The Company shall provide annual financial information to the Investors in the form provided in the attached PFIC Exhibit in Exhibit D (or in such other form as may be required to reflect changes in applicable law) as soon as reasonably practicable following the end of each taxable year of the Company (but in no event later than forty-five (45) days following the end of each such taxable year). The Company shall also obtain and provide any and all other information reasonably deemed necessary by the U.S. Investors to comply with the provisions of this Section 3.3(a). The Company shall, upon the written request of any U.S. Investor, appoint an internationally reputable accounting firm acceptable to the Investor to prepare and submit the Company’s U.S. tax filings.

(b) If a determination is made by the Company that the Company is a PFIC for a particular taxable year, then (i) for such year and for each year thereafter, the Company shall also provide each known U.S. Investor within sixty (60) days upon the request of such U.S. Investor with a completed “PFIC Annual Information Statement” as required by Treasury Regulation Section 1.1295-1(g) and any other information reasonably required by a U.S. Investor to comply with any reporting or other requirements in connection with the QEF Election; and (ii) to the extent permitted by Law, the Company agrees to make a dividend distribution to each U.S. Investor (no later than forty-five (45) days following the end of the Company’s taxable year or, if later, forty-five (45) days after the Company is informed by the Investor that such Investor’s Partner has been required to recognize such an income inclusion) in an amount equal to 50% of the amount that would be included by such U.S. Investor if the Investor were a “United States Person” as such term is defined in Section 7701(a)(30) of the Code and had the Investor made a valid and timely QEF Election which was applicable to such taxable year.

(c) In the event that the Company is determined by counsel or accountants for an Investor to be a controlled foreign corporation as described in Section 957 of the Code (a “CFC”) with respect to the shares held by the Investor, the Company agrees (i) to use commercially reasonable efforts to avoid generating Subpart F Income (as defined in Section 952 of the Code) (“Subpart F Income”); and (ii) to the extent permitted by Law, to annually make dividend distributions to each U.S. Investor in an amount equal to 50% of any income that would have been deemed distributed to such U.S. Investor pursuant to Section 951(a) of the Code had the Investor been a “United States shareholder” with respect to the Company as such term is defined in Section 951(b) of the Code (or such lesser amount determined by the Investor in its sole discretion).

Company’s capitalization table as of the end of the last day of such taxable year and (ii) a report regarding the Company’s status as a CFC. In addition, the Company shall provide each U.S. Investor with access to such other Company information as may be reasonably required by the Investor to determine the Company’s status as a CFC and to determine whether the Investor or any of the Investor’s Partners is required to report its pro rata portion of the Company’s Subpart F Income on its United States federal income tax return, or to allow the Investor or such Investor’s Partners to otherwise comply with applicable United States federal income tax laws.

The Company, will also provide any known U.S. Investor with any information reasonably requested to allow such U.S. Investor (and any equity-holder of a U.S. Investor) to comply with any applicable U.S. federal income tax Law (including maintaining any tax election made by such U.S. Investor or equity holder thereof, and including but not limited to information relating to the transfer of any equity interests of the Company (or any Subsidiary) and the issuance or redemption by the Company (or any Subsidiary) of any equity interests).

(e) The Company shall take such actions, including making an election to be treated as a corporation or refraining from making an election to be treated as a partnership, as may be required to ensure that at all times the Company is treated as corporation for United States federal income tax purposes.

(b) Within twenty (20) calendar days after receipt of the Offer Notice, each Offeree shall have an option to elect to purchase its respective Pro Rata Share of the Additional Equity Securities at the same price and subject to the same terms as specified in the Offer Notice.

(c) Each Offeree may exercise such purchase option and thereby, purchase all or any portion of its Pro Rata Share (with the re-allotments as provided below) of the Additional Equity Securities, by notifying the Company in writing, before the expiration of the twenty (20) calendar days period as to the number of such Additional Equity Securities which it wishes to purchase (including the re-allotments).

(d) Should any Offeree fails to exercise the right to purchase its full Pro Rata Share of the Additional Equity Securities, the Company shall give each Offeree which fully exercises its right of first offer under Section 4.1(c) above (an “Exercising Holder”) a written notice (“Additional Offer Notice”) which shall include all the information required in the Offer Notice and shall additionally identify the portion of the Additional Equity Securities not purchased by the Offerees (the “Remaining Securities”).

(e) Each Exercising Holder shall have an additional re-allotment right to purchase its Pro Rata Share of the Remaining Securities (if any) for a period of ten (10) calendar days commencing immediately after receipt of the Additional Offer Notice. Each Exercising Holder may exercise such re-allotment right to purchase all or a portion of its respective Pro Rata Share of the Remaining Securities by notifying the Company in writing, before the expiration of the ten (10) calendar days period as to the number of such Remaining Securities which it wishes to purchase. Each Exercising Holder’s “Pro Rata Share” for purposes of this Section 4.1(e) is the ratio of (x) the number of Ordinary Shares (calculated on an as-if-converted fully-diluted basis) held by such Exercising Holder on the date of the Offer Notice, to (y) the total number of Ordinary Shares (calculated on an as-if-converted fully-diluted basis) held by all of the Exercising Holders on the date of the Offer Notice.

Any failure of the such Offeree to execute such New SPA within the SPA Execution Period pursuant to this Section shall be deemed as a waiver of such Offeree’s right to purchase, and the Company shall be entitled to proceed with the issuance of Additional Equity Securities at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Offer Notice. For the purpose of this Section, the “SPA Execution Period” shall expire upon thirty (30) days after the date of such Offeree’s written notice to the Company of its desire to purchase certain number of Additional Equity Securities pursuant to Section 4.1(b) and Section 4.1(e), as applicable.

(g) The right of first offer set forth in this Section 4.1 may not be assigned or transferred except that such right is assignable by an Offeree to any Affiliate of such Offeree.

4.2 To the extent that the Offerees have not exercised their rights to purchase all the Additional Equity Securities within the time periods specified in Section 4.1, the Company may, for a period of ninety (90) calendar days following the expiration of such rights, have a right to offer such Additional Equity Securities not purchased by the Offerees to third-party offerees upon terms and conditions (including the purchase price) no more favorable than those specified in the Offer Notice. In the event that (i) the Company fails to enter into an agreement for the sale of the Additional Equity Securities not purchased by the Offerees to the prospective offerees within the foregoing ninety (90) day period; or (ii)

Each Shareholder agrees to vote all of its Shares from time to time and at all times, in whatever manner shall be necessary to authorize an increase in the authorized share capital of the Company and the Company shall at all times reserve and keep available out of its authorized but unissued Ordinary Shares such number of its Ordinary Shares so that there will be sufficient Ordinary Shares available for conversion of all of the then-outstanding Preferred Shares at any time that an adjustment to the relevant conversion price with respect to the Preferred Shares is made under the Articles.

5.6 Specific Enforcement

Each Party hereto acknowledges and agrees that any breach of this Agreement would result in substantial harm to the other Parties hereto for which monetary damages alone could not adequately compensate. Therefore, the Parties hereto unconditionally and irrevocably agree that any non-breaching Party hereto shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity (including, without limitation, seeking specific performance or the rescission of purchases, sales and other transfers of Shares not made in strict compliance with this Agreement).

5.7 Term

The provisions of this Section 5 shall be effective as of the date hereof and shall continue in effect until and shall terminate upon the earlier to occur of (a) immediately prior to the consummation of an IPO; and (b) a Liquidation Event in which the Investors will receive cash or publicly traded securities or a combination of the foregoing; provided, however, that the provisions of Section 5.5 shall survive until the holders of Preferred Shares have converted all of their Preferred Shares into Ordinary Shares.

6. RIGHT OF FIRST REFUSAL, CO-SALE AND RESTRICTIONS ON SALE

6.1 Restrictions on Transfer

(a) Transfer of Shares

Subject to Section 6.6, any proposed assignment, sale, offer to sell, pledge, mortgage, hypothecation, encumbrance, disposition of or any other like transfer or encumbering, through one or a series of transactions, of any interest in any Shares now or hereafter owned or held by a Shareholder, either directly or indirectly (in each case, a “Transfer”) shall be made in compliance with the terms of

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement 10

this Section 6. For the avoidance of doubt, any change in the equity interest of any Founder Holdco (or any entity that directly or indirectly holds any equity interest in any Founder Holdco), including without limitation as a result of (i) the issuance or redemption by such Founder Holdco (or any entity that directly or indirectly holds any equity interest in any Founder Holdco) of any portion of its outstanding shares or equity; or (ii) a Transfer of any equity interest of any Founder Holdco (any entity that directly or indirectly holds any equity interest in any Founder Holdco) by its equity holder, shall constitute a “Transfer” for purposes of this Agreement.

(b) Prohibition on Transfer of Ordinary Shares held by the Founder Holdcos

In addition to the restrictions set forth in Sections 6.2 and 6.3, prior to the consummation of a Qualified IPO or a Liquidation Event in which the Investors will receive cash or publicly traded securities or a combination of the foregoing, each Founder Holdco (each a “Restricted Shareholder”) shall not effectuate a Transfer, nor shall any Founder effectuate a Proposed Transfer (as defined below) of it/his/her shares in any Founder Holdco, unless otherwise approved in writing by a majority of members of the Board, including all of the Preferred Directors.

Notwithstanding the foregoing and anything to the contrary herein, none of the Founder or Founder Holdco shall effectuate a Transfer, directly or indirectly, of the Company’s shares it/he/she holds to any Sina Competitor, unless and until Sina has provided its written consent.

(c) Prohibition on Issuance of Shares or Similar Rights by the Founder Holdcos

Each Founder Holdco shall not, and each Founder shall procure such Founder Holdco not to, prior to the consummation of a Qualified IPO or a Liquidation Event in which the Investors will receive cash or publicly traded securities or a combination of the foregoing, issue the Founder Holdco’s shares, any debenture or obligation in whatsoever nature that is convertible into or exercisable for the Founder Holdco’s shares, any other right that may grant the recipient rights and privileges similar to that of a shareholder of the Founder Holdco, or in any other manner that may have similar effect to any of the above, unless otherwise approved in writing by a majority of members of the Board, including all of the Preferred Directors.

6.2 Right of First Refusal

(a) Proposed Transfer Notice

Each Restricted Shareholder (including its successors and permitted assignees) (a “Transferor”) proposing to make a Transfer (a “Proposed Transfer”) must deliver a notice (the “Proposed Transfer Notice”) to each holder of any Preferred Shares (each an “Eligible Holder”, collectively the “Eligible Holders”) no later than forty-five (45) calendar days prior to the consummation of such Proposed Transfer. Such Proposed Transfer Notice shall contain the material terms and conditions of the Proposed Transfer, including without limitation a description of the Shares (the “Transfer Shares”) that such Transferor proposes to transfer, the transfer price for the Transfer Shares and the identity of the Prospective Transferee. In the event of a conflict between this Agreement and any other agreement that may have been entered into by a Transferor with an Eligible Holder that provides a preexisting right of first refusal, the terms of this Agreement shall prevail and the preexisting right of first refusal shall be deemed satisfied by compliance with this Section 6.2.

(b) Grant of Right of First Refusal to Eligible Holders. Each Transferor hereby unconditionally and irrevocably grants to each Eligible Holder (including its successors and permitted assignees) a right of first refusal (the “Right of First Refusal”) to purchase all or any portion of its Pro-Rata ROFR Share (as defined below) of any Transfer Shares. To exercise its Right of First Refusal, an Eligible Holder must deliver an exercise notice to the Transferor and the Company indicating the number of Transfer Shares such Eligible Holder wishes to purchase within thirty (30) calendar days after delivery of the Proposed Transfer Notice (the “ROFR Exercise Period”).

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement 11

An Eligible Holder’s “Pro-Rata ROFR Share” shall mean that number equals to the number of Transfer Shares, multiplied by (i) the number of Ordinary Shares then held by such Eligible Holder (on an as-if-converted fully-diluted basis and including Ordinary Shares issued upon conversion thereof), divided by (ii) the total number of Ordinary Shares (on an as-if-converted fully-diluted basis and including Ordinary Shares issued upon conversion thereof) then held by all Eligible Holders.

(c) Re-allotment Notice of Transfer Shares. Should any Eligible Holder fails to purchase its full Pro-Rata ROFR Shares within the ROFR Exercise Period, then, within five (5) calendar days after the expiration thereof, the Transferor shall send a written notice (the “Re-allotment Notice”) to each Eligible Holder who has fully exercised its Right of First Refusal in accordance with Section 6.2(b) above (each an “Exercising Eligible Holder”). Such Re-allotment Notice shall include all the information required in the Proposed Transfer Notice and shall additionally identify the portion of the Transfer Shares which are not purchased by the Eligible Holders (the “Remaining Transfer Shares”).

(d) Re-allotment of Transfer Shares. Each Exercising Eligible Holder shall have a re-allotment right to purchase all or any portion of its pro rata share of the Remaining Transfer Shares on the terms and conditions set forth in the Proposed Transfer Notice. To exercise such re-allotment right with respect to the Remaining Transfer Shares, an Exercising Eligible Holder must deliver to the Transferor and the Company an exercise notice indicating the additional number of Transfer Shares that it wishes to purchase within ten (10) calendar days after its receipt of the Re-allotment Notice (the “Re-allotment Exercise Period”). Within five (5) calendar days after the expiration of the Re-allotment Exercise Period, the Transferor shall give written notice to the Company and each Eligible Holder confirming and specifying the number of Transfer Shares that such Eligible Holder has elected to purchase (including any re-allotments) by exercising its Right of First Refusal pursuant to this Section 6.2 (the “Confirmation Notice”).

For the purpose of this Section 6.2(d), an Exercising Eligible Holder’s pro rata share of the Remaining Transfer Shares shall be equal to the number of the Remaining Transfer Shares, multiplied by (i) the number of Transfer Shares to be purchased by such Exercising Eligible Holder pursuant to Section 6.2(b) above, divided by (ii) the total number of Transfer Shares to be purchased by all the Exercising Eligible Holders pursuant to Section 6.2(b) above.

(e) Consideration; Closing. Should the purchase price of the Transfer Shares specified in the Proposed Transfer Notice be payable in property, services or other non-cash consideration, each Eligible Holder shall have the right to pay the purchase price in the form of cash equal in amount to the value of such non-cash consideration. If the Transferor and the Eligible Holder fail to agree on such cash value within ten (10) days after the date on which the Eligible Holder exercises its Right of First Refusal pursuant to Section 6.2(b) above, the valuation shall be determined by the Board (including the affirmative consents of the Majority Preferred Directors) in good faith. The closing of the purchase of the Transfer Shares by the Eligible Holders shall take place, and the consideration payable by such Eligible Holders for the Transfer Shares shall have been delivered to the Transferor, by the later of (i) the intended closing date specified in the Proposed Transfer Notice; and (ii) ten (10) calendar days after delivery of the Confirmation Notice.

6.3 Right of Co-Sale

(a) If any Transfer Shares subject to a Proposed Transfer are not purchased pursuant to Section 6.2 above and thereafter are to be sold to a Prospective Transferee (such Transfer Shares, the “Co-Sale Eligible Shares”), each Eligible Holder that has not exercised its rights under Section 6.2(b) (each a “Co-Sale Eligible Holder”) may elect to exercise its right (a “Right of Co-Sale”) and participate on a pro-rata basis in the Proposed Transfer on the same terms and conditions specified in the Proposed Transfer Notice. To exercise its Right of Co-Sale, the Co-Sale Eligible Holder must give the Transferor written notice to that effect within fifteen (15) calendar days (the “Co-Sale Period”) after receipt of the Confirmation Notice as provided in Section 6.2(d), and upon giving such notice the Co-Sale Eligible Holder shall be deemed to have effectively exercised the Right of Co-Sale.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement 12

(b) Each Co-Sale Eligible Holder, by timely exercising its Right of Co-Sale by delivering the written notice provided for above in Section 6.3(a) may include in the Proposed Transfer all or any part of its Shares equal to the product obtained by multiplying (i) the aggregate number of Co-Sale Eligible Shares by (ii) a fraction, the numerator of which is the number of Shares (calculated on an as-if-converted fully-diluted basis) owned by such Co-Sale Eligible Holder on the date of the Confirmation Notice and the denominator of which is the total number of Shares owned, in the aggregate, by all Co-Sale Eligible Holders, plus the number of Shares held by the Transferor, each on the date of the Confirmation Notice and each calculated on an as-if-converted fully-diluted basis. To the extent that one or more of the Co-Sale Eligible Holders exercise such Right of Co-Sale in accordance with the terms and conditions set forth herein, the number of Co-Sale Eligible Shares that the Transferor may sell in the Proposed Transfer shall be correspondingly reduced.

(c) The sale of the remaining Co-Sale Eligible Shares and the Shares to be transferred by the Co-Sale Eligible Holders shall occur simultaneously within ninety (90) calendar days from the expiration of the Co-Sale Period (the “Co-sale Closing”). For the avoidance of doubt, the Right of Co-Sale shall not apply with respect to Transfer Shares sold or to be sold to the Eligible Holders under the Right of First Refusal in Section 6.2.

(d) A Co-Sale Eligible Holder shall effect its participation in the Proposed Transfer by delivering to the Transferor, prior to the Co-Sale Closing, a signed instrument of transfer and one or more share certificates, properly endorsed for transfer to the Prospective Transferee, representing:

(i) the number of Ordinary Shares that such Eligible Holder elects to include in the Proposed Transfer; or

(ii) the number of Preferred Shares that are at such time convertible into the number of Ordinary Shares that such Eligible Holder elects to include in the Proposed Transfer; provided, however, that if the Prospective Transferee objects to the delivery of convertible Preferred Shares in lieu of the Ordinary Shares, such Eligible Holder shall first convert the Preferred Shares into Ordinary Shares and deliver such Ordinary Shares as provided above. The Company agrees to make any such conversion concurrent with and contingent upon the actual transfer of such shares to the Prospective Transferee.

(e) The terms and conditions of any sale pursuant to this Section 6.3 will be contained in, and governed by, a written purchase and sale agreement with customary terms and provisions for such a transaction.

(f) The register of members of the Company will be updated in consummation of the sale of the Transfer Shares pursuant to the terms and conditions specified in the Proposed Transfer Notice and the purchase and sale agreement, and the Transferor shall concurrently therewith remit to each Co-Sale Eligible Holder the portion of the sale proceeds to which such Co-Sale Eligible Holder is entitled by reason of its participation in such sale. If any Prospective Transferee refuses to purchase securities subject to the Right of Co-Sale from any Co-Sale Eligible Holder exercising its Right of Co-Sale hereunder, no Transferor may sell any Transfer Shares to such Prospective Transferee unless and until, simultaneously with such sale, such Transferor purchases all securities subject to the Right of Co-Sale from such Co-Sale Eligible Holder.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement 13

6.4 Severability

The exercise or election not to exercise any right by any Eligible Holder hereunder shall not adversely affect its right to participate in any other sales of Transfer Shares subject to this Section 6.

6.5 Effect of Failure to Comply

(a) Any Proposed Transfer not made in compliance with the requirements of this Agreement (including without limitation this Section 6) shall be null and void ab initio, shall not be recorded on the books or register of the Company or its transfer agent and shall not be recognized by the Company.

(b) If the Transferor purports to sell any Shares in contravention of the Right of Co-Sale (a “Prohibited Transfer”), each Eligible Holder, in addition to such remedies as may be available by Law, in equity or hereunder, is entitled to require such Transferor to purchase Shares from the Eligible Holder, as provided below, and such Transferor will be bound by the terms of such option. If a Transferor makes a Prohibited Transfer, each Eligible Holder upon timely exercise of its Right of Co-Sale under Section 6.3 may require such Transferor to purchase from such Eligible Holder the type and number of Shares that such Eligible Holder would have been entitled to sell to the Prospective Transferee under Section 6.3 had the Prohibited Transfer been effected pursuant to and in compliance with the terms of Section 6.3. The sale will be made on the same terms and subject to the same conditions as would have applied had the Transferor not made the Prohibited Transfer, except that the sale (including, without limitation, the delivery of the purchase price) must be made within ninety (90) days after the Eligible Holder learns of the Prohibited Transfer, as opposed to the timeframe prescribed in Section 6.3. Such Transferor shall also reimburse such Eligible Holder for any and all fees and expenses, including legal fees and expenses, incurred pursuant to the exercise or the attempted exercise of such Eligible Holder’s rights under Section 6.3.

6.6 Exempt Transfers

Notwithstanding the foregoing or anything to the contrary herein, the provisions of Section 6.1(b), Section 6.1(c), Section 6.2 and Section 6.3 shall not apply to: (i) any redemption of Shares pursuant to the Articles; (ii) a Transfer of any equity securities of the Company now or hereafter held by a Founder or a Founder Holdco to such Founder’s parents, children, spouse, or to a trustee, executor, or other fiduciary for the benefit of such Founder or such Founder’s parents, children, spouse for bona fide estate planning purposes and/or the wholly-owned subsidiaries of such Founder Holdco; or (iii) the sale of any Shares to the public in an IPO.

The Parties agree that Transfer of any Shares held by the Investors shall not be subject to any right of first refusal or tag along right or other similar rights of any other shareholders.

6.7 Term

The provisions of this Section 6 shall terminate upon the earlier of (i) immediately prior to a Qualified IPO; and (ii) a Liquidation Event in which the Investors will receive cash or publicly traded securities or a combination of the foregoing.

7. ADDITIONAL COVENANTS

7.1 Share Incentive Plan

The Company shall maintain the 2017 Share Plan, as amended from time to time (the “Share Plan”) under which the Company may reserve not more than 21,967,694 Ordinary Shares for issuance to officers, directors, employees and consultants of the Company.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement 22

THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO, AND IN CERTAIN CASES PROHIBITED BY, THE TERMS AND CONDITIONS OF A CERTAIN SHAREHOLDERS’ AGREEMENT BY AND AMONG THE SHAREHOLDER, THE COMPANY AND CERTAIN OTHER HOLDERS OF SHARES OF THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.

(b) The Founders and the Founder Holdcos agree that the Company may instruct its transfer agent to impose transfer restrictions on the shares represented by certificates bearing the legend referred to in Section 8.13(a) above to enforce the provisions of this Agreement, and the Company agrees to promptly do so. The legend shall be removed upon termination of this Agreement at the request of the Holder.

8.12 Dispute Resolution

(a) Any dispute arising out of or in connection with this Agreement, including any question regarding its existence, validity or termination, shall be referred to representatives of the Investors and the Company for settlement through friendly consultations. In case no agreement can be reached through consultation within sixty (60) days from either Party’s written notice to the other for commencement of such consultations, either Party may submit the dispute to arbitration for settlement. Any and all such disputes shall be finally resolved by arbitration and the arbitration shall be conducted in Hong Kong under the auspices of the Hong Kong International Arbitration Centre (the “HKIAC”) in accordance with the Hong Kong International Arbitration Centre Administered Arbitration Rules (the “HKIAC Rules”). There shall be three (3) arbitrators. The complainant and the respondent to such dispute shall each select one (1) arbitrator within thirty (30) days after giving or receiving the demand for arbitration. Such arbitrators shall be freely selected, and the Parties shall not be limited in their selection to any prescribed list. The Chairman of the HKIAC shall select the third arbitrator, who shall be qualified to practice Law in Hong Kong. If either party to the arbitration does not appoint an arbitrator who has consented to participate within thirty (30) days after selection of the first arbitrator, the relevant appointment shall be made by the Chairman of the HKIAC. The arbitration shall be conducted in English.

(b) To the extent that the HKIAC Rules are in conflict with the provisions of this Section 8.12 (a) , including concerning the appointment of the arbitrators, the provisions of this Section 8.12 (a) shall prevail. The decision of the arbitration tribunal shall be final, conclusive and binding on the parties to the arbitration. Judgment may be entered on the arbitration tribunal’s decision in any court having jurisdiction. The parties to the arbitration shall each pay an equal share of the costs and expenses of such arbitration, and each party shall separately pay for its respective counsel fees and expenses; provided, however, that the prevailing party in any such arbitration shall be entitled to recover from the non-prevailing party its reasonable costs and attorney fees. The Parties acknowledge and agree that, in addition to contract damages, the arbitrators may award provisional and final equitable relief, including injunctions, specific performance, and lost profits.

8.13 Delays or Omissions

No delay or omission to exercise any right, power or remedy accruing to any Party under this Agreement, upon any breach or default of any other Party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting Party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any Party of any breach or default under this Agreement, or any waiver on the part of any Party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any Party, shall be cumulative and not alternative.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement 23

The Founders shall procure the Founder Holdcos controlled by him/her to fully comply with and perform all of the obligations, covenants, undertakings and commitments of such Founder Holdcos under this Agreement.

(b) Notwithstanding any other provision of this Agreement, if the managing underwriter(s) determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriter(s) may exclude shares from the registration and the underwriting, and the number of shares that may be included in the registration and the underwriting shall be allocated, first, to the Company, second, to each of the Investors requesting inclusion of their Registrable Securities in such registration statement on a pro rata basis based on the total number of shares of Registrable Securities then held by each such Investor, third, to the other Holders requesting inclusion of their Registrable Securities in such registration statement on a pro rata basis based on the total number of shares of Registrable Securities then held by each such Holder and fourth, to holders of other securities of the Company; provided, however, that the right of the underwriter(s) to exclude shares (including Registrable Securities) from the registration and underwriting as described above shall be restricted so that (i) the number of Registrable Securities included in any such registration is not reduced below twenty-five percent (25%) of the aggregate number of shares of Registrable Securities for which inclusion has been requested; and (ii) all shares that are not Registrable Securities and are held by any other person, including, without limitation, any person who is an employee, officer or director of the Company (or any subsidiary of the Company) shall first be excluded from such registration and underwriting before any Registrable Securities are so excluded, unless otherwise approved by the holders of a majority of the Registrable Securities. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter(s), delivered at least ten (10) Business Days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration.

3.3 Not Demand Registration

Registration pursuant to this Section 3 shall not be deemed to be a demand registration as described in Section 2 above. There shall be no limit on the number of times the Holders may request registration of Registrable Securities under this Section 3.

4. FORM S-3 REGISTRATION

In case the Company shall receive from any Holder or Holders of a majority of all Registrable Securities then Outstanding a written request or requests that the Company effect a registration on Form S-3 (or an equivalent registration in a jurisdiction outside of the United States) and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, then the Company will act upon the requirements set forth in Sections 4.1, 4.2, 4.3 and 4.4 accordingly.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement – Exhibit B

4.1 Notice

Promptly give written notice of the proposed registration and the Holder’s or Holders’ request therefor, and any related qualification or compliance, to all other Holders of Registrable Securities.

4.2 Registration

As soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holders or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within twenty (20) days after the Company provides the notice contemplated by Section 4.1; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 4:

(a) if Form S-3 is not available for such offering by the Holders;

(b) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than US$ 500,000;

(c) if the Company shall furnish to the Holders a certificate signed by the president or chief executive officer of the Company stating that in the good faith judgment of the Board of Directors, it would be materially detrimental to the Company and its shareholders for such FormS-3 Registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement no more than once during any twelve (12) month period for a period of not more than sixty (60) days after receipt of the request of the Holder or Holders under this Section 4; provided that the Company shall not register any of its other shares during such sixty (60) day period.

(d) if the Company has, within the six (6) month period preceding the date of such request, already effected a registration under the Securities Act other than a registration from which the Registrable Securities of Holders have been excluded (with respect to all or any portion of the Registrable Securities the Holders requested be included in such registration) pursuant to the provisions of Sections 2.2 and 3.2; or

(e) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance.

4.3 Not a Demand Registration

Form S-3 registrations shall not be deemed to be demand registrations as described in Section 2 above. Except as otherwise provided herein, there shall be no limit on the number of times the Holders may request registration of Registrable Securities under this Section 4.

4.4 Underwriting

If the Holders of Registrable Securities requesting registration under this Section 4 intend to distribute the Registrable Securities covered by their request by means of an underwriting, the provisions of Section 2.2 shall apply to such registration.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement – Exhibit B

5. EXPENSES

All Registration Expenses incurred in connection with any registration pursuant to Sections 2, 3 or 4 (but excluding Selling Expenses) shall be borne by the Company. Each Holder participating in a registration pursuant to Sections 2, 3 or 4 shall bear such Holder’s proportionate share (based on the total number of shares sold in such registration other than for the account of the Company) of all Selling Expenses or other amounts payable to underwriter(s) or brokers, in connection with such offering by the Holders. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 2 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered, unless the Holders of a majority of the Registrable Securities then Outstanding agree that such registration constitutes the use by the Holders of one (1) demand registration pursuant to Section 2 (in which case such registration shall also constitute the use by all Holders of Registrable Securities of one (1) such demand registration); provided further, however, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the condition, business, or prospects of the Company not known to the Holders at the time of their request for such registration and have withdrawn their request for registration with reasonable promptness after learning of such material adverse change, then the Holders shall not be required to pay any of such expenses and such registration shall not constitute the use of a demand registration pursuant to Section 2.

6. OBLIGATIONS OF THE COMPANY

Whenever required to effect the registration of any Registrable Securities under this Agreement the Company shall, as expeditiously as reasonably possible, act upon the requirements set forth in Sections 6.1, 6.2, 6.3, 6.4, 6.5, 6.6 and 6.7 accordingly.

6.1 Registration Statement

6.2 Amendments and Supplements

Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement.

6.3 Prospectuses

Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of the Registrable Securities owned by them that are included in such registration.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement – Exhibit B

6.4 Blue Sky

Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act.

6.5 Underwriting

In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement in usual and customary form, with the managing underwriter(s) of such offering.

6.6 Notification

Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of (i) the issuance of any stop order by the SEC in respect of such registration statement, or (ii) the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing.

6.7 Opinion and Comfort Letter

Furnish, at the request of any Holder requesting registration of Registrable Securities, on the date that such Registrable Securities are delivered to the underwriter(s) for sale, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the registration statement with respect to such securities becomes effective, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering and reasonably satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and (ii) letters dated as of (1) the effective date of the registration statement covering such Registrable Securities and (2) the closing date of the offering from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering and reasonably satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities.

7. FURNISH INFORMATION

It shall be a condition precedent to the obligations of the Company to take any action pursuant to Sections 2, 3 or 4 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to timely effect the Registration of their Registrable Securities.

8. INDEMNIFICATION

In the event any Registrable Securities are included in a registration statement under Sections 2, 3 or 4, the Company shall act upon the requirements set forth in Sections 8.1, 8.2, 8.3, 8.4 and 8.5 accordingly.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement – Exhibit B

8.1 By the Company

To the extent permitted by law, the Company will indemnify and hold harmless each Holder, its partners, officers, directors, legal counsel, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other United States federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”):

(a) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto;

(b) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading; or

(c) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any United States federal or state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any United States federal or state securities law in connection with the offering covered by such registration statement;

and the Company will reimburse each such Holder, its partner, officer, director, legal counsel, underwriter or controlling person for any legal or other expenses reasonably incurred by them, as incurred, in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 8.1 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder or any partner, officer, director, counsel, underwriter or controlling person of such Holder.

8.2 By Selling Holders

To the extent permitted by law, each selling Holder will, if Registrable Securities held by Holder are included in the securities as to which such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, directors, officers, legal counsel or any person who controls such Holder within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, legal counsel, controlling person, underwriter or other such Holder, partner or director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other United States federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, partner, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 8.2 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided further, that in no event shall any indemnity under this Section 8.2 exceed the net proceeds received by such Holder in the registered offering out of which the applicable Violation arises.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement – Exhibit B

8.3 Notice

Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnified party under this Section 8, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential conflict of interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of liability to the indemnified party under this Section 8 to the extent the indemnifying party is prejudiced as a result thereof, but the omission to so deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 8.

8.4 Contribution

In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any indemnified party makes a claim for indemnification pursuant to this Section 8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 8 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any indemnified party in circumstances for which indemnification is provided under this Section 8; then, and in each such case, the indemnified party and the indemnifying party will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion so that a Holder (together with its related persons) is responsible for the portion represented by the percentage that the public offering price of its Registrable Securities offered by and sold under the registration statement bears to the public offering price of all securities offered by and sold under such registration statement, and the Company and other selling Holders are responsible for the remaining portion. The relative fault of the indemnifying Party and of the indemnified Party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying Party or by the indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, that, in any such case: (A) no Holder will be required to contribute any amount in excess of the net proceeds to such Holder from the sale of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

8.5 Survival

The obligations of the Company and Holders under this Section 8 shall survive the completion of any offering of Registrable Securities in a registration statement, regardless of the expiration of any statutes of limitation or extensions of such statutes. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement – Exhibit B

9. NO REGISTRATION RIGHTS TO THIRD PARTIES

Without the prior written consent of the Holders of a majority in interest of the Registrable Securities then Outstanding, the Company covenants and agrees that it shall not grant, or cause or permit to be created, for the benefit of any person or entity any registration rights of any kind (whether similar to the demand, “piggyback” or Form S-3 registration rights described in this Exhibit B, or otherwise) relating to any securities of the Company which are senior to, or on a parity with, those granted to the Holders of Registrable Securities.

10. RULE 144 REPORTING

With a view to making available the benefits of certain rules and regulations of the SEC which may at any time permit the sale of the Registrable Securities to the public without registration or pursuant to a registration on Form S-3, after such time as a public market exists for the Ordinary Shares, the Company agrees to:

(a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times after the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public;

(b) File with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and

(c) So long as a Holder owns any Registrable Securities, to furnish to such Holder forthwith upon request (i) a written statement by the Company as to its compliance with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of the Company’s initial public offering), the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), or its qualification as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company, and (iii) such other reports and documents of the Company as a Holder may reasonably request in availing itself of any rule or regulation of the SEC that permits the selling of any such securities without registration or pursuant to Form S-3.

11. MARKET STAND-OFF

Each Shareholder agrees that, so long as it holds any voting securities of the Company, upon request by the Company or the underwriters managing the initial public offering of the Company’s securities, it will not sell or otherwise transfer or dispose of any securities of the Company (other than those permitted to be included in the registration and other transfers to Affiliates permitted by law) without the prior written consent of the Company or such underwriters, as the case may be, for a period of time specified by the representative of the underwriters not to exceed one hundred and eighty (180) days from the effective date of the registration statement covering such initial public offering or the pricing date of such offering as may be requested by the underwriters. The foregoing provision of this Section 11 shall not apply to the sale of any securities of the Company to an underwriter pursuant to any underwriting agreement. The Company shall require all future acquirers of the Company’s securities to execute prior to an IPO a market stand-off agreement containing substantially similar provisions as those contained in this Section 11.

EXHIBIT D

ANNUAL INFORMATION STATEMENT

(1)          This questionnaire applies to the taxable year of Tusimple (Cayman) Limited (the “Company”) beginning on [*], 20[*], and ending on [*], 20[*].

(2)          PLEASE CHECK HERE IF 75% OR MORE OF THE COMPANY’S GROSS INCOME CONSTITUTES PASSIVE INCOME.

Passive income: For purposes of this test, passive income includes:

• Dividends, interests, royalties, rents and annuities, excluding, however, rents and royalties which are received from an unrelated party in connection with the active conduct of a trade or business.

• Net gains from the sale or exchange of property—

which gives rise to dividends, interest, rents or annuities (excluding, however, property used in the conduct of a banking, finance or similar business, or in the conduct of an insurance business);

which is an interest in a trust, partnership, or REMIC; or

which does not give rise to income.

• Net gains from transactions in commodities.

• Net foreign currency gains.

• Any income equivalent to interest.

Look-through rule: if the Company owns, directly or indirectly, 25% of the stock by value of another corporation, the Company must take into account its proportionate share of the income received by such other corporation.

(3)          PLEASE CHECK HERE IF THE AVERAGE FAIR MARKET VALUE DURING THE TAXABLE YEAR OF PASSIVE ASSETS HELD BY THE COMPANY EQUALS 50% OR MORE OF THE AVERAGE FAIR MARKET VALUE OF ALL OF THE COMPANY’S ASSETS.

Note: This test is applied on a gross basis; no liabilities are taken into account.

Passive Assets: For purposes of this test, “passive assets” are those assets which generate (or are reasonably expected to generate) passive income (as defined above). Assets which generate partly passive and partly non-passive income are considered passive assets to the extent of the relative proportion of passive income (compared to non-passive income) generated in a particular taxable year by such assets. Please note the following:

• A trade or service receivable is non-passive if it results from sales or services provided in the ordinary course of business.

• Intangible assets that produce identifiable items of income, such as patents or licenses, are characterized in terms of the type of income produced.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement – Exhibit D

• Goodwill and going concern value must be identified to a specific income producing activity and are characterized in accordance with the nature of that activity.

• Cash and other assets easily convertible into cash are passive assets, even when used as working capital.

• Stock and securities (including tax-exempt securities) are passive assets, unless held by a dealer as inventory.

Average value: For purposes of this test, “average fair market value” equals the average quarterly fair market value of the assets for the relevant taxable year.

Look-through rule: if the Company owns, directly or indirectly, 25% of the stock by value of another corporation, the Company must take into account its proportionate share of the passive assets of such other corporation.

(4)          PLEASE CHECK HERE IF (A) MORE THAN 50% OF THE COMPANY’S STOCK (BY VOTING POWER OR BY VALUE) IS OWNED BY FIVE OR FEWER U.S. PERSONS OR ENTITIES AND (B) THE AVERAGE AGGREGATE ADJUSTED TAX BASES (AS DETERMINED UNDER U.S. TAX PRINCIPLES) DURING THE TAXABLE YEAR OF THE PASSIVE ASSETS HELD BY THE COMPANY EQUALS 50% OR MORE OF THE AVERAGE AGGREGATE ADJUSTED TAX BASES OF ALL OF THE COMPANY’S ASSETS.

Average value: For purposes of this test, “average aggregate adjusted tax bases” equals the average quarterly aggregate adjusted tax bases of the assets for the relevant taxable year.

Look-through rule: if the Company owns, directly or indirectly, 25% of the stock by value of another corporation, the Company must take into account its proportionate share of the passive assets of such other corporation.

(5) [INVESTOR] HAS THE FOLLOWING PRO-RATA SHARE OF THE ORDINARY EARNINGS AND NET CAPITAL GAIN OF THE COMPANY AS DETERMINED UNDER U.S. INCOME TAX PRINCIPLES FOR THE TAXABLE YEAR OF THE COMPANY:

Ordinary Earnings:                              (as determined under U.S. income tax principles)

Net Capital Gain:                                  (as determined under U.S. income tax principles)

Pro Rata Share: For purposes of the foregoing, the shareholder’s pro rata share equals the amount that would have been distributed with respect to the shareholder’s stock if, on each day during the taxable year of the Company, the Company had distributed to each shareholder its pro rata share of that day’s ratable share (determined by allocating to each day of the year, an equal amount of the Company’s aggregate ordinary earnings and aggregate net capital gain for such year) of the Company’s ordinary earnings and net capital gain for such year. Determination of a shareholder’s pro rata share will require reference to the Company’s charter, certificate of incorporation, articles of association or other comparable governing document.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement – Exhibit D

(6) The amount of cash and fair market value of other property distributed or deemed distributed by Company to [INVESTOR] during the taxable year specified in paragraph 1. is as follows:

Cash:                         

Fair Market Value of Property:                                 

(7) Company will permit [INVESTOR] to inspect and copy Company’s permanent books of account, records, and such other documents as may be maintained by Company that are necessary to establish that PFIC ordinary earnings and net capital gain, as provided in Section 1293(e) of the U.S. Internal Revenue Code of 1986, as amended (or any successor provision thereto), are computed in accordance with U.S. income tax principles.

Tusimple (Cayman) Limited – Seventh Amended and Restated Shareholders’ Agreement – Exhibit D

The foregoing representations are true and accurate as of the date hereof. If in any respect such representations shall cease to be true and accurate, the undersigned shall give immediate notice of such fact to [INVESTOR].
