purchaser, not misleading or (ii) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representative may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make

the statements therein, not misleading, (ii) or any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) or any Time of Sale Information (including any Time of Sale Information that has subsequently been amended), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement 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 to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the information contained in the fifth paragraph on the cover relating to the sale of the Shares and commissions; the information contained in the third paragraph under the caption “Underwriting” relating to market making, the information contained in the fourth paragraph under the caption “Underwriting” relating to the sale of the Shares, and the information contained in the eleventh and twelfth paragraphs under the caption “Underwriting” relating to stabilization and market making by the Underwriters.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to

notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary or (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. The Indemnifying Person 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 Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person 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 the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person 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 Company, on the one hand, and the Underwriters, on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, 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, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Shares. The relative fault of the Company, on the one hand, and the Underwriters, on the other, 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 by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 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 paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares 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 Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, 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 any of the New York Stock Exchange, the Nasdaq Global Market or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

10. Defaulting Underwriter. (a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non defaulting Underwriters or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date does not exceed 10% of the aggregate number of Shares to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date exceeds 10% of the aggregate amount of Shares to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Shares and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing this Agreement; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and

expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Shares under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (vi) the cost of preparing stock certificates; (vii) the costs and charges of any transfer agent and any registrar; (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (x) all expenses and application fees related to the listing of the Shares on the Exchange.

(b) If (i) this Agreement is terminated pursuant to Section 9(ii), (ii) the Company for any reason fails to tender the Shares for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Shares by reason of any failure, refusal or inability on the part of the Company to perform any undertaking or satisfy any condition of this Agreement or to comply with any of the terms hereof, unless such failure to satisfy said condition or to comply with said terms be due to the default or omission of the Underwriters, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Shares from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Shares and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “significant subsidiary” has the meaning set forth in Rule 1-02 of Regulation S-X under the Exchange Act.

Form of Opinion of Counsel for the Company

1. The Company is a corporation under the DGCL, with corporate power and authority to own its properties and to conduct its business as described in the Registration Statement, the Preliminary Prospectus and the Prospectus. With your consent, based solely on certificates from public officials, such counsel shall confirm that the Company is validly existing and in good standing under the laws of the State of Delaware and is qualified to do business in the State of Texas.

2. The Shares to be issued and sold by the Company pursuant to the Underwriting Agreement have been duly authorized by all necessary corporate action of the Company and, when issued to and paid for by you and the other Underwriters in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid and nonassessable and free of preemptive rights arising from the Governing Documents or the DGCL.

3. The execution, delivery and performance of the Underwriting Agreement have been duly authorized by all necessary corporate action of the Company, and the Underwriting Agreement has been duly executed and delivered by the Company.

4. The execution and delivery of the Underwriting Agreement and the issuance and sale of the Shares by the Company to you and the other Underwriters pursuant to the Underwriting Agreement do not on the date hereof:

(i) violate the Company’s Governing Documents; or

(ii) result in the breach of or a default under any of the Specified Agreements set forth on Schedule I; or

Xxx-A-1-1

(iii) violate the DGCL or any federal or Texas statute, rule or regulation applicable to the Company; or

(iv) require any consents, approvals, or authorizations to be obtained by the Company from, or any registrations, declarations or filings to be made by the Company with, any governmental authority under the DGCL or any federal or Texas statute, rule or regulation applicable to the Company on or prior to the date hereof that have not been obtained or made.

5. The Registration Statement has become effective under the Act. With your consent, based solely on a telephonic confirmation by a member of the Staff of the Commission, such counsel shall confirm that no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings therefor have been initiated by the Commission. The Preliminary Prospectus has been filed in accordance with Rule 424(b) under the Act, the Prospectus has been filed in accordance with Rule 424(b) and 430B under the Act.

6. The Registration Statement, at the time it became effective on February 27, 2012, including the information deemed to be a part thereof pursuant to Rule 430B under the Act, and the Prospectus, as of its date, each appeared on their face to be appropriately responsive in all material respects to the applicable form requirements for registration statements on Form S-3 under the Act and the rules and regulations of the Commission thereunder; it being understood, however, that such counsel need express no view with respect to Regulation S-T or the financial statements, schedules, or other financial data, included in, incorporated by reference in, or omitted from, the Registration Statement or the Prospectus. For purposes of this paragraph, such counsel may assume that the statements made in the Registration Statement and the Prospectus are correct and complete.

7. Each of the Incorporated Documents, as of its respective filing or effective date, appeared on its face to be appropriately responsive in all material respects to the applicable form requirements for reports on Forms 10-K and 8-K, as the case may be, under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission thereunder; it being understood, however, that such counsel need express no opinion with respect to Regulation S-T or the financial statements, schedules, or other financial data, included in, incorporated by reference in, or omitted from such reports and proxy statement. For purposes of this paragraph, such counsel may assume that the statements made in the Incorporated Documents are correct and complete.

8. The statements in the Preliminary Prospectus and the Prospectus under the caption “Description of capital stock,” insofar as they purport to constitute a summary of the terms of the Common Stock, are accurate descriptions or summaries in all material respects.

Xxx-A-1-2

9. The statements in the Preliminary Prospectus and Prospectus under the caption “Material United States federal income tax consequences to non-United States holders of our common stock,” insofar as such statements purport to constitute summaries of United States federal income tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the matters described therein in all material respects.

10. Based solely on a certificate of an officer of the Company as to factual matters, the Company is not, and after giving effect to the sale of the Shares in accordance with the Underwriting Agreement and the application of the proceeds as described in the Prospectus under the caption “Use of Proceeds,” will not be required to be registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

In addition, such counsel shall state that, in the course of acting as special counsel to the Company in connection with the preparation by the Company of the Registration Statement, the Preliminary Prospectus, the Pricing Information Annex and the Prospectus, such counsel reviewed the Registration Statement, the Preliminary Prospectus, the Pricing Information Annex, and the Prospectus, and the Incorporated Documents, and participated in conferences and telephone conversations with officers and other representatives of the Company, the independent public accountants for the Company, the Underwriters representatives, and the Underwriters counsel, during which conferences and conversations the contents of the Registration Statement, the Preliminary Prospectus, the Pricing Information Annex, and the Prospectus (and portions of certain of the Incorporated Documents) and related matters were discussed, and that such counsel also reviewed and relied upon certain corporate records and documents, letters from counsel and accountants, and oral and written statements of officers and other representatives of the Company and others as to the existence and consequence of certain factual and other matters.

Based on such counsel’s participation, review and reliance as described above, such counsel shall advise the Underwriters that, although they are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in, or incorporated by reference in, the Registration Statement, the Preliminary Prospectus, the Pricing Information Annex, the Prospectus, or the Incorporated Documents (except to the extent expressly provided in numbered paragraphs 8 and 9 above), and have not made an independent check or verification thereof (except as aforesaid), no facts came to such counsel’s attention that caused such counsel to believe that:

Xxx-A-1-3

•

the Registration Statement, at the time it became effective on February 27, 2012, including the information deemed to be a part of the Registration Statement pursuant to Rule 430B under the Act (together with the Incorporated Documents at that time), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

•

the Preliminary Prospectus, as of February 27, 2012 (together with the Incorporated Documents at that date), when taken together with the Pricing Information Annex, contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

•

the Prospectus, as of its date or as of the Closing Date, (together with the Incorporated Documents at those dates), contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that such counsel need express no belief with respect to the financial statements, schedules, or other financial data included or incorporated by reference in, or omitted from, the Registration Statement, the Preliminary Prospectus, the Pricing Information Annex, the Prospectus, or the Incorporated Documents.

Form of Opinion of In-House Counsel for the Company

(a) Based on certificates from officers of the Company, public officials and the Subsidiaries, each of the Subsidiaries has been duly organized and is validly existing as a corporation, limited partnership or limited liability company in good standing under the laws of the jurisdiction of its incorporation or organization, with corporate, limited partnership or limited liability power and authority to own or lease its properties and conduct its business as described in the Registration Statement, the Time of Sale Information and the Prospectus; the Company and each of the Subsidiaries are duly qualified to transact business in all jurisdictions in which the conduct of their business requires such qualification and in which the failure to qualify would have a Material Adverse Effect.

(b) To my knowledge, there are no material legal or governmental proceedings pending or threatened against the Company or any of its Subsidiaries, except as set forth in the Registration Statement, the Time of Sale Information and the Prospectus or as would not reasonably be expected to have a Material Adverse Effect.

(c) The execution and delivery of the Underwriting Agreement by the Company, the issuance and sale of the Shares by the Company pursuant to the Underwriting Agreement and the consummation by the Company of the transactions contemplated by the Underwriting Agreement, the Registration Statement, the Time of Sale Information and the Prospectus on the date hereof do not result in the breach of or a violation of, or imposition of any lien, charge or encumbrance upon any property or asset of the Company or any Subsidiary pursuant to the terms of any indenture, contract, lease, mortgage, deed or trust or other agreements to which the Company or any Subsidiary is a party or bound or to which its or their property is subject, that is filed as an exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2011 (the “Material Agreements”).

(d) The statements in the Registration Statement, the Time of Sale Information and the Prospectus incorporated by reference from Item 3 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2011, insofar as such statements constitute a summary of documents referred to therein or matters of law, accurately summarize in all material respects the information required to be set forth thereunder under the Securities Act with respect to such documents and matters.

Xxx-A-2-1

In rendering the opinions in paragraph (c) insofar as they require interpretation of the Material Agreements, with your consent, (i) I have assumed that all courts of competent jurisdiction would enforce the Material Agreements in accordance with their plain meaning but would apply the internal laws of the State of California without giving effect to any choice of law provisions contained therein or any choice of law principles which would result in the application of the internal laws of any jurisdiction other than the State of California, (ii) to the extent that any questions of legality or legal construction have arisen in connection with my review, I have applied the internal laws of the State of California in resolving such questions, (iii) I have assumed that the Company will comply with the terms of the Underwriting Agreement, and (iv) I express no opinion with respect to any matters which would require me to perform a mathematical calculation or make a financial or accounting determination. I advise you that certain of the Material Agreements are governed by other laws, that such laws may vary substantially from the law assumed to govern for purposes of this opinion, and that this opinion may not be relied upon as to whether or not a breach or default would occur under the law actually governing such Material Agreements.

Exh B-1

shares permitted to be sold by the undersigned pursuant to this proviso to be determined by the Company in its sole discretion. In addition, the undersigned agrees that, without the prior written consent of Xxxxxx Xxxxxxx on behalf of the Underwriters, it will not, during the period ending 60 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. Notwithstanding the foregoing, the undersigned may transfer the undersigned’s Common Stock (a) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (b) to any trust, limited partnership or other entity for the direct or indirect benefit of the undersigned or the immediate family member or spouse of the undersigned, provided that the trustee of the trust or the authorized officer of the partnership or other entity agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, and (c) to any third party granted an interest in the will or under the laws of descent, provided that the donee agrees to be bound in writing by the restrictions set forth herein.

This Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.
