                  (as amended and restated February 28, 2005)

WHEREAS, Juniper Networks, Inc. ("Juniper") acknowledges that Scott Kriens has

WHEREAS, such travel expenses include use of private aircraft for purposes of

WHEREAS, Juniper has determined that the use of private aircraft by Scott Kriens
is reasonable and necessary to properly and efficiently fulfill the critical,
frequent, and often changing demands placed on Scott Kriens in his capacity as
the Chairman, Chief Executive Officer and President of Juniper;

WHEREAS, notwithstanding the benefits derived from and need for use of private
aircraft in the conduct of Juniper business, Juniper has not committed, and does

the lease of corporate aircraft;

WHEREAS, Juniper has partially reimbursed Scott Kriens for substantiated
expenses attributable to such use of private aircraft for Juniper business under
its general expense reimbursement policy;

Kriens and establish a fixed rate for such reimbursement;

IT IS RESOLVED, Juniper will reimburse Scott Kriens for substantiated expenses
attributable to the use of private aircraft in connection with the performance
of services for Juniper as its Chairman, Chief Executive Officer and President,
equal to a fixed rate per flying hour in connection with any such flight (such
amount shall initially be established as $2,000 per hour and shall be subject to
periodic review based on actual ordinary operating costs); provided, however,
that the total reimbursement amount paid to Scott Kriens in connection with any
