BTG plc

("BTG")

by

Bravo Bidco Limited

("Bravo Bidco")

a newly incorporated entity indirectly wholly-owned by Boston Scientific Corporation ("Boston Scientific")

intended to be effected by means of a scheme of arrangement under Part 26 of the Companies Act

Summary

· The Boards of Boston Scientific, Bravo Bidco and BTG are pleased to announce that they have reached agreement on the terms of a recommended cash offer by Bravo Bidco for the acquisition of the entire issued and to be issued ordinary share capital of BTG (the "Acquisition"). The Acquisition is intended to be effected by means of a scheme of arrangement under Part 26 of the Companies Act (the "Scheme").

· Under the terms of the Acquisition, BTG Shareholders will be entitled to receive:

for each BTG Share: 840 pence in cash (the "Offer Price")

· The Offer Price values the entire issued and to be issued ordinary share capital of BTG at approximately £3.3 billion and represents a premium of approximately:

o 36.6 per cent. to the closing price of 615 pence per BTG Share on 19 November 2018 (being the last Business Day before this Announcement); and

o 51.0 per cent. to the BTG 90 trading day volume-weighted average share price for the period ended 19 November 2018 (being the last Business Day before this Announcement).

· If any dividend or other distribution is authorised, declared, made or paid in respect of the BTG Shares on or after the date of this Announcement and prior to the Effective Date, Bravo Bidco reserves the right to reduce the Offer Price by the amount of all or part of any such dividend or other distribution.

Recommendation

· The BTG Directors, who have been so advised by Goldman Sachs International, J.P. Morgan Cazenove and Rothschild & Co as to the financial terms of the Acquisition, each consider the terms of the Acquisition to be fair and reasonable. In providing their financial advice to the BTG Directors, each of Goldman Sachs International, J.P. Morgan Cazenove and Rothschild & Co has taken into account the commercial assessments of the BTG Directors.

· Accordingly, the BTG Directors intend to recommend unanimously that BTG Shareholders vote (or procure the voting) in favour of the Scheme at the Court Meeting and the Resolution to be proposed at the General Meeting (or, in the event that the Acquisition is implemented by way of a Takeover Offer, to accept or procure acceptance of the Takeover Offer), as each BTG Director holding BTG Shares has irrevocably undertaken to do in respect of their entire beneficial holdings of 969,032 BTG Shares, representing in aggregate approximately 0.3 per cent. of the issued ordinary share capital of BTG on the Last Practicable Date.

Irrevocable Undertakings and Support for the Acquisition

· In addition to the irrevocable undertakings received from BTG Directors holding BTG Shares referred to above, Bravo Bidco has received irrevocable undertakings to vote (or to procure the voting) in favour of the Scheme at the Court Meeting and the Resolution to be proposed at the General Meeting (or, in the event that the Acquisition is implemented by way of a Takeover Offer, to accept or procure acceptance of the Takeover Offer) from Invesco Asset Management Limited, Novo Holdings A/S and Woodford Investment Management Limited in respect of a total of 127,062,586 BTG Shares, representing, in aggregate, approximately 32.8 per cent. of the share capital of BTG in issue on the Last Practicable Date.

· In aggregate, therefore, Bravo Bidco has received irrevocable undertakings in respect of 128,031,618 BTG Shares, representing approximately 33.1 per cent. of the share capital of BTG in issue on the Last Practicable Date.

· Further details of these irrevocable undertakings are set out in Appendix III to this Announcement.

Comments on the Acquisition

Commenting on the Acquisition, Michael F. Mahoney, the Chairman and Chief Executive Officer of Boston Scientific said:

"The acquisition of BTG and its rapidly growing peripheral interventional portfolio is an exciting extension of our category leadership strategy that will augment our capabilities in important areas of unmet need such as cancer and pulmonary embolism. We are confident that the addition of these therapies to our portfolio will ultimately advance patient care in ways that could not be realised by either company alone, while also allowing us to realise substantial synergies and provide a strong return for investors."

Commenting on the Acquisition, Garry Watts, the Chairman of BTG said:

"Under the leadership of Louise Makin and the broader management team, BTG has developed into a global healthcare company with a leading Interventional Medicine platform. We believe Boston Scientific's offer represents an attractive proposition for BTG Shareholders with a significant premium in cash and recognises the value created by the support of our long term large shareholders. We are proud of what BTG has become and of all BTG employees for their contributions."

Commenting on the Acquisition, Louise Makin, the Chief Executive Officer of BTG said:

"I would like to thank and acknowledge all BTG colleagues for building a leading global healthcare company. Our Interventional Medicine portfolio delivers value to patients and is a significant growth driver for the business, and we're also proud of our highly profitable pharmaceuticals business focused on critical care products.

We remain committed to transforming patient care through our passion for people, relentless curiosity, and ambition to lead the way. Boston Scientific shares that vision, and their comprehensive clinical and commercial expertise will accelerate the delivery of our strategy and expand the global reach of our Interventional Medicine portfolio. The strong strategic and cultural fit between the companies gives me confidence that our business will continue to make a real difference for our patients, customers, employees and wider stakeholders."

In particular, the ability of persons who are not resident in the United Kingdom or who are subject to the laws of another jurisdiction to vote their Scheme Shares with respect to the Scheme at the Court Meeting, or to execute and deliver Forms of Proxy appointing another to vote at the Court Meeting on their behalf, may be affected by the laws of the relevant jurisdictions in which they are located.

Notice to US Investors in BTG

The Acquisition relates to the shares of a company organised under the laws of England and Wales and is proposed to be effected by means of a scheme of arrangement under the laws of England and Wales (Part 26 of the Companies Act). This Announcement, the Scheme Document and certain other documents relating to the Acquisition have been or will be prepared in accordance with English law, the Code and UK disclosure requirements, format and style, all of which differ from those in the United States. A transaction effected by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the US Securities Exchange Act of 1934, as amended (the "US Exchange Act"). Accordingly, the Acquisition is subject to the disclosure requirements of and practices applicable in the United Kingdom to schemes of arrangement involving a target company in England listed on the London Stock Exchange, which differ from the disclosure requirements of the United States tender offer and proxy solicitation rules. Bravo Bidco reserves the right, subject to the prior consent of the Panel, to elect to implement the Acquisition by way of a Takeover Offer. If, in the future, Bravo Bidco exercises its right to implement the Acquisition by way of a Takeover Offer and determines to extend the Takeover Offer into the United States, such offer and the Acquisition will be made in compliance with applicable US tender offer regulations.

If the Acquisition is implemented by way of a Takeover Offer, pursuant to Rule 14e-5(b) under the US Exchange Act, Bravo Bidco, certain affiliated companies or their nominees or brokers (acting as agents) may from time to time make certain purchases of, or arrangements to purchase, shares in BTG outside such a Takeover Offer during the period in which such a Takeover Offer would remain open for acceptance. If such purchases or arrangements to purchase were to be made, they would be made outside the US and would apply in accordance with applicable law, including the US Exchange Act and the Code. Such purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases will be disclosed as required in the United Kingdom, will be reported to the Regulatory News Service of the London Stock Exchange and will be available on the London Stock Exchange website at: http://www.londonstockexchange.com/prices-and-news/prices-news/home.htm.

BTG's financial statements, and all financial information that is included in this Announcement or that may be included in the Scheme Document, or any other documents relating to the Acquisition, have been or will be prepared in accordance with non-US accounting standards that may not be comparable to financial information of companies in the United States or other companies whose financial statements are prepared in accordance with US generally accepted accounting principles.

Neither the United States Securities and Exchange Commission nor any US state securities commission has approved or disapproved the Acquisition, passed upon the merits or fairness of the Acquisition or passed any opinion upon the accuracy, adequacy or completeness of this Announcement or the Scheme Document. Any representation to the contrary is a criminal offence in the United States.

BTG is incorporated under the laws of England and Wales. In addition, some of its officers and directors reside outside the United States, and some or all of its assets are or may be located in jurisdictions outside the United States. Therefore, investors may have difficulty effecting service of process within the United States upon those persons or recovering against BTG or its officers or directors on judgments of United States courts, including judgments based upon the civil liability provisions of the United States federal securities laws. It may not be possible to sue BTG or its officers or directors in a non-U.S. court for violations of the U.S. securities laws.

The receipt of cash pursuant to the Acquisition by US holders of BTG Shares as consideration for the transfer of its Scheme Shares pursuant to the Scheme may be a taxable transaction for US federal income tax purposes and under applicable US state and local, as well as foreign and other, tax laws. Each US holder of BTG Shares is urged to consult his or her independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to him or her.

All statements other than statements of current or historical fact, are or may be deemed to be, forward-looking statements. Forward-looking statements are based on current expectations and projections about future events and are therefore subject to known and unknown risks and uncertainties which could cause actual results, performance or events to differ materially from the future results, performance or events expressed or implied by the forward-looking statements. Often, but not always, forward-looking statements can be identified by the use of forward-looking words such as "plans", "expects", "is expected", "is subject to", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", "believes", "targets", "aims", "projects", "goal", "objective", "outlook", "risks", "seeks" or words or terms of similar substance or the negative thereof, as well as variations of such words and phrases or statements that certain actions, events or results "may", "could", "should", "would", "might", "probably" or "will" be taken, occur or be achieved. Such statements are qualified in their entirety by the inherent risks and uncertainties surrounding future expectations.

Such forward-looking statements involve risks and uncertainties that could significantly affect expected results and are based on certain key assumptions. Many factors could cause actual results to differ materially from those projected or implied in any forward-looking statements. Due to such uncertainties and risks, readers are cautioned not to place undue reliance on such forward-looking statements, which speak only as of the date of this Announcement. Any forward-looking statements made in this Announcement on behalf of BTG, Bravo Bidco or Boston Scientific are made as of the date of this Announcement based on the opinions and estimates of directors of BTG, Bravo Bidco or Boston Scientific, respectively and no assurance can be given that such opinions or estimates will prove to have been correct.

Rounding

Certain figures included in this Announcement have been subjected to rounding adjustments. Accordingly, figures shown for the same category presented in different tables may vary slightly and figures shown as totals in certain tables may not be an arithmetic aggregation of the figures that precede them.

No profit forecasts or estimates

Nothing in this Announcement is intended or shall be deemed to be a forecast, projection or estimate of the future financial performance of BTG, Boston Scientific or Bravo Bidco for any period and no statement in this Announcement should be interpreted to mean that cash flow from operations, earnings, or earnings per share or income of those persons (where relevant) for the current or future financial years would necessarily match or exceed the historical published cash flow from operations, earnings, earnings per share or income of those persons (as appropriate).

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1 per cent. or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the Offer Period and, if later, following the Announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3:30 pm (London time) on the 10th Business Day following the commencement of the Offer Period and, if appropriate, by no later than 3:30 pm (London time) on the 10th Business Day following the Announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1 per cent. or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror, save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 pm (London time) on the Business Day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will normally be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4). Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the Offer Period commenced and when any offeror was first identified.

20 November 2018

RECOMMENDED CASH OFFER

for

BTG plc

("BTG")

by

Bravo Bidco Limited

("Bravo Bidco")

a newly incorporated entity indirectly wholly-owned by Boston Scientific Corporation ("Boston Scientific")

intended to be effected by means of a scheme of arrangement under Part 26 of the Companies Act

1. Introduction

The Boards of Boston Scientific, Bravo Bidco and BTG are pleased to announce that they have reached agreement on the terms of a recommended cash offer by Bravo Bidco for the acquisition of the entire issued and to be issued ordinary share capital of BTG (the "Acquisition"). The Acquisition is intended to be effected by means of a scheme of arrangement under Part 26 of the Companies Act (the "Scheme").

2. The Acquisition

Under the terms of the Acquisition, which will be subject to the Conditions and further terms set out in Appendix I to this Announcement and to be set out in the Scheme Document, BTG Shareholders will be entitled to receive:

for each BTG Share: 840 pence in cash (the "Offer Price")

The Offer Price values the entire issued and to be issued ordinary share capital of BTG at approximately £3.3 billion and represents a premium of approximately:

· 36.6 per cent. to the closing price of 615 pence per BTG Share on 19 November 2018 (being the last Business Day before this Announcement); and

· 51.0 per cent. to the BTG 90 trading day volume-weighted average share price for the period ended 19 November 2018 (being the last Business Day before this Announcement).

The BTG Shares to be acquired under the Acquisition will be acquired fully paid and free from all liens, charges, equitable interests, encumbrances, rights of pre-emption and any other rights and interests of any nature whatsoever and together with all rights now and hereafter attaching thereto.

If any dividend or other distribution is authorised, declared, made or paid in respect of BTG Shares on or after the date of this Announcement and prior to the Effective Date, Bravo Bidco reserves the right to reduce the Offer Price by the amount of all or part of any such dividend or other distribution.

3. Background to and reasons for the Acquisition

Boston Scientific is one of the largest independent medical technology companies in the world with a wide range of product offerings that address unmet patient needs across multiple medical conditions. Boston Scientific possesses a long history of growth through internal innovation complemented by selective acquisitions and regularly reviews opportunities for its diverse set of businesses.

Boston Scientific believes that the Acquisition represents a compelling opportunity to build upon the strengths of Boston Scientific's $1.2 billion Peripheral Interventions Division with the addition of BTG's high growth and complementary interventional medicine platform.

In addition, BTG's pharmaceutical business adds a profitable portfolio of lifesaving acute care drugs, and its licensing business adds a portfolio of profitable licensed pharmaceutical products that generate a stream of royalties with minimal infrastructure requirements.

Boston Scientific's comprehensive and global research and development, clinical and commercial expertise combined with BTG's strong positions in growing areas of interventional oncology and interventional vascular will position the combined entity to better serve patients, payors and providers around the world.

In particular, Boston Scientific expects the Acquisition to deliver short and long-term benefits, including:

· strengthening Boston Scientific's offerings in the area of cancer treatment with the addition of BTG's highly differentiated interventional oncology segment that will enable Boston Scientific to expand treatment options for cancer patients worldwide;

· advancing Boston Scientific's category leadership strategy in the Peripheral Interventions segment by adding high growth revenues ($341 million for the 12 month period ending September 30, 2018) to Boston Scientific's existing Peripheral Interventions Division;

· expanding Boston Scientific's venous portfolio offering by adding BTG's pulmonary embolism franchise in addition to other highly differentiated vascular products;

· providing a strong return to Boston Scientific's investors, including by adding two to three cents of accretion to Boston Scientific's adjusted earnings per share in 2019, and increasing levels of accretion thereafter; and

· delivering significant revenue and cost synergies through Boston Scientific's enhanced global manufacturing capabilities and Boston Scientific's and BTG's combined geographic footprint.

Boston Scientific is confident in its ability to deliver on its strategy for the Acquisition, having demonstrated a strong track record of integrating acquisitions into its organisation and driving both revenue growth and operating improvements through more than 20 acquisitions in the past five years.

4. Background to and reasons for the BTG Directors' Recommendation

Since its floatation in 1995, BTG has developed into a global specialist healthcare company. Under the leadership of Louise Makin and the management team, a key element of BTG's strategy in the past decade has been to develop a leading and scalable Interventional Medicine portfolio to bring patients a set of innovative medical technologies enabling minimally invasive, often image guided, procedures. Today BTG's Interventional Medicine portfolio represents a significant growth driver for the business and one of the few well-developed scale platforms in the market. Alongside Interventional Medicine, BTG also benefits from its highly profitable pharmaceuticals business focused on critical care products, as well as royalties from legacy intellectual property licencing arrangements. BTG has delivered a compelling financial performance with revenue, operating profit and adjusted earnings per share growth of 9 per cent., 18 per cent., and 42 per cent., respectively, for the financial year ended 31 March 2018. This strong growth was reinforced in the results for the six month period ended 30 September 2018, which were announced on 13 November 2018. When combined with the continued scaling of the Interventional Medicine business and its strong financial profile, the BTG Directors remain highly confident that the ongoing successful execution of its strategy would provide long-term growth and create significant value for shareholders.

The BTG Directors believe that BTG has a clear strategy and strong independent future. However, following the approach from Boston Scientific, the BTG Directors have held detailed discussions regarding the terms of the potential Acquisition. These discussions resulted in the Offer Price of 840 pence in cash for each Ordinary Share.

In assessing the terms of the Acquisition, the BTG Directors considered the all-cash nature of the consideration, which would provide BTG Shareholders with the opportunity to receive an immediate and certain value in cash, that would otherwise potentially be unlocked over a longer period of time as BTG executes its strategy and realises its longer term potential, whilst taking into account the inherent execution risks. These risks include an uncertain macro and regulatory and reimbursement environment, patent challenges or expiries, potential novel or generic competition on products, potential failure of clinical trials, commercialisation risk on innovation, competition from larger players in various markets and ongoing integration of M&A.

In addition, the BTG Directors note:

· the terms of the Acquisition represents a premium of:

o approximately 36.6 per cent. to the Closing Price per BTG Share of 615 pence on 19 November 2018 (being the Business Day before this Announcement); and

o approximately 51.0 per cent. to the 90 trading day volume-weighted average price per BTG Share of 556 pence for the period ended 19 November 2018 (being the Business Day before this Announcement);

· the terms of the Acquisition provide a vehicle for BTG Shareholders to monetise their shares in BTG without suffering an illiquidity discount; and

· the BTG Directors believe that the terms of the Acquisition provide fair value for BTG Shareholders relative to the standalone prospects of BTG or alternative strategies for realising value from the BTG Group's assets.

In addition, the BTG Directors have also considered the interests of its shareholders, employees, customers and patients. The BTG Directors believe that under Boston Scientific's ownership, BTG would be able to accelerate the delivery of its strategy and further enhance its growth profile through combining the Interventional Medicine business with Boston Scientific's Peripheral Interventions business and leveraging Boston Scientific's comprehensive and global clinical and commercial expertise, allowing for the global roll-out of BTG's Interventional Medicine portfolio. As part of Boston Scientific, BTG would have the opportunity to benefit from enhanced scale and financial resources, which should enable further innovation to address unmet needs for patients. BTG is also aware of Boston Scientific's track record of successfully integrating businesses and it therefore believes there is a strong strategic and cultural fit with Boston Scientific for its customers, employees and wider stakeholders.

5. Recommendation by BTG Directors

The BTG Directors, who have been so advised by Goldman Sachs International, J.P. Morgan Cazenove and Rothschild & Co as to the financial terms of the Acquisition, each consider the terms of the Acquisition to be fair and reasonable. In providing their financial advice to the BTG Directors, each of Goldman Sachs International, J.P. Morgan Cazenove and Rothschild & Co has taken into account the commercial assessments of the BTG Directors.

Accordingly, the BTG Directors intend to recommend unanimously that BTG Shareholders vote (or procure the voting) in favour of the Scheme at the Court Meeting and the Resolution to be proposed at the General Meeting (or in the event that the Acquisition is implemented by way of a Takeover Offer, to accept or procure acceptance of the Takeover Offer), as each BTG Director holding BTG Shares has irrevocably undertaken to do in respect of their entire beneficial holdings of 969,032 BTG Shares, in aggregate, representing approximately 0.3 per cent. of the issued ordinary share capital of BTG on the Last Practicable Date.

Further details of these irrevocable undertakings are set out in Appendix III to this Announcement.

6. Irrevocable Undertakings and Support for the Acquisition from other BTG Shareholders

In addition to the irrevocable undertakings received from BTG Directors referred to above, Bravo Bidco has received irrevocable undertakings to vote (or to procure the voting) in favour of the Scheme at the Court Meeting and the Resolution to be proposed at the General Meeting (or, in the event that the Acquisition is implemented by way of a Takeover Offer, to accept or procure acceptance of the Takeover Offer) from Invesco Asset Management Limited, Novo Holdings A/S and Woodford Investment Management Limited in respect of a total of 127,062,586 BTG Shares, representing, in aggregate, approximately 32.8 per cent. of the share capital of BTG in issue on the Last Practicable Date.

In aggregate, therefore, Bravo Bidco has received irrevocable undertakings in respect of 128,031,618 BTG Shares, representing approximately 33.1 per cent. of the share capital of BTG in issue on the Last Practicable Date.

Further details of these irrevocable undertakings are set out in Appendix III to this Announcement.

7. Conditions to the Acquisition

The Acquisition will be subject to the Conditions and certain further terms set out in Appendix I to this Announcement, including:

Bravo Bidco is a newly incorporated indirectly wholly-owned subsidiary of Boston Scientific formed for the purpose of implementing the Acquisition.

9. Information on BTG

BTG, headquartered in London, United Kingdom, is a global healthcare company focused on Interventional Medicine, with a fast-growing Oncology and Vascular portfolio to advance the treatment of cancer, blood clots and varicose veins through minimally invasive procedures. Alongside Interventional Medicine, BTG has a cash-generative Pharmaceuticals business that provides life-saving products to treat patients overexposed to certain medications or toxins. Inspired by patient and physician needs, BTG is expanding its portfolio to address some of today's most complex healthcare challenges.

BTG was formed in 1981 from the merger of the UK government's National Research & Development Council and National Enterprise Board. Since its flotation on the London Stock Exchange in 1995, the group has built the capabilities and infrastructure to support ongoing business growth globally. BTG has a significant direct commercial presence in Europe and the US, supporting the group's growth and geographic expansion. BTG continues to develop its product portfolio through investments in pipeline innovation and clinical studies, as well as through a focused acquisition strategy. BTG operates two businesses: Interventional Medicine and Pharmaceuticals. It also receives royalties from legacy Licensing activities.

Interventional Medicine: BTG is a leader in Interventional Medicine therapies, the fast growing field of minimally invasive, often image-guided procedures used to treat a range of conditions, focused on Oncology and Vascular segments. Interventional Oncology offers treatments for a variety of cancers and tumours. Key products include TheraSphere®, glass microspheres that deliver internal radiation therapy; LC Bead® and DC Bead®, embolization and chemoebolization polymer beads; and BTG cryoablation systems. This unique portfolio gives BTG the ability to offer customers minimally invasive treatment alternatives to systemic radiotherapy, chemotherapy or open surgery. The Vascular portfolio focuses on the treatment of blood clots and varicose veins. Key products include EKOS®, an ultrasonic device to help dissolve blood clots, BTG crossing devices, anchoring catheters used to cross complex lesions, and venous filters, as well as Varithena®, an injectable microfoam for the treatment of varicose veins.

Pharmaceuticals: BTG's products are used in hospital emergency rooms and intensive care units. The products typically address conditions with small patient populations for which there are limited or no existing treatment options. Key products within the pharmaceuticals portfolio include CroFab®, DigiFab® and Voraxaze® that are used respectively for the treatment of envenomation by certain snakes and overexposure to particular heart and cancer medications.

Licensing: in addition to generating revenues from its own products, BTG earns royalties on products sold by its licensees. Licensed products include Zytiga®, licensed to Johnson & Johnson and used for the treatment of prostate cancer, and the Two-Part Hip Cup, a prosthetic hip joint replacement.

For the six months ended 30 September 2018 (the "1H 2018/19 Fiscal Year"), BTG generated sales of $495.7m (+12% vs six months ended 30 September 2017 (the "1H 2017/18 Fiscal Year")) of which $340.2m was from product sales (+10% vs 1H 2017/18 Fiscal Year) and $155.5m from licensing revenues (+18% vs 1H 2017/18 Fiscal Year). Group adjusted profit was $178.5m (+39% vs 1H 2017/18 Fiscal Year) representing a 36% adjusted profit margin. For 1H 2018/19 Fiscal Year Interventional Medicine generated $172.3m (+12% vs 1H 2018 Fiscal Year), of which $110.9m was from Oncology (+12% vs 1H 2017/18 Fiscal Year) and $59.2m from Vascular (+20% vs 1H 2017/18 Fiscal year) while Pharmaceuticals generated $167.9m (+7% vs 1H 20/1718 Fiscal Year). Net cash and cash equivalents was $285.2m as at 30 September 2018.

On 4 October 2018, BTG announced that Garry Watts had informed the BTG Board that he wished to retire as Chairman and as a non-executive director of BTG at the end of 2018. Given the Acquisition, it is now expected that he will remain as Chairman and as a non-executive director until the Effective Date.

10. Post-Offer Intentions with regard to the Business, Employees and Pension Schemes

Boston Scientific values BTG's culture, reputation with customers, its commitment to quality and its focus on addressing unmet patient needs through innovation and product excellence. Boston Scientific and BTG have highly complementary businesses in the area of interventional medicine. Boston Scientific plans to apply the combined group's expertise across therapeutic areas, research and development capabilities, and all employee talents to provide innovative solutions for patients, benefits for stakeholders and growth for shareholders.

Boston Scientific's due diligence review of BTG has primarily consisted of a detailed review of publicly available information regarding BTG, since it signed a Confidentiality Agreement with BTG on 31 October 2018, limited interactions with a narrow group of BTG's senior management, and review of the limited materials provided to it by BTG. Boston Scientific, because of its own Peripheral Interventions business and its track record of acquiring and integrating other businesses, also is familiar with businesses similar to BTG's and the integration process. Based on this review, its industry and transactional experience, and its own Peripheral Interventions business, Boston Scientific believes there will be meaningful duplication of operational infrastructure between the two businesses, primarily in the area of Interventional Medicine. Boston Scientific has not yet received sufficiently detailed information to formulate comprehensive plans or intentions regarding the impact of the Acquisition on BTG and, accordingly, intends to take a 'best of both' approach in optimising the operating structure of the combined Peripheral Interventions business.

Boston Scientific possesses extensive operations around the world, including its global headquarters in Marlborough, Massachusetts, which it will retain following the completion of the Acquisition, and a significant operational presence in Maple Grove, Minnesota. It expects to realise synergies from the Acquisition by eliminating duplication across functions, including eliminating BTG's public company infrastructure and listing costs. Boston Scientific also expects to eliminate other duplicative general and administrative costs, including by reducing headcount and by combining or relocating BTG's remaining head office functions with or to Boston Scientific facilities.

Boston Scientific also expects to realise synergies by increasing manufacturing and supply chain efficiencies, which are expected to include reduction of manufacturing footprint by re-deploying or disposing of fixed assets. Whether these fixed assets will be re-deployed or disposed of will depend on the nature of these assets, including how efficient they are. As part of its post-closing evaluation, Boston Scientific will also review BTG's research and development activities. Boston Scientific expects to conduct this review promptly after completion of the Acquisition with the goal of identifying BTG's promising pipeline projects and duplicative facilities and headcount. Following completion of this review, Boston Scientific expects to preserve and enhance the development of BTG's promising pipeline products and to eliminate less promising pipeline products, as well as duplicative facilities and headcount.

Boston Scientific expects to implement expense reductions across a range of operating functions in the combined Peripheral Interventions business. Based on its limited due diligence to date, it does not yet have sufficient information to be able to estimate with specificity the extent or location of these reductions.

Based on its experience integrating other acquired businesses, subject to complying with applicable laws, Boston Scientific expects to be able to begin to develop detailed steps for the integration of the Boston Scientific and BTG businesses in the period prior to the completion of the Acquisition, and to finalise its integration plan within six to nine months after completion of the Acquisition.

Boston Scientific also expects to realise revenue synergies in its Peripheral Interventions and BTG's Interventional Medicine businesses by driving incremental top-line growth through a larger combined, global commercial team and by leveraging Boston Scientific's significant presence outside the United States.

Based on the limited information it has received to date and its experience integrating other acquired companies and operating similar businesses, Boston Scientific expects to realise annual cost and revenue synergies of approximately US $175 million by the end of 2021, largely consisting of cost synergies, a significant portion of which are expected to come from headcount reductions. Because of the limited due diligence Boston Scientific has been permitted to conduct to date, and its intention to take a "best of both" approach to integration, Boston Scientific cannot yet say what the total number of headcount reduction will be or the proportion of the expected headcount reductions that will come from BTG or from Boston Scientific. If a large portion of the headcount reductions were to come from BTG, they would be material to BTG.

Boston Scientific has yet to formulate its long-term plans with respect to BTG's Pharmaceuticals business. In the meantime, Boston Scientific intends to operate this business in substantially the same manner as it is currently operated.

The finalisation and implementation of any workforce reductions will be subject to comprehensive planning and engagement with employees and consultation with employee representatives as required by applicable local law. Any affected employees will be treated in a fair and equitable manner consistent with Boston Scientific's high standards and culture of respect.

Boston Scientific has agreed that, in implementing any headcount reductions, it would enhance that part of BTG's existing US severance policy that relates to minimum severance payments and make it applicable to both US and non-US employees so that BTG's general employees (i.e. employees below management other than professional and sales employees) would receive a minimum of ten weeks' pay (including pay for any notice period), and BTG's professional and sales employees would receive a minimum of 14 weeks' pay (including pay for any notice period). Severance payments would be paid in a lump sum rather than as salary continuation as is currently provided under BTG's US severance policy. Boston Scientific intends to approach employee integration with the aim of retaining and motivating the best talent across the combined company to further enhance a high performance organisation. Boston Scientific intends to inform all BTG employees as to whether they will have permanent positions going forward as soon as reasonably practicable following completion of the Acquisition.

Boston Scientific confirms that it has given assurances to the BTG Directors that upon and following completion of the Acquisition, it intends to fully observe the existing contractual employment rights, including pension rights, of all BTG management and employees. In addition, Boston Scientific has committed that, for the first twelve months after completion of the Acquisition, the terms and conditions of employment of BTG employees will be no less favourable (taking into account salary and benefits) than their existing terms and conditions of employment, except that Boston Scientific will provide incentive compensation arrangements to BTG employees that are consistent with Boston Scientific's compensation schemes, having regard to BTG's current incentive arrangements and Boston Scientific's desire to attract and retain BTG's talented employees.

BTG has also stated its intention to put in place retention arrangements for certain of its employees, under which it is expected that it will make additional cash retention awards in an aggregate amount of up to £18 million to employees whose retention is considered by BTG, following consultation with Boston Scientific in certain cases, to be critical for achieving the successful completion of the Acquisition and business continuity through and following the completion of the Acquisition.

Subject to the assurances Boston Scientific has provided to BTG as described above, following the completion of the Acquisition, Boston Scientific expects to migrate all BTG's management and employees on to the standard terms, conditions and benefits offered to Boston Scientific's management and employees, such that Boston Scientific's and BTG's management and employees are treated equally. However, except as otherwise required by applicable law, Boston Scientific does not provide pension benefits to its employees. Boston Scientific has not yet had sufficient access to BTG's benefit plans to be able to determine whether this migration will commence within the first 12 months after completion of the Acquisition or after this 12-month period. Pending this migration, Boston Scientific does not intend to make any changes with regard to employer contributions to BTG's existing pension schemes or the accrual of benefits to existing members or the admission of new members to such pension schemes. Subject to the potential headcount reductions described herein, Boston Scientific does not intend to make any material changes to the balance of the skills and functions of the employees and management of BTG.

No statements in this Paragraph 10 constitute "post-offer undertakings" for the purposes of Rule 19.5 of the Code.

11. Financing arrangements

Boston Scientific will provide Bravo Bidco with the cash consideration to be paid to BTG Shareholders pursuant to the Acquisition from new third party borrowing by Boston Scientific to be entered into prior to the Effective Date.

For cash confirmation purposes, Boston Scientific has obtained a bridge facility from Barclays Bank PLC for the full amount of the cash consideration required. Boston Scientific has committed to Barclays to provide Bravo Bidco with the cash consideration to be paid to the BTG Shareholders pursuant to the Acquisition.

Under the terms of such bridge facility, Boston Scientific has agreed that it will not amend, treat as satisfied or waive any term or condition without the consent of Barclays Bank PLC as lead arranger (such consent not to be unreasonably withheld, conditioned or delayed) if to do so would be materially adverse to the interests of the lenders under the relevant credit agreement, save as required pursuant to the City Code, the Panel, a competent regulatory authority or by the Court.

Barclays, in its capacity as financial adviser to Bravo Bidco and Boston Scientific, is satisfied that resources available to Bravo Bidco are sufficient to satisfy, in full, the cash consideration payable to BTG Shareholders under the terms of the Acquisition.

12. Structure of the Acquisition and the Scheme Document

Scheme

It is intended that the Acquisition will be effected by a Court-sanctioned scheme of arrangement between BTG and the Scheme Shareholders under Part 26 of the Companies Act. The intention of the Scheme is to enable Bravo Bidco to become the owner of the whole of the issued and to be issued share capital of BTG.

Under the Scheme, the Scheme Shares will be transferred to Bravo Bidco and in consideration the Scheme Shareholders will receive the consideration on the basis set out in paragraph 2 of this Announcement. The Scheme will be subject to the Conditions and further terms and conditions referred to in Appendix I to this Announcement and to be set out in the Scheme Document. The Acquisition will lapse if the Scheme does not become Effective by the Long Stop Date.

Approval by the Court Meeting and the General Meeting

In order to become Effective, the Scheme requires the approval of the Scheme Shareholders by the passing of a resolution at the Court Meeting. The resolution must be approved by a majority in number of the Scheme Shareholders present and voting and entitled to vote, either in person or by proxy, representing not less than 75 per cent. in value of the Scheme Shares held by such Scheme Shareholders. At the Court Meeting, voting will be by poll and not on a show of hands.

In addition, a special resolution must be passed at the General Meeting to approve amendments to BTG's articles of association to ensure that any BTG Shares issued after the approval of the Scheme at the Court Meeting and the Scheme Record Time will be: (i) subject to the Scheme; and (ii) automatically acquired by Bravo Bidco on the same terms as under the Scheme), which requires the approval of BTG Shareholders representing at least 75 per cent. of the votes cast at the General Meeting (either in person or by proxy). The General Meeting will be held immediately after the Court Meeting.

Application to the Court to sanction the Scheme

Once the necessary approvals have been obtained at the BTG Meetings, and the other Conditions (save for the Conditions set out at paragraphs 1(c) and (d) of Part A of Appendix I to this Announcement) have been satisfied or (where applicable) waived, in order for the Scheme to be capable of becoming Effective, it must be sanctioned by the Court at the Scheme Court Hearing.

The Scheme will only become Effective on delivery of the Scheme Court Order to the Registrar of Companies. 

Scheme becoming Effective

Subject to the satisfaction or (where applicable) waiver of the Conditions, the Scheme is expected to become Effective around mid-2019.

Upon the Scheme becoming Effective, it will be binding on all Scheme Shareholders, irrespective of whether or not they attended or voted at the Court Meeting or General Meeting, or whether they voted in favour of or against the Scheme. 

The Offer Price will be despatched by Bravo Bidco to Scheme Shareholders no later than 14 days after the Effective Date. Share certificates in respect of BTG Shares will cease to be valid and entitlements to BTG Shares held within the CREST system will be cancelled.

Scheme Document

The Scheme Document will include full details of the Scheme, together with notices of the Court Meeting and the General Meeting and the expected timetable for the Scheme, and will specify the action to be taken by BTG Shareholders.

It is expected that the Scheme Document, together with the Forms of Proxy, will be despatched to BTG Shareholders and, for information only, to participants in the BTG Share Plans as soon as reasonably practicable.

General

The Scheme will be governed by the laws of England and Wales. The Scheme will be also subject to the applicable requirements of the Code, the Panel, the London Stock Exchange and the Financial Conduct Authority.

13. Disclosure of interests in BTG Shares

As at close of business on the Last Practicable Date, save for the irrevocable undertakings referred to in Sections 5 and 6 of this Announcement, none of Bravo Bidco, Boston Scientific or any of their respective directors, or, so far as Boston Scientific is aware, any persons acting in concert (as such term is defined in the Code) with Boston Scientific had:

· any interest in, or right to subscribe for, any relevant securities of BTG;

· any short position in (whether conditional or absolute and whether in the money or otherwise), including any short position under a derivative, any agreement to sell or any delivery obligation or right to require another person to purchase or take delivery of, relevant securities of BTG;

· procured an irrevocable commitment or letter of intent to accept the terms of the Acquisition in respect of relevant securities of BTG; or

· borrowed or lent any such securities.

Furthermore, save for the irrevocable undertakings described in Sections 5 and 6 of this Announcement, no arrangement exists between Boston Scientific, Bravo Bidco or any person acting in concert (as such term is defined in the Code) with Boston Scientific or Bravo Bidco and any other person in relation to BTG Shares. For these purposes, an arrangement includes any indemnity or option arrangement, any agreement or understanding, formal or informal, of whatever nature, relating to BTG Shares which may be an inducement to deal or refrain from dealing in such securities.

In the interests of maintaining confidentiality, it has not been possible for Bravo Bidco to complete its enquiries in respect of the interests in BTG Shares (if any) of all of Bravo Bidco's concert parties in advance of the release of this Announcement. Enquiries of such parties will be completed as soon as practicable following the date of this Announcement. In accordance with Note 2(a)(i) on Rule 8 of the Code, further disclosures, if any, required in respect of such parties will be made as soon as possible and in any event by no later than 12 noon (London time) on the date falling 10 Business Days after the date of this Announcement.

14. BTG Share Plans

Participants in the BTG Share Plans will be contacted regarding the effect of the Acquisition on their rights under the BTG Share Plans and appropriate proposals will be made to such participants in due course. Further details of the terms of such proposals will be included in the Scheme Document and separate proposal documentation.

15. Acquisition-related Arrangements

Confidentiality agreement

On 31 October 2018, Boston Scientific and BTG entered into a confidentiality agreement in relation to the Acquisition, pursuant to which Boston Scientific undertook to keep information related to BTG confidential and to not disclose it to third parties (other than to permitted persons) unless required by law or regulation. Unless terminated earlier, the confidentiality obligations will remain in force for five years from the date of the agreement.

The confidentiality agreement also contains undertakings from Boston Scientific that, for a period of 12 months from the date of the confidentiality agreement and subject to customary carve outs, neither Boston Scientific nor BTG shall employ or seek to employ certain employees of the other.

Co-operation Agreement

Boston Scientific, Bravo Bidco and BTG have entered into the Co-operation Agreement pursuant to which:

· Boston Scientific and Bravo Bidco have each agreed to use commercially reasonable efforts to secure certain regulatory clearances and to satisfy certain regulatory conditions as promptly as possible following the date of the Co-operation Agreement and, in any event, by the Long Stop Date. Commercially reasonable efforts: (a) shall include divestiture of either the Boston Scientific Bead Business or the BTG Bead Business, provided that Boston Scientific has up to three months following Boston Scientific submitting a filing pursuant to the HSR Act to make the case to the US Federal Trade Commission or US Department of Justice prior to offering such divestiture; and (b) shall preclude Boston Scientific or Bravo Bidco from committing to effect any transaction that would be reasonably likely to preclude or materially impede or prejudice the effectiveness of any application for any such regulatory clearance;

· Boston Scientific, Bravo Bidco and BTG have each undertaken to, among other things, provide information and assistance in relation to filings, notifications or submissions to be made in connection with implementing the Acquisition and obtaining certain regulatory clearances; and

· Boston Scientific and Bravo Bidco have each undertaken to provide information and assistance in connection with the preparation of the Scheme Document and implementation of the Scheme.

The Co-operation Agreement records Bravo Bidco's and BTG's intention to implement the Acquisition by way of a Scheme, subject to the ability of Bravo Bidco to implement the Acquisition by way of a Takeover Offer in the circumstances described in the Co-operation Agreement. The parties have agreed that where BTG consents to Bravo Bidco implementing the Acquisition by way of a Takeover Offer, the acceptance condition to the Takeover Offer shall be set at not more than 75 per cent. of the BTG Shares to which the Takeover Offer Relates. The Co-operation Agreement contains provisions in relation to the BTG Share Schemes and to the treatment of employees as summarised in Section 10 above.

The Co-operation Agreement will terminate if:

· agreed in writing between Boston Scientific, Bravo Bidco and BTG;

· upon service of written notice from Bravo Bidco to BTG if: (a) the Scheme Document does not contain the BTG Recommendation; (b) the BTG Board withdraws or adversely modifies or qualifies the BTG Recommendation; (c) BTG makes an announcement before publication of the Scheme Document that it will not convene the Court Meeting or the General Meeting or that it intends not to post the Scheme Document (otherwise than as a result of the Acquisition being implemented by way of a Takeover Offer); or (d) a competing transaction is announced and such competing transaction is recommended by the BTG Board;

· upon service of written notice from Bravo Bidco to BTG or BTG to Bravo Bidco, the Effective Date has not occurred on or prior to the Long Stop Date; or

· a competing transaction completes, becomes effective or unconditional in all respects; or

· any Condition has been invoked, with the consent of the Panel, and the Scheme has been withdrawn, or if the Acquisition is to be implemented by way of a Takeover Offer, the Takeover Offer lapses.

16. Delisting and cancellation of trading and re-registration

It is intended that dealings in BTG Shares will be suspended shortly before the Effective Date at a time to be set out in the Scheme Document. It is further intended that applications will be made to: (a) the London Stock Exchange to cancel trading in BTG Shares on the London Stock Exchange's main market for listed securities; and (b) the UK Listing Authority to cancel the listing of the BTG Shares on the Daily Official List, in each case with effect from or shortly after the Effective Date.

The last day of dealing in BTG Shares on the London Stock Exchange is currently expected to be the Business Day immediately prior to the Effective Date and it is currently intended that no transfers will be registered after 6:00 pm on that date.

Share certificates in respect of the BTG Shares will cease to be valid and should be destroyed on the Effective Date. In addition, entitlements held within CREST to BTG Shares will be cancelled on the Effective Date.

It is Bravo Bidco's intention that in due course, following a delisting, BTG will be re-registered as a private limited company.

17. Overseas shareholders

The distribution of this Announcement to persons not resident in the United Kingdom and/or the ability of such persons to vote on the Acquisition at the BTG Meetings (or, if the Acquisition is implemented by way of a Takeover Offer, to accept such Takeover Offer) may be prohibited or affected by the laws of the relevant jurisdictions in which such persons are resident. Such persons should inform themselves about, and observe, any applicable requirements.

Further details in relation to overseas BTG Shareholders will be contained in the Scheme Document. BTG Shareholders who are in any doubt about such matters should consult an appropriate independent professional adviser in the relevant jurisdiction without delay.

18. BTG ADRs

The BTG Shares underlying the BTG ADRs will be included in the Acquisition. BTG ADR holders should contact the depositary for their BTG ADRs for information regarding their rights.

19. Documents on display

The following documents will be published on Boston Scientific's website (http://investors.bostonscientific.com/) and BTG's website (www.btgplc.com) by no later than 12 noon on the Business Day following the date of this Announcement until the end of the Offer Period:

· this Announcement;

· the irrevocable undertakings described in paragraphs 5 and 6 above;

· certain financing documents referred to in paragraph 11 above;

· the confidentiality agreement described in paragraph 15 above; and

· the co-operation agreement described in paragraph 15 above.

20. Right to Switch to a Takeover Offer

Bravo Bidco reserves the right, subject to the prior consent of the Panel and to the terms of the Co-operation Agreement, to implement the Acquisition by way of a Takeover Offer for the entire issued and to be issued share capital of BTG as an alternative to the Scheme. In such an event, a Takeover Offer will be implemented on the same terms and conditions as those which would apply to the Scheme, subject to appropriate amendments, including, save as otherwise set out in the Co-operation Agreement, an Approval Condition set at 90 per cent. in nominal value and of the voting rights attaching to such shares of the shares to which the Takeover Offer relates or such lesser percentage as Bravo Bidco may determine (subject to the consent of the Panel, if necessary), being in any case more than 50 per cent. of the voting rights normally exercisable at a general meeting of BTG, including for this purpose, any such voting rights attaching to BTG Shares that are unconditionally allotted or issued before the Takeover Offer becomes or is declared unconditional as to acceptances, whether pursuant to the exercise of any outstanding subscription or conversion rights or otherwise.

If the Acquisition is effected by way of a Takeover Offer, there can be no certainty as to the level of the Approval Condition, or of Bravo Bidco's willingness to waive or lower such Approval Condition. If such Takeover Offer becomes or is declared unconditional in all respects, where:

· acceptances are received from BTG Shareholders such that, together with any other BTG Shares unconditionally acquired, owned or controlled by Bravo Bidco and/or Boston Scientific will hold at least 75 per cent. of the voting rights attaching to the BTG Shares, Bravo Bidco intends to request that the then appointed BTG Board (subject to its fiduciary duties) will apply to the London Stock Exchange and the UK Listing Authority respectively to cancel trading in BTG Shares on the London Stock Exchange's main market for listed securities and cancel the listing of the BTG Shares on the Daily Official List, which cancellations would eliminate the liquidity of BTG Shares for any remaining BTG Shareholders; and

· Bravo Bidco receives acceptances under the Takeover Offer in respect of, or otherwise acquires, 90 per cent. or more of the BTG Shares to which the Takeover Offer relates by nominal value and voting rights attaching to such shares, Bravo Bidco intends to exercise its rights pursuant to sections 974 to 991 of the Companies Act to acquire compulsorily the remaining BTG Shares in respect of which the Takeover Offer has not been accepted on the same terms as the Takeover Offer.

Overseas jurisdictions

The release, publication or distribution of this Announcement in, and the availability of the Acquisition to persons who are residents, citizens or nationals of jurisdictions other than the United Kingdom may be restricted by laws and/or regulations of those jurisdictions. In particular, the ability of persons who are not resident in the United Kingdom or who are subject to the laws of another jurisdiction to vote their Scheme Shares with respect to the Scheme at the Court Meeting, or to execute and deliver Forms of Proxy appointing another to vote at the Court Meeting on their behalf, may be affected by the laws of the relevant jurisdictions in which they are located. Therefore, any persons not resident in the United Kingdom and/or who are subject to the laws and regulations of any jurisdiction other than the United Kingdom should inform themselves about, and observe, any applicable legal and regulatory requirements. Any failure to comply with the applicable requirements may constitute a violation of the laws and/or regulations of any such jurisdiction.

The Acquisition will not be made, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws of that jurisdiction and no person may vote in favour of the Acquisition by any use, means, instrumentality or form within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction. Accordingly, copies of this Announcement and any formal documentation relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in or into or from any Restricted Jurisdiction and persons receiving such documents (including custodians, nominees and trustees) must not mail or otherwise forward, distribute or send them in or into or from any Restricted Jurisdiction.

The receipt of cash pursuant to the Acquisition by BTG Shareholders may be a taxable transaction under applicable national, state and local, as well as foreign and other tax laws. Each BTG Shareholder is urged to consult their independent professional adviser regarding the tax consequences of the Acquisition applicable to him.

If the Acquisition is implemented by way of a Takeover Offer (unless otherwise permitted by applicable law and regulation), the Takeover Offer may not be made, directly or indirectly, in, into or by use of the mails or any other means of instrumentality (including, without limitation, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or any facility of a national, state or other securities exchange of any Restricted Jurisdiction and the Takeover Offer will not be capable of acceptance by any such use, means, instrumentality or facilities or from within any Restricted Jurisdiction where to do so would violate the laws of that jurisdiction and shall not be capable of acceptance by any such use, means, instrumentality or facility or from within such Restricted Jurisdiction.

This Announcement has been prepared for the purpose of complying with English law, the rules of the London Stock Exchange and the Code and the information disclosed may not be the same as that which would have been disclosed if this Announcement has been prepared in accordance with the laws of jurisdictions outside England and Wales.

Further details in relation to BTG Shareholders in overseas jurisdictions will be contained in the Scheme Document.

Notice to US Investors in BTG

The Acquisition relates to the shares of a company organised under the laws of England and Wales and is proposed to be effected by means of a scheme of arrangement under the laws of England and Wales (Part 26 of the Companies Act). This Announcement, the Scheme Document and certain other documents relating to the Acquisition have been or will be prepared in accordance with English law, the Code and UK disclosure requirements, format and style, all of which differ from those in the United States. A transaction effected by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the US Securities Exchange Act of 1934, as amended (the "US Exchange Act"). Accordingly, the Acquisition is subject to the disclosure requirements of and practices applicable in the United Kingdom to schemes of arrangement involving a target company in England listed on the London Stock Exchange, which differ from the disclosure requirements of the United States tender offer and proxy solicitation rules. Bravo Bidco reserves the right, subject to the prior consent of the Panel, to elect to implement the Acquisition by way of a Takeover Offer. If, in the future, Bravo Bidco exercises its right to implement the Acquisition by way of a Takeover Offer and determines to extend the Takeover Offer into the United States, such offer and the Acquisition will be made in compliance with applicable US tender offer regulations.

If the Acquisition is implemented by way of a Takeover Offer, pursuant to Rule 14e-5(b) under the US Exchange Act, Bravo Bidco, certain affiliated companies or their nominees or brokers (acting as agents) may from time to time make certain purchases of, or arrangements to purchase, shares in BTG outside such a Takeover Offer during the period in which such a Takeover Offer would remain open for acceptance. If such purchases or arrangements to purchase were to be made, they would be made outside the US and would apply in accordance with applicable law, including the US Exchange Act and the Code. Such purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases will be disclosed as required in the United Kingdom, will be reported to the Regulatory News Service of the London Stock Exchange and will be available on the London Stock Exchange website at: http://www.londonstockexchange.com/prices-and-news/prices-news/home.htm.

BTG's financial statements, and all financial information that is included in this Announcement or that may be included in the Scheme Document, or any other documents relating to the Acquisition, have been or will be prepared in accordance with non-US accounting standards that may not be comparable to financial information of companies in the United States or other companies whose financial statements are prepared in accordance with US generally accepted accounting principles.

Neither the United States Securities and Exchange Commission nor any US state securities commission has approved or disapproved the Acquisition, passed upon the merits or fairness of the Acquisition or passed any opinion upon the accuracy, adequacy or completeness of this Announcement or the Scheme Document. Any representation to the contrary is a criminal offence in the United States.

BTG is incorporated under the laws of England and Wales. In addition, some of its officers and directors reside outside the United States, and some or all of its assets are or may be located in jurisdictions outside the United States. Therefore, investors may have difficulty effecting service of process within the United States upon those persons or recovering against BTG or its officers or directors on judgments of United States courts, including judgments based upon the civil liability provisions of the United States federal securities laws. It may not be possible to sue BTG or its officers or directors in a non-U.S. court for violations of the U.S. securities laws.

The receipt of cash pursuant to the Acquisition by US holders of BTG Shares as consideration for the transfer of its Scheme Shares pursuant to the Scheme may be a taxable transaction for US federal income tax purposes and under applicable US state and local, as well as foreign and other, tax laws. Each US holder of BTG Shares is urged to consult his or her independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to him or her.

Forward Looking Statements

This Announcement contains certain statements which are, or may be deemed to be, "forward-looking statements" which are prospective in nature. All statements other than statements of current or historical fact, are or may be deemed to be, forward-looking statements. Forward-looking statements are based on current expectations and projections about future events and are therefore subject to known and unknown risks and uncertainties which could cause actual results, performance or events to differ materially from the future results, performance or events expressed or implied by the forward-looking statements. Often, but not always, forward-looking statements can be identified by the use of forward-looking words such as "plans", "expects", "is expected", "is subject to", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", "believes", "targets", "aims", "projects", "goal", "objective", "outlook", "risks", "seeks" or words or terms of similar substance or the negative thereof, as well as variations of such words and phrases or statements that certain actions, events or results "may", "could", "should", "would", "might", "probably" or "will" be taken, occur or be achieved. Such statements are qualified in their entirety by the inherent risks and uncertainties surrounding future expectations.

Such forward-looking statements involve risks and uncertainties that could significantly affect expected results and are based on certain key assumptions. Many factors could cause actual results to differ materially from those projected or implied in any forward-looking statements. Due to such uncertainties and risks, readers are cautioned not to place undue reliance on such forward-looking statements, which speak only as of the date of this Announcement. Any forward-looking statements made in this Announcement on behalf of BTG, Bravo Bidco or Boston Scientific are made as of the date of this Announcement based on the opinions and estimates of directors of BTG, Bravo Bidco or Boston Scientific, respectively and no assurance can be given that such opinions or estimates will prove to have been correct. Each of BTG, Bravo Bidco, Boston Scientific and their respective members, directors, officers, employees, advisers and any person acting on behalf of one or more of them, expressly disclaims any intention or obligation to update or revise any forward-looking or other statements contained in this Announcement, whether as a result of new information, future events or otherwise, except as required by applicable law. Neither BTG, Bravo Bidco, Boston Scientific or their respective members, directors, officers or employees, advisers or any person acting on their behalf, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this Announcement will actually occur.

No forward-looking or other statements have been reviewed by the auditors of BTG, Bravo Bidco or Boston Scientific. All subsequent oral or written forward-looking statements attributable to BTG, Bravo Bidco or Boston Scientific of their respective members, directors, officers, advisers or employees or any person acting on their behalf are expressly qualified in their entirety by the cautionary statement above.

Rounding

Certain figures included in this Announcement have been subjected to rounding adjustments. Accordingly, figures shown for the same category presented in different tables may vary slightly and figures shown as totals in certain tables may not be an arithmetic aggregation of the figures that precede them.

No profit forecasts or estimates

Nothing in this Announcement is intended or shall be deemed to be a forecast, projection or estimate of the future financial performance of BTG, Boston Scientific or Bravo Bidco for any period and no statement in this Announcement should be interpreted to mean that cash flow from operations, earnings, or earnings per share or income of those persons (where relevant) for the current or future financial years would necessarily match or exceed the historical published cash flow from operations, earnings, earnings per share or income of those persons (as appropriate).

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1 per cent. or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the Offer Period and, if later, following the Announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3:30 pm (London time) on the 10th Business Day following the commencement of the Offer Period and, if appropriate, by no later than 3:30 pm (London time) on the 10th Business Day following the Announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1 per cent. or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror, save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 pm (London time) on the Business Day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will normally be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4). Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the Offer Period commenced and when any offeror was first identified. You should contact the Panel's Market Surveillance Unit on +44 (0)20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.
