INTEREST RATE PROVISIONS

Section 3.1. Interest Rate Determination. The Loan shall bear interest on the unpaid principal amount thereof from time to time outstanding, until maturity, at a rate per annum (calculated based on a year of 360 days in each case for the actual days elapsed) as follows:

(a) The principal balance of the Loan from time to time outstanding shall bear interest at an annual rate equal to the lesser of (i) with respect to any LIBOR Rate Portion, the Adjusted LIBOR Rate, and with respect to any Base Rate Portion, the Base Rate, as the case may be, with respect thereto or (ii) the Highest Lawful Rate, from the day of Advance to, but not including, (y) with respect to any Base Rate Portion, the Maturity Date and (z) with respect to any LIBOR Rate Portion, the Expiration Date of the Rate Period then in effect with respect thereto. Notwithstanding the foregoing, at no time shall the principal balance of the Loan from time to time outstanding shall bear interest at an annual rate equal less than three and one-quarter of one percent (3.25%).

(b) So long as no Default or Event of Default has occurred and is continuing, Borrower may at any time prior to the applicable Maturity Date (y) change the interest rates to apply to all or any portion of the Loan or (z) elect to continue all or any part of the outstanding principal balance of any LIBOR Rate Portion as portions of such Type by giving Lender an irrevocable written notice in the form of Exhibit C hereto (the “Notice of Rate Change/Continuation”) specifying (i) the date on which the applicable LIBOR Rate Portion or Base Rate Portion was made; (ii) the interest rate then applicable to such LIBOR Rate Portion or Base Rate Portion; (iii) with respect to any LIBOR Rate Portions, the Rate Period then applicable to each such LIBOR Rate Portion; (iv) the principal amount of such LIBOR Rate Portion to remain outstanding; and (v) the requested effective date of the rate change or continuation (the “Conversion/Continuation Date”). In the case of the conversion of all or any part of any Base Rate Portion into a LIBOR Rate Portion or the continuation of any LIBOR Rate Portion, (x) such notice must be received by Lender at least three (3) full Business Days prior to the Conversion/Continuation Date, and otherwise at least one (1) full Business Day prior thereto, and (y) in either case such LIBOR Rate Portion shall be in an aggregate principal amount greater than or equal to $1,000,000 or in an integral multiple of $100,000 in excess thereof. Each rate so specified shall become effective on the Conversion/Continuation Date and remain in effect until the expiration of the applicable Rate Period specified in such Notice of Rate Change/Continuation. Each Notice of Rate Change/Continuation shall be irrevocable.

(c) If Borrower shall fail to choose, as provided in subsection (b) above, the rate of interest to become effective with respect to any LIBOR Rate Portions upon the Expiration Date of the Rate Period with respect thereto, such portion of the Loan shall

THIRD AMENDED AND RESTATED CREDIT AGREEMENT — TYLER TECHNOLOGIES, INC.

Page 16

bear interest at the Base Rate on and after such Expiration Date until Borrower shall have so chosen a different rate.

(d) Nothing contained herein shall authorize Borrower (i) to convert any Base Rate Portion into or continue any LIBOR Rate Portion as a LIBOR Rate Portion unless the Expiration Date of the Rate Period for the new LIBOR Rate Portion occurs on or before the Maturity Date, (ii) to continue or change the interest rates applicable to any LIBOR Rate Portions prior to the Expiration Date of the Rate Period with respect thereto, or (iii) to convert any Base Rate Portion into a LIBOR Rate Portion or to continue any LIBOR Rate Portion if a Default or an Event of Default has occurred and is continuing.

(e) Notwithstanding anything set forth herein to the contrary (other than Section 11.12), if an Event of Default has occurred and is continuing the Loan shall bear interest at a rate per annum which shall be equal to the lesser of (i) 3% above the Base Rate or (ii) the Highest Lawful Rate, which interest shall be due and payable on demand.

Section 3.2. Additional Interest Rate Provisions.

(a) Anything in this Agreement to the contrary notwithstanding, if at any time Lender determines (which determination shall be conclusive absent manifest error) that the introduction of or any change in any Governmental Regulation by any Governmental Authority charged with the interpretation or administration thereof shall make it unlawful for Lender to maintain or fund any LIBOR Rate Portion or to convert any Base Rate Portion into, or to continue, any LIBOR Rate Portion hereunder, Lender shall promptly give notice thereof to Borrower. With respect to any LIBOR Rate Portion which is outstanding when Lender so notifies Borrower, upon such date as shall be specified in such notice, the Rate Period shall end and the lesser of (i) the Base Rate or (ii) the Highest Lawful Rate shall commence to apply in lieu of the Adjusted LIBOR Rate in respect of such portion of the Loan. At least five (5) Business Days after such specified date, Borrower shall pay to Lender (y) accrued and unpaid interest on each affected LIBOR Rate Portion at the Adjusted LIBOR Rate in effect at the time of such notice to but not including such specified date plus (z) such amount or amounts (to the extent that such amount or amounts would not be usurious under applicable Governmental Regulation) as may be necessary to compensate Lender for any costs and losses incurred by it, but otherwise without penalty. If notice has been given by Lender pursuant to the foregoing provisions of this Section 3.2, then, unless and until the circumstances giving rise to such notice no longer apply, such Adjusted LIBOR Rate shall not again apply to any portion of the Loan and the obligation of Lender to convert any portion of the Loan into, or to continue, any LIBOR Rate Portion as, a LIBOR Rate Portion shall be suspended.

(b) Subject to Section 11.12 hereof, Borrower will indemnify Lender against, and reimburse Lender on demand for, any loss, cost or expense incurred or sustained by Lender (including, without limitation, any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by Lender to fund or maintain any LIBOR Rate Portion to Borrower ) as a result of (i) any Additional Costs incurred by Lender; (ii) any payment, prepayment or repayment (whether authorized or

THIRD AMENDED AND RESTATED CREDIT AGREEMENT — TYLER TECHNOLOGIES, INC.

Page 17

required hereunder or otherwise) of all or a portion of any LIBOR Rate Portion on a day other than the last day of a Rate Period for such LIBOR Rate Portion; (iii) any payment or prepayment (whether required hereunder or otherwise) of any LIBOR Rate Portion made after the delivery of a Notice of Borrowing or a Notice of Rate Change/Continuation, as the case may be, but before the applicable Borrowing Date or a Conversion/Continuation Date, as the case may be, if such payment or prepayment prevents the proposed borrowing from becoming fully effective; or (iv) after receipt by Lender of a Notice of Borrowing or a Notice of Rate Change/Continuation, as the case may be, the failure of any LIBOR Rate Portion to be made or effected by Lender due to any condition precedent to a borrowing not being satisfied by Borrower or due to any other action or inaction of Borrower.

(c) The agreements contained in Sections 3.2(a) and 3.2(b) shall survive the termination of this Agreement and the payment in full of the Note and all other amounts payable hereunder.

Neither execution or delivery by Borrower of any Loan Document nor the fulfillment of or compliance with its terms and provisions will (i) violate any Governmental Requirement of any Governmental Authority or the basic organizational documents of such Person or (ii) conflict with or result in a breach of the terms, conditions or provisions of, or cause a default under, any material agreement, instrument, franchise, license or concession to which such Person is a party or bound.

They are in proper legal form for prompt enforcement and they are Borrower’s valid and legally binding obligations enforceable in accordance with their terms, except as limited by applicable bankruptcy, insolvency, fraudulent transfer, fraudulent conveyance, reorganization, moratorium, or other similar laws at the time in effect affecting the rights of creditors generally. Borrower’s obligations under the Loan Documents rank and will rank at least equal in priority of payment with all of Borrower’s other debt.

Section 6.11. Margin Regulations. None of the proceeds of the Loan will be used for the purpose of purchasing or carrying, directly or indirectly, any margin stock or for any other purpose which would make such credit a “purpose credit” within the meaning of Regulation U of the Board of Governors of the Federal Reserve System.

Section 11.12. Interest. All agreements between Borrower and Lender, whether now existing or hereafter arising and whether written or oral, are hereby expressly limited so that in no contingency or event whatsoever, whether by reason of demand being made on the Note or otherwise, shall the amount contracted for, charged, reserved or received by Lender for the use, forbearance, or detention of the money to be loaned under this Agreement or otherwise or for the payment or performance of any covenant or obligation contained herein or in any other Loan Document exceed the Highest Lawful Rate. If, as a result of any circumstances whatsoever, fulfillment by Borrower of any provision hereof or of any of such documents, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by applicable usury law or result in Lender having or being deemed to have contracted for, charged, reserved or received interest (or amounts deemed to be interest) in excess of the maximum lawful rate or amount of interest allowed by applicable law to be so contracted for, charged, reserved or received by Lender, then, ipso facto, the obligation to be fulfilled by Borrower shall be reduced to the limit of such validity, and if, from any such circumstance, Lender shall ever receive interest or anything which might be deemed interest under applicable law which would exceed the Highest Lawful Rate, such amount which would be excessive interest shall be refunded to Borrower, or, to the extent (i) permitted by applicable law and (ii) such excessive interest does not exceed the unpaid principal balance of the Note and the amounts owing on other Obligations of Borrower to Lender under any Loan Document, applied to the reduction of the principal amount owing on account of the Note or the amounts owing on other Obligations of Borrower to Lender under any Loan Document and not to the payment of interest. All sums paid or agreed to be paid to Lender for the use, forbearance, or detention of the indebtedness of Borrower to Lender shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full term of such indebtedness until payment in full of the principal thereof (including the period of any renewal or extension thereof) so that the interest on account of such indebtedness shall not exceed the Highest Lawful Rate. The terms and provisions of this Section 11.12 shall control and supersede every other provision hereof and of all other agreements between Borrower and Lender. Borrower and Lender agree that Chapter 15 of the Texas Credit Code shall not apply to this Agreement, the Note, the Loan or the Commitment.

To the extent any payments on the Obligations or proceeds of any Collateral or the proceeds of such enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other Person under any debtor relief Law, then to the extent of such recovery, the Obligations or part thereof originally intended to be satisfied, and all rights and remedies therefor, shall be revived and shall continue in full force and effect, and Lender’s rights, powers and remedies under this Agreement and each other Loan Document shall continue in full force and effect, as if such payment had not been made or such enforcement or setoff had not occurred. In such event, each Loan Document shall be automatically reinstated and Borrower and each Subsidiary shall take such action as may be reasonably requested by Lender to effect such reinstatement.

Section 11.15. Amendments, Etc. No amendment or waiver of any provision of this Agreement, the Note or any other Loan Document, nor consent to any departure by Borrower or any Subsidiary herefrom or therefrom, shall in any event be effective unless the same shall be in writing and signed by Borrower and/or the applicable Subsidiary, as to amendments, and by Lender in all cases, and then, in any case, such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

Section 11.16. Relationship of the Parties. This Agreement provides for the making of a loan by Lender, in its capacity as a lender, to Borrower, in its capacity as a borrower, and for the payment of interest and repayment of principal by Borrower to Lender.

The provisions herein for compliance with financial, environmental, and other covenants, delivery of financial, environmental and other reports, and financial, environmental and other inspections, investigations, audits, examinations or tests are intended solely for the benefit of Lender to protect its interests as a lender in assuring payments of interest and repayment of principal and nothing contained in this Agreement or any other Loan Document shall be construed as permitting or obligating Lender to act as financial or business advisors or consultants to Borrower or any Subsidiary, as permitting or obligating Lender to control Borrower or any Subsidiary or to conduct or operate Borrower’s or any Subsidiary’s

AMENDED AND RESTATED PROMISSORY NOTE
(Revolving Line of Credit)



$25,000,000	Dallas, Texas	October 19, 2009

FOR VALUE RECEIVED, the undersigned, TYLER TECHNOLOGIES, INC., a Delaware corporation (the “Undersigned”), promises to pay to the order of BANK OF TEXAS, N.A., a national banking association, and any successors and assigns (the “Payee”), at ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, the principal sum of Twenty Five Million and no/100 Dollars ($25,000,000) (or the unpaid balance of all principal advanced under this Note, if that amount is less) together with interest on the unpaid principal balance of this Note from day to day outstanding, as hereinafter provided. All capitalized terms herein, unless otherwise defined, shall have the same definitions as those found in that certain Third Amended and Restated Credit Agreement by and between the Undersigned and Payee dated of even date herewith, as amended on the date hereof (as amended, the “Credit Agreement”). This Note amends and restates in its entirety that certain Promissory Note (Letter of Credit Facility) (the “Existing Note”) dated October 20, 2008, executed by the Undersigned, payable to Bank of Texas, N.A. in the principal amount of $25,000,000.00. All Liens securing the Existing Note are renewed and continued (and are not extinguished hereby) and secure this Note.

This Note shall evidence the Undersigned’s indebtedness to Payee for Payee’s portion of the Revolving Commitment, and advances made thereunder.

The Loan shall bear interest on the unpaid principal amount thereof from time to time outstanding, until maturity, at the interest rates as provided in, and pursuant to the terms of, the Credit Agreement.

Interest and principal on this Note shall be due and payable as provided in the Credit Agreement. The final principal payment and any unpaid interest owing hereunder shall be due and payable in full on the Maturity Date. The principal balance hereof may be, and shall be required to be, prepaid as provided in the Credit Agreement.

This Note is a revolving promissory note; therefore, amounts advanced hereunder may be repaid, readvanced and repaid pursuant to the terms set forth in the Credit Agreement.

At the option of the holder of this Note the entire principal balance and accrued interest owing hereon shall become due and payable without further demand upon the occurrence at any time of any Event of Default under the Credit Agreement.

THIRD AMENDED AND RESTATED CREDIT AGREEMENT — EXHIBIT A-1

kind, filing of suit and diligence in collecting this Note or enforcing any of the security herefor, and consents to all extensions which from time to time may be granted by the holder hereof and to all partial payments hereon, whether before or after maturity.

If this Note is not paid when due, whether at maturity or by acceleration or otherwise, or if it is collected through a bankruptcy, probate or other judicial or administrative proceeding, whether before or after maturity, the Undersigned agrees to pay all reasonable costs of collection, including, but not limited to, reasonable attorneys’ fees, incurred by the holder hereof.

Any provisions herein, or in any other document executed in connection herewith, or in any other agreement or commitment, whether written or oral, expressed or implied, to the contrary notwithstanding, the holder hereof shall in no event charge or be entitled to receive or collect, nor shall or may amounts received hereunder be credited, so that the holder hereof shall be paid, as interest, a sum greater than the maximum permitted by applicable law to be charged to the person, partnership, firm or corporation primarily obligated to pay this Note. If any construction of this Note, or any and all other papers, agreements or commitments, indicates a different right given to the holder hereof to ask for, demand or receive any larger sum as interest, such is a mistake in calculation or wording, which this clause shall override and control; it being the intention of the parties that this Note and all other instruments executed in connection herewith shall in all things comply with applicable law, and proper adjustment shall automatically be made accordingly. In the event the holder hereof ever receives, collects or applies as interest, any sum in excess of the maximum permitted by applicable law, such excess amount shall be applied to the reduction of the unpaid principal balance of this Note, in the inverse order of maturity, and not to interest, and if this Note is paid in full, any remaining excess shall be refunded to the Undersigned. In determining whether or not the interest paid or payable, under any specific contingency, exceeds the maximum permitted by applicable law, the Undersigned and the holder hereof shall, to the maximum extent permitted under applicable law: (i) characterize any nonprincipal payment as an expense, fee or premium rather than as interest; (ii) exclude voluntary prepayments and the effects thereof; and (iii) amortize, prorate, allocate and spread the total amount of interest throughout the entire term of this Note (including any renewals or extensions) so that the interest rate is uniform throughout the entire term of this Note and does not exceed the maximum permitted by applicable law. The provisions of this paragraph shall control all existing and future agreements between the Undersigned and the holder hereof.

This Note is executed and delivered in the State of Texas and intended to be performed in Dallas County, Texas, and except to the extent that the laws of the United States of America may pre-empt or govern the terms hereof, this Note shall be governed by and construed in accordance with the laws of the State of Texas; and the Undersigned irrevocably agrees that in the event of any dispute involving this Note or any other instruments executed in connection herewith, venue for such dispute shall lie in any court of competent jurisdiction in Dallas County, Texas.

This Note and all the covenants, promises and agreements contained herein shall be binding upon and inure to the benefit of the respective heirs, devisees, legal and personal representatives, successors and assigns of the holder hereof and the Undersigned.
