MassMutual, at its option, can convert the principal amount of the Note into the Issuer's common shares.

4. The inclusion of MassMutual held securities of the Issuer shall not be construed as an admission that Barings is for the purpose of Section 16 of the Exchange Act, the direct or indirect beneficial owner of the securities of the Issuer beneficially owned by MassMutual.
