8.1      TERMINATION EVENTS. This Agreement can, by notice given before or at
         the Closing, be terminated:

         (a)      By either Party, if the other has committed a material Breach
                  of this Agreement, and the Breach has not been waived and that
                  Party was not in material Breach of this Agreement prior to
                  the Breach that is forming the basis for the proposed
                  termination; PROVIDED, HOWEVER, that the Party that has
                  committed a material Breach will have ten (10) Business Days
                  after receipt of notice from the other Party of its intention
                  to terminate this Agreement pursuant to this Section 8.1(a) to
                  cure such Breach before the other Party may so terminate this
                  Agreement;

         (b)      By the Buyer, if any condition in Section 6 has not been
                  satisfied on or before June 1, 2001 or if satisfaction of the
                  condition is or becomes impossible (other than through the
                  Buyer's failure to comply with its obligations under this

EQUITY PURCHASE AGREEMENT

                  Agreement) and the Buyer has not waived the condition on or
                  before the Closing Date;

         (c)      By the Seller, if any condition in Section 7 has not been
                  satisfied on or before June 1, 2001, or if satisfaction of a
                  condition is or becomes impossible (other than through the
                  Seller' failure to comply with their obligations under this
                  Agreement) and the Seller have not waived the condition on or
                  before the Closing Date;

         (d)      By mutual consent of the Buyer and the Seller; or

         (e)      By either the Buyer or the Seller if the Closing has not
                  occurred (other than through the failure of any Party seeking
                  to terminate this Agreement to comply fully with its
                  obligations under this Agreement) on or before June 1, 2001,
                  or any later date the Parties agree on.

8.2      EFFECT OF TERMINATION. Each Party's right of termination under Section
         8.1 is in addition to any other rights it has under this Agreement or
         otherwise, and the exercise of a right of termination will not be an
         election of remedies. If this Agreement is terminated pursuant to
         Section 8.1, all further obligations of the Parties under this
         Agreement will terminate, except that the obligations in Sections 11.1
         and 11.3 will survive; PROVIDED, HOWEVER, that if this Agreement is
         terminated by a Party because of the Breach of the Agreement by the
         other Party or because one or more of the conditions to the terminating
         Party's obligations under this Agreement is not satisfied as a result
         of the other Party's failure to comply with its obligations under this
         Agreement, the terminating Party's right to pursue all legal remedies
         will survive such termination unimpaired.

                               9. INDEMNIFICATION

9.1      INDEMNIFICATION. All the representations, warranties, covenants and
         agreements of the Seller and the Buyer contained in this Agreement
         shall not survive the Closing Date. Each of Buyer and Seller shall not
         have any liability under this Agreement of any sort whatsoever, except
         in the case of either fraud or willful misconduct (i.e., an intentional
         breach of a representation, warranty, covenant or agreement, but
         excluding a negligent or reckless breach) by the Buyer or Seller, as
         applicable, of any of its representations, warranties, agreements or
         covenants contained in this Agreement or in any other instrument or
         document required to be delivered pursuant to this Agreement in
         connection herewith; PROVIDED, HOWEVER, that (i) Buyer shall indemnify,
         defend and hold Seller and its respective Representatives,
         stockholders, controlling Persons, and affiliates (collectively, the
         "Seller' Indemnified Persons"), harmless from and against any claims or
         damages arising after the Closing resulting from the operation of the
         Company's business by Buyer after the Closing Date and (ii) Buyer or
         Seller, as applicable, shall indemnify, defend and hold the Seller
         Indemnified Parties or the Buyer Indemnified Parties, as applicable,
         harmless from and against any claims for finder's fees or broker's
         commissions arising out of any arrangements made by or for the
         indemnifying party, if any. In the event of a fraudulent or willful
         breach, Buyer or Seller, as applicable, shall indemnify, defend and
         hold the Seller Indemnified Persons or the Buyer Indemnified Persons,
         as applicable, harmless for any loss, liability, claim, damage, setoff,

EQUITY PURCHASE AGREEMENT

         recoupment, disgorgement expense (including costs of investigation and
         defense and reasonable attorney's fees), whether or not involving a
         third-party claim. "Buyer Indemnified Persons" shall collectively mean
         the Buyer, the Company, and its respective Representatives,
         stockholders, controlling Persons and Affiliates.

9.2      PROCEDURE FOR INDEMNIFICATION - THIRD PARTY CLAIMS.

         9.2.1 NOTICE. Promptly after receipt by an indemnified Party under
         Section 9.1 of notice of the commencement of any Proceeding against it,
         the indemnified Party will, if a claim is to be made against an
         indemnifying Party under that Section, give notice to the indemnifying
         Party of the commencement of the claim. The failure to notify the
         indemnifying Party will not relieve the indemnifying Party of any
         liability that it could have to any indemnified Party, except to the
         extent that the indemnified Party demonstrates that the defense of the
         action is prejudiced by the indemnifying Party's failure to give the
         notice.

         9.2.2 PARTICIPATION. If any Proceeding referred to in Section 9.2.1 is
         brought against an indemnified Party and it gives notice to the
         indemnifying Party of the commencement of the Proceeding, the
         indemnifying Party will be entitled to participate in the Proceeding
         and, to the extent that it wishes (unless the indemnifying Party is
         also a party to the Proceeding and the indemnified Party determines in
         good faith that joint representation would be inappropriate), to assume
         the defense of the Proceeding with counsel reasonably satisfactory to
         the indemnified Party and, after notice from the indemnifying Party to
         the indemnified Party of its election to assume the defense of the
         Proceeding, the indemnifying Party will not, as long as it diligently
         conducts the defense, be liable to the indemnified Party under this
         Section 9 for any fees of other counsel or any other expenses with
         respect to the defense of the Proceeding, in each case subsequently
         incurred by the indemnified Party in connection with the defense of the
         Proceeding, other than reasonable costs of investigation. If the
         indemnifying Party assumes the defense of a Proceeding, (a) no
         compromise or settlement of the claims will be effected by the
         indemnifying Party without the indemnified Party's consent unless (i)
         there is no finding or admission of any violation of Laws or any
         violation of the rights of any Person and no adverse effect on any
         other claims that could be made against the indemnified Party, and (ii)
         the sole relief provided is monetary damages that are paid in full by
         the indemnifying Party; and (b) the indemnified Party will have no
         liability with respect to any compromise or settlement of the claims
         effected without its consent. If notice is given to an indemnifying
         Party of the commencement of any Proceeding and the indemnifying Party
         does not, within ten days after the indemnified Party's notice is
         given, give notice to the indemnified Party of its election to assume
         the defense of the Proceeding, the indemnifying Party will be bound by
         any determination made in the Proceeding or any compromise or
         settlement effected by the indemnified Party.

                             10. GENERAL PROVISIONS

10.1     EXPENSES. Except as otherwise expressly provided in this Agreement,
         each Party will bear its respective expenses incurred in connection
         with the preparation, execution, and performance of this Agreement and
         the Transactions, including all fees and expenses of agents,

EQUITY PURCHASE AGREEMENT

<PAGE>

         representatives, counsel and accountants. If this Agreement is
         terminated, the obligation of each Party to pay its own expenses will
         be subject to any rights of that Party arising from a Breach of this
         Agreement by another Party.

10.2     PUBLIC ANNOUNCEMENTS. Neither Party will make any public announcement
         about, or otherwise disclose publicly, this Agreement, the Transactions
         or the related negotiations without prior consultations and
         coordination with the other Party; PROVIDED, HOWEVER, (a) that either
         Party can make any public announcement that its counsel advises is
         required by Law or (b) either party can make any public announcement
         with the prior written consent of the other party, such consent not to
         be unreasonably withheld.

10.3     CONFIDENTIALITY . Between the date of this Agreement and for two years
         after the Closing Date, each Party will maintain in confidence, and
         will cause its Affiliates, directors, officers, employees, agents, and
         advisors to maintain in confidence, any written, oral, or other
         information obtained from the other Party (or, in the case of the
         Buyer, the Company), or generated by the Party (such as analyses,
         compilations, studies or similar documents) in connection with the due
         diligence, negotiations and regulatory filings relating to this
         Agreement or the Transactions, and to use such information only in
         connection with the evaluation and negotiation of the Transactions. A
         receiving Party can, however, disclose such information to those of its
         Representatives who have a need to know such information in connection
         with ongoing due diligence, negotiations or regulatory filings with
         respect to this Agreement or the Transactions. In addition, the
         foregoing restrictions will not apply to information that (a) was
         generally available to the public prior to disclosure by the disclosing
         Party; (b) became generally available to the public, other than as a
         result of a disclosure by the disclosing Party or its Representatives;
         or (c) became available to the receiving Party on a non-confidential
         basis from a source not known by the receiving Party to be bound by a
         confidentiality agreement. If the Transactions are not consummated, (1)
         each receiving Party will return to the disclosing Party or destroy as
         much of the written information as the other Party reasonably requests;
         and (ii) the foregoing confidentiality provisions will remain in full
         force and effect for two years, despite the termination of this
         Agreement.

10.4     NOTICES. All notices, consents, waivers, and other communications under
         this Agreement must be in writing. They will be deemed to have been
         duly given when (a) delivered by hand (with written confirmation of
         receipt), (b) sent by telecopier (with written confirmation of
         receipt), so long as a copy is mailed by registered mail, return
         receipt requested, or (c) when received by the addressee, if sent by a
         nationally recognized overnight delivery service (receipt requested),
         in each case to the appropriate addresses and telecopier numbers stated
         below (or as a Party otherwise designates by notice to the other

10.5     ARBITRATION.

         10.5.1 RESOLUTION OF DISPUTES. The Parties will submit all
         controversies, disputes or claims for indemnification among them
         arising out of or relating to this agreement or the Transaction to
         binding arbitration as provided below. The arbitration and all related
         preliminary proceedings will be agreed upon by the Parties, or, failing
         agreement on those rules within thirty days of written request for
         agreement, in accordance with the Rules for Commercial Arbitration of
         the American Arbitration Association ("AAA"), as amended from time to
         time and as modified by this agreement. The dispute will be presented
         to a single arbitrator (the "Arbitrator") sitting in San Diego,
         California.

EQUITY PURCHASE AGREEMENT
ENVISION OPEN MRI, LLC DBA OPEN MRI @ HEALVIEW                           Page 11
<PAGE>

         10.5.2 SELECTION OF THE ARBITRATOR. The Parties will Jointly select the
         Arbitrator within fifteen days after demand for arbitration is made by
         a Party. If the Parties are unable to agree on an Arbitrator within
         that period, then any Party may request that the AAA select the
         Arbitrator in accordance with its then existing rules for doing so. The
         Arbitrator must possess substantive legal experience in the principal
         issues in dispute.

         10.5.3 DISCOVERY. Any discovery permitted will be limited to
         information directly relevant to the controversy in arbitration. In the
         event of discovery disputes, the Arbitrator is directed to issue orders
         as are appropriate to limit discovery in accordance with the foregoing
         and as are reasonable in light of the issues in dispute, the amount in
         controversy, and other relevant considerations. To the extent the
         Parties are unable to agree on the scope of discovery, the Arbitrator
         will require the Party seeking discovery on an issue to present the
         legal and factual basis for the dispute and will permit the Party
         opposing discovery to respond. The Arbitrator will permit discovery on
         an issue only if he or she concludes that there is a reasonable and
         good faith basis in law and in fact for bringing the allegations and
         that the discovery appears likely to present substantive evidence
         regarding that dispute. The Arbitrator may allow limited discovery to
         permit investigation of some of the disputes or to determine whether a
         claim has sufficient basis in law or in fact to warrant further
         discovery. The Arbitrator, however, will issue appropriate orders to
         restrict the scope of that discovery. The federal or state rules of
         procedure and evidence will not apply to the arbitration proceedings,
         including without limitation the rules of discovery. The Arbitrator
         will consider claims of privilege, work product and other restrictions
         on discovery as appear to be warranted.

         10.5.4 FEES. The Arbitrator will award the prevailing Party its
         attorney's and experts' fees and disbursements incurred in resolving
         the dispute and will award double costs and expenses or other sanctions
         to the extent the Arbitrator finds any dispute advanced in the
         proceedings to be frivolous or without a good faith basis in fact and
         in Law when the dispute was first presented for arbitration.

         10.5.5 AWARD/CONSENT TO JURISDICTION. Except as may otherwise be agreed
         in writing by the Parties or as ordered by the Arbitrator upon
         substantial justification shown, the hearing for the dispute will be
         held within ninety days of submission of the dispute to arbitration.
         The Arbitrator will render a final award within thirty days following
         conclusion of the hearing and any required post-hearing briefing or
         other proceedings ordered by the Arbitrator. The Arbitrator will state
         the factual and legal basis for the award. The decision of the
         Arbitrator will be final and binding, except as provided in the Federal
         Arbitration Act, 9 U.S.C.ss.1. ET. SEQ., and except for errors of law
         based on the findings of fact. Final judgment may be entered upon the
         award in any court of competent jurisdiction, but entry of judgment
         will not be required to make the award effective. By signing below, the
         Parties irrevocably submit to the exclusive jurisdiction and venue of
         the state and federal courts and arbitration forum located in San
         Diego, California. THE PARTIES EXPRESSLY WAIVE THEIR RIGHTS TO A TRIAL

                                   SECTION 11.
                                    COVENANTS

         11.1. ACCESS TO INFORMATION. From and after the date hereof and until
the Closing, Seller will give to the Purchaser and the Purchaser's authorized
representatives reasonable access during normal business hours to its offices,

and copies of documents and all such additional financial and operating data and
other information pertaining to the affairs of Seller as the Purchaser and its

activities of the Purchaser and its representatives shall be conducted in such a
manner as not to interfere with the operation of the Business.

         11.2. CONDUCT OF BUSINESS. During the period from the date hereof to

assume responsibility for the vacation time and sick leave benefits due from
Seller to the Transferred Employees as of the Closing Date.

         11.5. GUARANTIES. Purchaser shall use all reasonable efforts to cause
itself or one or more of its affiliates to be substituted in all respects for
Seller or USD, as the case may be, effective as of the Closing, in respect of
all obligations of Seller and USD under each of the contracts, guaranties,
letters of credit, letters of comfort, bid bonds, performance bonds and other
similar type bonds obtained or granted by Seller or USD or any of its affiliates
for the benefit of the Business or relating to the Assets, which contracts,
guaranties, letters of credit, letters of comfort, bid bonds and performance
bonds are set forth on SCHEDULE 11.5 (the "GUARANTIES"). If Purchaser is unable
to effect such a substitution with respect to any Guaranty after using its best
efforts to do so, Purchaser shall obtain letters of credit, on terms and from
financial institutions satisfactory to Seller, with respect to the obligations
covered by each of the Guaranties for which Purchaser does not effect such
substitution. As a result of the substitution contemplated by the first sentence
of this Section 11.5 and/or the letter or letters of credit contemplated by the
second sentence hereof, Seller and USD shall from and after the Closing cease to
have any obligation whatsoever arising from or in connection with the Guaranties
except for obligations, if any, for which Seller and USD will be fully

satisfactory to Seller.

         11.7. USE OF NAME. Purchaser shall have the right to continue to use
the name "Laguna Niguel MRI" with respect to its operations of the Business to

any manner with the name "U S Diagnostic Inc." or any service marks or logos of
USD. Purchaser shall also have the right to use existing telephone numbers of
Laguna Niguel MRI.

         11.8. INSURANCE MATTERS. Seller shall be responsible and liable for the
expense of all worker's compensation claims that arise out of any injury or
damage sustained prior to the Closing Date. The Purchaser shall be responsible
and liable for the expense of all bodily injury, property damage and worker's
compensation claims that arise out of any injury or damage sustained on or after
the Closing Date.

         11.9 PUBLICITY. Except as otherwise required by applicable law or the
disclosure rules and regulations of the Securities Exchange Commission,
Purchaser shall not issue any press release or make any other public statement
(including statements to Employees) relating to this Agreement or the
transactions contemplated hereby without obtaining the prior written approval of
Seller to the contents and manner of presentation and publication thereof.

         11.10 REIMBURSEMENT OBLIGATIONS. The parties acknowledge that
overpayments or underpayments to Seller by the Medicaid or Medicare programs or
other third party payors for periods ending prior to the Closing Date may be
discovered after the Closing, whether in connection with an audit of the
Business or otherwise. Seller shall remain liable for all such overpayments
received by Seller. Seller shall be entitled to receive any additional payments

                                       18

         (a) All representations and warranties of the parties contained in this
Agreement or in any schedule hereto shall survive the Closing only until the
first anniversary of the Closing Date; provided, however, the representations
and warranties set forth in Section 5.10 (Environmental Matters) shall not
survive the Closing. No action or proceeding may be brought with respect to any
of the representations or warranties set forth in this Agreement, unless written
notice thereof, setting forth in reasonable detail the claimed misrepresentation
or breach of warranty shall have been delivered to the party alleged to have
breached such representation or warranty prior to the expiration of the survival
terms set forth for such representation or warranty in the preceding sentence.

         (b) The covenants and agreements contained in Sections 11.1, 11.2 and
11.3 shall not survive the Closing. The remaining covenants or agreements
(including but not limited to the indemnities) contained in this Agreement shall
survive the execution and delivery hereof and the completion of the transactions
contemplated herein.

         12.2. INDEMNIFICATION BY SELLER. Seller agrees to indemnify Purchaser
with respect to, and hold Purchaser harmless from, any loss, liability, damage,
cost or expense (including, but not limited to, reasonable legal fees and
expenses, but specifically excluding any Tax Losses, the responsibility for
which, if any, is provided in Section 10 hereof) (collectively, the "LOSSES")
which Purchaser may incur or suffer which results from or arises out of (a) the
inaccuracy of any representation or warranty made by Seller in this Agreement
(unless any inaccuracy is corrected by Seller or USD prior to Closing in a
supplement to any schedule hereto), or (b) the failure of Seller to comply with
any covenants or other commitments made by Seller in this Agreement, or (c) the
operation of the Business prior to the Closing Date; PROVIDED, HOWEVER, (i) the
Purchaser shall not be entitled to indemnification until all such Losses exceed,
in the aggregate $50,000, in which case the Purchaser shall be entitled to
indemnification only to the extent such Losses exceed $50,000, (ii) the
Purchaser shall not be entitled to indemnification with respect to any breach of
any representation or warranty under Section 5 hereof if Seller can prove by a
preponderance of the evidence that any director or officer of the Purchaser or
doctor employed or retained by Purchaser had actual knowledge at any time on or
prior to the Closing Date of the events or conditions constituting or resulting
in such breach of representation or warranty or were the result of operations
conducted by Purchaser prior to the Closing Date, (iii) in no event shall Seller
be required to pay an aggregate amount in excess of $500,000 in respect of
Purchaser's Losses, and (iv) Losses shall be net of any insurance proceeds
payable or tax benefits realizable to the indemnified party with respect to the
Loss.

                                       19
<PAGE>

         12.3. INDEMNIFICATION BY PURCHASER. Purchaser agrees to indemnify
Seller with respect to, and hold Seller harmless from, any Losses (specifically
excluding Tax Losses, the responsibility for which, if any, is provided in
Section 10 hereof) which Seller may incur or suffer which results from or arises
out of (a) the Assumed Obligations, (b) the inaccuracy of any representation or
warranty made by Purchaser in this Agreement, (c) the failure of Purchaser to
comply with any covenants or other commitments made by Purchaser in this
Agreement, or (d) the operation of the Business on and after the Closing Date;
provided however, (i) the Seller shall not be entitled to indemnification until
all such Losses exceed, in the aggregate $50,000, in which case Seller shall be
entitled to indemnification only to the extent such Losses exceed $50,000; (ii)
in no event shall Purchaser be required to pay an aggregate amount in excess of
$500,000; and (iii) Losses shall be net of any insurance payable to the
indemnified party with respect to the Loss.

         12.4. PROCEDURES FOR INDEMNIFICATION. Promptly after receipt by an
indemnified party under Sections 12.2 and 12.3 of notice of the commencement of
any action for which indemnification may be available under Section 12.2 or
12.3, such indemnified party shall, if a claim in respect thereof is to be made
against an indemnifying party under such Section, give notice to the
indemnifying party of the commencement thereof, but the failure so to notify
that indemnifying party shall not relieve it of any liability that it may have
to any indemnified party, except to the extent the indemnifying party
demonstrates that the defense of such action is prejudiced thereby. In case any
such action shall be brought against an indemnified party and it shall give
notice to the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it shall
elect, to assume the defense thereof with counsel reasonably satisfactory to
such indemnified party and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
Section for any fees of other counsel or any other expenses, in each case
incurred by such indemnified party in connection with the defense thereof, other
than reasonable costs of investigation and costs and expenses of legal counsel
if the indemnified party and the indemnifying party are both parties to the
action and the indemnified party has been advised by counsel that there may be
one or more defenses available to it and not available to the indemnifying party
which defenses result in a conflict of interest. If an indemnifying party
assumes the defense of such an action, (a) no compromise or settlement thereof
may be effected by the indemnifying party without the indemnified party's
consent (which shall not be unreasonable withheld) unless (i) there is no
finding or admission or any violation of law or any violation of the rights of
any person and no effect on any other claims that may be made against the
indemnified party and (ii) the sole relief provided is monetary damages that are
paid in full by the indemnifying party and (b) the indemnifying party shall have
no liability with respect to any compromise or settlement thereof effected
without its consent (which shall not be unreasonably withheld).

         12.5. LIMITATION OF RECOURSE. The rights of the parties for
indemnification relating to this Agreement or the transactions contemplated
hereby shall be strictly limited to those contained in Section 12 hereof, and
such indemnification rights shall be the exclusive remedies of the parties
subsequent to the Closing Date with respect to any matter in any way relating to
this Agreement or arising in connection herewith.

         12.6. PUNITIVE DAMAGES. No party to this Agreement shall seek or be
entitled to punitive, exemplary and/or consequential damages with respect to any
claim.

         material respect any obligation or covenant to be performed by it
         pursuant to this Agreement or pursuant to the agreements relating to

         not been cured within ten (10) business days following the receipt of
         notice by the Purchaser of the breach; or

         the agreements relating to the Related Transactions has not been

         under the agreements relating to the Related Transactions), Seller or
         USD has not waived such condition on or before the Closing Date.

                  (b) The Purchaser may terminate this Agreement by delivery of
notice of termination to Seller if any time prior to the Closing Date:

                           (i) USD or Seller fails or refuses to perform in any
         material respect any obligation or covenant to be performed by it

         the agreements relating to the Related Transactions), the Purchaser has
         not waived such condition on or before the Closing Date.

                  (c) The parties may terminate this Agreement at any time prior
to the Closing Date by mutual written consent.

         13.2. EFFECT OF TERMINATION. Each party's right of termination under
Section 13.1 is in addition to any other rights it may have under this Agreement
or otherwise, and the exercise of a right of termination shall not be an
election of remedies. If this Agreement is terminated pursuant to Section 13.1,

                                       21

except that the rights and obligations in Sections 11.9, 14.4, 14.6, 14.7, 14.12
and 14.13 of this Agreement shall survive; provided, however, notwithstanding
anything to the contrary contained in this Agreement, that if this Agreement is
terminated by a party because of the breach of the Agreement by another party or
because one or more of the conditions of the terminating party's obligations
under this Agreement is not satisfied as a result of the other party's failure
to comply with its obligations under this Agreement, the terminating party's
right to pursue all legal remedies shall survive such termination unimpaired.

systems, utilization and profits, and the procedures, forms and techniques for
servicing accounts, any other operating and procedure manuals, product-lines
developed by Seller Entities, together with any other materials prepared or
provided by, or on behalf of Seller Entities (collectively, the "TRADE
SECRETS"). Purchaser understands that the Trade Secrets are confidential and
proprietary materials of Seller Entities. Purchaser agrees to keep the Trade
Secrets confidential and not to use the Trade Secrets or reveal the Trade
Secrets to any other person or entity, unless required by law. Purchaser shall
also obligate each of its employees and agents to a level of care sufficient to
protect the Trade Secrets from unauthorized use or disclosure. Upon the request
of Seller Entities, Purchaser shall return the Trade Secrets to Seller Entities.

         14.13. ATTORNEYS' FEES. In the event that a suit for the collection of

25-mile radius of the primary location of the Business (the "Restricted
Location"), directly or indirectly, owning, managing, operating, controlling or
financing, any mobile or fixed diagnostic imaging business that is competitive

at this location; provided, however, that the foregoing shall not apply to the
ownership of not more than five (5) percent of the outstanding capital stock of
any company listed by a national securities exchange or an over-the-counter
stock listed by the National Association of Securities Dealers; and provided,

a multi-facility company engaged in a business with is competitive with the

of this covenant by virtue of the consummation of any such merger or
acquisition.

         14.15. EMPLOYEE DISCUSSIONS. USD and Seller each expressly authorize
and empower Purchaser, prior to the Closing Date, to commence negotiations and
discussions with any past and/or present employees of either entity working at
the center, and if appropriate, thereafter enter into employment agreements to
become effective on the Closing Date; it being understood that any such
employment agreements shall be subject to any restrictions contained in any
existing written employment agreements between USD or Seller and any such
individuals.

         14.16. COLLECTION OF AR. USD shall continue to collect accounts
receivable ("AR") acquired by Purchaser for a period of one hundred twenty days
after the Closing Date. Subject to the provisions provided below, USD shall
remit received AR to Purchaser on a semi-monthly basis. USD shall receive a
collection fee of 3% of AR collected. USD shall also receive an additional fee
for its collection efforts determined as follows:

                  On amounts collected, up to a maximum of $100,000, calculated
as a combined percentage equal to the percent of $100,000 to the net realizable
value of accounts receivable as of the Date of Closing, plus an additional 10%.
For example, $100,000 would equal 20.8% of an assumed net realizable value of
accounts receivable at closing of $480,000; and an additional 10% would make the
combined percentage of collected accounts receivable to be paid to USD, 30.8%.
USD would thus receive 30.8% of ongoing collections up to the maximum of
$100,000.

If the accounts receivable is more or less than $480,000 (as referenced in the
agreed-upon Letter of Intent dated February 12, 2001), then the $100,000
referred to in the previous paragraph will be increased/reduced proportionally.
