TO EACH OF THE PURCHASERS LISTED IN
         THE ATTACHED SCHEDULE A:

Ladies and Gentlemen:

                  NUVEEN INVESTMENTS, INC., a Delaware corporation (the
"Company"), agrees with you as follows:

1.       AUTHORIZATION OF NOTES.

                  The Company has authorized the issue and sale of $300,000,000
aggregate principal amount of its 4.22% Senior Notes due September 19, 2008 (the
"Notes", such term to include any such Notes issued in substitution therefor
pursuant to Section 13). The Notes shall be substantially in the form set out in
Exhibit 1, with such changes therefrom, if any, as may be approved by you, the
Other Purchasers and the Company. Certain capitalized terms used in this
Agreement are defined in Schedule B; references to a "Schedule" or an "Exhibit"
are, unless otherwise specified, to a Schedule or an Exhibit attached to this
Agreement. The Notes will be unsecured and will rank pari passu with the
Company's Indebtedness to banks under the Credit Agreements and with all other
senior unsecured Indebtedness of the Company.

2.       SALE AND PURCHASE OF NOTES.

                  Subject to the terms and conditions of this Agreement, the
Company will issue and sell to you and each of the other purchasers named in
Schedule A (the "Other Purchasers"), and you and the Other Purchasers will
purchase from the Company, at the Closing provided for in Section 3, Notes in
the principal amount specified opposite your names in Schedule A at the purchase
price of 100% of the principal amount thereof. Your obligation hereunder and the
obligations of the Other Purchasers are several and not joint obligations and
you shall have no

<PAGE>

obligation and no liability to any Person for the performance or non-performance
by any Other Purchaser hereunder.

3.       CLOSING.

                  The sale and purchase of the Notes to be purchased by you and
the Other Purchasers shall occur at the offices of Gardner Carton & Douglas, 191
North Wacker Drive, Suite 3700, Chicago, Illinois 60606-1698, at 9:00 a.m.,
Chicago time, at a closing (the "Closing") on September 19, 2003 or on such
other Business Day thereafter on or prior to September 30, 2003 as may be agreed
upon by the Company and you and the Other Purchasers. At the Closing the Company
will deliver to you the Notes to be purchased by you in the form of a single
Note (or such greater number of Notes in denominations of at least $100,000 as
you may request) dated the date of the Closing and registered in your name (or
in the name of your nominee), against delivery by you to the Company or its
order of immediately available funds in the amount of the purchase price
therefor by wire transfer of immediately available funds for the account of the
Company to account number 5760674 at Bank One, Chicago, ABA #071000013. If at
the Closing the Company fails to tender such Notes to you as provided above in
this Section 3, or any of the conditions specified in Section 4 shall not have
been fulfilled to your satisfaction, you shall, at your election, be relieved of
all further obligations under this Agreement, without thereby waiving any rights
you may have by reason of such failure or such nonfulfillment.

4.       CONDITIONS TO CLOSING.

                  Your obligation to purchase and pay for the Notes to be sold
to you at the Closing is subject to the fulfillment to your satisfaction, prior
to or at the Closing, of the following conditions:

4.1.     REPRESENTATIONS AND WARRANTIES.

                  The representations and warranties of the Company in this
Agreement shall be correct when made and at the time of the Closing.

4.2.     PERFORMANCE; NO DEFAULT.

                  The Company shall have performed and complied with all
agreements and conditions contained in this Agreement required to be performed
or complied with by it prior to or at the Closing and after giving effect to the
issue and sale of the Notes (and the application of the proceeds thereof as
contemplated by Schedule 5.14) no Default or Event of Default shall have
occurred and be continuing.

4.3.     COMPLIANCE CERTIFICATES.

                  (a)      Officer's Certificate. The Company shall have
         delivered to you an Officer's Certificate, dated the date of the

         authorization, execution and delivery of the Notes and the Agreement.

4.4.     OPINIONS OF COUNSEL.

                  You shall have received opinions in form and substance
satisfactory to you, dated the date of the Closing (a) from Alan G. Berkshire,
General Counsel of the Company, and Winston & Strawn LLP, special counsel for
the Company, covering the matters set forth in Exhibit 4.4(a) and covering such
other matters incident to the transactions contemplated hereby as you or your

deliver such opinion to you) and (b) from Gardner Carton & Douglas LLP, your
special counsel in connection with such transactions, substantially in the form
set forth in Exhibit 4.4(b) and covering such other matters incident to such
transactions as you may reasonably request.

                  On the date of the Closing, your purchase of Notes shall (i)
be permitted by the laws and regulations of each jurisdiction to which you are
subject, without recourse to provisions (such as Section 1405(a)(8) of the New
York Insurance Law) permitting limited investments by insurance companies
without restriction as to the character of the particular investment, (ii) not
violate any applicable law or regulation (including, without limitation,
Regulation U, T or X of the Board of Governors of the Federal Reserve System)
and (iii) not subject you to any tax, penalty or liability under or pursuant to
any applicable law or regulation, which law or regulation was not in effect on
the date hereof. If requested by you, you shall have received an Officer's
Certificate certifying as to such matters of fact as you may reasonably specify
to enable you to determine whether such purchase is so permitted.

4.6.     SALE OF OTHER NOTES.

                  Contemporaneously with the Closing the Company shall sell to
the Other Purchasers and the Other Purchasers shall purchase the Notes to be
purchased by them at the Closing as specified in Schedule A.

4.7.     PAYMENT OF SPECIAL COUNSEL FEES.

National Association of Insurance Commissioners) shall have been obtained by
Gardner Carton & Douglas for the Notes.

4.9.     CHANGES IN CORPORATE STRUCTURE.

                  Except as specified in Schedule 4.9, the Company shall not
have changed its jurisdiction of incorporation or been a party to any merger or
consolidation and shall not have succeeded to all or any substantial part of the
liabilities of any other entity, at any time following the date of the most
recent financial statements referred to in Schedule 5.5.

4.10.    PROCEEDINGS AND DOCUMENTS.

                  All corporate and other proceedings in connection with the
transactions contemplated by this Agreement and all documents and instruments

5.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

                  The Company represents and warrants to you that:

5.1.     ORGANIZATION; POWER AND AUTHORITY.

                  The Company is a corporation duly organized, validly existing
and in good standing under the laws of its jurisdiction of incorporation, and is
duly qualified as a foreign corporation and is in good standing in each
jurisdiction in which such qualification is required by law, other than those
jurisdictions as to which the failure to be so qualified or in good standing
would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. The Company has the corporate power and authority to
own or hold under lease the properties it purports to own or hold under lease,
to transact the business it transacts and proposes to transact, to execute and
deliver this Agreement and the Notes and to perform the provisions hereof and
thereof. The Company possesses all licenses, registrations and authorizations
from and with any Governmental Authority, self-regulatory organization or
securities exchange necessary or material to the conduct of its business as
presently conducted, other than where the failure to possess such licenses,
registrations or authorizations would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

5.2.     AUTHORIZATION, ETC.

                  This Agreement and the Notes have been duly authorized by all
necessary corporate action on the part of the Company, and this Agreement
constitutes, and upon execution and delivery thereof each Note will constitute,
a legal, valid and binding obligation of the Company enforceable against the
Company in accordance with its terms, except as such enforceability may be
limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting the enforcement of creditors' rights generally and
(ii) general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

                                       4

5.3.     DISCLOSURE.

                  The Company, through the Agents, has delivered to you and each
Other Purchaser a copy of a Private Placement Memorandum, dated July 2003 (the
"Memorandum"), relating to the transactions contemplated hereby. Except as
disclosed in Schedule 5.3, this Agreement, the Memorandum, the documents,
certificates or other writings identified in Schedule 5.3 and the financial
statements listed in Schedule 5.5, taken as a whole, do not contain any untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein not misleading in light of the circumstances under

described in Schedule 5.3, or in one of the documents, certificates or other
writings identified therein, or in the financial statements listed in Schedule
5.5, since December 31, 2002, there has been no change in the financial
condition, operations, business or assets of the Company or any Subsidiary,
except changes that individually or in the aggregate would not reasonably be
expected to have a Material Adverse Effect.

5.4.     ORGANIZATION AND OWNERSHIP OF SHARES OF SUBSIDIARIES.

                  (a)      Schedule 5.4 is (except as noted therein) a complete
         and correct list of the Company's Subsidiaries, showing, as to each
         Subsidiary, the correct name thereof, the jurisdiction of its
         organization, and the percentage of shares of each class of its capital
         stock or similar equity interests outstanding owned by the Company and
         each other Subsidiary.

                  (b)      All of the outstanding shares of capital stock or
         similar equity interests of each Subsidiary shown in Schedule 5.4 as
         being owned by the Company and its Subsidiaries have been validly
         issued, are fully paid and nonassessable and are owned by the Company
         or another Subsidiary free and clear of any Lien (except as otherwise
         disclosed in Schedule 5.4).

                  (c)      Each Subsidiary identified in Schedule 5.4 is a
         corporation or other legal entity duly organized, validly existing and
         in good standing under the laws of its jurisdiction of organization,
         and is duly qualified as a foreign corporation or other legal entity
         and is in good standing in each jurisdiction in which such
         qualification is required by law, other than those jurisdictions as to
         which the failure to be so qualified or in good standing would not,
         individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect. Each such Subsidiary has the corporate or
         other power and authority to own or hold under lease the properties it
         purports to own or hold under lease and to transact the business it
         transacts and proposes to transact. Each Subsidiary possesses all
         licenses, registrations and authorizations from and with any
         Governmental Authority, self-regulatory organization or securities
         exchange necessary or material to the conduct of its business as
         presently conducted, other than where the failure to possess such
         licenses, registrations or authorizations would not, individually or in
         the aggregate, reasonably be expected to have a Material Adverse
         Effect.

their operations and cash flows for the respective periods so specified and have

5.6.     COMPLIANCE WITH LAWS, OTHER INSTRUMENTS, ETC.

                  The execution, delivery and performance by the Company of this
Agreement and the Notes will not (i) contravene, result in any breach of, or
constitute a default under, or result in the creation of any Lien in respect of

         actions, suits or proceedings pending or, to the knowledge of the
         Company, threatened against or affecting the Company or any Subsidiary
         or any property of the Company or any Subsidiary in any court or before
         any arbitrator of any kind or before or by any Governmental Authority
         that, individually or in the aggregate, would reasonably be expected to
         have a Material Adverse Effect.

                  (b)      Neither the Company nor any Subsidiary is in default
         under any order, judgment, decree or ruling of any court, arbitrator or
         Governmental Authority or is in violation of any applicable law,
         ordinance, rule or regulation (including Environmental Laws and the USA

5.9.     TAXES.

                  The Company and its Subsidiaries have filed all income tax
returns that are required to have been filed in any jurisdiction, and have paid
all taxes, shown to be due and payable on such returns and all other taxes and
assessments payable by them, to the extent such taxes and assessments have
become due and payable and before they have become delinquent, except for any
tax returns, taxes and assessments (i) the amount of which or penalty for
failure to file is not individually or in the aggregate Material or (ii) the
amount, applicability or validity of which is currently being contested in good
faith by appropriate proceedings and with respect to which the Company or a
Subsidiary, as the case may be, has established adequate reserves in accordance
with GAAP. The federal income tax liabilities of the Company and its
Subsidiaries have been determined by the Internal Revenue Service and paid for
all fiscal years up to and including the fiscal year ended December 31, 1997.

5.10.    TITLE TO PROPERTY; LEASES.

                  The Company and its Subsidiaries have good and sufficient
title to their respective Material properties, including all such properties
reflected in the most recent audited balance sheet referred to in Section 5.5 or
purported to have been acquired by the Company or any Subsidiary after said date
(except as sold or otherwise disposed of in the ordinary course of business), in
each case free and clear of Liens prohibited by this Agreement, except for those
defects in title and Liens that, individually or in the aggregate, would not
have a Material Adverse Effect. All Material leases are valid and subsisting and
are in full force and effect in all material respects.

5.11.    LICENSES, PERMITS, ETC.

                  Except as disclosed in Schedule 5.11, the Company and its
Subsidiaries own or possess all licenses, permits, franchises, authorizations,
patents, copyrights, service marks, trademarks and trade names, or rights
thereto, that are Material, without known conflict with the rights of others,
except for those conflicts that, individually or in the aggregate, would not
have a Material Adverse Effect.

5.12.    COMPLIANCE WITH ERISA.

                  (a)      The Company and each ERISA Affiliate have operated
         and administered each Plan in compliance with all applicable laws
         except for such instances of noncompliance as have not resulted in and
         would not reasonably be expected to result in a Material Adverse
         Effect. Neither the Company nor any ERISA Affiliate has incurred any
         liability pursuant to Title I or IV of ERISA or the penalty or excise
         tax provisions of the Code relating to employee benefit plans (as
         defined in Section 3 of ERISA), and no event, transaction or condition
         has occurred or exists that would reasonably be expected to result in
         the incurrence of any such liability by the Company or any ERISA
         Affiliate, or in the imposition of any Lien on any of the rights,
         properties or assets of the Company or any ERISA Affiliate, in either
         case pursuant to Title I or IV of ERISA or to such penalty or

                                       7
<PAGE>

         excise tax provisions or to Section 401(a)(29) or 412 of the Code,
         other than such liabilities or Liens as would not be individually or in
         the aggregate Material.

                  (b)      The present value of the aggregate benefit
         liabilities under each of the Plans that are subject to the funding
         requirements of Section 412 of the Code (other than Multiemployer
         Plans), determined as of the end of such Plan's most recently ended
         plan year for which an actuarial valuation has been timely performed
         (so as to permit proper compliance with the funding requirements of
         Code Section 412 and the reporting requirements of the Code and ERISA),
         and on the basis of the actuarial assumptions specified for funding
         purposes in such Plan's most recent actuarial valuation report, did not
         exceed the aggregate current value of the assets of such Plan allocable
         to such benefit liabilities by an amount that, individually or in the
         aggregate, is Material. The term "benefit liabilities" has the meaning
         specified in Section 4001 of ERISA and the terms "current value" and
         "present value" have the meaning specified in Section 3 of ERISA.

                  (c)      The Company and its ERISA Affiliates have not
         incurred withdrawal liabilities (and are not subject to contingent
         withdrawal liabilities) under Section 4201 or 4204 of ERISA in respect
         of Multiemployer Plans that individually or in the aggregate are
         Material.

                  (d)      The expected postretirement benefit obligation
         (determined as of the last day of the Company's most recently ended
         fiscal year in accordance with Financial Accounting Standards Board
         Statement No. 106, without regard to liabilities attributable to
         continuation coverage mandated by Section 4980B of the Code) of the
         Company and its Subsidiaries is not Material or has been disclosed in
         the most recent audited consolidated financial statements of the
         Company and its Subsidiaries.

                  (e)      The execution and delivery of this Agreement and the
         issuance and sale of the Notes hereunder will not involve any
         transaction that is subject to the prohibitions of Section 406 of ERISA
         or in connection with which a tax would be imposed pursuant to Section
         4975(c)(1)(A)-(D) of the Code. The representation in the first sentence
         of this Section 5.12(e) is made in reliance upon and subject to the
         accuracy of your representation in Section 6.2 as to the sources of the
         funds used to pay the purchase price of the Notes to be purchased by
         you.

5.13.    PRIVATE OFFERING BY THE COMPANY.

                  Neither the Company nor anyone acting on its behalf has
offered the Notes or any similar securities for sale to, or solicited any offer
to buy any of the same from, or otherwise approached or negotiated in respect
thereof with, any Person other than you, the Other Purchasers and not more than
105 other Institutional Investors, each of which has been offered Notes at a
private sale for investment. Neither the Company nor anyone acting on its behalf
has taken, or will take, any action that would subject the issuance or sale of
the Notes to the registration requirements of Section 5 of the Securities Act.

5.14.    USE OF PROCEEDS; MARGIN REGULATIONS.

                  The Company will apply the proceeds of the sale of the Notes
for general corporate purposes and to repay Indebtedness as set forth in
Schedule 5.14. No part of the proceeds from the sale of the Notes will be used,
directly or indirectly, for the purpose of buying or carrying any margin stock
within the meaning of Regulation U of the Board of Governors of the Federal
Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading
in any securities under such circumstances as to involve the Company in a
violation of Regulation X of said Board (12 CFR 224) or to involve any broker or
dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock
does not constitute more than 5% of the value of the consolidated assets of the
Company and its Subsidiaries, and the Company does not have any present
intention that margin stock will constitute more than 5% of the value of such
assets. As used in this Section, the terms "margin stock" and "purpose of buying
or carrying" shall have the meanings assigned to them in said Regulation U.

5.15.    EXISTING INDEBTEDNESS.

                  Except as described therein, Schedule 5.15 sets forth a
complete and correct list of all outstanding Indebtedness of the Company and its
Subsidiaries as of June 30, 2003, since which date there has been no Material
change in the amounts, interest rates, sinking funds, installment payments or
maturities of the Indebtedness of the Company or its Subsidiaries. Neither the
Company nor any Subsidiary is in default and no waiver of default is currently
in effect, in the payment of any principal or interest on any Indebtedness of
the Company or such Subsidiary and no event or condition exists with respect to
any Indebtedness of the Company or any Subsidiary that is outstanding in an
aggregate principal amount in excess of $10,000,000 and that would permit (or
that with notice or the lapse of time, or both, would permit) one or more
Persons to cause such Indebtedness to become due and payable before its stated
maturity or before its regularly scheduled dates of payment.

5.16.    FOREIGN ASSETS CONTROL REGULATIONS, ETC.

                  Neither the sale of the Notes by the Company hereunder nor its
use of the proceeds thereof will violate (a) the Trading with the Enemy Act, as
amended, (b) any of the foreign assets control regulations of the United States
Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling
legislation or executive order relating thereto, (c) the Anti-Terrorism Order or
(d) the United States Foreign Corrupt Practices Act of 1997, as amended. Without
limiting the foregoing, neither the Company nor any Subsidiary (i) is a blocked
person described in Section 1 of the Anti-Terrorism Order or (ii) engages in any
dealings or transactions, or is otherwise associated, with any such person.

5.17.    STATUS UNDER CERTAIN STATUTES.

                  Neither the Company nor any Subsidiary is an "investment
company" or a company "controlled" by an "investment company" within the meaning
of the Investment Company Act of 1940, as amended, nor are any of them subject
to regulation under the Public

                                       9
<PAGE>

Utility Holding Company Act of 1935, as amended, the Interstate Commerce Act, as
amended by the ICC Termination Act, as amended, or the Federal Power Act, as
amended.

         plan or group of plans maintained by the same employer or employee
         organization beneficially owns more than 10% of all assets allocated to

         plans; or

         to the Company, to visit the principal executive office of the Company,
         to discuss the affairs, finances and accounts of the Company and its
         Subsidiaries with the Company's officers, and, with the consent of the

         affairs, finances, and accounts with their respective officers and
         independent public accountants (and by this provision the Company
         authorizes said accountants to discuss the affairs, finances and
         accounts of the Company and its Subsidiaries), all at such times and as
         often as may be requested.

8.       PREPAYMENT OF THE NOTES.

8.1.     NO SCHEDULED PREPAYMENTS.

                  No regularly scheduled prepayments are due on the Notes prior
to their stated maturity.

8.2.     OPTIONAL PREPAYMENTS WITH MAKE-WHOLE AMOUNT.

                  The Company may, at its option, upon notice as provided below,
prepay at any time all, or from time to time any part of, the Notes in an amount
not less than $5,000,000 in the aggregate in the case of a partial prepayment,
at 100% of the principal amount so prepaid, plus the Make-Whole Amount
determined for the prepayment date with respect to such principal

                                       15
<PAGE>

amount. The Company will give each holder of Notes written notice of each
optional prepayment under this Section 8.2 not less than 30 days and not more
than 60 days prior to the date fixed for such prepayment. Each such notice shall
specify such date, the aggregate principal amount of the Notes to be prepaid on
such date, the principal amount of each Note held by such holder to be prepaid
(determined in accordance with Section 8.3), and the interest to be paid on the
prepayment date with respect to such principal amount being prepaid, and shall
be accompanied by a certificate of a Senior Financial Officer as to the
estimated Make-Whole Amount due in connection with such prepayment (calculated
as if the date of such notice were the date of the prepayment), setting forth
the details of such computation. Two Business Days prior to such prepayment, the
Company shall deliver to each holder of Notes a certificate of a Senior
Financial Officer specifying the calculation of such Make-Whole Amount as of the
specified prepayment date.

8.3.     ALLOCATION OF PARTIAL PREPAYMENTS.

                  In the case of each partial prepayment of the Notes, the
principal amount of the Notes to be prepaid shall be allocated among all of the
Notes at the time outstanding in proportion, as nearly as practicable, to the
respective unpaid principal amounts thereof not theretofore called for
prepayment.

8.4.     MATURITY; SURRENDER, ETC.

                  In the case of each prepayment of Notes pursuant to this
Section 8, the principal amount of each Note to be prepaid shall mature and
become due and payable on the date fixed for such prepayment, together with
interest on such principal amount accrued to such date and the applicable
Make-Whole Amount, if any. From and after such date, unless the Company shall
fail to pay such principal amount when so due and payable, together with the
interest and Make-Whole Amount, if any, as aforesaid, interest on such principal
amount shall cease to accrue. Any Note paid or prepaid in full shall be
surrendered to the Company and canceled and shall not be reissued, and no Note
shall be issued in lieu of any prepaid principal amount of any Note.

8.5.     PURCHASE OF NOTES.

                  The Company will not and will not permit any Affiliate to
purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of
the outstanding Notes except (a) upon the payment or prepayment of the Notes in
accordance with the terms of this Agreement and the Notes or (b) pursuant to an
offer to purchase made by the Company or an Affiliate pro rata to the holders of
all Notes at the time outstanding upon the same terms and conditions. Any such
offer shall provide each holder with sufficient information to enable it to make
an informed decision with respect to such offer, and shall remain open for at
least 20 Business Days. If the holders of more than 25% of the principal amount
of the Notes then outstanding accept such offer, the Company shall promptly
notify the remaining holders of such fact and the expiration date for the
acceptance by holders of Notes of such offer shall be extended by the number of
days necessary to give each such remaining holder at least 10 Business Days from
its receipt of such notice to accept such offer. The Company will promptly
cancel all Notes acquired by it or any Affiliate

                                       16
<PAGE>

pursuant to any payment, prepayment or purchase of Notes pursuant to any
provision of this Agreement and no Notes may be issued in substitution or
exchange for any such Notes.

8.6.     MAKE-WHOLE AMOUNT.

                  The term "MAKE-WHOLE AMOUNT" means, with respect to any Note,
an amount equal to the excess, if any, of the Discounted Value of the Remaining
Scheduled Payments with respect to the Called Principal of such Note over the
amount of such Called Principal, provided that the Make-Whole Amount may in no
event be less than zero. For the purposes of determining the Make-Whole Amount,
the following terms have the following meanings:

                  "CALLED PRINCIPAL" means, with respect to any Note, the
         principal of such Note that is to be prepaid pursuant to Section 8.2 or
         has become or is declared to be immediately due and payable pursuant to
         Section 12.1, as the context requires.

                  "DISCOUNTED VALUE" means, with respect to the Called Principal
         of any Note, the amount obtained by discounting all Remaining Scheduled
         Payments with respect to such Called Principal from their respective
         scheduled due dates to the Settlement Date with respect to such Called
         Principal, in accordance with accepted financial practice and at a
         discount factor (applied on the same periodic basis as that on which
         interest on the Notes is payable) equal to the Reinvestment Yield with
         respect to such Called Principal.

                  "REINVESTMENT YIELD" means, with respect to the Called
         Principal of any Note, .50% over the yield to maturity implied by (i)
         the yields reported, as of 10:00 A.M. (New York City time) on the
         second Business Day preceding the Settlement Date with respect to such
         Called Principal, on the display designated as the "PX1 Screen" on the
         Bloomberg Financial Market Service (or such other display as may
         replace the PX1 Screen on the Bloomberg Financial Market Service) for
         actively traded U.S. Treasury securities having a maturity equal to the
         Remaining Average Life of such Called Principal as of such Settlement
         Date, or (ii) if such yields are not reported as of such time or the
         yields reported as of such time are not ascertainable, the Treasury
         Constant Maturity Series Yields reported, for the latest day for which
         such yields have been so reported as of the second Business Day
         preceding the Settlement Date with respect to such Called Principal, in
         Federal Reserve Statistical Release H.15 (519) (or any comparable
         successor publication) for actively traded U.S. Treasury securities
         having a constant maturity equal to the Remaining Average Life of such
         Called Principal as of such Settlement Date. Such implied yield will be
         determined, if necessary, by (a) converting U.S. Treasury bill
         quotations to bond-equivalent yields in accordance with accepted
         financial practice and (b) interpolating linearly between (1) the
         actively traded U.S. Treasury security with the maturity closest to and
         greater than the Remaining Average Life and (2) the actively traded
         U.S. Treasury security with the maturity closest to and less than the
         Remaining Average Life.

                  "REMAINING AVERAGE LIFE" means, with respect to any Called
         Principal, the number of years (calculated to the nearest one-twelfth
         year) obtained by dividing (i) such

                                       17
<PAGE>

         Called Principal into (ii) the sum of the products obtained by
         multiplying (a) the principal component of each Remaining Scheduled
         Payment with respect to such Called Principal by (b) the number of
         years (calculated to the nearest one-twelfth year) that will elapse
         between the Settlement Date with respect to such Called Principal and
         the scheduled due date of such Remaining Scheduled Payment.

                  "REMAINING SCHEDULED PAYMENTS" means, with respect to the
         Called Principal of any Note, all payments of such Called Principal and
         interest thereon that would be due after the Settlement Date with
         respect to such Called Principal if no payment of such Called Principal
         were made prior to its scheduled due date, provided that if such
         Settlement Date is not a date on which interest payments are due to be
         made under the terms of the Notes, then the amount of the next
         succeeding scheduled interest payment will be reduced by the amount of
         interest accrued to such Settlement Date and required to be paid on
         such Settlement Date pursuant to Section 8.2 or 12.1.

                  "SETTLEMENT DATE" means, with respect to the Called Principal
         of any Note, the date on which such Called Principal is to be prepaid
         pursuant to Section 8.2 or has become or is declared to be immediately
         due and payable pursuant to Section 12.1, as the context requires.

9.       AFFIRMATIVE COVENANTS.

                  The Company covenants that so long as any of the Notes are
outstanding:

9.1.     COMPLIANCE WITH LAW.

                  The Company will, and will cause each of its Subsidiaries to,
comply with all laws, ordinances or governmental rules or regulations to which
each of them is subject, including, without limitation, Environmental Laws, and
will obtain and maintain in effect all licenses, certificates, permits,
franchises and other governmental authorizations necessary to the ownership of
their respective properties or to the conduct of their respective businesses, in
each case to the extent necessary to ensure that non-compliance with such laws,
ordinances or governmental rules or regulations or failures to obtain or
maintain in effect such licenses, certificates, permits, franchises and other
governmental authorizations would not reasonably be expected, individually or in
the aggregate, to have a materially adverse effect on the business, operations,
financial condition or assets of the Company and its Subsidiaries taken as a
whole.

9.2.     INSURANCE.

                  The Company will, and will cause each of its Subsidiaries to,
maintain, with financially sound and reputable insurers, insurance with respect
to their respective properties and businesses against such casualties and
contingencies, of such types, on such terms and in such amounts (including
deductibles, co-insurance and self-insurance, if adequate reserves are
maintained with respect thereto) as is customary in the case of entities of
established reputations engaged in the same or a similar business and similarly
situated.

                                       18
<PAGE>

9.3.     MAINTENANCE OF PROPERTIES.

                  The Company will, and will cause each of its Subsidiaries to,
maintain and keep, or cause to be maintained and kept, their respective
properties in good repair, working order and condition (other than ordinary wear
and tear), so that the business carried on in connection therewith may be
properly conducted at all times, provided that this Section shall not prevent
the Company or any Subsidiary from discontinuing the operation and the
maintenance of any of its properties if such discontinuance is desirable in the
conduct of its business and the Company has concluded that such discontinuance
would not, individually or in the aggregate, have a materially adverse effect on
the business, operations, financial condition or assets of the Company and its
Subsidiaries taken as a whole.

9.4.     PAYMENT OF TAXES.

                  The Company will, and will cause each of its Subsidiaries to,
file all income tax or similar tax returns required to be filed in any
jurisdiction and to pay and discharge all taxes shown to be due and payable on
such returns and all other taxes, assessments, governmental charges, or levies
payable by any of them, to the extent such taxes and assessments have become due
and payable and before they have become delinquent, provided that neither the
Company nor any Subsidiary need file any such return or pay any such tax or
assessment if (i) the amount, applicability or validity thereof is contested by
the Company or such Subsidiary on a timely basis in good faith and in
appropriate proceedings, and the Company or a Subsidiary has established
adequate reserves therefor in accordance with GAAP on the books of the Company
or such Subsidiary or (ii) the nonfiling of all such returns and the nonpayment
of all such taxes and assessments in the aggregate would not reasonably be
expected to have a materially adverse effect on the business, operations,
financial condition or assets of the Company and its Subsidiaries, taken as a
whole.

9.5.     CORPORATE EXISTENCE, ETC.

                  Subject to Sections 10.5 and 10.6, the Company will at all
times preserve and keep in full force and effect its corporate existence.
Subject to Sections 10.5 and 10.6, the Company will at all times preserve and
keep in full force and effect the corporate existence of each of its
Subsidiaries (unless merged into the Company or a Wholly Owned Subsidiary) and
all rights and franchises of the Company and its Subsidiaries unless, in the
good faith judgment of the Company, the termination of or failure to preserve
and keep in full force and effect a particular corporate existence, right or
franchise would not, individually or in the aggregate, have a materially adverse
effect on the business, operations, financial condition or assets of the Company
and its Subsidiaries taken as a whole.

9.6.     NATURE OF BUSINESS.

                  The Company and its Subsidiaries, taken as a whole, will
continue to be engaged primarily in the investment management business or
businesses or activities reasonably related, ancillary or complimentary thereto.

                                       19

9.7.     RANKING OF NOTES.

                  The Notes and the Company's obligations under this Agreement
will rank at least pari passu with all of the Company's outstanding unsecured
senior Indebtedness.

10.      NEGATIVE COVENANTS.

                  The Company covenants that so long as any of the Notes are
outstanding:

10.1.    CONSOLIDATED NET WORTH.

                  The Company will not permit Consolidated Net Worth to be less
than $300,000,000 at any time.

10.2.    CONSOLIDATED DEBT.

                  The Company will not permit the ratio of Consolidated Debt (as

EBITDA (for the Company's then most recently completed four fiscal quarters) to
be greater than 3.0 to 1.0 at any time.

10.3.    LIMITATION ON SUBSIDIARY INDEBTEDNESS.

                  The Company will not at any time permit any Subsidiary,
directly or indirectly, to create, incur, assume, guarantee, have outstanding,
or otherwise become or remain directly or indirectly liable with respect to, any
Indebtedness other than:

                  (a)      Indebtedness outstanding (or available under a
         committed line of credit) on the date hereof and disclosed on Schedule

in a single transaction or series of transactions to any Person except that the
Company may consolidate or merge with any other Person or convey, transfer, sell
or lease all or substantially all of its assets in a single transaction or
series of transactions to any Person, provided that:

                  (a)      the successor formed by such consolidation or the
         survivor of such merger or the Person that acquires by conveyance,

                  (b)      after giving effect to such transaction, no Default

         including (i) sales of securities in the ordinary course of business
         and (ii) sales at fair value of advance sales commissions to a third
         party without recourse to the Company or any of its Subsidiaries in

<PAGE>

                  (c)      Dispositions not otherwise permitted by clauses (a)
         or (b) of this Section 10.6, provided that the aggregate net book value
         of all assets so disposed of in any fiscal year pursuant to this
         Section 10.6(c) does not exceed 15% of Consolidated Total Assets as of
         the end of the immediately preceding fiscal year.

Notwithstanding the foregoing, the Company may, or may permit any Subsidiary to,
make a Disposition and the assets subject to such Disposition shall not be
subject to or included in the foregoing limitation and computation contained in
clause (c) of the preceding sentence to the extent that the net proceeds from
such Disposition are within 365 days of such Disposition (A) reinvested in
assets of a similar nature of at least equivalent value to be used in the
existing business of the Company or such Subsidiary, and/or (B) applied to the
payment or prepayment of the Notes or any other outstanding Indebtedness of the
Company or any Subsidiary ranking pari passu with or senior to the Notes (other
than Indebtedness owing to the Company, any Subsidiary or any Affiliate or in
respect of any revolving credit or similar credit facility providing the Company
or any Subsidiary with the right to obtain loans or other extensions of credit
from time to time, except to the extent that in connection with such payment of
Indebtedness the availability of credit under such credit facility is
permanently reduced by an amount not less than the amount of such proceeds
applied to the payment of such Indebtedness). Any prepayment of Notes pursuant
to this Section 10.6 shall be in accordance with Sections 8.2 and 8.3 without
regard to the minimum prepayment requirements of Section 8.2 if such proceeds
are less than such minimum.

10.7.    TRANSACTIONS WITH AFFILIATES.

                  The Company will not, and will not permit any Subsidiary to,
enter into directly or indirectly any Material transaction or Material group of
related transactions (including the purchase, lease, sale or exchange of
properties of any kind or the rendering of any service) with any Affiliate
(other than the Company or another Subsidiary), except upon fair and reasonable
terms no less favorable to the Company or such Subsidiary than it would obtain
in a comparable arm's-length transaction with a Person not an Affiliate.

12.      REMEDIES ON DEFAULT, ETC.

12.1.    ACCELERATION.

                  (a)      If an Event of Default with respect to the Company
         described in paragraph (g) or (h) of Section 11 (other than an Event of
         Default described in clause (i) of paragraph (g) or described in clause
         (vi) of paragraph (g) by virtue of the fact that such clause
         encompasses clause (i) of paragraph (g)) has occurred, all the Notes
         then outstanding shall automatically become immediately due and
         payable.

                  (b)      If any other Event of Default has occurred and is
         continuing, any holder or holders of a majority in principal amount of
         the Notes at the time outstanding may at any time at its or their
         option, by notice or notices to the Company, declare all the Notes then
         outstanding to be immediately due and payable.

                  (c)      If any Event of Default described in paragraph (a) or
         (b) of Section 11 has occurred and is continuing, any holder or holders
         of Notes at the time outstanding affected by such Event of Default may
         at any time, at its or their option, by notice or notices to the
         Company, declare all the Notes held by it or them to be immediately due
         and payable.

                                       26
<PAGE>

                  Upon any Notes becoming due and payable under this Section
12.1, whether automatically or by declaration, such Notes will forthwith mature
and the entire unpaid principal amount of such Notes, plus (x) all accrued and
unpaid interest thereon and (y) the Make-Whole Amount determined in respect of
such principal amount (to the full extent permitted by applicable law), shall
all be immediately due and payable, in each and every case without presentment,
demand, protest or further notice, all of which are hereby waived. The Company
acknowledges, and the parties hereto agree, that each holder of a Note has the
right to maintain its investment in the Notes free from repayment by the Company
(except as herein specifically provided for) and that the provision for payment
of a Make-Whole Amount by the Company in the event that the Notes are prepaid or
are accelerated as a result of an Event of Default, is intended to provide
compensation for the deprivation of such right under such circumstances.

12.2.    OTHER REMEDIES.

                  If any Default or Event of Default has occurred and is
continuing, and irrespective of whether any Notes have become or have been
declared immediately due and payable under Section 12.1, the holder of any Note
at the time outstanding may proceed to protect and enforce the rights of such
holder by an action at law, suit in equity or other appropriate proceeding,
whether for the specific performance of any agreement contained herein or in any
Note, or for an injunction against a violation of any of the terms hereof or
thereof, or in aid of the exercise of any power granted hereby or thereby or by
law or otherwise.

12.3.    RESCISSION.

                  At any time after any Notes have been declared due and payable
pursuant to clause (b) or (c) of Section 12.1, the holders of not less than a
majority in principal amount of the Notes then outstanding, by written notice to
the Company, may rescind and annul any such declaration and its consequences if
(a) the Company has paid all overdue interest on the Notes, all principal of and
Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid
other than by reason of such declaration, and all interest on such overdue
principal and Make-Whole Amount, if any, and (to the extent permitted by
applicable law) any overdue interest in respect of the Notes, at the Default
Rate, (b) all Events of Default and Defaults, other than non-payment of amounts
that have become due solely by reason of such declaration, have been cured or
have been waived pursuant to Section 17, and (c) no judgment or decree has been
entered for the payment of any monies due pursuant hereto or to the Notes. No
rescission and annulment under this Section 12.3 will extend to or affect any
subsequent Event of Default or Default or impair any right consequent thereon.

12.4.    NO WAIVERS OR ELECTION OF REMEDIES, EXPENSES, ETC.

                  No course of dealing and no delay on the part of any holder of
any Note in exercising any right, power or remedy shall operate as a waiver
thereof or otherwise prejudice such holder's rights, powers or remedies. No
right, power or remedy conferred by this Agreement or by any Note upon any
holder thereof shall be exclusive of any other right, power or remedy referred
to herein or therein or now or hereafter available at law, in equity, by statute
or otherwise. Without limiting the obligations of the Company under Section 15,
the Company will

                                       27

pay to the holder of each Note on demand such further amount as shall be
sufficient to cover all costs and expenses of such holder incurred in any
enforcement or collection under this Section 12, including reasonable attorneys'
fees, expenses and disbursements.

13.      REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES.

13.1.    REGISTRATION OF NOTES.

                  The Company shall keep at its principal executive office a
register for the registration and registration of transfers of Notes. The name
and address of each holder of one or more Notes, each transfer thereof and the
name and address of each transferee of one or more Notes shall be registered in
such register. Prior to due presentment for registration of transfer, the Person
in whose name any Note shall be registered shall be deemed and treated as the
owner and holder thereof for all purposes hereof, and the Company shall not be
affected by any notice or knowledge to the contrary. The Company shall give to
any holder of a Note that is an Institutional Investor, promptly upon request
therefor, a complete and correct copy of the names and addresses of all
registered holders of Notes.

13.2.    TRANSFER AND EXCHANGE OF NOTES.

                  Upon surrender of any Note at the principal executive office
of the Company for registration of transfer or exchange (and in the case of a
surrender for registration of transfer, duly endorsed or accompanied by a
written instrument of transfer duly executed by the registered holder of such
Note or his attorney duly authorized in writing and accompanied by the address
for notices of each transferee of such Note or part thereof), the Company shall
execute and deliver within five Business Days, at the Company's expense (except
as provided below), one or more new Notes (as requested by the holder thereof)
in exchange therefor, in an aggregate principal amount equal to the unpaid
principal amount of the surrendered Note. Each such new Note shall be payable to
such Person as such holder may request and shall be substantially in the form of
Exhibit 1. Each such new Note shall be dated and bear interest from the date to
which interest shall have been paid on the surrendered Note or dated the date of
the surrendered Note if no interest shall have been paid thereon. The Company
may require payment of a sum sufficient to cover any stamp tax or governmental
charge imposed in respect of any such transfer of Notes. Notes shall not be
transferred in denominations of less than $100,000, provided that if necessary
to enable the registration of transfer by a holder of its entire holding of
Notes, one Note may be in a denomination of less than $100,000. Any transferee,
by its acceptance of a Note registered in its name (or the name of its nominee),
shall be deemed to have made the representation set forth in Sections 6.1 and
6.2.

13.3.    REPLACEMENT OF NOTES.

                  Upon receipt by the Company of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of any Note (which evidence shall be, in the case of an Institutional
Investor, notice from such Institutional Investor of such ownership and such
loss, theft, destruction or mutilation), and

                                       28
<PAGE>

                  (a)      in the case of loss, theft or destruction, of
         indemnity reasonably satisfactory to it (provided that if the holder of
         such Note is, or is a nominee for, an original Purchaser or another
         Institutional Investor holder of a Note with a minimum net worth of at
         least $250,000,000, such Person's own unsecured agreement of indemnity
         shall be deemed to be satisfactory), or

                  (b)      in the case of mutilation, upon surrender and
         cancellation thereof,

the Company at its own expense shall execute and deliver within five Business
Days, in lieu thereof, a new Note, dated and bearing interest from the date to
which interest shall have been paid on such lost, stolen, destroyed or mutilated
Note or dated the date of such lost, stolen, destroyed or mutilated Note if no
interest shall have been paid thereon.

14.      PAYMENTS ON NOTES.

14.1.    PLACE OF PAYMENT.

                  Subject to Section 14.2, payments of principal, Make-Whole
Amount, if any, and interest becoming due and payable on the Notes shall be made
in Chicago, Illinois at the principal office of Bank of America, N.A. in such
jurisdiction. The Company may at any time, by notice to each holder of a Note,
change the place of payment of the Notes so long as such place of payment shall
be either the principal office of the Company in such jurisdiction or the
principal office of a bank or trust company in such jurisdiction.

14.2.    HOME OFFICE PAYMENT.

                  So long as you or your nominee shall be the holder of any
Note, and notwithstanding anything contained in Section 14.1 or in such Note to
the contrary, the Company will pay all sums becoming due on such Note for
principal, Make-Whole Amount, if any, and interest by the method and at the
address specified for such purpose below your name in Schedule A, or by such
other method or at such other address as you shall have from time to time
specified to the Company in writing for such purpose, without the presentation
or surrender of such Note or the making of any notation thereon, except that
upon written request of the Company made concurrently with or reasonably
promptly after payment or prepayment in full of any Note, you shall surrender
such Note for cancellation, reasonably promptly after any such request, to the
Company at its principal executive office or at the place of payment most
recently designated by the Company pursuant to Section 14.1. Prior to any sale
or other disposition of any Note held by you or your nominee you will, at your
election, either endorse thereon the amount of principal paid thereon and the
last date to which interest has been paid thereon or surrender such Note to the
Company in exchange for a new Note or Notes pursuant to Section 13.2. The
Company will afford the benefits of this Section 14.2 to any Institutional
Investor that is the direct or indirect transferee of any Note purchased by you
under this Agreement and that has made the same agreement relating to such Note
as you have made in this Section 14.2.

                                       29

15.      EXPENSES, ETC.

15.1.    TRANSACTION EXPENSES.

                  Whether or not the transactions contemplated hereby are
consummated, the Company will pay all reasonable costs and expenses (including
reasonable attorneys' fees of your special counsel and, if reasonably required,
local or other counsel) incurred by you and each Other Purchaser or holder of a
Note in connection with such transactions and in connection with any amendments,
waivers or consents under or in respect of this Agreement or the Notes (whether

costs and expenses incurred in enforcing or defending (or determining whether or
how to enforce or defend) any rights under this Agreement or the Notes, or in

all related documents and financial information, and all subsequent annual and

authority thereof. The Company will pay, and will save you and each other holder
of a Note harmless from, all claims in respect of any fees, costs or expenses if
any, of brokers and finders (other than those retained by you).

15.2.    SURVIVAL.

                  The obligations of the Company under this Section 15 will
survive the payment or transfer of any Note, the enforcement, amendment or
waiver of any provision of this Agreement or the Notes, and the termination of
this Agreement.

16.      SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

                  All representations and warranties contained herein shall
survive the execution and delivery of this Agreement and the Notes, the purchase
or transfer by you of any Note or portion thereof or interest therein and the
payment of any Note, and may be relied upon by any subsequent holder of a Note,
regardless of any investigation made at any time by or on behalf of you or any
other holder of a Note. All statements contained in any certificate or other
instrument delivered by or on behalf of the Company pursuant to this Agreement
shall be deemed representations and warranties of the Company under this
Agreement. Subject to the preceding sentence, this Agreement and the Notes
embody the entire agreement and understanding between you and the Company and
supersede all prior agreements and understandings relating to the subject matter
hereof.

                                       30

17.      AMENDMENT AND WAIVER.

17.1.    REQUIREMENTS.

                  This Agreement and the Notes may be amended, and the
observance of any term hereof or of the Notes may be waived (either
retroactively or prospectively), with (and only with) the written consent of the
Company and the Required Holders, except that (a) no amendment or waiver of any
of the provisions of Section 1, 2, 3, 4, 5, 6 or 21 hereof, or any defined term
(as it is used therein), will be effective as to you unless consented to by you
in writing, and (b) no such amendment or waiver may, without the written consent
of the holder of each Note at the time outstanding affected thereby, (i) subject
to the provisions of Section 12 relating to acceleration or rescission, change
the amount or time of any prepayment or payment of principal of, or reduce the
rate or change the time of payment or method of computation of interest or of
the Make-Whole Amount on, the Notes, (ii) change the percentage of the principal
amount of the Notes the holders of which are required to consent to any such
amendment or waiver, or (iii) amend any of Sections 8, 11(a), 11(b), 12, 17 or
20.

17.2.    SOLICITATION OF HOLDERS OF NOTES.

                  (a)      Solicitation. The Company will provide each holder of
         the Notes (irrespective of the amount of Notes then owned by it) with
         sufficient information, sufficiently far in advance of the date a
         decision is required, to enable such holder to make an informed and
         considered decision with respect to any proposed amendment, waiver or
         consent in respect of any of the provisions hereof or of the Notes. The
         Company will deliver executed or true and correct copies of each
         amendment, waiver or consent effected pursuant to the provisions of
         this Section 17 to each holder of outstanding Notes promptly following
         the date on which it is executed and delivered by, or receives the
         consent or approval of, the requisite holders of Notes.

                  (b)      Payment. The Company will not directly or indirectly
         pay or cause to be paid any remuneration, whether by way of
         supplemental or additional interest, fee or otherwise, or grant any
         security, to any holder of Notes as consideration for or as an
         inducement to the entering into by any holder of Notes or any waiver or
         amendment of any of the terms and provisions hereof unless such
         remuneration is concurrently paid, or security is concurrently granted,
         on the same terms, ratably to each holder of Notes then outstanding,
         even if such holder did not consent to such waiver or amendment.

                  (c)      Consent in Contemplation of Transfer. Any consent
         made pursuant to this Section 17 by a holder of Notes that has
         transferred or has agreed to transfer its Notes to the Company, any
         Subsidiary or any Affiliate of the Company and has provided or has
         agreed to provide such written consent as a condition to such transfer
         shall be void and of no force or effect except solely as to such
         holder, and any amendments effected or waivers granted or to be
         effected or granted that would not have been or would not be so
         effected or granted but for such consent (and the consents of other
         holders of Notes that were acquired under the same or similar
         conditions) shall be void and of no force or effect except solely as to
         such holder.

                                       31
<PAGE>

17.3.    BINDING EFFECT, ETC.

                  Any amendment or waiver consented to as provided in this
Section 17 applies equally to all holders of Notes and is binding upon them and
upon each future holder of any Note and upon the Company without regard to
whether such Note has been marked to indicate such amendment or waiver. No such
amendment or waiver will extend to or affect any obligation, covenant,
agreement, Default or Event of Default not expressly amended or waived or impair
any right consequent thereon. No course of dealing between the Company and the
holder of any Note nor any delay in exercising any rights hereunder or under any
Note shall operate as a waiver of any rights of any holder of such Note. As used
herein, the term "this Agreement" or "the Agreement" and references thereto
shall mean this Agreement as it may from time to time be amended or
supplemented.

17.4.    NOTES HELD BY COMPANY, ETC.

                  Solely for the purpose of determining whether the holders of
the requisite percentage of the aggregate principal amount of Notes then
outstanding approved or consented to any amendment, waiver or consent to be
given under this Agreement or the Notes, or have directed the taking of any
action provided herein or in the Notes to be taken upon the direction of the
holders of a specified percentage of the aggregate principal amount of Notes
then outstanding, Notes directly or indirectly owned by the Company or any of
its Affiliates shall be deemed not to be outstanding.

18.      NOTICES.

                  All notices and communications provided for hereunder shall be
in writing and sent (a) by telecopy if the sender on the same day sends a
confirming copy of such notice by a recognized overnight delivery service
(charges prepaid), or (b) by registered or certified mail with return receipt
requested (postage prepaid), or (c) by a recognized overnight delivery service

                           (i)      if to you or your nominee, to you or it at

                  the Company in writing,

                           (ii)     if to any other holder of any Note, to such
                  holder at such address as such other holder shall have
                  specified to the Company in writing, or

                           (iii)    if to the Company, to the Company at its
                  address set forth at the beginning hereof to the attention of
                  the Treasurer with a copy to the attention of the General
                  Counsel, or at such other address as the Company shall have
                  specified to the holder of each Note in writing.

19.      REPRODUCTION OF DOCUMENTS.

                  This Agreement and all documents relating thereto, including
(a) consents, waivers and modifications that may hereafter be executed, (b)
documents received by you at the Closing (except the Notes themselves), and (c)
financial statements, certificates and other information previously or hereafter
furnished to you, may be reproduced by you at your sole cost and expense by any
photographic, photostatic, microfilm, microcard, miniature photographic or other
similar process and you may destroy any original document so reproduced. The
Company agrees and stipulates that, to the extent permitted by applicable law,
any such reproduction shall be admissible in evidence as the original itself in
any judicial or administrative proceeding (whether or not the original is in
existence and whether or not such reproduction was made by you in the regular
course of business) and any enlargement, facsimile or further reproduction of
such reproduction shall likewise be admissible in evidence. This Section 19
shall not prohibit the Company or any other holder of Notes from contesting any
such reproduction to the same extent that it could contest the original, or from
introducing evidence to demonstrate the inaccuracy of any such reproduction.

20.      CONFIDENTIAL INFORMATION.

                  For the purposes of this Section 20, "Confidential
Information" means information delivered to you by or on behalf of the Company
or any Subsidiary in connection with the transactions contemplated by or
otherwise pursuant to this Agreement that is proprietary or confidential in
nature and that was clearly marked or labeled or otherwise adequately identified
when received by you as being confidential information of the Company or such
Subsidiary, provided that such term does not include information that (a) was
publicly known or otherwise known to you prior to the time of such disclosure,
(b) subsequently becomes publicly known through no act or omission by you or any
Person acting on your behalf, (c) otherwise becomes known to you other than
through disclosure by the Company or any Subsidiary, or (d) constitutes
financial statements delivered to you under Section 7.1 that are otherwise
publicly available. You will maintain the confidentiality of such Confidential
Information in accordance with procedures adopted by you in good faith to
protect confidential information of third parties delivered to you, provided
that you may deliver or disclose Confidential Information to (i) your directors,
trustees, officers, employees, agents, attorneys and Affiliates (to the extent
such disclosure reasonably relates to the administration of the investment
represented by your Notes), (ii) your financial advisors and other professional
advisors who agree to hold confidential the Confidential Information
substantially in accordance with the terms of this Section 20, (iii) any other
holder of any Note, (iv) any Institutional Investor to which you sell or offer
to sell such Note or any part thereof or any participation therein (if such
Person has agreed in writing prior to its receipt of such Confidential
Information to be bound by the provisions of this Section 20), (v) any Person
from which you offer to purchase any security of the Company (if such Person has
agreed in writing prior to its receipt of such Confidential Information to be
bound by the provisions of this Section 20), (vi) any federal or state
regulatory authority having jurisdiction over you, (vii) the National
Association of Insurance Commissioners or any similar organization, or any
nationally recognized rating agency that requires access to information about
your investment portfolio or (viii) any other Person to which such delivery or
disclosure may be necessary or appropriate (w) to effect compliance with any
law, rule, regulation or order

                                       33
<PAGE>

applicable to you, (x) in response to any subpoena or other legal process, (y)
in connection with any litigation to which you are a party or (z) if an Event of
Default has occurred and is continuing, to the extent you may reasonably
determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of the rights and remedies under your Notes
and this Agreement. Each holder of a Note, by its acceptance of a Note, will be
deemed to have agreed to be bound by and to be entitled to the benefits of this
Section 20 as though it were a party to this Agreement. On reasonable request by
the Company in connection with the delivery to any holder of a Note of
information required to be delivered to such holder under this Agreement or
requested by such holder (other than a holder that is a party to this Agreement
or its nominee), such holder will enter into an agreement with the Company
embodying the provisions of this Section 20.

                  Notwithstanding anything to the contrary set forth herein or
in any other written or oral understanding or agreement to which the parties
hereto are parties or by which they are bound, the parties acknowledge and agree
that (i) any obligations of confidentiality contained herein and therein do not
apply and have not applied from the commencement of discussions between the
parties to the tax treatment and tax structure of the Notes (and any related
transactions or arrangements), and (ii) each party (and each of its employees,
representatives, or other agents) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the Notes and all
materials of any kind (including opinions or other tax analyses) that are
provided to such party relating to such tax treatment and tax structure, all
within the meaning of Treasury Regulations Section 1.6011-4.

21.      SUBSTITUTION OF PURCHASER.

                  You shall have the right to substitute any one of your
Affiliates as the purchaser of the Notes that you have agreed to purchase
hereunder, by written notice to the Company, which notice shall be signed by
both you and such Affiliate, shall contain such Affiliate's agreement to be
bound by this Agreement and shall contain a confirmation by such Affiliate of
the accuracy with respect to it of the representations set forth in Section 6.
Upon receipt of such notice, wherever the word "you" is used in this Agreement
(other than in this Section 21), such word shall be deemed to refer to such
Affiliate in lieu of you. In the event that such Affiliate is so substituted as
a purchaser hereunder and such Affiliate thereafter transfers to you all of the
Notes then held by such Affiliate, upon receipt by the Company of notice of such
transfer, wherever the word "you" is used in this Agreement (other than in this
Section 21), such word shall no longer be deemed to refer to such Affiliate, but
shall refer to you, and you shall have all the rights of an original holder of
the Notes under this Agreement.

22.      MISCELLANEOUS.

22.1.    SUCCESSORS AND ASSIGNS.

                  All covenants and other agreements contained in this Agreement
by or on behalf of any of the parties hereto bind and inure to the benefit of
their respective successors and assigns (including any subsequent holder of a
Note) whether so expressed or not.

                                       34
<PAGE>

22.2.    PAYMENTS DUE ON NON-BUSINESS DAYS.

                  Anything in this Agreement or the Notes to the contrary
notwithstanding, any payment of principal of or Make-Whole Amount or interest on
any Note that is due on a date other than a Business Day shall be made on the
next succeeding Business Day without including the additional days elapsed in
the computation of the interest payable on such next succeeding Business Day.

22.3.    SEVERABILITY.

                  Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or
render unenforceable such provision in any other jurisdiction.

22.4.    CONSTRUCTION.

                  Each covenant contained herein shall be construed (absent
express provision to the contrary) as being independent of each other covenant
contained herein, so that compliance with any one covenant shall not (absent
such an express contrary provision) be deemed to excuse compliance with any
other covenant. Where any provision herein refers to action to be taken by any
Person, or which such Person is prohibited from taking, such provision shall be
applicable whether such action is taken directly or indirectly by such Person.

22.5.    COUNTERPARTS.

                  This Agreement may be executed in any number of counterparts,
each of which shall be an original but all of which together shall constitute
one instrument. Each counterpart may consist of a number of copies hereof, each
signed by less than all, but together signed by all, of the parties hereto.

22.6.    JURISDICTION; WAIVER OF JURY TRIAL.

                  The Company irrevocably submits to the non-exclusive in
personam jurisdiction of any New York State or federal court sitting in the
Borough of Manhattan, The City of New York, over any suit, action or proceeding
arising out of or relating to this Agreement or the Notes. To the fullest extent
permitted by applicable law, the Company irrevocably waives and agrees not to
assert, by way of motion, as a defense or otherwise, any claim that it is not
subject to the in personam jurisdiction of any such court, any objection that it
may now or hereafter have to the laying of the venue of any such suit, action or
proceeding brought in any such court and any claim that any such suit, action or
proceeding brought in any such court has been brought in an inconvenient forum.

22.7.    GOVERNING LAW.

                  THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE
WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE LAW OF THE STATE
OF NEW YORK, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAW.
