  5.  Representations and Warranties of the Investor.  Each of the Investors
      ----------------------------------------------

     5.6  Restricted Securities.  The Investor understands that the Securities
          ---------------------

such securities may be resold without registration under the 1933 Act only in
certain limited circumstances.

     5.7  Legends.  It is understood that, until registration for resale

Securities Act of 1933, as amended (the "Act"), and may not be offered, sold,
pledged, hypothecated, assigned or transferred except (i) pursuant to a

  7.  Covenants and Agreements of the Company.
      ---------------------------------------

      7.1  Subsequent Sale at Lower Price.
           ------------------------------

           (a)  Required Adjustments.  Subject to the exclusions contained in
                --------------------
Section 7.1(e) below, if during the period ending on the later of (i) twenty-
four (24) months following the Closing Date or (ii) twenty-one (21) months
following the date the registration statement contemplated by the Registration
Rights Agreement for the Registrable Securities (as defined in the Registration
Rights Agreement) is first declared effective (the "MFN Period"), the Company
sells any shares of its Common Stock in a capital raising transaction at a per
share selling price ("Per Share Selling Price") lower than the Purchase Price
per share set forth in Section 2 hereof, the Purchase Price per share of the
Shares

                                       10
<PAGE>

originally sold to the Investors hereunder shall be adjusted downward to equal
such lower Per Share Selling Price and Investors shall be entitled to receive
the additional shares as provided by Section 7.1(b); provided, however, that in
the event an Investor then owns less than 60% of the Shares originally acquired
by it hereunder, such Investor shall be entitled to additional shares only with
respect to the number of Shares originally acquired and then owned by such
Investor as provided in Section 7.1(b). The Company shall give to the Investors
written notice of any such sale within 24 hours of the closing of any such sale.
For so long as an Investor owns 60% or more of the Shares originally acquired by
such Investor hereunder, such Investor shall be entitled to the full benefit of
the Purchase Price adjustment required by this Section 7.1. The parties agree
that for purposes of this Section 7 (including determination of the number of
originally acquired shares held by an Investor) shares of Common Stock sold or
otherwise disposed of by an Investor shall be deemed to be those originally
acquired hereunder until that number is reduced to zero.

           (b)  Definitions.
                -----------

                (i)  For the purposes of this Section 7.1, the term "Per Share
Selling Price" as used in this Section 7.1 shall include the amount actually
paid by third parties for each share of Common Stock plus, in the event a fee in
excess of 7% is paid by the Company in connection with the transaction, any such
excess amount shall be deducted from the selling price pro rata to all shares
sold in the transaction to arrive at the Per Share Selling Price. A sale in a
capital raising transaction of shares of Common Stock shall include the sale or
issuance of rights, options, warrants or convertible securities under which the
Company is or may become obligated to issue shares of Common Stock, and in such
circumstances the Per Share Selling Price of the Common Stock covered thereby
shall also include the exercise or conversion price thereof (in addition to the
consideration received by the Company upon such sale or issuance less the excess
fee amount as provided above). In case of any such security issued within the
MFN Period in a "Variable Rate Transaction" or an "MFN Transaction" (each as
defined below), the Per Share Selling Price shall be deemed to be the lowest
conversion or exercise price at which such securities are converted or exercised
or might have been converted or exercised in the case of a Variable Rate
Transaction, or the lowest adjustment price in the case of an MFN Transaction.
If shares are issued for a consideration other than cash, the per share selling
price shall be the fair value of such consideration as determined in good faith
by the Board of Directors of the Company.

                (ii) The term "Variable Rate Transaction" shall mean a
transaction in which the company issues or sells (a) any debt or equity
securities that are convertible into, exchangeable or exercisable for, or
include the right to receive additional shares of Common Stock either (x) at a
conversion, exercise or exchange rate or other price that is based upon and/or
varies with the trading prices of or quotations for the Common Stock at any time
after the initial issuance of such debt or equity securities, or (y) with a
fixed conversion, exercise or exchange price that is subject to being reset at
some future date after the initial issuance of such debt or equity security or
upon the occurrence of specified or contingent events directly or indirectly
related to the business of the Company or the market for the Common Stock (but
excluding standard stock split anti-dilution provisions), or (b) any securities
of the Company pursuant to an "equity line" structure which provides for the
sale, from time to time, of securities of the Company which are registered for
resale pursuant to the 1933 Act.

                                       11
<PAGE>

                (iii)  The term "MFN Transaction" shall mean a transaction in
which the Company issues or sells any equity securities in a capital raising
transaction or series of related transactions involving more than $500,000 in
the aggregate (the "New Offering") which grants to an investor (the "New
Investor") the right to receive additional shares based upon future equity
raising transactions of the Company on terms more favorable than those granted
to the New Investor in the New Offering.

                (iv)   The term "MFN Period" shall have the meaning set forth
in Section 7.1(a), above.

           (c)  Adjustment Mechanism.  If an adjustment of the Purchase Price
                --------------------
is required pursuant to Section 7.1(a), the Company shall deliver to the
Investors within eight calendar days of the closing of the transaction giving
rise to the adjustment or by such other date as may be required by Section
7.1(d) ("Delivery Date") each Investor's pro-rata share of such number of
additional shares of Common Stock equal to (i) the aggregate Purchase Price paid
by such Investor divided by the adjusted Per Share Purchase Price as required
under Section 7.1(a), minus (ii) the total number of shares of Common Stock
previously delivered to that Investor hereunder; provided however, that the
                                                 ----------------
Company shall delay effecting such adjustment, in whole or in part, to the
extent required by Section 7.1(d). In the event the Company fails to deliver the
additional shares by the applicable Delivery Date, the Company shall be liable
to the Investors for a penalty equal to 2% of the aggregate Purchase Price
adjustment per month (in each instance to such Investor pro rata in accordance
with its participation in this offering), payable in Common Stock or cash, at
each Investor's election.

           (d)  Limitation on Number of Shares.
                ------------------------------

                (i)   If by way of any adjustment required by this Section 7.1,
an Investor would receive a number of shares of Common Stock such that the total
number of such shares held by the Investor as of the date of such adjustment
would be greater than 9.90% but less than 13.0% of the total outstanding Common
Stock of the Company, then the Company shall not effect the adjustment required
by this Section to the extent necessary to avoid causing the aforesaid
limitation to be exceeded until 120 days following the date such adjustment
would have otherwise been made.

                (ii)  If by way of any adjustment required by this Section 7.1,
an Investor would receive a number of shares of Common Stock such that the total
number of such shares held by the Investor as of the date of such adjustment
would equal or exceed 13.0% of the total outstanding Common Stock of the
Company, then the Company shall not effect the adjustment required by this
Section to the extent necessary to avoid causing the aforesaid limitation to be
exceeded until 180 days following the date such adjustment would have otherwise
been made.

                                       12
<PAGE>

                (iii)  In no event shall the Company issue to the Investors
additional shares pursuant to an adjustment required by this Section 7.1 such
that the total number of shares issued to the Investors (when added to the
Warrant Shares) would exceed 19.9% of the Company's issued and outstanding
shares of Common Stock on the date hereof. Instead, the Company shall redeem
such excess shares at 110% of the Per Share Purchase Price, as adjusted. Only
shares acquired pursuant to this Agreement will be included in determining
whether the limitations would be exceeded for purposes of this
Section 7.1(d)(iii).

           (e) Capital Adjustments.  In case of any stock split or reverse
               -------------------
stock split, stock dividend, reclassification of the common stock,
recapitalization, merger or consolidation, or like capital adjustment affecting
the Common Stock of the Company, the provisions of Section 7.1 shall be applied
in a fair, equitable and reasonable manner so as to give effect, as nearly as
may be, to the purposes hereof.

           (f) Exclusions.  Section 7.1(a) shall not apply to (i) sales of
               ----------
shares of Common Stock by the Company upon conversion or exercise of any
convertible securities, options or warrants outstanding prior to the date
hereof; or (ii) sales of shares of Common Stock by the Company pursuant to the
provisions of any shareholder-approved option or similar plan heretofore or
hereafter adopted by the Company.

           (g) Extension of MFN Period.  If, prior to the date of effectiveness
               -----------------------
of the registration statement contemplated by the Registration Rights Agreement,
the Company issues or sells for cash in a non-public offering any equity
securities in a capital raising transaction not prohibited by Section 7.2 below,
the MFN Period shall be extended by two months for each $1,000,000 of gross
proceeds received by the Company in such a transaction or series of such
transactions.

           (h) Extension of MFN Period.  If, prior to the date of effectiveness
               -----------------------
of the registration statement contemplated by the Registration Rights Agreement,
the Company issues securities in a MFN Transaction permitted under
Section 7.2(a) below to a corporate partner (for gross proceeds of up to
$4 million), the MFN Period shall be extended by two months for each $800,000 of
gross proceeds received by the Company in such a transaction or series of
transactions.

      7.2  Limitation on Transactions.
           --------------------------

           (a) Until the date of effectiveness of the registration statement
contemplated by the Registration Rights Agreement, without the prior written
consent of the Investors (which consent may be withheld in the Investors'
discretion), the Company shall not (i) issue or sell or agree to issue or sell
any securities for cash in a non-public MFN Transaction provided, however, that
the Company may issue such securities to a corporate partner of the Company for
gross proceeds of up to $4 million; or (ii) issue or sell, or agree to issue or
sell, any securities for cash in a non-public Variable Rate Transaction.

                                       13
<PAGE>

           (b) During the period after effectiveness of the registration
statement contemplated by the Registration Rights Agreement and until the
expiration of the MFN Period, without the prior written consent of the Investors
(which consent may be withheld in the Investors' discretion), the Company shall
not (i) issue or sell or agree to issue or sell any securities for cash in a
non-public MFN Transaction; provided, however, that the Company may issue such
securities in a single transaction to a corporate partner of the Company for
gross proceeds of up to $4 million and, in the same transaction, to another
(non-corporate partner) third party for gross proceeds of up to $1 million,
(ii) issue or sell, or agree to issue or sell, any securities for cash in a non-

percent (8%) of the Company's outstanding shares of Common Stock.


      7.3  Right of Investors to Participate in Future Transactions. The Company
           --------------------------------------------------------
agrees that during the MFN Period the Investors will have a right to participate
in future non-public capital raising transactions as set forth in this
Section 7.3. The Company shall give advance written notice to the Investors
prior to any offer or sale of any of its equity securities or any securities
convertible into or exchangeable or exercisable for such securities in a non-
public capital raising transaction. Such notice shall be given upon the
Company's receipt of a written commitment from a third party to engage in such a
transaction with the Company and when the Company reasonably believes that such
transaction will be consummated and publicly announced within two weeks. Prior
to the closing of any such transaction, each Investor shall have the right to
participate in up to 15% of such new offering (or in the case of a Variable Rate
Transaction, up to 50% of such new offering) and purchase such equity securities
for the same consideration and on the same terms and conditions as contemplated
for such third-party sale. An Investor's right to participate in the new
offering shall initially be limited to pro rata participation in accordance with
such Investor's participation in this offering. If an Investor chooses not to
participate in the new offering to some extent or at all, the other Investors
shall have the right, on a pro rata basis to such participation in the new
offering. In order to exercise this right, an Investor must give written notice
to the Company of the Investor's election to participate and such notice must be
given within one week following receipt of the notice from the Company. In the
event the Company gives notice to the Investors of an expected transaction
pursuant to this Section 7.3 but cannot consummate such transaction, the Company
will give the Investors prompt written notice of the cancellation of such
transaction. After written notice of a possible transaction has been given by
the Company pursuant to this Section 7.3, the Investors shall refrain from
trading in the Company's securities until such transaction has been publicly
announced or cancelled. If, subsequent to the Company giving notice to the
Investors hereunder, the terms and conditions of the proposed third-party sale
are changed in any way, the Company shall be required to provide a new notice to
the Investors hereunder and the Investors shall have the right to participate in
the offering on such changed terms and conditions as provided hereunder.

legal matters set forth in Schedule 7.4 hereto.

of Common Stock as shall be necessary to permit the exercise of the Warrants in
accordance with the terms of the Warrants.

      7.6  Reports.  Within one week of filing the following reports with the
           -------

the Company shall send a copy of the following reports to each Investor by

           --------------

its subsidiaries to, take any action, enter into any agreement or make any

      7.9  Insurance.  For so long as any Investor beneficially owns any of the
           ---------
Securities, the Company shall, and shall cause each subsidiary to, have in full
force and effect (a) insurance reasonably believed to be adequate on all assets
and activities of a type customarily insured, covering property damage and loss

authorities, except to the extent non-compliance (in one instance or in the
aggregate) would not have a Material Adverse Effect.

      7.11 Listing of Underlying Shares and Related Matters.  The Company hereby
           ------------------------------------------------
agrees, promptly following the Closing of the transactions contemplated by this
Agreement, to take such action to cause the Shares and the Warrant Shares to be
listed on the Nasdaq National Market as promptly as possible but no later than

Agreement. The Company further agrees that if the Company applies to have its
Common Stock or other securities traded on any other principal stock exchange or
market, it will include in such application the Common Stock underlying the
Warrants, and will take such other action as is necessary to cause such Common
Stock to be so listed. The Company will take all action necessary to continue
the listing and trading of its Common Stock on the Nasdaq National Market and
will comply in all respects with the Company's reporting, filing and other
obligations under the bylaws or rules of such exchange, as applicable, to ensure
the continued eligibility for trading of the Shares and the Warrant Shares

<PAGE>

surviving or successor entity in such transaction (a) assumes the Company's
obligations hereunder and under the agreements and instruments entered into in

sufficient number of shares of Common Stock authorized and available for
issuance in order to fulfill its obligations hereunder and effect the exercise
in full of all Warrants outstanding as of the date of such transaction; (b) has
no legal, contractual or other restrictions on its ability to perform the
obligations of the Company hereunder and under the agreements and instruments
entered into in connection herewith; and (c) (i) is a publicly traded
corporation whose common stock and the shares of capital stock issuable upon
exercise of the Warrants are (or would be upon issuance thereof) listed for
trading on the Nasdaq National Market, New York Stock Exchange or American Stock
Exchange, or (ii) if not such a publicly traded corporation, then the buyer
agrees that it will, at the election of an Investor, purchase such Investor's
Shares (and Warrant Shares) at a price equal to 120% of the Per Share Purchase
Price of such Shares unless the Common Stock of the Company, for ten consecutive
trading days after public announcement of the transaction closes at or above
such price in which case the Investor will have no such election right. The
rights of Investors provided in clause (c)(ii) shall expire thirty (30) months
after the date hereof.

      --------
contained in this Agreement shall be deemed to be representations, warranties,
covenants and agreements as of the date hereof and shall survive the execution

Section 7 hereof shall survive in accordance therewith.

  9.  Arbitration.
      -----------

      9.1  Scope.  Resolution of any and all disputes arising from or in

connection with the Agreements, whether based on contract, tort, common law,
equity, statute, regulation, order or otherwise ("Disputes"), shall be
exclusively governed by and settled in accordance with the provisions of this
Section 9; provided, that the foregoing shall not preclude equitable or other
judicial relief to enforce the provisions hereof or to preserve the status quo
pending resolution of Disputes hereunder.

      9.2. Binding Arbitration.  The parties hereby agree to submit all Disputes
           -------------------
to arbitration for final and binding resolution. Either party may initiate such
arbitration by delivery of a demand therefor (the "Arbitration Demand") to the
other party. The arbitration shall be conducted in New York, New York by a sole
arbitrator selected by agreement of the parties not later than 10 days after
delivery of the Arbitration Demand, or, failing such agreement, appointed
pursuant to the Commercial Arbitration Rules of the America Arbitration
Association, as amended from time to time (the "AAA Rules"). If the arbitrator
becomes unable to serve, his successor(s) shall be similarly selected or
appointed.

      9.3. Procedure.  The arbitration shall be conducted pursuant to the
           ---------
Federal Arbitration Act and such procedures as the parties may agree or, in the
absence of or failing such agreement, pursuant to the AAA Rules. Notwithstanding
the foregoing, (a) each party shall have the right to conduct limited discovery
of information relevant to the Dispute; (b) each party shall

                                       17
<PAGE>

provide to the other, reasonably in advance of any hearing, copies of all

record thereof.

      9.4. Timing.  The arbitrator shall use best efforts to complete all
           ------
hearings not later than 90 days after his or her selection or appointment, and
shall use best efforts to make a final award not later than 30 days thereafter.
The arbitrator shall apportion all costs and expenses of the arbitration,
including the arbitrator's fees and expenses, and fees and expenses of experts
("Arbitration Costs") between the prevailing and non-prevailing party as the
arbitrator shall deem fair and reasonable. In circumstances where a Dispute has
been asserted or defended against on grounds that the arbitrator deems
manifestly unreasonable, the arbitrator may assess all Arbitration Costs against
the non-prevailing party and may include in the award the prevailing party's
attorney's fees and expenses in connection with any and all proceedings under
this Section 9. Notwithstanding the foregoing, in no event may the arbitrator
award multiple or punitive damages.

counsel prior to its filing or other submission.

        (ii) Additional Registrable Securities. Upon the written demand of any

the

                                       2
<PAGE>

resale of the Additional Registrable Securities in an amount equal to the
number of shares of Common Stock issued to and designated in the demand by such
Investor. Such Registration Statement also shall cover, to the extent allowable
under the 1933 Act and the Rules promulgated thereunder (including Rule 416),
such indeterminate number of additional shares of Common Stock resulting from
stock splits, stock dividends or similar transactions with respect to the
Additional Registrable Securities. No securities shall be included in the
Registration Statement without the consent of the Investor other than the
Registrable Securities and the Additional Registrable Securities. The
Registration Statement (and each amendment or supplement thereto, and each
request for acceleration of effectiveness thereof) shall be provided in
accordance with Section 3(c) to the Investor and its counsel prior to its filing
or other submission.

        (b) Expenses. The Company will pay all expenses associated with each
            --------
registration, including the Investors' reasonable expenses in connection with
the registration (including the reasonable expenses of one counsel designated by
the Investors) but excluding discounts, commissions, fees of underwriters,
selling brokers, dealer managers or similar securities industry professionals.

        (c) Effectiveness.
            -------------

        (i)  The Company shall use its best efforts to have each Registration
Statement declared effective as soon as practicable.  If (A) the Registration
Statement covering Registrable Securities is not declared effective by the SEC
within three (3) months following the Closing Date, or the Registration
Statement covering Additional Registrable Securities is not declared effective
by the SEC within three (3) months following the demand of an Investor relating
to the Additional Registrable Securities covered thereby, (each, a "Registration
Date"), (B) after a Registration Statement has been declared effective by the
SEC, sales cannot be made pursuant to such Registration Statement (by reason of
a stop order, or the Company's failure to update the Registration Statement) but
except as excused pursuant to subparagraph (ii) below, or (C) the Common Stock
generally or the Registrable Securities specifically is not listed or included
for quotation on the Nasdaq National Market System, the Nasdaq Small Cap Market,
the New York Stock Exchange or the American Stock Exchange, then the Company
will make pro-rata payments to each Investor, as liquidated damages and not as a
penalty, in an amount equal to 2% of the aggregate amount paid by such Investor
on the Closing Date to the Company for any month or pro rata for any portion
thereof following the Registration Date during which any of the events described
in (A) or (B) or (C) above occurs and is continuing (the "Blackout Period").
The Blackout Period shall terminate upon (x) the effectiveness of the applicable
Registration Statement in the case of (A) and (B) above; (y) listing or
inclusion of the Common Stock on the Nasdaq National Market System, the Nasdaq
Small Cap Market, the New York Stock Exchange or the American Stock Exchange in
the case of (C) above; and (z) in the case of the events described in (A) or (B)
above, the earlier termination of the Registration Period (as defined in Section
3(a) below).  The amounts payable as liquidated damages pursuant to this
paragraph shall be payable, at the option of the Company, in lawful money of the
United States or in shares of Common Stock at the Market Price (as that term is
defined in the Purchase Agreement), and amounts payable as liquidated damages
shall be paid monthly on the last day of each month following the commencement
of the Blackout Period until the termination of the Blackout Period.

                                       3
<PAGE>

Amounts payable as liquidated damages hereunder shall cease when an Investor no
longer holds Warrants or Registrable Securities, or Additional Registrable
Securities, as applicable.

        (ii) For not more than ten (10) consecutive trading days or for a
total of not more than twenty (20) trading days in any twelve (12) month period,
the Company may delay the disclosure of material non-public information
concerning the Company, by terminating or suspending effectiveness of any
registration contemplated by this Section containing such information, the
disclosure of which at the time is not, in the good faith opinion of the
Company, in the best interests of the Company (an "Allowed Delay"); provided,
that the Company shall promptly (a) notify the Investors in writing of the
existence of (but in no event, without the prior written consent of an Investor,
shall the Company disclose to such Investor any of the facts or circumstances
regarding) material non-public information giving rise to an Allowed Delay, and
(b) advise the Investors in writing to cease all sales under the Registration
Statement until the end of the Allowed Delay. The duration of the MFN Period
provided for in the Purchase Agreement will be extended by the number of days of
any and all Allowed Delays.

        (d) Underwritten Offering. If any offering pursuant to a Registration
            ---------------------
Statement pursuant to Section 2(a) hereof involves an underwritten offering, the
Company shall have the right to select an investment banker and manager to
administer the offering, which investment banker or manager shall be reasonably
satisfactory to the Investors.

        3. Company Obligations. The Company will use its best efforts to effect
           -------------------
the registration of the Registrable Securities and Additional Registrable
Securities in accordance with the terms hereof, and pursuant thereto the Company
will, as expeditiously as possible:

        (a) use its best efforts to cause such Registration Statement to become
effective and to remain continuously effective for a period that will terminate
upon the earlier of the date on which all Registrable Securities or Additional
Registrable Securities, as the case may be, covered by such Registration
Statement, as amended from time to time, have been sold (the "Registration
Period");

        (b) prepare and file with the SEC such amendments and post-effective
amendments to the Registration Statement and the Prospectus as may be necessary
to keep the Registration Statement effective for the period specified in Section
3(a) and to comply with the provisions of the 1933 Act and the 1934 Act with
respect to the distribution of all Registrable Securities and Additional
Registrable Securities; provided that, at least three (3) days prior to the
filing of a Registration Statement or Prospectus, or any amendments or
supplements thereto, the Company will furnish to the Investors copies of all
documents proposed to be filed, which documents will be subject to the comments
of the Investors;

        (c) permit one counsel designated by the Investors to review each
Registration Statement and all amendments and supplements thereto no fewer than
seven (7) days prior to their filing with the SEC and not file any document to
which such counsel reasonably objects;

                                       4

        (d) furnish to the Investors and their legal counsel (i) promptly after
the same is prepared and publicly distributed, filed with the SEC, or received
by the Company, one copy of any Registration Statement and any amendment
thereto, each preliminary prospectus and Prospectus and each amendment or
supplement thereto, and each letter written by or on behalf of the Company to
the SEC or the staff of the SEC, and each item of correspondence from the SEC or
the staff of the SEC, in each case relating to such Registration Statement
(other than any portion of any thereof which contains information for which the
Company has sought confidential treatment), and (ii) such number of copies of a
Prospectus, including a preliminary prospectus, and all amendments and
supplements thereto and such other documents as each Investor may reasonably
request in order to facilitate the disposition of the Registrable Securities and
Additional Registrable Securities owned by such Investor;

        (e) in the event the Company selects an underwriter for the offering,
the Company shall enter into and perform its reasonable obligations under an
underwriting agreement, in usual and customary form, including, without
limitation, customary indemnification and contribution obligations, with the
underwriter of such offering;

        (f) if required by the underwriter, at the request of the Investors, the
Company shall furnish, on the date that Registrable Securities or Additional
Registrable Securities, as applicable, are delivered to an underwriter, if any,

of such date, from counsel representing the Company for purposes of such
Registration Statement, in form, scope and substance as is customarily given in
an underwritten public offering, addressed to the underwriter and the Investors
and (ii) a letter, dated such date, from the Company's independent certified
public accountants in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering,
addressed to the underwriter and the Investors;

        (g) make effort to prevent the issuance of any stop order or other
suspension of effectiveness and, if such order is issued, obtain the withdrawal
of any such order at the earliest possible moment;

        (h) furnish to each Investor at least five copies of the Registration
Statement and any post-effective amendment thereto, including financial
statements and schedules by courier pursuant to the notice requirements of
Section 10.4 of the Purchase Agreement;

        (i) prior to any public offering of Registrable Securities or Additional
Registrable Securities, use its reasonable best efforts to register or qualify
or cooperate with the Investors and their counsel in connection with the
registration or qualification of such Registrable Securities or Additional
Registrable Securities, as applicable, for offer and sale under the securities

writing and do any and all other reasonable acts or things necessary or
advisable to enable the distribution in such jurisdictions of the Registrable
Securities or Additional Registrable Securities covered by the Registration
Statement;

                                       5
<PAGE>

        (j) cause all Registrable Securities or Additional Registrable
Securities covered by a Registration Statement to be listed on each securities
exchange, interdealer quotation system or other market on which similar
securities issued by the Company are then listed;

        (k) immediately notify the Investors, at any time when a Prospectus
relating to the Registrable Securities or Additional Registrable Securities is
required to be delivered under the Securities Act, upon discovery that, or upon
the happening of any event as a result of which, the Prospectus included in such
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state any 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 at the request of any such holder, promptly
prepare and furnish to such holder 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 Registrable Securities or Additional
Registrable Securities, as applicable, 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

        (l) otherwise use its best efforts to comply with all applicable rules

actions as may be reasonably necessary to facilitate the registration of the
Registrable Securities and Additional Registrable Securities, if applicable,
hereunder; and make available to its security holders, as soon as reasonably
practicable, but not later than the Availability Date (as defined below), an
earnings statement covering a period of at least twelve months, beginning after

shall satisfy the provisions of Section 11(a) of the 1933 Act (for the purpose
of this subsection 3(m), "Availability Date" means the 45th day following the
end of the fourth fiscal quarter that includes the effective date of such
Registration Statement, except that, if such fourth fiscal quarter is the last
quarter of the Company's fiscal year, "Availability Date" means the 90th day
after the end of such fourth fiscal quarter).

        4.  Obligations of the Investors.
            ----------------------------

        (a) It shall be a condition precedent to the obligations of the Company
to complete the registration pursuant to this Agreement with respect to the
Registrable Securities or Additional Registrable Securities, as applicable, that
each Investor shall furnish in writing to the Company such information regarding
itself, the Registrable Securities or Additional Registrable Securities, as
applicable, held by it and the intended method of disposition of the Registrable
Securities or Additional Registrable Securities, as applicable, held by it, as
shall be reasonably required to effect the registration of such Registrable
Securities or Additional Registrable Securities, as applicable, and shall
execute such documents in connection with such registration as the Company may
reasonably request. At least fifteen (15) business days prior to the first
anticipated filing date of any Registration Statement, the Company shall notify
each Investor of the information the Company requires from such Investor if such
Investor elects to have any of the Registrable Securities or Additional
Registrable Securities included in the Registration

                                       6
<PAGE>

Statement. An Investor shall provide such information to the Company at least
five (5) business days prior to the first anticipated filing date of such
Registration Statement if such Investor elects to have any of the Registrable
Securities or Additional Registrable Securities included in the Registration
Statement.

        (b) Each Investor, by its acceptance of the Registrable Securities and
Additional Registrable Securities, if any, agrees to cooperate with the Company
as reasonably requested by the Company in connection with the preparation and
filing of a Registration Statement hereunder, unless such Investor has notified
the Company in writing of its election to exclude all of its Registrable
Securities or Additional Registrable Securities, as applicable, from the
Registration Statement, in which case the Investor shall be deemed to have
waived its rights to have Registrable Securities or Additional Registrable
Securities, as the case may be, registered under this Agreement, unless the
Investor has good cause for such an election.

        (c) In the event the Company determines to engage the services of an
underwriter, each Investor agrees to enter into and perform its obligations
under an underwriting agreement, in usual and customary form, including, without
limitation, customary indemnification and contribution obligations, with the
managing underwriter of such offering and take such other actions as are
reasonably required in order to expedite or facilitate the dispositions of the
Registrable Securities or Additional Registrable Securities, as applicable.

        (d) Each Investor agrees that, upon receipt of any notice from the
Company of the happening of any event rendering a Registration Statement no
longer effective, such Investor will immediately discontinue disposition of
Registrable Securities or Additional Registrable Securities pursuant to the
Registration Statement covering such Registrable Securities or Additional
Registrable Securities, until the Investor's receipt of the copies of the
supplemented or amended prospectus filed with the SEC and declared effective
and, if so directed by the Company, the Investor shall deliver to the Company
(at the expense of the Company) or destroy (and deliver to the Company a
certificate of destruction) all copies in the Investor's possession of the
prospectus covering the Registrable Securities or Additional Registrable
Securities, as applicable, current at the time of receipt of such notice.

        (e) No Investor may participate in any underwritten registration
hereunder unless it (i) agrees to sell the Registrable Securities or Additional
Registrable Securities, as applicable, on the basis provided in any underwriting
arrangements in usual and customary form entered into by the Company, (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements, and (iii) agrees to pay its pro rata share of
all underwriting discounts and commissions and any expenses in excess of those
payable by the Company pursuant to the terms of this Agreement.

        5.  Indemnification.
            ---------------

        (a) Indemnification by Company. The Company agrees to indemnify and hold
            --------------------------
harmless, to the fullest extent permitted by law the Investors, each of their
officers, directors, partners and employees and each person who controls the
Investors (within the meaning of the 1933 Act) and each underwriter of
Registrable Securities and Additional Registrable Securities against all losses,
claims, damages, liabilities, costs (including, without limitation, reasonable
attorney's fees) and expenses imposed on such person caused by (i) any untrue or
alleged untrue statement of a material fact contained in any Registration
Statement, Prospectus or any preliminary prospectus or any amendment or
supplement thereto or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as the same are based upon any
information furnished in writing to the Company by such Investors, expressly for
use therein, or (ii) any violation by the Company of any federal, state or
common law, rule or regulation applicable to the Company in connection with any
Registration Statement, Prospectus or any preliminary prospectus, or any
amendment or supplement thereto, and shall reimburse in accordance with
subparagraph (c) below, each of the foregoing persons for any legal and any
other expenses reasonably incurred in connection with investigating or defending
any such claims. The foregoing is subject to the condition that, insofar as the
foregoing indemnities relate to any untrue statement, alleged untrue statement,
omission or alleged omission made in any preliminary prospectus or Prospectus
that is eliminated or remedied in any Prospectus or amendment or supplement
thereto, the above indemnity obligations of the Company shall not inure to the
benefit of any indemnified party if a copy of such corrected Prospectus or
amendment or supplement thereto had been made available to such indemnified
party and was not sent or given by such indemnified party at or prior to the
time such action was required of such indemnified party by the 1933 Act and if
delivery of such Prospectus or amendment or supplement thereto would have
eliminated (or been a sufficient defense to) any liability of such indemnified
party with respect to such statement or omission. Indemnity under this Section
5(a) shall remain in full force and effect regardless of any investigation made
by or on behalf of any indemnified party and shall survive the permitted
transfer of the Registrable Securities and Additional Registrable Securities.

        (b) Indemnification by Investor. In connection with any registration
            ---------------------------
pursuant to the terms of this Agreement, each Investor will furnish to the
Company in writing such information as the Company reasonably requests
concerning the holders of Registrable Securities and Additional Registrable
Securities or the proposed manner of distribution for use in connection with any
Registration Statement or Prospectus and agrees, severally but not jointly, to
indemnify and hold harmless, to the fullest extent permitted by law, the
Company, its directors, officers, employees, stockholders and each person who
controls the Company (within the meaning of the 1933 Act) and each underwriter
of Registrable Securities and Additional Registrable Securities against any
losses, claims, damages, liabilities and expense (including reasonable
attorney's fees) resulting from any untrue statement of a material fact or any
omission of a material fact required to be stated in the Registration Statement
or Prospectus or preliminary prospectus or amendment or supplement thereto or
necessary to make the statements therein not misleading, to the extent, but only
to the extent that such untrue statement or omission is contained in any
information furnished in writing by such Investor to the Company specifically
for

                                       8
<PAGE>

inclusion in such Registration Statement or Prospectus or amendment or
supplement thereto and that such information was substantially relied upon by
the Company in preparation of the Registration Statement or Prospectus or any
amendment or supplement thereto. In no event shall the liability of an Investor
be greater in amount than the dollar amount of the proceeds (net of all expense
paid by such Investor and the amount of any damages such holder has otherwise
been required to pay by reason of such untrue statement or omission) received by
such Investor upon the sale of the Registrable Securities or Additional
Registrable Securities included in the Registration Statement giving rise to
such indemnification obligation.

        (c) Conduct of Indemnification Proceedings. Any person entitled to
            --------------------------------------
indemnification hereunder shall (i) give prompt notice to the indemnifying party
of any claim with respect to which it seeks indemnification and (ii) permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party; provided that any person entitled to
indemnification hereunder shall have the right to employ separate counsel and to
participate in the defense of such claim, but the fees and expenses of such
counsel shall be at the expense of such person unless (a) the indemnifying party
has agreed to pay such fees or expenses, or (b) the indemnifying party shall
have failed to assume the defense of such claim and employ counsel reasonably
satisfactory to such person or (c) in the reasonable judgment of any such
person, based upon written advice of its counsel, a conflict of interest exists
between such person and the indemnifying party with respect to such claims (in
which case, if the person notifies the indemnifying party in writing that such
person elects to employ separate counsel at the expense of the indemnifying
party, the indemnifying party shall not have the right to assume the defense of
such claim on behalf of such person); and provided, further, that the failure of
any indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations hereunder, except to the extent that such
failure to give notice shall materially adversely affect the indemnifying party
in the defense of any such claim or litigation. It is understood that the
indemnifying party shall not, in connection with any proceeding in the same
jurisdiction, be liable for fees or expenses of more than one separate firm of
attorneys at any time for all such indemnified parties. No indemnifying party
will, except with the consent of the indemnified party, consent to entry of any
judgment or enter into any settlement that does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect of such claim or litigation.

        (d) Contribution. If for any reason the indemnification provided for in
            ------------
the preceding paragraphs (a) and (b) is unavailable to an indemnified party or
insufficient to hold it harmless, other than as expressly specified therein,
then the indemnifying party shall contribute to the amount paid or payable by
the indemnified party as a result of such loss, claim, damage or liability in
such proportion as is appropriate to reflect the relative fault of the
indemnified party and the indemnifying party, as well as any other relevant
equitable considerations. No person guilty of fraudulent misrepresentation
within the meaning of Section 11(f) of the 1933 Act shall be entitled to
contribution from any person not guilty of such fraudulent misrepresentation. In
no event shall the contribution obligation of a holder of Registrable Securities
or Additional Registrable Securities be greater in amount than the dollar amount
of the proceeds (net of all expenses paid by such holder and the amount of any
damages such holder has otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged

                                       9
<PAGE>

omission) received by it upon the sale of the Registrable Securities or
Additional Registrable Securities giving rise to such contribution obligation.

hereunder to any successor-in-interest corporation, and such successor-in-
interest shall assume such rights and duties, in the event of a merger or
consolidation of the Company with or into another corporation or the sale of all
or substantially all of the Company's assets.

        (e) Benefits of the Agreement. The terms and conditions of this
            -------------------------

hereto or their respective successors and assigns any rights, remedies,
obligations, or liabilities under or by reason of this Agreement, except as

     THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE
ABSENCE OF A REGISTRATION STATEMENT COVERING THIS WARRANT UNDER SAID ACT OR AN
EXEMPTION FROM REGISTRATION UNDER SAID ACT.

     VOID AFTER 5:00 P.M. EASTERN TIME ON JUNE 9, 2003  ("EXPIRATION DATE").


                             CAMBRIDGE HEART, INC.

                     WARRANT TO PURCHASE 19,048 SHARES OF
           COMMON STOCK, PAR VALUE $0.001 PER SHARE ("Common Stock")

     For VALUE RECEIVED, Geoffrey H. Galley ("Warrantholder"), is entitled to
purchase, subject to the provisions of this Warrant, from Cambridge Heart, Inc.,
a Delaware corporation ("Company"), at any time not later than 5:00 P.M.,
Eastern time, on the Expiration Date, at an exercise price per share equal to
$7.22 (the exercise price in effect being herein called the "Warrant Price"),
19,048 shares ("Warrant Shares") of Common Stock. The number of Warrant Shares
purchasable upon exercise of this Warrant and the Warrant Price shall be subject
to adjustment from time to time as described herein.

     Section 1.  Registration.  The Company shall maintain books for the
                 ------------
transfer and registration of the Warrant. Upon the initial issuance of the
Warrant, the Company shall issue and register the Warrant in the name of the
Warrantholder.

     Section 2.  Transfers.  As provided herein, the Warrant may be transferred
                 ---------
only pursuant to a registration statement filed under the Securities Act of
1933, as amended ("Securities Act") or an exemption from registration
thereunder. Subject to such restrictions, the Company shall transfer the Warrant
from time to time upon the books to be maintained by the Company for that
purpose, upon surrender thereof for transfer properly endorsed or accompanied by
appropriate instructions for transfer upon any such transfer, and a new Warrant
shall be issued to the transferee and the surrendered Warrant shall be canceled
by the Company.

     Section 3.  Exercise of Warrant.  Subject to the provisions hereof, the
                 -------------------
Warrantholder may exercise the Warrant in whole or in part at any time upon
surrender of the Warrant, together with delivery of the duly executed Warrant
exercise form attached hereto (the "Exercise Agreement"), to the Company during
normal business hours on any business day at the Company's principal executive
offices (or such other office or agency of the Company as it may designate by
notice to the holder hereof). The Warrantholder will not be required to make any
cash payment upon exercise hereunder, but shall only be entitled to effect a
cashless exercise of this Warrant for that number of Warrant Shares indicated in
the Exercise Agreement.
<PAGE>

The Warrant Shares so purchased shall be deemed to be issued to the holder
hereof or such holder's designee, as the record owner of such shares, as of the
close of business on the date on which this Warrant shall have been surrendered
(or evidence of loss, theft or destruction thereof and security or indemnity
satisfactory to the Company) and the completed Exercise Agreement shall have
been delivered. Certificates for the Warrant Shares so purchased, representing
the aggregate number of shares specified in the Exercise Agreement, shall be
delivered to the holder hereof within a reasonable time, not exceeding ten (10)
business days, after this Warrant shall have been so exercised. The certificates
so delivered shall be in such denominations as may be requested by the holder
hereof and shall be registered in the name of such holder or such other name as
shall be designated by such holder. If this Warrant shall have been exercised
only in part, then, unless this Warrant has expired, the Company shall, at its
expense, at the time of delivery of such certificates, deliver to the holder a
new Warrant representing the number of shares with respect to which this Warrant
shall not then have been exercised.

     To effect the cashless exercise, the Warrantholder shall include in the
Exercise Agreement a calculation of the number of shares of Common Stock to be
issued determined by multiplying the number of Warrant Shares to which it would
otherwise be entitled by a fraction, the numerator of which shall be the
difference between the Market Price per share of the Common Stock on the date of
exercise and the Warrant Price, and the denominator of which shall be such
Market Price per share of the Common Stock. For this purpose, the "Market Price"
of the Common Stock shall be the closing price of the Common Stock as reported
by the Nasdaq National Market on the trading day first preceding the date in
question.

     Each exercise hereof shall constitute the representation and warranty of
the Warrantholder to the Company that the representations and warranties
contained in Article 5 of the Purchase Agreement (as defined below) are true and
correct in all material respects as of the time of such exercise.

     Section 4.  Compliance with the Securities Act of 1933.  Neither this
                 ------------------------------------------
Warrant nor the Common Stock issued upon exercise hereof nor any other security
issued or issuable upon exercise of this Warrant may be offered or sold except
as provided in this agreement and in conformity with the Securities Act, and
then only against receipt of an agreement of such person to whom such offer of
sale is made to comply with the provisions of this Section 4 with respect to any
resale or other disposition of such security. The Company may cause the legend
set forth on the first page of this Warrant to be set forth on each Warrant or
similar legend on any security issued or issuable upon exercise of this Warrant,
unless counsel for the Company is of the opinion as to any such security that
such legend is unnecessary.

     Section 5.  Payment of Taxes.  The Company will pay any documentary stamp
                 ----------------
taxes attributable to the initial issuance of Warrant Shares issuable upon the
exercise of the Warrant; provided, however, that the Company shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issue or delivery of any

                                       2
<PAGE>

certificates for Warrant Shares in a name other than that of the registered
holder of the Warrant in respect of which such shares are issued, and in such
case, the Company shall not be required to issue or deliver any certificate for
Warrant Shares or any Warrant until the person requesting the same has paid to
the Company the amount of such tax or has established to the Company's
satisfaction that such tax has been paid. The holder shall be responsible for
income taxes due under federal or state law, if any such tax is due.

     Section 6.  Mutilated or Missing Warrants.  In case the Warrant shall be
                 -----------------------------
mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and
substitution of and upon cancellation of the mutilated Warrant, or in lieu of
and substitution for the Warrant lost, stolen or destroyed, a new Warrant of
like tenor and for the purchase of a like number of Warrant Shares, but only
upon receipt of evidence reasonably satisfactory to the Company of such loss,
theft or destruction of the Warrant, and with respect to a lost, stolen or
destroyed Warrant, reasonable indemnity or bond, if requested by the Company.

     Section 7.  Reservation of Common Stock.  The Company hereby represents and
                 ---------------------------
warrants that there have been reserved, and the Company shall at all applicable
times keep reserved until issued (if necessary) as contemplated by this Section
7, out of the authorized and unissued Common Stock, sufficient shares to provide
for the exercise of the rights of purchase represented by the Warrant. The
Company further represents and warrants that the transfer agent for the Common
Stock ("Transfer Agent"), and every subsequent transfer agent for the Common
Stock or other shares of the Company's capital stock issuable upon the exercise
of any of the right of purchase or conversion aforesaid, shall be irrevocably
authorized and directed at all times to issue such number of authorized and
unissued shares of Common Stock as shall be issuable upon the proper exercise
hereof. The Company agrees that all Warrant Shares issued upon exercise of the
Warrant shall be, at the time of delivery of the certificates for such Warrant
Shares, duly authorized, validly issued, fully paid and non-assessable shares of
Common Stock of the Company. The Company will keep a conformed copy of this
Warrant on file with the Transfer Agent and with every subsequent transfer agent
for the Common Stock or other shares of the Company's capital stock issuable
upon the exercise of the rights of purchase represented by the Warrant. The
Company will supply from time to time the Transfer Agent with duly executed
stock certificates required to honor the outstanding Warrant.

     Section 8.  Adjustments.  Subject and pursuant to the provisions of this
                 -----------
Section 8, the Warrant Price and number of Warrant Shares subject to this
Warrant shall be subject to adjustment from time to time as set forth
hereinafter.

           (a)  If the Company shall at any time or from time to time while the
     Warrant is outstanding, pay a dividend or make a distribution on its Common
     Stock in shares of Common Stock, subdivide its outstanding shares of Common
     Stock into a greater number of shares or combine its outstanding shares
     into a smaller number of shares or issue by reclassification of its
     outstanding shares of Common Stock any shares of its capital stock
     (including any such reclassification in connection with a consolidation or
     merger in which the

                                       3
<PAGE>

     Company is the continuing corporation), then the number of Warrant Shares
     purchasable upon exercise of the Warrant and the Warrant Price in effect
     immediately prior to the date upon which such change shall become
     effective, shall be adjusted by the Company so that the Warrantholder
     thereafter exercising the Warrant shall be entitled to receive the number
     of shares of Common Stock or other capital stock which the Warrantholder
     would have received if the Warrant had been exercised immediately prior to
     such event. Such adjustment shall be made successively whenever any event
     listed above shall occur.

           (b)  If any capital reorganization, reclassification of the capital
     stock of the Company, consolidation or merger of the Company with another
     corporation in which the Company is not the survivor, or sale, transfer or
     other disposition of all or substantially all of the Company's properties
     to another corporation shall be effected, then, as a condition of such
     reorganization, reclassification, consolidation, merger, sale, transfer or
     other disposition, lawful and adequate provision shall be made whereby each
     Warrantholder shall thereafter have the right to purchase and receive upon
     the basis and upon the terms and conditions herein specified and in lieu of
     the Warrant Shares immediately theretofore issuable upon exercise of the
     Warrant, such shares of stock, securities or properties as would have been
     issuable or payable with respect to or in exchange for a number of Warrant
     Shares equal to the number of Warrant Shares immediately theretofore
     issuable upon exercise of the Warrant, had such reorganization,
     reclassification, consolidation, merger, sale, transfer or other
     disposition not taken place, and in any such case appropriate provision
     shall be made with respect to the rights and interests of each
     Warrantholder to the end that the provisions hereof (including, without
     limitations, provision for adjustment of the Warrant Price) shall
     thereafter be applicable, as nearly equivalent as may be practicable in
     relation to any shares of stock, securities or properties thereafter
     deliverable upon the exercise thereof. The Company shall not effect any
     such consolidation, merger, sale, transfer or other disposition unless
     prior to or simultaneously with the consummation thereof the successor
     corporation (if other than the Company) resulting from such consolidation
     or merger, or the corporation purchasing or otherwise acquiring such assets
     or other appropriate corporation or entity shall assume the obligation to
     deliver to the holder of the Warrant such shares of stock, securities or
     assets as, in accordance with the foregoing provisions, such holder may be
     entitled to purchase and the other obligations under this Warrant. The
     provisions of this paragraph (b) shall similarly apply to successive
     reorganizations, reclassifications, consolidations, mergers, sales,
     transfers or other dispositions.

           (c)  In case the Company shall fix a payment date for the making of a
     distribution to all holders of Common Stock (including any such
     distribution made in connection with a consolidation or merger in which the
     Company is the continuing corporation) of evidences of indebtedness or
     assets (other than cash dividends or cash distributions payable out of
     consolidated earnings or earned surplus or dividends or distributions
     referred to in Section 8(a)), or subscription rights or warrants, the
     Warrant Price to be in effect after such payment date shall be determined
     by multiplying the Warrant Price in effect immediately prior to such
     payment date by a fraction, the numerator of which shall be the total
     number of shares of Common Stock outstanding multiplied by the Market Price

                                       4
<PAGE>

     per share of Common Stock (as determined pursuant to Section 3), less the
     fair market value (as determined by the Company's Board of Directors in
     good faith) of said assets or evidences of indebtedness so distributed, or
     of such subscription rights or warrants, and the denominator of which shall
     be the total number of shares of Common Stock outstanding multiplied by
     such Market Price per share of Common Stock. Such adjustment shall be made
     successively whenever such a payment date is fixed.

           (d)  If pursuant to the Purchase Agreement by and between the Company
     and the Investor named therein dated June 8, 1999 (the "Purchase
     Agreement") there is an adjustment to the Purchase Price under Section
     7.1(a), then the Warrant Price shall be reduced to a price equal to 110% of
     such per share adjusted Purchase Price. Such adjustments shall be made
     successively whenever required.

           (e)  An adjustment shall become effective immediately after the
     payment date in the case of each dividend or distribution and immediately
     after the effective date of each other event which requires an adjustment.

           (f)  In the event that, as a result of an adjustment made pursuant to
     Section 8(a), the holder of the Warrant shall become entitled to receive
     any shares of capital stock of the Company other than shares of Common
     Stock, the number of such other shares so receivable upon exercise of the
     Warrant shall be subject thereafter to adjustment from time to time in a
     manner and on terms as nearly equivalent as practicable to the provisions
     with respect to the Warrant Shares contained in this Warrant.

     Section 9.  Fractional Interest.  The Company shall not be required to
                 -------------------
issue fractions of Warrant Shares upon the exercise of the Warrant. If any
fraction of a Warrant Share would, except for the provisions of this Section, be
issuable upon the exercise of the Warrant (or specified portions thereof), the
fractional share shall be disregarded and the number of shares to be issued upon
exercise shall be the number of whole shares only.

     Section 10.  Benefits.  Nothing in this Warrant shall be construed to give
                  --------
any person, firm or corporation (other than the Company and the Warrantholder)
any legal or equitable right, remedy or claim, it being agreed that this Warrant
shall be for the sole and exclusive benefit of the Company and the
Warrantholder.

     Section 11.  Notices to Warrantholder.  Upon the happening of any event
                  ------------------------
requiring an adjustment of the Warrant Price, the Company shall forthwith give
written notice thereof to the Warrantholder at the address appearing in the
records of the Company, stating the adjusted Warrant Price and the adjusted
number of Warrant Shares resulting from such event and setting forth in
reasonable detail the method of calculation and the facts upon which such
calculation is based. The certificate of the Company's independent certified
public accountants shall be conclusive evidence of the correctness of any
computation made, absent manifest error. Failure to give such notice to the
Warrantholder or any defect therein shall not affect the legality or validity of
the subject adjustment.

                                       5
<PAGE>

     Section 12.  Identity of Transfer Agent.  The Transfer Agent for the Common
                  --------------------------
Stock is American Stock Transfer & Trust Company, 40 Wall Street, New York,
New York 10005. Forthwith upon the appointment of any subsequent transfer agent
for the Common Stock or other shares of the Company's capital stock issuable
upon the exercise of the rights of purchase represented by the Warrant, the
Company will mail to the Warrantholder a statement setting forth the name and
address of such transfer agent.

     Section 13.  Notices.  Any notice pursuant hereto to be given or made by
                  -------
the Warrantholder to or on the Company shall be sufficiently given or made if
sent by certified mail, return receipt requested, postage prepaid, addressed as

     THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE
ABSENCE OF A REGISTRATION STATEMENT COVERING THIS WARRANT UNDER SAID ACT OR AN
EXEMPTION FROM REGISTRATION UNDER SAID ACT.

     VOID AFTER 5:00 P.M. EASTERN TIME ON JUNE 9, 2003  ("EXPIRATION DATE").


                             CAMBRIDGE HEART, INC.

                      WARRANT TO PURCHASE 5,771 SHARES OF
           COMMON STOCK, PAR VALUE $0.001 PER SHARE ("COMMON STOCK")

       For VALUE RECEIVED, Special Situations Fund III, L.P. ("Warrantholder"),
is entitled to purchase, subject to the provisions of this Warrant, from
Cambridge Heart, Inc., a Delaware corporation ("Company"), at any time not later
than 5:00 P.M., Eastern time, on the Expiration Date, at an exercise price per
share equal to $7.22 (the exercise price in effect being herein called the
"Warrant Price"), 5,771 shares ("Warrant Shares") of Common Stock. The number of
Warrant Shares purchasable upon exercise of this Warrant and the Warrant Price
shall be subject to adjustment from time to time as described herein.

       Section 1. Registration. The Company shall maintain books for the
                  ------------
transfer and registration of the Warrant. Upon the initial issuance of the
Warrant, the Company shall issue and register the Warrant in the name of the
Warrantholder.

       Section 2. Transfers. As provided herein, the Warrant may be transferred
                  ---------
only pursuant to a registration statement filed under the Securities
Act of 1933, as amended ("Securities Act") or an exemption from registration
thereunder. Subject to such restrictions, the Company shall transfer the Warrant
from time to time upon the books to be maintained by the Company for that
purpose, upon surrender thereof for transfer properly endorsed or accompanied by
appropriate instructions for transfer upon any such transfer, and a new Warrant
shall be issued to the transferee and the surrendered Warrant shall be canceled
by the Company.

       Section 3.  Exercise of Warrant.  Subject to the provisions hereof, the
                   -------------------
Warrantholder may exercise the Warrant in whole or in part at any time upon
surrender of the Warrant, together with delivery of the duly executed Warrant
exercise form attached hereto (the "Exercise Agreement"), to the Company during
normal business hours on any business day at the Company's principal executive
offices (or such other office or agency of the Company as it may designate by
notice to the holder hereof).  The Warrantholder will not be required to make
any cash payment upon exercise hereunder, but shall only be entitled to effect a
cashless exercise of this Warrant for that number of Warrant Shares indicated in
the Exercise
<PAGE>

Agreement. The Warrant Shares so purchased shall be deemed to be issued to the
holder hereof or such holder's designee, as the record owner of such shares, as
of the close of business on the date on which this Warrant shall have been
surrendered (or evidence of loss, theft or destruction thereof and security or
indemnity satisfactory to the Company) and the completed Exercise Agreement
shall have been delivered. Certificates for the Warrant Shares so purchased,
representing the aggregate number of shares specified in the Exercise Agreement,
shall be delivered to the holder hereof within a reasonable time, not exceeding
ten (10) business days, after this Warrant shall have been so exercised. The
certificates so delivered shall be in such denominations as may be requested by
the holder hereof and shall be registered in the name of such holder or such
other name as shall be designated by such holder. If this Warrant shall have
been exercised only in part, then, unless this Warrant has expired, the Company
shall, at its expense, at the time of delivery of such certificates, deliver to
the holder a new Warrant representing the number of shares with respect to which
this Warrant shall not then have been exercised.

        To effect the cashless exercise, the Warrantholder shall include in the
Exercise Agreement a calculation of the number of shares of Common Stock to be
issued determined by multiplying the number of Warrant Shares to which it would
otherwise be entitled by a fraction, the numerator of which shall be the
difference between the Market Price per share of the Common Stock on the date of
exercise and the Warrant Price, and the denominator of which shall be such
Market Price per share of the Common Stock.  For this purpose, the "Market
Price" of the Common Stock shall be the closing price of the Common Stock as
reported by the Nasdaq National Market on the trading day first preceding the
date in question.

       Each exercise hereof shall constitute the representation and warranty of
the Warrantholder to the Company that the representations and warranties
contained in Article 5 of the Purchase Agreement (as defined below) are true and
correct in all material respects as of the time of such exercise.

       Section 4. Compliance with the Securities Act of 1933. Neither this
                  ------------------------------------------
Warrant nor the Common Stock issued upon exercise hereof nor any other security
issued or issuable upon exercise of this Warrant may be offered or sold except
as provided in this agreement and in conformity with the Securities Act, and
then only against receipt of an agreement of such person to whom such offer of
sale is made to comply with the provisions of this Section 4 with respect to any
resale or other disposition of such security. The Company may cause the legend
set forth on the first page of this Warrant to be set forth on each Warrant or
similar legend on any security issued or issuable upon exercise of this Warrant,
unless counsel for the Company is of the opinion as to any such security that
such legend is unnecessary.

       Section 5.  Payment of Taxes.  The Company will pay any documentary stamp
                   ----------------
taxes attributable to the initial issuance of Warrant Shares issuable upon the
exercise of the Warrant; provided, however, that the Company shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issue or delivery of any

                                       2
<PAGE>

certificates for Warrant Shares in a name other than that of the registered
holder of the Warrant in respect of which such shares are issued, and in such
case, the Company shall not be required to issue or deliver any certificate for
Warrant Shares or any Warrant until the person requesting the same has paid to
the Company the amount of such tax or has established to the Company's
satisfaction that such tax has been paid. The holder shall be responsible for
income taxes due under federal or state law, if any such tax is due.

       Section 6.  Mutilated or Missing Warrants.  In case the Warrant shall be
                   -----------------------------
mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and
substitution of and upon cancellation of the mutilated Warrant, or in lieu of
and substitution for the Warrant lost, stolen or destroyed, a new Warrant of
like tenor and for the purchase of a like number of Warrant Shares, but only
upon receipt of evidence reasonably satisfactory to the Company of such loss,
theft or destruction of the Warrant, and with respect to a lost, stolen or
destroyed Warrant, reasonable indemnity or bond, if requested by the Company.

       Section 7. Reservation of Common Stock. The Company hereby represents and
                  ---------------------------
warrants that there have been reserved, and the Company shall at all applicable
times keep reserved until issued (if necessary) as contemplated by this Section
7, out of the authorized and unissued Common Stock, sufficient shares to provide
for the exercise of the rights of purchase represented by the Warrant. The
Company further represents and warrants that the transfer agent for the Common
Stock ("Transfer Agent"), and every subsequent transfer agent for the Common
Stock or other shares of the Company's capital stock issuable upon the exercise
of any of the right of purchase or conversion aforesaid, shall be irrevocably
authorized and directed at all times to issue such number of authorized and
unissued shares of Common Stock as shall be issuable upon the proper exercise
hereof. The Company agrees that all Warrant Shares issued upon exercise of the
Warrant shall be, at the time of delivery of the certificates for such Warrant
Shares, duly authorized, validly issued, fully paid and non-assessable shares of
Common Stock of the Company. The Company will keep a conformed copy of this
Warrant on file with the Transfer Agent and with every subsequent transfer agent
for the Common Stock or other shares of the Company's capital stock issuable
upon the exercise of the rights of purchase represented by the Warrant. The
Company will supply from time to time the Transfer Agent with duly executed
stock certificates required to honor the outstanding Warrant.

       Section 8.  Adjustments.  Subject and pursuant to the provisions of this
                   -----------
Section 8, the Warrant Price and number of Warrant Shares subject to this
Warrant shall be subject to adjustment from time to time as set forth
hereinafter.

       (a) If the Company shall at any time or from time to time while the
Warrant is outstanding, pay a dividend or make a distribution on its Common
Stock in shares of Common Stock, subdivide its outstanding shares of Common
Stock into a greater number of shares or combine its outstanding shares into a
smaller number of shares or issue by reclassification of its outstanding shares
of Common Stock any shares of its capital stock (including any such
reclassification in connection with a consolidation or merger in which the

                                       3
<PAGE>

Company is the continuing corporation), then the number of Warrant Shares
purchasable upon exercise of the Warrant and the Warrant Price in effect
immediately prior to the date upon which such change shall become effective,
shall be adjusted by the Company so that the Warrantholder thereafter exercising
the Warrant shall be entitled to receive the number of shares of Common Stock or
other capital stock which the Warrantholder would have received if the Warrant
had been exercised immediately prior to such event. Such adjustment shall be
made successively whenever any event listed above shall occur.

       (b) If any capital reorganization, reclassification of the capital stock
of the Company, consolidation or merger of the Company with another corporation
in which the Company is not the survivor, or sale, transfer or other disposition
of all or substantially all of the Company's properties to another corporation
shall be effected, then, as a condition of such reorganization,
reclassification, consolidation, merger, sale, transfer or other disposition,
lawful and adequate provision shall be made whereby each Warrantholder shall
thereafter have the right to purchase and receive upon the basis and upon the
terms and conditions herein specified and in lieu of the Warrant Shares
immediately theretofore issuable upon exercise of the Warrant, such shares of
stock, securities or properties as would have been issuable or payable with
respect to or in exchange for a number of Warrant Shares equal to the number of
Warrant Shares immediately theretofore issuable upon exercise of the Warrant,
had such reorganization, reclassification, consolidation, merger, sale, transfer
or other disposition not taken place, and in any such case appropriate provision
shall be made with respect to the rights and interests of each Warrantholder to
the end that the provisions hereof (including, without limitations, provision
for adjustment of the Warrant Price) shall thereafter be applicable, as nearly
equivalent as may be practicable in relation to any shares of stock, securities
or properties thereafter deliverable upon the exercise thereof. The Company
shall not effect any such consolidation, merger, sale, transfer or other
disposition unless prior to or simultaneously with the consummation thereof the
successor corporation (if other than the Company) resulting from such
consolidation or merger, or the corporation purchasing or otherwise acquiring
such assets or other appropriate corporation or entity shall assume the
obligation to deliver to the holder of the Warrant such shares of stock,
securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to purchase and the other obligations under this Warrant.
The provisions of this paragraph (b) shall similarly apply to successive
reorganizations, reclassifications, consolidations, mergers, sales, transfers or
other dispositions.

       (c) In case the Company shall fix a payment date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness or assets (other than cash
dividends or cash distributions payable out of consolidated earnings or earned
surplus or dividends or distributions referred to in Section 8(a)), or
subscription rights or warrants, the Warrant Price to be in effect after such
payment date shall be determined by multiplying the Warrant Price in effect
immediately prior to such payment date by a fraction, the numerator of which
shall be the total number of shares of Common Stock outstanding multiplied by
the Market Price

                                       4
<PAGE>

per share of Common Stock (as determined pursuant to Section 3), less the fair
market value (as determined by the Company's Board of Directors in good faith)
of said assets or evidences of indebtedness so distributed, or of such
subscription rights or warrants, and the denominator of which shall be the total
number of shares of Common Stock outstanding multiplied by such Market Price per
share of Common Stock. Such adjustment shall be made successively whenever such
a payment date is fixed.

       (d) If pursuant to the Purchase Agreement by and between the Company and
the Investor named therein dated June 8, 1999 (the "Purchase Agreement") there
is an adjustment to the Purchase Price under Section 7.1(a), then the Warrant
Price shall be reduced to a price equal to 110% of such per share adjusted
Purchase Price. Such adjustments shall be made successively whenever required.

       (e) An adjustment shall become effective immediately after the payment
date in the case of each dividend or distribution and immediately after the
effective date of each other event which requires an adjustment.

       (f) In the event that, as a result of an adjustment made pursuant to
Section 8(a), the holder of the Warrant shall become entitled to receive any
shares of capital stock of the Company other than shares of Common Stock, the
number of such other shares so receivable upon exercise of the Warrant shall be
subject thereafter to adjustment from time to time in a manner and on terms as
nearly equivalent as practicable to the provisions with respect to the Warrant
Shares contained in this Warrant.

       Section 9. Fractional Interest. The Company shall not be required to
                  -------------------
issue fractions of Warrant Shares upon the exercise of the Warrant. If any
fraction of a Warrant Share would, except for the provisions of this Section, be
issuable upon the exercise of the Warrant (or specified portions thereof), the
fractional share shall be disregarded and the number of shares to be issued upon
exercise shall be the number of whole shares only.

       Section 10. Benefits. Nothing in this Warrant shall be construed to give
                   --------
any person, firm or corporation (other than the Company and the Warrantholder)
any legal or equitable right, remedy or claim, it being agreed that this Warrant
shall be for the sole and exclusive benefit of the Company and the
Warrantholder.

       Section 11.  Notices to Warrantholder.  Upon the happening of any event
                    ------------------------
requiring an adjustment of the Warrant Price, the Company shall forthwith give
written notice thereof to the Warrantholder at the address appearing in the
records of the Company, stating the adjusted Warrant Price and the adjusted
number of Warrant Shares resulting from such event and setting forth in
reasonable detail the method of calculation and the facts upon which such
calculation is based.  The certificate of the Company's independent certified
public accountants shall be conclusive evidence of the correctness of any
computation made, absent manifest error.  Failure to give such notice to the
Warrantholder or any defect therein shall not affect the legality or validity of
the subject adjustment.

                                       5
<PAGE>

       Section 12. Identity of Transfer Agent. The Transfer Agent for the Common
                   --------------------------
Stock is American Stock Transfer & Trust Company, 40 Wall Street, NewYork, New
YOrk 10005. Forthwith upon the appointment of any subsequent transfer agent for
the Common Stock or other shares of the Company's capital stock issuable upon
the exercise of the rights of purchase represented by the Warrant, the Company
will mail to the Warrantholder a statement setting forth the name and address of
such transfer agent.

       Section 13. Notices. Any notice pursuant hereto to be given or made by
                   -------
the Warrantholder to or on the Company shall be sufficiently given or made if
sent by certified mail, return receipt requested, postage prepaid, addressed as

delivery with the terms of this Section 13. All such notices, requests, demands,
directions and other communications shall, when sent by courier be effective
three (3) days after delivery to such courier as provided and addressed as

       Section 14.  Registration Rights.  The initial holder of this Warrant is
                    -------------------
entitled to the benefit of certain registration rights in respect of the Warrant
Shares as provided in the Registration Rights Agreement dated as of as of June

       Section 15. Successors. All the covenants and provisions hereof by or for

respective successors and assigns hereunder.

       Section 16. Governing Law. This Warrant shall be deemed to be a contract
                   -------------

     THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE
ABSENCE OF A REGISTRATION STATEMENT COVERING THIS WARRANT UNDER SAID ACT OR AN

     VOID AFTER 5:00 P.M. EASTERN TIME ON JUNE 9, 2003  ("EXPIRATION DATE").


                             CAMBRIDGE HEART, INC.

                     WARRANT  TO PURCHASE 22,800 SHARES OF
           COMMON STOCK, PAR VALUE $0.001 PER SHARE ("COMMON STOCK")

     For VALUE RECEIVED, Special Situations Private Equity Fund, L.P.
("Warrantholder"), is entitled to purchase, subject to the provisions of this
Warrant, from Cambridge Heart, Inc., a Delaware corporation ("Company"), at any
time not later than 5:00 P.M., Eastern time, on the Expiration Date, at an
exercise price per share equal to $7.22 (the exercise price in effect being
herein called the "Warrant Price"), 22,800 shares ("Warrant Shares") of Common
Stock. The number of Warrant Shares purchasable upon exercise of this Warrant
and the Warrant Price shall be subject to adjustment from time to time as
described herein.

     Section 1.  Registration.  The Company shall maintain books for the
                 ------------
transfer and registration of the Warrant. Upon the initial issuance of the
Warrant, the Company shall issue and register the Warrant in the name of the
Warrantholder.

     Section 2.  Transfers.  As provided herein, the Warrant may be transferred
                 ---------
only pursuant to a registration statement filed under the Securities Act of
1933, as amended ("Securities Act") or an exemption from registration
thereunder. Subject to such restrictions, the Company shall transfer the Warrant
from time to time upon the books to be maintained by the Company for that
purpose, upon surrender thereof for transfer properly endorsed or accompanied by
appropriate instructions for transfer upon any such transfer, and a new Warrant
shall be issued to the transferee and the surrendered Warrant shall be canceled
by the Company.

     Section 3.  Exercise of Warrant.  Subject to the provisions hereof, the
                 -------------------
Warrantholder may exercise the Warrant in whole or in part at any time upon
surrender of the Warrant, together with delivery of the duly executed Warrant
exercise form attached hereto (the "Exercise Agreement"), to the Company during
normal business hours on any business day at the Company's principal executive
offices (or such other office or agency of the Company as it may designate by
notice to the holder hereof). The Warrantholder will not be required to make any
cash payment upon exercise hereunder, but shall only be entitled to effect a
cashless exercise of this Warrant for that number of Warrant Shares indicated in
the Exercise Agreement.
<PAGE>

The Warrant Shares so purchased shall be deemed to be issued to the holder
hereof or such holder's designee, as the record owner of such shares, as of the
close of business on the date on which this Warrant shall have been surrendered
(or evidence of loss, theft or destruction thereof and security or indemnity
satisfactory to the Company) and the completed Exercise Agreement shall have
been delivered. Certificates for the Warrant Shares so purchased, representing
the aggregate number of shares specified in the Exercise Agreement, shall be
delivered to the holder hereof within a reasonable time, not exceeding ten (10)
business days, after this Warrant shall have been so exercised. The certificates
so delivered shall be in such denominations as may be requested by the holder
hereof and shall be registered in the name of such holder or such other name as
shall be designated by such holder. If this Warrant shall have been exercised
only in part, then, unless this Warrant has expired, the Company shall, at its
expense, at the time of delivery of such certificates, deliver to the holder a
new Warrant representing the number of shares with respect to which this Warrant
shall not then have been exercised.

     To effect the cashless exercise, the Warrantholder shall include in the
Exercise Agreement a calculation of the number of shares of Common Stock to be
issued determined by multiplying the number of Warrant Shares to which it would
otherwise be entitled by a fraction, the numerator of which shall be the
difference between the Market Price per share of the Common Stock on the date of
exercise and the Warrant Price, and the denominator of which shall be such
Market Price per share of the Common Stock. For this purpose, the "Market Price"
of the Common Stock shall be the closing price of the Common Stock as reported
by the Nasdaq National Market on the trading day first preceding the date in
question.

     Each exercise hereof shall constitute the representation and warranty of
the Warrantholder to the Company that the representations and warranties
contained in Article 5 of the Purchase Agreement (as defined below) are true and
correct in all material respects as of the time of such exercise.

     Section 4.  Compliance with the Securities Act of 1933.  Neither this
                 ------------------------------------------
Warrant nor the Common Stock issued upon exercise hereof nor any other security
issued or issuable upon exercise of this Warrant may be offered or sold except
as provided in this agreement and in conformity with the Securities Act, and
then only against receipt of an agreement of such person to whom such offer of
sale is made to comply with the provisions of this Section 4 with respect to any
resale or other disposition of such security. The Company may cause the legend
set forth on the first page of this Warrant to be set forth on each Warrant or
similar legend on any security issued or issuable upon exercise of this Warrant,
unless counsel for the Company is of the opinion as to any such security that
such legend is unnecessary.

     Section 5.  Payment of Taxes.  The Company will pay any documentary stamp
                 ----------------
taxes attributable to the initial issuance of Warrant Shares issuable upon the
exercise of the Warrant; provided, however, that the Company shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issue or delivery of any
<PAGE>

certificates for Warrant Shares in a name other than that of the registered
holder of the Warrant in respect of which such shares are issued, and in such
case, the Company shall not be required to issue or deliver any certificate for
Warrant Shares or any Warrant until the person requesting the same has paid to
the Company the amount of such tax or has established to the Company's
satisfaction that such tax has been paid. The holder shall be responsible for
income taxes due under federal or state law, if any such tax is due.

     Section 6.  Mutilated or Missing Warrants.  In case the Warrant shall be
                 -----------------------------
mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and
substitution of and upon cancellation of the mutilated Warrant, or in lieu of
and substitution for the Warrant lost, stolen or destroyed, a new Warrant of
like tenor and for the purchase of a like number of Warrant Shares, but only
upon receipt of evidence reasonably satisfactory to the Company of such loss,
theft or destruction of the Warrant, and with respect to a lost, stolen or
destroyed Warrant, reasonable indemnity or bond, if requested by the Company.

     Section 7.  Reservation of Common Stock.  The Company hereby represents and
                 ---------------------------
warrants that there have been reserved, and the Company shall at all applicable
times keep reserved until issued (if necessary) as contemplated by this Section
7, out of the authorized and unissued Common Stock, sufficient shares to provide
for the exercise of the rights of purchase represented by the Warrant. The
Company further represents and warrants that the transfer agent for the Common
Stock ("Transfer Agent"), and every subsequent transfer agent for the Common
Stock or other shares of the Company's capital stock issuable upon the exercise
of any of the right of purchase or conversion aforesaid, shall be irrevocably
authorized and directed at all times to issue such number of authorized and
unissued shares of Common Stock as shall be issuable upon the proper exercise
hereof. The Company agrees that all Warrant Shares issued upon exercise of the
Warrant shall be, at the time of delivery of the certificates for such Warrant
Shares, duly authorized, validly issued, fully paid and non-assessable shares of
Common Stock of the Company. The Company will keep a conformed copy of this
Warrant on file with the Transfer Agent and with every subsequent transfer agent
for the Common Stock or other shares of the Company's capital stock issuable
upon the exercise of the rights of purchase represented by the Warrant. The
Company will supply from time to time the Transfer Agent with duly executed
stock certificates required to honor the outstanding Warrant.

     Section 8.  Adjustments.  Subject and pursuant to the provisions of this
                 -----------
Section 8, the Warrant Price and number of Warrant Shares subject to this
Warrant shall be subject to adjustment from time to time as set forth
hereinafter.

                (a)  If the Company shall at any time or from time to time while
the Warrant is outstanding, pay a dividend or make a distribution on its Common
Stock in shares of Common Stock, subdivide its outstanding shares of Common
Stock into a greater number of shares or combine its outstanding shares into a
smaller number of shares or issue by reclassification of its outstanding shares
of Common Stock any shares of its capital stock (including any such
reclassification in connection with a consolidation or merger in which the
<PAGE>

Company is the continuing corporation), then the number of Warrant Shares
purchasable upon exercise of the Warrant and the Warrant Price in effect
immediately prior to the date upon which such change shall become effective,
shall be adjusted by the Company so that the Warrantholder thereafter exercising
the Warrant shall be entitled to receive the number of shares of Common Stock or
other capital stock which the Warrantholder would have received if the Warrant
had been exercised immediately prior to such event. Such adjustment shall be
made successively whenever any event listed above shall occur.

                (b) If any capital reorganization, reclassification of the
capital stock of the Company, consolidation or merger of the Company with
another corporation in which the Company is not the survivor, or sale, transfer
or other disposition of all or substantially all of the Company's properties to
another corporation shall be effected, then, as a condition of such
reorganization, reclassification, consolidation, merger, sale, transfer or other
disposition, lawful and adequate provision shall be made whereby each
Warrantholder shall thereafter have the right to purchase and receive upon the
basis and upon the terms and conditions herein specified and in lieu of the
Warrant Shares immediately theretofore issuable upon exercise of the Warrant,
such shares of stock, securities or properties as would have been issuable or
payable with respect to or in exchange for a number of Warrant Shares equal to
the number of Warrant Shares immediately theretofore issuable upon exercise of
the Warrant, had such reorganization, reclassification, consolidation, merger,
sale, transfer or other disposition not taken place, and in any such case
appropriate provision shall be made with respect to the rights and interests of
each Warrantholder to the end that the provisions hereof (including, without
limitations, provision for adjustment of the Warrant Price) shall thereafter be
applicable, as nearly equivalent as may be practicable in relation to any shares
of stock, securities or properties thereafter deliverable upon the exercise
thereof. The Company shall not effect any such consolidation, merger, sale,
transfer or other disposition unless prior to or simultaneously with the
consummation thereof the successor corporation (if other than the Company)
resulting from such consolidation or merger, or the corporation purchasing or
otherwise acquiring such assets or other appropriate corporation or entity shall
assume the obligation to deliver to the holder of the Warrant such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to purchase and the other obligations under this
Warrant. The provisions of this paragraph (b) shall similarly apply to
successive reorganizations, reclassifications, consolidations, mergers, sales,
transfers or other dispositions.

                (c)  In case the Company shall fix a payment date for the making
of a distribution to all holders of Common Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of evidences of indebtedness or assets
(other than cash dividends or cash distributions payable out of consolidated
earnings or earned surplus or dividends or distributions referred to in Section
8(a)), or subscription rights or warrants, the Warrant Price to be in effect
after such payment date shall be determined by multiplying the Warrant Price in
effect immediately prior to such payment date by a fraction, the numerator of
which shall be the total number of shares of Common Stock outstanding multiplied
by the Market Price
<PAGE>

per share of Common Stock (as determined pursuant to Section 3), less the fair
market value (as determined by the Company's Board of Directors in good faith)
of said assets or evidences of indebtedness so distributed, or of such
subscription rights or warrants, and the denominator of which shall be the total
number of shares of Common Stock outstanding multiplied by such Market Price per
share of Common Stock. Such adjustment shall be made successively whenever such
a payment date is fixed.

                (d)  If pursuant to the Purchase Agreement by and between the
Company and the Investor named therein dated June 8, 1999 (the "Purchase
Agreement") there is an adjustment to the Purchase Price under Section 7.1(a),
then the Warrant Price shall be reduced to a price equal to 110% of such per
share adjusted Purchase Price. Such adjustments shall be made successively
whenever required.

                (e)  An adjustment shall become effective immediately after the
payment date in the case of each dividend or distribution and immediately after
the effective date of each other event which requires an adjustment.

                (f)  In the event that, as a result of an adjustment made
pursuant to Section 8(a), the holder of the Warrant shall become entitled to
receive any shares of capital stock of the Company other than shares of Common
Stock, the number of such other shares so receivable upon exercise of the
Warrant shall be subject thereafter to adjustment from time to time in a manner
and on terms as nearly equivalent as practicable to the provisions with respect
to the Warrant Shares contained in this Warrant.

     Section 9.  Fractional Interest.  The Company shall not be required to
                 -------------------
issue fractions of Warrant Shares upon the exercise of the Warrant. If any
fraction of a Warrant Share would, except for the provisions of this Section, be
issuable upon the exercise of the Warrant (or specified portions thereof), the
fractional share shall be disregarded and the number of shares to be issued upon
exercise shall be the number of whole shares only.

     Section 10.  Benefits.  Nothing in this Warrant shall be construed to give
                  --------
any person, firm or corporation (other than the Company and the Warrantholder)
any legal or equitable right, remedy or claim, it being agreed that this Warrant
shall be for the sole and exclusive benefit of the Company and the
Warrantholder.

     Section 11.  Notices to Warrantholder.  Upon the happening of any event
                  ------------------------
requiring an adjustment of the Warrant Price, the Company shall forthwith give
written notice thereof to the Warrantholder at the address appearing in the
records of the Company, stating the adjusted Warrant Price and the adjusted
number of Warrant Shares resulting from such event and setting forth in
reasonable detail the method of calculation and the facts upon which such
calculation is based. The certificate of the Company's independent certified
public accountants shall be conclusive evidence of the correctness of any
computation made, absent manifest error. Failure to give such notice to the
Warrantholder or any defect therein shall not affect the legality or validity of
the subject adjustment.
<PAGE>

     Section 12.  Identity of Transfer Agent.  The Transfer Agent for the Common
                  --------------------------
Stock is American Stock Transfer & Trust Company, 40 Wall Street, New York,
New York 10005. Forthwith upon the appointment of any subsequent transfer agent
for the Common Stock or other shares of the Company's capital stock issuable
upon the exercise of the rights of purchase represented by the Warrant, the
Company will mail to the Warrantholder a statement setting forth the name and
address of such transfer agent.

     Section 13.  Notices.  Any notice pursuant hereto to be given or made by
                  -------
the Warrantholder to or on the Company shall be sufficiently given or made if
sent by certified mail, return receipt requested, postage prepaid, addressed as

the terms of this Section 13. All such notices, requests, demands, directions
and other communications shall, when sent by courier be effective three (3) days
after delivery to such courier as provided and addressed as aforesaid.

     Section 14.  Registration Rights.  The initial holder of this Warrant is
                  -------------------
entitled to the benefit of certain registration rights in respect of the Warrant
Shares as provided in the Registration Rights Agreement dated as of as of
June 8, 1999.

     Section 15.   Successors.  All the covenants and provisions hereof by or
                   ----------
for the benefit of the Warrantholder shall bind and inure to the benefit of its
respective successors and assigns hereunder.

     Section 16.  Governing Law.  This Warrant shall be deemed to be a contract
                  --------------
made under the laws of the State of Delaware and for all purposes shall be

                             CAMBRIDGE HEART, INC.

                     WARRANT  TO PURCHASE 47,619 SHARES OF
           COMMON STOCK, PAR VALUE $0.001 PER SHARE ("Common Stock")

       For VALUE RECEIVED, The Tail Wind Fund Ltd. ("Warrantholder"), is
entitled to purchase, subject to the provisions of this Warrant, from Cambridge
Heart, Inc., a Delaware corporation ("Company"), at any time not later than 5:00
P.M., Eastern time, on the Expiration Date, at an exercise price per share equal
to $7.22 (the exercise price in effect being herein called the "Warrant Price"),
47,619 shares ("Warrant Shares") of Common Stock. The number of Warrant Shares
purchasable upon exercise of this Warrant and the Warrant Price shall be subject
to adjustment from time to time as described herein.

       Section 1. Registration. The Company shall maintain books for the
                  ------------
transfer and registration of the Warrant. Upon the initial issuance of the
Warrant, the Company shall issue and register the Warrant in the name of the
Warrantholder.

       Section 2. Transfers. As provided herein, the Warrant may be transferred
                  ---------
only pursuant to a registration statement filed under the Securities Act of
1933, as amended ("Securities Act") or an exemption from registration
thereunder. Subject to such restrictions, the Company shall transfer the Warrant

purpose, upon surrender thereof for transfer properly endorsed or accompanied by
appropriate instructions for transfer upon any such transfer, and a new Warrant
shall be issued to the transferee and the surrendered Warrant shall be canceled
by the Company.

       Section 3. Exercise of Warrant.  Subject to the provisions hereof, the
                  -------------------
Warrantholder may exercise the Warrant in whole or in part at any time upon
surrender of the Warrant, together with delivery of the duly executed Warrant
exercise form attached hereto (the "Exercise Agreement"), to the Company during
normal business hours on any business day at the Company's principal executive
offices (or such other office or agency of the Company as it may designate by
notice to the holder hereof).  The Warrantholder will not be required to make
any cash payment upon exercise hereunder, but shall only be entitled to effect a
cashless exercise of this Warrant for that number of Warrant Shares indicated in
the Exercise
<PAGE>

Agreement. The Warrant Shares so purchased shall be deemed to be issued to the
holder hereof or such a designee, as the record owner of such shares, as
of the close of business on the date on which this Warrant shall have been
surrendered (or evidence of loss, theft or destruction thereof and security or
indemnity satisfactory to the Company) and the completed Exercise Agreement
shall have been delivered. Certificates for the Warrant Shares so purchased,
representing the aggregate number of shares specified in the Exercise Agreement,
shall be delivered to the holder hereof within a reasonable time, not exceeding
ten (10) business days, after this Warrant shall have been so exercised. The
certificates so delivered shall be in such denominations as may be requested by
the holder hereof and shall be registered in the name of such holder or such
other name as shall be designated by such holder. If this Warrant shall have
been exercised only in part, then, unless this Warrant has expired, the Company
shall, at its expense, at the time of delivery of such certificates, deliver to
the holder a new Warrant representing the number of shares with respect to which
this Warrant shall not then have been exercised.

       To effect the cashless exercise, the Warrantholder shall include in the
Exercise Agreement a calculation of the number of shares of Common Stock to be
issued determined by multiplying the number of Warrant Shares to which it would
otherwise be entitled by a fraction, the numerator of which shall be the
difference between the Market Price per share of the Common Stock on the date of
exercise and the Warrant Price, and the denominator of which shall be such
Market Price per share of the Common Stock.  For this purpose, the "Market
Price" of the Common Stock shall be the closing price of the Common Stock as
reported by the Nasdaq National Market on the trading day first preceding the
date in question.

       Each exercise hereof shall constitute the representation and warranty of
the Warrantholder to the Company that the representations and warranties
contained in Article 5 of the Purchase Agreement (as defined below) are true and
correct in all material respects as of the time of such exercise.

       Section 4. Compliance with the Securities Act of 1933. Neither this
                  ------------------------------------------
Warrant nor the Common Stock issued upon exercise hereof nor any other security
issued or issuable upon exercise of this Warrant may be offered or sold except
as provided in this agreement and in conformity with the Securities Act, and
then only against receipt of an agreement of such person to whom such offer of
sale is made to comply with the provisions of this Section 4 with respect to any
resale or other disposition of such security. The Company may cause the legend
set forth on the first page of this Warrant to be set forth on each Warrant or
similar legend on any security issued or issuable upon exercise of this Warrant,
unless counsel for the Company is of the opinion as to any such security that
such legend is unnecessary.

       Section 5. Payment of Taxes.  The Company will pay any documentary stamp
                  ----------------
taxes attributable to the initial issuance of Warrant Shares issuable upon the
exercise of the Warrant; provided, however, that the Company shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issue or delivery of any

                                       2
<PAGE>

certificates for Warrant Shares in a name other than that of the registered
holder of the Warrant in respect of which such shares are issued, and in such
case, the Company shall not be required to issue or deliver any certificate for
Warrant Shares or any Warrant until the person requesting the same has paid to
the Company the amount of such tax or has established to the Company's
satisfaction that such tax has been paid. The holder shall be responsible for
income taxes due under federal or state law, if any such tax is due.

       Section 6. Mutilated or Missing Warrants.  In case the Warrant shall be
                  -----------------------------
mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and
substitution of and upon cancellation of the mutilated Warrant, or in lieu of
and substitution for the Warrant lost, stolen or destroyed, a new Warrant of
like tenor and for the purchase of a like number of Warrant Shares, but only
upon receipt of evidence reasonably satisfactory to the Company of such loss,
theft or destruction of the Warrant, and with respect to a lost, stolen or
destroyed Warrant, reasonable indemnity or bond, if requested by the Company.

       Section 7. Reservation of Common Stock. The Company hereby represents and
                  ---------------------------
warrants that there have been reserved, and the Company shall at all applicable
times keep reserved until issued (if necessary) as contemplated by this Section
7, out of the authorized and unissued Common Stock, sufficient shares to provide
for the exercise of the rights of purchase represented by the Warrant. The
Company further represents and warrants that the transfer agent for the Common
Stock ("Transfer Agent"), and every subsequent transfer agent for the Common
Stock or other shares of the Company's capital stock issuable upon the exercise
of any of the right of purchase or conversion aforesaid, shall be irrevocably
authorized and directed at all times to issue such number of authorized and
unissued shares of Common Stock as shall be issuable upon the proper exercise
hereof. The Company agrees that all Warrant Shares issued upon exercise of the
Warrant shall be, at the time of delivery of the certificates for such Warrant
Shares, duly authorized, validly issued, fully paid and non-assessable shares of
Common Stock of the Company. The Company will keep a conformed copy of this
Warrant on file with the Transfer Agent and with every subsequent transfer agent
for the Common Stock or other shares of the Company's capital stock issuable
upon the exercise of the rights of purchase represented by the Warrant. The
Company will supply from time to time the Transfer Agent with duly executed
stock certificates required to honor the outstanding Warrant.

       Section 8.  Adjustments.  Subject and pursuant to the provisions of this
                   -----------
Section 8, the Warrant Price and number of Warrant Shares subject to this
Warrant shall be subject to adjustment from time to time as set forth
hereinafter.

       (a) If the Company shall at any time or from time to time while the
 Warrant is outstanding, pay a dividend or make a distribution on its Common
 Stock in shares of Common Stock, subdivide its outstanding shares of Common
 Stock into a greater number of shares or combine its outstanding shares into a
 smaller number of shares or issue by reclassification of its outstanding shares
 of Common Stock any shares of its capital stock (including any such
 reclassification in connection with a consolidation or merger in which the

                                       3
<PAGE>

Company is the continuing corporation), then the number of Warrant Shares
purchasable upon exercise of the Warrant and the Warrant Price in effect
immediately prior to the date upon which such change shall become effective,
shall be adjusted by the Company so that the Warrantholder thereafter exercising
the Warrant shall be entitled to receive the number of shares of Common Stock or
other capital stock which the Warrantholder would have received if the Warrant
had been exercised immediately prior to such event. Such adjustment shall be
made successively whenever any event listed above shall occur.

       (b) If any capital reorganization, reclassification of the capital stock
of the Company, consolidation or merger of the Company with another corporation
in which the Company is not the survivor, or sale, transfer or other disposition
of all or substantially all of the Company's properties to another corporation
shall be effected, then, as a condition of such reorganization,
reclassification, consolidation, merger, sale, transfer or other disposition,
lawful and adequate provision shall be made whereby each Warrantholder shall
thereafter have the right to purchase and receive upon the basis and upon the
terms and conditions herein specified and in lieu of the Warrant Shares
immediately theretofore issuable upon exercise of the Warrant, such shares of
stock, securities or properties as would have been issuable or payable with
respect to or in exchange for a number of Warrant Shares equal to the number of
Warrant Shares immediately theretofore issuable upon exercise of the Warrant,
had such reorganization, reclassification, consolidation, merger, sale, transfer
or other disposition not taken place, and in any such case appropriate provision
shall be made with respect to the rights and interests of each Warrantholder to
the end that the provisions hereof (including, without limitations, provision
for adjustment of the Warrant Price) shall thereafter be applicable, as nearly
equivalent as may be practicable in relation to any shares of stock, securities
or properties thereafter deliverable upon the exercise thereof. The Company
shall not effect any such consolidation, merger, sale, transfer or other
disposition unless prior to or simultaneously with the consummation thereof the
successor corporation (if other than the Company) resulting from such
consolidation or merger, or the corporation purchasing or otherwise acquiring
such assets or other appropriate corporation or entity shall assume the
obligation to deliver to the holder of the Warrant such shares of stock,
securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to purchase and the other obligations under this Warrant.
The provisions of this paragraph (b) shall similarly apply to successive
reorganizations, reclassifications, consolidations, mergers, sales, transfers or
other dispositions.

       (c) In case the Company shall fix a payment date for the making of a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness or assets (other than cash
dividends or cash distributions payable out of consolidated earnings or earned
surplus or dividends or distributions referred to in Section 8(a)), or
subscription rights or warrants, the Warrant Price to be in effect after such
payment date shall be determined by multiplying the Warrant Price in effect
immediately prior to such payment date by a fraction, the numerator of which
shall be the total number of shares of Common Stock outstanding multiplied by
the Market Price

                                       4
<PAGE>

per share of Common Stock (as determined pursuant to Section 3), less the fair
market value (as determined by the Company's Board of Directors in good faith)
of said assets or evidences of indebtedness so distributed, or of such
subscription rights or warrants, and the denominator of which shall be the total
number of shares of Common Stock outstanding multiplied by such Market Price per
share of Common Stock. Such adjustment shall be made successively whenever such
a payment date is fixed.

       (d) If pursuant to the Purchase Agreement by and between the Company and
the Investor named therein dated June 8, 1999 (the "Purchase Agreement") there
is an adjustment to the Purchase Price under Section 7.1(a), then the Warrant
Price shall be reduced to a price equal to 110% of such per share adjusted
Purchase Price. Such adjustments shall be made successively whenever required.

       (e) An adjustment shall become effective immediately after the payment
date in the case of each dividend or distribution and immediately after the
effective date of each other event which requires an adjustment.

       (f) In the event that, as a result of an adjustment made pursuant to
Section 8(a), the holder of the Warrant shall become entitled to receive any
shares of capital stock of the Company other than shares of Common Stock, the
number of such other shares so receivable upon exercise of the Warrant shall be
subject thereafter to adjustment from time to time in a manner and on terms as
nearly equivalent as practicable to the provisions with respect to the Warrant
Shares contained in this Warrant.

       Section 9.  Fractional Interest. The Company shall not be required to
                   -------------------
issue fractions of Warrant Shares upon the exercise of the Warrant. If any
fraction of a Warrant Share would, except for the provisions of this Section, be
issuable upon the exercise of the Warrant (or specified portions thereof), the
fractional share shall be disregarded and the number of shares to be issued upon
exercise shall be the number of whole shares only.

       Section 10. Benefits. Nothing in this Warrant shall be construed to give
                   --------
any person, firm or corporation (other than the Company and the Warrantholder)
any legal or equitable right, remedy or claim, it being agreed that this Warrant
shall be for the sole and exclusive benefit of the Company and the
Warrantholder.

       Section 11. Notices to Warrantholder.  Upon the happening of any event
                   ------------------------
requiring an adjustment of the Warrant Price, the Company shall forthwith give
written notice thereof to the Warrantholder at the address appearing in the
records of the Company, stating the adjusted Warrant Price and the adjusted
number of Warrant Shares resulting from such event and setting forth in
reasonable detail the method of calculation and the facts upon which such
calculation is based.  The certificate of the Company's independent certified
public accountants shall be conclusive evidence of the correctness of any
computation made, absent manifest error.  Failure to give such notice to the
Warrantholder or any defect therein shall not affect the legality or validity of
the subject adjustment.

       Section 12. Identity of Transfer Agent. The Transfer Agent for the Common
                   --------------------------
Stock is American Stock Transfer & Trust Company, 40 Wall Street, New York, New
York 10005. Forthwith upon the appointment of any subsequent transfer agent for
the Common Stock or other shares of the Company's capital stock issuable upon
the exercise of the rights of purchase represented by the Warrant, the Company
will mail to the Warrantholder a statement setting forth the name and address of
such transfer agent.

Shares as provided in the Registration Rights Agreement dated as of as of
