On May 7, 2018 (the “Closing Date”), Precision Engineered Products LLC, a Delaware limited liability company (the “Purchaser”) and wholly-owned subsidiary of NN, Inc., a Delaware corporation (the “Company”), completed its previously announced acquisition (the “Acquisition”) of all of the outstanding capital stock of PMG Intermediate Holding Corporation, a Delaware corporation (“PMG”), pursuant to that certain Stock Purchase Agreement, dated as of April 2, 2018 (the “Stock Purchase Agreement”), by and among Purchaser, PMG, Paragon Equity LLC, a Delaware limited liability company (the “Seller”) and, solely for the purposes of Article V and Article XI therein, the Company.

In connection with the Acquisition, on the Closing Date, the Company, certain Company subsidiaries named therein, SunTrust Bank, as Administrative Agent (“SunTrust”), SunTrust Robinson Humphrey, Inc. as Lead Arranger, and certain lenders named therein entered into that certain Amendment No. 4 to Amended and Restated Credit Agreement (the “Amendment”), which amended the Company’s existing senior secured amended and restated credit agreement, dated as of September 30, 2016, by and among the Company, SunTrust, as Administrative Agent, certain lenders from time to time party thereto, et al. The Amendment permits the Acquisition and the Company’s incurring secured second lien term loans in an aggregate amount not to exceed $200.0 million and adjusts certain covenants in connection therewith.

The foregoing summary is subject to, and qualified in its entirety by, the full text of the Amendment, which is filed herewith as Exhibit 10.1 and incorporated herein by reference.

Also in connection with the Acquisition, on the Closing Date, the Company, certain Company subsidiaries named therein, SunTrust, as Administrative Agent, SunTrust Robinson Humphrey, Inc. as Lead Arranger and Bookrunner, and the lenders named therein entered into a Second Lien Credit Agreement (the “Second Lien Credit Agreement”) pursuant to which SunTrust and the other lenders extended a $200.0 million secured second lien term loan facility (the “Second Lien Facility”). The Company utilized the net proceeds from the Second Lien Facility, together with cash on hand, to pay in part the Purchase Price (as defined below) and fees and expenses related thereto.

The following is a summary of the Second Lien Facility.

Interest. The interest rates applicable to borrowings under the Second Lien Facility are based on a fluctuating rate of interest measured by reference to either, at the Company’s option, (i) a base rate, plus an applicable margin, or (ii) the greater of the London Interbank Offered Rate (“LIBOR”) or 1.00%, plus an applicable margin. The initial applicable margin for all borrowings under the Second Lien Facility is 7.00% per annum with respect to base rate borrowings and 8.00% per annum with respect to LIBOR borrowings.

Prepayments. The Company may voluntarily prepay outstanding loans under the Second Lien Facility, in whole or in part without premium or penalty for a period of three months following the Closing Date or at any time following the second anniversary of the Closing Date. The Company may be subject to a prepayment penalty of 2% of the amount of such loans that it prepays more than three months after the Closing Date but prior to the first anniversary of the Closing Date. If the Company prepays any outstanding loans following the first anniversary of the Closing Date but prior to its second anniversary, the Company may be subject to a prepayment penalty of 1% of the amount prepaid. The Second Lien Credit Agreement requires the Company to prepay outstanding loans, subject to certain exceptions, with: (i) a variable percentage of excess cash flow; (ii) 100% of the net cash proceeds of non-ordinary course asset sales or other dispositions of property by the Company or any of its subsidiaries, and 100% of the

net cash proceeds from certain insurance and condemnation events with respect to the Company’s assets, subject to customary thresholds and reinvestment rights; (iii) 100% of the net cash proceeds from the issuance or incurrence of debt obligations for borrowed money not permitted by the Second Lien Credit Agreement by the Company or any of its subsidiaries; and (iv) 100% of the net cash proceeds from the issuance of equity after the Closing Date and prior to the third month anniversary of the Closing Date. In addition to other exceptions set forth in the Second Lien Credit Agreement, prepayments are not required to the extent of any required prepayments under the First Lien Credit Agreement, as defined in the Second Lien Credit Agreement.

Maturity. The Second Lien Facility matures on April 19, 2023.

Guarantee and Security. The Company’s obligations under the Second Lien Facility are guaranteed by the Company and each of the Company’s direct and indirect, existing and future material, domestic subsidiaries, subject to customary exceptions and limitations. The Second Lien Facility is secured by a perfected second priority lien over substantially all of the Company’s and each guarantor’s assets, subject to certain customary exceptions.

Covenants. The Second Lien Facility is subject to negative covenants that, among other things and subject to certain exceptions, limit the Company’s ability and the ability of its restricted subsidiaries to: (i) incur liens; (ii) incur indebtedness; (iii) make investments and acquisitions; (iv) merge, liquidate or dissolve; (v) sell assets, including capital stock of subsidiaries; (vi) pay dividends on capital stock or redeem, repurchase or retire capital stock; (vii) alter the Company’s business; (viii) engage in transactions with the Company’s affiliates; (ix) enter into burdensome agreements; (x) use proceeds from the Second Lien Facility; (xi) amend organizational documents; (xii) change accounting policies or reporting practices; (xiii) prepay or repurchase other indebtedness; and (xiv) perform other actions related to its subsidiaries with exceptions set forth in the Second Lien Credit Agreement.

Events of Default. The Second Lien Facility also contains certain customary events of default (including, among others, an event of default upon a change of control). If an event of default occurs and is not cured or waived, the lenders under the Second Lien Facility are entitled to take various actions, including the acceleration of amounts due under the Second Lien Facility and all actions permitted to be taken by a secured creditor.

The foregoing summary is subject to, and qualified in its entirety by, the full text of the Second Lien Credit Agreement, which is filed herewith as Exhibit 10.2 and incorporated herein by reference.
