                                OPTION AGREEMENT

     THIS OPTION AGREEMENT,  effective as of the 7th day of March,  2000, by and
between Simione Central Holdings,  Inc., a Delaware corporation (the "Company"),
and Mestek, Inc., a Pennsylvania corporation (the "Optionee").

                                   WITNESSETH:

     WHEREAS,  the  Company  has  entered  into a Second  Amended  and  Restated
Agreement and Plan of Merger and Investment  Agreement by and among the Company,
Optionee,  a wholly-owned  subsidiary of Optionee and certain additional parties
(the "Merger Agreement").

     WHEREAS,  in connection  with the Merger  Agreement the Company has sold to
Optionee, and Optionee has purchased from the Company, certain securities of the
Company as more particularly described in the Merger Agreement.

     WHEREAS,  pursuant to and in  accordance  with the terms and  conditions of
Section 3.3 of the Merger  Agreement,  the Company and Optionee  desire to enter
into this  Agreement with respect to an option on certain shares of common stock
of the  Company  (the  "Common  Stock")  in order to set  forth  the  terms  and
conditions  upon which such option shall be granted by the Company and exercised
by Optionee.

     NOW,  THEREFORE,  in consideration of the mutual benefits to each party, it
is agreed as follows:

     1. Grant of Option.  Subject to the terms and  conditions set forth herein,
Optionee  shall have the right to  purchase  a number of shares of Common  Stock
equal  to  0.8518518  (the  "Ratio")  multiplied  by the  number  of  "Scheduled
Option/Warrant  Shares" (as defined below); such shares hereinafter are referred
to as the "Option  Shares,"  and this option  hereinafter  is referred to as the
"Option".  "Scheduled  Option/Warrant Shares" means those shares of Common Stock
which   may  be,   subject   to   various   agreements   evidencing   "Scheduled
Options/Warrants"  (as defined  below),  purchased by "Scheduled  Option/Warrant


                                       1
<PAGE>


Holders" (as defined below), as set forth in Schedule A. The aggregate number of
Scheduled Option/Warrant Shares shall be equal to the aggregate number of shares
subject to Scheduled  Option/Warrants.  "Scheduled  Option/Warrants"  shall mean
those options and warrants set forth on Schedule A which have been, on or before
the  date  hereof,  granted  to  Scheduled  Option/Warrant  Holders.  "Scheduled
Option/Warrant  Holder(s)"  shall mean those  individuals  who have been granted
Scheduled  Option/Warrants  on or before the date hereof. The Company represents
and warrants that Schedule A sets forth all outstanding  options and warrants of
the Company as of the date hereof. Notwithstanding anything in this Agreement to
the contrary,  Scheduled  Option/Warrant  Shares shall also be deemed to include
any shares of Common Stock issuable as of the date hereof in connection with any
outstanding  rights to receive  shares of Common  Stock from or  relating to the
Company's 1997 reverse stock split.

    2.    Exercise   of   Option.

          (a)  Vesting  of  Option   Contingent   Upon   Exercise  of  Scheduled
Options/Warrants and Purchase of Scheduled  Option/Warrant  Shares.  Immediately
upon the exercise  after the date hereof of any  Scheduled  Option/Warrants  and
purchase of Scheduled Option/Warrant Shares by a Scheduled Option/Warrant Holder
(a "Vesting  Event"),  the Option shall become  exercisable  with respect to the
number of Option Shares equal to the Ratio multiplied by the number of Scheduled
Option/Warrant  Shares  purchased by such Scheduled  Option/Warrant  Holder (the
"Vesting  Event  Number")  at  the  same  price  per  share  as  such  Scheduled
Option/Warrant  Shares were purchased (the "Vesting Event Price").  Prior to the
occurrence of a Vesting Event,  no portion of the Option shall be exercisable by
Optionee, and Option Shares shall become subject to purchase under the terms and
provisions  of the Option only to the extent that  Vesting  Events  occur as set
forth in the  preceding  sentence.

          (b) Notification of Exercise of Scheduled Options/Warrants.  Each time
any Vesting Event occurs, the Company shall promptly, and in no event later than
ten (10) days following such Vesting Event, notify Optionee of the Vesting Event
Number and the Vesting Event Price with respect to such Vesting  Event,  and the
date on which such Vesting Event occurred.

          (c) Method of Exercise and Payment.  When Option Shares become subject
to purchase  upon the  occurrence  of a Vesting  Event,  the Option Shares which
Optionee  desires to purchase  may be exercised  by  Optionee's  delivery to the
Secretary  of the  Company of one or more  Notices of  Exercise,  in the form of
Schedule  B, each  accompanied  by  payment  in full of the  "Option  Price" (as
defined below).  Such delivery must be made within one hundred eighty (180) days
of the date on which  Optionee  received  notice of the  Vesting  Event from the
Company.  The "Option  Price"  shall be an amount  equal to the number of Option
Shares  purchased  multiplied by the Vesting  Event Price,  and shall be paid by
cashier's  check  payable to the  Company  or by wire  transfer  of  immediately
available  funds to an account  designated  from time to time by the Company for
such purpose.

     3.  Termination  of Option  and  Option  Rights.  The  Option  shall not be
exercisable either in whole or in part 180 days after the date on which Optionee
receives notice from the Company that all Scheduled Options/Warrants have either
expired  and  are  no  longer   exercisable,   or  have  been  fully  exercised.
Furthermore,  portions of the Option shall terminate (and Option Shares shall no
longer be subject to purchase by Optionee) as follows:





                                       2
<PAGE>

         (a) Partial Termination Upon Failure to Exercise.  Upon the occurrence
of a Vesting  Event,  any Option  Shares  which  become  subject to  purchase by
Optionee in accordance with the provisions of Section 2 above and which Optionee
fails to  purchase  within 180 days of the date of receipt of notice by Optionee
of such Vesting  Event,  shall cease to be subject to purchase under the Option,
and such  portion  of the Option  shall no longer be  exercisable.

          (b) Partial  Termination  Upon  Termination  of  Underlying  Scheduled
Option/Warrants.  To the extent that any Scheduled  Option/Warrant Shares are no
longer  subject to  purchase  by a  Scheduled  Option/Warrant  Holder due to the
expiration or termination of all or a portion of a Scheduled Option/Warrant,  or
for any other  reason,  any Option  Shares  which could have  become  subject to
purchase by Optionee in accordance  with the  provisions of Section 2 above with
respect to a Vesting Event involving such Scheduled  Option/Warrant Shares shall
cease to be subject to purchase under the Option, and such portion of the Option
shall  no  longer  be  exercisable.

     4. Notification of Change in Control Transaction.  In the event the Company
proposes  or becomes  aware of a "Change in Control  Transaction,"  the  Company
shall promptly,  and in no event later than ten (10) days following the proposal
of such  Change in Control  Transaction,  notify the  Optionee of such Change in
Control Transaction.  "Change in Control Transaction" shall mean any transaction
wherein the Company (i) consolidates  with or merges into any other  corporation
and is not the  continuing or surviving  corporation  of such  consolidation  or
merger,  or (ii) permits any other corporation to consolidate with or merge into
the Company and the Company is the continuing or surviving  corporation  but, in
connection with such  consolidation or merger,  the Common Stock is changed into
or exchanged for stock or other  securities of any other  corporation or cash or
any other assets,  or (iii) transfers all or substantially all of its properties
and assets to any other corporation, or (iv) effects a capital reorganization or
reclassification  of the capital stock of the Company in such a way that holders
of Common Stock shall be entitled to receive stock,  securities,  cash or assets
with respect to or in exchange for Common Stock.

     5.  Registration  Rights.  The Option Shares shall be subject to, and shall
deemed to be  "Registrable  Shares"  within the meaning  of,  Section 4.1 of the
Merger  Agreement  relating to registration  rights.

     6. Reservation of Shares;  Validity of Issuance.  The Company covenants and
agrees that it shall  reserve for issuance  upon the exercise of this Option and
keep available out of its authorized but unissued  Common Stock,  such number of
shares  of  Common  Stock  for  which  this  Option  shall  from time to time be
exercisable. The Company represents and warrants that all shares issued upon the
exercise of this Option will, upon issuance, be fully paid and nonassessable and
be free from all liens and charges in respect of their issuance,  with all taxes
payable by the Company with respect to such issuance  fully paid by the Company.

     7. Adjustments for Stock Splits and Combinations.  If presently outstanding
shares of Common Stock shall be subdivided into a greater number of shares, or a
dividend  in Common  Stock or other  securities  of the Company  convertible  or
exchangeable  into shares of Common  Stock (in which  latter event the number of


                                       3
<PAGE>


shares  of  Common  Stock  issuable  upon the  conversion  or  exchange  of such
securities shall be deemed to have been  distributed),  shall be paid in respect
to the Common  Stock (but in all cases  excluding  any such  events if  material
value is paid to the Company in connection therewith),  (a) the number of shares
of Common Stock which may be acquired by the Optionee  upon the exercise of this
Option shall,  simultaneously  with the  effectiveness  of such  subdivision  or
immediately  after  the  record  date  of  such  dividend,   be  proportionately
increased, and (b) the Option Price shall be adjusted, to the same extent and in
the same manner that the number of shares subject to, and the exercise price of,
the Scheduled  Options/Warrants  are increased or adjusted,  as the case may be.
Conversely,  if the outstanding  shares of Common Stock shall be combined into a
smaller  number of  shares,  the number of shares of Common  Stock  which may be
acquired by the Optionee upon the exercise of this Option shall,  simultaneously
with the effectiveness of such combination,  be proportionately reduced, and the
Option Price shall be adjusted in accordance herewith.

     8. Agreement of Optionee.  Optionee hereby agrees to hold all of the Option
Shares acquired by Optionee  pursuant to Optionee's  exercise of this Option for
investment purposes and not with a view to resale or distribution thereof to the
public.  Optionee  hereby  agrees  to  execute  such  documents  as the Board of
Directors  of the  Company  may  require  with  respect  to  state  and  federal
securities  laws and any  restrictions  on the resale of the Option Shares which
may be applicable.

     9. No  Impairment.  The Company  will not,  by  amendment  of its  Restated
Articles  or through  any  reorganization,  transfer  of assets,  consolidation,
merger, dissolution,  issue or sale of securities or any other voluntary action,
avoid or seek to avoid the  observance or  performance of any of the terms to be
observed or performed by the Company under this Option, but will at all times in
good faith assist in the carrying out of all the  provisions  of this Option and
in the taking of all such action as may be necessary or  appropriate in order to
protect  the  rights  of  Optionee.  The  Company  shall  not  amend,  adjust or
substitute any of the Scheduled  Options/Warrants  in a manner that would impair
the rights of Optionee  under this Option  Agreement  without the prior  written
consent  of  Optionee.

     10. No Voting Rights.  This Option shall not entitle Optionee to any voting
rights or other  rights as a  stockholder  of the  Company,  and no  dividend or
interest  shall be payable or accrue in respect of this  Option or the  interest
represented by or the shares purchasable under this Option until and unless, and
except  to  the  extent  that,  this  Option  shall  be  exercised.

     11.  Stock  Certificates.  The  issuance  of  stock  certificates  upon the
exercise of this Option  shall be made  without  charge to Optionee  for any tax
(other than (i) income taxes and (ii) transfer taxes  resulting from issuance of
stock  certificates  to a person other than Optionee) in respect of the issue of
such stock.  Optionee shall for all purposes be deemed to have become the holder
of record of the shares issued upon exercise of this Option on the date both the
Option  Price  and  the  Notice  of  Exercise  are  delivered  to  the  Company,
irrespective of the date of delivery of the certificate for such shares,  except
that,  if the date the Notice of Exercise and the Option Price are  delivered to
the  Company is a date the  Company is closed for  business,  Optionee  shall be
deemed to have  become the holder of such shares at the close of business on the
next  succeeding  date  on  which  the  Company  is  open  for  business.   Such
certificates  evidencing  the  shares of Common  Stock  issued  pursuant  to the
exercise of this Option shall bear  restrictive  legends similar to those at the
head of this  Agreement and any other legend  required  pursuant to any federal,
state,  local or foreign law  governing  the Common  Stock.
