(a) The Company hereby agrees to indemnify and hold harmless the Underwriter, its affiliates, directors, officers and employees and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which the Underwriter, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto, (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 under the Securities Act) used or referred to by the Underwriter, (D) any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Stock, including any “road show” (as defined in Rule 433 under the Securities Act) not constituting an Issuer Free Writing Prospectus (“Marketing Materials”), or (E) any Blue Sky application or other document prepared or executed by the Company (or based upon any written information furnished by the Company for use therein) specifically for the purpose of qualifying any or all of the Stock under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (in the case of any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, in the light of the circumstances under which they were made) not misleading, and shall reimburse the Underwriter and each such affiliate, director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Underwriter, affiliate, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, in reliance upon and in conformity with written information concerning the Underwriter furnished to the Company through the Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability

US-DOCS\72272474.19

which the Company may otherwise have to the Underwriter or to any affiliate, director, officer, employee or controlling person of the Underwriter.

(b) The Underwriter shall indemnify and hold harmless the Company, its directors, officers and employees, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Underwriter furnished to the Company through the Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in addition to any liability that the Underwriter may otherwise have to the Company or any such director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under paragraphs (a) and (b) of this Section 8 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling

US-DOCS\72272474.19

persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 8 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel as contemplated by Section 8(a) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a), 8(b) or 8(c) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriter, on the other, from the offering of the Stock, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i)

US-DOCS\72272474.19

above but also the relative fault of the Company, on the one hand, and the Underwriter, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriter, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Company, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriter with respect to the shares of the Stock purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), in no event shall the Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by the Underwriter with respect to the offering of the Stock exceeds the amount of any damages that the 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.

(a) The Underwriter confirms and the Company acknowledges and agrees that the statements set forth on (i) the cover page regarding delivery of the Stock, and (ii) the following statements under the heading “Underwriting,” (A) the Underwriter’s participation in the sale of Stock, (B) the second paragraph under the heading “Commissions and Expenses,” and (C) the paragraphs (including the bullet points contained therein) under the heading “Stabilization and Short Positions,” in each case contained in the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning the Underwriter furnished in writing to the Company specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials.

SECTION 9. Termination. The obligations of the Underwriter hereunder may be terminated by notice given to and received by the Company prior to delivery of and payment for the Firm Stock if, prior to that time, any of the events described in Sections 7(j), 7(k) and 7(l) shall

US-DOCS\72272474.19

have occurred or if the Underwriter shall decline to purchase the Stock for any reason permitted under this Agreement.

SECTION 10. Reimbursement of Underwriter’s Expenses. If (a) the Company shall fail to tender the Stock for delivery to the Underwriter for any reason (other than by reason of a default by the Underwriter), or (b) the Underwriter shall decline to purchase the Stock for any reason permitted under this Agreement , the Company will reimburse the Underwriter for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Underwriter) incurred by the Underwriter in connection with this Agreement and the proposed purchase of the Stock, and upon demand the Company shall pay the full amount thereof to the Underwriter.

SECTION 11. Research Analyst Independence. The Company acknowledges that the Underwriter’s research analysts and research departments are required to be independent from its investment banking division and are subject to certain regulations and internal policies, and that the Underwriter’s research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of its investment banking division. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriter with respect to any conflict of interest that may arise from the fact that the views expressed by its independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by the Underwriter’s investment banking divisions. The Company acknowledges that the Underwriter is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

SECTION 12. No Fiduciary Duty. The Company acknowledges and agrees that in connection with this offering, sale of the Stock or any other services the Underwriter may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriter: (a) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriter, on the other, exists; (b) the Underwriter is not acting as advisor, expert or otherwise, to the Company, including, without limitation, with respect to the determination of the public offering price of the Stock, and such relationship between the Company, on the one hand, and the Underwriter, on the other, is entirely and solely commercial, based on arms-length negotiations; (c) any duties and obligations that the Underwriter may have to the Company shall be limited to those duties and obligations specifically stated herein; and (d) the Underwriter and its affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Underwriter with respect to any breach of fiduciary duty in connection with this offering.

SECTION 13. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

US-DOCS\72272474.19

Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 15, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

SECTION 15. Survival. The respective indemnities, representations, warranties and agreements of the Company and the Underwriter contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Stock and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

SECTION 16. Definition of the Terms “Business Day”, “Affiliate” and “Subsidiary”. For purposes of this Agreement, (a) “business day” means each Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close, and (b) “affiliate” and “subsidiary” have the meanings set forth in Rule 405 under the Securities Act.

FORM OF LOCK-UP LETTER AGREEMENT

BARCLAYS CAPITAL INC.

745 Seventh Avenue
New York, New York 10019

Ladies and Gentlemen:

The undersigned understands that you (the “Underwriter”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the Underwriter of shares (the “Stock”) of common stock, par value $0.16 2/3 per share (the “Common Stock”), of Parker Drilling Company, a Delaware corporation (the “Company”), and that the Underwriter proposes to reoffer the Stock to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriter, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of the Underwriter, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock (including, without limitation, shares of Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and shares of Common Stock that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Common Stock, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock or any other securities of the Company, or (4) publicly disclose the intention to do any of the foregoing for a period commencing on the date hereof and ending on the 60^th day after the date of the Prospectus relating to the Offering (such 60-day period, the “Lock-Up Period”).

The foregoing paragraph shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in the open market after the completion of the offering, (b) bona fide gifts, sales or other dispositions of shares of any class of the Company’s capital stock, in each case that are made exclusively between and among the undersigned or members of the undersigned’s family, or affiliates of the undersigned, including its partners (if a partnership) or members (if a limited liability company); provided

Exhibit A-1

US-DOCS\72272474.19

that it shall be a condition to any transfer pursuant to this clause (b) that (i) the transferee/donee agrees to be bound by the terms of this Lock-Up Letter Agreement (including, without limitation, the restrictions set forth in the preceding sentence) to the same extent as if the transferee/donee were a party hereto, (ii) each party (donor, donee, transferor or transferee) shall not be required by law (including without limitation the disclosure requirements of the Securities Act of 1933, as amended (the Securities Act”), and the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) to make, and shall agree to not voluntarily make, any filing or public announcement (other than in a Form 5) of the transfer or disposition prior to the expiration of the 60-day period referred to above, and (iii) the undersigned notifies the Underwriter at least two business days prior to the proposed transfer or disposition, (c) the exercise of warrants or the exercise of stock options granted pursuant to the Company’s stock option/incentive plans or otherwise outstanding on the date hereof; provided, that the restrictions set forth in this Lock-Up Letter Agreement shall apply to shares of Common Stock issued upon such exercise or conversion, (d) the establishment of any contract, instruction or plan that satisfies all of the requirements of Rule 10b5-1 (a “Rule 10b5-1 Plan”) under the Exchange Act; provided, however, that no sales of Common Stock or securities convertible into, or exchangeable or exercisable for, Common Stock, shall be made pursuant to a Rule 10b5-1 Plan prior to the expiration of the Lock-Up Period; provided further, that the Company is not required to report the establishment of such Rule 10b5-1 Plan in any public report or filing with the Commission under the Exchange Act during the Lock-Up Period and does not otherwise voluntarily effect any such public filing or report regarding such Rule 10b5-1 Plan, (e) shares of Common Stock transferred for the primary purpose of satisfying any tax or other governmental withholding obligation, through cashless surrender, with respect to an award of equity-based compensation pursuant to any incentive plan of the Company described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, (f) any demands or requests for, exercise any right with respect to, or take any action in preparation of, the registration by the Company under the Securities Act of the undersigned’s shares of Common Stock; provided that no transfer of the undersigned’s shares of Common Stock registered pursuant to the exercise of any such right and no registration statement shall be filed under the Securities Act with respect to any of the undersigned’s shares of Common Stock during the Lock-Up Period, and (g) the offer, sale or sales (which may be effected in any manner whatsoever), together with offers and sales by other officers or directors of the Company signing substantially similar lock-up letter agreements with you in connection with the Offering, of up to an aggregate of 0.1% of the Company’s shares of Common Stock on a fully diluted basis after giving effect to the Offering.

In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Company notifies the Underwriter that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive

Exhibit A-2

US-DOCS\72272474.19

termination) shall terminate or be terminated prior to payment for and delivery of the Stock, the undersigned will be released from its obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Company and the Underwriter will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

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

[Signature page follows]

Exhibit A-3

US-DOCS\72272474.19

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

Very truly yours,

US-DOCS\72272474.19

EXHIBIT B

FORM OF OPINION OF COMPANY’S COUNSEL


1.	The Company is validly existing in good standing as a corporation under the Delaware General Corporation Law (the “DGCL”) with all requisite corporate power and authority to (i) own, lease and operate its properties and conduct its business as described in the Prospectus and (ii) execute and deliver the Underwriting Agreement and to consummate the transactions contemplated thereunder.


2.	The Underwriting Agreement has been duly authorized and validly executed and delivered by the Company.


3.	The Shares have been duly authorized by the Company and, when issued and delivered to the Underwriter in accordance with the terms of the Underwriting Agreement against payment of the consideration therefor, will be validly issued, fully paid and nonassessable and free and clear of any preemptive rights under the DGCL and the Company’s Organizational Documents.

The execution and delivery of the Underwriting Agreement by the Company does not, and the performance by the Company of its obligations thereunder will not (i) violate the Company’s Organizational Documents, (ii) result in a breach or violation of any of the terms or provisions of, or constitute a default (or an event that, with notice or lapse of time or both, would constitute such a default) under, or result in the acceleration of indebtedness under, or the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company under, any Specified Agreement or (iii) violate the DGCL or any statute, rule or regulation of the United States or the State of New York that, in our experience, is normally applicable to transactions of the type contemplated by the Underwriting Agreement, other than federal or state securities laws, as to which such counsel need not express an opinion; provided that such counsel need not express an opinion as to whether the execution and delivery of the Underwriting Agreement by the Company, or the performance by the Company of its obligations thereunder, constitutes a violation or breach of, or a default under, any covenant, restriction or provision with respect to financial ratios or tests or any aspect of the financial condition or results of operations of the Company or any of its subsidiaries.

No consent, approval, authorization, order, registration, filing or qualification of or with any governmental authority is required under United States federal law or under the DGCL in connection with the execution and delivery of the Underwriting Agreement by the Company, or the performance by the Company of its obligations thereunder, except such as may have been required under applicable state securities laws or under the Securities Act, as to which such counsel need not express any opinion, and those which have been previously made or obtained.

Exhibit B-1

US-DOCS\72272474.19

The Registration Statement has been declared effective under the Securities Act; any required filing of the Prospectus, and any supplements thereto, pursuant to Rule 424(b) under the Securities Act has been made in the manner and within the period required by Rule 424(b); to our knowledge, no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted and are pending.


7.	The statements included in the Registration Statement and the Prospectus under the caption “Description of Capital Stock – Common Stock,” insofar as they purport to constitute summaries of the terms of the Common Stock, are accurate in all material respects.

The statements set forth in the Registration Statement and the Prospectus under the caption “Material U.S. Federal Income Tax Considerations for Non-U.S. Holders,” insofar as they purport to constitute a summary of United States federal income tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the United States federal income tax law and regulations or legal conclusions described therein in all material respects, subject to the assumptions and qualifications set forth therein.


9.	The Company is not, and immediately after giving effect to the offering and sale of the Shares and the application of the proceeds thereof as described in the Registration Statement and the Prospectus, will not be required to be registered as an “investment company” under the Investment Company Act of 1940, as amended.

We have reviewed the Registration Statement, the Pricing Disclosure Package and the Prospectus and have participated in conferences with officers and other representatives of the Company, with representatives of the Company’s independent registered public accounting firm and with your representatives and your counsel, at which the contents of the Registration Statement, the Pricing Disclosure Package, the Prospectus and related matters were discussed. The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Registration Statement, the Pricing Disclosure Package or the Prospectus, and we have not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the Pricing Disclosure Package and the Prospectus involve matters of a non-legal nature. Accordingly, we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Registration Statement, the Pricing Disclosure Package and the Prospectus (except to the extent stated in paragraphs 7 and 8 above). Subject to the foregoing and on the basis of the information we gained in the course of performing the services referred to above, we advise you that:


(a)	the Registration Statement, as of the latest Effective Time, the Preliminary Prospectus, as of the Applicable Time, and the Prospectus, as of its date and the date hereof, appear on their face to be appropriately responsive in all material respects

Exhibit B-2

US-DOCS\72272474.19

to the requirements of the Securities Act and the rules and regulations of the Commission thereunder; and


(b)	nothing came to our attention that caused us to believe that:

FORM OF OPINION OF GENERAL COUNSEL

The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or be in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect (as defined in the Underwriting Agreement).

Each significant subsidiary (as defined by Rule 1-02 of Regulation S-X) (each a “Significant Subsidiary”) of the Company is duly qualified as a foreign corporation, limited partnership or limited liability company, as the case may be, to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or be in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

The execution, delivery and performance of the Underwriting Agreement by the Company, the consummation of the transactions contemplated by the Underwriting Agreement and the application of the proceeds from the sale of the Shares as described under “Use of Proceeds” in the Prospectus do not and will not, (i) result in the imposition or creation of (or the obligation to create or impose) a material lien, encumbrance, equity, claim or adverse interest under any 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 or their respective properties or assets is bound, other than such as would not reasonably be expected to have a Material Adverse Effect; or (ii) result in the suspension, termination or revocation of any Material Authorization (as defined in the Underwriting Agreement) of the Company or any of its subsidiaries or any other impairment of the rights of the holder of any such Material Authorization.

To my knowledge, there are no contracts, agreements or understandings between the Company, on the one hand, and any person, on the other hand, 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 owned or to be owned by such person and to require the Company to include such securities in the securities registered pursuant to the Registration Statement or in any securities being registered pursuant to any other registration statement filed by the Company under the Securities Act.


5.	To my knowledge, there are no contracts or other documents that would be required to be described in the Pricing Disclosure Package or the Prospectus that have not been so described therein.


6.	To my knowledge, after reasonable investigation, except as set forth in the Pricing Disclosure Package and the Prospectus, there are no legal or governmental proceedings pending to which

Exhibit C-1

the Company or any of its subsidiaries is a party or of which any property or assets of the Company or any of its subsidiaries is the subject that if determined adversely to the Company and its subsidiaries could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and to my knowledge, no such proceedings are threatened by governmental authorities or others.
