or updated. Publishers continued distribution of FPUs after a notice of supplement, revision or update is included in the Xbox 360 Publisher Guide or made available to Publisher constitutes Publishers agreement to the then-current Xbox 360Publisher Guide as supplemented, revised or updated. Microsoft will specify in each such supplement, revision or update a reasonable effective date of each change if such change is not required to be effective immediately. Only with respect to a Software Title that has passed Pre-Certification prior to the applicable revision or update, Publisher will not be obligated to comply with any changes made to the technical or content requirements for Software Titles in the Xbox 360 Publisher Guide, except in circumstances where such change is deemed by Microsoft to be vitally important to the success of the Xbox 360 platform (e.g. changes due to piracy, technical failure) or will not add significant expense to the Software Titles development. In addition, changes made in Branding Specifications or other Marketing Materials requirements will be effective as to a Software Title that has passed Certification only on a going forward basis (i.e., only to such Marketing Materials and/or FPUs as are manufactured after Microsoft notifies Publisher of the change). Notwithstanding the foregoing, Publisher shall comply with such changes to the Xbox 360 Publisher Guide related to Branding Specifications or other Marketing Materials requirements retroactively if Microsoft agrees to pay for Publishers direct, out-of-pocket expensesnecessarily incurred as a result of its retrospective compliance with the change.
