Oct 17 (Reuters) - Continental Resources Inc (CLR.N) said on Monday it had agreed to be taken private by billionaire-founder Harold Hamm in a deal that would value the U.S. shale producer at about $27 billion. Smead Capital Management, the largest shareholder after the Hamm family with around 2%, had said in June the original offer "undervalues" the company.

Hamm founded Continental, the largest oil and gas producer in the Bakken shale, as Shelly Dean Oil Company in 1967, and ran it as a private firm until 2007.
