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

I, Michael E. DeDomenico, certify that:

     1.  I have reviewed this annual report on Form 10-K 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))  and internal
         control  over  financial  reporting  (as defined in Exchange  Act Rules
         13a-15(f) and 15d-15(f)) 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)   Designed such internal control over financial reporting, or caused
              such  internal  control  over  financial  reporting to be designed
              under our supervision,  to provide reasonable  assurance regarding
              the  reliability  of financial  reporting and the  preparation  of
              financial  statements  for external  purposes in  accordance  with
              generally accepted accounting principles;

         c)   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

         d)   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.
