5. Warranty, liability and support

The license carries the following clauses, quoted from the model.
Warranty disclaimer: There is no warranty for The Program. Except when otherwise stated in writing, The Copyright Holder provides The Program `as is', without warranty of any kind, either expressed or implied, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose. The entire risk as to the quality and performance of The Program is with you. Should The Program prove defective, you assume the cost of all necessary servicing, repair, or correction.
Limitation of liability: In no event unless agreed to in writing will The Copyright Holder, or any author named in the files of The Program, or any other party who may distribute and/or modify The Program as permitted below, be liable to you for damages, including any general, special, incidental or consequential damages arising out of any use of The Program or out of inability to use The Program (including, but not limited to, loss of data, data being rendered inaccurate, or losses sustained by anyone as a result of any failure of The Program to operate with any other programs), even if The Copyright Holder or said author or said other party has been advised of the possibility of such damages.
Additional clauses: This license gives conditions under which The Program may be distributed and conditions under which modified versions of The Program may be distributed. Individual files of The Program may bear supplementary and/or superseding conditions on modification of themselves and on the distribution of modified versions of themselves, but *no* file of The Program may bear supplementary or superseding conditions on the distribution of an unmodified copy of the file. A distributor wishing to distribute a complete, unmodified copy of The Program therefore needs to check the conditions only in this license and nowhere else. Activities other than distribution and/or modification of The Program are not covered by this license; they are outside its scope. In particular, the act of running The Program is not restricted.
