( CNN ) -- Majid Shoukat Khan , a terror suspect who has been held at Guantanamo Bay , Cuba , pleaded guilty Wednesday to all charges as part of a deal that requires him to testify against other detainees . Khan , 32 , is expected to spend up to 19 years behind bars in exchange for the agreement , according to Army Col. James Pohl , the presiding military commission judge . `` If I keep my side of the bargain , they 'll keep their side of the bargain , '' Khan said during the proceeding Wednesday . He was charged with conspiracy , murder and attempted murder in violation of the law of war , providing material support for terrorism and spying . Pohl pronounced Khan guilty Wednesday and said the sentencing is expected to take place in four years . The defendant will be required to provide testimony against his fellow detainees during those years leading up to the sentencing . He 'll then receive credit for time served , leaving up to 15 years on his sentence , Pohl said . In the deal , Khan -- who had faced the prospect of life in prison -- has agreed to be interviewed by government investigators without his own legal counsel present , provided that the government gives his attorney reasonable notice . He also agreed not to disclose information about his capture or the conditions surrounding how he and other detainees were treated . Khan , who attended high school in Baltimore , was held for more than three years at secret CIA prisons and `` subjected to an aggressive CIA detention and interrogation program notable for its elaborate planning and ruthless application of torture , '' his lawyers have said , according to court documents . Details of Khan 's torture claims were redacted in the filing , but Khan 's attorneys have said he suffers `` severe physical and psychological trauma from which he is unlikely ever to recover fully '' as a result of his ordeal . Asked earlier about Khan 's claims , then CIA spokesman Paul Gimigliano told CNN , `` CIA 's terrorist interrogation effort has always been small , carefully run , lawful and highly productive . Fewer than 100 hardened terrorists have gone through the program since it began in 2002 , and of those , less than a third required any special methods of questioning . The United States does not conduct or condone torture . '' As part of the agreement reached Wednesday , Khan is also no longer recommended to be housed at the island 's facility 's Camp 7 , where high-value detainees have been kept . `` Majid was tortured prior to his arrival at Guantanamo Bay , but he made a decision despite that , and despite everything that 's transpired in his life , he made a decision to accept responsibility for his actions and to really try to achieve some measure of redemption in his life , '' said J . Wells Dixon , one of Khan 's civilian attorneys . `` The United States government should accept responsibility for what happened to him , just the way that he accepted responsibility today for his actions and the actions of his co-conspirators . '' Another civilian defense attorney for Khan said her client has `` taken a leap of faith . '' `` And he 's taken a leap of faith that this process will work the way that we 're all intending it to work , '' said Katya Jestin . But the overall agreement has prompted controversy over Khan 's treatment and what information can be gleaned after years behind bars . `` Any plea deal and testimony by Majid Khan must be seen in the context of his years of secret , incommunicado detention and torture at the hands of the CIA , and the prospect of trial by an unfair military commissions system , '' said Zachary Katznelson , a senior lawyer for the American Civil Liberties Union who was at Guantanamo to observe the proceedings . The U.S. military said Khan traveled from Baltimore to Karachi , Pakistan , in 2002 to help al Qaeda plan attacks in the United States and elsewhere . The military said Khan conspired with Khalid Sheikh Mohammed , the accused mastermind of the September 11 terrorist attacks , to blow up underground storage tanks in the United States . The government said Khan had also recorded a `` martyr video '' and donned an explosive vest and waited in a mosque where then-Pakistani President Pervez Musharraf was expected . The plan failed when Musharraf did not show up . He also was accused of giving $ 50,000 in al Qaeda funds to a Southeast Asia-based al Qaeda affiliate , which then gave the money to Jemaah Islamiyah to fund the August 2003 bombing of the J.W . Marriott Hotel in Jakarta , Indonesia . That incident killed 11 people and wounded at least 181 others . CNN 's Carol Cratty contributed to this report .
