Issue of Equity and Close of Offer

The directors of Investec Structured Products Calculus VCT plc ("the Company")
are pleased to announce an allotment today (4 May 2010) of 767,540 ordinary
shares of 1p each ("Ordinary Shares") at £1 per share pursuant to the offer for
subscription that opened on 3 March 2010 ("Offer").

Application for the Ordinary Shares to be admitted to the Official List of the
UK Listing Authority and to trading on the London Stock Exchange's main market
for listed securities will be made at the earliest practical opportunity.

Following these allotments the issued share capital of the Company is 3,867,917
Ordinary Shares.

The directors further announce that the Offer has now closed.

The directors are encouraged by the level of investor demand for this first
funding round for the Company, particularly given its late launch date before
the end of the 2009/10 tax year. The directors have decided to close the share
offering on the planned date as both Investec and Calculus, the managers, are
keen to press ahead with the Company's investment plans.

Investec, as manager of the structured products portfolio, expects to announce
its first investments shortly. Calculus, as manager of the VCT qualifying
investments, is currently engaged in negotiation and/or due diligence on a
number of potential investments and expects to announce its first qualifying
investments in the near future.

The directors are currently reviewing funding plans with the two managers and
expect to announce further fundraising plans later this year.
