Introductory Note

Pursuant to Rule 13d-2 promulgated under the Act, this Amendment No. 5 (“Amendment No. 5”) amends the Schedule 13D filed on July 17, 2009 (the “Original 13D”), Amendment No. 1 filed on September 1, 2009 (“Amendment No. 1”), Amendment No. 2 filed on September 8, 2009, (“Amendment No. 2”), Amendment No. 3 filed on January 19, 2010 (“Amendment No. 3”) and Amendment No. 4 filed on November 22, 2013 (“Amendment No. 4,” and together with Amendment No. 3, Amendment No. 2, Amendment No. 1, the Original 13D and this Amendment No. 5, the “Schedule 13D”). This Amendment No. 5 relates to the Common Shares (the “Shares”) of Tesco Corporation (the “Issuer”). Capitalized terms used herein which are not defined herein have the meaning given to them in the Original 13D.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is hereby supplemented as follows:

On March 10, 2014, LRP V sold 1,500,000 Shares pursuant to Rule 144 of the Securities Act of 1933, as amended (the “Securities Act”), at price of $17.06 per share.

Item 5. Interest in Securities of the Issuer

Items 5(a), 5(b) and 5(c) of the Original 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3 and Amendment No. 4 are hereby amended and restated in their entirety as follows:

(a) The percentages used herein are calculated based upon the 39,690,056 Shares that were outstanding as of February 28, 2014 as reported in the Issuer’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013. The number of Shares that may be deemed to be beneficially owned by the Reporting Persons, and the percentage of the outstanding shares represented thereby, in each case as reported in this Amendment No. 5, are based on the number of Shares owned by the Reporting Persons as of March 10, 2014.

Due to their respective relationships with each other, as of March 10, 2014, (i) each of the Reporting Persons may be deemed to beneficially own, in the aggregate, 4,307,799 Shares, representing approximately 10.85% of the outstanding class of Shares and (ii) Mr. Reynolds may be deemed to directly beneficially own, in the aggregate, 30,032 Shares, representing less than 1% of the outstanding class of Shares.

(b) Each of LRP, GP LP and GP Inc. may be deemed to share with LRP V the power to vote or to direct the vote and to dispose or to direct the disposition of the 4,307,799 Shares LRP V may be deemed to beneficially own as of March 10, 2014. Mr. Reynolds has the sole power to vote and dispose of the Shares owned by him. Neither the filing of the Schedule 13D nor any of its respective contents shall be deemed to constitute an admission that any Reporting Person or any of its affiliates is the beneficial owner of any Shares for purposes of Section 13(d) of the Act, or for any other purpose.

(c) On March 10, 2014, LRP V sold 1,500,000 Shares pursuant to Rule 144 of the Securities Act at price of $17.06 per share. There were no other transactions in the Shares effected by the Reporting Persons, nor, to the best of their knowledge, any of their directors, executive officers, general partners or members during the last sixty (60) days.
