STYLE="font-family:Times New Roman" SIZE="2">Article V of the By-Laws of Alcoa provides that Alcoa shall indemnify, under specified circumstances, persons who were or are directors, officers or employees of Alcoa or who served or serve other
business entities at the request of Alcoa. Under these By-Law provisions, a person who is wholly successful in defending a claim will be indemnified for any reasonable expenses. To the extent a person is not successful in defending a claim,
reasonable expenses of the defense and any liability incurred are to be indemnified under these provisions only where independent legal counsel or another disinterested person selected by the board of directors determines that such person acted in
good faith and in a manner such person reasonably believed to be in, or not opposed to, the best interests of Alcoa, and in addition with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct of such person was
unlawful. Any expense incurred with respect to any claim may be advanced by Alcoa if the recipient agrees to repay such amount if it is ultimately determined that such recipient is not to be indemnified pursuant to Article V. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:13%"><FONT STYLE="font-family:Times New Roman" SIZE="2">The foregoing By-Law provisions generally parallel Sections 1741 and 1745 of the Pennsylvania Business Corporation Law

<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:13%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Section&nbsp;1746 of the PBCL and the By-Laws provide for increased indemnification protections for directors, officers and others.
Indemnification may be provided by Pennsylvania corporations in any case except where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:13%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Section&nbsp;1713 of the PBCL also sets forth a framework whereby Pennsylvania corporations, with the approval of the shareholders, may
limit the personal liability of directors for monetary damages except where the act or omission giving rise to a claim constitutes self-dealing, willful misconduct or recklessness. The section does not apply to a director&#146;s responsibility or
liability under a criminal or tax statute and may not apply to liability under Federal statutes, such as the Federal securities laws. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:13%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">Alcoa&#146;s Articles of Incorporation and By-Laws were amended by the shareholders to implement the increased protections made available to directors under the PBCL as described in the preceding
paragraph. Article VIII of the By-Laws provides that, except as prohibited by law, every director of Alcoa shall be entitled as of right to be indemnified by Alcoa for expenses and any and all liability paid or incurred by such person by reason of
such person being or having been a director of Alcoa. Expenses incurred with respect to any claim may be advanced by Alcoa, subject to certain exceptions. The shareholders have also approved a form of indemnity agreement. Alcoa has entered into such
an indemnity agreement with each of its current directors and officers. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:13%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Alcoa has purchased a directors and officers
liability insurance policy with an aggregate limit of $500 million for liability of directors and officers. The insurance includes within that limit $250 million of coverage, subject to a retention, for reimbursement to Alcoa for indemnification
provided to directors and officers. The policy has an expiration date of October&nbsp;1, 2013 and provides liability insurance and reimbursement coverage for Alcoa, and its directors and officers that is permitted by the laws of Pennsylvania.

employee benefit plan, and may take such steps as may be deemed appropriate by the board of directors, including purchasing and maintaining insurance, entering into contracts, including, without limitation, contracts of indemnification between Alcoa
