            (a)   Pursuant to the terms of this Agreement (including the
restrictions included in this Section 4 and in Section 7 hereof), and subject to
the continuing and exclusive authority of the Directors over the management of
the Company, the Directors hereby delegate to the Advisor the authority to: (1)
locate, analyze and select investment opportunities; (2) structure the terms and
conditions of transactions pursuant to which investments will be made or
acquired for the

                                      -10-
<PAGE>   11

            (b)   Notwithstanding the foregoing, any investment in Property,
including any acquisition of any Property by the Company (as well as any
financing acquired by the Company in connection with such acquisition), will
require the prior approval of the Directors unless, prior to completion of any
such transaction, the Advisor provides the Company with:

                  (i)   an appraisal for the Property indicating that the Total
      Property Cost of the Property does not exceed the Appraised Value of the
      Property; and

                  (ii)  a representation from the Advisor that the Property, in
      conjunction with the Company's other investments and proposed investments,
      at the time the Company is committed to purchase the Property, is
      reasonably expected to fulfill the Company's investment objectives and
      policies as established by the Directors and then in effect.

            (c)   If a transaction requires approval by the Independent
Directors, the Advisor will deliver to the Independent Directors all documents
required by them to properly evaluate the proposed investment in such Property
or such Loan.

      Notwithstanding the foregoing, the prior approval of the Directors,
including a majority of the Independent Directors, will be required for
transactions involving: (a) investments in Properties in respect of which all of
the requirements specified in Section 4(b) hereof have not be satisfied; (b)
investments in Properties made through joint venture arrangements with
Affiliates of the Advisor; (c) investments in Properties which are not
contemplated by the terms of the Prospectus; (d) transactions that present
issues which involve conflicts of interest for the Advisor (other than conflicts
involving the payment of fees or the reimbursement of expenses); and (e) the
lease of assets to the Sponsor, any Director or the Advisor.

      The Directors may, at any time upon the giving of notice to the Advisor,
modify or revoke the authority set forth in this Section 4. If and to the extent
the Directors so modify or revoke the authority contained herein, the Advisor
shall henceforth submit to the Directors for prior approval such proposed
transactions involving investments in Property as thereafter require prior
approval, provided however, that such modification or revocation shall be
effective upon receipt by the Advisor and shall not be applicable to investment
transactions to which the Advisor has committed the Company prior to the date of
receipt by the Advisor of such notification.

      5.    BANK ACCOUNTS. The Advisor may establish and maintain one or more
bank accounts in its own name for the account of the Company or in the name of
the Company and may collect and deposit into any such account or accounts, and
disburse from any such account or accounts, any money on behalf of the Company,
provided that no funds shall be commingled

                                      -11-
<PAGE>   12
with the funds of the Advisor; and the Advisor shall from time to time render
appropriate accountings of such collections and payments to the Directors and to
the auditors of the Company.

      6.    RECORDS; ACCESS. The Advisor shall maintain appropriate records of
all its activities hereunder and make such records available for inspection by
the Directors and by counsel, auditors and authorized agents of the Company, at
any time or from time to time during normal business hours. The Advisor shall at
all reasonable times have access to the books and records of the Company.

      7.    LIMITATIONS ON ACTIVITIES. Anything else in this Agreement to the
contrary notwithstanding, the Advisor shall refrain from taking any action
which, in its sole judgment made in good faith, would adversely affect the
status of the Company as a REIT, subject the Company to regulation under the
Investment Company Act of 1940, would violate any law, rule, regulation or
statement of policy of any governmental body or agency having jurisdiction over
the Company, its Shares or its Securities, or otherwise not be permitted by the
Articles of Incorporation or Bylaws, except if such action shall be ordered by
the Directors, in which case the Advisor shall notify promptly the Directors of
the Advisor's judgment of the potential impact of such action and shall refrain
from taking such action until it receives further clarification or instructions
from the Directors. In such event the Advisor shall have no liability for acting
in accordance with the specific instructions of the Directors so given.
Notwithstanding the foregoing, the Advisor, its partners and employees, and
partners, stockholders, directors and officers of the Advisor's partners shall
not be liable to the Company, or to the Directors or Shareholders for any act or
omission by the Advisor, its partners or employees, or partners, stockholders,
directors or officers of the Advisor's partners except as provided in Sections
20 and 22 hereof.

      8.    RELATIONSHIP WITH DIRECTORS. Partners and employees of the Advisor
or partners in the Advisor or any corporate parents of a partner, or directors,
officers or stockholders of any partner or corporate parent of a partner may
serve as a Director and as officers of the Company, except that no partner in or
employee of the Advisor or its Affiliates who also is a Director or officer of
the Company shall receive any compensation from the Company for serving as a
Director or officer other than for reasonable reimbursement for travel and
related expenses incurred in attending meetings of the Directors.

      9.    FEES.

            (a)   ASSET MANAGEMENT FEE. The Company shall pay to the Advisor as
compensation for the advisory services rendered to the Company hereunder an
amount equal to one half of one percent per annum of the Average Invested Assets
of the Company (the "Asset Management Fee") calculated as set forth below. The
Asset Management Fee will be calculated monthly, beginning with the month in
which the Company first makes an investment in Properties or Loans, on the basis
of one-twelfth of one half of one percent of the Average Invested Assets for the
preceding month, computed as a daily average. The Asset Management Fee
calculated with respect to each month shall be payable monthly on the last day
of such month, or the first business day following the last day of such month.
If at the end of any fiscal quarter, the Company's Operating Expenses exceed the
2%/25% Guidelines over the immediately preceding 12 months, payment of the Asset
Management Fee will be withheld to

                                      -12-
<PAGE>   13
the extent necessary to cause the Company to satisfy the 2%/25% Guidelines. Any
portion of the Asset Management Fee not paid due to the Company's failure to
satisfy the 2%/25% Guidelines shall be paid at the end of the next fiscal
quarter to the extent such payment would not cause the Company to fail to
satisfy the 2%/25% Guidelines if such payment were to be included in the
Company's Operating Expenses for the 12 months preceding such payment. For
purposes of determining the amount of the Asset Management Fee, the Average
Invested Assets will be, in any particular month, (i) for all months during the
period from inception of the Company through December 31, 2004, the average of
the aggregate book value of the assets of the Company invested, directly or
indirectly, in equity interests, in Properties and in Loans secured by real
estate, before reserves for depreciation or bad debts or other similar non-cash
reserves, all as shown on the books of the Company on each day of such month and
(ii) for all months beginning after December 31, 2004, the estimated value of
all of the Properties determined in accordance with the most recently conducted
Valuation, plus the principal balance of all Loans. Any part of the Asset
Management Fee that has been subordinated pursuant to this subsection (a) shall
not be deemed earned until such time as payable hereunder.

            (b)   PERFORMANCE FEE. In addition to the Asset Management Fee
described in Section 9(a) above, the Company shall also pay to the Advisor as
compensation for the advisory services rendered to the Company hereunder an
amount equal to one half of one percent per annum of the Average Invested Assets
of the Company (the "Performance Fee") calculated as set forth below. The
Performance Fee will be calculated monthly, beginning with the month in which
the Company first makes an investment in Properties or Loans, on the basis of
one-twelfth of one half of one percent of the Average Invested Assets during the
previous month, computed as a daily average. The Performance Fee calculated with
respect to each month shall be payable on a quarterly basis on the last day of
the first month of the immediately following fiscal quarter. Payment of this fee
for any quarter will be subordinated to the preferred return of six percent. Any
portion of the Performance Fee not paid due to the Company's failure to pay the
Preferred Return shall be paid by the Company, to the extent it is not
restricted by the 2%/25% Guidelines as described below, at the end of the next
fiscal quarter through which the Company has paid the Preferred Return. If at
the end of any fiscal quarter, the Company's Operating Expenses exceed the
2%/25% Guidelines over the immediately preceding 12 months, payment of the
Performance Fee will be withheld to the extent necessary to cause the Company to
satisfy the 2%/25% Guidelines. Any portion of the Performance Fee not paid due
to the Company's failure to satisfy the 2%/25% Guidelines shall be paid at the
end of the next fiscal quarter to the extent such payment would not cause the
Company to fail to satisfy the 2%/25% Guidelines if such payment were to be
included in the Company's Operating Expenses for the 12 months preceding such
payment. For purposes of determining the amount of the Performance Fee, the
Average Invested Assets will be, in any particular month, (i) for all months
during the period from inception of the Company through December 31, 2004, the
average of the aggregate book value of the assets of the Company invested,
directly or indirectly, in equity interests, in Properties and in Loans secured
by real estate, before reserves for depreciation or bad debts or other similar
non-cash reserves, all as shown on the books of the Company on each day of such
month and (ii) for all months beginning after December 31, 2004, the estimated
value of all of the Company's Properties determined in accordance with the most
recently conducted Valuation, plus the principal balance of all Loans. Any part
of the Performance Fee that has been subordinated pursuant to this subsection
(b) shall not be deemed earned until such time as payable hereunder.

            (c)   ACQUISITION FEE. The Advisor may receive as compensation for
services rendered in connection with the investigation, selection and
acquisition (by purchase, investment or exchange) of Property an Acquisition Fee
payable by the seller of such Property or the Company. The total Acquisition
Fees (not including Subordinated Acquisition Fees) payable to the Advisor and
its Affiliates plus Acquisition Fees (not including Subordinated Acquisition
Fees) payable by the Company to any other party may not exceed two-and-a-half
percent of the aggregate Total Property Cost of all Properties purchased by the
Company with proceeds from the Offering (calculated after all such proceeds are
invested) unless a majority of the Directors (including a majority of the
Independent Directors) not otherwise interested in any transaction approve the
excess as being commercially competitive, fair and reasonable to the Company.
The total amount of Acquisition Fees (including Subordinated Acquisition Fees)
and Acquisition Expenses paid by the Company may not exceed six percent of the
aggregate Contract Purchase Price of all Properties purchased by the Company
unless a majority of the Board (including a majority of the Independent
Directors) not otherwise interested in any transaction approves fees in excess
of this limit as being commercially competitive, fair and reasonable to the
Company.

            (d)   SUBORDINATED ACQUISITION FEE. In addition to the Acquisition
Fee described in Section 9(c) above, the Advisor may receive as additional
compensation for services rendered in connection with the investigation,
selection and acquisition (by purchase, investment or exchange) of a Property a
Subordinated Acquisition Fee payable by the seller of such Property or the
Company. The total Subordinated Acquisition Fees payable to the Advisor and its
Affiliates plus Subordinated Acquisition Fees payable by the Company to any
other party may not exceed two percent of the aggregate Total Property Cost of
all Properties purchased by the Company with proceeds from the Offering
(calculated after all such proceeds are invested) unless a majority of the
Directors (including a majority of the Independent Directors) not otherwise
interested in any transaction approve the excess as being commercially
competitive, fair and reasonable to the Company. The unpaid portion of the
Subordinated Acquisition Fee with respect to any Property shall bear interest at
the rate of six percent per annum from the date of acquisition of such Property
until such portion is paid. Subject to the following sentence, the Subordinated
Acquisition Fee with respect to any Property shall be payable in equal annual
installments on January 1 of each of the four calendar years following the first
anniversary of the date such Property was purchased. Accrued interest or all
unpaid Subordinated Acquisition Fees shall also be payable on such dates. The
portion of the Subordinated Acquisitions Fees, and accrued interest thereon,
otherwise payable for any year on January 1 of the following year shall be
payable only if the Shareholders have received a Preferred Return. Any portion
of the Subordinated Acquisitions Fees, and accrued interest thereon, not paid
due to the Company's failure to pay the Preferred Return for the most recently
completed fiscal year shall be paid by the Company on January 1 following the
fiscal year through which the Company has paid the Preferred Return. In the
event that the Shares are listed for trading on a national securities exchange
or are included for quotation on Nasdaq, all Subordinated Acquisition Fees, and
accrued interest thereon, shall be due and payable on the date of such listing
or inclusion.

            (e)   LOAN REFINANCING FEE. The Company shall pay to the Advisor for
all qualifying loan refinancings of Properties a Loan Refinancing Fee in the
amount of one percent of the principal amount of any loan secured by a Property.
Any Loan Refinancing Fee shall be due and payable upon the funding of the
related mortgage loan or as soon thereafter as is

                                      -14-
<PAGE>   15

reasonably practicable. A refinancing will qualify for a Loan Refinancing Fee
only if: the terms of the new loan represent an improvement over the terms of
the refinanced loan, the new loan materially increases the total debt secured by
a particular Property or the maturity date of the refinanced loan (which must
have a term of five years or more) is less than one year from the date of the
refinancing.

            (f)   PROPERTY MANAGEMENT FEE. The Advisor may cause the Company to
pay Property Management Fees for property management services rendered by the
Advisor or its Affiliates in connection with Properties acquired directly or
through foreclosure. The Advisor or an Affiliate will provide property
management services only if a Property becomes vacant or requires more active
management than contemplated at the time such Property is acquired. In either
event, the Company, by approval of the Directors (including a majority of the
Independent Directors), may engage the Advisor or an Affiliate, subject to such
Advisor's or such Affiliate's qualifying as an "independent contractor" pursuant
to Section 856(d)(3) of the Code, to provide property management services. If
such services are rendered by the Advisor or an Affiliate, the maximum Property
Management Fees which may be paid to the Advisor or an Affiliate will be six
percent of gross revenues from commercial Properties and five percent of gross
revenues from residential Properties, plus reimbursed expenses, paid monthly,
where such entity performs property management and leasing, re-leasing and
leasing related services, or three percent of the gross revenues of the Property
if only property management services are performed by such entity. Property
Management Fees payable to the Advisor or an Affiliate for an industrial or
commercial Property leased on a long-term (defined as at least ten years,
excluding renewals) triple net basis, may not exceed one percent of the gross
revenues from such Property, except for a one-time initial leasing fee equal to
three percent of total base rents payable for the first five years of the lease,
payable in five equal annual installments. Such fees to the Advisor or its
Affiliate cannot exceed the usual and customary amounts charged for similar
services in the same geographic area.

            (g)   SUBORDINATED DISPOSITION FEE. If the Advisor or an Affiliate
provides a substantial amount of the services (as determined by a majority of
the Independent Directors) in the sale of a Property, the Advisor or an
Affiliate shall receive a Subordinated Disposition Fee equal to the lesser of:
(i) 50% of the Competitive Real Estate Commission and (ii) three percent of the
Contract Sales Price of such Property. The Subordinated Disposition Fee will be
paid only if Shareholders have received a return of 100% of Initial Investor
Capital (through liquidity or distributions) plus an annual Cumulative Return of
six percent from the date shares were purchased from the Company through the
date payment is made. Once Shareholders have been provided with liquidity the
Advisor will be paid any Subordinated Disposition Fee it has earned and does
earn if the return requirements are satisfied. For these purposes Shareholder
will be deemed to have been provided liquidity if the Shares are listed on a
national security exchange or over-the-counter market, included for quotation on
Nasdaq, if shares can be redeemed through the CPA(R):15 redemption plan on a
quarterly basis without delay or some other liquidity terms has been provided
which enables Shareholders to receive cash or marketable securities for their
Shares no less frequently than quarterly. The return requirement will be deemed
satisfied if the total distributions paid by CPA(R):15 satisfy the six percent
annual Cumulative Return requirement and the market value of CPA(R):15 equals or
exceeds 100% of the capital raised by CPA(R):15 (less any amounts distributed
from the sale of refinancing of any property). The market value will be
calculated on the basis of the average market value of the Shares over the 30
trading days beginning 180 days after the Shares are first listed on a stock
exchange if the Shares are listed or included for quotation. If liquidity is
provided through the redemption plan, the value of CPA(R):15 will be the
redemption price, net of any surrender fee, multiplied by the total number of
outstanding Shares. A similar measurement will be used for other forms of
liquidity. To the extent that Subordinated Disposition Fees are not paid by the
Company on a current basis due to the foregoing limitation, the unpaid fees will
be accrued and paid at such time as the limitation has been satisfied. The
Subordinated Disposition Fee may be paid in addition to real estate commissions
paid to non-Affiliates, provided that the total real estate commissions paid to
all Persons by the Company shall not exceed an amount equal to the lesser of:
(i) six percent of the Contract Sales Price of a Property or (ii) the
Competitive Real Estate Commission. In the event this Agreement is terminated
prior to such time as the Shareholders have received a return of 100% of Initial
Investor Capital plus an amount sufficient to pay a Cumulative Return of six
percent from the date shares were purchased from the Company through the date of
termination of this Agreement, an appraisal of the Properties then owned by the
Company shall be made and the Subordinated Disposition Fee

                                      -15-
<PAGE>   16
on Properties previously sold will be deemed earned if the Appraised Value of
the Properties then owned by the Company plus return to Shareholders received
prior to the date of termination of this Agreement is equal to 100% of Initial
Investor Capital (through liquidity or distributions) plus an amount sufficient
to pay a Cumulative Return of six percent from the date shares were purchased
from the Company through the date of termination of this Agreement. In the event
the Company's Shares are listed on a national securities exchange or included
for quotation on Nasdaq and, at the time of such listing, the Advisor has
accrued a Subordinated Disposition Fee which has not been paid, for purposes of
determining whether the subordination conditions have been satisfied,
Shareholders will be deemed to have received a Dividend in an amount equal to
the product of the total number of outstanding Shares and the average of the
closing prices (or average bid and asked quotes) of the Shares over a period,
beginning 180 days after listing of the Shares, of 30 days during which the
Shares are traded.

            (h)   SUBORDINATED INCENTIVE FEE. The Subordinated Incentive Fee
shall be payable to the Advisor in an amount equal to 15% of Cash from Sales and
Financings distributed to the Shareholders after the Shareholders have received
a return of 100% of Initial Investor Capital (through liquidity or
distributions) plus an annual Cumulative Return of six percent from the date
shares were purchased from the Company through the date of payment. Once
Shareholders have been provided with liquidity the Advisor will be paid any
Subordinated Incentive Fee and any Subordinated Disposition Fee it has earned
and does earn if the return requirements are satisfied. For these purposes
Shareholder will be deemed to have been provided liquidity if the Shares are
listed on a national security exchange or over-the-counter market, included for
quotation on Nasdaq, if shares can be redeemed through the CPA(R):15 redemption
plan on a quarterly basis without delay or some other liquidity terms has been
provided which enables Shareholders to receive cash or marketable securities for
their Shares no less frequently than quarterly. The return requirement will be
deemed satisfied if the total distributions paid by CPA(R):15 satisfy the six
percent annual Cumulative Return requirement and the market value of CPA(R):15
equals or exceeds 100% of the capital raised by CPA(R):15 (less any amounts
distributed from the sale of refinancing of any property). The market value will
be calculated on the basis of the average market value of the Shares over the 30
trading days beginning 180 days after the Shares are first listed on a stock
exchange if the Shares are listed or included for quotation. If liquidity is
provided through the redemption plan, the value of CPA(R):15 will be the
redemption price, net of any surrender fee, multiplied by the total number of
outstanding Shares. A similar measurement will be used for other forms of
liquidity. The Company shall have the option to pay such fee in the form of
cash, a promissory note or any combination thereof. The promissory note shall be
fully amortizing over five years, provide for quarterly payments and bear
interest at the prime rate announced from time to time in The Wall Street
Journal.

            (i)   LOANS FROM AFFILIATES. If any loans are made to the Company by
the Advisor or an Affiliate of the Advisor, the maximum amount of interest that
may be charged by such Affiliate shall be the lesser of (i) one percent above
the prime rate of interest publish in The Wall Street Journal and (ii) the rate
that would be charged to the Company by unrelated lending institutions on
comparable loans for the same purpose in the locality of the Property. The terms
of any such loans shall be no less favorable than the terms available between
non-Affiliated Persons for similar commercial loans.

                                      -16-
<PAGE>   17
            (j)   CHANGES TO FEE STRUCTURE. In the event the Shares are listed
on a national securities exchange or are included for quotation on Nasdaq, the
Company and the Advisor shall negotiate in good faith to establish a fee
structure appropriate for a entity with a perpetual life. A majority of the
Independent Directors must approve the new fee structure negotiated with the
Advisor. In negotiating a new fee structure, the Independent Directors shall
consider all of the factors they deem relevant, including but not limited to:
(a) the size of the Advisory Fee in relation to the size, composition and
profitability of the Company's portfolio; (b) the success of the Advisor in
generating opportunities that meet the investment objectives of the Company; (c)
the rates charged to other REITs and to investors other than REITs by Advisors
performing similar services; (d) additional revenues realized by the Advisor and
its Affiliates through their relationship with the Company, including loan
administration, underwriting or broker commissions, servicing, engineering,
inspection and other fees, whether paid by the Company or by others with whom
the Company does business; (e) the quality and extent of service and advice
furnished by the Advisor; (f) the performance of the investment portfolio of the
Company, including income, conversion or appreciation of capital, frequency of
problem investments and competence in dealing with distress situations; and (g)
the quality of the portfolio of the Company in relationship to the investments
generated by the Advisor for its own account. The new fee structure can be no
more favorable to the Advisor than the current fee structure.

            (k)   PAYMENT. Compensation payable to the Advisor pursuant to this
Section 9 shall be paid in cash; provided, however, that the Asset Management
Fees, Performance Fee, and Proxy Management Fee payable pursuant to Section
9(a)(b), and (f) may be paid, at the option of the Advisor, in
the form of: (i) cash, (ii) common stock of the Company, or (iii) a combination
of cash and common stock. The Advisor shall notify the Company in writing of the
form in which the fee shall be paid. Such notice shall be provided no later than
January 15 of each year. If no such notice is provided, the fee shall be paid in
cash. For purposes of the payment of compensation to the Advisor in the form of
stock, the value of each share of common stock shall be: (i) the Net Asset Value
per Share as determined by the most recent appraisal of the Company's assets
performed as of the end of the immediately preceding year by an Independent
Appraiser, or (ii) if an appraisal has not yet been performed, $10 per share.
The Net Asset Value determined on the basis of such appraisal may be adjusted on
a quarterly basis by the Board of Directors of the Company to account for
significant capital transactions. Fees paid in the form of stock shall be paid
pursuant to the terms of the form of the Restricted Stock Agreement attached
hereto as Exhibit A or such other terms as the Advisor and the Company may from
time to time agree.

      10.   EXPENSES.  In addition to the compensation paid to the Advisor
pursuant to Section 9 hereof, the Company shall pay directly or reimburse the
Advisor for the following expenses:

            (i)   the Company's Organizational and Offering Expenses; provided
      however, that within 60 days after the end of the month in which the
      Offering terminates, the Advisor shall reimburse the Company for any
      Organizational and Offering Expense reimbursements received by the Advisor
      pursuant to this Section 10 to the extent that such reimbursements, when
      added to the balance of the Organizational and Offering Expenses
      (excluding selling commissions, and fees paid and expenses reimbursed to

                                      -18-
<PAGE>   19
            (xv)  expenses related to the Properties and Loans and other fees
      relating to making investments including personnel and other costs
      incurred in Property or Loan transactions where a fee is not payable to
      the Advisor; and

            (xvi) all other expenses the Advisor incurs in connection with
      providing services to the Company including reimbursement to the Advisor
      or its Affiliates for the cost of rent, goods, materials and personnel
      incurred by them based upon the compensation of the Persons involved and
      an appropriate share of overhead allocable to those Persons.

      No reimbursement shall be made for the cost of personnel to the extent
that such personnel are used in transactions for which the Advisor receives a
separate fee.

      Expenses incurred by the Advisor on behalf of the Company and payable
pursuant to this Section 10 shall be reimbursed quarterly to the Advisor within
60 days after the end of each quarter. The Advisor shall prepare a statement
documenting the expenses of the Company during each quarter, and shall deliver
such statement to the Company within 45 days after the end of each quarter.

      11.   OTHER SERVICES. Should the Directors request that the Advisor or any
partner or employee thereof render services for the Company other than set forth
in Section 3 hereof, such services shall be separately compensated and shall not
be deemed to be services pursuant to the terms of this Agreement.

      12.   FIDELITY BOND. The Advisor shall maintain a fidelity bond for the
benefit of the Company which bond shall insure the Company from losses of up to
[$5,000,000] and shall be of the type customarily purchased by entities
performing services similar to those provided to the Company by the Advisor.

      13.   REFUND BY ADVISOR. Within 60 days after the end of any fiscal
quarter of the Company which begins following the date the Company first
commences operations, if Operating Expenses of the Company during the fiscal
year, ending at the end of such quarter exceed the greater of (a) two percent of
the Average Invested Assets or (b) 25% of the Net Income of the Company during
that fiscal year and a majority of the Independent Directors find this excess
amount justified based on such unusual and non-recurring factors which they deem
sufficient, the Advisor may be reimbursed in future years for the full amount of
such excess expenses, or any portion thereof, but only to the extent such
reimbursement would not cause the Company's Operating Expenses to exceed the
2%/25% Guidelines in any such year. In no event shall the Operating Expenses
paid by the Company in any twelve month period ending at the end of a fiscal
quarter exceed the 2%/25% Guidelines. All figures used in the foregoing
computation shall be determined in accordance with generally accepted accounting
principles applied on a consistent basis. If the Advisor receives an incentive
fee for the sale of Property, Net Income, for purposes of calculating the
Operating Expenses, shall exclude the gain from the sale of such Property.

      14.   OTHER ACTIVITIES OF THE ADVISOR. Nothing herein contained shall
prevent the Advisor from engaging in other activities, including without
limitation the rendering of advice to other investors (including other REITs)
and the management of other programs advised,

                                      -19-
<PAGE>   20
sponsored or organized by the Advisor or its Affiliates; nor shall this
Agreement limit or restrict the right of any director, officer, employee,
partner or shareholder of the Advisor or its Affiliates to engage in any other
business or to render services of any kind to any other partnership,
corporation, firm, individual, trust or association. The Advisor may, with
respect to any investment in which the Company is a participant, also render
advice and service to each and every other participant therein. The Advisor
shall report to the Directors the existence of any condition or circumstance,
existing or anticipated, of which it has knowledge, which creates or could
create a conflict of interest between the Advisor's obligations to the Company
and its obligations to or its interest in any other partnership, corporation,
firm, individual, trust or association. The Advisor or its Affiliates shall
promptly disclose to the Directors knowledge of such condition or circumstance.
If the Sponsor, Advisor, Director or Affiliates thereof have sponsored other
investment programs with similar investment objectives which have investment
funds available at the same time as the Company, it shall be the duty of the
Directors (including the Independent Directors) to adopt the method set forth in
the Registration Statement or another reasonable method by which properties are
to be allocated to the competing investment entities and to use their best
efforts to apply such method fairly to the Company.

      The Advisor shall be required to use its best efforts to present a
continuing and suitable investment program to the Company which is consistent
with the investment policies and objectives of the Company, but neither the
Advisor nor any Affiliate of the Advisor shall be obligated generally to present
any particular investment opportunity to the Company even if the opportunity is
of character which, if presented to the Company, could be taken by the Company.

      In the event that the Advisor or its Affiliates is presented with a
potential investment which might be made by the Company and by another
investment entity which the Advisor or its Affiliates advises or manages, the
Advisor shall consider the investment portfolio of each entity, cash flow of
each entity, the effect of the acquisition on the diversification of each
entity's portfolio, rental payments during any renewal period, the estimated
income tax effects of the purchase on each entity, the policies of each entity
relating to leverage, the funds of each entity available for investment, the
amount of equity required to make the investment and the length of time such
funds have been available for investment. To the extent that a Property might be
suitable for the Company and for another investment entity which is advised or
managed by the Advisor, the Advisor shall give priority to the investment
entity, including the Company, which has uninvested funds for the longest period
of time. The Advisor may consider the Property for private placement only if
such Property is deemed inappropriate for any investment entity which is advised
or managed by the Advisor, including the Company.

      15.   RELATIONSHIP OF ADVISOR AND COMPANY. The Company and the Advisor
agree that they have not created and do not intend to create by this Agreement a
joint venture or partnership relationship between them and nothing in this
Agreement shall be construed to make them partners or joint venturers or impose
any liability as partners or joint venturers on either of them.

      16.   TERM; TERMINATION OF AGREEMENT. This Agreement shall continue in
force until December 31, 2002 and thereafter shall be automatically renewed from
year to year, unless either party shall give notice in writing of non-renewal to
the other party not less than 60 days before the end of any such year.

                                      -20-
<PAGE>   21
      17.   TERMINATION BY COMPANY. At the sole option of a majority of the
Independent Directors, this Agreement may be terminated immediately by written
notice of termination from the Company to the Advisor if, in addition to the
occurrence of events which would constitute Cause, any of the following events
occur:

      (a)   If the Advisor shall violate any material provision of this
      Agreement, and after written notice of such violation, shall not cure such
      default within 30 days or have begun action within 30 days to cure the
      default which shall be completed with reasonable diligence; or

      (b)   If the Advisor shall be adjudged bankrupt or insolvent by a court of
      competent jurisdiction, or an order shall be made by a court of competent
      jurisdiction for the appointment of a receiver, liquidator, or trustee of
      the Advisor, for all or substantially all of its property by reason of the
      foregoing, or if a court of competent jurisdiction approves any petition
      filed against the Advisor for reorganization, and such adjudication or
      order shall remain in force or unstayed for a period of 30 days; or

      (c)   If the Advisor shall institute proceedings for voluntary bankruptcy
      or shall file a petition seeking reorganization under the federal
      bankruptcy laws, or for relief under any law for relief of debtors, or
      shall consent to the appointment of a receiver for itself or for all or
      substantially all of its property, or shall make a general assignment for
      the benefit of its creditors, or shall admit in writing its inability to
      pay its debts, generally, as they become due.

      Any notice of termination under Section 16 or 17 shall be effective on the
date specified in such notice, which may be the day on which such notice is
given or any date thereafter. The Advisor agrees that if any of the events
specified in Section 17 (b) or (c) shall occur, it shall give written notice
thereof to the Directors within 15 days after the occurrence of such event.

      18.   TERMINATION BY EITHER PARTY. This Agreement may be terminated
immediately without penalty by the Advisor by written notice of termination to
the Company upon the occurrence of events which would constitute Good Reason or
by the Company without cause or penalty by action of the Directors, the
Independent Directors or by action of a majority of the Shareholders, in either
case upon 60 days' written notice.

      19.   ASSIGNMENT PROHIBITION. This Agreement may not be assigned by the
Advisor without the approval of a majority of the Directors (including a
majority of the Independent Directors); provided, however, that such approval
shall not be required in the case of an assignment to a corporation,
partnership, association, trust or organization which may take over the assets
and carry on the affairs of the Advisor, provided: (i) that at the time of such
assignment, such successor organization shall be owned substantially by the then
partners of the Advisor or their Affiliates and only if such entity has a net
worth of at least $5,000,000, and (ii) that a general partner of the Advisor
shall deliver to the Directors a statement in writing indicating the ownership
structure and net worth of the successor organization and a certification from
the new Advisor as to its net worth. Such an assignment shall bind the assignees
hereunder in the same manner as the Advisor is bound by this Agreement. The
Advisor may assign any rights to receive fees or other payments under this
Agreement without obtaining the approval of

                                      -21-
<PAGE>   22
the Directors. This Agreement shall not be assigned by the Company without the
consent of the Advisor, except in the case of an assignment by the Company to a
corporation or other organization which is a successor to the Company, in which
case such successor organization shall be bound hereunder and by the terms of
said assignment in the same manner as the Company is bound by this Agreement.

      20.   PAYMENTS TO AND DUTIES OF ADVISOR UPON TERMINATION.

            (a)   After the Termination Date, the Advisor shall not be entitled
to compensation for further services hereunder except it shall be entitled to
receive from the Company within 30 days after the effective date of such
termination the following:

            (i)   all unpaid reimbursements of Organization and Offering
      Expenses and of Operating Expenses payable to the Advisor;

            (ii)  all earned but unpaid Asset Management Fees and Performance
      Fees payable to the Advisor prior to the termination of this Agreement;

            (iii) all earned but unpaid Subordinated Acquisition Fees and all
      unaccrued Subordinated Acquisition Fees, in each case payable to the
      Advisor relating to the acquisition of any Property prior to the
      termination of this Agreement;

           (iv)  all earned but unpaid Subordinated Disposition Fees payable to
      the Advisor relating to the sale of any Property prior to the termination
      of this Agreement;

            (v)   all earned but unpaid Loan Refinancing Fees payable to the
      Advisor relating to the financing or refinancing of any Property prior to
      the termination of this Agreement; and

            (vi)  all earned but unpaid Property Management Fees payable to the
      Advisor or its Affiliates relating to the management of any property prior
      to the termination of this Agreement.

      Notwithstanding the foregoing, in the event this Agreement is terminated
by the Company for Cause or by the Advisor for other than Good Reason, the
Advisor will not be entitled to receive the sums in subparagraphs 20(a)(i)-(vi),
above. All amounts payable to the Advisor in the event of a termination shall be
evidenced by a non-interest bearing promissory note (the "Note") having a
principal amount of the unpaid amount payable to the Advisor.

      (b)   If this Agreement is terminated by the Company for any reason other
than Cause, by either party in connection with a Change of Control, or by the
Advisor for Good Reason, the Advisor shall be entitled to payment of the
Termination Fee.

      (c)   The Termination Fee shall be paid in a manner determined by the
Directors, but in no event shall any portion of the Termination Fee remain
unpaid three years after the termination, non-renewal or substantial
modification of this Agreement, nor shall the

                                      -22-
<PAGE>   23
Termination Fee be paid in less than 12 equal quarterly installments, with
interest, on the unpaid balance at the prime rate of interest then in effect as
announced by The Bank of New York. Notwithstanding the preceding sentence, any
amounts which may be deemed payable at the date the obligation to pay the
Termination Fee is incurred (i) shall be an amount which provides compensation
to the Advisor only for that portion of the holding period for the respective
Properties during which the Advisor provided services to the Company, (ii) shall
not be due and payable until the Property to which such fees relate is sold or
refinanced, and (iii) shall not bear interest until the Property to which such
fees relate is sold or refinanced. A portion of the Termination Fee shall be
paid as each Property owned by the Company on the Termination Date is sold. The
portion of the Termination Fee payable upon each such sale shall be equal to (i)
the Termination Fee multiplied by (ii) the percentage calculated by dividing the
Appraised Value (at the Termination Date) of the Property sold by the Company
divided by the total Appraised Value (at the Termination Date) of all Properties
owned by the Company on the Termination Date.

      The Note for amounts payable as described above shall mature upon the
liquidation of the Company (or ten years from date of issuance whichever is
earlier) and shall be payable at any time prior to maturity. The compensation
payable under this Subsection shall be paid or delivered to the Advisor within
30 days after funds shall become available to the Company for the making of such
payments.

      (d)   Notwithstanding the foregoing, the Advisor shall not be entitled to
payment of the Termination Fee in the event this Agreement is terminated because
of failure of the Company and the Advisor to establish, pursuant to Section 9(j)
hereof, a fee structure appropriate for an entity with a perpetual life in the
event the Shares are listed on a national securities exchange or are included
for quotation on Nasdaq.

      (e)   The Advisor shall promptly upon termination:

            (i)   pay over to the Company all money collected and held for the
      account of the Company pursuant to this Agreement, after deducting any
      accrued compensation and reimbursement for its expenses to which it is
      then entitled;

            (ii)  deliver to the Directors a full accounting, including a
      statement showing all payments collected by it and a statement of all
      money held by it, covering the period following the date of the last
      accounting furnished to the Directors;

            (iii) deliver to the Directors all assets, including Properties and
      Loans, and documents of the Company then in the custody of the Advisor;
      and

            (iv)  cooperate with the Company to provide an orderly management
      transition.

      21.   INDEMNIFICATION BY THE COMPANY. The Company shall indemnify and hold
harmless the Advisor and its Affiliates, including their respective officers,
directors, partners and employees, from all liability, claims, damages or losses
arising in the performance of their duties hereunder, and related expenses,
including reasonable attorneys' fees, to the extent such liability, claims,
damages or losses and related expenses are not fully reimbursed by insurance,
subject to

                                      -23-
<PAGE>   24
any limitations imposed by the laws of the State of Maryland, the Articles of
Incorporation or the Bylaws of the Company. Notwithstanding the foregoing, the
Advisor shall not be entitled to indemnification or be held harmless pursuant to
this Section 21 for any activity which the Advisor shall be required to
indemnify or hold harmless the Company pursuant to Section 22.

      22.   INDEMNIFICATION BY ADVISOR. The Advisor shall indemnify and hold
harmless the Company from liability, claims, damages, taxes or losses and
related expenses including attorneys' fees, to the extent that such liability,
claims, damages, taxes or losses and related expenses are not fully reimbursed
by insurance and are incurred by reason of the Advisor's bad faith, fraud,
willful misfeasance, misconduct, negligence or reckless disregard of its duties.

      23.   NOTICES. Any notice, report or other communication required or
permitted to be given hereunder shall be in writing unless some other method of
giving such notice, report or other communication is accepted by the party to
whom it is given, and shall be given by being delivered by hand or by overnight
mail or other overnight delivery service to the addresses set forth herein:

      Either party may at any time give notice in writing to the other party of
a change in its address for the purposes of this Section 23.

      24.   MODIFICATION. This Agreement shall not be changed, modified,
terminated, or discharged, in whole or in part, except by an instrument in
writing signed by both parties hereto, or their respective successors or
assignees.

      25.   SEVERABILITY. The provisions of this Agreement are independent of
and severable from each other, and no provision shall be affected or rendered
invalid or unenforceable by virtue of the fact that for any reason any other or
others of them may be invalid or unenforceable in whole or in part.

      26.   CONSTRUCTION. This Agreement shall be governed by, construed and
enforced in accordance with the laws of the State of New York.

      27.   ENTIRE AGREEMENT. This Agreement contains the entire agreement and
understanding among the parties hereto with respect to the subject matter
hereof, and supersedes all prior and contemporaneous agreements, understandings,
inducements and conditions, express or implied, oral or written, of any nature
whatsoever with respect to the subject matter hereof. The express terms hereof
control and supersede any course of performance and/or usage of the trade
inconsistent with any of the terms hereof. This Agreement may not be modified or
amended other than by an agreement in writing.

      28.   INDULGENCES, NOT WAIVERS. Neither the failure nor any delay on the
part of a party to exercise any right, remedy, power or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, remedy, power or privilege preclude any other or further
exercise of the same or of any other right, remedy, power or privilege, nor
shall any waiver of any right, remedy, power or privilege with respect to any
occurrence be construed as a waiver of such right, remedy, power or privilege
with respect to any other occurrence. No waiver shall be effective unless it is
in writing and is signed by the party asserted to have granted such waiver.

      29.   GENDER. Words used herein regardless of the number and gender
specifically used, shall be deemed and construed to include any other number,
singular or plural, and any other gender, masculine, feminine or neuter, as the
context requires.

      30.   TITLES NOT TO AFFECT INTERPRETATION. The titles of Sections and
subsections contained in this Agreement are for convenience only, and they
neither form a part of this Agreement nor are they to be used in the
construction or interpretation hereof.

      31.   EXECUTION IN COUNTERPARTS. This Agreement may be executed in any
number of counterparts, each of which shall be deemed to be an original as
against any party whose signature appears thereon, and all of which shall
together constitute one and the same instrument. This Agreement shall become
binding when one or more counterparts hereof, individually or taken together,
shall bear the signatures of all of the parties reflected hereon as the
signatories.

      32.   NAME. W.P. Carey & Co. LLC has a proprietary interest in the name
"Corporate Property Associates" and "CPA.(R)" Accordingly, and in recognition of
this right, if at any time the Company ceases to retain Carey Asset Management
Corp., or an Affiliate thereof to perform the services of Advisor, the Directors
of the Company will, promptly after receipt of written request from Carey Asset
Management Corp., cease to conduct business under or use the name "Corporate
Property Associates" or "CPA(R)" or any diminutive thereof and the Company shall
use its best efforts to change the name of the Company to a name that does not
contain the name "Corporate Property Associates" or "CPA(R)" or any other word
or words that might, in the sole discretion of the Advisor, be susceptible of
indication of some form of relationship between the Company and the Advisor or
any Affiliate thereof. Consistent with the foregoing, it is specifically
recognized that the Advisor or one or more of its Affiliates has in the past and
may in the future organize, sponsor or otherwise permit to exist other
investment vehicles (including vehicles for investment in real estate) and
financial and service organizations having "Corporate Property Associates" or
"CPA(R)" as a part of their name, all without the need for any consent (and
without the right to object thereto) by the Company or its Directors.

      33.   INITIAL INVESTMENT. The Advisor has contributed to the Company
$200,000 in exchange for 20,000 Shares (the "Initial Investment"). The Advisor
or its Affiliates may not sell any of the Shares purchased with the Initial
Investment during the term of this Agreement. The restrictions included above
shall not continue to apply to any Shares other than the Share acquired through
the Initial Investment acquired by the Advisor or its Affiliates. The Advisor
shall not vote any Shares it now owns or hereafter acquires in any vote for the
election of

                                      -25-
<PAGE>   26
Directors or any vote regarding the approval or termination of any contract with
the Advisor or any of its Affiliates.

      IN WITNESS WHEREOF, the parties hereto have executed this Advisory
Agreement as of the day and year first above written.

EXHIBIT A

RESTRICTED STOCK AGREEMENT

      This RESTRICTED STOCK AGREEMENT dated ________________, by and between
Corporate Property Associates 15 Incorporated ("CPA(R):15"), a Maryland
corporation and Carey Asset Management Corp., a Delaware corporation and
wholly-owned subsidiary of W.P. Carey & Co. LLC (the "Advisor").

WITNESSETH

      WHEREAS, CPA(R):15 and Advisor entered into an Advisory Agreement (the
"Advisory Agreement") pursuant to which Advisor provides various services to
CPA(R):15;

      WHEREAS, pursuant to the Advisory Agreement, CPA(R):15 is required to pay
certain fees to the Advisor and the Advisor may request that certain fees be
paid with common stock of the Company; and

      WHEREAS, the Advisor has requested that CPA(R):15 pay a portion of the
fees due to Advisor in the form of shares of common stock of CPA(R):15.

      NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements contained herein, the parties hereto agree as follows.

            1.    Payment of Fees with Stock.  CPA(R):15 hereby grants to
Advisor __________ shares of common stock of CPA(R):15 (the "Shares").

            2.    Restrictions. The Shares are subject to vesting over a
five-year period. The Shares shall vest ratably over a five-year period with 20%
of the Shares paid in each payment vesting on each of the first through fifth
anniversary of the date hereof. Prior to the vesting of the ownership of the
Shares in the Advisor, the Shares may not be transferred by the Advisor.

            3.    Immediate Vesting. Upon the expiration of the Advisory
Agreement for any reason other than a termination for Cause under paragraph 17
of the Advisory Agreement or upon a "Change of Control" of CPA(R):15 (as defined
below), all Shares granted to the Advisor hereunder shall vest immediately and
all restrictions shall lapse. For purposes of this Agreement, a "Change of
Control" of the Company shall be deemed to have occurred if there has been a

                                       A-1
<PAGE>   28
change in the ownership of the Company of a nature that would be required to be
reported in response to the disclosure requirements of Schedule 14A of
Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), as enacted and in force on the date hereof, whether or not
the Company is then subject to such reporting requirements; provided, however,
that, without limitation, a Change of Control shall be deemed to have occurred
if:

            (i) any "person," as such term is used in Sections 13(d) and 14(d)
of the Exchange Act (other than the Company, any of its subsidiaries, any
trustee, fiduciary or other person or entity holding securities under any
employee benefit plan of the Company or any of its subsidiaries), together with
all "affiliates" and "associates" (as such terms are defined in Rule 14b-2 under
the Exchange Act) of such person, shall become the "beneficial owner" (as such
term is defined in Rule 13d-3 under the Exchange Act), directly or indirectly,
of securities of the Company representing 25% or more of either (A) the combined
voting power of the Company's then outstanding securities having the right to
vote in an election of the Company's Board of Directors ("Voting Securities") or
(B) the then outstanding common stock of the Company (in either such case other
than as a result of acquisition of securities directly from the Company);

            (ii) persons who, as of the date hereof, constitute the Company's
Board of Directors (the "Incumbent Directors") cease for any reason, including
without limitation, as a result of a tender offer, proxy contest, merger or
similar transaction, to constitute at least a majority of the Board of
Directors, provided that any person becoming a director of the Company
subsequent to the date hereof whose election or nomination for election was
approved by a vote of at least a majority of the Incumbent Directors shall, for
purposes of this Agreement, be considered an Incumbent Director; or

            (iii) the stockholders of the Company shall approve (A) any
consolidation or merger of the Company or any subsidiary where the stockholders
of the Company, immediately prior to the consolidation or merger, would not,
immediately after the consolidation or merger,

                                       A-2
<PAGE>   29
beneficially own (as such term is defined in Rule 13d-3 under the Exchange Act),
directly or indirectly, shares representing in the aggregate 50% or more of the
voting equity of the entity issuing cash or securities in the consolidation or
merger (or of its ultimate parent entity, if any), (B) any sale, lease, exchange
or other transfer (in one transaction or a series of transactions contemplated
or arranged by any party as a single plan) of all or substantially all of the
assets of the Company or (C) any plan or proposal for the liquidation or
dissolution of the Company.

            Notwithstanding the foregoing, a "Change of Control" shall not be
deemed to have occurred for purposes of the foregoing clause (i) solely as the
result of an acquisition of securities by the Company which, by reducing the
number of Shares of Common Stock outstanding, increases (A) the proportionate
number of Shares beneficially owned by any person to 25% or more of the Shares
then outstanding, or (B) the proportionate voting power represented by the
Shares beneficially owned by any person to 25% or more of the combined voting
power of all then outstanding voting Securities; provided, however, that if any
person referred to in clause (A) or (B) of this sentence shall thereafter become
the beneficial owner of any additional Shares or other Voting Securities (other
than pursuant to a Share split, Share dividend, or similar transaction), then a
"Change of Control" shall be deemed to have occurred for purposes of the
foregoing clause (i).

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.

2001, by and between CORPORATE PROPERTY ASSOCIATES 15 INCORPORATED, a Maryland
corporation (the "Company"), and CAREY FINANCIAL CORPORATION, a Delaware
corporation ("Carey Financial").

         WHEREAS, the Company proposes to raise up to $400,000,000 through the
sale of shares of common stock of the Company (the "Shares") for investment in
real property as described in a Registration Statement on Form S-11 (No.
333-_____) filed with the Securities and Exchange Commission (the "Registration
Statement"); and

         WHEREAS, the Company desires to retain Carey Financial and Carey
Financial desires to undertake to coordinate the performance of certain
wholesaling services for the Company pursuant to this Agreement on the terms and
subject to the conditions hereinafter set forth and subject to the limitations,
if any, set forth in the final Prospectus which will be included in the
Registration Statement.

         NOW THEREFORE, in consideration of the mutual promises herein made and
for other good and valuable consideration, and intending to be legally bound
hereby, the parties hereto agree as follows:

         1. The Company hereby retains Carey Financial to provide the following
services for the Company:

         (a) Carey Financial shall develop and prepare sales literature to be
         used by the Company in the offer and sale of the Shares (the
         "Offering"), which sales literature shall comply with the Securities
         Act of 1933, as amended ("the "Securities Act"), and the regulations
         thereunder, the Rules of Fair Practice of the National Association of
         Securities Dealers, Inc. (the "RFP") and the "blue sky" laws of any
         jurisdiction in which such material is used ("Blue Sky Law"). The sales
         literature may include, but not be limited to, a slide presentation, a
         property acquisition report, a brochure and seminar invitations for
         presentation and distribution to the public and an audio program, a
         video program and a brochure for presentation and distribution to
         broker-dealers.

         (b) Carey Financial shall assist broker-dealers and registered
         investment advisors participating in the Offering by coordinating
         broker-dealer and registered investment advisor seminars, informational
         meetings, preparing and distributing brochures and other sales
         literature designed for broker-dealers and registered investment
         advisors and providing information and answering any questions with
         regard to the Offering.

         (c) Carey Financial shall assist the Company in enlisting
         broker-dealers and registered investment advisors to participate in the
         Offering as selected dealers.

         2. In consideration for providing the above services, Carey Financial
shall receive reimbursement for identified expenses incurred in connection with
its wholesaling activities described in Section 1 above, including but not
limited to: (a) travel and entertainment expenses; (b) the cost of compensation
paid to employees of Carey Financial in connection with wholesaling activities;
(c) expenses incurred in coordinating broker-dealer and registered investment
advisor seminars and meetings; and (d) wholesaling fees and wholesaling expense
reimbursements paid to it or its Affiliates or other entities.

         3. The Company shall, at the direction of Carey Financial, reimburse
directly all other entities for marketing and wholesaling expenses of the type
described in clauses (a), (b) and (c) of Section 2 hereof incurred directly by
those entities at the request of Carey Financial.

         4. Carey Financial shall adopt procedures which it, in its sole
discretion, deems adequate to monitor compliance with the limitation in Rule
2740 of the RFP and IM 2740 thereto on aggregate compensation to it and all
broker-dealers participating in the Offering. In no event will the amounts paid
hereunder, when combined with all other underwriting compensation paid in
connection with the offering, exceed 10% of Gross Offering Proceeds plus 0.5%
for bona fide due diligence expenses.

         5. The Company hereby represents and warrants to Carey Financial that
the representations and warranties of it set forth in Section 2 of the Sales
Agency Agreement, dated the date hereof, between the Company and Carey
Financial, as Sales Agent (the "Sales Agency Agreement"), are true and correct
in all respects, and that such representations and warranties are hereby
incorporated by reference herein (together with all related definitions and
cross-references) as if set forth in full herein.

         6. The Company hereby covenants to Carey Financial that it will honor
and perform each of the covenants made by it in Section 4 of the Sales Agency
Agreement, and agrees that such covenants are incorporated by reference herein
(together with all related definitions and cross-references) as if set forth in
full herein.

         7. The term of this Agreement shall commence on the date hereof and
shall continue until such time as the Offering is completed. Notwithstanding the
foregoing, this Agreement may be terminated without the payment of any penalty
by either party upon not less than 60 days' notice in writing to the other
party, except for the payment to Carey Financial of unreimbursed expenses
incurred by it prior to the date of termination.

         8. Carey Financial may assign any of its rights or delegate the
performance of any of its obligations hereunder to its Affiliates or any other
entity, provided, however, that no such delegation shall relieve Carey Financial
of its obligations hereunder.

         9. The parties hereto agree that they have not created a joint venture
or partnership relationship between them, that Carey Financial shall be deemed
to be an independent contractor and not for any purpose to be an employee of the
Company.

provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns.

York applicable to agreements made and to be performed entirely within such
state.

unenforceability without invalidating or rendering unenforceable the remaining
provisions hereof, and any such invalidity or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provisions in any
other jurisdiction.
