450 Fifth Street, N.W.
Washington, D.C. 20549
RE: John Hancock Variable Annuity Account I
File Nos. 333-16949 and 811-8696
Dear Commissioners:
This opinion is being furnished with respect to the filing of Post-
Effective Amendment No. 4 under the Securities Act of 1933 (Amendment No. 11
under the Investment Company Act of 1940) of the Form N-4 Registration Statement
of John Hancock Variable Annuity Account I as required by Rule 485 under the
1933 Act.
I have acted as counsel to Registrant for the purpose of preparing this
Post-Effective Amendment which is being filed pursuant to paragraph (b) of Rule
485 and hereby represent to the Commission that in my opinion this
Post-Effective Amendment does not contain disclosures which would render it
ineligible to become effective pursuant to paragraph (b).
We hereby consent to the filing of this opinion with and as a part of
this Post-Effective Amendment to Registrant's Registration Statement with the
Commission.
Very truly yours,
/s/ RONALD J. BOCAGE
Ronald J. Bocage, Esq.
