                               WARRANT AGREEMENT

          THIS WARRANT AGREEMENT (this "Agreement") is made and entered into as
of _______________, 1999, between SUNSTAR HEALTHCARE, INC., a Delaware
corporation (the "Company") and [INVESTOR] ("Holder").

                                R E C I T A L S
                                - - - - - - - -

          WHEREAS, the Company proposes to issue to Holder [ ] warrants (the
"Warrants"), each such Warrant entitling the holder thereof to purchase one
share of Common Stock, $.001 par value, of the Company (the "Exercise Shares,"
"Shares," or the "Common Stock"); and

          WHEREAS, the Warrants which are the subject of this Agreement will be
issued by the Company to Holder as part of consideration payable to Holder in
connection with an investment by the Holder pursuant to the concurrent private
offering of the Company (the "Offering").

          NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereto agree as follows:

                               A G R E E M E N T
                               - - - - - - - - -

     1.   Warrant Certificates. The warrant certificates to be delivered
          --------------------
pursuant to this Agreement (the "Warrant Certificates") shall be in the form set
forth in Annex A, attached hereto and made a part hereof, with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Warrant Agreement.

     2.   Right to Exercise Warrants. Each Warrant may be exercised from the
          --------------------------
date of this Agreement until 11:59 P.M. (Eastern time) on the date that is five
years after the date of this Agreement (the "Expiration Date"). Each Warrant not
exercised on or before the Expiration Date shall expire.

          Each Warrant shall entitle its holder to purchase from the Company one
share of Common Stock at an exercise price of $5.00 per share, subject to
adjustment as set forth below ("Exercise Price").

          The Company shall not be required to issue fractional shares of
capital stock upon the exercise of this Warrant or to deliver Warrant
Certificates which evidence fractional shares of capital stock. In the event
that a fraction of an Exercise Share would, except for the provisions of this
paragraph 2, be issuable upon the exercise of this Warrant, the Company shall
pay to the Holder exercising the Warrant an amount in cash equal to such
fraction multiplied by the current market value of the Exercise Share. For
purposes of this Agreement, the current market value shall be determined as
follows:

          (a) if the Exercise Shares are traded in the over-the-counter market
and not on any national securities exchange and not in the NASDAQ Reporting
System, the average of the mean between the last bid and asked prices per share,
as reported by the National Quotation Bureau, Inc., or an equivalent generally
accepted reporting service, for the last business day prior to the date on which
this Warrant is exercised, or, if not so reported, the average of the closing
bid and asked prices for an Exercise Share as furnished to the Company by any
member of the National Association of Securities Dealers, Inc., selected by the
Company for that purpose.

          (b) if the Exercise Shares are listed or traded on a national
securities exchange or in the NASDAQ Reporting System, the closing price on the
principal national securities exchange on which they are so listed or traded or
in the NASDAQ Reporting System, as the case may be, on the last business day
prior to the date

                                       1
<PAGE>
 
of the exercise of this Warrant. The closing price referred to in this Clause
(b) shall be the last reported sales price or, in case no such reported sale
takes place on such day, the average of the reported closing bid and asked
prices, in either case on the national securities exchange on which the Exercise
Shares are then listed or in the NASDAQ Reporting System; or

          (c) if no such closing price or closing bid and asked prices are
available, as determined in any reasonable manner as may be prescribed by the
Board of Directors of the Company.

     3.   Mutilated or Missing Warrant Certificates. In case any of the Warrant
          -----------------------------------------
Certificates shall be mutilated, lost, stolen or destroyed prior to its
expiration date, the Company shall issue and deliver, in exchange and
substitution for and upon cancellation of the mutilated Warrant Certificate, or
in lieu of and in substitution for the Warrant Certificate lost, stolen or
destroyed, a new Warrant Certificate of like tenor and representing an
equivalent right or interest.

     4.   Reservation of Shares. The Company will at all times reserve and keep
          ---------------------
available, free from preemptive rights, out of the aggregate of its authorized
but unissued Shares or its authorized and issued Shares held in its treasury for
the purpose of enabling it to satisfy its obligation to issue Shares upon
exercise of Warrants, the full number of Shares deliverable upon the exercise of
all outstanding Warrants.

          The Company covenants that all Shares which may be issued upon
exercise of Warrants will be validly issued, fully paid and nonassessable
outstanding Shares of the Company.

     5.   Rights of Holder. The Holder shall not, by virtue of anything
          ----------------
contained in this Warrant Agreement or otherwise, prior to exercise of this
Warrant, be entitled to any right whatsoever, either in law or equity, of a
stockholder of the Company, including without limitation, the right to receive
dividends or to vote or to consent or to receive notice as a shareholder in
respect of the meetings of shareholders or the election of directors of the
Company of any other matter.

     6.   Investment Intent. Holder represents and warrants to the Company that
          -----------------
Holder is acquiring the Warrants for investment and with no present intention of
distributing or reselling any of the Warrants.

     7.   Certificates to Bear Language. The Warrants and the certificate or
          -----------------------------
certificates therefor shall bear the following legend by which each holder shall
be bound:

          "THE WARRANTS REPRESENTED BY THIS CERTIFICATE AND THE SHARES
          OF COMMON STOCK (OR OTHER SECURITIES) ISSUABLE UPON EXERCISE
          THEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933. THE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE
          ABSENCE OF SUCH REGISTRATION OR TRANSFERRED IN THE ABSENCE
          OF SUCH REGISTRATION OR AN OPINION OF COUNSEL THAT AN
          EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE."

          The Shares and the certificate or certificates evidencing any
such Shares shall bear the following legend:

          "THE SHARES (OR OTHER SECURITIES) REPRESENTED BY THIS
          CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
          ACT OF 1933. THE SHARES MAY NOT BE SOLD OR TRANSFERRED IN
          THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF COUNSEL
          THAT AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS
          AVAILABLE."

                                       2
<PAGE>
 
          Certificates for Warrants without such legend shall be issued if such
warrants or shares are sold pursuant to an effective registration statement
under the Securities Act of 1933 (the "Act") or if the Company has received an
opinion from counsel reasonably satisfactory to counsel for the Company, that
such legend is no longer required under the Act.

     8.   Registration Rights. The Company is obligated to register all of the
          -------------------
Exercise Shares underlying the Warrants in a registration statement on the
appropriate form with the Securities and Exchange Commission (the "Commission")
not later than 90 days following the closing of the Offering, so that all
Warrantholders shall be entitled to sell the Exercise Shares in the public
market immediately upon the expiration of the one-year holding period from date
of initial sale of any such Warrants (the "Mandatory Registration Right").

     9.   Adjustment of Number of Shares and Class of Capital Stock Purchasable.
          ---------------------------------------------------------------------
The Number of Shares and Class of Capital Stock purchasable under this Warrant
Agreement are subject to adjustment from time to time as set forth in this
Section 9.

          (a)   Adjustment for Change in Capital Stock.  If the Company:
                --------------------------------------
               
                (i)   pays a dividend or makes a distribution on its Common
Stock, in each case, in shares of its Common Stock;

                (ii)  subdivides its outstanding shares of Common Stock into a
greater number of shares;

                (iii) combines its outstanding shares of Common Stock into a
smaller number of shares;

                (iv)  makes a distribution on its Common Stock in shares of its
capital stock other than Common Stock; or

                (v)   issues by reclassification of its shares of Common Stock
any shares of its capital stock;

then the number and classes of shares purchasable upon exercise of each Warrant
in effect immediately prior to such action shall be adjusted so that the holder
of any Warrant thereafter exercised may receive the number and classes of shares
of capital stock of the Company which such holder would have owned immediately
following such action if such holder had exercised the Warrant immediately prior
to such action.

          For a dividend or distribution the adjustment shall become effective
immediately after the record date for the dividend or distribution. For a
subdivision, combination or reclassification, the adjustment shall become
effective immediately after the effective date of the subdivision, combination
or reclassification.

          If after an adjustment the holder of a Warrant upon exercise of it may
receive shares of two or more classes of capital stock of the Company, the Board
of Directors of the Company shall in good faith determine the allocation of the
adjusted Exercise Price between or among the classes of capital stock. After
such allocation, that portion of the Exercise Price applicable to each share of
each such class of capital stock shall thereafter be subject to adjustment on
terms comparable to those applicable to Common Stock in this Agreement.
Notwithstanding the allocation of the Exercise Price between or among shares of
capital stock as provided by this Section 9(a), a Warrant may only be exercised
in full by payment of the entire Exercise Price currently in effect.

          (b)   Consolidation, Merger or Sale of the Company. If the Company is
                --------------------------------------------
a party to a consolidation, merger or transfer of assets which reclassifies or
changes its outstanding Common Stock, the successor corporation (or corporation
controlling the successor corporation or the Company, as the case may be) shall
by operation of law assume the Company's obligations under this Warrant
Agreement. Upon consummation of such transaction the Warrants shall
automatically become exercisable for the kind and amount of securities, cash or

                                       3
<PAGE>
 
other assets which the holder of a Warrant would have owned immediately after
the consolidation, merger or transfer if the holder had exercised the Warrant
immediately before the effective date of such transaction. As a condition to the
consummation of such transaction, the Company shall arrange for the person or
entity obligated to issue securities or deliver cash or other assets upon
exercise of the Warrant to, concurrently with the consummation of such
transaction, assume the Company's obligations hereunder by executing an
instrument so providing and further providing for adjustments which shall be as
nearly equivalent as may be practical to the adjustments provided for in this
Section 9.

         10. Successors. All the covenants and provisions of this Agreement by
             ----------  
or for the benefit of the Company or Holder shall bind and inure to the benefit
of their respective successor and assigns hereunder.

         11. Counterparts. This Agreement may be executed in any number of
             ------------  
counterparts and each of such counterparts shall for all proposes be deemed to
be an original, and such counterparts shall together constitute by one and the
same instrument.

         12. Notices. All notices or other communications under this Warrant
             -------
shall be in writing and shall be deemed to have been given if delivered by hand
or mailed by certified mail, postage prepaid, return receipt requested,
addressed as follows: if to the Company: SunStar Healthcare, Inc., 300
International Parkway, Suite 230, Heathrow, Florida, 32746, Attention:
President, and to the Holder: at the address of the Holder appearing on the
books of the Company or the Company's transfer agent, if any.

             Either the Company or the Holder may from time to time change
the address to which notices to it are to be mailed hereunder by notice in
accordance with the provisions of this Section 12.

         13. Supplements and Amendments. The Company may from time to time
             --------------------------  
supplement or amend this Warrant Agreement without the approval of any Holders
of Warrants in order to cure any ambiguity or to be correct or supplement any
provision contained herein which may be defective or inconsistent with any other
provision, or to make any other provisions in regard to matters or questions
herein arising hereunder which the Company may deem necessary or desirable and
which shall not materially adversely affect the interest of the Holder.

         14. Severability. If for any reason any provision, paragraph or term of
             ------------  
this Warrant Agreement is held to be invalid or unenforceable, all other valid
provisions herein shall remain in full force and effect and all terms,
provisions and paragraphs of this Warrant shall be deemed to be severable.

         15. Governing Law and Venue. This Warrant shall be deemed to be a
             -----------------------  
contract made under the laws of the State of California and for all purposes
shall be governed and construed in accordance with the laws of said State. Any
proceeding arising under this Warrant Agreement shall be instituted in the State
of California.

         16. Headings. Paragraphs and subparagraph headings, used herein are
             --------  
included herein for convenience of reference only and shall not affect the
construction of this Warrant Agreement nor constitute a part of this Warrant
Agreement for any other purpose.

             IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed, as of the date and year first above written.

                         REGISTRATION RIGHTS AGREEMENT

                                    , 1999
                                ----------

               The parties to this agreement are SunStar Healthcare, Inc. a
Delaware corporation (the "Company"), and each of the other individuals or
entities that has executed a signature page to this agreement (collectively, the
"Stockholders").

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

               Simultaneously with the execution and delivery of this agreement,
the Stockholders are acquiring shares of Series A Preferred Stock, par value
$.001 per share (the "Series A Preferred Stock"), which is convertible into
shares of the Company's Common Stock, par value $.001 per share (the "Common
Stock"), and warrants to purchase shares of Common Stock (the "Warrants"). All
of the shares of Common Stock that may be acquired by the Stockholders from time
to time after the date of this agreement pursuant to conversion of the Series A
Preferred Stock and exercise of the Warrants are intended by the parties to be
the only shares of capital stock of the Company subject to all of the terms and
conditions of this agreement, and are collectively referred to herein as the
"Shares."

               The Company desires to provide to the Stockholders certain rights
regarding the registration of the Shares, all upon the terms and conditions set
forth below.

               It is therefore agreed as follows:

               1.     Mandatory Registration.
                      ----------------------

               (1)   Within 90 days of the closing of the sale of the Series A
Preferred Stock and Warrants to the Stockholders (the "Private Placement
Closing"), the Company shall prepare and file with the U.S. Securities and
Exchange Commission (the "Commission") a registration statement on an
appropriate form for registering for resale by the Stockholders the Shares for
the Stockholders (or such lesser number as may be required by the Commission),
and such registration statement shall state that it also covers such
indeterminate number of additional shares of Common Stock as may become issuable
to prevent dilution resulting from stock splits or stock dividends.

               (2)    The Company shall pay all Registration Expenses (as
defined below) in connection with registration of the Registrable Securities (as
defined below) pursuant to this section 1.

               (3)    As used in this agreement (i) "Registrable Securities"
means the Shares held by the Stockholders; provided that any such Share shall
cease to be a Registrable Security when (A) a registration statement with
respect to their public sale shall have become effective under the Securities
Act, (B) they have been disposed of as permitted by, and in compliance with,
Rule 144 (or successor provision) promulgated under the Securities Act, (C) they
may be disposed of as permitted by, and in compliance with, subsection (k) of
such Rule 144 (or successor provision) or (D) they shall have ceased to be
outstanding, (iii) "Holder" means the Stockholders, and (iv) "Securities Act"
shall mean the Securities Act of 1933, or any subsequent similar federal
statute, and the rules and regulations of the Commission or any other federal
agency at the time administering the Securities Act.

               (4)   As used in this agreement, "Registration Expenses" means
all expenses incident to the Company's performance of or compliance with the
provisions of sections 1, 2 and 3 including, without limitation, all
registration, filing and National Association of Securities Dealers, Inc. fees,
all listing fees, all fees and expenses of complying with securities or blue sky
laws (including, without limitation, reasonable fees and disbursements of
counsel for the underwriter in connection with blue sky qualifications of the
Registrable Securities), all printing 
<PAGE>
 
expenses, the fees and disbursements of counsel for the Company and of its
independent public accountants, including the expenses of "comfort" letters
required by or incident to such performance and compliance, and any fees and
disbursements of underwriters customarily paid by issuers or sellers of
securities; provided, however, that Registration Expenses shall exclude, and the
Holders shall pay, underwriters fees and underwriting discounts and commissions
and transfer taxes in respect of the Registrable Securities being registered as
well as any fees and expenses of counsel or other advisors to the Holders of the
Registrable Securities.

               2. Registration Procedures. In connection with the registration
                  -----------------------
of any Registrable Securities under the Securities Act as provided in section 1,
the Company shall, within 90 days of the Private Placement Closing:

                  (1) prepare and file with the Commission the requisite
        registration statement to effect such registration and thereafter use
        its best efforts to cause such registration statement to become and
        remain effective (subject to clause (ii) below); provided, however, that
        the Company may discontinue any registration of its securities that are
        not Registrable Securities at any time prior to the effective date of
        the registration statement relating thereto;

                  (2) prepare and file with the Commission such amendments
        and supplements to such registration statement and the prospectus used
        in connection therewith as may be necessary to keep such registration
        statement effective and to comply with the provisions of the Securities
        Act with respect to the disposition of all Registrable Securities
        covered by such registration statement for such period as shall be
        required for the disposition of all of such Registrable Securities;

                  (3) furnish to the Holders such number of conformed copies
        of such registration statement and of each such amendment and supplement
        thereto (in each case including all exhibits), such number of copies of
        the prospectus contained in such registration statement (including each
        preliminary prospectus and any summary prospectus) and any other
        prospectus filed under Rule 424 under the Securities Act, in conformity
        with the requirements of the Securities Act, and such other documents,
        as the Holders may reasonably request;

                  (4) use its best efforts (x) to register or qualify all
        Registrable Securities and other securities covered by such registration
        statement under such other securities or blue sky laws of such states of
        the United States of America where an exemption is not available and as
        the Holders shall reasonably request, (y) to keep such registration or
        qualification in effect for so long as such registration statement
        remains in effect, and (z) to take any other action that may reasonably
        be necessary or advisable to enable the Holders to consummate the
        disposition in such jurisdictions of the securities to be sold by the
        Holders, except that the Company shall not for any such purpose be
        required to qualify generally to do business as a foreign corporation in
        any jurisdiction wherein it would not, but for the requirements of this
        paragraph (iv), be obligated to be so qualified or to consent to general
        service of process in any such jurisdiction;

                  (5) use its best efforts to cause all Registrable Securities
        covered by such registration statement to be registered with or approved
        by such other federal or state governmental agencies or authorities as
        may be necessary in the opinion of counsel to the Company to consummate
        the disposition of such Registrable Securities in accordance with their
        intended method of disposition;

                  (6) furnish to the Holders' underwriters, if any, (x) an
        opinion of counsel for the Company, and (y) a "comfort" letter signed by
        the independent public accountants who have certified the Company's
        financial statements included or incorporated by reference in such
        registration statement, each covering substantially the same matters
        with respect to such registration statement (and the prospectus included
        therein) and, in the case of the accountant's comfort letter, with
        respect to events subsequent to the date of such financial statements,
        as are customarily covered in opinions of issuer's counsel and in
        accountant's comfort letters delivered to the underwriters in
        underwritten public offerings of securities (and dated the dates such
        opinions and comfort letters are customarily dated);
<PAGE>
 
                    (7) notify the Holders when a prospectus relating thereto
        is required to be delivered under the Securities Act, upon discovery
        that, or upon the happening of any event as a result of which, the
        prospectus included in such registration statement, as then in effect,
        includes an untrue statement of a material fact or omits to state any
        material fact required to be stated therein or necessary to make the
        statements therein not misleading, in the light of the circumstances
        under which they were made, and at the request of the Holders promptly
        prepare and furnish to them a reasonable number of copies of a
        supplement to or an amendment of such prospectus as may be necessary so
        that, as thereafter delivered to the purchasers of such securities, such
        prospectus shall not include an untrue statement of a material fact or
        omit to state a material fact required to be stated therein or necessary
        to make the statements therein not misleading in the light of the
        circumstances under which they were made;

                    (8) otherwise use its best efforts to comply with all
        applicable rules and regulations of the Commission, and make available
        to its security holders, as soon as reasonably practicable, an earnings
        statement covering the period of at least 12 months, but not more than
        18 months, beginning with the first full calendar month after the
        effective date of such registration statement, which earnings statement
        shall satisfy the provisions of section 11(a) of the Securities Act and
        Rule 158 promulgated thereunder, and promptly furnish the same to the
        Holders; and

                    (9) provide and cause to be maintained a transfer agent
        and registrar (which, in each case, may be the Company) for all
        Registrable Securities covered by such registration statement from and
        after a date not later than the effective date of such registration.

               The Company may require the Holders to furnish the Company such
information regarding the Holders and the distribution of the Holders'
Registrable Securities as the Company may from time to time reasonably request
in writing.

               Upon receipt of any notice from the Company of the happening of
an event of the kind described in item (vii) of this section 2, the Holders will
forthwith discontinue their disposition of Registrable Securities pursuant to
the registration statement relating to such Registrable Securities until the
Holders' receipt of the copies of the supplemented or amended prospectus
contemplated by item (vii) and, if so directed by the Company, the Holders will
deliver to the Company all copies, other than permanent file copies, then in the
Holders' possession, of the prospectus relating to such Registrable Securities
current at the time of receipt of such notice.

               3.   Indemnification.
                    ---------------

               3.1  Indemnification by the Company. In the event of any
                    ------------------------------
registration statement filed pursuant to section 1, the Company shall, and
hereby does, indemnify and hold harmless each of the Holders and each of their
directors, officers, partners, agents, attorneys, representatives and affiliates
and each other individual, group, partnership, corporation, business trust,
joint stock company, trust, unincorporated association, joint venture or other
entity of whatever nature ("Person") who participates as an underwriter in the
offering or sale of such securities and each other Person, if any, who controls
any Holder or any such underwriter within the meaning of the Securities Act
(each of the foregoing, a "Holder Indemnitee"), insofar as actual and reasonable
losses, claims, damages, or liabilities (or actions or proceedings, whether
commenced or threatened, in respect thereof) primarily arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any such registration statement, any preliminary prospectus, final
prospectus, or summary prospectus contained therein, or any amendment or
supplement thereto, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein in light of the circumstances in which they were made not misleading,
and the Company shall reimburse each Holder Indemnitee for any legal or any
other fees, costs and expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; provided, that the Company shall not be liable in any such case to
the extent that any such loss, claim, damage, liability (or action or proceeding
in respect thereof) or expense arises out of or is based upon an untrue
statement or omission made in reliance upon and in conformity with information
furnished to the Company by or on behalf of a Holder or such underwriter, as the
case may be, for use in the preparation thereof; and 
<PAGE>
 
provided, further, that the Company shall not be liable to any Holder Indemnitee
--------  -------
in any such case to the extent that any such loss, claim, damage, liability (or
action or proceeding in respect thereof) or expense arises out of such Person's
failure to send or give a copy of the final prospectus, as the same may be then
supplemented or amended, to the Person asserting an untrue statement or alleged
untrue statement or omission or alleged omission at or prior to the written
confirmation of the sale of Registrable Securities to such Person if such
statement or omission was corrected in such final prospectus so long as such
final prospectus, and any amendments or supplements thereto, have been furnished
to such underwriter or any Holder, as applicable.

               3.2 Indemnification by the Holders. If any Registrable Securities
                   ------------------------------
are included in any registration statement, the Holders shall, and hereby do,
indemnify and hold harmless (in the same manner and to the same extent as set
forth in section 3.1 above) the Company, and each director and officer of the
Company, and each other Person, if any, who controls the Company within the
meaning of the Securities Act, with respect to any statement contained in, or
omission from, such registration statement, any preliminary prospectus, final
prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, if such statement or alleged statement or omission or
alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by the Holders for use in the preparation
of such registration statement, preliminary prospectus, final prospectus,
summary prospectus, amendment or supplement.

               3.3 Notice of Claims, Etc. Promptly after receipt by an
                   ---------------------
indemnified party of notice of the commencement of any action or proceeding
involving a claim referred to in sections 3.1 or 3.2, such indemnified party
will, if a claim in respect thereof is to be made against an indemnifying party,
immediately give written notice to the latter of the commencement of such
action; provided, however, that the failure of any indemnified party to give
        --------  -------
notice as provided herein shall not relieve the indemnifying party of its
indemnity obligations, except to the extent that the indemnifying party is
actually prejudiced by such failure to give notice. In case any such action is
brought against an indemnified party, unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist in respect of such claim, the indemnifying party
shall be entitled to participate in and to assume the defense thereof, jointly
with any other indemnifying party similarly notified to the extent that it may
wish, with counsel reasonably satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party for any legal or other expenses subsequently incurred by
the latter in connection with the defense thereof other than reasonable costs
related to the indemnified party's cooperation with the indemnifying party,
unless in such indemnified party's reasonable judgment a conflict of interest
between such indemnified and indemnifying parties arises in respect of such
claim after the assumption of the defense thereof. No indemnifying party shall
be liable for any settlement of any action or proceeding effected without its
written consent, which consent shall not be unreasonably withheld. No
indemnifying party shall, without the consent of the indemnified party, consent
to entry of any judgment or enter into any settlement that does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation.

               3.4 Contribution. If indemnification shall for any reason be held
                   ------------
by a court to be unavailable to an indemnified party under section 3.1 or
section 3.2 in respect of any loss, claim, damage or liability, or any action in
respect thereof, then, in lieu of the amount paid or payable under section 3.1
or section 3.2, as applicable, the indemnified party and the indemnifying party
shall contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating the same), (i) in such proportion as is appropriate to reflect the
relative fault of the Company on the one hand and the Holders on the other hand
that resulted in such loss, claim, damage or liability, or action in respect
thereof, with respect to the statements or omissions that resulted in such loss,
claim, damage or liability, or action in respect thereof, as well as any other
relevant equitable considerations or (ii) if the allocation provided by item (i)
above is not permitted by applicable law, in such proportion as shall be
appropriate to reflect the relative benefits received by the Company on the one
hand and the Holders on the other. No Person guilty of fraudulent
misrepresentation (within the meaning of the Securities Act) shall be entitled
to contribution from any Person who was not guilty of such fraudulent
misrepresentation. In addition, no Person shall be obligated to contribute
hereunder any amounts in payment for any 
<PAGE>
 
settlement of any action or claim, effected without such Person's consent, which
consent shall not be unreasonably withheld.

               3.5  Other Indemnification. Indemnification and contribution
                    ---------------------
similar to that specified in the preceding provisions of this section 3 (with
appropriate modifications) shall be given by the Company and the Holders with
respect to any required registration or other qualification of securities under
any federal or state law or regulation of any governmental authority other than
the Securities Act.
