Item 5 - Fees and Compensation
INVESTMENT ADVISORY SERVICES
The client can engage CPALLC to provide discretionary investment advisory services on a
fee-only basis. CPAS’ annual investment advisory fee is based upon a percentage (%) of
the market value of the assets placed under CPAS’ management (between 0.35% and
1.50%) as follows:     Market Value of Portfolio    % of Assets
                        Up to $500k                        1.50%
                        $500,001 - $1,000,000              1.25%
                        $1,000,001 - $2,000,000            1.00%
                        $2,000,001 - $3,000,000            0.75%
                        $3,000,001 - $5,000,000            0.50%
                        More than $5,000,001               0.35%
CPAS’ annual investment advisory fee shall include investment advisory services, and, to
the extent specifically requested by the client, financial planning services. In the event the
client requires extraordinary financial planning services (to be determined in the sole
discretion of CPAS), CPAS may determine to charge for such additional services, the dollar
amount of which shall be set forth in a separate written notice to the client.
Clients may elect to have the CPAS’ advisory fees deducted from their custodial account.
Both CPAS’ Asset Management Agreement and the custodial/ clearing agreement may
authorize the custodian to debit the account for the amount of CPAS' investment advisory
fee and to directly remit that management fee to CPAS in compliance with internal
procedures. In the limited event that CPAS bills the client directly, payment is due upon
receipt of CPAS’ invoice. CPAS shall deduct fees and/or bill clients quarterly in arrears,
based upon the market value of the assets on the last business day of the previous
quarter.
As discussed below, unless the client directs otherwise or an individual client’s
circumstances require, CPAS shall generally recommend that SEI serve as the broker-
dealer/custodian for client investment management assets.
Broker-dealers such as SEI charge brokerage commissions and/or transaction fees for
effecting certain securities transactions (i.e. transaction fees are charged for certain no-
load mutual funds, commissions are charged for individual equity and fixed income
securities transactions).
In addition to CPAS’ investment management fee, brokerage commissions and/or
transaction fees, clients will also incur, relative to all mutual fund and exchange traded
fund purchases, charges imposed at the fund level (e.g. management fees and other fund
expenses).

                    CORNERSTONE PROFESSIONAL ADVISOR SERVICES, LLC.

When beneficial to the client, individual fixed-income and/or equity transactions may be
effected through broker/dealers with whom CPAS and/or the client have entered into
arrangements for prime brokerage clearing services, including effecting certain client
transactions through other various SEC-registered and the Financial Industry Regulatory
Authority (“FINRA”) broker-dealers (in which event, the client shall incur both the
transaction fee charged by the executing broker-dealer and a “tradeaway” fee charged
by SEI).
In the event that the client desires, the client can engage certain of CPAS’ principals or
associated persons in their individual capacities as registered representatives of SA Stone
Wealth Management, Inc., a FINRA broker-dealer, to implement investment
recommendations. In the event the Client chooses to purchase investment products
through Michael Welger as a registered representative of SA Stone Wealth Management,
Inc., brokerage commissions will be charged by SA Stone Wealth Management, Inc., to
effect securities transactions, a portion of which commissions shall be paid by SA Stone
Wealth Management, Inc prior to effecting any transactions, the Client will be required
to enter into a new account agreement with SA Stone Wealth Management, Inc.
Advice offered by certain principals and associated persons of CPAS (“IARs”) may involve
investments in mutual funds. Mutual funds may carry loads (i.e. sales charges) that may
be up-front or on a contingent deferred basis or be no-loads with no initial or contingent
deferred sales charges. Fees paid to CPAS or any IAR for advisory services are separate
from the fees and expenses charged to shareholders of mutual fund shares by the mutual
fund companies. A complete explanation of fees and expenses charged by mutual funds
is contained in each mutual fund's prospectus. Clients are advised that certain IARs are
Registered Representatives of SA Stone Wealth Management, Inc., a registered
Broker/Dealer, members of FINRA and SIPC. Therefore, IAR’s have a conflict of interest in
recommending mutual funds that carry a load since such mutual funds will pay IAR, in his
or her capacity as a Registered Representative of SA Stone Wealth Management.
A conflict of interest may exist between the interests of CPAS and/or its IARs and the
interests of Client in that CPAS and Michael Welger offer financial planning and
investment advisory services for a fee and also offer various securities products for which
they may be paid a commission in his capacity as a Registered Representative of SA Stone
Wealth Management, Inc.
Clients are advised that the investment recommendations and advice offered by CPAS are
not legal advice or accounting advice. Clients should coordinate and discuss the impact of
financial advice with their attorney and/or accountant. Clients are advised that it is
necessary to inform CPAS promptly with respect to any changes in Client's financial
situation and investment goals and objectives. Failure to notify CPAS of any such changes
could result in investment recommendations not meeting the needs of Client.
At all times clients have the option to purchase investment products recommended by
CPAS through unaffiliated brokers or agents.
