Share-Based Compensation
Share-Based Compensation	Note 2 - Share-Based Compensation The Compensation Committee of the Board of Directors of the Company (the “Board”) grants stock options and restricted stock under the Company’s 2008 Long-Term Incentive Plan (as amended, the “2008 Plan”). Prior to an amendment to the 2008 Plan that became effective on October 15, 2015, the 2008 Plan provided that up to 407,143 shares of common stock could be delivered under the 2008 Plan to certain of the Company’s employees, consultants, and non-employee directors. As amended, the 2008 Plan provides for the issuance of up to 1,585,718 shares of common stock. In addition, the 2008 Plan provides for an automatic annual increase in the number of shares of common stock reserved under the 2008 Plan in an amount equal to 35,715 shares. As of June 30, 2016, there were 1,463,155 shares of common stock reserved for issuance under the 2008 Plan. During the first six months of 2016, options to purchase 100,000 shares were granted under the 2008 Plan, and options to purchase 1,248,155 shares were outstanding under the 2008 Plan as of June 30, 2016. All options granted under the 2008 Plan were granted at a price equal to or greater than the market price of the Company’s stock on the date of grant. Substantially all outstanding stock options under the 2008 Plan vest ratably over three years and expire 10 years from the date of grant. In addition to grants made under the 2008 Plan, the Company gave employees the right to purchase shares at a discount to the market price under the Company’s employee stock purchase plans. The employee stock purchase plans allow Company employees to purchase the Company’s common stock at a discount using payroll deductions and entitle employees in the United States to receive favorable tax treatment provided by the Internal Revenue Code of 1986, as amended. During the three months ended March 31, 2015, the Board adopted, and subsequently the stockholders approved, the Lime Energy Co. 2014 Employee Stock Purchase Plan (the “2014 ESPP”). The 2014 ESPP provided for two successive six-month offering periods commencing on July 1, 2014 and January 1, 2015, respectively. During the three months ended June 30, 2015, the Board adopted, and subsequently the Company’s stockholders approved, the Lime Energy Co. 2015 Employee Stock Purchase Plan (the “2015 ESPP”). The 2015 ESPP provided for the issuance of up to 100,000 shares of common stock in two successive six-month offering periods commencing on July 1, 2015 and January 1, 2016, respectively. During the three months ended June 30, 2016, the Board adopted, and subsequently the Company’s stockholders approved, the Lime Energy Co. 2016 Employee Stock Purchase Plan (the “2016 ESPP”). The 2016 ESPP provided for the issuance of up to 100,000 shares of common stock in two successive six-month offering periods commencing on July 1, 2016 and January 1, 2017, respectively. On June 30, 2016, the Board terminated the 2016 ESPP. The Board grants restricted stock to non-employee directors under the Company’s 2010 Non-Employee Directors Stock Plan (the “Directors’ Plan”). Restricted stock granted to date under the Directors’ Plan for Board service vest 50% upon grant and 50% on the first to occur of the first anniversary of the grant date, if the director is then still serving on the Board, or the director’s death, disability, or retirement. Restricted stock granted under the Directors’ Plan for committee service vest 50% upon grant and 50% on the first to occur of the first anniversary of the grant date, if the director is then still serving on the committee, or the director’s death, disability, or retirement. During the first six months of 2016, the Company granted 71,344 shares of restricted stock under the Directors’ Plan. As of June 30, 2016, there were 213,020 shares of common stock available for issuance under the Directors’ Plan. The Company accounts for employee share-based awards in accordance with Accounting Standards Codification (“ASC”) 718 — Compensation — Stock Compensation, which requires companies to measure the cost of employee service received in exchange for a share-based award based on the fair value of the award at the date of grant, with expense recognized over the requisite service period (generally equal to the vesting period of the grant).

Recent Accounting Pronouncements
Recent Accounting Pronouncements	Note 3 — Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13 “Financial Instruments—Credit losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. Topic 326 amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. The amendments affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The amendments in this update broaden the information that an entity must consider in developing its expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss, which will be more useful to users of the financial statements. The amendments in this update are effective for annual reporting periods beginning after December 15, 2019. The Company is currently evaluating the impact of adopting ASU 2016-13 on its consolidated financial statements and related disclosures. In March 2016, FASB issued ASU 2016-09, “Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. The areas for simplification in this update involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendments in this update are effective for annual reporting periods beginning after December 15, 2016. The Company is currently evaluating the impact of adopting ASU 2016-09 on its consolidated financial statements and related disclosures. In March 2016, FASB issued ASU 2016-06, “ Derivatives and Hedging (Topic 815): “Contingent Put and Call Options in Debt Instruments”. Topic 815 requires that embedded derivatives be separated from the host contract and accounted for separately as derivatives if certain criteria are met, including the “clearly and closely related” criterion. The amendments in this update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. The amendments apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The amendments in this update are effective for annual reporting periods beginning after December 15, 2016. The Company is currently evaluating the impact of adopting ASU 2016-06 on its consolidated financial statements and related disclosures. In February 2016, FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 will require organizations that lease assets—referred to as “lessees”—to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Under the new guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current GAAP—which requires only capital leases to be recognized on the balance sheet—the new ASU will require both types of leases to be recognized on the balance sheet. ASU 2016-02 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact of adopting ASU 2016-02 on its consolidated financial statements and related disclosures. In January 2016, FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 provides guidance concerning certain matters involving the recognition, measurement, and disclosure of financial assets and financial liabilities. The guidance does not alter the basic framework for classifying debt instruments held as financial assets. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is not permitted, with some exceptions. The adoption of ASU 2016-01 will not have a material impact on the Company’s consolidated financial statements and related disclosures. In November 2015, FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 simplifies the presentation of deferred income taxes and requires deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. ASU 2015-17 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. ASU 2015-17 may be applied either prospectively or retrospectively to all periods presented. The Company is currently evaluating the impact of adopting ASU 2015-17 on its consolidated financial statements and related disclosures. In April 2015, FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. FASB issued the ASU to simplify the presentation of debt issuance costs, and to align with other existing FASB guidance. ASU 2015-03 is effective for annual periods beginning after December 15, 2015, and interim periods within those annual periods. The adoption of this standard did not have a significant impact on the Company’s consolidated financial statements. In May 2014, FASB issued ASU 2014-09, “Revenue from Contracts With Customers.” ASU 2014-09 supersedes nearly all existing guidance on revenue recognition under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled for those goods or services using a defined five-step process. More judgment and estimates may be required to achieve this principle than under existing GAAP. ASU 2014-09 is effective for annual periods beginning after December 15, 2017, including interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect upon initial adoption recognized at the date of adoption which includes additional footnote disclosures. The Company is currently evaluating the impact of adopting ASU 2014-09 on its consolidated financial statements and has not yet determined the method of adoption.

Earnings Per Share
Earnings Per Share	Note 4 — Earnings Per Share The Company computes income or loss per share under ASC 260 “Earnings Per Share,” which requires presentation of two amounts: basic and diluted loss per common share. Basic loss per common share is computed by dividing income or loss available to common stockholders by the number of weighted average common shares outstanding, and includes all common stock issued. Diluted earnings include all common stock equivalents. The Company has not included the outstanding options or warrants as common stock equivalents in the computation of diluted loss per share for the three and six months ended June 30, 2016 and 2015, because the effect would be anti-dilutive. The following table sets forth the weighted average shares issuable upon exercise of outstanding options: Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Weighted average shares issuable upon exercise of outstanding options Weighted average shares issuable upon exercise of outstanding warrants — — Weighted average shares issuable upon conversion of convertible preferred stock — — Weighted average shares issuable upon conversion of convertible debt — — Total

Subordinated Convertible Term Notes	Note 6 — Subordinated Convertible Term Notes to Fund Acquisition The Company financed the purchase price of the acquisition of EnerPath (as described in Note 5 above) through the issuance of debt. The Company entered into a Note Purchase Agreement (the “Note Purchase Agreement”) with Bison Capital Partners IV, L.P. (“Bison”) on March 24, 2015, pursuant to which the Company issued a subordinated convertible note due March 24, 2020 (the “Bison Note”) in the principal amount of $11,750,000 (the “Note Issuance”). The proceeds from the sale of the Bison Note were used to finance the EnerPath acquisition and to pay $0.9 million of fees and expenses incurred in connection therewith, including fees and expenses incurred in connection with the Note Purchase Agreement, which were capitalized and included as a discount to long-term debt. As of the date the Bison Note was issued, Bison owned 10,000 shares of the Company’s Series C Convertible Preferred Stock (the “Series C Preferred Stock”) — which was, as of the date thereof, convertible into approximately 30% of the Company’s common stock — and was the Company’s single largest stockholder. Two members of the Board, Andreas Hildebrand and Peter Macdonald, are partners of an affiliate of Bison. As such, they recused themselves from the Board’s consideration of the Note Issuance. Based upon the initial conversion price of the Bison Note ($3.16), all or any portion of the principal amount of the Bison Note, plus, subject to the terms of the Bison Note, any accrued but unpaid interest, but not more than the principal amount of the Bison Note, may, at the election of the note holder, be converted into 3,718,354 shares of common stock after March 24, 2018 or the occurrence of a change of control of the Company, whichever occurs first. The conversion price is subject to anti-dilution adjustments in connection with stock splits and similar occurrences and certain other events set forth in the Bison Note, including future issuances of common stock or common stock equivalents at effective prices lower than the then-current conversion price. Due to the terms of the anti-dilution provision, the Company separated this conversion feature from the debt instrument and accounts for it as a derivative liability that must be carried at its estimated fair value with changes in fair value reflected in the Company’s unaudited Condensed Consolidated Statements of Operations. Upon issuance, the initial estimate of fair value was established as both a derivative liability and as a discount on the Bison Note. That discount, absent the amendments to the Bison Note described below, would have been amortized to interest expense over the term of the Bison Note. The Company determined the estimated fair value of the derivative liability to be $4.3 million and $6.7 million as of June 30, 2016 and December 31, 2015, respectively. The fair value of the derivative liability was determined using a binomial option pricing model with the following assumptions: a risk-free rate of 1.20%; expected volatility of 85%; a maturity date of March 24, 2020; probability factors regarding the Company’s ability to meet the EBITDA covenants in the Bison Note; and a 0% probability that a future financing transaction would reduce the conversion price. On March 31, 2015, the Company executed an amendment to the Bison Note (“Amendment No. 1”). Amendment No.1 provided that, should the Company fail to meet certain trailing EBITDA targets as of June 30, September 30 or December 31, 2015, then for each such quarter in which such EBITDA target was not met, an additional $1.0 million in interest would have accrued and been added to the note principal. On March 30, 2016, the Company entered into a second amendment to the Bison Note (“Amendment No. 2”). Amendment No. 2 revised the covenants related to minimum consolidated EBITDA for the four consecutive fiscal quarters ending March 31, June 30, September 30 and December 31, 2016. Pursuant to Amendment No. 2, if the Company fails to meet the specified trailing EBITDA targets for any of these quarters, then for each such quarter in which such EBITDA target is not met up to an additional $0.5 million in interest will accrue and be added to the note principal. As a result of Amendment No. 2, the Company’s failure to meet the specified trailing EBITDA targets for any of the four consecutive fiscal quarters ending March 31, June 30, September 30 and December 31, 2016 would not be an event of default under the Bison Note. Amendment No. 2 did not, however, revise the required minimum consolidated EBITDA targets for periods subsequent to December 31, 2016. Going forward, if the Company is unable to further amend the Bison Note or significantly improve its EBITDA, the Company’s consolidated EBITDA may not exceed the minimum consolidated EBITDA tests required by the Bison Note and, as a result, an event of default would exist under the Bison Note for which Bison could accelerate the Company’s repayment of the indebtedness. Pursuant to prevailing accounting guidance, Amendment No. 2, for accounting purposes, was treated as an extinguishment of the original amended note and the issuance of a new note, with the conversion derivative left intact and unchanged. Upon extinguishment, the net carrying amount of the extinguished note (including its principal amount and related discounts) of $7.4 million was written off and the fair value of the amended note was established, resulting in a net charge to earnings in the unaudited Condensed Consolidated Statement of Operations for the six months ended June 30, 2016 of $2.1 million. The fair value of the amended note was determined by reference to its probability weighted average expected cash flows discounted at an estimated market interest rate for a hypothetical similar non-convertible note issued by the Company. The March 30, 2016 carrying value of $9.5 million will incur interest charges at an effective interest rate required to result in the ultimate amount of cash flows needed to service the Bison Note. As of March 30, 2016, that effective interest rate was estimated at 26.4% but may change depending on actual cash requirements to service the Bison Note pursuant to the various interest payment alternatives described above. As of June 30, 2016, the Company was not in compliance with the revised covenants related to minimum consolidated EBITDA and, as a result, $0.5 million of interest was accrued and added to the note principal. As of June 30, 2016, $11.8 million of principal and accrued interest was outstanding under the Bison Note.

Sale of Series C Preferred Stock
Sale of Series C Preferred Stock	Note 7 — Sale of Series C Preferred Stock On December 23, 2014, the Company entered into a Preferred Stock Purchase Agreement with Bison, pursuant to which Bison purchased 10,000 shares of the Company’s Series C Preferred Stock at a price of $1,000 per share of Series C Preferred Stock. The shares of Series C Preferred Stock are entitled to an accruing dividend of 12.5% per annum of their base amount (subject to adjustments for stock splits, combinations and similar recapitalizations), payable every six months. The base amount is adjusted on each dividend payment date for the unpaid dividends accrued. The Company accrued dividends of $0.4 million and $0.7 million during the three months and six months ended June 30, 2016, respectively. The shares of Series C Preferred Stock may be converted, at any time, at the option of the holder, into shares of the Company’s common stock at a conversion price which was initially equal to $2.40 per share (the “Series C Conversion Price”). The Series C Conversion Price shall be proportionately adjusted for stock splits, combinations and similar recapitalizations, and shall be adjusted for future issuances of common stock. At any time after the fourth anniversary of the closing date, the Company shall have the right to redeem all, but not less than all, of the shares of Series C Preferred Stock for an amount equal to the original issue price of the shares plus all accrued but unpaid dividends, with such redemption to occur 30 days after the Company’s giving notice thereof to the holder(s) of the shares of Series C Preferred Stock. During such 30-day period, the holders of the Series C Preferred Stock may convert the Series C Preferred Stock to common stock in lieu of receiving the redemption payment. At any time after the fourth anniversary of the closing date, a holder of Series C Preferred Stock shall have the right to require the Company to redeem all or a portion of its Series C Preferred Stock for an amount equal to the original issue price of the shares plus all accrued but unpaid dividends. In the event the Company fails to make the required redemption payment by the date fixed for such payment, the dividend rate will increase to 15% per annum and increase by an additional 1% per annum each quarter until paid. In connection with the issuance of the Series C Preferred Stock, the Company, Bison, Richard Kiphart and The John Thomas Hurvis Revocable Trust entered into a Shareholder and Investor Rights Agreement dated as of December 23, 2014 (the “Shareholder Agreement”). Pursuant to the terms of the Shareholder Agreement, in the event the Company proposes to issue new securities (subject to certain exceptions), the Company must allow Bison to purchase a proportion of the new securities equal to the number of shares of common stock beneficially owned by Bison divided by the total number of shares of common stock then outstanding, on a fully-diluted basis. The Shareholder Agreement also provides Bison with operational consent rights and director appointment rights that apply so long as Bison holds at least five percent of the total voting power of the Company. The stockholders of the Company party to the Shareholder Agreement have agreed to vote in favor of Bison’s director appointees. The Shareholder Agreement entitles Bison to appoint one director to the Company’s Compensation Committee and any new board committee that is established, other than the Audit Committee or the Governance and Nominating Committee. It also entitles Bison to receive certain financial information. Bison may not, subject to certain exceptions in the Shareholder Agreement, acquire additional shares of common stock or seek to influence the management of the Company without the Company’s consent. Such restrictions will no longer apply upon certain changes of control of the Company. If, on the fifth anniversary of the closing date or any succeeding anniversary of such date, ten percent of the average daily trading volume of common stock is less than the number of shares of common stock beneficially owned by Bison divided by 240, then Bison may require the Company to initiate a sale process. Subject to the terms of the Shareholder Agreement, the stockholders of the Company party to the Shareholder Agreement have agreed to vote in favor of and otherwise support such a sale. If such a sale is not consummated within nine months, Bison shall have the right to require the Company to purchase, subject to the terms of the Shareholder Agreement, all or any portion of its Series C Preferred Stock or common stock into which such Series C Preferred Stock has converted, for a per share price generally equal to the average closing price of the Company’s common stock for the 60 trading days immediately preceding giving notice of exercise of such right. The Company incurred costs of approximately $0.6 million to issue the Series C Preferred Stock. These costs were recorded net of the proceeds of the Series C Preferred Stock. The Series C Preferred Stock is classified outside of permanent equity as the rights of redemption and the ability to initiate a sale are not solely within the control of the Company. On March 24, 2015, the Company amended and restated the Shareholder Agreement (as amended and restated, the “Amended and Restated Shareholder Agreement”) and that certain Registration Rights Agreement dated December 23, 2014 by and among the Company, Bison and certain other stockholders of the Company (as amended and restated, the “Amended and Restated Registration Rights Agreement”). Pursuant to the terms of the Amended and Restated Shareholder Agreement, in the event the Company proposes to issue new securities (subject to certain exceptions), the Company must allow Bison to purchase a proportion of the new securities equal to the number of shares of common stock beneficially owned by Bison (including the shares of common stock into which the Bison Note could convert) divided by the total number of shares of common stock outstanding on a fully-diluted basis. The operational consent rights and director appointment rights held by Bison under the Shareholder Agreement remain in the Amended and Restated Shareholder Agreement; provided, however, that, in the event Bison is no longer entitled to designate at least one director under the terms of the Series C Preferred Stock, Bison will be entitled under the Amended and Restated Shareholder Agreement to designate that number of directors that is consistent with its ownership of common stock (including shares of common stock that are convertible from the Series C Preferred Stock and the Bison Note, assuming the Bison Note was immediately convertible) if it holds at least five percent of the common stock (computed in the same fashion). Pursuant to the Amended and Restated Registration Rights Agreement, Bison is entitled to certain registration rights in connection with the common stock into which its shares of Series C Preferred Stock and the Bison Note may convert, including the right to demand the registration of such shares at any time after December 23, 2015 and rights to include such shares in other registration statements filed by the Company. Additionally, Mr. Kiphart and the John Thomas Hurvis Revocable Trust are entitled to include certain of their shares of common stock in a registration statement filed by the Company. The Company has agreed to indemnify the other parties to the Amended and Restated Registration Rights Agreement in connection with any claims related to their sale of securities under a registration statement, subject to certain exceptions.

Letter of Credit Agreement.
Letter of Credit Agreement	Note 8 — Letter of Credit Agreement On August 1, 2014, the Company entered into a Letter of Credit Agreement with Mr. Kiphart (the “LOC Agreement”), which replaced a previous letter of credit agreement the Company had entered into with Mr. Kiphart on December 7, 2012. Pursuant to the LOC Agreement, Mr. Kiphart agreed to cause, at the Company’s request, the issuance of one or more letters of credit (collectively, the “Kiphart Letter of Credit”) for the benefit of a surety, up to an aggregate amount of $1.3 million. The Kiphart Letter of Credit was used to guarantee certain obligations of the Company in connection with its performance under a contract between the Company and a utility customer. The Company agreed to pay Mr. Kiphart simple interest on the aggregate amount of the Kiphart Letter of Credit at a rate of six percent per annum. The Company accrued interest of approximately $19,000 during the three months ended March 31, 2015. As consideration for Mr. Kiphart’s obligations under the LOC Agreement, the Company issued to Mr. Kiphart warrants to purchase 50,000 shares of the Company’s common stock. The value of the warrants, which had been determined to be $0.1 million, was capitalized as deferred financing costs. In connection with the issuance of Series C Preferred Stock discussed in Note 7 - Sale of Series C Preferred Stock, the warrants were forfeited and deferred financing costs of $0.1 million were recorded to interest expense. In May 2015, the Company replaced the Kiphart Letter of Credit with restricted funds of the Company. The restriction on these funds was released in January 2016 as the Company entered into two letter of credit agreements with Heritage Bank of Commerce in December 2015 for letters of credit of $1.3 million and $0.1 million (the “Letters of Credit”) as discussed under Note 9 — Line of Credit — Heritage Bank of Commerce. The Letters of Credit are used to guarantee certain obligations of the Company in connection with its performance under contracts between the Company and two utility customers. The Letters of Credit reduce the Company’s borrowing base as calculated in the Company’s Line of Credit with Heritage Bank of Commerce as described in Note 9.

Line of Credit - Heritage Bank of Commerce	Note 9 — Line of Credit — Heritage Bank of Commerce On July 24, 2015, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Heritage Bank of Commerce (the “Bank”), whereby the Bank agreed to make available to the Company a secured credit facility (the “Credit Facility”) consisting of a $6.0 million revolving line of credit which the Company may draw upon from time to time, subject to the calculation and limitation of a borrowing base, for working capital and other general corporate purposes. As additional incentive to the Bank to enter into the Credit Facility and make available to the Company funds thereunder, the Company issued to the Bank a warrant to purchase shares of the Company’s common stock up to $60,000 in the aggregate. The line of credit, which matures on July 24, 2017, bears variable interest at the prime rate plus 1.00% and is collateralized by certain assets of the Company and its subsidiaries including their respective accounts receivable, certain deposit accounts, and intellectual property. On December 21, 2015, the Company entered into an amendment (the “First Amendment”) to the Loan Agreement with the Bank. The First Amendment established a sublimit of $2.0 million for Letters of Credit under the Credit Facility. Except as specifically amended and modified by the First Amendment, all other terms and conditions of the Loan Agreement remain in effect. In December 2015, the Company entered into two Letter of Credit agreements with Heritage Bank of Commerce for letters of credit of $1.3 million and $0.1 million. The Letters of Credit are used to guarantee certain obligations of the Company in connection with its performance under contracts between the Company and two utility customers. The Letters of Credit reduce the Company’s borrowing base as calculated under the Loan Agreement. The Loan Agreement requires the Company to comply with a number of conditions precedent that must be satisfied prior to any borrowing. In addition, the Company is required to remain compliant with certain customary representations and warranties and a number of affirmative and negative covenants. The occurrence of an event of default under the Loan Agreement may cause amounts outstanding during the event of default to accrue interest at a rate of 3.00% above the interest rate that would otherwise be applicable. On June 10, 2016, the Company entered into a further amendment (the “Second Amendment”) to the Loan Agreement with the Bank. The Second Amendment increased the Credit Facility to $10.0 million. The Second Amendment also extends the maturity date one year to July 24, 2018 and requires the Company to achieve revised rolling four-quarter EBITDA targets, measured as of the last day of each quarter, as follows: $2,179,000 for the quarter ended March 31, 2016; $2,006,000 for the quarter ended June 30, 2016; $2,437,000 for the quarter ending September 30, 2016; and $3,995,000 for the quarter ending December 31, 2016. The Company and the Bank agreed to negotiate and agree on EBITDA targets for 2017 by January 15, 2017, absent which all amounts then outstanding would be due and payable on March 31, 2017. Similarly, EBITDA targets for 2018 shall be set by January 15, 2018 or the amounts then outstanding shall become due and payable on March 31, 2018. Except as specifically amended and modified by the Second Amendment, all other terms and conditions of the Loan Agreement remain in effect. As of June 30, 2016, the Company was in compliance with its asset coverage ratio covenant but was not in compliance with its EBITDA covenant with the Bank. Which could impact its ability to draw down on the Credit Facility. Although no assurance can be given, the Company expects to receive a waiver from the Bank along with renegotiation of its covenant targets. As of June 30, 2016, the calculation of the borrowing base left approximately $5.9 million available to draw down for the Credit Facility. As of June 30, 2016, the Company has not drawn down on the Credit Facility. .

Legal Matters	Note 11 — Legal Matters SEC Investigation. In 2012, the SEC commenced an investigation with respect to certain of the Company’s revenue recognition practices and financial reporting. The Company has cooperated with the Staff of the Enforcement Division of the U.S. Securities and Exchange Commission (“SEC staff”) throughout the course of the investigation. During the second quarter of 2016, the Company reached an agreement in principle with the SEC staff to resolve the investigation. At this time the Company, in accordance with ASC 450, “Contingencies”, has recorded a $1.0 million charge to income, being the amount it believes is now probable will be paid. This charge is recorded in Other expenses in the Condensed Consolidated Statement of Operations. The SEC staff has not yet presented the proposed settlement to the Commission and no assurance can be given that the Commission will approve the proposed settlement or that the amount estimated will not change. Dressler v. Lime Energy, United States District Court for the District of New Jersey, Case 3:14-cv-07060-FLW-DEA. This purported “whistleblower” case was filed on November 10, 2014, alleging illegal retaliation by the Company for the plaintiff’s alleged disclosure of activity she believed violated the Securities Exchange Act of 1934, as amended. The plaintiff alleges that she made repeated disclosures to various individuals employed by the Company that certain accounting practices were improper and could lead to a restatement of financial statements. The plaintiff filed her complaint pursuant to the Sarbanes-Oxley Act of 2002 (18 U.S.C. §1514A), and the Dodd-Frank Wall Street Reform and Consumer Protection Act (15 U.S.C. §78u-6, et seq.). This case has been accepted for coverage under the Lime Energy Executive Protection Portfolio Policy. Although the Company believes the lawsuit has no merit, the court has denied the Company’s motion to dismiss the case. The Company can provide no assurances that this matter will be successfully resolved. As of the date of this report, a potential loss or a potential range of loss cannot be reasonably estimated.
