                         EXECUTIVE EMPLOYMENT AGREEMENT
                         ------------------------------

     THIS EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of the 6th
day of March, 2005 by and between Gene Logic Inc., a Delaware corporation (the
"Company"), and V. W. Brinkerhoff, III (the "Executive").

     The Company desires to secure the services of Employee and Employee desires
to perform such services for the Company on the terms and conditions as set
forth in this Agreement.

NOW, THEREFORE, in consideration of the mutual promises made below, the parties
agree as follows:

     1. Employment, Duties and Acceptance.

        1.1 Employment. (a) Effective upon the later of the date of this
agreement or the date the Executive first reports for work for the Company (the
"Effective Date"), the Company shall employ the Executive as Senior Vice
President and General Manager, initially reporting to Mark Gessler. In such
capacity, the Executive shall perform such executive and management duties and
assume such other responsibilities as may be assigned from time to time by the
individual to whom the Executive reports, the Chief Executive Officer ("CEO") of
the Company or anyone else designated by the CEO. The Executive accepts such
employment and shall perform his duties faithfully and to the best of his
abilities.

        (b) The Executive shall devote his full working time and creative
energies to the performance of his duties hereunder and will at all times devote
such additional time and efforts as are reasonably sufficient for fulfilling the
significant responsibilities entrusted to him. So long as such activities, in
the aggregate, do not interfere with the performance by the Executive of his
duties hereunder: (i) the Executive shall be permitted a reasonable amount of
time to supervise his personal, passive investments; and (ii) the Executive
shall be permitted a reasonable amount of time to participate (as board member,
officer or volunteer) in civic, political and charitable activities.

        1.2 Place of Employment. The Executive's principal place of employment
shall be at the Company's headquarters or other Company facility in the
Baltimore-Washington, D.C. metropolitan area (including Montgomery, Howard and
Frederick Counties in Maryland) specified by the individual to whom the
Executive reports, or as otherwise mutually agreed by the parties, subject to
such travel as may be reasonably required by his employment pursuant to the
terms hereof. The Executive shall not be required to relocate outside of the
Baltimore-Washington, D.C. metropolitan area during the Term unless the
Executive so agrees and Company provides relocation benefits reasonably
acceptable to the Executive.

     2. Term of Employment. The Executive's term of employment with the Company
(the "Term") shall commence on the Effective Date and continue thereafter on an
at-will basis until terminated by either party pursuant to Section 4, subject to
certain rights upon termination as provided in Section 4. If Executive's
employment hereunder with the Company is terminated by the Executive or by the
Company, Executive shall thereby be removed from, and Executive agrees to resign
immediately from, all other positions with the Company and its affiliates and
subsidiaries (collectively the "GLGC Group").

     3. Compensation.

        3.1 Salary. As compensation for all services to be rendered pursuant to
this Agreement, the Company shall pay to the Executive during the Term a salary
at the rate of $250,000 per annum (the "Base Salary") less such deductions as
shall be required to be withheld by applicable tax and other laws and
regulations or as otherwise authorized by the Executive. The Base Salary shall
accrue from and after the Effective Date, and shall be payable during the Term,
in arrears in equal periodic installments, not less frequently than
semi-monthly. The Executive's Base Salary shall be reviewed annually and may be
increased based upon various factors, including the evaluation of the
Executive's performance and the compensation policies of the Company in effect
at the time of each such review. The Base Salary shall be prorated for the first
calendar year of employment and for any other year in which Executive is not
employed by the Company for the entire year based on the portion of the year in
which Executive is employed on a full-time basis by the Company.


                                       1

        3.2 Bonus. Executive will be eligible to participate in any bonus plan
established by the Compensation Committee of the Board (the "Compensation
Committee") and generally applicable to officers of the Company. Payment of a
bonus under any such plan will be contingent on achieving such targets and
levels of performance as may be specified by the Compensation Committee. Such
targets and levels of performance may be specified for individuals or groups of
individuals, by department and/or on a company-wide basis. Bonus payments for
any applicable plan will be made on at least an annual basis, subject to prior
approval by the Compensation Committee. The target bonus for Executive for the
Company's fiscal year 2005, which shall be based on achieving 100% of the
targets and levels of performance established by the Compensation Committee,
will be 25% of the base salary specified in Section 3.1 of this Agreement, for a
full calendar year, less applicable withholding, prorated based on the portion
of the year in which Executive is employed by the Company. To receive a bonus
for any period, except as specifically provided in section 4.7, the Executive
must be employed by the Company on a full-time basis as of the last business day
of the period for which the bonus is paid.

        3.3 Stock Options. Upon and subject to approval by the Board of
Directors of the Company or its Compensation Committee, Executive will receive a
stock option grant under the Company's 1997 Equity Incentive Plan (the "Plan")
to acquire 50,000 shares of Company Common Stock at an exercise price equal to
the fair market value per share at date of grant, which will be Executive's
first day of employment hereunder (which for administrative purposes is the
closing price on the last business day preceding the date of grant). The stock
options will vest and become exercisable at the rate of one-forty eighth per
month at the end of each month of employment. The options will have a 10-year
term and be subject to the other terms and conditions of the Plan and the
standard form of stock option grant agreement thereunder. The stock option will
be an incentive stock option under Section 422 of the Internal Revenue Code of
1986, as amended, ("Code") to the maximum extent permitted by the law and the
Plan; any remaining portion of the stock option will be treated as a
Non-Statutory Stock Option.

        3.4 Participation in Benefit Plans. The Executive shall be permitted
during the Term, to the extent eligible, to participate in any group life,
medical, dental, vision, or disability insurance plans, accidental death and
dismemberment plan, 401(k) plan, or similar benefit plans of the Company which
may be available generally to other senior executives of the Company, but
nothing herein shall prevent the Company from changing such benefits from time
to time.

        3.5 Paid Time Off. The Executive shall accrue and may use paid time off
("PTO") in accordance with the Company's policies. PTO accruing in the first
calendar year of employment and in any other year in which Executive is not
employed by the Company for the entire year shall be prorated based on the
portion of the year in which Executive is employed by the Company.

        3.6 Holidays. The Executive shall be eligible for holidays in accordance
with the Company's policy and schedule.

        3.7 Expenses. In accordance with the Company's policies, the Executive
will be reimbursed for all ordinary, necessary and reasonable business expenses
(including, without limitation, travel, meetings, dues, subscriptions, fees,
educational expenses, and expenses incurred for operation of mobile telephones,)
actually incurred or paid by the Executive during the Term in the proper
performance of the Executive's services under this Agreement, upon presentation
of expense statements or vouchers or such other supporting information as the
Board may reasonably require.

        3.8 Tax/Financial Planning. The Executive shall be reimbursed in an
amount not in excess of $5,000 in the aggregate per year for tax return
preparation and certain financial planning advice in accordance with the
Company's policies.

        3.9. Change of Control. If so designated by the Board, the Executive
shall be included in the Company's Executive Severance Plan (the
"Change-of-Control Severance Plan"), which may provide certain benefits if the
Executive's employment is terminated as a result of a change in control of the
Company.


                                       2

        3.10 Withholding. The Company is authorized to withhold from the amount
of any Base Salary and bonuses and any other payments or benefits paid or
provided to or for the benefit of the Executive, all sums authorized by the
Executive or required to be withheld by law, court decree, or executive order,
including (but not limited to) such things as income taxes, employment taxes,
and employee contributions to fringe benefit plans sponsored by the Company.

     4. Termination.

        4.1 General. The employment of the Executive hereunder may be terminated
as provided in this Section 4.

        4.2 Termination Upon Mutual Agreement. The Company and the Executive
may, by mutual written agreement, terminate this Agreement and/or the employment
of the Executive at any time.

        4.3 Death or Disability of Executive.

        (a) The employment of the Executive hereunder shall terminate upon (i)
the death of the Executive, and (ii) at the option of the Company upon not less
than thirty (30) days prior written notice to the Executive or his personal
representative or guardian, if the Executive suffers a Total Disability (as
defined in Section 4.3(b) below).

        (b) For purposes of this Agreement, "Total Disability" shall mean (i) if
the Executive is subject to a legal decree of incompetency (the date of such
decree being deemed the date on which such disability occurred), or (ii) the
written determination by a physician selected by the Company that, because of a
medically determinable disease, injury or other physical or mental disability,
the Executive is substantially unable to perform his essential duties, without
reasonable accommodation, and that such disability has lasted for the
immediately preceding ninety (90) days and is, as of the date of determination,
reasonably expected to last an additional ninety (90) days or longer after the
date of determination. If requested by the Company, Executive agrees to appear
at a medical examination by a physician selected by the Company and to furnish
to such physician such medical information as is needed for a determination
under this Section 4.3(b). Nothing in this provision is intended to restrict
rights or obligations under the Americans with Disabilities Act or other
applicable law.

        (c) Any leave on account of illness or temporary disability which is
short of Total Disability shall not constitute a breach of this Agreement by the
Executive and in no event shall any party be entitled to terminate this
Agreement for Cause (as defined below) due to any such leave. All physicians
selected hereunder shall be Board certified in the specialty most closely
related to the nature of the disability alleged to exist.

        4.4 Termination For Cause. The Company may, upon action of the Board,
and upon written notice to the Executive specifying in reasonable detail the
reason therefore, terminate the employment of the Executive at any time for
Cause (as defined in Attachment A); provided, however, that if the reason for
termination for Cause is susceptible of cure as determined by the Company, the
Executive shall have a period of fifteen (15) business days after such written
notice to effect a cure satisfactory to the Company.

        4.5 Termination Without Cause. The Company may also terminate the
employment of the Executive without Cause upon 30 days advance written notice to
the Executive, which termination shall constitute a "Termination Without Cause".
Termination without Cause shall not include a termination due to death or Total
Disability.

        4.6 Termination by Executive. The Executive may resign (and thereby
terminate his employment under this Agreement) at any time, by giving the
Company not less than thirty (30) days' prior written notice to the Company, but
the Company after receipt of such notice, may waive all or part of such notice
period.

        4.7 Payments Upon Termination.

        (a) (i) If Executive's employment is terminated by the Company without
Cause, the Company shall pay the Executive six (6) months Base Salary.
Notwithstanding anything to the contrary above, in the event of a change of
control of the Company, if the Executive is eligible for and has met the
conditions for receiving cash severance benefits under the Change-of-Control
Severance Plan, then the provisions set forth in such plan shall apply in lieu
of payments under this subsection (i).

            ii) The Company shall have no further liability to the Executive
pursuant to this Agreement, in the event of termination by the Company in a
Termination Without Cause or a termination by the Executive except as set forth
in this Section 4.7(a), including, without limitation, any liability to pay the
Executive any severance, bonus or any other compensation.

            iii) The Company also waives, releases and remises (A) any
obligation or duty under applicable law on the part of the Executive to seek or
obtain other engagements or employment or to otherwise mitigate any damages to
which the Executive may be entitled by reason of any termination of this
Agreement; and (B) any right in or claim to any remuneration or compensation
received by Executive pursuant to any engagements or employment subsequent to
the termination of this Agreement. Any payments made under this Section 4.7(a)
or the Change-of-Control Severance Plan may be conditioned upon execution by
Executive of a release of claims arising from or connected with his employment
in such form as may be specified by the Company (excluding from any such release
any rights Executive may have to indemnification or insurance coverage with
respect to his actions while employed by the Company under Directors and
officers or other insurance maintained by the Company or under the Company's
indemnification policies and applicable law concerning indemnification).

        (b) If the Executive's employment is terminated (i) by the Company for
Cause, or (ii) by the Executive, then the Company shall have no duty to make any
payments or provide any benefits to the Executive pursuant to this Agreement
other than payment of the amount of the Executive's Base Salary and benefits
accrued through the date of termination of his employment.

        (c) Upon termination of Executive's employment for death or Total
Disability, the Company shall pay to the Executive, or to his guardian or
personal representative, as the case may be, in addition to any insurance or
disability benefits to which he may be entitled under applicable insurance and
benefit programs contemplated by Section 3.4 and then in effect, all amounts
accrued or vested prior to such termination; provided, however, if cash
severance benefits are payable under the Change-of-Control Severance Plan as a
result of such termination, then the provisions set forth in such plan shall
apply in lieu of the foregoing. The Company shall have no further liability to
the Executive, guardian or personal representative pursuant to this Agreement,
including, without limitation, any liability to pay the Executive, guardian or
personal representative any severance, bonus or any other compensation.

        4.8 No Disparaging Comments Upon Termination.

        Upon termination of this Agreement and thereafter, the Executive shall
refrain from making any disparaging remarks about the businesses, services,
products, stockholders, officers, directors or other personnel of the GLGC
Group.

     5. Certain Covenants of the Executive.

        5.1 Necessity for Covenants. The Executive acknowledges that (i) the

Group; (iii) his employment will give him access to confidential information and

essential to protect the business and goodwill of the GLGC Group. To induce the
Company to enter into this Agreement and pay the compensation and other benefits
at the levels requested by the Executive, the Executive enters into the
following covenants:

        (e) "Term" means the term of employment as specified in Section 2 hereof

        5.3 Restrictive Covenants.

            5.3.1 Restrictions. During the Term and for a period of two (2)
years after the date (the "Termination Date") the Executive's employment
hereunder is terminated (the "Restricted Period") regardless of whether such
termination is voluntary or involuntary, with or without Cause or by
resignation, the Executive shall not, directly or indirectly, for himself or on
behalf of any other person, firm, corporation or other entity, whether as a
principal, agent, employee, stockholder, partner, officer, member, adviser,
consultant, director, sole proprietor, or otherwise:

        (a) call upon or solicit any Business Contact for the purpose of
persuading the Business Contact to engage the Executive or any other person,
firm, corporation or other entity to provide goods or services which are the
same as or similar to those the GLGC Group provided or proposed to provide to
the Business Contact or to engage the Business Contact to provide goods or
services which are the same as or similar to those the Business Contact provided
to the GLGC Group to any other person, firm, corporation or other entity;

        (b) solicit, participate in or promote the solicitation of any person

            5.3.2 Severability of Covenants. The Executive acknowledges and
agrees that the Restrictive Covenants are reasonable and valid in geographical
and temporal scope and in all respects. If any court determines that any of the
Restrictive Covenants, or any part thereof, is invalid or unenforceable, the
remainder of the Restrictive Covenants shall not thereby be affected and shall
be given full effect, without regard to the invalid portions.

            5.3.3 Blue-Penciling. If any court determines that any of the
Restrictive Covenants, or any part thereof, is unenforceable because of the
duration or geographic scope of such provision, such court shall have the power
to reduce the duration or scope of such provision, as the case may be, and, in
its reduced form, such provision shall then be enforceable and shall be
enforced. If any such court declines to so revise such covenant, the parties
agree to negotiate in good faith a modification that will make such duration or
scope enforceable.

        5.4 Rights and Remedies Upon Breach. If the Executive breaches, or
threatens to commit a breach of, any of the provisions of Section 5.3 (the
"Restrictive Covenants"), the Company shall, in addition to its right
immediately to terminate this Agreement for Cause, have the right and remedy
(which right and remedy shall be independent of others and severally
enforceable, and which shall be in addition to, and not in lieu of, any other
rights and remedies available to the Company under law or in equity) to have the
Restrictive Covenants specifically enforced by any court having jurisdiction, it
being acknowledged and agreed that any such breach or threatened breach could
cause irreparable injury to the Company and that money damages may not provide
an adequate remedy to the Company.

     6 Representations of Executive. The Executive represents and warrants that:
(a) his employment by the Company will not (i) violate any non-disclosure
agreements, covenants against competition, or other restrictive covenants or
agreements made by the Executive with, to or for the benefit of any previous
employer or partner, or (ii) violate or constitute a breach or default under,
any statute, law, judgment, order, decree, writ, injunction, deed, instrument,
contract, lease, license or permit to which the Executive is a party or by which
the Executive is bound; (a) there is no litigation, proceeding or investigation
of any nature (either civil or criminal) which is pending or, to the best of the
Executive's knowledge, threatened against or affecting the Executive or which
would adversely affect his ability to substantially perform the duties herein;
and (b) he has received or been given the opportunity to review the provisions
of this Agreement, and the meaning and effect of each provision, with
independent legal counsel of the Executive's choosing.

     7. Confidentiality and Proprietary Inventions Agreement. As a condition to
his employment by the Company, the Executive agrees to enter into and be bound
by the provisions set forth in the Company's Proprietary Information and
Inventions Agreement, which is expressly incorporated by reference hereto.

     8. Dispute Resolution.

        8.1 Arbitration Policy. Subject to the Company's right to seek
injunctive or other equitable relief as specified in Section 5.4 of this
Agreement or in the Proprietary Information and Inventions Agreement, the
Parties agree that arbitration is the required and exclusive forum for the
resolution of any and all disputes between them, including claims arising under
statute, common law, or this Agreement. This mandatory arbitration provision
includes without limitation any claims or actions under Title VII of the Civil
Rights Act of 1964, the Civil Rights Act of 1866 ("Section 1981"), the Americans
with Disabilities Act, the Family and Medical Leave Act, the Age Discrimination
in Employment Act, the Fair Labor Standards Act, the Equal Pay Act, the Employee
Retirement Income Security Act, and any other federal, state or local statute,
law or regulation regarding employment, employment discrimination, terms and
conditions of employment, compensation or termination of employment. This
mandatory arbitration provision includes any dispute between the Executive and
the Company or its parents, subsidiaries and affiliates, and its and their
current and former officers, directors, employees and agents.


                                       6
<PAGE>

        Any covered dispute must be submitted to arbitration in accordance with
the National Rules for the Resolution of Employment Disputes of the American
Arbitration Association. Any such arbitration will be conducted in Montgomery
County, Maryland, and will be decided in accordance with and determined by the
laws of the State of Maryland and/or applicable federal law. The Executive
specifically agrees that the Company may seek specific performance of this
provision, as well as other injunctive relief, from the state or federal courts
in Maryland. The arbitrator shall not have the authority to award punitive
damages, costs or attorneys' fees to either Party except where expressly
provided for by the applicable law.

        Except as otherwise provided by applicable law, the administrative costs
of the arbitration (filing fees, cost for the arbitration site, other AAA fees,
arbitrator's fee) shall be divided equally between the parties. The fees and
expenses of any witness shall be paid by the Party requiring the presence of
such witness. Each Party shall bear its own costs and expenses in all other
respects. The resolution of any dispute achieved through such arbitration shall
be final and binding and enforceable by a court of competent jurisdiction.

        8.2 No Jury Trial. NEITHER PARTY SHALL ELECT A TRIAL BY JURY IN ANY
ACTION, SUIT, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN ANY WAY CONNECTED
WITH THIS AGREEMENT.

        8.3 Personal Jurisdiction. Both parties agree to submit to the
jurisdiction and venue of the state courts in Montgomery County, Maryland as to
matters involving enforcement of this Agreement, including any award under an
arbitration proceeding.

                              Definition of "Cause"



"Cause" shall mean

(i)   commission of an act or omission which the Company determines would
      constitute a felony or a misdemeanor which, in the Company's reasonable
      opinion, could have a material adverse effect on the Company's business,
      financial condition, prospects or reputation or the Executive's
      performance of his duties, under the laws of the United States or of any
      state or a crime involving moral turpitude, including, but not limited to,
      fraud, theft, embezzlement or any crime that results in or is intended to
      result in personal enrichment at the expense of the Company;
(ii)  material breach by the Executive of any agreement entered into between the
      Executive and the Company;
(iii) willful misconduct by the Executive or gross negligence of the Executive
      which could have a material adverse impact on the Company;
(iv)  a material failure of the Executive in the performance of the Executive's
      duties provided that, if susceptible of cure as determined by the Company,
      notice is provided and Executive does not cure such failure within fifteen
      (15) business days after the date of such notice in a manner reasonably
      satisfactory to the Company;
(v)   the violation by the Executive of the restrictive covenants in Section 5.3
      hereof or the provisions of the Proprietary Information and Inventions
      Agreement; or
(vi)  engagement in any activity that constitutes a material conflict of
      interest with the Company.

With respect to any criminal act, the Company may base such a determination on
facts available to it or on an arrest or charges by an appropriate government
authority and may, at its option, suspend the Executive without pay in lieu of
immediate termination in the event of any criminal charges, pending additional
information, criminal conviction or other action.
