ITEM 1.01 Entry into a Material Definitive Agreement.

On August 7, 2012, Ubiquiti Networks, Inc., a Delaware corporation (the “Company”), entered into a Loan and Security Agreement (the “Loan Agreement”) by and among the Company, the lenders from time to time party thereto, U.S. Bank, as syndication agent , and East West Bank, as administrative agent.

The Loan Agreement provides for (i) a $50,000,000 revolving credit facility, with a $5,000,000 sublimit for the issuance of letters of credit and a $5,000,000 sublimit for the making of swingline loan advances (the “Revolving Credit Facility”), and (ii) a $50,000,000 term loan facility (the “Term Loan Facility”). The Company may request borrowings under the Revolving Credit Facility until August 7, 2015. On August 7, 2012, the Company borrowed $50,000,000 of term loans under the Term Loan Facility.

The loans bear interest, at the Company’s option, at the base rate plus a spread of 1.25% to 1.75% or an adjusted LIBOR rate (based, at the Company’s election, on a period of 30, 60, or 90 days) plus a spread of 2.25% to 2.75%, in each case with such spread being determined based on the debt service coverage ratio for the last fiscal quarter. The base rate means the highest of East West Bank’s prime rate, the federal funds rate plus a margin equal to 0.50%, or the adjusted LIBOR rate for a period of 30, 60, or 90 days plus a margin equal to 1.00%. The Company is also obligated to pay other customary closing fees, arrangement fees, administration fees, commitment fees and letter of credit fees for a credit facility of this size and type.

Interest is due and payable in arrears monthly in the case of loans bearing interest at the base rate and at the end of an interest period (or quarterly in the case of loans with interest periods greater than three months) in the case of loans bearing interest at the adjusted LIBOR rate. Principal payments under the Term Loan Facility will be made in quarterly installments, each such quarterly installment shall be equal to $1,250,000 until August 7, 2014, then equal to $1,875,000 until August 7, 2015, and then equal to $2,500,000 until August 7, 2017, subject to adjustment as a result of any prepayments, with the remaining outstanding principal balance and all accrued and unpaid interest due on August 7, 2017. All outstanding loans under the Revolving Credit Facility, together with all accrued and unpaid interest, are due on August 7, 2015.

The Company may prepay the loans, in whole or in part, at any time without premium or penalty, subject to certain conditions including minimum amounts and reimbursement of certain costs in the case of prepayments of LIBOR loans. In addition, the Company is required to prepay the loan under the Term Loan Facility with the proceeds from certain financing transactions or asset sales (subject, in the case of asset sales, to reinvestment rights) and with 25.0% of the Company’s excess cash flow, as determined after each fiscal year and in accordance with the Loan Agreement, provided that the Company shall not be required to prepay the loan out of its excess cash flow if its leverage ratio is greater than 1.50:1.00 on the last day of such fiscal year.

All of the obligations under the Loan Agreement are secured by substantially all of the Company’s assets, including all of the capital stock of the Company’s future domestic subsidiaries and 65% of the capital stock of the Company’s existing and future foreign subsidiaries, but excluding the Company’s intellectual property. All of the Company’s future domestic subsidiaries are required to guaranty the obligations under the Loan Agreement. Such guarantees by future subsidiaries will be secured by substantially all of the property of such subsidiaries, excluding intellectual property.

The Loan Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries’ ability to, among other things, incur indebtedness,

grant liens, merge or consolidate, dispose of assets, pay dividends or make distributions, repurchase stock, make investments, make acquisitions, prepay certain indebtedness, change the nature of its business, enter into certain transactions with affiliates, enter into restrictive agreements, and make capital expenditures, in each case subject to customary exceptions for a credit facility of this size and type. The Company is also required to maintain compliance with a debt service coverage ratio, a leverage ratio, and a minimum level of liquidity.

The Loan Agreement includes customary events of default that, include among other things, non-payment defaults, defaults due to the inaccuracy of representations and warranties, covenant defaults, cross default to material indebtedness, bankruptcy and insolvency defaults, material judgment defaults, defaults due to the unenforceability of a guaranty, and defaults due to circumstances that have or could have a material adverse effect. The occurrence of an event of default could result in the acceleration of the obligations under the Loan Agreement. During the existence of an event of default, interest on the obligations under the Loan Agreement could be increased by 2.00% above the otherwise applicable interest rate.

A copy of the Loan Agreement is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference herein. The above description is qualified in its entirety by reference to the exhibit.
