                                       of
                          LIGHTPATH TECHNOLOGIES, INC.

         THIS CERTIFIES that  ________________  or any subsequent  holder hereof
("Holder"),  has the right to purchase  from  LIGHTPATH  TECHNOLOGIES,  INC.,  a
Delaware  corporation  (the  "Company"),  up to  _______________  fully paid and
nonassessable  shares of the Company's Class A common stock,  $.01 par value per
share ("Common  Stock"),  subject to adjustment as provided  herein,  at a price
equal to the Exercise Price as defined in Section 3 below, at any time beginning
on the Date of Issuance  (defined  below) and ending at 5:00 p.m., New York, New
York time, on September ___, 2000 (the "Exercise Period").

         Holder  agrees with the Company  that this  Warrant to Purchase  Common
Stock of LightPath Technologies,  Inc. (this "Warrant") is issued and all rights
hereunder  shall  be held  subject  to all of the  conditions,  limitations  and
provisions set forth herein.

         1.       Date of Issuance.
                  -----------------

         This Warrant  shall be deemed to be issued on October 2, 1997 ("Date of
Issuance").

         2.       Exercise.
                  ---------

         (a) Manner of Exercise. During the Exercise Period, this Warrant may be
exercised as to all or any lesser  number of full shares of Common Stock covered
hereby upon surrender of this Warrant, with the Exercise Form attached hereto as
Exhibit A (the "Exercise  Form") duly completed and executed,  together with the
full  Exercise  Price (as  defined  below) for each share of Common  Stock as to
which this  Warrant is  exercised,  at the office of the  Company,  6820 Academy
Parkway East NE, Albuquerque, New Mexico 87109; Attention:  President, Telephone
No. (505)  342-1100,  Telecopy No.  (505)  342-1111,  or at such other office or
agency as the Company may  designate  in writing,  by  overnight  mail,  with an
advance copy of the Exercise Form sent to the Company and
                                       1

its Transfer  Agent by  facsimile  (such  surrender  and payment of the Exercise
Price hereinafter called the "Exercise of this Warrant").

         (b) Date of Exercise.  The "Date of  Exercise" of the Warrant  shall be
defined as the date that the advance copy of the completed and executed Exercise
Form is sent by facsimile to the Company, provided that the original Warrant and
Exercise  Form are  received by the Company as soon as  practicable  thereafter.
Alternatively,  the Date of Exercise  shall be defined as the date the  original
Exercise Form is received by the Company,  if Holder has not sent advance notice
by facsimile.

         (c)  Cancellation  of Warrant.  This Warrant shall be canceled upon the
Exercise of this Warrant,  and, as soon as practical after the Date of Exercise,
Holder  shall be  entitled  to  receive  Common  Stock for the  number of shares
purchased  upon  such  Exercise  of this  Warrant,  and if this  Warrant  is not
exercised in full, Holder shall be entitled to receive a new Warrant (containing
terms identical to this Warrant)  representing  any unexercised  portion of this
Warrant in addition to such Common Stock.

         (d) Holder of Record.  Each person in whose name any Warrant for shares
of Common Stock is issued shall, for all purposes, be deemed to be the Holder of
record of such shares on the Date of Exercise of this Warrant,  irrespective  of
the date of delivery of the Common  Stock  purchased  upon the  Exercise of this
Warrant.  Nothing in this Warrant shall be construed as  conferring  upon Holder
any rights as a stockholder of the Company.

         3.       Payment of Warrant Exercise Price.
                  ----------------------------------

         The Exercise Price shall equal $7.2375 per share ("Exercise Price").

         Payment of the Exercise  Price may be made by either of the  following,
or a combination thereof, at the election of Holder:

         (i) Cash Exercise: cash, bank or cashiers check or wire transfer; or

         (ii) Cashless Exercise: subject to the last sentence of this Section 3,
surrender of this Warrant at the principal  office of the Company  together with
notice of cashless  election,  in which event the Company  shall issue  Holder a
number of shares of Common Stock computed using the following formula:

                           X = Y (A-B)/A

where:   X = the number of shares of Common Stock to be issued to Holder.

         Y         = the number of shares of Common Stock for which this Warrant
                   is being exercised.

                  A = the  Market  Price of one (1) share of Common  Stock  (for
                  purposes of this Section  3(ii),  the "Market  Price" shall be
                  defined as the average  closing bid price of the Common  Stock
                  for the five (5) trading days prior to the Date of Exercise of
                  this Warrant (the "Average Closing Price"), as reported by the
                  National Association of Securities Dealers Automated Quotation
                  System  ("Nasdaq") Small Cap Market, or if the Common Stock is
                  not traded on the Nasdaq Small Cap Market, the Average Closing
                  Price in any other over-the-counter market; provided, however,
                  that if the Common  Stock is listed on a stock  exchange,  the
                  Market  Price  shall  be the  Average  Closing  Price  on such
                  exchange  for the five (5)
                                       2

                  trading days prior to the date of exercise of the Warrants. If
                  the Common Stock is/was not traded during the five (5) trading
                  days prior to the Date of Exercise, then the closing price for
                  the last publicly traded day shall be deemed to be the closing
                  price for any and all (if  applicable)  days  during such five
                  (5) trading day period.

                  B = the Exercise Price.

For purposes of Rule 144 and  sub-section  (d)(3)(ii)  thereof,  it is intended,
understood and acknowledged that the Common Stock issuable upon exercise of this
Warrant in a cashless exercise transaction shall be deemed to have been acquired
at the time this Warrant was issued.  Moreover,  it is intended,  understood and
acknowledged that the holding period for the Common Stock issuable upon exercise
of this  Warrant  in a  cashless  exercise  transaction  shall be deemed to have
commenced on the date this Warrant was issued.

Notwithstanding  anything to the contrary contained herein, this Warrant may not
be exercised in a cashless exercise transaction if, on the Date of Exercise, the
shares of Common  Stock to be issued upon  exercise of this  Warrant  would upon
such issuance (x) be immediately  transferable  in the United States free of any
restrictive  legend,  including  without  limitation under Rule 144; (y) be then
registered  pursuant to an effective  registration  statement  filed pursuant to
that certain  Registration Rights Agreement dated on or about September __, 1997
by and among the Company and certain  investors;  or (z) otherwise be registered
under the Securities Act of 1933, as amended.

         4.       Transfer and Registration.
                  --------------------------

         (a) Transfer  Rights.  Subject to the  provisions  of Section 8 of this
Warrant,  this Warrant may be transferred on the books of the Company,  in whole
or in part, in person or by attorney,  upon  surrender of this Warrant  properly
completed and endorsed.  This Warrant shall be canceled upon such surrender and,
as soon as  practicable  thereafter,  the person to whom such  transfer  is made
shall be entitled to receive a new Warrant or Warrants as to the portion of this
Warrant transferred, and Holder shall be entitled to receive a new Warrant as to
the portion hereof retained.

         (b) Registrable Securities. The Common Stock issuable upon the exercise
of  this  Warrant  constitutes   "Registrable  Securities"  under  that  certain
Registration Rights Agreement dated on or about September ____, 1997 between the
Company  and  certain  investors  and,  accordingly,  has  the  benefit  of  the
registration rights pursuant to that agreement.

         5.       Anti-Dilution Adjustments.
                  --------------------------

         (a) Stock Dividend. If the Company shall at any time declare a dividend
payable in shares of Common  Stock,  then Holder,  upon Exercise of this Warrant
after the record date for the  determination of holders of Common Stock entitled
to receive such  dividend,  shall be entitled to receive  upon  Exercise of this
Warrant,  in addition  to the number of shares of Common  Stock as to which this
Warrant is  exercised,  such  additional  shares of Common  Stock as such Holder
would have received had this Warrant been  exercised  immediately  prior to such
record date and the Exercise Price will be proportionately adjusted.

         (b) Recapitalization or  Reclassification.  If the Company shall at any
time effect a recapitalization, reclassification or other similar transaction of
such  character  that the shares of Common Stock shall be changed into or become
exchangeable  for a larger or smaller number of shares,  then upon the effective
date  thereof,  the  number  of shares of Common  Stock  which  Holder  shall be
entitled to  purchase  upon  Exercise  of this  Warrant  shall be  increased  or
decreased,  as the case may be, in direct proportion to the increase or decrease
in the  number of shares  of  Common  Stock by reason of such  recapitalization,
reclassification or similar transaction, and the Exercise Price shall be, in the
case of an increase in the number of shares,  proportionally  decreased  and, in
                                       3

the case of  decrease  in the number of shares,  proportionally  increased.  The
Company shall give Holder the same notice it provides to holders of Common Stock
of any transaction described in this Section 5(b).

         (c)  Distributions.  If the Company shall at any time distribute for no
consideration  to holders of Common  Stock cash,  evidences of  indebtedness  or
other securities or assets (other than cash dividends or  distributions  payable
out of earned surplus or net profits for the current or preceding year) then, in
any such case,  Holder  shall be  entitled  to  receive,  upon  Exercise of this
Warrant, with respect to each share of Common Stock issuable upon such exercise,
the amount of cash or evidences of  indebtedness  or other  securities or assets
which Holder would have been entitled to receive with respect to each such share
of Common Stock as a result of the happening of such event had this Warrant been
exercised immediately prior to the record date or other date fixing shareholders
to be affected by such event (the "Determination  Date") or, in lieu thereof, if
the Board of  Directors  of the Company  should so determine at the time of such
distribution,  a reduced  Exercise Price  determined by multiplying the Exercise
Price on the  Determination  Date by a fraction,  the  numerator of which is the
result  of such  Exercise  Price  reduced  by the  value  of  such  distribution
applicable  to one share of Common  Stock  (such value to be  determined  by the
Board of  Directors of the Company in its  discretion)  and the  denominator  of
which is such Exercise Price.

         (d)  Notice  of  Consolidation  or  Merger.  In the  event of a merger,
consolidation,  exchange of shares, recapitalization,  reorganization,  or other
similar event, as a result of which shares of Common Stock shall be changed into
the same or a different number of shares of the same or another class or classes
of stock or securities or other assets of the Company or another entity or there
is a sale  of all or  substantially  all  the  Company's  assets  (a  "Corporate
Change"),  then this Warrant shall be  exerciseable  into such class and type of
securities  or other assets as Holder would have  received had Holder  exercised
this Warrant immediately prior to such Corporate Change; provided, however, that
Company  may not affect any  Corporate  Change  unless it first shall have given
thirty (30) days notice to Holder hereof of any Corporate Change.

         (e)  Exercise  Price  Adjusted.  As  used  in this  Warrant,  the  term
"Exercise  Price" shall mean the purchase price per share specified in Section 3
of this Warrant,  until the occurrence of an event stated in subsection (a), (b)
or (c) of this Section 5, and thereafter  shall mean said price as adjusted from
time to time in  accordance  with the  provisions  of said  subsection.  No such
adjustment  under this  Section 5 shall be made  unless  such  adjustment  would
change the Exercise Price at the time by $.01 or more; provided,  however,  that
all  adjustments  not so made  shall be  deferred  and made  when the  aggregate
thereof  would  change  the  Exercise  Price  at the  time by $.01 or  more.  No
adjustment  made  pursuant to any provision of this Section 5 shall have the net
effect of increasing  the Exercise  Price.  The number of shares of Common Stock
subject hereto shall increase proportionately with each decrease in the Exercise
Price.

         (f) Adjustments:  Additional Shares, Securities or Assets. In the event
that at any time, as a result of an adjustment  made pursuant to this Section 5,
Holder shall,  upon Exercise of this Warrant,  become entitled to receive shares
and/or other  securities  or assets  (other than Common  Stock)  then,  wherever
appropriate,  all references herein to shares of Common Stock shall be deemed to
refer to and  include  such  shares  and/or  other  securities  or  assets;  and
thereafter the number of such shares and/or other  securities or assets shall be
subject  to  adjustment  from time to time in a manner  and upon terms as nearly
equivalent as practicable to the provisions of this Section 5.

         6.       Fractional Interests.
                  ---------------------

                  No fractional shares or scrip  representing  fractional shares
shall be issuable  upon the  Exercise of this  Warrant,  but on Exercise of this
Warrant,  Holder may purchase only a whole number of shares of Common Stock. If,
on Exercise of this Warrant,  Holder would be entitled to a fractional  share of
Common  Stock or a 
                                       4

right to acquire a fractional share of Common Stock, such fractional share shall
be  disregarded  and the number of shares of Common Stock issuable upon exercise
shall be the next higher number of shares.

         7.       Reservation of Shares.
                  ----------------------

                  The  Company  shall at all times  reserve  for  issuance  such
number of authorized  and unissued  shares of Common Stock (or other  securities
substituted  therefor as herein above  provided) as shall be sufficient  for the
Exercise  of this  Warrant  and  payment  of the  Exercise  Price.  The  Company
covenants  and agrees  that upon the  Exercise  of this  Warrant,  all shares of
Common Stock issuable upon such exercise shall be duly and validly issued, fully
paid,  nonassessable  and not  subject  to  preemptive  rights,  rights of first
refusal or similar rights of any person or entity.

         8.       Restrictions on Transfer.
                  -------------------------

                  (a) Registration or Exemption Required.  This Warrant has been
issued in a transaction exempt from the registration  requirements of the Act by
virtue of Regulation D and exempt from state registration under applicable state
laws.  The  Warrant  and the Common  Stock  issuable  upon the  Exercise of this
Warrant may not be pledged,  transferred, sold or assigned except pursuant to an
effective   registration   statement  or  an   exemption  to  the   registration
requirements of the Act and applicable state laws.

                  (b)  Assignment.  If  Holder  can  provide  the  Company  with
reasonably  satisfactory  evidence that the  conditions  of (a) above  regarding
registration  or  exemption  have been  satisfied,  Holder  may sell,  transfer,
assign, pledge or otherwise dispose of this Warrant, in whole or in part. Holder
shall  deliver a written  notice to  Company,  substantially  in the form of the
Assignment  attached  hereto as Exhibit B,  indicating  the person or persons to
whom the Warrant shall be assigned and the  respective  number of warrants to be
assigned to each assignee.  The Company shall effect the  assignment  within ten
(10) days, and shall deliver to the  assignee(s)  designated by Holder a Warrant
or Warrants of like tenor and terms for the appropriate number of shares.

         9.       Benefits of this Warrant.
                  -------------------------

                  Nothing in this Warrant  shall be construed to confer upon any
person other than the Company and Holder any legal or equitable right, remedy or
claim under this  Warrant and this Warrant  shall be for the sole and  exclusive
benefit of the Company and Holder.

         10.      Applicable Law.
                  ---------------

                  This  Warrant is issued  under and shall for all  purposes  be
governed by and construed in accordance  with the laws of the state of Delaware,
without giving effect to conflict of law provisions thereof.

         11.      Loss of Warrant.
                  ----------------

                  Upon  receipt by the Company of  evidence of the loss,  theft,
destruction  or mutilation of this Warrant,  and (in the case of loss,  theft or
destruction)  of indemnity or security  reasonably  satisfactory to the Company,
and upon surrender and cancellation of this Warrant,  if mutilated,  the Company
shall execute and deliver a new Warrant of like tenor and date.

         12.      Notice or Demands.
                  ------------------

Notices or demands  pursuant to this Warrant to be given or made by Holder to or
