purposes set forth in the Maverick Tube Corporation (“Company”) 2004 Omnibus
Incentive Plan (the “Plan”), you have been granted by the Compensation Committee
of the Board of Directors of the Company (the “Committee”) the opportunity to

(the "Stock"), subject to the agreement between the Company and Optionee as
follows:
 
 1.  Grant
of Option . As of
the Grant Date specified above, and subject to the terms and provisions set
forth herein, the Company hereby grants to Optionee an option ("Option") to
purchase up to **NUMBER
OF SHARES WRITTEN OUT (#OF SHARES) shares** of Stock
(the "Option Shares"), at the purchase price specified in Section
2.
 
 2.  Price . The per
share price of each share of Stock purchased pursuant to the exercise of this
Option ("Exercise Price") shall be **DOLLAR
AND CENTS** . The
Exercise Price shall be payable to the Company in full at the time of exercise:
(i) in cash or by check payable and acceptable to the Company; (ii) by tendering
to the Company shares of Stock owned by Optionee having an aggregate Market
Value Per Share (as defined in the Plan) as of the date of exercise and tender
that is not greater than the full Exercise Price for the shares with respect to
which the Option is being exercised and by paying any remaining amount of the
Exercise Price as provided in (i) above; or (iii) subject to the approval of the
Committee and to such instructions as the Committee may specify, at Optionee's
written request the Company may deliver certificates for the number of Option
Shares for which the Option is being exercised to a broker for sale on behalf of
Optionee, provided that: (A) Optionee has irrevocably instructed such broker to
remit directly to the Company on Optionee's behalf the full amount of the
Exercise Price from the proceeds of such sale; and (B) Such transaction is not,
in the judgment of the Company, prohibited by law. In the event Optionee elects
to make payment as allowed under clause (ii) above, the Committee may, upon
confirming that Optionee owns the number of shares of Stock being tendered,
authorize the issuance of a new certificate for the number of shares being
acquired pursuant to the exercise of the Option less the number of shares being
tendered upon the exercise and return to Optionee (or not require surrender of)
the certificate for the shares of Stock being tendered upon the exercise.
Payment instruments will be received subject to collection.

same proportions as their ownership immediately prior to such Transaction; (B)

Securities of such Resulting Corporation, and (C) at

Securities of such corporation ("New Other Voting Securities") is then owned
beneficially, directly or indirectly, by substantially all of the beneficial
owners of the Stock and the combined voting power of all outstanding Other
Voting Securities of the Company in substantially the same proportions as their
ownership of such securities of the Company immediately prior thereto; (II) no
Person other than the Company and any employee benefit plan or related trust of
the Company or of such corporation then beneficially owns 35% or more of the New
Stock or the New Other Voting Securities; and (III) at
