VINX Index Information: Adjustment of VINX Benchmark Index due to share distribution in Lundin Petroleum AB (20/10)

The following information is based on public information from Lundin Petroleum
AB (LUPE) (SE0000825820) published on October 20, 2010 and may be subject to
change. 

The Board of Directors of Lundin Petroleum AB has proposed that the
Extraordinary General Meeting (EGM) scheduled for November 4, 2010 resolves on
a distribution of the shares in its partly owned subsidiary Etrion Corporation
(Etrion). The board of Directors propose that one share in LUPE entitles the
shareholder to receive 0.2283 shares in Etrion. 

NASDAQ OMX Global Index Group will act and adjust LUPE in accordance to the
“Rules for the Construction and Maintenance of the NASDAQ OMX and Oslo Børs
All-Share, Benchmark, Tradable and Sector Indexes”, rule 5.1 “Discretionary
adjustments” and 5.7.1 “Direct Inclusion”. 

The discretionary adjustment is that we allow for Etrion's first trading day to
occur on t+4 instead of t+3 as stated in the Direct Inclusion rule. 
The Ex-date has been set to Nov 8, 2010 and listing of the Etrion share is
expected to occur on Nov 12, 2010. A total of 50 805 289 Etrion shares will be
included in VINXB, in accordance with the terms of the distribution. Note that
this event will not trigger a quarterly capping. 

Description of the adjustment:
The start value of Etrion will be determined by the difference between LUPE's
previous day's closing price (t-1) and the first traded price on the Ex-day
(t). That value will then be applied to Etrion and be fixed in the index
calculation (cash component) until the first trading day of Etrion. On its
first trading day, Etrion will start at the fixed price determined at (t) and
then be included at last traded price throughout the day. The Etrion share will
remain an index constituent until the next review is effective Dec 1, 2010.
