* In order to comply with the requirements of Section 19 of the Investment Company Act of 1940, as amended, each of the Funds noted above posted to the DTC bulletin board and sent to their shareholders as of the applicable record date a Section 19 notice with the previous dividend payment. The Section 19 notice was provided not for tax reporting purposes but for informational purposes only. This information can be found in the “Closed-End Funds” section of www.blackrock.com. If applicable, the final determination of the source and tax characteristics of all distributions in 2010 will be made after the end of the year.

BlackRock Enhanced Government Fund, Inc. (NYSE:EGF) (“EGF”) has adopted a level distribution plan (the “Plan”) and employs either a managed distribution or an option over-write policy to support a level distribution of income, capital gains and/or return of capital. The fixed amounts distributed per share are subject to change at the discretion of EGF’s Board. Under its Plan, EGF will distribute all available investment income to its shareholders, consistent with its primary investment objectives and as required by the Internal Revenue Code of 1986, as amended (the “Code”). If sufficient investment income is not available on a quarterly/monthly basis, EGF will distribute long-term capital gains and or return capital to their shareholders in order to maintain a level distribution.

EGF’s estimated sources of the distributions paid as of September 30, 2010 are as follows:

The amounts and sources of distributions reported are only estimates and are not provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon EGF’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. EGF will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.
