Addendum to Consultancy Contract

between

Groupon Europe GmbH

- hereinafter “Company” -

and

Oliver Samwer

- hereinafter “Consultant” -.

Company and the Consultant are hereinafter referred to as “Parties”, each a “Party”.

Preamble

(1) The Parties entered into a consultancy contract (Beratervertrag) as of 19 May 2010 (“Consultancy Contract”).

(2) The Parties intend to amend the Consultancy Contract in order to stipulate a contractual penalty in case of a breach of the Consultancy Contract.

Now, therefore, the Parties agree to amend the Consultancy Contract as follows

§ 1 Contractual Penalty

(1) For each breach of the Consultant’s duties under Section 1 para (2) of the Consultancy Contract (except due to death or inability to work by reason of illness or permanent disability), that is continued despite a written warning sent by the Company to the Consultant (“Warning”) and after giving the Consultant a period of 14 days to cure any alleged breach (“Curing Period”), the Consultant shall pay a contractual penalty of US$ 25,000 (in words: Dollar twenty five thousand) to the Company for each calendar day (after the Curing Period) as long as the violation is continued (“Contractual Penalty”). After having received a Warning the Consultant shall notify the Company in writing if he cured the breached (“Cure Notification”). If the Consultant has duly given a Cure Notification the breach shall be deemed cured and the Company shall be pre-cluded

1

from claiming any Contractual Penalty with respect to such cured breach unless the Company has given a written notice of objection to the Cure Notification within five days after receipt of the Cure Notification describing in reasonable detail the reason why the Company believes the breach was not. If a breach was cured in accordance with the aforesaid sentences, this § 1 shall apply again to any new breach.

(2) The Contractual Penalty shall in any case be credited against any damage claims the Company may raise vis-à-vis the Consultant in connection with a breach of the Consultant’s duties under the Consultancy Contract. Nothing contained in this Agreement shall limit or impair any rights or remedies of the Company with respect to any such breach, including, without limitation, any statutory, equitable or common law remedies to which the Company may be entitled.

§ 2 Miscellaneous

(1) This addendum agreement contains the entire agreement between the Parties with respect to the subject matter hereof.

(2) This agreement and/or the Consultancy Agreement may only be amended by written instrument executed by all Parties unless mandatory law requires more stringent form requirements.

(3) This addendum agreement and the Consultancy Agreement shall be subject to the laws of the Federal Republic of Germany, excluding their private international law provisions.

(4) Apart from the above stipulation, the Consultancy Contract remains in full force and effect.
