      1.   Grant of  Options.    American  HealthChoice,  Inc.,  a  New  York
 corporation  ("Grantor"),  hereby   grants  to   the  above-named   optionee
 ("Optionee"), a  non-qualified  stock option  (collectively,  "Options")  to
 purchase at the Option Exercise Price (set forth above) per share, until the
 Option Expiration Date, and  on the terms and  conditions set forth in  this
 agreement ("Agreement")  that  number  of  shares,  as  adjusted  as  herein
 provided (as so adjusted, "Option Shares"), of common stock ("Common Stock")
 of the  Grantor, pursuant  to the   Grantor's  2005 Stock  Option Plan  (the
 "Plan").

      2.   Vested Shares:   The  number of  Vested Shares  (disregarding  any
 resulting fractional share) as of any date is determined by multiplying  the
 Number of Option Shares by the "Vested Ratio" determined as of such date  as
 follows:

           a.   On each Measurement  Date set forth  in Column  1 below,  the
      Option shall vest and become  exercisable for the corresponding  number
      of shares of Common Stock set forth in Column 2 below if the Optionee's
      engagement with  the  Company  and/or any  Affiliated  Entity  has  not
      terminated.  The "Vested  Portion" of the Option  as of any  particular
      date shall be the cumulative total  of all shares for which the  Option
      has become exercisable as of that date.

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

           b.   Notwithstanding anything to the contrary contained herein  or
      in the Plan, in the event the Optionee's engagement with the Company is
      terminated by the Company   within one (1)  year following a Change  in
      Control for  any  reason other  than  Cause,   then  Vesting  shall  be
      determined pursuant to the Plan.

           c.   Any cessation of Services by the  Optionee other than upon  a
      Change of  Control   shall  terminate  the vesting  schedule,  and  any
      options that have theretofore become vested shall be exercisable by the
      Optionee.

      3.   Exercise of  Options.    Other  terms,  times  and  conditions  of
 exercise of the Options are as follows:

           a.   Prior to the Expiration Date,  vested Options shall be  fully
      exercisable in  whole or  in part  for a  number of  shares up  to  the
      aggregate number of  all vested Option  Shares.  The  Options shall  be
      exercised by completing the exercise form attached hereto as Exhibit A.

           b.   Upon the death or Disability of the Optionee, the Optionee or
      the  personal  representative  of  the  Optionee,  as  applicable,  may
      exercise the Options to  the extent not  previously exercised (and,  in
      the case of death, to the extent the Options could have been  exercised
      by the Optionee on the date of death) subject to the terms set forth in
      this Agreement,  until  their  termination as  provided  by  Section  2
      hereof.

           c.   The Options shall be exercised by written notice directed  to
      the Grantor.  Such written notice shall be accompanied by full  payment
      in cash  for the  number of  Option Shares  specified in  such  written
      notice or by such other method authorized by the Plan.

           d.   Subject to the terms  of this Agreement  or the Plan,  vested
      Options may be exercised  at any time and  without regard to any  other
      option to purchase stock of the Company held by the Optionee.

           e.   In the  event  the outstanding  shares  of Common  Stock  are
      increased or decreased  or changed into  or exchanged  for a  different
      number or kind of shares or other  securities of the Company or of  any
      other  corporation   by  reason   of  any   merger,  sale   of   stock,
      consolidation, liquidation,  recapitalization, reclassification,  stock
      split up, combination of shares, stock dividend, or transaction  having
      similar effect, the total number of shares subject to this Option shall
      be proportionately and appropriately  adjusted.  Any fractional  shares
      resulting from  any of  the foregoing  adjustments under  this  section
      shall be disregarded and eliminated.

      4.   Nontransferability.  The  Options are not  transferable except  by
 will or  by the  laws of  descent  and  distribution.   The Options  may  be
 exercised during the lifetime of the Optionee only by the Optionee.

      5.   Limitation of Rights.   The  Optionee shall  have no  rights as  a
 stockholder with  respect to  the Option  Shares  until the  Optionee  shall
 become the holder of record of such Option Shares.

      6.   Successors.  This Agreement shall be binding upon any successor of
 the Grantor and Optionee, in accordance with the terms of this Agreement and
 the Plan.

      7.   Plan.  The Option  is subject to all  terms and provisions of  the
 Plan, and  in  the  event of  any  discrepancy  between the  Plan  and  this
 Agreement, the Plan shall control.

                           [Signature Page Follows]

<PAGE>

failure on the part of the Payee in exercising any rights or remedies hereunder
will not operate as a waiver of such rights, and further agrees that any
payments and prepayments received hereunder will be applied first to Costs, then
to interest and the balance to principal. The Payee shall not by any act, delay,
omission or otherwise be deemed to have waived any of its rights or remedies,
and no waiver of any kind shall be valid unless in writing and signed by the
party or parties waiving such rights or remedies. All payments under this Note
shall be made without counterclaim, offset or defense of any kind.

         This Note will be registered on the books of the Company or its agent
as to principal and interest. This Note applies to, inures to the benefit of,
and binds the successors and assigns of the parties hereto; provided however
that the Company shall not assign this Note without the prior written consent of
the Payee. Any transfer of this Note will be effected only by surrender of this
Note to the Company and reissuance of a new note to the transferee. The Payee
and any subsequent holder of this Note receives this Note subject to the
foregoing terms and conditions, and agrees to comply with the foregoing terms
and conditions for the benefit of the Company and any other Payees.

         Any notice required or permitted under this Note shall be in writing
and shall be deemed to have been given on the date of delivery, if personally
delivered to the party to whom notice is to be given, or on the third business
day after mailing, if mailed to the party to whom notice is to be given, by
certified mail, return receipt requested, postage prepaid, and addressed as
follows:

         if to the Company, at

                  Incentra Solutions, Inc.
                  1140 Pearl Street
                  Boulder, CO 80302
                  Attn:  Chief Executive Officer

and, if to the holder, at the most recent address provided to the Company by the
holder for such purpose; or, in each case, to the most recent address, specified
by written notice, given to the sender pursuant to this paragraph.

         Without limiting any of Payee's rights under this Note, Payee shall
have the right, which right may be exercised at Payee's sole and absolute
discretion, at any time from the end of each calendar quarter immediately
preceding a Payment Due Date until and including one (1) day prior to such
Payment Due Date (each such period, an "Exercise Period"), to convert (the
"Conversion") all or any portion of the principal and/or accrued interest due
under this Note on such Payment Due Date into such number of fully paid and
nonassessable shares of the common stock, par value $.001 per share, of the
Company (the "Company Common Stock"), as shall be provided herein. For purposes
of this Note, the price at which each share of Company Common Stock may be
acquired upon any Conversion shall be equal to the greater of (i) $0.40, or (ii)
seventy percent (70%) of the average closing price of Purchaser Common Stock, as
reported on Bloomberg L.P. on the Principal Market, for the ten (10) consecutive
trading days ending on and including the last day of the calendar quarter
immediately preceding the Payment Due Date on which the payment that is being
converted is due (the "Conversion Price"). Payee may exercise the Conversion
right hereunder as to any payment of principal and/or interest that will become

                                       3
<PAGE>

due on a Payment Date by giving written notice (the "Conversion Notice") to the
Company of the exercise of such right at any time during the applicable Exercise
Period and stating the name or names in which the stock certificate or stock
certificates for the shares of Company Common Stock are to be issued and the
address to which such certificates shall be delivered. If prepayment of
principal and/or interest is permitted under this Note, then the Company shall
provide Payee at least ten (10) days' advance written notice (each, a
"Prepayment Notice") of any proposed prepayment (each, a "Proposed Prepayment")
specifying the date of prepayment (each, a "Prepayment Date") and the amounts
that are proposed to be prepaid. In addition to the conversion rights set forth
above, the Payee shall have the right, which right may be exercised at Payee's
sole and absolute discretion, to convert (a "Prepayment Conversion") all or any
portion of such Proposed Prepayment amount to shares of the Company Common Stock
at a conversion price equal to the greater of (i) $0.40, or (ii) seventy percent
(70%) of the average closing price of Purchaser Common Stock, as reported on
Bloomberg L.P. on the Principal Market, for the ten (10) consecutive trading
days ending on and including the date on which the Prepayment Notice is required
to be given to Payee hereunder (the "Prepayment Conversion Price"). Payee may
exercise the Prepayment Conversion right hereunder as to any Proposed Prepayment
by giving written notice (the "Prepayment Conversion Notice") to the Company of
the exercise of such right at any time during the ten (10) day period after the
date on which Payee receives the Prepayment Notice (the "Prepayment Conversion
Exercise Period") and stating the name or names in which the stock certificate
or stock certificates for the shares of Company Common Stock are to be issued
and the address to which such certificates shall be delivered. The number of
shares of Company Common Stock that shall be issuable upon conversion of the
Note shall equal the amount of principal and/or interest requested by Payee to
be converted (the "Conversion Amount") divided by the Conversion Price (or the
Prepayment Conversion Price, as applicable) in effect on the date the Conversion
Notice (or the Prepayment Conversion Notice, as applicable) is given (the
"Conversion Date"). Within ten (10) business days after the Conversion Date, the
Company shall issue and deliver by hand against a signed receipt therefor or by
United States registered mail, return receipt requested, to the address
designated in the Conversion Notice (or the Prepayment Conversion Notice, as
applicable), a stock certificate or stock certificates of the Company
representing the number of shares of Company Common Stock to which Payee is
entitled and, in exchange for this Note, an executed replacement Convertible
Promissory Note representing the balance of the Note not converted into shares
of Company Common Stock. Any Conversion of principal hereunder shall be applied
to the remaining installments of principal in the inverse order of their
maturities, and the payment schedule of the replacement Convertible Promissory
Note shall reflect such application. In the case of any capital reorganization,
reclassification or recapitalization of the Company Common Stock, then the
conversion privilege in effect immediately before such action shall be adjusted
so that the Payee may receive the kind and amount of shares of stock and other
securities and property receivable upon such reorganization, reclassification or
recapitalization by a holder of the number of shares of Company Common Stock
into which this Note could have been converted immediately prior to such
reorganization, reclassification or recapitalization; and any such resulting or
surviving corporation shall expressly assume the obligation to deliver, upon the
exercise of the conversion privilege, such shares, securities or property as the
Payee may be entitled to and to make provisions for the protection of the
conversion rights as herein provided. In case securities or property other than
shares of Company Common Stock shall be issuable or deliverable upon conversion
as aforesaid, then all references in this Note to the Company

                                       4
<PAGE>

Common Stock shall be deemed to apply, so far as appropriate and as nearly as
practicable, to such other securities or property. The Company will not, by
amendment of its Organizational Documents or through any reorganization,
transfer of assets, 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 hereunder by the Company but will
at all times in good faith assist in the carrying out of all the provisions of
this Note and in the taking of all such action as may be necessary or
appropriate in order to protect the conversion rights of the Payee against
impairment. No fractional shares of the Company Common Stock are to be issued
upon the Conversion (or the Prepayment Conversion, as applicable) of this Note.
In lieu of delivering any fractional shares to which the Payee would otherwise
be entitled, the number of shares of Company Common Stock shall be rounded to
the nearest whole number. As soon as practicable after the date hereof, the
Company shall take all necessary actions, including but not limited to, amending
the Company's articles of incorporation, to ensure that the Company will have
sufficient shares of duly authorized but unissued Company Common Stock reserved
to issue upon conversion of this Note or any part thereof. Notwithstanding
anything contained herein, any portion of the payment which is due on a Payment
Due Date or a Prepayment Date, as applicable, that is not converted by Payee
pursuant this provision shall be paid in full to Payee on such Payment Due Date
or Prepayment Date, as applicable.

         This Note is made under and shall be governed by and construed in
accordance with the internal laws of, and enforced by the courts located within,
the State of Colorado.

          IN WITNESS WHEREOF, the Company has executed this Note under seal as
of the date first written above.
