ITEM 1.01       ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT
                ------------------------------------------

         (a)    Option Vesting Acceleration

         On December 29, 2005, the Board of Directors of Ameriana Bancorp (the
"Company") approved the accelerated vesting of 50,000 outstanding unvested stock
options. As a result of the accelerated vesting, these stock options, which
otherwise would have vested from time to time through August 2009, became
immediately exercisable. The acceleration included options held by directors,
executive officers and employees of the Company and its wholly owned subsidiary,
Ameriana Bank and Trust.

         All of the 50,000 stock options for which vesting will be accelerated
are "underwater" meaning that the current market price of the Company's common
stock exceeded the exercise price of the options. The Company will not incur a
charge in the fourth quarter of 2005 in connection with the acceleration.

         The acceleration of vesting was undertaken to eliminate compensation
expense that the Company would otherwise be required to recognize with respect
to these unvested stock options upon adopting Financial Accounting Standards
Board Statement No. 123 (Revised 2004), "Share-Based Payment" ("SFAS 123R").
Adoption of SFAS 123R is required on or before January 1, 2006, and will require
that compensation expense associated with stock options unvested at December 31,
2005 be recognized in the Company's consolidated statement of operations over
the remaining vesting period of the options. It is anticipated that the
accelerated vesting of these options will eliminate potential pre-tax
compensation expense recognition in future periods of approximately $23,000.

         Of the stock options for which vesting was accelerated, 28,500 options
are held by executive officers.

         (b)      Option Grants

         On December 29, 2005, pursuant to the Ameriana Bancorp 1996 Stock
Option and Incentive Plan, the Board of Directors of the Company granted the
following stock options to named executive officers of the Company:



          NAME                               TITLE                            OPTIONS GRANTED
- -------------------------    ---------------------------------------    ----------------------------
                                                                             
Jerome J. Gassen             President, Chief Executive Officer                    3,500
                             and Director
Timothy G. Clark             Executive Vice President and Chief                    3,000
                             Operating Officer
Bradley L. Smith             Senior Vice President - Treasurer and                 2,500
                             Chief Financial Officer


         Additionally, each non-employee director was granted an option to
purchase 3,500 shares of Company common stock. All of the options granted have
an exercise price of $12.43, the fair market value of the Company's common stock
on the date of grant, a ten-year term and are immediately exercisable.

         A copy of the Company's press release announcing the option grants and
the decision to accelerate outstanding options is attached hereto as Exhibit
99.1 and incorporated herein by reference.
