THIS WARRANT AND THE SHARES ISSUABLE UPON THE EXERCISE OF THIS WARRANT HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. EXCEPT AS
OTHERWISE SET FORTH HEREIN, NEITHER THIS WARRANT NOR ANY OF SUCH SHARES MAY BE
SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
STATEMENT FOR SUCH SECURITIES UNDER SAID ACT, OR AN OPINION OF COUNSEL, IN FORM,
SUBSTANCE AND SCOPE REASONABLY SATISFACTORY TO THE COMPANY, THAT REGISTRATION IS
NOT REQUIRED UNDER SUCH ACT OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT.

                                                RIGHT TO PURCHASE
                                                -------------------------------
                                                4,285,714 shares of Common
                                                Stock, par value $.000125 per
                                                share

                             STOCK PURCHASE WARRANT

THIS CERTIFIES THAT, for value received, Invest Inc. ("Invest"), or its
registered assigns, is entitled to purchase from Breakaway Solutions, Inc., a
Delaware corporation (the "Company"), at any time or from time to time during
the period specified in Paragraph 2 hereof, Four Million Two Hundred Eighty Five
Thousand Seven Hundred Fourteen (4,285,714) fully paid and nonassessable shares
of the Company's Common Stock, par value $.000125 per share (the "Common Stock")
subject to adjustment as provided in Section 1 below. The exercise price for the
shares of Common Stock issuable hereunder (the "Exercise Price) shall be the
lesser of: (i) $0.70 and (ii) the average Closing Bid Price of the Company's
Common Stock for the five (5) Trading Days immediately prior to January 31,
2002.

     The term "Warrant Shares," as used herein, refers to the shares of Common
Stock purchasable hereunder. The Warrant Shares and the Exercise Price are
subject to adjustment as provided in Paragraph 5 hereof. The term "Warrant" or
"Warrants" means this Warrant. The term "Securities Purchase Agreement," as used
herein, refers to that certain Securities Purchase Agreement, dated December 11,
2000, by and among the Company, regardless of any subsequent rescission or
modification thereof.

     This Warrant is subject to the following terms, provisions, and conditions:

     1. ADJUSTMENT TO NUMBER OF SHARES ISSUABLE. In the event the Exercise Price
is less than the purchase price for the Purchased Shares (as such purchase price
has been modified by that certain Settlement Agreement and Mutual Release of
Claims, date as of February 6, 2001)

<PAGE>

(the "Settlement Agreement"), the number of shares of Common Stock issuable
upon exercise of this Warrant shall be adjusted upward by an amount equal to the
percentage of adjustment made to the Exercise Price. By way of illustration, if
the purchase price for the Purchased Shares was $0.70 per share on the date of
the Settlement Agreement, and the average Closing Bid Price of the Company's
Common Stock for the five (5) Trading Days immediately prior to January 31, 2002
was $0.50 per share, the number of shares of Common Stock issuable hereunder
would be increased by a factor of 28.57%, for an aggregate adjusted amount of
5,142,800 shares of Common Stock issuable under this Warrant.

     2. MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.

     a) Subject to the provisions hereof, this Warrant may be exercised by the
holder hereof, in whole or in part, by the surrender of this Warrant, together
with a completed exercise agreement in the form attached hereto (the "Exercise
Agreement"), to the Company during normal business hours on any business day at
the Company's principal executive offices (or such other office or agency of the
Company as it may designate by notice to the holder hereof), and upon (i)
payment to the Company in cash, by certified or official bank check or by wire
transfer for the account of the Company of the Exercise Price for the Warrant
Shares specified in the Exercise Agreement or (ii) if the resale of the Warrant
Shares by the holder is not then registered pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"Securities Act"), delivery to the Company of a written notice of an election to
effect a "Cashless Exercise" (as defined in Section 2(b) below) for the Warrant
Shares specified in the Exercise Agreement. The Warrant Shares so purchased
shall be deemed to be issued to the holder hereof or such holder's designee, as
the record owner of such shares, as of the close of business on the date on
which this Warrant shall have been surrendered, the completed Exercise Agreement
shall have been delivered, and payment shall have been made for such shares (or
an election to effect a Cashless Exercise has been made) as set forth above.
Certificates for the Warrant Shares so purchased, representing the aggregate
number of shares specified in the Exercise Agreement, shall be delivered to the
holder hereof within a reasonable time, not exceeding three (3) Trading Days,
after this Warrant shall have been so exercised. The certificates so delivered
shall be in such denominations as may be requested by the holder hereof and
shall be registered in the name of such holder or such other name as shall be
designated by such holder. If this Warrant shall have been exercised only in
part, then, unless this Warrant has expired, the Company shall, at its expense,
at the time of delivery of such certificates, deliver to the holder a new
Warrant representing the number of shares with respect to which this Warrant
shall not then have been exercised.

     b) CASHLESS EXERCISE. Notwithstanding anything to the contrary contained in
this Warrant, if the resale of the Warrant Shares by the holder is not then
registered pursuant to an effective registration statement under the Securities
Act, this Warrant may be exercised by presentation and surrender of this Warrant
to the Company at its principal executive offices with a written notice of the
holder's intention to effect a cashless exercise, including a calculation of the
number of shares of Common Stock to be issued upon such exercise in accordance
with the terms hereof (a "Cashless Exercise"). In the event of a Cashless
Exercise, in lieu of paying the Exercise Price in cash, the holder shall
surrender this Warrant for that number of shares of

                                      -2-
<PAGE>

Common Stock determined by multiplying the number of Warrant Shares to which it
would otherwise be entitled by a fraction, the numerator of which shall be the
difference between the then current Market Price per share of the Common Stock
and the Exercise Price, and the denominator of which shall be the then current
Market Price per share of Common Stock.

     3. PERIOD OF EXERCISE. This Warrant is exercisable at any time or from time
to time on or after the date on which this Warrant is issued and delivered
pursuant to the terms of the Securities Purchase Agreement (the "Issue Date"),
subject to the increase in the Company's authorized shares of Common Stock
provided in Section 4(b) below and before 5:00 p.m., New York City time, on the
fourth (4th) anniversary of the Issue Date (the "Exercise Period").

     4. CERTAIN AGREEMENTS OF THE COMPANY. The Company hereby covenants and
agrees as follows:

          (a) SHARES TO BE FULLY PAID. All Warrant Shares will, upon issuance in
     accordance with the terms of this Warrant, be validly issued, fully paid,
     and nonassessable and free from all taxes, liens, and charges with respect
     to the issue thereof.

          (b) RESERVATION OF SHARES. The Company shall use its best efforts, as
     soon as practicable, to increase the number of shares of Common Stock
     authorized for issuance under its Third Amended and Restated Certificate of
     Incorporation to allow the Company to reserve a sufficient number of such
     shares of Common Stock to provide for the exercise of this Warrant, and the
     Company shall thereafter reserve an appropriate number of shares at all
     times to fulfill its obligations hereunder.

          (c) LISTING. The Company shall promptly secure the listing of the
     shares of Common Stock issuable upon exercise of this Warrant upon each
     national securities exchange or automated quotation system, if any, upon
     which shares of Common Stock are then listed (subject to official notice of
     issuance upon exercise of this Warrant) and shall maintain, so long as any
     other shares of Common Stock shall be so listed, such listing of all shares
     of Common Stock from time to time issuable upon the exercise of this
     Warrant; and the Company shall so list on each national securities exchange
     or automated quotation system, as the case may be, and shall maintain such
     listing of, any other shares of capital stock of the Company issuable upon
     the exercise of this Warrant if and so long as any shares of the same class
     shall be listed on such national securities exchange or automated quotation
     system.

          (d) CERTAIN ACTIONS PROHIBITED. The Company will not, by amendment of
     its charter or through any reorganization, transfer of assets,
     consolidation, merger, dissolution, issue or sale of securities, or any
     other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms to be observed or performed by it
     hereunder, but will at all times in good faith assist in the carrying out
     of all the provisions of this Warrant and in the taking of all such action
     as may reasonably be requested by the holder of this Warrant in order to
     protect the exercise privilege of the holder of this Warrant against
     dilution or other impairment, consistent with the tenor and purpose of this
     Warrant. Without limiting the generality of the foregoing, the

                                      -3-
<PAGE>

     Company (i) will not increase the par value of any shares of Common Stock
     receivable upon the exercise of this Warrant above the Exercise Price then
     in effect, and (ii) will take all such actions as may be necessary or
     appropriate in order that the Company may validly and legally issue fully
     paid and nonassessable shares of Common Stock upon the exercise of this
     Warrant.

          (e) SUCCESSORS AND ASSIGNS. This Warrant will be binding upon any
     entity succeeding to the Company by merger, consolidation, or acquisition
     of all or substantially all the Company's assets.

     5. ANTIDILUTION PROVISIONS. During the Exercise Period, the Exercise Price
and the number of Warrant Shares shall be subject to adjustment from time to
time as provided in this Paragraph 5.

     In the event that any adjustment of the Exercise Price as required herein
results in a fraction of a cent, such Exercise Price shall be rounded up to the
nearest cent.

          (a) ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES UPON ISSUANCE OF
     COMMON STOCK. Except as otherwise provided in Paragraphs 5(c) and) 5(e)
     hereof, if and whenever on or after the Issue Date of this Warrant, the
     Company issues or sells, or in accordance with Paragraph 5(b) hereof is
     deemed to have issued or sold, any shares of Common Stock for no
     consideration or for a consideration per share (before deduction of
     reasonable expenses or commissions or underwriting discounts or allowances
     in connection therewith) less than the Market Price (as hereinafter
     defined) on the date of issuance (or deemed issuance) of such Common Stock
     (a "Dilutive Issuance"), then immediately upon the Dilutive Issuance, the
     Exercise Price will be reduced to a price determined by multiplying the
     Exercise Price in effect immediately prior to the Dilutive Issuance by a
     fraction, (i) the numerator of which is an amount equal to the sum of (x)
     the number of shares of Common Stock actually outstanding immediately prior
     to the Dilutive Issuance, plus (y) the quotient of the aggregate
     consideration, calculated as set forth in Paragraph 5(b) hereof, received
     by the Company upon such Dilutive Issuance divided by the Market Price in
     effect immediately prior to the Dilutive Issuance, and (ii) the denominator
     of which is the total number of shares of Common Stock Deemed Outstanding
     (as defined below) immediately after the Dilutive Issuance.

          (b) EFFECT ON EXERCISE PRICE OF CERTAIN EVENTS. For purposes of
     determining the adjusted Exercise Price under Paragraph 5(a) hereof, the
     following will be applicable:

               (i) ISSUANCE OF RIGHTS OR OPTIONS. If the Company in any manner
          issues or grants any warrants, rights or options, whether or not
          immediately exercisable, to subscribe for or to purchase Common Stock
          or other securities convertible into or exchangeable for Common Stock
          ("Convertible Securities") (such warrants, rights and options to
          purchase Common Stock or Convertible Securities are hereinafter
          referred to as "Options") and the price per share for which Common
          Stock is issuable upon the exercise of such Options is less than the
          Market Price on the date of issuance or grant of such Options, then
          the maximum total number of shares of Common Stock issuable upon the
          exercise of all such Options will, as of the date of the issuance or
          grant of such Options, be deemed to be outstanding and to have been
          issued and sold by the Company

                                      -4-
<PAGE>

          for such price per share. For purposes of the preceding sentence, the
          "price per share for which Common Stock is issuable upon the exercise
          of such Options" is determined by dividing (i) the total amount, if
          any, received or receivable by the Company as consideration for the
          issuance or granting of all such Options, plus the minimum aggregate
          amount of additional consideration, if any, payable to the Company
          upon the exercise of all such Options, plus, in the case of
          Convertible Securities issuable upon the exercise of such Options, the
          minimum aggregate amount of additional consideration payable upon the
          conversion or exchange thereof at the time such Convertible Securities
          first become convertible or exchangeable, by (ii) the maximum total
          number of shares of Common Stock issuable upon the exercise of all
          such Options (assuming full conversion of Convertible Securities, if
          applicable). No further adjustment to the Exercise Price will be made
          upon the actual issuance of such Common Stock upon the exercise of
          such Options or upon the conversion or exchange of Convertible
          Securities issuable upon exercise of such Options.

               (ii) ISSUANCE OF CONVERTIBLE SECURITIES. If the Company in any
          manner issues or sells any Convertible Securities, whether or not
          immediately convertible (other than where the same are issuable upon
          the exercise of Options) and the price per share for which Common
          Stock is issuable upon such conversion or exchange is less than the
          Market Price on the date of issuance of such Convertible Securities,
          then the maximum total number of shares of Common Stock issuable upon
          the conversion or exchange of all such Convertible Securities will, as
          of the date of the issuance of such Convertible Securities, be deemed
          to be outstanding and to have been issued and sold by the Company for
          such price per share. For the purposes of the preceding sentence, the
          "price per share for which Common Stock is issuable upon such
          conversion or exchange" is determined by dividing (i) the total
          amount, if any, received or receivable by the Company as consideration
          for the issuance or sale of all such Convertible Securities, plus the
          minimum aggregate amount of additional consideration, if any, payable
          to the Company upon the conversion or exchange thereof at the time
          such Convertible Securities first become convertible or exchangeable,
          by (ii) the maximum total number of shares of Common Stock issuable
          upon the conversion or exchange of all such Convertible Securities. No
          further adjustment to the Exercise Price will be made upon the actual
          issuance of such Common Stock upon conversion or exchange of such
          Convertible Securities.

               (iii) CHANGE IN OPTION PRICE OR CONVERSION RATE. If there is a
          change at any time in (i) the amount of additional consideration
          payable to the Company upon the exercise of any Options; (ii) the
          amount of additional consideration, if any, payable to the Company
          upon the conversion or exchange of any Convertible Securities; or
          (iii) the rate at which any Convertible Securities are convertible
          into or exchangeable for Common Stock, the Exercise Price in effect at
          the time of such change will be readjusted to the Exercise Price which
          would have been in effect at such time had such Options or Convertible
          Securities still outstanding provided for such changed additional
          consideration or changed conversion rate, as the case may be, at the
          time initially granted, issued or sold.

                                      -5-
<PAGE>

               (iv) TREATMENT OF EXPIRED OPTIONS AND UNEXERCISED CONVERTIBLE
          SECURITIES. If, in any case, the total number of shares of Common
          Stock issuable upon exercise of any Option or upon conversion or
          exchange of any Convertible Securities is not, in fact, issued and the
          rights to exercise such Option or to convert or exchange such
          Convertible Securities shall have expired or terminated, the Exercise
          Price then in effect will be readjusted to the Exercise Price which
          would have been in effect at the time of such expiration or
          termination had such Option or Convertible Securities, to the extent
          outstanding immediately prior to such expiration or termination (other
          than in respect of the actual number of shares of Common Stock issued
          upon exercise or conversion thereof), never been issued.

               (v) CALCULATION OF CONSIDERATION RECEIVED. If any Common Stock,
          Options or Convertible Securities are issued, granted or sold for
          cash, the consideration received therefor for purposes of this Warrant
          will be the amount received by the Company therefor, before deduction
          of reasonable commissions, underwriting discounts or allowances or
          other reasonable expenses paid or incurred by the Company in
          connection with such issuance, grant or sale. In case any Common
          Stock, Options or Convertible Securities are issued or sold for a
          consideration part or all of which shall be other than cash, the
          amount of the consideration other than cash received by the Company
          will be the fair value of such consideration, except where such
          consideration consists of securities, in which case the amount of
          consideration received by the Company will be the Market Price thereof
          as of the date of receipt. In case any Common Stock, Options or
          Convertible Securities are issued in connection with any acquisition,
          merger or consolidation in which the Company is the surviving
          corporation, the amount of consideration therefor will be deemed to be
          the fair value of such portion of the net assets and business of the
          non-surviving corporation as is attributable to such Common Stock,
          Options or Convertible Securities, as the case may be. The fair value
          of any consideration other than cash or securities will be determined
          in good faith by the Board of Directors of the Company.

               (vi) EXCEPTIONS TO ADJUSTMENT OF EXERCISE PRICE. No adjustment to
          the Exercise Price will be made (i) upon the exercise of any warrants,
          options or convertible securities granted, issued and outstanding on
          the date of issuance of this Warrant and accurately reflected in the
          Company's last filing with the SEC and on the Company's most recent
          financial statements; (ii) upon the grant or exercise of any stock or
          options which may hereafter be granted or exercised under any employee
          benefit plan of the Company now existing or to be adopted in the
          future, provided that the issuance of such stock or options (x) is
          approved by a majority of the independent members of the Board of
          Directors of the Company or a majority of the members of a committee
          of independent directors established for such purpose and (y) if such
          grant or issuance is pursuant to an employee benefit plan to be
          adopted in the future, such plan is adopted in accordance with Rule
          16-3 under the Securities Exchange Act of 1934, as amended; and (z)
          does not exceed 20,000,000 shares in the aggregate;(iii) upon the
          exercise of the Warrants; or (iv) upon the issuance of Common Stock
          pursuant to the Securities Purchase Agreement (including additional
          shares of Common Stock issuable thereunder at the option of the holder
          of this Warrant) and the Settlement Agreement (including additional
          shares of Common Stock issuable thereunder at the option of the holder
          of any further warrant issued pursuant to such Settlement Agreement).

                                      -6-
<PAGE>

          (c) SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Company at any
     time on or after the Issue Date of this Warrant subdivides (by any stock
     split, stock dividend, recapitalization, reorganization, reclassification
     or otherwise) the shares of Common Stock acquirable hereunder into a
     greater number of shares, then, after the date of record for effecting such
     subdivision, the Exercise Price in effect immediately prior to such
     subdivision will be proportionately reduced. If the Company at any time on
     or after the Issue Date of this Warrant combines (by reverse stock split,
     recapitalization, reorganization, reclassification or otherwise) the shares
     of Common Stock acquirable hereunder into a smaller number of shares, then,
     after the date of record for effecting such combination, the Exercise Price
     in effect immediately prior to such combination will be proportionately
     increased.

          (d) ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of the
     Exercise Price pursuant to the provisions of this Paragraph 5, the number
     of shares of Common Stock issuable upon exercise of this Warrant shall be
     adjusted by multiplying a number equal to the Exercise Price in effect
     immediately prior to such adjustment by the number of shares of Common
     Stock issuable upon exercise of this Warrant immediately prior to such
     adjustment and dividing the product so obtained by the adjusted Exercise
     Price.

          (e) CONSOLIDATION, MERGER OR SALE. In case of any consolidation of the
     Company with, or merger of the Company into, any other corporation, or in
     case of any sale or conveyance of all or substantially all of the assets of
     the Company other than in connection with a plan of complete liquidation of
     the Company, then as a condition of such consolidation, merger or sale or
     conveyance, adequate provision will be made whereby the holder of this
     Warrant will have the right to acquire and receive upon exercise of this
     Warrant in lieu of the shares of Common Stock immediately theretofore
     acquirable upon the exercise of this Warrant, such shares of stock,
     securities or assets as may be issued or payable with respect to or in
     exchange for the number of shares of Common Stock immediately theretofore
     acquirable and receivable upon exercise of this Warrant had such
     consolidation, merger or sale or conveyance not taken place. In any such
     case, the Company will make appropriate provision to insure that the
     provisions of this Paragraph 5 hereof will thereafter be applicable as
     nearly as may be in relation to any shares of stock or securities
     thereafter deliverable upon the exercise of this Warrant. The Company will
     not effect any consolidation, merger or sale or conveyance unless, prior to
     the consummation thereof, the successor or acquiring entity (if other than
     the Company) and, if an entity different from the successor or acquiring
     entity, the entity whose capital stock or assets the holders of the Common
     Stock of the Company are entitled to receive as a result of such
     consolidation, merger or sale or conveyance assumes by written instrument
     the obligations under this Warrant (including under this Paragraph 5(e))
     and the obligations to deliver to the holder of this Warrant such shares of
     stock, securities or assets as, in accordance with the foregoing
     provisions, the holder may be entitled to acquire.

          (f) DISTRIBUTION OF ASSETS. In case the Company shall declare or make
     any distribution of its assets (including cash) to holders of Common Stock
     as a partial liquidating dividend, by way of return of capital or
     otherwise, then, after the date of record for determining stockholders
     entitled to such distribution, but prior to the date of distribution, the
     holder of this Warrant shall be entitled upon exercise of this Warrant for
     the purchase of any or all of the shares

                                      -7-
<PAGE>

     of Common Stock subject hereto, to receive the amount of such assets which
     would have been payable to the holder had such holder been the holder of
     such shares of Common Stock on the record date for the determination of
     stockholders entitled to such distribution.

          (g) NOTICE OF ADJUSTMENT. Upon the occurrence of any event which
     requires any adjustment of the Exercise Price, then, and in each such case,
     the Company shall give notice thereof to the holder of this Warrant, which
     notice shall state the Exercise Price resulting from such adjustment and
     the increase or decrease in the number of Warrant Shares purchasable at
     such price upon exercise, setting forth in reasonable detail the method of
     calculation and the facts upon which such calculation is based. Such
     calculation shall be certified by the chief financial officer of the
     Company.

          (h) MINIMUM ADJUSTMENT OF EXERCISE PRICE. No adjustment of the
     Exercise Price shall be made in an amount of less than 1% of the Exercise
     Price in effect at the time such adjustment is otherwise required to be
     made, but any such lesser adjustment shall be carried forward and shall be
     made at the time and together with the next subsequent adjustment which,
     together with any adjustments so carried forward, shall amount to not less
     than 1% of such Exercise Price.

          (i) NO FRACTIONAL SHARES. No fractional shares of Common Stock are to
     be issued upon the exercise of this Warrant, but the Company shall pay a
     cash adjustment in respect of any fractional share which would otherwise be
     issuable in an amount equal to the same fraction of the Market Price of a
     share of Common Stock on the date of such exercise.

          (j) OTHER NOTICES. In case at any time:

               (i) the Company shall declare any dividend upon the Common Stock
          payable in shares of stock of any class or make any other distribution

          earnings) to the holders of the Common Stock;

               (ii) the Company shall offer for subscription pro rata to the
          holders of the Common Stock any additional shares of stock of any
          class or other rights;

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

     then, in each such case, the Company shall give to the holder of this
     Warrant (a) notice of the date on which the books of the Company shall
     close or a record shall be taken for determining the holders of Common
     Stock entitled to receive any such dividend, distribution, or subscription

     and (b) in the case of any such reorganization, reclassification,
     consolidation, merger, sale, dissolution, liquidation or winding-up, notice
     of the date (or, if not then known, a reasonable approximation thereof by

     shall be given at least 30 days prior to the record date or the date on
     which the Company's books are closed in respect thereto. Failure to give
     any such notice or any defect therein shall not affect the validity of the
     proceedings referred to in clauses (i), (ii), (iii) and (iv) above.

          (k) CERTAIN EVENTS. If any event occurs of the type contemplated by
     the adjustment provisions of this Paragraph 5 but not expressly provided
     for by such provisions, the Company will give written notice of such event
     to the holder of this Warrant, which notice shall state the Exercise Price
     resulting from such adjustment and the increase or decrease in the number
     of Warrant Shares purchasable at such price upon exercise, setting forth in
     reasonable detail the method of calculation and the facts upon which such
     calculation is based, including a certification thereof by the chief
     financial officer of the Company, and the Company's Board of Directors will
     make an appropriate adjustment in the Exercise Price and the number of
     shares of Common Stock acquirable upon exercise of this Warrant so that the
     rights of the holder of this Warrant shall be neither enhanced nor
     diminished by such event.

          (l) CERTAIN DEFINITIONS.

               (i) "COMMON STOCK DEEMED OUTSTANDING" shall mean the number of
          shares of Common Stock actually outstanding (not including shares of
          Common Stock held in the treasury of the Company), plus (x) pursuant
          to Paragraph 5(b)(i) hereof, the maximum total number of shares of
          Common Stock issuable upon the exercise of Options, as of the date of

          reporting service mutually acceptable to and hereafter designated by
          the holder of this Warrant and the Company ("Bloomberg"), or (ii) if
          the Nasdaq is not the principal trading market for the shares of
          Common Stock, the average of the last reported sale prices on the
          principal trading market for the Common Stock during the same period
          as reported by Bloomberg, or (iii) if market value cannot be
          calculated as of such date on any of the foregoing bases, the Market
          Price shall be the fair market value as reasonably determined in good
          faith by (a) the Board of Directors of the Company or (b) at the
          option of a majority-in-interest of the holders of the outstanding

          valuation of businesses similar to the business of the Company. The
          manner of determining the Market Price of the Common Stock set forth
          in the foregoing definition shall apply with respect to any other
          security in respect of which a determination as to market value must
          be made hereunder.

               (iii) "COMMON STOCK," for purposes of this Paragraph 5, includes
          the Common Stock, par value $.000125 per share, and any additional
          class of stock of the Company having no preference as to dividends or
          distributions on liquidation, provided that the shares purchasable
          pursuant to this Warrant shall include only shares of Common Stock,
          par value $.000125 per share, in respect of which this Warrant is
          exercisable, or shares resulting from any subdivision or combination
          of such Common Stock, or in the case of any reorganization,
          reclassification, consolidation, merger, or sale of the character
          referred to in Paragraph 5(e) hereof, the stock or other securities or
          property provided for in such Paragraph.

               (iv) "CLOSING BID PRICE" means, for any security as of any date,
          the closing bid price on Nasdaq as reported by Bloomberg or, if Nasdaq
          is not the principal trading market for such security, the closing bid
          price of such security on the principal securities exchange or trading
          market where such security is listed or traded as reported by
          Bloomberg, or, if no closing bid price of such security is available
          in any of the foregoing manners, the average of the bid prices of any
          market makers for such security that are listed in the "pink sheets"
          by the National Quotation Bureau, Inc. If the Closing Bid Price cannot
          be calculated for such security on such date in the manner provided
          above, the Closing Bid Price shall be the fair market value as
          mutually determined by the Company and the holder of this Warrant.

               (v) "TRADING DAY" means any day on which the Common Stock is
          traded for any period on Nasdaq, or on the principal securities
          exchange or other securities market on which the Common Stock is then
          being traded.

Warrant or such shares for any issuance tax or other costs in respect thereof,

payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than the holder of this Warrant.

     7. NO RIGHTS OR LIABILITIES AS A SHAREHOLDER. This Warrant shall not
entitle the holder hereof to any voting rights or other rights as a shareholder

Agreement and/or Registration Rights Agreement (as defined below). No provision
of this Warrant, in the absence of affirmative action by the holder hereof to

privileges of the holder hereof, shall give rise to any liability of such holder
for the Exercise Price or as a shareholder of the Company, whether such
liability is asserted by the Company or by creditors of the Company.

     8. TRANSFER, EXCHANGE, AND REPLACEMENT OF WARRANT.

          (a) RESTRICTION ON TRANSFER. This Warrant and the rights granted to
     the holder hereof are transferable, in whole or in part, upon surrender of
     this Warrant, together with a properly executed assignment in the form
     attached hereto, at the office or agency of the Company referred to in
     Paragraph 8(e) below; provided, however, that any transfer or assignment
     shall be subject to the conditions set forth in Paragraph 8(f) hereof and
     to the applicable provisions of the Securities Purchase Agreement and the
     Settlement Agreement. Until due presentment for registration of transfer on
     the books of the Company, the Company may treat the registered holder
     hereof as the owner and holder hereof for all purposes, and the Company
     shall not be affected by any notice to the contrary. Notwithstanding
     anything to the contrary contained herein, the registration rights
     described in Paragraph 9 are assignable only in accordance with the
     provisions of that certain Registration Rights Agreement, dated as of
     December 11, 2000, by and among the Company and Invest, as amended by that
     certain Settlement Agreement and Mutual Release of Claims, dated as of
     February 6, 2001 (the "Registration Rights Agreement").

          (b) WARRANT EXCHANGEABLE FOR DIFFERENT DENOMINATIONS. This Warrant is
     exchangeable, upon the surrender hereof by the holder hereof at the office
     or agency of the Company referred to in Paragraph 8(e) below, for new
     Warrants of like tenor representing in the aggregate the right to purchase
     the number of shares of Common Stock which may be purchased hereunder, each
     of such new Warrants to represent the right to purchase such number of
     shares as shall be designated by the holder hereof at the time of such
     surrender.

          (c) REPLACEMENT OF WARRANT. Upon receipt of evidence reasonably
     satisfactory to the Company of the loss, theft, destruction, or mutilation
     of this Warrant and, in the case of any such loss, theft, or destruction,
     upon delivery of an indemnity agreement reasonably satisfactory in form and
     amount to the Company, or, in the case of any such mutilation, upon
     surrender and cancellation of this Warrant, the Company, at its expense,
     will execute and deliver, in lieu thereof, a new Warrant of like tenor.

                                      -11-
<PAGE>

          (d) CANCELLATION; PAYMENT OF EXPENSES. Upon the surrender of this
     Warrant in connection with any transfer, exchange, or replacement as
     provided in this Paragraph 8, this Warrant shall be promptly canceled by
     the Company. The Company shall pay all taxes (other than securities
     transfer taxes) and all other expenses (other than legal expenses, if any,
     incurred by the holder or transferees) and charges payable in connection
     with the preparation, execution, and delivery of Warrants pursuant to this
     Paragraph 8.

          (e) REGISTER. The Company shall maintain, at its principal executive
     offices (or such other office or agency of the Company as it may designate
     by notice to the holder hereof), a register for this Warrant, in which the
     Company shall record the name and address of the person in whose name this
     Warrant has been issued, as well as the name and address of each transferee
     and each prior owner of this Warrant.

          (f) EXERCISE OR TRANSFER WITHOUT REGISTRATION. If, at the time of the
     surrender of this Warrant in connection with any exercise, transfer, or
     exchange of this Warrant, this Warrant (or, in the case of any exercise,
     the Warrant Shares issuable hereunder), shall not be registered for resale
     under the Securities Act and under applicable state securities or blue sky
     laws, the Company may require, as a condition of allowing such exercise,
     transfer, or exchange, (i) that the holder or transferee of this Warrant,
     as the case may be, furnish to the Company a written opinion of counsel,
     which opinion and counsel are acceptable to the Company, to the effect that
     such exercise, transfer, or exchange may be made without registration under
     said Act and under applicable state securities or blue sky laws, (ii) that
     the holder or transferee execute and deliver to the Company an investment
     letter in form and substance acceptable to the Company and (iii) that the
     transferee be an "accredited investor" as defined in Rule 501(a)
     promulgated under the Securities Act; provided that no such opinion, letter
     or status as an "accredited investor" shall be required in connection with
     a transfer pursuant to Rule 144 under the Securities Act. The first holder
     of this Warrant, by taking and holding the same, represents to the Company
     that such holder is acquiring this Warrant for investment and not with a
     view to the distribution thereof.

assignees thereof) is entitled to the benefit of such registration rights in

courier upon deposit with the United States Post Office or such overnight mail
courier, if postage is prepaid and the mailing is properly addressed, as the
case may be.

     12. MISCELLANEOUS.

          (a) AMENDMENTS. This Warrant and any provision hereof may only be
     amended by an instrument in writing signed by the Company and the holder
     hereof.

          (b) DESCRIPTIVE HEADINGS. The descriptive headings of the several
     paragraphs of this Warrant are inserted for purposes of reference only, and
     shall not affect the meaning or construction of any of the provisions
     hereof.

          (c) REMEDIES CUMULATIVE. The remedies provided in this Warrant shall
     be cumulative and in addition to all other remedies available under this
     Warrant, at law or in equity (including a decree of specific performance
     and/or other injunctive relief), no remedy contained herein shall be deemed
     a waiver of compliance giving rise to such remedy and nothing herein

                                      -13-
<PAGE>

     shall limit holder's right to pursue actual damages for any failure by the
     Company to comply with the terms of this Warrant. The Company acknowledges
     that a breach by it of its obligations hereunder will cause irreparable
     harm to holder and that the remedy at law for any such breach may be
     inadequate. The Company therefore agrees, in the event of any such breach
     or threatened breach, holder shall be entitled, in addition to all other
     available remedies, to an injunction restraining any breach, without the
     necessity of showing economic loss and without any bond or other security
     being required.

                                WITNESSETH, THAT:

      1. DEMISED PREMISES. Landlord, for the Term and subject to the provisions
and conditions hereof, leases to Tenant and Tenant accepts from Landlord, the
Demised Premises, together with the non-exclusive right to use the common areas
and facilities of the Buildings in common with the other tenants of the
Building. Tenant shall not use or occupy, or permit or suffer to be used or
occupied, the Demised Premises or any part thereof, other than for the Permitted
Use.

      2. TERM.

            (a) The first lease year of the Term shall commence on the
Commencement Date and shall end on (i) the day immediately preceding the first
anniversary of the Commencement Date, if the Commencement Date is the first day
of the month, or (ii) the last day of the month in which the first anniversary
of the Commencement Date occurs, if the Commencement Date is any day other than
the first day of a calendar month. Each lease year after the first lease year
shall be a consecutive twelve (12) month period commencing on the first day of
the calendar month immediately following the preceding lease year.

            (b) Tenant shall have the right and option to extend the Term for
two (2) additional periods of three (3) years (the "Extension Terms") commencing
upon the expiration of the original Term referred to in the Fundamental Lease
Provisions, provided that Tenant shall give Landlord notice of Tenant's
irrevocable exercise of such option at least six (6) months prior to the
expiration of the then current Term and provided further that Tenant shall not
be in default at either the time of giving such notice or at the time of the
commencement of the Extension Term in the performance or observance of any of
the terms and provisions of this Lease on the part of the Tenant to be performed
or observed. Prior to the exercise by Tenant of such option, the expression
"Term" shall mean the then current Term as may have been previously extended,
and after the exercise by Tenant of such option, the expression "Term" shall
mean the Term as it has been extended by the applicable Extension Term. Except
as expressly otherwise provided in the following paragraph, all the terms,
covenants, conditions, provisions and agreements in the Lease contained shall be
applicable to the Extension Term. If Tenant shall give notice of its exercise of
said option to extend in the manner and within the time period provided
aforesaid, the Term shall be extended upon the giving of such notice without the
requirement of any further action on the part of either Landlord or Tenant.

            (c) The Annual Base Rent payable during an Extension Term shall be
the greater of: the Fair Market Rent for the Demised Premises, as determined
below, for the applicable Extension Term, and (ii) the Annual Base Rent in
effect during the final lease year of the then current Term. As used herein, the
term "Fair Market Rent" shall mean the average of the annual rental rates then
being charged for comparable space in the Building or, if no comparable space
exists in the Building, for "Class A" office space in the Conshohocken market,
for leases commencing on or about the commencement of the Extension Term, taking
into consideration the use, location and floor level of the applicable building,
leasehold improvements or allowances provided, rental concessions, the term of
the lease under consideration, the extent of services provided thereunder, the
creditworthiness of Tenant, and other adjustments to the base rental and any
other relevant term or condition in making such evaluation. Landlord shall
determine the Fair Market Rent using its good faith judgment and shall provide
written notice of such rate within fifteen (15) days after Tenant's exercise
notice pursuant to this Section. Tenant shall thereupon have the following
options: (i) to accept such

                                       5
<PAGE>

proposed "Fair Market Rent", (ii) to decline to exercise its renewal option, or
(iii) to notify Landlord in writing that Tenant objects to the proposed rental
rate. Tenant must provide Landlord with written notification of its election
within fifteen (15) days after Tenant's receipt of Landlord's notice, otherwise
Tenant shall be deemed to have elected clause (ii) above, in which event Tenant
shall be deemed to have rescinded its exercise notice and this Lease shall
expire on the Expiration Date as if Tenant had not elected to exercise its
renewal option hereunder. If Tenant objects to Landlord's proposed "Fair Market
Rent" in accordance with clause (iii) above, Landlord and Tenant shall attempt
to negotiate a mutually acceptable rental rate within fifteen (15) days
following notification by Tenant, and if such negotiations have not been
concluded within such fifteen (15) day period, either party may require
determination of the Fair Market Rent for the Extension Term by giving written
notice to the other no later than ten (10) days after the expiration of such
fifteen (15) day period, which notice shall designate a reputable, independent
real estate appraiser, broker or consultant experienced in office leasing in the
local metropolitan area, each of which, for purposes of this Section, is
referred to as an "appraiser." Within ten (10) days after receipt of such
notice, the other party to this Lease shall select an appraiser meeting the
aforesaid requirements and give written notice of such selection to the
initiating party. If the two (2) appraisers fail to agree upon the Fair Market
Rent within ten (10) days after selection of the second appraiser, the two (2)
appraisers shall select a third (3rd) appraiser meeting the foregoing
requirements to determine the Fair Market Rent within ten (10) days after the
appointment of the third (3rd) appraiser. The Fair Market Rent applicable to the
Extension Term shall equal the arithmetic average of such three (3)
determinations; provided, however, that if one (1) appraiser's determination
deviates by more than five percent (5%) from the median of the three (3)
determinations, the Fair Market Rent shall be an amount equal to the average of
the other two (2) determinations. The determination of Fair Market Rent shall be
final, binding and conclusive on Landlord and Tenant

      3. TENANT IMPROVEMENTS.

            (a) Landlord, at its sole expense, shall (i) complete construction
of the bathrooms on the third and fourth floors of the Building (including one
(1) shower per bathroom) and (ii) install all main trunk lines for the HVAC
systems in the Demised Premises, each in accordance with Building standards
(collectively, the "Landlord's Work"). Except for the Landlord's Work Landlord
shall have no obligation to perform any improvements to the Demised Premises to
prepare the space for Tenant's occupancy, and Tenant acknowledges that Tenant
has inspected the Demised Premises and accepts the same in its "AS IS"
condition, without any representation or warranty by Landlord.

            (b) Except for the Landlord's Work, Tenant shall perform, at its
sole cost and expense, all work which Tenant deems necessary or desirable to
prepare the space for Tenant's initial occupancy (collectively, the "Tenant
Improvements"), which Tenant Improvements shall be subject to the prior written
approval of Landlord. All work shall be performed in a good and workmanlike
manner and in accordance with all applicable laws. Prior to the commencement of
any work within the Demised Premises, Tenant shall submit to Landlord, for
Landlord's prior approval, proposed plans and specifications (the "Proposed
Tenant's Plans") for Tenant's proposed improvements to the Demised Premises,
which plans shall be prepared by a registered architect licensed to do business
within the State in which the Property is located. The Proposed Tenant's Plans
shall include all information and specifications necessary for Landlord to fully
review the work described therein and shall conform to all applicable laws and
requirements of public authorities and insurance underwriters' requirements.
Landlord shall review and either approve or disapprove of the Proposed Tenant's
Plans within five (5) business days after receipt thereof from Tenant. If
Landlord disapproves the Proposed Tenant's

                                       6
<PAGE>

Plans, Landlord shall state specifically the reasons for such disapproval, and
Tenant shall cause its architects to promptly make any changes in the Proposed
Tenant's Plans reasonably required by Landlord. All contractors utilized by
Tenant for the performance of the Tenant Improvements shall be subject to the
prior written approval of Landlord.

            (c) All subsequent changes in the Tenant's Plans shall be subject to
the approval of Landlord. If Landlord approves any change in the Tenant's Plans,
Tenant shall construct, at Tenant's sole cost and expense, the Tenant
Improvements in accordance with such change.

            (d) Provided that Tenant is not in default of any of its obligations
hereunder, Landlord shall provide Tenant with a construction allowance (the
"Tenant Improvement Allowance") of Thirteen Dollars ($13.00) per rentable square
foot of the Demised Premises, which shall be applied solely against Tenant's
Costs for the Tenant Improvements and for no other purpose. The Tenant
Improvement Allowance shall be payable on the Commencement Date. "Tenant's
Costs" shall mean Tenant's out-of-pocket contract or purchase price(s) for
materials, components, labor and services incurred by tenant in connection with
the Tenant Improvements. Prior to payment of the Tenant Improvement Allowance,
the total amount of Tenant's Costs shall be subject to examination by Landlord,
and Tenant shall provide Landlord with copies of all invoices and other backup
documentation reasonably requested by Landlord relative thereto. In the event
that Tenant's Costs exceed the amount of the Tenant Improvement Allowance,
Tenant shall be solely responsible for such excess costs.

            (e) Landlord acknowledges that Tenant shall have the right to use
any existing materials currently located within the Demised Premises as of the
date hereof in connection with its build-out of the Tenant Improvements.

      4. DELAY IN POSSESSION. INTENTIONALLY OMITTED.

      5. RENT.

            (a) During the Term of this Lease, Tenant shall pay to Landlord the
Annual Base Rent in the amount set forth in Section 10 of the Fundamental Lease
Provisions. Such Base Rent shall be payable in equal monthly installments in
advance on the first day of each calendar month.

            (b) The term "rent" as used in this Lease shall mean the Annual Base
Rent, Tenant's Share of Operating Expenses (including, without limitation,
Taxes) and all other additional rent or other sums payable by Tenant to Landlord
under this Lease, all of which shall be deemed "rent" for purposes of Landlord's
rights and remedies with respect thereto.

            (c) The first installment of rent shall be payable on the
Commencement Date. If the Term begins on a day other than the first day of a
month, rent from such day until the first day of the following month shall be
prorated on a per diem basis for each day of such partial month, and the
installment of rent paid at execution hereof shall be applied to the rent due
for the first full calendar month of the term hereof.

            (d) All rent and other sums due to Landlord hereunder shall be
payable to Landlord c/o Landlord's Property Manager at the address specified in
Section 12 of the Fundamental Lease Provisions, or to such other party or at
such other address as Landlord may designate, from time to time, by written
notice to Tenant, without demand and without deduction,

                                       7
<PAGE>

set-off or counterclaim (except to the extent demand, notice or set-off shall be
expressly provided for herein).

            (e) If Landlord, at any time or times, shall accept said rent or any
other sum due to it hereunder after the same shall become due and payable, such
acceptance shall not excuse delay upon subsequent occasions, or constitute or be
construed as, a waiver of any of Landlord's rights hereunder.

      6. SECURITY DEPOSIT/LETTER OF CREDIT.

            (a) As additional security for the full and prompt performance by
Tenant of the terms and covenants of this Lease, Tenant shall deliver to
Landlord simultaneously with the execution of this Lease an unconditional and
irrevocable letter of credit (the "Letter of Credit") in the amount of the
Security Deposit (as defined in Section 11 of the Fundamental Lease Provisions),
which Letter of Credit shall be in form and substance satisfactory to Landlord
and shall be issued by a bank satisfactory to Landlord. In such event, the first
such Letter of Credit shall expire no earlier than the first anniversary of the
Commencement Date and all subsequent Letters of Credit (which shall meet all of
the requirements set forth in the preceding sentence) shall expire no earlier
than twelve (12) months after the expiration of the then outstanding and
expiring Letter of Credit. Subject to subsection (b) below, Tenant shall ensure
at all times during the Term of this Lease, an unexpired Letter of Credit in the
face amount of the Security Deposit (as such amount may be reduced pursuant to
subparagraph (b) below) or cash in such amount shall be in the possession of
Landlord. During the Term, Tenant shall deliver a replacement Letter of Credit
to Landlord no later than thirty (30) days prior to the expiration date of the
then outstanding and expiring Letter of Credit; provided, however, that the
replacement Letter of Credit is not required to have an effective date sooner
than the expiration date of the then-existing Letter of Credit. Failure by
Tenant to deliver any replacement Letter of Credit as required above shall
entitle Landlord to draw upon the outstanding Letter of Credit and retain the
entire proceeds thereof for application as the Security Deposit hereunder.
Tenant shall not be entitled to interest for any period during which Landlord is
holding cash as the Security Deposit nor shall Landlord be required to keep such
cash Security Deposit separate from its general funds. Each Letter of Credit
shall be for the benefit of Landlord, its successors and assigns to draw from
time to time under the Letter of Credit in portions or in whole upon
presentation of a sight draft and statement by Landlord that Landlord is
entitled to draw thereunder pursuant to the terms and provisions of this Lease.
Landlord may assign and deliver the Letter of Credit to any purchaser or
successor of Landlord's interest in the Building, in which event Landlord shall
be discharged from any further liability with respect to the Letter of Credit.

            (b) Provided that Tenant is not then in default, the Security
Deposit shall be reduced by the amount of One Hundred Twenty Five Thousand
Dollars ($125,000.00) as of each of the first four (4) anniversaries of the
Commencement Date and, provided Tenant is not then in default, the Security
Deposit shall be reduced to Zero Dollars ($0.00) as of the commencement of the
fifth (5th) lease year.

            (c) If at any time during the Term, Tenant defaults in the
performance of any of its obligations hereunder, Landlord shall have the right
to draw upon the Letter of Credit ( or, if a cash Security Deposit, to apply
such cash) to satisfy such obligations including, without limitation, the
Accelerated Rent Component and any damages to which Landlord is entitled
pursuant to Section 15 hereof. If any portion of the Letter of Credit (or cash
Security Deposit) is used, applied or retained by Landlord, Tenant shall, upon
demand, reinstate the Letter of Credit or cash in the full amount of the
Security Deposit (and thereafter there shall be no further

                                       8
<PAGE>

reductions of the security Deposit pursuant to subparagraph (b) above), and
Tenant's failure to do so shall constitute a default under this Lease for which
Tenant shall not be entitled to notice or an opporturiity to cure The Security
Deposit shall not be construed as liquidated damages hereunder, and if
Landlord's claims hereunder exceed the amount of the Security Deposit, Tenant
shall remain liable for the balance of such claims.

      7. PAYMENT OF OPERATING EXPENSES.

annual amortized portion of such expense together with an interest factor equal
to the prime rate of interest as published from time to time in The Wall Street
Journal shall be included in annual Operating Expenses; (iii) Rentals for items
which if purchased, rather than rented, would constitute a capital cost; (iv)
any charge for depreciation, amortization and interest on encumbrances or ground

            (b) In determining Operating Expenses for any year, if less than
ninety-five percent (95%) of the Building rentable area shall have been occupied
by tenants at any time during such year, Operating Expenses shall be deemed for
such year to be an amount equal to the like expenses which Landlord reasonably
determines would normally had been incurred had such occupancy been ninety-five
percent (95%) throughout such year.

            (c) For and with respect to each calendar year of the Term
(including any renewals or extensions thereof), there shall accrue, as
additional rent, an amount ("Tenant's Share") equal to the positive difference,
if any, between (A) Tenant's Fraction of Operating

                                       10

calendar year included within the beginning and end of the Term).

            (d) Landlord shall furnish to Tenant as soon as reasonably possible
after the beginning of each calendar year of the Term:

                  (i) A statement (the "Expense Statement") setting forth (1)
Operating Expenses for the previous calendar year, and (2) Tenant's Share of
Operating Expenses for the previous calendar year; and

                  (ii) A statement of Landlord's good faith estimate of
Operating Expenses, and the amount of Tenant's Share thereof (the "Estimated
Share"), for the current calendar year.

            (e) Within thirty (30) days after Tenant receives the Expense
Statement, Tenant shall pay to Landlord the difference, if positive, between the
Tenant's Share of Operating Expenses for such previous year and the actual
payments made by Tenant during such calendar year, or if the actual payments
exceed Tenant's Share of Operating Expenses for such previous year, Tenant shall
receive a credit against the next payment(s) of Operating Expenses falling due
or, if the Lease shall have expired, a refund of such overpayment delivered with
such Expense Statement.

            (f) Upon the written request of Tenant delivered to Landlord within
ninety (90) days after delivery of the Expense Statement, Landlord shall give
Tenant the opportunity during normal business hours to review Landlord's books
and records relating to Operating Expenses, provided Tenant thereafter
diligently and promptly completes such inspection, and such inspection privilege
shall not delay Tenant's obligation to pay on account all sums due pursuant to
such Expense Statement. Unless Tenant, within ninety (90) days after any Expense
Statement is furnished, shall give notice to Landlord that Tenant disputes said
statement, specifying in detail the basis for such dispute, each Expense
Statement furnished to Tenant by Landlord under this Section shall be
conclusively binding upon Tenant as to the Operating Expenses due from Tenant
for the period represented thereby; provided, however, that additional amounts
due may be required to be paid by any supplemental statement furnished by
Landlord. In the event that Tenant timely disputes such Expense Statement and
the dispute is not amicably resolved within ninety (90) days after Tenant's
notice of dispute, then either party may refer the dispute to an independent
certified public accounting firm mutually acceptable to Landlord and Tenant, and
the determination of such accounting firm shall be final, binding and conclusive
on Landlord and Tenant. Tenant agrees to pay for the cost of such audit by said
accounting firm unless it is determined that Landlord's original determination
of the actual Operating Expenses was in error by more than seven percent (7%),
in which event Landlord shall pay the cost of such audit. Pending resolution of
any dispute, Tenant shall pay the additional rent in accordance with the Expense
Statement furnished by Landlord.

            (g) Beginning with the next installment of Base Rent due after
delivery of the statement of Tenant's Estimated Share, Tenant shall pay to
Landlord, on account of its share of Operating Expenses, one-twelfth (1/12) of
the Estimated Share multiplied by the number of full or partial calendar months
elapsed during the current calendar year up to and including the month payment
is made (less any amounts previously paid by Tenant on account of Operating
Expenses for such period).

                                       11
<PAGE>

            (g) On the first day of each succeeding month up to the time Tenant
shall receive a new statement of Tenant's Estimated Share, Tenant shall pay to
Landlord, on account of its share of Operating Expenses, one-twelfth of the then
current Estimated Share. Any payment due from Tenant to Landlord on account of
Operating Expenses not yet determined as of the expiration of the Term shall be
made within thirty (30) days after submission to Tenant of the next Expense
Statement, which obligation shall survive the expiration or earlier termination
of this Lease.

      8. UTILITIES SEPARATELY CHARGED TO DEMISED PREMISES. Tenant shall be
responsible for all utilities (including gas and electric) which are consumed
within the Demised Premises. If a separate meter is installed, Tenant shall pay
for the consumption of such utilities based on its metered usage. If no meter is
installed, Tenant shall pay a pro-rata share of any utility charges covering the
Demised Premises and other areas of the Building, which pro-rata share shall be
based on the percentage which the Tenant's RSF bears to the square footage of
the areas of the Building serviced by such utility. Tenant shall pay all utility
bills within ten (10) days after receipt by Tenant. Landlord shall have the
right, to be exercised by written notice to Tenant, to direct Tenant to contract
directly with the utility provider supplying electricity to the Building, in
which event Tenant shall pay all charges therefor directly to the utility
provider, except that Landlord shall pay for any separate meter installation
required in connection such election by Landlord. Landlord shall at all times
have the exclusive right to select the provider(s) of utility service to the
Building and the Property; however, in the event that any telecommunications
supplier is able to supply telecommunications services directly to the Premises,
Tenant shall have the right to contract directly for such services at Tenant's
sole cost and expense.

      9. SERVICES. Landlord agrees that it shall:

            (a) Provide water for drinking, lavatory and toilet purposes drawn
through fixtures installed by Landlord;

            (b) Furnish heat, ventilation and air-conditioning to the Demised
Premises during Business Hours;

            (c) Furnish electricity to the Demised Premises for ordinary office
purposes, including general lighting and personal computers, provided, however,
that Landlord shall have no obligation to supply in excess of nine (9) watts per
rentable square foot of the Demised Premises;

            (d) Provide janitorial services in accordance with Landlord's
building standard janitorial specifications, attached hereto as Exhibit "D". Any
and all additional or specialized janitorial service desired by Tenant shall be
contracted for by Tenant directly and the cost and payment thereof shall be the
sole responsibility of Tenant; and

            (e) Provide Tenant with standard signage on the directory in the
Building lobby.

            The cost of the foregoing services shall be included in Operating
Expenses. It is understood that Landlord does not warrant that any of the
services referred to in this Section will be free from interruption from causes
beyond the reasonable control of Landlord. No interruption of service shall ever
be deemed an eviction or disturbance of Tenant's use and possession of the
Demised Premises or any part thereof or render Landlord liable to Tenant for
damages, permit Tenant to abate rent or otherwise relieve Tenant from
performance of Tenant's

                                       12
<PAGE>

obligations under this Lease. Notwithstanding the foregoing, in the event that
any interruption of utilities caused by Landlord's negligence renders the
Demised Premises untenantable for a period of five (5) or more consecutive
business days after written notice thereof to Landlord, then, to the extent
that the Demised Premises are rendered untenantable, Tenant shall be entitled to
a proportionate abatement of rent until such time as the Demised Premises are
thereafter rendered tenantable.

      10. CARE OF DEMISED PREMISES. Tenant agrees, on behalf of itself, its
employees and agents that it shall:

            (a) Comply at all times with any and all federal, state and local
statutes, regulations, ordinances, and other requirements of any of the
constituted public authorities relating to its use and occupancy of the Demised
Premises.

            (b) Give Landlord access to the Demised Premises at all reasonable
times and upon reasonable notice (except in the event of emergency), without
charge or diminution of rent, to enable Landlord (i) to examine the same and to
make such repairs, additions and alterations as Landlord may be permitted to
make hereunder or as Landlord may deem advisable for the preservation of the
integrity, safety and good order of the Building or any part thereof; and (ii)
to show the Demised Premises to prospective mortgagees and purchasers and,
during the six (6) months prior to expiration of the Term, to prospective
tenants;

            (c) Reasonable wear and tear and damage by casualty excepted,
maintain, repair and replace the interior, non-structural portions of the
Demised Premises in good order and repair as and when needed, and replace all
glass broken by Tenant, its agents, employees or invitees with glass of the same
quality as that broken, except for glass broken by fire and extended
coverage-type risks, and commit no waste in the Demised Premises;

            (d) Upon the expiration or earlier termination of this Lease, remove
Tenant's goods and effects and those of any other person claiming under Tenant,
and quit and deliver up the Demised Premises to Landlord peaceably and quietly
in as good order and condition as existed at the inception of the Term, together
with any alterations approved by Landlord, reasonable wear and tear, damage from
fire and casualty excepted. Goods and effects not removed by Tenant at the
termination of this Lease, however terminated, shall be considered abandoned
and Landlord may dispose of and/or store the same as it deems expedient, the
cost thereof to be charged to Tenant;

            (e) Not place signs on the Demised Premises except for (i) signs
located entirely within the Demised Premises and which are not visible from the
exterior of the Demised Premises, and (ii) signs on doors provided that the
lettering and text are reasonably approved by Landlord;

            (f) Not overload, damage or deface the Demised Premises or do any
act which might make void or voidable any insurance on the Demised Premises or
the Building or which may render an increased or extra premium payable for
insurance (and without prejudice to any right or remedy of Landlord regarding
this subparagraph, Landlord shall have the right to collect from Tenant, upon
demand, any such increase or extra premium). Tenant shall maintain at its own
sole cost adequate insurance coverage for the full replacement value of all of
its

                                       13
<PAGE>

equipment, furniture, supplies and fixtures and provide Landlord with
certificates evidencing such coverage;

            (g) Not make any alteration of or addition to the Demised Premises
without the prior written approval of Landlord which approval shall not be
unreasonably withheld or delayed. Tenant shall not be required to obtain the
approval of Landlord for interior, nonstructural alterations of a decorative
nature that do not exceed, more than $50,000 in the aggregate;

            (h) Not install any equipment of any kind whatsoever which might
necessitate any changes, replacements or additions to any of the heating,
ventilating, air-conditioning, electric, sanitary, elevator or other systems
serving the Demised Premises or any other portion of the Building, or to any of
the services required of Landlord under this Lease, without the prior written
approval of Landlord, which approval shall not be unreasonably withheld or
delayed. In the event such consent is granted, such replacements, changes or
additions shall be paid for by Tenant at Tenant's sole cost and expense. If
Landlord notifies Tenant at the time of such approval that Landlord shall so
require, then at the expiration or earlier termination of this Lease, Tenant
shall pay Landlord's cost of restoring such systems to their condition prior to
such replacements, changes or additions;

            (i) Not install or authorize the installation of any coin operated
vending machine, except for the dispensing of cigarettes, coffee, and similar
items to the employees of Tenant for consumption upon the Demised Premises; and

            (j) Observe the rules and regulations annexed hereto as Exhibit "C,"
as Landlord may from time to time amend the same, for the general safety,
comfort and convenience of Landlord, occupants and tenants of the Building.

      11. MECHANIC'S LIEN. Tenant shall, within ten (10) days after notice from
Landlord, discharge any mechanic's lien for materials or labor claimed to have
been furnished to the Demised Premises on Tenant's behalf (except for work
contracted for by Landlord) and shall indemnify and hold harmless Landlord from
any loss incurred in connection therewith.

      12. REPAIRS AND MAINTENANCE. Landlord shall keep and maintain the public
areas of the Building clean and in good working order. Landlord shall further
make, or cause to be made, all necessary repairs to the structure and exterior
of the Building, as well as to the mechanical, HVAC, electrical and plumbing
systems servicing Building. The cost of the foregoing maintenance and repairs
shall be included in Operating Expenses to the extent set forth herein.
Notwithstanding the foregoing, all repairs made necessary by Tenant's specific
use, occupancy or alteration of the Building, or by the negligent acts of
Tenant, its agents, employees or invitees, shall be made at the sole cost and
expense of Tenant.

      13. SUBLETTING AND ASSIGNING.

            (a) Tenant shall not assign this Lease or sublet all or any portion
of the Demised Premises, whether voluntarily or by operation of law, without
first obtaining Landlord's prior written consent thereto, which consent shall
not be unreasonably withheld, conditioned or delayed Tenant acknowledges that it
shall be reasonable for Landlord to withhold its consent if, inter alia, the
reputation or financial responsibility of a proposed assignee or subtenant is
unsatisfactory to Landlord, or if the proposed sublease or assignment is to a
tenant of the Building and alternative space is available for lease in the
Building, or if such subtenant's or assignee's

                                       14
<PAGE>

business is not consonant with that of the other tenants of the Building. In
addition, Tenant shall not mortgage, pledge or hypothecate this Lease. Any
assignment, sublease, mortgage, pledge or hypothecation in violation of this
Section shall be void at the option of Landlord and shall constitute a default
hereunder without the opportunity for notice or cure by Tenant. Landlord
acknowledges that Tenant intends to initially sublet up to 21,000 square feet in
the Premises; Landlord agrees that it shall not unreasonably withhold, condition
or delay its consent to such initial subletting.

            (b) Subject to the provisions of the following sentence, a transfer
or sale by Tenant of a majority of the voting shares, partnership interests or
other controlling interests in Tenant shall be deemed an assignment of this
Lease by Tenant requiring Landlord's prior written consent pursuant to
subparagraph (a) above. Notwithstanding the foregoing, so long as Tenant is not
in default under this Lease, Tenant shall have the right, without Landlord's
consent, to sublet all or a portion of the Demised Premises or to assign the
Lease to any company which (i) is an Affiliate of Tenant, or (ii) merges with,
combines with or is the result of such combination, or purchases all or
substantially all the assets or a majority of the voting shares or interests of
Tenant, provided that after such merger, combination or purchase such entity has
a net worth not less than the then net worth of Tenant immediately prior to such
merger, combination or purchase. As used herein, "Affiliate" shall mean any
corporation which controls, is controlled by or is under common control with
Tenant, and "control" shall mean the direct ownership of more than fifty percent
(50%) of the voting shares, partnership interests or other controlling interests
of the applicable entity. Tenant shall deliver to Landlord written notice of
such assignment or subletting promptly upon the consummation of any such
transaction. The public issuance or trading of shares in Tenant shall not be
construed as affecting the assignment of this Lease.

            (c) Notwithstanding the foregoing, no subletting or assignment with
or without Landlord's consent shall in any way relieve or release Tenant from
liability for the performance of all terms, covenants and conditions of this
Lease. Furthermore, no assignment will be valid unless the assignee shall
execute and deliver to Landlord an assumption of liability agreement in form
satisfactory to Landlord, including an assumption by the assignee of all of the
obligations of Tenant and the assignee's ratification of and agreement to be
bound by all the provisions of this Lease, and no subletting will be valid
unless Landlord shall have approved the sublease in writing, which sublease must
include a provision by which the subtenant agrees to be bound by the
incorporation of applicable provisions of this Lease.

            (d) Tenant shall pay to Landlord, as additional rent hereunder, 50%
of all subrents or other sums or economic consideration received by Tenant
(after deducting Tenant's reasonable costs of reletting, including but not
limited to commissions, legal fees, tenant improvements and concessions),
whether denominated as rentals or otherwise, in excess of the monthly sums which
Tenant is required to pay under this Lease.

      14. FIRE OR CASUALTY. In the event that the whole or a substantial part of
the Building or the Demised Premises is damaged or destroyed by fire or other
casualty, then, within forty-five (45) days after the date that Landlord
receives notice of such fire or other casualty, Landlord shall provide written
notice to Tenant as to whether Landlord intends to repair or rebuild and the
estimated time period for the completion thereof. In the event that Landlord's
notice provides that the repairs to the Demised Premises shall require more than
two hundred seventy (270) days to complete, then Tenant shall have the right to
terminate this Lease by providing written notice thereof to Landlord within
thirty days (30) after receipt of Landlord's notice. In the event that Landlord
elects to repair or rebuild (and Tenant does not have the right to, or has
elected not to, terminate this Lease in accordance with the foregoing

                                       15
<PAGE>

sentence), Landlord shall thereupon cause the damage (excepting, however,
Tenant's furniture, fixtures, equipment and improvements, which shall be
Tenant's responsibility to restore) to be repaired with reasonable speed,
subject to delays beyond the reasonable control of Landlord. In the event the
damage shall be so extensive that Landlord shall decide not to repair or
rebuild, or if any mortgagee, having the right to do so, shall direct that the
insurance proceeds are to be applied to reduce the mortgage debt rather than to
the repair of such damage, this Lease shall, be terminated effective as of the
date of casualty. To the extent and for the time that the Demised Premises are
rendered untenantable on account of fire or other casualty, the rent shall
proportionately abate.

      15. EMINENT DOMAIN. If the whole or a substantial part of the Building is
taken or condemned for a public or quasi-public use under any statute or by
right of eminent domain by any competent authority or sold in lieu of such
taking or condemnation, such that in the opinion of Landlord the Building is not
economically operable as before without substantial alteration or
reconstruction, this Lease shall automatically terminate on the date that the
right to possession shall vest in the condemning authority (the "Taking Date"),
with rent being adjusted to said Taking Date, and Tenant shall have no claim
against Landlord for the value of any unexpired term of this Lease. Tenant shall
have no claim against Landlord and no claim or right to any portion of any
amount that may be awarded as damages or paid as a result of any taking,
condemnation or purchase in lieu thereof; all rights of Tenant thereto are
hereby assigned by Tenant to Landlord. If any part of the Demised Premises is so
taken or condemned, this Lease shall automatically terminate as to the portion
of the Demised Premises so taken or condemned, as of the Taking Date, and this
Lease shall continue in full force as to the remainder of the Demised Premises,
with rent abating only to the extent of the Demised Premises so taken or
condemned; provided, however, that if the remaining portion of the Demised
Premises is no longer suitable for the Permitted Use, then Tenant shall have the
right to terminate this Lease by providing written notice thereof to Landlord
within thirty (30) days after the Taking Date. Nothing in this section shall be
construed to prevent Tenant from filing a separate claim with the condemning
authority for Tenant's costs and losses associated with any such taking,
provided that the same does not diminish or otherwise adversely affect any claim
by Landlord.

      16. INSOLVENCY. (a) The appointment of a receiver or trustee to take
possession of all or a portion of the assets of Tenant, or (b) an assignment by
Tenant for the benefit of creditors, or (c) the institution by or against Tenant
of any proceedings for bankruptcy or reorganization under any state or federal
law (unless in the case of involuntary proceedings, the same shall be dismissed
within sixty (60) days after institution), or (d) any execution issued against
Tenant which is not stayed or discharged within thirty (30) days after issuance
of any execution sale of the assets of Tenant, shall constitute a breach of this
Lease by Tenant. Landlord in the event of such a breach, shall have, without
need of further notice, the rights enumerated in Section 17 herein.

      17. DEFAULT.

            (a) If Tenant shall fail to pay rent or any other sum payable to
Landlord hereunder when due and such failure continues for more than five
business (5) days after written notice thereof from Landlord to Tenant
(provided, however, that Landlord shall not be required to provide notice to
Tenant more than two times during any twelve month period), or if Tenant shall
fail to perform or observe any of the other covenants, terms or conditions
contained in this Lease and such failure continues for more than thirty (30)
days after written notice thereof from Landlord (or such longer period as is
reasonably required to correct any such default, provided Tenant promptly
commences and diligently continues to effectuate a cure, but in any

                                       16
<PAGE>

event within ninety (90) days after written notice thereof by Landlord), or if
any of the events specified in Section 16 occur, or if Tenant abandons the
Demised Premises during the term hereof or removes or manifests an intention to
remove any of Tenant's goods or property therefrom other than in the ordinary
and usual course of Tenant's business, then and in any of said cases
(notwithstanding any former breach of covenant or waiver thereof in a former
instance), Landlord, in addition to all other rights and remedies available to
it by law or equity or by any other provisions hereof, may at any time
thereafter:

                  (i) upon three (3) days notice to Tenant, declare to be
immediately due and payable, a sum equal to the Accelerated Rent Component (as
hereinafter defined), and Tenant shall remain liable to Landlord as hereinafter
provided; and/or

                  (ii) whether or not Landlord has elected to recover the
Accelerated Rent Component, terminate this Lease on at least five (5) days
notice to Tenant and, on the date specified in said notice, this Lease and the
term hereby demised and all rights of Tenant hereunder shall expire and
terminate and Tenant shall thereupon quit and surrender possession of the
Demised Premised to Landlord in the condition elsewhere herein required and
Tenant shall remain liable to Landlord as hereinafter provided.

            (b) For purposes herein, the Accelerated Rent Component shall mean
the aggregate of:

                  (i) all rent and other charges, payments, costs and expenses
due from Tenant to Landlord and in arrears at the time of the election of
Landlord to recover the Accelerated Rent Component; and

                  (ii) the Annual Base Rent reserved for the then entire
unexpired balance of the Term (taken without regard to any early termination of
the term by virtue of any default), plus all other charges, payments, costs and
expenses herein agreed to be paid by Tenant up to the end of the Term which
shall be capable of precise determination at the time of Landlord's election to
recover the Accelerated Rent Component, discounted to present value based upon a
then commercially reasonable discount rate; and

                  (iii) Landlord's good faith estimate of all charges, payments,
costs and expenses herein agreed to be paid by Tenant up to the end of the Term
which shall not be capable of precise determination as aforesaid (and for such
purposes no estimate of any component of the additional rent to accrue pursuant
to the provisions of Section 4 and Section 5 hereof shall be less than the
amount which would be due if each such component continued at the highest
monthly rate or amount in effect during the twelve (12) months immediately
preceding the default), discounted to present value based upon a then
commercially reasonable discount rate.

            (c) In any case in which this Lease shall have been terminated, or
in any case in which Landlord shall have elected to recover the Accelerated Rent
Component and any portion of such sum shall remain unpaid, Landlord may without
further notice, enter upon and repossess the Demised Premises by any lawful
means, and may dispossess Tenant and remove Tenant and all other persons and
property from the Demised Premises and may have, hold and enjoy the Demised
Premises and the rents and profits therefrom. Landlord may, either in its own
name or as agent for Tenant, if this Lease has not been terminated, or in its
own behalf, if this Lease has been terminated, relet the Demised Premises or any
part thereof for such term or terms (which may be greater or less than the
period which would otherwise have constituted the balance of the Term) and on
such terms (which may include concessions of free

                                       17
<PAGE>

rent) as Landlord in its sole discretion may determine. Landlord may, in
connection with any such reletting, cause the Demised Premises to be decorated,
altered, divided, consolidated with other space or otherwise changed or prepared
for reletting. No reletting shall be deemed a surrender and acceptance of the
Demised Premises.

            (d) In the event Landlord shall, after default or breach by Tenant,
recover the Accelerated Rent Component from Tenant and it shall be determined at
the expiration of the Term of this Lease (taken without regard to early
termination for default) that a credit is due Tenant because the net proceeds of
reletting, as aforesaid, plus amounts paid to Landlord by Tenant exceed the
aggregate of rent and other charges accrued in favor of Landlord to the end of
the Term of this Lease, Landlord shall refund such excess to Tenant, without
interest, promptly after such determination.

            (e) In the event that Landlord shall, after default or breach by
Tenant, recover the Accelerated Rent Component and/or retake possession of the
Demised Premises and/or terminate this Lease, then Landlord agrees to use
reasonable efforts to relet the Demised Premises; provided, however, in no event
shall Landlord be required to (i) lease the Demised Premises over other
available space in the Building, (ii) accept a below-market rental rate for the
Demised Premises, (iii) accept any tenant whose creditworthiness is
unsatisfactory to Landlord, in its sole discretion, or (iv) accept any tenant
whose business is not compatible with the other tenants of the Building, as
determined by Landlord in its sole discretion.

            (f) As an alternative remedy of Landlord in the event of termination
of this Lease by Landlord following any breach or default by Tenant, Landlord,
at its option, shall be entitled to recover damages for such breach in an amount
equal to the Accelerated Rent Component (determined from and after the date of
Landlord's election under this subsection (f)) less the fair rental value of the
Demised Premises for the remainder of the term of this Lease (taken without
regard to the early termination) and such damages shall be payable by Tenant
upon demand. Nothing contained in this Lease shall limit or prejudice the right
of Landlord to prove and obtain as damages incident to a termination of this
Lease, in any bankruptcy reorganization or other court proceedings, the maximum
amount allowed by any statute or rule of law in effect with such damages are to
be proved.

            (g) AFTER A DEFAULT OR THE EXPIRATION OF THE TERM, FOR THE PURPOSE
OF OBTAINING POSSESSION OF THE DEMISED PREMISES, TENANT HEREBY AUTHORIZES AND
EMPOWERS THE PROTHONOTARY OR ANY ATTORNEY OF ANY COURT OF RECORD IN THE
COMMONWEALTH OF PENNSYLVANIA OR ELSEWHERE, AS ATTORNEY FOR TENANT AND ALL
PERSONS CLAIMING UNDER OR THROUGH TENANT, TO APPEAR FOR AND CONFESS JUDGMENT
AGAINST TENANT FOR POSSESSION OF THE DEMISED PREMISES, AND AGAINST ALL PERSONS
CLAIMING UNDER OR THROUGH TENANT, IN FAVOR OF LANDLORD, FOR RECOVERY BY LANDLORD
OF POSSESSION THEREOF, FOR WHICH THIS AGREEMENT OR A COPY HEREOF VERIFIED BY
AFFIDAVIT, SHALL BE A SUFFICIENT WARRANT; AND THEREUPON A WRIT OF POSSESSION MAY
IMMEDIATELY ISSUE FOR POSSESSION OF THE DEMISED PREMISES, WITHOUT ANY PRIOR WRIT
OR PROCEEDING WHATSOEVER AND WITHOUT ANY STAY OF EXECUTION. IF FOR ANY REASON
AFTER SUCH ACTION HAS BEEN COMMENCED THE SAME SHALL BE TERMINATED AND THE
POSSESSION OF THE DEMISED PREMISES REMAINS IN OR IS RESTORED TO TENANT, LANDLORD
SHALL HAVE THE RIGHT UPON ANY SUBSEQUENT DEFAULT TO CONFESS JUDGMENT IN ONE OR
MORE FURTHER ACTIONS IN THE MANNER AND FORM SET FORTH ABOVE TO RECOVER
POSSESSION OF SAID DEMISED PREMISES FOR SUCH SUBSEQUENT

                                       18
<PAGE>

DEFAULT. TENANT WAIVES ALL ERRORS IN CONNECTION WITH ANY SUCH CONFESSION OF
JUDGMENT. NO SUCH TERMINATION OF THIS LEASE, NOR TAKING, NOR RECOVERING
POSSESSION OF THE DEMISED PREMISES SHALL DEPRIVE LANDLORD OF ANY REMEDIES OR
ACTION AGAINST TENANT FOR RENT OR FOR DAMAGES DUE OR TO BECOME DUE FOR THE
BREACH OF ANY CONDITION OR COVENANT HEREIN CONTAINED, NOR SHALL THE BRINGING OF
ANY SUCH ACTION FOR RENT, OR BREACH OF COVENANT OR CONDITION NOR THE RESORT TO
ANY OTHER REMEDY HEREIN PROVIDED FOR THE RECOVERY OF RENT OR DAMAGES FOR SUCH
BREACH BE CONSTRUED AS A WAIVER OF THE RIGHT TO INSIST UPON THE FORFEITURE AND
TO OBTAIN POSSESSION IN THE MANNER HEREIN PROVIDED.

            (h) [intentionally omitted]

            (i) Tenant hereby waives all errors and defects of a procedural
nature in any proceedings brought against it by Landlord under this Lease.
Tenant further waives the right to any notices to quit as may be specified by
applicable law, and agrees that five business (5) days notice shall be
sufficient in any case where a longer period may be statutorily specified.

            (j) If rent or any other sum due from Tenant to Landlord shall be
overdue for more than five business (5) days after written notice from Landlord,
it shall thereafter bear interest until paid at the rate of the lesser of (x)
seven percent (7%) above the then prime rate published in the Wall Street
Journal or (y) the highest legal rate.

            (k) Landlord shall be deemed to be in default of this Lease if
Landlord fails to make any payments to Tenant required under this Lease and such
failure continues for ten (10) business days after written notice from Tenant to
Landlord, or if Landlord shall be in default in the prompt and full performance
of any other of its material promises, covenants or agreements contained in this
Lease and such default in performance continues for more than thirty (30) days
after written notice thereof from Tenant to Landlord specifying the particulars
of such default or breach of performance; provide, however, that if the default
complained of, other than for the payment of monies, is of such a nature that
the same cannot reasonably be rectified or cured within such thirty (30) day
period, then such default shall be deemed to be rectified or cured if Landlord,
within such thirty (30) day period, shall have commenced such cure and shall
continue thereafter with due diligence to cause such cure to be completed. Upon
any default of this Lease by Landlord, Tenant shall be entitled to pursue any
and all remedies available to Tenant at law or in equity.

      18. LANDLORD'S RIGHT TO CURE. Landlord may (but shall not be obligated),
on five (5) business days notice to Tenant (except that no notice need be given
in case of emergency) cure on behalf of Tenant any default hereunder by Tenant,
and the cost of such cure (including any attorney's fees incurred) shall be
deemed additional rent payable upon demand.

      19. INSURANCE. (a) Tenant shall at all times during the Term, including
any renewal or extension thereof, maintain in full force and effect with respect

Demised Premises for the full replacement value of such personal property and
leasehold improvements. All liability insurance policies shall name Landlord and
at Landlord's request any mortgagee of all or any portion of the Property as
additional insureds. Tenant shall lodge with Landlord duplicate originals or
certificates of such insurance at or prior to the Commencement Date, together
with evidence of paid-up premiums, and shall lodge with Landlord renewals
thereof at least fifteen (15) days prior to expiration. All such policies or
certificates shall provide that such insurance coverage may not be cancelled or
materially amended unless Landlord and any mortgagee designated by Landlord as

property casualty insurance for the Building in the amount of the replacement
cost thereof, with commercially reasonable deductible amounts.

      20. WAIVER OF SUBROGATION. Each party hereto hereby waives any and every
claim which arises or which may arise in its favor against the other party
hereto during the Term, including any extension or renewal thereof, for any and
all loss of, or damage to, any of its property located within or upon or
constituting a part of the Building, to the extent that such loss or damage is
covered under an insurance policy or policies and to the extent such policy or
policies contain provisions permitting such waivers of claims. Each party agrees
to request its insurers to issue policies containing such provisions and if any
extra premium is payable therefor, the party which would benefit from the
provision shall have the option to pay such additional premium in order to
obtain such benefit.

      21. LIABILITY. (a) Tenant agrees that Landlord, the Property Manager and
their respective officers, employees and agents shall not be liable to Tenant,
and Tenant hereby releases said parties, for any personal injury or damage to or
loss of personal property in the Demised Premises from any cause whatsoever
unless such damage, loss or injury is the result of the negligence or willful
misconduct of Landlord, its Property Manager, or their officers, employees or
agents. Landlord, the Property Manager and their respective officers, employees
and agents shall not be liable to Tenant for any such damage or loss whether or
not the result of their negligence or willful misconduct to the extent Tenant
would be covered by insurance that Tenant is required to carry hereunder. Tenant
shall and does hereby indemnify and hold Landlord harmless of and from all loss
or liability incurred by Landlord (including, without limitation, reasonable
attorney's fees) in connection with any failure of Tenant to fully perform its
obligations under this Lease and in connection with any personal injury or
damage of any type or nature occurring in, or resulting out of Tenant's use of,
the Demised Premises, unless due to the negligence or willful misconduct of
Landlord, its Property Manager, or their officers, employees or agents.

            (b) Landlord shall and does hereby indemnify and hold Tenant
harmless of and from all loss or liability incurred by Tenant (including,
without limitation, reasonable attorney's fees) in connection with any failure
of Landlord to fully perform its obligations under this Lease and in connection
with any personal injury or damage of any type or nature to the extent occurring
in, or resulting out of the negligence or willful misconduct of Landlord, its
Property Manager, or their officers, employees or agents.

      22. ENVIRONMENTAL MATTERS.

            (a) Tenant shall conduct, and cause to be conducted, all operations
and activity at the Demised Premises in compliance with, and shall in all other
respects applicable to the Demised Premises comply with, all applicable present
and future federal, state, municipal and other governmental statutes,
ordinances, regulations, orders, directives and other requirements, and all
present and future requirements of common law, concerning the environment
(hereinafter collectively called "Environmental Statutes") including, without
limitation, (i) those relating to the generation, use, handling, treatment,

handling of hazardous substances, hazardous wastes or hazardous materials (as
such terms are now or hereafter defined under any Environmental Statute) or any
other material, substance, liquid, effluent or product now or hereafter
regulated by any Environmental Statute (all of the foregoing herein collectively
called "Hazardous Substances"), except that construction materials (other than
asbestos or polychlorinated biphenyls), office equipment, fuel and similar
products (if contained in vehicles) and cleaning solutions, and other
maintenance materials that are or contain Hazardous Substances may be used,
generated, handled or stored on the Demised Premises, provided such is incident
to and reasonably necessary for the operation and maintenance of the Demised
Premises as an office and is in compliance with all Environmental Statutes and
all other applicable governmental requirements. Should Tenant, its agents,
employees or invitees cause any release of Hazardous Substances at the Demised
Premises, Tenant shall immediately contain, remove and dispose of, such
Hazardous Substances and any material that was contaminated by the release and
to remedy and mitigate all threats to human health or the environment relating
to such release. When conducting any such measures the Tenant shall comply with
all Environmental Statutes.

            (c) Tenant hereby agrees to indemnify and to hold harmless Landlord
of, from and against any and all expense, loss or liability suffered by Landlord
by reason of Tenant's breach of any of the provisions of this Section,
including, but not limited to, (i) any and all expenses that Landlord may incur
in complying with any Environmental Statutes, (ii) any and all costs that
Landlord may incur in studying, assessing, containing, removing, remedying,
mitigating, or otherwise responding to, the release of any Hazardous Substance
or waste at or from the Demised Premises, (iii) any and all costs for which
Landlord may be liable to any governmental agency for studying, assessing,
containing, removing, remedying, mitigating, or otherwise responding to, the
release of a Hazardous Substance or waste at or from the Demised Premises, (iv)
any and all fines or penalties assessed, or threatened to be assessed, upon
Landlord by reason of a failure of Tenant to comply with any obligations,
covenants or conditions set forth in this Article, and (v) any and all legal
fees and costs incurred by Landlord in connection with any of the foregoing.

            (d) Tenant's covenants, obligations and liabilities under this
Section shall survive the expiration or earlier termination of this Lease.

      23. SUBORDINATION, NONDISTURBANCE AND ATTORNMENT. This Lease is and shall
be subject and subordinate to all the terms and conditions of all underlying
mortgages and to all ground or underlying leases of the entire Building which
may now or hereafter encumber the Building and/or the Property, and to all
renewals, modifications, consolidations, replacements and extensions thereof,
provided, however, that with respect to future mortgages, this Lease shall be
subject and subordinate so long as the holder of any such mortgage shall have
provided to Tenant a nondisturbance agreement which shall provide, inter alia,
that (a) Tenant's rights under this Lease shall not be extinguished by any
foreclosure or other enforcement proceedings so long as Tenant is not in default
under this Lease (b) subject to the foregoing, the Tenant's rights under this
Lease are subordinate to the rights of the holder of such mortgagee, and (c)
Tenant shall attorn to the holder of such mortgage. Except as provided above,
this clause shall be self-operative and no further instrument of subordination
shall be necessary. Notwithstanding the automatic subordination of this Lease,
Tenant shall execute, within five (5) days after request, any certificate that
Landlord may reasonably require acknowledging such subordination. If Landlord
has attached to this Lease, or subsequently delivers to Tenant, a form of
subordination agreement required by a mortgagee of the Property, Tenant shall
execute and return the same to Landlord within five (5) days after receipt
thereof by Tenant. Notwithstanding the foregoing, the party holding the
instrument to which this Lease is subordinate shall have the right to recognize
and preserve this Lease in the event of any foreclosure sale or possessory
action, and in such case this Lease shall continue in full force and effect at
the option of the party holding the superior lien, and Tenant shall attorn to
such party and shall execute, acknowledge and deliver any instrument that has
for its purpose and effect the confirmation of such attornment. Landlord agrees
to use reasonable efforts to obtain a non-disturbance agreement from the
existing mortgagee of the Property (using such mortgagee's standard form
nondisturbance agreement) for the benefit of Tenant.

      24. ESTOPPEL STATEMENT. Tenant shall from time to time, within ten (10)
days after request by Landlord, execute, acknowledge and deliver to Landlord a
statement certifying that this Lease is unmodified and in full force and effect
(or that the same is in full force and effect as modified, listing any
instruments or modifications), the dates to which rent and other charges have
been paid, and whether or not, to the best of Tenant's knowledge, Landlord is in
default or whether Tenant has any claims or demands against Landlord (and, if
so, the default, claim and/or demand shall be specified), and any other
information reasonably requested by Landlord.

      25. INTENTIONALLY OMITTED.

      26. HOLDING-OVER. Should Tenant continue to occupy the Demised Premises
after the expiration of the Term, including any renewal or renewals thereof, or
after a forfeiture incurred, such tenancy shall (without limitation of any of
Landlord's rights or remedies therefor) be one at sufferance at a minimum
monthly rental equal to one hundred fifty percent (150%) of the rent payable for
the last month of the Term.

      27. SECURITY INTEREST. Landlord shall have and Tenant hereby grants to
Landlord, without warranty of any kind, a continuing security interest for all
rentals and other sums of money becoming due hereunder from Tenant, upon all
goods, wares, equipment, fixtures, furniture and inventory and other personal
property of Tenant situate in the Demised Premises. Notwithstanding the
foregoing, Landlord agrees from time to time to execute and deliver a waiver of
such security interest in favor of any reputable lender providing Tenant with
working business credit, provided such waiver is in form reasonably acceptable
to Landlord.

                                       22
<PAGE>

      28. FINANCIAL STATEMENTS. Upon the request of any mortgagee, prospective
mortgagee or prospective purchaser of the Property, Tenant shall provide to
Landlord complete copies of Tenant's latest annual financial statements and such
other information as may be reasonably requested by such mortgagee and/or
purchaser, provided that such party receiving such information agreement agrees
in writing to keep confidential any such information provided by Tenant.

      29. RENT TAX. If, during the Term, including any renewal or extension
thereof, any tax is imposed upon the privilege of renting or occupying the
Demised Premises or upon the amount of rentals collected therefor, Tenant will
pay each month, as additional rent, a sum equal to such tax or charge that is
imposed for such month, but nothing herein shall be taken to require Tenant to
pay any income, estate, inheritance or franchise tax imposed upon Landlord.

      30. QUIET ENJOYMENT. Tenant, upon paying the rent, and observing and
keeping all covenants, agreements and conditions of this Lease on its part to be
kept, shall quietly have and enjoy the Demised Premises during the term of this
Lease without hindrance or molestation by anyone claiming by or through
Landlord, subject, however, to the exceptions, reservations and conditions of
this Lease.

      31. NOTICES. All notices required to be given by Landlord to Tenant shall
be sufficiently given by overnight express delivery service or by courier
service delivery against written receipt or signed proof of delivery, or mailing
the same by registered or certified mail, return receipt requested, to Tenant's
Notice Address. Notices given by Tenant to Landlord must be given by registered
or certified mail, return receipt requested, overnight express delivery service
or by courier service delivery against written receipt or signed proof of
delivery, to Landlord at Landlord's Notice Address, with a copy to the Property
Manager, and to such other person and address as Landlord may from time to time
designate in writing

      32. MISCELLANEOUS.

            (a) Landlord and Tenant each represents and warrants to the other
that it has dealt with no broker, agent or other intermediary in connection with
this Lease other than Landlord's Broker and Tenant's Broker, described in
Section 13 of the Fundamental Lease Provisions, and that insofar as is known, no
other broker, agent or other intermediary negotiated this Lease or introduced
one party to the other or brought the Building to Tenant's attention for the
lease of space therein. Each of Landlord and Tenant agrees to indemnify, defend
and hold harmless the other and the other's partners, employees, agents, their
officers and partners, from and against any claims made by any broker, agent or
other intermediary other than Landlord's Broker or Tenant's Broker, with respect
to a claim for broker's commission or fee or similar compensation brought by any
person in connection with this Lease and claiming through the indemnifying
party. Landlord agrees to pay all commissions payable to Landlord's Broker
pursuant to a separate agreement between Landlord and Landlord's Broker.
Landlord's Broker shall pay Tenant's Broker a co-brokerage commission pursuant
to a separate agreement between Landlord's Broker and Tenant's Broker.

            (b) The word "Tenant" as used in this Lease shall be construed to
mean tenants in all cases where there is more than one tenant, and the necessary
grammatical changes required to make the provisions hereof apply to
corporations, partnerships or individuals, men or women, shall in all cases be
assumed as though in each case fully expressed. This Lease shall not inure to
the benefit of any assignee, heir, legal representative, transferee or successor
of Tenant except in accordance with the provisions of Section 13 of this

                                       23
<PAGE>

Lease. Subject to the foregoing limitation, each provision hereof shall extend
to and shall, as the case may require, bind and inure to the benefit of Tenant
and its respective heirs, legal representatives, successors and assigns.

            (c) The term "Landlord" as used in this Lease means the fee owner of
the Building or, if different, the party holding and exercising the right, as
against all others (except space tenants of the Building) to possession of the
entire Building. In the event of the voluntary transfer of such ownership or
right to a successor-in-interest of Landlord, Landlord shall be freed and
relieved of all liability and obligation hereunder which shall thereafter accrue
(and, as to any unapplied portion of Tenant's security deposit, Landlord shall
be relieved of all liability therefor upon transfer of such portion to its
successor in interest) and Tenant shall look solely to such successor in
interest for the performance of the covenants and obligations of the Landlord
hereunder (either in terms of ownership or possessory rights) from and after the
date of such transfer. The successor in interest shall not (i) be liable for any
previous act or omission of a prior landlord; (ii) be subject to any rental
offsets or defenses against a prior landlord; or (iii) be liable for any
security not actually received by it. Subject to the foregoing, the provisions
hereof shall be binding upon and inure to the benefit of the successors and
assigns of Landlord.

            (d) Notwithstanding anything to the contrary contained in this
Lease, it is expressly understood and agreed by Tenant that none of Landlord's
covenants, undertakings or agreements are made or intended as personal
covenants, undertakings or agreements by Landlord or its partners, shareholders
or trustees, or any of their respective partners, shareholders or trustees, and
any liability for damage or breach or nonperformance by Landlord, or for
Landlord's negligence, shall be collectible only out of Landlord's interest in
the Building and no personal liability is assumed by, nor at any time may be
asserted against, Landlord or its partners, shareholders or trustees or any of
its or their partners, shareholders, trustees, officers, agents, employees,
legal representatives, successors or assigns, if any; all such liability, if
any, being expressly waived and released by Tenant. Notwithstanding anything to
the contrary contained in this Lease, in no event shall Landlord be liable to
Tenant for any consequential damages, lost profits, loss of business or other
similar damages, regardless of whether the same arises out of the negligence of
Landlord, its agents or employees.

            (e) Landlord and Landlord's agents have made no representation,
agreements, conditions, warranties, understandings, or promises, either oral or
written, other than as herein set forth, with respect to this Lease, the
Building, the Property, the Demised Premises, or otherwise.

            (f) Time is of the essence of this Lease and all of its provisions

            (g) If a party is delayed or prevented from performing any of its
obligations under this Lease by reason of causes beyond its control, the period
of such delay or prevention shall be deemed added to the time herein provided
for the performance of any such obligation by such party, provided, however,
that the foregoing shall not under any circumstances excuse Tenant from the
timely payment of rent hereunder.

            (h) Landlord represents and warrants to Tenant that, to Landlord's
actual knowledge, at the time of delivery of the Demised Premises, the Building
and the Demised Premises shall be in compliance with all applicable municipal,
state and federal laws, rules and regulations, including without limitation the
Americans with Disabilities Act and all applicable building, zoning,
environmental, fire, health and safety codes. Landlord represents that to
Landlord's actual knowledge, neither on the date hereof nor on the Commencement
Date shall

                                       24
<PAGE>

there be any Hazardous Materials within or under the Demised Premises, the
Building or the Property in violation of any Environmental Law.

            (i) Tenant shall not record this Lease or any memorandum thereof.

      33. PRIOR AGREEMENT, AMENDMENTS. This Lease, the exhibits, and any riders
attached hereto and forming a part hereof set forth all of the promises,
agreements, conditions, warranties, representations and understandings between
Landlord and Tenant relative to the Premises and this leasehold. No alteration,
amendment, modification, waiver, understanding or addition to this Lease shall
be binding upon Landlord unless reduced to writing and signed by Landlord or by
a duly authorized agent of Landlord empowered by a written authority signed by
Landlord.

      34. CAPTIONS. The captions of the paragraphs in this Lease are inserted
and included solely for convenience and shall not be considered or given any
effect in construing the provisions hereof.

      35. SEVERABILITY. If any provision contained in this Lease shall, to any
extent, be invalid or unenforceable the remainder of this Lease (and the
application of such provision to the persons or circumstances, if any, other
than those as to which it is invalid or unenforceable) shall not be affected
thereby, and each and every provision of this Lease shall be valid and
enforceable to the fullest extent permitted by law.

      36. GOVERNING LAW. This Lease shall be governed by and construed in
accordance with the laws of the State in which the Property is located.

      37. DELIVERY FOR EXAMINATION. DELIVERY OF THE LEASE TO TENANT SHALL NOT
BIND LANDLORD IN ANY MANNER, AND NO LEASE OR OBLIGATIONS OF LANDLORD SHALL ARISE
UNTIL THIS INSTRUMENT IS SIGNED BY BOTH LANDLORD AND TENANT.
