(b) The Company represents and agrees that, unless it obtains the prior consent of the Underwriter, it has not made and will not, make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 of the Rules and Regulations unless the prior written consent of the Underwriter has been received (each, a “Permitted Free Writing Prospectus”);provided that the prior written consent of the Underwriter hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectuses included inSchedule II hereto. The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, comply with the requirements of Rules 164 and 433 of the Rules and Regulations applicable to any Issuer Free Writing Prospectus, including the requirements relating to timely filing with the Commission, legending and record keeping and will not take any action that would result in the Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) of the Rules and Regulations a free writing prospectus prepared by or on behalf of such Underwriter that such Underwriter otherwise would not have been required to file thereunder.

(c) If at any time when a Prospectus relating to the Securities is required to be delivered under the Securities Act, any event occurs or condition exists as a result of which the Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or the Registration Statement, as then amended or supplemented, would include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading, or if for any other reason it is necessary at any time to amend or supplement any Registration Statement or the Prospectus to comply with the Securities Act or the Exchange Act, the Company will promptly notify the Underwriter, and upon the Underwriter’s request, the Company will promptly prepare and file with the Commission, at the Company’s expense, an amendment to the Registration Statement or an amendment or supplement to the Prospectus that corrects

- 24 -

such statement or omission or effects such compliance and will deliver to the Underwriter, without charge, such number of copies thereof as the Underwriter may reasonably request. The Company consents to the use of the Prospectus or any amendment or supplement thereto by the Underwriter.

(d) If the General Disclosure Package is being used to solicit offers to buy the Securities at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriter, it becomes necessary to amend or supplement the General Disclosure Package in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or to make the statements therein not conflict with the information contained or incorporated by reference in the Registration Statement then on file and not superseded or modified, or if it is necessary at any time to amend or supplement the General Disclosure Package to comply with any law, the Company promptly will either (i) prepare, file with the Commission (if required) and furnish to the Underwriter and any dealers an appropriate amendment or supplement to the General Disclosure Package or (ii) prepare and file with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the General Disclosure Package so that the General Disclosure Package as so amended or supplemented will not, in the light of the circumstances under which they were made, be misleading or conflict with the Registration Statement then on file, or so that the General Disclosure Package will comply with law.

(e) If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or will conflict with the information contained in the Registration Statement, Pricing Prospectus or Prospectus, including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof and not superseded or modified or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Company has promptly notified or will promptly notify the Underwriter so that any use of the Issuer Free Writing Prospectus may cease until it is amended or supplemented and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus in reliance upon, and in conformity with, written information furnished to the Company by the Underwriter specifically for inclusion therein, which information the parties hereto agree is limited to the Underwriter’s Information (as defined inSection 17).

(i) To endeavor to qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Underwriter shall reasonably request and will continue such qualifications in effect so long as required for distribution of the Securities;provided,however, that the Company shall not be obligated to qualify or register as a foreign corporation or as a dealer in securities or to take an action that would subject it to general service of process in any such jurisdiction or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(j) To make generally available to the Company’s security holders and to the Underwriter as soon as practicable an earnings statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the date of this Agreement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

- 26 -

delivery of Ordinary Shares or such other securities, in cash or otherwise;provided,however, that the above shall not apply to (i) the sale of the Securities in this offering, the sale of the F3 Securities, or the issuance by the Company of the Underlying Securities upon the conversion of the Securities or the F3 Securities, (ii) the issuance of Ordinary Shares or options to purchase Ordinary Shares, or issue Ordinary Shares upon exercise of options, pursuant to any stock option, stock bonus or other stock plan or arrangement described in the Registration Statement, General Disclosure Package and Prospectus, but only if the holders of such shares, options, or shares issued upon exercise of such options, agree in writing not to sell, offer, dispose of or otherwise transfer any such shares or options during such Lock-up Period without the prior written consent of LCM (which consent may be withheld at the sole discretion of LCM) or (iii) file one or more registration statements on Form S-8 or amendments thereto relating to the issuance of Ordinary Shares or the issuance and exercise of options to purchase Ordinary Shares granted under the employee benefit plans of the Company existing on the date of the Prospectus or any amendment to or replacement of such plan.

The Underwriter covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) of the Rules and Regulations a free writing prospectus prepared by or on behalf of the Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

9.INDEMNITY AND CONTRIBUTION.

This indemnity agreement is not exclusive and will be in addition to any liability which the Company might otherwise have and shall not limit any rights or remedies which may otherwise be available at law or in equity to each Underwriter Indemnified Party.

- 29 -

(b) The Underwriter shall indemnify and hold harmless the Company and 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 (collectively, the “Company Indemnified Parties,” and each a “Company Indemnified Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which such Company Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, a 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 furnished to the Company by the Underwriter specifically for use therein, which information the parties hereto agree is limited to the Underwriter’s Information as defined inSection 17, and shall reimburse the Company for any legal or other expenses reasonably incurred by such party in connection with investigating or preparing to defend or defending against or appearing as third party witness in connection with any such loss, claim, damage, liability, action, investigation or proceeding, as such fees and expenses are incurred. Notwithstanding the provisions of thisSection 9(b), in no event shall any indemnity by the Underwriter under thisSection 9(b) exceed the total compensation received by the Underwriter in accordance with this Agreement.

(c) Promptly after receipt by an indemnified party under thisSection 9 of notice of the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under thisSection 9 notify such indemnifying party in writing of 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 thisSection 9 except to the extent it has been materially prejudiced by such failure; and,provided, further, that the failure to notify an indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under thisSection 9. If any such 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 of such action with counsel reasonably satisfactory to the indemnified party (which counsel shall not, except with the written consent of the indemnified party, be counsel to the indemnifying party). After notice from the indemnifying party to the indemnified party of its election to assume the defense of such action, except as provided herein, the indemnifying party shall not be liable to the indemnified party underSection 9 for any legal or other expenses subsequently incurred by the indemnified party in connection

- 30 -

with the defense of such action other than reasonable costs of investigation;provided, however, that any indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense of such action but the fees and expenses of such counsel (other than reasonable costs of investigation) shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized in writing by the Company in the case of a claim for indemnification underSection 9(a) or LCM in the case of a claim for indemnification underSection 9(b), (ii) such indemnified party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party within a reasonable period of time after notice of the commencement of the action or the indemnifying party does not diligently defend the action after assumption of the defense, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of (or, in the case of a failure to diligently defend the action after assumption of the defense, to continue to defend) such action on behalf of such indemnified party and the indemnifying party shall be responsible for legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action;provided, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties (in addition to any local counsel), which firm shall be designated in writing by LCM if the indemnified parties under thisSection 9 consist of any Underwriter Indemnified Party or by the Company if the indemnified parties under thisSection 9 consist of any Company Indemnified Parties. Subject to thisSection 9(c), the amount payable by an indemnifying party underSection 9 shall include, but not be limited to, (x) reasonable legal fees and expenses of counsel to the indemnified party and any other expenses in investigating, or preparing to defend or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any action, investigation, proceeding or claim, and (y) all amounts paid in settlement of any of the foregoing. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of judgment with respect to any pending or threatened action or any claim whatsoever, in respect of which indemnification or contribution could be sought under thisSection 9 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party in form and substance reasonably satisfactory to such indemnified party from all liability arising out of such action or claim and (ii) 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. Subject to the provisions of the following sentence, no indemnifying party shall be liable for settlement of any pending or threatened action or any claim whatsoever that is effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with its written consent, if its consent has been unreasonably withheld or delayed

- 31 -

or if there be a judgment for the plaintiff in any such matter, 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. In addition, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated herein effected without its written consent if (i) such settlement is entered into more than forty-five (45) days after receipt by such indemnifying party of the request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(d) If the indemnification provided for inSections9(a) or9(b) is unavailable or insufficient to hold harmless an indemnified party underSection 9(a) orSection 9(b), then each indemnifying party under such section shall, in lieu of indemnifying such indemnified party, contribute to the amount paid, payable or otherwise incurred by such indemnified party as a result of such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof), as incurred, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the indemnifying party on the one hand and the indemnified party or parties on the other hand from the offering of the Securities, or (ii) if the allocation provided by clause (i) of thisSection 9(d) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) of thisSection 9(d) but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party or parties on the other with respect to the statements, omissions, acts or failures to act which resulted in such loss, claim, damage, expense or liability (or any action, investigation or proceeding 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 the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Underwriter 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 on the one hand or the Underwriter on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement, omission, act or failure to act;provided that the parties hereto agree that the written information furnished to the Company by the Underwriter for use in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, consists solely of the Underwriter’s Information as defined inSection 17. The Company and the Underwriter agree that it would not be

- 32 -

just and equitable if contributions pursuant to thisSection 9(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 in thisSection 9(d). The amount paid or payable by an indemnified party as a result of the loss, claim, damage, expense, liability, action, investigation or proceeding referred to above in thisSection 9(d) shall be deemed to include, for purposes of thisSection 9(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding. Notwithstanding the provisions of thisSection 9(d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public 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, act or alleged act or failure to act or alleged failure to act. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in thisSection 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(e) The indemnity and contribution provisions contained in thisSection 9 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Underwriter, any person controlling the Underwriter or any affiliate of the Underwriter, the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

10.TERMINATION. The Underwriter may terminate this Agreement by notice given by the Underwriter to the Company if (1) after the execution and delivery of this Agreement and prior to the Closing Date, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT or the NASDAQ Global Market, or minimum or maximum prices or maximum range for prices shall have been established on any such exchange or such market by the Commission, by such exchange or market or by any other regulatory body or governmental authority having jurisdiction, (ii) trading of any securities of the Company shall have been suspended or materially limited on any exchange or in any over-the-counter market, (iii) a material disruption in commercial banking, securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York, Delaware or California authorities or (v) there shall have occurred any outbreak or escalation of national or international hostilities or an act of terrorism, or the United States shall have become engaged in hostilities, or there shall have been a declaration of a national emergency or war by the United States or any change in financial markets, or any change in United States or international economic, political or financial conditions or any calamity or crisis that, in the judgment of the Underwriter, is material and

- 33 -

adverse and which, singly or together with any other event specified in thisSection 10, makes it, in the judgment of the Underwriter, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the General Disclosure Package or the Prospectus, (2) any of the events described inSections 5(d),5(e) and5(f) shall have occurred or (3) the Underwriter shall decline to purchase the Securities for any reason permitted under this Agreement.

If this Agreement shall be terminated by the Underwriter because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, or if the Underwriter shall decline to purchase the Securities for any reason permitted under this Agreement, the Company will reimburse the Underwriter for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by the Underwriter in connection with this Agreement or the offering contemplated hereunder.

11.EFFECTIVENESS. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

The information in this Pricing Term Sheet supplements the Preliminary Prospectus Supplement and supersedes the information in the Preliminary Prospectus Supplement to the extent it is inconsistent with the information in the Preliminary Prospectus Supplement.

Issuer:	Vantage Drilling Company
Ticker / Exchange for common stock:	VTG / NYSE MKT
Title of securities:	7.875% Senior Convertible Notes due 2042 (the “notes”)
Aggregate principal amount offered:	$56,500,000 aggregate principal amount of notes, consisting of $50,000,000 principal amount of notes in the underwritten offering and $6,500,000 principal amount directly placed to F3 Capital. The completion of the underwritten offering is not conditioned on the concurrent F3 Capital Placement.
Maturity date:	September 1, 2042, unless earlier converted, repurchased or redeemed
Interest rate:	7.875% per annum, accruing from August 21, 2012
Public offering price:	100% per note
Interest payment dates:	Each March 1 and September 1, beginning on March 1, 2013
Reference price:	$1.70, the last reported sale price of the Issuer’s common stock on the NYSE MKT on August 13, 2012
Initial conversion rate:	476.1905 shares of the Issuer’s common stock per $1,000 aggregate principal amount of notes
Initial conversion price:	Approximately $2.10 per common stock of the Issuer

Redemption date:	The notes will be subject to redemption by the Issuer at its option on or after September 1, 2015 and before September 1, 2017 if the volume weighted average price of the Issuer’s ordinary shares is greater than or equal to 125% of the applicable conversion price for at least 20 trading days during any 30 consecutive trading period ending within five trading days prior to the notice of redemption. In addition, the Issuer may redeem the notes at any time on or after September 1, 2017. In each case the redemption purchase price will be equal to 100% of the principal amount of the notes being redeemed, plus accrued and unpaid interest to the redemption date.
Repurchase dates:	The notes will be subject to repurchase by the Issuer at the option of holders on September 1, 2015 and on September 1, 2017 for cash at a price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest to the repurchase date.
Mandatory Conversion at the Option of the Issuer:	The notes will be subject to mandatory conversion at the applicable conversion rate at the Issuer’s option on or before September 1, 2015 if the volume weighted average price of our ordinary shares is greater than or equal to 150% of the applicable conversion price for at least 20 trading days during any 30 consecutive trading day period ending within five trading days prior to the notice of conversion. If the Issuer effects such a mandatory conversion, it will provide in addition to the consideration otherwise due upon conversion a Conversion Make Whole Payment.
Termination of Trading Repurchase Right of Holders:	The notes will be subject to purchase by the Issuer, in whole or in part, for cash at the option of holders upon the occurrence of specified termination of trading events at a purchase price equal to 100% of the principal amount of the notes being purchased, plus accrued and unpaid interest to the purchase date.
Use of proceeds:	The Issuer estimates that the net proceeds from the underwritten portion of the offering of the notes will be approximately $48.1 million, after deducting the underwriters’ discount and estimated offering expenses. The Issuer will not receive cash proceeds from F3 Capital for the $6,500,000 principal amount of notes that will be issued in exchange for a portion of the principal of the loan note dated July 30, 2010 issued by the Issuer to F3 Capital.
	The Issuer intends to use the net cash proceeds from this offering to fund capital expenditures and working capital needs as well as general corporate purposes.

2

Commissions and discounts:	The underwriter has advised the Issuer that they propose to initially offer the notes at a price of 100% of the principal amount of the notes, plus accrued interest from the settlement date of the notes, if any. After the initial public offering, the public offering price, concession and discount may be changed.
	The following table shows the public offering price, underwriting discount and proceeds before expenses to the Issuer with regards to the underwritten portion of the offering:

	Per Note
Public offering price	$	1,000
Underwriting discounts and commissions	$	28
Proceeds, before expenses, to Issuer	$	972

Sole underwriter:	Lazard Capital Markets LLC
Relationships:	From time to time in the ordinary course of business, the underwriter and its respective affiliates have engaged in and/or may in the future engage in commercial banking, financial advisory, derivatives and/or investment banking transactions with the Issuer and its subsidiaries and other affiliates for which they have received or will receive customary fees and compensation.
Trade date:	August 14, 2012
Settlement date*:	(T+5) on August 21, 2012
*       We expect delivery of the notes will be made against payment therefor on or about August 21, 2012, which is the fifth business day following the date of pricing of the notes (such settlement being referred to as “T+5”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing of the notes or the next succeeding business day will be required, by virtue of the fact that the notes initially will settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisers
CUSIP/ISIN:	CUSIP number: G93205 AA3 ISIN number: KYG93205AA31
Ranking:	The notes will be general unsecured, senior obligations of the Issuer, ranking equally in right of payment with all of its senior unsecured indebtedness, and will be senior in right of payment to its indebtedness that is expressly subordinated to the notes, if any. The notes will be structurally subordinated to all of the Issuer’s indebtedness, including liabilities and commitments of its subsidiaries and will be effectively junior to its secured debt to the extent of the assets securing such debt.
Capitalization:	The following table replaces the table set forth under “Capitalization” on page S-26 of the Preliminary Prospectus Supplement:

(a) Reflects the application of $6,500,000 of principal amount under the F3 Capital Note as consideration for $6,500,000 of notes in the F3 Capital Placement. The completion of the F3 Capital Placement and the underwritten offering are not conditioned on the other. Closing of the F3 Capital Placement is subject to final acceptance by F3 Capital of the offering price and customary closing conditions. As a result of the application of $6,500,000 of the F3 Capital Note as consideration for $6,500,000 of notes in the F3 Capital Placement, the Issuer will recognize a charge of approximately $2,593,000.

(b) In accordance with ASC 470-20, convertible debt that may be wholly or partially settled in cash is required to be separated into a liability and an equity component, such that interest expense reflects the issuer’s nonconvertible debt interest rate. Upon issuance, a debt discount is recognized as a decrease in debt and an increase in equity. The debt component accretes up to the principal amount over the expected term of the debt. ASC 470-20 does not affect the actual amount that we are required to repay, and the amount shown in the table above for the notes, is the aggregate principal amount of the notes, without reflecting the debt discount or fees and expenses that we are required to recognize or the increase in paid in capital.

b. Each Subsidiary has been duly incorporated as an exempted company with limited liability and is validly existing and in good standing under the laws of the Cayman Islands and has full power and authority under its memorandum and articles of association to own and operate its property and to conduct its business as described in the Registration Statement. All of the issued shares of each Subsidiary have been duly and validly authorised and issued, are fully paid and non assessable and, based solely on our review of the Registers of Members, legal title to such shares is held, directly or indirectly, by the Company.

c. The Company has full power and authority under its memorandum and articles of association to enter into, execute and perform its obligations under the Transaction Documents.

d. The execution and delivery of the Transaction Documents by the Company and the performance of its obligations thereunder (including the issuance of the Notes and the Underlying Securities upon Conversion thereof) do not conflict with or result in a breach of any of the terms or provisions of the memorandum and articles of association of the Company or any law, public rule or regulation applicable to the Company in the Cayman Islands currently in force.

e. The execution, delivery and performance of the Transaction Documents have been authorised by and on behalf of the Company and, assuming such Transaction Documents have been executed and unconditionally delivered by a duly authorised Proper Officer (as defined in the Minutes) of the Company, such Transaction Documents have been duly executed and delivered on behalf of the Company and constitute the legal, valid and binding obligations of the Company enforceable in accordance with their terms.

f. The Notes have been duly authorised by the Company and when the Notes are signed in facsimile or manually by a Proper Officer (as defined in the Minutes) on behalf of the Company and, if appropriate, authenticated in the manner set forth in the Indenture and delivered against due payment therefor will be duly executed, issued and delivered and will constitute the legal, valid and binding obligations of the Company enforceable in accordance with their respective terms.

g. The Underlying Securities to be issued upon Conversion of the Notes have been duly authorised and when the Underlying Securities are issued in accordance with the articles of association of the Company and entered as fully paid on the Register of Members of the Company, the Underlying Securities will be duly issued as fully paid and non-assessable.

h. No authorisations, consents, approvals, licences, validations or exemptions are required by law from any governmental authorities or agencies or other official bodies in the Cayman Islands in connection with:

(a) the execution or delivery of the Transaction Documents;

(b) the enforcement of the Transaction Documents;

(c) payments made under, or pursuant to, the Transaction Documents; or

(d) the performance by the Company of its obligations under the Transaction Documents.

The Cayman Islands currently have no form of income, corporate or capital gains tax and no estate duty, inheritance tax or gift tax.

j. The courts of the Cayman Islands will observe and give effect to the choice of the law of the State of New York as the governing law of the Transaction Documents.

k. The obligations of the Company under the Transaction Documents will rank at least pari passu with all its other present and future unsecured obligations (other than those preferred by law).

l. The appointment by the Company in the jurisdictions specified in the Transaction Documents of an agent to accept service of process in the jurisdictions specified in the Transaction Documents is legal, valid and binding on the Company assuming the same is true under the governing law of the Transaction Documents.

m. Based solely on our search of the Register of Writs and Other Originating Process and the Register of Appeals (together, the “Court Registers”) maintained by the Clerk of the Court of the Grand Court of the Cayman Islands and by the Registrar of the Court of Appeal of the Cayman Islands respectively from the date of incorporation of the Company to August , 2012 (the “Litigation Search”), the Court Registers disclosed no writ, originating summons, originating motion, petition, counterclaim nor third party notice (“Originating Process”) nor any amended Originating Process pending before the Grand Court of the Cayman Islands nor any appeal pending before the Court of Appeal, in which the Company is a defendant or respondent.

n. Although there is no statutory enforcement in the Cayman Islands of judgments obtained in the State of New York, a judgment obtained in such jurisdiction will be recognised and enforced in the courts of the Cayman Islands at common law, without any re-examination of the merits of the underlying dispute, by an action commenced on the foreign judgment debt in the Grand Court of the Cayman Islands, provided such judgment:

(a) is given by a foreign court of competent jurisdiction;

(b) imposes on the judgment debtor a liability to pay a liquidated sum for which the judgment has been given;

(c) is final;

(d) is not in respect of taxes, a fine or a penalty; and

(e) was not obtained in a manner and is not of a kind the enforcement of which is contrary to natural justice or the public policy of the Cayman Islands.

o. It is not necessary to ensure the legality, validity, enforceability or admissibility in evidence of the Transaction Documents that any document be filed, recorded or enrolled with any governmental authority or agency or any official body in the Cayman Islands.

p. The statements made in the Prospectus Supplement under the heading “Material Cayman Islands Tax Considerations” are correct in so far as such statements are summaries of or relate to Cayman Islands law.

q. The articles of association of the Company do not entitle any shareholder of the Company to any pre-emptive right or other similar rights to subscribe for the shares of the Company or to any pre-emptive right or other similar rights to subscribe for the Notes.

r. None of Lazard Capital Markets LLC, as underwriter, or the holders of the Notes will be required to be licenced, qualified, or otherwise entitled to carry on business in the Cayman Islands in order to enforce their respective rights under the Transaction Documents, or as a consequence of the execution, delivery and performance of the Transaction Documents, or the issue of the Notes.

s. None of the parties to the Transaction Documents (other than the Company) is or will be treated as resident, domiciled or carrying on or transacting business in the Cayman Islands solely by reason of the negotiation, preparation or execution of the Transaction Documents.

t. There is no exchange control legislation under Cayman Islands law and accordingly there are no exchange control regulations imposed under Cayman Islands law.

Ladies and Gentlemen:

The undersigned understands that Lazard Capital Markets LLC (“LCM”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Vantage Drilling Company, a Cayman Islands exempted company (the “Company”), providing for the offering (the “Offering”) by LCM, as underwriter (the “Underwriter”), of $50,000,000 aggregate principal amount of the Company’s Convertible Senior Notes due 2042 (the “Securities”) pursuant to a registration statement (the “Registration Statement”) filed with the Securities and Exchange Commission.

To induce the Underwriter that may participate in the Offering to continue their efforts in connection with the Offering, the undersigned hereby agrees that, without the prior written consent of LCM, it will not, directly or indirectly, during the period (the “Lock-up Period”) commencing on the date hereof and ending 90 days after the date of the final prospectus relating to the Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, any ordinary shares of the Company, par value $0.001 (the “Ordinary Shares”) or any securities convertible into or exercisable or exchangeable for Ordinary Shares, (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Ordinary Shares, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Ordinary Shares or such other securities, in cash or otherwise, or (3) publicly disclose the intention to do any of the foregoing. The foregoing sentence shall not apply to (a) transactions relating to shares of Ordinary Shares or other securities acquired in open market transactions after the completion of the Offering,provided that no filing under Section 17(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be voluntarily made in connection with subsequent sales of Ordinary Shares or other securities acquired in such open market transactions, (b) transfers of Ordinary Shares or any security convertible into Ordinary Shares as a bona fide gift;provided that in the case of any transfer or distribution pursuant to clause (b), (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this

letter and (ii) no filing under Section 17(a) of the Exchange Act, reporting a reduction in beneficial ownership of Ordinary Shares, shall be required or shall be voluntarily made during the Lock-up Period, (c) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Ordinary Shares,provided that such plan does not provide for the transfer of Ordinary Shares during the Lock-up Period or (d) sales of Ordinary Shares to cover tax obligations for vesting of grants made pursuant to the Company’s Amended and Restated 2007 Long-Term Incentive Plan. In addition, the undersigned agrees that, without the prior written consent of LCM, it will not, during the Lock-up Period, make any demand for or exercise any right with respect to, the registration of any Ordinary Shares or any security convertible into or exercisable or exchangeable for Ordinary Shares. 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 Ordinary Shares except in compliance with the foregoing restrictions.

If (i) during the last 17 days of the Lock-up Period the Company issues an earnings release or material news or a material event relating to the Company occurs; or (ii) prior to the expiration of the Lock-up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-up Period, then the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

The undersigned shall not engage in any transaction that may be restricted by this agreement during the 34-day period beginning on the last day of the initial restricted period unless the undersigned requests and receives prior written confirmation from the Company or LCM that the restrictions imposed by this agreement have expired.

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

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 LCM.

If (i) the Underwriting Agreement terminates or is terminated prior to the payment for and delivery of the Securities, (ii) either LCM, on the one hand, or the Company, on the other hand, have advised the other in writing, prior to the execution of the Underwriting Agreement, that it has determined not to proceed with the Offering, (iii) the Company notifies the undersigned in writing that it does not intend to proceed with the Offering, withdraws the Registration Statement or deregisters all of the securities covered by the Registration Statement or (iv) the Underwriting Agreement is not executed on or prior to             , 2012, then this Lock-Up Agreement shall terminate immediately upon such date and be of no further force and effect.

Very truly yours,
