PART III - NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR or the transition report or portion thereof could not be filed within the prescribed time period.

The Company’s Annual Report on Form 10-K for the year ended December 31, 2015, could not be filed within the prescribed period because the Company was unable to compile, disseminate and review certain information required in order to permit the Company to file a timely and accurate report on the Company’s financial condition. This inability could not have been eliminated by the Company without unreasonable effort or expense. On March 15, 2016, the Company announced that it was unable to pay its senior secured credit facility (“Credit Facility”) on the March 14, 2016 expiration date which resulted in an event of default under the Credit Facility as well as certain other secured debt instruments. The company is currently assessing accounting considerations and related liquidity disclosures around such defaults.

Part IV(3) Explanation

The Company anticipates that total revenues to be reported for continuing operations will increase by approximately 19% for calendar year 2015 as compared to revenues reported for calendar 2014. The increase in revenues for 2015 compared to 2014 is primarily attributable to the Company’s progress in introducing and commercializing fuel storage systems, growing its customer base, and gaining market share over the past year.

The Company also anticipates for its current period that: (i) its cost of revenues will increase approximately 31%, (2) its net operating loss will increase by approximately 14%, and (iii) its loss from continuing operations will increase by approximately 12%, compared to the reported amounts in the prior year period. The increase in cost of goods sold is primarily attributable to higher product sales and incremental expenses incurred associated with the introduction of new and next generation fuel storage modules, specific warranty charges to retrofit first generation fuel storage systems, and for the establishment of outside facilities that support the installation and servicing of its products.

As announced by the Company on March 15, 2016, the Company has engaged Mackinac Partners LLC as its financial advisor to assist the Company with negotiating with its creditors, and evaluating all options that may be available to the Company. There can be no assurance that the Company’s efforts will be successful or that the Company will not have to seek protection under federal bankruptcy laws.
