                           ADDITIONAL INVESTMENT RIGHT

Additional Investment Right No. [  ]                  Dated: November 24, 2003


         ICAD, INC., a Delaware  corporation  (the "Company"),  hereby certifies
that,  for value  received,  [Name of Holder]  or its  registered  assigns  (the
"Holder"),  is  entitled  to  purchase  from the Company up to a total of [ ]/1/
shares of common stock,  $0.01 par value per share (the "Common Stock"),  of the
Company (each such share,  an "Additional  Investment  Right Share" and all such
shares, the "Additional  Investment Right Shares") at an exercise price equal to
$5.00 per share (as  adjusted  from time to time as  provided  in Section 9, the
"Exercise  Price"),  at any time and from  time to time  from and after the date
hereof  and  through  and  including  the  earlier of (i) the 30th  Trading  Day
following the Effective Date and (ii) the second  anniversary of the date hereof
(the "Expiration Date"), and subject to the following terms and conditions. This
Additional  Investment Right (this  "Additional  Investment  Right") is one of a
series of similar  additional  investment rights issued pursuant to that certain
Securities  Purchase  Agreement,  dated as of the date hereof,  by and among the
Company and the Purchasers  identified therein (the "Purchase  Agreement").  All
such additional investment rights are referred to herein,  collectively,  as the
"Additional Investment Rights."

         1.  Definitions.  In addition to the terms  defined  elsewhere  in this
Additional  Investment  Right,  capitalized terms that are not otherwise defined
herein have the meanings given to such terms in the Purchase Agreement.

- -------------------
/1/ 25% of Common Stock purchased.





         2.  Registration  of  Additional  Investment  Right.  The Company shall
register this Additional  Investment Right, upon records to be maintained by the
Company for that purpose (the "Additional  Investment Right  Register"),  in the
name of the record  Holder  hereof  from time to time.  The Company may deem and
treat the registered Holder of this Additional  Investment Right as the absolute
owner hereof for the purpose of any exercise  hereof or any  distribution to the
Holder, and for all other purposes, absent actual notice to the contrary.

         3. Registration of Transfers. The Company shall register the assignment
and  transfer  of  any  portion  of  this  Additional  Investment  Right  in the
Additional  Investment  Right  Register,   upon  surrender  of  this  Additional
Investment Right, with the Form of Assignment attached hereto duly completed and
signed, to the Transfer Agent or to the Company at its address specified herein.
Upon any such  registration or transfer,  a new additional  investment  right to
purchase Common Stock, in substantially  the form of this Additional  Investment
Right (any such new additional  investment  right, a "New Additional  Investment
Right"),   evidencing  the  portion  of  this  Additional  Investment  Right  so
transferred  shall be issued to the transferee  and a New Additional  Investment
Right evidencing the remaining  portion of this Additional  Investment Right not
so  transferred,  if any,  shall  be  issued  to the  transferring  Holder.  The
acceptance of the New  Additional  Investment  Right by the  transferee  thereof
shall be deemed  the  acceptance  by such  transferee  of all of the  rights and
obligations of a holder of an Additional Investment Right.

         4. Exercise and Duration of Additional Investment Right.

              (a) This Additional  Investment  Right shall be exercisable by the
registered  Holder at any time and from time to time on or after the date hereof
to and including the  Expiration  Date. At 6:30 P.M.,  New York City time on the
Expiration  Date, the portion of this Additional  Investment Right not exercised
prior thereto shall be and become void and of no value.

              (b) The Holder may exercise this  Additional  Investment  Right by
delivering to the Company (i) an exercise  notice,  in the form attached  hereto
(the  "Exercise  Notice"),  appropriately  completed  and duly signed,  and (ii)
payment of the  Exercise  Price for the number of  Additional  Investment  Right
Shares as to which this Additional  Investment  Right is being exercised  (which
may take the form of a  "cashless  exercise"  if so  indicated  in the  Exercise
Notice and if a  "cashless  exercise"  may occur at such time  pursuant  to this
Section 10 below),  and the date such items are  delivered  to the  Company  (as
determined  in  accordance  with the notice  provisions  hereof) is an "Exercise
Date." The Holder  shall not be  required  to deliver  the  original  Additional
Investment  Right  in order to  effect  an  exercise  hereunder.  Execution  and
delivery of the Exercise  Notice shall have the same effect as  cancellation  of
the  original  Additional  Investment  Right and  issuance  of a New  Additional
Investment  Right  evidencing  the right to  purchase  the  remaining  number of
Additional Investment Right Shares.

         5. Delivery of Additional Investment Right Shares.

              (a) Upon exercise of this Additional Investment Right, the Company
shall promptly (but in no event later than three Trading Days after the Exercise
Date)  issue or cause to be  issued  and  cause to be  delivered  to or upon the
written  order  of the  Holder  and in such  name or  names  as the  Holder  may
designate,  a certificate  for the Additional  Investment  Right Shares issuable
upon such exercise,  free of restrictive legends unless a registration statement
covering  the resale of the  Additional  Investment  Right Shares and naming the

                                       2


Holder  as a  selling  stockholder  thereunder  is not  then  effective  and the
Additional  Investment Right Shares are not freely transferable pursuant to Rule
144(k) under the Securities Act. The Holder,  or any Person so designated by the
Holder to receive  Additional  Investment Right Shares,  shall be deemed to have
become  holder of record of such  Additional  Investment  Right Shares as of the
Exercise  Date.  The Company  shall,  upon  request of the Holder,  use its best
efforts to deliver Additional  Investment Right Shares hereunder  electronically
through  the  Depository  Trust  Corporation  or  another  established  clearing
corporation performing similar functions.

              (b) This Additional Investment Right is exercisable, either in its
entirety  or,  from time to time,  for a  portion  of the  number of  Additional
Investment  Right Shares.  Upon surrender of this  Additional  Investment  Right
following one or more partial exercises,  the Company shall issue or cause to be
issued, at its expense,  a New Additional  Investment Right evidencing the right
to purchase the remaining number of Additional Investment Right Shares.

              (c) In addition to any other rights available to a Holder,  if the
Company  fails to deliver to the Holder a  certificate  representing  Additional
Investment  Right Shares on the date on which  delivery of such  certificate  is
required by this Additional Investment Right, such Holder may notify the Company
via  facsimile,  mail  or  any  other  means,  of its  failure  to  deliver  the
certificate (a "Delivery  Failure  Notice").  If the Company fails to deliver to
the Holder a certificate  representing Additional Investment Right Shares by the
third Trading Day after  delivery of the Delivery  Failure  Notice by the Holder
and if after such third  Trading Day after the delivery of the Delivery  Failure
Notice the Holder purchases (in an open market  transaction or otherwise) shares
of  Common  Stock to  deliver  in  satisfaction  of a sale by the  Holder of the
Additional  Investment Right Shares that the Holder  anticipated  receiving from
the Company (a  "Buy-In"),  then the Company  shall,  within three  Trading Days
after the Holder's request and in the Holder's  discretion,  either (i) pay cash
to the Holder in an amount equal to the Holder's total purchase price (including
brokerage commissions,  if any) for the shares of Common Stock so purchased (the
"Buy-In  Price"),  at which  point the  Company's  obligation  to  deliver  such
certificate (and to issue such Common Stock) shall  terminate,  or (ii) promptly
honor its  obligation  to deliver to the Holder a  certificate  or  certificates
representing  such Common Stock and pay cash to the Holder in an amount equal to
the excess (if any) of the Buy-In  Price over the  product of (A) such number of
shares of Common  Stock,  times (B) the  Closing  Price on the date of the event
giving rise to the Company's obligation to deliver such certificate.

              (d) The  Company's  obligations  to issue and  deliver  Additional
Investment  Right  Shares in  accordance  with the terms hereof are absolute and
unconditional,  irrespective  of any action or inaction by the Holder to enforce
the same,  any  waiver or consent  with  respect to any  provision  hereof,  the
recovery of any  judgment  against any Person or any action to enforce the same,
or any setoff,  counterclaim,  recoupment,  limitation  or  termination,  or any
breach or alleged  breach by the Holder or any other Person of any obligation to
the Company or any  violation  or alleged  violation of law by the Holder or any
other Person,  and irrespective of any other  circumstance which might otherwise
limit  such  obligation  of the  Company to the  Holder in  connection  with the
issuance of Additional  Investment  Right Shares.  Nothing  herein shall limit a
Holder's right to pursue any other remedies available to it hereunder, at law or
in equity including, without limitation, a decree of specific performance and/or
injunctive  relief  with  respect to the  Company's  failure  to timely  deliver
certificates representing shares of Common Stock upon exercise of the Additional
Investment Right as required pursuant to the terms hereof.


                                       3


         6. Charges,  Taxes and Expenses.  Issuance and delivery of certificates
for shares of Common Stock upon  exercise of this  Additional  Investment  Right
shall be made  without  charge  to the  Holder  for any issue or  transfer  tax,
withholding  tax,  transfer  agent fee or other  incidental  tax or  expense  in
respect of the  issuance of such  certificates,  all of which taxes and expenses
shall be paid by the Company;  provided,  however, that the Company shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the registration of any  certificates for Additional  Investment Right Shares
or  Additional  Investment  Rights in a name other than that of the Holder or an
Affiliate  thereof.  The Holder shall be responsible for all other tax liability
that may arise as a result of holding or transferring this Additional Investment
Right or receiving Additional Investment Right Shares upon exercise hereof.

         7.  Replacement  of Additional  Investment  Right.  If this  Additional
Investment  Right is mutilated,  lost,  stolen or  destroyed,  the Company shall
issue  or  cause  to be  issued  in  exchange  and  substitution  for  and  upon
cancellation  hereof,  or in  lieu  of  and  substitution  for  this  Additional
Investment  Right, a New Additional  Investment  Right, but only upon receipt of
evidence  reasonably  satisfactory  to  the  Company  of  such  loss,  theft  or
destruction and customary and reasonable indemnity, if requested. Applicants for
a New Additional  Investment  Right under such  circumstances  shall also comply
with  such  other  reasonable  regulations  and  procedures  and pay such  other
reasonable third-party costs as the Company may prescribe.

         8.  Reservation  of Additional  Investment  Right  Shares.  The Company
covenants  that it will at all  times  reserve  and  keep  available  out of the
aggregate of its authorized but unissued and otherwise  unreserved Common Stock,
solely for the  purpose of  enabling  it to issue  Additional  Investment  Right
Shares upon exercise of this Additional Investment Right as herein provided, the
number  of  Additional  Investment  Right  Shares  which are then  issuable  and
deliverable upon the exercise of this entire  Additional  Investment Right, free
from preemptive rights or any other contingent  purchase rights of persons other
than the Holder (taking into account the adjustments and restrictions of Section
9).  The  Company  covenants  that all  Additional  Investment  Right  Shares so
issuable and deliverable  shall, upon issuance and the payment of the applicable
Exercise  Price  in  accordance  with the  terms  hereof,  be duly  and  validly
authorized,  issued and fully paid and nonassessable.  The Company will take all
such action as may be  necessary  to assure that such shares of Common Stock may
be  issued  as  provided  herein  without  violation  of any  applicable  law or
regulation,  or of any  requirements  of any  securities  exchange or  automated
quotation system upon which the Common Stock may be listed.

         9. Certain  Adjustments.  The Exercise  Price and number of  Additional
Investment  Right Shares  issuable upon exercise of this  Additional  Investment
Right are subject to  adjustment  from time to time as set forth in this Section
9.

              (a) Stock Dividends and Splits. If the Company,  at any time while
this Additional  Investment  Right is outstanding,  (i) pays a stock dividend on
its Common Stock or otherwise makes a distribution on any class of capital stock
that is payable in shares of Common Stock, (ii) subdivides outstanding shares of
Common  Stock into a larger  number of  shares,  or (iii)  combines  outstanding

                                       4


shares of Common Stock into a smaller  number of shares,  then in each such case
the  Exercise  Price shall be  multiplied  by a fraction of which the  numerator
shall be the number of shares of Common  Stock  outstanding  immediately  before
such event and of which the denominator  shall be the number of shares of Common
Stock outstanding  immediately after such event. Any adjustment made pursuant to
clause (i) of this paragraph shall become effective immediately after the record
date for the determination of stockholders  entitled to receive such dividend or
distribution,  and any  adjustment  pursuant  to  clauses  (ii) or (iii) of this
paragraph shall become  effective  immediately  after the effective date of such
subdivision or combination.

              (b) Pro Rata Distributions. If the Company, at any time while this
Additional  Investment  Right is  outstanding,  distributes to holders of Common
Stock  (i)  evidences  of its  indebtedness,  (ii) any  security  (other  than a
distribution of Common Stock covered by the preceding  paragraph),  (iii) rights
or warrants to subscribe for or purchase any  security,  or (iv) any other asset
(in each  case,  "Distributed  Property"),  then in each such case the  Exercise
Price in effect  immediately prior to the record date fixed for determination of
stockholders  entitled to receive such distribution shall be adjusted (effective
on such  record  date) to equal  the  product  of such  Exercise  Price  times a
fraction of which the denominator shall be the average of the Closing Prices for
the five Trading Days immediately  prior to (but not including) such record date
and of which the numerator shall be such average less the then fair market value
of the Distributed  Property  distributed in respect of one outstanding share of
Common  Stock,  as  determined by the  Company's  independent  certified  public
accountants that regularly  examine the financial  statements of the Company (an
"Appraiser").  In such event, the Holder,  after receipt of the determination by
the  Appraiser,  shall have the right to select an additional  appraiser  (which
shall be a  nationally  recognized  accounting  firm),  in which  case such fair
market  value shall be deemed to equal the average of the values  determined  by
each of the Appraiser and such  appraiser.  As an  alternative  to the foregoing
adjustment  to the Exercise  Price,  at the  Company's  option,  the Company may
deliver to such Holder,  the  Distributed  Property  that such Holder would have
been entitled to receive in respect of the  Additional  Investment  Right Shares
for which this Additional Investment Right could have been exercised immediately
prior to such record date.  If such  Distributed  Property is not delivered to a
Holder  pursuant  to the  preceding  sentence,  then upon  expiration  of or any
exercise of the Additional  Investment Right that occurs after such record date,
such Holder  shall  remain  entitled to receive,  in addition to the  Additional
Investment Right Shares  otherwise  issuable upon such exercise (if applicable),
such Distributed Property.

              (c)  Fundamental   Transactions.   If,  at  any  time  while  this
Additional  Investment Right is outstanding,  (i) the Company effects any merger
or  consolidation  of the Company with or into another Person,  (ii) the Company
effects any sale of all or substantially all of its assets in one or a series of
related  transactions,  (iii) any tender offer or exchange offer (whether by the
Company or another  Person) is  completed  pursuant  to which  holders of Common
Stock are  permitted to tender or exchange  their  shares for other  securities,
cash or property, or (iv) the Company effects any reclassification of the Common

                                       5


Stock or any  compulsory  share  exchange  pursuant to which the Common Stock is
effectively  converted into or exchanged for other securities,  cash or property
(other  than as a result of a  subdivision  or  combination  of shares of Common
Stock  covered  by  Section  9(a)  above)  (in any  such  case,  a  "Fundamental
Transaction"),  then the Holder shall have the right thereafter to receive, upon
exercise  of this  Additional  Investment  Right,  the same  amount  and kind of
securities,  cash or property as it would have been entitled to receive upon the
occurrence of such Fundamental  Transaction if it had been, immediately prior to
such Fundamental Transaction,  the holder of the number of Additional Investment
Right Shares then issuable upon exercise in full of this  Additional  Investment
Right (the  "Alternate  Consideration").  The aggregate  Exercise Price for this
Additional  Investment  Right  will  not be  affected  by any  such  Fundamental
Transaction, but the Company shall apportion such aggregate Exercise Price among
the Alternate Consideration in a reasonable manner reflecting the relative value
of any different  components of the  Alternate  Consideration.  The terms of any
agreement pursuant to which a Fundamental  Transaction is effected shall include
terms  requiring  any such  successor  or  surviving  entity to comply  with the
provisions of this  paragraph (c) and insuring  that the  Additional  Investment
Right (or any such  replacement  security)  will be similarly  adjusted upon any
subsequent   transaction  analogous  to  a  Fundamental   Transaction.   If  any
Fundamental  Transaction  constitutes  or  results  in a Change of  Control  (as
defined below),  then at the request of the Holder delivered before the 90th day
after such  Fundamental  Transaction,  the  Company  (or any such  successor  or
surviving entity) will purchase the Additional  Investment Right from the Holder
for a  purchase  price,  payable in cash  within  five  Trading  Days after such
request (or, if later,  on the effective date of the  Fundamental  Transaction),
equal to the Black Scholes value of the  remaining  unexercised  portion of this
Additional  Investment  Right on the  date of such  request  (assuming  that the
length  of this  Additional  Investment  Right  is 180 days  following  the date
hereof).  For the purposes of this Section 9(c),  "Change of Control"  means (i)
consummation  of a "Rule 13e-3  transaction"  as defined in Rule 13e-3 under the
Exchange Act with respect to the Company,  or (ii) the  execution by the Company
or its  controlling  shareholders  of an agreement  providing  for or reasonably
likely to result in any of the foregoing events.

              (d) Number of Additional  Investment Right Shares.  Simultaneously
with any  adjustment to the Exercise  Price pursuant to paragraphs (a) or (b) of
this  Section,  the number of  Additional  Investment  Right  Shares that may be
purchased upon exercise of this Additional  Investment  Right shall be increased
or  decreased  proportionately,  so that after  such  adjustment  the  aggregate
Exercise  Price  payable  hereunder  for the  increased or  decreased  number of
Additional  Investment Right Shares shall be the same as the aggregate  Exercise
Price in effect immediately prior to such adjustment.

              (e) Calculations.  All calculations  under this Section 9 shall be
made to the nearest cent or the nearest 1/100th of a share,  as applicable.  The
number of shares of Common Stock outstanding at any given time shall not include
shares owned or held by or for the account of the Company,  and the  disposition
of any such shares shall be considered an issue or sale of Common Stock.

              (f) Notice of Adjustments.  Upon the occurrence of each adjustment
pursuant to this  Section 9, the Company at its expense  will  promptly  compute
such adjustment in accordance with the terms of this Additional Investment Right
and prepare a certificate  setting forth such adjustment,  including a statement
of the  adjusted  Exercise  Price  and  adjusted  number  or type of  Additional
Investment  Right  Shares or other  securities  issuable  upon  exercise of this
Additional Investment Right (as applicable),  describing the transactions giving
rise to such  adjustments  and  showing  in detail  the facts  upon  which  such
adjustment is based.  Upon written request,  the Company will promptly deliver a
copy of each such certificate to the Holder and to the Company's Transfer Agent.


                                       6


              (g) Notice of  Corporate  Events.  If the Company  (i)  declares a
dividend or any other  distribution  of cash,  securities  or other  property in
respect of its Common  Stock,  including,  without  limitation,  any granting of
rights or warrants to subscribe for or purchase any capital stock of the Company
or any  Subsidiary,  (ii)  authorizes  or  approves,  enters into any  agreement
contemplating or solicits stockholder  approval for any Fundamental  Transaction
or (iii) authorizes the voluntary dissolution,  liquidation or winding up of the
affairs of the Company,  then the Company  shall  deliver to the Holder a notice
describing the material terms and  conditions of such  transaction,  at least 20
calendar days prior to the applicable record or effective date on which a Person
would need to hold Common Stock in order to  participate in or vote with respect
to such transaction, and the Company will take all steps reasonably necessary in
order to insure that the Holder is given the practical  opportunity  to exercise
this Additional  Investment  Right prior to such time so as to participate in or
vote with respect to such transaction;  provided,  however,  that the failure to
deliver such notice or any defect  therein  shall not affect the validity of the
corporate action required to be described in such notice.

         10. Payment of Exercise Price.  The Holder shall pay the Exercise Price
in immediately available funds; provided, however, if the Registration Statement
did not become  effective on or before  Required  Effectiveness  Date and is not
continuously  effective  through the Expiration Date, the Holder may satisfy its
obligation  to pay the Exercise  Price  through a "cashless  exercise," in which
event the Company shall issue to the Holder the number of Additional  Investment
Right Shares determined as follows:

                               X = Y [(A-B)/A]
                  where:
                               X = the number of Additional  Investment
                                   Right Shares to be issued to the Holder.

                               Y = the   number   of   Additional Investment
                                   Right Shares with respect to which this
                                   Additional Investment Right is being
                                   exercised.

                               A = the average of the Closing Prices
                                   for the five Trading Days immediately
                                   prior  to  (but  not  including)  the
                                   Exercise Date.

                               B = the Exercise Price.

              For purposes of Rule 144 promulgated  under the Securities Act, it
is intended,  understood and acknowledged  that the Additional  Investment Right
Shares issued in a cashless  exercise  transaction  shall be deemed to have been
acquired by the Holder,  and the holding  period for the  Additional  Investment
Right  Shares  shall be deemed to have  commenced,  on the date this  Additional
Investment Right was originally issued pursuant to the Purchase Agreement.

         11.  Limitation on Exercise.  Notwithstanding  anything to the contrary
contained  herein,  the number of shares of Common Stock that may be acquired by
the Holder upon any exercise of this Additional  Investment  Right (or otherwise
in respect  hereof)  shall be limited to the extent  necessary  to insure  that,
following  such  exercise  (or other  issuance),  the total  number of shares of

                                       7


Common Stock then  beneficially  owned by such Holder and its Affiliates and any
other  Persons  whose  beneficial  ownership of Common Stock would be aggregated
with the Holder's for purposes of Section  13(d) of the Exchange  Act,  does not
exceed  4.999%  (the  "Maximum  Percentage")  of the total  number of issued and
outstanding  shares of Common  Stock  (including  for such purpose the shares of
Common  Stock  issuable  upon  such  exercise).  For such  purposes,  beneficial
ownership  shall be determined in accordance  with Section 13(d) of the Exchange
Act and the rules and regulations  promulgated  thereunder.  Each delivery of an
Exercise Notice hereunder will constitute a representation by the Holder that it
has evaluated the limitation  set forth in this  paragraph and  determined  that
issuance of the full number of Additional  Investment  Right Shares requested in
such Exercise Notice is permitted under this paragraph. Notwithstanding anything
herein to the contrary, the Company's obligation to issue shares of Common Stock
in excess of the limitation  referred to in this Section shall be suspended (and
shall not terminate or expire  notwithstanding  any contrary  provisions hereof)
until  such  time,  if any,  as such  shares  of  Common  Stock may be issued in
compliance with such  limitation.  By written notice to the Company,  the Holder
may waive the  provisions  of this  Section or increase or decrease  the Maximum
Percentage to any other  percentage  specified in such notice,  but (i) any such
waiver or increase will not be effective until the 61st day after such notice is
delivered to the Company,  and (ii) any such waiver or increase or decrease will
apply only to the Holder and not to any other  holder of  Additional  Investment
Rights.

         12.  Fractional  Shares.  The Company shall not be required to issue or
cause to be issued fractional Additional Investment Right Shares on the exercise
of this Additional  Investment Right. If any fraction of a Additional Investment
Right Share would,  except for the provisions of this Section,  be issuable upon
exercise  of  this  Additional   Investment  Right,  the  number  of  Additional
Investment  Right  Shares to be issued will be rounded up to the  nearest  whole
share.

         13. Notices.  Any and all notices or other communications or deliveries
hereunder (including without limitation any Exercise Notice) shall be in writing
and  shall be deemed  given and  effective  on the  earliest  of (i) the date of
transmission,  if such  notice  or  communication  is  delivered  via  confirmed
facsimile at the facsimile  number  specified in this Section prior to 5:30 p.m.
(New York City time) on a Trading Day,  (ii) the next Trading Day after the date
of  transmission,  if such notice or  communication  is delivered  via confirmed
facsimile at the facsimile number specified in this Section on a day that is not
