EXHIBIT 4.1 PROMISSORY NOTE $12,500,000.00 January 3, 2006 FOR VALUE RECEIVED, Hallmark Financial Services, Inc., a Nevada corporation ("Maker"), promises to pay to the order of Newcastle Partners, L.P., a Texas limited partnership ("Payee"), the sum of TWELVE MILLION FIVE HUNDRED THOUSAND AND NO/100 DOLLARS ($12,500,000.00), together with per annum interest on the unpaid balance hereof from time to time remaining unpaid, at a rate equal to the lesser of (i) ten percent (10%) per annum, compounded monthly, and (ii) the maximum rate allowed under applicable law (the "Maximum Rate"), both principal and interest being payable at 300 Crescent Court, Suite 1110, Dallas, Texas 75201, or at such other place as Payee may, from time to time, designate in writing. Accrued and unpaid interest under this Promissory Note (this "Note") shall be due and payable on the first business day of each month. The unpaid principal balance on this Note together with all accrued and unpaid interest is due and payable on demand at any time after June 30, 2006. All past due principal and accrued interest on this Note shall bear interest from the date such amount is due until paid at the Maximum Rate. Maker agrees to use the proceeds of this Note to fund the acquisition of Aerospace Holdings, LLL pursuant to that certain Purchase Agreement dated December 12, 2005, by and among Hallmark Financial Services, Inc. and Donnell Children Revocable Trust and Curtis R. Donnell. 1. Prepayments. Maker shall have the right to prepay the unpaid principal balance hereof in part or in its entirety. In the event of a prepayment, there shall be no penalty or premium due. Any prepayment, whether in whole or in part, shall be applied first to accrued and unpaid interest and then to principal, and interest shall immediately cease to run on any amount of the principal so prepaid. 2. Default; Acceleration. At Payee's sole option, the entire unpaid principal balance of, and all accrued and unpaid interest on, this Note shall immediately be due and payable upon the occurrence of any of the following: (a) failure by Maker to pay any principal amount when due; (b) the occurrence of a default under any of Maker's other material loan obligations, (c) commencement of a voluntary case against Maker under Title 11 of the United States Code; or (d) the filing of an answer or other pleading admitting or failing to deny the material allegations of a petition filed against Maker commencing an involuntary case under said Title 11 or failure to timely controvert the material allegations of such petition; provided that, the failure by Maker to make an interest payment (other than an interest payment due to acceleration of amounts due under this Note) shall not constitute a default under this Note. 3. Cumulative Rights. No delay on the part of Payee or any other holder of this Note in the exercise of any power or right under this Note or under any other instrument executed pursuant hereto shall operate as a waiver thereof, nor shall a single or partial exercise of any power or right preclude other or further exercise thereof or the exercise of any other power or right. 4. Waiver. Except as expressly otherwise provided for herein, Maker and all endorsers of this Note waive demand, presentment, protest, notice of dishonor, notice of nonpayment, notice of intention to accelerate, notice of acceleration, notice of protest and any and all lack of diligence or delay in collection or the filing of suit hereon which may occur, and agree to all extensions and partial payments, before or after maturity, without prejudice to the holder hereof. 5. Attorneys' Fees and Costs. In the event that hereafter this Note is placed in the hands of an attorney for collection, or in the event that this Note is collected in whole or in part through legal proceedings of any nature, then and in any such case, there shall be added to the unpaid principal balance hereof all reasonable costs of collection, including but not limited to reasonable attorneys' fees, on account of such collection, whether or not suit is filed. 6. Governing Law. This Note shall be construed in accordance with the laws of the State of Texas. 7. Headings. The headings of the sections of this Note are inserted for convenience only and shall not be deemed to constitute a part hereof. 8. Usury. All agreements between Maker and Payee or any other holder of this Note, whether now existing or hereafter arising and whether written or oral, are expressly limited so that in no contingency or event whatsoever, whether by acceleration of this Note or otherwise, shall the amount paid, or agreed to be paid, to Payee or any other holder hereof, for the use, forbearance or detention of the money to be loaned hereunder or otherwise, exceed the Maximum Rate. If from any circumstances whatsoever fulfillment of any provision of this Note or of any other document evidencing, securing or pertaining to the indebtedness evidenced hereby, at the time performance of such provision shall be due, shall involve transcending the Maximum Rate, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstances Payee or any other holder of this Note shall ever receive as interest under this Note or any other document evidencing, securing or pertaining to the indebtedness evidenced hereby or otherwise an amount that would exceed the Maximum Rate, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing under this Note or on account of any other indebtedness of Maker to Payee or such holder hereof relating to this Note, and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal of this Note and such other indebtedness, such excess shall be refunded to Maker. In determining whether or not the interest paid or payable with respect to any indebtedness of Maker to Payee or any other holder hereof, under any specific contingency, exceeds the Maximum Rate, Maker and Payee or any other holder hereof shall, to the maximum extent permitted by applicable law: (a) characterize any nonprincipal payment as an expense, fee or premium rather than as interest; (b) exclude voluntary prepayments and the effects thereof; (c) amortize, prorate, allocate and spread the total amount of interest throughout the full term of such indebtedness so that the actual rate of interest on account of such indebtedness is uniform throughout the term thereof; and/or (d) allocate interest between portions of such indebtedness, to the end that no such portion shall bear interest at a rate greater than that the Maximum Rate. The terms and provisions of this paragraph shall control and supersede every other conflicting provision of all agreements between Maker and Payee or any other holder hereof. 9. Notices. All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given when personally delivered, transferred via facsimile or mailed, via certified or registered mail, as follows: if to Maker: Hallmark Financial Services, Inc. 777 Main Street Suite 1000 Fort Worth, Texas 76102 Fax No.: (817) 348-1815 Attention: Mark J.
