                               COINSILIUM GROUP LIMITED                            

                            ("Coinsilium" or the "Company")                        

                            Coinsilium Invests in Rootstock                        

    Coinsilium Group Limited, the blockchain technology investment and development
    company, is pleased to announce that it has invested, and facilitated
    co-investment, for a total of USD$100,000 in RSK Labs Ltd ("RSK"), being 28.6%
    of the initial seed round and representing  approximately 2% of RSK.

    RKS operates Rootstock, a smart-contract platform built as a sidechain of the
    Bitcoin blockchain (a sidechain is separate from the main blockchain but
    interoperable with a two-way peg) that adds value and functionality to the core
    Bitcoin network by enabling smart contracts (transactions that can be
    programmed to complete autonomously as and when pre-set conditions are met). 
    The Rootstock team features Sergio Demián Lerner, a prominent member of the
    Bitcoin technical community, with vast experience in cryptocurrencies who has
    designed many improvements to the Bitcoin protocol, and created the first
    smart-contract enabled cryptocurrency in 2013. On November 2015, RSK released
    their foundational white paper "Bitcoin Powered Smart Contracts" that describes
    the RKS platform, Rootstock, which is targeted to be launched around mid-2016. 
    On 7 October 2015, Blockchain, cryptocurrency and smart contracts pioneer, Nick
    Szabo, tweeted about Rootstock: "Best of Bitcoin (currency and settlement
    system) + best of Ethereum (smart contract programming environment):"

    Coinsilium's wholly owned subsidiary, Seedcoin Limited ("Seedcoin"), has
    invested USD$50,000 (equivalent paid in bitcoin) on behalf of itself and an
    additional USD$50,000 (equivalent, paid in bitcoin) on behalf of Coinsilium's
    co-investors for a convertible instrument that provides the right to shares of
    RSK's equity at a pre-money valuation of not more than US$5,000,000. 
    Coinsilium, via Seedcoin, has therefore taken approximately 14% of RSK's total
    USD$350,000 initial seed round and upon conversion to shares at a US$5,000,000
    valuation, Coinsilium would hold approximately 1% of RSK.

    Cameron Parry, Coinsilium's Executive Chairman, commented: "We are delighted to
    announce that Coinsilium has acquired an early strategic stake in RSK and we're
    excited at the prospect that the Rootstock platform can potentially deliver the
    strength and security of Bitcoin with the smart contract capability of
    Ethereum.

    We are also pleased to be able to utilise our co-investor network to see
    Coinsilium and its co-investors contribute approximately 28% of Rootstock's
    initial seed funding round."

    Sergio Demián Lerner, Rootstock's Chief Scientist and co-founder, commented:
    "We are excited to have Coinsilium join us as an investor at this stage of the
    company.

    We have designed Rootstock to add value to the Bitcoin network by providing
    smart contracts capabilities through a merge-mined sidechain, thereby enabling
    sophisticated transactions as secure as the Bitcoin network.  Rootstock also
    provides Bitcoin miners and mining pools the opportunity to participate in the
    smart contracts revolution and an additional revenue stream via merge-mining."
