Use of Proceeds

Upon issuance, the net proceeds from the sale of the notes will be deposited into a Morgan Stanley account for tracking our green project disbursements, as described below.  We expect that Morgan Stanley consolidated subsidiaries will, over time, allocate funds in aggregate amounts equal to the balance of this account to our existing and future renewable energy and energy efficiency projects.  These projects relate to the development of initiatives within the Morgan Stanley group or investments in third party projects, in accordance with Morgan Stanley’s green bond project investment criteria, as set forth below:

Renewable Energy Investments

Wind Energy Generation – activities to generate energy from wind, including:

·   The development, construction or operation of wind farms.

·   Operational, production or manufacturing facilities related to wind energy development.

·   Transmission infrastructure for use by wind farms.

Solar Energy Generation – activities to generate energy from solar resources, including:

·   The development, construction or operation of solar electricity generation facilities.

·   Operational, production or manufacturing facilities related to solar energy development.

·   Transmission infrastructure for use by solar electricity generation facilities.

Energy Efficiency Investments

·   Investments in equipment, systems, products or services that help reduce energy consumption, including waste heat/energy recovery systems, systems to reduce transmission and distribution losses and energy efficient lighting and heating/cooling mechanisms.  These investments exclude projects to retrofit or otherwise upgrade power plants that primarily use fossil fuels in order to improve their efficiency or reduce their environmental emissions.

So long as the notes are outstanding, our internal records will show, at any time, how our consolidated subsidiaries have allocated the amounts equal to the net proceeds from the sale of the notes, including to existing eligible green projects as described below.  Pending the allocation, the net proceeds will remain in the Morgan Stanley account and will be invested in cash, cash equivalents, U.S. government securities, U.S. agency securities, U.S. agency mortgage-backed securities or non-U.S. government securities.  As funds are allocated to eligible green projects, the same amount of money will be released from the Morgan Stanley account.  Funds released from the Morgan Stanley account may not necessarily be transferred or otherwise transmitted to the consolidated subsidiaries with actual funding obligations to the renewable energy or energy efficiency projects, and so will be released from the Morgan Stanley account to be used by us for general corporate purposes.  See also “Use of Proceeds” in the accompanying prospectus.

Eligible green projects will include existing projects with disbursements made by our consolidated subsidiaries from the 12 months preceding the issue date of the notes to the issue date of the notes.  Consequently, on the issue date of the notes, an equivalent amount of the net proceeds from the sale of the notes will be released from the Morgan Stanley account to be used for general corporate purposes.  Eligible green projects will also include projects with disbursements to be made following the issue date of the notes and up to the maturity date of the notes.  These future investments in eligible green projects may include those made by Morgan Stanley or any of our consolidated subsidiaries.

The term of any eligible green project may be shorter or longer than the term of the notes and any such project may mature or be sold before or after the maturity date of the notes.  In the case of any eligible green project investment that matures or is sold before the maturity date of the notes, the proceeds of that investment will become fungible with our other capital resources.  If any eligible green project remains outstanding after the maturity date of the notes, neither we nor any of our consolidated subsidiaries will be required to terminate the financing of such project on the maturity date of the notes.

Payment of principal and interest on the notes will be made from our general funds and will not be directly linked to the performance of any eligible green project.

During the term of the notes, we intend to provide annual updates regarding (i) the overall aggregate allocation of funds from the Morgan Stanley account to the different categories of existing and future eligible green projects and (ii) assertions by management that amounts equal to the net proceeds from the sale of the notes have been invested in either qualifying eligible green projects or in cash or other financial instruments described above.  The assertions will be accompanied by a report from an independent accountant in respect of the independent accountant’s examination of management’s assertion conducted in

PS-2

accordance with attestation standards established by the American Institute of Certified Public Accountants.  These assertions and accompanying reports will continue until the net proceeds are fully allocated but may otherwise be discontinued at any time in our sole discretion.

If the use of the net proceeds by us is a factor in your decision to invest in the notes, you should consider the foregoing discussion and consult with your counsel or other advisors before making an investment in the notes.
