MERRILL LYNCH & CO.
Merrill Lynch, Pierce, Fenner & Smith
         Incorporated
North Tower
World Financial Center
New York, New York  10281-1209



Ladies and Gentlemen:

     Capstead Mortgage Corporation, a Maryland corporation (the "Company"),
confirms its agreement with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner &
Smith Incorporated (the "Agent"), with respect to the issue and sale by the
Company of its securities as follows:

     SECTION 1.  Description of Securities.  The Company proposes to issue and
                 -------------------------                                    
sell through the Agent, as non-exclusive sales agent, up to 5,000,000 shares
(the "Common Stock Maximum Amount") of common stock, par value $0.01 per share
(the "Common Stock") and 2,000,000 shares (the "Preferred Stock Maximum Amount"
and, together with the Common Stock Maximum Amount, the "Maximum Amount") of
$1.26 Cumulative Convertible Preferred Stock, Series B, par value $0.10 per
share (the "Preferred Stock" and together with the Common Stock, the "Stock"),
on the terms set forth in Section 2 hereof.  [The Maximum Amount may be changed
from time to time by mutual agreement of the parties hereto.]

     SECTION 2.  Sale and Delivery of Securities.  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
through the Agent, as non-exclusive sales agent, and the Agent agrees to sell,
as non-exclusive sales agent for the Company, on a reasonable efforts basis, up
to the Common Stock Maximum Amount and the Preferred Stock Maximum Amount on the
terms set forth herein. The Stock, up to the Maximum Amount, is to be sold on a
daily basis or otherwise as shall be agreed to by the Company and the Agent.
The

 
Company will designate the maximum number of shares of Common Stock and
Preferred Stock to be sold by the Agent daily (collectively, the Common Stock
and Preferred Stock so designated are referred to herein as the "Shares").
Subject to the terms and conditions hereof, the Agent shall use its reasonable
efforts to sell all of the designated Shares up to the Maximum Amount.

     Notwithstanding the foregoing the Company may instruct the Agent by
telephone (confirmed promptly by telecopy) not to sell Shares if such sales
cannot be effected at or above the price designated by the Company in any such
instruction.  In addition, the Company or the Agent may, upon notice to the
other party hereto by telephone (confirmed promptly by telecopy), suspend the
offering of the Shares; provided, however, that such suspension or termination
                        --------  -------                                     
shall not affect or impair the parties' respective obligations with respect to
the Shares sold hereunder prior to the giving of such notice.

     If either party has reason to believe that the exemptive provisions set
forth in Rule 101(c)(1) of Regulation M under the Securities Exchange Act of
1934 (the "Exchange Act"), are not satisfied with respect to either the Common
Stock or the Preferred Stock, the number of Shares of Common Stock and Preferred
Stock, respectively, that may be sold on any day shall not exceed 10% of the
average daily trading volume of the Common Stock or Preferred Stock, as the case
may be, for the sixty days prior to such day.  Unless otherwise agreed by the
Company and the Agent, the Agent shall sell the Shares only by means of ordinary
brokers' transactions on the New York Stock Exchange (the "NYSE").  Unless
otherwise agreed to by the Company and the Agent, the Agent shall not solicit or
arrange for the solicitation of customer's orders in anticipation of or in
connection with such transactions, nor shall it sell short as principal shares
of Stock of the Company, except in connection with customary market making
activities in the Company's outstanding securities.  The Agent shall not engage
in any special selling efforts or selling methods relating to the Shares within
the meaning of Rule 100 of Regulation M under the Exchange Act.  The Agent shall
calculate on a weekly basis the average daily trading volume of each of the
Common Stock and Preferred Stock.

     The compensation to the Agent for sales of Shares shall be __% of the gross
sales price of the Shares sold, in the form of a commission.  The remaining
proceeds, after further deduction for any transaction fees imposed by any
governmental or self-regulatory organization in respect of such sales, shall
constitute the net proceeds to the Company for such Shares (the "Net Proceeds").

     The Agent shall provide written confirmation to the Company following the
close of trading on the NYSE each day setting forth the number of shares of
Common Stock and Preferred Stock, respectively, sold on such day, the Net
Proceeds to the Company, and the compensation payable by the Company to the
Agent with respect to such sales.

     Settlement for sales of Shares will occur on the third business day
following the date on which such sales are made (each such day, a "Settlement
Date").  On each Settlement Date, the Shares sold through the Agent for
settlement on such date shall be delivered by the

                                       2

 
Company to the Agent against payment of the Net Proceeds for the sale of such
Shares.  Settlement for all Shares shall be effected by free delivery of Shares
to the Agent's account at The Depository Trust Corporation in return for
payments in same day funds delivered to the account designated by the Company.
If the Company shall default on its obligation to deliver Shares on any
Settlement Date, the Company shall (i) hold the Agent harmless against any loss,
claim or damage arising from or as a result of such default by the Company and
(ii) pay the Agent any commission to which it would otherwise be entitled absent
such default.  If the Agent breaches this Agreement by failing to deliver
proceeds on any Settlement Date for Shares delivered by the Company, the Agent
will pay the Company interest based on the effective overnight Federal Funds
rate.

     At each Representation Date (as defined below), the Company shall be deemed
to have affirmed each representation, warranty, covenant and other agreement
contained in this Agreement, and on each Filing Date (as defined below), the
Company shall affirm in writing each representation, warranty, covenant and
other agreement contained in this Agreement.  The Company covenants and agrees
with the Agent that on or prior to the second business day after the end of each
calendar week (each such week a "Reporting Period"), the Company will file a
prospectus supplement under the applicable paragraph of Rule 424(b) (each a
"Filing Date"), which prospectus supplement will set forth, with regard to such
Reporting Period, the dates included within the Reporting Period, the number of
shares of Common Stock and Preferred Stock, respectively, sold through the
Agent, the Net Proceeds to the Company and the compensation payable by the
Company to the Agent with respect to sales of Common Stock and Preferred Stock,
respectively (all as provided in writing by the Agent for inclusion in each such
prospectus supplement).  Any obligation of the Agent to use its reasonable
efforts to sell the Shares shall be subject to the continuing accuracy of the
representations and warranties of the Company herein, to the performance by the
Company of its obligations hereunder and to the continuing satisfaction of the
additional conditions specified in this Agreement.

     SECTION 3.  Representations and Warranties of the Company.  (a)  The
                 ---------------------------------------------           
Company represents and warrants to, and agrees with, the Agent that as of the
date hereof, as of each date of sale of Shares and as of each Settlement Date
and Filing Date, and as of any time that the Registration Statement or the
Prospectus shall be amended or supplemented (each of the times referenced above
is referred to herein as a "Representation Date"), as follows:

          (i) Compliance with Registration Requirements.  The Company meets the
              -----------------------------------------                        
     requirements for use of Form S-3 under the Securities Act of 1933 (the
     "Act") and the rules and regulations thereunder ("Rules and Regulations").
     A registration statement (as amended through the date hereof) on Form S-3
     (Registration No. 333-26865) with respect to, among other securities, the
     Stock, including a form of prospectus (as amended and supplemented through
     the date hereof), has been prepared by the Company in conformity with the
     requirements of the Act and the Rules and Regulations and filed under the
     Act and has become effective and no stop order suspending the effectiveness
     of the Registration Statement has been issued under the Act, and any
     request on the part of the Securities and Exchange Commission (the

                                       3

 
     "Commission") for additional information has been complied with.  Copies of
     such registration statement and prospectus, any such amendment or
     supplement and all documents incorporated by reference therein that were
     filed with the Commission on or prior to the date of this Agreement have
     been delivered to the Agent.  Such registration statement, as amended by
     each post-effective amendment thereto, if any, is referred to herein as the
     "Registration Statement" and the final form of prospectus included in the
     Registration Statement, as amended or supplemented from time to time, is
     referred to herein as the "Prospectus."  Any reference herein to the
     Registration Statement, the Prospectus, or any amendment or supplement
     thereto shall be deemed to refer to and include the documents incorporated
     (or deemed to be incorporated) by reference therein, and any reference
     herein to the terms "amend," "amendment" or "supplement" with respect to
     the Registration Statement or Prospectus shall be deemed to refer to and
     include the filing after the execution hereof of any document with the
     Commission deemed to be incorporated by reference therein.  For purposes of
     this Agreement, all references to the Registration Statement, Prospectus or
     preliminary prospectus or to any amendment or supplement thereto shall be
     deemed to include any copy filed with the Commission pursuant to its
     Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

          (ii) Conformity with Securities Act.  Each part of the Registration
               ------------------------------                                
     Statement, when such part became or becomes effective and at each
     Representation Date, and the Prospectus, on the date of filing thereof with
     the Commission and at each Representation Date, conformed or will conform
     in all material respects with the requirements of the Act and the Rules and
     Regulations; each part of the Registration Statement, when such part became
     or becomes effective and at each Representation Date, did not or will not
     contain an 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; and the Prospectus, on the date of filing thereof
     with the Commission and at each Representation Date, did not or will not
     include an untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; except that the
     foregoing shall not apply to statements in or omissions from any such
     document in reliance upon, and in conformity with, written information
     furnished to the Company by or on behalf of the Agent, specifically for use
     in the Registration Statement, the Prospectus or any amendment or
     supplement thereto.

          Each preliminary prospectus and the prospectus filed as part of the
     Registration Statement as originally filed or as part of any amendment
     thereto, or filed pursuant to Rule 424 under the Act, complied when so
     filed in all material respects with the Rules and Regulations, and the
     Registration Statement, each preliminary prospectus, the Prospectus and
     each amendment or supplement thereto delivered to the Agent for use in
     connection with this offering was or will be identical to the
     electronically transmitted copies thereof filed with the Commission
     pursuant to EDGAR, except to the extent permitted by Regulation S-T.

                                       4

 
          (iii)  Documents Incorporated by Reference.  The documents
                 -----------------------------------                
     incorporated by reference in the Registration Statement and the Prospectus,
     when they became or become effective under the Act or were or are filed
     with the Commission under the Exchange Act, as the case may be, conformed
     or will conform in all material respects with the requirements of the Act
     or the Exchange Act, as applicable, and the rules and regulations of the
     Commission thereunder and, when read together with the other information in
     the Registration Statement and the Prospectus, at the time the Registration
     Statement became effective, at the time the Prospectus was issued and at
     each Representation Date, did not and will not contain an untrue statement
     of a material fact or omit a material fact required to be stated therein or
     necessary to make the statements therein not misleading.

          (iv)   Financial Statements.  The financial statements of the Company
                 --------------------                                          
     and its subsidiaries, together with the related notes and schedules, set
     forth or incorporated by reference in the Registration Statement and
     Prospectus fairly present the financial condition and the results of
     operations and cash flows of the Company and its subsidiaries as of the
     dates indicated or for the periods therein specified and were prepared in
     conformity with generally accepted accounting principles consistently
     applied throughout the periods involved (except as otherwise stated
     therein).  The accountants who certified the financial statements and
     supporting schedules included in the Registration Statement are independent
     public accountants as required by the Act and the Rules and Regulations.

          (v) No Material Adverse Change in Business.  Since the respective
              --------------------------------------                       
     dates as of which information is given in the Registration Statement and
     the Prospectus, except as otherwise stated therein or contemplated thereby,
     (A) there has been no material adverse change in the condition, financial
     or otherwise, or in the earnings, business affairs or business prospects of
     the Company and its subsidiaries considered as one enterprise, whether or
     not arising in the ordinary course of business (a "Material Adverse
     Effect"), (B) there have been no transactions entered into by the Company
     or any of its subsidiaries, other than those in the ordinary course of
     business, which are material with respect to the Company and its
     subsidiaries, considered as one enterprise, and (C) there has been no
     dividend or distribution of any kind declared, paid or made by the Company
     on any class of its capital stock.

          (vi) Good Standing and Due Qualification.  The Company has been duly
               -----------------------------------                            
     incorporated and is validly existing as a corporation in good standing
     under the laws of the jurisdiction of its incorporation and has corporate
     power and authority to own, lease and operate its properties and to conduct
     its business as described in the Registration Statement and the Prospectus,
     to enter into and perform its obligations under this Agreement and to
     consummate the transactions contemplated in this Agreement, the
     Registration Statement and the Prospectus; the Company is duly qualified as
     a foreign corporation to transact business and is in good standing in each
     jurisdiction in which such qualification is required, whether by reason of
     the ownership

                                       5

 
     or leasing of property or the conduct of business, except where the failure
     to so qualify or be in good standing would not result in a Material Adverse
     Effect.

          (vii)  Good Standing of Subsidiaries.  Each significant subsidiary (as
                 -----------------------------                                  
     defined in Section 1-02 of Regulation S-X) (each, a "Significant
     Subsidiary") of the Company has been duly incorporated and is validly
     existing as a corporation in good standing under the laws of the
     jurisdiction of its incorporation, has corporate power and authority to
     own, lease and operate its properties and conduct its business as described
     in the Registration Statement and Prospectus and is duly qualified as a
     foreign corporation to transact business and is in good standing in each
     jurisdiction in which such qualification is required, whether by reason of
     the ownership or leasing of property or the conduct of business, except
     where the failure to so qualify and be in good standing would not have a
     Material Adverse Effect on the Company; and all of the issued and
     outstanding capital stock of each subsidiary has been duly authorized and
     validly issued, is fully paid and nonassessable and (except as set forth in
     Schedule 3.7 hereto or as otherwise stated in the Registration Statement)
     is owned by the Company, directly or through subsidiaries, free and clear
     of any security interest, mortgage, pledge, lien, encumbrance, claim or
     equity.  The Significant Subsidiaries of the Company are set forth in
     Schedule 3.7.

          (viii)  Capitalization.  The outstanding shares of capital stock of
                  --------------                                             
     the Company and the Stock have been duly authorized and are, or when issued
     as contemplated hereby will be, validly issued, fully paid and
     nonassessable and conform, or when so issued will conform, to the
     description thereof in the Prospectus.  Upon issuance and delivery of the
     Preferred Stock as contemplated by this Agreement, the Preferred Stock will
     be convertible, at the option of the holder thereof, into Common Stock.
     The shares of Common Stock issuable upon conversion have been duly
     authorized and reserved for issuance upon such conversion by all necessary
     corporate action and such shares of Common Stock, when issued upon such
     conversion will be validly issued, fully paid and non assessable.  The
     stockholders of the Company have no preemptive rights with respect to the
     Stock or the shares of Common Stock issuable upon conversion of the
     Preferred Stock.

          (ix) Absence of Proceedings.  Except as set forth in the Registration
               ----------------------                                          
     Statement and the Prospectus, there is not pending or, to the knowledge of
     the Company, threatened any action, suit or proceeding to which the Company
     or any of its subsidiaries is a party, before or by any court or
     governmental agency or body, that could reasonably be expected to result in
     a Material Adverse Effect, or which might reasonably be expected to
     materially and adversely affect the properties or assets thereof considered
     as a whole.

          (x) Accuracy of Exhibits.  There are no contracts or documents of the
              --------------------                                             
     Company or any of its subsidiaries that are required to be filed as
     exhibits to the Registration Statement or to any of the documents
     incorporated by reference therein by

                                       6

 
     the Act or the Exchange Act or by the rules and regulations of the
     Commission thereunder that have not been so filed.

          (xi) Due Authorization.  All necessary action has been duly and
               -----------------                                         
     validly taken by the Company to authorize the execution, delivery and
     performance of this Agreement.  This Agreement has been duly and validly
     authorized, executed and delivered by the Company.

          (xii)  Absence of Breach or Violation.  The performance of this
                 ------------------------------                          
     Agreement and the consummation of the transactions contemplated herein will
     not result in a breach or violation of any of the terms and provisions of,
     or constitute a default under, any agreement or instrument to which the
     Company or any of its subsidiaries is a party or by which it or any of its
     subsidiaries is bound or to which any of the property of the Company or any
     of its subsidiaries is subject, except for such breaches or defaults that
     would not, singly or in the aggregate, result in a Material Adverse Effect,
     or materially affect the Company's ability to perform its obligations under
     this Agreement, nor will such action result in the violation of the
     Company's charter or by-laws, or any statute or any order, rule or
     regulation of any court or governmental agency or body having jurisdiction
     over the Company or any of its subsidiaries or any of its properties; no
     consent, approval, authorization or order of, or filing with, any court or
     governmental agency or body is required for the consummation by the Company

     subsidiaries has (i) good and indefeasible title to all of the properties
     and assets described in the Prospectus as owned by it, free and clear of
     all liens, charges, encumbrances or restrictions, except such as are
     described in the Prospectus or are not material to the business, condition,
     financial or otherwise, or the earnings, business affairs or business
     prospects of the Company and its subsidiaries considered as one enterprise,

     Company and its subsidiaries considered as one enterprise, (iv) no reason

     regulation required to be described in the Registration Statement and

     which the Company or any of its subsidiaries is a party are valid and

     names presently employed by them in connection with the business now
     operated by them, and neither the Company nor any of its subsidiaries has
     received any notice of infringement of or conflict with asserted rights of
     others with respect to any of the foregoing which, if singly or in the
     aggregate, if the subject of an unfavorable decision, ruling or finding,
     would result a Material Effect.

          (xv) Absence of Violations.  The Company and its subsidiaries have not
               ---------------------

     governmental agency, department or authority, including, without
     limitation, environmental laws.  Neither the Company nor any of its
     subsidiaries has received any notice to the effect that, or otherwise been

agrees with the Agent that:

                                       8

 
          (a) Compliance with Securities Regulations and Commission Requests.
              --------------------------------------------------------------  
During the period in which a prospectus relating to the Shares is required to be
delivered under the Act, the Company will notify the Agent promptly of the time
when any subsequent amendment to the Registration Statement has become effective
or any subsequent supplement to the Prospectus has been filed and of any request
by the Commission for any amendment or supplement to the Registration Statement
or Prospectus or for additional information; it will prepare and file with the
Commission, promptly upon the Agent's request, any amendments or supplements to
the Registration Statement or Prospectus that, in the Agent's reasonable
opinion, may be necessary or advisable in connection with the distribution of
the Shares by the Agent; the Company will not file any amendment or supplement
to the Registration Statement or Prospectus (other than any prospectus
supplement relating to the offering of other securities registered under the
Registration Statement) unless a copy thereof has been submitted to the Agent a
reasonable period of time before the filing and the Agent has not reasonably
objected thereto; and it will furnish to the Agent at the time of filing thereof
a copy of any document that upon filing is deemed to be incorporated by
reference in the Registration Statement or Prospectus; and the Company will
cause each amendment or supplement to the Prospectus to be filed with the
Commission as required pursuant to the applicable paragraph of Rule 424(b) of
the Rules and Regulations or, in the case of any document to be incorporated
therein by reference, to be filed with the Commission as required pursuant to
the Exchange Act, within the time period prescribed.

              ---------------------------                                     
promptly after it shall receive notice or obtain knowledge thereof, of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement, of the suspension of the qualification of the Shares for
offering or sale in any jurisdiction, or of the initiation or threatening of any
proceeding for any such purpose; and it will promptly use every reasonable
effort to prevent the issuance of any stop order or to obtain its withdrawal if
such a stop order should be issued.

          (c) Continued Compliance with Securities Laws.  Within the time during
              -----------------------------------------                         
which a prospectus relating to the Shares is required to be delivered under the
Act, the Company will comply as far as it is able with all requirements imposed
upon it by the Act and by the Rules and Regulations, as from time to time in
force, so far as necessary to permit the continuance of sales of or dealings in
the Shares as contemplated by the provisions hereof and the Prospectus. If
during such period any event occurs as a result of which the Prospectus as then
amended or supplemented would include an untrue statement of a material fact or
omit to state a material fact necessary to make the statements therein, in the
light of the circumstances then existing, not misleading, or if during such
period it is necessary to amend or supplement the Registration Statement or
Prospectus to comply with the Act, the Company will promptly notify the Agent to
suspend the offering of Shares during such period and the Company will amend or
supplement the Registration Statement or Prospectus (at the expense of the
Company, unless the misstatements or omissions in question were made solely in
reliance on written information furnished to the Company by the Agent expressly
for use in the Registration Statement or Prospectus in which case such amendment
or supplement shall be at

                                       9

              ----------------------                                           
qualify the Shares for sale under the securities laws of such jurisdictions as
the Agent designates and to continue such qualifications in effect so long as
required for the distribution of the Shares, except that the Company shall not
be required in connection therewith to qualify as a foreign corporation or to
execute a general consent to service of process in any jurisdiction.

          (e) Delivery of Registration Statement.  The Company will furnish to
              ----------------------------------

Registration Statement, the Prospectus (including all documents incorporated by
reference therein) and all amendments and supplements to the Registration
Statement or Prospectus that are filed with the Commission during the period in
which a prospectus relating to the Shares is required to be delivered under the
Act (including all documents filed with the Commission during such period that
are deemed to be incorporated by reference therein), in each case as soon as
available and in such quantities as the Agent may from time to time reasonably
request and will also furnish copies of the Prospectus to the NYSE in accordance
with Rule 153 of the Rules and Regulations.

          (f) Availability of Earnings Statement.  The Company will make

event not later than 15 months after the end of the Company's current fiscal
quarter, an earnings statement (which need not be audited) covering a 12-month
period that satisfies the provisions of Section 11(a) of the Act and Rule 158 of

all of its expenses incident to the performance of its obligations hereunder

shelf program established by this Agreement. The Agent will pay its own out-of-
pocket costs and expenses incurred in connection with the entering into of this
Agreement and the transactions contemplated by this Agreement, including,

and (b) suspending activity under this program for such period of time as may
reasonably be determined by agreement of the Company and the Agent; provided,
                                                                    --------

     SECTION 7.  Indemnification.
                 --------------- 

     (a) Indemnification of the Agent.  The Company agrees to indemnify and hold
         ----------------------------                                           
harmless the Agent and each person, if any, who controls the Agent within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act as follows:

          (i)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of an untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     or the omission or alleged omission therefrom of a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, or arising out of an untrue statement or alleged untrue
     statement of a material fact included in any preliminary prospectus or the
     Prospectus, or the omission or alleged omission therefrom of a material
     fact necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading;

          (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, provided that (subject to Section
     7(d) hereof) any such settlement is effected with the written consent of
     the Company; and

          (iii)  against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by the Agent), reasonably
     incurred in investigating, preparing or defending against any litigation,
     or any investigation or proceeding by any governmental agency or body,
     commenced or threatened, or any claim whatsoever based upon any such untrue
     statement or omission, or any such alleged untrue statement or omission, to
     the extent that any such expense is not paid under subparagraph (i) or (ii)
     above;

provided, however, that this indemnity does not apply to any loss, liability,
- --------  -------                                                            
claim, damage or expense to the extent arising out of an untrue statement or
omission or alleged untrue state ment or omission made in reliance upon and in
conformity with written information furnished to the Company by the Agent
expressly for use in the Registration Statement or any preliminary prospectus or
the Prospectus.

                                      15

 
     (b) Indemnification of Company, Directors and Officers.  The Agent agrees
         --------------------------------------------------                   
to indemnify and hold harmless the Company, its directors, each of its officers
who signed the Registration Statement and each person, if any, who controls the
Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act against any and all loss, liability, claim, damage and expense
described in the indemnity contained in Section 7(a) hereof, as incurred, but
only with respect to untrue statements or omissions, or alleged untrue
statements or omissions, made in the Registration Statement or any preliminary
prospectus or the Prospectus in reliance upon and in conformity with written
information furnished to the Company by the Agent expressly for use in the
Registration Statement or such preliminary prospectus or the Prospectus.

     (c) Actions Against Parties; Notification.  Each indemnified party shall
         -------------------------------------                               
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  In the case of parties indemnified pursuant to Section 7(a) hereof,
counsel to the indemnified parties shall be selected by the Agent and, in the
case of parties indemnified pursuant to Section 7(b) hereof, counsel to the
indemnified parties shall be selected by the Company.  An indemnifying party may
participate at its own expense in the defense of any such action; provided,
                                                                  -------- 
however, that counsel to the indemnifying party shall not (except with the
- -------                                                                   
consent of the indemnified party) also be counsel to the indemnified party.  In
no event shall the indemnifying parties be liable for fees and expenses of more
than one counsel (in addition to any local counsel) separate from their own
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.

     No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 7 or Section 8 hereof (whether or not the indemnified parties
are actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

     (d) Settlement without Consent if Failure to Reimburse.  If at any time an
         --------------------------------------------------                    
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 7(a)(ii) effected without its written consent if (i) such settlement is
entered into more than sixty (60) days after receipt by such indemnifying party
of the aforesaid request, (ii) such indemnifying party shall have received

                                      16

 
notice of the terms of such settlement at least forty-five (45) days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement.

     SECTION 8.  Contribution.
                 ------------ 

     If the indemnification provided for in Section 7 hereof is for any reason
unavailable to or insufficient to hold harmless an indemnified party in respect
of any losses, liabilities, claims, damages or expenses referred to therein,
then each indemnifying party shall contribute to the aggregate amount of such
losses, liabilities, claims, damages and expenses incurred by such indemnified
party, as incurred, (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company, on the one hand, and the Agent, on
the other hand, from the offering of the Shares that was the subject of the
claim for indemnification or (ii) if the allocation provided by clause (i) is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company on the one hand and the Agent on the other hand in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

     The relative benefits received by the Company on the one hand and the Agent
on the other hand in connection with the offering of the Shares that was the
subject of the claim for indemnification shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of such
Shares (before deducting expenses) received by the Company and the total
compensation (before deducting expenses) received by the Agent from the sale of
Shares on behalf of the Company bears to the aggregate initial offering price of
such Shares.

     The relative fault of the Company, on the one hand, and the Agent, on the
other hand, shall be determined by reference to, among other things, whether any
untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by the Company
or by the Agent and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

     The Company and the Agent agree that it would not be just and equitable if
contribution pursuant to this Section 8 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 8.  The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an
indemnified party and referred to above in this Section 8 shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any applicable untrue or alleged
untrue statement or omission or alleged omission.

                                      17

 
     Notwithstanding the provisions of this Section 8, the Agent shall not be
required to contribute any amount in excess of the amount by which the total
[discount or] commission received in connection with the offering of the Shares
that was the subject of the claim for indemnification exceeds the amount of any
damages which the Agent has otherwise been required to pay by reason of any
applicable untrue or alleged untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Act) shall be entitled to contribution from any person who
was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 8, each person, if any, who controls the Agent
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
shall have the same rights to contribution as the Agent, and each director of
the Company, each officer of the Company who signed the Registration Statement,
and each person, if any, who controls the Company within the meaning of Section
15 of the Act or Section 20 of the Exchange Act shall have the same rights to
contribution as the Company.

     SECTION 9.  Representations and Agreements to Survive Delivery.  All
                 --------------------------------------------------      
representations, warranties and agreements contained in this Agreement or in
certificates of officers of the Company submitted pursuant hereto, shall remain
operative and in full force and effect regardless of any investigation made by
or on behalf of the Agent or any controlling person of the Agent, or by or on
behalf of the Company, and shall survive delivery of and payment for the Shares.

     SECTION 10.  Termination.  (a)  The Agent shall have the right by giving
                  -----------                                                
notice as hereinafter specified at any time at or prior to any Settlement Date,
to terminate this Agreement if (i) there has been, since the respective dates as
of which information is given in the Prospectus, any material adverse change, in
the condition, financial or otherwise, or in the earnings, business affairs, or
business prospects of the Company and its subsidiaries considered as one
enterprise, whether or not arising in the ordinary course of business, (ii) the
Company shall have failed, refused or been unable, at or prior to the Settlement
Date, to perform any agreement on its part to be performed hereunder, (iii) any
other condition of the Agent's obligations hereunder is not fulfilled, (iv) any
suspension or limitation of trading in the Stock on the NYSE, or any setting of
minimum prices for trading of the Stock on such exchange, shall have occurred,
or if trading generally on the NYSE has been suspended or materially limited, or
minimum or maximum prices for trading have been fixed, or maximum ranges for
prices have been required, by the NYSE or by order of the Commission or any
other governmental authority, (v) any banking moratorium shall have been
declared by Federal or New York authorities or (vi) there has occurred any
material adverse change in the financial markets in the United States, an
outbreak or escalation of hostilities or other calamity or crisis or any change
or development involving a prospective change in national or international
political, financial or economic conditions, in each case the effect of which is
such as to make it, in the judgment of the Agent, impractical or inadvisable to
proceed with the completion of the sale of and payment for the Shares to be sold
by the Agent on behalf of

                                      18

 
the Company.  Any such termination shall be without liability of any party to
any other party except that the provisions of Section 4(g), Section 7, Section 8
and Section 9 hereof shall remain in full force and effect notwithstanding such
termination.  If the Agent elects to terminate this Agreement as provided in
this Section, the Agent shall provide the required notice as specified herein.

     (b) The Company shall have the right, by giving notice as hereinafter
specified, to terminate this Agreement in its sole discretion on the first
anniversary of the date of this Agreement.  At any time after the first
anniversary of the date of this Agreement, the Company shall have the right, by
giving thirty (30) days prior written notice as hereinafter specified, to
terminate this Agreement in its sole discretion.  Any such termination shall be
without liability of any party to any other party except that the provisions of
Section 4(g), Section 7, Section 8 and Section 9 hereof shall remain in full
force and effect notwithstanding such termination.

     (c) The Agent shall have the right, by giving notice as hereinafter
specified, to terminate this Agreement in its sole discretion at any time after
the first anniversary of the date of this Agreement by giving thirty (30) days
prior written notice as hereinafter specified.  Any such termination shall be
without liability of any party to any other party except that the provisions of
Section 4(g), Section 7, Section 8 and Section 9 hereof shall remain in full
force and effect notwithstanding such termination.

     (d) This Agreement shall remain in full force and effect unless terminated
pursuant to Sections 10(a), (b) or (c) above or otherwise by mutual agreement of
the parties; provided that any such termination by mutual agreement shall in all
cases be deemed to provide that Section 4(g), Section 7, Section 8 and Section 9
shall remain in full force and effect.

     (e) Any termination of this Agreement shall be effective on the date
specified in such notice of termination; provided that such termination shall
                                         --------                            
not be effective until the close of business on the date of receipt of such
notice by the Agent or the Company, as the case may be.  If such termination
shall occur prior to the Settlement Date for any Shares, subject to Section
10(a) above, such Shares shall settle in accordance with the provisions of
Section 2 hereof.

     SECTION 11.  Notices.  All notices or communications hereunder shall be in
