ITEM 2.   OTHER EVENTS.

       On March 31, 2000, FastComm Communications Corporation, a Virginia
corporation ("FastComm") completed its acquisition of substantially all of the
assets of Cronus Technology, Inc. a privately held Illinois corporation that
provides system interoperability solutions to the telecommunications industry
("Cronus"). The acquisition was effected pursuant to an Agreement and Plan of
Reorganization executed by FastComm, Cronus, Cronus Communications, Inc. and
certain principal stockholders of Cronus, dated as of March 27, 1999 (the
"Acquisition Agreement").

       In the acquisition, FastComm issued 3,700,000 shares of its common stock
(the "Acquisition Price") in exchange for substantially all of the assets of
Cronus and the assumption of certain liabilities of Cronus, including certain
secured indebtedness, management and bank debt. At Closing, indebtedness of
certain former owners of Cronus, management debt and subordinated debt was
retired in consideration of

the issuance of an additional 728,063 restricted shares of FastComm stock, the
payment of cash, and the issuance of warrants to purchase shares of FastComm
stock.

        Under the terms of the Acquisition Agreement, a further adjustment will
be made to the Acquisition Price if the closing price of FastComm's common
stock on the Nasdaq Stock Market for the 15 trading day period ended March 31,
2001 (the "First Anniversary") does not equal or exceed $7.30 per share. In
such event up to 1,125,000 additional shares of FastComm common stock will be
issued such that the value of the Acquisition Price is as close as possible to
$27 million based upon that average closing price. The foregoing collar will be
null and void (a) if at any time prior to the First Anniversary of the Closing
and after the shares have been registered by FastComm, FastComm's common stock
share price closes at $7.30 per share or above for five consecutive trading
days or (b) if the average closing price for the shares is above $7.30 per
share for the fifteen days prior to the First Anniversary. In addition, the
Acquisition Agreement provides for an adjustment in the Acquisition Price if
the audited net worth of Cronus varies by 5% or more from the unaudited net
worth of Cronus at December 31, 1999.

       The Acquisition constituted a tax-free reorganization.

consideration for the purchase of the Purchased Assets and the assumption of the
Assumed Liabilities ("Purchase Price");

                     (i)    3,700,000 shares of the common stock of Buyer (the
"Shares") and on the First Anniversary of the Closing (the "First Anniversary")
up to a maximum of 1,125,000 additional shares ("Collar") so as to bring the
total value of this paragraph as close as possible to




                                       8
<PAGE>   14

$27 million valued according to the average closing price for the fifteen (15)
days prior to the First Anniversary; provided however, (a) if at any time prior
to the First Anniversary of the Closing and after the Shares have been
registered by Buyer, Buyer's common stock share price closes at $7.30 per share
or above for five consecutive trading days, or (b) if the average closing price
for the Shares is above $7.30 per share for the fifteen days prior to the First
Anniversary, the foregoing Collar will be null and void.

                     (b)    None of the Shares of Buyer contained in Section 2.5
above will be registered at Closing. Buyer will file for registration of all of
the shares contained in Section 2.5 within 45 days of filing of Buyer's Annual

efforts to secure an effective registration as soon as practicable thereafter.
If such registration statement is not filed within such time period absent force
majeure, Buyer shall pay liquidated damages of $100,000 to Seller. Such
registration may in the Buyer's discretion, be combined with other
registrations.

                     2.6    POST-CLOSING ADJUSTMENT TO PURCHASE PRICE.

                     (a)    Following the Closing, Buyer's independent public
accountants, BDO Seidman, LLP ("BDO") will complete an audit of the books and
records of Seller for the two fiscal years ending December 31, 1998 and December
31, 1999 and a review for the interim period from the December 31, 1999 to the
Closing Date. Such audit shall be performed by BDO in accordance with GAAP and
applicable Regulation S-X accounting regulations for public companies. Seller
agrees to cause its employees and outside accountants to cooperate fully with
BDO in connection with this audit. The costs of this audit shall be borne by
Buyer.

                            In connection with the performance of its audit,
which audit shall be completed within approximately 75 days after the Closing,
BDO shall prepare and submit an audited closing balance sheet as at December 31,
1999 ("Closing Balance Sheet") which shall be irrevocably binding on the
parties, absent manifest error. If the Net Worth as shown on such Closing
Balance Sheet is 5% higher or lower than the Net Worth shown on the unaudited
Balance Sheet, as herein after defined in Section 3.5 then the Purchase Price
shall be adjusted accordingly. The increase or decrease to the Purchase Price
shall be determined by dividing the total adjustment (the "Adjustment Amount")
by $7.30 to determine the increase or decrease in


                                       9
<PAGE>   15

the number of shares to be delivered to Seller from the escrow described in
Section 2.6(b) and Article V below. If this Agreement has been executed by the
parties by close of business on March 27, 2000, the Adjustment Amount shall be
increased by $400,000. If the Agreement has not been executed by close of
business on March 27, 2000, the amount of such increase shall be reduced by
$100,000 per day thereafter to and through March 31, 2000.

              (b)    At Closing 55% of the 3,700,000 shares listed in Section
2.5(a) of the Agreement shall be issued to Seller and delivered to the Escrow
Agent, as hereinafter defined, to be issued to Seller's Stockholders and the
Significant Minority Stockholder (in such ratios and numbers as the Seller's
Stockholders and the Significant Minority Stockholder may instruct the Escrow
Agent by separate writing) and 30% of such shares shall be held in escrow
pursuant to the terms and conditions of Article V, pending completion of the
adjustment described in 2.6(a) above. An additional 15% of the shares shall be
held in escrow for a period of 180 days after the Closing as security for the
indemnities and other covenants of Seller to be given at Closing, including the
indemnity referenced in Article IX hereof.

              2.7    CLOSING. The closing of the sale referred to in Section 2.1
(the "Closing") shall take place at the offices of the Buyer, 45472 Holiday
Drive, Dulles, Virginia at 9:00 A.M. on March 31, 2000 or at such earlier time
and date following the satisfaction or waiver of the conditions precedent set
forth in Article VIII of this Agreement as the parties hereto may mutually
agree. Such date is herein referred to as the "Closing Date."

              2.8    NONTRANSFERABILITY. The parties intend that all of the
agreements set forth in Schedule 2.1(b) hereto be assigned to and assumed by
Buyer. To the extent that the transactions contemplated hereby would constitute
the assignment of any contract, lease, commitment, sales order, purchase order,
account, license or undertaking of Seller or any of its Affiliates requiring the
consent of another party thereto, this Agreement shall not constitute an
agreement to assign the same if an attempted assignment would constitute a
breach thereof. If such consents are not obtained, the parties shall cooperate
with each other (at Buyer's expense and so long as Seller and its Affiliates
shall not incur any unreimbursed liability or obligation of



                                       10
<PAGE>   16

any type) to establish lawful arrangements whereby Buyer is provided with the
benefits and undertakes the obligations of Seller or its Affiliates under any
such documents.

              2.9    ALLOCATION OF PURCHASE PRICE. Sellers and Buyers agree to

purports to own, except for such failures of title as will not have a Material
Adverse Effect.

              (e)    To the extent that any material Intellectual Property has
been developed or created by a third party for Seller, Seller has a written
agreement with such third party with respect thereto and Seller thereby either
(i) has obtained ownership of, and is the exclusive owner of or (ii) has
obtained a license (sufficient for the conduct of its business as currently
conducted and as proposed to be conducted) to all such third party's
Intellectual Property in such Intellectual Property by operation of law or by
valid assignment.

transferred ownership of or granted any exclusive distribution rights or
exclusive license with respect to, any Intellectual Property that is or was
Seller Intellectual Property, to any third party.

              (g)    Sellers Schedules list all material contracts, licenses and
agreements to which Seller is a party (i) with respect to Seller Intellectual
Property licensed or transferred to any third party (other than end-user
licenses in the ordinary course); or (ii) pursuant to which a third party has
licensed or transferred any Intellectual Property to Seller.

              (h)    All material contracts, licenses and agreements relating to
Seller Intellectual Property are in full force and effect. Seller is in material
compliance with, and has not materially breached any term any of such contracts,
licenses and agreements and, to the knowledge of Seller, all other parties to
such contracts, licenses and agreements are in compliance with, and have not
materially breached any term of such contracts, licenses and agreements. Except
as set forth in Schedule 3.4 or 3.11, following the Closing Date, the Buyer will
be permitted to exercise all of Seller's rights under such contracts, licenses
and agreements to the same extent Seller would have been able to had the
transactions contemplated by this Agreement not occurred and without the payment
of any additional amounts or consideration other than ongoing fees, royalties or
payments which Seller would otherwise be required to pay

              (i)    The operation of the Business of Seller as such business
currently is conducted, including Seller's design, development, manufacture,
marketing and sale of the products or services of Seller (including with respect
to products currently under development) has not, does not and will not infringe
or misappropriate the Intellectual Property of any third party (provided that
with respect to patent rights, such representation is limited to Seller's
knowledge), except for any infringement or misappropriation that will not have a
Material Adverse Effect or, to its knowledge, constitute unfair competition or
trade practices under the laws of any jurisdiction.

              (j)    Seller has not received notice from any third party that
the



                                       23
<PAGE>   29

operation of the business of Seller or any act, product or service of Seller,
infringes or misappropriates the Intellectual Property of any third party or
constitutes unfair competition or trade practices under the laws of any
jurisdiction.

              (k)    Except as set forth in Schedule 3.11(k), to the Knowledge
of Seller, no Person has or is infringing or misappropriating any Seller
Intellectual Property.

              (l)    Seller has taken reasonable steps to protect Seller's
rights in Seller's confidential information and trade secrets that it wishes to
protect or any trade secrets or confidential information of third parties
provided to Seller.

              (m)    YEAR 2000. To the knowledge of Seller, Seller's computer
software, hardware, databases and/or embedded control systems (collectively, a
"System") are and will continue to be Year 2000 Compliant. As used herein, "YEAR
2000 COMPLIANT" means that each System (i) is designed (or has been modified) to
be used prior to, on and after January 1, 2000, (ii) operate without error
arising from the creation, recognition, acceptance, calculation, display,
storage, retrieval, accessing, comparison, sorting, manipulation, processing or
other use of dates or date-based, date-dependent or date-related data,
including, but not limited to, century recognition, day-of-the-week recognition,
leap years, date values and interfaces of date functionalities; and (iii) are
not adversely affected by the advent of the year 2000, the advent of the
twenty-first century or the transition from the twentieth century through the
year 2000 and into the twenty-first century. Seller has no reason to believe
that the operation of Seller's business as currently operated will result in the
incurrence of material expenses arising from or relating to the failure of any
of its Systems to be Year 2000 Compliant. To the Knowledge of Seller, all goods
and services utilizing computer software and related systems that Seller
receives from third parties are Year 2000 Compliant.

                     property" within the meaning of Section 168(h) of the Code.

                     (x) As of the Closing Date, Buyer will not be a party to
                     any contract, agreement, plan or arrangement, including but
                     not limited to the provisions of this Agreement, covering
                     any employee or former employee of Buyer that could
                     obligate Buyer to pay any amount that would not be
                     deductible pursuant to Section 280G of the Code.

                     (xi) Buyer has not filed any consent agreement under
                     Section 341(f) of the Code nor agreed to have Section 341
                     (f)(2) of the Code apply to any disposition of a subsection
                     (f) asset (as defined in Section 341(f)(4) of the Code)
                     owned by Buyer.

                     (xii) Buyer is not a party to a tax sharing or allocation
                     agreement nor does Buyer owe any amount under any such
                     agreement.

                     (xiii) Buyer is not, and has not been at any time, a
                     "United States real property holding corporation" within
                     the meaning of Section 897(C)(2) of the Code.

                     (xiv) Buyer's tax basis in its assets for purposes of
                     determining its future amortization, depreciation and other
                     federal income tax deductions is accurately reflected on
                     Buyer's tax books and records in all material respects.

       4.10   RESTRICTIONS OF BUSINESS ACTIVITIES There is no agreement
(non-compete or otherwise), commitment, judgment, injunction, order or decree to
which Buyer is a party or otherwise binding upon Buyer which has or reasonably
could be expected to have the effect of materially impairing or prohibiting any
lawful business practice of Buyer, any acquisition of property (tangible or
intangible) by Buyer or the conduct of business by Buyer as presently conducted.

                                    ARTICLE V

               SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ESCROW

            5.1  SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The
representations and warranties in this Agreement or in any
instrument delivered pursuant to this Agreement shall survive
the Closing and continue until September 30, 2001.

            5.2  STOCKHOLDER ESCROW ARRANGEMENTS.

       (a) ESCROW FUNDS. As provided in Section 2.6(b), at the Closing , the
45% of the Buyers Common Stock to be issued to Seller ("Escrow Amount") will be
deposited into an escrow account with Tighe, Patton & Babbin, P.L.L.C. (the
"ESCROW AGENT"), such deposit to constitute an escrow fund (the "ESCROW FUND").
The terms upon which the Escrow Agent will serve in such capacity shall be as
provided in an Escrow Agreement to be mutually agreed upon by Buyer and Seller,
and which will be consistent with the provisions of Section 2.6 and of this
Article V (the "ESCROW AGREEMENT"). The Escrow Fund is to be governed by the
terms set forth in the Escrow Agreement and maintained at Buyer's sole cost and
expense (the "STOCKHOLDER ESCROW"). The portion of the Escrow Amount contributed
on behalf of each of Seller's Stockholders shall correspond to such
Stockholder's Proportionate Escrow Interest.

       (b) PURPOSE. (i) That portion of the Escrow  Fund referenced in
section 2.6(b) relating to Post Closing adjustments to the Purchase Price
(herein the "Adjustment Portion") shall be utilized for such purpose; and (ii)
the balance of the Escrow Fund shall be available to compensate Buyer and its
affiliates for any claim, loss, expense, liability or other damage, including
reasonable attorneys' fees, to the extent of the amount of such claim, loss,
expense, liability or other damage (collectively "LOSSES") that Buyer or any of
its affiliates has incurred or reasonably anticipates incurring (in the case of
an extension of the Stockholder Escrow period pursuant to Section 5.2(c)) by
reason of the breach by Seller or Principal Stockholders of any representation,
warranty, covenant or agreement of Seller
or Principal


                                       48
<PAGE>   54
Stockholders contained herein, including the indemnities provided
for in Section 9.1(a) hereof and the covenants contained in Section 6.2 hereof.
Losses shall not include amounts recovered from insurance. Buyer shall
undertake commercially reasonable efforts to claim and collect insurance to
which it is entitled with respect to any Losses.

       (c) TERMINATION AND DISTRIBUTION OF ESCROW FUND.  On or about June 15,
2000, the Escrow shall terminate as to the Adjustment Portion and on such date
the Escrow Agent shall distribute the Adjustment Portion of the Escrow Fund to
the Seller or Buyer, as the case may be, all in accordance with Section 2.6
hereof. The Escrow as to the balance of the Escrow Fund shall terminate on
September 30, 2000. PROVIDED HOWEVER, that such portion of the Stockholder
Escrow, which, in the reasonable judgment of Buyer, subject to the objection of
the Seller Stockholder Agent and the subsequent arbitration of the matter in the
manner provided in Section 5.2(i) hereof, is necessary to satisfy any identified
but unsatisfied Losses specified in any Officer's Certificate theretofore
delivered to the Escrow Agent prior to termination of the Stockholder Escrow,
shall remain in the Stockholder Escrow (and the Stockholder Escrow shall remain
in existence) until the earlier of (i) the expiration of the statute of
limitations applicable to such claims or (ii) the resolution of such claims. As
soon as all such claims have been resolved or the statute of limitations has
expired, the Escrow Agent shall deliver to the appropriate security holders of
Seller the remaining portion of the Stockholder Escrow not required to satisfy
such claims. Deliveries of Escrow Amounts to the Seller's stockholders pursuant
to this Section 5.2(c) shall be made according to each stockholder's
Proportionate Escrow Interest as certified to the Escrow Agent by the Seller
Stockholder Agent.

       (d) PROTECTION OF ESCROW FUND.  The Escrow Agent shall hold and
safeguard the Escrow Funds during their existence, shall treat such fund as a
trust fund in accordance with the terms of this Agreement and not as the
property of Buyer and shall hold and dispose of the Escrow Funds only in
accordance with the terms hereof.

       (e) CLAIMS UPON ESCROW FUND. In the event Buyer incurs or becomes aware
of any Losses or potential Losses for which it is entitled to indemnity under
Article IX and this Article V, it shall deliver to the Escrow Agent and the
Seller Stockholder




                                       49
<PAGE>   55
Agent a certificate signed by any officer of Buyer (an "OFFICER'S CERTIFICATE")
(A) stating that Buyer has (i) incurred or (ii) for purposes of extending the
Escrow pursuant to Section 5.2(c above, reasonably anticipates that it will
have to incur Losses, (B) specifying in reasonable detail the individual items
of Losses included in the amount so stated, the date each such item was paid or
properly incurred, or the basis for such anticipated liability, and either the
nature of the misrepresentation, breach of warranty or claim or the litigation
matter to which such item is related. Upon the receipt of a certificate pursuant
to clause (A)(i) above and after compliance with the provisions of Sections
5.2(f), (g) and (h) hereof, and if there is no written objection by Seller as
further provided in subsection (g) hereof, the Escrow Agent shall deliver to
Buyer out of the Escrow Fund, as promptly as practicable, such amounts held in
the Escrow Fund equal to such Losses incurred. In determining the number of
shares of Buyer Common Stock to be paid out by the Escrow Agent pursuant to this
Article V, such shares shall be valued by the Escrow Agent at the value of $7.30
per share.

       (f) Buyer shall not be entitled to receive any disbursement or cause any
amount to be retained in Escrow with respect to any Losses arising in respect
of any individual occurrence or circumstance unless the aggregate amount of all
Losses shall exceed $10,000; provided that in the event the aggregate amount of
such Losses of Buyer shall exceed $10,000, then Buyer shall be entitled to
recover from the Escrow Fund only Losses in excess of $10,000.

       (g) OBJECTIONS TO CLAIMS.   At the time of delivery of any Officer's
Certificate to the Escrow Agent, a duplicate copy of such certificate shall be
delivered to the Seller Stockholder Agent (as defined in Section 5.2(i)). The
Escrow Agent shall make no delivery to Buyer of any amounts out of the Escrow
Fund, pursuant to Section 5.2(e)(A)(i) hereof, unless and until the Escrow
Agent shall have received written authorization from the Seller Stockholder
Agent to make such delivery or unless the claim shall have been resolved
pursuant to Section 5.2(h). If the Seller Stockholder Agent shall object to the
claim made in the Officer's Certificate, the Seller Stockholder Agent shall do
so in a written statement to such effect delivered to the Escrow Agent. The
Seller Stockholder Agent shall approve or object to any such claim within a
reasonable time after actual receipt of the Officer's Certificate.

<PAGE>   56

                 (h) RESOLUTION OF CONFLICTS; ARBITRATION.
                     (i) In case the Seller Stockholder Agent shall so object in
                     writing to any claim or claims made in any Officer's
                     Certificate, the Seller Stockholder Agent and Buyer shall
                     attempt in good faith to agree upon the rights of the
                     respective parties with respect to each of such claims. If
                     the Seller Stockholder Agent and Buyer should so agree, a
                     memorandum setting forth such agreement shall be prepared
                     and signed by both parties and shall be furnished to the
                     Escrow Agent.  The Escrow Agent shall be entitled to rely
                     on any such memorandum and distribute amounts from the
                     Escrow Funds in accordance with the terms thereof.

                     (ii) If no such agreement can be reached after good faith
                     negotiation, the matter shall be arbitrated before the
                     American Arbitration Association. Either Buyer or the
                     Seller Stockholder Agent may demand arbitration of the
                     matter unless the amount of the damage or loss is at issue
                     in pending litigation with a third party, in which event
                     arbitration shall not be commenced until such amount is
                     ascertained upon the conclusion of such litigation or both
                     parties agree to arbitration, and in either such event the
                     matter shall be settled by binding arbitration conducted by
                     three arbitrators. Buyer and the Seller Stockholder Agent
                     shall each select one arbitrator, and the two arbitrators
                     so selected shall select a third arbitrator. The
                     arbitrators shall set a limited time period and establish
                     procedures designed to reduce the cost and time for
                     discovery while allowing the parties an opportunity,
                     adequate in the sole judgment of the arbitrators, to
                     discover relevant information from the opposing parties
                     about the subject matter of the dispute. The arbitrators
                     shall rule upon motions to compel or limit discovery and
                     shall have the authority to impose sanctions, including
                     attorneys' fees and costs, to the same extent as a court
                     of competent law or equity, should the arbitrators
                     determine that discovery was sought without substantial
                     justification or that discovery was refused or objected to

                                       51
<PAGE>   57

                     without substantial justification. The decision of the
                     arbitrators as to the validity and amount of any claim in
                     such Officer's Certificate shall be binding and conclusive
                     upon the parties to this Agreement, and notwithstanding
                     anything in this Section 5.2(h); the Escrow Agent shall be
                     entitled to act in accordance with such decision and make
                     or withhold payments out of the Escrow Fund in accordance
                     therewith. Such decision shall be written and shall be
                     supported by written findings of fact and conclusions of
                     law, which shall set forth the award, decree or order of
                     the arbitrators.

                     (iii) Judgment upon any award rendered by the arbitrators
                     may be entered in any court having jurisdiction. Any such
                     arbitration shall be held in either Washington, D.C. or
                     Richmond, Virginia, under the rules then in effect of the
                     American Arbitration Association.

                 (i) AGENT OF SELLER'S STOCKHOLDERS; POWER OF ATTORNEY. (i)
                     Upon execution and delivery of this Agreement, without
                     further act of any stockholder of Seller, William J. Dawson
                     shall be appointed as agent and attorney-in-fact (the
                     "SELLER STOCKHOLDER AGENT") for each stockholder of Seller
                     on whose behalf any Buyer Common Stock was deposited into
                     the Escrow Fund for and on behalf of stockholders of
                     Seller, to give and receive notices and communications, to
                     authorize delivery to Buyer of Buyer Common Stock from the
                     Escrow Fund in satisfaction of claims by Buyer, to object
                     to such deliveries, to agree to, negotiate, enter into
                     settlements and compromises of, and demand arbitration and
                     comply with orders of courts and awards of arbitrators
                     with respect to such claims, and to take all actions
                     necessary or appropriate in the judgment of the Seller
                     Stockholder Agent for the accomplishment of the foregoing.
                     Such agency may be changed by the stockholders of Seller
                     from time to time upon not less than thirty (30) days prior
                     written notice to Buyer; provided that the Seller
                     Stockholder Agent may not be removed


                                       52
<PAGE>   58
                     unless holders of a two-thirds interest of the Escrow
                     Funds agree to such removal and to the identity of the
                     substituted agent. No bond shall be required of the Seller
                     Stockholder Agent, and the Seller Stockholder Agent shall
                     not receive compensation for his services. Notices or
                     communications to or from the Seller Stockholder Agent
                     shall constitute notice to or from each of the stockholders
                     of Seller.

                     (ii) The Seller Stockholder Agent shall not be liable for
                     any act done or omitted hereunder as Agent while acting in
                     good faith and in the exercise of reasonable judgment. The
                     stockholders of Seller on whose behalf the amounts were
                     contributed to the Escrow Funds shall severally indemnify
                     the Seller Stockholder Agent and hold the Seller
                     Stockholder Agent harmless against any loss, liability or
                     expense incurred without negligence or bad faith on the
                     part of the Seller Stockholder Agent and arising out of or
                     in connection with the acceptance or administration of the
                     Seller Stockholder Agent's duties hereunder, including the
                     reasonable fees and expenses of any legal counsel retained
                     by the Seller Stockholder Agent.

       (j) ACTIONS OF THE SELLER'S STOCKHOLDER AGENT. A decision, act, consent
or instruction of the Seller Stockholder Agent shall constitute a decision of
all the stockholders for whom a portion of the amounts otherwise issuable to
them are deposited in the Escrow Funds and shall be final, binding and
conclusive upon each of such stockholders, and the Escrow Agent and Buyer may
rely upon any such decision, act, consent or instruction of the Seller's
Stockholder Agent as being the decision, act, consent or instruction of each and
every such stockholder of Seller. The Escrow Agent and Buyer are hereby relieved
from any liability to any person for any acts done by them in accordance with
such decision, act, consent or instruction of the Seller Stockholder Agent.

<PAGE>   59




                 (k) THIRD-PARTY CLAIMS. If during The Escrow
            Period, a third-party asserts a claim which gives rise to a
            claim to The Escrow supported by an Officer's Certificate,
            Buyer shall have the right in its sole discretion to defend and to
            settle such third-party claim, provided, however, that any counsel
            retained to defend a third-party claim to be satisfied from the
            Escrow Fund shall be reasonably acceptable to the Seller Stockholder
            Agent and Buyer shall not settle any such third party claim without
            the prior consent of the Seller Stockholder Agent, which consent
            shall not be unreasonably withheld.

            5.3  ESCROW AGENT'S DUTIES.
                 (a) The Escrow Agent shall be obligated only for the
performance of such duties as are specifically set forth herein, and as set
forth in any additional written escrow instructions which the Escrow Agent may
receive after the date of this Agreement which are signed by an officer of Buyer
and the Seller Stockholder Agent, and may rely and shall be protected in relying
or refraining from acting on any instrument reasonably believed to be genuine
and to have been signed or presented by the proper party or parties. The Escrow
Agent shall not be liable for any act done or omitted hereunder as Escrow Agent
while acting in good faith and in the exercise of reasonable judgment, and any
act done or omitted pursuant to the advice of counsel shall be conclusive
evidence of such good faith.

                 (b) The Escrow Agent is hereby expressly authorized to
disregard any and all warnings given by any of the parties hereto or by any
other person, excepting only orders or process of courts of law, and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of
any court. In case the Escrow Agent obeys or complies with any such order,
judgment or decree of any court, the Escrow Agent shall not be liable to any of
the parties hereto or to any other person by reason of such compliance,
notwithstanding any such order, judgment or decree being subsequently reversed,
modified, annulled, set aside, vacated or found to have been entered without
jurisdiction.

                 (c) The Escrow Agent shall not be liable in any respect on
account of the



                                       54
<PAGE>   60
rights of the parties executing or delivering or purporting to execute or
deliver this Agreement or any documents or papers deposited or called for
hereunder.

                 (d) The Escrow Agent shall not be liable for the expiration of
any rights under any statute of limitations with respect to this Agreement or
any documents deposited with the Escrow Agent.

                 (e) The Escrow Agent may resign at any time upon giving at
least thirty (30) days written notice to Buyer and the Seller Stockholder Agent
to this Agreement; PROVIDED, HOWEVER, that no such resignation shall become
effective until the appointment of a successor escrow agent which shall be
accomplished as follows: Buyer and the Seller Stockholder Agent shall use their
best efforts to mutually agree upon a successor agent within thirty (30) days
after receiving such notice. If the parties fail to agree upon a successor
escrow agent within such time, Buyer shall have the right to appoint a
successor escrow agent. The successor escrow agent selected in the preceding
manner shall execute and deliver an instrument accepting such appointment and
it shall thereupon be deemed the Escrow Agent hereunder and it shall without
further acts be vested with all the estates, properties, rights, powers, and
duties of the predecessor Escrow Agent as if originally named as Escrow Agent.
Thereafter, the predecessor Escrow Agent shall be discharged from any further
duties and liabilities under this Agreement.

            5.4    LIMITATION ON LIABILITY.  Notwithstanding any other
provision of this Agreement to the contrary, absent fraud or bad faith, the
liability of Seller and the Principal Stockholders with respect to any claim
for a breach of any representation, warranty, covenant or agreement contained
in this Agreement shall be limited to the assets of the Escrow Fund, and no
Principal Stockholder or significant Minority Stockholder shall have any
liability to Buyer or arising from any breach after the termination of the
Escrow other than with respect to claims made prior to such termination under
Section 5.2(c) (and liability with such claims shall be limited to the amount
held in the Escrow as a result thereof).

                                   ARTICLE VI
                              PRE-CLOSING COVENANTS

            Each of the Buyer and Seller agrees as follows with respect to the
period from and after the execution of this Agreement through and including the
Closing Date:

            6.1 GENERAL. Each of the Seller and Buyer will use all reasonable
efforts to take all actions and to do all things necessary in order to
consummate and make effective the transactions contemplated by this Agreement
(including satisfaction, but not waiver, of the closing conditions set forth in
Article VII below). In addition, as promptly as practicable after signing this
Agreement, Buyer and Seller shall retain the Escrow Agent and negotiate and
enter into an Escrow Agreement.

            6.2 OPERATION OF SELLER'S BUSINESS.  During the period from the
date of this Agreement to the Closing Date, Seller agrees to use its reasonable
best efforts to maintain, and to cause its Subsidiary and Affiliates to
maintain, all rights to the Intellectual Property listed on Schedule 3.11(a)
and the goodwill of the Cronus Business. Seller will not, without the written
consent of Buyer, take any action or enter into any transaction other than in
the ordinary course of business consistent with past practice. Without limiting
the generality of the foregoing, except as expressly provided in this Agreement
without the written consent of Buyer, Seller will not:

                     (i) authorize or effect any change in its charter or by-
                     laws or comparable organizational document;

                     Cronus Business.

                     In the event Seller shall request Buyer to consent in
                     writing to an action otherwise prohibited by this Section
                     6.2, Buyer shall use reasonable efforts to respond in a
                     prompt and timely fashion (but in no event later than ten
                     (10) business days following such request), but may
                     otherwise respond affirmatively or negatively in its sole
                     discretion.

            6.3 ACCESS. Seller will permit representatives of Buyer to have
access at all reasonable times and in a manner so as not to materially
interfere with the normal business operations of Seller and Subsidiary, to all
premises, properties, personnel, books, records (including without limitation
tax and financial records), contracts and documents of or pertaining Seller.
Buyer and all of its representatives will treat and hold as such any
confidential information it receives from Seller or any of its representatives.

            6.4 NOTICE OF DEVELOPMENTS. Seller will give prompt written notice
to Buyer of any material adverse development causing a breach of any of its own
representations and warranties in Article III above. No disclosure by Seller
pursuant to this Section 6.4, however, shall be deemed to amend or supplement
Seller Schedules or to prevent or cure any misrepresentation, breach of
warranty or breach of covenant.

            6.5 EXCLUSIVE DEALING.
                (a)  Seller shall immediately cease and terminate any
existing solicitation, initiation, encouragement, activity, discussion or
negotiation with any Persons conducted heretofore by Seller, its officers,
directors, employees, financial advisors, stockholders, agents or
representatives (each a "REPRESENTATIVE") with respect to any proposed,
potential or contemplated proposal or offer (including, without limitation, any
proposal or offer to the Seller Stockholders) with respect to a merger,
acquisition, sale, consolidation, recapitalization, reorganization, liquidation,
tender offer, or exchange offer or similar transaction involving, or any
purchase of 25% or more of the consolidated assets of, or any equity interest
representing


                                       59
<PAGE>   65
25% or more of the outstanding shares of capital stock in, Seller
(an "ACQUISITION PROPOSAL").

                (b)  From and after the date hereof, without the prior written
consent of Buyer, Seller shall cause any and all of its Representatives not to,
directly or indirectly, (A) solicit, initiate, or encourage any inquiries or
proposals that constitute, or could reasonably be expected to lead to, an
Acquisition Proposal, or (B) engage in negotiations or discussions with any
third party concerning, or provide any non-public information to any person or
entity relating to, an Acquisition Proposal, or (C) enter into any letter of
intent, agreement in principle or any acquisition agreement or other similar
agreement with respect to any Acquisition Proposal.

                (c)  Seller shall notify Buyer promptly after receipt by Seller
or Seller's knowledge of the receipt by any of its Representatives of any
Acquisition Proposal or any request for non-public information in connection
with an Acquisition Proposal or for access to the properties, books or records
of Seller by any Person that informs such party that it is considering making
or has made an Acquisition Proposal. Such notice shall be made orally and in
writing and shall indicate the identity of the offeror and the terms and
conditions of such proposal, inquiry or contact. Seller shall keep Buyer
informed of the status (including any change to the material terms) of any such
Acquisition Proposal or request for non-public information.

                (d)  Seller agrees with Buyer that any breach of this
Section 6.5 could not be compensated with monetary damages alone and that
without in any way limiting Buyer's rights, Buyer shall be entitled to
injunctive or other equitable relief against any breach or threatened breach of
this Section 6.5. In the event of a breach by Seller of this Section 6.5 then
Seller shall pay, within ten days of such breach, to Buyer an amount equal to
the greater of (1) the amount of professional fees and out-of-pocket expenses
incurred by Buyer in the connection with this proposed transaction and (2)
$250,000.

conditions set forth herein as to price shall have been publicly announced or

not been irrevocably withdrawn prior to the end of the Exclusivity Period, then

with the transaction to be approved for listing on Nasdaq Smallcap Market,

Common Stock.

            6.8 BULK TRANSFER LAWS. Buyer hereby waives compliance with the

with the transactions contemplated by this Agreement. Buyer shall indemnify and
hold harmless each Seller Indemnitee against any and all liabilities that may be
asserted by third parties against such Seller Indemnitee as a result of
noncompliance by Seller with any such bulk transfer law.

affiliates and the successors to the foregoing, hereby indemnify and hold the
Buyer and its officers, directors, and affiliates, harmless on an after-Tax
basis for (i) all Taxes relating to the income, operations, or assets of Seller
imposed on the Buyer and its affiliates for all Pre-Closing Periods; (ii) all
Taxes imposed on the Seller or any corporation in which the Seller or its
affiliates have a direct or indirect equity interest for any taxable year or
period; and (iii) all Taxes resulting from, arising out of, or incurred with
respect o, any claims that may be asserted by any party based upon,
attributable to, or resulting from any breach by the Seller of the
representations set forth in this Agreement.

                   (c) Buyer agrees to indemnify Seller, its Affiliates
and their respective directors, officers, employees, agents and representative
(each a "Seller Indemnitee") against, and hold each Seller Indemnitee harmless
from, any and all Damages (such Damages to be calculated taking into account any
reduction in Taxes or any other Tax benefit to such Seller Indemnitee resulting
from or received as a result of the incurrence of such Damages including
reasonable attorney's fees and disbursements, interest and penalties), whether
or not resulting from third party claims, which the Seller Indemnitee may
sustain at any time by reason of or resulting from (i) the inaccuracy of any of
the representations or warranties of Buyer contained in Article IV hereof or
(ii) Buyer's failure after the Closing Date to pay, discharge or perform and of
the Assumed Liabilities when due.

                   (d) If any Indemnitee shall incur any Damages and believes
that it is entitled to be indemnified against such Damages by Seller or Buyer,
as the case may be, such Indemnitee shall promptly notify such party in
reasonable detail of the basis of such Damages and such claim for
indemnification hereunder.

                        (e) Each party's obligations pursuant to this Section
9.1 are subject to the following further limitations.

                               (i) the Buyer Indemnitees shall not be entitled
              to recover hereunder until the total amount of Damages, exclusive
              of attorneys fees exceeds $10,000; provided that to the extent the
              amount of Damages exceed such amount the Buyer Indemnitees shall
              be entitled to recover only the amount of Damages in excess of
              $10,000;

                               (ii) the Seller Indemnitees shall not be
              entitled to recover hereunder until the total amount of Damages,

be satisfied out of the Escrow Fund.

                        (f)  The foregoing indemnification provisions shall be
the exclusive remedy for any breach of the representations, warranties,
covenants or obligations set forth in this Agreement; provided, however, that
the provision of this Section 9.1 shall not prevent Seller, on the one hand, or
Buyer, on the other hand, from seeking the remedies of specific performance or
injunctive relief in connection with a breach of a covenant of the other party
contained herein.

shall have been (i) delivered to the addressee by the return receipt (if
transmitted by mail or commercial delivery service), or the affidavit of the
messenger (if transmitted by personal delivery) or (ii) presented for delivery
to the addressee as so indicated during normal business hours, if such delivery
shall have been refused for any reason.

            9.3 INTERPRETATION. The words "INCLUDE," "INCLUDES" and "INCLUDING"
when used herein shall be deemed in each case to be followed by the words
"without limitation." The table of contents and headings contained in this
Agreement are for reference purposes only and shall not affect in any way the
interpretation of this Agreement.

            9.4 KNOWLEDGE DEFINED. The term "Knowledge" of Seller or
Buyer as used in this Agreement, with respect to any fact or circumstance,
shall mean any fact or circumstance which is actually known to any Principal
Stockholder of Seller or executive officer of Buyer or of which any Principal
Stockholder or executive office should have known in the performance of his
duties in a manner typical of executives of a business similar to the Cronus
Business or Buyer's business.

            9.5 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each
of the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart. Signature pages received by

            9.6 ENTIRE AGREEMENT; ASSIGNMENT.  This Agreement, the schedules
and Exhibits hereto, and the documents and instruments and other agreements

prior written consent of each party shall not be assigned by operation of law
or otherwise, except that Buyer may assign its rights and obligations hereunder

or delegation of duties under this Agreement by a party without the prior
written consent of the other parties, if such consent is required hereby, shall
be void.

            9.7 SEVERABILITY. If any provision of this Agreement shall
hereafter be held to be invalid, unenforceable or illegal, in whole or in part,
in any jurisdiction under any circumstances for any reason, (i) such provision
shall be reformed to the minimum extent necessary to cause such provision to be
valid, enforceable and legal while preserving the intent of the parties as
expressed in, and the benefits to the parties provided by, this Agreement or
(ii) if such provision cannot be so reformed, such provision shall be severed
from this Agreement and an equitable adjustment shall be made to this Agreement
(including, without limitation, addition of necessary further provisions to
this Agreement) so as to give effect to the intent as so expressed and the
benefits so provided. Such holding shall not affect or impair the validity,
enforceability or legality of such provision in any other jurisdiction or under
any other circumstances. Neither such holding nor such reformation or severance
shall affect or impair the legality, validity or enforceability of any other
provision of this Agreement.

            9.8 OTHER REMEDIES.  Except as otherwise provided herein, any and
all remedies herein expressly conferred upon a party will be deemed cumulative
with and not exclusive of any other remedy conferred hereby, or by law or equity
upon such party, and the exercise by a party of any one remedy will not preclude
the exercise of any other remedy. The Buyer is intended to be a third-party
beneficiary of the representations and warranties of the Principal Stockholders
contained herein and it is expressly acknowledged that no provision of this
Agreement (other than Article V) in any way limits or results in a waiver of any
right of Buyer to bring an action against the Principal Stockholders for damages
incurred by Buyer arising from or relating to any such breach.

reason, such registration statement is not filed with the Commission on or
before September 30, 2000, the Holder shall have the right to demand
registration of his Registrable Securities.  Upon receipt of such demand, the
Company shall, as promptly as practicable prepare and file with the Commission
a registration statement sufficient to permit the public offering of the
Registrable Securities and will use best efforts through it's officers,
directors, auditors, and counsel, in all matters necessary or advisable, to
cause such registration statement to become effective as promptly as
practicable; provided, however, the Company shall only be obligated to file one
such registration for the Registrable Securities;

                          (b)     prepare and file with the Commission such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to keep such registration
statement effective and to comply with the provisions of the Securities Act
with respect to the disposition of all Registrable Securities and other
securities covered by such registration statement until the earlier of such
time as all of such Registrable Securities and securities have been disposed of
in accordance with the intended methods of disposition by the Holder thereof
set forth in such registration statement or the expiration of one hundred and
eighty (180) days after such registration statement becomes effective; and will
furnish, within a reasonable time prior to filing, to the Holder's
Representative prior to the filing thereof a copy of any amendment or
supplement to such registration statement or prospectus and shall not file any
such amendment or supplement to which the Holder's Representative shall have
reasonably objected on the

<PAGE>   2

grounds that such amendment or supplement does not comply in all material
respects with the requirements of the Securities Act or of the rules or
regulations thereunder;

                          (c)     furnish to the Holder's Representative of
such Registrable Securities a copy of each such amendment and supplement
thereto (in each case including all exhibits), and such documents, if any,
incorporated by reference in such registration statement or prospectus, and
such other documents, as the Holder's Representatives may reasonably request;

                          (d)     use best efforts to register or qualify all
Registrable Securities and other securities covered by such registration
statement under such other securities or blue sky laws of the States of the
United States as the Holder shall reasonably request, to keep such registration
or qualification in effect for so long as such registration statement remains
in effect, and do any and all other acts and things which may be necessary or
advisable to enable the Holder to consummate the disposition in such
jurisdictions of his Registrable Securities offered by such registration
statement, except that the Company shall not for any such purpose be required
to qualify generally to do business as a foreign corporation in any
jurisdiction wherein it would not but for the requirements of this subsection
(d) be obligated to be so qualified, or to subject itself to taxation in any
such jurisdiction, or to consent general service of process in any such
jurisdiction;

                          In addition, the Company shall not be required to
qualify the Registrable Shares or any portion thereof in any jurisdiction where
the Registrable Shares do not meet the requirements of such jurisdiction.

                          (e)     upon request, furnish to the Holder of
Registrable Securities a signed counterpart, addressed to the Holder, an
opinion of counsel for the Company, dated the effective date of such
registration statement covering such items that are customarily covered in the
opinion of issuer's counsel delivered to underwriters in underwritten public
offerings of securities;

                          (f)     provide and cause to be maintained a transfer
agent and registrar for all Registrable Securities covered by such registration
statement from and after a date not later than the effective date of such
registration statement;

                          (g)     use best efforts to list all Registrable
Securities covered by such registration statement on each securities exchange
on which any of the Company's Common Stock is then listed or, if the Common
Stock is not then quoted on NASDAQ or listed on any national securities
exchange, use its best efforts to have such Company's Common Stock covered by
such registration statement quoted by NASDAQ or, at the option of the Company,
listed on a national securities exchange; and

                          (h)     Expenses.  Except as otherwise required by
applicable law, the Company shall pay all Registration Expenses in connection
with the registration of the Registrable Securities pursuant to Section 2.1.

                          (i)     Penalty.  If the Company has not filed the
Registration Statement referenced in this Section 2.1 within the time period
specified above and such non-filing was not caused by force majeure, then the
Company will pay to the Holder's Representative a penalty of $100,000.

                 2.2 Piggy-Back Registration.

                          (a)     Right to Include Registrable Shares.  If the
Company at any time proposes to register any of its securities under the
Securities Act (other than a registration on Form S-4, S-8, or any successor or
similar forms and other than pursuant to Section 2.1), for sale to the public
whether on its own account or on account of the other holders or both, it will
each such time give prompt written notice to the Holder's Representative of its
intention to do so and of the Holder's rights under this Section 2.2.  Upon the
written request of the Holder made within thirty (30) days after the receipt of
the notice (which request shall specify the Registrable Shares intended to be
disposed of by the Holder and the intended method of disposition thereof), the
Company will use its best efforts to effect the registration under the
Securities Act of all Registrable Shares which the Company has been so
requested to register by the Holder, to the extent requisite to permit the
disposition (in accordance with the intended methods thereof as aforesaid) of
the Registrable Shares so to be registered, by inclusion of such Registrable
Shares in the registration statement and, in the case of an underwritten
offering, the underwriting which covers the securities which the Company
proposes to register; provided, however, that if, at any time after giving
written notice or its intention to register any securities and prior to the
effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason either not to register
or to delay registration of such securities, the Company may, at its election,
give written notice of such determination to the Holder's Representative and,
upon the giving of such notice, (i) in the case of a determination not to
register, shall be relieved of its obligation to register any Registrable
Shares in connection with such registration (but shall pay all Registration
Expenses in connection therewith), and (ii) in the case of a determination to
delay registering, shall be permitted to delay registering such other
securities.  No registration effected under this Section 2.2 shall relieve the
Company of its obligation to effect the Primary Registration under Section 2.1.
The Holder's participation in any such piggyback registration shall not require
that he or she pay any portion of the Registration Expenses incurred by the
Company but such Holder shall pay the proportional amount of all underwriting
discounts and commissions applicable to Registrable Shares sold by it and fees
and disbursements of any legal counsel or accountants retained by such Holder.

                          (b)     Priority in Piggy-Back Registrations.  If (i)
a registration pursuant to this Section 2.2 involves an underwritten offering
of the securities so being registered to be distributed (on a firm commitment
basis) by or through one or more underwriters of recognized standing under
underwriting terms appropriate for such a transaction, and (ii) the managing
underwriter of such underwritten offering shall inform the Company and the
Holder's Representative (if any Registrable Shares held by the Holder have been
requested to be included in such underwritten offering) by letter of its belief
that the distribution of all or a specified number of the Registrable Shares
requested to be included concurrently with the securities being distributed by
such underwriters would interfere with the successful marketing of the
securities being distributed by such underwriters (such writing to state the
basis of such belief and the approximate number of the Registrable Shares
requested to be included which may be distributed without such effect), then
the Company may, upon written notice to the Holder's Representative, reduce (if
and to the extent stated by such managing underwriter to be necessary to
eliminate such effect) the number of the Registrable Shares, if any, requested
to be included so that the resultant aggregate number of the Registrable Shares
requested to be included that will be included in such registration shall be
equal to the number of shares stated in such managing underwriter's letter;
provided, however, that the priority in such registration shall be subject to
the following restriction.  The parties who received Common Stock of the
Company are divided into two classes: (1) former creditors, and (ii) former
stockholders of the Seller.  See Attachment 1 hereto.  To the extent that there
is a limit on the number of shares that can be registered, such shares shall be
registered in





                                       3
<PAGE>   4
the following order of priority: (i) stockholder-creditors of the Seller, and
(ii) non-creditor, stockholder of the Seller.

                          (c)     Expiration of Piggy-Back Rights.  The Company
shall not be obligated to include Registrable Shares in any registration
statement pursuant to this Section 2.2 that will become effective during a
period when the Holder thereof is eligible to sell such Registrable Shares
pursuant to the Commission's Rule 144.

                          (d)     Lack of Information.  The Company shall not
be required to register or cause the registration of the Registrable Shares or
any portion thereof pursuant to this Section 2.2 hereof if the Holder shall not
promptly supply the Company with any information about the Holder or his
Registrable Shares which the Company may reasonably and timely request in
written form in order to permit the preparation, filing and effectiveness of a
registration statement in accordance with the Securities Act and any rules and
regulations promulgated by the Commission thereunder.

                 2.3      Registration Procedures.  If and whenever the Company
is required to use best efforts to effect the registration of any Registrable
Shares under the Securities Act as provided in Sections 2.1 and 2.2 the Company
shall, as expeditiously as possible:

                          (i)     prepare and (within sixty (60) days after the
end of the period within which requests for registration may be given to the
Company or in any event as soon thereafter as possible) file with the
Commission the requisite registration statement to effect such registration and
thereafter use best efforts to cause such registration statement to become and
remain effective; provided, however, that the Company may discontinue any
registration of its securities which are not Registrable Shares (and, under the
circumstances specified in Section 2.2(a), its securities which are Registrable
Shares) at any time prior to the effective date of the registration statement
relating thereto;

                          (ii)    prepare and file with the Commission such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to keep such registration
statement effective and to comply with the provisions of the Securities Act
with respect to the disposition of all Registrable Shares covered by such
registration statement until the earlier of such time as all of such securities
have been disposed of in accordance with the intended methods of disposition by
the Holder thereof set forth in such registration statement or (a) in the case
of a registration pursuant to Section 2.1, the period of time specified in
Section 2.1, or (b) in the case of a registration pursuant to Section 2.2, the
expiration of one hundred eighty (180) days after such registration statement
becomes effective;

                          (iii)            furnish to the Holder's
Representative of the Registrable Shares covered by such registration statement
and each underwriter, if any, of the securities being sold by such seller such
number of conformed copies of such registration statement and of each such
amendment and supplement thereto (in each case including all exhibits), such
number of copies of the prospectus contained in such registration statement
(including each preliminary prospectus and any summary prospectus) and any
other prospectus filed under Rule 424 under the Securities Act, in conformity
with the requirements of the Securities Act, and such other documents, as the
Holder and underwriter, if any, may reasonably request in order to facilitate
the public sale or other disposition of the Registrable Shares owned by such
seller;





                                       4
<PAGE>   5
                          (iv)    use best efforts to register or qualify all
Registrable Shares and other securities covered by such registration statement
under such other securities laws or blue sky laws of such jurisdiction the
Holder and any underwriter of the securities being sold by such underwriter and
the Holder shall reasonably request, to keep such registration statement in
effect, and take any other action which may be reasonably necessary or
advisable to enable the Holder and underwriter to consummate the disposition in
such jurisdictions of the securities owned by such seller, except that the
Company shall not for any such purpose be required to qualify generally to do
business as a foreign corporation in any jurisdiction wherein it would not but
for the requirements of this subdivision (iv) be obligated to be so qualified,
to subject itself to taxation in any such jurisdiction or to consent to general
service of process in any such jurisdiction;

                          (v)     notify each seller of Registrable Shares
covered by such registration statement and the Holder, at any time when a
prospectus relating thereto is required to be delivered under the Securities
Act, upon the Company's discovery that, or upon the happening of any event as a
result of which, the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances under which
they were made, and at the request of any such seller or the Holder promptly
prepare and furnish to such seller or the Holder and each underwriter, if any,
a reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such securities, such prospectus shall not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
the light of the circumstances under which they were made; and

                 The Holder  agrees that, upon receipt of any notice from the
Company of the occurrence of any event of the kind described in subdivision (v)
of this Section 2.3, the Holder  will forthwith discontinue his disposition of
Registrable Shares until the Holder's receipt of the copies of the supplemented
or amended prospectus contemplated by subdivision (v) of this Section 2.3 and,
if so directed by the Company (at the Company's expense) all copies, other than
permanent file copies, then in the Holder's possession of the prospectus
relating to such Registrable Shares current at the time of receipt of such
notice.  In the event the Company shall give any such notice, the period
mentioned in paragraph (ii) of this Section 2.3 shall be extended by the length
of the period from and including the date when each seller of any Registrable
Shares covered by such registration statement shall have received such notice
to the date on which each such seller has received the copies of the
supplemented or amended prospectus contemplated by paragraph (v) of this
Section 2.3.

                 2.4      Underwritten Offerings.

                          (a)     Underwritten Piggy-Back Offerings.  The
Holder of Registrable Shares to be distributed by underwriters in a
registration pursuant to Section 2.2 shall be parties to the underwriting
agreement between the Company and such underwriters and may require that any or
all of the conditions precedent to the obligations of such underwriters under
such underwriting agreement also be conditions precedent to the obligations of
the Holder of Registrable Shares.  The Holder agrees to make such
representations or warranties to or agreements with the Company or the
underwriters as are customarily given to the underwriters and any other
representation required by law.





                                       5
<PAGE>   6
                          (b)     Holdback Agreements.  Holder agrees, if so
required by the managing underwriter, not to effect any public sale or
distribution of any securities of the Company during the seven days prior to
and the one hundred eighty (180) days (or such longer period as the managing
underwriter may reasonably require for all holdback agreements entered into
with holders of Common Stock) after any underwritten registration pursuant to
Section 2.2 has become effective (the "Holdback"), except as part of such
underwritten registration, whether or not such Holder participates in such
registration; provided however, that if a Holder does not participate in a
registration, such Holder shall not be subject to the Holdback beyond the
expiration of this Agreement, unless agreed to in writing.

                 2.5      Preparation; Reasonable Investigation.
Notwithstanding Section 2.1 hereof and despite a Request, the Company shall not
be required to file any registration statement, or if filed cause any
registration statement to become effective, if at the time the Holder makes a
Request, or during the period after filing but before effectiveness, the
Company is engaged in negotiations to acquire the stock or assets of any
business entity which would be required to make any public announcement
thereof; provided, however, no such delay occasioned under this Section shall
exceed ninety (90) days.  If, however, the Company shall take any action with
respect to the acquisition of the stock or assets of any business entity which
would require the Company to amend any prospectus included in a registration
statement which became effective under the provisions of Section 2.1 hereof by
including therein financial statements which conform to the requirements of
Regulation S-X promulgated by the Commission, the Holder agrees to suspend the
offering or sale of the Registrable Shares or any portion thereof for a period
not to exceed 90 days so that the Company may prepare such financial
statements, provided that the Company uses best efforts to prepare such
financial statements as promptly as possible and provided further that the
ninety (90) day period referred to in the first sentence of this Section shall
be extended for a period equivalent to the delay.

         The Company shall furnish the Holder's Representative with a printer's
proof of Part I of any registration statement sufficiently in advance of its
filing with the Commission to provide the Holder and it's counsel with a
reasonable opportunity for review and comment, which proof shall not be
materially different in content from Part I of the registration statement as
filed.  In addition, the Company shall furnish to the Holder's Representative,
within reasonable time prior to the filing thereof, a copy of any registration
statement as filed with the Commission and any amendments thereto, including if
requested, copies of any exhibits and consents filed therewith and of any
exhibits incorporated therein by reference, and shall not circulate any
preliminary prospectus until five (5) days after a copy of the same has been
furnished to the Holder's Representative.  In addition, the Company shall
furnish the Holder's Representative as many copies of any prospectuses (and of
any preliminary, amended or supplemented prospectuses) in connection with such
registration as the Holder's Representative may reasonably request.

         3.      Definitions.  As used herein, unless the context otherwise

not, without the prior written consent of the holders of at least a majority of
the outstanding Registrable Securities held by the Holders, enter into any
agreement with any holder or prospective holder of any securities of the

provided however, that the foregoing covenant shall be null and void upon the
earlier of (i) the Registration of the Registrable Shares pursuant to Section
2.1; (ii) the Registration of the Registrable Shares pursuant to Section 2.2;

                 (b)      The Company hereby represents and warrants that there
are no other registration rights which it has previously granted which are
superior to those stated herein, except as set forth in Attachment 2 hereof.

         5.      Rule 144.  The Company shall timely request and/or file the
reports required to be filed by it under the Securities Exchange Act of 1934
(including but not limited to the reports under Sections 13 and 15(d) of the
Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the
Commission under the Securities Act) and the rules and regulations adopted by
the Commission thereunder and will take such further action as any Holder of
Registrable Shares may reasonably request, all to the extent required from time

under the Securities Act within the limitation of the exemptions provided by
(a) Rule 144 under the Securities Act, as such Rule may be amended from time to

    (which shall not constitute notice to Holder or Holder's Representative)

or at such address as the party addressed may from time to time designate in
writing to the other parties in like manner.  Any communication dispatched by
telecopy shall be confirmed by letter.

         9.      Indemnification.  The Company and the Holder agree to
indemnify each other on the terms and conditions set forth below:

                 (a)      Indemnification by the Company.  The Company will
indemnify and hold harmless the Holder and each underwriter (as defined in the
Securities Act) employed by the Holder (including any broker or dealer through
whom the shares may be sold) and each person, if any, who controls the Holder
or any such underwriter within the meaning of the Securities Act from and
against any and all losses, claims, damages, expenses or liabilities, joint or
several, to which they or any of them may become subject under the Securities
Act or under any other statute or at common law or otherwise, including the
Blue Sky laws of the various jurisdictions, and, except as hereinafter
provided, will reimburse the Holder and each of the underwriters and each such
controlling person, if any, for any legal or other expenses reasonably incurred
by them or any of them in connection with investigating or defending any
actions whether or not resulting in any liability, insofar as such losses,
claims, damages, expenses, liabilities or actions arise out of or are based
upon any untrue statement of a material fact, or omission to state a material
fact required to be stated therein or necessary in order to make the statements
therein not misleading, contained in any registration statement, preliminary or
amended prospectus or any prospectus (or any registration statement or
prospectus as from time to time amended or supplemented by the Company) which
the Company  shall file pursuant to either Sections 2.1 or 2.2 hereof, unless
such untrue statement or omission was made in such registration statement,
preliminary or amended preliminary prospectus or prospectus (or any
registration statement or prospectus as from time to time amended or
supplemented by the Company) in reliance upon and in conformity with
information furnished in writing to the Company by the Holder or any
underwriter employed by the Holder and arising out of any violations by the
Company of any rule or regulation promulgated under the Securities Act
applicable to the Company in connection with such registration.  Promptly after
receipt by the Holder or any underwriter or any person controlling the Holder
or such underwriter of notice of the commencement of any action (but in no
event later than ten (10) days prior to the time any notice of appearance or
any response thereto is required) in respect of which indemnity may be sought
against the Company, the Holder or such underwriter, as the case may be, shall
notify the Company in writing of the commencement thereof, and, subject to the
provisions hereinafter stated, the Company shall assume the defense of such
action (including the employment of counsel) insofar as such action shall
relate to any alleged liability in respect of which indemnity may be sought
against the Company.  The Holder or any underwriter or any such controlling





                                       9
<PAGE>   10

person shall have the right to employ separate counsel in any such action and
to participate in the defense thereof, but the fees and expenses of such
counsel shall not be at the expense of the Company unless the employment of
such counsel has been specifically authorized by it.  The Company shall not be
liable to indemnify any person, as required by this Section, for any settlement
of any such action effected without its consent, nor shall it be liable to
indemnify any person unless it shall be notified of the commencement of any
action within the time limits and as set forth above.

                 (b)      Indemnification by the Holder.  The Holder will
indemnify and hold harmless the Company, each of its directors and officers who
have signed the registration statement and each person, if any, who controls
the Company with the meaning of Section 15 of the Securities Act from and
against any and all losses, claims, damages, expenses or liabilities, joint or
several, to which they or any of them may become subject under the Securities
Act or under any other statute or at common law or otherwise, including the
Blue Sky laws of the various jurisdictions, and except as hereinafter provided,
will reimburse the Company and each such director, officer or controlling
person for any legal or other expenses reasonably incurred by them or any of
them in connection with investigating or defending any actions whether or not
resulting in any liability, insofar as such losses, claims, damages, expenses,
liabilities or actions arise out of or are based upon any untrue statement of
material fact, or an omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein not
misleading, contained in any registration statement, any preliminary or amended
preliminary prospectus or in any prospectus (or the registration statement or
prospectus as from time to time amended or supplemented) which the Company
shall file pursuant to Sections 2.1 or 2.2 hereof, but only insofar as any such
statement or omission was made in reliance upon and in conformity with
information furnished in writing to the Company by the Holder or any
underwriter employed by the Holder.  Promptly after receipt of notice of the
commencement of any action in respect of which indemnity may be sought against
the Holder (but in no event later than ten (10) days prior to the time any
notice of appearance or any response thereto is required) the Company shall
notify the Holder in writing of the commencement thereof, and the Holder shall,
subject to the provisions hereinafter stated, assume the defense of such action
(including the employment of counsel) insofar as such action shall relate to
any alleged liability in respect of which indemnity may be sought against the
Holder.  The Company and each director, officer or controlling person shall
have the right to employ separate counsel in any such action and to participate
in the defense thereof, but the fees and expenses of such counsel shall not be
at the expense of the Holder unless the employment of such counsel has been
specifically authorized by him.  The Holder shall not be liable to indemnify
any person, as required by this Section, for any settlement of any such action
effected without the Holder's consent, nor shall he be liable to indemnify any
person unless he shall be notified of the commencement of any action within the
time limits and as set forth above.

         10.     Miscellaneous.

                 (a)      Assignment.  This Agreement and the rights, interests
and obligations hereunder shall be binding upon and inure to the benefit of and
be enforceable by the parties hereto and their respective successors and
assigns.  In addition, and whether or not any express assignment shall have
been made, the provisions of this Agreement which are for the benefit of the
parties hereto other than the Company shall also be for the benefit of and
enforceable by any subsequent Holder of any Registrable Shares.  Any assignment
pursuant hereto by either party shall be consented in writing, and any such
written consent shall not be unreasonably withheld by either party.





                                       10
<PAGE>   11
                 (b)      No Third-Party Beneficiaries.  Except for the
provisions of Section 9(a) and (b) this Agreement is for the sole benefit of
the parties hereto and their respective successors and permitted assigns and
nothing herein expressed or implied shall give or be construed to give to any
Person, other than the parties hereto and such successors and assigns, any
legal or equitable rights hereunder, except to the extent otherwise provided in
this Agreement.

                 (c)      Descriptive Headings.  The descriptive headings of
the several sections and paragraphs of this Agreement are inserted for
reference only and shall not limit or otherwise affect the meaning hereof.

                 (d)      Waivers.  No failure or delay of any party in
exercising any power or right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power.  The rights and remedies of the parties hereunder are
cumulative and are not exclusive of any rights or remedies which the parties
would otherwise have.  No waiver of any provision of this Agreement or consent
to any departure by the Company therefrom shall in any event be effective
unless the same shall be effected in accordance with this Section 10(d), and
then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given.  No notice or demand on the Company in any
case shall entitle the Company to any other or further notice or demand in
similar or other circumstances.  Neither this Agreement nor any provision
hereof may be waived, amended or modified except pursuant to prior written
consent of the Holders.

                 (e)      Governing Law.  This Agreement shall be construed and
enforced in accordance with, and the rights of the parties shall be governed
by, the laws of the Commonwealth of Virginia without reference to the
principles of conflicts of laws.

                 (f)      Counterparts.  This Agreement may be executed
simultaneously in any number of counterparts, and may be executed in any number
of counterparts, each of which shall be deemed an original, but all such
counterparts shall together constitute one and the same instrument.

                 (g)      Entire Agreement.  This Agreement embodies the entire
agreement and understanding between the Company and each other party hereto and
supersedes all prior agreements and understandings related to the subject
matter hereof.

                 (h)      Severability.  In the event that any one or more of
the provisions contained herein, or the application thereof in any
circumstance, is held invalid, illegal or unenforceable in any respect for any
reason, the validity, legality and enforceability of any such provision in
every other respect and of the remaining provisions held invalid, illegal or
unenforceable shall substantially impair the benefits of the remaining
provisions hereof.



         IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed and delivered as of the date first above written.

                     FORM OF REGISTRATION RIGHTS AGREEMENT


                 REGISTRATION RIGHTS AGREEMENT, dated as of March 31, 2000
between FastComm Communications Corporation, a Virginia corporation (the
"Company"), and _________________________ (the "Holder").

                 1.       Introduction.  Pursuant to an Agreement and Plan of
Reorganization dated as of March 27, 2000 among the Company, Cronus Technology,
Inc., Cronus Communications Inc, and certain Principal Stockholders of Cronus
Technology, Inc. (the "Seller") (the "Agreement"), the Board of Directors of
the Company has authorized the grant of certain registration rights to the
Holder on the terms and conditions set forth herein.

                 2.       Registration under the Securities Act.  The Holder
shall have the registration rights specified below:

                          2.1     Primary Registration.  The Company will use
best efforts to affect the registration under the Securities Act of the
Registrable Shares within 45 days after the Company has filed its Annual Report
on form 10-K for the Company's year 2000 fiscal year.  In that regard, the
Company will:

                                  (a)      prepare and file with the Commission
a registration statement on any form that the Company is eligible to use, such
form to be selected by the Company after consultation with counsel, with
respect to such Registrable Securities and use best efforts to cause such
registration statement to become effective as soon as practicable.  If, for any
reason, such registration statement is not filed with the Commission on or
before September 30, 2000, the Holder shall have the right to demand
registration of his Registrable Securities. Upon receipt of such demand, the
Company shall, as promptly as practicable prepare and file with the Commission
a registration statement sufficient to permit the public offering of the
Registrable Securities and will use best efforts through it's officers,
directors, auditors, and counsel, in all matters necessary or advisable, to
cause such registration statement to become effective as promptly as
practicable; provided, however, the Company shall only be obligated to file one
such registration for the Registrable Securities;

                                  (b)      prepare and file with the Commission
such amendments and supplements to such registration statement and the
prospectus used in connection therewith as may be necessary to keep such
registration statement effective and to comply with the provisions of the
Securities Act with respect to the disposition of all Registrable Securities
and other securities covered by such registration statement until the earlier
of such time as all of such Registrable Securities and securities have been
disposed of in accordance with the intended methods of disposition by the
Holder thereof set forth in such registration statement or the expiration of
one

<PAGE>   2

hundred and eighty (180) days after such registration statement becomes
effective; and will furnish, within a reasonable time prior to filing, to the
Holder's Representative prior to the filing thereof a copy of any amendment or
supplement to such registration statement or prospectus and shall not file any
such amendment or supplement to which the Holder's Representative shall have
reasonably objected on the grounds that such amendment or supplement does not
comply in all material respects with the requirements of the Securities Act or
of the rules or regulations thereunder;

                                  (c)      furnish to the Holder's
Representative of such Registrable Securities a copy of each such amendment and
supplement thereto (in each case including all exhibits), and such documents,
if any, incorporated by reference in such registration statement or prospectus,
and such other documents, as the Holder's Representatives may reasonably
request;

                                  (d)      use best efforts to register or
qualify all Registrable Securities and other securities covered by such
registration statement under such other securities or blue sky laws of the
States of the United States as the Holder shall reasonably request, to keep
such registration or qualification in effect for so long as such registration
statement remains in effect, and do any and all other acts and things which may
be necessary or advisable to enable the Holder to consummate the disposition in
such jurisdictions of his Registrable Securities offered by such registration
statement, except that the Company shall not for any such purpose be required
to qualify generally to do business as a foreign corporation in any
jurisdiction wherein it would not but for the requirements of this subsection
(d) be obligated to be so qualified, or to subject itself to taxation in any
such jurisdiction, or to consent general service of process in any such
jurisdiction;

                                  In addition, the Company shall not be
required to qualify the Registrable Shares or any portion thereof in any
jurisdiction where the Registrable Shares do not meet the requirements of such
jurisdiction.

                                  (e)      upon request, furnish to the Holder
of Registrable Securities a signed counterpart, addressed to the Holder, an
opinion of counsel for the Company, dated the effective date of such
registration statement covering such items that are customarily covered in the
opinion of issuer's counsel delivered to underwriters in underwritten public
offerings of securities;

                                  (f)      provide and cause to be maintained a
transfer agent and registrar for all Registrable Securities covered by such
registration statement from and after a date not later than the effective date
of such registration statement;

                                  (g)      use best efforts to list all
Registrable Securities covered by such registration statement on each
securities exchange on which any of the Company's Common Stock is then listed
or, if the Common Stock is not then quoted on NASDAQ or listed on any national
securities exchange, use its best efforts to have such Company's Common Stock
covered by such registration statement quoted by NASDAQ or, at the option of
the Company, listed on a national securities exchange; and

                                  (h)      Expenses.  Except as otherwise
required by applicable law, the Company shall pay all Registration Expenses in
connection with the registration of the Registrable Securities pursuant to
Section 2.1.



                                       2
<PAGE>   3
                                  (i)      Penalty.  If the Company has not
filed the Registration Statement referenced in this Section 2.1 within the time
period specified above and such non-filing was not caused by force majeure,
then the Company will pay to the Holder's Representative a penalty of $100,000.

                          2.2 Piggy-Back Registration.

                                  (a)      Right to Include Registrable Shares.
If the Company at any time proposes to register any of its securities under the
Securities Act (other than a registration on Form S-4, S-8, or any successor or
similar forms and other than pursuant to Section 2.1), for sale to the public
whether on its own account or on account of the other holders or both, it will
each such time give prompt written notice to the Holder's Representative of its
intention to do so and of the Holder's rights under this Section 2.2.  Upon the
written request of the Holder made within thirty (30) days after the receipt of
the notice (which request shall specify the Registrable Shares intended to be
disposed of by the Holder and the intended method of disposition thereof), the
Company will use its best efforts to effect the registration under the
Securities Act of all Registrable Shares which the Company has been so
requested to register by the Holder, to the extent requisite to permit the
disposition (in accordance with the intended methods thereof as aforesaid) of
the Registrable Shares so to be registered, by inclusion of such Registrable
Shares in the registration statement and, in the case of an underwritten
offering, the underwriting which covers the securities which the Company
proposes to register; provided, however, that if, at any time after giving
written notice or its intention to register any securities and prior to the
effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason either not to register
or to delay registration of such securities, the Company may, at its election,
give written notice of such determination to the Holder's Representative and,
upon the giving of such notice, (i) in the case of a determination not to
register, shall be relieved of its obligation to register any Registrable
Shares in connection with such registration (but shall pay all Registration
Expenses in connection therewith), and (ii) in the case of a determination to
delay registering, shall be permitted to delay registering such other
securities.  No registration effected under this Section 2.2 shall relieve the
Company of its obligation to effect the Primary Registration under Section 2.1.
The Holder's participation in any such piggyback registration shall not require
that he or she pay any portion of the Registration Expenses incurred by the
Company but such Holder shall pay the proportional amount of all underwriting
discounts and commissions applicable to Registrable Shares sold by it and fees
and disbursements of any legal counsel or accountants retained by such Holder.

                                  (b)      Priority in Piggy-Back
Registrations.  If (i) a registration pursuant to this Section 2.2 involves an
underwritten offering of the securities so being registered to be distributed
(on a firm commitment basis) by or through one or more underwriters of
recognized standing under underwriting terms appropriate for such a
transaction, and (ii) the managing underwriter of such underwritten offering
shall inform the Company and the Holder's Representative (if any Registrable
Shares held by the Holder have been requested to be included in such
underwritten offering) by letter of its belief that the distribution of all or
a specified number of the Registrable Shares requested to be included
concurrently with the securities being distributed by such underwriters would
interfere with the successful marketing of the securities being distributed by
such underwriters (such writing to state the basis of such belief and the
approximate number of





                                       3
<PAGE>   4
the Registrable Shares requested to be included which may be distributed
without such effect), then the Company may, upon written notice to the Holder's
Representative, reduce (if and to the extent stated by such managing
underwriter to be necessary to eliminate such effect) the number of the
Registrable Shares, if any, requested to be included so that the resultant
aggregate number of the Registrable Shares requested to be included that will
be included in such registration shall be equal to the number of shares stated
in such managing underwriter's letter; provided, however, that the priority in
such registration shall be subject to the following restriction.  The parties
who received Common Stock of the Company are divided into two classes: (1)
former creditors, and (ii) former stockholders of the Seller.  See Attachment 1
hereto.  To the extent that there is a limit on the number of shares that can
be registered, such shares shall be registered in the following order of
priority: (i) stockholder-creditors of the Seller, and (ii) non-creditor,
stockholder of the Seller.

                                  (c)      Expiration of Piggy-Back Rights.
The Company shall not be obligated to include Registrable Shares in any
registration statement pursuant to this Section 2.2 that will become effective
during a period when the Holder thereof is eligible to sell such Registrable
Shares pursuant to the Commission's Rule 144.

                                  (d)      Lack of Information.  The Company
shall not be required to register or cause the registration of the Registrable
Shares or any portion thereof pursuant to this Section 2.2 hereof if the Holder
shall not promptly supply the Company with any information about the Holder or
his Registrable Shares which the Company may reasonably and timely request in
written form in order to permit the preparation, filing and effectiveness of a
registration statement in accordance with the Securities Act and any rules and
regulations promulgated by the Commission thereunder.

                          2.3     Registration Procedures.  If and whenever the
Company is required to use best efforts to effect the registration of any
Registrable Shares under the Securities Act as provided in Sections 2.1 and 2.2
the Company shall, as expeditiously as possible:

                                  (i)      prepare and (within sixty (60) days
after the end of the period within which requests for registration may be given
to the Company or in any event as soon thereafter as possible) file with the
Commission the requisite registration statement to effect such registration and
thereafter use best efforts to cause such registration statement to become and
remain effective; provided, however, that the Company may discontinue any
registration of its securities which are not Registrable Shares (and, under the
circumstances specified in Section 2.2(a), its securities which are Registrable
Shares) at any time prior to the effective date of the registration statement
relating thereto;

                                  (ii)     prepare and file with the Commission
such amendments and supplements to such registration statement and the
prospectus used in connection therewith as may be necessary to keep such
registration statement effective and to comply with the provisions of the
Securities Act with respect to the disposition of all Registrable Shares
covered by such registration statement until the earlier of such time as all of
such securities have been disposed of in accordance with the intended methods
of disposition by the Holder thereof set forth in such registration statement
or (a) in the case of a registration pursuant to Section 2.1, the period of
time specified in Section 2.1, or (b) in the case of a registration pursuant to
Section 2.2, the expiration of one hundred eighty (180) days after such
registration statement becomes effective;





                                       4
<PAGE>   5
                                  (iii)            furnish to the Holder's
Representative of the Registrable Shares covered by such registration statement
and each underwriter, if any, of the securities being sold by such seller such
number of conformed copies of such registration statement and of each such
amendment and supplement thereto (in each case including all exhibits), such
number of copies of the prospectus contained in such registration statement
(including each preliminary prospectus and any summary prospectus) and any
other prospectus filed under Rule 424 under the Securities Act, in conformity
with the requirements of the Securities Act, and such other documents, as the
Holder and underwriter, if any, may reasonably request in order to facilitate
the public sale or other disposition of the Registrable Shares owned by such
seller;

                                  (iv)     use best efforts to register or
qualify all Registrable Shares and other securities covered by such
registration statement under such other securities laws or blue sky laws of
such jurisdiction the Holder and any underwriter of the securities being sold
by such underwriter and the Holder shall reasonably request, to keep such
registration statement in effect, and take any other action which may be
reasonably necessary or advisable to enable the Holder and underwriter to
consummate the disposition in such jurisdictions of the securities owned by
such seller, except that the Company shall not for any such purpose be required
to qualify generally to do business as a foreign corporation in any
jurisdiction wherein it would not but for the requirements of this subdivision
(iv) be obligated to be so qualified, to subject itself to taxation in any such
jurisdiction or to consent to general service of process in any such
jurisdiction;

                                  (v)      notify each seller of Registrable
Shares covered by such registration statement and the Holder, at any time when
a prospectus relating thereto is required to be delivered under the Securities
Act, upon the Company's discovery that, or upon the happening of any event as a
result of which, the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances under which
they were made, and at the request of any such seller or the Holder promptly
prepare and furnish to such seller or the Holder and each underwriter, if any,
a reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such securities, such prospectus shall not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
the light of the circumstances under which they were made; and

                          The Holder  agrees that, upon receipt of any notice
from the Company of the occurrence of any event of the kind described in
subdivision (v) of this Section 2.3, the Holder  will forthwith discontinue his
disposition of Registrable Shares until the Holder's receipt of the copies of
the supplemented or amended prospectus contemplated by subdivision (v) of this
Section 2.3 and, if so directed by the Company (at the Company's expense) all
copies, other than permanent file copies, then in the Holder's possession of
the prospectus relating to such Registrable Shares current at the time of
receipt of such notice.  In the event the Company shall give any such notice,
the period mentioned in paragraph (ii) of this Section 2.3 shall be extended by
the length of the period from and including the date when each seller of any
Registrable Shares covered by such registration statement shall have received
such notice to the date on which each such seller has received the





                                       5
<PAGE>   6
copies of the supplemented or amended prospectus contemplated by paragraph (v)
of this Section 2.3.

                          2.4     Underwritten Offerings.

                                  (a)      Underwritten Piggy-Back Offerings.
The Holder of Registrable Shares to be distributed by underwriters in a
registration pursuant to Section 2.2 shall be parties to the underwriting
agreement between the Company and such underwriters and may require that any or
all of the conditions precedent to the obligations of such underwriters under
such underwriting agreement also be conditions precedent to the obligations of
the Holder of Registrable Shares.  The Holder agrees to make such
representations or warranties to or agreements with the Company or the
underwriters as are customarily given to the underwriters and any other
representation required by law.

                                  (b)      Holdback Agreements.  Holder agrees,
if so required by the managing underwriter, not to effect any public sale or
distribution of any securities of the Company during the seven days prior to
and the one hundred eighty (180) days (or such longer period as the managing
underwriter may reasonably require for all holdback agreements entered into
with holders of Common Stock) after any underwritten registration pursuant to
Section 2.2 has become effective (the "Holdback"), except as part of such
underwritten registration, whether or not such Holder participates in such
registration; provided however, that if a Holder does not participate in a
registration, such Holder shall not be subject to the Holdback beyond the
expiration of this Agreement, unless agreed to in writing.

                          2.5     Preparation; Reasonable Investigation.
Notwithstanding Section 2.1 hereof and despite a Request, the Company shall not
be required to file any registration statement, or if filed cause any
registration statement to become effective, if at the time the Holder makes a
Request, or during the period after filing but before effectiveness, the
Company is engaged in negotiations to acquire the stock or assets of any
business entity which would be required to make any public announcement
thereof; provided, however, no such delay occasioned under this Section shall
exceed ninety (90) days.  If, however, the Company shall take any action with
respect to the acquisition of the stock or assets of any business entity which
would require the Company to amend any prospectus included in a registration
statement which became effective under the provisions of Section 2.1 hereof by
including therein financial statements which conform to the requirements of
Regulation S-X promulgated by the Commission, the Holder agrees to suspend the
offering or sale of the Registrable Shares or any portion thereof for a period
not to exceed 90 days so that the Company may prepare such financial
statements, provided that the Company uses best efforts to prepare such
financial statements as promptly as possible and provided further that the
ninety (90) day period referred to in the first sentence of this Section shall
be extended for a period equivalent to the delay.

                 The Company shall furnish the Holder's Representative with a
printer's proof of Part I of any registration statement sufficiently in advance
of its filing with the Commission to provide the Holder and it's counsel with a
reasonable opportunity for review and comment, which proof shall not be
materially different in content from Part I of the registration statement as
filed.  In addition, the Company shall furnish to the Holder's Representative,
within reasonable time prior to the filing





                                       6
<PAGE>   7
thereof, a copy of any registration statement as filed with the Commission and
any amendments thereto, including if requested, copies of any exhibits and
consents filed therewith and of any exhibits incorporated therein by reference,
and shall not circulate any preliminary prospectus until five (5) days after a
copy of the same has been furnished to the Holder's Representative.  In
addition, the Company shall furnish the Holder's Representative as many copies
of any prospectuses (and of any preliminary, amended or supplemented
prospectuses) in connection with such registration as the Holder's
Representative may reasonably request.

                 9.       Indemnification.  The Company and the Holder agree to
indemnify each other on the terms and conditions set forth below:

                          (a)     Indemnification by the Company.  The Company
will indemnify and hold harmless the Holder and each underwriter (as defined in
the Securities Act) employed by the Holder (including any broker or dealer
through whom the shares may be sold) and each person, if any, who controls the
Holder or any such underwriter within the meaning of the Securities Act from
and against any and all losses, claims, damages, expenses or liabilities, joint
or several, to which they or any of them may become subject under the
Securities Act or under any other statute or at common law or otherwise,
including the Blue Sky laws of the various jurisdictions, and, except as
hereinafter





                                       9
<PAGE>   10
provided, will reimburse the Holder and each of the underwriters and each such
controlling person, if any, for any legal or other expenses reasonably incurred
by them or any of them in connection with investigating or defending any
actions whether or not resulting in any liability, insofar as such losses,
claims, damages, expenses, liabilities or actions arise out of or are based
upon any untrue statement of a material fact, or omission to state a material
fact required to be stated therein or necessary in order to make the statements
therein not misleading, contained in any registration statement, preliminary or
amended prospectus or any prospectus (or any registration statement or
prospectus as from time to time amended or supplemented by the Company) which
the Company  shall file pursuant to either Sections 2.1 or 2.2 hereof, unless
such untrue statement or omission was made in such registration statement,
preliminary or amended preliminary prospectus or prospectus (or any
registration statement or prospectus as from time to time amended or
supplemented by the Company) in reliance upon and in conformity with
information furnished in writing to the Company by the Holder or any
underwriter employed by the Holder and arising out of any violations by the
Company of any rule or regulation promulgated under the Securities Act
applicable to the Company in connection with such registration.  Promptly after
receipt by the Holder or any underwriter or any person controlling the Holder
or such underwriter of notice of the commencement of any action (but in no
event later than ten (10) days prior to the time any notice of appearance or
any response thereto is required) in respect of which indemnity may be sought
against the Company, the Holder or such underwriter, as the case may be, shall
notify the Company in writing of the commencement thereof, and, subject to the
provisions hereinafter stated, the Company shall assume the defense of such
action (including the employment of counsel) insofar as such action shall
relate to any alleged liability in respect of which indemnity may be sought
against the Company.  The Holder or any underwriter or any such controlling
person shall have the right to employ separate counsel in any such action and
to participate in the defense thereof, but the fees and expenses of such
counsel shall not be at the expense of the Company unless the employment of
such counsel has been specifically authorized by it.  The Company shall not be
liable to indemnify any person, as required by this Section, for any settlement
of any such action effected without its consent, nor shall it be liable to
indemnify any person unless it shall be notified of the commencement of any
action within the time limits and as set forth above.


                          (b)     Indemnification by the Holder.  The Holder
will indemnify and hold harmless the Company, each of its directors and
officers who have signed the registration statement and each person, if any,
who controls the Company with the meaning of Section 15 of the Securities Act
from and against any and all losses, claims, damages, expenses or liabilities,
joint or several, to which they or any of them may become subject under the
Securities Act or under any other statute or at common law or otherwise,
including the Blue Sky laws of the various jurisdictions, and except as
hereinafter provided, will reimburse the Company and each such director,
officer or controlling person for any legal or other expenses reasonably
incurred by them or any of them in connection with investigating or defending
any actions whether or not resulting in any liability, insofar as such losses,
claims, damages, expenses, liabilities or actions arise out of or are based
upon any untrue statement of material fact, or an omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein not misleading, contained in any registration statement, any
preliminary or amended preliminary prospectus or in any prospectus (or the
registration statement or prospectus as from time to time amended or
supplemented) which the Company shall file pursuant to Sections 2.1 or 2.2
hereof, but only insofar as any such statement or





                                       10
<PAGE>   11
omission was made in reliance upon and in conformity with information furnished
in writing to the Company by the Holder or any underwriter employed by the
Holder.  Promptly after receipt of notice of the commencement of any action in
respect of which indemnity may be sought against the Holder (but in no event
later than ten (10) days prior to the time any notice of appearance or any
response thereto is required) the Company shall notify the Holder in writing of
the commencement thereof, and the Holder shall, subject to the provisions
hereinafter stated, assume the defense of such action (including the employment
of counsel) insofar as such action shall relate to any alleged liability in
respect of which indemnity may be sought against the Holder.  The Company and
each director, officer or controlling person shall have the right to employ
separate counsel in any such action and to participate in the defense thereof,
but the fees and expenses of such counsel shall not be at the expense of the
Holder unless the employment of such counsel has been specifically authorized
by him.  The Holder shall not be liable to indemnify any person, as required by
this Section, for any settlement of any such action effected without the
Holder's consent, nor shall he be liable to indemnify any person unless he
shall be notified of the commencement of any action within the time limits and
as set forth above.

                 10.      Miscellaneous.

                          (a)     Assignment.  This Agreement and the rights,
interests and obligations hereunder shall be binding upon and inure to the
benefit of and be enforceable by the parties hereto and their respective
successors and assigns.  In addition, and whether or not any express assignment
shall have been made, the provisions of this Agreement which are for the
benefit of the parties hereto other than the Company shall also be for the
benefit of and enforceable by any subsequent Holder of any Registrable Shares.
Any assignment pursuant hereto by either party shall be consented in writing,
and any such written consent shall not be unreasonably withheld by either
party.

                          (b)     No Third-Party Beneficiaries.  Except for the
provisions of Section 9(a) and (b) this Agreement is for the sole benefit of
the parties hereto and their respective successors and permitted assigns and
nothing herein expressed or implied shall give or be construed to give to any
Person, other than the parties hereto and such successors and assigns, any
legal or equitable rights hereunder, except to the extent otherwise provided in
this Agreement.

                          (c)     Descriptive Headings.  The descriptive
headings of the several sections and paragraphs of this Agreement are inserted
for reference only and shall not limit or otherwise affect the meaning hereof.

                          (d)     Waivers.  No failure or delay of any party in
exercising any power or right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power.  The rights and remedies of the parties hereunder are
cumulative and are not exclusive of any rights or remedies which the parties
would otherwise have.  No waiver of any provision of this Agreement or consent
to any departure by the Company therefrom shall in any event be effective
unless the same shall be effected in accordance with this Section 10(d), and
then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given.  No notice or demand on the





                                       11
<PAGE>   12
Company in any case shall entitle the Company to any other or further notice or
demand in similar or other circumstances.  Neither this Agreement nor any
provision hereof may be waived, amended or modified except pursuant to prior
written consent of the Holders.

                          (e)     Governing Law.  This Agreement shall be
construed and enforced in accordance with, and the rights of the parties shall
be governed by, the laws of the Commonwealth of Virginia without reference to
the principles of conflicts of laws.

                          (f)     Counterparts.  This Agreement may be executed
simultaneously in any number of counterparts, and may be executed in any number
of counterparts, each of which shall be deemed an original, but all such
counterparts shall together constitute one and the same instrument.

                          (g)     Entire Agreement.  This Agreement embodies
the entire agreement and understanding between the Company and each other party
hereto and supersedes all prior agreements and understandings related to the
subject matter hereof.

                          (h)     Severability.  In the event that any one or
more of the provisions contained herein, or the application thereof in any
circumstance, is held invalid, illegal or unenforceable in any respect for any
reason, the validity, legality and enforceability of any such provision in
every other respect and of the remaining provisions held invalid, illegal or
unenforceable shall substantially impair the benefits of the remaining
provisions hereof.

                 IN WITNESS WHEREOF, the parties have caused this Agreement to
be executed and delivered as of the date first above written.

<PAGE>   2


       MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES. Subject
       to the provisions hereof, this Warrant may be exercised by the Holder
       hereof, by the surrender of this Warrant, together with a completed
       exercise agreement in the form attached hereto (the "EXERCISE
       AGREEMENT"), to the Company during normal business hours on any business
       day at the Company's principal executive offices (or such other office or
       agency of the Company as it may designate by notice to the Holder
       hereof), and upon payment to the Company in cash, by certified or
       official bank check or by wire transfer for the account of the Company,
       of the Exercise Price for all of the Warrant Shares. The Warrant Shares
       so purchased shall be deemed to be issued to the Holder hereof, as the
       record owner of such shares, as of the close of business on the date on
       which this Warrant shall have been surrendered, the completed Exercise
       Agreement shall have been delivered, and payment shall have been made for
       such shares as set forth above. THE WARRANT SHARES SO PURCHASED WILL BE
       "RESTRICTED" AND UNREGISTERED SHARES. Certificates for the Warrant Shares
       so purchased, representing the aggregate number of shares specified in
       the Exercise Agreement, shall be delivered to the Holder hereof within a
       reasonable time, not exceeding twenty (20) business days, after this
       Warrant shall have been so exercised. The certificates so delivered shall
       be in such denominations as may be requested by the Holder hereof and
       shall be registered in the name of such Holder.

1.     PERIOD OF EXERCISE. This Warrant is exercisable at any time or from time
       to time on or after the date on which this Warrant is issued and before
       5:00 p.m. New York City time on the second (2nd) anniversary of the date
       of issuance (the "EXERCISE PERIOD").

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

(a)    SHARES TO BE FULLY PAID. All Warrant Shares will, upon issuance in
       accordance with the terms of this Warrant, be validly issued, fully paid,
       and non-assessable and free from all taxes, liens, claims and
       encumbrances.

(b)    RESERVATION OF SHARES. During the Exercise Period, the Company shall at
       all times have authorized, and reserved for the purpose of issuance upon
       exercise of this Warrant, a sufficient number of shares of Common Stock
       to provide for the exercise of this Warrant.

(c)    LISTING. The Company will secure the listing of the shares of Common
       Stock issuable upon exercise of this Warrant upon the automated quotation
       system, the OTC Bulletin Board or on any other system or exchange on
       which the Company shares may hereafter be listed or traded, upon which
       shares of Common Stock are currently listed and shall maintain, so long
       as any other shares of Common Stock shall be so listed, such listing of
       all shares of Common Stock issuable upon the exercise of this Warrant;
       and the Company shall so list on such automated quotation system and
       shall maintain such listing of, any other shares of capital stock of the
       Company issuable upon the exercise of this Warrant if and so long as any
       shares of the same class shall be listed on such automated quotation
       system.




                                       2
<PAGE>   3

(d)    CERTAIN ACTIONS PROHIBITED. The Company will not, by amendment of its
       charter or through any reorganization, transfer of assets, consolidation,
       merger, dissolution, issue or sale of securities, or any other voluntary
       action, avoid or seek to avoid the observance or performance of any of
       the terms to be observed or performed by it hereunder, but will at all
       times in good faith assist in the carrying out of all the provisions of
       this Warrant and in the taking of all such action as may reasonably be
       requested by the Holder of this Warrant in order to protect the exercise
       privilege of the Holder of this Warrant during the exercise period.
       Without limiting the generality of the foregoing, the Company (i) will
       not increase the par value of any shares of Common Stock receivable upon
       the exercise of this Warrant above the Exercise Price then in effect, and
       (ii) will take all such actions as may be necessary or appropriate in
       order that the Company may validly and legally issue fully paid and
       non-assessable shares of Common Stock upon the exercise of this Warrant.

(e)    SUCCESSORS AND ASSIGNS. This Warrant will be binding upon any entity
       succeeding to the Company by merger, consolidation, or acquisition of all
       or substantially all of the Company's assets (a "change in control"). In
       the event of a change in control, the surviving entity may call all
       outstanding ("in the money") warrants upon thirty (30) days notice.

3.     ISSUE TAX. The issuance of certificates for Warrant Shares upon the
       exercise of this Warrant shall be made without charge to the Holder of
       this Warrant or such Warrant Shares for any issuance tax or other costs
       in respect thereof, provided that the Company shall not be required to
       pay any tax which may be payable in respect of any transfer involved in
       the issuance and delivery of any certificate in a name other than the
       Holder of this Warrant, or any tax due with respect to the resale of any
       Warrant Shares.

4.     NO RIGHTS OR LIABILITIES AS A SHAREHOLDER. This Warrant shall not entitle
       the Holder hereof to any voting rights or other rights as a shareholder
       of the Company. No provision of this Warrant, in the absence of
       affirmative action by the Holder hereof to purchase Warrant Shares, and
       no mere enumeration herein of the rights or privileges of the Holder
       hereof, shall give rise to any liability of such Holder for the Exercise
       Price or as a shareholder of the Company, whether such liability is
       asserted by the Company or by creditors of the Company.

6.     ANTIDILUTION PROVISIONS. After the initial issuance of this Warrant, the
       Exercise Price and the number of Warrant Shares shall be subject to
       adjustment from time to time as provided in this Section 6.

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

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


                                       3
<PAGE>   4

       reverse stock split, recapitalization, reorganization, reclassification
       or otherwise) its shares of Common Stock into a smaller number of shares,
       then, after the date of record for effecting such combination, the
       Exercise Price in effect immediately prior to such combination will be
       proportionately increased.

(b)    ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of the Exercise
       Price pursuant to the provisions of this Section 6, the number of shares
       of Common Stock issuable upon exercise of this Warrant shall be adjusted
       by multiplying a number equal to the Exercise Price in effect immediately
       prior to such adjustment by the number of shares of Common Stock issuable
       upon exercise of this Warrant immediately prior to such adjustment and
       dividing the product so obtained by the adjusted Exercise Price.

(c)    CONSOLIDATION, MERGER OR SALE. In case of any consolidation of the
       Company with, or merger of the Company into any other corporation, or in
       case of any sale or conveyance of all or substantially all of the assets
       of the Company other than in connection with a plan of complete
       liquidation of the Company at any time after the initial issuance of this
       Warrant, then adequate provision will be made in such transaction whereby
       the holder of this Warrant will have the right to acquire and receive
       upon exercise of this Warrant in lieu of the shares of Common Stock
       immediately theretofore acquirable upon the exercise of this Warrant,
       such shares of stock, securities or assets as may be issued or payable
       with respect to or in exchange for the number of shares of Common Stock
       immediately theretofore acquirable and receivable upon exercise of this
       Warrant had such consolidation, merger or sale or conveyance not taken
       place. In any such case, the Company will make appropriate provision to
       insure that the provisions of this Section 6 hereof will thereafter be
       applicable as nearly as may be in relation to any shares of stock or
       securities thereafter deliverable upon the exercise of this Warrant. The
       Company will not effect any consolidation, merger or sale or conveyance
       unless prior to the consummation thereof, the successor corporation (if
       other than the Company) assumes by written instrument the obligations
       under this Section 6 and the obligations to deliver to the holder of this
       Warrant such shares of stock, securities or assets as, in accordance with
       the foregoing provisions, the holder may be entitled to acquire.

(d)    DISTRIBUTION OF ASSETS. In case the Company shall declare or make any
       distribution of its assets (or rights to acquire its assets) to holders
       of Common Stock as a partial liquidating dividend, by way of return of
       capital or otherwise (including any dividend or distribution to the
       Company's shareholders of cash or shares (or rights to acquire shares) of
       capital stock of a subsidiary) (a "DISTRIBUTION"), at any time after the
       initial issuance of this Warrant, then the holder of this Warrant shall
       be entitled upon exercise of this Warrant for the purchase of any or all
       of the shares of Common Stock subject hereto, to receive the amount of
       such assets (or rights) which would have been payable to the holder had
       such holder been the holder of such shares of Common Stock on the record
       date for the determination of shareholders entitled to such Distribution.

(e)    NOTICE OF ADJUSTMENT. Upon the occurrence of any event which requires any
       adjustment of the Exercise Price, then, and in each such case, the
       Company shall give notice thereof to the holder of this Warrant, which
       notice shall state the Exercise Price resulting from such


                                       4
<PAGE>   5

       adjustment and the increase or decrease in the number of Warrant Shares
       purchasable at such price upon exercise, setting forth in reasonable
       detail the method of calculation and the facts upon which such
       calculation is based. Such calculation shall be certified by the chief
       financial officer of the Company.

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

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

(h)    NO ADJUSTMENT. Notwithstanding anything in this Section 6 to the
       contrary, no adjustment in the number of securities purchaseable on
       exercise of this Warrant shall be made with respect to dilution which
       would result from the issuance of Common Stock pursuant to the exercise
       of outstanding warrants or options or warrants or options which may be
       granted pursuant to an incentive plan of the Company, whether qualified
       or nonqualified and for the benefit of employers and non-employees.

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

       (i) the Company shall declare any dividend upon the Common Stock payable
in shares of stock of any class or make any other distribution (other than
dividends or distributions payable in cash out of retained earnings consistent
with the Company's past practices with respect to declaring dividends and making
distributions) to the holders of the Common Stock;

       (ii) there shall be any capital reorganization of the Company, or
reclassification of the Common Stock, or consolidation or merger of the Company
with or into, or sale of all or substantially all of its assets to, another
corporation or entity; or

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

then, in each such case, the Company shall give to the holder of this Warrant
(a) notice of the date on which the books of the Company shall close or a record
shall be taken for determining the holders of Common Stock entitled to receive
any such dividend, distribution, or subscription rights or for determining the
holders of Common Stock entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable approximation thereof by the
Company) when the same shall take place. Such notice shall also




                                       5
<PAGE>   6

specify the date on which the holders of Common Stock shall be entitled to
receive such dividend, distribution, or subscription rights or to exchange their
Common Stock for stock or other securities or property deliverable upon such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding-up, as the case may be. Such notice shall be given at
least 30 days prior to the record date or the date on which the Company's books
are closed in respect thereto; provided, however, that the Company shall not be
required to disclose any material information to the holder hereof prior to the
public disclosure thereof. Failure to give any such notice or any defect therein
shall not affect the validity of the proceedings referred to in clauses (i),
(ii), and (iii) above.

7.     TRANSFER, EXCHANGE, REDEMPTION AND REPLACEMENT OF WARRANT.

(a)    RESTRICTION ON TRANSFER. This Warrant and the rights granted to the
       Holder hereof are not transferable, in whole or in part, without the
       written consent of the Company, and delivery of the form of transfer
       attached hereto duly executed by the registered Holder hereof,

(b)    WARRANT EXCHANGEABLE FOR DIFFERENT DENOMINATIONS. This Warrant is
       exchangeable, upon the surrender hereof by the Holder hereof at the
       office or agency of the Company referred to in Section 6(e) below, for
       new Warrants of like tenor of different denominations representing in the
       aggregate the right to purchase the number of shares of Common Stock
       which may be purchased hereunder, each of such new Warrants to represent
       the right to purchase such number of shares as shall be designated by the
       Holder hereof at the time of such surrender.

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

(d)    CANCELLATION; PAYMENT OF EXPENSES. Upon the surrender of this Warrant in
       connection with any transfer, exchange, or replacement as provided in
       this Section 7, this Warrant shall be promptly canceled by the Company.
       The Warrant Holder shall pay all taxes (including securities transfer
       taxes) and all other expenses (including legal expenses, if any, incurred
       by the Holder, the Company or transferees) and charges payable in
       connection with the preparation, execution, and delivery of new Warrants
       pursuant to this Section 7(d).

(e)    WARRANT REGISTER. The Company shall maintain, at its principal executive
       offices (or such other office or agency of the Company as it may
       designate by notice to the Holder hereof), a register for this Warrant
       and all Warrants of like term, in which the Company shall record the name
       and address of the person in whose name this Warrant has been issued.

<PAGE>   7

8.          REGISTRATION OF WARRANT SHARES.

(a)    If the Company at any time or times proposes to register any of its
       securities under the Securities Act (other than a registration effected
       solely to implement an employee benefit plan or any other form or type of
       registration in which Warrant Shares cannot be included pursuant to
       Commission rule or practice), the Company will give written notice to the
       Holder of its intention to do so and such registration shall be governed
       by the terms and conditions of a certain Registration Rights Agreement of
       even date hereof between the Holder and the Company.

(b)    The Holder's right to require registration of the Warrant Shares under
       this Section 8, shall cease and terminate as to any particular Warrant
       Shares when such Warrant Shares shall have been effectively registered
       under the Securities Act in accordance with the Registration Rights
       Agreement. For purposes of this Warrant Certificate, shares of Common
       Stock issued hereunder shall also cease to be Warrant Shares when such
       shares have been sold to the public pursuant to an exemption from
       registration thereunder.

(c)    The Company covenants that it will, so long as any Warrant Shares or
       Warrants exercisable for Warrant Shares remain outstanding, file all
       reports required to be filed by it under the Securities Act and the
       Securities Exchange Act of 1934 and the rules and regulations promulgated
       by the Securities and Exchange Commission thereunder (or, if it is not
       required to file such reports , it will upon the request of any Holder
       make publicly available such information as will enable such Holder to
       sell such Warrant Shares without registration within the limitations of
       the exemptions provide by (i) Rule 144 promulgated under the Securities
       Act, as such rule may be amended from time to time, or (ii) any similar
       rule or regulation hereafter promulgated by the Securities Exchange
       Commission.

9.     NOTICES.

Any notices required or permitted to be given under the terms of this Warrant
shall be sent by certified or registered mail (return receipt requested) or
delivered personally or by courier or by confirmed telecopy, and shall be
effective five days after being placed in the mail, if mailed, or upon receipt
or refusal of receipt, if delivered personally or by courier or confirmed
telecopy, in each case addressed to a party. The addresses for such
communications shall be:

                        If to the Company:

and if to the Holder, at such address as such Holder shall have provided in
writing to the Company, or at such other address as each such party furnishes by
notice given in accordance with this Section 8. The Company may deem and treat
the registered Holder of this certificate as




                                       7
<PAGE>   8

the absolute owner of the Warrant Certificate for all purposes and shall not be
affected by any notice to the contrary.

10.    GOVERNING LAW. This Warrant Certificate shall be governed by and
       construed in accordance with the laws of the Commonwealth of Virginia
       without regard to its conflicts of laws rules as applied to contracts
       made and to be performed in the Commonwealth of Virginia.

11.    MISCELLANEOUS.

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

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

(c)    FORCE MAJEURE. Neither the Company nor the Holder hereof shall be
       responsible for any delay or failure to perform any part of this Warrant
       to the extent that such delay or failure is solely caused by fire, flood,
       earthquake, explosion, war, labor strike, riot, act of governmental,
       civil or military authority which imposes a moratorium on the performance
       of the specific obligation in question, failure of transfer agent, postal
       strike or other comparable extraordinary event beyond the Company's or
       Holder's control. Notice with full details of any such event shall be
       given to the other party as promptly as practicable after its occurrence.
       The affected party shall use its best efforts to minimize the effects of
       or end any such event so as to facilitate the resumption of full
       performance hereunder.

            IN WITNESS WHEREOF, the Company has caused this Warrant Certificate
to be signed by its duly authorized officer.

                           FORM OF EXERCISE AGREEMENT

         (TO BE EXECUTED BY THE HOLDER IN ORDER TO EXERCISE THE WARRANT)

            The undersigned hereby irrevocably exercises the right to purchase
_____________ shares of common stock of FastComm Communications Corporation, a
Virginia corporation (the "COMPANY"), evidenced by the attached Warrant
Certificate, and herewith makes payment of the Exercise Price with respect to
such shares, in full, all in accordance with the conditions and provisions of
said Warrant.

PRIVATE AND CONFIDENTIAL

Mr. Peter Madsen
Chairman & CEO
FastComm Communications Corporation
45472 Holiday Drive
Sterling, VA 20166

Dear Peter:

       This letter confirms that Kaufman Bros., L.P. ("Kaufman") has been
retained by FastComm Communications Corporation (the "Company") to act as the
Company's exclusive financial advisor in connection with the acquisition of
Cronus Communications, Inc. and Cronus Technology, Inc. (together, the
"Target").

A. Performance of Services

       Kaufman will provide the Company with investment banking and financial
advice in an attempt to identify, evaluate and negotiate a joint venture,
acquisition, merger, consolidation, reorganization, recapitalization, business
combination, purchase or sale of capital stock or assets outside the ordinary
course of business or other similar transaction (a "Transaction") during the
term of this agreement. Kaufman will assess the financial impact of the various
alternatives available to the Company, as well as examining the effects of any
proposed Transaction upon the Company and its shareholders. In addition, Kaufman
will evaluate offers and, to the extent deemed appropriate, assist and direct
negotiations leading to the conclusion of a Transaction.

B. Compensation for Services

       Merger Fee

       If during the term of this agreement or within one year thereafter the
Company enters into an acquisition, merger, consolidation, reorganization,
recapitalization or business combination with the Target, the Company will issue
to Kaufman 58,824 shares of the Company's restricted Common Stock (the
"Shares"). The Company will register all of the Shares with the SEC as soon as
practicable upon their issuance hereunder but in no event later than 120 days
after the Shares are due to Kaufman.

                                                                          Page 2


       Aggregate Consideration

       Aggregate Consideration is defined and computed as the total proceeds and
all other consideration received or receivable upon the consummation of a
transaction (including payments to be made in installments), including cash,
securities, notes, consulting agreements and agreements not to compete. If a
portion of such consideration includes escrowed or contingent payments (whether
or not related to future earnings of operations), Aggregate Consideration will
include such payments only when the conditions for the payment of such amounts
have been satisfied, at which time the Transaction Fee based thereon shall be
paid to Kaufman.

       Out-of-Pocket Expenses

       The Company will reimburse Kaufman for all reasonable out-of-pocket
expenses incurred in performance of this agreement without regard to whether a
Transaction is consummated.

C. Indemnification

       The Company shall indemnify Kaufman in accordance with Exhibit I attached
hereto.

D. Confidentiality

       Any financial or other advice, descriptive memoranda or other
documentation rendered by Kaufman pursuant to this agreement may not be
disclosed publicly or to any third party in any manner without the prior written
approval of Kaufman. All non-public information given to Kaufman by the Company
will be considered as confidential information and shall be maintained as such
by Kaufman until the same becomes known to third parties or the public without
release thereof by Kaufman. Kaufman may advertise the conclusion of a
Transaction in the financial press.

E. Engagement Period

       This engagement shall continue in effect until August 31, 2001 and shall
be automatically renewed for successive monthly periods until terminated in
writing by either the Company or Kaufman. The provisions of the paragraphs
regarding compensation, confidentiality and indemnification shall survive the
term of this Agreement.

       The Company acknowledges that Kaufman is and has been engaged as a
broker, dealer, underwriter, placement agent, finder, advisor, and dealmaker, by
and for other companies in the industry in which the Company is involved.
Accordingly, the Company agrees that Kaufman shall not be required to act
exclusively for the Company and may now and, from time to time in the future,
be engaged by other companies that compete with the Company. Kaufman may, but
shall not be required to bring opportunities to the Company.

                          EXHIBIT I -- INDEMNIFICATION

       The Company agrees that it will indemnify and hold harmless Kaufman, its
affiliates, control persons, officers, directors, employees and agents and each
person who controls Kaufman within the meaning of Section 15 of the Securities
Act of 1933 or Section 20 of the Securities Exchange Act (Kaufman and each such
entity and person being hereinafter called an "Indemnified Party") from and
against any and all losses, claims, damages, liabilities, costs or expenses
(including reasonable attorneys' and accountants' fees), as incurred, to which
such Indemnified Party may become subject which are (a) related to or arise out
of (i) actions taken or omitted to be taken (including any untrue statements
made or any statements omitted to be made) by the Company or (ii) actions taken
or omitted to be taken (including any untrue statements made or any statements
omitted to be made) by an Indemnified Party with the Company's consent or in
conformity with the instructions of, or actions taken or omitted to be taken by
the Company or (b) otherwise related to or arising out of Kaufman's acting
pursuant to this agreement. The Company also agrees to reimburse each
Indemnified Party within 30 days of submission of an invoice with respect
thereto for all expenses incurred (including fees and disbursements of counsel)
in connection with the investigation of or the preparation for or defense of any
pending or threatened formal or informal claim, action, investigation or other
proceeding caused by or arising out of or in connection with Kaufman's acting
pursuant to this agreement, whether or not Kaufman is a named party thereto and
whether or not any liability results therefrom. The Company will not be
responsible, however, for any loss, claim damage or liability for which
indemnification is sought solely pursuant to the first sentence of this
paragraph which a court of competent jurisdiction shall have determined by a
final judgment to have resulted primarily from willful misconduct or gross
negligence on the part of the Indemnified Party seeking indemnification
hereunder.

       Promptly after receipt by any Indemnified Party of notice of any
complaint or the commencement of any action or proceeding in connection with any
matter related to Kaufman's activities pursuant to the letter agreement, Kaufman
will notify the Company in writing of such complaint or of the commencement of
such action or proceeding and if the Company so elects or is requested by
Kaufman, the Company will assume the defense of such action or proceeding,
including the employment of counsel reasonably satisfactory to Kaufman and the
payment of the fees and disbursements of such counsel, in which event the
Company shall not be obligated to pay the fees and disbursements of separate
counsel for Kaufman in such action. However, failure by Kaufman to so notify the
Company of such claim or such commencement shall not relieve the Company from
any obligation hereunder except to the extent that such failure shall result in
prejudice to the Company. In the event, however, that Kaufman's legal counsel
shall determine that defenses may be available to an Indemnified Party that are
different from or in addition to those available to the Company or that there is
or could reasonably be expected to be a conflict of interest by reason of the
Company and an Indemnified Party having common counsel in any action or
proceeding, or if the Company has not assumed the defense of any action or
proceeding, then Kaufman may employ separate counsel to represent or defend it
or any Indemnified Party in any such action or proceeding in which it or such
Indemnified Party

                                                                          Page 5


may become involved or is named as defendant and the Company shall pay the fees
and disbursements, as Incurred by such separate counsel; provided that the
Company shall not be obligated to pay the fees and disbursements of more than
one such separate counsel for any one such action or proceeding in any one
jurisdiction.

       If for any reason the foregoing indemnification is unavailable to
Kaufman, or insufficient to hold it harmless, then the Company shall contribute
to the amount paid or payable by Kaufman as a result of such loss, claim, damage
or liability in such proportion as is appropriate to reflect the relative
benefits received by the Company and its stockholders on the one hand and
Kaufman on the other; provided that in no event will the aggregate contribution
by Kaufman hereunder exceed the amount of fees actually received by Kaufman
pursuant to this agreement. It is agreed that the relative benefit of the
Company on the one hand and of Kaufman on the other hand with respect to any
financing shall be deemed to be in the same proportion as (x) the Aggregate
Consideration paid or proposed to be paid in such financing (whether or not such
financing is consummated) bears (y) to the fee payable to Kaufman with respect
to such financing pursuant to this agreement.

       The reimbursement, indemnity and contribution obligations of the Company
under this paragraph shall be in addition to any liability which the Company may
otherwise have and shall be binding upon and inure to the benefit of any
successors, assigns, heirs and personal representatives of the Company, Kaufman
and any such person. The provisions of this Exhibit I shall survive the
termination and expiration of this agreement.

B. Compensation for Services

       Advisory Fee

       As compensation for its investment banking services, the Company agrees
to pay Kaufman a nonrefundable retainer fee of $5,000 upon the signing of this
letter, and four subsequent monthly installments of $5,000 each. In addition,
the Company will pay Kaufman upon signing of this letter, 200,000 warrants to

       Placement Fee

       If a Transaction is completed with any investor identified by Kaufman

or any future private financing within two years thereafter by such Target
Investor, the Company will pay Kaufman a placement fee equal to 5% of the gross
proceeds raised from the sale of securities to such Target Investor (the
"Placement Fee"); plus Warrants (as described above) equal to 5% of the shares
sold to such parties in the financing, at an exercise price equal to 120% of the

       The Placement Fee and Warrants will NOT be owed on any investment made by

public offering.

       Merger Fee

       If during the term of this agreement or within one year thereafter the
Company enters into a merger, consolidation, reorganization, recapitalization,
restructuring, tender or exchange offer, negotiated purchase, leveraged buyout,
partnership or collaborative venture whereby the Company's then existing
shareholders own less than 50% of the equity of the surviving entity, the
Company will pay Kaufman a fee equal to 2% of the Aggregate Consideration of the
completed transaction (the "Transaction Fee").

       Aggregate Consideration

       Aggregate Consideration is defined and computed as the total proceeds and
all other consideration received or receivable upon the consummation of a
transaction (including payments to be made in installments), including cash,

contingent payments (whether or not related to future earnings of operations),
Aggregate Consideration will include such payments only when the conditions for
the payment of such amounts have been satisfied, at which time the Transaction
Fee based thereon shall be paid to Kaufman.

       Out-of-Pocket Expenses

       The Company will reimburse Kaufman for all reasonable out-of-pocket
expenses incurred in performance of this agreement without regard to whether a
Transaction is consummated. Individual expenditures may not exceed $1,500
without the prior consent of the Company.

C. Rights of First Refusal

       The Company shall grant to Kaufman for a period of 18 months from the
date hereof, a first right of refusal to (i) co-manage any public offering of
the Company with any other underwriters of the Company's choosing provided that
Kaufman shall be entitled to at least 35% of the total compensation paid to the
underwriters in such a public offering; (ii) act as placement agent on any
future private financing of the Company; and (iii) to act as financial advisor

fees, will be covered under a letter of engagement separate from this letter.

disclosed publicly or to any third party in any manner without the prior written
approval of Kaufman which approval shall not be unreasonably withheld. All

any other material items. It is acknowledged and agreed that all information
provided to Kaufman is the property of the Company. The Company shall be solely

                          EXHIBIT I -- INDEMNIFICATION

       The Company agrees that it will indemnify and hold harmless Kaufman, its
affiliates, control persons, officers, directors, employees and agents and each
person who controls Kaufman within the meaning of Section 15 of the Securities
Act of 1933 or Section 20 of the Securities Exchange Act (Kaufman and each such
entity and person being hereinafter called an "Indemnified Party") from and
against any and all losses, claims, damages, liabilities, costs or expenses
(including reasonable attorneys' and accountants' fees), as incurred, to which
such Indemnified Party may become subject which are (a) related to or arise out
of (i) actions taken or omitted to be taken (including any untrue statements
made or any statements omitted to be made) by the Company or (ii) actions taken
or omitted to be taken (including any untrue statements made or any statements
omitted to be made) by an Indemnified Party with the Company's consent or in
conformity with the instructions of, or actions taken or omitted to be taken by
the Company or (b) otherwise related to or arising out of Kaufman's acting
pursuant to this agreement. The Company also agrees to reimburse each
Indemnified Party within 30 days of submission of an invoice with respect
thereto for all expenses incurred (including fees and disbursements of counsel)
in connection with the investigation of or the preparation for or defense of any
pending or threatened formal or informal claim, action, investigation or other
proceeding caused by or arising out of or in connection with Kaufman's acting
pursuant to this agreement, whether or not Kaufman is a named party thereto and
whether or not any liability results therefrom. The Company will not be
responsible, however, for any loss, claim damage or liability for which
indemnification is sought solely pursuant to the first sentence of this
paragraph which a court of competent jurisdiction shall have determined by a
final judgment to have resulted primarily from willful misconduct or gross
negligence on the part of the Indemnified Party seeking indemnification
hereunder.

       Promptly after receipt by any Indemnified Party of notice of any
complaint or the commencement of any action or proceeding in connection with any
matter related to Kaufman's activities pursuant to the letter agreement, Kaufman
will notify the Company in writing of such complaint or of the commencement of
such action or proceeding and if the Company so elects or is requested by
Kaufman, the Company will assume the defense of such action or proceeding,
including the employment of counsel reasonably satisfactory to Kaufman and the
payment of the fees and disbursements of such counsel, in which event the
Company shall not be obligated to pay the fees and disbursements of separate
counsel for Kaufman in such action. However, failure by Kaufman to so notify the
Company of such claim or such commencement shall not relieve the Company from
any obligation hereunder except to the extent that such failure shall result in
prejudice to the Company. In the event, however, that Kaufman's legal counsel
shall determine that defenses may be available to an Indemnified Party that are
different from or in addition to

those available to the Company or that there is or could reasonably be expected
to be a conflict of interest by reason of the Company and an Indemnified Party
having common counsel in any action or proceeding, or if the Company has not
assumed the defense of any action or proceeding, then Kaufman may employ
separate counsel to represent or defend it or any Indemnified Party in any such
action or proceeding in which it or such Indemnified Party may become involved
or is named as defendant and the Company shall pay the fees and disbursements,
as Incurred by such separate counsel; provided that the Company shall not be
obligated to pay the fees and disbursements of more than one such separate
counsel for any one such action or proceeding in any one jurisdiction.

       If for any reason the foregoing indemnification is unavailable to
Kaufman, or insufficient to hold it harmless, then the Company shall contribute
to the amount paid or payable by Kaufman as a result of such loss, claim, damage
or liability in such proportion as is appropriate to reflect the relative
benefits received by the Company and its stockholders on the one hand and
Kaufman on the other; provided that in no event will the aggregate contribution
by Kaufman hereunder exceed the amount of fees actually received by Kaufman
pursuant to this agreement. It is agreed that the relative benefit of the
Company on the one hand and of Kaufman on the other hand with respect to any
financing shall be deemed to be in the same proportion as (x) the Aggregate
Consideration paid or proposed to be paid in such financing (whether or not such
financing is consummated) bears (y) to the fee payable to Kaufman with respect
to such financing pursuant to this agreement.

       The reimbursement, indemnity and contribution obligations of the Company
under this paragraph shall be in addition to any liability which the Company may
otherwise have and shall be binding upon and inure to the benefit of any
successors, assigns, heirs and personal representatives of the Company, Kaufman
and any such person. The provisions of this Exhibit I shall survive the
termination and expiration of this agreement.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED. THESE SECURITIES MAY NOT BE OFFERED OR
SOLD IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION FROM REGISTRATION UNDER
SUCH ACT.

                         THE TRANSFER OF THIS WARRANT IS
                         RESTRICTED AS DESCRIBED HEREIN.

                       FASTCOMM COMMUNICATIONS CORPORATION

               Warrant for the Purchase of Shares of Common Stock,
                            par value $0.01 per Share


No. KB-1                                                          200,000 Shares


              THIS CERTIFIES that, for value received, KAUFMAN BROS., L.P., 800
Third Avenue - 25th Floor, New York, New York 10022 (the "Holder"), is entitled
to subscribe for and purchase from FASTCOMM COMMUNICATIONS CORPORATION, a
Delaware corporation (the "Company"), upon the terms and conditions set forth
herein, at any time or from time to time after February 1, 2000, and before 5:00
P.M. on January 31, 2003, New York time (the "Exercise Period"), 200,000 shares
of the Company's Common Stock, par value $0.01 per share ("Common Stock"), at a
price of $7.50 per share (the "Exercise Price"). As used herein the term "this
Warrant" shall mean and include this Warrant and any Common Stock or Warrants
hereafter issued as a consequence of the exercise or transfer of this Warrant in
whole or in part. This Warrant may not be sold, transferred, assigned or
hypothecated except that it may be transferred, in whole or in part, to (i) not
more that ten officers or partners of the Holder (or the officers or partners of
any such partner); (ii) a successor to the Holder, or the officers or partners
of such successor; (iii) a purchaser of substantially all of the assets of the
Holder; or (iv) by operation of law; and the term the "Holder" as used herein
shall include any transferee to whom this Warrant has been transferred in
accordance with the above.

              The number of shares of Common Stock issuable upon exercise of the
Warrant (the "Warrant Shares") and the Exercise Price may be adjusted from time
to time as hereinafter set forth.

              1.     This Warrant may be exercised during the Exercise Period,
as to the whole or any lesser number of whole Warrant Shares, by the surrender
of this Warrant (with the election at the end hereof duly executed) to the
Company at its office at 45472 Holiday Drive, Dulles, Virginia, 20166 or at such
other place as is designated in writing by the Company, together with a
certified or bank cashier's check payable to the order of the Company in an


<PAGE>   2


amount equal to the Exercise Price multiplied by the number of Warrant Shares
for which this Warrant is being exercised (the "Stock Purchase Price").

              2.     (a)    In lieu of the payment of the Stock Purchase Price,
       the Holder shall have the right (but not the obligation), to require the
       Company to convert this Warrant, in whole or in part, into shares of
       Common Stock (the "Conversion Right") as provided for in this Section 2.
       Upon exercise of the Conversion Right, the Company shall deliver to the
       Holder (without payment by the Holder of any of the Stock Purchase Price)
       that number of shares of Common Stock (the "Conversion Shares") equal to
       the quotient obtained by dividing (x) the value of this Warrant (or
       portion thereof as to which the Conversion Right is being exercised if
       the Conversion Right is being exercised in part) at the time the
       Conversion Right is exercised (determined by subtracting the aggregate
       Stock Purchase Price of the shares of Common Stock as to which the
       Conversion Right is being exercised in effect immediately prior to the
       exercise of the Conversion Right from the aggregate Current Market Price
       (as defined in Section 6(d) hereof) of the shares of Common Stock as to
       which the Conversion Right is being exercised) by (y) the Current Market
       Price of one share of Common Stock immediately prior to the exercise of
       the Conversion Right.

                     (b)    The Conversion Right provided under this Section 2
       may be exercised in whole or in part and at any time and from time to
       time while this Warrant remains outstanding. In order to exercise the
       Conversion Right, the Holder shall surrender to the Company, at its
       offices, this Warrant with the Notice of Conversion at the end hereof
       duly executed. The presentation and surrender shall be deemed a waiver of
       the Holder's obligation to pay all or any portion of the aggregate
       purchase price payable for the shares of Common Stock as to which such
       Conversion Right is being exercised. This Warrant (or so much thereof as
       shall have been surrendered for conversion) shall be deemed to have been
       converted immediately prior to the close of business on the day of
       surrender of such Warrant for conversion in accordance with the foregoing
       provisions.

              3.     Upon each exercise of the Holder's rights to purchase
Warrant Shares or Conversion Shares, the Holder shall be deemed to be the holder
of record of the Warrant Shares or Conversion Shares issuable upon such exercise
or conversion, notwithstanding that the transfer books of the Company shall then
be closed or certificates representing such Warrant Shares or Conversion Shares
shall not then have been actually delivered to the Holder. As soon as
practicable after each such exercise or conversion of this Warrant, the Company
shall issue and deliver to the Holder a certificate or certificates for the
Warrant Shares or Conversion Shares issuable upon such exercise or conversion,
registered in the name of the Holder or its designee. If this Warrant should be
exercised or converted in part only, the Company shall, upon surrender of this
Warrant for cancellation, execute and deliver a new Warrant evidencing the right
of the Holder to purchase the balance of the Warrant Shares (or portions
thereof) subject to purchase hereunder.


<PAGE>   3


              4.     Any Warrant issued upon the transfer or exercise or
conversion in part of this Warrant shall be numbered and shall be registered in
a Warrant Register as they are issued. The Company shall be entitled to treat
the registered holder of any Warrant on the Warrant Register as the owner in
fact thereof for all purposes and shall not be bound to recognize any equitable
or other claim to or interest in such Warrant on the part of any other person,
and shall not be liable for any registration or transfer of Warrants which are
registered or to be registered in the name of a fiduciary or the nominee of a
fiduciary unless made with the actual knowledge that a fiduciary or nominee is
committing a breach of trust in requesting such registration or transfer, or
with the knowledge of such facts that its participation therein amounts to bad
faith. This Warrant shall be transferable only on the books of the Company upon
delivery thereof duly endorsed by the Holder or by his duly authorized attorney
or representative, or accompanied by proper evidence of succession, assignment,
or authority to transfer. In all cases of transfer by an attorney, executor,
administrator, guardian, or other legal representative, duly authenticated
evidence of his or its authority shall be produced. Upon any registration of
transfer, the Company shall deliver a new Warrant or Warrants to the person
entitled thereto. This Warrant may be exchanged, at the option of the Holder
thereof, for another Warrant, or other Warrants of different denominations, of
like tenor and representing in the aggregate the right to purchase a like number
of Warrant Shares (or portions thereof), upon surrender to the Company or its
duly authorized agent. Notwithstanding the foregoing, the Company shall have no
obligation to cause Warrants to be transferred on its books to any person if, in
the opinion of counsel to the Company, such transfer does not comply with
applicable law, including without limitations, the provisions of the Securities
Act of 1933, as amended (the "Act"), and the rules and regulations thereunder
and any state securities laws or regulations.

              5.     The Company shall at all times reserve and keep available
out of its authorized and unissued Common Stock, solely for the purpose of
providing for the exercise of the rights to purchase all Warrant Shares and/or
Conversion Shares granted pursuant to this Warrant, such number of shares of
Common Stock as shall, from time to time, be sufficient therefor. The Company
covenants that all shares of Common Stock issuable upon exercise of this
Warrant, upon receipt by the Company of the full Exercise Price therefor, and
all shares of Common Stock issuable upon conversion of this Warrant, shall be
validly issued, fully paid, non-assessable, and free of preemptive rights.

              6.     (a)    In case the Company shall at any time after the date
       hereof (i) declare a dividend on the outstanding shares of Common Stock
       payable solely in the shares of its capital stock, (ii) subdivide the
       outstanding Common Stock, (iii) combine the outstanding Common Stock into
       a smaller number of shares, or (iv) issue any shares of its capital stock
       by reclassification of the Common Stock (including any such
       reclassification in connection with a consolidation or merger in which
       the Company is the continuing corporation), then, in each case, the
       Exercise Price, and the number and kind of securities issuable upon
       exercise or conversion of this Warrant, in effect at the time of the
       record date for such dividend or of the effective date of such
       subdivision, combination, or reclassification, shall be proportionately
       adjusted so that the Holder after such time shall be entitled to receive
       the aggregate number and kind of shares


<PAGE>   4


       which, if such Warrant had been exercised or converted immediately prior
       to such time, he would have owned upon such exercise or conversion and
       been entitled to receive by virtue of such dividend, subdivision,
       combination, or reclassification. Such adjustment shall be made
       successively whenever any event listed above shall occur.

                     (b)    In case the Company shall issue or fix a record date
       for the issuance to all holders of Common Stock of rights, options, or
       warrants to subscribe for or purchase Common Stock (or securities
       convertible into or exchangeable for Common Stock) at a price per share
       (or having a conversion or exchange price per share, if a security
       convertible into or exchangeable for Common Stock) less than the Current
       Market Price per share of Common Stock on such record date, then, in each
       case, the Exercise Price shall be adjusted by multiplying the Exercise
       Price in effect immediately prior to such record date by a fraction, the
       numerator of which shall be the number of shares of Common Stock
       outstanding on such record date plus the number of shares of Common Stock
       which the aggregate offering price of the total number of shares of
       Common Stock so to be offered (or the aggregate initial conversion or
       exchange price of the convertible or exchangeable securities so to be
       offered) would purchase at such Current Market Price and the denominator
       of which shall be the number of shares of Common Stock outstanding on
       such record date plus the number of additional shares of Common Stock to
       be offered for subscription or purchase (or into which the convertible or
       exchangeable securities so to be offered are initially convertible or
       exchangeable). Such adjustment shall become effective at the close of
       business on such record date; provided, however, that, to the extent the
       shares of Common Stock (or securities convertible into or exchangeable
       for shares of Common Stock) are not delivered, the Exercise Price shall
       be readjusted after the expiration of such rights, options, or warrants
       (but only with respect to Warrants exercised after such expiration), to
       the Exercise Price which would then be in effect had the adjustments made
       upon the issuance of such rights, options, or warrants been made upon the
       basis of delivery of only the number of shares of Common Stock (or
       securities convertible into or exchangeable for shares of Common Stock)
       actually issued. In case any subscription price may be paid in a
       consideration part or all of which shall be in a form other than cash,
       the value of such consideration shall be as determined in good faith by
       the board of directors of the Company, whose determination shall be
       conclusive absent manifest error. Shares of Common Stock owned by or held
       for the account of the Company or any majority-owned subsidiary shall not
       be deemed outstanding for the purpose of any such computation.

                     (c)    In case the Company shall distribute to all holders
       of Common Stock (including any such distribution made to the stockholders
       of the Company in connection with a consolidation or merger in which the
       Company is the continuing corporation) evidences of its indebtedness or
       assets (other than cash dividends or distributions and dividends payable
       in shares of Common Stock), or rights, options, or warrants to subscribe
       for or purchase Common Stock, or securities convertible into or
       exchangeable for shares of Common Stock (excluding those with respect to
       the issuance


<PAGE>   5


of which an adjustment of the Exercise Price is provided pursuant to Section
6(b) hereof), then, in each case, the Exercise Price shall be adjusted by
multiplying the Exercise Price in effect immediately prior to the record date
for the determination of stockholders entitled to receive such distribution by a
fraction, the numerator of which shall be the Current Market Price per share of
Common Stock on such record date, less the fair market value (as determined in
good faith by the board of directors of the Company, whose determination shall
be conclusive absent manifest error) of the portion of the evidences of
indebtedness or assets so to be distributed, or of such rights, options, or
warrants or convertible or exchangeable securities, applicable to one share, and
the denominator of which shall be such Current Market Price per share of Common
Stock. Such adjustment shall be made whenever any such distribution is made, and
shall become effective on the record date for the determination of stockholders
entitled to receive such distribution.

              (d)    For the purpose of any computation under this Section 6,
the Current Market Price per share of Common Stock on any date shall be
deemed to be the average of the daily closing prices for the 30 consecutive
trading days immediately preceding the date in question. The closing price for
each day shall be the last reported sales price regular way or, in case no such
reported sale takes place on such day, the closing bid price regular way, in
either case on the principal national securities exchange (including, for
purposes hereof, the NASDAQ SmallCap Market) on which the Common Stock is listed
or admitted to trading or, if the Common Stock is not listed or admitted to
trading on any national securities exchange, the highest reported bid price for
the Common Stock as furnished by the National Association of Securities Dealers,
Inc. through NASDAQ or a similar organization if NASDAQ is no longer reporting
such information. If on any such date the Common Stock is not listed or admitted
to trading on any national securities exchange and is not quoted by NASDAQ or
any similar organization, the fair value of a share of Common Stock on such
date, as determined in good faith by the board of directors of the Company,
whose determination shall be conclusive absent manifest error, shall be used.

              (e)    No adjustment in the Exercise Price shall be required if
such adjustment is less than $.05; provided, however, that any adjustments which
by reason of this Section 6 are not required to be made shall be carried forward
and taken into account in any subsequent adjustment. All calculations under this
Section 6 shall be made to the nearest cent or to the nearest one-thousandth of
a share, as the case may be.

              (f)    In any case in which this Section 6 shall require that an
adjustment in the Exercise Price be made effective as of a record date for a
specified event, the Company may elect to defer, until the occurrence of such
event, issuing to the Holder, if the Holder exercised or converted this Warrant
after such record date, the shares of Common Stock, if any, issuable upon such
exercise or conversion over and above the shares of Common Stock, if any,
issuable upon such exercise or conversion on the basis of the Exercise Price in
effect prior to such adjustment; provided, however,


<PAGE>   6



that the Company shall deliver to the Holder a due bill or other appropriate
instrument evidencing the Holder's right to receive such additional shares upon
the occurrence of the event requiring such adjustment.

              (g)    Upon each adjustment of the Exercise Price as a result of
the calculations made in Sections 6(b) or 6(c) hereof, this Warrant shall
thereafter evidence the right to purchase, at the adjusted Exercise Price, that
number of shares (calculated to the nearest thousandth) obtained by dividing (i)
the product obtained by multiplying the number of shares purchasable upon
exercise of this Warrant prior to adjustment of the number of shares by the
Exercise Price in effect prior to adjustment of the Exercise Price, by (ii) the
Exercise Price in effect after such adjustment of the Exercise Price.

              (h)    Whenever there shall be an adjustment as provided in this
Section 6, the Company shall promptly cause written notice thereof to be sent by
registered mail, postage prepaid, to the Holder, at its address as it shall
appear in the Warrant Register, which notice shall be accompanied by an
officer's certificate setting forth the number of Warrant Shares purchasable
upon the exercise of this Warrant and the Exercise Price after such adjustment
and setting forth a brief statement of the facts requiring such adjustment and
the computation thereof, which officer's certificate shall be conclusive
evidence of the correctness of any such adjustment absent manifest error.

              (j)    The Company shall not be required to issue fractions of
shares of Common Stock or other capital stock of the Company upon the exercise
or conversion of this Warrant. If any fraction of a share would be issuable on
the exercise or conversion of this Warrant (or specified portions thereof), the
Company shall purchase such fraction for an amount in cash equal to the same
fraction of the Current Market Price of such share of Common Stock on the date
of exercise or conversion of this Warrant.

       7.     (a)    In case of any consolidation with or merger of the Company
with or into another corporation (other than a merger or consolidation in which
the Company is the surviving or continuing corporation), or in case of any sale,
lease, or conveyance to another corporation of the property and assets of any
nature of the Company as an entirety or substantially as an entirety, such
successor, leasing, or purchasing corporation, as the case may be, shall (i)
execute with the Holder an agreement providing that the Holder shall have the
right thereafter to receive upon exercise or conversion of this Warrant solely
the kind and amount of shares of stock and other securities, property, cash, or
any combination thereof receivable upon such consolidation, merger, sale, lease,
or conveyance by a holder of the number of shares of Common Stock for which this
Warrant might have been exercised or converted immediately prior to such
consolidation, merger, sale, lease, or conveyance, and (ii) make effective
provision in its certificate of incorporation or otherwise, if necessary, to
effect such agreement. Such agreement shall provide for adjustments which shall
be as nearly equivalent as practicable to the adjustments in Section 6.


<PAGE>   7




              (b)    In case of any reclassification or change of the shares of
Common Stock issuable upon exercise or conversion of this Warrant (other than a
change in par value or from no par value to a specified par value, or as a
result of a subdivision or combination, but including any change in the shares
into two or more classes or series of shares), or in case of any consolidation
or merger of another corporation into the Company in which the Company is the
continuing corporation and in which there is a reclassification or change
(including a change to the right to receive cash or other property) of the
shares of Common Stock (other than a change in par value, or from no par value
to a specified par value, or as a result of a subdivision or combination, but
including any change in the shares into two or more classes or series of
shares), the Holder shall have the right thereafter to receive upon exercise or
conversion of this Warrant solely the kind and amount of shares of stock and
other securities, property, cash, or any combination thereof receivable upon
such reclassification, change, consolidation, or merger by a holder of the
number of shares of Common Stock for which this Warrant might have been
exercised or converted immediately prior to such reclassification, change,
consolidation, or merger. Thereafter, appropriate provision shall be made for
adjustments which shall be as nearly equivalent as practicable to the
adjustments in Section 6.

              (c)    The above provisions of this Section 7 shall similarly
apply to successive reclassifications and changes of shares of Common Stock and
to successive consolidations, mergers, sales, leases, or conveyances.

       8.     In case at any time the Company shall propose

              (a)    to pay any dividend or make any distribution on shares of
Common Stock in shares of Common Stock or make any other distribution (other
than regularly scheduled cash dividends which are not in a greater amount per
share than the most recent such cash dividend) to all holders of Common Stock;
or

              (b)    to issue any rights, warrants, or other securities to all
holders of Common Stock entitling them to purchase any additional shares of
Common Stock or any other rights, warrants, or other securities; or

              (c)    to effect any reclassification or change of outstanding
shares of Common Stock, or any consolidation, merger, sale, lease, or conveyance
of property, described in Section 7; or

              (d)    to effect any liquidation, dissolution, or winding-up of
the Company; or

              (e)    to take any other action which would cause an adjustment to
the Exercise Price;


<PAGE>   8



then, and in any one or more of such cases, the Company shall give written
notice thereof, by registered mail, postage prepaid, to the Holder at the
Holder's address as it shall appear in the Warrant Register, mailed at least 15
days prior to (i) the date as of which the holders of record of shares of Common
Stock to be entitled to receive any such dividend, distribution, rights,
warrants, or other securities are to be determined, (ii) the date on which any
such reclassification, change of outstanding shares of Common Stock,
consolidation, merger, sale, lease, conveyance of property, liquidation,
dissolution, or winding-up is expected to become effective, and the date as of
which it is expected that holders of record of shares of Common Stock shall be
entitled to exchange their shares for securities or other property, if any,
deliverable upon such reclassification, change of outstanding shares,
consolidation, merger, sale, lease, conveyance of property, liquidation,
dissolution, or winding-up, or (iii) the date of such action which would require
an adjustment to the Exercise Price.

              9.     The issuance of any shares or other securities upon the
exercise or conversion of this Warrant, and the delivery of certificates or
other instruments representing such shares or other securities, shall be made
without charge to the Holder for any tax or other charge in respect of such
issuance. The Company shall not, however, be required to pay any tax which may
be payable in respect of any transfer involved in the issue and delivery of any
certificate in a name other than that of the Holder and the Company shall not be
required to issue or deliver any such certificate unless and until the person or
persons requesting the issue thereof shall have paid to the Company the amount
of such tax or shall have established to the satisfaction of the Company that
such tax has been paid.

              10.   (a)     If, at any time prior to February 1, 2003, while any
       Warrant or Warrant Shares are outstanding, the Company shall file a
       registration statement with the Securities and Exchange Commission (the
       "Commission") to register the sale any of its equity securities for its
       own account (and not for the account of a security holder or holders) for
       cash, other than (w) a registration relating to employee benefit plans,
       (x) a registration relating to a corporate reorganization or other
       transaction under Rule 145, (y) a registration relating to the Company's
       equity line of credit with Cambois Finance, Inc., or (z) a registration
       on any registration form that does not permit secondary sales, the
       Company shall give the Holder at least 15 days prior written notice of
       the filing of such registration statement. If requested by the Holder in
       writing within 10 days after receipt of any such notice, the Company
       shall, at the Company's sole expense (other than the fees and
       disbursements of counsel for the Holder and the underwriting discounts,
       if any, payable in respect of the Warrant Shares sold by the Holder),
       register or qualify all or, at the Holders' option, any portion of the
       Warrant Shares of the Holder concurrently with the registration of such
       other securities, all to the extent requisite to permit the public
       offering and sale of the Warrant Shares through the facilities of all
       appropriate securities exchanges and the over-the-counter market. As a
       condition to the registration of any Warrant Shares in an underwritten
       public offering, the Holder shall (together with the Company and the
       other holders of securities of the Company with registration rights to
       participate therein distributing their securities through such


<PAGE>   9


underwriting) enter into an underwriting agreement in customary form with the
representative of the underwriter or underwriters selected by the Company.
Notwithstanding the foregoing, if the representative of the underwriter or
underwriters of any such offering shall advise the Company in writing that, in
its opinion, the distribution of all or a portion of the Warrant Shares
requested to be included in the registration concurrently with the securities
being registered by the Company would adversely affect the distribution of such
securities by the Company for its own account, the number of shares that may be
included in such registration in such offering shall be allocated as follows:
(i) first, the Company shall be permitted to include all shares of capital stock
to be registered thereby and (ii) second, the Holder shall be allowed to include
such additional amount as the lead managing underwriter deems appropriate, such
amount to be allocated among such Holder and any other selling stockholders on a
pro rata basis based on the total number of shares of capital stock held
thereby. As used herein, "Warrant Shares" shall mean the Warrant Shares and the
Conversion Shares which, in each case, have not been previously sold pursuant to
a registration statement or Rule 144 promulgated under the Act.

              (b)    In the event of a registration pursuant to the provisions
of this Section 10, the Company shall use its best efforts to cause the Warrant
Shares so registered to be registered or qualified for sale under the securities
or blue sky laws of such jurisdictions as the Holder may reasonably request;
provided, however, that the Company shall not be required to qualify to do
business in any state by reason of this Section 10(b) in which it is not
otherwise required to qualify to do business.

              (c)    The Company shall keep effective any registration or
qualification contemplated by this Section 10 and shall from time to time amend
or supplement each applicable registration statement, preliminary prospectus,
final prospectus, application, document, and communication for such period of
time as shall be required to permit the Holder to complete the offer and sale of
the Warrant Shares covered thereby. The Company shall in no event be required to
keep any such registration or qualification in effect for a period in excess of
90 days from the date on which the Holder is first free to sell such Warrant
Shares; provided, however, that, if the Company is required to keep any such
registration or qualification in effect with respect to securities other than
the Warrant Shares beyond such period, the Company shall keep such registration
or qualification in effect as it relates to the Warrant Shares for so long as
such registration or qualification remains or is required to remain in effect in
respect of such other securities.

              (d)    In the event of a registration pursuant to the provisions
of this Section 10, the Company shall furnish to the Holder such number of
copies of the registration statement and of each amendment and supplement
thereto (in each case, including all exhibits), such reasonable number of copies
of each prospectus contained in such registration statement and each supplement
or amendment thereto (including each preliminary prospectus), all of which shall
conform to the requirements of the Act


<PAGE>   10


and the rules and regulations thereunder, and such other documents, as the
Holder may reasonably request to facilitate the disposition of the Warrant
Shares included in such registration.

              (e)    In the event of a registration pursuant to the provisions
of this Section 10, the Company shall furnish the Holder so registered with an
opinion of its counsel covering such matters as are customarily the subject of
opinions of issuer's counsel provided to underwriters in underwritten public
offerings.

              (f)    The Company agrees that until the Warrant has expired or
all of the Warrant Shares have been sold under a registration statement or
pursuant to Rule 144 under the Act, it shall keep current in filing all reports,
statements and other materials required to be filed with the Commission to
permit the Holder to sell the Warrant Shares under Rule 144.

       11.    (a)    Subject to the conditions set forth below, the Company
agrees to indemnify and hold harmless the Holder, its officers, directors,
partners, employees, agents, and counsel, and each person, if any, who controls
any such person within the meaning of Section 15 of the Act or Section 20(a) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), from and
against any and all loss, liability, charge, claim, damage, and expense
whatsoever (which shall include, for all purposes of this Section 11, but not be
limited to, attorneys' fees and any and all reasonable expense whatsoever
incurred in investigating, preparing, or defending against any litigation,
commenced or threatened, or any claim whatsoever, and any and all amounts paid
in settlement of any claim or litigation), as and when incurred, arising out of,
based upon, or in connection with (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in any registration statement,
preliminary prospectus, or final prospectus (as from time to time amended and
supplemented), or any amendment or supplement thereto, relating to the sale of
the Warrant Shares, or (B) in any application or other document or communication
(in this Section 11 collectively called an "application") executed by or on
behalf of the Company or based upon written information furnished by or on
behalf of the Company filed in any jurisdiction in order to register or qualify
any of the Warrant Shares under the securities or blue sky laws thereof or filed
with the Commission or any securities exchange; or any omission or alleged
omission to state a material fact required to be stated therein or necessary to
make the statements therein not misleading, unless such statement or omission
was made in reliance upon and in conformity with written information furnished
to the Company with respect to the Holder by or on behalf of the Holder
expressly for inclusion in any registration statement, preliminary prospectus,
or final prospectus, or any amendment or supplement thereto, or in any
application, as the case may be, or (ii) any breach of any representation,
warranty, covenant, or agreement of the Company contained in this Warrant. The
foregoing agreement to indemnify shall be in addition to any liability the
Company may otherwise have, including liabilities arising under this Warrant.


<PAGE>   11



       If any action is brought against the Holder or any of its officers,
directors, partners, employees, agents, or counsel, or any controlling persons
of such person (an "indemnified party") in respect of which indemnity may be
sought against the Company pursuant to the foregoing paragraph, such indemnified
party or parties shall promptly notify the Company in writing of the institution
of such action (but the failure so to notify shall not relieve the Company from
any liability pursuant to this Section 11(a) except to the extent that such
failure shall result in prejudice to the Company) and the Company shall promptly
assume the defense of such action, including the employment of counsel
(reasonably satisfactory to such indemnified party or parties) and payment of
expenses. Such indemnified party or parties shall have the right to employ its
or their own counsel in any such case, but the fees and expenses of such counsel
shall be at the expense of such indemnified party or parties unless the
employment of such counsel shall have been authorized in writing by the Company
in connection with the defense of such action or the Company shall not have
promptly employed counsel reasonably satisfactory to such indemnified party or
parties to have charge of the defense of such action or such indemnified party
or parties shall have reasonably concluded that there may be one or more legal
defenses available to it or them or to other indemnified parties which are
different from or additional to those available to the Company, in any of which
events such fees and expenses shall be borne by the Company and the Company
shall not have the right to direct the defense of such action on behalf of the
indemnified party or parties. The Company shall not be obligated to pay the fees
and expenses of more than one such separate counsel for any one such action or
proceeding in any one jurisdiction. Anything in this Section 11 to the contrary
notwithstanding, the Company shall not be liable for any settlement of any such
claim or action effected without its written consent, which shall not be
unreasonably withheld. The Company shall not, without the prior written consent
of each indemnified party that is not released as described in this sentence,
settle or compromise any action, or permit a default or consent to the entry of
judgment in or otherwise seek to terminate any pending or threatened action, in
respect of which indemnity may be sought hereunder (whether or not any
indemnified party is a party thereto), unless such settlement, compromise,
consent, or termination includes an unconditional release of each indemnified
party from all liability in respect of such action. The Company agrees promptly
to notify the Holder of the commencement of any litigation or proceedings
against the Company or any of its officers or directors in connection with the
sale of any Warrant Shares or any preliminary prospectus, prospectus,
registration statement, or amendment or supplement thereto, or any application
relating to any sale of any Warrant Shares.

              (b)    The Holder agrees to indemnify and hold harmless the
Company, each director of the Company, each officer of the Company who shall
have signed any registration statement covering Warrant Shares held by the
Holder, each other person, if any, who controls the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act, and its or their
respective counsel, to the same extent as the foregoing indemnity from the
Company to the Holder in Section 11(a), but only with


<PAGE>   12


respect to statements or omissions, if any, made in any registration statement,
preliminary prospectus, or final prospectus (as from time to time amended and
supplemented), or any amendment or supplement thereto, or in any application, in
reliance upon and in conformity with written information furnished to the
Company by or on behalf of the Holder expressly for inclusion in any such
registration statement, preliminary prospectus, or final prospectus, or any
amendment or supplement thereto, or in any application, as the case may be. If
any action shall be brought against the Company or any other person so
indemnified based on any such registration statement, preliminary prospectus, or
final prospectus, or any amendment or supplement thereto, or in any application,
and in respect of which indemnity may be sought against the Holder pursuant to
this Section 11(b), the Holder shall have the rights and duties given to the
Company, and the Company and each other person so indemnified shall have the
rights and duties given to the indemnified parties, by the provisions of Section
11(a).

              (c)    To provide for just and equitable contribution, if (i) an
indemnified party makes a claim for indemnification pursuant to Section 11(a) or
11(b) (subject to the limitations thereof) but it is found in a final judicial
determination, not subject to further appeal, that such indemnification may not
be enforced in such case, even though this Agreement expressly provides for
indemnification in such case, or (ii) any indemnified or indemnifying party
seeks contribution under the Act, the Exchange Act or otherwise, then the
Company (including for this purpose any contribution made by or on behalf of any
director of the Company, any officer of the Company who signed any such
registration statement, any controlling person of the Company, and its or their
respective counsel), as one entity, and the Holder (including for this purpose
any contribution by or on behalf of an indemnified party), as a second entity,
shall contribute to the losses, liabilities, claims, damages, and expenses
whatsoever to which any of them may be subject, on the basis of relevant
equitable considerations such as the relative fault of the Company and such
Holder in connection with the facts which resulted in such losses, liabilities,
claims, damages, and expenses. The relative fault, in the case of an untrue
statement, alleged untrue statement, omission, or alleged omission, shall be
determined by, among other things, whether such statement, alleged statement,
omission, or alleged omission relates to information supplied by the Company or
by such Holder, and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement, alleged
statement, omission, or alleged omission. The Company and the Holder agree that
it would be unjust and inequitable if the respective obligations of the Company
and the Holder for contribution were determined by pro rata or per capita
allocation of the aggregate losses, liabilities, claims, damages, and expenses
(even if the Holder and the other indemnified parties were treated as one entity
for such purpose) or by any other method of allocation that does not reflect the
equitable considerations referred to in this Section 11(c). In no case shall the
Holder be responsible for a portion of the contribution obligation imposed on it
in excess of its pro rata share based on the number of shares of Common Stock
owned (or which would be owned upon exercise of all Warrant or Warrant Shares)
by it and included in such registration as compared to the total number of
shares of Common

<PAGE>   13


       Stock included in such registration. No person guilty of a fraudulent
       misrepresentation (within the meaning of Section 11(f) of the Act) shall
       be entitled to contribution from any person who is not guilty of such
       fraudulent misrepresentation. For purposes of this Section 11(c), each
       person, if any, who controls the Holder within the meaning of Section 15
       of the Act or Section 20(a) of the Exchange Act and each officer,
       director, partner, employee, agent, and counsel of each such Holder or
       control person shall have the same rights to contribution as such Holder
       or control person and each person, if any, who controls the Company
       within the meaning of Section 15 of the Act or Section 20(a) of the
       Exchange Act, each officer of the Company who shall have signed any such
       registration statement, each director of the Company, and its or their
       respective counsel shall have the same rights to contribution as the
       Company, subject in each case to the provisions of this Section 11(c).
       Anything in this Section 11(c) to the contrary notwithstanding, no party
       shall be liable for contribution with respect to the settlement of any
       claim or action effected without its written consent. This Section 11(c)
       is intended to supersede any right to contribution under the Act, the
       Exchange Act or otherwise.

              12.    Unless registered pursuant to the provisions of Section 10
hereof, the Warrant Shares or Conversion Shares issued upon exercise or
conversion of the Warrants shall be subject to a stop transfer order and the
certificate or certificates evidencing such Warrant Shares shall bear the
following legend:

       "THE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
       OR QUALIFIED UNDER THE SECURITIES LAWS OF ANY STATE. THESE SECURITIES
       CANNOT BE SOLD OR TRANSFERRED WITHOUT SUCH REGISTRATION AND QUALIFICATION
       UNLESS AN EXEMPTION FROM SUCH REGISTRATION AND QUALIFICATION IS AVAILABLE
       AND THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE
       COMPANY TO THAT EFFECT."

              13.    Upon receipt of evidence satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant (and upon surrender of
this Warrant if mutilated), and upon reimbursement of the Company's reasonable
incidental expenses, the Company shall execute and deliver to the Holder thereof
a new Warrant of like date, tenor, and denomination.

              14.    The Holder shall not have, solely on account of such
status, any rights of a stockholder of the Company, either at law or in equity,
or to any notice of meetings of stockholders or of any other proceedings of the
Company, except as provided in this Warrant.

              15.    This Warrant shall be construed in accordance with the laws
of the State of New York applicable to contracts made and performed within such
State, without regard to principles of conflicts of law.


<PAGE>   14




              16.    The Company irrevocably consents to the jurisdiction of the
courts of the federal courts located in the City of New York in connection with
any action or proceeding arising out of or relating to this Warrant, any
document or instrument delivered pursuant to, in connection with or
simultaneously with this Warrant, or a breach of this Warrant or any such
document or instrument. In any such action or proceeding, the Company waives
personal service of any summons, complaint or other process and agrees that
service thereof may be made by registered mail, return receipt requested. Within
30 days after such service, or such other time as may be mutually agreed upon in
writing by the attorneys for the parties to such action or proceeding, the
Company shall appear to answer such summons, complaint or other process. Should
the Company so served fail to appear or answer within such 30-day period or such
extended period, as the case may be, the Company shall be deemed in default and
judgment may be entered against the Company for the amount as demanded in any
summons, complaint or other process so served. The Company and Holder (by
Holder's acceptance of this Warrant) agree that if any action or proceeding is
brought to construe or enforce the terms and conditions of this Warrant or the
rights of the parties hereunder, the losing party shall pay to the prevailing
party all court costs and reasonable attorneys' fees and costs (at the
prevailing party's attorneys then-current rates) incurred in such action or
proceeding. A party that voluntarily dismisses an action or proceeding shall be
considered a losing party for purposes of this provision.
