THIS INSTRUMENT IS SUBJECT TO THE TERMS OF A SUBORDINATION AGREEMENT BY BDEWEES, INC. AND XGEN III, LTD. IN FAVOR OF WELLS FARGO BANK, NATIONAL ASSOCIATION, ACTING THROUGH ITS WELLS FARGO BUSINESS CREDIT OPERATING DIVISION, DATED AS OF NOVEMBER 30, 2011.

SECOND AMENDED AND RESTATED

PROMISSORY NOTE

(SECURED BY PERSONAL PROPERTY)

This Note amends and restates the original promissory note dated November 30, 2007, as amended and restated on December 1, 2010, in the original principal amount of $2,000,000.00 made by Magnetech Industrial Services, Inc., an Indiana corporation, and MISCOR Group, Ltd., an Indiana corporation, both with an address at 800 Nave Road SE, Massillon, Ohio 44646 (collectively “Borrowers”), and delivered to XGen III, Ltd., an Ohio limited liability company, (“Lender”) with an address at 3029 Prospect Ave, Cleveland, Ohio 44115.

PROMISE TO PAY. Borrowers, jointly and severally, promise to pay Lender, or order, in lawful money of the United States of America, the principal amount of Two Million Dollars ($2,000,000.00), together with interest on the unpaid principal balance from November 30, 2007, until paid in full.

PAYMENT. Borrowers will pay regular monthly payments of all accrued unpaid interest to date, with the first such payment beginning January 1, 2008, and with all subsequent interest payments to be due on the same day of each successive month thereafter.

Interest accruing on this Note for any given period is computed on the basis of a 360-day year; that is, by dividing the annual interest rate by a year of 360-days, multiplied by the outstanding principal balance, multiplied by the actual number of days within the given period (not to exceed the number of days in which the amount of the outstanding principal balance remained the same). Borrowers will pay Lender at 3029 Prospect Ave, Cleveland, Ohio 44115 or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE. (a) Beginning on the day after the Second Amendment Date through June 30, 2012, the interest rate on this Note shall be the Index Rate plus six percentage points, but shall not be less than ten and one half of one percent (10 ¹/2%) per annum without compounding, and (b) commencing July 1, 2012 and thereafter, the interest rate on this Note shall be the Index Rate plus nine percentage points, but shall not be less than nineteen percent (19%) per annum without compounding. Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.

“Index Rate” means the prime rate published by The Wall Street Journal, and if that rate is not available for any reason, then the prime rate announced by Charter One Bank, Cleveland, Ohio (“Bank”) from time to time which is not necessarily the lowest rate charged by Bank on its loans and is set by Bank in its sole discretion. If the Index Rate becomes unavailable during the term of this Note, Lender may designate a substitute index from a comparable financial institution in the Cleveland, Ohio, area after notifying Borrowers.

PREPAYMENT. Borrowers may pay without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrowers of Borrowers’ obligations to continue to make the monthly payments described above. Rather, early payments will reduce the principal balance due. Borrowers agree not to send Lender payments marked “paid in full”, “without recourse”, or similar language. If Borrowers send such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrowers will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument which indicates that the payment constitutes “payment in full” of the amount owed or which is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: XGen III, Ltd., 3029 Prospect Ave, Cleveland, Ohio 44115.

LATE CHARGE. If a payment is 7 days or more late, Borrowers will be charged 10.000% of the unpaid portion of the regularly scheduled payment.

INTEREST AFTER DEFAULT. Upon an Event of Default, including (a) failure to make any principal payments pursuant to that certain Loan Extension and Modification Agreement, dated November 30, 2011, among Borrowers and Lender (the “Modification Agreement”), and (b) timely payment upon final maturity, Lender, at its option, may, if permitted under applicable law, increase the variable interest rate on this Note to five (5) percentage points over the then applicable interest rate. The interest rate will not exceed the maximum rate permitted by applicable law.

DEFAULT. Each of the following shall constitute an event of default (“Event of Default”) under this Note:

Payment Default. Borrowers fail to make any payment in full when due under this Note.

Other Defaults. Borrowers fail to comply with or to perform any other term, obligation, covenant or condition contained in this Note or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and one or both Borrowers (including without limitation the Modification Agreement) or on any agreement by and between Lender and 3-D Service, Ltd (“3-D”) or contained in any note by Borrowers to BDeWees, Inc., an Ohio corporation (“BDeWees”) or in any agreement between BDeWees and any one or both Borrowers or in any agreement between BDeWees and 3-D.

Cure Provisions. If any default, other than a default in payment is curable, it may be cured (and no event of default will have occurred) if Borrowers, after receiving written notice from Lender demanding cure of such default cure the default within thirty (30) days.

LENDER’S RIGHTS. Upon an Event of Default, Lender may declare the entire unpaid principal balance on this Note and all accrued unpaid interest immediately due and payable, and then Borrowers will pay that amount. Lender’s rights are subject to the provisions of an Intercreditor Agreement dated November 30, 2007, by and between Lender and BDeWees.

SECURITY. This Note is secured in accordance with the provisions of a security agreement between Lender and 3-D dated November 30, 2007, as amended, by 3-D’s successor in interest by merger, Magnetech Industrial Services, Inc. (“Magnetech”), as well as in accordance with the provisions of other security agreements between Lender and Magnetech now or hereafter entered into.

ATTORNEYS’ FEES; EXPENSES. Lender may hire or pay someone else to help collect this Note if Borrowers do not pay. Borrowers will pay Lender the costs for collection efforts. This includes, subject to any limits under applicable law, Lender’s attorneys’ fees and Lender’s legal expenses, whether or not there is a lawsuit, including attorneys’ fees, expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), and appeals. If not prohibited by applicable law, Borrowers also will pay any court costs, in addition to all other sums provided by law. All of the amounts set forth in this paragraph shall become part of the principal amount due and owing under this Note, and as such shall bear interest hereunder until paid in full. Nevertheless, if Borrowers are prevailing parties in any claim or lawsuit between Borrowers and Lender regarding this Note, then Borrowers shall not owe Lender any fees or expenses and, instead, Lender shall reimburse Borrowers for the attorneys fees and expenses they incur in such action.

Any such excess interest or unauthorized fee shall, instead of anything stated to the contrary, be applied first to reduce the principal balance of this Note, and when the principal has been paid in full, be refunded to Borrowers.

The records of Lender shall constitute presumptive evidence of the amounts owing under this Note. Upon any change in the terms of this Note, and unless otherwise expressly stated in writing, no party who signs this Note, whether as maker, guarantor, accommodation maker or endorser, shall be released from liability. All such parties agree that Lender may renew or extend (repeatedly and for any length of time) this Note or release any party or guarantor collateral; or impair, fail to realize upon or perfect Lender’s security interest in the collateral; and take any other action deemed necessary by Lender without the consent of or notice to anyone. Borrowers, and all endorsers of this Note, hereby waive all acts on the part of the Lender or holder of this Note required in fixing Borrowers’ liability hereunder, including, without limitation, presentment, demand, notice of dishonor, protest, and notice of non-payment and protest, and any other notice whatsoever, and further waive any default by reason of extension of time for payment or any other indulgence or forbearance granted to Borrowers or endorser hereof.

Borrowers hereby acknowledge that the proceeds of this Note have been used for business purposes and not for consumer, family or household purposes.

Stay of execution and all exemptions are hereby waived. If any obligation is referred to an attorney for collection, and the payment is obtained without the entry of a judgment, the obligors shall pay to the holder of such obligation its attorneys’ fees.
