EXHIBIT 4.3    
    

WITNESS SYSTEMS, INC.

2003 BROAD BASED OPTION PLAN  

Section 1.

PURPOSE  

        The purpose of this Plan is to promote the interests of the Company by providing to Participants the opportunity to purchase Shares that have appreciated in value
in order to attract and retain Participants. The Plan can provide an incentive to work to increase the value of Shares and a stake in the future of the Company that corresponds to the interests of the
Company stockholders. The Plan is adopted in connection with the acquisition of Eyretel plc., by the Company in order to replace the stock incentive plan maintained by Eyretel plc. Initial grants will
be made to former Eyretel plc. employees to provide an inducement for such employees. The Plan provides for the grant of non-qualified stock options to aid the Company in reaching these
goals. It is the Company's intent that a majority of the Options granted under this Plan be granted to Employees other than Directors and officers of the Company, and that a
majority of the Participants be Employees other than Directors and officers.

EFFECTIVE DATE  

        The effective date of this Plan shall be the date it is adopted by the Board, as noted in resolutions effectuating such adoption. Stockholder approval shall not
be sought and shall not be required with respect to this Plan. Correspondingly, stockholder approval of specific grants of Options is necessary to meet the Performance-Based Exception. 

Section 5.

ADMINISTRATION  

        5.1    General Administration.    This Plan shall be administered by the Board. The Board,
acting in its absolute discretion, shall exercise such powers and take such action as expressly called for under this Plan. The Board shall have the power to interpret this Plan and, subject to the
terms and provisions of this Plan, to take such other action in the administration and operation of the Plan as it deems equitable under the circumstances. The Board's actions shall be binding on the
Company, on each affected Employee, and on each other person directly or indirectly affected by such actions. 

        5.2    Authority of the Board.    Except as limited by law or by the Certificate of
Incorporation or Bylaws of the Company, and subject to the provisions herein, the Board shall have full power to select Employees who shall participate in the Plan, to determine the sizes and types of
Options in a manner consistent with the Plan, to determine the terms and conditions of Options in a manner consistent with the Plan, to construe and interpret the Plan and any agreement or instrument
entered into under the Plan, to establish, amend or waive rules and regulations for the Plan's administration, and to amend the terms and conditions of any outstanding Options as allowed under the
Plan and such Options. Further, the Board may make all other determinations which may be necessary or advisable for the administration of the Plan. 

        5.3    Delegation of Authority.    The Board may delegate its authority under the Plan, in
whole or in part, to a Committee appointed by the Board consisting of not less than one (1) Director or to one or more other persons to whom the powers of the Board hereunder may be delegated
in accordance with applicable law. The members of the Committee and any other persons to whom authority has been delegated shall be appointed from time to time by, and shall serve at the discretion
of, the Board. The Committee or other delegate (if appointed) shall act according to the policies and procedures set forth in the Plan and to those policies and procedures established by the Board,
and the Committee or other delegate shall have such powers and responsibilities as are set forth by the Board. Reference to the Board in this Plan shall specifically include reference to the Committee
or other delegate where the Board has delegated its authority to the Committee or other delegate, and any action by the Committee or other delegate pursuant to a delegation of authority by the Board
shall be deemed an action by the Board under the Plan. Notwithstanding the above, the Board may assume the powers and responsibilities granted to the Committee or other delegate at any time, in whole
or in part. With respect to Committee appointments and composition, only a Committee (or a sub-committee thereof) comprised solely of two (2) or more Outside Directors may grant
Options that will meet the Performance-Based Exception, and only a Committee comprised solely of Non-Employee Directors may grant Options to Insiders that will be exempt from
Section 16(b) of the Exchange Act. 

        5.4    Decisions Binding.    All determinations and decisions made by the Board (or its
delegate) pursuant to the provisions of this Plan and all related orders and resolutions of the Board shall be final, conclusive and binding on all persons, including the Company, its stockholders,
Directors, Employees, Participants, and their estates and beneficiaries.

Section 6.

ELIGIBILITY  

        Employees selected by the Board shall be eligible for the grant of Options under this Plan, but no Employee shall have the right to be granted a Option under this
Plan merely as a result of his or her status as an Employee. It is the Company's intent that a majority of the Options granted under this Plan be granted to Employees other
than Directors and officers of the Company, and that a majority of the Participants be Employees other than Directors and
officers.

Section 7.

TERMS OF OPTIONS  

        7.1    General Terms and Conditions of All Options.

        (a)    Grants of Options.    The Board, in its absolute discretion, shall grant Options under this Plan from time to
time and shall have the right to grant new Options in exchange for outstanding Options. Options shall be granted to Employees selected by the Board, and the Board shall be under no obligation
whatsoever to grant Options to all Employees, or to grant all Options subject to the same terms and conditions. 

        (b)    Shares Subject to Options.    The number of Shares as to which a Option shall be granted shall be determined by
the Board in its sole discretion, subject to the provisions of Section 3 as to the total number of Shares available for grants under the Plan. 

        (c)    Option Agreements.    Each Option shall be evidenced by a Option Agreement executed by the Company, a Parent or
a Subsidiary, and the Participant, which shall be in such form and contain such
terms and conditions as the Board in its discretion may, subject to the provisions of the Plan, from time to time determine. 

        (d)    Date of Grant.    The date a Option is granted shall be the date on which the Board (1) has approved the
terms and conditions of the Option Agreement, (2) has determined the recipient of the Option and the number of Shares covered by the Option and (3) has taken all such other action
necessary to complete the grant of the Option. 

        7.2    Necessity of Option Agreements.    Each grant of an Option shall be evidenced by a Option Agreement that shall
specify that the Option is a non-qualified stock option, and incorporate such other terms and conditions as the Board, acting in its absolute discretion, deems consistent with the terms of
this Plan, including (without limitation) a restriction on the number of Shares subject to the Option that first become exercisable during any calendar year. 

        7.3    Determining Optionees.    In determining Employee(s) to whom an Option shall be granted and the number of
Shares to be covered by such Option, the Board may take into account the recommendations of the Chief Executive Officer of the Company and its other officers, the duties of the Employee, the present
and potential contributions of the Employee to the success of the Company, the anticipated number of years of service remaining before the attainment by the Employee of retirement age, and other
factors deemed relevant by the Board, in its sole discretion, in connection with accomplishing the purpose of this Plan. An Employee who has been granted an Option to purchase Shares, whether under
this Plan or otherwise, may be granted one or more additional Options. 

5

   
        7.4    Exercise Price.    Subject to adjustment in accordance with Section 10 and the other provisions
of this
Section, the Exercise Price shall be as set forth in the applicable Option Agreement. If a Option is an Option, the Exercise Price for each Share shall be no less than (1) the minimum price
required by applicable state law, or (2) the minimum price required by the Company's governing instrument, or (3) $0.01, whichever price is greater. Any Option intended to meet the
Performance-Based Exception must be granted with an Exercise Price equivalent to or greater than the Fair Market Value of the Shares subject thereto and must be separately approved by the Company's
stockholders. Any Option intended to meet the FLSA Exclusion must be granted with an Exercise Price equivalent to or greater than eighty-five percent (85%) of the Fair Market Value of the
Shares subject thereto on the date granted. 

        7.5    Option Term.    Each Option granted under this Plan shall be exercisable in whole or in
part at such time or times as set forth in the related Option Agreement, but no Option Agreement shall: 

	(a)
	make
an Option exercisable before the date such Option is granted; or

	(b)
	make
an Option exercisable after the earlier of:

	(i)
	the
date such Option is exercised in full, or

	(ii)
	the
date that is the tenth (10th) anniversary of the date such Option is granted. The exercise of an Option after the employment of an Employee has terminated for any
reason whatsoever, including death or disability, shall be effected in accordance with the terms and provisions of its Option Agreement. The Employee's rights, if any, upon termination of employment
will be set forth in the applicable Option Agreement. 

        7.6    Payment.    Options shall be exercised by the delivery of a written notice of exercise to the Company, setting
forth the number of Shares with respect to which the Option is to be exercised accompanied by full payment for the Shares. Payment for shares of Stock purchased pursuant to exercise of an Option
shall be made in cash to the Company or if so directed by the Company to any relevant trustee of an employee share trust or, unless the Option Agreement provides otherwise, by delivery to the Company
of a number of Shares that have been owned and completely paid for by the holder for at least six (6) months prior to the date of exercise (i.e.,
"mature shares" for accounting purposes) having an aggregate Fair Market Value equal to the amount to be tendered, or a combination thereof. In addition, if the Option Agreement so provides, the
Option may be exercised through a brokerage transaction following registration of the Company's equity securities under Section 12 of the Securities Exchange Act of 1934 as permitted under the
provisions of Regulation T applicable to cashless exercises promulgated by the Federal Reserve Board, unless prohibited by the Sarbanes-Oxley Act of 2002. However, notwithstanding the
foregoing, with respect to any Option recipient who is an Insider, a tender of shares or a cashless exercise must (1) have met the requirements of an exemption under
Rule 16b-3 promulgated under the Exchange Act, or (2) be a subsequent transaction the terms of which were provided for in a transaction initially meeting the requirements of
an exemption under Rule 16b-3 promulgated under the Exchange Act. Unless the Option Agreement provides otherwise, the foregoing exercise payment methods shall be deemed to be
subsequent transactions approved at the time of and by the original grant of an Option and shall not require separate approval. Except as provided in Subsection 7.7 below, payment shall be made at the
time that the Option or any part thereof is exercised, and no Shares shall be issued or delivered upon exercise of an Option until full payment has been made by the Participant. The holder of an
Option, as such, shall have none of the rights of a stockholder. 

        7.7    Conditions to Exercise of an Option.    Each Option granted under the Plan shall vest and shall be exercisable
at such time or times, or upon the occurrence of such event or events, and in such amounts, as the Board shall specify in the Option Agreement; provided, however, that subsequent to 

6

 

the
grant of an Option, the Board, at any time before complete termination of such Option, may accelerate the time or times at which such Option may vest or be exercised in whole or in part.
Notwithstanding the foregoing, an Option intended to meet the FLSA Exclusion shall not be exercisable for at least six (6) months following the date it is granted, except by reason of death,
disability, retirement, a change in corporate ownership or other circumstances permitted under regulations promulgated under the FLSA Exclusion. The Board may impose such restrictions on any Shares
acquired pursuant to the exercise of an Option as it may deem advisable, including, without limitation, vesting or performance-based restrictions, rights of the Company to re-purchase
Shares acquired pursuant to the exercise of an Option, voting restrictions, investment intent restrictions, restrictions on transfer, "first refusal" rights of the Company to purchase Shares acquired
pursuant to the exercise of an Option prior to their sale to any other person, "drag along" rights requiring the sale of shares to a third party purchaser in certain circumstances, "lock up" type
restrictions in the case of an initial public offering of the Company's stock, restrictions or limitations or other provisions that would be applied to stockholders under any applicable agreement
among the stockholders, and restrictions under applicable federal securities laws, under the requirements of any stock exchange or market upon which such Shares are then listed and/or traded, and/or
under any blue sky or state securities laws applicable to such Shares. 

        7.8    Transferability of Options.    An Option shall not be transferable or assignable except by will or by the laws
of descent and distribution and shall be exercisable, during the Participant's lifetime, only by the Participant; provided, however, that in the event the Participant is incapacitated and unable to
exercise
his or her Option, such Option may be exercised by such Participant's legal guardian, legal representative, or other representative whom the Board deems appropriate based on applicable facts and
circumstances. The determination of incapacity of a Participant and the determination of the appropriate representative of the Participant who shall be able to exercise the Option if the Participant
is incapacitated shall be determined by the Board in its sole and absolute discretion. Notwithstanding the foregoing, except as otherwise provided in the Option Agreement, an Option may also be
transferred by a Participant as a bona fide gift (i) to his spouse, child, grandchild, stepchild, and children by adoption, brother or sister, parent, step-parent, grandparent, or
mother, father, brother or sister-in-law (ii) to a trust for the benefit of one or more individuals described in clause (i) and no other persons, or
(iii) to a partnership of which the only partners are one or more individuals described in clause (i), in which case the transferee shall be subject to all provisions of the Plan, the
Option Agreement and other agreements with the Participant in connection with the exercise of the Option and purchase of Shares. In the event of such a gift, the Participant shall promptly notify the
Board of such transfer and deliver to the Board such written documentation as the Board may in its discretion request, including, without limitation, the written acknowledgment of the donee that the
donee is subject to the provisions of the Plan, the Option Agreement and other agreements with the Participant. 

        7.9    Special Provisions for Certain Substitute Options.    Notwithstanding anything to the contrary in this Section,
any Option in substitution for a stock option previously issued by another entity, which substitution occurs in connection with a transaction to which Code §424(a) is applicable, may
provide for an exercise price computed in accordance with Code §424(a) and the regulations thereunder and may contain such other terms and conditions as the Board may prescribe to cause
such substitute Option to contain as nearly as possible the same terms and conditions (including the applicable vesting and termination provisions) as those contained in the previously issued stock
option being replaced thereby. 

Section 8.

SECURITIES REGULATION  

        Each Option Agreement may provide that, upon the receipt of Shares as a result of the exercise of a Option or otherwise, the Participant shall, if so requested by
the Company, hold such Shares for 

7

 

investment
and not with a view of resale or distribution to the public and, if so requested by the Company, shall deliver to the Company a written statement satisfactory to the Company to that effect.
Each Option Agreement may also provide that, if so requested by the Company, the Participant shall make a written representation to the Company that he or she will not sell or offer to sell any of
such Shares unless a registration statement shall be in effect with respect to such Shares under the Securities Act of 1933, as amended ("1933 Act"), and any applicable state securities law or, unless
he or she shall have furnished to the Company an opinion, in form and substance satisfactory to the Company, of legal counsel acceptable to the Company, that such registration is not required.
Certificates representing the Shares transferred upon the exercise of a Option granted under this Plan may at the discretion of the Company bear a legend to the effect that such Shares have not been
registered under the 1933 Act or any applicable state securities law and that such Shares may not be sold or offered for sale in the absence of an effective registration statement as to such Shares
under the 1933 Act and any applicable state securities law or an opinion, in form and substance satisfactory to the Company, of legal counsel acceptable to the Company, that such registration is not
required. 

Section 9.

LIFE OF PLAN  

        No Option shall be granted under this Plan on or after the earlier of: 

        (a)
the tenth (10th) anniversary of the effective date of this Plan (as determined under Section 4 of this Plan), in which event this Plan thereafter shall continue in effect
until all outstanding Options have been exercised in full or no longer are exercisable, or 

        (b)
the date on which all of the Shares reserved under Section 3 of this Plan have (as a result of the exercise of Options granted under this Plan) been issued or no longer are
available for use under this Plan, in which event this Plan also shall terminate on such date. 

Section 10.

ADJUSTMENT  

        Notwithstanding anything in Section 12 to the contrary, the number of Shares reserved under Section 3 of this Plan, the limit on the number of
Shares that may be granted during a calendar year to any individual under Section 3 of this Plan, and the number of Shares subject to Options granted under this Plan, shall be adjusted by the
Board in an equitable manner to reflect any change in the capitalization of the Company, including, but not limited to, such changes as stock dividends or stock splits. Furthermore, the Board shall
have the right to adjust (in a manner that satisfies the requirements of Code §424(a)) the number of Shares reserved under Section 3, and the number of Shares subject to Options
granted under this Plan, and the Exercise Price of any Options in the event of any corporate transaction described in Code §424(a) that provides for the substitution or assumption of such
Options. If any adjustment under this Section creates a fractional Share or a right to acquire a fractional Share, such fractional Share shall be disregarded, and the number of Shares reserved under
this Plan and the number subject to any Options granted under this Plan shall be the next lower number of Shares, rounding all fractions downward. An adjustment made under this Section by the Board
shall be conclusive and binding on all affected persons and, further, shall not constitute an increase in the number of Shares reserved under Section 3. 

Section 11.

CHANGE OF CONTROL OF THE COMPANY  

        Except as otherwise provided in a Option Agreement, if a Change of Control occurs, and if the agreements effectuating the Change of Control do not provide for the
assumption or substitution of all Options granted under this Plan, with respect to any Option granted under this Plan that is not so 

8

 

assumed
or substituted (a "Non-Assumed Option"), the Committee, in its sole and absolute discretion, may, with respect to any or all of such Non-Assumed Options, take any or
all of the following actions to be effective as of the date of the Change of Control (or as of any other date fixed by the Committee occurring within the thirty (30) day period immediately
preceding the date of the Change of Control, but only if such action remains contingent upon the effectuation of the Change of Control) (such date referred to as the "Action Effective Date"): 

	(a)
	Accelerate
the vesting and/or exercisability of such Non-Assumed Option; and/or

	(b)
	Unilaterally
cancel such Non-Assumed Option in exchange for:

	(i)
	whole
and/or fractional Shares (or for whole Shares and cash in lieu of any fractional Share) or whole and/or fractional shares of a successor (or for whole shares of a
successor and cash in lieu of any fractional share) that, in the aggregate, are equal in value to the excess of the Fair Market Value of the Shares that could be purchased subject to such
Non-Assumed Option determined as of the Action Effective Date (taking into account vesting) over the aggregate Exercise Price for such Shares; or

	(ii)
	cash
or other property equal in value to the excess of the Fair Market Value of the Shares that could be purchased subject to such Non-Assumed Option
determined as of the Action Effective Date (taking into account vesting) over the aggregate Exercise Price for such Shares. 

However,
notwithstanding the foregoing, to the extent that the recipient of a Non-Assumed Option is an Insider, payment of cash in lieu of whole or fractional Shares or shares of a
successor may only be made to the extent that such payment (1) has met the requirements of an exemption under Rule 16b-3 promulgated under the Exchange Act, or (2) is
a subsequent transaction the terms of which were provided for in a transaction initially meeting the requirements of an exemption under Rule 16b-3 promulgated under the Exchange
Act. Unless a Option Agreement provides otherwise, the payment of cash in lieu of whole or fractional Shares or in lieu of whole or fractional shares of a successor shall be considered a subsequent
transaction approved by the original grant of an Option. 

Section 12.

AMENDMENT OR TERMINATION  

        This Plan may be amended by the Board from time to time to the extent that the Board deems necessary or appropriate; provided, however, no such amendment shall be
made absent the approval of the stockholders of the Company (a) to increase the number of Shares reserved under Section 3, except as set forth in Section 10, (b) to extend
the maximum life of the Plan under Section 9 or the maximum exercise period under Section 7, (c) to decrease the minimum Exercise Price under Section 7, or (d) to
change the designation of Employees eligible for Options under Section 6. The Board also may suspend the granting of Options under this Plan at any time and may terminate this Plan at any time.
The Company shall have the right to modify, amend or cancel any Option after it has been granted if (I) the modification, amendment or cancellation does not diminish the rights or benefits of
the Option recipient under the Option (provided, however, that a modification, amendment or cancellation that results solely in a change in the tax consequences with respect to a Option shall not be
deemed as a diminishment of rights or benefits of such Option), (II) the Participant consents in writing to such modification, amendment or cancellation, (III) there is a dissolution or
liquidation of the Company, (IV) this Plan and/or the Option Agreement expressly provides for such modification, amendment or cancellation, or (V) the Company would otherwise have the
right to make such modification, amendment or cancellation by applicable law.

MISCELLANEOUS  

        13.1    Stockholder Rights.    No Participant shall have any rights as a stockholder of the Company as a result of the
grant of a Option to him or to her under this Plan or his or her exercise of such Option pending the actual delivery of Shares subject to such Option to such Participant. 

        13.2    No Guarantee of Continued Relationship.    The grant of a Option to a Participant under this Plan shall not
constitute a contract of employment and shall not confer on a Participant any rights upon his or her termination of employment or relationship with the Company in addition to those rights, if any,
expressly set forth in the Option Agreement that evidences his or her Option. 

        13.3    Withholding.    The Company shall have the power and the right to deduct or withhold, or require a Participant
to remit to the Company as a condition precedent for the fulfillment of any Option, an amount sufficient to satisfy any US federal, state and local taxes and any UK tax and national insurance
contributions and any other domestic or foreign taxes or social security contributions,
required by law or regulation to be withheld with respect to any taxable event arising as a result of this Plan and/or any action taken by a Participant with respect to a Option. Whenever Shares are
to be issued to a Participant upon exercise of an Option, the Company shall have the right to require the Participant to remit to the Company, as a condition of exercise of the Option, an amount in
cash (or, unless the Option Agreement provides otherwise, in Shares) sufficient to satisfy any US federal, state and local taxes and any UK tax and national insurance contributions and any other
domestic or foreign taxes or social security contributions at the time of exercise. However, notwithstanding the foregoing, to the extent that a Participant is an Insider, satisfaction of withholding
requirements by having the Company withhold Shares may only be made to the extent that such withholding of Shares (1) has met the requirements of an exemption under
Rule 16b-3 promulgated under the Exchange Act, or (2) is a subsequent transaction the terms of which were provided for in a transaction initially meeting the requirements of
an exemption under Rule 16b-3 promulgated under the Exchange Act. Unless the Option Agreement provides otherwise, the withholding of shares to satisfy federal, state and local
withholding tax requirements shall be a subsequent transaction approved by the original grant of a Option. Notwithstanding the foregoing, in no event shall payment of withholding taxes be made by a
retention of Shares by the Company unless the Company retains only Shares with a Fair Market Value equal to the minimum amount of taxes required to be withheld. 

        13.4    Transfer.    The transfer of an Employee between or among the Company, a Subsidiary or a Parent shall not be
treated as a termination of his or her employment under this Plan. 

        13.5    Construction.    This Plan shall be construed under the laws of the State of Delaware.

Section 7

TERMS OF OPTIONS  

        7.1    Terms of Options.    No Option shall: 

        (a)   be
exercisable before the date such Option is granted; or 

        (b)   be
exercisable after the earlier of (A) the date such Option is exercised in full, or (B) the date that is the tenth (10th) anniversary of the date such
Option is granted. 

An
Option shall be immediately forfeited and may not be exercised after the date which is twelve (12) months after Optionee ceases to perform services for the Company as a member of the Board
of Directors of the Company for any reason, but in no event later than the Expiration Date; provided, however, if the Optionee ceases to perform services for the Company as a member of the Board of
Directors of the Company for Cause, this Option shall immediately be forfeited, as of the date of such cessation of performing services, but in no event later than the Expiration Date. The Board shall
have discretion to determine whether Optionee has ceased to perform services for the Company as a member of the Board of Directors of the Company. 

        7.2    Exercise Price.    Subject to adjustment in accordance with Section 10 and the
other provisions of this Section, the Exercise Price shall be as set forth in the applicable Option Agreement. With respect to each Option, the Exercise Price of such Option shall be equal to the Fair
Market Value of a Share on the date the Option is granted. 

        7.3    Payment.    Options shall be exercised by the delivery of a written notice of exercise
to the Company, setting forth the number of Shares with respect to which the Option is to be exercised accompanied by full payment for the Shares. Payment for shares of Stock purchased pursuant to
exercise of an Option shall be made in cash or, unless the Option Agreement provides otherwise, by delivery to the Company of a number of Shares that have been owned and completely paid for by the
holder for at least six (6) months prior to the date of exercise (i.e., "mature shares" for accounting purposes) having an aggregate Fair Market
Value equal to the amount to be tendered, or a combination thereof. In addition, unless the Option Agreement provides otherwise, the Option may be exercised through a brokerage transaction following
registration of the Company's equity securities under Section 12 of the Securities Exchange Act of 1934 as permitted under the provisions of Regulation T applicable to cashless exercises
promulgated by the Federal Reserve Board, unless prohibited by the Sarbanes-Oxley Act of 2002. However, notwithstanding the foregoing, with respect to any Option recipient who is an Insider, a tender
of shares or a cashless exercise must (1) have met the requirements of an exemption under Rule 16b-3 promulgated under the Exchange Act, or (2) be a subsequent
transaction the terms of which were provided for in a transaction initially meeting the requirements of an exemption under Rule 16b-3 promulgated under the Exchange Act. Unless the
Option Agreement provides otherwise, the foregoing exercise payment methods shall be subsequent transactions approved by the original grant of an Option. Except as provided in subparagraph
(d) below, payment shall be made at the time that the Option or any part thereof is exercised, and no Shares shall be issued or delivered upon exercise of an Option until full payment has been
made by the Participant. The holder of an Option, as such, shall have none of the rights of a stockholder. Notwithstanding the above, and in the sole discretion of the Board, an Option may be
exercised as to a portion or all (as determined by the Board) of the number of Shares specified in the Option Agreement by delivery to the Company of a promissory note, such promissory note to be
executed by the Participant and that shall include, with such other terms and conditions as the Board shall determine, provisions in a form approved by the Board under which: (i) the balance of
the aggregate purchase price shall be payable in equal installments over such period and shall bear interest at such rate (that shall not be less than the prime bank loan rate as determined by the
Board, that shall be established at the time of exercise, and that must be a market rate based on the rate environment at the date of exercise) as the Board shall approve, and (ii) the
Participant shall be personally liable for 

5

 

payment
of the unpaid principal balance and all accrued but unpaid interest. Other methods of payment may also be used if approved by the Board in its sole and absolute discretion and provided for
under the Option Agreement. 

        7.4    Conditions to Exercise of an Option.    Each Option granted under the Plan shall
provide that the Optionee shall be entitled to purchase, pursuant to the exercise of this Option, the percentage of the Shares subject to this Option shown below based upon the Continuous Service of
the Optionee from the date of grant of the Option at the time of exercise (provided, however, that subsequent to the grant of an Option, the Board, at any time before complete termination of such
Option, may accelerate the time or times at which such Option may vest or be exercised in whole or in part): 

VESTING SCHEDULE:  

	Percentage Vested:
 
	 	Continuous Service:

	0%	 	Less than 3 months
	12.5%	 	At least 3 months, but less than 6 months
	25%	 	At least 6 months, but less than 9 months
	37.5%	 	At least 9 months, but less than 12 months
	50%	 	At least 12 months, but less than 15 months
	62.5%	 	At least 15 months, but less than 18 months
	75%	 	At least 18 months, but less than 21 months
	87.5%	 	At least 21 months, but less than 24 months
	100%	 	At least 24 months

However,
notwithstanding the foregoing, in the event that the Optionee resigns from the Board of Directors of the Company at the written request of the Chairman of the Board of Directors of the
Company, then the Optionee shall be entitled to purchase, pursuant to the exercise of this Option, the percentage of the Shares subject to this Option shown below based upon the Continuous Service of
the Optionee from the Grant Date of this Option (as noted hereon) at the time of exercise: 

VESTING SCHEDULE:  

	Percentage Vested:
 
	 	Continuous Service:

	50%	 	Less than 3 months
	56.25%	 	At least 3 months, but less than 6 months
	62.5%	 	At least 6 months, but less than 9 months
	68.75%	 	At least 9 months, but less than 12 months
	75%	 	At least 12 months, but less than 15 months
	81.25%	 	At least 15 months, but less than 18 months
	87.5%	 	At least 18 months, but less than 21 months
	93.75%	 	At least 21 months, but less than 24 months
	100%	 	At least 24 months

Furthermore,
in the event that a Change of Control occurs, then, notwithstanding any provision of the foregoing to the contrary, if the Optionee has not ceased to perform Continuous Service prior to
the occurrence of such Change of Control, an Optionee shall be entitled to exercise 100% of the Shares subject to an Option from and after the occurrence of such Change of Control during any remaining
term of such Option. 

        7.5    Restrictions on Shares Acquired.    The Board may impose such restrictions on any
Shares acquired pursuant to the exercise of an Option as it may deem advisable, including, without limitation, vesting or performance-based restrictions, rights of the Company to
re-purchase Shares acquired pursuant to the exercise of an Option, voting restrictions, investment intent restrictions, restrictions on 

6

 

transfer,
"first refusal" rights of the Company to purchase Shares acquired pursuant to the exercise of an Option prior to their sale to any other person, "drag along" rights requiring the sale of
shares to a third party purchaser in certain circumstances, "lock up" type restrictions in the case of an initial public offering of the Company's stock, restrictions or limitations or other
provisions that would be applied to stockholders under any applicable agreement among the stockholders, and restrictions under applicable federal securities laws, under the requirements of any stock
exchange or market upon which such Shares are then listed and/or traded, and/or under any blue sky or state securities laws applicable to such Shares. 

        7.6    Transferability of Options.    An Option shall not be transferable or assignable except
by will or by the laws of descent and distribution and shall be exercisable, during the Participant's lifetime, only by the Participant; provided, however, that in the event the Participant is
incapacitated and unable to exercise his or her Option, such Option may be exercised by such Participant's legal guardian, legal representative, or other representative whom the Board deems
appropriate based on applicable facts and circumstances. The determination of incapacity of a Participant and the determination of the appropriate representative of the Participant who shall be able
to exercise the Option if the Participant is incapacitated shall be determined by the Board in its sole and absolute discretion. Notwithstanding the foregoing, except as otherwise provided in the
Option Agreement, an Option may also be transferred by a Participant as a bona fide gift (i) to his spouse, lineal descendant or lineal ascendant, siblings and children by adoption,
(ii) to a trust for the benefit of one or more individuals described in clause (i) and no other persons, or (iii) to a partnership of which the only partners are one or more
individuals described in clause (i), in which case the transferee shall be subject to all provisions of the Plan, the Option Agreement and other agreements with the Participant in connection
with the exercise of the Option and purchase of Shares. In the event of such a gift, the Participant shall promptly notify the Board of such transfer and deliver to the Board such written
documentation as the Board may in its discretion request, including, without limitation, the written acknowledgment of the donee that the donee is subject to the provisions of the Plan, the Option
Agreement and other agreements with the Participant. 

Section 8.

SECURITIES REGULATION  

        Each Option Agreement may provide that, upon the receipt of Shares as a result of the exercise of a Option or otherwise, the Participant shall, if so requested by
the Company, hold such Shares for investment and not with a view of resale or distribution to the public and, if so requested by the Company, shall deliver to the Company a written statement
satisfactory to the Company to that effect. Each Option Agreement may also provide that, if so requested by the Company, the Participant shall make a written representation to the Company that he or
she will not sell or offer to sell any of such Shares unless a registration statement shall be in effect with respect to such Shares under the Securities Act of 1933, as amended ("1933 Act"), and any
applicable state securities law or, unless he or she shall have furnished to the Company an opinion, in form and substance satisfactory to the Company, of legal counsel acceptable to the Company, that
such registration is not required. Certificates representing the Shares transferred upon the exercise of a Option granted under this Plan may at the discretion of the Company bear a legend to the
effect that such Shares have not been registered under the 1933 Act or any applicable state securities law and that such Shares may not be sold or offered for sale in the absence of an effective
registration statement as to such Shares under the 1933 Act and any applicable state securities law or an opinion, in form and substance satisfactory to the Company, of legal counsel acceptable to the
Company, that such registration is not required.

Section 9.

LIFE OF PLAN  

        No Option shall be granted under this Plan on or after the earlier of: 

        (a)   the
tenth (10th) anniversary of the effective date of this Plan (as determined under Section 4 of this Plan), in which event this Plan otherwise thereafter shall
continue in effect until all outstanding Options have been exercised in full or no longer are exercisable, or 

        (b)   the
date on which all of the Shares reserved under Section 3 of this Plan have (as a result of the exercise of Options granted under this Plan) been issued or no
longer are available for use under this Plan, in which event this Plan also shall terminate on such date. 

Section 10.

ADJUSTMENT  

        Notwithstanding anything in Section 12 to the contrary, the number of Shares reserved under Section 3 of this Plan, the number of Shares subject to
Options granted under this Plan, and the Exercise Price of any Options, shall be adjusted by the Board in an equitable manner to reflect any change in the capitalization of the Company, including, but
not limited to, such changes as stock dividends or stock splits. Furthermore, the Board shall have the right to adjust (in a manner that satisfies the requirements of Code §424(a) as if
such Code section applied to the situation) the number of Shares reserved under Section 3, and the number of Shares subject to Options granted under this Plan, and the Exercise Price of any
Options in the event of any corporate transaction described in Code §424(a) that provides for the substitution or assumption of such Options. If any adjustment under this Section creates a
fractional Share or a right to acquire a fractional Share, such fractional Share shall be disregarded, and the number of Shares reserved under this Plan and the number subject to any Options granted
under this Plan shall be the next lower number of Shares, rounding all fractions downward. An adjustment made under this Section by the Board shall be conclusive and binding on all affected persons
and, further, shall not constitute an increase in the number of Shares reserved under Section 3. 

Section 11.

SALE OR MERGER OF THE COMPANY  

        If a Change of Control occurs, and if the agreements effectuating the Change of Control do not provide for the assumption or substitution of all Options granted
under this Plan, with respect to any Option granted under this Plan that is not so assumed or substituted (a "Non-Assumed Option"), the Board, in its sole and absolute discretion, may,
with respect to any or all of such Non-Assumed Options, take any or all of the following actions to be effective as of the date of the Change of Control (or as of any other date fixed by
the Board occurring within the thirty (30) day period immediately preceding the date of the Change of Control, but only if such action remains contingent upon the effectuation of the Change of
Control) (such date referred to as the "Action Effective Date"): 

        (a)   Accelerate
the vesting and/or exercisability of such Non-Assumed Option (to the extent not otherwise accelerated by the terms and provisions of this Plan);
and/or 

        (b)   Unilaterally
cancel such Non-Assumed Option in exchange for: 

        (iii)  whole
and/or fractional Shares (or for whole Shares and cash in lieu of any fractional Share) or whole and/or fractional shares of a successor (or for whole shares of
a successor and cash in lieu of any fractional share) that, in the aggregate, are equal in value to the excess of the Fair Market Value of the Shares that could be purchased subject to such
Non-Assumed Option determined as of the Action Effective Date (taking into account vesting) over the aggregate Exercise Price for such Shares; or

        (iv)  cash
or other property equal in value to the excess of the Fair Market Value of the Shares that could be purchased subject to such Non-Assumed Option
determined as of the Action Effective Date (taking into account vesting) over the aggregate Exercise Price for such Shares. 

However,
notwithstanding the foregoing, to the extent that the recipient of Non-Assumed Option is an Insider, payment of cash in lieu of whole or fractional Shares or shares of a successor
may only be made to the extent that such payment (1) has met the requirements of an exemption under Rule 16b-3 promulgated under the Exchange Act, or (2) is a
subsequent transaction the terms of which were provided for in a transaction initially meeting the requirements of an exemption under Rule 16b-3 promulgated under the Exchange Act.
Unless an Option Agreement provides otherwise, the payment of cash in lieu of whole or fractional Shares or in lieu of whole or fractional shares of a successor shall be considered a subsequent
transaction approved by the original grant of an Option. 

Section 12.

AMENDMENT OR TERMINATION  

        This Plan may be amended by the Board from time to time to the extent that the Board deems necessary or appropriate; provided, however, no such amendment shall be
made absent the approval of the stockholders of the Company (a) to increase the number of Shares reserved under Section 3, except as set forth in Section 10, (b) to extend
the maximum life of the Plan under Section 9 or the maximum exercise period under Section 7, (c) to decrease the minimum Exercise Price under Section 7, or (d) to
change the formula grant provisions (including, but not limited to, the Eligible Recipients eligible for grants of Options and the number of Shares subject to Options granted hereunder) under this
Plan. The Board also may suspend the granting of Options under this Plan at any time and may terminate this Plan at any time. The Company shall have the right to modify, amend or cancel any Option
after it has been granted if (I) the modification, amendment or cancellation does not diminish the rights or benefits of the Option recipient under the Option (provided, however, that a
modification, amendment or cancellation that results solely in a change in the tax consequences with respect to a Option shall not be deemed as a diminishment of rights or benefits of such Option),
(II) the Participant consents in writing to such modification, amendment or cancellation, (III) there is a dissolution or liquidation of the Company, (IV) this Plan and/or the
Option Agreement expressly provides for such modification, amendment or cancellation, or (V) the Company would otherwise have the right to make such modification, amendment or cancellation by
applicable law. 

Section 13.

MISCELLANEOUS  

        13.6    Stockholder Rights.    No Participant shall have any rights as a stockholder of the
Company as a result of the grant of a Option to him or to her under this Plan or his or her exercise of such Option pending the actual delivery of Shares subject to such Option to such Participant. 

        13.7    No Guarantee of Continued Relationship.    The grant of a Option to a Participant
under this Plan shall not constitute a contract of employment and shall not confer on a Participant any rights upon his or her termination of employment or other relationship with the Company in
addition to those rights, if any, expressly set forth in the Option Agreement that evidences his or her Option. 

        13.8    Withholding.    The Company shall have the power and the right to deduct or withhold,
or require a Participant to remit to the Company as a condition precedent for the fulfillment of any Option, an amount sufficient to satisfy Federal, state and local taxes, domestic or foreign,
required by law or regulation to be withheld with respect to any taxable event arising as a result of this Plan and/or any action taken by a Participant with respect to a Option. Whenever Shares are
to be issued to a Participant upon exercise of an Option, the Company shall have the right to require the Participant to 

9

 

remit
to the Company, as a condition of exercise of the Option, an amount in cash (or, unless the Option Agreement provides otherwise, in Shares) sufficient to satisfy federal, state and local
withholding tax requirements at the time of exercise. However, notwithstanding the foregoing, to the extent that a Participant is an Insider, satisfaction of withholding requirements by having the
Company withhold Shares may only be made to the extent that such withholding of Shares (1) has met the requirements of an exemption under Rule 16b-3 promulgated under the
Exchange Act, or (2) is a subsequent transaction the terms of which were provided for in a transaction initially meeting the requirements of an exemption under Rule 16b-3
promulgated under the Exchange Act. Unless the Option Agreement provides otherwise, the withholding of shares to satisfy federal, state and local withholding tax requirements shall be a subsequent
transaction approved by the original grant of a Option. Notwithstanding the foregoing, in no event shall payment of withholding taxes be made by a retention of Shares by the Company unless the Company
retains only Shares with a Fair Market Value equal to the minimum amount of taxes required to be withheld. 

        13.9    Construction.    This Plan shall be construed under the laws of the State of Delaware.
