 <P ALIGN="CENTER" style="font-family:times;"><FONT SIZE=2><B>TRANSACTION PROPOSED&#151;YOUR VOTE IS VERY IMPORTANT  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On October&nbsp;7, 2018, Ensco&nbsp;plc ("Ensco") and Rowan Companies&nbsp;plc ("Rowan") entered into a Transaction Agreement (the "transaction agreement")
providing for the combination of the two companies. We are sending you this joint proxy statement to ask you to vote in favor of this transaction and other matters. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco
has agreed to acquire the entire issued and to be issued ordinary share capital of Rowan, which acquisition (the "transaction") is to be implemented by way of a court-sanctioned
scheme of arrangement (the "Scheme of Arrangement") to be undertaken by Rowan under Part&nbsp;26 of the UK Companies Act 2006 (the "Companies Act 2006"). If the transaction is completed, eligible
Rowan shareholders will be entitled to receive 2.215 Class&nbsp;A ordinary shares, nominal value $0.10 per share, of Ensco (the "Ensco ordinary shares") for each Class&nbsp;A ordinary share,
nominal value of $0.125 per share, of Rowan (the "Rowan ordinary shares") owned by such Rowan shareholders and subject to the Scheme of Arrangement. Following the completion of the transaction, it is
anticipated that persons who were shareholders of Ensco and Rowan immediately prior to the transaction will own approximately 61% and 39% of the combined company, respectively. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subject
to Ensco shareholder approval, Ensco also expects to effect a consolidation (being a reverse stock split under English law) of Ensco ordinary shares whereby, conditional upon and
effective immediately (or as soon as reasonably practicable) following the Scheme of Arrangement becoming effective, every four existing Ensco ordinary shares, each with a nominal value of $0.10,
shown in the register of members of Ensco following the updating of such register to give effect to the provisions of the Scheme of Arrangement will be consolidated into one Ensco ordinary share with
a nominal value of $0.40 per share (the "Reverse Stock Split"). The transaction is not conditioned on Ensco shareholder approval of the Reverse Stock Split. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco
ordinary shares are quoted on the New York Stock Exchange ("NYSE") under the symbol "ESV," and Rowan ordinary shares are quoted on the NYSE under the symbol "RDC." The market
prices of both Ensco ordinary shares and Rowan ordinary shares will fluctuate before the closing of the transaction, and you should obtain current stock price quotations for the Ensco ordinary shares
and the Rowan ordinary shares. In connection with the closing of the transaction, Ensco will be renamed Ensco Rowan&nbsp;plc. The Ensco ordinary shares will trade on the NYSE under the symbol "ERD"
or another ticker symbol selected by Ensco and Rowan prior to closing. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Your vote is very important.</B></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;We cannot complete the transaction unless the Ensco shareholders vote to approve the issuance of Ensco
ordinary shares pursuant to the transaction agreement and the Rowan shareholders vote to approve the Scheme of Arrangement and certain ancillary matters for the implementation of the transaction. The
Scheme of Arrangement also requires the sanction of the High Court of Justice of England and Wales (the "Court").
It is important that as many Rowan shareholders as possible vote on the Scheme of Arrangement so that the Court may be satisfied that there is a fair and reasonable representation of the opinion of
Rowan shareholders. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
document is a joint proxy statement for Ensco and Rowan to solicit proxies for their respective meetings of shareholders. It contains an explanatory statement in respect of the
Scheme of Arrangement (as required by the Companies Act 2006) as well as answers to frequently asked questions and a summary of the important terms of the transaction, the transaction agreement and
related matters, followed by a more detailed discussion. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>As
more particularly described in "Rowan Scheme Proposal and the Rowan Court Meeting and the Rowan General Meeting" and "The Scheme of Arrangement", the transaction is to be implemented by means of a
Court-sanctioned scheme of arrangement between Rowan and those Rowan shareholders who are Scheme Shareholders on the register of members of Rowan at the Scheme Record Time (as such terms are defined
in "The Scheme of Arrangement" as defined below) under Part&nbsp;26 of the Companies Act 2006. The procedure requires approval by Rowan shareholders at the Rowan Court meeting and the Rowan general
meeting, and the sanction of the Scheme of Arrangement by the High Court of Justice of England and Wales (the "Court"). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>The
purpose of the Scheme of Arrangement is to provide for Ensco to become the holder of the entire issued and to be issued ordinary share capital of Rowan. This is to be achieved by transferring the
Scheme Shares (as such term is defined in "The Scheme of Arrangement") held by Scheme Shareholders as at the Scheme Record Time to Ensco or its nominee, in consideration for which Ensco will issue new
Ensco ordinary shares on the basis set out in "The Scheme of Arrangement." </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>Before
the Court's sanction can be sought for the Scheme of Arrangement, the Scheme of Arrangement requires approval by the passing of the Rowan Scheme Proposal by Scheme Shareholders at the Rowan
Court meeting. The resolution must be approved by a majority in number of the Scheme Shareholders as at the Voting Record Time (as defined in "The Scheme of Arrangement") (expected to be

Rowan Scheme and Articles Amendment Proposal will be proposed as a special resolution, which means, assuming a quorum is present, such proposal will be approved if at least 75% of the votes cast are
cast in favor thereof. The Rowan Scheme and Articles Amendment Proposal will authorize the Rowan Board to implement the Scheme of Arrangement and to deal with certain ancillary matters including
necessary amendments to Rowan's articles of association. Approval of the Rowan Scheme and Articles Amendment Proposal is required for consummation of the transaction. The Transaction-Related
Compensation Proposal will be proposed as an ordinary resolution, which means, assuming a quorum is present, such proposal will be approved if a simple majority of the votes cast are in favor thereof.
Approval of the Transaction-Related Compensation Proposal is not required for the consummation of the transaction. </FONT></P>

ordinary shares. Neither the transaction agreement nor the Scheme of Arrangement contains any provision that would adjust the exchange ratio based on the fluctuations in the market value of either the
Rowan ordinary shares or Ensco ordinary shares. Because of this, the implied value of the transaction consideration which the Rowan shareholders are to receive will fluctuate between now and the

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
a UK company publicly traded on the NYSE, Ensco shareholder approval of the Ensco Transaction Consideration Proposal is subject to the shareholder approval requirements under both the
Companies Act 2006 and NYSE rules. The Ensco Transaction Consideration Proposal is being proposed as an ordinary resolution. Assuming a quorum is present, such proposal will be approved for purposes
of the Companies Act 2006 and NYSE rules if a majority of the votes cast are cast in favor thereof. Each of the Ensco Reverse Stock Split Proposal, the Ensco General Allotment Authority Proposal and
the Ensco Transaction-Related Compensation Proposal will be proposed as an ordinary resolution and, assuming a quorum is present, each such proposal will be approved if a simple majority of the votes
cast are cast in favor thereof. Each of the Ensco General Disapplication of Pre-Emptive Rights Proposal and the Ensco Specified Disapplication of Pre-Emptive Rights Proposal will be proposed as a
special resolution, which means, assuming a quorum is present, each such proposal will be approved if at least 75% of the votes cast are cast in favor thereof. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Approval
of the Ensco Transaction Consideration Proposal is required for the consummation of the transaction. Approval of the other Ensco proposals set forth above is not required in
order to consummate the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
connection with the Ensco general meeting, abstentions and broker non-votes will be considered in determining the presence of a quorum. While abstentions and broker non-votes are not
considered votes cast under the Companies Act 2006, under NYSE rules abstentions, but not broker non-votes, will be considered as votes cast for determining whether a sufficient number of votes have
been cast on a particular proposal. As a result, for purposes of determining whether the Ensco Transaction Consideration Proposal has been approved in accordance with the Companies Act 2006,
abstentions and broker non-votes will not have any effect on the outcome of the vote. With respect to NYSE rules, abstentions will have the same effect as votes cast "AGAINST" the Ensco Transaction
Consideration Proposal and broker non-votes will not have any effect on the outcome of the vote. Abstentions and broker non-votes will have no effect on the outcome of the Ensco Reverse Stock Split
Proposal, the Ensco General Allotment Authority Proposal, the Ensco Transaction-Related Compensation Proposal, the Ensco General Disapplication of Pre-Emptive Rights Proposal or the Ensco Specified
Disapplication of Pre-Emptive Rights Proposal. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To complete the transaction, Ensco and Rowan must make filings with and obtain authorizations, approvals or consents from a number of regulatory
authorities. The transaction is subject to the requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), as well as Section&nbsp;721 of Title VII of the
Defense Production Act of 1950, as amended, and other regulations pertaining to reviews by the Committee on Foreign Investment in the
United States ("CFIUS"). On October&nbsp;23, 2018, Ensco and Rowan filed a Premerger Notification and Report Form pursuant to the HSR Act with the Antitrust Division of the Department of Justice
(the "DOJ") and the Federal Trade Commission (the "FTC"). Ensco and Rowan derive revenues in other jurisdictions where antitrust clearances are or may be required, including the United Kingdom and
Saudi Arabia. Ensco and Rowan anticipate submitting filings with the General Authority for Competition for the Kingdom of Saudi Arabia and the Competition and Markets Authority of the United Kingdom
in November 2018 in order to obtain their approvals. On October&nbsp;26, 2018, Ensco and Rowan submitted a pre-filing notice to CFIUS. In addition, the new Ensco ordinary shares to be issued to
Rowan shareholders must be approved for listing on the NYSE, subject to official notice of issuance. </FONT></P>

business days) after all conditions to the completion of the transaction have been satisfied or waived, except for those conditions that are to be satisfied at closing. The Scheme of Arrangement will
be effective when an order from the Court sanctioning the Scheme of Arrangement is delivered to the Registrar of Companies in England and Wales (the "Registrar of Companies"). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco
and Rowan currently expect the completion of the transaction to occur in the first half of 2019. However, as the transaction is subject to regulatory clearance, the sanction of the
Court and the satisfaction or waiver of other conditions described in the transaction agreement, it is possible that factors outside the control of Ensco and Rowan could result in the transaction
being completed at a later time or not at all. </FONT></P>

price to the fair value of Rowan's tangible and intangible assets and liabilities at the acquisition date, with the excess purchase price, if any, being recorded as goodwill, or the excess of the fair
value of Rowan's tangible and intangible assets and liabilities at the acquisition date over the purchase price, if any, being recognized in Ensco's earnings. Under the acquisition method of
accounting, goodwill is not amortized but is tested for impairment at least annually. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following table sets forth, for the year ended December&nbsp;31, 2017 and the six months ended June&nbsp;30, 2018: (i)&nbsp;selected
per share information for Ensco on a historical basis, (ii)&nbsp;selected per share information for Rowan on a historical basis, (iii)&nbsp;unaudited selected per share information for Ensco on a
pro forma basis after giving effect to the transaction and (iv)&nbsp;unaudited selected per share information for Rowan on an equivalent pro forma basis based on the exchange ratio of 2.215 Ensco
ordinary shares for each Rowan ordinary share. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
pro forma information set forth below, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the possible
impact on the combined company that may result as a consequence of the transaction and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what
the historical results of the combined company would have been had our companies been combined during 2017 or the first six months of 2018. Upon completion of the transaction, the operating results of
Rowan will be reflected in the consolidated financial statements of Ensco on a prospective basis. You should read the data with the historical consolidated financial statements and related notes of
Ensco and Rowan contained in their respective Annual Reports on Form&nbsp;10-K for the year ended December&nbsp;31, 2017, and their respective Quarterly Reports on Form&nbsp;10-Q for the quarter
ended June&nbsp;30, 2018, all of which are incorporated by reference into this joint proxy statement. See "Where You Can Find More Information." </FONT></P>

Because the exchange ratio will not be adjusted for stock price changes and the market price of Ensco
ordinary shares will fluctuate, Rowan shareholders cannot be sure of the value of the transaction consideration they will receive.  </I></B></FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At the Scheme Effective Time, each Rowan ordinary share that is subject to the Scheme of Arrangement will be exchanged for 2.215 Ensco ordinary
shares. The exchange ratio will not change to reflect changes in the market prices of the Ensco ordinary shares and Rowan ordinary shares. The market price of Ensco ordinary shares at the time of
completion of the transaction may vary significantly from the market price of Ensco ordinary shares on the date the transaction agreement was executed, the date of this joint proxy statement and the
date of the Rowan Court meeting and Rowan general meeting. Accordingly, Rowan shareholders will not know or be able to calculate at the time of the Rowan Court meeting and Rowan general meeting the
market value of the transaction consideration they will receive upon completion of the transaction. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, the transaction might not be completed until a significant period of time has passed after the Rowan Court meeting and Rowan general meeting. Because the exchange ratio will
not be adjusted to reflect any changes in the market values of Ensco ordinary shares and Rowan ordinary shares, the market value of the Ensco ordinary shares issued, and the Rowan ordinary shares
surrendered, may be higher or lower than the values of those shares on earlier dates. Stock price changes may result from, among other things, changes in the business, operations or prospects of Ensco
or Rowan prior to or following the transaction, litigation or regulatory considerations, general business, market, industry or economic conditions and other factors both within and beyond the control
of Ensco and Rowan. Neither Ensco nor Rowan is permitted to terminate the transaction agreement solely because of changes in the market price of either company's stock. </FONT></P>

and will exercise less influence over management.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco will issue new Ensco ordinary shares to Rowan shareholders in the transaction (including Ensco ordinary shares to be issued in connection
with the vesting of certain outstanding Rowan equity awards). After giving effect to these issuances, current Ensco and Rowan shareholders are expected to hold approximately 60.5% and 39.5%,
respectively, of the outstanding Ensco ordinary shares immediately following the completion of the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Rowan

percentage ownership of Ensco that is smaller than the Rowan shareholder's and Ensco shareholder's percentage ownership of Rowan and Ensco before the Scheme Effective Time. As a result of these
reduced ownership percentages, former Rowan shareholders and current Ensco shareholders will have less influence on the management and policies of Ensco than they have prior to the transaction. </FONT></P>

The transaction agreement contains provisions that limit Ensco's and Rowan's ability to pursue alternatives
to the transaction, which could discourage a potential acquirer of Ensco or Rowan from making an alternative transaction proposal and, in certain circumstances, could require Ensco or Rowan to pay the
other party a termination fee.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under the transaction agreement, each of Ensco and Rowan is restricted from entering into alternative transactions. Unless and until the
transaction agreement is terminated, subject to specified exceptions (which are discussed in more detail in "The Transaction Agreement"), each of Ensco, Rowan and their respective subsidiaries and
representatives are prohibited from, directly or indirectly, initiating, soliciting, knowingly facilitating or knowingly encouraging (including by way of furnishing non-public information) any inquiry
in respect of, or the making of any proposal or offer that constitutes or could reasonably be expected to lead to, a takeover proposal; engaging in, continuing or otherwise participating in any
discussions or negotiations regarding, or furnishing to any other person any non-public information in connection with or for the purpose of encouraging or facilitating, a takeover proposal; or
approving, recommending, or entering into any letter of intent or similar document, agreement, commitment or agreement in principle with respect to a takeover proposal. Under the transaction
agreement, in the event of a potential change by the Ensco Board of its recommendation with respect to the Ensco Transaction Consideration Proposal or the Rowan Board of its recommendation with
respect to the Rowan Scheme Proposal and the Rowan Scheme and Articles Amendment Proposal, Ensco or Rowan, as the case may be, must provide the other party with at least four business days' prior
written notice of its intention to take such action. In addition, each party is generally required to negotiate in good faith with the other party to modify the terms of the transaction in response to
any competing acquisition proposals before the party's board of directors, as the case may be, may change, qualify, withhold, withdraw or modify its recommendation with respect to the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
the transaction agreement is terminated under specified circumstances, then Ensco or Rowan, as applicable, will be required to pay $15&nbsp;million for the other party's expenses.
In addition, if the transaction agreement is terminated under specified circumstances, Ensco or Rowan will be required to pay the other party a termination fee of $24&nbsp;million, in each case less
any expense reimbursement previously paid by Ensco or Rowan. Following payment of a termination fee, neither party will be obligated to pay any additional expenses incurred by the other party or its
affiliates. Please read "The Transaction Agreement." </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In connection with the transaction, it is possible that some customers, suppliers and other persons with whom Ensco or Rowan has business
relationships may delay or defer certain business decisions, or might decide to seek to terminate, change or renegotiate their relationship with Ensco or Rowan as a result of the transaction, which
could negatively affect Ensco's and Rowan's respective financial positions, operating results or cash flows, as well as the market price of Ensco ordinary shares and Rowan ordinary shares, regardless
of whether the transaction is completed. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
the terms of the transaction agreement, each of Ensco and Rowan is subject to certain restrictions on the conduct of its business prior to completing the transaction, which may
adversely affect its ability to execute certain business strategies. Such limitations could negatively affect each party's businesses and operations prior to the completion of the transaction.
Furthermore, the process of planning to integrate two businesses and organizations for the post-transaction period may divert management's attention and resources and could ultimately have an adverse
effect on each party. These uncertainties could cause customers, suppliers and others that deal with Ensco or Rowan to seek to change existing business relationships with such party, which in turn
could have an adverse effect on the combined company's ability to realize the anticipated benefits of the transaction. For a discussion of these restrictions, see "The Transaction
Agreement&#151;Covenants and Agreements." </FONT></P>

light of the transaction.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Uncertainty about the effect of the transaction on Ensco or Rowan employees may impair the companies' ability to attract, retain and motivate
personnel until the transaction is completed. Employee retention may be particularly challenging during the pendency of the transaction, as employees may feel uncertain about their future roles with
the combined organization. In addition, Ensco or Rowan may have to provide additional compensation in order to retain employees. If employees of Ensco or Rowan depart because of issues relating to the
uncertainty and difficulty of integration or a desire not to become employees of the combined company, the combined company's ability to realize the anticipated benefits of the transaction could be
adversely affected. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The completion of the transaction will trigger change of control or other provisions in certain agreements to which Rowan is a party. In
particular, pursuant to the indenture governing Rowan's 7.375% senior notes due 2025, Rowan will be required to make an offer to purchase all or any part of each holder's notes at an amount equal to
101% of the aggregate principal amount of such holder's notes, plus accrued and unpaid interest, if any, if there is a ratings downgrade by both Moody's Investors Service,&nbsp;Inc. ("Moody's") and
S&amp;P Global Ratings ("S&amp;P") between the public notice of the transaction and 60&nbsp;days after the consummation of the transaction (or any extended period if either Moody's or S&amp;P publicly announces
a possible downgrade). As a result, Ensco could be required to repay up to an aggregate $500.0&nbsp;million principal amount of senior notes plus approximately $5.0&nbsp;million in associated
premiums. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, the completion of the transaction will constitute a change of control under Rowan's 2018 and 2014 revolving credit facilities. As a result, the commitments will be
terminated and the outstanding balance under the revolving credit facility will be accelerated and become due and payable by Ensco in connection with the completion of the transaction. As of
June&nbsp;30, 2018, Rowan had no outstanding borrowings under its revolving credit facilities. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Additionally,
the completion of the transaction will constitute a change of control under Rowan's executive officers' change in control agreements with Rowan. These change in control
agreements provide for severance payments and benefits upon a qualifying termination that occurs within six months prior to a change in control or three years following a change in control. For
additional details, see "Rowan's Directors and Officers Have Financial Interests in the Transaction&#151;Change in Control Agreements&#151;Cash Payments and Benefits." </FONT></P>

Future changes to U.S. and foreign tax laws could adversely affect Ensco.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There is increasing uncertainty with respect to tax laws, regulations and treaties, and the interpretation and enforcement thereof that may
affect our business. The Organization for Economic Cooperation and Development ("OECD") has issued its final reports on Base Erosion and Profit Shifting, which generally focus on situations where
profits are earned in low-tax jurisdictions, or payments are made between affiliates from jurisdictions with high tax rates to jurisdictions with lower tax rates. Certain countries within which we
operate have recently enacted changes to their tax laws in response to the OECD recommendations or otherwise and these and other countries may enact changes to their tax laws or practices in the
future (prospectively or retroactively), which may have a material adverse effect on our financial position, operating results, tax requirements or cash flows. The recently enacted U.S. federal income
tax reform legislation, informally known as the Tax Cuts and Jobs Act of 2017, made substantial changes in the taxation of U.S. and multinational corporations, including a significant reduction in the
statutory corporate income tax rate, a limitation on the ability of corporations to deduct interest expense, the imposition of tax on low taxed intangible income of foreign subsidiaries, and the
imposition of a base erosion anti-abuse tax, the full impact of which is still being determined. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, our tax positions are subject to audit by UK, U.S. and other foreign tax authorities. Such tax authorities may disagree with our interpretations or assessments of the
effects of tax laws, treaties or regulations or their applicability to our corporate structure or certain transactions we have undertaken. Even if we are successful in maintaining our tax positions,
we may incur significant expenses in defending our positions and contesting claims asserted by tax authorities. If we are unsuccessful in defending our tax positions, the resulting assessments or
rulings could significantly impact our consolidated income taxes in past or future periods. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
a result of these uncertainties, as well as changes in the administrative practices and precedents of tax authorities or other matters (such as changes in applicable accounting rules)
that increase the amounts we have provided for income taxes or deferred tax assets and liabilities in our consolidated financial statements, we cannot provide any assurances as to what our
consolidated effective income tax rate will be in future periods. If we are unable to mitigate the negative consequences of any change in law, audit or other matters, this could cause our consolidated
income taxes to increase and cause a material adverse effect on our financial position, operating results or cash flows. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pursuant
to arrangements that Ensco entered into with the Depository Trust Company ("DTC"), the Ensco ordinary shares are eligible to be held in book-entry form through the facilities of
DTC. Transfers of shares held in book-entry form through DTC will not attract a charge to stamp duty or SDRT in the United Kingdom. A transfer of the shares from within the DTC system out of DTC and
any subsequent transfers that occur entirely outside the DTC system will attract a charge to stamp duty at a rate of 0.5% of any consideration, which is payable by the transferee of the shares. Any
such duty must be paid (and the relevant transfer document stamped by Her Majesty's Revenue&nbsp;&amp; Customs ("HMRC")) before the transfer can be registered in the share register of Ensco. If a
shareholder decides to redeposit shares into DTC, the redeposit will attract SDRT at a rate of 1.5% of the value of the shares. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco
has put in place arrangements with its transfer agent to require that shares held in certificated form cannot be transferred into the DTC system until the transferor of the shares
has first delivered the shares to a depository specified by Ensco so that SDRT may be collected in connection with the initial delivery to the depository. Any such shares will be evidenced by a
receipt issued by the
depository. Before the transfer can be registered in Ensco's share register, the transferor will also be required to provide the transfer agent sufficient funds to settle the resultant liability for
SDRT, which will be charged at a rate of 1.5% of the value of the shares. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Following
decisions of the European Court of Justice and the UK First-tier Tax Tribunal, HMRC has announced that it will not seek to apply a charge to stamp duty or SDRT on the issuance
of shares (or, where it is integral to the raising of new capital, the transfer of new shares) into a depositary receipt facility or clearance system provider, such as DTC. However, it is possible
that the UK government may change or enact laws applicable to stamp duty or SDRT in response to this decision, which could have a material effect on the cost of trading in Ensco's shares. Although the
UK government announced in its 2017 Autumn Budget that it will not reintroduce such charges following the UK's exit from the EU, it is possible that that position could change, that the UK's laws
relating to this may be subject to changes as a result and that such changes could have a material effect on the cost of trading in Ensco's shares. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The facilities of DTC are widely-used for rapid electronic transfers of securities between participants within the DTC system, which include
numerous major international financial institutions and brokerage firms. Currently, all trades of Ensco ordinary shares on the NYSE are cleared and settled on the facilities of DTC. The Ensco ordinary
shares are, at present, eligible for deposit and clearing within the DTC system, pursuant to arrangements with DTC whereby DTC accepted the Ensco ordinary shares for deposit, clearing and settlement
services, and Ensco agreed to indemnify DTC for any stamp duty and/or SDRT that may be assessed upon it as a result of its service as a clearance system provider for the Ensco ordinary shares.
However, DTC retains sole discretion to cease to act as a clearance system provider for the Ensco ordinary shares at any time. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
DTC determines at any time that the Ensco ordinary shares are no longer eligible for deposit, clearing and settlement services within its facilities, such shares may become ineligible

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Directors of Delaware and other U.S. corporations may issue, without further shareholder approval, shares of common stock authorized in their
certificates of incorporation that were not already issued or reserved. The business corporation laws of Delaware and other U.S. states also provide substantial flexibility in establishing the terms
of preferred stock. However, English law provides that a board of directors may only allot shares with the prior authorization of an ordinary resolution of the shareholders, which authorization must
state the maximum amount of shares that may be allotted under it and specify the date on which it will expire, which must not be more than five years from the date on which the shareholder resolution
is passed. An ordinary resolution was passed by shareholders at the Ensco 2018 Annual General Meeting to authorize the allotment of additional shares until the next annual general meeting of
shareholders (or, if earlier, at the close of business on August&nbsp;21, 2019). Subject to completion of the transaction, this authority will be replaced with a larger authority reflecting the

<P style="font-family:times;"><FONT FACE="times" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;English
law also generally provides shareholders with pre-emption rights over new shares that are issued for cash. However, it is possible, where the board of directors is generally
authorized to allot shares, to exclude pre-emption rights by a special resolution of the shareholders or by a provision in the articles of association. Such exclusion of pre-emption rights will
commonly cease to have effect at the same time as the general allotment authority to which it relates is revoked or expires. If the general allotment authority is renewed, the authority excluding
pre-emption rights may also be renewed by a special resolution of the shareholders. Special resolutions were passed, in conjunction with an allotment authority at the Ensco 2018 Annual General
Meeting, to disapply pre-emption rights until the next annual general meeting of shareholders (or, if earlier, at the close of business on August&nbsp;21, 2019). Subject to completion of the

The Ensco Articles of Association contain anti-takeover provisions.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Certain provisions of the Ensco Articles of Association have anti-takeover effects, such as the ability to issue shares under the Rights Plan
(as defined therein). These provisions are intended to ensure that any takeover or change of control of Ensco is conducted in an orderly manner, all shareholders of Ensco are treated equally and
fairly and receive an optimum price for their shares and the long-term success of Ensco is safeguarded. Under English law, it may not be possible to implement these provisions in all circumstances. </FONT></P>

Ensco is not, and following completion of the transaction the combined entity is not expected to be, subject
to the United Kingdom's Code on Takeovers and Mergers (the "Takeover Code").  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Takeover Code only applies to an offer for a public company that is registered in the United Kingdom (or the Channel Islands or the Isle of
Man) and the securities of which are not admitted to trading on a regulated market in the United Kingdom (or the Channel Islands or the Isle of Man) if the company is considered by the takeover panel
(the "Panel") to have its place of central management and control in the United Kingdom (or the Channel Islands or the Isle of Man). This is known as the "residency test." The test for central
management and control under the Takeover Code is different from that used by the UK tax authorities. Under the Takeover Code, the Panel will look to where the majority of the directors of the company
are residents for the purposes of determining where the company has its place of central management and control. Accordingly, the Panel has previously indicated that the Takeover Code does not apply
to Ensco and Ensco shareholders, therefore, do not have the benefit of the protections the Takeover Code affords, including, but not limited to, the requirement that a person who acquires an interest
in shares carrying 30% or more of the voting rights in Ensco must make a cash offer to all other shareholders at the highest price paid in the 12&nbsp;months before the offer was announced.
Following completion of the transaction, it is expected that the Takeover Code will not apply to the combined company. </FONT></P>

English law requires that Ensco meet certain additional financial requirements before declaring dividends and
returning funds to shareholders.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under English law, Ensco is only able to declare dividends and return funds to its shareholders out of the accumulated distributable reserves on
its statutory balance sheet. Distributable reserves are a company's accumulated, realized profits, so far as not previously utilized by distribution or capitalization, less its accumulated, realized
losses, so far as not previously written off in a reduction or reorganization of capital duly made. Realized profits are created through the remittance of profits of certain subsidiaries to Ensco in
the form of dividends. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;English
law also provides that a public company can only make a distribution if, among other things (a)&nbsp;the amount of its net assets (that is, the total excess of assets over
liabilities) is not less than the total of its called up share capital and non-distributable reserves and (b)&nbsp;if, and to the extent that, the distribution does not reduce the amount of its net
assets to less than that total. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco
may be unable to remit the profits of Ensco's subsidiaries in a timely or tax efficient manner. If at any time Ensco does not have sufficient distributable reserves to declare and
pay quarterly dividends, Ensco may undertake a reduction in the capital, in addition to the reduction in capital taken in 2014, to reduce the amount of share capital and non-distributable reserves and
to create a corresponding increase in distributable reserves out of which future distributions to </FONT></P>

quorum. While abstentions and broker non-votes are not considered votes cast under the Companies Act 2006, under NYSE rules abstentions, but not broker non-votes, will be considered as votes cast for
determining whether a sufficient number of votes have been cast on a particular proposal. As a result, for purposes of determining whether the Ensco Transaction Consideration Proposal has been
approved in accordance with the Companies Act 2006, abstentions and broker non-votes will not have any effect on the outcome of the vote. With respect to NYSE rules, abstentions will have the same
effect as votes cast "AGAINST" the Ensco Transaction Consideration Proposal and broker non-votes will not have any effect on the outcome of the vote. Abstentions and broker non-votes will have no

and to be issued ordinary share capital of Rowan. Holders of Ensco ordinary shares should read carefully this joint proxy statement in its entirety, including the annexes, for more detailed

which is attached as Annex&nbsp;A to this joint proxy statement, and to the detailed terms of the Scheme which are set out in "The Scheme of Arrangement." </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Accordingly,

<BR></FONT><FONT SIZE=2><B>  ENSCO PROPOSAL 2&#151;REVERSE STOCK SPLIT PROPOSAL    <BR>    </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In connection with the transaction, Ensco shareholders are also being asked to approve a consolidation (being a reverse stock split under
English law) of Ensco ordinary shares each with a nominal value of $0.10 (the "Existing Ensco Shares") whereby, conditional upon and effective immediately (or as soon as practicable) following the
Scheme of Arrangement becoming effective, every four Existing Ensco Shares shown in the register of members of Ensco following the updating of such register to give effect to the provisions of the
Scheme of Arrangement will be consolidated into one Ensco ordinary share with a nominal value of $0.40 per share (each a "Consolidated Ensco Share"). If approved, the Reverse Stock Split will affect
all Ensco shareholders (including former Rowan shareholders to whom Existing Ensco Shares have been issued in consideration for their Scheme Shares at the Scheme Effective Time) uniformly. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
a result of the Reverse Stock Split, each Ensco shareholder will own a reduced number of Ensco ordinary shares upon the implementation of the Reverse Stock Split. The Reverse Stock
Split will change the nominal value of Ensco ordinary shares from $0.10 to $0.40 per share but will not change any Ensco shareholder's percentage ownership interest in Ensco, except to the extent that
the Reverse Stock Split would result in any Ensco shareholder(s) otherwise owning a fractional share. Therefore, voting rights and other rights and preferences of the holders of Existing Ensco Shares
will not be affected by the Reverse Stock Split (other than as a result of the treatment of fractional shares described below). Consolidated Ensco Shares issued pursuant to the Reverse Stock Split
will remain fully paid and nonassessable. Ensco would effect the Reverse Stock Split simultaneously in respect of all Existing Ensco Shares. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
of the effective time of the Reverse Stock Split, Ensco will adjust and proportionately decrease the number of Ensco ordinary shares issuable in respect of equity incentive awards and
also adjust and proportionately increase the exercise price of all outstanding options. In addition, as of the effective time of the Reverse Stock Split, Ensco will adjust and proportionately decrease
the total number of Ensco ordinary shares that may be the subject of future grants under Ensco's equity incentive plans. In addition, the exchange rate under Ensco's 3.00% Exchangeable Senior Notes
due 2024 will be proportionately adjusted in accordance with the indenture governing such notes. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Reverse Stock Split will not affect the total ordinary shareholders' equity on Ensco's balance sheet. The per share earnings or losses and per share book value of Ensco will be
increased because there will be fewer Ensco ordinary shares outstanding. Prior periods' per share amounts will be recast in financial statements issued following the transaction to reflect the Reverse
Stock Split. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There
can be no assurance that Ensco will continue to pay a dividend following the consummation of the transaction. Ensco's dividend policy following the consummation of the transaction
will be at the discretion of the Board of Directors of the combined company and will depend on the combined company's profitability, liquidity, financial condition, market outlook, reinvestment
opportunities, capital requirements, restrictions and limitations in its credit facility and other debt documents and other factors and restrictions the combined company board deems relevant. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;No
fractions of Ensco ordinary shares will be issued in connection with the Reverse Stock Split. All fractions of Ensco ordinary shares resulting from the Reverse Stock Split will be
aggregated and sold in the market as soon as reasonably practicable following the date on which the Reverse Stock Split completes and the holders will receive the net proceeds of the sale (after the
deduction of the expenses of sale, without interest and subject to any tax withholding) in due proportion to the fractional share(s) to which they would otherwise have been entitled as a result of the
Reverse Stock Split. If, however, the amount which would otherwise be payable to an Ensco shareholder (other than a Former Rowan Shareholder, as defined below) in respect of their fractional share(s)
arising out of the consolidation is less than an aggregate amount equal to $5.00, then that amount shall not be paid to such holder but shall instead be retained by Ensco for its benefit. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As a UK company governed in part by the Companies Act 2006, Ensco cannot issue new shares (other than in certain limited circumstances) without
first obtaining approval from its shareholders. The Companies Act 2006 provides that this approval grants authority to the Ensco Board to allot shares in Ensco and to grant rights to subscribe for or
convert any security of Ensco into shares in the capital of Ensco. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At
the annual general meeting of Ensco held on May&nbsp;21, 2018, Ensco shareholders approved a resolution (based on the issued share capital of Ensco as at March&nbsp;26, 2018,
being the latest practicable date before the publication of the notice of Ensco's annual general meeting), to authorize the Ensco Board to allot shares and to grant rights to subscribe for or convert

Subject to approval of the transaction and the new Ensco ordinary shares being allotted as transaction consideration, Ensco is seeking to obtain a replacement authority for the Ensco Board to allot
shares to reflect the expected enlarged share capital of Ensco immediately following the Scheme of Arrangement becoming effective. </FONT></P>

<P style="font-family:times;"><FONT FACE="times" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Without
this grant of replacement authority from shareholders, the Ensco Board will only have the authority to issue shares up to the limits specified in the AGM Allotment Authority and
the AGM Pre-Emptive Allotment Authority. Approval of the Ensco General Allotment Authority Proposal will not, however, implicate any shareholder approval requirements of the NYSE for share issuances,
such as for executive compensation purposes, certain financing transactions or in connection with acquisitions, and Ensco would continue to be subject to the requirements to obtain shareholder
approval in those instances. </FONT></P>

<P style="font-family:times;"><FONT FACE="times" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Allotments
or issuances of ordinary shares for cash are subject to rights of pre-emption of the existing Ensco shareholders. If the Ensco shareholders approve the Ensco General
Disapplication of Pre-Emptive Rights Proposal and the Ensco Specified Disapplication of Pre-Emptive Rights Proposal described elsewhere in this joint proxy statement at the meeting, those pre-emption
rights will be disapplied to a limited extent as set forth in the Ensco General Disapplication of Pre-Emptive Rights
Proposal and the Ensco Specified Disapplication of Pre-Emptive Rights Proposal for new issues of shares subject to the Ensco General Allotment Authority Proposal. </FONT></P>

<P style="font-family:times;"><FONT FACE="times" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In accordance with Section&nbsp;14(A)(b) of the Exchange Act, Ensco is providing its shareholders with the opportunity to cast a non-binding,
advisory vote at the Ensco general meeting to approve the compensation that may be paid or become payable to Ensco's named executive officers in connection with the transaction and the agreements and
understandings pursuant to which such
compensation may be paid or has become payable in connection with the transaction, as disclosed under "The Transaction&#151;Ensco's Directors and Officers Have Financial Interests in the
Transaction&#151;Quantification of Potential Payments and Benefits to Ensco's Named Executive Officers in Connection with the Transaction." This non-binding advisory proposal relates only to
the contractual obligations of Ensco that exist as of the completion of the transaction (including arrangements that will become effective only if the transaction is consummated) that may result in a
payment to Ensco's named executive officers in connection with the consummation of the transaction (regardless of the timing of payment) and does not relate to any new compensation or other
arrangements following the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
required by those rules, Ensco is asking its shareholders to vote on the approval, on a non-binding, advisory basis, of the specified compensatory arrangements between Ensco and its
named executive officers related to the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Accordingly,
Ensco is requesting its shareholders adopt the following resolution, which is an ordinary resolution: </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"</FONT><FONT
SIZE=2><B><I>THAT, </I></B></FONT><FONT SIZE=2><I>the compensation that may be paid or become payable to Ensco's named executive officers in connection with the transaction, as well
as the specified compensatory arrangements between Ensco and its named executive officers, as disclosed pursuant to Item&nbsp;402(t) of Regulation&nbsp;S-K in the table in the section of the proxy
statement entitled "Quantification of Potential Payments to Named Executive Officers in Connection with the Transaction," including the associated narrative discussion, are hereby APPROVED on an
advisory (non-binding) basis."</I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
vote on executive compensation payable in connection with the transaction is a vote separate and apart from the vote to approve the Ensco Transaction Consideration Proposal.
Accordingly, Ensco shareholders may vote to approve the compensation that may be paid or become payable to Ensco's named executive officers in connection with the transaction and vote to not approve
the Ensco Transaction Consideration Proposal and vice versa. Assuming a quorum is present, the Ensco Transaction-Related Compensation Proposal will be passed if a simple majority of the votes cast at
the meeting (in person or by proxy) are cast in favor of such proposal, but because the vote is advisory in nature only, it will not be binding on Ensco. Accordingly, if the transaction is
consummated, Ensco will be contractually obligated to pay the compensation payable under such arrangements, subject only to the conditions applicable thereto, regardless of the outcome of the advisory
vote. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Completion
of transaction is not conditioned on the approval of the Ensco Transaction-Related Compensation Proposal. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</FONT><FONT
SIZE=2><B>The Ensco Board unanimously recommends that you vote "FOR" the Ensco Transaction-Related Compensation Proposal. If no indication is given as to how you want your
Ensco ordinary shares to be voted, the persons designated as proxies will vote the proxies received "FOR" the Ensco Transaction-Related Compensation Proposal.</B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As a UK company governed in part by the Companies Act 2006, before Ensco can raise additional capital through the issuance of ordinary shares of
Ensco for cash, Ensco is required first to offer those shares to its current shareholders in proportion to their shareholdings. The Companies Act 2006 permits shareholders to waive, or disapply, those
pre-emption rights. In addition, under UK law such pre-emption rights do not apply to any issuance of shares for non-cash consideration (including where shares are issued in exchange for other
securities). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At
the annual general meeting of Ensco held on May&nbsp;21, 2018, Ensco shareholders approved resolutions (based on the issued share capital of Ensco as at March&nbsp;26, 2018, being

<P style="font-family:times;"><FONT FACE="times" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If

Proposal and the Ensco Specified Disapplication of Pre-Emptive Rights Proposal would be effective until the conclusion of the next annual general meeting of Ensco shareholders following completion of
the transaction (or, if earlier, at the close of business on [&nbsp;&nbsp;&nbsp;&nbsp;</FONT><FONT FACE="SYMBOL" SIZE=2>&middot;</FONT><FONT FACE="times" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;], 2020). </FONT></P>

Ensco General Disapplication of Pre-Emptive Rights Proposal and the Ensco Specified Disapplication of Pre-Emptive Rights Proposal would give the Ensco Board the ability to raise

<P style="font-family:times;"><FONT FACE="times" SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The

allotment, or which has taken place in the preceding six-month period and is disclosed in the announcement of the corresponding allotment. A specified capital investment means one or more specific
capital investment related uses for the proceeds of an issuance of equity securities, in respect of which sufficient information regarding the effect of the transaction on Ensco, the assets which are

Scheme of Arrangement  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The transaction is to be implemented by means of a Court-sanctioned scheme of arrangement between Rowan and the Scheme Shareholders, under
Part&nbsp;26 of the Companies Act 2006 (the "Scheme of Arrangement"). Implementation of the Scheme of Arrangement requires approval of the Scheme of Arrangement by the Rowan shareholders at the
Rowan Court meeting and the approval of the Rowan Scheme and Articles Amendment Proposal as a special resolution by Rowan shareholders at the Rowan general meeting (the "Rowan shareholder meetings").
The Scheme of Arrangement also requires the sanction of the Court. The Scheme of Arrangement is set out in full in the section of this joint proxy statement titled "The Scheme of Arrangement." </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
purpose of the Scheme of Arrangement is to provide for Ensco to become the holder of the entire issued and to be issued ordinary share capital of Rowan. This is to be achieved by
transferring the Scheme Shares held by the Scheme Shareholders as at the Scheme Record Time to Ensco or its nominee, in consideration for which Ensco will issue new Ensco ordinary shares on the basis
set out in "The Scheme of Arrangement." </FONT></P>

Rowan Shareholder Meetings  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Before the Court's sanction can be sought for the Scheme of Arrangement, the Scheme of Arrangement requires approval by the passing of the Rowan
Scheme Proposal by Rowan shareholders at the Rowan Court meeting. The resolution must be approved by a majority in number of the Rowan shareholders as at the Voting Record Time present and voting (and
entitled to vote), either in person or by proxy, representing 75% or more in value of the Rowan ordinary shares held by such Rowan shareholders. Approval of the Rowan Scheme Proposal is required for
consummation of the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Rowan
shareholders are also being asked to consider and approve the Rowan Scheme and Articles Amendment Proposal and the Rowan Transaction-Related Compensation Proposal at the Rowan
general meeting. The Rowan Scheme and Articles Amendment Proposal will be proposed as a special resolution, which means, assuming a quorum is present, such proposal will be approved if at least 75% of
the votes cast are cast in favor thereof. The Rowan Scheme and Articles Amendment Proposal will
authorize the Rowan Board to implement the Scheme of Arrangement and to deal with certain ancillary matters including necessary amendments to Rowan's articles of association. Approval of the Rowan
Scheme and Articles Amendment Proposal is required for consummation of the transaction. The Rowan Transaction-Related Compensation Proposal will be proposed as an ordinary resolution, which means,
assuming a quorum is present, such proposal will be approved if a simple majority of the votes cast are in favor thereof. Approval of the Rowan Transaction-Related Compensation Proposal is not
required for the consummation of the transaction. </FONT></P>

the Scheme Record Time will be automatically acquired by Ensco on the same terms of the transaction (other than terms as to timings and formalities). Consequently, participants in the Rowan Stock
Plans (as defined in the transaction agreement) who receive Rowan ordinary shares on the exercise of share options after the Scheme Record Time will able to receive the same consideration as Scheme
Shareholders. These provisions will avoid any person (other than Ensco or its nominees) being left with Rowan ordinary shares after the Scheme of Arrangement becomes effective. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In accordance with Section&nbsp;14A of the Exchange Act, Rowan is providing its shareholders with the opportunity to cast an advisory,
non-binding vote at the Rowan general meeting on the compensation that may be paid or become payable to its named executive officers in connection with the transaction and the agreements and
understandings pursuant to which such compensation may be paid or become payable. For a more detailed summary of the compensation payments, see "The Transaction&#151;Rowan's Directors and
Officers Have Financial Interests in the Transaction" and "The Transaction&#151;Quantification of Potential Payments and Benefits to Rowan's Named Executive Officers in Connection with the
Transaction." As required by those rules, Rowan is asking its shareholders to vote on the adoption of the following resolution: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"RESOLVED,

Regulation&nbsp;S-K in the table in the section of the proxy statement entitled "The Transaction&#151;Rowan Directors and Officers Have Financial Interests in the Transaction." and "The
Transaction&#151;Quantification of Potential Payments and Benefits to Rowan's Named Executive Officers in Connection with the Transaction," including the associated narrative discussion, are

votes on each proposal are separate and apart from the votes on the other proposals. Accordingly, you may vote to approve certain of the proposals and vote not to approve other
proposals. Because the vote on this compensation proposal is advisory in nature only, it will not be binding on Rowan or
Ensco. Accordingly, if the proposals related to the Scheme of Arrangement are approved and the transaction is completed, the compensation may become payable, subject only to the conditions applicable
thereto, regardless of the outcome of the non-binding, advisory vote of the Rowan shareholders. </FONT></P>

Background of the Transaction  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Ensco Board, together with Ensco's executive management team, periodically reviews strategies to improve Ensco's capital structure, optimize
operational efficiency and enhance Ensco's future growth opportunities and shareholder value. The review of future growth opportunities encompasses a range of potential strategies, including:
improving Ensco's existing drilling rig fleet through capital improvements and investments in innovation; expanding the markets in which Ensco operates through joint ventures and/or strategic
partnerships; acquisitions of individual or groups of drilling rigs; and larger scale business combinations and strategic transactions, including combinations with peer group companies. The Ensco
Board established the Strategic Transactions Advisory Committee of the Ensco Board (the "Ensco Advisory Committee") in May 2017 consisting of Messrs.&nbsp;Paul E. Rowsey, the Non-Executive Chairman
of the Ensco Board, J. Roderick Clark, and C.&nbsp;Christopher Gaut to serve as an advisory committee assisting executive management with the review and assessment of potential strategic
transactions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
part of its strategy, Ensco acquired Atwood in October 2017. Following the acquisition of Atwood, Ensco continued its periodic review and also considered further strategic
combinations, including a combination with Rowan. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Similarly,
as part of Rowan's ongoing strategic planning process, the Rowan Board, together with Rowan's executive management team, regularly reviews and assesses Rowan's long-term
strategic plan and goals, opportunities, overall industry trends, the competitive environment in which Rowan operates and Rowan's short- and long-term performance, with the goal of promoting the
success of Rowan. In connection with these activities, the Rowan Board met from time-to-time in the ordinary course of business to consider and evaluate potential strategic alternatives, including
business combinations, acquisitions, dispositions, internal restructurings, joint ventures and similar transactions. Additionally, the Rowan Board from time-to-time assessed the potential risks Rowan
faced in executing its strategic plan, including the highly competitive landscape, cyclicality and intense price competition in the offshore drilling industry, the oversupply of drilling units in the
worldwide fleet, increased consolidation and restructuring of the offshore drilling industry, oil and gas prices and other macroeconomic trends. Specifically, due to these factors affecting the
industry generally, the Rowan Board concluded that a multi-pronged strategy was necessary to maximize shareholder value, including, among other things, exploring a variety of strategic transactions
and asset lease and purchase opportunities. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
part of Rowan's continuing assessment of strategic alternatives and efforts, Rowan executive management periodically met with investment banks covering the offshore drilling industry,
including Goldman Sachs. In addition, from time-to-time, Rowan received general inquiries or expressed interest regarding strategic transactions involving Rowan or certain of its businesses or assets
as well as discussing with potential counterparties the possible acquisition of additional rigs. The Rowan Board determined that none of these inquiries or resulting discussions was sufficiently
compelling to be potentially actionable, other than its formation of an offshore drilling joint venture with the Saudi Arabian Oil Company ("Aramco"), the purchase of two recently built jack-ups in
Brazil, both of which are described below and, ultimately, the combination with Ensco. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
the fourth quarter of 2014, certain representatives of Aramco entered into discussions with Dr.&nbsp;Thomas Burke, a director and Chief Executive Officer and President of Rowan, and
other Rowan representatives about the possibility of creating a joint venture with the purpose of offshore drilling in the Kingdom of Saudi Arabia and potentially elsewhere. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At
the beginning of 2015, Aramco commenced a formal process to select a partner for an offshore drilling company. In the second phase of this process, which started in the beginning of
the second </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>quarter
of 2015, Rowan was one of three finalists. The other two finalists were offshore drillers of significantly larger scale and more resources compared to Rowan. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
the third quarter of 2015, after two rounds of management presentations, which included financial and other proposals, Aramco selected Rowan as the potential future joint venture
partner for offshore drilling. Dr.&nbsp;Burke made multiple visits to Saudi Arabia to promote Rowan's proposal. The Rowan Board concluded that the Rowan executive management team, led by
Dr.&nbsp;Burke, was instrumental in helping Rowan achieve this result based on their personal effort to engage with Aramco and its strategic goals. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;From
the second quarter of 2015 to the fourth quarter of 2016, Rowan, represented by Dr.&nbsp;Burke and others, and Aramco negotiated the terms of the offshore drilling joint venture. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Between
late 2015 and August 2016, Dr.&nbsp;Carl Trowell, a director and President and Chief Executive Officer of Ensco, and Dr.&nbsp;Burke held several informal and non-specific
conversations exploring whether a combination of the two companies could add value to shareholders and under which conditions&nbsp;a combination might happen. These conversations did not result in
any formal engagement between the parties. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
the first quarter of 2016, Rowan made two proposals to purchase Party A, a global provider of offshore contract drilling services with jack-up rigs and lift-boats. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Additionally,
in the second and fourth quarters of 2016, Rowan made offers to purchase two harsh environment jack-ups from Party A. Ultimately, Party A decided to pursue other
opportunities for the sale of these assets. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
the summer and fall of 2016, members of the Rowan Board and Rowan executive management engaged in a series of exploratory conversations and meetings with Party B, a global
provider of offshore contract drilling services with jack-up and floating rigs, regarding a possible transaction. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Shortly
after Rowan had commenced further discussions with Party B, in August 2016, Dr.&nbsp;Trowell contacted Dr.&nbsp;Burke to discuss Rowan's interest in a possible business
combination with Ensco. Dr.&nbsp;Burke and Dr.&nbsp;Trowell agreed to further discuss a possible combination. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
October&nbsp;27, 2016, Rowan held a meeting of the Rowan Board, during which the Rowan Board and executive management conducted a strategic assessment, including assessing the
current industry dynamics, Rowan's competitive position and evaluating Rowan's long-range forecast under a variety of scenarios. At this meeting, the Rowan Board and Rowan executive management
discussed the conversation between Dr.&nbsp;Trowell and Dr.&nbsp;Burke. The Rowan Board directed executive management to temporarily postpone discussions with Ensco given on-going negotiations
regarding ARO, the on-going discussions with Party B and the continuing bid to acquire two harsh environment assets from Party A. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
November&nbsp;7, 2016, Dr.&nbsp;Trowell again contacted Dr.&nbsp;Burke to ask if Rowan would have an interest in pursuing a possible business combination. Dr.&nbsp;Burke
stated that he would discuss the matter with the Rowan Board. The Rowan Board later determined that Rowan would continue to explore a combination with Party B based on the perceived benefits of that
combination at that time. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
November&nbsp;21, 2016, Rowan and Aramco, through their subsidiaries, entered into a Shareholders' Agreement to create a 50/50 joint venture to own, manage and operate offshore
drilling units in Saudi Arabia and potentially elsewhere, which joint venture would ultimately be named Saudi Aramco Rowan Offshore Drilling Company ("ARO"). Dr.&nbsp;Burke committed to support the
new venture by taking a seat on the ARO board of directors. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
January 2017, Rowan engaged a financial advisor to review an opportunity to acquire Party C, a global provider of offshore contract drilling services with deep-water rigs. In that

<P style="font-family:times;"><FONT SIZE=2>Rowan
Board meeting was held during which the Rowan Board and executive management reviewed the opportunity with Party C and received the Rowan Board's support to further explore the opportunity. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
the first and second quarters of 2017, following Rowan's and Party B's entry into a confidentiality agreement, Rowan and Party B commenced a series of discussions to determine, among
other matters, if a mutually acceptable structure could be achieved. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
February&nbsp;24, 2017, Dr.&nbsp;Burke met in Europe with principals of Party D, a global provider of offshore contract drilling services with harsh environment semisubmersibles.
Rowan evaluated an acquisition of Party D, but executive management was ultimately unable to make a recommendation to the Rowan Board to pursue the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;From
January 2017 to March 2017, Party E, a global provider of offshore contract drilling services, and Mr.&nbsp;Stephen Butz, the Executive Vice President and Chief Financial Officer
of Rowan, had several conversations regarding the potential acquisition of Party E's jack-up fleet. Rowan's executive management evaluated the opportunity and, on March&nbsp;9, 2017, received
approval from the Rowan Board to make a non-binding offer. However, after Mr.&nbsp;Butz discussed price expectations with Party E, Rowan's executive management decided not to submit a formal bid on
the assets given the parties' disparate price expectations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
April&nbsp;26, 2017, the Rowan Board held a board meeting and Rowan executive management presented the opportunity to acquire Party C. The Rowan Board and executive management did
not find Party C's proposed valuation compelling, particularly given the associated risks of the opportunity and decided to keep monitoring the situation with Party C for changes rather than actively
pursue a potential business combination. The Rowan Board also reviewed several other potential transactions, including the acquisition of two recently built jack-ups in Brazil (P-59&nbsp;&amp; P-60) and
other potential corporate combinations. The Rowan Board also reviewed a combination with Party F, a global provider of offshore contract drilling services with jack-ups and floating rigs. While the
Rowan Board believed the industrial logic of a combination with Party F was attractive, they decided to not actively pursue the opportunity due to the low level of Party F's contracted backlog and
Party F's near-term debt maturities. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
a customer workshop on May&nbsp;3, 2017, Dr.&nbsp;Trowell approached Dr.&nbsp;Burke about Ensco's continued interest in a transaction with Rowan. Dr.&nbsp;Burke responded
that he would discuss a potential combination of Rowan and Ensco with the Rowan Board, which was scheduled to occur in late May 2017. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;10, 2017, Rowan was notified that it was the highest bidder at auction of P-59&nbsp;&amp; P-60, two recently built jack-ups in Brazil. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;25, 2017, Dr.&nbsp;Burke and Dr.&nbsp;Trowell met in London, England. Dr.&nbsp;Trowell noted that Ensco would be interested in a potential combination with Rowan.
Dr.&nbsp;Burke informed Dr.&nbsp;Trowell that Dr.&nbsp;Burke believed the Rowan Board would be amenable to further discussions provided the terms of the combination were compelling. However,
while Dr.&nbsp;Burke had discussed a potential combination with Ensco with Rowan's Chairman, he had yet to discuss it with the Rowan Board, which he was scheduled to do later that day. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Later
that day, Rowan's Board, together with executive management, held a telephonic meeting and discussed the potential purchase at auction of the two recently built jack-ups
(P-59&nbsp;&amp; P-60), a potential combination with Party B and a potential combination with Ensco. Rowan executive management recommended, that for several reasons, Rowan should focus on pursing a
transaction with Party B. If a transaction with Party B was unsuccessful, then Rowan's executive management recommended that Rowan could consider a combination with Ensco or Party G, a global provider

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;30, 2017, Ensco announced its acquisition of Atwood. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;1, 2017, the Chief Executive Officer of Party G and Dr.&nbsp;Burke discussed a possible transaction. Rowan and Party G entered into a confidentiality agreement on
June&nbsp;12, 2017, to permit the parties to exchange confidential materials. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;8, 2017, Party&nbsp;B informed Rowan that it would start a formal bidding process and provided Rowan with an instruction letter with respect to the process. Rowan
submitted a bid for Party&nbsp;B in July 2017. From that time through November 2017, Rowan and Party B engaged in extensive discussions regarding the financial and legal terms of a proposed
transaction and accompanying governance arrangements. Over that period, the Rowan Board met multiple times to review the potential combination with Party&nbsp;B. At its meeting in July, the Rowan
Board concurred with Rowan executive management's assessment that pursuing a combination with Party&nbsp;B was preferable to a transaction with Party G (with Ensco now engaged with the Atwood
combination). However, at the end of November
2017, negotiations with Party B were terminated after reaching an impasse over numerous remaining issues. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
October&nbsp;19, 2017, Rowan announced the commercial start-up of ARO. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
December&nbsp;10, 2017, the chief executive officer of Party G contacted representatives of Rowan to express Party G's interest in a possible transaction with Rowan.
Dr.&nbsp;Burke and Party G's Chief Executive Officer agreed to meet after the start of 2018. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
next day, on December&nbsp;11, 2017, Rowan and Party B agreed to recommence their negotiations that had terminated at the end of November 2017. From then until mid-February 2018,
Rowan and Party B continued discussions regarding a possible transaction. During this period, the Rowan Board evaluated the merits of the potential transaction with Party B several times. However,
towards the end of February 2018, Rowan and Party B again agreed to terminate discussions given continued disagreements over significant issues. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
January&nbsp;19, 2018, Rowan executive management met with advisors for Party H, a global provider of offshore contract drilling services with floating rigs that recently emerged
from restructuring, to discuss strategic alternatives under review by Party H. Rowan executive management commenced due diligence to evaluate the industrial and financial merits of a combination with
Party H. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
February&nbsp;5, 2018, a representative of Rowan discussed Party&nbsp;H's price expectations with Party&nbsp;H, after which Rowan executive management determined that further
diligence was not warranted given the significant difference in price expectations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;That
same month, Dr.&nbsp;Burke and the Chief Executive Officer of Party G met for breakfast to discuss a possible transaction between Rowan and Party G. Dr.&nbsp;Burke and Party G's
Chief Executive Officer agreed that each company's respective senior executives should meet to further discuss a possible transaction. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
February&nbsp;26, 2018, Rowan held a meeting of the Rowan Board to review various strategic alternatives, including remaining a standalone company, acquiring additional rigs in
asset transactions or engaging in a business combination with other offshore drilling companies. Representatives of Rowan executive management and Goldman Sachs also attended. The Rowan Board reviewed
material about and discussed potential transactions with both Ensco and Party G. There was a discussion concerning the likelihood that Ensco would pay a meaningful premium for Rowan given Ensco's
experience with the shareholder activist campaign with respect to the Atwood acquisition and overall market sentiment in the offshore drilling industry. The Rowan Board further discussed certain
concerns with Party G and potential solutions, none of which seemed commercially satisfactory, but which were </FONT></P>

worthy of additional investigation. The Rowan Board reviewed the 10-year historical exchange ratio of Rowan common shares compared to both Party G and Ensco's respective equity securities
and determined that the then-current exchange ratio was at a multi-year high-point in favor of Rowan shareholders. Rowan executive management advised the Rowan Board that, in management's opinion,
Ensco's fleet was significantly improved given its acquisition of Atwood, which made a combination with Ensco more attractive than before its merger with Atwood. The Rowan Board determined to pursue
both the Ensco and Party G opportunities contemporaneously and to evaluate each transaction at a further date after additional analysis. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
March&nbsp;3, 2018, executives of Rowan and their counterparts from Party G met to discuss initial due diligence around the aforementioned concerns. On March&nbsp;19, 2018, Rowan
and Party G entered into an amendment to the June&nbsp;12, 2017 confidentiality agreement to allow for the exchange of certain sensitive information through a clean team. Throughout the month, Rowan
and Party G exchanged due diligence materials. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
March&nbsp;23, 2018, Dr.&nbsp;Burke and Dr.&nbsp;Trowell met in Houston, Texas for dinner. Dr.&nbsp;Trowell again queried whether Rowan would be interested in a possible
transaction with Ensco. Dr.&nbsp;Trowell proposed a merger transaction structure, with neither party's shareholders receiving a premium to market value. Dr.&nbsp;Burke again reiterated that the
Rowan Board was amenable to discussions subject to acceptable terms. However, Dr.&nbsp;Burke noted that the Rowan Board would want a premium for Rowan shareholders. Dr.&nbsp;Trowell reiterated the
merger transaction structure, with neither party's shareholders receiving a premium to market value. Dr.&nbsp;Burke committed to communicate a combination as described by Dr.&nbsp;Trowell to the
chairman of the Rowan Board, Mr.&nbsp;William Albrecht, and the broader Rowan Board. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
March&nbsp;28, 2018, Rowan held a meeting of the Rowan Board during which the Rowan Board and Rowan executive management discussed both potential transactions with Party G and
Ensco, in addition to other routine matters. The Rowan Board determined that concerns around Party G undercut the strategic rationale of the possible transaction with Party G and the potential benefit
to Rowan shareholders. The Rowan Board instructed Rowan executive management to terminate discussions with Party G. The Rowan Board then discussed a possible combination with Ensco. Following that
discussion, the Rowan Board instructed Rowan executive management to continue discussions with Ensco. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
March&nbsp;29, 2018, Rowan terminated discussions with Party G regarding a potential transaction. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
April&nbsp;26, 2018, Ensco and Rowan entered into a mutual confidentiality agreement (the "confidentiality agreement") with mutual standstill provisions. Following the execution of
the confidentiality agreement, Ensco and Rowan began to share confidential information regarding their operations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
a meeting of the Ensco Advisory Committee held on April&nbsp;27, 2018, Ensco executive management, consisting of Dr.&nbsp;Trowell, Patrick Carey Lowe, Executive Vice President
and Chief Operating Officer of Ensco, Jonathan Baksht, Senior Vice President and Chief Financial Officer of Ensco, and Michael T. McGuinty, Senior Vice President, General Counsel and Secretary of
Ensco, presented a potential transaction with Rowan to the Ensco Advisory Committee. Following an update call with the Ensco Board later that day, the Ensco Board authorized Ensco executive management
to send a non-binding proposal to Rowan consistent with the terms presented to the Board. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Throughout

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;7, 2018, Rowan held a meeting of the Rowan Board during which the Rowan Board and executive management of Rowan and certain of Rowan's financial and legal advisors
discussed the proposal sent by Ensco and the possible combination between the companies. The Rowan Board asked
questions and considered the non-binding proposal in detail, together with the executive management of Rowan. The Rowan Board discussed the risks of certain unresolved Ensco contingent liabilities,
namely the litigation and regulatory review in connection with a terminated drilling contract in Brazil and certain on-going governmental investigations with respect to the procurement of such
drilling contract (collectively, the "Brazil matter"), and attractiveness of a combination with Ensco versus remaining a standalone company. The Rowan Board also discussed the implications of asking
for and the requirement to obtain a waiver of certain rights that Aramco had with respect to ARO in the event of a change in control of Rowan (the "CIC Rights"). The Rowan Board instructed executive
management to continue discussions with Ensco. </FONT></P>

Dr.&nbsp;Burke, Mr.&nbsp;Butz, Mark F. Mai, Executive Vice President, General Counsel and Secretary of Rowan, and Son Vann, Vice President of Corporate Development of Rowan, to discuss ARO. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;18, 2018, Dr.&nbsp;Trowell and Messrs.&nbsp;McGuinty, Baksht and Lowe held a telephonic meeting with Dr.&nbsp;Burke and Messrs.&nbsp;Butz, Mai and Vann to discuss
Ensco's business operations, including an overview of its rig fleet. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
a regular quarterly Ensco Board meeting held on May&nbsp;20 and 21, 2018, Dr.&nbsp;Trowell and Messrs.&nbsp;Lowe, Baksht and McGuinty presented the Rowan opportunity to the
Ensco Board as one of several potential strategic options and discussed with the Ensco Board Rowan's fleet quality, potential synergies, geographic footprint, and the unique growth opportunity
presented by Rowan's partnership with Aramco through ARO. Given the attractiveness of a combination with Rowan, the Ensco Board determined that Ensco should continue discussions with Rowan regarding a
potential transaction. </FONT></P>

May&nbsp;24, 2018, Rowan held a meeting of the Rowan Board during which the Rowan Board and executive management discussed various strategic alternatives available to Rowan,
including three potential transactions, the possible combination with Ensco and several other opportunities to acquire assets from counterparties in financial distress. The Rowan Board discussed in
depth the possible combination between Rowan and Ensco and a response to Ensco's proposal from April&nbsp;27, 2018. Among other things, the Rowan Board instructed executive management to pursue
terms of a possible combination that would result in Rowan's shareholders collectively owning 45% of the combined company pro forma for the transaction and provide for certain governance arrangements
in favor of Rowan. The Rowan Board also instructed Rowan executive management to further evaluate potential exposure arising from the Brazil matter. The Rowan Board discussed the CIC Rights and the
reasons why Aramco might exercise these rights. Additionally, the Rowan Board discussed whether Rowan must have the right to appoint the initial Chief Executive Officer of the combined company because
of the important dynamics involved in Dr.&nbsp;Burke's continued contributions to ARO and the ongoing relationship with Aramco. The Rowan Board concluded that continuity of Dr.&nbsp;Burke's
leadership between Rowan and the combined company was integral to delivering value from ARO. The Rowan Board instructed Rowan executive management to communicate these terms to Ensco. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;29, 2018, Rowan sent Ensco a letter in response to Ensco's April&nbsp;27<SUP>th</SUP>&nbsp;proposal. In this non-binding proposal, Rowan expressed its interest in
continuing discussions regarding a potential transaction and, based on instructions from the Rowan Board, proposed an exchange ratio that would result in Rowan's shareholders collectively owning 45%
of the combined company pro forma for the transaction. In addition, Rowan's letter described certain governance matters, including a desire that Rowan's Chief Executive Officer be the Chief Executive
Officer of the combined company, that Ensco's Chief Executive Officer or its chairman of the board be the chairman of the board of directors of the combined company, that Ensco and Rowan designate an
equal number of directors to the combined company's board and that the committees of the combined company's board have equal representation of legacy Ensco and Rowan directors. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Also
on May&nbsp;29, 2018, Ensco retained Morgan Stanley to act as a financial advisor to Ensco in connection with a potential transaction with Rowan. Morgan Stanley's engagement was
formalized by execution of an engagement letter with Ensco on October&nbsp;2, 2018. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;3, 2018, the Ensco Board participated in a telephone call with representatives of Morgan Stanley to discuss a response to Rowan's May&nbsp;29th&nbsp;letter and the
terms of a potential transaction proposed by Rowan. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;5, 2018, Ensco sent an updated non-binding proposal to Rowan, which proposed that Rowan shareholders receive 2.50 ordinary shares of Ensco for each Rowan ordinary share as
transaction consideration. In addition, the proposal covered certain governance matters, including that Ensco's Chief Executive Officer be the Chief Executive Officer of the combined company, that the
chairman of the board of the combined company would be nominated by Rowan, that the combined company board would consist of 11 directors, including six Ensco directors and five Rowan directors and
that the headquarters of the combined company would be located in London, England or Houston, Texas. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Later
that day, Dr.&nbsp;Burke and Dr.&nbsp;Trowell discussed Ensco's proposal. Dr.&nbsp;Trowell told Dr.&nbsp;Burke that, due to feedback from Ensco shareholders during the
proxy solicitation with respect to the Atwood acquisition, Ensco would not agree to pay the premium that Rowan had sought in its May&nbsp;29th&nbsp;response. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;11, 2018, the Rowan Board met to discuss, among other items, Rowan's pursuit of a purchase of assets from Party I, and a response to Ensco's June&nbsp;5th&nbsp;letter.
As of June&nbsp;8, 2018, the last trading day before the Rowan Board meeting, the exchange ratio was approximately 2.46 based on the close of trading the previous day, having moved in Rowan's favor
the last five days, making the Ensco proposal effectively an at-market offer. The Rowan Board again reviewed the implications of the CIC Rights, the dynamics involved in Dr.&nbsp;Burke's continued
contributions to ARO and determined that to ensure success of ARO, the combined company's CEO would need to be Dr.&nbsp;Burke. The Rowan Board again expressed significant concern over the contingent
liability associated with the Brazil matter and instructed executive management to continue to evaluate that exposure. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Dr.&nbsp;Burke
and Dr.&nbsp;Trowell had a lunch meeting in Houston, Texas on June&nbsp;14, 2018 to discuss the terms of Ensco's June&nbsp;5, 2018 proposal, the need for a consent
from Aramco related to the CIC Rights and outstanding due diligence items. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;16, 2018, Dr.&nbsp;Burke and a representative from Party B held a meeting to discuss the previously abandoned negotiations and agreed that recommencing negotiations was
not warranted. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;17, 2018, Dr.&nbsp;Burke met with a board member of Party J, a global provider of offshore contract drilling services with jack-ups rigs, in London, England. At the
meeting, they discussed the market
generally for offshore drilling services and a potential combination between Rowan and Party J. The representative of Party J stated that he would like for Rowan and Party J to engage in a
transaction. Dr.&nbsp;Burke responded that he would discuss the opportunity with the Rowan Board but deemed the combination likely unattractive to Rowan's shareholders because, in Dr.&nbsp;Burke's
opinion, Party J's relative valuation was much higher than Rowan's, its equity had significantly lower trading volumes than Rowan and Party J had a weak backlog position. The Rowan Board ultimately
agreed with Dr.&nbsp;Burke's assessment. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;18, 2018, Dr.&nbsp;Burke and Mr.&nbsp;Albrecht met with Dr.&nbsp;Trowell and Mr.&nbsp;Rowsey in London to discuss the terms of a potential transaction, including
the proposed exchange ratio and the strategic rationale of the transaction. At the meeting, Mr.&nbsp;Albrecht noted the Rowan Board was focused on the continuity in relationships with ARO,
particularly with respect with Dr.&nbsp;Burke's role in the combined company. Dr.&nbsp;Trowell and Mr.&nbsp;Rowsey insisted that the transaction be effected in an at-market, no premium
transaction based on the trailing 30-day average share price for Rowan ordinary shares. Messrs.&nbsp;Rowsey and Albrecht met separately later that day to discuss governance matters. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Between
June&nbsp;20, 2018 and August&nbsp;31, 2018, Dr.&nbsp;Trowell and Dr.&nbsp;Burke had multiple phone calls to discuss the terms of a potential transaction between Rowan
and Ensco and the transaction process generally. During this time period and through the execution of the transaction agreement, Dr.&nbsp;Trowell updated Mr.&nbsp;Rowsey and Dr.&nbsp;Burke
updated Mr.&nbsp;Albrecht, in each case, on a regular basis regarding the status of discussions between the parties, and Mr.&nbsp;Rowsey had multiple phone calls with individual Ensco directors to
discuss the same, and Mr.&nbsp;Albrecht had multiple phone calls with individual Rowan directors to discuss the same. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;29, 2018, Dr.&nbsp;Burke and Dr.&nbsp;Trowell had a telephone conversation. Dr.&nbsp;Trowell reiterated to Dr.&nbsp;Burke the terms on which the Ensco Board would
engage in a business combination transaction, including an at-market, no premium transaction based on the trailing 30-day average share price, that Ensco would appoint the initial chief executive
officer of the combined company and that Rowan would appoint the executive chairman of the combined company for a defined period of time. Dr.&nbsp;Burke expressed to Dr.&nbsp;Trowell the Rowan
Board's concern with the Brazil matter. Dr.&nbsp;Burke also informed Dr.&nbsp;Trowell that the Rowan Board was still considering Ensco's proposals and the various discussions during the preceding
month and would further discuss them at a board meeting in July 2018. Using an exchange ratio based on the close of trading the previous day, Ensco's "at market proposal" would mean that Rowan
shareholders receive 2.214 Ensco ordinary shares for each Rowan ordinary share as transaction consideration. </FONT></P>

had communicated to Dr.&nbsp;Burke. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
July&nbsp;3, 2018, Dr.&nbsp;Burke and Dr.&nbsp;Trowell had a call to discuss the transaction. Dr.&nbsp;Burke told Dr.&nbsp;Trowell that, based on conversations between
Dr.&nbsp;Burke and members of the Rowan Board, a merger on the terms proposed by Ensco seemed unlikely, but the Rowan Board would discuss the potential transaction at its board meeting in London at
the end of July. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
July&nbsp;9, 2018, Dr.&nbsp;Burke met representatives of Party I in London, England to continue their discussions of May&nbsp;22, 2018. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Twice
in July 2018, representatives of Rowan met or communicated with officials from shipyards to discuss an acquisition of drilling assets from a financially distressed counterparty. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
July&nbsp;12, 2018, Dr.&nbsp;Burke and Mr.&nbsp;Butz met with a significant shareholder in Houston, Texas. At the meeting, the shareholder presented a concept for significantly
restructuring Rowan's balance sheet while creating a jack-up company and drillship company, both publicly traded entities, both to be managed by the current Rowan management team. The Rowan Board
subsequently reviewed the concept and determined that the transaction would not be in the best interest of Rowan stakeholders given the importance of scale, cost structure and credit profile, which
the proposed concept would cause to deteriorate. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
July&nbsp;25, 26 and 27, 2018, Rowan held a meeting of the Rowan Board. The Rowan Board reviewed the medium- and long-term outlook for deep-water based on a third-party analysis and
compared that to Rowan's executive management's assessment of the future of the deep-water market. The Rowan Board also continued its on-going strategic assessment, including examining various
alternatives to a combination transaction such as a sale of Rowan drill ships or the movement of certain assets into a new publicly traded holding companies. The Rowan Board determined that these
alternatives were not attractive. The Rowan Board also considered the acquisition of certain jack-up and floating rig opportunities. The Rowan Board concluded that the uncertain financial returns
against the significant risks of these opportunities did not merit further due diligence at this time. Rowan executive management advised the Rowan Board that, in management's opinion, the opportunity
with Party I was considerably less attractive than a combination with Ensco. Nevertheless, Rowan's executive management proposed that it was worth exploring this opportunity in the event a combination
with Ensco could not be achieved. The Rowan Board instructed Rowan executive management to continue its engagement with Party I. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
July&nbsp;27, 2018, during the Rowan Board meeting Mr.&nbsp;Albrecht and Mr.&nbsp;Rowsey had a telephone conversation to discuss various aspects of a proposed transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
the same Rowan Board meeting, the Rowan Board reviewed the strategic rationale of the Rowan/Ensco combination, together with the strengths and weaknesses of the proposed
transaction. The Rowan Board also considered (1)&nbsp;the historic exchange ratio between the two companies (and that the exchange ratio had moved in Ensco's favor since negotiations commenced),
(2)&nbsp;the relative EBITDA
and other financial contributions from the two companies, (3)&nbsp;certain pro forma financials of the combined company, (4)&nbsp;expected benefits of the proposed transaction
vis-&agrave;-vis Rowan on a standalone basis, (5)&nbsp;the Brazil matter and various considerations around ARO and (6)&nbsp;precedent merger-of-equals transactions. After discussion, and
upon receiving advice from its legal and financial advisors, the Rowan Board advised Rowan executive management to continue its pursuit of the transaction and then discussed the elements of a proposed
response to Ensco. Using an exchange ratio based on the close of trading the previous day, Ensco's "at market proposal" would mean that Rowan shareholders receive 2.003 Ensco ordinary shares for each
Rowan ordinary share. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
August&nbsp;2, August&nbsp;12 and August&nbsp;24, 2018, representatives of Rowan and representatives of Party I had telephone calls to continue their conversation of

August&nbsp;8, 2018, in a phone conversation between Dr.&nbsp;Burke and Mr.&nbsp;Albrecht, Dr.&nbsp;Burke noted that, using an exchange ratio based on the close of trading the
previous day, Ensco's "at market proposal" would mean that Rowan shareholders would receive 1.788 Ensco ordinary shares for each Rowan ordinary share. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
August&nbsp;16, 2018, Ensco and its customer announced that they had settled all claims between them relating to the Brazil matter, with no payments being made by either party.
Rowan executive management considered this an important milestone that made a combination with Ensco more attractive. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
an Ensco Board meeting held on August&nbsp;21, 2018, Mr.&nbsp;Rowsey and Dr.&nbsp;Trowell updated the Ensco Board regarding their recent discussions with Mr.&nbsp;Albrecht
and Dr.&nbsp;Burke relating to the terms of a potential transaction and proposed governance matters, including Rowan's desire that Dr.&nbsp;Burke be the Chief Executive Officer of the combined
company due to his involvement in ARO and his working relationship with Aramco. The Ensco Board determined to continue discussions with Rowan on the basis that Rowan's Chief Executive Officer be the
Chief Executive Officer of the combined company provided that the transaction reflected an at-market, no premium combination, Ensco directors retained six of the 11 combined company board seats and
Ensco retained the right to appoint other key executive management positions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
August&nbsp;24, 2018, Ensco sent a letter to Rowan reiterating its interest in a potential combination of Ensco and Rowan. The letter outlined Ensco's proposed terms for the
potential transaction, including (1)&nbsp;an all-stock transaction, (2)&nbsp;a no premium combination resulting in a relative ownership split in the combined company of 62% for Ensco shareholders
and 38% for Rowan shareholders, (3)&nbsp;agreement that Rowan's Chief Executive Officer would serve as Chief Executive Officer of the combined company,
(4)&nbsp;appointment of the Chief Operating Officer, Chief Financial Officer and General Counsel of the combined company by Ensco, (5)&nbsp;appointment of Ensco's Chief Executive Officer as
Executive Chairman of the combined company, (6)&nbsp;an 11 member board of directors of the combined company, comprising six Ensco directors and five Rowan directors, (7)&nbsp;a condition to
closing that Rowan obtain any required consents by the parties to ARO required in connection with the proposed transaction, and (8)&nbsp;the headquarters of the combined company would be in London,
England. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
August&nbsp;28, 2018, on behalf of Ensco, Dr.&nbsp;Trowell and Mr.&nbsp;Rowsey delivered to Mr.&nbsp;Albrecht and Dr.&nbsp;Burke, on behalf of Rowan, an additional
non-binding letter clarifying certain governance arrangements, including how certain appointment and removal rights would work for the Executive Chairman of the combined company, the term of the
Executive Chairman's tenure, and the roles and responsibilities of the Executive Chairman vis-&agrave;-vis the chief executive officer of the combined company. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
August&nbsp;29, 2018, Dr.&nbsp;Trowell contacted Dr.&nbsp;Burke to let him know that the SEC had informed Ensco that it was concluding its investigation related to the Brazil
matter without any enforcement action. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
August&nbsp;31, 2018, the Rowan Board convened a meeting by telephone to review the status of the potential transaction and its strategic rationale. The Rowan Board, among other
items, reviewed the proposed exchange ratio versus historic share performance between the two companies. The Rowan Board also reviewed additional transaction considerations, including the magnitude
and likelihood of expected synergies and the strategic advantages the combined company would have due to increased scale (including the capacity to develop new technology, the benefits of a more
diverse fleet and the ability to absorb the fixed costs of operations). In light of those transaction considerations, the Rowan Board determined a combination with Ensco to be highly attractive and
expressed willingness to consider an at-market exchange ratio. However, the Rowan Board instructed Rowan executive management that Rowan would not accept any discount to the trading price of Rowan's
ordinary shares </FONT></P>

prior to announcement. Rowan management also advised the Rowan Board that the SEC's investigation regarding the Brazil matter had concluded, which made an Ensco combination more
attractive. Using an exchange ratio based on the close of trading the previous day, Ensco's "at market proposal" would mean that Rowan shareholders receive 2.014 Ensco ordinary shares for each Rowan
ordinary share. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Rowan
executive management also again reviewed the proposal previously put forward by the Rowan shareholder which, after discussion, the Rowan Board again declined to pursue as the
proposal being put forth by Ensco was considerably more compelling for the long-term success of Rowan. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
August&nbsp;31, 2018, Rowan sent a letter to Ensco in response to Ensco's August&nbsp;24, 2018 letter, as clarified by Ensco's letter from August&nbsp;28, 2018, indicating
Rowan's continued interest in the transaction and in proceeding to solicit Aramco's support for the proposed transaction. In its non-binding letter, Rowan proposed that (1)&nbsp;the combined company
include an independent lead director, which would be Rowan's chairman of the board initially, (2)&nbsp;Dr.&nbsp;Burke would waive the accelerated vesting of an equity retention grant awarded in
February 2017 and severance rights, both triggered by the move of his employment to London in connection with the proposed transaction, (3)&nbsp;the Executive Chairman of the combined company would
serve for a term of 18&nbsp;months following the closing of the proposed transaction, and (4)&nbsp;supermajority voting requirements for the combined company's board and any agreed governance
requirements of the combined company would be set forth in revised articles of association of the combined company. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
following day, Dr.&nbsp;Burke and Dr.&nbsp;Trowell had a telephone conversation regarding Rowan's response. During this call, Dr.&nbsp;Burke and Dr.&nbsp;Trowell concluded
that the governance arrangements were the most significant issues remaining. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
September&nbsp;4, 2018, Ensco publicly announced that the SEC had concluded its investigation and that the U.S. Department of Justice had stated that it had closed its inquiry into
the Brazil matter. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At
an industry conference on September&nbsp;4, 2018, members of Rowan executive management made an investor presentation that included further disclosures regarding ARO, for which
Rowan had recently received permission from Aramco. Later that day, Dr.&nbsp;Burke and Dr.&nbsp;Trowell met to discuss the potential combination and had a follow-up telephone conversation on
September&nbsp;6, 2018. Following the conversation, they had agreed a framework for determining the combined company's management team and generally resolved issues with respect to the roles and
responsibilities of the Executive Chairman and chief executive officer of the combined company. Additionally, they discussed the strategy for obtaining Aramco's waiver of the CIC Rights. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
September&nbsp;7, 2018, Mr.&nbsp;Rowsey called Mr.&nbsp;Albrecht to discuss the potential transaction, including the strategic rationale of the transaction, exchange ratio,

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
September&nbsp;10, 2018, Mr.&nbsp;Rowsey and Mr.&nbsp;Gaut met with Mr.&nbsp;Albrecht and Thomas R. Hix, a director of Rowan, in Houston, Texas to discuss the proposed

September&nbsp;20, 2018, Gibson Dunn delivered to Kirkland a revised draft of the transaction agreement. Between September&nbsp;20, 2018 and October&nbsp;7, 2018, Gibson Dunn
and Slaughter, on behalf of Ensco, and Kirkland, on behalf of Rowan, engaged in a number of conversations regarding, and exchanged drafts of, the documents for the potential transaction, including,

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Between
September&nbsp;23, 2018 and October&nbsp;4, 2018, Dr.&nbsp;Burke and Dr.&nbsp;Trowell had a series of telephone conversations regarding various aspects of the potential

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
September&nbsp;24, 2018, Rowan held a meeting of the Rowan Board. During the meeting, representatives of Rowan executive management and Goldman Sachs provided the Rowan Board with
an overview of financial due diligence conducted to date and representatives of Rowan management and Kirkland provided the Rowan Board with an overview of legal due diligence conducted to date. The
Rowan Board asked questions with respect to the due diligence findings and made additional requests for further due diligence with respect to certain matters. Representatives of Kirkland then provided
a summary of the then-current draft of the transaction agreement and the remaining material issues and answered the Rowan Board's questions with respect thereto. Following these presentations, the
Rowan Board discussed the benefits and detriments of the transaction. Among other things, the Rowan Board discussed the magnitude and likelihood of expected synergies and operational benefits the
combined company would achieve, and further discussed the importance the CIC Rights waiver to achieve such expectations. Finally, the Rowan Board discussed the open issues and instructed executive
management of Rowan, Kirkland and Goldman Sachs to attempt to resolve the remaining open issues. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Additionally,
at the same meeting, Dr.&nbsp;Burke agreed to Ensco's requirement that he waive his rights to acceleration of his time-based unvested restricted stock awards in order to
align his interests with the shareholders of the combined company and reduce the transaction costs. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
October&nbsp;4, 2018, Mukamala Oil Field Services Limited, a subsidiary of Saudi Aramco Development Company and holder of 50% of the interests of ARO, delivered a letter that, among
other things, waived its option, arising in connection with the proposed transaction, to purchase Rowan's interest in ARO and consented to the completion of the transaction. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;That
same day, Dr.&nbsp;Burke and Dr.&nbsp;Trowell met in London to discuss the material outstanding issues, including the governance arrangements for the combined company. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Between

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
October&nbsp;5, 2018, Dr.&nbsp;Burke and Dr.&nbsp;Trowell met in London again to discuss material outstanding issues, including the exchange ratio and the governance
arrangements for the combined company. After the close of trading on the NYSE, Dr.&nbsp;Burke and Dr.&nbsp;Trowell had a telephone call to discuss the exchange ratio to use in the transaction.
Dr.&nbsp;Burke proposed that the exchange ratio should be based on the closing price at the end of trading that day and, therefore, should be 2.215. Dr.&nbsp;Trowell stated that he would discuss
the matter with the Ensco Board. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
same day, Ensco retained Citigroup Global Markets&nbsp;Inc. and HSBC&nbsp;Securities (USA)&nbsp;Inc. as co-financial advisors to Ensco in connection with the potential
transaction with Rowan. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Later
on October&nbsp;6, 2018, the Ensco Board held a meeting, together with its legal and financial advisors, to discuss the proposed transaction. At this meeting, among other

dated October&nbsp;6, 2018, that, as of the date of such opinion, and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and

a discussion regarding the proposed transaction by the Ensco Board, including a discussion of the Chief Executive Officer and Executive Chairman Employment Agreements in executive session, the Ensco
Board unanimously determined that the form, terms and provisions of the transaction agreement and the transactions contemplated thereby, including the transaction and the allotment and issuance of the
Ensco ordinary shares and the Reverse Stock Split, were advisable, fair and reasonable to and in the best interests of Ensco and its shareholders. The Ensco Board unanimously determined to recommend
that Ensco shareholders vote to approve the Ensco Transaction Consideration Proposal and the Ensco Reverse Stock Split Proposal. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Following

reimbursement if a party's shareholders did not approve the transaction at $15&nbsp;million instead of $10&nbsp;million and establishing a threshold for remedial actions related to antitrust
matters at $400&nbsp;million. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Later
on October&nbsp;6, 2018, Rowan held a meeting of the Rowan Board in London, England. Members of Rowan's executive management, together with representatives from Kirkland, Goldman
Sachs and Rowan's compensation consultants, participated in the meeting in person and by telephone conference. At the meeting, representatives of Kirkland provided to the Rowan Board an update
regarding the terms of the transaction, including the terms of the transaction agreement, the governance policy and the employment agreements of Dr.&nbsp;Burke and Dr.&nbsp;Trowell to be entered
into in connection with the transaction. The Rowan Board discussed that the parties had agreed to an exchange ratio of 2.215 Ensco ordinary shares for each Rowan ordinary share. Also at the meeting,
Goldman Sachs reviewed with the Rowan Board its financial analyses of the exchange ratio provided for in the transaction and delivered to the Rowan Board an oral opinion, confirmed by delivery of a
written opinion dated October&nbsp;7, 2018, to the effect that, as of such date and based upon and subject to the factors and assumptions stated in such opinion, the exchange ratio pursuant to the
transaction agreement was fair, from a financial point of view, to the holders (other than Ensco and its affiliates) of the Rowan ordinary shares. The Rowan Board then (i)&nbsp;unanimously
determined that the transaction and the scheme of arrangement were in the best interests of Rowan and the Rowan shareholders, and declared it advisable to enter into the transaction agreement,
(ii)&nbsp;approved the execution, delivery and performance of the transaction agreement and the consummation of the transactions contemplated
thereby, including the transaction and the scheme of arrangement, and (iii)&nbsp;resolved to recommend the adoption of the transaction agreement and the passing of the Rowan shareholder resolutions
by the Rowan shareholders. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;That

discussion of the information and factors considered by the Ensco Board in reaching its conclusion and recommendations includes all of the material factors considered by the Ensco
Board but is not intended to be exhaustive and is not provided in any specific order or ranking. In view of the wide variety of factors considered by the Ensco Board in evaluating the transaction
agreement and the
actions required and contemplated thereby and the complexity of these matters, the Ensco Board did not find it practicable to, and did not attempt to, quantify, rank or otherwise assign relative
weight to those factors. In addition, different members of the Ensco Board may have given different weight to different factors. The Ensco Board did not reach any specific conclusion with respect to
any of the factors considered and instead conducted an overall analysis of such factors and determined that, in the aggregate, the potential benefits considered outweighed the potential risks or
possible negative consequences of approving the transaction agreement and the allotment and issuance of Ensco ordinary shares pursuant to the transaction agreement. </FONT></P>

Rowan's Reasons for the Transaction; Recommendation of the Rowan Board of Directors  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On October&nbsp;6, 2018, the Rowan Board unanimously determined that the transaction agreement and the Scheme of Arrangement are in the best
interests of Rowan and Rowan's shareholders, and declared it advisable to enter into the transaction agreement and Scheme of Arrangement, and approved the execution, delivery and performance of the
transaction agreement and the Scheme of Arrangement and the transactions contemplated thereby are fair to and in the best interests of Rowan's shareholders. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</FONT><FONT

the other proposals at the Rowan special meetings.</B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
its evaluation of the transaction agreement, Scheme of Arrangement and the transactions contemplated thereby, the Rowan Board consulted with Rowan's executive management and Rowan's
outside legal and financial advisors and considered several potentially positive factors, including the following (not necessarily in order of relative
importance):</FONT></P>

<DL compact>
<DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2>&#149;</FONT></DT><DD style="font-family:times;"><FONT SIZE=2> The belief that the transaction would create a leading global offshore drilling company with enhanced scale, large high-graded fleet, clear
growth strategies and a diversified revenue mix across segments, geographies and customers, resulting in improved opportunities for growth, cost savings, earnings and innovation relative to what Rowan
could achieve on a standalone basis. </FONT><FONT SIZE=2>
<BR><BR></FONT></DD><DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2>&#149;</FONT></DT><DD style="font-family:times;"><FONT SIZE=2> The fact that, in receiving Ensco ordinary shares in the transaction, the holders of Rowan ordinary shares will participate in a combined
entity that, among other things, will have increased share liquidity, will have a strong balance sheet, will be capable of pursuing significantly larger growth opportunities, and will participate in
the increased diversification of the assets and operations of the combined entity, in each case as compared to Rowan on a standalone basis. </FONT><FONT SIZE=2>
<BR><BR></FONT></DD><DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2>&#149;</FONT></DT><DD style="font-family:times;"><FONT SIZE=2> The fact that the Rowan Board and Rowan's executive management estimate that the combined company will generate annual run-rate cost synergies
of approximately $150&nbsp;million, of which 75% is expected to be realized within one year of the consummation of the transaction, which is expected to result in the combined company having greater
potential to achieve further earnings growth and generate accretive cash flow the year following the consummation of the transaction. </FONT><FONT SIZE=2>

maximize shareholder value, including strategic transactions and asset lease and purchase opportunities in its deep water and jack-up rig business lines and, despite the successful execution of two
such transactions, Rowan's deep-water fleet did not achieve the scale necessary to fully absorb fixed cost operations. </FONT><FONT SIZE=2>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Ensco Board retained Morgan Stanley to provide it with financial advisory services in connection with the proposed transaction and to
provide a financial opinion. The Ensco Board selected Morgan Stanley to act as its financial advisor based on Morgan Stanley's qualifications, expertise and reputation and its knowledge of the
business and affairs of Ensco. On October&nbsp;6, 2018, at a meeting of the Ensco Board, Morgan Stanley rendered its oral opinion, subsequently confirmed by delivery of a written opinion, dated
October&nbsp;6, 2018, that, as of that date and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of
review undertaken by Morgan Stanley as set forth in the written opinion, the exchange ratio pursuant to the transaction agreement was fair from a financial point of view to Ensco. </FONT></P>

Stanley assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made
available to it by Rowan and Ensco, and formed a substantial basis for its opinion. With respect to the financial
projections, including information relating to certain strategic, financial and operational benefits anticipated from the transaction, Morgan Stanley assumed that they had been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the respective managements of Rowan and Ensco of the future financial performance of Rowan and Ensco. For purposes of its
analysis, Morgan Stanley, at the direction of Ensco, relied on financial projections relating to Rowan and Ensco, in each case prepared by the management of Ensco. Morgan Stanley was advised by Ensco
and assumed, with Ensco's consent, that the projections prepared by the management of Ensco were a reasonable basis upon which to evaluate the business and financial prospects of Ensco and Rowan.
Morgan Stanley expressed no view as to such projections or the assumptions on which they were based. Morgan Stanley relied upon, without independent verification, the assessment by the management of
Ensco of: (i)&nbsp;the strategic, financial and other benefits expected to result from the transaction; (ii)&nbsp;the timing and risks associated with the integration of Rowan and Ensco; and
(iii)&nbsp;Ensco's ability to retain key employees of Rowan and Ensco, respectively. In addition, Morgan Stanley assumed that the transaction would be consummated in accordance with the terms set
forth in the transaction agreement without any waiver, amendment or delay of any terms or conditions, including, among other things, that the transaction would be treated as a tax-free reorganization,
pursuant to the Internal Revenue Code and that the definitive transaction agreement would not differ in any material respect from the draft thereof furnished to it. Morgan Stanley assumed that in
connection with the receipt of all the necessary governmental, regulatory or other approvals and consents required for the proposed transaction, no delays, limitations, conditions or restrictions
would be imposed that would have a material adverse effect on the contemplated benefits expected to be derived in the proposed transaction. Morgan Stanley is not a legal, tax, or regulatory advisor.

Summary of Financial Analyses of Morgan Stanley  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following is a summary of the material financial analyses performed by Morgan Stanley in connection with its oral opinion and the
preparation of its written opinion to the Ensco Board, each dated as of October&nbsp;6, 2018. The following summary is not a complete description of the financial analyses performed and factors
considered by Morgan Stanley in connection with its opinion, nor does the order of analyses described represent the relative importance or weight given to those analyses. Except as otherwise noted,
the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before October&nbsp;5, 2018, the most recent trading day prior to
Morgan Stanley's presentation to the Ensco Board of its financial analysis on October&nbsp;6, 2018. Some of these summaries of financial analyses include information presented in tabular format. In
order to fully understand the financial analyses used by Morgan Stanley, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of
the financial analyses. The analyses listed in the tables and described below must be considered as a whole. Assessing any portion of such analyses and of the factors reviewed, without considering all
analyses and factors, could create a misleading or incomplete view of the process underlying Morgan Stanley's opinion. Furthermore, mathematical analysis (such as determining the average or median) is
not in itself a meaningful method of using the data referred to below. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
performing the financial analyses summarized below and in arriving at its opinion, at the direction of the Ensco Board, Morgan Stanley utilized and relied upon certain financial
projections relating to Rowan and Ensco, each provided by the management of Ensco and which are described below. In addition, Morgan Stanley utilized and relied upon the number of issued and
outstanding shares of Rowan provided by management of Rowan. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
part of the financial projections, Ensco management provided, and Morgan Stanley relied upon with the consent of the Ensco Board, Ensco Management Case A and Ensco Management Case B
(the "Ensco financial forecasts"). Ensco management informed Morgan Stanley that Ensco Management Case A reflected a stronger market for offshore drilling rigs, including a more rapid day rate
recovery with higher terminal day rates, than Ensco Management Case B. The Ensco financial forecasts are more fully described in the section entitled "&#151;Certain Unaudited Financial
Forecasts Prepared by the Management of Ensco." </FONT></P>

Rowan Useful Life Discounted Cash Flow Analysis  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With respect to Rowan, Morgan Stanley calculated a range of implied total equity values of Rowan and values per Rowan ordinary share based on
(i)&nbsp;estimates of Rowan's future unlevered free cash flows from July&nbsp;1, 2018 through December&nbsp;31, 2050 (excluding ARO) and (ii)&nbsp;estimates of future unlevered free cash flows
from ARO from July&nbsp;1, 2018 through June&nbsp;30, 2059. Morgan Stanley performed this analysis on the estimated future unlevered free cash flows of each of Rowan (excluding ARO) and ARO
included in Ensco Management Case A and Ensco Management Case B. Morgan Stanley first calculated the estimated unlevered free cash flows (calculated as earnings before interest, taxes, and
depreciation and amortization, which is referred to in this section as EBITDA, less capital expenditures (including rig purchases) and unlevered taxes, plus proceeds from asset sales, and adjusted for
any changes in working capital and deferred expense) of each of Rowan (excluding ARO) and ARO. The projected unlevered free cash flows of each of Rowan (excluding ARO) and ARO were discounted to
June&nbsp;30, 2018 using discount rates ranging from 9.3% to 10.5% for the period between July&nbsp;1, 2018 through December&nbsp;31, 2025 based on Morgan Stanley's estimate of Rowan's weighted
average cost of capital ("WACC") for such period under both Ensco Management Case A and Ensco Management Case B. The projected unlevered cash flows of Rowan (excluding ARO) for the period from
January&nbsp;1, 2026 through December&nbsp;31, 2050, and for ARO the period from January&nbsp;1, 2026 through June&nbsp;30, 2059, were discounted to June&nbsp;30, 2018 using discount rates
ranging from 8.2% to 10.1% based on Morgan Stanley's estimate of Rowan's WACC for such period under both Ensco Management Case A and Ensco Management Case B. The range of discount rates used for such
period differed from that used for the period ending December&nbsp;31, 2025 as a result of an assumed repayment of certain senior notes of Rowan that are due in future years, resulting in an
adjustment to Rowan's debt-to-capitalization ratio. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With
respect to ARO, Morgan Stanley then deducted from the implied aggregate value ranges of ARO the estimated gross debt of ARO and added ARO's cash and cash equivalents as of
June&nbsp;30, 2018, resulting in the equity value of ARO. To arrive at the implied equity value of Rowan's 50% interest in
ARO, Morgan Stanley multiplied the equity value of ARO by 50% and added the value of a shareholder loan provided by Rowan to ARO (such resulting value, the "ARO DCF Value"). To arrive at the implied
equity value of Rowan, Morgan Stanley then (i)&nbsp;deducted from the implied aggregate value ranges of Rowan (excluding ARO) (A)&nbsp;the estimated gross debt of Rowan (excluding ARO) and
(B)&nbsp;the value of cash settled performance units of Rowan (excluding ARO) and (ii)&nbsp;added to the implied aggregate value ranges of Rowan (excluding ARO) (A)&nbsp;cash and cash
equivalents as of June&nbsp;30, 2018 of Rowan (excluding ARO) and (B)&nbsp;the ARO DCF Value. Aggregate values also included the then-current estimate of the value of capital spare parts of Rowan
as estimated by Ensco management. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based
on the above-described analysis, Morgan Stanley derived a range of implied values per share for Rowan as of June&nbsp;30, 2018 for each of Ensco Management Case A and Ensco
Management Case B of $25.39 to $33.30 and $14.38 to $20.17, respectively. </FONT></P>

unlevered free cash flows were discounted to June&nbsp;30, 2018 using discount rates ranging from 9.0% to 10.1% for the period between July&nbsp;1, 2018 through December&nbsp;31, 2025 based on
Morgan Stanley's estimate of Ensco's WACC for such period under both Ensco Management Case A and Ensco Management Case B, and the projected unlevered free cash flows for the period from

Management Case B based on Morgan Stanley's estimate of Ensco's WACC for such period. The range of discount rates used for such period differed from that used for the period ending December&nbsp;31,
2025 as a result of an assumed repayment of senior notes, resulting in an adjustment to Ensco's debt-to-capitalization ratio. The range of discount rates used for the period from January&nbsp;1,
2026 through December&nbsp;31, 2055 differed under Ensco Management Case A and Ensco Management Case B as a result of an assumed repayment of indebtedness under Ensco's credit facility under Ensco
Management Case A. Morgan Stanley then deducted from the implied aggregate value ranges Ensco's estimated gross debt and minority interest
and added Ensco's cash and cash equivalents as of June&nbsp;30, 2018. Aggregate values also included the then-current estimate of the value of capital spare parts of Ensco as estimated by Ensco
management. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based
on the above-described analysis, Morgan Stanley derived a range of implied values per Ensco ordinary share as of June&nbsp;30, 2018 for each of Ensco Management Case A and Ensco
Management Case B of $12.35 to $15.72 and $6.27 to $8.84, respectively. </FONT></P>

estimates by the management of Ensco. Morgan Stanley then calculated a terminal value range for each of Rowan (excluding ARO) and ARO by applying a multiple of aggregate value (defined as market
capitalization plus total debt and minority interests and less cash and cash equivalents) to estimated EBITDA for the twelve months ending June&nbsp;30, 2029 of 5.0x to 8.0x. This range was derived
based on Morgan Stanley's professional judgment after analyzing the aggregate value to NTM EBITDA multiple that Rowan ordinary shares had traded at from October&nbsp;5, 2013 to October&nbsp;5,
2018. The projected unlevered free cash flows for each of Rowan (excluding ARO) and ARO were discounted to June&nbsp;30, 2018 using discount rates ranging from 9.3% to 10.5% for the period from
July&nbsp;1, 2018 through December&nbsp;31, 2025 based on Morgan Stanley's estimate of Rowan's WACC for such period under both Ensco Management Case A and Ensco Management Case B, and the
projected unlevered free cash flows for the period from January&nbsp;1, 2026 through June&nbsp;30, 2028 and terminal value were discounted to June&nbsp;30, 2018 using discount rates ranging from
8.2% to 10.1% based on Morgan Stanley's estimate of Rowan's WACC for such period under both Ensco Management Case A and Ensco Management Case B. The range of discount rates used for such period

Morgan Stanley then deducted from the implied aggregate value ranges of ARO the estimated gross debt of ARO and added the cash and cash equivalents as of June&nbsp;30, 2018 of ARO, resulting in the
equity value of ARO. To arrive at the implied equity value of Rowan's 50% interest in ARO, Morgan Stanley multiplied the equity value of ARO by 50% and added the value of a shareholder loan provided
by Rowan to ARO (such resulting value, the "ARO 10-Year DCF Value"). To arrive at the implied equity value of Rowan, Morgan Stanley then (i)&nbsp;deducted from the implied aggregate value ranges of
Rowan (excluding ARO) (A)&nbsp;the estimated gross debt of Rowan (excluding ARO) and (B)&nbsp;the value of cash settled performance units of Rowan (excluding ARO) and (ii)&nbsp;added to the

Ensco 10-Year Discounted Cash Flow Analysis  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With respect to Ensco, Morgan Stanley calculated a range of implied total equity values of Ensco and values per Ensco ordinary share based on
estimates of future unlevered free cash flows for Ensco from July&nbsp;1, 2018 to June&nbsp;30, 2028. Morgan Stanley performed this analysis on the estimated future unlevered free cash flows
included in Ensco Management Case A and Ensco Management Case B. Morgan Stanley first calculated the estimated unlevered free cash flows (calculated as EBITDA, less capital expenditures (including rig
purchases) and unlevered taxes, plus proceeds from asset sales, and adjusted for any changes in working capital and deferred expense) of Ensco based on estimates by the management of Ensco. Morgan
Stanley then calculated a terminal value range for Ensco by applying a multiple of aggregate value to estimated EBITDA for the twelve months ending June&nbsp;30, 2029 of 5.0x to 8.0x. This range was
derived based on Morgan Stanley's professional judgment after analyzing the aggregate value to NTM EBITDA multiple that Ensco ordinary shares had traded at from October&nbsp;5, 2013 to
October&nbsp;5, 2018. The projected unlevered free cash flows were discounted to June&nbsp;30, 2018 using discount rates ranging from 9.0% to 10.1% for the period from July&nbsp;1, 2018 through
December&nbsp;31, 2025 based on Morgan Stanley's estimate of Ensco's WACC for such period under both Ensco Management Case A and Ensco Management Case B, and the projected unlevered free cash flows
for the period from January&nbsp;1, 2026 through June&nbsp;30, 2028 and terminal value were discounted to June&nbsp;30, 2018 using discount rates ranging from 8.7% to 10.3% in Ensco Management
Case A and 8.8% to 10.3% in Ensco Management Case B based on Morgan Stanley's estimate of Ensco's WACC </FONT></P>

resulted in a range of per Ensco ordinary share values of $13.39 to $17.07 for Ensco Management Case A and $7.76 to $10.58 for Ensco Management Case B. These ranges compared with ranges of implied
values per Ensco ordinary share on a standalone basis for each of Ensco Management Case A and Ensco Management Case B of $12.35 to $15.72 and $6.27 to $8.84, respectively. </FONT></P>

Analysis of Precedent Premia in Shared Governance Transactions  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan Stanley reviewed, based on publicly available information, the premiums paid in selected shared governance transactions. Morgan Stanley
considered premiums paid in the following transactions, which involved transactions since 1995 in which the consideration was stock and which had a transaction value of $1.0&nbsp;billion or more and
in which (1)&nbsp;the acquiring company shareholders retained ownership of between 60% and 70% in the combined company and (2)&nbsp;the target achieved significant board representation and
management positions in the combined company (including by target personnel becoming either the chief executive officer or chairman of the combined company): </FONT></P>

Stanley noted that the mean and median premiums paid in the transactions reviewed were approximately 14% and 15%, respectively, over the unaffected closing share price of the
target. Based on this analysis and its professional judgement, Morgan Stanley selected a reference premium range of 10% to 20% to apply to Rowan's closing share price on October&nbsp;5, 2018 of
$18.78, which implied a range of $20.66 to $22.54 per Rowan ordinary share. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan
Stanley then calculated the exchange ratio range implied by the precedent premia analysis. Morgan Stanley compared the low end of the implied precedent premia range for Rowan
ordinary shares to the current price of Ensco ordinary shares as of October&nbsp;5, 2018, to derive the lowest exchange ratio implied by the precedent premia analysis. Similarly, Morgan Stanley
compared the high end of the implied precedent premia range for Rowan ordinary shares to the current price of Ensco ordinary shares as of October&nbsp;5, 2018, to derive the highest exchange ratio
implied by the precedent premia analysis. The implied exchange ratio range resulting from the analysis was 2.44x to 2.66x. Morgan Stanley noted that the transaction agreement provided for an exchange

Equity Research Analysts' Price Targets  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan Stanley reviewed publicly available equity research analysts' 12-month share price targets for Rowan ordinary shares and Ensco ordinary
shares. Morgan Stanley noted that the price targets issued by those research analysts with publicly available price targets ranged from $11.00 to $30.00 per Rowan ordinary share and $4.00 to $11.50
per Ensco ordinary share. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan
Stanley then calculated the exchange ratio range implied by the analysts' target prices. For each equity research analyst that published a 12-month share price target for both
Rowan ordinary shares and Ensco ordinary shares, Morgan Stanley calculated the implied exchange ratio by dividing each equity research analyst's 12-month share price target for Rowan ordinary shares
by their corresponding 12-month share price target for Ensco ordinary shares. Morgan Stanley then observed the lowest and highest implied exchange ratio to derive an implied exchange ratio reference
range of 1.88x to 3.27x. Morgan Stanley noted that the transaction agreement provided for an exchange ratio of 2.215x. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
public market trading price targets published by equity research analysts do not necessarily reflect the current market trading prices for Rowan ordinary shares or Ensco ordinary
shares, and these estimates are subject to uncertainties, including the future financial performance of Rowan and Ensco as well as future market conditions. </FONT></P>

Historical Trading Prices  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan Stanley reviewed the historical trading prices of Rowan ordinary shares and Ensco ordinary shares during the 52&nbsp;week period ended
October&nbsp;5, 2018, which reflected low to high intra-day prices for Rowan ordinary shares during such period of $10.94 to $19.30 per share and Ensco ordinary shares of $4.10 to $8.74 per share
during such period. Morgan Stanley then calculated the exchange ratio implied by the share price range for Rowan and Ensco during the 52&nbsp;week period. Morgan Stanley compared the lowest
intra-day price for Rowan ordinary shares to the highest intra-day price for Ensco ordinary shares to derive the lowest exchange ratio implied by the historical trading prices during the
52&nbsp;week period ended October&nbsp;5, 2018. Similarly, Morgan Stanley compared the
highest intra-day price for Rowan ordinary shares to the lowest intra-day price per Ensco ordinary share to derive the highest exchange ratio implied by the historical trading prices during the
52&nbsp;week period ended October&nbsp;5, 2018. The implied exchange ratio reference range resulting from this analysis was 1.25x to 4.71x. Morgan Stanley noted that the transaction agreement
provided for an exchange ratio of 2.215x. </FONT></P>

Contribution Analysis  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan Stanley performed a relative contribution analysis of Rowan and Ensco, in which Morgan Stanley reviewed selected operational data based
on Ensco management forecasts and street estimates for each of Rowan and Ensco, to determine Rowan's and Ensco's relative contribution to the combined company following the transaction. In particular,
Morgan Stanley analyzed the relative contribution to net asset value, revenue, EBITDA and unlevered free cash flow (defined as EBITDA minus capital expenditures). The net asset values used were based
on (i)&nbsp;street estimates and (ii)&nbsp;the Ensco Management Case A and Ensco Management Case B useful life unlevered discounted cash flow valuations (see "&#151;Useful Life Discounted
Cash Flow Analysis"), while the revenue, EBITDA and unlevered free cash flow estimates were based on Ensco Management Case A and Ensco Management Case B. For purposes of the contribution analysis,
Rowan's financials were adjusted to include 50% of ARO's reported revenue, EBITDA and unlevered free cash flow, as applicable. The foregoing analyses indicated a range of relative contributions from
53%/47% (Ensco to Rowan) on the low end to 74%/26% (Ensco to Rowan) on the high end, in each case excluding synergies. Including synergies (based on assumed run-rate synergies of $150&nbsp;million,
as directed by Ensco management) as a component of the contribution analysis, the foregoing analyses indicated a range of relative contributions from 45%/39%/16% (Ensco to Rowan to synergies) on the
low end to 58%/26%/16% (Ensco to Rowan to synergies) on the high end. </FONT></P>

Illustrative Transaction Value Creation Analysis  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan Stanley performed an illustrative transaction value creation analysis, the purpose of which is to review the implied increase in market
value to the Ensco shareholders based on assumptions regarding synergies and pro forma ownership of the combined company. The illustrative transaction value creation analysis was performed for
illustrative purposes only and is not indicative of actual trading levels and does not take into account the timing to achieve any synergies or the timing of the closing of the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
its illustrative analysis, Morgan Stanley first calculated the then-current equity market value of Ensco as of the close of trading on October&nbsp;5, 2018, which resulted in a
value of approximately $3.8&nbsp;billion. Morgan Stanley then calculated the then-current equity market value of Rowan as of the close of trading on October&nbsp;5, 2018, which resulted in a value
of approximately $2.4&nbsp;billion. Morgan Stanley then noted that the exchange ratio set forth in the transaction agreement of 2.215x implied a pro forma ownership of approximately 39% of the
combined company by Rowan shareholders and approximately 61% by Ensco shareholders, using market prices on October&nbsp;5, 2018, and thus, Rowan shareholders would hypothetically receive
approximately 39% of the then-current market value of Ensco and Ensco shareholders would hypothetically receive approximately 61% of the then-current market value of Rowan. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan
Stanley also noted that based on the implied fully-diluted pro forma ownership, Rowan shareholders would hypothetically receive approximately 39% of any increase in market value
from synergies in connection with the transaction while Ensco shareholders would hypothetically receive approximately 61% of any increase in market value from synergies in connection with the
transaction. For purposes of this analysis, Morgan Stanley assumed run-rate synergies of $150&nbsp;million, as directed by Ensco management. The present value of these synergies was calculated by
discounting the estimated future cash flows from synergies, net of costs to achieve, to June&nbsp;30, 2018, using a discount </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In connection with the review of the transaction agreement and the transactions contemplated thereby by the Ensco Board, Morgan Stanley
performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not necessarily susceptible to a
partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis
or factor it considered. Morgan Stanley believes that selecting any portion of its analyses, without considering all analyses as a whole, would create an incomplete view of the process underlying its
analyses and opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less
probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis described above should not be taken to be Morgan Stanley's view of the actual value of
Rowan or Ensco. In performing its analyses, Morgan Stanley made numerous assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters,
many of which are beyond the control of Rowan or Ensco. These include, among other things, the impact of competition on Rowan's and Ensco's businesses and the industry generally, industry growth, and
the absence of any adverse material change in the financial condition and prospects of Rowan or Ensco, or the industry, or in the financial markets in general. Any estimates contained in Morgan
Stanley's analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan
Stanley conducted the analyses described above solely as part of its analysis of whether the exchange ratio pursuant to the transaction agreement was fair from a financial point
of view to Ensco and in connection with the delivery of its opinion, dated October&nbsp;6, 2018, to the Ensco Board. These analyses do not purport to be appraisals or to reflect the prices at which
Rowan ordinary shares or Ensco ordinary shares might actually trade. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
exchange ratio was determined through arm's-length negotiations between Rowan and Ensco and was approved by the Ensco Board. Morgan Stanley provided advice to Ensco during these </FONT></P>

Morgan Stanley did not, however, recommend any specific exchange ratio to Ensco, nor that any specific exchange ratio constituted the only appropriate exchange ratio for the transaction.
Morgan Stanley's opinion did not address the relative merits of the transaction as compared to any other alternative business transaction, or other alternatives, or whether or not such alternatives
could be achieved or are available. In addition, Morgan Stanley's opinion was not intended to, and did not, in any manner, address the price at which the Ensco ordinary shares would trade following
the transaction or at any time, and Morgan Stanley expressed no opinion or recommendation to any holder of Ensco ordinary shares or Rowan ordinary shares as to how such holder should vote at the Ensco
general meeting or the Rowan Court meeting and Rowan general meeting, respectively, or whether to take any other action with respect to the transaction. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan
Stanley's opinion and its oral presentation to the Ensco Board was one of many factors taken into consideration by the Ensco Board in deciding to approve the transaction agreement
and the transactions contemplated thereby. Consequently, the analyses as described above should not be viewed as determinative of the opinion of the Ensco Board with respect to the exchange ratio
pursuant to the transaction agreement or of whether the Ensco Board would have been willing to agree to a different exchange ratio. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Morgan
Stanley's opinion was approved by a committee of Morgan Stanley investment banking and other professionals in accordance with Morgan Stanley's customary practice. Morgan Stanley
is a global financial services firm engaged in the securities, investment management and individual wealth management businesses. Its securities business is engaged in securities underwriting,
trading, hedging and brokerage activities, foreign exchange, commodities and derivatives trading, prime brokerage, as well as providing investment banking, financing and financial advisory services.
Morgan Stanley, its affiliates, directors and officers may at any time invest on a principal basis or manage funds that invest, hold long or short positions, finance positions, and may trade or
otherwise structure and effect transactions, for its own account or the accounts of its customers, in debt or equity securities or loans of Ensco, Rowan or any other company, or any currency or
commodity or instrument, that may be involved in the transaction, or any related derivative instrument. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
the terms of its engagement letter, Morgan Stanley provided the Ensco Board with financial advisory services and a financial opinion described in this section and attached as
Annex&nbsp;B to this joint proxy statement in connection with the transaction, and Ensco has agreed to pay Morgan Stanley a fee, upon rendering its fairness opinion, of $2&nbsp;million payable
upon the earlier of the closing of the transaction or the termination of the transaction agreement. If the transaction is concluded, Ensco has agreed to pay Morgan Stanley a transaction fee of
$9&nbsp;million (less any fee that has been previously paid), which is payable upon and is contingent upon the consummation of the transaction. Ensco has also agreed to reimburse Morgan Stanley for
its expenses incurred in performing its services. In addition, Ensco has agreed to indemnify Morgan Stanley and its affiliates, their respective officers, directors, employees and agents and each
other person, if any, controlling Morgan Stanley or any of its affiliates against certain liabilities and expenses, including certain liabilities under the federal securities laws, relating to or
arising out of Morgan Stanley's engagement. Ensco also retained Citigroup Global Markets&nbsp;Inc. and HSBC&nbsp;Securities (USA)&nbsp;Inc. as co-financial advisors to provide financial advisory
services to Ensco's management related to the potential transaction with Rowan following the transaction and agreed to pay each such advisor $2.5&nbsp;million upon the consummation of the
transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
the two years prior to the date of Morgan Stanley's opinion, in addition to the services provided in connection with the transaction and the opinion, Morgan Stanley provided financial
advisory and financing services to Ensco and its affiliates and received aggregate fees of between $5&nbsp;million and $10&nbsp;million in connection with such services. Morgan Stanley is also a
lender under Ensco's revolving credit facility. During the same period, Morgan Stanley provided financing services to Rowan and its affiliates and received aggregate fees of less than
$1&nbsp;million. Morgan Stanley may seek to provide financial advisory and financing services to Rowan, Ensco and their respective affiliates in the future and would expect to receive fees for the
rendering of those services. </FONT></P>

Opinion of Financial Advisor to Rowan  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Goldman Sachs rendered its opinion to the Rowan Board that, as of October&nbsp;7, 2018 and based upon and subject to the factors and

view to the holders of the Rowan ordinary shares (other than Ensco and its affiliates), as of the date of the opinion, of the exchange ratio pursuant to the transaction agreement. Goldman Sachs'
opinion does not express any view on, and does not address, any other term or aspect of the transaction agreement or the transaction or any term or aspect of any other agreement or instrument

employees of Rowan, or class of such persons, in connection with the transaction, whether relative to the exchange ratio pursuant to the transaction agreement or otherwise. Goldman Sachs does not
express any opinion as to the prices at which the Ensco ordinary shares will trade at any time or as to the impact of the transaction on the solvency or viability of Rowan or Ensco or the ability of
Rowan or Ensco to pay their respective obligations when they come due. Goldman Sachs' opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the
information made available to it as of, the date of the opinion and Goldman Sachs assumed no responsibility for updating, revising or reaffirming its opinion based on circumstances, developments or

discounted cash flow analysis of Rowan to derive a range of implied values per Rowan ordinary share as of June&nbsp;30, 2018. Using discount rates ranging from 9.50% to 10.50%, reflecting estimates
of Rowan's weighted average cost of capital, Goldman Sachs discounted to present value as of June&nbsp;30, 2018 (i)&nbsp;estimates of unlevered free cash flow for Rowan for July&nbsp;1, 2018
through December&nbsp;31, 2023 as reflected in the Rowan Forecasts and (ii)&nbsp;a range of illustrative terminal values for Rowan, which were calculated by applying an illustrative terminal value
to EBITDA multiple range of 5.5x to 7.5x to estimated terminal year EBITDA for Rowan, which estimated terminal year EBITDA was reflected in the Rowan Forecasts (this analysis implied a range of
perpetuity growth rates of (2.1)% to 1.7%). Goldman Sachs derived such range of discount rates by application of the Capital Asset Pricing Model, which requires certain company-specific inputs,
including the company's target capital structure weightings, the cost of long-term debt, after-tax yield on permanent excess cash, if any, future applicable marginal cash tax rate and a beta for the
company, as well as certain financial metrics for the United States financial markets generally. The illustrative terminal value to EBITDA multiple range for Rowan was derived by Goldman Sachs using
its professional judgment and experience, taking into account, among other things, EBITDA multiples implied by Rowan's trading prices (and estimates of next-twelve-months EBITDA as reported by IBES)
over certain prior periods. Goldman Sachs derived a range of illustrative enterprise values for Rowan by adding the range of present values it derived above. Goldman Sachs then subtracted from the
range of illustrative enterprise values it derived for Rowan the amount of Rowan's net debt as of June&nbsp;30, 2018, as provided by the management of Rowan, and added to such range an illustrative
value for Rowan's ownership interest in ARO as of June&nbsp;30, 2018, calculated using the Rowan Forecasts, to derive a range of illustrative equity values for Rowan. Goldman Sachs then divided the
range of illustrative equity values it derived by the number of fully diluted outstanding Rowan ordinary shares, as provided by the management of Rowan, to derive a range of illustrative values per
Rowan Ordinary share ranging from $12.70 to $20.38. </FONT></P>

exchange ratio was determined through arm's-length negotiations between Rowan and Ensco and was approved by the Rowan Board. Goldman Sachs provided advice to Rowan during these
negotiations. Goldman Sachs did not, however, recommend any specific exchange ratio to Rowan or the Rowan Board or that any specific exchange ratio constituted the only appropriate exchange ratio for
the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
described above, Goldman Sachs' opinion to the Rowan Board was one of many factors taken into consideration by the Rowan Board in making its determination to approve the transaction

by the transaction agreement. Goldman Sachs acted as financial advisor to Rowan in connection with, and participated in certain of the negotiations leading to, the transaction contemplated by the
transaction agreement. Goldman Sachs has provided certain financial advisory and/or underwriting services to Rowan and/or its affiliates from time to time for which the Investment Banking Division of
Goldman Sachs has received, and may receive, compensation, including having acted as financial advisor to Rowan in connection with the formation of ARO in November 2016 and as joint book runner with
respect to Rowan's offering of 7.375% senior unsecured notes due 2025 (aggregate principal amount $500,000,000) in December 2016. During the two-year period ended October&nbsp;7, 2018, Goldman Sachs
has recognized compensation for financial advisory and/or underwriting services provided by its Investment Banking Division to Rowan and/or its affiliates of approximately $5.4&nbsp;million. During
the two-year period ended October&nbsp;7, 2018, the Investment Banking Division of Goldman Sachs has not been engaged by Ensco or its affiliates to provide financial advisory or underwriting
services for which Goldman Sachs has recognized compensation. Goldman Sachs may also in the future provide financial advisory and/or underwriting services to Rowan, Ensco and their respective
affiliates for which the Investment Banking Division of Goldman Sachs may receive compensation. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Rowan Board selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions
similar to the transaction. Pursuant to a letter agreement dated June&nbsp;18, 2018, Rowan engaged Goldman Sachs to act as its financial advisor in connection with the contemplated transaction. The
engagement letter between Rowan and Goldman Sachs provides for a transaction fee of $19,000,000, $2,000,000 of which became payable at announcement of the transaction, and the remainder of which is
contingent upon consummation of the transaction. In addition, Rowan has agreed to reimburse Goldman Sachs for certain of its expenses, including attorneys' fees and disbursements, and to indemnify
Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws. </FONT></P>

Certain Unaudited Financial Forecasts Prepared by the Management of Ensco  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For internal planning purposes and in connection with the proposed transaction, Ensco's management prepared forecasts of expected future
financial and operating performance of Ensco (as used in this section, the "Ensco financial forecasts"), of Rowan (excluding ARO) (as used in this section, the "Rowan standalone financial forecasts")
and of ARO (as used in this section, the "ARO financial forecasts" and, together with the Rowan standalone financial forecasts, the "Rowan financial forecasts"). These forecasts were for multiple
years and consisted of two cases, Ensco Management Case A and Ensco Management Case B, with Ensco Management Case A reflecting a stronger market for offshore drilling rigs, including a more rapid day
rate recovery with higher terminal day rates, than Ensco Management Case B. Select material line items for certain periods from the Ensco financial forecasts and the Rowan financial forecasts, as well
as material operating assumptions underlying such forecasts, are set forth below. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
primary market assumptions underlying the discounted cash flow analysis for each of Ensco Management Case A and Ensco Management Case B included the anticipated period during which
utilization and day rates associated with Ensco's/Rowan's/ARO's jackups and floaters would improve. For Ensco Management Case A, Ensco assumed (i)&nbsp;utilization recovery beginning in 2018
followed by day rate recovery in 2019 for jackups, and (ii)&nbsp;utilization recovery beginning in 2019 with gradual day rate recovery in 2019 leading to material day rate recovery in 2020 for
floaters. For Ensco Management Case B, Ensco assumed (i)&nbsp;utilization recovery beginning in 2018 with gradual day rate recovery in 2019 leading to material day rate recovery in 2020 for jackups,
and (ii)&nbsp;utilization recovery beginning in 2019 with gradual day rate recovery in 2019 and 2020 leading to material day rate recovery in 2021 for floaters. Ensco Management Case A also included
a post-recovery day rate assumption that is 10-15% higher than Ensco Management Case B for both jackups and floaters. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Ensco financial forecasts and the Rowan financial forecasts were based on a variety of assumptions and estimates. The assumptions and estimates underlying such forecasts may not be
realized and are inherently subject to significant business, economic and competitive uncertainties and contingencies, all of which are difficult to predict and many of which are beyond Ensco's and
Rowan's control. The assumptions and estimates used to create the Ensco financial forecasts and the Rowan financial forecasts involve judgments made with respect to, among other things, revenue
growth, drilling activity in the oil and gas sector, future supply, demand and prices of commodities including crude oil and natural gas, general domestic and foreign economic, regulatory and
political conditions, levels of operating expenses and matters specific to the businesses of Ensco and Rowan, all of which are difficult to predict and many of which are outside of Ensco's and Rowan's
control. The Ensco financial forecasts and the Rowan financial forecasts also reflect assumptions as to certain business decisions that are subject to change and that do not reflect any of the effects
of the transaction, or any other changes that may in the future affect Ensco, Rowan or their assets, business, operations, properties, policies, corporate structure, capitalization and management as a
result of the transaction or otherwise. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
inclusion of the Ensco financial forecasts and the Rowan financial forecasts in this joint proxy statement should not be regarded as an indication that Ensco or any of its advisors
or representatives considered or consider such forecasts to be an accurate prediction of future events or that such forecasts will be achieved, and the Ensco financial forecasts and the Rowan
financial forecasts should not be relied upon as such. None of Ensco, Rowan or their respective advisors or representatives has made or makes any representation regarding the information contained in
the Ensco financial forecasts or the Rowan financial forecasts, and, except as may be required of Ensco or Rowan by applicable securities laws, none of them intends to update or otherwise revise or
reconcile such forecasts to reflect circumstances existing after the date they were generated or to reflect the occurrence of future events even in the event that any or all of the assumptions
underlying the Ensco financial forecasts or the Rowan financial forecasts are shown to be in error. </FONT></P>

Summary of Ensco Financial Forecasts and Rowan Financial Forecasts Prepared by Ensco  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Ensco financial forecasts and Rowan financial forecasts include projected information at the individual rig level and consolidated financial
projections through the remaining useful life of the existing Ensco, Rowan (excluding ARO) and ARO fleets (through 2055, 2050 and 2059, respectively). However, Ensco believes that operating
assumptions beyond a six-year period (beyond 2023) may not be meaningful to current and potential shareholders because such information becomes less predictive with each successive year. As a result,
Ensco did not develop discrete operating
assumptions beyond a six-year period, and the tables below present summaries of select material line items and material operating assumptions with respect to (a)&nbsp;in the case of the Ensco

Certain Unaudited Financial Forecasts Prepared by the Management of Rowan  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For internal planning purposes and in connection with the proposed transaction, Rowan's management prepared forecasts of expected future
financial and operating performance of Rowan (as used in this section, the "Rowan standalone financial forecasts"), of ARO (as used in this section, the "ARO financial forecasts" and, together with
the Rowan standalone financial forecasts, the "Rowan financial forecasts"), and of Ensco (as used in this section, the "Ensco financial forecasts"). These forecasts were for multiple years. Select

<P style="font-family:times;"><FONT SIZE=2>forecasts
and the Rowan financial forecasts, as well as material operating assumptions underlying such forecasts, are set forth below. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
primary market assumptions underlying the forecasts included the anticipated period during which utilization and day rates associated with Rowan's/ARO's/Ensco's jackups and floaters
would improve. Rowan assumed (i)&nbsp;utilization recovery beginning in 2018 followed by day rate recovery in 2019 for jackups, and (ii)&nbsp;utilization recovery beginning in 2019 with gradual
day rate recovery in 2019 leading to more material day rate recovery in 2020 and 2021 for floaters. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Rowan financial forecasts and the Ensco financial forecasts were based on a variety of assumptions and estimates. The assumptions and estimates underlying such forecasts may not be
realized and are inherently subject to significant business, economic and competitive uncertainties and contingencies, all of which are difficult to predict and many of which are beyond Rowan's and
Ensco's control. The assumptions and estimates used to create the Rowan financial forecasts and the Ensco financial forecasts involve judgments made with respect to, among other things, revenue
growth, drilling activity in the oil and gas sector, future supply, demand and prices of commodities including crude oil and natural gas, general domestic and foreign economic, regulatory and
political conditions, levels of operating expenses and matters specific to the businesses of Rowan and Ensco, all of which are difficult to predict and many of which are outside of Rowan's and Ensco's
control. The Rowan financial forecasts and the Ensco financial forecasts also reflect assumptions as to certain business decisions that are subject to change and that do not reflect any of the effects
of the transaction, or any other changes that may in the future affect Rowan, Ensco or their assets, business, operations, properties, policies, corporate structure, capitalization and management as a
result of the transaction or otherwise. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
management of Rowan, after discussions with Ensco, also estimated the timing and amount of projected realization of annual savings from pre-tax cost synergies for the combined
company (sometimes referred to as the "Rowan Synergies"), as well as the cost to achieve the Rowan Synergies. The Rowan Synergies are not reflected in the Rowan financial forecasts or the Ensco
financial forecasts. In addition, the management of Rowan prepared certain projections of future financial and operating performance of the combined company for the six months ending
December&nbsp;31, 2018 and each fiscal year during the period from 2019 through 2023 by combining the Rowan financial forecasts, the Ensco financial forecasts and the Rowan Synergies, and making
certain adjustments for the cost structure of the combined company as well as other adjustments compared to the standalone Ensco financial forecasts (such projections, as so adjusted, are sometimes
referred to as the "Combined Company financial forecasts"). We sometimes refer to all of the forecasts and synergies described above as the "forward-looking financial information." </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
inclusion of the forward-looking financial information in this joint proxy statement should not be regarded as an indication that Rowan or any of its advisors or representatives
considered or consider such forecasts to be an accurate prediction of future events or that such forecasts will be achieved, and the forward-looking financial information should not be relied upon as
such. None of Rowan, Ensco or
their respective advisors or representatives has made or makes any representation regarding the information contained in the forward-looking financial information, and, except as may be required of
Rowan or Ensco by applicable securities laws, none of them intends to update or otherwise revise or reconcile such forecasts to reflect circumstances existing after the date they were generated or to
reflect the occurrence of future events even in the event that any or all of the assumptions underlying the forward-looking financial information are shown to be in error. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Rowan
and Ensco shareholders are cautioned not to place undue reliance on the forward-looking financial information included in this joint proxy statement, and such forward-looking
financial information should not be regarded as an indication that Rowan, the Rowan Board or any other person considered, or now considers, them to be reliable predictions of future results, and they
should not be relied upon as such. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Although
presented with numerical specificity, the forward-looking financial information is not fact and reflects numerous assumptions, estimates and judgments as to future events and
the probability of such events made by Rowan's management, including the assumptions, estimates and judgments noted below. Since the forward-looking financial information covers multiple years, such
information by its nature becomes less predictive with each successive year. There can be no assurance that the assumptions, estimates and judgments used to prepare the forward-looking financial
information will prove to be accurate, and actual results may differ materially from those contained in such forecasts. The forward-looking financial information constitutes forward-looking
statements. Please see "Cautionary Statement Regarding Forward-Looking Statements." </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
forward-looking financial information included in this joint proxy statement has been prepared by, and is the responsibility of, Rowan's management. Rowan does not as a matter of
course make public projections as to future sales, earnings, or other results. However, the management of Rowan has prepared the forward-looking financial information set forth below to present the
financial information made available, in whole or in part, to the Rowan Board, Ensco (only in the case of the Rowan financial forecast for the years ending December&nbsp;31, 2019, 2020, 2021, 2022
and 2023) and Rowan's financial advisor, Goldman Sachs, in connection with their respective evaluations of the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Neither
Rowan's independent auditors, nor any other independent accountants, have compiled, examined, or performed any procedures with respect to the forward-looking financial
information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any
association with, the forward-looking financial information. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition to being used by the Rowan Board in connection with its deliberations regarding the transaction, the forward-looking financial information was provided to Goldman Sachs. The
Rowan financial forecasts for only the years ending December&nbsp;31, 2019, 2020, 2021, 2022 and 2023 were provided to Ensco and Morgan Stanley. The Rowan financial forecasts, Rowan Synergies and
Combined Company financial forecasts were prepared for use only by the Rowan Board, Rowan, Goldman Sachs and, with respect to the Rowan financial forecasts for the years ending December&nbsp;31,
2019, 2020, 2021, 2022 and 2023, Ensco and Morgan Stanley. The Ensco financial forecasts were prepared for use only by the Rowan Board, Rowan and Goldman Sachs. </FONT></P>

Ensco Rowan Corporate Governance Policy  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Immediately following the Scheme Effective Time, Ensco will adopt the Ensco Rowan Corporate Governance Policy. The Ensco Rowan Corporate
Governance Policy establishes the Ensco Rowan Board positions of Executive Chairman and Independent Lead Director, whereas Ensco's current Corporate Governance Policy provides for only an independent
chairperson. For so long as the chairman of the Ensco Rowan Board is an Executive Chairman, the Ensco Rowan Board will be required to appoint an Independent Lead Director. In the event the Ensco Rowan
Board appoints a non-executive chairman, the role of Independent Lead Director will be combined with the non-executive Chairman. For additional information regarding the size of the Ensco Rowan Board
following the Scheme Effective Time and Rowan and Ensco's director designation rights, see "&#151;Board of Directors and Executive Officers of Ensco Rowan&nbsp;plc Following the Transaction." </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Ensco Rowan Corporate Governance Policy provides that the Executive Chairman's responsibilities will include, among other things, leading the Ensco Rowan Board, overseeing
evaluations, scheduling board meetings and setting meeting agendas, developing standards for the information submitted to the board, providing assurance and oversight of the integration and synergy
plan of the combined company, advising the Chief Executive Officer regarding talent integration and customer and investor relations support. The Ensco Rowan Corporate Governance Policy also provides
that the Independent Lead Director's responsibilities will include assisting and advising the Executive Chairman as to scheduling board meetings, setting board meeting agendas in concert with the
Executive Chairman and Chief Executive Officer, developing standards for the information submitted to the board for executive sessions of the independent directors, developing agendas for and serving
as chairman of executive
sessions of the independent directors, serving as principal liaison among the independent directors, Chief Executive Officer and Executive Chairman in respect of issues discussed at executive sessions
of the independent directors and serving as Chairman of Ensco Rowan Board meetings when the Executive Chairman is not present. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition to changing the leadership positions of the Ensco Rowan Board, the Ensco Rowan Corporate Governance Policy also adds certain requirements of the Ensco Rowan Board that will
continue for up to two years following the Scheme Effective Time unless amended, modified or terminated by unanimous vote of the Ensco Rowan Board. Such unanimous approval of the Ensco Rowan Board is
required for, among other things, amendments to the employment agreements of Dr.&nbsp;Burke and Mr.&nbsp;Towell during the two-year and 18-month periods, respectively, following the Scheme
Effective Time. In addition, if the Nominating and Governance Committee of the Ensco Rowan Board, by unanimous vote, determines not to renominate any Ensco or Rowan designee, then such designee shall
not be renominated. If such designee is a member of the Nominating and Governance Committee of the Ensco Rowan Board, then a unanimous vote of every other member of such committee and the unanimous
vote of the Ensco Rowan Board other than such designee is required to not nominate such designee for re-election. </FONT></P>

Accounting Treatment of the Transaction  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco prepares its financial statements in accordance with GAAP. The transaction will be accounted for using the acquisition method of
accounting with Ensco being considered the acquirer of Rowan for accounting purposes. This means that Ensco will allocate the purchase price to the fair value of Rowan's tangible and intangible assets
and liabilities at the acquisition date, with the excess purchase price, if any, being recorded as goodwill, or the excess of the fair value of Rowan's tangible and intangible assets and liabilities
at the acquisition date over the purchase price, if any, being recognized in Ensco's earnings. Under the acquisition method of accounting, goodwill is not amortized but is tested for impairment at
least annually. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Ensco ordinary shares to be received by Rowan shareholders in connection with the transaction will not be registered under the Securities
Act or the securities laws of any state of the United States and will be issued in reliance upon the exemption from registration provided by Section&nbsp;3(a)(10) of the Securities Act and
exemptions from or qualifications under the registration requirements under the securities laws of applicable states of the United States. Section&nbsp;3(a)(10) of the Securities Act exempts the
issuance of any securities issued in exchange for one or more bona fide outstanding securities, or partly in such exchange and partly for cash, from the registration requirements of the Securities
Act, where the terms and conditions of the issuance and exchange of such securities have been approved by a court of competent jurisdiction that is expressly authorized by law to grant such approval,
after a hearing upon the substantive and procedural fairness of the terms and conditions of such issuance and exchange at which all persons to whom it is proposed to issue the securities have the
right to appear and have received timely and adequate notice thereof. The Court is authorized to conduct a hearing at which the fairness of the terms and conditions of the Scheme of Arrangement will
be considered. Accordingly, the Court order will, if granted, constitute a basis for the exemption from the registration requirements of the Securities Act provided by Section&nbsp;3(a)(10) thereof
with respect to the Ensco ordinary shares to be received by Rowan shareholders in exchange for their
Rowan ordinary shares and the issuance of the Ensco ordinary shares pursuant to the Scheme of Arrangement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The information set forth in the table below is intended to comply with Item&nbsp;402(t) of the SEC's Regulation&nbsp;S-K, which requires
disclosure of information about certain compensation for each named executive officer of Rowan that is based on, or otherwise relates to, the transaction, which is referred to as the
transaction-related compensation. For additional details regarding the terms of the payments and benefits described below, see the section entitled "&#151;Rowan's Directors and Officers Have
Financial Interests in the Transaction" above. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
amounts shown in the table below are estimates based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including the assumptions
described below and in the footnotes to the table, and do not reflect certain compensation actions that may occur before completion of the transaction. For purposes of calculating such amounts, the
following assumptions were used:</FONT></P>

the sum of&nbsp;(i)&nbsp;the respective executive's base salary, plus (ii)&nbsp;the greater of the respective executive's three year average actual payout of Rowan's annual incentive plan or

Quantification of Potential Payments and Benefits to Ensco's Named Executive Officers in Connection
with the Transaction  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The information set forth in the table below is intended to comply with Item&nbsp;402(t) of the SEC's Regulation&nbsp;S-K, which requires
disclosure of information about certain compensation for each current named executive officer of Ensco who will be entering into an agreement with Ensco that is based on, or otherwise relates to, the
transaction, which is referred to as the transaction-related compensation. For additional details regarding the terms of the payments and benefits described below, see the section entitled
"&#151;Ensco's Directors and Officers Have Financial Interests in the Transaction" above. The information set forth herein is solely intended to comply with Item&nbsp;402(t) and does not
reflect any decisions taken with regard to individuals who will serve as the executive officers of the combined company following the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
amounts shown in the table below are estimates based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including the assumptions
described below and in the footnotes to the table, and do not reflect certain compensation actions that may occur before completion of the transaction. For purposes of calculating such amounts, the
following assumptions were used:</FONT></P>

be those providing for severance payments and benefits as described above in "Ensco's Directors and Officers Have Financial Interests in the Transaction&#151;Severance Payments and Benefits." </FONT> <FONT SIZE=2>

(iv)&nbsp;&pound;1,237,500 representing an estimate of the payment of awards under the Ensco International Incorporated 2018 Cash Incentive Plan for the periods up to the end of the
eighteen-month term of the Trowell Employment Agreement. For purposes of this section, amounts were converted to U.S.&nbsp;dollars using an exchange rate of 1.3042 U.S.&nbsp;dollars for each

retention award agreements provide for accelerated vesting upon a "double trigger" qualifying termination. We have assumed that the named executive officers will experience a termination without cause

Terms of the Transaction  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The transaction will be implemented by way of a Scheme of Arrangement. The transaction agreement provides that, subject to the terms and
conditions of the transaction agreement, at the Scheme Effective Time, each Rowan shareholder who is a Scheme Shareholder will be entitled to receive 2.215 Ensco ordinary shares for each Rowan
ordinary share owned by such Rowan shareholder that is subject to the Scheme of Arrangement. See "&#151;Consideration to Be Received in the Transaction." </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
rights of Ensco shareholders after the completion of the transaction, including the former Rowan shareholders who have received the transaction consideration, will be governed by the
Ensco Articles of Association. </FONT></P>

Scheme Effective Time and Closing of the Transaction  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Unless the parties agree otherwise, the completion of the transaction will take place as soon as practicable (and in any event within five
business days) after all conditions to the completion of the transaction have been satisfied or waived. The transaction will be effective when an order from the Court sanctioning the Scheme of
Arrangement is delivered to the Registrar of Companies. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco
and Rowan currently expect the completion of the transaction to occur in the first half of 2019. However, as the transaction is subject to regulatory clearance, Court approval and
the satisfaction or waiver of other conditions described in the transaction agreement, it is possible that factors outside the control of Ensco and Rowan could result in the transaction being
completed at a later time or not at all. </FONT></P>

Consideration to Be Received in the Transaction  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As a result of the transaction, each Rowan shareholder who is a Scheme Shareholder will be entitled to receive 2.215 Ensco ordinary shares for
each Rowan ordinary share
owned by them that is subject to the Scheme of Arrangement. Each Rowan ordinary share issued and outstanding immediately prior to the Scheme Effective Time will be transferred to Ensco, or
alternatively, to a company falling within Section&nbsp;67(6) of the Finance Act of 1986. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco
will not issue any fractional Ensco ordinary shares in the transaction. Instead, all fractional Ensco ordinary shares will be aggregated and sold in the open market and each holder
of Rowan ordinary shares who would otherwise have been entitled to receive a fraction of an Ensco ordinary share will receive cash from the proceeds of such open market sale in an amount determined
such holder's proportion of aggregate fractional Ensco ordinary shares. </FONT></P>

Corporate Governance  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In connection with the transaction, Ensco is required to take all actions to approve and adopt the Ensco Rowan Corporate Governance Policy and
may not amend, modify or terminate or take any action that would have the effect of causing the combined company to no longer be bound by the Ensco Rowan Corporate Governance Policy, unless required
by applicable law or stock exchange standard. Ensco must also take all action so that, immediately after the Scheme Effective Time, the Ensco Rowan Board will consist of 11 members. Ensco will
designate six members, including Carl Trowell as Executive Chairman of the Ensco Rowan Board, with the remaining five Ensco designees qualifying as "independent directors" under applicable rules of
the NYSE. Rowan will designate five members, including Dr.&nbsp;Thomas Burke as President and Chief Executive Officer, with the four remaining Rowan designees qualifying as "independent directors"
under applicable NYSE rules. If, prior to the Scheme Effective Time, any Ensco director designee or Rowan director designee is unwilling or unable to serve on the Ensco Rowan Board, then Ensco or
Rowan, as applicable, shall select a replacement designee from the members of its board as of the date of the transaction agreement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At
the Scheme Effective Time, Ensco's President and Chief Executive Officer, Dr.&nbsp;Trowell, will become Executive Chairman of the Ensco Rowan Board unless he is unable or unwilling
to serve, in which case a non-executive Chairman will be selected from the Ensco designees with the consent of Rowan, not to be unreasonably withheld, conditioned or delayed. Rowan will identify one
of its designated directors to serve as independent lead director of the Ensco Rowan Board. At the Scheme Effective Time, Rowan President and Chief Executive Officer, Dr.&nbsp;Burke, will become the
President and Chief Executive Officer of the combined company unless he is unable or unwilling to serve. In such case, Dr.&nbsp;Trowell shall be the President and Chief Executive Officer, and a
non-executive Chairman will be selected from the Rowan designees with the consent of Ensco, not to be unreasonably withheld, conditioned or delayed, and Rowan will not appoint a lead independent
director. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Further,
the Ensco Rowan Corporate Governance Policy provides that, for two years following the Scheme Effective Time, the Nominating and Governance Committee of the Ensco Rowan Board
will consist of two of the Ensco designees and two of the Rowan designees. Each other committee of the Ensco Rowan Board shall consist of at least one Ensco designee and at least one Rowan designee,
and the Chairmen of such committees shall be divided as evenly as possible between Ensco and Rowan.
Ensco's Senior Vice President and Chief Financial Officer, Jon Baksht, will serve as Senior Vice President and Chief Financial Officer of the combined company, Ensco's Executive Vice President and
Chief Operating Officer, Patrick Carey Lowe, will serve as Executive Vice President and Chief Operating Officer of the combined company and Ensco's Senior Vice President, General Counsel and
Secretary, Michael T. McGuinty, will serve as Senior Vice President, General Counsel and Secretary of the combined company. The remaining executive management team for the combined company will
comprise executives from both Ensco and Rowan. If, prior to the Scheme Effective Time, any such management team member is unable or unwilling to serve, then a substitute individual will be appointed
by Ensco or Rowan, as applicable, with the consent of the other party, not to be unreasonably withheld, conditioned or delayed. </FONT></P>

Employee Matters  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The transaction agreements provides that Ensco and Rowan will cooperate in good faith to establish a comprehensive employee benefits program for
Rowan employees and Ensco employees as a collective group subject to collective bargaining agreements that are in effect as of the date of the transaction agreement. The transaction agreement further
provides that Ensco and Rowan intend that such post-closing benefits program will equitably treat similarly situated Rowan employees and Ensco employees. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With
respect to any employee benefit plans established as part of the post-closing benefits program, Ensco will (i)&nbsp;recognize all service of Rowan employees and Ensco employees
with Rowan, Ensco or any of their respective subsidiaries or predecessor entities, as the case may be, for purposes of determining eligibility to participate, vesting, accruals, and entitlement to
benefits where length of service is relevant (other than benefit accruals under a defined benefit pension plan) to the extent such service is
recognized under the corresponding benefit plan of Rowan or Ensco (as applicable), (ii)&nbsp;use commercially reasonable efforts to seek to waive any pre-existing condition limitations, eligibility
waiting periods and evidence of insurability requirements and (iii)&nbsp;use commercially reasonable efforts to provide credit for any co-payments and deductibles incurred prior to the Scheme
Effective Time in the plan year in which the Scheme Effective Time occurs for purposes of satisfying any applicable deductible, out-of-pocket or similar requirements under any such employee benefit
plans established under the post-closing benefits program that may apply as of or following the Scheme Effective Time. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Effective
as of the day prior to the closing date of the transaction but contingent upon the closing of the transaction, Rowan will cause to be approved board resolutions terminating the
Rowan Companies,&nbsp;Inc. Savings and Investment Plan (the "Rowan 401(k) Plan") unless Ensco provides written notice to Rowan that the Rowan 401(k) Plan will not be terminated. Unless Ensco
provides such written notice to Rowan, Rowan will provide Ensco copies of such board resolutions. Effective as of, or as soon as administratively practicable following, the closing of the transaction,
each Rowan employee will be eligible to participate in a tax-qualified defined contribution plan established or designated by Ensco (the "Ensco 401(k) Plan"), subject to the terms and conditions of
the Ensco 401(k) Plan. As soon as practicable after the closing of the transaction and to the extent not prohibited under applicable law, Ensco will take all action necessary to provide that each
Rowan employee may elect to rollover his or her full account balance (including cash, notes (in the case of loans) or a combination thereof) in the Rowan 401(k) Plan to the Ensco 401(k) Plan. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
of the Scheme Effective Time, Ensco will automatically assume the change in control agreements entered into between certain employees and Rowan. Except for any such assumed change in
control agreements, the Burke Employment Agreement, any grants made under the Rowan Retention Program through the closing of the transaction, and the Rowan Protection Plan, Rowan will terminate all of
its current severance plans, programs and policies on or prior to the closing date of the transaction. Effective for any employee terminations that occur from the closing date of the transaction
through the twelve-month anniversary of the closing date of the transaction, Ensco will provide to each onshore Rowan employee that is employed as of the closing date of the transaction and who is not
otherwise subject to a change in control agreement, with severance benefits that are no less favorable in the aggregate than those described in the Rowan Retention Program (as and to the extent then
applicable to any such individual) and the Rowan Protection Plan. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On October&nbsp;7, 2018, Ensco and Rowan entered into a definitive transaction agreement under which Rowan will combine with Ensco in an
all-stock transaction. Pursuant to the terms of the transaction agreement, at the Scheme Effective Time, Rowan shareholders who are Scheme Shareholders will receive 2.215 Ensco ordinary shares for
each Rowan ordinary share that is subject to the Scheme of Arrangement. The transaction will be accounted for using the acquisition method of accounting with Ensco identified as the acquirer in
accordance with GAAP. Under the acquisition method of accounting, Ensco will record all assets acquired and liabilities assumed at their respective acquisition-date fair values at the Scheme Effective
Time. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
following unaudited pro forma condensed combined financial statements and the related notes give effect to the proposed transaction between Ensco and Rowan and includes the effects
of Ensco's acquisition of Atwood, which closed on October&nbsp;6, 2017. Ensco separately filed an unaudited pro forma
condensed combined statement of operations giving effect to the Atwood acquisition as Exhibit&nbsp;99.2 to a Current Report on Form&nbsp;8-K filed on October&nbsp;23, 2018 (the "Atwood
Form&nbsp;8-K") and such information is incorporated by reference in this joint proxy statement. Accordingly, we have elected to replace the historical Ensco statement of operations in the unaudited
pro forma combined statement of operations presented herein for the year ended December&nbsp;31, 2017 with the unaudited pro forma condensed consolidated statement of operations reflecting the pro
forma effects of the Atwood acquisition, as reflected in Exhibit&nbsp;99.2 to the Atwood Form&nbsp;8-K. See additional information in </FONT><FONT SIZE=2><I>Note&nbsp;1&#151;Basis of

<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The unaudited pro forma condensed combined financial statements were prepared in accordance with Article&nbsp;11 of SEC Regulation&nbsp;S-X using the acquisition method of accounting
in accordance with GAAP and are based on the historical consolidated financial statements of Ensco and Rowan, after giving effect to the transaction. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
unaudited pro forma condensed combined balance sheet combines the unaudited historical condensed consolidated balance sheets of Ensco and Rowan as of June&nbsp;30, 2018, giving
effect to the transaction as if it had occurred on June&nbsp;30, 2018. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
unaudited pro forma condensed combined statements of operations for the fiscal year ended December&nbsp;31, 2017 and the six months ended June&nbsp;30, 2018 assume the
transaction took place on January&nbsp;1, 2017, the beginning of Ensco's most recently completed fiscal year. The unaudited pro forma condensed combined statement of operations for the fiscal year
ended December&nbsp;31, 2017 combines the unaudited consolidated statement of operations of Ensco and Rowan, including the effects of Ensco's acquisition of Atwood, for the fiscal year ended
December&nbsp;31, 2017. The unaudited pro forma condensed combined statement of operations for the six months ended June&nbsp;30, 2018 combines the unaudited consolidated statement of operations
of Ensco and Rowan, for the six months ended June&nbsp;30, 2018. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
unaudited pro forma condensed combined financial statements are provided for illustrative purposes only and are not intended to represent the consolidated results of operations or
financial
position of the combined company that would have been recorded had the transaction been completed as of the dates indicated and should not be taken as representative of future results of operations or
financial position of the combined company. The unaudited pro forma condensed combined financial statements do not reflect the impacts of any potential operational efficiencies, cost savings or
economies of scale that may be achieved with respect to the combined operations of Ensco and Rowan. Additionally, the pro forma statements of operations do not include non-recurring charges or credits
and the related tax effects that result directly from the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
unaudited pro forma condensed combined financial statements reflect the estimated transaction consideration, which does not represent what the actual transaction consideration
transferred will be as of the closing of the transaction. In accordance with GAAP, the fair value of equity securities issued as the consideration transferred will be measured on the closing date of
the transaction at the then-current market price. Under the terms of the transaction agreement, Rowan stockholders will receive 2.215 Ensco ordinary shares for each Rowan ordinary share for a total
value of $17.96 per Rowan ordinary share based on the closing share price of $8.11 per Ensco ordinary share on October&nbsp;22, 2018. The estimated consideration of $2.3&nbsp;billion is comprised
of 127.8&nbsp;million Rowan ordinary shares, inclusive of 0.8&nbsp;million unvested restricted stock that vest upon change of control, converted to 283.1&nbsp;million Ensco ordinary shares using
the exchange ratio of 2.215 and $12.8&nbsp;million for the estimated fair value of replacement employee equity awards. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
GAAP, merger-related transaction costs (i.e.,&nbsp;advisory, legal, valuation and other professional fees) are not included as a component of consideration transferred but are
accounted for as expenses in the periods in which the costs are incurred. Ensco estimates that advisory, legal, valuation and other professional fees and expenses will be $20&nbsp;million. Costs
incurred by Rowan related to the transaction are estimated to total $24&nbsp;million. Following the completion of the transaction, we expect to incur additional charges and expenses relating to
restructuring and integrating the operations of Ensco and Rowan. </FONT></P>

Note&nbsp;1&#151;Basis of Presentation (Continued) </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
unaudited pro forma condensed combined financial statements illustrate the assets and liabilities of Rowan recorded at their preliminary estimated fair values at the assumed closing
date of the transaction. The preliminary fair value estimates are subject to change based on the final valuations that will be determined as of the closing date of the transaction. Actual results will
differ from this unaudited pro forma condensed combined financial information once we have determined the final transaction consideration and completed the valuation analysis and computations
necessary to finalize the required purchase price allocation. Accordingly, the final allocation of transaction consideration and its effect on results of operations may differ materially from the
preliminary allocation and unaudited pro forma combined amounts included herein. Many of these fair value measurements can be highly subjective, and it is possible that other professionals, applying
reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
unaudited pro forma condensed combined financial statements do not constitute Ensco's statutory accounts required by the Companies Act 2006, which for the year ended
December&nbsp;31, 2017 were prepared in accordance with Financial Reporting Standard&nbsp;102, the Financial Reporting Standard applicable in the UK and Republic of Ireland, and were delivered to
the Registrar of Companies in the United Kingdom. The UK statutory accounts included an unqualified auditor's report, which did not contain any reference to matters to which the auditors drew
attention by way of emphasis without qualifying the report and did not contain a statement under Section&nbsp;498(2) or 498(3) of the Companies Act 2006. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
unaudited pro forma condensed combined financial statements should be read in conjunction with (i)&nbsp;the historical consolidated financial statements and accompanying notes
contained in the Annual Reports on Form&nbsp;10-K and Quarterly Reports on Form&nbsp;10-Q of Ensco and Rowan (in the case of Rowan's Annual Report on Form&nbsp;10-K, as recast in part by Rowan's
Current Reports on Form&nbsp;8-K filed on May&nbsp;9, 2018, with respect to Part&nbsp;II, Item&nbsp;6 and Part&nbsp;II, Item&nbsp;7, and August&nbsp;24, 2018, with respect to
Part&nbsp;II, Item&nbsp;8) and (ii)&nbsp;the unaudited pro forma condensed consolidated statement of operations for the year ended December&nbsp;31, 2017 related to Ensco's completed
acquisition of Atwood, which was filed with the SEC as Exhibit&nbsp;99.2 to the Atwood Form&nbsp;8-K. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under the terms of the transaction agreement, Rowan shareholders will receive 2.215 Ensco ordinary shares for each Rowan ordinary share for a total value of $17.96 per Rowan ordinary
share based on the closing share price $8.11 per Ensco ordinary share on October&nbsp;22, 2018. The estimated consideration of $2.3&nbsp;billion is comprised of 127.8&nbsp;million Rowan ordinary
shares, inclusive of 0.8&nbsp;million unvested restricted stock that vest upon change of control, converted to 283.1&nbsp;million Ensco ordinary shares using the exchange ratio of 2.215 and
$12.8&nbsp;million for the estimated fair value of replacement employee equity awards. The value of the consideration transferred will fluctuate until closing based upon changes in Ensco's share
price and the number of Rowan's ordinary shares and equity awards outstanding. </FONT></P>

Note&nbsp;4&#151;Pro Forma Adjustments (Continued) </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
pro forma adjustment to record the estimated fair value of Rowan's contracts with customers represents the intangible assets recognized for firm contracts that have favorable
contract terms as compared to current market day rates for comparable assets. Contracts that are expected to expire within 12&nbsp;months of the pro forma balance sheet date are classified as
current. The various factors considered in the pro forma adjustment are (1)&nbsp;the contracted day rate for each contract, (2)&nbsp;the remaining term of each contract, (3)&nbsp;the rig class
and (4)&nbsp;the market conditions for each respective rig class at the pro forma balance sheet date. The intangible assets are computed based on the present value of the difference in cash inflows
over the remaining contract term as compared to a hypothetical contract with the same remaining term at an estimated current market day rate using a risk-adjusted discount rate and an estimated
effective income tax rate. The computed amount is subject to change based on changes in contract positions and market conditions until the closing date of the transaction. This balance will be
amortized to operating revenues over the respective remaining contract terms on a straight-line basis. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
pro forma adjustment to record the estimated fair value of inventory arises from a difference in Ensco's and Rowan's accounting policy. Inventory consists of consumable parts and
supplies maintained
on drilling rigs and shore-based warehouse locations for use in operations and generally is comprised of items of low per unit cost and high reorder frequency. The pro forma adjustment to record the
estimated fair value of inventory reflects Ensco's estimate of the fair value of consumable parts and supplies maintained on Rowan's drilling rigs and shore-based locations for use in their
operations. Ensco recognizes inventory for consumable parts and supplies when purchased and subsequently expenses the inventory when consumed. Rowan recognizes expense for consumable parts and
supplies as a period cost when received for use and, therefore, Rowan's historical financial statements do not include an inventory balance. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
pro forma adjustment for the elimination of Rowan's historical deferred contract drilling expenses primarily relates to deferred mobilization costs. Costs incurred for mobilization
of equipment and personnel prior to the commencement of drilling services are deferred and subsequently amortized by Rowan over the term of the related drilling contract. These deferred costs have no
future economic benefit to Ensco and are eliminated from the pro forma financial statements.  </FONT></P>

obligations of Ensco and are eliminated from the pro forma financial statements. The pro forma adjustment to eliminate deferred rent relates to rent expense recognized on a straight-line basis. The
deferred rent does not represent a future obligation to Ensco and is eliminated from the pro forma financial statements.  </FONT></P>

 <P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
pro forma adjustment to record the estimated fair value of Rowan's contracts with customers represents the intangible liabilities recognized for firm contracts that have unfavorable
contract terms as compared to current market day rates for comparable assets. Contracts that are expected to expire within 12&nbsp;months of the pro forma balance sheet date are classified as
current. The various factors considered in the pro forma adjustment are (1)&nbsp;the contracted day rate for each contract, (2)&nbsp;the remaining term of each contract, (3)&nbsp;the rig class
and (4)&nbsp;the market conditions for each respective rig class at the pro forma balance sheet date. The intangible liabilities are computed based on the present value of the difference in cash
inflows over the remaining contract term as compared to a hypothetical contract with the same remaining term at an estimated current market day rate using a risk-adjusted discount rate and an
estimated effective income tax rate. The computed amount is subject to change based on changes in contract positions and market conditions until the closing date of the transaction. This balance will
be amortized to operating revenues over the respective remaining contract terms on a straight-line basis. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
pro forma adjustment for deferred income tax liabilities represents the estimated incremental deferred income taxes, which reflects the tax effect of the difference between the
preliminary estimated
fair value of Rowan's assets, other than goodwill, and liabilities recorded under the acquisition method of accounting and the carryover tax basis of those assets and liabilities. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
pro forma adjustment to eliminate deferred rent relates to rent expense recognized on a straight-line basis. The deferred rent does not represent a future obligation to Ensco and is
eliminated from the pro forma financial statements.  </FONT></P>

discussion is based on and subject to the Internal Revenue Code, the U.S. Treasury Regulations promulgated thereunder, administrative guidance and court decisions as of the date hereof, all of which
are subject to change, possibly with retroactive effect, and to differing interpretations. The discussion assumes that the holders of Rowan ordinary shares hold those shares, and will hold their Ensco
ordinary shares, as "capital assets" within the meaning of Section&nbsp;1221 of the Internal Revenue Code (generally, property held for investment). The discussion does not constitute tax advice and
does not address state, local or non-U.S. tax consequences of the transaction (or any U.S. federal taxation other than income taxation); nor does it address all aspects of U.S. federal income taxation
that may be relevant to particular Rowan shareholders or Ensco shareholders in light of their personal circumstances, including any tax consequences arising under the Medicare contribution tax on net
investment income, or to such
shareholders subject to special treatment under the Internal Revenue Code, such as:</FONT></P>

Tax Consequences of the Transaction to Rowan and Ensco  </B></FONT></P>

Code for U.S. federal income tax purposes, and the remainder of the disclosure assumes it will so qualify. However, Ensco and Rowan have not sought and will not seek any ruling from the IRS regarding
any matters relating to the transaction, and as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a contrary position, in which case the consequences
of the transaction could be materially different from those described below. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Neither
Rowan nor Ensco is expected to be subject to U.S. federal income tax as a result of the transaction. In conjunction with the transaction, Rowan, Ensco and their respective
affiliates will engage in certain additional intercompany transactions. The discussion herein does not address the U.S. federal income tax treatment of such transactions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco
and Rowan both believe they are currently treated as foreign corporations for U.S. federal income tax purposes. Ensco and Rowan further expect that, following the transaction, they
will continue to be treated as foreign corporations for U.S. federal income tax purposes, and the remainder of this disclosure assumes such treatment. It is possible, however, that the IRS could
disagree with this treatment. Should the IRS conclude that Ensco or Rowan is properly treated as a U.S. "domestic" corporation for U.S. federal income tax purposes (and such conclusion is not
overturned), this could materially alter the anticipated tax consequences of the transaction and future ownership of Ensco ordinary shares. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>holders
that exchange Rowan ordinary shares for Ensco ordinary shares and cash in lieu of fractional shares in the transaction will be as follows: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Upon
exchanging Rowan ordinary shares for Ensco ordinary shares, the Rowan shareholder will not recognize gain or loss, except with respect to cash received in lieu of fractional Ensco
ordinary shares (as discussed below). The aggregate tax basis of the Ensco ordinary shares received in the transaction (including any fractional shares deemed received and exchanged for cash, as
discussed below) will equal the Rowan shareholder's aggregate adjusted tax basis in the Rowan ordinary shares surrendered in the transaction. The Rowan shareholder's holding period for the Ensco
ordinary shares received in the transaction (including any fractional share deemed received and exchanged for cash, as discussed below) will include the Rowan shareholder's holding period for the
Rowan ordinary shares surrendered in the transaction. If a Rowan shareholder acquired Rowan ordinary shares at different times or at different prices, the basis of each Rowan ordinary share shall be
allocated to the Ensco ordinary shares received in the exchange in proportion to the fair market value of the Ensco ordinary shares received. The holding period of Ensco ordinary shares received by a
Rowan shareholder in the transaction will include the holding period of the Rowan ordinary shares exchanged for such Ensco ordinary shares. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
a Rowan shareholder receives cash in lieu of a fractional Ensco ordinary share, such shareholder will be treated as having received such fractional Ensco ordinary share pursuant to
the transaction and then as having sold such fractional Ensco ordinary share for cash. As a result, the Rowan shareholder generally will recognize capital gain or loss equal to the difference between
the amount of cash received for such fractional share and the shareholder's basis in its fractional Ensco ordinary share. Such capital gain or loss generally will be long-term capital gain or loss if,
as of the effective date of the transaction, the Rowan shareholder's holding period for such fractional share (as described above) exceeds one year. Long-term capital gains of individuals are
generally eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
Section&nbsp;367(a) of the Internal Revenue Code and the Treasury Regulations thereunder, special rules may require a U.S. holder who receives Ensco ordinary shares in the
transaction and becomes a
five-percent shareholder (within the meaning of applicable Treasury Regulations) of Ensco immediately after the transaction to recognize gain (but not loss) as a result of such U.S. holder's exchange
of Rowan ordinary shares pursuant to the transaction. Any U.S. holder of Rowan ordinary shares that will be a five-percent shareholder of Ensco after the transaction is urged to consult his, her or
its own tax advisor with respect to the U.S. federal income tax consequences of the transaction. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Notwithstanding
the foregoing, if Ensco is not a PFIC in the taxable year of the transaction, but Rowan has been a PFIC at any time since a U.S. holder acquired its Rowan ordinary
shares, pursuant to proposed Treasury Regulations, a direct or indirect U.S. holder of Rowan ordinary shares may have to recognize gain but not loss in connection with the receipt of Ensco ordinary
shares for Rowan ordinary shares in the transaction. As described below in the section "Passive Foreign Investment Company Considerations," Ensco does not believe that it will be classified as a PFIC
for its current taxable year. Rowan believes that it has not been a PFIC and will not be classified as a PFIC for its current taxable year. However, the determination of PFIC status is factual in
nature, depends on the application of complex U.S. federal income tax rules that are subject to differing interpretations, and generally cannot be determined until the close of the taxable year in
question. U.S. holders should consult their own tax advisors regarding the classification of Rowan as a PFIC, and the effect of the PFIC rules on such holder. </FONT></P>

Taxation of Distributions to U.S. Holders  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Distributions with respect to Ensco ordinary shares will be treated as a dividend to U.S. holders to the extent that they are paid out of
Ensco's current or accumulated earnings and profits, as determined under U.S. federal income tax principles. The dividend income will be treated as foreign source, passive income for foreign tax
credit limitation purposes. Subject to the following discussion of special rules applicable to PFICs, the gross amount of the dividends paid by Ensco to U.S. holders may be eligible for taxation at
lower rates. The maximum U.S. federal income tax rate imposed on dividends received by non-corporate U.S. holders from certain "qualified foreign corporations" is currently 20%, provided that certain
holding period requirements are satisfied and certain other requirements are met. Dividends paid with respect to stock of a foreign corporation which is readily tradable on an established securities
market in the United States will be treated as having been received from a "qualified foreign corporation." The U.S. Treasury and the IRS have determined that common stock is considered readily
tradable on an established securities market if it is listed on an established securities market in the United States, such as the NYSE. Accordingly, dividends received by non-corporate U.S. holders
should be eligible for favorable treatment as dividends received with respect to stock of a "qualified foreign corporation." Dividends paid by Ensco will not qualify for the dividends received
deduction otherwise available to corporate stockholders. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To
the extent that the amount of any distribution exceeds Ensco's current and accumulated earnings and profits for a taxable year, the excess will first be treated as a tax-free return
of capital, causing a reduction in the U.S. holder's adjusted tax basis in U.S. holder's Ensco ordinary shares. The balance of the excess, if any, will be treated as gain from the sale of such U.S.
holder's Ensco ordinary shares, as described below under "&#151;Sale, Exchange or Other Taxable Disposition by U.S. Holders." </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It
is possible that Ensco is, or at some future time will be, at least 50% owned by U.S. persons. Dividends paid by a foreign corporation that is at least 50% owned by U.S. persons may
be treated as U.S. source income (rather than foreign source income) for foreign tax credit purposes to the extent the foreign corporation has more than an insignificant amount of U.S. source income.
The effect of this rule may be to treat a portion of any dividends paid by Ensco as U.S. source income. Treatment of the dividends as U.S. source income in whole or in part may limit a U.S. holder's
ability to claim a foreign tax credit with respect to foreign taxes payable or deemed payable in respect of the dividends or other items of foreign source, passive income for U.S. federal foreign tax
credit limitation purposes. The Internal Revenue Code permits a U.S. holder entitled to benefits under the UK-U.S. Income Tax Treaty to elect to treat any company dividends as foreign source income
for foreign tax credit purposes if the
dividend income is separated from other income items for purposes of calculating the U.S. holder's foreign tax credit. U.S. holders should consult their own tax advisors about the desirability and
method of making such an election. The calculation of foreign tax credits involves the application of complex rules that depend on a U.S. Holder's particular circumstances. U.S. Holders are strongly
urged to consult their own tax advisors regarding the availability of foreign tax credits. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A foreign corporation is a PFIC if, after the application of certain "look-through" rules, (i)&nbsp;at least 75% of its gross income is
"passive income" as that term is defined in the relevant provisions of the Internal Revenue Code and IRS rules, or (ii)&nbsp;at least 50% of the average value of its assets produce "passive income"
or are held for the production of "passive income." Ensco is not expected to be a PFIC for the current tax year, and is not expected to become a PFIC in the future.
However, this conclusion is a factual determination made annually and is subject to change. There can be no assurance that the IRS will not successfully challenge this position or that Ensco will not
be or become a PFIC at some future time. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
a U.S. holder is treated as owning stock in a PFIC, the U.S. holder will be subject to special rules intended to reduce or eliminate the benefit of the deferral of U.S. federal income
tax that results from investing in a foreign corporation that does not distribute all of its earnings on a current basis. These rules may adversely affect the tax treatment to a U.S. holder of
dividends paid by Ensco and of sales, exchanges and other dispositions of Ensco ordinary shares, and may result in other U.S. federal income tax consequences. U.S. holders should consult their own tax
advisors about the determination of Ensco's PFIC status and the U.S. federal income tax consequences of holding Ensco ordinary shares if Ensco is considered a PFIC in any taxable year. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following discussion is a general summary of the material UK tax considerations for non-UK resident and non-UK domiciled shareholders
("non-UK holders") relating to (i)&nbsp;the transaction and (ii)&nbsp;the holding of Ensco ordinary shares. The discussion is based on current UK tax law as applied in England and Wales and HMRC
practice (which may not be binding on HMRC) as at the date of this summary, both of which are subject to change, possibly with retrospective effect. The discussion is intended as a general guide and
applies only to non-UK holders, who hold their shares as an investment and who are the absolute beneficial owners thereof. The discussion does not address all possible tax consequences relating to the
transaction or of an investment in Ensco ordinary shares. Certain categories of shareholders, including those carrying on certain financial activities, those subject to specific tax regimes or
benefitting from certain reliefs or exemptions, those connected with Rowan or Ensco and those for whom their shares are employment-related securities may be subject to special rules and this summary
does not apply to such shareholders and any general statements made in this disclosure do not take them into account. This summary does not address any inheritance tax considerations. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
summary is for general information only and is not intended to be, nor should it be considered to be, legal or tax advice to any particular investor. It does not address all of the
tax considerations that may be relevant to specific investors in light of their particular circumstances or to investors subject to special treatment under UK tax law. In particular: </FONT></P>

Taxation of Dividends  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The UK does not currently impose withholding tax on dividends paid by Ensco to its shareholders, whether the shareholders are resident in the UK
for tax purposes or resident in any other jurisdiction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;An individual non-UK holder that does not conduct any trade, profession or vocation in the UK to which the shares are attributable will not be
liable to UK capital gains tax on capital gains realized on the exchange of his or her Rowan ordinary shares for Ensco ordinary shares or the later disposal of his or her Ensco ordinary shares. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A

General  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;An agreement to transfer UK shares will normally give rise to a charge to SDRT at the rate of 0.5% of the amount or value of the consideration
payable for the transfer. SDRT is, in general, payable by the purchaser. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Transfers
of UK shares will generally be subject to stamp duty at the rate of 0.5% of the consideration given for the transfer (rounded up to the next &pound;5). The purchaser
normally pays the stamp duty. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
a duly stamped transfer completing an agreement to transfer is produced within six years of the date on which the agreement is made (or, if the agreement is conditional, the date on
which the agreement becomes unconditional), any SDRT already paid is generally repayable, normally with interest, and any SDRT charge yet to be paid is cancelled. </FONT></P>

Depositary Receipt Systems and Clearance Services  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Where UK shares are transferred (i)&nbsp;to, or to a nominee or an agent for, a person whose business is or includes the provision of
clearance services or (ii)&nbsp;to, or to a nominee or an agent for, a person whose business is or includes issuing depositary receipts, stamp duty or SDRT will generally be payable at the higher
rate of 1.5% of the amount or value of the consideration given or, in certain circumstances, the value of the shares. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There
is an exception from the 1.5% charge on the transfer to, or to a nominee or agent for, a clearance service where the clearance service has made and maintained an election under
section&nbsp;97A(1) of the Finance Act 1986, which has been approved by HMRC. In these circumstances, SDRT at the rate of 0.5% of the amount or value of the consideration payable for the transfer
will arise on any transfer of UK shares into such an account and on subsequent agreements to transfer such shares within such account. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Any
liability for stamp duty or SDRT in respect of a transfer into a clearance service or depositary receipt system, or in respect of a transfer within such a service, which does arise
will strictly be accountable by the clearance service or depositary receipt system operator or their nominee, as the case may be, but will, in practice, be payable by the issuer or participants in the
clearance service or depositary receipt system. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pursuant
to arrangements that Ensco entered into with DTC, the Ensco ordinary shares are eligible to be held in book-entry form through the facilities of DTC. Transfers of Ensco ordinary
shares held in book-entry form through DTC should not attract a charge to stamp duty or SDRT in the UK. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following information is a summary of the material terms of the Ensco ordinary shares (as defined below), as specified in the Ensco Articles
of Association. This summary is not complete and is subject to the complete text of the Ensco Articles of Association. You are encouraged to carefully read the Ensco Articles of Association. </FONT></P>

Share Capital  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of October&nbsp;5, 2018, Ensco had (i)&nbsp;127,063,751 Ensco ordinary shares, excluding Ensco ordinary shares held in treasury, and
(ii)&nbsp;50,000 Ensco Class&nbsp;B ordinary shares, nominal value &pound;1.00 per share (the "Ensco Class&nbsp;B ordinary shares"), in issue and held by one of Ensco's subsidiaries. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;All
of the issued Ensco ordinary shares are fully paid and are not subject to any further calls by Ensco. There are no conversion rights, redemption provisions or sinking fund provisions
relating to any Ensco ordinary shares; however, subject to the Companies Act 2006, Ensco may purchase or contract to purchase any of its ordinary shares off-market. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
English law, persons who are neither residents nor nationals of the United Kingdom may freely hold, vote and transfer Ensco's shares in the same manner and under the same terms as
United Kingdom residents or nationals. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Ensco ordinary shares and the Ensco Class&nbsp;B ordinary shares have the same rights and privileges in all respects. While the Ensco Class&nbsp;B ordinary shares remain in
issue, such shares have no voting rights or rights to dividends or distributions, to the extent that Ensco or any of Ensco's subsidiaries hold such shares. </FONT></P>

Dividends  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subject to the Companies Act 2006, the Ensco Board may declare a dividend to be paid to Ensco's shareholders according to their respective
rights and interests in Ensco, and may fix the time for payment of such dividend. The Ensco Board may from time to time declare and pay (on any class of shares of any amounts) such dividends as appear
to them to be justified by Ensco's profits that are available for distribution. When evaluating dividend payment timing and amounts, the Ensco Board considers several factors, including Ensco's
profitability, liquidity, financial condition, market outlook, reinvestment opportunities, capital requirements and other factors and restrictions the Ensco Board deems relevant. There can be no
assurance that Ensco will pay a dividend in the future. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There
are no fixed dates on which entitlement to dividends arise on any of Ensco's ordinary shares. The Ensco Board may direct the payment of all or any part of a dividend to be
satisfied by distributing specific assets, in particular paid up shares or debentures of any other company. The Ensco Articles of
Association permit a scrip dividend scheme under which shareholders may be given the opportunity to elect to receive fully paid Ensco ordinary shares instead of cash, with respect to all or part of
future dividends. Any ordinary shares Ensco or any of Ensco's subsidiaries hold will not be entitled to any dividends or distributions, including any scrip dividends, bonus shares or dividends or
distributions of property or debentures of any other company. Further, the trustees of an employee benefit trust established in connection with Ensco's equity incentive plans are not entitled to any
dividends or distributions, including any scrip dividends, bonus shares or dividends or distributions of property or debentures of any other company. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
a shareholder owes any money to Ensco relating in any way to any class of Ensco ordinary shares, the Ensco Board may deduct any of this money from any dividend on any shares held by
the shareholder, or from other money payable by Ensco in respect of the shares. Money deducted in this way may be used to pay the amount owed to Ensco. </FONT></P>

Voting Rights  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At a general meeting of Ensco shareholders, any resolution put to a vote must be decided on a poll rather than by a show of hands. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Each
Ensco shareholder (other than any of its subsidiaries who hold Ensco ordinary shares) who (being an individual) is present in person or (being a corporation) is present by a duly
authorized corporate representative at Ensco's general meeting will have one vote for every share held, and every person present who has been appointed as a proxy has one vote for every share in
respect of which he or she is the proxy, except that any proxy who has been appointed by DTC or its proxies have such number of votes as equals the number of shares in relation to which such proxy has
been appointed, subject to any rights or restrictions as to voting attached to any class of shares in accordance with the Ensco Articles of Association or by agreement and subject to the
disenfranchisement (i)&nbsp;in the event of non-payment of any call or other sum due and payable in respect of any shares not fully paid, (ii)&nbsp;in the event of any non-compliance with any
statutory notice requiring disclosure of an interest in shares and (iii)&nbsp;with
respect to any shares held by the trustees of an employee benefit trust established in connection with Ensco's equity incentive plans in which a beneficial interest has not yet vested in a beneficiary
of such trust. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
the case of joint holders, the vote of the person whose name stands first in the register of shareholders and who tenders a vote, whether in person or by proxy, is accepted to the
exclusion of any votes tendered by any other joint holders. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
necessary quorum for a general meeting is the shareholders who together represent at least the majority of the voting rights of all the shareholders entitled to vote present in
person or by proxy (that is, any shares whose voting rights have been disenfranchised (whether pursuant to the Companies Act 2006 and/or under the Ensco Articles of Association) are disregarded for
the purposes of determining a quorum). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;An
annual general meeting of Ensco shareholders must be called by not less than 21 clear days' notice and no more than 60&nbsp;days' notice. For all other general meetings except
general meetings properly requisitioned by shareholders, such meetings may be called by not less than 14 clear days' notice and no more than 60&nbsp;days' notice. The notice of meeting also must
specify a time (which may not be more than 60&nbsp;days nor less than 10&nbsp;days before the date of the meeting) by which a person must be entered on the register in order to have the right to
attend or vote at the meeting. The number of shares then registered in their respective names will determine the number of votes a person is entitled to cast at that meeting. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ensco
must receive an appointment of proxy (whether in hard copy form or electronic form) before the time for holding the meeting or adjourned meeting at which the person named in the
appointment of proxy proposes to vote; in the case of a poll taken more than 48&nbsp;hours after the meeting at which the relevant vote was to be taken, an appointment of proxy must be received
after such meeting and not less than 24&nbsp;hours (or such shorter time as the Ensco Board may determine) before the time appointed for taking the poll; or in the case of a poll not taken
immediately but taken not more than 48&nbsp;hours after the meeting, the appointment of proxy must be delivered at the meeting at which the poll is to be taken. An appointment of proxy not received
or delivered in accordance with the Ensco Articles of Association is invalid under English law. </FONT></P>

Return of Capital  </B></FONT></P>

or any part of Ensco's assets, whether or not the assets consist of property of one kind or of different kinds. </FONT></P>

liquidator also may, with the same authority, transfer the whole or any part of the assets to trustees upon any trusts for the benefit of the shareholders as the liquidator decides.

Pre-Emptive Rights and New Issues of Shares  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under section&nbsp;549 of the Companies Act 2006, directors are, with certain exceptions, unable to allot securities without being authorized
either by the shareholders in a general meeting or by the Ensco Articles of Association pursuant to section&nbsp;551 of the Companies Act 2006. In addition, under the Companies Act 2006, the
issuance of equity securities that are to be paid for wholly in cash (except shares held under an employees' share scheme) must be offered first to the existing equity shareholders in proportion to
the respective nominal values of their holdings on the same or more favorable terms, unless a special resolution to the contrary has been passed at a general meeting of shareholders or the Articles of
Association otherwise provide an exclusion from this requirement (which exclusion can be for a maximum of five years after which shareholders' approval would be required to renew the exclusion). In
this context, equity securities generally means ordinary shares (being shares other than shares that, with respect to dividends or capital, carry a right to participate only up to a specified amount
in a distribution) and all rights to subscribe for or convert securities into such shares. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;21, 2018, shareholder resolutions were adopted which authorized the directors (generally and unconditionally), for a period up to the conclusion of the next annual general
meeting of shareholders (or, if earlier, at the close of business on August&nbsp;21, 2019), to allot Ensco ordinary shares and to grant rights to subscribe for or convert any security into Ensco
ordinary shares: (i)&nbsp;up to an aggregate nominal amount of $14,561,218, and (ii)&nbsp;up to a nominal amount of $29,122,436 in connection with a rights issue or other similar issue (such
amount to be reduced by the nominal amount of Ensco ordinary shares allotted pursuant to (i)). Additional shareholder resolutions were adopted which authorized the directors to: (i)&nbsp;allot
equity securities for cash free of pre-emption rights up to an aggregate nominal amount of $2,186,369, and (ii)&nbsp;to further allot equity securities for cash free of pre-emption rights up to an
aggregate nominal amount of $2,186,369 for the purposes of financing (or refinancing if the authority is to be used within six months after the relevant transaction) a transaction which the Ensco
Board deems to be an acquisition or other capital investment, such authority to be effective until the
conclusion of Ensco's next annual general meeting of shareholders (or, if earlier, at the close of business on August&nbsp;21, 2019). Ensco may, before the expiration of any authority to allot
shares or disapply pre-emption rights granted pursuant to the shareholder resolutions adopted on May&nbsp;21, 2018, make an offer or agreement that would or might require the Ensco ordinary shares
to be allotted (or rights to be granted) after such expiration, and the directors may allot shares or grant rights in pursuance of such an offer or agreement as if the authority to allot had not
expired. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subject
to the provisions of the Companies Act 2006 and to any rights attached to any existing shares, the Ensco ordinary shares may be issued with, or have attached to them, such rights
or restrictions as Ensco's shareholders may by ordinary resolution determine, or, where the above authorizations are in place, the Ensco Board may determine such rights or restrictions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Companies Act 2006 prohibits an English company from issuing shares for no consideration, including with respect to grants of restricted shares made pursuant to equity incentive
plans. Accordingly, the nominal value of the shares issued upon the lapse of restrictions or the vesting of any restricted share award or any other share-based grant must be paid pursuant to the
Companies Act 2006. </FONT></P>

Disclosure of Interests in Shares  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;793 of the Companies Act 2006 provides Ensco the power to require a person whom Ensco knows has, or whom Ensco has reasonable
cause to believe has, or within the previous three years has had, any ownership interest in any shares (the "default shares") to disclose prescribed particulars of those shares. For this purpose
default shares includes any shares allotted or issued after the date of the Section&nbsp;793 notice in respect of those shares. Failure to provide the information requested within the prescribed
period after the date of sending the notice will result in sanctions being imposed against the holder of the "default shares" as provided within the Companies Act 2006. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under

Liability of Ensco's Directors and Officers  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Ensco Articles of Association provide that English courts have exclusive jurisdiction with respect to any suits brought by shareholders
against Ensco or its directors. English law does not permit a company to exempt any director or certain officers from any liability arising from negligence, default, breach of duty or breach of trust
against the company. However, despite this prohibition, an English company is permitted to purchase and maintain insurance for a director or executive officer of the company against any such
liability. Ensco has entered into deeds of indemnity with each of its current directors and executive officers and purchased insurance on their behalf. In addition, directors and executive officers
may be covered by indemnification agreements and indemnification rights granted under the charter documents of Ensco's subsidiaries. Shareholders can ratify by ordinary resolution a director's or
certain officer's conduct amounting to negligence, default, breach of duty or breach of trust in relation to the company. </FONT></P>

Takeover Code  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Takeover offers and certain other transactions in respect of certain public companies are regulated by the Takeover Code, which is administered
by the Takeover Panel, a body consisting of representatives of the City of London financial and professional institutions that oversees the conduct of takeovers. An English public limited company
potentially will potentially be subject to the Takeover Code if, among other factors, its central place of management and control is within the UK, the Channel Islands or the Isle of Man. The Takeover
Panel generally will look to the residency of a company's directors to determine where it is centrally managed and controlled. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Takeover Panel has previously confirmed that on the basis of Ensco's current directors and management the Takeover Code would not apply to Ensco. It is not expected that the Takeover
Code will apply to the combined entity following consummation of the transaction, whoever, it is possible that if the characteristics of Ensco Rowan's directors or management were to change in the
future the Takeover Panel may take a different position and the Takeover Code may apply to Ensco and Rowan. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The provisions of Ensco's Articles of Association summarized below may have the effect of discouraging, delaying or preventing hostile

Issuance of Additional Shares  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Ensco Board has the authority, without further action of Ensco's shareholders, but subject to its statutory and fiduciary duties, to allot
shares, or to grant rights to subscribe for or to convert or exchange any security into shares, up to: (i)&nbsp;an aggregate nominal amount of $14,561,218, and (ii)&nbsp;up to a nominal amount of
$29,122,436 in connection with a rights issue or other similar issue (such amount to be reduced by the nominal amount of Ensco ordinary shares allotted pursuant to (i)), to allot equity securities for
cash free of pre-emption rights up to an aggregate nominal amount of $2,186,369, and to further allot equity securities for cash free of pre-emption rights up to an aggregate nominal amount of
$2,186,369 for the purposes of financing (or refinancing, if the power is to be used within six months after the relevant transaction) a transaction which the Ensco Board deems to be an acquisition or
other capital investment. Such authority will continue until the conclusion of Ensco's next annual general meeting of shareholders (or, if earlier, the close of business on August&nbsp;21, 2019) and
thereafter it must be renewed. The issuance of further shares on various terms could adversely affect the Ensco shareholders. The potential issuance of further shares may discourage bids for Ensco
ordinary shares at a premium over the market price, may adversely affect the market price of Ensco ordinary shares and may discourage, delay or prevent a change of control. </FONT></P>

Shareholder Rights Plan  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Ensco Board has the necessary corporate authority to exercise any power of the company to establish a shareholders rights plan. Any
shareholders rights plan may be in such form as the Ensco Board may in its absolute discretion decide. Such a plan could make it more difficult for another party to obtain control of Ensco by
threatening to dilute a potential acquirer's ownership interest under certain circumstances. The Ensco Board may adopt a shareholder rights plan at any time. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
anti-takeover and other provisions of the Ensco Articles of Association, as well as the adoption of a shareholder rights plan, could discourage potential acquisition proposals and
could delay or prevent a change of control. These provisions are intended to enhance shareholder value by discouraging certain types of abusive takeover tactics. However, these provisions could have
the effect of discouraging others from making tender offers for Ensco ordinary shares and, as a consequence, also may inhibit fluctuations in the market price of Ensco ordinary shares that could
result from actual or rumored takeover attempts. </FONT></P>

Board of Directors  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At every annual general meeting all Ensco directors must retire from office and each director may offer himself or herself for re-appointment by
the members. Under English law, shareholders have no cumulative voting rights. In addition, Ensco's Articles of Association incorporate provisions that regulate shareholders' ability to nominate
directors for election. Although Ensco's shareholders have the ability to remove a director without cause under English law, the lack of cumulative voting and the limitations on shareholders' powers
to nominate directors will have the effect of making it more difficult not only for any party to obtain control over Ensco by replacing the majority of the Ensco Board but also to force an immediate
change in the composition of the Ensco Board. However, under Ensco's Articles of Association, if Ensco shareholders remove the entire Ensco Board, a shareholder may then convene a general meeting for
the purpose of appointing directors. </FONT></P>

Ensco's principal executive office, in writing and in accordance with SEC Rule&nbsp;14a-8, no later than December&nbsp;10, 2018 for inclusion in the proxy statement related to that meeting. The

addition, apart from the SEC Rule&nbsp;14a-8 process described above, a shareholder whose proposal is not included in the proxy statement related to the 2019 Annual General Meeting
of Shareholders, but who still intends to submit a proposal at that meeting, is required by the Ensco Articles of Association to deliver such proposal, in proper form, in writing, to Ensco's secretary
at Ensco's principal executive offices and to provide certain other information, not earlier than the close of business on the 75th&nbsp;day and not later than the close of business on the

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Any
such proposal must also comply with the other provisions contained in the Ensco Articles of Association relating to shareholder proposals, including provision of the information
specified in the Ensco Articles of Association, such as information concerning the nominee of the proposal, if any, and the shareholder and the beneficial owner, as the case may be. Any proposals that
do not meet the requirements set forth in the Ensco Articles of Association, other than proposals submitted in compliance with SEC Rule&nbsp;14a-8 under the Exchange Act, will be declared out of

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition to the SEC and the Ensco Articles of Association processes described above, under the Companies Act 2006, shareholders representing at least 5% of the total voting rights of
all shareholders who have a right to vote at the 2019 Annual General Meeting of Shareholders can require Ensco to give shareholders notice of a resolution which may be and is intended to be moved at
the Annual General Meeting of Shareholders unless (a)&nbsp;the resolution would, if passed, be ineffective (whether by reason of inconsistency with any enactment or Ensco's constitution or
otherwise); (b)&nbsp;it is defamatory of any person; or (c)&nbsp;it is frivolous or vexatious. Such a request, made by the requisite number of shareholders, must be received by Ensco not later
than six weeks before the Annual General Meeting of Shareholders. For information as to how you can obtain a copy of the Ensco Articles of Association, see "Where You Can Find More Information." </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The SEC allows Ensco and Rowan to incorporate by reference information in this joint proxy statement. This means that Ensco and Rowan can
disclose important information to you by referring you to another document filed separately with the SEC. The information incorporated by reference is considered to be a part of this joint proxy
statement, except for any information that is superseded by information that is included directly in this joint proxy statement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
SEC maintains an internet website that contains reports, proxy statements and other information about issuers, like Ensco and Rowan, who file electronically with the SEC. The address
of the site is www.sec.gov. The reports and other information filed by Ensco with the SEC, including a copy of the Ensco Articles of Association, are also available at Ensco's internet website
(www.enscoplc.com). The reports and other information filed by Rowan with the SEC, including a copy of Rowan's Articles of Association, are also available at Rowan's internet website (www.rowan.com).
We have included the web addresses of the SEC, Ensco, and Rowan as inactive textual references only. Except as specifically incorporated by reference into this joint proxy statement, information on
those websites is not part of this joint proxy statement. </FONT></P>

reasonably designed to ensure that all material information required to be disclosed by Rowan in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to Rowan's management as appropriate to allow

respectively, of Rule&nbsp;13a-15 under the Exchange Act) as required by Rule&nbsp;13a-15 under the Exchange Act. Ensco's disclosure controls and procedures are reasonably designed to ensure that
all material information required to be disclosed by Ensco in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods
specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to Ensco's management as appropriate to allow timely decisions regarding required
disclosure and to make the certifications required pursuant to Sections&nbsp;302 and 906 of the Sarbanes-Oxley Act. Ensco's management has completed an assessment of the effectiveness of Ensco's
internal control over financial reporting in compliance with the requirements of Section&nbsp;404 of the Sarbanes-Oxley Act for the year ended December&nbsp;31, 2017, and such assessment concluded
that such controls were effective. Based on its most recent evaluation of internal controls over financial reporting prior to the date hereof management of Ensco has disclosed to Ensco's auditors and
the audit committee of the Board of Directors of Ensco (i)&nbsp;any significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting that are
reasonably likely to adversely affect in any material respect Ensco's ability to record, process, summarize and report financial information and (ii)&nbsp;any fraud, whether or not material, that
involves management or other employees who have a significant role in Ensco's internal control over financial reporting, and each such deficiency, weakness and fraud so disclosed to auditors, if any,
has been disclosed to Rowan prior to the date hereof. </FONT></P>

understand that Rowan Companies&nbsp;plc (the "Company") and Ensco&nbsp;plc ("Ensco"), propose to enter into a Transaction Agreement, substantially in the form of the draft dated
October&nbsp;5, 2018 (the "Transaction Agreement"), which provides, among other things, for the acquisition of all of the outstanding Class&nbsp;A ordinary shares, nominal value $0.125 per share,
of the Company (the "Company Ordinary Shares") by Ensco pursuant to a scheme of arrangement (the "Scheme") under Part&nbsp;26 of the UK Companies Act 2006 (the "Transaction"). Pursuant to the
Transaction and the Scheme, each outstanding share of the Company Ordinary Shares will be transferred to Ensco or its nominee in exchange for 2.215 shares (the "Exchange Ratio") of Class&nbsp;A
ordinary shares, nominal value $0.10 per share, of Ensco (the "Ensco Ordinary Shares"), subject to adjustment in certain circumstances. The terms and conditions of the Transaction are more fully set
forth in the Transaction Agreement. </FONT></P>

have assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to
us by the Company and Ensco, and formed a substantial basis for this opinion. With respect to the financial projections, including information relating to certain strategic, financial and operational
benefits anticipated from the Transaction, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the respective
managements of the Company and Ensco of the future financial performance of the Company and Ensco. For purposes of our analysis, we have, at the direction of Ensco, relied on financial projections
relating to the Company and Ensco, in each case prepared by the management of Ensco. We have been advised by Ensco and have assumed, with Ensco's consent, that the projections prepared by the
management of Ensco are a reasonable basis upon which to evaluate the business and financial prospects of Ensco and the Company. We express no view as to such projections or the assumptions on which
they were based. We have relied upon, without independent verification, the assessment by the management of Ensco of: (i)&nbsp;the strategic, financial and other benefits expected to result from the
Transaction; (ii)&nbsp;the timing and
risks associated with the integration of the Company and Ensco; and (iii)&nbsp;Ensco's ability to retain key employees of the Company and Ensco, respectively. In addition, we have assumed that the
Transaction will be consummated in accordance with the terms set forth in the Transaction Agreement without any waiver, amendment or delay of any terms or conditions, including, among other things,
that the Transaction will be treated as a tax-free reorganization, pursuant to the Internal Revenue Code of 1986, as amended, and that the definitive Transaction Agreement will not differ in any
material respect from the draft thereof furnished to us. Morgan Stanley has assumed that in connection with the receipt of all the necessary governmental, regulatory or other approvals and consents
required for the proposed Transaction, no delays, limitations, conditions or restrictions will be imposed that would have a material adverse effect on the contemplated benefits expected to be derived
in the proposed Transaction. We are not legal, tax or regulatory advisors. We are financial advisors only and have relied upon, without independent verification, the assessment of Ensco and the
Company and their legal, tax or regulatory advisors with respect to legal, tax or regulatory matters. We express no opinion with respect to the fairness of the amount or nature of the compensation to
any of the Company's officers, directors or employees, or any class of such persons, relative to the consideration to be paid to the holders of Company Ordinary Shares in the Transaction. We have not
made any independent valuation or appraisal of the assets or liabilities of the Company or Ensco, nor have we been furnished with any such valuations or appraisals. Our opinion does not address the
relative merits of the Transaction as compared to any other alternative business transaction, or other alternatives, or whether or not such alternatives could be achieved or are available. Our opinion
is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof may
affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We

and a substantial portion of which is contingent upon the closing of the Transaction. In the two years prior to the date hereof, we have provided financial advisory and financing services for
Ensco and financing services for the Company and have received fees in connection with such services. As of the date hereof, Morgan Stanley is a lender under Ensco's revolving credit facility. Morgan
Stanley may also seek to provide financial advisory and financing services to Ensco and the Company and their respective affiliates in the future and would expect to receive fees for the rendering of

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
opinion has been approved by a committee of Morgan Stanley investment banking and other professionals in accordance with our customary practice. This opinion is for the information

summary of this opinion that is acceptable to Morgan Stanley, may be disclosed in any filing Ensco is required to make with the U.S. Securities and Exchange Commission in connection with the
Transaction if such inclusion is required by applicable law. In addition, this opinion does not in any manner address the prices at which Ensco Ordinary Shares will trade following consummation of the
Transaction or at any time and Morgan Stanley expresses no opinion or recommendation as to how the shareholders of Ensco and the Company should vote at the shareholders' meetings to be held in
connection with the Transaction. </FONT></P>

have requested our opinion as to the fairness from a financial point of view to the holders (other than Ensco&nbsp;plc ("Ensco") and its affiliates) of the outstanding
Class&nbsp;A ordinary shares, par value $0.125 per share (the "Company Ordinary Shares"), of Rowan Companies&nbsp;plc (the "Company") of the Exchange Ratio (as defined below) to be paid to such
holders pursuant to the Transaction Agreement, dated as of October&nbsp;7, 2018, by and between Ensco and the Company (the "Agreement"). The Agreement (i)&nbsp;provides that pursuant to the Scheme
of Arrangement (as defined in the Agreement), each outstanding Company Ordinary Share will be acquired by Ensco (and/or its DR Nominee (as defined in the Agreement), as applicable) and the holder
thereof will have the right to receive 2.215 Class&nbsp;A ordinary shares (the "Exchange Ratio") in the share capital of Ensco, par value $0.10 per share (the "Ensco Ordinary Shares") and
(ii)&nbsp;permits, effective immediately following the Closing (as defined in the Agreement), every four issued and outstanding Ensco Ordinary Shares shown in the register of members of Ensco
immediately following the update of such register to give effect to the provisions of the Scheme of Arrangement or completion of any Offer (as defined in the Agreement), as the case may be, to be
consolidated into one Ensco Ordinary Share, with a nominal value of $0.40 per Ensco Ordinary Share, as to which consolidation we express no opinion. The Agreement further provides that the Scheme of
Arrangement may be switched to an Offer in accordance with the terms set out in the Agreement. </FONT></P>

participated in certain of the negotiations leading to, the Transaction. We expect to receive fees for our services in connection with the Transaction, the principal portion of which is contingent
upon consummation of the Transaction, and the Company has agreed to reimburse certain of our expenses arising, and indemnify us against certain liabilities that may arise, out of our engagement. We
have provided certain financial advisory and/or underwriting services to the Company and/or its affiliates from time to time for which our Investment Banking Division has received, and may receive,
compensation, including having acted as financial advisor to the Company in connection with the formation of a joint venture by the Company and the Saudi Arabian Oil Company in November 2016 and as
joint book runner with respect to the Company's offering of 7.375% senior unsecured notes due 2025 (aggregate principal amount $500,000,000) in December 2016. We may also in the
future provide financial advisory and/or underwriting services to the Company, Ensco and their respective affiliates for which our Investment Banking Division may receive compensation. </FONT></P>

management, certain internal financial analyses and forecasts for Ensco stand alone prepared by its management, as adjusted by the management of the Company, and certain financial analyses and
forecasts for Ensco pro forma for the Transaction prepared by the management of the Company, in each case as approved for our use by the Company (the "Forecasts"), including certain operating
synergies projected by the management of the Company to result from the Transaction (the "Synergies"). We have also held discussions with members of the senior managements of the Company and Ensco
regarding the past and current business operations, financial condition and future prospects of Ensco and have held discussions with members of senior management of the Company regarding the past and
current business operations, financial condition and future prospects of the Company and their assessment of the strategic rationale for, and the potential benefits of, the Transaction; reviewed the
reported price and trading activity for the Company Ordinary Shares and the Ensco Ordinary Shares; compared certain financial and stock market information for the Company and Ensco with similar
information for certain other companies the securities of which are publicly traded; and performed such other studies and analyses, and considered such other factors, as we deemed appropriate. </FONT></P>

purposes of rendering this opinion, we have, with your consent, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and

consummation of the Transaction will be obtained without any adverse effect on the Company or Ensco or on the expected
benefits of the Transaction in any way meaningful to our analysis. We have assumed that the Transaction will be consummated on the terms set forth in the Agreement, without the waiver or modification
of any term or condition the effect of which would be in any way meaningful to our analysis. </FONT></P>

Transaction, including, the fairness of the Transaction to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors, or other constituencies
of the Company; nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Company, or class of such persons, in
connection with the Transaction, whether relative to the Exchange Ratio pursuant to the Agreement or otherwise. We are not expressing any opinion as to the prices at which the Ensco Ordinary Shares
will trade at any time or as to the impact of the Transaction on the solvency or viability of the Company or Ensco or the ability of the Company or Ensco to pay their respective obligations when they
come due. Our opinion is necessarily </FONT></P>
