                                 SALE AGREEMENT
                                       TO
                         ALPHA/ZFT GENERAL PARTNERSHIP



     THIS AGREEMENT, dated as of the 1st day of July, 1998, by and between
SAMSTOCK/SZRT, L.L.C., a Delaware limited liability company, as Seller
(hereinafter referred to as the "Seller"), and ALPHA/ZFT GENERAL PARTNERSHIP,
an Illinois general partnership, as Purchaser (hereinafter referred to as the
"Purchaser"):

                              W I T N E S S E T H:

     WHEREAS, Seller is the owner of at least Five Hundred Seventy-Eight
Thousand Six Hundred Forty-Nine (578,649) shares of common stock (hereinafter
sometimes referred to as the "Subject Shares") of CNA Surety Corporation
(hereinafter referred to as the "Corporation"), a Delaware corporation; and

     WHEREAS, Seller, upon the advice and with the consent of Samuel Zell, the
Grantor, trustee and beneficiary of the Samuel Zell Revocable Trust, the sole
member of the Seller, desires to avoid the uncertainties in connection with the
holding of common stock of the Corporation and risk in preservation of the
principal value of common stock of the Corporation, and desires to assure
itself now of the receipt of a certain fixed annual income for the full term of
the natural life of Samuel Zell; and

     WHEREAS, Seller is willing to sell, assign, transfer, convey and set over
the Subject Shares to Purchaser, provided that Purchaser will agree to pay to
Seller a sum certain per annum for the full term of Samuel Zell's life,
regardless of the value from time to time of the Subject Shares and regardless
of the amount of income therefrom received from time to time by Purchaser; and

     WHEREAS, Purchaser desires to purchase the Subject Shares and is willing
to pay to Seller a sum certain for the full term of Samuel Zell's life; and

     WHEREAS, Seller and Purchaser desire to sell and purchase the Subject
Shares on the terms contained herein, which both parties acknowledge reasonably
reflect the terms on which unrelated parties would enter into such sale and
purchase; and

     NOW THEREFORE, it is mutually agreed as follows:

     1.  Sale.  Seller hereby sells, assigns, transfers, conveys and sets over
absolutely to Purchaser Five Hundred Seventy-Eight Thousand Six Hundred 
Forty-Nine (578,649) shares of the common stock of the Corporation.  Purchaser
agrees to pay Seller the fair market value of the Subject Shares sold
hereunder, as determined for federal estate tax purposes as of the date hereof,
payable as provided in Section 3 hereof.

     2.  Delivery of Certificate.  Seller hereby conveys legal and equitable
title in the Subject Shares to Purchaser, and Seller agrees to provide delivery
of certificates or other materials evidencing the Subject Shares within a
reasonable time hereof, along with executed stock powers or other documents of
transfer so that the Subject Shares can be transferred to Purchaser on the
books of the Corporation.

     3.  Annuity.  (a) Purchaser hereby agrees to pay or to cause to be paid
annually to Seller (or to anyone Seller appoints pursuant to Section 11 hereof)
for and during the full term of the natural life of Samuel Zell, the Grantor,
trustee and beneficiary of the Samuel Zell Revocable Trust, the sole

member of the Seller, a "sum certain", as defined in subsection 3(b) hereof, in
lawful currency of the United States of America, as provided in Section 6 
hereof.

     (b) As used herein, the "sum certain" payable annually hereunder shall be
the amount which is equal to the result obtained by dividing the annuity factor
(calculated as provided in subsection 3(d) hereof) into the fair market value
of the Subject Shares being sold hereunder.  Said sum certain shall be computed
as shown on Exhibit A, a sample of which is attached hereto and incorporated
herein by this reference.

     (c) For purposes of Section 3 hereof, the "fair market value" of the
Subject Shares being sold hereunder shall be the mean between the highest and
lowest quoted selling prices per share of the common stock of the Corporation
on the date hereof multiplied by the number of Subject Shares.  Purchaser shall
deliver to Seller within five (5) business days of the date hereof a signed
statement of the fair market value of the Subject Shares being sold hereunder
and the computation of the sum certain described in subsection 3(b) hereof and
as shown on Exhibit A.  Seller shall either sign such statement in acceptance
thereof or shall have five (5) business days to object in writing to such
computation, but if Seller does not so object, the sum certain shall be deemed
part of this Agreement.

     (d) As provided in Section 25.2512-5(d)(2)(iv) of the Treasury Department
Regulations (referred to herein as the "Regulations"), the annuity factor to be
used hereunder shall be calculated by (i) first, locating in Table S of Section
20.2031-7(d)(6) of the Regulations (referred to herein as "Table S") the
remainder factor for a single life annuity for a person of Samuel Zell's age as
of the date hereof at the interest rate which is one hundred twenty percent
(120%) of the applicable federal mid-term rate in effect under Section 1274(d)
of the Internal Revenue Code of 1986 (referred to herein as the "Code") for the


                                    - 3 -








                                 Page 17 of 61

 
<PAGE>   4

date of execution of this Agreement, (ii) subtracting such remainder factor
from one (1) and (iii) dividing the difference by one hundred twenty percent
(120%) of said applicable federal mid-term rate.

     4.  Automatic Readjustment of Value.  Purchaser and Seller intend that the
sale, transfer, assignment and delivery of Seller's interest in the Subject
Shares hereunder to the Purchaser shall be made for their full fair market
value and the annuity payments to be paid by the Purchaser to the Seller shall
be full and fair consideration for the within transaction.  In the event that
the fair market value of the Subject Shares or the sum certain shall be finally
determined (such event hereinafter referred to as "Final Determination"), for
any reason whatsoever, by a final order of any court of competent jurisdiction
or by a final decision of any administrative agency of the United States of
America (from which order or decision no appeal is taken), to be greater or
less than the fair market value as determined in accordance with this Agreement,
then the annual annuity payments shall be recomputed using the value 
established by such Final Determination.  With respect to each annuity payment
actually made prior to the date of said Final Determination (the "Final 
Determination Date"), if the fair market value of the Subject Shares or the 
sum certain is increased the Purchaser agrees to pay to the Seller, and if the 
fair market value of the Subject Shares or the sum certain is decreased the 
Seller agrees to pay to the Purchaser, an amount equal to the difference 
between each annuity payment actually made and the annuity payment which would
have been paid had this newly determined value been used as the fair market 
value of the Subject Shares or the sum certain on the date of execution of this 
Agreement.  In either event, said difference shall be payable within one 
hundred eighty (180) days from the Final Determination Date with interest 
accruing at the Contract Interest Rate (as defined in Section 5 hereof) from 
the date such prior annuity payment was actually made (referred to herein as
a "Start Date") until such additional amount is paid.  The failure of Purchaser
to pay in full, within two (2) years of the Final Determination Date, any such
additional amount, plus interest thereon, due to Seller shall constitute a


                                    - 4 -
 






                                 Page 18 of 61

<PAGE>   5

"Default" hereunder and the second anniversary of the Final Determination Date
shall be a "Default Date" hereunder.  All annuity payments after the Final
Determination Date shall be made as if the newly determined value had been the
fair market value of the Subject Shares or the sum certain on the date of this
Agreement.

     5.  Contract Interest Rate.  As used herein, the Contract Interest Rate is
one hundred twenty percent (120%) of the rate listed below in subparagraph (a),
(b) or (c), compounded semi-annually, which shall result in the maximum accrued
interest when the amount due is paid:


            (a)  the applicable federal mid-term rate in effect under Section
                 1274(d) of the Code for the date of execution of this 
                 Agreement;

            (b)  the highest applicable federal rate in effect under Section 
                 1274(d) of the Code for the applicable Start Date; or

            (c)  for each month for which interest is payable, the applicable 
                 federal short-term rate in effect under Section 1274(d) of the
                 Code for such month; provided, however, that if interest shall
                 be payable with respect to any complete calendar year, then the
                 blended annual rate, calculated pursuant to the provisions of 
                 Revenue Ruling 86-17, 1986-1 Cumulative Bulletin 377, shall be
                 substituted for the twelve (12) separate monthly rates for that
                 year.

     6.  Payment of Annuity.  Each annual annuity payment shall be due and
payable on the anniversary date of this Agreement, with the first such
installment due and payable on the anniversary of this Agreement in the year
following the year of execution of this Agreement and the last such installment
due and payable on the anniversary of this Agreement in the year in which the
death of Samuel Zell shall occur but only if Samuel Zell shall be alive on such
anniversary date, it being distinctly understood that such payments are to be
made only for and during the natural life of Samuel Zell without regard to
whether the aggregate amount paid be more or less than the present fair market
value of the


                                    - 5 -
 






                                 Page 19 of 61
<PAGE>   6

Subject Shares transferred by Seller hereunder, and that no annuity payments
shall be due and payable hereunder after the death of Samuel Zell.

     7.  Failure to Make Payment; Events of Default.  Interest on an annuity
payment not made in full by Purchaser hereunder when due shall be accrued at
the Contract Interest Rate, from the date such annuity payment is due (referred
to herein as a "Start Date") until paid, and each such unpaid payment or
portion thereof shall constitute a liability of Purchaser immediately due and
payable in addition to its obligation to make the regular annual payments 
solely during the life of Samuel Zell pursuant to Section 6 hereof.  Any
failure to make an annuity payment, or portion thereof, within two (2) years of
the date when such annuity payment is due shall constitute a "Default"
hereunder and the second anniversary of the date when such annuity payment is
due shall be a "Default Date" hereunder.  Additionally, an arrearage for at
least one (1) year of any portion or all of two (2) annuity payments shall
constitute a "Default" hereunder and the first date on which there shall be two
(2) annuity payments, or portions thereof, in arrears for at least one (1) year
shall be a "Default Date" hereunder.

     8.  Remedy in Event of Default.  Purchaser agrees that, in the event of a
Default, in addition to any amounts due prior to the Default Date with respect
to such Default plus interest on such amounts, "the anticipated aggregate of
annuity payments" shall be due and payable on demand.  For purposes of this
Agreement, the phrase "the anticipated aggregate of annuity payments" shall
mean the present worth of Seller receiving an annual annuity equal to the sum
certain for the full term of Samuel Zell's anticipated life as of such Default
Date, such worth to be determined by multiplying the sum certain by the annuity
factor of a single life annuity for a person of Samuel Zell's age as of such
Default Date.  Said annuity factor shall be calculated as provided in
subsection 3(d) hereof except that such Default Date shall be substituted for
the date of this Agreement in said calculation.  The anticipated


                                    - 6 -
 







                                 Page 20 of 61

<PAGE>   7

aggregate of annuity payments shall accrue interest at the Contract Interest
Rate from the Default Date (also referred to herein as a "Start Date") until
paid.

     9.  Absence of Collateral.  Purchaser and Seller understand that, in the
event of a Default, the remedy described above in Section 8 shall constitute
the sole and exclusive remedy available to Seller.  Accordingly, Purchaser and
Seller expressly agree that neither such Section 8 nor any other provision of
this Agreement shall create a security interest in the Subject Shares or in any
other assets of Purchaser now owned or hereafter acquired, and further that no
restriction shall be imposed hereby upon the alienation of the Subject Shares
or other assets by Purchaser.  Purchaser agrees not to take any actions that
will impair or otherwise inhibit the Purchaser's payment of other liabilities.

     10.  Age.  Samuel Zell was born on September 28, 1941, and, based upon his
age as of his birthday nearest to the date of this Agreement, is considered to
be the age of fifty-seven (57) years for purposes hereof.  Seller agrees to
furnish to Purchaser proof of Samuel Zell's age before payment of the first
annuity payment if Purchaser so requests in writing.

     11.  Appointment of Other Payees.  Seller shall have the right to appoint,
at any time and from time to time, any other payee to be the recipient of all
or any one or more annual annuity payments by notifying Purchaser in writing of
the recipient so appointed and any such notification shall, to the extent it
shall be inconsistent with any prior notification, modify and supersede any
prior notification.  If any such payee shall die or otherwise cease to exist
before the death of Samuel Zell, the interest of such payee shall revert to
Seller.

     12.  Construction.  The parties agree that all matters pertaining to the
validity, construction and effect of this Agreement shall be determined in
accordance with the laws of the State of Illinois.  This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their permitted
successors and assigns hereunder.

     13.  Notice.  All notices, statements, requests and demands given to or
made upon Seller or Purchaser in accordance with the provisions of this
Agreement shall be deemed to have been given or made: (i) if mailed, two
business days after deposit in the mail, postage prepaid; (ii) in the case of
delivery via messenger or nationally recognized courier service, on the date
actually delivered; or (iii) in the case of notice via telecopy, on the date
transmitted, in any case to the last known addresses of the parties or such
other addresses at which the parties shall from time to time notify one
another.

     14.  Counterparts.  This Agreement may be executed in any number of
counterpart copies, each of which shall be deemed an original for all purposes,
but all of which shall constitute one and the same agreement.

Dear Sirs:

     Certain stockholders named in Schedule II hereto (the "Selling 
Shareholders") of CNA Surety Corporation (the "Company"), severally propose to
sell to the several underwriters named in Schedule I hereto (the 
"Underwriters") an aggregate of 4,188,129 shares of Common Stock, par value
$.01 per share, of the Company (the "Firm Shares"), each Selling Shareholder
selling the amount of Firm Shares set forth opposite such Selling Shareholder's
name set forth on Schedule II hereto.  The Company also proposes to issue and
sell to the several Underwriters not more than 628,219 additional shares of
Common Stock, par value $.01 per share, of the Company (the "Additional
Shares"), if requested by the Underwriters as provided in Section 2 hereof.
The Firm Shares and the Additional Shares are herein collectively called the
"Shares".  The shares of common stock of the Company to be outstanding after
giving effect to the sales contemplated hereby are hereinafter referred to as
the "Common Stock".  The Company and the Selling Shareholders are hereinafter
collectively called the "Sellers".

     SECTION 1.  Registration Statement and Prospectus.  The Company has
prepared and filed with the Securities and Exchange Commission (the
"Commission") in accordance with the provisions of the Securities Act of 1933,
as amended, and the rules and

                                                                            2  




regulations of the Commission thereunder (collectively, the "Act"), a
registration statement on Form S-1 (No. 333-56063) including a prospectus
relating to the Shares.  The registration statement, as amended at the time
when it became effective, including the information (if any) deemed to be part
of the registration statement at the time of effectiveness pursuant to Rule
430A under the Act, is hereinafter referred to as the "Registration Statement";
and the prospectus in the form first used to confirm sales of Shares is
hereinafter referred to as the "Prospectus".  If the company has filed or is
requested pursuant to the terms hereof to file a registration statement
pursuant to Rule 462(b) under the Act registering additional shares of Common
Stock (a "Rule 462(b) Registration Statement"), then, unless otherwise
specified, any reference herein to the term "Registration Statement" shall be
deemed to include such Rule 462(b) Registration Statement.

     SECTION 2.  Agreements to Sell and Purchase and Lock-Up Agreements.  On
the basis of the representations and warranties contained in this Agreement,
and subject to its terms and conditions, (i) each Selling Shareholder agrees,
severally and not jointly, to sell to the Underwriters the number of Firm
Shares set forth opposite such Selling Shareholder's name in Schedule II hereto
and (ii) each Underwriter agrees, severally and not jointly, to purchase from
each Selling Shareholder at a price per Firm Share of $13.06 (the "Purchase
Price") the number of Firm Shares (subject to such adjustments to eliminate
fractional shares as you may determine) which bears the same proportion to the
total number of Firm Shares to be sold by such Selling Shareholder as the
number of Firm Shares set forth opposite the name of such Underwriter in
Schedule I hereto bears to the total number of Firm Shares.

     On the basis of the representations and warranties contained in this
Agreement, and subject to the terms and conditions hereof, (i) the Company
agrees to issue and sell up to 628,219 Additional Shares and (ii) the
Underwriters shall have the right to purchase, severally and not jointly, up to
an aggregate of 628,219 Additional Shares from the Company at the Purchase
Price.  Additional Shares may be purchased solely for the purpose of covering
over-allotments made in connection with the offering of the Firm Shares.  The
Underwriters may exercise their right to purchase Additional Shares in whole or
in part from time to time by giving written notice thereof to the Company
within 30 days after the date of this Agreement.  You shall give any such
notice on behalf of the Underwriters and such notice shall specify the
aggregate number of Additional Shares to be purchased pursuant to such exercise
and the date for payment and delivery thereof.  The date specified in any such
notice shall be a business day (i) no earlier than the Closing Date (as
hereinafter defined), (ii) no later than ten business days after such notice
has been given and (iii) no earlier than three business days after such notice
has been given.  If any Additional Shares are to be purchased, each
Underwriter, severally and not jointly, agrees to purchase from the Company the
number of Additional Shares (subject to such adjustments to eliminate
fractional shares as you may determine) which bears the same proportion to the
total number of Additional Shares to be purchased from the Company as the
number of Firm Shares set forth opposite the name of such Underwriter in
Schedule I bears to the total number of Firm Shares.

     Each Seller hereby agrees not to (i) offer, pledge, sell, contract to
sell, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase, or otherwise transfer

damages, liabilities or judgments are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information
relating to any Underwriter furnished in writing to the Company by such
Underwriter through you expressly for use therein; provided, however, that the
foregoing indemnity agreement with respect to any preliminary prospectus shall
not inure to the benefit of any Underwriter who failed to deliver a Prospectus
(as then amended or supplemented, provided by the Company to the several
Underwriters in the requisite quantity and on a timely basis to permit proper
delivery on or prior to the Closing Date) to the person asserting any losses,
claims, damages and liabilities and judgments caused by any untrue statement or
alleged untrue statement of a material fact contained in any preliminary
prospectus, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, if such material misstatement or omission or alleged
material misstatement or omission was cured in such Prospectus and such
Prospectus was required by law to be delivered at or prior to the written
confirmation of sale to such person.

     (b)  Each of the Selling Shareholders agrees, severally and not jointly,
to indemnify and hold harmless each Underwriter, its directors, its officers
and each person, if any, who controls any Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act to the same extent as
the foregoing indemnity from the Company to each Underwriter, but only with
reference to information relating to such Selling Shareholder furnished in
writing by or on behalf such Selling Shareholder expressly for use in the
Registration Statement, the Prospectus or any preliminary prospectus.
Notwithstanding the foregoing, the aggregate liability of any Selling
Shareholder pursuant to this Section 8(b) shall be limited to an amount equal
to the total proceeds (before deducting underwriting discounts and commissions
and expenses) received by such Selling Shareholder from the Underwriters for
the sale of the Firm Shares sold by such Selling Shareholder hereunder;
provided, however, that the foregoing indemnity agreement with respect to any
preliminary prospectus shall not inure to the benefit of any Underwriter from
whom the person asserting any such losses, claims, damages and liabilities and
judgments purchased Shares, or any person controlling such Underwriter, if a
copy of the Prospectus (as then amended or supplemented if the Company shall
have furnished any amendments or supplements thereto) was not sent or

                                                                             17



given by or on behalf of such Underwriter to such person, if required by law so
to have been delivered, at or prior to the written confirmation of the sale of
the Shares to such person, and if the Prospectus (as so amended and
supplemented) would have cured the defect giving rise to such loss, claim,
damage, liability or judgment. The Company and the Selling Shareholders may
enter into other agreements amongst themselves with respect to the
indemnification obligations hereunder, provided that such agreements shall not
affect the indemnification obligations of the Company and the Selling
Shareholders to the several Underwriters under this Agreement.

     (c)  Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers who sign the
Registration Statement, each person, if any, who controls the Company within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each
Selling Shareholder and each person, if any, who controls such Selling
Shareholder within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act to the same extent as the foregoing indemnity from the Company and
the Selling Shareholders to such Underwriter but only with reference to
information relating to such Underwriter furnished in writing to the Company by
such Underwriter through you expressly for use in the Registration Statement
(or any amendment thereto), the Prospectus (or any amendment or supplement
thereto) or any preliminary prospectus.

     (d)  In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a), 8(b) or 8(c) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying party") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) or 8(b) and 8(c), the Underwriter shall not be required
to assume the defense of such action pursuant to this Section 8(d), but may
employ separate counsel and participate in the defense thereof, but the fees
and expenses of such counsel, except as provided below, shall be at the expense
of such Underwriter). Any indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of the
indemnified party unless (i) the employment of such counsel shall have been
specifically authorized in writing by the indemnifying party, (ii) the
indemnifying party shall have failed to assume the defense of such action or
employ counsel reasonably satisfactory to the indemnified party or (iii) the
named parties to any such action (including any impleaded parties) include both
the indemnified party and the indemnifying party, and the indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the indemnifying party (in which case the indemnifying party shall
not have the right to assume the defense of such action on behalf of the
indemnified party). In any such case, the indemnifying party shall not, in
connection with any one action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for (i) the fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) for all
Underwriters, their officers and directors and all persons, if any, who control
any Underwriter

                                                                            18




within the meaning of either Section 15 of the Act or Section 20 of the
Exchange Act, (ii) the fees and expenses of more than one separate firm of
attorneys (in addition to any local counsel) for the Company, its directors,
its officers who sign the Registration Statement and all persons, if any, who
control the Company within the meaning of either such Section and (iii) the
fees and expenses of more than one separate firm of attorneys (in addition to
any local counsel) for all Selling Shareholders and all persons, if any, who
control any Selling Shareholder within the meaning of either such Section, and
all such fees and expenses shall be reimbursed as they are incurred. In the
case of any such separate firm for the Underwriters, their officers and
directors and such control persons of any Underwriters, such firm shall be
designated in writing by Donaldson, Lufkin & Jenrette Securities Corporation.
In the case of any such separate firm for the Company and such directors,
officers and control persons of the Company, such firm shall be designated in
writing by the Company. In the case of any such separate firm for the Selling
Shareholders and such control persons of any Selling Shareholders, such firm
shall be designated in writing by the Attorneys. The indemnifying party shall
indemnify and hold harmless the indemnified party from and against any and all
losses, claims, damages, liabilities and judgments by reason of any settlement
of any action (i) effected with its written consent or (ii) effected without
its written consent if the settlement is entered into more than twenty business
days after the indemnifying party shall have received a request from the
indemnified party for reimbursement for the fees and expenses of counsel (in
any case where such fees and expenses are at the expense of the indemnifying
party) and, prior to the date of such settlement, the indemnifying party shall
have failed to comply with such reimbursement request. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement or compromise of, or consent to the entry of judgment with respect
to, any pending or threatened action in respect of which the indemnified party
is or could have been a party and indemnity or contribution may be or could
have been sought hereunder by the indemnified party, unless such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified
party from all liability on claims that are or could have been the subject
matter of such action 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 the
indemnified party.

     (e)  To the extent the indemnification provided for in this Section 8 is
unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in the case of
the Company (x) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Selling Shareholders on the one hand
and the Underwriters on the other hand from the offering of the Shares or (y)
if the allocation provided by clause 8(e)(i)(x) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause 8(e)(i)(x) above but also the relative
fault of the Company and the Selling Shareholders on the one hand and the
Underwriters on the other hand in connection with the statements or omissions
which resulted in such losses, claims, damages, liabilities or judgments, as
well as any other relevant equitable considerations and (ii) in the case of any
Selling Shareholder (x) in such proportion as is appropriate to reflect the
relative benefits received by such Selling Shareholder on the

<PAGE>   19

                                                                             19




one hand and the Underwriters on the other hand from the offering of the Firm
Shares sold by such Selling Shareholder or (y) if the allocation provided by
clause 8(e)(ii)(x) above is not permitted by applicable law, in such proportion
as is appropriate to reflect not only the relative benefits referred to in
clause 8(e)(ii)(x) above but also the relative fault of such Selling
Shareholders on the one hand and the Underwriters on the other hand in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations. The relative benefits received (A) as between the
Company and the Selling Shareholders on the one hand and the Underwriters on
the other hand shall be deemed to be in the same proportion as the total net
proceeds from the offering (after deducting underwriting discounts and
commissions, but before deducting expenses) received by the Selling
Shareholders, and the total underwriting discounts and commissions received by
the Underwriters, bear to the total price to the public of the Shares and (B)
as between each Selling Shareholder on the one hand and the Underwriters on the
other hand shall be deemed to be in the same proportion as the total net
proceeds from the offering (after deducting underwriting discounts and
commissions, but before deducting expenses) received by such Selling
Shareholder bear to the underwriting discounts and commissions received by the
Underwriters in respect of the Firm Shares sold by such Selling Shareholder, in
each case as set forth in the table on the cover page of the Prospectus. The
relative fault (A) as between the Company and the Selling Shareholders on the
one hand and the Underwriters on the other hand 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 relates to information supplied by the Company or the Selling
Shareholders on the one hand or the Underwriters on the other hand and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission and (B) as between each Selling
Shareholder on the one hand and the Underwriters on the other hand 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 relates to information supplied by such Selling
Shareholder on the one hand or the Underwriters on the other hand and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     The Sellers and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 8(e) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an indemnified party as a result of
the losses, claims, damages, liabilities or judgments referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
indemnified party in connection with investigating or defending any matter,
including any action, that could have given rise to such losses, claims,
damages, liabilities or judgments. Notwithstanding the provisions of this
Section 8, no Underwriter shall be required to contribute any amount in excess
of the amount by which the total price at which the Shares underwritten by it
and distributed to the public were offered to the public exceeds the amount of
any damages which such Underwriter has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged

                                                                             20




omission and no Selling Shareholder shall be required to contribute any amount
in excess of the amount by which the total price at which the Firm Shares of
such Selling Shareholders were offered to the public exceeds the amount of any
damages which such Selling Shareholder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission and no Selling Shareholder shall be required to contribute in respect
of any losses, claims, damages, liabilities or judgments (or expenses incurred
in connection therewith) unless the same arise with respect to information
relating to such Selling Shareholder furnished in writing by or on behalf of
the Selling Shareholder for use in the Registration Statement (or any amendment
thereto), the Prospectus (or any amendment or supplement thereto) or any
preliminary prospectus. 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 8(e) are several in proportion to the respective number of Shares
purchased by each of the Underwriters hereunder and not joint.

     (f)  The remedies provided for in this Section 8 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

     (g)  Each Selling Shareholder hereby designates CNA Surety Corporation,
CNA Plaza, Chicago, Illinois 60685, as its authorized agent, upon which process
may be served in any action which may be instituted in any state or federal
court in the State of New York by any Underwriter, any director or officer of
any Underwriter or any person controlling any Underwriter asserting a claim for
indemnification or contribution under or pursuant to this Section 8, and each
Selling Shareholder will accept the jurisdiction of such court in such action,
and waives, to the fullest extent permitted by applicable law, any defense
based upon lack of personal jurisdiction or venue. A copy of any such process
shall be sent or given to such Selling Shareholder, at the address for notices
specified in Section 12 hereof.

     SECTION 9.  Conditions of Underwriters' Obligations.  The several
obligations of the Underwriters to purchase the Firm Shares under this
Agreement are subject to the satisfaction of each of the following conditions:

           (a)  All the representations and warranties of the Company contained
      in this Agreement shall be true and correct on the Closing Date with the
      same force and effect as if made on and as of the Closing Date.

           (b)  If the Company is required to file a Rule 462(b) Registration
      Statement after the effectiveness of this Agreement, such Rule 462(b)
      Registration Statement shall have become effective by 10:00 P.M., New
      York City time, on the date of this Agreement; and no stop order
      suspending the effectiveness of the Registration Statement shall have
      been issued and no proceedings for that purpose shall have been commenced
      or shall be pending before or, to the knowledge of the Company or the
      Underwriters, contemplated by the Commission.

                                                                             21





           (c)  You shall have received on the Closing Date a certificate dated
      the Closing Date, signed by Mark C. Vonnahme, in his capacity as
      President and Chief Executive Officer of the Company, and John S.
      Heneghan, in his capacity as Vice President and Chief Financial Officer
      of the Company, confirming the matters set forth in Sections 6(u), 9(a)
      and 9(b) and that the Company has complied with all of the agreements and
      satisfied all of the conditions herein contained and required to be
      complied with or satisfied by the Company on or prior to the Closing
      Date.

           (d)  Since the respective dates as of which information is given in
      the Prospectus other than as set forth in the Prospectus (exclusive of
      any amendments or supplements thereto subsequent to the date of this
      Agreement), (i) there shall not have occurred any change or any
      development involving a prospective change in the condition, financial or
      otherwise, or the earnings, business, management or operations of the
      Company and its subsidiaries, taken as a whole, (ii) there shall not have
      been any change or any development involving a prospective change in the
      capital stock or in the long-term debt of the Company or any of its
      subsidiaries and (iii) neither the Company nor any of its subsidiaries
      shall have incurred any liability or obligation, direct or contingent,
      the effect of which, in any such case described in clause 9(d)(i),
      9(d)(ii) or 9(d)(iii), in your judgment, is material and adverse and, in
      your judgment, makes it impracticable to market the Shares on the terms
      and in the manner contemplated in the Prospectus.

           (e)  All the representations and warranties of each Selling
      Shareholder contained in this Agreement shall be true and correct on the
      Closing Date with the same force and effect as if made on and as of the
      Closing Date and you shall have received on the Closing Date a
      certificate dated the Closing Date from each Selling Shareholder to such
      effect and to the effect that such Selling Shareholder has complied with
      all of the agreements and satisfied all of the conditions herein
      contained and required to be complied with or satisfied by such Selling
      Shareholder on or prior to the Closing Date.

           (f)  You shall have received on the Closing Date an opinion
      (satisfactory to you and counsel for the Underwriters), dated the Closing
      Date, of Seyfarth, Shaw, Fairweather & Geraldson ("Seyfarth, Shaw"),
      counsel for the Company, to the effect that:

                 (i)   each of the Company and its subsidiaries has been
            incorporated, is validly existing as a corporation in good standing
            under the laws of its jurisdiction of incorporation and has the
            corporate power and authority to carry on its business as described
            in the Prospectus and to own, lease and operate its properties;

                 (ii)  the Firm Shares have been duly authorized and validly
            issued and are fully paid, non-assessable and not subject to any
            preemptive or similar rights;

                 (iii)  the Additional Shares to be issued and sold by the
            Company hereunder have been duly authorized and, if and when issued
            and delivered to the Underwriters against payment therefor as
            provided by this Agreement, will be validly issued, fully paid and
            non-assessable, and the issuance of such Additional Shares will not
            be subject to any preemptive or similar rights;

                 (iv)   all of the outstanding shares of capital stock of each
            of the Company's Insurance Subsidiaries have been duly authorized
            and validly issued and are fully paid and non-assessable, and are
            owned by the Company, directly or indirectly through one or more
            subsidiaries, free and clear of any security interest, claim, lien,
            encumbrance or adverse interest of any nature;

                 (v)  this Agreement has been duly authorized, executed and
            delivered by the Company;

                 (vi)  the authorized capital stock of the Company conforms as
            to legal matters to the description thereof contained in the
            Prospectus under the heading "Description of Capital Stock";

            the Act, no stop order suspending its effectiveness has been issued
            and no proceedings for that purpose are, to the best of such
            counsel's knowledge, pending before or contemplated by the
            Commission;

                 (viii)   the statements under the captions "Description of
            Capital Stock" in the Prospectus and Items 14 and 15 of Part II of
            the Registration Statement, insofar as such statements constitute a
            summary of the legal matters, documents or proceedings referred to
            therein, fairly present the information required with respect to
            such legal matters, documents and proceedings;

                 (ix) the execution, delivery and performance of this Agreement
            by the Company, the compliance by the Company with all the
            provisions hereof and the consummation of the transactions 
            contemplated hereby will not (A) require any consent, approval, 
            authorization or other order of, or qualification with, any court   
            or governmental body or agency (except such as may be required under
            the securities or Blue Sky laws of the various states or under
            applicable state insurance laws if any person acquires an aggregate
            of more than 10% of the outstanding Common Stock pursuant to the
            offering), (B) conflict with or constitute a breach of any of the
            terms or provisions of, or a default under, the charter or by-laws
            of the Company or any of its subsidiaries or conflict with or
            constitute a material breach of any of the terms or provisions of,
            or a default under, any indenture, loan agreement, mortgage, lease
            or other agreement or instrument that has been identified as
            material to the business of the Company and its subsidiaries by an
            officer of the Company to such counsel to which the Company or any
            of its subsidiaries is a party or

            by which the Company or any of its subsidiaries or their respective
            property is bound (other than as to whether any such action would 
            constitute a breach or default with respect to any financial ratios
            or representation or warranty relating to the financial condition of
            the Company or any of its subsidiaries as to which such counsel need
            not express any opinion) or (C) violate or conflict with, in any
            material respect, any applicable U.S. Federal, Illinois or Delaware
            General Corporation law, rule, regulation (other than with respect
            to any state securities or "blue sky" laws or any insurance
            regulatory or administrative matters or tax matters as to which such
            counsel need not express any opinion), or any judgment, order or
            decree of any Illinois court, governmental body or agency having
            jurisdiction over the Company, any of its subsidiaries or their
            respective property;

                 (x)  such counsel does not know of any legal or governmental
            proceedings pending or threatened (other than insurance regulatory
            or administrative proceedings, as to which such counsel need not
            express any opinion) to which the Company or any of its
            subsidiaries is a party or to which any of their respective
            property is subject that are required to be described in the
            Registration Statement or the Prospectus and are not so described,
            or of any statutes, regulations, contracts or other documents that
            are required to be described in the Registration Statement or the
            Prospectus or to be filed as exhibits to the Registration Statement
            that are not so described or filed as required;

                 (xi)  the Company is not and, after giving effect to the
            offering and sale of the Additional Shares and the application of
            the proceeds thereof as described in the Prospectus, will not be,
            an "investment company" as such term is defined in the Investment
            Company Act of 1940, as amended;

                 (xii)  except as set forth on Schedule IV hereto, to the best
            of such counsel's knowledge, there are no contracts, agreements or
            understandings between the Company and any person granting such
            person the right to require the Company to file a registration
            statement under the Act with respect to any securities of the

            come to the attention of such counsel that has caused such counsel
            to believe that the Prospectus, as amended or supplemented, if

      (satisfactory to you and counsel for the Underwriters), dated the Closing
      Date, of Rosenberg & Liebentritt, P.C., counsel for the Selling
      Shareholders, with respect to each of the Selling Shareholders other than

                 (i)  such Selling Stockholder is the record owner of the

            delivery of certificates representing such Shares and payment by 
            the Underwriters of the purchase price therefor

            Shareholder with all the provisions hereof and thereof and the
            consummation of the transactions contemplated hereby and thereby
            will not (A) require any consent, approval, authorization or other
            order of, or qualification with, any court or governmental body or
            agency (except such as may be required under the securities or Blue

an opinion to the effect that:

                 (vii)  assuming that the Underwriters purchase the Shares to
            be delivered by or on behalf of such Selling Shareholder at the

            Underwriters of the purchase price therefor pursuant to the

     This Agreement may be terminated at any time on or prior to the Closing
Date by you by written notice to the Sellers if any of the following has
occurred: (i) any outbreak or escalation of hostilities or other national or
international calamity or crisis or change in economic conditions or in the
financial markets of the United States or elsewhere that, in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market
the Shares on the terms and in the manner contemplated in the Prospectus, (ii)
the suspension or material limitation of trading in securities or other

Chicago Board of Options Exchange, the Chicago Mercantile Exchange, the Chicago

adverse effect on the financial markets in the United States or (vii) A.M. Best
shall have publicly announced that it has under review, with possible negative
implications, its rating of the claims-paying ability of any Insurance
Subsidiary.

     If on the Closing Date or on an Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase the Firm
Shares or Additional Shares, as the case may be, which it has or they have
agreed to purchase hereunder on such date and the aggregate number of Firm
Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not
more than one-tenth of the total number of Firm Shares or Additional Shares, as
the case may be, to be purchased on such date by all Underwriters, each
non-defaulting Underwriter shall be obligated severally, in the proportion
which the number of Firm Shares set forth opposite its name in Schedule I bears
to the total number of Firm Shares which all the non-defaulting Underwriters
have agreed to purchase, or in such other proportion as you may specify, to
purchase the Firm Shares or Additional Shares, as the case may be, which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
on such date; provided that in no event shall the number of Firm Shares or
Additional Shares, as the case may be, which any Underwriter has agreed to
purchase pursuant to Section 2 hereof be increased pursuant to this Section 10

purchase Firm Shares and the aggregate number of Firm Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of
Firm Shares to be purchased by all Underwriters and arrangements satisfactory
to you, the Company and the Selling Shareholders for purchase of such Firm
Shares are not made within 48 hours after such default, this Agreement will
terminate without liability on the part of any non-defaulting Underwriter, the
Company or the Selling Shareholders. In any such case which does not result

in termination of this Agreement, either you or the Sellers shall have the
right to postpone the Closing Date, but in no event for longer than seven days,
in order that the required changes, if any, in the Registration Statement and
the Prospectus or any other documents or arrangements may be effected. If, on
an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Additional Shares and the aggregate number of Additional Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Additional Shares to be purchased on such date, the non-defaulting
Underwriters shall have the option to (i) terminate their obligation hereunder
to purchase such Additional Shares or (ii) purchase not less than the number of
Additional Shares that such non-defaulting Underwriters would have been
obligated to purchase on such date in the absence of such default. Any action
taken under this paragraph shall not relieve any defaulting Underwriter from
liability in respect of any default of any such Underwriter under this
Agreement.

     SECTION 11.  Agreements of the Selling Shareholders.  Each Selling
Shareholder agrees with you and the Company:

     (a)  To pay or to cause to be paid all transfer taxes payable in

Shareholder under this Agreement prior to the Closing Date and to satisfy all
conditions precedent to the delivery of the Firm Shares to be sold by such

the results thereof, made by or on behalf of any Underwriter, the officers or
directors of any Underwriter, any person controlling any Underwriter, the
Company, the officers or directors of the Company, any person controlling the

     If the sale of the Shares provided for herein is not consummated because
of the refusal, inability or failure of any Selling Shareholder to perform its
agreements herein, comply with any provision hereof or satisfy any condition to
the obligations of the Underwriters set forth in Section 9 hereof (in each
case, other than by reason of a default by any of the Underwriters), such
defaulting Selling Shareholder agrees, severally and not jointly, to reimburse
the several Underwriters for all out of pocket expenses (including reasonable
fees and disbursements of counsel) incurred by them as a result of such
refusal, inability or failure.  If the sale of the Shares provided for herein
is not consummated because of the refusal, inability or failure of the Company
to perform its agreements herein, comply with any provision hereof or satisfy
any condition to the obligations of the Underwriters set forth in Section 9
hereof (in each case, other than by reason of a default by any of the
Underwriters), the Company agrees, severally and not jointly, to reimburse the
several Underwriters for all out of pocket expenses (including reasonable fees
and disbursements of counsel) incurred by them as a result of such refusal,
inability or failure. Notwithstanding any termination of this Agreement, the
Company shall be liable for all expenses which it has agreed to pay pursuant to
Section 5(i) hereof.  Each Selling Shareholder also agrees, severally and not
jointly, to reimburse the several Underwriters, their directors and officers
and any persons controlling any of the Underwriters for all out of pocket
expenses (including reasonable fees and disbursements of counsel) incurred by
them in connection with enforcing their rights hereunder against such Selling
Shareholder (including, without limitation, pursuant to Section 8 hereof).  The
Company also agrees to reimburse the several Underwriters, their directors and
officers and any persons controlling any of the Underwriters for all out of

     Except as otherwise provided, this Agreement has been and is made solely
for the benefit of and shall be binding upon the Company, the Selling
Shareholders, the Underwriters, the Underwriters' directors and officers, any
controlling persons referred to herein, the Company's directors and the
Company's officers who sign the Registration Statement and their respective
successors and assigns, all as and to the extent provided in this Agreement,
and no other person shall acquire or have any right under or by virtue of this
Agreement. The term "successors and assigns" shall not include a purchaser of
any of the Shares from any of the several Underwriters merely because of such
purchase.

     This Agreement shall be governed and construed in accordance with the laws
of the State of New York.

     This Agreement may be signed in various counterparts which together shall
constitute one and the same instrument.
