securities in compliance with the provisions of the Investment Company
Stockholders Agreement.

         (d)      Place of Payments with Respect to the Preferred Stock. All
payments to be made to a Purchaser with respect to the Preferred Stock,
including, without limitation, dividends and redemption payments, shall be
delivered to the respective address indicated on Schedule B or to such other
Person or account as a Purchaser may from time to time specify to Invesco by
prior written notice.

         (e)      Consent to Amendments. Except as otherwise expressly provided
herein, the provisions of this Agreement may be amended and Invesco may take any
action herein prohibited, or omit to perform any act herein required to be
performed by it, only if Invesco has obtained the written consent of CHS and
Teachers; provided that in the event that such amendment or waiver would treat a
Purchaser or group of Purchasers materially and adversely differently from any
other Purchaser or group of Purchasers, then such amendment or waiver will
require the consent of such Purchaser or group of Purchasers (based on the
relative ownership of Preferred Stock) so materially and adversely treated. No
other course of dealing between Invesco and any Purchaser or any delay in
exercising any rights hereunder shall operate as a waiver of any rights of any
such Person. For purposes of this Agreement, any Preferred Stock held by Invesco
shall not be deemed to be outstanding.

         (f)      Survival of Representations and Warranties. All
representations and warranties contained herein or made in writing by any party
in connection herewith shall survive the execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby,
regardless of any investigation made by any Purchaser or on such Purchaser's
behalf.

         (g)      Successors and Assigns. Except as otherwise expressly provided
herein, all covenants and agreements contained in this Agreement by or on behalf
of any of the parties hereto shall bind and inure to the benefit of the
respective successors and assigns of the parties hereto whether so expressed or
not. In addition, and whether or not any express assignment has been made, the
provisions of this Agreement which are for each Purchaser's benefit as a

purchaser of the Preferred Stock are also for the benefit of, and enforceable
by, any subsequent holder of the Preferred Stock.

         (h)      Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

         (i)      Counterparts; Facsimile Signature. This Agreement, the
agreements referred to herein, and each other agreement or instrument entered
into in connection herewith or therewith or contemplated hereby or thereby, and
any amendments hereto or thereto, to the extent signed and delivered by means of
a facsimile machine, shall be treated in all manner and respects as an original
agreement or instrument and shall be considered to have the same binding legal
effect as if it were the original signed version thereof delivered in person. At
the request of any party hereto or to any such agreement or instrument, each
other party hereto or thereto shall reexecute original forms thereof and deliver
them to all other parties. No party hereto or to any such agreement or
instrument shall raise the use of a facsimile machine to deliver a signature or
the fact that any signature or agreement or instrument was transmitted or
communicated through the use of a facsimile machine as a defense to the
formation or enforceability of a contract and each such party forever waives any
such defense.

         (j)      Descriptive Headings; Interpretation. The descriptive headings
of this Agreement are inserted for convenience only and do not constitute a part
of this Agreement. The use of the word "including" in this Agreement shall be by
way of example rather than by limitation.

         (k)      Governing Law. This Agreement will be governed in all respects
by the laws of the State of Delaware, without regard to the principles of
conflicts of law of such state.

         (l)      Notices. All notices, demands or other communications to be
given or delivered under or by reason of the provisions of this Agreement shall
be in writing and shall be deemed to have been given when delivered personally
to the recipient, sent to the recipient by reputable express courier service
(charges prepaid) or mailed to the recipient by certified or registered mail,
return receipt requested and postage prepaid.

         (m)      MUTUAL WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN
CONNECTION WITH COMPLEX TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED
BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND
FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT
THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE,
TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF
ARBITRATION, EACH PARTY TO THIS AGREEMENT HEREBY WAIVES ALL RIGHTS TO TRIAL BY
JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE BETWEEN
OR AMONG ANY OF THE PARTIES HERETO, WHETHER ARISING IN CONTRACT, TORT, OR
OTHERWISE, ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS
AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY AND/OR THE RELATIONSHIP
ESTABLISHED AMONG THE PARTIES HEREUNDER.

         (n)      Entire Agreement. This Agreement, those documents expressly
referred to herein and other documents of even date herewith embody the complete
agreement and understanding among the parties and supersede and preempt any
prior understandings, agreements or representations by or among the parties,
written or oral, that may have related to the subject matter hereof in any way.

         (o)      Understanding Among the Purchasers. The determination of each
Purchaser to purchase the Preferred Stock pursuant to this Agreement has been
made by such Purchaser independent of any other Purchaser and independent of any
statements or opinions as to the advisability of such purchase or as to the
properties, business, prospects or condition (financial or otherwise) of Invesco
which may have been made or given by any other Purchaser or by any agent or
employee of any other Purchaser. In addition, it is acknowledged by each of the
Purchasers that no Purchaser has acted as an agent of any other Purchaser in
connection with making its investment hereunder and that no Purchaser shall be
acting as an agent of any other Purchaser in connection with monitoring its
investment hereunder. It is further acknowledged by each of the other Purchasers
that CHS has retained Kirkland & Ellis LLP to act as their counsel in connection
with the transactions contemplated hereby and that Kirkland & Ellis LLP has not
acted as counsel for any of the other Purchasers in connection herewith and that
none of the other Purchasers has the status of a client of Kirkland & Ellis LLP
for conflict of interest or other purposes as a result thereof.
