Dover Corporation (“Dover,” the “Company,” “us” or “we”) hereby offers, on the terms (including the Acceptance Priority Levels) and subject to the conditions set forth in the Tender Offer Documents, to purchase for cash, subject to the Tender Cap (as defined below), the Notes set forth in the table on the front cover of this Offer to Purchase (collectively, the “Notes,” and, each, a “Series” of Notes) from each registered holder (each, a “Holder” and collectively, the “Holders”) of such Notes. This Offer to Purchase relates to four separate offers, one for each Series of Notes set forth in the table on the front cover of this Offer to Purchase (each, an “Offer,” and, collectively, the “Offers”). The Offers are open to all registered Holders of the Notes using a “waterfall” methodology under which we will accept Notes in the order of their respective Acceptance Priority Levels, subject to a $225,000,000 cap on the aggregate Total Consideration payable for Notes purchased in the Offers that we will be obligated to pay (the “Tender Cap”). For the avoidance of doubt, the Tender Cap for Notes purchased in the Offers shall exclude the Accrued Coupon Payment. We describe below the operation of this “waterfall” methodology with respect to each series of Notes, which we refer to as the “Acceptance Priority Procedures.” Additionally, we may increase the amount of Notes accepted for payment in the Offer by no more than 2% of the outstanding Notes of the applicable Series, as further described in the Acceptance Priority Procedures set forth below, without amending or extending the Offer, and may also increase or decrease the percentage of the Notes accepted for payment in the Offer (including by more than 2% of the outstanding Notes of the applicable Series) by a press release or other public announcement that is widely disseminated by no later than 9:00 a.m. (New York City time), on the third business day before the scheduled Expiration Date.

The Offers are not conditioned upon the tender of any aggregate minimum principal amount of Notes of any Series (subject to minimum denomination requirements as set forth in “The Offers—Procedures for Tendering Notes—Minimum Tender Denomination”), and none of the Offers is conditioned on the consummation of any of the other Offers. See “The Offers—Conditions to the Offers.”

This Offer to Purchase and related documents do not constitute an offer to buy or sell or the solicitation of an offer to buy or sell any Notes in any jurisdictions or in any circumstances in which such offer or solicitation is unlawful.
