ENTERPRISE FINANCIAL SERVICES CORP.
EXECUTIVE EMPLOYMENT AGREEMENT

          THIS AGREEMENT, is made by and between PETER F. BENOIST (the “Executive”) and ENTERPRISE FINANCIAL SERVICES CORP, a Delaware corporation (the “Company”), on this 5^th day of January, 2006, but shall be effective as of November 1, 2005 (the “Effective Date”).

          WITNESSETH:

          WHEREAS, Executive desires to be employed by the Company, and the Company desires to employ Executive, on the terms, covenants and conditions hereinafter set forth in this Agreement.

          NOW, THEREFORE, for the reasons set forth above, and in consideration of the mutual promises and agreements herein set forth, the Company and Executive agree as follows:

          1.           Employment.  Subject to the terms and conditions set forth in this Agreement, the Company hereby employs Executive for the Contract Term as hereafter defined.  During the Contract Term, Executive shall serve as Chairman of the Board and Executive Vice President of the Company, and the Chairman and Chief Executive Officer of the Company’s subsidiary, Enterprise Bank, and shall have such duties and responsibilities as are customarily assigned to individuals serving in such positions and such other duties as the Board of Directors (the “Board”) may from time to time specify consistent with such corporate offices and positions.  Executive shall comply with all polices and procedures of the Company generally applicable to executive employees of the Company and to the extent consistent with the provisions of this Agreement.  The duties and responsibilities Executive is to perform hereunder shall be conducted primarily from the St. Louis, Missouri metropolitan area where the principal offices of the Company are located.  Executive may be required from time to time to perform his duties hereunder on an occasional basis at such other places as the Board shall designate or as the interests or business opportunities of the Company may require; provided, however, that without Executive’s consent, the Executive shall not be required to relocate his residence from the St. Louis, Missouri metropolitan area.  Executive hereby accepts such employment and agrees to serve the Company in such capacities for the term of this Agreement.

          2.          Term of Employment.  Except as otherwise provided herein, the term of this Agreement shall be for term commencing on the Effective Date and ending on December 31, 2008 (the “Contract Term”).  The Contract Term may be extended by mutual written agreement of Executive and the Company upon such terms, provisions and conditions which are mutually acceptable to Executive and the Company.  Notwithstanding any expiration of this Agreement at the end of the Contract Term, to the extent that Executive remains an employee of the Company thereafter, unless the parties otherwise agree in writing, (i) the obligations of the Company under sections 4, 6 and 11 of this Agreement shall remain applicable and (ii) the obligations of Executive under sections 7, 8 and 9 of this Agreement shall remain applicable.  The term during which Executive is an employee of the Company, including any period of employment following the Contract Term, is referred to as the “Employment Term.”

          3.          Devotion to Duties.  Executive agrees that during the Employment Term he will devote all of his skill, knowledge, commercial efforts and working time to the conscientious and faithful performance of his duties and responsibilities to the Company (except for (i) permitted vacation time and absence for sickness or similar disability and (ii) to the extent that it does not interfere with the performance of Executive’s duties hereunder:  (A) such reasonable time as may be devoted to the fulfillment of Executive’s civic and charitable activities and (B) such reasonable time as may be necessary from time to time for personal financial matters).  Executive will use his best good faith efforts to promote the success of the Company’s business and will cooperate fully with the Board in the advancement of the best interests of the Company.  Executive will agree to serve as a director of the Company, or as a director or officer of any of its Subsidiaries or Affiliates, without additional compensation.

          4.          Compensation of Executive.

             4.1          Base Salary.  During the Employment Term, the Company shall pay to the Executive as compensation for the services to be performed by the Executive a base salary of $350,000 per year (the “Base Salary”).  The Base Salary shall be payable in installments in accordance with the Company’s normal payroll practice and shall be subject to such withholdings and other ordinary employee withholdings as may be required by law.  The Base Salary may be adjusted from time to time in the sole discretion of the Board, but shall not be reduced without the consent of Executive.

             4.2          Targeted Bonus.  In addition to the compensation set forth elsewhere in this Section 4, for each year or portion thereof during the Employment Term and any extensions thereof, the Executive shall qualify for a targeted annualized bonus (“Targeted Bonus”) based upon meeting established targeted goals.  No later than the Company’s January Board meeting in 2006 and subsequent years, the Company and Executive shall agree upon certain targeted financial and operating goals (“Targets”) for that calendar year with performance levels set at Threshold and Target.  The established Targets shall be consistent with the financial plan for the Company as adopted by the Company’s Board.  Within 75 days after the end of each calendar year, the Board (or a committee of the Board to which the Board has delegated such authority) shall make a good faith determination as to the extent to which the Targets have been met by the Company for the preceding calendar year.  Based upon meeting previously established goals for 2005, Executive shall be entitled to a Targeted Bonus of $174,000 for performance at Threshold and $241,667 for performance at Target.  For 2006, 2007 and 2008, Executive shall be entitled to a Targeted Bonus of 41.1428% of the then applicable Base Salary for the year for performance at Threshold and 57.1429% of the then applicable Base Salary for the year for performance at Target.  In each of the four years, for performance between Threshold and Target and above Target the payment shall be interpolated on a straight line basis between Threshold and Target and above; provided that (i) for 2005 that portion of the Targeted Bonus attributable to earnings per share shall be increased by 40% to the extent that performance is above Target, and (ii) for 2006, 2007 and 2008, the

2

entire portion of the Targeted Bonus attributable to performance above Target shall be increased no less than 23% and no more than 43% as determined by the Board (or a committee of the Board to which the Board has delegated such authority).  No Targeted Bonus shall be due for performance below Threshold.  Executive shall also be eligible to receive such other bonuses or incentive payments as may be approved by the Board of Directors.

             4.3          Benefits.  Executive shall be entitled to participate, during the Employment Term, in all regular employee benefit and deferred compensation plans established by each of Enterprise Bank (to the extent such participation is not restricted by the Internal Revenue Code of 1986 (the “Code”)) and the Company, including, without limitation, any savings and profit sharing plan, incentive stock plan, dental and medical plans, life insurance and disability insurance, such participation to be as provided in said employee benefit plans in accordance with the terms and conditions thereof as in effect from time to time and subject to any applicable waiting period.  Executive shall also be entitled to four weeks of paid vacation during each year of the Employment Term, provided that any vacation not used in any year shall be forfeited and not carried over to any subsequent year.

             4.4          Office and Secretary.  Executive will have a private office, secretarial assistance, administrative support, and such other facilities and services as the Company deems necessary or appropriate for the performance of the Executive’s duties under this Agreement.

             4.5          Reimbursement of Expenses.  The Company will provide for the payment or reimbursement of all reasonable and necessary expenses incurred by the Executive in connection with the performance of his duties under this Agreement in accordance with the Company’s expense reimbursement policy, as such may change from time to time.  Without limiting the foregoing, the Company further agrees during the Employment Term (i) to reimburse Executive for monthly automobile expense by means of a $500 per month automobile allowance; and (ii) to reimburse Executive for dues and assessments in respect of club memberships maintained by Executive up to a maximum of $7,500 per year.

             4.6          Stock Options and Long-Term Incentives.  At such time as awards are made under the Company’s 2005 Long Term Incentive Compensation Plan and any subsequently adopted long-term incentive compensation plan, Executive shall be entitled to receive:  (i) a grant in 2005 of $252,000 in restricted stock units based on the Company’s performance for 2004 and 2005 with the award due in 2006; (ii) a grant in 2005 of $280,000 in restricted stock units based on the Company’s performance for 2004, 2005 and 2006 with the award due in 2007; (iii) a grant in 2006 of $308,000 in restricted stock units based on the Company’s performance for 2005, 2006 and 2007 with the award due in 2008; (iv) a grant in 2006 of $308,000 in restricted stock units based on the Company’s performance for 2006, 2007 and 2008 with the award due in 2009; and (v) a grant in 2007 of $308,000 in restricted stock units based on the Company’s performance for 2007, 2008 and 2009 with the award due in 2010.  All such grants of restricted stock units shall be subject to meeting applicable performance standards. In addition, effective

3

with the execution of this Agreement, Executive shall be granted options to purchase that number of shares of the Company’s Common Stock determined by dividing 25% of Base Salary by the price of the Company’s Common Stock on the date of the grant pursuant to the terms of the Company’s 2002 Stock Incentive Plan.  On the anniversary date of this Agreement in each of 2006 and 2007, Executive shall also be granted options to purchase that number of shares of the Company’s Common Stock determined by dividing 25% of the then applicable Base Salary by the price of the Company’s Common Stock on the date of the grant, which options shall be granted under and be subject to one or more of the Company’s existing or subsequently adopted plans.  All such options shall vest and become exercisable at the rate of 33-1/3% on the first, second and third anniversary dates of the grant, provided that Executive remains continuously employed by the Company through such dates.  Executive shall also be eligible for additional grants of restricted stock units and options annually as determined by the Board, under the terms of the Company’s 2002 Stock Incentive Plan as adopted and/or amended by the Company from time to time.  All grants of options and restricted stock units shall be subject to there being a sufficient number of shares available for such grants under plans approved by the Company’s stockholders.

             4.7          Annual Review.  The Compensation Committee of the Board shall, no less than annually, review the amount of Base Salary, Targeted Bonus, restricted stock units, and stock options awarded to Executive.

          5.          Termination of Employment.

             5.1          Termination for Cause.  “Termination for Cause”, as hereinafter defined, may be effected by the Company at any time during the term of this Agreement by written notification to Executive, specifying in detail the basis for the Termination for Cause.  Upon Termination for Cause, Executive shall immediately be paid all accrued salary, bonus compensation to the extent earned, vested deferred compensation, if any, (other than pension plan or profit sharing plan benefits which will be paid in accordance with the terms of the applicable plan), any benefits under any plans of the Company in which the Executive is a participant to the full extent of the Executive’s rights under such plans, accrued vacation pay for the year in which termination occurs, and any appropriate business expenses incurred by Executive reimbursable by the Company in connection with his duties hereunder, all to the date of termination, but Executive shall not be paid any other compensation or reimbursement of any kind, including without limitation, severance compensation.  “Termination for Cause” shall mean termination by the Company of Executive’s employment by the Company by reason of (a) an order of any federal or state regulatory authority having jurisdiction over the Company, (b) the willful failure of Executive substantially to perform his duties hereunder (other than any such failure due to Executive’s physical or mental illness); (c) a willful breach by Executive of any material provision of this Agreement or of any other written agreement with the Company or any of its Affiliates; (d) Executive’s commission of a crime that constitutes a felony or other crime of moral turpitude or criminal fraud; or (e) chemical or alcohol dependency which materially and adversely affects Executive’s performance of his duties under this Agreement; (f) any act of disloyalty or breach of responsibilities to the Company by the Executive which is intended by the Executive to cause material harm to

4

the Company; (e) misappropriation (or attempted misappropriation) of any of the Company’s funds or property.  If subsequent to Executive’s termination of employment hereunder for other than Cause it is determined in good faith by the Company that Executive’s employment could have been terminated for Cause hereunder, Executive’s employment shall be deemed to have been terminated for Cause retroactively to the date the events giving rise to Cause occurred.

            5.2          Termination Other Than for Cause.  Notwithstanding any other provisions of this Agreement, the Company may effect a “Termination Other Than For Cause”, as hereinafter defined, at any time upon giving written notice to Executive of such termination.  Upon any Termination Other Than for Cause, subject to the effectiveness of Executive’s execution of a release and waiver of all claims with respect to Executive’s employment against the Company its Affiliates and their respective officers and directors in a form reasonably satisfactory to the Company other than rights under this Section 5.2 and subject to Executive’s compliance with the terms and conditions contained in this Agreement, Executive shall within 30 days after such termination be paid all accrued salary, bonus compensation to the extent earned, vested deferred compensation (other than pension plan or profit sharing plan benefits which will be paid in accordance with the applicable plan), accrued vacation pay for the year in which termination occurs, any benefits under any plans of the Company in which Executive is a participant to the full extent of Executive’s rights under such plans, and any appropriate business expenses incurred by Executive in connection with his duties hereunder, all to the date of termination, and all severance compensation provided in subsection 6.2.  In addition, subject to the conditions set forth above, upon such termination of employment, all stock options granted to Executive shall become fully vested and exercisable and all restricted common stock granted to Executive shall fully vest and become transferable.  “Termination Other Than for Cause” shall mean any termination by the Company of Executive’s employment with the Company other than a termination pursuant to subsection 5.1, 5.3, 5.4, 5.5 or 5.6, or termination by Executive of Executive’s employment with the Company by reason of (i) the Company’s material breach of this Agreement, (ii) the assignment of Executive without his consent to a position, responsibilities or duties of a materially lesser status or degree of responsibility than his position, responsibilities or duties as of the Effective Date, (iii) the requirement by the Company that Executive be based anywhere other than the St. Louis, Missouri metropolitan area, without Executive’s consent or (iv) the failure of Executive to be reelected to the Board by its stockholders or the failure of the Board to re-nominate him for reelection without Executive’s consent.

            5.3          Termination by Reason of Disability.  If, during the term of this Agreement, the Executive, in the reasonable judgment of the Board of Directors, (i) has failed to perform his duties under this Agreement on account of illness or physical or mental incapacity, and (ii) such illness or incapacity continues for a period of more than 90 consecutive days, or 90 days during any 180 day period, the Company shall have the right to terminate Executive’s employment hereunder by written notification to Executive and payment to Executive of all accrued salary, bonus compensation to the extent earned, vested deferred compensation, if any, (other than pension plan or profit sharing plan benefits which will be paid in accordance with the applicable plans), accrued vacation

5

            5.5          Voluntary Termination.  In the event of a “Voluntary Termination,” as hereinafter defined, provided that the Executive provides the Company with at least 90 days notice of such termination (which notice and any requirement for service may be waived or shortened by the Company), the Company shall within 30 days after such termination pay all accrued salary, bonus compensation to the extent earned, vested deferred compensation, if any, (other than pension plan or profit sharing plan benefits which will be paid in accordance with the applicable plans), any benefits under any plans of the Company in which Executive is a participant to the full extent of Executive’s rights under such plans, accrued vacation pay for the year in which termination occurs, and any appropriate business expenses incurred by Executive in connection with his duties hereunder, all to the date of termination, but no other compensation or reimbursement of any kind, including without limitation, severance compensation.  “Voluntary Termination” shall mean termination by Executive of Executive’s employment other than (i) constructive termination as described in paragraphs (i) through (iv) of subsection 5.2, (ii) termination by reason of Executive’s disability as described in subsection 5.3, (iii) termination by reason of Executive’s death as described in subsection 5.4, and (iv) Termination Upon a Change in Control as described in subsection 5.6.

As used in this Section 5.6, the definitions of the terms “beneficial owner” and “group” shall have the meanings ascribed to those terms in Rule 13(d)(3) under the Securities Exchange Act of 1934.  As used in this Section 5.6, the term “Continuing Directors” shall mean, as of any date of determination, (i) any member of the Board of Directors on the Effective Date of this Agreement, (ii) any person who has been a member of the Board of Directors for the two years immediately preceding such date of determination, or (iii) any person who was nominated for election or elected to the Board of Directors with the affirmative vote of the greater of (A) a majority of the Continuing Directors who were members of the Board of Directors at the time of such nomination or election or (B) at least four Continuing Directors but excluding, for purposes of this clause (iii), any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies by or on behalf of a Person other than the Board of Directors of the Company.  “Control” means the direct or indirect ownership of voting securities constituting more than fifty percent (50%) of the issued voting securities of a corporation.

8

	(b)          In the event that Executive is not otherwise entitled to fully exercise all awards granted to him under any stock option plan maintained by the Company and any such plan does not otherwise provide for acceleration of exerciseability upon the occurrence of the Change in Control described herein, such awards shall become immediately exercisable upon a Change in Control.
	(c)          All restricted stock granted to Executive will vest and become transferable.
	(d)          Executive shall continue to accrue retirement benefits and shall continue to enjoy any benefits under any plans of the Company in which Executive is a participant to the full extent of Executive’s rights under such plans, including any perquisites provided under this Agreement, through the remainder of the Employment Term; provided, however, that the benefits under any such plans of the Company in which Executive is a participant, including any such perquisites, shall cease upon Executive’s obtaining other employment.  If necessary to provide such benefits to Executive, the Company shall, at its election, either: (i) amend its employee benefit plans to provide the benefits described in this paragraph (c), to the extent that such is permissible under the nondiscrimination requirements and other provisions of the Internal Revenue Code of 1986 (the “Code”) and the provisions of Executive Retirement Income Security Act of 1974, or (ii) provide separate benefit arrangements or cash payments so that Executive receives amounts equivalent thereto, net of tax consequences.
6.2          Termination Other Than for Cause.  In the event Executive’s employment is terminated in a Termination Other Than for Cause, Executive shall be paid as severance compensation his Base Salary, at the rate payable at the time of such termination, through the remaining period of the Contract Term or the one year period commencing on the effective date of such termination (whichever period is shorter) plus (i) any accrued and unpaid Bonus due Executive under paragraph 4.3 of this Agreement and (ii) an amount equal to the Targeted Bonuses due (based on the Base Salary then in effect) for the year in which such termination of employment as though all requisite targets were fully and completely achieved.  Notwithstanding any provision in this subsection 6.2 to the contrary, the Company may, in the Company’s sole discretion, by delivery of a notice to Executive within 30 days following a Termination Other Than for Cause, elect to remit to Executive a lump sum severance payment by bank cashier’s check equal to the present value of the flow of cash payments that would otherwise be paid to Executive pursuant to this subsection 6.2.  Such present value shall be determined as of the date of delivery of the notice of election by the Company and shall be based on a discount rate equal to the prime rate, as reported in The Wall Street Journal, on the date of delivery of the election notice.  If the Company elects to remit a lump sum severance payment, the Company shall make such payment to Executive within 30 days following the date on which the Company notifies Executive of its election.  In the event that

9

Executive is not otherwise entitled to fully exercise all awards granted to him under the Company’s Incentive Stock Plan, and the Incentive Stock Plan does not otherwise provide for acceleration of exerciseability upon the occurrence of a Termination Other Than for Cause described herein, such awards shall become immediately exercisable upon a Termination Other Than for Cause.

            6.3          Termination Upon Any Other Event.  In the event of a Voluntary Termination, Termination For Cause, termination by reason of Executive’s disability pursuant to subsection 5.5 or termination by reason of Executive’s death pursuant to subsection 5.6, Executive or his estate shall not be paid any severance compensation.

          7.          Confidentiality.  Executive agrees to hold in strict confidence all non-public information concerning any matters affecting or relating to the business of the Company, including without limiting the generality of the foregoing non-public information concerning its manner of operation, business or other plans, data bases, marketing programs, protocols, processes, computer programs, client lists, marketing information and analyses, operating policies or manuals or other data.  Executive agrees that he will not, directly or indirectly, use any such information for the benefit of others than the Company or disclose or communicate any of such information in any manner whatsoever other than to the directors, officers, employees, agents and representatives of the Company who need to know such information, who shall be informed by Executive of the confidential nature of such information and directed by Executive to treat such information confidentially.  Upon the Company’s request, Executive shall return all information furnished to him related to the business of the Company without retaining any copies in electronic or other form.  The above limitations on use and disclosure shall not apply to information which Executive can demonstrate:  (a) was known to Executive before receipt thereof from the Company; (b) is learned by Executive from a third party entitled to disclose it; or (c) becomes known publicly other than through Executive; (c) is disclosed by Executive upon authority of the Board or any committee of the Board; (d) is disclosed pursuant to any legal requirement or (e) is disclosed pursuant to any agreement to which the Company or any of its Subsidiaries or Affiliates is a party.  The parties hereto stipulate that all such information is material and confidential and gravely affects the effective and successful conduct of the business of the Company and the Company’s goodwill, and that any breach of the terms of this Section 7 shall be a material breach of this Agreement.  The terms of this Section 7 shall survive and remain in effect following any termination of this Agreement.

          8.          Use of Proprietary Information.  Executive recognizes that the Company possesses a proprietary interest in all of the information described in Section 7 and has the exclusive right and privilege to use, protect by copyright, patent or trademark, manufacture or otherwise exploit the processes, ideas and concepts described therein to the exclusion of Executive, except as otherwise agreed between the Company and Executive in writing.  Executive expressly agrees that any products, inventions, discoveries or improvements made by Executive, his agents or affiliates, during the term of this Agreement, based on or arising out of the information described in Section 7 shall be the property of and inure to the exclusive benefit of the Company.  Executive further agrees that any and all products, inventions, discoveries or improvements developed by Executive (whether or not able to be protected by copyright, patent or trademark) in the scope of his employment, or involving the use of the Company’s time, materials or other resources, shall be promptly disclosed to the Company and shall become the exclusive property of the Company.

10

          9.          Non-Competition Agreement.

              9.1          Non-Competition.  Executive agrees that, during the Employment Term and for a period of one year following any termination of such employment, Executive shall not, without the prior written consent of the Company, directly or indirectly, own, manage, operate, control, be connected with as an officer, employee, partner, consultant or otherwise, or otherwise engage or participate in (except as an employee of the Company, or Affiliate of it) any corporation or other business entity engaged in the operation, ownership or management of a bank, trust company or financial services business within the Metropolitan Statistical Areas of St. Louis, Kansas City or any other city in which the Company or any of its Affiliates has an office at the time of such termination.  Notwithstanding the foregoing, the ownership by Executive of less than 1% of any class of the outstanding capital stock of any corporation conducting such a competitive business which is regularly traded on a national securities exchange or in the over-the-counter market shall not be a violation of the foregoing covenant.

              9.2          Non-Solicitation.  During the period of actual employment and, in addition, the period, if any, during which Executive shall be entitled to severance compensation pursuant to Section 6 (notwithstanding an election by Executive to receive a lump sum severance payment for such period), Executive shall not, except on behalf of or with the prior written consent of the Company, directly or indirectly, entice or induce, or attempt to entice or induce, any employee of the Company to leave such employ, or employ any such person in any business similar to or in competition with that of the Company.  Executive hereby acknowledges and agrees that the provisions set forth in this subsection 9.2 constitute a reasonable restriction on his ability to compete with the Company.

              9.3          Saving Provision.  The parties hereto agree that, in the event a court of competent jurisdiction shall determine that the geographical or durational elements of this covenant are unenforceable, such determination shall not render the entire covenant unenforceable. Rather, the excessive aspects of the covenant shall be reduced to the threshold which is enforceable, and the remaining aspects shall not be affected thereby.

              9.4          Equitable Relief.  Executive acknowledges that the extent of damages to the Company from a breach of Sections 7, 8 and 9 of this Agreement would not be readily quantifiable or ascertainable, that monetary damages would be inadequate to make the Company whole in case of such a breach, and that there is not and would not be an adequate remedy at law for such a breach.  Therefore, Executive specifically agrees that the Company is entitled to injunctive or other equitable relief (without any requirement to post any bond or other security) from a breach of Sections 7, 8 and 9 of this Agreement, and hereby waives and covenants not to assert against a prayer for such relief that there exists an adequate remedy at law, in monetary damages or otherwise.

11

          10.          Assignment.   This Agreement shall not be assignable by Executive and shall not be assignable by the Company except by operation of law or to a successor entity acquiring all or substantially all the Company’s business or assets.  No such assignment shall affect any determination of whether such assignment involves a Change of Control for purposes of this Agreement.  In the event of any assignment permitted hereby, the duties and responsibilities of Executive performed for the assignee shall not, without the written consent of Executive, be materially increased, altered or diminished in a manner inconsistent with Executive’s duties and responsibilities hereunder for the Company.

          11.          Indemnification.  The Company shall indemnify the Executive to the full extent provided for in the Bylaws of the Company, and no amendment of such Bylaws shall diminish the Company’s obligation to indemnify the Executive pursuant to this Agreement.

          12.          Entire Agreement.  This Agreement and any agreements entered into after the date hereof under any of the Company’s benefit plans or compensation programs as described in Section 4 contain the complete agreement concerning the employment arrangement between the parties, including without limitation severance or termination pay, and shall, as of the Effective Date, supersede all other agreements or arrangements between the parties with regard to the subject matter hereof.

          13.          Binding Agreement.  This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns.  The obligations of the Company under this Agreement shall not be terminated by reason of any liquidation, dissolution, bankruptcy, cessation of business or similar event relating to the Company.  This Agreement shall not be terminated by reason of any merger, consolidation or reorganization of the Company, but shall be binding upon and inure to the benefit of the surviving or resulting entity.

          14.          Modification.  No waiver or modification of this Agreement or of any covenant, condition, or limitation herein contained shall be valid unless authorized by the Board and reduced to in writing and duly executed by the party to be charged therewith and no evidence of any waiver or modification shall be offered or received in evidence of any proceeding, arbitration, or litigation between the parties hereto arising out of or affecting this Agreement, or the rights or obligations of the parties thereunder, unless such waiver or modification is in writing, duly executed as aforesaid.

          15.          Severability.  All agreements and covenants contained herein are severable, and in the event any of them shall be held to be invalid or unenforceable by any court of competent jurisdiction, this Agreement shall be interpreted as if such invalid agreements or covenants were not contained herein.

          16.          Manner of Giving Notice.  All notices, requests and demands to or upon the respective parties hereto shall be sent by hand, certified mail, overnight air courier service, in each case with all applicable charges paid or otherwise provided for, addressed as follows, or to such other address as may hereafter be designated in writing by the respective parties hereto:
