INFORMATION  INCLUDED AT OTHER  SECTIONS OF THIS  PROSPECTUS.  IN ADDITION,  YOU

OF THIS PROSPECTUS.

                          LIGHTPATH TECHNOLOGIES, INC.

     LightPath  Technologies,  Inc.  is a  Delaware  corporation  that  produces
GRADIUM(R)  glass,  utilizes  otheR optical  materials and  specialized  optical
packaging concepts to manipulate light and performs research and development for
optical  solutions  in  the  fiber  telecommunications  and  traditional  optics
markets.  Our fiscal year ends on June 30 and references to fiscal years are for
the applicable years ended June 30.

     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.  LightPath has been issued seventeen 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  technology.  We are  continually  developing new GRADIUM
glass materials with various  refractive  index and dispersion  profiles and for
the telecommunications field; 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 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   separate   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
<PAGE>
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 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 major OEM manufacturer 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. Rodenstock's one hundred years of experience in
the field of advanced optical systems and employees over 6,000 people worldwide,
will be a strong asset to the expansion of  LightPath's  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,  we, through our printed and Internet on-line catalog, offer
a  standard  line of  GRADIUM  glass  lenses  for  commercial  sales to  optical
designers  developing  particular systems for original  equipment  manufacturers
("OEMs") or in-house products.

     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  stage  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

                                       2
<PAGE>
to the traditional  optics market continued with significant  increases in sales
of lenses used in the YAG laser market, catalog and distributor sales and 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 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.  With the resolution of
packaging  and  alignment  issues by us,  and  advances  made by  LightChip,  an
affiliate,  with WDM  equipment,  it 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  straighten  and  make  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 generate  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  its existing
flint products,  and further  development of acrylic axial gradient  material to
extend the range of existing product applications.

                                  RISK FACTORS

         BEFORE YOU BUY ANY OF THE SHARES OF COMMON STOCK BEING  OFFERED BY THIS
PROSPECTUS,  YOU SHOULD  CAREFULLY READ AND CONSIDER EACH OF THE RISK FACTORS WE
HAVE  DESCRIBED IN THIS  SECTION.  YOU SHOULD BE PREPARED TO ACCEPT ALL OF THESE
RISKS,  INCLUDING THE RISK THAT YOU MAY LOSE YOUR ENTIRE INVESTMENT,  BEFORE YOU
MAKE A DECISION TO BUY ANY OF THE SHARES OF COMMON STOCK.

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, our operations will ever be profitable.

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

         We have 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.

         We  anticipate  that our  projected  product sales and the net proceeds
from our private  placement  of  convertible  debentures  and related  warrants,
completed in July 1999,  will be used for working  capital for fiscal  2000.  In
addition,  our  ability to fund  capital  requirements  after the near term will
depend on the extent that our products become commercially  accepted, if at all,
and if our marketing  program is successful  in generating  sales  sufficient to
sustain our operations.  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; therefore, the Company is actively pursuing additional financing.
We do not have any commitments from others to provide such additional  financing
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.

                                       5

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  a  material  adverse  effect  on our  results  of
operations,  financial  condition or business.  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.

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  the
telecommunications  products  are  still  in the  introduction  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  commercial
acceptance  while the traditional  optics are not widely known.  Although we are
engaged in negotiations and 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 do not have a substantial
net worth.  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 product's benefits as sufficient to warrant such design expenditures.

                                       6
<PAGE>
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 key employee
life insurance  policies in the amount  $1,000,000 on the life of Mr. Lawson. We
had twenty-five  employees on August 1, 1999.  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  products.  In the markets for conventional and aspheric lenses,  we are
competing against, among others, established international industry giants. Many
of these  companies  also are  primary  customers  for optical  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
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 technology 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 optical glass about the advantages of
GRADIUM and other  optical  materials  to market  products  to the  participants
within those industries.  We currently have very limited marketing  capabilities
and experience and will need to hire additional  sales and marketing  personnel,
develop additional sales and marketing programs and establish sales distribution
channels  in order to achieve  and  sustain  commercial  sales of its  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.

                                       7
<PAGE>
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.

OUR BUSINESS DEPENDS UPON THE EFFORTS OF THIRD PARTIES.

         Our strategy for the research,  development  and  commercialization  of
certain  of  its  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 its  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.
Presently we have entered into a development  agreement with a mechanical switch
manufacturer  and an endoscope  manufacturer  pursuant to which it has developed
prototypes.  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  this  relationship.  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 expected to be completed by the end of the calendar year 1999, are
sufficient for our planned operations over the next several years.  However,  we
do not have any 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.

                                       8
<PAGE>
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  are  converted  into  shares of Class A Common  Stock,  we will  record
compensation expense for financial reporting purposes during the period in which
such  conversion  occurs.  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.  Since Class E shares 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 OPERATIONS MAY BE ADVERSELY AFFECTED BY PROBLEMS ASSOCIATED WITH THE YEAR
2000 ISSUE.

         Some  computer  applications  were  originally  designed  to  recognize
calendar  years by their last two digits.  As a result,  calculations  performed
using these  truncated  fields will not work  properly  with dates from the year
2000 and beyond.  This problem is commonly referred to as the "Year 2000 Issue".
We have determined that our internal computer systems,  manufacturing  equipment
and software  products were  produced to be Year 2000  compliant and no material
remediation  costs have been  incurred  or are  expected  to be  incurred by us.
During the third  quarter of fiscal 1999,  we  confirmed in writing  whether the
internal  business  operations  of third  parties  with whom we have a  material
relationship  will be affected by the Year 2000 Issue.  Our  assessment of third
parties is complete and based on their responses, we believes our material third
party  relationships  will not be  adversely  impacted  by the Year  2000  Issue
barring  any  unforeseen  circumstances.  Under a  worst  case  scenario  we may
experience  delays in receiving  products and services thereby impacting product
shipments. We plans on having adequate inventory levels to minimize such impact,
if any. We will continue to monitor third  parties  throughout  the remainder of
calendar  1999 and develop  contingency  plans if a third party is  subsequently
found to be non-compliant.

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:

     *    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, rating 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 has from time to time
experienced  extreme  price and  volume  fluctuations  which  have  particularly
affected the market price for the  securities  of many small cap  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. The principal stockholders  beneficially owned 12% of
the total combined voting power of all of the Common Stock outstanding at August
19, 1999. In addition,  certain  stockholders  holding  approximately 12% of the
total  voting  power have  entered  into a voting  trust  agreement.  Additional
stockholders  may  subsequently  join the voting  trust.  Pursuant to the voting
trust, Leslie A. Danziger, the Chairwoman,  is granted the authority to vote all
of the shares  subject to the voting trust on all matters that our  stockholders
are entitled to vote. Accordingly, Ms. Danziger will likely be able to influence
the election of our  directors  and thereby  direct the policies of the Company.
These  arrangements could make it difficult for others to elect the entire Board
of Directors and to control the disposition of any matter submitted to a vote of
stockholders.

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

         Our Articles 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

         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.

                                       10
<PAGE>
OUR WARRANTS AND OPTIONS MAY AFFECT OUR FUTURE FINANCING

         The existence of our options or warrants may adversely affect the terms
on which we can obtain  additional  financing.  As of June 30,  1999,  there was
outstanding

     *    2,667,749  Class A Warrants  to  purchase an  aggregate  of  2,667,749
          shares of Class A Common Stock and 2,667,749 Class B Warrants;

     *    1,851,251  Class B Warrants  to purchase  1,851,251  shares of Class A
          Common Stock;

     *    the Unit  Purchase  Option to purchase an aggregate of 160,000  Units,
          each Unit consists of 160,000  Class A Common  Stock,  160,000 Class A
          Warrants to purchase an aggregate of 160,000  shares of Class A Common
          Stock and 160,000 Class B Warrants; and 160,000 Class B Warrants;

     *    564,821  shares of Class A Common Stock  issuable  upon  conversion of
          Series A Preferred Stock and exercise of Class C and Class D Warrants;

     *    373,914 shares of Class A Common Stock issuable upon conversion Series
          B Preferred Stock and exercise of Class E and Class F Warrants;

     *    1,130,601shares  of  Class A Common  Stock  issuable  upon  conversion
          Series C Preferred Stock and exercise of Class G and Class H Warrants;

     *    Outstanding  options to purchase an aggregate  of 1,244,851  shares of
          Class A Common Stock which includes 71,102 whereby the holder receives
          71,102 shares of Class A, 106,652 Class E-1,  106,652  shares of Class
          E-2 and 71,102 shares of Class E-3 Common Stock;

     *    970,077 shares of Class A Common Stock reserved for issuance under the
          Omnibus Incentive Plan and Directors Stock Incentive Plan.

         For the life of such  options and  warrants,  the holders will have the
opportunity to profit from a rise in the price of common stock, with a resulting
dilution in the interest of other holders of common stock.  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.

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

                                       11

THE LIQUIDITY OF OUR STOCK COULD BE SEVERELY REDUCED IF IT BECOMES CLASSIFIED AS
PENNY STOCK.

         If our securities were delisted from Nasdaq,  they could become subject
to Rule 15g-9 under the Exchange Act,  which imposes  additional  sales practice
requirements on  broker-dealers  that sell such securities to persons other than
established customers and "accredited investors".

         The Commission has adopted  regulations which generally define a "penny
stock" to be any non-Nasdaq  equity security that has a market price (as therein
defined)  of less than  $5.00 per share or with an  exercise  price of less than
$5.00 per share, subject to certain exceptions.  For any transaction involving a
penny stock, unless exempt, the rules require substantial  additional disclosure
obligations.  The foregoing  required penny stock restrictions will not apply to
our  securities so long as they continue to be listed on Nasdaq and have certain
price and volume information  provided on a current and continuing basis or meet
certain minimum net tangible assets or average revenue criteria. There can be no
assurance  that  the our  securities  will  qualify  for  exemption  from  these
restrictions.  In any  event,  even if our  securities  were  exempt  from  such
restrictions, they would remain subject to Section 15(b)(6) of the Exchange Act,
which gives the  Commission the authority to prohibit any person that is engaged
in unlawful conduct while  participating in a distribution of a penny stock from
associating  with a broker-dealer  or participating in a distribution of a penny
stock,  if the Commission  finds that such a restriction  would be in the public
interest.

         If our  securities  were subject to the existing rules on penny stocks,
the market liquidity for our securities could be severely adversely affected.

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

         The Units,  Class A Common  Stock and Class A and Class B Warrants  are
currently  traded on 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  would  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.

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

         In the  events of  conversion  of the  Convertible  Debentures  and the
Series A, Series B or Series C Preferred Stock or exercise of their accompanying
Class C,  Class E and Class G  warrants,  respectively,  in a manner  that would
cause an undue  dilution of its Common Stock,  LightPath has the right to redeem
such  debentures,  preferred  stock  and  warrants  for  cash.  In  addition,  a
Liquidation Event, as defined in the applicable Certificates of Designation, may
require  redemption  of the Series A, Series B or Series C  Preferred  Stock for
cash.  There can be no assurance that in either of the foregoing  events that we
will have adequate cash to effect such cash redemptions.

                              SELLING SHAREHOLDERS

         On July 28,  1999,  we issued  $1,000,000  Convertible  Debentures  and
427,350  attached  Class I warrants  to the  selling  shareholders  in a private
placement.  150,000  Class J Warrants were also issued to Fahnestock & Co., Inc.
as partial compensation for their services as placement agent.

         Each Class I and Class J Warrant  entitles  the holder to purchase  one
share of Class A Common  Stock at $2.20 per share at any time through July 2004.
For a  description  of the Class I Warrants see Exhibit 4.7 to the  registration
statement.  For a  description  of the Class J Warrants  see  Exhibit 4.8 to the
registration  statement.  Each  convertible  debenture  can be  converted by the
holder into a number of shares of our Class A Common  Stock at the option of the
holder at any time until July 2002. The number of shares of Class A Common Stock
issuable upon conversion of each convertible debenture is determined by dividing
the  outstanding  principal  amount  plus 6%  accrued  interest,  on the date of
conversion by a conversion  price. The conversion price is defined as the lesser
of 80% of the average closing bid price of our Class A Common Stock for the five
days preceding (i) the closing,  $1.76 or (ii) the conversion date,  except that
the conversion price can not be lower than $.56 nor higher than $2.00.

         We have the right to redeem all or part of the  Convertible  Debentures
at any time by advance notice to the holders.  The redemption  price is equal to
115% of the outstanding  principal of the debenture plus accrued interest. If we
do not make the redemption  payment within 10 days of that notice,  however,  we
will lose this redemption right.

         Interest  at the rate of 6% per annum is  payable on the  principal  of
each Convertible Debenture on conversion or at maturity. At our option, interest
may be paid in cash or in Class A Common Stock at the  conversion  price then in
effect.

         The  terms of the  convertible  debenture  and the  Class I and Class J
Warrants specify that, with limited  exceptions,  a selling  shareholder  cannot
convert the debenture or exercise its warrant to the extent that such conversion
or exercise  would result in the selling  shareholder  and its  affiliates  then
owning more than 9.99% of the then outstanding Class A Common Stock. The limited
exceptions include the automatic  conversion of the debenture on maturity or the
existence of a tender offer for our Class A Common Stock.

         We have also  agreed  with the  debenture  holders  that under  certain
conditions if, within two years after the closing of their transaction, we issue
Class A Common Stock of  securities  convertible  into Class A Common Stock to a
third party, we will issue additional  shares to those holders.  This obligation
will  apply if the  transaction  with the third  party is  determined  to hive a
higher yield than the Convertible Debenture holder's transaction.

         This Prospectus  relates to the shares of Class A Common Stock that may
be acquired by the  selling  shareholders  upon  conversion  of the  Convertible
Debentures,  the  payment of  interest  on the  debentures  in shares of Class A
Common Stock, the additional  shares that may be issued to the debenture holders
as a result of certain  transactions we might enter into with third parties, and
the shares issuable upon exercise of the Class I and Class J Warrants.

         The following  table provides  information  as of August 1, 1999,  with
respect  to the  Class  A  Common  Stock  beneficially  owned  by  each  selling
shareholder.  For  purposes of the  information  set forth in this table,  it is
assumed that each outstanding  Convertible  Debenture was converted at $1.755 as
of  August  1,  1999.  None  of  these  selling   shareholders  has  a  material
relationship  with us, with the exception of Fahnestock & Co., Inc., which acted
as placement agent in connection with the sale of the Convertible Debentures and
warrants to the other  selling  shareholders.  As part of that sale,  we entered
into certain  agreements  with the selling  shareholders.  These  agreements are
described  under  "Certain  Relationships"  below.  We believe  that the selling
shareholders  named in the following table have sole voting and investment power
with respect to the respective shares of Class A Common Stock set forth opposite
their names.  The shares of Class A Common Stock offered by this  prospectus may
be offered  from time to time by the selling  shareholders  named below or their
nominees.

* Represents beneficial ownership of less than 1%.
(1)  Except as otherwise  noted,  and subject to community  property laws, where
     applicable,  each  person  named in the  table  has sole  voting  power and
     investment power with respect to all shares shown as beneficially owned.
(2)  As noted below,  the information set forth below includes shares of Class A
     Common  Stock  issuable  upon  conversion  of  shares  of  our  Convertible
     Debentures.  Each  Convertible  Debenture is  convertible  into a number of
     shares of Class A Common Stock  determined  by dividing its stated value on
     the date of  conversion  by a conversion  price.  The  conversion  price is
     defined as the lesser of 80% of the average  closing bid price of our Class
     A Common Stock for the five days preceding (i) the closing  ($1.76) or (ii)
     the conversion date. The conversion  price,  however,  cannot be lower than
     $.56 nor higher  than $2.00 For  purposes of the  information  set forth in
     this table, it is assumed that each outstanding  Convertible  Debenture was
     converted at $1.755 as of August 1, 1999.

     As required by SEC regulations,  the number of shares shown as beneficially
     owned includes shares which could be acquired within 60 days after the date
     of this Prospectus.  However, the provisions of the Convertible  Debentures
     and the Class I and Class J Warrants limit each holder from  converting its
     debentures or exercising its warrants to the extent that such conversion or
     exercise would result in the holder and its affiliates  beneficially owning
     more that 9.99% of the then  outstanding  commons stock.  Thus, some of the
     shares listed in the table might not be subject to purchase by a particular
     selling shareholder during that 60 day period, nonetheless those shares are
     included in this table. The actual number of shares of Class A Common Stock
     issuable upon the  conversion of the  Convertible  Debentures is subject to
     adjustment and could be significantly more than the number estimated in the
     table.  This  variation is due to factors that cannot be predicted by us at
     this time. The most significant of these factors is the future market price
     of the Class A Common Stock.

(3)  Includes   341,525   shares   issuable  upon  (A)  conversion  of  $342,500
     Convertible  Debentures and (B) the exercise of 146,368 Class I Warrants to
     purchase Class A Common Stock.

(4)  Includes 4,986 shares  issuable upon (A)  conversion of $5,000  Convertible
     Debentures and (B) the exercise of 2,137 Class I Warrants to purchase Class
     A Common Stock.
(5)  Includes   152,064   shares   issuable  upon  (A)  conversion  of  $152,500
     Convertible  Debentures  and (B) the exercise of 65,170 Class I Warrants to
     purchase Class A Common Stock.
(6)  Includes 99,715 shares issuable upon (A) conversion of $100,000 Convertible
     Debentures  and (B) the  exercise  of 42,735  Class I Warrants  to purchase
     Class A Common Stock.
(7)  Includes   398,860   shares   issuable  upon  (A)  conversion  of  $400,000
     Convertible  Debentures and (B) the exercise of 170,940 Class I Warrants to
     purchase Class A Common Stock.
(8)  Includes 150,000 shares issuable upon the exercise of Class J Warrants.
(9)  The  actual  number  of shares of Class A Common  Stock  issuable  upon the
     conversion of the Convertible  Debentures,  in payment of interest and upon
     exercise  of the Class I Warrants  is subject  to  adjustment  and could be
     materially  less or more  than the  number  estimated  in the  table.  This
     variation  is due to factors  that cannot be  predicted by us at this time.
     The most  significant  of these  factors is the future  market price of the
     common stock. In addition,  we may have to issue  additional  shares to the
     Debenture  holders based on  transactions we enter into with other parties.
     The terms of such transactions, if any, are not known at this time.
(10) The  number of shares  registered  for resale by each  selling  shareholder
     under this  Prospectus is equal to 254.173% of the amount  specified in the
     table to take into  account  the  floating  conversion  rate  described  in
     footnote  2 above,  the  amount of  interest  that might be paid in Class A
     Common Stock and the determination of the additional  shares, if any, which
     we may be obligated  to issue to the  Convertible  Debenture  holders if we
     engage in certain transactions before July 31, 2001.
(11) The  percentage  interest  of each  selling  shareholder  is  based  on the
     beneficial  ownership of that selling shareholder divided by the sum of the
     current  outstanding  shares of Class A Common  Stock  plus the  additional
     shares, if any, which would be issued to that selling  shareholder (but not
     any other selling  shareholder)  when  converting  Debentures or exercising
     Warrants or other right in the future. For purposes of presentation in this
     table,   the  9.99%  limit  referred  to  in  footnote  2  above  has  been
     disregarded.

                                 USE OF PROCEEDS

         The selling shareholders will receive the net proceeds from the sale of
their shares of common stock. We will not receive any proceeds from these sales.
We will however receive proceeds from the exercise of the Warrants. Each warrant
entitles  the holder to purchase  shares of common stock at a price of $2.20 per
share.  This purchase price is payable in cash or by surrendering  shares of our
common stock with an equal value. If all of the warrants are exercised for cash,
we will receive up to $1,270,000.

                              CERTAIN RELATIONSHIPS

         The selling shareholders each have a right to receive additional shares
of common stock if we issue equity or debt  securities at any time prior to July
31, 2001, at a discounted price greater than 80% of the fair market value of the
Class A Common Stock at the time of such  issuance.  Fahnestock & Co.,  Inc. has
the right of first refusal to act as placement  agent with respect to any future
private financings we may conduct during the one year period ending July 2000.

                         DETERMINATION OF OFFERING PRICE

         The selling  shareholders  may use this prospectus from time to time to
sell their common stock at a price  determined  by the  shareholder  selling the
common stock. 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  which  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.

         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.

                                       17
<PAGE>
         We are bearing all of the costs and expenses of registering  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.  Insofar as  indemnification  for
liabilities  arising  under the  securities  act may be permitted to  directors,
officers or persons controlling us, we have 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.  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 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.

                                  LEGAL MATTERS

         Certain legal matters have been passed upon for us by Squire, Sanders &
Dempsey L.L.P., Phoenix, Arizona.

                                     EXPERTS

         Our  financial  statements  as of June 30,  1999 and 1998,  and for the
years then ended,  have been  incorporated  by reference in this  Prospectus  in
reliance upon the report of KPMG LLP, independent  certified public accountants,
incorporated by reference herein, and upon the authority of said firm as experts
in accounting and auditing.

         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.

                     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 provides
legal  services to us. Mr. Adler owns options under the  Directors  Stock Option
Plan to  purchase  43,510  shares  of Class A Common  Stock at  exercise  prices
ranging  from $2.84 to $9.81.  As of August 20,  1999 these  shares  represented
approximately  1% of the  outstanding  shares  of the  Company's  Class A Common
Stock.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

         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 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.

ITEM 17. UNDERTAKINGS

         The undersigned Registrant hereby undertakes that:

         (1) For purposes of determining  any liability under the Securities Act
of 1933  (Securities  Act), the information  omitted from the form of prospectus
filed  as part of a  registration  statement  in  reliance  upon  Rule  430A and
contained in the form of  prospectus  filed by the  Registrant  pursuant to Rule
424(b)(1) or (4) or 497(h) under the  Securities  Act shall be deemed to be part
of this Registration Statement as of the time it was declared effective.

         (2) For purposes of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus 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) It will file,  during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement to:

       (i)    Include  any  prospectus  required  by  section  10(a)(3)  of  the
              Securities Act;

       (ii)   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; and

       (iii)  Include any additional or changed material information on the plan
              of  distribution  not  previously  disclosed  in the  Registration
              Statement.

         (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.

                          LIGHTPATH TECHNOLOGIES, INC.

6% CONVERTIBLE DEBENTURE DUE JULY 31, 2002

     THIS  DEBENTURE is one of a duly  authorized  issue of up to  $1,000,000 in
Debentures of LightPath Technologies, Inc., a corporation organized and existing
under the laws of the State of Delaware  (the  "COMPANY")  designated  as its 6%
Convertible  Debentures.  Such Debentures may be issued in series, each of which
may have a different  maturity  date,  but which  otherwise  have  substantially
similar  terms.  Capitalized  terms not defined  herein  shall have the meanings
ascribed to them in the Securities Purchase Agreement,  dated July ___, 1999, by
and among the  Company  and the Buyers (as that term is  defined  therein)  (the
"SECURITIES PURCHASE AGREEMENT").

     FOR VALUE RECEIVED, the Company promises to pay to  ______________________,
the   registered   holder   hereof  (the   "HOLDER"),   the   principal  sum  of
____________________  and 00/100 Dollars (US  $_______________) on July 31, 2002
(the "MATURITY  DATE") and to pay interest on the principal sum outstanding from
time to time in  arrears  (i) upon  conversion  as  provided  herein,  (ii) upon
redemption as provided  herein or (iii) on the Maturity  Date, at the rate of 6%
per annum  accruing  from July 28,  1999,  the date of initial  issuance of this
Debenture.  Accrual of interest shall commence on the first such business day to
occur after the date hereof and shall  continue to accrue on a daily basis until
payment in full of the principal sum has been made or duly provided for.

     This Debenture is subject to the following additional provisions:

          1. The  Debentures are issuable in  denominations  of Ten Thousand and
00/100 Dollars (US $10,000.00) and integral  multiples  thereof.  The Debentures
are  exchangeable  for an equal  aggregate  principal  amount of  Debentures  of

                                       1
<PAGE>
different authorized denominations,  as requested by the Holder surrendering the
same.  No service  charge  will be made for such  registration  or  transfer  or
exchange.

          2. The Company  shall be entitled  to  withhold  from all  payments of
principal  of, and  interest  on,  this  Debenture  any  amounts  required to be
withheld under the applicable provisions of the United States income tax laws or
other applicable laws at the time of such payments, and Holder shall execute and
deliver all required documentation in connection therewith.

          3.   This   Debenture   has  been   issued   subject   to   investment
representations  of the  original  purchaser  hereof and may be  transferred  or
exchanged  only in compliance  with the  Securities Act of 1933, as amended (the
"1933 ACT"),  and other  applicable  state and foreign  securities  laws. In the
event of any proposed transfer of this Debenture, the Company may require, prior
to issuance of a new Debenture in the name of such other person, that it receive
reasonable transfer documentation  including legal opinions that the issuance of
the  Debenture in such other name does not and will not cause a violation of the
1933  Act or any  applicable  state or  foreign  securities  laws.  Prior to due
presentment  for  transfer of this  Debenture,  the Company and any agent of the
Company may treat the person in whose name this Debenture is duly  registered on
the  Company's  Debenture  Register  as the  owner  hereof  for the  purpose  of
receiving payment as herein provided and for all other purposes,  whether or not
this  Debenture is overdue,  and neither the Company nor any such agent shall be
affected by notice to the contrary.

          4. (A) The  Holder  of this  Debenture  is  entitled,  at its  option,
subject to the  following  provisions  of this  Section  4, to convert  all or a
portion of this  Debenture  into shares of Class A Common  Stock of the Company,
$.01 par value per share ("COMMON  STOCK") of the Company at any time (except as
set  forth in this  Section  4(A) or in  Section  4(C)  hereunder)  prior to the
Maturity Date, at a conversion price (the "Conversion  Price") for each share of
Common  Stock equal to 80% of the Market Price of the Common Stock as of (X) the
Closing Date or (Y) the Conversion Date,  whichever is lower (but the Conversion
Price shall in no event be less than $0.56 (the "MINIMUM  CONVERSION  PRICE") or
more than $2.00),  as such amounts may be equitably  adjusted in accordance with
Sections 8, 9 and 10 hereof, if applicable. The minimum principal amount a Buyer
may  convert is the lower of (x) at least US  $10,000  (unless if at the time of
such  election  to convert  the  aggregate  principal  amount of all  Debentures
registered to the Holder is less than US $10,000, then the whole amount thereof)
or (y) the  maximum  amount  which the Holder can then  convert  pursuant to the
terms of Section 4(C) hereof.

             (B) Conversion  shall be  effectuated by  delivery by  facsimile or
other delivery to the Company of the form of conversion  notice  attached hereto
as EXHIBIT A executed by the Holder of the  Debenture  evidencing  such Holder's
intention to convert this Debenture or a specified  portion  hereof  ("NOTICE OF
CONVERSION"),  and accompanied, if required by the Company, by proper assignment
hereof in blank.  Subject to the  provisions  of Section 4(C)  hereof,  interest
accrued or accruing from the date of issuance to the date of  conversion  shall,
at the option of the Company, be paid in cash or Common Stock upon conversion at
the Conversion  Price  applicable to such  conversion.  No fractional  shares of
Common  Stock or scrip  representing  fractions  of  shares  will be  issued  on
conversion,  but the number of shares  issuable  shall be rounded to the nearest
whole share.  The date on which notice of conversion is given shall be deemed to

                                       2
<PAGE>
be the date on which  the  Holder  faxes or  otherwise  delivers  the  Notice of
Conversion, duly executed, to the Company (the "CONVERSION DATE"), provided that
the Holder shall deliver to the Company the original  Debentures being converted
within five (5) business days  thereafter.  Facsimile  delivery of the Notice of
Conversion  shall be accepted by the Company at facsimile number (505) 342-1111;
ATTN: PRESIDENT.  Certificates representing Common Stock upon conversion will be
delivered within three (3) business days following the Conversion Date.

         (C)  Notwithstanding  any other provision hereof, of the Warrants or of
any of the other  Transaction  Agreements  (as those  terms are  defined  in the
Securities  Purchase  Agreement),  in no event  (except  (i) with  respect to an
automatic  or  mandatory  conversion,  if any, of a Debenture as provided in the
Debentures,  (ii) as specifically  provided in this Debenture as an exception to
this  provision,  or (iii) while there is  outstanding a tender offer for any or
all of the shares of the Company's Common Stock) shall the Holder be entitled to
convert any Debenture or shall the Company have the  obligation,  to convert all
or any portion of this  Debenture  (and the Company  shall not have the right to
pay interest on this Debenture in the form of Common Stock ) to the extent that,
after  such  conversion,  the sum of (1) the  number of  shares of Common  Stock
beneficially owned by the Holder and its affiliates (other than shares of Common
Stock  which may be deemed  beneficially  owned  through  the  ownership  of the
unconverted  portion of the Debentures or unexercised  portion of the Warrants),
and (2) the number of shares of Common Stock issuable upon the conversion of the
Debentures or exercise of the Warrants  with respect to which the  determination
of this  proviso is being made,  would  result in  beneficial  ownership  by the
Holder and its affiliates of more than 9.99% of the outstanding shares of Common
Stock (after taking into account the shares to be issued to the Holder upon such
conversion  or  exercise).  For  purposes  of the  proviso  to  the  immediately
preceding sentence,  beneficial ownership shall be determined in accordance with
Section  13(d) of the  Securities  Exchange  Act of 1934,  as amended (the "1934
ACT"), except as otherwise provided in clause (1) of such sentence.  The Holder,
by its acceptance of this Debenture, further agrees that if the Holder transfers
or assigns any of the Debentures to a party who or which would not be considered
such an affiliate,  such assignment shall be made subject to the transferee's or
assignee's specific agreement to be bound by the provisions of this Section 4(C)
as if such transferee or assignee were the original Holder hereof.

         (D) The Holder recognizes that the Company may be limited in the number
of shares of Common Stock it may issue by (i) reason of its  authorized  shares,
or (ii) the applicable rules and regulations of the principal  securities market
on  which  the  Common  Stock  is  listed  or  traded  (collectively,  the  "CAP
REGULATIONS").  Without  limiting the other provisions  hereof,  (i) the Company
will take all steps reasonably  necessary to be in a position to issue shares of
Common  Stock  on  conversion  of  the  Debentures  without  violating  the  Cap
Regulations  and (ii) if,  despite  taking such steps,  the Company still cannot
issue such shares of Common Stock  without  violating the Cap  Regulations,  the
Holder  of this  Debenture  (to the  extent  the  same can not be  converted  in
compliance with the Cap Regulations (an  "UNCONVERTED  DEBENTURE")),  shall have
the option,  exercisable in the Holder's sole and absolute discretion,  to elect
any one of the following remedies:

               (x) if permitted by the Cap  Regulations,  require the Company to
          issue shares of Common Stock in accordance  with such Holder's  Notice

                                       3
<PAGE>
          of Conversion  relating to the  Unconverted  Debenture at a conversion
          purchase price equal to the average of the closing bid price per share
          of Common Stock for any five (5) consecutive  trading days (subject to
          the equitable  adjustments  for certain events  occurring  during such
          period as provided in this  Debenture)  during the sixty (60)  trading
          days immediately preceding the date of the Notice of Conversion; or

               (y) require the Company to redeem each Unconverted  Debenture for
          an amount (the "CAP REDEMPTION AMOUNT"), payable in cash, equal to:

                                    V        x       M
                                  -----
                                    CP

               where:

               "V" means the outstanding principal plus accrued interest through
          the  Cap  Redemption   Date  (as  defined  below)  of  an  Unconverted
          Debenture;

               "CP"  means  the  Conversion  Price  in  effect  on the  date  of
          redemption  (the "CAP REDEMPTION  DATE")  specified in the notice from
          the Holder electing this remedy; and

               "M"  means  the  highest  closing  ask price  during  the  period
          beginning on the Cap Redemption Date and ending on the date of payment
          of the Cap Redemption Amount.

The holder of an Unconverted  Debenture may elect one of the above remedies with
respect to a portion of such  Unconverted  Debenture  and the other  remedy with
respect to other portions of the Unconverted Debenture.

          (E) Anything herein to the contrary notwithstanding,  in the event the
Company  breaches  the  provisions  of Section 4(f) of the  Securities  Purchase
Agreement,  the  Conversion  Price  shall be  amended  to be equal to 90% of the
Conversion  Price  determined in accordance with Section 4(A) of this Debenture,
and the Holder may  require the Company to  immediately  redeem the  outstanding
portion of this Debenture in accordance with clause (y) of Section 4(D).


          (F) Any Debentures  not previously  converted as of the Maturity Date,
shall be deemed to be  automatically  converted,  without  further action of any
kind by the Company or any of its agents,  employees or  representatives,  as of
the Maturity  Date at the  Conversion  Price  applicable  on the  Maturity  Date
("MANDATORY CONVERSION").

     5.  REDEMPTION.  This  Debenture  can be redeemed for cash at any time,  in
whole or in part, by the Company. To redeem the Debenture,  the Company must (i)
send a  written  notice to the  Holder  not less than five (5) nor more than ten
(10) business days prior to the date on which it wishes to redeem the Debenture,
and (ii) pay the Holder  cash or  immediately  available  funds in the amount of

                                       4
<PAGE>
115% times the  principal  amount of the  Debenture  then  outstanding  plus all
accrued but unpaid interest. If the Company does not pay the redemption price to
the Holder on or before the date of  redemption  specified  in the  notice,  the
Holder will have the right to deem such notice of redemption to be null and void
and the Company will lose its right to further redeem this  Debenture.  A holder
may convert all or any part of this Debenture up to the amount redeemed pursuant
to such notice at any time during the first five (5) business days following the
notice of redemption and without regard to the provisions of Section 4(C).

     6. Subject to the terms of the Securities Purchase Agreement,  no provision
of this Debenture shall alter or impair the obligation of the Company,  which is
absolute  and  unconditional,  to pay the  principal  of, and  interest on, this
Debenture at the time,  place,  and rate,  and in the coin or  currency,  herein
prescribed.  This Debenture and all other  Debentures now or hereafter issued of
similar terms are direct obligations of the Company.

     7. No  recourse  shall be had for the payment of the  principal  of, or the
interest  on, this  Debenture,  or for any claim based  hereon,  or otherwise in
respect hereof, against any incorporator,  shareholder,  officer or director, as
such,  past,  present or future,  of the Company or any  successor  corporation,
whether  by  virtue  of any  constitution,  statute  or rule  of law,  or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance  hereof and as part of the consideration for the issue hereof,
expressly waived and released.

     8. If the Company merges or consolidates with another  corporation or sells
or transfers all or  substantially  all of its assets to another  person and the
holders  of the  Common  Stock are  entitled  to receive  stock,  securities  or
property in respect of or in exchange for Common  Stock,  then as a condition of
such  merger,  consolidation,  sale  or  transfer,  the  Company  and  any  such
successor,  purchaser or transferee  agree that the Debenture may  thereafter be
converted  on the terms and subject to the  conditions  set forth above into the
kind and amount of stock,  securities or property  receivable  upon such merger,
consolidation,  sale or  transfer  by a holder of the number of shares of Common
Stock into which this  Debenture  might have been converted  immediately  before
such merger, consolidation, sale or transfer, subject to adjustments which shall
be as nearly  equivalent  as may be  practicable.  In the event of any  proposed
merger,  consolidation  or sale or transfer of all or  substantially  all of the
assets of the  Company (a  "SALE"),  the Holder  hereof  shall have the right to
convert this  Debenture  by  delivering  a Notice of  Conversion  to the Company
within fifteen (15) days of receipt of notice of such Sale from the Company.  In
the event the Holder  hereof  elects not to convert,  the Company may prepay all
outstanding principal and accrued interest on this Debenture pursuant to Section
5 hereof, less all amounts required by law to be deducted,  upon which tender of
payment following such notice, the right of conversion shall terminate.

     9. If, for any reason,  prior to the conversion or redemption,  the Company
spins off or otherwise divests itself of a part of its business or operations or
disposes all of or a substantial  part of its assets in a transaction (the "SPIN
OFF") in which the Company  does not  receive  compensation  for such  business,
operations or assets,  but causes  securities  of another  entity (the "SPIN OFF
SECURITIES") to be issued to security  holders of the Company,  then the Company
shall cause (i) to be reserved Spin Off  Securities  equal to the number thereof
which  would have been issued to the Holder had all of the  Holder's  Debentures
outstanding  on the record date (the "RECORD DATE") for  determining  the amount
and  number  of Spin Off  Securities  to be issued to  security  holders  of the

                                       5
<PAGE>
Company  (the  "OUTSTANDING  DEBENTURES")  been  converted  as of the  close  of
business on the trading day  immediately  before the Record Date (the  "RESERVED
SPIN OFF SHARES"),  and (ii) to be issued to the Holder on the conversion of all
or any of the  Outstanding  Debentures,  such  amount of the  Reserved  Spin Off
Shares equal to (x) the Reserved  Spin Off Shares  multiplied by (y) a fraction,
of which (I) the numerator is the principal amount of the Outstanding Debentures
then being  converted,  and (II) the denominator is the principal  amount of the
Outstanding Debentures.

     10.  If,  at  any  time  while  any  portion  of  this  Debenture   remains
outstanding, the Company effectuates a stock split or reverse stock split of its
Common  Stock or issues a dividend on its Common Stock  consisting  of shares of
Common Stock, the Conversion  Price shall be equitably  adjusted to reflect such
action. By way of illustration,  and not in limitation, of the foregoing: (i) if
the  Company  effectuates  a 2:1 split of its  Common  Stock,  thereafter,  with
respect to any  conversion  for which the  Company  issues the shares  after the
record date of such split,  the Conversion  Price shall be deemed to be one-half
of the  Conversion  Price  calculated  in  Section  4(A);  (ii)  if the  Company
effectuates a 1:10 reverse split of its Common Stock,  thereafter,  with respect
to any  conversion for which the Company issues the shares after the record date
of such reverse split,  the Conversion Price shall be deemed to be ten times the
Conversion Price calculated in Section 4(A); and (iii) if the Company declares a
stock  dividend  of one share of Common  Stock for every 10 shares  outstanding,
thereafter,  with  respect to any  conversion  for which the Company  issues the
shares after the record date of such  dividend,  the  Conversion  Price shall be
deemed  to be the  amount of the  Conversion  Price  calculated  in  Section  4A
multiplied  by a fraction,  of which the  numerator is the number of shares (10)
for which a dividend share will be issued and the  denominator is such number of
shares plus the  dividend  share(s)  issuable or issued  thereon  (11).

     11. All payments  contemplated hereby to be made "in cash" shall be made in
immediately  available  good funds in such coin or currency of the United States
of America as at the time of payment is legal  tender for  payment of public and
private debts.  All payments of cash and each delivery of shares of Common Stock
issuable to the Holder as contemplated hereby shall be made to the Holder at the
address last appearing on the Debenture Register of the Company as designated in
writing by the Holder from time to time;  except that the Holder can  designate,
by notice to the  Company,  a  different  delivery  address  for any one or more
specific payments or deliveries.

     12. The Holder of the  Debenture,  by acceptance  hereof,  agrees that this
Debenture is being  acquired for  investment  purposes and that such Holder will
not offer,  sell or otherwise  dispose of this Debenture or the Shares of Common
Stock issuable upon conversion thereof except under circumstances which will not
result in a  violation  of the Act or any  applicable  state Blue Sky or foreign
laws or similar laws relating to the sale of securities.

     13. This  Debenture  shall be governed by and construed in accordance  with
the  laws  of the  State  of  Delaware.  Each  of the  parties  consents  to the
jurisdiction  of the federal  courts whose  districts  encompass any part of the
City of Wilmington  or the state courts of the State of Delaware  sitting in the
City of Wilmington in connection  with any dispute  arising under this Agreement
and hereby  waives,  to the maximum  extent  permitted  by law,  any  objection,
including any  objection  based on FORUM NON  COVENIENS,  to the bringing of any
such proceeding in such  jurisdictions.  To the extent determined by such court,

                                       6
<PAGE>
the  Company  shall  reimburse  the  Holder  for any  reasonable  legal fees and
disbursements  incurred by the Holder in  enforcement of or protection of any of
its rights under any of this Debenture.

     14. The following shall constitute an "Event of Default":

               a. The  Company  shall  default in the  payment of  principal  or
          interest on this Debenture and same shall continue for a period of ten
          (10) days; or

               b. Any of the  representations  or warranties made by the Company
          herein, in the Securities Purchase Agreement,  the Registration Rights
          Agreement  or  in  any  certificate  or  financial  or  other  written
          statements  heretofore  or  hereafter  furnished  by  the  Company  in
          connection  with the execution  and delivery of this  Debenture or the
          Securities  Purchase  Agreement  shall be false or  misleading  in any
          material respect at the time made; or

               c. The  Company  fails to issue  shares  of  Common  Stock to the
          Holder or to cause its Transfer  Agent to issue shares of Common Stock
          upon exercise by the Holder of the conversion  rights of the Holder in
          accordance with the terms of this  Debenture,  fails to transfer or to
          cause its  Transfer  Agent to transfer any  certificate  for shares of
          Common Stock issued to the Holder upon  conversion  of this  Debenture
          and  when  required  by  this  Debenture  or the  Registration  Rights
          Agreement,  and such transfer is otherwise  lawful, or fails to remove
          any  restrictive  legend or to cause its Transfer Agent to transfer on
          any  certificate  or any shares of Common  Stock  issued to the Holder
          upon  conversion  of  this  Debenture  as and  when  required  by this
          Debenture, the Agreement or the Registration Rights Agreement and such
          legend  removal  is  otherwise  lawful,  and any  such  failure  shall
          continue uncured for five (5) business days.

               d. The Company shall fail to perform or observe,  in any material
          respect, any other covenant, term, provision,  condition, agreement or
          obligation  of any  Debenture  in this series and such  failure  shall
          continue uncured for a period of thirty (30) days after written notice
          from the Holder of such failure; or

               e. The Company shall fail to perform or observe,  in any material
          respect,  any  covenant,  term,  provision,  condition,  agreement  or
          obligation of the Company under the Securities  Purchase  Agreement or
          the  Registration  Rights  Agreement and such failure  shall  continue
          uncured for a period of thirty (30) days after written notice from the
          Holder of such failure (other than a failure to cause the Registration

                                       7
<PAGE>
          Statement to become  effective  no later than the  Required  Effective
          Date, as defined and provided in the Registration Rights Agreement, as
          to which no such cure period shall apply); or

               f. The Company  shall (1) admit in writing its  inability  to pay
          its debts  generally as they mature;  (2) make an  assignment  for the
          benefit of creditors or commence  proceedings for its dissolution;  or

          or  receiver  for its or for a  substantial  part of its  property  or
          business; or

               g. A trustee,  liquidator or receiver  shall be appointed for the
          Company or for a substantial  part of its property or business without
          its consent and shall not be  discharged  within sixty (60) days after
          such appointment; or

               h. Any governmental agency or any court of competent jurisdiction
          at the instance of any  governmental  agency  shall assume  custody or
          control of the whole or any  substantial  portion of the properties or
          assets of the Company  and shall not be  dismissed  within  sixty (60)
          days thereafter; or

               i. Any money judgment, writ or warrant of attachment,  or similar
          process in excess of Two Hundred  Thousand  ($200,000)  Dollars in the
          aggregate  shall be entered or filed against the Company or any of its
          properties  or  other  assets  and  shall  remain  unpaid,  unvacated,
          unbonded or  unstayed  for a period of sixty (60) days or in any event
          later  than  five (5) days  prior  to the  date of any  proposed  sale
          thereunder; or

               j.   Bankruptcy,   reorganization,   insolvency  or   liquidation
          proceedings or other  proceedings  for relief under any bankruptcy law
          or any law for the relief of debtors shall be instituted by or against
          the Company  and, if  instituted  against  the  Company,  shall not be
          dismissed or stayed within sixty (60) days after such  institution  or
          the Company shall by any action or answer  approve of,  consent to, or
          acquiesce in any such  proceedings  or admit the material  allegations
          of, or default in answering a petition  filed in any such  proceeding;
          or

               k. The Company shall have its Common Stock  suspended or delisted
          from an exchange or over-the-counter market from trading for in excess
          of five (5) trading days; or

               l. The Company fails to file the  Registration  Statement  within
          sixty  (60)  days  following  the  Closing  Date  or the  Registration

                                       8
<PAGE>
          Statement is not  declared  effective  within one hundred  fifty (150)
          days following the Closing Date.

Then, or at any time  thereafter,  and in each and every such case,  unless such
Event of Default  shall have been waived in writing by the Holder  (which waiver
shall not be deemed to be a waiver of any  subsequent  default) at the option of
the Holder and in the Holder's  sole  discretion,  the Holder may consider  this
Debenture immediately due and payable,  without presentment,  demand, protest or
notice of any kinds, all of which are hereby expressly  waived,  anything herein
or in any note or other instruments  contained to the contrary  notwithstanding,
and the Holder may  immediately  enforce any and all of the Holder's  rights and
remedies provided herein or any other rights or remedies afforded by law.

     15. Nothing  contained in this  Debenture  shall be construed as conferring
upon the  Holder  the right to vote or to  receive  dividends  or to  consent or
receive notice as a shareholder in respect of any meeting of shareholders or any
rights  whatsoever  as a  shareholder  of the Company,  unless and to the extent
converted in accordance with the terms hereof.

     16. In the event for any  reason,  any  payment by or act of the Company or
the Holder  shall  result in payment of interest  which  would  exceed the limit
authorized  by or be in violation of the law of the  jurisdiction  applicable to
this  Debenture,  the  obligation of the Company to pay interest or perform such
act or requirement  shall be reduced to the limit  authorized under such law, so
that in no event  shall  the  Company  be  obligated  to pay any such  interest,
perform any such act or be bound by any  requirement  which would  result in the
payment  of  interest  in excess of the  limit so  authorized.  In the event any
payment by or act of the Company  shall  result in the  extraction  of a rate of
interest in excess of a sum which is lawfully collectible as interest, then such
amount (to the extent of such excess not returned to the Company) shall, without
further  agreement or notice between or by the Company or the Holder,  be deemed
applied to the payment of principal,  if any, hereunder immediately upon receipt
of such excess funds by the Holder, with the same force and effect as though the
Company had specifically  designated such sums to be so applied to principal and
the Holder had agreed to accept such sums as an interest-free prepayment of this
Debenture.  If any part of such excess remains after the principal has been paid
in full, whether by the provisions of the preceding sentences of this Section 16
or otherwise,  such excess shall be deemed to be an interest-free  loan from the
Company to the Holder,  which loan shall be payable  immediately  upon demand by
the  Company.  The  provisions  of this  Section 16 shall  control  every  other
provision of this Debenture.

                                       9

     IN WITNESS  WHEREOF,  the  Company has caused  this  instrument  to be duly
executed by an officer thereunto duly authorized.

     1. ISSUANCE; CERTAIN DEFINITIONS.

          In  consideration of good and valuable  consideration,  the receipt of

for the shares of Common Stock so purchased. For the purposes of this Section 2,
"Market  Value" shall be an amount equal to the Market Price of the Common Stock
on the day immediately preceding the Company's receipt of the Notice of Exercise
Form duly  executed,  multiplied  by the number of shares of Common  Stock to be
issued upon surrender of this Warrant Certificate.

- ----------
(1)  Number  of shares = (the  Purchase  Price of the  Debentures  issued to the
Holder on the  Closing  Date / the  Conversion  Price of the  Debentures  on the
Closing Date) x 75%.

          2.2.  LIMITATION ON EXERCISE.  Notwithstanding  the provisions of this
Warrant,  the Securities Purchase Agreement or the other Transaction  Agreements
(as defined in the Securities  Purchase  Agreement),  the Holder cannot exercise
this  Warrant,  nor shall the Company have the  obligation  to issue shares upon
such exercise of all or any portion of this Warrant,  to the extent that,  after
such  exercise the sum of (1) the number of shares of Common Stock  beneficially
owned by the Holder and its affiliates  (other than shares of Common Stock which
may be deemed  beneficially  owned  through  the  ownership  of the  unconverted
portion of the Debenture or unexercised  portion of the  Warrants),  and (2) the
number of shares of Common Stock issuable upon the exercise of the Warrants with
respect to which the  determination  of this proviso is being made, would result
in beneficial  ownership by the Holder and its  affiliates of more than 9.99% of
the outstanding  shares of Common Stock (after taking into account the shares to
be  issued  to  the  Holder  upon  such  exercise),  subject  to  the  following
exceptions:

          (i) as  specifically  provided in this Warrant as an exception to this
     provision, or

          (ii) while there is  outstanding  a tender offer for any or all of the
     shares of the Company's Common Stock.

For purposes of this Section 2.2,  beneficial  ownership  shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended
(the "1934  ACT"),  except as  otherwise  provided in clause (1) of this Section
2.2. The Holder,  by its acceptance of this Warrant,  further agrees that if the
Holder  transfers  or assigns any of the  Warrants to a party who or which would
not be considered such an affiliate,  such  assignment  shall be made subject to
the transferee's or assignee's  specific agreement to be bound by the provisions
of this Section 2.2 as if such  transferee or assignee were the original  Holder
hereof.

     3.  RESERVATION  OF SHARES.  The  Company  hereby  agrees that at all times
during the term of this Warrant it will reserve for  issuance  upon  exercise of
this  Warrant  such number of shares of its Common  Stock as may be required for
issuance upon exercise of this Warrant (the "Warrant Shares").

     4.  MUTILATION  OR LOSS OF  WARRANT.  (a) Upon  receipt  by the  Company of
evidence  satisfactory to it of the loss, theft, or destruction of this Warrant,
and receipt of reasonably  satisfactory  indemnification,  or (b) in the case of
mutilation,  upon surrender and  cancellation of this Warrant,  the Company will
execute  and  deliver a new  Warrant  of like  tenor and date and any such lost,
stolen, destroyed or mutilated Warrant shall thereupon become void.

     5.  RIGHTS OF THE  HOLDER.  The Holder  shall  not,  by virtue  hereof,  be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those  expressed in this Warrant and
are not enforceable against the Company except to the extent set forth herein.

     6. PROTECTION AGAINST DILUTION.

          6.1. ADJUSTMENT  MECHANISM.  If an adjustment of the Exercise Price is
required  pursuant to this  Section 6, the Holder  shall be entitled to purchase
such number of additional  shares of Common Stock as will cause the total number
of shares of Common  Stock  Holder is  entitled  to  purchase  pursuant  to this
Warrant,  multiplied  by the  adjusted  Exercise  Price per share,  to equal the
dollar  amount of the total  number of shares of Common Stock Holder is entitled
to purchase  before  adjustment  multiplied by the total  Exercise  Price before
adjustment.

          6.2. CAPITAL ADJUSTMENTS.  In case of any stock split or reverse stock
split, stock dividend,  reclassification of the Common Stock,  recapitalization,
merger or consolidation,  or like capital adjustment  affecting the Common Stock
of the  Company,  the  provisions  of this Section 6 shall be applied as if such
capital  adjustment  event had  occurred  immediately  prior to the date of this
Warrant and the original  Exercise Price had been fairly  allocated to the stock
resulting from such capital adjustment;  and in other respects the provisions of
this Section shall be applied in a fair,  equitable and reasonable  manner so as
to give effect,  as nearly as may be, to the purposes  hereof. A rights offering
to  stockholders  shall be deemed a stock  dividend to the extent of the bargain
purchase element of the rights.

                                       -2-
<PAGE>
          6.3.  ADJUSTMENT  FOR  SPIN  OFF.  If,  for any  reason,  prior to the
exercise of this Warrant in full,  the Company  spins off or  otherwise  divests
itself of a substantial part of its business or operations or disposes of all or
substantially  all of its assets in a transaction  (the "SPIN OFF") in which the
Company does not receive  compensation for such business,  operations or assets,
but causes securities of another entity (the "SPIN OFF SECURITIES") to be issued
to security holders of the Company, then;

          (a) the Company  shall cause (i) to be  reserved  Spin Off  Securities
     equal to the number  which  would have been issued to the Holder had all of
     the  Holder's  unexercised  Warrants  outstanding  on the record  date (the
     "RECORD DATE") for determining the amount and number of Spin Off Securities
     to  be  issued  to  security  holders  of  the  Company  (the  "OUTSTANDING
     WARRANTS")  been  exercised  as of the close of business on the trading day
     immediately  before the Record Date (the "RESERVED  SPIN OFF SHARES"),  and
     (ii)  to be  issued  to the  Holder  on the  exercise  of all or any of the
     Outstanding Warrants,  such amount of the Reserved Spin Off Shares equal to
     (x) the Reserved Spin Off Shares multiplied by (y) a fraction, of which (I)
     the  numerator  is  the  amount  of the  Outstanding  Warrants  then  being
     exercised,  and (II)  the  denominator  is the  amount  of the  Outstanding
     Warrants; and

          (b) the Exercise Price on the  Outstanding  Warrants shall be adjusted
     immediately after  consummation of the Spin Off by multiplying the Exercise
     Price by a  fraction,  the  numerator  of which is the Market  Price of the
     Common Stock on the eleventh  trading day  immediately  following the fifth
     trading  day after the Record  Date,  and the  denominator  of which is the
     Market  Price of the Common  Stock on the Record  Date;  and such  adjusted
     Exercise Price shall be deemed to be the Exercise Price with respect to the
     Outstanding  Warrants after the Record Date.

     7. TRANSFER TO COMPLY WITH THE SECURITIES ACT; REGISTRATION RIGHTS.

          7.1.  TRANSFER.  This  Warrant  has  not  been  registered  under  the
Securities Act of 1933, as amended,  (the "1933 ACT") and has been issued to the
Holder  for  investment  and not with a view to the  distribution  of either the

                                 FORM OF WARRANT

THESE  SECURITIES AND THE SECURITIES  ISSUABLE UPON THEIR EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 (the "1933 Act," AS AMENDED, AND MAY
NOT BE TRANSFERRED UNLESS COVERED BY AN EFFECTIVE  REGISTRATION  STATEMENT UNDER

                          LIGHTPATH TECHNOLOGIES, INC.

                      COMMON STOCK PURCHASE CLASS J WARRANT

1. ISSUANCE; CERTAIN DEFINITIONS.

          In  consideration of good and valuable  consideration,  the receipt of
which is  hereby  acknowledged  by  LightPath  Technologies,  Inc.,  a  Delaware
corporation (the "Company"),  Fahnestock & Co., Inc. or registered  assigns (the
"Holder")  is hereby  granted the right to purchase at any time until 5:00 P.M.,
New York City time, on July 31, 2004, (the "Expiration Date"), One Hundred Fifty
Thousand (150,000) fully paid and nonassessable  shares of the Company's Class A
Common  Stock,  par value  $0.01 per share  (the  "Common  Stock") at an initial
exercise  price per share (the  "Exercise  Price") of $2.20,  subject to further
adjustment  as set forth  herein.  This Warrant is being issued  pursuant to the
terms of that certain Securities Purchase  Agreement,  dated as of July 28, 1999
(the  "Securities  Purchase  Agreement"),  to which the  Company  and Holder (or
Holder's  predecessor  in interest) are parties.  Capitalized  terms not defined
herein  shall have the  meanings  ascribed  to them in the  Securities  Purchase
Agreement.

2. EXERCISE OF WARRANTS.

          2.1 GENERAL.  This Warrant is  exercisable  in whole or in part at any
time and from time to time at the  Exercise  Price  per  share of  Common  Stock
payable hereunder, payable in cash or by certified or official bank check, or by
"cashless  exercise,"  by means of  tendering  this Warrant  Certificate  to the
Company to receive a number of shares of Common  Stock equal in Market  Value to
the  difference  between the Market Value of the shares of Common Stock issuable
upon exercise of this Warrant and the total cash exercise  price  thereof.  Upon
surrender of this Warrant  Certificate with the attached Notice of Exercise Form
duly executed (which Notice of Exercise Form may be submitted either by delivery
to the Company or by  facsimile  transmission  as provided in Section 8 hereof),
together  with  payment of the  Exercise  Price for the  shares of Common  Stock
purchased, the Holder shall be entitled to receive a certificate or certificates
for the shares of Common Stock so purchased. For the purposes of this Section 2,
"Market  Value" shall be an amount equal to the Market Price of the Common Stock
on the day immediately preceding the Company's receipt of the Notice of Exercise
Form duly  executed,  multiplied  by the number of shares of Common  Stock to be
issued upon surrender of this Warrant Certificate.

          2.2  LIMITATION ON EXERCISE.  Notwithstanding  the  provisions of this
Warrant,  the Securities Purchase Agreement or the other Transaction  Agreements
(as defined in the Securities  Purchase  Agreement),  the Holder cannot exercise
this  Warrant,  nor shall the Company have the  obligation  to issue shares upon
such exercise of all or any portion of this Warrant,  to the extent that,  after
such  exercise the sum of (1) the number of shares of Common Stock  beneficially
owned by the Holder and its affiliates  (other than shares of Common Stock which
may be deemed  beneficially  owned  through  the  ownership  of the  unconverted
portion of the Debenture or unexercised  portion of the  Warrants),  and (2) the
number of shares of Common Stock issuable upon the exercise of the Warrants with
respect to which the  determination  of this proviso is being made, would result
in beneficial  ownership by the Holder and its  affiliates of more than 9.99% of
the outstanding  shares of Common Stock (after taking into account the shares to
be  issued  to  the  Holder  upon  such  exercise),  subject  to  the  following
exceptions:

                                       -1-
<PAGE>
          (i) as  specifically  provided in this Warrant as an exception to this
     provision, or

          (ii) while there is  outstanding  a tender offer for any or all of the
     shares of the Company's Common Stock.

For purposes of this Section 2.2,  beneficial  ownership  shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended
(the "1934  ACT"),  except as  otherwise  provided in clause (1) of this Section
2.2. The Holder,  by its acceptance of this Warrant,  further agrees that if the
Holder  transfers  or assigns any of the  Warrants to a party who or which would
not be considered such an affiliate,  such  assignment  shall be made subject to
the transferee's or assignee's  specific agreement to be bound by the provisions
of this Section 2.2 as if such  transferee or assignee were the original  Holder
hereof.

3. RESERVATION OF SHARES. The Company hereby agrees that at all times during the
term of this Warrant it will reserve for issuance  upon exercise of this Warrant
such number of shares of its Common Stock as may be required  for issuance  upon
exercise of this Warrant (the "WARRANT SHARES").

4.  MUTILATION  OR LOSS OF WARRANT.  (a) Upon receipt by the Company of evidence
satisfactory  to it of the loss,  theft,  or  destruction  of this Warrant,  and
receipt  of  reasonably  satisfactory  indemnification,  or (b) in the  case  of
mutilation,  upon surrender and  cancellation of this Warrant,  the Company will
execute  and  deliver a new  Warrant  of like  tenor and date and any such lost,
stolen, destroyed or mutilated Warrant shall thereupon become void.

5. RIGHTS OF THE HOLDER.  The Holder shall not, by virtue hereof, be entitled to
any rights of a  stockholder  in the Company,  either at law or equity,  and the
rights of the Holder are limited to those  expressed in this Warrant and are not
enforceable against the Company except to the extent set forth herein.

6. PROTECTION AGAINST DILUTION.

     6.1  ADJUSTMENT  MECHANISM.  If an  adjustment  of the  Exercise  Price  is
required  pursuant to this  Section 6, the Holder  shall be entitled to purchase
such number of additional  shares of Common Stock as will cause the total number
of shares of Common  Stock  Holder is  entitled  to  purchase  pursuant  to this
Warrant,  multiplied  by the  adjusted  Exercise  Price per share,  to equal the
dollar  amount of the total  number of shares of Common Stock Holder is entitled
to purchase  before  adjustment  multiplied by the total  Exercise  Price before
adjustment.

     6.2 CAPITAL ADJUSTMENTS. In case of any stock split or reverse stock split,
stock dividend,  reclassification of the Common Stock, recapitalization,  merger
or consolidation,  or like capital adjustment  affecting the Common Stock of the
Company,  the  provisions  of this Section 6 shall be applied as if such capital
adjustment event had occurred  immediately prior to the date of this Warrant and
the original  Exercise  Price had been fairly  allocated to the stock  resulting
from such  capital  adjustment;  and in other  respects the  provisions  of this
Section  shall be applied in a fair,  equitable and  reasonable  manner so as to
give effect,  as nearly as may be, to the purposes  hereof. A rights offering to
stockholders  shall be deemed a stock  dividend  to the  extent  of the  bargain
purchase element of the rights.

     6.3 ADJUSTMENT  FOR SPIN OFF. If, for any reason,  prior to the exercise of
this Warrant in full,  the Company  spins off or otherwise  divests  itself of a
substantial   part  of  its  business  or  operations  or  disposes  of  all  or
substantially  all of its assets in a transaction  (the "SPIN OFF") in which the
Company does not receive  compensation for such business,  operations or assets,
but causes securities of another entity (the "SPIN OFF SECURITIES") to be issued
to security holders of the Company, then;

          (a) the Company  shall cause (i) to be  reserved  Spin Off  Securities
     equal to the number  which  would have been issued to the Holder had all of
     the  Holder's  unexercised  Warrants  outstanding  on the record  date (the
     "RECORD DATE") for determining the amount and number of Spin Off Securities
     to  be  issued  to  security  holders  of  the  Company  (the  "OUTSTANDING
     WARRANTS")  been  exercised  as of the close of business on the trading day
     immediately  before the Record Date (the "RESERVED  SPIN OFF SHARES"),  and
     (ii)  to be  issued  to the  Holder  on the  exercise  of all or any of the
     Outstanding Warrants,  such amount of the Reserved Spin Off Shares equal to
     (x) the Reserved Spin Off Shares multiplied by (y) a fraction, of which (I)
     the  numerator  is  the  amount  of the  Outstanding  Warrants  then  being
     exercised,  and (II)  the  denominator  is the  amount  of the  Outstanding
     Warrants; and

                                       -2-
<PAGE>
          (b) the Exercise Price on the  Outstanding  Warrants shall be adjusted
     immediately after  consummation of the Spin Off by multiplying the Exercise
     Price by a  fraction,  the  numerator  of which is the Market  Price of the
     Common Stock on the eleventh  trading day  immediately  following the fifth
     trading  day after the Record  Date,  and the  denominator  of which is the
     Market  Price of the Common  Stock on the Record  Date;  and such  adjusted
     Exercise Price shall be deemed to be the Exercise Price with respect to the
     Outstanding  Warrants after the Record Date.

7.   TRANSFER TO COMPLY WITH THE SECURITIES ACT; REGISTRATION RIGHTS.

     7.1 TRANSFER. This Warrant has not been registered under the Securities Act
of 1933,  as  amended,  (the "1933  Act") and has been  issued to the Holder for
investment and not with a view to the  distribution of either the Warrant or the
Warrant Shares.  Neither this Warrant nor any of the Warrant Shares or any other
security  issued  or  issuable  upon  exercise  of  this  Warrant  may be  sold,
transferred, pledged or hypothecated in the absence of an effective registration
statement  under the 1933 Act relating to such security or an opinion of counsel
satisfactory  to the Company that  registration  is not required  under the 1933
Act. Each certificate for the Warrant, the Warrant Shares and any other security
issued or issuable  upon exercise of this Warrant shall contain a legend in form
and  substance  satisfactory  to  counsel  for the  Company,  setting  forth the
restrictions on transfer contained in this Section.

     7.2  REGISTRATION  RIGHTS.  Reference  is made to the  Registration  Rights
Agreement (as that term is defined in the Securities  Purchase  Agreement).  The
Company's  obligations  under the  Registration  Rights  Agreement and the other
terms and conditions thereof with respect to the Warrant Shares,  including, but
not  necessarily  limited to, the Company's  commitment  to file a  registration
statement  including the Warrant Shares, to have the registration of the Warrant
Shares  completed  and  effective,  and  to  maintain  such  registration,   are
incorporated herein by reference.

RE:  LightPath Technologies, Inc.

Dear Ladies and Gentlemen:

         This firm is  counsel  for  LightPath  Technologies,  Inc.,  a Delaware
corporation  (the  "Company").  As such, we are familiar with the Certificate of
Incorporation,  as amended,  and Bylaws of the Company,  as well as  resolutions
adopted by its Board of Directors authorizing the issuance and sale of 2,684,500
shares of the  Company's  $.01 par value  Common  Stock  (the  "Common  Stock"),
issuable upon  conversion of  outstanding  6%  Convertible  Debentures  and upon
exercise  of  outstanding  Class I Warrants  and Class J Warrants  (collectively
referred  to as the  "Securities"),  which  are the  subject  of a  Registration
Statement on Form S-3 (the "Registration Statement") under the Securities Act of
1933,  as  amended.  We have acted as counsel for the  Company  with  respect to
certain matters in connection with the sale of the Securities and in preparation
of the required filings with the Securities and Exchange  Commission.  In giving
our opinion we have  assumed the Company  has  properly  reserved  the number of
authorized  and unissued  shares of Common Stock  required to be issued upon the
conversion of the outstanding 6% Convertible  Debentures  and/or exercise of the
Class I Warrants and Class J Warrants  and that as of the date of such  issuance
the  Company  continues  to exist.  Our  opinion is based  solely on the General
Corporation  Law of the State of Delaware.  In addition,  we have  examined such
documents  and  undertaken  such further  inquiry as we consider  necessary  for
rendering the opinions hereinafter set forth below:

         Based upon the  foregoing,  it is our opinion  that the upon receipt by
the  Company  of  the  consideration  provided  for  upon  conversion  of the 6%
Convertible  Debentures  and upon  exercise of the Class I Warrants  and Class J
Warrants,  respectively, the Common Stock, when issued in compliance with the 6%
Convertible Debentures and Class I Warrants and Class J Warrants,  respectively,
will be validly issued, fully paid and nonassessable.

         We  acknowledge  that we are  referred  to  under  the  heading  "Legal
Matters" in the Prospectus  which is part of the  Registration  Statement and we
hereby consent to the use of our name in such Registration Statement. We further
consent  to the  filing  of this  opinion  as  Exhibit  5.1 to the  Registration
Statement and with the state  regulatory  agencies in such states as may require
such filing in connection  with the  registration  of the Common Stock for offer
and sale in such states.

                                                             Respectfully yours,


                                                SQUIRE, SANDERS & DEMPSEY L.L.P.

                                                                    Exhibit 23.1


                    Consent of KPMG LLP, Independent Auditors



The Board of Directors
LightPath Technologies, Inc.


We consent to the use of our report  incorporated herein by reference and to the
reference to our firm under the heading "Experts" in the prospectus.

Our report dated August 10, 1999, contains an explanatory  paragraph that states
that the Company has suffered  recurring losses from operations and is dependent
on external sources of capital,  which raise substantial doubt about its ability
to continue as a going  concern.  The  financial  statements  do not include any
adjustments that might result from the outcome of that uncertainty.


                                                                        KPMG LLP
