            NovaDel Pharma Inc.
Attention:  Board of Directors

            RE:   NOVADEL PHARMA INC. 1998 STOCK OPTION PLAN
                  PURCHASE OF OPTION SHARES

Gentlemen:

      In  accordance  with  the  Stock  Option  Agreement  dated  [INSERT  DATE]
("Agreement")  between [INSERT NAME]  ("Optionee")  and NovaDel Pharma Inc. (the
"Company"),  the  Optionee  hereby  irrevocably  elects to exercise the right to
purchase  [INSERT NUMBER] shares of the Company's  common stock, par value $.001
per share ("Common Stock"), which are being purchased for investment and not for
resale.  All  capitalized  terms not  defined  herein  shall  have the  meanings
ascribed to them in the Plan.

      As payment  for my shares,  enclosed  is (check  and  complete  applicable
box[es]):

      ------
                   a [company  check]  [certified  check] [bank check] payable
                   to the  order  of  "NovaDel  Pharma  Inc."  in  the  sum of
                   $__________;
      ------

      ------
                   confirmation   of   wire   transfer   in  the   amount   of
                   $__________; and/or

      ------

      The Optionee hereby represents,  warrants to, and agrees with, the Company
that

            (i) The Optionee is acquiring  the Option Shares for its own account
for  investment  purposes  only  and not with a view to,  or for the  resale  in
connection with any "distribution" thereof for purposes of the Securities Act of
1933 (the "1933 Act");

            (ii) The  Optionee is aware of the  Company's  business  affairs and
financial condition,  and have acquired sufficient information about the Company
to reach an informed and knowledgeable  decision to acquire the securities.  The
Optionee has received a copy of all reports and  documents  required to be filed
by the Company with the Commission  pursuant to the Securities Exchange Act 1934
("Exchange Act") within the last 24 months and all reports issued by the Company
to its stockholders;

                                       1
<PAGE>

            (iii) The Optionee  understands  that it must bear for an indefinite
period of time the economic risk of an investment  in the Option  Shares,  which
cannot  be sold by me  unless  they  are  registered  under  the  1933 Act or an
exemption  therefrom  is available  thereunder  and that the Company is under no
obligation to register the Option Shares for sale under the 1933 Act;

            (iv) In its position with the Company, the Optionee has had both the
opportunity to ask questions and receive answers from the officers and directors
of the  Company and all persons  acting on its behalf  concerning  the terms and
conditions of the offer made hereunder and to obtain any additional  information
to the extent the Company possess or may possess such information or can acquire
it without  unreasonable  effort or expense  necessary to verify the accuracy of
the information obtained pursuant to clause (ii) above;

            (v) The Optionee is aware that the Company shall place stop transfer
orders with its transfer  agent against the transfer of the Option Shares in the
absence of registration under the 1933 Act or an exemption therefrom as provided
herein;

            (vi) The Optionee's  rights with respect to the Option Shares shall,
in all respects,  be subject to the terms and  conditions of this Company's 1998
Stock Option Plan and this Agreement; and

            (vii) the  certificates  evidencing the Option Shares shall bear the
following legends:

            "The shares  represented by this  certificate have been acquired for
            investment and have not been registered  under the Securities Act of
            1933.  The shares may not be sold or  transferred  in the absence of
            such registration or an exemption therefrom under said Act."

            "The  shares  represented  by this  certificate  have been  acquired
            pursuant to a Stock Option Agreement, dated [INSERT DATE], a copy of
            which  is on file  with  the  Company,  and may not be  transferred,
            pledged  or  disposed  of  except in  accordance  with the terms and
            conditions thereof."

            (viii) The  Optionee is familiar  with the  provisions  of Rule 144,
promulgated  under the 1933 Act,  which,  in substance,  permits  limited public
resale of "restricted  securities"  acquired,  directly or indirectly,  from the
issuer thereof (or from an affiliate of such issuer),  in a non-public  offering
subject  to the  satisfaction  of certain  conditions,  including,  among  other
things:  (1) the availability of certain public  information  about the Company;
(2) the resale  occurring not less than one year after the party has  purchased,
and made full payment  within the meaning of Rule 144, for the  securities to be
sold; and, in the case of an affiliate,  or of a non-affiliate  who has held the
securities  less than two years,  (2) the sale being made through a broker in an
unsolicited  "broker's  transaction" or in  transactions  directly with a market
maker  (as said  term is  defined  under  the  Exchange  Act) and the  amount of
securities being sold during any three-month  period not exceeding the specified
limitations stated in Rule 144, if applicable.

                                       2
<PAGE>

            (ix) The Optionee further understands that at the time it decides to
sell the  securities  there may be no public  market  upon  which to make such a
sale, and that, even if such a public market then exists, the Company may not be
satisfying the current public information requirements of Rule 144, and that, in
such event,  the Optionee would be precluded  from selling the securities  under
Rule 144 even if the one-year minimum holding period is satisfied.

            (x) The Optionee  further  understands  that in the event all of the
applicable  requirements of Rule 144 are not satisfied,  registration  under the
1933 Act,  or some other  registration  exemption  will be  required;  and that,
notwithstanding  the fact that Rule 144 is not  exclusive,  the Staff of the SEC
has  expressed  its opinion  that persons  proposing  to sell private  placement
securities  other than in a registered  offering and otherwise  than pursuant to
Rule 144 will  have a  substantial  burden  of  proof  in  establishing  that an
exemption from registration is available for such offers or sales, and that such
persons and their respective  brokers who participate in such transactions do so
at their own risk.

Kindly forward to me my certificate at your earliest convenience.

Very truly yours,

officers  and  directors  of the Company  and all  persons  acting on its behalf
concerning  the terms and  conditions of the offer made  hereunder and to obtain
any additional  information  to the extent the Company  possesses or may possess
such  information  or can  acquire  it  without  unreasonable  effort or expense
necessary to verify the accuracy of the  information  contained in the Company's
offering documents.

      6.4 TRANSFER  RESTRICTIONS.  The Optionee is aware that the Company  shall
place stop transfer  orders with its transfer  agent against the transfer of the
Option Shares in the absence of registration  under the 1933 Act or an exemption
therefrom as provided herein; and

      6.5 LEGENDS. The certificates  evidencing the Option Shares shall bear the
following legends:

            "The shares  represented by this  certificate have been acquired for
            investment and have not been registered  under the Securities Act of
            1933.  The shares may not be sold or  transferred  in the absence of
            such registration or an exemption therefrom under the 1933 Act."

            "The  shares  represented  by this  certificate  have been  acquired
            pursuant to a Stock Option  Agreement,  dated as of [INSERT DATE], a
            copy  of  which  is on  file  with  the  Company,  and  may  not  be
            transferred,  pledged or disposed of except in  accordance  with the
            terms and

            conditions thereof."

7.  WITHHOLDING TAX. Not later than the date as of which an amount first becomes
includable  in the gross income of the Optionee for Federal  income tax purposes
with  respect to the Option,  the  Optionee  shall pay to the  Company,  or make
arrangements  satisfactory  to the  Committee  regarding  the  payment  of,  any
Federal,  state and local  taxes of any kind  required  by law to be withheld or
paid with respect to such amount.  The  obligations  of the Company  pursuant to
this Agreement shall be conditional  upon such payment or arrangements  with the
Company and the Company shall, to the extent permitted by law, have the right to
deduct any such taxes from any payment of any kind otherwise due to the Optionee
from the Company.

8.  TERMINATION OF [DESCRIBE].  If the Optionee ceases to serve as [DESCRIBE] of
the Company,  Optionee  may, but only for a period of thirty (30) days after the
date on which Optionee  ceased to be a [DESCRIBE] of the Company,  exercise this
Option,  to the extent  Optionee  was  entitled  to  exercise  it at the date of
termination. If, however, Optionee's [DESCRIBE] is terminated by the Company for
Cause, as commonly defined, this Option shall become void effective upon the act
of termination.

9. DEATH OR  INCAPACITY  OF  OPTIONEE.  This Option  shall  survive the death or
incapacity  of the  Optionee,  and shall  bind and enure to the  benefit  of the
Optionee's heirs, executors, administrators of personal representatives.

contrary  notwithstanding,  the Optionee  hereby  agrees that it shall not sell,
transfer by any means or otherwise  dispose of the Option Shares  acquired by it
without  registration  under the 1933 Act,  or in the event that they are not so
registered,  unless (i) an exemption from the 1933 Act registration requirements
is available  thereunder,  and (ii) the Optionee has  furnished the Company with
notice  of such  proposed  transfer  and the  Company's  legal  counsel,  in its
reasonable opinion, shall deem such proposed transfer to be so exempt.

NovaDel Pharma Inc.

Attention:  Board of Directors

            RE:   NOVADEL PHARMA INC.
                  PURCHASE OF OPTION SHARES

Gentlemen:

      In accordance  with the Stock Option  Agreement  dated as of [INSERT DATE]
("Agreement")  between [INSERT NAME]  ("Optionee")  and Novadel Pharma Inc. (the
"Company"),  the  Optionee  hereby  irrevocably  elects to exercise the right to
purchase  ___________  shares of the Company's common stock, par value $.001 per
share  ("Common  Stock"),  which are being  purchased for investment and not for
resale.

      As payment  for my shares,  enclosed  is (check  and  complete  applicable
box[es]):

      ------
                   a [certified  check]  [bank check]  payable to the order of
                   "NovaDel Pharma Inc." in the sum of $__________;
      ------

      ------
                   confirmation   of   wire   transfer   in  the   amount   of
                   $__________; and/or
      ------

      ------
                   cashless exercise per paragraph 5.3.4

      ------

      The Optionee hereby represents,  warrants to, and agrees with, the Company
that

            (i) The Optionee is acquiring  the Option Shares for his own account
for  investment  purposes  only  and not with a view to,  or for the  resale  in
connection with any "distribution" thereof for purposes of the Securities Act of
1933 (the "1933 Act");

            (ii) The  Optionee is aware of the  Company's  business  affairs and
financial condition,  and have acquired sufficient information about the Company
to reach an informed and knowledgeable  decision to acquire the securities.  The
Optionee has received a copy of all reports and  documents  required to be filed
by the Company with the Commission  pursuant to the  Securities  Exchange Act of
1934  ("Exchange  Act") within the last 24 months and all reports  issued by the
Company to its stockholders;

                                       6
<PAGE>

            (iii) The Optionee  understands  that he must bear for an indefinite
period of time the economic risk of an investment  in the Option  Shares,  which
cannot  be sold by him  unless  they  are  registered  under  the 1933 Act or an
exemption  therefrom  is available  thereunder  and that the Company is under no
obligation to register the Option Shares for sale under the 1933 Act;

            (iv) In his position with the Company, the Optionee has had both the
opportunity to ask questions and receive answers from the officers and directors
of the  Company and all persons  acting on its behalf  concerning  the terms and
conditions of the offer made hereunder and to obtain any additional  information
to the extent the Company possess or may possess such information or can acquire
it without  unreasonable  effort or expense  necessary to verify the accuracy of
the information obtained pursuant to clause (ii) above;

            (v) The Optionee is aware that the Company shall place stop transfer
orders with its transfer  agent against the transfer of the Option Shares in the
absence of registration under the 1933 Act or an exemption therefrom as provided
herein;

            (vi) The Optionee's  rights with respect to the Option Shares shall,
in all respects, be subject to the terms and conditions of this Agreement; and

            (vii) the  certificates  evidencing the Option Shares shall bear the
following legends:

            "The shares  represented by this  certificate have been acquired for
            investment and have not been registered  under the Securities Act of
            1933.  The shares may not be sold or  transferred  in the absence of
            such registration or an exemption therefrom under said Act."

            "The  shares  represented  by this  certificate  have been  acquired
            pursuant to a Stock Option  Agreement,  dated as of [INSERT DATE], a
            copy  of  which  is on  file  with  the  Company,  and  may  not  be
            transferred,  pledged or disposed of except in  accordance  with the
            terms and conditions thereof."

            (viii) The  Optionee is familiar  with the  provisions  of Rule 144,
promulgated  under the 1933 Act,  which,  in substance,  permits  limited public
resale of "restricted  securities"  acquired,  directly or indirectly,  from the
issuer thereof (or from an affiliate of such issuer),  in a non-public  offering
subject  to the  satisfaction  of certain  conditions,  including,  among  other
things:  (1) the availability of certain public  information  about the Company;
(2) the resale  occurring not less than one year after the party has  purchased,
and made full payment  within the meaning of Rule 144, for the  securities to be

                                       7
<PAGE>

sold; and, in the case of an affiliate,  or of a non-affiliate  who has held the
securities  less than two years,  (3) the sale being made through a broker in an
unsolicited  "broker's  transaction" or in  transactions  directly with a market
maker (as said term is defined under  Exchange Act) and the amount of securities
being sold during any three-month period not exceeding the specified limitations
stated in Rule 144, if applicable.

            (ix) The Optionee further understands that at the time he decides to
sell the  securities  there may be no public  market  upon  which to make such a
sale, and that, even if such a public market then exists, the Company may not be
satisfying the current public information requirements of Rule 144, and that, in
such event,  the Optionee would be precluded  from selling the securities  under
Rule 144 even if the one-year minimum holding period is satisfied.

            (x) The Optionee  further  understands  that in the event all of the
applicable  requirements of Rule 144 are not satisfied,  registration  under the
1933 Act,  or some other  registration  exemption  will be  required;  and that,
notwithstanding  the fact that Rule 144 is not  exclusive,  the Staff of the SEC
has  expressed  its opinion  that persons  proposing  to sell private  placement
securities  other than in a registered  offering and otherwise  than pursuant to
Rule 144 will  have a  substantial  burden  of  proof  in  establishing  that an
exemption from registration is available for such offers or sales, and that such
persons and their respective  brokers who participate in such transactions do so
at their own risk.

Kindly forward to me my certificate at your earliest convenience.

Very truly yours,
