corporation (the "Company"),  and Doctors Choice,  Inc., a Delaware  corporation
(the "Consultant").

WHEREAS, the Company desires to obtain the benefit of the Consultant's knowledge
and experience by retaining the Consultant, and the Consultant desires to accept
such position, for the term and upon the other conditions hereinafter set forth.

NOW, THEREFORE, in consideration of the mutual promises and agreements contained
herein,  the  adequacy and  sufficiency  of which are hereby  acknowledged,  the
Company and the Consultant hereby agree as follows:

1. EFFECTIVE DATE AND CONSULTING  TERM: This Agreement shall be effective on the
date first written above (the "Effective  Date").  The Consultant shall commence
rendering his consulting  services  hereunder on June 1, 2003 and shall continue
to render such  services  for a two (2) year term  expiring on May 31, 2005 (the
"Term"),  unless the Term shall be earlier terminated in accordance with Section
7 or 8 below. Each twelve month period during the Term that commences on May 1st
and ends on April 30th of the  following  year shall be  referred to herein as a
"Year".

2. POSITION AND DUTIES: During the Term, the Consultant shall, at the request of
the  Company's  Chairman  of the  Board,  Chief  Executive  Officer  or Board of
Directors,  render  consulting  services to NEW YORK  MEDICAL,  INC., a New York
corporation  ("NYMI") and an indirect  subsidiary  of the  Company,  relating to
strategic planning, product development and general business matters.

3.  LOCATION:  The  Consultant's  consulting  services  shall be rendered at the
principal executive offices of NYMI or at any other mutually agreeable location.

hereunder.

4. COMPENSATION: The Consultant shall be compensated by the Company as follows:

          a. Consulting  Fees:  During the Term, the Consultant will be paid the
     sum of Two Hundred and Forty Thousand Hundred Thousand  ($240,000)  Dollars
     as a consulting fee, payable in monthly installments at the rate of $10,000
     each (the "Base Fee. In addition to the Base Fee, the  Consultant  shall be
     entitled  to receive a success  fee (the  "Bonus  Fee")  equal to 3% of any
     increase  in  annual  net sales of NYMI for each  Year  during  the Term in
     excess of Twenty Million  ($20,000,000)  Dollars (the "Sales Base"), to the
     extent  that such  increase in annual net sales of NYMI over the Sales Base
     shall be directly or indirectly  attributable  to the efforts of Consultant
     and/or its principal,  Kenneth Orr ("Orr").  Notwithstanding the foregoing,
     the Bonus  Fee  payable  for any Year  during  the Term of this  Consulting
     Agreement  shall be capped at  $150,000,  irrespective  of such  annual net
     sales in excess of the Sales Base  attributable  to the  efforts of Kenneth

     payable monthly in equal  installments of $10,000 each. Any Bonus Fee shall
     be  payable  by the  Company,  not later than 30 days after the end of each
     Year during the Term of this Consulting Agreement.

          b.  Expenses:  During  the  Term,  the  Company  shall  reimburse  the
     Consultant for all business expenses  reasonably incurred by the Consultant
     in the performance of its consulting services hereunder as requested by the
     Company's  Chairman  of the  Board,  Chief  Executive  Officer  or Board of
     Directors,  upon submission to the Company of appropriate  documentation in
     respect of such expenses and approval by the Chief Executive Officer, which
     shall not be unreasonably withheld.

          c. Benefits:  During the Term, the Consultant shall not be entitled to
     any employee benefits (e.g., sick leave, severance or 401(k) participation)
     from the  Company.  However,  the Company  will  reimburse  Consultant  One
     Thousand  Two  Hundred and Fifty  ($1,250.00)  Dollars per month for health
     insurance provided to Orr.

<PAGE>

5.  INDEPENDENT  CONTRACTOR:  During  the  Term,  the  Consultant  shall  be  an
independent contractor and not an employee of the Company or NYMI and may render
similar  services to other  clients  provided said services do not conflict with
the  Company's  business  interests.   Accordingly,   the  Consultant  shall  be
responsible  for  payment  of all taxes for  remuneration  received  under  this
Agreement,  including  Federal  and  State  income  tax,  Social  Security  tax,
Unemployment  Insurance  tax,  and any other taxes or business  license  fees as
required.

6. THIS SECTION HAS BEEN INTENTIONALLY DELETED.

7.  VOLUNTARY   TERMINATION:   The  Consultant  may  voluntarily  terminate  its
consultancy  for any reason  upon  providing  the  Company  with 30 days'  prior
written notice. In the event Consultant  voluntarily  terminates its consultancy
with the Company,  the Consultant shall be entitled to no compensation  from the
Company other than in respect of (x) any monthly  installment of consulting fees
earned but not yet paid as of the effective date of his  termination and (y) the
reimbursement of his expenses in accordance with Section 4(b).

8. TERMINATION BY THE COMPANY: The Consultant's consultancy may be terminated by
the  Company  in the event of the death or  disability  of Kenneth A. Orr or for
cause (as  defined  below).  Upon any  termination  under  this  Section  8, the
Consultant  shall be entitled to no compensation  from the Company other than in
respect of (x) any monthly  installment  of  consulting  fees earned but not yet
paid as of the effective date of his  termination and (y) the  reimbursement  of
Consultant's  expenses in  accordance  with Section 4(b) above.  For purposes of
this Agreement, "disability" means Orr's inability to perform services on behalf
of the Consultant for any  consecutive  120-day period as a result of a physical
and/or mental impairment.

     For  purposes of this  Consulting  Agreement,  the term "for cause" means a
termination  of the  Consultant's  consultancy  by the  Company  for  any of the
following reasons: (i) the Consultant's willful and continued refusal to perform
any duty  reasonably  assigned to him in accordance  with the provisions of this
Agreement;  (ii)  any  breach  of this  Agreement  by the  Consultant,  which if
curable,  is not cured within 10 days following  written notice from the Company
to the  Consultant  of  such  breach;  (iii)  the  Company's  inability  to have
consummated one or more financings by October 17, 2003 in amounts  sufficient to
enable the  Company to satisfy  in full the  "Payment  Events"  (as that term is
defined in that certain Closing Agreement,  dated of even date herewith,  by and
among the Company,  Redwood  Investments  Associates,  L.P., Lifetime Healthcare
Services,  Inc., Dr. Jonathan Landow,  Tracy Landow, the Rubin Irrevocable Stock
Trust and Robert M. Rubin (the "Closing  Agreement"),  (iv) the  Consultant's or
Orr's  conviction  (including  any plea of  guilty or nolo  contendere)  for any
criminal  act which  impairs the  Consultant's  or Orr's  ability to perform its
duties under this Agreement;  or (v) Kenneth Orr becoming an officer,  director,
employee  or agent of any  corporation,  person,  firm or  entity,  which in the
reasonable  determination  of a majority of the full membership of the Company's
Board of Directors results in, or is likely to result in, a conflict of interest
with the Consultant's position as a Consultant to the Company.

9.  NON-SOLICITATION:  During the period from the Effective Date through the end
of the Term and for a twelve month period  thereafter,  the Consultant will not,
directly or  indirectly,  recruit,  induce or otherwise  attempt to persuade any
person who is now, or who subsequently becomes an employee, sales representative
or consultant of the Company to terminate his, her or its relationship  with the
Company.

10. CONFIDENTIALITY:  The Consultant shall not, commencing on the Effective Date
and at all times thereafter,  directly or indirectly  communicate or divulge to,
or use for the  Consultant's own benefit or for the benefit of any other person,
or  entity,  any  of  the  trade  secrets,  proprietary  data  and  confidential
information of the Company,  NYMI or any other direct or indirect  subsidiary of
the Company (including, without limitation,  nonpublic information pertaining to
or derived from (i) meetings or  deliberations  of the Company's or NYMI's Board
of Directors (or any committee thereof) and (ii) discussions with any officer or
employee  or former  officer or  employee of the Company or any of its direct or
indirect subsidiaries,  member or former member of the Board of Directors of the
Company or any of its direct or indirect subsidiaries,  or any current of former
agent or attorney of the Company or any of its direct or indirect  subsidiaries,
communicated to or otherwise learned or acquired by the Consultant in the course
of his service hereunder or in the course of his service hereunder.

Company hereby knowingly and willingly waive their respective rights to have any
such disputes or claims tried by a judge or jury. Notwithstanding the foregoing,
this arbitration provision shall not apply to any disputes or claims relating to
or arising out of (i) the actual or alleged  misuse or  misappropriation  of the
Company's  property,  including,  but not  limited  to,  its  trade  secrets  or
