         The following constitute the provisions of the 2000 Employee Stock
Purchase Plan of Triton Network Systems, Inc.

         1.       Purpose. The purpose of the Plan is to provide employees of
the Company and its Designated Subsidiaries with an opportunity to purchase
Common Stock of the Company through accumulated payroll deductions. It is the
intention of the Company to have the Plan qualify as an "Employee Stock Purchase
Plan" under Section 423 of the Internal Revenue Code of 1986, as amended. The
provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

         2.       Definitions.

                  (a)      "Board" shall mean the Board of Directors of the
Company or any committee thereof designated by the Board of Directors of the
Company in accordance with Section 14 of the Plan.

                  (b)      "Code" shall mean the Internal Revenue Code of 1986,

Employee of the Company for tax purposes whose customary employment with the
Company is at least twenty (20) hours per week and more than five (5) months in
any calendar year. For purposes of the Plan, the employment relationship shall
be treated as continuing intact while the individual is on sick leave or other
leave of absence approved by the Company. Where the period of leave exceeds 90
days and the individual's right to reemployment is not guaranteed either by
statute or by contract, the employment relationship shall be deemed to have
terminated on the 91st day of such leave.

                  (h)      "Enrollment Date" shall mean the first Trading Day of
each Offering Period.

established stock exchange or a national market system, including without
limitation the Nasdaq National Market or The Nasdaq SmallCap Market of The
Nasdaq Stock Market, its Fair Market Value shall be the closing sales price for
such stock (or the closing bid, if no sales were reported) as quoted on such
exchange or system on the date of determination, as reported in The Wall Street
Journal or such other source as the Board deems reliable;

                           (ii)  If the Common Stock is regularly quoted by a
recognized securities dealer but selling prices are not reported, its Fair
Market Value shall be the mean of the closing bid and asked prices for the
Common Stock on the date of determination, as reported in The Wall Street
Journal or such other source as the Board deems reliable;

                           (iii) In the absence of an established market for
the Common Stock, the Fair Market Value thereof shall be determined in good
faith by the Board; or

                           (iv)  For purposes of the Enrollment Date of the
first Offering Period under the Plan, the Fair Market Value shall be the initial

months later; provided, however, that the first Offering Period under the Plan
shall commence with the first Trading Day on or after the date on which the
Securities and Exchange Commission declares the Company's Registration Statement
effective and ending on the first Trading Day on or after May 1, 2001. The
duration and timing of Offering Periods may be changed pursuant to Section 4 of
this Plan.

                  (l)      "Plan" shall mean this 2000 Employee Stock Purchase
Plan.

                  (m)      "Purchase Period" shall mean the approximately six
month period commencing on one Exercise Date and ending with the next Exercise
Date, except that the first Purchase Period of any Offering Period shall
commence on the Enrollment Date and end with the next Exercise Date.

                  (n)      "Purchase Price" shall mean 85% of the Fair Market
Value of a share of Common Stock on the Enrollment Date or on the Exercise Date,

stock exchanges and the Nasdaq System are open for trading.

         3.       Eligibility.

                  (a)      Any Employee who shall be employed by the Company on
a given Enrollment Date shall be eligible to participate in the Plan.

                  (b)      Any provisions of the Plan to the contrary
notwithstanding, no Employee shall be granted an option under the Plan (i) to
the extent that, immediately after the grant, such Employee (or any other person
whose stock would be attributed to such Employee pursuant to Section 424(d) of
the Code) would own capital stock of the Company and/or hold outstanding options
to purchase such stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of the capital stock of the
Company or of any Subsidiary, or (ii) to the extent that his or her rights to
purchase stock under all employee stock purchase plans of the Company and its
subsidiaries accrues at a rate which exceeds Twenty-Five Thousand Dollars
($25,000) worth of stock (determined at the fair market value of the shares at
the time such option is granted) for each calendar year in which such option is
outstanding at any time.

         4.       Offering Periods. The Plan shall be implemented by
consecutive, overlapping Offering Periods with a new Offering Period commencing
on the first Trading Day on or after May 1 and November 1 each year, or on such
other date as the Board shall determine, and continuing thereafter until
terminated in accordance with Section 20 hereof; provided, however, that the
first Offering Period under the Plan shall commence with the first Trading Day
on or after the date on which the Securities and Exchange Commission declares
the Company's Registration Statement effective and ending on the first Trading
Day on or after May 1, 2001. The Board shall have the power to change the
duration of Offering Periods (including the commencement dates thereof) with
respect to future offerings without stockholder approval if such change is
announced at least five (5) days prior to the scheduled beginning of the first
Offering Period to be affected thereafter.

         5.       Participation.

                  (a)      An eligible Employee may become a participant in the
Plan by completing a subscription agreement authorizing payroll deductions in
the form of Exhibit A to this Plan and filing it with the Company's payroll
office prior to the applicable Enrollment Date.

                  (b)      Payroll deductions for a participant shall commence
on the first payroll following the Enrollment Date and shall end on the last
payroll in the Offering Period to which such authorization is applicable, unless
sooner terminated by the participant as provided in Section 10 hereof.

                                      -3-
<PAGE>   4

         6.       Payroll Deductions.

                  (a)      At the time a participant files his or her
subscription agreement, he or she shall elect to have payroll deductions made on
each pay day during the Offering Period in an amount not exceeding ten (10%) of
the Compensation which he or she receives on each pay day during the Offering
Period; provided, however, that should a pay day occur on an Exercise Date, a
participant shall have the payroll deductions made on such day applied to his or
her account under the new Offering Period or Purchase Period, as the case may
be.

                  (b)      All payroll deductions made for a participant shall
be credited to his or her account under the Plan and shall be withheld in whole
percentages only. A participant may not make any additional payments into such
account.

                  (c)      A participant may discontinue his or her
participation in the Plan as provided in Section 10 hereof, or may increase or
decrease the rate of his or her payroll deductions during the Offering Period by
completing or filing with the Company a new subscription agreement authorizing a
change in payroll deduction rate. The Company may, in its discretion, limit the
nature and/or number of participation rate changes during any Offering Period,
and may establish such other conditions or limitations as it deems appropriate
for Plan administration. The change in rate shall be effective with the first
full payroll period following five (5) business days after the Company's receipt
of the new subscription agreement unless the Company elects to process a given
change in participation more quickly. A participant's subscription agreement
shall remain in effect for successive Offering Periods unless terminated as
provided in Section 10 hereof.

                  (d)      Notwithstanding the foregoing, to the extent
necessary to comply with Section 423(b)(8) of the Code and Section 3(b) hereof,
a participant's payroll deductions may be decreased to zero percent (0%) at any
time during a Purchase Period. Payroll deductions shall recommence at the rate
provided in such participant's subscription agreement at the beginning of the
first Purchase Period which is scheduled to end in the following calendar year,
unless terminated by the participant as provided in Section 10 hereof.

                  (e)      At the time the option is exercised, in whole or in
part, or at the time some or all of the Company's Common Stock issued under the
Plan is disposed of, the participant must make adequate provision for the
Company's federal, state, or other tax withholding obligations, if any, which
arise upon the exercise of the option or the disposition of the Common Stock. At
any time, the Company may, but shall not be obligated to, withhold from the
participant's compensation the amount necessary for the Company to meet
applicable withholding obligations, including any withholding required to make
available to the Company any tax deductions or benefits attributable to sale or
early disposition of Common Stock by the Employee.

         7.       Grant of Option. On the Enrollment Date of each Offering
Period, each eligible Employee participating in such Offering Period shall be
granted an option to purchase on each Exercise Date during such Offering Period
(at the applicable Purchase Price) up to a number of shares of the Company's
Common Stock determined by dividing such Employee's payroll deductions
accumulated prior to such Exercise Date and retained in the Participant's
account as of the Exercise Date by the applicable Purchase Price; provided that
in no event shall an Employee be permitted to purchase during each Purchase
Period more than 1,250 shares of the Company's Common Stock

                                      -4-
<PAGE>   5

(subject to any adjustment pursuant to Section 19), and provided further that
such purchase shall be subject to the limitations set forth in Sections 3(b) and
12 hereof. The Board may, for future Offering Periods, increase or decrease, in
its absolute discretion, the maximum number of shares of the Company's Common
Stock an Employee may purchase during each Purchase Period of such Offering
Period. Exercise of the option shall occur as provided in Section 8 hereof,
unless the participant has withdrawn pursuant to Section 10 hereof. The option
shall expire on the last day of the Offering Period.

         8.       Exercise of Option.

                  (a)      Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

                  (b)      If the Board determines that, on a given Exercise
Date, the number of shares with respect to which options are to be exercised may
exceed (i) the number of shares of Common Stock that were available for sale
under the Plan on the Enrollment Date of the applicable Offering Period, or (ii)
the number of shares available for sale under the Plan on such Exercise Date,
the Board may in its sole discretion (x) provide that the Company shall make a
pro rata allocation of the shares of Common Stock available for purchase on such
Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall
be practicable and as it shall determine in its sole discretion to be equitable
among all participants exercising options to purchase Common Stock on such
Exercise Date, and continue all Offering Periods then in effect, or (y) provide
that the Company shall make a pro rata allocation of the shares available for
purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform
a manner as shall be practicable and as it shall determine in its sole
discretion to be equitable among all participants exercising options to purchase
Common Stock on such Exercise Date, and terminate any or all Offering Periods
then in effect pursuant to Section 20 hereof. The Company may make pro rata
allocation of the shares available on the Enrollment Date of any applicable
Offering Period pursuant to the preceding sentence, notwithstanding any
authorization of additional shares for issuance under the Plan by the Company's
stockholders subsequent to such Enrollment Date.

         9.       Delivery. As promptly as practicable after each Exercise Date
on which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

                                      -5-
<PAGE>   6

         10.      Withdrawal.

                  (a) A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any time by giving written notice to the
Company in the form of Exhibit B to this Plan. All of the participant's payroll
deductions credited to his or her account shall be paid to such participant
promptly after receipt of notice of withdrawal and such participant's option for
the Offering Period shall be automatically terminated, and no further payroll
deductions for the purchase of shares shall be made for such Offering Period. If
a participant withdraws from an Offering Period, payroll deductions shall not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

                  (b) A participant's withdrawal from an Offering Period shall
not have any effect upon his or her eligibility to participate in any similar
plan which may hereafter be adopted by the Company or in succeeding Offering
Periods which commence after the termination of the Offering Period from which
the participant withdraws.

         11.      Termination of Employment.

                  Upon a participant's ceasing to be an Employee, for any
reason, he or she shall be deemed to have elected to withdraw from the Plan and
the payroll deductions credited to such participant's account during the
Offering Period but not yet used to exercise the option shall be returned to
such participant or, in the case of his or her death, to the person or persons
entitled thereto under Section 15 hereof, and such participant's option shall be
automatically terminated. The preceding sentence notwithstanding, a participant
who receives payment in lieu of notice of termination of employment shall be
treated as continuing to be an Employee for the participant's customary number
of hours per week of employment during the period in which the participant is
subject to such payment in lieu of notice.

         12.      Interest. No interest shall accrue on the payroll deductions
of a participant in the Plan.

         13.      Stock.

                  (a)      Subject to adjustment upon changes in capitalization
of the Company as provided in Section 19 hereof, the maximum number of shares of
the Company's Common Stock which shall be made available for sale under the Plan
shall be five hundred thousand (500,000) shares.

                  (b)      The participant shall have no interest or voting
right in shares covered by his option until such option has been exercised.

                  (c)      Shares to be delivered to a participant under the
Plan shall be registered in the name of the participant or in the name of the
participant and his or her spouse.

                                      -6-
<PAGE>   7

         14.      Administration. The Plan shall be administered by the Board or
a committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

         15.      Designation of Beneficiary.

                  (a)      A participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
participant's account under the Plan in the event of such participant's death
subsequent to an Exercise Date on which the option is exercised but prior to
delivery to such participant of such shares and cash. In addition, a participant
may file a written designation of a beneficiary who is to receive any cash from
the participant's account under the Plan in the event of such participant's
death prior to exercise of the option. If a participant is married and the
designated beneficiary is not the spouse, spousal consent shall be required for
such designation to be effective.

                  (b)      Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

         16.      Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

         17.      Use of Funds. All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions.

         18.      Reports. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

                                      -7-

         19.      Adjustments Upon Changes in Capitalization, Dissolution,
Liquidation, Merger or Asset Sale.

                  (a)      Changes in Capitalization. Subject to any required
action by the stockholders of the Company, the Reserves, the maximum number of
shares each participant may purchase each Purchase Period (pursuant to Section
7), as well as the price per share and the number of shares of Common Stock
covered by each option under the Plan which has not yet been exercised shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of shares of Common Stock effected without
receipt of consideration by the Company; provided, however, that conversion of
any convertible securities of the Company shall not be deemed to have been
"effected without receipt of consideration." Such adjustment shall be made by
the Board, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an option.

                  (b)      Dissolution or Liquidation. In the event of the
proposed dissolution or liquidation of the Company, the Offering Period then in
progress shall be shortened by setting a new Exercise Date (the "New Exercise
Date"), and shall terminate immediately prior to the consummation of such
proposed dissolution or liquidation, unless provided otherwise by the Board. The
New Exercise Date shall be before the date of the Company's proposed dissolution
or liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

                  (c)      Merger or Asset Sale. In the event of a proposed sale
of all or substantially all of the assets of the Company, or the merger of the
Company with or into another corporation, each outstanding option shall be
assumed or an equivalent option substituted by the successor corporation or a
Parent or Subsidiary of the successor corporation. In the event that the
successor corporation refuses to assume or substitute for the option, any
Purchase Periods then in progress shall be shortened by setting a new Exercise
Date (the "New Exercise Date") and any Offering Periods then in progress shall
end on the New Exercise Date. The New Exercise Date shall be before the date of
the Company's proposed sale or merger. The Board shall notify each participant
in writing, at least ten (10) business days prior to the New Exercise Date, that
the Exercise Date for the participant's option has been changed to the New
Exercise Date and that the participant's option shall be exercised automatically
on the New Exercise Date, unless prior to such date the participant has
withdrawn from the Offering Period as provided in Section 10 hereof.

         20.      Amendment or Termination.

                  (a)      The Board of Directors of the Company may at any time
and for any reason terminate or amend the Plan. Except as provided in Section 19
hereof, no such termination can

                                      -8-
<PAGE>   9
affect options previously granted, provided that an Offering Period may be
terminated by the Board of Directors on any Exercise Date if the Board
determines that the termination of the Offering Period or the Plan is in the
best interests of the Company and its stockholders. Except as provided in
Section 19 and this Section 20 hereof, no amendment may make any change in any
option theretofore granted which adversely affects the rights of any
participant. To the extent necessary to comply with Section 423 of the Code (or
any successor rule or provision or any other applicable law, regulation or
stock exchange rule), the Company shall obtain stockholder approval in such a
manner and to such a degree as required.

         (b)      Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods,
limit the frequency and/or number of changes in the amount withheld during an
Offering Period, establish the exchange ratio applicable to amounts withheld in
a currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

         (c)      In the event the Board determines that the ongoing operation
of the Plan may result in unfavorable financial accounting consequences, the
Board may, in its discretion and, to the extent necessary or desirable, modify
or amend the Plan to reduce or eliminate such accounting consequence including,
but not limited to:

                  (i)      altering the Purchase Price for any Offering Period
including an Offering Period underway at the time of the change in Purchase
Price;

                  (ii)     shortening any Offering Period so that Offering
Period ends on a new Exercise Date, including an Offering Period underway at
the time of the Board action; and

                  (iii)    allocating shares.

         Such modifications or amendments shall not require stockholder
approval or the consent of any Plan participants.

         21.      Notices. All notices or other communications by a participant
to the Company under or in connection with the Plan shall be deemed to have
been duly given when received in the form specified by the Company at the
location, or by the person, designated by the Company for the receipt thereof.

         22.      Conditions Upon Issuance of Shares. Shares shall not be
issued with respect to an option unless the exercise of such option and the
issuance and delivery of such shares pursuant thereto shall comply with all

                             SUBSCRIPTION AGREEMENT

_____ Original Application                          Enrollment Date:___________
_____ Change in Payroll Deduction Rate

_____ Change of Beneficiary(ies)

1.       ____________________ hereby elects to participate in the Triton
         Network Systems, Inc. Employee Stock Purchase Plan (the "Employee
         Stock Purchase Plan") and subscribes to purchase shares of the
         Company's Common Stock in accordance with this Subscription Agreement
         and the Employee Stock Purchase Plan.

2.       I hereby authorize payroll deductions from each paycheck in the amount
         of ____% of my Compensation on each payday (from 0 to _____%) during
         the Offering Period in accordance with the Employee Stock Purchase
         Plan. (Please note that no fractional percentages are permitted.)

3.       I understand that said payroll deductions shall be accumulated for the
         purchase of shares of Common Stock at the applicable Purchase Price
         determined in accordance with the Employee Stock Purchase Plan. I
         understand that if I do not withdraw from an Offering Period, any
         accumulated payroll deductions will be used to automatically exercise
         my option.

4.       I have received a copy of the complete Employee Stock Purchase Plan. I
         understand that my participation in the Employee Stock Purchase Plan
         is in all respects subject to the terms of the Plan. I understand that
         my ability to exercise the option under this Subscription Agreement is
         subject to stockholder approval of the Employee Stock Purchase Plan.

5.       Shares purchased for me under the Employee Stock Purchase Plan should
         be issued in the name(s) of (Employee or Employee and Spouse only).

6.       I understand that if I dispose of any shares received by me pursuant
         to the Plan within 2 years after the Enrollment Date (the first day of
         the Offering Period during which I purchased such shares) or one year
         after the Exercise Date, I will be treated for federal income tax
         purposes as having received ordinary income at the time of such
         disposition in an amount equal to the excess of the fair market value
         of the shares at the time such shares were purchased by me over the
         price which I paid for the shares. I hereby agree to notify the
         Company in writing within 30 days after the date of any disposition of
         my shares and I will make adequate provision for Federal, state or
         other tax withholding obligations, if any, which arise upon the

<PAGE>   12

         disposition of the Common Stock. The Company may, but will not be
         obligated to, withhold from my compensation the amount necessary to
         meet any applicable withholding obligation including any withholding
         necessary to make available to the Company any tax deductions or
         benefits attributable to sale or early disposition of Common Stock by
         me. If I dispose of such shares at any time after the expiration of
         the 2-year and 1-year holding periods, I understand that I will be
         treated for federal income tax purposes as having received income only
         at the time of such disposition, and that such income will be taxed as
         ordinary income only to the extent of an amount equal to the lesser of
         (1) the excess of the fair market value of the shares at the time of
         such disposition over the purchase price which I paid for the shares,
         or (2) 15% of the fair market value of the shares on the first day of
         the Offering Period. The remainder of the gain, if any, recognized on
         such disposition will be taxed as capital gain.

7.       I hereby agree to be bound by the terms of the Employee Stock Purchase
         Plan. The effectiveness of this Subscription Agreement is dependent
         upon my eligibility to participate in the Employee Stock Purchase
         Plan.

8.       In the event of my death, I hereby designate the following as my
         beneficiary(ies) to receive all payments and shares due me under the
         Employee Stock Purchase Plan:

                                    full of forty-nine (49) consecutive months
                                    from the thirtieth day of the month
                                    coincident with or (as the case may be) the

Adjustment to Monthly Payments:     If, on the second business day preceding the
                                    Closing Date for each Loan the highest yield
                                    for the four-year U. S. Treasury Notes as
                                    published in The Wall Street Journal on such
                                    date is greater or less than the yield as
                                    published on November 15, 1999, the Monthly
                                    Payments shall be increased or decreased
                                    (point for point) to reflect such change in
                                    the yield. The yield as of November 15, 1999
                                    was 6.01%. As of the Closing Date, the
                                    Monthly Payments with respect to the

                                    shall be then due the Lender. The
                                    Application Fee of $25,000 previously paid,
                                    by the Borrower shall be applied to the

                                    master loan and security agreement (or
                                    schedules) and those of this Commitment
                                    Letter, the master loan and security
                                    Agreement (or schedules) shall control.

                                    yield for three-year U.S. Treasury Notes as
                                    published in The Wall Street Journal on such

                                    31st day of a month. If the Closing Date is
                                    the 31st day of a month, Interim Rent shall
                                    accrue until the 29th day of the next
                                    following month. If the Closing Date is the
                                    30th day of a month, there shall be no
                                    Interim Rent. Interim Rent shall be at the

                                    would be the price of the most current
                                    equity offering. The warrants shall be
                                    exercisable from their date of grant until
                                    the close of business seven years from the
                                    date of grant. The warrants shall contain
                                    (a) piggyback registration rights, subject
                                    to customary underwriter cutbacks or

                                    advance notice and opportunity to exercise

                                    provisions, and (e) a one time right at any
                                    time subsequent to an IPO in conjunction
                                    with other holders of registration rights
                                    granted by you to cause a registration for
