         8.1      Prepayment by the Borrower. The Borrower may prepay the Notes
in whole or in part at any time after the Purchaser has exercised a purchase
right under Section 3.2 of the Exchange Agreement; otherwise, the Notes may not

stock having a Fair Value equal to the amount of interest latest then owed. In
the event the Borrower elects to make payment by transfer of additional shares,
they shall be delivered to the Purchaser free and clear of all Liens, and

                  (b) If the Borrower, iXL or the Parent (the guarantor under
the Guaranty) shall make a general assignment for the benefit of creditors; or

in such proceeding, or shall seek or consent to or acquiesce in the appointment
of any trustee, receiver or liquidator of the Borrower, iXL or the Parent of all
or any substantial part of the properties of the Borrower, iXL or the Parent, or
the Borrower, iXL or the Parent shall commence the winding up or the dissolution
or liquidation of such person or the assets of such person; or

                  (d) If the Guaranty ceases to be in full force and effect for
any reason or the Parent asserts at any time that the Guaranty is unenforceable
or not in full force or effect; or

                  (e) If an event shall occur or any condition shall exist in
respect of any indebtedness for borrowed money of iXL or the Parent, or under
any agreement securing or relating to such indebtedness:

                           (A) as a result of which the holder or holders of
                           such indebtedness, or some group of such holders or a
                           trustee or agent acting on their behalf, accelerates
                           the maturity of such indebtedness, or a portion
                           thereof, or

                           (B) that results in any one or more of the holders
                           thereof or a trustee therefor requiring iXL or the
                           Parent pursuant to a then existing contractual right
                           to repurchase such indebtedness from the holders
                           thereof;

                  provided, that the aggregate amount of all obligations in
respect of all such indebtedness for borrowed money under this subsection (e)
exceeds at such time one million dollars ($1,000,000); or

                  (f) If the representations and warranties of the Borrower or
the Parent in this Agreement, in the Notes, in the Guaranty or in any other Loan
Documents are not true and correct as of the date that they are made and cease

                  then, and in each and every such case, the Purchaser may by 3
(three) days advance notice in writing to the Borrower declare all amounts under
the Notes to be forthwith due and payable (except that, in the case of an Event
of Default under Section 9.1(c), the Notes shall become immediately due and
payable without notice) and thereupon the balance shall become so due and
payable, without presentation, protest or further demand or notice of any kind,
all of which are hereby expressly waived. If an Event of Default occurs with
respect to the Notes, then the unpaid principal amount of the Notes shall bear
interest from and including the Maturity Date (as defined in the Notes) to and
including the date of payment at an annual rate equal to the Overdue Rate (as
defined in the Notes).

call rights as described under Section 10.2 below with respect to an aggregate
of 10,000,000 shares of common stock, $0.01 par value per share, of the
Purchaser, owned by the Parent (the "Call Shares") at a purchase price per share
of $3.00 (such number and call price to be adjusted to reflect any stock splits,
combinations or the like after the date hereof).

         10.2     Exercise. The Purchaser may exercise its call rights at any
time (and from time to time) prior to the close of business on January 7, 2004
by giving the Parent written notice thereof at the Parent's address for notices
set forth in Section 12.6 hereto, such notice to indicate that call rights are
being exercised under this Section 10.2, indicate the number of Call Shares to
be purchased and specify a closing date. The call rights may be exercised for
all or a portion of the Call Shares, provided, however that the minimum amount
of Call Shares purchased at any one time shall be 500,000 Call Shares (such
number to be adjusted for any stock splits, combinations or the like after the
date hereof). With the prior approval of the Purchaser's board of directors, the
Purchaser may designate another person or entity to purchase all or any portion
of the Call Shares, such designation to be set forth in the notice referred to
above; provided, that, for purposes of the foregoing board approval, iXL
Designees (as defined in the Restated Stockholders' Agreement), if any, may
participate in the meeting, if any, and vote on such


                                      -11-

approval by the board of directors.

         10.3     Closing re: Call Shares. The closing for the purchase of the
Call Shares by the Purchaser shall be the date specified in the notice referred
to above, provided that it shall be no earlier than 15 days after, and no later
than 45 days after, delivery of the notice. At the closing, the Parent shall
deliver the certificates representing the number of Call Shares being purchased
by the Purchaser free and clear of all Liens (including without limitation the
Chase Security Interest), and the Purchaser shall pay the call price by wire
transfer to an account designated by the Parent in writing to the Purchaser at
least two business days prior to the closing, or if no such designation is made,
by check.

         10.4     Termination. The call rights under Section 10.2 hereto shall
terminate upon the occurrence of the closing of a Qualified Public Offering (as
defined in the Restated Stockholders' Agreement).

         10.5     Legend. The Purchaser may place a legend on the certificates
representing the Call Shares indicating that the Call Shares are subject to the
call rights provided herein.

         10.6     No Restrictions. Neither the Parent nor the Borrower shall
enter into covenants or agreements which would restrict the ability of the
Parent to transfer the Call Shares in connection with the exercise of call
rights herein.

         10.7     Conditions to Closing. The obligations of the Purchaser to
purchase the Call Shares and the obligations of the Parent to sell the Call
Shares are each conditioned upon release of the Chase Security Interest with
respect to the Call Shares by the secured parties thereof and receipt of the
consent of certain stockholders of the Purchaser as may be required pursuant to
the Certificate of Incorporation of the Purchaser, as amended, and pursuant to
the Stockholders' Agreement (the "Call Consent"). (Prior to the Closing, upon
request by the Purchaser, the Parent shall provide the Purchaser with evidence
in reasonable detail of such release of the Chase Security Interest.)

breach or default under this Agreement, or any waiver on the part of any party
of any provisions or conditions of this Agreement, must be made in writing and

                             iXL Ventures PHC, Inc.

                     5.75% SECURED CONVERTIBLE NOTE DUE 2004

                                                               December 19, 2000
$20,000,000.00


         iXL VENTURES PHC, INC., a Delaware corporation (herein, together with
its successors and assigns, called the "MAKER"), for value received hereby
promises to pay to PROACT TECHNOLOGIES CORP., a Delaware corporation (herein,
together with its successors and assigns, called the "LENDER"), the principal
sum of TWENTY MILLION DOLLARS (US$20,000,000.00), as provided herein, together
with interest (computed, in arrears, on the basis of a 360-day year of twelve
30-day months) (a) on the unpaid balance thereof, at the rate of 5.75% per
annum, compounding quarterly on the last day of each March, June, September and
December for each calendar year (the "INTEREST RATE") from the date hereof to
and including the date paid, and (b) on any due and unpaid payment (including
any due and unpaid required or optional prepayment) of principal, and to the
extent permitted by law, any due and unpaid payment of interest, at the rate of
6.75% per annum compounding quarterly (the "OVERDUE RATE").

         This Note is the Maker's 5.75% Secured Convertible Note due 2004 (the
"NOTE") issued pursuant to the Note Purchase Agreement, dated as of the date
hereof (the "LOAN AGREEMENT"), between the Maker and the Lender and certain
other parties. The Note is guaranteed by iXL Ventures, L.P., a Delaware limited
partnership, as provided by the terms of the Guaranty dated the date hereof
issued by iXL Ventures, L.P. All capitalized terms, and their rules of usage,
used herein without definition shall have the meanings set forth in the Loan
Agreement.

         As used herein, the term "HOLDER" means the Lender and each person (if
any) to which such named Holder sells or otherwise transfers this Note or any
Notes issued in exchange, substitution or replacement herefor in accordance with
the terms of the Loan Agreement.

         SECTION 1.  SECURITY; EXCHANGE AGREEMENT. This Note is secured by
certain shares of common stock of the Lender and proceeds related thereto held
by the Borrower, as provided by


                                      -1-
<PAGE>   23

the terms of the Stock Pledge Agreement dated as of the date hereof between the
Lender and the Borrower (the "PLEDGE AGREEMENT"). Reference is hereby made to
the Loan Agreement and the Pledge Agreement for a description of and the nature
and extent of the security for the Note, and the nature and extent of the pledge
and the rights of Holder and the Maker in respect of the security or otherwise.
This Note is also subject to the terms of the Exchange Agreement dated as of the
date hereof by and between the Lender and the Borrower.

         SECTION 2. PAYMENTS. All payments in respect of this Note will be made
in full when due, upon presentation of this Note at the principle executive
offices of the Lender, by wire transfer of immediately available funds; provided
that pursuant to Article VIII of the Loan Agreement, the Maker may repay (i) the
principal amount owed under this Note by transfer of the Pledged Collateral to
the Lender and (ii) the interest obligations under this Note by transfer of
Shares to the Lender having a Fair Value equal to the amount of interest owed.
In the event that the principal obligations are repaid by transfer of Pledged
Collateral in accordance with the Loan Agreement, interest shall no longer
accrue with respect to the principal. Interest on this Note will accrue
quarterly, on the last day of each March, June, September, and December,
commencing on March 31, 2001. The entire amount of unpaid principal, accrued and
unpaid interest and all other amounts payable under the Loan Documents, if any,
will be due and payable on January 7, 2004 or such earlier date as is provided
for in the Loan Agreement (in either case, the "MATURITY DATE"). Upon full
payment of the entire indebtedness represented by this Note, the Lender will
mark this Note "Paid in Full" and surrender this Note to the Maker for
cancellation.

         SECTION 3.  PREPAYMENT. This Note is subject to prepayment from time to
time only under the circumstances and in compliance with the terms and
conditions set forth in the Loan Agreement.

         SECTION 4. CONVERSION OPTION. This Note can be converted, in whole or
in part, at the option of the holder, into shares of Common Stock, $.01 par
value per share, of the Maker, in the manner, and upon the terms and conditions
provided in the Loan Agreement.

         SECTION 5. ABSOLUTE OBLIGATION. No reference herein to the Loan
Agreement and no provision hereof or thereof shall alter or impair the
obligation of the Maker, which is absolute and unconditional, to pay the
principal hereof and interest hereon at the respective times and places
specified herein and in the Loan Agreement.

         SECTION 6.  ASSIGNMENT. This Note is transferable only upon the terms
and conditions set forth in the Loan Agreement.

         SECTION 7. NON-BUSINESS DAY. If any payment of interest due hereunder
becomes due and payable on a day which is not a Business Day (as defined in the
Loan Agreement), the due date thereof shall be the next preceding day which is a
Business Day, and the interest payable on such next preceding Business Day shall
be the interest which would otherwise have been payable on the due date which
was not a Business Day.

         SECTION 8. DEFAULTS; REMEDIES. Upon the occurrence of an Event of
Default, Holder may exercise any and all of the rights and remedies provided for
under any and all of the Loan Documents or otherwise available at law or in
equity. The Loan Documents provide, among other things, that upon an Event of
Default, Holder may, among other things, accelerate the Maturity Date and in
connection therewith the entire indebtedness represented by this Note will
automatically become due and payable by the Maker. Upon an Event of Default,
Holder individually may, among other things, accelerate the Maturity Date and in
connection therewith the entire Indebtedness represented by this Note will
automatically become due and payable by the Maker. In addition to all other
amounts that may at any time be payable under the Loan Documents, the
undersigned agrees to pay upon demand all expenses of any kind (including,
without limitation, reasonable attorneys' fees and expenses) incurred by the
Lender or Holder in collecting any amount due and unpaid hereunder.

         SECTION 9. COLLECTION COSTS. Should any indebtedness represented by
this Note be collected at law or in equity, or in bankruptcy or other
proceedings, or should this Note be placed in the hands of attorneys for
collection after default, the undersigned agrees to pay, in addition to the
principal and interest due and payable hereon, all costs of collecting or
attempting to collect this Note, including reasonable attorneys' fees and
expenses (including those incurred in connection with any appeal), whether or
not any dispute as to the validity or enforceability of any provision of the
Note or any of the Loan Documents results in litigation and whether or not any
such litigation is prosecuted to judgment, unless judgment is entered for the
Maker in any such enforcement or collection effort in which case the Holder will
pay the reasonable attorneys' fees and expenses of the Maker.

         SECTION 10. SEVERABILITY. If any provision of this Note shall be held
to be invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other provision hereof, and
this Note shall be construed as if such invalid, illegal or unenforceable
provision had never been contained herein.

         SECTION 11. GOVERNING LAW. This Note shall be governed by the laws of
the State of New York, without regard, to the fullest extent permitted by law,
to any conflict of laws which might result in the application of the laws of any
other jurisdiction.

         SECTION 12. JURISDICTION; WAIVER OF JURY TRIAL. The Borrower
irrevocably submits to the non-exclusive jurisdiction of (i) the state courts of
the State of New York, New York County, and (ii) the United States District
Court for the Southern District of New York, for the purposes of any suit,
action or other proceeding arising out of this Note or any transactions
contemplated hereby. The Borrower, for itself and in connection with its
properties, generally and unconditionally, waives any defense of forum non
conveniens, and irrevocably agrees to be bound by any judgment rendered in
connection with this Note.

         Each of the parties hereto hereby waives its respective rights to a
jury trial of any claim or cause of action based upon or arising out of this
Note. The scope of this waiver is intended to


                                      -3-

be all-encompassing of any and all disputes that may be filed in any court and
that relate to the subject matter of this agreement, including without
limitation contract claims, tort claims, breach of duty claims, and all other
common law and statutory claims.

                             STOCK PLEDGE AGREEMENT


         STOCK PLEDGE AGREEMENT (this "Pledge Agreement") dated as of December
19, 2000 by and among iXL Ventures PHC, Inc., a Delaware corporation
("Borrower"), and ProAct Technologies Corp., a Delaware corporation ("Lender").

         WHEREAS, Borrower, iXL Ventures, L.P., iXL Enterprises, Inc. and Lender
have entered into a Note Purchase Agreement dated as of the date hereof ("Loan
Agreement"), pursuant to which Lender has agreed to purchase $20,000,000
principal amount of 5.75% Secured Convertible Notes due 2004 (the "Notes") upon
the terms and subject to the conditions set forth therein;

         WHEREAS, Borrower and Lender have entered into an Exchange Agreement
dated as of the date hereof (the "Exchange Agreement");

         WHEREAS, Borrower will receive substantial benefit from the issuance of
the Notes;

         WHEREAS, Borrower will grant a security interest in certain of its
assets in favor of Lender to secure its obligations under the Exchange Agreement
and the Notes; and

         WHEREAS, it is a condition precedent to the obligation of Lender to
purchase the Notes that Borrower shall have executed and delivered this Pledge
Agreement.

         NOW, THEREFORE, in consideration of the foregoing and in order to
induce Lender to enter into the Loan Agreement and the Exchange Agreement and
for other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, it is agreed as follows:

         Section 1.  Definitions. Capitalized terms used in this Pledge
Agreement without definition shall have the meanings set forth in the Loan
Agreement. The term "Event of Default" refers to an Event of Default as defined
in the Loan Agreement or the Exchange Agreement. When used herein, the term
"including" means "including without limitation."

         Section 2.  Pledge. As collateral security for the prompt performance
by Borrower of its obligations under the Loan Documents (including the Exchange
Agreement), the Guarantor hereby pledges, assigns, hypothecates and transfers to
Lender (x) 10 million shares of the Common Stock of Lender held by Borrower (as
such number of shares may be adjusted for stock splits, recapitalizations, stock
dividends, etc.) (the "Pledged Shares")), and (y) all proceeds (including
dividends) payable in respect of the Pledged Shares ("Proceeds") (together with
the Pledged Shares, the "Pledged Collateral"); and represents and warrants that
such security interest shall, when UCC-1 financing statements have been properly
filed in the appropriate offices, grant a first priority security interest in
the Pledged Collateral in favor of Lender.


<PAGE>   28

         Section 3.  Security for Obligations. This Pledge Agreement shall
secure, and the Pledged Collateral shall be security for, the prompt payment in
full when due, and performance of, all obligations of Borrower to Lender under
the Notes and the other Loan Documents, including the costs of collection
thereof, to Lender or any assignee, indorsee or transferee of Lender and
including, without limitation, all reasonable attorneys fees and all obligations
of Borrower under the Exchange Agreement (the "Secured Obligations"). Upon the
occurrence of any Event of Default, Lender is entitled to take for its own
account, or to dispose of, the Pledged Collateral in accordance with the terms
of this Pledge Agreement.

         Section 4.  Rights of Lender. This Pledge Agreement is intended to
convey to Lender all of Borrower's rights with respect to the Pledged Collateral
(including, subject to Section 7(a)(i), the right to receive monies with respect
to the Pledged Shares) and none of Borrower's duties with respect thereto.
Lender shall not be liable for failure to collect or realize upon the Secured
Obligations or the Pledged Collateral, or any part thereof, or for any delay in
so doing, nor shall Lender be under any obligation to take any action whatsoever
with regard thereto. Upon the failure of Borrower to pay any amounts owed to
Lender in respect of the Secured Obligations, all or any part of the Pledged
Collateral may be registered in the name of Lender and/or a nominee of Lender.
Borrower hereby authorizes Lender to take all actions necessary to effectuate
this Pledge Agreement as their attorney-in-fact and to execute any and all
documents, with or without designation of Lender's signing capacity, on behalf
of Borrower in connection with all activities contemplated by this Pledge
Agreement, including, without limitation, to receive, endorse and collect,
subject to Section 7(a)(i), all instruments made payable to Borrower
representing any payment or other distribution in respect of the Pledged
Collateral or any part thereof and to give full discharge for the same.

         Section 5.  Representations and Warranties of Borrower. Borrower
represents and warrants that:

         (a)      Borrower is the legal record and beneficial owner of, and has
good and marketable title to, the Pledged Collateral, subject to no pledge,
lien, mortgage, hypothecation, security interest, charge, option or other
encumbrance whatsoever;

         (b)      Borrower has full power, authority and legal right to pledge
all the Pledged Collateral pursuant to this Pledge Agreement; and

         (c)      the pledge, assignment, hypothecation, transfer and delivery
of the Pledged Collateral pursuant to this Pledge Agreement creates, when UCC-1
financing statements have been properly filed in the appropriate offices, a
valid first lien on and a fully perfected first priority security interest in
the Pledged Collateral, and the proceeds thereof, subject to no prior pledge,
lien, mortgage, hypothecation, security interest, charge, option or encumbrance
or to any agreement purporting to grant to any third party a security interest
in the Pledged Collateral except as set forth in clause (a) of this Section 5.

         Section 6.  Covenants. Borrower covenants and agrees that until the
Termination Date (as defined in Section 10):


                                      -2-
<PAGE>   29

         (a)      Borrower will not sell, assign, transfer, exchange or
otherwise dispose of, or grant any option with respect to, the Pledged
Collateral, nor will Borrower create, incur or permit to exist any pledge, lien,
mortgage, hypothecation, security interest, charge, option or other encumbrance
with respect to the Pledged Collateral (other than the lien created by this
Pledge Agreement);

         (b)      Borrower will, at its sole expense, promptly execute,
acknowledge and deliver all such instruments and take all such action as Lender
from time to time may reasonably request in order to ensure to Lender the
benefits of the liens in and to the Pledged Collateral intended to be created by
this Pledge Agreement;

         (c)      Borrower will defend the right, title and security interest of
Lender in and to the Pledged Collateral against the claim of any entity or
person and will maintain and preserve such liens until such Pledged Collateral
is released pursuant to Section 10; and

         (d)      Borrower will comply with the provisions set forth in Article

         (b)      Borrower hereby agrees to execute and deliver (or cause to be
executed and delivered) all such instruments as Lender may reasonably request

         Section 8.  Defaults and Remedies.

         (a)      Upon any Event of Default, Lender, in addition to all rights
of Lender created under the other Loan Documents, shall have and may exercise
with respect to the Pledged Collateral, all rights and remedies available to
secured creditors under the New York Commercial Code, or otherwise at law or in
equity including, without limiting the generality of the foregoing, (i) the
right to take the Pledged Collateral (or portion thereof) for its own account as
provided in clause (b) of this Section 8 and (ii) the right to sell or assign
the Pledged Collateral, or any part thereof, at public or private sale in New
York or elsewhere as Lender may determine in good faith to be commercially
reasonable and at such prices as Lender may deem best and commercially
reasonable. The parties agree that written notice mailed to Borrower not less
than ten days prior to any public sale of the Pledged Collateral or ten days
prior to the date after which any private sale or other disposition of such
Pledge Collateral will be made shall constitute reasonable notice (all other
notices, demands or advertisements of any kind being hereby expressly waived),
but notice given in any other reasonable manner or at any other reasonable time
shall be sufficient. At any such sale, Lender shall have the right to purchase
the Pledged Collateral, or any part thereof.

         To the extent Lender is restricted from making sales of Pledged
Collateral without registration under the Securities Act, the following shall
govern:

                  (i)      at any such sale, Lender, at its discretion, may
restrict the potential bidders or purchasers to institutional investors, and/or
other persons who shall represent and warrant that they are acquiring the
Pledged Collateral for their own account, for investment only and not with a
view toward the resale or distribution thereof and which will make such further
representations and warranties as Lender may, in its discretion, deem necessary
or desirable to assure Lender that such prospective bidders or purchasers are,
with respect to applicable federal and state securities laws and rules, suitable
bidders and purchasers of such Pledged Collateral;

                  (ii)     Lender may additionally decide to sell the Pledged
Collateral in one or more private sales or in such other manner and subject to
such restrictions and conditions as Lender, in its discretion, shall deem
necessary in order for such sale to be exempt from the registration requirement
of the Securities Act, and applicable state securities laws; and

                  (iii)    Borrower consents to any sales made in the manner
above-described and agrees that sales made as above-described shall be deemed to
have been made in a commercially reasonable manner and Borrower further agrees
that Lender shall have no obligation to delay sale of any of the Pledged
Collateral for the period of time necessary to permit the offering and sale of
such Collateral to be registered for public sale under the Securities Act, and
applicable state securities laws, and no representation is made that any such
registration is possible or will be made.

         (b)      Upon the occurrence and during the continuation of any Event
of Default, Lender shall have the right, in lieu of selling Pledged Collateral
as provided in clause (a) of this Section 8, to take for its own account a
portion of the Pledged Collateral with an Appraised


                                      -4-
<PAGE>   31

Value (as hereinafter defined) equal to the amount of the Secured Obligations as
to which Borrower shall be in default (the "Foreclosed Collateral") upon ten
(10) days prior written notice (which notice shall state the Appraised Value
ascribed thereto). In such event, Lender shall thereafter have all right, title
and interest in and to such Foreclosed Collateral free of any liens, claims or
encumbrances and Borrower's interest therein shall terminate, as if such
Foreclosed Collateral had been sold to a third party in accordance with the
procedures contemplated by clause (a) of this Section 8. "Appraised Value" shall
mean the fair market value of such Pledged Collateral on the day prior to the
date of the notice provided for herein as determined by a nationally recognized
independent investment banking firm mutually and promptly selected by Lender and
Borrower. Such firm shall make its determination as promptly as possible after
its retention. In the event that Borrower and Lender are unable to agree upon a
mutually acceptable firm within 10 days after notice from Lender to Borrower,
Lender may select a nationally recognized independent investment banking firm to
conduct the appraisal.

         (c)      Any cash held by or on behalf of Lender as Pledged Collateral
and all cash proceeds received by or on behalf of Lender in respect of any sale
of, liquidation of, or other realization upon or all or any part of the Pledged
Collateral shall be applied by Lender as follows:

                  (i)      First, to the payment of the costs and expenses of
such sale or of enforcing Lender's rights under this Pledge Agreement or
the other Loan Documents, including reasonable expenses of Lender's counsel, and
all other of the expenses, liabilities and advances made or incurred by Lender
in connection therewith; and

                  (ii)     Next, to the payment of the Secured Obligations, all
in accordance with the terms and provisions of the Loan Documents; and

                  (iii)    Finally, after payment in full of all of the Secured
Obligations, to Borrower, or its successors or assigns, or to whomsoever may be
lawfully entitled to receive the same or as a court of competent jurisdiction
may direct, of any surplus then remaining from such proceeds.

         Section 9.  Waiver. No delay on the part of Lender in exercising any
power of sale, lien, option or other right hereunder, and no notice or demand
which may be given to or made upon Borrower by Lender with respect to any power
of sale, lien, option or other right hereunder, shall constitute a waiver
thereof, or limit or impair Lender's right to take any action or to exercise any
power of sale, lien, option, or any other right hereunder, or prejudice Lender's
rights as against Borrower in any respect.

         Section 10.  Termination. Upon payment in full of the Secured
Obligations, this Pledge Agreement shall terminate and Lender shall deliver to
Borrower such instruments of assignment or other documents of transfer as shall
be reasonably requested by Borrower and any instruments of assignment or
documents of transfer executed in connection therewith to release the Pledged
Collateral.

         Section 11.  Miscellaneous. This Pledge Agreement shall be binding upon
Borrower and their respective successors and assigns, and shall inure to the
benefit of, and be enforceable by, Lender and its successors and assigns, and
none of the terms or provisions of this Pledge Agreement may be waived, altered,
modified or amended except in writing duly signed by Lender and Borrower.

         Section 12.  Severability. If for any reason any provision or
provisions hereof are determined to be invalid and contrary to any existing or

<PAGE>   35

                                    GUARANTY

         GUARANTY (the "Guaranty") dated as of December 19, 2000 by iXL
VENTURES, L.P., a Delaware limited partnership (the "Guarantor"), in favor of
PROACT TECHNOLOGIES CORP., a Delaware corporation (the "Lender").

         WHEREAS, iXL Ventures PHC, Inc., a Delaware corporation ("Borrower"),
is a party to a Note Purchase Agreement dated as of the date hereof by and among
the Borrower, iXL Enterprises, Inc., the Guarantor and the Lender (the "Loan
Agreement");

         WHEREAS, the Loan Agreement provides for a loan of $20 million to be
made by the Lender to the Borrower, secured by a first priority security
interest in 10 million shares of common stock, $.01 par value per share, of the
Lender held by the Borrower to be pledged (together with proceeds thereof) to
the Lender pursuant to the terms of a Stock Pledge Agreement dated as of the
date hereof (the "Pledge Agreement") (the "Pledged Shares");

         WHEREAS, the Borrower has issued $20 million of 5.75% Secured
Convertible Notes due 2004 (the "Notes") in favor of the Lender, pursuant to the
terms of the Loan Agreement;

         WHEREAS, the Borrower has agreed to the terms of an Exchange Agreement
dated as of the date hereof between the Borrower and the Lender, providing for
mutual exchange rights permitting the parties, under conditions specified
therein, to exchange the Notes for the Pledged Shares (the "Exchange
Agreement");

         WHEREAS, the Lender has requested the Guarantor to provide a limited
recourse guaranty to the Lender of the Borrower's obligations to repay the Notes
plus interest thereon and other Guaranty Obligations (defined below) pursuant to
the Agreement on the terms and conditions hereinafter provided, such guaranty to
be secured by a pledge of the capital stock of the Borrower pursuant to the
terms of the Parent Pledge Agreement (defined below);

         WHEREAS, Guarantor is willing to enter into this Guaranty to induce the
Lender to purchase the Notes under the Loan Agreement;

         NOW, THEREFORE, Guarantor hereby agrees:

         SECTION 1.  GUARANTY.

         1.1      Guaranty. From after the date hereof, Guarantor hereby
irrevocably and unconditionally guarantees (x) the due and punctual payment by
the Borrower of the Notes and interest thereon, on January 7, 2004 or such
sooner date as the same shall become due and payable, whether at maturity, or
otherwise under the Loan Agreement and (y) the due and punctual performance of
the Borrower's obligations under the Loan Agreement, the Notes, the Exchange
Agreement and the Pledge Agreement (collectively, the "Loan Documents") (such
obligations, the "Guaranty Obligations"). Except as set forth in Section 1.1,
Guarantor agrees


<PAGE>   36

that its Guaranty Obligations hereunder shall be absolute, present, continuing
and unconditional, irrespective of the validity, regularity or enforceability of
the Loan Agreement, or the other Loan Documents, the absence of any action to
enforce the same, any waiver or consent by the Lender with respect to any
provision thereof, the recovery of any judgment against the Borrower or any
action to enforce the same, or any other circumstances which may otherwise
constitute a legal or equitable discharge or defense of a guarantor (except as
provided in Section 1.2 below). The term "Interest Obligations" means the
obligations of the Borrower to pay interest under the Notes; provided that (x)
if the principal amount of the Notes is repaid by transfer of Purchaser Shares
as provided under the terms of the Note Purchase Agreement, or (y) if the
Company has completely foreclosed upon the Pledged Collateral under the Pledge
Agreement or (z) an Event of Default has occurred, the Company has a right to
foreclose on the Pledged Collateral, there is no stay in effect preventing such
foreclosure, and the Company fails to take reasonable steps to effectuate a
foreclosure with respect to all of the Pledged Collateral (any such event in
clauses (x), (y) or (z), a "Cut-Off Event"), then, in each case, for purposes of
this Agreement, from and after a Cut-Off Event, Interest Obligations shall no
longer accrue with respect to the principal amount of the Notes (but interest
may continue to accrue with respect to unpaid interest).

         1.2      Defenses, etc. Notwithstanding any provision of this Guaranty,
Guarantor shall have the same defenses, set-offs and claims, if any, with
respect to the enforcement against Guarantor of any Guaranty Obligations as
would the Borrower with respect to such Guaranty Obligations (except for any
defenses based upon or arising out of or in connection with the Borrower's
voluntary or involuntary bankruptcy, assignment for the benefit of creditors,
reorganization or similar proceedings affecting the Borrower or any of its
assets).

         1.3      Subrogation. Guarantor shall be subrogated to all rights of
the Lender in respect of any amounts paid by (or performance by) Guarantor
pursuant to the provisions of this Guaranty; provided, however, that Guarantor
shall be entitled to enforce, or to receive any payments arising out of or based
upon, such right of subrogation with respect to any claim only after all amounts
owed by (or performance by) Guarantor and the Borrower to the Lender in respect
of the Lender, the Loan Agreement and other Loan Documents have been paid in
full (or performed in full).

         1.4      Guaranty of Payment. The Guarantor further agrees that its
guaranty constitutes a guaranty of payment when due and not of collection, and
waives any right to require that any resort be had by the Lender to any of the
security held for payment of the Guaranty Obligations or to any balance of any
deposit account or credit on the books of the Lender in favor of the Borrower or
any other person.

         SECTION 2.  LIMITED RECOURSE TO THE GUARANTOR.

         Anything contained herein to the contrary notwithstanding, no recourse
shall be had for the payment of the principal of or other amounts due on the
Notes or for any claim based


                                      -2-
<PAGE>   37

thereon or otherwise in respect thereof or for the payment and performance of
any other obligation based on or in respect of any Loan Document (in each case
other than the Interest Obligations) against (i) the Guarantor, or (ii) any
officer, director or partner of the Guarantor and the enforcement of any
judgment for breach by the Guarantor of its obligations hereunder shall be made
only against the Collateral; provided, that with respect to the Interest
Obligations this Guaranty shall be a full recourse guaranty. The foregoing
provisions shall not (a) prevent recourse against the Borrower or with respect
to the collateral pledged pursuant to the Pledge Agreement or the Collateral
pledged pursuant to the Parent Pledge Agreement or constitute a waiver, release
or discharge of any indebtedness or obligation evidenced by the Note or any Loan
Document or secured by any Loan Document, and the same shall continue until paid
or discharged, (b) limit the right of any person to name the Guarantor or its
successor or assign as a party defendant in any action or suit for judicial
foreclosure of or in the exercise of any other remedy under the Note or under
any Loan Document, so long as no monetary judgment or judgment seeking personal
liability, the expenditure of money or the performance of any act requiring the
expenditure of money shall be sought against the Guarantor or any successor or
assign of such Guarantor, except with respect to the Interest Obligations (as to
which there is full recourse) or (c) limit or impair, in any manner, any right,
remedy or recourse Lender may have against the Guarantor for actual fraud,
willful diversion or misapplication of any portion of the Collateral by the
Guarantor or the Borrower.

         SECTION 3.  SECURITY.

         The Guarantor authorizes the Lenders to take and hold security for the
payment of the Guaranty Obligations and exchange, enforce, waive and release any
such security, and apply such security and direct the order or manner of sale
thereof as the Lender in its sole discretion may determine in accordance with
the terms of the Parent Pledge Agreement dated as of the date hereof, by and
between the Guarantor and the Lender (the "Parent Pledge Agreement"). The term
"Collateral" has the meaning provided in the Parent Pledge Agreement.

         SECTION 4.  MISCELLANEOUS.

         Section 4.1.  Notices. All notices to Guarantor under this Guaranty and
copies of all notices to the Borrower under the Agreement shall, until Guarantor
furnishes written notice to the contrary, be in writing and mailed, faxed or
delivered to Guarantor at [address].

         Section 4.2.  Governing Law. This Guaranty shall be construed and
enforced in accordance with, and governed by, the laws of the State of New York,
without regard, to the fullest extent permitted by law, to any conflict of laws
rules which might apply the laws of any other jurisdiction.

         Section 4.3.  Jurisdiction; Waiver of Jury Trial. (a) The Guarantor
irrevocably submits to the non-exclusive jurisdiction of (i) the state courts of
the State of New York, New


                                      -3-
<PAGE>   38
York County, and (ii) the United States District Court for the Southern District
of New York, for the purposes of any suit, action or other proceeding arising
out of this Note or any transactions contemplated hereby. The Guarantor, for
itself and in connection with its properties, generally and unconditionally,
waives any defense of forum non conveniens, and irrevocably agrees to be bound
by any judgment rendered in connection with this Guaranty.

         (b)      Each of the parties hereto hereby waives its respective rights
to a jury trial of any claim or cause of action based upon or arising out of
this Guaranty. The scope of this waiver is intended to be all-encompassing of
any and all disputes that may be filed in any court and that relate to the
subject matter of this Guaranty, including without limitation contract claims,
tort claims, breach of duty claims, and all other common law and statutory
claims.

         Section 4.4.  Interpretation. The headings of the sections and other
subdivisions of this Guaranty are inserted for convenience only and shall not be
deemed to constitute a part hereof. References to "Sections" refer to Sections
of this Guaranty unless explicitly stated otherwise.

purchase the Note that Parent shall have executed and delivered this Pledge
Agreement.

         NOW, THEREFORE, in consideration of the foregoing and in order to
induce Lender to enter into the Loan Agreement and the Exchange Agreement and
for other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, it is agreed as follows:

         Section 1.        Definitions. Capitalized terms used in this Pledge
Agreement without definition shall have the meanings set forth in the Loan
Agreement. The term "Event of Default" refers to a breach of the Secured
Obligations by Parent. When used herein, the term "including" means "including
without limitation."

         Section 2.        Pledge. As collateral security for the prompt
performance by Parent of its obligations under the Guaranty, Parent hereby
pledges, assigns, hypothecates and transfers to Lender (x) 1 share of the Common
Stock of Borrower held by Parent (as such number of shares may be adjusted for
stock splits, recapitalizations, stock dividends, etc.) (the "Pledged Shares")),
and (y) all proceeds (including dividends) payable in respect of the Pledged
Shares ("Proceeds") (together with the Pledged Shares, the "Pledged
Collateral"); and represents and warrants that such security interest shall,
when UCC-1 financing statements have been properly filed in the appropriate
offices, grant a first priority security interest in the Pledged Collateral in
favor of Lender.

<PAGE>   41

         Section 3.        Security for Obligations. This Pledge Agreement shall
secure, and the Pledged Collateral shall be security for, the prompt payment in
full when due, and performance of, all obligations of Parent to Lender under the
Guaranty, including the costs of collection thereof, to Lender or any assignee,
indorsee or transferee of Lender and including, without limitation, all
reasonable attorneys fees (the "Secured Obligations"). Upon the occurrence of
any Event of Default, Lender is entitled to take for its own account, or to
dispose of, the Pledged Collateral in accordance with the terms of this Pledge
Agreement.

         Section 4.        Rights of Lender. This Pledge Agreement is intended
to convey to Lender all of Parent's rights with respect to the Pledged
Collateral (including, subject to Section 7(a)(i), the right to receive monies
with respect to the Pledged Shares) and none of Parent's duties with respect
thereto. Lender shall not be liable for failure to collect or realize upon the
Secured Obligations or the Pledged Collateral, or any part thereof, or for any
delay in so doing, nor shall Lender be under any obligation to take any action
whatsoever with regard thereto. Upon the failure of Borrower to pay any amounts
owed to Lender in respect of the Secured Obligations, all or any part of the
Pledged Collateral may be registered in the name of Lender and/or a nominee of
Lender. Parent hereby authorizes Lender to take all actions necessary to
effectuate this Pledge Agreement as their attorney-in-fact and to execute any
and all documents, with or without designation of Lender's signing capacity, on
behalf of Parent in connection with all activities contemplated by this Pledge
Agreement, including, without limitation, to receive, endorse and collect,
subject to Section 7(a)(i), all instruments made payable to Parent representing
any payment or other distribution in respect of the Pledged Collateral or any
part thereof and to give full discharge for the same.

         Section 5.        Representations and Warranties of Parent. Parent
represents and warrants that:

         (a)      Parent is the legal record and beneficial owner of, and has
good and marketable title to, the Pledged Collateral, subject to no pledge,
lien, mortgage, hypothecation, security interest, charge, option or other
encumbrance whatsoever;

         (b)      Parent has full power, authority and legal right to pledge all
the Pledged Collateral pursuant to this Pledge Agreement; and

         (c)      the pledge, assignment, hypothecation, transfer and delivery
of the Pledged Collateral pursuant to this Pledge Agreement creates, when UCC-1
financing statements have been properly filed in the appropriate offices, a
valid first lien on and a fully perfected first priority security interest in
the Pledged Collateral, and the proceeds thereof, subject to no prior pledge,
lien, mortgage, hypothecation, security interest, charge, option or encumbrance
or to any agreement purporting to grant to any third party a security interest
in the Pledged Collateral except as set forth in clause (a) of this Section 5.

         Section 6.        Covenants. Parent covenants and agrees that until the
Termination Date (as defined in Section 10):


                                      -2-
<PAGE>   42

         (a)      Parent will not sell, assign, transfer, exchange or otherwise
dispose of, or grant any option with respect to, the Pledged Collateral, nor
will Parent create, incur or permit to exist any pledge, lien, mortgage,
hypothecation, security interest, charge, option or other encumbrance with
respect to the Pledged Collateral (other than the lien created by this Pledge
Agreement);

         (b)      Parent will, at its sole expense, promptly execute,
acknowledge and deliver all such instruments and take all such action as Lender
from time to time may reasonably request in order to ensure to Lender the
benefits of the liens in and to the Pledged Collateral intended to be created by
this Pledge Agreement; and

         (c)      Parent will defend the right, title and security interest of
Lender in and to the Pledged Collateral against the claim of any entity or
person and will maintain and preserve such liens until such Pledged Collateral
is released pursuant to Section 10.

         Section 7.        Parent's Rights.

         (a)      All distributions in respect of the Pledged Collateral shall
be paid to Parent but held in escrow by Lender pending maturity of the Notes;
all rights to such distributions and payments shall remain subject to the lien
created by this Pledge Agreement; provided that notwithstanding the foregoing
the Borrower may distribute the proceeds of the issuance of the Notes to the
Parent and such proceeds will not be subject to escrow or any liens hereunder;
and

         (b)      Parent hereby agrees to execute and deliver (or cause to be
executed and delivered) all such instruments as Lender may reasonably request
for the purpose of enabling Parent to exercise the rights which it is entitled
to exercise pursuant to the provisions hereof, and to receive the distributions
and payments which it is authorized to receive and retain pursuant to the
provisions hereof.

         Section 8.        Defaults and Remedies.

                  (a)      Upon any Event of Default, Lender, in addition to all
rights of Lender created under the other Loan Documents, shall have and may
exercise with respect to the Pledged Collateral, all rights and remedies
available to secured creditors under the New York Commercial Code, or otherwise
at law or in equity including, without limiting the generality of the foregoing,
(i) the right to take the Pledged Collateral (or portion thereof) for its own
account as provided in clause (b) of this Section 8 and (ii) the right to sell
or assign the Pledged Collateral, or any part thereof, at public or private sale
in New York or elsewhere as Lender may determine in good faith to be
commercially reasonable and at such prices as Lender may deem best and
commercially reasonable. The parties agree that written notice mailed to Parent
not less than ten days prior to any public sale of the Pledged Collateral or ten
days prior to the date after which any private sale or other disposition of such
Pledge Collateral will be made shall constitute reasonable notice (all other
notices, demands or advertisements of any kind being hereby expressly waived),
but notice given in any other reasonable manner or at any other reasonable time
shall be sufficient. At any such sale, Lender shall have the right to purchase
the Pledged Collateral, or any part thereof.

         To the extent Lender is restricted from making sales of Pledged
Collateral without registration under the Securities Act, the following shall
govern:

                           (i)      at any such sale, Lender, at its discretion,
may restrict the potential bidders or purchasers to institutional investors,
and/or other persons who shall represent and warrant that they are acquiring the
Pledged Collateral for their own account, for investment only and not with a
view toward the resale or distribution thereof and which will make such further
representations and warranties as Lender may, in its discretion, deem necessary
or desirable to assure Lender that such prospective bidders or purchasers are,
with respect to applicable federal and state securities laws and rules, suitable
bidders and purchasers of such Pledged Collateral;

                           (ii)     Lender may additionally decide to sell the
Pledged Collateral in one or more private sales or in such other manner and
subject to such restrictions and conditions as Lender, in its discretion, shall
deem necessary in order for such sale to be exempt from the registration
requirement of the Securities Act, and applicable state securities laws; and

                           (iii)    Parent consents to any sales made in the
manner above-described and agrees that sales made as above-described shall be
deemed to have been made in a commercially reasonable manner and Parent further
agrees that Lender shall have no obligation to delay sale of any of the Pledged
Collateral for the period of time necessary to permit the offering and sale of
such Collateral to be registered for public sale under the Securities Act, and
applicable state securities laws, and no representation is made that any such
registration is possible or will be made.

                  (b)      Upon the occurrence and during the continuation of
any Event of Default, Lender shall have the right, in lieu of selling Pledged
Collateral as provided in clause (a) of this Section 8, to take for its own
account a portion of the Pledged Collateral with an Appraised


                                      -4-
<PAGE>   44

Value (as hereinafter defined) equal to the amount of the Secured Obligations as
to which Borrower shall be in default (the "Foreclosed Collateral") upon ten
(10) days prior written notice (which notice shall state the Appraised Value
ascribed thereto). In such event, Lender shall thereafter have all right, title
and interest in and to such Foreclosed Collateral free of any liens, claims or
encumbrances and Parent's interest therein shall terminate, as if such
Foreclosed Collateral had been sold to a third party in accordance with the
procedures contemplated by clause (a) of this Section 8. "Appraised Value" shall
mean the fair market value of such Pledged Collateral on the day prior to the
date of the notice provided for herein as determined by a nationally recognized
independent investment banking firm mutually and promptly selected by Lender and
Parent. Such firm shall make its determination as promptly as possible after its
retention. In the event that Borrower and Lender are unable to agree upon a
mutually acceptable firm within 10 days after notice from Lender to Parent,
Lender may select a nationally recognized independent investment banking firm to
conduct the appraisal.

                  (c)      Any cash held by or on behalf of Lender as Pledged
Collateral and all cash proceeds received by or on behalf of Lender in respect
of any sale of, liquidation of, or other realization upon or all or any part of
the Pledged Collateral shall be applied by Lender as follows:

                           (i)      First, to the payment of the costs and
expenses of such sale or of enforcing Lender's rights under this Pledge
Agreement or the other Loan Documents, including reasonable expenses of Lender's
counsel, and all other of the expenses, liabilities and advances made or
incurred by Lender in connection therewith; and

                           (ii)     Next, to the payment of the Secured
Obligations, all in accordance with the terms and provisions of the Loan
Documents; and

                           (iii)    Finally, after payment in full of all of the
Secured Obligations, to Parent, or its successors or assigns, or to whomsoever
may be lawfully entitled to receive the same or as a court of competent
jurisdiction may direct, of any surplus then remaining from such proceeds.

         Section 9.        Waiver. No delay on the part of Lender in exercising
any power of sale, lien, option or other right hereunder, and no notice or
demand which may be given to or made upon Parent by Lender with respect to any
power of sale, lien, option or other right hereunder, shall constitute a waiver
thereof, or limit or impair Lender's right to take any action or to exercise any
power of sale, lien, option, or any other right hereunder, or prejudice Lender's
rights as against Parent in any respect.

         Section 10.       Termination. Upon payment in full of the Secured
Obligations, this Pledge Agreement shall terminate and Lender shall deliver to
Parent such instruments of assignment or other documents of transfer as shall be
reasonably requested by Parent and any instruments of assignment or documents of
transfer executed in connection therewith to release the Pledged Collateral.

         Section 11.       Miscellaneous. This Pledge Agreement shall be binding
upon Parent and their respective successors and assigns, and shall inure to the
benefit of, and be enforceable by, Lender and its successors and assigns, and
none of the terms or provisions of this Pledge Agreement may be waived, altered,
modified or amended except in writing duly signed by Lender and Parent.

         Section 12.       Severability. If for any reason any provision or
provisions hereof are determined to be invalid and contrary to any existing or
future law, such invalidity shall not impair the operation of or affect those
portions of this Pledge Agreement which are valid.

         Section 13.       Notices. Any notice required to be given hereunder

                  SECTION 6.  MISCELLANEOUS.

                  Section 6.1. Governing Law. This Agreement shall be construed
and enforced in accordance with, and governed by, the laws of the State of New
York, without regard, to the fullest extent permitted by law, to any conflict of
laws rules which might apply the laws of any other jurisdiction.

                  Section 6.2. Jurisdiction; Waiver of Jury Trial. (a) Each of

jurisdiction of (i) the state courts of the State of New York, New York County,

Note or any transactions contemplated hereby. Each of the Borrower and the
Parent, for itself and in connection with its properties, generally and
unconditionally, waives any defense of forum non conveniens, and irrevocably
agrees to be bound by any judgment rendered in connection with this Agreement.

                  (b)      Each of the parties hereto hereby waives its
respective rights to a jury trial of any claim or cause of action based upon or
arising out of this Agreement. The scope of this waiver is intended to be
all-encompassing of any and all disputes that may be filed in any court and that
relate to the subject matter of this agreement, including without limitation
contract claims, tort claims, breach of duty claims, and all other common law
and statutory claims.

                  Section 6.3. Interpretation. The headings of the sections and
other subdivisions of this Agreement are inserted for convenience only and shall

irreparable damage will result in the event that this Agreement is not

decree of specific performance, and appropriate injunctive relief may be applied
for and granted in connection therewith. Such remedies shall, however, be

which a party may have under this Agreement or otherwise.

                  Section 6.6. Assignment. This Agreement is not assignable by

                               KEEP WELL AGREEMENT

                  KEEP WELL AGREEMENT (the "Agreement") dated as of December 19,
2000 between iXL Ventures, L.P., a Delaware limited liability company (the
"Parent"), and iXL Ventures PHC, Inc., a Delaware corporation (the "Borrower").
Terms not otherwise defined herein are used as defined in the Note Purchase
Agreement.

                  WHEREAS, the Borrower is issuing 5.75% Secured Convertible
Notes (the "Notes") in a principal amount of $20 million to ProAct Technologies
Corp. (the "Company") pursuant to the terms of the Note Purchase Agreement dated
as of the date hereof between the Company and the Borrower and certain other
parties (the "Note Purchase Agreement"); and

                  WHEREAS, the Parent has transferred 10 million shares of the
Company's common stock to the Borrower, and such shares have been pledged to the
Company pursuant to the Stock Pledge Agreement dated as of the date hereof by
and between the Borrower and the Company;

                  NOW, THEREFORE, the parties hereto, for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
agree as follows:

                  Section 1.  KEEP WELL. The Parent will from time to time
promptly make such capital contributions to the Borrower as may be required for
the Borrower to meet its obligations to pay any and all interest and other
amounts due (other than principal) under the terms of the Notes and the other
Loan Documents, whenever such amounts may be due and payable, and further to
provide for payment of administrative overhead and similar expenses of operating
the Borrower from time to time, in each case so long as the Notes remain
outstanding (such obligation to make contributions, the "Keep Well Obligation");
provided that for purposes of this Agreement, the Keep Well Obligation shall
terminate with respect to Interest Obligations which no longer accrue upon the
occurrence of a Cut-Off Event. The term "Interest Obligations" means the
obligations of the Borrower to pay interest under the Notes; provided that (x)
if the principal amount of the Notes is repaid by transfer of Purchaser Shares
as provided under the terms of the Note Purchase Agreement, or (y) if the
Company has completely foreclosed upon the Pledged Collateral under the Pledge
Agreement or (z) an Event of Default has occurred, the Company has a right to
foreclose on the Pledged Collateral, there is no stay in effect preventing such
foreclosure, and the Company fails to take reasonable steps to effectuate a
foreclosure with respect to all of the Pledged Collateral (any such event in
clauses (x), (y) or (z), a "Cut-Off Event"), then, in each case, for purposes of
this Agreement, from and after a Cut-Off Event, Interest Obligations shall no
longer accrue with respect to the principal amount of the Notes (but interest
may continue to accrue with respect to unpaid interest).

                  SECTION 2.  TERM. This Agreement shall have a term beginning
on the date hereof and ending on the date that the Notes are paid in full (the
"Term").

                  SECTION 3.  MISCELLANEOUS.


<PAGE>   61

                  Section 3.1. Governing Law. This Agreement shall be construed
and enforced in accordance with, and governed by, the laws of the State of New
York, without regard, to the fullest extent permitted by law, to any conflict of
laws rules which might apply the laws of any other jurisdiction.

                  Section 3.2. Jurisdiction; Waiver of Jury Trial. (a) The
Borrower irrevocably submits to the non-exclusive jurisdiction of (i) the state
courts of the State of New York, New York County, and (ii) the United States
District Court for the Southern District of New York, for the purposes of any
suit, action or other proceeding arising out of this Agreement or any
transactions contemplated hereby. The Borrower, for itself and in connection
with its properties, generally and unconditionally, waives any defense of forum
non conveniens, and irrevocably agrees to be bound by any judgment rendered in
connection with this Agreement.

                  (b)      Each of the parties hereto hereby waives its
respective rights to a jury trial of any claim or cause of action based upon or
arising out of this Agreement. The scope of this waiver is intended to be
all-encompassing of any and all disputes that may be filed in any court and that
relate to the subject matter of this Agreement, including without limitation
contract claims, tort claims, breach of duty claims, and all other common law
and statutory claims.

                  Section 3.3. Interpretation. The headings of the sections and
other subdivisions of this Agreement are inserted for convenience only and shall
not be deemed to constitute a part hereof. References to "Sections" refer to
Sections of this Agreement unless explicitly stated otherwise. The term
"including" means "including without limitation."

                  Section 3.4. Counterparts. This Agreement may be executed in
any number of counterparts, all of which shall be considered one and the same
agreement, and shall become effective when one or more such counterparts have
been signed by each of the parties and delivered to the other parties.

                  Section 3.5. Specific Performance. The parties agree that
irreparable damage will result in the event that this Agreement is not
specifically enforced, and the parties agree that any damages available at law
for a breach of this Agreement would not be an adequate remedy. Therefore, the
provisions hereof and the obligations of the parties hereunder shall be
enforceable in a court of equity, or other tribunal with jurisdiction by a
decree of specific performance, and appropriate injunctive relief may be applied
for and granted in connection therewith. Such remedies shall, however, be
cumulative and not exclusive and shall be in addition to any other remedies
which a party may have under this Agreement or otherwise.

                  Section 3.6. Assignment. This Agreement is not assignable
without the prior written consent of the Company.

                  Section 3.7. Amendment. This Agreement may be amended,
modified or supplemented only by a written instrument duly executed by the
Parent, the Company and the Borrower.

                  Section 3.8. Third Party Beneficiary. The Company is a third
party beneficiary to this Agreement and may enforce the terms of this Agreement.
