If at or before the end of the period during which the offer is open for acceptance (the "Offer Period"), Mosman has a Relevant Interest in such number of Trident Shares which represents at least 90% of the aggregate of all Trident Shares on issue at the end of the Offer Period, then the Company will compulsorily acquire the remaining Trident Shares in accordance with the relevant provisions of the Corporations Act 2001 (Cth).

If Mosman's Relevant Interest in the Trident Shares is equal to or more than 50.1% and less than 90% of the aggregate of all Trident Shares on issue at the end of the Offer Period (and the Offer becomes unconditional), then two of the current Trident Directors, being Messrs Haslam and Carruthers, will resign, and Messrs Barr and Carroll will be appointed as two of the three Trident Directors. In addition Mosman will undertake a strategic review of Tridents assets and operations.

If Mosman receives acceptances for less than 50.1% of the Trident Shares, it will not proceed with the Offer.

Additional Arrangements

Mosman and Trident have entered into a loan agreement pursuant to which Mosman agreed to loan Trident A$750,000 for Trident to utilise to repay certain third party creditors as well as for general working capital expenses. Mosman has advanced an initial loan of A$185,000 ("Initial Loan") and a further loan of A$565,000 ("Further Loan") will be advanced on Mosman acquiring a relevant interest in 50.1% of Trident Shares and the Offer becoming unconditional.

Trident has agreed to pay Mosman a reimbursement fee of A$150,000 in certain circumstances. Similarly Mosman has agreed to pay Trident a reimbursement fee of A$150,000 if there is a material breach of the bid implementation agreement entered into on 2 July 2014 by Mosman and that breach is not remedied within 10 Business Days.

2.    improving access to capital markets, likely to be able to provide additional capital to development projects and to support the valuation of the combined entity;

3.    providing access to the expertise of the directors of Mosman, which will be brought to bear to accelerate the development of Trident's existing assets;

4.    providing the benefits of scale and of a diversified portfolio of exploration assets in order to present a more attractive investment proposition than Trident or Mosman as standalone entities; and

5.    deploying cash resources towards investment in near-production assets which present improved opportunities for shareholders of Mosman in the short-to-medium term.

Trident Board Recommendation

The Trident Directors have agreed to unanimously recommend the Offer in the absence of a Superior Proposal. In addition, the individual Trident Directors have undertaken to accept, or procure the acceptance of the Offer, in respect to Trident Shares that they or their associates own or control, in the absence of a Superior Proposal.
