Nel ASA: Signed final agreement to acquire Proton OnSite - extended announcement

(Oslo, 28 April 2017) Reference is made to the stock exchange announcement made
by Nel ASA ("Nel") on 27 February 2017 regarding the signed letter of intent to
acquire Proton Energy Systems, Inc. ("Proton OnSite").

Following satisfactory due diligence, Nel has today signed a final and binding
share purchase agreement with the F9 Investments LLC, the shareholder of Proton
OnSite, to acquire 100% of the shares of Proton OnSite (the "Transaction"). This
will make Nel the world's largest manufacturer of water electrolysers for
hydrogen production, offering both alkaline and PEM electrolysers in all
relevant sizes and markets.

The Transaction

Nel is acquiring 100% of the shares in Proton OnSite for a total consideration
of USD 70 million, on a cash and debt free basis and assuming a normalised
working capital as of closing (the "Purchase Price"). From the Purchase Price
there will be deducted certain amounts, to be calculated as of closing, to
adjust for (i) consideration payable by Proton OnSite to employees for
cancellation of a number of employee options, (ii) amounts owed by Proton OnSite
to its previous shareholder as of closing, and (iii) transaction expenses
payable by Proton OnSite on closing. Certain Proton OnSite employee option
holders will receive Nel options as consideration for cancellation of their
Proton OnSite options. The value of such is to be calculated per closing and
deducted from the Purchase Price.

The Purchase Price will be financed through USD 20 million in cash and USD 50
million in new shares (the "Consideration Shares") from Nel, to be adjusted as
per the above adjustment mechanisms. The Consideration Shares will be issued on
the closing date of the Transaction and the closing cash amount will be paid at
the same time.

The Transaction values each Nel Consideration Share at NOK 2.72 per share. 50%
of the Consideration Shares will be subject to lock-up until the first
anniversary of closing of the Transaction, while the remaining Consideration
Shares will be subject to lock-up until the second anniversary of closing.

A subsequent adjustment of the Purchase Price will be made following closing,
based on the amounts of net debt and working capital of Proton OnSite as of
closing. The closing adjustment will be made by Nel issuing additional new
shares to Proton OnSite's shareholder, or Nel receiving previously issued
Consideration Shares back from Proton OnSite's shareholder, as the case may be.

Closing of the agreement is subject to certain conditions, including relevant
public approvals and other third party consents, absence of material adverse
effects and correctness of representations. The timing of closing of the
Transaction depends on satisfactory fulfilment of these conditions, including
the public approval process, but is expected to occur around June / July 2017.

Carnegie acts as financial advisor to Nel in connection with the Transaction.
