                                  CERTIFICATION


I, Martin Schacker, certify that:

          1.       I  have   reviewed  this   quarterly   report  of  Tetragenex
                   Pharmaceuticals,  Inc.  on Form  10-QSB for the period  ended
                   June 30, 2007;

          2.       Based on my  knowledge,  this  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 financial  statements,  and other
                   financial information included in this report, fairly present
                   in all material respects the financial condition,  results of
                   operations and cash flows of the small business issuer as of,
                   and for, the periods presented in this report;

          4.       The small business  issuer's other  certifying  officer and I
                   are responsible for establishing  and maintaining  disclosure
                   controls  and  procedures  (as defined in Exchange  Act Rules
                   13a-15(e) and 15d-15(e))  for the small  business  issuer and
                   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 small  business
                          issuer  including its  consolidated  subsidiaries,  is
                          made  known to us by  others  within  those  entities,
                          particularly during the period in which this quarterly
                          report is being prepared;

                   (b)    Evaluated  the  effectiveness  of the  small  business
                          issuer'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  small
                          business  issuer's  internal  control  over  financial
                          reporting  that  occurred  during  the small  business
                          issuer's  most  recent   fiscal   quarter  (the  small
                          business issuer's fourth fiscal quarter in the case of
                          an annual report) that has materially affected,  or is
                          reasonably  likely  to  material  affect,   the  small
                          business  issuer's  internal  control  over  financial
                          reporting: and

          5.       The small business  issuer's other  certifying  officer and I
                   have  disclosed,  based  on our  most  recent  evaluation  of
                   internal  control  over  financial  reporting,  to the  small
                   business  issuer's  auditors  and the audit  committee of the
                   small  business  issuer's  board  of  directors  (or  persons
                   performing the equivalent functions):


                   (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 small business issuer'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 small business issuer's internal control
                          over financial reporting.
