agreement to remove, suspend or terminate from listing or quotation the
    Common Stock from any securities exchange upon which it is listed for
    trading or included or designated for quotation, or of the threatening or
    initiation of any proceedings for any of such purposes. If the Commission
    shall enter any such stop order at any time, the Company will use its best
    efforts to obtain the lifting of such order at the earliest possible moment.
    Additionally, the Company agrees that it shall comply with the provisions of
    Rules 424(b), 430A and 434, as applicable, under the Securities Act and will
    use its reasonable efforts to confirm that any filings made by the Company
    under such Rule 424(b) were received in a timely manner by the Commission.

        (c) Amendments and Supplements to the Prospectus and Other Securities
    Act Matters. If, during the Prospectus Delivery Period, any event shall
    occur or condition exist as a result of which it is necessary to amend or
    supplement the Prospectus in order to make the statements therein, in the
    light of the circumstances when the Prospectus is delivered to a purchaser,
    not misleading, or if in the opinion of the Representatives or counsel for
    the Underwriters it is otherwise necessary to amend or supplement the
    Prospectus to comply with law, the Company agrees to promptly prepare
    (subject to Section 3(a) hereof), file with the Commission and furnish at
    its own expense to the Underwriters and to dealers, amendments or
    supplements to the Prospectus so that the statements in the Prospectus as so
    amended or supplemented will not, in the light of the circumstances when the
    Prospectus is delivered to a purchaser, be misleading or so that the
    Prospectus, as amended or supplemented, will comply with law.

        (d) Copies of any Amendments and Supplements to the Prospectus. The
    Company agrees to furnish the Representatives, without charge, during the
    Prospectus Delivery Period, as many copies of the Prospectus and any
    amendments and supplements (including any documents incorporated or deemed
    incorporated by reference therein) thereto as the Representatives may
    request.

        (e) Blue Sky Compliance. The Company shall cooperate with the
    Representatives and counsel for the Underwriters to qualify or register the
    Common Shares for sale under (or obtain exemptions from the application of)
    the state securities or blue sky laws or Canadian provincial Securities

    with such laws and shall continue such qualifications, registrations and
    exemptions in effect so long as required for the distribution of the Common
    Shares. The Company shall not be required to qualify as a foreign
    corporation or to take any action that would subject it to general service
    of process in any such jurisdiction where it is not presently qualified or
    where it would be subject to taxation as a foreign corporation. The Company
    will advise the Representatives promptly of the suspension of the
    qualification or registration of (or any such exemption relating to) the
    Common Shares for offering, sale or trading in any jurisdiction or any
    initiation or threat of any proceeding for any such purpose, and in the
    event of the issuance of any order suspending such qualification,
    registration or exemption, the Company shall use its best efforts to obtain
    the withdrawal thereof at the earliest possible moment.

        (f) Use of Proceeds. The Company shall apply the net proceeds from the
    sale of the Common Shares sold by it in the manner described under the
    caption "Use of Proceeds" in the Prospectus.

        (g) Transfer Agent. The Company shall engage and maintain, at its
    expense, a registrar and transfer agent for the Common Stock.

        (h)  Earnings Statement.  As soon as practicable, the Company will make
    generally available to its security holders and to the Representatives an
    earnings statement (which need not be audited) covering the twelve-month
    period ending September 30, 2000 that satisfies the provisions of Section
    11(a) of the Securities Act.

        (i) Periodic Reporting Obligations. During the Prospectus Delivery

    Shares as may be required under Rule 463 under the Securities Act.

        (j) Agreement Not To Offer or Sell Additional Securities. During the
    period of 120 days following the date of the Prospectus, the Company will
    not, without the prior written consent of BAS (which consent may be withheld
    at the sole discretion of BAS), directly or indirectly, sell, offer,
    contract or grant any option to sell, pledge, transfer or establish an open
    "put equivalent position" within the meaning of Rule 16a-1(h) under the
    Exchange Act, or otherwise dispose of or transfer, or announce the offering
    of, or file any registration statement under the Securities Act in respect
    of,

                                      -16-


    any shares of Common Stock, options or warrants to acquire shares of the
    Common Stock or securities exchangeable or exercisable for or convertible
    into shares of Common Stock (other than as contemplated by this Agreement
    with respect to the Common Shares); provided, however, that the Company may
    issue shares of its Common Stock or options to purchase its Common Stock
    pursuant to any of its currently existing stock option, stock bonus or other
    stock plans or arrangements, or Common Stock upon exercise of outstanding
    options or warrants.

        (k) Future Reports to the Representatives. During the period of two
    years hereafter the Company will furnish to BAS at 600 Montgomery Street,
    San Francisco, CA 94111, Attention: Mark Kuperschmid, as soon as available,
    copies of any report or communication of the Company mailed generally to
    holders of its capital stock.

        (l) Exchange Act Compliance. During the Prospectus Delivery Period, the
    Company will file all documents required to be filed with the Commission
    pursuant to Section 13, 14 or 15 of the Exchange Act in the manner and
    within the time periods required by the Exchange Act.

        BAS, on behalf of the several Underwriters, may, in its sole discretion,
waive in writing the performance by the Company of any one or more of the
foregoing covenants or extend the time for their performance.

   Section 4. Payment of Expenses. The Company agrees to pay all costs, fees and
expenses incurred in connection with the performance of its obligations
hereunder and in connection with the transactions contemplated hereby, including

any supplements thereto, advising the Underwriters of such qualifications,

    several Underwriters).

        (f) Officers' Certificate. On each of the First Closing Date and the
    Second Closing Date the Representatives shall have received a written
    certificate executed by the Chief Executive Officer of the Company and the
    Chief Financial Officer of the Company, dated as of such Closing Date, to
    the effect set forth in subsections (b)(ii) of this Section 5, and further
    to the effect that:

             (i) for the period from and after the date of this Agreement and
        prior to such Closing Date, there has not occurred any Material Adverse
        Change;

             (ii) the representations, warranties and covenants of the Company
        set forth in Section 1 of this Agreement are true and correct with the
        same force and effect as though expressly made on and as of such Closing
        Date; and

             (iii) the Company has complied with all the agreements hereunder
        and satisfied all the conditions on its part to be performed or
        satisfied hereunder at or prior to such Closing Date.

        (g) Bring-down Comfort Letter. On each of the First Closing Date and the
    Second Closing Date the Representatives shall have received from KPMG Peat
    Marwick LLP and McGladrey & Pullen LLP, independent public or certified
    public accountants for the Company, a letter dated such date, in form and
    substance satisfactory to the Representatives, to the effect that they
    reaffirm the statements made in the letter furnished by them pursuant to
    subsection (a) of this Section 5, except that the specified date referred to
    therein for the carrying out of procedures shall be no more than three
    business days prior to the First Closing Date or Second Closing Date, as the
    case may be (and the Representatives shall have received additional
    conformed copies of such accountants' letter for each of the several
    Underwriters).

        (h) Lock-Up Agreement from Certain Securityholders of the Company . On
    the date hereof, the Company shall have furnished to the Representatives an
    agreement in the form of Exhibit B hereto from the executive officers and
    directors and certain employees of the Company, and such agreement shall be
    in full force and effect on each of the First Closing Date and the Second
    Closing Date.

                                      -20-


             (i) Additional Documents. On or before each of the First Closing
        Date and the Second Closing Date, the Representatives and counsel for
        the Underwriters shall have received such information, documents and
        opinions as they may reasonably require for the purposes of enabling
        them to pass upon the issuance and sale of the Common Shares as
        contemplated herein, or in order to evidence the accuracy of any of the
        representations and warranties, or the satisfaction of any of the
        conditions or agreements, herein contained.

        If any condition specified in this Section 5 is not satisfied when and
as required to be satisfied, this Agreement may be terminated by the
Representatives by notice to the Company at any time on or prior to the First
Closing Date and, with respect to the Optional Common Shares, at any time prior
to the Second Closing Date, which termination shall be without liability on the
part of any party to any other party, except that Section 4, Section 6, Section
8 and Section  9 shall at all times be effective and shall survive such
termination.

   Section 6.  Reimbursement of Underwriters' Expenses.  If this Agreement is
terminated by the Representatives pursuant to Section 5 or Section 7, or if the
sale to the Underwriters of the Common Shares on the First Closing Date is not
consummated because of any refusal, inability or failure on the part of the
Company to perform any agreement herein or to comply with any provision hereof,
the Company agrees to reimburse the Representatives and the other Underwriters
(or such Underwriters as have terminated this Agreement with respect to
themselves), severally, upon demand for all out-of-pocket expenses that shall
have been reasonably incurred by the Representatives and the Underwriters in
connection with the proposed purchase and the offering and sale of the Common
Shares, including but not limited to fees and disbursements of counsel, printing
expenses, travel expenses, postage, facsimile and telephone charges.

   Section 7.  Effectiveness of this Agreement.

        This Agreement shall not become effective until the later of (i) the
execution of this Agreement by the parties hereto and (ii) notification by the
Commission to the Company and the Representatives of the effectiveness of the
Registration Statement under the Securities Act.

        Prior to such effectiveness, this Agreement may be terminated by any
party by notice to each of the other parties hereto, and any such termination
shall be without liability on the part (a) of the Company to any Underwriter,
except that the Company shall be obligated to reimburse the expenses of the
Representatives and the Underwriters pursuant to Sections 4 and 6 hereof, (b) of
any Underwriter to the Company, or (c) of any party hereto to any other party
except that the

                                      -21-


provisions of Section 8 and Section 9 shall at all times be effective and shall
survive such termination.

   Section 8.  Indemnification.

        (a) Indemnification of the Underwriters. The Company agrees to indemnify
    and hold harmless each Underwriter, its officers and employees, and each
    person, if any, who controls any Underwriter within the meaning of the
    Securities Act and the Exchange Act against any loss, claim, damage,
    liability or expense, as incurred, to which such Underwriter or such
    controlling person may become subject, under the Securities Act, the
    Exchange Act or other federal or state statutory law or regulation, or at
    common law or otherwise (including in settlement of any litigation, if such
    settlement is effected with the written consent of the Company), insofar as
    such loss, claim, damage, liability or expense (or actions in respect
    thereof as contemplated below) arises out of or is based (i) upon any untrue
    statement or alleged untrue statement of a material fact contained in the
    Registration Statement, or any amendment thereto, including any information
    deemed to be a part thereof pursuant to Rule 430A or Rule 434 under the
    Securities Act, or the omission or alleged omission therefrom of a material
    fact required to be stated therein or necessary to make the statements
    therein not misleading; or (ii) upon any untrue statement or alleged untrue
    statement of a material fact contained in any preliminary prospectus or the
    Prospectus (or any amendment or supplement thereto), or the omission or
    alleged omission therefrom of a material fact necessary in order to make the
    statements therein, in the light of the circumstances under which they were
    made, not misleading; or (iii) in whole or in part upon any inaccuracy in
    the representations and warranties of the Company contained herein; or (iv)
    in whole or in part upon any failure of the Company to perform its
    obligations hereunder or under law; and to reimburse each Underwriter and
    each such controlling person for any and all expenses (including the fees
    and disbursements of counsel chosen by BAS) as such expenses are reasonably
    incurred by such Underwriter or such controlling person in connection with
    investigating, defending, settling, compromising or paying any such loss,
    claim, damage, liability, expense or action; provided, however, that the
    foregoing indemnity agreement shall not apply to any loss, claim, damage,
    liability or expense to the extent, but only to the extent, arising out of
    or based upon any untrue statement or alleged untrue statement or omission
    or alleged omission made in reliance upon and in conformity with written
    information furnished to the Company by the Representatives expressly for
    use in the Registration Statement, any preliminary prospectus or the
    Prospectus (or any amendment or supplement thereto); and provided, further,

                                      -22-


    that with respect to any preliminary prospectus, the foregoing indemnity
    agreement shall not inure to the benefit of any Underwriter from whom the
    person asserting any loss, claim, damage, liability or expense purchased
    Common Shares, or any person controlling such Underwriter, if copies of the
    Prospectus were timely delivered to the Underwriter pursuant to Section 2
    and a copy of the Prospectus (as then amended or supplemented if the Company
    shall have furnished any amendments or supplements thereto) was not sent or
    given by or on behalf of such Underwriter to such person, if required by law
    so to have been delivered, at or prior to the written confirmation of the
    sale of the Common Shares to such person, and if the Prospectus (as so
    amended or supplemented) would have cured the defect giving rise to such
    loss, claim, damage, liability or expense. The indemnity agreement set forth
    in this Section 8(a) shall be in addition to any liabilities that the
    Company may otherwise have.

        (b) Indemnification of the Company, its Directors and Officers. Each
    Underwriter agrees, severally and not jointly, to indemnify and hold
    harmless the Company, each of its directors, each of its officers who signed
    the Registration Statement and each person, if any, who controls the Company
    within the meaning of the Securities Act or the Exchange Act, against any
    loss, claim, damage, liability or expense, as incurred, to which the
    Company, or any such director, officer or controlling person may become
    subject, under the Securities Act, the Exchange Act, or other federal or
    state statutory law or regulation, or at common law or otherwise (including
    in settlement of any litigation, if such settlement is effected with the
    written consent of such Underwriter), insofar as such loss, claim, damage,
    liability or expense (or actions in respect thereof as contemplated below)
    arises out of or is based upon any untrue or alleged untrue statement of a
    material fact contained in the Registration Statement, any preliminary
    prospectus or the Prospectus (or any amendment or supplement thereto), or
    arises out of or is based upon the omission or alleged omission to state
    therein a material fact required to be stated therein or necessary to make
    the statements therein not misleading, in each case to the extent, but only
    to the extent, that such untrue statement or alleged untrue statement or
    omission or alleged omission was made in the Registration Statement, any
    preliminary prospectus, the Prospectus (or any amendment or supplement
    thereto), in reliance upon and in conformity with written information
    furnished to the Company by the Representatives expressly for use therein;
    and to reimburse the Company, or any such director, officer or controlling
    person for any and all expenses (including the fees and disbursements of
    counsel chosen by the Company) as such expenses are reasonably incurred by
    the Company, or any such director, officer or controlling person in
    connection with investigating, defending,

                                      -23-


    settling, compromising or paying any such loss, claim, damage, liability,
    expense or action. The Company hereby acknowledges that the only information
    that the Underwriters have furnished to the Company expressly for use in the
    Registration Statement, any preliminary prospectus or the Prospectus (or any
    amendment or supplement thereto) are the statements set forth in the table
    in the first paragraph and the second, seventh, eighth, ninth, tenth,
    eleventh and twelfth paragraphs under the caption "Underwriting" in the
    Prospectus; and the Underwriters confirm that such statements are correct.
    The indemnity agreement set forth in this Section 8(b) shall be in addition
    to any liabilities that each Underwriter may otherwise have.

        (c) Notifications and Other Indemnification Procedures. Promptly after
    receipt by an indemnified party under this Section 8 of notice of the
    commencement of any action, such indemnified party will, if a claim in
    respect thereof is to be made against an indemnifying party under this
    Section 8, notify the indemnifying party in writing of the commencement
    thereof, but the omission so to notify the indemnifying party will not
    relieve it from any liability which it may have to any indemnified party for
    contribution or otherwise than under the indemnity agreement contained in
    this Section 8 or to the extent it is not prejudiced as a proximate result
    of such failure. In case any such action is brought against any indemnified
    party and such indemnified party seeks or intends to seek indemnity from an
    indemnifying party, the indemnifying party will be entitled to participate
    in, and, to the extent that it shall elect, jointly with all other
    indemnifying parties similarly notified, by written notice delivered to the
    indemnified party promptly after receiving the aforesaid notice from such
    indemnified party, to assume the defense thereof with counsel reasonably
    satisfactory to such indemnified party; provided, however, if the defendants
    in any such action include both the indemnified party and the indemnifying
    party and the indemnified party shall have reasonably concluded that a
    conflict may arise between the positions of the indemnifying party and the
    indemnified party in conducting the defense of any such action or that there
    may be legal defenses available to it and/or other indemnified parties which
    are different from or additional to those available to the indemnifying
    party, the indemnified party or parties shall have the right to select
    separate counsel to assume such legal defenses and to otherwise participate
    in the defense of such action on behalf of such indemnified party or
    parties. Upon receipt of notice from the indemnifying party to such
    indemnified party of such indemnifying party's election so to assume the
    defense of such action and approval by the indemnified party of counsel, the
    indemnifying party will not be liable to such indemnified party under this
    Section 8 for any legal or other expenses subsequently incurred by such
    indemnified party in connection with the

                                      -24-


    defense thereof unless (i) the indemnified party shall have employed
    separate counsel in accordance with the proviso to the next preceding
    sentence (it being understood, however, that the indemnifying party shall
    not be liable for the expenses of more than one separate counsel (together
    with local counsel), approved by the indemnifying party (BAS in the case of
    Section 8(b) and Section 9), representing the indemnified parties who are
    parties to such action) or (ii) the indemnifying party shall not have
    employed counsel satisfactory to the indemnified party to represent the
    indemnified party within a reasonable time after notice of commencement of
    the action, in each of which cases the fees and expenses of counsel shall be
    at the expense of the indemnifying party.

        (d) Settlements. The indemnifying party under this Section 8 shall not
    be liable for any settlement of any proceeding effected without its written
    consent, but if settled with such consent or if there be a final judgment
    for the plaintiff, the indemnifying party agrees to indemnify the
    indemnified party against any loss, claim, damage, liability or expense by
    reason of such settlement or judgment. Notwithstanding the foregoing
    sentence, if at any time an indemnified party shall have requested an
    indemnifying party to reimburse the indemnified party for fees and expenses
    of counsel as contemplated by Section 8(c) hereof, the indemnifying party
    agrees that it shall be liable for any settlement of any proceeding effected
    without its written consent if (i) such settlement is entered into more than
    30 days after receipt by such indemnifying party of the aforesaid request
    and (ii) such indemnifying party shall not have reimbursed the indemnified
    party in accordance with such request prior to the date of such settlement.
    No indemnifying party shall, without the prior written consent of the
    indemnified party, effect any settlement, compromise or consent to the entry
    of judgment in any pending or threatened action, suit or proceeding in
    respect of which any indemnified party is or could have been a party and
    indemnity was or could have been sought hereunder by such indemnified party,
    unless such settlement, compromise or consent includes an unconditional
    release of such indemnified party from all liability on claims that are the
    subject matter of such action, suit or proceeding.

   Section 9.  Contribution.

        If the indemnification provided for in Section 8 is for any reason held
to be unavailable to or otherwise insufficient to hold harmless an indemnified
party in respect of any losses, claims, damages, liabilities or expenses
referred to therein, then each indemnifying party shall contribute to the
aggregate amount paid or payable by such indemnified party, as incurred, as a
result of any losses,

                                      -25-


claims, damages, liabilities or expenses referred to therein (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company, on the one hand, and the Underwriters, on the other hand, from the
offering of the Common Shares pursuant to this Agreement or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company, on
the one hand, and the Underwriters, on the other hand, in connection with the
statements or omissions or inaccuracies in the representations and warranties
herein 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, on the one hand, and the Underwriters, on the other
hand, in connection with the offering of the Common Shares pursuant to this
Agreement shall be deemed to be in the same respective proportions as the total
net proceeds from the offering of the Common Shares pursuant to this Agreement
(before deducting expenses) received by the Company, and the total underwriting
discount received by the Underwriters, in each case as set forth on the front
cover page of the Prospectus (or, if Rule 434 under the Securities Act is used,
the corresponding location on the Term Sheet) bear to the aggregate public
offering price of the Common Shares as set forth on such cover. The relative
fault of the Company, on the one hand, and the Underwriters, on the other hand,
shall be determined by reference to, among other things, whether any such untrue
or alleged untrue statement of a material fact or omission or alleged omission
to state a material fact or any such inaccurate or alleged inaccurate
representation or warranty relates to information supplied by the Company, on
the one hand, or the Underwriters, on the other hand, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

        The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities and expenses referred to above shall be deemed to include,
subject to the limitations set forth in Section 8(c), any legal or other fees or
expenses reasonably incurred by such party in connection with investigating or
defending any action or claim.  The provisions set forth in Section 8(c) with
respect to notice of commencement of any action shall apply if a claim for
contribution is to be made under this Section 9; provided, however, that no
additional notice shall be required with respect to any action for which notice
has been given under Section 8(c) for purposes of indemnification.

        The Company 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 Underwriters were treated as one entity for such
purpose) or

                                      -26-


by any other method of allocation which does not take account of the equitable
considerations referred to in this Section 9.

        Notwithstanding the provisions of this Section 9, no Underwriter shall
be required to contribute any amount in excess of the underwriting commissions
received by such Underwriter in connection with the Common Shares underwritten
by it and distributed to the public.  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.  The Underwriters' obligations to contribute
pursuant to this Section 9 are several, and not joint, in proportion to their
respective underwriting commitments as set forth opposite their names in
Schedule A.  For purposes of this Section 9, each officer and employee of an
Underwriter and each person, if any, who controls an Underwriter within the
meaning of the Securities Act and the Exchange Act shall have the same rights to
contribution as such Underwriter, and each director of the Company, each officer
of the Company who signed the Registration Statement, and each person, if any,
who controls the Company with the meaning of the Securities Act and the Exchange
Act shall have the same rights to contribution as the Company.

   Section 10.  Default of One or More of the Several Underwriters.  If, on the
First Closing Date or the Second Closing Date, as the case may be, any one or
more of the several Underwriters shall fail or refuse to purchase Common Shares
that it or they have agreed to purchase hereunder on such date, and the
aggregate number of Common Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase does not exceed 10% of the
aggregate number of the Common Shares to be purchased on such date, the other
Underwriters shall be obligated, severally, in the proportions that the number
of Firm Common Shares set forth opposite their respective names on Schedule A
bears to the aggregate number of Firm Common Shares set forth opposite the names
of all such non-defaulting Underwriters, or in such other proportions as may be
specified by the Representatives with the consent of the non-defaulting
Underwriters, to purchase the Common Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date. If, on the
First Closing Date or the Second Closing Date, as the case may be, any one or
more of the Underwriters shall fail or refuse to purchase Common Shares and the
aggregate number of Common Shares with respect to which such default occurs
exceeds 10% of the aggregate number of Common Shares to be purchased on such
date, and arrangements satisfactory to the Representatives and the Company for
the purchase of such Common Shares are not made within 48 hours after such
default, this Agreement shall terminate without liability of any party to any
other party except that the provisions of Section 4, Section 6, Section 8 and
Section 9

                                      -27-


shall at all times be effective and shall survive such termination. In any such
case either the Representatives or the Company shall have the right to postpone
the First Closing Date or the Second Closing Date, as the case may be, but in no
event for longer than seven days in order that the required changes, if any, to
the Registration Statement and the Prospectus or any other documents or
arrangements may be effected.

        As used in this Agreement, the term "Underwriter" shall be deemed to
include any person substituted for a defaulting Underwriter under this Section
10.  Any action taken under this Section 10 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

   Section 11.  Termination of this Agreement.  Prior to the First Closing Date
this Agreement may be terminated by the Representatives by notice given to the
Company if at any time (i) trading or quotation in any of the Company's
securities shall have been suspended or limited by the Commission or by the
Nasdaq National Market or the Pacific Stock Exchange; (ii) trading in securities
generally on either the Nasdaq Stock Market or the New York Stock Exchange shall
have been suspended or limited, or minimum or maximum prices shall have been
generally established on any of such stock exchanges by the Commission or the
NASD; (iii) a general banking moratorium shall have been declared by any of
federal, New York or California authorities; (iv) there shall have occurred any
outbreak or escalation of national or international hostilities or any crisis or
calamity, or any change in the United States or international financial markets,
or any substantial change or development involving a prospective substantial
change in United States' or international political, financial or economic
conditions, as in the judgment of the Representatives is material and adverse
and makes it impracticable to market the Common Shares in the manner and on the
terms described in the Prospectus or to enforce contracts for the sale of
securities; (v) in the judgment of the Representatives there shall have occurred
any Material Adverse Change; or (vi) the Company shall have sustained a loss by
strike, fire, flood, earthquake, accident or other calamity of such character as
in the judgment of the Representatives may interfere materially with the conduct
of the business and operations of the Company regardless of whether or not such
loss shall have been insured.  Any termination pursuant to this Section 11 shall
be without liability on the part of (a) the Company to any Underwriter, except
that the Company shall be obligated to reimburse the expenses of the
Representatives and the Underwriters pursuant to Sections 4 and 6 hereof if this
Agreement is terminated as a result of clause (i), (v) or (vi) of this Section
11, (b)  any Underwriter to the Company, or (c) of any party hereto to any other
party except

                                      -28-


that the provisions of Section 8 and Section 9 shall at all times be effective
and shall survive such termination.

   Section 12.  Representations and Indemnities to Survive Delivery.  The
respective indemnities, agreements, representations, warranties and other
statements of the Company, of its officers and of the several Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter
or the Company or any of its or their partners, officers or directors or any
controlling person, as the case may be, and will survive delivery of and payment
for the Common Shares sold hereunder and any termination of this Agreement.

to Section 10 hereof, and to the benefit of the employees, officers and
directors and controlling persons referred to in Section 8 and Section 9, and in
each case their respective successors, and no other person will have any right

such purchase.

    party irrevocably submits to the exclusive jurisdiction (except for

    such court (a "Related Judgment"), as to which such jurisdiction is non-
    exclusive) of such courts in any such suit, action or proceeding. Service of

    irrevocably and unconditionally waive any objection to the laying of venue
    of any suit, action or other proceeding in the Specified Courts and
    irrevocably and unconditionally waive and agree not to plead or claim in any
    such court that any such suit, action or other proceeding brought in any
    such court has been brought in an inconvenient forum.

   Section 17.  General Provisions.  This Agreement constitutes the entire
agreement of the parties to this Agreement and supersedes all prior written or

respect to the subject matter hereof.  This Agreement may be executed in
two or more counterparts, each one of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
