from any meeting of the number of shares required by the laws of the State of
Alabama, by the articles of incorporation of the Corporation or by these
by-laws for action upon any given matter shall not prevent action at such
meeting upon any other matter or matters which may properly come before the
meeting, if the number of shares required in respect of such other matter
shall be present.

          (8) VOTING. At each meeting of the shareholders, each holder of
record of shares entitled to vote thereat, shall be entitled to one vote in

registered in his name on the books of the Corporation: (i) on the date fixed
pursuant to Section 3 of Article VII of these by-laws as the record date for
the determination of shareholders entitled to vote at such meeting,
notwithstanding the sale, or other disposal or transfer on the books of the
Corporation of such share on or after the date so fixed; or (ii) at the date of
such meeting if no such record date shall have been fixed. Shares of its on
belonging to the Corporation shall not be voted directly or indirectly. Persons
holding in a fiduciary capacity shares having voting rights shall be entitled to
vote the shares so held, and persons whose shares having voting rights pledged
shall be entitled to vote, unless in the transfer by the pledgor on the books of
the Corporation he shall have expressly empowered the pledgee to vote thereon,
in which case only the pledgee or his proxy, may represent said shares and vote
thereon. Any vote of shares may be cast by the shareholder entitled thereto in
person or by his proxy appointed by an instrument in writing subscribed by such
shareholder or by his attorney thereunto authorized, and delivered to the
secretary of the meeting. At all meetings of the shareholders, all matters
(except in special cases where other provision is made by statute, and except as
otherwise provided in these by-laws or in the certificate of incorporation)

                                       3



present in person or by proxy at any meeting and entitled to vote thereat,
the vote on any question need not be by ballot. On a vote by ballot, each

Corporation and to such registrar, transfer agent and/or transfer clerk as
may be authorized or required to countersign such new certificate or
certificates a bond, in such sum as they may direct, and with such surety or
sureties, as they may direct, as indemnity against any claim that may be made
against them or any of them on account of or in connection with the alleged

the capital stock of the Corporation, in respect of which a transfer agent or
transfer clerk and/or registrar shall have been designated, shall be valid
unless countersigned by such transfer agent or transfer clerk and/or
registered by such registrar. The board may also make such additional rules
and regulations as it may deem expedient concerning the issue, transfer and
