intended to secure for Digene Corporation (the “Company”) and its stockholders the benefits
of the incentive inherent in common stock ownership by consultants providing services to the
Company and to afford such persons the opportunity to obtain or increase their proprietary interest
in the Company on a favorable basis and thereby have an opportunity to share in its success.

     1.2 Effective Date. This Plan shall be effective on and after September 9, 1997.

     1.3 Definitions. Throughout this Plan, the following terms shall have the meanings
indicated:

the Company and its subsidiaries taken as a whole; or (c) the acquisition by any third party or
group of third parties acting in concert, of beneficial ownership (within the meaning of Rule 13d-3

amended) of shares of voting stock of the Company, the result of which in the case of any
transaction described in clauses (a), (b) and (c) above is that immediately after the transaction
the stockholders of the Company immediately before the transaction, other than the acquiror, own
less than fifty percent (50%) of the combined voting power of the outstanding voting securities
entitled to vote generally in the election of directors of the surviving or resulting corporation

shall not be deemed to have occurred if the Consultant has become

2

 

an employee, officer or director of the Company in which event a Termination of Engagement
shall occur only upon the termination (whether voluntary or involuntary) of all positions with the
Company.

ARTICLE II

ADMINISTRATION

     2.1 Committee Administration. This Plan and the Options granted hereunder shall be
interpreted, construed and administered by the Committee in its sole discretion. A person who has
been granted Options under the Plan may appeal to the Committee in writing any decision or action
of the Committee with respect to the Plan that adversely affects such person. Upon review of such
appeal and in any other case where the Committee has acted with respect to the Plan, the
interpretation and construction by the Committee of any provisions of this Plan or of any Option
shall be conclusive and binding on all parties.

     2.2 Committee Composition. The Committee shall consist of not less than two persons
who shall be members of the Board and shall be subject to such terms and conditions as the Board
may prescribe. Each Committee member shall be a “Non-Employee Director” within the meaning of Rule
16b-3 promulgated under the Exchange Act. Once designated, the Committee shall continue to serve
until otherwise directed by the Board. From time to time, the Board may increase the size of the
Committee and appoint additional members thereof, remove members (with or without cause) and
appoint new members in substitution therefor, fill vacancies however caused and remove all members
of the Committee.

     A majority of the entire Committee shall constitute a quorum, and the action of a majority of
the members present at any meeting at which a quorum is present shall be deemed the action of the
Committee. In addition, any decision or determination reduced to writing and signed by all of the
members of the Committee shall be fully as effective as if it had been made by a majority vote at a
meeting duly called and held. Subject to the provisions of this Plan and the Company’s bylaws, and
to any terms and conditions prescribed by the Board, the Committee may make such additional rules
and regulations for the conduct of its business as it shall deem advisable. The Committee shall
hold meetings at such times and places as it may determine.

     2.3 Committee Powers. The Committee shall have authority to grant Options pursuant to
an Option Agreement providing for such terms (not inconsistent with the provisions of this Plan) as
the Committee may consider appropriate. Such terms shall include, without limitation, as
applicable, the number of shares, the Option price, the medium and time of payment, the term of
each grant and any vesting requirements and may include conditions (in addition to those contained
in this Plan) on the exercisability of all or any part of an Option. Notwithstanding any such
conditions, the Committee may, in its discretion, at any time on or after the date of grant,
accelerate the time at which any Option may be exercised. In addition, the Committee shall have
complete discretionary authority to prescribe the form of Option Agreements; to adopt, amend and
rescind rules and regulations pertaining to the administration of the Plan; and to make all other
determinations necessary or advisable for the administration of this Plan. The express grant in
the Plan of any specific power to the Committee shall not be

3

 

construed as limiting any power or authority of the Committee. All expenses of administering this
Plan shall be borne by the Company.

     2.4 Limitation on Receipt of Options by Committee Members. No person while a member
of the Committee shall be eligible to be granted Options under this Plan, but a member of the
Committee may be granted and may exercise options to purchase stock granted under other plans of
the Company, and a member of the Committee may exercise Options granted under this Plan prior to
his or her becoming a member of the Committee.

     2.5 Good Faith Determinations. No member of the Committee or other member of the
Board shall be liable for any action or determination made in good faith with respect to this Plan
or any Option granted hereunder.

ARTICLE III

ELIGIBILITY; SHARES SUBJECT TO PLAN

     3.1 Eligibility. The Committee shall from time to time determine and designate
Consultants to receive Options under this Plan, the number of Options to be granted to each such
Consultant, the formula or other basis on which such Options shall be granted to Consultants and
any condition or conditions to the exercise of such Options consistent with the terms of this Plan.
In making any such grant, the Committee may take into account the nature of services rendered by a
Consultant, commissions, fees or other compensation paid by the Company to the Consultant, the
capacity of the Consultant to contribute to the success of the Company and other factors that the
Committee may consider relevant.

     3.2 Shares Subject to this Plan. Subject to the provisions of Section 4.1(e)
(relating to adjustment for changes in Common Stock), the maximum number of shares that may be
issued under this Plan shall not exceed in the aggregate 500,000 shares of Common Stock. Such
shares may be authorized and unissued shares or authorized and issued shares that have been
reacquired by the Company. If any Options granted under this Plan shall for any reason terminate
or expire or be surrendered without having been exercised in full, then the shares not purchased
under such Options shall be available again for grant hereunder.

ARTICLE IV

STOCK OPTIONS

     4.1 Grant; Terms and Conditions. The Committee, in its discretion, may from time to
time grant Options to any Consultant eligible to receive Options under this Plan. Each Consultant
who is granted an Option shall receive an Option Agreement from the Company in a form specified by
the Committee and containing such provisions, consistent with this Plan, as the Committee, in its
sole discretion, shall determine at the time the Option is granted.

          (a) Number of Shares. Each Option Agreement shall state the number of shares of
Common Stock to which it pertains.

4

 

          (b) Option Price. Each Option Agreement shall state the Option exercise price, which
shall be the price determined by the Committee, in its absolute discretion, to be suitable to
attain the purposes of this Plan; provided that the exercise price of an Option shall not be lower
than the Fair Market Value of the Common Stock as of the date of the grant.

          (c) Medium and Time of Payment. Upon the exercise of an Option, the Option exercise
price shall be payable in United States dollars, in cash (including by check) or (unless the
Committee otherwise prescribes) in shares of Common Stock owned by the optionee, in Options granted
to the optionee under the Plan which are then exercisable, or in a combination of cash, Common
Stock and Options. If all or any portion of the Option exercise price is paid in Common Stock
owned by the optionee, then that Common Stock shall be valued at its Fair Market Value as of the
date the Option is exercised. If all or any portion of the Option exercise price is paid in
Options granted to the optionee under the Plan, then such Options shall be valued at their Fair
Market Value as of the date the Option is exercised. For the purpose of assisting an optionee to
exercise an Option, the Company may, in the discretion of the Board, make loans to the optionee or
guarantee loans made by third parties to the optionee, in either case on such terms and conditions
as the Board may authorize.

          (d) Term and Exercise of Options. The term of each Option shall be determined by the
Committee at the time the Option is granted; provided that the term of an Option shall in no event
be more than ten years from the date of grant. Not less than one hundred shares may be purchased
at any one time unless the number purchased is the total number at the time purchasable under the
Option. During the lifetime of an optionee, the Option shall be exercisable only by him or her and
shall not be assignable or transferable by him or her and no person shall acquire any rights
therein. Following an optionee’s death, the Option may be exercised (to the extent permitted under
the Plan) by the person designated by the optionee as a beneficiary in a written notification
delivered to the Committee prior to the optionee’s death, or if there is no such written
designation, by the executor or administrator of the optionee’s estate or by the person or persons
to whom such rights pass by will or by the laws of descent or distribution.

          (e) Recapitalization; Reorganization. Subject to any required action by the
stockholders of the Company, the maximum number of shares of Common Stock that may be issued under
this Plan, the number of shares of Common Stock covered by each outstanding Option, the kind of
shares subject to outstanding Options and the per share exercise price under each outstanding
Option shall be adjusted, in each case, to the extent and in the manner the Committee deems
appropriate for any increase or decrease in the number of issued shares of Common Stock resulting
from a reorganization, recapitalization, stock split, stock dividend, combination of shares,
merger, consolidation, rights offering, subdivision or consolidation of shares or the payment of a
stock dividend (but only on the Common Stock) or any other change in the corporate structure or
state of the Company.

          Subject to any action that may be required on the part of the stockholders of the Company, if
the Company is the surviving corporation in any merger, consolidation, sale, transfer, acquisition,
tender offer or exchange offer which does not result in a Change of Control,

5

 

then each outstanding Option shall pertain to and apply to the securities or other consideration
that a holder of the number of shares of Common Stock subject to the Option would have been
entitled to receive in such transaction.

          If the Company is the surviving corporation in any merger, consolidation, sale
transfer, acquisition, tender offer or exchange offer which results in a Change of Control, each
optionee shall, in such event, have the right immediately prior to such transaction to exercise his
or her Option in whole or in part without regard to any installment provision contained in his or
her Agreement; provided, however, that the exercisability of any Option shall not be accelerated
if, in the opinion of the Board, such acceleration would prevent pooling of interests accounting
treatment for the Change of Control transaction and such accounting treatment is desired by the
parties to such transaction. Any Option not exercised immediately prior to such transaction shall
pertain to and apply to the securities or other consideration that a holder of the number of shares
of Common Stock subject to the Option would have been entitled to receive in the transaction.

          A merger, consolidation, sale, transfer, acquisition, tender offer or exchange
offer in which the Company is not the surviving corporation, other than such a transaction effected
for the purpose of changing the Company’s domicile, shall cause each holder of an outstanding
Option to have the right immediately prior to such transaction to exercise his or her Option in
whole or in part without regard to any installment provision contained in his or her Agreement.
Any Option not exercised immediately prior to such transaction shall pertain to and apply to the
securities or other consideration that a holder of the number of shares of Common Stock subject to
the Option would have been entitled to receive in the transaction.

          A dissolution or liquidation of the Company shall cause each outstanding Option
to terminate, provided that each holder shall, in such event, have the right immediately prior to
such dissolution or liquidation to exercise his or her Option in whole or in part without regard to
any installment provision contained in his or her Agreement.

          Notwithstanding the foregoing, in no event shall any Option be exercisable after
the date of termination of the exercise period of such Option.

          In the case of a merger, consolidation, sale, transfer, acquisition, tender offer or
exchange offer effected for the purpose of changing the Company’s domicile, each outstanding
Option shall continue in effect in accordance with its terms and shall apply or relate to the same
number of shares of common stock of such surviving corporation as the number of shares of Common
Stock to which it applied or related immediately prior to such transaction, adjusted for any
increase or decrease in the number of outstanding shares of common stock of the surviving
corporation effected without receipt of consideration.

          In the event of a change in the Common Stock as presently constituted, which change is limited
to a change of all of the authorized shares with par value into the same number of shares with a
different par value or without par value, the shares resulting from any such change shall be deemed
to be the Common Stock within the meaning of this Plan.

          The foregoing adjustments shall be made by the Committee, whose determination shall be final,
binding and conclusive.

6

 

          Except as expressly provided in this subsection, the holder of an Option shall have no rights
by reason of (i) any subdivision or consolidation of shares of any class, (ii) any stock dividend,
(iii) any other increase or decrease in the number of shares of stock of any class, (iv) any
dissolution, liquidation, merger or consolidation or spin-off, split-off or split-up of assets of
the Company or stock of another corporation or (v) any issuance by the Company of shares of stock
of any class or securities convertible into shares of stock of any class. Moreover, except as
expressly provided in this subsection, the occurrence of one or more of such events shall not
affect, and no adjustment by reason thereof shall be made with respect to, the number or price of
shares of Common Stock subject to the Option.

          The grant of an Option pursuant to this Plan shall not affect in any way the right or power of
the Company to make adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge or to consolidate or to dissolve, liquidate, sell or otherwise
transfer all or any part of its business or assets.

          (f) Rights as a Stockholder. Subject to Section 5.9 of this Plan regarding
uncertificated shares, an optionee or a transferee of an Option shall have no rights as a
stockholder with respect to any shares covered by his or her Option until the date of the issuance
of a stock certificate to him or her for those shares upon payment of the exercise price. No
adjustments shall be made for dividends (ordinary or extraordinary, whether in cash, securities or
other property) or distributions or other rights for which the record date is prior to the date
such stock certificate is issued, except as provided in subsection 4.1(e).

          (g) Modification, Extension and Renewal of Options. Subject to the terms and
conditions and within the limitations of this Plan, the Committee may, on or after the date of
grant, modify, extend or renew outstanding Options granted under this Plan or accept the surrender
of outstanding Options (to the extent not theretofore exercised) and authorize the granting of new
Options in substitution therefor (to the extent not theretofore exercised). No modification of an
Option shall, without the consent of the holder thereof, alter or impair any rights or obligations
under any Option theretofore granted under this Plan.

          (h) Exercisability and Term of Options. Unless earlier terminated, Options granted
pursuant to this Plan shall be exercisable at any time on or after the dates of exercisability and
before the expiration date set forth in the Option Agreement. Notwithstanding the foregoing,
unless otherwise determined by the Committee on or after the date of grant, an Option shall
terminate and may not be exercised after the date of a Termination of Engagement, except that: (1)
unless the Committee shall determine that the Consultant’s engagement was terminated for conduct
that in the judgment of the Committee involves dishonesty or action by the Consultant that is
detrimental to the best interest of the Company, the Consultant may at any time within three months
after Termination of Engagement exercise his or her Option but only to the extent the Option was
exercisable on the date of Termination of Engagement; (2) if such Consultant’s engagement
terminates on account of total and permanent disability, then the Consultant may at any time within
one year after Termination of Engagement exercise the Option
but only to the extent that the Option was exercisable on the date of Termination of Engagement;
and (3) if such Consultant dies while engaged as a consultant to the Company, or

7

 

within the three
or twelve month period following Termination of Engagement as described in clause (1) or (2) above,
then his or her Option may be exercised at any time within twelve months following his or her death
by the person specified in Section 4.1(d), but only to the extent that such Option was exercisable
by him or her on the date of Termination of Engagement. The Committee may, in its discretion,
provide in any Option Agreement or determine at any time after the date of grant that the
exercisability of an Option will be accelerated, in whole or in part, in the event of a
Consultant’s death or disability. The Committee may, in its discretion, extend the
post-termination exercise periods set forth in this subsection, but not beyond the expiration date
of the Option. Notwithstanding anything to the contrary in this subsection, an Option may not be
exercised by anyone after the expiration of its term.

     4.2 Other Terms and Conditions. Through the Option Agreements authorized under this
Plan, the Committee may impose such other terms and conditions, not inconsistent with the terms
hereof, on the grant or exercise of Options, as it deems advisable.

     4.3 Inclusion of Prior Grants. From and after the Effective Date of this Plan, the
grants of rights to purchase shares of Common Stock listed below shall, for the purposes of this
Plan, be deemed to be Options granted under the terms of, and in accordance with, this Plan, such
Options shall be governed by the terms of this Plan, and the terms of such Options shall include
the terms and provisions of this Plan, the terms and conditions theretofore adopted by the
Committee in connection with the grant of such Options and the terms and conditions set forth in

ARTICLE V

MISCELLANEOUS

     5.1 Withholding Taxes. A Consultant granted Options under this Plan shall be
conclusively deemed to have authorized the Company to withhold from the commissions, fees or other
compensation of such Consultant funds in amounts or property (including Common Stock or Options) in
value equal to any federal, state and local income, employment or other withholding taxes
applicable to the income recognized by such Consultant and attributable to the Options or Option
Shares as, when and to the extent, if any, required by law; provided, however,
that, in lieu of the withholding of federal, state and local taxes as herein provided, the Company
may require that the Consultant (or other person exercising such Option) pay the Company an

8

 

amount
equal to the federal, state and local withholding taxes on such income at the time such withholding
is required or such other time as shall be satisfactory to the Company.

     5.2 Amendment, Suspension, Discontinuance or Termination of Plan. The Board or
Committee may at any time amend, discontinue or terminate the Plan or any part thereof (including
any amendment deemed necessary to ensure that the Company may comply with any regulatory
requirement or any change in applicable law) or for any other purpose permitted by law, or amend
any Option previously granted, prospectively or retroactively (subject to Article III); provided,
however, that, (i) unless otherwise required by law, the rights of a Consultant with respect to
Options granted prior to such amendment, discontinuance or termination may not be impaired without
the consent of such Consultant; (ii) except as otherwise provided in Section 4.1(d) hereof, the
Committee or the Board shall not reduce the exercise price of Options previously awarded to any
Consultant, whether through amendment, cancellation and replacement grant, or any other means,
without prior stockholder approval; and (iii) the Company will seek the approval of the Company’s
stockholders for any amendment if such approval is necessary to comply with the Code, Federal or
state securities laws or any other applicable laws or regulations, including the Marketplace Rules
of the National Association of Securities Dealers, Inc. Unless sooner terminated by the Committee,
this Plan will terminate on September 9, 2007.

     5.3 Governing Law. This Plan shall be governed by, and construed in accordance with,
the laws of the State of Maryland (without giving effect to principles of conflict of laws).

     5.4 Designation. This Plan may be referred to in other documents and instruments as
the “Digene Corporation 1997 Stock Option Plan.”

     5.5 Indemnification of Committee. In addition to such other rights of indemnification
as they may have as directors or as members of the Committee, the members of the Committee shall be
indemnified by the Company against the reasonable expenses, including attorneys’ fees, actually and
necessarily incurred in connection with the defense of any investigation, action, suit or
proceeding, or in connection with any appeal therefrom, to which they or any of them may be a party
by reason of any action taken or failure to act under or in connection with this Plan or any
Option, and against all amounts paid by them in settlement thereof (provided such settlement is
approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a
judgment in or dismissal or other discontinuance of any such investigation, action, suit or
proceeding, except in relation to matters as to which it shall be adjudged in such investigation,
action, suit or proceeding that such Committee member is liable for negligence or misconduct in the
performance of his or her duties; provided that, within 60 days after institution of any such
investigation, action, suit or proceeding, a Committee member shall in writing offer the Company
the opportunity, at its own expense, to handle and defend the same.

     5.6 Reservation of Shares. The Company shall at all times during the term of this
Plan, and so long as any Option shall be outstanding, reserve and keep available (and will seek or
obtain from any regulatory body having jurisdiction any requisite authority in order to issue) such
number of shares of its Common Stock as shall be sufficient to satisfy the requirements of

9

 

this
Plan. Inability of the Company to obtain from any regulatory body of appropriate jurisdiction
authority considered by the Company to be necessary or desirable to the lawful issuance of any
shares of its Common Stock hereunder shall relieve the Company of any liability in respect of the
nonissuance or sale of such Common Stock as to which such requisite authority shall not have been
obtained.

     5.7 Application of Funds. The proceeds received by the Company from the sale of
Common Stock pursuant to the exercise of Options will be used for general corporate purposes.

     5.8 No Obligation to Exercise. The granting of an Option shall impose no obligation
upon the holder to exercise or otherwise realize the value of that Option.

     5.9 Uncertificated Shares. A Consultant who exercises an Option to acquire Common
Stock may, but need not, be issued a stock certificate in respect of the Common Stock so acquired.
A “book entry” (i.e., a computerized or manual entry) shall be made in the records of the
Company to evidence the issuance of shares of Common Stock to a Consultant where no certificate is
issued in the name of the Consultant. Such Company records, absent manifest error, shall be
binding on Consultants. In all instances where the date of issuance of shares may be deemed
significant but no certificate is issued in accordance with this Section 5.9, the date of the book
entry shall be the relevant date for such purposes.

     5.10 Forfeiture for Competition. If a participant in this Plan provides services to a
competitor of the Company or any of its subsidiaries, whether as an employee, officer, director,
independent contractor, consultant, agent or otherwise, such services being of a nature that can
reasonably be expected to involve the skills and experience used or developed by the participant
while a Consultant, then that participant’s rights to any Options hereunder shall automatically be
forfeited, subject to a determination to the contrary by the Committee.

     5.11 Successors. This Plan shall be binding upon any and all successors of the
Company.

     5.12 Engagement Rights. Nothing in this Plan or in any Option Agreement shall confer
on any Consultant any right to continue as a Consultant of the Company or any of its subsidiaries
or shall interfere in any way with the right of the Company or any of its subsidiaries to terminate
such person’s engagement at any time.

     5.13 Other Actions. Nothing contained in the Plan shall be construed to limit the
authority of the Company to exercise its corporate rights and powers, including, but not by way of
limitation, the right of the Company to grant options for proper corporate purposes other than
under the Plan with respect to any employee or other person, firm, corporation or association.

     5.14 Tax Treatment and Characterization. The Options granted hereunder shall not be
considered incentive stock options that qualify under Code Section 422.

     5.15 Legend. The Committee may require each person exercising an Option to represent
to and agree with the Company in writing that he or she is acquiring the Option Shares

10

 

without a
view to distribution thereof. In addition to any legend required by this Plan, the stock
certificates representing such Option Shares may include any legend which the Committee deems
appropriate to reflect any restrictions on transfer.

          All certificates for Option Shares shall be subject to such stock transfer orders and other
restrictions as the Committee may deem advisable under the rules, regulations and other
requirements of the Securities and Exchange Commission, any stock exchange upon which the Common
Stock is then listed, any applicable federal or state securities law, and any applicable corporate
law, and the Committee may cause a legend or legends to be put on any such certificates to make
appropriate reference to such restrictions.

     5.16 Unfunded Status of Plan. The Plan is intended to constitute an “unfunded plan
for incentive compensation. With respect to any payment not yet made to a participant in this Plan
by the Company, nothing contained herein shall give any such participant any rights that are
greater than those of a general creditor of the Company.

     5.17 Listing and Other Conditions.

          (a) If the Common Stock is listed on a national securities exchange, the issuance of any
shares of Common Stock upon exercise of an Option shall be conditioned upon such shares being
listed on such exchange. The Company shall have no obligation to issue such shares unless and
until such shares are so listed, and the right to exercise any Option shall be suspended until such
listing has been effected.

          (b) If at any time counsel to the Company shall be of the opinion that any sale or delivery of
shares of Common Stock upon exercise of an Option is or may in the circumstances be unlawful or
result in the imposition of excise taxes under the statutes, rules or regulations of any applicable
jurisdiction, the Company shall have no obligation to make such sale or delivery, or to make any
application or to effect or to maintain any qualification or registration under the Securities Act
of 1933, as amended, or otherwise with respect to shares of Common Stock, and the right to exercise
any Option shall be suspended until, in the opinion of such counsel, such sale or delivery shall be
lawful or shall not result in the imposition of excise taxes.

          (c) Upon termination of any period of suspension under this Section 5.17, any Option affected
by such suspension which shall not then have expired or terminated shall be reinstated as to all
shares available before such suspension and as to shares which would otherwise have become

     5.19 Severability. If any part of the Plan shall be determined to be invalid or void
in any respect, such determination shall not affect, impair, invalidate or nullify the remaining
provisions of the Plan which shall continue in full force and effect.

     3.2 Awards. The Committee shall have full authority to grant, pursuant to the terms
of the Plan, Stock Options, Restricted Stock Units, Unrestricted Stock or Performance Shares to
persons eligible under Article V. In particular, the Committee shall have the authority:

          (a) to select the persons to whom Stock Options, Restricted Stock Units, Unrestricted Stock or
Performance Shares may from time to time be granted;

          (b) to determine whether and to what extent Incentive Stock Options, Non-Qualified Stock
Options, Restricted Stock Units, Unrestricted Stock or Performance Shares, or any combination
thereof, are to be granted to one or more persons eligible to receive Awards under Article V;

          (c) to determine the number of shares of Common Stock to be covered by each Award granted
hereunder; and

          (d) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any
Award granted hereunder (including, but not limited to, the option price, the option term, and
provisions relating to any restriction or limitation, any vesting schedule or acceleration, any
performance guidelines or criteria or any forfeiture restrictions or waiver provisions of the
Award), and any conditions (in addition to those contained in this Plan) on the exercisability of
all or any part of an Option or on the transferability or forfeitability of Restricted Stock Units.
Notwithstanding any such conditions, the Committee may, in its discretion at any time, accelerate
the time at which any Option may be exercised or the time at which the Common Stock underlying
Restricted Stock Units may become transferable or nonforfeitable.

     3.3 Guidelines. Subject to Article IX hereof, the Committee shall have the authority
to adopt, alter and repeal such administrative rules, guidelines and practices governing the Plan
as it shall, from time to time, deem advisable; to interpret the terms and provisions of the Plan
and any Award granted under the Plan (and any agreements relating thereto); and to otherwise

4

 

supervise the administration of the Plan. The express grant in the Plan of any specific power to
the Committee shall not be construed as limiting any other power or authority of the Committee.
The Committee may correct any defect, supply any omission or reconcile any inconsistency in the
Plan or in any Award in the manner and to the extent it shall deem necessary or advisable to carry
out the purposes of the Plan. Notwithstanding the foregoing, no action of the Committee under this
Section 3.3 shall impair the rights of any Participant without the Participant’s consent, unless
otherwise required by law.

     A majority of the entire Committee shall constitute a quorum, and the action of a majority of
the members present at any meeting at which a quorum is present shall be deemed the action of the
Committee. In addition, any decision or determination reduced to writing and signed by all of the
members of the Committee shall be fully as effective as if it had been made by a majority vote at a
meeting duly called and held. Subject to the provisions of this Plan and the Company’s Bylaws, and
to any terms and conditions prescribed by the Board, the Committee may make such additional rules
and regulations for the conduct of its business as it shall deem advisable. The Committee shall
hold meetings at such times and places as it may determine.

     3.4 Decisions Final. Any decision, interpretation or other action made or taken in
good faith by the Committee arising out of or in connection with the Plan shall be final, binding
and conclusive on the Company, all Participants and their respective heirs, executors,
administrators, successors and assigns.

Article IV

Share Limitation

     4.1 Shares. The maximum aggregate number of shares of Common Stock that may be issued
under the Plan is 5,100,000 (subject to increase or decrease pursuant to Section 4.3), which may be
either authorized and unissued shares of Common Stock or authorized and issued shares of Common
Stock reacquired by the Company; provided that any grant of Performance Shares, Restricted Stock
Units or Unrestricted Stock under the Plan on or after October 26, 2005 will be counted against the
maximum aggregate number of shares issuable under the Plan as two shares of Common Stock for every
one share of Common Stock subject thereto. If any Option granted under the Plan shall expire,
terminate or be canceled for any reason without having been exercised in full, the number of shares
of Common Stock not purchased under such Option shall again be available for the purposes of the
Plan. Further, if any Performance Shares are unearned or forfeited, or Restricted Stock Units are
forfeited, the shares subject to the portion of such Award unearned or forfeited, as the case may
be, shall again be available under the Plan; provided that, to the extent that a share of Common
Stock that was subject to an Award that counted as two shares against the maximum aggregate number
of shares issuable under the Plan is recycled back into the Plan, the Plan will be credited with
two shares. Notwithstanding anything to the contrary in this Section 4.1, (i) should the exercise
price of a Stock Option be paid with shares of Common Stock or by reducing the number of shares of
Common Stock issuable upon such exercise, or (ii) should shares of Common Stock otherwise issuable
under the
Plan be paid in cash or withheld by the Company in satisfaction of the withholding taxes
incurred in connection with the exercise of a Stock Option or the vesting of an Award, then the
number of shares of Common Stock available for issuance under the Plan shall be reduced by the
gross number of shares for which the Stock Option is exercised or which vest under the Award,

5

 

and
not by the net number of shares of Common Stock issued to the holder of such Stock Option or Award.

     4.2 Individual Limit. No Employee may be granted Awards covering more than 500,000
shares of Common Stock (subject to increase or decrease pursuant to Section 4.3) during any
calendar year.

     4.3 Changes. In the event of any merger, reorganization, consolidation,
recapitalization, dividend (other than a regular cash dividend), stock split, or other change in
corporate structure affecting the Common Stock, such substitution or adjustment shall be made in
the maximum aggregate number of shares which may be issued under the Plan, the maximum number of
shares with respect to which Awards may be granted to any individual during any year, the number
and option price of shares subject to outstanding Options, and the number of shares subject to
other outstanding Awards, as may be determined to be appropriate by the Committee, in its sole
discretion, provided that the number of shares subject to any Award shall always be a whole number.

Article V

Eligibility

     5.1 Awards to Employees. All officers and other Employees of the Company and its
Subsidiaries are eligible to be granted Incentive Stock Options, Non-Qualified Stock Options,
Restricted Stock Units, Unrestricted Stock or Performance Shares under the Plan. A Director who is
an Employee of the Company or a Subsidiary shall be eligible to receive Awards pursuant to this
Article V.

Article VI

Stock Options

     6.1 Options. Each Stock Option granted under the Plan shall be either an Incentive
Stock Option or a Non-Qualified Stock Option.

     6.2 Grants. The Committee shall have the authority to grant to any person eligible
under Section 5.1 one or more Incentive Stock Options, Non-Qualified Stock Options, or both types
of Stock Options. To the extent that any Stock Option does not qualify as an Incentive Stock
Option (whether because of its provisions or the time or manner of its exercise or otherwise), such
Stock Option or the portion thereof which does not qualify as an Incentive Stock Option shall
constitute a separate Non-Qualified Stock Option.

     6.3 Incentive Stock Options. Anything in the Plan to the contrary notwithstanding, no
term of the Plan relating to Incentive Stock Options shall be interpreted, amended or altered, nor
shall any discretion or authority granted under the Plan be exercised, so as to disqualify the Plan
under Section 422 of the Code, or, without the consent of the Participants affected, to
disqualify any Incentive Stock Option under such Section 422 of the Code.

6

 

     6.4 Terms of Options. Options granted under the Plan shall be subject to the
following terms and conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of the Plan, as the Committee shall deem desirable:

          (a) Stock Option Certificate. Each Stock Option shall be evidenced by, and subject to
the terms of, a Stock Option Certificate evidencing the Stock Option grant. The Stock Option
Certificate shall specify whether the Option is an Incentive Stock Option or a Non-Qualified Stock
Option, the number of shares of Common Stock subject to the Stock Option, the option price, the
option term, and the other terms and conditions applicable to the Stock Option.

          (b) Option Price. Subject to subsection (m) below, the option price per share of
Common Stock purchasable upon exercise of a Stock Option shall be determined by the Committee at
the time of grant, but shall be not less than 100% of the Fair Market Value of the Common Stock on
the Date of Grant.

          (c) Option Term. Subject to subsection (m) below, the term of each Stock Option shall
be fixed by the Committee at the time of grant, but no Stock Option granted prior to September 20,
2005 shall be exercisable more than ten years after the date it is granted and no Stock Option
granted on or after September 20, 2005 shall be exercisable more than seven years after the date it
is granted.

          (d) Exercisability. Stock Options shall be exercisable at such time or times and
subject to such terms and conditions as shall be determined by the Committee at the time of grant;
provided, however, that the Committee may waive any installment exercise or waiting period
provisions, in whole or in part, at any time after the Date of Grant, based on such factors as the
Committee shall deem appropriate in its sole discretion.

          (e) Method of Exercise. Subject to such installment exercise and waiting period
provisions as may be imposed by the Committee, Stock Options may be exercised in whole or in part
at any time during the option term by delivering to the Company written notice of exercise
specifying the number of shares of Common Stock to be purchased and the option price therefor. The
notice of exercise shall be accompanied by payment in full of the option price and, if requested,
by the representation described in Section 11.2. Payment of the option price may be made (i) in
cash or by check payable to the Company, (ii) unless otherwise determined by the Committee on or
after the Date of Grant, in shares of Common Stock duly owned by the Participant (and for which the
Participant has good title free and clear of any liens and encumbrances) or (iii) in the case of an
Option that is not an Incentive Stock Option, unless otherwise determined by the Committee on or
after the Date of Grant, by reduction in the number of shares of Common Stock issuable upon such
exercise, based, in each case, on the Fair Market Value of the Common Stock on the date of
exercise. Upon satisfaction of the conditions provided herein, a stock certificate representing
the number of shares of Common Stock to which the Participant is entitled shall be issued and
delivered to the Participant, subject to Section 11.3. For the purpose of assisting a Participant
to exercise an Option, the Company may, in the discretion of the Board, make loans to the
Participant or guarantee loans made by third parties to the Participant, in either case on such
terms and conditions as the Board may authorize. Nothing
contained in this Plan shall prevent or prohibit a Participant from exercising his or her
Options under a broker-facilitated cashless exercise transaction.

7

 

          (f) Death. Unless otherwise determined by the Committee on or after the Date of
Grant, in the event of a Participant’s Termination of Employment by reason of death, any Stock
Option held by such Participant which was exercisable on the date of death may thereafter be
exercised by the legal representative of the Participant’s estate until the earlier of one year
after the date of death or the expiration of the stated term of such Stock Option, and any Stock
Option not exercisable on the date of death shall be forfeited.

          (g) Disability. Unless otherwise determined by the Committee on or after the Date of
Grant, in the event of a Participant’s Termination of Employment by reason of Disability, any Stock
Option held by such Participant which was exercisable on the date of such Termination of Employment
may thereafter be exercised by the Participant until the earlier of one year after such date or the
expiration of the stated term of such Stock Option, and any Stock Option not exercisable on the
date of such Termination of Employment shall be forfeited. If the Participant dies during such
one-year period, any unexercised Stock Options held by the Participant at the time of death may
thereafter be exercised by the legal representative of the Participant’s estate until the earlier
of one year after the date of the Participant’s death or the expiration of the stated term of such
Stock Option. If an Incentive Stock Option is exercised after the expiration of the exercise
period that applies for purposes of Section 422 of the Code, such Stock Option will thereafter be
treated as a Non-Qualified Stock Option.

          (h) Termination of Employment. Subject to Section 11.4, in the event of a
Participant’s Termination of Employment by reason of retirement or for any reason other than death
or Disability, all Stock Options held by such Participant that were exercisable on the date of such
Termination of Employment may be exercised by the Participant at any time during the longer of: (i)
the three (3) month period after his or her Termination of Employment; or (ii) in the case of an
Option that is not an Incentive Stock Option and in the sole discretion of the Committee and as
long as such change does not have an adverse affect under Section 409A of the Code, if, at the time
of the Participant’s Termination of Employment, the Participant is engaged as a consultant by the
Company, the period during which the Participant is engaged as a consultant by the Company but not
to exceed twelve (12) months after the Participant’s Termination of Employment; provided, however,
that if the Committee shall determine that the Employee’s employment was terminated for conduct
that in the judgment of the Committee involves dishonesty or action by the Employee that is
detrimental to the best interest of the Company, all Stock Options held by the Employee on the date
of such Termination of Employment shall be forfeited. Notwithstanding anything to the contrary in
this Subsection, but subject to the last sentence of this Subsection, a Stock Option shall not
terminate upon a Participant’s Termination of Employment if at the time thereof the Participant
serves as a Director of the Company or its successor. In such event, once the Participant ceases
to be a Director of the Company or its successor, all Stock Options held by such Participant that
were exercisable on the date the Participant ceased to be a Director may be exercised by the
Participant at any time during the three month period after the Participant ceases to be a
Director. Notwithstanding anything to the contrary in this Subsection, no Stock Option may be
exercised after the expiration of the stated term of such Stock Option.

          (i) Change of Control. Notwithstanding the provisions of Section 4.3, in the event of
a Change of Control, all outstanding Stock Options shall immediately become fully exercisable, and
upon payment by the Participant of the option price (and, if requested, delivery of the
representation described in Section 11.2), a stock certificate representing the Common

8

 

Stock
covered thereby shall be issued and delivered to the Participant. This Section 6.4(i) shall apply
to any outstanding Stock Options which are Incentive Stock Options to the extent permitted by Code
Section 422(d), and any outstanding Incentive Stock Options in excess thereof shall, immediately
upon the occurrence of such a Change of Control be treated for all purposes of the Plan as
Non-Qualified Stock Options and shall be immediately exercisable as set forth in this Section
6.4(i).

          (j) Merger and Other Fundamental Transactions. In the event the Company is succeeded
by another company in a reorganization, merger, consolidation, acquisition of property or stock,
separation or liquidation, the successor company shall assume all of the outstanding Options
granted under this Plan or shall substitute new options for them, which shall provide that each
Participant, at the same cost, shall be entitled upon the exercise of each such option to receive
such securities as the Board of Directors (or equivalent governing body) of the succeeding,
resulting or other company shall determine to be equivalent, as nearly as practicable, to the
nearest whole number and class of shares of stock or other securities to which the Participant
would have been entitled under the terms of the agreement governing the reorganization, merger,
consolidation, acquisition of property or stock, separation or liquidation as if, immediately prior
to such event, the Participant had been the holder of record of the number of shares of Common
Stock which were then subject to the outstanding Option granted under this Plan.

          (k) Non-Transferability of Options. No Stock Option shall be transferable by the
Participant otherwise than by will or by the laws of descent and distribution, to the extent
consistent with the terms of the Plan and the Option, and all Stock Options shall be exercisable,
during the Participant’s lifetime, only by the Participant.

          (l) Incentive Stock Option Limitations. To the extent that the aggregate Fair Market
Value (determined as of the Date of Grant) of the Common Stock with respect to which Incentive
Stock Options are exercisable for the first time by the Participant during any calendar year under
the Plan and/or any other stock option plan of the Company or any subsidiary or parent corporation
(each within the meaning of Section 424 of the Code) exceeds $100,000, such Options shall be
treated as Options which are not Incentive Stock Options.

          (m) Ten-Percent Stockholder Rule. Notwithstanding any other provision of the Plan to
the contrary, no Incentive Stock Option shall be granted to any person who, immediately prior to
the grant, owns stock possessing more than ten percent of the total combined voting power of all
classes of stock of the Company or any subsidiary or parent corporation (each within the meaning of
Section 424 of the Code), unless the option price is at least 110% of the Fair Market Value of the
Common Stock on the Date of Grant and the Option, by its terms, expires no later than five years
after the Date of Grant.

     Should the foregoing provisions not be necessary in order for the Stock Options to qualify as
Incentive Stock Options, or should any additional provisions be required, the
Committee may amend the Plan accordingly, without the necessity of obtaining the approval of
the stockholders of the Company.

     6.5 Rights as Stockholder. A Participant shall not be deemed to be the holder of
Common Stock, or to have any of the rights of a holder of Common Stock, with respect to shares

9

 

subject to the Option, unless and until the Option is exercised and a stock certificate
representing such shares of Common Stock is issued to the Participant.

Article VII

Performance Shares

     7.1 Award of Performance Shares. The Committee shall have the authority to award
Performance Shares to any person eligible under Section 5.1. The Committee shall determine the
eligible Employees to whom, and the time or times at which, Performance Shares shall be awarded,
the number of Performance Shares to be awarded to any Employee, the duration of the Performance
Period with respect to each Performance Shares Award, the medium of payment upon vesting and the
other terms and conditions of the Performance Shares Award, including those set forth in Section
7.2.

     7.2 Terms and Conditions. Performance Shares awarded pursuant to this Article VII
shall be subject to the following terms and conditions and such other terms and conditions, not
inconsistent with the terms of this Plan, as the Committee shall deem desirable:

          (a) Performance Period. At the time of a Performance Shares Award, the Committee, in
its sole discretion, shall establish a Performance Period of not less than (1) year nor more than
five (5) years, commencing on the Date of Grant of the Performance Shares Award.

          (b) Performance Goals. A Performance Shares Award will vest and be earned based on
the attainment of one or more identified Performance Goals determined by the Committee. The
Performance Goals (although their measurement, including adjustments, if any, as permitted under
Subsection 7.2(c), will not occur until after the expiration of the applicable Performance Period)
must be met during the continuance of the Participant’s employment with the Company or any
Subsidiary, prior to the expiration of the applicable Performance Period. Performance Goals may
vary among Participants and among Performance Shares Awards to a Participant.

          (c) Revisions for Significant Events. When circumstances occur (including, but not
limited to, unusual or nonrecurring events, changes in tax laws or accounting principles or
practices) that cause any Performance Goal to be inappropriate in the judgment of the Committee,
the Committee may make such changes as it deems equitable in recognition of any unforeseen events
or changes in circumstances or changed business or economic conditions, as long as any such changes
are consistent with Section 162(m) of the Code.

          (d) Performance Shares Award Commitment. Each Performance Shares Award shall be
evidenced by, and subject to the terms of, a Performance Shares Award Commitment. The Performance
Shares Award Commitment shall specify the number of shares of Common Stock subject to the
Performance Shares Award, the medium of payment, the
applicable Performance Period and the other terms and conditions applicable to such
Performance Shares Award.

          (e) Changes. If any change is made in the Common Stock by reason of any merger,
consolidation, reorganization, recapitalization, stock dividend, split up, combination of

shares, exchange of shares, change in corporate structure, or otherwise, the Committee shall
be entitled to determine the impact of such event on outstanding Performance Shares Awards, and to
make adjustments to each Performance Shares Award to the extent necessary to provide that the
Participant receive, to the extent possible, equivalent rights under such Performance Shares Award
after consummation of such event.

          (f) Achievement of Performance Goals. Within a period of time determined by the
Committee, but not to exceed 90 days after the end of a Performance Period, the Committee will
determine if the applicable Performance Goals were met with respect to applicable Performance
Shares Awards. If the Committee certifies in writing, after the expiration of the Performance
Period, that the Performance Goals specified in a Performance Shares Award Commitment and all other
material terms of the Award have been satisfied, the Performance Shares Award shall be vested and
earned in accordance with such Committee certification.

          (g) Payment of Performance Shares Awards. Payment of a vested, earned Performance
Shares Award shall be made either in shares of Common Stock, or in cash, or in some combination
thereof, as determined by the Committee. The medium of payment shall be set forth in the
Committee’s resolution granting the Performance Shares Award and in the Performance Shares Award
Commitment with the Participant. For an earned Performance Shares Award, or portion thereof, to be
settled through the issuance of shares of Common Stock, the number of shares delivered shall be
equal to the number of applicable Performance Shares earned. The holder may elect to reduce this
amount by the number of shares of Common Stock which have, on the date the Performance Shares Award
is settled, a Fair Market Value equal to the applicable federal, state and local withholding tax
due on the receipt of the Common Stock, in lieu of making a cash payment equal to the amount of
such withholding tax due. For an earned Performance Shares Award, or portion thereof, to be
settled in cash, the amount of cash paid shall be equal to the number of applicable Performance
Shares earned multiplied by the Fair Market Value of a share of Common Stock on such date following
the lapse of the Performance Period and the satisfaction of any other applicable conditions
established by the Committee at the time of grant, that the Participant first becomes entitled to
receive such payment. Such amount will be reduced by applicable federal, state and local
withholding tax due. For any earned Performance Shares Award paid in cash, the shares of Common
Stock designated in the Performance Shares Award shall be deemed to have been issued for purposes
of Section 4.1 hereof.

          (h) Non-Transferability of Performance Shares Awards. No Performance Shares Awards
shall be transferable by the Participant prior to the determination that such Performance Shares
Award is vested and earned, otherwise than by will or by the laws of descent and distribution, to
the extent consistent with the terms of the Plan.

     7.3 Death or Disability. Subject to the provisions of this Plan and the Performance
Shares Award Commitment, in the event of the death or Disability of a Participant, the Participant
or the Participant’s estate, as the case may be, shall be entitled to receive, at the expiration of
the Performance Period, a percentage of Performance Shares that is equal to the percentage of the
Performance Period that had elapsed as of the date of death or date on which such Disability
commenced (as determined by the Committee in its sole discretion); provided that the Committee, in
its sole discretion, determines that the conditions specified in the

11

 

Performance Shares Awards Commitment have been satisfied. Payment of such portion of the
Performance Shares Award shall be made to the Participant or the Participant’s estate, as the case
may be, in accordance with this Article VII.

     7.4 Change of Control. At the time a Performance Shares Award is made by the
Committee, the Committee shall be entitled, notwithstanding the provisions of Section 4.3, to
provide for different terms and provisions in the event of a Change in Control, including, but not
limited to, the authority to provide for the settlement of a Performance Shares Award, regardless
of whether the applicable Performance Period has expired or whether the applicable Performance
Goals have been met.

     7.5 Termination of Employment. Subject to Sections 7.4 and 11.4, in the event of a
Participant’s Termination of Employment by reason of retirement or for any reason other than death
or Disability, all Performance Shares Awards held by such Participant that were earned on the date
of such Termination of Employment will be paid to the Participant; provided, however, that if the
Committee shall determine that the Employee’s employment was terminated for conduct that in the
judgment of the Committee involves dishonesty or action by the Employee that is detrimental to the
best interest of the Company, all earned but unpaid Performance Shares held by the Employee on the
date of such Termination of Employment shall be forfeited. Notwithstanding anything to the
contrary in this Subsection, a Performance Shares Award shall not terminate upon a Participant’s
Termination of Employment if at the time thereof the Participant serves as a Director of the
Company or its successor, in which event the Performance Shares Awards shall terminate if the
Participant ceases to be a Director of the Company or its successor, and any earned Performance
Shares Award will be then paid in accordance with this Subsection.

Article VIII

Restricted Stock Units and Unrestricted Stock

     8.1 Awards of Restricted Stock Units. The Committee shall have the authority to grant
to any person eligible under Section 5.1 one or more Restricted Stock Unit Awards. The Committee
shall determine the eligible Employees to whom, and the time or times at which, grants of
Restricted Stock Units will be made, the number of shares to be awarded, the time or times within
which such Awards may be subject to forfeiture, the vesting schedule and rights to acceleration
thereof, and the other terms and conditions of the Awards in addition to those set forth in Section
8.2.

     8.2 Terms and Conditions. Restricted Stock Units shall be subject to the following
terms and conditions and such other terms and conditions, not inconsistent with the terms of the
Plan, as the Committee shall deem desirable:

          (a) Restricted Stock Unit Agreement. Each Restricted Stock Unit Award shall be
evidenced by, and subject to the terms of, a Restricted Stock Unit Agreement executed by the
Company and the Participant. The Restricted Stock Unit Agreement shall specify the number of
shares of Common Stock subject to the Award, the time or times within which such Award is subject
to forfeiture and the other terms, conditions and restrictions applicable to such Award.

12

 

          (b) Stock Certificate. Subject to Section 11.3, when the restrictions applicable to a
Restricted Stock Unit Award, or any portion thereof, lapse, a stock certificate representing the
number of shares of Common Stock covered by such Restricted Stock Unit Award, or portion thereof,
shall be issued and delivered to the Participant. A Participant shall not be deemed to be the
holder of Common Stock, or to have any of the rights of a holder of Common Stock, with respect to
shares underlying any Restricted Stock Unit Award, unless and until the forfeiture restrictions
lapse and a stock certificate representing such shares of Common Stock is issued to the
Participant.

          (c) Restriction Period. Subject to the provisions of the Plan and the Restricted
Stock Unit Agreement, Restricted Stock Units will be forfeited to the Company in the event of a
Participant’s Termination of Employment during a period (not to exceed five years) set by the
Committee commencing with the date of such Award (the “Restriction Period”). Subject to the
provisions of the Plan, the Committee, in its sole discretion, may provide for the lapse of such
restrictions in installments and may waive such restrictions, in whole or in part, at any time,
based on such factors as the Committee shall deem appropriate in its sole discretion.

          (d) Termination of Employment. Subject to Section 11.4, in the event of a
Participant’s Termination of Employment prior to the expiration of the Restriction Period, then he
or she shall forfeit all of his or her Restricted Stock Units with respect to which the Restriction
Period has not yet expired; provided, however, that the terms of the Restricted Stock Unit
Agreement, in the discretion of the Committee and pursuant to such terms and conditions as it may
impose, may provide: (i) that, if such Employee’s employment is terminated for any reason other
than conduct that in the judgment of the Committee involves dishonesty or action by the Employee
that is detrimental to the best interests of the Company, then the Restricted Stock Units or any
related compensation deferral or a portion thereof shall not be forfeited; (ii) that, if such
Employee’s employment is terminated on account of Disability, then the Employee shall not forfeit
his or her Restricted Stock Units or any related compensation deferral or a portion thereof; and
(iii) that, if such Employee dies while employed by the Company or any of its Subsidiaries, then
his or her Restricted Stock Units or any related compensation deferral or a portion thereof is not
forfeited.

          (e) Changes. If any change is made in the Common Stock by reason of any merger,
consolidation, reorganization, recapitalization, stock dividend, split up, combination of shares,
exchange of shares, change in corporate structure, or otherwise, then any shares or other
securities of the Company or succeeding, resulting or other company to be received by the Employee
under the Restricted Stock Unit Agreement shall be subject to the same restrictions applicable to
the Restricted Stock Units.

          (f) Non-Transferability of Restricted Stock Unit Awards. No Restricted Stock Units
shall be transferable by the Participant prior to vesting and/or lapse of the applicable forfeiture
restrictions otherwise than by will or by the laws of descent and distribution, to the extent
consistent with the terms of the Plan.

     8.3 Unrestricted Stock. The Committee shall have the authority to grant to any person
eligible under Section 5.1 one or more Unrestricted Stock Awards. Each Employee who is awarded
Unrestricted Stock shall receive an Unrestricted Stock Agreement from the Company in a form
specified by the Committee and containing the terms and conditions of the award and

13

 

such other matters, consistent with this Plan, as the Committee, in its sole discretion, shall
determine at the time the Award is made. Such conditions may include, but shall not be limited to,
the deferral of a percentage of the Employee’s annual cash compensation, not including dividends
paid on the Unrestricted Stock, if any, to be applied toward the purchase of Unrestricted Stock
upon such terms and conditions, including such discounts, as may be set forth in the Unrestricted
Stock Agreement. Upon the issuance of Unrestricted Stock to an Employee hereunder, the Employee
shall have the entire beneficial ownership and all the rights and privileges of a stockholder with
respect to the Unrestricted Stock awarded to him or her, including the right to receive dividends
and the right to vote such Unrestricted Stock. Subject to Section 11.3, each Employee who is
awarded Unrestricted Stock may, but need not, be issued a stock certificate in respect of such
shares of Unrestricted Stock.

Article IX

Termination or Amendment

     9.1 Termination or Amendment of Plan. The Committee may at any time amend,
discontinue or terminate the Plan or any part thereof (including any amendment deemed necessary to
ensure that the Company may comply with any regulatory requirement referred to in Article XI) or
amend any Award previously granted, prospectively or retroactively (subject to Article IV);
provided, however, that, (i) unless otherwise required by law, the rights of a Participant with
respect to Awards granted prior to such amendment, discontinuance or termination may not be
impaired without the consent of such Participant; (ii) except as otherwise provided in Section 4.3
hereof, the Committee shall not reduce the exercise price of Stock Options previously awarded to
any Participant, whether through amendment, cancellation and replacement grant, or any other means,
without prior stockholder approval; and (iii) the Company will seek the approval of the Company’s
stockholders for any amendment if such approval is necessary to comply with the Code, Federal or
state securities laws or any other applicable laws or regulations, including the Marketplace Rules
of the National Association of Securities Dealers, Inc.

Article X

Unfunded Plan

     10.1 Unfunded Plan. The Plan is intended to constitute an “unfunded” plan for
incentive compensation. With respect to any payment not yet made to a Participant by the Company,
nothing contained herein shall give any such Participant any rights that are greater than those of
a general creditor of the Company.

Article XI

General Provisions

     11.1 Nonassignment. Except as otherwise provided in the Plan, any Award granted
hereunder and the rights and privileges conferred thereby shall not be sold, transferred, assigned,
pledged or hypothecated in any way (whether by operation of law or otherwise), and shall not be
subject to execution, attachment or similar process. Upon any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of an Award, right or privilege contrary to the provisions

14

 

hereof, or upon the levy of any attachment or similar process thereon, such Award and the
rights and privileges conferred hereby shall immediately terminate and the Award shall immediately
be forfeited to the Company.

     11.2 Legend. The Committee may require each person acquiring shares pursuant to an
Award to represent to the Company in writing that the Participant is acquiring the shares without a
view to distribution thereof. The stock certificates representing such shares may include any
legend which the Committee deems appropriate to reflect any restrictions on transfer.

     All certificates representing shares of Common Stock delivered under the Plan shall be subject
to such stock transfer orders and other restrictions as the Committee may deem advisable under the
rules, regulations and other requirements of the Securities and Exchange Commission, any stock
exchange or stock market upon which the Common Stock is then listed or traded, any applicable
Federal or state securities law, and any applicable corporate law, and the Committee may cause a
legend or legends to be put on any such certificates to make appropriate reference to such
restrictions.

     11.3 Uncertificated Shares. Each Employee who exercises an Option to acquire Common
Stock, is issued Common Stock upon the vesting of a Performance Shares Award or lapse of forfeiture
restrictions under a Restricted Stock Unit Award or is issued Unrestricted Stock may, but need not,
be issued a stock certificate in respect of the Common Stock so acquired. A “book entry”
(i.e., a computerized or manual entry) shall be made in the records of the Company to
evidence the issuance of shares of Common Stock to an Employee where no certificate is issued in
the name of the Employee. Such Company records, absent manifest error, shall be binding on
Employees. In all instances where the date of issuance of shares may be deemed significant but no
certificate is issued in accordance with this Section 11.3, the date of the book entry shall be the
relevant date for such purposes.

     11.4 Forfeiture for Competition. If a Participant in this Plan provides services to a
competitor of the Company or any of its subsidiaries, whether as an employee, officer, director,
independent contractor, consultant, agent or otherwise, such services being of a nature that can
reasonably be expected to involve the skills and experience used or developed by the Participant
while an Employee, and the Committee determines, in its sole discretion, that the provision of such
services constitutes a breach of the Participant’s non-compete agreement with the Company, then
that Participant’s rights to any Awards hereunder shall automatically be forfeited.

     11.5 Other Plans. Nothing contained in the Plan shall prevent the Board from adopting
other or additional compensation arrangements, subject to stockholder approval if such approval is
required; and such arrangements may be either generally applicable or applicable only in specific
cases.

     11.6 No Right to Employment. Neither the Plan nor the grant of any Award hereunder
shall give any Participant or other Employee any right with respect to continuance of employment by
the Company or any Subsidiary, nor shall the Plan impose any limitation on the right of the Company
or any Subsidiary by which a Participant is employed to terminate such Participant’s employment at
any time.

15

 

     11.7 Withholding of Taxes. The Company shall have the right to reduce the number of
shares of Common Stock otherwise deliverable pursuant to an Award under this Plan by an amount that
would have a fair market value equal to the minimum amount of all Federal, state and local taxes
required to be withheld, or to deduct the amount of such taxes from any cash payment otherwise to
be made to the Participant. In connection with such withholding, the Committee may make such
arrangements as are consistent with the Plan as it may deem appropriate.

     11.8 Listing and Other Conditions.

          (a) If the Common Stock is listed on a national securities exchange or The Nasdaq Stock
Market, the issuance of any shares of Common Stock pursuant to an Award shall be conditioned upon
such shares being listed on such exchange or The Nasdaq Stock Market. The Company shall have no
obligation to issue any shares of Common Stock unless and until such shares are so listed, and the
right to exercise any Option or vest in any Restricted Stock Unit shall be suspended until such
listing has been effected.

          (b) If at any time counsel to the Company shall be of the opinion that any sale or delivery of
shares of Common Stock pursuant to an Award is or may in the circumstances be unlawful or result in
the imposition of excise taxes under the statutes, rules or regulations of any applicable
jurisdiction, the Company shall have no obligation to make such sale or delivery, or to make any
application or to effect or to maintain any qualification or registration under the Securities Act
of 1933, as amended, or otherwise with respect to shares of Common Stock or Awards, and the right
to exercise any Option or vest in any Restricted Stock Unit shall be suspended until, in the
opinion of such counsel, such sale or delivery shall be lawful or shall not result in the
imposition of excise taxes.

          (c) Upon termination of any period of suspension under this Section 11.8, any Award affected
by such suspension which shall not then have expired or terminated shall be reinstated as to all
shares available before such suspension and as to shares which would otherwise have become
available during the period of such suspension, but no such suspension shall extend the term of any
Option.

     11.9 Governing Law. The Plan and actions taken in connection herewith shall be
governed and construed in accordance with the laws of the State of Delaware, without regard to the
conflict of laws principles thereof.

     11.10 Construction. Wherever any words are used in the Plan in the masculine gender
they shall be construed as though they were also used in the feminine gender in all cases where
they would so apply, and wherever any words are used herein in the singular form they shall be
construed as though they were also used in the plural form in all cases where they would so apply.

     11.11 Liability of the Board and the Committee. No member of the Board or the
Committee nor any Employee of the Company or any of its subsidiaries shall be liable for any act or
action hereunder, whether of omission or commission, by any other member or Employee or by any
agent to whom duties in connection with the administration of the Plan have been

16

 

delegated or, except in circumstances involving bad faith, gross negligence or fraud, for
anything done or omitted to be done by himself.

     11.12 Other Benefits. No payment pursuant to an Award shall be deemed compensation
for purposes of computing benefits under any retirement plan of the Company or any Subsidiary nor
affect any benefits under any other benefit plan now or hereafter in effect under which the
availability or amount of benefits is related to the level of compensation.

     11.13 Costs. The Company shall bear all expenses incurred in administering the Plan,
including expenses related to the issuance of Common Stock pursuant to Awards.

     11.14 Severability. If any part of the Plan shall be determined to be invalid or void
in any respect, such determination shall not affect, impair, invalidate or nullify the remaining
provisions of the Plan which shall continue in full force and effect.

     11.15 Successors. The Plan shall be binding upon and inure to the benefit of any
successor or successors of the Company.

     11.16 Headings. Article and section headings contained in the Plan are included for
convenience only and are not to be used in construing or interpreting the Plan.
