and properties reflected in the unaudited statement of consolidated financial 
position of Seller as of April 30, 1998,  (Exhibit G), or thereafter acquired,

affecting the Seller, in law or in equity, which involve the likelihood of any 
judgment or liability not fully covered by insurance in excess of $1,000,000 
in the aggregate, or which may result in any material adverse change in the 
business, operations, properties, or assets or in the condition, financial or 
otherwise, of the Seller, except as follows: The Seller is the Petitioner in 
an action entitled Northeast Medical Billing, Petitioner, and Physician Health 
Care Alliance and CHC Physicians, Respondents;

Physician Health Care Alliance and CHC Physicians, Respondents, instituted on 
April 30, 1998,  and now pending before the American Arbitration Association, 
a counterclaim in which claimant seeks to recover the sum of $1,000,000 
million from Seller under the agreement dated September 5, 1996,  between 
Physician Health Care Alliance and CHC Physicians and Seller, and in which the 
Seller had previously asserted a claim against Physician Health Care Alliance 
and CHC Physicians for $300,000. 

     (i) Accounts receivable. The notes and accounts receivable and the other 
receivables of Seller to be assigned to Buyer under this agreement will be 
collectible at their book amounts. Said notes and accounts receivable 
represent bona fide indebtedness arising out of the ordinary course of 
business. They do not represent obligations of Seller's shareholders or 
directors or any of Seller's subsidiaries. Seller shall furnish Buyer with a 
list of accounts and notes receivable. 

     (j) Material transactions. Since April 30, 1998,  Seller has not entered 
into any material transaction other than in the ordinary course of business.

(Exhibit G), other than changes occurring in the ordinary course of business. 

     (l) Good condition. Upon delivery of possession to Buyer, Seller's 
furniture, fixtures, equipment and machinery will be in reasonably good repair 
and working order, capable of producing sound and merchantable service. This 
warranty, however, shall not be deemed to apply to the condition of any 
furniture, fixtures, machinery or equipment not in use in the ordinary course 
of business on the Closing Date. 

     (m) Investment purpose. Seller is acquiring for investment, and not with 
a view to the sale or distribution thereof, the Common Shares to be delivered 
hereunder to Seller, and any Options  to Purchase Common Shares issuable upon 
their conversion. Seller shall not sell or otherwise dispose of any note 
acquired  hereunder unless a registration statement under the Securities Act 
of 1933, as amended, is in effect with respect thereto and Seller has duly 
complied with the Securities Act and all applicable regulations thereunder, or 
Seller has received an opinion from Purchaser's counsel that the contemplated 
sale or other disposition of such notes will not require registration under 
the Securities Act. 

     (n) Values. The unaudited statement of Seller's financial position as of 
the Closing Date to be delivered to Buyer as provided in paragraph 8, as 
compiled by Robert M. Mucha, CPA, PC, will be true and correct. The items 
which will be included in such unaudited statement under the captions 
"Accounts Receivable" and "Furniture and Fixtures" are the same items included 
on the unaudited statement as of April 30, 1998.  These items will have 
current value or will be items which are properly deferrable to future 
operations in accordance with generally accepted accounting practice. The 
certificate of Robert M. Mucha, CPA, PC with respect to such compiled 
statement shall be with qualification.

     (o) Authorization. Seller's Board of Directors has approved this 
agreement and the transactions contemplated herein and has authorized the

assignment, transfer, and delivery of the assets, properties, business,

to the extent that such representations and warranties are incorrect as of the 
Closing Date because of events or changes occurring or arising after the date 
hereof in the ordinary course of Buyer's business or as otherwise provided in 
or permitted by this agreement; and Buyer has delivered to Seller a 
certificate dated the Closing Date, signed by the Buyer's Chief Executive 
Officer to such effect. 


     13. Restrictive covenant. 

     (a) Noncompetition. Seller shall not, for a period of five (5) years from 
the Closing Date, engage, either directly or indirectly, in the business of 
providing or selling medical billing/physician practice management services 
within five hundred (500) miles of any headquarters, regional office, 
domiciled subsidiary or domiciled affiliation of Buyer, and it shall obtain 
from Frank J. DeJohn and Martha T. DeJohn, principal shareholders of Seller, 
individually, and deliver to Buyer on the Closing Date, a commitment to the 
same effect with respect to their personal activities, except on behalf of 
Buyer, for a period of five (5) years from the Closing Date. 

     (b) Other activities. It is expressly understood that Frank J. DeJohn and 
Martha T. DeJohn may, without limitation, own shares in publicly held 
corporations in the medical billing/physician practice management business, if 
any such share ownership does not amount to control of any such corporation. 
Notwithstanding any of the terms and conditions of this paragraph, or this 
Agreement as read in its entirety, the Stockholder will not be prevented from 
serving as an officer, director, control person or beneficial owner of 
Northeast Medical Business Group, Inc., nor will the Stockholder be precluded 
from owning up to one hundred percent (100%) of the preferred and/or common 
equity of said entity.

     (c) Enforceability. The parties believe that the restrictive covenants 
contained in this paragraph are reasonable. However, if any court of competent 
jurisdiction subsequently holds this restriction to be unenforceable or 
unreasonable, whether as to scope, territory, or period of time specified 
herein, such scope, territory, or period of time shall be deemed to be that 
declared or determined as reasonable by the court.

      (d) Injunctive relief. Seller and its principal shareholder recognize 
that Buyer will suffer irreparable damage if the terms of this restrictive 
covenant are violated, and that it will be difficult, if not impossible, to 
compute Buyer's actual damages resulting from such unauthorized competition. 
The parties, therefore, agree that any party may apply to a court of competent 
jurisdiction to enjoin any threatened or actual breach of the covenants 
contained herein. 

     (e) Ability to earn livelihood. The covenant from Frank J. DeJohn and 
Martha T. DeJohn shall contain a provision whereby they acknowledge that they 
have sufficient experience and ability to permit them to obtain employment in 
areas which are not in violation of the restrictive covenants contained 
herein, and that enforcement of such covenants will not prevent them from 
earning a livelihood. The restrictive covenant granted by Frank J. DeJohn and 
Martha T. DeJohn shall be effective during the term of their employment with 
Buyer and for a period of five years thereafter, notwithstanding any contrary 
provision herein. 


     14. Utilization of name. 

     Buyer shall, after the Closing Date, take any action that is necessary 
(including an amendment to its Certificate of Incorporation and the submission 
thereof to the first meeting of shareholders to be held after the Closing 
Date) to utilize the name "Northeast Medical Billing" 


     15. Employment of seller's personnel. 

     (a) Employees. Seller will use its best efforts to persuade its employees 
on the Closing Date to make themselves available for employment by Buyer, and 
Buyer will endeavor to employ such employees on terms and conditions 
comparable to those upon which they were employed by Seller before the Closing 
Date. 

     (b) Principal. Buyer affirms that it intends to employ Frank J. DeJohn 
and Martha T. DeJohn in a principal executive capacity from and after the 
Closing Date, and Seller hereby affirms that it is its understanding that 
Frank J. DeJohn and Martha T. DeJohn intend to enter into the Buyer's 
employment in such a capacity from and after the Closing Date. 

     (c) Right to terminate. If Frank J. DeJohn should die before the Closing 
Date, Seller may terminate this agreement by giving Buyer written notice, 
within three days thereafter, of Seller's exercise of such termination rights. 
If Seller does not exercise its option to terminate, Buyer may terminate the 
agreement by giving written notice to Seller within three business days after 
Seller's three-day period expires. 


     16. Registration of securities.

     (a)  If at any time while Seller holds any of Buyer's Common Shares, 
Buyer takes action to register any of its securities under the Securities Act 
of 1933, as amended, or any similar federal statute, Buyer shall give Seller 
prompt written notice of its intended action on each such occasion. If 
registration of any such securities held by Seller is then possible under 
applicable laws, regulations, and practices of the Securities and Exchange 
Commission or other appropriate governmental agency, and Seller within 15 days 
after receipt of any such notice requests Buyer to do so, Buyer shall, at its 
expense, take action to register the securities at the same time, and use its 
best efforts to the end that such registration shall become effective and that 
no stop order with respect to the registration is issued. In addition, if at 
any time during a period of five years after the Closing Date Seller continues 
to hold any of such securities, and if so requested by Seller, Buyer shall 
take action at Buyer's expense to register such securities under the 
Securities Act of 1933, as amended, or any other appropriate federal statute, 
and use its best efforts to the end that such registration shall become 
effective and that no stop order with respect to the registration is issued. 
In this regard, however, Seller may not make more than three such requests in 
such five-year period. 

     (b) Seller's cooperation. Seller will furnish Buyer correct and complete 
information, including financial statements, data, and other documents Buyer 
shall reasonably request for inclusion in proxy statements, periodic reports, 
and registration statements which Buyer is required to file with the 
Securities and Exchange Commission, appropriate state authorities, and the 
National Association of Securities Dealers as a result of, or pertaining to, 
any transaction contemplated by this agreement, with respect to which the 
foregoing is required. Buyer covenants that any such materials, concerning 
Buyer, to be filed by it with or submitted by it to the above governmental and 
regulatory authorities shall be submitted to and approved by Seller's counsel 
before any filing or submission. 


     17. Survival of representations and warranties. 

     Seller's representations and warranties made in this agreement shall 
survive for a period of 24 months after the Closing Date, except for the 
representation and warranty contained in subparagraph 1(c)(5), relating to 
Seller's liabilities not assumed by Buyer, which shall continue to survive 
until the liabilities therein referred to are satisfied. If Seller is notified 
of a misrepresentation or breach of warranty within 24 months (except that any 
notice with respect to the representation and warranty contained in 
subparagraph 1(c)(5) may be received in more than 24 months) and the 
misrepresentation or breach of warranty is thereafter established, it is 
understood and agreed that Seller shall be liable to Buyer as follows: 

     (a) Undisclosed liabilities. If the misrepresentation or breach of 
warranty is the result of an undisclosed liability, Seller may, either (1) 
assume the payment of such liability, or (2) reimburse Buyer in an amount (A) 
equal to the cost to Buyer of satisfying any such liability after giving 
effect to the amount thereof which will be deductible by Buyer for federal 
income tax purposes at the then applicable tax rate, and (B) equal to 100 
percent of any other such liability.

     (b) Other matters. If the misrepresentation or breach of warranty is the 
result of a matter other than an undisclosed liability, Seller shall put Buyer 
in the position that it would have been in had such representation or warranty 
been true and correct. 
     
     (c) Assumption of liabilities. If Seller elects to assume any liability 
under subparagraph (a) above, it may deliver to Buyer on any date Seller 
designates a sufficient principal amount, in order to enable Seller to satisfy 
such liability. 

     (d) Accounts receivable. If any note, account receivable, or other 
receivable covered by the representation and warranty contained in paragraph 
3(i) is not collectible at the book amount, as provided in paragraph 3(i), 
less normal discounts and allowances, Buyer shall reassign such receivable to 
Seller equal to the receivable's unpaid balance,  For purposes of this 
paragraph, an account or note shall be deemed uncollectible as to that portion 
which remains unpaid for a period of 120 days after it is due. 

     (e) Exclusive remedy. The remedies provided for herein for any 
misrepresentation or breach of warranty by Seller shall be Buyer's sole and 
exclusive remedies and any person claiming under, by, or through Buyer. 

     (f) Buyer's and Seller's representations and warranties. Buyer's and 
Seller's representations and warranties made in this agreement shall not 
survive the Closing Date, and Buyer and Seller shall not have any subsequent 
liability with regard thereto. 

     (g) Physician Health Care Alliance and CHC Physicians litigation. If 
Seller suffers any liability as a result of the litigation referred to in 
paragraph 3(l) or of any subsequent litigation or claim based upon the 
counterclaim referred to therein with Physician Health Care Alliance and CHC 
Physicians, or the settlement thereof, relating to any period prior to the day 
following the Closing Date, Buyer shall not reimburse the Seller for any 
resulting loss. It is expressly understood that any liability as a result of 
any litigation or claims relating to any period after the Closing Date shall 
be Seller's sole responsibility. 


     18. Consent of third party. 

     (a) Assignments. To the extent that the assignment of any contract, 
license, lease, commitment, sales order, or purchase order to be assigned to 
Buyer requires the consent of the other party, this agreement shall not 
constitute an agreement to assign the same if an attempted assignment would 
constitute a breach thereof. Seller will diligently pursue and use its best 
efforts to obtain the consent of the other parties to all such contracts, 
licenses, leases, commitments, sales orders, or purchase orders of Seller to 
the assignment thereof to Buyer. If such consent is not obtained, Seller will 
cooperate with Buyer in any reasonable arrangement designed to provide for 
Buyer the benefits under any such contracts, licenses, leases, commitments, 
service orders, including enforcement, at the cost and for the benefit of 
Buyer, of all Seller's rights against the other party thereto arising out of a 
breach or cancellation by such other party or otherwise. 

     (b) Accounts receivable. Buyer may collect for its account all 
receivables and other items that are transferred to it, and may endorse 
Seller's name on all checks received on account of such items. Seller shall 
deliver to Buyer all cash or other property Seller receives for such items. 


     19.  Fees and expenses.

     (a) Each party shall pay their own fees and expenses incurred in 
preparing this agreement, carrying it into effect, and consummating the 
transactions contemplated hereby. However, if such transactions are not 
consummated because Buyer's directors have failed to take the action required 
under paragraph 9(a), Buyer shall reimburse Seller for its fees and expenses, 
including, without limitation, Seller's reasonable attorneys' and accountants' 
fees, in an amount not exceeding $5,000. 

     (b) Non-liability. Except as provided above, neither party shall have any 
obligation to the other if the transactions contemplated under this agreement 
are not consummated for any reason other than the party's willful failure or 
refusal to comply with its obligations hereunder. In that event, the 
defaulting party shall remain liable for all damages caused by its willful 
failure or refusal. 


     20. Waiver of compliance with bulk sale requirements. 

     Buyer waives Seller's compliance provisions with the provisions of the 
bulk sales law as enacted in any applicable jurisdiction. Seller, however, 
shall indemnify and hold Buyer  harmless from all liabilities and obligations 
of Seller which are not assumed by Buyer under this agreement, and from any 
and all liabilities resulting from noncompliance with the bulk sales law, 
including, but not limited to, all costs and expenses incurred in connection 
with the defense or settlement of any such liability or obligation. 


     21. Assignment of agreement.

     (a) This agreement shall not be assignable by either party except with 
the other's written consent. 

     (b) Third parties. Nothing in this agreement, expressed or implied, is 
intended to confer upon any person, other than the parties hereto and their 
successors and assigns, any rights or remedies under or by reason of this 
agreement. 


     22. Brokerage. 

     Each party represents and warrants that there are no claims for brokerage 
commissions or finders' fees in connection with the transactions contemplated 
by this agreement, insofar as such claims are alleged to be based on 
arrangements or agreements made by it or on its behalf, and each of the 
parties agrees to indemnify the other against and hold it harmless from all 
liabilities arising from any such claim (including, without limitation, cost 
of counsel fees in connection therewith).
 

     23. Notices. 

     All notices and other communications ("Notices") to be given hereunder by 
either party to the other shall be in writing and delivered personally or sent 
by registered or certified mail, postage prepaid, if to Buyer, addressed to

04240, and if to Seller, addressed to Seller, attention of the President, 17

constitute an implied representation by Seller that any of its officers or

cause it to be executed on behalf of Seller. Buyer shall not take any action 
to rescind or revoke this agreement before January 1, 1999.
