registration statement as so amended (including any Rule 462(b) registration
statement). The term Prospectus as used in this Agreement shall mean the

       2.   Representations and Warranties of the Company and the Selling
Securityholder.


       (a)  The Company hereby represents and warrants as follows:

       (i)  Each of the Company and its subsidiaries has been duly incorporated
       and is validly existing as a corporation in good standing under the laws
       of the jurisdiction of its incorporation, has full corporate power and
       authority to own or lease its properties and conduct its business as
       described in the Registration Statement and the Prospectus and as being
       conducted, and is duly qualified as a foreign corporation and in good
       standing in all jurisdictions in which the character of the property
       owned or leased or the nature of the business transacted by it makes
       qualification necessary (except where the failure to be so qualified
       would not have a material adverse effect on the business, properties,
       financial condition or results of operations of the Company and its
       subsidiaries, taken as a whole).

       (ii)    Since the respective dates as of which information is given in
       the Registration Statement and the Prospectus, there has not been a
       Material Adverse Change (as defined below), other than as set forth in
       the Registration Statement and the Prospectus, and since such dates,
       except in the ordinary course of business, neither the Company nor any of
       its subsidiaries has entered into any material transaction not referred
       to in the Registration Statement and the Prospectus. As used herein,
       Material Adverse Change shall mean a materially adverse change in the
       business, properties, financial condition or results of operations of the
       Company and its subsidiaries, taken as a whole, whether or not arising
       from transactions in the ordinary course of business.

       (iii)    The Registration Statement and the Prospectus comply, and on the
       Closing Date (as hereinafter defined) and any later date on which Option
       Stock is to be purchased, the Prospectus will comply, in all material
       respects, with the provisions of the Securities Act and the rules and
       regulations of the Commission thereunder; on the Effective Date, the
       Registration Statement did not contain any untrue statement of a material
       fact and did not 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 Effective Date the Prospectus did not and, on the
       Closing Date and any later date on which Option Stock is to be purchased,
       will not contain any untrue statement of a material fact or omit 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; provided, however, that none of the representations and
       warranties in this subparagraph (iii) 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 or on behalf of the Underwriters
       for use in the Registration Statement or the Prospectus.

            Each of the Registration Statement and any Rule 462(b) registration
       statement has become effective under the Securities Act and no stop order
       suspending the effectiveness of the Registration Statement or any Rule
       462(b) registration statement has been issued under the Securities Act
       and no proceedings for that purpose have been instituted or are pending
       or, to the knowledge of the Company, are contemplated by the Commission,
       and


       any request on the part of the Commission for additional information has
       been complied with.

       (iv)    The Stock is duly and validly authorized, is (or, in the case of
       shares of the Stock to be sold by the Company, will be, when issued and
       sold to, and paid for by, the Underwriters as provided herein) duly and
       validly issued, fully paid and nonassessable and conforms to the
       description thereof in the Prospectus. No further approval or authority
       of the shareholders or the Board of Directors of the Company will be
       required for the transfer and sale of the Stock to be sold by the Selling
       Securityholder or the issuance and sale of the Stock as contemplated
       herein.

       (v)  Prior to the Closing Date the Stock to be issued and sold by the
       Company and the Stock to be sold by the Selling Securityholder will be
       authorized for listing by the Nasdaq National Market upon official notice
       of issuance.

       (vi)    Ernst & Young LLP, the accountants who certified the consolidated
       financial statements and supporting schedules included in the
       Registration Statement are independent public accountants as required by
       the Securities Act and the rules and regulations promulgated thereunder.

       (vii)    The consolidated financial statements included in the
       Registration Statement and the Prospectus, together with the related
       schedules and notes, present fairly, in all material respects, the
       financial position of the Company at the dates indicated and the results
       of its operations and its cash flows for the periods specified. Such
       consolidated financial statements have been prepared in conformity with
       generally accepted accounting principles (herein called GAAP) applied on
       a consistent basis throughout the periods involved. The supporting
       schedules included in the Registration Statement present fairly in
       accordance with GAAP the information required to be stated therein. The
       selected consolidated financial data and the summary consolidated
       financial data included in the Prospectus present fairly the information
       shown therein and have been compiled on a basis consistent with that of
       the audited consolidated financial statements included in the
       Registration Statement.

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


  securityholder of such subsidiary. The only subsidiaries of the Company are
  the subsidiaries listed on Exhibit 21 to the Registration Statement.

  (ix) The information set forth under the caption "Capitalization" in the
  Prospectus is true and correct in all material respects. All of the Stock
  conforms in all material respects to the description thereof contained in the
  Registration Statement. The form of certificates for the Stock conforms to the
  legal requirements of the State of Illinois.

  (x) This Agreement has been duly authorized, executed and delivered by the
  Company and is a valid and binding agreement of the Company, enforceable in
  accordance with its terms except insofar as indemnification and contribution
  provisions may be limited by applicable law or equitable principles and except
  as enforceability may be limited by bankruptcy, insolvency, reorganization,
  moratorium or similar laws relating to or affecting creditors' rights
  generally or by general equitable principles.

  (xi) Neither the Company nor any of its subsidiaries is in violation of its
  Articles of Incorporation or By-laws or in default in the performance or
  observance of any obligation, agreement, covenant or condition contained in
  any contract, indenture, mortgage, deed of trust, loan or credit agreement,
  note, lease or other agreement or instrument to which the Company or any of
  its subsidiaries is a party or by which it or any of them may be bound, or to
  which any of the property or assets of the Company or any subsidiary is
  subject (herein called the Agreements and Instruments) except for such
  defaults that would not result in a Material Adverse Change; and the
  execution, delivery and performance of this Agreement and the consummation of
  the transactions contemplated in this Agreement and in the Registration
  Statement (including the issuance and sale of the Stock and the use of the
  proceeds from the sale of the Stock as described in the Prospectus under the
  caption "Use of Proceeds") and compliance by the Company with its obligations
  under this Agreement have been duly authorized by all necessary corporate
  action and do not and will not, whether with or without the giving of notice
  or passage of time or both, conflict with or constitute a breach of, or
  default or, except as set forth in the Registration Statement, Repayment Event
  (as defined below) under, or result in the creation or imposition of any lien,
  charge or encumbrance upon any property or assets of the Company or any
  subsidiary pursuant to, the Agreements and Instruments (except for such
  conflicts, breaches or defaults or liens, charges or encumbrances that would
  not result in a Material Adverse Change), nor will such action result in any
  violation of the provisions of the charter or by-laws of the Company or any
  subsidiary or any applicable law, statute, rule, regulation, judgment, order,
  writ or decree of any government, government instrumentality or court,
  domestic or foreign, having jurisdiction over the Company or any subsidiary or
  any of their assets, properties or operations. As used herein, a Repayment
  Event means any event or condition which gives the holder of any note,
  debenture or other evidence of indebtedness (or any person acting on such
  holder's behalf) the right to require the repurchase, redemption or repayment
  of all or a portion of such indebtedness by the Company or any subsidiary.


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

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

  (xiv) There are no contracts or documents which are required to be described
  in the Registration Statement or the Prospectus or to be filed as exhibits
  thereto which have not been so described and filed as required.

  (xv) To its knowledge and except as described in the Registration Statement or
  the Prospectus, the Company together with its subsidiaries owns and possesses
  all right, title and interest in and to, or has duly licensed from third
  parties a valid, enforceable right to use, all patents, patent rights,
  licenses, inventions, copyrights, know-how (including trade secrets and other
  unpatented or unpatentable proprietary or confidential information, systems or
  procedures), trademarks, service marks and trade names (herein called Patent
  and Proprietary Rights) currently or proposed to be employed by it in
  connection with its business. Except as described in the Registration
  Statement or the Prospectus, neither the Company nor any of its subsidiaries
  has received any notice of or has any knowledge of any infringement or
  misappropriation of or conflict with asserted rights of others with respect to
  any Patent or Proprietary Rights, or of any facts which would render any
  Patent or Proprietary Rights invalid or inadequate to protect the interest of
  the Company or its subsidiaries therein, and which infringement,
  misappropriation or conflict or invalidity or inadequacy, individually or in
  the aggregate, would reasonably be expected to result in a Material Adverse
  Change.

  (xvi) No filing with, or authorization, approval, consent, license, order,
  registration, qualification or decree of, any court or governmental authority
  or agency is necessary or required for the performance by the Company of its
  obligations under this Agreement, in connection with the offering, issuance or
  sale of the Stock hereunder or the consummation of the transactions
  contemplated by this Agreement, except such as have


       been already obtained or as may be required under the Securities Act, or
       the rules and regulations promulgated thereunder, or state or foreign
       securities laws or pursuant to the regulations of the National
       Association of Securities Dealers, Inc. (the NASD).

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

       (xviii) Neither the Company nor its subsidiaries owns any real property.
       The Company and its subsidiaries have good and marketable title to all
       other properties and assets owned by them and reflected in the financial
       statements, in each case, free and clear of all mortgages, pledges,
       liens, security interests, claims, restrictions or encumbrances of any
       kind except such as (a) are described in the Prospectus (b) are reflected
       in the financial statements included in the Prospectus, or (c) do not,
       singly or in the aggregate, materially and adversely affect the value of
       such property and do not interfere with the use made and proposed to be
       made of such property by the Company or any of its subsidiaries; and all
       of the leases and subleases material to the business of the Company and
       its subsidiaries, considered as one enterprise, and under which the
       Company or any of its subsidiaries holds properties described in the
       Prospectus, are in full force and effect, and neither the Company nor any
       subsidiary has any notice of any material claim of any sort that has been
       asserted by anyone adverse to the rights of the Company or any subsidiary
       under any of the leases or subleases mentioned above, or affecting or
       questioning the rights of the Company or such subsidiary to the continued
       possession of the leased or subleased premises under any such lease or
       sublease.

       (xix) Except as described in the Registration Statement and except as
       would not, singly or in the aggregate, result in a Material Adverse
       Change, (A) neither the Company nor any of its subsidiaries is in
       violation of any federal, state, local or foreign statute, law, rule,
       regulation, ordinance, code, policy or rule of common law or any judicial
       or administrative interpretation thereof currently in effect, including
       any judicial or administrative order, consent decree or judgment,
       relating to pollution or protection of human health, 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 the release or threatened release of chemicals,
       pollutants, contaminants, wastes, toxic substances, hazardous substances,
       petroleum or petroleum products (herein called Hazardous Materials) or to
       the manufacture, processing, distribution, use, treatment, storage,
       disposal, transport or handling of Hazardous Materials (herein called
       Environmental Laws), (B) the Company and its subsidiaries have all
       permits, authorizations and approvals required under any applicable
       Environmental Laws and are each in compliance with their requirements,
       (C) there are no pending or, to the knowledge of the Company, threatened
       administrative, regulatory or judicial actions, suits, demands, demand
       letters, claims, liens, notices of noncompliance or violation,
       investigation or proceedings relating to any Environmental Law against
       the Company or any of its subsidiaries and (D) to the knowledge of the
       Company, there are no events or circumstances that might reasonably be
       expected to form the basis of an order for clean-up or remediation, or an
       action, suit or proceeding by any private party or governmental body or
       agency, against or affecting the Company or any of its subsidiaries
       relating to Hazardous Materials or any Environmental Laws.

       (xx) Except with respect to the registration rights of the holders of the
       Company's Series A Preferred Shares, Series B Preferred Shares and Series
       C Preferred Shares and the warrant holders as described in the
       Registration Statement, which registration rights have been waived by
       such holders, there are no persons with registration rights or other
       similar rights to have any securities registered pursuant to the

       federal, state, local and foreign income, payroll, franchise and other
       tax returns (after giving effect to extensions) and have paid all taxes
       shown as due thereon or with respect to any of its properties, and there
       is no tax deficiency that has been, or to the knowledge of the Company is
       likely to be, asserted against the Company, any of its subsidiaries or
       any of their properties or assets that would result in a Material Adverse
       Change.

       (xxii) The Company and each of its subsidiaries is insured by insurers of
       national recognition against such losses and risks and in such amounts as
       the Company believes is customary for companies engaged in the Company's
       business.

       (xxiii) The Company maintains a system of internal accounting controls
       sufficient to provide reasonable assurances that (A) transactions are
       executed in accordance with management's general or specific
       authorization; (B) transactions are recorded as necessary to permit
       preparation of financial statements in conformity with generally accepted
       accounting principles and to maintain accountability for assets; (C)

       any employee or agent of the Company has made any payment of funds of the
       Company or received or retained any funds in violation of any law, rule

       the country of manufacture, the importation of products into the United
       States, the exportation of products from the United States and the
       importation of products into another country and has provided all
       appropriate authorities with the requisite information, all of which, to
       the best of the Company's knowledge, is true and correct, necessary for
       the proper determination of the foregoing.

       published interpretations thereunder; no "reportable event" (as defined
       in ERISA and the regulations and published interpretations thereunder)
       has occurred with respect to any material "pension plan" (as defined in

       material respects and has received a favorable determination letter as to
       its qualification and nothing has occurred, whether by action or failure
       to act, which would cause the loss of such qualification. For purposes of
       this subsection, "Control Group" is defined to include any entity which
       is part of a group which includes the Company and is treated as a single
       employer under Section 414 of the Code.

       if applicable, is distributed by the Company in connection with the
       Directed Share Program.

       (xxx) No consent, approval, authorization or order of, or


       qualification with, any governmental body or agency, other than those
       already obtained, is required in connection with the offering of the
       Directed Shares in any jurisdiction where the Directed Shares are being
       offered by the Company.

       (xxxi) The Company has not offered, or caused Chase to offer, Stock to
       any person pursuant to the Directed Share Program with the intent to
       unlawfully influence (i) a customer or supplier of the Company to alter
       the customer's or supplier's level or type of business with the Company,
       or (ii) a trade journalist or publication to write or publish favorable
       information about the Company or its products.

       (b) The Selling Securityholder hereby represents and warrants as
follows:

       (i) The Registration Statement and the Prospectus comply, and on the
       Closing Date (as hereinafter defined) and any later date on which Option
       Stock is to be purchased, the Prospectus will comply, in all material
       respects, with the provisions of the Securities Act and the rules and
       regulations of the Commission thereunder; on the Effective Date, the
       Registration Statement did not contain any untrue statement of a material
       fact and did not 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 Effective Date the Prospectus did not and, on the
       Closing Date and any later date on which Option Stock is to be purchased,
       will not contain any untrue statement of a material fact or omit 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; provided, however, that none of the representations and
       warranties in this subparagraph (i) 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 or on behalf of the Underwriters
       for use in the Registration Statement or the Prospectus.

       (ii) Such Selling Securityholder has good and marketable title to all the
       shares of Stock to be sold by such Selling Securityholder hereunder, free
       and clear of all liens, encumbrances, equities, security interests and
       claims whatsoever, with full right and authority to deliver the same
       hereunder, subject, in the case of such Selling Securityholder, to the
       rights of [ ], as Custodian (herein called the Custodian), and that upon
       the delivery of and payment for such shares of the Stock hereunder, the
       several Underwriters will receive good and marketable title thereto, free
       and clear of all liens, encumbrances, equities, security interests and
       claims whatsoever.

       (iii) Certificates in negotiable form for the shares of the Stock to be
       sold by such Selling Securityholder have been placed in custody under a
       Custody Agreement for delivery under this Agreement with the Custodian;
       such Selling Securityholder specifically agrees that the shares of the
       Stock represented by the certificates so held in custody for such Selling
       Securityholder are subject to the interests of the several Underwriters
       and the Company, that the arrangements made by such Selling
       Securityholder


     for such custody, including the Power of Attorney provided for in such
     Custody Agreement, are to that extent irrevocable, and that the obligations
     of such Selling Securityholder shall not be terminated by any act of such
     Selling Securityholder or by operation of law, whether by the death or
     incapacity of such Selling Securityholder or the occurrence of any other
     event; if any such death, incapacity or other such event should occur
     before the delivery of such shares of the Stock hereunder, certificates for
     such shares of the Stock shall be delivered by the Custodian in accordance
     with the terms and conditions of this Agreement as if such death,
     incapacity or other event had not occurred, regardless of whether the
     Custodian shall have received notice of such death, incapacity or other
     event.

     3.   Purchase of the Stock by the Underwriters.

     (a)  On the basis of the representations and warranties and subject to
the terms and conditions herein set forth, the Company agrees to issue and sell
3,200,000 shares of the Underwritten Stock to the several Underwriters, and each
of the Underwriters agrees to purchase from the Company the respective aggregate
number of shares of Underwritten Stock set forth opposite its name in Schedule
I.  The price at which such shares of Underwritten Stock shall be sold by the
Company and purchased by the several Underwriters shall be $[          ] per
share.  The obligation of each Underwriter to the Company shall be to purchase
from the Company that number of shares of the Underwritten Stock which
represents the same proportion of the total number of shares of the Underwritten
Stock to be sold by the Company and pursuant to this Agreement as the number of
shares of the Underwritten Stock set forth opposite the name of such Underwriter
in Schedule I hereto represents of the total number of shares of the
Underwritten Stock to be purchased by all Underwriters pursuant to this
Agreement, as adjusted by you in such manner as you deem advisable to avoid
fractional shares.  In making this Agreement, each Underwriter is contracting
severally and not jointly; except as provided in paragraphs (b) and (c) of this
Section 3, the agreement of each Underwriter is to purchase only the respective
number of shares of the Underwritten Stock specified in Schedule I.

     (b)  If for any reason one or more of the Underwriters shall fail or
refuse (otherwise than for a reason sufficient to justify the termination of
this Agreement under the provisions of Section 8 or 9 hereof) to purchase and
pay for the number of shares of the Stock agreed to be purchased by such
Underwriter or Underwriters, the Company shall immediately give notice thereof
to you, and the non-defaulting Underwriters shall have the right within 24 hours
after the receipt by you of such notice to purchase, or procure one or more
other Underwriters to purchase, in such proportions as may be agreed upon
between you and such purchasing Underwriter or Underwriters and upon the terms
herein set forth, all or any part of the shares of the Stock which such
defaulting Underwriter or Underwriters agreed to purchase.  If the non-
defaulting Underwriters fail so to make such arrangements with respect to all
such shares, the number of shares of the Stock which each non-defaulting
Underwriter is otherwise obligated to purchase under this Agreement shall be
automatically increased on a pro rata basis to absorb the shares which the
defaulting Underwriter or Underwriters agreed to purchase; provided, however,
that the non-defaulting Underwriters shall not be


obligated to purchase the shares which the defaulting Underwriter or
Underwriters agreed to purchase if the aggregate number of such shares of the
Stock exceeds 10% of the total number of shares of the Stock which all
Underwriters agreed to purchase hereunder. If the total number of shares of the
Stock which the defaulting Underwriter or Underwriters agreed to purchase shall
not be purchased or absorbed in accordance with the two preceding sentences, the
Company shall have the right, within 24 hours next succeeding the 24-hour period
above referred to, to make arrangements with other underwriters or purchasers
satisfactory to you for purchase of such shares on the terms herein set forth.
In any such case, either you or the Company shall have the right to postpone the
Closing Date determined as provided in Section 5 hereof for not more than seven
business days after the date originally fixed as the Closing Date pursuant to
said Section 5 in order that any necessary changes in the Registration
Statement, the Prospectus or any other documents or arrangements may be made. If
neither the non-defaulting Underwriters nor the Company shall make arrangements
within the 24-hour periods stated above for the purchase of all the shares of
the Stock which the defaulting Underwriter or Underwriters agreed to purchase
hereunder, this Agreement shall be terminated without further act or deed and
without any liability on the part of the Company or the Selling Securityholder
to any non-defaulting Underwriter and without any liability on the part of any
non-defaulting Underwriter to the Company or the Selling Securityholder. Nothing
in this paragraph (b), and no action taken hereunder, shall relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

     (c)  On the basis of the representations, warranties and covenants herein
contained, and subject to the terms and conditions herein set forth, the Company
grants an option to the several Underwriters to purchase, severally and not
jointly, up to 240,000 shares in the aggregate of the Company Option Stock from
the Company at the same price per share as the Underwriters shall pay for the
Underwritten Stock, and the Selling Securityholder grants an option to the
several Underwriters to purchase, severally and not jointly, up to 240,000
shares in the aggregate of the Selling Securityholder Option Stock from the
Selling Securityholder at the same price per share as the Underwriters shall pay
for the Underwritten Stock.  Said option may be exercised only to cover over-
allotments in the sale of the Underwritten Stock by the Underwriters and may be
exercised in whole or in part at any time (but not more than once) on or before
the thirtieth day after the date of this Agreement upon written or telegraphic
notice by you to the Company setting forth the aggregate number of shares of the
Option Stock as to which the several Underwriters are exercising the option.  If
the underwriters exercise the option for less than all of the shares of Option
Stock, the Underwriters shall purchase from each of the Company and the Selling
Securityholder an equal number of shares of Option Stock.  Delivery of
certificates for the shares of Option Stock, and payment therefor, shall be made
as provided in Section 5 hereof.  The number of shares of the Option Stock to be
purchased by each Underwriter shall be the same percentage of the total number
of shares of the Option Stock to be purchased by the several Underwriters as
such Underwriter is purchasing of the Underwritten Stock, as adjusted by you in
such manner as you deem advisable to avoid fractional shares.


       4.   Offering by Underwriters.

       (a)  The terms of the initial public offering by the Underwriters of the
Stock to be purchased by them shall be as set forth in the Prospectus. The
Underwriters may from time to time change the public offering price after the
closing of the initial public offering and increase or decrease the concessions
and discounts to dealers as they may determine.

       (b)  The information set forth under "Underwriting" in the Registration
Statement, any Preliminary Prospectus and the Prospectus relating to the Stock
filed by the Company (insofar as such information relates to the Underwriters)
constitutes the only information furnished by the Underwriters to the Company
for inclusion in the Registration Statement, any Preliminary Prospectus, and the
Prospectus, and you on behalf of the respective Underwriters represent and
warrant to the Company that the statements made therein are correct.

       5.   Delivery of and Payment for the Stock.

       (a)  Delivery of certificates for the shares of the Underwritten Stock
and the Option Stock (if the option granted by Section 3(c) hereof shall have
been exercised not later than 7:00 a.m., San Francisco time, on the date two
business days preceding the Closing Date), and payment therefor, shall be made
at the office of McDermott, Will & Emery, 227 W. Monroe Street, Chicago,
Illinois 60606, at 8:00 a.m., Chicago time, on the fourth business day after the
date of this Agreement, or at such time on such other day, not later than seven
full business days after such fourth business day, as shall be agreed upon in
writing by the Company and you. The date and hour of such delivery and payment
(which may be postponed as provided in Section 3(b) hereof) are herein called
the Closing Date.

       (b)  If the option granted by Section 3(c) hereof shall be exercised
after 7:00 a.m., San Francisco time, on the date two business days preceding the
Closing Date, delivery of certificates for the shares of Option Stock, and
payment therefor, shall be made at the office of McDermott, Will & Emery, 227 W.
Monroe Street, Chicago, Illinois 60606, at 8:00 a.m., Chicago time, on the third
business day after the exercise of such option.

       (c)  Payment for the Stock purchased from the Company shall be made to
the Company or its order, and payment for any Stock purchased from the Selling
Securityholder shall be made to the Custodian, for the account of the Selling
Securityholder, in each case by one or more certified or official bank check or
checks in same day funds. Such payment shall be made upon delivery of
certificates for the Stock to you for the respective accounts of the several
Underwriters against receipt therefor signed by you. Certificates for the Stock
to be delivered to you shall be registered in such name or names and shall be in
such denominations as you may request at least one business day before the
Closing Date, in the case of Underwritten Stock, and at least one business day
prior to the purchase thereof, in the case of the Option Stock. Such
certificates will be made available to the Underwriters for inspection, checking
and packaging at the offices of Lewco Securities Corporation, 2 Broadway, New
York, New York 10004 on the business day prior to the Closing Date or, in the
case of the Option Stock, by 3:00 p.m., New York time, on the business day
preceding the date of purchase.

       It is understood that you, individually and not on behalf of the
Underwriters, may (but shall not be obligated to) make payment to the Company


and the Selling Securityholder for Stock to be purchased by any Underwriter
whose check shall not have been received by you on the Closing Date or any later
date on which Option Stock is purchased for the account of such Underwriter. Any
such payment by you shall not relieve such Underwriter from any of its
obligations hereunder.

       6.   Further Agreements of the Company and the Selling Securityholder.
Each of the Company and the Selling Securityholder respectively covenants and
agrees as follows:

       (a)  The Company will (i) prepare and timely file with the Commission
under Rule 424(b) a Prospectus containing information previously omitted at the
time of effectiveness of the Registration Statement in reliance on Rule 430A and
(ii) not file any amendment to the Registration Statement or supplement to the
Prospectus of which you shall not previously have been advised and furnished
with a copy or to which you shall have reasonably objected in writing or which
is not in compliance with the Securities Act or the rules and regulations of the
Commission.

       (b)  The Company will promptly notify each Underwriter in the event of
(i) the request by the Commission for amendment of the Registration Statement or
for supplement to the Prospectus or for any additional information, (ii) the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement, (iii) the institution or notice of intended institution
of any action or proceeding for that purpose, (iv) the receipt by the Company of
any notification with respect to the suspension of the qualification of the
Stock for sale in any jurisdiction, or (v) the receipt by it of notice of the
initiation or threatening of any proceeding for such purpose. The Company will
make every reasonable effort to prevent the issuance of such a stop order and,
if such an order shall at any time be issued, to obtain the withdrawal thereof
at the earliest possible moment.

       (c)  The Company will (i) on or before the Closing Date, deliver to you a
signed copy of the Registration Statement as originally filed and of each
amendment thereto filed prior to the time the Registration Statement becomes
effective and, promptly upon the filing thereof, a signed copy of each post-
effective amendment, if any, to the Registration Statement (together with, in
each case, all exhibits thereto unless previously furnished to you) and will
also deliver to you, for distribution to the Underwriters, a sufficient number
of additional conformed copies of each of the foregoing (but without exhibits)
so that one copy of each may be distributed to each Underwriter, (ii) as
promptly as possible deliver to you and send to the several Underwriters, at
such office or offices as you may designate, as many copies of the Prospectus as
you may reasonably request, and (iii) thereafter from time to time during the
period in which a prospectus is required by law to be delivered by an
Underwriter or dealer, likewise send to the Underwriters as many additional
copies of the Prospectus and as many copies of any supplement to the Prospectus
and of any amended prospectus, filed by the Company with the Commission, as you
may reasonably request for the purposes contemplated by the


Securities Act.

       (d)  If at any time during the period in which a prospectus is required
by law to be delivered by an Underwriter or dealer any event relating to or
affecting the Company, or of which the Company shall be advised in writing by
you, shall occur as a result of which it is necessary, in the opinion of counsel
for the Company or of counsel for the Underwriters, to supplement or amend the
Prospectus in order to make the Prospectus not misleading in the light of the
circumstances existing at the time it is delivered to a purchaser of the Stock,
the Company will forthwith prepare and file with the Commission a supplement to
the Prospectus or an amended prospectus so that the Prospectus as so
supplemented or amended will not contain any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements
therein, in the light of the circumstances existing at the time such Prospectus
is delivered to such purchaser, not misleading. If, after the initial public
offering of the Stock by the Underwriters and during such period, the
Underwriters shall propose to vary the terms of offering thereof by reason of
changes in general market conditions or otherwise, you will advise the Company
in writing of the proposed variation, and, if in the opinion either of counsel
for the Company or of counsel for the Underwriters such proposed variation
requires that the Prospectus be supplemented or amended, the Company will
forthwith prepare and file with the Commission a supplement to the Prospectus or
an amended prospectus setting forth such variation. The Company authorizes the
Underwriters and all dealers to whom any of the Stock may be sold by the several
Underwriters to use the Prospectus, as from time to time amended or
supplemented, in connection with the sale of the Stock in accordance with the
applicable provisions of the Securities Act and the applicable rules and
regulations thereunder for such period.

       (e)  Prior to the filing thereof with the Commission, the Company will
submit to you, for your information, a copy of any post-effective amendment to
the Registration Statement and any supplement to the Prospectus or any amended
prospectus proposed to be filed.

       (f)  The Company will cooperate, when and as requested by you, in the
qualification of the Stock for offer and sale under the securities or blue sky
laws of such jurisdictions as you may designate and, during the period in which
a prospectus is required by law to be delivered by an Underwriter or dealer, in
keeping such qualifications in good standing under said securities or blue sky
laws; provided, however, that the Company shall not be obligated to file any
general consent to service of process or to qualify as a foreign corporation in
any jurisdiction in which it is not so qualified. The Company will, from time to
time, prepare and file such statements, reports, and other documents as are or
may be required to continue such qualifications in effect for so long a period
as you may reasonably request for distribution of the Stock.

       (g)  During a period of five years commencing with the date hereof, the
Company will furnish to you, and to each Underwriter who may so request in
writing, copies of all periodic and special reports furnished to


shareholders of the Company and of all information, documents and reports filed
with the Commission.

       (h)  Not later than the 45th day following the end of the fiscal quarter
first occurring after the first anniversary of the Effective Date, the Company
will make generally available to its security holders an earnings statement in
accordance with Section 11(a) of the Securities Act and Rule 158 thereunder.

       (i)  The Company agrees to pay all costs and expenses incident to the
performance of its obligations under this Agreement, including all costs and
expenses incident to (i) the preparation, printing and filing with the
Commission and the National Association of Securities Dealers, Inc. (herein
called the NASD) of the Registration Statement, any Preliminary Prospectus and
the Prospectus, (ii) the furnishing to the Underwriters of copies of any
Preliminary Prospectus and of the several documents required by paragraph (c) of
this Section 6 to be so furnished, (iii) the printing of this Agreement and
related documents delivered to the Underwriters, (iv) the preparation, printing
and filing of all supplements and amendments to the Prospectus referred to in
paragraph (d) of this Section 6, (v) the furnishing to you and the Underwriters
of the reports and information referred to in paragraph (g) of this Section 6
and (vi) the printing and issuance of stock certificates, including the transfer
agent's fees. The Selling Securityholder will pay any transfer taxes incident to
the transfer to the Underwriters of the shares the Stock being sold by such
Selling Securityholder.

       (j)  The Company agrees to reimburse you, for the account of the several
Underwriters, for blue sky fees and related disbursements (including counsel
fees and disbursements and cost of printing memoranda for the Underwriters) paid
by or for the account of the Underwriters or their counsel in qualifying the
Stock under state securities or blue sky laws and in the review of the offering
by the NASD; provided, however, that such reimbursement shall not exceed $20,000
in the aggregate.

       (k)  The Company agrees to pay all fees and disbursements of counsel
incurred by the Underwriters in connection with the Directed Share Program and
stamp duties, similar taxes or duties or other taxes, if any, incurred by the
Underwriters in connection with the Directed Share Program.

       (l)  The provisions of paragraphs (i), (j) and (k) of this Section are
intended to relieve the Underwriters from the payment of the expenses and costs
which the Company and the Selling Securityholder hereby agree to pay and shall
not affect any agreement which the Company and the Selling Securityholder may
make, or may have made, for the sharing of any such expenses and costs.

       (m)  The Company and the Selling Securityholder hereby irrevocably agree
that neither the Company nor such Selling Securityholder, as the case may be,
will, directly or indirectly, sell, offer, contract to sell, sell any option,
right or warrant to purchase, transfer the economic risk or ownership in, make
any short sale, pledge, lend or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock, or any


       securities convertible into or exchangeable or exercisable for or any
       other rights to purchase or acquire Common Stock, without the prior
       written consent of Chase Securities Inc., acting alone, or of each of the
       Representatives of the Underwriters, acting jointly, for a period of 180
       days following the effective date of the Registration Statement. The
       foregoing sentence shall not apply to (A) the Stock to be sold to the
       Underwriters pursuant to this Agreement, (B) shares of Common Stock
       issued by the Company upon the exercise of options granted under the
       stock option plans and stock purchase plan of the Company (the "Option
       Plans") or upon the exercise of warrants outstanding as of the date
       hereof, all as described in "Capitalization" in the Preliminary
       Prospectus, and (C) options to purchase Common Stock granted under the
       Option Plans.

       (n) If at any time during the 25-day period after the Registration
       Statement becomes effective any rumor, publication or event relating to
       or affecting the Company shall occur as a result of which in your opinion
       the market price for the Stock has been or is likely to be materially
       affected (regardless of whether such rumor, publication or event
       necessitates a supplement to or amendment of the Prospectus), the Company
       will, after written notice from you advising the Company to the effect
       set forth above, forthwith prepare, consult with you concerning the
       substance of, and disseminate a press release or other public statement,
       reasonably satisfactory to you, responding to or commenting on such
       rumor, publication or event, unless in the opinion of counsel for the
       Company, the dissemination of such press release or other public
       statement would violate applicable securities laws.

       (o) The Company is familiar with the Investment Company Act of 1940, as
       amended, and has in the past conducted its affairs, and will in the
       future conduct its affairs, in such a manner to ensure that the Company
       was not and will not be an "investment company" or a company "controlled"
       by an "investment company" within the meaning of the Investment Company
       Act of 1940, as amended, and the rules and regulations thereunder.

       (p) The Company will place stop transfer orders on any Directed Shares
       that have been sold to Participants subject to the three month
       restriction on sale, transfer, assignment, pledge or hypothecation
       imposed by the NASD under its Interpretative Material 2110-1(d).

       (q) The Company will comply with all applicable securities and other
       applicable laws, rules and regulations in each jurisdiction in which the
       Directed Shares are offered in connection with the Directed Share
       Program.

       7.   Indemnification and Contribution.

       (a)  Subject to the provisions of paragraph (f) of this Section 7, the
Company and the Selling Securityholder jointly and severally agree to indemnify
and hold harmless each Underwriter and each person (including each partner or
officer thereof) who controls any Underwriter within the meaning of Section 15
of the Securities Act from and against any and all losses, claims, damages or
liabilities, joint or several, to which such indemnified parties or any of them
may become subject under the Securities Act, the Securities Exchange Act of
1934, as amended (herein called the Exchange Act), or the common law or
otherwise, and


the Company and the Selling Securityholder jointly and severally agree to
reimburse each such Underwriter and controlling person for any legal or other
expenses (including, except as otherwise hereinafter provided, reasonable fees
and disbursements of counsel) incurred by the respective indemnified parties in
connection with defending against any such losses, claims, damages or
liabilities or in connection with any investigation or inquiry of, or other
proceeding which may be brought against, the respective indemnified parties, in
each case arising out of or based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement
(including the Prospectus as part thereof and any Rule 462(b) registration
statement) or any post-effective amendment thereto (including any Rule 462(b)
registration statement), or 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, or (ii) any untrue statement or alleged untrue statement
of a material fact contained in any Preliminary Prospectus or the Prospectus (as
amended or as supplemented if the Company shall have filed with the Commission
any amendment thereof or supplement thereto) or the omission or alleged omission
to state therein a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; provided, however, that (1) the indemnity agreements of the Company
and the Selling Securityholder contained in this paragraph (a) shall not apply
to any such losses, claims, damages, liabilities or expenses if such statement
or omission was made in reliance upon and in conformity with information
furnished as herein stated or otherwise furnished in writing to the Company by
or on behalf of any Underwriter for use in any Preliminary Prospectus or the
Registration Statement or the Prospectus or any such amendment thereof or
supplement thereto, (2) the indemnity agreement contained in this paragraph (a)
with respect to any Preliminary Prospectus shall not inure to the benefit of any
Underwriter from whom the person asserting any such losses, claims, damages,
liabilities or expenses purchased the Stock which is the subject thereof (or to
the benefit of any person controlling such Underwriter) if at or prior to the
written confirmation of the sale of such Stock a copy of the Prospectus (or the
Prospectus as amended or supplemented) was not sent or delivered to such person
and the untrue statement or omission of a material fact contained in such
Preliminary Prospectus was corrected in the Prospectus (or the Prospectus as
amended or supplemented) unless the failure is the result of noncompliance by
the Company with paragraph (c) of Section 6 hereof, and (3) the Selling
Securityholder shall only be liable under this paragraph with respect to (A)
information pertaining to such Selling Securityholder furnished by or on behalf
of such Selling Securityholder expressly for use in any Preliminary Prospectus
or the Registration Statement or the Prospectus or any such amendment thereof or
supplement thereto or (B) facts that would constitute a breach of any
representation or warranty of such Selling Securityholder set forth in Section
2(b) hereof. The indemnity agreements of the Company and the Selling
Securityholder contained in this paragraph (a) and the representations and
warranties of the Company and the Selling Securityholder contained in Section 2
hereof shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any indemnified party and shall survive
the delivery of and payment for the Stock.


       (b)  Each Underwriter severally agrees to indemnify and hold harmless the
Company, each of its officers who signs the Registration Statement on his own
behalf or pursuant to a power of attorney, each of its directors, each other
Underwriter and each person (including each partner or officer thereof) who
controls the Company or any such other Underwriter within the meaning of Section
15 of the Securities Act, and the Selling Securityholder from and against any
and all losses, claims, damages or liabilities, joint or several, to which such
indemnified parties or any of them may become subject under the Securities Act,
the Exchange Act, or the common law or otherwise and to reimburse each of them
for any legal or other expenses (including, except as otherwise hereinafter
provided, reasonable fees and disbursements of counsel) incurred by the
respective indemnified parties in connection with defending against any such
losses, claims, damages or liabilities or in connection with any investigation
or inquiry of, or other proceeding which may be brought against, the respective
indemnified parties, in each case arising out of or based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (including the Prospectus as part thereof and any Rule
462(b) registration statement) or any post-effective amendment thereto
(including any Rule 462(b) registration statement) or 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 or (ii) any untrue
statement or alleged untrue statement of a material fact contained in the
Prospectus (as amended or as supplemented if the Company shall have filed with
the Commission any amendment thereof or supplement thereto) or the omission or
alleged omission to state therein a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, if such statement or omission was made in reliance upon
and in conformity with information furnished as herein stated or otherwise
furnished in writing to the Company by or on behalf of such indemnifying
Underwriter for use in the Registration Statement or the Prospectus or any such
amendment thereof or supplement thereto.  The indemnity agreement of each
Underwriter contained in this paragraph (b) shall remain operative and in full
force and effect regardless of any investigation made by or on behalf of any
indemnified party and shall survive the delivery of and payment for the Stock.

       (c)  Each party indemnified under the provisions of paragraphs (a) and
(b) of this Section 7 agrees that, upon the service of a summons or other
initial legal process upon it in any action or suit instituted against it or
upon its receipt of written notification of the commencement of any
investigation or inquiry of, or proceeding against, it in respect of which
indemnity may be sought on account of any indemnity agreement contained in such
paragraphs, it will promptly give written notice (herein called the Notice) of
such service or notification to the party or parties from whom indemnification
may be sought hereunder.  No indemnification provided for in such paragraphs
shall be available to any party who shall fail so to give the Notice if the
party to whom such Notice was not given was unaware of the action, suit,
investigation, inquiry or proceeding to which the Notice would have related and
was prejudiced by the failure to give the Notice, but the omission so to notify
such indemnifying party or parties of any such service or notification shall not
relieve such indemnifying party or parties


from any liability which it or they may have to the indemnified party for
contribution or otherwise than on account of such indemnity agreement, except as
specifically provided in paragraph (d) of this Section. Any indemnifying party
shall be entitled at its own expense to participate in the defense of any
action, suit or proceeding against, or investigation or inquiry of, an
indemnified party. Any indemnifying party shall be entitled, if it so elects
within a reasonable time after receipt of the Notice by giving written notice
(herein called the Notice of Defense) to the indemnified party, to assume (alone
or in conjunction with any other indemnifying party or parties) the entire
defense of such action, suit, investigation, inquiry or proceeding, in which
event such defense shall be conducted, at the expense of the indemnifying party
or parties, by counsel chosen by such indemnifying party or parties and
reasonably satisfactory to the indemnified party or parties; provided, however,
that (i) if the indemnified party or parties reasonably determine that there may
be a conflict between the positions of the indemnifying party or parties and of
the indemnified party or parties in conducting the defense of such action, suit,
investigation, inquiry or proceeding or that there may be legal defenses
available to such indemnified party or parties different from or in addition to
those available to the indemnifying party or parties, then counsel for the
indemnified party or parties shall be entitled to conduct the defense to the
extent reasonably determined by such counsel to be necessary to protect the
interests of the indemnified party or parties and (ii) in any event, the
indemnified party or parties shall be entitled to have counsel chosen by such
indemnified party or parties participate in, but not conduct, the defense. It is
understood that the indemnifying party shall not, in respect of the legal
expenses of any indemnified party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for all such
indemnified parties and that all such fees and expenses shall be reimbursed as
they are incurred. Such firm shall be designated in writing by Chase, in the
case of parties indemnified pursuant to paragraph (a) of this Section 7, and by
the Company, in the case of parties indemnified pursuant to paragraph (b) of
this Section 7. If, within a reasonable time after receipt of the Notice, an
indemnifying party gives a Notice of Defense and the counsel chosen by the
indemnifying party or parties is reasonably satisfactory to the indemnified
party or parties, the indemnifying party or parties will not be liable under
paragraphs (a) through (c) of this Section 7 for any legal or other expenses
subsequently incurred by the indemnified party or parties in connection with the
defense of the action, suit, investigation, inquiry or proceeding, except that
(A) the indemnifying party or parties shall bear the legal and other expenses
incurred in connection with the conduct of the defense as referred to in clause
(i) of the proviso to the preceding sentence and (B) the indemnifying party or
parties shall bear such other expenses as it or they have authorized to be
incurred by the indemnified party or parties. If, within a reasonable time after
receipt of the Notice, no Notice of Defense has been given, the indemnifying
party or parties shall be responsible for any legal or other expenses incurred
by the indemnified party or parties in connection with the defense of the
action, suit, investigation, inquiry or proceeding.

       (d)  If the indemnification provided for in this Section 7 is unavailable
or insufficient to hold harmless an indemnified party under paragraph (a) or (b)
of


this Section 7, then each indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of the losses, claims, damages or liabilities
referred to in paragraph (a) or (b) of this Section 7 (i) in such proportion as
is appropriate to reflect the relative benefits received by each indemnifying
party from the offering of the Stock 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 each indemnifying party in connection with
the statements or omissions that resulted in such losses, claims, damages or
liabilities, or actions in respect thereof, as well as any other relevant
equitable considerations.  The relative benefits received by the Company and the
Selling Securityholder on the one hand and the Underwriters on the other shall
be deemed to be in the same respective proportions as the total net proceeds
from the offering of the Stock received by the Company and the Selling
Securityholder and the total underwriting discount received by the Underwriters,
as set forth in the table on the cover page of the Prospectus, bear to the
aggregate public offering price of the Stock. Relative fault shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by each indemnifying party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission.

  The parties agree that it would not be just and equitable if contributions
pursuant to this paragraph (d) were to be determined by pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by any
other method of allocation which does not take into account the equitable
considerations referred to in the first sentence of this paragraph (d). The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities, or actions in respect thereof, referred to in the first sentence
of this paragraph (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigation,
preparing to defend or defending against any action or claim which is the
subject of this paragraph (d). Notwithstanding the provisions of this paragraph
(d), no Underwriter shall be required to contribute any amount in excess of the
underwriting discount applicable to the Stock purchased by such Underwriter. 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 in this paragraph (d) to contribute are several in proportion to
their respective underwriting obligations and not joint.

  Each party entitled to contribution agrees that upon the service of a summons
or other initial legal process upon it in any action instituted against it in
respect of which contribution may be sought, it will promptly give written
notice of such service to the party or parties from whom contribution may be
sought.  No contribution provided for hereunder shall be available to any party
who shall fail to give such written notice if the party to whom such notice was
not given was unaware of the legal proceeding to which the notice would have
related and was


prejudiced by the failure to give notice, but the omission so to notify such
party or parties of any such service shall not relieve such party or parties
from whom contribution may be sought from any liability which it or they may
have to each party entitled to contribution or otherwise (except as specifically
provided in paragraph (c) of this Section 7).

       (e)  Neither the Company nor the Selling Securityholder will, without the
prior written consent of each Underwriter, settle or compromise or consent to
the entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification may be sought hereunder (whether
or not such Underwriter or any person who controls such Underwriter within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act is
a party to such claim, action, suit or proceeding) unless such settlement,
compromise or consent includes an unconditional release of such Underwriter and
each such controlling person from all liability arising out of such claim,
action, suit or proceeding.

       (f)  The liability of the Selling Securityholder under such Selling
Securityholder's representations and warranties contained in paragraph (b) of
Section 2 hereof and under the indemnity and reimbursement agreements contained
in the provisions of this Section 7 and Section 12 hereof shall be limited to an
amount equal to the initial public offering price of the Stock sold by such
Selling Securityholder to the Underwriters.  The Company and the Selling
Securityholder may agree, as among themselves and without limiting the rights of
the Underwriters under this Agreement, as to the respective amounts of such
liability for which they each shall be responsible.

       8.   Directed Share Program Indemnification and Contribution.

       (a)  The Company agrees to indemnify and hold harmless Chase and each
person, if any, who controls Chase within the meaning of either Section 15 of
the Securities Act or Section 20 of the Exchange Act (herein called the Chase
Entities), from and against any and all losses, claims, damages or liabilities
(i) caused by any untrue statement or alleged untrue statement of a material
fact contained in any material prepared by or with the consent of the Company
for distribution to Participants in connection with the Directed Share Program,
or caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading; (ii) caused by the failure of any Participant to pay for and accept
delivery of Directed Shares that the Participant has agreed to purchase; or
(iii) related to, arising out of, or in connection with the Directed Share
Program, including those arising out of any violation or alleged violation of
the Act or out of any rescission right of any person in respect thereof, other
than losses, claims, damages or liabilities (or expenses relating thereto) that
are finally judicially determined to have resulted from the bad faith or gross
negligence of Chase Entities.

       (b)  Upon the service of a summons or other initial legal process upon
any Chase Entity in any action or suit instituted against it or upon its receipt
of written notification of the commencement of any investigation or inquiry of,
or proceeding against, it in respect of which indemnity may be sought pursuant
to


Section 8(a), the Chase Entity seeking indemnity will promptly give Notice of
such service or notification to the Company. No indemnification provided for in
Section 8(a) shall be available to any Chase Entity who shall fail so to give
the Notice to the Company if the Company was unaware of the action, suit,
investigation, inquiry or proceeding to which the Notice would have related and
was prejudiced by the failure to give the Notice, but the omission so to notify
the Company of any such service or notification shall not relieve the Company
from any liability shich it may have to any such Chase Entity for contribution
or otherwise than on account of such indemnity agreement in Section 8(a) (except
as specifically provided in paragraph (c) of this Section 8). Any Chase Entity
shall be entitled at its own expense to participate in the defense of any
action, suit or proceeding against, or investigation or inquiry of, such Chase
Entity. The Company shall be entitled, if it so elects within a reasonable time
after receipt of the Notice by giving a Notice of Defense to any such Chase
Entity, to assume the entire defense of such action, suit, investigation,
inquiry or proceeding, in which event such defense shall be conducted, at the
expense of the Company, by counsel chosen by the Company and reasonably
satisfactory to such Chase Entity; provided, however, that (i) if any such Chase
Entity reasonably determines that there may be a conflict between the positions
of the Company and of any such Chase Entity in conducting the defense of such
action, suit, investigation, inquiry or proceeding or that there may be legal
defenses available to such Chase Entity different from or in addition to those
available to the Company, then counsel for such Chase Entity shall be entitled
to conduct the defense to the extent reasonably determined by such counsel to be
necessary to protect the interests of such Chase Entity and (ii) in any event,
the Chase Entity shall be entitled to have counsel chosen by such Chase Entity
participate in, but not conduct, the defense. It is understood that the Company
shall not, in respect of the legal expenses of any such Chase Entity in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such Chase Entities and that all such fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated
in writing by such Chase Entity. If, within a reasonable time after receipt of
the Notice, the Company gives a Notice of Defense in connection with this
Section 8 and the counsel chosen by the Company is reasonably satisfactory to
the Chase Entity, the Company will not be liable under this Section 8 for any
legal or other expenses subsequently incurred by any such Chase Entity in
connection with the defense of the action, suit, investigation, inquiry or
proceeding, except that (A) the Company shall bear the legal and other expenses
incurred in connection with the conduct of the defense as referred to in clause
(i) of the proviso to the preceding sentence and (B) the Company shall bear such
other expenses as it or they have authorized to be incurred by any such Chase
Entity. If, within a reasonable time after receipt of the Notice, no Notice of
Defense has been given, the Company shall be responsible for any legal or other
expenses incurred by any such Chase Entity in connection with the defense of the
action, suit, investigation, inquiry or proceeding.

       (c) If the indemnification provided for in Section 8(a) is unavailable or
insufficient to hold harmless a Chase Entity under Section 8(a), then the
Company, in lieu of indemnifying the Chase Entity, shall contribute to the
amount


paid or payable by the Chase Entity as a result of the losses, claims, damages
or liabilities referred to in Section 8(a) (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Chase Entities on the other hand from the offering of the Directed
Shares or (ii) if the allocation provided by clause 8(c)(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 8(c)(i) above but also the
relative fault of the Company on the one hand and of the Chase Entities on the
other hand in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, or actions in respect thereof, as well
as any other relevant equitable considerations. The relative benefits received
by the Company on the one hand and of the Chase Entities on the other hand in
connection with the offering of the Directed Shares shall be deemed to be in the
same respective proportions as the total net proceeds from the offering of the
Directed Shares (before deducting expenses) and the total underwriting discounts
and commissions received by the Chase Entities for the Directed Shares, bear to
the aggregate public offering price of the Directed Shares. Relative fault of
the Company on the one hand and the Chase Entities on the other hand shall be
determined by reference to, among other things, whether the statement, act or
omission that resulted in losses, claims, damages or liabilities relates to
statements, acts or omissions by the Company or by the Chase Entities and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statements, acts or omissions.

       (d)  The Company and the Chase Entities agree that it would not be just
and equitable if contributions pursuant to this Section 8 were determined by pro
rata allocation (even if the Chase Entities were treated as one entity for such
purpose) or by any other method of allocation which does not take account the
equitable considerations referred to in Section 8(c).  The amount paid by the
Chase Entities as a result of the losses, claims, damages or liabilities, or
actions in respect thereof, referred to in the immediately preceding paragraph
shall be deemed to include any legal or other expenses reasonably incurred by
the Chase Entities in connection with investigating, preparing to defend or
defending against any action or claim which is the subject of Section 8(c).
Notwithstanding the provisions of this Section 8, no Chase Entity shall be
required to contribute any amount in excess of the underwriting discount
applicable to the Directed Shares 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.

  Each party entitled to contribution agrees that upon the service of a summons
or other initial legal process upon it in any action instituted against it in
respect of which contribution may be sought, it will promptly give written
notice of such service to the party or parties from whom contribution may be
sought.  No contribution provided for hereunder shall be available to any party
who shall fail to give such written notice if the party to whom such notice was
not given was unaware of the legal proceeding to which the notice would have
related and was prejudiced by the failure to give notice, but the omission so to
notify such party or parties of any such service shall not relieve such party or
parties from whom contribution may be sought from any liability which it or they
may have to each


party entitled to contribution or otherwise (except as specifically provided in
this Section 8).

       (e)  The indemnity and contribution provisions contained in this Section
8 shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
any Chase Entity or the Company, its officers or directors or any person
controlling the Company and (iii) acceptance of and payment for any of the
Directed Shares.

       9.   Termination.  This Agreement may be terminated by you at any time
prior to the Closing Date by giving written notice to the Company and the
Selling Securityholder if after the date of this Agreement trading in the Common
Stock shall have been suspended, or if there shall have occurred (a) the
engagement in hostilities or an escalation of major hostilities by the United
States or the declaration of war or a national emergency by the United States on
or after the date hereof, (b) any outbreak of hostilities or other national or
international calamity or crisis or change in economic or political conditions
if the effect of such outbreak, calamity, crisis or change in economic or
political conditions in the financial markets of the United States would, in the
Underwriters' reasonable judgment, make the offering or delivery of the Stock
impracticable, (c) suspension of trading in securities generally or a material
adverse decline in value of securities generally on the New York Stock Exchange,
the American Stock Exchange, or The Nasdaq Stock Market, or limitations on
prices (other than limitations on hours or numbers of days of trading) for
securities on either such exchange or system, (d) the enactment, publication,
decree or other promulgation of any federal or state statute, regulation, rule
or order of, or commencement of any proceeding or investigation by, any court,
legislative body, agency or other governmental authority which in the
Underwriters' reasonable opinion materially and adversely affects or will
materially or adversely affect the business or operations of the Company, (e)
declaration of a banking moratorium by either federal or New York State
authorities or (f) the taking of any action by any federal, state or local
government or agency in respect of its monetary or fiscal affairs which in the
Underwriters' reasonable opinion has a material adverse effect on the securities
markets in the United States.  If this Agreement shall be terminated pursuant to
this Section 9, there shall be no liability of the Company or the Selling
Securityholder to the Underwriters and no liability of the Underwriters to the
Company or the Selling Securityholder; provided, however, that in the event of
any such termination the Company and the Selling Securityholder agree to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the performance of the obligations of the Company and the Selling
Securityholder under this Agreement, including all costs and expenses referred
to in paragraphs (i), (j) and (k) of Section 6.

       10.   Conditions of Underwriters' Obligations.  The obligations of the
several Underwriters to purchase and pay for the Stock shall be subject to the
performance by the Company and by the Selling Securityholder of all their
respective obligations to be performed hereunder at or prior to the Closing Date
or any later date on which Option Stock is to be purchased, as the case may be,
and



to the following further conditions:

       (a) The Registration Statement shall have become effective; and no stop
       order suspending the effectiveness thereof shall have been issued and no
       proceedings therefor shall be pending or threatened by the Commission.

       (b) The legality and sufficiency of the sale of the Stock hereunder and
       the validity and form of the certificates representing the Stock, all
       corporate proceedings and other legal matters incident to the foregoing,
       and the form of the Registration Statement and of the Prospectus (except
       as to the financial statements contained therein), shall have been
       approved at or prior to the Closing Date by Davis Polk & Wardwell,
       counsel for the Underwriters.

       (c) You shall have received from McDermott, Will & Emery, counsel for the
       Company, Gordon & Glickson LLC, counsel for the Selling Securityholder,
       and from Crowell & Moring LLP, patent counsel for the Company, opinions,
       addressed to the Underwriters and dated the Closing Date, covering the
       matters set forth in Annex A-1, Annex A-2 and Annex B hereto,
       respectively, and if Option Stock is purchased at any date after the
       Closing Date, additional opinions from each such counsel, addressed to
       the Underwriters and dated such later date, confirming that the
       statements expressed as of the Closing Date in such opinions remain
       valid as of such later date.

       (d) You shall be satisfied that (i) as of the Effective Date, the
       statements made in the Registration Statement and the Prospectus were
       true and correct and neither the Registration Statement nor the
       Prospectus omitted to state any material fact required to be stated
       therein or necessary in order to make the statements therein,
       respectively, not misleading, (ii) since the Effective Date, no event has
       occurred which should have been set forth in a supplement or amendment to
       the Prospectus which has not been set forth in such a supplement or
       amendment, (iii) since the respective dates as of which information is
       given in the Registration Statement in the form in which it originally
       became effective and the Prospectus contained therein, there has not been
       any material adverse change or any development involving a prospective
       material adverse change in or affecting the business, properties,
       financial condition or results of operations of the Company, whether or
       not arising from transactions in the ordinary course of business, and,
       since such dates, except in the ordinary course of business, the Company
       has not entered into any material transaction not referred to in the
       Registration Statement in the form in which it originally became
       effective and the Prospectus contained therein, (iv) the Company does not
       have any material contingent obligations which are not disclosed in the
       Registration Statement and the Prospectus, (v) there are not any pending
       or known threatened legal proceedings to which the Company or any of its
       subsidiaries is a party or of which property of the Company or any of its
       subsidiaries is the subject which are material and which are not
       disclosed in the Registration Statement and the Prospectus, (vi) there
       are not any franchises, contracts, leases or other documents which are
       required to be filed as exhibits to the Registration Statement which have
       not been filed as required, (vii) the representations and warranties of
       the Company


       herein are true and correct in all material respects as of the Closing
       Date or any later date on which Option Stock is to be purchased, as the
       case may be, and (viii) there has not been any material change in the
       market for securities in general or in political, financial or economic
       conditions from those reasonably foreseeable as to render it
       impracticable in your reasonable judgment to make a public offering of
       the Stock, or a material adverse change in market levels for securities
       in general (or those of companies in particular) or financial or economic
       conditions which render it inadvisable in your reasonable judgment to
       proceed.

       (e) You shall have received on the Closing Date and on any later date on
       which Option Stock is purchased a certificate, dated the Closing Date or
       such later date, as the case may be, and signed by the President and the
       Chief Financial Officer of the Company, stating that the respective
       signers of said certificate have carefully examined the Registration
       Statement in the form in which it originally became effective and the
       Prospectus contained therein and any supplements or amendments thereto,
       and that the statements included in clauses (i) through (vii) of
       paragraph (d) of this Section 9 are true and correct.

       (f) You shall have received from Ernst & Young LLP, a letter or letters,
       addressed to the Underwriters and dated the Closing Date and any later
       date on which Option Stock is purchased, confirming that they are
       independent public accountants with respect to the Company within the
       meaning of the Securities Act and the applicable published rules and
       regulations thereunder and based upon the procedures described in their
       letter delivered to you concurrently with the execution of this Agreement
       (herein called the Original Letter), but carried out to a date not more
       than three business days prior to the Closing Date or such later date on
       which Option Stock is purchased (i) confirming, to the extent true, that
       the statements and conclusions set forth in the Original Letter are
       accurate as of the Closing Date or such later date, as the case may be,
       and (ii) setting forth any revisions and additions to the statements and
       conclusions set forth in the Original Letter which are necessary to
       reflect any changes in the facts described in the Original Letter since
       the date of the Original Letter or to reflect the availability of more
       recent financial statements, data or information. The letters shall not
       disclose any change, or any development involving a prospective change,
       in or affecting the business or properties of the Company which, in your
       sole judgment, makes it impractical or inadvisable to proceed with the
       public offering of the Stock or the purchase of the Option Stock as
       contemplated by the Prospectus.

       (g) You shall have received from Ernst & Young LLP a letter stating that
       their review of the Company's system of internal accounting controls, to
       the extent they deemed necessary in establishing the scope of their
       examination of the Company's financial statements as at [       , 2000],
       did not disclose any weakness in internal controls that they considered
       to be material weaknesses.

       (h) You shall have been furnished evidence in usual written or
       telegraphic form from the appropriate authorities of the several
       jurisdictions, or other evidence satisfactory to you, of the
       qualification


       referred to in paragraph (f) of Section 6 hereof.

       (i) Prior to the Closing Date, the Stock to be issued and sold by the
       Company shall have been duly authorized for listing by the Nasdaq
       National Market upon official notice of issuance.

       (j) On or prior to the Closing Date, you shall have received from all
       directors, officers, and beneficial holders of more than 1% of the
       outstanding Common Stock and all other securityholders of the Company
       agreements, in form reasonably satisfactory to Chase, stating that such
       party hereby irrevocably agrees that it will not, directly or indirectly,
       sell, offer, contract to sell, sell any option, right or warrant to
       purchase, transfer the economic risk or ownership in, make any short
       sale, pledge, lend or otherwise transfer or dispose of directly or
       indirectly, any shares of Common Stock, or any securities convertible
       into or exchangeable or exercisable for or any other rights to purchase
       or acquire Common Stock, without the prior written consent of Chase,
       acting alone, or of each of the Representatives of the Underwriters,
       acting jointly, for a period of 180 days following the effective date of
       the Registration Statement. The foregoing sentence shall not apply to (A)
       the Stock to be sold to the Underwriters pursuant to this Agreement, (B)
       shares of Common Stock issued by the Company upon the exercise of options
       granted under the stock option plans and stock purchase plan of the
       Company (the Option Plans) or upon the exercise of warrants outstanding
       as of the date hereof, all as described in the Preliminary Prospectus,
       and (C) options to purchase Common Stock granted under the Option Plans.

       All the agreements, opinions, certificates and letters mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if Davis Polk & Wardwell, counsel for the Underwriters,
shall be satisfied that they comply in form and scope.

       In case any of the conditions specified in this Section 10 shall not be
fulfilled, this Agreement may be terminated by you by giving notice to the
Company and to the Selling Securityholder.  Any such termination shall be
without liability of the Company or the Selling Securityholder to the
Underwriters and without liability of the Underwriters to the Company or the
Selling Securityholder; provided, however, that (i) in the event of such
termination, the Company and the Selling Securityholder agree to indemnify and
hold harmless the Underwriters from all costs or expenses incident to the
performance of the obligations of the Company and the Selling Securityholder
under this Agreement, including all costs and expenses referred to in paragraphs
(i), (j) and (k) of Section 6 hereof, and (ii) if this Agreement is terminated
by you because of any refusal, inability or failure on the part of the Company
or the Selling Securityholder to perform any agreement herein, to fulfill any of
the conditions herein, or to comply with any provision hereof other than by
reason of a default by any of the Underwriters, the Company will reimburse the
Underwriters severally upon demand for all out-of-pocket expenses (including
reasonable fees and disbursements of counsel) that shall have been incurred by
them in connection with the transactions contemplated hereby.


       11.   Conditions of the Obligation of the Company and the Selling
Securityholder.  The obligation of the Company and the Selling Securityholder to
deliver the Stock shall be subject to the conditions that (a) the Registration
Statement shall have become effective and (b) no stop order suspending the
effectiveness thereof shall be in effect and no proceedings therefor shall be
pending or threatened by the Commission.

       In case either of the conditions specified in this Section 11 shall not
be fulfilled, this Agreement may be terminated by the Company by giving notice
to you. Any such termination shall be without liability of the Company and the
Selling Securityholder to the Underwriters and without liability of the
Underwriters to the Company or the Selling Securityholder; provided, however,
that in the event of any such termination the Company and the Selling
Securityholder jointly and severally agree to indemnify and hold harmless the
Underwriters from all costs or expenses incident to the performance of the
obligations of the Company and the Selling Securityholder under this Agreement,
including all costs and expenses referred to in paragraphs (i), (j) and (k) of
Section 6 hereof.

       12.   Reimbursement of Certain Expenses.  In addition to their other
obligations under Sections 7 and 8 of this Agreement (and subject, in the case
of the Selling Securityholder, to the provisions of paragraph (f) of Section 7),
the Company and the Selling Securityholder hereby jointly and severally agree to
reimburse on a quarterly basis the Underwriters for all reasonable legal and
other expenses incurred in connection with investigating or defending any claim,
action, investigation, inquiry or other proceeding arising out of or based upon
any statement or omission, or any alleged statement or omission, described in
paragraph (a) of Sections 7 and 8 of this Agreement, notwithstanding the absence
of a judicial determination as to the propriety and enforceability of the
obligations under this Section 12 and the possibility that such payments might
later be held to be improper; provided, however, that (i) to the extent any such
payment is ultimately held to be improper, the persons receiving such payments
shall promptly refund them to the Company or the Selling Securityholder, as the
case may be, and (ii) such persons shall provide to the Company or the Selling
Securityholder, as the case may be, upon request, reasonable assurances of their
ability to effect any refund, when and if due.

       13.   Persons Entitled to Benefit of Agreement.  This Agreement shall

Underwriters and, with respect to the provisions of Sections 7 and 8 hereof, the
several parties (in addition to the Company, the Selling Securityholder and the
several Underwriters) indemnified under the provisions of said Sections 7 and 8,
and their respective personal representatives, successors and assigns.  Nothing
in this Agreement is intended or shall be construed to give to any other person,
firm or corporation any legal or equitable remedy or claim under or in respect
of this Agreement or any provision herein contained.  The term "successors and
assigns" as herein used shall not include any purchaser, as such purchaser, of
any of the Stock from any of the several Underwriters.

belief) at the Effective Date 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 (except as
to the financial statements and schedules and other financial data contained or
incorporated by reference therein, as to which such counsel need not express any

       (vi)  the information required to be set forth in the Registration
Statement in answer to Items 9, 10 (insofar as it relates to such counsel) and

known to such counsel which are listed on an attached schedule and which have
been identified to such counsel as all of the agreements and instruments which
are material to the business or financial condition of the Company or any of its

by the Company have waived such rights or such rights have expired by reason of
lapse of time following notification of the Company's intent to file the
Registration Statement;

       (xi)  no consent, approval, authorization or order of any court or
