Explanatory Note

Oxygen Biotherapeutics, Inc. (OBI or Oxygen Biotherapeutics) is filing this Amendment No. 1 (the Amendment) to its Annual Report on Form 10-K for the fiscal year
ended April 30, 2009 (the Original Annual Report), as filed with the Securities and Exchange Commission (the SEC) on August 12, 2009. OBI is filing this Amendment in response to certain comments made by the staff of
the SEC with respect to the Original Annual Report. The purpose of this Amendment is to amend and restate Item 9A(T) to report on managements conclusion regarding the effectiveness of OBIs disclosure controls and procedures and
Item 15 to add exhibit 10.28, which was inadvertently omitted in the original exhibit listing and filing, and to fix incorrect cross references in the exhibit listing. OBI is filing herewith currently dated certifications in Exhibits 31.3 and
31.4. The remainder of OBIs Annual Report on Form 10-K remains unchanged and is not reproduced in this Amendment No. 1.

This
report speaks as of the original filing date of the Original Annual Report and has not been updated to reflect events occurring subsequent to August 12, 2009. Accordingly, in conjunction with reading this Form 10-K/A, you should also read all
other filings that OBI has made with the SEC since the date of the original filing.

Part II

ITEM 9A(T)CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the
Exchange Act), are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in rules and forms
adopted by the SEC, and that such information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosures.

Management, with the participation of the Chief Executive Officer and the Chief Financial Officer, has evaluated the effectiveness of our disclosure
controls and procedures as of the end of the period covered by this Form 10-K. Based on such evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that, as of April 30, 2009, our disclosure controls and procedures
were not effective. Our disclosure controls and procedures were not effective because of the material weaknesses described below under Managements annual report on internal control over financial reporting, which are in
the process of being remediated as described below under Management Plan to Remediate Material Weaknesses.

Changes in Internal
Controls

In April 2009, OBI created the position of Accounting Manager and staffed this position with an experienced
Certified Public Accountant. The addition of this additional accounting professional allowed OBI to segregate duties in the accounting department and this enabled OBI to enhance the control environment. Also during the fourth quarter of fiscal year
ended April 30, 2009 we increased the size of our board and added a board member that meets the definition of independent as defined in Rule 5605(a)(2) of the Nasdaq Listing Rules, and added a non-director consultant to our audit
committee that meets the definition of a finance expert as outlined under item 407(d) of Regulation S-K.

Management Plan to
Remediate Material Weaknesses

In the first six months of fiscal year 2010, management is pursuing the implementation of
corrective measures to address the material weaknesses described below. These measures, outlined below, are intended both to address the identified material weaknesses and to enhance our overall financial control environment.



| |  |  | Implement a process for internal control testing as prescribed by the Sarbanes-Oxley Act of 2002. As a result of this internal control testing we will
identify the remediation actions needed to allow us to implement an effective system of internal controls over financial reporting. Currently we are working on reviewing and revamping the policies and procedures.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Implement remediation actions to allow for good entity level controls. In particular, we are working on a detailed entity level control matrix, and
engaged the overall participation of the board of directors.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We will evaluate the need for us to create a Chief Audit Executive function.
| | - |  | ----------------------------------------------------------------------------



| |  |  | We will move all accounting function to one centralized location.
| | - |  | -----------------------------------------------------------------

We believe the remediation measures described above will remediate the material weaknesses we have identified and strengthen our internal
control over financial reporting. We are committed to continuing to improve our internal control processes and will continue to diligently and vigorously review our financial reporting controls and procedures. As we continue to evaluate and work to
improve our internal control over financial reporting, we may determine to take additional measures to address control deficiencies or determine to modify, or in appropriate circumstances not to complete, certain of the remediation measures
described above.

Managements annual report on internal control over financial reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over
financial reporting, as defined in rules promulgated under the Exchange Act, is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and affected by our Board of Directors, management and other
personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Internal control over financial reporting includes those policies
and procedures that:



| |  |  | pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and
that our receipts and expenditures are being made only in accordance with authorizations of our management and our Board of Directors; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a
material effect on our financial statements.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Internal control over financial reporting cannot provide
absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and
breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected
on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process, and it is possible to design into the process safeguards to reduce, though not eliminate, this
risk.

Our management assessed the effectiveness of our internal control over financial reporting as of April 30, 2009.
In making its assessment, management used the criteria established inInternal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its assessment,
management has concluded that we had certain control deficiencies described below that constituted material weaknesses in our internal controls over financial reporting. As a result, our internal control over financial reporting was not effective as
of April 30, 2009.

A material weakness is defined under SEC rules as a deficiency, or a combination of
deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of a companys annual or interim financial statements will not be prevented or detected on a timely basis by the
companys internal controls. As a result of managements review of the investigation issues and results, and other internal reviews and evaluations that were completed after the end of fiscal year 2009 related to the preparation of
managements report on internal controls over financial reporting required for this annual report on Form 10-K, management concluded that we had material weaknesses in our control environment and financial reporting process consisting of the
following:



| |  |  | We have not always consistently maintained final, complete and executed copies of significant contracts, including financing agreements, warrant and
option agreements, and note agreements. We rely on a very small staff, and have been a party to numerous complex financing transactions that required significant changes to terms, which were not clearly and effectively processed and recorded as they
occurred.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Because of turnover in the accounting function during the fiscal year , we did not maintain a sufficient amount of knowledge of US Generally Accepted
Accounting Principles, did not measure board committee performance against established charters, have not implemented an anonymous whistle-blower process, did not strengthen entity level controls, and did not utilize a formal financial reporting
close process that ensured sufficient levels of review of all key financial statement reconciliations, significant judgment estimates and period end financial statements.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We do not believe the material weaknesses described above caused any meaningful or significant misreporting of our financial condition and
results of operations for the fiscal year ended April 30, 2009. We note, however, that the material weaknesses are in our control environment and financial reporting process and could



---

negatively impact our operating controls and procedures in future periods if they remain unaddressed by management. To address the material weakness described above, we have made significant
changes to our control environment and financial reporting process. The changes are outlined below:



| |  |  | We now process all transactions from a centralized location
| | - |  | -----------------------------------------------------------



| |  |  | We now have two experienced Certified Public Accountants on staff
| | - |  | -----------------------------------------------------------------



| |  |  | We now require approval of all accounts payable invoices by a C level executive
| | - |  | ---------------------------------------------------------------------------------



| |  |  | We now store all significant contracts, including financial agreements, warrants and option agreements, and note agreements in a centralized location
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------

This annual report does not include an attestation report of our registered public accounting firm
regarding internal control over financial reporting. Managements report was not subject to attestation by our registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the Company to
provide only managements report in this annual report.
