ITEM 5.  OTHER EVENTS.

                  1. On May 7, 1999 ("Closing  Date"),  several  purchasers (the
"Purchasers")  purchased an aggregate  1,500,000 shares of the Common Stock (the
"Shares") of Datametrics  Corporation (the  "Registrant") at a purchase price of
$1.00 per share,  pursuant to a Common Stock  Purchase  Agreement (the "Purchase
Agreement").  In connection with the sale of the Shares, the Purchasers received
warrants  ("Warrants")  to purchase up to an aggregate  1,500,000  shares of the
Registrant's  Common Stock for a per share  exercise  price of the lesser of (i)
$1.35; or (ii) the volume-weighted  average price of the Common Stock for the 20
trading  days  immediately  preceding  the notice of  exercise.  Under a related
Registration Rights Agreement,  the Registrant has agreed to file a Registration
Statement on Form SB-2 by June 1999 with respect to the Shares purchased and the
shares of Common  Stock which may be  acquired  upon  exercise  of the  Warrants
("Warrant Shares").  The Registrant expects to file a Registration  Statement on
Form SB-2  registering  its Common Stock for resale by the  Purchasers and other
selling shareholders.

                  The aggregate  cash  consideration  paid by the Purchasers was
$1,500,000, of which $250,000 was previously advanced to the Registrant pursuant
to a promissory  note  executed by the  Registrant,  dated April 27,  1999.  The
promissory note was canceled upon consummation of the Purchase Agreement.

                  The Purchase Agreement prohibits the Registrant, without prior
consent, from issuing any Common Stock or any financial instruments  convertible
into shares of Common Stock for a period of 120 days following the Closing Date,
and 30 days  following  the  effective  date of a  registration  statement  with
respect to the Shares and  Warrant  Shares.  In  addition,  the  Purchasers  are
prohibited from disposing of the Shares, Warrants or Warrant Shares for a period
of 60 days following the Closing Date.

                  The  Warrants  are  exercisable  immediately  and at any  time
during the 5-year period commencing with the Closing Date.  Twenty-Five  percent
of the Warrants are callable by the Registrant if its Common Stock has traded at
a price  equal to or greater  than $3.00 per share for the 20  consecutive  days
prior to the date of any call  notice,  provided  that the  Warrant  Shares  are
registered  at the time of the call.  The Warrants are subject to  adjustment in
certain circumstances to protect against antidilution.

                  The  Registrant  also  paid  a  fee  representing  5%  of  the
aggregate  purchase  price  in the  form of  Common  Stock  and  Warrants  to an
investment bank for brokerage and finding  services  rendered in connection with
the transaction.

                  Proceeds of the sale of the Shares and Warrants are to be used
for  working  capital  and payment of other  obligations  (including  payment of
$850,000 to The  Manufacturer's  Life Insurance  Company (U.S.A.)  pursuant to a
Mutual  Release  and  Settlement  Agreement  dated as of March 9,  1999).  It is
anticipated  that any proceeds  received by the Registrant  upon the exercise of
the Warrants will be used for working capital.

                  2.  Based  on  the  Company's  recent  financial  performance,
certain continued listing guidelines of the American Stock Exchange (the "AMEX")
are not currently met.  Accordingly,  there can be no assurance that the listing
of the  Company's  Common  Stock on the AMEX  will be  continued.  However,  the
Company  believes that the foregoing  sale of additional  equity will  favorably
influence the AMEX's evaluation of continued listing.

                  The above discussion is qualified in its entirety by reference
to the Common Stock Purchase  Agreement,  the Registration  Rights Agreement and
the Form of Warrant,  which are  substantially the same as Exhibits 4.1, 4.2 and
4.3 respectively, and are incorporated herein by this reference.

                         Representations and Warranties

         Section 3.1  REPRESENTATION AND WARRANTIES OF THE COMPANY . The Company
hereby makes the following representations and warranties to the Purchasers:

       (a)  ORGANIZATION,  GOOD STANDING AND POWER. The Company is a corporation
duly  incorporated,  validly existing and in good standing under the laws of the
State of  Delaware  and has the  requisite  corporate  power to own,  lease  and
operate its properties and assets and to conduct its business as it is now being
conducted.  The Company  does not have any  subsidiaries  (as defined in Section
3.1(g)).  The Company is duly qualified as a foreign  corporation to do business
and is in good  standing  in every  jurisdiction  in  which  the  nature  of the
business  conducted or property owned by it makes such  qualification  necessary
except for any  jurisdiction  in which the failure to be so  qualified  will not
have a material adverse effect on the Company's financial condition.

       (b) AUTHORIZATION;  ENFORCEMENT. The Company  has the requisite corporate
power  and  authority  to  enter  into  and  perform  this   Agreement  and  the
Registration  Rights  Agreement  in the form  attached  hereto as Exhibit B (the
"Registration  Rights  Agreement") and to issue and sell the Units in accordance
with the terms hereof. The execution, delivery and performance of this Agreement
and the Registration  Rights Agreement by the Company and the consummation by it
of the transactions  contemplated  hereby and thereby have been duly and validly
authorized  by all  necessary  corporate  action,  and  no  further  consent  or
authorization  of the  Company  or its Board of  Directors  or  stockholders  is
required.  Each of this Agreement and the Registration Rights Agreement has been
duly  executed  and  delivered by the Company.  Each of this  Agreement  and the
Registration Rights Agreement constitutes, or shall constitute when executed and
delivered, a valid and binding obligation of the Company enforceable against the
Company in  accordance  with its  terms,  except as such  enforceability  may be
limited  by  applicable  bankruptcy,  insolvency,  reorganization,   moratorium,
liquidation,  conservatorship,  receivership  or similar  laws  relating  to, or
affecting  generally the  enforcement of,  creditor's  rights and remedies or by
other equitable principles of general application.

         (c)  CAPITALIZATION.  The  authorized  capital stock of the Company and
the shares thereof issued and outstanding as of the date hereof are set forth on
Schedule 3.1(c) hereto.  All of the outstanding  shares of the Company's  Common
Stock have been duly and  validly  authorized.  Except as set forth on  Schedule
3.1(c), in this Agreement and the Registration Rights Agreement and as set forth
in the Prospectus  ("Description of Securities"),  no shares of Common Stock are
entitled  to  preemptive  rights  or  registration   rights  and  there  are  no
outstanding options,


                                        3

warrants,  scrip,  rights to subscribe to, call or  commitments of any character
whatsoever  relating to, or securities or rights convertible into, any shares of
capital stock of the Company. Furthermore, except as set forth in this Agreement
and the Registration Rights Agreement and as set forth on SCHEDULE 3.1(C) and in
the   Prospectus   ("Management"),   there   are  no   contracts,   commitments,
understandings,  or  arrangements by which the Company is or may become bound to
issue  additional  shares  of the  capital  stock  of the  Company  or  options,
securities  or rights  convertible  into shares of capital stock of the Company.
Except for customary transfer restrictions  contained in agreements entered into
by the Company in order to sell restricted  securities,  as provided on SCHEDULE
3.1(C) or disclosed in the  Prospectus  ("Risk  Factors"),  the Company is not a
party to any agreement  granting  registration  or  anti-dilution  rights to any
person  with  respect  to any of its  equity or debt  securities  other than the
Selling  Shareholders in the  Prospectus.  The Company is not a party to, and it
has no knowledge  of, any  agreement  restricting  the voting or transfer of any
shares of the capital  stock of the  Company.  The offer and sale of all capital
stock,  convertible  securities,  rights,  warrants,  or options of the  Company
issued  prior to the  Closing  complied  with all  applicable  Federal and state
securities  laws, and no  stockholder  has a right of rescission or damages with
respect  thereto  which would have a Material  Adverse  Effect.  The Company has
furnished or made  available to the  Purchasers  true and correct  copies of the
Company's  Certificate  of  Incorporation  as in effect on the date  hereof (the
"Articles"),  and the  Company's  Bylaws as in effect  on the date  hereof  (the
"Bylaws").

         (d)  ISSUANCE  OF UNITS.  The Units to be issued  under this  Agreement
have been duly authorized by all necessary corporate action and, when issued and
paid for in accordance with the terms hereof,  the Units shall be validly issued
and  outstanding,  fully  paid and  nonassessable,  free and clear of all liens,
encumbrances,  and rights of first refusal of any kind.  When the Warrant Shares
are issued in  accordance  with the terms of the  Warrants,  such shares will be
duly  authorized  by all  necessary  corporate  action  and  validly  issued and
outstanding, fully paid and nonassessable,  and the Purchasers shall be entitled
to all rights accorded to a holder of Common Stock. At least 1,875,000 shares of
Common Stock have been duly  authorized  and reserved for issuance upon exercise
of the Warrants.

         (e) NO  CONFLICTS. The  execution,  delivery  and  performance  of this
Agreement  and  the  Registration  Rights  Agreement  by  the  Company  and  the
consummation by the Company of the transactions  contemplated herein and therein
do not (i) violate  any  provision  of the  Company's  Articles or Bylaws,  (ii)
conflict  with,  or constitute a default (or an event which with notice or lapse
of time or both would become a default)  under,  or give to others any rights of
termination, amendment, acceleration or cancellation of, any material agreement,
mortgage,  deed of trust,  indenture,  note,  bond,  license,  lease  agreement,
instrument or obligation to which the Company is a party, (iii) create or impose
a lien, charge or encumbrance on any property of the Company under any agreement
or any commitment to which the Company is a party or by which


                                        4

<PAGE>


the Company is bound or by which any of its respective  properties or assets are
bound,  or (iv) result in a violation  of any federal,  state,  local or foreign
statute,  rule,  regulation,  order,  judgment or decree (including  Federal and
state securities laws and  regulations)  applicable to the Company or any of its
subsidiaries  or by which any  property  or asset of the  Company  or any of its
subsidiaries are bound or affected, except for (in the case of subsections (ii),
(iii) and (iv),  above),  such conflicts,  defaults,  terminations,  amendments,
acceleration,  cancellations and violations as would not, individually or in the
aggregate,  have a Material  Adverse  Effect.  The Company is not required under
Federal,  state  or  local  law,  rule or  regulation  to  obtain  any  consent,
authorization or order of, or make any filing or registration with, any court or
governmental  agency in order for it to  execute,  deliver or perform any of its
obligations under this Agreement and the Registration Rights Agreement, or issue
and sell the Units, Common Stock,  Warrants and the Warrant Shares in accordance
with the terms hereof  (other than any filings  which may be required to be made
by the Company with the Securities and Exchange  Commission (the  "Commission"),
the American Stock Exchange,  or state securities  administrators  subsequent to
the  Closing,  and,  any  registration  statement  which  may be filed  pursuant
hereto);  provided  that,  for  purposes  of the  representation  made  in  this
sentence,  the Company is assuming and relying upon the accuracy of the relevant
representations and agreements of each of the Purchasers herein.

         (f) COMMISSION DOCUMENTS, FINANCIAL STATEMENTS. The Common Stock of the
Company is  registered  pursuant to Section  12(b) or 12(g) of the Exchange Act,
and, the Company has timely filed all reports,  schedules, forms, statements and
other documents  required to be filed by it with the Commission  pursuant to the

complete  copies of the Commission  Documents  filed with the  Commission  since

the Purchasers any material  non-public  information  relating to the Company or
information which, according to applicable law, rule or regulation,  should have
been  disclosed  publicly by the  Company  but which has not been so  disclosed,
other than with respect to the transactions contemplated by this Agreement or as
set forth in the Prospectus. As of their respective dates, the Form 10-K for the

Exchange  Act  and the  rules  and  regulations  of the  Commission  promulgated
thereunder  and  other  federal,  state and local  laws,  rules and  regulations
applicable to such documents,  and, as of their  respective  dates,  none of the
Form 10-K and the Form 10-Q referred to above contained any untrue  statement of
a  material  fact or  omitted to state a  material  fact  required  to be stated
therein or necessary in order to make the  statements  therein,  in light of the
circumstances under which they were made, not misleading. The financial


                                        5

<PAGE>

statements of the Company included in the Commission Documents comply as to form
in all  material  respects  with  applicable  accounting  requirements  and  the
published rules and regulations of the Commission or other  applicable rules and
regulations with respect thereto.  Such financial  statements have been prepared
in accordance with generally accepted accounting  principles ("GAAP") applied on
a consistent  basis during the periods  involved (except (i) as may be otherwise
indicated in such financial  statements or the notes thereto or (ii) in the case
of unaudited interim statements, to the extent they may not include footnotes or
may be  condensed  or summary  statements),  and fairly  present in all material
respects the  financial  position of the Company as of the dates thereof and the
results of operations and cash flows for the periods then ended (subject, in the
case of unaudited statements, to normal year-end audit adjustments).

this Agreement, "subsidiary" shall mean any corporation or other entity of which

or other persons  performing similar functions are at the time owned directly or
indirectly by the Company and/or any of its other subsidiaries.

         (h) NO  MATERIAL  ADVERSE  CHANGE.  Since  January 24,  1999,  the date
through which the most recent  quarterly  report of the Company on Form 10-Q has
been prepared and filed with the Commission,  a copy of which is included in the
Commission  Documents,   and  except  as  disclosed  in  the  Prospectus  ("Risk
Factors"),  the Company has not  experienced  or suffered any  Material  Adverse
Effect.

         (i) NO UNDISCLOSED  LIABILITIES.  Except as disclosed in the Prospectus
("Risk Factors"), the Company has no liabilities,  obligations, claims or losses
(whether liquidated or unliquidated,  secured or unsecured,  absolute,  accrued,
contingent or otherwise),  other than those  incurred in the ordinary  course of
the Company's business since January 24, 1999 and which,  individually or in the
aggregate, do not or could not be reasonably expected to have a Material Adverse
Effect.

         (j) NO UNDISCLOSED  EVENTS OR  CIRCUMSTANCES.  No event or circumstance
has occurred or exists with respect to the Company or its business,  properties,
prospects,  operations or financial condition, which, under applicable law, rule
or regulation,  requires  public  disclosure or  announcement by the Company but
which has not been so publicly announced or disclosed.

         (k)  INDEBTEDNESS.  SCHEDULE  3.1(K)  hereto  sets forth as of the date

which  the  Company  has  commitments.  For  the  purposes  of  this  Agreement,
"Indebtedness" shall mean (a) any liabilities for borrowed money or amounts owed
in excess of $25,000 (other than trade accounts payable


                                        6

<PAGE>

incurred in the ordinary course of business consistent with past practices), (b)
all  guaranties,  endorsements  and other  contingent  obligations in respect of
Indebtedness  of others,  whether or not the same are or should be  reflected in
the  Company's  balance  sheet  (or the notes  thereto),  except  guaranties  by
endorsement  of  negotiable  instruments  for deposit or  collection  or similar
transactions  in the ordinary  course of business;  and (c) the present value of
any lease  payments  in excess  of  $25,000  due  under  leases  required  to be
capitalized in accordance  with GAAP. The Company is not in default with respect
to any Indebtedness.

         (l) TITLE TO ASSETS.  The Company has good and marketable  title to all
of its real and personal property reflected in the Commission Documents, free of
any  mortgages,   pledges,   charges,   liens,   security   interests  or  other
encumbrances,  except for liens  securing  indebtedness  listed in Note 7 to the
Financial  Statements  contained  in the  Prospectus  or  such  that  could  not
reasonably be expected to cause a Material  Adverse  Effect.  All said leases of
the Company are valid and subsisting and in full force and effect.

         (m) ACTIONS PENDING.  There is no action, suit, claim, investigation or
proceeding  pending or, to the knowledge of the Company,  threatened against the
Company or any subsidiary  which questions the validity of this Agreement or the
transactions  contemplated  hereby or any action  taken or to be taken  pursuant
hereto or thereto. Except as set forth in the Prospectus ("Risk Factors"), there
is no action,  suit,  claim,  investigation  or  proceeding  pending  or, to the
knowledge of the Company, threatened, against or involving the Company or any of
its  properties  or  assets.   There  are  no  outstanding  orders,   judgments,
injunctions,  awards or decrees  of any court,  arbitrator  or  governmental  or
regulatory  body against the Company or any officers or directors of the Company
in their capacities as such.

         (n)  COMPLIANCE  WITH LAW.  The business of the Company has been and is
presently being conducted in accordance with all applicable  federal,  state and
local  governmental  laws,  rules,  regulations  and  ordinances  or such  that,
individually  or in the  aggregate,  could not reasonably be expected to cause a
Material  Adverse  Effect.  The Company has all franchises,  permits,  licenses,
consents and other  governmental  or  regulatory  authorizations  and  approvals
necessary  for the conduct of its  business as now being  conducted by it unless
the failure to possess such franchises,  permits,  licenses,  consents and other
governmental or regulatory authorizations and approvals,  individually or in the
aggregate, could not reasonably be expected to have a Material Adverse Effect.

         (o) TAXES . Except as set forth on SCHEDULE 3.1(O) hereto,  the Company
has  accurately  prepared  and filed all  federal,  state and other tax  returns
required by law to be filed by it, has paid or made  provisions  for the payment

Schedule  3.1(o)  hereto,  none of the federal income tax returns of the Company
for the years  subsequent  to October 21, 1995 have been audited by the Internal
Revenue  Service.  The Company has no knowledge of any  additional  assessments,

threatened  against the  Company  for any period,  nor of any basis for any such
assessment, adjustment or contingency.

         (p) CERTAIN FEES.  Except as set forth on Schedule  3.1(p)  hereto,  no
brokers,  finders or financial  advisory fees or commissions  will be payable by
the Company or any Purchaser with respect to the  transactions  contemplated  by
this Agreement.

         (q) DISCLOSURE.  To the best of the Company's  knowledge,  neither this
Agreement (including the Schedules hereto) nor any other documents, certificates
or  instruments  furnished to the  Purchasers  by or on behalf of the Company in
connection  with the  transactions  contemplated  by this Agreement  contain any
untrue  statement of a material fact or omit to state a material fact  necessary
in order to make the  statements  made  herein or  therein,  in the light of the
circumstances under which they were made herein or therein, not misleading.

         (r)  OPERATION OF BUSINESS. The Company owns or possesses all patents,
trademarks, service marks, trade names, copyrights,  licenses and authorizations
as set forth in the Prospectus  ("Intellectual  Property"),  and all rights with
respect to the foregoing, which are necessary for the conduct of its business as
now  conducted  without any  conflict  with the rights of others,  except to the
extent that a Material Adverse Effect could not reasonably be expected to result
from such conflict.

         (s)  ENVIRONMENTAL  COMPLIANCE.  The Company  has obtained all material
approvals, authorization,  certificates,  consents, licenses, orders and permits
or other similar  authorizations  of all governmental  authorities,  or from any
other person,  that are required under any  Environmental  Laws.  "Environmental
Laws"  shall  mean  all  applicable  laws  relating  to  the  protection  of the
environment  including,  without  limitation,  all  requirements  pertaining  to
reporting,  licensing,  permitting,  controlling,  investigating  or remediating
emissions,  discharges, releases or threatened releases of hazardous substances,
chemical substances, pollutants,  contaminants or toxic substances, materials or
wastes, whether solid, liquid or gaseous in nature, into the air, surface water,
groundwater or land, or relating to the manufacture,  processing,  distribution,
use,  treatment,   storage,   disposal,   transport  or  handling  of  hazardous
substances, chemical substances,  pollutants,  contaminants or toxic substances,
material or wastes,  whether solid, liquid or gaseous in nature. The Company has
all necessary  governmental  approvals required under all Environmental Laws and
used in its business. The Company is also in



                                        8

<PAGE>



compliance  with all other  limitations,  restrictions,  conditions,  standards,
requirements,   schedules   and   timetables   required  or  imposed  under  all
Environmental  Laws.  Except for such instances as would not  individually or in
the  aggregate  have a  Material  Adverse  Effect,  there are no past or present
events, conditions,  circumstances,  incidents, actions or omissions relating to
or in any way affecting the Company that violate or could reasonably be expected
to violate any  Environmental  Law after the Closing or that could reasonably be
expected to give rise to any  environmental  liability,  or  otherwise  form the
basis  of any  claim,  action,  demand,  suit,  proceeding,  hearing,  study  or
investigation  (i) under any  Environmental  Law, or (ii) based on or related to
the presence,  manufacture,  processing,  distribution,  use, treatment, storage
(including without limitation underground storage tanks), disposal, transport or
handling,  or the  emission,  discharge,  release or  threatened  release of any
hazardous substance.

         (T) BOOKS AND RECORD:  INTERNAL  ACCOUNTING  CONTROLS.  The records and
documents  of the  Company,  accurately  reflect in all  material  respects  the
information  relating to the business of the Company the location and collection
of its assets and the nature of all transactions  giving rise to the obligations
or  accounts  receivable  of the  Company.  The  Company  maintains  a system of
internal accounting controls sufficient,  in the judgment of the Company's board
of directors, to provide reasonable assurance that (i) transactions are executed
in  accordance  with  management's  general  or  specific  authorizations,  (ii)
transactions  are  recorded as  necessary  to permit  preparation  of  financial
statements in conformity with generally  accepted  accounting  principles and to
maintain  asset  accountability,  (iii)  access to assets is  permitted  only in
accordance  with  management's  general or specific  authorization  and (iv) the
recorded  accountability  for assets is  compared  with the  existing  assets at
reasonable  intervals  and  appropriate  actions  is taken  with  respect to any
differences.

         (u) MATERIAL  AGREEMENTS.  The Company is not a party to any written or
oral  contract,   instrument,   agreement,   commitment,   obligation,  plan  or
arrangement,  a copy of which would be required to be filed with the  Commission
as an  exhibit  to a  registration  statement  on Form SB-2 or  applicable  form
(collectively, "Material Agreements") if the Company were registering securities
under the Securities Act. The Company has in all material respects performed all
the  obligations  required  to be  performed  by it to date under the  foregoing
agreements,  has received no notice of default and, to the best of the Company's
knowledge is not in default  under any  Material  Agreement  now in effect,  the
result of which could reasonably be expected to cause a Material Adverse Effect.

         (v) TRANSACTIONS WITH AFFILIATES.  Except for the purchase by Daniel P.
Ginns of  $150,000  of bridge  notes,  there are no loans,  leases,  agreements,
contracts,  royalty  agreements,  management  contracts or arrangements or other
continuing transactions exceeding $100,000 between (a) the Company or any of its
respective customers or suppliers on the one hand, and (b)


                                        9

<PAGE>

on the other hand, any officer, employee,  consultant or director of the Company
or any  person  who would be covered  by Item  404(a) of  Regulation  S-K or any
corporation or other entity  controlled by such officer,  employee,  consultant,
director or person.

         (w)  SECURITIES  ACT OF 1933.  The Company has complied and will comply
with all applicable  Federal and state  securities  laws in connection  with the
offer,  issuance and sale of the Units and other securities  hereunder.  Neither
the Company nor anyone acting on its behalf, directly or indirectly, has or will
sell, offer to sell or solicit offers to buy the Units or similar securities to,
or solicit  offers with  respect  thereto  from,  or enter into any  preliminary
conversations or negotiations  relating thereto with, any person, so as to bring

Securities Act and applicable state securities laws. Neither the Company nor any
of its affiliates,  nor any person acting on its or their behalf, has engaged in
any form of general  solicitation or general  advertising (within the meaning of
Regulation D under the Securities  Act) in connection  with the offer or sale of
the Units and other securities hereunder.

         (x) EMPLOYEES.  The Company has no collective  bargaining  arrangements
or  agreements  covering  any of its  employees.  Except  as  set  forth  in the
Prospectus  ("Employment  Contract") or as otherwise disclosed in writing by the
Company to the  Purchasers,  the Company has no employment  contract,  agreement
regarding proprietary  information,  noncompetition  agreement,  nonsolicitation
agreement,   confidentiality   agreement,  or  any  other  similar  contract  or
restrictive  covenant,  relating  to the  right  of  any  officer,  employee  or
consultant  to be employed or engaged by the Company or obtain any rights in any
assets of the Company.  Since  October 24, 1998,  no officer,  consultant or key
employee  of  the  Company  whose  termination,  either  individually  or in the
aggregate,  could reasonably be expected to have a Material Adverse Effect,  has
terminated  or, to the  knowledge of the Company,  has any present  intention of
terminating his or her employment or engagement with the Company.

         (y)  ABSENCE OF CERTAIN  DEVELOPMENTS.  Except as  provided on Schedule
3.1(y) hereto or disclosed in the Prospectus ("Risk Factors"), since October 24,
1998, the Company has not:

comparable  portion of its prior fiscal year, as adjusted to reflect the current
nature and volume of the Company's business;


                                       10

         (aa) PUBLIC  UTILITY  HOLDING  COMPANY ACT AND  INVESTMENT  COMPANY ACT
STATUS.  The Company is not a "holding company" or a "public utility company" as
such terms are defined in the Public  Utility  Holding  Company Act of 1935,  as
amended.  The Company is not,  and as a result of and  immediately  upon Closing
will not be, an "investment company" or a company "controlled" by an "investment
company," within the meaning of the Investment Company Act of 1940, as amended.

         (bb) ERISA.  No liability to the Pension Benefit  Guaranty  Corporation
has been incurred with respect to any Plan by the Company which has had or could
reasonably  be expected to have a Material  Adverse  Effect on the Company.  The
execution  and  delivery of this  Agreement  and the issue and sale of the Units
will not involve any transaction which is subject to the prohibitions of Section
406 of ERISA or in  connection  with  which a tax could be imposed  pursuant  to
Section 4975 of the Internal Revenue Code of 1986, as amended, provided that, if
any of the Purchasers,  or any person or entity that owns a beneficial  interest
in any of the  Purchasers,  is an "employee  pension  benefit  plan" (within the
meaning of Section  3(2) of ERISA) with respect to which the Company is a "party
in interest" (within the meaning of Section 3(14) of ERISA), the requirements of
Sections 407(d)(5) and 408(e) of ERISA, if applicable,  are met. As used in this
Section 2.1(ac),  the term "Plan" shall mean an "employee  pension benefit plan"
(as  defined  in  Section  3 of  ERISA)  which  is or has  been  established  or
maintained,  or to which  contributions are or have been made, by the Company or
by any trade or business, whether or not incorporated,  which, together with the
Company,  is under common control,  as described in Section 414(b) or (c) of the
Code.

         (cc)  ACKNOWLEDGMENT  REGARDING  PURCHASER'S  PURCHASE  OF  UNITS.  The
Company   acknowledges  and  agrees  that  each  of  the  Purchasers  is  acting
individually  and solely in the capacity of arm's length  purchaser with respect
to this  Agreement,  the  Registration  Rights  Agreement  and the  transactions
contemplated  hereunder and thereunder.  The Company further  acknowledges  that
each of the Purchasers is not acting as a financial  advisor or fiduciary of the
Company  (or in any  similar  capacity)  with  respect  to this  Agreement,  the
Registration  Rights Agreement and the transactions  contemplated  hereunder and
thereunder  and  any  advice  given  by any of the  Purchasers  or any of  their
representatives  or agents in connection with this Agreement,  the  Registration
Rights Agreement and the transactions


                                       12

<PAGE>


contemplated  hereunder and thereunder is merely  incidental to such Purchaser's
purchase of the Units.

         (dd) DILUTIVE EFFECT. The Company understands and acknowledges that the
number of Warrant Shares issuable upon exercise of the Warrants will increase in
certain  circumstances.  The Company further acknowledges that its obligation to
issue the Warrant  Shares upon the exercise of the Warrants in  accordance  with
this Agreement and the Warrants,  is, in each case,  absolute and  unconditional
regardless  of the dilutive  effect that such issuance may have on the ownership
interest of other stockholders of the Company.

         Section 3.2  REPRESENTATIONS  AND  WARRANTIES  OF THE  PURCHASERS.  The
Purchasers  hereby severally and not jointly make the following  representations
and warranties to the Company:

         (a)  ORGANIZATION  AND STANDING OF THE PURCHASERS.  Such Purchaser is a
corporation duly  incorporated (in the case of a corporate  Purchaser),  validly
existing  and in  good  standing  under  the  laws  of the  jurisdiction  of its
incorporation.

         (b)  AUTHORIZATION  AND POWER.  Such Purchaser has the requisite  power
and authority to enter into and perform this Agreement and to purchase the Units
being sold to it hereunder.  The  execution,  delivery and  performance  of this
Agreement  and the  Registration  Rights  Agreement  by such  Purchaser  and the
consummation  by it of the  transactions  contemplated  hereby  have  been  duly
authorized by all necessary action.  Each of this Agreement and the Registration
Rights Agreement constitutes, or shall constitute when executed and delivered, a
valid  and  binding  obligation  of  such  Purchaser  enforceable  against  such
Purchaser in accordance  with its terms,  except as such  enforceability  may be
limited  by  applicable  bankruptcy,  insolvency,  reorganization,   moratorium,
liquidation,  conservatorship,  receivership,  or similar  laws  relating to, or
affecting  generally the  enforcement of,  creditor's  rights and remedies or by
other equitable principles of general application.

         (c) NO  CONFLICTS.  The  execution,  delivery and  performance  of this
Agreement and the  Registration  Rights  Agreement and the  consummation by such
Purchaser of the transactions contemplated hereby and thereby or relating hereto
do not and  will not (i)  result  in a  violation  of such  Purchaser's  charter
documents or bylaws or (ii) conflict  with, or constitute a default (or an event
which with  notice or lapse of time or both would  become a default)  under,  or
give  to  others  any  rights  of   termination,   amendment,   acceleration  or
cancellation  of any agreement,  indenture or instrument to which such Purchaser
is a party,  or result in a violation of any law,  rule, or  regulation,  or any
order, judgment or decree of any court or governmental agency applicable to such
Purchaser or its properties,  except for such conflicts, defaults and violations
as would not, individually or in the aggregate,  prohibit or otherwise interfere
with the ability of such Purchaser


                                       13

<PAGE>

to enter into and perform its  obligations  under this Agreement in any material
respect. Such Purchaser is not required to obtain any consent,  authorization or
order of, or make any filing or  registration  with,  any court or  governmental
agency in order for it to  execute,  deliver or perform  any of its  obligations
under this  Agreement or the  Registration  Rights  Agreement or to purchase the
Units in  accordance  with the terms  hereof,  provided that for purposes of the
representation  made in this  sentence,  such  Purchaser is assuming and relying
upon the accuracy of the relevant  representations and agreements of the Company
herein.

         (d) ACQUISITION FOR INVESTMENT.  Such Purchaser is purchasing the Units
solely for its own account for the purpose of  investment.  Such  Purchaser does
not have a present arrangement or intention to effect any organized distribution
of the Units or the Common  Stock to or through  any person or entity and agrees
not to sell,  assign or otherwise  transfer  any of its shares of Common  Stock,
Warrants  or Warrant  Shares for a period of sixty (60) days  commencing  on the
Closing  Date (the  "Lock-Up  Period");  provided,  however,  that by making the
representations  herein,  such  Purchaser  reserves  the right to dispose of the
Common  Stock,  the  Warrants or the Warrant  Shares at any time  following  the
Lock-Up Period in accordance  with Federal and state  securities laws applicable
to such  disposition.  Such Purchaser  acknowledges  that it is able to bear the
financial risks  associated with an investment in the Units and that it has been
given full access to such records of the Company and the subsidiaries and to the
officers of the  Company  and the  subsidiaries  as it has deemed  necessary  or
appropriate  to conduct  its due  diligence  investigation.  Such  Purchaser  is
capable  of  evaluating  the risks and merits of an  investment  in the Units by
virtue of its  experience  as an investor  and its  knowledge,  experience,  and
sophistication  in financial and business  matters and such Purchaser is capable
of bearing the entire loss of its investment in the Units.

         (e) ACCREDITED  PURCHASERS.  Such Purchaser is an "accredited investor"
as defined in Regulation D promulgated under the Securities Act.

         (f)  INFORMATION.  Such  Purchaser and its advisors,  if any, have been
furnished with all materials  relating to the business,  finances and operations
of the Company and  materials  relating to the offer and sale of the Units which
have been requested by such Purchaser . Such Purchaser and its advisors, if any,
have been  afforded  the  opportunity  to ask  questions  of the  Company.  Such
Purchaser has sought such accounting,  legal and tax advice as it has considered
necessary  to  make  an  informed   investment  decision  with  respect  to  its
acquisition  of the  Units.  Such  Purchaser  understands  that it (and  not the
Company) shall be responsible  for its own tax  liabilities  that may arise as a
result of this investment or the transactions contemplated by this Agreement.



                                       14

<PAGE>



         (g)  General  . Such  Purchaser  understands  that the  Units are being
offered and sold in reliance on a transactional  exemption from the registration
requirement of Federal and state securities laws and the Company is relying upon
the  truth  and  accuracy  of  the  representations,   warranties,   agreements,
acknowledgments  and  understandings of such Purchaser set forth herein in order
to determine the  applicability  of such  exemptions and the suitability of such
Purchaser to acquire the Units.

                                   TERMINATION

         Section  6.1  TERMINATION  BY  MUTUAL  CONSENT.  This  Agreement  shall
terminate  on May 10,  1999 if the Units  have not been  issued  and sold by the
Company and  purchased by the  Purchasers.  This  Agreement may be terminated by
mutual consent of the parties.

         Section 6.2  OTHER  TERMINATION.  The  Purchasers  may  terminate  this
Agreement if (x) an event  resulting in a Material  Adverse Effect has occurred,
or,  (y) the  Company  is  insolvent  or has  commenced  or is the  subject of a

Article VII herein.  Nothing in this  Section 6.3 shall be deemed to release the
Company  or the  Purchasers  from  any  liability  for  any  breach  under  this
Agreement,  or to impair the rights of the Company and the  Purchasers to compel
specific performance by the other party of its obligations under this Agreement.

                                   ARTICLE VII

                                 INDEMNIFICATION

         Section 7.1  GENERAL INDEMNITY.  The Company  agrees to  indemnify  and
hold harmless each Purchaser (and its directors,  officers,  affiliates, agents,
successors and assigns but excluding consequential damages) from and against any
and all actual losses, liabilities,  deficiencies, costs, damages and reasonable
expenses (including, without limitation, reasonable attorney's fees, charges and
disbursements)  incurred  by such  Purchaser  as a result  of any  breach of the
covenants  made by the  Company  herein.  Each  Purchaser  severally  agrees  to
indemnify and hold harmless the Company and its directors, officers, affiliates,
agents,  successors  and assigns  from and  against  any and all actual  losses,
liabilities,  deficiencies,  costs,  damages and  expenses  (including,  without
limitation,  reasonable  attorneys fees, charges and disbursements but excluding
consequential  damages)  incurred  by the Company as result of any breach of the
covenants made by such Purchaser herein.

         Section  7.2   INDEMNIFICATION   PROCEDURE.   Any   party  entitled  to
indemnification  under  this  Article  VII (an  "indemnified  party")  will give
written notice to the  indemnifying  party of any matters giving rise to a claim
for  indemnification;  provided,  that the  failure  of any  party  entitled  to
indemnification  hereunder  to give notice as provided  herein shall not relieve
the indemnifying  party of its obligations  under this Article VII except to the
extent that the  indemnifying  party is actually  prejudiced  by such failure to
give  notice.  In case any  action,  proceeding  or claim is brought  against an
indemnified party in respect of which  indemnification is sought hereunder,  the
indemnifying  party  shall be  entitled  to  participate  in and,  unless in the
reasonable  judgment of the indemnified  party a conflict of interest between it
and the indemnifying party may exist with respect of such action,  proceeding or
claim, to assume the defense thereof with counsel reasonably satisfactory to the
indemnified  party.  In  the  event  that  the  indemnifying  party  advises  an
indemnified  party  that  it  will  contest  such a  claim  for  indemnification
hereunder,  or fails,  within thirty (30) days of receipt of any indemnification
notice to notify, in writing,  such person of its election to defend,  settle or
compromise,  at its sole cost and expense,  any action,  proceeding or claim (or
discontinues its defense at any time after it commences such defense),  then the
indemnified party may, at its option,  defend, settle or otherwise compromise or
pay such action or claim. In any event,  unless and until the indemnifying party
elects in writing to assume  and does so assume the  defense of any such  claim,
proceeding or action, the indemnified  party's costs and expenses arising out of
the defense,  settlement or  compromise of any such action,  claim or proceeding
shall be losses subject to  indemnification  hereunder.  The  indemnified  party
shall  cooperate  fully  with  the  indemnifying  party in  connection  with any
negotiation or defense of any such action or claim by the indemnifying party and
shall furnish to the indemnifying party


                                       21

<PAGE>


all information  reasonably  available to the indemnified party which relates to
such action or claim.  The indemnifying  party shall keep the indemnified  party
fully  apprised at all times as to the status of the  defense or any  settlement
negotiations  with respect thereto.  If the indemnifying  party elects to defend
any such  action or claim,  then the  indemnified  party  shall be  entitled  to
participate  in such  defense  with  counsel  of its choice at its sole cost and
expense.  The  indemnifying  party shall not be liable for any settlement of any
action,  claim  or  proceeding  effected  without  its  prior  written  consent.
Notwithstanding  anything in this Article VII to the contrary,  the indemnifying
party shall not,  without the  indemnified  party's prior written consent (which
consent shall not be unreasonable  withheld),  settle or compromise any claim or
consent to entry of any  judgment in respect  thereof  which  imposes any future
obligation  on  the  indemnified  party  or  which  does  not  include,   as  an
unconditional  term thereof,  the giving by the claimant or the plaintiff to the
indemnified  party of a release from all liability in respect of such claim. The
indemnification  required by this Article VII shall be made by periodic payments
of the amount thereof during the course of investigation or defense, as and when
bills are received or expense, loss, damage or liability is incurred, so long as
the  indemnified  party  irrevocably  agrees  to  refund  such  moneys  if it is
ultimately  determined by a court of competent  jurisdiction that such party was
not entitled to indemnification. The indemnity agreements contained herein shall
be in addition to (a) any cause of action or similar  rights of the  indemnified
party against the  indemnifying  party or others,  and (b) any  liabilities  the
indemnifying party may be subject to pursuant to the law.

                                  MISCELLANEOUS

         Section 8.1 FEES AND  EXPENSES.  The Company  shall pay all  reasonable
fees and expenses  related to the  transactions  contemplated by this Agreement;
provided,  that the Company shall pay, at the Closing,  all reasonable attorneys
fees and  expenses  (exclusive  of  disbursements  and  out-of-pocket  expenses)
incurred by the Purchasers in an amount not to exceed $10,000 in connection with
the  preparation,  negotiation,  execution  and delivery of this  Agreement.  In
addition, the Company shall pay all reasonable fees and expenses incurred by the
Purchasers in connection with any amendments,  modifications  or waivers of this
Agreement or the  Registration  Rights  Agreement or incurred in connection with
the  enforcement  of this  Agreement  and  the  Registration  Rights  Agreement,
including,  without limitation,  all reasonable attorneys fees and expenses. The
Company  shall  pay all  stamp or other  similar  taxes  and  duties  levied  in
connection with issuance of the Units pursuant hereto.

         Section 8.2  SPECIFIC ENFORCEMENT, CONSENT TO JURISDICTION .

         (a)  The  Company  and  each  Purchaser   acknowledge  and  agree  that
irreparable  damage would occur in the event that any of the  provisions of this
Agreement or the Registration  Rights Agreement were not performed in accordance
with their specific terms or were otherwise  breached.  It is accordingly agreed
that the parties shall be entitled to an injunction or injunctions to prevent or
cure breaches of the  provisions of this  Agreement or the  Registration  Rights
Agreement  and to  enforce  specifically  the  terms  and  provisions  hereof or
thereof,  this being in addition to any other remedy to which any of them may be
entitled by law or equity.

         (b) Each of the  Company  and each  Purchaser  (i)  hereby  irrevocably
submits to the jurisdiction of the United States District Court and other courts
of the  United  States  sitting  in the  Southern  District  of New York for the
purposes of any suit,  action or  proceeding  arising out of or relating to this
Agreement or the  Registration  Rights  Agreement  and (ii) hereby  waives,  and
agrees not to assert in any such suit,  action or proceeding,  any claim that it
is not  personally  subject to the  jurisdiction  of such court,  that the suit,
action or  proceeding is brought in an  inconvenient  forum or that the venue of
the  suit,  action or  proceeding  is  improper.  Each of the  Company  and each
Purchaser  consents  to  process  being  served  in any  such  suit,  action  or
proceeding  by mailing a copy thereof to such party at the address in effect for
notices to it under this Agreement and agrees that such service shall constitute
good and  sufficient  service of process  and  notice  thereof.  Nothing in this
Section  shall  affect or limit any right to serve  process in any other  manner
permitted by law.

except as specifically set forth herein or in the Registration Rights Agreement,
neither the  Company  nor any  Purchaser  makes any  representations,  warranty,

         Section  8.5 WAIVERS.  No waiver by either  party of any  default  with
respect to any provision,  condition or  requirement of this Agreement  shall be
deemed  to be a  continuing  waiver  in the  future  or a  waiver  of any  other

this Agreement are for convenience  only and shall not constitute a part of this
Agreement  for any other  purpose and shall not be deemed to limit or affect any

Agreement to any person (other than to an affiliate of such  Purchaser)  without
the  prior  consent  of the  Company,  which  consent  will not be  unreasonably
withheld.  This Agreement  shall be binding upon and inure to the benefit of the

become effective when  counterparts have been signed by each party and delivered

is required by law,  based upon an opinion of the  Company's  counsel,  that the
Company  must issue a press  release or  otherwise  make a public  statement  or
announcement  with respect to this Agreement  prior to the Closing,  the Company
will  use its best  efforts  to  consult  with  the  Purchasers  on the form and
substance  of such press  release.  After the  Closing,  the Company may issue a
press release or otherwise make a public statement or announcement  with respect

severable  and,  in the event  that any court of  competent  jurisdiction  shall
determine  that  any  one or more of the  provisions  or part of the  provisions
contained  in this  Agreement  shall,  for any  reason,  be held to be  invalid,
illegal  or  unenforceable  in  any  respect,  such  invalidity,  illegality  or
unenforceability  shall not affect any other provision or part of a provision of
this  Agreement,  and this Agreement  shall be reformed and construed as if such
invalid or illegal or unenforceable  provision,  or part of such provision,  had
never been contained herein,  so that such provisions would be valid,  legal and
enforceable to the maximum extent possible.

         Section  8.14  FURTHER  ASSURANCES.  From  and  after  the date of this

carry out and to effectuate fully the intent and purposes of this Agreement, the
Common  Stock,  the Warrants,  the Warrant  Shares and the  Registration  Rights
Agreement.

         2.       SHELF REGISTRATION.

                  On or prior to the Filing Date the Company  shall  prepare and
file  with  the  Commission  a  "shelf"  Registration   Statement  covering  all
Registrable Securities for an offering to be made on a continuous basis pursuant
to Rule 415.  The  Registration  Statement  shall be on Form SB-2 (except if the
Company is not then eligible to register for resale the  Registrable  Securities
on Form SB-2, in which case such  registration  shall be on another  appropriate
form in accordance  herewith).  The Company shall (i) not permit any  securities
other  than  the  Registrable  Securities  to be  included  in the  Registration
Statement and (ii) use its best efforts to cause the  Registration  Statement to
be declared effective under the Securities Act as promptly as possible after the
filing


                                        3

<PAGE>

thereof,  but in any event  prior to the  Effectiveness  Date,  and to keep such
Registration  Statement  continuously  effective  under the Securities Act until
such  date as is the  earlier  of (x) the date when all  Registrable  Securities
covered by such  Registration  Statement have been sold or (y) the date on which
the Registrable  Securities may be sold without any restriction pursuant to Rule
144(k) as determined by the counsel to the Company pursuant to a written opinion
letter,   addressed  to  the  Company's  transfer  agent  to  such  effect  (the
"EFFECTIVENESS  PERIOD"). If the Company is notified orally or in writing by the
Commission that the Commission has no comments with respect to the  Registration
Statement (the "Commission  Notice"),  the Company shall use its best efforts to
cause the Registration Statement to be declared effective no later than five (5)
business  days  after  receipt  of  the  Commission  Notice.  If  an  additional
Registration  Statement  is  required to be filed  because the actual  number of
shares of Common  Stock into which the  Warrants  are  exercisable  exceeds  the
number  of shares  of  Common  Stock  initially  registered  in  respect  of the
Conversion  Shares and the  Warrant  Shares  based upon the  computation  on the
Closing  Date,  the Company  shall have twenty (20)  Business  Days to file such
additional Registration Statement, and the Company shall use its best efforts to
cause such  additional  Registration  Statement to be declared  effective by the
Commission as soon as possible,  but in no event later than forty-five (45) days
after filing.

         3.       REGISTRATION PROCEDURES.

                  In  connection  with the  Company's  registration  obligations
hereunder, the Company shall:

                  (a)  Prepare and file with the  Commission  on or prior to the
Filing  Date,  a  Registration  Statement on Form SB-2 (or if the Company is not
then  eligible to register for resale the  Registrable  Securities  on Form SB-2
such registration shall be on another  appropriate form in accordance  herewith)
in accordance with the method or methods of distribution thereof as specified by
the  Holders  (except  if  otherwise  directed  by the  Holders),  and cause the
Registration  Statement  to become  effective  and remain  effective as provided
herein;  provided,  however,  that not less than five (5) Business Days prior to
the  filing of the  Registration  Statement  or any  related  Prospectus  or any
amendment  or  supplement   thereto   (including  any  document  that  would  be
incorporated therein by reference), the Company shall (i) furnish to the Holders
and any  Special  Counsel,  copies of all such  documents  proposed to be filed,
which documents (other than those  incorporated by reference) will be subject to
the review of such Holders and such Special Counsel,  and (ii) at the request of
any Holder cause its officers and directors,  counsel and independent  certified
public  accountants to respond to such  inquiries as shall be necessary,  in the
reasonable  opinion  of  counsel  to  such  Holders,  to  conduct  a  reasonable
investigation  within the meaning of the  Securities  Act. The Company shall not
file the  Registration  Statement or any such  Prospectus  or any  amendments or
supplements  thereto  to which the  Holders  of a  majority  of the  Registrable
Securities or any Special  Counsel  shall  reasonably  object in writing  within
three (3) Business Days of their receipt thereof.

                  (b) (i) Prepare and file with the Commission such  amendments,
including  post-effective  amendments,  to the Registration  Statement as may be
necessary to keep the Registration


                                        4

<PAGE>


Statement continuously effective as to the applicable Registrable Securities for
the  Effectiveness  Period  and  prepare  and  file  with  the  Commission  such
additional  Registration  Statements  in order to register  for resale under the
Securities  Act  all of the  Registrable  Securities;  (ii)  cause  the  related
Prospectus to be amended or supplemented by any required Prospectus  supplement,
and as so  supplemented  or  amended  to be filed  pursuant  to Rule 424 (or any
similar  provisions then in force)  promulgated  under the Securities Act; (iii)
respond as promptly as possible to any  comments  received  from the  Commission
with  respect to the  Registration  Statement  or any  amendment  thereto and as
promptly  as  possible  provide  the  Holders  true and  complete  copies of all
correspondence   from  and  to  the  Commission  relating  to  the  Registration
Statement;  and (iv) comply in all material  respects with the provisions of the
Securities  Act and the  Exchange  Act with  respect to the  disposition  of all
Registrable   Securities  covered  by  the  Registration  Statement  during  the
applicable  period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

                  (c) Notify the Holders of  Registrable  Securities  to be sold
and any Special  Counsel as promptly  as  possible  (and,  in the case of (i)(A)
below,  not less than  five (5)  Business  Days  prior to such  filing)  and (if
requested by any such  Person)  confirm such notice in writing no later than one
(1) Business Day following  the day (i)(A) when a Prospectus  or any  Prospectus
supplement or post-effective amendment to the Registration Statement is proposed
to be filed; (B) when the Commission  notifies the Company whether there will be
a "review" of such Registration  Statement and whenever the Commission  comments
in  writing  on  such  Registration  Statement  and  (C)  with  respect  to  the
Registration Statement or any post-effective amendment, when the same has become
effective;  (ii) of any request by the  Commission or any other Federal or state
governmental  authority  for  amendments  or  supplements  to  the  Registration
Statement or Prospectus or for additional information;  (iii) of the issuance by
the  Commission  of  any  stop  order   suspending  the   effectiveness  of  the
Registration  Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings  for that purpose;  (iv) if at any time any of the
representations  and  warranties  of the  Company  contained  in  any  agreement
contemplated hereby ceases to be true and correct in all material respects;  (v)
of the receipt by the Company of any notification with respect to the suspension
of the  qualification or exemption from  qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose;  and (vi) of the occurrence of any event that makes
any statement made in the  Registration  Statement or Prospectus or any document
incorporated  or deemed to be  incorporated  therein by reference  untrue in any
material respect or that requires any revisions to the  Registration  Statement,
Prospectus or other documents so that, in the case of the Registration Statement
or the Prospectus,  as the case may be, it will not contain any untrue statement
of a material  fact or omit to state any  material  fact  required  to be stated
therein  or  necessary  to make  the  statements  therein,  in the  light of the
circumstances under which they were made, not misleading.

                       (d) Use its best efforts to avoid the issuance of, or, if
issued,  obtain the withdrawal of, (i) any order suspending the effectiveness of
the Registration Statement or (ii) any suspension


                                        5

<PAGE>


of the qualification (or exemption from qualification) of any of the Registrable
Securities for sale in any jurisdiction, at the earliest practicable moment.

                  (e) If  requested  by the Holders of a majority in interest of
the Registrable Securities,  (i) promptly incorporate in a Prospectus supplement
or  post-effective  amendment to the Registration  Statement such information as
the  Company  reasonably  agrees  should be  included  therein and (ii) make all
required filings of such Prospectus supplement or such post-effective  amendment
as soon as  practicable  after the  Company  has  received  notification  of the
matters to be  incorporated  in such  Prospectus  supplement  or  post-effective
amendment.

                  (f) Furnish to each Holder and any  Special  Counsel,  without
charge,  at least one  conformed  copy of each  Registration  Statement and each
amendment thereto,  including financial statements and schedules,  all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously  furnished or
incorporated by reference)  promptly after the filing of such documents with the
Commission.

                  (g) Promptly  deliver to each Holder and any Special  Counsel,
without charge, as many copies of the Prospectus or Prospectuses (including each
form of prospectus) and each amendment or supplement thereto as such Persons may
reasonably  request;  and  the  Company  hereby  consents  to the  use  of  such
Prospectus  and each  amendment  or  supplement  thereto by each of the  selling
Holders in connection with the offering and sale of the  Registrable  Securities
covered by such Prospectus and any amendment or supplement thereto.

                  (h) Prior to any public  offering of  Registrable  Securities,
use its best  efforts  to  register  or qualify or  cooperate  with the  selling
Holders  and  any  Special  Counsel  in  connection  with  the  registration  or
qualification  (or exemption from such  registration or  qualification)  of such
Registrable  Securities for offer and sale under the securities or Blue Sky laws
of such  jurisdictions  within  the  United  States as any  Holder  requests  in
writing,   to  keep  each  such  registration  or  qualification  (or  exemption
therefrom) effective during the Effectiveness Period and to do any and all other
acts or  things  necessary  or  advisable  to  enable  the  disposition  in such
jurisdictions of the Registrable Securities covered by a Registration Statement;
provided,  however,  that the Company shall not be required to qualify generally
to do business in any jurisdiction  where it is not then so qualified or to take
any  action  that would  subject  it to  general  service of process in any such
jurisdiction  where it is not then so  subject  or  subject  the  Company to any
material tax in any such jurisdiction where it is not then so subject.

                       (i) Cooperate  with the Holders to facilitate  the timely
preparation and delivery of certificates  representing Registrable Securities to
be sold pursuant to a Registration  Statement,  which certificates shall be free
of all restrictive legends,  and to enable such Registrable  Securities to be in
such  denominations  and  registered  in such names as any Holder may request at
least two (2) Business Days prior to any sale of Registrable Securities.


                                        6

<PAGE>


                  (j) Upon the occurrence of any event  contemplated  by Section
3(c)(vi), as promptly as possible, prepare a supplement or amendment,  including
a post-effective amendment, to the Registration Statement or a supplement to the
related  Prospectus or any document  incorporated  or deemed to be  incorporated
therein  by  reference,  and file  any  other  required  document  so  that,  as
thereafter  delivered,  neither the  Registration  Statement nor such Prospectus
will contain an untrue  statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements  therein,
in the light of the circumstances under which they were made, not misleading.

                  (k) Use its best efforts to cause all  Registrable  Securities
relating  to such  Registration  Statement  to be listed on the  American  Stock
Exchange  and  any  other  securities  exchange,  quotation  system,  market  or
over-the-counter  bulletin board, if any, on which similar  securities issued by
the  Company  are then  listed as and when  required  pursuant  to the  Purchase
Agreement.

                  (l) Comply in all material  respects with all applicable rules
and  regulations of the Commission and make generally  available to its security
holders  earning  statements  satisfying  the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than 45 days after the end of any 12-month
period  (or 90 days  after the end of any  12-month  period if such  period is a
fiscal  year)  commencing  on the first day of the first  fiscal  quarter of the
Company after the effective date of the Registration Statement,  which statement
shall conform to the requirements of Rule 158.

                  (m) The Company may require each selling  Holder to furnish to
the  Company  information  regarding  such Holder and the  distribution  of such
Registrable Securities as is required by law to be disclosed in the Registration
Statement,  and the Company may exclude from such  registration  the Registrable
Securities of any such Holder who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

                  If the Registration  Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the  Securities  Act or any similar  federal  statute then in
force)  the  deletion  of the  reference  to such  Holder  in any  amendment  or
supplement to the  Registration  Statement  filed or prepared  subsequent to the
time that such reference ceases to be required.

                  Each Holder covenants and agrees that (i) it will not sell any
Registrable  Securities under the  Registration  Statement until it has received
copies of the  Prospectus as then amended or  supplemented  as  contemplated  in
Section 3(g) and notice from the Company that such  Registration  Statement  and
any  post-effective  amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus


                                        7

<PAGE>

delivery  requirements of the Securities Act as applicable to them in connection
with sales of Registrable Securities pursuant to the Registration Statement.

                  Each  Holder  agrees by its  acquisition  of such  Registrable
Securities  that, upon receipt of a notice from the Company of the occurrence of
any  event of the kind  described  in  Section  3(c)(ii),  3(c)(iii),  3(c)(iv),
3(c)(v) or 3(c)(vi),  such Holder will forthwith discontinue disposition of such
Registrable  Securities  under the  Registration  Statement  until such Holder's
receipt of the copies of the supplemented Prospectus and/or amended Registration
Statement  contemplated  by Section 3(j), or until it is advised in writing (the
"Advice")  by the  Company  that  the use of the  applicable  Prospectus  may be
resumed,  and,  in  either  case,  has  received  copies  of any  additional  or
supplemental  filings  that are  incorporated  or deemed to be  incorporated  by
reference in such Prospectus or Registration Statement.

                  (n) If (i) there is material non-public  information regarding
the Company which the  Company's  Board of Directors  (the  "Board")  reasonably
determines  not to be in the  Company's  best interest to disclose and which the
Company is not  otherwise  required to disclose,  or (ii) there is a significant
business  opportunity  (including,  but  not  limited  to,  the  acquisition  or
disposition  of assets  (other than in the  ordinary  course of business) or any
merger,  consolidation,  tender offer or other similar transaction) available to
the Company  which the Board  reasonably  determines  not to be in the Company's
best  interest to disclose  and which the Company  would be required to disclose
under the  Registration  Statement,  then the  Company  may  postpone or suspend
filing or effectiveness  of a registration  statement for a period not to exceed
20 consecutive  days,  provided that the Company may not postpone or suspend its
obligation under this Section 3(n) for more than 45 days in the aggregate during
any 12 month period (each, a "Blackout Period"); provided, however, that no such
postponement  or suspension  shall be permitted for  consecutive 20 day periods,
arising out of the same set of facts, circumstances or transactions.

         4.       REGISTRATION EXPENSES



                                        8

designate)), (ii) printing expenses (including, without limitation,  expenses of

without  limitation,  all salaries  and  expenses of its officers and  employees
performing  legal or accounting  duties),  the expense of any annual audit,  the
fees and expenses  incurred in  connection  with the listing of the  Registrable
Securities on any securities exchange as required hereunder.

         5.       INDEMNIFICATION

                  (a)  INDEMNIFICATION  BY  THE  COMPANY.   The  Company  shall,
notwithstanding  any termination of this Agreement,  indemnify and hold harmless
each Holder,  the officers,  directors,  agents,  brokers (including brokers who
offer and sell  Registrable  Securities  as principal as a result of a pledge or
any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them,  each Person who controls any such Holder (within
the meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange
Act) and the officers,  directors, agents and employees of each such controlling
Person,  to the fullest extent permitted by applicable law, from and against any
and  all  losses,  claims,  damages,  liabilities,   costs  (including,  without
limitation,   costs  of   preparation   and   attorneys'   fees)  and   expenses
(collectively,  "Losses"), as incurred, arising out of or relating to any untrue
or alleged  untrue  statement of a material fact  contained in the  Registration
Statement, any Prospectus or any form of prospectus or in any amendment or


                                        9

<PAGE>



supplement  thereto  or in any  preliminary  prospectus,  or  arising  out of or
relating to any omission or alleged  omission of a material  fact required to be
stated therein or necessary to make the  statements  therein (in the case of any
Prospectus  or form of prospectus  or  supplement  thereto,  in the light of the
circumstances under which they were made) not misleading,  except to the extent,
but only to the  extent,  that such untrue  statements  or  omissions  are based
solely  upon  information  regarding  such  Holder  furnished  in writing to the
Company  by  such  Holder  expressly  for use  therein,  which  information  was
reasonably  relied on by the  Company for use therein or to the extent that such
information  relates  to  such  Holder  or  such  Holder's  proposed  method  of
distribution of Registrable  Securities and was reviewed and expressly  approved
in writing by such Holder expressly for use in the Registration Statement,  such
Prospectus or such form of Prospectus or in any amendment or supplement thereto.
The Company  shall  notify the Holders  promptly of the  institution,  threat or
assertion of any Proceeding of which the Company is aware in connection with the
transactions contemplated by this Agreement. Such indemnity shall remain in full
force and  effect  regardless  of any  investigation  made by or on behalf of an
Indemnified  Party and shall survive the transfer of the Registrable  Securities
by the Holders.

                  (b) INDEMNIFICATION BY HOLDERS.  Each Holder shall,  severally
and not  jointly,  indemnify  and hold  harmless  the  Company,  the  directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents or employees of such controlling Persons, to
the fullest extent permitted by applicable law, from and against all Losses,  as
incurred,  arising solely out of or based solely upon any untrue  statement of a
material fact contained in the Registration  Statement,  any Prospectus,  or any
form of  prospectus,  or arising solely out of or based solely upon any omission
of a  material  fact  required  to be stated  therein or  necessary  to make the
statements  therein  (in the case of any  Prospectus  or form of  prospectus  or
supplement  thereto,  in the light of the  circumstances  under  which they were
made) not misleading,  to the extent,  but only to the extent,  that such untrue
statement or omission is contained in any information so furnished in writing by
such  Holder to the  Company  specifically  for  inclusion  in the  Registration
Statement or such  Prospectus and that such  information  was reasonably  relied
upon by the Company for use in the  Registration  Statement,  such Prospectus or
such form of prospectus or to the extent that such  information  relates to such
Holder  or  such  Holder's   proposed  method  of  distribution  of  Registrable
Securities  and was  reviewed and  expressly  approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus.  Notwithstanding  anything to the  contrary  contained  herein,  the
Holder  shall be liable under this Section 5(b) for only that amount as does not
exceed the net  proceeds to such  Holder as a result of the sale of  Registrable
Securities pursuant to such Registration Statement.


                  (c) CONDUCT OF INDEMNIFICATION  PROCEEDINGS. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity  hereunder
(an  "Indemnified  Party"),  such  Indemnified  Party  promptly shall notify the
Person from whom indemnity is sought (the "INDEMNIFYING  PARTY) in writing,  and
the Indemnifying Party shall assume the defense thereof,


                                       10

<PAGE>

including the employment of counsel  reasonably  satisfactory to the Indemnified
Party and the  payment of all fees and  expenses  incurred  in  connection  with
defense  thereof;  provided,  that the failure of any Indemnified  Party to give
such notice  shall not  relieve the  Indemnifying  Party of its  obligations  or
liabilities pursuant to this Agreement,  except (and only) to the extent that it
shall  be  finally  determined  by a  court  of  competent  jurisdiction  (which
determination  is not  subject to appeal or further  review)  that such  failure
shall have  proximately  and materially  adversely  prejudiced the  Indemnifying
Party.

                  An Indemnified  Party shall have the right to employ  separate
counsel in any such  Proceeding and to participate in the defense  thereof,  but
the  fees  and  expenses  of  such  counsel  shall  be at the  expense  of  such
Indemnified  Party or Parties unless:  (1) the Indemnifying  Party has agreed in
writing to pay such fees and expenses;  or (2) the Indemnifying Party shall have
failed  promptly to assume the defense of such  Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named  parties to any such  Proceeding  (including  any  impleaded  parties)
include  both  such  Indemnified  Party  and the  Indemnifying  Party,  and such
Indemnified Party shall have been advised by counsel that a conflict of interest
is likely to exist if the same counsel were to represent such Indemnified  Party
and the Indemnifying  Party (in which case, if such  Indemnified  Party notifies
the  Indemnifying  Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense  thereof and such counsel shall be at the expense of
the  Indemnifying  Party).  The  Indemnifying  Party shall not be liable for any
settlement of any such Proceeding  effected without its written  consent,  which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party,  unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

                  All fees and  expenses  of the  Indemnified  Party  (including
reasonable  fees  and  expenses  to  the  extent  incurred  in  connection  with
investigating   or  preparing  to  defend  such   Proceeding  in  a  manner  not
inconsistent  with this  Section)  shall be paid to the  Indemnified  Party,  as
incurred,  within  ten (10)  Business  Days of  written  notice  thereof  to the
Indemnifying  Party  (regardless of whether it is ultimately  determined that an
Indemnified Party is not entitled to indemnification  hereunder;  provided, that
the  Indemnifying  Party may require  such  Indemnified  Party to  undertake  to
reimburse  all such fees and  expenses  to the extent it is  finally  judicially
determined  that  such  Indemnified  Party is not  entitled  to  indemnification
hereunder).

                  (d) CONTRIBUTION. If a claim for indemnification under Section
5(a) or 5(b) is  unavailable  to an  Indemnified  Party  because of a failure or
refusal  of  a  governmental   authority  to  enforce  such  indemnification  in
accordance  with its terms (by reason of public policy or otherwise),  then each
Indemnifying  Party,  in lieu of  indemnifying  such  Indemnified  Party,  shall
contribute to the amount paid or payable by such  Indemnified  Party as a result
of such Losses,  in such  proportion as is  appropriate  to reflect the relative
fault of the Indemnifying Party and Indemnified Party in


                                       11

<PAGE>

connection  with the  actions,  statements  or omissions  that  resulted in such
Losses as well as any other  relevant  equitable  considerations.  The  relative
fault of such  Indemnifying  Party and Indemnified  Party shall be determined by
reference to, among other things, whether any action in question,  including any
untrue or alleged  untrue  statement  of a material  fact or omission or alleged
omission  of a  material  fact,  has  been  taken  or made  by,  or  relates  to
information supplied by, such Indemnifying,  Party or Indemnified Party, and the
parties'  relative intent,  knowledge,  access to information and opportunity to
correct or prevent  such  action,  statement  or  omission.  The amount  paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys' or other
reasonable  fees or  expenses  incurred  by such  party in  connection  with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the  indemnification  provided for in this Section was  available to
such  party  in  accordance  with its  terms.  Notwithstanding  anything  to the
contrary  contained herein, the Holder shall be liable or required to contribute
under this Section 5(c) for only that amount as does not exceed the net proceeds
to such  Holder as a result of the sale of  Registrable  Securities  pursuant to
such Registration Statement.

                  The  parties  hereto  agree  that it  would  not be  just  and
equitable if  contribution  pursuant to this Section 5(d) were determined by pro
rata  allocation  or by any other method of  allocation  that does not take into
account the equitable  considerations  referred to in the immediately  preceding
paragraph. No Person guilty of fraudulent  misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to  contribution  from
any Person who was not guilty of such fraudulent misrepresentation.

                  The indemnity and  contribution  agreements  contained in this
Section are in addition to any liability that the Indemnifying  Parties may have
to the Indemnified Parties

         6. RULE 144.

                  As long as any Holder owns Common  Stock,  Warrants or Warrant
Shares,  the Company  covenants to timely file (or obtain  extensions in respect
thereof and file within the applicable  grace period) all reports required to be
filed by the Company after the date hereof pursuant to Section 13(a) or 15(d) of
the  Exchange  Act and to promptly  furnish the Holders  with true and  complete
copies of all such filings. As long as any Holder owns Common Stock, Warrants or
Warrant  Shares,  if the  Company is not  required to file  reports  pursuant to
Section  13(a) or 15(d) of the Exchange  Act, it will prepare and furnish to the
Holders and make publicly  available in accordance with Rule 144(c)  promulgated
under the Securities  Act annual and quarterly  financial  statements,  together
with a  discussion  and  analysis  of such  financial  statements  in  form  and
substance  substantially similar to those that would otherwise be required to be
included in reports  required by Section  13(a) or 15(d) of the Exchange Act, as
well as any other  information  required  thereby,  in the time period that such
filings  would have been  required to have been made under the Exchange Act. The
Company  further  covenants  that it will take such further action as any Holder
may reasonably  request,  all to the extent required from time to time to enable
such Person to sell


                                       12

<PAGE>

Common Stock and Warrant  Shares without  registration  under the Securities Act
within the limitation of the exemptions  provided by Rule 144 promulgated  under
the Securities Act,  including  providing any legal opinions  referred to in the
Purchase Agreement. Upon the request of any Holder, the Company shall deliver to
such Holder a written  certification of a duly authorized  officer as to whether
it has complied with such requirements.

         7.       MISCELLANEOUS.

                  (a) REMEDIES.  In the event of a breach by the Company or by a
Holder,  of any of their  obligations  under this Agreement,  each Holder or the
Company,  as the case may be, in  addition to being  entitled  to  exercise  all
rights granted by law and under this Agreement,  including  recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary  damages would not provide  adequate
compensation  for any losses  incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific  performance  in respect of such breach,  it shall waive the
defense that a remedy at law would be adequate.

                  (b) No INCONSISTENT AGREEMENTS. Neither the Company nor any of
its  subsidiaries  has,  as of the date hereof  entered  into and  currently  in
effect,  nor shall the Company or any of its subsidiaries,  on or after the date
of this Agreement,  enter into any agreement with respect to its securities that
is  inconsistent  with the rights  granted to the Holders in this  Agreement  or
otherwise conflicts with the provisions hereof.  Without limiting the generality
of the  foregoing,  without the written  consent of the Holders of a majority of
the then outstanding Registrable Securities,  the Company shall not grant to any
Person the right to  request  the  Company to  register  any  securities  of the
Company under the Securities Act unless the rights so granted are subject in all
respects to the prior  rights in full of the Holders set forth  herein,  and are
not  otherwise  in  conflict  with  the  provisions  of this  Agreement,  or the
Registration Rights Agreement has been declared effective by the SEC.

                  (c) NO PIGGYBACK ON REGISTRATIONS. Neither the Company nor any
of its security holders (other than the Holders in such capacity pursuant hereto
and the Persons  listed on Schedule  7(c) hereto) may include  securities of the
Company in the Registration Statement,  and the Company shall not after the date
hereof  enter into any  agreement  providing  such right to any of its  security
holders,  unless the right so granted  is subject in all  respects  to the prior
rights in full of the Holders set forth herein, and is not otherwise in conflict
with the provisions of this Agreement.

                  (d) PIGGY-BACK REGISTRATIONS. If at any time when there is not
an effective  Registration  Statement covering (i) the Shares of Common Stock or
(ii) the Warrant  Shares,  the Company shall  determine to prepare and file with
the  Commission  a  registration  statement  relating to an offering for its own
account or the account of others under the  Securities  Act of any of its equity
securities,  other than on Form S-4 or Form S-8 (each as  promulgated  under the
Securities  Act) or its then  equivalents  relating to equity  securities  to be
issued solely in connection with any


                                       13

<PAGE>



acquisition  of  any  entity  or  business  or  equity  securities  issuable  in
connection with stock option or other employee  benefit plans, the Company shall
send  to  each  holder  of  Registrable   Securities   written  notice  of  such
determination  and, if within thirty (30) days after receipt of such notice, any
such  holder  shall so request in  writing  (which  request  shall  specify  the
Registrable  Securities  intended  to be  disposed  of by the  Purchasers),  the
Company will cause the registration  under the Securities Act of all Registrable
Securities which the Company has been so requested to register by the holder, to
the extent requisite to permit the disposition of the Registrable  Securities so
to be  registered,  provided that if at any time after giving  written notice of
its intention to register any  securities and prior to the effective date of the
registration  statement filed in connection with such registration,  the Company
shall determine for any reason not to register or to delay  registration of such
securities,  the  Company  may, at its  election,  give  written  notice of such
determination to such holder and, thereupon,  (i) in the case of a determination
not to register, shall be relieved of its obligation to register any Registrable
Securities in connection with such  registration (but not from its obligation to
pay expenses in  accordance  with  Section 4 hereof),  and (ii) in the case of a
determination to delay registering,  shall be permitted to delay registering any
Registrable  Securities being  registered  pursuant to this Section 7(d) for the
same period as the delay in registering such other securities. The Company shall
include  in such  registration  statement  all or any  part of such  Registrable
Securities such holder requests to be registered;  provided,  however,  that the
Company shall not be required to register any Registrable Securities pursuant to
this  Section  7(d) that are  eligible  for sale  pursuant to Rule 144(k) of the
Securities Act. In the case of an underwritten public offering,  if the managing
underwriter(s)  or  underwriter(s)  should reasonably object to the inclusion of
the Registrable Securities in such registration  statement,  then if the Company
after  consultation with the managing  underwriter  should reasonably  determine
that the inclusion of such Registrable  Securities,  would materially  adversely
affect the offering  contemplated in such registration  statement,  and based on
such determination  recommends inclusion in such registration statement of fewer
or none of the  Registrable  Securities  of the Holders,  then (x) the number of
Registrable  Securities of the Holders included in such  registration  statement
shall  be  reduced  pro-rata  among  such  Holders  (based  upon the  number  of
Registrable  Securities  requested to be included in the  registration),  if the
Company after consultation with the  underwriter(s)  recommends the inclusion of
fewer Registrable  Securities,  or (y) none of the Registrable Securities of the
Holders shall be included in such registration  statement,  if the Company after
consultation  with the  underwriter(s)  recommends the inclusion of none of such
Registrable Securities;  provided, however, that if securities are being offered
for the  account  of other  persons or  entities  as well as the  Company,  such
reduction  shall not represent a greater  fraction of the number of  Registrable
Securities  intended to be offered by the Holders  than the  fraction of similar
reductions imposed on such other persons or entities (other than the Company).

                  (e) FAILURE TO FILE  REGISTRATION  STATEMENT AND OTHER EVENTS.
The Company and the Purchasers agree that the Holders will suffer damages if the
Registration  Statement  is not  filed on or prior  to the  Filing  Date and not
declared  effective by the Commission on or prior to the Effectiveness  Date and
maintained in the manner contemplated herein during the Effectiveness Time or if
certain  other events occur.  The Company and the Holders  further agree that it
would not be


                                       14

<PAGE>



feasible to ascertain the extent of such damages with precision. Accordingly, if
(i) the  Registration  Statement is not filed on or prior to the Filing Date, or
is not declared  effective by the  Commission  on or prior to the  Effectiveness
Date (or in the event an additional  Registration Statement is filed because the
actual number of shares of Common Stock into which the Warrants are  exercisable
exceeds the number of shares of Common Stock  initially  registered is not filed
and declared  effective  within the time periods set forth in Section 2(a)),  or
(ii) the Company fails to file with the Commission a request for acceleration in
accordance with Rule 12dl-2  promulgated  under the Exchange Act within five (5)
Business  Days of the date that the Company is  notified  (orally or in writing,
whichever is earlier) by the Commission  that a Registration  Statement will not
be  "reviewed,"  or not  subject to further  review,  or (iii) the  Registration
Statement is filed with and declared  effective by the Commission but thereafter
ceases to be effective as to all Registrable Securities at any time prior to the
expiration of the Effectiveness Period, without being succeeded immediately by a
subsequent  Registration  Statement  filed with and  declared  effective  by the
Commission,  and such  cessation  continues  for a period of thirty  days  after
written notice thereof to the Company, or (iv) trading in the Common Stock shall
be suspended or if the Common Stock is delisted from the American Stock Exchange
for any reason  for more than three  Business  Days in the  aggregate,  and such
suspension  or delisting  continues  for a period of fourteen days after written
notice thereof to the Company, or (v) the Company breaches in a material respect
any covenant or other  material  term or condition to this  Agreement,  Purchase
Agreement (other than a  representation  or warranty  contained  therein) or any
other  agreement,   document,  certificate  or  other  instrument  delivered  in
connection  with the  transactions  contemplated  hereby and  thereby,  and such
breach continues for a period of thirty days after written notice thereof to the
Company,  or (vii) the Company has breached  Section 3(n) of this Agreement (any
such failure or breach being  referred to as an "Event"),  the Company shall pay
in cash as  liquidated  damages  for such  failure  and not as a penalty to each
Holder an amount  equal to 2% of such  Holder's  pro rata share of the  purchase
price paid by all  Holders  for all shares of Common  Stock  purchased  and then
outstanding  pursuant to the Purchase  Agreement for each thirty (30) day period
until the  applicable  Event has been  cured,  which shall be pro rated for such
periods less than thirty (30) days (the "Periodic Amount").  Payments to be made
pursuant to this Section 7(e) shall be due and payable in cash  immediately upon
demand.  The parties  agree that the  Periodic  Amount  represents  a reasonable
estimate on the part of the parties,  as of the date of this  Agreement,  of the
amount of  damages  that may be  incurred  by the  Holders  if the  Registration
Statement  is not filed on or prior to the Filing Date or has not been  declared
effective by the Commission on or prior to the Effectiveness Date and maintained
in the manner  contemplated herein during the Effectiveness Time or if any other
Event as described herein has occurred.

                  (f)      SPECIFIC ENFORCEMENT, CONSENT TO JURISDICTION.

                       (i) The Company and the Purchasers  acknowledge and agree
that  irreparable  damage would occur in the event that any of the provisions of
this Registration  Rights Agreement or the Purchase Agreement were not performed
in  accordance  with their  specific  terms or were  otherwise  breached.  It is
accordingly agreed that the parties shall be entitled to an injunction


                                       15

<PAGE>


or   injunctions  to  prevent  or  cure  breaches  of  the  provisions  of  this
Registration   Rights  Agreement  or  the  Purchase  Agreement  and  to  enforce
specifically the terms and provisions hereof or thereof,  this being in addition
to any other remedy to which any of them may be entitled by law or equity.

                       (ii) Each of the  Company and the  Purchasers  (i) hereby
irrevocably  submits to the  jurisdiction  of the United States  District  Court
sitting  in the  Southern  District  of New York for the  purposes  of any suit,
action  or  proceeding  arising  out of or  relating  to this  Agreement  or the
Purchase  Agreement and (ii) hereby waives, and agrees not to assert in any such
suit, action or proceeding,  any claim that it is not personally  subject to the
jurisdiction of such court, that the suit, action or proceeding is brought in an
inconvenient  forum or that the  venue of the  suit,  action  or  proceeding  is
improper.  Each of the Company  and the  Purchasers  consents  to process  being
served in any such suit,  action or proceeding by mailing a copy thereof to such
party at the address in effect for notices to it under this Agreement and agrees
that such service shall  constitute  good and sufficient  service of process and
notice thereof.  Nothing in this Section 7(f) shall affect or limit any right to
serve process in any other manner permitted by law.

                  (g) AMENDMENTS AND WAIVERS.  The provisions of this Agreement,
including  the  provisions  of this  sentence,  may not be amended,  modified or
supplemented,  and waivers or consents to departures from the provisions  hereof
may not be given,  unless the same shall be in writing and signed by the Company
and each of the Holders.  Notwithstanding the foregoing,  a waiver or consent to
depart  from  the  provisions  hereof  with  respect  to a matter  that  relates
exclusively  to the rights of Holders and that does not  directly or  indirectly
affect  the  rights  of other  Holders  may be given  by  Holders  of at least a
majority of the Registrable  Securities to which such waiver or consent relates;
provided,  however,  that the  provisions  of this  sentence may not be amended,
modified,  or  supplemented  except in  accordance  with the  provisions  of the
immediately preceding sentence.

                  (h) NOTICES.  Any and all notices or other  communications  or
deliveries  required or permitted to be provided  hereunder  shall be in writing
and  shall be deemed  given  and  effective  on the  earlier  of (i) the date of

facsimile  telephone  number  specified  for notice prior to 5:00 p.m.,  eastern
standard  time,  on a  Business  Day,  (ii) the  Business  Day after the date of
transmission,  if such notice or communication is delivered via facsimile at the
facsimile  telephone number  specified for notice later than 5:00 p.m.,  eastern
standard time, on any date and earlier than 11:59 p.m.,  eastern  standard time,
on such date,  (iii) the Business Day following the date of mailing,  if sent by
nationally  recognized  overnight  courier service or (iv) actual receipt by the
party to whom  such  notice is  required  to be given.  The  addresses  for such
communications  shall be with  respect to each  Holder at its  address set forth
under its name on Schedule A attached  hereto,  or with  respect to the Company,
addressed to:

                  Datametrics Corporation

or to such other address or addresses or facsimile number or numbers as any such
party may most recently have  designated in writing to the other parties  hereto
by such notice.  Copies of notices to the Company shall be sent to Lane Altman &

Mazzella,  Esq., Facsimile No.: (617) 345-0400.  Copies of notices to any Holder

Facsimile No.:

                  (i)  SUCCESSORS AND ASSIGNS.  This Agreement  shall be binding
upon and inure to the benefit of the parties and their  successors and permitted
assigns and shall inure to the  benefit of each  Holder and its  successors  and
assigns.  The  Company  may not assign  this  Agreement  or any of its rights or
obligations  hereunder  without the prior written  consent of each Holder.  Each
Purchaser  may assign its rights  hereunder  in the manner and to the Persons as
permitted under the Purchase Agreement.

                  (j)  ASSIGNMENT  OF  REGISTRATION  RIGHTS.  The rights of each
Holder  hereunder,  including the right to have the Company  register for resale
Registrable Securities in accordance with the terms of this Agreement,  shall be
automatically  assignable by each Holder to any transferee of such Holder of all
or a portion of the shares of Common Stock or the Registrable Securities if: (i)
the Holder  agrees in writing  with the  transferee  or  assignee to assign such
rights,  and a copy of such  agreement  is  furnished  to the  Company  within a
reasonable time after such assignment,  (ii) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (a) the
name and address of such  transferee or assignee,  and (b) the  securities  with
respect to which such  registration  rights are being  transferred  or assigned,
(iii)  following  such transfer or assignment  the further  disposition  of such
securities by the transferee or assignees is restricted under the Securities Act
and applicable  state  securities  laws,  (iv) at or before the time the Company
receives the written  notice  contemplated  by clause (ii) of this Section,  the
transferee or assignee  agrees in writing with the Company to be bound by all of
the provisions of this Agreement,  and (v) such transfer shall have been made in
accordance  with the  applicable  requirements  of the  Purchase  Agreement.  In
addition, each Holder shall have the right to assign its rights hereunder to any
other Person with the prior written consent of the Company,  which consent shall
not be  unreasonably  withheld.  The  rights to  assignment  shall  apply to the
Holders (and to subsequent) successors and assigns.

                  (k) COUNTERPARTS. This Agreement may be executed in any number
of  counterparts,  each of  which  when so  executed  shall be  deemed  to be an
original  and, all of which taken  together  shall  constitute  one and the same
Agreement.   In  the  event  that  any   signature  is  delivered  by  facsimile
transmission, such signature shall create a valid binding obligation of the


                                       17

<PAGE>


party  executing  (or on whose behalf such  signature is executed) the same with
the same  force and  effect as if such  facsimile  signature  were the  original
thereof.

                  (l)  GOVERNING  LAW. This  Agreement  shall be governed by and
construed in accordance  with the laws of the State of New York,  without regard
to principles of conflicts of law thereof.

                  (m)  CUMULATIVE  REMEDIES.  The remedies  provided  herein are
cumulative and not exclusive of any remedies provided by law.

                  (n)  SEVERABILITY.   If  any  term,  provision,   covenant  or
restriction  of  this  Agreement  is  held  to  be  invalid,  illegal,  void  or
unenforceable in any respect, the remainder of the terms, provisions,  covenants
and  restrictions  set forth  herein  shall  remain in full force and effect and
shall in no way be affected,  impaired or  invalidated,  and the parties  hereto
shall use their  reasonable  efforts to find and employ an alternative  means to
achieve the same or substantially  the same result as that  contemplated by such
term, provision,  covenant or restriction.  It is hereby stipulated and declared
to be the  intention of the parties that they would have  executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

                  (o) HEADINGS. The headings herein are for convenience only, do
not  constitute  a part of this  Agreement  and  shall not be deemed to limit or
affect any of the provisions hereof.

                  (p) SHARES HELD BY THE COMPANY  AND ITS  AFFILIATES.  Whenever
the  consent or approval of Holders of a  specified  percentage  of  Registrable
Securities is required hereunder,  Registrable Securities held by the Company or
its  Affiliates  (other than any Holder or  transferees or successors or assigns
thereof  if such  Holder is deemed  to be an  Affiliate  solely by reason of its
holdings of such  Registrable  Securities)  shall not be counted in  determining
whether  such  consent or  approval  was given by the  Holders of such  required
percentage.

                  (q)  Within  two (2)  business  days  after  the  Registration
Statement which includes the Registrable  Securities is ordered effective by the
Commission,  the Company  shall  deliver,  and shall cause legal counsel for the
Company to deliver, to the transfer agent for such Registrable  Securities (with
copies  to the  Holders  whose  Registrable  Securities  are  included  in  such
Registration  Statement)  confirmation that the Registration  Statement has been
declared effective by the Commission in the form attached hereto as Exhibit A.

[TRANSFER AGENT]
Attn:_________________

                  Re:      DATAMETRICS CORPORATION

Ladies and Gentlemen:

         We are counsel to Datametrics Corporation,  a Delaware corporation (the
"COMPANY"),  and have  represented  the Company in connection  with that certain
Common Stock Purchase Agreement (the "PURCHASE  AGREEMENT")  entered into by and
among the Company and the entities a party thereto (the  "HOLDERS")  pursuant to
which the Company  issued to the Holders  shares of its common stock,  par value
$.01 per share (the  "COMMON  STOCK"),  and  warrants to purchase  shares of the
Common Stock (the "WARRANTS").  Pursuant to the Purchase Agreement,  the Company
also has  entered  into a  Registration  Rights  Agreement  with the Holder (the
"REGISTRATION  RIGHTS  AGREEMENT")  pursuant to which the Company agreed,  among
other  things,  to  register  the  Registrable  Securities  (as  defined  in the
Registration  Rights  Agreement),  including the shares of Common Stock issuable
upon exercise of the Warrants, under the Securities Act of 1933, as amended (the
"1933 ACT"). In connection with the Company's obligations under the Registration
Rights  Agreement,  on ____________  ___, 1999, the Company filed a Registration
Statement  on  Form  SB-2  (File  No.   333-_____________)   (the  "REGISTRATION
STATEMENT") with the Securities and Exchange  Commission (the "SEC") relating to
the  Registrable  Securities  which  names  each  of the  Holders  as a  selling
stockholder thereunder.

         In connection  with the  foregoing,  we advise you that a member of the
SEC's  staff has  advised  us by  telephone  that the SEC has  entered  an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF  EFFECTIVENESS]  on [ENTER DATE OF  EFFECTIVENESS]  and we have no knowledge,
after  telephonic  inquiry of a member of the SEC's  staff,  that any stop order
suspending its  effectiveness  has been issued or that any  proceedings for that
purpose  are  pending  before,  or  threatened  by, the SEC and the  Registrable
Securities  are  available  for  resale  under  the  1933  Act  pursuant  to the
Registration Statement.

                                                     Very truly yours,

                                                     [COMPANY'S COUNSEL]

                                                     By:________________________

                                 FORM OF WARRANT


THIS WARRANT AND THE SHARES OF COMMON STOCK  ISSUABLE UPON EXERCISE  HEREOF HAVE
NOT  BEEN  REGISTERED  UNDER  THE  SECURITIES  ACT  OF  1933,  AS  AMENDED  (THE
"SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED
OR OTHERWISE  DISPOSED OF UNLESS  REGISTERED  UNDER THE SECURITIES ACT AND UNDER
APPLICABLE STATE SECURITIES LAWS OR DATAMETRICS  CORPORATION SHALL HAVE RECEIVED
AN  OPINION  OF ITS  COUNSEL  THAT  REGISTRATION  OF SUCH  SECURITIES  UNDER THE
SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE  STATE  SECURITIES LAWS IS
NOT REQUIRED.


                               WARRANT TO PURCHASE

                             SHARES OF COMMON STOCK

                                       OF

                             DATAMETRICS CORPORATION

                               Expires May 7, 2004

No.: W-__                                           Number of Shares: __________
Date of Issuance: May 7, 1999


         FOR VALUE  RECEIVED,  subject to the provisions  hereinafter set forth,
the undersigned,  Datametrics Corporation, a Delaware corporation (together with
its   successors   and   assigns,   the   "Issuer"),   hereby   certifies   that
___________________  or its registered  assigns is entitled to subscribe for and
purchase,  during the period specified in this Warrant, up to ___________ shares
(subject to adjustment as hereinafter provided) of the duly authorized,  validly
issued, fully paid and non-assessable Common Stock of the Issuer, at an exercise
price per share equal to the Warrant Price then in effect, subject,  however, to
the  provisions  and  upon the  terms  and  conditions  hereinafter  set  forth.
Capitalized  terms used in this Warrant and not otherwise  defined  herein shall
have the respective meanings specified in Section 7 hereof.

         1. TERM.  The right to  subscribe  for and  purchase  shares of Warrant
Stock represented  hereby shall commence on the date of issuance of this Warrant
and shall expire at




                                        1

<PAGE>



5:00 p.m.,  eastern time, on the fifth  anniversary of the Closing Date (as such
term is defined in the Purchase Agreement) (such period being the "Term").

         2. METHOD OF EXERCISE  PAYMENT:  ISSUANCE OF NEW WARRANT:  TRANSFER AND
EXCHANGE.

         (a) TIME OF EXERCISE.  The purchase rights  represented by this Warrant
may be  exercised  in whole or in part at any time and from time to time  during
the Term.

         (b) METHOD OF EXERCISE. The Holder hereof may exercise this Warrant, in
whole or in part,  by the  surrender  of this Warrant  (with the  exercise  form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment  to the  Issuer  of an  amount of  consideration  therefor  equal to the
Warrant Price in effect on the date of such exercise multiplied by the number of
shares of  Warrant  Stock  with  respect  to which  this  Warrant  is then being
exercised,  payable at such Holder's  election (i) by certified or official bank
check or (ii) by surrender to the Issuer for  cancellation  of a portion of this
Warrant  representing  that number of unissued  shares of Warrant Stock which is
equal  to the  quotient  obtained  by  dividing  (A)  the  product  obtained  by
multiplying  the  Warrant  Price by the number of shares of Warrant  Stock being
purchased upon such exercise by (B) the difference  obtained by subtracting  the
Warrant  Price from the Per Share Market Value as of the date of such  exercise,
or (iii) by a combination  of the foregoing  methods of payment  selected by the
Holder of this Warrant.  In any case where the  consideration  payable upon such
exercise is being paid in whole or in part pursuant to the  provisions of clause
(ii) of this  subsection  (b), such  exercise  shall be  accompanied  by written
notice from the Holder of this Warrant  specifying the manner of payment thereof
and containing a calculation  showing the number of shares of Warrant Stock with
respect to which rights are being  surrendered  thereunder and the net number of
shares to be issued after giving effect to such surrender.

         (c) ISSUANCE OF STOCK CERTIFICATES. In the event of any exercise of the
rights  represented by this Warrant in accordance  with and subject to the terms
and  conditions  hereof,  (i)  certificates  for the shares of Warrant  Stock so
purchased  shall be dated the date of such  exercise and delivered to the Holder
hereof within a reasonable  time,  not  exceeding  three Trading Days after such
exercise,  and the  Holder  hereof  shall be deemed for all  purposes  to be the
Holder  of the  shares  of  Warrant  Stock so  purchased  as of the date of such
exercise,  and (ii) unless this Warrant has expired, a new Warrant  representing
the  number of shares of  Warrant  Stock,  if any,  with  respect  to which this
Warrant shall not then have been exercised  (less any amount thereof which shall
have been  canceled  in  payment  or partial  payment  of the  Warrant  Price as
hereinabove  provided) shall also be issued to the Holder hereof at the Issuer's
expense within such time.

         (d)  TRANSFERABILITY OF WARRANT.  Subject to Section 2(e), this Warrant
may be  transferred  by a  Purchaser  without  the  consent of the  Company.  If
transferred  pursuant  to  this  paragraph  and  subject  to the  provisions  of
subsection  (e) of this Section 2, this Warrant may be  transferred on the books
of the Issuer by the Holder hereof in person or by duly authorized


                                        2

<PAGE>


attorney,  upon surrender of this Warrant at the principal office of the Issuer,
properly  endorsed (by the Holder  executing an  assignment in the form attached
hereto) and upon payment of any  necessary  transfer  tax or other  governmental
charge imposed upon such transfer. This Warrant is exchangeable at the principal
office of the Issuer for Warrants for the purchase of the same aggregate  number
of shares of Warrant Stock,  each new Warrant to represent the right to purchase
such number of shares of Warrant Stock as the Holder  hereof shall  designate at
the time of such exchange.  All Warrants  issued on transfers or exchanges shall
be dated the Original Issue Date and shall be identical with this Warrant except
as to the number of shares of Warrant Stock issuable pursuant hereto.

         (e)      COMPLIANCE WITH SECURITIES LAWS.

                  (i)  The  Holder  of  this  Warrant,   by  acceptance  hereof,
         acknowledges  that this  Warrant or the  shares of Warrant  Stock to be
         issued upon exercise  hereof are being acquired solely for the Holder's
         own  account  and  not as a  nominee  for  any  other  party,  and  for
         investment,  and that the  Holder  will not  offer,  sell or  otherwise
         dispose of this  Warrant  or any  shares of Warrant  Stock to be issued
         upon  exercise  hereof  except  pursuant to an  effective  registration
         statement, or an exemption from registration,  under the Securities Act
         and any applicable state securities laws.

                  (ii) Except as provided in paragraph (iii) below, this Warrant
         and all certificates  representing  shares of Warrant Stock issued upon
         exercise  hereof  shall  be  stamped  or  imprinted  with a  legend  in
         substantially the following form:

                           THIS WARRANT AND THE SHARES OF COMMON STOCK  ISSUABLE
                  UPON  EXERCISE  HEREOF  HAVE NOT  BEEN  REGISTERED  UNDER  THE
                  SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES  ACT"), OR
                  ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD,  TRANSFERRED OR
                  OTHERWISE  DISPOSED OF UNLESS  REGISTERED UNDER THE SECURITIES
                  ACT AND UNDER  APPLICABLE STATE SECURITIES LAWS OR DATAMETRICS
                  CORPORATION SHALL HAVE RECEIVED AN OPINION OF ITS COUNSEL THAT
                  REGISTRATION OF SUCH  SECURITIES  UNDER THE SECURITIES ACT AND
                  UNDER THE PROVISIONS OF APPLICABLE  STATE  SECURITIES  LAWS IS
                  NOT REQUIRED.

                  (iii) The restrictions imposed by this subsection (e) upon the
         transfer  of this  Warrant  and  the  shares  of  Warrant  Stock  to be
         purchased upon exercise hereof shall terminate (A) when such securities
         shall have been  effectively  registered  under the Securities Act, (B)
         upon  the  Issuer's  receipt  of an  opinion  of  counsel,  in form and
         substance  reasonably  satisfactory  to the  Issuer,  addressed  to the
         Issuer to the effect that


                                        3

<PAGE>


         such  restrictions are no longer required to ensure compliance with the
         Securities  Act and  state  securities  laws or (C) upon  the  Issuer's
         receipt of other evidence  reasonably  satisfactory  to the Issuer that
         such registration and qualification  under state securities laws is not
         required.  Whenever such  restrictions  shall cease and terminate as to
         any such  securities,  the Holder  thereof shall be entitled to receive
         from the Issuer (or its transfer agent and registrar),  without expense
         (other than  applicable  transfer  taxes, if any), new Warrants (or, in
         the case of shares of Warrant Stock,  new stock  certificates)  of like
         tenor not bearing the  applicable  legend  required by  paragraph  (ii)
         above relating to the Securities Act and state securities laws.

         (f) CONTINUING RIGHTS OF HOLDER.  The Issuer will, at the time of or at
any time after each  exercise  of this  Warrant,  upon the request of the Holder
hereof,  acknowledge in writing the extent, if any, of its continuing obligation
to afford to such  Holder all rights to which such Holder  shall  continue to be
entitled  after such  exercise  in  accordance  with the terms of this  Warrant,
provided  that if any such  Holder  shall  fail to make any  such  request,  the
failure shall not affect the continuing  obligation of the Issuer to afford such
rights to such Holder.

         3.      STOCK FULLY PAID: RESERVATION AND LISTING OF SHARES: COVENANTS.

         (a) STOCK FULLY PAID. The Issuer  represents,  warrants,  covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise  hereunder  will, upon issuance,  be duly  authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges  created by or through Issuer.  The Issuer further  covenants and agrees
that during the period  within which this Warrant may be  exercised,  the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise  of this  Warrant a  sufficient  number  of  shares of Common  Stock to
provide for the exercise of this Warrant.

         (b) RESERVATION.  If any shares of Common Stock required to be reserved
for issuance  upon exercise of this Warrant or as otherwise  provided  hereunder
require registration or qualification with any governmental  authority under any
federal or state law before  such  shares may be so issued,  the Issuer  will in
good faith use its best efforts as  expeditiously  as possible at its expense to
cause such shares to be duly  registered or qualified.  If the Issuer shall list
any shares of Common Stock on any securities  exchange or market it will, at its
expense,  list thereon,  maintain and increase when necessary such listing,  of,
all  shares of Warrant  Stock from time to time  issued  upon  exercise  of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable  securities  exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder,  so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities  exchange or
market, and will maintain such listing of, any other securities which the Holder
of this  Warrant  shall be entitled to receive upon the exercise of this Warrant
if at the time  any  securities  of the  same  class  shall  be  listed  on such
securities exchange or market by the Issuer.



                                        4

<PAGE>


         (c) COVENANTS.  The Issuer shall not by any action  including,  without
limitation,  amending the  Certificate  of  Incorporation  or the by-laws of the
Issuer,  or through  any  reorganization,  transfer  of  assets,  consolidation,
merger,  dissolution,  issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such  actions as may be  necessary  or  appropriate  to
protect  the  rights  of the  Holder  hereof  against  dilution  (to the  extent
specifically provided herein) or impairment.  Without limiting the generality of
the  foregoing,  the Issuer  will (i) not permit the par value,  if any,  of its
Common  Stock to exceed  the then  effective  Warrant  Price,  (ii) not amend or
modify any  provision  of the  Certificate  of  Incorporation  or by-laws of the
Issuer  in any  manner  that  would  adversely  affect  in any way  the  powers,
preferences or relative  participating,  optional or other special rights of the
Common  Stock or which would  adversely  affect the rights of the Holders of the
Warrants,  (iii) take all such action as may be  reasonably  necessary  in order
that the Issuer may  validly  and  legally  issue  fully paid and  nonassessable
shares of Common Stock,  free and clear of any liens,  claims,  encumbrances and
restrictions  (other than as provided herein) upon the exercise of this Warrant,
and (iv) use its best efforts to obtain all such  authorizations,  exemptions or
consents from any public regulatory body having  jurisdiction  thereof as may be
reasonably  necessary to enable the Issuer to perform its obligations under this
Warrant.

         (d) LOSS,  THEFT,  DESTRUCTION  OF  WARRANTS.  Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft,  destruction
or  mutilation  of any  Warrant  and,  in the  case of any such  loss,  theft or
destruction,  upon receipt of indemnity or security  satisfactory  to the Issuer
or, in the case of any such mutilation,  upon surrender and cancellation of such
Warrant,  the  Issuer  will  make and  deliver,  in lieu of such  lost,  stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

         (e) RIGHTS AND OBLIGATIONS UNDER THE REGISTRATION RIGHTS AGREEMENT. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the  Registration  Rights  Agreement dated as of even date herewith  between the
Issuer and the Holders  listed on the  signature  pages thereof (as amended from
time to time, the  "Registration  Rights  Agreement").  The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

         4. ADJUSTMENT OF WARRANT PRICE AND WARRANT SHARE NUMBER. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to  adjustment  from time to time upon the  happening  of
certain events as follows:

         (a) RECAPITALIZATION,  REORGANIZATION, RECLASSIFICATION, CONSOLIDATION,
MERGER OR SALE.  (i) In case the Issuer after the  Original  Issue Date shall do
any of the following (each, a "Triggering Event"): (a) consolidate with or merge
into any other  Person and the Issuer shall not be the  continuing  or surviving
corporation of such consolidation or merger, or (b) permit any


                                        5

<PAGE>


other Person to  consolidate  with or merge into the Issuer and the Issuer shall
be the continuing or surviving Person but, in connection with such consolidation
or merger,  any Capital  Stock of the Issuer  shall be changed into or exchanged
for  Securities  of any  other  Person  or cash or any  other  property,  or (c)
transfer  all or  substantially  all of its  properties  or  assets to any other
Person,  or (d)  effect a  capital  reorganization  or  reclassification  of its
Capital  Stock,  then,  and in the case of each such  Triggering  Event,  proper
provision  shall be made so that, upon the basis and the terms and in the manner
provided in this Warrant,  the Holder of this Warrant shall be entitled (x) upon
the exercise hereof at any time after the consummation of such Triggering Event,
to the extent this Warrant is not exercised prior to such  Triggering  Event, or
is redeemed in connection with such Triggering  Event, to receive at the Warrant
Price in  effect  at the time  immediately  prior  to the  consummation  of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering  Event,  the  Securities,  cash and property to
which  such  Holder  would  have been  entitled  upon the  consummation  of such
Triggering  Event if such Holder had  exercised the rights  represented  by this
Warrant  immediately  prior  thereto,   subject  to  adjustments  and  increases
(subsequent  to such corporate  action) as nearly  equivalent as possible to the
adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person  continuing  after or surviving such  Triggering  Event, or to the
Issuer (if Issuer is the continuing or surviving  Person) at a sales price equal
to the  amount  of cash,  property  and/or  Securities  to which a holder of the
number of shares of Common Stock which would  otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date or
closing of any such  Triggering  Event  (the  "Event  Consideration"),  less the
amount or portion of such Event  Consideration  having a fair value equal to the
aggregate  Warrant  Price  applicable  to this Warrant or the portion  hereof so
sold.

         (ii)  Notwithstanding   anything  contained  in  this  Warrant  to  the
contrary,  the Issuer will not effect any Triggering Event unless,  prior to the
consummation  thereof, each Person (other than the Issuer) which may be required
to deliver any Securities, cash or property upon the exercise of this Warrant as
provided herein shall assume, by written instrument delivered to, and reasonably
satisfactory  to, the Holder of this Warrant,  (A) the obligations of the Issuer
under this  Warrant (and if the Issuer shall  survive the  consummation  of such
Triggering Event, such assumption shall be in addition to, and shall not release
the Issuer from,  any  continuing  obligations of the Issuer under this Warrant)
and (B) the obligation to deliver to such Holder such shares of Securities, cash
or property as, in accordance  with the foregoing  provisions of this subsection
(a),  such  Holder  shall be entitled  to  receive,  and such Person  shall have
similarly delivered to such Holder an opinion of counsel for such Person,  which
counsel  shall be  reasonably  satisfactory  to such  Holder,  stating that this
Warrant shall thereafter  continue in full force and effect and the terms hereof
(including,  without  limitation,  all of the provisions of this subsection (a))
shall be applicable to the Securities, cash or property which such Person may be
required to deliver  upon any  exercise of this  Warrant or the  exercise of any
rights pursuant hereto.



                                        6

         (iii) If with  respect  to any  Triggering  Event,  the  Holder of this
Warrant has exercised its right as provided in clause (y) of subparagraph (i) of
this subsection (a) to sell this Warrant or a portion thereof, the Issuer agrees
that as a condition to the  consummation of any such Triggering Event the Issuer
shall secure such right of Holder to sell this Warrant to the Person  continuing
after or  surviving  such  Triggering  Event and the Issuer shall not effect any
such  Triggering  Event  unless  upon or prior to the  consummation  thereof the
amounts of cash,  property and/or Securities  required under such clause (y) are
delivered to the Holder of this Warrant.  The obligation of the Issuer to secure
such right of the Holder to sell this Warrant  shall be subject to such Holder's
cooperation  with the  Issuer,  including,  without  limitation,  the  giving of
customary representations and warranties to the purchaser in connection with any
such sale.  Prior notice of any Triggering Event shall be given to the Holder of
this Warrant in accordance with Section 11 hereof.

         (b)  SUBDIVISION OR COMBINATION OF SHARES.  If the Issuer,  at any time
while this  Warrant is  outstanding,  shall  subdivide  or combine any shares of
Common Stock,  (i) in case of subdivision of shares,  the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer  shall take a record of Holders of its Common Stock for the purpose of so
subdividing,  as at the applicable record date, whichever is earlier) to reflect
the  increase in the total  number of shares of Common  Stock  outstanding  as a
result of such subdivision,  or (ii) in the case of a combination of shares, the
Warrant Price shall be  proportionately  increased (as at the effective  date of
such  combination or, if the Issuer shall take a record of Holders of its Common
Stock  for the  purpose  of so  combining,  as at the  applicable  record  date,
whichever is earlier) to reflect the  reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

         (c) CERTAIN  DIVIDENDS AND  DISTRIBUTIONS.  If the Issuer,  at any time
while this Warrant is outstanding, shall:

                  (i)  STOCK  DIVIDENDS.  Pay a  dividend  in, or make any other
         distribution to its stockholders (without  consideration  therefor) of,
         shares of Common Stock, the Warrant Price shall be adjusted,  as at the
         date the  Issuer  shall take a record of the  Holders  of the  Issuer's
         Capital  Stock for the  purpose of  receiving  such  dividend  or other
         distribution  (or if no such  record is  taken,  as at the date of such
         payment or other distribution), to that price determined by multiplying
         the Warrant Price in effect  immediately  prior to such record date (or
         if no such record is taken,  then immediately  prior to such payment or
         other distribution),  by a fraction (1) the numerator of which shall be
         the total  number of shares  of Common  Stock  outstanding  immediately
         prior to such  dividend or  distribution,  and (2) the  denominator  of
         which shall be the total number of shares of Common  Stock  outstanding
         immediately after such dividend or distribution (plus in the event that
         the Issuer paid cash for  fractional  shares,  the number of additional
         shares  which  would  have  been  outstanding  had  the  Issuer  issued
         fractional shares in connection with said dividends); or



                                        7

<PAGE>


                  (ii)  OTHER  DIVIDENDS.   Pay  a  dividend  on,  or  make  any
         distribution of its assets upon or with respect to (including,  but not
         limited to, a distribution of its property as a dividend in liquidation
         or  partial  liquidation  or by way of return of  capital),  the Common
         Stock (other than as described in clause (i) of this  subsection  (c)),
         or in the event  that the  Company  shall  offer  options  or rights to
         subscribe  for  shares  of Common  Stock,  or issue  any  Common  Stock
         Equivalents,  to all of its holders of Common Stock, then on the record
         date for such  payment,  distribution  or offer or, in the absence of a
         record date, on the date of such payment,  distribution  or offer,  the
         Holder  shall  receive  what the  Holder  would  have  received  had it
         exercised this Warrant in full immediately  prior to the record date of
         such  payment,  distribution  or offer or, in the  absence  of a record
         date,  immediately  prior to the date of such payment,  distribution or
         offer.

         (d) ISSUANCE OF ADDITIONAL  SHARES OF COMMON STOCK.  If the Issuer,  at
any time while this Warrant is outstanding, shall issue any Additional Shares of
Common  Stock  (otherwise  than as provided  in the  foregoing  subsections  (a)
through (c) of this Section 4), at a price per share less than the Warrant Price
then in effect or less than the Per Share Market Value then in effect or without
consideration,  then the Warrant Price upon each such issuance shall be adjusted
to that price  (rounded to the  nearest  cent)  determined  by  multiplying  the
Warrant Price then in effect by a fraction:

                  (i) the  numerator  of which  shall be equal to the sum of (A)
         the number of shares of Common Stock  outstanding  immediately prior to
         the  issuance of such  Additional  Shares of Common  Stock plus (B) the
         number of shares of Common Stock  (rounded to the nearest  whole share)
         which  the  aggregate  consideration  for  the  total  number  of  such
         Additional  Shares of Common Stock so issued would  purchase at a price
         per share  equal to the greater of the Per Share  Market  Value then in
         effect and the Warrant Price then in effect, and

                  (ii) the  denominator of which shall be equal to the number of
         shares of Common Stock  outstanding  immediately  after the issuance of
         such Additional Shares of Common Stock.

The  provisions  of  this  subsection  (d)  shall  not  apply  under  any of the
circumstances for which an adjustment is provided in subsections (a), (b) or (c)
of this Section 4. No  adjustment  of the Warrant Price shall be made under this
subsection (d) upon the issuance of any Additional  Shares of Common Stock which
are issued pursuant to any Common Stock  Equivalent if upon the issuance of such
Common Stock  Equivalent  (x) any  adjustment  shall have been made  pursuant to
subsection (e) of this Section 4 or (Y) no adjustment  was required  pursuant to
subsection  (e) of this Section 4. No  adjustment  of the Warrant Price shall be
made under this  subsection  (d) in an amount less than $.01 per share,  but any
such lesser  adjustment  shall be carried  forward and shall be made at the time
and together with the next  subsequent  adjustment,  if any, which together with
any  adjustments  so  carried  forward  shall  amount to $.01 per share or more,
provided  that  upon any  adjustment  of the  Warrant  Price as a result  of any
dividend or distribution payable in


                                        8

<PAGE>


Common Stock or Convertible  Securities or the reclassification,  subdivision or
combination  of Common  Stock into a greater or  smaller  number of shares,  the
foregoing  figure of $.01 per share (or such figure as last  adjusted)  shall be
adjusted (to the nearest  one-half  cent) in proportion to the adjustment in the
Warrant Price.

         (e) ISSUANCE OF COMMON STOCK  EQUIVALENTS.  If the Issuer,  at any time
while this Warrant is outstanding,  shall issue any Common Stock  Equivalent and
the price per share for which Additional  Shares of Common Stock may be issuable
thereafter  pursuant  to such  Common  Stock  Equivalent  shall be less than the
Warrant  Price  then in effect or less than the Per Share  Market  Value then in
effect,  or if, after any such issuance of Common Stock  Equivalents,  the price
per share for which Additional Shares of Common Stock may be issuable thereafter
is amended  or  adjusted,  and such  price as so amended  shall be less than the
Warrant  Price or less than the Per Share  Market Value in effect at the time of
such  amendment,  then the Warrant  Price upon each such  issuance or  amendment
shall be adjusted as provided in the first  sentence of  subsection  (d) of this
Section 4 on the basis  that (1) the  maximum  number  of  Additional  Shares of
Common Stock  issuable  pursuant to all such Common Stock  Equivalents  shall be
deemed to have been issued  (whether or not such Common  Stock  Equivalents  are
actually then  exercisable,  convertible or exchangeable in whole or in part) as
of the  earlier  of (A) the date on which the  Issuer  shall  enter  into a firm
contract for the issuance of such Common  Stock  Equivalent,  or (B) the date of
actual  issuance  of  such  Common  Stock  Equivalent,  and  (2)  the  aggregate
consideration for such maximum number of Additional Shares of Common Stock shall
be deemed to be the minimum  consideration  received or receivable by the Issuer
for the  issuance of such  Additional  Shares of Common  Stock  pursuant to such
Common Stock Equivalent.  No adjustment of the Warrant Price shall be made under
this  subsection  (e) upon the  issuance of any  Convertible  Security  which is
issued  pursuant  to the  exercise  of any  warrants  or other  subscription  or
purchase rights  therefor,  if any adjustment shall previously have been made in
the  Warrant  Price then in effect upon the  issuance of such  warrants or other
rights  pursuant to this subsection (e). If no adjustment is required under this
subsection  (e)  upon  issuance  of any  Common  Stock  Equivalent  or  once  an
adjustment  is made under this  subsection  (e) based upon the Per Share  Market
Value in effect on the date of such adjustment,  no further  adjustment shall be
made  under  this  subsection  (e) based  solely  upon a change in the Per Share
Market Value after such date.

         (f) PURCHASE OF COMMON  STOCK BY THE ISSUER.  If the Issuer at any time
while this  Warrant is  outstanding  shall,  directly  or  indirectly  through a
Subsidiary or  otherwise,  purchase,  redeem or otherwise  acquire any shares of
Common  Stock at a price per share  greater than the Per Share Market Value then
in  effect,  then the  Warrant  Price  upon each such  purchase,  redemption  or
acquisition  shall be  adjusted to that price  determined  by  multiplying  such
Warrant  Price by a fraction  (i) the  numerator of which shall be the number of
shares  of  Common  Stock  outstanding   immediately  prior  to  such  purchase,
redemption or  acquisition  minus the number of shares of Common Stock which the
aggregate  consideration  for the total number of such shares of Common Stock so
purchased,  redeemed or acquired  would  purchase at the Per Share Market Value;
and (ii) the denominator of which shall be the number of shares of Common Stock


                                        9

<PAGE>


outstanding immediately after such purchase,  redemption or acquisition. For the
purposes of this subsection (f), the date as of which the Per Share Market Value
shall be computed shall be the earlier of (x) the date on which the Issuer shall
enter into a firm contract for the purchase,  redemption or  acquisition of such
Common Stock, or (y) the date of actual  purchase,  redemption or acquisition of
such  Common  Stock.  For the  purposes  of this  subsection  (f),  a  purchase,
redemption or acquisition of a Common Stock  Equivalent  shall be deemed to be a
purchase of the underlying  Common Stock,  and the  computation  herein required
shall be made on the basis of the full exercise,  conversion or exchange of such
Common Stock  Equivalent  on the date as of which such  computation  is required
hereby to be made,  whether or not such  Common  Stock  Equivalent  is  actually
exercisable, convertible or exchangeable on such date.

         (g) OTHER  PROVISIONS  APPLICABLE TO ADJUSTMENTS  UNDER THIS SECTION 4.
The following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

                  (i) COMPUTATION OF CONSIDERATION.  The consideration  received
         by the Issuer shall be deemed to be the  following:  to the extent that
         any Additional  Shares of Common Stock or any Common Stock  Equivalents
         shall be issued for a cash consideration, the consideration received by
         the Issuer  therefor,  or if such Additional  Shares of Common Stock or
         Common Stock  Equivalents  are offered by the Issuer for  subscription,
         the subscription  price, or, if such Additional  Shares of Common Stock
         or Common Stock  Equivalents  are sold to  underwriters  or dealers for
         public offering  without a subscription  offering,  the public offering
         price,  in any such case  excluding any amounts paid or receivable  for
         accrued  interest or accrued  dividends  and without  deduction  of any
         compensation,  discounts,  commissions, or expenses paid or incurred by
         the  Issuer  for or in  connection  with the  underwriting  thereof  or
         otherwise in connection with the issue thereof; to the extent that such
         issuance shall be for a consideration  other than cash, then, except as
         herein  otherwise  expressly  provided,  the fair market  value of such
         consideration at the, time of such issuance as determined in good faith
         by the Board.  The  consideration  for any Additional  Shares of Common
         Stock issuable  pursuant to any Common Stock  Equivalents  shall be the
         consideration  received  by the Issuer for issuing  such  Common  Stock
         Equivalents,  plus the additional  consideration  payable to the Issuer
         upon  the  exercise,  conversion  or  exchange  of  such  Common  Stock
         Equivalents.  In case of the  issuance  at any  time of any  Additional
         Shares of Common  Stock or  Common  Stock  Equivalents  in  payment  or
         satisfaction  of any  dividend  upon any class of Capital  Stock of the
         Issuer  other than  Common  Stock,  the Issuer  shall be deemed to have
         received  for such  Additional  Shares of Common  Stock or Common Stock
         Equivalents  a  consideration  equal to the amount of such  dividend so
         paid  or  satisfied.  In any  case in  which  the  consideration  to be
         received or paid shall be other than cash,  the Board shall  notify the
         Holder of this Warrant of its determination of the fair market value of
         such consideration  prior to payment or accepting receipt thereof.  If,
         within thirty days after receipt of said notice,  the Majority  Holders
         shall  notify  the  Board  in  writing  of  their   objection  to  such
         determination,  a  determination  of the  fair  market  value  of  such
         consideration shall be


                                       10

<PAGE>


         made by an Independent  Appraiser selected by the Majority Holders with
         the approval of the Board  (which  approval  shall not be  unreasonably
         withheld), whose fees and expenses shall be paid by the Issuer.

                  (ii)  READJUSTMENT  OF WARRANT  PRICE.  Upon the expiration or
         termination  of the right to convert,  exchange or exercise  any Common
         Stock  Equivalent  the issuance of which  effected an adjustment in the
         Warrant  Price,  if such Common  Stock  Equivalent  shall not have been
         converted, exercised or exchanged in its entirety, the number of shares
         of Common  Stock deemed to be issued and  outstanding  by reason of the
         fact that they were issuable upon  conversion,  exchange or exercise of
         any such  Common  Stock  Equivalent  shall no longer be computed as set
         forth above,  and the Warrant Price shall  forthwith be readjusted  and
         thereafter  be the price which it would have been (but  reflecting  any
         other  adjustments in the Warrant Price made pursuant to the provisions
         of this Section 4 after the  issuance of such Common Stock  Equivalent)
         had the  adjustment of the Warrant  Price been made in accordance  with
         the issuance or sale of the number of Additional Shares of Common Stock
         actually  issued upon  conversion,  exchange or issuance of such Common
         Stock Equivalent and thereupon only the number of Additional  Shares of
         Common Stock actually so issued shall be deemed to have been issued and
         only the consideration  actually received by the Issuer (computed as in
         clause  (i) of this  subsection  (g))  shall  be  deemed  to have  been
         received by the Issuer.

                  (iii) OUTSTANDING COMMON STOCK. The number of shares of Common
         Stock at any time outstanding  shall (A) not include any shares thereof
         then directly or indirectly  owned or held by or for the account of the
         Issuer or any of its  Subsidiaries,  and (B) be deemed to  include  all
         shares of Common  Stock then  issuable  upon  conversion,  exercise  or
         exchange of any then outstanding  Common Stock Equivalents or any other
         evidences of Indebtedness,  shares of Capital Stock or other Securities
         which are or may be at any time  convertible  into or exchangeable  for
         shares of Common Stock or Other Common Stock.

         (h) OTHER ACTION  AFFECTING  COMMON  STOCK.  In case after the Original
Issue Date the Issuer shall take any action  affecting its Common  Stock,  other
than an action described in any of the foregoing  subsections (a) through (g) of
this  Section 4,  inclusive,  and the failure to make any  adjustment  would not
fairly  protect the purchase  rights  represented  by this Warrant in accordance
with the  essential  intent and  principle  of this  Section 4, then the Warrant
Price shall be adjusted in such manner and at such time as the Board may in good
faith determine to be equitable in the circumstances.

         (i)  ADJUSTMENT OF WARRANT SHARE  NUMBER.  Upon each  adjustment in the
Warrant Price pursuant to any of the foregoing provisions of this Section 4, the
Warrant Share Number shall be adjusted,  to the nearest one hundredth of a whole
share,  to  the  product  obtained  by  multiplying  the  Warrant  Share  Number
immediately  prior to such  adjustment in the Warrant  Price by a fraction,  the
numerator of which shall be the Warrant Price immediately before giving


                                       11

<PAGE>


effect to such  adjustment  and the  denominator  of which  shall be the Warrant
Price immediately after giving effect to such adjustment. If the Issuer shall be
in default  under any  provision  contained in Section 3 of this Warrant so that
shares  issued at the Warrant Price  adjusted in accordance  with this Section 4
would not be validly issued, the adjustment of the Warrant Share Number provided
for in the foregoing  sentence shall  nonetheless be made and the Holder of this
Warrant  shall be  entitled  to purchase  such  greater  number of shares at the
lowest price at which such shares may then be validly  issued  under  applicable
law. Such exercise  shall not  constitute a waiver of any claim arising  against
the Issuer by reason of its default under Section 3 of this Warrant.

         (j) FORM OF WARRANT  AFTER  ADJUSTMENTS.  The form of this Warrant need
not be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

         5. NOTICE OF  ADJUSTMENTS.  Whenever the Warrant Price or Warrant Share
Number  shall be adjusted  pursuant  to Section 4 hereof  (for  purposes of this
Section 5, each an  "adjustment"),  the Issuer  shall cause its Chief  Financial
Officer to prepare  and  execute a  certificate  setting  forth,  in  reasonable
detail,  the event requiring the adjustment,  the amount of the adjustment,  the
method by which such  adjustment was calculated  (including a description of the
basis on which the Board  made any  determination  hereunder),  and the  Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such  certificate  to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with  respect to the matters set forth in such  certificate  may at
the option of the Holder of this  Warrant be  submitted  to one of the  national
accounting  firms  currently  known as the "big five"  selected  by the  Holder,
provided  that the Issuer shall have ten days after  receipt of notice from such
Holder  of its  selection  of such firm to object  thereto,  in which  case such
Holder shall select another such firm and the Issuer shall have no such right of
objection.  The firm  selected by the Holder of this  Warrant as provided in the
preceding  sentence shall be instructed to deliver a written  opinion as to such
matters to the Issuer and such Holder within thirty days after  submission to it
of such dispute.  Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

         6.  WARRANT  CALL.  At any time  after the  Registration  Statement  is
declared  effective,  the Issuer, at its option,  may call upon 30 calendar days
written  notice to the Holder  (the "Call  Notice")  25% of the  Warrants if the
Common Stock of the Issuer  trades at a price equal to or greater than $3.00 per
share for 20 consecutive Trading Days prior to the date of the Call Notice.

         7.  FRACTIONAL  SHARES.  No fractional  shares of Warrant Stock will be
issued in connection  with and exercise  hereof,  but in lieu of such fractional
shares,  the Issuer  shall make a cash payment  therefor  equal in amount to the
product of the applicable fraction multiplied by the Per Share Market Value then
in effect.
