                               THE COMPANY

Principal Executive     Science Dynamics Corporation
Offices:                1919 Springdale Road
                        Cherry Hill, New Jersey 08003-1069
                        (856) 424-0068

Our Business:

     Science Dynamics Corporation was incorporated in the State of Delaware
May 1973 and commenced operations in July 1977.  During the past 21 years we
have developed, designed and marketed a variety of Telecommunications systems,
including intelligent call processing platforms which provide
telecommunications service capabilities to the public switched telephone
network. These platforms are sophisticated software based systems, which
satisfy a wide range of computer telephony integration applications.  In
November 1996, we acquired the intellectual property of Innovative
Communications Technology (ICT) and under the direction of Alan C. Bashforth,
the then-new CEO/President embarked on transforming Science Dynamics into a
predominately software design and system integration Company.  On February 18,
2000, our Executive Vice President, Secretary, Treasurer and CFO, Joy Hartman,
was additionally appointed to the position of President and CEO.
Alan C. Bashforth assumed the position of Vice Chairman of the Board of
Directors, and will also serve as a consultant.

    Over the past two years, the challenge was to expand the product offerings
and migrate into additional markets within the Computer Telephony Integration
(CTI) industry.  We believe that communicating via packet networks such as
ATM and Frame Relay, is becoming the preferred strategy for both public
networks and business enterprises. Our focus is to address niche market
opportunities in Data Network Companies, Telephone Service Distributors and
Regional Bell Operating Companies (RBOC's), such as BellSouth, Ameritech,
US West, Southwestern Bell and large independent telephone operating
companies, such as GTE, Sprint and Citizens.


    Our development is driven by user needs for cost effective, easy to use
multiservice products that provide an array of telecommunications solutions
and services to the customers.  These opportunities are primarily in the
areas of Voice over Internet Protocol, Inmate Systems, Video over Frame Relay,
Voice Announcements, Interactive Communications, Intelligent Network Control
and Administration. Our strategy today is to deliver quality software
products and services that empower its customers to improve their
applications and deploy quality services worldwide.

BUSINESS DEVELOPMENT
---------------------

    Science Dynamics has focused its strategy to be a provider of key enabling
technologies required for the convergence of traditional and new communications
media and infrastructures.

                                       -4-
<PAGE>


    Communications media today must include traditional Telephony (an area for
which Science Dynamics has 21 years experience), Data services (to include the
Internet) and Video services.  Current infrastructures based on PDH
(Plesiochronous Digital Hierarchy) technology are quickly being replaced with
SDH (Synchronous Digital Hierarchy) technologies more suited to larger
bandwidth packet data transmissions.


    Management believes communicating via packet data networks such as
IP(Internet Protocol), ATM (Asynchronous Transfer Mode), and Frame Relay is
becoming a preferred strategy for both corporate and public network planners.
Predictions have been made that data traffic will soon exceed telephone
traffic. At the same time, more and more companies are seeing the value of
transporting voice and fax over data networks to reduce telephone and
facsimile costs and to set the stage for advanced multimedia applications.

    IP's ability to run over any network medium has led to its widespread
adoption around the world. Its popularity, though, goes far beyond the
Internet, to encompass the majority of data networks worldwide. Providing
high quality telephony over IP networks is one of the key steps in the
convergence of voice, fax, video, and data communications services.

    Science Dynamics has now proven IP Telephony to be both feasible and cost
effective with several customer trials.  New products, such as the
IntegratorC-2400(r) Gatekeeper, will continue to play a very important role
in positioning SDC in this fast growing market.

                                RISK FACTORS

WE HAVE HAD LOSSES AND THERE MAY BE FURTHER LOSSES

    We incurred net losses of $1,022,030 for the year ended December 31, 1997
and $1,036,306 for the year ended December 31, 1998.  We cannot assure you
that we can sustain or increase profitability on a quarterly or annual basis
in the future.  If revenues grow more slowly than we anticipate, or if
operating expenses exceed our expectations or cannot be adjusted accordingly,
our business, results of operations and financial condition will be materially
and adversely affected.
                                       -5-
<PAGE>

OUR MARKETS ARE COMPETITIVE


Due to the diversified nature of the products and target markets, our
competition varies greatly by product line.  Our Inmate Products division
holds a respectable portion of the Inmate market with the Commander system.
We compete against three other primary vendors in this area but the system
captures a sizable share of the target market.

We have limited competition in the Video-Over-Frame market.  Competing
products include integrated Frame Relay Codec, an ISDN over Frame Relay
product and the use of H.323 packetized LAN Video, a different concept which
crosses into our market.

Our IP products will compete in a marketplace that is populated by larger
companies who have significantly more resources for development, marketing
and deployment.  We may not be able to compete successfully against current
or future competitors, and competitive pressures could significantly harm us.

RISKS OF BUSINESS COMBINATIONS AND STRATEGIC ALLIANCES

We may expand our operations or market presence by entering into business
combinations, investments, joint ventures or other strategic alliances with
other companies. These transactions create risks such as:

   - Difficulty assimilating the operations, technology and personnel
     of the combined companies,
   - Disruption of our ongoing business,
   - Problems retaining key technical and managerial personnel,
   - Expenses associated with amortization of goodwill and other
     purchased intangible assets,
   - Additional operating losses and expenses of acquired
     businesses, and
   - Impairment of relationships with existing employees,
     customers and business partners.

We may not succeed in addressing these risks.

WE MAY NEED ADDITIONAL FUNDS TO EXPAND OUR SALES AND MARKETING ACTIVITIES,
RESEARCH AND DEVELOPMENT, AND STRATEGIC ALLIANCES.


Based on current levels of operations and planned growth, we anticipate that
our existing capital resources, together with cash generated from operations
will enable us to maintain our operations for the next 12 months. We may
require additional funds to sustain and expand our sales and marketing
activities, research and development, and our strategic alliances,
particularly if a well-financed competitor emerges or if there is a rapid
technological shift in the telecommunications industry.  There can be no
assurance that financing will be available in amounts or on terms acceptable
to us, if at all. The inability to obtain sufficient funds from operations
and external sources would have a material adverse effect on our business.

                                       -6-
<PAGE>
WE DEPEND ON KEY PERSONNEL.


We depend on the continues services and on performance of our senior
management and other key personnel, particularly Joy C. Hartman, our
President, CEO, Secretary, Treasurer and Chief Financial Officer, and
Alan C. Bashforth, our Vice Chairman of the Board of Directors and
Consultant. Our success also depends on our ability to retain and motivate
our other officers and key employees. The loss of the services of any of our
executive officers or other key employees could harm our business. We have
employment agreements with only two of our key personnel, our President and
Chief Financial Officer.  Our future success also depends on our ability to
attract and retain and motivate other highly skilled engineering, technical,
sales, marketing and customer service personnel. Competition for such
personnel is intense, and there can be no assurance that we will be able to
successfully attract, assimilate or retain sufficiently qualified personnel
which could harm our business.

WE ARE RELIANT UPON CERTAIN SUPPLIERS, THE LOSS OF ANY OF WHICH COULD BE
DISRUPTIVE TO OUR BUSINESS, REDUCE OUR OPPORTUNITIES FOR PROFITABILITY AND
CAUSE THE PRICE OF OUR STOCK TO FALL.

Although most of the components used in our products are available from a
number of different suppliers on an off-the-shelf basis, certain components
are purchased from sole source suppliers.  If such a supplier should cease to
deliver a component, another source would have to be developed.  Acquiring a
substitute part or module may require a hardware or software change in the
unit in order to provide satisfactory performance, adding costs and delays of
unknown amount and duration.

OUR REVENUES ARE GENERATED AMONG A RELATIVELY SMALL NUMBER OF CUSTOMERS. THE
LOSS OF ANY ONE OR MORE OF THESE CUSTOMERS WOULD GREATLY REDUCE OUR
OPPORTUNITIES TO ACHIEVE AND SUSTAIN PROFITABILITY AND MAY CAUSE A REDUCTION
IN THE MARKET PRICE OF OUR STOCK.

A majority of our sales have been attributable to a relatively small number
of customers.  For example, our major customers, independent and Bell
Operating Companies, accounted for 82.95%, 4.69% and 3.45% of total revenue
in 1998. If one or more of our large-volume customers were to discontinue
doing business with us, our results of operations would be materially and
adversely affected.  In addition, the irregular timing of large orders and
their materiality to our total revenues for any given reporting period has
caused, and is expected to cause, substantial volatility in our operating
results.  However, with the introduction of the new product lines, we have
expanded our customer base globally and should be less reliant on any single
market or territory.


WE MAY BE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY

    We regard substantial elements of our products as proprietary and attempt
to protect them by relying on patent, trademark, service mark, trade dress,
copyright, and trade secret laws and restrictions, as well as confidentiality
procedures and contractual provisions.  Any steps we take to protect our
intellectual property may be inadequate, time consuming, and expensive. In
addition, despite our efforts, we may be unable to prevent third-parties from
infringing upon or misappropriating our intellectual property.  Any such
infringement or misappropriation could have a material adverse effect on our
business, results of operations, and financial condition.  Currently issued
patents or any new patent applications may not provide us with any
competitive advantages, or may be challenged by third parties.  Effective
trademark, copyright, and trade secret protection may not be available in
every country in which our products are distributed.  In addition, our
competitors may independently develop similar technology that substantially
limits the value of our intellectual property.

                                       -7-
<PAGE>

OTHERS MAY BRING INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS AGAINST US

    In addition to the technology we have developed internally, we also have
acquired or licensed technologies from other companies.  Our internally
developed technology or the technology we acquired or licensed may infringe
on a third party's intellectual property rights and such third parties may
bring claims against us alleging infringement of their intellectual property
rights. Any such infringement or claim of infringement could have a material
adverse affect on our business, result of operations, and financial condition.

    In recent years, there has been significant litigation in the United
States involving patents and other intellectual property rights.  We are not
currently involved in any intellectual property litigation.  We may, however,
be a party to litigation in the future to protect our intellectual property
or as a result of an alleged infringement of others' intellectual property.
Such claims and any resulting litigation could subject us to significant
liability for damages and invalidation of our proprietary rights.  Such
litigation, regardless of its success, likely would be time-consuming and
expensive to defend and would divert management time and attention.  Any
potential intellectual property litigation could also force us to do one or
more of the following:

     - Cease selling, incorporating, or using products or services
        that incorporate the challenged intellectual property;

     - Obtain from the holder of the infringed intellectual property
        right a license to sell or use the relevant technology, which
        license may not be available on reasonable terms, or at all; and

     - Redesign those products or services that incorporate such
        technology.

Any of these results could have a material adverse effect on our business,
results of operations, and financial condition.


WE MAY NEVER PAY DIVIDENDS ON OUR COMMON STOCK, IN WHICH EVENT PURCHASERS'
ONLY RETURN ON THEIR INVESTMENT, IF ANY, WILL OCCUR ON THE SALE OF OUR STOCK.
We have never declared or paid a cash dividend.  We presently intend to retain
any future earnings for use in the business and do not presently intend to
pay cash dividends in the foreseeable future.

INDEMNIFICATION AND LIMITATION OF LIABILITY OF OUR OFFICERS AND DIRECTORS MAY
INSULATE THEM FROM ACCOUNTABILITY TO STOCKHOLDERS AT SUBSTANTIAL COST TO
SCIENCE DYNAMICS


    Our by-laws include provisions whereby our officers and directors are to
be indemnified against liabilities to the fullest extent permissible under
Delaware law.  Our by-laws also limit a director's liability for monetary
damages for breach of fiduciary duty, including gross negligence. In addition,
we have agreed to advance the legal expenses of our officers and directors
who are required to defend against claims.  These provisions and agreements
may have the effect of reducing the likelihood of suits against directors and
officers even though such suits, if successful, might benefit us and our
stockholders.  Furthermore, your investment in may be adversely affected if
we pay the cost of settlement and damage awards against directors and officers.

                                       -8-
<PAGE>

A LARGE BLOCK OF SHARES CAN BE SOLD UNDER RULE 144.

Owners of a large block of shares which were previously restricted can be
sold under Rule 144.  The sale of a large number of these shares could lower
the price of our shares or make it harder to attract new investors.

(i.e., the total  number of Shares  underlying  options  held by the  selling
shareholders irrespective  of whether such options are presently exercisable
or exercisable within sixty days of January 14, 2000) and (iii) the number
and percentage of shares of Common Stock to be held by each Selling
Shareholder after completion of the offering. The table is based upon

                    DISCLOSURE OF COMMISSION POSITION ON
               INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

    Section 145 of the General Corporation Law of Delaware grants each
corporation organized thereunder the power to indemnify its officers,
directors, employees and agents on certain conditions against liabilities
arising out of any action or proceeding to which any of them is a party by
reason of being such officer, director, employee or agent.  The Certificate
of Incorporation also provides for the indemnification, to the fullest extent
permitted by the General Corporation Law of Delaware, of such persons.
Insofar as indemnification for liabilities arising under the Securities Act,
may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provisions, the Company has been informed that in
the opinion of the Commission such indemnification is against public policy
as expressed in the Securities Act and is therefore unenforceable.

                                  LEGAL MATTERS

    Certain legal matters in  connection  with the issuance of the Shares
offered hereby have been passed upon for the Company by Stephen M. Robinson,
P.A., 172 Tuckerton Road, Medford, New Jersey, 08055.

ITEM 9.  UNDERTAKINGS.

(a)  The undersigned registrant hereby undertakes:

    (1)  To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

      (i)  To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

      (ii)  To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the
registration statement;

      (iii)  To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Securities and Exchange Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the registration statement.

    (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

    (3)  To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination
of the offering.

(b)  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of
the Securities Exchange Act of 1934 (and, where applicable, each filing of
an employee  benefit plan's annual report pursuant to Section 15(d)  of the
Securities Exchange Act of 1934) that is incorporated by reference in  the
registration statement shall be deemed to be a new registration  statement
relating to the securities offered therein, and the offering of  such
securities at that time shall be deemed to be the initial bona fide
offering thereof.

(h)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions,
or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable.  In the
event that a claim for indemnification against such liabilities (other than
the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

         Re:  Science Dynamics Corporation
              REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

      We have acted as counsel to Science Dynamics Corporation, a Delaware
corporation (the "Company"), in connection with the registration of
1,088,000 shares of common stock, $.01 par value (the "Shares"), with the
Securities and Exchange Commission (the "Commission") under the Securities
Act of 1933, as amended (the "1933 Act") pursuant to a registration
statement on Form S-8 (the "Registration Statement").  The Shares are
registered on behalf of the Company and will be issued pursuant to the
Company's 1992 Incentive Stock Option Plan (the "Plan").

         This opinion is being delivered in accordance with the requirements
of Item 601(b)(5)(i) of Regulation S-B under the 1933 Act.

         As counsel to the Company, we have examined such documents and
records as we deemed appropriate.

         In rendering this opinion, we have relied, as to matters of fact,
upon representations and certificates of officers and employees of the
Company, and communications from, government authorities and public
officials; and we have assumed the genuineness of signatures of all persons
signing any documents, the authority of all persons signing any document,
the authority of all governmental authorities and public officials, the
truth and accuracy of all matters of fact set forth in all certificates
furnished to us, the authenticity of all documents submitted to us as
originals and the conformity to original documents of all documents
submitted to us as certified, conformed or photostatic copies.

         Based upon the foregoing, we are of the opinion that the Shares
issuable upon exercise of options issued under the Plan, when issued and
delivered upon exercise of such options in accordance with the terms of the
Plan, will be validly issued, fully paid and non-assessable.

         This opinion is solely for your information in connection with the
offer and sale of the Shares by the Company, and is not, without the prior
written consent of this firm, to be quoted in full or in part or otherwise
referred to in any documents nor to be filed with any governmental agency or
other persons, other than with the Commission and various state securities

administrators in connection with the qualification of the Shares, to which
reference and filings we hereby consent.  In giving this consent, we do not
thereby admit that we are in the category of persons whose consent is
required under Section 7 of the 1933 Act or the rules and regulations of the
Commission.


                                  Very truly yours,

                                  STEPHEN M. ROBINSON, P.A.

                                  /s/ Stephen M. Robinson

                               THE COMPANY

Principal Executive     Science Dynamics Corporation
Offices:                1919 Springdale Road
                        Cherry Hill, New Jersey 08003-1069
                        (856) 424-0068

Our Business:

     Science Dynamics Corporation was incorporated in the State of Delaware
May 1973 and commenced operations in July 1977.  During the past 21 years we
have developed, designed and marketed a variety of Telecommunications systems,
including intelligent call processing platforms which provide
telecommunications service capabilities to the public switched telephone
network. These platforms are sophisticated software based systems, which
satisfy a wide range of computer telephony integration applications.  In
November 1996, we acquired the intellectual property of Innovative
Communications Technology (ICT) and under the direction of Alan C. Bashforth,
the then-new CEO/President embarked on transforming Science Dynamics into a
predominately software design and system integration Company.  On February 18,
2000, our Executive Vice President, Secretary, Treasurer and CFO, Joy Hartman,
was additionally appointed to the position of President and CEO.
Alan C. Bashforth assumed the position of Vice Chairman of the Board of
Directors, and will also serve as a consultant.

    Over the past two years, the challenge was to expand the product offerings
and migrate into additional markets within the Computer Telephony Integration
(CTI) industry.  We believe that communicating via packet networks such as
ATM and Frame Relay, is becoming the preferred strategy for both public
networks and business enterprises. Our focus is to address niche market
opportunities in Data Network Companies, Telephone Service Distributors and
Regional Bell Operating Companies (RBOC's), such as BellSouth, Ameritech,
US West, Southwestern Bell and large independent telephone operating
companies, such as GTE, Sprint and Citizens.

    Our development is driven by user needs for cost effective, easy to use
multiservice products that provide an array of telecommunications solutions
and services to the customers.  These opportunities are primarily in the
areas of Voice over Internet Protocol, Inmate Systems, Video over Frame Relay,
Voice Announcements, Interactive Communications, Intelligent Network Control
and Administration. Our strategy today is to deliver quality software
products and services that empower its customers to improve their
applications and deploy quality services worldwide.

BUSINESS DEVELOPMENT
---------------------

    Science Dynamics has focused its strategy to be a provider of key enabling
technologies required for the convergence of traditional and new communications
media and infrastructures.

                                       -4-
Communications media today must include traditional Telephony (an area for
which Science Dynamics has 21 years experience), Data services (to include the
Internet) and Video services.  Current infrastructures based on PDH
(Plesiochronous Digital Hierarchy) technology are quickly being replaced with
SDH (Synchronous Digital Hierarchy) technologies more suited to larger
bandwidth packet data transmissions.

    Management believes communicating via packet data networks such as
IP(Internet Protocol), ATM (Asynchronous Transfer Mode), and Frame Relay is
becoming a preferred strategy for both corporate and public network planners.
Predictions have been made that data traffic will soon exceed telephone
traffic. At the same time, more and more companies are seeing the value of
transporting voice and fax over data networks to reduce telephone and
facsimile costs and to set the stage for advanced multimedia applications.

    IP's ability to run over any network medium has led to its widespread
adoption around the world. Its popularity, though, goes far beyond the
Internet, to encompass the majority of data networks worldwide. Providing
high quality telephony over IP networks is one of the key steps in the
convergence of voice, fax, video, and data communications services.

    Science Dynamics has now proven IP Telephony to be both feasible and cost
effective with several customer trials.  New products, such as the
IntegratorC-2400(r) Gatekeeper, will continue to play a very important role
in positioning SDC in this fast growing market.

                                RISK FACTORS

WE HAVE HAD LOSSES AND THERE MAY BE FURTHER LOSSES

    We incurred net losses of $1,022,030 for the year ended December 31, 1997
and $1,036,306 for the year ended December 31, 1998.  We cannot assure you
that we can sustain or increase profitability on a quarterly or annual basis
in the future.  If revenues grow more slowly than we anticipate, or if
operating expenses exceed our expectations or cannot be adjusted accordingly,
our business, results of operations and financial condition will be materially
and adversely affected.
                                       -5-
OUR MARKETS ARE COMPETITIVE

Due to the diversified nature of the products and target markets, our
competition varies greatly by product line.  Our Inmate Products division
holds a respectable portion of the Inmate market with the Commander system.
We compete against three other primary vendors in this area but the system
captures a sizable share of the target market.

We have limited competition in the Video-Over-Frame market.  Competing
products include integrated Frame Relay Codec, an ISDN over Frame Relay
product and the use of H.323 packetized LAN Video, a different concept which
crosses into our market.

Our IP products will compete in a marketplace that is populated by larger
companies who have significantly more resources for development, marketing
and deployment.  We may not be able to compete successfully against current
or future competitors, and competitive pressures could significantly harm us.

RISKS OF BUSINESS COMBINATIONS AND STRATEGIC ALLIANCES

We may expand our operations or market presence by entering into business
combinations, investments, joint ventures or other strategic alliances with
other companies. These transactions create risks such as:

   - Difficulty assimilating the operations, technology and personnel
     of the combined companies,
   - Disruption of our ongoing business,
   - Problems retaining key technical and managerial personnel,
   - Expenses associated with amortization of goodwill and other
     purchased intangible assets,
   - Additional operating losses and expenses of acquired
     businesses, and
   - Impairment of relationships with existing employees,
     customers and business partners.

We may not succeed in addressing these risks.

WE MAY NEED ADDITIONAL FUNDS TO EXPAND OUR SALES AND MARKETING ACTIVITIES,
RESEARCH AND DEVELOPMENT, AND STRATEGIC ALLIANCES.

Based on current levels of operations and planned growth, we anticipate that
our existing capital resources, together with cash generated from operations
will enable us to maintain our operations for the next 12 months. We may
require additional funds to sustain and expand our sales and marketing
activities, research and development, and our strategic alliances,
particularly if a well-financed competitor emerges or if there is a rapid
technological shift in the telecommunications industry.  There can be no
assurance that financing will be available in amounts or on terms acceptable
to us, if at all. The inability to obtain sufficient funds from operations
and external sources would have a material adverse effect on our business.

                                       -6-
WE DEPEND ON KEY PERSONNEL.

We depend on the continues services and on performance of our senior
management and other key personnel, particularly Joy C. Hartman, our
President, CEO, Secretary, Treasurer and Chief Financial Officer, and
Alan C. Bashforth, our Vice Chairman of the Board of Directors and
Consultant. Our success also depends on our ability to retain and motivate
our other officers and key employees. The loss of the services of any of our
executive officers or other key employees could harm our business. We have
employment agreements with only two of our key personnel, our President and
Chief Financial Officer.  Our future success also depends on our ability to
attract and retain and motivate other highly skilled engineering, technical,
sales, marketing and customer service personnel. Competition for such
personnel is intense, and there can be no assurance that we will be able to
successfully attract, assimilate or retain sufficiently qualified personnel
which could harm our business.

WE ARE RELIANT UPON CERTAIN SUPPLIERS, THE LOSS OF ANY OF WHICH COULD BE
DISRUPTIVE TO OUR BUSINESS, REDUCE OUR OPPORTUNITIES FOR PROFITABILITY AND
CAUSE THE PRICE OF OUR STOCK TO FALL.

Although most of the components used in our products are available from a
number of different suppliers on an off-the-shelf basis, certain components
are purchased from sole source suppliers.  If such a supplier should cease to
deliver a component, another source would have to be developed.  Acquiring a
substitute part or module may require a hardware or software change in the
unit in order to provide satisfactory performance, adding costs and delays of
unknown amount and duration.

OUR REVENUES ARE GENERATED AMONG A RELATIVELY SMALL NUMBER OF CUSTOMERS. THE
LOSS OF ANY ONE OR MORE OF THESE CUSTOMERS WOULD GREATLY REDUCE OUR
OPPORTUNITIES TO ACHIEVE AND SUSTAIN PROFITABILITY AND MAY CAUSE A REDUCTION
IN THE MARKET PRICE OF OUR STOCK.

A majority of our sales have been attributable to a relatively small number
of customers.  For example, our major customers, independent and Bell
Operating Companies, accounted for 82.95%, 4.69% and 3.45% of total revenue
in 1998. If one or more of our large-volume customers were to discontinue
doing business with us, our results of operations would be materially and
adversely affected.  In addition, the irregular timing of large orders and
their materiality to our total revenues for any given reporting period has
caused, and is expected to cause, substantial volatility in our operating
results.  However, with the introduction of the new product lines, we have
expanded our customer base globally and should be less reliant on any single
market or territory.

WE MAY BE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY

    We regard substantial elements of our products as proprietary and attempt
to protect them by relying on patent, trademark, service mark, trade dress,
copyright, and trade secret laws and restrictions, as well as confidentiality
procedures and contractual provisions.  Any steps we take to protect our
intellectual property may be inadequate, time consuming, and expensive. In
addition, despite our efforts, we may be unable to prevent third-parties from
infringing upon or misappropriating our intellectual property.  Any such
infringement or misappropriation could have a material adverse effect on our
business, results of operations, and financial condition.  Currently issued
patents or any new patent applications may not provide us with any
competitive advantages, or may be challenged by third parties.  Effective
trademark, copyright, and trade secret protection may not be available in
every country in which our products are distributed.  In addition, our
competitors may independently develop similar technology that substantially
limits the value of our intellectual property.

                                       -7-
OTHERS MAY BRING INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS AGAINST US

    In addition to the technology we have developed internally, we also have
acquired or licensed technologies from other companies.  Our internally
developed technology or the technology we acquired or licensed may infringe
on a third party's intellectual property rights and such third parties may
bring claims against us alleging infringement of their intellectual property
rights. Any such infringement or claim of infringement could have a material
adverse affect on our business, result of operations, and financial condition.

    In recent years, there has been significant litigation in the United
States involving patents and other intellectual property rights.  We are not
currently involved in any intellectual property litigation.  We may, however,
be a party to litigation in the future to protect our intellectual property
or as a result of an alleged infringement of others' intellectual property.
Such claims and any resulting litigation could subject us to significant
liability for damages and invalidation of our proprietary rights.  Such
litigation, regardless of its success, likely would be time-consuming and
expensive to defend and would divert management time and attention.  Any
potential intellectual property litigation could also force us to do one or
more of the following:

     - Cease selling, incorporating, or using products or services
        that incorporate the challenged intellectual property;

     - Obtain from the holder of the infringed intellectual property
        right a license to sell or use the relevant technology, which
        license may not be available on reasonable terms, or at all; and

     - Redesign those products or services that incorporate such
        technology.

Any of these results could have a material adverse effect on our business,
results of operations, and financial condition.

WE MAY NEVER PAY DIVIDENDS ON OUR COMMON STOCK, IN WHICH EVENT PURCHASERS'
ONLY RETURN ON THEIR INVESTMENT, IF ANY, WILL OCCUR ON THE SALE OF OUR STOCK.
We have never declared or paid a cash dividend.  We presently intend to retain
any future earnings for use in the business and do not presently intend to
pay cash dividends in the foreseeable future.

INDEMNIFICATION AND LIMITATION OF LIABILITY OF OUR OFFICERS AND DIRECTORS MAY
INSULATE THEM FROM ACCOUNTABILITY TO STOCKHOLDERS AT SUBSTANTIAL COST TO
SCIENCE DYNAMICS

    Our by-laws include provisions whereby our officers and directors are to
be indemnified against liabilities to the fullest extent permissible under
Delaware law.  Our by-laws also limit a director's liability for monetary
damages for breach of fiduciary duty, including gross negligence. In addition,
we have agreed to advance the legal expenses of our officers and directors
who are required to defend against claims.  These provisions and agreements
may have the effect of reducing the likelihood of suits against directors and
officers even though such suits, if successful, might benefit us and our
stockholders.  Furthermore, your investment in may be adversely affected if
we pay the cost of settlement and damage awards against directors and officers.

                                       -8-
A LARGE BLOCK OF SHARES CAN BE SOLD UNDER RULE 144.

Owners of a large block of shares which were previously restricted can be
sold under Rule 144.  The sale of a large number of these shares could lower
the price of our shares or make it harder to attract new investors.

              Special Note Regarding Forward-looking Statements

    Some of the statements contained in this prospectus, including information
incorporated by reference, discuss future expectations, contain projections of
future results of operations or financial condition or state other
"forward-looking" information.  Those statements are subject to known and
unknown risks, uncertainties and other factors that could cause the actual
results to differ materially from those contemplated by the statements. The
forward-looking information is based on various factors and was derived using
numerous assumptions.  Important factors that may cause actual results to
differ from projections include the risk factors set forth above.

                                       -9-

DISCLOSURE OF COMMISSION POSITION ON
               INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

    Section 145 of the General Corporation Law of Delaware grants each
corporation organized thereunder the power to indemnify its officers,
directors, employees and agents on certain conditions against liabilities
arising out of any action or proceeding to which any of them is a party by
reason of being such officer, director, employee or agent.  The Certificate
of Incorporation also provides for the indemnification, to the fullest extent
permitted by the General Corporation Law of Delaware, of such persons.
Insofar as indemnification for liabilities arising under the Securities Act,
may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provisions, the Company has been informed that in
the opinion of the Commission such indemnification is against public policy
as expressed in the Securities Act and is therefore unenforceable.

                                  LEGAL MATTERS

    Certain legal matters in  connection  with the issuance of the Shares
offered hereby have been passed upon for the Company by Stephen M. Robinson,
P.A., 172 Tuckerton Road, Medford, New Jersey, 08055.

ITEM 9.  UNDERTAKINGS.

(a)  The undersigned registrant hereby undertakes:

    (1)  To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

      (i)  To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

      (ii)  To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the
registration statement;

      (iii)  To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Securities and Exchange Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the registration statement.

    (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

    (3)  To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination
of the offering.

(b)  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of
the Securities Exchange Act of 1934 (and, where applicable, each filing of
an employee  benefit plan's annual report pursuant to Section 15(d)  of the
Securities Exchange Act of 1934) that is incorporated by reference in  the
registration statement shall be deemed to be a new registration  statement
relating to the securities offered therein, and the offering of  such
securities at that time shall be deemed to be the initial bona fide
offering thereof.

(h)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions,
or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable.  In the
event that a claim for indemnification against such liabilities (other than
the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

         Re:  Science Dynamics Corporation
              REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

      We have acted as counsel to Science Dynamics Corporation, a Delaware
corporation (the "Company"), in connection with the registration of
1,088,000 shares of common stock, $.01 par value (the "Shares"), with the
Securities and Exchange Commission (the "Commission") under the Securities
Act of 1933, as amended (the "1933 Act") pursuant to a registration
statement on Form S-8 (the "Registration Statement").  The Shares are
registered on behalf of the Company and will be issued pursuant to the
Company's 1992 Incentive Stock Option Plan (the "Plan").

         This opinion is being delivered in accordance with the requirements
of Item 601(b)(5)(i) of Regulation S-B under the 1933 Act.

         As counsel to the Company, we have examined such documents and
records as we deemed appropriate.

         In rendering this opinion, we have relied, as to matters of fact,
upon representations and certificates of officers and employees of the
Company, and communications from, government authorities and public
officials; and we have assumed the genuineness of signatures of all persons
signing any documents, the authority of all persons signing any document,
the authority of all governmental authorities and public officials, the
truth and accuracy of all matters of fact set forth in all certificates
furnished to us, the authenticity of all documents submitted to us as
originals and the conformity to original documents of all documents
submitted to us as certified, conformed or photostatic copies.

         Based upon the foregoing, we are of the opinion that the Shares
issuable upon exercise of options issued under the Plan, when issued and
delivered upon exercise of such options in accordance with the terms of the
Plan, will be validly issued, fully paid and non-assessable.

         This opinion is solely for your information in connection with the
offer and sale of the Shares by the Company, and is not, without the prior
written consent of this firm, to be quoted in full or in part or otherwise
referred to in any documents nor to be filed with any governmental agency or
other persons, other than with the Commission and various state securities

administrators in connection with the qualification of the Shares, to which
reference and filings we hereby consent.  In giving this consent, we do not
thereby admit that we are in the category of persons whose consent is
required under Section 7 of the 1933 Act or the rules and regulations of the
Commission.

                                  Very truly yours,

                                  STEPHEN M. ROBINSON, P.A.

                                  /s/ Stephen M. Robinson

         As independent accountants, we hereby consent to the incorporation by
reference in this registration statement of our reports included in Science
Dynamics Corporation's Form 10-KSB for the years ended December 31, 1992,
1993, 1994, 1995, 1996, 1997 and 1998 and to all references to our Firm
