                          SALARY CONTINUATION AGREEMENT

     THIS AGREEMENT dated as of October 15, 2002 is made by and between GenVec,
Inc. (the "Company"), and Paul H. Fischer (the "Executive").

     WHEREAS the Company considers it essential to its best interests and to the
best interests of its stockholders to foster the continuous employment of its
key management personnel; and

     WHEREAS the Company has determined that appropriate steps should be taken
to reinforce and encourage the continued attention and dedication of the
Company's management, including the Executive, to their assigned duties.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained, the Company and the Executive hereby agree as follows:

     1.   DEFINED TERMS. Capitalized terms shall have the meaning provided in
this Agreement.

     2.   TERM OF AGREEMENT. Subject to section 4.15, this Agreement shall
become effective as of the date hereof and shall remain in effect indefinitely
thereafter provided, however, that the Company may terminate this Agreement by
giving the Executive at least 24 months advance written notice of such
termination.

     3.   SEVERANCE BENEFITS.

     (a) In order to induce the Executive to continue to serve as an employee of
the Company, the Company agrees, under the terms and conditions set forth
herein, that the Company shall provide to the Executive the benefits described
in Sections 3.1 and 3.2 below (the "Severance Benefits"), if the Company
terminates the Executive's employment without Cause and other than by reason of
death or disability.

     (b) For purposes of this Agreement, Cause shall mean:

                 (a)   the willful and continued failure of the Executive to
substantially perform the Executive's duties with the Company (other than any
such failure resulting from incapacity due to physical or mental illness);

                 (b)   the willful engaging by the Executive in illegal conduct
or gross misconduct which is materially and demonstrably injurious to the
Company;

                                      - 1 -
<Page>

                 (c)   personal dishonesty or breach of fiduciary duty to the
Company that in either case results or was intended to result in personal profit
to the Executive at the expense of the Company; or

                 (d)   willful violation of any law, rule or regulation (other
than traffic violations, misdemeanors or similar offenses) or cease-and-desist
order, court order, judgment or supervisory agreement, which violation is
materially and demonstrably injurious to the Company.

For purposes of the preceding clauses, no act or failure to act, on the part of
the Executive, shall be considered "willful" unless it is done, or omitted to be
done, by the Executive in bad faith and without reasonable belief that the
Executive's action or omission was in the best interests of the Company. Any
act, or failure to act, based upon prior approval given by the Board or based
upon the advice of counsel for the Company, shall be conclusively presumed to be
done, or omitted to be done, by the Executive in good faith and in the best
interests of the Company.

          3.1    SEVERANCE PAYMENT. In lieu of any further salary payments to
the Executive for periods subsequent to the Executive's date of termination of
employment with the Company (the "Date of Termination"), the Company shall
continue to pay to the Executive the Executive's base salary for a 24 month
period. Such continued base salary shall be paid in a manner consistent with the
then current payroll practices of the Company.

          3.2    CONTINUED BENEFITS. For a 24 month period beginning on the
Executive's Date of Termination (the "Benefits Period"), the Company shall
provide Executive with life insurance and health insurance (together, "Welfare
Benefits") under the Company's employee benefit plans and policies. During the
Benefits Period, the Executive shall be entitled to elect to change Executive's
level of coverage and/or Executive's choice of coverage options (such as the
Executive only or family medical coverage) with respect to the Welfare Benefits
to be provided by the Company to the Executive to the same extent that active
employees of the Company are permitted to make such changes; provided, however,
that in the event of any such changes, the Executive shall pay the amount of any
cost increase that would actually be paid by an active employee of the Company
by reason of making the same changes in Executive's level of coverage or
coverage options. In the event that the Executive becomes employed by a new
employer and is eligible to receive health insurance and/or other welfare
benefits ("New Coverage"), the Welfare Benefits coverage provided under this
Section 3.2 shall be secondary to such New Coverage.

          3.3    PRO RATA BONUS. The Company shall pay to the Executive a lump
sum cash payment equal to the product of (x) the bonus paid to the Executive for
the fiscal year preceding the Executive's Date of Termination, divided by twelve
(12) and multiplied by (y) the number of months of service during the year of
termination.

     4.   MISCELLANEOUS.

                                      - 2 -

          4.1    NON-DISPARAGEMENT. Executive agrees that Executive will not
make or publish any adverse, disparaging, untrue, or misleading statement or
comment about the Company or any of its officers, directors, employees, or
agents. The Company agrees that it will not make or publish any adverse,
disparaging, untrue, or misleading statement or comment about Executive.

          4.2    NON-COMPETE.

          (a) Executive acknowledges that, as a result of Executive's positions
with the Company Executive has access to information with respect to the
development, implementation and management of the Company's business strategies
and plans, including those which involve the Company's finances, manufacturing,
marketing, operations, industrial relations and acquisitions. Accordingly,
during the period of Executive's employment with the Company and for a period of
24 months thereafter, Executive agrees that Executive shall not, directly or
indirectly, in any capacity, carry on, be engaged in, assist, consult for or
have any financial or other interest in any business which is in competition
with the business of the Company (provided that a financial interest of not more
than two percent (2%) in any company which is publicly traded and whose shares
are listed on a national stock exchange or as quoted on NASDAQ shall be
permitted). In addition, Executive shall not, on Executive's behalf or on behalf
of any firm, partnership, corporation or any other person or entity, directly or
indirectly, during the twelve month period following Executive's termination of
employment from the Company, for any reason whatsoever, solicit or offer
employment to any person who has been employed by the Company at any time during
the twelve months immediately preceding such solicitation. For purposes of this
Section 4.2, a business shall be deemed to be in competition with the business
of the Company if it is principally involved or if it has proposed to become
principally involved in the purchase, sale or other dealing in any property or
product or the rendering of any service purchased, sold, dealt in or rendered,
by the Company as a material part, or expected material part, of the business of
the Company.

          (b)    The Executive and the Company agree that this covenant not to
compete and the covenant not to solicit are reasonable covenants under the
circumstances, Executive has been adequately compensated for such covenants, and
further agree that if in the opinion of any court of competent jurisdiction such
restraint is not reasonable in any respect, such court shall have the right,
power and authority to excise or modify such provision or provisions of this
covenant as to the court shall appear not reasonable and to enforce the
remainder of the covenant as so amended.

          4.3    NONDISCLOSURE. During the Executive's employment with the
Company and thereafter, the Executive shall not disclose or use in any way any
confidential business or technical information or trade secret acquired in the
course of such employment, other than (i) information that is generally known in
the Company's industry or acquired from public sources, (ii) as required in the
course of such

                                      - 3 -
<Page>

employment, (iii) as required by any court, supervisory authority administrative
agency or applicable law, or (iv) with the prior written consent of the Company.

          4.4    NO MITIGATION. The Company agrees that, if the Executive's
employment by the Company is terminated in a manner that results in the
Executive becoming entitled to the Severance Benefits, the Executive shall not
be required to seek other employment or to attempt in any way to reduce any
amounts payable to the Executive by the Company pursuant to this Agreement.
Except to the extent provided in Section 3.2 hereof, the amount of any payment
or benefit provided for under this Agreement shall not be reduced by any
compensation earned by the Executive as the result of employment by another
employer or by retirement benefits.

          4.5    SUCCESSORS. In addition to any obligations imposed by law upon
any successor to the Company, the Company shall be obligated to require any
successor (whether direct or indirect and whether by merger, consolidation,
operation of law, or otherwise) to the Company to expressly assume this
Agreement and the obligations hereunder. In the event of such a succession,
references to the "Company" herein shall thereafter be deemed to include such
successor.

          4.6    DEATH. This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive shall die while any amount or benefit would still be payable or
required to be provided to the Executive hereunder if the Executive had
continued to live, all such amounts and benefits, unless otherwise provided
herein, shall be paid or provided in accordance with the terms of this Agreement
to the executors, personal representatives or administrators of the Executive's
estate.

          4.7    NOTICES. For the purpose of this Agreement, notices and all
other communications shall be in writing and shall be deemed to have been duly

                           CHANGE IN CONTROL AGREEMENT

     THIS AGREEMENT dated as of October 15, 2002 is made by and between GenVec,
Inc. (the "Company"), and Paul Fischer (the "Executive").

     WHEREAS the Company considers it essential to its best interests and to the
best interests of its stockholders to foster the continuous employment of its
key management personnel; and

     WHEREAS the Company recognizes that the possibility of a Change in Control
(as defined in Section 9.6 hereof) exists, as in the case of any publicly-held
corporation, and that such possibility, and the uncertainty and questions which
it may raise among management, may result in the departure or distraction of
management personnel to the detriment of the Company and its stockholders; and

     WHEREAS the Company has determined that appropriate steps should be taken
to reinforce and encourage the continued attention and dedication of members of
the Company's management, including the Executive, to their assigned duties
without distraction in the face of potentially disturbing circumstances arising
from the possibility of a Change in Control;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained, the Company and the Executive hereby agree as follows:

     1.   DEFINED TERMS. Definitions of certain capitalized terms used in this
Agreement are provided in Section 9 and elsewhere in this Agreement.

     2.   TERM OF AGREEMENT. This Agreement shall become effective on the date
hereof and shall remain in effect indefinitely thereafter; provided, however,
that (a) except as provided in clause (b) of this sentence, either the Company
or the Executive may terminate this Agreement by giving the other party at least
one (1) year advance written notice of such termination, and (b) if a Change in
Control shall have occurred during the term of this Agreement, this Agreement
may not be terminated until all obligations of either party hereto have been
performed in full and the Coverage Period has expired without the occurrence of
a Triggering Event. Notwithstanding the foregoing, this Agreement shall
terminate upon the Executive's Disability or death, except as to obligations of
the Company hereunder arising from a Change in Control and/or a termination of
the Executive's employment that, in either case, occurred prior to his
Disability or death.

     3.   AGREEMENT OF THE COMPANY. In order to induce the Executive to remain
in the employ of the Company, the Company agrees, under the terms and conditions
set forth herein, that, upon the occurrence of both a Change in Control and a
Triggering

                                      - 1 -
<Page>

Event during the term of this Agreement, the Company shall provide to the
Executive the benefits described in this Section 3 (the "Severance Benefits").

          3.1    SEVERANCE PAYMENT. In lieu of any further salary payments to
the Executive for periods subsequent to the Date of Termination, the Company
shall pay to the Executive a lump sum severance payment, in cash, without
discount, equal to the sum of (i) the product of (x) 24 months and (y) the
Executive's Monthly Base Salary and (ii) the Executive's Average Bonus divided
by 12 and multiplied by 24 months.

          3.2    CONTINUED BENEFITS. For a 24 month period after the Date of
Termination (the "Benefits Period"), the Company shall provide the Executive
with life insurance and health insurance (together, "Welfare Benefits")
substantially similar in all respects to those which the Executive was receiving
immediately prior to the Notice of Termination. During the Benefits Period, the
Executive shall be entitled to elect to change his level of coverage and/or his
choice of coverage options (such as the Executive only or family medical
coverage) with respect to the Welfare Benefits to be provided by the Company to
the Executive to the same extent that actively employed officers of the Company
are permitted to make such changes; provided, however, that in the event of any
such changes, the Executive shall pay the amount of any cost increase that would
actually be paid by an actively employed officer of the Company by reason of
making the same changes in his level of coverage or coverage options. In the
event that the Executive becomes employed by a new employer and is eligible to
receive health insurance and/or other welfare benefits ("New Coverage"), the
Welfare Benefits coverage provided under this Section 3.2 shall be secondary to
such New Coverage.

          3.3    ACCRUED COMPENSATION AND OTHER BENEFITS. To the extent not
theretofore paid or provided, the Company shall timely pay or provide to
Executive his Accrued Compensation and any Other Benefits to which Executive is
entitled.

          3.4    BONUS.

          (a) TERMINATION YEAR BONUS. The Company shall pay to the Executive a
lump sum cash payment equal to: (x) the product of (i) the Executive's highest
annual base salary in effect during the one (1) year period preceding the
Executive's Date of Termination divided by twelve (12) and (ii) the Executive's
Target Percentage (determined as of the Date of Termination), multiplied by (y)
the number of months (including fractions thereof) elapsed from the first day of
the Termination Year to the Date of Termination.

          (b) PRECEDING FISCAL YEAR BONUS. To the extent that as of the Date of
Termination the Company has not yet determined and paid to the Executive any
incentive award to which the Executive is entitled under any Company incentive
plan with respect to the fiscal year preceding the Termination Year, the Company
shall also pay to the Executive a lump sum cash payment at a minimum equal to
the product of (x) the Executive's highest annual base salary in effect during
such fiscal year and (y) the Executive's highest Target Percentage in effect
during such fiscal year.

                                      - 2 -
<Page>

     4.   GROSS-UP PAYMENT; CERTAIN LIMITATIONS ON PAYMENTS AND BENEFITS.

     In the event that (a) the Executive becomes entitled to the Severance
Benefits or any other benefits or payments in connection with a Change in
Control or the termination of the Executive's employment, whether pursuant to
the terms of this Agreement or otherwise (collectively, but excluding the amount
of any Gross-Up Payment under this Section 4, the "Total Benefits"), and (b) any
of the Total Benefits will be subject to the Excise Tax, then the Total Benefits
shall be reduced to the extent necessary so that no portion of the Total
Benefits is subject to the Excise Tax; provided, however that if the amount of
such reduction would exceed $10,000, no such reduction shall be made and the
Company shall instead pay to the Executive an additional amount (the "Gross-Up
Payment") equal to the Excise Tax on the Total Benefits plus an amount equal to
any federal income taxes and FICA and Medicare withholding taxes payable upon
such Gross-Up Payment. For purposes of determining the amount of such Excise
Tax, the amount of the Total Benefits that shall be treated as subject to the
Excise Tax shall be equal to (i) the Total Benefits, minus (ii) the amount of
such Total Benefits that, in the opinion of tax counsel selected by the Company
and reasonably acceptable to the Executive ("Tax Counsel"), are not excess
parachute payments (within the meaning of Section 280G(b)(1) of the Code).

     5.   TIMING OF PAYMENTS. The payments provided for in Sections 3.1 and 4
shall be made on the Date of Termination; provided, however, that if the amounts
of such payments cannot be finally determined on or before such day, the Company
shall pay to the Executive on such day an estimate, as determined in good faith
by the Company, of the minimum amount of such payments and shall pay the
remainder of such payments (together with interest at the rate provided in
Section 1274(b)(2)(B) of the Code from the Date of Termination to the payment of
such remainder) as soon as the amount thereof can be determined but in no event
later than the thirtieth (30th) day after the Date of Termination. In the event
that the amount of the estimated payments exceeds the amount subsequently
determined to have been due, such excess shall constitute a loan by the Company
to the Executive, payable on the fifth (5th) business day after demand by the
Company (together with interest at the rate provided in Section 1274(b)(2)(B) of
the Code from the Date of Termination to the repayment of such excess).

     6.   REIMBURSEMENT OF LEGAL COSTS. The Company shall pay to the Executive
all reasonable legal fees and expenses incurred by the Executive as a result of
a bona fide dispute regarding the application of any provision of this Agreement
including all such fees and expenses, if any, incurred (a) in disputing any
Notice of Termination under Section 7.1 hereof, (b) in seeking to obtain or
enforce any right or benefit provided by this Agreement or (c) in connection
with any tax audit or proceeding to the extent attributable to the application
of Section 4999 of the Code to any payment or benefit provided hereunder. Such
payments shall be made within five (5) business days after delivery of the
Executive's respective written requests for payment accompanied with such
evidence of fees and expenses incurred as the Company reasonably may require.

                                      - 3 -

     7.   TERMINATION PROCEDURES.

          7.1    NOTICE OF TERMINATION. After a Change in Control, any
termination of the Executive's employment (other than by reason of death) must
be preceded by a written Notice of Termination from the terminating party to the
other party hereto in accordance with Section 8.5 hereof. For purposes of this
Agreement, a "Notice of Termination" shall mean a notice which shall (a) specify
the date of termination (the "Date of Termination") which shall not be more than
sixty (60) days from the date such Notice of Termination is given, (b) indicate
the notifying party's opinion regarding the specific provisions of this
Agreement that will apply upon such termination and (c) set forth in reasonable
detail the facts and circumstances claimed to provide a basis for the
application of the provisions indicated. Termination of the Executive's
employment shall occur on the specified Date of Termination even if there is a
dispute between the parties relating to the provisions of this Agreement
applicable to such termination.

          7.2    DISPUTE CONCERNING APPLICABLE TERMINATION PROVISIONS. If within
thirty (30) days of receiving the Notice of Termination the party receiving such
notice notifies the other party that a dispute exists concerning the provisions
of this Agreement that apply to such termination, the dispute shall be resolved
either by mutual written agreement of the parties or by expedited commercial
arbitration under the rules of the American Arbitration Association. The parties
shall pursue the resolution of such dispute with reasonable diligence. Within
five (5) days of such a resolution, any party owing any payments pursuant to the
provisions of this Agreement shall make all such payments together with interest
accrued thereon at the rate provided in Section 1274(b)(2)(B) of the Code.

     8.   MISCELLANEOUS.

          8.1    NO MITIGATION. The Company agrees that, if the Executive's
employment by the Company is terminated in a manner that results in the payment
of Severance Benefits hereunder, the Executive shall not be required to seek
other employment or to attempt in any way to reduce any amounts payable to the
Executive by the Company pursuant to this Agreement. Further, the amount of any
payment or benefit provided for under this Agreement shall not be reduced by any
compensation earned by the Executive as the result of employment by another
employer, by retirement benefits, by offset against any amount claimed to be
owed by the Executive to the Company, or otherwise.

          8.2    SUCCESSORS. In addition to any obligations imposed by law upon
any successor to the Company, the Company shall be obligated to require any
successor (whether direct or indirect, by purchase, merger, consolidation,
operation of law, or otherwise) to all or substantially all of the business
and/or assets of the Company to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession had taken place; in the event of
such a succession, references to the "Company" herein shall thereafter be deemed
to include such successor. Failure of the Company to obtain such

                                      - 4 -
<Page>

assumption and agreement at or prior to the effectiveness of any such succession
shall be a breach of this Agreement and shall entitle the Executive to terminate
his employment and thereafter to receive Severance Benefits, except that, for
purposes of implementing the foregoing, the date on which any such succession
becomes effective shall be deemed the Date of Termination.

          8.3    INCOMPETENCY. Any benefit payable to or for the benefit of the
Executive, if legally incompetent, or incapable of giving a receipt therefor,
shall be deemed paid when paid to the Executive's guardian or to the party
providing or reasonably appearing to provide for the care of such person, and
such payment shall fully discharge the Company.

          8.4    DEATH. This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive shall die while any amount would still be payable to the Executive
hereunder (other than amounts which, by their terms, terminate upon the death of
the Executive) if the Executive had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to the executors, personal representatives or administrators of the
Executive's estate.

          8.5    NOTICES. For the purpose of this Agreement, notices and all
other communications provided for in the Agreement shall be in writing and shall
be deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed to the
respective addresses set forth below, or to such other address as either party
may have furnished to the other in writing in accordance herewith, except that
notice of change of address shall be effective only upon actual receipt:
