                          LIGHTPATH TECHNOLOGIES, INC.

     LightPath produces  GRADIUM(R) glass,  utilizes other optical materials and
specialized  optical  packaging  concepts to produce  products  that  manipulate
light, and performs  research and development for optical solutions in the fiber
telecommunications and traditional optics markets.

     WHAT IS GRADIUM GLASS?  GRADIUM glass is an optical  quality glass material
with  varying  refractive  indices,  capable  of  reducing  optical  aberrations
inherent  in  conventional  lenses  and  performing  with a  single  lens  tasks
traditionally  performed by multi-element  conventional lens systems. We believe
that GRADIUM  glass  lenses  provide  advantages  over  conventional  lenses for
certain applications.  By reducing optical aberrations,  we believe that GRADIUM
glass  lenses  can  provide  sharper  images,  higher  resolution,   less  image
distortion,  a wider  usable  field of view and a smaller  focal spot  size.  By
reducing the number of lenses in an optical  system,  GRADIUM  glass can provide
more efficient  light  transmission  and greater  brightness,  lower  production
costs, and a simpler,  smaller product.  Although other  researchers have likely
sought to produce optical quality lens material with properties  similar to that
of  GRADIUM  glass,  we are not  aware  of any  other  person  or firm  that has
developed a repeatable  manufacturing  process for producing  such material on a
prescribable  basis. To date,  LightPath has been issued eighteen US patents for
GRADIUM  glass  products and currently  has numerous  filed patent  applications
pending related to our GRADIUM glass materials  composition,  product design and
fabrication  processes for production.  Additional patent applications have been
filed  or  are  in  process  for  laser   fusion   techniques   and   fiberoptic
optomechanical  switch technologies.  We are continually  developing new GRADIUM
glass  materials with various  refractive  indexes and  dispersion  profiles and
products  for the  telecommunications  field such as  fiberoptic  optomechanical
switches, multiplexers, interconnects and cross-connects.

     TO WHAT INDUSTRIES ARE  LIGHTPATH'S  GRADIUM GLASS PRODUCTS BEING MARKETED?
We believe that GRADIUM glass and our other optical materials can potentially be
marketed for use in most optics and  optoelectronics  products.  During 1998, we
restructured  our internal  organization  and marketing  focus with the intended
purpose  of   serving   two   distinct   markets:   optoelectronics   and  fiber
telecommunications,  and traditional  optics (e.g.  lasers,  medical  equipment,
consumer optics, etc.).

     Optoelectronics  technologies  consist  of  an  overlap  of  photonics  and
electronics  and are key enablers of  "Information  Age"  technologies,  such as
fiber optic  communications,  optical  data  storage,  laser  printers,  digital
imaging, and sensors for machine vision and environmental  monitoring.  Prior to
1998, we targeted  various  optoelectronic  industry  market niches as potential
purchasers  of our GRADIUM  glass  products.  During  1998,  we began to develop
products for the emerging optoelectronics markets,  specifically in the areas of
fiber  telecommunications.  With the resolution of fiber optic issues concerning

packaging and alignment and utilizing advances made by LightChip,  an affiliate,
in the area of WDM  equipment,  we began to produce  and  demonstrate  a passive
optoelectronic  product, the single mode fiber collimator assembly.  During 1999
we  expanded  this  product  line  with  the  goal  of   demonstrating   to  the
telecommunication  optical  components  industry our ability to provide low cost
products  and provide  solutions  to their  telecom  needs.  For the nine months
ending March 31, 2000, the telecom product line represent  approximately  30% of
our product sales.

     For traditional optics, we initially  emphasized laser products because our
management  believed at that time that GRADIUM  lenses could have a  substantial
immediate  commercial  impact in laser products with a relatively  small initial
financial investment.  Generally, optical designers can substitute GRADIUM glass
components  from our standard line of products in lieu of existing  conventional
laser lens elements.  Lasers are presently used  extensively in a broad range of
consumer and commercial products,  including fiber optics,  robotics, wafer chip
inspection,  bar code reading, document reproduction and audio and video compact
disc machines.  Because GRADIUM glass can concentrate light  transmission into a
much smaller focal spot than  conventional  lenses,  we believe,  and customers'
test results confirm,  that GRADIUM glass has the ability to improve the current
standard of laser performance.  One of our distributors,  Permanova Lasersystems
AB of Sweden,  qualified GRADIUM YAG lenses into systems produced by Rofin-Sinar
GmbH, a significant  original  equipment  manufacturer (OEM) of high-powered CO2
and YAG lasers  headquartered in Germany. Our growth strategy is to increase our
emphasis on key laser market niches and  establish  the  necessary  products and
partnership  alliances to sell into Europe and Asia as well as the U.S.  market.
During fiscal 1999,  LightPath and Rodenstock  Prazisionsoptik GmbH (Rodenstock)
executed   an   agreement   to   transfer   to   Rodenstock    the    exclusive,
application-related  utilization and  distribution of GRADIUM lenses  throughout
the whole of Europe.  The  agreement  was for an initial  five-year  period.  We
believe  Rodenstock's  one hundred  years of experience in the field of advanced
optical  systems and over 6,000 employees  worldwide,  will be a strong asset to
the expansion of our presence in Europe. We have established  relationships with
eight  foreign  distributors.  We believe these  distributors  will enable us to
establish  and  maintain a presence  in foreign  and  domestic  markets  without
further  investment  in this  product  area.  In addition to laser  applications
through our printed and Internet  on-line  catalog,  we offer a standard line of
GRADIUM  glass  lenses  for  commercial  sales to optical  designers  developing
particular  systems for OEMs or in-house  products.  For the nine months  ending
March 31, 2000, the traditional optics product line represent  approximately 70%
our of product sales.

     HOW HAS LIGHTPATH  DEVELOPED GRADIUM GLASS PRODUCTS?  From our inception in
1985 until June 1996, we were classified as a development  stage enterprise that
engaged in basic research and  development.  We believe that most of our product
sales  made  during  this  period  were to  persons  evaluating  the  commercial
application of GRADIUM glass or using the products for research and development.
During  fiscal year 1997,  our  operational  focus begin to shift to  commercial
product  development and sales. We completed numerous  prototypes for production
orders  and  received  our first  orders  for  catalog  sales of  standard  lens
profiles.  We also began to offer standard,  computer-based  profiles of GRADIUM
glass that engineers use for product design. During fiscal 1998, sales of lenses
to the traditional  optics market continued with significant  increases in sales
of lenses used in the YAG laser  market,  catalog  and  distributor  sales,  and

                                       2

lenses used in the wafer inspection  markets. In fiscal year 1998, we also began
to  explore  the   development   of  products  for  emerging   markets  such  as
optoelectronics,  photonics  and solar  energy  due to the  number of  potential
customers'  inquiries into the ability of GRADIUM glass to solve  optoelectronic
problems, specifically in the areas of fiber telecommunications.  Our resolution
of packaging and alignment issues, and advances made by LightChip, an affiliate,
with WDM  equipment,  led us in 1998 to  develop a  strategy  for  entering  the
optoelectronic  markets. Our first passive optoelectronic product, a single mode
fiber collimator assembly,  or SMF assembly,  was demonstrated in February 1998.
The SMF  assembly  is a key element in all fiber optic  systems,  including  WDM
equipment.  The SMF assembly straightens and makes parallel,  diverging light as
it exits a  fiber.  Beginning  in  fiscal  1999,  we  began  offering,  and have
delivered  for  testing  to  potential  customers,  three  product  levels:  the
collimating lens, the SMF assembly and the large beam collimating assembly.  The
telecommunications  collimator  marketplace  is currently  estimated by industry
experts to have  generated  annual  gross  revenues of $125 million in 1999 with
projected growth to $256 million in five years.

     The current focus of our development  group has been to expand  application
of  GRADIUM  products  to  the  areas  of  fiberoptic  optomechanical  switches,
multiplexers, interconnects and cross-connects for the telecommunications field,
further  refinement of the crown glass  product line to supplement  our existing
flint products,  and further  development of acrylic axial gradient  material to
extend the range of existing product applications.

FORWARD-LOOKING STATEMENTS

     Throughout  this  prospectus  and  the  other  documents   incorporated  by
reference  into this  prospectus we make certain  "forward-looking"  statements.
These are statements about future events,  results of operation,  business plans
and other  matters.  We use words such as  "expect",  "anticipate",  "intend" or
other similar words to identify forward looking statements. These statements are
made based on our current knowledge and understanding.  However, there can be no
assurances  as to whether or not actual  results will be  consistent  with these
statements. In fact, actual events or results could vary dramatically from these
statements as a result of among other factors:

     +    Economic conditions, domestically and internationally

     +    Technological developments

     +    Industry trends

     +    Risk factors described in this prospectus.

     We have no obligation to update the forward-looking statements made in this

                                  RISK FACTORS

     THE FOLLOWING SUMMARY SHOULD BE READ BY YOU TOGETHER WITH THE MORE DETAILED
INFORMATION  INCLUDED AT OTHER  SECTIONS OF THIS  PROSPECTUS.  IN ADDITION,  YOU
SHOULD CAREFULLY  CONSIDER THE FACTORS DESCRIBED UNDER "RISK FACTORS"  BEGINNING
AT PAGE 6 OF THIS PROSPECTUS.  OUR FISCAL YEAR ENDS ON JUNE 30 AND REFERENCES TO
YEARS IN THIS  PROSPECTUS  REFER TO OUR  FISCAL  YEAR ENDED AS OF JUNE 30 OF THE
REFERENCED CALENDAR YEAR.

WE HAVE EXPERIENCED LOSSES IN PRIOR YEARS.

     Our operations have never been profitable. We believe that our introduction
of  products  for the  telecommunication  market in 1999 may  generate  sales in
excess of amounts  realized to date,  although there can be no assurance in this
regard.  We expect to continue  operating at a deficit during the current fiscal
year and  until  such  time,  if ever,  as our  operations  generate  sufficient
revenues to cover our costs.  The  likelihood of our  financial  success must be
considered  in  light  of the  delays,  uncertainties,  difficulties  and  risks
inherent  in a new  business,  many of which are beyond our  ability to control.
These risks include, but are not limited to, unanticipated  problems relating to
product  development,  testing,  manufacturing,  marketing and competition,  and
additional costs and expenses that may exceed our current  estimates.  There can
be no assurance that our revenues will increase  significantly  in the future or
that, even if they do increase, our operations will ever be profitable.

WE MAY BE UNABLE TO CONTINUE OPERATING AS A GOING CONCERN.

     Our  June  30,  1999  financial  statements  received  a  report  from  our
independent   auditors  that  includes  an   explanatory   paragraph   regarding
uncertainty as to our ability to continue as a going concern.  The factors cited
by the auditors as raising  substantial doubt as to our ability to continue as a
going concern are our recurring  losses from operations and resulting  continued
dependence  on  external  sources  of  capital.  We may  incur  losses  for  the
foreseeable future due to the significant costs associated with the development,
manufacturing  and marketing of our products and due to the  continued  research
and  development  activities  that  will be  necessary  to  further  refine  our
technology and products and to develop products with additional applications.

WE  ANTICIPATE  THE NEED FOR  ADDITIONAL  FUTURE  FINANCING IN ORDER TO FUND OUR
OPERATIONS AND PLANS FOR GROWTH.

     There  can be no  assurance  that  the  Company  will  generate  sufficient
revenues to fund its future operations and growth  strategies.  At this time the
Company does not believe  product sales will reach the level required to sustain
its  operations  and  growth  plans  beyond  the near  term.  We do not have any
commitments from others to provide additional  financing in the future and there
can be no  assurance  that any such  additional  financing  will be available if
needed or, if  available,  will be on terms  favorable  to us. In the event such
needed  financing is not obtained,  our operations will be materially  adversely
affected  and we will  have to cease or  substantially  reduce  operations.  Any
additional   equity  financing  may  be  dilutive  to  stockholders,   and  debt
financings, if available, may involve restrictive covenants.

                                       6

WE MAY HAVE DIFFICULTIES IN MANAGING GROWTH.

     We  will  need  to  grow  our  product  sales  and   manufacturing   output
significantly  in order to be  successful.  If we are  unable to  manage  growth
effectively,   it  could  have  material  adverse  effects  on  our  results  of
operations,  financial condition or liquidity.  We cannot guarantee that we will
successfully  expand or that any expansion  will enhance our  profitability.  We
expect our planned growth will place a significant  strain on our management and
operations. Our future growth will depend in part on the ability of our officers
and other key employees to implement and expand financial control systems and to
expand,  train and manage our employee  base and provide  support to an expanded
customer base.

WE MAY HAVE ADVERSE IMPACT FROM ACQUISTIONS.

     Our  strategy   includes  the  potential   acquisition   of   complimentary
businesses, and integration of additional products,  technologies and personnel.
We have limited  experience  in acquiring  outside  businesses.  Acquisition  of
businesses requires  substantial time and attention of management  personnel and
may require additional equity or debt financing.  There can be no assurance that
we will be successful in  identifying,  consummating  or  integrating  strategic
acquisitions.

     Integration of newly  established  or acquired  business can be disruptive.
There can be no assurance  that we will be able to integrate such companies into
our  business  successfully.  Financial  consequences  of our  acquisitions  may
include  potentially  dilutive  issuances of equity  securities;  large one-time
expenses;  higher  fixed  expenses  which  require a higher level of revenues to
maintain gross margins; the incurrence of debt and contingent  liabilities;  and
amortization expenses related to goodwill and other intangible assets.

OUR PRODUCTS  ARE AT AN EARLY STAGE OF  DEVELOPMENT  AND MAY NOT ACHIEVE  MARKET
ACCEPTANCE.

     Through  June  1996,  our  primary   activities  were  basic  research  and
development of glass material  properties.  Our current line of GRADIUM products
have  not  generated   sufficient   revenues  to  sustain   operations  and  our
telecommunications  products  are  still  in the  introductory  phase.  While we
believe our existing products are commercially viable, we anticipate the need to
educate the optical  components  market in order to generate  market  demand and
market feedback may require us to further refine these products.  Development of
additional product lines will require significant further research, development,
testing and marketing prior to commercialization. There can be no assurance that
any proposed  products will be  successfully  developed,  demonstrate  desirable
optical  performance,  be capable of being produced in commercial  quantities at
reasonable costs or be successfully marketed.

OUR PRODUCTS HAVE NOT BEEN DEMONSTRATED TO BE COMMERCIALLY SUCCESSFUL.

     Our  telecommunication  products  have not yet  achieved  broad  commercial
acceptance.  The traditional  optics have been accepted  commercially;  however,
their benefits are not widely known. Although we are engaged in negotiations and

                                       7

discussions  with potential  customers,  there can be no assurance that any such
discussions  will  lead  to  development  of  commercially  viable  products  or
significant  revenues,  if any, or that any products currently existing or to be
developed in the future will attain  sufficient  market  acceptance  to generate
significant  revenues.  In order to  persuade  potential  customers  to purchase
GRADIUM products, we will need to overcome industry resistance to, and suspicion
of,  gradient lens technology that has resulted from previous failed attempts by
various  researchers and manufacturers  unrelated to us to develop a repeatable,
consistent  process for producing lenses with variable  refractive  indices.  We
must  also  satisfy  industry-standard  Bellcore  Testing  on  telecommunication
products to meet customer requirements, as well as satisfy prospective customers
that we will be able to meet their demand for  quantities of products,  since we
may be the sole supplier and licensor. We do not have demonstrated experience as
a  manufacturer  and have  limited  financial  resources.  We may be  unable  to
accomplish  any one or more of the foregoing to the extent  necessary to develop
market  acceptance  of our  products.  Prospective  customers  will need to make
substantial  expenditures  to redesign  products to incorporate  GRADIUM lenses.
There can be no assurances  that  potential  customers will view the benefits of
our products as sufficient to warrant such design expenditures.

WE DEPEND UPON KEY PERSONNEL.

     Our  inability  to retain or attract  key  employees  could have a material
adverse effect on our business and results of operations. Our operations depend,
to a great extent, upon the efforts of our CEO and President, Donald Lawson, who
conceived our strategic plan and who is  substantially  responsible for planning
and guiding our direction,  and upon Mark Fitch,  our Senior Vice President.  We
also depend upon our ability to attract additional members to our management and
operations teams to support our expansion strategy. The loss of any of these key
employees would adversely  affect our business.  We have obtained a key employee
life insurance policy in the amount $1,000,000 on the life of Mr. Lawson. We had
sixty employees on March 31, 2000. Additional personnel will need to be hired if
we are able to  successfully  expand our  operations.  There can be no assurance
that we will be able to identify,  attract and retain  employees with skills and
experience necessary and relevant to the future operations of our business.

COMPETITION MAY ADVERSELY AFFECT OUR OPERATIONS AND FINANCIAL RESULTS.

     The optical lens and  telecommunication  components  markets are  intensely
competitive and numerous  companies  offer products and services  competitive to
those  offered  by us.  Substantially  all of  these  competitors  have  greater
financial  and other  resources  than we do. We compete  with  manufacturers  of
conventional spherical lens products and aspherical lens products,  producers of
optical  quality  glass and other  developers of gradient  lens  technology  and
telecom   product   manufacturers.   In  the   both   the   optical   lens   and
telecommunications  componets markets,  we are competing against,  among others,
established  international  industry  giants.  Many of these  companies also are
primary customers for optical and  telecommunication  components,  and therefore
have  significant  control over certain  markets for our  products.  We are also
aware of other  companies that are  attempting to develop  radial  gradient lens
technology.  There  may  also be  others  of  which  we are not  aware  that are

                                       8

attempting to develop axial gradient lens technology  similar to our technology.
There can be no  assurance  that  existing or new  competitors  will not develop
technologies  that are  superior  to or more  commercially  acceptable  than our
existing and planned technologies and products.

WE HAVE  LIMITED  MARKETING  AND SALES  CAPABILITIES  AND MUST  MAKE  SALES IN A
FRAGMENTED MARKET.

     Our  operating  results  will  depend to a large  extent on our  ability to
educate  the  various  industries  utilizing  telecommunication  components  and
optical  glass about the  advantages  of our products to market  products to the
participants  within those industries.  We currently have very limited marketing
capabilities  and  experience  and have  recently  hired  additional  sales  and
marketing  personnel  to develop  additional  sales and  marketing  programs and
establish sales distribution channels in order to achieve and sustain commercial
sales of our products. Although we have developed a marketing plan, there can be
no assurance that the plan will be implemented or, if implemented,  will succeed
in creating  sufficient levels of customer demand for our products.  The markets
for  optical  lenses and  telecommunication  components  are highly  fragmented.
Consequently, we will need to identify and successfully target particular market
segments in which we believe we will have the most  success.  These efforts will
require a substantial, but unknown, amount of effort and resources.

     The fragmented nature of the optical products market may impede our ability
to achieve commercial acceptance for our products. In addition, our success will
depend in great part on our  ability  to  develop  and  implement  a  successful
marketing and sales  program.  There can be no assurance  that any marketing and
sales  efforts  undertaken  by us  will be  successful  or  will  result  in any
significant product sales.

WE ARE HIGHLY DEPENDENT ON OUR PATENTS AND PROPRIETARY TECHNOLOGY.

     Our success will depend,  in part, on our ability to obtain  protection for
products and  technologies  under  United  States and foreign  patent  laws,  to
preserve trade secrets, and to operate without infringing the proprietary rights
of others.  There can be no assurance that patent  applications  relating to our
products or potential  products will result in patents  being  issued,  that any
issued   patents  will  afford   adequate   protection  or  not  be  challenged,
invalidated,  infringed or circumvented,  or that any rights granted will afford
competitive advantages to us. Furthermore, there can be no assurance that others
have not independently  developed,  or will not independently  develop,  similar
products and/or technologies,  duplicate any of our product or technologies, or,
if patents are issued to, or licensed by, us, design around such patents.  There
can  be  no  assurance  that  patents  owned  or  licensed  and  issued  in  one
jurisdiction will also issue in any other jurisdiction.  Furthermore,  there can
be no assurance  that we can  adequately  preserve  proprietary  technology  and
processes  that we  maintain as trade  secrets.  If we are unable to develop and
adequately  protect our proprietary  technology and other assets,  our business,
financial  condition  and results of  operations  will be  materially  adversely
affected.

                                       9

OUR BUSINESS DEPENDS UPON THE EFFORTS OF THIRD PARTIES.

     Our strategy for the research, development and commercialization of certain
products entails  entering into various  arrangements  with corporate  partners,
OEMs,  licensees and others in order to generate  product  sales,  license fees,
royalties and other funds adequate for product development.  We may also rely on
our collaborative  partners to conduct research efforts,  product testing and to
manufacture and market certain of our products. Although we believe that parties
to any such  arrangements  would  have an  economic  motivation  to  succeed  in
performing  their  contractual  responsibilities,   the  amount  and  timing  of
resources to be devoted to these activities may not be within our control. There
can also be no assurance  that we will be  successful in  establishing  any such
collaborative  arrangements  or  that,  if  established,  the  parties  to  such
arrangements  will assist us in  commercializing  products.  We  currently  have
development  agreements with a mechanical  switch  manufacturer and an endoscope
manufacturer  pursuant to which we have developed prototypes of products for use
in each of those areas. However,  there can be no assurance that such agreements
will progress to a production  phase or, if production  commences,  that we will
receive significant revenues from these  relationships.  We have a non-exclusive
agreement with a catalog company to distribute certain of its products.  We have
formalized  relationships with eight foreign  distributors to create markets for
GRADIUM in their  respective  countries.  There can be no  assurance  that these
parties,  or any future partners,  will perform their obligations as expected or
that any revenue will be derived from such arrangements.

WE HAVE ONLY LIMITED MANUFACTURING CAPABILITIES.

     We believe that our present manufacturing  facilities,  with the clean room
addition  which was completed in October 1999,  are  sufficient  for our planned
operations in fiscal 2000. We have acquired  additional  manufacturing  space in
January 2000 to allow for expansion of our manufacturing capabilities.  However,
we do not have  substantial  experience  manufacturing  products  in  quantities
sufficient to meet commercial  demand. If we are unable to manufacture  products
in sufficient  quantities  and in a timely manner to meet customer  demand,  our
business,  financial  condition  and results of  operations  will be  materially
adversely affected.

WE FACE PRODUCT LIABILITY RISKS.

     The sale of our optical  products will involve the inherent risk of product
liability  claims by others.  We do not  currently  maintain  product  liability
insurance  coverage,  although  we do intend to procure  such  insurance  in the
future.  Product liability  insurance is expensive,  subject to various coverage
exclusions and may not be obtainable on terms  acceptable to us.  Moreover,  the
amount and scope of any  coverage may be  inadequate  to protect us in the event
that a product liability claim is successfully asserted.

WE WILL RECOGNIZE A SUBSTANTIAL  CHARGE TO INCOME UPON CONVERSION OF OUR CLASS E
COMMON STOCK.

     In the event any shares of the Class E Common  Stock  held by  stockholders
who are  officers,  directors,  employees or  consultants  of the Company  reach
targets to enable conversion into shares of Class A Common Stock, we will record

                                       10

compensation expense for financial reporting purposes during the period in which
the targets are reached and  conversion  appears  probable.  These  targets will
expire in  September  2000 based on the  operating  results as of June 30, 2000.
Such  charge  will  equal the fair  market  value of such  shares on the date of
release,  which may be substantial.  Although the amount of compensation expense
recognized  will  not  affect  the  total  stockholders'  equity,  it may have a
material negative effect on the market price of our securities, particularly the
shares of Class A Common  Stock.  Additionally,  since  shares of Class E common
stock  are not  treated  as  outstanding  for  purposes  of  earnings  per share
calculations,  the increase in the number of shares of Class A Common Stock upon
conversion  of any series of Class E Common  Stock may have a  material  adverse
effect on our earnings per share.

OUR STOCK PRICE IS VOLATILE.

     Broad market  fluctuations  or fluctuations in our operations may adversely
affect the market price of our common stock.  The market for our common stock is
volatile. The trading price of our common stock has been and will continue to be
subject to:

     +    volatility  in the trading  markets  generally  and in our  particular
          market segment;
     +    significant  fluctuations  in  response  to  quarterly  variations  in
          operating results;
     +    announcements   regarding   our   business  or  the  business  of  our
          competitors;
     +    changes in prices of our or our competitors' products and services;
     +    changes in product mix; and
     +    changes in revenue and revenue  growth  rates for us as a whole or for
          geographic areas, and other events or factors.

     Statements or changes in opinions,  ratings or earnings  estimates  made by
brokerage firms or industry analysts relating to the markets in which we operate
or expect to operate  could have an  adverse  effect on the market  price of our
common  stock.  In  addition,  the  stock  market  as a  whole,  as  well as our
particular market segment,  have from time to time experienced extreme price and
volume  fluctuations  which have particularly  affected the market price for the
securities  of many  companies  and  which  often  have  been  unrelated  to the
operating performance of these companies.

POTENTIAL CONTROL BY THE EXISTING MANAGEMENT AND SHAREHOLDERS.

     If our management and shareholders  act in concert,  disposition of matters
submitted to  shareholders  or the election of the entire Board of Directors may
be hindered.  We estimate that the  principal  stockholders  beneficially  owned
26.5% of the total combined voting power of all of the Common Stock  outstanding
at April 14, 2000.

                                       11

SOME  PROVISIONS  IN OUR  CHARTER  DOCUMENTS  AND BYLAWS MAY HAVE  ANTI-TAKEOVER
EFFECTS.

     Our  Certificate of  Incorporation  and Bylaws contain some provisions that
could have the effect of  discouraging  a  prospective  acquirer  from  making a
tender  offer,  or which  may  otherwise  delay,  defer or  prevent  a change in
control.

ABSENCE OF DIVIDENDS TO SHAREHOLDERS.

     Our Board has never  declared a dividend  on our  common  stock.  We do not
anticipate paying dividends on the common stock in the foreseeable future. It is
anticipated  that  earnings,  if any, will be reinvested in the expansion of our
business.

OUR  CONVERTIBLE  PREFERRED  STOCK,  WARRANTS  AND OPTIONS MAY AFFECT OUR FUTURE
FINANCING.

     The existence of our outstanding  Convertible  Preferred Stock,  options or
warrants  may  adversely  affect  the  terms on which we can  obtain  additional
financing. As of March 31, 2000, there was outstanding:

     +    2,768,458  Class B Warrants to purchase  2,768,458,  shares of Class A
          Common Stock;

     +    the Unit Purchase  Option to purchase an aggregate of 29,670 shares of
          Class A Common Stock and 29,670 Class B Warrants;

     +    58,297 shares of Class A Common Stock  issuable upon exercise  private
          placement warrants;

     +    328,875  shares of Class A Common  Stock  reserved for issuance to the
          selling  shareholders  upon  conversion  of the 153  remaining  shares
          Series F Preferred stock;

     +    281,250  shares of Class A Common Stock  issuable  upon  exercise of a
          warrant held by Robert Ripp, our Chairman of the Board;

     +    outstanding  options to purchase an aggregate  of 1,189,204  shares of
          Class A Common Stock (which includes 61,211 options  pursuant to which
          the holders  would  receive,  upon  exercise,  an  aggregate of 61,211
          shares of Class A, 91,817 shares of Class E-1,  91,187 shares of Class
          E-2 and 61,211 shares of Class E-3 Common Stock);

     +    approximately  613,000  shares of Class A Common  Stock  reserved  for
          issuance  pursuant  to  future  grants to be made  under  the  Omnibus
          Incentive Plan and Directors Stock Incentive Plan;

                                       12

     +    in  addition,  1,207,158  shares of Class A Common Stock issued to the
          shareholders  of HPI and 250,721  stock  options to acquire  shares of
          Class A common  stock  granted to employees of HPI as of the April 14,
          2000 closing;

     +    in addition,  1,500,000  nonqualified stock options to purchase shares
          of Class A Common  Stock  granted to the  Chairman of the Board of the
          Company on April 12, 2000.

     For the life of such options, warrants and Convertible Preferred Stock, the
holders  will have the  opportunity  to  profit  from a rise in the price of the
underlying  common  stock,  with a resulting  dilution in the  interest of other
holders of common stock upon  exercise or  conversion.  Further,  the option and
warrant holders can be expected to exercise their options and warrants at a time
when we would, in all  likelihood,  be able to obtain  additional  capital by an
offering of our unissued  common stock on terms more  favorable to us than those
provided by such options or warrants.

     The eligibility of the foregoing  shares to be sold to the public,  whether
pursuant an effective registration statement,  Rule 144 or an exemption from the
registration requirements may have a material adverse effect on the market value
and trading price of the Class A Common Stock.

WE HAVE AGREED TO CERTAIN LIMITATIONS UPON POTENTIAL LIABILITY OF OUR DIRECTORS.

     Our  Certificate  of  Incorporation  provides  that  directors  will not be
personally  liable for monetary  damages to LightPath or its  stockholders for a
breach of fiduciary duty as a director, subject to limited exceptions.  Although
such  limitation  of  liability  does not affect the  availability  of equitable
remedies  such as  injunctive  relief  or  rescission,  the  presence  of  these
provisions in the  Certificate  of  Incorporation  could prevent the recovery of
monetary damages by LightPath or its stockholders.

WE MUST MAINTAIN  COMPLIANCE WITH CERTAIN  CRITERIA IN ORDER TO MAINTAIN LISTING
OF OUR SHARES ON THE NASDAQ MARKET.

     The Class A Common Stock and Class B Warrants are  currently  traded on the
Nasdaq  SmallCap  Market.  Failure to meet the  applicable  quantitative  and/or
qualitative  maintenance  requirements  of Nasdaq could result in our securities
being  delisted from Nasdaq,  with the result that such  securities may trade on
the OTC  Bulletin  Board or in the  "pink  sheets"  maintained  by the  National
Quotation Bureau Incorporated.  As a consequence of such delisting,  an investor
could find it more difficult to dispose of or to obtain  accurate  quotations as
to the market value of our securities. Among other consequences,  delisting from
Nasdaq may cause a decline in the stock price and difficulty in obtaining future
financing.

                                       13

WE MAY NOT HAVE ENOUGH FUNDS AVAILABLE TO REDEEM OUTSTANDING SHARES OF PREFERRED
STOCK.

     In the event of automatic conversion of the Series F Preferred Stock, three
years after issuance  LightPath has the right to redeem such preferred stock for
cash. In addition, a Liquidation Event, as defined in the applicable Certificate
of Designation, may require redemption of the Series F Preferred Stock for cash.
There can be no assurance  that we will have  adequate  cash to effect such cash
redemptions in the future.

RISK THAT FORWARD-LOOKING STATEMENTS MAY NOT COME TRUE.

     This prospectus and the documents incorporated herein by reference, contain
forward-looking  statements that involve risks and  uncertainties.  We use words
such as "believe",  "expect,"  "anticipate," "plan" or similar words to identify
forward-looking  statements.  Forward-looking statements are made based upon our
belief as of the date  that such  statements  are  made.  These  forward-looking
statements  are based largely on our current  expectations  and are subject to a

SECURITY OWNERSHIP OF PRINCIPAL STOCKHOLDERS AND MANAGEMENT

     The Proxy  Statement  for the 1999  Annual  Meeting  contained  information
concerning  the  number of shares  included  in the  Voting  Trust  that  Leslie
Danziger,  former Chairwoman of the Board of Directors, was entitled to vote. As
of September 16, 1999,  Ms.  Danziger was no longer the  Chairwoman of the Board
and as a result  the  Voting  Trust  has  dissolved  by its  terms.  All  shares
previously subject to the Voting Trust are now held directly by their beneficial
owners, each of whom (to LightPath's knowledge)  independently votes and has the
power to dispose of such shares.

                              SELLING SHAREHOLDERS

     On April 14, 2000,  we issued  1,207,158  shares of Class A Common Stock in
connection with our acquisition of Horizon  Photonics,  Inc. (HPI) pursuant to a
Merger  Agreement of the same date. The number of shares of Class A Common Stock
issued to the former HPI  shareholders  is  subject to post  closing  adjustment
based on the trading price of our Class A Common Stock during the period between
the  acquisition  closing date and the earlier to occur of the date such Class A
Common Stock is registered or May 29, 2000. The range of the aggregate number of
shares  that could be issued is a minimum  of 603,579 to a maximum of  2,011,934
shares of Class A Common Stock.  This  Prospectus  covers the maximum  number of
shares  of Class A Common  Stock  that  could be  issued  under the terms of the
Merger Agreement.

     The following table provides information as of April 17, 2000, with respect
to the Class A Common Stock beneficially owned by each selling shareholder.  For
purposes  of the  information  set  forth in this  table,  the  number of shares
beneficially  owned includes  shares issuable upon the exercise of stock options
that are vested on April 17, 2000 or within sixty days thereafter.

                                 USE OF PROCEEDS

     Each of the selling  shareholders  will receive the net  proceeds  from the
sale of its shares of common stock.  We will not receive any proceeds from these
sales.

                         DETERMINATION OF OFFERING PRICE

     The selling  shareholders may use this prospectus from time to time to sell
their shares of common stock at a price  determined  by the  shareholder  making
such sale.  The price at which the  common  stock is sold may be based on market
prices  prevailing  at the time of sale, at prices  relating to such  prevailing
market prices, or at negotiated prices.

                              PLAN OF DISTRIBUTION

     The common stock may be sold from time to time by the selling shareholders,
or by pledgees,  donees, transferees or other successors in interest. Such sales
may be  made on one or  more  exchanges  or in the  over-the-counter  market  or
otherwise,  at prices and at terms then  prevailing or at prices  related to the
then current market price, or in negotiated  transactions.  The common stock may
be sold in one or more of the following types of transactions:

          (a) a block  trade  in  which a  selling  shareholder  will  engage  a
broker-dealer  who will then attempt to sell the common  stock,  or position and
resell a portion of the block as principal to facilitate the transaction;

          (b)  purchases  by a  broker-dealer  as  principal  and resale by such
broker-dealer for its account pursuant to this prospectus;

          (c) an  exchange  distribution  in  accordance  with the rules of such
exchange; and

          (d) ordinary  brokerage  transactions  and  transactions  in which the
broker solicits purchasers.  In effecting sales,  broker-dealers  engaged by the
selling  shareholders may arrange for other broker-dealers to participate in the
resales.

     In connection  with  distributions  of the common stock or  otherwise,  the
selling shareholders may enter into hedging transactions with broker-dealers. In
connection with such  transactions,  broker-dealers may engage in short sales of
the common stock in the course of hedging the positions they assume with selling
shareholders.  The selling  shareholders  may also sell  common  stock short and
redeliver  the  common  stock to close out such  short  positions.  The  selling
shareholders   may  also  enter   into   option  or  other   transactions   with
broker-dealers  that  require the  delivery to the  broker-dealer  of the common
stock, which the broker-dealer may resell or otherwise transfer pursuant to this
prospectus.  The selling  shareholders may also loan or pledge common stock to a
broker-dealer and the broker-dealer may sell the common stock so loaned or, upon
a default,  the  broker-dealer  may effect  sales of the  pledged  common  stock
pursuant to this prospectus.

                                       16

     Broker-dealers   or  agents  may  receive   compensation  in  the  form  of
commissions,  discounts or concessions from the selling  shareholders in amounts
to be negotiated in connection with the sale. Such  broker-dealers and any other
participating  broker-dealers  may be deemed  to be  "underwriters"  within  the
meaning  of the  Securities  Act in  connection  with  such  sales  and any such
commission, discount or concession may be deemed to be underwriting discounts or
commissions  under the Securities  Act. In addition,  any securities  covered by
this  prospectus  which  qualify for sale pursuant to Rule 144 may be sold in an
unregistered transaction under Rule 144 rather than pursuant to this prospectus.

     We will  bear all of the  costs  and  expenses  of  registering  under  the
Securities  Act the  sale  of the  common  stock  offered  by  this  prospectus.
Commissions and discounts, if any, attributable to the sales of the common stock
will be borne by the selling shareholders.

     We have  agreed to  indemnify  the  selling  shareholders  against  certain
liabilities  in  connection  with the  offering of the common  stock,  including
liabilities arising under the Securities Act. The selling shareholders may agree
to  indemnify  any  broker-dealer  or agent that  participates  in  transactions
involving  sales of the common  stock  against  various  liabilities,  including
liabilities arising under the Securities Act.

     In  order  to  comply  with  the  securities  laws of  various  states,  if
applicable,  sales of the common  stock made in those  states  will only be made
through registered or licensed brokers or dealers.  In addition,  some states do
not  allow the  securities  to be sold  unless  they  have  been  registered  or
qualified for sale in the applicable state or an exemption from the registration
or  qualification  requirement  is available  and is complied with by us and the
selling shareholders.

     Under  applicable  rules and  regulations  of the Exchange  Act, any person
engaged in the distribution of the common stock may not simultaneously engage in
market-making  activities with respect to our common stock for a period of up to
five business days prior to the commencement of such  distribution.  In addition
to those restrictions,  each selling shareholder will be subject to the Exchange
Act and the rules and regulations under the Exchange Act, including,  Regulation
M and Rule 10b-7,  which  provisions  may limit the timing of the  purchases and
sales of our securities by the selling shareholders.

                            DESCRIPTION OF SECURITIES

     We have  previously  registered our Class A Common Stock under the Exchange
Act by filing a Form 8-A on January 13, 1996.  Please refer to that registration
statement for a description  of the rights,  privileges  and  preferences of our
common stock.

     The report of KPMG LLP  covering the June 30,  1999,  financial  statements
contains an  explanatory  paragraph  that states  that the  Company's  recurring
losses from operations and resulting continued dependence on external sources of
capital raise  substantial  doubt about the  Company's  ability to continue as a
going  concern.  The financial  statements do not include any  adjustments  that
might result from the outcome of that uncertainty.

     HPI's financial statements as of March 31, 2000 and 1999, and for the years
then ended,  have been  incorporated by reference  herein,  in reliance upon the
report  of  Windes  &  McClaughry,  Accountancy  Corporation,   incorporated  by
reference  herein,  and upon the authority of said firm as experts in accounting

                     INTERESTS OF NAMED EXPERTS AND COUNSEL

     On October  13,  1997,  James L.  Adler,  Jr. was  appointed  to serve as a
director of LightPath until the 2000 annual meeting of  shareholders.  Mr. Adler
is a partner  of the law firm of  Squire,  Sanders & Dempsey  L.L.P.,  which has
issued an opinion as to the  validity of the shares  offered by this  prospectus
and also  provides  legal  services to us on a regular  basis.  Mr.  Adler holds
options under the Directors Stock Option Plan to purchase 40,176 shares of Class
A Common Stock at exercise  prices ranging from $2.84 to $9.81.  As of April 17,
2000, these shares  represented less than 1% of the total outstanding  shares of
Class A Common Stock.

                                 INDEMNIFICATION

     Article TENTH of the Company's  Certificate of  Incorporation,  as amended,
provides as follows:

     TENTH:  No director of the  corporation  shall be personally  liable to the
corporation  or its  stockholders  for monetary  damages for breach of fiduciary
duty as a director; provided, however, that the foregoing clause shall not apply
to any  liability  of a director  (i) for any breach of the  director's  duty of
loyalty to the corporation or its  stockholders,  (ii) for acts or omissions not
in good faith or which involve intentional  misconduct or a knowing violation of
law,  (iii) for any  transaction  from which the  director  derived an  improper
personal benefit,  or (iv) under Section 174 of the DGCL. This Article shall not
eliminate or limit the liability of a director for any act or omission occurring
prior to the time this Article became effective.

     Article VII of the Company's Bylaws provides,  in summary, that the Company
is required to indemnify to the fullest extent  permitted by applicable law, any
person made or threatened to be made a party or involved in a lawsuit, action or
proceeding by reason that such person is or was an officer,  director,  employee

                                       18

or agent of the  Company.  Indemnification  is against  all  liability  and loss
suffered  and  expenses  reasonably  incurred.  Unless  required by law, no such
indemnification  is required by the Company of any person  initiating such suit,
action or  proceeding  without  board  authorization.  Expenses  are  payable in
advance if the indemnified  party agrees to repay the amount if he is ultimately
found to not be  entitled to  indemnification.  For a full text of Article VI of
the Bylaws, see Exhibit 3.3 to this Registration Statement.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933,  the  Securities  Act,  may be  permitted  to  directors,  officers and
controlling  person  of  LightPath  pursuant  to the  foregoing  provisions,  or
otherwise,  we have been  informed  that in the  opinion of the  Securities  and
Exchange  Commission such  indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable.

ITEM 17. UNDERTAKINGS

     The undersigned Registrant hereby undertakes that:

     (1) It will file a post-effective amendment to remove from registration any
of the securities that remain unsold at the end of the offering.

     (2) For purposes of determining  any liability under the Securities Act, it
will  treat  each  post-effective  amendment  as 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) It will  file,  during  any  period in which  offers or sales are being
made, a post-effective  amendment to this Registration  Statement to include any
additional or changed material information on the plan of distribution.

     (4) Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant pursuant to the provisions described in Item 15 hereof, 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  Securities  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  thereof 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  whether  such
indemnification  by it is against  public policy as expressed in the  Securities
Act and will be governed by the final adjudication of such issue.

certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-3 and has  duly  caused  this  Registration
Statement  to be  signed  on its  behalf  by the  undersigned,  there  unto duly
authorized, in the City of Albuquerque, State of New Mexico, on May 19, 2000.
