                                   ARTICLE VII
                               REGISTRATION RIGHTS
                  SECTION 7.1 Piggy-Back Registration.
                           7.1.1.   Purchaser's Option.
                                    7.1.1.1.  Following  the initial  public
offering by the Company of any of its securities and until the second
anniversary of the date of this  Agreement,  if the Company  proposes to file a
registration  statement under the Securities Act with  respect to an  offering
by the Company for its own account of any class of security of the Company then
the Company shall in each case give written  notice of such  proposed  filing to
the  Purchaser at least thirty (30) days before the anticipated  filing  date,
and  such  notice  shall  offer  the  Purchaser  the opportunity to include in
such registration statement such number of Registrable Securities  (i.e.,
capital  stock of the  Company  purchased  by the  Purchaser hereunder and owned
by the Purchaser) as the Purchaser may request.  The Company shall use its best
efforts to cause the managing  underwriter or underwriters of a proposed
underwritten  offering  to permit  the  Purchaser  to  include  such securities
in such offering on the same terms and  conditions as the  securities of the
Company included therein.
                                    7.1.1.2.   Notwithstanding  the  foregoing,
if  the  managing  underwriter  or underwriters of such proposed underwritten
offering determine in good faith that the total amount of securities  which the
Purchaser,  the Company and any other persons or entities intend to include in
such offering is sufficiently  large to
                                      -12-
materially and adversely affect the success of such offering (including, without
limitation,  by a  significant  and adverse  decrease in the  proposed  offering
price)  then the amount of securities  to be offered  shall be reduced pro rata
with other  sellers in the offering to the extent  necessary to reduce the total
amount of securities  to be included in such offering to the amount  recommended
by such managing underwriter or underwriters.
                                    7.1.1.3 In the event the  Purchaser  elects
to include  Registrable  Securities in a  registration  under  this  Section
7.1,  the  Company  need  not  include Registrable  Securities  in  the
registration  statement  in  response  to  the Purchaser's  request  if the
Company  can  find a  purchaser,  upon  terms  and conditions  acceptable to the
Purchaser,  for the aggregate  principal amount of the Registrable  Securities
proposed by the Purchaser to be registered;  if the purchase and sale of the
Registrable  Securities proposed by the Purchaser to be registered  is not
completed  within sixty (60) days,  the Company shall not be relieved of its
obligations under this Section 7.1.
                           7.1.2.   Payment  of  Registration  Expenses.  The
Company  will  pay all  Registration Expenses in  connection  with any
registration  described  in this  Section 7.1 except for the Purchaser's pro
rata share of any underwriter's  discount for any registration in which the
Purchaser participates.
                           7.1.3.   Exception  from  Registration.
Notwithstanding  the provisions of this Section 7.1, the Company shall have no
obligation to include any Registrable  Securities in any registration  filed by
the Company if the registration form to be used by the Company  pursuant to the
Securities  Act is Form S-8 or another  form which cannot be used for the public
sale of Registrable Securities.
                           7.1.4.   Availability  of Rule 144.  Notwithstanding
anything  contained  herein to the contrary,  the  registration  rights set
forth in this  Section 7.1 shall not be available to any Registrable Securities
that are freely transferable pursuant to Rule 144(k) of the SEC under the
Securities Act.
                  SECTION 7.2  Registration Procedures.
                           7.2.1.   Registration.   Whenever   the   Purchaser
requests   that  any   Registrable Securities be registered pursuant to Section
7.1 of this Agreement,  the Company will  use its best  efforts  to  effect  the
registration  and the sale of such Registrable  Securities in accordance  with
the intended  method of  disposition thereof as quickly as practicable.
                                      -13-
                           7.2.2.   Information.   For  the  purposes  of
effecting   the   registration   of  the Registrable  Securities of the
Purchaser pursuant to Section 7.1 hereof, and for the purposes of effectuating a
public  offering of its  securities,  the Company may require the Purchaser to
furnish to the Company such  information  regarding the Purchaser, the
Registrable Securities held by the Purchaser and the proposed distribution  of
such  Securities  as  may be  required  to be  disclosed  in a registration
statement by the rules and regulations under the Securities Act or under any
other applicable securities or blue sky laws, or as may be required to effect
the registration of the Registrable Securities held by the Purchaser.
                  SECTION 7.3 Registration  Expenses.  All expenses  incident to
the  Company's  performance  of or  compliance  with this  Agreement,  including
without  limitation  all  registration  and filing  fees,  fees and  expenses of
compliance with blue sky  qualifications of the Registrable  Securities,  rating
agency  fees,  printing  expenses,  messenger  and delivery  expenses,  internal
expenses  (including,  without  limitation,  all  salaries  and  expenses of its
officers and  employees  performing  legal or accounting  duties),  the fees and
expenses  incurred  in  connection  with the  listing  of the  securities  to be
registered  and  fees and  disbursements  of  counsel  for the  Company  and all
independent  certified public accountants  (including the expenses of any annual
audit,  special audit or "cold comfort"  letters required by or incident to such
performance),  securities  acts  liability  insurance (if the Company  elects to
obtain such insurance),  the reasonable fees and expenses of any special experts
retained  in  connection  with such  registration,  fees and  expenses  of other
Persons retained by the Company,  fees and expenses of the Purchaser incurred in
connection with each registration  hereunder (but not including any underwriting
discounts or commissions attributable to the sale of the Purchaser's Registrable
Securities)  and  any  out-of-pocket  expenses  of the  Purchaser,  specifically
including  the fees of one counsel for all selling  stockholders  other than the
Company  in  such   registration   (all  such   expenses   being  herein  called
"Registration Expenses"), will be borne by the Company.
                  SECTION 7.4 Indemnification.
                           7.4.1.   Indemnification.
                                    7.4.1.1.  The Company agrees to indemnify,
to the fullest extent  permitted by law, the  Purchaser,  each of their
partners and officers,  and each Person who controls  the  Purchaser  (within
the  meaning  of  the  Securities  Act or the Securities  Exchange Act of 1934,
as amended -- the  "Securities  Exchange Act") and any investment advisor
thereof or agent therefor against all losses, claims, damages,  liabilities  and
expenses to which any such Person may become  subject under the Securities Act,
the Securities  Exchange Act, state securities or Blue Sky laws or otherwise,
insofar as such losses, claims, damages, liabilities and expenses  (or  actions
in respect  thereof)  arose out of or are based upon any untrue  or  alleged
untrue  statement
                                      -14-
of a  material  fact  contained  in  any registration statement,  prospectus or
preliminary 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 no misleading, except insofar as the same are caused by or contained in
any information with respect to the Purchaser furnished in writing to the
Company by or on behalf of the  Purchaser  expressly for  use  therein  or by
the  Purchaser's  failure  to  deliver  a  copy  of the registration  statement
or prospectus or any amendments or  supplements  thereto after the Company has
furnished the Purchaser with a sufficient number of copies of the same.  In
connection  with an  underwritten  offering,  the Company will indemnify the
underwriters thereof, their officers and directors and each person who controls
such underwriters  (within the meaning of the Securities Act or the Securities
Exchange  Act) to the same extent as provided  above with respect to the
indemnification of the Purchaser.
                                    7.4.1.2.  The Purchaser  agrees to
indemnify,  to the fullest extent  permitted by law, the Company and each of its
officers and  directors  who have signed the registration statement, each Person
who controls the Company (within the meaning of the  Securities  Act or the
Securities  Exchange  Act),  the  other  selling stockholders selling under such
registration and any agent therefor, against all losses,  claims,  damages,
liabilities  and  expenses  (or  actions  in respect thereof)  that  arose out
of or are based  upon any  untrue  or  alleged  untrue statement of a material
fact contained in any registration statement, prospectus or preliminary
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  insofar as the same are caused by or  contained  in any information
with  respect to such  Purchaser  furnished to the Company by or on behalf of
such Purchaser expressly for use therein or by the Purchaser's failure to
deliver a copy of the registration  statement or prospectus or any amendments or
supplements  thereto  to a  prospective  purchaser  after  the  Company  has
furnished  such  Purchaser  with a  sufficient  number  of  copies  of the same;
provided,  however,  that the  obligation  of the Purchaser  hereunder  shall be
limited  to an  amount  equal  to the net  proceeds  received  by the  Purchaser
pursuant  to the sale of  Registrable  Securities  as  contemplated  herein.  In
connection with an underwritten  offering,  the Purchaser shall be limited to an
amount equal to the net proceeds received by the Purchaser  pursuant to the sale
of  Registrable  Securities  as  contemplated  herein.  In  connection  with  an
underwritten  offering,  the Purchaser will indemnify the underwriters  thereof,
their  officers and  directors  and each person who controls  such  underwriters
(within the meaning of the Securities Act or the Securities Exchange Act) to the
same extent as provided above with respect to indemnification of the Company.
                                      -15-
                  7.4.2.   Conduct of Indemnification Proceedings.
                           7.4.2.1.   In  case  any  action  shall  be  brought
against  any  Person  entitled  to indemnification  hereunder (an  "Indemnified
Person"),  the Indemnified  Person shall  promptly  notify  the Person  from
whom  indemnification  is sought  (the "Indemnifying Person"), in writing, and
the Indemnifying Person shall assume the defense thereof,  including the
employment of counsel reasonably satisfactory to the Indemnified  Person and the
payment of all expenses.  The Indemnified Person shall  have  the  right to
employ  separate  counsel  in any  such  action  and participate  in the
defense  thereof,  but,  the fees and  expenses of any such counsel shall be
paid by the  Indemnifying  Person only if (i) the  Indemnifying Person shall
fail to assume the defense of such action as provided herein,  (ii) the
Indemnified  Person reasonably shall have concluded that there may be one or
more legal  defenses  available to it which are different  from or additional to
those  available to the  Indemnifying  person or other  Persons  represented  by
counsel  employed by the  Indemnifying  Person or (iii) the  Indemnified  Person
reasonably  shall have concluded that a conflict of interest  exists between the
Indemnifying  Person and the Indemnified  Person with respect to the action. The
Indemnifying  Person shall not be liable for any  settlement  of any such action
effected  without  its  consent,   but  if  settled  with  the  consent  of  the
Indemnifying  Person or if there be a final  judgment  for the  plaintiff in any
such action,  the Indemnifying  Person agrees to indemnify and hold harmless the
Indemnified  Person  from and against  any loss or  liability  by reason of such
settlement or judgment.
                           7.4.2.2.  This  Section  and  all of the
indemnification  provisions  contained  herein shall survive  termination of
this  Agreement and shall remain  operative and in full force and effect
notwithstanding any such termination.
                  SECTION  7.5 Rule  144.  If the  Company  shall  have  filed a
registration  statement  pursuant  to  the  requirements  of  Section  12 of the
Securities Exchange Act or a registration statement pursuant to the requirements
of the  Securities  Act,  the  Company  covenants  that it will file the reports
required to be filed by it under the Securities Act and Securities  Exchange Act
and the rules and  regulations  adopted by the Commission  thereunder.  Upon the
request of the  Purchaser,  the Company will deliver to the  Purchaser a written
statement as to whether it has complied with such requirements. The Company will
take such further  action as the Purchaser may  reasonably  request,  all to the
extent  required from time to time to enable the  Purchaser to sell  Registrable
Securities  without  registration under the Securities Act within the limitation
of the  exemptions  provided by (a) Rule 144 under the  Securities  Act, as such
rule may be  amended  from time to time or (b) any  similar  rule or  regulation
hereafter adopted by the Commission.
                                      -16-
                  IN WITNESS  WHEREOF,  the  parties  hereto  have  caused  this
Agreement   to  be   executed   on  their   behalf  by  their  duly   authorized
representatives, as of the day and year first above written.

         PAYMENT ON THE PRINCIPAL OF AND INTEREST ON THIS NOTE IS REQUIRED TO BE
MADE DIRECTLY TO THE REGISTERED HOLDER HEREOF WITHOUT NOTATION HEREON. IT CANNOT
BE  DETERMINED  FROM  THE  FACE  OF THIS  NOTE  WHETHER  ALL OR ANY  PART OF THE
PRINCIPAL OF OR INTEREST ON THIS NOTE HAS BEEN PAID.
         LIFE CRITICAL CARE CORPORATION (the "Company"), a Delaware corporation,
for value received,  promises to pay to the registered  holder of this note (the
"Holder") by June 30, 1997 (or earlier as herein  referred  to),  the  principal
amount of  ______________________________  ($_______)  and interest as set forth
herein.
         The  interest  hereon  shall be payable  at the  annual  rate of Twelve
Percent  (12%) per annum  (the  "Rate")  for each day from the date of this note
until the date the principal amount of this note is paid in full.
Interest hereunder shall accrue and shall be due on June 30, 1997.
         The  total  outstanding  principal,   together  with  accrued  interest
thereon, shall be payable on June 30, 1997.
         Principal of and interest on this note shall be paid to the  registered
Holder  hereof by check mailed by the Company to the address of the Holder as it
appears on the Note  Register and at the end of this note without the  necessity
of  surrendering  or presenting  this note,  and all such  payments  shall fully
discharge  the  obligation  of the Company  hereunder  to the extent  made.  The
Company and the Holder  hereof may make  provision  for the payment of principal
and interest by such other method as may be mutually agreed upon in writing.
         At the  option of the  Company  and upon  notice  to the  Holder at its
address as it appears on the Note  Register and at the end of this note,  except
as otherwise  provided herein,  this note may be redeemed by the Company in part
or in whole, less any partial payments  previously made by the Company,  if any,
at any time or from time to time. In the event the Company  redeems only part of
the note, any amount paid to the Holder shall be applied,  first, to accrued but
unpaid interest, and second, the then outstanding principal amount. In the event
the Company redeems the entire note, the redemption
price shall be equal to the outstanding  principal of the note plus accrued and
unpaid  interest to the date of the redemption.  Except for a redemption in
connection with an initial public offering by the Company as to which this
redemption notice is hereby waived, any such  redemption  shall be made upon at
least  ten (10)  days' but not more than sixty (60) days'  prior  notice to the
Holder at the address of the Holder as it appears on the Note Register and at
the end of this note. On the date designated for redemption of the whole note,
the note so called for redemption shall become and be due and payable at the
above redemption price, the interest on such notes shall cease to accrue,  and
the Holder hereof shall have no rights in respect of this note except to receive
payment of the redemption price hereof.  The Company shall be obligated to
redeem this Note within three (3) days after closing on an initial public
offering by the Company of any of its securities.
         This note shall be registered by the Company upon the initial  delivery
hereof,  in the name of the  initial  purchaser,  by  endorsement  in the  space
provided  at the end hereof and on the books to be kept for that  purpose by the
Company and,  thereafter,  this note shall be  transferable  only by  successive
endorsements  to  successive  registered  holders.  Payment of this note and the
interest  hereon shall be made only to the registered  Holder hereof on the date
such  payment is due.  The  Company  may deem and treat the person in whose name
