Dear Sirs and Mesdames:

     Transocean Inc., a Cayman Islands company (the “Selling Stockholder”), proposes to sell to the several underwriters named in Schedule I hereto (the “Underwriters”) an aggregate of 12,000,000 shares of the Class A common stock (par value $0.01 per share) (the “Firm Shares”) of TODCO, a Delaware corporation (the “Company”).

     The Selling Stockholder also proposes to sell to the several Underwriters not more than an additional 1,310,000 shares of the Class A common stock (par value $0.01 per share) of the Company (the “Additional Shares”) if and to the extent that you, as managers of the offering, shall have determined to exercise, on behalf of the Underwriters, the right to purchase such shares of common stock granted to the Underwriters in Section 3 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares.” The shares of Class A common stock (par value $0.01 per share) of the Company to be outstanding after giving effect to the sales contemplated hereby are hereinafter referred to as the “Common Stock.”

     The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement, including a prospectus, relating to the Shares. The registration statement as amended at the time it became effective, including the

information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A under the Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Registration Statement”; the prospectus in the form first used to confirm sales of Shares including any documents incorporated therein or deemed to be incorporated therein is hereinafter referred to as the “Prospectus.” If the Company has filed an abbreviated registration statement to register additional shares of Common Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement.

     1. Representations and Warranties of the Company. The Company represents and warrants to and agrees with each of the Underwriters that:

     (a) The Registration Statement (excluding for this purpose any Rule 462 Registration Statement) has become effective; no stop order suspending the effectiveness of the Registration Statement is in effect, and no proceedings for such purpose are pending before or threatened by the Commission.

     (b) (i) The Registration Statement, when it became effective, did not contain and, as amended or supplemented, if applicable, will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Registration Statement and the Prospectus comply and, as amended or supplemented, if applicable, will comply in all material respects with the Securities Act and the applicable rules and regulations of the Commission thereunder and (iii) the Prospectus does not contain and, as amended or supplemented, if applicable, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that the representations and warranties set forth in this paragraph (b) do not apply to statements or omissions in the Registration Statement or the Prospectus based upon information furnished to the Company in writing by any Underwriter through you expressly for use therein.

     (c) There has not occurred any material adverse change, or any development involving a prospective material adverse change, in the general affairs, management, financial position, stockholders’ equity or result of operations, or in the earnings, business or operations of the Company and its subsidiaries, taken as a whole, from that set forth in the Prospectus (exclusive of any amendments or supplements thereto subsequent to the date of this Agreement).

     (d) The preliminary prospectus supplement dated May 11, 2005 filed pursuant to Rule 424 under the Securities Act, complied when so filed in all

material respects with the Securities Act and the applicable rules and regulations of the Commission thereunder.

     (e) The statements set forth in the Company’s registration statement on Form 8-A filed with the Commission on February 5, 2004 under the caption “Description of Registrant’s Securities to be Registered” incorporated into the Prospectus, insofar as they purport to constitute a summary of the terms of the Company’s capital stock and the statements set forth in the Prospectus under the caption “Underwriters”, insofar as they purport to describe the provisions of the laws and documents referred to therein, are accurate, complete and fair in all material respects.

     (f) To the knowledge of the Company, Ernst & Young LLP, who have certified certain financial statements of the Company, are independent public accountants as required by the Securities Act and the rules and regulations of the Commission thereunder.

     (g) Each of the Company and its significant subsidiaries (as defined in Rule 1-02(w) forming part of Regulation S-X under the Securities Act, except that the determination of whether a subsidiary is a significant subsidiary shall be made as of the date hereof or as of the Closing Date, as applicable, rather than as of the end of the relevant fiscal year) (each, a “Significant Subsidiary”) has been duly organized and is validly existing as a corporation in good standing under the laws of its jurisdiction of incorporation, with power and authority (corporate and other) to own its properties and conduct its business as described in the Prospectus, and has been duly qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties, or conducts any business, so as to require such qualification, except where the failure to be so qualified would not have a material adverse effect on the general affairs, management, financial position, stockholders’ equity or results of operations of the Company and its subsidiaries considered as one enterprise (a “Material Adverse Effect”).

     (h) This Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and binding agreement of the Company.

described in the Prospectus and except to the extent that any failure of such shares to be free and clear of all liens, encumbrances, equities or claims would not, individually or in the aggregate, have a Material Adverse Effect.

     (k) The Shares are duly authorized for listing on the New York Stock Exchange, subject to notice of issuance.

     (l) The execution and delivery by the Company of, and the performance by the Company of its obligations under, this Agreement will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the properties or assets of the Company or any of its subsidiaries is subject, nor will such action result in any violation of the provisions of the Certificate of Incorporation or Bylaws of the Company or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its subsidiaries or any of their properties, except, in each case other than with respect to such Certificate of Incorporation or Bylaws, for any such conflict, breach, violation or default which would not, individually or in the aggregate, have a Material Adverse Effect and would not impair the Company’s ability to perform its obligations hereunder or have any material adverse effect upon the consummation of the transactions contemplated hereby; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the performance by the Company of its obligations under this Agreement, except for such consents, approvals, authorizations, registrations or qualifications as (i) have been, or will have been prior to the Closing Date, obtained under the Securities Act or the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or (ii) may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Shares by the Underwriters.

     (n) Other than as set forth in the Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its

-4-

subsidiaries is the subject which, if determined adversely to the Company or any of its subsidiaries, would, individually or in the aggregate, have a Material Adverse Effect; and, to the best of the Company’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

     (o) The Company is not, and after giving effect to the offering and sale of the Shares, will not be, an “investment company”, as such term is defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”).

     (q) Except as set forth in the Prospectus, there are no costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) which would, singly or in the aggregate, have a Material Adverse Effect.

     (r) Except as described in the Prospectus, there are no contracts, agreements or understandings between the Company and any person granting such person the right to require the Company to file a registration statement under the Securities Act with respect to any securities of the Company or to require the Company to include such securities with the Shares registered pursuant to the Registration Statement.

     (s) The Company and its Significant Subsidiaries have good and marketable title to all real property and good and marketable title to all personal property owned by them which is material to the business of the Company and its subsidiaries, taken as a whole, in each case free and clear of all liens, encumbrances and defects except such as are described in the Prospectus or such as do not materially affect the value of such property and would not, individually or in the aggregate, have a Material Adverse Effect; and any real property and

-5-

buildings held under lease by the Company or its Significant Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as do not interfere with the use made and proposed to be made of such property and buildings by the Company or its subsidiaries, in each case except as described in the Prospectus and except as would not, individually or in the aggregate, have a Material Adverse Effect.

     (v) The Company and its subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent in the businesses in which they are engaged (such businesses are as described in the Prospectus); and the Company has no reason to believe that the Company will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its businesses at a cost that would not have a Material Adverse Effect on the Company and its subsidiaries, taken as a whole, except as described in the Prospectus.

     3. Agreements to Sell and Purchase. The Selling Stockholder hereby agrees to sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees, severally and not jointly, to purchase from the Selling Stockholder at $20.1925 a share (the “Purchase Price”), the number of Firm Shares (subject to such

-8-

     On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Selling Stockholder agrees to sell to the Underwriters the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly, up to 1,310,000 Additional Shares at the Purchase Price.

     The restrictions contained in the preceding paragraph shall not apply to (i) the Shares, (ii) the issuance by the Company of shares of Common Stock upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof, (iii) transactions by any person other than the Company relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the offering of the Shares, (iv) any distribution of shares of Common Stock by the Selling Stockholder to the holders of its ordinary shares by means of a distribution or exchange offer, (v) grants of Common Stock or other securities pursuant to employee benefit plans in existence as of the date hereof or (vi) private sales by the Selling Stockholder of Common Stock or other securities in which the purchaser agrees to be bound by the

     5. Payment and Delivery. Payment for the Firm Shares to be sold by the Selling Stockholder shall be made to the Selling Stockholder in Federal or other funds immediately available in Houston, Texas against delivery of such Firm Shares for the respective accounts of the several Underwriters at 10:00 a.m., Houston time, on May 18, 2005.

-22-

          (b) The Selling Stockholder agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent but only to the extent such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Selling Stockholder furnished to the Company in writing by the Selling Stockholder expressly for use therein; provided, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased Shares, or any person controlling such Underwriter, if a copy of the Prospectus (as then amended or supplemented if the Company has furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Shares to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities; provided, further, that the liability of the Selling Stockholder pursuant to this subsection (b) shall not exceed the product of the number of Shares sold by the Selling Stockholder, including any Additional Shares, and the public offering price per share of the Shares as set forth in the Prospectus.

-23-

          (d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a), 9(b) or 9(c) hereof, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing (but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection, except to the extent that indemnifying party suffers actual prejudice as a result of such failure) and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, the Selling Stockholder, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or the Selling Stockholder within the meaning of either such Section. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by Citigroup Global Markets Inc. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company or the Selling Stockholder, such firm shall be designated in writing by the Company and the Selling Stockholder. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

-24-

          (e) To the extent the indemnification provided for in Section 9(a), 9(b) or 9(c) hereof is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, except to the extent (but only to the extent) that the indemnifying party suffers actual prejudice as a result of any failure by the indemnified party to notify the indemnifying party of any action, proceeding or investigation as contemplated by subsection (d) of this Section 9, each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by Section 9(e)(i) hereof is not permitted by applicable law, or if the indemnified party failed to give the notice required under subsection (d) above, then, except to the extent (but only to the extent) that the indemnifying party suffers actual prejudice as a result of any failure by the indemnified party to notify the indemnifying party of any action, proceeding or investigation as contemplated by subsection (d) of this Section 9, in such proportion as is appropriate to reflect not only the relative benefits referred to in Section 9(e)(i) hereof but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company or the Selling Stockholder on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Selling Stockholder and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company or the Selling Stockholder on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Stockholder or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

          (f) The Company, the Selling Stockholder and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(e) hereof. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such

-25-

indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

          (g) The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company and the Selling Stockholder contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, the Selling Stockholder or any person controlling the Selling Stockholder, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares; provided, however, that if this Agreement shall be terminated pursuant to Section 10(i), (iii), (iv), or (v) or the second paragraph of Section 11 hereof, the Company and the Selling Stockholder shall have no liability to you other than as set forth in Section 11 hereof.

     10. Termination. The Underwriters may terminate this Agreement by notice given by Citigroup Global Markets Inc. to the Company and the Selling Stockholder, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, the New York Stock Exchange or the Nasdaq National Market, (ii) trading of any securities of the Company shall have been suspended on the New York Stock Exchange, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any adverse change in financial markets or any calamity or crisis that, in the reasonable judgment of Citigroup Global Markets Inc., is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the reasonable judgment of Citigroup Global Markets Inc., impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Prospectus.

     11. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

-26-

     If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 11 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased, and arrangements satisfactory to you, the Company and the Selling Stockholder for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholder. In any such case either you, the Company or the Selling Stockholder shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company or the Selling Stockholder to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company or the Selling Stockholder shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder, but the Company and the Selling Stockholder shall then be under no further liability to you except as provided in Sections 1, 8 and 9.

-27-

     12. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

     13. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

     14. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

Dear Sirs and Mesdames:

     The undersigned understands that Citigroup Global Markets Inc. (“Citigroup”) and the several underwriters named in Schedule I to the Underwriting Agreement (as defined below), including Citigroup (the “Underwriters”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with TODCO, a Delaware corporation (the “Company”), and its stockholder, Transocean Inc., a Cayman Islands company, providing for the public offering (the “Public Offering”) by the several Underwriters of 13,310,000 shares (the “Shares”) of the Class A common stock (par value $0.01 per share) of the Company (the “Common Stock”).

     To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Citigroup on behalf of the Underwriters, he will not, during the period commencing on the date hereof and ending 45 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”), (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in the Public Offering or open market transactions after the completion of the Public Offering, (b) transfers of shares of Common Stock or any security convertible into Common Stock as a bona fide gift or gifts and (c) transfers of Common Stock or any security convertible into

Common Stock by will or intestacy; provided that in the case of any transfer or distribution pursuant to clause (b), (i) each donee or distributee shall execute and deliver to Citigroup a duplicate form of this Lock-up Letter and (ii) no filing by any party (donor, donee, transferor or transferee) under Section 16(a) of the Securities Exchange Act of 1934, as amended, shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5). In addition, the undersigned agrees that, without the prior written consent of Citigroup on behalf of the Underwriters, he will not, during the period commencing on the date hereof and ending 45 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s share of Common Stock except in compliance with the foregoing restrictions.

     The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

     Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.
