            2.  EXERCISE OF WARRANT,  SHARES  ISSUABLE UPON EXERCISE AND PAYMENT
FOR WARRANT SHARES.

            (a) The rights  represented  by this Warrant may be exercised at any
      time on or after the  Effective  Date and from  time to time  prior to the
      Expiration  Date, by the holder of this Warrant,  in whole or in part (but
      not as to less than 100  Warrant  Shares or as to any  fractional  Warrant
      Share), by: (i) delivery to the Company of a completed  Subscription Form;
      (ii) surrender to the Company of this Warrant;  and (iii) payment for such
      Warrant shares as provided in Section 2(b) below, at the Company's  office
      or agency in Nashua, New Hampshire,  or such other office or agency of the
      Company as the  Company may  designate  by notice in writing to the holder
      hereof.

            (b) The aggregate  purchase price for Warrant Shares being purchased
      hereunder may be paid either (i) by cash or wire  transfer of  immediately
      available  funds, or (ii) by surrender of a number of Warrant Shares which
      have a fair market  value  equal to the  aggregate  purchase  price of the
      Warrant Shares being purchased ("NET ISSUANCE") as determined  herein.  If
      the Holder  elects the Net Issuance  method of payment,  the Company shall
      issue to  Holder  upon  exercise  a number of  shares  of  Warrant  Shares
      determined in accordance with the following formula:

                                     Y(A-B)
                                  X= ------
                                       A

            where: X = the number of Warrant Shares to be issued to the Holder;

<PAGE>

            Y = the number of Warrant Shares with respect to which the Holder is
                exercising its purchase rights under this Warrant;

            A = the fair market value of one share of the Warrant  Shares on the
                date of exercise; and

            B = the Applicable Purchase Price.

No fractional shares arising out of the above formula for determining the number
of shares to be issued to the Holder shall be issued,  and the Company  shall in
lieu thereof  make payment to the Holder of cash in the amount of such  fraction
multiplied  by the fair market  value of one share of the Warrant  Shares on the
date of exercise.  For purposes of the above calculation,  the fair market value
of one share of the  Warrant  Shares  shall mean (a) if the date of  exercise is
after  the  commencement  of  trading  of the  Preferred  Stock on a  securities
exchange or over-the-counter  but prior to the closing of the IPO, the price per
share to the  public  set forth on the  final  prospectus  relating  to the IPO,
multiplied  by the number of shares of Preferred  Stock into which each share of
the  Warrant  Shares is then  convertible,  (b) if the  Preferred  Stock is then
traded on a  securities  exchange,  the  average of the  closing  prices of such
Preferred  Stock on such  exchange  over the 30 calendar  day period (or portion
thereof)  ending  three days prior to the date of  exercise,  multiplied  by the
number of shares of Preferred  Stock into which each share of the Warrant Shares
is  then  convertible,  (c) if the  Preferred  Stock  is then  regularly  traded
over-the-counter,  the average of the closing  sale  prices or  secondarily  the
closing bid of such Preferred  Stock over the 30 calendar day period (or portion
thereof)  ending  three days prior to the date of  exercise,  multiplied  by the
number of shares of Preferred  Stock into which each share of the Warrant Shares
is  then  convertible,  or (d) if  there  is no  active  public  market  for the
Preferred  Stock,  the fair market value  thereof as determined in good faith by
the Board of  Directors of the  Company,  multiplied  by the number of shares of
Preferred Stock into which each share of the Warrant Shares is then convertible.

            (c) The Company agrees and  acknowledges  that the Warrant Shares so
      purchased  shall be deemed to be issued to the  holder of this  Warrant as
      the record owner of such shares as of the close of business on the date on
      which this Warrant and the  Subscription  Form shall have been surrendered
      and payment made for such shares as aforesaid.  Upon receipt thereof,  the
      Company shall, as promptly as  practicable,  and in any event within seven
      business days  thereafter,  execute or cause to be executed and deliver to
      the holder of this Warrant a certificate or certificates  representing the
      aggregate  number of Warrant Shares specified in said  Subscription  Form.
      Each stock  certificate so delivered shall be in such  denomination as may
      be required by the holder of this Warrant and shall be  registered  in the
      name of the  holder  of this  Warrant.  If this  Warrant  shall  have been
      exercised only in part, the Company shall, at the time of delivery of said
      stock  certificate or  certificates,  deliver to the  Warrantholder  a new
      Warrant  evidencing  the rights of such holder to purchase  the  remaining
      Warrant  Shares  covered  by  this  Warrant.  The  Company  shall  pay all
      expenses,  stock  transfer  taxes and other charges  payable in connection
      with  the  preparation,  execution  and  delivery  of  stock  certificates
      pursuant to this Section 2.

            3. OWNERSHIP AND TRANSFER OF THIS WARRANT.

            (a) The Company may deem and treat the registered of this Warrant as
      the holder and owner hereof (notwithstanding any notations of ownership or
      writing made hereon by anyone other than the Company) for all purposes and
      shall not be affected by any notice to the contrary, until presentation of
      this  Warrant  for  transfer  as  provided  herein  and then  only if such
      transfer  meets the  requirements  of Sections 3 and 5 hereof.  All shares
      issuable pursuant to this Warrant, and all shares of Common Stock issuable
      upon conversion thereof,  shall be deemed to be "Registerable  Securities"
      for purposes of the Second Amended and Restated  Investor Rights Agreement
      dated as of February 13, 2003,  among the Company and the  stockholders of
      the Company named therein.

            (b) An  appropriate  legend may be endorsed on the  Warrants and the
      certificates    representing   the   Warrant   Shares   evidencing   these
      restrictions,  and a stop  order may be placed on the  Company's  transfer
      records.

            4. EXCHANGE,  TRANSFER OR REPLACEMENT.  Subject to Section 5 hereof,
this  Warrant is  exchangeable  upon the  surrender  hereof by the holder to the
Company at its office or agency  described  in Section 2 hereof for new Warrants
of like tenor and date  representing  in the aggregate the right to purchase the
number of shares of Series Preferred Stock purchasable  hereunder,  each of such
new  Warrants to represent  the right to purchase  such number of shares (not to
exceed the aggregate total number purchasable  hereunder) as shall be designated
by the Warrantholder at the time of such surrender. Subject to Section 5 hereof,
this Warrant and all rights  hereunder  are  transferable,  in whole or in part,
upon the books of the  Company  by the  holder  in person or by duly  authorized
attorney,  and a new  Warrant  of the same tenor and date as this  Warrant,  but
registered in the name of the transferee, shall be executed and delivered by the
Company upon surrender of this Warrant,  duly endorsed, at said office or agency
of the Company. Upon receipt by the Company of evidence reasonably  satisfactory
to it of the loss, theft,  destruction,  or mutilation of this Warrant,  and, in
case of loss,  theft,  or  destruction,  of  indemnity  or  security  reasonably
satisfactory  to it, and upon  surrender and  cancellation  of this Warrant,  if
mutilated,  the Company  will make and  deliver a new Warrant of like tenor,  in
lieu of this  Warrant.  This Warrant  shall be promptly  canceled by the Company
upon the  surrender  hereof  in  connection  with  any  exchange,  transfer,  or
replacement.  The Company  shall pay all  expenses,  transfer  taxes,  and other
charges payable in connection with the preparation,  execution,  and delivery of
Warrants pursuant to this Section 4.

            5. INVESTMENT  INTENT.  The Warrant Shares issuable upon exercise of
the  Warrant  and any shares of Common  Stock into which any such  shares may be
convertible  have not been registered under the Securities Act or any applicable
state law. The Warrant is issued to the  Warrantholder on the condition that the
Warrant and any Warrant  Shares  purchased  upon exercise of the Warrant and any
Common Stock into which any such shares may be converted  (excepting  shares for
which a Notification  under  Regulation A or a  Registration  Statement has been
filed  and  declared  effective  and for which  such  exercise  may be  effected
pursuant to registration or an exemption from registration  under any applicable
state law) are or will be  purchased  for  investment  purposes  and not with an
intent to distribute the same.  Prior to making any disposition of this Warrant,
the holder  shall give  written  notice to the  Company  describing  briefly the
manner of any such  proposed  disposition.  The  holder  shall not make any such

<PAGE>

disposition,  until and unless (i) such  holder has  delivered  to the Company a
legal  opinion  of  counsel,   reasonably   acceptable  to  the  Company,   that
registration  under  the  Securities  Act and any  applicable  state  law is not
required  with  respect  to  such  disposition,  or  (ii) a  Notification  under
Regulation A or a Registration  Statement covering the proposed distribution has
been filed by the Company and has become  effective  and  applicable  state laws
relating to registration  are complied with. Upon receipt of written notice form
the holder with respect to such proposed distribution,  the Company will use its
best efforts, in consultation with the holder's counsel, to ascertain as soon as
practicable whether or not registration is required,  and will advise the holder
promptly with respect thereto.

            6.  ADJUSTMENT  OF PURCHASE  PRICE.  The  Purchase  Price and/or the
number of Warrant Shares or Other  Securities the  Warrantholder  is entitled to
receive  hereunder  shall  be  subject  to  adjustment  from  time  to  time  as
hereinafter provided.

            (a) STOCK SPLITS,  STOCK DIVIDENDS AND REVERSE  SPLITS.  In case the
      Company  shall at any time  divide  the  outstanding  shares of its Series
      Preferred  Stock into a greater  number of shares  (whether  pursuant to a
      stock split,  stock dividend or  otherwise),  the Purchase Price in effect
      immediately  prior to such division shall be  proportionately  reduced and
      the number of  Warrant  Shares  shall be  proportionately  increased,  and
      conversely,  in the case the  outstanding  shares of the Company's  Series
      Preferred  Stock shall be combined  into a smaller  number of shares,  the
      Purchase Price in effect  immediately  prior to such combination  shall be
      proportionately increased and the number of Warrant Shares proportionately
      reduced.

            (b) REORGANIZATION,  CONSOLIDATION, MERGER OR SALE OF ASSETS. If any
      capital  reorganization  or  reclassification  of the capital stock of the
      Company,   or   consolidation  or  merger  of  the  Company  with  another
      corporation,  or the sale of all or  substantially  all of its  assets  to
      another corporation shall be effected in such a way that holders of shares
      of the  Company's  Series  Preferred  Stock  shall be  entitled to receive
      stock,  securities  or assets,  with  respect to or in  exchange  for such
      shares,  then,  as a condition of such  reorganization,  reclassification,
      consolidation,  merger or sale,  the holder of this Warrant shall have the
      right to  purchase  and  receive  upon the  basis  and upon the  terms and
      conditions  specified in this Warrant and in addition to or in lieu of, as
      the  case  may be,  the  shares  of  Series  Preferred  Stock  immediately
      theretofore  purchasable  and  receivable  upon the exercise of the rights
      represented  hereby,  such shares of stock,  other securities or assets as
      would have been issued or  delivered to the holder of this Warrant if such
      holder had  exercised  this Warrant and had received such shares of Series
      Preferred   Stock   prior   to  such   reorganization,   reclassification,
      consolidation,  merger or sale.  The  Company  shall not  effect  any such
      consolidation,  merger or sale,  unless prior to the consummation  thereof
      the successor  corporation (if other than the Company) resulting from such
      consolidation  or merger or the  corporation  purchasing such assets shall
      assume by written instrument  executed and mailed to the registered holder
      of this Warrant at the last address of such holder  appearing on the books
      of the  Company  the  obligation  to deliver to such holder such shares of
      stock,   securities  or  assets  as,  in  accordance  with  the  foregoing
      provisions, such holder may be entitled to purchase.

<PAGE>

            (c) OTHER ACTIONS.  The issuance of additional  capital stock of the
      Company to persons other than the  Warrantholder in a manner not discussed
      in this Section 6 shall not result in any adjustment in the Purchase Price
      or increase in the number of shares subject to this Warrant.

            (d) NOTICE.  Upon any adjustment of the Applicable Purchase Price or
      change in the number of Warrant Shares or Other Securities subject to this
      Warrant,  the Company shall give written  notice  thereof,  by first class
      mail,  postage prepaid,  addressed to the registered holder at the address
      of such holder as shown on the books of the  Company,  which  notice shall
      state the Applicable Purchase Price resulting from such adjustment and the
      increase or  decrease,  if any,  in the number of Warrant  Shares or Other
      Securities  purchasable  at such price upon the exercise of this  Warrant,
      setting forth in reasonable detail the method of calculation and the facts
      upon which such calculation is based.

            (e) OTHER NOTICES. If at any time:

                  (1) the  Company  shall  declare  any cash  dividend  upon its
Preferred Stock;

                  (2)   there   shall   be   any   capital   reorganization   or
reclassification of the capital stock of the Company; or consolidation or merger
of the  Company  with,  or sale of all or  substantially  all of its  assets to,
another corporation;

                  (3) there shall be a  voluntary  or  involuntary  dissolution,
liquidation or winding-up of the Company; or

                  (4) there shall be an IPO;

then,  in any one or more of said cases,  the Company shall give, by first class
mail, postage prepaid, addressed to the Holder of this Warrant at the address of
such  Holder as shown on the books of the  Company,  (a) at least 20 days  prior
written  notice of the date on which the books of the  Company  shall close or a
record  shall be taken for such  dividend or for  determining  rights to vote in
respect of any such  reorganization,  reclassification,  consolidation,  merger,
sale,  dissolution,  liquidation or winding-up,  and (b) in the case of any such
reorganization,  reclassification,  consolidation,  merger,  sale,  dissolution,
liquidation,  winding-up  or public  offering,  at least 20 days  prior  written
notice of the date when the same shall take place;  provided,  however, that the
Holder shall make a best  efforts  attempt to respond to such notice as early as
possible  after the receipt  thereof.  Any notice given in  accordance  with the
foregoing clause (a) shall also specify,  in the case of any such dividend,  the

notice given in accordance with the foregoing  clause (b) shall also specify the
date on which the holders of Preferred Stock shall be entitled to exchange their
Preferred  Stock  for  securities  or  other  property   deliverable  upon  such
reorganization,  reclassification,  consolidation,  merger,  sale,  dissolution,
liquidation, winding-up, conversion or public offering, as the case may be.

agrees that it will:

<PAGE>

            (a)  reserve  and  set  apart  and  have  at all  times,  free  from

      number of shares of Common Stock into which such Preferred  Stock shall be
      convertible,  and it will have at all times any other rights or privileges
      provided for herein  sufficient to enable it at any time to fulfill all of
      its obligations hereunder; and

            10.  GOVERNING LAW. This Warrant shall be governed by, and construed

Financial  Statements  are correct and complete and fairly present the financial
position of the Company at the dates  thereof and the results of  operations  of
the Company, for the periods covered thereby,  subject in the case of statements

Budget to Lender which was prepared by the Company based upon the best available
information and in good faith.

or, in the aggregate,  which has materially adversely affected,  or is likely to
materially  adversely  affect,  the  Company's  business   operations,   assets,
condition (financial or otherwise), liabilities, earnings, results of operations
or prospects;  (ii) no employee or consultant of the Company,  the loss of whose
services could  materially  and adversely  affect the Company or the business or
prospects of the Company,  taken as a whole, has left the employ of the Company,
has given any indication that he or she intends to do so or is considering doing
so, or is being terminated, (iii) there has been no damage, destruction or loss,
whether or not covered by  insurance,  materially  and  adversely  affecting the
properties or business of the Company,  taken as a whole, (iv) there has been no
waiver by the Company of a valuable  right or of a material debt owed to it, (v)
there has been no loan made by the Company to any employee,  officer or director
other than  advances of expenses made in the ordinary  course of business,  (vi)
there has been no declaration  or payment of any dividend or other  distribution

                                                                  DEBT AGREEMENT
                                                                          Page 8

course of business,  or mortgage or pledge of or  imposition  of lien on, any of
the Company's assets.

      3.11  EXEMPT  TRANSACTIONS.  Subject  to  the  accuracy  of  the  Lender's
representations in Section 4 hereof, the offer,  issuance,  sale and delivery of
the Warrant(s) and the Warrant Shares pursuant to this Agreement are exempt from
the  registration  requirements  of the Securities Act and the  registration  or
qualification  requirements of the State of Delaware and neither the Company nor
anyone acting on its behalf will take any action  hereafter that would cause the
loss of such exemption.

      3.12 TAX RETURNS AND AUDITS.

            (A) All required federal, state and local tax returns of the Company
have been accurately prepared and duly and timely filed, and all federal,  state
and local taxes required to be paid with respect to the periods  covered by such
returns have been paid. No deficiency  assessment or proposed  adjustment of the
Company's  United  States  income tax or state or  municipal  taxes is  pending,
except as  disclosed  on the  Company's  books and records as  furnished  to the
Lender  and its  counsel,  and the  Company  has no  knowledge  of any  proposed
liability  for any tax to be imposed upon its income,  properties  or assets for
which  there  is not  adequate  reserve  reflected  in the  unaudited  Financial
Statements.

            (B) PAYMENT OF TAXES. The Company has accurately  prepared and filed
within the time  prescribed by law all federal,  state and local income,  excise

filed by it and has paid or made provision for the payment of all taxes shown to
be due  thereon  and  adequate  provision  has been made for all taxes and other
charges  to which the  Company is subject  and which are not  currently  due and
payable.  The federal income tax returns of the Company have never been examined
by the Internal  Revenue  Service.  Neither the Internal Revenue Service nor any
other taxing authority is now asserting or, to the best of Company's  knowledge,
is  threatening  to assert  against the  Company,  any  deficiency  or claim for
additional taxes or interest thereon or penalties in connection  therewith,  and
the Company does not know of any basis for any such deficiency or claim.

      3.13 LABOR AGREEMENTS AND ACTIONS.  The Company is not bound by or subject
to any  contract,  commitment or  arrangement  with any labor union and no labor
union has requested or, to the knowledge of the Company, sought to represent any
of the employees,  representatives or agents of the Company.  There is no strike
or other labor dispute involving the Company pending or, to the knowledge of the
Company, threatened, nor is the Company aware of any labor organization activity
involving the employees of the Company.

      3.14 INSURANCE COVERAGE.  There are, in full force,  policies of insurance
issued by insurers of  recognized  responsibility  insuring the  Company,  their
properties and business against such losses and risks and in such amounts as are
adequate for their business and proposed  business and customary among companies
engaged in the same or similar businesses.

      3.15 INTEREST IN COMPETITORS.  Neither the Company nor any of its officers
or directors has any interest, either by way of contract or by way of investment
(other  than as  holder  of not

the best of the Company's  knowledge,  no material  expenditures  are or will be
required in order to comply with any such existing statute, law or regulation.

      3.17 DISCLOSURE.  The Company has provided Lender with all the information
it has  requested  for  deciding  whether  to  purchase  the  Debenture  and all
information  which the Company  believes is reasonably  necessary to make such a
decision.  Neither this Purchase Agreement (including all schedules and exhibits
hereto),  nor any  other  written  statements,  certificates  or  other  written
information  delivered  pursuant to, or in  connection  with,  the  transactions
contemplated hereby contains any untrue statement of a material fact or omits to
state a material  fact  necessary to make the  statements  herein or therein not
misleading.  To the  best of the  Company's  knowledge,  there  is no fact  that
materially adversely affects the business,  projections,  condition,  affairs or
operations  of  the  Company,  taken  as a  whole,  or any of  either  of  their
properties  or  assets  that  has not been set  forth in this  Agreement  or the

all material obligations, agreements and conditions contained in any evidence of
indebtedness  or any loan agreement or other  contract or agreement  (whether or
not relating to indebtedness) of the Company,  the lack of compliance with which

terminate  any material  right or  agreement  of the Company.  The Company is in
compliance in all respects with the provisions of its Articles and Bylaws.

      3.21  LICENSES  AND  OTHER  RIGHTS,   COMPLIANCE.   The  Company  has  all
franchises,  permits,  licenses  and other  rights and  privileges  necessary to

the time of conversion,  such Warrant Shares are registered under the Securities
Act, shall bear the following legend:

      THE SHARES  REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER

Rule 144(k) as in effect as of the date of this Agreement and,  provided further

<PAGE>

                                                                  DEBT AGREEMENT

6. EVENTS OF DEFAULT.

      6.1 EVENT OF DEFAULT DEFINED: ACCELERATION OF MATURITY; WAIVER OF DEFAULT.
In case one or more of the following  events (whatever the reason for such event
and whether it shall be voluntary or  involuntary or be effected by operation of

or  regulation  of any  administrative  or  governmental  body)  (an  "Event  of
Default") shall have occurred and be continuing:

            (A) Default in the payment of any  interest  upon the Note(s) as and

Lender;

            (C) An  involuntary  case or other  proceeding  shall  be  commenced
against the Company  seeking  liquidation,  reorganization  or other relief with
respect to it or its debts under any applicable bankruptcy,  insolvency or other
similar  law,  now or  hereafter  in effect,  or seeking  the  appointment  of a
receiver,  liquidator,  assignee,  custodian,  trustee, sequestrator (or similar
official)  of the  Company or for any  substantial  part of the  property of the
Company or the winding up or liquidation of the affairs of the Company, and such
case or proceeding  shall remain unstayed and undismissed for a period of thirty
(30) days, or an order for relief shall be entered against the Company under the
federal bankruptcy laws as now of hereafter in effect;

            (D) Company  shall  commence a voluntary  case under any  applicable
bankruptcy,  insolvency  or other  similar law,  now or hereafter in effect,  or
consent  to the entry of an order for  relief in an  involuntary  case under any
such law,  or consent to the  appointment  or taking  possession  by a receiver,
liquidator,  assignee, custodian, trustee, sequestrator (or similar official) of
the Company or for any substantial  part of the property of the Company,  or the
Company shall make any general assignment for the benefit of creditors, or shall
fail  generally  to pay its debts as they come due, or shall take any  corporate
action to authorize any of the foregoing;

            (E) Any  representation or warranty made by the Company in Section 3
hereof,  or in any of the  Transaction  Documents,  shall  prove  to  have  been
incorrect in any respect  which is  materially  adverse to the Company or Lender
when made or as of the Closing Date; or

            (F)  The  Company  shall  fail  to  observe  the  covenants  of this
Agreement,  or in any of the  Transaction  Documents,  and  such  failure  shall
continue  for twenty  (20) days after the  receipt  of written  notice  from the
holder  (except  as to  covenants  contained  in Section 5 as to which no notice
shall be required).

<PAGE>

                                                                  DEBT AGREEMENT
                                                                         Page 17

      Then,  and in each and every  such case  [other  than an Event of  Default
specified in Section 6.1(C) or (D)],  unless all of the principal  amount of the
Note(s) shall have already become due and payable, the Lender, for so long as it
holds more than fifty percent (50%) aggregate  principal  amount of the Note(s),
and  thereafter,  the  holder  of more than  fifty  percent  (50%) in  aggregate
principal  amount of the Note(s) then  outstanding,  by notice in writing to the
Company, may declare the entire principal amount of the Note(s) and the interest
accrued  thereon  to  be  due  and  payable  immediately,  and,  upon  any  such
declaration,  the same shall become immediately due and payable.  If an Event of
Default  specified in Section  6.1(C) or (D) occurs with respect to the Company,
the  principal  of, and accrued  interest  on, the Note(s)  shall  become and be
immediately  due and payable without any declaration or other act on the part of
the Lender.  Presentment,  demand, protest and all other notices of any kind are
hereby expressly waived by the Company.

      The foregoing paragraph,  however, is subject to the condition that if, at
any time after all of the  principal of the Note(s)  shall have been so declared
due and payable, and before any judgment or decree for the payment of the monies
due shall have been  obtained or entered as  hereinafter  provided,  the Company
shall pay,  or shall  deposit  in trust for the  benefit  of the  Lender,  a sum
sufficient to pay all matured  installments of interest upon the Note(s) and the
principal  of the  Note(s)  which  shall  have  become  due  otherwise  than  by
acceleration  (with interest upon such principal and, to the extent that payment
of such interest is enforceable under applicable law, on overdue installments of
interest,  at the same rate as the rate of interest specified in the Note(s), to
the date of such payment or deposit),  and if any and all Defaults and Events of
Default under this Agreement, other than the non-payment of the principal of the
Note(s)  which  shall have  become due by  acceleration,  shall have been cured,
waived or otherwise  remedied as provided herein,  then, and in every such case,
the holders of more than fifty  percent (50%) of aggregate  principal  amount of
the Note(s),  then outstanding,  by written notice to the Company, may waive all
Defaults and rescind and annul such  declaration  and its  consequences,  but no
such waiver or  rescission  and  annulment  shall  extend to or shall affect any
subsequent Default or shall impair any right consequent thereon.

      6.2  POWERS  AND  REMEDIES  CUMULATIVE;  DELAY OR  OMISSION  NOT WAIVER OF
DEFAULT.  No right or remedy herein  conferred upon or reserved to the Lender is
intended  to be  exclusive  of any other  right or remedy,  and every  right and
remedy shall,  to the extent  permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or  otherwise.  The  assertion or employment of any right or remedy
hereunder,  or  otherwise,   shall  not  prevent  the  concurrent  assertion  or
employment of any other appropriate right or remedy.

      No delay or omission of the Lender to exercise any right or power accruing
upon any Event of Default occurring and continuing as aforesaid shall impair any
such  right or power or shall be  construed  to be a waiver of any such Event of
Default or an  acquiescence  therein;  and every power and remedy  given by this
Agreement,  any Note or Warrant or by law may be exercised from time to time and
as often as shall be deemed expedient by the Lender.

7. EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF NOTE(S) OR WARRANT(S).

            (A) Upon surrender of any Note or Warrant to the Company,  or at the
office of its stock transfer  agent,  with an instrument of assignment and funds
sufficient to pay any transfer tax, the Company shall,  without charge,  execute
and deliver a new Note or Warrant in the name of the assignee or assignees named
in such  instrument of assignment  and, if such holder's  entire interest is not
being  assigned in the name of such holder,  such Note or Warrant shall promptly
be canceled.

            (B) A Note or Warrant may be divided or combined  with other Note(s)
or Warrant(s) that carry the same rights upon presentation thereof at the office
of the  Company or at the office of its stock  transfer  agent  together  with a
written notice  specifying the names and denominations in which such new Note(s)
or Warrant(s) is/are to be issued and signed by the holder thereof.

            (C) Upon  receipt by the Company of evidence  satisfactory  to it of
the loss, theft, destruction or mutilation of any Note(s) or Warrant(s), and (in
the  case  of  loss,   theft  or   destruction)   of   reasonably   satisfactory
indemnification   and  upon  surrender  and   cancellation  of  any  Note(s)  or
Warrant(s), if mutilated, the Company shall execute and deliver a new Note(s) or
Warrant(s) of like tenor and date.  Any such new Note(s) or Warrant(s)  executed
and delivered shall constitute an additional  contractual obligation on the part
of the  Company,  whether or not the  Note(s)  or  Warrant(s)  so lost,  stolen,
destroyed or mutilated shall be, at any time, enforceable by anyone.

8. LENDER'S RIGHT OF FIRST REFUSAL.

      8.1 RIGHT OF FIRST REFUSAL.

            (A) The Company hereby grants to the Lender,  for a period of thirty
(30) days, and any subsequent holder (the "Rights Holders") of the Warrants, the
right of first offer to purchase,  pro rata, a portion of "New  Securities"  (as
defined in this Section 8) that the Company may,  from time to time,  propose to
sell and issue.  Each Rights Holder's pro rata share, for purposes of this Right
of First  Refusal,  is the ratio of (X) the  number of shares of  capital  stock
owned or issuable  upon the  conversion  or exercise of any of the common  stock
owned  by  Rights  Holder  immediately  after  the  Closing  to  (Y)  the  total
Outstanding  Equity Securities of the Company;  provided,  however,  that in the
event  that any  Rights  Holder  elects  not to  purchase  its pro rata share in
accordance   with  the   above  (a   "Non-Participating   Holder"),   then  each
participating  Rights Holder  purchasing New  Securities may purchase,  on a pro
rata  basis,  based on the  common  stock held  among the  participating  Rights
Holders,  such  Non-Participating  Holder's pro rata share.  This right of first
refusal shall be subject to the following provisions.

            (B) "NEW SECURITIES" shall mean any Common Stock or other securities
(debt or equity) of the Company,  whether or not  authorized on the date hereof,
and  rights,  options  or  warrants  to  purchase  such  Common  Stock  or other
securities,  and  securities  of any type  whatsoever  that are,  or may become,
convertible into said Common Stock or Preferred Stock;  provided,  however, that
"New Securities" does not include the following:

                                                                  DEBT AGREEMENT
                                                                         Page 19

                  (i) Securities of the Company  offered to the public  pursuant
      to a bona fide Public Offering;

                  (ii)   Securities  of  the  Company  issued  pursuant  to  the
      acquisition of another  corporation by the Company by merger,  or purchase
      of  substantially  all of the assets or other  reorganization  whereby the
      Company owns not less than fifty-one  percent (51%) of the voting power of
      such other corporation; or

                  (iii)  Securities  issued in connection  with any stock split,
      stock dividend or recapitalization by the Company.

                  (iv) Options approved by the Board of Directors of the Company
      for issuance to employees or directors of the Company,  or the issuance of
      shares upon the exercise of outstanding options or warrants.

            (C) In the event that the Company  proposes to undertake an issuance
of New  Securities,  it shall  give each  Rights  Holder  written  notice of its
intention,  describing  the  type of New  Securities,  the  price,  the name and
address of the intended  purchaser  and the general terms upon which the Company
proposes to issue the same.  Each Rights  Holder shall have twenty (20) business
days  from the date of such  notice is given to agree to  purchase  its pro rata
share of such New  Securities  or any portion  thereof at the price and upon the
general terms  specified in the notice by giving  written  notice to the Company
and stating therein the quantity of New Securities to be purchased.

            (D) In the  event  that  the  Rights  Holders'  aggregate  pro  rata
exercised  portion  is less than the  amount of New  Securities  proposed  to be
issued in the notice  referred to above,  the Company shall have sixty (60) days
thereafter to sell (or enter into an agreement pursuant to which the sale of New
Securities  covered thereby shall be closed,  if at all, within thirty [30] days
from the date of such  agreement) with the New Securities  respecting  which the
Rights  Holders'  rights were not exercised at a price and upon general terms no
more favorable to the purchasers thereof than specified in the Company's notice.
In the event the Company has not sold the New Securities  within such sixty (60)
day period (or sold and issued New  Securities in accordance  with the foregoing
within thirty (30) days from the date of such agreement),  the Company shall not
thereafter  issue or sell any New  Securities  without  first  offering such New
Securities to the Rights Holders in the manner provided above.

            (E) The Right of First Refusal  granted under this  Agreement  shall
expire  immediately  after the closing of the Company's  initial Public Offering
pursuant to a  registration  statement  filed and declared  effective  under the
Securities  Act or upon  some  other  means by which the  shares of the  Company
become publicly traded and listed on a national securities exchange or listed on
the National Market System (the "NMS") of the National Association of Securities
Dealers  Automated  Quotation  System  ("NASDAQ"),  but shall be in effect  with
respect to such transaction.

            (F) This Right of First Refusal is nonassignable  except if (i) such
assignee agrees to be bound by the provisions of this Section 8 and (ii) written
notice of such transfer is promptly furnished to the Company.

            (G) This Right of First  Refusal  shall  terminate  as to any Rights
Holder who no longer owns any shares of capital stock  issuable upon  conversion
of the Warrants as of the date of the notice referred to above.
