If the Cash Settlement Amount per Option is not specified on the grid above,
Cash Settlement Amount per Option shall be determined based on a straight-line
interpolation between the Unwind Prices or extrapolation from the Unwind Prices
(as the case may be) specified on the grid above.

“Unwind Price” means the arithmetic average of the VWAP Prices for all of the
Measurement Dates during the relevant Measurement Period.

“VWAP Price” for any Scheduled Trading Day means the per Share volume-weighted
average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page
GPI <equity> AQR (or any successor thereto) in respect of the period from 9:30
a.m. to 4:00 p.m. (New York City time) on such Scheduled Trading Day (or if such
volume-weighted average price is unavailable, the market value of one Share on
such Scheduled Trading Day, as determined by Dealer).

Notwithstanding anything to the contrary in this Agreement, if (i) any Scheduled
Trading Day during any Measurement Period is a Disrupted Day (as defined in the
Warrant Confirmation) or (ii) Dealer determines in its commercially reasonable
judgment that on any Scheduled Trading Day during the relevant Measurement
Period an extension of such Measurement Period is reasonably necessary or
appropriate to preserve Dealer’s hedge unwind activity hereunder in light of
existing liquidity conditions or to enable Dealer to effect sales of Shares in
connection with its hedge unwind activity hereunder in a manner that would be in
compliance with applicable legal, regulatory or self-regulatory requirements, or
with related policies and procedures applicable to Dealer, then the VWAP Price
for such Scheduled Trading Day(s) shall be the volume-weighted average price per
Share on such Scheduled Trading Day on the Exchange, as determined by the Dealer
based on such sources as it deems appropriate using a volume-weighted
methodology, for the portion of such Scheduled Trading Day for which Dealer
determines there is no Market Disruption Event and the number of Measurement
Dates and the Unwind Price for the relevant Measurement Period shall be adjusted
by Dealer to account for such disruption and/or extension.
