Dear Shareholder

Electronic Communications

This letter accompanies the Notice of Annual General Meeting 2013 ("Notice") of Dialight plc ("Dialight") to be held on 25 April 2013 at Glaziers Hall, 9 Montague Close, London Bridge, London SE1 9DD.

Shareholders have previously passed a resolution that enables Dialight to take advantage of certain provisions in the Companies Act 2006 that allow Dialight to supply documents; such as the Company's Annual Report and Accounts and the Notice to shareholders via its website, www.dialight.com. This will both speed up your access to Company documents and help us to reduce the cost and environmental impact of producing and distributing printed documents in large quantities.

The attached Shareholder Communications Form ("Form") explains the different ways you can choose to receive shareholder documents going forward. It also sets out what you need to do in relation to each of these options.

Please note that if you wish to continue to receive shareholder documents in hard copy, you must return the Form to the Company's Registrars; Equiniti, by no later than 18 April 2013. If you do not return the Form by this date, you will be treated as having agreed to the Company supplying you with shareholder documents by means of the Company's website.

You can, at any time, request a hard copy of any shareholder document by writing to the Company's Registrars and you can also, at any time, change your decision on how you wish to receive future shareholder documents.

Yours faithfully

Nick Giles
Company Secretary

Shareholder communications form

More information

Why are we being given this choice now?

The Companies Act 2006 includes provisions regarding shareholder communications which allow us to offer you greater choice in how we communicate with you. We last asked shareholders to consider their options for the receipt of documents in 2010.

What are the options?

You can choose to receive your communications electronically or in the traditional paper format. If you do not specifically elect to receive paper communications we will let you know by e-mail (if you have previously supplied your email address) or by letter that a shareholder document is available to view at www.dialight.com.

What do I need to do next?

Tell us how you want to receive your future shareholder communications:

• View shareholder documents on www.dialight.com

If you are happy to view shareholder documents in this way, Dialight will send you a notification whenever shareholder documents are available to view on the website. This will include full details of any software or technical requirements necessary to access the documentation. You can choose to have notifications sent by e-mail by registering online at www.shareview.co.uk by 18 April 2013. Any email is deemed to have been received by you 24 hours after it has been sent to the e-mail address on file. Alternatively, if you would prefer to receive notifications in hard copy by post, you do not need to take any further action at this time.

• Receive hard copies of shareholder documents by post

To receive shareholder documents in this way, you must complete and return the below detachable form of this letter by 18 April 2013 having chosen option 2. If you do not do this, your consent will be deemed to have been given to the Company sending or supplying documents or information by means of its website, www.dialight.com, and you will only receive notifications by post as described in the paragraph above.

What if I choose electronic communications but want a paper version of something?

You have the right to request, at no extra charge, hard copy versions of shareholder information or documentation at any time.

What if I change my mind?

Your election and contact details will stand until you tell us otherwise. You can change your selection by writing to Equiniti Limited, Aspect House, Spencer Road, Lancing, West Sussex BN99 6DA (shareholder helpline number 0871 384 2052).

Why should I reply?

These new arrangements will ensure that if you prefer to receive your documents in paper format then you can continue to do so, whilst enabling us to take advantage of the environmental and cost benefits arising from reduced paper usage, printing and distribution.

What happens if I don't do anything?

If you do not return this form or register online then shareholder documents or information will not be sent directly to you by post, but instead will be available for you to review following their publication on the Company's website www.dialight.com. You will receive notification of the availability of the documents by post.

Are there any exceptions to electronic communications?

If we are required to restrict the sending of any documents or information to any shareholder due to local laws of the jurisdiction in which you are resident or located, and as a result we are not permitted to use electronic means to communicate with shareholders, we will send you hard copies of the documents or information.
