                                 CERTIFICATIONS
                      -------------------------------------

I, Michael E. DeDomenico, certify that:

          1. I have reviewed this quarterly report on Form 10-Q of NuCO2 Inc.;

          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  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  13a-15(e)  and  15d-15(e))  for the
             registrant 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
                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;

             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 (the registrant's fourth
                fiscal  quarter  in the  case  of an  annual  report)  that  has
                materially  affected,  or is  reasonably  likely  to  materially
                affect,   the  registrant's   internal  control  over  financial
                reporting; and

          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  auditors and the audit
             committee  of the  registrant'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 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.
