In April 2016, the Company entered into a loan and security agreement (the "Agreement") with Hercules Capital, Inc. (“Hercules”) for an aggregate principal amount of up to $25.0 million, subject to certain terms and conditions. The Company received an initial term loan advance on the date of closing of $15.0 million. The Company took an additional loan advance of $5.0 million in September 2016 due to certain milestones being met (“Tranche II”). We may also have available a loan advance of $5.0 million beginning on the later of January 1, 2017 or the date certain milestones are met and June 15, 2017 (“Tranche III”). The loan is a 30 month secured facility and the term loan interest is currently 9.5%. Interest is paid on a monthly basis. As of October 31, 2016, interest only payments are required through November 1, 2017. If certain additional performance milestones are achieved, the interest only period would be extended to May 1, 2018. Upon completion of interest only payments, the loan balance and all accrued and unpaid interest is due and payable in equal monthly installments by October 1, 2018. Per the terms of the Agreement, there is an end of term charge of $1.7 million,which is being accreted over the thirty-month term using the effective interest rate method, which would increase to $2.1 million if the Company receives an additional $5.0 million advanced as discussed above.

As collateral for obligations under the Agreement, the Company granted Hercules a security interest in its existing and hereafter-acquired assets except for intellectual property and certain other excluded assets. Collateral does not include assets held by the Company's finance subsidiary or any project subsidiary thereof. The Company may continue to collateralize and finance its project subsidiaries through other lenders and partners. The loan contains a financial covenant whereby the Company is required to maintain an unrestricted cash balance of at least (a) 75% of the outstanding Loan balance plus (b) the amount of accounts payable (as defined under GAAP) not paid within 90 days of the date payment was issued.

In November 2015, the Company closed on a definitive Assistance Agreement with the State of Connecticut and received a disbursement of $10.0 million to be used for the first phase of the expansion project to expand the existing 65,000 square foot manufacturing facility in Torrington, Connecticut by approximately 102,000 square feet for a total size of 167,000 square feet. In conjunction with this financing, the Company entered into a $10.0 million Promissory Note and related security agreement, securing the loan with equipment liens and a mortgage on its Danbury, Connecticut location. Pursuant to the terms of the Note, payment of principal is deferred for the first four years. Interest at a fixed rate of 2.0% became payable beginning December 2015. The principal is payable over 15 years, and is predicated on certain terms and conditions, including the forgiveness of up to half of the loan principal if certain job retention and job creation targets are reached.

In 2015, the Company entered into an agreement with PNC, whereby the Company’s project finance subsidiaries may enter into sale-leaseback agreements for commissioned projects where we have entered into a PPA with the end-user of power and site host. Under the financing method of accounting for a sale-leaseback, the Company does not recognize as income any of the sale proceeds received from the lessor that contractually constitutes payment to acquire the assets subject to these arrangements. Instead, the sale proceeds received are accounted for as financing obligations. During 2016, three sales-leaseback transactions were completed under the PNC agreement, generating financing aggregating $41.6 million as of October 31, 2016.

In July 2014, the Company, through its wholly-owned subsidiary, entered into a Loan Agreement with NRG (the “Loan Agreement”). Pursuant to the Loan Agreement, NRG extended a $40.0 million revolving construction and term financing facility for the purpose of accelerating project development by the Company and its subsidiaries. We may draw on the facility to finance the construction of projects through the commercial operating date of the power plants. The interest rate is 8.5% per annum for construction-period financing and 8.0% thereafter. Fees that were paid to NRG for making the loan facility available and related legal fees incurred were capitalized and are being amortized straight-line over the life of the related loan agreement, which is five years. Borrowings under the Loan Agreement are secured by the related project assets. The loans may be repaid early should the projects be sold or refinanced at the option of the Company.

The Company has a long-term loan agreement with the Connecticut Clean Energy and Finance Investment Authority (CEFIA, now known as the CT Green Bank) totaling $5.9 million in support of the 2013 Bridgeport Fuel Cell Park project. The loan agreement carries an interest rate of 5.0%. Interest only payments commenced in January 2014 and principal payments will commence on the eighth anniversary of the project's provisional acceptance date, which is December 20, 2021, payable in forty-eight equal monthly installments. Outstanding amounts are secured by cash flows from the Bridgeport Fuel Cell Park service agreement.

We have a loan agreement with the Connecticut Development Authority to finance equipment purchases associated with manufacturing capacity expansion allowing for a maximum amount borrowed of $4.0 million. The interest rate is 5.0% and the loan is collateralized by the assets procured under this loan as well as $4.0 million of additional machinery and equipment. Repayment terms require interest and principal payments through May 2018.

During 2015, the Company had a revolving credit facility with JPMorgan Chase Bank, N.A. (the "Bank") for financing export receivables and was supported by the U.S. Import Export Bank. The credit facility expired on November 28, 2015 and the outstanding balance was paid back on November 24, 2015.

We lease computer equipment under master lease agreements. Lease payment terms are generally 36 months from the date of acceptance for leased equipment.
