estimates of potential cost savings and expenses) reflected in the Materials have been prepared by the Company or are derived from such budgets, projections, estimates, financial analyses, reports and other information or from other sources,
which involve numerous and significant subjective determinations made by management of the Company (“Management”) and/or which Management has reviewed and found reasonable. Any budgets, projections and estimates contained in the Materials may
or may not be achieved and differences between projected results and those actually achieved may be material. Lincoln has relied upon representations made by the Company that any budgets, projections or estimates contained herein have been
reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of Management (or, with respect to information obtained from public sources, represent reasonable estimates), and Lincoln expresses no
opinion with respect to such budgets, projections, or estimates or the assumptions on which they are based. Lincoln has assumed and relied upon the accuracy and completeness of the financial and other information provided to, discussed with or
reviewed by it without (and without assuming responsibility for) independent verification of such information, makes no representation or warranty (express or implied) in respect of the accuracy or completeness of such information and has
further relied upon the assurances of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. In addition, Lincoln has relied upon and assumed, without independent
verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows, or prospects of the Company or any other participant in the Transaction since the respective dates of the
most recent information, financial or otherwise, provided to, discussed with or reviewed by Lincoln that would be material to its analyses, and that the final forms of any draft documents reviewed by Lincoln will not differ in any material
respect from such draft documents. The Materials do not constitute a commitment by Lincoln or any of its affiliates to underwrite, subscribe for or place any securities, to extend or arrange credit, or to provide any other services. Lincoln
