If the claims leader has, on his own and the co-insurers' behalf, provided a guarantee or counterguarantee for the assured's liability arising from collision, striking or salvage, he may claim a commission of 1 % of the guarantee amount. If an open guarantee is provided, the commission shall be calculated on the basis of the effective gross liability.
If a co-insurer has been notified that the claims leader has provided a guarantee in accordance with sub-clause 1, the co-insurer may not pay compensation in connection with the liability directly to the assured.
The co-insurer may not set off against the claims leader counterclaims against the assured, unless he has made a special reservation to that effect prior to the provision of security.
