Posting of Scheme Document

On 28 October 2015, it was announced that the board of Orca Bidco Limited ("Orca") and the Independent Directors of OpSec Security Group plc ("OpSec") had reached agreement on the terms of a recommended cash offer for the entire issued share capital of OpSec not already owned or contracted to be acquired by Orca (the "Acquisition"). The Acquisition is to be effected by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Scheme").

Under the terms of the Scheme, Scheme Shareholders will receive 55 pence in cash (the "Cash Consideration") for each Scheme Share, valuing the entire issued share capital of OpSec at approximately £66.7 million.

OpSec announces that tomorrow it will post to OpSec Shareholders a scheme document in relation to the Acquisition, setting out amongst other things the full terms and conditions of the Scheme, an explanatory statement, an expected timetable of principal events and details of the actions to be taken by OpSec Shareholders (the "Scheme Document").

Overseas Shareholders

The release, publication and distribution of this announcement in jurisdictions other than the United Kingdom may be restricted by the laws of those jurisdictions and therefore persons into whose possession this announcement comes should inform themselves about and observe any such restrictions. Failure to comply with any such restrictions may constitute a violation of the securities laws of any such jurisdiction. This announcement has been prepared for the purpose of complying with English law and the 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.

Unless otherwise determined by Orca or required by the Code, and permitted by applicable laws and regulations, copies of this announcement and any formal documentation relating to the Acquisition and the Management Arrangements are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in, into or from any Restricted Jurisdiction, and persons receiving such documents (including custodians, nominees and trustees) must not mail or otherwise forward, distribute or send them in, into or from any Restricted Jurisdiction. If the Acquisition is implemented by way of a Takeover Offer (unless otherwise permitted by applicable law and regulation), the Takeover Offer may not be made directly or indirectly, in 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 Takeover Offer may not be capable of acceptance by any such use, means, instrumentality of facilities.

Unless otherwise determined by Orca or required by the Code, and permitted by applicable law and regulation, the cash offer shall not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction and no person may vote in favour of the offer by any such use, means, instrumentality or form within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction.

Persons who are not resident in the United Kingdom should inform themselves of, and observe, any applicable requirements. In particular, the ability of persons who are not resident in the United Kingdom to vote their Scheme Shares with respect to the Scheme at the Court Meeting or to execute and deliver forms of proxy appointing another to vote at the Court Meeting on their behalf, may be affected by the laws of the relevant jurisdiction in which they are located or of which they are citizens. Any failure to comply with such requirements may constitute a violation of the securities laws of any such jurisdiction. To the fullest extent permitted by applicable law, all persons involved in the Acquisition and the Management Arrangements disclaim any responsibility or liability for the violation of such requirements by any person. Further details in relation to Overseas Shareholders will be contained in the Scheme Document.

Notice to US Shareholders

The Acquisition relates to the shares of an English company that is not registered under the Exchange Act and is being made by means of a scheme of arrangement provided for and governed under English company law and, in particular, Part 26 of the Companies Act 2006. A transaction effected by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the Exchange Act. Accordingly, the Acquisition is subject to the disclosure requirements, rules and practices applicable in the United Kingdom to schemes of arrangement, which differ from the disclosure requirements of United States proxy solicitation or tender offer rules under the Exchange Act. If, in the future, Orca exercises the right to implement the Acquisition by way of a Takeover Offer and determines to extend the offer into the United States, the Acquisition will be made in compliance with applicable United States securities laws and regulations, including the applicable Exchange Act tender offer rules.

Financial information included in this announcement and the Scheme Document has been or will be prepared in accordance with accounting standards applicable in the UK that 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 United States.

It may be difficult for US holders of OpSec Shares to effect service of process within the United States on Orca, OpSec and/or any of their respective officers and directors or to enforce their rights and any claims arising out of US federal securities laws, since Orca and OpSec 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 OpSec 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 courts' judgement.

Each United States holder of OpSec Shares is urged to consult with his independent professional adviser regarding any acceptance of the Acquisition and/or the Management Arrangements including, without limitation, to consider the tax consequences associated with such shareholder's election to participate in the Acquisition and/or the Management Arrangements.

The Independent Directors accept responsibility for the information contained in this announcement relating to OpSec, the OpSec Group, the OpSec Directors, their close relatives and related trusts and companies and including, for the avoidance of doubt, the recommendation in respect of the Acquisition (but not the Management Arrangements) referred to in this announcement and set out in paragraph 17 of Part 1 of the Scheme Document. To the best of the knowledge and belief of the Independent Directors, who have taken all reasonable care to ensure that such is the case, the information contained in this announcement for which they are responsible is in accordance with the facts and does not omit anything likely to affect the import of that information.

The OpSec Directors (other than the Independent Directors) accept responsibility for the information contained in this announcement relating to OpSec, the OpSec Group, the OpSec Directors, their close relatives and related trusts and companies but excluding, for the avoidance of doubt, the recommendations of the Independent Directors referred to in this announcement.

Cautionary Note Regarding Forward-Looking Statements

This announcement contains certain forward-looking statements with respect to the financial condition, results of operations and business of OpSec and certain plans and objectives of Orca with respect thereto. These forward‑looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often use words such as "anticipate", "expect", "estimate", "target", "intend", "plan", "goal", "believe", "hope", "aims", "continue", "will", "may", "should", "would", "could" or other words of similar meaning. These statements are based on assumptions and assessments made by OpSec and/or Orca in light of their experience and their perception of historical trends, current conditions, future developments and other factors they believe appropriate. 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 and the factors described in the context of such forward-looking statements in this announcement could cause actual results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and you are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as at the date of this announcement. Neither OpSec nor Orca assumes any obligation to update or correct the information contained in this announcement (whether as a result of new information, future events or otherwise), except as required by applicable law.

There are several factors which could cause actual results to differ materially from those expressed or implied in forward-looking statements. Among the factors that could cause actual results to differ materially from those described in the forward-looking statements are changes in global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax rates and future business combinations and dispositions.

No statement in this announcement is intended as a profit forecast or estimate for any period and no statement in this announcement should be interpreted to mean that earnings or earnings per share for OpSec for current or future financial years would necessarily match or exceed the historical published earnings per share for OpSec.

Dealing and Opening Position Disclosure Requirements

Under Rule 8.3(a) of the Code, any person who is interested in 1 per cent or more of any class of relevant securities of an offeree company or of any paper 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 paper 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 paper offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) of the Code applies must be made by no later than 3.30 p.m. (UK time) on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 p.m. (UK time) on the 10th business day following the announcement in which any paper offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a paper offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1 per cent or more of any class of relevant securities of the offeree company or of any paper offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any paper 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 paper offeror, save to the extent that these details have previously been disclosed under Rule 8 of the Code. A Dealing Disclosure by a person to whom Rule 8.3(b) of the Code applies must be made by no later than 3.30 p.m. (UK 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 paper offeror, they will be deemed to be a single person for the purpose of Rule 8.3 of the Code.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4 of the Code).
