PERTH, Western Australia, Dec. 15 /CNW/ - Mantra Resources Limited ("Mantra" or "Company") (ASX:MRU, TSX:MRL) is pleased to announce it has received an all-cash offer from ARMZ Uranium Holding Co. (JSC Atomredmetzoloto) ("ARMZ") to acquire all of the issued shares in Mantra for A$8.00 per share (the "Offer Price") via a Board recommended Scheme of Arrangement (the "Scheme") under the Australian Corporations Act. This values Mantra at approximately A$1.16 billion.

The Offer Price of A$8.00 per share represents a 15.5% premium to the 20 day VWAP and a 21.2% premium to the 30 day VWAP on the ASX. The offer also values Mantra at US$10.26 per pound of resource, which is significantly higher than other substantial uranium developers.

The cash offer enables Mantra shareholders to realise immediate value for their Mantra shares and reflects the size, strategic nature and near-term development potential of the Mkuju River Project uranium deposit.

The Board, having taken advice from RBC Capital Markets as to the consideration being provided under the offer, has concluded that the transaction is in the best interests of Mantra shareholders.

Subject to an Independent Expert determining that the Scheme is in the best interests of Mantra shareholders, the Directors of Mantra have agreed to unanimously recommend ARMZ's offer and will vote in favour of the Scheme in the absence of a superior proposal.

In addition, Mantra's strategic shareholder, Highland Park S.A., which owns 13.5% of the outstanding fully diluted share capital in Mantra, has represented to Mantra that it will vote in favour of the Scheme in the absence of a superior proposal.

Furthermore, the Mantra Directors and Highland Park have undertaken to stand still in relation to their Mantra securities whilst the Scheme is being implemented.

Mantra's Comment
Peter Breese, CEO of Mantra, said "This clean, all-cash offer from ARMZ is compelling and reflects both the strategic significance of this asset as well as the current status of the project against the backdrop of a recent spike in the uranium price.  The offer crystallises immediate value for Mantra shareholders, providing them with the certainty of cash. 

We have taken advice from our financial and legal advisers and concluded that this offer is in the best interests of Mantra's shareholders.  Therefore, the Board and management, along with our strategic shareholder Highland Park, recommends this offer to Mantra shareholders, subject to confirmation by an Independent Expert's Report."

ARMZ's Comment
"Mantra's flagship asset, the Mkuju River Project, is a world class deposit.  Our offer for Mantra demonstrates this by providing Mantra shareholders with the opportunity to realise a cash consideration at a premium value.   We believe Mantra will complement our portfolio of assets and is consistent with our stated strategy of acquiring low cost, long life, geographically diverse assets." said Vadim Zhivov, Director General of ARMZ.

Scheme Implementation Agreement
Mantra has entered into a Scheme Implementation Agreement ("SIA") with ARMZ under which Mantra has agreed to propose a Scheme between Mantra and its shareholders for the acquisition of all Mantra shares by ARMZ for cash consideration of A$8.00 per Mantra share.

A summary of key terms of the SIA is attached as Annexure A to this announcement.

The Scheme is subject to a limited number of conditions that must to be satisfied or waived in order for the Scheme to be implemented and includes Australian Foreign Investment Review Board ("FIRB") approval being granted to ARMZ.  Further due diligence is not a condition.

The transaction is also subject to a number of other conditions precedent typical for a Scheme, including Australian court approvals and the approval of the requisite majority of Mantra shareholders at the Scheme meeting.

Mantra will shortly commission an Independent Expert to opine on whether the Scheme is in the best interests of Mantra shareholders.  The Mantra Directors' recommendation that shareholders vote in favour of the Scheme is subject to the Independent Expert determining that the Scheme is in the best interests of Mantra shareholders.

The SIA contains terms typical for a transaction of this nature, including "no shop" and "no talk" provisions (subject to typical Directors' fiduciary duty exemptions), a mutual break fee ("Break Fee") of 1% of transaction value payable in certain circumstances.

Payment of the Break Fee by Mantra is not subject to the outcome of the Scheme meeting and the Break Fee is not payable in the event that Mantra Directors withdraw their recommendation for the Scheme as a result of the Independent Expert finding that the Scheme is not in the best interests of Mantra shareholders.  A break fee is payable by ARMZ if ARMZ fails to pay the scheme consideration or for breaches of an obligation necessary for the implementation of the Scheme.  The mutual break fee contains mutual limitations of liability where the payment of the break fee on termination of the Scheme is in full and final settlement of all claims between the parties.

Summary of the Key Terms of the Scheme Implementation Agreement

A summary of the structure of the Scheme and an outline of the key terms and conditions of the SIA are set out below. Please refer to the Definitions in paragraph 9 when reading this summary.

1.	Structure of the Scheme
	Under the Scheme Mantra shareholders will transfer all their shares in Mantra to ARMZ in exchange for A$8.00 per share (Scheme Consideration).

2.	Conditions precedent
	Implementation of the Scheme is subject to the satisfaction or waiver of the following conditions precedent:

• Receipt of all necessary government agency approvals, including FIRB approval, and no court or regulatory authority taking steps to restrain the Scheme;
• Mantra shareholders and the court approve the Scheme;
• There is no action by a Government agency in consequence of, or in connection with, the Scheme which retrains, prohibits or impedes the implementation of the Scheme; and
• No 'Material Adverse Change' (as defined in the SIA) occurs.

3.	Recommendation of Board of Mantra
	The Board of Mantra has unanimously recommended that Mantra shareholders vote in favour of the Scheme subject to the following:

• the Independent Expert's report concluding that the Scheme is in the best interests of Mantra Shareholders; and
• in the absence of a Superior Proposal (as defined in the SIA).

The Board of Mantra has also stated that they will vote their shares in favour of the Scheme in the absence of a Superior Proposal.

4.	Exclusivity

(a)	No Shop/No Talk/No Due Diligence

• Until the Second Court Hearing Date, Mantra (and its Related Parties, employees, agents or Advisers) must not:
• directly or indirectly solicit, invite, encourage, initiate or otherwise facilitate any Competing Transaction  (as defined in the SIA) (No shop);
• negotiate or enter into or participate in negotiations or discussions with any other person regarding a Competing Transaction or potential Competing Transaction (No talk);
• grant any other person any right or access to conduct due diligence investigations in respect of Mantra or provide any non-public information relating to Mantra to another person that could contribute to the formulation of a Competing Transaction (No due diligence).

The no talk and no due diligence obligations do not apply to unsolicited Competing Transactions where in the opinion of the Mantra Board formed in good faith after receiving written advice from its legal and financial advisers such action or inaction (as the case may be) is necessary to discharge the fiduciary or statutory duties of the directors of Mantra (or to avoid a contravention of law).

(b)	Competing Transactions and ARMZ Right to Match

		If Mantra receives a written or verbal proposal for a Competing Transaction or is approached or requested by any person to engage in any activity that would breach its exclusivity obligations, it must promptly inform ARMZ of the fact and all material terms of any such proposal (including the price or value and the identity of the person) and of any amended proposal.
		Mantra must not enter into any agreement in relation to any such Third Party Proposal unless:

• it has notified ARMZ as described above;
• it has determined that it is a Superior Proposal;
• ARMZ has been given the opportunity to match any such proposal (and any amended proposal) within 5 Business Days of being notified.

If ARMZ submits to Mantra a written proposal which is on terms no less favourable than the Third Party Proposal, Mantra must proceed exclusively with ARMZ's proposal.

5.	Break Fee
	The Break Fee is the amount of A$11.6 million, being approximately 1% of the equity value of Mantra (including outstanding options and performance rights) as reflected in the Scheme Consideration.

Mantra must pay ARMZ the Break Fee if:

• any director of Mantra publicly recommends, promotes or otherwise endorses a Competing Transaction;
• Mantra accepts or enters into any agreement, arrangement or understanding regarding a Competing Transaction;
• a Competing Transaction in relation to Mantra is announced or open for acceptance before the Scheme becomes Effective and the person proposing the Competing Transaction acquires a relevant interest in more than 20% of the voting shares in Mantra;

• the Scheme does not become Effective because Mantra has failed to perform or satisfy its material obligations necessary for implementation of the Scheme.

(c)	Limitation of liability

	Both parties agree that the payment of the Break Fee by either of them allows them to terminate the SIA and constitutes full and final satisfaction and discharge of any and all liability to the other party under the SIA or otherwise and allows them to terminate the SIA.
	For example, if the Mantra Board recommends a Competing Transaction and Mantra pays the Break Fee to ARMZ or if ARMZ fails to pay the Scheme Consideration for any reason and ARMZ pays the Break Fee to Mantra, the transaction will not proceed and the parties will have no further liability to each other under the SIA or otherwise in relation to the transaction.

• if either party becomes obliged to pay the Break Fee; or
• if ARMZ publicly announces a takeover bid for Mantra shares at a price not less than the Scheme Consideration;
