Enclosed for your consideration are the Prospectus/Offer to Exchange dated November 8, 2018 and the related Letter of Transmittal (the "Letter of Transmittal"), which together set forth the offer of WillScot Corporation (the "Company"), a Delaware corporation, to each holder of its warrants issued under the warrant agreement dated September 10, 2015 by and between Double Eagle Acquisition Corp. and Continental Stock Transfer & Trust Company, as warrant agent, to purchase one half of one share of Class A Common Stock, par value $0.0001 per share (the "Common Stock"), of the Company for a purchase price of $5.75 per half share ($11.50 per whole share) (the "Warrants") to receive 0.18182 shares of Common Stock in exchange for each Warrant tendered by the holder and exchanged pursuant to the offer (the "Offer"). The Offer is made solely upon the terms and conditions in the Prospectus/Offer to Exchange and in the Letter of Transmittal. The Offer will be open until 11:59 p.m., Eastern Time, on December 6, 2018, or such later time and date to which the Company may extend. The period during which the Offer is open, giving effect to any withdrawal or extension, is referred to as the "Offer Period."

Each Warrant holder whose Warrants are exchanged pursuant to the Offer will receive 0.18182 shares of Common Stock for each Warrant tendered by such holder and exchanged. Any Warrant holder that participates in the Offer may tender less than all of its Warrants for exchange.

No fractional shares of Common Stock will be issued pursuant to the Offer. In lieu of issuing fractional shares, any holder of Warrants who would otherwise have been entitled to receive fractional shares pursuant to the Offer will, after aggregating all such fractional shares of such holder, be paid cash (without interest) in an amount equal to such fractional part of a share multiplied by the last sale price of the Common Stock on the Nasdaq Capital Market on the last trading day of the Offer Period. The Company's obligation to complete the offer is not conditioned on the receipt of a minimum number of tendered warrants.

Warrants not exchanged for shares of Common Stock pursuant to the Offer will remain outstanding subject to their current terms, including any such terms permitting the Company to redeem such Warrants prior to their expiration. The Company reserves the right to redeem any of the Warrants, as applicable, pursuant to their current terms at any time, including prior to the completion of the Offer.

THE OFFER IS NOT MADE TO THOSE HOLDERS WHO RESIDE IN STATES OR OTHER JURISDICTIONS WHERE AN OFFER, SOLICITATION OR SALE WOULD BE UNLAWFUL.

Please follow the instructions in this document and the related documents, including the accompanying Letter of Transmittal, to cause your Warrants to be tendered for exchange pursuant to the Offer.

On the terms and subject to the conditions of the Offer, the Company will allow the exchange of all Warrants properly tendered before the Expiration Date and not properly withdrawn, at an exchange rate of 0.18182 shares of Common Stock for each Warrant so tendered.

We are the owner of record of Warrants held for your account. As such, only we can exchange and tender your Warrants, and then only pursuant to your instructions. We are sending you the Letter of Transmittal for your information only; you cannot use it to exchange and tender Warrants we hold for your account.

Please instruct us as to whether you wish us to tender for exchange any or all of the Warrants we hold for your account, on the terms and subject to the conditions of the Offer.

If you wish to have us tender any or all of your Warrants for exchange pursuant to the Offer, please so instruct us by completing, executing, detaching and returning to us the attached Instructions Form. If you authorize us to tender your Warrants, we will tender for exchange all of your Warrants unless you specify otherwise on the attached Instruction Form.

Your prompt action is requested. Your Instruction Form should be forwarded to us in ample time to permit us to submit a tender on your behalf before the Expiration Date. Please note that the Offer and withdrawal rights will expire at 11:59 p.m., Eastern Time, on December 6, 2018, or such later time and date to which the Company may extend.

The board of directors of the Company has approved the Offer. However, neither the Company nor any of its management, its board of directors, the dealer manager, the information agent, or the exchange agent for the Offer is making any recommendation as to whether holders of Warrants should tender Warrants for exchange in the Offer. The Company has not authorized any person to make any recommendation. You should carefully evaluate all information in the Prospectus/Offer to Exchange and in the Letter of Transmittal, and should consult your own investment and tax advisors. You must decide whether to have your Warrants exchanged and, if so, how many Warrants to have exchanged. In doing so, you should read carefully the information in the Prospectus/Offer to Exchange and in the Letter of Transmittal.
