                                 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.
