                  ARTICLE II. SALE AND PURCHASE OF COMMON STOCK

    SECTION 2.01. SALE AND PURCHASE.

    (a)  COMMON STOCK. In November 2001, subject to the terms and conditions of
this Agreement,  the Common Stockholder agrees to sell to Purchaser and
Purchaser  agrees to purchase from the Common  Stockholder the  number of
shares of Common  Stock  indicated  as owned by  Stockholder  on Schedule 2.01
of Exhibit A hereto for the amount and type of  consideration  set forth on
Exhibit A hereto.

    b)   MEMBERSHIP  INCREASE.  The  payment  of all  consideration  due in
January  2002  pursuant  to this  Agreement  is contingent upon the overall
membership of Catalyst increasing by 5,000 members on or after January 1, 2002.

    SECTION 2.02. OBLIGATION TO PURCHASE OUTSTANDING INTEREST.

    (a) Subject to the terms and conditions of this  Agreement,  HealthExtras is
    obligated to purchase the remaining  issued and outstanding  Common Stock of
    Catalyst  from Seller no later than March 15th 2003 as indicated on Schedule
    2.02 of Exhibit A hereto for the amount and type of consideration  set forth
    on Exhibit A hereto, as calculated in Section 2.02(b).

    (b) The total  consideration  for Common Stock  purchased under Section 2.02
    (a) shall be  calculated  as the sum of: (1) Eight (8) times the Catalyst Rx
    and  Catalyst  Consultants  calendar  2002  EBITDA,  to the extent  that the
    Catalyst Rx and Catalyst  Consultants  calendar  2002 EBITDA is less than or
    equal to  $1,805,000.00;  and (2) Ten (10) times  Catalyst  Rx and  Catalyst
    Consultants  calendar 2002 EBITDA,  to the extent  Catalyst  EBITDA  exceeds
    $1,805,000.00.  This sum  shall be  multiplied  by a  fraction  representing
    Seller's  proportional  ownership of the issued and outstanding Common Stock
    on the March 2003 Closing Date.

                                     Page 3


    Example:  Assume the combined EBITDA of Catalyst Rx and Catalyst Consultants
    is $2.0  million.  Total  compensation  due in March 2003 will be $3,278,000
    ($2,622,400  in cash and  $655,600  in  HealthExtras  Common  Stock) for the
    remaining 20% of Common Stock:

    [(8 x $1,805,000) x .2] = $2,888,000; plus
    [(10 x $195,000) x .2] = $390,000

    (c) EBITDA for 2002 as  reflected  in the audited  financial  statements  of
    Catalyst  Rx and  Catalyst  Consultants  for that  calendar  year,  shall be
    adjusted to exclude the net financial affect of any business currently under
    contract  or letter  of intent  with  HealthExtras  Rx that is  subsequently
    accounted  for within  Catalyst Rx or  Catalyst  Consultants.  In  addition,
    EBITDA for 2002 shall be adjusted  upward for any specific net  increases in
    the operating expenses for 2002 for Catalyst Rx or Catalyst Consultants that
    are  attributable  to their  affiliation  with  HealthExtras,  including  in
    specific,  increases in employee benefit costs,  management fees, consultant
    fees or on-site  HealthExtras  employees.  At the  discretion  of Seller all
    calculations  related  to these  provisions  shall  be  subject  to  binding
    independent  third party  verification  should any  dispute  arise as to the
    accounting for these  adjustments.  The cost of such  verification  shall be
    shared equally by both parties.

    (d) In  addition,  if Catalyst  signs an  agreement  with any of the clients
    listed on Exhibit B hereto ("Potential Clients") to provide pharmacy benefit
    management  services to Potential  Clients,  consideration for the remaining
    securities  shall be  increased  by an  amount  equal to four  times  EBITDA
    attributable solely to the Potential Clients accounts.  For purposes of this
    paragraph,  EBITDA attributable to Potential Clients shall be defined as net
    revenue minus direct contract costs, such as the cost of any employees hired
    expressly to service Potential Clients.

    SECTION 2.03. THE CLOSINGS.

    (a) Subject to the terms and  conditions  contained in this  Agreement,  the
    closing of the sale to,  and  purchase  by,  Purchaser  of the Common  Stock
    described in Section 2.01 shall occur at 10:00 a.m. on November 14, 2001, at
    the offices of Purchaser at 2273 Research Boulevard,  2nd Floor,  Rockville,
    Maryland  or at such  other  time  and  place  mutually  agreed  upon by the
    parties.  Subject to the terms and conditions  contained in this  Agreement,
    the closing of the sale to, and  purchase  by, the  Purchaser  of the Common
    Stock described in Section 2.02 shall occur at 10:00 a.m. on March 14, 2003,
    at the offices of Purchaser or at such other time and place mutually  agreed
    upon by the parties.  Each  closing  shall be a "November  2001  Closing" or
    "March 2003 Closing," as applicable,  or  collectively  the  "Closings." The
    days on which the Closings occur shall be the "Closing  Date(s),"  "November
    2001 Closing Date" or "March 2003 Closing Date," as applicable.

    (b) At the Closings or such other dates as the parties may agree, the Common
    Stockholder shall deliver to the Purchaser  certificates,  registered in the
    name  of the  Purchaser,  for the  shares  of  Common  Stock  being  sold to
    Purchaser  by the  Common  Stockholder  as set  forth on  Exhibit  A hereto,
    against  payments of the purchase  price set forth on Exhibit A hereto.  The
    payments of the purchase

                                     Page 4


    prices will be by wire transfer,  check,  or other method  acceptable to the
    Common Stockholder.

    (c) If at the  Closings  any of the  conditions  specified in Article VII as
    condition to the obligations of a party shall not have been fulfilled,  that
    party at its election,  shall be relieved of all its obligations  under this
    Agreement  without thereby waiving any other rights it may have by reason of
    such failure or such nonfulfillment.

    SECTION 2.04. CALCULATION OF HEALTHEXTRAS COMMON STOCK AS CONSIDERATION.
    The number of shares of  HealthExtras  Common  Stock  provided to Seller
under this Agreement shall be calculated by dividing the value of HealthExtras
Common Stock consideration listed in Exhibit A by the applicable HealthExtras
Closing Price.

                       ARTICLE III. ADDITIONAL AGREEMENTS

    SECTION 3.01. BOARD OF DIRECTORS.

size of the Board of Directors of Catalyst (the "Board")  to three (3)  members;
and (ii) to  consent  to the  nominees  of the Purchaser to fill the newly
created Board seats.

                         ARTICLE IV. REPRESENTATIONS AND

    Section 4.03 of the Catalyst Disclosure  Schedule,  there are no outstanding
    options,  warrants,  convertible  securities,  calls,  rights,  commitments,
    preemptive  rights or agreements or  instruments  or  understandings  of any
    character  to  which  Catalyst  is a party or by which  Catalyst  is  bound,
    obligating  Catalyst  to  issue,  deliver  or sell,  or cause to be  issued,

    SECTION 4.08. FINANCIAL STATEMENTS AND OTHER INFORMATION.

    (a) Catalyst has delivered to Purchaser to the best of Catalyst's  knowledge

    Catalyst as of December 31, 1999, December 31, 2000 and October 31, 2001 and
    the related unaudited  statements of operations,  statements of shareholders
    equity (deficit), statements of cash flows (the "Financial Statements"). The

    sales price to reflect the agreed upon excess working capital.

                                     Page 7


    (b) The  Financial  Statements  to the best of  Catalyst's  and the Seller's
    knowledge  are in  accordance  with the books and records of Catalyst,  have
    been prepared in accordance with generally  accepted  accounting  principles
    consistently  applied throughout the periods covered thereby and the balance
    sheets  included  therein  present fairly as of their  respective  dates the
    financial condition of Catalyst.  To the best of Catalyst's  knowledge,  all
    material liabilities and obligations,  whether absolute, accrued, contingent
    or otherwise,  whether direct or indirect, and whether due or to become due,
    which existed at the date of such Financial  Statements  have been disclosed
    in the balance  sheets  included in the Financial  Statements or in notes to
    the Financial Statements to the extent such liabilities were required, under
    generally accepted accounting principles, to be so disclosed. To the best of
    Catalyst's knowledge, the statements of operations,  of shareholders' equity
    (deficit),  and of cash flows included in the Financial  Statements  present
    fairly the results of operations,  shareholders'  equity  (deficit) and cash
    flows of  Catalyst  for the  periods  indicated.  To the best of  Catalyst's
    knowledge, the statements of operations included in the Financial Statements
    do not  contain any  material  items of special or  non-recurring  income or
    other  income  not  earned  in the  ordinary  course of  business  except as
    expressly specified therein.

    (c) To the best of Catalyst's  knowledge,  the accounts and notes receivable
    of Catalyst  listed on the latest balance sheet of Catalyst  included in the
    Financial  Statements,  are, net of reserves reflected on the balance sheet,
    collectible  in full  over  the  period  of  usual  trade  terms  (by use of
    Catalyst's  normal  collection  methods  without  resort  to  litigation  or
    reference  to a  collection  agency),  and there do not exist any  defenses,
    counterclaims  and set-offs  which could  materially  adversely  affect such
    receivables,  and all such  receivables are actual and bona fide receivables
    representing  obligations  for the total dollar amount  thereof shown on the
    books of Catalyst. Catalyst has fully performed all obligations with respect
    thereto which it was obligated to perform.

    (d) Since October 31, 2001, to the best of Catalyst's  knowledge,  there has
    been no Material Adverse Change in Catalyst,  including  whether as a result
    of any legislative or regulatory change,  revocation of any License or right
    to do business,  fire, explosion,  accident,  casualty, labor trouble, riot,
    condemnation, or act of God.

    SECTION 4.09. NO UNDISCLOSED LIABILITIES.
    Except  as  set  forth  in  the  notes  to  the  Financial  Statements,  the
liabilities  on the latest  balance sheet of Catalyst  included in the Financial
Statements  to the  best of  Catalyst's  knowledge  consist  solely  of  accrued
obligations  and  liabilities  incurred by Catalyst  in the  ordinary  course of
business  to  Persons  which  are  not  Affiliates  of  Catalyst.  There  are no
liabilities  of  Catalyst  of any  kind  whatsoever  to the  best of  Catalyst's
knowledge,  whether or not accrued and whether or not  contingent  or  absolute,
including without  limitation  documentary or standby letters of credit,  bid or
performance  bonds,  or  customer  or third  party  guarantees,  other  than (a)
liabilities disclosed in the Financial  Statements,  (b) liabilities for routine
pharmacy  claims which have arisen after October 31, 2001 in the ordinary course
of Catalyst's business and consistent with past practice, (c) liabilities (other
than those  covered by clause (b) above)  which in the  aggregate  do not exceed
$25,000 and which have arisen after  October 31, 2001 in the ordinary  course of
business and  consistent  with past  practice  (none of which is a liability for
breach of contract, breach of warranty, tort, infringement claim or lawsuit or a

                                     Page 8



liability  to repay or refund to any Person any amounts  previously  received by
Catalyst) and (d) liabilities  incurred in connection with the execution of this
Agreement  which,  individually  or in the  aggregate,  do not  have a  Material
Adverse  Effect.  To the best of  Catalyst's  knowledge,  there are no  asserted
claims for  indemnification  by any  Person  against  Catalyst  under any law or
agreement or pursuant to Catalyst's  Certificate of Incorporation or Bylaws, and
Catalyst  is unaware of any facts or  circumstances  that might give rise to the
assertion of such a claim against Catalyst thereunder.

Catalyst taken on or prior to the date hereof have been duly authorized, adopted

Incorporation  and Bylaws and have been duly  recorded in  Catalyst's  corporate
minute books (true,  correct and complete copies of which have been delivered to
or made available for inspection by Purchaser).


    SECTION 4.11. TAXES.
    Except for the possibility that Catalyst may need to file an amended federal
return for 2000 and may have  underpaid  its estimated tax payments for 2001, to
the best of Catalyst's  knowledge:  (i) Catalyst has prepared in a substantially
correct manner and has filed all federal,  state, local, and foreign tax returns
and  reports  heretofore  required  to be filed by them and have  paid all taxes
shown as due thereon;  and (ii) no taxing  authority has asserted any deficiency
in the payment of any tax or informed the Catalyst that it intends to assert any
such deficiency or to make any audit or other  investigation of Catalyst for the
purpose of  determining  whether  such a deficiency  should be asserted  against
Catalyst.

    SECTION 4.12. LITIGATION.
    Except as described in Section  4.12 of the  Catalyst  Disclosure  Schedule,
there are no material actions, suits, proceedings,  orders,  investigations,  or
claims  pending  or,  to the  best of the  Sellers'  and  Catalyst's  knowledge,
threatened  against Catalyst or any property of either,  at law or in equity, or
before or by any governmental department,  commission, board, bureau, agency, or
instrumentality,  or by on  behalf  of any  person,  group or class of  persons,
corporation,  partnership or other legal entity;  Catalyst is not subject to any
arbitration  proceedings under collective bargaining agreements or otherwise or,
to  the  best  of  the  Seller's  and  Catalyst's  knowledge,  any  governmental
investigations  or inquiries;  and, to the best  knowledge of the Seller and the
Board of Directors and responsible  officers of Catalyst,  there is no basis for
any of the foregoing.

    SECTION 4.13. COMPLIANCE WITH LAWS.
    To the best of Catalyst's  knowledge,  Catalyst has  substantially  complied
with  all  applicable  laws  (including  rules,   regulations,   codes,   plans,
injunctions,  judgments, orders, decrees, rulings and charges thereunder) of any
Governmental Entity relating to or affecting the operation, conduct or ownership
of its  properties  or  businesses.  To the  best of  Catalyst's  knowledge,  no
investigation or review by any Governmental Entity (including without limitation
any audit or  similar  review by any  federal,  foreign,  state or local  taxing
authority)  with  respect to  Catalyst  is pending  or  threatened,  nor has any
Governmental  Entity  indicated to Catalyst an intention to conduct the same. To
the best of Catalyst's  knowledge,  neither Catalyst nor any director,  officer,
consultant  or employee  of Catalyst  (in all  instances,  in their  capacity as
such), is in default with respect to any order, writ, injunction or decree known

                                     Page 9


to or served upon Catalyst by any Governmental Entity. To the best of Catalyst's
knowledge, there is no existing law, rule, regulation or order, whether federal,
state, local,  municipal or foreign, which would prohibit or materially restrict
Catalyst from, or otherwise  materially adversely affect Catalyst in, conducting
its business in any  jurisdiction  in which it is now conducting  business or in
which it currently proposes to conduct business.

    SECTION 4.14. TITLE TO ASSETS.
    To the best of Catalyst's  knowledge,  Catalyst has good and insurable title
to its properties and assets (including any intellectual  property asset such as
any trademark, service mark, trade name or copyright) and property acquired in a
judicial  foreclosure  proceeding or by way of a deed in lieu of  foreclosure or
similar transfer whether real or personal,  tangible or intangible, in each case
free and  clear  of any  liens,  security  interests,  encumbrances,  mortgages,
pledges,  restrictions,  charges or rights or  interests  of others,  except (i)
liens for taxes not yet due and  payable,  (ii)  pledges to secure  deposits and
other  liens  incurred  in the  ordinary  course of  business,  and  (iii)  such
easements,  restrictions  and  encumbrances,  if  any,  as are not  material  in
character,  amount or extent,  and do not materially  detract from the value, or
materially  interfere with the present use of the properties  subject thereto or
affected  thereby.  Each lease pursuant to which Catalyst is lessee or lessor is
valid and in full force and effect and neither  Catalyst,  nor to its knowledge,
any other party to any such lease is in default or in  violation of any material
provisions of any such lease. To the best of Catalyst's knowledge,  all material
tangible  properties of Catalyst are in a good state of  maintenance  and repair
(normal  wear and  tear  excepted),  conform  with  all  applicable  ordinances,
regulations  and zoning laws and are considered by Seller to be adequate for the
current business of Catalyst.


    SECTION 4.15. CONTRACTS.
    To the best of Catalyst's knowledge, the consummation of the Purchase or the
other  transactions  contemplated  hereby  will not result in any  violation  or
termination  of,  default or loss of benefit  under,  or give rise to a right of

    liability to such employee or officer or any other person.

    (e) Expect as set forth in Section 4.16 of the Catalyst Disclosure Schedule,
    to the best of Catalyst's  knowledge the  consummation  of the  transactions
    contemplated by this Agreement will not (either alone or in conjunction with
    another  event,  such as a  termination  of  employment  or other  services)
    entitle  any  employee  or  other  person  to  receive  severance  or  other
    compensation which would not otherwise be payable absent the consummation of
    the transactions contemplated by this Agreement or cause the acceleration of
    the time of  payment  or  vesting  of any  award or  entitlement  under  any
    Employee  Plan,  other than as may be made by Seller from his proceeds  from
    this Agreement.

    SECTION 4.17.  LABOR MATTERS.
    Catalyst is not a party to or otherwise  bound by any collective  bargaining
agreement,  contract or other agreement or  understanding  with a labor union or
labor  organization,  nor, as of the date hereof, is Catalyst the subject of any
proceeding  asserting that Catalyst has committed an unfair labor practice or is
seeking to compel it to bargain with any labor union or labor  organization nor,

complete   description  of  all  insurance  policies  covering   Catalyst,   its
businesses,  employees,  agents and assets. To the best of Catalyst's knowledge,
each such  policy is in full force and effect and  Catalyst  believes  each such
policy  is of  the  type  and in  the  amount  customarily  carried  by  Persons
conducting  businesses or owning assets similar to those of the Catalyst. To the
best of Catalyst's knowledge,  such policies shall not, pursuant to their terms,
in any way be affected by, or  terminate or lapse by reason of, this  Agreement.
To the best of Catalyst's knowledge, all premiums with respect to such insurance
policies  have been paid on a timely  basis,  and no notice of  cancellation  or
termination  has been received  with respect to any such policy.  To the best of
Catalyst's knowledge,  Catalyst has not failed to give any notice or present any
claim thereunder in due and timely fashion. To the best of Catalyst's knowledge,
there are no pending  claims  against such insurance by or on behalf of Catalyst
as to which the  insurers  have denied  coverage or otherwise  reserved  rights.
Catalyst  has not been  refused  any  insurance  with  respect  to its assets or

                                    Page 11

be paid by Catalyst.

    Section 4.21. Suppliers and Customers.

    (a) Section  4.21 of the  Catalyst  Disclosure  Schedule  identifies  all of
    Catalyst's  material  customers  and  suppliers.  To the best  knowledge  of
    Catalyst  or  Seller no  material  customer  or  supplier  intends  to cease
    purchasing from, selling to or dealing with Catalyst nor has any information
    been  brought to their  attention  which might lead them to believe any such
    customer or supplier  intends to alter in any material respect the amount of
    such  purchases,  sales  or the  extent  of  dealings  with  Catalyst  or to
    materially  alter  such  purchases,  sales or  dealings  in the event of the
    consummation of the Purchase.  No customer has informed  Catalyst in writing
    that it intends to cancel  outstanding  or currently  anticipated  contracts
    with  Catalyst.  Catalyst  has  notified  Purchaser  of all known  potential
    terminations.
