Price shall be adjusted at the Closing so that the number of NuTech shares
delivered to Escrow at Closing shall be reduced by a sum determined by
multiplying the total aggregate amount of account receivables as set forth on
the Receivables List by fifty (50%) percent. For purposes hereof, each NuTech
share shall be valued at the Closing Market Value.

         (d) Establishment of Escrow. The Preliminary Purchase Price shall be

Agreement. The parties recognize and agree that the Escrow has been established
to provide assurance to Nu-Tech and NTBM Billing that Primary Customer provides

NTBM Billing during the Escrow Period at a level not less then the level
provided in Section 2(e) hereof except as otherwise provided herein.

                  (i) The Escrow shall remain in effect until a date which is
the earlier of: (i) two years from the Closing Date or (ii) the date on which
all cash and Nu-Tech Shares are released from Escrow ("Escrow Period)". Subject
to Section 2(e) below, the cash portion of the Preliminary Purchase Price shall
be released from Escrow and delivered to Prompt Medical, or in the event Prompt
Medical assigns its rights to payment from the Escrow to the PM Shareholders, to
the PM Shareholders (for purposes hereof, Prompt Medical or the PM Shareholders
constituting the "Escrow Payee") in eight (8) equal quarterly installments (of
90 days each) on the last day of each such quarterly period commencing 90 days
from the Closing Date. Each cash payment released from Escrow shall be in the
amount of $12,500 together with interest thereon. None of the Nu-Tech Shares
shall be released from Escrow until termination of the Escrow Period. Subject to
any adjustments required herein, the Nu-Tech Shares shall be released from
Escrow within five (5) business days of the termination of the Escrow Period.

                  (ii) If there is no dispute between the Parties with respect
to releasing the cash from Escrow, payment (each an "Escrow Payment") to the
Escrow Payee shall be made by the Escrow Agent two business days after the last
day of each quarter (each an "Escrow Payment Date") without further action or
notice from the parties (except as notice may be required by the Escrow Agent).
In the event that the Preliminary Purchase Price is subject to adjustment as
determined in accordance with Section 2(e) below or Section 8(f) herein, Nu-Tech
shall deliver a written notice (the "Adjustment Notice") to the Escrow Payee and
the Escrow Agent at least five (5) business days prior to the next Escrow
Payment Date, which notice shall state the amount of the proposed adjustment and
state in reasonable detail the reason for the proposed adjustment to the
Preliminary Purchase Price. If the Escrow Payee disagrees with the Adjustment
Notice, then within 10 business days of receipt of the Adjustment Notice, the
Escrow Payee shall deliver to Nu-Tech a written response ("Response Notice")
which shall provide in reasonable detail the basis of its disagreement. Pending
resolution of the dispute between the Parties, no payment shall be made from
Escrow; provided, however, notwithstanding the foregoing, any portion of an
Escrow Payment or any portion of the Nu-Tech Shares otherwise payable or
deliverable to the Escrow Payee and not then in dispute, including, without
limitation, all amounts in excess of the amount in dispute as set forth in the

Adjustment Notice, shall be released from Escrow and paid or delivered to the
Escrow Payee. In order to resolve any dispute, the Parties shall meet within 10
business days in Miami, Florida or such other location as shall be mutually
agreeable. In the event the Parties are unable to resolve such dispute within 30
days of such meeting, then the dispute shall be submitted to arbitration in
accordance with Section 11(p) hereof.

         (e) Post-Closing Adjustment for Customer Revenue.

                  (i) At Closing, the PM Shareholders and Prompt Medical shall
provide to Nu-Tech a detailed accounting of the Pre-Closing Primary Customer
Revenues (the "Primary Customer Revenue Statement"). The Primary Customer
Revenue Statement shall set forth (i) all fees earned by Prompt-Medical from
Primary Customer and (ii) all expenses charged to Prompt Medical by Primary
Customer with respect to personnel, computer, office space and general expenses.
The Primary Customer Revenue Statement shall be certified by each of the PM
Shareholders and be prepared in accordance with GAAP.

                  (ii) The Preliminary Purchase Price shall be subject to
adjustment in the event that the average annual Post-Closing Primary Customer
Revenue is less (a "Revenue Deficiency") than the higher of (a) the Pre-Closing
Primary Customer Revenue as set forth on the Primary Customer Revenue Statement
or (b) $185,000 (as applicable, the amount set forth herein under (a) or (b)
shall be referred to as the "Target Revenue"); provided, however, there shall be
no adjustment to the Preliminary Purchase Price in the event and to the extent
that revenue to NTBM Billing from Primary Customer during the Escrow Period is
less than the Target Revenue (X) as a result of changes in Medicare and/or
Medicaid and/or other third party payors reimbursement levels or (Y) to the
extent NTBM Billing obtains new business between June 30, 1996 and the end of
the Escrow Period and such new business is the direct result of efforts by the
PM Shareholders or (Z) as a result of increases in the expenses in the operation
of NTBM Billing's business as set forth in clause 2(e)(iii) below. In the event
that there is a Revenue Deficiency, then the number of Nu-Tech Shares otherwise
deliverable to the Escrow Payee from Escrow in accordance with Section 2(d)
above, shall be reduced by a corresponding amount equal to such Revenue
Deficiency. For purposes of this Section 2(e), each Nu-Tech Share shall be
valued at the Nu-Tech Share Closing Value (adjusted for any forward or reverse
stock split by Nu-Tech at any time during the Escrow Period). No fractional
shares shall be issued to Nu-Tech or the Escrow Payee and all shares shall be
rounded down to the nearest full share.

                                       14
   15
                  (iii) For purposes of determining adjustments to the
Preliminary Purchase Price as set forth in clause (ii) above, there shall be no
adjustments in the Preliminary Purchase Price in the event and to the extent
that there are increases in expenses deducted by the Primary Customer from NTBM
Billing's fees billed to the Primary Customer during the Escrow Period resulting
from increases in (i) personal costs (including, without limitation, costs
associated with the number of employees, their hours of employment and rates or
increases in salaries) which are approved in advance by NTBM Billing or fringe
benefit costs which NTBM Billing acknowledges are not subject to prior approval
by NTBM Billing, (ii) computer expenses provided that such computer expenses are
at the same pro-rata rate paid by Primary Customer to its computer company or
are specifically for billing and are paid at the rate charged to the Primary
Customer by the computer company unless approved in advance by NTBM Billing,
(iii) office space expenses (including expenses charged to NTBM Billing for
office space and pro rata share of water, taxes, electric, maintenance and sewer
charges related to such office space) which increases shall not exceed 10% per
annum unless approved in advance by NTBM Billing or unless expenses for items
such as water, sewer, electric or taxes or other third party charges which are
passed through to NTBM Billing due to no control of NTBM Billing or Primary
Customer and (iv) general expenses (including, without limitations, telephone,
postage office supply, copier and facsimile equipment repair and related
expenses) which increases shall not exceed 10% per annum unless approved in
advance by NTBM Billing.

         (f) Adjustment For Change in Nu-Tech Market Value. (i) The Parties
agree that the number of Nu-Tech Shares then in Escrow shall be subject to
increase on the last day of the Escrow Period in the event that the average
closing bid price of a share of Nu-Tech Common Stock as quoted on the Nasdaq
SmallCap Market for the five (5) trading day period preceding the last day of
the Escrow Period is less than the Nu-Tech Share Closing Value (adjusted for any
forward or reverse stock split effected by Nu-Tech at any time during the Escrow
Period). Nu-Tech shall deliver to the Escrow Payee within five (5) days of the
termination of the Escrow Period all of the additional Nu-Tech Shares required
to equal the Nu-Tech Share Closing Value of the Nu-Tech Shares placed in Escrow
at Closing. No fractional shares shall be issued to Nu-Tech or the Escrow Payee
and all shares shall be rounded down to the nearest full share.

                  (ii) In the event that (a) the Escrow Payee sells all of the
Nu-Tech Shares within 20 days of the date of receipt of the Nu-Tech Shares from
the Escrow and the total aggregate price received by the Escrow Payee with
respect to

                                       15
   16
such sale (not including any brokerage fees, taxes or sales commissions) is less
than $500,000, or (b) the Escrow Payee is unable, despite its good faith
efforts, to sell the Nu-Tech Shares in the open market during such 20 day
period, including by reason of the Nu-Tech shares not being registered, then
Nu-Tech shall pay to the Escrow Payee the difference between $500,000 and the
total aggregate price received by the Escrow Payee (not including any brokerage
fees, taxes or sales commissions). Such payment shall be made by certified check
and with seven (7) business days of receipt by Nu-Tech of appropriate
documentation from the Escrow Payee evidencing the sale or attempt to sell the
Nu-Tech Shares and the total aggregate sales price. Nu-Tech shall bear no
liability with respect to the Escrow Payee in the event that it does not sell or
attempt to sell all of the Nu-Tech Shares within such 20 day period.

         (g) Assumption of Liabilities. Neither NTBM Billing nor Nu-Tech shall
assume any liabilities nor have any responsibility for any other obligation of
Prompt Medical, except as set forth on the Acquired Asset Schedule, as expressly
agreed by NTBM Billing prior to Closing.

         (h) The Closing. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Nu-Tech, 500 Fifth
Avenue, New York, New York 10036, commencing at 10:00 a.m. local time on October
21, 1996 or such other date as Nu-Tech and Sellers may mutually determine (the
"Closing Date").

                                       39
   40
from the PM Shareholders or Prompt Medical. Nu-Tech and NTBM Billing hereby
agree that the information received by them from the PM Shareholders and/or
Prompt Medical shall be used solely for the purpose of evaluating the

         (g) Exclusivity. None of the PM Shareholders will (and the PM

acquisition structured as a merger, consolidation, or share exchange. The PM
Shareholders will notify Nu-Tech immediately if any Person makes any proposal,
offer, inquiry, or contact with respect to any of the foregoing.

  6. Post-Closing Covenants. The Parties agree as follows with respect to the 
period following the Closing.

         (a) General. In case at any time after the Closing any further action
is necessary or desirable to carry out the purposes of this Agreement, each of
the Parties will take such further action (including the execution and delivery
of such further instruments and documents) as any other Party reasonably may
request. The PM Shareholders and Prompt Medical acknowledge and agree that from
and after the Closing NTBM Billing will be entitled to possession of all
documents, books, records (including Tax records), agreements, and financial
data of any sort relating to the Acquired Assets and Acquired Liabilities;
provided, however, NTBM Billing shall maintain all such documents, books,
records, agreements and financial data for a period of five (5) years from the
date hereof or until the expiration of the applicable statute of limitations,
whichever is later.

         (b) Litigation Support. In the event and for so long as any Party
actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection with
(i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction on or prior
to the Closing Date involving Prompt Medical or PM Shareholders with respect to
the business of Prompt Medical, each of the other Parties will cooperate with
him or it and his or its counsel in the contest or defense, make available their
personnel, and provide such testimony and access to their books and records as
shall be necessary in connection with the contest or defense, all at the sole
cost and expense of the contesting or defending Party (unless the contesting or
defending Party is entitled to indemnification therefor under Section 8 below).

         (c) Transition. None of the PM Shareholders, Prompt Medical, NTBM
Billing or Nu-Tech will take any action that is designed or intended to have the
effect of discouraging any lessor, licensor, customer, supplier, or other
business associate of Prompt Medical from maintaining the same business
relationships with NTBM Billing after the Closing as it maintained with Prompt
Medical prior to the Closing. Each of the PM Shareholders and Prompt Medical
will refer all customer inquiries relating to the business of Prompt Medical to
NTBM Billing from and after the Closing.

         (d) Confidentiality. Each of the PM Shareholders and Prompt Medical
will treat and hold as such all of the Confidential Information, refrain from
using any of the

                                       41
   42
Confidential Information except in connection with this Agreement, and deliver
promptly to Nu-Tech or destroy, at the request and option of Nu-Tech, all
tangible embodiments (and all copies) of the Confidential Information which are
in his or its possession. In the event that any of the PM Shareholders or Prompt
Medical are requested or required (by oral question or request for information
or documents in any legal proceeding, interrogatory, subpoena, civil
investigative demand, or similar process) to disclose any Confidential
Information, the PM Shareholder or Prompt Medical will notify Nu-Tech promptly
of the request or requirement so that Nu-Tech may seek an appropriate protective
order (at its expense) or waive compliance with the provisions of this Section
6(d). If, in the absence of a protective order or the receipt of a waiver
hereunder, any of the PM Shareholders or Prompt Medical is, on the advice of
counsel, legally compelled to disclose any Confidential Information or else
stand liable for contempt or other legal sanctions, that PM Shareholder or
Prompt Medical may disclose the Confidential Information as legally compelled;
provided, however, that the disclosing PM Shareholder or Prompt Medical shall
use his, her or its best efforts to obtain, at the reasonable request of Nu-Tech
and at Nu-Tech's expense, an order or other assurance that confidential
treatment will be accorded to such portion of the Confidential Information
required to be disclosed as Nu-Tech shall designate. The foregoing provisions
shall not apply to any Confidential Information which is generally available to
the public immediately prior to the time of disclosure.

         (e) Covenant Not to Compete. During the Escrow Period and for a period
of two (2) years thereafter, none of the PM Shareholders nor Prompt Medical (or
its successors) will engage directly or indirectly in any business that Prompt
Medical conducts as of the Closing Date within 200 miles of Miami, Florida;
provided, however, that no owner of less than 1% of the outstanding stock of any
publicly traded corporation shall be deemed to engage solely by reason thereof
in any of its businesses. The provisions of this Section (e) shall not apply to
the business of Dr. Aaron J. Prussin and/or his professional association. If the
final judgment of a court of competent jurisdiction declares that any term or
provision of this Section 6(e) is invalid or unenforceable, the Parties agree
that the court making the determination of invalidity or unenforceability shall
have the power to reduce the scope, duration, or area of the term or provision,
to delete specific words or phrases, or to replace any invalid or unenforceable
term or provision with a term or provision that is valid and enforceable and
that comes closest to expressing the intention of the invalid or unenforceable
term or provision, and this Agreement shall be

                                       42
   43
enforceable as so modified after the expiration of the time within which the
judgment may be appealed. The PM Shareholders acknowledge that monetary damages
alone will not be an adequate remedy for any breach of this Section 6(e), and
accordingly expressly agree that Nu-Tech shall be entitled to injunctive relief
in any court of competent jurisdiction.

  8. Remedies for Breaches of This Agreement.

         (a) Survival of Representations and Warranties.

All of the representations and warranties of the Parties contained in this
Agreement (as may be modified by the Disclosure Schedule) shall survive the
Closing hereunder (even if the damaged Party knew or had reason to know of any
misrepresentation or breach of warranty at the time of Closing) and continue in
full force and effect for a period of three (3) years thereafter (subject to any
applicable statutes of limitations).

         (b) Indemnification Provisions for Benefit of Nu-Tech.

warranties, and covenants contained herein (other than the covenants in Section
2(a) above and the representations and warranties in Section 3(a) above), and,
if there is an applicable survival period pursuant to Section 8(a) above,
provided that Nu-Tech or NTBM Billing makes a written claim for indemnification
against any of the PM Shareholders or Prompt Medical pursuant to Section 8(d)
below within such survival period, then each of the PM Shareholders or Prompt
Medical, if still in existence, agrees to indemnify Nu-Tech and NTBM Billing
from and against the entirety of any Adverse Consequences they may suffer
(provided, however, in no event shall either be entitled to receive more than
any Adverse Consequences that they may suffer) through and after the date of the
claim for indemnification (including any Adverse Consequences Nu-Tech or NTBM
Billing may suffer after the end of any applicable survival period) resulting
from, arising out of, relating to, in the nature of, or caused by the breach (or
the alleged breach); provided, however, that neither the PM Shareholders nor
Prompt Medical shall have any obligation to indemnify Nu-Tech or NTBM Billing
from and against any Adverse Consequences resulting

                                       46
   47
from, arising out of, relating to, in the nature of, or caused by the breach (or
alleged breach) of any representation or warranty of the PM Shareholders or
Prompt Medical contained in Section 3(a), Sections 4(a)-(j) and Section
4(1)-(aa) above until Nu-Tech or NTBM Billing have suffered Adverse Consequences
by reason of all such breaches (or alleged breaches) in excess of a $10,000
aggregate threshold (at which point the PM Shareholders and Prompt Medical, if
still in existence, will be obligated to indemnify Nu-Tech and NTBM Billing from
and against all such Adverse Consequences relating back to the first dollar).

                  (ii) In the event any of the PM Shareholders or Prompt Medical
breaches (or in the event any third party alleges facts that, if true, would
mean any of the PM Shareholders or Prompt Medical has breached) any of his or
its covenants in Section 2(a) above or any of his or its representations and
warranties in Section 3(a) above, and, if there is an applicable survival period
pursuant to Section 8(a) above, provided that Nu-Tech or NTBM Billing makes a
written claim for indemnification against the PM Shareholder or Prompt Medical
pursuant to Section 8(d)below within such survival period, then the PM
Shareholder and Prompt Medical, if still in existence, agree to indemnify
Nu-Tech or NTBM Billing from and against the entirety of any Adverse
Consequences Nu-Tech or NTBM Billing may suffer (provided, however, in no event
shall Nu-Tech or NTBM Billing be entitled to receive more than any Adverse
Consequences that it may suffer) through and after the date of the claim for
indemnification (including any Adverse Consequences Nu-Tech or NTBM Billing may
suffer after the end of any applicable survival period) resulting from, arising
out of, relating to, in the nature of, or caused by the breach (or the alleged
breach).

                  (iii) Each of the PM Shareholders and Prompt Medical agree to
indemnify Nu-Tech from and against the entirety of any Adverse Consequences
Nu-Tech may suffer (provided, however, in no event shall Nu-Tech or NTBM Billing

Liability of Prompt Medical for the unpaid Taxes of any Person (other than
Prompt Medical) under Treas. Reg. Section 1.1502-6 (or any similar provision of
state, local, or foreign law), as a transferee or successor, by contract, or
otherwise.

         (c) Indemnification Provisions for Benefit of the PM Shareholders and
Prompt Medical. In the event Nu-Tech and/or NTBM Billing breaches (or in the
event any third party alleges facts that, if true, would either mean Nu-Tech or

                                       47
   48
NTBM Billing has breached) any of its representations, warranties, and covenants
contained herein, and, if there is an applicable survival period pursuant to
Section 8(a) above, provided that any of the PM Shareholders or Prompt Medical
makes a written claim for indemnification against Nu-Tech or NTBM Billing
pursuant to Section 8(d) below within such survival period, then NTBM Billing
and Nu-Tech agree to indemnify each of the PM Shareholders and Prompt Medical
from and against the entirety of any Adverse Consequences the PM Shareholder or
Prompt Medical may suffer through and after the date of the claim for
indemnification (including any Adverse Consequences the PM Shareholder or Prompt
Medical may suffer after the end of any applicable survival period) resulting
from, arising out of, relating to, in the nature of, or caused by the breach (or
the alleged breach).

         (d) Matters Involving Third Parties.

                  (i) If any third party shall notify any Party (the
"Indemnified Party") with respect to any matter (a "Third Party Claim") which
may give rise to a claim for indemnification against any other Party (the
"Indemnifying Party") under this Section 8, then the Indemnified Party shall
promptly notify each Indemnifying Party thereof in writing; provided, however,
that no delay on the part of the Indemnified Party in notifying any Indemnifying
Party shall relieve the Indemnifying Party from any obligation hereunder unless
(and then solely to the extent) the Indemnifying Party thereby is prejudiced.

                  (ii) Any Indemnifying Party will have the right to defend the
Indemnified Party against the Third Party Claim with counsel of its choice
reasonably satisfactory to the Indemnified Party so long as (A) the Indemnifying
Party notifies the Indemnified Party in writing within 15 days after the
Indemnified Party has given notice of the Third Party Claim that the
Indemnifying Party will indemnify the Indemnified Party from and against the
entirety of any Adverse Consequences the Indemnified Party may suffer resulting
from, arising out of, relating to, in the nature of, or caused by the Third
Party Claim, (B) the Indemnifying Party provides the Indemnified Party with
evidence reasonably acceptable to the Indemnified Party that the Indemnifying
Party will have the financial resources to defend against the Third Party Claim
and fulfill its indemnification obligations hereunder, (C) the Third Party Claim
involves only money damages and does not seek an injunction or other equitable
relief; provided, however, the Indemnifying Party shall have the right to
participate in such proceedings, (D) settlement of, or an adverse judgment with
respect to, the Third Party Claim is not, in the good

                                       48
   49
faith judgment of the Indemnified Party, likely to establish a precedential
custom or practice materially adverse to the continuing business interests of
the Indemnified Party; provided, however, the Indemnifying Party shall have the
right to participate in such proceedings, and (E) the Indemnifying Party
conducts the defense of the Third Party Claim actively and diligently.

                  (iii) So long as the Indemnifying Party is conducting the
defense of the Third Party Claim in accordance with Section 8(d)(ii) above, (A)
the Indemnified Party may retain separate co-counsel at its sole cost and
expense and participate in the defense of the Third Party Claim, (B) the
Indemnified Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without the prior written
consent of the Indemnifying Party (not to be withheld unreasonably), and (C) the
Indemnifying Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without the prior written
consent of the Indemnified Party (not to be withheld unreasonably).

                  (iv) In the event any of the conditions in Section 8(d)(ii)
above is or becomes unsatisfied, however, (A) the Indemnified Party may defend
against, and consent to the entry of any judgment or enter into any settlement
with respect to, the Third Party Claim in any manner it reasonably may deem
appropriate (and the Indemnified Party need not consult with, or obtain any
consent from, any Indemnifying Party in connection therewith but shall provide
prior notice thereof), (B) the Indemnifying Parties will reimburse the
Indemnified Party promptly and periodically for the costs of defending against
the Third Party Claim (including reasonable attorneys' fees and expenses), and
(C) the Indemnifying Parties will remain responsible for any Adverse
Consequences the Indemnified Party may suffer resulting from, arising out of,
relating to, in the nature of, or caused by the Third Party Claim to the fullest
extent provided in this Section 8.

         (e) Determination of Adverse Consequences. The Parties shall take into
account the time cost of money (using the prime rate as announced by Citibank,
N.A. on the date that any monies required to be paid to a Party hereunder are
due in determining Adverse Consequences for purposes of this Section 8. All
indemnification payments under this Section 8 shall be deemed adjustments to the
Purchase Price.

         (f) Recoupment From Escrow. In the event that the PM Shareholders or
Prompt Medical fail to provide funds to cover any Adverse Consequences suffered
by Nu-Tech or NTBM

                                       49
   50
Billing, Nu-Tech or NTBM Billing shall have the option of recouping all or any
part of any Adverse Consequences it may suffer by notifying the PM Shareholders
and Prompt Medical and the Escrow Agent by delivery of an Adjustment Notice that
Nu-Tech and/or NTBM Billing is entitled to indemnification pursuant to this
Section 8; and such amount of indemnification, provided Nu-Tech and/or NTBM
Billing is entitled to such indemnification pursuant to the terms hereof, shall
be removed from the cash and/or Nu-Tech Shares then in Escrow at the option of
Nu-Tech and/or NTBM Billing. If the third party claimant is willing to accept
Nu-Tech Shares in satisfaction of its claim, and Nu-Tech and/or NTBM Billing may
transfer legally such shares, then the Nu-Tech Shares may be removed from Escrow
to satisfy such Adverse Consequences. All claims under this Section 8(f) shall
be made in compliance with Section 2(d)(ii) hereof regarding notice.

         (g) Other Indemnification Provisions. The foregoing indemnification
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy any Party may have for breach of any
representation, warranty, or covenant; provided, however, in no event shall any
Party be entitled to receive more than the Adverse Consequences that it may
suffer. Each of the PM Shareholders hereby agrees that he or she will not make
any claim for indemnification against Prompt Medical by reason of the fact that
he or it was a director, officer, employee, or agent of Prompt Medical prior to
the Closing (whether such claim is for judgments, damages, penalties, fines,
costs, amounts paid in settlement, losses, expenses, or otherwise and whether
such claim is pursuant to any statute, charter document, bylaw, agreement, or
otherwise) with respect to any action, suit, proceeding, complaint, claim, or
demand brought by Nu-Tech against such PM Shareholder (whether such action,
suit, proceeding, complaint, claim, or demand is pursuant to this Agreement,
applicable law, or otherwise) if such indemnification claim by such PM
Shareholder would result in any Adverse Consequences to Nu-Tech or NTBM Billing.

  9. Registration Rights.

         The Escrow Payee shall be entitled to the registration rights with
respect to the Nu-Tech Shares in accordance with the provisions of this Section
9 as follows:

         (a) Registrable Securities. As used herein the term "Registrable
Security" means the Nu-Tech Shares issued to the Escrow Payee in accordance with
Section 2 hereof; provided, however, that with respect to any particular
Registrable Security, such security shall cease to be a

                                       50
   51
Registrable Security when, as of the date of determination, (i) it has been
effectively registered under the Securities Act of 1933, as amended (the
"Securities Act") and disposed of pursuant thereto, (ii) registration under the
Securities Act is no longer required for the immediate public distribution of
such security, or (iii) it has ceased to be outstanding. The term "Registrable
Securities" means any and/or all of the securities falling within the foregoing
definition of a "Registrable Security." In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Common Stock, such adjustment shall be made in the
definition of "Registrable Security" as is appropriate in order to prevent any
dilution or enlargement of the rights granted pursuant to this Section 9.

         (b) Piggyback Registration. If, at any time commencing after the
Closing Date, Nu-Tech proposes to prepare and file with the Securities and
Exchange Commission (the "Commission") a registration statement, or
post-effective amendment to a previously filed registration statement, covering
equity securities of Nu-Tech, or any such securities of Nu-Tech held by its
shareholders (in any such case, other than in connection with a merger,
acquisition or pursuant to Form S-8 or successor form), (for purposes of this
Section 9, collectively, a "Registration Statement"), it will give written
notice of its intention to do so by registered mail ("Notice"), at least thirty
(30) days prior to the filing of each such Registration Statement, to all
holders of the Registrable Securities. Upon the written request of such a holder
(a "Requesting Holder"), made within ten (10) days after receipt of the Notice,
that Nu-Tech include any of the Requesting Holder's Registrable Securities in
the proposed Registration Statement, Nu-Tech shall, as to each such Requesting
Holder, use its best efforts to effect the registration under the Securities Act
of the Registrable Securities which it has been so requested to register
("Piggyback Registration"), at Nu-Tech's sole cost and expense and at no cost or
expense to the Requesting Holders except as provided in Section 9(c) hereof.

         Notwithstanding the provisions of this Section 9(b), (i) Nu-Tech shall
have the right at any time after it shall have given written notice pursuant to
this Section 2 (irrespective of whether any written request for inclusion of
such securities shall have already been made) to elect not to file any such
proposed Registration Statement, or to withdraw the same after the filing but
prior to the effective date thereof and (ii) Nu-Tech shall not be required to
give notice or include such Shares in any such registration if the proposed
registration is (A) a

                                       51
   52
registration of a stock option or compensation plan or of securities issued or
issuable pursuant to any such plan or (B) a registration of securities proposed
to be issued in exchange for securities or assets of, or in connection with a
merger or consolidation with another corporation;

         (c) Covenants of Nu-Tech With Respect to Registration. Nu-Tech
covenants and agrees as follows:

                  (i) Nu-Tech shall use its best efforts to cause the
Registration Statement to become effective as promptly as possible and, if any
stop order shall be issued by the Commission in connection therewith, to use its
reasonable efforts to obtain the removal of such order. Following the effective
date of a Registration Statement, Nu-Tech shall, upon the request of the Holder,
forthwith supply such reasonable number of copies of the Registration Statement,
preliminary prospectus and prospectus meeting the requirements of the Securities
Act, and other documents necessary or incidental to the public offering of the
Registrable Securities, as shall be reasonably requested by the Holder to permit
the Holder to make a public distribution of the Holder's Registrable Securities.
The obligations of Nu-Tech hereunder with respect to the Holder's Registrable
Securities are subject to the Holder's furnishing to Nu-Tech such appropriate
information concerning the Holder, the Holder's Registrable Securities and the
terms of the Holder's offering of such Registrable Securities as Nu-Tech may
reasonably request in writing.

                  (ii) Nu-Tech shall pay all costs, fees and expenses in
connection with all Registration Statements filed pursuant to Section (a) hereof
including, without limitation, Nu-Tech's legal and accounting fees, printing
expenses, and blue sky fees and expenses; provided, however, that the Holder
shall be solely responsible for the fees of any counsel retained by the Holder
in connection with such registration and any transfer taxes or underwriting
discounts, commissions or fees (in the event Holder wishes to engage an
underwriter, at Holder's option) applicable to the Registrable Securities sold
by the Holder pursuant thereto.

                  (iii) Nu-Tech will take all necessary action which may be
required in qualifying or registering the Registrable Securities included in a
Registration Statement for offering and sale under the securities or blue sky
laws of such states as are reasonably requested by the holders of such
securities, provided that Nu-Tech shall not be obligated to execute or file any
general consent to service of process or to qualify as a foreign corporation to
do business under the laws of any such jurisdiction.

                                       52
   53
  10. Termination.

         (a) Termination of Agreement. Certain of the Parties may terminate this
Agreement as provided below:

                  (i) Nu-Tech and NTBM Billing may terminate this Agreement by
         giving written notice to the PM Shareholders and Prompt Medical on or
         before the the tenth business day after receipt of the Disclosure
         Schedule, Financial Statements, Acquired Asset Schedule and Primary
         Customer Revenue Statement and all other due diligence material
         requested by Nu-Tech and NTBM Billing or at any time on or before the
         Closing if there are material adverse changes to the business of Prompt
         Medical.

                  (ii) The PM Shareholders and Prompt Medical may terminate this
         Agreement by giving written notice to Nu-Tech and NTBM Billing on or
         before the 20th day following the date of this Agreement if the PM
         Shareholders and Prompt Medical are not satisfied with the results of
         their continuing business, legal and accounting due diligence regarding
         Nu-Tech or NTBM Billing or at any time on or before the Closing if
         there are material adverse changes to the business of NuTech or NTBM
         Billing;

                  (iv) Nu-Tech or NTBM Billing may terminate this Agreement by
         giving written notice to the PM Shareholders and/or Prompt Medical at
         any time prior to the Closing (A) in the event any of the PM
         Shareholders or Prompt Medical has breached any material
         representation, warranty, or covenant contained in this Agreement in
         any material respect, Nu-Tech or NTBM Billing has notified the PM
         Shareholders and Prompt Medical of the breach, and the breach has
         continued without cure for a period of 10 days after the notice of
         breach or (B) if the Closing shall not have occurred on or before
         October 21, 1996, by reason of the failure of any condition precedent
         under Section 7(a) hereof (unless the failure results primarily from
         Nu-Tech or NTBM Billing itself breaching any representation, warranty,
         or covenant contained in this Agreement); and

                  (v) the PM Shareholders or Prompt Medical may terminate this
         Agreement by giving written notice to Nu-Tech and NTBM Billing at any
         time prior to the Closing (A) in the event Nu-Tech or NTBM Billing has
         breached any material representation, warranty, or covenant contained
         in this Agreement in any material respect, any of the PM Shareholders
         or Prompt Medical has notified Nu-Tech of the breach, and the breach
         has

                                       53
   54
         continued without cure for a period of 10 days after the notice of
         breach or (B) if the Closing shall not have occurred on or before
         October 21, 1996, by reason of the failure of any condition precedent
         under Section 7(b) hereof (unless the failure results primarily from
         any of the PM Shareholders and/or Prompt Medical themselves breaching
         any representation, warranty, or covenant contained in this Agreement).

         (b) Effect of Termination. If any Party terminates this Agreement
pursuant to Section 10(a) above, all rights and obligations of the Parties
hereunder shall terminate without any Liability of any Party to any other Party
(except for any Liability of any Party then in breach). The foregoing
notwithstanding, Nu-Tech shall remain obligated to pay up to $10,000 to the
independent accountants of Prompt Medical pursuant to Section 11(1) hereof for
the preparation of the Financial Statements.

  11. Miscellaneous.

         (a) Nature of Certain Obligations. The representations, warranties, and
covenants in this Agreement are joint and several obligations. This means that
each Party will be responsible to the extent provided in Section 8 above for the
entirety of any Adverse Consequences any Party may suffer as a result of any
breach thereof; provided, however no Party shall be entitled to receive more
than any Adverse Consequences it may suffer.

         (b) Press Releases and Public Announcements. No Party shall issue any
press release or make any public announcement relating to the subject matter of
this Agreement prior to the Closing without the prior written approval of
Nu-Tech and the PM Shareholders and Prompt Medical; provided, however, that any
Party may make any public disclosure it believes in good faith is required by
applicable law or any listing or trading agreement concerning its
publicly-traded securities (in which case the disclosing Party will use its
reasonable best efforts to advise the other Parties prior to making the
disclosure).

         (c) No Third-Party Beneficiaries. This Agreement shall not confer any
rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns.

         (d) Entire Agreement. This Agreement (including the documents referred
to herein) constitutes the entire agreement among the Parties and supersedes any
prior understandings, agreements, or representations by or among


                                       54
   55
the Parties, written or oral, to the extent they related in any way to the
subject matter hereof.

         (e) Succession and Assignment. This Agreement shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of his
or its rights, interests, or obligations hereunder without the prior written
approval of Nu-Tech and the PM Shareholders and Prompt Medical; provided,
however, that Nu-Tech may (i) assign any or all of its rights and interests
hereunder to one or more of its Affiliates and (ii) designate one or more of its
Affiliates to perform its obligations hereunder (in any or all of which cases
Nu-Tech nonetheless shall remain responsible for the performance of all of its
obligations hereunder). Nothing contained in this Agreement shall be deemed or
construed to prevent the dissolution of Prompt Medical after the Closing;
therefore, Nu-Tech and NTBM agree that the PM Shareholders and Prompt Medical
shall have the right to assign among themselves any and all rights and
obligations hereunder in the event of such dissolution.

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

         (g) Headings. The section headings contained in this Agreement are
inserted for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

         (h) Notices. All notices, requests, demands, claims, and other
communications hereunder will be in writing. Any notice, request, demand, claim,

Any Party may send any notice, request, demand, claim, or other communication
hereunder to the intended recipient at the address set forth above using any
other means (including personal delivery, expedited courier, messenger service,

Party may change the address to which notices, requests, demands, claims, and
other communications hereunder are to be delivered by giving the other Parties

         (i) Governing Law. This Agreement shall be governed by and construed in
accordance with the domestic laws of the State of New York without giving effect
to any choice or conflict of law provision or rule (whether of the State of New
York or any other jurisdiction) that would cause the application of the laws of
any jurisdiction other than the State of New York.

         (j) Amendments and Waivers. No amendment of any provision of this
Agreement shall be valid unless the same shall be in writing and signed by
Nu-Tech, NTBM Billing, Prompt Medical and the PM Shareholders. No waiver by any
Party of any default, misrepresentation, or breach of warranty or covenant
hereunder, whether intentional or not, shall be deemed to extend to any prior or
subsequent default, misrepresentation, or breach of warranty or covenant
hereunder or affect in any way any rights arising by virtue of any prior or
subsequent such occurrence.

         (k) Severability. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.

         (l) Expenses. Each of the PM Shareholders, Prompt Medical, NTBM Billing
and Nu-Tech will bear his, her or its own costs and expenses (including legal
fees and expenses) incurred in connection with this Agreement and the
transactions contemplated hereby. Notwithstanding the

                                       56
   57
foregoing, Nu-Tech hereby agrees that it shall pay, upon receipt of invoices, up
to $10,000 to the independent accountants of Prompt-Medical with respect to the
preparation of the Financial Statements which shall be in form acceptable to
Nu-Tech's independent accountants. The PM Shareholders and Prompt Medical agree
that neither NTBM Billing nor Nu-Tech shall be responsible for any of the PM
Shareholders' or Prompt Medical's costs and expenses (including any of their
legal fees and expenses) in connection with this Agreement or any of the
transactions contemplated hereby, except as set forth above.

         (m) Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise favoring or disfavoring any Party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation. The Parties intend
that each representation, warranty, and covenant contained herein shall have
independent significance. If any Party has breached any representation,
warranty, or covenant contained herein in any respect, the fact that there
exists another representation, warranty, or covenant relating to the same
subject matter (regardless of the relative levels of specificity) which the
Party has not breached shall not detract from or mitigate the fact that the
Party is in breach of the first representation, warranty, or covenant.

         (n) Incorporation of Exhibits and Schedules. The Exhibits and Schedules
identified in this Agreement are incorporated herein by reference and made a
part hereof.

         (o) Specific Performance. Each of the Parties acknowledges and agrees
that the other Parties would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with their specific
terms or otherwise are breached. Accordingly, each of the Parties agrees that
the other Parties shall be entitled to an injunction or injunctions to prevent
breaches of the provisions of this Agreement and to enforce specifically this
Agreement and the terms and provisions hereof in any action instituted in any
court of the United States or any state thereof having jurisdiction over the
Parties and the matter (subject to the provisions set forth in Section 11(p)
below), in addition to any other remedy to which they may be entitled, at law or
in equity.

                                       57
   58
         (p) Submission to Arbitration. Any controversy, claim, or dispute
arising out of or relating to this Agreement, or any breach thereof, including
without limitation any dispute concerning the scope of this arbitration clause,
shall be settled by arbitration in New York, New York before one (1) arbitrator
of the American Arbitration Association ("AAA"), chosen by the AAA in accordance
with the Commercial Arbitration Rules of the AAA as supplemented herein, and
judgment upon the award rendered by the arbitrators may be entered in any court
having jurisdiction thereof. Each party shall have the right to object once to
the arbitrator chosen by the AAA and to require that another arbitrator be
appointed. Pending final award, arbitrator compensation and expenses shall be
advanced equally by both parties. The final award shall include costs and
expenses to be paid to the prevailing party; provided, however, in the event
such Party is found to have been at fault then the costs and expenses shall be
divided pro rata in accordance with the award. The final award may grant such
other, further, and different relief as authorized by the AAA Commercial
Arbitration Rules, but may not include punitive damages.

         (q) Separate Counsel. The PM Shareholders and Prompt Medical hereby
expressly acknowledge that they have been repeatedly advised that they have not
been represented by Nu-Tech's or NTBM Billing's attorney in this matter and have
been advised and urged to seek separate legal counsel for advice in this matter.
Each of the PM Shareholders and Prompt Medical hereby waive any right to raise
as a defense to any claim or dispute the fact that they have refused to obtain
counsel prior to execution of this Agreement. The PM Shareholders and Prompt
Medical hereby acknowledge that they have informed Nu-Tech and NTBM Billing that
they understand the terms and conditions of the transactions contemplated herein
and that the PM Shareholders are sophisticated business persons with experience
in transactions such as those contemplated herein.

         (r) Installment Reporting by PM Shareholders. Nu-Tech and NTBM Billing
understand that Prompt Medical intends to liquidate in a manner that satisfies
the requirements of Section 453B(h) and 453(h) of the Code to avoid recognition
of gain by Prompt Medical on one or more liquidating distributions to the PM
Shareholders, including one or more distributions of its rights under the Escrow
Agreement, and to permit the PM Shareholders to report gain on the liquidation
of Prompt Medical on the installment method, and




                                       58
   59
Nu-Tech and NTNB Billing will cooperate with Prompt Medical and/or the PM
Shareholders as necessary to enable them to implement that intention.

         IN WITNESS WHEREOF, the Parties hereto have executed this Agreement on
the date first above written.
