To BPI shareholders and, for information only, to participants in the BPI share schemes and persons with information rights

Dear BPI Shareholder

RPC Group Plc Trading Update

This morning, RPC Group Plc ("RPC") released a trading update for the period from 1 April 2016 to 30 June 2016 ahead of their Annual General Meeting being held on 13 July 2016. The boards of BPI and RPC are pleased to enclose a copy of this trading statement for your information.

Scheme Document Printing Issues

On 1 July 2016 you were notified that BPI had published a scheme document (the "Scheme Document") which contained a recommended cash and share offer by RPC to acquire the entire issued and to be issued share capital of BPI (the "Offer"). The Scheme Document contains the Offer and other relevant information, including notices of the meetings of the BPI shareholders which will be held on 25 July 2016 in connection with the Offer.

It has been brought to BPI's attention that due to an error in the printing run of the Scheme Document it is possible that a very small number of copies of the Scheme Document may have been issued with certain pages missing. The board of BPI wishes to ensure that you have received all of the relevant information about the Offer and accordingly you are asked to check that your copy of the Scheme Document contains all pages numbered 1 to 101.

You are encouraged to read the Scheme Document in full. Accordingly, if you find that you have received a copy of the Scheme Document which has any pages missing, then please contact BPI's registrars Computershare at The Pavilions, Bridgwater Road, Bristol, BS99 6ZZ, United Kingdom or on 0370 889 3238, who will arrange for a new hard copy of the Scheme Document to be sent to you.

Yours faithfully

Cameron McLatchie Jamie Pike

Chairman Chairman

Disclosure requirements of the Code

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 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 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) applies must be made by no later than 3:30 p.m. on the 10th Business Day following the commencement of the Offer Period and, if appropriate, by no later than 3:30 p.m. 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 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 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, 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 p.m. on the Business Day following the date of the relevant dealing.

Disclosures are therefore required of interests in the shares of RPC and BPI.

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.

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).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Takeover Panel's website at http://wwww.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the Offer Period commenced and when any offeror was first identified. Enquiries should be made of the Takeover Panel's Market Surveillance Unit on +44 (0) 20 7638 0129 if there is any doubt as to whether an Opening Position Disclosure or a Dealing Disclosure is required to be made.
