5. Dividends. All dividend equivalents declared and paid by the Company on Restricted Stock Units shall be deferred until the lapsing of the Transfer Restrictions pursuant to Section 3. The deferred dividend equivalents shall be held by the Company for the account of the Grantee until the Vesting Date, at which time the dividend equivalents, with no interest thereon, shall be paid to the Grantee. Upon the forfeiture of the Restricted Stock Units pursuant to Section 3, any deferred dividend equivalents shall be forfeited to the Company.
