Exhibit 10.1

CREDIT AGREEMENT

THIS CREDIT AGREEMENT (as amended, restated and supplemented from time to time, this “Agreement”) by and between THOMAS GROUP, INC., a Delaware corporation (“Borrower”) and JPMORGAN CHASE BANK, N.A., a national banking association (“Bank”), is dated as of December 5, 2006 (the “Effective Date”).

The parties hereto agree as follows:

ARTICLE I.

THE LOANS

SECTION 1.01.      Revolving Credit Note.  Subject to the terms and conditions hereof, Bank agrees to make loans (“Loan” or “Loans”) to Borrower from time to time before the Termination Date, not to exceed at any one time outstanding Five Million Five Hundred Thousand and No/100 Dollars ($5,500,000) (the “Commitment”).  Borrower has the right to borrow, repay and reborrow.  Each Loan must be at least $100,000 or the balance of the Commitment, whichever is less, and each repayment must be at least $100,000 or the principal balance of the Note (as defined below), whichever is less.  The Loans may only be used for working capital needs, capital expenditures and other general corporate purposes. Chapter 346 of the Texas Finance Code (which governs certain revolving loan accounts) will not apply to this Agreement, the Note or any Loan.  The Loans will be evidenced by, and will bear interest and be payable as provided in, the promissory note of Borrower dated of even date herewith (together with any and all renewals, extensions, modifications and replacements thereof and substitutions therefor, the “Note”).  “Termination Date” means the earlier of: (a) March 31, 2009; (b) the date specified by Bank pursuant to Section 6.1 hereof, or (c) the date specified by Bank pursuant to Section 5.12 hereof.

SECTION 1.02.      Reserved.

SECTION 1.03.      Required Payment.  If the unpaid amount of the Loans at any time exceeds the Commitment then in effect, Borrower must make a payment on the Note in an amount sufficient to reduce the unpaid principal balance of the Note to an amount no greater than the Commitment.  Such payment shall be accompanied by any prepayment charge required by the Note.

SECTION 1.04.      Commitment Fee.  Borrower agrees to pay to Bank a commitment fee in the amount of the product of the average daily unused amount of the Commitment times 0.25% per annum (“Commitment Fee”).  Accrued Commitment Fees payable under this Section shall be payable in arrears on the last day of each fiscal quarter and on the date on which the Commitment terminates, commencing on the first such date to occur after the date hereof.  All

Commitment Fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

SECTION 1.05.      Past-Due Amounts.  Each amount due to Bank in connection with the Loan Documents will bear interest from its due date until paid at the lesser of: (a) three percent (3%) per annum plus the then applicable rate under the Note, or (ii) the Highest Lawful Rate.

SECTION 1.06.      Capital Adequacy.  If Bank determines after the date of this Agreement that any change in applicable laws, rules or regulations regarding capital adequacy, or any change in the interpretation or administration thereof by any appropriate governmental agency, or compliance with any request or directive to Bank regarding capital adequacy (whether or not having the force of law) of any such agency, increases the capital required to be maintained with respect to the Loan or Note and therefore reduces the rate of return on Bank’s capital below the level Bank could have achieved but for such change or compliance (taking into consideration Bank’s policies with respect to capital adequacy), then Borrower will pay to Bank from time to time, within fifteen (15) days of Bank’s request, any additional amount required to compensate Bank for such reduction.  Bank will request any additional amount by delivering to Borrower a certificate of Bank setting forth the amount necessary to compensate Bank.  The certificate will be conclusive and binding, absent manifest error.  Bank may make any assumptions, and may use any allocations of costs and expenses and any averaging and attribution methods, which Bank in good faith finds reasonable.

ARTICLE II.

SECTION 7.05.      Documentary Matters.  This Agreement may be executed in several identical counterparts, on separate counterparts; each counterpart will constitute an original instrument, and all separate counterparts will constitute but one and the same instrument.  The headings and captions in the Loan Documents have been included solely for convenience and should not be considered in construing the Loan Documents.  If any provision of any Loan Document is invalid, illegal or unenforceable in any respect under any applicable law, the remaining provisions will remain effective.

SECTION 7.06.      Expenses.  Any provision to the contrary notwithstanding, and whether or not the transactions contemplated by this Agreement are consummated, Borrower agrees to pay on demand all out-of-pocket expenses (including, without limitation, the reasonable fees and expenses of counsel for Bank) in connection with the negotiation, preparation, execution, filing, recording, modification, supplementing and waiver of the Loan Documents and the making, servicing and collection of the Loans.  Borrower agrees to pay Bank’s standard Documentation Preparation and Processing Fee for preparation, negotiation and handling of this Agreement.  The obligations of Borrower under this and the following section will survive the termination of this Agreement.

claim, deficiency and expense (including interest, penalties, attorneys’ fees and amounts paid in settlement) to which Bank may become subject arising out of or based upon the Loan Documents, or any Loan, INCLUDING ALL LOSS, LIABILITY, OBLIGATION, DAMAGE, PENALTY, JUDGMENT, CLAIM, DEFICIENCY AND EXPENSE RESULTING FROM BANK’S OWN NEGLIGENCE, except and to the extent caused by Bank’s gross negligence or willful misconduct.

SECTION 7.09.      Usury Not Intended.  No provision of this Agreement or of any other Loan Document shall require the payment or the collection of interest in excess of the maximum amount permitted by applicable law.  If any excess of interest in such respect is hereby provided for, or shall be adjudicated to be so provided, in any Loan Document or otherwise in connection with this loan transaction, the provisions of this Section shall govern and prevail and neither the Borrower nor the sureties, guarantors, successors, or assigns of the Borrower shall be obligated to pay the excess amount of such interest or any other excess sum paid for the use, forbearance, or detention of sums loaned pursuant hereto.  In the event Bank ever receives, collects, or applies as interest any such sum, such amount which would be in excess of the maximum amount permitted by applicable law shall be applied as a payment and reduction of the principal of the indebtedness evidenced by the Note; and, if the principal of the Note has been paid in full, any remaining excess shall forthwith be paid to the Borrower.  In determining whether or not the interest paid or payable exceeds the Highest Lawful Rate, the Borrower and Bank shall, to the extent permitted by applicable law, (a) characterize any non-principal payment as an expense, fee, or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the entire contemplated term of the indebtedness evidenced by the Note so that interest for the entire term does not exceed the Highest Lawful Rate.

SECTION 7.11.      Jury Trial Waiver.  TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW, BORROWER AND BANK HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVE ANY RIGHT TO TRIAL BY JURY THAT BORROWER OR BANK MAY HAVE IN ANY ACTION OR PROCEEDING, IN LAW OR IN EQUITY, IN CONNECTION WITH THIS AGREEMENT OR THE OBLIGATIONS. BORROWER REPRESENTS AND WARRANTS THAT NO REPRESENTATIVE OR AGENT OF BANK HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT BANK WILL NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THIS RIGHT TO JURY TRIAL WAIVER. BORROWER ACKNOWLEDGES THAT BANK HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE PROVISIONS OF THIS SECTION.

SECTION 7.12.      NO ORAL AGREEMENTS.  THIS AGREEMENT, THE NOTE AND THE OTHER LOAN DOCUMENTS REFERRED TO HEREIN REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES HERETO.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES HERETO.
