RE: Terrex Change Order Proposal

Dear Paul,

Further to discussions between Malcolm Bendall and Joe Dwyer of our office, this letter is to set out a Change Order Proposal pursuant to Clause 4 of the Seismic Services Agreement dated 20 January 2012.

Following on from your request regarding Terrex’s crew standing down, our proposal is as follows:

·

Terrex will safely store its plant and equipment in Tasmania whilst GSLM finalise permitting.

·

Terrex’s Seismic personnel will be demobilised back to Brisbane – once off fee of $5,000

·

Terrex Spatial surveyors will be demobilised – once off fee of $1,000

·

Status will be reviewed at least weekly – GSLM to provide regular updates of permitting progress.

·

Terrex’s crew will be on stand-down awaiting permitting at a reduced fee of the working rate @. $4,100 per day

·

If requested, Terrex can assist GSLM in their attempt to gain prompt permitting so that the seismic program can commence ASAP.  Terrex would provide the services of an experienced Operations Manager to assist GSLM ($1,200 per day plus expenses).

·

When permits are received Terrex Spatial will remobilise (once off fee of $1,000) followed by Terrex Seismic (once off fee of $5,000)

Please note that all of the points above are in additional to those items listed in Schedule B of the Agreement, and are exclusive of GST.

If this Proposal is acceptable to you, can you please acknowledge by arranging signing below and returning a copy to me at your earliest convenience.

Kind regards,

/s/ Matthew Wright
