         2.      REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company
                 hereby represents and warrants as follows:

   
                 (a)      The Company has not received, and has no notice of,
any order of the Commission preventing or suspending the use of any Preliminary
Prospectus, or instituted proceedings for that purpose, and each Preliminary
Prospectus, at the time of filing thereof, conformed in all material respects
to the requirements of the Act and the Rules and Regulations.  When the
Registration Statement became or becomes, as the case may be, effective (the
"Effective Date") and at all times subsequent thereto up to and at the Closing
Date (as hereinafter defined), any later date on which Option Shares are to be
purchased (the "Option Closing Date") and when any post-effective amendment to
the Registration Statement becomes effective or any amendment or supplement to
the Prospectus is filed with the Commission, (i) the Registration Statement and
Prospectus, and any amendments or supplements thereto, will contain all
statements which are required to be stated therein by, and will comply with the
requirements of, the Act and the Rules and Regulations, and (ii) neither the
Registration Statement nor the Prospectus, nor any amendment or supplement
thereto, will include 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.  The foregoing representations and
warranties in this section 2(a) do not apply to any statements or omissions
made in reliance on and in conformity with the information contained in the
section of the Prospectus entitled "Underwriting" (except for the _____
paragraph thereof) and the information in the last paragraph on the front cover
page of the Prospectus.  The Company has not distributed any offering material
in connection with the offering or sale of the Shares other than the
Registration Statement, the Preliminary Prospectus, the Prospectus, the
Offering Memorandum or any other materials, if any, permitted by the Act.
    

                 (b)      The Company has been duly incorporated and is validly
existing as a corporation in good standing under the laws of the State of
Washington, with full corporate power and authority to own, lease and operate
its properties and conduct its





                                       3
<PAGE>   4
   
business as described in the Registration Statement.  The Company is duly
qualified to do business as a foreign corporation in good standing in each
jurisdiction where the ownership or leasing of its properties or the conduct of
its business requires such qualification, except where the failure to so qualify
would not have a material adverse effect on the business, properties, financial
condition or results of operations of the Company and its Subsidiaries (as
hereinafter defined) taken as a whole (a "Material Adverse Effect").  The
Company has no subsidiaries (as defined in the Rules and Regulations) other than
Innova Europe Limited and Techinnova S.A. de C.V. (collectively, the
"Subsidiaries").  The Company owns 99% of the outstanding common stock of each
subsidiary.  Other than the Subsidiaries, the Company does not own, directly or
indirectly, any shares of stock or any other equity or long-term debt securities
of any corporation or have any equity interest in any firm, partnership, joint
venture, association or other entity. Complete and correct copies of the
certificates of incorporation and of the bylaws of the Company and the
Subsidiaries and all amendments thereto have been delivered to the
Representatives, and except as set forth in the exhibits to the Registration
Statement no changes therein will be made subsequent to the date hereof and
prior to the Closing Date or, if later, the Option Closing Date. Each Subsidiary
has been duly incorporated and is validly existing as a corporation in good
standing under the laws of the jurisdiction of its incorporation, with full
corporate power and authority to own, lease and operate its properties and to
conduct its business as described in the Registration Statement.  Each
Subsidiary is duly qualified to do business as a foreign corporation in good
standing in each jurisdiction where the ownership or leasing of the properties
or the conduct of its business requires such qualification, except where the
failure to so qualify would not have a Material Adverse Effect.  All of the
outstanding shares of capital stock of each of the Subsidiaries have been duly
authorized and validly issued, are fully paid and non-assessable and are owned
by the Company subject to no security interest, other encumbrance or adverse
claims.  No options, warrants or other rights to purchase, agreements or other
obligation to issue or other rights to convert any obligation into shares of
capital stock or ownership interests in the Subsidiaries are outstanding.
Techinnova S.A. de C.V. does not own any assets or properties, has no
liabilities, and no employees, and the Company conducts no business through such
subsidiary. INNOVA Europe Limited employs seven customer service representatives
of the Company, but does not own any material assets, and did not generate
material revenues for the Company during the nine months ended December 31, 1996
or the six months ended June 30, 1997. Neither Subsidiary is material within the
meaning of the Rules and Regulations and neither Subsidiary is required to be
listed on Exhibit 21 to Registration Statement.\
    

                 (c)      The Company has full power and authority (corporate
and otherwise) to enter into this Agreement and to perform the transactions
contemplated hereby.  This Agreement has been duly authorized, executed and
delivered by the Company and is





                                       4
<PAGE>   5
   
a valid and binding agreement on the part of the Company, enforceable against
the Company in accordance with its terms, except as rights to indemnity and
contribution hereunder may be limited by applicable laws or equitable
principles and except as enforcement hereof may be limited by applicable
bankruptcy, insolvency, reorganization or other similar laws relating to or
affecting creditors' rights generally or by general equitable principles.  The
performance of this Agreement by the Company and the consummation by the
Company of the transactions herein contemplated will not result in a breach or
violation of any of the terms and provisions of, or constitute a default under,
(i) any indenture, mortgage, deed of trust, loan agreement, bond, debenture,
note agreement or other evidence of indebtedness, or any lease, contract or
other agreement or instrument to which the Company or any Subsidiary is a party
or by which its properties are bound, or (ii) the certificate of incorporation
or bylaws of the Company or any Subsidiary or (iii) any law, order, rule,
regulation, writ, injunction or decree of any court or governmental agency or
body to which the Company or any Subsidiary is subject.  The Company is not
required to obtain or make (as the case may be) any consent, approval,
authorization, order, designation or filing by or with any court or regulatory,
administrative or other governmental agency or body as a requirement for the
consummation by the Company of the transactions herein contemplated, except
such as may be required under the Act, the Securities Exchange Act of 1934, as
amended (the "Exchange Act") or under state securities or blue sky ("Blue Sky")
laws or under the rules and regulations of the National Association of
Securities Dealers, Inc. ("NASD"), or under applicable Canadian securities law.
    

   
                 (d)      There is not pending or, to the Company's knowledge,
threatened, any action, suit, claim, proceeding or investigation against the
Company or its Subsidiaries or any of their respective officers or any of their
respective properties, assets or rights before any court or governmental agency
or body or otherwise which, if determined adversely to the Company, could result
in a Material Adverse Effect.  There are no statutes, rules, regulations, 
agreements, contracts, leases or documents that are required to be described in
the Prospectus, or to be filed as exhibits to the Registration Statement by the
Act or by the Rules and Regulations that have not been accurately and completely
described in the Prospectus or filed as exhibits to the Registration Statement.
    

                 (e)      All outstanding shares of capital stock of the
Company have been duly authorized and validly issued and are fully paid and
nonassessable, have been issued in compliance with all federal and state
securities laws, were not issued in violation of





                                       5
<PAGE>   6
   
any preemptive right, resale right, right of first refusal or similar right.
The authorized and outstanding capital stock of the Company conforms to the
description thereof contained in the Registration Statement, the Offering 
Memorandum and the Prospectus (and such description correctly states the
substance of the provisions of the instruments defining the capital stock of the
Company).  The Shares have been duly authorized for issuance and sale to the
Underwriters pursuant to this Agreement and, when issued and delivered by the
Company against payment therefor in accordance with the terms of this Agreement,
will be duly and validly issued and fully paid and nonassessable.  Except as set
forth in the Prospectus, no preemptive right, co-sale right, right of first
refusal or other similar rights of securityholders exists with respect to any of
the Shares or the issue and sale thereof other than those that have been
expressly waived prior to the date hereof.  No holder of securities of the
Company has the right to cause the Company to include such holder's securities
in the Registration Statement.  No further approval or authorization of any
security holder, the Board of Directors or any duly appointed committee thereof
or others is required for the issuance and sale or transfer of the Shares,
except as may be required under the Act, the Exchange Act or under state
securities or Blue Sky laws.  Except as disclosed in or contemplated by the
Prospectus, the Offering Memorandum and the financial statements of the 
Company, and the related notes thereto included in the Prospectus and the
Offering Memorandum, the Company does not have outstanding any options or
warrants to purchase, or any preemptive rights or other rights to subscribe for
or to purchase, any securities or obligations convertible into, or any contracts
or commitments to issue or sell, shares of its capital stock or any such
options, rights, convertible securities or obligations.  The description of the
Company's stock option and other plans or arrangements, and the options or other
rights granted and exercised thereunder, set forth in the Prospectus and the
Offering Memorandum accurately and fairly presents the information required to
be shown with respect to such plans, arrangements, options and rights.
    

   
                 (f)      KPMG Peat Marwick LLP (the "Accountants") who have
examined the financial statements, together with the related schedules and
notes, of the Company filed with the Commission as a part of the Registration
Statement, which are included in the Prospectus, are independent public
accountants within the meaning of the Act and the Rules and Regulations.  The
financial statements of the Company, together with the related schedules and
notes, forming part of the Registration Statement, the Offering Memorandum and 
the Prospectus, fairly present the financial position and the results of
operations of the Company at the respective dates and for the respective periods
    





                                       6

to which they apply.  All financial statements, together with the related
schedules and notes, filed with the Commission as part of the Registration
Statement have been prepared in accordance with generally accepted accounting
principles as in effect in the United States consistently applied throughout
the periods involved except as may be otherwise stated in the Registration

have been compiled on a basis consistent with the financial statements
presented therein.  No other financial statements or schedules are required by
the Act or the Rules and Regulations to be included in the Registration
Statement.

   
                 (g)      Subsequent to the respective dates as of which

business, operations, properties, assets, conditions (financial or otherwise),
results of operations or prospects of the Company and its Subsidiaries taken as
a whole, whether or not occurring in the ordinary course of business (a
"Material Adverse Change"), or any development involving, or which is likely to
cause, a Material Adverse Change, (ii) any transaction which is material to the
Company or its Subsidiaries, other than in the ordinary course of business,
(iii) any obligation, direct or contingent, which is material to the Company and
its Subsidiaries taken as a whole, incurred by the Company or its Subsidiaries,

restatement of the Company's Articles of Incorporation and Bylaws, (iii) the
conversion of all of the Company's outstanding Preferred Stock into Common Stock
and (iv) the effectiveness of the Company's 24 to 1 reverse stock split, in the
case of items (ii) through (iv) as set forth in and contemplated by the
Registration Statement, or (v) any dividend or distribution of any kind
declared, paid or made on the capital stock of the Company.  Neither the Company
nor its Subsidiaries has any material contingent obligation or liability which
is not disclosed in the Registration Statement.
    

   
                 (h)      (i) the Company and each Subsidiary have good and
marketable title to all material properties and assets described in the
Prospectus and the Offering Memorandum as owned by them, free and clear of any
pledge, lien, security interest, charge,  encumbrance, claim, equitable interest
or restriction, except those reflected in the financial statements or Prospectus
or which are not material in amount, (ii) the agreements to which the Company or
any Subsidiary is a party described in the Prospectus and the Offering
Memorandum are valid
    





                                       7

agreements, and, to the Company's knowledge after due inquiry, are enforceable
against the other contracting party or parties thereto in accordance with their
terms except as enforcement may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws relating to or affecting
creditors' rights generally or by general equitable principles and neither the
Company nor any subsidiary nor any other party thereto is in material breach or
default under any of such agreements and (iii) the Company and each Subsidiary
have valid and enforceable leases for the properties described in the Prospectus
and the Offering Memorandum as leased by it, and such leases conform in all
material respects to the description thereof, if any, set forth in the
Registration Statement.
    

   
                 (i)      The Company and each Subsidiary now hold and at the
Closing Date and any later Option Closing Date, as the case may be, will hold,
all licenses, certificates, approvals and permits from all state, United States,
foreign and other regulatory authorities, including but not limited to the
United States Federal Communications Commission (the "FCC") and any foreign
regulatory authorities performing functions similar to those performed by the
FCC, that are material to the conduct of the business of the Company (as such
business is currently conducted), all of which are valid and in full force and
effect (and there is no proceeding pending or, to the knowledge of the Company,
threatened which may cause any such license, certificate, approval or permit to
be withdrawn, cancelled, suspended or not renewed). Neither the Company nor any
Subsidiary is in violation of its certificate of incorporation or bylaws or in
default in the performance or observance of any obligation, agreement, covenant
or condition contained in any bond, debenture, note or other evidence of
indebtedness or in any contract, indenture, mortgage, loan agreement, joint
venture or other agreement or instrument to which it is a party or by which it
or any of its properties are bound, or in violation of any law, order, rule,
regulation, writ, injunction or decree of any court or governmental agency or
body, including, but not limited to, the FCC.  Neither the Company nor any
subsidiary is a party to any legal and governmental proceedings by or before the
FCC or any foreign, state or local government body exercising comparable
authority or to any material litigation. The descriptions contained in the
Registration Statement and the Prospectus of the laws, rules and regulations
applicable to the Company's products and their use as presently used are true,
complete and accurate in all material respects. 
    

                (j)      The Company and each Subsidiary have filed all
necessary federal, state and foreign income,





                                       8

franchise and other tax returns and has paid all taxes shown thereon as due,
and the Company has no knowledge of any tax deficiency which has been or might
be asserted against the Company or any Subsidiary.  All material tax
liabilities are adequately provided for within the financial statements of the
Company.

                 (k)      The Company and its Subsidiaries maintain insurance
of the types and in the amounts adequate for their business and consistent with
insurance coverage maintained by similar companies in similar businesses,
including, but not limited to, insurance covering product liability and real
and personal property owned or leased against theft, damage, destruction, acts
of vandalism and all other risks customarily insured against, all of which
insurance is in full force and effect.

                 (l)      Neither the Company nor its Subsidiaries are involved
in any labor dispute or disturbance nor, to the knowledge of the Company, is
any such dispute or disturbance threatened.

   
                 (m)      Except as described in the Prospectus and the 
Offering Memorandum, the Company and each Subsidiary own or possess adequate
licenses or other rights to use all patents, patent applications, trademarks,

franchises, and other material intangible property and assets (collectively,
"Intellectual Property") necessary to the conduct of their businesses as
conducted and as proposed to be conducted as described in the Prospectus and the
Offering Memorandum. The Company has no knowledge of any facts which would
preclude it from having rights to its patent applications referenced in the
Prospectus and the Offering Memorandum.  The Company has no knowledge that it or
any Subsidiary lacks or will be unable to obtain any rights or licenses to use
any of the Intellectual Property necessary to conduct the business now conducted
or proposed to be conducted by it as described in the Prospectus and the
Offering Memorandum, except as described in the Prospectus and the Offering
Memorandum.  The Prospectus and the Offering Memorandum fairly and accurately
describe the Company's rights with respect to the Intellectual Property.  The
Company has not received any notice of infringement or of conflict with rights
or claims of others with respect to any Intellectual Property.  The Company is
not aware of any patents of others which are infringed upon by potential
products or processes referred to in the Prospectus and the Offering Memorandum
in such a manner as to materially and adversely affect the Company and its
Subsidiaries taken as a whole, except as described in the Prospectus and the
Offering Memorandum.

constitute, the stabilization or manipulation of the price of sale or resale of
the Shares.

                (x)      Simultaneously with the purchase of the Firm Shares by
the Underwriters hereunder, the Company's Articles of Incorporation and By-Laws
will be amended and restated to be in the form attached to the Registration
Statement as Exhibits     and    , respectively; the Company's Common Stock will
be split 1:24; each outstanding share of the Company's Preferred Stock will be
converted automatically into one share of Common Stock (after giving effect to
the reverse split); each outstanding warrant to purchase Preferred Stock of the
Company will be converted into a warrant to purchase an equal number of shares
of Common Stock; and with the result that the Company's capitalization before
giving effect to the issuance of the Firm Shares will be as set forth on Exhibit
__ hereto. All necessary corporate and other proceedings, including, without
limitation, all necessary approvals by the Company's shareholders and Board of
Directors and all other action and consents and approvals requisite to
effectuate the foregoing have been duly taken and completed other than the
filing of the Company's amended and restated Articles of Incorporation with the
Secretary of State of the State of Washington, which shall be filed prior to the
Closing and be effective simultaneously with the purchase of the Firm Shares by
the Underwriters hereunder.
    


         3.      PURCHASE OF THE SHARES BY THE UNDERWRITERS.

                 (a)      On the basis of the representations and warranties
and subject to the terms and conditions herein set forth, the Company agrees to
issue and sell the Firm Shares to the several Underwriters, and each of the
Underwriters agrees to purchase from the Company the respective aggregate
number of Firm Shares set forth opposite its name on Schedule A, plus such
additional number of Firm Shares which such Underwriter may become obligated to
purchase pursuant to Section 3(b) hereof.  The price at which such Firm Shares
shall be sold by the Company and purchased by the several Underwriters shall be
$_____ per share.  In making this Agreement, each Underwriter is contracting
severally and not jointly; except as provided in paragraphs (b) and (c) of this
Section 3, the agreement of each Underwriter is to purchase only the respective
number of Firm Shares specified on Schedule A.

                 (b)      If for any reason one or more of the Underwriters
shall fail or refuse (otherwise than for a reason sufficient to justify the
termination of this Agreement under the provisions of Section 10 hereof) to
purchase and pay for the number of Shares agreed to be purchased by such
Underwriter or Underwriters, the non-defaulting Underwriters shall have the
right within twenty-four (24) hours after such default to purchase, or procure
one or more other Underwriters to purchase, in such proportions as may be
agreed upon between you and such purchasing Underwriter or Underwriters and
upon the terms herein set forth, all or any part of the Shares which such
defaulting Underwriter or Underwriters agreed to purchase. If the
non-defaulting Underwriters fail so to make such arrangements with respect to
all such Shares and portion, the number of Shares which each non-defaulting
Underwriter is otherwise obligated to purchase under this





                                       12
<PAGE>   13
   
Agreement shall be automatically increased on a pro rata basis (as adjusted by
you in such manner as you deem advisable to avoid fractional shares) to absorb
the remaining Shares and portion which the defaulting Underwriter or
Underwriters agreed to purchase; provided, however, that the non-defaulting
Underwriters shall not be obligated to purchase the Shares and portion which
the defaulting Underwriter or Underwriters agreed to purchase if the aggregate
number of such Shares exceeds 10% of the total number of Shares which all
Underwriters agreed to purchase hereunder.  If the total number of Shares which
the defaulting Underwriter or Underwriters agreed to purchase shall not be
purchased or absorbed in accordance with the two preceding sentences, the
Company shall have the right, within twenty-four (24) hours next succeeding the
24-hour period referred to above, to make arrangements with other underwriters
or purchasers reasonably satisfactory to you for purchase of such Shares and
portion on the terms herein set forth.  In any such case, either you or the
Company shall have the right to postpone the Closing Date determined as
provided in Section 5 hereof for not more than seven business days after the
date originally fixed as the Closing Date pursuant to said Section 5 in order
that any necessary changes in the Registration Statement, the Offering
Memorandum, the Prospectus or any other documents or arrangements may be made.
If the aggregate number of Shares which the defaulting Underwriter or
Underwriters agreed to purchase exceeds 10% of the total number of Shares which
all Underwriters agreed to purchase hereunder, and if neither the non-defaulting
Underwriters nor the Company shall make arrangements within the 24-hour periods
stated above for the purchase of all the Shares which the defaulting Underwriter
or Underwriters agreed to purchase hereunder, this Agreement shall be terminated
without further act or deed and without any liability on the part of the Company
to any non-defaulting Underwriter and without any liability on the part of any
non-defaulting Underwriter to the Company.  Nothing in this paragraph (b), and
no action taken hereunder, shall relieve any defaulting Underwriter from
liability in respect of any default of such Underwriter under this Agreement.
    

                 (c)      On the basis of the representations, warranties and
covenants herein contained, and subject to the terms and conditions herein set
forth, the Company grants an option to the several Underwriters to purchase all
or any portion of the Option Shares from the Company at the same price per
share as the Underwriters shall pay for the Firm Shares.  Said option may be
exercised only to cover over- allotments in the sale of the Firm Shares by the
Underwriters and may be exercised in whole or in





                                       13
<PAGE>   14
part at any time (but not more than once) on or before the 30th day after the
date of this Agreement upon written or telegraphic notice by you to the Company
setting forth the aggregate number of shares of the Option Shares as to which
the several Underwriters are exercising the option.  Delivery of certificates
for the shares of Option Shares, and payment therefor, shall be made as
provided in Section 5 hereof.  Each Underwriter will purchase such percentage
of the Option Shares as is equal to the percentage of Firm Shares that such
Underwriter is purchasing, the exact number of shares to be adjusted by you in
such manner as you deem advisable to avoid fractional shares.

         4.      OFFERING BY UNDERWRITERS.

   
                 (a)      The terms of the initial public offering of the Shares
in the United States by the Underwriters shall be as set forth in the
Prospectus.  The terms of the private placement of the Shares in Canada by the
Underwriters shall be as set forth in the Offering Memorandum. The Underwriters
may from time to time change the public offering and private placement prices
after the closing of the initial public offering and the private placement,
respectively, and increase or decrease the concessions and discounts to dealers
as they may determine.
    

   
                 (b)      You, on behalf of the Underwriters, represent and
warrant that (i) the information set forth in the last paragraph on the front
cover page and paragraph __ under the caption "Underwriting" in the Registration
Statement, the Offering Memorandum, any Preliminary Prospectus and the
Prospectus relating to the Shares (insofar as such information relates to the
Underwriters) constitutes the only information furnished by the Underwriters to
the Company for inclusion in the Registration Statement, the Offering
Memorandum, any Preliminary Prospectus, and the Prospectus, and that the
statements made therein are correct and do not omit to state any material fact
required to be stated therein or necessary to make the statements made therein
in light of the circumstances under which they were made not misleading, and
(ii) the Underwriters have not distributed and will not distribute prior to the
Closing Date or on any Option Closing Date, as the case may be, any offering
material in connection with the offering and sale of the shares other than the
Preliminary Prospectus, the Prospectus, the Registration Statement, the Offering
Memorandum, and other materials permitted by the Act and applicable Canadian
securities law.
    

         5.      DELIVERY OF AND PAYMENT FOR THE SHARES.

                 (a)      Delivery of certificates for the Firm Shares and the
Option Shares (if the option granted pursuant to Section 3(c) hereof shall have
been exercised not later than 1:00 p.m., New York time, on the date at least
two business days preceding the





                                       14
<PAGE>   15
Closing Date), and payment therefor, shall be made at the offices of UBS
Securities LLC, 299 Park Avenue, New York, New York 10171 at 9:00 a.m.  New
York time, on the fourth business day after the date of this  Agreement, or at
such time on such other day, not later than seven full business days after such
fourth business day, as shall be agreed upon in writing by the Company and you
(the "Closing Date").

                 (b)      If the option granted pursuant to Section 3(c) hereof
shall be exercised after 1:00 p.m., New York time, on the date two business
days preceding the Closing Date, and on or before the 30th day after the date
of this Agreement, delivery of certificates for the Option Shares, and payment
therefor, shall be made at the offices of UBS Securities LLC, 299 Park Avenue,
New York, New York 10171 at 9:00 a.m., New York time, on the third business day
after the exercise of such option.

                 (c)      Payment for the Shares purchased from the Company
shall be made to the Company or its order, by [either a same day funds check or
Federal Funds wire transfer] [New York Clearing House Funds].  Such payment
shall be made upon delivery of certificates for the Shares to you for the
respective accounts of the several Underwriters against receipt therefor signed
by you. Certificates for the Shares to be delivered to you shall be registered
in such name or names and shall be in such denominations as you may request at
least three business days before the Closing Date, in the case of Firm Shares,
and at least two business days prior to the Option Closing Date, in the case of
the Option Shares.  Such certificates will be made available to the
Underwriters for inspection, checking and packaging at a location in New York,
New York, designated by the Underwriters not less than one full business day
prior to the Closing Date or, in the case of the Option Shares, by 3:00 p.m.,
New York time, on the business day preceding the Option Closing Date.

         It is understood that you, individually and not on behalf of the
Underwriters, may (but shall not be obligated to) make payment to the Company
for shares to be purchased by any Underwriter whose check shall not have been
received by you on the Closing Date or any later Option Closing Date.  Any such
payment by you shall not relieve such Underwriter from any of its obligations
hereunder.

         6.      FURTHER AGREEMENTS OF THE COMPANY.  The Company covenants and
                 agrees as follows:





                                       15
<PAGE>   16
                 (a)      The Company will use its best efforts to cause the
Registration Statement and any amendment thereof, if not effective at the time
and date that this Agreement is executed and delivered by the parties hereto,
to become effective as promptly as possible; it will notify you, promptly after
it shall receive notice thereof, of the time when the Registration Statement or
any subsequent amendment to the Registration Statement has become effective or
any supplement to the Prospectus has been filed.  If the Company omitted
information from the Registration Statement at the time it was originally
declared effective in reliance upon Rule 430A(a), the Company will provide
evidence satisfactory to you that the Prospectus contains such information and
has been filed, within the time period prescribed, with the Commission pursuant
to subparagraph (1) or (4) of Rule 424(b) of the Rules and Regulations or as
part of a post-effective amendment to such Registration Statement as originally
declared effective which is declared effective by the Commission.  If for any
reason the filing of the final form of Prospectus is required under Rule
424(b)(3) of the Rules and Regulations, it will provide evidence satisfactory
to you that the Prospectus contains such information and has been filed with
the Commission within the time period prescribed.  The Company will notify you
promptly of any request by the Commission for the amending or supplementing of
the Registration Statement or the Prospectus or for additional information.
Promptly upon your request, it will prepare and file with the Commission any
amendments or supplements to the Registration Statement or Prospectus which, in
the reasonable opinion of counsel to the several Underwriters ("Underwriters'
Counsel"), may be necessary or advisable in connection with the distribution of
the Shares by the Underwriters.  The Company will promptly prepare and file
with the Commission, and promptly notify you of the filing of, any amendments
or supplements to the Registration Statement or Prospectus which may be
necessary to correct any statements or omissions, if, at any time when a
prospectus relating to the Shares is required to be delivered under the Act,
any event shall have occurred as a result of which the Prospectus or any other
prospectus relating to the Shares as then in effect would include an untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein, in light of the circumstances under which they
were made, not misleading. In case any Underwriter is required to deliver a
prospectus within the nine-month period referred to in Section 10(a)(3) of the
Act in connection with the sale of the Shares, the Company will prepare
promptly upon request, but at the expense of such Underwriter, such amendment
or amendments to the Registration Statement and such prospectus or prospectuses
as may





                                       16
<PAGE>   17
be necessary to permit compliance with the requirements of Section 10(a)(3) of
the Act.  The Company will file no amendment or supplement to the Registration
Statement or Prospectus that shall not previously have been submitted to you a
reasonable time prior to the proposed filing thereof or to which you shall
reasonably object in writing or which is not in compliance with the Act and
Rules and Regulations or the provisions of this Agreement.

                 (b)      The Company will advise you, promptly after it shall
receive notice or obtain knowledge thereof of the issuance of any stop order by
the Commission suspending the effectiveness of the Registration Statement or
the use of the Prospectus or of the initiation or threat of any proceeding for
that purpose; and it will promptly use its best efforts to prevent the issuance
of any such stop order or to obtain its withdrawal at the earliest possible
moment if such stop order should be issued.

                 (c)      The Company will cooperate with you in endeavoring to
qualify the Shares for offering and sale under the securities laws of such
jurisdictions as you may designate and to continue such qualifications in
effect for so long as may be required for purposes of the distribution of the
Shares, except that the Company shall not be required in connection therewith
or as a condition thereof to qualify as a foreign corporation, or to execute a
general consent to service of process in any jurisdiction, or to make any
undertaking with respect to the conduct of its business.  In each jurisdiction
in which the Shares shall have been qualified, the Company will make and file
such statements, reports and other documents in each year as are or may be
reasonably required by the laws of such jurisdictions so as to continue such
qualifications in effect for so long a period as you may reasonably request for
distribution of the Shares, or as otherwise may be required by law.

   
                 (d)      The Company will furnish to you, as soon as
available, copies of the Registration Statement (three of which will be signed
and which will include all exhibits), each Preliminary Prospectus, the
Prospectus, the Offering Memorandum and any amendments or supplements to such
documents, including any prospectus prepared to permit compliance with Section
10(a)(3) of the Act, all in such quantities as you may from time to time
reasonably request.
    

                 (e)      The Company will make generally available to its
stockholders as soon as practicable, but in any event not later than the 45th
day following the end of the fiscal quarter first occurring after the first
anniversary of the effective date of the





                                       17
<PAGE>   18
Registration Statement, an earnings statement (which will be in reasonable
detail but need not be audited) complying with the provisions of Section 11(a)
of the Act and Rule 158 of the Rules and Regulations and covering a
twelve-month period beginning after the effective date of the Registration
Statement, and will advise you in writing when such statement has been made
available.

                 (f)      During a period of five years after the date hereof,
the Company, as soon as practicable after the end of each respective period,
will furnish to its stockholders annual reports (including financial statements
audited by independent certified public accountants) and will furnish to its
stockholders unaudited quarterly reports of operations for each of the first
three quarters of the fiscal year, and will, upon request, furnish to you and
the other several Underwriters hereunder (i) concurrently with making such
reports available to its stockholders, statements of operations of the Company
for each of the first three quarters in the form made available to the
Company's stockholders; (ii) concurrently with the furnishing thereof to its
stockholders, a balance sheet of the Company as of the end of such fiscal year,
together with statements of operations, of stockholders' equity and of cash
flow of the Company for such fiscal year, accompanied by a copy of the
certificate or report thereon of nationally recognized independent certified
public accountants; (iii) concurrently with the furnishing of such reports to
its stockholders, copies of all reports (financial or other) mailed to
stockholders; (iv) as soon as they are available, copies of all reports and
financial statements furnished to or filed with the Commission, any securities
exchange or the NASDAQ National Market by the Company (except for documents for
which confidential treatment is requested); and (v) every material press
release and every material news item or article in respect of the Company or
its affairs which was generally released to stockholders or prepared for
general release by the Company. During such five-year period, if the Company
shall have any active subsidiaries, the foregoing financial statements shall be
on a consolidated basis to the extent that the accounts of the Company are
consolidated with any subsidiaries, and shall be accompanied by similar
financial statements for any significant subsidiary that is not so
consolidated.

                 (g)      Prior to or simultaneously with the execution and
delivery of this Agreement, the Company will obtain agreement from each
beneficial owner of the Company's Common Stock listed on Schedule B to this
Agreement providing that such person will not, for a period of 180 days after
the date of the Prospectus, without





                                       18
<PAGE>   19
the prior written consent of UBS Securities LLC, directly or indirectly, offer
to sell, sell, hypothecate, contract to sell, grant any option to purchase, or
otherwise dispose of, any shares of Common Stock beneficially owned as of the
date such lockup agreement is executed (including, without limitation, shares
of Common Stock which may be deemed to be beneficially owned in accordance with
the Rules and Regulations and shares of Common Stock which may be issued upon
exercise of a stock option or warrant) or any securities convertible into or
exercisable or exchangeable for such Common Stock except as otherwise provided
in the pertinent executed Lock-Up Agreement.  Each such person or entity shall
also agree and consent to the entry of stop transfer instructions with the
Company's transfer agent against the transfer of shares of Common Stock held by
such person or entity, except in compliance with the foregoing restriction.

                 (h)      The Company shall not, during the 180 days following
the effective date of the Registration Statement, except with your prior
written consent as Representatives, file a registration statement covering any
of its shares of capital stock, except that one or more registration statements
on Form S-8 may be filed at any time following the effective date of the
Registration Statement.

                 (i)      The Company shall not, during the 180 days following
the effective date of the Registration Statement, except with your prior
written consent as Representatives, issue, sell, offer or agree to sell, grant,
distribute or otherwise dispose of, directly or indirectly, any shares of
Common Stock, or any options, rights or warrants with respect to shares of
Common Stock, or any securities convertible into or exchangeable for Common
Stock, other than (i) the sale of Shares hereunder, (ii) the grant of options
or the issuance of shares of Common Stock under the Company's stock option
plans or stock purchase plan, as the case may be, existing on the date hereof,
or (iii) the issuance of shares of Common Stock upon exercise of the currently
outstanding options or warrants described in the Registration Statement.

                 (j)      The Company will apply the net proceeds from the sale
of the Shares being sold by it in the manner set forth under the caption "Use
of Proceeds" in the Prospectus.

                 (k)      The Company will maintain a Transfer Agent and, if
necessary under the jurisdiction of incorporation of the Company,





                                       19
<PAGE>   20
a Registrar (which may be the same entity as the Transfer Agent) for its Common
Stock.

                 (l)      The Company will use its best efforts to maintain
listing of its shares of Common Stock on the NASDAQ National Market.

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

   
                 (n)      If at any time during the 180-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
reasonable 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 consult with you in good faith regarding the necessity of
disseminating a press release or other public statement responding to or
commenting on such rumor, publication or event and, if the Company in its
reasonable judgment determines that such a press release or other public
statement is appropriate, the substance of any press release or other public
statement.
    

         Any certificate signed by an officer of the Company and delivered to
the Representatives or to Underwriters' Counsel in connection with the
execution and delivery of this Agreement, the Closing and the Option Closing
hereunder shall be deemed a representation and warranty by the Company to each
Underwriter as to the matters covered thereby.

documents as it may have reasonably requested for the purpose of enabling it to
pass upon such matters.

   
                 (e)      You shall have received on the Closing Date and on
any later Option Closing Date, as the case may be, a letter from the
Accountants addressed to the Company and the Underwriters, dated the Closing
Date or such later Option Closing Date, as the case may be, confirming that it
is an independent certified public accountant with respect to the Company
within the meaning of the Act and the Rules and Regulations thereunder and
based upon the procedures described in its letter delivered to you concurrently
with the execution of this Agreement (herein called the "Original Letter"), but
carried out to a date not more than three days prior to the Closing Date or any
such later Option Closing Date, as the case may be, (i) confirming that the
statements and conclusions set forth in the Original Letter are accurate as of
the Closing Date or such later Option Closing Date, as the case may be; and
(ii) setting forth any revisions and additions to the statements and
conclusions set forth in the Original Letter that are necessary to reflect any
changes in the facts described in the Original Letter since the date of such
letter, or to reflect the availability of more recent financial statements,
data or information.  The letter shall not disclose any change, or any
development involving a prospective change, in or affecting the business or
properties of the Company which, in your reasonable judgment, makes it
impracticable or inadvisable to proceed with the public offering of the Shares
as contemplated by the Prospectus.  In addition, you shall have received from
the Accountants a letter addressed to the Company and made available to you for
the use of the Underwriters stating that its review of the Company's system of
internal accounting controls, to the extent it deemed necessary in establishing
the scope of its latest examination of the Company's financial statements, did
not disclose any weaknesses in internal controls that it considered to be
material weaknesses.  All such letters shall be in a form satisfactory to the 
Representatives and their counsel in their reasonable opinion.
    

                 (f)      You shall have received on the Closing Date and on
any later Option Closing Date, as the case may be, a certificate of the
President and the Chief Financial Officer of the Company, dated the Closing
Date or such later date, to the effect that as of such date (and you shall be
satisfied that as of such date):

                          (i)     The representations and warranties of the
                 Company in this Agreement are true and correct, as if made on
                 and as of the Closing Date or any later Option





                                       23
<PAGE>   24
   
                 Closing Date, as the case may be; and the Company has complied
                 with all of the agreements and satisfied all of the conditions
                 on its part to be performed or satisfied at or prior to the
                 Closing Date or any later Option Closing Date, as the case may
                 be in all material respects;
    

                          (ii)    The Registration Statement has become
                 effective under the Act and no stop order suspending the
                 effectiveness of the Registration Statement or preventing or
                 suspending the use of the Prospectus has been issued, and no
                 proceedings for that purpose have been instituted or are
                 pending or, to the best of their knowledge, threatened under
                 the Act;

   
                          (iii) They have carefully reviewed the Registration
                 Statement, the Offering Memorandum, and the Prospectus; and,
                 when the Registration Statement became effective and at all
                 times subsequent thereto up to the delivery of such
                 certificate, the Registration Statement and the Prospectus and
                 any amendments or supplements thereto contained all statements
                 and information required to be included therein or necessary to
                 make the statements therein not misleading; and when the
                 Registration Statement became effective, and at all times
                 subsequent thereto up to the delivery of such certificate, none
                 of the Registration Statement, the Prospectus or the Offering
                 Memorandum, or any amendment or supplement thereto included any
                 untrue statement of a material fact or omitted to state any
                 material fact required to be stated therein or necessary to
                 make the statements therein not misleading; and, since the
                 effective date of the Registration Statement, there has
                 occurred no event required to be set forth in an amended or
                 supplemented Prospectus or Offering Memorandum that has not
                 been so set forth; and
    

   
                          (iv)    Subsequent to the respective dates as of which
                 information is given in the Registration Statement, the
                 Offering Memorandum and the Prospectus, there has not been
                 (A) any Material Adverse Change or any prospective Material
                 Adverse Change, (B) any transaction which is material to the
                 Company and its Subsidiaries taken as a whole, not in the
                 ordinary course of business, (C) any obligation, direct or
                 contingent, incurred by the Company or its Subsidiaries, which
                 is material to the Company and its Subsidiaries taken as a
                 whole, (D) any change in the capital stock or outstanding
                 indebtedness of the Company or its Subsidiaries or in
    





                                       24
<PAGE>   25
                 the outstanding indebtedness of the Company which is material
                 to the Company and its Subsidiaries taken as a whole or (E)
                 any dividend or distribution of any kind declared, paid or
                 made on the capital stock of the Company.

                 (g)      The Company shall have furnished to you such further
certificates and documents as you shall reasonably request as to the accuracy
of the representations and warranties of the Company herein, as to the
performance by the Company of its obligations hereunder and as to the other
conditions concurrent and precedent to the obligations of the Underwriters
hereunder.

   
    

         All such opinions, certificates, letters and documents will be in
compliance with the provisions hereof only if they are reasonably satisfactory
to Underwriters' Counsel.  The Company will furnish you with such number of
conformed copies of such opinions, certificates, letters and documents as you
shall reasonably request.

         9.      INDEMNIFICATION AND CONTRIBUTION.

   
                 (a)      Subject to the provisions of paragraph (f) below, the
Company agrees to indemnify and hold harmless each Underwriter and each person
(including each partner or officer thereof) who controls any Underwriter within
the meaning of Section 15 of the Act from and against any and all losses,
claims, damages or liabilities, joint or several, to which such indemnified
parties or any of them may become subject under the Act, the Exchange Act, or
the common law or otherwise, and the Company agrees to reimburse each such
Underwriter and controlling person for any legal or other out-of-pocket
expenses (including, except as otherwise hereinafter provided, reasonable fees
and disbursements of counsel) incurred by the respective indemnified parties in
connection with defending against any such losses, claims, damages or
liabilities or in connection with any investigation or inquiry of, or other
proceeding which may be brought against, the respective indemnified parties, in
each case arising out of or based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement
(including the Prospectus as part thereof and any 462(b) registration
statement) or in the Offering Memorandum or any post-effective amendment 
thereto (including any
    





                                       25
<PAGE>   26
   
462(b) registration statement), or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, or (ii) any untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus or
the Prospectus (as amended or as supplemented if the Company shall have filed
with the Commission any amendment thereof or supplement thereto), or in the
Offering Memorandum or the omission or alleged omission to state therein a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading; provided, however,
that (1) the indemnity agreements of the Company contained in this paragraph (a)
shall not apply to any such losses, claims, damages, liabilities or expenses if
such statement or omission is contained in the section of the Prospectus
entitled "Underwriting" (except for the ____ paragraph thereof) or the last
paragraph of text on the cover page of the Prospectus, and (2) the indemnity
agreement contained in this paragraph (a) with respect to any Preliminary
Prospectus or Offering Memorandum shall not inure to the benefit of any
Underwriter from whom the person asserting any such losses, claims, damages,
liabilities or expenses purchased the Shares which are the subject thereof (or
to the benefit of any person controlling such Underwriter) if at or prior to the
written confirmation of the sale of such Shares a copy of the Prospectus (or the
Prospectus as amended or supplemented or in the case of purchasers resident in
Ontario, Canada, the revised Offering Memorandum) was not sent or delivered to
such person and the untrue statement or omission of a material fact contained in
such Preliminary Prospectus was corrected in the Prospectus (or the Prospectus
as amended or supplemented or in the case of purchasers resident in Ontario,
Canada, the revised Offering Memorandum) unless the failure is the result of
noncompliance by the Company with paragraph (a) of Section 6 hereof.  The
indemnity agreements of the Company contained in this paragraph (a) and the
representations and warranties of the Company contained in Section 2 hereof
shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any indemnified party and shall survive
the delivery of any payment for the Shares.
    

                 (b)      Each Underwriter severally agrees to indemnify and
hold harmless the Company, each of its executive officers, each of its
directors, each other Underwriter and each person (including each partner or
officer thereof) who controls the Company or any such other Underwriter within
the meaning of Section 15 of the Act, from and against any and all losses,
claims, damages or liabilities, joint or several, to which such indemnified
parties or any of them may become subject under the Act, the Exchange Act, or
the common law or otherwise and to reimburse each of them for any legal or
other expenses including, except as otherwise





                                       26
<PAGE>   27
   
hereinafter provided, reasonable fees and disbursements of counsel) incurred by
the respective indemnified parties in connection with defending against any such
losses, claims, damages or liabilities or in connection with any investigation
or inquiry of, or other proceeding which may be brought against, the respective
indemnified parties, in each case arising out of or based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (including the Prospectus as part thereof and any Rule
462(b) registration statement), or in the Offering Memorandum, or any
post-effective amendment thereto (including any 462(b) registration statement)
or the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading or
(ii) any untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus or the Prospectus (as amended or as
supplemented if the Company shall have filed with the Commission any amendment
thereof or supplement thereto), or in the Offering Memorandum, or the omission
or alleged omission to state therein a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading; provided, however, that in the cases of clauses (i) and
(ii) above, such statement or omission is contained in the Section of the
Prospectus entitled "Underwriting" (except for the ____ paragraph thereof) or
the last paragraph on the cover page of the Prospectus.  The indemnity agreement
of each Underwriter contained in this paragraph (b) shall remain operative and
in full force and effect regardless of any investigation made by or on behalf of
any indemnified party and shall survive the delivery of and payment for the
Shares.
    

                 (c)      Each party indemnified under the provision of
paragraphs (a) and (b) of this Section 9 agrees that, upon the service of a
summons or other initial legal process upon it in any action or suit instituted
against it or upon its receipt of written notification of the commencement of
any investigation or inquiry of, or proceeding against it, in respect of which
indemnity may be sought on account of any indemnity agreement contained in such
paragraphs, it will promptly give written notice (a "Notice") of such service
or notification to the party or parties from whom indemnification may be sought
hereunder.  No indemnification provided for in such paragraphs shall be
available to any party who shall fail so to give the Notice if the party to
whom such Notice was not given was unaware of the action, suit, investigation,
inquiry or proceeding to which the Notice would have related and was prejudiced
by the failure to give the Notice, but the omission so to notify such
indemnifying party or parties





                                       27
<PAGE>   28
of any such service or notification shall not relieve such indemnifying party
or parties from any liability which it or they may have to the indemnified
party for contribution or otherwise than on account of such indemnity
agreement.  Any indemnifying party shall be entitled at its own expense to
participate in the defense of any action, suit or proceeding against, or
investigation or inquiry of, an indemnified party.  Any indemnifying party
shall be entitled, if it so elects within a reasonable time after receipt of
the Notice by giving written notice (the "Notice of Defense") to the
indemnified party, to assume (alone or in conjunction with any other
indemnifying party or parties) the entire defense of such action, suit,
investigation, inquiry or proceeding, in which event such defense shall be
conducted, at the expense of the indemnifying party or parties, by counsel
chosen by such indemnifying party or parties and reasonably satisfactory to the
indemnified party or parties; provided, however, that (i) if the indemnified
party or parties reasonably determine that there may be a conflict between the
positions of the indemnifying party or parties and of the indemnified party or
parties in conducting the defense of such action, suit, investigation, inquiry
or proceeding or that there may be legal defenses available to such indemnified
party or parties different from or in addition to those available to the
indemnifying party or parties, then counsel for the indemnified party or
parties shall be entitled to conduct the defense to the extent reasonably
determined by such counsel to be necessary to protect the interests of the
indemnified party or parties and (ii) in any event, the indemnified party or
parties shall be entitled, at its or their own expense to have counsel chosen
by such indemnified party or parties participate in, but not conduct, the
defense.  It is understood that the indemnifying parties shall not, in respect
of the legal defenses of any indemnified party in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for (a)
the fees and expenses of more than one separate firm (in addition to any local
counsel) for all of the Underwriters and each person, if any, who controls any
Underwriter within the meaning of Section 15 of the Act, and (b) the fees and
expenses of more than one separate firm (in addition to any local counsel) for
the Company, its directors, its officers who sign the Registration Statement
and each person, if any, who controls the Company within the meaning of Section
15 of the Act.  If, within a reasonable time after receipt of the Notice, an
indemnifying party gives a Notice of Defense and the counsel chosen by the
indemnifying party or parties is reasonably satisfactory to the indemnified
party or parties, the indemnifying party or parties will not be liable under
paragraphs (a) through





                                       28
<PAGE>   29
(c) of this Section 9 for any legal or other expenses subsequently incurred by
the indemnified party or parties in connection with the defense of the action,
suit, investigation, inquiry or proceeding, except that (A) the indemnifying
party or parties shall bear the legal and other expenses incurred in connection
with the conduct of the defense as referred to in clause (i) of the proviso to
the preceding sentence and (B) the indemnifying party or parties shall bear
such other expenses as it or they have authorized to be incurred by the
indemnified party or parties.  If, within a reasonable time after receipt of
the Notice, no Notice of Defense has been given, the indemnifying party or
parties shall be responsible for any legal or other expenses incurred by the
indemnified party or parties in connection with the defense of the action,
suit, investigation, inquiry or proceeding.  The indemnifying party or parties
shall not be liable for any settlement of any proceeding effected without its
or their written consent, provided such consent has not been unreasonably
withheld.

                 (d)      If the indemnification provided for in this Section 9
is unavailable or insufficient to hold harmless an indemnified party under
paragraph (a) or (b) of this Section 9, then each indemnifying party shall, in
lieu of indemnifying such indemnified party, contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in paragraph (a) or (b) of this Section 9 (i) in such
proportion as is appropriate to reflect the relative benefits received by each
indemnifying party from the offering of the Shares or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of each indemnifying party
in connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, or actions in respect thereof, as well as any
other relevant equitable considerations.  The relative benefits received by the
Company, on the one hand, and the Underwriters, on the other, shall be deemed
to be in the same respective proportions as the total net proceeds from the
offering of the Shares received by the Company and the total underwriting
discount received by the Underwriters, as set forth in the table on the cover
page of the Prospectus, bear to the aggregate public offering price of the
Shares.  Relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or
the omission or alleged omission to state a material fact relates to
information supplied by each indemnifying





                                       29
<PAGE>   30
party and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission.

                 The parties agree that it would not be just and equitable if
contributions pursuant to this paragraph (d) were to be determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take into account
the equitable considerations referred to in the first sentence of this
paragraph (d).  The amount paid by an indemnified party as a result of the
losses, claims, damages or liabilities, or actions in respect thereof, referred
to in the first sentence of this paragraph (d) shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigation, preparation to defend or defense against any
action or claim which is the subject of this paragraph (d).  Notwithstanding
the provisions of this paragraph (d), no Underwriter shall be required to
contribute any amount in excess of the underwriting discount applicable to the
Shares purchased by such Underwriter.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations in this paragraph (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

                 Each party entitled to contribution agrees that upon the
service of a summons or other initial legal process upon it in any action
instituted against it in respect of which contribution may be sought, it will
promptly give written notice of such service to the party or parties from whom
contribution may be sought, but the omission so to notify such party or parties
of any such service shall not relieve the party from whom contribution may be
sought from any obligation it may have hereunder or otherwise (except as
specifically provided in paragraph (c) of this Section 9).

                 (e)      The Company will not, without the prior written
consent of each Underwriter, settle or compromise or consent to the entry of
any judgment in any pending or threatened claim, action, suit or proceeding in
respect of which indemnification may be sought hereunder (whether or not such
Underwriter or any person who controls such Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act is a party to such





                                       30
<PAGE>   31
claim, action, suit or proceeding) unless such settlement, compromise or
consent includes an unconditional release of such Underwriter and each such
controlling person from all liability arising out of such claim, action, suit
or proceeding.

   
                 (f)      The 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 9 and are fully informed regarding said
provisions.  They further acknowledge that the provisions of this Section 9
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 and Prospectus as required by the Act and
the Exchange Act or in the Offering Memorandum as required by Canadian
securities law.
    

         10.     TERMINATION.  This Agreement may be terminated by you at any
time on or prior to the Closing Date or on or prior to any later Option Closing
Date, as the case may be, (i) if the Company shall have failed, refused or been
unable, at or prior to the Closing Date, or on or prior to any later Option
Closing Date, as the case may be, to perform any agreement on its part to be
performed, or because any other condition of the Underwriters' obligations
hereunder required to be fulfilled by the Company is not fulfilled, or (ii) if
trading on the New York Stock Exchange, the American Stock Exchange or the
NASDAQ National Market shall have been suspended, or minimum or maximum prices
for trading shall have been fixed, or maximum ranges for prices for securities
shall have been required on the New York Stock Exchange, the American Stock
Exchange or the NASDAQ National Market, by such trading exchanges or by order
of the Commission or any other governmental authority having jurisdiction, or
if a banking moratorium shall have been declared by federal or New York
authorities, or (iii) if the Company shall have sustained a loss by strike,
fire, flood, accident or other calamity of such character as to have a Material
Adverse Effect regardless of whether or not such loss shall have been insured,
or (iv) if there shall have been a material adverse change in the general
political or economic conditions or financial markets in the United States as
in the judgment of the  Representatives makes it inadvisable or impracticable
to proceed with the offering, sale and delivery of the Shares, or (v) if there
shall have occurred an outbreak or escalation of hostilities between the United
States and any foreign power or of any other insurrection or armed conflict
involving the United States or other national or international calamity,
hostilities or crisis or the declaration by the United





                                       31
<PAGE>   32
   
States of a national emergency which, in the judgment of the Representatives,
adversely affects the marketability of the Shares, or (vi) if since the
respective dates as of which information is given in the Registration Statement,
the Offering Memorandum and the Prospectus, there shall have occurred any
material adverse change or any development involving a prospective material
adverse change in or affecting the condition, financial or otherwise, of the
Company or the business affairs, management, or business prospects of the
Company, whether or not arising in the ordinary course of business, or (vii) if
any foreign, federal or state statute, regulation, rule or order of any court or
other governmental authority shall have been enacted, published, decreed or
otherwise promulgated which in the judgment of the Representatives materially
and adversely affects or will materially and adversely affect the business or
operations of the Company, or trading in the Common Stock shall have been
suspended, or (viii) there shall have occurred a material adverse decline in the
value of securities generally on the New York Stock Exchange, the American Stock
Exchange or the NASDAQ National Market or (ix) action shall be taken by any
foreign, federal, state or local government or agency in respect of its monetary
or fiscal affairs which, in the judgment of the Representatives, has a material
adverse effect on the securities markets in the United States.  If this
Agreement shall be terminated in accordance with this Section 10, there shall be
no liability of the Company to the Underwriters and no liability of the
Underwriters to the Company; provided, however, that in the event of any such
termination the Company agrees to indemnify and hold harmless the Underwriters
from all costs or expenses incident to the performance of the obligations of the
Company under this Agreement, including all costs and expenses referred to in
Section 7.
    

         If you elect to terminate this Agreement as provided in this Section
10, the Company shall be notified promptly by you by telephone, telecopy or
telegram, confirmed by letter.

         11.     REIMBURSEMENT OF CERTAIN EXPENSES.

                 (a)      In addition to their other obligations under Section
9 of this Agreement, the Company hereby agrees to reimburse on a quarterly
basis the Underwriters for all reasonable legal and other expenses incurred in
connection with investigating or defending any claim, action, investigation,
inquiry or other proceeding arising out of or based upon any statement or
omission, or any alleged statement or omission, described in paragraph (a) of
Section 9 of this Agreement, notwithstanding the absence of a





                                       32
<PAGE>   33
judicial determination as to the propriety and enforceability of the
obligations under this Section 11 and the possibility that such payments might
later be held to be improper; provided, however, that (i) to the extent any
such payment is ultimately held to be improper, the persons receiving such
payments shall promptly refund them and (ii) such persons shall provide to the
Company, upon request, reasonable assurances of their ability to effect any
refund, when and if due.

                 (b)      In addition to their other obligations under Section
9 of this Agreement, the Underwriters hereby agree to reimburse on a quarterly
basis the Company for all reasonable legal and other expenses incurred in
connection with investigating or defending any claim, action, investigation,
inquiry or other proceeding arising out of or based upon any statement or
omission, or any alleged statement or omission, described in paragraph (b) of
Section 9 of this Agreement, notwithstanding the absence of a judicial
determination as to the propriety and  enforceability of the obligations under
this Section 11 and the possibility that such payments might later be held to
be improper; provided, however, that (i) to the extent any such payment is
ultimately held to be improper, the Company shall promptly refund it and (ii)
the Company shall provide to the Underwriter, upon request, reasonable
assurances of its ability to effect any refund, when and if due.

         12.     PERSONS ENTITLED TO BENEFIT OF AGREEMENT.  This Agreement
shall inure to the benefit of the Company and the several Underwriters and,
with respect to the provisions of Section 9 hereof, the several parties (in
addition to the Company and the several Underwriters) indemnified under the
provisions of said Section 9, and their respective personal representatives,
