PGS ASA

Petroleum Geo-Services ASA : Amendment Process Successfully Completed

May 25, 2016: Oslo, Norway, Petroleum Geo-Services ASA ('PGS' or the 'Company')

has received consent from the required lenders of the Revolving Credit Facility

to amend the leverage ratio maintenance covenant. The maintenance covenant,

Total Leverage Ratio ("TLR"), is changed from maximum 4.00:1 to 5.50:1 for the

period up to and including Q1 2017, thereafter tightening the maximum TLR by

0.50:1 in each of the subsequent two quarters, then down to the previous TLR of

3.25:1 in Q4 2017. From Q4 2017 the TLR will be tightened by 0.25:1 each

quarter down to 2:75:1 by Q2 2018. The TLR is, as before, calculated by dividing

the total indebtedness by the adjusted EBITDA for the last four quarters and

reported on a quarterly basis.

Should the Company, at its sole discretion, elect to raise equity in the future,

the amendment allows for the adjusted EBITDA in the TLR calculation to include

cash proceeds received from one equity issue of the Company. Such proceeds would

be included in the TLR calculation for four quarters.

The adjusted EBITDA can also, be adjusted to exclude one-time, non-recurring

restructuring cost, if any, up to $30 million.

The margin structure and dividend restriction are the same as earlier. A consent

fee is payable to consenting banks.

There are no further significant changes or conditions relating to the

amendment. The amendment is subject to completion of documentation.
