Exhibit 10.27

SCHLUMBERGER LIMITED
(the “Company”)

Addendum to

Restricted Stock Unit Award Agreements

Performance Share Unit Agreements

Incentive Stock Option Agreements

Non-qualified Stock Option Agreements

Issued Prior to July 19, 2017

The Compensation Committee of the Board of Directors of Schlumberger Limited
(“the Company”) approved “net settlement”, sometimes referred to as “net
exercise”, which permits employees to pay the exercise price of stock options
with no cash out-of-pocket and no open market sale of shares.  The Company
withholds enough exercised shares to cover the full exercise price of the stock
options and can also cover taxes due on the exercise. Employees receive only the
net number of shares. Incentive Stock Options (“ISOs”) granted prior to July 19,
2017, do not qualify for net settlement.

The following supplemental provisions give effect to net settlement as approved
by the Committee and apply, effective as of July 19, 2017, to the following
stock incentive plans of the Company (all as amended and restated as of July 19,
2017, the “Plans”):

 

•

the 1998 Stock Option Plan;

 

•

the 2001 Stock Option Plan;

 

•

the 2005 Stock Incentive Plan;

 

•

the 2008 Stock Incentive Plan;

 

•

the 2010 Omnibus Stock Incentive Plan;

 

•

the 2013 Omnibus Stock Incentive Plan; and

 

•

the 2017 Omnibus Stock Incentive Plan.

The supplemental provisions also apply to any employee’s Restricted Stock Unit
Award Agreement, Performance Share Unit Agreement, Incentive Stock Option
Agreement, and Non-Qualified Stock Option Agreement (the “Award
Agreements”).  As a result, any stock options, restricted stock units and
performance share units you hold that were issued under the Plans are subject to
the supplemental conditions.

All capitalized terms that are not defined in this Addendum have the meaning set
forth in the applicable Plans and the Award Agreements.  In the event there is a
conflict between provisions in the Award Agreements and these supplemental
provisions, these supplemental provisions will apply.

6.Tax and Social Insurance Withholding

(a)Regardless of any action the Company takes with respect to any or all income
tax (including foreign, federal, state and local taxes), social insurance,
payroll tax, payment on account or other tax-related items related to Employee’s
participation in the Plan and legally applicable to him or her (“Tax-Related
Items”), Employee acknowledges that the ultimate liability for all Tax-Related
Items legally due by Employee is and remains his or her responsibility and may
exceed the amount actually withheld by the Company.  Employee further
acknowledges that the Company (i) makes no representations or undertakings
regarding the treatment of any Tax-Related Items in connection with any aspect
of the Restricted Stock Units, including the grant of the Restricted Stock
Units, the vesting of the Restricted Stock Units, the conversion of the
Restricted Stock Units into shares of Common Stock or the receipt of any
equivalent cash payment, the subsequent sale of any shares of Common Stock
acquired at vesting, and (ii) does not commit to structure the terms of the
grant or any aspect of the Restricted Stock Units to reduce or eliminate
Employee’s liability for the Tax-Related Items.

(b)Prior to any relevant taxable or tax withholding event (“Tax Date”), as
applicable, Employee will pay or make adequate arrangements satisfactory to the
Company to satisfy all Tax-Related Items.  In this regard, Employee authorizes
the Company or its agents, at its discretion, to satisfy the obligations with
regard to all Tax-Related Items by one or both of the following:  (i) accept a
cash payment in U.S. dollars in the amount of the Tax-Related Items or (ii)
withhold whole shares of Common Stock which would otherwise be delivered to
Employee having an aggregate Fair Market Value, determined as of the Tax Date,
or withhold an amount of cash from Employee’s wages or other cash compensation
which would otherwise be payable to Employee by the Company or from any
equivalent cash payment received upon vesting of the Restricted Stock Units,
equal to the amount necessary to satisfy any such obligation.  

(c)The Company shall withhold or account for Tax-Related Items by considering
applicable minimum statutory withholding rates, unless Employee elects, pursuant
to the Company’s prescribed procedures as in effect from time to time, to have
withholding for Tax-Related Items based on the maximum withholding rate
applicable to Employee.  If the obligation for Tax-Related Items is satisfied by
withholding in shares of Common Stock, for tax purposes, Employee is deemed to
have been issued the full number of shares of Common Stock due to him or her at
vesting, notwithstanding that a number of shares of Common Stock are held back
solely for the purpose of paying the Tax-Related Items due as a result of any
aspect of Employee’s participation in the Plan.  Finally, Employee shall pay to
the Company any amount of Tax-Related Items that the Company may be required to
withhold as a result of Employee’s participation in the Plan that cannot be
satisfied by the means previously described.  The Company may refuse to issue
shares of Common Stock to the Employee if Employee fails to comply with his or
her obligations in connection with the Tax-Related Items as described herein.
