     Re:  Financing facilities for the merger of Vermont Pure Holdings, Ltd.
          and Crystal Rock Spring Water Company

Dear Peter and Tim:

     This is the second amendment to the Commitment Letter Dated April 14, 2000
regarding the above transaction. The date that the loans must close by is
extended from August 31, 2000 to not later than October 31, 2000. Thus the
second paragraph above the signature line shall now read:

     "If for any reason the Loans do not close by October 31, 2000, time being
of the essence, this Commitment shall lapse and shall be of no further force or
effect unless the time for closing is extended to a date certain in writing by
the Bank."

     If you have any questions, please do not hesitate to contact me.

                                             Very truly yours,

                                             WEBSTER BANK

Should Ball lower the gram weight of their containers, the price for such lower
gram weight containers shall nevertheless remain the same due to the fact that
all savings have already been passed on to Vermont Pure in Z-H's pricing.

     D. DUNNAGE: All pallets, frames and tier sheets will be memo billed to
Vermont Pure and rectified on a quarterly basis. Vermont Pure shall be
responsible for the replacement of those pallets, frames and tier sheets lost or
damaged due to Vermont Pure's negligence.

     2. QUALITY: Z-H agrees to supply Vermont Pure quality bottles that are
consistent with industry standards. If Z-H fails to supply Vermont Pure with
quality bottles, Vermont Pure will give Z-H notice in writing, detailing the
precise nature of the alleged lack of quality. Z-H will then have a thirty (30)
day period in which to cure the alleged lack of quality. If the bottles still
fail to meet industry standards at the conclusion of thirty (30) days, Vermont
Pure will be free to purchase from an alternative supplier.

     3. SERVICE: Vermont Pure agrees to supply in writing to Z-H a 90-day
rolling forecast of its requirements, updated the first week of each month. Z-H
agrees to supply Vermont Pure bottles on a timely basis consistent with Vermont
Pure's requirements as reflected in the 90-day forecast. Z-H will use its best
efforts to meet requests for additional bottles in excess of the 90-day
forecast, but cannot guarantee supply of the excess bottle. Z-H will utilize any
and all locations necessary to meet Vermont Pure's needs at no additional
expense to Vermont Pure.

     4. EFFECTIVENESS AND TERM: This agreement will be effective for 36 months
commencing January 1, 1999. Volume is to be a minimum of 250,000,000 bottles
over the length of the contract with a +/- of 5%. Should Vermont require bottles
in excess of the 262,500,000, Z-H will have 30 days from the time of
notification to accept or decline the increased volume. Should ZH decline,
Vermont would be free to secure the additional bottles on the open market. At
the end of the term, Vermont Pure shall give Z-H the right to match any bona
fide written opportunity involving Vermont Pure and their P.E.T. requirements,
in which event Z-H shall continue to be the exclusive supplier of PET bottles,
consistent with such terms.

     5. PAYMENT: Payment terms will be net 30 days. Interest will be charged at
Wall Street Journal "prime rate of interest" plus two (2%) percent per annum on
all invoices over thirty (30) days. Shipments from Z-H will stop on the 40th day
until all invoices are current.

     6. FORCE MAJEURE: If either party to this Agreement is unable to perform
its obligations under this Agreement as a consequence of a delay or failure from
any cause or event beyond the control of such party, including but not limited
to war, riots, acts of God or public enemy, fire, explosion, flood, earthquake,
strikes, lockouts or other labor disturbance, embargo, actions or any
governmental authority, such party shall be excused from the performance of such
obligations for the period of and to the extent of any such cause or event. On
the cessation of any event of force majeure as defined above, the disabled party
shall notify the party whose performance has not been excused of such cessation
or termination, and the disabled party's performance under this Agreement shall
recommence subject to an allowance for a reasonable amount of time to rebuild or
repair any damage or injury caused by the event, if any, which is necessary to
the party's performance. If cessation hereunder persists for a period of time
greater than eight (8) weeks, then this Agreement will terminate. Any cessation
hereunder will not extend the term of the contract.

     7. CONFIDENTIALITY: The parties shall use reasonable efforts to cause their
respective employees, agents and other representatives to hold, in confidence,
all confidential information (as hereinafter defined), and the parties shall use
efforts to ensure that any other person having access to the Confidential
Information through time shall not disclose the same to any person except in
connection with this Agreement and otherwise as may be reasonably necessary to
carry out this Agreement and the transactions contemplated hereby or to comply
with applicable law. For purposes hereof, "Confidential Information" means all
information of any kind (including, without limitation, sales and promotional
results) obtained directly or indirectly from either party's business, except
information which constitutes readily ascertainable public information.
"Confidential Information" shall not include any information which (i) is
generally available to the public as of the date of this Agreement, or (ii)
becomes generally available to the public after the date of this Agreement,
provided that such public disclosure did not result, directly or indirectly,
from any act, omission or fault of either of the parties to this agreement or
any of their agents with respect to such information.

     8. ASSIGNMENT: This Agreement and all of the provisions hereof shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns. Neither party shall assign this Agreement
without the prior written consent of the other party, assign (i) this Agreement
to such party's subsidiary or affiliate, or (ii) such party's rights, but not
obligations, to any lender of such party. Subject to obtaining the written
consent of Z-H, Vermont Pure agrees that in the event Vermont Pure conveys the
bulk of its business to a third party (whether pursuant to an asset sale, stock
sale or otherwise) during the term of this Agreement, Vermont Pure shall cause
the purchaser of such assets, stock or otherwise, as the case may be, to assume
the obligations of Vermont Pure under this Agreement.
