 risk associated with scheduled principal and
interest payments. The second element represents Moody’s evaluation of risk associated with the ability to receive purchase price
upon demand (“demand feature”), using a variation of the MIG rating scale, the Variable Municipal Investment Grade or VMIG
rating. The rating transitions on the VMIG scale differ from those on the Prime scale to reflect the risk that external liquidity support
generally will terminate if the issuer’s long-term rating drops below investment grade.

VMIG 1This designation
denotes superior credit quality. Excellent protection is afforded by the superior short-term credit strength of the liquidity provider
and structural and legal protections that ensure the timely payment of purchase price upon demand.

VMIG 2This designation
denotes strong credit quality. Good protection is afforded by the strong short-term credit strength of the liquidity provider and structural

and structural and legal protections that ensure the timely payment of purchase price upon demand.

SGThis designation denotes

investment grade short-term rating or may lack the structural and/or legal protections necessary to ensure the timely payment of purchase
price upon demand.

eExpected Ratings Indicator.
To address market demand for timely information on particular types of credit ratings, Moody’s has licensed to certain third parties
the right to generate “Expected Ratings.” Expected Ratings are designated by an “e” after the rating code, and
are intended to anticipate Moody’s forthcoming rating assignments based on reliable information from third party sources (such as
the issuer or underwriter associated with the particular securities) or established Moody’s rating practices (i.e., medium
term notes are typically, but not always, assigned the same rating as the note’s program rating). Expected Ratings will exist only
until Moody’s confirms the Expected Rating, or issues a different rating for the relevant instrument. Moody’s encourages market
participants to contact Moody’s Ratings Desk or visit www.moodys.com if they have questions, or wish Moody’s to confirm

(P)Provisional Ratings.
