Dear Sirs:

                  Section 1. INTRODUCTORY.  Inter-Tel,  Incorporated, an Arizona
corporation (the "Company"),  proposes to issue and sell 2,000,000 shares of its
authorized  but  unissued   Common  Stock  (the  "Common   Stock")  and  certain
shareholders  of the Company  named in Schedule B annexed  hereto (the  "Selling
Shareholders")  propose to sell an aggregate of 850,000  shares of the Company's
issued  and  outstanding  Common  Stock  to you  (sometimes  called  herein  the
"Underwriters").  Said aggregate of 2,850,000 shares are herein called the "Firm
Common Shares." In addition,  one of the Selling Shareholders  proposes to grant
to the  Underwriters  an option to purchase up to 427,500  additional  shares of
Common Stock (the "Optional  Common  Shares"),  as provided in Section 5 hereof.
The Firm Common Shares and, to the extent such option is exercised, the Optional
Common Shares are hereinafter collectively referred to as the "Common Shares."

                  You have advised the Company and the Selling Shareholders that
you propose to make a public offering of your respective  portions of the Common
Shares on the effective date of the registration  statement hereinafter referred
to, or as soon thereafter as in your judgment is advisable.

                  The  Company  and  each  of the  Selling  Shareholders  hereby
confirm their  respective  agreements with respect to the purchase of the Common
Shares by the Underwriters as follows:

                  Section 2.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The
Company hereby represents and warrants to the several Underwriters that:

                  (a) A registration  statement on Form S-3 (File No.  33-_____)
with respect to the Common Shares has been prepared by the Company in conformity
with the requirements of the Securities Act of 1933, as amended (the "Act"), and
the rules and regulations  (the "Rules and  Regulations")  of the Securities and
Exchange Commission (the "Commission") thereunder, and has

                                       -1-




been  filed with the  Commission.  The  Company  has  prepared  and has filed or
proposes to file prior to the effective date of such  registration  statement an
amendment or  amendments  to such  registration  statement,  which  amendment or
amendments have been or will be similarly prepared. There have been delivered to
you two signed copies of such  registration  statement and  amendment,  together
with two  copies  of each  exhibit  filed  therewith.  Conformed  copies of such
registration  statement and amendments (but without exhibits) and of the related
preliminary  prospectus have been delivered to you in such reasonable quantities
as you have requested. The Company will next file with the Commission one of the
following:  (i) prior to effectiveness of such registration statement, a further
amendment  thereto,  including  the  form of final  prospectus,  or (ii) a final
prospectus  in  accordance   with  Rules  430A  and  424(b)  of  the  Rules  and
Regulations.  As filed,  such  amendment and form of final  prospectus,  or such
final  prospectus,  shall  include  all Rule 430A  Information  (as  hereinafter
defined)  and,  except  to the  extent  that you  shall  agree in  writing  to a
modification,  shall be in all substantive respects in the form furnished to you
prior to the date and time that this Agreement was executed and delivered by the
parties  hereto,  or, to the extent not  completed at such date and time,  shall
contain only such specific additional information and other changes (beyond that
contained  in the  latest  Preliminary  Prospectus)  as the  Company  shall have
previously advised you in writing would be included or made therein.

         The term "Registration  Statement" as used in this Agreement shall mean
such  registration  statement at the time such  registration  statement  becomes
effective  and,  in the  event  any  post-effective  amendment  thereto  becomes
effective prior to the First Closing Date (as hereinafter  defined),  shall also
mean such registration  statement as so amended;  provided,  however,  that such
term shall also include (i) all Rule 430A  Information  deemed to be included in
such  registration  statement at the time such  registration  statement  becomes
effective  as  provided  by Rule 430A of the Rules  and  Regulations  and (ii) a
registration  statement,  if any, filed pursuant to Rule 462(b) of the Rules and
Regulations  relating to the Common Shares.  The term  "Preliminary  Prospectus"
shall mean any preliminary prospectus referred to in the preceding paragraph and
any preliminary prospectus included in the Registration Statement at the time it
becomes  effective that omits Rule 430A  Information.  The term  "Prospectus" as
used in this Agreement  shall mean the prospectus  relating to the Common Shares
in the form in which it is first  filed  with the  Commission  pursuant  to Rule
424(b) of the Rules and  Regulations or, if no filing pursuant to Rule 424(b) of
the Rules and Regulations is required,  shall mean the form of final  prospectus
included in the Registration  Statement at the time such registration  statement
becomes  effective.  The term "Rule 430A  Information"  means  information  with
respect to the Common  Shares and the offering  thereof  permitted to be omitted
from the Registration  Statement when it becomes effective pursuant to Rule 430A
of the Rules and Regulations. Any reference herein to any Preliminary Prospectus
or the  Prospectus  shall  be  deemed  to  refer to and  include  the  documents
incorporated by reference  therein pursuant to Form S-3 under the Act, as of the
date of such Preliminary Prospectus or Prospectus, as the case may be.

                  (b) The  Commission  has not  issued any order  preventing  or
suspending  the  use  of  any  Preliminary  Prospectus,   and  each  Preliminary
Prospectus has conformed in all material respects to the requirements of the Act
and the Rules and  Regulations  and, as of its date, has not included any untrue
statement of a material  fact or omitted to state a material  fact  necessary to
make the statements  therein, in the light of the circumstances under which they
were made, not misleading;  and at the time the Registration  Statement  becomes
effective,  and at all times subsequent thereto up to and including each Closing
Date hereinafter mentioned,  the Registration Statement and the Prospectus,  and
any amendments or supplements thereto,  will contain all material statements and
information  required  to be  included  therein  by the Act and  the  Rules  and
Regulations and will in all material respects conform to the requirements of the
Act and the Rules and Regulations, and neither the Registration Statement

                                       -2-



nor the Prospectus,  nor any amendment or supplement  thereto,  will include any
untrue statement of a material fact or omit to state a material fact required to
be stated  therein or necessary to make the statements  therein not  misleading;
provided,  however,  no representation or warranty  contained in this subsection
2(b)  shall be  applicable  to  information  contained  in or  omitted  from any
Preliminary Prospectus,  the Registration Statement,  the Prospectus or any such
amendment  or  supplement  in  reliance  upon  and in  conformity  with  written
information furnished to the Company by or on behalf of you specifically for use
in the  preparation  thereof.  The  documents  incorporated  by reference in the
Prospectus, when they were filed with the Commission,  conformed in all material
respects to the requirements of the Securities  Exchange Act of 1934, as amended
(the "Exchange Act") and the rules and regulations of the Commission thereunder,
and none of such documents  contained an untrue  statement of a material fact or
omitted to state a material fact  required to be stated  therein or necessary to
make the statements therein not misleading.

                  (c)  The  Company  does  not  own  or  control,   directly  or
indirectly,  any  corporation,  association  or  other  entity  other  than  the
subsidiaries  listed in Exhibit  22.1 to the Annual  Report on Form 10-K for the
Company's  most recent fiscal year (the  "Company  Form 10-K").  The Company and
each of its subsidiaries have been duly incorporated and are validly existing as
corporations in good standing under the laws of their  respective  jurisdictions
of incorporation, with full power and authority (corporate and other) to own and
lease their properties and conduct their  respective  businesses as described in
the  Prospectus;   the  Company,  or  one  of  its  wholly-owned   subsidiaries,
beneficially owns all of the outstanding  capital stock of its subsidiaries free
and clear of all claims,  liens, charges and encumbrances;  the Company and each
of its  subsidiaries  are in possession of and operating in compliance  with all
authorizations, licenses, permits, consents, certificates and orders material to
the conduct of their respective  businesses,  all of which are valid and in full
force and effect; the Company and each of its subsidiaries are duly qualified to
do business and in good standing as foreign corporations in each jurisdiction in
which the ownership or leasing of properties or the conduct of their  respective
businesses  requires such  qualification,  except for jurisdictions in which the
failure to so qualify would not have a material  adverse effect upon the Company
or the subsidiary;

                  (d) As of June  30,  1995,  the  Company  had  authorized  and
outstanding capital stock as set forth under the heading "Capitalization" in the
Prospectus; the issued and outstanding shares of the Company's Common Stock have
been duly authorized and validly issued, are fully paid and  nonassessable,  are
duly listed on The Nasdaq Stock Market,  have been issued in compliance with all
federal and state securities laws, were not issued in violation of or subject to
any preemptive  rights or other rights to subscribe for or purchase  securities,
and conform to the description  thereof contained in the Prospectus.  All issued
and  outstanding  shares of capital stock of each subsidiary of the Company have
been duly  authorized and validly  issued and are fully paid and  nonassessable.
Except as disclosed  in or  contemplated  by the  Prospectus  and the  financial
statements  of the  Company,  and the  related  notes  thereto,  included in the
Prospectus,  neither the Company nor any subsidiary has  outstanding any options
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, stock bonus and other stock plans or arrangements, and the options
or other rights granted and exercised  thereunder,  set forth in or incorporated
by reference in the Prospectus  accurately and fairly  presents the  information
required  to be shown with  respect to such  plans,  arrangements,  options  and
rights.

                  (e) The Common Shares to be sold by the Company have been duly
authorized  and, when issued,  delivered and paid for in the manner set forth in
this Agreement, will be duly

                                       -3-



authorized,  validly issued,  fully paid and nonassessable,  and will conform to
the description  thereof  contained in the Prospectus.  No preemptive  rights or
other rights to subscribe for or purchase exist with respect to the issuance and
sale  of the  Common  Shares  by the  Company  pursuant  to this  Agreement.  No
shareholder  of the Company has any right which has not been waived or satisfied
to  require  the  Company  to  register  the  sale of any  shares  owned by such
shareholder under the Act in the public offering contemplated by this Agreement.
No further  approval or authority of the  shareholders or the Board of Directors
of the Company will be required  for the transfer and sale of the Common  Shares
to be sold by the Selling  Shareholders  or the  issuance and sale of the Common
Shares to be sold by the Company as contemplated herein.

                  (f) The Company has full legal right,  power and  authority to
enter into this Agreement and perform the transactions contemplated hereby. This
Agreement  has been duly  authorized,  executed and delivered by the Company and
constitutes a valid and binding obligation of the Company in accordance with its
terms.  The making and  performance  of this  Agreement  by the  Company and the
consummation  of the  transactions  herein  contemplated  will not  violate  any
provisions of the articles of incorporation or bylaws,  or other  organizational
documents,  of the  Company or any of its  subsidiaries,  and will not  conflict
with,  result in the breach or violation of, or constitute,  either by itself or
upon  notice or the  passage  of time or both,  a default  under any  agreement,
mortgage, deed of trust, lease, franchise,  license,  indenture, permit or other
instrument  to which the  Company  or any of its  subsidiaries  is a party or by
which the Company or any of its subsidiaries or any of its respective properties
may be  bound  or  affected,  and  which  is  material  to the  Company  and its
subsidiaries,  as a whole, any statute or any authorization,  judgment,  decree,
order,  rule or regulation of any court or any regulatory  body,  administrative
agency  or other  governmental  body  applicable  to the  Company  or any of its
subsidiaries  or any of  their  respective  properties.  No  consent,  approval,
authorization  or other  order of any  court,  regulatory  body,  administrative
agency or other  governmental body is required for the execution and delivery of
this Agreement or the  consummation  of the  transactions  contemplated  by this
Agreement,  except for compliance  with the Act, the Blue Sky laws applicable to
the public  offering of the Common  Shares by the several  Underwriters  and the
clearance of such offering with the National  Association of Securities Dealers,
Inc. (the "NASD").

                  (g) Ernst & Young LLP, who have  expressed  their opinion with
respect to the financial statements and schedules included in or incorporated by
reference in the Prospectus and in the Registration  Statement,  are independent
accountants as required by the Act and the Rules and Regulations.

                  (h) The financial statements and schedules of the Company, and
the related  notes  thereto,  included in or  incorporated  by  reference in the
Registration  Statement and the Prospectus present fairly the financial position
of the  Company as of the  respective  dates of such  financial  statements  and
schedules,  and the results of operations  and changes in financial  position of
the  Company  for the  respective  periods  covered  thereby.  Such  statements,
schedules  and related notes have been  prepared in  accordance  with  generally
accepted accounting principles applied on a consistent basis as certified by the
independent  accountants named in subsection 2(g). No other financial statements
or schedules  are  required to be included in the  Registration  Statement.  The
selected  financial and statistical  data set forth in the Prospectus  under the
captions  "Capitalization"  and "Selected  Consolidated  Financial  Data" fairly
present  the   information  set  forth  therein  on  the  basis  stated  in  the
Registration Statement.

                  (i) Except as  disclosed in the  Prospectus,  and except as to
defaults  which  individually  or in the aggregate  would not be material to the
Company and its subsidiaries, as a whole,

                                       -4-



neither the Company nor any of its  subsidiaries  is in  violation or default of
any   provision  of  its  articles  of   incorporation   or  bylaws,   or  other
organizational  documents,  or is in breach of or  default  with  respect to any
provision of any agreement,  judgment,  decree, order, mortgage,  deed of trust,
lease, franchise,  license, indenture, permit or other instrument to which it is
a party or by which it or any of its  properties  are bound;  and there does not
exist any state of facts  which  constitutes  an event of default on the part of
the Company or any such  subsidiary as defined in such documents or which,  with
notice or lapse of time or both, would constitute such an event of default.

                  (j) There are no contracts or other  documents  required to be
described  in the  Registration  Statement  or to be  filed as  exhibits  to the
Registration Statement by the Act or by the Rules and Regulations which have not
been  described  or  filed  as  required.  The  contracts  so  described  in the
Prospectus  are in full force and effect on the date  hereof;  and  neither  the
Company nor any of its subsidiaries, nor to the best of the Company's knowledge,
any other party is in breach of or default under any of such contracts.

                  (k) Except as disclosed in the Prospectus,  there are no legal
or  governmental  actions,  suits or proceedings  pending or, to the best of the
Company's knowledge,  threatened to which the Company or any of its subsidiaries
is or may be a party or of which  property owned or leased by the Company or any
of its  subsidiaries is or may be the subject,  or related to  environmental  or
discrimination  matters, which actions, suits or proceedings would reasonably be
expected to,  individually or in the aggregate,  prevent or adversely affect the
transactions  contemplated  by this  Agreement  or result in a material  adverse
change in the condition (financial or otherwise),  properties, business, results
of operations or prospects of the Company and its subsidiaries,  as a whole; and
no labor  disturbance by the employees of the Company or any of its subsidiaries
exists or is imminent  which would  reasonably  be expected to affect  adversely
such  condition,  properties,  business,  results of  operations  or  prospects.
Neither  the Company  nor any of its  subsidiaries  is a party or subject to the
provisions of any material injunction,  judgment,  decree or order of any court,
regulatory body, administrative agency or other governmental body.

                  (l) The  Company  or the  applicable  subsidiary  has good and
marketable  title to all the  properties  and assets  reflected  as owned in the
financial  statements  hereinabove  described (or elsewhere in the  Prospectus),
subject to no lien, mortgage,  pledge,  charge or encumbrance of any kind except
(i) those, if any,  reflected in such financial  statements (or elsewhere in the
Prospectus), or (ii) those which are not material in amount and do not adversely
affect the use made and proposed to be made of such  property by the Company and
its  subsidiaries.  The Company or the  applicable  subsidiary  holds its leased
properties  under  valid and binding  leases,  with such  exceptions  as are not
materially  significant  in  relation  to the  business  of the  Company and its
subsidiaries,  as a whole.  Except as disclosed in the  Prospectus,  the Company
owns or leases all such  properties  as are  necessary to its  operations as now
conducted or as proposed to be conducted.

                  (m)  Since the  respective  dates as of which  information  is
given in the Registration  Statement and Prospectus,  and except as described in
or  specifically  contemplated  by the  Prospectus:  (i)  the  Company  and  its
subsidiaries  have  not  incurred  any  material   liabilities  or  obligations,
indirect,  direct or contingent,  or entered into any material verbal or written
agreement or other  transaction  which is not in the ordinary course of business
or which would  reasonably be expected to result in a material  reduction in the
future  earnings  of the  Company  and its  subsidiaries,  as a whole;  (ii) the
Company  and  its   subsidiaries   have  not  sustained  any  material  loss  or
interference  with their respective  businesses or properties from fire,  flood,
windstorm,  accident or other  calamity,  whether or not  covered by  insurance;
(iii) the Company has not paid or declared any dividends or other  distributions
with respect to its

                                       -5-



capital  stock and the  Company and its  subsidiaries  are not in default in the
payment of principal or interest on any outstanding debt obligations; (iv) there
has not been any change in the  capital  stock  (other than upon the sale of the
Common Shares hereunder and upon the exercise of options and warrants  described
in the Registration  Statement) or indebtedness  material to the Company and its
subsidiaries (other than in the ordinary course of business);  and (v) there has
not been any material adverse change in the condition  (financial or otherwise),
business,  properties, results of operations or prospects of the Company and its
subsidiaries, as a whole.

                  (n) Except as disclosed in or specifically contemplated by the
Prospectus,  the Company and its subsidiaries have sufficient trademarks,  trade
names,  patent  rights,   copyrights,   licenses,   approvals  and  governmental
authorizations  to conduct their businesses as now conducted;  the expiration of
any trademarks,  trade names, patent rights, copyrights,  licenses, approvals or
governmental  authorizations  would not have a  material  adverse  effect on the
condition (financial or otherwise), business, results of operations or prospects
of the Company or its subsidiaries, as a whole; and the Company has no knowledge
of any material infringement by it or its subsidiaries of trademark,  trade name
rights,  patent  rights,  copyrights,  licenses,  trade secret or other  similar
rights of others,  and there is no claim  being made  against the Company or its
subsidiaries regarding trademark, trade name, patent, copyright,  license, trade
secret or other  infringement  which  would  reasonably  be  expected  to have a
material  adverse effect on the condition  (financial or  otherwise),  business,
results of operations or prospects of the Company and its subsidiaries.

                  (o) The  Company  has not been  advised,  and has no reason to
believe, that either it or any of its subsidiaries is not conducting business in
compliance with all applicable laws, rules and regulations of the  jurisdictions
in  which  it  is  conducting  business,   including,  without  limitation,  all
applicable local, state and federal  environmental laws and regulations,  except
where failure to be so in compliance  would not materially  adversely affect the
condition (financial or otherwise), business, results of operations or prospects
of the Company and its subsidiaries, as a whole.

                  (p) The Company and its subsidiaries  have filed all necessary
federal,  state and foreign  income and  franchise  tax returns and have paid or
accrued all taxes shown as due thereon;  and the Company has no knowledge of any
tax  deficiency  which has been or might be asserted or  threatened  against the
Company or its subsidiaries which would reasonably be expected to materially and
adversely  affect the business,  operations or properties of the Company and its
subsidiaries.

                  (q) The  Company  is not an  "investment  company"  within the
meaning of the Investment Company Act of 1940, as amended.

                  (r) The Company has not  distributed  and will not  distribute
prior to the First Closing Date hereinafter  mentioned any offering  material in
connection  with the  offering  and sale of the  Common  Shares  other  than the
Prospectus,  the Registration Statement and the other materials permitted by the
Act.

                  (s)  Each  of  the  Company  and  its  subsidiaries  maintains
insurance  of the types and in the amounts  generally  deemed  adequate  for its
business,  including,  but not  limited  to,  insurance  covering  all  real and
personal  property owned or leased by the Company and its  subsidiaries  against
theft,  damage,  destruction,  acts of vandalism and all other risks customarily
insured against, all of which insurance is in full force and effect.

                                       -6-



                  (t)  Neither  the  Company  nor any of its  subsidiaries  has,
directly  or  indirectly,  at any time  during  the last five years (i) made any
unlawful  contribution to any candidate for public office, or failed to disclose
fully any  contribution  in  violation  of law,  or (ii) made any payment to any
federal or state governmental officer or official,  or other person charged with
similar public or quasi-public duties, other than payments required or permitted
by the laws of the United States or any jurisdiction thereof.

                  (u) The Company  has not taken and will not take,  directly or
indirectly,  any action  designed to or which has  constituted or which might be
reasonably  expected to cause or result in  stabilization or manipulation of the
price of any  security  of the Company to  facilitate  the sale or resale of the
Common Shares.

                  Section 3.  REPRESENTATIONS,  WARRANTIES  AND COVENANTS OF THE
SELLING SHAREHOLDERS.

                  (a) Each of the Selling Shareholders,  including ALA MOANA-95,
L.L.C.,  the Sarah M. Mihaylo  Trust,  the Emily N. Mihaylo  Trust and Thomas C.
Parise  (collectively,  the "Affiliated  Selling  Shareholders")  represents and
warrants to, and agrees with, the several Underwriters that:

                  (i)  Such  Selling  Shareholder  has,  and on  the  First
         Closing Date and Second  Closing Date  hereinafter  mentioned will
         have,  good and valid  title to the Common  Shares  proposed to be
         sold by such  Selling  Shareholder  hereunder on such Closing Date
         and full right,  power and authority to enter into this  Agreement
         and to sell,  assign,  transfer  and deliver  such  Common  Shares
         hereunder, free and clear of all voting trust arrangements, liens,
         encumbrances,   equities,  security  interests,  restrictions  and
         claims  whatsoever;  and upon  delivery  of and  payment  for such
         Common Shares  hereunder,  the Underwriters  will acquire good and
         marketable   title   thereto,   free  and  clear  of  all   liens,
         encumbrances,  equities, claims, restrictions, security interests,
         voting trusts or other defects of title whatsoever.

                  (ii) Such Selling  Shareholder has executed and delivered
         a Power of Attorney and caused to be executed and delivered on its
         behalf a Custody Agreement  (hereinafter  collectively referred to
         as the "Shareholders  Agreement") and in connection  herewith such
         Selling Shareholder  further represents,  warrants and agrees that
         such  Selling  Shareholder  has  deposited  in custody,  under the
         Shareholders Agreement, with the agent named therein (the "Agent")
         as  custodian,  certificates  in  negotiable  form for the  Common
         Shares to be sold hereunder by such Selling  Shareholder,  for the
         purpose of  further  delivery  pursuant  to this  Agreement.  Such
         Selling  Shareholder  agrees that the Common  Shares to be sold by
         such Selling  Shareholder on deposit with the Agent are subject to
         the  interests  of the  Company  and the  Underwriters,  that  the
         arrangements made for such custody are to that extent irrevocable,
         and that the  obligations  of such Selling  Shareholder  hereunder
         shall not be  terminated,  except as provided in this Agreement or
         in  the  Shareholders  Agreement,  by  any  act  of  such  Selling
         Shareholder,  by operation of law, by the death or  incapacity  of
         such Selling  Shareholder or by the occurrence of any other event.
         If the Selling Shareholder should die or become incapacitated,  or
         if any other event should occur, before the delivery of the Common
         Shares hereunder,  the documents  evidencing Common Shares then on
         deposit  with  the  Agent  shall  be  delivered  by the  Agent  in
         accordance with the terms and conditions of

                                       -7-



         this Agreement as if such death, incapacity or other event had not
         occurred,  regardless  of  whether  or not the  Agent  shall  have
         received  notice  thereof.  This  Agreement  and the  Shareholders
         Agreement have been duly executed and delivered by or on behalf of
         such  Selling  Shareholder  and  the  form  of  such  Shareholders
         Agreement has been delivered to you.

                  (iii)  The   performance   of  this   Agreement  and  the
         Shareholders  Agreement and the  consummation of the  transactions
         contemplated  hereby and by the  Shareholders  Agreement  will not
         result in a breach or violation by such Selling Shareholder of any
         of the terms or  provisions  of, or  constitute  a default by such
         Selling Shareholder under, any indenture, mortgage, deed of trust,
         trust (constructive or other), loan agreement,  lease,  franchise,
         license or other  agreement  or  instrument  to which such Selling
         Shareholder is a party or by which such Selling Shareholder or any
         of its properties is bound, any statute, or any judgment,  decree,
         order rule or  regulation of any court or  governmental  agency or
         body  applicable  to  such  Selling  Shareholder  or  any  of  its
         properties.

                  (iv) Such Selling  Shareholder has not taken and will not
         take, directly or indirectly,  any action designed to or which has
         constituted  or which  might  reasonably  be  expected to cause or
         result  in  stabilization  or  manipulation  of the  price  of any
         security  of the Company to  facilitate  the sale or resale of the
         Common Shares.

                  (v)  Each  Preliminary  Prospectus  and  the  Prospectus,
         insofar as it has  related to such  Selling  Shareholder,  has not
         included  any untrue  statement  of a material  fact or omitted to
         state a material fact necessary to make the statements therein not
         misleading  in light of the  circumstances  under  which they were
         made; and neither the  Registration  Statement nor the Prospectus,
         nor any  amendment or  supplement  thereto,  as it relates to such
         Selling  Shareholder,  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.

                  (vi) Such  Selling  Shareholder  is not aware that any of
         the  representations  and  warranties  of the Company set forth in
         Section 2 above is untrue or inaccurate in any material respect.

                  (b) Each of the Selling  Shareholders  agrees with the Company
and the  Underwriters  not to  directly  or  indirectly  offer to sell,  sell or
contract  to  sell or  otherwise  dispose  of any  shares  of  Common  Stock  or
securities  convertible  into or exchangeable for any shares of Common Stock, or
any right to purchase or acquire Common Stock, for a period of 90 days after the
first date that any of the Common  Shares  are  released  by you for sale to the
public,  without the prior written  consent of all of you,  which consent may be
withheld in your sole discretion.

                  Section 4. REPRESENTATIONS AND WARRANTIES OF THE UNDERWRITERS.
You  represent and warrant to the Company and to the Selling  Shareholders  that
the  information  set forth (i) on the cover page of the Prospectus with respect
to price,  underwriting discounts and commissions and terms of offering, (ii) on
the inside front cover of the Prospectus with respect to stabilization and (iii)
under  "Underwriting"  in the  Prospectus was furnished to the Company by and on
behalf of the  Underwriters  for use in connection  with the  preparation of the
Registration  Statement  and  the  Prospectus  and is  correct  in all  material
respects. Montgomery Securities represents and warrants that they have been

                                       -8-



authorized  by each of the  Underwriters  to enter into this  Agreement on their
behalf and to act for them in the manner herein provided.

                  Section 5. PURCHASE,  SALE AND DELIVERY OF COMMON  SHARES.  On
the basis of the  representations,  warranties and agreements  herein contained,
but subject to the terms and conditions herein set forth, (i) the Company agrees
to issue and sell to the Underwriters  2,000,000 of the Firm Common Shares,  and
(ii) the Selling  Shareholders agree,  severally and not jointly, to sell to the
Underwriters  in the  respective  amounts  set forth in  Schedule  B hereto,  an
aggregate  of  850,000  of the  Firm  Common  Shares.  The  Underwriters  agree,
severally  and not  jointly,  to  purchase  from  the  Company  and the  Selling
Shareholders,  respectively,  the number of Firm Common Shares  described below.
The  purchase  price per  share to be paid by the  several  Underwriters  to the
Company  and to the  Selling  Shareholders,  respectively,  shall be $_____  per
share.

                  The obligation of each  Underwriter to the Company shall be to
purchase  from the  Company  that  number of full  shares  which  (as  nearly as
practicable,  as determined by you) bears to 2,850,000 in the same proportion as
the number of shares set forth opposite the name of such Underwriter in Schedule
A hereto bears to the total number of Firm Common Shares. The obligation of each
Underwriter  to the Selling  Shareholders  shall be to purchase from the Selling
Shareholders  that number of full  shares  which (as nearly as  practicable,  as
determined  by you) bears to 2,850,000 in the same  proportion  as the number of
shares set forth  opposite  the name of such  Underwriter  in  Schedule A hereto
bears to the total number of Firm Common Shares.

                  Delivery  of  certificates  for the Firm  Common  Shares to be
purchased by the  Underwriters and payment therefor shall be made at the offices
of Montgomery Securities,  600 Montgomery Street, San Francisco,  California (or
such other  place as may be agreed upon by the Company and you) at such time and
date,  not later than the third (or,  if the Firm Common  Shares are priced,  as
contemplated by Rule 15c6-1(c) of the Exchange Act, after 4:30 P.M.  Washington,
D.C.  time,  the fourth) full  business day following the first date that any of
the  Common  Shares are  released  by you for sale to the  public,  as you shall
designate  by at least 48 hours prior  notice to the Company (or such other time
and date,  not later than one week  after such third or fourth,  as the case may
be, full business day as may be agreed upon by the Company and the Underwriters)
(the  "First  Closing  Date"),   provided,   however,  that  in  the  event  the
Registration  Statement is amended or the Prospectus is supplemented between the
date hereof and the First  Closing  Date,  you shall have the right to delay the
First  Closing  Date to a date (not  later  than one week  after  such  third or
fourth,  as the case may be, full business day) that shall allow you  sufficient
time to distribute the Prospectus as amended or  supplemented.  (As used herein,
"business  day"  means a day on which the New York  Stock  Exchange  is open for
trading  and on which  banks in New  York  are  open  for  business  and are not
permitted by law or executive order to be closed.)

                  Delivery of  certificates  for the Firm Common Shares shall be
made by or on behalf of the  Company and the  Selling  Shareholders  to you with
respect to the Firm  Common  Shares to be sold by the Company and by the Selling
Shareholders  against payment by you of the purchase price therefor by certified
or official  bank  checks  payable in next day funds to the order of the Company
and of the Agent in proportion to the number of Firm Common Shares to be sold by
the Company and the Selling Shareholders, respectively. The certificates for the
Firm Common Shares shall be registered  in such names and  denominations  as you
shall have  requested at least two full business days prior to the First Closing
Date, and shall be made available for checking and packaging on the business day
preceding the First Closing Date at a location in New York,  New York, as may be
designated by you.

                                       -9-



Time shall be of the essence,  and  delivery at the time and place  specified in
this Agreement is a further condition to the obligations of the Underwriters.

                  In addition,  on the basis of the representations,  warranties
and agreements herein contained,  but subject to the terms and conditions herein
set forth, the Selling  Shareholder set forth in Schedule B hereto hereby grants
an option to the several Underwriters to purchase, severally and not jointly, up
to an  aggregate of 427,500  Optional  Common  Shares at the purchase  price per
share to be paid for the Firm  Common  Shares,  for use solely in  covering  any
over-allotments  made by you for the account of the Underwriters in the sale and
distribution  of the Firm Common  Shares.  The option  granted  hereunder may be
exercised  at any time (but not more than  once)  within 30 days after the first
date that any of the Common  Shares are  released by you for sale to the public,
upon notice by you to the Company and the Selling Shareholders setting forth the
aggregate  number of Optional  Common  Shares as to which the  Underwriters  are
exercising the option, the names and denominations in which the certificates for
such  shares  are to be  registered  and  the  time  and  place  at  which  such
certificates will be delivered.  Such time of delivery (which may not be earlier
than the First Closing Date),  being herein  referred to as the "Second  Closing
Date," if at any time  other  than the First  Closing  Date  shall be three full
business days after delivery of such notice of exercise.  The number of Optional
Common  Shares  to be  purchased  by each  Underwriter  shall be  determined  by
multiplying  the  number of  Optional  Common  Shares to be sold by the  Selling
Shareholders pursuant to such notice of exercise by a fraction, the numerator of
which is the number of Firm Common Shares to be purchased by such Underwriter as
set  forth  opposite  its name in  Schedule  A and the  denominator  of which is
2,850,000  (subject  to such  adjustments  to  eliminate  any  fractional  share
purchases as you in your  discretion  may make).  Certificates  for the Optional
Common Shares will be made  available for checking and packaging on the business
day  preceding the Second  Closing Date at a location in New York,  New York, as
may be designated by you. The manner of payment for and delivery of the Optional
Common Shares shall be the same as for the Firm Common Shares purchased from the
Selling Shareholders as specified in the two preceding  paragraphs.  At any time
before lapse of the option,  you may cancel such option by giving written notice
of such cancellation to the Selling Shareholders.  If the option is cancelled or
expires  unexercised in whole or in part, the Company will deregister  under the
Act the number of Option Shares as to which the option has not been exercised.

                  Subject to the terms and conditions  hereof,  the Underwriters
propose to make a public  offering  of their  respective  portions of the Common
Shares as soon after the effective date of the Registration Statement as in your
judgment is advisable  and at the public  offering  price set forth on the cover
page of and on the terms set forth in the Prospectus.

                  Section 6. COVENANTS OF THE COMPANY. The Company covenants and
agrees that:

                  (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.  If the Registration Statement has become or becomes effective
pursuant  to Rule  430A of the  Rules  and  Regulations,  or the  filing  of the
Prospectus is otherwise required under Rule 424(b) of the Rules and Regulations,
the  Company  will file the  Prospectus,  properly  completed,  pursuant  to the
applicable paragraph of Rule 424(b) of the Rules and Regulations within the time
period  prescribed and will provide evidence  satisfactory to you of such timely
filing.  The Company will  promptly  advise you in writing (i) of the receipt of
any  comments  of the  Commission,  (ii) of any  request of the  Commission  for
amendment of or supplement to the Registration Statement (either before or after
it becomes  effective),  any  Preliminary  Prospectus  or the  Prospectus or for
additional information, (iii) when the Registration Statement shall have become

                                      -10-



effective  and  (iv)  of the  issuance  by the  Commission  of  any  stop  order
suspending the effectiveness of the Registration Statement or of the institution
of any proceedings for that purpose. If the Commission shall enter any such stop
order at any time,  the Company  will use its best efforts to obtain the lifting
of such order at the  earliest  possible  moment.  The Company will not file any
amendment or supplement to the Registration Statement (either before or after it
becomes  effective),  any Preliminary  Prospectus or the Prospectus of which you
have not been furnished with a copy a reasonable time prior to such filing or to
which you reasonably  object or which is not in compliance  with the Act and the
Rules and Regulations.

                  (b) The Company  will  prepare  and file with the  Commission,
promptly upon your request,  any amendments or  supplements to the  Registration
Statement or the Prospectus which in your judgment may be necessary or advisable
to enable the Underwriters to continue the distribution of the Common Shares and
will use its best  efforts to cause the same to become  effective as promptly as
possible.  The Company will fully and  completely  comply with the provisions of
Rule 430A of the Rules and Regulations with respect to information  omitted from
the Registration Statement in reliance upon such Rule.

                  (c) If at any time within the nine-month period referred to in
Section  10(a)(3) of the Act during  which a  prospectus  relating to the Common
Shares is required to be delivered  under the Act any event occurs,  as a result
of which the Prospectus,  including any amendments or supplements, would include
an 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, or if it is necessary at any time to amend the Prospectus, including
any  amendments  or  supplements,  to  comply  with  the  Act or the  Rules  and
Regulations,  the Company  will  promptly  advise you thereof and will  promptly
prepare  and file with the  Commission,  at its own  expense,  an  amendment  or
supplement  which will  correct  such  statement  or omission or an amendment or
supplement  which will effect such  compliance  and will use its best efforts to
cause  the  same to  become  effective  as soon as  possible;  and,  in case any
Underwriter is required to deliver a prospectus  after such  nine-month  period,
the Company upon request, but at the expense of such Underwriter,  will promptly
prepare such  amendment or  amendments  to the  Registration  Statement and such
Prospectus or  Prospectuses  as may be necessary to permit  compliance  with the
requirements of Section 10(a)(3) of the Act.

                  (d) As soon as  practicable,  but not later than 45 days after
the end of the first quarter ending after one year following the "effective date
of the  Registration  Statement"  (as  defined  in Rule  158(c) of the Rules and
Regulations),  the Company will make generally available to its security holders
an  earnings  statement  (which  need not be  audited)  which will  satisfy  the
provisions of the last paragraph of Section 11(a) of the Act.

                  (e) During such period as a  prospectus  is required by law to
be delivered in connection with sales by an Underwriter or dealer,  the Company,
at its  expense,  but only for the  nine-month  period  referred  to in  Section
10(a)(3) of the Act, will furnish to you and the Selling Shareholders or mail to
your order copies of the Registration Statement, the Prospectus, the Preliminary
Prospectus and all amendments and supplements to any such documents in each case
as soon as available and in such quantities as you and the Selling  Shareholders
may request, for the purposes contemplated by the Act.

                  (f) The Company shall  cooperate  with you and your counsel in
order to  qualify  or  register  the  Common  Shares  for sale  under (or obtain
exemptions from the application of) the blue sky laws of such  jurisdictions  as
you designate, will comply with such laws and will continue such

                                      -11-



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

                  (g) During the period of five  years  hereafter,  the  Company
will  furnish to you:  (i) as soon as  practicable  after the end of each fiscal
year, copies of the Annual Report of the Company containing the balance sheet of
the  Company  as of the close of such  fiscal  year and  statements  of  income,
shareholders'  equity  and cash  flows for the year then  ended and the  opinion
thereon  of the  Company's  independent  public  accountants;  (ii)  as  soon as
practicable  after the filing thereof,  copies of each proxy  statement,  Annual
Report on Form 10-K,  Quarterly Report on Form 10-Q, Report on Form 8-K or other
report  filed by the Company  with the  Commission,  the NASD or any  securities
exchange; and (iii) as soon as available,  copies of any report or communication
of the Company mailed generally to holders of its Common Stock.

                  (h) During the period of 90 days after the first date that any
of the Common  Shares are  released by you for sale to the  public,  without the
prior written  consent of all of you, which consent may be withheld in your sole
discretion, the Company will not, directly or indirectly (other than pursuant to
outstanding  stock  options and warrants  disclosed in the  Prospectus),  issue,
offer, sell, grant options to purchase (other than the grant of options pursuant
to stock option plans  existing on the date hereof) or otherwise  dispose of any
of the Company's equity  securities or any other securities  convertible into or
exchangeable for its Common Stock or other equity security.

                  (i) The Company will apply the net proceeds of the sale of the
Common Shares sold by it  substantially  in accordance with its statements under
the caption "Use of Proceeds" in the Prospectus.

                  (j) The  Company  will  use its best  efforts  to  qualify  or
register its Common Stock for sale in non-issuer  transactions  under (or obtain
exemptions from the application of) the Blue Sky laws of the State of California
(and thereby  permit market  making  transactions  and secondary  trading in the
Company's  Common Stock in California),  and will comply with such Blue Sky laws
and will continue such  qualifications,  registrations  and exemptions in effect
for a period of five years after the date hereof.

                  You  may,  in your  sole  discretion,  waive  in  writing  the
performance  by the  Company of any one or more of the  foregoing  covenants  or
extend the time for their performance.

                  Section   7.   PAYMENT  OF   EXPENSES.   Whether  or  not  the
transactions  contemplated  hereunder are consummated or this Agreement  becomes
effective  or is  terminated,  the Company  and,  unless  otherwise  paid by the
Company,  the Selling  Shareholders agree to pay in such proportions as they may
agree upon among themselves all costs,  fees and expenses incurred in connection
with the performance of their  obligations  hereunder and in connection with the
transactions  contemplated hereby,  including without limiting the generality of
the  foregoing,  (i) all  expenses  incident to the issuance and delivery of the
Common Shares (including all printing and engraving costs), (ii) all fees

                                      -12-



and expenses of the registrar and transfer  agent of the Common Stock and of the
Agent,  (iii) all necessary issue,  transfer and other stamp taxes in connection
with the issuance and sale of the Common  Shares to the  Underwriters,  (iv) all
fees and expenses of the Company's counsel (including fees and expenses relating
to the representation of the Selling  Shareholders by the Company's counsel) and
the Company's  independent  accountants,  (v) all costs and expenses incurred in
connection with the preparation,  printing, filing, shipping and distribution of
the  Registration  Statement,  each  Preliminary  Prospectus  and the Prospectus
(including  all  exhibits  and  financial  statements)  and all  amendments  and
supplements   provided  for  herein,   this   Agreement,   any  Agreement  Among
Underwriters,  any Selected Dealers Agreement, any Underwriters'  Questionnaire,
any Underwriters' Power of Attorney and the Blue Sky memoranda,  (vi) all filing
fees,  attorneys' fees and expenses  incurred by the Company or the Underwriters
in connection with  qualifying or registering (or obtaining  exemptions from the
qualification or registration of) all or any part of the Common Shares for offer
and sale under state Blue Sky or Canadian  securities laws, (vii) the filing fee
of the National  Association of Securities  Dealers,  Inc., and (viii) all other
fees, costs and expenses  referred to in Item 14 of the Registration  Statement.
The  Underwriters may deem the Company to be the primary obligor with respect to
all  costs,  fees and  expenses  to be paid by the  Company  and by the  Selling
Shareholders.  Except as  provided in this  Section 7,  Section 9 and Section 11
hereof, the Underwriters shall pay all of their own expenses, including the fees
and  disbursements of their counsel  (excluding those relating to qualification,
registration or exemption  under the state Blue Sky or Canadian  securities laws
and the Blue Sky memoranda  referred to above).  This Section 7 shall not affect
any agreements  relating to the payment of expenses  between the Company and the
Selling Shareholders.

                  The   Selling   Shareholders   will   pay   (directly   or  by
reimbursement)  all fees  and  expenses  incident  to the  performance  of their
obligations under this Agreement which are not otherwise  specifically  provided
for herein,  including  but not limited to (i) any fees and  expenses of counsel
for such Selling  Shareholders  (other than fees and  expenses of the  Company's
counsel);  and (ii) all expenses and taxes  incident to the sale and delivery of
the Common Shares to be sold by such Selling  Shareholders  to the  Underwriters
hereunder.

                  Section 8. CONDITIONS OF THE OBLIGATIONS OF THE  UNDERWRITERS.
The  obligations  of the several  Underwriters  to purchase and pay for the Firm
Common  Shares on the First  Closing Date and the Optional  Common Shares on the
Second Closing Date shall be subject to the accuracy of the  representations and
warranties  on the part of the Company and the Selling  Shareholders  herein set
forth as of the date  hereof  and as of the  First  Closing  Date or the  Second
Closing Date,  as the case may be, to the accuracy of the  statements of Company
officers and the Selling Shareholders made pursuant to the provisions hereof, to
the performance by the Company and the Selling  Shareholders of their respective
obligations hereunder, and to the following additional conditions:

                  (a) The Registration Statement shall have become effective not
later than 5:00 P.M. (or, in the case of a registration statement filed pursuant
to Rule 462(b) of the Rules and Regulations  relating to the Common Shares,  not
later than 10:00 P.M.), Washington, D.C. time, on the date of this Agreement, or
at such later time as shall have been  consented to by you; if the filing of the
Prospectus,  or any supplement  thereto,  is required pursuant to Rule 424(b) of
the Rules and  Regulations,  the Prospectus  shall have been filed in the manner
and within the time period required by Rule 424(b) of the Rules and Regulations;
and prior to such Closing Date, no stop order  suspending the  effectiveness  of
the  Registration  Statement  shall have been issued and no proceedings for that
purpose  shall have been  instituted or shall be pending or, to the knowledge of
the Company,  the Selling  Shareholders  or you,  shall be  contemplated  by the
Commission; and any request of the Commission for inclusion of

                                      -13-



additional information in the Registration Statement,  or otherwise,  shall have
been complied with to your satisfaction.

                  (b) You shall be satisfied that since the respective  dates as
of which information is given in the Registration Statement and Prospectus,  (i)
there shall not have been any change in the capital  stock (other than  pursuant
to the exercise of outstanding options and warrants disclosed in the Prospectus)
of the  Company  or  any of its  subsidiaries  or  any  material  change  in the
indebtedness  (other than in the ordinary  course of business) of the Company or
any of its  subsidiaries,  (ii)  except  as set  forth  or  contemplated  by the
Registration  Statement  or  the  Prospectus,  no  material  verbal  or  written
agreement  or other  transaction  shall have been entered into by the Company or
any of its  subsidiaries,  which is not in the  ordinary  course of  business or
which would  reasonably  be expected  to result in a material  reduction  in the
future  earnings of the Company  and its  subsidiaries,  (iii) no loss or damage
(whether  or  not  insured)  to  the  property  of  the  Company  or  any of its

prospects  of the Company and its  subsidiaries,  (iv) no legal or  governmental
action,  suit or  proceeding  affecting  the Company or any of its  subsidiaries

instituted or threatened  and (v) there shall not have been any material  change
in the condition  (financial or  otherwise),  business,  management,  results of
operations  or  prospects  of the  Company and its  subsidiaries  which makes it
impractical or inadvisable in your judgment to proceed with the public  offering
or purchase the Common Shares as contemplated hereby.

                  (c) There  shall have been  furnished  to you on each  Closing
Date, in form and substance  satisfactory to you, except as otherwise  expressly

         included in such  documents  as to which such counsel need express
         no opinion), when they were filed with the Commission, complied as
         to form in all  material  respects  with the  requirements  of the

         this Agreement by the Company or the performance by the Company of
         its obligations  set forth in this Agreement,  except such as have
         been  obtained  and are in full force and effect under the Act and

         under, any agreement,  mortgage,  deed of trust, lease, franchise,
         license,  indenture,  permit  or  other  instrument  known to such
         counsel to which the Company or any of its subsidiaries is a party
         or by which the Company or any of its  subsidiaries  or any of its
         or their  property  may be bound or affected  which is material to
         the Company and its  subsidiaries,  as a whole,  or violate any of
         the  provisions  of the articles of  incorporation  or bylaws,  or
         other  organizational  documents,  of  the  Company  or any of its
         subsidiaries  or, so far as is known to such counsel,  violate any
         statute,  judgment, decree, order, rule or regulation of any court
         or governmental  body having  jurisdiction over the Company or any
         of its subsidiaries or any of its or their property;

         incorporation or bylaws,  none of the Material  Subsidiaries is in
         violation of its articles of  incorporation  or, to such counsel's
         knowledge,  bylaws or other organizational documents, and, to such
         counsel's   knowledge,   neither  the  Company  nor  any  Material
         Subsidiary is in

                                      -16-



         breach  of or  default  with  respect  to  any  provision  of  any
         agreement,  mortgage,  deed of trust, lease,  franchise,  license,

         Registration  Statement  or the  Company  Form  10-K to which  the
         Company or any such subsidiary is a party or by which it or any of
         its properties may be bound or affected, except where such default
         would  not  materially   adversely  affect  the  Company  and  its
         subsidiaries, taken as a whole;

                  (10)  To  such   counsel's   knowledge,   no  holders  of
         securities  of the Company  have rights which have not been waived
         or  fulfilled  to the  registration  of shares of Common  Stock or
         other  securities,  because  of the  filing  of  the  Registration
         Statement by the Company or the offering contemplated hereby;

                  (11) To such counsel's knowledge,  this Agreement and the
         Shareholders  Agreement  have been duly  authorized,  executed and
         delivered by or on behalf of each of the Selling Shareholders; the
         Agent has been duly and validly authorized to act as the custodian
         of the Common Shares to be sold by each such Selling  Shareholder;
         and, to such  counsel's  knowledge,  the execution and delivery of
         this  Agreement  and the  Shareholders  Agreement  by each Selling
         Shareholder  and the  performance by the Selling  Shareholders  of
         their obligations set forth herein and therein, will not result in
         a breach  of,  or  constitute  a  default  under,  any  indenture,
         mortgage,  deed of trust,  trust  (constructive  or  other),  loan
         agreement,  lease,  franchise,   license  or  other  agreement  or
         instrument to which any of the Selling  Shareholders is a party or
         by  which  any  of  the  Selling  Shareholders  or  any  of  their
         properties  may be bound  and  which is  material  to any  Selling
         Shareholder, or violate any statute, judgment, decree, order, rule
         or regulation  known to such counsel of any court or  governmental
         body having  jurisdiction over any of the Selling  Shareholders or
         any of  their  properties;  and to such  counsel's  knowledge,  no
         approval, authorization, order or consent of any court, regulatory
         body, administrative agency or other governmental body is required
         for  the  execution   and  delivery  of  this   Agreement  or  the
         Shareholders   Agreement  or  the   performance   by  the  Selling
         Shareholders  of their  obligations  set forth in this  Agreement,
         except such as have been obtained and are in full force and effect
         under the Act and such as may be  required  under the rules of the
         NASD and applicable Blue Sky laws;

                  (12)   To   such   counsel's   knowledge,   the   Selling
         Shareholders  have full right,  power and  authority to enter into
         this  Agreement  and  the  Shareholders  Agreement  and  to  sell,
         transfer and deliver the Common  Shares to be sold on such Closing
         Date by such  Selling  Shareholders  hereunder  and good and valid
         title to such Common Shares so sold,  free and clear of all liens,
         encumbrances,  equities, claims, restrictions, security interests,
         voting  trusts,  or other  defects of title  whatsoever,  has been
         transferred  to the  Underwriters  (whom  counsel may assume to be
         bona  fide  purchasers)  who have  purchased  such  Common  Shares
         hereunder; and

                  (13) To such counsel's knowledge,  this Agreement and the
         Shareholders Agreement are valid and binding agreements of each of
         the Selling  Shareholders in accordance with their terms except as
         enforceability  may be limited by  general  equitable  principles,
         bankruptcy, insolvency,  reorganization,  moratorium or other laws
         affecting  creditors'  rights generally and except with respect to
         those provisions relating

                                      -17-



         to indemnities or contributions  for liabilities under the Act, as
         to which no opinion need be expressed.

                  In  rendering  such  opinion,  such counsel may rely as to the
         matters set forth in  paragraphs  (11),  (12) and (13),  on opinions of
         other counsel  retained by the Selling  Shareholders,  as to matters of
         local or regulatory  law, on opinions of local or  regulatory  counsel,
         and as to matters of fact, on certificates of the Selling  Shareholders
         and of officers of the Company and of governmental  officials, in which
         case  their  opinion  is to state  that  they are so doing and that the
         Underwriters  are justified in relying on such opinions or certificates
         and copies of said  opinions or  certificates  are to be  delivered  to
         counsel  for the  Underwriters.  Such  counsel  shall  also  include  a
         statement  to the  effect  that  nothing  has  come to  such  counsel's
         attention  that would lead such  counsel to believe  that either at the
         effective  date  of the  Registration  Statement  or at the  applicable
         Closing Date the Registration Statement or the Prospectus,  or any such
         amendment  or  supplement  (other  than the  financial  statements  and
         schedules and other financial or statistical data set forth therein, as
         to which such  counsel  need  express no belief),  contains  any untrue
         statement of a material fact or omits to state a material fact required
         to be stated  therein or necessary to make the  statements  therein not
         misleading;

                  (ii) Such  opinion or opinions of  Pillsbury  Madison & Sutro,
         counsel  for the  Underwriters,  dated  the First  Closing  Date or the
         Second  Closing  Date,  as  the  case  may  be,  with  respect  to  the
         incorporation  of  the  Company,   the  sufficiency  of  all  corporate
         proceedings  and other legal matters  relating to this  Agreement,  the
         validity  of the Common  Shares,  the  Registration  Statement  and the
         Prospectus and other related matters as you may reasonably require, and
         the Company and the Selling  Shareholders  shall have furnished to such
         counsel such documents and shall have exhibited to them such papers and
         records as they may reasonably request for the purpose of enabling them
         to pass upon such  matters.  In  connection  with such  opinions,  such
         counsel may rely on  representations or certificates of officers of the
         Company and governmental officials.

                  (iii) A certificate of the Company executed by the Chairman of
         the Board or President and the chief financial or accounting officer of
         the Company,  dated the First Closing Date or the Second  Closing Date,
         as the case may be, to the effect that:

                  (1) The representations and warranties of the Company set
         forth in Section 2 of this  Agreement  are true and  correct as of
         the date of this Agreement and as of the First Closing Date or the
         Second  Closing  Date,  as the case may be,  and the  Company  has
         complied with all the  agreements and satisfied all the conditions
         on its  part to be  performed  or  satisfied  on or  prior to such
         Closing Date;

                  (2) The Commission has not issued any order preventing or
         suspending the use of the Prospectus or any Preliminary Prospectus
         filed as a part of the  Registration  Statement  or any  amendment
         thereto;  no  stop  order  suspending  the  effectiveness  of  the
         Registration  Statement  has been  issued;  and to the best of the
         knowledge  of the  respective  signers,  no  proceedings  for that
         purpose have been instituted or are pending or contemplated  under
         the Act;

                  (3) Each of the respective signers of the certificate has
         carefully examined the Registration  Statement and the prospectus;
         to the best of his knowledge,  the Registration  Statement and the
         Prospectus and any amendments or supplements thereto

                                      -18-



         contain all statements required to be stated therein regarding the
         Company  and  its  subsidiaries;   and  neither  the  Registration
         Statement  nor the  Prospectus  nor any  amendment  or  supplement
         thereto  includes any untrue statement of a material fact or omits
         to state  any  material  fact  required  to be stated  therein  or
         necessary  to make the  statements  therein,  in the  light of the
         circumstances under which they were made, not misleading;

                  (4) Since  the  initial  date on which  the  Registration
         Statement was filed, no agreement, written or oral, transaction or
         event  has  occurred  which  should  have  been  set  forth  in an
         amendment to the  Registration  Statement or in a supplement to or
         amendment of any prospectus which has not been disclosed in such a
         supplement or amendment;

                  (5) Since the respective dates as of which information is
         given in the Registration Statement and the Prospectus, and except
         as disclosed in or contemplated  by the Prospectus,  there has not
         been any material  adverse change or a development  which would be
         reasonably  likely to result in a material  adverse  change in the
         condition (financial or otherwise),  business, properties, results
         of operations  or management of the Company and its  subsidiaries,
         as  a  whole;  and  no  legal  or  governmental  action,  suit  or
         proceeding is pending or threatened  against the Company or any of
         its  subsidiaries  which  is  material  to  the  Company  and  its
         subsidiaries, as a whole, whether or not arising from transactions
         in the ordinary course of business,  or which may adversely affect
         the transactions contemplated by this Agreement;  since such dates
         and except as so  disclosed,  neither  the  Company nor any of its
         subsidiaries  has entered into any verbal or written  agreement or
         other  transaction which is not in the ordinary course of business
         or which  would  reasonably  be  expected  to result in a material
         reduction  in the future  earnings of the Company or incurred  any
         material liability or obligation,  direct, contingent or indirect,
         made any change in its capital stock (except  pursuant to exercise
         of stock  options and warrants as  disclosed  in the  Prospectus),
         made any material  change in its short-term debt or funded debt or
         repurchased  or otherwise  acquired any of the  Company's  capital
         stock;  and the Company has not declared or paid any dividend,  or
         made any other  distribution,  upon its outstanding  capital stock
         payable  to  shareholders  of record on a date  prior to the First
         Closing Date or Second Closing Date; and

                  (6) Since the respective dates as of which information is
         given in the Registration  Statement and the Prospectus and except
         as disclosed in or contemplated by the Prospectus, the Company and
         its  subsidiaries  have not sustained a material loss or damage by
         strike,  fire,  flood,  windstorm,   accident  or  other  calamity
         (whether or not insured).

                  (iv) On the date before this Agreement is executed and also on
         the First Closing Date and the Second  Closing Date a letter  addressed
         to you from Ernst & Young LLP, independent  accountants,  the first one
         to be dated the day before the date of this  Agreement,  the second one
         to be dated the First Closing Date and the third one (in the event of a
         Second  Closing)  to be dated  the  Second  Closing  Date,  in form and
         substance satisfactory to you.

                  (v) On the First  Closing Date or the Second  Closing Date, as
         the case may be, a  certificate,  dated such Closing Date and addressed
         to you, signed by or on behalf of each of

                                      -19-



         the Selling  Shareholders  to the effect that the  representations  and
         warranties of such Selling  Shareholder  in this Agreement are true and
         correct,  as if  made at and as of the  First  Closing  Date or  Second
         Closing  Date,  as the case may be, and such  Selling  Shareholder  has
         complied with all the  agreements  and satisfied all the  conditions on
         its part to be performed or satisfied  prior to the First  Closing Date
         or Second Closing Date, as the case may be.

                  (vi) On or before the First  Closing  Date,  letters from each
         officer of the  Company,  in form and  substance  satisfactory  to you,
         confirming  that for a period of 90 days  after the first date that any
         of the Common  Shares are released by you for sale to the public,  such
         person  will  not  directly  or  indirectly  sell or  offer  to sell or
         otherwise dispose of any shares of Common Stock or any right to acquire
         such shares  without  the prior  written  consent of all of you,  which
         consent may be withheld your sole discretion.

                  All such opinions,  certificates,  letters and documents shall
be in compliance with the provisions hereof only if they are satisfactory to you
and to  Pillsbury  Madison & Sutro,  counsel for the  Underwriters.  The Company
shall  furnish  you with  such  manually  signed  or  conformed  copies  of such
opinions,  certificates,  letters and documents as you request.  Any certificate
signed by any officer of the Company and  delivered to you or to counsel for the
Underwriters  shall be deemed to be a representation and warranty by the Company
to the Underwriters as to the statements made therein.

                  If any condition to the Underwriters' obligations hereunder to
be satisfied  prior to or at the First  Closing Date is not so  satisfied,  this
Agreement  at your  election  will  terminate  upon  notification  by you to the
Company  and the  Selling  Shareholders  without  liability  on the  part of any
Underwriter or the Company or the Selling  Shareholders  except for the expenses
to be paid or reimbursed by the Company and by the Selling Shareholders pursuant
to  Sections  7 and 9 hereof and  except to the  extent  provided  in Section 11
hereof.

                  Section   9.   REIMBURSEMENT   OF   UNDERWRITERS'    EXPENSES.
Notwithstanding  any  other  provisions  hereof,  if  this  Agreement  shall  be
terminated  by  you  pursuant  to  Section  8  hereof,  or if  the  sale  to the
Underwriters  of the  Common  Shares at the  First  Closing  is not  consummated
because of any  refusal,  inability or failure on the part of the Company or the
Selling  Shareholders  to perform  any  agreement  herein or to comply  with any
provision hereof, the Company agrees to reimburse you and the other Underwriters
upon  demand for all  out-of-pocket  expenses  that  shall have been  reasonably
incurred by you and them in connection  with the proposed  purchase and the sale
of the Common  Shares,  including but not limited to fees and  disbursements  of
counsel,  printing  expenses,  travel expenses,  postage,  telegraph charges and
telephone  charges  relating  directly  to  the  offering  contemplated  by  the
Prospectus.  Any such termination shall be without liability of any party to any
other party except that the provisions of this Section, Section 7 and Section 11
shall at all times be effective and shall apply.

                  Section 10. EFFECTIVENESS OF REGISTRATION STATEMENT.  You, the
Company and the Selling  Shareholders  will use your, its and their best efforts
to cause the Registration Statement to become effective, to prevent the issuance
of any stop order suspending the  effectiveness  of the  Registration  Statement
and,  if such stop order be issued,  to obtain as soon as  possible  the lifting
thereof.

                  Section 11.  INDEMNIFICATION.

                  (a)  The   Company   and  each  of  the   Affiliated   Selling
Shareholders,  jointly and severally,  agree to indemnify and hold harmless each
Underwriter  and each person,  if any, who controls any  Underwriter  within the
meaning of the Act against any losses, claims, damages, liabilities or expenses,
joint or  several,  to which such  Underwriter  or such  controlling  person may
become  subject,  under the Act,  the  Exchange  Act, or other  federal or state
statutory  law or  regulation,  or at  common  law or  otherwise  (including  in
settlement of any  litigation,  if such  settlement is effected with the written
consent of the Company), insofar as such losses, claims, damages, liabilities or
expenses (or actions in respect thereof as  contemplated  below) arise out of or
are based upon any untrue  statement or alleged untrue statement of any material
fact contained in the Registration Statement,  any Preliminary  Prospectus,  the
Prospectus, or any amendment or supplement thereto, or arise out of or are based
upon the  omission or alleged  omission to state in any of them a material  fact
required to be stated therein or necessary to make the statements in any of them
not  misleading,  or  arise  out of or are  based  in  whole  or in  part on any
inaccuracy in the  representations  and warranties of the Company or the Selling
Shareholders  contained  herein or any  failure of the  Company  or the  Selling
Shareholders to perform their respective obligations hereunder or under law; and
will reimburse each Underwriter and each such  controlling  person for any legal
and other expenses  reasonably  incurred by such Underwriter or such controlling
person in connection with investigating,  defending,  settling,  compromising or
paying any such loss, claim,  damage,  liability,  expense or action;  provided,
however,  that neither the Company nor the Affiliated Selling  Shareholders will
be liable in any such case to the  extent  that any such  loss,  claim,  damage,
liability  or  expense  arises out of or is based  upon an untrue  statement  or
alleged  untrue   statement  or  omission  or  alleged   omission  made  in  the
Registration  Statement,  any  Preliminary  Prospectus,  the  Prospectus  or any
amendment or  supplement  thereto in reliance  upon and in  conformity  with the
information  furnished to the Company pursuant to Section 4 hereof; and provided
further, that with respect to any untrue statement or omission or alleged untrue
statement  or  omission  made in the  Registration  Statement,  any  Preliminary
Prospectus,  the  Prospectus,  or any  amendment  or  supplement  thereto,  each
Affiliated  Selling  Shareholder shall not be liable under this paragraph for an
amount in excess of the proceeds received by the Affiliated Selling  Shareholder
for the  Common  Shares  sold  by such  Affiliated  Selling  Shareholder  to the
Underwriters;  and provided further, that the indemnity provided in this Section
11(a) with respect to any Preliminary  Prospectus shall not inure to the benefit
of any Underwriter from whom the person asserting any losses,  claims,  charges,
liabilities  or  litigation  based upon any untrue  statement or alleged  untrue
statement of any material fact or omission or alleged  omission to state therein
a material fact, if a copy of the  Prospectus in which such untrue  statement or
alleged untrue statement or omission was corrected has not been sent or given to
such person  within the time  required  by the Act and the Rule and  Regulations
thereunder,  unless such failure is the result of  noncompliance  by the Company
with Section  6(e) hereof;  and provided  further,  that no  Affiliated  Selling
Shareholder  shall be  liable in any case  pursuant  to this  Section  11 to the
extent any such loss, claim,  damage or liability arises out of or is based upon
an untrue  statement or omission or alleged  omission  made in the  Registration
Statement,  any  Preliminary  Prospectus,  the  Prospectus,  or any amendment or
supplement  thereto,  in  reliance  upon  and  in  conformity  with  information
furnished  to the  Company  in  writing by any other  Selling  Shareholder;  and
provided further,  that no Affiliated  Selling  Shareholder shall be required to
provide  indemnification  or  reimbursement  hereunder  until the Underwriter or
control person seeking  indemnification or reimbursement shall have first made a
claim  therefor  against  the  Company  and such  claim has not been paid by the
Company for a period of not less than 45 days.  The  Company and the  Affiliated
Selling  Shareholders  may agree, as among  themselves,  as to their  respective
amounts of such liability for which they each shall be responsible.  In addition
to their  other  obligations  under this  Section  11(a),  the  Company  and the
Affiliated Selling Shareholders agree that, as an interim measure during the

                                      -21-



pendency  of any  claim,  action,  investigation,  inquiry  or other  proceeding
arising out of or based upon any statement or omission, or any alleged statement
or omission,  or any  inaccuracy in the  representations  and  warranties of the
Company or the Selling Shareholders herein or failure to perform its obligations
hereunder,  all as described in this Section  11(a),  they will  reimburse  each
Underwriter  on a quarterly  basis for all  reasonable  legal or other  expenses
incurred in connection with  investigating or defending any such claim,  action,
investigation,  inquiry or other  proceeding,  notwithstanding  the absence of a
judicial  determination as to the propriety and  enforceability of the Company's
or the Affiliated Selling Shareholders' obligation to reimburse each Underwriter
for such expenses and the possibility  that such payments might later be held to
have been improper by a court of competent jurisdiction.  To the extent that any
such  interim  reimbursement  payment  is so held to have  been  improper,  each
Underwriter  shall  promptly  return it to the Company  together with  interest,
compounded daily, determined on the basis of the prime rate (or other commercial
lending rate for borrowers of the highest credit  standing)  announced from time
to  time  by Bank  of  America  National  Trust  and  Savings  Association,  San
Francisco,  California  (the  "Prime  Rate").  Any  such  interim  reimbursement
payments  which are not made to an  Underwriter  within 30 days of a request for
reimbursement,  shall  bear  interest  at the  Prime  Rate from the date of such
request. This indemnity agreement will be in addition to any liability which the
Company or the Selling Shareholders may otherwise have.

                  (b)  Each  Underwriter  will  severally   indemnify  and  hold
harmless the Company, each of its directors, each of its officers who signed the
Registration  Statement,  the Selling  Shareholders and each person, if any, who
controls the Company or any Selling  Shareholder  within the meaning of the Act,
against  any  losses,  claims,  damages,  liabilities  or  expenses to which the
Company,  or any such  director,  officer,  Selling  Shareholder  or controlling
person may become subject,  under the Act, the Exchange Act, or other federal or
state statutory law or regulation,  or at common law or otherwise  (including in
settlement of any  litigation,  if such  settlement is effected with the written
consent  of  such  Underwriter),   insofar  as  such  losses,  claims,  damages,
liabilities or expenses (or actions in respect  thereof as  contemplated  below)
arise out of or are based  upon any untrue or alleged  untrue  statement  of any
material  fact  contained  in  the  Registration   Statement,   any  Preliminary
Prospectus, the Prospectus, or any amendment or supplement thereto, or arise out
of or are  based  upon the  omission  or  alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such  untrue  statement  or alleged  untrue  statement  or  omission  or alleged
omission was made in the Registration Statement, any Preliminary Prospectus, the
Prospectus,  or any  amendment or  supplement  thereto,  in reliance upon and in
conformity with the information  furnished to the Company  pursuant to Section 4
hereof; and will reimburse the Company, or any such director,  officer,  Selling
Shareholder  or  controlling  person for any legal and other expense  reasonably
incurred by the Company, or any such director,  officer,  Selling Shareholder or
controlling  person  in  connection  with  investigating,  defending,  settling,
compromising  or paying  any such loss,  claim,  damage,  liability,  expense or
action.  In addition to its other  obligations  under this Section  11(b),  each
Underwriter  severally agrees that, as an interim measure during the pendency of
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 this Section  11(b) which relates to  information  furnished to the
Company pursuant to Section 4 hereof, it will reimburse the Company (and, to the
extent applicable,  each officer,  director,  Selling Shareholder or controlling
person) on a quarterly basis for all reasonable legal or other expenses incurred
in  connection  with   investigating  or  defending  any  such  claim,   action,
investigation,  inquiry or other  proceeding,  notwithstanding  the absence of a
judicial   determination  as  to  the  propriety  and   enforceability   of  the
Underwriters'   obligations  to  reimburse  the  Company  (and,  to  the  extent
applicable,  each officer,  director, Selling Shareholder or controlling person)
for such expenses and the possibility  that such payments might later be held to
have been improper by a court of competent jurisdiction.

                                      -22-



To the extent  that any such  interim  reimbursement  payment is so held to have
been  improper,  the  Company  (and,  to the extent  applicable,  each  officer,
director, Selling Shareholder or controlling person) shall promptly return it to
the Underwriters  together with interest,  compounded  daily,  determined on the
basis of the Prime Rate. Any such interim  reimbursement  payments which are not
made to the Company  within 30 days of a request for  reimbursement,  shall bear
interest  at the  Prime  Rate  from the  date of such  request.  This  indemnity
agreement  will be in  addition  to any  liability  which such  Underwriter  may
otherwise have.

                  (c) Promptly after receipt by an indemnified  party under this
Section of notice of the  commencement  of any action,  such  indemnified  party
will, if a claim in respect thereof is to be made against an indemnifying  party
under this Section, notify the indemnifying party in writing of the commencement
thereof;  but the omission so to notify the indemnifying  party will not relieve
it  from  any  liability  which  it  may  have  to  any  indemnified  party  for
contribution or otherwise than under the indemnity  agreement  contained in this
Section  or to the extent it is not  prejudiced  as a  proximate  result of such
failure.  In case any such action is brought against any  indemnified  party and
such  indemnified  party seeks or intends to seek indemnity from an indemnifying
party,  the  indemnifying  party will be entitled to participate in, and, to the
extent that it may wish, jointly with all other  indemnifying  parties similarly
notified, to assume the defense thereof with counsel reasonably  satisfactory to
such indemnified party; provided,  however, if the defendants in any such action
include  both  the  indemnified  party  and  the  indemnifying   party  and  the
indemnified  party shall have reasonably  concluded that there may be a conflict
between the positions of the  indemnifying  party and the  indemnified  party in
conducting  the defense of any such  action or that there may be legal  defenses
available to it and/or other  indemnified  parties which are  different  from or
additional to those available to the indemnifying  party, the indemnified  party
or parties shall have the right to select separate  counsel to assume such legal
defenses and to otherwise participate in the defense of such action on behalf of
such indemnified party or parties.  Upon receipt of notice from the indemnifying
party to such indemnified party of its election so to assume the defense of such
action and approval by the indemnified party of counsel,  the indemnifying party
will not be liable to such indemnified party under this Section for any legal or
other expenses  subsequently  incurred by such  indemnified  party in connection
with the defense  thereof unless (i) the  indemnified  party shall have employed
such counsel in connection  with the  assumption of legal defenses in accordance
with the proviso to the preceding sentence (it being understood,  however,  that
the  indemnifying  party  shall not be liable for the  expenses of more than one
separate counsel, approved by you in the case of paragraph (a), representing the
indemnified  parties  who are parties to such  action) or (ii) the  indemnifying
party shall not have employed counsel reasonably satisfactory to the indemnified
party to represent the  indemnified  party within a reasonable time after notice
of commencement  of the action,  in each of which cases the fees and expenses of
counsel shall be at the expense of the indemnifying party.

                  (d) If the indemnification  provided for in this Section 11 is
required  by its  terms  but is for  any  reason  held to be  unavailable  to or
otherwise  insufficient to hold harmless an indemnified  party under  paragraphs
(a),  (b) or (c) of this Section 11 in respect of any losses,  claims,  damages,
liabilities or expenses  referred to herein,  then each applicable  indemnifying
party shall contribute to the amount paid or payable by such  indemnified  party
as a result of any losses, claims, damages,  liabilities or expenses referred to
herein (i) in such proportion as is appropriate to reflect the relative benefits
received by the Company,  Affiliated  Selling  Shareholders and the Underwriters
from the  offering of the Common  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  the  Company,   Affiliated   Selling
Shareholders and the Underwriters in connection with the statements or omissions
or inaccuracies in

                                      -23-



the representations and warranties herein which resulted in such losses, claims,
damages,  liabilities  or  expenses,  as well as any  other  relevant  equitable
considerations.  The  respective  relative  benefits  received  by the  Company,
Affiliated  Selling  Shareholders and the Underwriters  shall be deemed to be in
the same  proportion,  in the case of the  Company  and the  Affiliated  Selling
Shareholders  as the  total  price  paid to the  Company  and to the  Affiliated
Selling  Shareholders,  respectively,  for the Common Shares sold by them to the
Underwriters  (net of underwriting  commissions but before deducting  expenses),
and in the case of the Underwriters as the underwriting  commissions received by
them bears to the total of such amounts  paid to the Company and the  Affiliated
Selling   Shareholders   and  received  by  the   Underwriters  as  underwriting
commissions.  The relative fault of the Company, Affiliated Selling Shareholders
and the  Underwriters  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 or the  inaccurate or the
alleged  inaccurate   representation  and/or  warranty  relates  to  information
supplied by the Company, Affiliated Selling Shareholders or 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,  claims,  damages,  liabilities  and expenses
referred  to above shall be deemed to include,  subject to the  limitations  set
forth in  paragraph  (c) of this Section 11, any legal or other fees or expenses
reasonably  incurred by such party in connection with investigating or defending
any action or claim.  The  provisions set forth in paragraph (c) of this Section
11 with respect to notice of  commencement  of any action shall apply if a claim
for contribution is to be made under this paragraph (d); provided, however, that
no  additional  notice  shall be required  with  respect to any action for which
notice has been given under paragraph (c) for purposes of  indemnification.  The
Company,  Affiliated  Selling  Shareholders and the  Underwriters  agree that it
would not be just and equitable if contribution pursuant to this Section 11 were
determined  solely 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 account of the equitable  considerations referred to in this paragraph.
Notwithstanding  the  provisions  of this  Section 11, no  Underwriter  shall be
required  to  contribute  any  amount  in  excess  of the  amount  of the  total
underwriting  commissions  received by such  Underwriter in connection  with the
Common Shares underwritten by it and distributed to the public.  Notwithstanding
the provisions of this Section 11, no Affiliated  Selling  Shareholder  shall be
required  to  contribute  any amount in excess of the  proceeds  received by the
Affiliated  Selling  Shareholder  for the Common Shares sold by such  Affiliated
Selling  Shareholder  to  the  Underwriters.  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  11  are  several  in  proportion  to  their   respective   underwriting
commitments and not joint.

                  (e) It is  agreed  that  any  controversy  arising  out of the
operation of the interim reimbursement  arrangements set forth in Sections 11(a)
and (b), including the amounts of any requested  reimbursement  payments and the
method of determining  such amounts,  shall be settled by arbitration  conducted
under the provisions of the  Constitution and Rules of the Board of Governors of
the New York  Stock  Exchange,  Inc.  or  pursuant  to the  Code of  Arbitration
Procedure of the NASD.  Any such  arbitration  must be commenced by service of a
written  demand for  arbitration  or written  notice of intention to  arbitrate,
therein  electing the  arbitration  tribunal.  In the event the party  demanding
arbitration  does not make such  designation of an arbitration  tribunal in such
demand  or  notice,  then the  party  responding  to said  demand  or  notice is
authorized  to do so. Such an  arbitration  would be limited to the operation of
the interim  reimbursement  provisions  contained in Sections  11(a) and (b) and
would not resolve the ultimate  propriety or enforceability of the obligation to
reimburse expenses which is created by the provisions of such Sections 11(a) and
(b) hereof.

                                      -24-



                  Section 12. DEFAULT OF  UNDERWRITERS.  It shall be a condition
to this Agreement and the obligation of the Company and the Selling Shareholders
to sell and deliver the Common  Shares  hereunder,  and of each  Underwriter  to
purchase the Common Shares in the manner as described  herein,  that,  except as
hereinafter in this paragraph provided,  each of the Underwriters shall purchase
and pay for all the Common  Shares  agreed to be purchased  by such  Underwriter
hereunder upon tender to the  Underwriters of all such shares in accordance with
the terms hereof.  If any Underwriter or  Underwriters  default in your or their
obligations  to purchase  Common Shares  hereunder on either the First or Second
Closing Date and the  aggregate  number of Common  Shares which such  defaulting
Underwriter or  Underwriters  agreed but failed to purchase on such Closing Date
does not exceed 10% of the total number of Common Shares which the  Underwriters
are obligated to purchase on such Closing Date, the nondefaulting entities shall
be obligated severally, in proportion to their respective commitments hereunder,
to purchase the Common Shares which such  defaulting  entities agreed but failed
to purchase on such Closing Date. If any  Underwriter or Underwriters so default
and the  aggregate  number of Common  Shares with  respect to which such default
occurs is more than the above  percentage and  arrangements  satisfactory to you
and the Company for the purchase of such Common  Shares by other persons are not
made within 48 hours after such default,  this Agreement will terminate  without
liability  on the part of any  nondefaulting  Underwriter  or the Company or the
Selling  Shareholders  except for the expenses to be paid by the Company and the
Selling  Shareholders  pursuant  to  Section 7 hereof  and  except to the extent
provided in Section 11 hereof.

                  In the event that Common Shares to which a default relates are
to be purchased by the  nondefaulting  entities or by another  party or parties,
you or the Company shall have the right to postpone the First or Second  Closing
Date, as the case may be, for not more than five business days in order that the
necessary  changes  in the  Registration  Statement,  Prospectus  and any  other
documents,  as well as any other arrangements,  may be effected. As used in this
Agreement,  the  term  "Underwriter"  includes  any  person  substituted  for an
Underwriter under this Section.  Nothing herein will relieve you or a defaulting
Underwriter from liability for its default.

                  Section  13.  EFFECTIVE  DATE.  This  Agreement  shall  become
effective  immediately  as to  Sections 7, 9, 11, 14 and 16 and, as to all other
provisions,  (i) if at the time of execution of this Agreement the  Registration
Statement has not become effective,  at 2:00 P.M., California time, on the first
full business day following the effectiveness of the Registration  Statement, or
(ii) if at the time of execution of this  Agreement the  Registration  Statement
has been declared  effective,  at 2:00 P.M.,  California time, on the first full
business  day  following  the  date of  execution  of this  Agreement;  but this
Agreement  shall  nevertheless  become  effective at such earlier time after the
Registration  Statement  becomes effective as you may determine on and by notice
to the Company or by release of any of the Common Shares for sale to the public.
For the purposes of this  Section 13, the Common  Shares shall be deemed to have
been so released upon the release for publication of any newspaper advertisement
relating  to the  Common  Shares or upon the  release  by you of  telegrams  (i)
advising  Underwriters  that the Common Shares are released for public offering,
or (ii) offering the Common Shares for sale to securities dealers, whichever may
occur first.

         Section 14.  TERMINATION.  Without limiting the right to terminate this
Agreement pursuant to any other provision hereof:

                  (a) This  Agreement may be terminated by the Company by notice
to you and the Selling  Shareholders  or by you by notice to the Company and the
Selling  Shareholders  at any time prior to the time this Agreement shall become
effective as to all its provisions,  and any such  termination  shall be without
liability on the part of the Company or the Selling Shareholders to any

                                      -25-



Underwriter (except for the expenses to be paid or reimbursed by the Company and
the Selling  Shareholders  pursuant to Sections 7 and 9 hereof and except to the
extent  provided in Section 11 hereof) or of any  Underwriter  to the Company or
the Selling Shareholders (except to the extent provided in Section 11 hereof).

                  (b) This  Agreement may also be terminated by you prior to the
First Closing Date by notice to the Company and the Selling  Shareholders (i) if
additional material  governmental  restrictions,  not in force and effect on the
date hereof,  shall have been imposed  upon trading in  securities  generally or
minimum or maximum prices shall have been generally  established on the New York
Stock  Exchange  or on the  American  Stock  Exchange or in the over the counter
market by the NASD, or trading in securities generally shall have been suspended
on either  such  Exchange or in the over the  counter  market by the NASD,  or a
general banking  moratorium shall have been established by federal,  New York or
California  authorities,  (ii) if an outbreak or escalation of major hostilities
or other  national  or  international  calamity  or any  substantial  change  in
political,  financial or economic  conditions  shall have occurred or shall have
accelerated  or escalated  to such an extent,  as, in your  judgment,  to affect
adversely the  marketability  of the Common  Shares,  (iii) if any adverse event
shall have  occurred  or shall  exist which  makes  untrue or  incorrect  in any
material  respect any  statement or  information  contained in the  Registration
Statement or Prospectus or which is not reflected in the Registration  Statement
or Prospectus but should be reflected therein in order to make the statements or
information contained therein not misleading in any material respect, or (iv) if
there shall be any action,  suit or proceeding  pending or threatened,  or there
shall  have  been  any   development   or  prospective   development   involving
particularly  the business or  properties or securities of the Company or any of
its subsidiaries or the transactions  contemplated by this Agreement,  which, in
your judgment,  may materially  and adversely  affect the Company's  business or
earnings and makes it  impractical  or  inadvisable  to offer or sell the Common
Shares.  Any  termination  pursuant  to this  subsection  (b)  shall be  without
liability  on  the  part  of  any  Underwriter  to the  Company  or the  Selling
Shareholders  or on the part of the Company or the Selling  Shareholders  to any
Underwriter (except for expenses to be paid or reimbursed by the Company and the

deliver to the  Underwriters  the Common Shares to be sold and delivered by such
Selling  Shareholders  at the  First  Closing  Date  under  the  terms  of  this

without any liability on the part of any  Underwriter  or, except as provided in
Sections 7, 9 and 11 hereof,  the Company or the Selling  Shareholders,  or (ii)

its or their partners, officers or directors or any

                                      -26-



controlling  person, or the Selling  Shareholders,  as the case may be, and will

case their respective successors,  personal  representatives and assigns, and no
other person will have any right or  obligation  hereunder.  No such  assignment
shall  relieve any party of its  obligations  hereunder.  The term  "successors"
shall not include  any  purchaser  of the Common  Shares as such from any of the
Underwriters merely by reason of such purchase.

                  Section  19.   REPRESENTATION   OF  UNDERWRITERS.   Except  as
otherwise  expressly  provided  herein,  any action  under or in respect of this

                  Section  20.  PARTIAL  UNENFORCEABILITY.   The  invalidity  or
unenforceability of any Section,  paragraph or provision of this Agreement shall

for any reason determined to be invalid or unenforceable,  there shall be deemed
to be made such minor changes (and only such minor  changes) as are necessary to
make it valid and enforceable.

                  Section 21.  APPLICABLE  LAW. This Agreement shall be governed
by and  construed  in  accordance  with  the  internal  laws  (and  not the laws
pertaining to conflicts of laws) of the State of California.

                  Section 22.  GENERAL.  This Agreement  constitutes  the entire
