and Stock Awards granted under Section 6 of the Plan (including deferred rights

(b)  Options granted to a Participant pursuant to Section 7 of this Plan from
and after August 1, 2004 and prior to April 27, 2006 shall be granted under the

granted to a Participant pursuant to Section 7 hereof from and after August 1,
2004 and prior to April 27, 2006.

(c)  Options granted to a Participant pursuant to Section 7 of this Plan from
and after April 27, 2006 shall be granted under the Astec Industries, Inc. 2006
Incentive Plan, or any subsequent equity incentive plan approved by the
Company’s shareholders for the grant of options to its employees and directors
(the “Current Incentive Plan”).  The terms contained in the Current Incentive
Plan are incorporated into and made a part of this Plan with respect to such
Options and such Options shall be governed by and construed in accordance with
the Current Incentive Plan.  In the event of any actual or alleged conflict
between the provisions of the Current Incentive Plan and the provisions of this
Plan, the provisions of the Current Incentive Plan shall be controlling and
determinative with respect to Options granted to a Participant pursuant to
Section 7 hereof from and after April 27, 2006.”

2.  The Plan is hereby amended by adding a new Section 11 to read as follows:

“11.  Internal Revenue Code Section 409A.

(a)  It is intended that the payments and benefits provided under the Plan shall
either be exempt from the application of, or comply with, the requirements of
Section 409A of the Internal Revenue Code.  The Plan shall be construed in a
manner that effects such intent.  Nevertheless, the tax treatment of the
benefits provided under the Plan is not warranted or guaranteed.  Neither the
Company, its affiliates nor their respective directors, officers, employees or
advisers shall be held liable for any taxes, interest, penalties or other
monetary amounts owed by any Participant or other taxpayer as a result of the
Plan.

(b)  Notwithstanding anything in the Plan to the contrary, to the extent that
any amount or benefit that would constitute non-exempt “deferred compensation”
for purposes of Section 409A of the Internal Revenue Code would otherwise be
payable or distributable, or a different form of payment (e.g., lump sum or
installment) would be effected, under the Plan by reason of the occurrence the
Participant’s termination of service as a director, such amount or benefit will
not be payable or distributable to the Participant, and/or such different form
of payment will not be effected, by reason of such circumstance unless the
circumstances giving rise to such termination of service meet any description or
definition of “separation from service” in Section 409A of the Internal Revenue
Code and applicable regulations (without giving effect to any elective
provisions that may be available under such definition).  If this provision
prevents the payment or distribution of any amount or benefit, such payment or
distribution shall be made on the next earliest payment or distribution date or
event specified that is permissible under Section 409A of the Internal Revenue
Code.  If this provision prevents the application of a different form of payment
of any amount or benefit, such payment shall be made in the same form as would
have applied absent such designated event or circumstance.

(c) No Option granted under the Plan shall provide for any feature for the
deferral of compensation other than the deferral of recognition of income until
the exercise or disposition of the Option.”

Each subsequent Section shall be re-numbered accordingly.

3.           The Plan shall be amended by deleting Section 14 in its entirety
and replacing it with the following:

“The Plan shall remain in effect until terminated by the Committee.”

4.           The Plan shall be amended by deleting Section 16 in its entirety
and replacing it with the following:

5.           Except as expressly amended hereby, the terms of the Plan, as
previously amended, shall be and remain unchanged and the Plan as amended hereby
shall remain in full force and effect.

IN WITNESS WHEREOF, the Company has caused this Amendment to be executed by its
duly authorized representative on the day and year first above written.
