ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Article Nine of the Registrant's Restated Certificate of Incorporation (the
"Restated Certificate of Incorporation") provides that no director of the
Registrant shall be personally liable for any monetary damages for any breach
of fiduciary duty as a director, except to the extent that the Delaware
General Corporation Law prohibits the elimination or limitation of liability
of directors for breach of fiduciary duty.
 
  Article Nine of the Registrant's Restated Certificate of Incorporation
provides that a director or officer of the Registrant (a) shall be indemnified
by the Registrant against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement incurred in connection with any
litigation or other legal proceeding (other than an action by or in the right
of the Registrant) brought against him by virtue of his position as a director
or officer of the Registrant if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Registrant, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful and (b) shall be
indemnified by the Registrant against all expenses (including attorneys' fees)
and amounts paid in settlement incurred in connection with any action by or in
the right of the Registrant brought against him by virtue of his position as a
director or officer of the Registrant if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests
of the Registrant, except that no indemnification shall be made with respect
to any matter as to which such person shall have been adjudged to be liable to
the Registrant, unless a court determines that, despite such adjudication but
in view of all of the circumstances, he is entitled to indemnification of such
expenses. Notwithstanding the foregoing, to the extent that a director or
officer has been successful, on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, he is required to be
indemnified by the Registrant against all expenses (including attorneys' fees)
incurred in connection therewith. Expenses shall be advanced to a director or
officer at his request, provided that he undertakes to repay the amount
advanced if it is ultimately determined that he is not entitled to
indemnification for such expenses.
 
                                     II-1
<PAGE>
 
  Indemnification is required to be made unless the Registrant determines that
the applicable standard of conduct required for indemnification has not been
met. In the event of a determination by the Registrant that the director or
officer did not meet the applicable standard of conduct required for
indemnification, or if the Registrant fails to make an indemnification payment
within 60 days after such payment is claimed by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent
to the right of indemnification, the director or officer must give the
Registrant notice of the action for which indemnity is sought and the
Registrant has the right to participate in such action or assume the defense
thereof.
 
  Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent
of the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred
in connection with an action or proceeding to which he is or is threatened to
be made a party by reason of such position, if such person shall have acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, in any criminal proceeding, if
such person had no reasonable cause to believe his conduct was unlawful;
provided that, in the case of actions brought by or in the right of the
corporation, no indemnification shall be made with respect to any matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the adjudicating court determines that such
indemnification is proper under the circumstances.
 
  Under Section Eight of the Underwriting Agreement, the Underwriters are
obligated, under certain circumstances, to indemnify directors and officers of
the Registrant against certain liabilities, including liabilities under the
Securities Act of 1933, as amended (the "Securities Act").

ITEM 17. UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions contained in the Restated Certificate of
Incorporation and Amended and Restated By-Laws of the Registrant and the laws
of the State of Delaware, or otherwise, the Registrant has been advised that
in the opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
 
  The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

                                CAMBRIDGE HEART, INC.
                                AMENDED AND RESTATED
                          1993 INCENTIVE AND NON-QUALIFIED
                                  STOCK OPTION PLAN


              1.   Purpose
                   -------

              The purpose of this Amended and Restated 1993 Incentive and

         Non-Qualified Stock Option Plan (the "Plan") is to encourage and

         enable selected management and other key employees of, or

         consultants to, Cambridge Heart, Inc. (the "Company") or a parent

         or subsidiary of the Company to acquire a proprietary interest in

         the Company through the ownership of common stock, par value $.001

         per share (the "Common Stock"), of the Company.  Such ownership

         will provide such persons with a more direct stake in the future

         welfare of the Company, and encourage them to remain with, or

         serve the Company or a parent or subsidiary of the Company.  It is

         also expected that the Plan will encourage qualified persons to

         seek and accept employment with the Company or a parent or

         subsidiary of the Company.  Pursuant to the Plan, such persons

         will be offered the opportunity to acquire such Common Stock

         through the grant of incentive stock options and "non-qualified"

         stock options.

              As used herein, the term "parent" or "subsidiary" shall mean

         any present or future corporation which is or would be a "parent

         corporation" or "subsidiary corporation" of the Company as the

         term is defined in Section 424(e) and 424(f) of the Internal

         Revenue Code of 1986, as amended (the "Code") (determined as if

         the Company were the employer corporation).

              2.   Administration of the Plan
                   --------------------------

              The Plan shall be administered by a Stock Option Committee

         (the "Committee") as appointed from time to time by the Board of

         Directors of the Company, which committee shall consist of not

         less than three members of the Board of Directors.  None of the
<PAGE>
 
         members of the Committee shall be, or shall have been within one

         year prior to their becoming a member, eligible to be granted

         options under the Plan.

              In administering the Plan, the Committee may adopt rules and

         regulations for carrying out the Plan.  The interpretations and

         decisions made by the Committee with regard to any question

         arising under the Plan shall be final and conclusive on all

         persons participating or eligible to participate in the Plan.

         Subject to the provisions of the Plan, the Committee shall

         determine the terms of all options granted pursuant to the Plan,

         including, but not limited to, the persons to whom, and the time

         or times at which, grants shall be made, the number of options to

         be included in the grants, the number of options which shall be

         treated as incentive stock options or designated as non-qualified

         stock options, the duration and vesting of such options, and the

         option price.

              3.   Shares of Stock Subject to the Plan
                   -----------------------------------

              Except as provided in subparagraphs 6(h) and 6(i), the number

         of shares that may be issued or transferred pursuant to the

         exercise of options granted under the Plan shall not exceed

         2,750,000 shares of Common Stock.  Such shares may be authorized

         and unissued shares or previously issued shares acquired or to be

         acquired by the Company and held in treasury.  Any shares subject

         to an option which for any reason expires or is terminated

         unexercised as to such shares or which are used to pay for the

         exercise of an option may again be subject to an option right

         under the Plan.  If the aggregate fair market value (determined at

         the time the option is granted) of the stock with respect to which

         incentive stock options are exercisable for the first time by any

         optionee during any calendar year (under the Plan and any other

         plan of the Company or a parent or a subsidiary of the Company)

         exceeds $100,000 then the Committee may designate which options

                                      -2-
<PAGE>
 
         are non-qualified stock options and which are incentive stock

         options.

              4.   Eligibility
                   -----------

              Incentive stock options may be granted only to management and

         other key employees who are employed by the Company or a parent or

         subsidiary of the Company.  An incentive stock option may be

         granted to a director of the Company or a parent or subsidiary of

         the Company, provided that the director is also an officer or key

         employee.  Directors who are not officers or key employees may

         only be granted non-qualified stock options.

              5.   Granting of Options
                   -------------------
    
              All options pursuant to this Plan shall be granted within 10

         years from the effective date of this Plan.  The date of the grant

         of any option shall be the date on which the Committee authorizes

         the grant of such option.

              6.   Options
                   -------

              Options shall be evidenced by stock option agreements in such

         form, not inconsistent with this Plan, as the Committee shall

         approve from time to time, which agreements need not be identical

         and shall be subject to the following terms and conditions:

                   (a)  Option Price.  The purchase price under each
                        ------------              
              incentive stock option shall be not less than 100% of the
              fair market value of the Common Stock at the time the option
              is granted and not less than the par value of such Common
              Stock.  In the case of an incentive stock option granted to
              an employee owning more than 10% of the total combined voting
              power of all classes of stock of the Company or of any parent
              or subsidiary of the Company (a "10% Stockholder"), actually
              or constructively under Section 422(b)(6) and 424(d) of the
              Code, the option price shall not be less than 110% of the
              fair market value of the Common Stock subject to the option
              at the time of its grant.  The purchase price under each
              non-qualified stock option shall be specified by the
              Committee, but shall in no case be less than the par value of
              the Common Stock subject to the non-qualified stock option.
              The fair market value of the Common Stock on any date shall
              be determined in a manner consistent with the requirements of
              the Code.

                                      -3-

                   (b)  Payment of Exercise Price.  Payment of the option
                        -------------------------
              exercise price shall be made in full at the time the notice
              of exercise of the option is delivered to the Company and
              shall be in cash, bank certified or cashier's check or
              personal check (unless at the time of exercise the Option
              Committee in a particular case determines not to accept a
              personal check) for the Common Stock being purchased.
      
                        The Option Committee can determine at the time the
              option is granted for incentive stock options, or at any time
              before exercise for nonqualified stock options, that
              additional forms of payment will be permitted.  To the extent
              permitted by the Option Committee and applicable laws and
              regulations (including, but not limited to, federal tax and
              securities laws and regulations and state corporate law), an
              option may be exercised by:

                        (i)  delivery of shares of stock of the Company
                   held by an Optionee having a fair market value equal to
                   the exercise price, such fair market value to be
                   determined in good faith by the Option Committee;
                   provided, however, that payment in stock held by an
                   Optionee subject to Section 16(b) of the Securities
                   Exchange Act of 1934 (the "Exchange Act") shall not be
                   made unless the stock shall have been owned by the
                   Optionee for a period of at least six months;

                       (ii)  delivery of a properly executed exercise
                   notice, together with irrevocable instructions to a
                   broker, all in accordance with the regulations of the
                   Federal Reserve Board, to promptly deliver to the
                   Company the amount of sale or loan proceeds to pay the
                   exercise price and any federal, state or local
                   withholding tax obligations that may arise in connection
                   with the exercise; provided, that the Option Committee,
                   in its sole discretion, may at any time determine that
                   this subparagraph (b), to the extent the instructions to
                   the broker call for an immediate sale of the shares,
                   shall not be applicable to any Optionee who is subject
                   to Section 16(b) of the Exchange Act, or is not an
                   employee at the time of exercise;

                      (iii)  delivery of a properly executed exercise
                   notice together with instructions to the Company to
                   withhold from the shares that would otherwise be issued
                   upon exercise that number of shares having a fair market
                   value equal to the option exercise price.

                   The Company or any related corporation shall have the
              right to retain and withhold from any payment of cash or
              Common Stock under the Plan the amount of taxes required by
              any government to be withheld or otherwise deducted and paid
              with respect to such payment.  At its discretion, the Company
              may require an Optionee receiving shares of Common Stock to
             
                                      -4-
<PAGE>
 
              reimburse the Company for any such taxes required to be
              withheld by the Company and withhold any distribution in
              whole or in part until the Company is so reimbursed.  In lieu
              thereof, the Company shall have the right to withhold from
              any other cash amounts due or to become due from the Company
              to the Optionee an amount equal to such taxes or retain and
              withhold a number of shares having a market value not less
              than the amount of such taxes required to be withheld by the
              Company to reimburse the Company for any such taxes and
              cancel (in whole or in part) any such shares so withheld.  If
              required by Section 16(b) of the Exchange Act, the election
              to pay withholding taxes by delivery of shares held by any
              person who at the time of exercise is subject to Section
              16(b) of the Exchange Act, shall be made either six months
              prior to the date the option exercise becomes taxable or at
              such other times as the Company may determine as necessary to
              comply with Section 16(b) of the Exchange Act.

                   (c)  Waiting Period.  The waiting period and time for
                        --------------
              exercising an option shall be prescribed by the Committee in
              each particular case; provided, however, that no incentive
              stock option may be exercised after 10 years from the date it
              is granted.  In the case of an incentive stock option granted
              to a 10% Stockholder, such option, by its terms, shall be
              exercisable only within five years from the date of grant.

                   (d)  No Rights as a Stockholder.  A recipient of options
                        --------------------------              
              shall have no rights as a stockholder with respect to any
              shares issuable or transferable upon exercise thereof until
              the date a stock certificate is issued to him for such
              shares.  Except as otherwise expressly provided in the Plan,
              no adjustment shall be made for dividends or other rights for
              which the record date is prior to the date such stock
              certificate is issued.

                   (e)  Non-Assignability of Options.  No option shall be
                        ----------------------------               
              assignable or transferable by the recipient, except by will
              or by the laws of descent and distribution.  During the
              lifetime of a recipient, options shall be exercisable only by
              him, his guardian or legal representative.

                   (f)  Effect of Termination of Employment or Death.  No
                        --------------------------------------------           
              option granted to an employee shall be exercisable after
              termination of employment with the Company or any parent or
              subsidiary of the Company unless such termination of
              employment occurs by reason of retirement with the consent of
              the Company or death.  In the event of the retirement of a
              recipient of options with the consent of the Company, the
              options or unexercised portions thereof which were otherwise
              exercisable on the date of retirement shall expire unless
              exercised within a period of three months after the date of
              retirement; provided, however, that if such retirement is due
              to disability within the meaning of Section 422(c)(6) and
              22(e)(3) of the Code, then the aforementioned right to
              exercise such option shall exist for one year following the
              date of retirement.  In the event of the death of a recipient
              of options while an employee of the Company or any parent or
              subsidiary of the Company or in the event of the death of the
             
                                        -5-

              recipient within the three-month (or one year) period
              following termination of employment by reason of retirement
              with the consent of the Company, the options which were
              otherwise exercisable on the date of termination of
              employment shall be exercisable by his personal
              representatives, heirs, or legatees at any time prior to the
              expiration of one year from the date of his death.  In no
              event, however, shall an incentive stock option be
              exercisable after 10 years from the date it is granted.  In
              the event that a recipient ceases to be an employee of the
              Company or of any parent or subsidiary of the Company for any
              reason, including death or retirement, prior to the lapse of
              any applicable waiting period, his option shall terminate and
              be null and void.  The Committee may, if it determines that
              to do so would be in the Company's best interests, provide in
              a specific case or cases for the exercise of options which
              would otherwise terminate upon termination of employment with
              the Company for any reason, upon such terms and conditions as
              the Committee determines to be appropriate.  Option rights
              shall not be affected by any change of employment as long as
              the recipient continues to be employed by either the Company
              or a parent or subsidiary of the Company.  Nothing in the
              Plan or in any option agreement shall confer any right to
              continue in the employ of the Company or any parent or
              subsidiary of the Company or interfere in any way with the
              right of the Company or any parent or subsidiary of the
              Company to terminate the employment of a recipient at any
              time.

                   (g)  Leave of Absence.  In the case of a recipient on an
                        ----------------   
              approved leave of absence, the Committee may, if it
              determines that to do so would be in the best interests of
              the Company, provide in a specific case for continuation of
              options during such leave of absence, such continuation to be
              on such terms and conditions as the Committee determines to
              be appropriate, except that in no event shall an incentive
              stock option be exercisable after 10 years from the date it
              is granted.

                   (h)  Recapitalization.  In the event that dividends
                        ----------------     
              payable in Common Stock during any fiscal year of the Company
              exceed in the aggregate 5% of the Common Stock issued and
              outstanding at the beginning of the year, or in the event
              there is during any fiscal year of the Company one or more
              splits, subdivisions, or combinations of shares of Common
              Stock resulting in an increase or decrease by more than 5% of
              the shares outstanding at the beginning of the year, the
              number of shares available under the Plan shall be increased
              or decreased proportionately, as the case may be, and the
              number of shares deliverable upon the exercise without change
              in the aggregate purchase price.  Common Stock dividends,
              splits, subdivisions, or combinations during any fiscal year
              which do not exceed in the aggregate 5% of the Common Stock
              issued and outstanding at the beginning of such year shall be
              ignored for purposes of the Plan.  All adjustments shall be
              made as of the day such action necessitating such adjustment
              becomes effective.

                   (i)  Sale or Reorganization.  In case the Company is
                        ---------------------- 
              merged or consolidated with another corporation, or in case
              the property or stock of the Company is acquired by another
              corporation, or in case of a separation, reorganization, or
              liquidation of the Company, the Board of Directors of the
              Company, or the board of directors of the corporation
              assuming the obligations of the Company hereunder, shall
              either (i) make appropriate provisions for the protection of
              any outstanding options by the substitution on an equitable
              basis of appropriate stock of the Company, or appropriate
              stock of the merged, consolidated, or otherwise reorganized
              corporation, provided only that such substitution of options
              shall comply with the requirements of Section 424 of the
              Code, or (ii) give written notice to optionees that their
              options, which will become immediately exercisable
              notwithstanding any waiting period otherwise prescribed by
              the Committee, must be exercised within 30 days of the date
              of such notice or they will be terminated.

                   (j)  General Restrictions.  Each option granted under
                        --------------------             
              the Plan shall be subject to the requirement that, if at any
              time the Board of Directors or the Committee shall determine,
              in its discretion, that the listing, registration, or
              qualification of the shares issuable or transferable upon
              exercise thereof upon any securities exchange or under any
              state or federal law, or the consent or approval of any
              governmental regulatory body is necessary or desirable in
              accordance with any state or federal law, or the consent or
              approval of any governmental regulatory body is necessary or
              desirable as a condition of, or in connection with, the
              granting of such option or the issue, transfer, or purchase
              of shares thereunder, such option may not be exercised in
              whole or in part unless such listing, registration,
              qualification, consent, or approval shall have been effected
              or obtained free of any conditions not acceptable to the
              Board of Directors.

              The Company shall not be obligated to sell or issue any

         shares of Common Stock in any manner in contravention of the

         Securities Act of 1933, as amended, or any state securities law.

         The Board of Directors or the Committee may, in connection with

         the granting of each option, require the individual to whom the

         option is to be granted to enter into an agreement with the

         Company stating that as a condition precedent to each exercise of

         the option, in whole or in part, he shall, if then required by the

         Company, hold the Common Stock received upon such exercise for a

         period prescribed by the Committee not to exceed two years and

         represent to the Company in writing that such exercise is for

         investment only and not with a view to distribution, and also


                                      -7-
<PAGE>
 
         setting forth such other terms and conditions as the Board of

         Directors or the Committee may prescribe.  Such agreements may

         also, in the discretion of the Board of Directors or the

         Committee, contain provisions requiring the forfeiture of Common

         Stock received upon exercise of any option in the event of the

         termination of employment or association (unless caused by death),

         as the case may be, of the optionee with the Company during a

         period not to exceed two years after the exercise of the option.

         Upon any forfeiture of Common Stock pursuant to an agreement

         authorized by the preceding sentence, the Company shall return the

         purchase price for such Common Stock to the optionee, without

         interest thereon or deduction therefrom.

              7.   Termination and Amendment of the Plan
                   -------------------------------------    
   
              The Board of Directors shall have the right to amend,

         suspend, or terminate the Plan at any time; provided, however,

         that no such action shall affect or in any way impair the rights

         of a recipient under any option right theretofore granted under

         the Plan; and, provided, further, that unless first duly approved

         by the stockholders of the Company entitled to vote thereon at a

         meeting (which may be the annual meeting) duly called and held for

         such purpose, except as provided in subparagraphs 6(h) and 6(i),

         or by a consent of stockholders, no amendment or change shall be

         made in the Plan:  (a) increasing the total number of shares which

         may be issued or transferred under the Plan; (b) changing the

         purchase price hereinbefore specified for the shares subject to

         options; (c) extending the period during which options may be

         granted or exercised under the Plan; or (d) changing the

         designation of persons eligible to receive options under the Plan.

              8.   Restriction on Sale of Shares
                   -----------------------------  

              Without the written consent of the Company, no stock acquired

         by an optionee upon exercise of an incentive stock option granted

         hereunder may be disposed of by the optionee within two years from

         the date such incentive stock option was granted, nor within one


                                       -8-
<PAGE>
 
         year after the transfer of such stock to the optionee; provided,

         however, that a transfer to a trustee, receiver, or other

         fiduciary in any insolvency proceeding, as described in Section

         422(c)(3) of the Code, shall not be deemed to be such a

         disposition.  The optionee shall make appropriate arrangements

         with the Company for any taxes which the Company is obligated to

         collect in connection with any such disposition, including any

         Federal, state, or local withholding taxes.

              9.   Effective Date of the Plan
                   --------------------------

                                W I T N E S S E T H:
                                - - - - - - - - - -

                   WHEREAS, Cambridge Heart is engaged in the development
         of systems performing exercise stress test or measuring electrical
         alternans; and

                   WHEREAS, Cambridge Heart has no distribution facilities,
         places of business or employees in Europe and desires to arrange
         for the distribution of its products in the area specified as the
         Territory on Attachment A (the "Territory"); and

                   WHEREAS, Distributor desires to become the exclusive
         distributor in Europe of Cambridge Heart's exercise stress test
         system;

                   NOW THEREFORE, in consideration of the mutual promises,
         covenants and conditions hereinafter contained, it is hereby
         agreed as follows:

         1.     Appointment and Territory.  
                -------------------------

         1.1    Distributor is appointed exclusive and sole distributor in
         the Territory for the Cambridge Heart Products (the "Products")
         listed in Attachment A and their successors and extensions,
         subject to the terms and conditions set forth in this agreement.
         Cambridge Heart shall have the right subject to the prior written
         approval of the distributor to appoint one or more OEMs in the
         Territory to sell a private label version of the Product,
         incorporated in a system or product consisting of a substantial
         amount of other hardware and/or software which such OEM
         manufactures, integrates or develops, and which will not include
         electrical alternans calculation.  The distributor shall not
         unreasonably withhold such approval.

         1.2    Kontron does not become an agent of Cambridge Heart by
         virtue of this Agreement but rather shall purchase and sell in its
         own name and for its own account, without being entitled to act in
<PAGE>
 
         the name of Cambridge Heart or to obligate Cambridge Heart in any
         form towards any third party.

         1.3    Kontron shall safeguard the interests of Cambridge Heart
         with the due diligence of a responsible businessman and keep
         Cambridge Heart informed as to its activities.  

         1.4    Kontron is entitled to appoint distributors, sub-
         distributors, or directly/indirectly employed agents for the sale
         of Cambridge Heart products in the Territory.  Lists of such
         agents shall be at Cambridge Heart's disposal for consultation at
         any time.  Such distributors, sub-distributors, or
         directly/indirectly employed agents shall be subject to the terms
         of this Agreement.

         1.5    This Agreement and the rights, duties and obligations
         hereunder, may not be assigned or delegated by any party without
         the prior written consent of the party.  Except that Kontron may
         specifically assign the Agreement to any of its sister companies
         listed in Attachment B, provided, that no such assignment shall
         relieve Kontron of any responsibility or liability hereunder
         (including its responsibility to coordinate its distribution
         activities from a single point of contact).  Notwithstanding the
         foregoing, Cambridge Heart may assign its rights or delegate its
         duties hereunder to any affiliated person or entity which
         controls, is controlled by, or is under common control with,
         Cambridge Heart or to any successor to its business.

         2.     Term and Termination
                -------------------- 

         2.1    Term:  This agreement commences on the date of the
                ----
         execution of this agreement and continues until December 31, 1997,
         unless sooner terminated in accordance with the provisions of the
         Paragraphs below.  This agreement shall be automatically renewed
         for successive two-year periods unless terminated in accordance
         with the provisions for termination outlined in the Agreement.   

         2.2    The parties agree to negotiate in good faith new Sales
         Minima and Marketing Plans for each renewal term commencing no
         later than ninety (90) days before the end of the initial term or
         two year renewal term.  The Sales Minima for subsequent periods
         shall not be less than the greater of the actual sales of Products
         in the Territory and the Sales Minima for the previous 12 month
         periods ending with the start of negotiations or with the end of
         the previous term.

         If either party believes at the end of such 90-day negotiation
         period that the other is not negotiating concerning renewal terms
         in good faith, such party may require that the renewal terms be
         finally settled by arbitration in Boston, Massachusetts, under the


                                         -2-
<PAGE>
 
         Rules of Conciliation and Arbitration of the International Chamber
         of Commerce by three arbitrators appointed in accordance with such
         Rules; The arbitrator shall decide between the final proposal of
         Distributor and of Cambridge Heart made prior to the end of the
         ninety-day period.

         2.3    Ordinary termination will require 24 months written notice
         by either party.  Such notice cannot be given before December,
         1996.  In the event of such a notice of termination by Cambridge
         Heart, Cambridge Heart shall have the right to render the
         Distributor's exclusive distribution rights non-exclusive by at
         least 90 days notice in writing but not effective prior to the
         expiration of the first 12 months of the 24 months ordinary
         termination notice period.  In the event of such a notice of
         termination by Distributor, Cambridge Heart may terminate this
         agreement at any time upon thirty (30) days written notice.

         During the period of the 24 months termination phase in which the
         Distributor's rights remain exclusive, Distributor must continue
         to achieve the Sales Minima and must sell not less in any calendar
         quarter than the amount sold in the equivalent quarter in the year
         before termination.

         During the period of the 24 month termination phase in which the
         Distributor rights may be non-exclusive, the distributor will
         continue to use its best efforts to continue to promote, advertise
         and market the products of Cambridge Heart, but will not be
         required to meet any sales Minimum or Marketing Plans and will
         receive terms of trade as favorable as those offered to any other
         distributor operating in the Territory.

         2.4    Cambridge Heart shall also have the right, by at least six
         (6) months' written notice to Distributor given within 6 months of
         the event, to terminate the agreement (the ability to so terminate
         being a material inducement to Cambridge Heart to the appointment
         of and grant of a license to Distributor hereunder), if
         Distributor has failed to achieve the Sales Minima defined in
         Appendix C.

         In the event that Distributor's failure to reach an agreed Sales
         Minimum results from any of the following specified conditions,
         Distributor shall be entitled to delay its compliance with sales
         minimas adversely affected by such condition, by the amount of
         such delay:

                (a)     The failure of Cambridge Heart to obtain regulatory
                        approval of the Product specified in Paragraph 9.1
                        hereof by January 31, 1995;

                (b)     The failure of Cambridge Heart to ship products

                        period.  

         2.5    This agreement may be terminated by mutual consent of the
         parties hereto and may also be terminated by written notice to any
         party hereto as follows:

                        party.

                (b)     In the case of insolvency or bankruptcy of either
                        party.

                        in whole or in part or shall sell or assign all or
                        any of its shares to any competitor.

                (d)     If such party shall fail to perform or comply with
                        any material terms, provisions or conditions of
                        this agreement to be performed or complied with or
                        by it and shall fail to remedy such default or
                        failure, or, in the event that such remedy is not
                        entirety within its control, shall have failed to
                        take all reasonable steps within its control to
                        affect such remedy, within thirty (30) days after
                        receipt of written notice thereof.

         2.6    During any 24 month ordinary termination period Cambridge
         Heart may terminate without any further notice or payment by the
         payment of:

                (a)     for each remaining month of the exclusive portion

         Cambridge Heart will use its best efforts to ship orders within
         Distributors most recent quarterly forecast within 45 days after
         receipt of the Purchase Order and other required ordering
         documentation.

         4.5    Payment for shipments through December 31, 1997 shall be
         45 days from the date of shipment; payment for shipments
         thereafter shall be due 60 days from the date of shipment.

         5.     Forecasting
                -----------

         5.1    On or before the first day of each calendar quarter during
         the term of this agreement, Distributor will deliver to Cambridge
         Heart a written forecast of the number and type of products
         Distributor intends to order during each of the next six
         successive calendar months.  

         6.     Software
                -------- 

         6.1    Cambridge Heart grants to Distributor a nontransferable
         limited license to (i) use and display the object code version of
         the Software in promoting and servicing Products in accordance
         with this agreement, and (ii) copy and grant sublicenses of the
         run time version of the Software included in the Product for use
         solely with and as part of the Product for which license fees are
         paid to Cambridge Heart in accordance with this agreement.  For
         purposes hereof, "Software" shall mean the programs, routines,
         subroutines, algorithms, translations, compilers and operating
         systems which Cambridge Heart has developed or has the right to
         sublicense for general commercial use with the Product.

         6.2    In order to constitute a valid license of the Software
         object code, prior to delivery of Software to each end user,
         Distributor shall have each end user execute a Software License
         Agreement with Distributor acting on behalf of and assigning its
         rights to Cambridge Heart in a form approved in advance by
         Cambridge Heart (the "Software License Agreement"). Upon execution
         of the Software License Agreement by the end user, Distributor
         shall forward an original, executed copy of such license agreement
         to Cambridge Heart.  Distributor shall use reasonable efforts to
         ensure that all end users comply with the terms of the Software
         License Agreement at all times and shall promptly notify Cambridge
         Heart of any breaches of such agreements when such breaches become
         known to Distributor.

         The parties recognize that it may be difficult to obtain
         signatures from certain types of customers or in certain
         jurisdictions, and in the event that Kontron encounters such


                                         -7-
<PAGE>
 
         difficulties in general, the parties will negotiate in good faith
         an alternative to this requirement consistent with Kontron's
         obligation to protect Cambridge Heart's software with the same
         diligence with which it protects its own.

         6.3    Distributor agrees to the terms and provisions of the
         Software License Agreement attached as Appendix D with respect to
         the Software as if set forth in full herein, except that
         Distributor may transfer copies of the Software in object code
         form to valid licensees of Cambridge Heart in accordance with the
         terms of this agreement.  Title to and ownership of the Software
         shall at all times remain the exclusive property of Cambridge
         Heart or of Cambridge Heart's licensors, as appropriate.
         Distributor shall have no access to the source code for the
         Software.  Distributor shall not make any modification to or
         enhancement of the Software without the prior written consent of
         Cambridge Heart.

         6.4    Distributor shall maintain such books and records as are
         necessary to properly calculate and verify the amount of license
         fees or other amounts to be paid pursuant to this agreement.
         Distributor will maintain and supply to Cambridge Heart at its
         reasonable request a complete and accurate listing of the
         disposition of all systems shipped by Cambridge Heart and the
         software options installed upon each.  Cambridge Heart shall have
         the right from time to time to inspect all of the accounting,
         sales and customer service books and records of Distributor as
         they pertain to Products to ensure compliance with the terms of
         this agreement.  Any such audit may be conducted by Cambridge
         Heart staff and/or a certified public accountant or other
         representative selected by Cambridge Heart, upon reasonable notice
         and during normal business hours, in such manner as not to
         interfere with Distributor's normal business activities.  The cost
         of any such inspection shall be borne by Cambridge Heart, except
         that if any such inspection or the inspections with respect to any
         twelve-month period shall indicate a shortfall in the payment of
         royalties or other amounts of ten percent (10%) or more,
         Distributor shall bear the expense of such inspection or
         inspections.

         7.     Marketing and Promotion
                -----------------------
         7.1    Distributor agrees to use its best efforts to promote,
         advertise and market the Products and solicit orders.  Distributor
         shall install Products, train customers and provide service for
         the products, in accordance with Cambridge Heart's approved
         procedures, and provide Cambridge Heart with current and timely
         information regarding market conditions in the Territory in a
         professional manner. Distributor also agrees to accomplish the
         marketing activities specified in the Marketing Plan attached as


                                         -8-
<PAGE>
 
         Appendix B.

         7.2    It is understood and agreed that all patents and patent
         rights, trademarks, copyrights, tradenames and other property
         rights in and with respect to the Products are and will remain
         exclusively the property of the Cambridge Heart and Distributor
         shall not be entitled to register or attempt to register any such
         mark, name or right in any jurisdiction in the name of
         Distributor.  Solely for the purpose of marketing Products,
         Distributor may, during the term of this agreement, indicate that
         it is an authorized distributor for Products and may advertise the
         same under the trademark for the product of Cambridge Heart.  All
         Distributor advertising using any tradename, trademark, service
         marks, or logos of Cambridge Heart shall appropriately credit
         Cambridge Heart.

         7.3    If Distributor advertises the sale and service of Products,
         Distributor shall not use any advertising which tends to mislead
         or deceive the public.  Distributor may use printed advertising
         and promotional materials furnished by Cambridge Heart or may use
         its own materials.  Copies of all such materials will be made
         available to Cambridge Heart upon reasonable request; Distributor
         is encouraged to make them available in advance for a review of
         accuracy.  Cambridge Heart agrees to provide reasonable quantities
         of its own sales literature, training and promotional materials in
         English free of charge.  

         7.4    Demo Units.  Distributor agrees to purchase and maintain,
                ----------
         or cause its subdistributors to purchase and maintain, in its
         possession and in working order during the term of this agreement
         a minimum of one fully configured demo system in each Country of
         the Territory. The schedule for such purchases is described in
         Appendix B.  Each subdistributor of Distributor in the Primary and
         Secondary Distributor Territories may sell and replace one demo
         unit per year, each must be held for one year before being sold.

         8.     New Products
                ------------
         Cambridge Heart intends to develop an imaging system for stress
         test to be added to the CH 2000 line which, if development is
         successful, will be offered to Distributor for distribution or
         sale.  Distributor agrees to develop and execute a marketing plan
         for such system comparable in scope to the Marketing Plan for the
         CH 2000.  The parties agree to negotiate the details of such
         Marketing Plans, the Sales Minimas and Prices for such system in
         good faith.  In the event that the parties cannot agree on such
         matters within ninety (90) days after the first notification by
         Cambridge Heart to Distributor of the terms of distribution for
         such new system, then Cambridge Heart may offer the new imaging
         system to another distributor at terms more favorable to Cambridge


                                         -9-
<PAGE>
 
         Heart in some material way to those last offered by Distributor or
         require Distributor to distribute the new imaging system with an
         automatic *** increase in the existing Sales Minimas to reflect
         the sales of the new system.  

         In the event that Cambridge Heart develops other future systems
         for exercise stress test, targeted at a different market segment
         or price point, which are suitable for distribution through direct
         sales, Cambridge Heart will first negotiate with Distributor, for
         ninety (90) days, for the distribution of such systems in the
         Territory.

         9.     Regulatory Compliance
                ---------------------
         9.1    Cambridge Heart will obtain CE mark approval for the
         product prior to January 31, 1995 and name Distributor as its
         European Representative.  Distributor agrees to be named as
         Cambridge Heart's European Representative for regulatory purposes
         for European countries outside of the Territory.  Cambridge Heart
         will bear all the costs relating to the obtainment of such
         regulatory approvals.  

         9.2    Distributor will at all times fully comply with all
         regulations of the United States Food and Drug Administration and
         applicable European authorities with respect to the monitoring of
         complaints and maintenance of repair and other records.
         Distributor shall forward such documents to Cambridge Heart at
         such frequency as shall be reasonably requested by Cambridge
         Heart, and shall cooperate with Cambridge heart in all complaint
         measures deemed by Cambridge heart to be necessary or appropriate,
         including any voluntary recall of Products.  Cambridge Heart will
         cooperate fully with Kontron's CAR/F3 complaint handling
         procedure.  

         9.3    Distributor agrees that neither it nor its customers intend
         to or will, directly or indirectly, export the Products or
         transmit the Software or related documentation and technical data
         to any country if such export or transmission is prohibited by any
         U.S. regulation or statute without the prior written consent of
         the bureau of Export Administration of the U.S. Department of
         Commerce or such other government entity as may have jurisdiction
         over such export or transmission.  Cambridge Heart agrees to
         notify Distributor of any changes to the list of countries to
         which such export is prohibited.

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

<PAGE>
 
         faithfully and to the best of its ability, in a professional and
         responsible manner, at a level and with response times, rates and
         other attributes consistent with the highest performance offered
         in the Territory for other stress test equipment, by competitors
         or others.  Distributor shall develop a written Service Plan by no
         later than March 31, 1996 for discussion with and approval by
         Cambridge Heart.  Distributor shall purchase and maintain a spare
         parts inventory and provide customer training in accordance with
         the Service Plan.  Distributor will also ensure that all
         subdistributors are formally trained in service of the product and
         maintain in their possession adequate spare parts in accordance
         with such Service Plan.  

         11.    Limited Warranty; Disclaimers
                -----------------------------

         11.1   Cambridge Heart warrants for a period of fifteen (15)
         months from shipment by Cambridge Heart to Distributor, or twelve

         Distributor's expense and to provide a 12-month parts and labor
         warranty to its customers of the Products.

         INDIRECT OR CONSEQUENTIAL DAMAGES OF THE OTHER PARTY OR ANYONE
         CLAIMING THROUGH OR ON BEHALF OF THE OTHER PARTY, INCLUDING LOSS
         OF USE, REVENUE, OR PROFITS, IN CONNECTION WITH OR ARISING OUT OF
         THIS AGREEMENT OR ANY BREACH OF THIS AGREEMENT BY CAMBRIDGE HEART
         OR THE EXISTENCE, FURNISHING, FUNCTIONING, OR DISTRIBUTOR'S OR ANY
         THIRD PARTY'S USE OF ANY PRODUCTS OR SERVICES PROVIDED FOR IN THIS
         AGREEMENT, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY
         OF SUCH DAMAGES.

<PAGE>
 
         11.2   Cambridge Heart's warranties set forth in Paragraph 11.1
         shall not apply in circumstances that would be excluded by its
         standard end user warranty terms, such as misuse or alteration of
         the Product or use of the Product for other than the specific
         purpose for which it is designed.

         shall be to: (i) accept, analyze and provide written response to
         any reports from Distributor of Software malfunction or error; and
         (ii) use best efforts to provide responses to correct such errors
         within a commercially feasible time scale when they reflect
         significant deviations from Cambridge Heart's design
         specifications for the current release of the Software.  

         12.    Confidentiality
                ---------------

         12.1   Distributor agrees to keep confidential any and all trade
         information, proprietary information (including, without

         Heart acquired pursuant to this agreement except as authorized in
         writing by Cambridge Heart.

         13.    Covenant; Indemnity
                -------------------

         13.1   Distributor does not, and shall not during the term of this
         agreement (including any two-year period following termination of
         the contract initiated by the distributor) directly or indirectly,
         manufacture, develop, distribute or sell in whole or in part, a
         system for performing an exercise stress test or measuring
         electrical alternans, other than a Product of Cambridge Heart,
         without the express written permission of Cambridge Heart.

         The relationship between Kontron Instruments and Pulse Biomedical

         test type software is specifically excluded from this Covenant.

         13.2   Cambridge Heart shall keep Kontron indemnified and harmless
         against any liability or damages caused by any claim of a third
         party relating to the manufacture of a Product furnished to
         Kontron by Cambridge Heart which did not meet the specifications
         in effect at the time of confirmation of the purchase order, or
         from the negligence or other wrongdoing of Cambridge Heart or any
         employee or agent of Cambridge Heart (other than Kontron).
         Kontron shall keep Cambridge Heart indemnified and harmless
         against any liability or damages caused by packaging by Kontron,
         registration, distribution, promotion of the products for use or

<PAGE>
 
         use of the Products outside of their specifications or against
         their specific warnings, precautions or contraindications, or from
         the negligence, failure to comply with instructions regarding use
         of the Product, or other wrongdoing of Kontron or any employee or
         agent of Kontron.

         In the event that other damages which arise out of transactions
         related to this agreement are alleged against either Kontron or
         Cambridge Heart or both, then Kontron and Cambridge Heart shall
         cooperate to defend against and defeat such allegations, but if
         such damages should be found and allowed against either Kontron or
         Cambridge Heart or both, then Kontron and Cambridge Heart shall
         indemnify each other against the same, such that the parties shall
         bear the damages and the costs of defense equally.

         business day following the date so mailed.

         14.2   The headings of the Paragraphs of this agreement are for
         convenience only and will not be of any effect in construing the
         meaning of the Sections.  This agreement may be executed in

         of which taken together shall constitute but one and the same
         instrument.

         14.3   This agreement may not be modified, changed or
         supplemented, nor may any obligations hereunder be waived or

         15.    Choice of Law, Arbitration and Force Majeure
                --------------------------------------------

         15.1   This Agreement including the arbitration clause, shall be
         interpreted and construed in accordance with the laws of England,
         it being expressly understood that the United Nations
         International Conventions on the Sale of goods shall not apply.

         15.2   Any differences or disputes arising from this Agreement or
         from agreements regarding its performance, shall be settled by an
         amicable effort on the part of both parties to the Agreement by
         their respective chief executive officers or their delegates.  An
         attempt to arrive at a settlement shall be deemed to have failed
         as soon as one of the parties to this agreement notifies the other
         party in writing.

         15.3   If an attempt at settlement has failed, disputes, including
         those relating to Paragraph 2 hereof, shall be finally settled in
         the English language under the rules of the Conciliation and
         Arbitration of the International Chamber of Commerce by three
         arbitrators appointed in accordance with the Rules, the place of
         arbitration being Boston, Massachusetts; Notwithstanding the
         foregoing arbitration agreement, the parties shall be entitled to
         apply to any court of competent jurisdiction for a prearbital
         injunction, prearbital attachment or other order in aid of
         arbitration proceedings and enforcement of an arbitration award.

         15.4   The arbitral decision shall be substantiated in writing.
         The arbitral tribunal shall decide on the matter of costs of the
         arbitration.

         15.5   Neither party shall be liable for failure to perform
         obligations under this Agreement if the failure results from the
         force majeure, such as fire, explosion, acts of ware, or
         hostilities of any nature, accident, refusal of license, or other
         governmental act (including regulatory approvals and export/import
         licenses), industrial dispute, or anything manifestly beyond the
         parties' control.  

         This Agreement consists of 21 pages, including two attachments,
         five appendices and one amendment.  

                   IN WITNESS WHEREOF, the parties hereto have duly

                          CH-2000 Cardiac Diagnostic System

              This is a legal agreement between you (either individual or
         entity), the end user, and Cambridge Heart, Inc. ("CHI").  

                          CAMBRIDGE HEART LICENSE AGREEMENT

         Grant of License.  Upon acceptance by CHI, CHI grants to you the
         ----------------
         right to use one copy of the CHI software program identified above
         (the "Software") on the single computer on which the Software is
         initially installed by CHI (the "Dedicated Computer"), in the
         country indicated across from your signature below.

         Ownership; Copyright.  As the licensee, you own the physical media
         --------------------
         on which the Software is originally or subsequently recorded, but
         CHI and its licensors (if any) retain title and ownership of the
         Software recorded on the original disk or other media and all
         subsequent copies of the Software, regardless of the form or media
         in or on which the original and other copies may exist.  This
         license is not a sale of the original Software or any copy
         thereof.  The Software and the accompanying written materials are
         patented and copyrighted and are protected by United States patent
         and copyright laws and international treaty provisions, and
         further, contain trade secret and proprietary information.
         Therefore, you must treat the Software like any other patented and
         copyrighted material (e.g., a book or musical recording) and trade
         secret information.  Subject to these restrictions, you may either
         (a) make one copy of the Software solely for backup purposes in
         support of your permitted use of the Software on the Dedicated
         Computer, or (b) transfer the Software to a single hard disk on
         the Dedicated Computer provided you keep the original solely for
         backup purposes.  (Programs, however, may include mechanisms to
         limit or inhibit copying, and they are marked "copy protected";
         programs on CD-ROM will not be copyable.)  The patent, copyright
         and other notices must be reproduced on the backup copy.  You may
         not copy the written materials accompanying the Software.

         ------------------
         you may transfer your rights under this Agreement on a permanent
         basis in conjunction with your transfer of the Dedicated Computer,
         provided at the same time you transfer the Software (including all
         copies, whether in printed, machine readable form or otherwise,
         and all accompanying written materials) and Dedicated Computer you
         retain no copies, the recipient agrees in writing to accept the
         terms of this Agreement and such writing is delivered to and
         accepted by CHI.  Any such transfer, or any transfer of possession
         of any Software in whole or in part to another party shall


                                         -22-

         update, any transfer must include the update and all prior
         versions.  YOU MAY NOT DISTRIBUTE COPIES OF THE SOFTWARE OR THE
         ACCOMPANYING WRITTEN MATERIALS TO OTHERS.  YOU MAY NOT MODIFY,
         ADAPT, TRANSLATE, REVERSE ENGINEER, DECOMPILE, DISASSEMBLE, OR
         CREATE DERIVATIVE WORKS BASED ON THE SOFTWARE OR THE WRITTEN
         MATERIALS.  

         Dual Media Software.  If the Software package contains both
         -------------------
         diskettes and CD-ROM, then you may use only the media appropriate
         for your single Dedicated Computer.  You may not use the other
         media on another computer or computer network, or loan, rent,
         lease or transfer it to another user except as part of a transfer
         or other use as expressly permitted by this Agreement.

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

         Software will perform substantially in accordance with the
         accompanying written materials under normal use and serve for a
         period of one (1) year.  This limited warranty shall not apply to

             AMENDMENT 1:  KONTRON'S SALE OF ESAOTE STRESS TEST SYSTEMS



         16.  Kontron hereby requests and Cambridge Heart hereby gives its
         permission under paragraph 13.1 of the Exclusive Distributorship
         Agreement for Kontron to have the right to sell Esaote's Stress
         Test Systems, as part of a distribution agreement for other Esaote
         Products, only in the countries of France and Spain, subject to
         the terms and restrictions described herein.  Kontron will be
         assumed to be selling such systems in these countries until it
         notifies Cambridge Heart in writing of its discontinuation of such
         sales.

         17.  Kontron commits that its agreement with Esaote does not and
         will not include unit or revenue sales targets or minima
         specifically for Esaote's Stress Test Systems; revenue minima for
         all of Esaote's products, however, are acceptable.

         18.  For any year or part in which Kontron is selling (as
         described above) Esaote's Stress Test Systems in any country it
         must meet the specific country Sales Minima for that country for
         that year.  The country Sales Minima is equal to *** of that
         country's Sales Target in Appendix C of the Agreement.  If Kontron
         fails to meet the Sales Minima in any such country then Cambridge
         Heart shall have the right to terminate Kontron's distribution
         rights in that country on six months notice.

         19.  If Cambridge Heart chooses to terminate the distribution
         rights of Kontron in any country in this manner, the ordinary
         termination period for the Exclusive Distributorship Agreement
         shall be reduced to 12 months and the maximum discount allowable
         in the remaining countries shall become ***.

         terminated earlier pursuant to paragraph 17 hereof.  The parties
         shall negotiate in good faith the terms (including Prices,
         Marketing Plans and Sales Minimums) for successive one year
         renewal periods starting one hundred and twenty (120) days before
         the end of each term.

              3.   Sales Minimums and Sales Targets.  (a)  In consideration
                   -------------------------------- 
         of this grant of exclusivity, FD shall purchase no less than the
         Sales Minimums defined in Appendix A and to use its best efforts
         to purchase the Sales Targets also described in Appendix A.

                   (b)  Notwithstanding Paragraph 3.(a) above, if FD's
         failure to reach an agreed Sales Minimum results from any of the
         following specified conditions, FD shall be entitled to suspend
         its obligation to make purchases to meet such Sales Minimum as a
         result thereof, and that if such period shall extend beyond six
         months, then either party may terminate this Agreement by written
         notice to the other:

                        (i)  Demo Units or Products supplied by CHI shall
         fail to conform to the Specifications described in Appendix C (the
         "Specifications") and CHI shall fail to remedy such nonconformance
         within sixty (60) days after receipt of written notice thereof
         from FD, which notice from FD must be within thirty (30) days
         after receipt of such goods from CHI; and

                        (ii)  CHI shall fail to comply with its obligations

                        (iii)  CHI shall fail to provide to FD technical
         support as required by this Agreement, which failure materially
         and adversely affects the ability of FD to maintain and repair
         Products, and CHI shall fail to remedy such support within sixty
         (60) days after receipt of written notice thereof from FD; and

                        (iv)  CHI shall fail to comply with the delivery
         terms provided for under Paragraph 8 hereof.

                   (c)  FD shall not be required to meet quarterly Sales
         Minimums in the first contract year in Appendix A until FD shall
         have received the first six (6) Demo Units meeting the
         Specifications.  Should CHI be delayed in shipping such Demo
         Units, the annual Sales Minimums shall be reduced by one-twelfth
         (1/12) for each month of such delay.

              4.   Prices, Terms, Discounts.  All purchases by FD shall be

         1996.  CHI shall ship the Demo Units within one (1) month from the
         receipt of the approval from MOH.  FD shall maintain in its
         possession and in working order no less than nine (9) Demo Units.
         FD may sell and replace any Demo Units.  FD shall hold each Demo
         Unit for at least one (1) year before sale.  The number of the
         Demo Units FD has purchased shall be counted in the Sales Minimums
         in Appendix A.

              6.   Specifications.  The Demo Units described in Paragraph 5
                   --------------
         and all subsequent systems shipped by CHI shall meet the
         Specifications including the Improvements requested by FD.  CHI
         shall upgrade the three (3) previously shipped Demo Units in FD's
         possession to meet these Specifications no later than one (1)
         month after receipt of MOH approval.  

              7.   Marketing, Distribution and Service.  (a)  FD shall

                   (c)  FD shall support and service the Products in the
         Territory and provide all personnel necessary for the repair of
         Products, including warranty service.  FD shall purchase and
         maintain in its possession adequate spare parts in amounts agreed
         by the parties.

                   (d)  FD shall use its best efforts to obtain a new
         reimbursement code for T-wave alternans at the earliest reasonable
         date.

         possibility of sudden death of patients caused by cardiologic
         diseases.

                   (b)  For other products related to stress test, CHI
         shall notify FD of their expected availability and shall first
         negotiate with FD for their distribution for a period not to
         exceed ninety (90) days.

              10.  Regulatory Compliance.  (a)  Each party shall at all
                   --------------------- 
         times comply with all regulations of the United States Food and

         authorities in the Territory.  Each party shall cooperate with the
         other in meeting the requirements of FDA and MOH including all
         monitoring, compliant and repair measures deemed to be necessary
         or appropriate, including any voluntary or involuntary recall of
         the Products.

                   (b)  FD shall be responsible, with CHI's support, for
         obtaining and maintaining MOH approval for the Products.  FD shall

              11.  Documentation.  CHI shall supply an English language
                   -------------
         operators manual to FD.  FD shall develop a Japanese language
         version.  FD may use printed advertising and promotional materials
         furnished by CHI or may use its own materials.  CHI shall provide
         reasonable quantities of sales literature, training and
         promotional materials to FD and to provide photographs used in
         CHI's promotional materials for use by FD in creating its own
         materials.  Each party shall provide the other, in a timely
         manner, copies of all materials used for promotion and training.

              12.  Warranty.  In accordance with the terms in Appendix E,
                   --------
         CHI shall warrant for a period of fifteen (15) months from
         shipment by CHI to FD, or twelve (12) months from shipment by FD
         to its customer, whichever is shorter ("Warranty Period"), that
         the Products shall conform to Specifications and shall be free
         from any defects and defective workmanship under normal and proper
         use in accordance with CHI's instructions, provided, however, that
         in case FD receives any claim of or relating to the above-
         mentioned CHI warranty from FD's customers during the Warranty
         Period and such claim shall be forwarded by FD to CHI within
         thirty (30) days thereafter, such claim shall be deemed made in a
         timely fashion, notwithstanding the expiration of the Warranty
         Period.

              13.  Software License.  (a)  CHI grants to FD a non-
                   ----------------
         transferable license to use the Software object code included in
         the Products for use with and as part of the Products subject to
         the terms and conditions of the end-user Software License
         Agreement attached hereto, provided that in case any term or
         condition set forth in this Agreement conflicts with Appendix F,
         this Agreement shall prevail.  CHI also grants to FD the right to
         demonstrate the Software with and as part of the Products without
         separating the Software from the Products.  FD shall have the
         right to sell licenses of the Software in object code form to
         valid licensees of CHI, provided that such Software shall remain
         part of and integrated with the Product and not in any way
         separated or transferred as a stand-alone product or used with or
         merged into any other software or product.  Title to Software and
         any and all accompanying written materials, and all intellectual
         property rights therein, shall remain the property of CHI and its
         licensors.  Consideration for the grant of the license hereunder
         shall be included in the price of the Product, and FD shall not be
         obligated to pay to CHI any other license fee, royalty or
         whatsoever for use of the Software.  For purposes hereof,
         "Software" means the programs, routines, subroutines, algorithms,
         translators, compilers and operating systems which CHI has
         developed or has the right to sublicense for general commercial
         use with the Products.

                   (b)  FD shall have each end user execute a Software
         License Agreement substantially in the form of Appendix F, as
         approved by CHI, and shall forward an original, executed copy of
         such license agreement to CHI.  FD shall use reasonable efforts to
         ensure that all end users comply with the terms of the Software
         License Agreement of Appendix F and shall promptly notify CHI of
         any breaches of such agreements known to FD.

                   (c)  CHI shall hold harmless and be responsible for or
         defend at its expense any claim or action brought against FD by
         any third party to the extent that it is based on a claim that CHI
         does not have the right to grant the license to FD set forth in
         this Paragraph 13, or the Software or any patents or copyrights
         contained therein when used within the scope of this Agreement
         infringes a patent or copyright or misappropriates a trade secret
         or other proprietary right of a third party ("Infringement").  CHI
         shall be entitled to sole control of any such action and, except
         to the extent provided below, shall pay any costs, damages and
         attorneys' fees finally awarded against FD in such action to the
         extent attributable to such claim, provided that FD notifies CHI
         promptly in writing of the claim.  FD will have the right to
         participate in the defense of any such suit, investigation or
         other proceeding through counsel of its own choosing and at its
         expense.  Should the Software become, or in either Party's opinion
         is likely to become, the subject of a claim of Infringement, CHI
         may, at its option and in satisfaction of its obligations under
         this Paragraph, procure for FD the right to continue using the
         Software or replace or modify the Software to make it non-
         infringing.  CHI may withhold further shipment of any infringing
         or allegedly infringing items, subject to the provision of one of
         the foregoing remedies.

                   CHI shall have no liability or obligation under this
         Agreement or otherwise to FD or anyone claiming through or on
         behalf of FD or for any Infringement based upon (i) any program
         loaded on a Product by anyone other than CHI or its agents;
         (ii) use of the Product in combination with a device or product
         not purchased by FD from CHI or configured by CHI as part of the
         Product, where the Product would not itself be infringing;
         (iii) use of the Product in an application or environment for
         which it was not designed or contemplated; (iv) modification of
         the Product or Software by other than CHI or without CHI's
         approval; and (v) any claim of Infringement of intellectual
         property in which FD has an interest or license.

                   The foregoing states the entire liability of CHI with
         respect to infringement or misappropriation of patent, copyright,
         trade secret or other intellectual property rights by any of the
         Products or Software, or any portion thereof, or by the


                                         -5-
<PAGE>
 
         performance, operation or use thereof, and is in lieu of (and CHI
         hereby disclaims) any other warranty, express or implied, as to
         any such infringement or misappropriation.  CHI's OBLIGATIONS
         UNDER THIS PARAGRAPH SHALL BE FD'S SOLE AND EXCLUSIVE REMEDY FOR
         ANY ALLEGED INFRINGEMENT OF ANY PATENT, COPYRIGHT, TRADEMARK OR
         OTHER INTELLECTUAL PROPERTY RIGHT.

              14.  Covenant.  (a)  During the term of this Agreement, FD
                   --------          
         may not develop or enter into any arrangements with any entity for
         the sale of systems capable of measuring T-wave alternans without
         the express written permission of CHI.  This paragraph shall not
         apply to any products FD has dealt in the Territory on or before
         the date of the execution of this Agreement.

                   (b)  CHI may not during the term of this Agreement and
         any extension thereof directly or indirectly sell the Products by
         itself in the Territory.

              15.  Patents and Trademarks.  All patents and patent rights,
                   ---------------------- 
         trademarks, copyrights, tradenames and other property rights in
         and with respect to the Products shall exclusively belong to CHI.
         Solely for the purpose of marketing Products, FD may, during the
         term of this Agreement and any extension thereof, indicate that it
         is an authorized distributor for Products and may advertise the
         Same under the trademark for the Products of CHI.  FD shall
         provide timely copies to CHI of all advertising using any
         tradenames, trademarks, servicemarks, or logos of CHI, and, when
         used, shall appropriately credit CHI.

              16.  Confidentiality.  Both Parties shall keep confidential
                   ---------------

         without limitation, the Software) and business information
         acquired from the other pursuant to this Agreement except as
         authorized in writing by the other.

              17.  Termination.  (a)  Either Party may terminate this
                   -----------
         Agreement at any time by written notice as follows:

                        (i)  If the other Party fails to perform or comply
         with any material provision or conditions of this Agreement and
         fails to remedy such default within thirty (30) days after receipt
         of written notice thereof;

                        (ii)  If any case, proceeding or other action is
         commenced by or against the other Party seeking to have an order
         for relief entered on that Party's behalf as debtor or to
         adjudicate that Party as bankrupt or insolvent, or seeking the
         reorganization, arrangement, adjustment, liquidation, dissolution
         or composition of that Party's debts.

                        (iii)  If either Party sells all or substantially all
         of its assets or any patent, patent right, trademark, copyright,
         tradenames or other property right necessary for manufacturing and
         selling the Products, liquidate, be bought by or merged into
         another company and, in the case of a merger, does not own greater
         than fifty percent (50%) of the surviving shares.

                   (b)  In addition, FD may terminate this Agreement by
         timely notice if:

                        (i)  CHI materially delays the delivery of the Demo
         Units.

                        (ii)  The Demo Units fail to meet the
         Specifications, including the FD's Improvements, or have a
         material problem with quality or reliability and such failure to
         meet the Specification or problem has not been cured by CHI within
         ninety (90) days of a timely notice by FD.

              18.  Effect of Termination.  (a)   Upon termination or
                   ---------------------

                   (f)  Termination or expiration of this Agreement shall
         not affect the rights of any Software licensee not affiliated with
         FD and, to the extent the licenses under this Agreement apply to

                                APPENDIX E:  Warranty

         A.   CHI warrants for a period of fifteen (15) months from
         shipment by CHI to FD, or twelve (12) months from shipment by FD
         to its customer, whichever is shorter ("Warranty Period"), that
         the Product shall conform to CHI's standard specifications and
         shall be free from defences in material and workmanship under
         normal and proper use in accordance with any instructions and
         directions of CHI applicable thereto; provided, however, in case
         FD receives any claim of or relating to such warranty from FD's
         customers during the Warranty Period and such claim shall be
         forwarded by FD to CHI within thirty (30) days thereafter, such
         claim shall be deemed made in a timely fashion, notwithstanding
         the expiration of the Warranty Period.  Such warranty shall not
         apply in circumstances that would be excluded by CHI's standard
         end user warranty terms, such as misuse or alteration of the
         Product or use of the Product for other than the specific purpose
         for which it is designed.  CHI's sole obligation under such
         hardware warranty shall be to repair or replace, at CHI's option,
         the defective or non-conforming hardware.  CHI's sole obligation
         under such Software warranty shall be to:  (i) accept, analyze and
         provide written response to any reports from FD of Software
         malfunction or error, and (ii) use best efforts to provide
         responses to correct such errors when they reflect significant
         deviations from CHI's design specifications for the current
         release of the Software.  The time required to repair or replace
         any defective Product shall not extend the Warranty Period.

         B.   FD shall provide the necessary personnel to replace any
         defective parts at [FD's/CHI's] expense and to provide a 12-month
         parts and labor warranty to its customers of the Products.

         C.   CHI shall indemnify, protect and save FD harmless from any
         and all claims, demands, litigations or actions, including but not
         limited to reasonable actions, including but not limited to
         reasonable attorney's fees incurred in connection therewith, which
         may be asserted by any third party against FD for Product
         Liability regardless of the Warranty Period.  "Product Liability"
         means the liability for damages or injuries to lives, bodies and
         properties of users of the Products or third parties, which is
         caused by lack of insufficiency of reasonably experienced safety
         of Products, other than any of same as may be caused by the
         negligence or willful misconduct of FD or its employees or agents.

         D.   THE EXPRESS WARRANTIES SET FORTH IN PARAGRAPH A CONSTITUTE
         THE ONLY WARRANTIES WITH RESPECT TO THE PRODUCTS.  CHI MAKES NO
         REPRESENTATION OR WARRANTY OF ANY OTHER KIND, EXPRESS OR IMPLIED


                                        -16-

         (EITHER IN FACT OR BY OPERATION OF LAW), WITH RESPECT TO THE
         PRODUCTS, WHETHER AS TO MERCHANTABILITY, FITNESS FOR A PARTICULAR
         PURPOSE (EXCEPT THE PERFORMANCE OF STRESS TEST AS PROVIDED IN AND
         IN ACCORDANCE WITH CHI'S PRODUCT DOCUMENTATION), OR ANY OTHER
         MATTER.

         E.   NEITHER PARTY SHALL BE LIABLE FOR ANY SPECIAL, INCIDENTAL,
         INDIRECT OR CONSEQUENTIAL DAMAGES OF THE OTHER PARTY OR ANYONE
         CLAIMING THROUGH OR ON BEHALF OF SUCH OTHER PARTY.  THIS
         LIMITATION OF LIABILITY EXTENDS TO THE LOSS OF ACTUAL OR
         ANTICIPATED USE, REVENUE, OR PROFITS IN CONNECTION WITH OR ARISING
         OUT OF THIS AGREEMENT OR ANY BREACH OF THIS AGREEMENT OR THE
         EXISTENCE, FURNISHING, FUNCTIONING, OR THE OTHER PARTY'S OR ANY
         THIRD PARTY'S USE, OF ANY PRODUCTS OR SERVICES PROVIDED FOR IN
         THIS AGREEMENT, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE
         POSSIBILITY OF SUCH DAMAGES.  SUCH LIMITATION OF LIABILITY SHALL
         NOT EXTEND TO ANY CLAIM BY FD AGAINST CHI FOR DAMAGES AGAINST FD
         FOR PERSONAL INJURY TO A USER OF A PRODUCT TO THE EXTENT CAUSED BY
         THE LACK OR INSUFFICIENCY OF REASONABLY EXPECTED SAFETY OF THE
         PRODUCTS UNDER NORMAL AND PROPER USE IN ACCORDANCE WITH ANY
         INSTRUCTIONS AND DIRECTIONS OF CHI APPLICABLE THERETO.

         F.   THIS WARRANTY IS VALID ONLY IN JAPAN.

                APPENDIX F:  Software License Agreement for End Users

              This is a legal agreement between you (either individual or
         entity), the end user, and Cambridge Heart, Inc. ("CHI").

                          CAMBRIDGE HEART LICENSE AGREEMENT

         Grant of License.  Upon acceptance by CHI, CHI grants to you the
         ----------------
         right to use one copy of the CHI software program identified above
         (the "Software") on the single computer on which the software is
         initially installed by CHI (the "Dedicated Computer") in the
         country indicated across from your signature below.

         Ownership; Copyright.  As the licensee, you own the physical media
         --------------------
         on which the Software is originally or subsequently recorded, but
         CHI and its licensors (if any) retain title and ownership of the
         Software recorded on the original disk or other media and all
         subsequent copies of the Software, regardless of the form or media
         in or on which the original and other copies may exist.  This
         license is not a sale of the original Software or any copy
         thereof.  The Software and the accompanying written materials are
         patented and copyrighted and are protected by United States patent
         and copyright laws and international treaty provisions, and
         further, contain trade secret and proprietary information.
         Therefore, you must treat the Software like any other patented and
         copyrighted material (e.g., a book or musical recording) and trade
         secret information.  Subject to these restrictions, you may either
         (a) make one copy of the Software solely for backup purposes in
         support of your permitted use of the Software on the Dedicated
         Computer, or (b) transfer the Software to a single hard disk on
         the Dedicated Computer provided you keep the original solely for
         backup purpose.  (Programs, however, may include mechanisms to
         limit or inhibit copying, and they are marked "copy protected";
         programs on CD-ROM will not be copyable.)  The patent, copyright
         and other notices must be reproduced on the backup copy.  You may
         not copy the written materials accompanying the Software.

         Other Restrictions.  You may not rent or lease the Software, but
         ------------------
         you may transfer your rights under this Agreement on a permanent
         basis in conjunction with your transfer of the Dedicated Computer,
         provided at the same time you transfer the Software (including all
         copies, whether in printed, machine readable form or otherwise,
         and all accompanying written materials) and Dedicated Computer you
         retain no copies, the recipient agrees in writing to accept the
         terms of this Agreement and such writing is delivered to and
         accepted by CHI.  Any such transfer, or any transfer of possession
         of any Software in whole or in part to another party, shall
         automatically terminate your license.  If the Software is an


                                        -18-

         update, any transfer must include the update and all prior
         versions.  YOU MAY NOT DISTRIBUTE COPIES OF THE SOFTWARE OR THE
         ACCOMPANYING WRITTEN MATERIALS TO OTHERS.  YOU MAY NOT MODIFY,
         ADAPT, TRANSLATE, REVERSE ENGINEER, DECOMPILE, DISASSEMBLE, OR
         CREATE DERIVATIVE WORKS BASED ON THE SOFTWARE OR THE WRITTEN
         MATERIALS.

         Dual Media Software.  If the Software package contains both
         -------------------
         diskettes and CD-ROM, then you may use only the media appropriate
         for your single Dedicated Computer.  You may not use the other
         media on another computer or computer network, or loan, rent,
         lease or transfer it to another user except as part of a transfer
         or other use as expressly permitted by this Agreement.

         Limited Warranty.  CHI does not warrant that the functions
         ----------------

         gross proceeds to the Company of at least $10,000,000 (before
         deducting underwriting discounts and commissions and expenses) and
         a price to the public of at least $3.00 per share (subject to

         of the shares referenced in (i) and (ii) above, excluding in all

         assigned.

                   (k)  The term "SEC" shall mean the Securities and
         Exchange Commission.

              1.2  Request for Registration.
                   ------------------------

                   (a)  If the Company shall receive at any time after the
         earlier of (i) three (3) years after the Closing (as defined in
         Section 1.2 of the Stock Purchase Agreement) or (ii) six (6)
         months after the effective date of the first registration
         statement for a public offering of securities of the Company
         (other than an Excluded Registration), a written request from the
         Investors that the Company file a registration statement under the

         Act covering the registration of Registrable Securities then
         outstanding with a reasonably anticipated aggregate offering price
         of at least $2,500,000, the Company shall:

                        (i)  within ten (10) days of the receipt thereof,
         give written notice, in accordance with Section 3.5 hereof, of
         such request to all Holders; and


                                        -2-


<PAGE>
 
                       (ii)  file as soon as practicable, and in any event
         within ninety (90) days of the receipt of such request with
         respect to a Form S-1 and within sixty (60) days of the receipt of
         such request with respect to a Form S-3, and use its best efforts
         to cause to become effective as soon as practicable, the
         registration under the Act of all Registrable Securities which the
         Investors and any other Holders request to be registered, subject
         to the limitations of Subsection 1.2(b).

                   (b)  If the Investors intend to distribute the
         Registrable Securities covered by their request by means of an
         underwriting, they shall so advise the Company as a part of their
         request made pursuant to Subsection 1.2(a), and the Company shall
         include such information in the written notice referred to in
         Subsection 1.2(a).  The underwriter will be selected by the
         Company and shall be reasonably acceptable to a majority in
         interest of the Investors.  In such event, the right of any Holder
         to include his, her or its Registrable Securities in such
         registration shall be conditioned upon such Holder's participation
         in such underwriting and the inclusion of such Holder's
         Registrable Securities in the underwriting (unless otherwise
         mutually agreed by a majority in interest of the Investors and
         such Holder) to the extent provided herein.  All Holders proposing
         to distribute their securities through such underwriting shall
         (together with the Company as provided in Subsection 1.4(e)) enter
         into an underwriting agreement in customary form with the
         underwriter or underwriters selected for such underwriting.
         Notwithstanding any other provision of this Section 1.2, if the
         underwriter advises the Investors in writing that marketing
         factors require a limitation of the number of shares to be
         underwritten, then the Investors shall so advise all Holders of
         Registrable Securities which would otherwise be underwritten
         pursuant hereto, and the number of shares of Registrable
         Securities that may be included in the underwriting shall be
         allocated among all Holders thereof, including the Investors, in
         proportion (as nearly as practicable) to the amount of Registrable
         Securities of the Company owned by each Holder; provided, however,
         that the number of shares of Registrable Securities to be included
         in such underwriting shall not be reduced unless all other
         securities are first entirely excluded from the underwriting.

                   (c)  Notwithstanding the foregoing, if the Company shall
         furnish to the Investors a certificate signed by the Chief
         Executive Officer of the Company stating that, in the good faith
         judgment of the Board of Directors of the Company, it would be
         seriously detrimental to the Company and its stockholders for such
         registration statement to be filed and it is therefore essential
         to defer the filing of such registration statement, the Company
         shall have the right to defer taking action with respect to such
         filing for a period of not more than ninety (90) days after
         receipt of the request of the Investors; provided, however, that
         the Company may not utilize this right more than once in any
         twelve (12) month period.



                                        -3-

                                       
<PAGE>
 
                   (d)  In addition, the Company shall not be obligated to
         effect, or to take any action to effect, any registration pursuant
         to this Section 1.2:

                        (i)  After the Company has effected two (2)
         registrations pursuant to this Section 1.2, excluding any
         registrations effected on Form S-3, and such registrations have
         been declared or ordered effective;

                       (ii)  During the period starting with the date sixty
         (60) days prior to the Company's good faith estimate of the date
         of filing of, and ending on a date one hundred eighty (180) days
         after the effective date of, the first registration statement for
         a public offering subject to Section 1.3 hereof; provided that the
         Company is actively employing in good faith all reasonable efforts
         to cause such registration statement to become effective;

                      (iii)  During the period starting with the date sixty
         (60) days prior to the Company's good faith estimate of the date
         of filing of, and ending on a date ninety (90) days after the
         effective date of, any subsequent registration statement for a
         public offering subject to Section 1.3 hereof; provided that the
         Company is actively employing in good faith all reasonable efforts
         to cause such registration statement to become effective;

                       (iv)  If the Investors propose to dispose of shares
         of Registrable Securities that may be immediately registered on
         Form S-3 pursuant to a request made pursuant to Section 1.12
         below; or

                        (v)  If the Company delivers to the Investors an
         opinion, in form and substance reasonably acceptable to such
         Investors, of counsel reasonably satisfactory to the Investors
         that the Registrable Securities requested to be registered by the
         Investors may be sold or transferred pursuant to Rule 144(k) of
         the Act.

              1.3  Company Registration.  If (but without any obligation to
                   --------------------
         do so) the Company proposes to register (including for this
         purpose a registration effected by the Company for stockholders
         other than the Holders) any of its stock or other securities under
         the Act in connection with the public offering of such securities
         (other than an Excluded Registration, a registration on any form
         which does not include substantially the same information as would
         be required to be included in a registration statement covering
         the sale of the Registrable Securities or a registration in which
         the only Common Stock being registered is Common Stock issuable
         upon conversion of debt securities which are also being
         registered), the Company shall, at such time, promptly give each
         Holder written notice of such registration.  Upon the written
         request of each Holder given within twenty (20) days after giving


                                        -4-

                                       
<PAGE>
 
         of such notice by the Company in accordance with Section 3.5, the
         Company shall, subject to the provisions of Section 1.8, cause to
         be registered under the Act all of the Registrable Securities that
         each such Holder has requested to be registered.  Neither the
         giving of any notice nor the making of any request hereunder shall
         impose any obligation on a Holder to sell any shares.

              1.4  Obligations of the Company.  Whenever required under
                   --------------------------
         this Section 1 to effect the registration of any Registrable
         Securities, the Company shall, as expeditiously as reasonably
         possible:

                   (a)  Prepare and file with the SEC a registration
         statement with respect to such Registrable Securities and use its
         best efforts to cause such registration statement to become
         effective, and keep such registration statement effective for a
         period of up to one hundred twenty (120) days or until the
         distribution contemplated in the Registration Statement has been
         completed, whichever first occurs; provided, however, that such
         one hundred twenty (120) day period shall be extended for a period
         of time equal to the period the Holder refrains from selling any
         securities included in such registration at the request of an
         underwriter of Common Stock (or other securities) of the Company,
         and provided further that in the case of any registration of
         Registrable Securities on Form S-3 that are intended to be offered
         on a continuous or delayed basis, such one hundred twenty (120)
         day period shall be extended until all such Registrable Securities
         are sold, if applicable rules under the Act governing the
         obligation to file a post-effective amendment permit, in lieu of
         filing a post-effective amendment which (I) includes any
         prospectus required by Section 10(a)(3) of the Act or (II)
         reflects facts or events representing a material or fundamental
         change in the information set forth in the registration statement,
         the incorporation by reference of information required to be
         included in (I) and (II) above to be contained in periodic reports
         filed pursuant to Section 13 or 15(d) of the 1934 Act in the
         registration statement.

                   (b)  Prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used
         in connection with such registration statement as, in the opinion
         of counsel to the Company, may be necessary to comply with the
         provisions of the Act with respect to the disposition of all
         securities covered by such registration statement.

                   (c)  Furnish to the Holders such numbers of copies of a
         prospectus, including a preliminary prospectus, in conformity with
         the requirements of the Act, and such other documents as they may
         reasonably request in order to facilitate the disposition of
         Registrable Securities owned by them.

                   (d)  Use its best efforts to register and qualify the
         securities covered by such registration statement under such other


                                        -5-

                                       
<PAGE>
 
         securities or Blue Sky laws of such jurisdictions as shall be
         reasonably requested by the Holders; provided that the Company
         shall not be required in connection therewith or as a condition
         thereto to qualify to do business or to file a general consent to
         service of process in any such states or jurisdictions, unless the
         Company is already subject to service in such jurisdiction and
         except as may be required by the Act.

                   (e)  In the event of any underwritten public offering,
         enter into and perform its obligations under an underwriting
         agreement, in usual and customary form, with the managing
         underwriter of such offering.  Each Holder participating in such
         underwriting shall also enter into and perform its obligations
         under such an agreement.

                   (f)  Notify each Holder of Registrable Securities
         covered by such registration statement at any time when a
         prospectus relating thereto is required to be delivered under the
         Act of 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 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.

                   (g)  Cause all such Registrable Securities registered
         pursuant hereunder to be listed on each securities exchange on
         which similar securities issued by the Company are then listed.
         If no similar securities issued by the Company are then listed on
         an exchange, facilitate the reporting of the Registrable
         Securities on NASDAQ.

                   (h)  Provide a transfer agent and registrar for all
         Registrable Securities registered hereunder and a CUSIP number for
         all such Registrable Securities, in each case not later than the
         effective date of such registration.

                   (i)  Take all other reasonable actions necessary to
         expedite and facilitate disposition by the Investors of the
         Registrable Securities pursuant to the registration statement.

              1.5  Furnish Information.
                   -------------------

                   (a)  It shall be a condition precedent to the
         obligations of the Company to take any action pursuant to this
         Section 1 with respect to the Registrable Securities of any
         selling Holder that such Holder shall furnish to the Company such
         information regarding itself, the Registrable Securities held by
         it, and the intended method of disposition of such securities as
         shall be required to effect the registration of such Holder's
         Registrable Securities.

                   (b)  The Company shall have no obligation with respect
         to any registration requested pursuant to Section 1.2 or Section


                                        -6-

         1.12 if, due to the operation of Subsection 1.5(a), the
         anticipated aggregate offering price of the Registrable Securities
         to be included in the registration does not equal or exceed the
         anticipated aggregate offering price required to originally
         trigger the Company's obligation to initiate such registration as
         specified in Subsection 1.2(a) or Subsection 1.12(b)(2), whichever
         is applicable.

              1.6  Expenses of Demand Registration.  All expenses other
                   -------------------------------
         than underwriting discounts and commissions incurred in connection
         with registrations, filings or qualifications pursuant to Section
         1.2, including (without limitation) all registration, filing and
         qualification fees, printers' and accounting fees, fees and
         disbursements of counsel for the Company and the reasonable fees
         and disbursements of one counsel for the selling Holders shall be
         borne by the Company.

              1.7  Expenses of Company Registration.  The Company shall
                   --------------------------------
         bear and pay all expenses incurred in connection with any
         registration, filing or qualification of Registrable Securities
         with respect to the registrations pursuant to Section 1.3 for each
         Holder, including (without limitation) all registration, filing,
         and qualification fees, printers' and accounting fees relating or
         apportionable thereto and the reasonable fees and disbursements of
         one counsel for the selling Holders, but excluding underwriting
         discounts and commissions relating to Registrable Securities.


              1.8  Underwriting Requirements.  In connection with any
                   -------------------------
         offering involving an underwriting of shares of the Company's
         capital stock, the Company shall not be required under Section 1.3
         to include any of a Holder's securities in such underwriting
         unless such Holder accepts the terms of the underwriting as agreed
         upon between the Company and the underwriters selected by it (or
         by other persons entitled to select the underwriters), and then
         only in such quantity as the underwriters determine in their sole
         discretion will not jeopardize the success of the offering by the
         Company.  If the total amount of securities, including Registrable
         Securities, requested by stockholders to be included in such
         offering exceeds the amount of securities sold other than by the
         Company that the underwriters determine in their sole discretion
         is compatible with the success of the offering, then the Company
         shall be required to include in the offering only that number of
         such securities, including Registrable Securities, which the
         underwriters determine in their sole discretion will not
         jeopardize the success of the offering (the securities so included
         to be apportioned pro rata among the selling stockholders
         according to the total amount of securities entitled to be
         included therein owned by each selling stockholder or in such
         other proportions as shall mutually be agreed to by the selling
         stockholders).

              1.9  Delay of Registration.  No Holder shall have any right
                   ---------------------
         to obtain or seek an injunction restraining or otherwise delaying
         any such registration as the result of any controversy that might
         arise with respect to the interpretation or implementation of this
         Section 1.

              1.10  Indemnification.  In the event any Registrable
                    ---------------
         Securities are included in a registration statement under this
         Section 1:

                    (a)  To the extent permitted by law, the Company will
         indemnify and hold harmless each Holder, the officers and
         directors of each Holder participating in such registration, any
         underwriter (as defined in the Act) for such Holder and each
         person, if any, who controls such Holder or underwriter within the
         meaning of the Act or the 1934 Act, against any losses, claims,
         damages, or liabilities (joint or several) to which they may
         become subject under the Act, or the 1934 Act, or otherwise
         insofar as such losses, claims, damages, or liabilities (or
         actions in respect thereof) arise out of or are based upon any of
         the following statements, omissions or violations (collectively a
         "Violation"):  (i) any untrue statement or alleged untrue
         statement of a material fact contained in such registration
         statement, including any preliminary prospectus or final
         prospectus contained therein or any amendments or supplements
         thereto, (ii) the omission or alleged omission to state therein a
         material fact required to be stated therein, or necessary to make
         the statements therein not misleading, or (iii) any violation or
         alleged violation by the Company of the Act, the 1934 Act, or any
         rule or regulation promulgated under the Act, or the 1934 Act, and
         the Company will pay to each such Holder, underwriter or
         controlling person, as incurred, any legal or other expenses
         reasonably incurred by them in connection with investigating or
         defending any such loss, claim, damage, liability, or action;
         provided, however, that the indemnity agreement contained in this
         Subsection 1.10(a) shall not apply to amounts paid in settlement
         of any such loss, claim, damage, liability, or action if such
         settlement is effected without the consent of the Company, which
         consent shall not be unreasonably withheld, nor shall the Company
         be liable in any such case for any such loss, claim, damage,
         liability, or action to the extent that it arises out of or is
         based upon a Violation which occurs in reliance upon and in
         conformity with written information furnished expressly for use in
         connection with such registration by any such Holder, underwriter
         or controlling person.  With respect to any untrue statement or
         alleged untrue statement made in, or omission or alleged omission
         from, any preliminary prospectus or prospectus, the indemnity
         agreement contained in this Section 1.10(a) with respect to such
         preliminary prospectus or prospectus, to the extent it is based on
         the claim of a person who purchased any Registrable Securities
         directly from a Holder shall not inure to the benefit of such
         Holder (or to the benefit of any of its officers and directors or
         any person controlling such Holder) if the prospectus (or the
         prospectus as amended or supplemented if the Company shall have


                                        -8-

                                       
<PAGE>
 
         filed with the Commission any amendment or supplement thereto)
         which shall have been furnished to such Holder by the Company in a
         timely manner and in sufficient quantities, does not contain such
         statement, alleged statement, omission, or alleged omission and a
         copy of the prospectus (or the prospectus as amended or
         supplemented if the Company shall have filed with the Commission
         any amendment or supplement thereto) shall not have been sent or
         given to such person by the Holder (and the Holder shall have been
         obligated so to furnish such a prospectus) and such person shall
         not otherwise have received a copy thereof at or prior to the
         written confirmation of such sale to such person.

                    (b)  To the extent permitted by law, each selling
         Holder will indemnify and hold harmless the Company, each of its
         directors, each of its officers who has signed the registration
         statement, each person, if any, who controls the Company within
         the meaning of the Act, any underwriter, any other Holder selling
         securities in such registration statement and any controlling
         person of any such underwriter or other Holder, against any
         losses, claims, damages, or liabilities (joint or several) to
         which any of the foregoing persons may become subject, under the
         Act, or the 1934 Act, insofar as such losses, claims, damages, or
         liabilities (or actions in respect thereto) arise out of or are
         based upon any Violation, in each case to the extent (and only to
         the extent) that such Violation occurs in reliance upon and in
         conformity with written information furnished by such Holder
         expressly for use in connection with such registration; and each
         such Holder will pay, as incurred, any legal or other expenses
         reasonably incurred by any person intended to be indemnified
         pursuant to this Subsection 1.10(b), in connection with
         investigating or defending any such loss, claim, damage,
         liability, or action; provided, however, that the indemnity
         agreement contained in this Subsection 1.10(b) shall not apply to
         amounts paid in settlement of any such loss, claim, damage,
         liability or action if such settlement is effected without the
         consent of the Holder, which consent shall not be unreasonably
         withheld; provided, that, in no event shall any selling Holder's
         liability under this Subsection 1.10(b) exceed the proceeds
         received by such Holder from the offering (net of any underwriting
         discounts and commissions)

                    (c)  Promptly after receipt by an indemnified party
         under this Section 1.10 of notice of the commencement of any
         action (including any governmental action), such indemnified party
         will, if a claim in respect thereof is to be made against any
         indemnifying party under this Section 1.10, deliver to the
         indemnifying party a written notice of the commencement thereof
         and the indemnifying party shall have the right to participate in,
         and, to the extent the indemnifying party so desires, jointly with
         any other indemnifying party similarly noticed, to assume the
         defense thereof with counsel mutually satisfactory to the parties;
         provided, however, that an indemnified party (together with all
         other indemnified parties which may be represented without


                                        -9-

                                       
<PAGE>
 
         conflict by one counsel) shall have the right to retain one
         separate counsel, with the fees and expenses to be paid by the
         indemnifying party, if representation of such indemnified party by
         the counsel retained by the indemnifying party would be
         inappropriate due to actual or potential differing interests
         between such indemnified party and any other party represented by
         such counsel in such proceeding.  The failure to deliver written
         notice to the indemnifying party within a reasonable time of the
         commencement of any such action, if prejudicial to its ability to
         defend such action, shall relieve such indemnifying party of any
         liability to the indemnified party under this Section 1.10, but
         the omission so to deliver written notice to the indemnifying
         party will not relieve it of any liability that it may have to any
         indemnified party otherwise than under this Section 1.10.

                    (d)  If the indemnification provided for in this
         Section 1.10 is held by a court of competent jurisdiction to be
         unavailable to an indemnified party with respect to any loss,
         liability, claim, damage, or expense referred to therein, then the
         indemnifying party, in lieu of indemnifying such indemnified party
         hereunder, shall contribute to the amount paid or payable by such
         indemnified party as a result of such loss, liability, claim,
         damage, or expense in such proportion as is appropriate to reflect
         the relative fault of the indemnifying party on the one hand and
         of the indemnified party on the other in connection with the
         statements or omissions that resulted in such loss, liability,
         claim, damage, or expense as well as any other relevant equitable
         considerations.  The relative fault of the indemnifying party and
         of the indemnified party shall be determined by reference to,
         among other things, whether the untrue or alleged untrue statement
         of a material fact or the omission to state a material fact
         relates to information supplied by the indemnifying party or by
         the indemnified party and the parties' relative intent, knowledge,
         access to information, and opportunity to correct or prevent such
         statement or omission.

                    (e)  Notwithstanding the foregoing, to the extent that
         the provisions on indemnification and contribution contained in
         the underwriting agreement entered into in connection with the
         underwritten public offering are in conflict with the foregoing
         provisions, the provisions in the underwriting agreement shall
         control.

                    (f)  The obligations of the Company and Holders under
         this Section 1.10 shall survive the completion of any offering of
         Registrable Securities in a registration statement under this
         Section 1, and otherwise.

              1.11  Reports Under Securities Exchange Act of 1934.  With a
                    ---------------------------------------------
         view to making available to the Holders the benefits of Rule 144
         promulgated under the Act and any other rule or regulation of the
         SEC that may at any time permit a Holder to sell securities of the
         Company to the public without registration or pursuant to a
         registration on Form S-3, the Company agrees to:


                                       -10-

                                       
<PAGE>
 
                    (a)  make and keep public information available, as
         those terms are understood and defined in SEC Rule 144, at all
         times after ninety (90) days after the effective date of the first
         registration statement filed under the Act by the Company for the
         offering of its securities to the general public;

                    (b)  take such action, including the voluntary
         registration of its Common Stock under Section 12 of the 1934 Act,
         as is necessary to enable the Holders to utilize Form S-3 for the
         sale of their Registrable Securities, such action to be taken as
         soon as practicable after the end of the fiscal year in which the
         first registration statement filed under the Act by the Company
         for the offering of its securities to the general public is
         declared effective;

                    (c)  file with the SEC in a timely manner all reports
         and other documents required of the Company under the Act and the
         1934 Act; and

                    (d)  furnish to any Holder, so long as the Holder owns
         any Registrable Securities, forthwith upon request (i) a written
         statement by the Company that it has complied with the reporting
         requirements of SEC Rule 144 (at any time after ninety
         (90) days after the effective date of the first registration
         statement filed by the Company), the Act and the 1934 Act (at any
         time after it has become subject to such reporting requirements),
         (ii) a copy of the most recent annual or quarterly report of the
         Company and such other reports and documents so filed by the
         Company, and (iii) such other information as may be reasonably
         requested in availing any Holder of any rule or regulation of the
         SEC which permits the selling of any such securities without
         registration or pursuant to such form.

              1.12  Form S-3 Registration.  In case the Company shall
                    ---------------------
         receive at any time after six months following the completion of
         the first registration statement for a public offering of
         securities of the Company (other than an Excluded Registration), a
         written request from the Investors that the Company effect a
         registration on Form S-3 and any related qualification or
         compliance with respect to all or a part of the Registrable
         Securities owned by such Investors, the Company will:

                    (a)  promptly give written notice of the proposed
         registration, and any related qualification or compliance, to all
         other Holders; and

                    (b)  as soon as practicable, use its best efforts to
         effect such registration and all such qualifications and
         compliances as may be so requested and as would permit or
         facilitate the sale and distribution of all or such portion of
         such Investors' Registrable Securities as are specified in such
         request, together with all or such portion of the Registrable
         Securities of any other Holder or Holders joining in such request

         as are specified in a written request given within twenty (20)
         days after receipt of such written notice from the Company;
         provided, however, that the Company shall not be obligated to
         effect any such registration, qualification or compliance,
         pursuant to this Section 1.12: (1) if Form S-3 is not available
         for such offering by the Holders; (2) if the Investors, together
         with the Holders of any other securities of the Company entitled
         to inclusion in such registration, propose to sell Registrable
         Securities and such other securities (if any) at an aggregate
         price to the public (net of any underwriting discounts or
         commissions) of less than $500,000; (3) if the Company shall
         furnish to the Investors a certificate signed by the President of
         the Company stating that, in the good faith judgment of the Board
         of Directors of the Company, it would be seriously detrimental to
         the Company and its shareholders for such Form S-3 Registration to
         be effected at such time, in which event the Company shall have
         the right to defer the filing of the Form S-3 registration
         statement for a period of not more than ninety (90) days after
         receipt of the request of the Investors under this Section 1.12;
         provided, however, that the Company shall not utilize this right
         more than once in any twelve (12) month period; (4) if the Company
         has already effected three (3) registrations on Form S-3, or any
         equivalent successor form, for the Holders pursuant to this
         Section 1.12; or (5) in any particular jurisdiction in which the
         Company would be required to qualify to do business or to execute
         a general consent to service of process in effecting such
         registration, qualification or compliance.

                    (c)  Subject to the foregoing, the Company shall file a
         registration statement covering the Registrable Securities and
         other securities so requested to be registered as soon as
         practicable after receipt of the request or requests of the
         Investors.  All expenses incurred in connection with a
         registration requested pursuant to this Section 1.12, including,
         without limitation, all registration, filing, qualification,
         printers' and accounting fees and the reasonable fees and
         disbursements of one (1) counsel for the selling Holders and
         counsel for the Company, but excluding any underwriting discounts
         or commissions associated with Registrable Securities, shall be
         borne by the Company.  Registrations effected pursuant to this
         Section 1.12 shall not be counted as registrations effected
         pursuant to Sections 1.2 or 1.3.

                    (d)  The Company shall not be obligated to effect any
         registration pursuant to this Section 1.12 if the Company delivers
         to the Investors requesting registration under this Section 1.12
         an opinion, in form and substance acceptable to such Investors, of
         counsel satisfactory to the Investors, that the Registrable
         Securities so requested to be registered may be sold or
         transferred pursuant to Rule 144(k) under the Act.

              1.13  Assignment of Registration Rights.  The rights to cause
                    ---------------------------------
         the Company to register Registrable Securities pursuant to this
         Section 1 may be assigned (but only with all related obligations)

         by an Investor to:  (i) in the case of an Investor that is an
         investment company registered under the Investment Company Act of
         1940, to another such investment company (a "Related Mutual Fund")
         that has the same investment adviser as the transferring
         investment company, without restriction or requirement as to
         number of shares; or (ii) to a transferee or assignee of such
         securities who, as a result of such assignment or transfer,
         acquires at least fifty percent (50%) of such transferring
         Investor's shares of Registrable Securities (in either such case,
         a "Permitted Transferee"), provided:  (a) the Company is, within a
         reasonable time after such transfer, furnished with written notice
         of the name and address of such transferee or assignee and the
         securities with respect to which such registration rights are
         being assigned; (b) such transferee or assignee agrees in writing
         to be bound by and subject to the terms and conditions of this
         Agreement, including without limitation the provisions of Section
         1.14 below; and (c) such assignment shall be effective only if
         immediately following such transfer the further disposition of
         such securities by the transferee or assignee is restricted under
         the Act.

              1.14  "Market Stand-Off" Agreement.  Each Investor hereby
                    ----------------------------
         agrees that, during the period of duration specified by the
         Company and an underwriter of Common Stock or other securities of
         the Company, following the effective date of a registration
         statement of the Company filed under the Act, it shall not, to the
         extent requested by the Company and such underwriter, directly or
         indirectly sell, offer to sell, contract to sell (including,
         without limitation, any short sale), grant any option to purchase
         or otherwise transfer or dispose of (other than to donees who
         agree to be similarly bound) any securities of the Company held by
         it at any time during such period except Common Stock included in
         such registration; provided, however:

                    (a)  that such market stand-off time period shall not
         exceed one hundred eighty (180) days following the effective date
         of the Company's first registration of Common Stock or other
         securities under the Act and ninety (90) days following the
         effective date with respect to all subsequent registrations; and

                    (b)  all officers and directors of the Company and all
         five percent (5%) or greater stockholders of the Company enter
         into similar agreements.

              In order to enforce the foregoing covenant, the Company may
         impose stop-transfer instructions with respect to the Registrable
         Securities of each Investor (and the shares or securities of every
         other person subject to the foregoing restriction) until the end
         of such period.

              Notwithstanding the foregoing, the obligations described in
         this Section 1.14 shall not apply to an Excluded Registration.

              1.15  Termination of Registration Rights.  No Investor shall
                    ----------------------------------
         be entitled to exercise any right provided for in this Section 1
         after five (5) years following the effective date of the Company's
         first registration of Common Stock or other securities under the
         Act, other than an Excluded Registration.

              1.16  Additional Registration Rights.  The registration
                    ------------------------------
         rights provided to the Investors in this Agreement are in addition
         to, and not in lieu of, the rights and obligations of the
         Investors pursuant to a Registration Agreement of even date
         herewith among the Company, the Investors and the other purchasers
         of Series A Preferred Stock named therein.

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

              2.1  Financial Statements and Other Information.  Except as
                   ------------------------------------------
         otherwise set forth below in this Section 2.1, until the Company
         is subject to the reporting requirements of the 1934 Act, the
         Company will deliver to each of the Investors, for so long as such
         Investor holds any shares of the Company's Series A Preferred
         Stock (or Common Stock issued upon conversion thereof)

                   (a)  as soon as available, but in any event within sixty
         (60) days after the end of each quarterly accounting period in
         each fiscal year, unaudited consolidated statements of operations
         and consolidated cash flows of the Company and its subsidiaries
         for such quarterly period and for the period from the beginning of
         the fiscal year to the end of such quarter, and consolidated
         balance sheets of the Company and its subsidiaries as of the end
         of such quarterly period, setting forth in each case comparisons
         to the annual budget and to the corresponding period in the
         preceding fiscal year, and all such statements will be prepared in
         accordance with generally accepted accounting principles,
         consistently applied (except for the absence of notes and subject
         to normal year-end adjustments);

                   (b)  as promptly as possible (but in any event within
         one hundred twenty (120) days) after the end of each fiscal year,
         consolidated statements of operations and a consolidated statement
         of cash flows of the Company and its subsidiaries for such fiscal
         year and consolidated balance sheets and statements of
         stockholders' equity of the Company and its subsidiaries as of the
         end of such fiscal year, setting forth comparisons to the annual
         budget and to the preceding fiscal year, all prepared in
         accordance with generally accepted accounting principles,
         consistently applied, and accompanied by an unqualified opinion
         (except for qualifications regarding specified contingent
         liabilities) of an independent accounting firm selected by the
         Company's Board of Directors;

                   (c)  prior to the end of each fiscal year, an annual
         budget (approved by the Board of Directors) prepared on a monthly,
         consolidated basis for the Company and its subsidiaries for the
         succeeding fiscal year (displaying detailed anticipated statements


                                       -14-

         of operations and cash flows and balance sheets), and promptly
         upon preparation thereof any other significant budgets which the
         Company prepares and any revisions of such annual or other
         budgets;

                   (d)  promptly (and in any event within thirty (30) days)
         after the discovery or receipt of notice of any event or
         circumstance affecting the Company or its subsidiaries that is
         determined in good faith by the Company to be material to the
         Company and its subsidiaries, taken as a whole, including but not
         limited to, the filing of any material litigation against the
         Company or its subsidiaries, acquisitions, mergers, substantial
         sales of assets, significant regulatory action directly affecting
         the Company, the commencement of voluntary or involuntary
         bankruptcy proceedings, natural or other disasters, significant
         changes in management or directors, changes in auditors, and
         execution or termination of, or defaults under, material
         contracts, a letter from the Chief Executive Officer or Chief
         Financial Officer of the Company specifying the nature and period
         of existence thereof and, in the case of material litigation, what
         actions the Company and its subsidiaries have taken and propose to
         take with respect thereto;

                   (e)  promptly after transmission thereof, copies of all
         financial statements, proxy statements, reports and any other
         written communications which the Company sends to its stockholders
         generally and copies of all registration statements and all
         regular, special or periodic reports which it files with the SEC
         or with any securities exchange on which any of its securities are
         then listed, and copies of all press releases and other statements
         made available generally by the Company to the public; and

                   (f)  a notice specifying the terms of all sales of the
         Company's securities, promptly following the consummation thereof.

              Each of the financial statements referred to in this Section
         2.1 will be true and correct in all material respects and will
         fairly present the Company's consolidated financial position and
         results of operations as of the dates and for the periods stated
         therein, subject in the case of the unaudited financial statements
         to changes resulting from normal year-end audit adjustments (none
         of which would, alone or in the aggregate, be materially adverse
         to the Company's financial condition, operating results or
         business prospects).  The Company's obligation to provide to the
         Investors the materials described in Subsection (e) above will
         continue after the Company is subject to the reporting
         requirements of the 1934 Act and until the Investors no longer
         hold any shares of the Company's Series A Preferred Stock (or
         Common Stock issued upon conversion thereof)

              2.2  Inspection of Property.  Until the Company is subject to
                   ----------------------
         the reporting requirements of the 1934 Act, the Company will

<PAGE>
 
         permit each of the Investors, or any representatives designated by
         an Investor, upon reasonable notice and during normal business
         hours and such other times as an Investor may reasonably request,
         to (i) visit and inspect any of the properties of the Company and
         its subsidiaries, (ii) examine the corporate and financial records
         of the Company and its subsidiaries and make copies thereof or
         extracts therefrom, (iii) discuss the affairs, finances and
         accounts of the Company and its subsidiaries with the directors,
         senior management and independent accountants of the Company and
         its subsidiaries, and (iv) consult with and advise the management
         of the Company and its subsidiaries as to their affairs, finances
         and accounts; provided that such Investor or representative shall
         agree to hold any such copies or extracts in confidence and
         provided further that the Company reserves the right to withhold
         any information and to exclude such Investor or such
         representative from any meeting or portion thereof to the extent
         necessary to preserve attorney-client privilege.

              2.3  Board Visitation Rights.  Until the Company is subject
                   -----------------------
         to the reporting requirements of the 1934 Act, the Company shall
         invite a representative of the Investors to attend all meetings of
         its Board of Directors in a non-voting observer capacity and, in
         this respect, shall give such representative copies of all
         notices, minutes, consents, and other materials that it provides
         to its directors; provided that such representative shall agree to
         hold such materials in confidence and provided further that the
         Company reserves the right to withhold any information and to
         exclude such representative from any meeting or portion thereof to
         the extent necessary to preserve attorney-client privilege.

              2.4  Preemptive Right.  Subject to the terms and conditions
                   ----------------
         specified in this Section 2.4, the Company hereby grants to each
         Investor a preemptive right with respect to future sales by the
         Company of its Shares (as hereinafter defined).  An Investor shall
         be entitled to apportion the preemptive right hereby granted it
         among itself and its partners and affiliates and, in the case of
         an Investor that is a registered investment company, among itself
         and its Related Mutual Funds, in such proportions as it deems
         appropriate.

              Each time the Company proposes to offer any shares of, or
         securities convertible into or exercisable for any shares of, any
         class of its capital stock ("Shares"), the Company shall make an
         offering of such Shares to each Investor in accordance with the
         following provisions:

                   (a)  The Company shall deliver a notice ("Notice") to
         the Investors stating (i) its bona fide intention to offer such
         Shares, (ii) the number of such Shares to be offered, and (iii)
         the price and terms, if any, upon which it proposes to offer such
         Shares.


                                       -16-

                                       
<PAGE>
 
                   (b)  By written notification received by the Company,
         within twenty (20) calendar days after giving of the Notice, the
         Investor may elect to purchase or obtain, at the price and on the
         terms specified in the Notice, up to that portion of such Shares
         which equals the proportion that the number of shares of Common
         Stock issued and held, or issuable upon conversion of the Series A
         Preferred Stock then held, by such Investor bears to the total
         number of shares of Common Stock of the Company then outstanding
         (assuming full conversion of all convertible securities) ("Pro
         Rata Share").

                   (c)  If all Shares referred to in the Notice which
         Investors are entitled to obtain pursuant to Subsection 2.4(b) are
         not elected to be obtained as provided in Subsection 2.4(b)
         hereof, the Company may, during the ninety (90) day period
         following the expiration of the period provided in Subsection
         2.4(b) hereof, offer the remaining unsubscribed portion of such
         Shares to any person or persons at a price not less than, and upon
         terms no more favorable to the offeree than those specified in the
         Notice.  If the Company does not enter into an agreement for the
         sale of the Shares within such period, or if such agreement is not
         consummated within thirty (30) days of the execution thereof, the
         right provided hereunder shall be deemed to be revived and such
         Shares shall not be offered unless first reoffered to the
         Investors in accordance herewith.

                   (d)  The preemptive right in this Section 2.4 shall not
         be applicable to

                        (i)  shares of Common Stock issuable or issued to
         employees, advisors, consultants or outside directors of the
         Company directly or pursuant to a stock option plan or restricted
         stock plan approved by the Board of Directors of the Company so
         long as the cumulative total number of shares of Common Stock so
         issuable and issued (and not repurchased at cost by the Company in
         connection with the termination of employment) does not exceed at
         any time the greater of (i) 2.75 million shares of Common Stock or
         (ii) twelve percent (12%) of the outstanding shares of Common
         Stock (assuming the exercise or conversion into Common Stock of
         all securities then outstanding that are exercisable for or
         convertible into Common Stock);

                       (ii)  Common Stock issued in connection with bona
         fide research, licensing or corporate partnering relationships, in
         connection with equipment lease financings, or upon exercise of
         warrants issued to institutional lenders in connection with
         non-convertible debt financings, in each case approved by the
         Board of Directors of the Company, provided that such issuances
         are for other than primarily equity financing purposes, and
         provided, further, that the cumulative, aggregate number of shares
         issued in connection with such equipment lease financings and debt
         financings combined does not exceed five percent (5%) of the
         number of shares of Common Stock then outstanding (assuming the
         exercise or conversion into Common Stock of all other securities
         then outstanding that are exercisable for or convertible into
         Common Stock);


                                       -17-

                                       
<PAGE>
 
                      (iii)  Common Stock issued or issuable upon
         conversion of the Series A Preferred Stock;

                       (iv)  Common Stock issued or issuable in connection
         with a merger or consolidation as a result of which the holders of
         the Company's outstanding securities immediately prior to the
         consummation of such transaction hold securities in excess of
         fifty percent (50%) of the voting power of the surviving or
         resulting entity; or

                        (v)  Common Stock issued in a registered public
         offering.

                   (e)  The preemptive right set forth in this Section 2.4
         may not be assigned or transferred, except to a Permitted
         Transferee.

              No holder shall be entitled to exercise any preemptive right
         provided for in this Section 2.4 after the earlier of
         (i) the effective date of a Qualified Public Offering or (ii) such
         date as the Investors, together with any Related Mutual Funds,
         hold fewer than 800,000 shares (adjusted for stock splits, stock
         dividends, combinations, reclassifications and similar events) of
         Series A Preferred Stock (and/or Common Stock issued on conversion
         thereof).

              2.5  Positive Covenants.  So long as any shares of the Series
                   ------------------

         such termination, the Company will promptly thereafter engage
         another firm of independent public accountants of recognized
         national standing.  In its notice to the Investors the Company
         shall state whether the change of accountants was recommended or
         approved by the Board of Directors of the Company or any committee
         thereof.

                   (b)  The Company will cause senior management (except
         for Marlene Krauss, Chairman of the Board) personnel and key
         employees now or hereafter employed by it or any subsidiary to
         enter into a proprietary information and inventions agreement,
         which agreement shall include a provision with respect to

         to include his, her or its Registrable Securities in such
         registration shall be conditioned upon such Holder's participation
         in such underwriting and the inclusion of such Holder's
         Registrable Securities in the underwriting (unless otherwise
         mutually agreed by a majority in interest of the Investors and
         such Holder) to the extent provided herein.  All Holders proposing
         to distribute their securities through such underwriting shall
         (together with the Company as provided in Subsection 1.4(e)) enter
         into an underwriting agreement in customary form with the
         underwriter or underwriters selected for such underwriting.
         Notwithstanding any other provision of this Section 1.2, if the
         underwriter advises the Investors in writing that marketing
         factors require a limitation of the number of shares to be
         underwritten, then the Investors shall so advise all Holders of
         Registrable Securities which would otherwise be underwritten
         pursuant hereto, and the number of shares of Registrable
         Securities that may be included in the underwriting shall be


                                        -3-
<PAGE>
 
         allocated among all Holders thereof, including the Investors and
         the Series A Investors, in proportion (as nearly as practicable)
         to the amount of Registrable Securities of the Company requested
         by each Holder, including the Series A Investors, to be included
         in the underwriting; provided, however, that the number of shares
         of Registrable Securities of the Holders, including the Series A
         Investors, to be included in such underwriting shall not be
         reduced unless all other securities are first entirely excluded
         from the underwriting.

                        (c)  Notwithstanding the foregoing, if the Company
         shall furnish to the Investors a certificate signed by the Chief
         Executive Officer of the Company stating that, in the good faith
         judgment of the Board of Directors of the Company, it would be
         seriously detrimental to the Company and its stockholders for such
         registration statement to be filed and it is therefore essential
         to defer the filing of such registration statement, the Company
         shall have the right to defer taking action with respect to such
         filing for a period of not more than ninety (90) days after
         receipt of the request of the Investors; provided, however, that
         the Company may not utilize this right more than once in any
         twelve (12) month period.

                        (d)  In addition, the Company shall not be
         obligated to effect, or to take any action to effect, any
         registration pursuant to this Section 1.2:

                             (i)  After the Company has effected two (2)
         registrations pursuant to this Section 1.2, excluding any
         registrations effected on Form S-3, and such registrations have
         been declared or ordered effective;

                            (ii)  During the period starting with the date
         sixty (60) days prior to the Company's good faith estimate of the
         date of filing of, and ending on a date one hundred eighty (180)
         days after the effective date of, the first registration statement
         for a public offering subject to Section 1.3 hereof; provided that
         the Company is actively employing in good faith all reasonable
         efforts to cause such registration statement to become effective;

                           (iii)  During the period starting with the date
         sixty (60) days prior to the Company's good faith estimate of the
         date of filing of, and ending on a date ninety (90) days after the
         effective date of, any subsequent registration statement for a
         public offering subject to Section 1.3 hereof; provided that the
         Company is actively employing in good faith all reasonable efforts
         to cause such registration statement to become effective;

<PAGE>
 
                            (iv)  If the Investors propose to dispose of
         shares of Registrable Securities that may be immediately
         registered on Form S-3 pursuant to a request made pursuant to
         Section 1.12 below; or

                             (v)  If the Company delivers to the Investors
         an opinion, in form and substance reasonably acceptable to such
         Investors, of counsel reasonably satisfactory to the Investors,
         that the Registrable Securities requested to be registered by the
         Investors may be sold or transferred pursuant to Rule 144(k) of
         the Act.

                   1.3  Company Registration.  If (but without any
                        --------------------
         obligation to do so) the Company proposes to register (including
         for this purpose a registration effected by the Company for
         stockholders other than the Holders) any of its stock or other
         securities under the Act in connection with the public offering of
         such securities (other than an Excluded Registration, a
         registration on any form which does not include substantially the
         same information as would be required to be included in a
         registration statement covering the sale of the Registrable
         Securities or a registration in which the only Common Stock being
         registered is Common Stock issuable upon conversion of debt
         securities which are also being registered), the Company shall, at
         such time, promptly give each Holder written notice of such
         registration.  Upon the written request of each Holder given
         within twenty (20) days after giving of such notice by the Company
         in accordance with Section 3.5, the Company shall, subject to the
         provisions of Section 1.8, cause to be registered under the Act
         all of the Registrable Securities that each such Holder has
         requested to be registered.  Neither the giving of any notice nor
         the making of any request hereunder shall impose any obligation on
         a Holder to sell any shares.

                   1.4  Obligations of the Company.  Whenever required
                        --------------------------
         under this Section 1 to effect the registration of any Registrable
         Securities, the Company shall, as expeditiously as reasonably
         possible:

                        (a)  Prepare and file with the SEC a registration
         statement with respect to such Registrable Securities and use its
         best efforts to cause such registration statement to become
         effective, and keep such registration statement effective for a
         period of up to one hundred twenty (120) days or until the
         distribution contemplated in the Registration Statement has been
         completed, whichever first occurs; provided, however, that such
         one hundred twenty (120) day period shall be extended for a period
         of time equal to the period the Holder refrains from selling any
         securities included in such registration at the request of an
         underwriter of Common Stock (or other securities) of the Company,
         and provided further that in the case of any registration of


                                        -5-
<PAGE>
 
         Registrable Securities on Form S-3 that are intended to be offered
         on a continuous or delayed basis, such one hundred twenty (120)
         day period shall be extended until all such Registrable Securities
         are sold, if applicable rules under the Act governing the
         obligation to file a post-effective amendment permit, in lieu of
         filing a post-effective amendment which (I) includes any
         prospectus required by Section 10(a)(3) of the Act or
         (II) reflects facts or events representing a material or
         fundamental change in the information set forth in the
         registration statement, the incorporation by reference of
         information required to be included in (I) and (II) above to be
         contained in periodic reports filed pursuant to Section 13 or
         15(d) of the 1934 Act in the registration statement.

                        (b)  Prepare and file with the SEC such amendments
         and supplements to such registration statement and the prospectus
         used in connection with such registration statement as, in the
         opinion of counsel to the Company, may be necessary to comply with
         the provisions of the Act with respect to the disposition of all
         securities covered by such registration statement.

                        (c)  Furnish to the Holders such number of copies
         of a prospectus, including a preliminary prospectus, in conformity
         with the requirements of the Act, and such other documents as they
         may reasonably request in order to facilitate the disposition of
         Registrable Securities owned by them.

                        (d)  Use its best efforts to register and qualify
         the securities covered by such registration statement under such
         other securities or Blue Sky laws of such jurisdictions as shall
         be reasonably requested by the Holders; provided that the Company
         shall not be required in connection therewith or as a condition
         thereto to qualify to do business or to file a general consent to
         service of process in any such states or jurisdictions, unless the
         Company is already subject to service in such jurisdiction and
         except as may be required by the Act.

                        (e)  In the event of any underwritten public
         offering, enter into and perform its obligations under an
         underwriting agreement, in usual and customary form, with the
         managing underwriter of such offering.  Each Holder participating
         in such underwriting shall also enter into and perform its
         obligations under such an agreement.

                        (f)  Notify each Holder of Registrable Securities,
         covered by such registration statement at any time when a
         prospectus relating thereto is required to be delivered under the
         Act, of 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 a material fact required to be stated therein or


                                        -6-
<PAGE>
 
         necessary to make the statements therein not misleading in the
         light of the circumstances then existing.

                        (g)  Cause all such Registrable Securities
         registered pursuant hereunder to be listed on each securities
         exchange on which similar securities issued by the Company are
         then listed.  If no similar securities issued by the Company are
         then listed on an exchange, facilitate the reporting of the
         Registrable Securities on NASDAQ.

                        (h)  Provide a transfer agent and registrar for all
         Registrable Securities registered hereunder and a CUSIP number for
         all such Registrable Securities, in each case not later than the
         effective date of such registration.

                        (i)  Take all other reasonable actions necessary to
         expedite and facilitate disposition by the Investors of the
         Registrable Securities pursuant to the registration statement.

                   1.5  Furnish Information.
                        -------------------
                        (a)  It shall be a condition precedent to the
         obligations of the Company to take any action pursuant to this
         Section 1 with respect to the Registrable Securities of any
         selling Holder that such Holder shall furnish to the Company such
         information regarding itself, the Registrable Securities held by
         it, and the intended method of disposition of such securities as
         shall be required to effect the registration of such Holder's
         Registrable Securities.

                        (b)  The Company shall have no obligation with
         respect to any registration requested pursuant to Section 1.2 or
         Section 1.12 if, due to the operation of Subsection 1.5(a), the
         anticipated aggregate offering price of the Registrable Securities
         to be included in the registration does not equal or exceed the
         anticipated aggregate offering price required to originally
         trigger the Company's obligation to initiate such registration as
         specified in Subsection 1.2(a) or Subsection 1.12(b)(2), whichever
         is applicable.

                   1.6  Expenses of Demand Registration.  All expenses
         other than underwriting discounts and commissions incurred in
         connection with registrations, filings or qualifications pursuant
         to Section 1.2, including (without limitation) all registration,
         filing and qualification fees, printers' and accounting fees, fees
         and disbursements of counsel for the Company and the reasonable
         fees and disbursements of one counsel for the selling Holders
         shall be borne by the Company.

                   1.7  Expenses of Company Registration.  The Company
                        --------------------------------
         shall bear and pay all expenses incurred in connection with any
         registration, filing or qualification of Registrable Securities
         with respect to the registrations pursuant to Section 1.3 for each
         Holder, including (without limitation) all registration, filing,
         and qualification fees, printers' and accounting fees relating or
         apportionable thereto and the reasonable fees and disbursements of
         one counsel for the selling Holders, but excluding underwriting
         discounts and commissions relating to Registrable Securities.

                   1.8  Underwriting Requirements.  In connection with any
                        -------------------------
         offering involving an underwriting of shares of the Company's
         capital stock, the Company shall not be required under Section 1.3
         to include any of a Holder's securities in such underwriting
         unless such Holder accepts the terms of the underwriting as agreed
         upon between the Company and the underwriters selected by it (or
         by other persons entitled to select the underwriters), and then
         only in such quantity as the underwriters determine in their sole
         discretion will not jeopardize the success of the offering by the
         Company.  If the total amount of securities, including Registrable
         Securities, requested by stockholders to be included in such
         offering exceeds the amount of securities sold other than by the
         Company that the underwriters determine in their sole discretion
         is compatible with the success of the offering, then the Company
         shall be required to include in the offering only that number of
         such securities, including Registrable Securities, which the
         underwriters determine in their sole discretion will not
         jeopardize the success of the offering (the securities so included
         to be apportioned pro rata among the selling stockholders
         according to the total amount of securities entitled to be
         included therein owned by each selling stockholder or in such
         other proportions as shall mutually be agreed to by the selling
         stockholders).

                   1.9  Delay of Registration.  No Holder shall have any
                        ---------------------
         right to obtain or seek an injunction restraining or otherwise
         delaying any such registration as the result of any controversy
         that might arise with respect to the interpretation or
         implementation of this Section 1.

                   1.10  Indemnification.  In the event any Registrable
                         ---------------
         Securities are included in a registration statement under this
         Section 1:

                        (a)  To the extent permitted by law, the Company
         will indemnify and hold harmless each Holder, the officers and
         directors of each Holder participating in such registration, any
         underwriter (as defined in the Act) for such Holder and each
         person, if any, who controls such Holder or underwriter within the



                                        -8-
<PAGE>
 
         meaning of the Act or the 1934 Act, against any losses, claims,
         damages, or liabilities (joint or several) to which they may
         become subject under the Act, or the 1934 Act, or otherwise
         insofar as such losses, claims, damages, or liabilities (or
         actions in respect thereof) arise out of or are based upon any of
         the following statements, omissions or violations (collectively a
         "Violation"):  (i) any untrue statement or alleged untrue
         statement of a material fact contained in such registration
         statement, including any preliminary prospectus or final
         prospectus contained therein or any amendments or supplements
         thereto, (ii) the omission or alleged omission to state therein a
         material fact required to be stated therein, or necessary to make
         the statements therein not misleading, or (iii) any violation or
         alleged violation by the Company of the Act, the 1934 Act, or any
         rule or regulation promulgated under the Act, or the 1934 Act, and
         the Company will pay to each such Holder, underwriter or
         controlling person, as incurred, any legal or other expenses
         reasonably incurred by them in connection with investigating or
         defending any such loss, claim, damage, liability, or action;
         provided, however, that the indemnity agreement contained in this
         Subsection 1.10(a) shall not apply to amounts paid in settlement
         of any such loss, claim, damage, liability, or action if such
         settlement is effected without the consent of the Company, which
         consent shall not be unreasonably withheld, nor shall the Company
         be liable in any such case for any such loss, claim, damage,
         liability, or action to the extent that it arises out of or is
         based upon a Violation which occurs in reliance upon and in
         conformity with written information furnished expressly for use in
         connection with such registration by any such Holder, underwriter
         or controlling person.  With respect to any untrue statement or
         alleged untrue statement made in, or omission or alleged omission
         from, any preliminary prospectus or prospectus, the indemnity
         agreement contained in this Subsection 1.10(a) with respect to
         such preliminary prospectus or prospectus, to the extent it is
         based on the claim of a person who purchased any Registrable
         Securities directly from a Holder shall not inure to the benefit
         of such Holder (or to the benefit of any of its officers and
         directors or any person controlling such Holder) if the prospectus
         (or the prospectus as amended or supplemented if the Company shall
         have filed with the Commission any amendment or supplement
         thereto) which shall have been furnished to such Holder by the
         Company in a timely manner and in sufficient quantities, does not
         contain such statement, alleged statement, omission, or alleged
         omission and a copy of the prospectus (or the prospectus as
         amended or supplemented if the Company shall have filed with the
         Commission any amendment or supplement thereto) shall not have
         been sent or given to such person by the Holder (and the Holder
         shall have been obligated so to furnish such a prospectus) and
         such person shall not otherwise have received a copy thereof at or
         prior to the written confirmation of such sale to such person.


                                        -9-
<PAGE>
 
                        (b)  To the extent permitted by law, each selling
         Holder will indemnify and hold harmless the Company, each of its
         directors, each of its officers who has signed the registration
         statement, each person, if any, who controls the Company within
         the meaning of the Act, any underwriter, any other Holder selling
         securities in such registration statement and any controlling
         person of any such underwriter or other Holder, against any
         losses, claims, damages, or liabilities (joint or several) to
         which any of the foregoing persons may become subject, under the
         Act, or the 1934 Act, insofar as such losses, claims, damages, or
         liabilities (or actions in respect thereto) arise out of or are
         based upon any Violation, in each case to the extent (and only to
         the extent) that such Violation occurs in reliance upon and in
         conformity with written information furnished by such Holder
         expressly for use in connection with such registration; and each
         such Holder will pay, as incurred, any legal or other expenses
         reasonably incurred by any person intended to be indemnified
         pursuant to this Subsection 1.10(b), in connection with
         investigating or defending any such loss, claim, damage,
         liability, or action; provided, however, that the indemnity
         agreement contained in this Subsection 1.10(b) shall not apply to
         amounts paid in settlement of any such loss, claim, damage,
         liability or action if such settlement is effected without the
         consent of the Holder, which consent shall not be unreasonably
         withheld; provided, that, in no event shall any selling Holder's
         liability under this Subsection 1.10(b) exceed the proceeds
         received by such Holder from the offering (net of any underwriting
         discounts and commissions).

                        (c)  Promptly after receipt by an indemnified party
         under this Section 1.10 of notice of the commencement of any
         action (including any governmental action), such indemnified party
         will, if a claim in respect thereof is to be made against any
         indemnifying party under this Section 1.10, deliver to the
         indemnifying party a written notice of the commencement thereof
         and the indemnifying party shall have the right to participate in,
         and, to the extent the indemnifying party so desires, jointly with
         any other indemnifying party similarly noticed, to assume the
         defense thereof with counsel mutually satisfactory to the parties;
         provided, however, that an indemnified party (together with all
         other indemnified parties which may be represented without
         conflict by one counsel) shall have the right to retain one
         separate counsel, with the fees and expenses to be paid by the
         indemnifying party, if representation of such indemnified party by
         the counsel retained by the indemnifying party would be
         inappropriate due to actual or potential differing interests
         between such indemnified party and any other party represented by
         such counsel in such proceeding.  The failure to deliver written
         notice to the indemnifying party within a reasonable time of the
         commencement of any such action, if prejudicial to its ability to
         defend such action, shall relieve such indemnifying party of any


                                       -10-
<PAGE>
 
         liability to the indemnified party under this Section 1.10, but
         the omission so to deliver written notice to the indemnifying
         party will not relieve it of any liability that it may have to any
         indemnified party otherwise than under this Section 1.10.

                        (d)  If the indemnification provided for in this
         Section 1.10 is held by a court of competent jurisdiction to be
         unavailable to an indemnified party with respect to any loss,
         liability, claim, damage, or expense referred to therein, then the
         indemnifying party, in lieu of indemnifying such indemnified party
         hereunder, shall contribute to the amount paid or payable by such
         indemnified party as a result of such loss, liability, claim,
         damage, or expense in such proportion as is appropriate to reflect
         the relative fault of the indemnifying party on the one hand and
         of the indemnified party on the other in connection with the
         statements or omissions that resulted in such loss, liability,
         claim, damage, or expense as well as any other relevant equitable
         considerations.  The relative fault of the indemnifying party and
         of the indemnified party shall be determined by reference to,
         among other things, whether the untrue or alleged untrue statement
         of a material fact or the omission to state a material fact
         relates to information supplied by the indemnifying party or by
         the indemnified party and the parties' relative intent, knowledge,
         access to information, and opportunity to correct or prevent such
         statement or omission.

                        (e)  Notwithstanding the foregoing, to the extent
         that the provisions on indemnification and contribution contained
         in the underwriting agreement entered into in connection with the
         underwritten public offering are in conflict with the foregoing
         provisions, the provisions in the underwriting agreement shall
         control.

                        (f)  The obligations of the Company and Holders
         under this Section 1.10 shall survive the completion of any
         offering of Registrable Securities in a registration statement
         under this Section 1, and otherwise.

                   1.11  Reports Under Securities Exchange Act of 1934.
                         ---------------------------------------------
         With a view to making available to the Holders the benefits of
         Rule 144 promulgated under the Act and any other rule or
         regulation of the SEC that may at any time permit a Holder to sell
         securities of the Company to the public without registration or
         pursuant to a registration on Form S-3, the Company agrees to:

                        (a)  make and keep public information available, as
         those terms are understood and defined in SEC Rule 144, at all
         times after ninety (90) days after the effective date of the first
         registration statement filed under the Act by the Company for the
         offering of its securities to the general public;


                                       -11-
<PAGE>
 
                        (b)  take such action, including the voluntary
         registration of its Common Stock under Section 12 of the 1934 Act,
         as is necessary to enable the Holders to utilize Form S-3 for the
         sale of their Registrable Securities, such action to be taken as
         soon as practicable after the end of the fiscal year in which the
         first registration statement filed under the Act by the Company
         for the offering of its securities to the general public is
         declared effective;

                        (c)  file with the SEC in a timely manner all
         reports and other documents required of the Company under the Act
         and the 1934 Act; and

                        (d)  furnish to any Holder, so long as the Holder
         owns any Registrable Securities, forthwith upon request (i) a
         written statement by the Company that it has complied with the
         reporting requirements of SEC Rule 144 (at any time after ninety
         (90) days after the effective date of the first registration
         statement filed by the Company), the Act and the 1934 Act (at any
         time after it has become subject to such reporting requirements),
         (ii) a copy of the most recent annual or quarterly report of the
         Company and such other reports and documents so filed by the
         Company, and (iii) such other information as may be reasonably
         requested in availing any Holder of any rule or regulation of the
         SEC which permits the selling of any such securities without
         registration or pursuant to such form.

                   1.12  Form S-3 Registration.  In case the Company shall
                         ---------------------
         receive, at any time after six months following the completion of
         the first registration statement for a public offering of
         securities of the Company (other than an Excluded Registration), a
         written request from the Investors that the Company effect a
         registration on Form S-3 and any related qualification or
         compliance with respect to all or a part of the Registrable
         Securities owned by such Investors, the Company will:
                        (a)  promptly give written notice of the proposed
         registration, and any related qualification or compliance, to all
         other Holders; and

                        (b)  as soon as practicable, use its best efforts
         to effect such registration and all such qualifications and
         compliances as may be so requested and as would permit or
         facilitate the sale and distribution of all or such portion of
         such Investors' Registrable Securities as are specified in such
         request, together with all or such portion of the Registrable
         Securities of any other Holder or Holders joining in such request
         as are specified in a written request given within twenty (20)
         days after receipt of such written notice from the Company;
         provided, however, that the Company shall not be obligated to
         effect any such registration, qualification or compliance,



                                       -12-
<PAGE>
 
         pursuant to this Section 1.12:  (1) if Form S-3 is not available
         for such offering by the Holders; (2) if the Investors, together
         with the Holders of any other securities of the Company entitled
         to inclusion in such registration, propose to sell Registrable
         Securities and such other securities (if any) at an aggregate
         price to the public (net of any underwriting discounts or
         commissions) of less than $500,000; (3) if the Company shall
         furnish to the Investors a certificate signed by the President of
         the Company stating that, in the good faith judgment of the Board
         of Directors of the Company, it would be seriously detrimental to
         the Company and its shareholders for such Form S-3 registration to
         be effected at such time, in which event the Company shall have
         the right to defer the filing of the Form S-3 registration
         statement for a period of not more than ninety (90) days after
         receipt of the request of the Investors under this Section 1.12;
         provided, however, that the Company shall not utilize this right
         more than once in any twelve (12) month period; (4) if the Company
         has already effected three (3) registrations on Form S-3, or any
         equivalent successor form, for the Holders pursuant to this
         Section 1.12; or (5) in any particular jurisdiction in which the
         Company would be required to qualify to do business or to execute
         a general consent to service of process in effecting such
         registration, qualification or compliance.

                        (c)  Subject to the foregoing, the Company shall
         file a registration statement covering the Registrable Securities
         and other securities so requested to be registered as soon as
         practicable after receipt of the request or requests of the
         Investors.  All expenses incurred in connection with a
         registration requested pursuant to this Section 1.12, including,
         without limitation, all registration, filing, qualification,
         printers' and accounting fees and the reasonable fees and
         disbursements of one (1) counsel for the selling Holders and
         counsel for the Company, but excluding any underwriting discounts
         or commissions associated with Registrable Securities, shall be
         borne by the Company.  Registrations effected pursuant to this
         Section 1.12 shall not be counted as registrations effected
         pursuant to Sections 1.2 or 1.3.

                        (d)  The Company shall not be obligated to effect
         any registration pursuant to this Section 1.12 if the Company
         delivers to the Investors requesting registration under this
         Section 1.12 an opinion, in form and substance acceptable to such
         Investors, of counsel satisfactory to the Investors, that the
         Registrable Securities so requested to be registered may be sold
         or transferred pursuant to Rule 144(k) under the Act.

                   1.13  Assignment of Registration Rights.  The rights to
                         ---------------------------------
         cause the Company to register Registrable Securities pursuant to
         this Section 1 may be assigned (but only with all related
         obligations) by an Investor to:  (i) in the case of an Investor


                                       -13-
<PAGE>
 
         that is an investment company registered under the Investment
         Company Act of 1940, to another such investment company (a
         "Related Mutual Fund") that has the same investment adviser as the
         transferring investment company, without restriction or
         requirement as to number of shares; or (ii) to a transferee or
         assignee of such securities who, as a result of such assignment or
         transfer, acquires at least fifty percent (50%) of such
         transferring Investor's shares of Registrable Securities (in
         either such case, a "Permitted Transferee"), provided:  (a) the
         Company is, within a reasonable time after such transfer,
         furnished with written notice of the name and address of such
         transferee or assignee and the securities with respect to which
         such registration rights are being assigned; (b) such transferee
         or assignee agrees in writing to be bound by and subject to the
         terms and conditions of this Agreement, including without
         limitation the provisions of Section 1.14 below; and (c) such
         assignment shall be effective only if immediately following such
         transfer the further disposition of such securities by the
         transferee or assignee is restricted under the Act.

                   1.14  "Market Stand-Off" Agreement.  Each Investor
                         ----------------------------
         hereby agrees that, during the period of duration specified by the
         Company and an underwriter of Common Stock or other securities of
         the Company, following the effective date of a registration
         statement of the Company filed under the Act, it shall not, to the
         extent requested by the Company and such underwriter, directly or
         indirectly, sell, offer to sell, contract to sell (including,
         without limitation, any short sale), grant any option to purchase
         or otherwise transfer or dispose of (other than to donees who
         agree to be similarly bound) any securities of the Company held by
         it at any time during such period except Common Stock included in
         such registration; provided, however:

                        (a)  that such market stand-off time period shall
         not exceed one hundred eighty (180) days following the effective
         date of the Company's first registration of Common Stock or other
         securities under the Act and ninety (90) days following the
         effective date with respect to all subsequent registrations; and

                        (b)  all officers and directors of the Company and
         all five percent (5%) or greater stockholders of the Company enter
         into similar agreements.

              In order to enforce the foregoing covenant, the Company may
         impose stop-transfer instructions with respect to the Registrable
         Securities of each Investor (and the shares or securities of every
         other person subject to the foregoing restriction) until the end
         of such period.

              Notwithstanding the foregoing, the obligations described in
         this Section 1.14 shall not apply to an Excluded Registration.

                   1.15  Termination of Registration Rights.  No Investor
                         ----------------------------------
         shall be entitled to exercise any right provided for in this
         Section 1 after five (5) years following the effective date of the
         Company's first registration of Common Stock or other securities
         under the Act, other than an Excluded Registration.

              2.   Covenants of the Company.
                   ------------------------

                   2.1  Financial Statements and Other Information.  Except
                        ------------------------------------------
         as otherwise set forth below in this Section 2.1, until the
         Company is subject to the reporting requirements of the 1934 Act,
         the Company will deliver to each of the Investors, for so long as
         such Investor holds any shares of the Company's Series B Preferred
         Stock (or Common Stock issued upon conversion thereof):

                        (a)  as soon as available, but in any event within
         forty-five (45) days after the end of each monthly accounting
         period in each fiscal year (other than the last month in each such
         year), unaudited consolidated statements of operations and
         consolidated cash flows of the Company and its subsidiaries for
         such monthly period and for the period from the beginning of the
         fiscal year to the end of such month, and consolidated balance
         sheets of the Company and its subsidiaries as of the end of such
         monthly period, setting forth in each case comparisons to the
         annual budget and to the corresponding period in the preceding
         fiscal year, and all such statements will be prepared in
         accordance with generally accepted accounting principles,
         consistently applied (except for the absence of notes and subject
         to normal year-end adjustments);

                        (b)  as promptly as possible (but in any event
         within one hundred twenty (120) days) after the end of each fiscal
         year, consolidated statements of operations and a consolidated
         statement of cash flows of the Company and its subsidiaries for
         such fiscal year and consolidated balance sheets and statements of
         stockholders' equity of the Company and its subsidiaries as of the
         end of such fiscal year, setting forth comparisons to the annual
         budget and to the preceding fiscal year, all prepared in
         accordance with generally accepted accounting principles,
         consistently applied, and accompanied by an unqualified opinion
         (except for qualifications regarding specified contingent
         liabilities) of an independent accounting firm selected by the
         Company's Board of Directors;

                        (c)  prior to the end of each fiscal year, an
         annual budget (approved by the Board of Directors) prepared on a


                                       -15-
<PAGE>
 
         monthly, consolidated basis for the Company and its subsidiaries
         for the succeeding fiscal year (displaying detailed anticipated
         statements of operations and cash flows and balance sheets), and
         promptly upon preparation thereof any other significant budgets
         which the Company prepares and any revisions of such annual or
         other budgets;

                        (d)  promptly (and in any event within thirty (30)
         days) after the discovery or receipt of notice of any event or
         circumstance affecting the Company or its subsidiaries that is
         determined in good faith by the Company to be material to the
         Company and its subsidiaries, taken as a whole, including but not
         limited to, the filing of any material litigation against the
         Company or its subsidiaries, acquisitions, mergers, substantial
         sales of assets, significant regulatory action directly affecting
         the Company, the commencement of voluntary or involuntary
         bankruptcy proceedings, natural or other disasters, significant
         changes in management or directors, changes in auditors, and
         execution or termination of, or defaults under, material
         contracts, a letter from the Chief Executive Officer or Chief
         Financial Officer of the Company specifying the nature and period
         of existence thereof and, in the case of material litigation, what
         actions the Company and its subsidiaries have taken and propose to
         take with respect thereto;

                        (e)  promptly after transmission thereof, copies of
         all financial statements, proxy statements, reports and any other
         written communications which the Company sends to its stockholders
         generally and copies of all registration statements and all
         regular, special or periodic reports which it files with the SEC
         or with any securities exchange on which any of its securities are
         then listed, and copies of all press releases and other statements
         made available generally by the Company to the public; and

                        (f)  a notice specifying the terms of all sales of
         the Company's securities, promptly following the consummation
         thereof.

              Each of the financial statements referred to in this
         Section 2.1 will be true and correct in all material respects and
         will fairly present the Company's consolidated financial position
         and results of operations as of the dates and for the periods
         stated therein, subject in the case of the unaudited financial
         statements to changes resulting from normal year-end audit
         adjustments (none of which would, alone or in the aggregate, be
         materially adverse to the Company's financial condition, operating
         results or business prospects).  The Company's obligation to
         provide to the Investors the materials described in Subsection (e)
         above will continue after the Company is subject to the reporting
         requirements of the 1934 Act and until the Investors no longer
         hold any shares of the Company's Series B Preferred Stock (or
         Common Stock issued upon conversion thereof).

                   2.2  Inspection of Property.  Until the Company is
                        ----------------------
         subject to the reporting requirements of the 1934 Act, the Company
         will permit each of the Investors, or any representatives
         designated by an Investor, upon reasonable notice and during
         normal business hours and such other times as an Investor may
         reasonably request, to (i) visit and inspect any of the properties
         of the Company and its subsidiaries, (ii) examine the corporate
         and financial records of the Company and its subsidiaries and make
         copies thereof or extracts therefrom, (iii) discuss the affairs,
         finances and accounts of the Company and its subsidiaries with the
         directors, senior management and independent accountants of the
         Company and its subsidiaries, and (iv) consult with and advise the
         management of the Company and its subsidiaries as to their
         affairs, finances and accounts; provided that such Investor or
         representative shall agree to hold any such copies or extracts in
         confidence and provided further that the Company reserves the
         right to withhold any information and to exclude such Investor or
         such representative from any meeting or portion thereof to the
         extent necessary to preserve attorney-client privilege.

                   2.3  Participation Right.  Subject to the terms and
                        -------------------
         conditions specified in this Section 2.3, the Company hereby
         grants to each Investor a participation right with respect to
         future sales by the Company of its Shares (as hereinafter
         defined).  An Investor shall be entitled to apportion the
         participation right hereby granted it among itself and its
         partners and affiliates and, in the case of an Investor that is a
         registered investment company, among itself and its Related Mutual
         Funds, in such proportions as it deems appropriate.

              Each time the Company proposes to offer any shares of, or
         securities convertible into or exercisable for any shares of, any
         class of its capital stock ("Shares"), the Company shall make an
         offering of such Shares to each Investor in accordance with the
         following provisions:

                        (a)  The Company shall deliver a notice ("Notice")
         to the Investors stating (i) its bona fide intention to offer such
         Shares, (ii) the number of such Shares to be offered, and
         (iii) the price and terms, if any, upon which it proposes to offer
         such Shares.

                        (b)  By written notification received by the
         Company, within twenty (20) calendar days after giving of the
         Notice, the Investor may elect to purchase or obtain, at the price
         and on the terms specified in the Notice, up to that portion of



                                       -17-
<PAGE>
 
         such Shares which equals the proportion that the number of shares
         of Common Stock issued and held, or issuable upon conversion of
         the Series B Preferred Stock then held, by such Investor bears to
         the total number of shares of Common Stock of the Company then
         outstanding (assuming full conversion of all convertible
         securities) ("Pro Rata Share").

                        (c)  If all Shares referred to in the Notice which
         Investors are entitled to obtain pursuant to Subsection 2.3(b) are
         not elected to be obtained as provided in Subsection 2.3(b)
         hereof, the Company may, during the ninety (90) day period
         following the expiration of the period provided in
         Subsection 2.3(b) hereof, offer the remaining unsubscribed portion
         of such Shares to any person or persons at a price not less than,
         and upon terms no more favorable to the offeree than those
         specified in the Notice.  If the Company does not enter into an
         agreement for the sale of the Shares within such period, or if
         such agreement is not consummated within thirty (30) days of the
         execution thereof, the right provided hereunder shall be deemed to
         be revived and such Shares shall not be offered unless first
         reoffered to the Investors in accordance herewith.

                        (d)  The participation right in this Section 2.3
         shall not be applicable to

                             (i)  shares of Common Stock issuable or issued
         to employees, advisors, consultants or outside directors of the
         Company directly or pursuant to a stock option plan or restricted
         stock plan approved by the Board of Directors of the Company so
         long as the cumulative total number of shares of Common Stock so
         issuable and issued (and not repurchased at cost by the Company in
         connection with the termination of employment) does not exceed at
         any time the greater of (i) 3,337,326 shares of Common Stock or
         (ii) twelve percent (12%) of the outstanding shares of Common
         Stock (assuming the exercise or conversion into Common Stock of
         all securities then outstanding that are exercisable for or
         convertible into Common Stock);

                            (ii)  Common Stock issued in connection with
         bona fide research, licensing or corporate partnering
         relationships, in connection with equipment lease financings, or
         upon exercise of warrants issued to institutional lenders in
         connection with non-convertible debt financings, in each case
         approved by the Board of Directors of the Company, provided that
         such issuances are for other than primarily equity financing
         purposes, and provided, further, that the cumulative, aggregate
         number of shares issued in connection with such equipment lease
         financings and debt financings combined does not exceed five
         percent (5%) of the number of shares of Common Stock then
         outstanding (assuming the exercise or conversion into Common Stock
         of all other securities then outstanding that are exercisable for
         or convertible into Common Stock);

                           (iii)  Common Stock issued or issuable upon
         conversion of any class or series of preferred stock;

                            (iv)  Common Stock issued or issuable in
         connection with a merger or consolidation as a result of which the
         holders of the Company's outstanding securities immediately prior
         to the consummation of such transaction hold securities in excess
         of fifty percent (50%) of the voting power of the surviving or
         resulting entity; or

                             (V)  Common Stock issued in a registered
         public offering.

                        (e)  The participation right set forth in this
         Section 2.3 may not be assigned or transferred, except to a
         Permitted Transferee.

              No holder shall be entitled to exercise any participation
         right provided for in this Section 2.3 after the earlier of
         (i) the effective date of a Qualified Public Offering or (ii) such
         date as the Investors, together with any Related Mutual Funds,
         hold fewer than 746,000 shares (adjusted for stock splits, stock
         dividends, combinations, reclassifications and similar events) of
         Series B Preferred Stock (and/or Common Stock issued on conversion
         thereof).

                   2.4  Positive Covenants.  So long as any shares of the
                        ------------------
         Series B Preferred Stock are outstanding, the Company agrees as
         follows:

                        (a)  The Company will retain independent public
         accountants of recognized national standing who shall certify the
         Company's financial statements at the end of each fiscal year.  In
         the event the services of the independent public accountants so
         selected, or any firm of independent public accountants hereafter
         employed by the Company are terminated, the Company will promptly
         thereafter notify the Investors and will request the firm of
         independent public accountants whose services are terminated to
         deliver to the Investors a letter from such firm setting forth the
         reasons for the termination of their services.  In the event of
         such termination, the Company will promptly thereafter engage
         another firm of independent public accountants of recognized
         national standing.  In its notice to the Investors the Company
         shall state whether the change of accountants was recommended or
         approved by the Board of Directors of the Company or any committee
         thereof.

                        (b)  The Company will cause senior management
         (except for Marlene Krauss, Chairman of the Board) personnel and



                                       -19-

         key employees now or hereafter employed by it or any subsidiary to
         enter into a proprietary information and inventions agreement,
         which agreement shall include a provision with respect to
         noncompetition.

                        (c)  The Company shall, promptly following the date
         of this Agreement, obtain, and thereafter maintain in full force
         and effect, fire, casualty, workmen's compensation and liability
         insurance policies, with extended coverage, in such amounts and
         with such coverage as are carried by companies in a position
         similar to that of the Company.

                        (d)  The Company shall use its best efforts to
         maintain (i) a key person life insurance policy in the amount of
         $2.0 million on Dr. Richard J. Cohen, M.D. and (ii) a key person
         life insurance policy in the amount of $1.0 million on Jeffrey M.
         Arnold, with the Company listed as the beneficiary on both
         policies.

                        (e)  The Company's Board of Directors shall meet at
         least once every fiscal quarter.

                        (f)  The Company shall conduct all transactions
         with affiliates on an arm's-length basis; provided, however, that
         nothing contained herein shall be deemed to prohibit the Company
         from performing its obligations under any existing agreements
         between the Company and any of its affiliates as in effect on the
         date hereof but not any supplements, amendments, modifications,
         waivers, renewals or extensions thereof.

                        (g)  The Company shall exercise in full its
         purchase rights under the Restricted Stock Agreement dated of even
         date herewith between the Company and Dr. Richard J. Cohen, M.D.
         (the "Restricted Stock Agreement") and shall refrain from
         amending, altering or agreeing to waive any of its purchase rights
         under the Restricted Stock Agreement.  The Company shall comply in
         all material respects with its obligations under the Consulting
         and Technology Agreement dated as of February 8, 1993 between the
         Company and Dr. Cohen.

                   2.5  Termination of Certain Covenants.  The covenants
                        --------------------------------
         set forth in Section 2.4 shall terminate and be of no further
         force or effect upon the consummation of a Qualified Public
         Offering.

                   2.6  Public Offerings.  The Company hereby covenants and
                        ----------------
         agrees that, without the prior written consent of the Investors,
         prior to January 1, 1996, the Company will not register any shares
         of its capital stock under the Act in connection with a public
         offering of such securities.

         other terms set forth below, to purchase from CAMBRIDGE HEART,
         INC., a Delaware corporation (the "Company"), 219,269 shares of
         fully paid and nonassessable shares of the Company's $.001 par
         value Common Stock (the "Stock") at $1.00 per share of Stock (the
         "Stock Purchase Price") at any time on or after September 24, 1993
         (the "Commencement Date") but not later than 5:00 p.m. (New York
         Time) on September 24, 1998 (the "Expiration Date"), upon
         surrender to the Company at its principal office, Corporate
         Place 1, 99 South Bedford Street, Suite 204, Burlington, MA 01803,
         Attention:  Chief Executive Officer (or at such other location as
         the Company may advise Holder in writing) of this Warrant properly
         endorsed with the form of Subscription Agreement attached hereto
         duly filled in and signed and, unless the Conversion Right set
         forth in Section 1.2 is exercised, upon payment in cash or
         cashier's check of the aggregate Stock Purchase Price for the
         number of shares of Stock for which this Warrant is being
         exercised determined in accordance with the provisions hereof.

              The Stock Purchase Price and, in some cases, the number of
         shares of Stock purchasable hereunder are subject to adjustment as
         provided in Section 3 of this Warrant.  This Warrant and all
         rights hereunder, to the extent not exercised in the manner set
         forth herein shall terminate and become null and void on the
         Expiration Date.

              This Warrant is subject to the following terms and
         conditions:

              1.   Exercise; Issuance of Certificates; Payment for Shares;
                   -------------------------------------------------------
                   Conversion Right.
                   ----------------
                   1.1  Duration of Exercise of Warrant.  This Warrant is
                        -------------------------------
         exercisable at the option of the Holder at any time or from time
         to time but not earlier than on the Commencement Date or later
         than 5:00 p.m. (New York Time) on the Expiration Date for all or 
         portion of the shares of Stock which may be purchased hereunder.
         The Company agrees that the shares of Stock purchased under this
         Warrant shall be and are deemed to be issued to Holder as the
         record owner of such shares as of the close of business on the
         date on which this Warrant shall have been surrendered and payment
         made for such shares.  Subject to the provisions of Section 2,
         certificates for the shares of Stock so purchased, together with
         any other securities or property to which Holder is entitled upon
<PAGE>
 
         such exercise, shall be delivered to Holder by the Company's
         transfer agent at the Company's expense within a reasonable time
         after the rights represented by this Warrant have been exercised.
         Each stock certificate so delivered shall be in such denominations
         of Stock as may be requested by Holder and shall be registered in
         the name of Holder or such other name as shall be designated by
         Holder, subject to the limitations contained in Section 2.  If,
         upon exercise of this Warrant, fewer than all of the shares of
         Stock evidenced by this Warrant are purchased prior to the
         Expiration Date of this Warrant, one or more new warrants
         substantially in the form of, and on the terms in, this Warrant
         will be issued for the remaining number of shares of Stock not
         purchased upon exercise of this Warrant.

                   1.2  Conversion Right.  In lieu of the payment of the
                        ----------------
         Stock Purchase Price, the Holder shall have the right (but not the
         obligation), to require the Company to convert this Warrant, in
         whole or in part, into shares of Stock (the "Conversion Right") as
         provided for in this Section 1.2.  Upon exercise of the Conversion
         Right, the Company shall deliver to the Holder (without payment by
         the Holder of any of the Stock Purchase Price) that number of
         shares of Stock equal to the quotient obtained by dividing (x) the
         value of the Warrant at the time the Conversion Right is exercised
         (determined by subtracting the aggregate Stock Purchase Price in
         effect immediately prior to the exercise of the Conversion Right
         from the aggregate Market Price (as hereinafter defined) for the
         shares of Stock issuable upon exercise of the Warrant immediately
         prior to the exercise of the Conversion Right) by (y) the Market
         Price of one share of Stock immediately prior to the exercise of
         the Conversion Right.  "Market Price" shall mean the Stock Price
         (as defined below) obtained by taking the average over a period of
         thirty consecutive trading days ending on the second trading day
         prior to the date of determination.  As used in this paragraph,
         the term Stock Price shall mean (A) the mean, on each such trading
         day, between the high and low sale price of a share of Stock or if
         no such sale takes place on any such trading day, the mean of the
         closing bid and lowest closing asked prices therefor on any such
         trading day, in each case as officially reported on all national
         securities exchanges on which the Stock is then listed or admitted
         to trading, or (B) if the Stock is not then listed or admitted to
         trading on any national securities exchange, the closing price of
         the Stock on such date, or (C) if no closing price is available on
         any such trading day, the mean between the highest and lowest
         closing bid prices thereof on any such trading date, in the
         over-the-counter market as reported by NASDAQ, (D) if the Stock is
         not then quoted in such system, the mean between the highest and
         lowest bid prices reported by the market makers and dealers for
         the Stock listed as such by the National Quotation Bureau,
         Incorporated or any similar successor organization, or (E) the
         higher of the last bona fide sale made by the Company and the fair
         market value of the Stock as determined by the Board of Directors
         in its good faith judgment.

                   1.3  Exercise of Conversion Right.  The conversion
                        ----------------------------
         rights provided under Section 1.2 hereof may be exercised in whole
         or in part and at any time and from time to time while any
         Warrants remain outstanding.  In order to exercise the conversion
         privilege, the Holder shall surrender to the Company, at its
         offices, this Warrant certificate accompanied by a duly completed
         Notice of Conversion in the form attached hereto as Exhibit A.
         The presentation and surrender shall be deemed a waiver of the
         Holder's obligation to pay all or any portion of the aggregate
         purchase price payable for the shares of Stock issuable upon


                                        -2-
<PAGE>
 
         exercise of this Warrant.  This Warrant certificate (or so much
         thereof as shall have been surrendered for conversion) shall be
         deemed to have been converted immediately prior to the close of
         business on the day of surrender of such Warrant certificate for
         conversion in accordance with the foregoing provisions.  As
         promptly as practicable on or after the conversion date, the
         Company shall issue and shall deliver to the Holder (i) a
         certificate or certificates representing the largest number of
         whole shares of Stock to which the Holder shall be entitled as a
         result of the conversion, and (ii) if the Warrant certificate is
         being converted in part only, a new certificate in principal
         amount equal to the unconverted portion of the Warrant
         certificate.  If this Warrant is executed in whole, in lieu of any
         fractional shares of Stock to which the Holder shall be entitled,
         the Company shall pay to the Holder cash in accordance with the
         provisions of Section 12 hereof.

              2.   Shares to Be Fully Paid; Reservation of Shares.  The
                   ----------------------------------------------
         Company covenants and agrees that all shares of Stock which may be
         issued upon the exercise of this Warrant (the "Warrant Shares")
         and all shares of common stock issuable upon conversion of the
         Warrants (the "Conversion Shares") will, upon issuance, be duly
         authorized, validly issued, fully paid and nonassessable and free
         from all preemptive rights of any stockholder and free of all
         taxes, liens and charges with respect to the issue thereof.  The
         Company covenants that it will reserve and keep available a
         sufficient number of shares of its authorized but unissued Stock
         for such exercise and/or conversion, as the case may be.  The
         Company will take all such reasonable action as may be necessary
         to assure that such shares of Stock may be issued as provided
         herein without violation of any applicable law or regulation, or
         of any requirements of any domestic securities exchange or
         automated quotation system upon which the Stock may be listed.

              3.   Adjustment of Stock Purchase Price and Number of Shares.
                   -------------------------------------------------------
         The Stock Purchase Price and, in some cases, the number of shares
         purchasable upon the exercise of this Warrant shall be subject to
         adjustment from time to time upon the occurrence of certain events
         described in this Section 3.

                   3.1  Subdivision or Combination of Stock and Stock
                        ---------------------------------------------
         Dividend.  In case the Company shall at any time subdivide its
         --------
         outstanding shares of Stock into a greater number of shares or
         declare a dividend upon its Stock payable solely in shares of
         Stock, the Stock Purchase Price in effect immediately prior to
         such subdivision or declaration shall be proportionately reduced,
         and the number of shares issuable upon exercise of the Warrant
         shall be proportionately increased.  Conversely, in case the
         outstanding shares of Stock of the Company shall be combined into
         a smaller number of shares, the Stock Purchase Price in effect
         immediately prior to such combination shall be proportionately
         increased, and the number of shares issuable upon exercise of the
         Warrant shall be proportionately reduced.

                   3.2  Intentionally Omitted.

                   3.3  Notice of Adjustment.  Promptly after adjustment of
                        --------------------
         the Stock Purchase Price or any increase or decrease in the number
         of shares purchasable upon the exercise of this Warrant, the
         Company shall give written notice thereof, by first class mail,
         postage prepaid, addressed to the registered holder of this
         Warrant at the address of such holder as shown on the books of the
         Company.  The notice shall be signed by the Company's chief
         

                                        -3-
<PAGE>
 
         financial officer and shall state the effective date of the
         adjustment and the Stock Purchase Price resulting from such
         adjustment and the increase or decrease, if any, in the number of
         shares purchasable at such price upon the exercise of this
         Warrant, setting forth in reasonable detail the method of
         calculation and the facts upon which such calculation is based.

                   3.4  Other Notices.  If at any time:
                        -------------
                        (a)  the Company shall declare any cash dividend
         upon its Stock;

                        (b)  the Company shall declare any dividend upon
         its Stock payable in stock (other than a dividend payable solely
         in shares of Stock) or make any special dividend or other
         distribution to the holders of its Stock;
                        (c)  there shall be any consolidation or merger of
         the Company with another corporation, or a sale of all or
         substantially all of the Company's assets to another corporation;
         or

                        (d)  there shall be a voluntary or involuntary
         dissolution, liquidation or winding-up of the Company;

         then, in any one or more of said cases, the Company shall give, by
         certified or registered mail, postage prepaid, addressed to the
         registered holder of this Warrant at the address of such holder as
         shown on the books of the Company, (i) at least 30 days' prior
         written notice of the date on which the books of the Company shall
         close or a record shall be taken for such dividend, distribution
         or subscription rights or for determining rights to vote in
         respect of any such dissolution, liquidation or winding-up; (ii)
         at least 10 days' prior written notice of the date on which the

         merger, sale, dissolution, liquidation or winding-up, at least 30
         days' written notice of the date when the same shall take place.
         Any notice given in accordance with clause (i) above shall also
         specify, in the case of any such dividend, distribution or option
         rights, the date on which the holders of Stock shall be entitled
         thereto.  Any notice given in accordance with clause (iii) above
         shall also specify the date on which the holders of Stock shall be
         entitled to exchange their Stock for securities or other property
         deliverable upon such reorganization, reclassification,
         consolidation, merger, sale, dissolution, liquidation or
         winding-up, as the case may be.  If the Holder of the Warrant does
         not exercise this Warrant prior to the occurrence of an event
         described above, except as provided in Sections 3.1 and 3.5, the
         Holder shall not be entitled to receive the benefits accruing to
         existing holders of the Stock in such event.

                   3.5  Changes in Stock.  In case at any time following
                        ----------------
         the date hereof, the Company shall be a party to any transaction
         (including, without limitation, a merger, consolidation, sale of
         all or substantially all of the Company's assets or
         recapitalization of the Stock) in which the previously outstanding
         Stock shall be changed into or exchanged for different securities
         of the Company or common stock or other securities of another
         corporation or interests in a noncorporate entity or other
         property (including cash) or any combination of any of the

                                      -4-
<PAGE>
 
         foregoing (each such transaction being herein called the
         "Transaction" and the date of consummation of the Transaction
         being herein called the "Consummation Date"), then, as a condition
         of the consummation of the Transaction, lawful and adequate 
         provisions shall be made so that each Holder, upon the exercise
         hereof at any time on or after the Consummation Date, shall be
         entitled to receive; and this Warrant shall thereafter represent
         the right to receive, in lieu of the Stock issuable upon such
         exercise prior to the Consummation Date, the highest amount of
         securities or other property to which such Holder would actually
         have been entitled as a stockholder upon the consummation of the
         Transaction if such Holder had exercised such Warrant immediately
         prior thereto.  The provisions of this Section 3.5 shall similarly
         apply to successive Transactions.

              4.   Issue Tax.  The issuance of certificates for shares of
                   ---------        
         Stock upon the exercise of the Warrant shall be made without
         charge to the holder of the Warrant for any issue tax in respect
         thereof; provided, however, that the Company shall not be required
         to pay any tax which may be payable in respect of any transfer
         involved in the issuance and delivery of any certificate in a name
         other than that of the then holder of the Warrant being exercised.

              5.   No Voting or Dividend Rights; Limitation of Liability.
                   -----------------------------------------------------  
         Nothing contained in this Warrant shall be construed as conferring
         upon the holder hereof the right to vote or to consent or to
         receive notice as a stockholder in respect of meetings of
         stockholders for the election of directors of the Company or any
         other matters or any rights whatsoever as a stockholder of the
         Company.  Except for the adjustment to the Stock Purchase Price
         pursuant to Section 3.1 in the event of a dividend on the Stock
         payable in shares of Stock, no dividends or interest shall be
         payable or accrued in respect of this Warrant or the interest
         represented hereby or the shares purchasable hereunder until, and
         only to the extent that, this Warrant shall have been exercised.
         No provisions hereof, in the absence of affirmative action by the
         holder to purchase shares of Stock, and no mere enumeration herein
         of the rights or privileges of the holder hereof, shall give rise
         to any liability of such holder for the Stock Purchase Price or as
         a stockholder of the Company whether such liability is asserted by
         the Company or by its creditors.

              6.   Restrictions on Transferability of Securities;
                   ---------------------------------------------

         Securities in writing that it has determined that such Registrable
         Securities may be sold pursuant to Rule 144 (or any successor
         provision) without restriction under Rule 144(e) thereof, and,
         based upon such determination, the legend shall have been removed.

                   7.2  Company Registration.  If (but without any
                        --------------------
         obligation to do so) the Company proposes to Register at any time
         prior to the Restriction Termination Date (including for this
         purpose a Registration effected by the Company for stockholders
         other than the Holder) any of its stock or other securities under
         the Act in connection with the underwritten public offering of
         such securities solely for cash (other than a Registration of
         securities in connection with mergers, acquisitions, exchange
         offers, distributions to the Company's stockholders, or stock
         option or other employee benefit plans or a Registration in any
         form which does not include substantially the same information as
         would be required to be included in a registration statement
         covering the sale of the Registrable Securities), the Company
         shall, at each such time, promptly give Holder written notice of
         such Registration.  Upon the written request of Holder given
         within 15 days after mailing of such notice by the Company, the
         Company shall, subject to the following provisions, use all
         reasonable efforts to cause to be included in such Registration
         all of the Registrable Securities that Holder has requested to be
         included.

              The Company shall not be required under this Section 7.2 to
         include any of the Holder's securities in an underwritten offering
         of the Company's securities unless such Holder accepts the terms
         of the underwriting as agreed upon between the Company and the
         underwriters selected by it, and then only in such quantity as
         will not, in the opinion of the managing underwriters, interfere
         with the successful marketing of the offering by the Company.

              Notwithstanding the foregoing, the Company shall have no
         obligation to comply with the foregoing provisions of this Section
         7.2 if, in the opinion of counsel to the Company reasonably
         acceptable to the person or persons from whom such written request
         has been received, registration under the Securities Act is not
         required for the transfer of the Registrable Securities in the
         amount and manner proposed by such person or persons.

              7.3  Blue Sky.  In the event of any Registration pursuant to
                   --------
         this Section 7, the Company will exercise its best efforts to
         Register and qualify the Registrable Securities covered by the
         Registration Statement under such other securities or Blue Sky
         laws of such jurisdictions as shall be reasonably requested by the
         Holders for the distribution of such securities; provided,
         however, that the Company shall not be required to qualify to do
         business, to file a general consent to service of process or to
         subject itself to taxation in any state or jurisdiction in which
         it is not now qualified.  The Company will furnish to the Holder
         written advice of its counsel with respect to registration or
         exemption of such Registrable Securities in such jurisdictions.

                   7.4  Expenses of Registration.  All Registration
                        ------------------------
         Expenses incurred in connection with a Registration pursuant to
         Section 7.2 shall be borne by the Company.  All Selling Expenses
         shall be borne by the Holder.

                   7.5  Registration Procedures.
                        -----------------------

                        7.5.1  Advice by Company.  The Company will keep
                               -----------------
         the Holder advised as to the initiation and completion of such
         Registration.  At its expense the Company will (i) use its best
         efforts to keep such Registration effective until the earlier of
         the date on which the Holder has completed the distribution
         described in the Registration Statement or the Restriction

                                      -7-
<PAGE>
 
         Termination Date with respect to such Securities; and (ii) furnish
         such number of prospectuses (including preliminary prospectuses)
         and other documents as the Holder from time to time may reasonably
         request.

                        7.5.2  Amendments.  The Company will promptly
                               ----------
         prepare and file with the Commission such amendments and
         prospectus supplements, including post-effective amendments, to
         the Registration Statement as the Company determines may be
         necessary or appropriate, and use its best efforts to have such
         post-effective amendments declared effective as promptly as
         practicable; cause the related prospectus to be supplemented by
         any prospectus supplement, and as so supplemented, to be filed
         with the Commission; and notify the Holder of any securities
         included in such Registration Statement and the underwriter
         thereof, if any, promptly when a prospectus, any prospectus
         supplement or post-effective amendment must be filed or has been
         filed and, with respect to any post-effective amendment, when the
         same has become effective.

                   7.5.3  Underwritten Offerings.  At the request of the
                          ----------------------
         Holder requesting Registration of Registrable Securities pursuant
         to this Section 7, on the date that such Registrable Securities
         are delivered to the underwriters for sale pursuant to such
         Registration in an underwritten offering pursuant to Section 7.2,
         the Company will (a) furnish (i) an opinion, dated as of such
         date, of the independent counsel representing the Company for the
         purposes of such Registration, addressed to the underwriter, in a
         customary form and covering matters of the type customarily
         covered in such legal opinions; and (ii) a comfort letter dated as
         of such date, from the independent certified public accountants of
         the Company addressed to the underwriter in a customary form and
         covering matters of the type customarily covered by such comfort
         letters; such opinion of counsel shall additionally cover such
         other legal matters with respect to the Registration in respect of
         which such opinion is being given as such underwriter may
         reasonably request and such letter from the independent certified
         public accountants shall additionally cover such other financial
         matters (including information as to the period ending not more
         than five business days prior to the date of such letter) with
         respect to the Registration in respect of which such letter is
         being given as such underwriter may reasonably request; and (b)
         with such Holder, enter into customary agreements (including an
         underwriting agreement in customary form) and take such other
         actions as are reasonably required in order to expedite or
         facilitate the disposition of such Registrable Securities.

                   7.6  Information Furnished by Holder.  It shall be a
                        -------------------------------
         condition precedent to the Company's obligations under this
         Agreement that the Holder furnish to the Company in writing such
         information regarding such Holder and the distribution proposed by
         such Holder as the Company may reasonably request.

                   7.7  Indemnification.
                        ---------------

                        7.7.1  Company's Indemnification of Holder.  The
                               -----------------------------------
         Company will indemnify Holder, each of its officers, directors and
         partners, and each person controlling such Holder, with respect to
         which Registration, qualification or compliance of Registrable
         Securities has been effected pursuant to this Agreement, and each
         underwriter, if any, and each of its officers, directors,
         constituent partners, and each person who controls any underwriter
         against all claims, losses, damages or liabilities (or actions in

                                        -8-
<PAGE>
 
         respect thereof) to the extent such claims, losses, damages or
         liabilities arise out of or are based upon any untrue statement
         (or alleged untrue statement) of a material fact contained in any
         prospectus or any related Registration Statement incident to any
         such Registration, qualification or compliance, 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, or any violation by the Company of any rule or
         regulation promulgated under the Securities Act applicable to the
         Company and relating to action or inaction required of the Company
         in connection with any such Registration; and the Company will
         reimburse Holder, each such underwriter and each person who
         controls such Holder or underwriter, for any legal and any other
         expenses reasonably incurred in connection with investigating or
         defending any such claim, loss, damage, liability or action;
         provided, however, that the indemnity contained in this Section
         7.7.1 shall not apply to amounts paid in settlement of any such
         claim, loss, damage, liability or action if settlement is effected
         without the consent of the Company (which consent shall not
         unreasonably be withheld or delayed); and provided, further, that
         the Company will not be liable in any such case to the extent that
         any such claim, loss, damage, liability or expense arises out of
         or is based upon any untrue statement or omission based upon
         written information furnished to the Company by Holder,
         underwriter or controlling person for use in connection with the
         offering of securities of the Company.  Notwithstanding the above,
         the foregoing indemnity agreement is subject to the condition
         that, insofar as it relates to any such untrue statement; alleged
         untrue statement, omission or alleged omission made in a
         preliminary prospectus, such indemnity agreement shall not inure
         to the benefit of any underwriter or Holder, if there is no
         underwriter, if a copy of the final prospectus was not furnished
         to the person asserting the loss, liability, claim or damage at or
         prior to the time such action is required by the Securities Act if
         the final prospectus corrected the untrue statement or omission or
         alleged untrue statement or omission.

                        7.7.2  Holders' Indemnification of Company.  Holder
                               -----------------------------------
         will, if Registrable Securities held by Holder are included in the
         Securities as to which a Registration is being effected pursuant
         to this Agreement, indemnify the Company, each of its directors
         and officers, each underwriter, if any, of the Company's
         securities covered by such a Registration Statement, each person
         who controls the Company or such underwriter within the meaning of
         the Securities Act, against all claims, losses, damages and
         liabilities (or actions in respect thereof) arising out of or
         based upon any untrue statement (or alleged untrue statement) of a
         material fact contained in any such Registration Statement or
         related prospectus, 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; and will reimburse
         the Company, such directors, officers, partners, persons,
         underwriters or control persons for any legal and any other
         expenses reasonably incurred in connection with investigating or
         defending any such claim, loss, damage, liability or action, in
         each case to the extent, but only to the extent, that such untrue
         statement (or alleged untrue statement) or omission (or alleged
         omission) is made in such Registration Statement or prospectus in
         reliance upon and in conformity with written information furnished
         to the Company by Holder and stated to be specifically for use in
         connection with the offering of Securities of the Company.

                        7.7.3  Indemnification Procedure.  Promptly after
                               -------------------------
         receipt by an indemnified party under this Section 7.7 of notice
         of the commencement of any action, such indemnified party will, if
         a claim in respect thereof is to be made against an indemnifying
         party under this Section 7.7, notify the indemnifying party in
         writing of the commencement thereof and generally summarize such
         action.  The indemnifying party shall have the right to
         participate in and to assume the defense of such claim, and shall
         be entitled to select counsel for the defense of such claim with
         the approval of any parties entitled to indemnification, which
         approval shall not be unreasonably withheld.  Notwithstanding the
         foregoing, the parties entitled to indemnification shall have the
         right to employ separate counsel (reasonably satisfactory to the
         indemnifying party) to participate in the defense thereof, but the
         fees and expenses of such counsel shall be the expense of such
         indemnified parties unless the named parties to such action or
         proceedings include both the indemnifying party and the
         indemnified parties and the indemnifying party or such indemnified
         parties shall have been advised by counsel that there are one or
         more legal defenses available to it which are different from or
         additional to those available to the indemnifying party (in which
         case, if the indemnified party notifies the indemnifying party in
         writing that it elects to employ separate counsel at the
         reasonable expense of the indemnifying party, the indemnifying
         party shall not have the right to assume the defense of such
         action or proceeding on behalf of the indemnified party, as the
         case may be, it being understood, however, that the indemnifying
         party shall not, in connection with any such action or proceeding
         or separate or substantially similar or related action or
         proceeding in the same jurisdiction arising out of the same
         general allegations or circumstances, be liable for the reasonable
         fees and expenses of more than one separate counsel at any time
         for the indemnifying party and all indemnified parties, which
         counsel shall be designated in writing by the Holders of a
         majority of the Registrable Securities).  If the indemnifying
         party withholds consent to a settlement or proposed settlement by
         the indemnified party, it shall acknowledge to the indemnified
         party its indemnification obligations hereunder.

                        7.7.4  Contribution.  If the indemnification
                               ------------
         provided for in this Section 7.7 from an indemnifying party is
         unavailable to an indemnified party hereunder in respect to any
         losses, claims, damages, liabilities or expenses referred to
         herein, then the indemnifying party, in lieu of indemnifying such
         indemnified party, shall contribute to the amount paid or payable
         by such indemnified party as a result of such losses, claims,
         damages, liabilities or expenses in such proportion as is
         appropriate to reflect the relative fault of the indemnifying
         party and indemnified party in connection with the statements or
         omissions which result in such losses, claims, damages,
         liabilities or expenses, as well as any other relevant equitable
         considerations.  The relative fault of such indemnifying party and
         indemnified party shall be determined by reference to, among other
         things, whether the untrue or alleged untrue statement of a
         material fact or the omission or alleged omission to state a
         material fact relates to information supplied by such indemnifying
         party or indemnified party and the parties' relative intent,
         knowledge, access to information supplied by such indemnifying
         party or indemnified party and opportunity to correct or prevent
         such statement or omission.  The amount paid or payable by a party
         as a result of the losses, claims, damages, liabilities and
         expenses referred to above shall deemed to include any legal or
         other fees or expenses reasonably incurred by such party in          

                                     -10-

         connection with investigating or defending any action, suit,
         proceeding or claim.

                   7.8  Transfer of Rights.  As defined herein, the term
                        ------------------
         Transfer shall mean any sale, hypothecation, transfer or other
         disposition of Registrable Securities or any interest therein
         other than a sale registered under a Registration Statement.  The
         right to cause the Company to Register Registrable Securities
         granted by the Company to Holder under this Section 7 may be
         assigned by Holder.

                   7.9  No-Action Letter or Opinion of Counsel in Lieu of
                        -------------------------------------------------
         Registration.  Notwithstanding anything else in this Agreement, if
         ------------
         the Company shall have obtained from the Commission a "no-action"
         letter in which the Commission has indicated that it will take no
         action if, without Registration under the Securities Act, the
         Holder disposes of Registrable Securities covered by any request
         for Registration made under this Section in the specific manner in
         which the Holder proposes to dispose of the Registrable Securities
         included in such request (including, without limitation, inclusion
         of such Registrable Securities in an underwriting initiated by
         either the Company or the Holder), or if in the opinion of counsel
         for the Company concurred in by counsel for the Holder, which
         concurrence shall not be unreasonably withheld, no Registration
         under the Securities Act is required in connection wit such
         disposition, the Registrable Securities included in such request
         shall not be eligible for Registration under this Agreement;
         provided, however, that any Registrable Securities not so disposed
         of shall be eligible for Registration in accordance with the terms
         of this Agreement with respect to other proposed dispositions to
         which this Section 7.9 does not apply.  In addition, the
         obligation of the Company to file or maintain the effectiveness of
         any Registration Statement under this Section 7 shall be suspended
         with respect to any Securities held by the Holder at any time
         following the Restriction Termination Date with respect to such
         Securities.

              8.   Modification and Waiver.  This Warrant and any provision
                   -----------------------
         hereof may be changed, waived, discharged or terminated only by an
         instrument in writing signed by the party against which
         enforcement of the same is sought.

              9.   Notices.  Any notice, request or other document required
                   -------
         or permitted to be given or delivered to the holder hereof or the
         Company shall be delivered or shall be sent by certified or
         registered mail, postage prepaid, to each such holder at its
         address as shown on the books of the Company or to the Company at
         the address indicated therefor in the first paragraph of this
         Warrant.

              10.  Descriptive Headings and Governing Law.  The descriptive
                   --------------------------------------
         headings of the several sections and paragraphs of this Warrant
         are inserted for convenience only and do not constitute a part of
         this Warrant.  This Warrant shall be construed and enforced in
         accordance with, and the rights of the parties shall be governed
         by, the laws of the State of New York.

              11.  Lost Warrants or Stock Certificates.  The Company
                   -----------------------------------
         represents and warrants to Holder that upon receipt of evidence
         reasonably satisfactory to the Company of the loss, theft,
         destruction or mutilation of any Warrant or stock certificate and,
         in the case of any such loss, theft or destruction, upon receipt

                                     -11-
<PAGE>
 
         of an indemnity and, if requested, bond reasonably satisfactory to
         the Company, or in the case of any such mutilation, upon surrender
         and cancellation of such Warrant or stock certificate, the Company
         at its expense will make and deliver a new Warrant or stock
         certificate, of like tenor, in lieu of the lost, stolen, destroyed
         or mutilated Warrant or stock certificate.

              12.  Fractional Shares.  No fractional shares shall be issued
                   -----------------
         upon exercise of this Warrant.  The Company shall, in lieu of
         issuing any fractional share pay the holder entitled to such
         fraction a sum in cash equal to the fair market value of any such
         fractional interest as it shall appear on the public market, or if
         there is no public market for such shares, then as shall be
         reasonably determined by the Company.

              IN WITNESS WHEREOF, the Company has caused this Warrant to be
         executed by its officer, thereunto duly authorized as of the 29th
         day of December, 1993.

         below), upon surrender to the Company at its principal office,
         645 Madison Avenue, New York, New York 10022, Attention:  Chief
         Executive Officer (or at such other location as the Company may

         the form of Subscription Agreement attached hereto duly filled in
         and signed and, unless the Conversion Right set forth in
         Section 1.2 is exercised, upon payment in cash or cashier's check
         of the aggregate Stock Purchase Price for the number of shares for
         which this Warrant is being exercised determined in accordance
         with the provisions hereof.  The Stock Purchase Price and, in some
         cases, the number of shares purchasable hereunder are subject to
         adjustment as provided in Section 3 of this Warrant.  This Warrant
         and all rights hereunder, to the extent not exercised in the
         manner set forth herein shall terminate and become null and void
         on the Expiration Date.  "Expiration Date" means the fifth
         anniversary of the Commencement Date.  This Warrant is issued
         pursuant to Section 4(b) of the Sales Agency Agreement, dated as
         of May 3, 1993, as amended, among the Company and KBL Healthcare,
         Inc. (the "Sales Agency Agreement") relating to the offering of a
         minimum of 3,000,000 and a maximum of 6,000,000 shares of Stock.

              This Warrant is subject to the following terms and
         conditions:

              1.   Exercise; Issuance of Certificates; Payment for Shares;
                   ------------------------------------------------------
                   Conversion Right.
                   ----------------

                   1.1  Duration of Exercise of Warrant.  This Warrant is
                        -------------------------------
         exercisable at the option of the Holder at any time or from time
         to time but not earlier than on the Commencement Date or later
         than 5:00 p.m. (New York Time) on the Expiration Date for all or a
         portion of the shares of Stock which may be purchased hereunder.
         The Company agrees that the shares of Stock purchased under this
         Warrant shall be and are deemed to be issued to Holder as the
         record owner of such shares as of the close of business on the
         date on which this Warrant shall have been surrendered and payment
         made for such shares.  Subject to the provisions of Section 2,
         certificates for the shares of Stock so purchased, together with
         any other securities or property to which Holder is entitled upon
         such exercise, shall be delivered to Holder by the Company's
         transfer agent at the Company's expense within a reasonable time
         after the rights represented by this Warrant have been exercised.
         Each stock certificate so delivered shall be in such denominations

         the name of Holder or such other name as shall be designated by

         upon exercise of this Warrant, fewer than all of the shares of
         Stock evidenced by this Warrant are purchased prior to the
         Expiration Date of this Warrant, one or more new warrants
         substantially in the form of, and on the terms in, this Warrant
         will be issued for the remaining number of shares of Stock not
         purchased upon exercise of this Warrant.

                   1.2  Conversion Right.  In lieu of the payment of the
                        ----------------
         Stock Purchase Price, the Holder shall have the right (but not the
         obligation), to require the Company to convert this Warrant, in
         whole or in part, into shares of Stock (the "Conversion Right") as
         provided for in this Section 1.2.  Upon exercise of the Conversion
         Right, the Company shall deliver to the Holder (without payment by
         the Holder of any of the Stock Purchase Price) that number of
         shares of Stock equal to the quotient obtained by dividing (x) the
         value of the Warrant at the time the Conversion Right is exercised
         (determined by subtracting the aggregate Stock Purchase Price in
         effect immediately prior to the exercise of the Conversion Right
         from the aggregate Market Price (as hereinafter defined) for the
         shares of Stock issuable upon exercise of the Warrant immediately
         prior to the exercise of the Conversion Right) by (y) the Market
         Price of one share of Stock immediately prior to the exercise of
         the Conversion Right.  "Market Price" shall mean the Stock Price
         (as defined below) obtained by taking the average over a period of
         thirty consecutive trading days ending on the second trading day
         prior to the date of determination.  As used in this paragraph,
         the term Stock Price shall mean (A) the mean, on each such trading
         day, between the high and low sale price of a share of Stock or if
         no such sale takes place on any such trading day, the mean of the
         closing bid and lowest closing asked prices therefor on any such
         trading day, in each case as officially reported on all national
         securities exchanges on which the Stock is then listed or admitted
         to trading, or (B) if the Stock is not then listed or admitted to
         trading on any national securities exchange, the closing price of
         the Stock on such date, or (C) if no closing price is available on
         any such trading day, the mean between the highest and lowest
         closing bid prices thereof on any such trading date, in the
         over-the-counter market as reported by NASDAQ, (D) if the Stock is
         not then quoted in such system, the mean between the highest and
         lowest bid prices reported by the market makers and dealers for
         the Stock listed as such by the National Quotation Bureau,
         Incorporated or any similar successor organization, or (E) the
         higher of the last bona fide sale made by the Company and the fair
         market value of the Stock as determined by the Board of Directors
         in its good faith judgement.

                   1.3  Exercise of Conversion Right.  The conversion
                        ----------------------------
         rights provided under Section 1.2 hereof may be exercised in whole
         or in part and at any time and from time to time while any
         Warrants remain outstanding.  In order to exercise the conversion
         privilege, the Holder shall surrender to the Company, at its
         offices, this Warrant certificate accompanied by a duly completed
         Notice of Conversion in the form attached hereto as Exhibit A.
         The presentation and surrender shall be deemed a waiver of the
         Holder's obligation to pay all or any portion of the aggregate
         purchase price payable for the shares of Stock issuable upon
         exercise of this Warrant.  This Warrant certificate (or so much
         thereof as shall have been surrendered for conversion) shall be
         deemed to have been converted immediately prior to the close of
         business on the day of surrender of such Warrant certificate for
         conversion in accordance with the foregoing provisions.  As
         promptly as practicable on or after the conversion date, the
         
                                        -2-
<PAGE>
 
         Company shall issue and shall deliver to the Holder (i) a
         certificate or certificates representing the largest number of
         whole shares of Stock to which the Holder shall be entitled as a
         result of the conversion, and (ii) if the Warrant certificate is
         being converted in part only, a new certificate in principal
         amount equal to the unconverted portion of the Warrant
         certificate.  If this Warrant is executed in whole, in lieu of any
         fractional shares of Stock to which the Holder shall be entitled,
         the Company shall pay to the Holder cash in accordance with the
         provisions of Section 12 hereof.

              2.   Shares to Be Fully Paid; Reservation of Shares.  The
                   ----------------------------------------------
         Company covenants and agrees that all shares of Stock which may be
         issued upon the exercise of this Warrant (the "Warrant Shares")
         and all shares of common stock issuable upon conversion of the
         Warrants (the "Conversion Shares") will, upon issuance, be duly
         authorized, validly issued, fully paid and nonassessable and free
         from all preemptive rights of any stockholder and free of all
         taxes, liens and charges with respect to the issue thereof.  The
         Company covenants that it will reserve and keep available a
         sufficient number of shares of its authorized but unissued Stock
         for such exercise and/or conversion, as the case may be.  The
         Company will take all such reasonable action as may be necessary
         to assure that such shares of Stock may be issued as provided
         herein without violation of any applicable law or regulation, or
         of any requirements of any domestic securities exchange or
         automated quotation system upon which the Stock may be listed.

              3.   Adjustment of Stock Purchase Price and Number of Shares.
                   -------------------------------------------------------
         The Stock Purchase Price and, in some cases, the number of shares
         purchasable upon the exercise of this Warrant shall be subject to
         adjustment from time to time upon the occurrence of certain events
         described in this Section 3.

                   3.1  Subdivision or Combination of Stock and Stock
                        ---------------------------------------------
         Dividend.  In case the Company shall at any time subdivide its
         --------
         outstanding shares of Stock into a greater number of shares or
         declare a dividend upon its Stock payable solely in shares of
         Stock, the Stock Purchase Price in effect immediately prior to
         such subdivision or declaration shall be proportionately reduced,
         and the number of shares issuable upon exercise of the Warrant
         shall be proportionately increased.  Conversely, in case the
         outstanding shares of Stock of the Company shall be combined into
         a smaller number of shares, the Stock Purchase Price in effect
         immediately prior to such combination shall be proportionately
         increased, and the number of shares issuable upon exercise of the
         Warrant shall be proportionately reduced.

                   3.2  Intentionally Omitted.
                        ---------------------

                   3.3  Notice of Adjustment.  Promptly after adjustment of
                        --------------------
         the Stock Purchase Price or any increase or decrease in the number
         of shares purchasable upon the exercise of this Warrant, the
         Company shall give written notice thereof, by first class mail,
         postage prepaid, addressed to the registered holder of this
         Warrant at the address of such holder as shown on the books of the
         Company.  The notice shall be signed by the Company's chief
         financial officer and shall state the effective date of the
         adjustment and the Stock Purchase Price resulting from such
         adjustment and the increase or decrease, if any, in the number of
         shares purchasable at such price upon the exercise of this
         Warrant, setting forth in reasonable detail the method of
         calculation and the facts upon which such calculation is based.

         its Stock payable in stock (other than a dividend payable solely
         in shares of Stock) or make any special dividend or other
         distribution to the holders of its Stock;

                        (c)  there shall be any consolidation or merger of
         the Company with another corporation, or a sale of all or
         substantially all of the Company's assets to another corporation;
         or

                        (d)  there shall be a voluntary or involuntary
         dissolution, liquidation or winding-up of the Company;

         then, in any one or more of said cases, the Company shall give, by
         certified or registered mail, postage prepaid, addressed to the
         registered holder of this Warrant at the address of such holder as
         shown on the books of the Company, (i) at least 30 days' prior
         written notice of the date on which the books of the Company shall
         close or a record shall be taken for such dividend, distribution
         or subscription rights or for determining rights to vote in
         respect of any such dissolution, liquidation or winding-up;
         (ii) at least 10 days' prior written notice of the date on which
         the books of the Company shall close or a record shall be taken

         and (iii) in the case of any such reorganization,
         reclassification, consolidation; merger, sale, dissolution,
         liquidation or winding-up, at least 30 days' written notice of the
         date when the same shall take place.  Any notice given in
         accordance with clause (i) above shall also specify, in the case
         of any such dividend, distribution or option rights, the date on
         which the holders of Stock shall be entitled thereto.  Any notice
         given in accordance with clause (iii) above shall also specify the
         date on which the holders of Stock shall be entitled to exchange
         their Stock for securities or other property deliverable upon such
         reorganization, reclassification, consolidation, merger, sale,
         dissolution, liquidation or winding-up, as the case may be.  If
         the Holder of the Warrant does not exercise this Warrant prior to
         the occurrence of an event described above, except as provided in
         Sections 3.1 and 3.5, the Holder shall not be entitled to receive
         the benefits accruing to existing holders of the Stock in such
         event.

                   3.5  Changes in Stock.  In case at any time following
                        ----------------
         the date hereof, the Company shall be a party to any transaction
         (including, without limitation, a merger, consolidation, sale of
         all or substantially all of the Company's assets or
         recapitalization of the Stock) in which the previously outstanding
         Stock shall be changed into or exchanged for different securities
         of the Company or common stock or other securities of another
         corporation or interests in a noncorporate entity or other
         property (including cash) or any combination of any of the
         foregoing (each such transaction being herein called the
         "Transaction" and the date of consummation of the Transaction
         being herein called the "Consummation Date"), then, as a condition
         of the consummation of the Transaction, lawful and adequate
         provisions shall be made so that each Holder, upon the exercise
         hereof at any time on or after the Consummation Date, shall be
         entitled to receive; and this Warrant shall thereafter represent
         the right to receive, in lieu of the Stock issuable upon such
         exercise prior to the Consummation Date, the highest amount of
         securities or other property to which such Holder would actually

                                        -4-
<PAGE>
 
         have been entitled as a stockholder upon the consummation of the
         Transaction if such Holder had exercised such Warrant immediately
         prior thereto.  The provisions of this Section 3.5 shall similarly
         apply to successive Transactions.

              4.   Issue Tax.  The issuance of certificates for shares of
                   ---------
         Stock upon the exercise of the Warrant shall be made without
         charge to the holder of the Warrant for any issue tax in respect
         thereof; provided, however, that the Company shall not be required
         to pay any tax which may be payable in respect of any transfer
         involved in the issuance and delivery of any certificate in a name
         other than that of the then holder of the Warrant being exercised.

              5.   No Voting or Dividend Rights; Limitation of Liability.
                   -----------------------------------------------------
         Nothing contained in this Warrant shall be construed as conferring
         upon the holder hereof the right to vote or to consent or to
         receive notice as a stockholder in respect of meetings of
         stockholders for the election of directors of the Company or any
         other matters or any rights whatsoever as a stockholder of the
         Company.  Except for the adjustment to the Stock Purchase Price
         pursuant to Section 3.1 in the event of a dividend on the Stock
         payable in shares of Stock, no dividends or interest shall be
         payable or accrued in respect of this Warrant or the interest
         represented hereby or the shares purchasable hereunder until, and
         only to the extent that, this Warrant shall have been exercised.
         No provisions hereof, in the absence of affirmative action by the
         holder to purchase shares of Stock, and no mere enumeration herein
         of the rights or privileges of the holder hereof, shall give rise
         to any liability of such holder for the Stock Purchase Price or as
         a stockholder of the Company whether such liability is asserted by
         the Company or by its creditors.

              6.   Restrictions on Transferability of Securities:

         therefrom under said Act.

                   6.2  Restrictive Legend.  Each certificate representing
                        ------------------

         Securities upon any stock split, stock dividend, recapitalization,
         merger, consolidation or similar event, shall be stamped or
         otherwise imprinted with a legend substantially in the following
         form (in addition to any legend required under applicable state
         securities laws):

                   THE SECURITIES REPRESENTED HEREBY HAVE NOT
                   BEEN REGISTERED UNDER THE SECURITIES ACT OF
                   1933, AS AMENDED ("ACT"), OR ANY STATE

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

                        7.2.1  Request and Filing.  If the Company shall
                               ------------------
         receive a written request from KBL Healthcare, Inc., as the holder
         of Registrable Securities or on behalf of other holders of
         Registrable Securities, to register all or part of the Registrable
         Securities, the Company shall, as promptly as practicable, prepare
         and file with the Commission a Registration Statement sufficient
         to permit the public offering and sale of such Registrable
         Securities and will use its best efforts through its officers,
         directors, auditors and counsel to cause such Registration
         Statement to become effective as promptly as practicable and to
        
                                        -6-
<PAGE>
 
         maintain the effectiveness thereof for at least nine months;
         provided, however, that the Company shall not be obligated to file
         --------  -------
         such a Registration Statement covering the Registrable Securities
         until twelve months following the completion of its initial public
         offering and, provided, further, that the Company shall only be
                       --------  -------
         obligated to file three Registration Statements for which all
         expenses incurred in connection with such Registration (other than
         the fees and disbursements of counsel for holders of Registrable
         Securities and underwriting discounts, if any, payable in respect
         of the Registrable Securities sold by such holders) shall be borne
         by the Company.  In addition to the foregoing, at such time as it
         becomes eligible to do so the Company shall file a Registration
         Statement covering all of the Registrable Securities eligible to
         be registered on such Form on Form S-3, and shall use its best
         efforts to cause such Registration Statement to become effective
         as promptly as practicable and to maintain the effectiveness
         thereof until the Restriction Termination Date.  Notwithstanding
         the foregoing, the Company shall have no obligation to comply with
         the foregoing provisions of this Section 7.2 if, in the opinion of
         counsel to the Company reasonably acceptable to the person or
         persons from whom, or on whose behalf, such written request has
         been received, registration under the Securities Act is not
         required for the transfer of the Registrable Securities in the
         amount and manner proposed by such person or persons.  The rights
         of KBL Healthcare, Inc. to request the registration of the
         Registrable Securities pursuant to this Section 7.2 shall inure to
         the benefit of KBL Healthcare, Inc., its successors and assigns;
         provided, however, that such rights shall not be deemed to have
         been assigned by virtue of any assignment of this Warrant, in
         whole or in part, unless such assignment specifically provides for
         an assignment of the rights of KBL Healthcare, Inc. under this
         Section 7.2.

                        7.2.2  Underwritten Offering.  KBL Healthcare,
                               ---------------------
         Inc., as the holder of Registrable Securities or on behalf of
         other holders of Registrable Securities, on three occasions may
         request that its Registrable Securities be sold by means of an
         underwritten public offering.  KBL Healthcare, Inc., as the holder
         of Registrable Securities or on behalf of other holders of
         Registrable Securities, shall enter into an underwriting agreement
         in customary form with the managing underwriter or underwriters
         selected for such underwriting, which underwriter must also be
         reasonably acceptable to the Company.

                   7.3  Company Registration.  If (but without any
                        --------------------
         obligation to do so) the Company proposes to Register at any time
         prior to the Restriction Termination Date (including for this
         purpose a Registration effected by the Company for stockholders
         other than the Holder) any of its stock or other securities under
         the Act in connection with the underwritten public offering of
         such securities solely for cash (other than a Registration of
         securities in connection with mergers, acquisitions, exchange
         offers, distributions to the Company's stockholders, or stock
         option or other employee benefit plans or a Registration in any
         form which does not include substantially the same information as
         would be required to be included in a registration statement
         covering the sale of the Registrable Securities), the Company
         shall, at each such time, promptly give Holder written notice of
         such Registration.  Upon the written request of Holder given
         within 15 days after mailing of such notice by the Company, the
         Company shall, subject to the following provisions, use all
         reasonable efforts to cause to be included in such Registration
         all of the Registrable Securities that Holder has requested to be
         included.


                                        -7-
<PAGE>
 
              The Company shall not be required under this Section 7.3 to
         include any of the Holder's securities in an underwritten offering
         of the Company's securities unless such Holder accepts the terms
         of the underwriting as agreed upon between the Company and the
         underwriters selected by it, and then only in such quantity as
         will not, in the opinion of the managing underwriters, interfere
         with the successful marketing of the offering by the Company.

                   7.4  Blue Sky.  In the event of any Registration
                        -------- 
         pursuant to this Section 7, the Company will exercise its best
         efforts to Register and qualify the Registrable Securities covered
         by the Registration Statement under such other securities or Blue
         Sky laws of such jurisdictions as shall be reasonably requested by
         the Holders for the distribution of such securities; provided,
         however, that the Company shall not be required to qualify to do
         business, to file a general consent to service of process or to
         subject itself to taxation in any state or jurisdiction in which
         it is not now qualified.  The Company will furnish to the Holder
         written advice of its counsel with respect to registration or
         exemption of such Registrable Securities in such jurisdictions.

                   7.5  Expenses of Registration.  All Registration
                        ------------------------     
         Expenses incurred in connection with a Registration pursuant to
         Section 7.2 shall be borne by the Company.  All Selling Expenses
         shall be borne by the Holder.

                   7.6  Registration Procedures.
                        -----------------------

                        7.6.1  Advice by Company.  The Company will keep
                               -----------------
         the Holder advised as to the initiation and completion of such
         Registration.  At its expense the Company will (i) use its best
         efforts to keep such Registration effective until the earlier of
         the date on which the Holder has completed the distribution
         described in the Registration Statement or the Restriction
         Termination Date with respect to such Securities; and (ii) furnish
         such number of prospectuses (including preliminary prospectuses)
         and other documents as the Holder from time to time may reasonably
         request.

                        7.6.2  Amendments.  The Company will promptly
                               ---------- 
         prepare and file with the Commission such amendments and
         prospectus supplements, including post-effective amendments, to
         the Registration Statement as the Company determines may be
         necessary or appropriate, and use its best efforts to have such
         post-effective amendments declared effective as promptly as
         practicable; cause the related prospectus to be supplemented by
         any prospectus supplement, and as so supplemented, to be filed
         with the Commission; and notify the Holder of any securities
         included in such Registration Statement and the underwriter
         thereof, if any, promptly when a prospectus, any prospectus
         supplement or post-effective amendment must be filed or has been
         filed and, with respect to any post-effective amendment, when the
         same has become effective.

                        7.6.3  Underwritten Offerings.  At the request of
                               ----------------------
         the Holder requesting Registration of Registrable Securities
         pursuant to this Section 7, on the date that such Registrable
         Securities are delivered to the underwriters for sale pursuant to
         such Registration in an underwritten offering pursuant to
         Section 7.2, the Company will (a) furnish (i) an opinion, dated as
         of such date, of the independent counsel representing the Company
         for the purposes of such Registration, addressed to the
         underwriter, in a customary form and covering matters of the type
         customarily covered in such legal opinions; and (ii) a comfort
         letter dated as of such date, from the independent certified public 
         accountants of the Company addressed to the underwriter in
         
                                      -8-
<PAGE>
 
         a customary form and covering matters of the type customarily
         covered by such comfort letters; such opinion of counsel shall
         additionally cover such other legal matters with respect to the
         Registration in respect of which such opinion is being given as
         such underwriter may reasonably request and such letter from the
         independent certified public accountants shall additionally cover
         such other financial matters (including information as to the
         period ending not more than five business days prior to the date
         of such letter) with respect to the Registration in respect of
         which such letter is being given as such underwriter may
         reasonably request; and (b) with such Holder, enter into customary
         agreements (including an underwriting agreement in customary form)
         and take such other actions as are reasonably required in order to
         expedite or facilitate the disposition of such Registrable
         Securities.

                   7.7  Information Furnished by Holder.  It shall be a
                        -------------------------------
         condition precedent to the Company's obligations under this
         Agreement that the Holder furnish to the Company in writing such
         information regarding such Holder and the distribution proposed by
         such Holder as the Company may reasonably request.

         Company will indemnify Holder, each of its officers, directors and
         partners, and each person controlling such Holder, with respect to
         which Registration, qualification or compliance of Registrable
         Securities has been effected pursuant to this Agreement, and each
         underwriter, if any, and each of its officers, directors,
         constituent partners, and each person who controls any underwriter
         against all claims, losses, damages or liabilities (or actions in
         respect thereof) to the extent such claims, losses, damages or
         liabilities arise out of or are based upon any untrue statement
         (or alleged untrue statement) of a material fact contained in any
         prospectus or any related Registration Statement incident to any
         such Registration, qualification or compliance, 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, or any violation by the Company of any rule or
         regulation promulgated under the Securities Act applicable to the
         Company and relating to action or inaction required of the Company
         in connection with any such Registration; and the Company will
         reimburse Holder, each such underwriter and each person who
         controls such Holder or underwriter, for any legal and any other
         expenses reasonably incurred in connection with investigating or
         defending any such claim, loss, damage, liability or action;
         provided, however, that the indemnity contained in this
         Section 7.8.1 shall not apply to amounts paid in settlement of any
         such claim, loss, damage, liability or action if settlement is
         effected without the consent of the Company (which consent shall
         not unreasonably be withheld or delayed); and provided, further,
         that the Company will not be liable in any such case to the extent
         that any such claim, loss, damage, liability or expense arises out
         of or is based upon any untrue statement or omission based upon
         written information furnished to the Company by Holder,
         underwriter or controlling person for use in connection with the
         offering of securities of the Company.  Notwithstanding the above,
         the foregoing indemnity agreement is subject to the condition
         that, insofar as it relates to any such untrue statement; alleged
         untrue statement, omission or alleged omission made in a
         preliminary prospectus, such indemnity agreement shall not inure
         to the benefit of any underwriter or Holder, if there is no
         underwriter, if a copy of the final prospectus was not furnished
         to the person asserting the loss, liability, claim or damage at or
         prior to the time such action is required by the Securities Act if

                                       -9-

         the final prospectus corrected the untrue statement or omission or
         alleged untrue statement or omission.

                        7.8.2  Holders' Indemnification of Company.  Holder
                               -----------------------------------
         will, if Registrable Securities held by Holder are included in the
         Securities as to which a Registration is being effected pursuant
         to this Agreement, indemnify the Company, each of its directors
         and officers, each underwriter, if any, of the Company's
         securities covered by such a Registration Statement, each person
         who controls the Company or such underwriter within the meaning of
         the Securities Act, against all claims, losses, damages and
         liabilities (or actions in respect thereof) arising out of or
         based upon any untrue statement (or alleged untrue statement) of a
         material fact contained in any such Registration Statement or
         related prospectus, 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; and will reimburse
         the Company, such directors, officers, partners, persons,
         underwriters or control persons for any legal and any other
         expenses reasonably incurred in connection with investigating or
         defending any such claim, loss, damage, liability or action, in
         each case to the extent, but only to the extent, that such untrue
         statement (or alleged untrue statement) or omission (or alleged
         omission) is made in such Registration Statement or prospectus in
         reliance upon and in conformity with written information furnished
         to the Company by Holder and stated to be specifically for use in
         connection with the offering of Securities of the Company.

                        7.8.3  Indemnification Procedure.  Promptly after
                               -------------------------
         receipt by an indemnified party under this Section 7.8 of notice
         of the commencement of any action, such indemnified party will, if
         a claim in respect thereof is to be made against an indemnifying
         party under this Section 7.8, notify the indemnifying party in
         writing of the commencement thereof and generally summarize such
         action.  The indemnifying party shall have the right to
         participate in and to assume the defense of such claim, and shall
         be entitled to select counsel for the defense of such claim with
         the approval of any parties entitled to indemnification, which
         approval shall not be unreasonably withheld.  Notwithstanding the
         foregoing, the parties entitled to indemnification shall have the
         right to employ separate counsel (reasonably satisfactory to the
         indemnifying party) to participate in the defense thereof, but the
         fees and expenses of such counsel shall be the expense of such
         indemnified parties unless the named parties to such action or
         proceedings include both the indemnifying party and the
         indemnified parties and the indemnifying party or such indemnified
         parties shall have been advised by counsel that there are one or
         more legal defenses available to it which are different from or
         additional to those available to the indemnifying party (in which
         case, if the indemnified party notifies the indemnifying party in
         writing that it elects to employ separate counsel at the
         reasonable expense of the indemnifying party, the indemnifying
         party shall not have the right to assume the defense of such
         action or proceeding on behalf of the indemnified party, as the
         case may be, it being understood, however, that the indemnifying
         party shall not, in connection with any such action or proceeding
         or separate or substantially similar or related action or
         proceeding in the same jurisdiction arising out of the same
         general allegations or circumstances, be liable for the reasonable
         fees and expenses of more than one separate counsel at any time
         for the indemnifying party and all indemnified parties, which
         counsel shall be designated in writing by the Holders of a
         majority of the Registrable Securities).  If the indemnifying
         party withholds consent to a settlement or proposed settlement by
        
                                       -10-
<PAGE>
 
         the indemnified party, it shall acknowledge to the indemnified
         party its indemnification obligations hereunder.

                        7.8.4  Contribution.  If the indemnification
                               ------------  
         provided for in this Section 7.8 from an indemnifying party is
         unavailable to an indemnified party hereunder in respect to any
         losses, claims, damages, liabilities or expenses referred to
         herein, then the indemnifying party, in lieu of indemnifying such
         indemnified party, shall contribute to the amount paid or payable
         by such indemnified party as a result of such losses, claims,
         damages, liabilities or expenses in such proportion as is
         appropriate to reflect the relative fault of the indemnifying
         party and indemnified party in connection with the statements or
         omissions which result in such losses, claims, damages,
         liabilities or expenses, as well as any other relevant equitable
         considerations.  The relative fault of such indemnifying party and
         indemnified party shall be determined by reference to, among other
         things, whether the untrue or alleged untrue statement of a
         material fact or the omission or alleged omission to state a
         material fact relates to information supplied by such indemnifying
         party or indemnified party and the parties' relative intent,
         knowledge, access to information supplied by such indemnifying
         party or indemnified party and opportunity to correct or prevent
         such statement or omission.  The amount paid or payable by a party
         as a result of the losses, claims, damages, liabilities and
         expenses referred to above shall deemed to include any legal or
         other fees or expenses reasonably incurred by such party in
         connection with investigating or defending any action, suit,
         proceeding or claim.

                   7.9  Transfer of Rights.  As defined herein, the term
                        ------------------  
         Transfer shall mean any sale, hypothecation, transfer or other
         disposition of Registrable Securities or any interest therein
         other than a sale registered under a Registration Statement.  The
         right to cause the Company to Register Registrable Securities
         granted by the Company to Holder under this Section 7 may be
         assigned by Holder.

                   7.10  No-Action Letter or Opinion of Counsel in Lieu of
                         -------------------------------------------------
         Registration.  Notwithstanding anything else in this Agreement, if
         ------------
         the Company shall have obtained from the Commission a "no-action"
         letter in which the Commission has indicated that it will take no
         action if, without Registration under the Securities Act, the
         Holder disposes of Registrable Securities covered by any request
         for Registration made under this Section in the specific manner in
         which the Holder proposes to dispose of the Registrable Securities
         included in such request (including, without limitation, inclusion
         of such Registrable Securities in an underwriting initiated by
         either the Company or the Holder), or if in the opinion of counsel
         for the Company concurred in by counsel for the Holder, which
         concurrence shall not be unreasonably withheld, no Registration
         under the Securities Act is required in connection with such
         disposition, the Registrable Securities included in such request
         shall not be eligible for Registration under this Agreement;
         provided, however, that any Registrable Securities not so disposed
         of shall be eligible for Registration in accordance with the terms
         of this Agreement with respect to other proposed dispositions to
         which this Section 7.10 does not apply.  In addition, the
         obligation of the Company to file or maintain the effectiveness of
         any Registration Statement under this Section 7 shall be suspended
         with respect to any Securities held by the Holder at any time
         following the Restriction Termination Date with respect to such
         Securities.

         Company shall be delivered or shall be sent by certified or
         registered mail, postage prepaid, to each such holder at its
         address as shown on the books of the Company or to the Company at

         are inserted for convenience only and do not constitute a part of

              11.  Lost Warrants or Stock Certificates.  The Company
                   -----------------------------------  
         represents and warrants to Holder that upon receipt of evidence
         reasonably satisfactory to the Company of the loss, theft,
         destruction or mutilation of any Warrant or stock certificate and,
         in the case of any such loss, theft or destruction, upon receipt
         of an indemnity and, if requested, bond reasonably satisfactory to
         the Company, or in the case of any such mutilation, upon surrender
         and cancellation of such Warrant or stock certificate, the Company
         at its expense will make and deliver a new Warrant or stock
         certificate, of like tenor, in lieu of the lost, stolen, destroyed
         or mutilated Warrant or stock certificate.

         issuing any fractional share pay the holder entitled to such
         fraction a sum in cash equal to the fair market value of any such
         fractional interest as it shall appear on the public market, or if
         there is no public market for such shares, then as shall be
         reasonably determined by the Company.

              IN WITNESS WHEREOF, the Company has caused this Warrant to be
         executed by its officer, thereunto duly authorized as of this
         29th day of September, 1993.

         each case to the extent, but only to the extent, that such untrue

         reliance upon and in conformity with written information furnished
         to the Company by Holder and stated to be specifically for use in
         connection with the offering of Securities of the Company.

                        1.7.3  Indemnification Procedure.  Promptly after
                               -------------------------
         receipt by an indemnified party under this Section 1.7 of notice
         of the commencement of any action, such indemnified party will, if
         a claim in respect thereof is to be made against an indemnifying
         party under this Section 1.7, notify the indemnifying party in
         writing of the commencement thereof and generally summarize such
         action.  The indemnifying party shall have the right to
         participate in and to assume the defense of such claim, and shall
         be entitled to select counsel for the defense of such claim with
         the approval of any parties entitled to indemnification, which
         approval shall not be unreasonably withheld.  Notwithstanding the
         foregoing, the parties entitled to indemnification shall have the
         right to employ separate counsel (reasonably satisfactory to the
         indemnifying party) to participate in the defense thereof, but the
         fees and expenses of such counsel shall be the expense of such
         indemnified parties unless the named parties to such action or

                                      -4-
<PAGE>
 
         proceedings include both the indemnifying party and the
         indemnified parties and the indemnifying party or such indemnified
         parties shall have been advised by counsel that there are one or
         more legal defenses available to it which are different from or
         additional to those available to the indemnifying party (in which
         case, if the indemnified party notifies the indemnifying party in
         writing that it elects to employ separate counsel at the
         reasonable expense of the indemnifying party, the indemnifying
         party shall not have the right to assume the defense of such
         action or proceeding on behalf of the indemnified party, as the
         case may be, it being understood, however, that the indemnifying
         party shall not, in connection with any such action or proceeding
         or separate or substantially similar or related action or
         proceeding in the same jurisdiction arising out of the same
         general allegations or circumstances, be liable for the reasonable
         fees and expenses of more than one separate counsel at anytime for
         the indemnifying party and all indemnified parties, which counsel
         shall be designated in writing by the Holders of a majority of the
         Registrable Securities).  If the indemnifying party withholds
         consent to a settlement or proposed settlement by the indemnified
         party, it shall acknowledge to the indemnified party its
         indemnification obligations hereunder.

                        1.7.4  Contribution.  If the indemnification
                               ------------ 
         provided for in this Section 1.7 from an indemnifying party is
         unavailable to an indemnified party hereunder in respect to any
         losses, claims, damages, liabilities or expenses referred to
         herein, then the indemnifying party, in lieu of indemnifying such
         indemnified party, shall contribute to the amount paid or payable
         by such indemnified party as a result of such losses, claims,
         damages, liabilities or expenses in such proportion as is
         appropriate to reflect the relative fault of the indemnifying
         party and indemnified party in connection with the statements or
         omissions which result in such losses, claims, damages,
         liabilities or expenses, as well as any other relevant equitable
         considerations.  The relative fault of such indemnifying party and
         indemnified party shall be determine by reference to, among other
         things, whether the untrue or alleged untrue statement of a
         material fact or the omission or the alleged omission to state a
         material fact relates to information supplied by such indemnifying
         party or indemnified party and the parties' relative intent,
         knowledge, access to information supplied by such indemnifying
         party or indemnified party and opportunity to correct or prevent
         such statement or omission.  The amount paid or payable by a party
         as a result of the losses, claims, damages, liabilities and
         expenses referred to above shall deemed to include any legal or
         other fees or expenses reasonably incurred by such party in
         connection with investigation or defending any action, suit,
         proceeding or claim.

                   1.8  Transfer of Rights.  As defined herein, the term
                        ------------------    
         Transfer shall mean any sale, hypothecation, transfer or other
         disposition of Registrable Securities or any interest therein
         other than a sale registered under a Registration Statement.  The
         right to cause the Company to Register Registrable Securities
         granted by the Company to Holder under this Section 1 may be
         assigned by Holder in connection with any sale or transfer of such
         Registrable Securities.

              2.   This Agreement may only be amended with the written
         consent of holders of 51% of the Registrable Securities then
         outstanding.  Any amendment effected in accordance with this
         Section 2 shall be binding upon each holder of any Registrable
