                           (1)      Advances.

                                    (A) The Initial Advance. The initial advance
of the Tax Loan shall be made in the form of a check drawn for the benefit of
the Department of Treasury for federal income taxes, and the appropriate state
tax authority for state income taxes following WVM's delivery to, and review by
Bonfield and an accountant or an accounting firm reasonably acceptable to
Bonfield, of a copy of the form 4868 (and the similar state extension form), for
an extension of time within which to file federal and state income tax returns,
which WVM and HGM intend to file, jointly, with respect to the 2000 calendar
year, prepared and/or reviewed by an accountant or accounting firm reasonably
acceptable to Bonfield, showing the estimated income taxes due for 2000 calendar
year, after application of all credits and withholdings.

                                            (i) Refunds of the Initial Advance.
WVM shall provide Bonfield with executed final copies of the 2000 form 1040 and
comparable state form (the "Final 2000 Forms") within 10 days of their filing.
If a Final 2000 Form shows an overpayment of taxes, such overpayment shall be
claimed as a refund, and not claimed as an estimated payment for the year 2001.
WVM and HGM hereby agree to deliver to Bonfield, immediately upon the receipt
thereof, such refund as a payment on the Tax Note. Failure to so return within
three (3) business days after receipt thereof shall constitute an Event of
Default under the Tax Note and an Event of Termination under this Agreement.

                                    (B) Subsequent Advances for Tax Payments.
For calendar years 2001 and following (each an "Income Year"), so long as the
Tax Loan is outstanding, and no Event of Default under the Tax Note, or Event of
Termination hereunder (whether or not declared) has occurred, WVM may request
that Bonfield advance to him additional funds to pay federal and state income
taxes, under the terms of this Section 3.1(a)(1)(B)(i).

                                            (i) If WVM intends to request an
advance from Bonfield under this Section 3.1(a)(1)(B), then no later than March
15 of the year after the Income Year (the "Payment Year"), WVM shall provide to
Bonfield (x) a copy of the draft form 1040 (or comparable state form), for
federal and state income taxes, that he intends to file with respect to the
Income Year, prepared by an accountant or accounting firm reasonably acceptable
to Bonfield (the "Tax Accountant"), showing the income taxes due for the Income
Year, after application of all credits and withholdings (the "Actual

                                      S-8
<PAGE>   10
Tax") and (y) a pro forma calculation of federal and state income taxes,
prepared by the Tax Accountant, that would have been payable with respect to the
relevant Income Year, if the recognized gain or loss related to the sale or
other disposition of the Collateral (which shall not include the exercise of any
Options), were excluded (the "ProForma Tax"). Solely for the purposes of this
section 3.1(a)(1)(B)(i), for the 2001 Income Year, gain or loss related to the
sale or other disposition of the Collateral shall include the gain or loss on
the disposition of the assets listed on Schedule 3.1 attached hereto. Bonfield,
through its employees and representatives, shall be entitled to review such
returns and calculations and discuss the propriety of such calculations with the
Tax Accountant.

                                            (ii) If WVM has requested an advance
under this section 3.1(a)(1)(B), Bonfield shall, no later than April 15 of the
Payment Year, advance to WVM the amount by which the Actual Tax exceeds the Pro
Forma Tax for the Income Year, as an advance under the Tax Note; provided,
however, that advances to WVM in any Payment Year shall not be more than the
amount by which the proceeds from the sale of Collateral received by Bonfield
during the relevant Income Year reduced the principal on the Tax Note.

                                            (iii) Advances under this section
shall be made in the form of a check drawn for the benefit of the Department of
Treasury for federal income taxes, or the appropriate state tax authority for
state income taxes.

                                            (iv) If the final form 1040 (or
comparable state forms) are not completed by April 15 of the relevant Payment
Year, the amount of advances under section 3.1(a)(1)(B)(ii) shall be determined
based on good faith estimates prepared by the Tax Accountant, evidenced on form
4868 (and the similar state extension form), and the calculation shall be
finalized when final tax returns for the Income Year are prepared, and if
necessary additional funds advanced to WVM under the terms of this section. Any
refunds available to WVM (or his spouse, to the extent they have filed jointly
with respect to any subsequent Income Year) because of overpayment based on the
estimates shall be promptly be returned to Bonfield. Failure to so return within
three (3) business days after receipt thereof shall constitute an Event of
Default under the Tax Note and an Event of Termination under this Agreement.

                           (2) Maturity Date. The Tax Note shall be payable
(subject to mandatory prepayments, as required pursuant to Section 3.1(a)(3)(B)
below), on demand, at any time after April 30, 2001 against WVM. Notwithstanding
the foregoing, on the Phase II Effective Date, obligations outstanding under the
Tax Note shall be consolidated into the Amended and Restated Note.

                           (3) Payments.

                                    (A) Voluntary Payments. WVM may, at his
option, prepay the Tax Note in whole or in part, at any time, without any
premium or penalty.

                                    (B) Mandatory Prepayments. The Tax Note
shall be mandatorily repaid from the following funding sources subject to the
provisions of the Option Note and Section 4.2(c) hereof.:

                                            (i) SFE shall offset the amount of
$300,000 against SFE's obligation to pay the Retention Bonus, and such proceeds
shall be applied to reduce the obligations outstanding under the Tax Note and
other Outstanding Obligations;

                                            (ii) all proceeds, as and when
received with respect to all payments made after the date hereof, in connection
with the Lubert Asset Purchase; and

                                      S-9
<PAGE>   11
                                            (iii) all proceeds received from the
sale, financing or other disposition of any of the Collateral and the exercise
of rights and remedies under the Existing Documents.

                                    (C) Application of Payments. Each such
prepayment, including any voluntary and mandatory prepayments, shall be applied
first to outstanding accrued interest and then to the remaining outstanding
principal balance of the Tax Note.

                           (4) Interest. Interest on the outstanding principal
balance of the Tax Note shall accrue at a rate of seven percent (7%) per annum
and shall accrue and be capitalized annually, on each anniversary of the date of
such Tax Note.

                  (b) Collateral; Credit Enhancements. The Tax Note and the
other Outstanding Obligations shall be secured by a first priority lien (with
respect to the Vassar Street Property, subject to the MIT Existing Mortgage and,
if the MIT Financing is consummated, a mortgage securing the MIT Financing) on
all of the Collateral; provided, however, that until the later of the Phase II
Effective Date or the date on which WVM's obligations to Legg Mason have been
satisfied, Bonfield's security interest in WVM Legg Mason Account shall be
subordinate to the security interest in favor of Legg Mason. The Tax Note shall
also be secured by the Existing Mortgages and, if and to the extent but only if
and to the extent secured prior to execution of this Agreement, the HGM
Guaranty, on a non-recourse basis, pursuant to the terms of such HGM Guaranty.

                  (c) Transfers; Asset Liquidation. In addition to, and not
in substitution for Bonfield's rights as a secured party in accordance with
Section 3.1(b) hereof and as provided in the Security Agreement, the Control
Agreements, the New Mortgages and the Existing Documents, Bonfield may elect, on
an item by item basis, to transfer title to, or mortgage, refinance, or
otherwise monetize any or all of WVM's interests in (or those of any WVM
Entity), the Collateral and the property subject to the Existing Agreements to
Bonfield or a designee of Bonfield, in reduction of the outstanding balance
under the Tax Note, subject, in any event, to the provisions of Section 3.1(f)
hereof, and in accordance with the provisions of this Section 3.1(c).

                           (1) Bonfield or a designee, may, at any time prior to
repayment in full of all of the obligations under the Tax Note, and from time to
time, purchase from WVM or the applicable WVM Entity, free and clear of all
liens, claims and encumbrances of any nature other than Permitted Encumbrances,
one or more of the assets included in the Collateral. The purchase price for
each such asset shall be the value ascribed thereto on Exhibit 1.1 and shall be
payable by crediting the amount thereof against the Tax Note or other
Outstanding Obligations, in such order and amounts as Safeguard shall determine,
in its sole discretion. With respect to all Collateral other than real property
(for which the applicable notice period shall be thirty (30) days), Bonfield
shall provide WVM or the applicable WVM Entity with ten (10) days' prior written
notice of its intent to effect a conveyance of the asset, including in such
notice a description of the asset, the purchase price, the intended date of
conveyance and the identity of the party acquiring title, if not Bonfield. WVM
or the applicable WVM Entity shall forward to Bonfield, not less than three (3)
days prior to the intended date of conveyance, such documents and evidence of
the conveyance as Bonfield shall reasonably request, based on the nature of the
asset to be conveyed. Upon Bonfield's or the applicable designee's receipt of
all required documents and instruments, including, without limitation, title
documents, consents, confirmation of required notices, certificates or other
similar documents, it shall credit the purchase price as provided hereinabove.

                           (2) To the extent that any asset which would
otherwise be conveyed to Bonfield or a designee is not capable of being sold,
assigned, transferred, conveyed or delivered because a necessary consent or
release can not be obtained by the intended transfer date (a "Non-Transferable

                                      S-10
<PAGE>   12
Asset"), WVM and each WVM Entity shall use its respective reasonable best
efforts to obtain such consent or release.

                           (3) Notwithstanding anything to the contrary herein,
Bonfield shall not be obligated to purchase any Non-Transferable Asset without
WVM or the applicable WVM Entity first having obtained all necessary consents,
removed or eliminated any such potential defaults under any agreements affecting
any such asset without adversely modifying, amending or burdening such
Non-Transferable Asset; provided however, that WVM's or the applicable WVM
Entity's failure to effect the conveyance within the period set forth in the
initial notice required pursuant to Section 3.1(c)(1) hereof, shall, at
Bonfield's election, constitute an Event of Default under the Tax Note, an Event
of Termination under this Agreement.

                  (d) Application of Proceeds. The proceeds of any exercise
by Bonfield of its remedies with respect to the Collateral, whether as a secured
party, pursuant to Section 3.1(b) hereof, or as a purchaser, pursuant to Section
3.1(c) hereof, will be applied as a mandatory prepayment of the Tax Note.
Bonfield may exercise such remedies before, on or after January 1, 2003, whether
or not demand has been made in respect of the Tax Note or any other Outstanding
Obligation.

                  (e) Excess Proceeds From Collateral. In the event Phase
II is not consummated, and in the event Safeguard realizes proceeds (net of any
and all taxes, tax advances and expenses of sales payable in connection
therewith and reasonable counsel fees incurred in connection therewith) from the
Collateral in excess of the amounts owing under the Notes and any other
Outstanding Obligations, such excess shall be returned to WVM (or, if WVM is
then not living, to HGM) upon the expiration of all periods during which any
such proceeds could be subject to avoidance under any applicable preference or
fraudulent conveyance laws or Legal Requirements of similar import then in
effect.

                  (f) Forbearance. Safeguard will forbear from (i)
demanding immediate payment of all amounts due under the Letter Agreement or the
Tax Note, including without limitation, interest, fees, costs, charges,
expenses, indemnities or other sums chargeable to WVM under the Existing
Documents; (ii) exercising any of its rights and remedies under the Existing
Documents as a result of WVM's failure to comply with the terms of the Letter
Agreement and the Existing Security Agreement prior to the date hereof; and
(iii) exercising its rights and remedies with respect to the collateral security
granted pursuant to Section 3.1(b) hereof; provided, however, that such
forbearance shall continue only until the earliest of (i) the Phase II Effective
Date, (ii) April 30, 2001 or (iii) the declaration of an Event of Termination
(as defined in Article V of this Agreement). The declaration of an Event of
Termination shall immediately operate to terminate Safeguard's agreement to
forbear hereunder. Upon such termination, Safeguard shall have no further
obligations to forbear hereunder.

                  (g) Agreement as to Treatment of Existing Mortgages. Safeguard
shall deposit into escrow, pursuant to the FROF Escrow Agreement, releases with
respect to the Existing Mortgages, with such release to be effective as of the
Phase II Effective Date.

                  (h) HGM Actions. HGM shall resign, effective immediately
upon receipt of $50,000 in prepaid fees payable under a Letter dated the date
hereof to MegaSystems, Inc. relating to the provision by HGM of consulting
services, as director and officer of MegaSystems, Inc., and from any and all
positions she holds with MegaSystems, Inc. and in connection therewith shall
cause her office to be relocated to a premises other than 435 Devon Park Drive,
Wayne, Pennsylvania, on or before April 25, 2001.

                  (i) Consent of Third Parties. WVM will seek and obtain
the consent of each third party necessary to effect or complete the transactions
contemplated by Phase I and Phase II of this

         Upon the satisfaction of the Phase II Conditions as set forth in

         Section 4.1 Restructure of Legg Mason Debt. As of the Phase II
Effective Date, Safeguard will restructure the Outstanding Obligations, to be
evidenced by a new Amended and Restated Note which shall amend, restate and
consolidate (i) the Tax Note; and (ii) the Outstanding Obligations arising under
the Legg Mason Guaranty and the Letter Agreement.

                  (a) Advances.

                           (1) The Initial Advance. The initial advance of the
Amended and Restated Loan shall be made in the form of payment by Bonfield, via
wire or electronic transfer, to Legg Mason of funds sufficient to satisfy WVM's
then remaining obligations to Legg Mason in connection with the Legg Mason
Accounts.

                           (2) Subsequent Advances for Tax Payments. For
calendar years 2001 and following (each an "Income Year"), so long as the
Amended and Restated Loan is outstanding, and no Event of Default under the
Amended and Restated Note, or Event of Termination hereunder (whether or not
declared) has occurred, WVM may request that Bonfield advance to him additional
funds to pay

                                      S-14
<PAGE>   16
federal and state income taxes, under the Amended and Restated Note. The terms
and conditions of such additional advances shall be as set forth in Section
3.1(a)(1)(B) hereof; provided that all references therein to the "Tax Note"
shall be deemed to be references to the "Amended and Restated Note" for purposes
of this Section.

                           (3) Advances for Transaction fees. Contemporaneously

                  (c) Payments.

                           (1) Voluntary Payments. WVM may, at his option,

                           (2) Mandatory Prepayments. The Amended and Restated
Note shall be mandatorily repaid from the following funding sources:

                                    (A) To the extent the same had not been used
to reduce obligations outstanding under the Tax Note, SFE shall offset the
amount of $300,000 against SFE's obligations to pay the Retention Bonus and such
proceeds shall be applied to reduce the obligations outstanding under the
Amended and Restated Note and any other Notes then outstanding;

                                    (B) all proceeds, as and when received with

<PAGE>   17
Security Agreement, the Control Agreement, the New Mortgages and such of the
Existing Documents as will continue, but only to the extent they continue, in
effect following the Phase II Effective Date, Bonfield may elect, on an item by
item basis, to cause WVM to transfer title to, any or all of his interests (or
those of any WVM Entity) in the Collateral and the property subject to the
Existing Agreements to Bonfield, or a designee of Bonfield, in reduction of the
outstanding balance under the Notes. Any such conveyances shall be made in
accordance with the provisions of Section 3.1(c) hereof.

                  (f) Excess Proceeds from Collateral. In the event
Safeguard realizes proceeds (net of any and all taxes, tax advances and expenses
of sales payable in connection therewith and reasonable counsel fees incurred in
connection therewith) from the Collateral in excess of the amounts owing under
the Notes, such excess shall be returned to WVM (or, if WVM is then not living,
to HGM) upon the expiration of all periods during which any such proceeds could
be subject to avoidance under any applicable preference or fraudulent conveyance
laws or Legal Requirements of similar import then in effect.

         Section 4.2 SFE Option.

                  (a) At any time at which the Market Price (as defined
below) of a share of SFE Common Stock is equal to or greater than the per share
exercise price under the SFE Option and WVM is not in default hereunder or under
any of the Related Documents, WVM shall have the right to give notice to SFE of
his intent, subject to Bonfield's making the loan described below, to exercise
all but not less than all of the SFE Option (a "Conditional Exercise," and the
shares issuable on exercise being called the "Exercise Shares"), which notice
shall specify the amount not to exceed the aggregate exercise price of the
Exercise Shares (the "Option Price"), which WVM wishes to borrow from Bonfield
pursuant to the Option Note to pay such Option Price for such Conditional
Exercise. On receipt of a notice of Conditional Exercise, Safeguard shall use
its commercially reasonable efforts to obtain all consents and waivers, if any,
which are required under any loan agreements, other financing arrangements,
contracts or otherwise to permit Bonfield to make loans under the Option Note
without committing a default or event which, with the passage of time or giving
of notice or both would constitute a default under any such agreement,
arrangement, contract or otherwise (collectively, the "Option Loan Consents").
Subject to and upon receipt of the Option Loan Consents, Bonfield shall loan to
WVM an amount equal to the Option Price (the "Option Loan"), pursuant to, and to
be evidenced by, the Option Note, which Note shall be in the maximum aggregate
principal amount of the Option Price, shall be secured by all of the Collateral,
and shall be in the form of Exhibit A-2 hereto. In the event the Option Loan
Consents cannot be obtained within thirty (30) days of SFE's receipt of the
Notice of Conditional Exercise, the Conditional Notice shall be deemed null and
void and neither SFE nor Bonfield shall have further obligation in respect of
such Conditional Exercise. The Option Loan shall be paid by Bonfield directly to
SFE (with WVM paying simultaneously in cash any portion of the Exercise Price he
elects to pay in cash) in consideration of the payment of the Option Price for
the Exercise Shares under the applicable Conditional Exercise and the
certificates respecting the Exercise Shares, shall be issued in the name of WVM,
and shall be delivered directly to Bonfield to be held pursuant to the Amended
and Restated Security Agreement. WVM hereby expressly authorizes such payment
and delivery. WVM further expressly acknowledges and agrees that SFE shall not
have any liability to him or anyone claiming on behalf or through him (i) for
any delay in obtaining or inability or failure to obtain the Option Loan
Consents or (ii) for any delay in making or inability or failure to make the
Option Loan except Bonfield's willful refusal to fund after receipt of the
Option Loan Consents and fulfillment of all other notices, procedures,
conditions and requirements set forth in this Section 4.2, including, without
limitation, in either event any additional tax payable or decline in market
value occasioned by any changes in the Market Price. In the event at any time
between SFE's receipt of notice of a Conditional Exercise and the making of the
Option Loan, the Market Price shall be less than the Option Price, such
Conditional Exercise shall be deemed withdrawn and null and void without further
action by either WVM or SFE. For purposes of this Section, the term

                                      S-16
<PAGE>   18
"Market Price" shall mean, on any day, the closing price of SFE Common Stock for
the preceding day as reported on the New York Stock Exchange.

                  (b) SFE acknowledges that the first two sentences of
Paragraph 9 of the Stock Option Grant Certificate evidencing the SFE Option will
not apply to the transactions contemplated by this Agreement. Each of WVM and
HGM agrees with this acknowledgement and agrees that SFE may amend or otherwise
modify the SFE Option in any respect, without his or her consent, to the extent
necessary to perfect or improve Bonfield's security interest in the SFE Option,
the shares underlying the SFE Option or any proceeds from the sale of those
shares.

                  (c) The Option Note shall be a partial-recourse obligation of
WVM, in accordance with its terms until April 30, 2006, after which it shall
constitute a general and direct obligation of WVM, with full recourse to all of
his personal assets, except to the extent of the Non-Recourse Compensation. So
long as any portion of the Option Note the comprises a recourse obligation of
WVM shall remain outstanding, Bonfield acknowledges that all payments or offsets
made pursuant to or in accordance with the terms of this Agreement shall be
applied or allocated to reduce interest on and the principal balance of such
recourse obligations under the Option Note before same shall be applied or
allocated to any other obligations.

         Section 4.3 Release of Escrow Items. Upon the satisfaction or waiver of
each of the Phase II Conditions, each of Bonfield, through its counsel, WVM and
HGM shall notify FROF, in accordance with the terms of the FROF Escrow
Agreement, that the Phase II Effective Date has occurred. Upon receipt of all
such required notices, FROF shall release the documents held in escrow strictly
in accordance with the terms of the FROF Escrow Agreement.

         Section 4.4 Lake Naomi Option. HGM shall have an option to purchase the
real property and improvements thereon located at 138 Woodland Avenue, Pocono
Pines (Lake Naomi), Pennsylvania (the "Lake Naomi Property") for a purchase
price of the lower of (a) $500,000 or (b) the fair market value of the property,
as determined by an appraiser satisfactory to Safeguard (the "Option Price")
which option shall be exercised and the purchase price paid to Bonfield on or
before the Phase II Effective Date and, if not so exercised, the option shall be
deemed cancelled and shall thereafter be null and void.
