Dear Sirs:

                 SECTION 1.  Introductory.  Atrix Laboraties, Inc., a Delaware
corporation (the "Company"), proposes to issue and sell 2,500,000 shares of its
authorized but unissued Common Stock (the "Common Stock") to you (the
"Underwriters").  Said aggregate of 2,500,000 shares are herein called the
"Firm Common Shares."  In addition, the Company proposes to grant to the
Underwriters an option to purchase up to 375,000 additional shares of Common
Stock (the "Optional Common Shares"), as provided in Section 4 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 that the Underwriters propose to
make a public offering of their 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 hereby confirms its 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:




                                      1

                 (a)  A registration statement on Form S-3 (File No. 333-___)
         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 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
         amendments, 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
         for each of the Underwriters.  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, (ii) a final prospectus in accordance with
         Rules 430A and 424(b) of the Rules and Regulations or (iii) a term
         sheet (the "Term Sheet") as described in and in accordance with Rules
         434 and 424(b) of the Rules and Regulations.  As filed, the final
         prospectus, if one is used, or the Term Sheet and Preliminary
         Prospectus, if a final prospectus is not used, shall include all Rule
         430A Information 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) any
         registration statement filed pursuant to 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 either (i) 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, (ii) if a
         Term Sheet is not used and 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 or (iii) if a Term Sheet is
         used, the Term Sheet in the form in which it is first filed with the
         Commission pursuant to Rule 424(b) of the Rules and Regulations,
         together with the Preliminary Prospectus included in the Registration





                                      2
   3
         Statement at the time it 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 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 any Underwriter 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, and the rules and regulations of the Commission 
         thereunder (the "Exchange Act"), 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, including
         any subsidiary.  The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of its
         jurisdiction of incorporation, with full power and authority
         (corporate and other) to own and lease its properties and conduct its
         respective business as described in the Prospectus; the Company is in
         possession of and operating in compliance with all authorizations,
         licenses, permits, consents, certificates and orders material to the
         conduct of its business, all of which are valid and in full force and
         effect; the Company is duly qualified to do business and is in good
         standing as a foreign corporation in each jurisdiction in which the
         ownership or leasing of properties or the conduct of its business
         requires such qualification, except for jurisdictions in which the
         failure to so qualify would not have a material adverse effect upon
         the Company; and no proceeding has been instituted in any




                                      3
   4
         such jurisdiction, revoking, limiting or curtailing, or seeking to
         revoke, limit or curtail, such power and authority or qualification.

                 (d)  The Company has an authorized and outstanding capital
         stock as set forth under the heading "Capitalization" in the
         Prospectus; the issued and outstanding shares of Common Stock have
         been duly authorized and validly issued, are fully paid and
         nonassessable, are duly listed on the Nasdaq National 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.  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, the Company has no outstanding 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 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 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 stockholder of the Company has any right which has not
         been waived to require the Company to register the sale of any shares
         owned by such stockholder under the Act in the public offering
         contemplated by this Agreement.  No further approval or authority of
         the stockholders or the Board of Directors of the Company will be
         required for 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 (i) violate any
         provisions of the certificate of incorporation or bylaws, or other
         organizational documents, of the Company, or (ii) 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 is a party
         or by which the Company or any of its respective properties may be
         bound or affected,





                                      4
   5
         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
         respective properties, which conflict, breach, violation or default
         referred to in this clause (ii) is material.  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)  Deloitte & Touche, LLP, who have expressed their opinion
         with respect to the financial statements and schedules filed with the
         Commission as a part of the Registration Statement and included 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 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 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 data set forth in the Prospectus
         under the captions "Capitalization" and "Selected 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, the Company is not in violation or default of any
         provision of its certificate of incorporation or bylaws, or other
         organizational documents, nor 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 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 accurate and complete; all such
         contracts are in full force and effect on the date hereof (other than
         any such contracts that have expired in accordance with their terms); 
         and neither the Company, nor to the best of the Company's knowledge, 
         any other party is in breach of or default under any of such contracts.

   6
                 (k)  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 is or may be a party or of which
         property owned or leased by the Company is or may be the subject, or
         related to environmental or discrimination matters, which actions,
         suits or proceedings might, 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 no labor disturbance by the employees of the
         Company exists or is imminent which might be expected to affect
         adversely such condition, properties, business, results of operations
         or prospects.  The Company is not 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 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.  The Company 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.
         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 has 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 could result in a material reduction in
         the future earnings of the Company; (ii) the Company has not sustained
         any material loss or interference with its business 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 capital stock and
         the Company is 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 described in the
         Registration Statement) or indebtedness material to the Company (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.

                 (n)  Except as disclosed in or specifically contemplated by
         the Prospectus, the Company has sufficient trademarks, trade names,
         patent rights, mask works, copyrights, licenses, approvals and
         governmental authorizations to conduct its business as now conducted;
         the expiration of any trademarks, trade names, patent rights, mask
         works, copyrights, licenses, approvals or governmental authorizations
         would not have a material





                                      6
   7
         adverse effect on the condition (financial or otherwise), business,
         results of operations or prospects of the Company; and the Company has
         no knowledge of any material infringement by it of trademark, trade
         name rights, patent rights, mask works, copyrights, licenses, trade
         secret or other similar rights of others, and there is no claim being
         made against the Company regarding trademark, trade name, patent, mask
         work, copyright, license, trade secret or other infringement which
         could have a material adverse effect on the condition (financial or
         otherwise), business, results of operations or prospects of the
         Company.

                 (o)  The Company has not been advised, and has no reason to
         believe, that it 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.

                 (p)  The Company has filed all necessary federal, state and
         foreign income and franchise tax returns and has paid 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
         which could materially and adversely affect the business, operations
         or properties of the Company.

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

                 (t)  The Company has not at any time during the last five
         years (i) made any unlawful contribution to any candidate for foreign
         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 that might be reasonably
         expected to cause or result in stabilization or





                                      7
   8
         manipulation of the price of the Common Stock to facilitate the sale 
         or resale of the Common Shares.

         SECTION 3.  Representations and Warranties of the Underwriters.  The
several Underwriters, represent and warrant to the Company 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 and (ii) 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.

SECTION 4.  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, the Company agrees to issue and sell to
the Underwriters the Firm Common Shares.  The Underwriters agree, severally and
not jointly, to purchase from the Company the number of Firm Common Shares
described below.  The purchase price per share to be paid by the several
Underwriters to the Company shall be equal to the initial price to the public
per share less an amount per share equal to the per share underwriting
discount.  The initial price to the public, which shall be a fixed price, and
the underwriting discount will be determined by separate agreement between the
Company and the Underwriters in substantially the form set forth as Schedule B
hereto on the basis of the reported prices or quotations of the Common Stock on
the National Association of Securities Dealers, Inc. Automated Quotation System
(NASDAQ) immediately prior to the determination.  Such initial public offering
price shall not be higher than the last sale price of the Common Stock of the
Company in the National Market System as reported by NASDAQ immediately prior
to such determination of the initial public offering price.

The obligation of each Underwriter to the Company shall be to purchase from the
Company that number of full shares set forth opposite the name of such
Underwriter in Schedule A hereto.

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 the Underwriters) 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) under 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 at 
such other time and date, not later than one week after such fifth full 
business day as may be agreed upon by the Company and the Underwriters) (the 
"First Closing Date"); provided, however, that if the Prospectus is at any 
time prior to the First Closing Date recirculated to the public, the First 
Closing Date shall occur upon the later of the third or fourth, as the case 
may be, full business day following the first date that any of the Common 
Shares are released by you for sale to the public or the date that is 48 hours 
after the date that the Prospectus has been so recirculated.

Delivery of certificates for the Firm Common Shares shall be made by or on
behalf of the Company to you, for the respective accounts of the Underwriters
against payment by you, for the accounts of the several Underwriters, of the
purchase price therefor by fed funds to the order of





                                      8
   9
the Company.  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.  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
Company hereby grants an option to the several Underwriters to purchase,
severally and not jointly, up to an aggregate of 375,000 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 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," shall be determined by you, but if at any time other than the
First Closing Date shall not be earlier than three nor later than five 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 Company
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 2,500,000
(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 Company 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 Company.  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.

You have advised the Company that each Underwriter has authorized you to accept
delivery of its Common Shares, to make payment and to receipt therefor.  You
may (but shall not be obligated to) make payment for any Common Shares to be
purchased by any Underwriter whose funds shall not have been received by you by
the First Closing Date or the Second Closing Date, as the case may be, for the
account of such Underwriter, but any such payment shall not relieve such
Underwriter from any of its obligations under this Agreement.

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 the judgment of the
Underwriters is advisable and at the public





                                      9
   10
offering price set forth on the cover page of and on the terms set forth in the
final prospectus, if one is used, or on the first page of the Term Sheet, if
one is used.

         SECTION 5.  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
         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 several 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





                                     10
   11
         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) covering a period of 12 consecutive months beginning
         after the effective date of the Registration Statement 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 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 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 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 each of the Underwriters:  (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, stockholders' 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.

   12
                 (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 Montgomery Securities (which
         consent may be withheld at the sole discretion of Montgomery 
         Securities) the Company will not other than pursuant to stock option 
         plans disclosed in the Prospectus and any options granted thereunder 
         issue, offer, sell, grant options to purchase or otherwise dispose of 
         any of the Company's equity securities or any other securities 
         convertible into or exchangeable with 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),
         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.

                 (k)  The Company will use its best efforts to list, subject to
         official notice of issuance, on the Nasdaq National Market, the Stock
         to be issued and sold by the Company.

                 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 6.  Payment of Expenses.  Whether or not the transactions
contemplated hereunder are consummated or this Agreement becomes effective or
is terminated, the Company agrees to pay all costs, fees and expenses incurred
in connection with the performance of its obligations hereunder and in
connection with the transactions contemplated hereby, including without
limiting the generality of the foregoing, (i) all expenses incident to the

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.
Except as provided in this Section 6, Section 8 and Section 10 hereof, the





                                     12
   13
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 Blue Sky laws and the Blue Sky memorandum

         SECTION 7.  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

provisions hereof, to the performance by the Company of its obligations
hereunder, and to the following additional conditions:

         filed pursuant to Rule 462(b) of the Rules and Regulations relating to
         the Common Shares, not later than 10 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 or you, shall be
         contemplated by the Commission; and any request of the Commission for
         inclusion of 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

         Date, in form and substance satisfactory to you, except as otherwise
         expressly provided below:

                          (i)  An opinion of Kutak Rock, counsel for the
                 Company, addressed to the Underwriters and dated the First
                 Closing Date, or the Second Closing Date, as the case may be,
                 to the effect that:

                                  (1)  The Company has been duly incorporated
                          and is validly existing as a corporation in good

                          foreign corporation and is in good standing in all
                          other jurisdictions where the ownership or leasing of
                          properties or the conduct of its business requires
                          such qualification, except for jurisdictions in which
                          the failure to so qualify would not have a material
                          adverse effect on the Company, and has full corporate
                          power and authority to own its properties and conduct
                          its business as described in the Registration
                          Statement;

                                  (2)  The authorized, issued and outstanding
                          capital stock of the Company is as set forth under
                          the caption "Capitalization" in the Prospectus; all
                          necessary and proper corporate proceedings have been
                          taken in order to authorize validly such authorized
                          capital stock; all outstanding shares of Common Stock
                          have been duly and validly issued, are fully paid 
                          and nonassessable, have been issued in compliance 
                          with 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 
                          any securities and conform to the description

         supplement, contains any untrue statement of a material fact or omits

                 the matters described therein.  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 as of the date of this Agreement or as of
                 the First Closing Date or the Second Closing Date, as the case

                 paragraph only), and "Business - Government Regulation" and 
                 to the extent they reflect matters arising under the federal 
                 Food, Drug and Cosmetic Act, the regulations thereto or legal
                 conclusions relating to such law such statements fairly

                 case may be, such section of the Registration Statement and 
                 the Prospectus, or any amendment or supplement, contained any

                 material fact necessary to make the statements therein not 
                 misleading;

                 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.

                          (v)  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





                                     18
   19
                          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; in his opinion and to
                          the best of his knowledge, the Registration Statement
                          and the Prospectus and any amendments or supplements
                          thereto contain all statements required to be stated
                          therein regarding the Company; 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 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
                          involving a material adverse change in the condition
                          (financial or otherwise), business, properties,
                          results of operations, management or prospects of the
                          Company; and no legal or governmental action, suit or
                          proceeding is pending or threatened against the
                          Company which is material to the Company, 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, the Company
                          has not entered into any verbal or written agreement
                          or other transaction which is not in the ordinary
                          course of business or which could 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, 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 stockholders 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





                                     19
   20
                          contemplated by the Prospectus, the Company has not
                          sustained a material loss or damage by strike, fire,
                          flood, windstorm, accident or other calamity (whether
                          or not insured).

                          (vi)  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 Deloitte & Touche, 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.

                          (vii)  On or before the First Closing Date, letters
                 from each director and designated 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 Montgomery Securities, which consent may be 
                 withheld at the sole discretion of Montgomery Securities.

All such opinions, certificates, letters and documents shall be in compliance
with the provisions hereof only if they are satisfactory to you and to Morrison
& Foerster, LLP, 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 the Underwriters 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 without
liability on the part of any Underwriter or the Company except for the expenses
to be paid or reimbursed by the Company pursuant to Sections 6 and 8 hereof and
except to the extent provided in Section 10 hereof.

         SECTION 8.  Reimbursement of Underwriters' Expenses.  Notwithstanding
any other provisions hereof, if this Agreement shall be terminated by you
pursuant to Section 7, 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 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 6 and Section 10 shall at all times be effective and shall
apply.





                                     20
   21
         SECTION 9.  Effectiveness of Registration Statement.  You and the
Company will use your and its 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 10.  Indemnification.

                 (a) The Company agrees 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 contained herein or any failure of the 
         Company to perform its obligations hereunder or under law; and will 
         reimburse each Underwriter and each such controlling person for any 
         legal and other expenses as such expenses are 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 the Company will not 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 3 hereof.  In addition 
         to its other obligations under this Section 10(a), the Company 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, 
         or any inaccuracy in the representations and warranties of the 
         Company herein or failure to perform its obligations hereunder, all 
         as described in this Section 10(a), it 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 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





                                     21
   22
         rate for borrowers of the highest credit standing) announced from time
         to time by Bank of America NT&SA, 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 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 and each person, if any, who
         controls the Company within the meaning of the Act, against any
         losses, claims, damages, liabilities or expenses to which the Company,
         or any such director, officer 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 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, 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 3 hereof; and will reimburse the Company, or any 
         such director, officer or controlling person for any legal and other 
         expenses as such expenses are reasonably incurred by the Company, or 
         any such director, officer 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 10(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 10(b) which relates 
         to information furnished to the Company pursuant to Section 3 hereof, 
         it will reimburse the Company (and, to the extent applicable, each 
         officer, director 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' obligation to reimburse the Company (and, to the extent 
         applicable, each officer, director 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.  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 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





                                     22
   23
         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 next preceding sentence 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 10 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) 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 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 and the Underwriters in connection
         with the statements or omissions





                                     23
   24
         or inaccuracies in 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 and the Underwriters shall
         be deemed to be in the same proportion, in the case of the Company as
         the total price paid to the Company for the Common Shares sold by it
         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 received by the Underwriters as
         underwriting commissions.  The relative fault of the Company 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 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 subparagraph (c) of
         this Section 10, 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 subparagraph (c) of
         this Section 10 with respect to notice of commencement of any action
         shall apply if a claim for contribution is to be made under this
         subparagraph (d); provided, however, that no additional notice shall
         be required with respect to any action for which notice has been given
         under subparagraph (c) for purposes of indemnification.  The Company
         and the Underwriters agree that it would not be just and equitable if
         contribution pursuant to this Section 10 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 the
         immediately preceding paragraph.  Notwithstanding the provisions of
         this Section 10 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.  No person guilty of
         fraudulent misrepresentation (within the meaning of Section 11(f) of
         the Act) shall be entitled to contribution from any person who was not
         guilty of such fraudulent misrepresentation.  The Underwriters'
         obligations to contribute pursuant to this Section 10 are several in
         proportion to their respective underwriting commitments and not joint.

                 (e)  It is agreed that any controversy arising out of the
         operation of the interim reimbursement arrangements set forth in
         Sections 10(a) and 10(b) hereof, 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





                                     24
   25
         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 10(a) and 10(b) hereof and would not resolve the ultimate
         propriety or enforceability of the obligation to reimburse expenses
         which is created by the provisions of such Sections 10(a) and 10(b)
         hereof.

     SECTION 11.  Default of Underwriters.  It shall be a condition to this
Agreement and the obligation of the Company 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 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 non-defaulting Underwriters shall be obligated
severally, in proportion to their respective commitments hereunder, to purchase
the Common Shares which such defaulting Underwriters 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 the
Underwriters 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 non-defaulting Underwriter or
the Company except for the expenses to be paid by the Company pursuant to
Section 6 hereof and except to the extent provided in Section 10 hereof.

     In the event that Common Shares to which a default relates are to be
purchased by the non-defaulting Underwriters or by another party or parties,
the Underwriters 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
a defaulting Underwriter from liability for its default.

     SECTION 12.  Effective Date.  This Agreement shall become effective
immediately as to Sections 6, 8, 10, 13 and 14 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 12, 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





                                     25
   26
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 13.  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 or by you by notice to the Company 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 to any
    Underwriter (except for the expenses to be paid or reimbursed by the
    Company pursuant to Sections 6 and 8 hereof and except to the extent
    provided in Section 10 hereof) or of any Underwriter to the Company (except
    to the extent provided in Section 10 hereof).

            (b)  This Agreement may also be terminated by you prior to the
    First Closing Date by notice to the Company (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 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 the
    judgment of the Underwriters, 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 the reasonable judgment of the Underwriters, may materially and
    adversely affect the Company's business or earnings and makes it
    impracticable or inadvisable to offer or sell the Common Shares.  Any
    termination pursuant to this subsection (b) shall without liability on the
    part of any Underwriter to the Company or on the part of the Company to any
    Underwriter (except for expenses to be paid or reimbursed by the Company
    pursuant to Sections 6 and 8 hereof and except to the extent provided in
    Section 10 hereof.

            (c)  This Agreement shall also terminate at 5:00 P.M., California
    time, on the tenth full business day after the Registration Statement shall
    have become effective if the initial public offering price of the Common
    Shares shall not then as yet have been determined as provided in Section 4
    hereof.  Any termination pursuant to this subsection (c) shall without
    liability on the part of any Underwriter to the Company or on the part of
    the Company to any





                                     26
   27
    Underwriter (except for expenses to be paid or reimbursed by the Company
    pursuant to Sections 6 and 8 hereof and except to the extent provided in
    Section 10 hereof.

     SECTION 14.  Representations and Indemnities to Survive Delivery.  The
respective indemnities, agreements, representations, warranties and other
statements of the Company, of its officers and of the several Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter
or the Company or any of its or their partners, officers or directors or any
controlling person, as the case may be, and will survive delivery of and
payment for the Common Shares sold hereunder and any termination of this
Agreement.

     SECTION 15.  Notices.  All communications hereunder shall be in writing
and, if sent to the Underwriters shall be mailed, delivered or telegraphed and
confirmed to you at Montgomery Securities, 600 Montgomery Street, San
Francisco, California 94111, Attention:  _______________, with a copy to

Attention: Warren L. Troupe, Esq.  The Company or you may change the address 
for receipt of communications hereunder by giving notice to the others.

     SECTION 16.  Successors.  This Agreement will inure to the benefit of and
be binding upon the parties hereto, including any substitute Underwriters
pursuant to Section 11 hereof, and to the benefit of the officers and directors
and controlling persons referred to in Section 10, and in each 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 17.  Partial Unenforceability.  The invalidity or unenforceability
of any Section, paragraph or provision of this Agreement shall not affect the
validity or enforceability of any other Section, paragraph or provision hereof.
If any Section, paragraph or provision of this Agreement is 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 18.  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 19.  General.  This Agreement constitutes the entire agreement of
the parties to this Agreement and supersedes all prior written or oral and all
contemporaneous oral agreements, understandings and negotiations with respect
to the subject matter hereof.  This Agreement may be executed in several
counterparts, each one of which shall be an original, and all of which shall
