           the options granted hereunder shall be subject to adjustment in
           accordance with the provisions of Section 12 of this Plan. Such
           shares may be treasury shares or  authorized but unissued shares.

           If any outstanding Option for any reason shall expire or terminate by
           reason of the death of the Optionee or the fact that the optionee
           ceases to be a director, the surrender of any such Option, or any
           other cause, the shares of Common Stock allocable to the unexercised
           portion of such Option may again be subject to an Option under this
           Plan.

     2.    Except as expressly amended by this Amendment, the UroCor, Inc. 1997
           Non-Employee Director Stock Option Plan shall continue in full force

TYPE:  EX - 4.1
SEQUENCE:  1
DESCRIPTION:  CONSULTING AGREEMENT AND COMPENSATION PLAN

                   CONSULTING AGREEMENT AND COMPENSATION PLAN

THIS AGREEMENT is entered into as of this 3rd day of January, 2000 by and
between Solomon Alliance Group, Inc. (the "Company") and David T. Shaheen
("Consultant").

                                    RECITALS:

A.   The Company's shares are traded on the NASDAQ OTC Bulletin Board quotation
system and the Company desires to engage Consultant, formerly counsel to the
Company until December 1999, to assist the Company with business strategy and
development activities.

B.   Consultant has advised the Company that he has the necessary expertise and
knowledge to properly assist the Company in the development of the Company and
its business.

NOW, THEREFORE, in consideration of and based upon the Recitals, the mutual
covenants contained herein, and other good and valuable consideration, the
receipt and legal sufficiency of which are hereby acknowledged, the parties
hereto agree as follows:

1.   DESCRIPTION OF SERVICES. Following execution hereof by both parties,
     Consultant will provide the following business development services, none
     of which involve the financing of the Company through an issuance of
     securities or promoting or maintaining a market for the Company's
     securities (collectively, the "Services"):

          (a)  Advise regarding the Company's business objectives, including
               achieving reporting status as a public company;
          (b)  Assistance in the identification of potential acquisition
               candidates and business opportunities;
          (c)  Identification of opportunities for business and
               revenue-generation for the Company;
          (d)  Assistance with the valuation and due diligence requirements of
               strategic acquisitions and opportunities and the structuring of
               the terms of such transactions;
          (e)  Identification of potential board members or other key personnel
               for the Company's consideration; and
          (f)  Other services pertaining to the growth, development and
               compliance responsibilities of the Company as may be requested
               and agreed by the parties.

2.   COMPENSATION FOR SERVICES. As compensation for Services, the Company will
     issue to Consultant, for a per share purchase price to Consultant of $0.10
     per share, up to 500,000 shares of its $0.001 par value common stock. The
     Company acknowledges that payment for the shares has been made in full by
     the rendering of certain valuable services. Compensation to the Consultant
     may be made by stock grant, stock options or warrants as follows:

         (a)  A warrant for 150,000 shares of the Company, exercisable for five
              years at $0.10 per share, will be delivered to the Consultant in
              March 2000 in consideration of Consultant's advisory services on
              an ongoing basis during the first calendar quarter of the year
              2000.

<PAGE>

          (b)  100,000 shares of restricted stock will be issued to the
               Consultant in the event that the Consultant identifies for the
               Company an appropriate corporation for a business combination
               with the Company. Such restricted stock, valued by the Company at
               $0.10 per share, will only be issued following an agreement
               between the parties regarding the foregoing.

          (c)  Stock option for 100,000 shares of the Company, exercisable for
               five years at $0.10 per share, will be delivered to the
               Consultant in June 2000 in consideration of Consultant's advisory
               services on an ongoing basis during the second calendar quarter
               of the year 2000.

          (d)  Additional stock options shall be granted to the Consultant
               pursuant to agreement between the parties in connection with the
               rendering of any additional Services for the benefit of the
               Company.

3.   RESERVATION OF SHARES. The maximum number of authorized but unissued shares
     of the Company's Common Stock that the Company may be required to issue on
     the grant of awards or on the exercise of options or warrants under this
     Plan is hereby reserved for such purpose. The Board of Directors may
     increase the number of shares subject to this Plan as it may deem necessary
     or advisable for additional grants or as a consequence of a stock split or
     other reorganization or recapitalization affecting all Common Shares.

4.   CAPITAL ADJUSTMENTS. The number and consideration of shares of Common Stock
     covered by each award and the total number of shares that may be granted or
     sold under the Plan shall be proportionally adjusted to reflect, subject to
     any required action by stockholders, any stock dividend or split,
     recapitalization, merger, consolidation, spin-off, reorganization,
     combination or exchange of shares or other similar corporate change.

5.   RULE 428 PROSPECTUS INFORMATION. The parties agree that this Agreement
     shall be deemed an "employee benefit plan" as defined in Rule 405 of
     Regulation C under the Securities Act of 1933 and that the "plan" shall be
     self administered by Consultant. Consultant acknowledges the following:

         (a)  The Company will cause to be filed a registration statement on
              Form S-8 to register the common stock issued to Consultant by the
              Company pursuant to this agreement and to register the resale of
              that common stock.

         (b)  The information contained in Form S-8 and any resale prospectus
              may disclose details concerning this agreement, which disclosure
              will not be confidential.

         (c)  This Agreement is compensatory in nature and purpose with respect
              to obligations of the Company owing to Consultant, which from time
              to time will be current obligations, and is not subject to any
              provisions of the Employee Retirement Income Security Act of 1974.

         (d)  Consultant shall self-administer this plan and has the sole
              discretion to dispose of or distribute the securities issued
              under this Agreement, unless prohibited by law.

         (e)  The common stock of the Company issued under this agreement has
              been registered under Section 12(g) of the Securities Exchange
              Act of 1934.

         (f)  As an "employee benefit plan" this agreement is limited to the
              benefit of Consultant. The Company, however, may enter into
              similar agreements from time to time which constitute separate
              employee benefit plans for other consultants, advisors,
              employees, directors or officers of the Company.

<PAGE>

          (g)  Consultant is not required to contribute toward the securities
               issued under this agreement, except for services rendered by
               Consultant under this agreement.

          (h)  Given the nature of this agreement as compensatory in nature and
               purpose and the sole discretion of Consultant in administering
               this plan, the Company will not issue any reports concerning the
               plan to Consultant, other than to provide an annual recap of the
               securities issued and cash paid hereunder as required by the
               Internal Revenue Code and appurtenant rules and regulations.

          (i)  The Company has not imposed any resale restrictions on the
               securities issued under this agreement.

          (j)  This plan is not qualified under Section 401 of the Internal
               Revenue Code of 1986. The value of the securities issued under
               this agreement constitutes ordinary income to Consultant.

          (k)  This agreement cannot be assigned or hypothecated by Consultant.

          (l)  This agreement will terminate or be forfeited as provided herein.

          (m)  This agreement does not provide for the holding of securities,
               funds or other assets and, as such, no lien has or may be created
               on any such securities, funds or assets.

6.   NON-CIRCUMVENTION. In and for valuable consideration, the Company hereby
     agrees that Consultant may take actions to introduce the Company (whether
     conveyed in written, oral or data format, or otherwise by Consultant) to
     certain business opportunities proprietary to Consultant (the
     "Opportunities") for the benefit of the Company. The Company further
     acknowledges and agrees that the identity of the subject Opportunities, and
     all other information concerning the Opportunity (including without
     limitation, all mailing information, phone and fax numbers, email addresses
     and other contact information) introduced hereunder are proprietary to
     Consultant, and shall be treated as confidential information. For a period
     of one (1) year following the most recent substantive activity of the
     parties hereto with respect to a particular Opportunity, the Company shall
     not use such information except in the context of any joint venture with
     Consultant or other participation as agreed by Consultant. The parties
     agree that the intent of this provision is to compensate Consultant for the
     identification of business opportunities and not to convey proprietary
     rights to all contact with an entire organization, not itself a principal
     in the Opportunity, by virtue of an introduction of an Opportunity which
     includes a party which happens to be associated with such organization. The
     parties further agree that the term "Opportunities" does not include any
     existing or potential individuals or businesses that are already known to
     the Company or become known to the Company as a result of Services being
     provided under Section One of this Agreement at the time it is introduced
     by (a) virtue of being generally known to the public; (b) having been
     previously introduced by a third party; or (c) having been independently
     developed by the Company without assistance, directly or indirectly, of
     Consultant.

7.   TERM; TERMINATION. This Agreement may be terminated by either party upon
     fifteen (15) days' notice.

8.   CONFIDENTIAL INFORMATION; TRADE SECRETS. Consultant shall not at any time
     or in any manner, either directly or indirectly, use for the personal
     benefit of Consultant, or divulge, disclose, or communicate in any manner
     any information that is proprietary to the Company without the Company's
     express written consent. Consultant will protect such information and treat
     it as strictly confidential and shall not use or disclose to any person or
     entity any Confidential Information or trade secrets of the Company other
     than as necessary in the fulfillment of the Services. This paragraph shall
     be effective both during the Term hereof and after the termination of this
     Agreement.

<PAGE>

9.   REGISTRATION OF SHARES. Consultant shall have "piggy-back" registration
     rights applicable to all sharres issued pursuant hereto. In addition to the
     foregoing, the Company agrees to register with the Securities and Exchange
     Commission all shares issued hereunder on federal securities Form S-8,
     promulgated under the Securities Act of 1933, as amended, promptly
     following the Company's filing of its first quarterly report on Form
     10-QSB.

10.  INDEPENDENT CONTRACTOR. It is understood and acknowledged by both parties
     that the Consultant is acting as independent contractor and not as an agent
     or employee of the Company and, therefore, may not enter into any
     agreements or incur any obligations or expenses on behalf of the Company
     other than as described herein. The Consultant further agrees not to
     disclose material information about the Corporation and its business and
     shall not be retained by any individual or corporation with similar
     business interests as the Corporation or the targeted acquisitions for a
     period of one year.

11.  COUNTERPARTS. This Agreement may be executed in any number of counterparts
     by one original or facsimile signature of Consultant and Solomon Alliance
     Group, Inc. each of which counterparts, when executed and delivered, shall
     be an original but such counterparts together shall constitute one and the
     same instrument. Any signature on a facsimile copy of the Agreement of any
     document hereafter shall be binding and valid as if made on the original
     copy of the Agreement or document.

12.  CHOICE OF LAW AND INTERPRETATION. This Agreement shall be governed by, and
     shall be construed in accordance with, the laws of the jurisdiction
     designated by the Company. In the event that any provision of this
     Agreement becomes or is declared by an arbitrator to be illegal,
     unenforceable or void, this Agreement shall continue in full force and
     effect without said provision.

13.  ENTIRE AGREEMENT. This Agreement contains the entire agreement of the
     parties and there are no other promises or conditions in any other
     agreement whether oral or written. By their execution hereof, each party
     (for itself and for any of its professional advisors or agents), agrees
     that neither has any claim, or may assert any obligation, monetary or
     otherwise, against the other except as may be set forth herein.

14.  SEVERABILITY. If any provision of this Agreement shall be held to be
     invalid or unenforceable for any reason, the remaining provisions shall
     continue to be valid and enforceable. If a court finds that any provision
     of this Agreement is invalid or unenforceable, but that by limiting such
     provision it would become valid and enforceable, then such provision shall
     be deemed to be written, construed, and enforced as so limited.

15.  DISPUTES AND EXPENSES. In the event of any dispute, the parties agree to
     first submit to mediation pursuant to the rules of the American Arbitration
     Association. If mediation is instituted (or if suit is brought subsequent
     to conclusion of mediation) or an attorney must be paid by any party hereto
     to enforce the terms of this Agreement, or to collect money damages for
     breach hereof, the prevailing party shall be entitled to recover, in
     addition to any other remedy, reimbursement for reasonable attorneys' fees,
     court costs, costs of investigation and other related expenses incurred in
     connection therewith.

16.  MISCELLANEOUS. This Agreement can only be modified by written agreement
     executed by the parties. The parties have been advised by counsel of their
     own choice, and this Agreement is executed by each party voluntarily and
     with full knowledge of its significance. Unless otherwise provided herein,
     any provision hereof which imposes an obligation after termination of this
     Agreement shall survive the termination or expiration hereof and be binding
     on the parties. This Agreement shall be binding on the successors and legal
     representatives of the parties.

IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement as of
the day and year first above written.
