NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION IN WHOLE OR IN PART, IN, INTO OR FROM ANY JURISDICTION WHERE TO DO SO WOULD CONSTITUTE A VIOLATION OF THE RELEVANT LAWS OF SUCH JURISDICTION

Summary

• The boards of St Barbara and Allied Gold are pleased to announce that they have reached agreement on the terms of a recommended offer under which St Barbara will acquire the entire issued and to be issued ordinary share capital of Allied Gold (the "Offer"). It is intended that the Offer be implemented by way of a Court sanctioned scheme of arrangement under Part 26 of the Companies Act.
  
  
• Under the terms of the Offer, Scheme Shareholders will be entitled to receive A$1.025 in cash and 0.8 St Barbara Consideration Shares for each Allied Gold Share held at the Scheme Record Time.
  
  
• Based on the price of a St Barbara Share of A$2.12, being the Closing Price of a St Barbara Share on the Australian Securities Exchange on 28 June 2012, the Offer values the entire issued and to be issued share capital of Allied Gold at approximately £360 million and each Allied Gold Share at 176 pence (based on an exchange rate between Australian Dollars and pounds Sterling of 0.6468 at 5pm GMT on the day before the date of this announcement).
  
  
• The value of 176 pence for each Allied Gold Share represents a premium of approximately 92.3 per cent. over the Closing Price on the London Stock Exchange of 91.5 pence per Allied Gold Share on 28 June 2012, being the day before the date of this announcement, and, based on St Barbara's 30-day VWAP on the Australian Securities Exchange, a premium of approximately 74.5 per cent. over the 30-day VWAP on London Stock Exchange of 100 pence per Allied Gold Share for the period ending on 28 June 2012, being the day before the date of this announcement.
  
  
• St Barbara and Allied Gold believe that the combination has a clear strategic and financial rationale, is value enhancing, and provides benefits for the shareholders of the enlarged group including:
  
  
• Participation in an international diversified gold mining and exploration company, with the largest gold reserves and resources portfolio of any mid-tier ASX listed peer company;
  
  
• Complementary business, development and funding profiles, with the combined group enjoying a development profile spanning exploration to gold production, supported by St Barbara's strong cash flow generation;
  
  
• Proven operations management capabilities, with significant experience in developing and operating both open pit and underground operations;
  
  
• Reduced investment risk profile through a more diversified asset portfolio;
  
  
• A number of organic growth and cost saving opportunities, including:
  
  
  • Anticipated gold production growth from Allied Gold's assets, including the Simberi Oxide expansion and potential development of the Simberi Sulphides project;
    
    
  • Exploration upside opportunities in close proximity to current mining operations at Gold Ridge, Simberi and Gwalia, including greenfield opportunities (eg. Tabar-Tatau Islands); and
    
    
  • Improved production reliability and anticipated unit cost reductions for Allied Gold's assets through the implementation of improved mine planning methodology, operating systems and cost management frameworks; and
    
    
• Stock market re-rating potential driven by increased market capitalisation, enhanced and more diversified asset portfolio and greater financial capacity to invest in future growth and development opportunities.
  
  
• St Barbara is a public corporation incorporated under the laws of Australia. The St Barbara Shares are listed on the Australian Securities Exchange. St Barbara American Depositary Receipts have also been issued through Bank of NY Mellon. St Barbara is one of Australia's larger and more profitable ASX listed mid-tier gold producers, developers and explorers (code: SBM). St Barbara has three mines and two processing plants at Leonora and Southern Cross, in the Eastern Goldfields region of Western Australia, and over 5,000km² of prospective tenements across Australia. The Gwalia mine at Leonora is St Barbara's cornerstone asset. The Gwalia deposit has an Ore Reserve grade of 8.9 g/t Au, an expected mine life of at least eight years, and remains open to the south and at depth. As at 30 June 2011, St Barbara's Measured and Indicated Mineral Resources contained 5.2 million ounces of gold, inclusive of Ore Reserves containing 2.8 million ounces of gold, with a further 2.4 million ounces of gold contained in Inferred Resources¹.
  
  
• Allied Gold is a public limited company registered in England and Wales. Allied Gold is a South West Pacific gold producer, developer and exploration company listed on the Official List of the London Stock Exchange, the Australian Securities Exchange and the Toronto Stock Exchange (code: ALD). The company has two gold mines in operation: the Simberi gold project located on Simberi Island, the northern most island of the Tabar Islands Group in the New Ireland Province of eastern Papua New Guinea, and the Gold Ridge gold project located on Guadalcanal Island in the Solomon Islands. Allied Gold also controls 100% of the 260km² Tabar-Tatau exploration licences, which includes all of the Tabar Islands group not covered by the mining lease for Simberi. As at December 2011, Allied Gold's Measured and Indicated Mineral Resources contained 5.2 million ounces of gold, with a further 3.8 million ounces of gold of Inferred Resources².
  
  
• The cash consideration payable under the terms of the Offer will be funded from St Barbara's existing cash resources and additionally by using a A$120 million term loan facility provided by National Australia Bank Limited and Barclays Bank Plc. Consent has been obtained for Allied Gold's existing debt financing to remain in place after completion of the transaction. The combined group will have gearing of approximately 20%³. As at 31 March 2012, St Barbara had a closing cash balance of A$137 million.
  
  
• Allied Gold intends to post the Scheme Document on or around 16 July 2012.
  
  
• No dividends will be paid or declared by Allied Gold between the date of this announcement and the Effective Date.
  
  
• Allied Gold Shareholders will have the option to receive the cash portion of the consideration in either Australian Dollars or pounds Sterling, through electing to receive either currency on the Forms of Election, further details of which are set out in this announcement.
  
  
• The Allied Gold Directors are being advised by RBC Capital Markets ("RBC"). The Allied Gold Directors, who have been so advised by RBC, as the independent financial adviser for the purposes of Rule 3 of the City Code, consider the terms of the Offer to be fair and reasonable. In providing its advice to the Allied Gold Directors, RBC has taken into account the commercial assessments of the Allied Gold Directors.
  
  
• Accordingly, the Allied Gold Directors intend unanimously to recommend Allied Gold Shareholders to vote in favour of the Scheme and the resolutions at the Court Meeting and the General Meeting, as the Allied Gold Directors have irrevocably undertaken to do in respect of their entire beneficial holdings in Allied Gold, amounting to, in aggregate, 2,206,303 Allied Gold Shares, representing approximately 1.1 per cent. of the issued ordinary share capital of Allied Gold.
  
  
• St Barbara has also received irrevocable undertakings to vote in favour of the Scheme and the resolutions at the Court Meeting and the General Meeting from Baker Steel Capital Managers LLP, Franklin Advisers, Inc. and Resource Capital Fund III LP in respect of 38,764,657 Allied Gold Shares, representing 19.0 per cent. of the issued ordinary share capital of Allied Gold. St Barbara has also received letters of intent to vote in favour of the Scheme in respect of 29,820,383 Allied Gold Shares representing 14.6 per cent. of the issued ordinary share capital of Allied Gold. M&G Investment Management has also verbally committed to St Barbara to vote in favour of the Scheme in respect of their entire shareholding in Allied Gold (representing approximately 18.9 per cent. of the issued ordinary share capital of Allied Gold), in the absence of a superior proposal.
  
  
• St Barbara has therefore received total irrevocable undertakings from the Allied Gold Directors and certain other Shareholders in respect of Allied Gold Shares representing, in aggregate, 20.1 per cent. of the existing issued ordinary share capital of Allied Gold and letters of intent in respect of Allied Gold shares representing, in aggregate, 14.6 per cent. of the issued ordinary share capital of Allied Gold. This level of support from Allied Gold Shareholders provides a high degree of deal certainty. St Barbara and Allied Gold have around 30% common share ownership.
  
  
• The Offer is conditional on, inter alia, certain approvals by Allied Gold Shareholders and the sanction of the Scheme by the Court. In order to become effective, the Scheme must be approved by a majority in number of the Scheme Shareholders voting at the Court Meeting representing not less than 75 per cent. in value of the Scheme Shares held by the Scheme Shareholders present and voting in person or by proxy. It is expected that the Scheme Document, containing further information about the Offer and notices of the Court Meeting and General Meeting together with the Forms of Proxy, will be posted on or around 16 July 2012 and that the Offer and the resolutions required to implement the Scheme will be put to Allied Gold Shareholders at the Court Meeting and the General Meeting. Subject to the satisfaction, or where relevant, waiver of all relevant Conditions, the Scheme is expected to become effective in the third quarter of 2012. It will not be necessary for St Barbara to obtain the approval of its shareholders to implement the Offer as the transaction is being structured as a scheme of arrangement between Allied Gold and its shareholders⁴.
  
  

Commenting on the Offer, Tim Lehany, Managing Director and Chief Executive Officer of St Barbara, said:

"The strategic and financial logic of the combination is clear, driven by the complementary nature of the two companies and the strong organic growth profile of the combined business. It will deliver a more diversified asset portfolio spanning exploration to gold production. Strong and sustainable cash flow generation from the Gwalia mine in particular complements the significant growth potential at Simberi, where the geological potential to increase mineral resources and production is substantial. This will complement our existing organic growth agenda. The transaction is anticipated to be immediately NAV accretive for our shareholders and earnings per share accretive⁵ from the first full year following completion of the transaction⁶. We are pleased to have already secured support from Allied Gold shareholders representing some 54 per cent. of shares on issue."

Commenting on the Offer, Mark Caruso, Chairman and Founder of Allied Gold, said:

"The Board of Directors of Allied Gold unanimously supports the transaction and believes it to be a unique transformational opportunity with the potential to realise an immediate premium for shareholders. The transaction has the certainty of cash consideration coupled with an equity component to enable participation in the significant upside potential of the combined group. The investment attraction of the merged group is compelling, being one of the largest production and resource/reserve based mid-tier ASX listed gold companies, with a diversified portfolio of quality assets operating in multiple regional jurisdictions. The combined group will have a declining cost profile and exciting growth potential through near-term project development and exploration upside. "

Tim Lehany added, "We look forward to working with the Allied Gold team to leverage complementary skills across every part of the value chain from exploration to gold production. Together we can implement St Barbara's mine planning methodology, operating systems and cost management frameworks, to support production reliability improvements and cash operating cost reductions for the Allied Gold operations."

RECOMMENDED OFFER

for

Allied Gold Mining Plc ("Allied Gold")

by

St Barbara Limited ("St Barbara")

(to be implemented by way of a Scheme of Arrangement

under Part 26 of the Companies Act)

1. Introduction

The boards of St Barbara and Allied Gold are pleased to announce that they have reached agreement on the terms of a recommended offer under which St Barbara will acquire the entire issued and to be issued ordinary share capital of Allied Gold.

2. The Offer

It is intended that the Offer be implemented by way of a Court sanctioned scheme of arrangement under Part 26 of the Companies Act.

Pursuant to the Offer, which will be subject to the conditions and further terms set out below and in Appendix I and to the full terms and conditions which will be set out in the Scheme Document, Scheme Shareholders will receive:

for each Allied Gold Share A$1.025 in cash

and

0.8 St Barbara Consideration Shares

Based on the price of a St Barbara Share of A$2.12, being the Closing Price of a St Barbara Share on the Australian Securities Exchange on 28 June 2012, the Offer values the entire issued and to be issued share capital of Allied Gold at approximately £360 million and each Allied Gold Share at 176 pence (based on an exchange rate between Australian Dollars and pounds Sterling of 0.6468 at 5pm GMT on the day before the date of this announcement). The value of 176 pence for each Allied Gold Share represents a premium of approximately 92.3 per cent. over the Closing Price on London Stock Exchange of 91.5 pence per Allied Gold Share on 28 June 2012, being the day before the date of this announcement, and, based on St Barbara's 30-day VWAP on the Australian Securities Exchange, a premium of approximately 74.5 per cent. over the 30-day VWAP on London Stock Exchange of 100 pence per Allied Gold Share for the period ending on 28 June 2012, being the day before the date of this announcement.

The St Barbara Consideration Shares to be issued pursuant to the Offer are expected to represent approximately 33 per cent. of the issued share capital of St Barbara as enlarged by the acquisition of Allied Gold.

No dividends will be paid or declared by Allied Gold between the date of this announcement and the Effective Date.

The St Barbara Consideration Shares will rank equally in all respects with the existing St Barbara Shares and will be entitled to receive any dividends and/or other distributions declared or paid by St Barbara in respect of common shares of St Barbara with a record date on or after the date of their issue.

Allied Gold Shareholders will have the option to receive the cash portion of the consideration in either Australian Dollars or pounds Sterling, through electing to receive either currency on the Forms of Election. The exchange rate for conversion of the cash consideration from Australian Dollars into Sterling will be set by St Barbara as at four business days prior to (and inclusive of) the settlement date (being the date by which all consideration is to be provided to Allied Gold Shareholders), meaning that Allied Gold Shareholders who elect to receive cash consideration in pounds Sterling will bear the exchange risk on any fluctuations in the Australian Dollar/pounds Sterling exchange rate prior to four business days before the settlement date (inclusive). Allied Gold Shareholders who elect to receive the cash consideration in pounds Sterling will receive the cash consideration converted at the exchange rate set by St Barbara, less any conversion and commission costs incurred. Commission costs are not expected to exceed approximately 0.2 per cent. of the total cash consideration.

The Offer is conditional on, inter alia, certain approvals by Allied Gold Shareholders and the sanction of the Scheme by the Court. In order to become effective, the Scheme must be approved by a majority in number of the Scheme Shareholders voting at the Court Meeting representing not less than 75 per cent. in value of the Scheme Shares held by the Scheme Shareholders present and voting in person or by proxy.

St Barbara and Allied Gold, as permitted by Rule 21.2(b) of the City Code, shall cooperate in relation to obtaining any consents, clearances, permissions or waivers as may be necessary or expedient and making all filings and waiting periods as are required under the law, regulations or practices applied by any applicable regulatory authority in connection with the conditions set out in Part A of Appendix I to this announcement.

It is expected that the Scheme Document, containing further information about the Offer and notices of the Court Meeting and General Meeting together with the Forms of Proxy, will be posted on or around 16 July 2012 and that the Offer and the resolutions required to implement the Scheme will be put to Allied Gold Shareholders at the Court Meeting and the General Meeting which are expected to be held around early August 2012. Subject to the satisfaction, or where relevant, waiver of all relevant Conditions, the Scheme is expected to become effective in the third quarter of 2012.

Fractions of St Barbara Consideration Shares will not be issued to Allied Gold Shareholders pursuant to the Offer. If a fractional entitlement to part of a St Barbara Share arises from the calculation of the St Barbara Consideration Shares to be issued to an Allied Gold Shareholder, such fractional entitlement will be rounded down to the nearest whole number of St Barbara Shares.

3. Background to and reasons for the Offer

The combination will create an international diversified gold mining and exploration company with an anticipated market capitalisation of approximately A$1billion⁷ and forecast gold production of approximately 480,000 ounces in financial year ending 30 June 2012 and 435,000 ounces in the financial year ending 30 June 2013⁸. The combined group will operate three established and proven mines and a fourth operation in ramp-up phase, located in Australia and the South West Pacific, with production growth potential.

St Barbara and Allied Gold believe that the combination has a clear strategic and financial rationale, is value enhancing, and provides benefits for the shareholders of the enlarged group including:

• Participation in an international diversified gold mining and exploration company, with the largest gold reserves and resources portfolio of any mid-tier ASX listed peer company;
  
  
• Complementary business, development and funding profiles, with the combined group enjoying a development profile spanning exploration to gold production, supported by St Barbara's strong cash flow generation;
  
  
• Proven operations management capabilities with significant experience in developing and operating both open pit and underground operations;
  
  
• Reduced investment risk profile through a more diversified asset portfolio;
  
  
• A number of organic growth and cost saving opportunities, including:
  
  
  • Anticipated gold production growth from Allied Gold's assets, including the Simberi Oxide expansion and potential development of the Simberi Sulphides project;
    
    
  • Exploration upside opportunities in close proximity to current mining operations at Gold Ridge, Simberi and Gwalia, including greenfield opportunities (eg. Tabar-Tatau Islands); and
    
    
  • Improved production reliability and anticipated unit cost reductions for Allied Gold's assets through the implementation of improved mine planning methodology, operating systems and cost management frameworks; and
    
    
• Stock market re-rating potential driven by increased market capitalisation, enhanced and more diversified asset portfolio and greater financial capabilities to invest in future growth and development opportunities.
  
  

St Barbara and Allied Gold are both established producers with published Ore Reserves underpinning long life mines. The combination of the two companies materially enhances their individual profiles in terms of market capitalisation, Ore Reserves, Mineral Resources and production.

The combination will create a leading c. 435,000 ounce gold producer, with the largest gold reserves and resources portfolio in the Australian mid-tier gold sector. On a pro forma basis, the combined group would have:

• 5.9 million ounces of gold contained in Ore Reserves⁹, ranking it first in the Australian mid-tier gold sector¹⁰;
• 10.4 million ounces of gold contained in Measured and Indicated Resources and 6.2 million ounces of gold contained in Inferred Resources⁹, ranking it first in the Australian mid-tier gold sector on a total Mineral Resources basis¹⁰; and
• Forecast gold production of approximately 435,000 ounces in the financial year ending 30 June 2013¹¹, ranking it the largest Australian mid-tier gold mining and exploration company on a production basis¹⁰. The combined group's annual production profile would indicatively comprise:

• Gwalia, Leonora	175,000 ounces - 190,000 ounces
• King of the Hills, Leonora	55,000 ounces - 60,000 ounces
• Simberi, PNG	70,000 ounces - 80,000 ounces
• Gold Ridge, Solomon Islands	95,000 ounces - 105,000 ounces
• Marvel Loch, Southern Cross	20,000 ounces - 25,000 ounces
• Total	415,000 ounces - 460,000 ounces

Allied Gold has also previously indicated the potential to increase gold production at Simberi from 70,000 - 80,000 ounces to 95,000 ounces following completion of the current Simberi Oxide expansion project.

The substantially larger scale and enhanced financial strength of the combined group is expected to provide a platform to deliver on current development opportunities and exploration programs targeting new discoveries. The combined group will have substantial exposure to the gold price, with gold loans and hedging accounting for on average no more than 25% of pro forma annual production.

The combined group will have a development profile spanning exploration to gold production. St Barbara's established, proven and high cash flow margin operating assets at Gwalia and King of the Hills in particular complement Allied Gold's significant growth and expansion potential at Simberi and Gold Ridge. The combined group's access to a prospective land portfolio in both Australia and the South West Pacific may also provide further exciting organic growth opportunities from exploration. These opportunities are supplemented by St Barbara's existing organic growth projects including ongoing exploration programs.

The anticipated cash balance and cash flow generation of the combined group provides financial flexibility to pursue organic growth options.

The combination will create a diversified asset portfolio by location and type of gold deposit. In the combined group, no asset will represent more than approximately 35 per cent. of the Ore Reserve inventory or contribute more than approximately 40 per cent. of pro forma production for the financial year ending 30 June 2013¹².

The transaction is anticipated to be earnings per share accretive (before any fair value, other accounting adjustments and one-off integration costs) from the first full year following completion of the transaction and immediately NAV accretive to St Barbara shareholders¹³.

St Barbara and Allied Gold have complementary management capabilities with significant depth of management. The combined group will have broad operational management expertise and technical capabilities, with proven operating experience in Australia and the South West Pacific spanning each step of the value chain from exploration through to gold production. The combined group's management has a track record in developing and operating both open pit and underground operations, which will support potential expansion at Simberi and Gold Ridge, and expertise in managing the development of multiple, complex projects. St Barbara's business systems and operating capabilities will support improved production reliability, and cash operating cost reductions for the Allied Gold operations. The group's management capability is also strengthened by a dedicated Discovery and Growth team, focused on exploration and development, who have a broad knowledge of global gold assets and growth opportunities.

Specific cost reduction opportunities at Allied Gold's Gold Ridge operations may include¹⁴:

• Improved grade control and mine planning measures;
• Potential improvement in mining fleet utilisation to increase the volume of ore hauled;
• Increased mill recoveries through improved blending and ROM management; and
• Increased plant throughput through plant optimisation.

Specific cost reduction opportunities at Allied Gold's Simberi operations may include¹⁴:

• Increased plant throughput through completion of planned plant upgrades;
• Potential improvement in mining fleet utilisation to increase the volume of ore hauled;
• Reduced fuel costs for processing; and
• Reduced open pit strip ratio through improved grade control.

As an international diversified gold producer, the enhanced company scale has the potential to increase its coverage and weighting in indices. St Barbara is currently included in the S&P ASX 200 index and Allied Gold is currently included in the S&P ASX 300 index. Based on an anticipated market capitalisation of approximately A$1 billion¹⁵, following completion of the transaction St Barbara is expected to remain in the S&P ASX 200 index. The increased scale of the combined group may result in:

• Stronger investment interest;
• Improved share trading liquidity; and
• Potential re-rating to a level reflecting its position and the quality of its asset portfolio relative to its mid-tier peers with any re-rating benefits flowing to both sets of shareholders.

Specific benefits of the combination for St Barbara shareholders are expected to include:

• Acquisition of quality, long-life gold assets with exploration potential;
• Earnings per share accretive (before any fair value, other accounting adjustments and one-off integration costs) from the first full year following completion of the transaction and immediately NAV accretive¹⁶;
• Significant uplift in gold production, reserves and resources;
• Increased asset diversification with development profile spanning exploration to gold production, reducing investment risk profile; and
• Increased average mine life of the asset portfolio.

Specific benefits of the combination for Allied Gold shareholders are expected to include:

• Attractive premium and material cash component;
• Ability to participate in the significant upside potential of the combined group;
• Access to St Barbara's strong cash flow profile and financial capacity to fund development and expansion projects at Simberi and Gold Ridge and to advance near term exploration programmes on a timely basis;
• Access to St Barbara's proven management and technical capabilities, including underground development and mining skills; and
• A reduction in total cash costs, combined with an increase in overall gold production, reserves and resources¹⁷.

Following completion of the transaction, it is intended that St Barbara's existing senior management team and Board of Directors will remain in place. St Barbara expects to appoint up to two existing Directors of Allied Gold to the positions of either Non-Executive Director or consultant to the combined group (to be mutually agreed between St Barbara and Allied Gold).

4. Background to and reasons for the recommendation

The combination offers attractive value to Allied Gold shareholders, providing the ability to realise an immediate premium which includes a significant cash component. Allied Gold shareholders will also be able to participate in the significant upside potential of the combined group.

St Barbara's cash balance and expected cash flow generation will contribute to a robust capital structure for the combined group, and provides flexibility to fund Allied Gold's extensive suite of development and exploration opportunities, in particular the current expansion projects at Simberi. St Barbara's business profile is highly complementary to that of Allied Gold's, with St Barbara's established, proven and highly cash flow generative operating assets at Gwalia and King of the Hills underpinning the significant growth and expansion potential at Simberi and Gold Ridge. St Barbara also offers proven operational management capabilities, with a strong internal technical and development team to support and evaluate mining operations and growth opportunities.

St Barbara has stable production in Australia, with the Gwalia asset producing significant free cash flow underpinned by long life, high grade reserves. This reduces Allied Gold's overall risk profile and increases portfolio diversification.

5. Advisers and Recommendation

The Allied Gold Directors, who have been so advised by RBC Capital Markets, as the independent financial adviser for the purposes of Rule 3 of the City Code, consider the terms of the Offer to be fair and reasonable.

7. Information on St Barbara

St Barbara is a public corporation incorporated under the laws of Australia. The St Barbara Shares are listed on the Australian Securities Exchange. St Barbara American Depositary Receipts have also been issued through Bank of NY Mellon. St Barbara is one of Australia's larger and more profitable ASX listed mid-tier gold producers, developers and explorers (code: SBM). St Barbara has three mines and two processing plants at Leonora and Southern Cross, in the Eastern Goldfields region of Western Australia, and over 5,000km² of prospective tenements across Australia. The Gwalia mine at Leonora is St Barbara's cornerstone asset. The Gwalia deposit has an Ore Reserve grade of 8.9 g/t Au, an expected mine life of at least eight years, and remains open to the south and at depth. As at 30 June 2011, St Barbara's Measured and Indicated Mineral Resources contained 5.2 million ounces of gold, inclusive of Ore Reserves containing 2.8 million ounces of gold, with a further 2.4 million ounces of gold contained in Inferred Resources¹⁸.

St Barbara's Leonora operations comprise the Gwalia and King of the Hills underground mines, a processing plant at Gwalia, and the undeveloped Tower Hill deposit.

The Gwalia mining method is long hole open stoping with cement paste back fill. Mine plans for financial year ending 30 June 2012 are based on sourcing ore almost exclusively from the higher grade South West Branch lode, with the average grade mined for the year expected to increase from 6.3 g/t Au in financial year ending 30 June 2011 to 8.0 - 8.5 g/t Au in financial year ending 30 June 2012. This expected increase in grade underpins an anticipated increase in production over the period to 175,000 - 190,000 ounces of gold (from 131,133 ounces for the financial year ending 30 June 2011). As at 30 June 2011, Gwalia's Measured and Indicated Mineral Resources contained 3.2 million ounces of gold, inclusive of Ore Reserves containing 2.0 million ounces of gold, with a further 1.0 million ounces of gold contained in Inferred Resources¹⁸.

The processing plant at Gwalia is a conventional CIP circuit and has a nominal capacity of 1.2 million tonnes per annum of hard rock and up to 1.8 million tonnes per year when softer material is blended. Other surface infrastructure includes a gas-fired power station, a paste fill plant, and a refrigeration plant to cool the underground environment.

The King of the Hills underground mine is located at the site of the historical Tarmoola open pit. Gold production commenced ahead of schedule in May 2011. The mine is expected to produce at the rate of 55,000 - 60,000 ounces of gold per annum for at least another two and a half years. Ore mined is trucked 42 kilometres to the Gwalia processing plant for treatment to utilise the available processing capacity. Gold production from King of the Hills is protected by put and call options providing a price collar of between A$1,425 and A$1,615 per ounce. As at 30 June 2011, King of the Hills' Indicated Mineral Resources contained 0.3 million ounces of gold, inclusive of Ore Reserves containing 0.2 million ounces of gold, with a further 0.1 million ounces of gold contained in Inferred Resources¹⁸.

Tower Hill, which is located two kilometres from the Gwalia plant, had been identified as a potential underground opportunity. Further work is being undertaken to better understand the geological controls over the high gold grade domains and the potential for extending the mineralisation at Tower Hill. As at June 2011, Tower Hill's Indicated Mineral Resources contained 0.4 million ounces of gold, inclusive of Ore Reserves containing 0.3 million ounces of gold¹⁸.

At St Barbara's Southern Cross operations, ore is sourced from the Marvel Loch underground mine. Deep drilling has identified the presence of (non-gold bearing) pegmatite beneath the Marvel Loch mine, and diminishing grades in the northern lodes of the mine. Southern Cross operations are forecast to produce 90,000 - 100,000 ounces of gold in financial year ending 30 June 2012 and cease operations in the December quarter 2012, at which time the 2.2 million tonne per annum plant will go onto care and maintenance, unless alternative feed sources can be identified. The forecast remaining gold production from Marvel Loch is protected by put and call options commenced in August 2011, providing a price collar of between A$1,550 and A$1,610 per ounce. As at 30 June 2011, the Southern Cross' Measured and Indicated Mineral Resources contained 1.2 million ounces of gold, inclusive of Ore Reserves containing 0.2 million ounces of gold, with a further 1.0 million ounces of gold contained in Inferred Resources¹⁹.

St Barbara also has exploration tenements covering 5,000km² across Australia (including tenements at East Lachlan where the target is copper-gold porphyry mineralisation), where the company is currently undertaking a targeted series of drilling programmes in the most prospective areas.

St Barbara's core strategy is to drive shareholder value through a focus on lowering costs and increasing margins at existing assets, investing in exploration to target both greenfield and brownfield discoveries, and evaluating and investing in both internal and external growth opportunities. Leveraging value at St Barbara's Leonora operations is a key part of this strategy. Exploration expenditure in the financial year ended 30 June 2011 was A$22 million, with 10 targets planned to be drilled across 5,000km² of prospective land in the financial year ending 30 June 2012. St Barbara's evaluation of external growth opportunities is disciplined and underpinned by geological prospectivity, with a clearly defined set of investment criteria allowing the company to focus on value accretive opportunities.

For the year ended 30 June 2011, St Barbara produced 258,474 ounces of gold, including 131,133 ounces from Gwalia, 7,066 ounces from King of the Hills and 120,275 ounces from Southern Cross. The company generated revenue of A$360 million, EBITDA of A$125 million and net profit of A$69 million. On 19 April 2012, St Barbara announced its March quarter results for the three months ending 31 March 2012. Over this period, St Barbara produced 85,840 ounces of gold, bringing total production for the nine months to 31 March 2012 to 240,063 ounces of gold. As at 31 December 2011, St Barbara had total assets of A$594 million, cash and cash equivalents of A$110 million and shareholder's equity of A$478 million.

8. Information on Allied Gold

Allied Gold is a public limited company registered in England and Wales. Allied Gold is a South West Pacific gold producer, developer and exploration company listed on the Official List of the London Stock Exchange, the Australian Securities Exchange and the Toronto Stock Exchange (code: ALD). The company has two gold mines in operation: the Simberi gold project located on Simberi Island, the northern most island of the Tabar Islands Group in the New Ireland Province of eastern Papua New Guinea, and the Gold Ridge gold project located on Guadalcanal Island in the Solomon Islands. Allied Gold also controls 100% of the 260km² Tabar-Tatau exploration licences, which includes the entire Tabar Islands group not covered by the mining lease for Simberi. As at December 2011, Allied Gold's Measured and Indicated Mineral Resources contained 5.2 million ounces of gold, with a further 3.8 million ounces of gold of Inferred Resources²⁰.

Historically, the operations of Allied Gold comprised the gold mining business of Allied Gold Limited, incorporated and registered in Australia, and its subsidiaries. Allied Gold Limited was publicly traded on the Australian Securities Exchange from December 2003, the London Stock Exchange's AIM market from March 2006 and on the Toronto Stock Exchange from November 2009. In June 2011, the company re-domiciled to the United Kingdom and commenced trading on the London Stock Exchange Plc's Main Market for listed securities. As part of this process, Allied Gold shareholders and option holders were required to approve two interdependent schemes of arrangement to change the company's place of incorporation to the UK. All existing shares and options in Allied Gold Limited were exchanged for share or options in Allied Gold Mining Plc, a company incorporated in England and Wales which became the new holding company for the Allied Gold Group.

The company's major assets are its 100% owned Simberi gold project located on Simberi Island in Papua New Guinea, and its 100% owned Gold Ridge gold project located on Guadalcanal Island in the Solomon Islands.

Simberi is an open-pit mining operation, with an associated 2.0mtpa CIL plant for processing oxide ore. The mine is located within the 2,560ha Mining Lease ML136 on the eastern side of Simberi Island. Allied Gold is currently expanding gold production at Simberi from a current run rate of 70 koz per annum (based on production over the four quarters to March 2012) to a rate of approximately 100 koz per annum through the expansion and optimisation of the existing oxide plant to increase capacity to 3.5mtpa of ore. Further expansion of operations and production at Simberi is currently under review. Additional potential has been identified around the existing Simberi pits, and a near-mine exploration programme on the western side of Simberi Island is currently underway with the aim of identifying additional oxide material. As at December 2011, Simberi had Measured and Indicated Mineral Resources containing 3.3 million ounces of gold, with a further 3.18 million ounces of gold of Inferred Resources, including Proven and Probable Ore Reserves containing 2.0 million ounces of gold.

Gold Ridge was acquired by Allied Gold in 2009 through its acquisition of ASG. The company completed an A$150 million refurbishment and expansion of the existing plant at Gold Ridge to increase capacity from 2.0mtpa to 2.5mtpa in March 2011. First gold was produced from the refurbished Gold Ridge plant in March 2011. Gold Ridge is targeting production of approximately 95 - 105 koz per annum for a minimum eight years, and a regional exploration programme has also commenced to grow the resource base. As at December 2011, Gold Ridge had total Measured and Indicated Mineral Resources containing 1.9 million ounces of gold, with a further 0.62 million ounces of gold of Inferred Resources, including Probable Ore Reserves containing 1.1 million ounces of gold.

Allied Gold also controls 100% of the 260km² Tabar-Tatau exploration licences, which includes all of the Tabar Islands group not covered by the mining lease for Simberi. The main focus of the exploration programme is to target epithermal gold and copper-gold porphyry mineralisation. While exploration work at Simberi in 2011 was focused on proving up sulphide resources to support the potential installation of sulphide processing capacity, efforts in 2012 have shifted to identification of new oxide and sulphide deposits within the mining lease. New targets have been generated through reprocessing of earlier IP data and testing of these targets has started through soil sampling and diamond core drilling.

Allied Gold's core strategy is to achieve profitable growth and increase volume from current mining assets, with a particular focus on assets in the South West Pacific with favourable capital intensity. The central driver of this strategy is securing the group's supply of gold, which it intends to achieve through the development and expansion of existing mining operations.

Allied Gold's aim is to keep growing its critical mass in terms of resources, reserves and production capacity through exploration around its existing assets. The company is investing in excess of A$10 million annually into exploration, with programs around all of its producing assets and at greenfield projects in Papua New Guinea and the Solomon Islands, as the Directors seek to build on the position of the group as a prominent gold producer and explorer in the region. Allied Gold is also focused on the organic development of in-house projects and regional acquisitions of production or near-term production assets.

For the year ended 31 December 2011, Allied Gold produced 108,338 ounces of gold, including 57,284 ounces from Simberi and 51,054 ounces from Gold Ridge. The company generated revenue of US$146 million, EBITDA of US$29 million and net profit of US$(6) million. On 30 April 2012, Allied Gold announced its March quarter results for the three months ending 31 March 2012. Over this period, Allied Gold produced 34,107 ounces of gold, including 15,051 ounces from Simberi and 19,056 ounces from Gold Ridge. As at 31 December 2011, Allied Gold had total assets of US$621 million, working capital of US$68 million, cash and cash equivalents of US$22 million and shareholder's equity of US$507 million.

Allied Gold currently has good relationships with local landowners who are important stakeholders in mining activities in the region.

9. Management, employees and locations

St Barbara recognises the skills and experience of the existing management and employees of Allied Gold. Accordingly, St Barbara expects that Allied Gold's management will play an important role in the combined organisation. St Barbara intends to work with the management of Allied Gold to conduct a strategic review of its operations and business within the first three months following completion of the acquisition. The strategic review will involve consideration around potential areas for business integration, and how best to realise the combined group's growth opportunities and business improvement initiatives. At this stage, no decisions have been made by St Barbara in relation to the strategic review, which may, or may not, result in changes to the employee base, changes to locations from where the business operates, or a redeployment of Allied Gold's fixed assets. St Barbara will remain headquartered in Melbourne, Australia.

St Barbara has given assurances to the Allied Gold Directors that the existing employment rights of all Allied Gold employees will be fully safeguarded upon completion of the Offer.

St Barbara also expects to appoint up to two existing Directors of Allied Gold to the positions of either Non-Executive Director or consultant to the combined group (to be mutually agreed between St Barbara and Allied Gold), upon completion of the Offer.

In recognition for their additional work in relation to the Offer and throughout the Offer period, Allied Gold proposes to make performance bonus payments of A$500,000 in the case of the Chairman and A$125,000 in the case of each non-executive director, payable only in the event that the Chairman and such directors are not taking up any invited positions with the combined company post the Scheme becoming effective and are hence foregoing any future compensation they would have received had they remained on the board of the combined company for the next calendar year. St Barbara has agreed to these payments. Further details of the individual proposals for each director will be set out in the Scheme Document.

10. Allied Gold Optionholders

Allied Gold Optionholders will be contacted separately regarding the effect of the Offer on their rights and appropriate proposals will be made to such persons in due course. In summary Allied Gold Optionholders will have the opportunity to either (i) exercise their outstanding options and participate in the Scheme in relation to the resulting Shares; or (ii) cancel their options for a payment by St Barbara of A$0.29 for each option Share. The payment of A$0.29 for each option Share reflects the value of an option based on its current see through value, as adjusted using a Black Scholes valuation. The Black Scholes valuation takes into account, amongst other things, the remaining exercise period of the options.

Following the Effective Date, Allied Gold will be re-registered as a private limited company and its articles of association will be amended to ensure that any of the outstanding options held by Allied Gold Optionholders which are exercised after the Scheme Record Time will be automatically acquired by St Barbara for A$1.025 in cash and 0.8 St Barbara Consideration Shares for each Allied Share.

11. Financing the Offer

The cash consideration payable under the terms of the Offer will be funded from St Barbara's existing cash resources and additionally by using a term loan facility provided by National Australia Bank Limited and Barclays Bank Plc under a A$120 million syndicated facility agreement which is repayable on the earlier of four years after financial close (i.e. four years after the Scheme becomes effective) and 30 June 2016 in accordance with an agreed amortisation schedule. Lazard, Lead Financial Adviser to St Barbara, is satisfied that sufficient resources are available to satisfy in full the cash consideration payable to Allied Gold Shareholders under the terms of the Offer. Consent has been obtained for Allied Gold's existing debt financing to remain in place after completion of the transaction. The combined group will have gearing of approximately 20% ²¹. As at 31 March 2012, St Barbara had a closing cash balance of A$137 million.

Allied Gold Shareholders will have the option to receive the cash portion of the consideration in either Australian Dollars or pounds Sterling, through electing to receive either currency on the Forms of Election. The exchange rate for conversion of the cash consideration from Australian Dollars into Sterling will be set by St Barbara as at four business days prior to the settlement date, meaning that Allied Gold Shareholders who elect to receive cash consideration in pounds Sterling will bear the exchange risk on any fluctuations in the Australian Dollar/pounds Sterling exchange rate prior to four business days before the settlement date. The exchange rate for conversion will be based on the Australian Dollar/pounds Sterling rate quoted on Reuters page "RBA26", being the exchange rate sourced from the Reserve Bank of Australia which is fixed each day at 4pm Australian Eastern Standard Time. Allied Gold Shareholders who elect to receive the cash consideration in pounds Sterling will receive the cash consideration converted at the exchange rate set by St Barbara, less any conversion and commission costs incurred. Commission costs, which will be contractually agreed with National Australia Bank Limited and passed onto shareholders at the commercial rate, are not expected to exceed approximately 0.2 per cent. of the total cash consideration assuming a charge of 0.001 pounds Sterling per Australian Dollar on the exchange rate at conversion.

12. St Barbara Consideration Shares

The St Barbara Consideration Shares will be ordinary shares in the capital of St Barbara. The St Barbara Consideration Shares will rank equally in all respects with the existing St Barbara Shares and will be entitled to receive any dividends and/or other distributions declared or paid by St Barbara in respect of ordinary shares of St Barbara with a record date on or after the date of their issue.

The ordinary shares of St Barbara are listed on the Australian Securities Exchange under the symbol "SBM" and an application will be made for the St Barbara Consideration Shares to be listed on the Australian Securities Exchange. The St Barbara Consideration Shares will be subject to the provisions of certain Australian securities laws.

It is intended that the Offer will be effected by way of a court-sanctioned scheme of arrangement under Part 26 of the Companies Act. Following implementation of the Offer, Allied Gold will become a wholly-owned subsidiary of St Barbara, with current St Barbara and Allied Gold shareholders owning 67% and 33% respectively of the combined group. Allied Gold will cease to be listed on the London Stock Exchange, the Australian Securities Exchange and the Toronto Stock Exchange.

It will not be necessary for St Barbara to obtain the approval of its shareholders to implement the Offer as the transaction is being structured as a scheme of arrangement between Allied Gold and its shareholders²².

13. Disclosure of interests in Allied Gold

St Barbara confirms that it has today made an Opening Position Disclosure, setting out the details required to be disclosed by it under Rule 8.1(a) of the Code.

14. Structure of the Offer

It is intended that the Offer will be effected by way of a court-sanctioned scheme of arrangement under Part 26 of the Companies Act. The Scheme will be an arrangement between Allied Gold and the Scheme Shareholders and will be subject to the approval of the Court.

The purpose of the Scheme will be to provide for St Barbara to become the holder of the entire issued and to be issued ordinary share capital of Allied Gold. This is to be achieved by the cancellation of the Scheme Shares held by Scheme Shareholders and the application of the reserve arising from such cancellation in paying up in full such number of new ordinary shares of 10 pence each in Allied Gold which is equal to the number of Scheme Shares cancelled and issuing such new ordinary shares to St Barbara. St Barbara will subsequently pay the cash consideration and issue the St Barbara Consideration Shares to which Allied Gold Shareholders on the register of members at the Scheme Record Time are entitled pursuant to the terms of the Offer in consideration for the cancellation of the Scheme Shares and the allotment and issue to St Barbara of the new Allied Gold Shares pursuant to the Scheme.

To become effective, the Scheme will require, amongst other things, the approval by a majority in number of Scheme Shareholders representing at least 75 per cent. in value of the Scheme Shares held by such Scheme Shareholders voting, either in person or by proxy, at the Court Meeting (or any adjournment thereof), and the passing by the Allied Gold Shareholders of a special resolution necessary to implement the Scheme (including approving appropriate amendments to the articles of association of Allied Gold) at the General Meeting (or any adjournment thereof). In addition, the Scheme must be sanctioned, and the Capital Reduction must be confirmed, by the Court.

The Scheme will also be subject to certain conditions and certain further terms referred to in Appendix I of this announcement and to be set out in the Scheme Document.

Once the necessary approvals from Allied Gold Shareholders have been obtained and the other Conditions have been satisfied or (where applicable) waived, the Scheme will become effective upon the delivery of the Capital Reduction Court Order to the Registrar. The Scheme is expected to become effective in the second half of 2012. If the Scheme does not become effective on or before 10 October 2012, it will lapse and the Offer will not proceed (unless the parties agree otherwise with the consent of the Panel).

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 the General Meeting (and if they attended and voted, whether or not they voted in favour) and share certificates in respect of the Allied Gold Shares will cease to be valid and entitlements to Allied Gold Shares held within the CREST system will be cancelled.

The St Barbara Consideration Shares to be issued to Allied Gold Shareholders pursuant to the Scheme will be issued 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 voting rights and the rights to receive any dividends and/or other distributions declared or paid by St Barbara in respect of common shares of St Barbara with a record date on or after the date of their issue.

St Barbara reserves the right, with the consent of the Panel (where necessary), to elect to implement the Offer by way of a Takeover Offer as an alternative to the Scheme. Any such Takeover Offer will be subject to an acceptance condition of St Barbara having acquired (whether pursuant to the Offer or otherwise) such percentage (being more than 50 per cent.) of the Allied Gold Shares, as St Barbara may decide, having consulted with the Panel, and will otherwise be implemented on the same terms (subject to appropriate amendments), so far as applicable, as those which would apply to the Scheme, and in compliance with applicable laws and regulations.

Further details of the Scheme, including how Scheme Shareholders may participate in the Court Meeting and General Meeting, will be contained in the Scheme Document.

15. Expected Timetable

Allied Gold currently anticipates that:

(a)	it will despatch the Scheme Document, together with the Forms of Proxy, to Allied Gold Shareholders and, for information only, to Allied Gold Optionholders on or around 16 July 2012;
(b)	the Court Meeting and General Meeting will take place around early August 2012; and
(c)	subject to the Scheme becoming unconditional and effective in accordance with its terms, the Offer is expected to become effective in the third quarter of 2012, with the consideration being payable to Allied Gold Shareholders no later than 14 days after the Effective Date.

The timing of events which relate to the implementation of the Offer is, however, subject to the approval of the Court and is therefore subject to change. A full anticipated timetable will be set out in the Scheme Document.

If the Offer does not become effective by 10 October 2012, the Offer will lapse (unless the parties agree otherwise with the consent of the Panel).

16. Regulatory conditions

The Offer will be subject to the conditions and further terms set out below and in Appendix I and the full terms and conditions which will be set out in the Scheme Document. In particular, the Offer is subject to a condition that the Australian Treasurer (acting on the advice of the Foreign Investment Review Board ("FIRB")) approves the Offer or statutory periods have elapsed with no objection having been received from FIRB. St Barbara understands that the acquisition of Allied Gold is consistent with Australia's foreign investment policy.

17. Overseas Shareholders

If you remain in any doubt, you should consult an appropriate independent professional adviser in the relevant jurisdiction without delay.

Further details in relation to overseas Allied Gold Shareholders will be contained in the Scheme Document.

18. Delisting and re-registration

Upon or shortly after the Effective Date, it is intended that St Barbara will procure that Allied Gold makes applications to (i) cancel the listing of Allied Gold Shares on the UKLA's Official List, (ii) cancel trading in Allied Gold Shares on the London Stock Exchange's Main Market for listed securities and the Australian Securities Exchange and (iii) delist the Allied Gold Shares from the Toronto Stock Exchange.

On the Effective Date, Allied Gold will become a wholly-owned subsidiary of St Barbara and share certificates in respect of the Allied Gold Shares will cease to be valid and should be destroyed. Entitlements to Allied Gold Shares held within the CREST system will be cancelled on the Effective Date.

It is also proposed that on or following the Effective Date, Allied Gold will be re-registered as a private limited company. In addition the articles of association of Allied will be amended to that of a private limited company with a provision for St Barbara to automatically acquire any new Allied Gold Shares which may be required to be issued, following the Scheme becoming effective, in respect of any of the outstanding options under the Allied Gold Employee Option Plans, for A$1.025 in cash and 0.8 St Barbara Consideration Shares for each Allied Gold Share.

This announcement has been prepared for the purpose of complying with English law and the City Code and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of jurisdictions outside the United Kingdom.

Overseas shareholders

The availability of the Offer to Allied Gold Shareholders who are not resident in the United Kingdom, Australia or the United States or not located in Canada may be affected by the laws of the relevant jurisdictions in which they are located or of which they are resident. The release, publication or distribution of this announcement in certain jurisdictions may be restricted by law. Persons who are not resident in the United Kingdom, Australia or the United States or not located in Canada or who are subject to other jurisdictions should inform themselves of, and observe, any applicable requirements of their jurisdictions. Any failure to comply with the applicable restrictions may constitute a violation of the securities laws of any such jurisdiction. To the fullest extent permitted by applicable law, the companies involved in the Offer disclaim any responsibility or liability for the violation of such restrictions by any person. This announcement has been prepared for the purposes of complying with English law, the Listing Rules, the rules of the London Stock Exchange and the City Code and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of any jurisdiction outside the United Kingdom.

Further details in relation to overseas Allied Gold shareholders will be contained in the Scheme Document.

The Offer relates to the shares in an English company and is proposed to be made by means of a scheme of arrangement provided for under company law of the United Kingdom. The scheme of arrangement will relate to the shares of a UK company that is a 'foreign private issuer' as defined under Rule 3b-4 under the Securities Exchange Act of 1934, as amended (the "Exchange Act") and (b) a "designated foreign issuer" under applicable Canadian securities laws. A transaction effected by means of a scheme of arrangement is not subject to the shareholder vote, proxy and tender offer rules under Australian law, Canadian law or the Exchange Act. Accordingly, the Offer is subject to the disclosure requirements and practices applicable in the UK to schemes of arrangement, which differ from the disclosure requirements and practices of Australian, Canadian or US shareholder vote, proxy and tender offer rules. Financial information included in the relevant documentation will have been prepared in accordance with accounting standards applicable in the UK that may not be comparable to the financial statements of Australian, Canadian or US companies.

No securities regulatory authority in any Canadian jurisdiction has (a) approved or disapproved of the Offer; (b) passed upon the merits or fairness of the Offer; or (c) passed upon the adequacy or accuracy of the disclosure in this announcement. Any representation to the contrary is an offence in Canada.

Any securities to be offered pursuant to the Offer as described in this announcement have not been and will not be registered under the US Securities Act of 1933, as amended (the "Securities Act"), or under the securities laws of any state, district or other jurisdiction of the United States, or of Canada, Australia or Japan. Accordingly, such securities may not be offered, sold or delivered, directly or indirectly, in or into such jurisdictions except pursuant to exemptions from applicable requirements of such jurisdictions. The St Barbara Shares to be issued in exchange for Scheme Shares pursuant to the Scheme will be issued in reliance upon exemptions from the prospectus requirements of securities legislation in each province and territory of Canada. Subject to certain disclosure and regulatory requirements and to customary restrictions applicable to distributions of shares that constitute "control distributions", St Barbara Shares issued pursuant to the Scheme may be resold in each province and territory in Canada, however the first trade in such St Barbara Shares will be subject to the standard conditions that no unusual effort has been made to prepare the market or create demand, no extraordinary commission or consideration is paid and, if the selling shareholder is an insider or officer of St Barbara, such shareholder has no reasonable grounds to believe that St Barbara is in default of securities legislation.

If St Barbara exercises its right to implement the Offer by way of a Takeover Offer, the Offer will be made in compliance with all applicable regulations.

Copies of this announcement and formal documentation relating to the Offer will not be and must not be, mailed or otherwise forwarded, distributed or sent in, into or from any jurisdiction where to do so would violate the laws of that jurisdiction.
