| 1.   | I      have reviewed this quarterly report on Form 10-Q of Pegasi Energy      Resources Corporation for the quarter ended March 31,  2008; |
|----------------|--------------------------------------------------------------------------------------------------------------------------------------------|

| 2.   | Based      on my knowledge, this quarterly report does not contain any untrue      statement of a material fact or omit to state a material fact necessary to      make the statements made, in light of the circumstances under which such      statements were made, not misleading with respect to the period covered by      this report; |
|----------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 3.   | Based      on my knowledge, the consolidated financial statements, and other      financial information included in this report, fairly present in all      material respects the consolidated financial condition, results of      operations and cash flows of the registrant as of, and for, the periods      presented in this report; |
|----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 4.   | The      registrant’s other certifying officer and I are responsible for      establishing and maintaining disclosure controls and procedures (as      defined in Exchange Act Rules 1 3a-1 5(e) and 1 5d-1 5(e)) for the      registrant and we have: |
|----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| a.   | Designed      such disclosure controls and procedures, or caused such disclosure      controls and procedures to be designed under our supervision, to ensure      that material information relating to the registrant, including its      consolidated subsidiaries, is made known to us by others within those      entities, particularly during the period in which this report is being      prepared; and |
|----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| b.   | Evaluated      the effectiveness of the registrant’s disclosure controls and procedures      and presented in this report our conclusions about the effectiveness of      the disclosure controls and procedures, as of the end of the period      covered by this report based on such evaluation;  and |
|----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| c.   | Disclosed in this report any change in the registrant’s      internal control over financial reporting that occurred during the      registrant’s most recent fiscal quarter that has materially affected, or      is reasonably likely to materially affect, the registrant’s internal      control over financial reporting; |
|----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 5.   | The registrant’s other certifying officer and I have      disclosed, based on our most recent evaluation of internal control over      financial reporting, to the registrant’s independent registered public      accounting firm and the audit committee of the registrant’s board of      directors (or persons performing the equivalent  function): |
|----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| a.   | All      significant deficiencies and material weaknesses in the design or      operation of internal control over financial reporting which are      reasonably likely to adversely affect the registrant’s ability to record,      process, summarize and report financial information;  and |
|----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| b.   | Any      fraud, whether or not material, that involves management or other      employees who have a significant role in the registrant’s internal control      over financial reporting. |
