Re: EMPLOYMENT TERMS

Dear Bill:
Digital Realty Trust, Inc. (the “REIT”) and DLR LLC (the “Employer”, and
together with the REIT, the “Company”) are pleased to continue your employment
with the REIT and the Employer on the terms and conditions set forth in this
letter (this “Agreement”), effective as of July 2, 2018 (the “Effective Date”).
This Agreement replaces and supersedes in its entirety that certain employment
letter, by and between you and the Company, dated as of November 23, 2014 (the
“Prior Agreement”).
1.TERM. Subject to the provisions for earlier termination hereinafter provided,
your employment hereunder shall be for a term (the “Term”) commencing on the
Effective Date and ending on the third (3rd) anniversary of the Effective Date
(the “Initial Termination Date”). If not previously terminated, the Term shall
automatically be extended for one additional year on the Initial Termination
Date unless either you or the Company elect not to so extend the Term by
notifying the other party, in writing, of such election not less than sixty (60)
days prior to the Initial Termination Date.
2.    POSITION, DUTIES AND RESPONSIBILITIES. During the Term, the Company will
employ you, and you agree to be employed by the Company, as Chief Executive
Officer of the REIT and the Employer. In the capacity of Chief Executive
Officer, you will have such duties and responsibilities as are normally
associated with such position and will devote your full business time and
attention to serving the Company in such position. Your duties may be changed
from time to time by the Company, consistent with your position. You will report
to the Board of Directors of the REIT (the “Board”), and will work full-time at
our principal offices located in San Francisco, California (or such other
location in the San Francisco greater metropolitan area as the Company may
utilize as its principal offices), except for travel to other locations as may
be necessary to fulfill your responsibilities. At the Company’s request, you
will serve the Company and/or its subsidiaries and affiliates in other offices
and capacities in addition

1

--------------------------------------------------------------------------------

to the foregoing. In the event that you serve in any one or more of such
additional capacities, your compensation will not be increased beyond that
specified in this Agreement. In addition, in the event your service in one or
more of such additional capacities is terminated, your compensation, as
specified in this Agreement, will not be diminished or reduced in any manner as
a result of such termination for so long as you otherwise remain employed under
the terms of this Agreement.
3.    BASE COMPENSATION. During the Term, the Company will pay you a base salary
of $1,000,000 per year, less payroll deductions and all required withholdings,
payable in accordance with the Company’s normal payroll practices and prorated
for any partial month of employment. Your annual base salary may be increased,
but not decreased, by the Compensation Committee of the Board (the “Compensation
Committee”) in its discretion pursuant to the Company’s policies as in effect
from time to time, and such increased amount thereafter will be your base salary
per year for purposes of this Agreement.
4.    ANNUAL BONUS. In addition to the base salary set forth above, during the
Term, you will be eligible to participate in the Company’s incentive bonus plan
applicable to similarly situated executives of the Company. The amount of your
annual bonus will be based on the attainment of performance criteria established
and evaluated by the Company in accordance with the terms of such bonus plan as
in effect from time to time, provided that, subject to the terms of such bonus
plan and attainment of performance criteria established by the Company, your
target and maximum annual bonus shall be one hundred fifty percent (150%) and
three hundred percent (300%), respectively, of your base salary for such year.
Any annual bonus that becomes payable to you is intended to satisfy the
short-term deferral exemption under Treasury Regulation Section 1.409A-1(b)(4)
and shall be made not later than the last day of the applicable two and one-half
(2 ½) month “short-term deferral period” with respect to such annual bonus,
within the meaning of Treasury Regulation Section 1.409A-1(b)(4).
5.    BENEFITS AND FLEXIBLE PAID TIME-OFF. During the Term, you will be eligible
to participate in all incentive, savings and retirement plans, practices,
policies and programs maintained or sponsored by the Company from time to time
which are applicable to other similarly situated executives of the Company,
subject to the terms and conditions thereof. During the Term, you will also be
eligible for standard benefits, such as medical insurance, flexible paid
time-off and holidays to the extent applicable generally to other similarly
situated executives of the Company, subject to the terms and conditions of the
applicable Company plans or policies.

period during which you are providing such services to the Company in accordance

Officer or the Board and (ii) litigation support and senior client relationship
management services to the Company. Such consulting agreement shall (w) be for a
term of forty-eight (48) months, or such longer term that ends immediately after
the last vesting date to occur of any Company equity-based award held by you as

5

--------------------------------------------------------------------------------

protective of the Company than those set forth in Section 8 of this Agreement.
Such consulting agreement and the consulting relationship established thereby
may not be terminated by either party during the term of such consulting
agreement, except by the Company for “cause” (defined in a manner substantially
similar to, and no more expansive in scope than, Cause (as defined below)), by
you for any reason or by mutual agreement of the Company and you. In the event
that the consulting agreement and the consulting relationship established
thereby are terminated (i) by you for any reason or (ii) by the Company for
“cause,” any outstanding awards that are unvested at the time of such
termination shall be forfeited without payment of any consideration therefor. In
the event the consulting agreement and the consulting relationship established
thereby are terminated by mutual agreement, the treatment of any outstanding
awards held by you upon such termination shall be mutually determined by you and
the Company at the time of such termination. With respect to your Retirement,
you also agree that any post-termination covenants in this Agreement, your
Proprietary Information and Inventions Assignment Agreement and your Employee
Confidentiality and Covenant Agreement with the Company shall commence upon the
expiration or termination of the consulting period (and, for the avoidance of
doubt, not upon the termination of your employment). In the event that the
consulting agreement and the relationship established thereby are terminated by
you for any reason or by the Company for “cause,” in either case, you shall
thereupon tender your resignation from the Board and all directorships then held
with any member of the Digital Group (as defined below), which resignation may
be accepted by the Board in its sole discretion, and you agree that, in the
event your resignation is accepted by the Board, you shall take all actions
reasonably requested by the Company to effectuate the foregoing.
(e)    Expiration; Non-renewal. Notwithstanding anything contained herein, in no
event shall the expiration of the Term set forth in Section 1 above or the
Company’s election not to renew or extend the Term or your employment with the
Company constitute a termination of your employment by the Company without
Cause.
(f)    Termination of Offices and Directorships. Upon a termination of your
employment for any reason, except to the extent otherwise determined by the
Board in its sole discretion, you shall be deemed to have resigned from all
offices, directorships and other employment positions, if any, then held with
the Company or any member of the Digital Group, and you agree that you shall
take all actions reasonably requested by the Company to effectuate the
foregoing.
(g)    Potential Six-Month Delay. Notwithstanding anything to the contrary in
this Agreement, no compensation or benefits, including without limitation any
termination payments or benefits payable under this Section 6, shall be paid to
you prior to the expiration of the six (6)-month period following your
“separation from service” from the Company (within the meaning of Section
409A(a)(2)(A)(i) of the Internal Revenue Code of 1986, as amended (the

6

--------------------------------------------------------------------------------

“Code”)) to the extent that the Company determines that paying such amounts at
the time or times indicated in this Agreement would be a prohibited distribution
under Section 409A(a)(2)(B)(i) of the Code. If the payment of any such amounts
is delayed as a result of the previous sentence, then on the first business day
following the end of such six (6)-month period (or such earlier date upon which
such amount can be paid under Section 409A of the Code without resulting in a
prohibited distribution, including as a result of your death), the Company shall
pay you a lump-sum amount equal to the cumulative amount that would have
otherwise been payable to you during such six (6)-month period, plus interest
thereon from the Termination Date through the payment date at a rate equal to
the then-current “applicable Federal rate” determined under Section
7872(f)(2)(A) of the Code.
(h)    Release; Compliance with Covenants. Notwithstanding anything contained
herein, your right to receive the payments and benefits set forth in this
Section 6 is conditioned on and subject to (i) your execution within twenty-one
(21) days (or, to the extent required by applicable law, forty-five (45) days)
following the Termination Date and non-revocation within seven (7) days
thereafter of a general release of claims against the Digital Group (as defined
below), in a form reasonably acceptable to the Company, (ii) your continued
compliance with the restrictive covenants set forth in Section 8 of this
Agreement and any similar covenants set forth in any other agreement between you
and the Company, and (iii) your compliance with Section 6(f) above.
(i)    Definitions. For purposes of this Agreement:
(A)    “Cause” shall mean (1) your willful and continued failure to
substantially perform your duties with the Company (other than any such failure
resulting from your incapacity due to physical or mental illness), after a
written demand for substantial performance is delivered to you by the Company,
which demand specifically identifies the manner in which the Company believes
that you have not substantially performed your duties and which failure is not
cured within thirty (30) days of receiving such notice; (2) your willful
commission of an act of fraud or dishonesty resulting in economic or financial
injury to the Company or its subsidiaries or affiliates; (3) your conviction of,
or entry by you of a guilty or no contest plea to, the commission of a felony or
a crime involving moral turpitude; (4) a willful breach by you of any fiduciary
duty owed to the Company which results in economic or other injury to the
Company or its subsidiaries or affiliates; (5) your willful and gross misconduct
in the performance of your duties hereunder that results in economic or other
injury to the Company or its subsidiaries or affiliates and which misconduct is
not cured within thirty (30) days after written notification is delivered to you
by the Company that specifically identifies any such misconduct; (6) your
willful and material breach of your covenants set forth in Section 8 below; or
(7) a material breach by you of any of your other obligations

7

--------------------------------------------------------------------------------

under this Agreement after written notice is delivered to you by the Company
which specifically identifies such breach. For purposes of this provision, no
act or failure to act on your part will be considered “willful” unless it is
done, or omitted to be done, by you in bad faith or without reasonable belief
that your action or omission was in the best interests of the Company.
Notwithstanding the foregoing, in the event you incur a “separation from
service” by reason of a termination of your employment by the Company (other
than by reason of your death or Disability or pursuant to clause (3) of this
paragraph) on or within one year after a Change in Control or within the six
month period immediately preceding a Change in Control in connection with such
Change in Control, it shall be presumed for purposes of this Agreement that such
termination was effected by the Company other than for Cause unless the contrary
is established by the Company. In addition, notwithstanding the foregoing, your
employment will not be deemed to have been terminated for Cause unless and until
there shall have been delivered to you a copy of a resolution duly adopted by
the affirmative vote of a majority the Board, including a majority of the
independent directors, at a meeting of the Board called and held for such
purpose (after reasonable notice is provided to you and you are given an
opportunity to be heard before the Board), finding that, in the good faith
opinion of the Board, sufficient Cause exists to terminate your employment;
provided, that you shall not participate in the deliberations regarding such
resolution, vote on such resolution, nor shall you be counted in determining a
majority of the Board.
(B)    “Disability” shall mean a disability that qualifies or, had you been a
participant, would qualify you to receive long-term disability payments under
the Company’s group long-term disability insurance plan or program, as it may be
amended from time to time.
(C)    “Good Reason” shall mean the occurrence of any one or more of the
following events without your prior written consent, unless the Company corrects
the circumstances constituting Good Reason (provided such circumstances are
capable of correction) prior to the Termination Date: (1) the Company’s
assignment to you of any duties materially inconsistent with your position
(including status, offices, titles and reporting requirements), authority,
duties or responsibilities as contemplated by Section 2 hereof, or any other
action by the Company which results in a material diminution in such position,
authority, duties or responsibilities, excluding for this purpose an isolated,
insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company; (2) the Company’s material reduction of your annual
base salary or bonus opportunity, each as in effect on the date hereof or as the
same may be increased from time to time; (3) the relocation of the Company’s
offices at which you are principally employed (the “Principal Location”) to a
location more than forty-five (45) miles from such location, or the Company’s

8

--------------------------------------------------------------------------------

than forty-five (45) miles from the Principal Location, except for required
travel on Company business; or (4) a material breach by the Company of Section
15 of this Agreement. Notwithstanding the foregoing, you will not be deemed to
have resigned for Good Reason unless (x) you provide the Company with written
notice of the circumstances constituting Good Reason within thirty (30) days
after the initial occurrence or existence of such circumstances, (y) the Company
fails to correct the circumstance so identified within thirty (30) days after
the receipt of such notice (if capable of correction), and (z) the Termination
Date occurs no later than ninety (90) days after the initial occurrence of the
event constituting Good Reason.
(D)    “Prior Year Bonus” shall mean, for any Termination Date that occurs
between January 1 of any fiscal year and the date that annual bonuses are paid
by the Company for the immediately preceding year (the “Prior Year”), your
target annual bonus (without giving effect to any reduction which constitutes
Good Reason) for such Prior Year, unless the Compensation Committee has
determined your bonus for such Prior Year, in which case the Prior Year Bonus
shall be the bonus determined by the Compensation Committee, if any. The Prior
Year Bonus, if any, shall be in lieu of your annual bonus for the Prior Year.
There will be no Prior Year Bonus in connection with any Termination Date that
occurs on or after the date the Company pays annual bonuses for the Prior Year
through the end of the year in which the Termination Date occurs.
(E)    “Retirement” shall mean your voluntary retirement from your employment
with the Company at a time when (i) you have attained at least fifty-five (55)
years of age, (ii) you have completed at least ten (10) Years of Service (as
defined below) with the Company, and (iii) your combined age plus Years of
Service equals at least seventy (70), provided that you have provided the
Company with at least twelve (12) months’ advance written notice of your
retirement (or such other shorter minimum advance written notice that is
acceptable to the Board in its sole discretion), which notice shall be provided
no earlier than such time as you have satisfied the conditions set forth in
clauses (i), (ii) and (iii) above (the “Notice Period”). For purposes of this
Agreement, (x) if, during the Notice Period, your employment is terminated by
the Company without Cause, such termination of employment shall be deemed to
have occurred by reason of your Retirement for purposes of this Agreement (and,
for avoidance of doubt, you will not be entitled to any payments or benefits
under Section 6(a) hereof), (y) if, during the Notice Period, your employment is
terminated for any other reason, such termination of employment shall not be
deemed to have occurred by reason of your Retirement for purposes of this
Agreement, and (z) provided that you continue in employment with the Company
through the Notice Period, your employment shall automatically terminate upon
the termination date set forth in such notice (or such other date accepted by
the Board).

9

--------------------------------------------------------------------------------

(F)    “Stub Year Bonus” shall mean the product obtained by multiplying (x) your
target annual bonus for the fiscal year in which the Termination Date occurs
(without giving effect to any reduction which constitutes Good Reason)
multiplied by (y) a fraction, the numerator of which is the number of calendar
days that have elapsed in the then current fiscal year through the Termination
Date and the denominator of which is 365; provided, however, that in the case of
your Retirement, “Stub Year Bonus” shall mean the product obtained by
multiplying (A) the average annual bonus earned by you for the three (3) Company
fiscal years immediately preceding the Company fiscal year in which your
Retirement occurs multiplied by (B) a fraction, the numerator of which is the
number of calendar days that have elapsed in the then current fiscal year
through the date of your Retirement and the denominator of which is 365.
(G)    “Years of Service” means the aggregate period of time, expressed as a
number of whole years and fractions thereof, during which you were an employee
of the Company in paid status.
7.    LIMITATION ON PAYMENTS.
(a)    Best Pay Cap. Notwithstanding any other provision of this Agreement, in
the event that any payment or benefit received or to be received by you
(including any payment or benefit received in connection with a termination of
your employment, whether pursuant to the terms of this Agreement or any other
plan, arrangement or agreement) (all such payments and benefits, including the
payments and benefits under Section 6 of this Agreement, the “Total Payments”)
would be subject (in whole or part) to the excise tax imposed under Section 4999
of the Code (the “Excise Tax”), then, after taking into account any reduction in
the Total Payments provided by reason of Section 280G of the Code in such other
plan, arrangement or agreement, your remaining Total Payments shall be reduced
to the extent necessary so that no portion of the Total Payments is subject to
the Excise Tax, but only if (i) the net amount of such Total Payments, as so
reduced (and after subtracting the net amount of federal, state and local income
taxes applicable to such reduced Total Payments and after taking into account
the phase out of itemized deductions and personal exemptions attributable to
such reduced Total Payments) is greater than or equal to (ii) the net amount of
such Total Payments without such reduction (but after subtracting the net amount
of federal, state and local income taxes on such Total Payments and the amount
of Excise Tax to which you would be subject in respect of such unreduced Total
Payments and after taking into account the phase out of itemized deductions and
personal exemptions attributable to such unreduced Total Payments). The
reduction undertaken pursuant to this Section 7(a) shall be accomplished first
by reducing or eliminating any cash payments subject to Section 409A of the Code
as deferred compensation (with payments to be made furthest in the future being
reduced first), then by reducing or eliminating cash payments that are not
subject to Section 409A of the Code, then by reducing payments attributable to
equity-based

10

--------------------------------------------------------------------------------

compensation (or the accelerated vesting thereof) subject to Section 409A of the
Code as deferred compensation (with payments to be made furthest in the future
being reduced first), and finally by reducing payments attributable to
equity-based compensation (or the accelerated vesting thereof) that is not
subject to Section 409A of the Code.
(b)    Certain Exclusions. For purposes of determining whether and the extent to
which the Total Payments will be subject to the Excise Tax, (i) no portion of
the Total Payments, the receipt or retention of which you have waived at such
time and in such manner so as not to constitute a “payment” within the meaning
of Section 280G(b) of the Code, will be taken into account; (ii) no portion of
the Total Payments will be taken into account which, in the written opinion of
an independent, nationally recognized accounting firm (the “Independent
Advisors”) selected by the Company, does not constitute a “parachute payment”
within the meaning of Section 280G(b)(2) of the Code (including by reason of
Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no
portion of such Total Payments will be taken into account which, in the opinion
of Independent Advisors, constitutes reasonable compensation for services
actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in
excess of the “base amount” (as defined in Section 280G(b)(3) of the Code)
allocable to such reasonable compensation; and (iii) the value of any non-cash
benefit or any deferred payment or benefit included in the Total Payments shall
be determined by the Independent Advisors in accordance with the principles of
Sections 280G(d)(3) and (4) of the Code.
8.    RESTRICTIVE COVENANTS.
(a)    As a condition of your employment with the Company, you agree that during
the Term and thereafter, you will not directly or indirectly disclose or
appropriate to your own use, or the use of any third party, any trade secret or
confidential information concerning the REIT, the Operating Partnership, the
Employer or their respective subsidiaries or affiliates (collectively, the
“Digital Group”) or their businesses, whether or not developed by you, except as
it is required in connection with your services rendered for the Company. You
further agree that, upon termination of your employment, you will not receive or
remove from the files or offices of the Digital Group any originals or copies of
documents or other materials (physical, electronic or otherwise) of the Digital
Group, and that you will return any such documents or materials (physical,
electronic or otherwise) otherwise in your possession. You further agree that,
upon termination of your employment, you will maintain in strict confidence and
not disclose the projects in which any member of the Digital Group is involved
or contemplating.
(b)    You further agree that during the Term, you shall not, unless agreed to
in writing by the Company, engage in Competition (as defined below). For
purposes of this Agreement, “Competition” shall mean participating, directly or
indirectly, including through any investment fund, in the acquisition or
disposition of any interests in, the taking of leasehold

11

interests in, the lending of funds to, or the management of, including as a
principal, partner, stockholder or manager of, or advisor or consultant to, any
partnership, corporation, limited liability company or any other entity,

“Technology Real Estate” shall mean commercial real estate land and buildings
that are used principally (i) to provide infrastructure required by companies in
the data, voice and wireless communications industry; (ii) to provide the
physical environment required for businesses in the disaster recovery, IT
outsourcing and collocation industries, or (iii) as data centers or colocation

stockholder or manager of the Company or any of its subsidiaries or affiliates,
or (y) (i) any investments in publicly-traded companies or (ii) any passive
investments in investment funds, in each case, in which you own less than a five
percent (5%) beneficial interest in such publicly-traded company or investment
fund, as applicable, and have no active management role.
(c)    You further agree that during the Term and continuing through the second
(2nd) anniversary of the date of termination of your employment, you will not
directly or indirectly solicit, induce, or encourage any then current employee
of any member of the Digital Group to terminate their employment with such
member of the Digital Group.
(d)    You further agree that during the Term and thereafter, you will not
utilize any trade secret or confidential information concerning the Digital

encourage any consultant, agent, customer, vendor, or other parties doing
business with any member of the Digital Group to terminate their agency or other
relationship with such member of the Digital Group or to transfer their business
from the such member or the Digital Group and you will not initiate discussion
with any such person for any such purpose or authorize or knowingly cooperate

(b), (c) or (d) above, that monetary damages for such breach would not be
readily calculable, and that the Company would not have an adequate remedy at
law therefor, you acknowledge, consent and agree that in the event of such
breach, or the threat thereof, the Company shall be entitled, in addition to any
other legal remedies and damages available, to specific performance thereof and
to temporary and permanent injunctive relief (without the necessity of posting a
bond) to restrain the violation or threatened violation of such obligations by
you.
9.    CODE SECTION 409A.

12

--------------------------------------------------------------------------------

(a)    To the extent applicable, this Agreement shall be interpreted and applied
consistent and in accordance with Section 409A of the Code and Department of
Treasury regulations and other interpretive guidance issued thereunder.
Notwithstanding any provision of this Agreement to the contrary, if at any time
you and the Company mutually determine that any compensation or benefits payable
under this Agreement may not be compliant with or exempt from Section 409A of
the Code and related Department of Treasury guidance, the parties shall work
together to adopt such amendments to this Agreement or adopt other policies and
procedures (including amendments, policies and procedures with retroactive
effect), or take such other actions, as the parties determine are necessary or
appropriate to (i) exempt such compensation and benefits from Section 409A of
the Code and/or preserve the intended tax treatment of such compensation and
benefits, or (ii) comply with the requirements of Section 409A of the Code and
related Department of Treasury guidance; provided, however, that this Section
9(a) shall not create any obligation on the part of the Company to adopt any
such amendment, policy or procedure or take any such other action.
(b)    To the extent permitted under Section 409A of the Code, any separate
payment or benefit under this Agreement or otherwise shall not be deemed
“nonqualified deferred compensation” subject to Section 409A of the Code and
Section 6(g) hereof to the extent provided in the exceptions in Treasury
Regulation Section 1.409A-1(b)(4), Section 1.409A-1(b)(9) or any other
applicable exception or provision of Section 409A of the Code.
(c)    To the extent that compensation or benefits payable under Section 6 of
this Agreement (i) constitute “nonqualified deferred compensation” within the
meaning of Section 409A of the Code or (ii) are intended to be exempt from
Section 409A of the Code under Treasury Regulation Section 1.409A-1(b)(9)(iii),
and are designated under this Agreement as payable upon (or within a specified
time following) your termination of employment, such compensation or benefits
shall, subject to Section 6(g) hereof, be payable only upon (or, as applicable,
within the specified time following) your “separation from service” from the
Company (within the meaning of Section 409A(a)(2)(A)(i) of the Code).
(d)    To the extent that any payments or reimbursements provided to you under
this Agreement, including, without limitation under Section 18 hereof, are
deemed to constitute compensation to which Treasury Regulation Section
1.409A-3(i)(1)(iv) would apply, such amounts shall be paid or reimbursed to you
reasonably promptly, but not later than December 31 of the year following the
year in which the expense was incurred. The amount of any such payments eligible
for reimbursement in one year shall not affect the payments or expenses that are
eligible for payment or reimbursement in any other taxable year, and your right
to such payments or reimbursement shall not be subject to liquidation or
exchange for any other benefit.

Handbook, Code of Business Conduct and Ethics, Insider Trading Policy, and as

consultancy is shared among the Company and/or its subsidiaries and affiliates,
the payment or provision to you by the Company of any remuneration, benefits or
other financial obligations pursuant to this Agreement may be allocated to the
Company and, as applicable, its subsidiaries and/or affiliates in accordance
with an employee sharing or expense allocation agreement entered into by such
parties.
12.    WITHHOLDING. The Company may withhold from any amounts payable under this
Agreement such Federal, state, local or foreign taxes as shall be required to be

13.    ARBITRATION. Except as set forth in Section 8(e) above, any disagreement,
dispute, controversy or claim arising out of or relating to your employment with
the Company, including those arising out of or relating to this Agreement, shall
be settled by final and binding arbitration before a single neutral arbitrator.
Arbitration shall be administered by JAMS in San Francisco, California in
accordance with the then existing JAMS Employment Arbitration Rules and
Procedures, the current version of which is available at
https://www.jamsadr.com/rules-employment-arbitration/. Except as provided
herein, the Federal Arbitration Act shall govern the interpretation, enforcement
and all proceedings. The arbitrator shall apply the substantive law (and the law
of remedies, if applicable) of the state of California, or federal law, or both,
as applicable, and the arbitrator is without jurisdiction to apply any different
substantive law. The arbitrator shall have the authority to entertain a motion
to dismiss and/or a motion for summary judgment by any party and shall apply the
standards governing such motions under the Federal Rules of Civil Procedure.
Judgment upon the award may be entered in any court having jurisdiction thereof.
Each party will pay the fees for his, her or its own attorneys, subject to any
fee-shifting statutes that govern the claims at issue in arbitration. However,
in all cases where required by law, the Company will pay the arbitrator’s and
the arbitration fees. If under applicable law the Company is not required to pay
all of the arbitrator’s and/or the arbitration fees, such fee(s) will be
apportioned between the parties by the arbitrator in accordance with said
applicable law, and any disputes in that regard will be resolved by the
arbitrator.

your Employee Confidentiality and Covenant Agreement with the Company and your

and legal representatives.

direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume and
agree to perform this Agreement in the same manner and to the same extent that
the Company would be required to perform it if no such succession had taken
place.
