the Company and Stockholders there is no basis for any such valid claim or
action.

            3.17. Taxes.
                  -----

                  (a) All Federal, foreign, state, county and local and other
Taxes due from Invisions Group or the Company on or before the Closing have been
paid and all Tax Returns which are required to be filed by Invisions Group or
the Company on or before the date hereof have been filed within the time and in
the manner provided by all Requirements of Laws or extensions were timely filed,
and all such Tax Returns are true and correct and accurately reflect the Tax
liabilities of Invisions Group and the Company in substantially all respects. No
Tax Returns of the Company or Invisions Group are presently subject to an
extension of the time to file. All Taxes, assessments, penalties, and interest
of Invisions Group or the Company which have become due pursuant to such Tax
Returns or any assessments received have been paid or adequately accrued on the
Financial Statements. The provisions for Taxes reflected on the balance sheets
contained in the Financial Statements are adequate to cover all of Invisions
Group and the Company's Tax liabilities for the respective periods then ended
and all prior periods. Neither Invisions Group or the Company has executed any
presently effective waiver or extension of any statute of limitations against
assessments and collection of Taxes, and, to the Knowledge of the Stockholders
or the Company, there are no pending or threatened claims, assessments, notices,
proposals to assess, deficiencies, or audits with respect to any such Taxes. For
Governmental Bodies with respect to which neither Invisions Group nor the
Company files Tax Returns, no such Governmental Body has given Invisions Group
or the Company written notification that such corporation is or may be subject
to taxation by that Governmental Body. Invisions Group and the Company have
withheld and paid all Taxes required to have been withheld and paid in
connection with amounts paid or owing to any employee, Stockholder, creditor,
independent contractor or other party. Invisions Group and the Company have each
properly reflected for tax purposes in accordance with all Requirements of Laws
the status of all independent contractors, consultants and subcontractors. There
are no Tax liens on any of the property or assets of Invisions Group or the
Company.

                  (b) Neither the Company, Invisions Group nor any other
corporation has filed an election under Section 341(f) of the Code that is
applicable to Invisions Group, the Company or any assets held by the Company.
Neither Invisions Group nor the Company has made any payments, is obligated to
make any payments, or is a party to any agreement that under certain
circumstances could obligate it to make any payments that will not be deductible
under Code Sec. 280G. Neither Invisions Group nor the Company has been a United
States real property holding corporation within the meaning of Code Sec.
897(c)(2) during the applicable period specified in Code Sec. 897(c)(1)(A)(ii).
Neither Invisions Group or the Company is a party to any Tax allocation or
sharing agreement. During the past seven years, each of Invisions Group and the
Company has not and has never been (nor does Invisions Group or the Company

                                      -19-

have any liability for unpaid Taxes because it once was) a member of an
affiliated group during any part of which return year any corporation other than
Invisions Group or the Company also was a member of the affiliated group.

                  (c) No transaction contemplated by this Agreement is subject
to withholding under Section 1445 of the Code and no stock transfer taxes, real
estate transfer taxes or similar taxes will be imposed upon the sale of the
Existing Shares pursuant to this Agreement.

                  (d) The Company and Invisions Group have each never made a
valid election under Section 1362 of the Code and any corresponding state or
local provisions to be an S corporation within the meaning of Section 1361 of
the Code for all taxable years (or portions thereof) since inception. Neither
Invisions Group nor the Company has, in the past ten (10) years, (i) acquired
assets from another corporation in a transaction in which the Company's Tax
basis for the acquired assets was determined in whole or in part by reference to
the Tax basis of the acquired assets (or any other property) in the hands of the
transferor or (ii) acquired the stock of any other corporation that is a
qualified subchapter S subsidiary.

                  (e) Neither Invisions Group nor the Company will be required
to include any amount in taxable income or exclude any item of deduction or loss
from taxable income for any taxable period (or portion thereof) ending after the
Closing Date (i) as a result of a change in method of accounting for a taxable
period ending on or prior to the Closing Date: (ii) as a result of the
Acquisition contemplated hereby, (iii) as a result of any "closing agreement,"
as described in Code (S) 7121 (or any corresponding provision of state, local or
foreign income Tax law) entered into on or prior to the Closing Date, (iv) as a
result of any sale reported on the installment method where such sale occurred
on or prior to the Closing Date, or (v) as a result of any prepaid amount
received on or prior to the Closing Date.

Court Orders applicable to its business and has filed with the proper
Governmental Bodies all material statements and reports required by all
Requirements of Laws, Governmental Permits and Court Orders to which Empyrean
Holdings or any of its employees (because of their activities on behalf of
Empyrean Holdings) are subject and (ii) conducted its business and is in
compliance in all material respects with all federal, state and local energy,
public utility, health, safety and environmental Requirements of Laws,
Governmental Permits and Court Orders including the Environmental and OSHA
Obligations and all other Governmental Body requirements, except where any such
failure to comply or file would not, in the aggregate, have a material adverse
effect on Empyrean Holdings. No claim has been made by any Governmental Body
(and, to the knowledge of Empyrean Holdings, no such claim is reasonably
anticipated) to the effect that its business fails to comply, in any material
respect, with any Requirements of Laws, Governmental Permit or Environmental and
OSHA Obligation or that a Governmental Permit or Court Order is necessary in
respect thereto.

            4.13. Claims and Proceedings. There are no material claims, actions,
                  ----------------------
suits, proceedings, or investigations pending or, to the knowledge of Empyrean
Holdings, threatened against or affecting Empyrean Holdings or any of its
properties or assets, at law or in equity, before or by any court, municipality
or other Governmental Body. Empyrean Holdings is not currently subject to any
Court Order, stipulation, or consent of or with any court or Governmental Body.
No inquiry, action or proceeding has been instituted or, to the knowledge of the
Empyrean Holdings, threatened or asserted against BSG or Empyrean Holdings to
restrain or prohibit the carrying out of the Acquisition or to challenge the
validity of the Acquisition or any part thereof or seeking damages on account
thereof. To the knowledge of Empyrean Holdings there is no basis for any such
valid claim or action.

            4.14. Taxes. All Federal, foreign, state, county and local and other
                  -----
Taxes due by Empyrean Holdings on or before the Closing have been paid and all
Tax Returns which are required to be filed by Empyrean Holdings on or before the
date hereof have been filed within the time and in the manner provided by all
Requirements of Laws or extensions were timely filed, and all such Tax Returns
are true and correct and accurately reflect the Tax liabilities of Empyrean
Holdings in substantially all respects. For Governmental Bodies with respect to
which neither BSG nor Empyrean Holdings files Tax Returns, no such Governmental
Body has given BSG or Empyrean Holdings written notification that such
corporation is or may be subject to taxation by that Governmental Body. There
are no Tax liens on any of the property or assets of BSG or Empyrean Holdings.

            4.15. Information Furnished. Empyrean Holdings has made available to
                  ---------------------
the Stockholders true and correct copies of all material corporate records of
Empyrean Holdings and all other items referred to in Article IV of this
                                                     ----------
Agreement, and neither this Agreement, the Exhibits hereto, nor any written
information, instrument, or document delivered to the Stockholders pursuant to
this Agreement contains any untrue statement of a material fact or omits any
material fact necessary to make the statements herein or therein, as the case
may be, not misleading.

nor any of their representatives, shall solicit, encourage or discuss any
Acquisition Proposal (as hereinafter defined) or supply any non-public

                 ---------------------
and the Company agree that it will give, or cause to be given, to Empyrean
Holdings and its representatives, during normal business hours and at Empyrean
Holdings' expense, reasonable access to the Company's personnel, independent
accountants, officers, agents, employees, assets, properties, titles, contracts,
corporate minute and other books, records, files and documents of the Company
with respect to the Business (including financial, tax basis, budget

may reasonably request) upon 24 hours prior notice. The Stockholders and
Empyrean Holdings shall mutually agree on the timing and manner of contact with
all third parties, including, but not limited to, customers, vendors or
suppliers, which contact shall not be unreasonably withheld. Empyrean Holdings
shall not be given access to any information where the provision of such
information would violate a law or regulation applicable to the Company.


                                   ARTICLE VI
                             POST-CLOSING COVENANTS

            6.1. General. In case at any time after the Closing any further
                 -------
action is legally necessary or reasonably desirable (as determined by Empyrean
Holdings and Stockholders) to carry out the purposes of this Agreement, each of
the parties will take such further action (including the execution and delivery
of such further instruments and documents) as any other party reasonably may
request, all at the sole cost and expense of the requesting party (unless the
requesting party is entitled to indemnification therefor under Article VIII
below). The Stockholders acknowledge and agree that from and after the Closing,
the Company will be entitled to possession of all documents, books, records,
agreements, and financial data of any sort relating to the Company, which shall
be maintained at the chief executive office of the Company; provided, however,
that Stockholders shall be entitled to reasonable access to and to make copies
of such books and records at their sole cost and expense and the Company will
maintain all of the same for a period of at least three (3) years after Closing.
Thereafter, the Company will offer such documentation to Stockholders before
disposal thereof. By execution of this Agreement, the Stockholders hereby convey
all of their rights to any Intellectual Property reasonably related to the
Business to the Company and such Stockholders will, upon reasonable request,
agree to execute and deliver any other documents or instruments necessary to
effect such conveyance to the Company.

<PAGE>

            6.2. Transition. For a period of four (4) years following Closing,
                 ----------
the Majority Sellers will not take any action (or cause any such action to be
taken by another Person) that primarily has the effect of discouraging any
vendor, lessor, licensor, customer, contractor, subcontractor, supplier, or
other business associate of the Company from maintaining the same business
relations with the Company after the Closing as it maintained with the Company
prior to the Closing. For a period of four (4) years following Closing, the
Majority Sellers will refer all customer inquiries relating to the Business to
the Company.

            6.3. Confidentiality. The Stockholders will treat and hold in
                 ---------------
confidence and not disclose all Confidential Information and refrain from using
any of the Confidential Information except in connection with this Agreement or
otherwise for the benefit of the Company or Empyrean Holdings for a period of
four (4) years from the date of this Agreement, and deliver promptly to Empyrean
Holdings or destroy, at the written request and option of Empyrean Holdings, all
tangible embodiments (and all copies) of the Confidential Information which are
in their possession except as otherwise permitted herein. In the event that any
Stockholder is requested or required (by oral question or written request for
information or documents in any legal proceeding, interrogatory, subpoena, civil
investigative demand, or similar legal proceeding) to disclose any Confidential
Information, such Stockholder will notify the Company and Empyrean Holdings
promptly of the request or requirement.

            6.4. [Intentionally Left Blank].
                 --------------------------

            6.5. Additional Matters.
                 ------------------

                  (a) Tax Returns for Periods Ending on or Before the Closing
                      -------------------------------------------------------
Date. The Company and Invisions Group, in consultation with and at the direction
----
of the Majority Sellers, shall cause AA to prepare and file with the appropriate
governmental authorities, in a manner consistent with governing law, all Tax
Returns required to be filed by the Company or Invisions Group for any taxable
period ending on or prior to the Closing Date and the Company and Invisions
Group shall remit to the appropriate governmental authorities any Taxes due with
respect to such periods (which Taxes, to the extent incurred on or prior to
September 30, 1999, shall have been provided for on the Financial Statements of
the Company and Invisions Group as set forth in Section 3.7 of this Agreement).
In addition, at any time and from time to time the Company and Invisions Group,
in consultation with and at the direction of the Majority Sellers, and in a
manner consistent with governing law, shall cause AA to prepare and file such
Tax Returns for the Company and/or Invisions Group, including without limitation
any amended return or claim for refund, with respect to any taxable period or
periods ending on or prior to the Closing Date. All refunds or payments due to
the Company and/or Invisions Group from such Tax Returns, including without
limitation any amended return or claim for refund, shall promptly be paid to the
Stockholders (in the proportions provided for in Exhibit G hereto) as additional
consideration for Empyrean Group's acquisition of the Existing Shares. The cost
of preparation for all such Tax Returns shall be paid by the Company. The
Majority Sellers shall provide drafts prepared by AA of the completed Tax
Returns for the Company and Invisions Group for the taxable periods ending on or
prior to the Closing Date to Empyrean Holdings for its review a reasonable time
prior to the filing of such Tax Returns, and shall permit Empyrean Holdings to

                                      -29-
<PAGE>

comment on such Tax Returns, and in consultation with AA shall make such
revisions as are reasonably requested by Empyrean Holdings prior to filing
(provided, with respect to such Tax Returns, that any revision requested by
Empyrean Holdings must be consistent with governing law). Empyrean Holdings, the
Company, Invisions Group and the Majority Sellers (a) have not made, and agree
not to make, any election under Section 172(b)(3) with respect to the Company
NOL (as defined below) and (b) agree to use commercially reasonable efforts,
consistent with governing law, to ensure that the Stockholders receive the
maximum possible refunds or other payments under this Section 6.5(a).

                  (b) Tax Benefits from Company NOL Used in Periods Ending After
                      ----------------------------------------------------------
the Closing Date. The Majority Sellers and Empyrean Holdings shall direct AA to
----------------
determine any net operating loss carryforward or tax credit carryforward of the
Company and Invisions Group (a) from the issuance of the Option Shares or (b)
arising in the periods ending on or prior to the Closing Date (collectively, the
"Company NOL") that is not used by the Company or Invisions Group in any taxable
period ending on or prior to the Closing Date. Empyrean Holdings shall cause AA
to prepare and file with the appropriate governmental authorities, in a manner
consistent with governing law, all Tax Returns required to be filed by Empyrean
Holdings, the Company or Invisions Group for all taxable periods ending after
the Closing Date and Empyrean Holdings shall remit to the appropriate
governmental authorities any Taxes due with respect to such periods. To the
extent that all or any portion of the Company NOL is used by any of Empyrean
Holdings, the Company, Invisions Group, or any other member of the affiliated
group in which any of them is a member, to reduce taxable income for any taxable
period(s) ending after the Closing Date, Empyrean Holdings shall promptly pay to
the Stockholders (in the proportions provided for in Exhibit G hereto), as
                                                     ---------
additional consideration for Empyrean Group's acquisition of the Existing
Shares, an amount equal to the Tax Benefit arising from or attributable to such
use of all or any portion (as the case may be) of the Company NOL for such
period(s). For so long as any portion of the Company NOL remains unused,
Empyrean Group shall provide drafts of the completed Tax Returns for the taxable
periods ending after the Closing Date to the Majority Sellers for their review a
reasonable time prior to the filing of such Tax Returns, and shall permit the
Majority Sellers to comment on such Tax Returns, and in consultation with AA
shall make such revisions as are reasonably requested by the Majority Sellers
prior to filing (provided, with respect to such Tax Returns, that any revision
requested by the Majority Sellers must be consistent with governing law). In the
event the Tax Benefit arising from or attributable to the use of the Company NOL
is subsequently reduced by virtue of the action of a Taxing Authority, so that
Empyrean Holdings, the Company or the Invisions Group is required to pay a
portion of said Tax Benefit to the Taxing Authority, the Stockholders (in the
proportions provided for in Exhibit G hereto) shall pay to Empyrean Holdings an
amount equal to the portion of said Tax Benefit paid to said Taxing Authority,
together with any interest thereon that was paid to said Taxing Authority. The
Stockholders shall make such payment to Empyrean Holdings within thirty (30)
days after Empyrean Holdings has notified them in writing of such payment to a
Taxing Authority.

            "Tax Benefit" means, with respect to any taxable period ending after
the Closing Date, an amount equal to the actual reduction in state and federal
income taxes realized by

                                      -30-
<PAGE>

Empyrean Holdings, the Company or Invisions Group, or any Affiliates of Empyrean
Holdings, the Company or Invisions Group, by virtue of the use, in the
calculation of taxable income for such taxable period, of all or any portion of
the Company NOL.

                  (c) Access and Retention of Records. Empyrean Holdings and
                      -------------------------------
Stockholders recognize that each of them will need access, from time to time,
after the Closing Date, to certain accounting and Tax records and information
held by Empyrean Holdings and/or the Company to the extent such records and
information pertain to events occurring on or prior to the Closing Date;
therefore, Empyrean Holdings agrees to cause the Company to (A) use its
---------
commercially reasonable best efforts to properly retain and maintain such
records for a period of six (6) years from the date the Tax Returns for the year
in which the Closing occurs are filed or until the expiration of the statute of
limitations with respect to such year, whichever is later, and (B) allow each
Stockholder and his agents and representatives at times and dates mutually
acceptable to the parties, to inspect, review and make copies of such records as
such other party may deem necessary or appropriate from time to time, such
activities to be conducted during normal business hours and at the requesting
party's expense.

            6.6. Litigation Support. In the event and for so long as any party
                 ------------------
is actively contesting or defending against any claim, suit, action or charge,
complaint, or demand in connection with (i) any transaction contemplated under
this Agreement or (ii) any fact, circumstance, status, condition, activity,
practice, occurrence, event, action, failure to act, or transaction on or prior
to the Closing Date involving the Company, each of the other parties will
cooperate and make reasonably available themselves or their personnel, as
applicable, and provide such reasonable testimony and access to their books and
records as shall be necessary in connection with the contest or defense.

            6.7. Audits. Following the Closing, pursuant to Section 2.8, the
                 ------                                     -----------
Company's balance sheet as of the Closing Date will be prepared by the Company
and audited by AA at Empyrean Holdings' expense. To the extent that audited
financial statements of the Company for the fiscal years ended June 30, 1997 and
June 30, 1998 do not exist as of the Closing Date, Empyrean Holdings may, at its
expense, engage AA or another reputable independent accounting firm to audit
such financial statements. Stockholders, in their capacities as officers and
directors of the Company during such periods, shall provide all management
letters, reports or representations reasonably requested by such auditors in
connection with such audits and shall use their reasonable best efforts to
provide all necessary records in their possession to AA.

            6.8. Minimum Cash as of the Closing. At the Closing, the Company
                 ------------------------------
shall maintain a level of cash and cash equivalents equal to at least $100,000.
The Purchase Price payable at Closing will be reduced by the amount by which the
Company's cash and cash equivalents are less than $100,000 at Closing (the
"Minimum Cash Deficit"). In determining the Net Working Capital Adjustment, the
amount of Minimum Cash Deficit shall be added to the aggregate amount of any
downward Net Working Capital Adjustment (i.e., Net Working Capital is less than
$1,000,000) at Closing for purposes of determining the final Net Working Capital

                                      -31-
<PAGE>

Adjustment; provided, however, that in no event will a Minimum Cash Deficit
result in any upward Net Working Capital Adjustment.

            6.9. Empyrean Holdings' Stock Options. Not later than 30 days
                 --------------------------------
following the Closing Date, Empyrean Holdings will grant stock options to (i)
such persons who are employees of the Company as of the Closing Date and (ii)
persons to whom the Company has made (or makes within such 30-day period) an
offer of employment, as are mutually agreed upon by Empyrean Holdings and the
Majority Sellers. In the aggregate, all of such stock options will be
exercisable for an estimated 635,600 shares of Common Stock, with options for
approximately 600,000 shares reserved for employees of the Company as of the
Closing Date with the remainder to be granted to persons whose employment with
the Company commences following the Closing Date. The exercise price for such
stock options shall be at $.25 per share unless Majority Sellers and Buyer
mutually agree that such grants for such options shall be priced as incentive
stock options. The terms of such stock options shall generally be for ten years
from the date of grant, subject to customary four year annual vesting
requirements (i.e., 25% vesting per annum), and shall otherwise be on the same
terms and conditions applicable to all stock options granted to key executives
and employees of Empyrean Holdings and its subsidiaries.

            6.10. Replacement of Majority Sellers' Guaranties. At or promptly
                  -------------------------------------------
following the Closing, Empyrean Holdings will use its reasonable best efforts to
cause the Majority Sellers to be released as guarantors under all indebtedness,
letters of credit and leases of Invisions Group or the Company. Empyrean
Holdings will indemnify and hold harmless the Majority Sellers from the payment
of any guaranties on any indebtedness, letters of credit, leases or other
contractual obligations that the Majority Sellers had incurred prior to the
Closing Date provided that such indebtedness or obligations are related to the
Business and have been disclosed to Empyrean Holdings in writing prior to the
date hereof.

            8.1. Indemnification by Stockholders. Except as provided in Section
                 -------------------------------                        -------
8.6, Stockholders agree to jointly and severally indemnify and hold harmless
---
Empyrean Holdings and the Company and each officer, director, and Affiliate of
Empyrean Holdings and the Company, including without limitation any successor of
the Company that is an Affiliate of Empyrean Holdings and any of the Company's
or Emyrean Holdings' lenders as provided in Section 10.5 hereof (collectively,
                                            ------------
the "Indemnified Parties") from and against any and all damages, losses, claims,
liabilities, demands, charges, suits, penalties, costs and expenses (including
court costs and reasonable attorneys' fees and expenses incurred in
investigating and preparing for any litigation or proceeding) (collectively, the
"Indemnifiable Costs"), which any of the Indemnified Parties may sustain, or to
which any of the Indemnified Parties may be subjected, arising out of (A) any
misrepresentation, breach or default by Stockholders (as such, but severally and
not jointly in any other role, e.g., as an employee under any employment
agreement after the date hereof), Invisions Group or the Company of or under any
of the representations, covenants, agreements or other provisions of this
Agreement or any agreement or document executed in connection herewith;

Working Capital Adjustment not paid to the Company pursuant to a reduction of
the Escrow Sum; (C) cost of any brokerage or other transaction fees liability,

for consequential damages, to the extent not reserved for in the Company's
Financial Statements and (E) any failure of the Company to obtain any landlord
consents to the Acquisition contemplated hereby required under the terms of any

            8.2. Defense of Claims. If any legal proceeding shall be instituted,
                 -----------------
or any claim or demand made by a third Person, against any Indemnified Party in
respect of which Stockholders or Invisions Group may be liable hereunder, such
Indemnified Party shall give prompt written notice thereof to Stockholders and,
except as otherwise provided in Section 8.4 below, Stockholders shall have the
right to defend any litigation, action, suit, demand, or claim for which an
Indemnified Party may seek indemnifications, and such Indemnified Party shall
extend reasonable cooperation in connection with such defense, which shall be at
Stockholders' expense. In the event Stockholders fail or refuse to defend the
same within a reasonable length of time, the Indemnified Parties shall be
entitled to assume the defense thereof, and Stockholders shall be jointly and
severally liable to repay the Indemnified Parties for all reasonably incurred
Indemnifiable Costs. If Stockholders shall not have the right to assume the
defense of any litigation, action, suit, demand, or claim in accordance with the
preceding sentence, the Indemnified Parties shall, at Stockholders' expense,
have the absolute right to control the defense of such litigation, action, suit,
demand, or claim, but Stockholders shall be entitled, at their own expense, to
participate in such litigation, action, suit, demand, or claim. The party
controlling any defense pursuant to this Section 8.2 shall deliver, or cause to
                                         -----------
be delivered to the other party, copies of all correspondence, pleadings,
motions, briefs, appeals or other written statements relating to or submitted in
connection with the defense of any such litigation, action, suit, demand or
claim, and timely notice of any hearing or other court proceeding relating to
such litigation, action, suit, demand or claim. Notwithstanding the forgoing, in
no event will the party controlling any defense pursuant to this Section 8.2
                                                                 -----------
settle any litigation, action, suit, demand or claim without the prior written
consent of the non-controlling party, unless such settlement provides for the
unqualified, absolute and complete release of all claims against the
non-controlling party and results in no monetary or equitable liability to the
non-controlling party.

            8.3. Escrow Claim. If any claim for indemnification is made by an
                 ------------
Indemnified Party pursuant to this Article VIII prior to the expiration of the
                                   ------------

provided in Section 2.7 of this Agreement for reimbursement of such claim in
accordance with the provisions of the Escrow Agreement provided, however, to the

                    -----------
exclusive remedy in the event Empyrean Holdings or the Company has
indemnification claims hereunder which exceed such amount. Upon expiration of
the Escrow Period, all claims by Empyrean Holdings shall first be made against
the Seller Notes on a pro rata basis among all Stockholders. Empyrean Holdings,
in good faith, may elect to reduce the principal amount of the Seller Notes by
the amount of any Indemnifiable Costs or any other payments to which Empyrean
Holdings or such Indemnified Parties may become entitled by reason of the
provisions of this Agreement. In the event that such reductions by Empyrean
Holdings are greater than the amount of any Indemnifiable Costs (as finally
determined),

                                      -37-
<PAGE>

Empyrean Holdings shall be responsible to the Stockholders for such principal
amount that should not have been reduced, together with interest at the rate of
10% per annum.

            8.4. Tax Audits, Etc. In the event of an audit of a Tax Return of
                 ---------------
the Company or Invisions Group with respect to which an Indemnified Party might
be entitled to indemnification pursuant to this Article VIII, the Stockholders
                                                ------------
and the Company shall jointly control any and all such audits which may result
in the assessment of additional Taxes against the Company or Invisions Group and
any and all subsequent proceedings in connection therewith, including appeals.
Stockholders and Empyrean Holdings shall cooperate fully in all matters relating
to any such audit or other Tax proceeding (including according access to all
records pertaining thereto), and will execute and file any and all consents,
powers of attorney, and other documents as shall be reasonably necessary in
connection therewith. If additional Taxes are payable by the Company or
Invisions Group as a result of any such audit or other proceeding, Stockholders
shall be severally responsible for and shall promptly pay all Taxes, interest,
and penalties for which any of the Indemnified Parties shall be entitled to
indemnification.

                 -------------------------------
indemnify and hold harmless Stockholders, Invisions Group and the Company and
each officer, director, Stockholder or Affiliate of the Company, from and
against any Indemnifiable Costs arising out of any misrepresentation, breach or
default by Empyrean Holdings of or under any of the representations, covenants,
agreements or other provisions of this Agreement or any agreement or document
executed in connection herewith. Notwithstanding the foregoing, the liability of
Empyrean Holdings for any breaches of its representations and warranties
contained in Sections 4.10 through 4.15 of Article IV hereof shall be limited
             -------------         ----    ----------
to, in the case of breaches of such representations involving periods prior to
August 12, 1999, a proportionate share of any amounts paid to Thayer Itech
Holdings, LLC as a result of any similar breach of a corresponding
representation or warranty of BSG Holdings, Inc. and its shareholders pursuant
to the Recapitalization Agreement (and Thayer Itech Holdings, LLC shall have
provided a side letter to the Stockholders prior to the Closing that it will
assign a proportionate share of all such indemnification claim amounts to the
Stockholders). In addition, in determining the Indemnifiable Costs of
Stockholders for breaches by Empyrean Holdings for which indemnification is to
be provided by this Section 8.5, all losses shall be determined based on the
                    -----------
relative economic harm suffered by the Stockholders for such breach in
accordance with their relative economic ownership of Empyrean Holdings.

            8.6. Limits on Indemnification. All Indemnifiable Costs sought by
                 -------------------------
any party hereunder shall be net of any insurance proceeds received by such
Person with respect to such claim. Except for any claims for breach of the

hereof (the indemnification for which shall expire on the expiration of the
applicable statute of limitations or, in the case of covenants in Article VI
                                                                  ----------
which have a specific expiration date, as of such date, and if so made, such
claims, and all Indemnifiable Costs incurred thereafter, shall continue after
such date until finally resolved), the right of any party to make claims for

claims shall continue after such date until finally resolved). Empyrean Holdings

                                                                         -------

parties hereto shall first meet in good faith in order to attempt to resolve
such claim. In the event that the parties are unable to resolve such
indemnification claim within 30 days after written notice of such claim, the
parties agree to submit to arbitration, in accordance with these provisions, any
disputed claim or controversy arising from or related to the alleged breach of
this Agreement or any disputed indemnification claim made pursuant to this
Section VIII. The parties further agree that the arbitration process agreed upon
------------
herein shall be the exclusive means for resolving all disputes made subject to
arbitration herein, but that no arbitrator shall have authority to expand the
scope of these arbitration provisions. Any arbitration hereunder shall be
conducted under the commercial arbitration rules of the American Arbitration
Association (AAA). Either party may invoke arbitration procedures herein by
written notice for arbitration containing a statement of the matter to be
arbitrated. The parties shall then have fourteen (14) days in which they may
identify a mutually agreeable, neutral arbitrator. After the fourteen (14) day
period has expired, the parties shall prepare and submit to the AAA a joint
submission, with each party to contribute half of the appropriate administrative
fee. In the event the parties

                                      -39-
<PAGE>

cannot agree upon a neutral arbitrator within fourteen (14) days after written
notice for arbitration is received, their joint submission to the AAA shall
request arbitrators who are practicing attorneys with professional experience in
the field of corporate law, and the parties shall attempt to select an
arbitrator from the panel according to AAA procedures; provided, however, that
in the event the parties cannot agree, the AAA shall appoint an arbitrator.
Unless otherwise agreed by the parties, the arbitration hearing shall take place
in the Washington, D.C. metropolitan area, at a place designated by the AAA. All
arbitration procedures hereunder shall be confidential. Each party shall be
responsible for its costs incurred in any arbitration, and the arbitrator shall
not have authority to include all or any portion of said costs in an award
regardless of which party prevails. The arbitrator may include equitable relief.
The decision of the arbitrator shall be rendered not later than 30 days
following the hearing. Any arbitration awarded shall be accompanied by a written

Stockholder Subscription Agreement. Each certificate for Common Stock, Preferred
Stock or Seller Notes shall be imprinted with a customary securities legend in a
form provided by Empyrean Holdings' counsel.
