You have previously received and reviewed the Offer to Purchase, and you hereby ELECT TO PARTICIPATE IN THE OFFER. You certify that you are a holder of Eligible Options and that you are an Eligible Employee (as both are defined in the Offer to Purchase). You understand that your election to participate in the Offer is voluntary, and by signing this Election Form, you agree to sell certain of your Eligible Options (as indicated in the table below) to Medpace Investors, LLC (“Medpace Investors”). In return for your Eligible Options, you understand that Medpace Investors will pay you a cash payment as indicated below, reduced by any Tax-Related Items, as defined below.

You understand that, upon acceptance by Medpace Investors, your election to tender Eligible Options will constitute a binding agreement between Medpace Investors and you with respect to the Eligible Options tendered on this Election Form, unless you return a validly completed Withdrawal Notice with respect to your tendered Eligible Options before the Expiration Date. Please note, if you elect to tender all or a portion of your Eligible Options, you may only withdraw your whole tender and not a portion thereof.

For purposes of participating in the Offer, you hereby agree to sell your Eligible Options as indicated below to Medpace Investors. You understand that such Eligible Options will be owned and held by Medpace Investors after the Expiration Date and acceptance by Medpace Investors.

You authorize Medpace, Inc. (“Medpace”) or a subsidiary of Medpace to withhold all applicable income tax, payroll tax, social insurance contributions and any other taxes legally payable by you with respect to the exchange of Eligible Options for cash and/or the cash payment (“Tax-Related Items”) from the cash payment amount, from your wages or other cash compensation paid to you by Medpace Investors. Alternatively, if Medpace or a subsidiary of Medpace does not withhold the Tax-Related Items from you, you shall pay to Medpace or a subsidiary of Medpace any amount of Tax-Related Items that it may be required to withhold as a result of your participation in the Offer and/or receipt of the cash payment. You acknowledge that it is your responsibility to report and pay any Tax-Related Items that Medpace or a subsidiary of Medpace does not withhold from you.

By signing this Election Form below, you acknowledge and agree to the following: (1) you understand that the cash payment may be taxable to you and that Medpace Investors does not assure you of any particular tax result related to participating in the Offer and that you may be subject to more taxes as a result of your participation in the Offer than you would have been subject to on your Eligible Options; (2) you understand that if you already paid tax on your Eligible Options and you participate in the Offer, you may not be able to obtain a refund or tax credit for the taxes already paid on the Eligible Options; (3) you understand that if you are tax resident in multiple jurisdictions, your cash payment may be subject to tax in multiple jurisdictions; (4) you agree that the Eligible Options granted to you were granted on a discretionary basis and that you have no entitlement to receive any future options or benefits in lieu of options regardless of whether you participate in this Offer; (5) you agree that the grant of Eligible Options is voluntary and occasional; (6) you are voluntarily participating in this Offer; (7) the payment for Eligible Options does not constitute employment compensation and is outside of the scope of your employment contract (if any); (8) the Offer is a one-time only offer and Medpace Investors does not have any obligation to offer future exchanges; (9) you understand that the potential value of the Eligible Options may be more than the cash payment you are receiving; (10) neither your participation in the Offer nor your participation in any equity compensation plan creates a right to further employment with Medpace or a subsidiary of Medpace and shall not interfere with the ability of Medpace or a subsidiary of Medpace to terminate your employment relationship at any time with or without cause, in compliance with applicable laws; (11) you agree that neither the cash payment nor the Eligible Options are part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services to Medpace or a subsidiary of Medpace; and (12) you acknowledge that Medpace Investors has advised you to consult with your own legal, accounting and tax advisors as to the consequences of participating or not participating in this Offer before making any decision whether to participate.
