THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION

16 JULY 2026

RECOMMENDED CASH ACQUISITION

of

GOOCH & HOUSEGO PLC

by

GREENLIGHT BIDCO LIMITED

(a newly formed company owned indirectly by Arlington Capital Partners VII, L.P.)

to be implemented by means of a scheme of arrangement

under Part 26 of the Companies Act 2006

1          Introduction

The boards of directors of Bidco and G&H are pleased to announce that they have reached agreement on the terms and conditions of a recommended cash acquisition by Bidco of the entire issued, and to be issued, ordinary share capital of G&H.

It is intended that the Acquisition will be implemented by way of a court‑sanctioned scheme of arrangement between G&H and G&H Shareholders under Part 26 of the 2006 Act (although Bidco reserves the right to effect the Acquisition by way of an Offer, subject to the consent of the Panel and the terms of the Cooperation Agreement for such time as it is continuing).

2          The Acquisition

Under the terms of the Acquisition, which will be subject to the Conditions and further terms set out in Appendix 1 to this announcement and the full terms and conditions to be set out in the Scheme Document, each G&H Shareholder (where they qualified for the Interim Dividend) will be entitled to receive a total value of:

1,234.9 pence for each G&H Share

comprising, for each G&H Share held:

·    1,230.0 pence in cash per G&H Share (the "Cash Consideration"); and

·    the interim dividend of 4.9 pence per G&H Share declared on 2 June 2026 (the "Interim Dividend"), which qualifying G&H Shareholders who were on the register of members as at the close of business on 19 June 2026 are entitled to receive and retain without any reduction to the Cash Consideration (together with the Cash Consideration, the "Total Value").

The Cash Consideration represents a premium of approximately:

·    40.7% to the Closing Price of 874.0 pence per G&H Share on 15 July 2026 (being the last Business Day before the date of this announcement);

·    34.0% to the volume-weighted average price of 918.0 pence per G&H Share for the one-month period ended 15 July 2026 (being the last Business Day before the date of this announcement); and

·    45.7% to the volume-weighted average price of 844.1 pence per G&H Share for the six-month period ended 15 July 2026 (being the last Business Day before the date of this announcement).

The Total Value represents a premium of approximately:

·    41.3% to the Closing Price of 874.0 pence per G&H Share on 15 July 2026 (being the last Business Day before the date of this announcement);

·    34.5% to the volume-weighted average price of 918.0 pence per G&H Share for the one-month period ended 15 July 2026 (being the last Business Day before the date of this announcement); and

·    46.3% to the volume-weighted average price of 844.1 pence per G&H Share for the six-month period ended 15 July 2026 (being the last Business Day before the date of this announcement).

The Cash Consideration:

·    values G&H's entire issued, and to be issued, ordinary share capital at approximately £345.6 million on a fully diluted basis; and

·    implies an enterprise value of £400.5 million and a multiple of approximately 25.9x G&H's adjusted operating profit for the twelve-month period ended 31 March 2026.

The G&H Shares will be acquired pursuant to the Acquisition fully paid and free from all liens, charges, equities, encumbrances, rights of pre‑emption and any other interests of any nature whatsoever and together with all rights attaching thereto, including without limitation voting rights and the right to receive and retain in full all dividends and other distributions or any other return of capital (whether by way of reduction of share capital or share premium account or otherwise) (if any) announced, declared, made or paid with a record date on or after the Effective Date.

If, on or after the date of this announcement and prior to the Acquisition becoming Effective, any dividend and/or other distribution and/or other return of capital or value (other than the Interim Dividend) is announced, declared, made or paid or becomes payable in respect of the G&H Shares, Bidco reserves the right to reduce the Cash Consideration payable under the terms of the Acquisition for the G&H Shares by an amount up to the aggregate amount of such dividend and/or distribution and/or other return of capital or value, in which case any reference in this announcement to the Cash Consideration payable under the terms of the Acquisition will be deemed to be a reference to the Cash Consideration as so reduced. Any exercise by Bidco of its rights referred to in this paragraph shall be the subject of an announcement and, for the avoidance of doubt, shall not be regarded as constituting any revision or variation of the terms of the Scheme or the Acquisition. In such circumstances, G&H Shareholders would be entitled to retain any such dividend, distribution and/or other return of capital or value.

3          Interim dividend

The G&H Directors have declared the Interim Dividend for the half year ended 31 March 2026. The Interim Dividend will be paid by G&H on 24 July 2026 to qualifying G&H Shareholders who were on the register of members as at the close of business on 19 June 2026, without any reduction to the Cash Consideration.

G&H Shareholders who are not entitled to receive the Interim Dividend, including G&H Shareholders who are not on the register of members of G&H at the relevant record time in respect of the Interim Dividend, shall receive the Cash Consideration only.

4          Background to and reasons for the Acquisition

As a world leading photonics engineering group, G&H is a differentiated franchise with a broad offering of mission-critical photonics and high-precision optical subsystems, increasing momentum in its aerospace & defence portfolio, and exposure to an attractive set of end-market segments, geographies, and customers.

Through its extensive track record of investing in high quality, highly engineered and mission-critical companies in the aerospace, defence, life sciences and broader regulated sectors, ACP brings highly relevant expertise in the sectors within which G&H operates. Over the past 27 years, ACP has completed over 200 transactions and currently manages 24 portfolio companies, most of which participate in G&H's end markets.

Select examples of investments made by ACP in sectors where G&H operates include:

·    the acquisition of Highwater in 2026, a leading global naval services platform preserving Allied Naval readiness across the US and Australia;

·    the acquisition of GRVTY in 2024, a defence technology company delivering leading edge solutions to address top national security priorities;

·    the acquisition of Keel in 2023, a leading manufacturer of complex structures for the highest priority programs within the US navy, army, and air force;

·    the acquisition of Exostar in 2023, a leading cloud-based secure business collaboration software provider serving highly regulated industries including aerospace and defence, healthcare and life sciences and banking, financial services and insurance;

·    the acquisition of Stellant Systems in 2021, a premier designer and manufacturer of radio frequency and microwave amplification products  serving defence, space, medical and industrial markets;

·    the formation of BlueHalo in 2019, a provider of industry-leading capabilities in the domains of Space Technologies, c-UAS, Directed Energy, Electronic Warfare, Cyber, Artificial Intelligence and other Emerging Technologies;

·    the acquisition of Forged Solutions Group in 2019, a leading provider of complex, precision forgings to aerospace, defence and space customers;

·    the acquisition of Tex-Tech Industries in 2017, a leading developer and manufacturer of proprietary, highly engineered solutions serving aerospace, space and defence, and specialty industrial end markets;

·    the acquisition of Molecular Products in 2016, a leading manufacturer of advanced chemistry-based products serving the healthcare, defence and industrial markets;

·    the acquisition of Endeavor Robotics in 2016, a leading independent provider of ground-based robotics systems for use in the most dangerous and hostile environments; and

·    the acquisition of United Flexible in 2015, a global leader in the design, development, manufacture, and support of high performance mission-critical engineered solutions for the transfer of fluids and gases in extreme environments.

ACP has long admired G&H and has been impressed by its reputation for quality, product expertise, technical performance, and innovation, underpinned by an increasing focus on R&D and capital spend to drive new product development and capacity expansion.

ACP recognises the journey the G&H management team has embarked on in positioning G&H as an innovative, customer-focused solutions provider. Bidco believes it can support G&H's management team and employee base with a view to providing attractive and sustained growth and development opportunities for G&H and its wider stakeholders.

Bidco believes that as a long-term, supportive partner to G&H, with access to additional capital and extensive industry knowledge, commercial relationships and operational expertise, Bidco can accelerate G&H's growth plans, support continued investment to fund innovation and R&D with a long-term horizon, and pursue selective M&A where strategically and financially attractive.

Bidco believes that under private ownership and with ACP's experience, capabilities and long-term-partnership approach, it would be better able to support and accelerate G&H's strategy, consistent with the approach taken with other ACP investments within the sector.

5          Recommendation

The G&H Directors, who have been so advised by Investec and Rothschild & Co as to the financial terms of the Acquisition, consider the terms of the Acquisition to be fair and reasonable. In providing their advice, Investec and Rothschild & Co have taken into account the commercial assessments of the G&H Directors. Investec and Rothschild & Co are providing independent financial advice to the G&H Directors for the purposes of Rule 3 of the Takeover Code.

Accordingly, the G&H Directors intend to recommend unanimously that G&H Shareholders vote in favour of the Scheme at the Court Meeting and the Resolutions, as the G&H Directors who hold G&H Shares have irrevocably undertaken to do in respect of their own (and where, applicable, their close relatives') beneficial holdings totalling 119,582 G&H Shares (representing approximately 0.44% of the existing issued ordinary share capital of G&H as at 15 July 2026, being the Business Day prior to the date of this announcement). These undertakings will remain binding in the event a higher competing offer is received. Further details of these undertakings, including the circumstances in which they cease to be binding, are set out in Appendix 3 to this announcement.

6          Background to and reasons for the recommendation

G&H today and its strategic plan

Since its formation in 1948, G&H has developed into a specialist designer and manufacturer of advanced photonic components and systems, serving customers across the industrial, life sciences, and aerospace & defence sectors. G&H has leading technical expertise and innovative capabilities in the photonics sector specialising in precision optics and systems, acousto-optics, electro-optics, fibre optics and modules.

In June 2023, G&H announced a refreshed strategic plan to become an innovative, customer-focused technology company and the partner of choice in photonics. Since then, G&H has made good progress executing this strategy, including through operational improvement initiatives, portfolio review actions, targeted investment, and the integration of recent acquisitions.

The Board is pleased with the progress made on implementing the strategic plan. G&H has continued to deliver strategic change to support G&H's margin expansion ambitions, with the "speed to value" acquisitions of Artemis Optical, Phoenix Optical and Global Photonics now fully integrated. G&H's order book at 31 March 2026 increased by 16.5% on a constant currency basis to £167.3 million (30 September 2025: £142.4 million). Operational and supply chain investments are delivering results: productivity improvements at the Moorpark and Ilminster precision optics sites are supporting the aerospace & defence turnaround, production output has increased, and G&H continues to invest to meet increased customer demand, address bottlenecks and ease capacity constraints. G&H is also maintaining targeted R&D investment in higher margin products over the medium term. G&H operates from 11 sites, plus from several contract manufacturing partners specialising in photonics in the UK, US and Asia.

Despite this progress, G&H continues to face global uncertainties which remain a risk to the near-term execution of G&H's strategy. Geopolitical uncertainty and supply chain disruption continue to affect the timing and scale of recovery in certain markets. The macroeconomic background remains volatile with fluid tariff policies, retaliatory measures and continued unrest in Ukraine and the Middle East. G&H's direct exposure to those countries that have been subjected to the current most significant tariff increases on imports to the US is limited but exposure to more general market instability persists with potential for order delays and inflationary impacts of increasing global tariffs. G&H has been able to re-source the supply of certain key raw materials where availability has been restricted and accordingly G&H continues to hold higher stock levels. Cost increases arising from these developments are being passed on through higher pricing where possible.

G&H has strengthened its position in germanium-related products, which are critical to a number of aerospace & defence and semiconductor applications. However, germanium prices have increased significantly both year on year and year to date. Raw material availability remains constrained and variable, and while G&H has taken steps to optimise sourcing and improve resilience, its relative scale means that such pressures are more difficult to absorb in set financial reporting periods which are publicly announced, particularly while continuing to invest in strategic growth.

The Board remains confident in G&H's ability to drive further profitable growth, supported by its differentiated photonics expertise, the long-term growth in aerospace & defence, recovery in the semiconductor market, and alignment to structurally attractive end markets.

Considerations in respect of ACP's Offer

The Board did not solicit an offer for G&H, although it regularly evaluates opportunities to maximise shareholder value.

ACP made a series of unsolicited proposals to the Board, all of which were carefully considered and rejected on the basis that they did not appropriately reflect the value of G&H and its future prospects. Following a subsequent proposal at 1,230.0 pence per share, ACP was granted access to certain information on G&H and a small number of the management team in order to undertake due diligence and progress discussions.

While the Board remains confident in its ability to deliver sustainable value for shareholders, the Board recognises that the Acquisition provides G&H Shareholders with immediate and certain value in cash at a significant premium to both the share price on the day prior to this announcement and to trading levels over the past three years, while also recognising the value of G&H's strategy, market positions and long-term growth prospects. The Cash Consideration represents fair value when compared to average selected precedent sector transaction multiples. The Board believes the Cash Consideration reflects today's value in cash of G&H's internal long-term future cashflows discounted at an appropriate weighted average cost of capital.

Based on the Cash Consideration of 1,230.0 pence per G&H Share and the twelve-month period ended 31 March 2026, the Cash Consideration represents a historic EV / Adjusted operating profit of 25.9x and a historic Price / Adjusted Earnings of 35.4x versus G&H's historic EV / Adjusted operating profit of 19.4x and a historic Price / Adjusted Earnings of 25.2x based on the Closing Price of 874.0 pence on 15 July 2026 (being the last Business Day before the date of this announcement) and the twelve-month period ended 31 March 2026.

Although the Board remains confident in G&H's medium-term prospects and its ability to capitalise on the structural growth drivers in its end-markets, delivering the full benefits of G&H's strategy would require continued execution and improvement and remains subject to a number of risks, including customer programme timing, supply-chain constraints, broader macroeconomic conditions and the pace of recovery in certain end markets. The Board has also considered G&H's position as a smaller AIM-listed company, the liquidity in its shares and the broader UK small and mid-cap market backdrop.

The Board also recognises that, under private ownership, G&H may be better placed to accelerate the execution of its strategy by investing materially more capital, at a faster rate, behind growth opportunities. This may include pursuing selective M&A, which may result in significantly higher short-term debt and assessing operational initiatives across its specialist sites and end-markets with greater flexibility than would be available to it as a smaller, AIM-listed company.

The Board is also mindful that G&H operates at a smaller scale than certain of its competitors, at a time when a number of the end-markets in which it operates are continuing to consolidate. In that context, the Board believes that G&H's US business is of particular strategic importance, given the increasing relevance of local manufacturing, supply-chain resilience and customer proximity in a more localising and de-globalising environment.

The Board also recognises the importance of continuing to attract and retain high-quality management and specialist technical talent in competitive international markets. As a UK-listed company of G&H's size, G&H faces constraints in ensuring that its remuneration arrangements remain competitive with larger international and private-company peers. The Board has also taken into account recent shareholder feedback on remuneration.

In evaluating ACP as a long-term partner for G&H, the Board has taken into account ACP's experience investing in technically complex, highly regulated and mission-critical end markets, including aerospace & defence, life sciences and other specialist industrial technology sectors. The Board believes this experience is relevant to G&H's customer base, qualification requirements, programme cycles and supply-chain complexity. ACP has demonstrated an appreciation of G&H's technical capabilities and strategic opportunities, including the potential to accelerate investment in operational capability and innovation and support selective M&A in adjacent specialist technology markets. The Board has noted ACP's stated intentions regarding the future of the business, including its support for G&H's strategy and growth ambitions, and believes that ACP's ownership would provide G&H with access to capital and strategic flexibility to support the next phase of its development. In considering the Offer, the Board has taken into account ACP's stated intentions for all its stakeholders, including its employees, customers, and broader network of stakeholders.

Accordingly, having taken into account all the above factors, and having been so advised by Investec Bank plc and Rothschild & Co as to the financial terms of the Offer, the G&H Directors consider the terms of the Offer to be fair and reasonable. In providing their advice, Investec Bank plc and Rothschild & Co have taken into account the commercial assessments of the G&H Directors. Investec Bank plc and Rothschild & Co are providing independent financial advice to the G&H Directors for the purposes of Rule 3 of the Takeover Code.

The G&H Directors therefore intend to recommend unanimously that G&H Shareholders vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the General Meeting, as the G&H Directors who hold G&H Shares have irrevocably undertaken to do in respect of their own (and where, applicable, their close relatives') beneficial holdings.

8          Information relating to G&H

G&H is a specialist designer and manufacturer of advanced photonic components and systems, serving customers across the aerospace & defence, industrial and life sciences markets. G&H has leading technical expertise and innovative capabilities in the photonics sector, specialising in precision optics and optical systems, acousto- and electro-optics, fibre optics and thin film coatings.

Headquartered in Ilminster, Somerset, United Kingdom, G&H operates from 11 manufacturing sites, supported by several contract manufacturing partners specialising in photonics in the UK, US and Asia. G&H also maintains a commercial presence across Continental Europe and the wider Asia Pacific.

·    G&H serves three principal end markets:

o Aerospace & Defence: delivering mission-critical optics and optical systems used in land, air and sea applications, including, among others, imaging and sighting systems, AFV periscopes, directed-energy applications, countermeasures, space laser communications and super-polished components for ring-laser gyroscopes used in navigation. For the year ended 30 September 2025, the segment generated revenue of £52.4 million.

o Industrial: supplying acousto-optic and electro-optic components and systems for industrial lasers, microelectronics processing and advanced photolithography, as well as precision and fibre-optic solutions used in semiconductor, telecommunications, sensing and subsea applications. For the year ended 30 September 2025, the segment generated revenue of £64.3 million.

o Life Sciences: designing and manufacturing optical components and lens assemblies for medical devices and providing subsystem and full system solutions for medical diagnostic instruments. G&H offers full product development, regulatory compliance, certified manufacturing and after-sales service. For the year ended 30 September 2025, the segment generated revenue of £33.7 million.

For the year ended 30 September 2025, G&H reported revenue of £150.5 million and adjusted profit before tax of £11.9 million, with an order book of £142.4 million and order intake of £178.6 million. Net debt at year end was £43.9 million (£29.9 million excluding lease liabilities).

G&H's expanding order book and robust demand in aerospace & defence provide good visibility through the remainder of FY26 and into the medium term. In H1 2026, revenue increased by 15.5% to £81.9 million (H1 2025: £70.9 million), and adjusted operating profit increased by 16.9% to £7.2 million (H1 2025: £6.2 million), with adjusted operating margin improving slightly to 8.8%. Net debt to EBITDA leverage increased from 1.3x to 1.5x. G&H's order book increased by 16.5% on a constant currency basis to £167.3 million (September 2025: £142.4 million). Whilst G&H's FY26 trading performance was already expected to be weighted towards the second half of the financial year, the Board now expects this weighting to be more pronounced in Q4 FY26, reflecting the impact of supply chain constraints on the anticipated timing of order book conversion and programme deliveries.

Aerospace & defence revenue increased by 51.7% to £35.6 million in H1 2026, with margin improving to 10.2%. Industrial revenue remained flat at £30.3 million, with adjusted operating margin increasing slightly to 12.7%; order intake improved, supported by the recovery in semiconductor-related end markets, including processing, sensing and advanced microelectronics. Life sciences revenue decreased 7.7% to £16.0 million, with adjusted operating margin declining to 4.6%.

M&A is a core component of G&H's strategy. Recent strategic actions include the "speed-to-value" acquisitions of GS Optics (June 2023), Artemis Optical (July 2023), Phoenix Optical (October 2024) and US-based Global Photonics (June 2025), which strengthened G&H's precision optics, optical systems and thin film coating capabilities and expanded its North American platform. Integration of these businesses is largely complete, particularly supporting new defence orders from customers in the US, UK and Europe. G&H also completed the divestment of EM4 in March 2024. G&H continues to assess further opportunities for M&A.

As at 15 July 2026, being the last Business Day prior to the date of this announcement, G&H's fully diluted market capitalisation was £245.6 million. G&H's shares are admitted to trading on AIM under the ticker GHH. For more information, visit www.gandh.com.

Clean Team Agreement

On 8 June 2026, ACP, on behalf of Bidco, and G&H entered into a Clean Team Agreement which sets out, among other things, how any confidential information that is competitively sensitive can be disclosed, used or shared between ACP's clean team individuals and/or external advisers and G&H's clean team individuals and/or external advisers.

Cooperation Agreement

Pursuant to the Cooperation Agreement, Bidco and G&H have, amongst other things, each agreed to: (i) cooperate in relation to obtaining any consents, clearances, permissions, waivers and/or approvals as may be necessary, and the making of all filings as may be necessary, from or under the law, regulations or practices applied by any applicable regulatory authority in connection with the Acquisition; and (ii) cooperate in preparing and implementing appropriate proposals in accordance with Rule 15 of the Takeover Code in relation to the G&H Share Plan. In addition, Bidco has agreed to certain provisions if the Scheme should switch to an Offer. The Cooperation Agreement may terminate in certain circumstances, including if the Acquisition is withdrawn, terminated or lapses, a third party announces a firm intention to make an offer for G&H which completes, becomes effective or becomes unconditional, if prior to the Long Stop Date any Condition has become incapable of satisfaction and has been invoked by Bidco (with the consent of the Panel), if the G&H Directors withdraw their recommendation of the Acquisition or if the Scheme does not become Effective in accordance with its terms by the Long Stop Date or otherwise as agreed between Bidco and G&H. Pursuant to the terms of the Cooperation Agreement and the requirements of Paragraph 3(g)(i) of Appendix 7 to the Takeover Code, Bidco undertakes that it will deliver a notice in writing to G&H on the Business Day prior to the Sanction Hearing confirming either: (i) the satisfaction or waiver of the Conditions (other than certain of the Scheme Conditions, as defined therein); or (ii) subject to obtaining the consent of the Panel, that it intends to invoke or treat as unsatisfied or incapable of satisfaction one or more Conditions.

12        Disclosure of interests in G&H securities

Except for the irrevocable undertakings referred to in paragraph 9 above and Appendix 3, as at 15 July 2026 (being the last practicable date prior to the date of this announcement) neither Bidco, nor any of its directors, nor, so far as Bidco is aware, any person treated as acting in concert (within the meaning of the Takeover Code) with it for the purposes of the Acquisition: (i) had any interest in or right to subscribe for or had borrowed or lent any G&H Shares or securities convertible or exchangeable into G&H Shares; or (ii) had any short positions in respect of relevant securities of G&H (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; or (iii) has borrowed or lent any relevant securities of G&H (including, for these purposes, any financial collateral arrangements of the kind referred to in Note 3 on Rule 4.6 of the Takeover Code) save for any borrowed shares which have been either on-lent or resold; or (iv) is a party to any dealing arrangement of the kind referred to in Note 11(a) on the definition of acting in concert in the Takeover Code.

It has not been practicable for Bidco to make enquiries of all of its concert parties in advance of the release of this announcement. Therefore, if Bidco becomes aware, following the making of such enquiries, that any of its concert parties have any additional interests in the relevant securities of G&H, all relevant details in respect of Bidco's concert parties will be included in Bidco's Opening Position Disclosure (if any) in accordance with Rule 8.1(a) and Note 2(a)(i) on Rule 8 of the Takeover Code which must be made on or before 12 noon (London time) on 30 July 2026.

'Interests in securities' for these purposes arise, in summary, when a person has long economic exposure, whether absolute or conditional, to changes in the price of securities (and a person who only has a short position in securities is not treated as interested in those securities). In particular, a person will be treated as having an 'interest' by virtue of the ownership, voting rights or control of securities, or by virtue of any agreement to purchase, option in respect of, or derivative referenced to securities.

Strategic plans for G&H

Bidco believes that G&H is a highly attractive, differentiated business franchise with a broad offering of mission-critical photonics and high-precision optical subsystems, which benefits from an established position in the global photonics industry, increasing momentum in its aerospace & defence portfolio, and exposure to an attractive set of end-market segments, geographies, and customers.

Bidco is supportive of G&H's strategy and desire to scale its business, and in particular its existing and disciplined M&A strategy, expansion of its aerospace & defence end market exposure and preserving a culture in line with G&H's Value and Behaviours guide that continues to attract and retain top-tier industry talent. Bidco believes that the successful execution of these strategies and any further strategies identified in the Evaluation referred to below can be underpinned and enhanced without the pressures of being a listed business, and private ownership allows access to additional capital and industry expertise to accelerate the longer-term growth of the business. Bidco also understands G&H's important role as trusted supplier to defence programmes critical to the UK, US and their allies. Consistent with ACP's track record as an experienced investor in aerospace and defence, ACP is committed to being a responsible steward of G&H.

In line with market practice for a transaction of this nature, Bidco was granted access to G&H's senior management for the purposes of confirmatory due diligence.

Following the Scheme becoming Effective, Bidco intends to conduct, together with the G&H management team, a detailed evaluation of the business, operations, and organisational structure of G&H to determine investment and growth priorities. Bidco intends that this evaluation will be completed within approximately 6 months of the Effective Date, and will focus on:

·    a detailed review of G&H's existing business lines and growth opportunities;

·    consistent with G&H's existing strategy of making strategic acquisitions, identifying acquisition opportunities to accelerate the growth of the business and create other inorganic benefits;

·    engaging with G&H's key stakeholders, including employees, customers, suppliers and communities;

·    identifying opportunities to augment G&H's existing R&D and capital expenditure strategy to drive long-term growth;

·    considering operational improvement opportunities across the global supply chain and manufacturing footprint; and

·    through site visits, planning sessions and collaborative problem solving, identifying ways to improve profitability,

(the "Evaluation").

Bidco is aware of G&H's existing publicly announced plans to exit from the medical laser Pockels Cells manufacturing business line, operated out of its facility in Cleveland, Ohio, and understands that G&H has reduced its R&D focus in that business line accordingly. Bidco will continue to assess the implementation of the exit from the medical laser Pockels Cells manufacturing business line as part of its Evaluation.

Bidco attaches great importance to the skill and experience of G&H's management and employees and recognises that the employees and management of G&H have been and will continue to be key to the continued success of G&H.

As part of the Evaluation and G&H's transition to private ownership, Bidco intends to undertake a customary assessment of areas where any change in the overall composition of functions is required. Prior to the conclusion of the Evaluation, separate from any existing headcount reductions proposed by G&H in connection with the exit from the manufacture of medical laser Pockels Cells, it is intended that there will be headcount reductions in public company-related and back-office functions which will no longer be required.

Independent from the reductions referred to above, following the conclusion of the Evaluation, and depending on its outcome, it is possible that a decision may be taken to implement certain headcount reductions. However, Bidco does not intend to make any material reductions to the headcount of the G&H Group.

The detailed steps for any headcount reductions are subject to the Evaluation and, if implemented, would also be subject to comprehensive and detailed planning, appropriate engagement and consultation with representatives and other stakeholders, including affected employees and any appropriate employee representative bodies in accordance with Bidco's legal obligations.

Where any roles are reduced, any individuals impacted will be treated in a manner consistent with applicable law and G&H's usual policies and practices (including where relevant, informing and consulting obligations).

It is expected that each of the non-executive directors of G&H will resign as directors of G&H with effect from the Scheme becoming Effective and the committees of the G&H Board will be disbanded.

Save as described above, Bidco does not intend for there to be any material changes to the conditions of employment or the balance of skills and functions of employees and management of G&H.

Existing employment rights and pensions

G&H has confirmed to Bidco that the only pension scheme it currently makes available to its employees is a defined contribution pension scheme and it does not have any current or historical obligations towards any pension arrangements providing benefits on a defined benefit basis.

Bidco confirms that it does not intend to make any material change to the defined contribution pension arrangements operated by G&H (including with regard to the employer contributions, the accrual of benefits for existing members and the admission of new members).

Bidco intends to fully safeguard the existing contractual and statutory employment rights, including in relation to pensions, of all G&H management and employees in accordance with applicable law.

Management incentive arrangements

Following the Acquisition becoming Effective, Bidco intends to review the management, governance and incentive structure of G&H. Bidco has not entered into, and has not had discussions on proposals to enter into, any form of incentivisation arrangements with members of G&H's management, but may have discussions and enter into such arrangements for certain members of the G&H management team following the Effective Date.

Headquarters, locations, fixed assets and research and development

Bidco understands the importance of R&D to G&H and its businesses and has no intentions to reduce G&H's investment in R&D functions or to make any material changes to the nature of those functions, in each case, subject to the outcome of the Evaluation (which will include reviewing opportunities to expand facilities and/or re-allocate manufacturing as between facilities, as appropriate). Bidco notes that G&H has publicly announced plans (in the 2025 G&H Annual Report) in relation to a pipeline of products that are to be transferred for manufacturing to G&H's manufacturing partners. Bidco intends to review this strategy as part of its Evaluation.

Bidco intends that G&H will continue to operate as a standalone business group. Currently, G&H generates a significant proportion of its revenue from each of the US and Europe (and in particular, the UK). Bidco intends to implement a reorganisation of G&H's corporate entities to move the US entities into a subgroup that is fully owned by US legal entities but still under the control of Bidco or its holding companies. This change is not anticipated to change how the legal entities are operationally managed by G&H's leadership. Such group reorganisation would take place shortly following the Effective Date and would not impact employee headcount or the functions of G&H employees.

Bidco has no intentions to undertake any other material restructurings or changes in, and does not intend for the geographical split of the business described to have any effect on, the locations of G&H's fixed assets or places of business.

Bidco has no plans to change the location or functions of G&H's headquarters in Ilminster, other than in respect of the listed company-related functions as described above.

Sustainability

Bidco supports G&H's existing commitments to reduce its environmental impact. Bidco intends to continue the focus of making G&H a sustainable business.

Trading Facilities

The G&H Shares are currently listed on AIM and, as set out in paragraph 16 below, prior to the Scheme becoming Effective, an application will be made by G&H for the cancellation of trading of the G&H Shares on AIM to take effect shortly after the Effective Date. The last day of dealings in G&H Shares is expected to be the Business Day immediately prior to the Effective Date and no transfers shall be registered after 6.00 p.m. on that date. On the Effective Date, share certificates in respect of G&H Shares shall cease to be valid and entitlements to G&H Shares held within the CREST system shall be cancelled. It is also proposed that, following the Effective Date and after its shares are de-listed, G&H shall be re-registered as a private limited company. Please refer to paragraph 16 of this announcement for further information.

None of the statements in this paragraph 13 are "post-offer undertakings" for the purposes of Rule 19.5 of the Takeover Code.

14        G&H SHARE PLAN

Participants in the G&H Share Plan, will be contacted regarding the effect of the Acquisition on their rights under the G&H Share Plan. Appropriate proposals will be made to such participants in accordance with Rule 15 of the Takeover Code in due course. Further details of those proposals and the impact of the Scheme on awards under the G&H Share Plan will be set out in the Scheme Document and in separate communications to be sent to participants in the G&H Share Plan.

15        Scheme process

It is intended that the Acquisition will be implemented by means of a court-sanctioned scheme of arrangement between G&H and G&H Shareholders under Part 26 of the 2006 Act, although Bidco reserves the right to implement the Acquisition by means of an Offer (subject to Panel consent and the terms of the Cooperation Agreement for such time as it is continuing). The purpose of the Scheme is to provide for Bidco to become the owner of the entire issued and to be issued ordinary share capital of G&H. The Scheme is an arrangement between G&H and holders of Scheme Shares and is subject to the approval of the Court. Under the Scheme, the Acquisition is to be achieved by the transfer of the Scheme Shares to Bidco in consideration for which holders of Scheme Shares will receive the Cash Consideration on the basis set out in paragraph 2 of this announcement. The procedure involves, among other things, an application by G&H to the Court to sanction the Scheme.

The Acquisition is subject to the Conditions and certain further terms referred to in Appendix 1 to this announcement and to the full terms and conditions to be set out in the Scheme Document, and will only become Effective if, among other things, the following events occur on or before the Long Stop Date:

·    a resolution to approve the Scheme is passed by a majority in number of G&H Shareholders present and voting (and entitled to vote) at the Court Meeting, either in person or by proxy, representing 75% or more in value of each class of the Scheme Shares held by those G&H Shareholders;

·    the resolution(s) necessary to implement the Scheme and the Acquisition is/are passed by the requisite majority of G&H Shareholders at the General Meeting;

·    following the Court Meeting and General Meeting and satisfaction and/or waiver (where applicable) of the other Conditions, the Scheme is sanctioned by the Court (without modification, or with modification on terms agreed by Bidco and G&H); and

·    following such sanction, a copy of the Court Order is delivered to the Registrar of Companies.

The Conditions in paragraphs 1 and 2 of Appendix 1 to this announcement provide that the Scheme will lapse (under the authority of Rule 13.5(b) of the Takeover Code) if:

·    the Court Meeting and the General Meeting are not held by the 22nd day after the expected date of the Court Meeting and the General Meeting to be set out in the Scheme Document in due course (or such later date as: (i) may be agreed between Bidco and G&H; or (ii) (in a competitive situation) as may be specified by Bidco with the consent of the Panel, and in each case that, if so required, the Court may allow);

·    the Sanction Hearing to approve the Scheme is not held by the 22nd day after the expected date of the Sanction Hearing to be set out in the Scheme Document in due course (or such later date as: (i) may be agreed between Bidco and G&H; or (ii) (in a competitive situation) as may be specified by Bidco with the consent of the Panel, and in each case that, if so required, the Court may allow); or

·    the Scheme does not become Effective by 11.59 p.m. on the Long Stop Date.

If any Condition in paragraph 2 of Part A of Appendix 1 to this announcement is not capable of being satisfied by the date specified therein, Bidco shall make an announcement through a Regulatory Information Service as soon as practicable and, in any event, by not later than 8.00 a.m. on the Business Day following the date so specified, stating whether Bidco has invoked that Condition, (where applicable) waived that Condition or, with the agreement of G&H, specified a new date by which that Condition must be satisfied.

Once the necessary approvals from G&H Shareholders have been obtained and the other Conditions have been satisfied or (where applicable) waived and the Scheme has been approved by the Court, the Scheme will become Effective upon delivery of a copy of the Court Order to the Registrar of Companies. Subject to the satisfaction of the Conditions, the Scheme is expected to become Effective during the fourth quarter of 2026.

Upon the Scheme becoming Effective: (i) it will be binding on all G&H Shareholders, irrespective of whether or not they attended or voted at the Court Meeting or the General Meeting (and if they attended and voted, whether or not they voted in favour); and (ii) share certificates in respect of G&H Shares will cease to be valid and entitlements to G&H Shares held within the CREST system will be cancelled. In accordance with the applicable provisions of the Takeover Code, the Cash Consideration for the transfer of the Scheme Shares to Bidco will be despatched no later than 14 days after the Effective Date.

Any G&H Shares issued before the Scheme Record Time will be subject to the terms of the Scheme. The resolution(s) to be proposed at the General Meeting will, amongst other matters, provide that the Articles be amended to incorporate provisions requiring any G&H Shares issued or transferred after the Scheme Record Time (other than to Bidco and/or its nominees) to be automatically transferred to Bidco on the same terms as the Acquisition (other than terms as to timings and formalities). The provisions of the Articles (as amended) will avoid any person (other than Bidco and their nominees) holding shares in the capital of G&H after the Effective Date.

Further details of the Scheme, including expected times and dates for each of the Court Meeting, the General Meeting and the Sanction Hearing, together with notices of the Court Meeting and the General Meeting, will be set out in the Scheme Document. It is expected that the Scheme Document and the Forms of Proxy accompanying the Scheme Document will be published as soon as practicable and in any event within 28 days of this announcement (or such later date as Bidco and G&H may, with the consent of the Panel, agree and, if required, the Court may approve).

16        Delisting, and cancellation of trading and  re‑registration

It is intended that dealings in G&H Shares should be suspended shortly prior to the Effective Date, at a time to be set out in the Scheme Document. It is intended that the London Stock Exchange will be requested to cancel trading of G&H Shares on AIM shortly after the Effective Date.

It is expected that the last day of dealings in G&H Shares on AIM will be the Business Day immediately prior to the Effective Date and no transfers will be registered after 6.00 p.m. (London time) on that date.

It is intended that G&H will be re-registered as a private limited company and for this to take effect as soon as practicable following the Effective Date.

18        General

Bidco reserves the right to elect (with the consent of the Panel and subject to the terms of the Cooperation Agreement for such time as it is continuing) to implement the acquisition of the G&H Shares by way of an Offer as an alternative to the Scheme. In such event, the Offer will be implemented on the same terms, so far as is applicable, as those which would apply to the Scheme (subject to appropriate amendments, including (without limitation and for so long as the Cooperation Agreement is continuing) an acceptance condition set at 90% of the G&H Shares (or such lower percentage as may be determined by Bidco after (to the extent necessary) consultation with the Panel, being in any case more than 50% of the voting rights attaching to the G&H Shares)).

If the Acquisition is effected by way of an Offer, and such an Offer becomes or is declared unconditional and sufficient acceptances are received, Bidco intends to: (i) make a request to the London Stock Exchange to cancel the trading of G&H Shares on AIM; and (ii) exercise its rights to apply the provisions of Chapter 3 of Part 28 of the 2006 Act so as to acquire compulsorily the remaining G&H Shares in respect of which the Offer has not been accepted.

Investors should be aware that Bidco may purchase G&H Shares otherwise than under the Scheme or any Offer, including pursuant to privately negotiated purchases.

The Acquisition will be on the terms and subject to the conditions set out herein and in Appendix 1, and to be set out in the Scheme Document. The bases and sources for certain financial information contained in this announcement are set out in Appendix 2. Details of undertakings received by Bidco are set out in Appendix 3. Certain definitions and terms used in this announcement are set out in Appendix 4. The formal Scheme Document will be sent to G&H Shareholders within 28 days of this announcement (or on such later date as may be agreed with G&H and the Panel).

In deciding whether or not to vote or procure votes in favour of the Scheme at the Court Meeting or to vote or procure votes in favour of the Resolutions at the General Meeting, G&H Shareholders should rely on the information contained, and follow the procedures described, in the Scheme Document.

Overseas Shareholders

The release, publication or distribution of this announcement in or into jurisdictions other than the UK may be restricted by law and therefore any persons who are subject to the law of any jurisdiction other than the UK should inform themselves of, and observe, any applicable legal or regulatory requirements. Any failure to comply with such requirements may constitute a violation of the securities laws or regulations of any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person. This announcement has been prepared in accordance with and for the purpose of complying with English law, the Takeover Code, the AIM Rules, the Market Abuse Regulation and the Disclosure Guidance and Transparency Rules and information disclosed may not be the same as that which would have been prepared in accordance with the laws or regulations of jurisdictions outside England.

The availability of the Acquisition to G&H Shareholders who are not resident in and citizens of the UK may be affected by the laws or regulations of the relevant jurisdictions in which they are located or of which they are citizens. Persons who are not resident in the UK or who are subject to the laws of any jurisdiction other than the UK (including Restricted Jurisdictions) should inform themselves of, and observe, any applicable legal or regulatory requirements of their jurisdictions. In particular, the ability of persons who are not resident in the United Kingdom to participate in the Acquisition or to vote their G&H Shares with respect to the Scheme at the Court Meeting, or to appoint another person as proxy to vote at the Court Meeting on their behalf, may be affected by the laws or regulations of the relevant jurisdictions in which they are located. Any failure to comply with the applicable restrictions may constitute a violation of the securities laws or regulations of any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person. Further details in relation to Overseas Shareholders will be contained in the Scheme Document.

Unless otherwise determined by Bidco or required by the Takeover Code, and permitted by applicable law and regulation, the Acquisition will not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws or regulations in that jurisdiction and no person may vote in favour of the Scheme by any such use, means, instrumentality or from within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws or regulations of that jurisdiction. 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, without limitation, agents, custodians, nominees and trustees) must not mail or otherwise forward, distribute or send it in or into or from any Restricted Jurisdiction. Doing so may render invalid any related purported vote in respect of the Acquisition. If the Acquisition is implemented by way of an Offer (unless otherwise permitted by applicable law and regulation), the Offer may not be made directly or indirectly, in or into, or by the use of mails or any means or instrumentality (including, but not limited to, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or of any facility of a national, state or other securities exchange of, any Restricted Jurisdiction and the Offer may not be capable of acceptance by any such use, means, instrumentality or facilities.

Further details in relation to overseas shareholders will be included in the Scheme Document.

Notice to US G&H Shareholders

The Acquisition relates to the shares of an English company and is being made by means of a scheme of arrangement provided for under the laws of England and Wales. A transaction effected by means of a scheme of arrangement is not subject to the tender offer or proxy solicitation rules under the US Securities Exchange Act of 1934 (the "US Exchange Act"). Accordingly, the Acquisition is subject to the disclosure requirements and practices applicable in the UK to schemes of arrangement which differ from the disclosure requirements of the US tender offer and proxy solicitation rules. The financial information included in this announcement has been prepared in accordance with generally accepted accounting principles of the UK and thus may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the US.

If, in the future, Bidco exercises its right to implement the Acquisition by way of an Offer, which is to be made into the US, such Offer will be made in compliance with the applicable US laws and regulations.

It may be difficult for US holders of G&H Shares to enforce their rights and any claim arising out of the US federal laws, since Bidco and G&H are located in a non-US jurisdiction, and some or all of their officers and directors may be residents of a non-US jurisdiction. US holders of G&H Shares may not be able to sue a non-US company or its officers or directors in a non-US court for violations of the US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's judgement.

In accordance with normal UK practice and pursuant to Rule 14e-5(b) of the US Exchange Act, ACP or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, G&H Shares outside of the US, other than pursuant to the Acquisition, until the date on which the Acquisition becomes Effective, lapses or is otherwise withdrawn. Also, in accordance with Rule 14e-5(b) of the US Exchange Act, J.P. Morgan Cazenove will continue to act as an exempt principal trader in G&H Shares on the London Stock Exchange. These 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 a Regulatory Information Service and will be available on the London Stock Exchange website, www.londonstockexchange.com.

US G&H Shareholders also should be aware that the transaction contemplated herein may have tax consequences in the US and, that such consequences, if any, are not described herein. US G&H Shareholders are urged to consult with legal, tax and financial advisers in connection with making a decision regarding this transaction.

Forward-Looking Statements

This announcement (including information incorporated by reference in this announcement), oral statements made regarding the Acquisition, and other information published by Bidco and G&H contain statements which are, or may be deemed to be, "forward-looking statements". Forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and projections of the management of Bidco and G&H about future events, and are therefore subject to risks and uncertainties which could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements.

The forward-looking statements contained in this announcement include statements relating to the expected effects of the Acquisition on Bidco and G&H (including their future prospects, developments and strategies), the expected timing and scope of the Acquisition and other statements other than historical facts. Often, but not always, forward-looking statements can be identified by the use of forward-looking words such as "prepares", "plans", "expects" or "does not expect", "is expected", "is subject to", "budget", "projects", "synergy", "strategy", "scheduled", "goal", "estimates", "forecasts", "cost-saving", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or statements that certain actions, events or results "may", "could", "should", "would", "might" or "will" be taken, occur or be achieved. Forward-looking statements may include statements relating to the following: (i) future capital expenditures, expenses, revenues, earnings, synergies, economic performance, indebtedness, financial condition, dividend policy, losses and future prospects; (ii) business and management strategies and the expansion and growth of Bidco's, G&H's, any member of the Bidco Group's or any member of the G&H Group's operations and potential synergies resulting from the Acquisition; and (iii) the effects of global economic conditions and governmental regulation on Bidco's, G&H's, any member of the Bidco Group's or any member of the G&H Group's business.

Although Bidco and G&H believe that the expectations reflected in such forward-looking statements are reasonable, Bidco and G&H can give no assurance that such expectations will prove to be correct. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements.

These factors include, but are not limited to: the ability to complete the Acquisition; the ability to obtain requisite regulatory and shareholder approvals and the satisfaction of other Conditions on the proposed terms and schedule; changes in the global political, economic, business and competitive environments (including exposures to terrorist activities, the UK's exit from the European Union, Eurozone instability, the Russia-Ukraine conflict, the ongoing conflicts in the Middle East and disruption in business operations due to reorganisation activities) and in market and regulatory forces; changes in future exchange and interest rates; changes in tax rates; future business combinations or disposals; changes in general economic and business conditions; changes in the behaviour of other market participants; changes in the anticipated benefits from the proposed transaction not being realised as a result of changes in general economic and market conditions in the countries in which Bidco and G&H operate, weak, volatile or illiquid capital and/or credit markets, changes in tax rates, interest rate and currency value fluctuations, the degree of competition in the geographic and business areas in which Bidco and G&H operate and changes in laws or in supervisory expectations or requirements; the timing impact and other uncertainties of future or planned acquisitions or disposals or offers, the inability to realise successfully any anticipated synergy benefits when the Acquisition is implemented (including changes to the G&H Board and/or employee composition); incurring and/or experiencing unanticipated costs and/or delays (including IT system failures, cyber-crime, fraud and pension scheme liabilities), or difficulties relating to the Acquisition when the Acquisition is implemented. Other unknown or unpredictable factors could cause actual results to differ materially from those expected, estimated or projected in the forward-looking statements. If any one or more of these risks or uncertainties materialises or if any one or more of the assumptions proves incorrect, actual results may differ materially from those expected, estimated or projected. Such forward-looking statements should therefore be construed in the light of such factors. Neither Bidco nor G&H, nor any of their respective associates or directors, officers or advisers, 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. You are cautioned not to place any reliance on these forward-looking statements.

Specifically, statements of estimated cost savings and synergies related to future actions and circumstances which, by their nature, involve risks, uncertainties and contingencies. As a result, the cost savings and synergies referred to may not be achieved, may be achieved later or sooner than estimated, or those achieved could be materially different from those estimated. Due to the scale of the G&H Group, there may be additional changes to the G&H Group's operations. As a result, and given the fact that the changes relate to the future, the resulting cost synergies may be materially greater or less than those estimated.

Other than in accordance with their legal or regulatory obligations (including under the Takeover Code, the AIM Rules, the Market Abuse Regulation and the Disclosure Guidance and Transparency Rules) neither Bidco nor G&H is under any obligation, and Bidco and G&H expressly disclaim any intention or obligation, to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Dealing and Opening Position Disclosure Requirements

Under Rule 8.3(a) of the Takeover Code, any person who is interested in 1% 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) of the Takeover Code 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 Takeover Code, any person who is, or becomes, interested in 1% 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(s), 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 be deemed to be a single person for the purpose of Rule 8.3.
