Conditions to Closing. Completion of the Merger is subject to certain customary conditions, including, adoption of the Merger Agreement by CH2M stockholders, approval of the listing of the shares of Jacobs common stock to be issued in the Merger on the New York Stock Exchange (“NYSE”), receipt of required antitrust approvals and effectiveness of Jacobs’ registration statement on Form S-4 registering the shares to be issued in connection with the Merger.

Representations, Warranties and Covenants. The Merger Agreement contains customary representations, warranties and covenants made by each of Jacobs, CH2M, and Merger Sub. CH2M is required, among other things, not to solicit alternative business combination transactions and, subject to certain exceptions, not to engage in discussions or negotiations regarding an alternative business combination transaction. CH2M is required to convene a special meeting of its stockholders to vote on the adoption of the Merger Agreement.

Board Representation. Prior to the Closing, Jacobs will designate and appoint one director from the CH2M Board of Directors who qualifies as an “independent director” under applicable NYSE rules to the Board of Directors of Jacobs as of immediately after the Effective Time, to serve in such capacity until his or her successor is duly elected or appointed and qualified in accordance with applicable law.

Termination Rights. Both Jacobs and CH2M may terminate the Merger Agreement under certain specified circumstances, including if the Merger is not consummated within nine months of the date of signing, subject to a three month extension under certain circumstances (the “Outside Date”), if the approval of the CH2M stockholders is not obtained, and if CH2M’s Board of Directors makes an adverse recommendation change with respect to the proposed transaction or to enter into a superior acquisition proposal. In certain circumstances in connection with the termination of the Merger Agreement, including if CH2M’s Board of Directors changes or withdraws its recommendation of the Merger to its stockholders or terminates the Merger Agreement to enter into an agreement with respect to a superior proposal, CH2M must pay to Jacobs a termination fee equal to $85,444,783.80. Additionally, in the event that either CH2M or Jacobs terminates the Merger Agreement as a result of the failure by CH2M’s stockholders to adopt the Merger Agreement, CH2M must reimburse Jacobs for its reasonable and documented out-of-pocket expenses in connection with the Merger (in an amount not to exceed $15 million).

The foregoing summary of the Merger Agreement and the transactions contemplated thereby, does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, which is filed as Exhibit 2.1 to this Form 8-K and incorporated herein by reference.

The Merger Agreement and the above description have been included to provide investors and security holders with information regarding the terms of the agreement. They are not intended to provide any other factual information about Jacobs, CH2M or their respective subsidiaries or affiliates or stockholders. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of the Merger Agreement and as of specific dates; were solely for the benefit of the parties to the Merger Agreement; and may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made by each contracting party to the other for the purposes of allocating contractual risk between them that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of Jacobs, CH2M, Merger Sub or any of their respective subsidiaries, affiliates, businesses, or stockholders. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures

by Jacobs or CH2M. Accordingly, investors should read the representations and warranties in the Merger Agreement not in isolation but only in conjunction with the other information about Jacobs or CH2M and their respective subsidiaries that the respective companies include in reports, statements and other filings they make with the SEC.

Modifications to the 2017 CH2M Bonus Plans

Forward-Looking Statements

This communication contains forward-looking statements that are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements include statements regarding our future financial performance, results of operations; benefits of the transaction to stockholders and employees; potential synergies and cost savings resulting from the transaction; the ability of the combined companies to drive growth; other statements regarding the proposed transaction and any other statements that are other than statements of historical fact. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “projects,” “potential,” “continue,” and other similar terminology or the negative of these terms, but their absence does not mean that a particular statement is not forward-looking. Such forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties that may cause actual results to differ materially from those anticipated by the forward-looking statements. These statements are not guarantees of future performance, involve risks, uncertainties and assumptions that are difficult to predict, and are based upon assumptions as to future events that may not prove accurate. For example, if CH2M does not receive the required stockholder approval or the parties fail to satisfy other conditions to closing, the transaction may not be consummated. In any forward-looking statement in which CH2M or Jacobs expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the statement or expectation or belief will result or be achieved or accomplished. The following factors, among others, could cause actual results to differ materially from those described in the forward-looking statements: failure of the CH2M stockholders to approve the proposed transaction; the challenges and costs of closing, integrating, restructuring and achieving anticipated synergies; the ability to retain key employees; and other economic, business, competitive, and/or regulatory factors affecting the businesses of CH2M and Jacobs generally, including those set forth in the filings of CH2M and Jacobs with the SEC, especially in the “Risk Factors” section of CH2M’s Annual Report on Form 10-K for the year ended December 30, 2016 filed with the SEC on March 7, 2017, the “Risk Factors” section of Jacobs’ Annual Report on Form 10-K for the year ended September 30, 2016 filed with the SEC on November 22, 2016, and Jacobs’ Quarterly Reports on Form 10-Q for the quarterly periods ended December 30, 2016 and March 31, 2017, filed with the SEC on February 8, 2017 and May 9, 2017, respectively, and in CH2M’s and Jacobs’ other periodic
