arise out of, are based upon or are in connection with any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum, any Issuer Written Information, any Additional Written Information, any General Solicitation, or any other written information used by or on behalf of the Issuer or the Company in connection with the offer or sale of the Securities or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuer and the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Issuer or the Company by or on behalf of any Initial Purchaser through the Representatives specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of any Initial Purchaser consists of the information described as such in Section 23 hereof. This indemnity agreement will be in addition to any liability which the Issuer and the Company may otherwise have.

(b) Each Initial Purchaser severally and not jointly agrees to indemnify and hold harmless the Issuer and the Company, each of their respective directors, officers, and each person who controls the Issuer or the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity in Section 8(a)(i), but only with reference to written information relating to such Initial Purchaser furnished to the Issuer or the Company by or on behalf of such Initial Purchaser through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity, it being understood and agreed that the only such information furnished by or on behalf of any Initial Purchaser consists of the information described as such in Section 23 hereof. This indemnity agreement will be in addition to any liability which any Initial Purchaser may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, 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 commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under Section 8(a) or (b) unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in Section 8(a) or (b). The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate

counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party in writing to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, 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. Subject to the immediately preceding sentence, an indemnifying party shall not be required to indemnify the indemnified party for any amount paid or payable by the indemnified party in the settlement of any proceeding effected without the written consent of the indemnifying party, which consent shall not be unreasonably withheld or delayed.

(d) In the event that the indemnity provided in Section 8(a), (b) or (c) is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Issuer, the Company and the Initial Purchasers severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Issuer and the Company and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Issuer or the Company on the one hand and by the Initial Purchasers on the other from the offering of the Securities; provided, however, that in no case shall any Initial Purchaser (except as may be provided in any agreement among Initial Purchasers relating to the offering of the Securities) be responsible for any amount in excess of the initial purchaser discount applicable to the Securities purchased by such Initial Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Issuer, the Company and the Initial Purchasers severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuer or the Company on the one hand and of the Initial Purchasers on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Issuer and the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses), and benefits received by the Initial Purchasers shall be deemed to be equal to the total initial purchaser discounts. Relative fault shall be determined by reference to, among other things, (i) whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Issuer or the Company on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission, and (ii) whether any loss or liability incurred by the Initial Purchasers arose from or was in connection with the Company’s or the Issuer’s performance or failure to perform under the Transaction Documents. The Issuer, the Company and the Initial Purchasers

agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 8(d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act, each affiliate of any Initial Purchaser within the meaning of Rule 405 under the Act and each director, officer, employee and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company, and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this Section 8(d).

9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser or Initial Purchasers hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the aggregate principal amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule II hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date or Settlement Date, as the case may be, shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company and any nondefaulting Initial Purchaser for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such delivery and payment (i) trading in the Company’s Ordinary Shares shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange or the NASDAQ Global Market shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the

Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Issuer, the Company and each of their respective officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

Furthermore, each of the Issuer and the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Initial Purchasers has advised or is currently advising the Company on related or other matters). Each of the Issuer and the Company agrees that it will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Initial Purchasers, or any of them, with respect to the subject matter hereof.

16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

17. Waiver of Jury Trial. The Issuer and the Company hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

18. Submission to Jurisdiction; Service of Process. Each of the Issuer and the Company hereby irrevocably and unconditionally (i) submits, for itself and for its property, to the exclusive jurisdiction of the United Stated District Court for the Southern District of New York or, if that federal court lacks subject matter jurisdiction, the Commercial Division of the Supreme Court of the State of New York sitting in New York County, and any appellate court from any thereof, in any action or proceeding arising out of or in any way relating to this Agreement or the transactions contemplated hereby, or for recognition or enforcement of any judgment, (ii) agrees that it will not assert any claim, or in any way support any suit, action or proceeding, arising out of or relating to this Agreement or the transactions contemplated hereby, or for recognition or enforcement of any judgment, other than in such courts, (iii) agrees that all suits, claims, actions or proceedings related to this Agreement or the transactions contemplated hereby shall be heard and determined only in such courts, (iv) waives, to the fullest extent it may effectively do so, the defense of inconvenient forum and (v) agrees that a final judgment of such courts shall be conclusive and may be enforced in any other jurisdiction by suit on the judgment or in any other manner provided by law. Each of the Issuer and the Company agrees that service of any process, summons, notice or document by registered mail addressed to the Issuer or the Company, respectively, c/o ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, Senior Vice President, General Counsel and Secretary, ▇ ▇▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ shall be effective service of process against the Issuer or Company, respectively, for any suit, action or proceeding relating to any dispute related to this Agreement or the transactions contemplated hereby.

19. Judgment Currency. If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder, or in connection with the transactions contemplated in this document, in dollars into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures, the parties could purchase (and remit in New York City) dollars with such other currency on the business day preceding that on which final judgment is given. Each of the Issuer’s and the Company’s obligation in respect of any sum due hereunder or in connection with the transactions contemplated in this document shall, notwithstanding any judgment in a currency other than dollars, be discharged only to the extent that on the business day following their receipt of any sum adjudged to be so due in such other currency, the parties may, in accordance with normal banking procedures, purchase (and remit in New York City) dollars with such other currency; if the dollars so purchased and remitted are less than the sum

originally due to the Initial Purchasers or any other indemnified party in dollars, each of the Issuer and the Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the relevant payee against such loss, and if the dollars so purchased exceed the sum originally due in dollars, such excess shall be remitted to the Issuer or the Company, respectively.

As a result of the increase, total debt and total capitalization as set forth under “Capitalization” in the Preliminary Offering Circular, based on the use of proceeds described therein, will increase by the amount of the increased debt. Other corresponding changes will be made where applicable throughout the Preliminary Offering Circular.

Terms used herein but not defined herein shall have the respective meanings as set forth in the Preliminary Offering Circular. All references to dollar amounts are references to U.S. dollars.

No Optional Redemption or Sinking Fund:		The Notes may not be redeemed by the Issuer except in the event of certain tax law changes as described under “Description of Notes—Optional Redemption for Changes in the Tax Laws of the Relevant Taxing Jurisdiction” in the Preliminary Offering Circular. In addition, no sinking fund is provided for the Notes, which means that the Issuer is not required to redeem or retire the Notes periodically.

Tax Redemption:		If certain changes in the law of any relevant Tax Jurisdiction (as defined in “Description of Notes—Additional Amounts” in the Preliminary Offering Circular) become effective that would impose withholding taxes on payments on the Notes, the Issuer may redeem the Notes in whole, but not in part, at a tax redemption price of 100% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the tax redemption date and all Additional Amounts (as defined in “Description of Notes” in the Preliminary Offering Circular), if any, which otherwise would be payable to the date of tax redemption. Upon the Issuer giving notice of a tax redemption, a holder may elect not to have its notes redeemed, in which case the holder would not be entitled to receive any Additional Amounts with respect to its notes after the redemption date. See “Description of Notes—Optional Redemption for Changes in the Tax Laws of the Relevant Taxing Jurisdiction” in the Preliminary Offering Circular.

Additional Amounts:		If any deduction or withholding for, or on account of, any Taxes (as defined in “Description of Notes—Additional Amounts” in the Preliminary Offering Circular) imposed by any Tax Jurisdiction will at any time be required to be made from any payments made under or with respect to the Notes, subject to certain exceptions, the Issuer will pay such Additional Amounts as may be necessary in order that the net amounts received in respect of such payments by each holder after such withholding or deduction (including any such deduction or withholding in respect of Additional Amounts) will equal the respective amounts which would have been received in respect of such payments in the absence of such withholding or deduction. See “Description of Notes—Additional Amounts” in the Preliminary Offering Circular.

Fundamental Change:		If a “fundamental change” (as defined in “Description of Notes—Fundamental Change Permits Holders to Require the Issuer to Repurchase Notes” in the Preliminary Offering Circular) occurs, subject to certain conditions, holders may require the Issuer to repurchase for cash all or any portion of their Notes in principal amounts of $1,000 or integral multiples of $1,000 thereof. The fundamental change repurchase price will be equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. See “Description of Notes—Fundamental Change Permits Holders to Require the Issuer to Repurchase Notes” in the Preliminary Offering Circular.

Use of Proceeds:		The Issuer expects the net proceeds from this offering to be approximately $728.2 million, or approximately $837.6 million if the initial purchasers exercise their option to acquire additional Notes in full, in each case after deducting the estimated initial purchaser discount and estimated offering expenses payable by the Issuer. The Issuer and Ensco expect to use the net proceeds of this offering, and any proceeds from the exercise of the initial purchasers’ option to acquire additional notes and to fund the cash portion of the purchase price of the Exchange Offer Notes in the Exchange Offers. If the Exchange Offers are not consummated or the net proceeds from this offering exceed the total cash consideration payable in the Exchange Offers, the Issuer and Ensco intend to use the remaining net proceeds from this offering to repurchase or refinance other debt of Ensco or Ensco’s subsidiaries and for general corporate purposes. See “Use of Proceeds” in the Preliminary Offering Circular.

Concurrent Exchange Offers:		Concurrently with this offering, Ensco is conducting exchange offers (the “Exchange Offers”) for any or all of the entire (i) $683.1 million outstanding principal amount of the 4.70% Senior Notes due 2021 (the “2021 Notes”) issued by Ensco, (ii) $438.0 million outstanding principal amount of the 8.50% Senior Notes due 2019 (the “2019 Notes”) issued by Pride International, Inc., a wholly owned subsidiary of Ensco (“Pride”) and (iii) $680.8 million outstanding principal amount of the 6.875% Senior Notes due 2020 issued by Pride (the “2020 Notes” and, together with the 2021 Notes and the 2019 Notes, the “Exchange Offer Notes”).

CUSIP Number (144A):		29359W AA3

ISIN (144A):		US29359WAA36

Listing:		The Issuer intends to apply for listing of the Notes on the Channel Islands Securities Exchange or another exchange selected by the Issuer.

The exact stock prices and effective dates may not be set forth in the table above, in which case:

· If the stock price is between two stock prices in the table or the effective date is between two effective dates in the table, the number of additional shares will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day year.

· If the stock price is greater than $100.00 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above as described in the Preliminary Offering Circular), no additional shares will be added to the exchange rate.

· If the stock price is less than $10.58 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above as described in the Preliminary Offering Circular), no additional shares will be added to the exchange rate.

Notwithstanding the foregoing, in no event will the exchange rate per $1,000 principal amount of Notes exceed 94.5180 Class A Ordinary Shares, subject to adjustment in the same manner as the exchange rate as set forth under “Description of Notes—Exchange Rights—Exchange Rate Adjustments” in the Preliminary Offering Circular. In addition, unless and until Ensco obtains, in accordance with the listing standards of the NYSE, shareholder approval to issue upon exchange of the notes more than 19.99% of the number of Class A Ordinary Shares outstanding as of the date of the Preliminary Offering Circular, the number of Class A Ordinary Shares, if any, deliverable upon exchange of the notes will not exceed the exchange share cap (as defined in the Preliminary Offering Circular). See “Description of Notes—Exchange Rights—Exchange Share Limitations” in the Preliminary Offering Circular.

Re: Ensco plc — Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Purchase Agreement (the “Purchase Agreement”) on behalf of the several Initial Purchasers named in such agreement (collectively, the “Initial Purchasers”), with Ensco plc, a public limited company organized under the laws of England and Wales (the “Company”) and Ensco Jersey Finance Limited, a company organized under the laws of Jersey (the “Issuer”) and a wholly-owned subsidiary of the Company, providing for the offering of the Issuer’s Exchangeable Senior Notes due 2024 (the “Securities”). The Securities are exchangeable at the option of the holders thereof. Upon exchange of $1,000 principal amount of Notes, the Issuer will deliver one exchangeable redeemable preference share of the Issuer with a par value of $0.0000001 and a paid-up value of $1,000 (an “Exchangeable Preference Share”) to be issued in accordance with the Articles and Memorandum of Association of the Issuer in effect as of the Closing Date, which Exchangeable Preference Shares will be guaranteed by the Company pursuant to a Deed Poll by the Company in favor of the holders of Exchangeable Preference Shares to be dated the Closing Date. Upon issuance, each Exchangeable Preference Share will be immediately transferred, without any action on the part of the exchanging holder, to the Company in consideration for the Company’s payment or delivery, as the case may be, to the holder thereof of (i) cash, (ii) Class A ordinary shares, par value $0.10 per share (the “Shares”), of the Company or (iii) a combination thereof, at the Company’s election.

In consideration of the agreement by the Initial Purchasers to offer and sell the Securities, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any Shares, or any

Exhibit A-1

options or warrants to purchase any Shares, or any securities convertible into, exchangeable for or that represent the right to receive Shares, whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Shares. In addition, the undersigned agrees that it will not, during the Lock-Up Period, publicly disclose the intention to engage in any of the foregoing transactions, or make any demand for or exercise any right with respect to the registration of any of the Undersigned’s Shares.

The initial Lock-Up Period will commence on the date of this Lock-Up Agreement and continue for 60 days after the public offering date set forth on the Final Memorandum used to sell the Shares (the “Public Offering Date”) pursuant to the Purchase Agreement.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares (i) 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 and provided further that no public announcement or filing under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) shall be required or voluntarily made in connection with such transfer, (ii) to any member of the immediate family of the undersigned provided that (A) the transferee or transferees agree(s) to be bound in writing by the restrictions set forth herein, (B) any such transfer shall not involve a disposition for value, and (C) no public announcement or filing under the Exchange Act shall be required or voluntarily made in connection with such transfer, (iii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that (A) the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, (B) any such transfer shall not involve a disposition for value, and (C) no public announcement or filing under the Exchange Act shall be required or voluntarily made in connection with such transfer, (iv) to an entity controlled by the undersigned provided that (A) the transferee or transferees agree(s) to be bound in writing by the restrictions set forth herein and (B) no public announcement or filing under the Exchange Act shall be required or voluntarily made in connection with such transfer, (v) pursuant to the laws of testamentary or intestate descent, (vi) to the Company for the primary purpose of paying the exercise price of options or for paying taxes (including estimated taxes) due as a result of the exercise of such options or as a result of the vesting of securities (including long-term incentive plan awards, options and warrants), in each case pursuant to any long-term incentive plan, stock ownership plan or other similar plan in effect as of the date hereof and disclosed in the Disclosure Package and the Final Memorandum; provided that no public announcement or filing under the Exchange Act shall be required or voluntarily made in connection with such transfer other than any required filing under the Exchange Act that indicates by footnote disclosure or otherwise the nature of such transfer or deemed transfer, or (vii) with the prior written consent of the Representatives on behalf of the Initial Purchasers. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood,

Exhibit A-2

marriage or adoption, not more remote than first cousin. The undersigned now has, and, except as contemplated by clauses (i) through (vii) above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. 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 Shares except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Initial Purchasers are relying upon this Lock-Up Agreement in proceeding toward consummation of the 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.

	Very truly yours,


	[Name of Shareholder]
