EMPLOYMENT AGREEMENT

EMPLOYMENT AGREEMENT

     EMPLOYMENT AGREEMENT dated as of March 26, 2007, by and between Cogdell Spencer Inc., a Maryland corporation (the “REIT”), Cogdell Spencer LP, a Delaware Limited Partnership (the “Operating Partnership”) each with its principal place of business at 4401 Barclay Downs Drive, Suite 300, Charlotte, North Carolina ###-###-####, and Heidi Barringer, residing at the address set forth on the signature page hereof (the “Executive”).

     WHEREAS, the REIT and the Operating Partnership (collectively, the “Company”) wish to employ the Executive, and the Executive wishes to accept such offer, on the terms set forth below:

     Accordingly, the parties hereto agree as follows:

     1. Term. The Company hereby employs the Executive, and the Executive hereby accepts such employment, for an initial term (the “Initial Term”) commencing on April 5, 2007 and continuing for a three-year period, unless sooner terminated in accordance with the provisions of Section 4 or Section 5; with such employment to continue for successive one-year periods in accordance with the terms of this Agreement (subject to termination as aforesaid) unless either party notifies the other party of non-renewal in writing prior to 90 days before the expiration of the initial term and each annual renewal, as applicable (the Initial Term, together with any such extensions of employment hereunder, shall hereinafter be referred to as the “Term”).

     2. Duties. During the Term, the Executive shall be employed by the Company as Executive Vice President and, as such, the Executive shall faithfully perform for the Company the duties of said office and shall perform such other duties of an executive, managerial or administrative nature as shall be specified and designated from time to time by the CEO, Board of Directors of the Company (the “Board”) or the General Partner of the Operating Partnership (the “General Partner”) (including, without limitation, the performance of duties for affiliates and subsidiaries of the Company). The Executive shall devote

substantially all of her business time and effort to the performance of her duties hereunder; provided that, the following activities do not interfere with the Executive’s ability to perform her duties hereunder, the Executive shall not be prohibited from performing personal and charitable activities and engaging in any other business interests as may be approved by the CEO, Board or the General Partner. Notwithstanding the foregoing, unless otherwise consented to by the parties hereto, in the event of any termination of employment with either the REIT or the Operating Partnership at a time when the REIT and the Operating Partnership are affiliates, then such termination will be considered to be a termination of such employment with the Company. Nothing herein shall restrict the ability of the Operating Partnership from classifying the Executive as a non-employee service provider thereto for tax-administrative purposes, for purposes of employee benefit plans and programs and for such other purposes as it may deem appropriate.

     3. Compensation.

          3.1 Salary. The Company shall pay the Executive during the Term a salary at the rate of $200,000 per annum (the “Annual Salary”), in accordance with the customary payroll practices of the Company applicable to senior executives (or, if there is no such policy, such practices of the Company’s principal affiliates). At least annually, the CEO, Board or the General Partner shall review the Executive’s Annual Salary and may provide for increases therein as it may in its discretion deem appropriate.

          3.2 Bonus. During the Term, in addition to the Annual Salary, for each fiscal year of the Company ending during the Term, the Executive shall have the opportunity to receive an annual bonus in an amount to be determined by the Company (the “Annual Bonus”).

          3.3 Benefits — In General. The Executive shall be permitted during the Term to participate in, and the Company shall, to the extent permitted under the following plans and programs, waive any waiting period with respect to, any group life, hospitalization or disability insurance plans, health programs, equity-based plans, retirement plans, fringe benefit programs and similar benefits that may be available to other senior executives of the Company generally, on the same terms as such other

executives, in each case to the extent that the Executive is eligible under the terms of such plans or programs.

          3.4 Expenses. The Company shall pay or reimburse the Executive for all ordinary and reasonable out-of-pocket expenses actually incurred (and, in the case of reimbursement, paid) by the Executive during the Term in the performance of the Executive’s services under this Agreement; provided that the Executive submits proof of such expenses, with the properly completed forms as prescribed from time to time by the Company.

          3.5. Certain Specific Benefits. The Company shall make available to the Executive, vacation of 20 business days per year, including the fiscal year ending December 31, 2007, and an appropriate Company car allowance consistent with car allowances for other senior executives.

     4. Termination upon Death or Disability. If the Executive dies during the Term, the Term shall terminate as of the date of death, and the obligations of the Company to or with respect to the Executive shall terminate in their entirety upon such date except as otherwise provided under this Section 4. If the Executive by virtue of ill health or other disability is unable to perform substantially and continuously the duties assigned to her for more than 180 consecutive or non-consecutive days out of any consecutive 12-month period, the Company shall have the right, to the extent permitted by law, to terminate the employment of the Executive upon notice in writing to the Executive. Upon termination of employment due to death or disability, (i) the Executive (or the Executive’s estate or beneficiaries in the case of the death of the Executive) shall be entitled to receive any Annual Salary, Annual Bonus (which Annual Bonus for the fiscal year ending December 31, 2007, for purposes of this Section 4(i), shall accrue monthly at a rate of $8,333) and other benefits earned and accrued under this Agreement prior to the date of termination (and reimbursement under this Agreement for expenses incurred prior to the date of termination), (ii) all outstanding unvested equity-based awards (including, without limitation, stock options and restricted stock) held by the Executive shall fully vest and become immediately exercisable, as applicable, subject to the other terms of such awards, and (iii) except as otherwise required under applicable law, the Executive (or, in the event of her death, her estate and beneficiaries) shall have no

further rights to any other compensation or benefits hereunder on or after the termination of employment, or any other rights hereunder.

     5. Certain Terminations of Employment.

          5.1 Termination by the Company for Cause; Termination by the Executive without Good Reason.

          (a) For purposes of this Agreement, “Cause” shall mean the Executive’s:

          (i) conviction of, or formal admission to, a felony;

          (ii) engagement in the performance of her duties hereunder, or otherwise to the material and demonstrable detriment of the Company, in willful misconduct, willful or gross neglect, fraud, misappropriation or embezzlement;

          (iii) repeated failure to adhere to the directions of the CEO, Board or the General Partner, or to adhere to the Company’s policies and practices;

          (iv) willful and continued failure to substantially perform her duties properly assigned to her (other than any such failure resulting from her disability) after demand for substantial performance is delivered by the Company specifically identifying the manner in which the Company believes the Executive has not substantially performed such duties;

          (v) breach of any of the provisions of Section 6; or

          (vi) breach in any material respect of the terms and provisions of this Agreement and failure to cure such breach within 90 days following written notice from the Company specifying such breach;

provided that the Company shall not be permitted to terminate the Executive for Cause except on written notice given to the Executive at any time following the occurrence of any of the events described in clauses (i), (ii) or (v) above and on written notice given to the Executive at any time not more than 30 days following the occurrence of, or if later, the Company’s knowledge of, any of the events described in clause (iii), (iv) or (vi) above. No termination for Cause shall be effective unless the Board or the General Partner makes a Cause determination after notice to the Executive and the Executive has been provided with the opportunity (with counsel of her choice) to contest the determination at a meeting of the Board or with the board of trustees the General Partner.

          (b) During the Term, the Company may terminate the Executive’s employment hereunder for Cause, as provided above, and the Executive may terminate her employment without Good Reason on at least 30 days’ and not more than 60 days’ written notice given to the Company. If (i) the Company terminates the Executive for Cause, or the Executive terminates her employment and the termination by the Executive is not for Good Reason in accordance with Section 5.2 or covered by Section 5.3, the Executive shall receive Annual Salary and other benefits (but, in all events, and without increasing the Executive’s rights under any other provision hereof, excluding any bonuses not yet paid) earned and accrued under this Agreement prior to the termination of employment (and reimbursement under this Agreement for expenses incurred prior to the termination of employment); and (ii) a termination occurs in accordance with this Section 5.1, except as otherwise required under applicable law, the Executive shall have no further rights to any other compensation or benefits hereunder on or after the termination of employment, or any other rights hereunder.

          5.2 Termination by the Company without Cause; Termination by the Executive for Good Reason.

          (a) For purposes of this Agreement, “Good Reason” shall mean, unless otherwise consented to by the Executive,

          (i) the material reduction of the Executive’s authority, duties and responsibilities, or the assignment to the Executive of duties materially inconsistent with the Executive’s position or positions with the Company;

          (ii) a reduction in Annual Salary of the Executive;

          (iii) the relocation of the Executive’s office to more than 50 miles from Charlotte, North Carolina; or

          (iv) the Company’s material and willful breach of this Agreement.

Notwithstanding the foregoing, (A) Good Reason shall not be deemed to exist unless notice of termination on account thereof (specifying a termination date no later than 30 days from the date of such notice) is given no later than 90 days after the time at which the event or condition purportedly giving rise to Good Reason first occurs or arises and (B) if there exists (without regard to this clause (B)) an event or

condition that constitutes Good Reason, the Company shall have 60 days from the date notice of such a termination is given to cure such event or condition and, if the Company does so, such event or condition shall not constitute Good Reason hereunder.

          (b) During the Term, the Company may terminate the Executive’s employment at any time for any reason or no reason and the Executive may terminate the Executive’s employment with the Company for Good Reason. If the Company terminates the Executive’s employment and the termination is not covered by Section 4, 5.1 or 5.3, or the Executive terminates her employment for Good Reason and the termination by the Executive is not covered by Section 5.3, (i) the Executive shall receive Annual Salary, Annual Bonus (which Annual Bonus for the fiscal year ending December 31, 2007, for purposes of this Section 5.2(b)(i), shall accrue monthly at a rate of $8,333) and other benefits earned and accrued under this Agreement prior to the termination of employment (and reimbursement under this Agreement for expenses incurred prior to the termination of employment); (ii) the Executive shall receive (A) a cash payment equal to 1.99 times the sum of (x) the Executive’s Annual Salary (as in effect on the effective date of such termination) payable no later than 30 days after such termination and (y) the greater of (1) the average of the two previous Annual Bonuses received by the Executive as provided for in Section 3.2, or (2) the maximum amount payable under Section 3.2 for the fiscal year in which the termination occurs (the “Termination Bonus”), or, in the event the Executive has not received any Annual Bonuses pursuant to Section 3.2 at the time of such termination, the Termination Bonus shall be equal to the Annual Bonus the Executive would have received under Section 3.2 if the Executive would have remained employed through the period required to be entitled to receive the Annual Bonus and satisfied all target performance objectives, payable no later than 30 days after such termination (or, if later, as soon as practicable, but in no event more than 30 days after, the amount of the Termination Bonus is known) and (B) for a period of three years after termination of employment such continuing health benefits (including any medical, vision or dental benefits), under the Company’s health plans and programs applicable to senior executives of the Company generally as the Executive would have received under this Agreement (and at such costs to the Executive) as would have applied in the absence of such termination

(but not taking into account any post-termination increases in Annual Salary that may otherwise have occurred without regard to such termination and that may have favorably affected such benefits); (iii) all outstanding unvested equity-based awards held by the Executive shall vest and become immediately exercisable and shall otherwise become free of restrictions and be exercisable in accordance with their terms and the Executive shall become vested in any pension or other deferred compensation other than pension or deferred compensation under a plan intended to be qualified under Section 401(a) or 403(a) of the Internal Revenue Code of 1986, as amended; and (iv) except as otherwise required under applicable law, the Executive shall have no further rights to any other compensation or benefits hereunder on or after the termination of employment, or any other rights hereunder. To the extent that the Executive remains employed with the Company subsequent to December 31, 2007, for purposes of Section 5.2(b)(ii)(y) hereof, the Annual Bonus for the fiscal year ending December 31, 2007 shall be $100,000.

          (c) Notwithstanding clause (ii)(B) of the second sentence of Section 5.2(b), (i) nothing herein shall restrict the ability of the Company to amend or terminate the plans and programs referred to in such clause (ii)(B) from time to time in its sole discretion, but the Company may not reduce benefits already earned and accrued by, but not yet paid to, the Executive and (ii) the Company shall in no event be required to provide any benefits otherwise required by such clause (ii)(B) after such time as the Executive becomes entitled to receive benefits of the same type from another employer or recipient of the Executive’s services (such entitlement being determined without regard to any individual waivers or other similar arrangements).

          5.3 Change of Control.

          (a) Without duplication of the foregoing, upon a “Change in Control” (as defined below) while the Executive is employed, all outstanding unvested equity-based awards (including stock options and restricted stock) shall fully vest and become immediately exercisable, as applicable. In addition, if, after a Change in Control, the Executive terminates her employment with the Company for any reason on or before the first anniversary of the Change in Control, such termination shall be deemed a termination

by the Executive for Good Reason covered by Section 5.2, provided, that the Executive provides no less than 30 days’ advance written notice to the Company.

          (b) For purposes of this Agreement, “Change in Control” shall have the same meaning as in the Company 2005 Long Term Incentive Compensation Plan (or any successor plan thereof).

     6. Covenants of the Executive.

          6.1 Consideration. The Executive acknowledges, understands and agrees that, in consideration for agreeing to and complying with the terms and conditions contained in this Section 6 hereof, she will be entitled to a lump sum payment, payable no later than 30 days after a termination of the Executive’s employment under Section 5 of this Agreement, equal to the sum of (i) the Executive’s Annual Salary for one year and (ii) the greater of (A) the average of the two previous Annual Bonuses received by the Executive as provided for in Section 3.2, or (B) the maximum amount payable under Section 3.2 for the fiscal year in which the termination occurs, or, in the event the Executive has not received any Annual Bonuses pursuant to Section 3.2 at the time of such termination, such Annual Bonus shall be equal to the Annual Bonus the Executive would have received under Section 3.2 if the Executive would have remained employed through the period required to be entitled to receive the Annual Bonus and satisfied all target performance objectives. Notwithstanding the foregoing, within seven days of a termination of the Executive’s employment under Section 5 of this Agreement, the Company may give written notice to the Executive stating that it does not wish to enforce the terms and conditions contained in this Section 6, and upon issuance of such notice, the Company will not be obligated to pay and the Executive will not be entitled to receive any consideration under this Section 6 and the covenants contained in this Section 6 will have no force and effect. To the extent that the Executive remains employed with the Company subsequent to December 31, 2007, for purposes of Section 6.1(ii) hereof, the Annual Bonus for the fiscal year ending December 31, 2007 shall be $100,000.

          6.2 Covenant Against Competition; Other Covenants. The Executive acknowledges that (i) the principal business of the Company (which expressly includes for purposes of this Section 6 (and any related enforcement provisions hereof), its successors and assigns) is the ownership, operation, development, redevelopment, acquisition and management of strategically located medical office buildings and other healthcare related facilities (such business and any and all other businesses that after the date hereof, and from time to time during the Term, become material with respect to the Company’s then-overall business, herein being collectively referred to as the “Business”); (ii) the Company is one of the limited number of persons who have developed such a business; (iii) the Company’s Business is, in part, national in scope; (iv) the Executive’s work for the Company has given and will continue to give her access to the confidential affairs and proprietary information of the Company; (v) the covenants and agreements of the Executive contained in this Section 6 are essential to the business and goodwill of the Company; and (vi) the Company would not have entered into this Agreement but for the covenants and agreements set forth in this Section 6. Accordingly, the Executive covenants and agrees that:

          (a) By and in consideration of the payments to be provided by the Company hereunder, and further in consideration of the Executive’s exposure to the proprietary information of the Company, the Executive covenants and agrees that, during the period commencing on the date hereof and ending one year following the date upon which the Executive shall cease to be an employee of the Company and its affiliates (the “Restricted Period”), she shall not directly or indirectly, whether as an owner, partner, shareholder, principal, agent, employee, consultant or in any other relationship or capacity, (i) engage in any element of the Business (other than for the Company or its affiliates) or otherwise compete with the Company or its affiliates, (ii) render any services to any person, corporation, partnership or other entity (other than the Company or its affiliates) engaged in competition with the Company or its affiliates, or (iii) provide financial assistance to or otherwise obtain an ownership interest in a competitor of the Company or its affiliates; provided, however, that, notwithstanding the foregoing, the Executive may invest in securities of any entity, solely for investment purposes and without participating in the business thereof, if (A) such securities are traded on any national securities exchange

or the National Association of Securities Dealers, Inc. Automated Quotation System, (B) the Executive is not a controlling person of, or a member of a group which controls, such entity and (C) the Executive does not, directly or indirectly, own 5% or more of any class of securities of such entity.

          (b) During and after the Restricted Period, the Executive shall keep secret and retain in strictest confidence, and shall not use for her benefit or the benefit of others, except in connection with the business and affairs of the Company and its affiliates, all confidential matters relating to the Company’s Business and the business of any of its affiliates and to the Company and any of its affiliates, learned by the Executive heretofore or hereafter directly or indirectly from the Company or any of its affiliates (the “Confidential Company Information”), and shall not disclose such Confidential Company Information to anyone outside of the Company except with the Company’s express written consent and except for Confidential Company Information which is at the time of receipt or thereafter becomes publicly known through no wrongful act of the Executive or is received from a third party not under an obligation to keep such information confidential and without breach of this Agreement.

          (c) During the Restricted Period, the Executive shall not, without the Company’s prior written consent, directly or indirectly, knowingly (i) solicit or encourage to leave the employment or other service of the Company, or any of its affiliates, any employee or independent contractor thereof or (ii) hire (on behalf of the Executive or any other person or entity) any employee or independent contractor who has left the employment or other service of the Company or any of its affiliates within the one-year period which follows the termination of such employee’s or independent contractor’s employment or other service with the Company and its affiliates. From the date hereof through the end of the two-year period commencing with the Executive’s termination of employment with the Company, the Executive will not, whether for her own account or for the account of any other person, firm, corporation or other business organization, intentionally interfere with the Company’s or any of its affiliates’ relationship with, or endeavor to entice away from the Company or any of its affiliates, any person who during the 12-month period prior to the Executive’s termination is or was a customer or client of the Company or any of

its affiliates. While the Executive’s non-compete obligations under Section 6.2(a) are in effect, the Executive shall not publish any statement or make any statement under circumstances reasonably likely to become public that is critical of the Company or any of its affiliates, or in any way adversely affecting or otherwise maligning the Business or reputation of the Company or any of its affiliates.

          (d) All memoranda, notes, lists, records, property and any other tangible product and documents (and all copies thereof), whether visually perceptible, machine-readable or otherwise, made, produced or compiled by the Executive or made available to the Executive concerning the business of the Company or its affiliates, (i) shall at all times be the property of the Company (and, as applicable, any affiliates) and shall be delivered to the Company at any time upon its request, and (ii) upon the Executive’s termination of employment, shall be immediately returned to the Company.

          6.3 Rights and Remedies upon Breach.

          (a) The Executive acknowledges and agrees that any breach by her of any of the provisions of Section 6.2 (the “Restrictive Covenants”) would result in irreparable injury and damage for which money damages would not provide an adequate remedy. Therefore, if the Executive breaches, or threatens to commit a breach of, any of the provisions of Section 6.2, the Company and its affiliates, in addition to, and not in lieu of, any other rights and remedies available to the Company and its affiliates under law or in equity (including, without limitation, the recovery of damages); shall have the right and remedy to have the Restrictive Covenants specifically enforced (without posting bond and without the need to prove damages) by any court having equity jurisdiction, including, without limitation, the right to an entry against the Executive of restraining orders and injunctions (preliminary, mandatory, temporary and permanent) against violations, threatened or actual, and whether or not then continuing, of such covenants.

          (b) The Executive agrees that in any action seeking specific performance or other equitable relief, she will not assert or contend that any of the provisions of this Section 6 are unreasonable or otherwise unenforceable. The existence of any claim or cause of action by the Executive, whether

predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement of the Restrictive Covenants.

     7. Other Provisions.

          7.1 Severability. The Executive acknowledges and agrees that (i) she has had an opportunity to seek advice of counsel in connection with this Agreement and (ii) the Restrictive Covenants are reasonable in geographical and temporal scope and in all other respects. If it is determined that any of the provisions of this Agreement, including, without limitation, any of the Restrictive Covenants, or any part thereof, is invalid or unenforceable, the remainder of the provisions of this Agreement shall not thereby be affected and shall be given full effect, without regard to the invalid portions.

          7.2 Duration and Scope of Covenants. If any court or other decision-maker of competent jurisdiction determines that any of the Executive’s covenants contained in this Agreement, including, without limitation, any of the Restrictive Covenants, or any part thereof, is unenforceable because of the duration or geographical scope of such provision, then, after such determination has become final and unappealable, the duration or scope of such provision, as the case may be, shall be reduced so that such provision becomes enforceable and, in its reduced form, such provision shall then be enforceable and shall be enforced.

          7.3 Enforceability; Jurisdiction; Arbitration.

          (a) The Company and the Executive intend to and hereby confer jurisdiction to enforce the Restrictive Covenants set forth in Section 6 upon the courts of any jurisdiction within the geographical scope of the Restrictive Covenants. If the courts of any one or more of such jurisdictions hold the Restrictive Covenants wholly unenforceable by reason of breadth of scope or otherwise it is the intention of the Company and the Executive that such determination not bar or in any way affect the Company’s right, or the right of any of its affiliates, to the relief provided above in the courts of any other jurisdiction within the geographical scope of such Restrictive Covenants, as to breaches of such Restrictive Covenants in such other respective jurisdictions, such Restrictive Covenants as they relate to

each jurisdiction’s being, for this purpose, severable, diverse and independent covenants, subject, where appropriate, to the doctrine of res judicata. The parties hereby agree to waive any right to a trial by jury for any and all disputes hereunder (whether or not relating to the Restricted Covenants).

          (b) Any controversy or claim arising out of or relating to this Agreement or the breach of this Agreement (other than a controversy or claim arising under Section 6, to the extent necessary for the Company (or its affiliates, where applicable) to avail itself of the rights and remedies referred to in Section 6.3) that is not resolved by the Executive and the Company (or its affiliates, where applicable) shall be submitted to arbitration in Charlotte, North Carolina in accordance with North Carolina law and the procedures of the American Arbitration Association. The determination of the arbitrator(s) shall be conclusive and binding on the Company (or its affiliates, where applicable) and the Executive and judgment may be entered on the arbitrator(s)’ award in any court having jurisdiction.

          7.4 Notices. Any notice or other communication required or permitted hereunder shall be in writing and shall be delivered personally, telegraphed, telexed, sent by facsimile transmission or sent by certified, registered or express mail, postage prepaid.

          7.7 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NORTH CAROLINA WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW WHICH COULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NORTH CAROLINA.

          7.10 No Duty to Mitigate. Except as may be provided in Section 5.2(c)(ii), the Executive shall not be required to mitigate damages or the amount of any payment provided for under this

          7.14 Existing Agreements. The Executive represents to the Company that she is not subject or a party to any employment or consulting agreement, non-competition covenant or other agreement, covenant or understanding which might prohibit her from executing this Agreement or limit her ability to fulfill her responsibilities hereunder.

of receiving Parachute Payments plus the amount necessary to put the Executive in the same after-tax position (taking into account any and all applicable federal, state and local excise, income or other taxes at the highest applicable rates on such Parachute Payments and on any payments under this Section 7.16) as if no excise taxes had been imposed with respect to Parachute Payments. “Parachute Payment” shall mean a “parachute payment” as defined in Section 280G of the Code. The amount of any payment under this Section 7.16 shall be computed by a certified public accounting firm selected by the Company and reasonably acceptable to the Executive.
