Dear Andrew,

RE : PRICE QUERY - SILEX SYSTEMS LIMITED

We refer to your letter dated 9 May 2014 and respond to each question as follows:

1. Is the Company aware of any information concerning it that has not been announced to the market which, if known by some in the market, could explain the recent trading in its securities? Company response:

The company is not aware of any information concerning it that has not been announced which, if known, could be an explanation for recent trading in the securities of the Company.

2. If the answer to question 1 is "yes": a) Is the Company relying on Listing Rule 3.1A not to announce that information under Listing Rule 3.1? Please note that the recent trading in the Company's securities would suggest to ASX that such information may have ceased to be confidential and therefore the Company may no longer be able to rely on Listing Rule 3.1A. Accordingly, if the answer to this question is "yes", you need to contact us immediately to discuss the situation. b) Can an announcement be made immediately? Please note, if the answer to this question is "no", you need to contact us immediately to discuss requesting a trading halt (see below). c) If an announcement cannot be made immediately, why not and when is it expected that an announcement will be made?



Company response: N/A


3. If the answer to question 1 is "no", is there any other explanation that the Company may have for the recent trading in its securities? Company response:

The company has no other explanation for the price decrease in the securities of the Company, other than the possibility that there is focus in the market relating to two of the Company's key activities:
i) The Paducah Laser Enrichment Plant Opportunity: Silex can confirm that negotiations continue between General Electric-Hitachi Global Laser Enrichment LLC (GLE) and the US Department of Energy (DOE) with regard to GLE's proposal to establish a laser enrichment facility in Paducah, Kentucky (the "Paducah Laser Enrichment Facility" or "PLEF"). The DOE announced in November 2013 that GLE's proposal for the potential establishment of a commercial uranium tails processing facility, based upon the SILEX Technology, had been selected for future operations at the Paducah uranium enrichment site (refer to ASX release dated 28/11/13). This led to the commencement of confidential negotiations between GLE and the DOE, which are expected to be completed as early as the current quarter.
ii) ARENA Conditional Funding Contribution for Proposed Solar Systems Mildura Power Station Project: There is considerable speculation in the media regarding future funding capabilities of the Australian Renewable Energy Agency (ARENA) in light of reports on the Federal Government's Budget planning, including with regard to conditional funding commitments to the proposed 100MW Solar power station being planned by Silex subsidiary Solar Systems Pty Ltd. At this stage the Company continues to proceed with the Mildura project planning and awaits the outcome of the Federal Budget and further advice from ARENA before making any further comment.

4. Please confirm that the Company is in compliance with the Listing Rules and, in particular, Listing Rule 3.1. Company response:

The Company understands its continuous disclosure obligations and believes that it is in compliance with listing rule 3.1.
We trust that this response satisfies your query, Further information on the Company's activities can be found on the Silex website: www.silex.com.auor by contacting the persons listed below.
