                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                          OVATION PRODUCTS CORPORATION

WARRANT NO. [o]                                                       [o] SHARES

      FOR VALUE RECEIVED, Ovation Products Corporation (the "Company"), a
Delaware corporation, hereby certifies that [Name of Holder] with [PRINCIPAL
OFFICES/RESIDENCE] at [o], or his assigns, is entitled to purchase from the
Company, at any time or from time to time, a total of [o] ([o]) fully paid and
nonassessable shares of the Common Stock, $1.00 par value per share, of the
Company for an aggregate purchase price of $[o] (computed on the basis of $6.00
per share). Hereinafter, (i) said Common Stock, together with any other equity
securities which may be issued by the Company with respect thereto or in
substitution therefor, is referred to as the "Common Stock"; (ii) the shares of
the Common Stock purchasable hereunder are referred to as the "Warrant Shares";
(iii) the aggregate purchase price payable hereunder for the Warrant Shares is
referred to as the "Aggregate Warrant Price"; (iv) the price payable hereunder
for each of the Warrant Shares is referred to as the "Per Share Warrant Price";
(v) this Warrant, and all warrants hereafter issued in exchange or substitution
for this Warrant are referred to as the "Warrant"; and (vi) the holder of this
Warrant is referred to as the "Holder". The Per Share Warrant Price is subject
to adjustment as hereinafter provided. In the event of any such adjustment, the
number of Warrant Shares shall be adjusted by dividing the Aggregate Warrant
Price by the Per Share Warrant Price in effect immediately after such
adjustment.

      1. EXERCISE OF WARRANT. This Warrant may be exercised, in whole at any
time or in part from time to time, commencing on the date hereof, and prior to
5:00 P.M., Eastern Standard Time, on June [o] 2010, the Holder (with the
subscription form at the end hereof duly executed) at the address set forth in
Subsection 9(a) hereof, together with proper payment of the Aggregate Warrant
Price, or the proportionate part thereof if this Warrant is exercised in part.
Payment for Warrant Shares shall be made, at the election of the Holder, (i) by
set-offs against amounts due to the Holder under any promissory notes issued by
the Company (in which event such note(s) shall be delivered to the Company at
the time of exercise), or (ii) certified or official bank check payable to the
order of the Company. If this Warrant is exercised in part, this Warrant must be


                                       1
<PAGE>

exercised for a minimum of 25 shares of the Common Stock, and the Holder is
entitled to receive a new Warrant covering the number of Warrant Shares in
respect of which this Warrant has not been exercised and setting forth the
proportionate part of the Aggregate Warrant Price applicable to such Warrant
Shares. Upon such surrender of this Warrant, the Company will (a) issue a
certificate or certificates in the name of the Holder for the largest number of
whole shares of the Common Stock to which the Holder shall be entitled and, if
this Warrant is exercised in whole, in lieu of any fractional share of the
Common Stock to which the Holder shall be entitled, cash equal to the fair value
of such fractional share (determined in such reasonable manner as the Board of
Directors of the Company shall determine); (b) deliver the proportionate part
thereof if this Warrant is exercised in part, pursuant to the provisions of the
Warrant and (c) deliver a replacement promissory note representing the
unsatisfied portion of any promissory note delivered in payment for the Warrant
Shares.

      2. RESERVATION WARRANT SHARES. The Company agrees that, prior to the
expiration of this Warrant, the Company will at all times have authorized and in
reserve, and will keep available, solely for issuance or delivery upon the
exercise of this Warrant, the shares of the Common Stock as from time to time
shall be receivable upon the exercise of this Warrant.

      3. ADJUSTMENT OF PURCHASE PRICE.

            (a)   Stock Splits, Stock Dividends and Reverse Splits. In case the
                  Company shall at any time divide the outstanding shares of its
                  Common Stock into a greater number of shares (whether pursuant
                  to a stock split, stock dividend or otherwise), the Purchase
                  Price in effect immediately prior to such division shall be
                  proportionately reduced and the number of Warrant Shares shall
                  be proportionately increased, and conversely, in the case the
                  outstanding shares of the Company's Common Stock shall be
                  combined into a smaller number of shares, the Purchase Price
                  in effect immediately prior to such combination shall be
                  proportionately increased and the number of Warrant Shares
                  proportionately reduced.

            (b)   Reorganization, Consolidation, Merger or Sale of Assets. If
                  any capital reorganization or reclassification of the capital
                  stock of the Company, or consolidation or merger of the
                  Company with another corporation, or the sale of all or
                  substantially all of its assets to another corporation shall
                  be effected in such a way that holders of shares of the
                  Company's Common Stock shall be entitled to receive stock,
                  securities or assets, with respect to or in exchange for such
                  shares, then, as a condition of such reorganization,
                  reclassification, consolidation, merger or sale, the holder of
                  this Warrant shall have the right to purchase and receive upon
                  the basis and upon the terms and conditions specified in this
                  Warrant and in addition to or in lieu of, as the case may be,
                  the shares of Common Stock immediately theretofore purchasable
                  and receivable upon exercise of the rights represented hereby,
                  such shares of stock, other securities or assets as would have


                                       2
<PAGE>

                  been issued or delivered to the holder of this Warrant if such
                  holder had exercised this Warrant and had received such shares
                  of Common Stock prior to such reorganization,
                  reclassification, consolidation, merger or sale. The Company
                  shall not effect any such consolidation, merger or sale,
                  unless prior to the consummation thereof the successor
                  corporation (if other than the Company) resulting from such
                  consolidation or merger or the corporation purchasing such
                  assets shall assume by written instrument executed and mailed
                  to the registered holder of the Warrant at the last address of
                  such holder appearing on the books of the Company the
                  obligation to deliver to such holder such shares of stock,
                  securities or assets as, in accordance with the foregoing
                  provisions, such holders may be entitled to purchase.

            (c)   Other Actions. The issuance of additional shares of additional
                  capital shares of the Company to persons other than the
                  Warrant holder in a manner not discussed in this section 3
                  shall not result in any adjustment in the Purchase Price or
                  increase in the number of shares subject to this Warrant.

      4. FULLY PAID STOCK; TAXES. The Company agrees that the shares of stock
represented by each and every certificate for Warrant Shares delivered on the
exercise of this Warrant shall, at the time of such delivery, be validly issued
and outstanding, fully paid and non-assessable, and not subject to preemptive
rights, and the Company will take all such actions as may be necessary to assure
that the par value or stated value, if any, per share of the Common Stock is at
all times equal to or less than the then Per Share Warrant Price. The Company
further covenants and agrees that it will pay, when due and payable, any and all
Federal and state stamp, original issue or similar (but not income) taxes that
may be payable in respect of the issue of any Warrant Share or certificate
therefor.

      5. Transfer.

            (a)   Securities Laws. Neither this Warrant nor the Warrant Shares
                  issuable upon the exercise hereof have been registered under
                  the Securities Act of 1933, as amended (the "Securities Act")
                  or under any state securities laws and unless so registered
                  may not be transferred, sold, pledged, hypothecated or
                  otherwise disposed of unless an exemption from such
                  registration is available. In the event Holder desires to
                  transfer this Warrant or any of the Warrant Shares issued, the
                  Holder must give the Company prior written notice of such
                  proposed transfer including the name and address of the
                  proposed transferee. Such transfer may be made only either (i)
                  upon publication by the Securities and Exchange Commission
                  (the "Commission") of a ruling, interpretation, opinion or "no
                  action letter" based upon facts presented to said Commission,
                  or (ii) upon receipt by the Company of an opinion of counsel
                  to the Warrant holder satisfactory in form and content to the
                  Company and its counsel in either case to the effect that the
                  proposed transfer will not violate the provisions of the
                  Securities Act, the Securities Exchange Act of 1934, as


                                       3
<PAGE>

                  amended, or the rules and regulations promulgated under either
                  such act, or in the case of clause (ii) above, to the effect
                  that the Warrant or Warrant Shares to be sold or transferred
                  has been registered under the Securities Act, as amended, and
                  that there is in effect a current prospectus meeting the
                  requirements of Subsection 10(a) of the Securities Act, which
                  is being or will be delivered to the purchaser or transferee
                  at or prior to the time of delivery of the certificates
                  evidencing the Warrant or Warrant Stock to be sold or
                  transferred.

            (b)   Conditions to Transfer. Prior to any such proposed transfer,
                  and as a condition thereto, if such transfer is not made
                  pursuant to an effective registration statement under the
                  Securities Act, the Holder will, if requested by the Company,
                  deliver to the Company (i) a representation of investment
                  intent signed by the proposed transferee, (ii) an agreement by
                  such transferee to placing of the restrictive legend
                  substantially in the form set forth herein on the certificate
                  or certificates representing the securities acquired by such
                  transferee, (iii) an agreement by such transferee that the
                  Company may place a "stop transfer order" with its transfer
                  agent or registrar, (iv) an agreement by the transferee to
                  indemnify the Company to the same extent as set forth in the
                  next succeeding paragraph, and (v) other documentation,
                  certificates or instruments reasonably requested by the
                  Company or its counsel.

            (c)   Indemnity. The Holder acknowledges that the Holder understands
                  the meaning and legal consequences of this Section 5, and the
                  Holder hereby agrees to indemnify and hold harmless the
                  Company, its representatives and each officer and director
                  thereof from and against any and all loss, damage or liability
                  (including all attorneys fees, and other fees, costs and
                  expenses incurred in enforcing this indemnity provision) due
                  to or arising out of (a) the inaccuracy of any representation
                  or the breach of any warranty of the Holder contained in, or
                  any other breach of, this Warrant or in any other instruments,
                  documents or certificates entered into in connection with or
                  pursuant to the terms of this Warrant, (b) any transfer of the
                  Warrant or any of the Warrant Shares in violation of the
                  Securities Act, the Securities Exchange Act of 1934, as
                  amended, or the rules and regulations promulgated under either
                  of such acts, (c) any transfer of the Warrant or any of the
                  Warrant Shares not in accordance with this Warrant or (d) any
                  untrue statement or omission to state any material fact in
                  connection with the representations of investment intent or
                  with respect to the facts and representations or in any other
                  instruments, documents or certificates entered into in
                  connection with or pursuant to the terms of the Warrant
                  supplied by the Holder to counsel to the Company upon which
                  its opinion as to a proposed transfer shall have been based.

            (d)   Transfer. Except as restricted hereby, this Warrant and the
                  Warrant Shares issued may be transferred by the Holder in
                  whole or in part at any time or from time to time. Upon
                  surrender of this Warrant to the Company or at the office of
                  its stock transfer agent, if any, with assignment
                  documentation duly executed and funds sufficient to pay any
                  transfer tax, and upon compliance with the foregoing


                                       4
<PAGE>

                  provisions, the Company shall, without charge, execute and
                  deliver a new Warrant in the name of the assignee named in
                  such instrument of assignment, and this Warrant shall promptly
                  be canceled. Any assignment, transfer, pledge, hypothecation
                  or other disposition of this Warrant attempted contrary to the
                  provisions of this Warrant or subsequent agreement to which
                  this Warrant is subject, or any levy of execution, attachment
                  or other process attempted upon the Warrant, shall be null and
                  void and without effect.

            (e)   Legend and Stop Transfer Orders. Unless the Warrant Shares
                  have been registered under the Securities Act, upon exercise
                  of any part of the Warrant and the issuance of any Warrant
                  Shares, the Company shall, or the Company shall instruct its
                  transfer agent, to enter stop transfer orders with respect to
                  such shares, and all certificates representing Warrant Shares
                  shall bear on the face thereof substantially the following
                  legend, insofar as is consistent with Delaware law:

                        "The shares of Common Stock represented by this
                        certificate have not been registered under the
                        Securities Act of 1933 (the "Act"), as amended, and may
                        not be sold, offered for sale, assigned, transferred or
                        otherwise disposed of unless registered pursuant to the
                        provisions of the Act or an opinion of counsel to the
                        holder satisfactory to the Company and its counsel is
                        obtained stating that such disposition is in compliance
                        with an available exemption from such required
                        registration."

      6. Registration Rights.

            (a)   Incidental Registration. If the Company at any time proposes
                  for any reason to register any of its securities under the
                  Securities Act (other than pursuant to a registration
                  statement on Forms S-4, S-8, S-14 or S-15 or similar or
                  successor form), it shall each such time promptly give written
                  notice to all holders of outstanding Registrable Shares (as
                  defined below) of its intention so to do, and, upon the
                  written request, given within 20 days after receipt of any
                  such notice, of the holder of any such Registrable Shares to
                  register any Registrable Shares (which request shall specify
                  the Registrable Shares intended to be sold or disposed of by
                  such holders and shall state the intended method of
                  disposition of such Registrable Shares by the prospective
                  seller), the Company shall use its commercially reasonable
                  efforts to cause all such Registrable Shares, to be registered
                  under the Securities Act promptly upon receipt of the written
                  request of such holders for such registration, all to the
                  extent requisite to permit the sale or other disposition (in
                  accordance with the intended methods thereof, as aforesaid) by
                  the prospective seller or sellers of the Registrable Shares so
                  registered. In the event that the proposed registration by the
                  Company is, in whole or in part, an underwritten public
                  offering of securities of the Company, any request pursuant to


                                       5
<PAGE>

                  this Section 6 to register Registrable Shares may specify that
                  such shares are to be included in the underwriting (i) on the
                  same terms and conditions as the shares of Common Stock, if
                  any, otherwise being sold through underwriters under such
                  registration, or (ii) on terms and conditions comparable to
                  those normally applicable to offerings of common stock in
                  reasonably similar circumstances in the event that no shares
                  of Common Stock other than Registrable Shares are being sold
                  through underwriters under such registration; provided,
                  however, that (A) if the managing underwriter determines and
                  advises in writing that the inclusion of all Registrable
                  Shares proposed to be included in the underwritten public
                  offering and other issued and outstanding shares of Common
                  Stock proposed to be included therein by persons other than
                  holders of Registrable Shares (the "Other Shares") would
                  interfere with the successful marketing (including pricing) of
                  such securities, then the number of Registrable Shares and
                  Other Shares to be included in such underwritten public
                  offering shall be reduced first, pro rata among the holders of
                  Other Shares, and second, if necessary, pro rata among the
                  holders of Registrable Shares based upon the number of
                  Registrable Shares and shares of Common Stock requested by the
                  holders thereof to be registered in such underwritten public
                  offering and (B) in each case those shares of Common Stock
                  which are excluded from the underwritten public offering shall
                  be withheld from the market by the holders thereof for a
                  period, not to exceed 180 days, which the managing underwriter
                  reasonably determines as necessary in order to effect the
                  underwritten public offering.

            (b)   Preparation and Filing. If and whenever the Company is under
                  an obligation pursuant to the provisions of this Section 6 to
                  use its commercially reasonable efforts to effect the
                  registration of any Registrable Shares, the Company shall, as
                  expeditiously as practicable:

                  (i)   prepare and file with the Commission a registration
                        statement with respect to such securities and use its
                        commercially reasonable efforts to cause such
                        registration statement to become and remain effective in
                        accordance with Section 6(b)(ii);

                  (ii)  prepare and file with the Commission such amendments and
                        supplements to such registration statements and the
                        prospectus used in connection therewith as may be
                        necessary to keep such registration statement effective
                        for at least six months (or such shorter period during
                        which all such Registrable Shares registered on such
                        registration statement have been sold) and to comply
                        with the provisions of the Securities Act with respect
                        to the sale or other disposition of all Registrable
                        Shares covered by such registration statement;

                        including a preliminary prospectus, in conformity with
                        the requirements of the Securities Act, and such other
                        documents as such seller may reasonably request in order

                        Company shall not be required to consent to general
                        service of process for all purposes in any jurisdiction

                  (v)   notify each seller of Registrable Shares covered by such
                        registration statement, at any time when a prospectus
                        relating thereto covered by such registration statement
                        is required to be delivered under the Securities Act
                        within the appropriate period mentioned in Section 6(c),

                        material fact or omits to state a material fact required
                        to be stated therein or necessary to make the statements

                        and furnish to such seller a reasonable number of copies
                        of a supplement to or an amendment of such prospectus as
                        may be necessary so that, as thereafter delivered to the
                        purchasers of such shares, such prospectus shall not
                        include an untrue statement of a material fact or omit
                        to state a material fact required to be stated therein
                        or necessary to make the statements therein not
                        misleading in the light of the circumstances then
                        existing; and

                  (vi)  furnish, at the request of any holder or holders
                        requesting registration of Registrable Shares pursuant
                        to this Section 6, on the date that such Registrable
                        Shares are delivered to the underwriters for sale in
                        connection with a registration described in this Section
                        6, if such securities are being sold through
                        underwriters, or, if such securities are not being sold
                        through underwriters, on the date that the registration
                        statement with respect to such securities becomes
                        effective, (A) an opinion, dated such date, of the
                        counsel representing the Company for the purposes of
                        such registration, in form and substance as is
                        customarily given to underwriters in an underwritten
                        public offering, addressed to the underwriters, if any,
                        and to the holder or holders making such request; and
                        (B) a letter dated such date, from the independent

            (c)   Market Stand-Off Agreement. Each holder of Registrable Shares
                  agrees, if requested by the Company and an underwriter of
                  Common Stock or other securities of the Company, not to sell,
                  assign, donate, pledge, encumber, hypothecate, grant an option
                  to, or otherwise transfer or dispose of, whether in privately
                  negotiated or open market transactions, any Common Stock or
                  other securities of the Company held by it during the 180-day
                  period following the effective date of a registration
                  statement filed pursuant to the Public Offering (as defined
                  below), provided that:

                  (i)   Such agreement shall apply only to the initial Public
                        Offering; and

                  (ii)  All other holders of Registrable Shares, any other
                        security holders whose securities are included in such
                        registration statement, and all officers, directors and
                        key employees of the Company shall also enter into
                        similar agreements.

                  Such agreement shall be in writing in form and substance
                  satisfactory to the Company and such underwriter. The Company
                  may impose stop-transfer instructions with respect to the
                  shares subject to the foregoing restrictions until the end of
                  said 180-day period.

            (d)   Expenses. In the case of a registration hereof for the account
                  of the Company in which the Company is receiving proceeds from
                  the sale of its equity securities, the Company shall bear all
                  costs and expenses of each such registration, including, but
                  not limited to, printing, legal and accounting fees and
                  expenses, Securities and Exchange Commission and NASD filing
                  fees and "Blue Sky" fees and expenses; provided, however, that
                  the Company shall have no obligation to pay or otherwise bear
                  any portion of the underwriters' commissions or discounts
                  attributable to the Registrable Shares being offered and sold
                  by the holders of Registrable Shares, or the fees and expenses
                  of any counsel for the selling holders of Registrable Shares
                  in connection with the registration of the Registrable Shares.

            (e)   Additional Covenants Concerning Sale of Shares.

                  (i)   If permitted by applicable law and regulation, the
                        Company, at the request of the holder of Registrable
                        Shares, shall file such amendments and/or supplements to
                        such registration statement necessary to take such other
                        steps as may be required to maintain such registration

                        statement in effect, and to keep the information therein
                        current, so long as any of the Registrable Shares
                        included therein remain unsold. In connection with any
                        registration statement referred to in this Section 6,
                        the Company shall furnish to the holder of Registrable
                        Shares (or to any broker or other person at its request)
                        a reasonable number of copies of such registration
                        statement, each amendment and supplement thereto and
                        each document included therein, and such number of
                        copies of the then current prospectus included therein
                        as either the holder of Registrable Shares or its
                        brokers may from time to time reasonably request.

                  (ii)  In connection with any registration statement referred
                        to in this Section 6 of this Agreement, the holder of
                        Registrable Shares will furnish to the Company such
                        information as the Company may reasonably require from
                        such holder for inclusion in the registration statement
                        (and the prospectus included therein).

                  (iii) The Company's obligations under this Section 6 shall be
                        conditioned upon each shareholder (including the Holder
                        of Registrable Shares) whose Shares are being registered
                        and any underwriter participating in such public
                        offering executing and delivering to the Company an
                        appropriate agreement, in form satisfactory to counsel
                        for the Company, that he will comply with all
                        anti-stabilization, manipulation, and similar provisions
                        of Section 10 of the Securities Exchange Act of 1934, as
                        amended, and any rules promulgated thereunder and will
                        furnish to the Company information about sales made in
                        such public offering.

            (f)   Blue Sky Provisions. The Company, at its expense, shall cause
                  all of the Registrable Shares included in a registration
                  statement referred to in this Section 6 to be qualified under
                  the laws of such reasonable number of jurisdictions as the
                  holder of Registrable Shares (provided that the Company shall
                  not be required to (i) qualify generally to do business in any
                  jurisdiction where it would not otherwise be required to
                  qualify but for this subparagraph, (ii) subject itself to
                  taxation in any such jurisdiction or (iii) consent to general
                  service of process in any such jurisdiction), or the managing
                  underwriter named therein, may designate, and the Company will
                  continue such qualification in effect so long as may be
                  necessary to comply with all applicable laws regulating sales
                  of securities.

            (g)   Advising the Holder of Registrable Shares. In connection with
                  any registration statement referred to in this Section 6, the
                  Company will promptly advise each holder of Registrable Shares
                  and confirm such advice in writing (i) when the registration
                  statement has become effective, (ii) when any post-effective
                  amendment to the registration statement becomes effective, and
                  (iii) of any request by the SEC for any amendment or
                  supplement to the registration statement or prospectus or for
                  additional information.

                  If at any time the SEC should institute or threaten to
                  institute any proceeding for the purposes of issuing, or
                  should issue, a stop order suspending the effectiveness of the
                  registration statement, the Company will promptly notify the
                  holder of Registrable Shares, and will use its commercially
                  reasonable efforts to prevent the issuance of any such stop
                  order or to obtain the withdrawal thereof as soon as possible;
                  and the Company will advise such holder of Registrable Shares
                  promptly of any order or communication of any public board or
                  body addressed to the Company suspending or threatening to
                  suspend the qualification of any Registrable Shares for sale
                  in any jurisdiction.

            (h)   Indemnification.

                  (i)   With respect to the registration rights described in
                        this Section 6, the Company hereby agrees to indemnify,
                        hold harmless and defend each holder of Registrable
                        Shares and each person, if any, who is deemed a
                        controlling person of such holder of Registrable Shares
                        within the meaning of the Securities Act, against any
                        and all losses, claims, damages or liabilities
                        (including legal and other expenses incurred in
                        investigating and defending against the same), to which
                        they, or any of them, may become subject under the
                        Securities Act or other statute or common law, arising
                        out of or based upon:

                        (A)   any alleged untrue statement of a material fact
                              contained in any registration statement,
                              preliminary prospectus or prospectus included
                              therein, any amendment thereof of supplement
                              thereto; or

                        (B)   the alleged omission to state therein a material
                              fact required to be stated therein or necessary to
                              make the statements contained therein not
                              misleading; provided, however, that the indemnity
                              contained in this Subsection (g) shall not apply
                              to any such alleged untrue statement or omission
                              made in reliance upon and in conformity with
                              information furnished in writing to the Company by
                              or on behalf of the Holder of Registrable Shares.
                              The holder of Registrable Shares agrees that as
                              soon as practicable, but in any event within
                              forty-five (45) days, after the receipt of notice
                              of any claim or action against it in respect of
                              which indemnity may be sought from the Company
                              hereunder, to notify the Company thereof in
                              writing, and the Company shall assume the defense
                              of such claim or action (and the cost thereof) by
                              counsel of its own choosing, who shall be
                              reasonably satisfactory to the holder of
                              Registrable Shares.

                  (ii)  Each selling holder of Registrable Shares shall agree to
                        indemnify, hold harmless and defend the Company, its
                        directors and officers, and each person, if any, who is
                        deemed a controlling person of the Company with the
                        meaning of the Securities Act, against any and all
                        losses, claims, damages or liabilities, including legal
                        or other expenses incurred in investigating and
                        defending against the same, to which they or any of them
                        may become subject under the Securities Act or other
                        statute or common law, arising out of or based upon:

                        (A)   any alleged untrue statement of a material fact
                              contained in any such registration statement, or
                              prospectus or preliminary prospectus included
                              therein, or any amendment thereof or supplement
                              thereto, but only to the extent, that such untrue
                              statement or alleged untrue statement was made in
                              the registration statement or any amendment or
                              supplement thereto, in reliance upon and in
                              conformity with written information furnished to
                              the Company by or on behalf of any holder of
                              Registrable Shares expressly for use therein, or
