Exhibit 10.61

SEVERANCE COMPENSATION AGREEMENT
Dated as of July 11, 2001
Between
DATUM INC., a Delaware corporation, (the Company)
And
Ilan Havered (the Executive)

The Companys Board of Directors (the Board) has determined that it is
appropriate to reinforce and encourage the continued attention and dedication
of members of the Companys management, including the Executive, to their
assigned duties without distraction in potentially disturbing circumstances
arising from the possibility of a change in control of the Company.

This Agreement sets forth the severance compensation which the Company
agrees it will pay to the Executive if the Executives employment with the
Company terminates under one of the circumstances described herein following a
Change in Control of the Company (as defined in Section 2).

1. Term. The term (Term) of this Agreement shall commence on the date
hereof and, subject to earlier termination pursuant to Section 3(b), 3(c) or
3(d) hereof, shall end three (3) years following the date on which notice of
non-renewal or termination of this Agreement is given by either the Company or
Executive to the other. Thus, this Agreement shall be renewable automatically
on a daily basis so that the outstanding Term is always three (3) years
following any effective notice of non-renewal or of termination given by the
Company or Executive.

2. Change in Control. No compensation shall be payable under this
Agreement unless and until (a) there has been a Change in Control of the
Company while the Executive is still an employee of the Company and (b) the
Executives employment by the Company terminates in the circumstances specified
in Section 3(a). For purposes of this Agreement, a Change in Control of the
Company shall be deemed to have occurred if (i) there shall be consummated (x)
any consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which shares of the
Companys Common Stock would be converted into cash, securities or other
property, other than a consolidation or merger of the Company in which the
holders of the Companys Common Stock immediately prior to the consolidation or
merger have substantially the same proportionate ownership of at least 65% of
common stock of the surviving corporation immediately after the consolidation
or merger, or (y) any sale, lease, exchange or other transfer (in one
transaction or a series of related transactions) of all, or substantially all,
of the assets of the Company other than to a corporation in which the holders
of the Companys Common Stock immediately prior to such transaction have
substantially the same proportionate ownership of at least 65% of the common
stock of such corporation, or (ii) the stockholders of the Company approve any
plan or proposal for the liquidation or dissolution of the Company, or (iii)
any person (as such term is used in Sections 13(d) and 14(d)(2) of the
Securities Exchange Act of 1934, as amended (the Exchange Act)), shall become
the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act)
of more than 35% of the Companys outstanding shares of Common Stock, or (iv)
during any period of two consecutive years during the term of this Agreement,
individuals who at the beginning of the two (2) year period constituted the
entire Board do not for any reason constitute a majority thereof unless the
election, or the nomination for election by the Companys stockholders,

of each new director was approved by a vote of at least five-eighths of
the directors then still in office who were directors at the beginning of the
period.

3. Termination Following Change in Control.

(a) Termination. If a Change in Control of the Company shall have
occurred while the Executive is still an employee of the Company, the Executive
shall be entitled to the compensation provided in Section 4 upon the subsequent
termination of the Executives employment with the Company within twenty-four
(24) months of such Change in Control, whether requested by the Executive or by
the Company, unless such termination is as a result of (i) the Executives
death; (ii) the Executives Disability (as defined in Section (3)(b) below);
(iii) the Executives Retirement (as defined in Section 3(c) below); (iv) the
Executives termination by the Company for Cause (as defined in Section 3(d)
below); or (v) the Executives decision to terminate employment other than for
Good Reason (as defined in Section 3(e) below).

(b) Death or Disability. If, as a result of the Executives incapacity
due to physical or mental illness, the Executive is absent from his duties with
the Company on a full-time basis for six (6) months, the Company may elect to
terminate the Executive for Disability by written notice to Executive and
without liability to Executive pursuant to this Agreement; provided, however,
that any such termination shall be effective only at the end of thirty (30)
days following the delivery of such notice and only if Executive fails to
return to the full-time performance of duties by the end of such 30-day notice
period. In addition, this Agreement shall terminate immediately in the event
of the death of the Executive occurring at any time during the Term hereof, and
in such event the Company shall have no liability by reason of such
termination.

(c) Retirement. The Executive shall be deemed terminated automatically,
without liability to Executive pursuant to this Agreement, upon Retirement (as
hereinafter defined) of Executive without liability to the Company pursuant to
this Agreement. Retirement as used in this Agreement shall be deemed to
occur upon the Executives having reached such age as shall have been fixed in
any arrangement mutually established by the Company and the Executive.

(d) Cause. The Company may terminate the Executive, without liability to
the Executive pursuant to this Agreement, if the Executives employment with
the Company is terminated for Cause. For purposes solely of determining
whether the Company may terminate the Executive pursuant to this Section 3(d)
without liability to the Executive, the Executive shall be deemed to have been
terminated for Cause only if Executive had engaged in fraud, misappropriation
or embezzlement, or any conviction or admission of a felony or other offense
involving dishonest or moral turpitude. Notwithstanding the foregoing, the
Executive shall not be deemed, for purposes of this Agreement, to have been
terminated for Cause unless and until there shall have been delivered to the
Executive a copy of a resolution duly adopted by the affirmative vote of not
less than five-eighths of the entire membership of the Companys Board at a
meeting of the Board called and held for that purpose (after reasonable notice
to the Executive and an opportunity for the Executive, together with the
Executives counsel, to be heard before the Board), finding that in the good
faith opinion of the Board the Executive was guilty of conduct set forth in the
second sentence of this Section 3(d) and specifying the particulars thereof in
detail.

(e) Good Reason. The Executive may terminate the Executives employment
for Good Reason at any time after a Change in Control during the Term. For
purposes of this Agreement, Good Reason shall mean any of the following:

(i) The Company has materially changed the Executives position, duties,
responsibilities, status, or offices as in effect immediately prior to a Change
in Control of the Company, or has removed the Executive from or failed to
reelect the Executive to any of such positions;

(ii) A reduction by the Company in the Executives base salary as in
effect on the date hereof or as the same may be increased from time to time
during the Term;

(iii) Any failure by the Company to continue in effect any benefit plan or
arrangement (including, without limitation, the Companys life insurance,
accident, disability and health insurance plans, 401(k) and bonus plans, stock
options, and all other similar plans which are from time to time made generally
available to senior executives/officers of the Company) and in which the
Executive is participating at the time of a Change in Control of the Company,
unless there are substituted therefore plans or arrangements providing the
Executive with essentially equivalent and no less favorable benefits
(hereinafter referred to as Benefit Plans), or the taking of any action by
the Company which would adversely affect the Executives participation in or
materially reduce the Executives benefits under any such Benefit Plan or
deprive the Executive of any material fringe benefit enjoyed by the Executive
at the time of a Change in Control of the Company;

(iv) Any failure by the Company to continue in effect any incentive plan
or arrangement (including, without limitation, the Companys plans enumerated
in subparagraph (iii) above and similar incentive compensation benefits) in
which the Executive is participating at the time of a Change in Control of the
Company, unless there are substituted therefore plans or arrangements providing
the Executive with essentially equivalent and no less favorable benefits
(hereinafter referred to as Incentive Plans), or the taking of any action by
the Company which would adversely affect the Executives participation in any
such Incentive Plan or reduce the Executives potential benefits under any such
Incentive Plan, expressed as a percentage of his base salary, by more than ten
(10) percentage points in any fiscal year as compared to the immediately
preceding fiscal year;

(v) Any failure by the Company to continue in effect any plan or
arrangement to receive securities of the Company (including, without
limitation, the Companys stock option and purchase plans and any other plan or
arrangement to receive and exercise stock options, stock appreciation rights,
restricted stock or grants thereof) in which the Executive is participating at
the time of a Change in Control of the Company, unless there are substituted
therefor plans or arrangements providing the Executive with essentially
equivalent and no less favorable (hereinafter referred to as Securities
Plans), or the taking of any action by the Company which would adversely
affect the Executives participation in or materially reduce the Executives
benefits under any such Securities Plan;

(vi) A relocation of the Companys principal executive offices to a
location outside of Orange County, California, or the Executives relocation to
any place other than the location at which the Executive performed the
Executives duties prior to a Change in Control of the Company, except for
required travel by the Executive on the Companys business to an extent

substantially consistent with the Executives business travel obligations
during the twelve (12) months immediately preceding a Change of Control of the
Company;

(vii) Any failure by the Company to provide the Executive with the number
of paid vacation days to which the Executive is entitled at the time of a
Change of Control of the Company;

(viii) Any material breach by the Company of any provision of this
Agreement;

(ix) Any failure by the Company to obtain the assumption of this Agreement
by any successor or assignee of the Company; or

(x) Any purported termination of the Executives employment that is not
effected pursuant to a Notice of Termination satisfying the requirements of
Section 3(f), and for purposes of this Agreement, no such purported termination
shall be effective.

(f) Notice of Termination. Any termination of the Executive by the
Company for Disability pursuant to Section 3(b) or for Cause pursuant to
Section 3(d) shall be communicated by a Notice of Termination. For purposes of
this Agreement, a Notice of Termination shall mean a written notice which
shall indicate those specific termination provisions in this Agreement relied
upon and which set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executives employment under
the provisions so indicated. For purposes of this Agreement, no such purported
termination by the Company shall be effective without such Notice of
Termination.

(g) Date of Termination. Date of Termination shall mean (i) if the
Executive is terminated by the Company for Disability, thirty (30) days after
Notice of Termination is given to the Executive (provided that the Executive
shall not have returned to the performance of the Executives duties on a
full-time basis during such 30-day period) or (ii) if the Executive is
terminated by the Company for any other reason, the date on which a Notice of
Termination is given; provided that if within thirty (30) days after any Notice
of Termination is given to the Executive by the Company the Executive notifies
the Company that a dispute exists concerning the termination, the Date of
Termination shall be the date the dispute is finally determined, whether by
mutual agreement by the parties or upon final judgment, order or decree of a
court of competent jurisdiction (the time for appeal therefrom having expired
and no appeal having been perfected).

4. Severance Compensation upon Termination of Employment. Subject to
Section 4(e) below, if, within twenty-four (24) months following a Change in
Control, the Company shall terminate the Executives employment other than
pursuant to Section 3(b), 3(c) or 3(d), or if the Executive terminates his
employment for Good Reason pursuant to Section 3(e), then:

(a) Severance Payment. The Company shall pay to the Executive as
severance pay a lump sum, in cash, in full on the fifth day following the Date
of Termination an amount equal to (i) the Executives highest annual base
salary in effect during the 12-month period immediately preceding the Date of
Termination, and (ii) a lump sum payment of the Executives incentive
compensation bonus that would otherwise be payable to Executive under the
Companys Bonus Plan then in effect for the year in which the Date of
Termination occurred assuming one hundred percent (100%) satisfaction of all
performance goals established under such Bonus Plan for the Executive,
multiplied by 2.0. The foregoing payment shall be in addition to any payments
or other compensation that would otherwise be payable to executives under any
other then existing Severance Plan of the Company. All payments hereunder
shall be made net of withholdings required by applicable federal, state or
local laws.

(b) Stock Options. All stock options not currently exercisable held by
the Executive will accelerate and become exercisable as of the Date of
Termination.

(c) Restricted Stock. All restrictions on any restricted stock, including
without limitation any vesting requirements on any unvested stock, held by the
Executive as of the Date of Termination shall be removed.

(d) Continuation of Benefits. The Company shall continue for a period of
one (1) year from the Date of Termination to provide the following benefits to
the Executive on the same terms as provided to the Executive on the Date of
Termination:

(i) Participation in the Companys medical, dental and vision plans;

(ii) Long-term disability insurance; and

(iii) Life Insurance.

Notwithstanding the foregoing, any benefits payable under this subsection 4(d)
shall terminate at such time as the Executive becomes eligible for similar
benefits from any subsequent employer; provided, however that at the end of the
period of coverage hereinabove provided for, the Executive shall have the
option to have assigned to the Executive at no cost and with no apportionment
of prepaid premiums, any assignable insurance owned by the Company and relating
specifically to the Executive.

(e) Limitation. To the extent that any or all of the payments and
benefits provided for in this Agreement constitute parachute payments within
the meaning of Section 280G of the Internal Revenue Code (the Code) and, but
for this Section 4(e), would be subject to the excise tax imposed by Section
4999 of the Code, then the aggregate amount of such payments and benefits shall
be reduced such that the present value thereof (as determined under the Code
and applicable regulations) is equal to 2.99 times the Executives base
amount (as defined in the Code).

The determination of any reduction or increase of any payment or benefits under
this Section 4 pursuant to the foregoing provision shall be made by a
nationally recognized public accounting firm chosen by the Company in good
faith, and such determination shall be conclusive and binding on the Company
and the Executive.

5. No Obligation to Mitigate Damages: No Effect on Other Contractual
Rights.

(a) No Obligation to Mitigate. The Executive shall not be required to
mitigate damages or the amount of any payment provided for under this Agreement
by seeking other employment or otherwise, nor, except as set forth in Section
4(d), shall the amount of any payment provided for under this Agreement be
reduced by any compensation earned by the Executive as the result of employment
by another employer after the Date of Termination, or otherwise.

(b) No Effect on Other Contractual Rights. The provisions of this
Agreement, and any payment provided for hereunder, shall not reduce any amounts
otherwise payable, or in any way diminish the Executives existing rights, or
rights which would accrue solely as a result of the passage of time, under any
Benefit Plan, Incentive Plan or Securities Plan, employment agreement or other
contract, plan or arrangement.

6. Successors and Assigns.

(a) The Company. As used in this Agreement, Company shall mean the
Company as hereinbefore defined and any successor or assignee to its business
and/or assets as aforesaid which assumes the obligations of the Company under
this Agreement or which otherwise becomes bound by all of the terms and
provisions of this Agreement by operation of law. If at any time during the
term of this Agreement the Executive is employed by any corporation a majority
of the voting securities of which is then owned by the Company, such indirect
employment of the Executive by the Company shall not excuse the Company from
performing its obligations under this Agreement as if the Executive were
directly employed by the Company, and the Company agrees that it shall pay or
shall cause such employer to pay any amounts owed to the Executive pursuant to
Section 4 hereof, notwithstanding any such indirect employment relationship.

(b) The Executive. This Agreement shall inure to the benefit of and be
enforceable by the Executives personal and legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive should die while any amounts are still payable to him hereunder, all
such amounts, unless otherwise provided herein, shall be paid in accordance
with the terms of this Agreement to the Executives devisee, legatee, or other
designee or, if there be no such designee, to the Executives estate.

7. Notice. For purposes of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered, one business day after being
sent for overnight delivery by a nationally recognized overnight courier or
