Working Groups From time to time, a Joint Committee may establish and delegate duties to sub-committees or directed teams (each, a “Working Group”) on an “as-needed” basis to oversee particular projects or activities (e.g., joint project team, joint finance group, or joint intellectual property group). Each such Working Group shall be constituted and shall operate as the Joint Committee determines; provided, that each Working Group shall have equal representation from each Party, unless otherwise mutually agreed. Working Groups may be established on an ad hoc basis for purposes of a specific project or on such other basis as the Joint Committee may determine. Each Working Group and its activities shall be subject to the oversight, review and approval of, and shall report to, the Joint Committee that formed said Working Group. In no event shall the authority of the Working Group exceed that specified for the Joint Committee that formed the Working Group. All decisions of a Working Group shall be by unanimous agreement. Any disagreement between the designees of AbbVie and Ablynx on a Working Group shall be referred to the Joint Committee that formed the Working Group for resolution.
