$[_________] Date: May 14, 2003

CUSIP #: 04623#AB1

FOR VALUE RECEIVED, ASTEC INDUSTRIES, INC. ("Parent") and ASTEC FINANCIAL SERVICES, INC. ("Financial"; Parent and Financial are each referred to herein as an "Obligor" and collectively referred to as the "Obligors"), hereby, jointly and severally, unconditionally promise to pay to the order of [__________________] (hereafter, together with any holder set forth hereof, called "Holder"), at the offices of the Holder and using the payment instructions set forth on Schedule 1 attached hereto, or at such other place as the Holder may designate in writing to the Obligors, in lawful money of the United States of America, and in immediately available funds, the principal sum of [__________________________] DOLLARS ($[__________]), together with interest on the principal balance from time to time outstanding hereunder (computed on the basis of a 360-day year of twelve 30-day months) from the date hereof until paid in full at a per annum rate equal to 8.935%.

Repayment

The principal of this Note, and all accrued interest thereon, shall be due and payable in full in a single installment on October 31, 2008.

Interest shall accrue on any amount past due hereunder (whether at the stated maturity or any accelerated maturity hereunder) at a rate equal to 10.935% ("Overdue Interest"). All such interest shall be due and payable on demand.

Redemption

Notwithstanding the face amount of this Note, the Obligors may redeem each $1000 of outstanding principal of this Note by delivering to the Holder in cash an amount (the "Redemption Amount") equal to the product of (i) the principal amount of the Note to be redeemed multiplied by (ii) the percentage (the "Redemption Percentage") set forth below corresponding to the date on which such redemption shall occur (the "Redemption Date") in accordance with the table below:

Redemption Date Redemption Percentage

On or before October 31, 2003 40.0%

On or before October 31, 2004 60.0%

On or before October 31, 2005 70.0%

On or before October 31, 2006 80.0%

On or before October 31, 2007 90.0%

The Obligors shall pay all interest accrued on the principal amount of the Note so redeemed on the Redemption Date. In the event the Obligors elect to redeem all or a portion of this Note, the Obligors shall give the Holder written notice (a "Notice of Redemption") of such election not less than 15 calendar days but not more than 30 calendar days prior to the proposed Redemption Date at the address of such Holder set forth on Schedule 1 attached hereto. The Notice of Redemption shall set forth the amount of principal of this Note to be redeemed, the Redemption Date, the applicable Redemption Percentage and the Redemption Amount. The delivery of such a Notice of Redemption shall be irrevocable and the applicable Redemption Amount, together with all accrued but unpaid interest on the principal amount of the Note to be redeemed to the Redemption Date, shall be due and payable on the Redemption Date. The redemption of a principal amount of this Note in the manner specified above, together with the payment of all accrued interest on the principal amount so redeemed to the Redemption Date, shall constitute a full and final satisfaction of such principal and accrued interest thereon. Notwithstanding the foregoing, in the event that at any time prior to the Redemption Date, the Holder chooses to exercise the conversion rights set forth hereinbelow for all or any portion of the principal amount of this Note, then such conversion shall take precedence over a redemption hereunder and the provisions of this redemption section shall only apply as to that portion of the principal amount included in the Redemption Notice and not so converted.

Conversion

Subject to the provisions of this Section, at the option of the Holder, at any time, the principal amount of this Note, plus any accrued but unpaid interest thereon, may be converted into shares of the Parent's common stock, $.20 par value per share (the "Common Stock") at the Conversion Price, determined as provided below.

The conversion of principal of this Note shall be based (i) if the conversion occurs on or prior to October 31, 2003, on the corresponding Redemption Amount with respect to the amount of such principal so to be converted that would otherwise be payable by the Obligors had such amount of principal been redeemed by the Obligors plus accrued interest to the date of conversion, all in accordance with the table set forth above and the period such conversion takes place and (ii) if the conversion occurs at any time after October 31, 2003, on the principal amount due upon maturity of this Note plus accrued interest to the date of such conversion. Accordingly, upon conversion of all or a portion of this Note, the Holder shall be entitled to receive one share of Common Stock for each Eight Dollars and Seventeen Cents ($8.17) ("Conversion Price") of (x) in the case of (i) above, the Redemption Amount that would otherwise be payable by the Obligors had the Obligors elected to redeem the Note at the time of conversion plus accrued but unpaid interest through the Conversion Date and (y) in the case of (ii) above, the principal amount that will be due upon maturity of this Note plus accrued but unpaid interest through the Conversion Date. No fractional shares of Common Stock shall be issued upon the conversion of this Note. Instead of a fraction of a share of Common Stock that would otherwise be issuable upon conversion of this Note, the Parent shall pay a cash adjustment in respect of such fraction of a share of Common Stock in an amount equal to the same fractional interest of the Conversion Price. The Parent shall pay all taxes and other charges in respect of the issuance of shares of Common Stock to the Holder upon such conversion.

The Conversion Price shall be adjusted for any stock dividends, stock splits, subdivisions, reclassification, combinations or similar events by multiplying such Conversion price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately prior to such event and the denominator shall be the number of shares outstanding immediately after giving effect to such event. An adjustment made pursuant to this paragraph shall become effective immediately after the date of such event. Promptly after any adjustment in the Conversion Price pursuant to this paragraph, the Parent shall give written notice to the Holder of the Conversion Price following such adjustment, together with a schedule of computations of such adjustment and confirmation from the Parent's auditors of such adjustment.

In the event of any capital reorganization of the Parent, any reclassification of the stock of the Parent (other than a change in par value or from par value to no par value or from no par value to par value), or any consolidation or merger of the Parent, this Note shall after such reorganization, reclassification, consolidation, or merger be convertible into the kind and number of shares of stock or other securities or property of the Parent or of the corporation resulting from such consolidation or surviving such merger to which the Holder of the number of shares of Common Stock deliverable (immediately prior to the time of such reorganization, reclassification, consolidation or merger) upon conversion of such Note would have been entitled upon such reorganization, reclassification, consolidation or merger. The provisions of this clause shall similarly apply to successive reorganizations, reclassifications, consolidations or mergers.

If the Parent shall propose to take any action of the types described in the paragraph above, the Parent shall give notice to the Holder which notice shall specify the record date, if any, with respect to any such action and the date on which such action is to take place. Such notice shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the Conversion Price and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon the occurrence of such action or deliverable upon conversion of the Notes. In the case of any action which would require the fixing of a record date, such notice shall be given at least 20 days prior to the date so fixed, and in case of all other action, such notice shall be given at least 30 days prior to the taking of such proposed action. Failure to give such notice, or any defect therein, shall not affect the legality or validity of any such action.

In order to exercise the right of conversion pursuant to this Section, the Holder shall give five days written notice to the Parent that the Holder has elected to convert this Note. Following receipt of such conversion notice, the Holder shall surrender this Note to the Parent at its principal office. Upon receipt of the Note so surrendered by the Holder, the Parent shall issue and deliver to the Holder the certificate or certificates or other document evidencing the shares of Common Stock issuable on such conversion (and, in the event less than the entire principal amount of the Note is redeemed, a new Note in a principal amount equal to the unredeemed portion and containing the substantially identified terms to this Note). Such conversion shall be deemed to have been effected at the close of business on the date of surrender of the Note to the Parent (the "Conversion Date") and the Holder shall be deemed to have become a holder of record of the shares of Common Stock of the Parent into which a principal amount of this Note was converted.

Accredited Investor Representation

By receipt of the Note, the Holder represents and warrants to the Parent that the Holder (a) is an "accredited investor" as that term is defined in Rule 501(a) of Regulation D as promulgated under the Securities Act, (b) alone or together with its advisors is an investor experienced in the evaluation of businesses similar to the Parent's business, and has such knowledge and experience in financial, business and other relevant matters as to be competent and fully capable of examining all the merits, risks and other aspects of the contemplated investment on its own and to make an informed decision with respect thereto, (c)  has the ability to bear the economic risks of this investment which could include the loss of some or all of its investment and has sufficient other assets such that the loss of all its investment in the Parent would not have a material adverse effect on its financial condition or adversely affect its ability to maintain its present operations and (d) has been afforded prior to the date hereof the opportunity to ask questions of, and to receive answers from, the Parent and its representatives and has received from the Parent all other information concerning the contemplated investment that it has requested.

Distributions

So long as any portion of this Note remains unpaid or not converted, the Obligors will not, and will not permit any of their Subsidiaries (as defined in the Subordination Agreement) to, at any time declare or make, or incur any liability to declare or make, any Distribution.

"Distribution" means:

2. the redemption or acquisition of such stock or of warrants, rights or other options to purchase capital stock of Parent (except when solely in exchange for such stock and except pursuant to employment agreements and arrangements entered into in the ordinary course of business with non-executive level employees) unless made, contemporaneously, from the net proceeds of a sale of capital stock; and
3. any payment to any stockholder of either Obligor in the nature of consulting or management fees (except for compensation or consulting arrangements entered into in the ordinary course of business or otherwise approved by the disinterested members of the Board of Directors of the Parent).
