                     MASTER AGREEMENT AMONG UNDERWRITERS

                                                                   May 13, 1988
MONTGOMERY SECURITIES
600 Montgomery Street
San Francisco, California 94111

Ladies and Gentlemen:

        1.  General.  We understand that from time to time you may act as
Representative or as one of the Representatives of the several underwriters of
offerings of securities of various issuers.  This Agreement shall apply to any
such offering of securities in which we elect to act as an underwriter after
receipt of an invitation from your Syndicate Department which shall identify
the issuer, contain information regarding certain terms of the securities to be
offered and specify the amount of our proposed participation (subject to
increase as provided in the applicable Underwriting Agreement), and the names of
the other Representatives, if any. At or prior to the time of an offering, you
will advise us, to the extent applicable, as to the expected offering date, the
expected closing date, the initial public offering price, the interest or
dividend rate (or the method by which such rate is to be determined), the
conversion price, the underwriting discount, the management fee, the selling
concession and the reallowance, except that if the public offering price of the
securities is to be determined by a formula based upon the market price of
certain securities (such procedure being hereinafter referred to as "Formula
Pricing"), you shall so advise us and shall specify the maximum underwriting
discount, management fee and selling concession.  Such information may be
conveyed by you in one or more communications in the form of letters, wires,
telexes or other written communications or by telephone calls (provided any
such telephone calls are promptly confirmed in writing) (such communications
received by us with respect to an offering are hereinafter collectively
referred to as the "Invitation").  If the Underwriting Agreement (as
hereinafter defined) provides for the granting of an option to purchase
additional securities to cover over-allotments, you will notify us, in the
Invitation, of such option.

        This Agreement, as amended or supplemented by the Invitation, shall
become effective with respect to our participation in an offering of securities
if you have received our oral or written acceptance and you do not subsequently
receive a written communication revoking our acceptance prior to the time and
date specified in the Invitation (our unrevoked acceptance after expiration of
such time and date bing hereinafter referred to as our "Acceptance").  Our
Acceptance will constitute our confirmation that, except as otherwise stated in
such Acceptance, each statement included in the Master Underwriters'
Questionnaire set forth as Exhibit A hereto (or otherwise furnished to us) is
correct.

        The issuer of the securities in any offering of securities made
pursuant to this Agreement is hereinafter referred to as the "Company."  If the
Underwriting Agreement does not provide for an over-allotment option, the
securities to be purchased are hereinafter referred to as the "Securities"; if
the Underwriting Agreement provides for an over-allotment option, the
securities the Underwriters (as hereinafter defined) are initially obligated to
purchase pursuant to the Underwriting Agreement are hereinafter called the
"Firm Securities" and any additional securities which may be purchased upon
exercise of the over-allotment option are hereinafter called the "Additional
Securities," with the Firm Securities and all or any part of the Additional
Securities being hereinafter collectively referred to as the "Securities."  Any
underwriters of Securities under this Agreement, including the Representatives
(as hereinafter defined), are hereinafter collectively referred to as the
"Underwriters."  The term "underwriting obligation," as used in this Agreement
with respect to any Underwriter, shall refer to the amount of Securities,
including any Additional Securities (plus such additional Securities as may be
required by the Underwriting Agreement in the event of a default by one or more
of the Underwriters) which such Underwriter is obligated to purchase pursuant
to the provisions of the Underwriting Agreement.  All references herein to
"you" or to the "Representatives" shall mean Montgomery Securities and the
other firm or firms, if any, which are named as Representatives in the
invitation.  The
   2
Securities to be offered may, but need not, be registered for a delayed or
continuous offering pursuant to Rule 415 under the Securities Act of 1933, as
amended (the "Securities Act"). 

        The following provisions of this Agreement shall apply separately to
each individual offering of Securities. This Agreement may be supplemented or
amended by you by written notice to us and, except for supplements or
amendments set forth in an Invitation relating only to a particular offering of
Securities, any such supplement or amendment to this Agreement shall be
effective with respect to any offering of Securities to which this Agreement
applies after this Agreement is so amended or supplemented. 

        2. Underwriting Agreement; Authority of Representatives. We authorize
you to execute and deliver an underwriting or purchase agreement and any
amendment or supplement thereto and any associated pricing agreement or other
similar agreement (collectively, the "Underwriting Agreement") on our behalf
with the Company and/or any selling securityholder(s) with respect to
Securities in such form as you determine. We will be bound by all terms of the
Underwiting Agreement as executed. We understand that changes may be made in
those who are to be Underwriters and in the amount of Securities to be
purchased by them, but the amount of Securities to be purchased by us in
accordance with the terms of this Agreement and the Underwriting Agreement,
including the amount of Additional Securities, if any, which we may become
obligated to purchase by reason of the exercise of any over-allotment option
provided in the Underwriting Agreement, shall not be changed without our
consent. Without limiting the foregoing, we authorize you to (a) determine all
matters relating to advertising and communications with dealers or others, (b)
extend the time within which the Registration Statement (as hereinafter
defined) may become effective, (c) postpone the closing date or dates for any
offering, and (d) exercise any right of cancellation or termination.

        As Representatives of the Underwriters, you are authorized to take such
action as you deem necessary or advisable to carry out this Agreement, the
Underwriting Agreement, and the purchase, sale and distribution of the
Securities, and to agree to any waiver or modification of any provision of the 
Underwriting Agreement.  To the extent applicable, you are also authorized to
determine (i) the amount of Additional Securities, if any, to be purchased by
the Underwriters pursuant to any over-allotment option, and (ii) with respect
to offerings using Formula Pricing, the initial public offering price and the
price at which the Securities are to be purchased by the Underwriters in
accordance with the Underwriting Agreement. Authority with respect to matters
to be determined by you, or by you and the Company pursuant to the Underwriting
Agreement, shall survive the termination of this Agreement. Your authority
hereunder and under the Underwriting Agreement may be exercised by the
Representatives jointly or by Montgomery Securities acting alone. 

        3. Registration Statement and Prospectus. You will furnish to us, to
the extent made available to you by the Company, copies of the registration
statement, the related prospectus and the amendment(s) thereto (excluding
exhibits but including any documents incorporated by reference therein) filed
with the Securities and Exchange Commission (the "Commission") in respect of
the Securities, and our Acceptance of the Invitation with respect to an
offering of Securities will serve to confirm that we are willing to accept the
responsibility of an Underwriter thereunder and to proceed as therein
contemplated. Such Acceptance will further confirm that the statements made
under the heading "Underwriting" in the proposed final form of prospectus,
insofar as they relate to us, do not contain any untrue statment 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. As hereinafter
mentioned, the "Registration Statement" and the "Prospectus" refer to the
Registration Statement and Prospectus included as a part thereof, in the form
in which the Registration Statement becomes effective (including all
information deemed to be a part thereof pursuant to Rule 430A promulgated under
the Securites Act) and the form in which the Prospectus is filed pursuant to
Rule 424(b) under the Securities Act or, if no such filing is required, the
form in which the Prospectus is in at the time the Registration Statement in
which it is contained becomes effective, with respect to the Securities. Each
preliminary prospectus with respect to the Securities is herein referred to as
a "Preliminary Prospectus." The use of our name in the Prospectus and any
Preliminary Prospectus, as one of the Underwriters, has our consent. You are

                                      2
   3
authorized, with the approval of counsel for the Underwriters, to approve on
our behalf any further amendments or supplements to the Registration Statement
or the Prospectus which may be necessary or appropriate.

        4.  Compensation.  As our share of the compensation to be paid for your
services, we will pay you, and we authorize you to charge our account therefor,
a management fee as specified in the Invitation for the offering. If there is
more than one Representative, such compensation will be divided among the
Representatives in such proportion as you may determine.

        5.  Public Offering.  In connection with the public offering of the
Securities, we authorize you, in your discretion:

            (a) to determine the time of the initial public offering, the
    initial public offering price, the purchase price of the Securities to the
    Underwriters, and the concessions and discounts to Selected Dealers (as
    defined below) to change the public offering price and such concessions and
    discounts (and we agree to be bound by any such change), to furnish the
    Company with the information to be included in the Registration Statement
    and any amendment or supplement thereto with respect to the terms of the
    offering, and to determine all matters relating to advertising and
    communications with Selected Dealers and others;

            (b) to reserve for sale to dealers selected by you, among whom
    any  of the Underwriters may be included ("Selected Dealers"), who shall be
    either (i) members of the National Association of Securities Dealers, Inc.
    (the "Association") who agree in writing to comply with Section 24 of
    Article III of the Association's Rules of Fair Practice or (ii) foreign
    dealers not eligible for membership in the Association who agree in writing
    not to make sales within the United States, its territories or possessions
    or to persons who are citizens or residents therein, to comply with the
    Association's Interpretation with Respect to Free-Riding and Withholding,
    and to comply with Sections 8, 24, 25 (as such Sections apply to foreign
    non-members  of the Association) and 36 of Article III of the Association's
    Rules of Fair Practice, and to others, all or any part of the Securities to
    be purchased by us, such reservations for sales to Selected Dealers to be
    in such proportions as you may determine and such reservations for sales to
    others to be as nearly as practicable in proportion to the respective
    underwriting obligations of the Underwriters unless you agree to a smaller
    proportion at the request of any Underwriter, and from time to time to add
    to the reserved Securities any Securities retained by us remaining unsold
    and to release to us any of our Securities reserved but not sold;

            (c) to sell reserved Securities as nearly as practicable in
    proportion to the respective reservations, (i) to Selected Dealers, under
    Selected Dealers Agreements in substantially the form attached hereto as
    Exhibit B or otherwise, at the public offering price less the applicable
    Selected Dealers' concession, and (ii) to others at the public offering 
    price; and

            (d) to buy Securities for our account from Selected Dealers at the 
    initial public offering price less such amount not in excess of the
    applicable Selected Dealers' concession as you determine.

    After, and only after, advice from you that the Securities are released
for public offering, we will offer to the public in conformity with the terms
of the offering as set forth in the Prospectus or any amendment or supplement
thereto such of the Securities to be purchased by us as you advise us are not
reserved.

    We will comply with any and all restrictions which may be set forth in
the Invitation.  The initial public advertisement with respect to the
Securities shall appeal on such date, and shall include the names of such of
the Underwriters, as you may determine.

    6. Additional Provisions Regarding Sales.  Any Securities sold by us
(otherwise than through you) which you purchase in the open market or otherwise
prior to the termination of this Agreement as provided in Section 12, shall be
repurchased by us on demand at the cost to you of such purchase plus commissions
and taxes on redelivery.  Securities delivered on such repurchase need not be
the  

                                      3
   4
identical Securities so purchased. In lieu of such action, you may, in your
discretion, sell for our account the Securities so purchased and debit or
credit our account for the loss or profit resulting from such sale, or charge
our account with an amount not in excess of the Selected Dealers' concession
with respect to such Securities.

        Sales of Securities among the Underwriters may be made with your prior
consent or as you deem advisable for Blue Sky law purposes. 

        In connection with offers to sell and sales of the Securities, we will
comply with all applicable laws and all applicable rules, regulations and
interpretations of all governmental and self-regulatory agencies.

        7.  Payment and Delivery. At or before such time, on such dates as you
may specify in the Invitation and at your offices unless you otherwise specify
in the Invitation, we will deliver to you a certified or bank cashier's check
in such funds as are specified in the Invitation, payable to the order of
Montgomery Securities (unless otherwise specified in the Invitation) in an
amount equal to, as you direct, either (i) the public offering price or prices
plus accrued interest, amortization of original issue discount or dividends, if
any, set forth in the Prospectus less the concession to Selected Dealers in
respect of the amount of Securities to be purchased by us in accordance with
the terms of this Agreement, or (ii) the amount set forth in the Invitation
with respect to the Securites to be purchased by us. We authorize you to make
payment for our account of the purchase price for the Securities to be
purchased by us against delivery to you of such Securities (which, in the case
of Securities which are debt obligations, may be in temporary form), and the
difference between such purchase price of the Securities and the amount of our
funds delivered to you therefor shall be credited to our account.

        You may, in your discretion, make payment of such purchase price on our
behalf as provided in Section 8 hereof, but any such payment shall not relieve
us of any of our obligations under the Underwriting Agreement or under this
Agreement and we agree to pay you on demand the amount so advanced for our 
account. We authorize you, as our custodian, to take delivery of our Securities 
and to hold the same for our account, in your name or otherwise subject to the
provisions of this Agreement, and to deliver our reserved Securities against
sales. Delivery to us of Securities retained by us for direct sale shall be
made by you as soon as practicable after your receipt of the Securities. Upon
termination of the provisions of this Agreement as provided in Section 12, you
shall deliver to us any Securities reserved for our account for sale to
Selected Dealers and others which remain unsold at that time, except that if,
upon such termination, the aggregate of all reserved and unsold Securities of
all Underwriters does not exceed 10% of the total amount of Securities
underwritten, you are authorized in your discretion to sell such Securities for
the accounts of the several Underwriters at such price or prices as you may
determine. After you receive payment for reserved Securities sold for our
account, you shall remit to us the purchase price paid by us for such
Securities and debit or credit our account with the difference (if any) between
the sale price and such purchase price.

        If we are a member of The Depository Trust Company or any other
depository or similar facility, you are authorized to make appropriate
arrangements for payment for and/or delivery through its facilities of the
Securities to be purchased by us, or, if we are not a member, settlement may be
made through a correspondent that is a member pursuant to our timely
instructions to you.

        In the event that the Underwriting Agreement for an offering provides
for the payment of a commission or other compensation to the Underwriters, we
authorize you to receive such commission or other compensation for our account.

        8.  Authority to Borrow. In connection with the purchase or
carrying for our account of any of the Securities to be purchased by us under
this Agreement or the Underwriting Agreement or any other securities purchased
for our account pursuant to Section 9 hereof, we authorize you, in your
discretion, to advance your funds for our account, charging current interest
rates (but not in excess of the amount permitted by law), to arrange loans for
our account, and in connection therewith to execute and deliver any notes or
other instruments and hold or pledge as security any of our Securities


                                      4
   5
or other securities purchased for our account. Any lender may rely upon your
instructions in all matters relating to any such loan.

        Any Securities held by you for our account may be delivered to us for
carrying purposes, and if so delivered will be redelivered to you upon demand.

        9.  Stabilization and Over-Allotment. We authorize you, in your
discretion, to make purchases and sales of the Securities, any other securities
of the Company of the same class and series, any securities of the Company into 
which the Securities are convertible or exchangeable and any other securities of
the Company which you may designate, in the open market or otherwise, for long
or short account, on such terms and for such prices as you deem advisable, and
to over-allot in arranging sales. Such purchases and sales and over-allotments
will be made for the accounts of the Underwriters as nearly as practicable in
proportion to their respective underwriting obligations. It is understood that
you may have made purchases of securities of the Company for stabilizing
purposes prior to the time when we become one of the Underwriters, and we agree
that any securities so purchased shall be treated as having been purchased for
the respective accounts of the Underwriters pursuant to the foregoing
authorization. We authorize you, in your discretion, to cover any short
position or liquidate any long position incurred pursuant to this Section 9 by 
purchasing or selling Securities on such terms and at such times and prices
during the term of this Agreement or after its termination as you deem
advisable. At no time will the amount of our net commitment either for long or
short account under this Section 9 exceed 15% of our underwriting obligation.
Soley for the purposes of the immediately preceding sentence, our "underwriting
obligation" shall be deemed to exclude any Securities which we are obligated to
purchase solely by virtue of the exercise of an over-allotment option. We will
on demand take up and pay at cost Securities so purchased and deliver any
Securities so sold or overalloted for our account, and, if any Underwriter
defaults in any such obligation, each non-defaulting Underwriter will assume
its proportionate share of such obligation without relieving the defaulting
Underwriter from liability. The provisions of this Section 9 do not constitute
an assurance that the price of the Securities will be stabilized or that
stabilization, if commenced, may not be discontinued at any time.

        Upon request, we will advise you of the Securities retained by us and
unsold and will sell to you for the account of one or more of the Underwriters
such of the unsold Securities retained by us and at such price, not less than
the applicable net price to Selected Dealers nor more than the public offering
price, as you may determine.

        We and each other Underwriter authorize you, as our Representative, to
file with the Securities and Exchange Commssion (the "Commission") any notices
and reports which may be required as a result of any transactions made by you
for the accounts of the Underwriters pursuant to this Section 9. We understand
that, in the event that you effect stabilization pursuant to this Section, you
will notify us promptly of the date and time when the first stabilizing
purchase is effected and the date and time when stabilizing terminated. We
agree that stabilizing by us may be effected only with your consent, and we
will furnish you with such information and reports relating to such
stabilization as are required by the rules and regulations of the Commission
under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

        10.  Open Market Transactions. Until termination of this Agreement,
unless this restriction is sooner terminated by you, we agree not to bid for,
purchase, sell or attempt to induce others to purchase or sell, directly or
indirectly, any of the Securities or securities exchangeable for, or convertible
into, or exercisable against the Securities, any security of the same class and
series as the Securities and any right to purchase the Securities or any such
security, including trading in any put or call option on any such security other
than (a) as provided for in this Agreement or in the Underwriting Agreement or
(b) as a broker in executing unsolicited orders.

        We represent that we have not participated in any transaction
prohibited by the preceding paragraph and that we have at all times complied
with the provisions of Rule 10b-6 of the Commission applicable to the offering
of the Securities.

                                      5

   6
        11.  Expenses and Settlement.  You may charge our account with all
transfer taxes on sales or purchases made of Securities purchased for our
account and with our proportionate share (based upon our underwriting
obligation or upon sales for our accounts, as you shall determine in your sole
discretion) of all other expenses incurred by you under this Agreement or in
connection with the purchase, carrying, sale or distribution of the Securities.
With respect to each offering of Securities to which this Agreement applies,
the respective accounts of the Underwriters shall be settled as promptly as
practicable after the termination of this Agreement as provided in Section 12,
but you may reserve such amount as you deem advisable for additional expenses.
Your determination of the amount to be paid to or by us will be conclusive. You
may at any time make partial distributions of credit balances or call for
payment of debit balances. Any of our funds in your hands may be held with your
general funds without segregation and without accountability for interest.
Notwithstanding any settlement, we will remain liable for taxes on transfers
for our account and for our proportionate share (based upon our underwriting
obligation) of all expenses and liabilities which may be incurred by or for the
accounts of the Underwriters with respect to each offering of Securities to
which this Agreement applies.

        12.  Termination.  With respect to each offering of Securities to which
this Agreement applies, all limitations in this Agreement on the price at which
the Securities may be sold, the periods of time referred to in Sections 6, 7,
11 and 18, the authority granted by the first sentence of Section 9, and the
restrictions contained in Section 10, shall terminate at the close of business
on the 30th day after the commencement of the offering of such Securities. You
may terminate any or all of such provisions at any time prior thereto by notice
to the Underwriters. All other provisions of this Agreement shall survive the
termination of such provisions and shall remain operative and in full force and
effect with respect to such offering.

        13.  Default by Underwriters.  Default by one or more Underwriters
hereunder or under the Underwriting Agreement shall not release the other
Underwriters from their obligations or affect the liability of any defaulting
Underwriter to the other Underwriters for damages resulting from such default.
If one or more Underwriters default under the Underwriting Agreement, you may
(but shall not be obligated to) arrange for the purchase by others, including
you or other non-defaulting Underwriters, of the Securities not taken up by the
defaulting Underwriter or Underwriters.

        In the event that such arrangements are made, the respective
underwriting obligations of the non-defaulting Underwriters and the amounts of
the Securities to be purchased by others, if any, shall be taken as the basis
for all rights and obligations hereunder; but this shall not in any way affect
the liability of any defaulting Underwriter to the other Underwriters for
damages resulting from its default, nor shall any such default relieve any
other Underwriter of any of its obligations hereunder or under the Underwriting
Agreement except as herein or therein provided. In addition, in the event of
default by one or more Underwriters in respect of their obligations under the
Underwriting Agreement to purchase the Securities agreed to be purchased by
them thereunder and, to the extent that arrangements shall not have been made
by you for any person to assume the obligations of such defaulting Underwriter
or Underwriters, we agree, if provided in the Underwriting Agreement, to assume
our proportionate share, based upon our underwriting obligation, of the
obligations of each such defaulting Underwriter (subject to the limitations
contained in the Underwriting Agreement) without relieving such defaulting
Underwriter of its liability therefor.

        In the event of default by one or more Underwriters in respect of their
obligations under this Agreement to take up and pay for any shares of
Securities purchased by you for their respective accounts pursuant to Section 9
hereof, or to deliver any such shares of Securities sold or over-allotted by
you for their respective accounts pursuant to any provision of this Agreement,
and to the extent that arrangements shall not have been made by you for other
persons to assume the obligations of such defaulting Underwriter or
Underwriters, each non-defaulting Underwriter shall assume its proportionate
share of the aforesaid obligations of each such defaulting Underwriter without
relieving any such defaulting Underwriter of its liability therefor.

     14.  Position of Representatives; No Liability for Certain Matters.  You
shall be under no liability to us for any act or omission except for your lack
of good faith in the performance of the obligations expressly assumed by you in
this Agreement, but no obligations on your part shall be implied or inferred
herefrom.  Without limitation, you shall be under no liability for or in
respect of the validity or value of, or title to, the Securities; the form of,
or the statements contained in, or the validity of, the Registration Statement
as initially filed, any Preliminary Prospectus, the Registration Statement or
the Prospectus, or any amendment or supplement to any of them, or any other
letters or instruments executed by or on behalf of the Company or others; the
form or validity of the Underwriting Agreement, the Selected Dealers Agreement
or this Agreement; the delivery of the Securities; the performance by the
Company or others of any agreement on its or their part to be performed; the
qualification of the Securities for sale under the laws of any jurisdiction; or
any matter in connection with any of the foregoing.  The rights and liabilities
of the Underwriters are several and not joint and nothing shall constitute the
Underwriters a partnership, association or separate entity.

     If the Underwriters are deemed to constitute a partnership for federal
income tax purposes, we elect to be excluded from the application of Subchapter
K, Chapter 1, Subtitle A, of the Internal Revenue Code of 1986, as amended,
and agree not to take any position inconsistent with such election, and you are
authorized, in your discretion, to execute on behalf of the Underwriters such
evidence of such election as may be required by the Internal Revenue Service.

     15.  Indemnification.  We will indemnify and hold harmless each other
Underwriter and each person, if any, who controls such Underwriter within the
meaning of Section 15 of the Securities Act, to the extent and upon the terms
upon which each Underwriter agrees to indemnify the Company and other specified
persons as set forth in the Underwriting Agreement.

     If at any time claim or claims (whether alone or together with another
claim or claims) shall be asserted against you, individually or as
Representative of the Underwriters, or against any other Underwriter, or
against any person who controls either you or such other Underwriter within the
meaning of Section 15 of the Securities Act, which claim or claims arise out of
or are based in whole or in part upon (i) any actual or alleged untrue or
misleading statement in or omission from any version of the Registration
Statement or Prospectus, or any amendment or supplement to any of them, (ii)
any actual or alleged action or omission to act by you or any other
Underwriter or any other person in connection with the preparation for and
management or other effectuation of any of the transactions contemplated by
this Agreement, the Selected Dealers Agreement or the Underwriting Agreement or
(iii) any other actual or alleged action or omission in connection with or
related to the offer or sale of the Securities, we authorize you to make such
investigation, to retain or arrange for or approve the retaining of such
attorneys (including, in your discretion, separate attorneys for any single
Underwriter or group of Underwriters) and to take such other action as you
shall deem necessary or desirable under the circumstances, including settlement
of any such claim or claims.  We will pay you, on request, our proportionate
share (based upon the underwriting obligation of all Underwwriters
participating in such indemnification) of all expenses incurred by you to the
date of each such request (including, without limitation, cost of investigation
and the fees and disbursements of your attorneys and any other attorneys
retained by you or whose retaining you arrange for or approve) in
investigating, defending against and negotiating with respect to such claim or
claims, and our similar proportionate share of any liability incurred to the
date of each such request by you, by any such other Underwriter or by any such
controlling person in respect of such claim or claims, whether such liability
shall be the result of a judgment or the result of any such settlement.  In
determining the amount of our obligation under this paragraph, appropriate
adjustment may be made by you to reflect any amounts received by any one or
more Underwriters in respect of such claim from the Company pursuant to the
Underwriting Agreement or otherwise.  If any Underwriter or Underwriters
default in their obligation to make any payments under this second paragraph of
Section 15, each non-defaulting Underwriter shall be obligated to pay its
proportionate share of all defaulted payments, based upon such Underwriter's
underwriting obligation as related to the underwriting obligations of all
non-defaulting Underwriters.  Nothing herein shall relieve a defaulting
Underwriter from liability for its

                                      7
   8
default.  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.

        In addition and without limitation, we will indemnify and hold harmless
you, each other Underwriter and each person, if any, who controls you and each
Underwriter within the meaning of Section 15 of the Securities Act, against any
claim or claims, liabilities and expenses (including, without limitation, costs
of investigation, attorneys' fees and disbursements and amounts paid upon
judgment or settlement) to which you, any such other Underwriters and any such
controlling persons may become subject or incur, in whole or in part, as a
result of our actual or alleged failure to timely perform our obligations under
this Agreement, the Underwriting Agreement or under applicable law or the
inaccuracy of any of our representations in this Agreement or the Master
Underwriters' Questionnaire (as attached hereto as Exhibit A), and we will,
upon such request as may be made from time to time, pay to you, each such other
Underwriter and each such controlling person (i) such expenses as have been
incurred by you, such other Underwriters and such controlling persons to the
date of each such request (including, without limitation, costs of
investigation and attorneys' fees and disbursements) in whole or in part in
investigating, defending against and negotiating with respect to such claim or
claims, and (ii) any liabilities incurred by you, such other Underwriters or
such controlling persons to the date of each such request, in whole or in part,
as a result of such claim or claims, whether such liability shall be the result
of a judgment or the result of any settlement made by you, such other
Underwriter or such controlling person.

        You shall give us reasonably prompt notice of the assertion of any such
claim or claims referred to in this Section 15, as well as such reports from
time to time as you shall deem reasonable as to the status thereof and as to
the actions taken by you in respect thereof pursuant to the foregoing
authorizations and indemnifications, although your failure to do so shall not
affect our obligations hereunder.  In addition, we will cooperate with you and
attorneys retained by you (or which you arranged for or approved the retaining
of) in investigating and defending against any such claim or claims referred to
in this Section 15 and will make available all relevant records and documents
and appropriate personnel.  We understand that the discharge of any obligations
that we may have under the provisions of the preceding two paragraphs of this
Section 15 shall not relieve us of any obligation that we may have under the
first paragraph of this Section 15.  The foregoing indemnifications will be in
addition to, and will not supersede, any other indemnification to which you,
any such other Underwriter and any such controlling person shall be entitled 
from us by virtue of this Agreement, by operation of law or otherwise.

        The provisions of Section 14 hereof and our agreements contained in
this Section 15 shall remain in full force and effect regardless of any
investigation made by or on behalf of you, any other Underwriter or any
controlling person and shall survive the delivery of the Securities and the
termination of this Agreement and the similar agreements entered into with the
other Underwriters.

        16.  Reports and Blue Sky Matters.  We authorize you to file with the
Commission and any other governmental agency any reports required in connection
with any transactions effected by you for our account pursuant to this
Agreement and the Underwriting Agreement, and we will furnish any information
needed for such reports.  As provided in Section 9 hereof, we agree to notify
you in writing of the information specified in Rule 17a-2(d) of the Commission
promulgated under the Exchange Act.  You shall not have any responsibility with
repect to the right of any Underwriter or other person to sell the Securities
in any jurisdiction, notwithstanding any information you may furnish in that
connection.

        We are familiar with Rule 15c2-8 promulgated under the Exchange Act
relating to the distribution of preliminary and final prospectuses for
securities of an issuer (whether or not the issuer is subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act) and confirm that we
will comply therewith in connection with any sale of Securities.

attached as Exhibit A hereto (which information has been furnished to the
Company for use in the Registration Statement or the Prospectus) is correct.

exercise discretionary authority.
