Item 3.  Source and Amount of Funds or Other Consideration.

On June 28, 2019, Cummins and The Hydrogen Company (“H2C”) entered into a Funding and Investment Agreement, pursuant to which they agreed, among other things: (i) to cooperate with respect to an acquisition of the Issuer; (ii) to allow H2C to contribute its common shares of the Issuer, representing approximately 18.6%, in exchange for common shares of Purchaser, in lieu of receiving cash in connection with Purchaser’s acquisition of the Issuer; (iii) to allow H2C to increase its position in the capital of Purchaser up to 19.9%; and (iv) to certain governance arrangements upon completion of an Acquisition Transaction, as defined below.

In addition, on June 28, 2019, Cummins, Purchaser and H2C entered into a Voting and Support Agreement, pursuant to which H2C agreed to vote its common shares of the Issuer in favor of the Acquisition Transaction (as defined below).

On June 28, 2019, Cummins and Purchaser entered into an Arrangement Agreement with the Issuer pursuant to which Cummins (through the Purchaser) intends to acquire 100% of the Issuer’s outstanding common shares (“Shares”) through an arrangement under section 192 of the Canada Business Corporations Act (the “Acquisition Transaction”). Cummins (through the Purchaser) will acquire all the Shares of the Issuer that are not held by H2C in an all-cash transaction, paying US$15.00 per Share. In addition, Cummins will lend the Issuer the aggregate amount payable for all of the issued and outstanding options, deferred share units, performance share units and restricted share units. The holders of those units will surrender them to the Issuer for cancellation and receive consideration for the units. The total enterprise value for the Acquisition Transaction is estimated to be US$290 million.

Cummins has sufficient funds available to fund the entire purchase price for the Acquisition Transaction through its existing cash balances. As of Cummins’ Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2019, as filed with the Securities and Exchange Commission on April 30, 2019, Cummins disclosed cash and cash equivalents of US $1.3 billion.

As a result of the Acquisition Transaction and the agreements with H2C, Purchaser will become the sole shareholder of the Issuer. The Issuer and/or Cummins and Purchaser, as applicable, will file all necessary notices, and make all necessary regulatory filings, to cause the Shares to be delisted from the Toronto Stock Exchange and the Nasdaq Global Market, to terminate all open registration statements, and to cause the Shares to be deregistered with the Ontario Securities Commission and the U.S. Securities and Exchange Commission.

A copy of the Funding and Investment Agreement accompanies this Schedule 13D as Exhibit 99.1. A copy of the Voting and Support Agreement accompanies this Schedule 13D as Exhibit 99.2.

Item 4.  Purpose of Transaction.

As described in Item 3, the purpose of transaction is for Purchaser directly (and Cummins and H2C indirectly) to acquire 100% of the outstanding Shares of the Issuer and to continue the business of the Issuer. The Issuer will become wholly owned by the Purchaser, and the Issuer’s securities will no longer be registered with any securities authorities in Canada or the United States or registered or reported on any stock exchanges or inter-dealer quotation systems.

Subject to certain conditions in the Arrangement Agreement, when the Acquisition Transaction is closed and becomes effective, the members of the boards of directors of the Issuer and

8

its subsidiaries will resign, to the extent that the Purchaser may request, in favor of persons nominated by the Purchaser.

The foregoing description of intentions and plans is subject to termination, evolution, modification, or change at any time, without notice, prior to closing the Acquisition Transaction, and there can be no assurance that the matters described above will ultimately be carried out in this manner.
