| | 1. | I have
  reviewed this quarterly report on Form 10-Q of Ridgewood Energy V Fund, LLC;                                                                                                                                                                                                                                                                 
| |    |                                                                                                                                                                                                                                                                                                                                                       
| | 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;                                    
| |    |

  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(s) 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 Rule s 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(s) 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.
