LETTER OF TRANSMITTAL

FOR COMMON SHARES

OF

UNI-SELECT INC.

This Letter of Transmittal, properly completed and duly executed, together with all other required documents, must accompany certificates and/or DRS Advices for common shares (the "Shares") of Uni-Select Inc. (the "Company") deposited in connection with the proposed arrangement (the "Arrangement") involving the Company, LKQ Corporation ("LKQ") and 9485-4692 Québec Inc. (the "Purchaser"), a wholly-owned subsidiary of LKQ, pursuant to the arrangement agreement between the Company, LKQ and Purchaser dated as of February 26, 2023 (the "Arrangement Agreement") that is being submitted for approval at the special meeting of shareholders of the Company to be held on April 27, 2023 or any postponement or adjournment thereof (the "Meeting"), as further described in the management proxy circular of the Company dated March 23, 2023 (the "Circular"). Pursuant to the Plan of Arrangement, following the Effective Time, each holder of Shares (each, a "Shareholder") will receive, in exchange for each Share held, C$48.00 in cash (the "Consideration"), without interest and less any applicable withholdings.

Capitalized terms used but not defined in this Letter of Transmittal have the meanings set out in the Circular. Copies of the Arrangement Agreement and the Circular are available under the Company's profile on SEDAR atwww.sedar.com.

This Letter of Transmittal is for use by registered Shareholders only or their authorized representatives and is not to be used by non-registered Shareholders. Non-registered Shareholders beneficially own Shares that are not registered in their names but instead are registered in the name of an intermediary (an "Intermediary"), such as a broker, investment dealer, bank or trust company, or in the name of a depositary such as CDS Clearing and Depository Services Inc. in which the Intermediary is a participant. Non-registered Shareholders should contact their Intermediary for any questions regarding the process to deposit Shares and should carefully follow the instructions from the Intermediary.

In order to receive the Consideration under the Arrangement, registered Shareholders are required to deposit the certificate(s) and/or DRS Advice(s) representing the Shares held by them with Computershare Investor Services Inc. ("Computershare" or the "Depositary"). This Letter of Transmittal, properly completed and duly executed, together with all other documents required by the terms of the Arrangement and this Letter of Transmittal, must accompany any and all certificate(s) and/or DRS Advice(s) representing Shares deposited in exchange for the Consideration pursuant to the Arrangement. Any Letter of Transmittal, once deposited with the Depositary, will be irrevocable and may not be withdrawn by a registered Shareholder, unless the Arrangement is not completed and the Arrangement Agreement is terminated in accordance with its terms.

Following the Effective Time, whether or not registered Shareholders deliver this Letter of Transmittal and all other documents required by the terms of the Arrangement and this Letter of Transmittal, registered holders of Shares will cease to be Shareholders and, until duly surrendered to the Depositary, each certificate and/or DRS Advice that immediately prior to the Effective Time represented Shares will be deemed to represent only the right to receive, upon such surrender, the aggregate Consideration for such surrendered Shares, less applicable withholdings. Any such certificate and/or DRS Advice formerly representing Shares not duly surrendered on or before the third anniversary of the Effective Date shall cease to represent a claim by or interest of any former holder of Shares of any kind or nature against or in the Company, the Purchaser or LKQ, including a claim for dividends or other distributions. On such date, all cash to which such former Shareholder was entitled shall be deemed to have been surrendered to the Purchaser or the Company, as applicable, and shall be paid over by the Depositary to the Purchaser or as directed by the Purchaser.

Please note that the delivery of this Letter of Transmittal, together with the certificate(s) and/or DRS Advice(s) representing Shares, does not constitute a vote in favour of the Arrangement Resolution. To exercise the right to vote at the Meeting, Shareholders must follow the instructions provided in the Circular and on the form of proxy that accompanies the Circular.

If Shares are registered in different names, a separate Letter of Transmittal must be submitted for each different registered Shareholder. Any Letter of Transmittal, once deposited with the Depositary, will be irrevocable and may not be withdrawn by a Shareholder, unless the Arrangement is not completed and the Arrangement Agreement is terminated in accordance with its terms.
