ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 6 of Laser Vision's Certificate of Incorporation provides for
indemnification of the officers and directors of Laser Vision to the fullest
extent permitted by the laws of the State of Delaware.
 
     Section 145 of the General Corporation Law of the State of Delaware
provides generally and in pertinent part that a Delaware corporation may
indemnify its directors and officers against expenses, judgments, fines and
settlements actually and reasonably incurred by them in connection with any
civil suit or action, except actions by or in the right of the corporation, or
in connection with any administrative or investigative proceedings if, in
connection with the matters in issue, they acted in good faith and in a manner
they reasonable believed to be in, or not opposed to, the best interests of the
corporation and in connection with any criminal suit or proceeding, if in
connection with the matters in issue, they had no reasonably cause to believe
their conduct was unlawful. Section 145 further permits a Delaware corporation
to grant its directors and officers additional rights of indemnification through
bylaw provisions and otherwise and to purchase indemnity insurance on behalf of
its directors and officers.
 
     The Registrant maintains a policy of insurance under which the directors
and officers of the Registrant are insured, subject to the limits of the policy,
against certain losses arising from claims made against such directors and
officers by reason of any acts or omissions covered under such policy in their
respective capacities as directors or officers.

ITEM 17. UNDERTAKINGS
    
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act") may be permitted to directors,
officers and controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
Laser Vision hereby undertakes:
 
(1) To file, during any period in which offers or sales are being made, a
Post-Effective Amendment to this registration statement:
 
     (i) To include any prospectus required by section 10(a) of the Securities
     Act;
 
     (ii) To reflect in the prospectus any facts or events arising after the
     Effective Date of the registration statement (or the most recent
     Post-Effective Amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement;
 
     (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement;
 
provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 (the
"Exchange Act") that are incorporated by reference in the registration
statement.
 
(2) That, for the purpose of determining liability under the Securities Act,
each Post-Effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
                                      II-2
<PAGE>   4
 
(3) To remove from registration by means of a Post-Effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.
 
(4) That, for purposes of determining any liability under the Securities Act,
the information omitted from the form of prospectus filed as part of the
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
(5) That for purposes of determining any liability under the Securities Act,
each filing of the Registrant's annual report pursuant to section 13(a) or
section 15(d) of the Exchange Act (and where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the Exchange
Act) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
(6) That for the purposes of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

     c/o A.G. Edwards & Sons, Inc.
     One North Jefferson Avenue
     St. Louis, Missouri 63103

         The undersigned, Laser Vision Centers, Inc., a Delaware corporation
(the "Company"), and the persons listed on Schedule I hereto (the "Selling
Shareholders"), hereby address you as the representatives (the
"Representatives") of each of the persons, firms and corporations listed on
Schedule II hereto (collectively, the "Underwriters") and hereby confirm their
agreement with the several Underwriters as follows:

         1. DESCRIPTION OF SHARES. The Company proposes to issue and sell to the
Underwriters one million (1,000,000) shares of its Common Stock, par value $ .01
per share, and the Selling Shareholders propose to sell to the Underwriters a
total of Seven Hundred Twenty Thousand (720,000) shares of the Company's Common
Stock, par value $ .01 per share, as set forth on Schedule I hereto (such
1,720,000 shares of Common Stock are herein collectively referred to as the
"Firm Shares"). Solely for the purpose of covering over-allotments in the sale
of the Firm Shares, certain of the Selling Shareholders set forth on Schedule
III hereto (the "Option Shareholders") further propose to grant to the
Underwriters the right to purchase up to an additional 258,000 shares of Common
Stock (the "Option Shares"), as provided in Section 3 of this Agreement. The
Firm Shares and the Option Shares are herein sometimes referred to as the
"Shares" and are more fully described in the Prospectus hereinafter defined.

         2. PURCHASE, SALE AND DELIVERY OF FIRM SHARES. On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company agrees to sell to the
Underwriters under the terms hereof One Million (1,000,000) shares of its common
stock and each Selling Shareholder agrees, severally and not jointly, to sell to
the Underwriters the number of Firm Shares set forth opposite the name of such
Selling Shareholder on Schedule I hereto, and each such Underwriter agrees,
severally and not jointly, (a) to purchase from the Company and from each of the
Selling Shareholders, pro rata, at a purchase price of $___ per share, the
number of Firm Shares set forth


<PAGE>   2


opposite the name of such Underwriter on Schedule II hereto and (b) to purchase
from the Option Shareholders any additional number of Option Shares which such
Underwriter may become obligated to purchase pursuant to Section 3 hereof.


         The Company and the Selling Shareholders will deliver definitive
certificates (for purposes herein, "definitive certificates" will include any
electronic format equivalent reasonably acceptable to the Representatives) for 
the Firm Shares at the office of A.G. Edwards & Sons, Inc., One North Jefferson
Avenue, St. Louis, Missouri 63103 ("Edwards' Office"), or such other place as
you and the Company may mutually agree upon, for the accounts of the
Underwriters against payment to the Company and the Selling Shareholders of the
purchase price for the Firm Shares sold by them to the several Underwriters by
wire transfer of immediately available funds payable to the order of the Company
and the Selling Shareholders, as their respective interests may appear, and
delivered to One North Jefferson Avenue, St. Louis, Missouri 63103, or at such
other place as may be agreed upon between you and the Company (the "Place of
Closing"), at 10:00 a.m., St. Louis time, on ____________, 1999, or at such
other time and date not later than five full business days thereafter as you and
the Company may agree, such time and date of payment and delivery being herein

         The certificates for the Firm Shares so to be delivered will be made
available to you for inspection at Edwards' Office (or such other place as you
and the Company may mutually agree upon) at least one full business day prior to
the Closing Date and will be in such names and denominations as you may request
at least forty-eight hours prior to the Closing Date.

         It is understood that an Underwriter, individually, may (but shall not
be obligated to) make payment on behalf of the other Underwriters whose funds
shall not have been received prior to the Closing Date for Shares to be
purchased by such Underwriter. Any such payment by an Underwriter shall not
relieve the other Underwriters of any of their obligations hereunder.

         It is understood that the Underwriters propose to offer the Shares to
the public upon the terms and conditions set forth in the Registration Statement
hereinafter defined.

         3. PURCHASE, SALE AND DELIVERY OF THE OPTION SHARES. The Option
Shareholders hereby grant options to the Underwriters to purchase from them, on
a pro rata basis, up to Two Hundred Fifty-Eight Thousand (258,000) Option
Shares, respectively, on the same terms and conditions as the Firm Shares;
provided, however, that such options may be exercised only for the purpose of
covering any over-allotments which may be made by them in the sale of the Firm
Shares. No Option Shares shall be sold or delivered unless the Firm Shares
previously have been, or simultaneously are, sold and delivered. Each Option
Shareholder shall sell up to that number of Option Shares set forth opposite the
name of such Option Shareholder on Schedule III hereto.

         The options are exercisable on behalf of the several Underwriters by
you, as Representatives, at any time, and from time to time, before the
expiration of 30 days from the date of the Prospectus (or, if such 30th day
shall be a Saturday or Sunday or a holiday, on the next day thereunder when the
Nasdaq National Market is open for trading), for the purchase of all or part of
the Option Shares covered thereby, by notice given by you to the Option
Shareholders in the


 

                                       2
<PAGE>   3


manner provided in Section 13 hereof, setting forth the number of Option Shares
as to which the Underwriters are exercising the options, and the date of
delivery of said Option Shares, which date shall not be more than five business
days after such notice unless otherwise agreed to by the parties. You may
terminate the options at any time, as to any unexercised portion thereof, by
giving written notice to the Option Shareholders to such effect.

         You, as Representatives, shall make such allocation of the Option
Shares among the Underwriters as may be required to eliminate purchases of
fractional Shares.

         Delivery of the Option Shares with respect to which the options shall
have been exercised shall be made to or upon your order at Edwards' Office (or
at such other place as you and the Company may mutually agree upon), against
payment by you of the per share purchase price to the Option Shareholders by
wire transfer of immediately available funds. Such payment and delivery shall be
made at 10:00 a.m., St. Louis time, on the date designated in the notice given
by you as above provided for (which may be the same as the Closing Date), unless
some other date and time are agreed upon, which date and time of payment and
delivery are called the "Option Closing Date." The certificates for the Option
Shares so to be delivered will be made available to you for inspection at
Edwards' Office at least one full business day prior to the Option Closing Date
and will be in such names and denominations as you may request at least
forty-eight hours prior to the Option Closing Date. On the Option Closing Date,
the Option Shareholders and the Company shall provide the Underwriters such
representations, warranties, agreements, opinions, letters, certificates and
covenants with respect to the Option Shares as are required to be delivered on
the Closing Date with respect to the Firm Shares.

         4. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY AND THE
SELLING SHAREHOLDERS. (a) The Company and the Selling Shareholders set forth on
Schedule IV hereto (the "Principal Selling Shareholders") jointly and severally
represent and warrant to and agree with each Underwriter that:

                  (i) A registration statement (Registration No. 333-72941) on
         Form S-3 with respect to the Shares, including a preliminary
         prospectus, and such amendments to such registration statement as may
         have been required to the date of this Agreement, has been carefully
         prepared by the Company pursuant to and in conformity with the
         requirements of the Securities Act of 1933, as amended (the "1933
         Act"), and the rules and regulations thereunder (the "1933 Act Rules
         and Regulations") of the Securities and Exchange Commission (the "SEC")
         and has been filed with the SEC under the 1933 Act. The Company meets
         the requirements for use of Form S-3 under the 1933 Act. Copies of such
         registration statement, including any amendments thereto, each related
         preliminary prospectus (meeting the requirements of Rule 430 or 430A of
         the 1933 Act Rules and Regulations) contained therein, and the
         exhibits, financial statements and schedules thereto have heretofore
         been delivered by the Company to you. If such registration statement
         has not become effective under the 1933 Act, a further amendment to
         such registration statement, including a form of final prospectus,
         necessary to permit such





                                       3
<PAGE>   4


         registration statement to become effective will be filed promptly by
         the Company with the SEC. If such registration statement has become
         effective under the 1933 Act, a final prospectus containing information
         permitted to be omitted at the time of effectiveness by Rule 430A of
         the 1933 Act Rules and Regulations will be filed promptly by the
         Company with the SEC in accordance with Rule 424(b) of the 1933 Act
         Rules and Regulations. The term "Registration Statement" as used herein
         means the registration statement as amended at the time it becomes
         effective under the 1933 Act (the "Effective Date"), including
         financial statements and all exhibits and all documents incorporated by
         reference therein pursuant to Item 12 of Form S-3 under the 1933 Act
         and, if applicable, the information deemed to be included by Rule 430A
         of the 1933 Act Rules and Regulations. If it is contemplated, at the
         time this Agreement is executed, that a post-effective amendment to
         such registration statement will be filed and must be declared
         effective before the offering of Shares may commence, the term
         "Registration Statement" as used herein means the registration
         statement as amended by said post-effective amendment. If an
         abbreviated registration statement is prepared and filed with the SEC
         in accordance with Rule 462(b) under the 1933 Act (an "Abbreviated
         Registration Statement"), the term "Registration Statement" as used in
         this Agreement includes the Abbreviated Registration Statement. The
         term "Prospectus" as used herein means (i) the prospectus as first
         filed with the SEC pursuant to Rule 424(b) of the 1933 Act Rules and
         Regulations, or (ii) if no such filing is required, the form of final
         prospectus included in the Registration Statement at the Effective
         Date, or (iii) if a Term Sheet or Abbreviated Term Sheet (as such terms
         are defined in Rule 434(b) and 434(c), respectively, of the 1933 Act
         Rules and Regulations) is filed with the SEC pursuant to Rule 424(b)(7)
         of the 1933 Act Rules and Regulations, the Term Sheet or Abbreviated
         Term Sheet and the last Preliminary Prospectus filed with the SEC prior
         to the time the Registration Statement became effective, taken
         together, including, in each case, the documents incorporated by
         reference therein pursuant to Item 12 of Form S-3 under the 1933 Act.
         The term "Preliminary Prospectus" as used herein shall mean a
         preliminary prospectus as contemplated by Rule 430 or 430A of the 1933
         Act Rules and Regulations included at any time in the Registration
         Statement. For purposes of this Agreement, the words "amend,"
         "amendment," "amended," "supplement" or "supplemented" with respect to
         the Registration Statement or the Prospectus shall mean amendments or
         supplements to the Registration Statement or the Prospectus, as the
         case may be, as well as documents filed after the date of this
         Agreement and prior to the completion of the distribution of the Shares
         and incorporated by reference therein as described above.

                  (ii) Neither the SEC nor any state or other jurisdiction or
         other regulatory body has issued, and neither is, to the knowledge of
         the Company, threatening to issue, any stop order under the 1933 Act or
         other order suspending the effectiveness of the Registration Statement
         (as amended or supplemented) or preventing or suspending the use of any
         Preliminary Prospectus or the Prospectus or suspending the
         qualification or registration of the Shares for offering or sale in any
         jurisdiction nor instituted or, to the knowledge of the Company,
         threatened to institute proceedings for any such purpose.



                                       4

         Each Preliminary Prospectus at its date of issue, the Registration
         Statement and the Prospectus and any amendments or supplements thereto
         contain or will contain, as the case may be, all statements which are
         required to be stated therein by, and in all material respects conform
         or will conform, as the case may be, to the requirements of, the 1933
         Act and the 1933 Act Rules and Regulations. Neither the Registration
         Statement nor any amendment thereto, as of the applicable effective
         date, contains or will contain, as the case may be, any untrue
         statement of a material fact or omits or will omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein, not misleading, and neither any Preliminary
         Prospectus, the Prospectus nor any supplement thereto contains or will
         contain, as the case may be, any untrue statement of a material fact or
         omits or will omit to state any material fact required to be stated
         therein or necessary to make the statements therein, in the light of
         the circumstances under which they were made, not misleading; provided,
         however, that the Company makes no representation or warranty as to
         information contained in or omitted from the Registration Statement or
         the Prospectus, or any such amendment or supplement, in reliance upon,
         and in conformity with, written information furnished to the Company
         relating to the Underwriters by or on behalf of the Underwriters
         expressly for use in the preparation thereof (as provided in Section 14
         hereof). There is no contract or document required to be described in
         the Registration Statement or Prospectus or to be filed as an exhibit
         to the Registration Statement which is not described or filed as
         required. The documents incorporated by reference in the Prospectus
         pursuant to Item 12 of Form S-3 under the 1933 Act, at the time they
         were filed with the SEC, complied in all material respects with the
         requirements of the Securities Exchange Act of 1934, as amended (the
         "1934 Act"), and the rules and regulations adopted by the SEC
         thereunder (the "1934 Act Rules and Regulations"). Any future documents
         incorporated by reference so filed, when they are filed, will comply in
         all material respects with the requirements of the 1934 Act and the
         1934 Act Rules and Regulations; no such incorporated document contained
         or will contain any untrue statement of a material fact or omit to
         state a material fact required to be stated therein or necessary to
         make the statements therein not misleading; and, when read together and
         with the other information in the Prospectus, at the time the
         Registration Statement became effective and at the Closing Date, each
         such incorporated document did not or will not, as the case may be,
         contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading.

                  (iii) This Agreement has been duly authorized, executed and
         delivered by the Company and constitutes a valid and legally binding
         obligation of the Company enforceable against the Company in accordance
         with its terms, except as enforceability may be limited by bankruptcy,
         insolvency, fraudulent conveyance, reorganization, moratorium and other
         similar laws relating to or affecting creditors' rights generally and
         by general principles of equity (the "Exceptions").

                  (iv) The Company and its subsidiaries have been duly organized
         and are validly existing as corporations in good standing under the
         laws of the states or other jurisdictions in which they are
         incorporated, with full power and authority (corporate and other) to
         own, lease and operate their properties and conduct their businesses as
         described in the Prospectus and, with respect to the Company, to
         execute and deliver, and perform the Company's obligations under, this
         Agreement; the Company and its subsidiaries are duly qualified to do
         business as foreign corporations in good standing in each state or
         other jurisdiction in which their ownership or leasing of property or
         conduct of business legally requires such qualification, except where
         the failure to be so qualified, individually or in the aggregate, would
         not have a Material Adverse Effect. The term "Material Adverse Effect"
         as used herein means any material adverse effect on the condition
         (financial or other), net worth, business, affairs, management,
         prospects, results of operations or cash flow of the Company and its
         subsidiaries, taken as a whole.

                  (v) Neither the Company nor any of its subsidiaries has
         sustained since the date of the latest audited financial statements
         included or incorporated by reference in the Prospectus any material
         loss or interference with its business from fire, explosion, flood or
         other calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree. Otherwise
         than as set forth in the Prospectus and, since the respective dates as
         of which information is given in the Prospectus, there has not been any
         change in the capital stock or long-term debt of the Company or any of
         its subsidiaries or any material adverse change, or any development
         involving a prospective material adverse change, in or affecting the
         general affairs, management, financial position, stockholders' equity
         or results of operations of the Company and its subsidiaries taken as a
         whole, otherwise than as set forth in the Prospectus.

                  (vi) The issuance and sale of the Shares and the execution,
         delivery and performance by the Company of this Agreement, and the
         consummation of the transactions herein contemplated, will not conflict
         with or result in a breach or violation of any of the terms or
         provisions of, or constitute a default under, or result in the creation
         or imposition of any lien, charge or encumbrance upon any properties or
         assets of the Company or any of its subsidiaries under, any indenture,
         mortgage, deed of trust, loan agreement or other agreement or
         instrument to which the Company or any of its subsidiaries is a party
         or by which the Company or any of its subsidiaries is bound or to which
         any of the properties or assets of the Company or any of its
         subsidiaries is subject, except to such extent as, individually or in
         the aggregate, does not have a Material Adverse Effect, nor will such
         action result in any violation of the provisions of the Company's
         certificate of incorporation or bylaws or any statute, rule, regulation
         or other law, or any order or judgment, of any court or governmental
         agency or body having jurisdiction over the Company or any of its
         subsidiaries or any of their properties; and no consent, approval,
         authorization, order, registration or qualification of or with any such
         court or governmental agency or body is required for the execution,
         delivery and performance of this Agreement, the issuance and sale of
         the Shares or the consummation 





                                       6
<PAGE>   7


         of the transactions contemplated hereby, except such as have been, or
         will be prior to the Closing Date, obtained under the 1933 Act or as
         may be required by the National Association of Securities Dealers, Inc.
         (the "NASD") and such consents, approvals, authorizations,
         registrations or qualifications as may be required under state
         securities or blue sky laws in connection with the purchase and
         distribution of the Shares by the Underwriters.

                  (vii) The Company has duly and validly authorized capital
         stock as set forth in the Prospectus; all outstanding shares of Common
         Stock of the Company and the Shares conform, or when issued will
         conform, to the description thereof in the Prospectus and have been,
         or, when issued and paid for in the manner described herein will be,
         duly authorized, validly issued, fully paid and non-assessable; and the
         issuance of the Shares to be purchased from the Company hereunder is
         not subject to preemptive or other similar rights, or any restriction
         upon the voting or transfer thereof pursuant to applicable law or the
         Company's certificate of incorporation, by-laws or governing documents
         or any agreement to which the Company or any of its subsidiaries is a
         party or by which any of them may be bound. All corporate action
         required to be taken by the Company for the authorization, issuance and
         sale of the Shares has been duly and validly taken. Except as disclosed
         in the Prospectus, there are no outstanding subscriptions, rights,
         warrants, options, calls, convertible securities, commitments of sale
         or rights related to or entitling any person to purchase or otherwise
         to acquire any shares of, or any security convertible into or
         exchangeable or exercisable for, the capital stock of, or other
         ownership interest in, the Company. The outstanding shares of capital
         stock of the Company's subsidiaries have been duly authorized and
         validly issued, are fully paid and non-assessable and are owned by the
         Company free and clear of any mortgage, pledge, lien, encumbrance,
         charge or adverse claim and are not the subject of any agreement or
         understanding with any person and were not issued in violation of any
         preemptive or similar rights; and there are no outstanding
         subscriptions, rights, warrants, options, calls, convertible
         securities, commitments of sale or instruments related to or entitling
         any person to purchase or otherwise acquire any shares of, or any
         security convertible into or exchangeable or exercisable for, the
         capital stock of, or other ownership interest in any of the
         subsidiaries.

                  (viii) The statements set forth in the Prospectus describing
         the Shares, certain regulatory matters affecting the Company and this
         Agreement, insofar as they purport to describe the provisions of the
         laws and documents referred to therein, are accurate, complete and
         fair.

                  (ix) Each of the Company and its subsidiaries is in possession
         of and is operating in compliance with all franchises, grants,
         authorizations, licenses, certificates, permits, easements, consents,
         orders and approvals ("Permits") from all state, federal, foreign and
         other regulatory authorities, and has satisfied the requirements
         imposed by regulatory bodies, administrative agencies or other
         governmental bodies, agencies or officials, that are required for the
         Company and its subsidiaries lawfully to own, lease and




                                       7
<PAGE>   8


         operate their properties and conduct their businesses as described in
         the Prospectus, and, each of the Company and its subsidiaries is
         conducting its business in compliance with all of the laws, rules and
         regulations of each jurisdiction in which it conducts its business, in
         each case with such exceptions, individually or in the aggregate, as
         would not have a Material Adverse Effect; each of the Company and its
         subsidiaries has filed all notices, reports, documents or other
         information ("Notices") required to be filed under applicable laws,
         rules and regulations, in each case, with such exceptions, individually
         or in the aggregate, as would not have a Material Adverse Effect; and,
         except as otherwise specifically described in the Prospectus, neither
         the Company nor any of its subsidiaries has received any notification
         from any court or governmental body, authority or agency, relating to
         the revocation or modification of any such Permit or, to the effect
         that any additional authorization, approval, order, consent, license,
         certificate, permit, registration or qualification ("Approvals") from
         such regulatory authority is needed to be obtained by any of them, in
         any case where it could be reasonably expected that obtaining such
         Approvals or the failure to obtain such Approvals, individually or in
         the aggregate, would have a Material Adverse Effect.

                  (x) The Company and its subsidiaries have filed all necessary
         federal, state and foreign income and franchise tax returns and paid
         all taxes shown as due thereon; all such tax returns are complete and
         correct in all material respects; all tax liabilities are adequately
         provided for on the books of the Company and its subsidiaries except to
         such extent as would not have a Material Adverse Effect; the Company
         and its subsidiaries have made all necessary payroll tax payments and
         are current and up-to-date; and the Company and its subsidiaries have
         no knowledge of any tax proceeding or action pending or threatened
         against the Company or its subsidiaries which, individually or in the
         aggregate, might have a Material Adverse Effect.

                  (xi) Except as described in the Prospectus, the Company and
         its subsidiaries own or possess, or can acquire on reasonable terms,
         adequate patents, patent licenses, trademarks, service marks and trade
         names necessary to conduct the business now operated by them, and
         neither the Company nor any of its subsidiaries has received any notice
         of infringement of or conflict with asserted rights of others with
         respect to any patents, patent licenses, trademarks, service marks or
         trade names which, individually or in the aggregate, if the subject of
         an unfavorable decision, ruling or finding, would have a Material
         Adverse Effect.

                  (xii) The Company and its subsidiaries have good and
         marketable title in fee simple to all items of real property and good
         and marketable title to all personal property owned by them, in each
         case free and clear of all liens, encumbrances, restrictions and
         defects except such as are described in the Prospectus or do not
         materially affect the value of such property and do not interfere with
         the use made and proposed to be made of such property; and any property
         held under lease or sublease by the Company or any of its subsidiaries
         is held under valid, subsisting and enforceable leases or subleases
         with such




                                       8
<PAGE>   9


         exceptions as are not material and do not interfere with the use made
         and proposed to be made of such property by the Company and its
         subsidiaries; and neither the Company nor any of its subsidiaries has
         any notice or knowledge of any material claim of any sort which has
         been, or may be, asserted by anyone adverse to the Company's or any of
         its subsidiaries rights as lessee or sublessee under any lease or
         sublease described above, or affecting or questioning the Company's or
         any of its subsidiaries' rights to the continued possession of the
         leased or subleased premises under any such lease or sublease in
         conflict with the terms thereof.

                  (xiii) Except as described in the Prospectus, there is no
         factual basis for any action, suit or other proceeding involving the
         Company or any of its subsidiaries or any of their material assets for
         any failure of the Company or any of its subsidiaries, or any
         predecessor thereof, to comply with any requirements of federal, state
         or local regulation relating to air, water, solid waste management,
         hazardous or toxic substances, or the protection of health or the
         environment. Except as described in the Prospectus, none of the
         property owned or leased by the Company or any of its subsidiaries is
         contaminated with any waste or hazardous substances, and neither the
         Company nor any of its subsidiaries may be deemed an "owner or
         operator" of a "facility" or "vessel" which owns, possesses,
         transports, generates or disposes of a "hazardous substance" as those
         terms are defined in ss.9601 of the Comprehensive Environmental
         Response, Compensation and Liability Act of 1980, 42 U.S.C. ss.9601 et
         seq.

                  (xiv) No labor disturbance exists with the employees of the
         Company or any of its subsidiaries or is imminent which, individually
         or in the aggregate, would have a Material Adverse Effect. None of the
         employees of the Company or any of its subsidiaries is represented by a
         union and, to the best knowledge of the Company and its subsidiaries,
         no union organizing activities are taking place. Neither the Company
         nor any of its subsidiaries has violated any federal, state or local
         law or foreign law relating to discrimination in hiring, promotion or
         pay of employees, nor any applicable wage or hour laws, or the rules
         and regulations thereunder, or analogous foreign laws and regulations,
         which might, individually or in the aggregate, result in a Material
         Adverse Effect.

                  (xv) The Company and its subsidiaries are in compliance in all
         material respects with all presently applicable provisions of the
         Employee Retirement Income Security Act of 1974, as amended, including
         the regulations and published interpretations thereunder ("ERISA"); no
         "reportable event" (as defined in ERISA) has occurred with respect to
         any "pension plan" (as defined in ERISA) for which the Company and its
         subsidiaries would have any liability; the Company and its subsidiaries
         have not incurred and do not expect to incur liability under (i) Title
         IV of ERISA with respect to termination of, or withdrawal from, any
         "pension plan" or (ii) Sections 412 or 4971 of the Internal Revenue
         Code of 1986, as amended, including the regulations and published
         interpretations thereunder (the "Code"); and each "pension plan" for
         which the Company or any of its subsidiaries would have any liability
         that is intended to be qualified under 



                                       9
<PAGE>   10


         Section 401(a) of the Code is so qualified in all material respects,
         and nothing has occurred, whether by action or by failure to act, which
         would cause the loss of such qualification.

                  (xvi) The Company and its subsidiaries maintain insurance of
         the types and in the amounts generally deemed adequate for its
         business, including, but not limited to, directors' and officers'
         insurance, insurance covering real and personal property owned or
         leased by the Company and its subsidiaries against theft, damage,
         destruction, acts of vandalism and all other risks customarily insured
         against, all of which insurance is in full force and effect. Neither
         the Company nor any of its subsidiaries has been refused any insurance
         coverage sought or applied for, and the Company has no reason to
         believe that it and its subsidiaries will not be able to renew their
         existing insurance coverage as and when such coverage expires or to
         obtain similar coverage from similar insurers as may be necessary to
         continue its business at a cost that would not have a Material Adverse
         Effect.

                  (xvii) Neither the Company nor any of its subsidiaries is, or
         with the giving of notice or lapse of time or both would be, in default
         or violation with respect to its certificate of incorporation or
         by-laws. Neither the Company nor any of its subsidiaries is, or with
         the giving of notice or lapse of time or both would be, in default in
         the performance or observance of any material obligation, agreement,
         covenant or condition contained in any indenture, mortgage, deed of
         trust, loan agreement, lease or other agreement or instrument to which
         the Company or any of its subsidiaries is a party or by which the
         Company or any of its subsidiaries is bound or to which any of the
         properties or assets of the Company or any of its subsidiaries is
         subject, or in violation of any statutes, laws, ordinances or
         governmental rules or regulations or any orders or decrees to which it
         is subject, including, without limitation, Section 13 of the 1934 Act,
         which default or violation, individually or in the aggregate, would
         have a Material Adverse Effect. Neither the Company nor any of its
         subsidiaries has, at any time during the past five years, (A) made any
         unlawful contributions to any candidate for any political office, or
         failed fully to disclose any contribution in violation of law, or (B)
         made any payment to any state, federal or foreign government official,
         or other person charged with similar public or quasi-public duty (other
         than payment required or permitted by applicable law).

                  (xviii) Other than as set forth in the Prospectus, there are
         no legal or governmental proceedings pending to which the Company or
         any of its subsidiaries is a party or of which any property of the
         Company or any of its subsidiaries is the subject that, if determined
         adversely to the Company or any of its subsidiaries, would individually
         or in the aggregate have a Material Adverse Effect or which would
         materially and adversely affect the consummation of the transactions
         contemplated hereby or which is required to be disclosed in the
         Prospectus; to the best of the Company's knowledge, no such proceedings
         are threatened or contemplated.

                  (xix) The Company is not and, after giving effect to the
         offering and sale of the Shares, will not be a "holding company," or a
         "subsidiary company" of a "holding company," or an "affiliate" of a
         "holding company" or of a "subsidiary company," as such terms are
         defined in the Public Utility Holding Company Act of 1935, as amended
         (the "1935 Act").

                  (xx) The Company is not and, after giving effect to the
         offering and sale of the Shares, will not be an "investment company" or
         an entity "controlled" by an "investment company," as such terms are
         defined in the Investment Company Act of 1940, as amended (the "1940
         Act").

                  (xxi) PricewaterhouseCoopers LLP, the accounting firm which
         has certified the financial statements filed with or incorporated by
         reference in and as a part of the Registration Statement, is an
         independent public accounting firm within the meaning of the 1933 Act
         and the 1933 Act Rules and Regulations. The Company and each of its
         subsidiaries maintains a system of internal accounting controls
         sufficient to provide reasonable assurance that: (1) transactions are
         executed in accordance with management's general or specific
         authorizations; (2) transactions are recorded as necessary to permit
         preparation of financial statements in conformity with generally
         accepted accounting principles and to maintain accountability for
         assets; (3) access to assets is permitted only in accordance with
         management's general or specific authorization; and (4) the recorded
         accounts for assets is compared with the existing assets at reasonable
         intervals and appropriate action is taken with respect thereto. The
         consolidated financial statements and schedules of the Company,
         including the notes thereto, filed with (or incorporated by reference)
         and as a part of the Registration Statement or Prospectus, are accurate
         in all material respects and present fairly the financial condition of
         the Company and its subsidiaries as of the respective dates thereof and
         the consolidated results of operations and changes in financial
         position and consolidated statements of cash flow for the respective
         periods covered thereby, all in conformity with generally accepted
         accounting principles applied on a consistent basis throughout the
         periods involved except as otherwise disclosed therein. All adjustments
         necessary for a fair presentation of results for such periods have been
         made. The selected financial data included or incorporated by reference
         in the Registration Statement and Prospectus present fairly the
         information shown therein and have been compiled on a basis consistent
         with that of the audited financial statements. Any operating or other
         statistical data included or incorporated by reference in the
         Registration Statement and Prospectus comply in all material respects
         with the 1933 Act and the 1933 Act Rules and Regulations and present
         fairly the information shown therein.

                  (xxii) Except as disclosed in the Prospectus, no holder of any
         security of the Company has any right to require registration of shares
         of Common Stock or any other security of the Company because of the
         filing of the Registration Statement or the consummation of the
         transactions contemplated hereby, and, except as disclosed in the




                                       11
<PAGE>   12


         Prospectus, no person has the right to require registration under the
         1933 Act of any shares of Common Stock or other securities of the
         Company. No person has the right, contractual or otherwise, to cause
         the Company to permit such person to underwrite the sale of any of the
         Shares. Except for this Agreement, there are no contracts, agreements
         or understandings between the Company or any of its subsidiaries and
         any person that would give rise to a valid claim against the Company,
         its subsidiaries or any Underwriter for a brokerage commission,
         finder's fee or like payment in connection with the issuance, purchase
         and sale of the Shares.

                  (xxiii) The Company has not distributed and, prior to the
         later to occur of (i) the Closing Date or the Option Closing Date, if
         any, and (ii) completion of the distribution of the Shares, will not
         distribute any offering material in connection with the offering and
         sale of the Shares other than the Registration Statement, the
         Preliminary Prospectus or the Prospectus.

                  (xxiv) The Company has not taken and will not take, directly
         or indirectly, any action designed to or which might reasonably be
         expected to cause or result in stabilization or manipulation of the
         price of the Company's Common Stock, and the Company is not aware of
         any such action taken or to be taken by affiliates of the Company.

         (b) Each Selling Shareholder severally represents and warrants to and
agrees with each Underwriter and the Company that:

                  (i) All consents, approvals, authorizations and orders
         necessary for the execution and delivery by it of this Agreement, and
         the Custody Agreement and Power of Attorney (as defined herein) and the
         sale and delivery of the Shares to be sold by such Selling Shareholder
         hereunder and thereunder have been given and are in full force and
         effect on the date hereof and will be in full force and effect on the
         Closing Date (and, if applicable, the Option Closing Date). This
         Agreement and the Custody Agreement and Power of Attorney have been
         duly authorized, executed and delivered by or on behalf of such Selling
         Shareholder and are the valid and legally binding obligations of such
         Selling Shareholder enforceable in accordance with their terms except
         as enforceability may be limited by the Exceptions and except to the
         extent the enforceability of the indemnification and contribution
         provisions hereof and thereof may be limited by public policy
         considerations as expressed in the 1933 Act as construed by courts of
         competent jurisdiction.

                  (ii) Such Selling Shareholder has, and on the Closing Date
         (and, if applicable, the Option Closing Date) will have, good, valid
         and marketable title to the Shares to be sold by such Selling
         Shareholder, free and clear of all liens, mortgages, pledges,
         encumbrances, claims, equities and security interests whatsoever,
         including any restriction on transfer other than pursuant to this
         Agreement and the Custody Agreement



                                       12
<PAGE>   13


         and Power of Attorney referred to herein, and now has, and on the
         Closing Date (and, if applicable, the Option Closing Date), will have,
         full right, power and authority, and any approval required by law, to
         enter into this Agreement and the Custody Agreement and Power of
         Attorney and to sell, assign, transfer and deliver the Shares to be
         sold by such Selling Shareholder hereunder.

                  (iii) Upon delivery of and payment for such Shares hereunder,
         the several Underwriters will acquire good, valid and marketable title
         to such Shares to be sold by such Selling Shareholder hereunder, free
         and clear of all liens, mortgages, pledges, encumbrances, claims,
         equities and security interests whatsoever.

                  (iv) The execution, delivery and performance of this Agreement
         and the Custody Agreement and Power of Attorney by such Selling
         Shareholder, and the consummation by such Selling Shareholder of the
         transactions contemplated herein and therein will not conflict with or
         result in a breach or violation of any the terms or provisions of, or
         constitute a default under, or result in the creation or imposition of
         any lien, charge or encumbrance upon any of the properties or assets of
         such Selling Shareholder under, any indenture, mortgage, deed of trust,
         loan agreement or other agreement or instrument to which such Selling
         Shareholder is a party or by which it is bound or to which any of the
         properties or assets of such Selling Shareholder is subject (or any
         certificate or articles of incorporation or bylaws, partnership
         agreement, trust document or articles of association of such Selling
         Shareholder, as applicable), or any order or decree, or statute, law,
         ordinance, rule or regulation applicable to such Selling Shareholder of
         any court or of any governmental agency, authority or body having
         jurisdiction over such Selling Shareholder or its properties or assets.

                  (v) Such Selling Shareholder does not have any knowledge or
         any reason to believe that the Registration Statement or the Prospectus
         (or any amendment or supplement thereto) contains any untrue statement
         of a material fact or omits to state any material fact required to be
         stated therein or necessary to make the statements therein not
         misleading. The representations and warranties of such Selling
         Shareholder in the Custody Agreement and Power of Attorney are, and on
         the Closing Date and any Option Closing Date will be, true and correct.

                  (vi) Such Selling Shareholder has not taken and will not take,
         directly or indirectly, any action designed to or which might be
         reasonably expected to cause or result in stabilization or manipulation
         of the price of the Common Stock, and such Selling Shareholder is not
         aware of any such action taken or to be taken by affiliates of such
         Selling Shareholder.

                  (vii) When the Registration Statement becomes effective and at
         all times subsequent thereto, such information in the Registration
         Statement and Prospectus and any amendments or supplements thereto as
         specifically relates to such Selling




                                       13
<PAGE>   14


         Shareholder will not contain any untrue statement of a material fact or
         omit to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading.

                  (viii) Certificates in negotiable form representing all of the
         Shares to be sold by such Selling Shareholder hereunder have been
         placed in the custody of ____________ (the "Custodian") under a Custody
         Agreement and Power of Attorney (the "Custody Agreement and Power of
         Attorney"), duly executed and delivered by such Selling Shareholder,
         with the Custodian having the authority to deliver the Shares to be
         sold by such Selling Shareholder hereunder, and such Selling
         Shareholder has duly executed and delivered the Custody Agreement and
         Power of Attorney appointing John J. Klobnak and Robert W. May as such
         Selling Shareholder's agents and attorneys-in-fact (the
         "Attorneys-in-Fact") with the Attorneys-in-Fact having authority to
         execute and deliver this Agreement on behalf of such Selling
         Shareholder, to determine the purchase price to be paid by the
         Underwriters to the Selling Shareholders as provided in Section 2, to
         authorize the delivery of the Shares to be sold by it hereunder and
         otherwise to act on behalf of such Selling Shareholder in connection
         with the transactions contemplated by this Agreement and such Custody
         Agreement.

                  (ix) The Shares represented by the certificates held in
         custody for such Selling Shareholder under the Custody Agreement and
         Power of Attorney are subject to the interests of the Underwriters
         hereunder, and the arrangements made by such Selling Shareholder for
         such custody, and the appointment by such Selling Shareholder of the
         Custodian and of the Attorneys-in-Fact under the Custody Agreement and
         Power of Attorney, are, except as specifically provided therein,
         irrevocable.

                  (x) The obligations of such Selling Shareholder hereunder and
         under the Custody Agreement and Power of Attorney shall not be
         terminated by any Selling Shareholder or operation of law, whether by
         the death or incapacity of any individual Selling Shareholder or, in
         the case of an estate or trust, by the death or incapacity of any
         executor or trustee or the termination of such estate or trust, or, in
         the case of a partnership, corporation or other entity, upon any
         dissolution, winding up, distribution of assets or other event
         affecting the legal existence of such Selling Shareholder, or by the
         occurrence of any other event; and if any individual Selling
         Shareholder or any such executor or trustee should die or become
         incapacitated, or if any such estate or trust should be terminated, or
         if any such partnership, corporation or other entity should dissolve,
         wind up or distribute assets or any other event affecting the legal
         existence of such Selling Shareholder should occur, or if any other
         such event should occur before the delivery of the Shares hereunder,
         certificates representing the Shares shall be delivered by or on behalf
         of each Selling Shareholder in accordance with the terms and conditions
         of this Agreement and of the Custody Agreement; and actions taken by
         the Custodian or by the Attorneys-in-Fact pursuant to the Custody
         Agreement and Power of Attorney shall be as valid as if such death,
         incapacity, termination, dissolution, winding up, distribution of




                                       14

         assets or other event had not occurred, regardless of whether or not
         the Custodian or Attorneys-in-Fact, or any of them, shall have received
         notice of such death, incapacity, termination, dissolution, winding up,
         distribution of assets or other event.

                  (xi) Such Selling Shareholder is not prompted to sell shares
         of Common Stock by any information concerning the Company or any of its
         subsidiaries which is not included in the Registration Statement.

         (c) Any certificate signed by any officer of the Company and delivered
to you or to counsel for the Underwriters shall be deemed a representation and
warranty by the Company to each Underwriter as to the matters covered thereby;
and any certificate signed by or on behalf of the Selling Shareholders as such
and delivered to you or to counsel for the Underwriters shall be deemed a
representation and warranty by the Selling Shareholders to each Underwriter as
to the matters covered thereby.

         5. ADDITIONAL COVENANTS. The Company and, where expressly indicated,
the Selling Shareholders, covenant and agree with the several Underwriters that:

advise the Representatives of any request of the SEC for amendment of the

knowledge prior to the completion of the distribution of the Shares; and the
Company will use its best efforts to prevent the issuance of any such stop order
or other order and, if issued, to secure the prompt removal thereof.

         (c) The Company will not file any amendment or supplement to the

and by the rules and regulations of the SEC thereunder, as from time to time in
force, so far as necessary to permit the continuance of sales of or dealing in
the Shares during such period in accordance with the provisions hereof and as
contemplated by the Prospectus.

         (e) If, during the period when a prospectus relating to any of the
Shares is required to be delivered under the 1933 Act by any Underwriter or
dealer, (i) any event relating to or affecting the Company or of which the
Company shall be advised in writing by the Representatives shall occur as a
result of which, in the opinion of the Company or the Representatives, the
Prospectus as then amended or supplemented would include any untrue statement of
a material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or (ii) it shall be necessary to amend or supplement the
Registration Statement or the Prospectus to comply with the 1933 Act, the 1933
Act Rules and Regulations, the 1934 Act or the 1934 Act Rules and Regulations,
the Company will forthwith at its expense prepare and file with the SEC, and

         (f) During the period when a prospectus relating to any of the Shares
is required to be delivered under the 1933 Act by any Underwriter or dealer, the
Company will furnish such proper information as may be lawfully required and
otherwise cooperate in qualifying the Shares for offer and sale under the
securities or blue sky laws of such jurisdictions as the Representatives may
reasonably designate and will file and make in each year such statements or
reports as are or may be reasonably required by the laws of such jurisdictions;
provided,

to any significant subsidiaries, as that term is defined in the 1933 Act Rules
and Regulations, which are not consolidated in the Company's financial
statements. Any report, document or other information required to be furnished
under this paragraph (h) shall be furnished as soon as practicable after such

         (j) The Company will apply the proceeds from the sale of the Shares as

Shares sold hereunder and except for: (1) sales of shares of Common Stock to the
Company's employees pursuant to the exercise of options or warrants outstanding
on the date hereof under the Company's stock option or warrant plans; or (2) the
issuance of shares of Common Stock to the Company's Preferred Shareholders
pursuant to the conversion of Preferred Stock outstanding on the date hereof.

         (s) If at any time during the 90-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 of the Common 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

         to this Agreement.

                  (iv) For a period of 90 days from the Effective Date, the
         Selling Shareholders will not directly or indirectly offer for sale,
         contract to sell, sell, distribute, grant any option, right or warrant
         to purchase, pledge, hypothecate or otherwise dispose of any shares of
         Common Stock or any securities convertible into, or exercisable or
         exchangeable for, Common Stock or rights to acquire such shares,

         Prospectus and the Prospectus, such Selling Shareholder has not taken
         and will not take, directly or indirectly, any action designed to or

         management, prospects, results of operations or cash flow or of any
         change in information relating to such Selling Shareholder or the
         Company or any new information relating to the Company or relating to
         any matter stated in the Prospectus or any amendment or supplement

         suggests that any statement made in the Registration Statement or the
         Prospectus (as then amended or supplemented, if amended or
         supplemented) is or may be untrue in any material respect or that the
         Registration Statement or Prospectus (as then amended or supplemented,

         1933 Act or any other law.

         6. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The several obligations of

         (b) No Underwriter shall have advised the Company on or prior to the
Closing Date (and, if applicable, the Option Closing Date), that the
Registration Statement or Prospectus or any amendment or supplement thereto
contains an untrue statement of fact which, in the reasonable opinion of counsel
to the Underwriters, is material, or omits to state a fact which, in the
reasonable opinion of such counsel, is material and is required to be stated
therein or is necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

         (c) On the Closing Date (and, if applicable, the Option Closing Date),
you shall have received the opinion of Dankenbring Greiman Osterholt & Hoffmann,

         purpose have been instituted or are pending or contemplated under the
         1933 Act or under the securities laws of any jurisdiction.

                  (ii) The Registration Statement and the Prospectus, and each
         amendment or supplement thereto (including any document incorporated by
         reference into the Prospectus), as of their respective effective or

         of Form S-3 have been satisfied; and, as of the date they were filed
         with the SEC, the documents incorporated by reference in the Prospectus

         obligation of the Company enforceable against the Company in accordance
         with its terms, except as enforceability may be limited by the
         Exceptions and except to the extent the enforceability of the
         indemnification and contribution provisions of Section 7 of the
         Agreement may be limited by public policy considerations as expressed
         in the 1933 Act as construed by courts of competent jurisdiction.

         other jurisdiction in which their ownership or leasing of property or
         conduct of business legally requires such qualification, except where
         the failure to be so qualified, individually or in the aggregate, would
         not have a Material Adverse Effect.

                  (vi) The entities listed on Exhibit A are the only
         subsidiaries, direct or indirect, of the Company. The Company owns,

         such counsel, except as disclosed in the Prospectus, there are no
         outstanding subscriptions, rights, warrants, options, calls,
         convertible securities, commitments of sale, or instruments related to

         or any security convertible into or exercisable or exchangeable for,
         any such shares of capital stock or other ownership interest of any of
         such subsidiaries.

                  (vii) The issuance and sale of the Shares and the execution,
         delivery and performance by the Company of this Agreement, and the
         consummation of the transactions herein contemplated, will not conflict
         with or result in a breach or violation of any of the terms or
         provisions of, or constitute a default under, or result in the creation
         or imposition of any lien, charge or encumbrance upon any properties or
         assets of the Company or any of its subsidiaries under, any indenture,
         mortgage, deed of trust, loan agreement or other agreement or
         instrument known to such counsel after due inquiry to which the Company
         or any of its subsidiaries is a party or by which the Company or any of

         any of its subsidiaries is subject, except to such extent as,
         individually or in the aggregate, does not have a Material Adverse
         Effect, nor will such action result in any violation of the provisions
         of the Company's certificate of incorporation or bylaws or any statute,
         rule, regulation or other law, or any order or judgment known to such
         counsel after due inquiry, of any court or governmental agency or body
         having jurisdiction over the Company or any of its subsidiaries or any
         of their properties.

                  (viii) No consent, approval, authorization, order,
         registration or qualification of or with any court or governmental
         agency or body is required in connection with the execution, delivery
         and performance of this Agreement, and the issuance and sale of the
         Shares or the consummation of the transactions contemplated hereby,
         except such as may be required under the 1933 Act or the 1933 Act Rules
         and Regulations and have been obtained, or as may be required by the

         the Company and its subsidiaries has filed all Notices pursuant to, and
         has obtained all Approvals required to be obtained under, and has
         otherwise complied with all requirements of, all applicable laws and
         regulations in connection with the issuance and sale of the Shares, in
         each case with such exceptions, individually or in the aggregate, as
         would not affect the validity of the Shares, their issuance or the
         transactions contemplated hereby or have a Material Adverse Effect; and
         no such Notices or Approvals are required to be filed or obtained by
         the Company or any of its subsidiaries in connection with the
         execution, delivery and performance of this Agreement, the issuance and
         sale of the Shares or the transactions contemplated hereby, in each
         case with such exceptions, individually or in the aggregate, as would
         not affect the validity of the Shares, their issuance or the
         transactions contemplated hereby or have a Material Adverse Effect.

                  (ix) To the knowledge of such counsel after due inquiry and
         other than as set forth in the Prospectus, there are no legal or
         governmental proceedings pending to which the Company or any of its
         subsidiaries is a party or of which any property of the Company or any
         of its subsidiaries is the subject that, if determined adversely to the
         Company or any of its subsidiaries, would individually or in the
         aggregate have a material adverse effect on the current or future
         consolidated financial position, stockholders' equity or results of
         operations of the Company and its subsidiaries taken as a whole; and,
         to the knowledge of such counsel after due inquiry and other than as
         set forth in the Prospectus, no such proceedings are threatened or
         contemplated by governmental authorities or threatened by others.

         Agreement, will be validly issued, fully paid and non-assessable. All
         corporate action required to be taken by the Company for the
         authorization, issue and sale of the Shares has been duly and validly
         taken. The Shares are duly authorized for trading, subject to official

         from the Company hereunder is not subject to preemptive or other
         similar rights, or any restriction upon the voting or transfer thereof
         pursuant to applicable law or the certificate of incorporation, bylaws

         or exchangeable for, the capital stock of, or other ownership interest
         in, the Company.

                  (xi) To the knowledge of such counsel after due inquiry, the
         Company and each of its subsidiaries hold all licenses, certificates,
         permits and approvals from all state, federal and other regulatory
         authorities, and have satisfied in all material respects the
         requirements imposed by regulatory bodies, administrative agencies or
         other governmental bodies, agencies or officials, that are required for
         the Company and its subsidiaries lawfully to own, lease and operate its
         properties and conduct its business as described in the Prospectus,
         and, to the knowledge of such counsel after due inquiry, each of the
         Company and its subsidiaries is conducting its business in compliance
         in all material respects with all of the laws, rules  and regulations
         of each jurisdiction in which it conducts its business (except to the
         extent the same relate to matters pertaining to government restriction,
         regulation, or control of medical devices, practices, services, fees or
         procedures).

                  (xii) The statements made in the Prospectus under the captions
         "Risk Factors," "Business" (excluding those matters of law or legal
         conclusions pertaining to government restriction, regulation or control
         of medical devices, practices, services, fees or procedures),
         "Description of Securities" and "Shares Eligible For Future Sale," Item
         15 of Part II of the Registration Statement, and in the Company's
         Annual Report on Form 10-K of the year ended April 30, 1998 under Item
         11, "Executive Compensation" and Item 13, "Certain Relationships and
         Related Transactions," to the extent that they constitute summaries of
         documents referred to therein or matters of law or legal conclusions,
         have been reviewed by such counsel and are accurate summaries and
         fairly present the information disclosed therein.

                  (xiii) Neither the Company nor any of its subsidiaries is, or
         with the giving of notice or lapse of time or both would be, in default
         or violation with respect to its certificate of incorporation or
         by-laws. To the best of such counsel's knowledge, neither the Company
         nor any of its subsidiaries is, or with the giving of notice or lapse
         of time



                                       24
<PAGE>   25


         or both would be, in default in the performance or observance of any
         material obligation, agreement, covenant or condition contained in any
         indenture, mortgage, deed of trust, loan agreement, lease or other
         agreement or instrument to which the Company or any of its subsidiaries
         is a party or by which the Company or any of its subsidiaries is bound
         or to which any of the properties or assets of the Company or any of
         its subsidiaries is subject, or in violation of any statutes, laws,
         ordinances or governmental rules or regulations or any orders or
         decrees to which it is subject, including, without limitation, Section
         13 of the 1934 Act, and neither the Company nor any of its subsidiaries
         has failed to obtain any other license, permit, franchise, easement,
         consent, or other governmental authorization necessary to the
         ownership, leasing and operation of its properties or to the conduct of
         its business, which default, violation or failure, individually or in
         the aggregate, would have a Material Adverse Effect.

                  (xiv) To the knowledge of such counsel after due inquiry, (A)
         there are no material (individually, or in the aggregate) legal,
         governmental or regulatory proceedings pending or threatened to which
         the Company or any of its subsidiaries is a party or of which the
         business or properties of the Company or any of its subsidiaries is the
         subject which are not disclosed in the Registration Statement and
         Prospectus, (B) there are no contracts or documents of a character
         required to be described in the Registration Statement or the
         Prospectus or to be filed as an exhibit to the Registration Statement
         which are not described or filed as required, and (C) there are no
         statutes, ordinances, laws, rules or regulations required to be
         described in the Registration Statement or Prospectus which are not
         described as required.

                  (xv) The Company is not and, after giving effect to the
         offering and sale of the Shares, will not be a "holding company," or a
         "subsidiary company" of a "holding company," or an "affiliate" of a
         "holding company" or of a "subsidiary company," as such terms are
         defined in the 1935 Act.

                  (xvi) The Company is not and, after giving effect to the
         offering and sale of the Shares, will not be an "investment company" or
         an entity "controlled" by an "investment company," as such terms are
         defined in the 1940 Act.

                  (xvii) To the best of such counsel's knowledge, all the shares
         of capital stock of the Company issued subsequent to prior three fiscal
         years were issued and sold in compliance with all applicable federal
         and state securities laws.

                  (xviii) To the knowledge of such counsel after due inquiry and
         except as disclosed in the Prospectus, no holder of any security of the
         Company has any right to require registration of shares of Common Stock
         or any other security of the Company because of the filing of the
         Registration Statement or the consummation of the transactions
         contemplated hereby and, except as disclosed in the Prospectus, no
         person



                                       25
<PAGE>   26


         has the right to require registration under the 1933 Act of any shares
         of Common Stock or other securities of the Company.

         Such counsel shall confirm that during the preparation of the
Registration Statement and Prospectus, such counsel participated in conferences
with the Representatives and their counsel and with officers and representatives
of the Company and its independent accountants, at which conferences the
contents of the Registration Statement and the Prospectus (including all
documents filed under the 1934 Act and deemed incorporated by reference therein)
were discussed, reviewed and revised. On the basis of the information which was
developed in the course thereof, considered in light of such counsel's
understanding of applicable law and the experience gained by such counsel
through their practice thereunder, without such counsel assuming responsibility
for the accuracy and completeness of such statements except to the extent
expressly provided above, such counsel shall confirm that nothing came to their
attention that would lead them to believe that either the Registration Statement
(including any document filed under the 1934 Act and deemed incorporated by
reference therein), as of the Effective Date, contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, or the Prospectus or any amendment
or supplement thereto (including any document filed under the 1934 Act and
deemed incorporated by reference therein) as of its respective issue date and as
of the Closing Date, or, if applicable, the Option Closing Date, contained or
contains any untrue statement of a material fact or omitted or omits to state a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading (other than the financial statements or other financial data as to
which such counsel need express no opinion).

         In rendering the foregoing opinion, such counsel may rely, (1) as to
matters involving laws of any jurisdiction other than Missouri or the United
States, upon opinions addressed to the Underwriters of other counsel
satisfactory to them and Bryan Cave LLP, and (2) as to all matters of fact, upon
certificates and written statements of the executive officers of, and
accountants for, the Company, provided, in either case, that such counsel shall
state in their opinion that they and the Underwriters are justified in relying
thereon.

         (d) On the Closing Date (and, if applicable, the Option Closing Date),
you shall have received the opinion of Dankenbring Greiman Osterholt & Hoffmann,
P.C., counsel to the Selling Shareholders, addressed to you and dated the
Closing Date, to the effect that:

                  (i) The Custody Agreement and Power of Attorney has been duly
         executed and delivered by such Selling Shareholders and constitutes a
         legal, valid and binding agreement of such Selling Shareholders
         enforceable in accordance with its terms.

                  (ii) This Agreement has been duly authorized, executed and
         delivered on behalf of the Selling Shareholders, and is a legal, valid
         and binding obligation of the Selling Shareholders. The execution and
         delivery of this Agreement and the Custody



                                       26
<PAGE>   27


         Agreement and Power of Attorney by such Selling Shareholders, the
         consummation by such Selling Shareholders of the transactions
         contemplated herein and therein and the fulfillment by such Selling
         Shareholders of the terms hereof and thereof will not result in a
         breach or violation of any terms or provisions of, or constitute a
         default under, or result in the creation or imposition of any lien,
         charge or encumbrance upon any of the properties or assets of such
         Selling Shareholders under any bond, debenture, note or other evidence
         of indebtedness or any indenture, mortgage, deed of trust, sale and
         leaseback arrangement, joint venture or any other agreement or
         instrument to which any such Selling Shareholder is a party, or by
         which it is bound or to which any of the properties or assets of any
         such Selling Shareholder is subject (or any certificate or articles of
         incorporation or bylaws, partnership agreement, trust document or
         articles of association of any such Selling Shareholder, as
         applicable), or any order or decree, or statute, law, ordinance, rule
         or regulation applicable to any such Selling Shareholder of any court
         or of any governmental agency, authority or body having jurisdiction
         over any such Selling Shareholder or its properties.

                  (iii) Each Selling Shareholder has full legal right, power and
         authority, and any approval required by law (other than as required by
         the 1933 Act, the NASD and state securities and Blue Sky Laws) to sell,
         assign, transfer and deliver the Shares to be sold by such Selling
         Shareholder.

                  (iv) No consent, approval, authorization or order of any
         court, or governmental agency or body is required for consummation of
         the transactions contemplated by this Agreement in connection with the
         Shares to be sold by each Selling Shareholder hereunder except such as
         may be required under the 1933 Act or the 1933 Act Rules and
         Regulations or as may be required by the NASD or under state securities
         laws.

                  (v) Each Selling Shareholder has good, valid and marketable
         title to the Shares being sold by such Selling Shareholder hereunder,
         free and clear of all liens, mortgages, pledges, encumbrances, claims,
         equities and security interests whatsoever, including any restriction
         on transfer other than pursuant to this Agreement and the Custody
         Agreement and Power of Attorney, and has transferred to the
         Underwriters good, valid and marketable title to the Shares being sold
         by such Selling Shareholder on the Closing Date (and, if applicable,
         the Option Closing Date), free and clear of all liens, mortgages,
         pledges, encumbrances, claims, equities and security interests
         whatsoever, including any restriction or transfer other than pursuant
         to this Agreement and the Custody Agreement and Power of Attorney.

         In rendering the foregoing opinion, such counsel may rely, (1) as to
matters involving laws of any jurisdiction other than Missouri or the United
States, upon opinions addressed to the Underwriters of other counsel
satisfactory to them and Bryan Cave LLP, and (2) as to all matters of fact, upon
certificates and written statements of the Selling Shareholders, provided, in
either 



                                       27
<PAGE>   28


case, that such counsel shall state in their opinion that they and the
Underwriters are justified in relying thereon.

         (e) You shall have received on the Closing Date (and, if applicable,
the Option Closing Date), from Bryan Cave LLP, counsel to the Underwriters, such
opinion or opinions, dated the Closing Date (and, if applicable, the Option
Closing Date) with respect to such matters as you may reasonably require; and
the Company and Selling Shareholders shall have furnished to such counsel such
documents as they reasonably request for the purposes of enabling them to review
or pass on the matters referred to in this Section 6 and in order to evidence
the accuracy, completeness and satisfaction of the representations, warranties
and conditions herein contained.

         (f) You shall have received at or prior to the Closing Date from Bryan
Cave LLP a memorandum or memoranda, in form and substance satisfactory to you,
with respect to the qualification for offering and sale by the Underwriters of
the Shares under state securities or Blue Sky laws of such jurisdictions as the
Underwriters may have designated to the Company.

         (g) On the business day immediately preceding the date of this
Agreement and on the Closing Date (and, if applicable, the Option Closing Date),
you shall have received from PricewaterhouseCoopers LLP, a letter or letters,
dated the date of this Agreement and the Closing Date (and, if applicable, the
Option Closing Date), respectively, in form and substance satisfactory to you,
confirming that they are independent public accountants with respect to the
Company within the meaning of the 1933 Act and the published Rules and
Regulations, and stating to the effect set forth in Schedule V hereto.

         (h) Except as contemplated in the Prospectus, (i) neither the Company
nor any of its subsidiaries shall have sustained since the date of the latest
audited financial statements included or incorporated by reference in the
Prospectus any loss or interference with its business from fire, explosion,
flood or other calamity, whether or not covered by insurance, or from any labor
dispute or court or governmental action, order or decree; and (ii) subsequent to
the respective dates as of which information is given in the Registration
Statement and the Prospectus, neither the Company nor any of its subsidiaries
shall have incurred any liability or obligation, direct or contingent, or
entered into any transactions, and there shall not have been any change in the
capital stock or short-term or long-term debt of the Company and its
subsidiaries or any change, or any development involving or which might
reasonably be expected to involve a prospective change in the condition
(financial or other), net worth, business, affairs, management, prospects,
results of operations or cash flow of the Company or its subsidiaries, the
effect of which, in any such case described in clause (i) or (ii), is in your
reasonable judgment so material or adverse as to make it impracticable or
inadvisable to proceed with the public offering or the delivery of the Shares
being delivered on such Closing Date (and, if applicable, the Option Closing
Date) on the terms and in the manner contemplated in the Prospectus.

         (i) There shall not have occurred any of the following: (i) a
suspension or material limitation in trading in securities generally on the New

date hereof; (iii) a general moratorium on commercial banking activities
declared by either federal or any state authorities; (iv) the outbreak or
escalation of hostilities involving the United States or the declaration by the
United States of a national emergency or war, which in your judgment makes it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Shares in the manner contemplated in the Prospectus; or (v) any calamity
or crisis, change in national, international or world affairs, act of God,
change in the international or domestic markets, or change in the existing
financial, political or economic conditions in the United States or elsewhere,
which in your judgment makes it impracticable or inadvisable to proceed with the
public offering or the delivery of the Shares in the manner contemplated in the
Prospectus.

         (j) You shall have received certificates, dated the Closing Date (and,
if applicable, the Option Closing Date) and signed by the Chief Executive

         satisfied;

                  (ii) they have carefully examined the Registration Statement
         and the Prospectus as amended or supplemented and all documents
         incorporated by reference therein and nothing has come to their
         attention that would lead them to believe that either the Registration
         Statement or the Prospectus, or any amendment or supplement thereto or
         any documents incorporated by reference therein as of their respective
         effective, issue or filing dates, contained, and the Prospectus as

         of the circumstances under which they were made, not misleading;

                  (iii) since the Effective Date, there has occurred no event
         required to be set forth in an amendment or supplement to the
         Registration Statement or the Prospectus which has not been so set
         forth and there has been no document required to be filed under the
         1934 Act and the 1934 Act Rules and Regulations that upon such filing
         would be deemed to be incorporated by reference into the Prospectus
         that has not been so filed;

                  (iv) all representations and warranties made herein by the
         Company are true and correct at such Closing Date, with the same effect

         Company on or prior to such Closing Date have been duly performed and

         loss or interference with its business from fire, explosion, flood or
         other calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree;

                  (vi) except as disclosed in the Prospectus, subsequent to the
         respective dates as of which information is given in the Registration

         has not been any change in the capital stock or material increase in
         the short-term debt or long-term debt of the Company or any of its
         subsidiaries or any material adverse change or any development
         involving or which may reasonably be expected to involve a prospective
         material adverse change, in the condition (financial or other), net
         worth, business, affairs, management, prospects, results of operations
         or cash flow of the Company and its subsidiaries taken as a whole; and

Underwriter for and against any losses, damages or liabilities to which the
Company may become subject, under the 1933 Act or otherwise, insofar as such
losses, damages or liabilities (or actions or claims in respect thereof) arise
out of or are based upon (i) an untrue statement or alleged untrue statement of
a material fact contained in any Preliminary Prospectus, the Registration
Statement, the Prospectus or any other prospectus relating to the Shares, or any
amendment or supplement thereto, or any Blue Sky Application, or (ii) the
omission or alleged omission to state therein a material fact required to be

as such expenses are incurred (including such losses, damages, liabilities or
expenses to the extent of the aggregate amount paid in settlement of any such
action or claim, provided that (subject to Section 7(d) hereof) any such
settlement is effected with the written consent of such Selling Shareholder).

         (c) Each Underwriter, severally and not jointly, will indemnify and
hold harmless the Company and each Selling Shareholder for and against any
losses, damages or liabilities to which the Company may become subject, under
the 1933 Act or otherwise, insofar as such losses, damages or liabilities (or
actions or claims in respect thereof) arise out of or are based upon an untrue
statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement, the Prospectus or any other
prospectus relating to the Shares, or any amendment or supplement thereto, or
any Blue Sky Application, or arise out of are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement, the Prospectus or any other prospectus
relating to the Shares, or any such amendment or supplement, or any Blue Sky
Application, in reliance upon and in conformity with written



                                       32
<PAGE>   33


information relating to the Underwriter furnished to the Company by you or by
any Underwriter through you, expressly for use in the preparation thereof (as
provided in Section 14 hereof), and will reimburse the Company or any such
Selling Shareholder for any legal or other expenses incurred by the Company or
any such Selling Shareholder, as the case may be, in connection with
investigating or defending any such action or claim as such expenses are
incurred (including such losses, damages, liabilities or expenses to the extent
of the aggregate amount paid in settlement of any such action or claim, provided
that (subject to Section 7(d) hereof) any such settlement is effected with the
written consent of the Underwriters).

         (d) Promptly after receipt by an indemnified party under Section 7(a),
7(b) or 7(c) hereof of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against an
indemnifying party under Section 7(a), 7(b) or 7(c) hereof, notify each such
indemnifying party in writing of the commencement thereof, but the failure so to
notify such indemnifying party shall not relieve such indemnifying party from
any liability except to the extent that it has been prejudiced in any material
respect by such failure or from any liability that it may have to any such
indemnified party otherwise than under Section 7(a), 7(b) or 7(c) hereof. In
case any such action shall be brought against any such indemnified party and it
shall notify each indemnifying party of the commencement thereof, each such
indemnifying party shall be entitled to participate therein and, to the extent
that it shall wish, jointly with any other indemnifying party under Section
7(a), 7(b) or 7(c) hereof similarly notified, to assume the defense thereof,
with counsel satisfactory to such indemnified party (who shall not, except with
the consent of such indemnified party, be counsel to such indemnifying party),
and, after notice from such indemnifying party to such indemnified party of its
election so to assume the defense thereof, such indemnifying party shall not be
liable to such indemnified party under Section 7(a), 7(b) or 7(c) hereof for any
legal expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. The indemnified party shall have the
right to employ its own counsel in any such action, but the fees and expenses of
such counsel shall be at the expense of such indemnified party unless (i) the
employment of counsel by such indemnified party at the expense of the
indemnifying party has been authorized by the indemnifying party, (ii) the
indemnified party shall have been advised by such counsel that there may be a
conflict of interest between the indemnifying party and the indemnified party in
the conduct of the defense, or certain aspects of the defense, of such action
(in which case the indemnifying party shall not have the right to direct the
defense of such action with respect to those matters or aspects of the defense
on which a conflict exists or may exist on behalf of the indemnified party) or
(iii) the indemnifying party shall not in fact have employed counsel reasonably
satisfactory to such indemnified party to assume the defense of such action, in
any of which events such fees and expenses to the extent applicable shall be
borne, and shall be paid as incurred, by the indemnifying party. If at any time
such indemnified party shall have requested such indemnifying party under
Section 7(a), 7(b) or 7(c) hereof to reimburse such indemnified party for fees
and expenses of counsel, such indemnifying party agrees that it shall be liable
for any settlement of the nature contemplated by Section 7(a), 7(b) or 7(c)
hereof effected without its written consent if (i) such settlement is entered
into more than 45 days after receipt by such



                                       33
<PAGE>   34


indemnifying party of such request for reimbursement, (ii) such indemnifying
party shall have received notice of the terms of such settlement at least 30
days prior to such settlement being entered into and (iii) such indemnifying
party shall not have reimbursed such indemnified party in accordance with such
request for reimbursement prior to the date of such settlement. No such
indemnifying party shall, without the written consent of such indemnified party,
effect the settlement or compromise of, or consent to the entry of any judgment
with respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not such
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (A) includes an unconditional
release of such indemnified party from all liability arising out of such action
or claim and (B) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of any such indemnified party.
In no event shall such indemnifying parties be liable for the fees and expenses
of more than one counsel, including any local counsel, for all such indemnified
parties in connection with any one action or separate but similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances.

         (e) If the indemnification provided for in this Section 7 is
unavailable to or insufficient to indemnify or hold harmless an indemnified
party under Section 7(a), 7(b) or 7(c) hereof in respect of any losses, damages
or liabilities (or actions or claims in respect thereof) referred to therein,
then each indemnifying party under Section 7(a), 7(b) or 7(c) hereof shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, damages or liabilities (or actions or claims in respect thereof)
in such proportion as is appropriate to reflect the relative benefits received
by the Company and the Selling Shareholders, on the one hand, and the
Underwriters, on the other hand, from the offering of the Shares. If, however,
the allocation provided by the immediately preceding sentence is not permitted
by applicable law or if the indemnified party failed to give the notice required
under Section 7(d) hereof and such indemnifying party was prejudiced in a
material respect by such failure, then each such indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault, as applicable, of the Company and the Selling Shareholders,
on the one hand, and the Underwriters, on the other hand, in connection with the
statements or omissions that resulted in such losses, damages or liabilities (or
actions or claims in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by, as applicable, the Company
and the Selling Shareholders, on the one hand, and the Underwriters, on the
other hand, shall be deemed to be in the same proportion as the total net
proceeds from such offering (before deducting expenses) received by the Company
and the Selling Shareholders bear to the total underwriting discounts and
commissions received by the Underwriters. The relative fault, as applicable, of
the Company or the Selling Shareholders, on the one hand, and the Underwriters,
on the other hand, 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 the Company or the Selling Shareholders, on the one hand, or the
Underwriters, on the other hand, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company,




                                       34
<PAGE>   35


the Selling Shareholders and the Underwriters agree that it would not be just
and equitable if contribution pursuant to this Section 7(e) were determined by
pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation that does not take account of
the equitable considerations referred to above in this Section 7(e). The amount
paid or payable by such an indemnified party as a result of the losses, damages
or liabilities (or actions or claims in respect thereof) referred to above in
this Section 7(e) shall be deemed to include any legal or other expenses
incurred by such indemnified party in connection with investigating or defending
any such action or claim. Notwithstanding the provisions of this Section 7(e),
no Underwriter shall be required to contribute any amount in excess of the
amount by which the total price at which the Shares underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages that such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The obligations of the
Underwriters in this Section 7(e) to contribute are several in proportion to
their respective underwriting obligations with respect to the Shares and not
joint.

         (f) The obligations of the Company and the Selling Shareholders under
this Section 7 shall be in addition to any liability that the Company and the
Selling Shareholders may otherwise have and shall extend, upon the same terms
and conditions, to each officer, director, employee, agent or other
representative and to each person, if any, who controls any Underwriter within
the meaning of the 1933 Act; and the obligations of the Underwriters under this
Section 7 shall be in addition to any liability that the respective Underwriters
may otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company who signed the Registration Statement and to
each person, if any, who controls the Company within the meaning of the 1933 Act
and to each person, if any, who controls the Selling Shareholders within the
meaning of the 1933 Act.

         (g) The liability of a Selling Shareholder for a breach of its
representations and warranties set forth in this Agreement and pursuant to
Section 7(a) shall not exceed the product of the number of Shares sold by such
Selling Shareholder and the public offering prices per share of the Shares set
forth in the Prospectus.

         (h) The parties to this Agreement hereby acknowledge that they are
sophisticated business persons who were represented by counsel during the
negotiations regarding the provisions hereof, including, without limitation, the
provisions of this Section 7, and are fully informed regarding such provisions.
They further acknowledge that the provisions of this Section 7 fairly allocate
the risks in light of the ability of the parties to investigate the Company and
its business in order to assure that adequate disclosure is made in the
Registration Statement, any Preliminary Prospectus, the Prospectus, and any
supplement or amendment thereof, as required by the 1933 Act.

         8. REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. The respective
representations, warranties, agreements and statements of the Company and the
Selling Shareholders and the Underwriters, as set forth in this Agreement or
made by or on behalf of them, respectively, pursuant to this Agreement, shall
remain operative and in full force and effect regardless of any investigation
(or any statement as to the results thereof) made by or on behalf of any
Underwriter or any controlling person of any Underwriter, the Company or any of
its officers, directors or any controlling persons, or the Selling Shareholders,
and shall survive delivery of and payment for the Shares hereunder.

         9. SUBSTITUTION OF UNDERWRITERS. (a) If any Underwriter shall default
in its obligation to purchase the Shares which it has agreed to purchase
hereunder, you may in your discretion arrange for you or another party or other
parties to purchase such Shares on the terms contained herein. If within
thirty-six hours after such default by any Underwriter you do not arrange for
the purchase of such Shares, then the Company shall be entitled to a further
period of thirty-six hours within which to procure another party or parties
reasonably satisfactory to you to purchase such Shares on such terms. In the
event that, within the respective prescribed periods, you notify the Company
that you have so arranged for the purchase of such Shares, or the Company
notifies you that it has so arranged for the purchase of such Shares, you or the
Company shall have the right to postpone the Closing Date for a period of not
more than seven days, in order to effect whatever changes may thereby be made
necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments to the Registration Statement or the Prospectus which in your opinion
may thereby be made necessary. The term "Underwriter" as used in this Agreement
shall include any persons substituted under this Section 9 with like effect as
if such person had originally been a party to this Agreement with respect to
such Shares.

         (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters made by you and the Company
and the Selling Shareholders as provided in subsection (a) above, the aggregate
number of Shares which remains unpurchased does not exceed one-eleventh of the
total Shares to be sold on the Closing Date, then the Company and the Selling
Shareholders shall have the right to require each non-defaulting Underwriter to
purchase the Shares which such Underwriter agreed to purchase hereunder and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters made by you and the Company
and the Selling Shareholders as provided in subsection (a) above, the number of
Shares which remains unpurchased exceeds one-eleventh of the total Shares to be
sold on the Closing Date, or if the Company and the Selling Shareholders shall
not exercise the right described in subsection (b) above to require the
non-defaulting Underwriters to purchase Shares of the defaulting



                                       36
<PAGE>   37


Underwriter or Underwriters, then this Agreement (or, with respect to the Option
Closing Date, the obligations of the Underwriters to purchase and of the Company
and the Selling Shareholders to sell the Option Shares) shall thereupon
terminate, without liability on the part of any non-defaulting Underwriter or
the Company and the Selling Shareholders except for the expenses to be borne by
the Company and the Underwriters as provided in Section 11 hereof and the
indemnity and contribution agreements in Section 7 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

         10. EFFECTIVE DATE AND TERMINATION. (a) This Agreement shall become
effective at 1:00 p.m., St. Louis time, on the first business day following the
effective date of the Registration Statement, or at such earlier time after the
effective date of the Registration Statement as you in your discretion shall
first release the Shares for offering to the public; provided, however, that the
provisions of Section 7 and 11 shall at all times be effective. For the purposes
of this Section 10(a), the Shares shall be deemed to have been released to the
public upon release by you of the publication of a newspaper advertisement
relating to the Shares or upon release of telegrams, facsimile transmissions or
letters offering the Shares for sale to securities dealers, whichever shall
first occur.

         (b) This Agreement may be terminated by you at any time before it
becomes effective in accordance with Section 10(a) by notice to the Company and
the Selling Shareholders; provided, however, that the provisions of this Section
10 and of Section 7 and Section 11 hereof shall at all times be effective. In
the event of any termination of this Agreement pursuant to Section 9 or this
Section 10(b) hereof, the Company and the Selling Shareholders shall not then be
under any liability to any Underwriter except as provided in Section 7 or
Section 11 hereof.

         (c) This Agreement may be terminated by you at any time at or prior to
the Closing Date by notice to the Company and the Selling Shareholders if any
condition specified in Section 6 hereof shall not have been satisfied on or
prior to the Closing Date. Any such termination shall be without liability of
any party to any other party except as provided in Sections 7 and 11 hereof.

         (d) This Agreement also may be terminated by you, by notice to the
Company and the Selling Shareholders, as to any obligation of the Underwriters
to purchase the Option Shares, if any condition specified in Section 6 hereof
shall not have been satisfied at or prior to the Option Closing Date or as
provided in Section 9 of this Agreement.

         If you terminate this Agreement as provided in Sections 10(b), 10(c) or
10(d), you shall notify the Company and the Selling Shareholders by telephone or
telegram, confirmed by letter.

         11. COSTS AND EXPENSES. The Company, whether or not the transactions
contemplated hereby are consummated or this Agreement is prevented from becoming
effective under Section 10 hereof or is terminated, will bear and pay the costs
and expenses incident to the registration of the Shares and public offering
thereof, including, without limitation, (a) all



                                       37
<PAGE>   38


expenses (including stock transfer taxes) incurred in connection with the
delivery to the several Underwriters of the Shares, the filing fees of the SEC,
the fees and expenses of the Company's counsel and accountants, (b) the
preparation, printing, filing, delivery and shipping of the Registration
Statement, each Preliminary Prospectus, the Prospectus and any amendments or
supplements thereto (except as otherwise expressly provided in Section 5(d)
hereof) and the printing, delivery and shipping of this Agreement and other
underwriting documents, including the Agreement Among Underwriters, the Selected
Dealer Agreement, Underwriters' Questionnaires and Powers of Attorney and Blue
Sky Memoranda, and any instruments or documents related to any of the foregoing,
(c) the furnishing of copies of such documents (except as otherwise expressly
provided in Section 5(d) hereof) to the Underwriters, (d) the registration or
qualification of the Shares for offering and sale under the securities laws of
the various states and other jurisdictions, including the fees and disbursements
of counsel to the Underwriters relating to such registration or qualification
and in connection with preparing any Blue Sky Memoranda or related analysis, (e)
the filing fees of the NASD (if any) and fees and disbursements of counsel to
the Underwriters relating to any review of the offering by the NASD, (f) all
printing and engraving costs related to preparation of the certificates for the
Shares, including transfer agent and registrar fees, (g) all fees and expenses
relating to the authorization of the Shares for trading on the Nasdaq National
Market, (h) all travel expenses, including air fare and accommodation expenses,
of representatives of the Company in connection with the offering of the Shares,
and (i) all of the other costs and expenses incident to the performance by the
Company of the registration and offering of the Shares; provided, that each
Selling Shareholder, whether or not the transactions contemplated hereby are
consummated or this Agreement is prevented from becoming effective under Section
10 hereof or is terminated, will pay or cause to be paid all costs and expenses
incident to the performance of such Selling Shareholder's obligations hereunder
which are not otherwise specifically provided for in this Section; including (i)
any fees and expenses of counsel for such Selling Shareholder, (ii) such Selling
Shareholder's pro rata share of the fees and expenses of the Attorneys-in-Fact
and the Custodian, and (iii) all expenses (including stock transfer taxes)
incident to the sale and delivery of the Shares to be sold by such Selling
Shareholder to the Underwriters hereunder; [provided further, that the
Underwriters will bear and pay the fees and expenses of the Underwriters'
counsel (except as provided in this Section 11), the Underwriters' out-of-pocket
expenses, and any advertising costs and expenses incurred by the Underwriters
incident to the public offering of the Shares.]

         If this Agreement is terminated by you in accordance with the
provisions of Section 10(c), the Company and each of the Selling Shareholders
pro rata (based on the number of Shares to be sold by the Company and the
Selling Shareholders hereunder) shall reimburse the Underwriters for all of
their out-of-pocket expenses, including the fees and disbursements of counsel to
the Underwriters.

         12. DEFAULT OF SELLING SHAREHOLDERS. Failure or refusal by any of the
Selling Shareholders to sell and deliver on the Closing Date the Shares agreed
to be sold and delivered by such Selling Shareholder shall in no manner relieve
the other Selling Shareholders or the




                                       38
<PAGE>   39


Company of their respective obligations under this Agreement. If any Selling
Shareholder should fail or refuse to sell and deliver his Shares, the remaining
Selling Shareholders shall have the right hereby granted to increase, pro rata
or otherwise, the number of Shares to be sold by them hereunder to the total
number of Shares to be sold by all Selling Shareholders as set forth in Schedule
I. If the remaining Selling Shareholders do not fully exercise the right to
increase the number of Shares to be sold by them, the Underwriters, at your
option, will have the right to elect to purchase or not to purchase the Shares
to be sold by the Company and the remaining Selling Shareholders. In the event
the Underwriters purchase the Shares of the Company and such other Selling
Shareholders pursuant to this Section 12, the Closing Date shall be postponed
for a period of not more than seven days in order that the Registration
Statement and Prospectus or other documents may be amended or supplemented to
the extent necessary under the provisions of the 1933 Act and the 1933 Act Rules
and Regulations or under the securities laws of any jurisdiction. If the
Underwriters determine not to purchase the Shares of the Company and the other
Selling Shareholders, if any, this Agreement shall terminate and neither the
Company nor the Underwriters nor any other Selling Shareholder shall be under
any obligation under this Agreement except as provided in Section 7 hereof and
except for the obligation of the Company to pay for such expenses as are set
forth in Section 11 hereof. Nothing herein shall relieve a defaulting Selling
Shareholder from liability for his default or from liability under Section 7
hereof or for expenses imposed by this Agreement upon such Selling Shareholder.

         13. NOTICES. All notices or communications hereunder, except as herein
otherwise specifically provided, shall be in writing and if sent to the

         Pursuant to Section 6(g) of the Underwriting Agreement,
PricewaterhouseCoopers LLP shall furnish letters to the Underwriters to the
effect that:

                  (i)   They are independent certified public accountants with
respect to the Company and its subsidiaries within the meaning of the 1933 Act
and the applicable Rules and Regulations thereunder.

                  (ii)  In their opinion, the financial statements and any
supplementary financial information and schedules audited (and, if applicable,
prospective financial statements and/or pro forma financial information
examined) by them and included or incorporated by reference in the Prospectus or
the Registration Statement comply as to form in all material respects with the
applicable accounting requirements of the 1933 Act and the applicable Rules and
Regulations with respect to registration statements on Form S-3; and, if
applicable, they have made a review in accordance with standards established by
the American Institute of Certified Public Accountants of the unaudited
consolidated interim financial statements, selected financial data, pro forma
financial information, prospective financial statements and/or condensed
financial statements derived from audited financial statements of the Company
for the periods specified in such letter, as indicated in their reports thereon,
copies of which have been furnished to the Representatives of the Underwriters
(the "Representatives").

                  (iii) On the basis of limited procedures, not constituting an
audit in accordance with generally accepted auditing standards, consisting of a
reading of the unaudited financial statements and other information referred to
below, performing the procedures specified by the AICPA for a review of interim
financial information as discussed in SAS No. 71, Interim Financial Information,
on the latest available interim financial statements of the Company and its
subsidiaries, inspection of the minute books of the Company and its subsidiaries
since the date of the latest audited financial statements included in the
Prospectus, inquiries of officials of the Company and its subsidiaries
responsible for financial and accounting matters and such other inquiries and
procedures as may be specified in such letter, nothing came to their attention
that caused them to believe that:

                           (A) any material modifications should be made to the
                  unaudited statements of consolidated income, statements of
                  consolidated financial position and statements of consolidated
                  cash flows included or incorporated by reference in the
                  Prospectus for them to be in conformity with generally
                  accepted accounting principles, or the unaudited statements of
                  consolidated income, statements of consolidated financial
                  position and statements of consolidated cash flows included in
                  the Prospectus do not comply as to form in all material
                  respects with the applicable accounting requirements of the
                  1933 Act and the related published Rules and Regulations
                  thereunder.

                           (B) any other unaudited income statement data and
                  balance sheet items included or incorporated by reference in
                  the Prospectus do not agree with the corresponding items in
                  the unaudited consolidated financial statements from which
                  such data and items were derived, and any such unaudited data
                  and items were not determined on a basis substantially
                  consistent with the basis for the corresponding amounts in the
                  audited consolidated financial statements included or
                  incorporated by reference in the Prospectus.

                           (C) the unaudited financial statements which were not
                  included or incorporated by reference in the Prospectus but
                  from which were derived any unaudited condensed financial
                  statements referred to in Clause (A) and any unaudited income
                  statement data and balance sheet items included in the
                  Prospectus and referred to in Clause (B) were not determined
                  on a basis substantially consistent with the basis for the
                  audited consolidated financial statements included or
                  incorporated by reference in the Prospectus.

                           (D) any unaudited pro forma consolidated condensed
                  financial statements included or incorporated by reference in
                  the Prospectus do not comply as to form in all material
                  respects with the applicable accounting requirements of the
                  1933 Act and the published rules and regulations thereunder or
                  the pro forma adjustments have not been properly applied to
                  the historical amounts in the compilation of those statements.

                           (E) as of a specified date not more than five days
                  prior to the date of such letter, there have been any changes
                  in the consolidated capital stock or any increase in the
                  consolidated long-term debt of the Company and its
                  subsidiaries, or any decreases in consolidated working
                  capital, net current assets or net assets, or any changes in
                  any other items specified by the Representatives, in each case
                  as compared with amounts shown in the latest balance sheet
                  included or incorporated by reference in the Prospectus,
                  except in each case for changes, increases or decreases which
                  the Prospectus discloses have occurred or may occur or which
                  are described in such letter.

                           (F) for the period from the date of the latest
                  financial statements included or incorporated by reference in
                  the Prospectus to the specified date referred to in Clause (E)
                  there were any decreases in consolidated net revenues or
                  operating profit or the total or per share amounts of
                  consolidated net income or any changes in any other items
                  specified by the Representatives, in each case as compared
                  with the comparable period of the preceding year and with any
                  other period of corresponding length specified by the
                  Representatives, except in each case for changes, decreases or
                  increases which the Prospectus discloses have occurred or may
                  occur or which are described in such letter.

                  (iv) In addition to the audit referred to in their report(s)
included or incorporated by reference in the Prospectus and the limited
procedures, inspection of minute books, inquiries and other procedures referred
to in paragraph (iii) above, they have carried out certain specified procedures,
not constituting an audit in accordance with generally accepted auditing
standards, with respect to certain amounts, percentages and financial
information specified by the Representatives, which are derived from the general
accounting records of the Company and its subsidiaries for the periods covered
by their reports and any interim or other periods since the latest period
covered by their reports, which appear or are incorporated by reference in the
Prospectus, or in Part II of, or in exhibits and schedules to, the Registration
Statement specified by the Representatives, and have compared certain of such
amounts, percentages and financial information with the accounting records of
the Company and its subsidiaries and have found them to be in agreement.

Board of Directors
Laser Vision Centers, Inc.
540 Maryville Centre Drive
Suite 200
St. Louis, Missouri 63141


Gentlemen:

     We have acted as Securities Counsel for Laser Vision Centers, Inc. (the
"Company") with respect to the Registration Statement on Form S-3 (the
"Registration Statement"), filed by the Company with the Securities and Exchange
Commission for the purpose of registering under the Securities Act of 1933, as
amended, up to 1,978,000 shares of Common Stock, par value $.01 per share (the
"Common Stock").

     We have examined corporate records of the Company, laws and regulations and
other information we have deemed relevant, including the Company's charter,
by-laws and certificates received from state officials and from officers of the
Company. In delivering this opinion, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to the originals of all documents submitted to us as certified,
photostatic or conformed copies and the correctness of statements submitted to
us by officers of the Company.

     Based solely on the foregoing, we are of the opinion that:

     1.  The Company is a corporation duly incorporated, validly existing and in
         good standing under the laws of the State of Delaware.

     2.  The Common Stock, if and when issued and paid for in accordance with
         the terms of the Underwriting Agreement among the Company, the Selling
         Shareholders, A.G. Edwards & Sons, Inc. and Prudential Securities
         Incorporated, will be legally issued, fully paid and nonassessable.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to us under the caption "Legal Matters" in the
Prospectus which is a part of the Registration Statement.



                                       Very truly yours,
