DEFINITIONS AND CAUTIONARY NOTE

Resources: Our use of the term “resources” in this announcement includes quantities of oil and gas not yet classified as Securities and Exchange Commission of the United States ("SEC") proved oil and gas reserves or SEC proven mining reserves. Resources are consistent with the Society of Petroleum Engineers 2P and 2C definitions.

The companies in which Royal Dutch Shell plc directly and indirectly owns investments are separate entities. In this announcement "Shell", "Shell Group" and "Royal Dutch Shell" are sometimes used for convenience where references are made to Royal Dutch Shell plc and its subsidiaries in general. Likewise, the words "we", "us" and "our" are also used to refer to subsidiaries in general or to those who work for them. These expressions are also used where no useful purpose is served by identifying the particular company or companies. "Subsidiaries", "Shell subsidiaries" and "Shell companies" as used in this announcement refer to companies in which Shell either directly or indirectly has control, by having either a majority of the voting rights or the right to exercise a controlling influence. The companies in which Shell has significant influence but not control are referred to as "associated companies" or "associates" and companies in which Shell has joint control are referred to as "jointly controlled entities". In this announcement, associates and jointly controlled entities are also referred to as "equity-accounted investments". The term "Shell interest" is used for convenience to indicate the direct and/or indirect (for example, through our 23 per cent shareholding in Woodside Petroleum Ltd.) ownership interest held by Shell in a venture, partnership or company, after exclusion of all third-party interest.

This announcement contains forward looking statements concerning the financial condition, results of operations and businesses of Shell and the Shell Group. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements. Forward-looking statements are statements of future expectations that are based on management's current expectations and assumptions and involve known and unknown risks and uncertainties that could cause actual results, performance or events to differ materially from those expressed or implied in these statements. Forward-looking statements include, among other things, statements concerning the potential exposure of Shell and the Shell Group to market risks and statements expressing management’s expectations, beliefs, estimates, forecasts, projections and assumptions. These forward looking statements are identified by their use of terms and phrases such as "anticipate", "believe", "could", "estimate", "expect", "goals", "intend", "may", "objectives", "outlook", "plan", "probably", "project", "risks", "seek", "should", "target", "will" and similar terms and phrases. There are a number of factors that could affect the future operations of Shell and the Shell Group and could cause those results to differ materially from those expressed in the forward looking statements included in this announcement, including (without limitation): (a) price fluctuations in crude oil and natural gas; (b) changes in demand for Shell's products; (c) currency fluctuations; (d) drilling and production results; (e) reserves estimates; (f) loss of market share and industry competition; (g) environmental and physical risks; (h) risks associated with the identification of suitable potential acquisition properties and targets, and successful negotiation and completion of such transactions; (i) the risk of doing business in developing countries and countries subject to international sanctions; (j) legislative, fiscal and regulatory developments including regulatory measures addressing climate change; (k) economic and financial market conditions in various countries and regions; (l) political risks, including the risks of expropriation and renegotiation of the terms of contracts with governmental entities, delays or advancements in the approval of projects and delays in the reimbursement for shared costs; and (m) changes in trading conditions. All forward looking statements contained in this announcement are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. Readers should not place undue reliance on forward looking statements. Additional factors that may affect future results are contained in Shell's 20-F for the year ended 31 December 2012 (available at www.shell.com/investor and www.sec.gov ). These factors also should be considered by the reader. Each forward looking statement speaks only as of the date of this announcement, March 14, 2013. Neither Shell nor any of its subsidiaries nor the Shell Group undertake any obligation to publicly update or revise any forward looking statement as a result of new information, future events or other information. In light of these risks, results could differ materially from those stated, implied or inferred from the forward looking statements contained in this announcement.

Shell may have used certain terms, such as resources, in this announcement that the SEC strictly prohibits Shell from including in its filings with the SEC. U.S. investors are urged to consider closely the disclosure in Shell's Form 20-F, File No 1-32575, available on the SEC website www.sec.gov. You can also obtain these forms from the SEC by calling 1-800-SEC-0330.

Ursa Gas Pipeline Damage – A different Challenge

� Ursa Platform had minimal damage and was ready for re-

start

� No opportunity to shut-down pipeline for repairs

� A new and radical repair method (without production shut-in)


� Pipeline damaged by ship anchor drag

� Water dept at damage – 2,975 ft (907m)

� Damage found during ROV inspection

� Pressure integrity of pipeline not compromised

� Pipeline bent approximately 6 degrees

� Analysis and full scale testing indicate reduced fatigue life

due to damage

� Pipe is 20” x .750” Wall, DSAW, API 5LX-65

Ursa Pipeline Damage Report


� A unique 50,000 Lbs (25 t), 10 ft (3m) long Repair Clamp

� System for supporting clamp and pipeline� End Suction pile system with structural “Table” for supporting Pipeline

� Centre Suction pile with structural “Center Table” and “Clamp Serving Table”

� DSAW seam removal tool

� FBE removal tool

� Metrology tool

� Complex manufacturing and installation of repair system

Some Take-aways for Malaysia Industry (1/2)

� With expected growth in deep-water oil/gas pipeline assets, AP Regional

players need to consider the future requirements for emergency repairs of

critical pipeline systems

� A system similar to Shell’s GOM Deep-water Pipeline Repair System

(DPRS) would be a critical asset to Malaysia (and the Region’s) Pipeline

Integrity management system

� Malaysia has experience with joint-industry solutions through the

Petronas-led Pan-Malaysia execution model

� Similar joint-industry effort will be key to addressing the critical need for

a Deep-water Pipeline Repair System for Malaysia and the Region


Some Take-aways for Malaysia Industry (2/2)

� Some DW Pipeline component & product manufacturers have setup offices in

the region; an important key step by the contracting community

� Malaysia currently progressing a joint-Industry DPRS; a step in the right

direction

� Preservation maintenance is a big issue for DPRS’s. Regional synergies within

Asia (Philippines, Indonesia, Australia, etc) will lessen the burden of

preservation costs.

� A Regional DPRS system will present the challenge of usage priority. However,

the resultant value more than justifies the inherent challenge and can be

managed.
