                              DEVELOPMENT AGREEMENT

         THIS AGREEMENT is made by and between Kos Pharmaceuticals, Inc., a
corporation of the State of Florida, with a place of business at 1001 South
Bayshore Drive, Suite 2502, Miami, FL 33131 (hereinafter referred to as "Kos")
and Fuisz Technologies Ltd., a corporation of the State of Delaware with a place
of business at 3810 Concorde Parkway, Suite 100, Chantilly, VA 22021
(hereinafter referred to as "Fuisz").

         WHEREAS, Fuisz has over a period of years conducted research and
development work and developed proprietary technology which is useful to make
controlled-release formulations for pharmaceutical compounds; and

         WHEREAS Kos has interests in developing, manufacturing and marketing
once-a-day oral solid dosage forms of Captopril (as hereinafter defined), based
on Fuisz proprietary technology; and

         WHEREAS, Fuisz and Kos are each willing to undertake a Development
Program (as hereinafter defined) for development of the foregoing products for
commercial marketing and sale.

            Now, therefore, the parties agree as follows:

            The definitions as used herein are set forth in Article 1 of the
License Agreement and Appendix A attached hereto and incorporated herein by
reference.

ARTICLE 1 - DEVELOPMENT PROGRAM

1.1         Fuisz and Kos shall jointly undertake using reasonable best

purposes of developing and producing Products and shall be carried out generally
in accordance with Appendix B.

1.2         Each party shall appoint a Program Manager for overall management of
the Development Program and such Program Managers shall by mutual agreement
provide the direction of the program and the scope of work to be undertaken 
under the Development Program; provided, however, that Kos shall determine the 
focus of work which the Program Managers mutually agree can be carried out 
under the


<PAGE>

Development Program, within the guidelines set forth in Appendix B. The initial
Program Manager for Kos shall be designated within thirty (30) days and the
initial Program Manager for Fuisz shall be ***************. Each party may
change the designated Program Manager upon written notice to the other party of
such change.

1.3         During the term of the Development Program Fuisz shall periodically
provide to Kos samples of materials for evaluation by Kos. Kos shall promptly
evaluate such samples and provide guidance to Fuisz for further work based on
the results of such evaluations. During the Development Program term, Program
Managers or representatives of the parties shall meet from time to time to
discuss planning and progress of the Development Program to carry out efficient
and effective activities. Fuisz shall provide project updates to Kos verbally
and/or in written form ******************** during the Development Program, and
shall provide a written report upon completion of the Development Program. All
such discussions and activities shall be considered as carried out under the
Development Program.

1.4         Kos shall supply to Fuisz, at Kos's cost and expense, materials
including Captopril which Kos believes are essential for carrying out the
Development Program. All such materials supplied by Kos shall be materials
approved for human uses unless otherwise specifically designated and Kos shall
supply MSDS sheets where necessary for the processing of such materials. Fuisz
shall advise Kos from time to time of its requirements for such materials for
the Development Program.

1.5         Upon termination of each Phase of the Development Program, Fuisz
shall provide to Kos quantities of prototype Products processed using Technology
which demonstrate the best results obtained under the Development Program. Kos
shall provide to Fuisz all data, information and conclusions generated during
the Development Program relating to the Development Program and/or Technology
including without limitation ******************** and any other mutually agreed
pre-defined data, and Fuisz shall have the ****************** to use all such
data, information and conclusions; provided, however, that Fuisz shall not
utilize such data, information and conclusions to the detriment of the
competitive position of Kos or inappropriately identify Kos in any publicity
concerning same.

1.6         In the event special processing or manufacturing equipment
specifically modified or adapted for use with Technology is requested by Kos to
be used under the Development Program, Kos shall provide such equipment to Fuisz
for the duration of the Development Program.

1.7         All activities in connection with the Development Program shall be
carried out by each party in strict compliance with any applicable federal,
state or local laws, regulations or guidelines governing such activities.

the prior request and approval of Kos in connection with meetings, activities or
reviews of activities under the Development Program.

1.9         All equipment, supplies and other items purchased by either party
for the conduct of the Development Program, shall be the sole and exclusive
property of the purchasing party. For purposes hereof, all such items purchased
by Fuisz with funds provided by Kos shall be deemed to be items purchased and
owned by *****.

ARTICLE 2 - TERM AND TERMINATION OF THE DEVELOPMENT PROGRAM

2.1         The initial term of Phase I of the Development Program shall be
*********** weeks from the Effective Date. The parties shall use reasonable
efforts to carry out the Development Program during such initial term. However,
if due to unforseen circumstances unavoidable delays attributable solely to
Fuisz are encountered, or force majeure events are encountered in carrying out
activities, the initial term of the Development Program shall be extended for a
time equal to the delay at no additional cost to Kos. The Development Program
shall be automatically extended on a week by week basis after the initial term
provided that Kos may terminate the Development Program anytime after the
initial term or at the end of each successive weekly extension of the
Development Program, and Fuisz may terminate the Development Program at the end
of the *********** weekly extension thereof or at the end of each successive
weekly extension thereafter, respectively upon ********* calendar days advance
notice in writing to the other party.

2.2         If either party shall default, fail to perform, or otherwise commit
a breach of a material obligation or any covenant contained herein with respect
to the Development Program, and shall fail to remedy such default, failure to
perform or breach within ********** days after its receipt of written notice
thereof from the other party, such other party may terminate the Development
Program and incur no further obligation hereunder, it being understood, however,
that if within such ********** days after receipt of such notice, the party in
default shall have rectified its default, then the Development Program and the
terms hereof relating to the Development Program shall be restored as if no
termination of the Development Program had occurred. The term of this Agreement
(or any extension thereof) shall be tolled by the time required by the
defaulting party to cure the default.

                                        3

<PAGE>

2.3         This Agreement shall commence upon the Effective Date and terminate
at the end of the term of the Development Program, including any extensions
thereof.

2.4         Except for Kos and Fuisz jointly owned technology and patents and
Fuisz solely owned technology and patents, Fuisz hereby acknowledges that it
shall not have the right, following expiration of the Development Agreement
term, to use technology to the extent obtained from Kos, patents based thereon
or any materials to the extent obtained from Kos, for any purpose without
obtaining a license from Kos, which license Kos, in its sole discretion, may
grant or deny.

2.5         Except as set forth in the License Agreement and except for Kos and
Fuisz jointly owned technology and patents and Kos solely owned technology and
patents, Kos hereby acknowledges that it shall not have the right, following
expiration of the Development Agreement term, to use Technology to the extent
obtained from Fuisz, patents based thereon or any materials to the extent
obtained from Fuisz, for any purpose without obtaining a license from Fuisz,
which license Fuisz, in its sole discretion, may grant or deny.

ARTICLE 3 - FUNDING OF THE DEVELOPMENT PROGRAM

3.1         Kos shall provide total funding for the Development Program as set
forth in Appendix B, in the amount of **************************************8
*****************************************************************************
************************* of which shall be paid to Fuisz within ********* days
of the Effective Date, and ******************************** of which shall be
paid within *********** days following the end of Phase 1 and
******************************** of which shall be paid within ********* days
following completion of the ********************* of Appendix B. This amount of
funding may be increased by mutual agreement. This funding shall not include the
cost of the ********************* which shall be funded and paid for
*************. In the event Kos chooses to proceed to Phase 2 and/or Phase 3 as
set forth in Appendix B, unless Fuisz determines further development is not
feasible, Kos shall pay to Fuisz additional amounts commensurate with the
activity involved and as mutually agreed, consistent with the cost of Phase 1
and with the level of activity, for Phase 2 and for Phase 3, payable within
*********** days of commencement of the phases.

3.2         In the event the Development Program is extended by mutual written
agreement of the parties, each successive one (1) week extension after the
initial term shall be funded and paid to Fuisz in advance at a rate of
********************************** per week with respect to extension of Phase
I, and with respect to Phases 2 and 3, such weekly amounts as are consistent
with the additional funding set forth in Section 3.1; provided, however, that if
the man-day charges for work carried out at Fuisz during the initial term are
less than the funding actually paid

                                        4

<PAGE>

under the initial term (exclusive of charges under Section 1.8) then additional
funding for such extensions under this Section 3.2 shall not be invoiced or due
until such time as the man-day charges equal such funding provided for the
initial term. Other costs as set forth in Section 1.8 associated with successive
weekly extensions incurred under the Development Program, shall be invoiced once
each month and will be due *************** days from date of mailing of the
invoice.

3.3         All work done at Fuisz shall be at *************** rates of Fuisz
for pharmaceutical development work. Verification of the man-days charges for
work under the Development Program and the schedule of applicable existing
charge rates shall be made available to Kos at reasonable intervals upon written
request. In the event Kos requests work be done in excess of the current funding
during the initial term of the Development Agreement or any extensions thereof,
Fuisz shall invoice Kos for such excess work on a monthly basis. In the event
either party terminates the Development Program, Kos shall be obligated to pay
Fuisz for all work done by Fuisz under the Development Program up to the date of
termination, and if terminated by Kos for breach by Fuisz, Fuisz shall refund
any advanced funding payments made by Kos in excess of payments for work done.

other party.

ARTICLE 5 - FORCE MAJEURE

                              DEVELOPMENT AGREEMENT

         THIS AGREEMENT is made by and between Kos Pharmaceuticals, Inc., a
corporation of the State of Florida, with a place of business at 1001 South
Bayshore Drive, Suite 2502, Miami, FL 33131 (hereinafter referred to as "Kos")
and Fuisz Technologies Ltd., a corporation of the State of Delaware with a place
of business at 3810 Concorde Parkway, Suite 100, Chantilly, VA 22021
(hereinafter referred to as "Fuisz").

         WHEREAS, Fuisz has over a period of years conducted research and
development work and developed proprietary technology which is useful to make
controlled-release formulations for pharmaceutical compounds; and

         WHEREAS Kos has interests in developing, manufacturing and marketing
once-a-day oral solid dosage forms of IS-5-MN (as hereinafter defined), based on
Fuisz proprietary technology; and

         WHEREAS, Fuisz and Kos are each willing to undertake a Development
Program (as hereinafter defined) for development of the foregoing products for
commercial marketing and sale.

         Now, therefore, the parties agree as follows:

         The definitions as used herein are set forth in Article 1 of the
License Agreement and Appendix A attached hereto and incorporated herein by
reference.

ARTICLE 1 - DEVELOPMENT PROGRAM

understood that this Development Program is primarily for the purposes of
developing and producing Products and shall be carried out generally in
accordance with Appendix B.

1.2         Each party shall appoint a Program Manager for overall management of
the Development Program and such Program Managers shall by mutual agreement
provide the direction of the program and the scope of work to be undertaken
under the Development Program; provided, however, that Kos shall determine the
focus of work which the Program Managers mutually agree can be carried out under
the


<PAGE>



Development Program, within the guidelines set forth in Appendix B. The initial
Program Manager for Kos shall be designated within thirty (30) days and the
initial Program Manager for Fuisz shall be ***************. Each party may
change the designated Program Manager upon written notice to the other party of
such change.

1.3         During the term of the Development Program Fuisz shall periodically
provide to Kos samples of materials for evaluation by Kos. Kos shall promptly
evaluate such samples and provide guidance to Fuisz for further work based on
the results of such evaluations. During the Development Program term, Program
Managers or representatives of the parties shall meet from time to time to
discuss planning and progress of the Development Program to carry out efficient
and effective activities. Fuisz shall provide project updates to Kos verbally
and/or in written form ******************** during the Development Program, and

Development Program.

1.4         Kos shall supply to Fuisz, at Kos's cost and expense, materials
including IS-5-MN which Kos believes are essential for carrying out the
Development Program. All such materials supplied by Kos shall be materials
approved for human uses unless otherwise specifically designated and Kos shall
supply MSDS sheets where necessary for the processing of such materials. Fuisz
shall advise Kos from time to time of its requirements for such materials for
the Development Program.

1.5         Upon termination of each Phase of the Development Program, Fuisz
shall provide to Kos quantities of prototype Products processed using Technology
which demonstrate the best results obtained under the Development Program. Kos
shall provide to Fuisz all data, information and conclusions generated during
the Development Program relating to the Development Program and/or Technology
including without limitation ******************** and any other mutually agreed
pre-defined data, and Fuisz shall have the ****************** to use all such
data, information and conclusions; provided, however, that Fuisz shall not
utilize such data, information and conclusions to the detriment of the
competitive position of Kos or inappropriately identify Kos in any publicity
concerning same.

1.6         In the event special processing or manufacturing equipment
specifically modified or adapted for use with Technology is requested by Kos to

1.7         All activities in connection with the Development Program shall be
carried out by each party in strict compliance with any applicable federal,
state or local laws, regulations or guidelines governing such activities.

<PAGE>

1.8         In addition to the funding under Article 3, Kos shall pay for the
cost of all materials including IS-5-MN used in the Development Program and
approved by Kos (to the extent such materials are not provided and fully paid by
Kos), and Kos shall pay for the costs of all shipping, packing, customs, duties
and customs clearances associated with shipment of materials and/or equipment to
or from Fuisz or for, or resulting from work under, the Development Program. In
addition, Kos shall pay for the reasonable costs of travel of Fuisz personnel at
the prior request and approval of Kos in connection with meetings, activities or
reviews of activities under the Development Program.

1.9         All equipment, supplies and other items purchased by either party
for the conduct of the Development Program, shall be the sole and exclusive
property of the purchasing party. For purposes hereof, all such items purchased
by Fuisz with funds provided by Kos shall be deemed to be items purchased and
owned by *****.

ARTICLE 2 - TERM AND TERMINATION OF THE DEVELOPMENT PROGRAM

2.1         The initial term of Phase I of the Development Program shall be
***************** from the Effective Date. The parties shall use reasonable
efforts to carry out the Development Program during such initial term. However,
if due to unforseen circumstances unavoidable delays attributable solely to
Fuisz are encountered, or force majeure events are encountered in carrying out
activities, the initial term of the Development Program shall be extended for a
time equal to the delay at no additional cost to Kos. The Development Program
shall be automatically extended on a week by week basis after the initial term
provided that Kos may terminate the Development Program anytime after the
initial term or at the end of each successive weekly extension of the
Development Program, and Fuisz may terminate the Development Program at the end
of the ************** weekly extension thereof or at the end of each successive
weekly extension thereafter, respectively upon ********* calendar days advance
notice in writing to the other party.

2.2         If either party shall default, fail to perform, or otherwise commit
a breach of a material obligation or any covenant contained herein with respect
to the Development Program, and shall fail to remedy such default, failure to
perform or breach within ********** days after its receipt of written notice
thereof from the other party, such other party may terminate the Development
Program and incur no further obligation hereunder, it being understood, however,
that if within such ********** days after receipt of such notice, the party in
default shall have rectified its default, then the Development Program and the
terms hereof relating to the Development Program shall be restored as if no
termination of the Development Program had occurred. The term of this Agreement
(or any extension thereof) shall be tolled by the time required by the
defaulting party to cure the default.

                                        3


<PAGE>

2.3         This Agreement shall commence upon the Effective Date and terminate
at the end of the term of the Development Program, including any extensions
thereof.

2.4         Except for Kos and Fuisz jointly owned technology and patents and
Fuisz solely owned technology and patents, Fuisz hereby acknowledges that it
shall not have the right, following expiration of the Development Agreement
term, to use technology to the extent obtained from Kos, patents based thereon
or any materials to the extent obtained from Kos, for any purpose without
obtaining a license from Kos, which license Kos, in its sole discretion, may
grant or deny.

2.5         Except as set forth in the License Agreement and except for Kos and
Fuisz jointly owned technology and patents and Kos solely owned technology and
patents, Kos hereby acknowledges that it shall not have the right, following
expiration of the Development Agreement term, to use Technology to the extent
obtained from Fuisz, patents based thereon or any materials to the extent
obtained from Fuisz, for any purpose without obtaining a license from Fuisz,
which license Fuisz, in its sole discretion, may grant or deny.

ARTICLE 3 - FUNDING OF THE DEVELOPMENT PROGRAM

3.1         Kos shall provide total funding for Phase 1 of the Development
Program as set forth in Appendix B, in the amount of
****************************
******************************************************************************
******************* of which shall be paid to Fuisz within *********** days of
the Effective Date, and ******************************** of which shall be paid
within ************************ following the end of Phase 1 and
****************************************** of which shall be paid within
**************** following completion of the Phase 1 ******************* of
Appendix B. This amount of funding may be increased by mutual agreement. This
funding shall not include the cost of the ******************* which shall be
funded and paid for ************. In the event Kos chooses to proceed to Phase 2
and/or Phase 3 as set forth in Appendix B, unless Fuisz determines further
development is not feasible, Kos shall pay to Fuisz additional amounts
commensurate with the activity involved and as mutually agreed, consistent with
the cost of Phase 1 and with the level of activity, for Phase 2 and for Phase 3
payable within **************** of commencement of the phases.

3.2         In the event the Development Program is extended by mutual written
agreement of the parties, each successive one (1) week extension after the
initial term shall be funded and paid to Fuisz in advance at a rate of
************************************ per week with respect to extension of Phase
I, and with respect to Phases 2 and 3, such weekly amounts as are consistent
with the additional funding set forth in Section 3.1; provided, however, that if
the man-day charges for

                                        4


<PAGE>

work carried out at Fuisz during the initial term are less than the funding
actually paid under the initial term (exclusive of charges under Section 1.8)
then additional funding for such extensions under this Section 3.2 shall not be

respective contributions to the costs and expenses incurred in such action.

7.3         INFRINGEMENT ACTION BY THIRD PARTIES

                  (a) In the event of the institution of any suit by a third
party against Kos for patent infringement involving the manufacture, use, sale,
distribution or marketing of any Licensed Product, provided the basis of such
suit is the practice by Kos of a Licensed Patent or Technology licensed
hereunder, Kos shall promptly notify Fuisz in writing of such suit. Kos shall
have the right to defend such suit at its own expense, and Fuisz shall assist
and cooperate with Kos, at Kos's expense, to the extent necessary in the defense

held not to be infringing any patents belonging to such third party or because
such third party's patent is held invalid, Kos shall continue to pay royalty as
set forth in Article 4, ***
******************************************************************************
******************************************************************************
******************************************************************************
***************************************************************.

                  (c) If Kos finally loses in any such infringement action,

royalty as set forth in Article 4 with respect to such Licensed Product in the
country which is the subject of such action,

information or trade secrets to such Affiliate, agent or consultant shall notify
the other party of the identity of such Affiliate, agent or consultant, and
provide the other party with a draft of the proposed confidentiality agreement
with such Affiliate, agent or consultant and allow the other party to make
