statement, as amended as of the date of this Agreement, meets the requirements
set forth in Rule 415(a)(1) under the Act and complies in all other material
Such registration statement, including the exhibits thereto, as amended as of

Company will comply with the requirements of Rule 434. The documents which are
incorporated by reference in any Final Prospectus or from which information is
so incorporated by reference, when they became effective or were filed with the
Commission, as the case may be, complied in all material respects with the
requirements of the Act and the rules and regulations thereunder or the Exchange
Act and the rules and regulations thereunder, as applicable, and did not, when

omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading, and any documents so filed and incorporated by
reference subsequent to the effective date of the Registration Statement shall,
when they are filed with the Commission, conform in all material respects with
the requirements of the Act and the rules and regulations thereunder and the
Exchange Act and the rules and regulations thereunder, as applicable. The

purchase will have, an authorized capitalization as set forth in the

     2. Purchase and Sale.

     (a) Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Company agrees to sell to
each Underwriter, and each Underwriter agrees, severally and not jointly, to
purchase from the Company the respective number of Initial Shares set forth
opposite such Underwriter's name in Schedule II hereto, except that, if Schedule
I hereto provides for the sale of Initial Shares pursuant to delayed delivery
arrangements, the respective amounts of Initial Shares to be purchased by the
Underwriters shall be set forth in Schedule II hereto, less the respective
amounts of Contract Securities determined as provided below. Shares to be
purchased by the Underwriters are herein sometimes called the "Underwriters'
Securities" and Shares to be purchased pursuant to Delayed Delivery Contracts as
hereinafter provided are herein called "Contract Securities."

     If so provided in Schedule I hereto, the Underwriters are authorized to
solicit offers to purchase Initial Shares from the Company pursuant to delayed
delivery contracts ("Delayed Delivery Contracts"), substantially in the form of
Schedule IV hereto but with such changes therein as the Company may authorize or
approve. The Underwriters will endeavor to make such arrangements and, as
compensation therefor, the Company will pay to the Representatives, for the
account of the Underwriters, on the Closing Date (as defined below), the
purchase price set forth on Schedule I hereto, of the Initial Shares for which
Delayed Delivery Contracts are made. Delayed Delivery Contracts are to be with
institutional investors, including commercial and savings banks, insurance

                                      -9-
<PAGE>

companies, pension funds, investment companies and educational and charitable
institutions. The Company will make Delayed Delivery Contracts in all cases
where sales of Contract Securities arranged by the Underwriters have been
approved by the Company but, except as the Company may otherwise agree, each
such Delayed Delivery Contract must be for not less than the minimum amount of
Initial Shares set forth in Schedule I hereto and the aggregate amount of
Contract Securities may not exceed the maximum aggregate amount set forth in
Schedule I hereto. The Underwriters will not have any responsibility in respect
of the validity or performance of Delayed Delivery Contracts. The amount of
Initial Shares to be purchased by each Underwriter as set forth in Schedule II
hereto shall be reduced by an amount which shall bear the same proportion to the
total amount of Contract Securities as the amount of Initial Shares set forth
opposite the name of such Underwriter bears to the aggregate amount set forth in
Schedule II hereto, except to the extent that you determine that such reduction
shall be otherwise than in such proportion and so advise the Company in writing;
provided, however, that the total amount of Initial Shares to be purchased by
all Underwriters shall be the aggregate amount set forth in Schedule II hereto,
less the aggregate amount of Contract Securities.

     (b) The initial public offering price and the purchase price of the Initial
Shares shall be set forth in a separate written instrument (the "Pricing
Agreement") signed by the Representatives and the Company, the form of which is
attached hereto as Schedule V. From and after the execution and delivery of the
Pricing Agreement, this Agreement shall be deemed to include the Pricing
Agreement. The purchase price per share to be paid by the several Underwriters
for the Initial Shares shall be an amount equal to the initial public offering
price, less an amount per share to be determined by agreement among the
Representatives and the Company.

     (c) In addition, on the basis of the representations and warranties
contained herein, and subject to the terms and conditions set forth herein, the
Company grants an option to the Underwriters, severally and not jointly, to
purchase up to an additional _______ Option Shares at the same price per share
determined as provided above for the Initial Shares. The option hereby granted
will expire 30 days after the date of the Pricing Agreement, and may be
exercised, in whole or in part (but not more than once by written notice) only
for the purpose of covering over-allotments upon notice by the Representatives
to the Company setting forth the number of Option Shares as to which the several
Underwriters are exercising the option, and the time and date of payment and
delivery thereof. Such time and date of delivery (the "Date of Delivery") shall
be determined by the Representatives but shall not be later than seven full
business days after the exercise of such option and not in any event prior to
the Closing Date (as defined below). If the option is exercised as to all or any
portion of the Option Shares, the Option Shares as to which the option is
exercised shall be purchased by the Underwriters severally and not jointly, in
proportion to, as nearly as practicable, their respective Initial Shares
underwriting obligations as set forth on Schedule II.

     3. Delivery and Payment. Delivery of and payment for the Initial Shares
shall be made on the date and at the time specified in the Pricing Agreement,
which date and time may be postponed by agreement between the Representatives
and the Company (such date and time of delivery and payment for the Initial
Shares being herein called the "Closing Date"). Delivery of the Initial Shares
shall be made to the Representatives for the respective accounts of the several
Underwriters against payment by the several Underwriters through the
Representatives of the purchase price thereof in the manner set forth in
Schedule I hereto. Unless otherwise agreed, certificates for the Initial Shares

                                      -10-
<PAGE>

shall be in the form set forth in Schedule I hereto, and such certificates may
be deposited with The Depository Trust Company ("DTC") or a custodian for DTC
and registered in the name of Cede & Co., as nominee for DTC.

     In addition, in the event that any or all of the Option Shares are
purchased by the Underwriters, delivery and payment for the Option Shares shall
be made at the office specified for delivery of the Initial Shares in the
Pricing Agreement, or at such other place as the Company and the Representatives
shall determine, on the Date of Delivery as specified in the notice from the
Representatives to the Company. Delivery of the Option Shares shall be made to
the Representatives against payment by the Underwriters through the
Representatives of the purchase price thereof to or upon the order of the
Company in the manner set forth in Schedule I hereto. Unless otherwise agreed,
certificates for the Option Shares shall be in the form set forth in Schedule I
hereto, and such certificates shall be registered in such names and in such
denominations as the Representatives may request not less than three full
business days in advance of the Date of Delivery.

     4. Agreements. The Company agrees with the several Underwriters that:

     (a) Prior to the termination of the offering of the Shares, the Company
will not file any amendment of the Registration Statement or supplement
(including any Final Prospectus) to the Basic Prospectus unless the Company has
furnished you a copy for your review prior to filing and will not file any such
proposed amendment or supplement to which you reasonably object. Subject to the
foregoing sentence, the Company will cause each Final Prospectus to be filed
with the Commission pursuant to Rule 424 or Rule 434 via EDGAR. The Company will
advise the Representatives promptly (i) when each Final Prospectus shall have
been filed with the Commission pursuant to Rule 424 or Rule 434, (ii) when any
amendment to the Registration Statement relating to the Shares shall have become
effective, (iii) of any request by the Commission for any amendment of the
Registration Statement or amendment of or supplement to the Final Prospectus or
for any additional information, (iv) of the issuance by the Commission of any
stop order suspending the effectiveness of the Registration Statement or the
institution or threatening of any proceeding for that purpose and (v) of the
receipt by the Company of any notification with respect to the suspension of the
qualification of the Shares for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose. The Company will use its
reasonable best efforts to prevent the issuance of any such stop order and, if
issued, to obtain as soon as possible the withdrawal thereof.

     (b) If, at any time when a prospectus relating to the Shares is required to
be delivered under the Act, except with respect to any such delivery requirement
imposed upon an affiliate of the Company in connection with any secondary market
sales, any event occurs as a result of which each Final Prospectus as then
amended or supplemented would include any 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, or if it
shall be necessary to amend or supplement the Final Prospectus to comply with
the Act or the Exchange Act or the respective rules thereunder, the Company
promptly will prepare and file with the Commission, subject to the first
sentence of paragraph (a) of this Section 4, an amendment or supplement which
will correct such statement or omission or an amendment which will effect such
compliance.

                                      -11-
<PAGE>

     (c) The Company will make generally available to its security holders and
to the Representatives as soon as practicable, but not later than 90 days after
the close of the period covered thereby, an earnings statement (in form
complying with the provisions of Rule 158 under the Act) covering a twelve month
period beginning not later than the first day of the Company's fiscal quarter
next following the "effective date" (as defined in said Rule 158) of the
Registration Statement.

     (d) The Company will furnish to the Representatives and counsel for the
Underwriters, without charge, copies of the Registration Statement (including
exhibits thereto) and each amendment thereto which shall become effective on or
prior to the Closing Date and, so long as delivery of a prospectus by an
Underwriter or dealer may be required by the Act, as many copies of any Final
Prospectus and any amendments thereof and supplements thereto as the
Representatives may reasonably request. The Company will pay the expenses of
printing all documents relating to the offering.

     (e) The Company will arrange for the qualification of the Shares for sale
under the laws of such jurisdictions as the Representatives may reasonably
designate, will maintain such qualifications in effect so long as required for
the distribution of the Shares; provided, however, that the Company shall not be
required to (i) qualify to do business in any jurisdiction where it is not now
so qualified, (ii) take any action which would subject it to general or
unlimited service of process of any jurisdiction where it is not now so subject,
(iii) become a dealer of securities or (iv) become subject to taxation in any
jurisdiction where it is not now so subject.

     (f) Until the business day following the Closing Date, the Company will
not, without the consent of the Representatives, offer or sell, or announce the
offering of, any securities covered by the Registration Statement or by any
other registration statement filed under the Act; provided, however, the Company
may, at any time, offer or sell or announce the offering of any securities (A)
covered by a registration statement on Form S-8 or (B) covered by a registration
statement on Form S-3 and pursuant to which the Company issues securities for
its dividend reinvestment plan.

     (g) The Company will prepare a prospectus supplement with respect to any
Shares sold by the Company pursuant to this Agreement, in a form previously
approved by the Underwriters, and to file such prospectus supplement pursuant to
Rule 424(b) under the Act not later than 5:00 p.m. on the second business day
after the signing of this Agreement, and to provide copies of such prospectus
supplement to the Underwriters via e-mail in ".pdf" format to an account
designated by the Underwriters.

     (h) The Company will make available to the Underwriters, as soon as
practicable after the Registration Statement becomes effective, and thereafter
from time to time to furnish to the Underwriters, as many copies of the Final
Prospectus (or of the Final Prospectus as amended or supplemented if the Company
shall have made any amendments or supplements thereto after the effective date
of the Registration Statement) as the Underwriters may reasonably request for
the purposes contemplated by the Act; and for so long as this Agreement is in
effect, or in any case if 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 and file

                                      -12-
<PAGE>

promptly such amendment or amendments to the Registration Statement and the
Final Prospectus as may be necessary to comply with the requirements of Section
10(a)(3) of the Act.

     (i) The Company will furnish to you for a period of one year from the date
of this Agreement (i) copies of any reports or other communications which the
Company shall send to its stockholders or shall from time to time publish or
publicly disseminate, (ii) copies of all annual, quarterly and current reports
filed with the Commission on Forms 10-K, 10-Q and 8-K, or such other similar
form as may be designated by the Commission, and (iii) copies of documents or
reports filed with any national securities exchange on which any class of
securities of the Company is listed, and to furnish to you from time to time
during the term of this Agreement such other information as you may reasonably
request regarding the Company or the Subsidiaries, in each case as soon as such
reports, communications, documents or information becomes available.

     (j) The Company will furnish to you four signed copies of the Registration
Statement, as initially filed with the Commission, and of all amendments
thereto, including all exhibits thereto and all documents incorporated by
reference therein.

     (k) The Company will furnish to you upon request as early as practicable
prior to the time of purchase a copy of the latest available unaudited interim
consolidated financial statements, if any, of the Company and its Subsidiaries
which have been read by the Company's independent certified public accountants,
as stated in their letter to be furnished pursuant to Section 6 hereof.

     (l) The Company will apply the net proceeds from the sale of the Shares in
the manner set forth under the caption "Use of Proceeds" in the Final
Prospectus.

     (m) The Company will pay all costs, expenses, fees and taxes in connection
with (i) the preparation and filing of the Registration Statement, each Basic
Prospectus, the Final Prospectus, and any amendments or supplements thereto, and
the printing and furnishing of copies of each thereof to the Underwriters and to
dealers (including costs of mailing and shipment), (ii) the registration, issue,
sale and delivery of the Shares, (iii) the producing, word processing and/or
printing of this Agreement, any powers of Attorney and any closing documents
(including compilations thereof) and the reproduction and/or printing and
furnishing of copies of each thereof to the Underwriters (including costs of
mailing and shipment), (iv) the qualification of the Shares for offering and
sale under state laws and the determination of their eligibility for investment
under state law as aforesaid (including the legal fees and filing fees and other
disbursements of counsel for the Underwriters) and the printing and furnishing
of copies of any blue sky surveys or legal investment surveys to the
Underwriters, (v) the listing of the Shares on the Nasdaq National Market System
(the "Exchange") and any registration thereof under the Exchange Act, (vi) any
filing for review of the public offering of the Shares by the NASD, including
the fees and disbursements of counsel to the Underwriters in connection
therewith, (vii) all other fees and disbursements of counsel to the Company, and
(viii) the performance of the Company's other obligations hereunder; provided
that the Underwriters shall be responsible for any transfer taxes on resale of
Shares by them.

                                      -13-
<PAGE>

     (n) The Company will furnish to you, before filing with the Commission
subsequent to the effective date of the Registration Statement and during the
period referred to in paragraph (i) above, a copy of any document proposed to be
filed pursuant to Section 13, 14 or 15(d) of the Exchange Act.

     5. Reimbursement of Underwriters' Expenses. If the Shares are not delivered
for any reason other than the termination of this Agreement pursuant to the
first two paragraphs of Section 8 hereof or the default by one or more of the
Underwriters in its or their respective obligations hereunder, the Company
shall, in addition to paying the amounts described in Section 4(m) hereof,
reimburse the Underwriters for all of their reasonable out-of-pocket expenses,
including the fees and disbursements of their counsel. If this agreement is
terminated pursuant to Section 9 hereof by reason of the default of one or more
Underwriters, the Company shall not be obligated to reimburse any defaulting
Underwriter on account of those expenses.

     6. Conditions to the Obligations of the Underwriters. The obligations of
the Underwriters to purchase the Shares shall be subject to the accuracy of the
representations and warranties on the part of the Company contained herein as of
the date hereof, as of the date of the effectiveness of any amendment to the
Registration Statement filed prior to the Closing Date (including the filing of
any document incorporated by reference therein) and as of the Closing Date, to
the accuracy of the statements of the Company made in any certificates pursuant
to the provisions hereof, to the performance by the Company of its obligations
hereunder and to the following additional conditions:

     (a) No stop order suspending the effectiveness of the Registration
Statement, as amended from time to time, shall have been issued and no
proceedings for that purpose shall have been instituted or threatened; and any
Final Prospectus shall have been filed or mailed for filing with the Commission
within the time period prescribed by the Commission.

     (b) The Company shall have furnished to the Representatives the opinion of
White & Case LLP, counsel for the Company, dated the Closing Date substantially
in the form attached hereto as Exhibit A.

     (c) The Company shall have furnished to the Representatives the opinion of
White & Case LLP, counsel for the Company, dated the Closing Date, as to certain
intellectual property matters.

     (d) The Representatives shall have received from counsel for the
Underwriters, such opinion or opinions, dated the Closing Date, with respect to
the issuance and sale of the Initial Shares, any Delayed Delivery Contracts, the
Registration Statement, the Final Prospectus and other related matters as the
Representatives may reasonably require, and the Company shall have furnished to
such counsel such documents as they request for the purpose of enabling them to
pass upon such matters.

     (e) The Company shall have furnished to the Representatives a certificate
of the Company, signed by the President and Chief Executive Officer or a Senior
Vice President and the principal financial or accounting officer of the Company,

                                      -14-
<PAGE>

dated the Closing Date, to the effect that the signers of such certificate have
carefully examined the Registration Statement, the Final Prospectus and this
Agreement and that to the best of their knowledge:

     (i) the representations and warranties of the Company in this Agreement are
true and correct in all material respects on and as of the Closing Date with the
same effect as if made on the Closing Date and the Company has complied with all
the agreements and satisfied all the conditions on its part to be performed or
satisfied at or prior to the Closing Date;

     (ii) no stop order suspending the effectiveness of the Registration
Statement, as amended, has been issued and no proceedings for that purpose have
been instituted or threatened; and

     (iii) since the date of the most recent financial statements included in
the Final Prospectus, there has been no material adverse change in the condition
(financial or other), earnings, business or properties of the Company and its
Subsidiaries, whether or not arising from transactions in the ordinary course of
business, except as set forth in or contemplated in the Final Prospectus.

     (f) At the Closing Date, Ernst & Young LLP shall have furnished to the
Representatives a letter or letters (which may refer to letters previously
delivered to one or more of the Representatives), dated as of the Closing Date,
in form and substance satisfactory to the Representatives.

     (g) Subsequent to the respective dates as of which information is given in
the Registration Statement and the Final Prospectus, there shall not have been
(i) any change or decrease specified in the letter or letters referred to in
paragraph (f) of this Section 6 or (ii) any change, or any development involving
a prospective change, in or affecting the earnings, business or properties of
the Company and its subsidiaries the effect of which, in any case referred to in
clause (i) or (ii) above, is, in the reasonable judgment of the Representatives,
so material and adverse as to make it impractical or inadvisable to proceed with
the offering or the delivery of the Shares as contemplated by the Registration
Statement and the Final Prospectus.

     (h) Prior to the Closing Date, the Company shall have furnished to the
Representatives such further information, certificates and documents as the
Representatives may reasonably request.

where sales of Contract Securities arranged by the Underwriters have been

     If any of the conditions specified in this Section 6 shall not have been

any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form

obligations of the Underwriters hereunder may be canceled at, or at any time
prior to, the Closing Date by the Representatives. Notice of such cancellation
shall be given to the Company in writing or by telephone or telegraph confirmed
in writing.

     7. Conditions to Purchase of Option Shares. In the event the Underwriters
exercise the option granted in Section 2(c) hereof to purchase all or any
portion of the Option Shares and the Date of Delivery determined by the
Representatives pursuant to Section 2 is later than the Closing Date, the
obligations of the several Underwriters to purchase and pay for the Option
Shares that they shall have respectively agreed to purchase hereunder are
subject to the accuracy of the representations and warranties of the Company
contained herein, to the performance by the Company of its obligations hereunder
and to the following additional conditions:

     (a) No stop order suspending the effectiveness of the Registration
Statement, as amended from time to time, shall have been issued and no
proceedings for that purpose shall have been instituted or threatened; and any
required filing of the Final Prospectus pursuant to Rule 424(b) or Rule 434
under the Act shall have been made within the proper time period.

     (b) At the Date of Delivery, the Representatives shall have received, each
dated the Date of Delivery and relating to the Option Shares:

     (i) the favorable opinion of White & Case LLP, counsel for the Company, in
form and substance satisfactory to counsel for the Underwriters, to the same
effect as the opinion required by Section 6(b);

     (ii) the favorable opinion of White & Case LLP, counsel for the Company, in

"specified date" in the letter furnished pursuant to this Section 7(b)(v) shall
be a date not more than five days prior to the Date of Delivery;

     (vi) Subsequent to the respective dates as of which information is given in
the Registration Statement and the Final Prospectus, there shall not have been
(i) any change or decrease specified in the letter or letters referred to in
paragraph (b)(v) of this Section 7 or (ii) any change, or any development
involving a prospective change, in or affecting the earnings, business or
properties of the Company and its subsidiaries the effect of which, in any case
referred to in clause (i) or (ii) above, is, in the judgment of the
Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or the delivery of the Shares as
contemplated by the Registration Statement and the Final Prospectus; and

     (vii) such other information, certificates and documents as the
Representatives may reasonably request.

                                      -16-
<PAGE>

     If any of the conditions specified in this Section 7 shall not have been
fulfilled in all material respects when and as provided in this Agreement, or if
any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Representatives and their counsel, this Agreement and all
obligations of the Underwriters hereunder may be canceled at, or at any time
prior to, the Date of Delivery by the Representatives. Notice of such
cancellation shall be given to the Company in writing or by telephone or
facsimile confirmed in writing.

     8. Effective Date of Agreement; Termination. This Agreement shall become
effective (i) if Rule 430A under the Act is not used, when you shall have
received notification of the effectiveness of the Registration Statement, or
(ii) if Rule 430A under the Act is used, when the parties hereto have executed
and delivered this Agreement.

     The obligations of the several Underwriters hereunder shall be subject to
termination in the absolute discretion of you or any group of Underwriters
(which may include you) which has agreed to purchase in the aggregate at least
50% of the Shares, if, since the time of execution of this Agreement or the
respective dates as of which information is given in the Registration Statement
and Final Prospectus, (y) there has been any material adverse and unfavorable
change, financial or otherwise (other than as referred to in the Registration
Statement and Final Prospectus at the time of execution of this Agreement), in
the operations, business, condition or prospects of the Company and its
Subsidiaries taken as a whole, which would, in your judgment or in the judgment
of such group of Underwriters, make it impracticable to market the Shares, or
(z) there shall have occurred any downgrading, or any notice shall have been
given of (i) any intended or potential downgrading or (ii) any review or
possible change that does not indicate an improvement, in the rating accorded
any securities of or guaranteed by the Company or any Subsidiary by any
"nationally recognized statistical rating organization", as that term is defined
in Rule 436(g)(2) under the Act or, if, at any time prior to the time of
purchase trading in securities on the New York Stock Exchange, the American
Stock Exchange or the Nasdaq National Market shall have been suspended or
limitations or minimum prices shall have been established on the New York Stock
Exchange, the American Stock Exchange or the Nasdaq National Market, or if a
banking moratorium shall have been declared either by the United States or New
York State authorities, or if the United States shall have declared war in
accordance with its constitutional processes or there shall have occurred any
material outbreak or escalation of hostilities or other national or
international calamity or crisis of such magnitude in its effect on the
financial markets of the United States as, in your judgment or in the judgment
of such group of Underwriters, to make it impracticable to market the Shares.

     If you or any group of Underwriters elects to terminate this Agreement as
provided in this Section 8, the Company and each other Underwriter shall be
notified promptly by letter or telegram.

     If the sale to the Underwriters of the Shares, as contemplated by this
Agreement, is not carried out by the Underwriters for any reason permitted under
this Agreement or if such sale is not carried out because the Company shall be
unable to comply with any of the terms of this Agreement, the Company shall not
be under any obligation or liability under this Agreement (except to the extent

                                      -17-
<PAGE>

provided in Sections 4(m), 5 and 9 hereof), and the Underwriters shall be under
no obligation or liability to the Company under this Agreement (except to the
extent provided in Section 9 hereof) or to one another hereunder.

     9. Increase in Underwriters' Commitments. Subject to Sections 6, 7 and 8,
if any Underwriter shall default in its obligation to take up and pay for the
Shares to be purchased by it hereunder (otherwise than for a reason sufficient
to justify the termination of this Agreement under the provisions of Section 8
hereof) and if the number of Shares which all Underwriters so defaulting shall
have agreed but failed to take up and pay for does not exceed 10% of the total
number of Shares, the non-defaulting Underwriters shall take up and pay for (in
addition to the aggregate number of Shares they are obligated to purchase
pursuant to Section 2 hereof) the number of Shares agreed to be purchased by all
such defaulting Underwriters, as hereinafter provided. Such Shares shall be
taken up and paid for by such non-defaulting Underwriter or Underwriters in such
amount or amounts as you may designate with the consent of each Underwriter so
designated or, in the event no such designation is made, such Shares shall be
taken up and paid for by all non-defaulting Underwriters pro rata in proportion
to the aggregate number of Shares set opposite the names of such non-defaulting
Underwriters in Schedule I.

     Without relieving any defaulting Underwriter from its obligations
hereunder, the Company agrees with the non-defaulting Underwriters that it will
not sell any Shares hereunder unless all of the Shares are purchased by the
Underwriters (or by substituted Underwriters selected by you with the approval
of the Company or selected by the Company with your approval).

     If a new Underwriter or Underwriters are substituted by the Underwriters or
by the Company for a defaulting Underwriter or Underwriters in accordance with
the foregoing provision, the Company or you shall have the right to postpone the
time of purchase for a period not exceeding five business days in order that any
necessary changes in the Registration Statement and Prospectus and other
documents may be effected.

     The term "Underwriter" as used in this Agreement shall refer to and include
any Underwriter substituted under this Section 9 with like effect as if such
substituted Underwriter had originally been named in Schedule I.

     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 five business
day period 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, and no action taken hereunder, shall relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

     10. Indemnity and Contribution.

                                      -18-
<PAGE>

     (a) The Company agrees to indemnify, defend and hold harmless each
Underwriter, its partners, directors and officers, and any person who controls
any Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, and the successors and assigns of all of the foregoing persons
from and against any loss, damage, expense, liability or claim (including the
reasonable cost of investigation) which, jointly or severally, any such
Underwriter or any such person may incur under the Act, the Exchange Act, the
common law or otherwise, insofar as such loss, damage, expense, liability or
claim arises out of or is based upon any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement (or in the
Registration Statement as amended by any post-effective amendment thereof by the
Company) or in a Prospectus (the term "Prospectus" for the purpose of this
Section 10 being deemed to include the Basic Prospectus and the Final Prospectus
as amended or supplemented by the Company), or arises out of or is based upon
any omission or alleged omission to state a material fact required to be stated
in either such Registration Statement or Prospectus or necessary to make the
statements made therein not misleading, except (i) insofar as any such loss,
damage, expense, liability or claim arises out of or is based upon any untrue
statement or alleged untrue statement of a material fact contained in and in
conformity with information furnished in writing by or on behalf of any
Underwriter through you to the Company expressly for use with reference to such
Underwriter in such Registration Statement or such Prospectus or arises out of
or is based upon any omission or alleged omission to state a material fact in
connection with such information required to be stated in such Registration
Statement or such Prospectus or necessary to make such information not
misleading, or (ii) with respect to any untrue statement or omission of material
fact made in the Prospectus, the indemnity agreement contained in this section
shall not inure to the benefit of any Underwriter from or through whom the
person asserting any such loss, claim, damage, liability or action purchased the
securities concerned, to the extent that any such loss, claim, damage, liability
or action of such Underwriter occurs under the circumstance where it shall have
been determined by a court of competent jurisdiction that (w) the Company had
previously furnished copies of the Prospectus, as amended or supplemented to the
Underwriter, (x) delivery of the Prospectus, as amended or supplemented, was
required by the Securities Act to be made to such person, (v) the untrue
statement or omission of a material fact contained in the Prospectus was
corrected in the Prospectus as amended or supplemented, and (z) there was not
sent or given to such person, at or prior to the written confirmation of the
sale of such securities to such person, a copy of the Prospectus as amended or
supplemented.

     If any action, suit or proceeding (together, a "Proceeding") is brought
against an Underwriter or any such person in respect of which indemnity may be
sought against the Company pursuant to the foregoing paragraph, such Underwriter
or such person shall promptly notify the Company in writing of the institution
of such Proceeding and the Company shall assume the defense of such Proceeding,
including the employment of counsel reasonably satisfactory to such indemnified
party and payment of all reasonable fees and expenses; provided, however, that
the omission to so notify the Company shall not relieve the Company from any
liability which the Company may have to any Underwriter or any such person or
otherwise. Such Underwriter or such person shall have the right to employ its or
their own counsel in any such case, but the fees and expenses of such counsel
shall be at the expense of such Underwriter or of such person unless the
employment of such counsel shall have been authorized in writing by the Company

                                      -19-
<PAGE>

in connection with the defense of such Proceeding or the Company shall not have,
within a reasonable period of time in light of the circumstances, employed
counsel to have charge of the defense of such Proceeding or such indemnified
party or parties shall have reasonably concluded based on advice of counsel that
there may be defenses available to it or them which are different from,
additional to or in conflict with those available to the Company (in which case
the Company shall not have the right to direct the defense of such Proceeding on
behalf of the indemnified party or parties), in any of which events such
reasonable fees and expenses shall be borne by the Company and paid as incurred
(it being understood, however, that the Company shall not be liable for the
reasonable expenses of more than one separate counsel (in addition to any local
counsel) in any one Proceeding or series of related Proceedings in the same
jurisdiction representing the indemnified parties who are parties to such
Proceeding). The Company shall not be liable for any settlement of any
Proceeding effected without its written consent but if settled with the written
consent of the Company, the Company agrees to indemnify and hold harmless any
Underwriter and any such person from and against any loss or liability by reason
of such settlement. Notwithstanding the foregoing sentence, if at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by the second
sentence of this paragraph, then the indemnifying party agrees that it shall be
liable for any settlement of any Proceeding effected without its written consent
if (i) such settlement is entered into more than 60 business days after receipt
by such indemnifying party of the aforesaid request, (ii) such indemnifying
party shall not have reimbursed the indemnified party in accordance with such
request prior to the date of such settlement and (iii) such indemnified party
shall have given the indemnifying party at least 30 days' prior notice of its
intention to settle. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened Proceeding in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party, unless such settlement includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such Proceeding and does not include an admission of fault, culpability or a
failure to act, by or on behalf of such indemnified party.

     (b) Each Underwriter severally agrees to indemnify, defend and hold
harmless the Company, its directors and officers, and any person who controls
the Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, and the successors and assigns of all of the foregoing persons
from and against any loss, damage, expense, liability or claim (including the
reasonable cost of investigation) which, jointly or severally, the Company or
any such person may incur under the Act, the Exchange Act, the common law or
otherwise, insofar as such loss, damage, expense, liability or claim arises out
of or is based upon any untrue statement or alleged untrue statement of a
material fact contained in and in conformity with information furnished in
writing by or on behalf of such Underwriter through you to the Company expressly
for use with reference to such Underwriter in the Registration Statement (or in
the Registration Statement as amended by any post-effective amendment thereof by
the Company) or in a Prospectus, or arises out of or is based upon any omission
or alleged omission to state a material fact in connection with such information
required to be stated in such Registration Statement or such Prospectus or
necessary to make such information not misleading.

     If any Proceeding is brought against the Company or any such person in
respect of which indemnity may be sought against any Underwriter pursuant to the
foregoing paragraph, the Company or such person shall promptly notify such

                                      -20-
<PAGE>

Underwriter in writing of the institution of such Proceeding and such
Underwriter shall assume the defense of such Proceeding, including the
employment of counsel reasonably satisfactory to such indemnified party and
payment of all fees and expenses; provided, however, that the omission to so
notify such Underwriter shall not relieve such Underwriter from any liability
which such Underwriter may have to the Company or any such person or otherwise.
The Company or such person shall have the right to employ its own counsel in any
such case, but the fees and expenses of such counsel shall be at the expense of
the Company or such person unless the employment of such counsel shall have been
authorized in writing by such Underwriter in connection with the defense of such
Proceeding or such Underwriter shall not have, within a reasonable period of
time in light of the circumstances, employed counsel to have charge of the
defense of such Proceeding or such indemnified party or parties shall have
reasonably concluded that there may be defenses available to it or them which
are different from or additional to or in conflict with those available to such
Underwriter (in which case such Underwriter shall not have the right to direct
the defense of such Proceeding on behalf of the indemnified party or parties,
but such Underwriter may employ counsel and participate in the defense thereof
but the fees and expenses of such counsel shall be at the expense of such
Underwriter), in any of which events such reasonable fees and expenses shall be
borne by such Underwriter and paid as incurred (it being understood, however,
that such Underwriter shall not be liable for the reasonable expenses of more
than one separate counsel (in addition to any local counsel) in any one
Proceeding or series of related Proceedings in the same jurisdiction
representing the indemnified parties who are parties to such Proceeding). No
Underwriter shall be liable for any settlement of any such Proceeding effected
without the written consent of such Underwriter but if settled with the written
consent of such Underwriter, such Underwriter agrees to indemnify and hold
harmless the Company and any such person from and against any loss or liability
by reason of such settlement. Notwithstanding the foregoing sentence, if at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
by the second sentence of this paragraph, then the indemnifying party agrees
that it shall be liable for any settlement of any Proceeding effected without
its written consent if (i) such settlement is entered into more than 60 business
days after receipt by such indemnifying party of the aforesaid request, (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement and (iii) such
indemnified party shall have given the indemnifying party at least 30 days'
prior notice of its intention to settle. No indemnifying party shall, without
the prior written consent of the indemnified party, effect any settlement of any
pending or threatened Proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such Proceeding.

     (c) If the indemnification provided for in this Section 10 is unavailable
to an indemnified party under subsections (a) and (b) of this Section 10 in
respect of any losses, damages, expenses, liabilities or claims referred to
therein, then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, damages, expenses, liabilities or
claims (i) in such proportion as is appropriate to reflect the relative benefits
received by the Company on the one hand and the Underwriters on the other hand
from the offering of the Shares or (ii) if the allocation provided by clause (i)

                                      -21-
<PAGE>

above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company on the one hand and of the Underwriters
on the other in connection with the statements or omissions which resulted in
such losses, damages, expenses, liabilities or claims, 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 proceeds from the offering (net of
underwriting discounts and commissions but before deducting expenses) received
by the Company and the total underwriting discounts and commissions received by
the Underwriters, bear to the aggregate public offering price of the Shares. The
relative fault of the Company on the one hand and of the Underwriters on the
other shall be determined by reference to, among other things, whether the
untrue statement or alleged untrue statement of a material fact or omission or
alleged omission relates to information supplied by the Company or by the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The amount
paid or payable by a party as a result of the losses, damages, expenses,
liabilities and claims referred to in this subsection shall be deemed to include
any legal or other fees or expenses reasonably incurred by such party in
connection with investigating, preparing to defend or defending any Proceeding.

     (d) The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 10 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 in subsection (c) above. Notwithstanding
the provisions of this Section 10, 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 such Underwriter and distributed to the public were
offered to the public exceeds the amount of any damage which such Underwriter
has otherwise been required to pay by reason of such untrue statement or alleged
untrue statement or omission or alleged omission. 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 to contribute pursuant to this
Section 10 are several in proportion to their respective underwriting
commitments and not joint.

     (e) The indemnity and contribution agreements contained in this Section 10
and the covenants, warranties and representations of the Company contained in
this Agreement shall remain in full force and effect regardless of any
investigation made by or on behalf of any Underwriter, its partners, directors
or officers or any person (including each partner, officer or director of such
person) who controls any Underwriter within the meaning of Section 15 of the Act
or Section 20 of the Exchange Act, or by or on behalf of the Company, its
directors or officers or any person who controls the Company within the meaning
of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive
any termination of this Agreement or the issuance and delivery of the Shares.
The Company and each Underwriter agree promptly to notify each other of the
commencement of any Proceeding against it and, in the case of the Company,
against any of the Company's officers or directors in connection with the
issuance and sale of the Shares, or in connection with the Registration
Statement or Prospectus.

     11. Representations and Indemnities to Survive. The respective agreements,
representations, warranties, indemnities and other statements of the Company or
its officers and of the Underwriters set forth in or made pursuant to this

                                      -22-
<PAGE>

Agreement will remain in full force and effect, regardless of any investigation
made by or on behalf of any Underwriter or the Company or any of the officers,
directors or controlling persons referred to in Section 10 hereof, and will
survive delivery of and payment for the Shares. The provisions of Section 8 and
10 hereof and this Section 11 shall survive the termination or cancellation of
this Agreement.

     12. Notices. All communications hereunder will be in writing and effective
only on receipt, and, if sent to the Representatives, will be mailed, delivered
by courier or facsimile and confirmed to them, at the address specified in
Schedule I hereto, with a copy to: [ ]; or, if sent to the Company, will be
mailed, delivered by courier or facsimile and confirmed to it at Aphton
Corporation, 80 S.W. 8th Street, Miami, Florida 331, Attention: Phil Gevas.

     13. Successors. This Agreement will inure to the benefit of and be binding
upon the parties hereto and their respective successors and the officers and
directors and controlling persons referred to in Section 8 hereof, and no other
person will have any right or obligation hereunder.

     14. Counterparts. This Agreement may be executed in any number of
counterparts, all of which shall constitute a single instrument.

     15. Applicable Law. This Agreement will be governed by and construed in
accordance with the internal laws of the State of New York, without giving
effect to principles of conflict of laws.

Dear Sirs:

     The undersigned hereby agrees to purchase from Aphton Corporation, a

     Payment for the Shares to be purchased by the undersigned shall be made on
or before 11:00 A.M. on the Delivery Date to or upon the order of the Company in
New York Clearing House (next day) funds, at your office or at such other place
as shall be agreed between the Company and the undersigned upon delivery to the
undersigned of the Shares in definitive fully registered form and in such
authorized denominations and registered in such names as the undersigned may
request by written or telegraphic communication addressed to the Company not
less than five full business days prior to the Delivery Date. If no request is
received, the Shares will be registered in the name of the undersigned and
issued in a denomination equal to the aggregate amount of Shares to be purchased
by the undersigned on the Delivery Date.

     The obligation of the undersigned to take delivery of and make payment for
Shares on the Delivery Date, and the obligation of the Company to sell and
deliver Shares on the Delivery Date, shall be subject to the conditions (and
neither party shall incur any liability by reason of the failure thereof) that
(1) the purchase of Shares to be made by the undersigned, which purchase the
undersigned represents is not prohibited on the date hereof, shall not on the
Delivery Date be prohibited under the laws of the jurisdiction to which the

opinion of counsel for the Company delivered to the Underwriters in connection

payment for the Shares, and the obligation of the Company to cause the Shares to
be sold and delivered, shall not be affected by the failure of any purchaser to
take delivery of and make payment for the Shares pursuant to other contracts
similar to this contract.

                                      -28-

hereto and their respective successors, but will not be assignable by either

[Date]

[To the Representatives
Named in Schedule I of the Agreement]

Re:      Aphton Corporation

Ladies and Gentlemen:

     We have acted as special counsel for Aphton Corporation, a Delaware
corporation ("the Company"), in connection with (i) the execution and delivery
of an Underwriting Agreement, dated [___________] (the "Underwriting
Agreement"), among the Company, and [_______________________________], (the
"Underwriters"), providing for the purchase by the Underwriters from the
Company, upon the terms and conditions set forth in the Underwriting Agreement,
of an aggregate of [_____________] shares of the Company's common stock, par
value $.001 per share (the "Shares"), and (ii) the preparation and filing by the
Company with the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Act") of the Registration Statement on
Form S-3 (File No. ______________). As described in the Prospectus, the
Company's Annual Report on Form 10-K/A for the year ended __________, its
Quarterly Report(s) on Form 10-Q for the months ended _______________, its
Current Report(s) on Form 8-K dated ______________________________, and the
description of the Company's common stock contained in the Company's
Registration Statement on Form 8-A, filed with the Commission on January 30,
1998 (collectively, the "Incorporated Documents"), are incorporated in the
Prospectus by reference.

     In so acting, we have examined such certificates of public officials, and
certificates of officers of the Company, and the originals (or copies thereof
certified to our satisfaction) of such corporate documents and records of the
Company, and such other documents, records and papers as we have deemed relevant
in order to give the opinions hereinafter set forth. In this connection, we have
assumed the genuineness of signatures on, the authenticity of all documents
submitted to us as originals and the conformity to authentic original documents
of all documents submitted to us as certified, conformed or photostatic copies.
Also, we have relied upon such certificates of public officials, and officers of
the Company and such other certifications with respect to the accuracy of
material factual matters contained therein which were not independently
established. We did not participate in the preparation of the Incorporated
Documents or review any of them prior to their being filed with the Commission
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), but
we did review them in connection with our participation in the preparation of
the Prospectus.

                                      -33-
<PAGE>

     Based upon and subject to the foregoing, it is our opinion that:

          1. The Company has been duly incorporated and is validly existing as a
     corporation in corporate good standing under the laws of the State of
     Delaware and has the corporate power and authority to own, lease and
     operate its properties and conduct its business as described in the
     Registration Statement, to enter into the Underwriting Agreement, to issue,
     sell and deliver the Shares and to consummate the transactions contemplated
     in the Prospectus.

          2. The Common Stock of the Company, including the Shares, conforms in
     all material respects to the description thereof contained in the
     Registration Statement and the Prospectus.

          3. The Shares have been duly and validly authorized by the Company for
     offer, sale, issuance and delivery pursuant to the Underwriting Agreement
     and, when issued and delivered against payment therefor as provided in the
     Underwriting Agreement, will be duly and validly issued and fully paid and
     non-assessable.

          4. To our knowledge and other than as set forth in the Prospectus,
     there is no legal or governmental proceeding threatened in writing or
     pending in any state or federal court to which the Company is a party or to
     which any property of the Company is subject, which could prevent
     consummation of the transactions contemplated by the Underwriting
     Agreement.

          5. The Underwriting Agreement has been duly authorized, executed and
     delivered by the Company.

          6. The execution, delivery and performance of the Underwriting
     Agreement, the issuance and sale of the Shares and the consummation of the
     transactions contemplated by the Underwriting Agreement will not conflict
     with, or result in any breach of or constitute a default under (nor
     constitute any event which with notice, lapse of time, or both would result
     in any breach of, or constitute a default under), (i) any provisions of the
     charter or by-laws of the Company or, (ii) under any provision of any
     license, indenture, mortgage, deed of trust, bank loan or credit agreement
     or other evidence of indebtedness, or any lease, contract or other
     agreement or instrument to which the Company is a party or by which it or
     its property may be bound or affected and which have been filed by the
     Company with the Commission under the Exchange Act, and are listed in the
     exhibit index to the Company's most recent Annual Report on Form 10-K/A or
     were subsequently filed prior to the date hereof under the Exchange Act, or
     (iii) under any decree, judgment or order known to us to be applicable to
     the Company or under any U.S. Federal or New York State law, regulation or
     rule which in our experience are normally applicable to transactions of the
     type contemplated by the Underwriting Agreement, except in the case of
     clauses (ii) and (iii) for such conflicts, breaches, or defaults,
     individually or in the aggregate, as would not reasonably be expected to
     have a material adverse effect on the business, properties, prospects,
     financial condition or results of operation of the Company taken as a
     whole.

          7. No approval, authorization, consent or order of or filing with any
     New York State or U.S. Federal governmental agency or body or any New York
     State or U.S. Federal court is required to be obtained or made by the
     Company for the issuance and sale of the Shares or the consummation by the
     Company of the transactions as contemplated by the Underwriting Agreement
     except such as may be required by the Act and the applicable rules and
     regulations thereunder, the securities or blue sky laws of the various
     jurisdictions in which the Shares are being offered by the Underwriters (as
     to which we express no opinion) or under the rules and regulations of the
     National Association of Securities Dealers, Inc. (as to which we express no
     opinion).

          8. The Company is not and, after giving effect to the offering and
     sale of the Shares, will not be required to register as an "investment
     company" as such term is defined in the Investment Company Act of 1940, as
     amended.

     In passing upon the form of the Registration Statement and the Prospectus,
we necessarily have assumed the accuracy and completeness of the information
included or incorporated by reference therein by the Company and the
responsiveness to the applicable forms, rules and regulations of the Commission
promulgated under the Exchange Act of the information included in the
Incorporated Documents by the Company and we take no responsibility therefor.
Based upon such assumptions, in our opinion the Registration Statement, as of
its effective date, and the Prospectus, as of its date (except in each case for
the financial statements and schedules and other financial and statistical data
contained or incorporated by reference therein or omitted therefrom, as to which
we express no opinion), appeared on their face to comply as to form in all
material respects with the requirements of the Act and the rules and regulations
of the Commission thereunder.

     In the course of the preparation by the Company of the Registration
Statement and the Prospectus (other than the Incorporated Documents), we have
participated in conferences with certain officers of the Company, with
representatives of the independent auditors of the Company, and with you and
your counsel. Based upon such participation in the preparation of the
Registration Statement and the Prospectus (other than the Incorporated
Documents), and our review and discussion of the contents thereof, but without
independent check or verification except as otherwise specified above, nothing
has come to our attention which causes us to believe that the Registration
Statement, as of its effective date, or the Prospectus, as of its date, (except
in each case for the financial statements and schedules and other financial or
statistical data contained or incorporated by reference therein or omitted
therefrom as to which we express no belief), contained any untrue statement of a
material fact or omitted therefrom to state any material fact required to be
stated therein or necessary to make the statements therein (in the case of the
Prospectus, in the light of the circumstances under which they were made) not
misleading.

     The opinions expressed above are limited to questions arising under the
Federal Law of the United States, the General Corporation Law of the State of
Delaware and the law of the State of New York. This opinion may not be relied
upon by or published or communicated to any person and may not be used for any
other purpose whatsoever without prior written approval in each instance.

                                   Very truly yours,

                                      -35-
